description: The cluster 1RXS J0603.3+4214 is a merging galaxy cluster that hosts three radio relics and a giant radio halo. The northern relic, the Toothbrush, is 1.9-Mpc long and has an unusual linear morphology. According to simple diffusive shock acceleration theory, its radio spectral index indicates a Mach number of 3.3-4.6. Here, we present results from a deep XMM-Newton observation of the cluster. We observe two distinct cluster cores that have survived the merger. The presence of three shocks at or near the locations of the radio relics is confirmed by density and temperature discontinuities. However, the observation poses several puzzles that challenge our understanding of radio relics: (i) at the Toothbrush, the shock Mach number is not larger than 2, in apparent conflict with the shock strength predicted from the radio spectrum; (ii) at the Toothbrush, the shock front is, in part, spatially offset from the radio emission; (iii) at the eastern relic, we detect a temperature jump corresponding to a Mach number of approximately 2.5, but there is no associated surface brightness discontinuity. We discuss possible explanations for these findings.

description: We give simple necessary and sufficient conditions for the $\frac{\partial}{\partial t}$-transcendence of the solutions to a parameterized second order linear differential equation of the form \frac{\partial^2 Y}{\partial x^2} - p \frac{\partial Y}{\partial x} = 0, where $p\in F(x)$ is a rational function in $x$ with coefficients in a $\frac{\partial}{\partial t}$-field $F$. This result is crucial for the development of an efficient algorithm to compute the parameterized Picard-Vessiot group of an arbitrary parameterized second-order linear differential equation over $F(x)$. Our criteria imply, in particular, the $\frac{\partial}{\partial t}$-transcendence of the incomplete Gamma function $γ(t,x)$, generalizing a result of Johnson, Reinhart, and Rubel [9].

description: This paper studies several problems concerning channel inclusion, which is a partial ordering between discrete memoryless channels (DMCs) proposed by Shannon. Specifically, majorization-based conditions are derived for channel inclusion between certain DMCs. Furthermore, under general conditions, channel equivalence defined through Shannon ordering is shown to be the same as permutation of input and output symbols. The determination of channel inclusion is considered as a convex optimization problem, and the sparsity of the weights related to the representation of the worse DMC in terms of the better one is revealed when channel inclusion holds between two DMCs. For the exploitation of this sparsity, an effective iterative algorithm is established based on modifying the orthogonal matching pursuit algorithm.

description: In Bayer and Macrì (J Am Math Soc 27(3):707–752, 2014), the first author and Macrì constructed a family of nef divisors on any moduli space of Bridgeland-stable objects on a smooth projective variety X. In this article, we extend this construction to the setting of any separated scheme Y of finite type over a field, where we consider moduli spaces of Bridgeland-stable objects on Y with compact support. We also show that the nef divisor is compatible with the polarising ample line bundle coming from the GIT construction of the moduli space in the special case when Y admits a tilting bundle and the stability condition arises from a θ-stability condition for the endomorphism algebra. Our main tool generalises the work of Abramovich–Polishchuk (J Reine Angew Math 590:89–130, 2006) and Polishchuk (Mosc Math J 7(1):109–134, 2007): given a t-structure on the derived category Dc(Y) on Y of objects with compact support and a base scheme S, we construct a constant family of t-structures on a category of objects on Y×S with compact support relative to S.

Действующее законодательство содержит недостаточное количество положений, регламентирующих вопросы наследования обязательственных прав из договоров аренды, вследствие чего возникают проблемы в правоприменительной практике. В статье приводятся противоречивые позиции судов по вопросам наследования прав из договоров аренды. По итогам исследования автор приходит к выводу о необходимости внесе�ния дополнений в статью 617 Гражданского кодекса Российской Федерации. Кроме того, отмечается целесообразность дачи ВС РФ разъяснений по вопросу наследования обязательственных прав из заключенных без проведения торгов договоров аренды земельных участков, находящихся в государственной и муниципальной собственности

description: The LISA Pathfinder mission is a technology demonstrator for a LISA-like gravitational wave observatory in space. Its first results already exceed the expectations. This is also true for the optical metrology system which measures the distance in between the two free-floating test masses with unpreceded precision. One noise source that can possibly affect the measurement is the laser frequency noise. It is measured with a dedicated interferometer and suppressed with a control loop. We measured the laser frequency noise and characterised the control loop in flight. The coupling of laser frequency noise into the measured phase is directly proportional to the path length difference in the respective interferometer. Dedicated experiments have been performed to estimate the path length difference in flight. In addition, this frequency stabilisation scheme is also a possible solution for the LISA mission.

description: The fourth international workshop on Computational Models for Cell Processes (CompMod 2013) took place on June 11, 2013 at the Åbo Akademi University, Turku, Finland, in conjunction with iFM 2013. The first edition of the workshop (2008) took place in Turku, Finland, in conjunction with Formal Methods 2008, the second edition (2009) took place in Eindhoven, the Netherlands, as well in conjunction with Formal Methods 2009, and the third one took place in Aachen, Germany, in conjunction with CONCUR 2013. This volume contains the final versions of all contributions accepted for presentation at the workshop. The goal of the CompMod workshop series is to bring together researchers in Computer Science and Mathematics (both discrete and continuous), interested in the opportunities and the challenges of Systems Biology. The Program Committee of CompMod 2013 selected 3 papers for presentation at the workshop. In addition, we had two invited talks and five informal presentations. The scientific program of the workshop spans an interesting mix of approaches to systems and even synthetic biology, encompassing several different modeling approaches, ranging from quantitative to qualitative techniques, from continuous to discrete mathematics, and from deterministic to stochastic methods. We thank our invited speakers Daniela Besozzi (Universita degli Studi di Milano, Milano, Italy) and Juho Rousu (Aalto University, Finland) for accepting our invitation and for presenting some of their recent results at CompMod 2013. The technical contributions address the mathematical modeling of the PDGF signalling pathway, the canonical labelling of site graphs, rule-based modeling of polymerization reactions, rule-based modeling as a platform for the analysis of synthetic self-assembled nano-systems, robustness analysis of stochastic systems, an algebraic approach to gene assembly in ciliates, and large-scale text mining of biomedical literature.

description: Finite-size systems of the one-dimensional attractive Hubbard model with random potential are studied as an effective model for doped semiconductor nanotubes. We calculate the binding energy of Cooper pairs and pair correlation function by the density-matrix renormalization group method. We show that, when the scattering potential is strong, there appears the ground state where Cooper pairs are formed but are localized spatially, with a decay length of pair correlation smaller than the system size. Experimental relevance is discussed. © 2009 IOP Publishing Ltd.

description: A polarized atomic beam source was developed for the polarized internal storage-cell gas target at the magnet spectrometer ANKE of COSY-Jülich. The intensities of the beams injected into the storage cell, measured with a compression tube, are $7.5\cdot 10^{16}$ hydrogen atoms/s (two hyperfine states) and $3.9\cdot 10^{16}$ deuterium atoms/s (three hyperfine states). For the hydrogen beam the achieved vector polarizations are $p_{\rm z}\approx\pm0.92$. For the deuterium beam, the obtained combinations of vector and tensor ($p_{\rm zz}$) polarizations are $p_{\rm z}\approx\pm 0.90$ (with a constant $p_{\rm zz}\approx +0.86$), and $p_{\rm zz}=+0.90$ or $p_{\rm zz}=-1.71$ (both with vanishing $p_{\rm z}$). The paper includes a detailed technical description of the apparatus and of the investigations performed during the development.

description: Recent experimental results from GEO600 operating with a DC readout and a tuned signal recycling cavity are reported. Compared to the S5/Astrowatch setup, two major changes in the configuration have been implemented: the control readout to keep the interferometer on the dark fringe is changed from heterodyne to homodyne readout and the signal recycling cavity is shifted from a 550 Hz detuning to a 0 Hz detuning (also called tuned). As preliminary experiments showed, the tuned DC readout sensitivity is similar to the heterodyne one. To take advantage of the new DC readout detection scheme, an Output Mode Cleaner (OMC) has to be installed. The design, building and testing of the GEO OMC, which consists of a 4 mirrors monolithic ring cavity, will also be presented in this article.

description: We describe a multi-mode quantum memory for propagating microwave photons that combines a solid-state spin ensemble resonantly coupled to a frequency tunable single-mode microwave cavity. We first show that high efficiency mapping of the quantum state transported by a free photon to the spin ensemble is possible both for strong and weak coupling between the cavity mode and the spin ensemble. We also show that even in the weak coupling limit unit efficiency and faithful retrieval can be obtained through time reversal inhomogeneous dephasing based on spin echo techniques. This is possible provided that the cavity containing the spin ensemble and the transmission line are impedance matched. We finally discuss the prospects for an experimental implementation using a rare-earth doped crystal coupled to a superconducting resonator.

description: Требования к физической подготовленности и общему физическому состоянию со�трудников полиции постоянно ужесточаются. Общество хочет видеть молодых, опытных, физически развитых сотрудников, которые внушают доверие и безопасность с первого взгляда. Существующая сегодня профессионально-прикладная физическая подготовка заключается в том, что за достаточно короткий промежуток времени преподавателям необходимо практически с нуля обучить слушателей различным приемам силового задержания, борьбы и бросковой технике, при этом оценка общей фи�зической подготовки отходит на второй план, а именно основной упор делается на контрольных нор�мативах, которые слушателям по окончании обучения необходимо сдать. Таким образом, тот факт, что одна часть физической подготовки отходит на второй план не может сказаться положительно, так как от физической выносливости и силы также зависит успешность выполнения служебных задач Про�фессионально-прикладная физическая подготовка формирует необходимость разработки такой мето�дики обучения, которая позволит в достаточном объеме развивать все необходимые качества и доби�ваться оптимальной формы для успешного несения службы среди сотрудников полиции. Основной задачей преподавательского состава является подготовить универсального если можно так выразить�ся сотрудника, готового нести службу во всех подразделениях органов внутренних дел. Работа сотруд�ников полиции разнопланова, специфична, непостоянна, сопряжена с постоянным стрессом и опасно�стью. В этой связи для начала необходимо отметить, что перед полицейскими стоит задача по обеспе�чению правопорядка. Это деятельность полицейских, которая подразумевает что в ходе несения служ�бы они в большой степени будут производить задержания правонарушителей непосредственно на месте преступления. Это означает, что сотрудник полиции должен быть выносливым, физически силь�ным, уметь применять приемы силового задержания, борьбы, быть ловким и гибким. Именно когда все эти аспекты физической подготовки доведены до достаточно высокого уровня можно утверждать, что вероятность успешного выполнения служебных задач у этого сотрудника высока, а его подготовка соответствует всем необходимым требованиям

description: We generate stellar distribution functions (DFs) in triaxial haloes in order to examine the reliability of slopes $Γ\equiv Δ{\rm log} M / Δ{\rm log} r$ inferred by applying mass estimators of the form $M\propto R_eσ^2$ (i.e. assuming spherical symmetry, where $R_e$ and $σ$ are luminous effective radius and global velocity dispersion, respectively) to two stellar sub-populations independently tracing the same gravitational potential. The DFs take the form $f(E)$, are dynamically stable, and are generated within triaxial potentials corresponding directly to subhaloes formed in cosmological dark-matter-only simulations of Milky Way and galaxy cluster haloes. Additionally, we consider the effect of different tracer number density profiles (cuspy and cored) on the inferred slopes of mass profiles. For the isotropic DFs considered here, we find that halo triaxiality tends to introduce an anti-correlation between $R_e$ and $σ$ when estimated for a variety of viewing angles. The net effect is a negligible contribution to the systematic error associated with the slope of the mass profile, which continues to be dominated by a bias toward greater overestimation of masses for more-concentrated tracer populations. We demonstrate that simple mass estimates for two distinct tracer populations can give reliable (and cosmologically meaningful) lower limits for $Γ$, irrespective of the degree of triaxiality or shape of the tracer number density profile.

SELF-PROTECTIVE EPISODIC SIMULATIONS MOTIVATE NEGATIVE SOCIAL BEHAVIORS IN LONELY PEOPLE

description: Loneliness can be an enduring condition, with the stability of loneliness comparable to that of a personality trait. The Evolutionary Theory of Loneliness (ETL) posits that loneliness is a self-perpetuating condition; lonely people prioritize self-protection over connecting with others. To self-protect, lonely people engage in increased hostility and avoidance and decreased prosocial behaviors. Engaging in these behaviors perpetuates their loneliness by eroding their social networks. I hypothesize that self-protective episodic simulations of rejection may be an underlying mechanism that drives negative social behaviors. To assess the effects of episodic simulations on the stability of loneliness, I conducted a longitudinal assessment of participants' unmanipulated episodic simulations of social interactions and ratings of loneliness. Participants were 207 undergraduate students at the University of Maryland who completed up to four sequential weekly assessments. Multilevel modeling was used to assess within subjects change in social behaviors, social perceptions, and episodic simulations. I found evidence to support episodic simulations of rejection predicted next week's prosocial behaviors, social avoidance, and hostility. Prosocial behaviors and hostility, in turn, predicted loneliness. I did not find evidence to support the hypothesis that loneliness predicts the following week's hostility. The results highlight the potential influence episodic simulations of rejection have on social behaviors and loneliness. Contrary to ETL, I did not find any support for the hypothesis that loneliness predicts future hostility.

description: The AEI 10 m Prototype is in its designing phase and will provide a test-bed for very sensitive interferometric experiments, such as the sub-SQL interferometer. It will test new techniques to reach - and even surpass - the Standard Quantum Limit. The experience and knowledge that can be gained from this experiment can be applied to large-scale interferometric gravitational detectors to improve the detector sensitivities. In order for the sub-SQL interferometer to achieve the required sensitivity all limiting noise sources need to be suppressed sufficiently. Noise sources can include seismic noise, thermal noise, and laser noise; laser frequency noise will be the main focus of this document. The laser frequency noise will be suppressed to a level of 10-4 Hz/√Hz at 20 Hz dropping to below 10-6 Hz/√Hz at 1kHz. The proposed design to suppress the laser frequency noise with a ring cavity is described in this paper.

description: Photoproduction of $π^{0}π^{0}$ and $π^{0}π^{\pm}$ pairs from nuclei has been measured over a wide mass range ($^2$H, $^{7}$Li, $^{12}$C, $^{40}$Ca, and $^{\rm nat}$Pb) for photon energies from threshold to 600 MeV. The experiments were performed at the MAMI accelerator in Mainz, using the Glasgow photon tagging spectrometer and a 4$π$ electromagnetic calorimeter consisting of the Crystal Ball and TAPS detectors. A shift of the pion-pion invariant mass spectra for heavy nuclei to small invariant masses has been observed for $π^0$ pairs but also for the mixed-charge pairs. The precise results allow for the first time a model-independent analysis of the influence of pion final-state interactions. The corresponding effects are found to be large and must be carefully considered in the search for possible in-medium modifications of the $σ$-meson. Results from a transport model calculation reproduce the shape of the invariant-mass distributions for the mixed-charge pairs better than for the neutral pairs, but also for the latter differences between model results and experiment are not large, leaving not much room for $σ$-in-medium modification.

Part of the transition will be the move from a heterodyne readout to a DC readout scheme. DC readout performance will be limited by higher order optical modes and control sidebands present at the output port. For optimum performance of DC readout an output mode cleaner (OMC) will clean the output beam of these contributions. Inclusion of an OMC will introduce new noise sources whose magnitudes needed to be estimated and for which new control systems will be needed. In this article we set requirements on the performance of these control systems and investigate the simulated performance of different designs.

description: In the 2022-2023 flu season, the Center for Disease Control (CDC) estimated 21,000 deaths and 31 million symptomatic illnesses in the United States. Current FDA approved antivirals for influenza are grouped into three categories, matrix protein 2 (M2) inhibitors, neuraminidase inhibitors (NAI) and polymerase acidic protein cap-dependent endonuclease (CEN) inhibitors. However, limitations of these treatments have been evident. For example, NAI inhibitors require early treatment to be efficacious and some influenza strains can develop resistance to both NAI and CEN inhibitors. Thus, there is a need for new classes of antivirals as well as better understanding of influenza transmission and monitoring of influenza to inform development of efficacious interventions. In chapter 2 we describe how we design biomaterials inspired by the physiological characteristics of mucus to capture and trap pathogens. We performed studies to establish this material as a suitable substrate for viral capture and release after collection using advanced aerosol capture technology. In chapter 3, we formulate an antiviral based around polyinosinic polycytidylylic acid (polyIC). PolyIC is commonly used in research as an adjuvant in vaccine delivery through its targeting of Toll like receptor 3 (TLR3). This pathway also results in type 1 and 3 interferon production, which in turn stimulate a range of antiviral mechanisms. Because of this, it has also been investigated as a prophylactic or treatment to various viruses, including hepatitis B virus, human immunodeficiency virus and rhinovirus. However, due to stability and toxicity concerns, it has not been implemented as an inhaled treatment to induce local immunity in the lungs at the site of infection. Towards this end, we used polyethylene imine-polyethylene glycol (PEI-PEG) copolymer to condense PolyIC into nanoparticles to enhance their bioavailability in target cells. By combining the two, we can utilize the antiviral capabilities of Poly(IC) while minimizing the dosage concentration to therapeutic levels.
Quantized slow blow up dynamics for the corotational energy critical harmonic heat flow

description: We consider the energy critical harmonic heat flow from $\Bbb R^2$ into a smooth compact revolution surface of $\Bbb R^3$. For initial data with corotational symmetry, the evolution reduces to the semilinear radially symmetric parabolic problem $$\partial_t u -\pa^2_{r} u-\frac{\pa_r u}{r} + \frac{f(u)}{r^2}=0$$ for a suitable class of functions $f$ . Given an integer $L\in \Bbb N^*$, we exhibit a set of initial data arbitrarily close to the least energy harmonic map $Q$ in the energy critical topology such that the corresponding solution blows up in finite time by concentrating its energy $$\nabla u(t,r)-\nabla Q(\frac{r}{ł(t)})\to u^* in L^2$$ at a speed given by the {\it quantized} rates: $$ł(t)=c(u_0)(1+o(1))\frac{(T-t)^L}{|\log (T-t)|^{\frac{2L}{2L-1}}},$$ in accordance with the formal predictions [3]. The case L=1 corresponds to the stable regime exhibited in [37], and the data for $L\ge 2$ leave on a manifold of codimension $(L-1)$ in some weak sense. Our analysis lies in the continuation of [36,32,37] by further exhibiting the mechanism for the existence of the excited slow blow up rates and the associated instability of these threshold dynamics.

description: This paper presents a novel joint torque-based impedance controller for antagonistically driven flexible joints actuated by pneumatic cylinders and compares it with the current state of the art. The work targets on transferring soft-robotics control concepts from classical motor-gear-torque sensor setups to pneumatic systems, with the goal of achieving similar performance levels in comparison to this well established technology. A detailed flexible joint model is derived that incorporates the pneumatic and mechanical dynamics of the proposed antagonistic design. This model is used for analyzing model-based control approaches, which in turn are based on reduced order dynamics. The tendon-based joint level impedance controller enables the simultaneous adjustment of closed-loop stiffness and damping. The proposed scheme shows good simulation results for both, position tracking and compliance performance, respectively. Experimentally, an angular position tracking of 7 Hz could be achieved. Also, stable rigid contacts could be established at considerable impact speed.

description: The rational Calogero model based on the An- 1 root system is spherically reduced to a superintegrable angular model of a particle moving on Sn- 2 subject to a very particular potential singular at the Weyl chamber walls. We review the computation of its energy spectrum (including the eigenstates), conserved charges and intertwining operators shifting the coupling constant by one. These models are deformed in a PT -symmetric manner by judicious complex coordinate transformations, which render the potential less singular. The PT deformation does not change the energy levels but in some cases adds a previously unphysical tower of states. For integral couplings this roughly doubles the previous degeneracy and allows for a conserved nonlinear supersymmetry-type charge. We illustrate the general constructions by presenting the details for the cases of A2 and A3 and point out open questions. © Copyright owned by the author(s) under the terms of the Creative Commons.

The universality of the Carnot theorem

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: It is common in many thermodynamic textbooks to illustrate the Carnot theorem through the usage of diverse state equations for gases, paramagnets, and other simple thermodynamic systems. As it is well-known, the universality of the Carnot efficiency is easily demonstrated in a temperature-entropy diagram, which means that the Carnot efficiecy is independent of the working substance. In this present work we remark that the universality of the Carnot theorem goes beyond the conventional state equations, and it is fulfilled by gas state equations that do not behave as ideal gas in the dilution limit when the volume is infinite. Some of these unconventional state equations have certain thermodynamic "anomalies" that nonetheless do not forbid them from obeying the Carnot theorem. We discuss how this very general behaviour arises from the Maxwell relations, which are connected with a geometrical property expressed through preserving area transformations. A rule is proposed to calculate the Maxwell relations associated with a thermodynamic system by using the preserving area relationships. In this way it is possible to calculate the number of possible preserving area mappings by giving the number of possible Jacobian identities between all pairs of thermodynamic variables included in the corresponding Gibbs equation. This work is intended for undergraduate and specialists in thermodynamics and related areas.

description: The surface passivation properties of aluminium oxide (Al 2O 3) on crystalline Si are compared with the traditional passivation system of silicon nitride (SiN x). It is shown that Al 2O 3 has fundamental advantages over SiN x when applied to the rear of p-type silicon solar cells as well as to the p + emitter of n-type silicon solar cells. Special emphasis is paid to the transfer of Al 2O 3 into industrial solar cell production. We compare different Al 2O 3 deposition techniques suitable for mass production such as ultrafast spatial atomic layer deposition, inline plasma-enhanced chemical vapour deposition and reactive sputtering. Finally, we review the most recent cell results with Al 2O 3passivation and give a brief outlook on the future prospects of Al 2O 3 in silicon solar cell production.

description: The electronic properties of Cu$_{0.07}$Bi$_{2}$Se$_{3}$ have been investigated using Shubnikov-de Haas and optical reflectance measurements. Quantum oscillations reveal a bulk, three-dimensional Fermi surface with anisotropy $k^{c}_{F}/k^{ab}_{F}\approx$ 2 and a modest increase in free-carrier concentration and in scattering rate with respect to the undoped Bi$_{2}$Se$_{3}$, also confirmed by reflectivity data. The effective mass is almost identical to that of Bi$_{2}$Se$_{3}$. Optical conductivity reveals a strong enhancement of the bound impurity bands with Cu addition, suggesting that a significant number of Cu atoms enter the interstitial sites between Bi and Se layers or may even substitute for Bi. This conclusion is also supported by X-ray diffraction measurements, where a significant increase of microstrain was found in Cu$_{0.07}$Bi$_{2}$Se$_{3}$, compared to Bi$_{2}$Se$_{3}$.
