description: A line-depth ratio (LDR) of two spectral lines with different excitation potentials is expected to be correlated with the effective temperature ($T_\mathrm{eff}$). It is possible to determine $T_\mathrm{eff}$ of a star with a precision of tens of Kelvin if dozens or hundreds of tight LDR-$T_\mathrm{eff}$ relations can be used. Most of the previous studies on the LDR method were limited to optical wavelengths, but Taniguchi and collaborators reported 81 LDR relations in the $YJ$ band, 0.97-1.32 $μ\mathrm{m}$, in 2018. However, with their sample of only 10 giants, it was impossible to account for the effects of surface gravity and metallicity on the LDRs well. Here we investigate the gravity effect based on $YJ$-band spectra of 63 stars including dwarfs, giants, and supergiants observed with the WINERED spectrograph. We found that some LDR-$T_\mathrm{eff}$ relations show clear offsets between the sequence of dwarfs and those of giants/supergiants. The difference between the ionization potentials of the elements considered in each line pair and the corresponding difference in the depths can, at least partly, explain the dependency of the LDR on the surface gravity. In order to expand the stellar parameter ranges that the LDR method can cover with high precision, we obtained new sets of LDR-$T_\mathrm{eff}$ relations for solar-metal G0-K4 dwarfs and F7-K5 supergiants, respectively. The typical precision that can be achieved with our relations is 10-30 K for both dwarfs and supergiants.

description: The problem of the stabilization of moduli is discussed within the context of compactified strongly coupled heterotic string theory. It is shown that all geometric, vector bundle and five-brane moduli are completely fixed, within a phenomenologically acceptable range, by non-perturbative physics. This result requires, in addition to the full space of moduli, non-vanishing Neveu-Schwarz flux, gaugino condensation with threshold corrections and the explicit form of the Pfaffians in string instanton superpotentials. The stable vacuum presented here has a negative cosmological constant. The possibility of ``lifting'' this to a metastable vacuum with positive cosmological constant is briefly discussed.

We investigate the $2+D+d$ dimensional cosmological model in some detail.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We have calculated the ground-state energy of the doubly magic nuclei 4He, 16O and 40Ca within the framework of the Goldstone expansion starting from various modern nucleon-nucleon potentials. The short-range repulsion of these potentials has been renormalized by constructing a low-momentum potential V-low-k. We have studied the connection between the cutoff momemtum Lambda and the size of the harmonic oscillator space employed in the calculations. We have found a fast convergence of the results with a limited number of oscillator quanta.

description: Water-borne cryptosporidiosis, a neglected parasitic disease, presents a serious threat to human health due to the ubiquitous distribution of Cryptosporidium species affecting humans and animals, and due to the resistance of the oocysts to harsh environmental conditions, various disinfectants, and some common therapeutic agents. Water is a great reservoir for contamination and a potential medium of transmission of the pathogen. The present study was aimed to isolate and identify Cryptosporidium oocysts in water samples in Bangladesh. Water samples from small ponds, waste water bodies and drains were collected from different areas of the Mymensingh and Kushtia districts of Bangladesh. To detect Cryptosporidium, the samples were assessed by microscopy, using the conventional Ziehl-Neelsen staining method, and by PCR. By microscopy, Cryptosporidium oocysts were detected in 5 (25%) of 20 samples examined collected from the Mymensingh district, which were further confirmed by PCR. Importantly, Cryptosporidium was detected by PCR in drain water but was not detected by conventional microscopy. In the Kushtia district, 2 (20%) of the 10 samples examined by microscopy were positive. Cryptosporidium was not detected in waste water by conventional microscopy and PCR. However, the results confirm the presence of Cryptosporidium in different types of sources of water in both Mymensingh and Kushtia districts, demonstrating the existence of Cryptosporidium in the study areas. Further studies are need to explore the present status of prevalence of Cryptosporidium in humans and animals in order to better understand the transmission dynamics of the parasite and thereafter take necessary measures to control and/or prevent the disease.

description: As the world population continues to grow at an alarming rate, the environmental strains that we have stressed on the earth have placed humans in a huge crisis. Following the global warming problem, the sustainability of ecology and social and economic states is more important than ever. This paper conducts a sustainability assessment of food services and products at the University of British Columbia based on a commodity chain analysis on canned tuna and salmon. Our hypothesis was that UBC could play a role in bridging knowledge and action for reducing food products’ carbon footprint. Our research focused on the harvesting methods, processing, packaging, transportation, consumer demands, and waste disposal generated at any point along the chain of producing and consuming fish products. Our research results supported our hypothesis by showing that we could achieve the sustainability of fish by changing the views and diet habit of people through educating the general public.

description: The most common way to assess handedness is based on the preferred hand for writing, leading to a binary (left or right) trait. Handedness can also be assessed as a continuous trait with laterality indexes, but these are not time- and cost-effective, and are not routinely collected. Rarely, different handedness measures are collected for the same individuals. Here, we assessed the relationship of preferred hand for writing with four laterality indexes, reported in previous literature, derived from measures of dexterity (pegboard task, marking squares and sorting matches) and strength (grip strength), available in a range of N = 6664–8069 children from the ALSPAC cohort. Although all indexes identified a higher proportion of individuals performing better with their right hand, they showed low correlation with each other (0.08–0.3). Left handers were less consistent compared to right handers in performing better with their dominant hand, but that varied across indexes, i.e. 13% of left handers performed better with their right hand on marking squares compared to 48% for sorting matches and grip strength. Analysis of sex effects on the laterality indexes showed that males and females tend to be, on all measures, more left- and right-lateralized, respectively. Males were also over-represented among the individuals performing equally with both hands suggesting they had a higher tendency to be weakly lateralized. This study shows that different handedness measures tap into different dimensions of laterality and cannot be used interchangeably. The trends observed across indexes for males and females suggest that sex effects should be taken into account in handedness and laterality studies.

description: Abstract: This study examines the impact of music ministry on spiritual growth among youth in congregational settings, addressing a crucial gap in understanding the role of music in young people's faith development. While music's significance in worship is widely recognized, its specific effects on youth spiritual formation remain underexplored. This research investigates how participation in music ministry influences spiritual growth, identifies key aspects of music ministry that foster spiritual development, and explores the correlation between music ministry integration and overall youth engagement in religious activities. The study employed a mixed-methods approach, involving 250 youth participants (ages 13-21) from 10 diverse Christian congregations over a 12-month period. Data collection included pre- and post-study surveys, semi-structured interviews, observational data from music ministry sessions and worship services, and focus groups. Quantitative data were analyzed statistically, while qualitative data underwent thematic analysis using a grounded theory approach. Results indicate a strong positive correlation between music ministry participation and increased spiritual engagement (r = 0.72, p < 0.001). Key findings include enhanced understanding of faith concepts through music (reported by 82% of participants), stronger emotional connections to spirituality (89%), improved sense of community (r = 0.68, p < 0.001), and increased leadership development within the congregation. Contemporary worship styles were preferred, but traditional hymns were also appreciated when their theological content was explained. The study concludes that music ministry significantly impacts youth spiritual growth through multiple pathways, including emotional engagement, community building, and leadership opportunities. These findings suggest that intentionally structured music ministry programs can be powerful tools for nurturing spiritual development in young congregants. Future research should explore long-term impacts and applicability across diverse religious contexts.

description: Bilinear pooling achieves great success in fine-grained visual recognition (FGVC). Recent methods have shown that the matrix power normalization can stabilize the second-order information in bilinear features, but some problems, e.g., redundant information and over-fitting, remain to be resolved. In this paper, we propose an efficient Multi-Objective Matrix Normalization (MOMN) method that can simultaneously normalize a bilinear representation in terms of square-root, low-rank, and sparsity. These three regularizers can not only stabilize the second-order information, but also compact the bilinear features and promote model generalization. In MOMN, a core challenge is how to jointly optimize three non-smooth regularizers of different convex properties. To this end, MOMN first formulates them into an augmented Lagrange formula with approximated regularizer constraints. Then, auxiliary variables are introduced to relax different constraints, which allow each regularizer to be solved alternately. Finally, several updating strategies based on gradient descent are designed to obtain consistent convergence and efficient implementation. Consequently, MOMN is implemented with only matrix multiplication, which is well-compatible with GPU acceleration, and the normalized bilinear features are stabilized and discriminative. Experiments on five public benchmarks for FGVC demonstrate that the proposed MOMN is superior to existing normalization-based methods in terms of both accuracy and efficiency. The code is available: https://github.com/mboboGO/MOMN.

description: In the past few years, small scale anisotropy has become a primary focus in the search for source of Ultra-High Energy Cosmic Rays (UHECRs). The Akeno Giant Air Shower Array (AGASA) has reported the presence of clusters of event arrival directions in their highest energy data set. The High Resolution Fly's Eye (HiRes) has accumulated an exposure in one of its monocular eyes at energies above 10^(19.5) eV comparable to that of AGASA. However, monocular events observed with an air fluorescence detector are characterized by highly asymmetric angular resolution. A method is developed for measuring autocorrelation with asymmetric angular resolution. It is concluded that HiRes-I observations are consistent with no autocorrelation and that the sensitivity to clustering of the HiRes-I detector is comparable to that of the reported AGASA data set. Furthermore, we state with a 90% confidence level that no more than 13% of the observed HiRes-I events above 10^(19.5) eV could be sharing common arrival directions. However, because a measure of autocorrelation makes no assumption of the underlying astrophysical mechanism that results in clustering phenomena, we cannot claim that the HiRes monocular analysis and the AGASA analysis are inconsistent beyond a specified confidence level.

description: We investigate the highly incoherent regime of hole-doped 2d Mott-Hubbard insulators at moderately small doping and temperatures T>=0.1J, where J is the exchange coupling. Within an extended dynamical mean-field theory of the t-J model and a generalized non-crossing approximation we calculate the single-particle spectral function, the dynamical susceptibility, and thermodynamic and transport quantities. Short-ranged antiferromagnetic fluctuations lead to strongly incoherent single-particle dynamics, large entropy and large electrical resistivity. At low doping a pseudogap is found to open up both in the single-particle and the spin excitation spectra leading to a decrease in entropy and resistivity. The Hall coefficient changes sign to positive values upon lowering the doping level and increases inversely proportional to doping.

description: We report measurements on single-electron pumps, consisting of two metallic islands formed by three tunnel junctions in series. We focus on the linear-response conductance as a function of gate voltage and temperature of three samples with varying system parameters. In all cases, strong quantum fluctuation phenomena are observed by a log(k_B T/(2 E_co)) reduction of the maximal conductance, where E_co measures the coupling strength between the islands. The samples display a rich phenomenology, culminating in a non-monotonic behavior of the maximal conductance as a function of temperature.

We show that in models where the right handed neutrino masses, $M_R$ arise from the breaking of local B-L symmetry by a Higgs field with B-L=2, some of the leptogenesis phases can lead to enhancement of the lepton dipole moments compared to the prediction of models where $M_R$ is either directly put in by hand or is a consequence of a higher dimensional operator.

description: As 5G network deployments advance, the opportunities to embed intelligence on the network to support network slicing, fault management, resource management, etc are still available. Intelligence in 5G networks through machine learning and artificial intelligence techniques can be bolstered for adoption by the availability of realistic, open, free, and available datasets. However, this is not always the case. Alongside the lack of openly available and free datasets for experimentation, operators are faced with the need to protect the privacy of their users and businesses. Thus, they cannot easily grant access to 5G networking datasets. However, this gap can be bridged with the small-scale deployment of 5G networks as private test networks. Technically, the availability of open-source and configurable software for 5G experimentation makes it possible to realize experiments on data collection and dataset building. In this work, we propose a framework and detailed methodology that can be used to build application-level datasets in 5G networks. An application-level dataset aims to track the characteristics of an application from the Radio Access Network to the Core Network and display features that can best describe this specific application. In this work, the primary focus is on the user plane traffic on the 5G network. We implement the framework on a physical testbed deployed using srsRAN for gNB radio propagation on an Ettus research X310 Software Defined Radio. Our core network is based on Open5Gs. We write custom packet filtering Quality of Service rules to map QoS flows in the Core network to Data Radio bearers in the Radio Access Network to isolate Spotify traffic on a logical end-to-end QoS pipe. We use this logical end-to-end traffic isolation to capture packets and frames on Wireshark. The packet captures are parsed on a custom script wrapping t-shark filter to expose 5G user plane network features that can be filled with input to create an end-to-end 5G networking dataset.

description: We use a symmetry-motivated approach to analysing X-ray pair distribution functions to study the mechanism of negative thermal expansion in two ReO$_3$-like compounds; ScF$_3$ and CaZrF$_6$. Both average and local structure suggest that it is the flexibility of M-F-M linkages (M = Ca, Zr, Sc) due to dynamic rigid and semi-rigid 'scissoring' modes that facilitates the observed NTE behaviour. The amplitudes of these dynamic distortions are greater for CaZrF$_6$ than for ScF$_3$, which corresponds well with the larger magnitude of the thermal expansion reported in the literature for the former. We show that this flexbility is enhanced in CaZrF$_6$ due to the rock-salt ordering mixing the characters of two of these scissoring modes. Additionally, we show that in ScF$_3$ anharmonic coupling between the modes responsible for the structural flexibility and the rigid unit modes contributes to the unusually high NTE behaviour in this material.

T_{f} increases with frequency and the dielectric response shows universal scaling in a Cole-Cole plot, suggesting that a charge glass state is realized both in the cuprates and in the nickelates.

description: We present the initial results from an in-depth re-examination of the MACHO project Large Magellanic Cloud database to identify and characterize stellar variability near the intersection of the instability strip and the main sequence. This dataset's long time-series and uniform photometry is an unprecedented resource for describing the frequency and regions of incidence of various radial and non-radial modes of excitation. The raw MACHO photometry has been investigated to identify factors responsible for most of the residual photometric variance and increase the sensitivity to small amplitudes. We present details of the search method used, the Delta Scuti variables detected thus far and discuss the implications for the completed survey.

description: Deciding whether to forgo a good choice in favour of exploring a potentially more rewarding alternative is one of the most challenging arbitrations both in human reasoning and in artificial intelligence. Humans show substantial variability in their exploration, and theoretical but only limited empirical, work has suggested that excessive exploration is a critical mechanism underlying the psychiatric dimension of impulsivity. In this registered report, we put these theories to test using large online samples, dimensional analyses, and computational modelling. Capitalising on recent advances in disentangling distinct human exploration strategies, we will assess whether impulsivity is associated with specific forms of exploration, in particular value-free random exploration. Our results will not only examine these popular theories empirically, but can also provide crucial novel insights into the mechanisms underlying one of the most relevant psychiatric dimensions.

description: We study the coherent dynamics of a qubit excited by an amplitude-modulated electromagnetic field under the Rabi resonance when the frequency of the low-frequency modulation field matches the Rabi frequency in the high-frequency field. Due to destructive interference of multiple photon processes at the ultrastrong coupling between the qubit and the low-frequency driving field, Rabi oscillations result exclusively from the Bloch-Siegert effect. It is directly observed in the time-resolved coherent dynamics as the Bloch-Siegert oscillation. In this case, triplets in Fourier spectra of the coherent response are transformed into doublets with the splitting between the lines equal to twice the Bloch-Siegert shift. These unusual properties are demonstrated in conditions of experiments with a nitrogen vacancy center in diamond.

On subspaces of non-commutative L_p-spaces

description: We study some structural aspects of the subspaces of the non-commutative (Haagerup) L_p-spaces associated with a general (non necessarily semi-finite) von Neumann algebra A. If a subspace X of L_p(A) contains uniformly the spaces \ell_p^n, n>= 1, it contains an almost isometric, almost 1-complemented copy of \ell_p. If X contains uniformly the finite dimensional Schatten classes S_p^n, it contains their \ell_p-direct sum too. We obtain a version of the classical Kadec-Pel czynski dichotomy theorem for L_p-spaces, p>= 2. We also give operator space versions of these results. The proofs are based on previous structural results on the ultrapowers of L_p(A), together with a careful analysis of the elements of an ultrapower [L_p(A)]_U which are disjoint from the subspace L_p(A). These techniques permit to recover a recent result of N. Randrianantoanina concerning a Subsequence Splitting Lemma for the general non-commutative L_p spaces. Various notions of p-equiintegrability are studied (one of which is equivalent to Randrianantoanina's one) and some results obtained by Haagerup, Rosenthal and Sukochev for L_p -spaces based on finite von Neumann algebras concerning subspaces of L_p(A) containing \ell_p are extended to the general case.

description: Let $\mathcal{H}$ be the class of bounded measurable symmetric functions on $[0,1]^2$. For a function $h \in \mathcal{H}$ and a graph $G$ with vertex set $\{v_1,\ldots,v_n\}$ and edge set $E(G)$, define \[ t_G(h) \; = \; \int \cdots \int \prod_{\{v_i,v_j\} \in E(G)} h(x_i,x_j) \: dx_1 \cdots dx_n \: . \] Answering a question raised by Conlon and Lee, we prove that in order for $t_G(|h|)^{1/|E(G)|}$ to be a norm on $\mathcal{H}$, the graph $G$ must be edge-transitive.

description: Methods for calculating an electron density of a periodic crystal constructed using non-orthogonal localised orbitals are discussed. We demonstrate that an existing method based on the matrix expansion of the inverse of the overlap matrix into a power series can only be used when the orbitals are highly localised (e.g. ionic systems). In other cases including covalent crystals or those with an intermediate type of chemical bonding this method may be either numerically inefficient or fail altogether. Instead, we suggest an exact and numerically efficient method which can be used for orbitals of practically arbitrary localisation. Theory is illustrated by numerical calculations on a model system.

description: We substantiate by calculations that the recently discovered superconductivity below 4 K in 3% boron-doped diamond is caused by electron-phonon coupling of the same type as in MgB$_2$, albeit in 3 dimensions. Holes at the top of the zone-centered, degenerate $σ$-bonding valence band couple strongly to the optical bond-stretching modes. The increase from 2 to 3 dimensions reduces the mode-softening crucial for $T_{c}$ reaching 40 K in MgB$_{2}.$ Even if diamond had the same \emph{bare} coupling constant as MgB$_{2},$ which could be achieved with 10% doping, $T_{c}$ would only be 25 K. Superconductivity above 1 K in Si (Ge) requires hole-doping beyond 5% (10%).

description: Biological filaments driven by molecular motors tend to experience tangential propulsive forces also known as active follower forces. When such a filament encounters an obstacle, it deforms, which reorients its follower forces and alters its entire motion. If the filament pushes a cargo, the friction on the cargo can be enough to deform the filament, thus affecting the transport properties of the cargo. Motivated by cytoskeletal filament motility assays, we study the dynamic buckling instabilities of a two-dimensional slender elastic filament driven through a dissipative medium by tangential propulsive forces in the presence of obstacles or cargo. We observe two distinct instabilities. When the filament’s head is pinned or experiences significant translational but little rotational drag from its cargo, it buckles into a steadily rotating coiled state. When it is clamped or experiences both significant translational and rotational drag from its cargo, it buckles into a periodically beating, overall translating state. Using minimal analytically tractable models, linear stability theory and fully nonlinear computations, we study the onset of each buckling instability, characterize each buckled state, and map out the phase diagram of the system. Finally, we use particle-based Brownian dynamics simulations to show our main results are robust to moderate noise and steric repulsion. Overall, our results provide a unified framework to understand the dynamics of tangentially propelled filaments and filament-cargo assemblies.

description: Community based action research was conducted to assess the sustainability of the current UBC Food Services (UBCFS) products. Data was collected mainly through online research, literature reviews, and contacting relevant UBCFSP partners, current UBCFS suppliers and potential new suppliers via emails, phone calls or personal interviews. Our focus was evaluating the sustainability of one of the main staple ingredients, flour. Sustainability of conventional and organic flour was assessed through ecological footprints, production and processing practices, packaging and waste disposal, and possible health effects; the potential of switching from conventional flour to organic and local flour was also examined. Even though, UBCFS expressed interest in purchasing more sustainable organic flour, the main obstacle preventing this change is cost. Organic flours costs up to three times more than conventionally produced flour and thus, increasing input prices would surely lead to increased food prices at UBC. Our group recommends future AGSC 450 students to extend our research by exploring more local and organic suppliers for other staple food items of interest to UBCFS. It will also be important to raise students’ awareness on the advantages of local and organic food products through education and advertisement. Survey can be conducted to statistically analyze students’ willingness to accept higher prices for higher quality products. As a way to advertise UBCFS efforts to supply more sustainable food products, we feel that it will be beneficial to put a recognizable logo on food products that are made from organic and local ingredients.

description: Combining the results of [14] and [10], the trend to equilibrium in large time is studied for a large particle system associated to a Vlasov-Fokker-Planck equation. Under some conditions (that allow non-convex confining potentials) the convergence rate is proven to be independent from the number of particles. From this are derived uniform in time propagation of chaos estimates and an exponentially fast convergence for the nonlinear equation itself.

description: Large volume Liquid Argon Time Projection Chambers (LAr-TPC) are used and proposed for neutrino physics and rare event search. Most of these detectors make use of the scintillation light of liquid argon for trigger purposes. Two different approaches can be adopted to provide these detectors with an effective trigger system, relying upon analog or digital processing of signal coming from photodetectors, like photomultiplier tubes or silicon photomultipliers. Each method presents advantages and drawbacks, so the implementation of a hybrid solution can benefit from both approaches. To this purpose, an innovative electronic board prototype has been designed and proposed for the use in large volume LAr-TPC detectors.
title: The perceived dilemma between debt reduction and a fair society: saving for a rainy day without increasing poverty?

description: Reducing debts and deficits in economic stable times has become the overarching policy goal after the financial and sovereign debt crisis. In an era of low growth, fiscal consolidation is seen as the central key to achieving the latter, however, often resulting in a trade-off between equality and efficiency. In this article, we study whether it is possible to achieve the seemingly impossible: pursuing successful fiscal consolidation without sharp increases in poverty. For this, we apply a fuzzy-set qualitative comparative analysis (fsQCA) among the countries of the European Economic Area (EEA) plus Switzerland between 1994 and 2019, excluding “the rainy day” (2008-2013) of the financial and the sovereign debt crisis. The absence of sluggish economic growth is identified as a necessary condition for reaching the outcome. Moreover, we find multiple sufficient paths, including such that are not export-driven but rely on domestic strategies (via high employment and a strong left) to achieve fair fiscal consolidation. However, to what extent such a strategy is still possible in the future remains an open question.

description: We show that the "defective" terms in the expression that Dondera [Phys. Rev. D 98, 096008 (2018)] obtained for the momentum of the retarded field of an accelerating point charge are mathematically well justified. The repair should not be sought in assigning an accelerating "bare" charge ad hoc compensating attributes. We advance a conjecture, supported by published work, concerning the Hadamard finite part of the divergent integral for the retarded-field momentum in question.
