description: Starting with a hidden local symmetry Lagrangian at the vector manifestation (VM) fixed point that incorporates heavy-quark symmetry and matching the bare theory to QCD, we calculate the splitting of chiral doublers of heavy-light mesons proposed by Nowak, Rho and Zahed, and Bardeen and Hill. We show, in the three-flavor chiral limit, that the splitting is directly proportional to the light-quark condensate and comes out to be \sim (1/3) m_N where m_N is the nucleon mass, implying that the splitting vanishes in the chiral limit at the chiral restoration point -- temperature T_c, density n_c or number of flavors N_F^c. The result turns out to be surprisingly simple with the vector (ρ) meson playing the crucial role in quantum corrections, pointing to the relevance of the VM to QCD in the way chiral symmetry is manifested in hadronic matter. We also make predictions on the hadronic decay processes of the excited heavy (charm) -light mesons \tilde{D}.

description: We experimentally investigate Josephson current between two 5~$μ$m spaced superconducting indium leads, coupled to a NiTe$_2$ single crystal flake, which is a type-II Dirac semimetal. Under microwave irradiation, we demonstrate a.c. Josephson effect at millikelvin temperatures as a number of Shapiro steps. In addition to the integer ($n=1,2,3,4...$) steps, we observe fractional ones at half-integer values $n=1/2,3/2,5/2$ and 7/2, which corresponds to $π$ periodicity of current-phase relationship. In contrast to previous investigations, we do not observe $4π$ periodicity (disappearance of the odd $n=1,3,5...$ Shapiro steps), while the latter is usually considered as a fingerprint of helical surface states in Dirac semimetals and topological insulators. We argue, that our experiment confirms Josephson current through the topological hinge states in NiTe$_2$: since one can exclude bulk supercurrent in 5~$μ$m long Josephson junctions, interference of the hinge modes is responsible for the $π$ periodicity, while stable odd Shapiro steps reflect chiral character of the topological hinge states.

description: Dynamic Light Scattering (DLS) measurements were performed on colloidal suspensions of Laponite\textsuperscript{\textregistered} at different concentrations in the range $C_\text{w}= (1.5÷3.0)$%. The slowing down of the dynamics induced by aging was monitored by following the temporal evolution of autocorrelation functions at different concentrations towards the gel and glass transition. Exploiting analogies with supercooled liquids approaching their glass transitions, an Angell plot for the structural relaxation times was drawn. Finally, the fragility of Laponite\textsuperscript{\textregistered} suspensions at different concentrations, in different solvents, at two salt concentrations and with the addition of a polymer was reported and discussed.

description: Les plateformes d’innovation (PI) sont perçues aujourd’hui comme les approches les plus adéquates de développement et de promotion des innovations agricoles. Mais la plupart des précédentes études se sont focalisées à la description des résultats obtenus sans approfondir les facteurs sous-tendant ces résultats. La présente étude vise à analyser les facteurs influençant le fonctionnement des PI, en se basant sur le cas de l’intervention du projet ‘’Fertilizer Micro-Dosing and Indigenous Vegetable Production and Utilization (Micro-Veg)’’faisant la promotion des Légumes Feuilles Traditionnels (LFT) et leur mise à l’échelle au Bénin. Deux études de cas de PI ont été présentées suivant un cadre analytique combinant les méthodes des systèmes d’innovations et de l’analyse des fonctions. Ces études de cas concernent les villages de Wooré (commune de Parakou) et de Kouwentakouengou (commune de Boukombé) bénéficiaires des PI installées par le projet. Les données sont collectées lors des entretiens structurés, semi-structurés, des observations participantes, des témoignages, etc. Les données collectées sont relatives à chaque étape des processus de mise en oeuvre et concernent les acteurs (types d’acteurs, profil des acteurs, relations développées, rôles, attitudes, pratiques, perceptions etc), les différentes activités réalisées (entrepreneuriales, apprentissage, diffusion des innovations, investissements marchés développés, mobilisation des ressources humaines, financières matériels, lobbying des groupes d’intérêts), les difficultés rencontrées et approches de solutions. La méthode d’analyse est essentiellement qualitative. Les résultats ont montré que l’existence de marchés et la proximité des acteurs ont facilité la mise en oeuvre des PI. Par contre, la faible diversité des acteurs dans les PI, l’absence du facilitateur et la faible capacité des membres à apporter les solutions aux problèmes identifiés ont limité leur fonctionnement. Aussi, il est recommandé pour la mise à échelle des innovations que les initiatives des PI prennent en compte ces facteurs pour assurer l’efficacité de sa mise en oeuvre.
Do Post-Starburst Galaxies Host Compact Molecular Gas Reservoirs?

description: We analysed the high-resolution (up to $\sim$0.2") ALMA CO (2-1) and 1.3 mm dust continuum data of eight gas-rich post-starburst galaxies (PSBs) in the local Universe, six of which had been studied by Smercina et al. (2022). In contrast to this study reporting the detections of extraordinarily compact (i.e., unresolved) reservoirs of molecular gas in the six PSBs, our visibility-plane analysis resolves the CO (2-1) emission in all eight PSBs with effective radii ($R_\mathrm{e,CO}$) of $0.8_{-0.4}^{+0.9}$ kpc, typically consisting of gaseous components at both circumnuclear and extended disc scales. With this new analysis, we find that the CO sizes of gas-rich PSBs are compact with respect to their stellar sizes (median ratio $=0.43_{-0.21}^{+0.27}$), but comparable to the sizes of the gas discs seen in local luminous infrared galaxies (LIRGs) and early-type galaxies. We also find that the CO-to-stellar size ratio of gas-rich PSBs is potentially correlated with the gas depletion time scale, placing them as transitional objects between LIRGs and early-type galaxies from an evolutionary perspective. Finally, the star formation efficiency of the observed PSBs appear consistent with those of star-forming galaxies on the Kennicutt-Schmidt relation, showing no sign of suppressed star formation from turbulent heating.

description: We study the quantum phase transition mechanisms that arise in the Interacting Boson Model. We show that the second-order nature of the phase transition from U(5) to O(6) may be attributed to quantum integrability, whereas all the first-order phase transitions of the model are due to level repulsion with one singular point of level crossing. We propose a model Hamiltonian with a true first-order phase transition for finite systems due to level crossings.

description: The emergence of quantum sensor networks has presented opportunities for enhancing complex sensing tasks, while simultaneously introducing significant challenges in designing and analyzing quantum sensing protocols due to the intricate nature of entanglement and physical processes. Supervised learning assisted by an entangled sensor network (SLAEN) [Phys. Rev. X 9, 041023 (2019)] represents a promising paradigm for automating sensor-network design through variational quantum machine learning. However, the original SLAEN, constrained by the Gaussian nature of quantum circuits, is limited to learning linearly separable data. Leveraging the universal quantum control available in cavity-QED experiments, we propose a generalized SLAEN capable of handling nonlinear data classification tasks. We establish a theoretical framework for physical-layer data classification to underpin our approach. Through training quantum probes and measurements, we uncover a threshold phenomenon in classification error across various tasks -- when the energy of probes exceeds a certain threshold, the error drastically diminishes to zero, providing a significant improvement over the Gaussian SLAEN. Despite the non-Gaussian nature of the problem, we offer analytical insights into determining the threshold and residual error in the presence of noise. Our findings carry implications for radio-frequency photonic sensors and microwave dark matter haloscopes.

description: tau -> (3 pions) nu_tau decays are analysed within the framework of the resonance effective theory of QCD. We work out the relevant Lagrangian that describes the axial-vector current hadronization contributing to these processes, in particular the local a_1(1260)-rho(770)-Goldstone interactions. The new coupling constants are constrained by imposing the asymptotic behaviour of the corresponding spectral function within QCD. Hence we compare the theoretical framework with the experimental data, obtaining a good quality fit from the ALEPH spectral function and branching ratio. We also get values for the mass and on-shell width of the a_1(1260) resonance. In this way we are able to provide the structure functions that have been measured by OPAL and CLEO-II and we find an excellent agreement.

description: Various complementary split ring resonators (CSRRs) are used as defected ground structures (DGSs) in the bandpass filter (BPF) design for different communication applications. In this paper, a hybrid CSRR has been introduced as a DGS in the ground plane of a dual-mode microstrip BPF to produce a new compact filter with dual band response. The proposed CSRR structure is essentially based on the conventional square double ring one, but with the inner ring made in the form Minkowski-like pre-fractal curve. Simulation and performance evaluation of the proposed filter have been carried out using a method of moment based EM simulator; the IE3D. Simulation results show that the resulting filter offers a dual passband response. The higher passband is attributed to the dual mode microstrip ring structure, while the lower passband is as a result of the embedded CSRR DGS structure, which implies an extra filter miniaturization. Results also show that the position of the lower passband could be varied, to certain extent, without affecting the position of the higher passband. This can be performed by the application of higher fractal iteration level to the inner split ring and/or dimension scaling of the whole CSRR structure. This feature makes the proposed filter suitable as a candidate for use in a wide variety of communication systems incorporating dual band operation.

description: The formation of bubbles in nucleic acids (NAs) are fundamental in many biological processes such as DNA replication, recombination, telomeres formation, nucleotide excision repair, as well as RNA transcription and splicing. These precesses are carried out by assembled complexes with enzymes that separate selected regions of NAs. Within the frame of a nonlinear dynamics approach we model the structure of the DNA duplex by a nonlinear network of coupled oscillators. We show that in fact from certain local structural distortions there originate oscillating localized patterns, that is radial and torsional breathers, which are associated with localized H-bond deformations, being reminiscent of the replication bubble. We further study the temperature dependence of these oscillating bubbles. To this aim the underlying nonlinear oscillator network of the DNA duplex is brought in contact with a heat bath using the Nos$\rm{\acute{e}}$-Hoover-method. Special attention is paid to the stability of the oscillating bubbles under the imposed thermal perturbations. It is demonstrated that the radial and torsional breathers, sustain the impact of thermal perturbations even at temperatures as high as room temperature. Generally, for nonzero temperature the H-bond breathers move coherently along the double chain whereas at T=0 standing radial and torsional breathers result.

Here we report on our lattice QCD calculation of the hadronic vacuum polarisation contribution $a_μ^{\rm hvp}$, based on gauge ensembles with $N_f=2+1$ flavours of O($a$) improved Wilson quarks. We address the conceptual and numerical challenges that one encounters along the way to a sub-percent determination of the hadronic vacuum polarisation contribution. The current status of lattice calculations of $a_μ^{\rm hvp}$ is presented by performing a detailed comparison with the results from other groups.

The atomic contacts and wires are fabricated with a Scanning Tunneling Microscope. The set of transmission probabilities of the conduction channels is obtained from the analysis of the $I(V)$ characteristic curve which is highly non-linear due to multiple Andreev reflections. In agreement with theoretical calculations we find that there is only one channel which is almost completely open.

Designing an educational program for at-risk youth in transition from elementary to secondary school : comparing the traditional problem-solving approach to the design thinking approach
Creators: name: Kernohan, Kris
Publisher: name: The University of British Columbia
Year: 2012

description: Youth at-risk are challenged by life circumstances which can have long-term implications. When students move from elementary to secondary school, they encounter social, emotional, and academic challenges in the transition. However, because the factors which define at-risk students are similar to those accentuated by the transition process, the challenges faced by at-risk students are exacerbated, which further impacts their chance of future success. In order to better support students at-risk in transition to secondary school, a program which meets the unique needs of this group should be designed. A review of several definitions and the characteristics of at-risk youth, as well as current literature regarding the challenges presented by the transition to secondary school, is undertaken. Two different approaches to programmatic design for schools are defined and examined—the traditional problem-solving method, and the design thinking method. Each method is then used in a thought experiment in which worked examples of each method are presented. The two approaches are then compared, and the suitability of (1) the decision making processes and (2) the resulting types of programmatic structures is examined in relation to general educational needs and those specific to youth at-risk in transition to secondary school.. A guide for future practice in these domains is offered.

description: We use data from the Magellanic Edges Survey (MagES) in combination with Gaia EDR3 to study the extreme southern outskirts of the Small Magellanic Cloud (SMC), focussing on a field at the eastern end of a long arm-like structure which wraps around the southern periphery of the Large Magellanic Cloud (LMC). Unlike the remainder of this structure, which is thought to be comprised of perturbed LMC disk material, the aggregate properties of the field indicate a clear connection with the SMC. We find evidence for two stellar populations in the field: one having properties consistent with the outskirts of the main SMC body, and the other significantly perturbed. The perturbed population is on average ~0.2 dex more metal-rich, and is located ~7 kpc in front of the dominant population with a total space velocity relative to the SMC centre of ~230 km/s broadly in the direction of the LMC. We speculate on possible origins for this perturbed population, the most plausible of which is that it comprises debris from the inner SMC that has been recently tidally stripped by interactions with the LMC.

description: This study identifies and analyses the factors that influence the export performance of Indian garments manufacturing firms. The data come from a sample of seventy-four firms located in Okhla. The results show that intensity of adoption of Information Technology (IT) was the most significant variable that influenced the export performance of firms. The other variables that played an important role in augmenting the export intensity were quality of raw material and the wage rate. The results show that Managing Directors of export- oriented firms assigned more importance to flexibility in product designs. The study suggests that a higher degree of adoption of IT by Indian firms is crucial to remain internationally competitive. The use of advanced IT tools will be even more relevant once the WTO recommendations are in place.

description: With growing awareness of the dangers of an irreversible loss of plant genetic resources for food and agriculture (PGRFA), there has been a major effort devoted to collecting and conserving plant genetic resources. The objective of this study is to assess the level of investments in PGRFA conservation in different countries and their efficiency. Few studies of the costs and efficiency of genebanks and other methods of conservation exist so far. This study finds that the order of magnitude of domestic expenditures on the conservation of PGRFA by 37 countries amounts to approximately US $ 475 million for the year 1995. The efficiency of PGRFA conservation varies widely between countries. While a more comprehensive and thorough efficiency analysis of the countries’ conservation efforts is called for, the approach taken here does draw attention to practical solutions to the ongoing political discussions on the sharing of benefits and costs of PGRFA conservation and utilisation.

description: This paper presents a novel approach to processing multimodal data for dynamic emotion recognition, named as the Multimodal Masked Autoencoder for Dynamic Emotion Recognition (MultiMAE-DER). The MultiMAE-DER leverages the closely correlated representation information within spatiotemporal sequences across visual and audio modalities. By utilizing a pre-trained masked autoencoder model, the MultiMAEDER is accomplished through simple, straightforward finetuning. The performance of the MultiMAE-DER is enhanced by optimizing six fusion strategies for multimodal input sequences. These strategies address dynamic feature correlations within cross-domain data across spatial, temporal, and spatiotemporal sequences. In comparison to state-of-the-art multimodal supervised learning models for dynamic emotion recognition, MultiMAE-DER enhances the weighted average recall (WAR) by 4.41% on the RAVDESS dataset and by 2.06% on the CREMAD. Furthermore, when compared with the state-of-the-art model of multimodal self-supervised learning, MultiMAE-DER achieves a 1.86% higher WAR on the IEMOCAP dataset.

Newton-Cartan $ D 0$ branes from $ D1 $ branes and integrability

description: We explore analytic integrability criteria for $ D1 $ branes probing 4D relativistic background with a null isometry direction. We use both the Kovacic's algorithm of classical (non)integrability as well as the standard formulation of Lax connections to show the analytic integrability of the associated dynamical configuration. We further use the notion of double null reduction and obtain the world-volume action corresponding to a torsional Newton-Cartan (TNC) $ D0 $ brane probing a 3D torsional Newton-Cartan geometry. Moreover, following Kovacic's method, we show the classical integrability of the TNC $ D0 $ brane configuration thus obtained. Finally, considering a trivial field redefinition for the $ D1 $ brane world-volume fields, we show the equivalence between two configurations in the presence of vanishing NS fluxes.

description: The availability of telecommunications services is a necessary, though insufficient prerequisite for economic growth. In combination with transport, education, functioning financial markets, electricity, etc., telecommunications serve as an infrastructure required for any development exceeding that of a subsistence economy. The paper is showing the following relations between telecommunications and economic development: At present the telecommunications services with the highest growth potential and high economic importance are mobile radio services, international telephone traffic, and Internet applications. Investments in the telecommunications infrastructure are a major driving force for economic growth and generate additional GDP between US$ 250 and 500 bn through multiplier effects. Welfare effects for users of telecommunications services may reach a volume of US$ 900 bn per year. Effective use of telecommunications and information technology in companies has a considerable cost-saving potential and is of increasing significance with regard to the international competitiveness.

description: In this paper, a printed monopole antenna with reduced ground plane has been presented as a candidate for use in ultra-wideband applications. The monopole antenna structure is a nearly square shaped with m-slot embedded in it. A 50­ microstrip line is used to feed the proposed antenna. The proposed antenna has been supposed to be etched using a substrate with relative permittivity of 4.6 and thickness of 1.6 mm. Modeling and performance evaluation of the proposed antenna have been carried out using a method of moments based EM simulator, IE3D. Results show that the proposed antenna has a compact size of 20mm * 25 mm. The resulting antenna has been found to possess an impedance bandwidth, for voltage standing-
wave ratio less than 2, covering the required impedance bandwidth for UWB applications with 5/6 GHz band notch characteristics. Simulation results show that the lower frequency is primarily determined by the monopole radiating element perimeter, while the slot has an effective role to
allocate the position of the band notch. A parametric study has been conducted to provide more understanding of the effects of antenna parameters on its performance. Besides the reasonable performance, the simple structure of the proposed antenna will make it an attractive choice for the antenna designers.

description: In this paper we analyze the effectiveness of eco-labels in reducing the supply of eco-unfriendly products. We focus on the situation where a labeled product is viewed by consumers as a private good and develop a theoretical model to pin down the interaction between consumers' willingness to pay a higher price for a labeled product and producers' incentive to produce them. Based on the model results, we conclude that labeling is an effective device in solving the problem of asymmetric information on the part of consumers and does provide a market-based solution to the problem of eco-unfriendly methods of production. In particular, we focus on the incentive problems that producers face in the event of imperfect and costly monitoring of labels and conclude that (i) absent increased enforcement, there is a tendency for eco-labeling schemes to increase the number of products with false labels; (ii) there is a Kuznet's U-curve relationship between the supply of eco-friendly products and national income in the sense that it pays domestic governments to increase monitoring intensity of labeled products only after income crosses a threshold level and (iii) technology transfer from the developed to the developing countries that enhances the cost effectiveness of eco-friendly producers reduces the incentive for producers to use false labels. There is, however, the danger that labeling programs, especially the ones including production and process standards, will be misused as non-tariff trade barriers towards exports from developing countries. In order to avoid this, governments have to ensure active participation in the development of internationally accepted standards. Furthermore, there must be increased transparency on the existence of eco-labeling programs.

The Impact of Taxation in the Tourism Industry: Dynamic Approach

Year: 2021
Subjects: Economics

description: Tourism is becoming one of the essential pillars of any economy. Therefore, the best way to grow and upgrade this industry is to position the best tax rate that encourages tourism development. The Government should adjust the economies' tax system based on developing their tourism industry to improve this area's investment. Therefore, this study's main objective is to investigate the effect of the tax rate on the tourism industry in selected countries using the dynamic panel modeling (SGMM) method in the range of 2011 to 2016. The results indicate that the position of a robust tax system will harm the tourism industry. The high tax rate will hurt competition, and a major disaster will be toward competition and revenues. So, the hypothesis of this research indicates the negative impact of the tax rate on tourism revenues is accepted. Other variables such as per capita income and trade openness have a positive effect on tourism revenues.

description: We view conformal surfaces in the 4--sphere as quaternionic holomorphic curves in quaternionic projective space. By constructing enveloping and osculating curves, we obtain new holomorphic curves in quaternionic projective space and thus new conformal surfaces. Applying these constructions to Willmore surfaces, we show that the osculating and enveloping curves of Willmore spheres remain Willmore.

The recent star formation history of NGC 628 on resolved scales

description: Star formation histories (SFHs) are integral to our understanding of galaxy evolution. We can study recent SFHs by comparing the star formation rate (SFR) calculated using different tracers, as each probes a different timescale. We aim to calibrate a proxy for the present-day rate of change in SFR, dSFR/dt, which does not require full spectral energy distribution (SED) modeling and depends on as few observables as possible, to guarantee its broad applicability. To achieve this, we create a set of models in CIGALE and define an SFR change diagnostic as the ratio of the SFR averaged over the past 5 and 200 Myr, /, probed by the H$α$-FUV colour. We apply / to the nearby spiral NGC 628 and find that its star formation activity has overall been declining in the recent past, with the spiral arms, however, maintaining a higher level of activity. The impact of the spiral arm structure is observed to be stronger on / than on the star formation efficiency (SFE$_\text{H$_2$}$). In addition, increasing disk pressure tends to increase recent star formation, and consequently /. We conclude that / is sensitive to the molecular gas content, spiral arm structure, and disk pressure. The / indicator is general and can be used to reconstruct the recent SFH of any star-forming galaxy for which H$α$, FUV, and either mid- or far-IR photometry is available, without the need of detailed modeling.

description: The spin-crossover in organometallic molecules constitutes one of the most promising routes towards the realization of molecular spintronic devices. In this article, we explore the hybridization-induced spin-crossover in metal-organic complexes. We propose a minimal many-body model that captures the essence of the spin-state switching in a generic parameter space, thus providing insight into the underlying physics. Combining the model with density functional theory (DFT), we then study the spin-crossover in isomeric structures of Ni-porphyrin (Ni-TPP). We show that metal-ligand charge transfer plays a crucial role in the determination of the spin-state in Ni-TPP. Finally, we propose a spin-crossover mechanism based on mechanical strain, which does not require a switch between isomeric structures.

description: Higher harmonics normally accompany the performance of bandpass filters; and the miniaturized microstrip dual mode bandpass filters are not an exception. The use of the conventional open stub resonator to reduce such harmonics is not a practical solution since it has a length of a quarter the guided wavelength at the harmonic frequency. This will make the miniaturized filter larger. In this paper, the use of a fractal based open stub, with high space-filling property, has been investigated as a more practical solution of the 2nd harmonic reduction of the miniaturized dual mode bandpass filters. The proposed stub has the Peano fractal shape geometry which is characterized by its high space-filling property. The Peano based stub has been applied
to many miniaturized filter reported in the literature. Modeling and performance evaluation of the presented filters have been carried out using a full-wave electromagnetic EM simulator, from Sonnet Software Inc. Simulation results show that the introduction of the proposed stub maintains the physical size of the filter under test and improves the filter performance by reducing the harmonics to satisfactory levels. This might presents a solution for second harmonic reduction of a wide variety of miniaturized dual mode bandpass filters with different miniaturization levels.
