description: In this letter, we propose to add dynamic frozen bits to underlying polar codes with a Reed-Muller information set with the aim of maintaining the same sub-decoding structure in Automorphism Ensemble (AE) and lowering the Maximum Likelihood (ML) bound by reducing the number of minimum weight codewords. We provide the dynamic freezing constraint matrix that remains identical after applying a permutation linear transformation. This feature also permits to drastically reduce the memory requirements of an AE decoder with polar-like codes having dynamic frozen bits. We show that, under AE decoding, the proposed dynamic freezing constraints lead to a gain of up to 0.25dB compared to the ML bound of the R(3,7) Reed-Muller code, at the cost of small increase in memory requirements.

description: Generalizing the concept of quantiles to the jump measure of a Lévy process, the generalized quantiles $q_τ^{\pm}>0$, for $τ>0$, are given by the smallest values such that a jump larger than $q_τ^{+}$ or a negative jump smaller than $-q_τ^{-}$, respectively, is expected only once in $1/τ$ time units. Nonparametric estimators of the generalized quantiles are constructed using either discrete observations of the process or using option prices in an exponential Lévy model of asset prices. In both models minimax convergence rates are shown. Applying Lepski's approach, we derive adaptive quantile estimators. The performance of the estimation method is illustrated in simulations and with real data.

description: Recently Csabai et al. have found a metagenomic sample set originally collected at Antarctica that most likely as a result of
 contamination contains traces of unique SARS-CoV-2 variants. Later on they identified putative host genomes. The preprints
 resulted a wide discussion in the news and social media and some comments on the preprint server or via private emails. Here
 we briefly reflect on some of them and present additional foreign sequences found in the same sample set.

description: 3-Morpholino-sydnonimine (SIN-1) is a NO-releasing compound which mimics the effects of cGMP through activation of soluble guanylyl cyclase. Its prodrug, molsidomine (SIN-10), does not release NO but does modulate various cell functions. These findings prompted us to study the effects of SIN-10 and SIN-1 on the respiratory burst in human neutrophils. SIN-10 was more effective than SIN-1 in inhibiting superoxide anion (O2-) formation induced by N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMet-Leu-Phe) and by C5a. The effects of SIN-1 and SIN-10 on O2- formation were additive or less than additive, indicating the sydnonimines acted through a common mechanism. The sydnonimines showed no effect on O2- formations induced by gamma-hexachlorocyclohexane, arachidonic acid and a phorbol ester. They did not inhibit O2- formation induced by xanthine oxidase, by autoxidation of pyrogallol and in a cell-free system from HL-60 leukemic cells. Neutrophils did not convert SIN-10 to SIN-1 as assessed by O2 consumption which accompanies NO release from SIN-1. The cell-permeant analogue of cGMP, N2,2'-O-dibutyryl guanosine 3':5'-monophosphate (Bt2cGMP), and SIN-10 but not SIN-1 inhibited fMet-Leu-Phe-induced O2 consumption. SIN-1 and SIN-10 slightly enhanced agonist binding to formyl peptide receptors, whereas Bt2cGMP was inhibitory. The sydnonimines did not affect GTP hydrolysis of heterotrimeric regulatory guanine nucleotide-binding proteins in HL-60 membranes. SIN-1 but not SIN-10 stimulated ADP-ribosylation of a 39-kDa protein in the cytosol of HL-60 cells. SIN-10 reduced fMet-Leu-Phe-induced rises in cytosolic Ca2+ concentration in neutrophils. These data suggest that SIN-10 inhibits the respiratory burst via a NO-independent mechanism which may involve inhibition of rises in cytosolic Ca2+ concentration.

description: Southwest France constitutes an interesting field to study the conditions and the forms of sea product consumption in early modern Western Europe because of its geographical situation. This area is widely open to the Bay of Biscay on the west and connected to the Mediterranean Sea by various roads and a canal from the east. The distances between certain interior parts of Southwest France and the Atlantic or Mediterranean coast were accentuated by bad transport conditions. Even in these inland areas, however , some sea products were consumed. In this paper, I would like to underline the complexity of this regional consumption of seafood, studying its modalities in the lit-toral areas and in the inland towns and countries. Such analysis takes into account the local fishery conditions, the forms of regional fresh and preserved sea product trade, the culinary seafood uses and the social implications of sea product consumption. Finally , differences between lower class and elite forms of sea product consumption prove as important as geographical contrasts.

description: We study definable sets $D$ of SU-rank 1 in $M^{eq}$, where $M$ is a countable homogeneous and simple structure in a language with finite relational vocabulary. Each such $D$ can be seen as a `canonically embedded structure', which inherits all relations on $D$ which are definable in $M^{eq}$, and has no other definable relations. Our results imply that if no relation symbol of the language of $M$ has arity higher than 2, then there is a close relationship between triviality of dependence and $D$ being a reduct of a binary random structure. Somewhat more preciely: (a) if for every $n \geq 2$, every $n$-type $p(x_1, ..., x_n)$ which is realized in $D$ is determined by its sub-2-types $q(x_i, x_j) \subseteq p$, then the algebraic closure restricted to $D$ is trivial; (b) if $M$ has trivial dependence, then $D$ is a reduct of a binary random structure.

description: The quantum statistics of atoms is typically observed in the behavior of an ensemble via macroscopic observables. However, quantum statistics modifies the behavior of even two particles, inducing remarkable consequences that are at the heart of quantum science. Here we demonstrate near-complete control over all the internal and external degrees of freedom of two laser-cooled 87Rb atoms trapped in two optical tweezers. This full controllability allows us to implement a massive-particle analog of a Hong-Ou-Mandel interferometer where atom tunneling plays the role of a photon beamsplitter. We use the interferometer to probe the effect of quantum statistics on the two-atom dynamics under tunable initial conditions, chosen to adjust the degree of atomic indistinguishability. Our work thereby establishes laser-cooled atoms in optical tweezers as a new route to bottom-up engineering of scalable, low-entropy quantum systems.

description: In vielen Großunternehmungen werden jährlich Millionen für Maßnahmen zur Verbesserung der Datenqualität (DQ) ausgegeben, wobei überwiegend in reaktive Datenqualitätsmaßnahmen (DQM) investiert wird (beispielsweise die Prüfung auf Adressfehler mit Hilfe von Assoziationsregeln). Hierbei werden oftmals die Größe einer existierenden Datenbasis und deren schlechte DQ als ausschlaggebende Kriterien für eine DQ-Investition angeführt. Sie lassen sich jedoch - so zeigen die Ergebnisse des Beitrags - nicht bestätigen. Vielmehr muss wegen der Charakteristik der reaktiven DQM beispielsweise je Datenattribut und Assoziationsregel entschieden werden, ob diese einen positiven Grenzbeitrag leisten. Entsteht ein solcher Beitrag nicht, so sind selbst bei einer großen, zu sichernden Datenmenge reaktive DQM nicht zu ergreifen. Daneben sind die heute noch stark vernachlässigten proaktiven DQM wegen ihres Multiplikatoreffekts den reaktiven DQM unter sonst gleichen Voraussetzungen sogar vorzuziehen. Proaktive DQM setzen unmittelbar bei der Datenerfassung an (zum Beispiel im Kundengespräch) und erlauben somit nach der Qualitätssicherung die Daten direkt wieder für eine bessere Beratung zu nutzen. Jedoch bergen DQM, insbesondere proaktive Maßnahmen, aufgrund ihrer speziellen, zeitverzögerten Wirkung die Gefahr einer Fehlinvestition. Große DQProjekte mit der in der Praxis oftmals genannten Zielsetzung schnell eine hohe Qualität realisieren zu wollen, sind unter diesem Aspekt nicht sinnvoll.
Possibility of Measuring spin precession of the nearest supermassive black hole by S stars

description: The supermassive black hole (SMBH) with 4 millions solar mass inside the radio-source Sgr A* in our Galactic center is the nearest SMBH. Once the S stars with shorter period are observed, the relativistic precessions especially the Lense-Thirring one can be measured by astronomical observations at 10 micro-arcsecond ($μ$as) level in future. An interesting but so far no attended problem is that the SMBH has not only spin but also spin precession like the other objects in the universe. In this paper, we study the effect of such spin precession on the orbital precessions of orbiting stars. Our results show that the spin precession can produce a periodic oscillation on the precession of the star's orbital plane, but no obvious effect on the periapse shift. For stars with $O(0.1)$yr period, such visible oscillations occur while the SMBH's spin-precession period is about from few tens of years to hundreds of years. And the period of oscillation is the same with the one of the spin precession. In principle, this oscillating orbital plane's precession can be observed and then the spin and spin precession of the nearest supermassive black hole can be determined.

Is the 126 GeV Higgs Boson Mass Calculable in Gauge-Higgs Unification?

description: We address a question whether the recently observed Higgs mass $M_{H} = 126$ GeV, of the order of the weak scale $M_{W}$, is calculable as a finite value in the scnenario of gauge-Higgs unification. In the scenario formulated on a flat 5-dimensional space-time, the Higgs mass is calculable, being protected under the quantum correction by gauge invariance, though the predicted Higgs mass is generally too small compared with $M_{W}$. In the 6-dimensional SU(3) model, however, a suitable orbifolding is known to lead to a mass of the order of $M_{W}$: $M_{H} = 2M_{W}$ at the tree level, which has some similarity to the corresponding prediction by the MSSM, $M_{H}$ leq (cos beta) $M_{Z}$. We demonstrate first by a general argument and secondly by explicit calculations that, even though the quantum correction to the quartic self-coupling of the Higgs field is UV-divergent, its deviation from that of $g^{2}$ is calculable, and therefore two observables, $M_{H}^{2}$ and Delta equiv $(M_{H}/2M_{W})^{2}-1$, are both calculable in the gauge-Higgs unification scenario. The implication of the precise value 126 GeV to the compactification scale and the bulk mass of the matter field in our model is also discussed.

description: Die Wasserversorger müssen den Nachweis erbringen, dass Kontaminationen wie pathogene Mikroorganismen, Toxine, Spurenstoffe und endokrine Disruptoren effektiv entfernt, zerstört oder inaktiviert werden und dass die bei ihren Aufbereitungsverfahren entstehenden Reaktionsprodukte gesundheitlich unbedenklich sind. Der Aufwand für eine komplette Analyse aller möglichen Einzelstoffe ist für eine Qualitätsüberwachung praktisch nicht zu leisten. Ein Weg aus diesem Dilemma könnte, neben der quantitativen Bestimmung durch Target-Bestimmungsmethoden, ein Screening des Stoffgemisches mit einer wirkungsbezogenen Analytik sein.
Die Ziele, die mit dem Projekt OxiScreen erreicht werden sollten, waren folgende:
- Evaluierung der Praxistauglichkeit von wirkungsorientierten Biotests für die Labors der Wasserversorger
- Praxisnahe Überprüfung der Wirkung verschiedener oxidativer Verfahren (Chlorierung / Ozonung / Ozonung + AOP) auf ausgewählte hormonaktive Substanzen und Spurenstoffe

description: In den letzten 50 Jahren hat sich die Wasserqualität der Schweizer Gewässer stark verbessert, dies nicht zuletzt wegen des hohen technischen Stands der Abwasserentsorgung und -reinigung. Heutzutage ist der Gewässerschutz u.a. mit der Problematik der Mikroverunreinigungen konfrontiert. Zu diesen Spurenstoffen zählen auch östrogen-aktive Substanzen, wie z.B. Östron (E1), 17β-Östradiol (E2) und 17-Ethinylöstradiol (EE2). Diese Substanzen sind bereits in sehr niedrigen Konzentrationen problematisch in Gewässern. Aus diesem Grund hat das Ökotoxzentrum der Schweiz einen akuten Ökotoxizitätswert von 0.4 ng/L für hormonaktive Subtanzen vorgeschlagenen. In dieser Studie wurden nun 20 verschiedene Abwasserreinigungsanlagen (ARA) des Kantons Zürich mittels dem planar-Yeast Estrogen Screen (planar-YES), welcher Dünnschichtchromatographie und Biotest koppelt, auf östrogenaktive Substanzen untersucht. Nur in vier Abwasserproben wurden keine östrogen-aktiven Substanzen gefunden, jedoch die Hälfte der 24 Proben wies eine Östrogenaktivität auf, die über dem vorgeschlagenen Schwellenwert von 0.4 ng/l lag. Die maximale Anzahl detektierter östrogen-aktiver Substanzen betrug 8 und wurde im Ablauf einer Vorklärung gefunden. Im Ablauf der Nachklärungen lag die maximale Anzahl östrogen-aktiver Substanzen bei 6, im Ablauf nach Filtration nurmehr bei 5. Die durchgeführte Studie zeigt klar, dass der planar-YES geeignet ist, in grosser Auflösung östrogene Aktivitätsprofile und deren zeitliche Änderung in ARA zu erstellen. Der planar-YES ist damit ein effizienter und kostengünstiger Biotest, der eine detaillierte Charakterisierung der östrogenen Aktivität von Abwasserproben erlaubt

description: We present a stream-tube model of oxygen exchange inside a human placenta functional unit (a placentone). The effect of villi density on oxygen transfer efficiency is assessed by numerically solving the diffusion-convection equation in a 2D+1D geometry for a wide range of villi densities. For each set of physiological parameters, we observe the existence of an optimal villi density providing a maximal oxygen uptake as a trade-off between the incoming oxygen flow and the absorbing villus surface. The predicted optimal villi density $0.47\pm0.06$ is compatible to previous experimental measurements. Several other ways to experimentally validate the model are also proposed. The proposed stream-tube model can serve as a basis for analyzing the efficiency of human placentas, detecting possible pathologies and diagnosing placental health risks for newborns by using routine histology sections collected after birth.

On the Invariance of Goedel's Second Theorem with Regard to Numberings

description: The prevalent interpretation of Gödel’s Second Theorem states that a sufficiently adequate and consistent theory does not prove its consistency. It is however not entirely clear how to justify this informal reading, as the formulation of the underlying mathematical theorem depends on several arbitrary formalisation choices. In this paper I examine the theorem’s dependency regarding Gödel numberings. I introduce deviant numberings, yielding provability predicates satisfying Löb’s conditions, which result in provable consistency sentences. According to the main result of this paper however, these “counterexamples” do not refute the theorem’s prevalent interpretation, since once a natural class of admissible numberings is singled out, invariance is maintained.
Sensitivity of a Future High Energy $e^+ e^-$ Collider to $Z^\prime$ Bosons

description: We consider the capability of a future high energy $e^+ e^-$ collider to search for the $Z^\prime$ bosons associated with a $U(1)^\prime$ gauge extension of the Standard Model. Even for $Z^\prime$ masses well above the center of mass energy of the collider, the rates of production of $e^+ e^-$, $μ^+ μ^-$, unflavored jets, and $b$-tagged jets can reveal the presence of virtual $Z^\prime$ exchange. We consider collider configurations with center-of-mass energy 200, 300, and 500 GeV, and show how various classes of $Z^\prime$ model-lines can be probed with $100~{\rm fb}^{-1}$ of integrated luminosity. We find that for order one couplings, $Z^\prime$ masses on the order of several TeV can be discovered, depending on the collider energy. Our results suggest that a 200 GeV collision energy is unlikely to discover any of the $Z^\prime$ models we consider that would not have already been visible in late stages of LHC running, but could still help refine understanding of the couplings and distinguish between different models. For $e^+ e^-$ collision energies of 300 GeV, parameter space beyond the reach of the LHC becomes accessible.

description: The absence of supersymmetry or other new physics at the Large Hadron Collider (LHC) has lead many to question naturalness arguments. With Bayesian statistics, we argue that natural models are most probable and that naturalness is not merely an aesthetic principle. We calculate a probabilistic measure of naturalness, the Bayesian evidence, for the Standard Model (SM) with and without quadratic divergences, confirming that the SM with quadratic divergences is improbable. We calculate the Bayesian evidence for the Constrained Minimal Supersymmetric Standard Model (CMSSM) with naturalness priors in three cases: with only the $M_Z$ measurement; with the $M_Z$ measurement and LHC measurements; and with the $M_Z$ measurement, $m_h$ measurement and a hypothetical null result from a $\sqrt{s}=100\,\text{TeV}$ Very Large Hadron Collider (VLHC) with $3000/\text{fb}$. The "fine-tuning price" of the VLHC given LHC results would be $\sim400$, which is slightly less than that of the LHC results given the electroweak scale ($\sim500$).

description: In this paper we examine the interaction of $D N$ and $D^* N$ states, together with their coupled channels, by using an extension of the local hidden gauge formalism from the light meson sector, which is based on heavy quark spin symmetry. The scheme is based on the use of the impulse approximation at the quark level, with the heavy quarks acting as spectators, which occurs for the dominant terms where there is the exchange of a light meson. The pion exchange and the Weinberg-Tomozawa interactions are generalized and with this dynamics we look for states generated from the interaction, with a unitary coupled channels approach that mixes the pseudoscalar-baryon and vector-baryon states. We find two states with nearly zero width which are associated to the $Λ_c(2595)$ and $Λ_c(2625)$. The lower state, with $J^P = 1/2^-$, couples to $D N$ and $D^* N$, and the second one, with $J^P = 3/2^-$, to $D^* N$. In addition to these two $Λ_c$ states, we find four more states with $I=0$, one of them nearly degenerate in two states of $J=1/2,\ 3/2$. Furthermore we find three states in $I=1$, two of them degenerate in $J=1/2, 3/2$.

description: We study the consequence of the neutrino mass anarchy on cosmology, in particular the total mass of neutrinos and baryon asymmetry through leptogenesis. We require independence of measure in each mass matrix elements in addition to the basis independence, which uniquely picks the Gaussian measure. A simple approximate U(1) flavor symmetry makes leptogenesis highly successful. Correlations between the baryon asymmetry and the light-neutrino quantities are investigated. We also discuss possible implications of recently suggested large total mass of neutrinos by the SDSS/BOSS data.

description: We study the entanglement spectrum of spin-1/2 XXZ ladders both analytically and numerically. Our analytical approach is based on perturbation theory starting either from the limit of strong rung coupling, or from the opposite case of dominant coupling along the legs. In the former case we find to leading order that the entanglement Hamiltonian is also of nearest-neighbor XXZ form although with an, in general, renormalized anisotropy. For the cases of XX and isotropic Heisenberg ladders no such renormalization takes place. In the Heisenberg case the second-order correction to the entanglement Hamiltonian consists of a renormalization of the nearest-neighbor coupling plus an unfrustrated next-nearest-neighbor coupling. In the opposite regime of strong coupling along the legs, we point out an interesting connection of the entanglement spectrum to the Lehmann representation of single-chain spectral functions of operators appearing in the physical Hamiltonian coupling the two chains.
Valuing Customer Portfolios under Risk-Return-Aspects: A Model-based Approach and its Application in the Financial Services Industry

description: For identifying and selecting the most profitable customers in terms of the shareholder value, the Customer Lifetime Val-ue (CLV) gained broad attention in marketing literature. However, in this paper, the authors argue that the CLV does not take into account the risk associated with customer relationships and consequently does not conform to the principle of shareholder value. Therefore, a quantitative model based on financial portfolio selection theory is presented that considers the expected CLV of customer segments as well as their risk. The latter includes the correlation among the segments. It is shown how imperfect correlation among segments may be employed to maximize the value of the customer portfolio. Since portfolio selection theory does not allow for the consideration of fixed costs, it is extended by a heuristic method consisting of two algorithms, referred to as “subtract”- and “add”-approaches.

description: yberphysical systems (CPSs) are expected to operate in safety-critical scenarios, and are increasingly getting distributed and physically separated. CPSs are characterized by complex dynamical behavior arising from emergent inter-agent interactions, having discrete logic-based programs, data-driven methods employed in-the-loop, or by simply having highly nonlinear dynamics. Despite this, safety and security properties for CPSs need to be computed, often in real-time over analytically accurate solutions of the associated high dimensional partial differential equations (PDEs). In this dissertation, we investigate numerical approximation schemes to compute safety properties (or reachable sets) for CPSs with differing natures of complexities, without solving the associated PDEs. We solve for reachable sets for unknown dynamical systems with polynomial approximations. Similar approximation schemes can be extended to multi-agent systems and dynamical systems with neural-networks-in-the-loop. Such systems are increasingly applicable in real life instances, such as internet of things, urban air mobility, and data-driven controllers in-the-loop. We utilize the system's trajectory data to compute equivalent system models, and utilize the data-driven models to find approximate reachable sets using polytopic or interval approximations, thereby side stepping PDE solutions. We also investigate cyberphysical vulnerabilities in CPSs from emergent multi-agent behavior, and single agent interacting with multiple controllers via supervisory cyber layers. Each problem is accompanied with associated illustrative examples and numerical simulations. Finally, we present an extensive discussion of possible directions for future work, both, that result directly from the works presented in this dissertation, and those that stem from the assumptions that can be handled immediately.

description: Respiratory function tests are used in the daily medical practice of the pulmonologist, however they are also useful for every clinician to assess the adequacy of the respiratory system. In addition to spirometry, which is the most basic examination for the pulmonologist, the measurement of diffusion capacity and plethysmography help in the differential diagnosis of respiratory diseases. More modern tests, such as the measurement of exhaled nitric oxide and capnography are helpful in the monitoring and examination of chronic lung diseases. Finally, the increasing use of more complex tests, such as the cardiorespiratory fatigue provide information in addition to respiratory and cardiovascular and highlight the magic of modern pulmonology. The aim of this book is to be a useful aid for every clinician and a tool for in-depth study for anyone with a special interest in pulmonology. In addition, it will provide useful knowledge for doctors of other specialties, as it is often observed that respiratory assessment is a black box. As the educational gaps observed in this topic are known, we believe that this book will be used by young doctors.
description: Οι λειτουργικές δοκιμασίες του αναπνευστικού είναι εξετάσεις που χρησιμοποιούνται στην καθημερινή ιατρική πράξη του πνευμονολόγου, ωστόσο είναι χρήσιμες και για τον κάθε κλινικό ιατρό για την εκτίμηση της επάρκειας του αναπνευστικού συστήματος. Εκτός από τη σπιρομέτρηση, που αποτελεί τη βασικότερη εξέταση για τον πνευμονολόγο, η μέτρηση της διαχυτικής ικανότητας και η πληθυσμογραφία βοηθούν στη διαφορική διάγνωση των αναπνευστικών νόσων. Πιο σύγχρονες εξετάσεις, όπως η μέτρηση του εκπνεομένου μονοξειδίου του αζώτου και η καπνογραφία είναι βοηθητικές στην παρακολούθηση και εξέταση χρονίων πνευμονικών νόσων. Τέλος, η αυξανόμενη χρήση πιο σύνθετων εξετάσεων, όπως η καρδιοαναπνευστική δοκιμασία κόπωσης παρέχει πληροφορίες εκτός από το αναπνευστικό και για το καρδιαγγειακό και αναδεικνύει τη μαγεία της σύγχρονης πνευμονολογίας. Στόχος του βιβλίου αυτού είναι να αποτελέσει ένα χρήσιμο βοήθημα για κάθε κλινικό ιατρό και ένα εργαλείο για εμβάθυνση για όποιον ενδιαφέρεται ιδιαίτερα για την πνευμονολογία. Επιπλέον, θα προσφέρει χρήσιμες γνώσεις και για γιατρούς άλλων ειδικοτήτων, καθώς συχνά παρατηρείται το φαινόμενο η εκτίμηση του αναπνευστικού να αποτελεί ένα μαύρο κουτί. Καθώς είναι γνωστά τα εκπαιδευτικά κενά που παρατηρούνται στο συγκεκριμένο θέμα πιστεύουμε ότι αυτό το βιβλίο θα αξιοποιηθεί από τους νέους γιατρούς.

description: We study the action of $\operatorname{Gal}(\overline{\mathbb{Q}}/\mathbb{Q})$ on the category of Belyi functions (finite, étale covers of $\mathbb{P}^1_{\overline{\mathbb{Q}}}\setminus \{0,1,\infty\}$). We describe a new combinatorial $\operatorname{Gal}(\overline{\mathbb{Q}}/\mathbb{Q})$-invariant for whose monodromy cycle types above $0$ and $\infty$ are the same. We use a version of our invariant to prove that $\operatorname{Gal}(\overline{\mathbb{Q}}/\mathbb{Q})$ acts faithfully on the set of Belyi functions whose monodromy cycle types above 0 and $\infty$ are the same; the proof of this result involves a version of Belyi's Theorem for odd degree morphisms. Using our invariant, we obtain that for all $k < 2^{\sqrt{\frac{2}{3}}}$ and all positive integers $N$, there is an $n \le N$ such that the set of degree $n$ Belyi functions of a particular rational Nielsen class must split into at least $Ω\left(k^{\sqrt{N}}\right)$ Galois orbits.

description: We derive a formula for the time-energy costs of general quantum channels proposed in [Phys. Rev. A 88, 012307 (2013)]. This formula allows us to numerically find the time-energy cost of any quantum channel using positive semidefinite programming. We also derive a lower bound to the time-energy cost for any channels and the exact the time-energy cost for a class of channels which includes the qudit depolarizing channels and projector channels as special cases.

description: We analyze the statistics of work generated by a gradient flow to stretch a nonlinear polymer. We obtain the Large Deviation Function (LDF) of the work in the full range of appropriate parameters by combining analytical and numerical tools. The LDF shows two distinct asymptotes: "near tails" are linear in work and dominated by coiled polymer configurations, while "far tails" are quadratic in work and correspond to preferentially fully stretched polymers. We find the extreme value statistics of work for several singular elastic potentials, as well as the mean and the dispersion of work near the coil-stretch transition. The dispersion shows a maximum at the transition.

description: Musculoskeletal disorders (MSDs) are the main cause of pain leading to high economic burden and psychosocial disadvantages. In addition, psychological stress impacts the overall health as well as the quality of life. Elementary school teachers clearly are a cohort with a high risk of MSDs and stress. The 'BelaPrim' study was conducted to determine the physical and psychological conditions of elementary school teachers in Upper Austria and to investigate the influence of physical and psychological parameters on MSDs. Physical and mental strain was determined with the Nordic Musculoskeletal Questionnaire (NMQ) and the 11-item short version of a German work-related behaviour and experience assessment (AVEM), respectively. Despite a high prevalence of MSDs, high scores were found on personality dimensions. Furthermore, qualitative results indicated the need of administrative/pedagogical support. A linear regression model showed that body height (+), work engagement (+), and emotions (−) are predictors for the occurrence of back pain. Practitioner summary: Despite a high proportion of physical complaints, Upper Austrian elementary school teachers show good mental health. Body height, a high work engagement, and low level of emotions are predictors for the occurrence of back pain. Health initiatives for elementary schools should have a multifactorial view to improve teachers’ health.

description: One of the challenges with working from home (WFH) is the question of its effect on health and well-being. The impact of home working on health has so far not been studied extensively. We address this gap by investigating the association between internal recovery, operationalised as rest break frequency (low, medium, and high) during the working day, on self-reported musculoskeletal pain, and post-work recovery symptoms in WFH knowledge workers (n = 382). The analysis showed that failing to take frequent breaks was associated with a dose-response increased risk of reporting headaches. For post-work recovery symptoms, failing to take rest breaks throughout the day was associated with an increased risk of reporting psychological fatigue, physical fatigue, and sleep problems, and a decreased risk of psychologically detaching from work and experiencing adequate rest. Our findings emphasise the importance of remote workers taking recovery breaks from work demands in the maintenance of health and well-being. Practitioner Summary: For the foreseeable future, many knowledge workers will be obliged to work from home for at least, some days of the week. It is therefore important for workers to learn to regulate their behaviour, and workers need to be educated about the value of taking regular rest breaks throughout the working day.
