description: In this work we design an end-to-end deep learning architecture for predicting, on Chest X-rays images (CXR), a multi-regional score conveying the degree of lung compromise in COVID-19 patients. Such semi-quantitative scoring system, namely Brixia~score, is applied in serial monitoring of such patients, showing significant prognostic value, in one of the hospitals that experienced one of the highest pandemic peaks in Italy. To solve such a challenging visual task, we adopt a weakly supervised learning strategy structured to handle different tasks (segmentation, spatial alignment, and score estimation) trained with a "from-the-part-to-the-whole" procedure involving different datasets. In particular, we exploit a clinical dataset of almost 5,000 CXR annotated images collected in the same hospital. Our BS-Net demonstrates self-attentive behavior and a high degree of accuracy in all processing stages. Through inter-rater agreement tests and a gold standard comparison, we show that our solution outperforms single human annotators in rating accuracy and consistency, thus supporting the possibility of using this tool in contexts of computer-assisted monitoring. Highly resolved (super-pixel level) explainability maps are also generated, with an original technique, to visually help the understanding of the network activity on the lung areas. We also consider other scores proposed in literature and provide a comparison with a recently proposed non-specific approach. We eventually test the performance robustness of our model on an assorted public COVID-19 dataset, for which we also provide Brixia~score annotations, observing good direct generalization and fine-tuning capabilities that highlight the portability of BS-Net in other clinical settings. The CXR dataset along with the source code and the trained model are publicly released for research purposes.

description: Recent work has demonstrated the existence of universal Hamiltonians - simple spin lattice models that can simulate any other quantum many body system to any desired level of accuracy. Until now proofs of universality have relied on explicit constructions, tailored to each specific family of universal Hamiltonians. In this work we go beyond this approach, and completely classify the simulation ability of quantum Hamiltonians by their complexity classes. We do this by deriving necessary and sufficient complexity theoretic conditions characterising universal quantum Hamiltonians. Although the result concerns the theory of analogue Hamiltonian simulation - a promising application of near-term quantum technology - the proof relies on abstract complexity theoretic concepts and the theory of quantum computation. As well as providing simplified proofs of previous Hamiltonian universality results, and offering a route to new universal constructions, the results in this paper give insight into the origins of universality. For example, finally explaining the previously noted coincidences between families of universal Hamiltonian and classes of Hamiltonians appearing in complexity theory.

description: The thesis analyzes the causal relationship between the cotton spot, and the tendency and impact of prices of futures markets in Xinjiang by using ADF test, co-integration analysis, Granger causality test and other econometric methods in order to discuss the interacted relationship between futures market prices of cotton and spot market prices since the futures of cotton in Xinjiang go public. The results of empirical analysis show that the spot market prices of cotton and the futures market prices in Xinjiang fluctuate prominently in the short run and tend to counterpoise in the long run; the futures market of cotton plays the role of leading the spot market prices of cotton in Xinjiang, while the spot market prices of cotton in Xinjiang impacts little on the futures market prices. The corresponding countermeasures are put forward. The government should continuously perfect the construction of the futures market of cotton in Xinjiang, so as to exert the function of price discovery and the function of hedging, and promote the development of cotton industry in Xinjiang.

description: Gravitational-wave memory effects are identified by their distinctive effects on families of freely falling observers: after a burst of waves pass by their locations, memory effects can cause lasting relative displacements of the observers. These effects are closely related to the infrared properties of gravity and other massless field theories, including their asymptotic symmetries and conserved quantities. In this paper, we investigate the connection between memory effects, symmetries, and conserved quantities in Brans-Dicke theory. We compute the field equations in Bondi coordinates, and we define a set of boundary conditions that represent asymptotically flat solutions in this context. Next, we derive the asymptotic symmetry group of these spacetimes, and we find that it is the same as the Bondi-Metzner-Sachs group in general relativity. Because there is an additional polarization of gravitational waves in Brans-Dicke theory, we compute the memory effects associated with this extra polarization (the so-called "breathing" mode). This breathing mode produces a uniform expansion (or contraction) of a ring of freely falling observers. After these breathing gravitational waves pass by the observers' locations, there are two additional memory effects that depend on their initial displacements and relative velocities. Neither of these additional memory effects seems to be related to asymptotic symmetries or conserved quantities; rather, they are determined by the properties of the nonradiative region before and after the bursts of the scalar field and the gravitational waves. We discuss the properties of these regions necessary to support nontrivial breathing-mode-type memory effects.

description: A Bluetooth finder is a small battery-powered device that can be attached to important items such as bags, keychains, or bikes. The finder maintains a Bluetooth connection with the user's phone, and the user is notified immediately on connection loss. We provide the first comprehensive security and privacy analysis of current commercial Bluetooth finders. Our analysis reveals several significant security vulnerabilities in those products concerning mobile applications and the corresponding backend services in the cloud. We also show that all analyzed cloud-based products leak more private data than required for their respective cloud services. Overall, there is a big market for Bluetooth finders, but none of the existing products is privacy-friendly. We close this gap by designing and implementing PrivateFind, which ensures locations of the user are never leaked to third parties. It is designed to run on similar hardware as existing finders, allowing vendors to update their systems using PrivateFind.

description: The new rural cooperative medical system has achieved periodical achievements since its establishment. Nevertheless, there are many factors hampering the development of the new system, such as the high cost, the difficulties in fund procurement, the lack of management, the narrow coverage of benefit, the ineffective constraint to the designated medical institutions, the high fund balance rate, and the poor medical facilities and services in rural areas. Countermeasures are put forward to solve these problems, including improving the system design, expanding the coverage of the system, expanding the fund sources, reducing the financing costs, strengthening the fund supervision, enhancing the supervision of designated medical institutions, and improving the capacity of health services in rural areas.

Both attractive and repulsive forces, determined by the choice of relative input phase, are found. Using realistic parameters for a silicon-on-insulator material system, we estimate that the forces are large enough to cause observable displacements. Our results illustrate the potential for a broader class of optically-tunable microphotonic devices and microstructured artificial materials.

description: By operating the radio frequency single electron transistor (rf-SET) as a mixer we present measurements in which the RC roll-off of the tunnel junctions is observed at high frequencies. Our technique makes use of the non-linear rf-SET transconductance to mix high frequency gate signals and produce difference-frequency components that fall within the bandwidth of the rf-SET. At gate frequencies >15GHz the induced charge on the rf-SET island is altered on time-scales faster than the inverse tunnel rate, preventing mixer operation. We suggest the possibility of utilizing this technique to sense high frequency signals beyond the usual rf-SET bandwidth.

Kainate receptors containing GluR5 subunits contribute to synaptic transmission and long-term potentiation in the hippocampal dentate gyrus
Creators: name: Tse, Maric Tsz Lung.
Publisher: name: University of British Columbia
Year: 2009

description: It has recently been shown that presynaptic kainate receptors can play a role in synaptic plasticity in the CA3 region of the hippocampus (Bortolotto et al., 1999); however, a role for these receptors in synaptic transmission and synaptic plasticity in other regions of the brain has been difficult to establish. In the present experiments we show that kainate receptors can contribute significantly to synaptic transmission in the dentate gyrus (DG) of the hippocampus, and that furthermore, they appear to play a role in synaptic plasticity in this region. Kainate receptors in the DG appear to be located post-synaptically at excitatory synapses where they can influence synaptic plasticity by alleviating the M g 2+ blockade of NMD A receptors. These results demonstrate that kainate receptors in the DG play a vital post-synaptic role at excitatory synapses, and may contribute to learning and memory processes in this region.

The Near-Infrared Spectrum of the Nuclear Star Cluster: Looking Below the Tip of the Iceberg and Comparisons with Extragalactic Nuclei

description: Long-slit near-infrared (NIR) spectra of the Galactic nuclear star cluster (NSC) are discussed. The spectra sample the major axis of the NSC out to its half light radius. The equivalent widths of NaI2.21um and CaI2.26um outside of the center of the NSC, where light from nuclear bulge stars contributes a large fraction to the total flux, are consistent with solar chemical mixtures. In contrast, the equivalent widths of NaI2.21um and CaI2.26um near the center of the NSC are larger than expected from models with solar chemical mixtures, even after light from the brightest evolved stars is removed. That NaI2.21um and CaI2.26um are deeper than predicted for solar chemical mixtures over a range of evolutionary states is consistent with previous studies that find that the majority of stars near the center of the NSC formed from material that had non-solar chemical mixtures. A spectrum of nebular emission and the youngest stars near the GC is also extracted. The equivalent widths of emission features in the extracted NIR spectrum are similar to those in the nuclear spectrum of NGC 253, and it is argued that this agreement is best achieved if the current episode of star formation near the center of the NSC has been in progress for at least a few Myr.

The main problems existing in the process of coordinating urban-rural development of Chongqing City are discussed under the foregoing framework. We find that input and flow direction of capital deviating from “agriculture, rural areas and farmers” is the direct cause of insufficient rural educational input, insufficient agricultural input, and irrational rural input, while the fundamental reason lies in the irrational financial policy. Based on this, the measure of innovating upon financial policy and financial system are put forward.

description: This study provides a brain-based account of how object concepts at an intermediate (basic) level of specificity arerepresented, offering an enriched view of what it means for a concept to be a basic-level concept, a research topicpioneered by Rosch and others (Rosch et al., 1976). Applying machine learning techniques to fMRI data, it waspossible to determine the semantic content encoded in the neural representations of object concepts at basic andsubordinate levels of abstraction. The representation of basic-level concepts (e.g. bird) was spatially broad,encompassing sensorimotor brain areas that encode concrete object properties, and also language and heteromodalintegrative areas that encode abstract semantic content. The representation of subordinate-level concepts(robin) was less widely distributed, concentrated in perceptual areas that underlie concrete content. Furthermore,basic-level concepts were representative of their subordinates in that they were neurally similar to their typicalbut not atypical subordinates (bird was neurally similar to robin but not woodpecker). The findings provide a brainbasedaccount of the advantages that basic-level concepts enjoy in everyday life over subordinate-level concepts:the basic level is a broad topographical representation that encompasses both concrete and abstract semanticcontent, reflecting the multifaceted yet intuitive meaning of basic-level concepts.

Determinants of child protection from exposure to environmental tobacco smoke in the home
Creators: name: Timmerman, Tracey Lynne
Publisher: name: University of British Columbia
Year: 2009

description: Exposure to environmental tobacco smoke (ETS) has a considerable negative impact on the health of children, and has been causally associated with chronic bronchitis and pneumonia, chronic ear infection due to the build up of fluid in the middle ear and the exacerbation and induction of asthma. The most important source of exposure to ETS for children is the home, and significant reductions in exposure to ETS can result from restricting smoking in the home. Several controlled trials of interventions designed to encourage smokers living with children to adopt smoking restrictions in their households or to stop smoking altogether have been published, but have shown limited success. In the future, interventions involving the entire household unit may be more effective, and an essential foundation on which to build such interventions will include knowledge of the characteristics of households with varying levels of household smoking restriction. The objectives of this study were twofold: 1) to examine the relationship between household socio-demographic variables and the level of smoking restriction in households that include both adult smokers and children under the age of 18 years, and 2) to examine this relationship utilizing ordinal and nominal regression methods to contribute to the understanding of the nature of the progression from a low level of smoking restriction to a high level of smoking restriction in the home. These objectives were met by performing a secondary analysis of data previously collected as part of the ETS in the Home National Survey. The results of this analysis indicated that the odds of having a high level of smoking restriction in the home were significantly lower for families residing in apartments and/or condominiums compared to single detached homes, families residing in Quebec compared to Ontario, and households with older children. The odds for having a high level of household smoking restriction were significantly higher for households residing in British Columbia compared to Ontario. These results were consistent in direction and magnitude with results of similar studies reported previously in the literature.

description: Upcoming wide-field surveys are well-suited to studying the growth of galaxy clusters by tracing galaxy and gas accretion along cosmic filaments. We use hydrodynamic simulations of volumes surrounding 324 clusters from \textsc{The ThreeHundred} project to develop a framework for identifying and characterising these filamentary structures, and associating galaxies with them. We define 3-dimensional reference filament networks reaching $5R_{200}$ based on the underlying gas distribution and quantify their recovery using mock galaxy samples mimicking observations such as those of the WEAVE Wide-Field Cluster Survey. Since massive galaxies trace filaments, they are best recovered by mass-weighting galaxies or imposing a bright limit (e.g. $>L^*$) on their selection. We measure the transverse gas density profile of filaments, derive a characteristic filament radius of $\simeq0.7$--$1~h^{-1}\rm{Mpc}$, and use this to assign galaxies to filaments. For different filament extraction methods we find that at $R>R_{200}$, $\sim15$--$20%$ of galaxies with $M_*>3 \times 10^9 M_{\odot}$ are in filaments, increasing to $\sim60%$ for galaxies more massive than the Milky-Way. The fraction of galaxies in filaments is independent of cluster mass and dynamical state, and is a function of cluster-centric distance, increasing from $\sim13$% at $5R_{200}$ to $\sim21$% at $1.5R_{200}$. As a bridge to the design of observational studies, we measure the purity and completeness of different filament galaxy selection strategies. Encouragingly, the overall 3-dimensional filament networks and $\sim67$% of the galaxies associated with them are recovered from 2-dimensional galaxy positions.

Subjects: classificationCode: 520504
subject: Psychology of religion

description: This study examines the relationship between death awareness and psychological resilience in adults aged 50 and above, focusing on the roles of religious activity, recent death experiences, and educational background. A total of 52 participants completed surveys measuring death awareness (TBS-5) and resilience (RS-10). Results indicated that religiously active individuals reported significantly lower death anxiety and higher resilience compared to non-religious participants. Additionally, individuals who had experienced the death of a loved one in the past 12 months showed a tendency toward greater openness in discussing death. No significant effects were found for educational background. While the small sample size limits the generalizability of the findings, the study highlights the importance of religious and experiential factors in shaping attitudes toward mortality and offers practical implications for end-of-life care and counseling. The results also suggest that fostering open dialogue about death and enhancing spiritual support may increase psychological resilience among older adults.

description: For magnetic-dipolar modes in a ferrite, components of the magnetic flux density in a helical coordinate system are dependent on both an orientation of a gyration vector and a sign of a pitch. It gives four types of helical harmonics for magnetostatic-potential wave functions in a ferrite disk. Because of the reflection symmetry breaking, coupling between certain types of helical harmonics takes place in the reflection points. The reflection feature leads to exhibition of two types of resonances: the "right" and "left" resonances. These resonances become coupled for a ferrite disk placed in a homogeneous tangential RF magnetic field. One also observes such resonance coupling for a ferrite disk with a symmetrically oriented linear surface electrode, when this ferrite particle is placed in a homogeneous tangential RF electric field. In a cylindrical coordinate system handedness of magnetic-dipolar modes in a ferrite disk is described by spinor wave functions.

First, we establish that a polynomial matrix $P(x)$ with chordal sparsity is positive semidefinite for all $x\in \mathbb{R}^n$ if and only if there exists a sum-of-squares (SOS) polynomial $σ(x)$ such that $σP$ is a sum of sparse SOS matrices. Second, we show that setting $σ(x)=(x_1^2 + \cdots + x_n^2)^ν$ for some integer $ν$ suffices if $P$ is homogeneous and positive definite globally. Third, we prove that if $P$ is positive definite on a compact semialgebraic set $\mathcal{K}=\{x:g_1(x)\geq 0,\ldots,g_m(x)\geq 0\}$ satisfying the Archimedean condition, then $P(x) = S_0(x) + g_1(x)S_1(x) + \cdots + g_m(x)S_m(x)$ for matrices $S_i(x)$ that are sums of sparse SOS matrices. Finally, if $\mathcal{K}$ is not compact or does not satisfy the Archimedean condition, we obtain a similar decomposition for $(x_1^2 + \ldots + x_n^2)^νP(x)$ with some integer $ν\geq 0$ when $P$ and $g_1,\ldots,g_m$ are homogeneous of even degree. Using these results, we find sparse SOS representation theorems for polynomials that are quadratic and correlatively sparse in a subset of variables, and we construct new convergent hierarchies of sparsity-exploiting SOS reformulations for convex optimization problems with large and sparse polynomial matrix inequalities. Numerical examples demonstrate that these hierarchies can have a significantly lower computational complexity than traditional ones.

description: Целью статьи является анализ философских и теологических аспектов иконоборчества с учётом его различных форм и секулярных аналогов. Исследование основывается на анализе семиотических особенностей иконоборческой установки в качестве отрицания, запрета или целенаправленного разрушения определённых визуальных образов. Принципы, критерии и практики иконоборчества рассматриваются в статье в аспектах семантики и прагматики. Подчёркивается, что каждое общество нуждается в средствах, обеспечивающих разделение визуальных образов на приемлемые (истинные) и неприемлемые (ложные). Хотя считается, что соответствующие принципы, критерии и практики возникли в условиях монотеизма, отмечается, что у иконоборчества есть аналог в ранних формах религии.

description: We present high resolution VLT UVES observations of the active K dwarf GJ 117. 6^Li enhancement has been shown for energetic solar events, one chromospherically active binary, and several dwarf halo stars. Our analysis reveals the detection of 6^Li on this source with 6^Li/7^Li = 0.030+/-0.010. We found no significant contribution from other lines, including Ti I, in the Li profile of GJ 117 and a template star of similar spectral type and metallicity. We discuss the possibility for 6^Li production by spallation and find it to be consistent with the activity levels of the object.

description: Several old problems in the new countryside construction at present are analyzed. For instance the land transfer mechanism is not flexible, land problems have restricted the development of agricultural industrialization; farmers still have serious problems in income increase and lack the rational investment and consumption awareness; farmers receive low level of education and their cultural qualities are general poor; for a long time, legalization and democratization process of rural grass-roots organizations has been lagged behind. Causations for problems in the new countryside construction are various, such as lacking the subject consciousness, a long-term mechanism, industrial support and capital input. Finally, several new ideas about the construction of socialist new countryside are put forward, including speeding up the development of modern agriculture and doing everything possible to increase the income of farmers; paying attention to the development of civilized villages and towns and doing everything possible to enrich the knowledge of farmers; accelerating the establishment of long-term mechanism and gathering the ideas of farmers to the maximum extent; fully integrating project funds and constructing the socialist new countryside.

description: Deep neural networks have shown great success in many diverse fields. The training of these networks can take significant amounts of time, compute and energy. As datasets get larger and models become more complex, the exploration of model architectures becomes prohibitive. In this paper we examine the compute, energy and time costs of training a UNet based deep neural network for the problem of predicting short term weather forecasts (called precipitation Nowcasting). By leveraging a combination of data distributed and mixed-precision training, we explore the design space for this problem. We also show that larger models with better performance come at a potentially incremental cost if appropriate optimizations are used. We show that it is possible to achieve a significant improvement in training time by leveraging mixed-precision training without sacrificing model performance. Additionally, we find that a 1549% increase in the number of trainable parameters for a network comes at a relatively smaller 63.22% increase in energy usage for a UNet with 4 encoding layers.

description: В статье рассмотрена картина «Явление Христа народу»
А. Иванова в качестве ценного объекта изучения визуальной теологии методом герменевтики образов. Поражает огромность задачи, которая стояла перед художником. Центральное событие мировой истории – приход в мир Спасителя – столь дерзновенно вместил в свою картину А. Иванов. Фактически А. Иванов даёт в своей картине обзор судеб человеческого рода, подобный тому, который мы видим в «Божественной комедии» Данте. В отличие от последней, в картине ограниченное количество персонажей, и поэтому каждый из них должен был стать символом какого-то важнейшего характера и явления в жизни человечества. В истории европейской живописи нет подобных картин, к ним могут приближаться по замыслу только многосюжетные росписи храмов, сделанные художниками – «титанами Возрождения».
Neural representations of the concepts in simple sentences: Concept activation prediction and context effects

description: Although it has been possible to identify individual concepts from a concept's brain activation pattern, therehave been significant obstacles to identifying a proposition from its fMRI signature. Here we demonstrate theability to decode individual prototype sentences from readers’ brain activation patterns, by using theory-drivenregions of interest and semantic properties. It is possible to predict the fMRI brain activation patterns evoked bypropositions and words which are entirely new to the model with reliably above-chance rank accuracy. The twocore components implemented in the model that reflect the theory were the choice of intermediate semanticfeatures and the brain regions associated with the neurosemantic dimensions. This approach also predicts theneural representation of object nouns across participants, studies, and sentence contexts. Moreover, we find thatthe neural representation of an agent-verb-object proto-sentence is more accurately characterized by the neuralsignatures of its components as they occur in a similar context than by the neural signatures of thesecomponents as they occur in isolation.

description: Cavity-based quantum node is a competitive platform for distributed quantum networks. Here, we characterize a high-finesse Fabry-Perot optical resonator for coupling single or few atomic quantum registers. Our cavity consists of two mirrors with different reflectivities: One has minimal optical loss, and the other high transmission loss where more than 90% of the intracavity photons would be emitted. Cavity finesse, birefringent effects, and mechanical resonances are measured using the lasers at 780, 782, and 795 nm. In order to obtain cavity geometric parameters, we drive the adjacent longitudinal or transverse modes with two lasers simultaneously, and measure those frequencies using a precision wavelength meter (WLM). A major novelty of this method is that the parameters' uncertainties are solely determined by the resolution of the WLM, eliminating all of the temporal environment fluctuations. Our scheme makes it possible to quantify the atom-cavity coupling constant up to four significant figures, the most precise and accurate estimation so far, which would become a key ingredient for benchmarking a cavity-based quantum node. Furthermore, the distortion of polarized photonic qubits would be minimized owing to the small birefringent splitting, below 4.9% of the cavity linewidth. Our system should operate in the intermediate atom-cavity coupling regime that would allow us to implement various quantum network protocols.
