description: A fully-sampled and hitherto highest resolution and sensitivity observation of neutral hydrogen (HI) in the Leo Triplet (NGC 3628, M 65/NGC 3623, and M 66/NGC 3627) reveals six HI structures beyond the three galaxies. We present detailed results of the morphologies and kinematics of these structures, which can be used for future simulations. In particular, we detect a two-arm structure in the plume of NGC 3628 for the first time, which can be explained by a tidal interaction model. The optical counterpart of the plume is mainly associated with the southern arm. The connecting part (base) of the plume (directed eastwards) with NGC 3628 is located at the blueshifted (western) side of NGC 3628. Two bases appear to be associated with the two arms of the plume. A clump with reversed velocity gradient (relative to the velocity gradient of M 66) and a newly detected tail, i.e. M 66SE, is found in the southeast of M 66. We suspect that M 66SE represents gas from NGC 3628 which was captured by M 66 in the recent interaction between the two galaxies. Meanwhile gas is falling toward M 66, resulting in features already previously observed in the southeastern part of M 66, e.g. large line widths and double peaks. An upside-down `Y'-shaped HI gas component (M 65S) is detected in the south of M 65 which suggests that M 65 may also have been involved in the interaction. We strongly encourage modern hydrodynamical simulations of this interacting group of galaxies to reveal the origin of the gaseous debris surrounding all three galaxies.

description: The title molecule, N-(4-Nitrobenzoyl)-S-(2-hydroxyethyl)-carbamodithioate, (C10H10N2O4S2), was synthesized and its structure verified by single crystal X-ray diffraction and FT-IR, 1H-NMR, 13C-NMR spectroscopic techniques. The molecular geometry and vibrational frequencies of the title compound in the ground state have been calculated by using the density functional theory (DFT) method with 6–311 G(d,p) basis set, and compared with the experimental data. The calculated results show that the optimized geometries can well reproduce the crystal structural parameters. A detailed vibrational spectral analysis has been carried out and assignments of observed fundamental bands have been proposed on basis of peak positions. The scaled theoretical frequencies show very good agreement with experimental values. Besides, a molecular electrostatic potential (MEP), frontier molecular orbitals (FMOs) analysis and thermodynamic properties of the title compound were investigated by theoretical calculations.

description: A reformulation of the Hoop Conjecture based on the concept of trapped circle is presented. The problems of severe compactness in every spatial direction, and of how to superpose the hoops with the surface of the black hole, are resolved. A new conjecture concerning "peeling" properties of dynamical/trapping horizons is propounded. A novel geometric Hoop inequality is put forward.

description: A bidirectional Ultra-Wideband (UWB) localization scheme is one of the three widely adopted design integration processes commonly used in time-based UWB positioning systems. The key property of bidirectional UWB localization is its ability to serve both navigation and tracking tasks within a single localization scheme on demand. Traditionally, navigation and tracking in wireless localization systems were treated as separate entities due to distinct applicable use-cases and methodological needs in each implementation process. Therefore, the ability to flexibly or elastically combine two unique positioning perspectives (navigation and tracking) within a single scheme can be regarded as a paradigm shift in the way location-based services are conventionally observed. This article reviews the mentioned bidirectional UWB localization from the perspective of a flexible and versatile positioning topology and highlights its potential in the field. In this regard, the article comprehensively describes the complete system model of the bidirectional UWB localization scheme using modular processes. It also discusses the demonstrative evaluation of two system integration processes and conducts a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis of the scheme. Furthermore, the prospect of the presented bidirectional localization scheme for achieving precise location estimation in 5G/6G wireless mobile networks, as well as in Wi-Fi fine-time measurement-based positioning systems was briefly discussed.

description: Graphene nanodisk is a graphene derivative with a closed edge. The trigonal zigzag nanodisk with size $N$ has $N$-fold degenerated zero-energy states. A nanodisk can be interpletted as a quantum dot with an internal degree of freedom. The grand state of nanodisk has been argued to be a quasi-ferromagnet, which is a ferromagnetic-like states with a finite but very long life time. We investigate the spin-filter effects in the system made of nanodisks and leads based on the master equation. The finite-size effect on spin filter is intriguing due to a reaction from the polarization of incoming current to a quasi-ferromagnet. Analyzing the relaxation process with the use of the Landau-Lifshitz-Gilbert equation, we explore the response to four types of incoming currents, namely, unpolarized current, perfectly polarized current, partially polarized current and pulse polarized current. We propose some applications for spintronics, such as spin memory, spin amplifier, spin valve, spin-field-effect transistor and spin diode.

Transition between the stick and slip states in a simplified model of magnetic friction

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

description: We introduce a simplified model of magnetic friction, and investigate its behavior using both numerical and analytical methods. When resistance coefficient $γ$ is large, the movement of the system obeys the thermally activated process. In contrast, when $γ$ is sufficiently small, the slip and stick states behave as separate metastable states, and the lattice velocity depends on the probability that the slip state appears. We evaluate the velocities in both cases using several approximations and compare the results with those of numerical simulations.

description: Using quiet-time measurements of element oxygen within the energy range 7.3--237.9 MeV nuc$^{-1}$ from the ACE spacecraft at 1 au, we compare the energy spectra and intensities of anomalous and Galactic cosmic rays (ACRs and GCRs, respectively) during 1997--2020. Our analysis shows that the transition from ACR-dominated spectrum to GCR-dominated spectrum occurs at energies $\sim$15 to $\sim$35 MeV nuc$^{-1}$, and the transition energy $E_t$ is found to be well anticorrelated with varying solar activity. This is the first study of ACR-GCR transition energy dependence on the solar cycle variation. At energies below $E_t$, the index of the power-law ACR-dominated spectrum ($γ_1$) ranges from -2.0 to -0.5, whereas the GCR-dominated spectrum has a power-law index ($γ_2$) changing from 0.3 to 0.8 at energies ranging from $E_t$ to 237.9 MeV nuc$^{-1}$. Both $γ_1$ and $γ_2$ are positively correlated with solar activity. In addition, during the solar cycle 24/25 minimum period, the peak GCR intensity observed by ACE spacecraft is about 8\% above its 2009 value, setting a new record since the space age, while the peak ACR intensity is almost similar to that of the previous two solar cycles with the same pattern of solar magnetic polarity, indicating a different modulation mechanism between ACRs and GCRs.

description: В статье проведен сравнительный анализ ответственности за насильственные хищения в уголовном праве ряда стран общего и континентального права. Показано отсутствие различий в квалификации ответственности за насильственные хищения в зависимости от характера насилия, во всех случаях деяние, при использовании насилия, квалифицируется как разбой. За исключением уголовного права Великобритании, где разбой понимается как материальный состав, в других странах насильственное хищение признается оконченным с момента нападения. Показано, что в странах общего права общественная опасность насильственных хищений связана, в первую очередь, посягательством на собственность, в странах континентального права она связана с угрозой личности. В российском уголовном праве общественная опасность насильственных хищений связана, в первую очередь, с посягательством на собственность, но, в зависимости от характера посягательства на личность как дополнительный объект, проводится разграничение между разбоем и грабежом. Такая дифференциация является особенностью российского уголовного права

Bridging the Transparency Gap: What Can Explainable AI Learn From the AI Act?

description: The European Union has proposed the Artificial Intelligence Act which introduces detailed requirements of transparency for AI systems. Many of these requirements can be addressed by the field of explainable AI (XAI), however, there is a fundamental difference between XAI and the Act regarding what transparency is. The Act views transparency as a means that supports wider values, such as accountability, human rights, and sustainable innovation. In contrast, XAI views transparency narrowly as an end in itself, focusing on explaining complex algorithmic properties without considering the socio-technical context. We call this difference the ``transparency gap''. Failing to address the transparency gap, XAI risks leaving a range of transparency issues unaddressed. To begin to bridge this gap, we overview and clarify the terminology of how XAI and European regulation -- the Act and the related General Data Protection Regulation (GDPR) -- view basic definitions of transparency. By comparing the disparate views of XAI and regulation, we arrive at four axes where practical work could bridge the transparency gap: defining the scope of transparency, clarifying the legal status of XAI, addressing issues with conformity assessment, and building explainability for datasets.

description: We derive two fundamental laws of chiral band crossings: (i) a local constraint relating the Chern number to phase jumps of rotation eigenvalues; and (ii) a global constraint determining the number of chiral crossings on rotation axes. Together with the fermion doubling theorem, these laws describe all conditions that a network of chiral band crossing must satisfy. We apply the fundamental laws to prove the existence of enforced double Weyl points, nodal planes, and generic Weyl points, among others. In addition, we show that chiral space-group symmetries cannot stabilize nodal lines with finite Chern numbers. Combining the local constraint with explicit low-energy models, we determine the generic topological phase diagrams of all multi-fold crossings. Remarkably, we find a four-fold crossing with Chern number 5, which exceeds the previously conceived maximum Chern number of 4. We identify BaAsPt as a suitable material with this four-fold crossing exhibiting Chern number 5 near the Fermi energy.

description: Recently a correspondence between non-propagating degrees of freedom in maximal supergravity and the very extended algebra E_11 has been found. We perform a similar analysis for a supergravity theory with eight supercharges and very extended G_2. In particular, in the context of d=5 minimal supergravity, we study whether supersymmetry can be realised on higher-rank tensors with no propagating degrees of freedom. We find that in this case the very extended algebra fails to capture these possibilities.

description: We report a resonant x-ray scattering (RXS) study of antiferromagnetic neptunium compounds NpCoGa_5 and NpRhGa_5 at the Np M_4 and Ga K-edges. Large resonant signals of magnetic dipole character are observed below the Neel temperatures at both edges. The signals at the Np edges confirm the behaviour determined previously from neutron diffraction, i.e. the moments along [001] in NpCoGa_{5} and in NpRhGa_5 a reorientation of the moments from the c-axis direction to the ab plane. In the latter material, on application of magnetic field of 9 Tesla along the [010] direction we observe a change in the population of different [110]-type domains. We observe also a magnetic dipole signal at the Ga K-edge, similarly to the reported UGa_3 case, that can be interpreted within a semi-localized model as an orbital polarization of the Ga 4p states induced via strong hybridization with the Np 5f valence band. Quantitative analysis of the signal shows that the Ga dipole on the two different Ga sites follows closely the Np magnetic moment reorientation in NpRhGa_5. The ratios of the signals on the two inequivalent Ga sites are not the same for the different compounds.

description: First order phase transitions are ubiquitous in nature, however, this notion is ambiguous and highly debated in the case of quantum systems out of thermal equilibrium. We construct a paradigmatic example which allows for elucidating the key concepts. We show that atoms in an optical cavity can manifest a first-order dissipative phase transition where the stable co-existing phases are quantum states with high quantum purity. These states include hyperfine ground states of atoms and coherent states of electromagnetic field modes. The scheme benefits from the collective enhancement of the coupling between the atoms and the cavity field. Thereby we propose a readily feasible experimental scheme to study the dissipative phase transition phenomenology in the quantum limit, allowing for, in particular, performing a finite-size scaling to the thermodynamic limit.
Sub-- and super--fidelity as bounds for quantum fidelity

description: We derive several bounds on fidelity between quantum states. In particular we show that fidelity is bounded from above by a simple to compute quantity we call super--fidelity. It is analogous to another quantity called sub--fidelity. For any two states of a two--dimensional quantum system (N=2) all three quantities coincide. We demonstrate that sub-- and super--fidelity are concave functions. We also show that super--fidelity is super--multiplicative while sub--fidelity is sub--multiplicative and design feasible schemes to measure these quantities in an experiment. Super--fidelity can be used to define a distance between quantum states. With respect to this metric the set of quantum states forms a part of a $N^2-1$ dimensional hypersphere.

description: By searching the Open Supernova Catalog, an extra-galactic transient host galaxy database, and literature analyses, I present the largest sample of type Ia supernova (SN Ia) siblings to date. The sample comprises 158 galaxies, consisting of 327 confirmed SNe Ia - over 10 times larger than existing sibling SN Ia samples. SN siblings share host galaxies, and thus share global environmental properties and associated systematic uncertainties. This makes them valuable for both cosmological and astrophysical analyses; for example, sibling SNe Ia allow for comparison of environmental properties within the same galaxy, progenitor comparisons, rates analyses, and multiple calibrations of the Hubble-Lema\^ıtre constant. This large sample will provide a variety of new avenues of research, and be of great interest to the wider SN Ia community. To give an example use of this sample, I define a cosmology sub-sample of 44 siblings; and use it to compare light-curve properties between sibling pairs. I find no evidence for correlations in stretch ($x_1$) and colour ($c$) between pairs of siblings. Moreover, by comparing to a comparable set of random pairs of SNe Ia through boot-strapping, I find that siblings are no more similar in $x_1$ and $c$ than any random pair of SNe Ia. Given that siblings share the same hosts, differences in $x_1$ and $c$ between siblings cannot be due to global galaxy properties. This raises important questions regarding environmental systematics for SN Ia standardisation in cosmology, and motivates future analyses of sibling SNe Ia.

description: We critically discuss recent articles by S. Hoffmann and N. Vogt on historical novae and supernovae (SNe) as well as their list of `24 most promising events' `with rather high probability to be a nova' (Hoffmann et al. 2020). Their alleged positional accuracy of previously suggested historical nova/SN records is based on inhomogeneous datasets (Vogt et al. 2019), but then used for the nova search in Hoffmann et al. (2020). Their claim that previously only `point coordinates' for nova/SN candidates were published, is fabricated. Their estimate of expected nova detection rates is off by a factor of 10 due to miscalculation. They accept counterparts down to 4 to 7 mag at peak, which is against the consensus for the typical limit of naked-eye discovery. When they discuss previously suggested identifications of historical novae, which they all doubt, they do not present new facts (Hoffmann 2019). Their catalog of `24 most promising events' for novae (Hoffmann et al. 2020) neglects important recent literature (e.g. Pankenier et al. 2008 and Stephenson and Green 2009), the claimed methods are not followed, etc. At least half of their short-list candidates were and are to be considered comets. For many of the others, duration of more than one night and/or a precise position is missing and/or the sources were treated mistakenly. Two highlights, a fabricated SN AD 667/668 and a presumable recurrent nova in AD 891, are already rejected in detail in Neuhaeuser et al. (2021); in both cases, all evidence speaks in favor of comets. There remains only one reliable case, where close to one (possible) historically reported position, a nova shell was already found (AD 1437, Shara et al. 2017). Follow-up observations cannot be recommended.

description: Deep learning techniques have dominated the literature on aspect-based sentiment analysis (ABSA), achieving state-of-the-art performance. However, deep models generally suffer from spurious correlations between input features and output labels, which hurts the robustness and generalization capability by a large margin. In this paper, we propose to reduce spurious correlations for ABSA, via a novel Contrastive Variational Information Bottleneck framework (called CVIB). The proposed CVIB framework is composed of an original network and a self-pruned network, and these two networks are optimized simultaneously via contrastive learning. Concretely, we employ the Variational Information Bottleneck (VIB) principle to learn an informative and compressed network (self-pruned network) from the original network, which discards the superfluous patterns or spurious correlations between input features and prediction labels. Then, self-pruning contrastive learning is devised to pull together semantically similar positive pairs and push away dissimilar pairs, where the representations of the anchor learned by the original and self-pruned networks respectively are regarded as a positive pair while the representations of two different sentences within a mini-batch are treated as a negative pair. To verify the effectiveness of our CVIB method, we conduct extensive experiments on five benchmark ABSA datasets and the experimental results show that our approach achieves better performance than the strong competitors in terms of overall prediction performance, robustness, and generalization.

The conditions for quantum violation of macroscopic realism
Creators: name: Kofler, Johannes

Publisher: name: arXiv
Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Why do we not experience a violation of macroscopic realism in every-day life? Normally, no violation can be seen either because of decoherence or the restriction of coarse-grained measurements, transforming the time evolution of any quantum state into a classical time evolution of a statistical mixture. We find the sufficient condition for these classical evolutions for spin systems under coarse-grained measurements. Then we demonstrate that there exist "non-classical" Hamiltonians whose time evolution cannot be understood classically, although at every instant of time the quantum spin state appears as a classical mixture. We suggest that such Hamiltonians are unlikely to be realized in nature because of their high computational complexity.

Profiles of Social Anxiety Symptoms and Impulsivity in College Students

Subjects: subject: Clinical psychology
subject: externalizing
subject: impulsivity
subject: internalizing
subject: social anxiety

description: Prior work points to a subtype of Social Anxiety (SA) characterized by disinhibition or high externalizing behaviors (e.g., substance use and Attention Deficit Hyperactivity Disorder (ADHD) symptoms). This study extended prior work by replicating subtypes of SA and impulsivity and examining differences among these subtypes in their expression of externalizing behavior. Three hundred seventy-five undergraduates completed an online study including measures of SA, substance use, ADHD symptoms and impulsivity. Latent class analyses revealed three classes of individuals who were: (a) low SA and low impulsivity, (b) high SA and low impulsivity, and (c) high SA and high impulsivity. Individuals high in both SA and impulsivity exhibited greater likelihoods of exhibiting externalizing behavior concerns, relative to the two other classes, with the largest differences on ADHD symptoms. These findings indicate that identifying differences among SA subtypes in externalizing behavior concerns depends on the externalizing domain.

description: A cosmic string wake produces a distinct non-Gaussian signal in 21-cm intensity maps at redshifts above that of reionization. While the string signal is (locally) larger in amplitude than the signal of the Gaussian fluctuations of the $Λ$CDM model, they are overwhelmed (even locally in position space) by astrophysical and instrumental foregrounds. Here, we study to what extent the signal can be extracted from noisy interferometric data. The narrowness of the string-induced feature in redshift direction allows for a subtraction of astrophysical and instrumental foregrounds. Based on the specific geometry of the string signal we identify a particular three-point statistic which is promising in order to extract the signal, and we find that, having in mind a telescope of specifications similar to that of the MWA instrument, the string signal can be successfully extracted for a value of the string tension of $Gμ= 3 \times 10^{-7}$. Prospects for further improvements of the analysis are discussed.

A DECISION MODEL FOR STUDENT-ATHLETE ENTRY INTO THE NBA DRAFT

description: We develop a Markov Decision Process model using the framework of an optimal stopping problem to describe whether or not a student-athlete should enter the National Basketball Association (NBA) draft early. Our model uses a simulation algorithm for estimating the draft value of a student-athlete to inform his decision as he evaluates whether or not he should enter the NBA draft and forgo his remaining college eligibility. The model incorporates the shift in player evaluation for the draft that is now heavily focused on a student athlete's potential rather than the talent that a student-athlete displays in the collegiate game. The algorithm generates two estimates, one biased high and one biased low, both asymptotically unbiased as the computational effort increases and converging to the student-athlete's draft value.

description: Stricter aviation emissions regulations have led to the desire
for lean-premixed-vaporized combustors over rich-quench-lean
burners. While this operation mode is beneficial for reducing
NOx and particulate emissions, the interaction of the flame
and hot exhaust gases with the cooling flow results in increased
CO emissions. Predicting CO in computational fluid dynamics
(CFD) simulations remains challenging. To assess current
model performance under practically relevant conditions, Large-
Eddy Simulation (LES) of a lab-scale effusion cooling test rig is
performed. Flamelet-based manifolds, in combination with the
Artificial Thickened Flame (ATF) approach, are utilized to model
the Turbulence-Chemistry Interaction (TCI) in the test-rig with
detailed chemical kinetics at reduced computational costs. Heat
losses are considered via exhaust gas recirculation (EGR). Local
transport effects in CO emissions are included through an additional
transport equation. Additionally, a Conjugate Heat Transfer
(CHT) simulation is performed for good estimations of the
thermal boundary conditions. Extensive validation of this comprehensive
model is conducted using the available experimental
dataset for the studied configuration. Subsequently, model sensitivities
for predicting CO are assessed, including the progress
variable definition and the formulation of the CO source term in
the corresponding transport equation. To investigate the flame
thickening influence in the calculated CO, an ATF-postprocessing
correction is further developed. Integrating multiple sophisticated
pollutant submodels and evaluating their sensitivity offers insights for future investigations into modeling CO emissions in
aero-engines and stationary gas turbines.
Essays on the qualitative theory of forest economics
Creators: name: Heaps, Terry
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with questions relating to the optimal regulation of logging in a solely owned forest. Optimal is taken to mean maximizing the present value of net revenues obtainable from growing and harvesting an infinite sequence of crops on a piece of forest land. Discussions of optimal harvesting usually assume there is no advantage to changing the age distribution of a forest. This is also the assumption of Chapter I. In this case, trees are cut when their age reaches the rotation period which is determined from what is called the Faustmann formula. Chapter I looks at the comparative statics of these rotation periods. The effect of a change in an exogenous parameter on the rotation period is shown to depend on how certain elasticities are changed. It is then shown that there are conditions under which these results extend to a more complex forestry model where the manager chooses the level of effort to be expended on regeneration and silvicultural activities. The techniques used are drawn from optimal control theory. Chapter II introduces considerations which may make it advantageous to alter the age structure of a forest while logging it. In particular, a variable average cost of harvesting function is allowed for. A forestry maximum principle is derived which determines the dynamics of optimal harvesting. This is similar to the maximum principle for processes incorporating a delay (the time between planting and harvesting). The usual growth theory questions are then asked. In the variable average cost case, the "steady state" age distributions turn out to be "normal" forests with the time between harvests being determined by a Faustmann formula Global asymptotic stability is not proven but is shown to be likely. Finally, Chapter III applies the forestry maximum principle to a problem of determining an optimal harvesting policy for a group of forests subject to a sustained yield constraint. Assuming stability and with a few additional restrictions, it is shown that the optimal long run policy is to convert each separate forest to a "normal" forest. The Faustmann formula determines the number of age classes in each forest.
