Methoden In einer retrospektiven Analyse wurde die Umsetzung der klinikinternen Handlungsanweisung zur Ernährung kritisch kranker Patienten (Gültigkeitszeitraum September 2013 bis Januar 2016) sowie der Anordnung zur Ernährungstherapie auf einer operativen Intensivstation des Universitätsklinikums Bonn an Daten des Ernährungsmanagements von 31 Langzeit-Intensivpatienten (7 Frauen; Alter: 60 ± 17 Jahre; BMI: 28 ± 10 kg/m2; Dauer des Intensivaufenthalts: 34 ± 16 Tage) evaluiert. Ausgewertet wurden Daten zur Initiation, zum Ablauf sowie zur Berechnung und Umsetzung der Energie- und Proteinzufuhr. Dazu wurden jeweils die im Stationsalltag angeordnete bzw. protokollierte Zufuhr, die protokollierte Zufuhr abzüglich Reflux sowie das retrospektiv beurteilte Ziel, welches durch die klinikinterne Handlungsanweisung indiziert war, miteinander verglichen (linear gemischtes Modell). Ergebnisse Mit der enteralen Ernährung wurde im Mittel an Tag 4 ± 3, mit der (supplementierenden) parenteralen an Tag 3 ± 3 begonnen. Die Energiezufuhr wurde mit Korrekturfaktoren als ein Vielfaches des Grundumsatzes nach Harris & Benedict berechnet. Der individuell verwendete Korrekturfaktor zur Berechnung der angeordneten Energiezufuhr wich über die gesamte Dauer des stationären Aufenthalts 0,1 ± 0,3 vom retrospektiv als angemessen erachteten Korrekturfaktor ab. Hieraus resultierte eine Abweichung der angeordneten Energiezufuhr vom Energieziel von 123 ± 528 kcal/24 h. Insbesondere in den Tagen 1 – 10 betrug die Abweichung des angeordneten vom retrospektiv als angemessen erachteten Korrekturfaktor 0,2 ± 0,4, was zu einer Differenz zwischen angeordneter Energiezufuhr und Energieziel von 426 ± 772 kcal/24 h führte. Die protokollierte Proteinzufuhr lag über die gesamte Behandlungsdauer bei 1,1 g/kg KG/24 h, während das retrospektiv ermittelte Proteinziel 1,0 g/kg KG/24 h betrug. Schlussfolgerung Die Analyse liefert vertrauenswürdige Daten zur Implementation einer individualisierten Ernährungstherapie von Langzeit-Intensivpatienten auf einer operativen Intensivstation; diese können zur Weiterentwicklung von entsprechenden Handlungsanweisungen genutzt werden. Defizite bestehen sowohl im zeitlichen Ablauf (zu später Beginn) als auch in der Anordnung der Energie-/Nährstoffzufuhr.

Second-harmonic (SH) microscopy allows for the noninvasive visualization and analysis of ferroelectric domain structures and walls. While the technique is well understood in bulk lithium niobate, SH microscopy in thin films is largely influenced by interfacial reflections and resonant enhancements, which depend on film thicknesses and substrate materials. We present a comprehensive analysis of SH microscopy in x-cut lithium niobate thin films, based on a full three-dimensional focus calculation and accounting for interface reflections. We show that the dominant signal in backreflection originates from a copropagating phase-matched process observed through reflections, rather than direct detection of the counterpropagating signal as in bulk samples. We simulate the SH signatures of domain structures by a simple model of the domain wall as an extensionless transition from a −χ(2) to a +χ(2) region. This allows us to explain the main observation of domain structures in the thin-film geometry, and, in particular, we show that the SH signal from thin poled films allows to unambiguously distinguish areas, which are completely or only partly inverted in depth.}}, author = {{Rüsing, Michael and Zhao, J. and Mookherjea, S.}}, issn = {{0021-8979}}, journal = {{Journal of Applied Physics}}, keywords = {{General Physics and Astronomy}}, number = {{11}}, publisher = {{AIP Publishing}}, title = {{{Second harmonic microscopy of poled x-cut thin film lithium niobate: Understanding the contrast mechanism}}}, doi = {{10.1063/1.5113727}}, volume = {{126}}, year = {{2019}}, } @article{47947, author = {{Rüsing, Michael and Weigel, Peter O. and Zhao, Jie and Mookherjea, Shayan}}, issn = {{1932-4510}}, journal = {{IEEE Nanotechnology Magazine}}, keywords = {{Electrical and Electronic Engineering, Mechanical Engineering}}, number = {{4}}, pages = {{18--33}}, publisher = {{Institute of Electrical and Electronics Engineers (IEEE)}}, title = {{{Toward 3D Integrated Photonics Including Lithium Niobate Thin Films: A Bridge Between Electronics, Radio Frequency, and Optical Technology}}}, doi = {{10.1109/mnano.2019.2916115}}, volume = {{13}}, year = {{2019}}, } @article{47946, author = {{Zhao, Jie and Rüsing, Michael and Mookherjea, Shayan}}, issn = {{1094-4087}}, journal = {{Optics Express}}, keywords = {{Atomic and Molecular Physics, and Optics}}, number = {{9}}, publisher = {{The Optical Society}}, title = {{{Optical diagnostic methods for monitoring the poling of thin-film lithium niobate waveguides}}}, doi = {{10.1364/oe.27.012025}}, volume = {{27}}, year = {{2019}}, } @article{47917, abstract = {{ Companies disclosing negative aspects in sustainability reports often employ legitimation strategies to present mishaps in a favorable light.

Even substantial legitimation (which reports on measures and behavioral change) mitigates the divestment decisions only if the company reports on concrete remediation actions in morally charged situations, such as social or environmental incidents.

The bandwidth for successful performance (increase of a score for a monetary competition) was manipulated to yield a success rate (positive feedback frequency) of approximately 50% adaptive to the current performance level. This allowed a variation of feedback valence unconfounded by success rate. In line with our hypotheses, the EEG data showed a valence‐dependent feedback‐related negativity (FRN) and a later fronto‐central component at the FCz electrode as well as a P300 component at the Pz electrode. Moreover, the P300 and amplitudes in the FRN time window reduced in the second half of practice but were still dependent on feedback valence. Behavioral adjustments were larger after feedback with negative valence and were predicted by the late fronto‐central component.
