description: Inorganic electrides are a new class of compounds catering to the interest of scientists due to the multiple usages exhibited by interstitial electrons in the lattice. However, the influence of the shape and distribution of interstitial electrons on physical properties and new forms of physical states are still unknown. In this work, crystal structure search algorithms are employed to explore the possibility of forming new electrides in the As-Li system, where interstitial electrons behave as 1D electron chains (1D electride) in Pmmm phase of AsLi$_7$ and transform into 0D electron clusters (0D electride) in P6/mmm phase at 80 GPa. The P6/mmm phase has relatively high superconductivity at 150 GPa (Tc=38.4K) than classical electrides, even at moderate pressure with Tc=16.6K. The novel superconducting properties are conjectured to be possibly due to three Van Hove singularities at the Fermi level. In addition, a Dirac cone in the band has been observed, expanding the sources of Dirac materials. The survival of AsLi$_7$ at room temperature is confirmed by molecular dynamics simulation at 300 K. At 1000 K, the As atoms in the system act like solid, while a portion of the Li atoms cycle around the As atoms, and another portion of the Li atoms flow freely like liquid, showing the novel physical phenomenon of the coexistence of the plastic and superionic states. This suggests that the superionic and plastic states cannot only be found in hydrides but also in the electride. Our results indicate that superconducting electride AsLi$_7$ with superionic and plastic states can exist in Earth's interior.

description: The electronic structure of the $f$-based superconductor $\mathrm{CeIr_3}$ was studied by photoelectron spectroscopy. The energy distribution of the $\mathrm{Ce}~4f$ states were revealed by the $\mathrm{Ce}~3d-4f$ resonant photoelectron spectroscopy. The $\mathrm{Ce}~4f$ states were mostly distributed in the vicinity of the Fermi energy, suggesting the itinerant character of the $\mathrm{Ce}~4f$ states. The contribution of the $\mathrm{Ce}~4f$ states to the density of states (DOS) at the Fermi energy was estimated to be nearly half of that of the $\mathrm{Ir}~5d$ states, implying that the $\mathrm{Ce}~4f$ states have a considerable contribution to the DOS at the Fermi energy. The $\mathrm{Ce}~3d$ core-level and $\mathrm{Ce}~3d$ X-ray absorption spectra were analyzed based on a single-impurity Anderson model. The number of the $\mathrm{Ce}~4f$ states in the ground state was estimated to be $0.8-0.9$, which is much larger than the values obtained in the previous studies (i.e., $0-0.4$).

description: We have successfully synthesized three quasi-2D geometrically frustrated magnetic compounds (α-MCr_2O_4, M=Ca, Sr, Ba) using the spark-plasma-sintering technique. All these members of the α-MCr_2O_4 family consist of the stacking planar triangular lattices of Cr$^{3+}$ spins (${\rm S}=3/2$), separated by non-magnetic alkaline earth ions. Their corresponding magnetic susceptibility, specific heat, dielectric permittivity and ferroelectric polarization are systematically investigated. A long-range magnetic ordering arises below the Néel temperature (around 40K) in each member of the α-MCr_2O_4 family, which changes to the quasi-120\degree proper-screw-type helical spin structure at low temperature. A very small but confirmed spontaneous electric polarization emerges concomitantly with this magnetic ordering. The direction of electric polarization is found within the basal triangular plane. The multiferroicity in α-MCr_2O_4 can not be explained within the frameworks of the magnetic exchange striction or the inverse Dzyaloshinskii-Moriya interaction. The observed results are more compatible with the newly proposed Arima mechanism that is associated the d-p hybridization between the ligand and transition metal ions, modified by the spin-orbit coupling. The evolution of multiferroic properties with the increasing inter-planar spacing (as M changes from Ca to Ba) reveals the importance of interlayer interaction in this new family of frustrated magnetic systems.

description: Introduction
In western countries, it is estimated that one to two people per 100 adults have heart failure. In Latin America, and particularly in Ecuador, few studies have assessed survival in this disease. For this reason, this study aimed to determine survival and prognostic factors based on clinical and socio-demographic characteristics.Methods
We did a single-center study of survival analysis in 228 patients with heart failure between 2015 and 2019. Survival analysis was done by the actuarial method and a multivariate Cox regression analysis.Results
Overall survival at the first year was 86% and at five years was 46%. Heart failure etiology (hazard ratio, 1.162: 95% confidence interval, 1.001 to 1.349; P = 0.049), ethnicity (1.415; 10.1 to 199; P = 0.043), age (1.035; 1.011 to 1.06; P = 0.04) and altered values of basal creatinine (1.21; 1.002 to 1.461; P = 0.048) were associated with worse prognosis.Conclusions
Global survival time was similar to other international studies. Etiology, ethnicity, creatinine values, and age were factors associated with a worse vital prognosis.
title: A comparison of benthic macroinvertebrate assemblages among kryal and rhithral lake outlets in the North Cascade Mountains

description:
This study compares the physico-chemical conditions and composition of benthic macroinvertebrates from five rhithral (snowmelt-fed) and five kryal (glacially-fed) lake outlet streams in the North Cascade Mountains, WA. Non-metric, non-parametric cluster and association analysis (NMCAA) clearly separated outlet streams of kryal and rhithral origin based on physico-chemical and taxon variables. Kryal lake outlets were characterized by lower water temperatures, unstable in-stream channels and higher turbidity, discharge and fine substrates than rhithral sites. A total of 24,985 specimens representing 93 macroinvertebrate taxa were collected. Rhithral lake outlets had significantly higher densities and supported more taxa than kryal sites (9,049 ind./m2 and 77 taxa versus 821 ind./m2 and 35 taxa). Chironomidae were the dominant taxon amongst all sites, although densities and taxa richness were one-third in the kryal lake outlets when compared to rhithral sites. Rhithral lake outlets contained higher densities of non-insect taxa such as Acari, Oligochaeta, Nemathelminthes, Planariidae and crustaceans. Water temperature, stream discharge and turbidity were the variables most strongly correlated to density and taxa richness. My results suggest that glacial presence was the dominant factor influencing instream environmental conditions and subsequently macroinvertebrate assemblages of alpine lake outlet streams.

description: We develop a framework of "semi-automatic differentiation" that combines existing gradient-based methods of quantum optimal control with automatic differentiation. The approach allows to optimize practically any computable functional and is implemented in two open source Julia packages, GRAPE.jl and Krotov.jl, part of the QuantumControl.jl framework. Our method is based on formally rewriting the optimization functional in terms of propagated states, overlaps with target states, or quantum gates. An analytical application of the chain rule then allows to separate the time propagation and the evaluation of the functional when calculating the gradient. The former can be evaluated with great efficiency via a modified GRAPE scheme. The latter is evaluated with automatic differentiation, but with a profoundly reduced complexity compared to the time propagation. Thus, our approach eliminates the prohibitive memory and runtime overhead normally associated with automatic differentiation and facilitates further advancement in quantum control by enabling the direct optimization of non-analytic functionals for quantum information and quantum metrology, especially in open quantum systems. We illustrate and benchmark the use of semi-automatic differentiation for the optimization of perfectly entangling quantum gates on superconducting qubits coupled via a shared transmission line. This includes the first direct optimization of the non-analytic gate concurrence.

description: The layered delafossite compound AgNiO$_2$ with $2H$ stacking symmetry undergoes a structural metal-to-metal transition at $T_{\rm S}\sim 365$ K. It has been described in the past as a charge-ordering transition, where local $S=1$ spins are formed on part of the Ni sites. By means of first-principles many body calculations, we show that the transition is in fact a site-selective Mott transition on the Ni sublattice with only minor charge differentiation. Key to this finding is the uncovering of ligand-hole physics, rendering a Ni$^{2+}$ instead of a formal Ni$^{3+}$ oxidation state, in conjunction with strong local Coulomb repulsions.

description: We investigate the notion of finite time stability for tempered fractional systems (TFSs) with time delays and variable coefficients. Then, we examine some sufficient conditions that allow concluding the TFSs stability in a finite time interval, which include the nonhomogeneous and the homogeneous delayed cases. We present two different approaches. The first one is based on Hölder's and Jensen's inequalities, while the second one concerns the Bellman--Grönwall method using the tempered Grönwall inequality. Finally, we provide two numerical examples to show the practicability of the developed procedures.

description: Accents, as variations from standard pronunciation, pose significant challenges for speech recognition systems. Although joint automatic speech recognition (ASR) and accent recognition (AR) training has been proven effective in handling multi-accent scenarios, current multi-task ASR-AR approaches overlook the granularity differences between tasks. Fine-grained units capture pronunciation-related accent characteristics, while coarse-grained units are better for learning linguistic information. Moreover, an explicit interaction of two tasks can also provide complementary information and improve the performance of each other, but it is rarely used by existing approaches. In this paper, we propose a novel Decoupling and Interacting Multi-task Network (DIMNet) for joint speech and accent recognition, which is comprised of a connectionist temporal classification (CTC) branch, an AR branch, an ASR branch, and a bottom feature encoder. Specifically, AR and ASR are first decoupled by separated branches and two-granular modeling units to learn task-specific representations. The AR branch is from our previously proposed linguistic-acoustic bimodal AR model and the ASR branch is an encoder-decoder based Conformer model. Then, for the task interaction, the CTC branch provides aligned text for the AR task, while accent embeddings extracted from our AR model are incorporated into the ASR branch's encoder and decoder. Finally, during ASR inference, a cross-granular rescoring method is introduced to fuse the complementary information from the CTC and attention decoder after the decoupling. Our experiments on English and Chinese datasets demonstrate the effectiveness of the proposed model, which achieves 21.45%/28.53% AR accuracy relative improvement and 32.33%/14.55% ASR error rate relative reduction over a published standard baseline, respectively.

description: In people with stroke, spinal cord injury, multiple sclerosis, and other upper motorneuron lesions, ankle clonus and quadriceps spasms may limit self-care and mobility tasks. The ankle clonus drop test, which measures the plantar flexor reflex threshold angle (PFRTA), and the pendulum test, which measures the quadriceps reflex threshold angle (QRTA), provide valid and reproducible measurements of ankle clonus and quadriceps hyperreflexia. However, measuring the PFRTA and QRTA requires high fidelity motion capture systems that are limited to laboratory settings by cost and complexity. The aim of this study was to evaluate a simple, single-camera based method of measuring ankle clonus and quadriceps spasticity in clinical settings. With synchronous 3-D inertial motion capture to provide a high fidelity reference, we used a smartphone camera and green stickers to measure the PFRTA and QRTA of 14 individuals with ankle clonus or quadriceps hyperreflexia in one or both legs. This resulted in test sessions on 22 impaired legs with four repetitions of each test on each leg conducted by a student physical therapist and an experienced physical therapist. We hypothesized that the smartphone camera measurements would provide clinically useful outcome measures for assessing ankle clonus and quadriceps spasticity. To assess accuracy of the camera-measurements, we computed the bias and limits of agreement between the camera and the inertial motion capture measurements. For reliability, we computed intra-rater and inter-sensor reliability coefficients in addition to the minimum detectable change. The smartphone PFRTA biases were smaller than 0.2° and the QRTA biases smaller than 1.2°. The limits of agreement for the PFRTA were ±4.66°/ ±7.49° (student/expert), and for the QRTA were ±4.40°/±4.67°. Reliability was similar between the camera and inertial measurements of tests by both rater types: intra-rater reliability ranged from 0.85-0.90 for the PFRTA and ranged from 0.96-0.98 for the QRTA. The inter-sensor reliability when measuring the PFRTA and QRTA was 0.97 and 0.99. The minimum detectable change for the PFRTA ranged from 7.10°-8.70°, while for the QRTA ranged from 7.65°-8.27°. Based on prior research, the limits of agreement and minimum detectable change were sufficiently low for purposes of interindividual, repeatable measurement. These data show that student and experienced physical therapists using ubiquitous existing hardware such as a smartphone can produce accurate, reliable assessments of ankle clonus and quadriceps hyperreflexia in a clinical environment.
Topological Interference Management through Index Coding

description: This work studies linear interference networks, both wired and wireless, with no channel state information at the transmitters (CSIT) except a coarse knowledge of the end-to-end one-hop topology of the network that only allows a distinction between weak (zero) and significant (non-zero) channels and no further knowledge of the channel coefficients' realizations. The network capacity (wired) and DoF (wireless) are found to be bounded above by the capacity of an index coding problem for which the antidote graph is the complement of the given interference graph. The problems are shown to be equivalent under linear solutions. An interference alignment perspective is then used to translate the existing index coding solutions into the wired network capacity and wireless network DoF solutions, as well as to find new and unified solutions to different classes of all three problems.

description: Topological superconductors have long been sought for their potential use in quantum computing. The type-II Weyl semimetal MoTe$_{2}$ is an obvious candidate, exhibiting a superconducting state below 500 mK at ambient pressure, but the question remains whether the pairing is conventional $s^{++}$ or topological $s^{+-}$. The application of external pressure favors the superconducting state in MoTe$_{2}$ and suppresses the structural transition from $1T'$ to $T_{d}$. The competition between the two structures leads to a mixed phase that strongly enhances the disorder present in the system, remarkably without affecting the superconducting transition temperature, in contrast to the expectation of $s^{+-}$ pairing superconductivity. Our thorough analysis of the electrical and Hall resistivities as a function of pressure yields the most accurate temperature-pressure phase diagram available to date for MoTe$_{2}$ and a detailed view of the relationship between disorder and superconductivity, supporting a conventional $s^{++}$ pairing symmetry.

description: The subtle interplay of band topology and symmetry broken phase, induced by electron correlations, has immense contemporary relevance and potentially offers novel physical insights. Here, we demonstrate charge density wave (CDW) in bulk Y$_2$Ir$_2$O$_7$ for T < 10 K, and its transition to the Weyl semimetal (WSM) phase at higher temperatures. The CDW phase is evidenced by a) current induced nonlinear conductivity with negative differential resistance at low temperature, b) low frequency Debye like dielectric relaxation at low temperature with a large dielectric constant, and c) an anomaly in the temperature dependence of the thermal expansion coefficient. The WSM phase at higher temperature is confirmed by the DC and AC transport measurements which show an inductive response at low frequencies. More interestingly, we show that by reducing the crystallite size, the low temperature CDW phase can be eliminated leading to the restoration of the WSM phase.

description: Постановка проблемы. Оценка эффективности лучевой терапии не может быть полной без учета ситуации самих пациентов. То, как человек реагирует на назначение лучевой терапии, в каком состоянии находится перед ней, что знает о ней, побочных эффектах, последствиях, и чего опасается – также может влиять как на эффективность терапии, так и на связанные с ней риски. Радиологические факторы риска при лучевой терапии могут быть связаны с увеличением дозовой нагрузки, в первую очередь, от неучтенной дозовой нагрузки, вызываемой потоками вторичных частиц. Психологические факторы во многом связаны с субъективным отношением к лучевой терапии, тревогой о здоровье и благополучии пациентов, что требует диагностики этого отношения и возможной психологической коррекции.

Цель. Исследовать взаимосвязь радиологических (дозы излучения, полученной пациентами) и психологических (ожиданий, представлений о лечении) факторов эффективности лучевой терапии при назначении таковой пациентам с онкологическими заболеваниями.

Результаты. Полученные результаты позволяют дать следующие рекомендации по повышению эффективности лучевой терапии для минимизации радиологических рисков: 1) в связи с опасностью дополнительного вклада дозы от быстрых нейтронов в дозу, получаемую пациентом при лучевой терапии, рекомендуется планировать лучевую терапию при энергиях ниже 10 , причем минимизировать использование компенсаторов, внешних клиньев и блоков ускорителя; 2) рекомендовать производителям минимизировать использование материалов с высоким сечением активации фотонов и нейтронов при изготовлении компонентов ускорителя и его аксессуаров; 3) возвращать блоки ускорительного комплекса в исходное положение, а в программу гарантии качества лучевой терапии включить измерение дозы нейтронов; 4) шире использовать портативные радиационные мониторы для оценки дозы при работе линейных медицинских ускорителей с тормозным излучением 10…24 МэВ.

Практическая значимость. Дальнейшие исследования должны быть направлены на расширение выборок и оценку различных социодемографических факторов отношения к лучевой терапии, а также на изучение прогностического значения отношения к лучевой терапии у пациентов с онкологическими заболеваниями.

description: The Philippine aquaculture sector is primarily dominated by milkfish, with the province of Iloilo as one of the key producing areas. However, the production in the province has exhibited a decreasing trend since 2011. In this light, this study is undertaken to determine the technical efficiency of milkfish production in the province of Iloilo and identify the factors that significantly affect such efficiency. Utilizing the maximum likelihood estimation method, a Cobb-Douglas production function was specified to estimate farm-level efficiency using the data from 181 milkfish producers interviewed. The technical efficiency scores ranged between 12.38% to 90.00%, with a mean of 59.16%. Efficiency was negatively affected by the length of culture, while the source of stocking material, pond tenure status, and frequency of stock checking positively contributed to efficiency. The results of this study emphasized potential areas where the production efficiency of milkfish can be further improved.

description: We present observations and an interpretative model of the dust environment of Main-Belt Comet P/2010 F5 (Gibbs). The narrow dust trails observed can be interpreted unequivocally as an impulsive event that took place around 2011 July 1st with an uncertainty of $\pm$10 days, and a duration of less than a day, possibly of the order of a few hours. The best Monte Carlo dust model fits to the observed trail brightness imply ejection velocities in the range 8-10 cm s$^{-1}$ for particle sizes between 30 cm and 130 $μ$m. This weak dependence of velocity on size contrasts with that expected from ice sublimation, and agrees with that found recently for (596) Scheila, a likely impacted asteroid. The particles seen in the trail are found to follow a power-law size distribution of index $\approx$-3.7. Assuming that the slowest particles were ejected at the escape velocity of the nucleus, its size is constrained to about 200-300 m in diameter. The total ejected dust mass is $\gtrsim 5\times 10^8$ kg, with represents approximately 4 to 20% of the nucleus mass.

description: We study the invisible Majorana fermions of $χ$ in bottomed baryon decays with flavor-changing neutral currents (FCNCs) based on the model-independent effective Lagrangian between the quarks and invisible particles. From the bounds of the coupling constants extracted from the experiments, we examine the decay branching ratios of $Λ_b\toΛχχ$, $Ξ_b^{0(-)}\toΞ^{0(-)}χχ$, $Λ_b\to n χχ$, $Ξ_b^{-}\to Σ^{-} χχ$, $Ξ_b^{0}\to Σ^{0} χχ$, and $Ξ_b^{0}\to Λχχ$, which can be as large as $6.3,~9.2,~5.7,~5.8,~2.7$, and $1.0\times10^{-5}$ for $m_χ=2$ GeV, respectively. Some of these decays are accessible to the future experimental searches, such as Belle II.

description: Since the 1950s, citation number or “impact” has been the dominant metric by which science is quantitatively evaluated. But research contributions play distinct roles in the unfolding drama of scientific debate, agreement and advance, which are differentially valued by scientists and their institutions. Computational power, access to citation data and an array of modeling techniques have given rise to a widening portfolio of metrics that extract different signals regarding their contribution to scientific activities. Besides impact, the innovation of work and the way that it builds up the scientific discussions are taken into consideration. Here we unpacks the complex, temporally evolving relationship between citation impact alongside novelty and disruption, two emerging measures that capture the degree to which science not only influences, but transforms later work. Novelty is measured at the point of production and captures how research draws upon unusual combinations of prior work. Disruption is measured over time and captures how research comes to eclipse or amplify the prior work on which it builds. We theorize that novel papers will exhibit disruptive impact over time, and demonstrate how they are much more likely than conventional papers to disrupt current literature. Novel papers do not do so immediately, but often become “sleeping beauties”, accumulating surprising attention and citation impact over the long run. In summary, new directions for science are created from a lack of consensus. Finally, we show how novelty can be reformulated as the combination of ideas across knowledge space to reveal the combinatorial nature of advance. The evolution of knowledge space over time characterizes how yesterday’s novelty forms today’s scientific conventions, which condition the novelty—and surprise—of tomorrow’s breakthroughs.

description: The accurate numerical solution of partial differential equations is a central task in numerical analysis allowing to model a wide range of natural phenomena by employing specialized solvers depending on the scenario of application. Here, we develop a variational approach for solving partial differential equations governing the evolution of high dimensional probability distributions. Our approach naturally works on the unbounded continuous domain and encodes the full probability density function through its variational parameters, which are adapted dynamically during the evolution to optimally reflect the dynamics of the density. For the considered benchmark cases we observe excellent agreement with numerical solutions as well as analytical solutions in regimes inaccessible to traditional computational approaches.

Nature of 4FGL J1838.2+3223: a flaring `spider' pulsar candidate

description: An unidentified $γ$-ray source 4FGL J1838.2+3223 has been proposed as a pulsar candidate. We present optical time-series multi-band photometry of its likely optical companion obtained with the 2.1-m telescope of Observatorio Astronómico Nacional San Pedro Mártir, Mexico. The observations and the data from the Zwicky Transient Facility revealed the source brightness variability with a period of $\approx$4.02 h likely associated with the orbital motion of the binary system. The folded light curves have a single sine-like peak per period with an amplitude of about three magnitude accompanied by fast sporadic flares up to one magnitude level. We reproduce them modelling the companion heating by the pulsar. As a result, the companion side facing the pulsar is strongly heated up to 11300$\pm$400 K, while the temperature of its back side is only 2300$\pm$700 K. It has a mass of 0.10$\pm$0.05 ${\rm M}_\odot$ and underfills its Roche lobe with a filling factor of $0.60^{+0.10}_{-0.06}$. This implies that 4FGL J1838.2+3223 likely belongs to the `spider' pulsar family. The estimated distance of $\approx$3.1 kpc is compatible with Gaia results. We detect a flare from the source in X-rays and ultraviolet using Swift archival data and another one in X-rays with the eROSITA all-sky survey. Both flares have X-ray luminosity of $\sim$10$^{34}$ erg s$^{-1}$ which is two orders of magnitude higher than the upper limit in quiescence obtained from eROSITA assuming spectral shape typical for spider pulsars. If the spider interpretation is correct, these flares are among the strongest flares observed from non-accreting spider pulsars.

description: Current research on users` perspectives of cyber security and privacy related to traditional and smart devices at home is very active, but the focus is often more on specific modern devices such as mobile and smart IoT devices in a home context. In addition, most were based on smaller-scale empirical studies such as online surveys and interviews. We endeavour to fill these research gaps by conducting a larger-scale study based on a real-world dataset of 413,985 tweets posted by non-expert users on Twitter in six months of three consecutive years (January and February in 2019, 2020 and 2021). Two machine learning-based classifiers were developed to identify the 413,985 tweets. We analysed this dataset to understand non-expert users` cyber security and privacy perspectives, including the yearly trend and the impact of the COVID-19 pandemic. We applied topic modelling, sentiment analysis and qualitative analysis of selected tweets in the dataset, leading to various interesting findings. For instance, we observed a 54% increase in non-expert users` tweets on cyber security and/or privacy related topics in 2021, compared to before the start of global COVID-19 lockdowns (January 2019 to February 2020). We also observed an increased level of help-seeking tweets during the COVID-19 pandemic. Our analysis revealed a diverse range of topics discussed by non-expert users across the three years, including VPNs, Wi-Fi, smartphones, laptops, smart home devices, financial security, and security and privacy issues involving different stakeholders. Overall negative sentiment was observed across almost all topics non-expert users discussed on Twitter in all the three years. Our results confirm the multi-faceted nature of non-expert users` perspectives on cyber security and privacy and call for more holistic, comprehensive and nuanced research on different facets of such perspectives.

Clumping in the inner winds of hot, massive stars from hydrodynamical line-driven instability simulations

description: We investigate the effects of stellar limb-darkening and photospheric perturbations for the onset of wind structure arising from the strong, intrinsic line-deshadowing instability (LDI) of a line-driven stellar wind. A linear perturbation analysis shows that including limb-darkening reduces the stabilizing effect of the diffuse radiation, leading to a net instability growth rate even at the wind base. Numerical radiation-hydrodynamics simulations of the non-linear evolution of this instability then show that, in comparison with previous models assuming a uniformly bright star without base perturbations, wind structure now develops much closer ($r \la 1.1 R_\star$) to the photosphere. This is in much better agreement with observations of O-type stars, which typically indicate the presence of strong clumping quite near the wind base.

description: We propose a model of Dark Supersymmetry, where a supersymmetric dark sector is coupled to the classically scale invariant non-supersymmetric Standard Model through the Higgs portal. The dark sector contains a mass scale that is protected against radiative corrections by supersymmetry, and the portal coupling mediates this scale to the Standard Model, resulting in a vacuum expectation value for the Higgs field and the usual electroweak symmetry breaking mechanism. The supersymmetric dark sector contains dark matter candidates, and we show that the observed dark matter abundance is generated for a natural choice of parameters, while avoiding the current experimental bounds on direct detection. Future experiments can probe this scenario if the dark sector mass scale is not too high.

description: Deep Neural Networks (DNNs) have shown excellent performance in a wide range of machine learning applications. Knowing the latency of running a DNN model or tensor program on a specific device is useful in various tasks, such as DNN graph- or tensor-level optimization and device selection. Considering the large space of DNN models and devices that impede direct profiling of all combinations, recent efforts focus on building a predictor to model the performance of DNN models on different devices. However, none of the existing attempts have achieved a cost model that can accurately predict the performance of various tensor programs while supporting both training and inference accelerators. We propose CDMPP, an efficient tensor program latency prediction framework for both cross-model and cross-device prediction. We design an informative but efficient representation of tensor programs, called compact ASTs, and a pre-order-based positional encoding method, to capture the internal structure of tensor programs. We develop a domain-adaption-inspired method to learn domain-invariant representations and devise a KMeans-based sampling algorithm, for the predictor to learn from different domains (i.e., different DNN operators and devices). Our extensive experiments on a diverse range of DNN models and devices demonstrate that CDMPP significantly outperforms state-of-the-art baselines with 14.03% and 10.85% prediction error for cross-model and cross-device prediction, respectively, and one order of magnitude higher training efficiency. The implementation and the expanded dataset are available at https://github.com/joapolarbear/cdmpp.

description: Neutron Stars are natural laboratories where fundamental properties of matter under extreme conditions can be explored. Modern nuclear physics input as well as many-body theories are valuable tools which may allow us to improve our understanding of the physics of those compact objects. In this work the occurrence of exotic structures in the outermost layers of neutron stars is investigated within the framework of a microscopic model. In this approach the nucleonic dynamics is described by a time-dependent mean field approach at around zero temperature. Starting from an initial crystalline lattice of nuclei at subnuclear densities the system evolves toward a manifold of self-organized structures with different shapes and similar energies. These structures are studied in terms of a phase diagram in density and the corresponding sensitivity to the isospin-dependent part of the equation of state and to the isotopic composition is investigated.

Year: 2015

description: This paper summarises current industrial practices and standards promoting Human Factors Engineering (HFE) at design stage and revise them with an action research approached based on the concrete case studies performed during a European project called TOSCA. The paper highlights how HFE can significantly impact the costs and risk associated with a plant lifecycle and the current gaps and issues encountered. The gaps identified are used to guide industrial practices and standards towards a more valuable inclusion of Human Factors knowledge in structured system design processes to support human performance and reduce the potential for human errors in operations and maintenance.
