description: Random heteropolymers are a minimal description of biopolymers and can provide a theoretical framework to the investigate the formation of loops in biophysical experiments. A two--state model provides a consistent and robust way to study the scaling properties of loop formation in polymers of the size of typical biological systems. Combining it with self--adjusting simulated--tempering simulations, we can calculate numerically the looping properties of several realizations of the random interactions within the chain. Differently from homopolymers, random heteropolymers display at different temperatures a continuous set of scaling exponents. The necessity of using self--averaging quantities makes finite--size effects dominant at low temperatures even for long polymers, shadowing the length--independent character of looping probability expected in analogy with homopolymeric globules. This could provide a simple explanation for the small scaling exponents found in experiments, for example in chromosome folding.
Quantum Correlations of Ideal Bose and Fermi Gases in the Canonical Ensemble

description: We derive an expression for the reduced density matrices of ideal Bose and Fermi gases in the canonical ensemble, which corresponds to the Bloch--De Dominicis (or Wick's) theorem in the grand canonical ensemble for normal-ordered products of operators. Using this expression, we study one- and two-body correlations of homogeneous ideal gases with $N$ particles. The pair distribution function $g^{(2)}(r)$ of fermions clearly exhibits antibunching with $g^{(2)}(0)=0$ due to the Pauli exclusion principle at all temperatures, whereas that of normal bosons shows bunching with $g^{(2)}(0)\approx 2$, corresponding to the Hanbury Brown--Twiss effect. For bosons below the Bose--Einstein condensation temperature $T_0$, an off-diagonal long-range order develops in the one-particle density matrix to reach $g^{(1)}(r)=1$ at $T=0$, and the pair correlation starts to decrease towards $g^{(2)}(r)\approx 1$ at $T=0$. The results for $N\rightarrow \infty$ are seen to converge to those of the grand canonical ensemble obtained by assuming the average $\langle\hatψ({\bf r})\rangle$ of the field operator $\hatψ({\bf r})$ below $T_0$. This fact justifies the introduction of the "anomalous" average $\langle\hatψ({\bf r})\rangle\neq 0$ below $T_0$ in the grand canonical ensemble as a mathematical means of removing unphysical particle-number fluctuations to reproduce the canonical results in the thermodynamic limit.

description: In this work, we study linearised gravitational fields on the entire Minkowski space-time including space-like infinity. The generalised conformal field equations linearised about a Minkowski background are utilised for this purpose. In principle, this conformal representation of Einstein's equations can be used to carry out global simulations of Minkowski space-time. We investigate thoroughly this possibility.

description: Let $H$ be either a complex inner product space of dimension at least two, or a real inner product space of dimension at least three. Let us fix an $α\in \left(0,\tfracπ{2}\right)$. The purpose of this paper is to characterize all bijective transformations on the projective space $P(H)$ obtained from $H$ which preserves the angle $α$ between lines in both directions. (We emphasize that we do not assume anything about other angles). For real inner product spaces and when $H=\mathbb{C}^2$ we do this for every $α$, and when $H$ is a complex inner product space of dimension at least three we describe the structure of these transformations for $α\leq\tfracπ{4}$. As an application, we give an Uhlhorn-type generalization of a famous theorem of Wigner which is considered to be a cornerstone of the mathematical foundations of quantum mechanics. Namely, we show that under the above assumptions, every bijective map on the set of pure states of a quantum mechanical system that preserves the transition probability $\cos^2α$ in both directions is a Wigner symmetry (i.e. it automatically preserves all transition probability), except for the case when $H=\mathbb{C}^2$ and $α= \tfracπ{4}$ where an additional possibility occurs. We note that the classical theorem of Uhlhorn is the solution for the $α= \tfracπ{2}$ case. Usually in the literature, results which are connected to Wigner's theorem are discussed under the assumption of completeness of $H$, however, here we shall remove this unnecessary hypothesis. Our main tools are a characterization of bijective maps on unit spheres of real inner product spaces which preserve an angle in both directions, and an extension of Uhlhorn's theorem for non-complete inner product spaces.

description: The goal of the present study is to extend our current knowledge of the diffuse radio source (halo and relic) populations to $z$ $>$ 0.3. Here we report GMRT and EVLA radio observations of six galaxy clusters taken from the MAssive Cluster Survey (MACS) catalogue to detect diffuse radio emission. We used archival GMRT (150, 235 and 610 MHz) and EVLA (L band) data and made images at multiple radio frequencies of the following six clusters - MACSJ0417.5-1154, MACSJ1131.8-1955, MACSJ0308.9+2645, MACSJ2243.3-0935, MACSJ2228.5+2036 and MACSJ0358.8-2955. We detect diffuse radio emission (halo or relic or both) in the first four clusters. In the last two clusters we do not detect any diffuse radio emission but we put stringent upper-limits on their radio powers. We also use archival {\it Chandra} X-ray data to carry out morphology and substructure analysis of these clusters. We find that based on X-ray data, these MACS clusters are non-relaxed and show substructures in their temperature distribution. The radio powers of the first four MACS clusters are consistent with their expected values in the $L_{x}$--$P_{1.4GHz}$ plot. {However, we found ultra-steep spectrum radio halo in the MACSJ0417.5-1154 cluster whose rest-frame cut-off frequency is at $\sim$ 900 MHz}. The remaining two clusters whose radio powers are $\sim$ 11 times below the expected values are most likely to be in the `off-state' as has been postulated in some of the models of radio halo formation.

Gridless DOA Estimation with Multiple Frequencies

description: Direction-of-arrival (DOA) estimation is widely applied in acoustic source localization. A multi-frequency model is suitable for characterizing the broadband structure in acoustic signals. In this paper, the continuous (gridless) DOA estimation problem with multiple frequencies is considered. This problem is formulated as an atomic norm minimization (ANM) problem. The ANM problem is equivalent to a semi-definite program (SDP) which can be solved by an off-the-shelf SDP solver. The dual certificate condition is provided to certify the optimality of the SDP solution so that the sources can be localized by finding the roots of a polynomial. We also construct the dual polynomial to satisfy the dual certificate condition and show that such a construction exists when the source amplitude has a uniform magnitude. In multi-frequency ANM, spatial aliasing of DOAs at higher frequencies can cause challenges. We discuss this issue extensively and propose a robust solution to combat aliasing. Numerical results support our theoretical findings and demonstrate the effectiveness of the proposed method.

description: We study the time-dependence of Hawking radiation for a black hole in the Unruh vacuum, and find that it is not robust against certain UV and IR effects. If there is a UV cutoff at the Planck scale, Hawking radiation is turned off after the scrambling time. In the absence of a UV cutoff, Hawking radiation is sensitive to the IR cutoff through a UV/IR connection due to higher-derivative interactions in the effective theory. Furthermore, higher-derivative interactions with the background contribute to a large amplitude of particle creation that changes Hawking radiation. This unexpected large effect is related to a peculiar feature of the Hawking particle wave packets.

description: We show that switching in ferroelectric lead germanate and lead iron tantalate zirconate titanate (PZTFT) does not resemble the equilibrium domain structure evolution of the Landau-Lifshitz-Kittel model but is instead highly nonequilibrium and similar, respectively, to the Richtmyer-Meshkov instability in liquids and the Helfrich-Hursault sliding instability in liquid crystals. The resulting nano-domain structures in PZTFT are circular or parabolic and involving folding bifurcations. These may have an undesirable impact on ferroelectric thin-film memoriesthat are also ferroelastic.

description: Model-independent search strategies have been increasingly proposed in recent years because on the one hand there has been no clear signal for new physics and on the other hand there is a lack of a highly probable and parameter-free extension of the standard model. For these reasons, there is no simple search target so far. In this work, we try to take a new direction and ask the question: bearing in mind that we have a large number of new physics theories that go beyond the Standard Model and may contain a grain of truth, can we improve our search strategy for unknown signals by using them "in combination"? In particular, we show that a signal hypothesis based on a large, intermingled set of many different theoretical signal models can be a superior approach to find an unknown BSM signal. Applied to a recent data challenge, we show that "mixture-of-theories training" outperforms strategies that optimize signal regions with a single BSM model as well as most unsupervised strategies. Applications of this work include anomaly detection and the definition of signal regions in the search for signals of new physics.

description: While macroscopic properties of spin glasses have been thoroughly investigated, their manifestation in the corresponding microscopic configurations is much less understood. Cases where both descriptions have been provided, such as constraint satisfaction problems, are limited to their ground state properties. To identify the emerging microscopic structures with macroscopic phases at different temperatures, we study the $p$-spin model with $p\!=\!3$. We investigate the properties of self-sustained clusters, defined as variable sets where in-cluster induced fields dominate over the field induced by out-cluster spins, giving rise to stable configurations with respect to fluctuations. We compute the entropy of self-sustained clusters as a function of temperature and their sizes. In-cluster fields properties and the difference between in-cluster and out-cluster fields support the observation of slow-evolving spins in spin models. The findings are corroborated by observations in finite dimensional lattices at low temperatures.

description: The Raman 2D line of graphene is widely used for device characterization and during device fabrication as it contains valuable information on e.g. the direction and magnitude of mechanical strain and doping. Here we present systematic asymmetries in the 2D line shape of exfoliated graphene and graphene grown by chemical vapor deposition. Both graphene crystals are fully encapsulated in van der Waals heterostructures, where hexagonal boron nitride and tungsten diselenide are used as substrate materials. In both material stacks, we find very low doping values and extremely homogeneous strain distributions in the graphene crystal, which is a hall mark of the outstanding electronic quality of these samples. By fitting double Lorentzian functions to the spectra to account for the contributions of inner and outer processes to the 2D peak, we find that the splitting of the sub-peaks, $6.6 \pm 0.5$ cm$^{-1}$(hBN-Gr-WSe2) and $8.9 \pm 1.0$ cm$^{-1}$ (hBN-Gr-hBN), is significantly lower than the values reported in previous studies on suspended graphene.

description: In recent years there has been great interest in using deep neural networks (DNN) for super-resolution image reconstruction including for structured illumination microscopy (SIM). While these methods have shown very promising results, they all rely on data-driven, supervised training strategies that need a large number of ground truth images, which is experimentally difficult to realize. For SIM imaging, there exists a need for a flexible, general, and open-source reconstruction method that can be readily adapted to different forms of structured illumination. We demonstrate that we can combine a deep neural network with the forward model of the structured illumination process to reconstruct sub-diffraction images without training data. The resulting physics-informed neural network (PINN) can be optimized on a single set of diffraction limited sub-images and thus doesn't require any training set. We show with simulated and experimental data that this PINN can be applied to a wide variety of SIM methods by simply changing the known illumination patterns used in the loss function and can achieve resolution improvements that match well with theoretical expectations.

description: We report the detection of stellar eclipses in the LP 661-13 system. We present the discovery and characterization of this system, including high resolution spectroscopic radial velocities and a photometric solution spanning two observing seasons. LP 661-13 is a low mass binary system with an orbital period of $4.7043512^{+0.0000013}_{-0.0000010}$ days at a distance of $24.9 \pm 1.3$ parsecs. LP 661-13A is a $0.30795 \pm 0.00084$ $M_\odot$ star while LP 661-13B is a $0.19400 \pm 0.00034$ $M_\odot$ star. The radius of each component is $0.3226 \pm 0.0033$ $R_\odot$ and $0.2174 \pm 0.0023$ $R_\odot$, respectively. We detect out of eclipse modulations at a period slightly shorter than the orbital period, implying that at least one of the components is not rotating synchronously. We find that each component is slightly inflated compared to stellar models, and that this cannot be reconciled through age or metallicity effects. As a nearby eclipsing binary system where both components are near or below the full-convection limit, LP 661-13 will be a valuable test of models for the structure of cool dwarf stars.

description: Introdução: A pandemia de COVID-19 teve um impacto significativo na saúde mental dos enfermeiros que trabalham em contexto hospitalar. Estes profissionais, enfrentaram uma série de desafios psicológicos, incluindo stress, ansiedade, burnout, depressão e sintomas de transtornos de saúde mental, pelo fato de estarem expostos ao risco de contrair a doença, bem como ao stress emocional causado por cuidar de pacientes graves e lidar com a morte. Além disso, muitos enfermeiros confrontaram-se com o impacto da fadiga, do horário de trabalho prolongado e da sobrecarga de trabalho, o que contribuiu para o aumento do stress e da ansiedade. A falta de equipamento de proteção adequado e recursos financeiros, bem como a sobrecarga de trabalho, a falta de suporte emocional e de recursos psicológicos também influenciaram negativamente a saúde mental dos enfermeiros. Objetivo: Analisar o impacto que a pandemia de COVID-19 teve na ansiedade dos enfermeiros trabalhando em contexto hospitalar. Metodologia: Revisão integrativa da literatura que utilizou a mnemónica PICO para compilar a pergunta de investigação. Procedeu-se à pesquisa de artigos na plataforma EBSCOhost, selecionando-se artigos publicados entre janeiro de 2010 e dezembro de 2022 nas bases de dados MEDLINE complete e CINAHL complete. Foram selecionados seis artigos e seguiram-se as recomendações do método Preferred Reporting Items for Systematic Reviews and Meta-Analyses – PRISMA. Resultados: a pandemia de COVID-19 teve um impacto significativo na ansiedade dos enfermeiros em contexto hospitalar. A exposição ao risco de contrair a doença, o stress emocional causado por cuidar de doentes graves e lidar com a morte, bem como a falta de equipamento de proteção adequado, foram fatores que contribuíram para aumentar a ansiedade dos enfermeiros. Foram também observadas variações no impacto da pandemia na ansiedade dos enfermeiros, dependendo de variáveis biológicas e sociodemográficas, como idade, género, estado civil e nível de stress prévio. Os anos de serviço na profissão e o nível de satisfação com o trabalho foram também fatores preditores. Conclusão: Destacou-se a necessidade de se fornecer suporte e recursos aos enfermeiros durante a pandemia, a fim de mitigar seu impacto na ansiedade e na saúde mental. É importante considerar as variáveis biológicas e sociodemográficas ao planear medidas de apoio, a fim de atender às necessidades específicas de cada enfermeiro.

description: The central role played by pseudodifferential operators in relativistic dynamics is very well know. In this work, operators as the Schrodinger one (e.g: square root) are treated from the point of view of the non-local pseudodifferential Green functions. Starting from the explicit construction of the Green (semigroup) theoretical kernel, a theorem linking the integrability conditions and their dependence on the spacetime dimensions is given. Relativistic wave equations with arbitrary spin and the causality problem are discussed with the algebraic interpretation of the radical operator and their relation with coherent and squeezed states. Also we perform by mean of pure theoretical procedures (based in physical concepts and symmetry) the relativistic position operator which satisfies the conditions of integrability : it is non-local, Lorentz invariant and does not have the same problems as the "local"position operator proposed by Newton and Wigner. Physical examples, as Zitterbewegung and rogue waves, are presented and deeply analysed in this theoretical framework.

description: We experimentally and theoretically investigate mechanical nanooscillators coupled to the light in an optical ring resonator made of dielectric mirrors. We identify an optomechanical damping mechanism that is fundamentally different to the well known cooling in standing wave cavities. While, in a standing wave cavity the mechanical oscillation shifts the resonance frequency of the cavity in a ring resonator the frequency does not change. Instead the position of the nodes is shifted with the mechanical excursion. We derive the damping rates and test the results experimentally with a silicon-nitride nanomembrane. It turns out that scattering from small imperfections of the dielectric mirror coatings has to be taken into account to explain the value of the measured damping rate. We extend our theoretical model and regard a second reflector in the cavity that captures the effects of mirror back scattering. This model can be used to also describe the situation of two membranes that both interact with the cavity fields. This may be interesting for future work on synchronization of distant oscillators that are coupled by intracavity light fields.

description: In distributed detection systems, energy-efficient ordered transmission (EEOT) schemes are able to reduce the number of transmissions required to make a final decision. In this work, we investigate the effect of data falsification attacks on the performance of EEOT-based systems. We derive the probability of error for an EEOT-based system under attack and find an upper bound (UB) on the expected number of transmissions required to make the final decision. Moreover, we tighten this UB by solving an optimization problem via integer programming (IP). We also obtain the FC's optimal threshold which guarantees the optimal detection performance of the EEOT-based system. Numerical and simulation results indicate that it is possible to reduce transmissions while still ensuring the quality of the decision with an appropriately designed threshold.

Maps of crystal orientations, domain configurations, symmetry breaking are obtained using scanning convergent beam electron diffraction (SCBED). Such measurements suggest the merging of 2D and 1D topological defects, with implications for domain-switching mechanisms in relaxor ferroelectric crystals, and the possibility of a new form of nanoscale ferroelectric devices.

description: A superconducting radio-frequency (SRF) photo injector is in operation at the electron linac for beams with high brilliance and low emittance (ELBE) radiation center and generates continuous wave (CW) electron beams with high average current and high brightness for user operation since 2018. The speed of emittance measurement at the SRF gun beamline can be increased by improving the slit-scan system, thus the measurement time for one phase space mapping can be shortened from about 15 minutes to 90 seconds. A parallel algorithm and machine learning have been used to reduce the beamlet image noise. In order to estimate the uncertainty in the calculation of normalized emittance, we analyze the main error contributions such as slit position uncertainty, image noise, space charge effects and energy measurement inaccuracy.

description: Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star-formation activity and mass growth. Merger systems have commonly been identified from their disturbed morphologies, and we now can employ Integral Field Spectroscopy to detect and analyze the impact of mergers on stellar kinematics as well. We visually classified galaxy morphology using deep images ($μ_{\rm r} = 28\,\rm mag\,\, arcsec^{-2}$) taken by the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory. In this paper we investigate 63 bright ($M_{\rm r}

description: Among the early B-type stars, He-rich Bp stars exhibit the strongest large-scale organized magnetic fields with a predominant dipole contribution. The presence of $β$ Cep-like pulsations in the typical magnetic early Bp-type star HD 96446 was announced a few years ago, but the analysis of the magnetic field geometry was hampered by the absence of a reliable rotation period and a sophisticated procedure for accounting for the impact of pulsations on the magnetic field measurements. Using new spectropolarimetric observations and a recently determined rotation period based on an extensive spectroscopic time series, we investigate the magnetic field model parameters of this star under more detailed considerations of the pulsation behaviour of the line profiles.
Market Microstructure During Financial Crisis: Dynamics of Informed and Heuristic-Driven Trading

description: We implement a market microstructure model including informed, uninformed and heuristic-driven investors, which latter behave in line with loss-aversion and mental accounting. We show that the probability of informed trading (PIN) varies significantly during 2008. In contrast, the probability of heuristic-driven trading (PH) remains constant both before and after the collapse of Lehman Brothers. Cross-sectional analysis yields that, unlike PIN, PH is not sensitive to size and volume effects. We show that heuristic-driven traders are universally present in all market segments and their presence is constant over time. Furthermore, we find that heuristic-driven investors and informed traders are disjoint sets.

description: Introdução: As lesões por pressão (LP) são um grande problema de saúde pública, pois diminuem significativamente a qualidade de vida das pessoas e, por outro lado, aumentam os custos e os encargos nos serviços de saúde. As intervenções de enfermagem são fundamentais de forma a atuar na sua prevenção através da implementação de estratégias para diminuir todos estes impactos negativos. É importante que os profissionais de saúde, indivíduos e cuidadores estejam consciencializados do papel que a nutrição tem na saúde, uma vez que a mesma é essencial para providenciar energia suficiente para suportar o crescimento tecidular e posterior cicatrização. Objetivo: Identificar os benefícios da terapia nutricional à pessoa na promoção da cicatrização de LP. Metodologia: A metodologia utilizada alicerçou-se numa revisão sistemática da literatura, que incluiu o desenvolvimento da pergunta de investigação, a pesquisa em bases de dados científicos, a análise e a interpretação dos artigos selecionados bem como a síntese e apresentação dos resultados obtidos. Para a seleção de artigos e formulação da pergunta de investigação utilizou-se a metodologia PICO. Resultados: Aplicada a metodologia, obteve-se um conjunto final de 9 artigos selecionados, os quais sugerem existir evidência científica de que uma terapia de nutrição adequada é essencial para a cicatrização de feridas. Conclusão: Com base na evidência científica, a terapia de nutrição adequada às pessoas com feridas crónicas parece contribuir para uma melhor cicatrização, bem como para uma diminuição dos custos em saúde. Suposições sobre a contribuição da enfermagem para o cuidado, devem ser substituídas por evidências empíricas acerca das contribuições reais da profissão de enfermagem para o cuidado e, a prevenção de feridas crónicas, é um imprescindível indicador da qualidade dos cuidados prestados.

description: It is of great importance to develop a photodetector system with an ultralow radioactivity background in rare event searches. Silicon photomultipliers (SiPMs) and application-specific integrated circuits (ASICs) are two ideal candidates for low background photosensors and readout electronics, respectively, because they are mainly composed of silicon, which can achieve good radio-purity without considerable extra effort. However, interposers, used to provide mechanical support and signal routes between the photosensor and the electronics, are a bottleneck in building ultralow background photodetectors. Silicon and quartz are two candidates to construct the low background interposer because of their good radio-purity; nevertheless, it is non-trivial to produce through silicon vias (TSV) or through quartz vias (TQV) on the large area silicon or quartz wafer. In this work, based on double-sided TSV interconnect technology, we developed the first prototype of a silicon interposer with a size of 10~cm$\times$10~cm and a thickness of 320~$μ$m. The electrical properties of the interposer are carefully evaluated at room temperature, and its performance is also examined at -110~$^\circ$C with an integrated SiPM on the interposer. The testing results reveal quite promising performance of the prototype, and the single photoelectron signals can be clearly observed from the SiPM. The features of the observed signals are comparable with those from the SiPM mounted on a normal FR4-based PCB. Based on the success of the silicon interposer prototype, we started the follow-up studies that aimed to further improve the performance and yield of the silicon interposer, and eventually to provide a solution for building an ultralow background photodetector system.

Der Strafantrag gegenüber der Polizei im elektronischen Rechtsverkehr

description: Die Einreichung des Strafantrages nach § 77 StGB i. V. m § 158 Abs. 2 Hs. 2 StPO gegenüber der Polizei abseits des klassischen Briefverkehrs führt regelmäßig zur für den vermeintlichen Antragssteller unerwünschten Unwirksamkeit des betreffenden Antrages. Denn das Schriftlichkeitserfordernis des § 158 Abs. 2 Hs. 2 StPO ist zwar einerseits kein besonders strenges, orientiert sich nicht etwa strikt an § 126 BGB. Andererseits hat sich in der Rechtsprechung eine solche Vielzahl von Einzelfällen herausgebildet, die mal unzulässig, mal zulässig sind, dass für den juristischen Laien kaum noch erkennbar ist, wann ein Strafantrag wirksam gestellt wurde, wenn er nicht formstreng als unterschriebener Antrag per Post oder direkt auf der Polizeiwache eingereicht wurde. Auf dem Gebiet des elektronischen Rechtsverkehrs hat der Gesetzgeber in dieser Hinsicht zwar Klarheit geschaffen. Denn § 32 a StPO macht eindeutige Vorgaben, wie Rechtsmittel per elektronischer Kommunikation eingereicht werden können. Doch führt dies entgegen der eigentlichen Intention des Gesetzgebers dazu, dass der Bürger im Rahmen der Strafantragsstellung faktisch überhaupt nicht mehr am elektronischen Rechtsverkehr teilnimmt. Dem Umgang mit dieser Problematik widmet sich dieser Artikel.

description: Ending preventable maternal and neonatal morbidity and mortality cannot be achieved without quality care intervention during the perinatal period. Ethiopia is one of the countries facing challenges in averting maternal and neonatal mortality. Despite different quality care initiatives targeting maternal health in Ethiopia, the quality of care has been questioned, and there has been a scoping review in this area. The current review identifies, maps, and summarises the effectiveness of maternal and newborn quality improvement interventions in Ethiopia.

description: Constraining the inflationary epoch is one of the aims of modern cosmology. In order to fully exploit current and future small-scale observations, it is necessary to devise tools to directly relate them to the early universes dynamics. We present here a novel reverse engineer approach able to connect fundamental late-time observables to consistent inflationary dynamics and, eventually, to the inflaton potential. Employing this procedure, we are able to describe which conditions can give rise to a raised plateau in the power spectrum of curvature perturbations at small scales, which are not constrained by CMB observations. Within this new phenomenologically-driven approach, we find that inflation can generate a raised plateau in the spectrum of curvature perturbations that potentially connects three fundamental observables: a dominant component of the dark matter in the form of asteroid-mass/atomic-size primordial black holes; detectable signals in stochastic gravitational waves and a subdominant fraction of stellar-mass primordial black holes mergers.
