description: Three new naphthoquinone-based meroterpenoids (1–3), including spironaphthomeroterpenoid (1), a novel naphthoquinone-based meroterpenoid with a rare [5, 6] spiro-ring skeleton, and naphthablins D and E (2–3), along with three known analogues (4–6) were isolated from Streptomyces sp. HBERC-16614. The structures of these compounds, including their absolute configurations, were established by extensive spectroscopic analysis and electronic circular dichroism (ECD) spectrum. The antibacterial activities of compounds (1–6) were evaluated against Staphylococcus aureus, Streptococcus suis, and Escherichia coli. Among them, compound 1 demonstrated potent antibacterial activity against S. aureus, with a minimum inhibitory concentration (MIC) value of 3.13 µg/mL.

description: Summary: In the process of modernizing medicine, convergent NBIC technologies are grafting themselves onto the medical sector. By intertwining with it, they do not fail to assist the doctor in his various functions by offering facilities for the diagnostic and therapeutic aspects. This is how we can see the health specialist being truly assisted, the patient for his part greatly relieved by the presence of new clinical possibilities, and general health normally better. From these elements, we can affirm that medicine is fortunate to have on its side these technologies that improve it qualitatively. This is a question of a transhumanism that bears a humanist stamp. But the danger is not far off because stopping at such a remark is reductionist. These same technologies by promoting transhumanism benefiting man indeed, risk leading us towards a surpassing of what is precious in us, namely our humanity. Posthumanism thus appears as the veiled element of transhumanism, presented as a lamb through convergent NBIC technologies. Ultimately, we must embrace and adopt an extreme prudence that pushes us to be sufficiently attentive to all NBIC technological productions to hope to avoid the cataclysm of humanity. In this sense, ethics committees must play a decisive role.

description: Polygonum tinctorium Ait., a well-documented medicinal herb in traditional Chinese medicine, is commonly utilised in the form of its leaves, known as ‘Liao da qing ye’ in Chinese Pharmacopoeia. Investigations into the phytochemical constituents of P. tinctorium have resulted in the identification of three distinct five-membered heterocyclic frameworks. This includes the isolation of two novel heterocyclic compounds (1 and 2) alongside four previously characterised pyrrolidine alkaloids. Structural elucidation of these compounds was achieved through HRESIMS and comprehensive spectroscopic analysis. Notably, compound 1 features a furan-based core structure, while compound 2 possesses a pyrrole-based framework. The isolated compounds were subsequently evaluated for their inhibitory potential against α-glycosidase and acetylcholinesterase enzymes.

description: Magnetic monopoles have a long history of theoretical predictions and experimental searches, carrying direct implications for fundamental concepts such as electric charge quantization. We analyze in detail for the first time magnetic monopole production from collisions of cosmic rays bombarding the atmosphere. This source of monopoles is independent of cosmology, has been active throughout Earth's history, and supplies an irreducible monopole flux for all terrestrial experiments. Using results for robust atmospheric fixed target experiment flux of monopoles, we systematically establish direct comparisons of previous ambient monopole searches with monopole searches at particle colliders and set leading limits on magnetic monopole production in the $\sim 5-100$ TeV mass-range.

description: This is the paper for the first place winning solution of the Drone vs. Bird Challenge, organized by AVSS 2021. As the usage of drones increases with lowered costs and improved drone technology, drone detection emerges as a vital object detection task. However, detecting distant drones under unfavorable conditions, namely weak contrast, long-range, low visibility, requires effective algorithms. Our method approaches the drone detection problem by fine-tuning a YOLOv5 model with real and synthetically generated data using a Kalman-based object tracker to boost detection confidence. Our results indicate that augmenting the real data with an optimal subset of synthetic data can increase the performance. Moreover, temporal information gathered by object tracking methods can increase performance further.

description: Large-scale astronomical surveys have the potential to capture data on large numbers of strongly gravitationally lensed supernovae (LSNe). To facilitate timely analysis and spectroscopic follow-up before the supernova fades, an LSN needs to be identified soon after it begins. To quickly identify LSNe in optical survey datasets, we designed ZipperNet, a multi-branch deep neural network that combines convolutional layers (traditionally used for images) with long short-term memory (LSTM) layers (traditionally used for time series). We tested ZipperNet on the task of classifying objects from four categories -- no lens, galaxy-galaxy lens, lensed type Ia supernova, lensed core-collapse supernova -- within high-fidelity simulations of three cosmic survey data sets -- the Dark Energy Survey (DES), Rubin Observatory's Legacy Survey of Space and Time (LSST), and a Dark Energy Spectroscopic Instrument (DESI) imaging survey. Among our results, we find that for the LSST-like dataset, ZipperNet classifies LSNe with a receiver operating characteristic area under the curve of 0.97, predicts the spectroscopic type of the lensed supernovae with 79\% accuracy, and demonstrates similarly high performance for LSNe 1-2 epochs after first detection. We anticipate that a model like ZipperNet, which simultaneously incorporates spatial and temporal information, can play a significant role in the rapid identification of lensed transient systems in cosmic survey experiments.

description: Collision with building windows is one of the main causes of direct humanrelated bird deaths in North America, particularly during migration seasons. Vancouver has the highest densities of wintering birds of any Canadian city, so occupants on the University of British Columbia campus were interested in finding out whether or not bird collisions are a significant problem. As a result, for a period of eight months, four Environmental Sciences students, partnering up with The UBC SEEDS program, UBC Sustainability and Engineering, UBC Building Operations and Environment Canada, compiled and analyzed birdcollision data on the UBC Vancouver campus. The project mainly focuses on the problem of birdbuilding collisions and the severity of the situation. Ten buildings were chosen for their have high percentage of glass cover and are suspected to be the most problematic on campus. The number of bird collisions at each selected building were then recorded and examined for patterns. Since this study is one of the first birdwindow collision studies on UBC, the results will help to inform future UBC birdfriendly building guidelines and future studies.

description: It is well known that the topological entanglement entropy ($S_{topo}$) of a topologically ordered ground state in 2 spatial dimensions can be captured efficiently by measuring the tripartite quantum information ($I^{3}$) of a specific annular arrangement of three subsystems. However, the nature of the general N-partite information ($I^{N}$) and quantum correlation of a topologically ordered ground state remains unknown. In this work, we study such $I^N$ measure and its nontrivial dependence on the arrangement of $N$ subsystems. For the collection of subsystems (CSS) forming a closed annular structure, the $I^{N}$ measure ($N\geq 3$) is a topological invariant equal to the product of $S_{topo}$ and the Euler characteristic of the CSS embedded on a planar manifold, $|I^{N}|=χS_{topo}$. Importantly, we establish that $I^{N}$ is robust against several deformations of the annular CSS, such as the addition of holes within individual subsystems and handles between nearest-neighbour subsystems. For a general CSS with multiple holes ($n_{h}>1$), we find that the sum of the distinct, multipartite informations measured on the annular CSS around those holes is given by the product of $S_{topo}$, $χ$ and $n_{h}$, $\sum^{n_{h}}_{μ_{i}=1}|I^{N_{μ_{i}}}_{μ_{i}}| = n_{h}χS_{topo}$. The $N^{th}$ order irreducible quantum correlations for an annular CSS of $N$ subsystems is also found to be bounded from above by $|I^{N}|$, which shows the presence of correlations among subsystems arranged in the form of closed loops of all sizes. Our results offer important insight into the nature of the many-particle entanglement and correlations within a topologically ordered state of matter.

Sustainable landscapes at UBC : an environmental and social sustainability assessment of UBC Vancouver’s stormwater terraces using the SITES v2 Rating System and the UBC community’s input

description: UBC has an expansive landscape and would like to know the degree to which the existing landscapes meet the landscape sustainability criteria developed by The Sustainable Sites Initiative (SITES). The landscape assessed in this project is the stormwater terraces at UBC’s Vancouver Point Grey Campus, which replaced a parking lot in 2013. Located near the heart of campus, it is also important to capture the thoughts and opinions of the UBC community on the stormwater terraces to reflect its social sustainability. The stormwater terraces are assessed for 1) environmental sustainability based on relevant Water and Soil & Vegetation criteria found in the SITES v2 Rating System from the Sustainable Sites Initiative program and for 2) social sustainability via a questionnaire completed by fifty randomly selected UBC community members in the vicinity of the terraces. The stormwater terraces do not meet most of the relevant Water criteria largely due to the lack of a site maintenance plan and the additional potable water usage (for maintenance and continuous flow) but they do meet the relevant Soil & Vegetation criteria. Should SITES certification be pursued for future UBC landscapes, it is recommended that projects follow SITES guidelines from start to finish and that maintenance plans be developed and followed (to document activities and improve communication between various working departments). The UBC community generally views the presence of the stormwater terraces as a positive aspect of campus, despite its use of extra potable water. Feasible recommendations to improve the social perceptions of the feature as suggested by the UBC community include reducing the amount of visible cement, making the anti-skateboarding ridges less obvious/obtrusive to sitting/lying in the area, and changing the shape of water funneling flutes in the terraces. Additional landscape assessments in the future would help to further the understanding of how UBC landscapes measure against the benchmark landscape sustainability criteria of SITES.

description: ABSTRACT

This paper explores a leadership style that is all embracing, free of rancor a misgiving. The growth of every establishment is sacrosanct to the minds ~: leaders. One major challenge that leaders in Nigeria and some parts of Africa faces in its developmental strive is "leadership". This has led to failures and disregard for subordinates. These challenges are however not farfetched, as the style adopted by leaders either mar or make their establishments. The developmental growth of any sector is attributed to good leadership (style). Being a good leader is like conducting a symphony: You don't necessarily know how to play each instrument but you do know how to make the instruments work together to produce music. Accordingly, three main leadership styles were identified in the study. Success depends upon a number of variables, including the style adopted by the leaders which invariably leads to building better qualities of the following and aspects of the situation. The paper then submits that the democratic style leadership is most effective as it bring about effective leadership qualities in establishment.

description: We propose a method to substantially improve the signal-to-noise ratio of lattice correlation functions for bosonic operators or other operator combinations with disconnected contributions. The technique is applicable for correlations between operators on two planes (zero momentum correlators) when the dimension of the plane is larger than the separation between the two planes which are correlated. In this case, the correlation arises primarily from points whose in-plane coordinates are close, but noise arises from all pairs of points. By breaking each plane into bins and computing bin-bin correlations, it is possible to capture these short-distance correlators exactly while replacing (small) correlators at large spatial extent with a fit, with smaller uncertainty than the data. The cost is only marginally larger than averaging each plane before correlating, but the improvement in signal-to-noise can be substantial. We test the method on correlators of the gradient-flowed topological charge density and squared field strength, finding noise reductions by a factor of $\sim$ 3$-$7 compared to the conventional approach on the same ensemble of configurations.

description: We explore the interplay between randomness and magnetic frustration in the series of $S = 1/2$ Heisenberg square-lattice compounds Sr$_2$CuTe$_{1-x}$W$_x$O$_6$. Substituting W for Te alters the magnetic interactions dramatically, from strongly nearest-neighbor to next-nearest-neighbor antiferromagnetic coupling. We perform neutron scattering measurements to probe the magnetic ground state and excitations over a range of $x$. We propose a bond-disorder model that reproduces ground states with only short-ranged spin correlations in the mixed compounds. The calculated neutron diffraction patterns and powder spectra agree well with the measured data and allow detailed predictions for future measurements. We conclude that quenched randomness plays the major role in defining the physics of Sr$_2$CuTe$_{1-x}$W$_x$O$_6$ with frustration being less significant.

description: Utilizing quantum coherence monotone, we reexamine the thermal nature of the Unruh effect of an accelerating detector. We consider an UDW detector coupling to a n-dimensional conformal field in Minkowski spacetime, whose response spectrum generally exhibits an intermediate statistics of (1+1) anyon field. We find that the thermal nature of the Unruh effect guaranteed by KMS condition is characterized by a vanishing asymptotic quantum coherence. We show that the time-evolution of coherence monotone can distinguish the different thermalizing ways of the detector, which depends on the scaling dimension of the conformal primary field. In particular, for the conformal background with certain scaling dimension, we demonstrate that at fixed proper time a revival of coherence can occur even for growing Unruh decoherence. Finally, we show that coherence monotone has distinct dynamics under the Unruh decoherence and a thermal bath for a static observer.

description: High entropy carbides ceramics with randomly-distributed multiple principal cations have shown high temperature stability, low thermal conductivity, and possible radiation tolerance. While chemical disorder has been shown to suppress thermal conductivity in these materials, little investigation has been made on the effects of additional, extrinsically-generated structural defects on thermal transport. Here, (Zr$_{0.25}$Ta$_{0.25}$Nb$_{0.25}$Ti$_{0.25}$)C is exposed to Zr ions to generate a micron-scale, structural-defect-bearing layer. The reduction in lattice thermal transport is measured using laser thermoreflectance. Conductivity changes from different implantation temperatures suggest dislocation loops contribute little to phonon scattering while nanoscale defects serve as effective scatterers, offering a pathway for thermal engineering.

description: We review the possible violation of the Equivalence Principle at finite temperature T in the framework of curvature based Extended Theories of Gravity. Specifically, we first show how it is possible to derive Equivalence Principle violation from Quantum Field Theory at non-vanishing T. Subsequently, we exhibit how this result can be precisely recovered by following an alternative path that envisages the employment of generalized Einstein equations with a temperature-dependent energy-momentum tensor. Finally, we adopt the latter formalism in the context of some Extended Gravity models to quantify the amount of Equivalence Principle violation. Specifically, Brans-Dicke Theory, Standard Model Extension and Conformal Gravity are considered in details.
On effects of surface bipolar magnetic regions on the convection zone dynamo

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We investigate the effect of the surface bipolar magnetic regions (BMR) on the large-scale dynamo distributed in the bulk of the convection zone. The study employs the nonlinear 3D mean-field dynamo model. We model the emergence of the BMR on the surface through the nonaxisymmetric magnetic buoyancy effect, which acts on the large-scale toroidal magnetic field in the upper half of the convection zone. The nonaxisymmetric magnetic field which results from this mechanism is shallow. On the surface, the effect of the BMR on the magnetic field generation is dominant. {However, because of the shallow BMR distribution, its effect on the global dynamo is less compared to the convective zone dynamo.} We find that the mean-field $α$ effect, which acts on the nonaxisymmetric magnetic field of the BMRs, provides the greater contribution to the dynamo process than the BMR's tilt does. Even so, the fluctuations of the BMR's tilt lead to the parity braking in the global dynamo. At the surface the nonaxisymmetric magnetic field, which are generated because of the BMR's activity, shows a tendency for the bihelical spectrum with the positive sign for the low $\ell$ modes during the maximum of the magnetic activity cycle.

description: In this paper, we establish connections between reflected entropies of multipartite mixed states in CFT$_{2}$ and hyperbolic string vertices of closed string field theory (CSFT). We show that the reflected surfaces, which are bulk duals of the reflected entropies, share the same Riemann surfaces with the hyperbolic string vertices. This observation enables us to build quantitative relations between the reflected entropies and hyperbolic string vertices. We illustrate the connections with several examples. Consequently, we propose that spacetime structure could be directly generated from the hyperbolic string vertices. The advantage of the hyperbolic string vertices approach is that we have a dynamical equation, the Batalin-Vilkoviski master equation, to control the generating process.

description: The only available electroweak measurement of the $^{208}\mathrm{Pb}$ neutron skin, $ΔR_{\rm{np}}$, performed by the PREX-II Collaboration through polarized electron-lead scattering, shows a mild tension with respect to both the theoretical nuclear-model predictions and a host of measurements. However, the dependence on the weak mixing angle should be incorporated in the calculation, since its low-energy value is experimentally poorly known. We first repeat the PREX-II analysis confirming their measurement by fixing the weak mixing angle to its standard model value. Then, we show the explicit dependence of the PREX-II measurement on the weak mixing angle, obtaining that it is fully degenerate with the neutron skin. To break this degeneracy, we exploit the weak mixing angle measurement from atomic parity violation on lead, obtaining a slightly thinner neutron skin but with about doubled uncertainties, possibly easing the PREX tension. Relying on the theoretical prediction, $ΔR_{\rm{np}}^{\mathrm{th}}\approx 0.13-0.19\ \mathrm{fm}$, and using it as a prior in the fit, we find a weak mixing angle value about $1.2σ$ smaller than the standard model prediction. Thus, we suggest a possible solution of the PREX-II tension by showing that, considering its underlying dependence on the weak mixing angle, the PREX-II neutron skin determination could be in agreement with the other available measurements and predictions if the weak mixing angle at the proper energy scale is smaller than the standard model prediction.

From Compliance Costs to Competitive Advantage: Quantifying the Effects of EU Non-Tariff Measures under EVFTA on Vietnam's Textile and Apparel Exports
Creators: name: Do Phu Hai*
Publisher: name: Zenodo
Year: 2025
Subjects: Non-Tariff Measures, EVFTA, Vietnam Textile and Apparel Exports, Sustainability Certifications, Trade Compliance Costs.

description: Abstract: The rapid liberalization of tariff barriers has elevated non-tariff measures (NTMs) to a central role in shaping global textile and apparel trade, yet rigorous, Vietnam-specific analyses of how European Union (EU) NTMs under the EVFTA affect Vietnamese exporters remain scarce. This study fills that gap by combining novel indices—Degree of Application, Frequency of Application, and Effectiveness—built on UNCTAD’s taxonomy with detailed HS 61–63 trade-flow data (2012–2024) and semi-structured interviews of exporters and certifying bodies. We quantify the incidence and intensity of key EU NTMs (REACH, EU Ecolabel, “yarn-forward” rules) and estimate their differentiated impacts on export prices, volumes, and product composition across firm sizes. Our findings reveal that large enterprises securing sustainability certifications achieve 15–25 percent price premiums and sustained volume growth in premium segments, whereas SMEs face 8–12 percent MFN duties and market exclusion when origin rules are unmet. We also document a structural shift toward higher-value, eco-friendly products—organic-cotton and recycled-fiber lines—driven by evolving EU sustainability mandates. By integrating quantitative NTM metrics with firm-level insights, this research contributes to the literature on trade protectionism by providing the first comprehensive assessment of EVFTA-era NTMs on Vietnam’s apparel sector and offers concrete policy recommendations to transform compliance burdens into competitive advantages.

description: We introduce a many body theory for thermal far-field emission of dipolar dielectric and metallic nanoparticles in the vicinity of a substrate within the framework of fluctuational electrodynamics. Our theoretical model includes the possibility to define the temperatures of each nanoparticle, the substrate temperature, and the temperature of the background thermal radiation, separately. To demonstrate the versatility of our method, we apply it in an exemplary way by discussing the thermal radiation of four particle assemblies of SiC and Ag nanoparticles above a planar SiC and Ag substrate. Furthermore, we use discrete dipole approximation to determine the thermal emission of a spherical nanoparticle in free space and close to a substrate. Finally, the calculation of the thermal far-field radiation of a sharp Si tip close to a SiC substrate using the discrete dipole approximation including the near-field scattering by the tip as well as the thermal emission of the tip and the contribution of the substrate which is partially blocked by the tip serves as another example.
The effects of variable retention harvesting on caribou terrestrial forage lichens : an exploration of silvicultural systems and their impacts on terrestrial lichen abundance
Creators: name: Weyman, Luke Ferris
Publisher: name: The University of British Columbia
Year: 2015

description: Northern caribou depend on terrestrial lichens as a primary source of food during winter. This paper illustrates how changes in harvesting intensity affect terrestrial lichen abundance, species richness and lichen mortality. Four silvicultural systems are examined; group selection, shelterwood, clearcut with reserves and clearcut with dispersed retention, and their impacts on terrestrial lichen communities discussed. It is determined that decreases in terrestrial lichen cover are correlated with removal of canopy cover, disturbances to the forest floor and the abundance of slash cover. Based on this relationship, the group selection silviculture system is most effective at maintaining terrestrial lichens while still allowing for timber removal.

description: The P2 experiment aims at high-precision measurements of the parity-violating asymmetry in elastic electron-proton and electron-$^{12}$C scatterings with longitudinally polarized electrons. We discuss here the sensitivity of P2 to leptoquarks, which within the P2 energy range can be described in the language of Standard Model Effective Field Theory (SMEFT). We give the expected P2 limits on the SMEFT operators and on the leptoquark parameters, which will test energy scales up to 15 TeV. In many cases those limits exceed current constraints from LHC and atomic parity violation (APV) experiments. We also demonstrate that degeneracies of different SMEFT operators can partially be resolved by use of APV experiments and different targets (protons and $^{12}$C) at P2. Moreover, we show that P2 could confirm or resolve potential tensions between the theoretical and experimental determinations of the weak charge of $^{133}$Cs.

description: We introduce a resetting Brownian bridge as a simple model to study search processes where the total search time $t_f$ is finite and the searcher returns to its starting point at $t_f$. This is simply a Brownian motion with a Poissonian resetting rate $r$ to the origin which is constrained to start and end at the origin at time $t_f$. We first provide a rejection-free algorithm to generate such resetting bridges in all dimensions by deriving an effective Langevin equation with an explicit space-time dependent drift $\tilde μ({\bf x},t)$ and resetting rate $\tilde r({\bf x}, t)$. We also study the efficiency of the search process in one-dimension by computing exactly various observables such as the mean-square displacement, the hitting probability of a fixed target and the expected maximum. Surprisingly, we find that there exists an optimal resetting rate $r^*$ that maximizes the search efficiency, even in the presence of a bridge constraint. We show however that the physical mechanism responsible for this optimal resetting rate for bridges is entirely different from resetting Brownian motions without the bridge constraint.

Irreversible Entropy Production rate in a parametrically driven-dissipative System: The Role of Self-Correlation between Noncommuting Observables

description: In this paper, we explore the emergence of the Wigner entropy production rate in the stationary state of a two-mode Gaussian system. The interacting modes dissipate into different local thermal baths. Also, one of the bosonic modes evolves into the squeezed-thermal state because of the parametric amplification process. Using the Heisenberg-Langevin approach, combined with quantum phase space formulation, we get an analytical expression for the steady-state Wigner entropy production rate. It contains two key terms. The first one is an Onsager-like expression that describes heat flow within the system. The second term resulted from vacuum fluctuations of the baths. Analyses show that self-correlation between the quadratures of the parametrically amplified mode pushes the mode towards the thermal squeezed state. It increases vacuum entropy production of the total system and reduces the heat current between the modes. The results imply that, unlike other previous proposals, squeezing can constrain the efficiency of actual non-equilibrium heat engines by irreversible flows.

description: Boiling is a complex phenomenon where different non-linear physical interactions take place and for which the quantitative modeling of the mechanism involved is not fully developed yet. In the last years, many works have been published focusing on the numerical analysis of this problem. However, a lack of numerical works assessing quantitatively the sensitivity of these numerical simulations to grid parameters can be identified, especially for the Lattice Boltzmann method (LBM). The main goal of this work is to propose a mesh refinement methodology for simulating phase-change heat transfer problems by means of the pseudopotential LBM. This methodology was based on relating the physical parameters to their lattice counterparts for an arbitrary mesh under the viscous regime (where $Δt \propto Δx ^2$). A suitable modification of the EOS parameters and the adjusting of thermodynamic consistency and surface tension for a certain $Δx$ were the main steps of the proposed methodology. A first ensemble of simple simulations including the droplet vaporization and the Stefan problems was performed to validate the proposed method and to assess the influence of some physical mechanisms. Global norms in space and time were used to evaluate the variations of both the density and temperature fields for pool boiling simulations when the lattice discretization is refined. It was observed that the proposed methodology provides convergent results for all the problems considered, and the convergence orders depend on the complexity of the simulated phenomena.
