description: We present a study of the environment of barred galaxies using a volume-limited sample of over 30,000 galaxies drawn from the Sloan Digital Sky Survey. We use four different statistics to quantify the environment: the projected two-point cross-correlation function, the background-subtracted number count of neighbor galaxies, the overdensity of the local environment, and the membership of our galaxies to galaxy groups to segregate central and satellite systems. For barred galaxies as a whole, we find a very weak difference in all the quantities compared to unbarred galaxies of the control sample. When we split our sample into early- and late-type galaxies, we see a weak but significant trend for early-type galaxies with a bar to be more strongly clustered on scales from a few 100 kpc to 1 Mpc when compared to unbarred early-type galaxies. This indicates that the presence of a bar in early-type galaxies depends on the location within their host dark matter halos. This is confirmed by the group catalog in the sense that for early-types, the fraction of central galaxies is smaller if they have a bar. For late-type galaxies, we find fewer neighbors within $\sim$50 kpc around the barred galaxies when compared to unbarred galaxies form the control sample, suggesting that tidal forces from close companions suppress the formation/growth of bars. Finally, we find no obvious correlation between overdensity and the bars in our sample, showing that galactic bars are not obviously linked to the large-scale structure of the universe.

description: We study the image reconstruction problem of a Compton camera which consists of semiconductor detectors. The image reconstruction is formulated as a statistical estimation problem. We employ a bin-mode estimation (BME) and extend an existing framework to a Compton camera with multiple scatterers and absorbers. Two estimation algorithms are proposed: an accelerated EM algorithm for the maximum likelihood estimation (MLE) and a modified EM algorithm for the maximum a posteriori (MAP) estimation. Numerical simulations demonstrate the potential of the proposed methods.

description: The star cluster surrounding the supermassive black hole in the center of Milky Way is probed using the data on the S2 star. The value of precession found at the physics-informed neural networks (PINN) analysis of the S2 data is used to consider the role of the scattering of S2 star on stars of the cluster, described by a random force given by the Holtsmark distribution. The critical value for the star density of the core cluster for which the observed precession value by PINN lies inside 70% confidence interval (between 15% and 85% quantiles) around the median of precession due to scattering, is obtained as n_crit \approx 8.3 10^6 pc^-3, that is at higher star densities the perturbation of the orbit of S2 would exceed the observed one.

description: Adjusting the photo color to associate with some design elements is an essential way for a graphic design to effectively deliver its message and make it aesthetically pleasing. However, existing tools and previous works face a dilemma between the ease of use and level of expressiveness. To this end, we introduce an interactive language-based approach for photo recoloring, which provides an intuitive system that can assist both experts and novices on graphic design. Given a graphic design containing a photo that needs to be recolored, our model can predict the source colors and the target regions, and then recolor the target regions with the source colors based on the given language-based instruction. The multi-granularity of the instruction allows diverse user intentions. The proposed novel task faces several unique challenges, including: 1) color accuracy for recoloring with exactly the same color from the target design element as specified by the user; 2) multi-granularity instructions for parsing instructions correctly to generate a specific result or multiple plausible ones; and 3) locality for recoloring in semantically meaningful local regions to preserve original image semantics. To address these challenges, we propose a model called LangRecol with two main components: the language-based source color prediction module and the semantic-palette-based photo recoloring module. We also introduce an approach for generating a synthetic graphic design dataset with instructions to enable model training. We evaluate our model via extensive experiments and user studies. We also discuss several practical applications, showing the effectiveness and practicality of our approach. Code and data for this paper are at: https://zhenwwang.github.io/langrecol.

description: Currently, many users of Social Network Sites are insufficiently aware of who can see their shared personal items. Nonetheless, most approaches focus on enhancing privacy in Social Networks through improved privacy settings, neglecting the fact that privacy awareness is a prerequisite for privacy control. Social Network users first need to know about privacy issues before being able to make adjustments. In this paper, we introduce Friend Inspector, a serious game that allows its users to playfully increase their privacy awareness on Facebook. Since its launch, Friend Inspector has attracted a significant number of visitors, emphasising the need for better tools to understand privacy settings on Social Networks.

description: Dynamic topic modeling is useful at discovering the development and change in latent topics over time. However, present methodology relies on algorithms that separate document and word representations. This prevents the creation of a meaningful embedding space where changes in word usage and documents can be directly analyzed in a temporal context. This paper proposes an expansion of the compass-aligned temporal Word2Vec methodology into dynamic topic modeling. Such a method allows for the direct comparison of word and document embeddings across time in dynamic topics. This enables the creation of visualizations that incorporate temporal word embeddings within the context of documents into topic visualizations. In experiments against the current state-of-the-art, our proposed method demonstrates overall competitive performance in topic relevancy and diversity across temporal datasets of varying size. Simultaneously, it provides insightful visualizations focused on temporal word embeddings while maintaining the insights provided by global topic evolution, advancing our understanding of how topics evolve over time.

description: This article investigates the impact of immigration on social cohesion and security in Germany, focusing on the consequences for peace, violence, and terrorism. As Germany has evolved into a multicultural society over the past few decades, the integration of immigrants has become a central challenge for both policymakers and citizens. By examining the historical context of immigration in Germany and the development of integration policies, this study seeks to understand how these factors influence social cohesion and the potential for conflict and terrorism. Drawing on empirical data and case studies, the analysis demonstrates the ways in which successful integration can foster social cohesion and contribute to a more peaceful society. However, it also reveals that integration challenges, such as social exclusion, cultural conflicts, and the rise of far-right extremism, can exacerbate tensions and lead to violence and terrorism. The article highlights the importance of addressing these challenges through inclusive policies and community engagement to promote harmony and security in Germany. In conclusion, the study underscores the need for a nuanced understanding of the relationship between immigration, social cohesion, and security in the context of peace, violence, and terrorism. It calls for a continued commitment to fostering an inclusive and harmonious society, where diverse communities can coexist and contribute to the greater stability and peace in Germany.

description: Halide scintillators play a crucial role in the detection of ionizing radiation since the discovery of scintillation in NaI:Tl in 1948. The discovery of NaI:Tl motivated the research and development (R&D) of halide scintillators resulting in the development of CsI:Tl, CsI:Na, CaF$_2$:Eu, etc. Later, the R&D shifted toward oxide materials due to their high mechanical and chemical stability, good scintillation properties, and relative ease of bulk single crystal growth. However, the development in crystal growth technology allowed for the growth of high-quality single crystals of hygroscopic and mechanically fragile materials including SrI$_2$ and LaBr$_3$. Scintillators based on these materials exhibit excellent performance and push the limits of inorganic scintillators. These results motivated intense research of a large variety of halide-based scintillators. Moreover, materials based on lead halide perovskites found application in the fields of photovoltaics, solid-state lighting, and lasers. The first studies show also the significant potential of lead halide perovskites as ultrafast scintillators in the form of NCs. The purpose of this review is to summarize the R&D in the field of halide scintillators during the last decade and to highlight perspectives for future development.

description: For the first time Lu$_2$S$_3$ (undoped and Pr-doped) single crystals were successfully grown from melt using micro-pulling-down (mPD) technique. Customization of halide mPD apparatus allowed us to grow rod-shaped (Ø2 mm and length around 20 mm) crystals of Lu$_2$S$_3$ with high melting temperature (~1750 $^\circ$C). X-ray powder diffraction revealed that the grown crystals exhibit the ε-Lu$_2$S$_3$ crystal structure ($α$-Al$_2$O$_3$ type, space group R-3c). Optical and scintillation properties of both the undoped and Pr$^{3+}$ doped Lu$_2$S$_3$ were investigated. Fast 5d-4f Pr$^{3+}$ luminescence was observed in both photoluminescence and radioluminescence spectra. The presented technology is an effective tool for the exploration of a large family of high-melting sulfides. Such materials show promise for application as scintillators, active laser media, and optoelectronic components.

The Mystery of the Cosmic Diffuse Ultraviolet Background Radiation

description: The diffuse cosmic background radiation in the GALEX far ultraviolet (FUV, 1300 Å - 1700 Å) is deduced to originate only partially in the dust-scattered radiation of FUV-emitting stars: the source of a substantial fraction of the FUV background radiation remains a mystery. The radiation is remarkably uniform at both far northern and far southern Galactic latitudes, and it increases toward lower Galactic latitudes at all Galactic longitudes. We examine speculation that it might be due to interaction of the dark matter with the nuclei of the interstellar medium but we are unable to point to a plausible mechanism for an effective interaction. We also explore the possibility that we are seeing radiation from bright FUV-emitting stars scattering from a "second population" of interstellar grains---grains that are small compared with FUV wavelengths. Such grains are known to exist (Draine 2011) and they scatter with very high albedo, with an isotropic scattering pattern. However, comparison with the observed distribution (deduced from their $100\ μ$m emission) of grains at high Galactic latitudes shows no correlation between the grains' location and the observed FUV emission. Our modeling of the FUV scattering by small grains also shows that there must be remarkably few such "smaller" grains at high Galactic latitudes, both North and South; this likely means simply that there is very little interstellar dust of any kind at the Galactic poles, in agreement with Perry & Johnston (1982). We also review our limited knowledge of the cosmic diffuse background at ultraviolet wavelengths shortward of Lyman $α$---it could be that our "second component" of the diffuse far-ultraviolet background persists shortward of the Lyman limit, and is the cause of the re-ionization of the Universe (Kollmeier et al. 2014).

description: The transforming growth factor-beta (TGF-beta) plays a pivotal role in the pathobiology of human gliomas: during carcinogenesis, it turns from a tumor suppressor to a tumor promoter. The traditional Smad pathway and the more recently discovered MAPK pathway are the most important pathways for TGF-beta related intracellular signal transduction mediating differential pathobiological effects. In this study, we investigated the effects of TGF-beta2 and the TGF-beta2 antisense phosphorothioate oligodeoxynucleotide (PTO) AS-11 on the functionality of both the Smad and MAPK pathways in high-grade gliomas. We aimed to correlate the imbalance between the pathways with differences in the behaviour of high-grade glioma cells. Gene and protein expression studies were used to detect levels of members of the Smad and MAPK pathways under regulation of TGF-beta2 and AS-11. Proliferation and migration assays were functional readouts for effects caused by these regulating tools. Gene arrays were used to detect yet unknown regulators of these functional effects. The Smad pathway was functional in the tested cell lines. Exogenous TGF-beta2 inhibited proliferation but enhanced migration. Smad 2 mRNA expression and activation were significantly reduced by incubation with AS-11. K-ras was reduced both in gene arrays and quPCR under treatment with AS-11, but there was no influence of K-ras down-regulation on the activity of ERK. Ubiquitination-related genes also were specifically down-regulated with AS-11. Our results indicate the involvement of K-ras in TGF-beta signaling in high-grade gliomas. ERK, which is a member of the MAPK pathway, was not influenced and seems to be activated through RAS independent cascades in glioma. These results suggest that combined antagonization of the TGF-beta and MAPK pathways might be a promising approach for glioma therapy. An imbalance between these two pathways might be responsible for TGF-beta switching to a tumor promoter protein in high-grade gliomas.

description: Perkembangan BMT di Indonesia, baik dilihat dari jumlah (unit) maupun aset menunjukkan pertumbuhan yang signifikan. BMT memiliki potensi yang besar untuk terus berkembang di tengah masyarakat perdesaan, bahkan pada masa yang akan dating diharapkan dapat menjadi referensi sumber permodalan utama dan penggerak aktivitas perekonomian masyarakat perdesaan. Dari studi kasus di Kabupaten Lampung Tengah dapat disimpulkan bahwa pembiayaan yang diperoleh petani dari BMT mampu meningkatkan pendapatan usahataninya. Akses pembiayaan dapat memperkuat sisi permodalan petani, sehingga jumlah dan kualitas input usahatani yang digunakan dapat diperbaiki. Perbaikan kualitas dan kuantitas input akan mendorong peningkatan produksi. Pada asumsi tingkat harga yang sama, peningkatan produksi dari petani yang mengakses pembiayaan dari BMT akan mengakibatkan mereka memperoleh pendapatan yang lebih tinggi jika dibandingkan dengan petani yang tidak mengakses pembiayaan. Berdasarkan kesimpulan tersebut, dapat disampaikan beberapa saran, yaitu: (1) Upaya pengentasan kemiskinan di Indonesia dapat di awali dari peningkatan pendapatan masyarakat perdesaan. Oleh karena itu, perlu dirancang strategi khusus terkait daya saing industri BMT sebagai lembaga pembiayaan mikro di perdesaan Indonesia. Program dan kegiatan dari rancangan strategi tersebut harus dilakukan secara terus menerus dan bertahap (sustainable development) sesuai tipologi perdesaan di Indonesia. (2) Untuk merealisasikan upaya pembangunan industri keuangan yang berkelanjutan, khususnya untuk lembaga keuangan mikro perdesaan, diperlukan kemitraan yang terintegrasi antara pemerintah dan swasta sebagai pelaku bisnis (investor). Program yang disusun hendaknya mampu menguntungkan swasta sehingga menjadi bisnis yang prospektif namun tetap memiliki eksternalitas positif jangka panjang khususnya bagi masyarakat petani di perdesaan, hingga tahap terbentuknya rantai nilai (shared value) perusahaan. (2) Perlu pengkondisian, komitmen, dan konsistensi terhadap kepentingan jangka panjang antara para pihak yang terkait, mulai dari pengelola BMT, Asosiasi BMT, organisasi kemasyarakatan, pusat pengembangan keilmuan (perguruan tinggi), pemerintah, serta pihak-pihak lainnya sebagai pemangku kepentingan (stakeholders).

description: Facilitated spin models were introduced some decades ago to mimic systems characterized by a glass transition. Recent developments have shown that a class of facilitated spin models is also able to reproduce characteristic signatures of the structural relaxation properties of glass-forming liquids. While the equilibrium phase diagram of these models can be calculated analytically, the dynamics are usually investigated numerically. Here we propose a new network-based approach, called approximate master equation (AME), to the dynamics of the Fredrickson-Andersen model. The approach correctly predicts the critical temperature at which the glass transition occurs. We also find excellent agreement between the theory and the numerical simulations for the transient regime, except in close proximity of the liquid-glass transition. Finally, we analytically characterize the critical clusters of the model and show that the departures between our AME approach and the Monte Carlo can be related to the large interface between frozen and unfrozen spins at temperatures close to the glass transition.

description: Expression quantitative trait loci (eQTL) mapping constitutes a challenging problem due to, among other reasons, the high-dimensional multivariate nature of gene-expression traits. Next to the expression heterogeneity produced by confounding factors and other sources of unwanted variation, indirect effects spread throughout genes as a result of genetic, molecular and environmental perturbations. From a multivariate perspective one would like to adjust for the effect of all of these factors to end up with a network of direct associations connecting the path from genotype to phenotype. In this paper we approach this challenge with mixed graphical Markov models, higher-order conditional independences and q-order correlation graphs. These models show that additive genetic effects propagate through the network as function of gene-gene correlations. Our estimation of the eQTL network underlying a well-studied yeast data set leads to a sparse structure with more direct genetic and regulatory associations that enable a straightforward comparison of the genetic control of gene expression across chromosomes. Interestingly, it also reveals that eQTLs explain most of the expression variability of network hub genes.

We check that this transport approach allows to reproduce the chiral anomaly equation of relativistic quantum field theory at finite temperature. We also check that it allows to describe the anomalous gauge polarization tensor that appears in the Hard Thermal (and/or Dense) effective field theory. We also construct an energy density associated to the gauge collective modes of the chiral relativistic plasma, valid in the case of small couplings or weak fields, which can be the basis for the study of their dynamical evolution.

description: The variety of today's multicore architectures motivates researchers to explore parallel scientific applications on different platforms. Load imbalance is one performance issue that can prejudice parallel applications from exploiting the computational power of these platforms. Ondes3D is a scientific application for seismic wave simulation used to assess the geological impact of earthquakes. Its parallelism relies on applying a regular domain decomposition in the geological domain provided and distributing each sub-domain to MPI ranks. Previous works investigate the significant spatial and temporal imbalance in Ondes3D and suggest new parallelization and load balancing techniques to minimize them. However, none explored its execution on different architectures. Our paper evaluates the performance of Ondes3D for two earthquake scenarios on eight different multicore architectures, including Intel, AMD, and ARM processors. We measure the load distribution per MPI rank, evaluate the temporal load imbalance, and compare the execution of the application's kernels. Our results show that the temporal load imbalance in Ondes3D depends on the architecture chosen, with some platforms minimizing such imbalance more effectively.

description: Multimodal recommendation exploits the rich multimodal information associated with users or items to enhance the representation learning for better performance. In these methods, end-to-end feature extractors (e.g., shallow/deep neural networks) are often adopted to tailor the generic multimodal features that are extracted from raw data by pre-trained models for recommendation. However, compact extractors, such as shallow neural networks, may find it challenging to extract effective information from complex and high-dimensional generic modality features. Conversely, DNN-based extractors may encounter the data sparsity problem in recommendation. To address this problem, we propose a novel model-agnostic approach called Semantic-guided Feature Distillation (SGFD), which employs a teacher-student framework to extract feature for multimodal recommendation. The teacher model first extracts rich modality features from the generic modality feature by considering both the semantic information of items and the complementary information of multiple modalities. SGFD then utilizes response-based and feature-based distillation loss to effectively transfer the knowledge encoded in the teacher model to the student model. To evaluate the effectiveness of our SGFD, we integrate SGFD into three backbone multimodal recommendation models. Extensive experiments on three public real-world datasets demonstrate that SGFD-enhanced models can achieve substantial improvement over their counterparts.

We present the analytical expressions for the convex roof coherence measures, $C_f(ρ)$, of one-qubit states with $C_f(φ):=f(\abs{c_0}^2,\abs{c_1}^2)$ (where $\ketφ=c_0\ket{0}+c_1\ket{1}$) being convex with respect to the $l_1$ norm of coherence of $φ$ (i.e., $C_{l_1}(φ)$), such coherence measures including the coherence of formation, the geometric measure of coherence, the coherence concurrence, and the coherence rank. We further present the operational interpretations of these measures. Finally, we present the usefulness of the convex roof coherence measures $C_f(φ)$ being non-convex with respect to $C_{l_1}(φ)$ by giving the necessary and sufficient conditions for the transformations $pφ_1\oplus(1-p)φ_2\to qϕ_1\oplus(1-q)ϕ_2$ via incoherent operations, where $φ_i$, $ϕ_j$ $(i, j=1, 2)$ are one-qubit pure states and $0\leq p, q\leq 1$.

description: Given any $\varepsilon>0$, we construct an orthonormal system of $n_k$ uniformly bounded polynomials of degree at most $k$ on the unit sphere in $\mathbb R^{m+1}$ where $n_k$ is bigger than $1-\varepsilon$ times the dimension of the space of polynomials of degree at most $k$. Similarly we construct an orthonormal system of sections of powers $L^k$ of a positive holomorphic line bundle on a compact Kähler manifold with cardinality bigger than $1-\varepsilon$ times the dimension of the space of global holomorphic sections to $L^k$.

The C IV forest as a probe of baryon acoustic oscillations

description: In light of recent successes in measuring baryon acoustic oscillations in quasar absorption using the Lyman $α$ (Ly$α$) transition, I explore the possibility of using the 1548Å transition of triply ionized carbon (C IV) as a tracer. While the Ly-alpha forest is a more sensitive tracer of intergalactic gas, it is limited by the fact that it can only be measured in the optical window at redshifts $z > 2$. Quasars are challenging to identify and observe at these high-redshifts, but the C IV forest can be probed down to redshifts $z \approx 1.3$, taking full advantage of the peak in the redshift distribution of quasars that can be targeted with high efficiency. I explore the strength of the C IV absorption signal and show that the absorbing population on the red side of the Ly-alpha emission line is dominated by C IV (and so will dominate over the potential BAO signal of other metals). As a consequence, I argue that forthcoming surveys may have a sufficient increase in quasar number density to offset the lower sensitivity of the C IV forest and provide competitive precision using both the C IV autocorrelation and the C IV-quasar cross-correlation at $< z > \approx 1.6$.

description: The study assesses the awareness of PSU Bayambang Campus students regarding e-learning technologies. A Quantitative Research Approach was used, gathering data through a demographic questionnaire and ICT Resources assessment. The survey measured students' familiarity and knowledge of existing e-learning technologies. Around 52.50% of respondents were familiar with e learning concepts, but their exposure and utilization levels need consideration. Technology, Support, and Users were identified as key factors influencing student awareness. Implementation can be improved through policies and resource provision. The researchers recommend integrating e learning policies, providing ICT Resources and Infrastructure, and offering training for students and teachers. This research serves as a guide for policy design, enhancing the University's learning process and facilitating better learning and interaction.

Scaling behavior of charged hadron $p_{T}$ distributions in $pp$ and $p\bar{p}$ collisions

description: We report on a scaling behaviour in the transverse momentum ($p_{T}$) distributions for charged hadrons produced in proton-proton ($pp$) collisions with different center of mass energies ($\sqrt{s}$ = 0.9, 2.76 and 7 TeV) at the Compact Muon Solenoid (CMS) detector. This scaling behaviour appears when the $p_{T}$ is replaced by $p_{T}/K$, where $K$ is a parameter and depends on $\sqrt{s}$. A similar scaling behaviour is observed in the $p_{T}$ distributions of charged hadrons produced in proton-antiproton ($p\bar{p}$) collisions with $\sqrt{s}$ = 0.63, 1.8 and 1.96 TeV at the Collider Detector at Fermilab (CDF). The particle production mechanism behind the scaling behaviour in the $pp$ or $p\bar{p}$ collisions could be explained by the model of percolation of strings.

description: Measurement-device-independent quantum key distribution (MDI-QKD), leaving the detection procedure to the third partner and thus being immune to all detector side-channel attacks, is very promising for the construction of high-security quantum information networks. We propose a scheme to implement MDI-QKD, but with continuous variables instead of discrete ones, i.e., with the source of Gaussian-modulated coherent states, based on the principle of continuous-variable entanglement swapping. This protocol not only can be implemented with current telecom components but also has high key rates compared to its discrete counterpart; thus it will be highly compatible with quantum networks.

description: Just noticeable difference (JND) refers to the maximum visual change that human eyes cannot perceive, and it has a wide range of applications in multimedia systems. However, most existing JND approaches only focus on a single modality, and rarely consider the complementary effects of multimodal information. In this article, we investigate the JND modeling from an end-to-end homologous multimodal perspective, namely hmJND-Net. Specifically, we explore three important visually sensitive modalities, including saliency, depth, and segmentation. To better utilize homologous multimodal information, we establish an effective fusion method via summation enhancement and subtractive offset, and align homologous multimodal features based on a self-attention driven encoder-decoder paradigm. Extensive experimental results on eight different benchmark datasets validate the superiority of our hmJND-Net over eight representative methods.

description: Context and motivation: Design Thinking techniques have been widely used in the elicitation of software requirements, since such methods obtain satisfying results when applied to understand the necessities of both stakeholders and end-users. However, there is a lack of evidence on their effectiveness when applied to populations considered vulnerable. Question/problem: What are the implications of using Design Thinking techniques to elicit requirements in a community of former inmates - and what would be the benefits of and challenges in this deployment? Principal ideas/results: in this paper, we report our experience on using Design Thinking for Requirements Elicitation of a mobile application, customized for a vulnerable population: the former inmates of the Brazilian Prison System and their families. Research approach and methodology: Techniques such as Brainstorming, Stakeholder Mapping, Personas Creation, Rapid Ethnography, and Interviews were used to obtain relevant data. Furthermore, during the development process, several prototypes were created.Contribution: The use of these techniques generated important contributions for the development of an uncommon application that aims to help the reintegration process of former inmates into society. The results obtained validate the initial hypothesis that such techniques, even when applied to a sensitive context such as this one, assist in the development of a product that meets the needs of the end-users by creating a higher quality product. Limitations of results:The main limitation of the research was the lack of access to low literacy end-users and/or former inmates without previous experience using mobile devices.
