text: Dielectric metasurfaces provide a unique platform for efficient harmonic generation
and optical wavefront manipulation at the nanoscale. Tailoring phase and amplitude
of a nonlinearly generated wave with a high emission efficiency using resonance-based
metasurfaces is a challenging task that often requires state-of-the-art numerical
methods. Here, we propose a simple yet effective approach combining a sampling
method with a Monte Carlo approach to design the third-harmonic wavefront generated
by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using
this approach, we theoretically demonstrate the full nonlinear 2π phase control
with a uniform and highest possible amplitude in the considered parameter space,
allowing us to design metasurfaces operating as third harmonic beam deflectors
capable of steering light into a desired direction with high emission efficiency.
The TH beam deflection with a record calculated average conversion efficiency
of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be
widely applied as alternative to commonly used optimization algorithms with higher
complexity and implementation effort for the design of metasurfaces with other
holographic functionalities.

text: Faradaic reactions including charge transfer are often accompanied with diffusion
limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with
a fast ion transport can combine both - charge transfer and fast diffusion inside
their porous structure. To study remaining diffusion limitations caused by particle
morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene
(Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF
particles. Both morphologies are systematically characterized and evaluated for
redox-active Li+ ion storage. The redox mechanism is investigated by means of
X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are
compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry
and impedance spectroscopy. A significant influence of particle morphology for
2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.
This study opens the path for optimization of redox active porous structures to
overcome diffusion limitations of Faradaic processes.

text: "Abstract\r\n Background\r\n
\ Occupational health interventions for leaders are underrepresented
in small and medium-sized enterprises (SMEs). When creating and developing effective
occupational health interventions, identification of the specific needs of the
target group is regarded as an essential step before planning an intervention.
Therefore, the aim of this study was (1) to examine the subjectively experienced
work-related stressors of leaders in small and medium-sized IT and technological
services enterprises, (2) to explore coping behaviors leaders use to deal with
the experienced work-related stressors, (3) to investigate resources supporting
the coping process and (4) to identify potentially self-perceived consequences
resulting from the experienced stressors.\r\n \r\n
\ Methods\r\n Ten
semi-structured interviews with leaders in small and medium-sized IT and technological
services enterprises were conducted. The interviews were transcribed and analyzed
with content-structuring qualitative content analysis in accordance to Kuckartz.\r\n
\ \r\n Results\r\n
\ Leaders in small and medium-sized IT and technological
services enterprises experience various stressors caused by work organization
as well as industry-related stressors and other work-related stressors. To address
the experienced stressors, leaders apply problem focused coping behaviors (e.g.
performing changes on structural and personal level), emotional focused coping
behaviors (e.g. balancing activities, cognitive restructuring) as well as the
utilization of social support. Helpful resources for the coping process include
organizational, social and personal resources. As a result of the experienced
work-related stressors, interviewees stated to experience different health impairments,
negative effects on work quality as well as neglect of leisure activities and
lack of time for family and friends.\r\n \r\n
\ Conclusion\r\n The
identified experienced work-related stressors, applied coping behaviors, utilized
resources and emerging consequences underpin the urgent need for the development
and performance of health-oriented leadership interventions for leaders in small
and medium- sized IT and technological services. The results of this study can
be used when designing a target-oriented intervention for the examined target
group.\r\n "

text: "Abstract\r\n\t \r\n\t
\ Objective:\r\n\t To systematically review
the impact of choice architecture interventions (CAI) on the food choice of healthy
adolescents in a secondary school setting. Factors potentially contributing to
the effectiveness of CAI types and numbers implemented and its long-term success
were examined.\r\n\t \r\n\t \r\n\t
\ Design:\r\n\t PUBMED and Web of Science
were systematically searched in October 2021. Publications were included following
predefined inclusion criteria and grouped according to number and duration of
implemented interventions. Intervention impact was determined by systematic description
of the reported quantitative changes in food choice and/or consumption. Intervention
types were compared with regards to food selection and sustained effects either
during or following the intervention.\r\n\t \r\n\t \r\n\t Setting:\r\n\t
\ CAI on food choice of healthy adolescents in secondary schools.\r\n\t
\ \r\n\t \r\n\t Participants:\r\n\t
\ Not applicable\r\n\t \r\n\t \r\n\t
\ Results:\r\n\t Fourteen studies were included;
four randomized controlled trials and five each of controlled or uncontrolled
pre-post design, respectively. Four studies implemented a single CAI type, with
ten implementing > 1. Three studies investigated CAI effects over the course
of a school year either by continuous or repeated data collection, while ten studies’
schools were visited on selected days during intervention. Twelve studies reported
desired changes in overall food selection, yet effects were not always significant,
and appeared less conclusive for longer term studies.\r\n\t \r\n\t
\ \r\n\t Conclusions:\r\n\t
\ This review found promising evidence that CAI can be effective in
encouraging favorable food choices in healthy adolescents in a secondary school
setting. However, further studies designed to evaluate complex interventions are
needed.\r\n\t "

text: ' Background: Establishing a healthy lifestyle has a great potential
to reduce the prevalence of non-communicable diseases (NCDs) and their risk factors.
NCDs contribute immensely to the economic costs of the health care system arising
from therapy, medication use, and productivity loss. Aim: The aim of this study
was to evaluate the effect of the Healthy Lifestyle Community Program (cohort
2; HLCP-2) on medication use and consequently on medication costs for selected
NCDs (diabetes, hypertension, and dyslipidemia). Methods: Data stem from a 24-month
non-randomised, controlled intervention trial aiming to improve risk factors for
NCDs. Participants completed questionnaires at six measurement time points assessing
medication use, from which costs were calculated. The following medication groups
were included in the analysis as NCD medication: glucose-lowering medications
(GLM), antihypertensive drugs (AHD) and lipid-lowering drugs (LLD). Statistical
tests for inter- and intra-group comparison and multiple regression analysis were
performed. Results: In total, 118 participants (intervention group [IG]: n = 79;
control group [CG]: n = 39) were considered. Compared to baseline medication use
decreased slightly in the IG and increased in the CG. Costs for NCD medication
were significantly lower in the IG than in the CG after 6 ( p = 0.004), 12 ( p = 0.040),
18 ( p = 0.003) and 24 months ( p = 0.008). After multiple regression analysis
and adjusting for confounders, change of costs differed significantly between
the groups in all final models. Conclusion: The HLCP-2 was able to moderately
prevent an increase of medication use and thus reduce costs for medication to
treat NCDs with the greatest impact on AHD. Trial

text: A previous follow-up of the GINIplus study showed that breastfeeding
could protect against early eczema. However, effects diminished in adolescence,
possibly indicating a “rebound effect” in breastfed children after initial protection.
We evaluated the role of early eczema until three years of age on allergies until
young adulthood and assessed whether early eczema modifies the association between
breastfeeding and allergies. Data from GINIplus until 20-years of age (N = 4058)
were considered. Information on atopic eczema, asthma, and rhinitis was based
on reported physician’s diagnoses. Adjusted Odds Ratios (aOR) were modelled by
using generalized estimating equations. Early eczema was associated with eczema
(aORs = 3.2–14.4), asthma (aORs = 2.2–2.7), and rhinitis (aORs = 1.2–2.7) until
young adulthood. For eczema, this association decreased with age (p-for-interaction
= 0.002–0.006). Longitudinal models did not show associations between breastfeeding
and the respective allergies from 5 to 20 years of age. Moreover, early eczema
generally did not modify the association between milk feeding and allergies except
for rhinitis in participants without family history of atopy. Early eczema strongly
predicts allergies until young adulthood. While preventive effects of full breastfeeding
on eczema in infants with family history of atopy does not persist until young
adulthood, the hypothesis of a rebound effect after initial protection cannot
be confirmed.

text: "Variational Quantum Algorithms (VQAs), such as the Quantum Approximate\r\nOptimization
Algorithm (QAOA) of [Farhi, Goldstone, Gutmann, 2014], have seen\r\nintense study
towards near-term applications on quantum hardware. A crucial\r\nparameter for
VQAs is the depth of the variational ansatz used - the smaller\r\nthe depth, the
more amenable the ansatz is to near-term quantum hardware in\r\nthat it gives
the circuit a chance to be fully executed before the system\r\ndecoheres. This
potential for depth reduction has made VQAs a staple of Noisy\r\nIntermediate-Scale
Quantum (NISQ)-era research.\r\n In this work, we show that approximating the
optimal depth for a given VQA\r\nansatz is intractable. Formally, we show that
for any constant $\\epsilon>0$, it\r\nis QCMA-hard to approximate the optimal
depth of a VQA ansatz within\r\nmultiplicative factor $N^{1-\\epsilon}$, for $N$
denoting the encoding size of\r\nthe VQA instance. (Here, Quantum Classical Merlin-Arthur
(QCMA) is a quantum\r\ngeneralization of NP.) We then show that this hardness
persists even in the\r\n\"simpler\" setting of QAOAs. To our knowledge, this yields
the first natural\r\nQCMA-hard-to-approximate problems. To achieve these results,
we bypass the need\r\nfor a PCP theorem for QCMA by appealing to the disperser-based
NP-hardness of\r\napproximation construction of [Umans, FOCS 1999]."

text: 'Ernährungsarmut wird als Problem in Deutschland weitgehend vernachlässigt.
Von materieller Ernährungsarmut betroffen sind Menschen, denen es aufgrund fehlender
finanzieller Mittel nicht möglich ist, sich gesundheitsfördernd zu ernähren. Etwa
3,5 % der Bevölkerung (rund drei Millionen Menschen) sind durch materielle Ernährungsarmut
gefährdet. Damit einher geht oft auch soziale Ernährungsarmut, die Menschen von
der sozialen Teilhabe ausschließt, die z. B. durch gemeinsames Essen ermöglicht
wird. Essen ist nicht nur von Bedeutung für die körperliche Gesundheit, sondern
auch zentral für die psychische Gesundheit und das Wohlbefinden sowie für die
soziale Zugehörigkeit, was sich wiederum auf die körperliche Gesundheit auswirkt.
Die sozialen Funktionen des Essens werden vielfach übersehen – und bei der Berechnung
des Regelbedarfs ausgeblendet. Gerade die Corona-Pandemie hat gezeigt, wie fehlende
soziale Kontakte und sozialer Ausschluss sich auf die physische, psychische und
soziale Gesundheit auswirken können. Aus Sicht des WBAE (Wissenschaftliche Beirat
für Agrarpolitik, Ernährung und gesundheitlichen Verbraucherschutz) ist deshalb
der integrative Blick auf die materielle und soziale Ernährungsarmut zentral,
da sie sich gegenseitig verstärken können. Diese Stellungnahme befasst sich mit
der Frage, wie sich die Corona-Pandemie auf von Ernährungsarmut gefährdete Menschen
ausgewirkt hat und was daraus gelernt werden kann. Ein wichtiger Aspekt ist der
zeitweilige Wegfall von Essensangeboten in Kitas, Schulen, Tafeln und anderen
karitativen Essensangeboten, die ein Sicherheitsnetz für Menschen in Ernährungsarmut
darstellen. Die Stellungnahme zieht auf dieser Basis auch Schluss-folgerungen
zur Ernährungsarmut außerhalb von Pandemiebedingungen. Im Hinblick auf die Notwendigkeit
der Vermeidung von Fehlernährung in Haushalten, die von Ernährungsarmut bedroht
sind, kommt der WBAE zu dem Schluss, dass diese Risikogruppe während der Pandemie
nicht ausreichend im Fokus der Maßnahmen zur Abmilderung der Pandemiefolgen stand.
Dies zeigt sich schon daran, dass kaum Daten erhoben wurden. Deutschland verfügt
über kein klares Indikatoren- und Zielsystem und kein Monitoring zur Ernährungsarmut.
Die wenigen vorhandenen Daten weisen auf problematische Entwicklungen hin. Insgesamt
wurden durch den Bund sehr umfangreiche Mittel zur Bewältigung der wirtschaftlichen
und sozialen Folgen der Corona-Pandemie und zur Einkommenssicherung während der
Pandemie eingesetzt. Dies ist unter dem Blickwinkel „Ernährungsarmut” positiv
zu bewerten. Es ist davon auszugehen, dass diese Maßnahmen verhindert haben, dass
noch mehr Haushalte von Ernährungsarmut betroffen waren. Insgesamt zeigt die Analyse
jedoch, dass es kaum gezielte Maßnahmen gab, um den Ausfall von Kita- und Schulernährung
durch alternative Formen der Bereitstellung von Lebensmitteln oder einer warmen
Mahlzeit aufzufangen. Maßnahmen auf Bundesebene fehlten, um Länder, Kommunen und
nicht-staatliche Organisationen dabei zu unterstützen. Auswertungen der Pandemiemaßnahmen
vergleichbarer Länder zeigen, dass dort schnelle und flexible Maßnahmen zur Bereitstellung
von Lebensmitteln eine wichtige Rolle gespielt haben, um armutsgefährdete Haushalte
zu unterstützen. In Deutschland wurden vorwiegend finanzielle Transfers genutzt,
z. T. zeitlich verzögert und wenig zielgruppenspezifisch. Vor diesem Hintergrund
hat der WBAE mögliche Maßnahmen gegen Ernährungsarmut – in Krisen, aber auch generell
– untersucht: (1) finanzielle Transfers (einmalig oder fortlaufend), (2) Lebensmittelgutscheine
(„Voucher“), (3) Lebensmittelpakete und (4) warme Mahlzeiten, wobei die letzten
beiden Optionen jeweils zur Abholung oder zur Auslieferung angeboten werden können.
Die untersuchten internationalen Beispiele zeigen Möglichkeiten, wie z. T. mit
schnellen und teilweise innovativen Ansätzen auf Lockdown-Maßnahmen reagiert wurde.
Im Grundsatz spricht aus Sicht des WBAE aber vieles für das deutsche System zur
Bekämpfung der Ernährungsarmut, das im Kern auf einem Bürgergeld beruht. Ein solches
Bürgergeld muss jedoch ausreichend sein, um materielle und soziale Ernährungsarmut
zu vermeiden. Die aktuellen, im Bürgergeld für Essen und Getränke zur Verfügung
stehenden Beträge entsprechen allerdings nicht diesem Anspruch. Bei der Einführung
des Bürgergelds im Jahr 2023 wurde zwar zeitnah auf die hohe Inflation reagiert.
Die Berechnungsmethodik für die Bedarfsermittlung wurde aber nicht angepasst,
sodass der Regelsatz nach wie vor nicht für eine gesundheitsfördernde Ernährung
ausreicht. Die soziale Funktion von Ernährung wird bei der Berechnung des Regelsatzes
nicht berücksichtigt. Um bei akutem Handlungsbedarf, wie z. B. auch bei der derzeitigen
Inflation, schneller reagieren zu können, sollten außerdem Systeme zur Auszahlung
sozial differenzierter „Krisentransfers” an vulnerable Haushalte mit geringem
Verwaltungsaufwand ermöglicht werden. Darüber hinaus sollte für den zentralen
Bereich der Kinder-ernährung der Schutz einer adäquaten Grundsicherung durch einen
Systemwechsel zu einer integrativen, beitragsfreien und somit nicht-diskriminierenden
Kita- und Schulverpflegung ergänzt werden, die zudem den DGE-Qualitätsstandards
entspricht. Schließlich sollte der Staat privates, ehrenamtliches Engagement ergänzend
fördern, z. B. durch Infrastrukturunterstützung bei karitativen Essensangeboten.
Eine Herausforderung der Gestaltung von karitativen Lebensmittelangeboten besteht
darin, dass sie oft als stigmatisierend und beschämend wahrgenommen werden und
der Nachweis eines Anspruches teils schwierig ist. Zudem bestehen oft nur wenige
Wahlmöglichkeiten, sodass individuelle Präferenzen oder Unverträglichkeiten nur
sehr eingeschränkt berücksichtigt werden können. Im Hinblick auf die soziale Dimension
der Ernährung kommt hinzu, dass wichtige soziale Funktionen des Essens, wie das
gemeinsame Essen, also Kommensalität, nicht oder nur sehr eingeschränkt ermöglicht
wird. Auch bleiben diejenigen, die versorgt werden, dabei meist unter sich. Vor
dem Hintergrund dieser Gesamteinschätzung empfiehlt der WBAE die folgenden, in
Abbildung Z 1 dargestellten Maßnahmen (siehe Beitrag). Zusammenfassend betont
der WBAE die in Deutschland weiterhin unterschätzten Risiken materieller und sozialer
Ernährungsarmut. Im Rahmen der geplanten Nationalen Ernährungsstrategie der Bundesregierung
sollte dem Thema Ernährungsarmut aus Sicht des WBAE eine herausgehobene Bedeutung
zugemessen werden.'

text: AbstractObjectiveConcerns
about short‐ and long‐term consequences of repetitive heading contributed to heading
restrictions in youth football in some countries. This prospective longitudinal
cohort study aims to describe heading exposure in children's and youth football
over two seasons using standardized video analysis.MethodsAll
matches and training sessions of a male Under‐11 (n = 29),
Under‐15 (n = 28), Under‐19 (n = 38),
and female Under‐17 (n = 39) team were videotaped during
the seasons 2019–2020 and 2020–2021. Heading frequencies and characteristics were
analyzed. Individual heading exposure is presented as average incidence rates
(IR) per 1000 match/training hours.ResultsIn
275 matches and 673 training sessions, 22 921 headers were observed. Heading IR
per player in matches was 1256 (Under‐11 m), 1608 (Under‐15 m), 1050 (Under‐17 f),
and 1966 (Under‐19 m). In training sessions, IR per player was 739 (Under‐11 m),
2206 (Under‐15 m), 1661 (Under‐17 f), and 1419 (Under‐19 m). Five Under‐15 males
headed the ball five to eight times per training on average. Most headers were
performed without heading duels. Flight distance was predominantly 5–20 m (54%)
in matches and <5 m (65%) in training. While head impact location most frequently
was at frontal areas, one‐third of all headers in Under‐11 in matches hit temporal,
parietal, and occipital parts of the head.ConclusionHeading
incidence was low in the youngest age group, whereas (predominantly five) Under‐15
males showed very high heading exposures in training. In assessment and regulation
of heading burden, training sessions and individual heading behavior should specifically
be addressed. Recommendations for heading the ball in practice should account
for individual and age‐related differences.

text: Modern companies often face various challenges in concept development of products
or systems. Design engineers prepare initial concepts as 3D models. These are
then simulated by computational engineers. If requirements are not met, this necessitates
an iterative process that runs between the design and computation departments
until a valid concept is created. Design methods such as topology optimization
are often used here. The upcoming result is then attempted to be adapted to certain
manufacturing processes. These iteration loops can sometimes take a very long
time, since the model construction and structural optimization generate large
computational efforts. The present work shows on an example a methodical approach,
which represents a first proof of concept, to solving this problem, including
a description of methods and techniques, as well as possible problems in a detailed
analysis concerning training data for neural networks and their abstraction capabilities.
It is evident that additional research work needs to be conducted for further
utilization in order to address all arising questions.

text: Ein Trend in der Produktion sind individualisierte Produkte und damit eine
höhere Variantenvielfalt, die idealerweise durch effiziente Produktionsprozesse
hergestellt werden. Effizienz bedeutet in diesem Fall, dass die Produkte kostengünstig
und bedarfsgerecht hergestellt werden. Der Trend geht hierbei auch in der Massenproduktion
zu einer flexiblen Produktion, um das gebundene Kapital zu reduzieren und zeitnah
auf Kundenwünsche reagieren zu können. Dies führt zu einem häufigeren Umrüsten
der Werkzeuge in den Maschinen und somit zu einem immer häufigeren Einrichten
der Prozesse.In dieser Arbeit wird eine Systematik für ein adaptives Einrichtassistenzsystem
entwickelt, welches den Maschinenbediener beim Einrichten mithilfe eines definierten
Vorgehens durch den Prozess leitet. Der Bediener wird dabei unterstützt die momentane
Produktqualität zu bewerten und bekommt einen quantitativen Vorschlag zur Variation
der Justagemöglichkeiten. So kann der Einrichtprozess zielgerichteter und fehlerfreier
durchgeführt werden. Ermöglicht wird dies durch die Abbildung des notwendigen
Expertenwissens in datengetriebenen Modellen. Mithilfe des so abgebildeten Expertenwissens
werden optimierte Einstellungen berechnet und am Werkzeug eingestellt. Es ist
nicht davon auszugehen, dass das virtualisierte Expertenwissen die Realität allumfassend
abbilden und alle akuten Umwelteinflüsse messtechnisch ermittelt werden können.
Etwaige Abweichungen der Produktqualität werden direkt in der entwickelten Optimierung
und bei Bedarf mithilfe der vorgeschlagenen Kompensationsstrategie eliminiert.Die
Systematik wird anhand eines Folgeverbundprozesses validiert. Nach der Analyse
des Prozesses werden die wesentlichen Komponenten für das System entwickelt und
mithilfe von Versuchen und Simulationen die Funktionsfähigkeit erfolgreich nachgewiesen.

text: A trend in production are individualized products and thus a higher number
of variants, which are ideally produced by efficient production processes. In
this case, efficiency means that the products are manufactured at low cost and
in line with demand. This trend, flexible manufacturing, is also valid for mass
production, in order to reduce tied up capital and still be able to react promptly
to customer demands. This leads to more frequent retooling in the machines and
thus also to an increasingly frequent setting up of the processes.In this thesis,
a systematic for an adaptive set-up assistant is developed, which guides the machine
operator through the process during setup. The machine operator is supported in
evaluating the current product quality and receives a quantitative proposal for
the variation of the adjustment possibilities. Thus, the set-up process can be
carried out in a more targeted and error-free manner. This is made possible by
mapping the necessary expert knowledge in data-driven models. The expert knowledge
is used to calculate optimized settings and adjust them on the tool. It cannot
be assumed that virtualized expert knowledge will comprehensively map reality
and that all acute environmental influences can be measured. Any deviations in
product quality are directly eliminated in the developed optimization and, if
necessary, with a proposed compensation strategy.The system is validated with
a progressive tool. After analyzing the process, the essential components for
the system are developed and their functionality is successfully demonstrated
by means of tests and simulations.

text: "AbstractEndurance training has been shown
to be effective in treating adolescents with major depressive disorder (MDD).
To integrate endurance training into the therapeutic setting and the adolescents'
daily lives, the current performance status of the adolescents should be accurately
assessed. This study aims to examine adolescents with MDD concerning exhaustion
criteria during a cardiopulmonary exercise test (CPET), as well as to compare
the values obtained thereon with sex- and age-related control values. The study
included a retrospective examination of exhaustion criteria ((i) oxygen consumption
(V̇O2) plateau, (ii) peak respiratory exchange ratio (RERpeak) > 1.0,
(iii) peak heart rate (HRpeak) ≥ 95% of the age-predicted
maximal HR, and (iv) peak blood lactate concentration (BLCpeak) > 8.0 mmol⋅L−1)
during a graded CPET on a cycle ergometer in adolescents with MDD (n = 57). Subsequently,
maximal V̇O2, peak minute ventilation, V̇O2
at the first ventilatory threshold, and peak work rate of participants who met
at least two of four criteria were compared with published control values using
an independent-sample t-test. Thirty-three percent of the total population achieved
a V̇O2 plateau and 75% a RERpeak > 1.0.
The HR and BLC criteria were met by 19% and 22%, respectively. T-test results
revealed significant differences between adolescents with MDD and control values
for all outcomes. Adolescents with MDD achieved between 56% and 83% of control
values. Conclusions: The study shows
that compared with control values, fewer adolescents with MDD achieve the exhaustion
criteria on a CPET and adolescents with MDD have significantly lower cardiorespiratory
fitness. Clinical trial registration:
No. U1111-1145–1854.\r\n
\ \r\n What
is Known:• It is already known that endurance training
has a positive effect on depressive symptoms.\r\n \r\n
\ \r\n What
is New:• A relevant proportion of adolescents with major
depressive disorder do not achieve their V̇O2max during a graded cardiopulmonary
exercise test.• Adolescents with major depressive disorder
have significantly lower cardiorespiratory fitness compared to sex- and age-related
control values.\r\n \r\n

text: Abstract In this work, we report on an improved cell assembly of cylindrical
electrochemical cells for 23Na in-situ solid-state NMR (ssNMR) investigations.
The cell set-up is suitable for using powder electrode materials. Reproducibility
of our cell assembly is analyzed by preparing two cells containing hard carbon
(HC) powder as working electrode and sodium metal as reference electrode. Electrochemical
storage properties of HC powder electrode derived from carbonization of sustainable
cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation
of a Na{\textbar}NaPF6{\textbar}HC cell (cell 1) over a period of 22?days, showing
high cell stability. After the galvanostatic process, the HC powder material is
investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium
species in different chemical environments is obtained. Subsequently, a second
Na{\textbar}NaPF6{\textbar}HC cell (cell 2) is sodiated for 11?days achieving
a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material
extracted from this cell clearly indicate the presence of quasi-metallic sodium
species next to ionic sodium species. This observation of quasi-metallic sodium
species is discussed in terms of the achieved capacity of the cell as well as
of side reactions of sodium in this electrode material.

text: AbstractThe biexciton‐exciton emission cascade
commonly used in quantum‐dot systems to generate polarization entanglement yields
photons with intrinsically limited indistinguishability. In the present work,
it focuses on the generation of pairs of photons with high degrees of polarization
entanglement and simultaneously high indistinguishability. It achieves this goal
by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates
that a suitably tailored circular Bragg reflector fulfills the requirements of
sufficient selective Purcell enhancement of biexciton emission paired with spectrally
broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical
study combines (i) the optimization of realistic photonic structures solving Maxwell's
equations from which model parameters are extracted as input for (ii) microscopic
simulations of quantum‐dot cavity excitation dynamics with full access to photon
properties. It reports non‐trivial dependencies on system parameters and use the
predictive power of the combined theoretical approach to determine the optimal
range of Purcell enhancement that maximizes indistinguishability and entanglement
to near unity values, here specifically for the telecom C‐band at 1550 nm.
