description: The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz frequencies, yet a comprehensive description of their generation mechanisms is still lacking despite extensive efforts. Using terahertz emission spectroscopy, we investigate the generation of a coherent magnon mode in the van der Waals antiferromagnet NiPS$_3$ under a range of photoexcitation conditions. By tuning the pump photon energy from transparency to resonant with a $d$-$d$ transition, we reveal a striking change in the coherent magnon's dependence on the pump polarization, indicating two distinct excitation mechanisms. Our findings provide a strategy for the manipulation of magnetic modes via photoexcitation around sub-gap electronic states.

description: We investigate the real-time dynamics of the sub-Ohmic spin-boson model across a broad range of coupling strengths, using the numerically exact inchworm quantum Monte Carlo algorithm. From short- and intermediate-time dynamics starting from an initially decoupled state, we extract signatures of the zero-temperature quantum phase transition between localized and delocalized states. We show that the dynamical phase diagram thus obtained differs from the equilibrium phase diagram in both the values of critical couplings and the associated values of the critical exponent. We also identify and quantitatively analyze two competing mechanisms for the crossover between coherent oscillations and incoherent decay. Deep in the sub-Ohmic regime, the crossover is driven by the damping of the oscillation amplitude, while closer to the Ohmic regime the oscillation frequency itself drops sharply to zero at large coupling.

description: Based on the household livelihood endowment theory and the survey of 367 farmer households in Anhui, Hubei, and Sichuan in 2016, and using the orderly multi-category logistic model, the behavioral decision of farmers in the land circulation was discussed to find the key parameters influencing the land transfer-out. It found that decisions of farmers on land transfer-out behavior are affected by many factors. Specifically, household non-agricultural income and per capita land area significantly reduce farmers’ willingness to transfer land, while the household head age, agricultural input-output ratio, and confirmation of land right significantly promote the farmers’ decision on land transfer-out. Therefore, increasing the allocation efficiency of household livelihood endowment has important policy value and practical significance for eliminating unreasonable land circulation and promoting large-scale agricultural production.

description: In recent years, the land corruption in China is very serious. The amount of corruption cases is high, the links involved are various, harbor cases and fraud cases are many, the corruption subjects are mainly concentrated in government officials with high administrative level. The causes for land corruption include objective corruption opportunities and subjective corruption motivations. Only when information on land transfer is made public and accepted by the public, can it play a role in preventing land corruption.

description: We have used an electromigration technique to fabricate C$_{60}$-based single-molecule transistors. We detail the process statistics and the protocols used to infer the successful formation of a single-molecule transistor. At low temperatures each transistor acts as a single-electron device in the Coulomb blockade regime. Resonances in the differential conductance indicate vibrational excitations consistent with a known mode of C$_{60}$. In several devices we observe conductance features characteristic of the Kondo effect, a coherent many-body state comprising an unpaired spin on the molecule coupled by exchange to the conduction electrons of the leads. The inferred Kondo temperature typically exceeds 50 K, and signatures of the vibrational modes persist into the Kondo regime.

description: Geometric frustration in two-dimensional Ising models allows for a wealth of exotic universal behavior, both Ising and non-Ising, in the presence of quantum fluctuations. In particular, the triangular antiferromagnet and Villain model in a transverse field can be understood through distinct XY pseudospins, but have qualitatively similar phase diagrams including a quantum phase transition in the (2+1)-dimensional XY universality class. While the quantum dynamics of modestly-sized systems can be simulated classically using tensor-based methods, these methods become infeasible for larger lattices. Here we perform both classical and quantum simulations of these dynamics, where our quantum simulator is a superconducting quantum annealer. Our observations on the triangular lattice suggest that the dominant quench dynamics are not described by the quantum Kibble-Zurek scaling of the quantum phase transition, but rather a faster coarsening dynamics in an effective two-dimensional XY model in the ordered phase. Similarly, on the Villain model, the scaling exponent does not match the Kibble-Zurek expectation. These results demonstrate the ability of quantum annealers to simulate coherent quantum dynamics and scale beyond the reach of classical approaches.

description: In order to explore the effects of farmland quality evaluation on site selection of land consolidation projects, the methods of agricultural land use classification were used. Taking several project areas in Yanjin County of Henan Province as examples, the farmland quality before and after land consolidation projects was evaluated. The results indicate that under the conditions of reasonable site selection, the implementation of land consolidation projects can effectively improve the farmland quality and increase the grain productivity. Therefore, before the site selection for land consolidation projects, it is recommended to carry out pre-evaluation of farmland quality, and guide the project implementation according to the evaluation results. Besides, it is recommended to focus on medium and low level farmland with large centralized area, excellent original production conditions, but low level of development and use.

description: We present the HI data for 5 spiral galaxies that, along with their Halpha rotation curves, are used to derive the distribution of dark matter within these objects. A new method for extracting rotation curves from HI data cubes is presented; this takes into account the existence of a warp and minimises projection effects. The rotation curves obtained are tested by taking them as input to construct model data cubes that are compared to the observed ones: the agreement is excellent. On the contrary, the model data cubes built using rotation curves obtained with standard methods, such as the first-moment analysis, fail the test. The HI rotation curves agree well with the Halpha data, where they coexist. Moreover, the combined Halpha + HI rotation curves are smooth, symmetric and extended to large radii. The rotation curves are decomposed into stellar, gaseous and dark matter contributions and the inferred density distribution is compared to various mass distributions: dark haloes with a central density core, $Λ$ Cold Dark Matter ($Λ$CDM) haloes (NFW, Moore profiles), HI scaling and MOND. The observations point to haloes with constant density cores of size $r_{core} \sim r_{opt}$ and central densities scaling approximately as $ρ_0 \propto r_{core}^{-2/3}$. $Λ$CDM models (which predict a central cusp in the density profile) are in clear conflict with the data. HI scaling and MOND cannot account for the observed kinematics: we find some counter-examples.

description: Can the way one articulates information about food insecurity affect the way that people respond and act on said information? This study sought to investigate the effect of different information delivery methods, specifically a personalized testimonial or simply giving a mass of statistics to a participant and seeing whether or not the different ways information is conveyed affected the willingness of said participant to use food insecurity resources. We hypothesized that, based on past research, people would be more affected by the testimonial condition as it would be a more personable and identifiable effect. Through an online survey (n = 110) we randomly assigned UBC undergraduate students to a statistics condition, testimonial condition, or a control condition. An ANOVA was used following the data collection and no significant effect was found across the conditions. We associated this effect with insufficient food insecure participants as well as a floor effect in the questions asked. Following our research, we recommended that UBC conduct further research with a greater subject pool for a better understanding. We also recommend that those who advertise for Food Insecurity Resources focus less on the method they get their point across and more on the content.

description: In recent ten years in China,the application research of hypobaric storage was extended to the non-freeze preservation of cooked food, fresh-cut vegetables,edible fungi and fruits, preliminary processing of growing area and vacuum cold fresh chain to the cold chain breakage for horticultural products,and also to the investigation of principle and theory but the investigation results would have some evident difference. This paper will simply summarize the basic conception, principle, two withdrawing air type hypobaric storage technologies, and introduce many examples as mentioned above extending in China. This paper thinks that the master mechanism of preservation of LP for fresh horticultural products effectively inhibits the activity change of manifold enzymes, which are PAL, POD, PPO, CAT, CAD, SOD et al., affecting the maturation and caducity of fresh horticultural products during LP storage for a short period, as a result, to reduce both risk of physiology obstacle and disease and to prolong their postharvest life; for the foreseeable future Burg’s hypobaric storage technology and hypobaric short period treatment technology will play an important role in the preservation on fresh agricultural products and food preservation in storage and transportation, the preliminary processing of growing area, fresh logistics, establishing the operating platform of perishable food and high business value, fresh e-business, and fresh delivery for scattered families, establishing the operating platform of fresh-cut vegetables including edible fungi and so on in China or in the world.

description: We found signatures of current-induced sliding motion in helimagnetic $\mathrm{Mn}\mathrm{Au}_2$ thin films. An abrupt change in differential resistivity occurred at a threshold bias current in the helimagnetic state, whereas it was absent in the induced ferromagnetic state. Broadband voltage noise also emerged above the threshold current in the helimagnetic state. Based on the similarity to canonical charge/spin density wave systems, we ascribed the origin of these phenomena to the sliding motion of the helimagnetic structure.

Coronal element abundances of the post-common envelope binary V471 Tauri with ASCA

description: We report on ASCA observations of the coronally active companion star in the post-common envelope binary V471 Tauri. Evolutionary calculations indicate that there should be no peculiar abundances on the companion star resulting from the common envelope epoch. Indeed, we find no evidence for peculiar abundances, although uncertainties are high. We find that a single-temperature plasma model does not fit the data. Two-temperature models with decoupled elemental abundances suggest that Fe is underabundant compared to the Hyades photospheric mean. In the absence of a measurement of photospheric Ne abundance in the cluster, we find Ne is overabundant compared to the solar photospheric value. This is indicative of the inverse first ionization potential effect. Differences between coronal and photospheric abundances are believed to result from the fractionation of ionized and neutral material in the upper atmosphere of the star.

Apesar de a conferência ter decorrido em 2010, são bem atuais as questões levantadas por estas comunicações: em que medida as bibliotecas beneficiarão das Redes Sociais? Será que as redes sociais permitem às bibliotecas alcançar, facilmente e de forma eficaz, outros públicos e diferentes? Como construir a mensagem em canais como o Facebook, o Hi5 ou o Flickr? O tema foi atualizado com um texto de Paulo Leitão sobre os Wikis, onde é analisada a importância da gestão de conteúdos numa relação com os utilizadores das bibliotecas. E, porque hoje em dia um dos temas da atualidade é o papel social da biblioteca – que será também um dos temas do Congresso da BAD em outubro – partilhamos consigo uma tomada de posição da EBLIDA: Bibliotecas – Pólos Culturais de Informação e Inspiração. Do universo dos arquivos apresentamos-lhe duas faces desse universo. Uma face que nos é dada pelos profissionais diretamente envolvidos, com dois artigos que nos dão uma visão bastante completa das principais questões que se colocam à atual rede nacional de arquivos e qual o contributo da DGARQ para a consolidação e desenvolvimento dessa rede. A outra face é-nos dada pela perspetiva do utilizador, com um testemunho do jornalista Joaquim Furtado Em Louvor dos Arquivos, apresentado na Cinemateca Nacional, no dia 27 de outubro de 2011, numa sessão organizada conjuntamente pelo Centro Nacional de Cultura e pela BAD para comemorar o Dia Mundial do Património Audiovisual, proclamado pela UNESCO. A completar esta edição, uma recensão crítica sobre o último número editado pela revista «Páginas a&b», e ainda um in memoriam em que se evoca uma colega de Espinho, Beatriz Matos Fernandes, arquivista apaixonada, de quem os colegas recordam a incansável vitalidade, o entusiasmo e, sobretudo, o profissionalismo.

description: Recursive graph queries are increasingly popular for extracting information from interconnected data found in various domains such as social networks, life sciences, and business analytics. Graph data often come with schema information that describe how nodes and edges are organized. We propose a type inference mechanism that enriches recursive graph queries with relevant structural information contained in a graph schema. We show that this schema information can be useful in order to improve the performance when evaluating acylic recursive graph queries. Furthermore, we prove that the proposed method is sound and complete, ensuring that the semantics of the query is preserved during the schema-enrichment process.

description: Genus Bukhkalius Kirejtshuk & Jarzembowski, 2020
 Type species: Tetraphalerus lindae Jarzembowski, Wang & Zheng, 2017.
 Revised diagnosis: Body elongate. Head moderately elongate; temples short; antennal grooves short, only reaching anterior margin of eyes; antennae short, subfiliform; separate mentum present. Pronotal disc without protuberances or ridges; propleura not reaching anterior prothoracic margin; procoxae contiguous. Elytra with indistinct longitudinal ridges (primary veins); lateral edge of elytra with double rows of teeth. Abdominal ventrites abutting.
 Bukhkalius differs from Tetraphalerus in head only moderately elongate, antennal grooves incomplete, and mushroom-shaped micro-tubercles absent. Bukhkalius differs from the remaining genera in Ommatidae in the combination of antennal grooves present (though incomplete), separate mentum present, and propleura not reaching anterior prothoracic margin.
 Remarks: The diagnosis provided in Kirejtshuk(2020) was insufficient, which cannot really differentiate Bukhkalius from Omma and Omma -like genera. For example, he claimed that “this new genus [Bukhkalius] differs from the genera with subglobous prothorax (Cionocoleus, Cionocups, Omma, Polyakius and Rhopalomma) in the clear ‘neck’ of the head”. However, neck is clearly present in both extant (Escalona et al., 2020) and fossil ommatines. The neck in some fossil Omma (Figs. 4B, C) could be even narrower than that of Bukhkalius.

Evaporative Cooling of Helium Nanodroplets with Angular Momentum Conservation
Creators: name: Lehmann, Kevin K.

Year: 2003

subject: FOS: Physical sciences

description: Evaporative cooling of helium nanodroplets is studied with a statistical rate model that includes, for the first time, angular momentum conservation as a constraint on the accessible droplet states. It is found that while the final temperature of the droplets is almost identical to that previously predicted and later observed, the distribution of total droplet energy and angular momentum states is vastly more excited than a canonical distribution at the same temperature. It is found that the final angular momentum of the droplets is highly correlated with the initial direction, and that a significant fraction of the alignment of the total angular momentum should be transferred to the rotational angular momentum of an embedded molecule.

description: This study introduces DrivAerNet, a large-scale high-fidelity CFD dataset of 3D industry-standard car shapes, and RegDGCNN, a dynamic graph convolutional neural network model, both aimed at aerodynamic car design through machine learning. DrivAerNet, with its 4000 detailed 3D car meshes using 0.5 million surface mesh faces and comprehensive aerodynamic performance data comprising of full 3D pressure, velocity fields, and wall-shear stresses, addresses the critical need for extensive datasets to train deep learning models in engineering applications. It is 60\% larger than the previously available largest public dataset of cars, and is the only open-source dataset that also models wheels and underbody. RegDGCNN leverages this large-scale dataset to provide high-precision drag estimates directly from 3D meshes, bypassing traditional limitations such as the need for 2D image rendering or Signed Distance Fields (SDF). By enabling fast drag estimation in seconds, RegDGCNN facilitates rapid aerodynamic assessments, offering a substantial leap towards integrating data-driven methods in automotive design. Together, DrivAerNet and RegDGCNN promise to accelerate the car design process and contribute to the development of more efficient cars. To lay the groundwork for future innovations in the field, the dataset and code used in our study are publicly accessible at https://github.com/Mohamedelrefaie/DrivAerNet.

description: Na sociedade atual em que os serviços Web 2.0 são omnipresentes, quer pelo numero e funcionalidades que oferecem, quer pela elevada adesão as mesmas (transversalmente a todos os tipos de utilizadores), já não se questiona a importância da sua adoção pelas Bibliotecas. Pode-se e deve-se contudo questionar como as promover e manter, de modo a potenciar a missão da Biblioteca como elemento enriquecedor da Comunidade que serve, explorando as sinergias resultantes das interações associadas as atividades, sejam elas pró-ativas ou passivas, junto da Comunidade (dando e recebendo da mesma). Algumas soluções, comerciais ou Open Source, oferecem já componentes Web 2.0 no cenário da descoberta de informação. Estes componentes e o ambiente participativo e colaborativo associado ao seu uso podem ajudar no enriquecimento de sistemas de pesquisa e recuperação de informação, promovendo a Inteligência Coletiva pela partilha de informação revestida de conhecimento e avaliando os recursos encontrados, de modo a que os utilizadores seguintes, ao efetuarem uma pesquisa semelhante, obtenham em primeiro lugar os resultados mais pertinentes (ciclo “Procurar > Encontrar > Avaliar > Compreender > Partilhar”). Nesta comunicação e apresentado um modelo em que não apenas o documento e elemento de referencia mas, para alem dele, devera ser também o utilizador em si e toda a sua envolvente (atividades e informação associada ao seu perfil ou comunidades a que pertença), assumindo uma dimensão crucial na geração de informação adicional pelos próprios utilizadores o sistema, com possíveis mais-valias na criação e identificação de comunidades de utilizadores com interesses comuns.

description: The intrinsic valley degree of freedom makes bilayer graphene (BLG) a unique platform for semiconductor qubits. The single-carrier quantum dot (QD) ground state exhibits a two-fold degeneracy, where the two states that constitute a Kramers pair, have opposite spin and valley quantum numbers. Because of the valley-dependent Berry curvature, an out-of-plane magnetic field breaks the time-reversal symmetry of this ground state and a qubit can be encoded in the spin-valley subspace. The Kramers states are protected against known spin- and valley-mixing mechanisms because mixing requires a simultaneous change of both quantum numbers. Here, we fabricate a tunable QD device in Bernal BLG and measure a spin-valley relaxation time for the Kramers states of ${38~\mathrm{s}}$, which is two orders of magnitude longer than the ${0.4~\mathrm{s}}$ measured for purely spin-blocked states. We also show that the intrinsic Kane-Mele spin-orbit splitting enables a Kramers doublet single-shot readout even at zero magnetic field with a fidelity above ${99\%}$. If these long-lived Kramers states also possess long coherence times and can be effectively manipulated, electrostatically defined QDs in BLG may serve as long-lived semiconductor qubits, extending beyond the spin qubit paradigm.

Electron-electron interaction effects on optical excitations in semiconducting single-walled carbon nanotubes

Year: 2004
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We report correlated-electron calculations of optically excited states in ten semiconducting single-walled carbon nanotubes with a wide range of diameters. Optical excitation occurs to excitons whose binding energies decrease with the increasing nanotube diameter, and are smaller than the binding energy of an isolated strand of poly-(paraphenylene vinylene). The ratio of the energy of the second optical exciton polarized along the nanotube axis to that of the lowest exciton is smaller than the value predicted within single-particle theory. The experimentally observed weak photoluminescence is an intrinsic feature of semiconducting nanotubes, and is consequence of dipole-forbidden excitons occurring below the optical exciton.

Highlighting the Benefits of Bird Friendly Certified Coffee : Which Works Best?

description: This study explores the awareness of Bird Friendly© Coffee (BFC) as well as the relationship between different benefits of BFC (aid to farmers, birds/environment, personal health) and purchasing attitudes towards BFC products among UBC students. More specifically, we wanted to explore if highlighting different benefits of BFC will increase students’ willingness to purchase the product. We distributed a self-reporting survey to UBC students and asked if they were familiar with the BFC logos prior. We also provided specific information on each benefit of BFC before asking them how willing they were to purchase the products. Due to the lack of demand for BFC, we hypothesized that most UBC students (more than 50%) are unaware of BFC. Knowing that people prioritize self-benefit messages over non-self-benefit messages, we also hypothesized that the highest increase in willingness to purchase BFC would occur when highlighting the personal health benefits associated with it (compared to farmers and nature). Results show that 92.68% of UBC students were unaware of BFC prior to the study. Willingness to purchase BFC did not significantly differ between different BFC benefit conditions. However, there was a significant difference in purchase willingness between coffee drinkers and non-coffee drinkers.

description: Motivated by the minimal tower problem, an earlier work studied diagonalizations of covers where the covers are related to linear quasiorders (tau-covers). We deal with two types of combinatorial questions which arise from this study. 1. Two new cardinals introduced in the topological study are expressed in terms of well known cardinals characteristics of the continuum. 2. We study the additivity numbers of the combinatorial notions corresponding to the topological diagonalization notions. This gives new insights on the structure of the eventual dominance ordering on the Baire space, the almost inclusion ordering on the Rothberger space, and the interactions between them.
