text: "In this proceeding we consider a translation invariant Nelson type model
in\r\ntwo spatial dimensions modeling a scalar relativistic particle in interaction\r\nwith
a massive radiation field. As is well-known, the corresponding Hamiltonian\r\ncan
be defined with the help of an energy renormalization. First, we review a\r\nFeynman-Kac
formula for the semigroup generated by this Hamiltonian proven by\r\nthe authors
in a recent preprint (where several matter particles and exterior\r\npotentials
are treated as well). After that, we employ a few technical key\r\nrelations and
estimates obtained in our preprint to present an otherwise\r\nself-contained derivation
of new Feynman-Kac formulas for the fiber\r\nHamiltonians attached to fixed total
momenta of the translation invariant\r\nsystem. We conclude by inferring an alternative
derivation of the Feynman-Kac\r\nformula for the full translation invariant Hamiltonian."

text: We prove absence of ground states in the infrared-divergent spin boson model
at large coupling. Our key argument reduces the proof to verifying long range
order in the dual one-dimensional continuum Ising model, i.e., to showing that
the respective two point function is lower bounded by a strictly positive constant.
We can then use known results from percolation theory to establish long range
order at large coupling. Combined with the known existence of ground states at
small coupling, our result proves that the spin boson model undergoes a phase
transition with respect to the coupling strength. We also present an expansion
for the vacuum overlap of the spin boson ground state in terms of the Ising $n$-point
functions, which implies that the phase transition is unique, i.e., that there
is a critical coupling constant below which a ground state exists and above which
none can exist.

text: We study the ultraviolet problem for models of a finite-dimensional quantum
mechanical system linearly coupled to a bosonic quantum field, such as the (many-)spin
boson model or its rotating-wave approximation. If the state change of the system
upon emission or absorption of a boson is either given by a normal matrix or by
a 2-nilpotent one, which is the case for the previously named examples, we prove
an optimal renormalization result. We complement it, by proving the norm resolvent
convergence of appropriately regularized models to the renormalized one. Our method
consists of a dressing transformation argument in the normal case and an appropriate
interior boundary condition for the 2-nilpotent case.

text: In this short communication we discuss the ultraviolet renormalization of
the van Hove-Miyatake scalar field, generated by any distributional source. An
abstract algebraic approach, based on the study of a special class of ground states
of the van Hove-Miyatake dynamical map is compared with an Hamiltonian renormalization
that makes use of a non-unitary dressing transformation. The two approaches are
proved to yield equivalent results.

text: In this paper we construct the non-trivial, renormalized Hamiltonian for a
class of spin-boson models with supercritical form factors, including the one
describing the Weisskopf-Wigner spontaneous emission. The renormalization is performed
through both a self-energy and mass renormalization, in the so-called Hamiltonian
formalism of constructive quantum field theory, implemented by a non-unitary dressing
transformation. This solves the problem of triviality for unitarily-renormalized
supercritical spin-boson models.

case of step-coin quantum walks with two-dimensional coin space, we recover the
same convergence rate for the supremum distance and prove optimality.

text: We propose a definition of Coxeter-Dynkin algebras of canonical type generalising
the definition as a path algebra of a quiver. Moreover, we construct two tilting
objects over the squid algebra - one via generalised APR-tilting and one via one-point-extensions
and reflection functors - and identify their endomorphism algebras with the Coxeter-Dynkin
algebra. This shows that our definition gives another representative in the derived
equivalence class of the squid algebra, and hence of the corresponding canonical
algebra. Finally, we have a closer look at the Grothendieck group and the Euler
form which illustrates the connection to Saito's classification of marked extended
affine root systems. On the other hand, this enables us to prove that in the domestic
case Coxeter-Dynkin algebras are of finite representation type.

text: We introduce a new class of reflection groups associated with the canonical
bilinear lattices of Lenzing, which we call reflection groups of canonical type.
The main result of this work is a categorification of the corresponding poset
of non-crossing partitions for any such group, realized via the poset of thick
subcategories of the category of coherent sheaves on an exceptional hereditary
curve generated by an exceptional sequence. A second principal result, essential
for the categorification, is a proof of the transitivity of the Hurwitz action
in these reflection groups.

text: "\r\n Objectives\r\n
\ To date, consistent evidence for consequences of heading
in football (soccer) on the structure and function of the brain is lacking, but
first studies indicate a potential effect of specific high-magnitude headers.
The purpose of this longitudinal, prospective study was to investigate whether
potential structural and/or functional alterations within the brain were associated
with (high-magnitude) heading.\r\n \r\n \r\n
\ Methods\r\n 3T
MRI sequences were obtained from active high-level male players before and after
an observation period of 17.2 months (median). Cortical thickness and grey matter
(GM) volume were investigated on a whole-brain level. Functional connectivity
(FC) was analysed in the default mode network (DMN) and salience network (SN).
During the observation period, each training and each match was videotaped and
evaluated regarding the heading exposure. Significant structural and functional
findings were subsequently correlated with specific header characteristics.\r\n
\ \r\n \r\n Results\r\n
\ 14 included participants (mean age: 20.36±3.34 years)
played 5822 headers. GM volume remained unchanged, whereas cortical thickness
decreased minimally from pre-measurement to post-measurement in a left precentral
region (mean change: 0.048±0.128 mm; clusterwise p=0.0416). Within the SN, FC
increased in one cluster (false discovery rate corrected p=0.026). FC remained
stable within the DMN and between DMN and SN. Change from pre-measurement to post-measurement
for the significant results did not correlate with heading variables.\r\n
\ \r\n \r\n Conclusion\r\n
\ Our findings may indicate no cumulative effect of
heading during the observation period. As these results contrast with cross-sectional
findings, more longitudinal, prospective studies with a greater sample size are
urgently needed to understand potential heading effects.\r\n "

text: Porous carbons are prominent electrode materials in energy storage applications
such as supercapacitors. However, rational materials development is hampered by
difficulties in interpreting electrochemical impedance spectra (EIS) and drawing
conclusions about promising aspects of device improvement. Here, we characterized
electrodes consisting of activated carbon with polyacrylic acid binder in four
different concentrations of sulfuric acid, using cyclic voltammetry and electrochemical
impedance spectroscopy. Both datasets were evaluated with simple equivalent circuits
and comparatively analyzed. Conductivity of the electrolyte was independently
measured. Cyclic voltammograms (CV) show larger resistance and capacitance at
low scan rates. Resistances obtained from EIS are in good agreement with those
obtained by cyclic voltammograms particularly at high scan rates. The comparison
against specific electrolyte resistance can reveal whether resistances within
the solid electrode architecture or resistances within the electrolyte, partially
confined by pores, are the dominant cause of increased resistance at low scan
rate. Comparison between CV and EIS points to the main electrode capacitance being
described by a constant phase element (CPE) used to fit the low-frequency region
of EIS.

text: Adiabatic demagnetization refrigeration (ADR) is regaining relevance
for refrigeration to temperatures below 1 K as global helium-3 supply is increasingly
strained. While ADR at these temperatures is long established with paramagnetic
hydrated salts, more recently, frustrated rare-earth oxides were found to offer
higher entropy densities and practical advantages, since they do not degrade under
heating or evacuation. We report structural, magnetic, and thermodynamic properties
of the rare-earth borates Ba3XB9O18 and Ba3XB3O9 with X = (Yb, Gd). Except for
Ba3GdB9O18, which orders at 108 mK, the three other materials remain paramagnetic
down to their lowest measured temperatures. ADR performance starting at 2 K in
a field of 5 T is analyzed and compared to literature.
