description: The theory of enterprise value management was applied to the performance evaluation of the discipline construction members in colleges and universities, and a value evaluation model of performance was established. Then, using the analytic hierarchy process (AHP) and quantitative research method, it evaluated the cost of the discipline construction members and the functions realized. Finally, it determined the performance value level and came up with the value optimization recommendations.

description: We employ dual-gated 30°-twisted bilayer graphene to demonstrate simultaneous ultra-high mobility and conductivity (up to 40 mS at room temperature), unattainable in a single-layer of graphene. We find quantitative agreement with a simple phenomenology of parallel conduction between two pristine graphene sheets, with a gate-controlled carrier distribution. Based on the parallel transport mechanism, we then introduce a method for in situ measurements of the chemical potential of the two layers. This twist-enabled approach, neither requiring a dielectric spacer, nor separate contacting, has the potential to greatly simplify the measurement of thermodynamic quantities in graphene-based systems of high current interest.

description: Recent advances in image captioning have focused on enhancing accuracy by substantially increasing the dataset and model size. While conventional captioning models exhibit high performance on established metrics such as BLEU, CIDEr, and SPICE, the capability of captions to distinguish the target image from other similar images is under-explored. To generate distinctive captions, a few pioneers employed contrastive learning or re-weighted the ground-truth captions. However, these approaches often overlook the relationships among objects in a similar image group (e.g., items or properties within the same album or fine-grained events). In this paper, we introduce a novel approach to enhance the distinctiveness of image captions, namely Group-based Differential Distinctive Captioning Method, which visually compares each image with other images in one similar group and highlights the uniqueness of each image. In particular, we introduce a Group-based Differential Memory Attention (GDMA) module, designed to identify and emphasize object features in an image that are uniquely distinguishable within its image group, i.e., those exhibiting low similarity with objects in other images. This mechanism ensures that such unique object features are prioritized during caption generation for the image, thereby enhancing the distinctiveness of the resulting captions. To further refine this process, we select distinctive words from the ground-truth captions to guide both the language decoder and the GDMA module. Additionally, we propose a new evaluation metric, the Distinctive Word Rate (DisWordRate), to quantitatively assess caption distinctiveness. Quantitative results indicate that the proposed method significantly improves the distinctiveness of several baseline models, and achieves state-of-the-art performance on distinctiveness while not excessively sacrificing accuracy...

description: Nuclear level densities for $^{56,57}$Fe have been extracted from the primary $γ$-ray spectra using ($^3$He,$^3$He$^{\prime}γ$) and ($^3$He,$αγ$) reactions. Nuclear thermodynamic properties for $^{56}$Fe and $^{57}$Fe are investigated using the experimental level densities. These properties include entropy, Helmholtz free energy, caloric curves, chemical potential, and heat capacity. In particular, the breaking of Cooper pairs and single-quasiparticle entropy are discussed and shown to be important concepts for describing nuclear level density. Microscopic model calculations are performed for level densities of $^{56,57}$Fe. The experimental and calculated level densities are compared. The average number of broken Cooper pairs and the parity distribution are extracted as a function of excitation energy for $^{56,57}$Fe from the model calculations.

description: In the existing research at home and abroad, the construction of extracurricular learning platform is still only focused on solving the problems of curriculum learning itself. At the same time, there are no cases of multiple linkage effects, including integrating alumni resources, promoting the construction of alumni association, promoting students' internship and employment, strengthening ties with enterprises and so on. On the basis of the original function of the alumni management system, this paper expands the sections and adds the main body of students to enrich the functions of the platform. This paper constructs a fully-participatory extracurricular learning platform with multiple linkage effect, which provides a reference for other majors inside and outside the school to establish extracurricular learning platform.

description: The flagship measurement of the JUNO experiment is the determination of the neutrino mass ordering. Here we revisit its prospects to make this determination by 2030, using the current global knowledge of the relevant neutrino parameters as well as current information on the reactor configuration and the critical parameters of the JUNO detector. We pay particular attention to the non-linear detector energy response. Using the measurement of $θ_{13}$ from Daya Bay, but without information from other experiments, we estimate the probability of JUNO determining the neutrino mass ordering at $\ge$ 3$σ$ to be 31% by 2030. As this probability is particularly sensitive to the true values of the oscillation parameters, especially $Δm^2_{21}$, JUNO's improved measurements of $\sin^2 θ_{12}$, $Δm^2_{21}$ and $|Δm^2_{ee}|$, obtained after a couple of years of operation, will allow an updated estimate of the probability that JUNO alone can determine the neutrino mass ordering by the end of the decade. Combining JUNO's measurement of $|Δm^2_{ee}|$ with other experiments in a global fit will most likely lead to an earlier determination of the mass ordering.

description: We investigate the ability of the Laser Interferometer Space Antenna (LISA) to detect a stochastic gravitational-wave background (GWB) produced by cosmic strings, and to subsequently estimate the string tension $Gμ$ in the presence of instrument noise, an astrophysical background from compact binaries, and the galactic foreground from white dwarf binaries. Fisher Information and Markov Chain Monte Carlo methods provide estimates of the LISA noise and the parameters for the different signal sources. We demonstrate the ability of LISA to simultaneously estimate the galactic foreground, as well as the astrophysical and cosmic string produced backgrounds. Considering the expected astrophysical background and a galactic foreground, a cosmic string tension in the $G μ\approx 10^{-16}$ to $Gμ\approx 10^{-15}$ range or bigger could be measured by LISA, with the galactic foreground affecting this limit more than the astrophysical background. The parameter estimation methods presented here can be applied to other cosmological backgrounds in the LISA observation band.

description: In the process of ideological and political education, improving the timeliness of ideological and political education is a hot issue in theoretical research, and it has long been concerned by academic circles. This paper analyzes and discusses the factors that affect the study effect of ideological and political students in colleges and universities, which is of great theoretical and practical significance to improve the effectiveness of ideological and political education. At present, under the influence of the social environment, bad peer groups, network environment and insufficient practical and participatory teaching, ideological and political education in colleges and universities still have some problems such as weak effectiveness. In addition to the limitation of college students' social experience and the incongruity of physical and mental development, it is easy to produce negative attitudes towards ideological and political education in the age group which is prone to adverse psychology. These factors have greatly affected the effect of ideological and political education in colleges and universities.

description: As the year 2020 came to a close, several new strains have been reported for the SARS-CoV-2 coronavirus, the agent responsible for the COVID-19 pandemic that has afflicted us all this past year. However, it is difficult to comprehend the scale, in sequence space, geographical location and time, at which SARS-CoV-2 mutates and evolves in its human hosts. To get an appreciation for the rapid evolution of the coronavirus, we built interactive scalable vector graphics (SVG) maps that show daily nucleotide variations in genomes from the six most populated continents compared to that of the initial, ground-zero SARS-CoV-2 isolate sequenced at the beginning of the year. The attached compressed file package comprises SARS-CoV-2 mutation timemaps SVG files for 2020 and 2021, updated with data submitted to GISAID as of January 25th 2021 (inclusive). It is a snapshot of the webpage hosting these maps (https://bcgsc.github.io/SARS2) on that day and includes the script and single nucleotide variation (SNV) report files used to generate these and could be used by anyone to generate additional and custom interactive SVG maps. It supplements our F1000research article. The frequently updated and comprehensive SARS-CoV-2 genome SNV reports (https://www.bcgsc.ca/downloads/btl/SARS-CoV-2/mutations) represent a wealth of information that could be mined to gain further insights into the rapid SARS-CoV-2 coronavirus evolution in human hosts.

Our main results include a quadratic bound on the diameter of axial 3-way transportation polytopes and a catalogue of non-degenerate transportation polytopes of small sizes. The catalogue disproves five conjectures about these polyhedra stated in the monograph by Yemelichev et al. (1984). It also allowed us to discover some new results. For example, we prove that the number of vertices of an $m\times n$ transportation polytope is a multiple of the greatest common divisor of $m$ and $n$.

description: Flat-space cosmologies (FSC) are solutions to three dimensional theories of gravity without cosmological constant that have cosmological horizons. A detector located near the time-like singularity of the spacetime can absorb Hawking modes that are created near the horizon. Continuation of this process will eventually cause the entropy of the radiation to be larger than the entropy of the FSC, which leads to the information paradox. In this paper, we resolve this paradox for the FSC using the island proposal. To do this, we couple an auxiliary flat bath system to this spacetime in timelike singularity so that Hawking modes are allowed to enter the bath and the entropy of radiation can be measured in its asymptotic region where gravity is also weak. We show that adding island regions that receive the partners of Hawking modes cause the entropy of radiation to follow a Page curve which leads to resolving the information paradox. Moreover, we design a quantum teleportation protocol by which one can extract the information residing in islands.

description: We investigate transport in weakly-coupled metal nanoparticle arrays, focusing on the regime where tunneling is competing with strong single electron charging effects. This competition gives rise to an interplay between two types of charge transport. In sequential tunneling, transport is dominated by independent electron hops from a particle to its nearest neighbor along the current path. In inelastic cotunneling, transport is dominated by cooperative, multi-electron hops that each go to the nearest neighbor but are synchronized to move charge over distances of several particles. In order to test how the temperature-dependent cotunnel distance affects the current-voltage ($I-V$) characteristics we perform a series of systematic experiments on highly-ordered, close-packed nanoparticle arrays. The arrays consist of $\sim 5.5$nm diameter gold nanocrystals with tight size dispersion, spaced $\sim 1.7$nm apart by interdigitating shells of dodecanethiol ligands. We present $I-V$ data for mono-, bi-, tri- and tetralayer arrays. For stacks 2-4 layers thick we compare in-plane measurements with data for vertical transport, perpendicular to the array plane. Our results support a picture whereby transport inside the Coulomb blockade regime occurs by inelastic cotunneling, while sequential tunneling takes over at large bias above the global Coulomb blockade threshold $V_t(T)$, and at high temperatures.

description: We study the possibility of measuring neutrino Yukawa couplings in the Next-to-Minimal Supersymmetric Standard Model with right-handed neutrinos (NMSSMr) when the lightest right-handed sneutrino is the Dark Matter (DM) candidate, by exploiting a `dijet + dilepton + Missing Transverse Energy' signature. We show that, contrary to the miminal realisation of Supersymmetry (SUSY), the MSSM, wherein the DM candidate is typically a much heavier (fermionic) neutralino state, this extended model of SUSY offers one with a much lighter (bosonic) state as DM that can then be produced at the next generation of $e^+e^-$ colliders with energies up to 500 GeV or so. The ensuing signal, energing from chargino pair production and subsequent decay, is extremely pure so it also affords one with the possibility of extracting the Yukawa parameters of the (s)neutrino sector. Altogether, our results serve the purpose of motivating searches for light DM signals at such machines, where the DM candidate can have a mass around the electroweak scale.

description: Based on consideration of the system symmetry and its Hilbert space, we show that strongly interacting fermions in an optical lattice or superlattice can be generically described by a lattice resonance Hamiltonian. The latter can be mapped to a general Hubbard model with particle assisted tunneling rates. We investigate the model under population imbalance and show the attractive and the repulsive models have the same complexity in phase diagram under the particle-hole mapping. Using this mapping, we propose an experimental method to detect possible exotic superfluid/magnetic phases for this system.

description: We investigate the thermalization of Sachdev-Ye-Kitaev (SYK) models coupled via random interactions following quenches from the perspective of entanglement. Previous studies have shown that when a system of two SYK models coupled by random two-body terms is quenched from the thermofield double state with sufficiently low effective temperature, the Rényi entropies do not saturate to the expected thermal values in the large-$N$ limit. Using numerical large-$N$ methods, we first show that the Rényi entropies in a pair SYK models coupled by two-body terms can thermalize, if quenched from a state with sufficiently high effective temperature, and hence exhibit state-dependent thermalization. In contrast, SYK models coupled by single-body terms appear to always thermalize. We provide evidence that the subthermal behavior in the former system is likely a large-$N$ artifact by repeating the quench for finite $N$ and finding that the saturation value of the Rényi entropy extrapolates to the expected thermal value in the $N \to \infty$ limit. Finally, as a finer grained measure of thermalization, we compute the late-time spectral form factor of the reduced density matrix after the quench. While a single SYK dot exhibits perfect agreement with random matrix theory, both the quadratically and quartically coupled SYK models exhibit slight deviations.

Nucleon Tensor Charge from Exclusive $π^o$ Electroproduction

description: Exclusive $π^o$ electroproduction from nucleons is suggested for extracting the tensor charge and other quantities related to transversity from experimental data. This process isolates C-parity odd and chiral odd combinations of t-channel exchange quantum numbers. In a hadronic picture it connects the meson production amplitudes to C-odd Regge exchanges with final state interactions. In a description based on partonic degrees of freedom, the helicity structure for this C-odd process relates to the quark helicity flip, or chiral odd generalized parton distributions. This differs markedly from deeply virtual Compton scattering, and both vector meson and charged $π$ electroproduction, where the axial charge can enter the amplitudes. Contrarily the tensor charge enters the $π^o$ process. The connection through the helicity description of the process to both the partonic and hadronic perspectives is studied and exploited in model calculations to indicate how the tensor charge and other transversity parameters can be related to cross section and spin asymmetry measurements over a broad range of kinematics.

description: In this study, considering that the $Ξ_b (6227)$ state is in molecular structure, the magnetic moment of this state is extracted in the light-cone QCD sum rules. The numerical result is obtained as $μ_{Ξ_b}= 0.12 \pm 0.03~μ_N$. The magnetic moment of this state contains important information of its internal structure and shape deformations. Measurement of the magnetic moment of the $Ξ_b(6227)$ state in future experimental facilities can be very helpful in identification of the quantum numbers, as well as comprehension of the inner structure of this state.

description: Die informelle Pflege und Betreuung von Menschen am Lebensende ist ein Bereich, der auf vielfältige Weise geprägt ist von geschlechtsspezifischen Vorstellungen, Zuschreibungen und Normen. Der vorliegende Beitrag geht auf der Grundlage einer aktuellen Studie zu den Erfahrungen, Bedürfnissen, Sorgen und Ressourcen pflegender Angehöriger der Frage nach, inwiefern geschlechtsspezifische Zuschreibungen die Erfahrungen pflegender Frauen und Männer beeinflussen. Dabei wird deutlich, dass pflegende Männer gemäß der bis heute dominierenden klassischen Rollenverteilung zwar seltener sind, gleichzeitig aber auch mehr Anerkennung und Unterstützung erhalten – nicht zuletzt von den Fachpersonen des Gesundheitswesens. Während in ihren Narrativen die Übernahme der als weiblich konnotierten pflegerischen Handlungen viel stärker thematisiert wird als bei den Frauen, betonen diese vielmehr die „Natürlichkeit“ ihrer Tätigkeit, stehen damit aber auch unter einem viel größeren Druck. Die informelle Pflege am Lebensende ist für die Pfl egenden – Männer wie Frauen – mit hohen Belastungen verbunden. Weil diese Belastungen aber unterschiedlich erlebt werden, ist ein Bewusstsein für die machtvollen Zuschreibungen und Geschlechterbilder, die sich in Normen und Handlungen perpetuieren, unabdingbar für eine gendergerechte Politik und Praxis.

description: In this work, we calculate the higher mass spectra for the $2S$- and $1D$-wave fully-charmed and fully-bottom tetraquark states in a nonrelativistic potential quark model. The $2S$-wave fully-charmed/bottom tetraquark states lie in the mass range of $\sim (6.9,7.1)$/$(19.7,19.9)$ GeV, apart for the highest $0^{++}$ state $T_{(cc\bar{c}\bar{c})0^{++}}(7185)$/ $T_{(bb\bar{b}\bar{b})0^{++}}(19976)$. Most of the $2S$-wave states highly overlap with the high-lying $1P$-wave states. The masses for the $1D$-wave fully-charmed/bottom tetraquarks are predicted to be in the range of $\sim (6.7,7.2)/(19.5,20.0)$ GeV. The mass range for the $D$-wave tetraquark states cover most of the mass range of the $P$-wave states and the whole mass range of the $2S$-wave states. The narrow structure $X(6900)$ recently observed at LHCb in the di-$J/ψ$ invariant mass spectrum may be caused by the $1P$-, or $2S$-, or $1D$-wave $T_{cc\bar{c}\bar{c}}$ states. The vague structure $X(7200)$ may be caused by the highest $2S$-wave state $T_{(cc\bar{c}\bar{c})0^{++}}(7185)$, two low-lying $3S$-wave states $T_{(cc\bar{c}\bar{c})0^{++}}(7240)$ and $T_{(cc\bar{c}\bar{c})2^{++}}(7248)$, and/or the high-lying $1D$-wave states with masses around 7.2 GeV and $J^{PC}=0^{++},1^{++},2^{++},3^{++}$, or $4^{++}$. While it is apparent that the potential quark model calculations predict more states than the structures observed in the di-$J/ψ$ invariant mass spectrum, our calculations will help further understanding of the properties of these fully-heavy tetraquark states in their strong and magnetic interactions with open channels based on explicit quark model wave functions.

description: As the year 2020 came to a close, several new strains have been reported for the SARS-CoV-2 coronavirus, the agent responsible for the COVID-19 pandemic that has afflicted us all this past year. However, it is difficult to comprehend the scale, in sequence space, geographical location and time, at which SARS-CoV-2 mutates and evolves in its human hosts. To get an appreciation for the rapid evolution of the coronavirus, we built interactive scalable vector graphics (SVG) maps that show daily nucleotide variations in genomes from the six most populated continents compared to that of the initial, ground-zero SARS-CoV-2 isolate sequenced at the beginning of the year. The attached compressed file package comprises SARS-CoV-2 mutation timemaps SVG files for 2020 and 2021, updated with data submitted to GISAID as of February 5th 2021 (inclusive). It is a snapshot of the webpage hosting these maps (https://bcgsc.github.io/SARS2) on that day and includes the script and single nucleotide variation (SNV) report files used to generate these and could be used by anyone to generate additional and custom interactive SVG maps. It supplements our F1000research article. The frequently updated and comprehensive SARS-CoV-2 genome SNV reports (https://www.bcgsc.ca/downloads/btl/SARS-CoV-2/mutations) represent a wealth of information that could be mined to gain further insights into the rapid SARS-CoV-2 coronavirus evolution in human hosts.

Percolation for the Vacant Set of Random Interlacements

description: We investigate random interlacements on Z^d, d bigger or equal to 3. This model recently introduced in arXiv:0704.2560 corresponds to a Poisson cloud on the space of doubly infinite trajectories modulo time-shift tending to infinity at positive and negative infinite times. A non-negative parameter u measures how many trajectories enter the picture. Our main interest lies in the percolative properties of the vacant set left by random interlacements at level u. We show that for all d bigger or equal to 3 the vacant set at level u percolates when u is small. This solves an open problem of arXiv:0704.2560, where this fact has only been established when d is bigger or equal to 7. It also completes the proof of the non-degeneracy in all dimensions d bigger or equal to 3 of the critical parameter introduced in arXiv:0704.2560.

A study on the biosynthesis of camphor
Creators: name: Atlay, Thérèse Mary
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes an investigation of the biosynthesis of camphor. Camphor, a bicyclic monoterpene, has been shown to be bio-synthesised from.geranyl pyrophosphate or its isomers (neryl pyrophosphate or linaloyl pyrophosphate) and several mechanisms have been proposed for this cyclisation process. [diagrams not included] In an attempt to differentiate the origin of the C(8) and C(9) methyl groups,, feeding experiments with appropriately labelled pre- cursors were attempted. The two precursors used were [2-²H₂]-mevalonic acid and [8-²H₁]-linalool. It was shown that the expected products, [8-²H₁]- and [9-²H₁]-camphor, could be differentiated by ²H-n.m.r. using the shift reagent Eu(thd)₃ (Eu(thd)₃ = tris(2,2,6,6-tetramethyl- 3,5-heptanedionato)europium) . Feeding experiments with Rosemarinus officanalis using the cut stem method showed no incorporation of deuterium label into camphor extracted from the plant's essential oil. [diagrams not included]
Reconstructing occluded Elevation Information in Terrain Maps with Self-supervised Learning

description: Accurate and complete terrain maps enhance the awareness of autonomous robots and enable safe and optimal path planning. Rocks and topography often create occlusions and lead to missing elevation information in the Digital Elevation Map (DEM). Currently, these occluded areas are either fully avoided during motion planning or the missing values in the elevation map are filled-in using traditional interpolation, diffusion or patch-matching techniques. These methods cannot leverage the high-level terrain characteristics and the geometric constraints of line of sight we humans use intuitively to predict occluded areas. We introduce a self-supervised learning approach capable of training on real-world data without a need for ground-truth information to reconstruct the occluded areas in the DEMs. We accomplish this by adding artificial occlusion to the incomplete elevation maps constructed on a real robot by performing ray casting. We first evaluate a supervised learning approach on synthetic data for which we have the full ground-truth available and subsequently move to several real-world datasets. These real-world datasets were recorded during exploration of both structured and unstructured terrain with a legged robot, and additionally in a planetary scenario on Lunar analogue terrain. We state a significant improvement compared to the baseline methods both on synthetic terrain and for the real-world datasets. Our neural network is able to run in real-time on both CPU and GPU with suitable sampling rates for autonomous ground robots. We motivate the applicability of reconstructing occlusion in elevation maps with preliminary motion planning experiments.

The competition of hydrogen-like and isotropic interactions on polymer collapse

description: We investigate a lattice model of polymers where the nearest-neighbour monomer-monomer interaction strengths differ according to whether the local configurations have so-called ``hydrogen-like'' formations or not. If the interaction strengths are all the same then the classical $θ$-point collapse transition occurs on lowering the temperature, and the polymer enters the isotropic liquid-drop phase known as the collapsed globule. On the other hand, strongly favouring the hydrogen-like interactions give rise to an anisotropic folded (solid-like) phase on lowering the temperature. We use Monte Carlo simulations up to a length of 256 to map out the phase diagram in the plane of parameters and determine the order of the associated phase transitions. We discuss the connections to semi-flexible polymers and other polymer models. Importantly, we demonstrate that for a range of energy parameters two phase transitions occur on lowering the temperature, the second being a transition from the globule state to the crystal state. We argue from our data that this globule-to-crystal transition is continuous in two dimensions in accord with field-theory arguments concerning Hamiltonian walks, but is first order in three dimensions.
