description: Seit den Atomwaffentests 1998 seitens Indiens und Pakistans fiel die militärstrategische Lagebeschreibung zu Südasien düster aus. Dies war zum Teil einem Hype vor allem in westlichen Medien geschuldet. Es wurde für die Analysen darüber hinaus ein stereotypisches Weltbild verwendet, das aus der Ost-WestBlockkonfrontation entnommen war. Die „westliche“ Wahrnehmung kannte (und kennt) nur das Sprachbild des Wettrüstens. Die Autorin und der Autor stellen sowohl die Anwendung dieses Begriffs als auch seine Verengung auf Atomwaffen infrage, wenn es um Sicherheitsfragen und Aufrüstung in Südasien geht.

description: We present a construction (and classification) of certain invariant 2-forms on the real symplectic group. They are used to define a symplectic form on the quotient by a maximal torus and to "lift" a symplectic structure from a symplectic manifold to the bundle of frames. This is a by-product of a failed attempt to prove certain finiteness theorems for basic symplectic cohomologies. In the last part of the paper we include a valid proof.

Robust Transceiver Design for Reciprocal M*N Interference Channel Based on Statistical Linearization Approximation

Year: 2017

description: This paper focuses on robust transceiver design for throughput enhancement on the interference channel (IC), under imperfect channel state information (CSI). In this paper, two algorithms are proposed to improve the throughput of the multi-input multi-output (MIMO) IC. Each transmitter and receiver has respectively M and N antennas and IC operates in a time division duplex mode. In the first proposed algorithm, each transceiver adjusts its filter to maximize the expected value of signal-to-interference-plus-noise ratio (SINR). On the other hand, the second algorithm tries to minimize the variances of the SINRs to hedge against the variability due to CSI error. Taylor expansion is exploited to approximate the effect of CSI imperfection on mean and variance. The proposed robust algorithms utilize the reciprocity of wireless networks to optimize the estimated statistical properties in two different working modes. Monte Carlo simulations are employed to investigate sum rate performance of the proposed algorithms and the advantage of incorporating variation minimization into the transceiver design.

The function to be transformed needs to be evaluated on a grid of points that is independent of the argument of the Bessel function. We demonstrate the accuracy of the algorithm for a wide range of functions, including those that appear in the context of transverse-momentum dependent parton distributions in Quantum Chromodynamics.

description: We introduce a family $\mathbb{M}_{r;f,η}$ of infinitesimal supergroup schemes, which we call multiparameter supergroups, that generalize the infinitesimal Frobenius kernels $\mathbb{G}_{a(r)}$ of the additive group scheme $\mathbb{G}_{a}$. Then, following the approach of Suslin, Friedlander, and Bendel, we use functor cohomology to define characteristic extension classes for the general linear supergroup $GL_{m|n}$, and we calculate how these classes restrict along homomorphisms $ρ: \mathbb{M}_{r;f,η} \rightarrow GL_{m|n}.$ Finally, we apply our calculations to describe (up to a finite surjective morphism) the spectrum of the cohomology ring of the $r$-th Frobenius kernel $GL_{m|n(r)}$ of the general linear supergroup $GL_{m|n}$.

Study of the $K_1(1270)-K_1(1400)$ mixing in the decays $B\to J/ΨK_1(1270), J/ΨK_1(1400)$

description: We studied the B meson decays $B\to J/ΨK_1(1270,1400)$ in the pQCD approach beyond the leading order. With the vertex corrections and the NLO Wilson coefficients included, the branching ratios of the considered decays are $Br(B^+\to J/ΨK_1(1270)^+)=1.76^{+0.65}_{-0.69}\times10^{-3}, Br(B^+\to J/ΨK_1(1400)^+)=7.03^{+2.70}_{-2.52}\times10^{-4}$, and $Br(B^0\to J/ΨK_1(1270)^0)=(1.63^{+0.60}_{-0.64})\times10^{-3}$ with the mixing angle $θ_{K_1}=33^\circ$, which can agree well with the data or the present experimental upper limit within errors. So we support the opinion that $θ_{K_1}\sim33^\circ$ is much more favored than $58^{\circ}$. Furthermore, we also give the predictions for the polarization fractions, direct CP violations from the different polarization components, the relative phase angles for the considered decays with the mixing angle $θ_{K_1}=33^\circ$ and $58^\circ$, respectively. The direct CP violations of the two charged decays $B^+\to J/ΨK_1(1270,1400)^+$ are very small $(10^{-4}\sim10^{-5})$, because there is no weak phase until up to $\mathcal{O}(λ^4)$ with the Wolfenstein parameter $λ=0.22537$. These results can be tested at the running LHCb and forthcoming Super-B experiments.

description: This paper is a continuation of arXiv:1405.1707. We present certain new applications and generalizations of the free field realization of the twisted Heisenberg-Virasoro algebra ${\mathcal H}$ at level zero. We find explicit formulas for singular vectors in certain Verma modules. A free field realization of self-dual modules for ${\mathcal H}$ is presented by combining a bosonic construction of Whittaker modules from arXiv:1409.5354 with a construction of logarithmic modules for vertex algebras. As an application, we prove that there exists a non-split self-extension of irreducible self-dual module which is a logarithmic module of rank two. We construct a large family of logarithmic modules containing different types of highest weight modules as subquotients. We believe that these logarithmic modules are related with projective covers of irreducible modules in a suitable category of ${\mathcal H}$-modules.

description: A form compiler takes a high-level description of the weak form of partial differential equations and produces low-level code that carries out the finite element assembly. In this paper we present the Two-Stage Form Compiler (TSFC), a new form compiler with the main motivation to maintain the structure of the input expression as long as possible. This facilitates the application of optimizations at the highest possible level of abstraction. TSFC features a novel, structure-preserving method for separating the contributions of a form to the subblocks of the local tensor in discontinuous Galerkin problems. This enables us to preserve the tensor structure of expressions longer through the compilation process than other form compilers. This is also achieved in part by a two-stage approach that cleanly separates the lowering of finite element constructs to tensor algebra in the first stage, from the scheduling of those tensor operations in the second stage. TSFC also efficiently traverses complicated expressions, and experimental evaluation demonstrates good compile-time performance even for highly complex forms.

description: The barocaloric effect is still an incipient scientific topic, but it has been attracting an increasing attention in the last years due to the promising perspectives for its application in alternative cooling devices. Here, we present giant values of barocaloric entropy change and temperature change induced by low pressures in PDMS elastomer around room temperature. Adiabatic temperature changes of 12.0 K and 28.5 K were directly measured for pressure changes of 173 MPa and 390 MPa, respectively, associated with large normalized temperature changes (~70 K GPa-1). From adiabatic temperature change data, we obtained entropy change values larger than 140 J kg-1 K-1. We found barocaloric effect values that exceed those previously reported for any promising barocaloric materials from direct measurements of temperature change around room temperature. Our results stimulate the study of the barocaloric effect in elastomeric polymers and broaden the pathway to use this effect in solid-state cooling technologies.

description: The default language input for most open-source tools is left-to-right. However, this excludes a huge community that predominantly uses right-to-left (RTL) language and non-Latin scripts such as Arabic, Urdu and Farsi. Right-to-left functionality in many Open Source technologies has long been neglected. This talk will present the lesson we learned in the Open Science Community Saudi Arabia (OSCSA) while localizing Open Source tools (e.g. the Turing Way), introducing new resources, documentation and open educational materials for open source in Arabic. We will present the challenges we went through and the lessons we learned for increasing the accessibility of Open Source tools to RTL users. OSCSA is part of the International Network of Open Science & Scholarship Communities (INOSC). It is open to individuals from all Arabic-speaking regions without prior knowledge or experience in Open Source. It was built to support inclusive learning communities for novice learners to acquire open-source skills. While growing the community over the last two years, we learned many lessons, which include the know-how for localization of Open Source tools to RTL language. This falls under the internationalization space that is largely overlooked. Localization is especially important in open source projects to support and satisfy the needs of the locales and adapt them to the language and culture of a specific target locale.

description: Anxiety, depression, and suicide are leading causes of disability and death among young people, globally. Schools are an ideal setting to target young people’s mental health, yet young people’s beliefs about and experiences with school mental health and suicide prevention are not well understood. This gap in knowledge contradicts both national and international youth mental health recommendations and the United Nations Convention on the Rights of the Child, which collectively advocate for understanding young people’s perspectives on matters concerning them, including school mental health. Therefore, the Mental Health of Youth Story (MYSTORY) study explored young people’s perspectives on school mental health and suicide prevention using a participatory-based approach incorporating photovoice. MYSTORY consisted of a community/university partnership involving young people as participants (n = 14) and advisors (n = 6). Experiential, reflexive thematic analysis (TA) within a critical approach generated three themes relating to young people’s experiences with and beliefs about school mental health promotion and suicide prevention. Findings highlight the critical role of schools in impacting young people’s mental health, with the need to amplify youth voice and involvement in school mental health evident. Our study addresses an important gap by employing participatory-based approaches to explore young people’s perspectives on school mental health and suicide prevention. This is the first known study to explore young people’s perspectives on their voice and involvement in school mental health. Findings have important implications for youth and school mental health and suicide prevention research, policy, and practice.

Assessing the Habitability of the TRAPPIST-1 System Using a 3D Climate Model

Year: 2017
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The TRAPPIST-1 system provides an extraordinary opportunity to study multiple terrestrial extrasolar planets and their atmospheres. Here we use the National Center for Atmospheric Research Community Atmosphere Model version 4 to study the possible climate and habitability of the planets in the TRAPPIST-1 system. We assume ocean-covered worlds, with atmospheres comprised of N2, CO2, and H2O, and with orbital and geophysical properties defined from observation. Model results indicate that the inner three planets (b, c, and d) presently reside interior to the inner edge of the traditional liquid water habitable zone. Thus if water ever existed on the inner planets, they would have undergone a runaway greenhouse and lost their water to space, leaving them dry today. Conversely the outer 3 planets (f, g, and h) fall beyond the maximum CO2 greenhouse outer edge of the habitable zone. Model results indicate that the outer planets cannot be warmed despite as much as 30 bar CO2 atmospheres, instead entering a snowball state. The middle planet (e) represents the best chance for a presently habitable ocean-covered world in the TRAPPIST-1 system. Planet e can maintain at least some habitable surface area with 0 - 2 bar CO2, depending on the background N2 content. Near present day Earth surface temperatures can be maintained for an ocean-covered planet e with either 1 bar N2 and 0.4 bar CO2, or a 1.3 bar pure CO2 atmosphere.

description: In this research paper approximate mean of signal-to-interference-plus-noise ratio (SINR) under imperfect channel state information (CSI) is computed and maximized for throughput enhancement of MIMO interference networks. Each transmitter and receiver has respectively M and N antennas and network operates in a time division duplex mode. Each transceiver adjusts its filter to maximize the expected value of SINR. The proposed New Approach for Throughput Enhancement under imperfect CSI utilizes the reciprocity of wireless networks to maximize the estimated mean. The sum rate performance of the proposed algorithm is verified using Monte Carlo simulations.

Linear bosonic quantum channels defined by superpositions of maximally distinguishable Gaussian environments
Creators: name: Volkoff, T. J.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A minimal energy quantum superposition of two maximally distinguishable, isoenergetic single mode Gaussian states is used to construct the system-environment representation of a class of linear bosonic quantum channels acting on a single bosonic mode. The quantum channels are further defined by unitary dynamics of the system and environment corresponding to either a passive linear optical element $U_{\text{BS}}$ or two-mode squeezing $U_{\text{TM}}$. The notion of nonclassicality distance is used to show that the initial environment superposition state becomes maximally nonclassical as the constraint energy is increased. When the system is initially prepared in a coherent state, application of the quantum channel defined by $U_{\text{BS}}$ results in a nonclassical state for all values of the environment energy constraint. We also discuss the following properties of the quantum channels: 1) the maximal noise that a coherent system can tolerate, beyond which the linear bosonic attenuator channel defined by $U_{\text{BS}}$ cannot impart nonclassical correlations to the system, 2) the noise added to a coherent system by the phase-preserving linear amplification channel defined by $U_{\text{TM}}$, and 3) a generic lower bound for the trace norm contraction coefficient on the closed, convex hull of energy-constrained Gaussian states.

description: Many current Internet services rely on inferences from models trained on user data. Commonly, both the training and inference tasks are carried out using cloud resources fed by personal data collected at scale from users. Holding and using such large collections of personal data in the cloud creates privacy risks to the data subjects, but is currently required for users to benefit from such services. We explore how to provide for model training and inference in a system where computation is pushed to the data in preference to moving data to the cloud, obviating many current privacy risks. Specifically, we take an initial model learnt from a small set of users and retrain it locally using data from a single user. We evaluate on two tasks: one supervised learning task, using a neural network to recognise users' current activity from accelerometer traces; and one unsupervised learning task, identifying topics in a large set of documents. In both cases the accuracy is improved. We also analyse the robustness of our approach against adversarial attacks, as well as its feasibility by presenting a performance evaluation on a representative resource-constrained device (a Raspberry Pi).

description: There has been great interest in realizing quantum simulators of charged particles in artificial gauge fields. Here, we perform the first quantum simulation explorations of the combination of artificial gauge fields and disorder. Using synthetic lattice techniques based on parametrically-coupled atomic momentum states, we engineer zigzag chains with a tunable homogeneous flux. The breaking of time-reversal symmetry by the applied flux leads to analogs of spin-orbit coupling and spin-momentum locking, which we observe directly through the chiral dynamics of atoms initialized to single lattice sites. We additionally introduce precisely controlled disorder in the site energy landscape, allowing us to explore the interplay of disorder and large effective magnetic fields. The combination of correlated disorder and controlled intra- and inter-row tunneling in this system naturally supports energy-dependent localization, relating to a single-particle mobility edge. We measure the localization properties of the extremal eigenstates of this system, the ground state and the most-excited state, and demonstrate clear evidence for a flux-dependent mobility edge. These measurements constitute the first direct evidence for energy-dependent localization in a lower-dimensional system, as well as the first explorations of the combined influence of artificial gauge fields and engineered disorder. Moreover, we provide direct evidence for interaction shifts of the localization transitions for both low- and high-energy eigenstates in correlated disorder, relating to the presence of a many-body mobility edge. The unique combination of strong interactions, controlled disorder, and tunable artificial gauge fields present in this synthetic lattice system should enable myriad explorations into intriguing correlated transport phenomena.

description: Classification and construction of symmetry protected topological (SPT) phases in interacting boson and fermion systems have become a fascinating theoretical direction in recent years. It has been shown that the (generalized) group cohomology theory or cobordism theory can give rise to a complete classification of SPT phases in interacting boson/spin systems. Nevertheless, the construction and classification of SPT phases in interacting fermion systems are much more complicated, especially in 3D. In this work, we revisit this problem based on the equivalent class of fermionic symmetric local unitary (FSLU) transformations. We construct very general fixed point SPT wavefunctions for interacting fermion systems. We naturally reproduce the partial classifications given by special group super-cohomology theory, and we show that with an additional $\tilde{B}H^2(G_b, \mathbb Z_2)$ (the so-called obstruction free subgroup of $H^2(G_b, \mathbb Z_2)$) structure, a complete classification of SPT phases for three-dimensional interacting fermion systems with a total symmetry group $G_f=G_b\times \mathbb Z_2^f$ can be obtained for unitary symmetry group $G_b$. We also discuss the procedure of deriving a general group super-cohomology theory in arbitrary dimensions.

description: In this paper, we introduce a novel program of fixed-target searches for thermal-origin Dark Matter (DM), which couples inelastically to the Standard Model. Since the DM only interacts by transitioning to a heavier state, freeze-out proceeds via coannihilation and the unstable heavier state is depleted at later times. For sufficiently large mass splittings, direct detection is kinematically forbidden and indirect detection is impossible, so this scenario can only be tested with accelerators. Here we propose new searches at proton and electron beam fixed-target experiments to probe sub-GeV coannihilation, exploiting the distinctive signals of up- and down-scattering as well as decay of the excited state inside the detector volume. We focus on a representative model in which DM is a pseudo-Dirac fermion coupled to a hidden gauge field (dark photon), which kinetically mixes with the visible photon. We define theoretical targets in this framework and determine the existing bounds by reanalyzing results from previous experiments. We find that LSND, E137, and BaBar data already place strong constraints on the parameter space consistent with a thermal freeze-out origin, and that future searches at Belle II and MiniBooNE, as well as recently-proposed fixed-target experiments such as LDMX and BDX, can cover nearly all remaining gaps. We also briefly comment on the discovery potential for proposed beam dump and neutrino experiments which operate at much higher beam energies.

description: We analyze the chiral phase structure of the Nambu--Jona-Lasinio model at finite temperature and density by using the functional renormalization group (FRG). The renormalization group (RG) equation for the fermionic effective potential $V(σ;t)$ is given as a partial differential equation, where $σ:=\bar ψψ$ and $t$ is a dimensionless RG scale. When the dynamical chiral symmetry breaking (D$χ$SB) occurs at a certain scale $t_c$, $V(σ;t)$ has singularities originated from the phase transitions, and then one cannot follow RG flows after $t_c$. In this study, we introduce the weak solution method to the RG equation in order to follow the RG flows after the D$χ$SB and to evaluate the dynamical mass and the chiral condensate in low energy scales. It is shown that the weak solution of the RG equation correctly captures vacuum structures and critical phenomena within the pure fermionic system. We show the chiral phase diagram on temperature, chemical potential and the four-Fermi coupling constant.

Freedom of education and institutional autonomy in Flemish higher education
Creators: name: Couck, Dylan
Publisher: name: Zenodo
Year: 2023

description: The constitutional freedom of education protects the autonomy of universities and university colleges to organise their own education and consequently decide independently on student access, programme offerings, curriculum content ... However, in order to guarantee the right to education or ensure the quality of education, for example, the government can issue regulations that impose limitations on this autonomy. An analysis of legislation and parliamentary preparatory work demonstrates, however, that while doing so, the legislature has had little attention for the constitutionally protected autonomy of higher education institutions. For their part, the higher education institutions too have used their freedom of education relatively little as an argument against government action. In search for explanations for this lack of attention, I interviewed heads of Flemish universities and university colleges. Amongst others, these interviews provide insight in how they perceive their right to freedom of education, how they perceive governance steering and why they think that the freedom of education is mostly absent during the drafting of policy.

description: Agile techniques recently have received attention in developing safety-critical systems. However, a lack of empirical knowledge of performing safety assurance techniques in practice, especially safety analysis into agile development processes prevents further steps. In this article, we aim at investigating the feasibility and the effects of our S-Scrum development process, and stepwise improving and proposing an Optimized S-Scrum development process for safety-critical systems in a real environment. We conducted an exploratory case study in a one-year student project "Smart Home" at the University of Stuttgart, Germany. We participated in the project and collected quantitative and qualitative data from questionnaire, interviews, participant observation, physical artifacts, and documentation review. Furthermore, we evaluated the Optimized S-Scrum in industry by conducting interviews. The first-stage results showed that by integrating STPA (System-Theoretic Process Analysis) can ensure the safety during each sprint and enhance the safety of delivered products, while the agility of S-Scrum is slightly worse than the original Scrum. Six challenges have been explored: Management changes the team's priorities during an iteration; Disturbed safety-related communication; Non-functional requirements are determined too late; Insufficient upfront planning; Insufficient well-defined completion criteria; Excessive time to perform upfront planning. We investigated further the causalities and optimizations. The second-stage results revealed that the safety and agility have been improved after the optimizations. We have gained a positive assessment and suggestions from industry. The optimized S-Scrum is feasible for developing safety-critical systems concerning the capability to ensure safety and the acceptable agility in a student project. Further attempt is still needed in industrial projects.

description: We propose a new formula to explain circular velocity profiles of spiral galaxies obtained from the Starobinsky model in Palatini formalism. It is based on the assumption that the gravity can be described by two conformally related metrics: one of them is responsible for the measurement of distances, while the other so-called dark metric, is responsible for a geodesic equation and therefore can be used for the description of the velocity profile. The formula is tested against a subset of galaxies taken from the HI Nearby Galaxy Survey (THINGS).

description: Proximity zone fossils (PZFs) are ionization signatures around recently active galactic nuclei (AGN) where metal species in the circumgalactic medium remain over-ionized after the AGN has shut-off due to their long recombination timescales. We explore cosmological zoom hydrodynamic simulations using the EAGLE model paired with a non-equilibrium ionization and cooling module including time-variable AGN radiation to model PZFs around star-forming, disk galaxies in the z~0.2 Universe. Previous simulations typically under-estimated the O VI content of galactic haloes, but we show that plausible PZF models increase O VI column densities by 2-3x to achieve the levels observed around COS-Halos star-forming galaxies out to 150 kpc.
