Subjects: subject: 150304 Entrepreneurship
subject: FOS: Economics and business

description: Evidences from several sources including the Global Entrepreneurship Monitor (GEM) suggest that entrepreneurial intent is high amongst young Chinese graduates, but support mechanisms are either lacking or misunderstood by those entrepreneurs aiming to start their own business. The aim of this work was to suggest recommendations to narrow this gap. To this end, a comparison was undertaken to examine what government measures exist and are effective in a well-developed, highly ranked entrepreneurial economy such as in the UK as compared to that of China and what could be recommended to boost entrepreneurial culture and output, boosting economic activity. A number of areas have been considered for comparison including financial support such as loans and grants as well as red tape and incentives which may directly or indirectly affect the ease of starting a business (

description: A process of the decay of the anomalously low lying nuclear isomer $^{229m}$Th$(3/2^+,8.28 \pm 0.17$ eV) in the Thorium anion (Th$^-$) via the internal conversion (IC) channel is studied. We show that the half life of the nuclear isomer in the $6d_{3/2}^37s_{1/2}^2$ ground state and in the $6d_{3/2}^2 7s_{1/2}^2 7p_{1/2}^1$ excited state of Th$^-$ is $\approx1.5$ and $\approx1.1$ times bigger than in the $6d_{3/2}^2 7s_{1/2}^2$ ground state of the Th atom. The IC probabilities in the anion decreases despite the decay via the additional $6d_{3/2}$ or $7p_{1/2}$ electrons. This counterintuitive result is a consequence: a) of a decrease in the amplitudes of the $6d_{3/2}$ and $7s_{1/2}$ wave functions near the nucleus due to an increase in their diffuseness of upon the addition of extra electron, b) of mutual compensation in the IC probability due to a kinematic factor, which depends on the energy of the conversion electron in the continuum as $E_c^{-1/2}$, and the $E_c^{1/4}$ growth of the amplitudes of the electron wave functions.

title: Understanding Ion Rejection Mechanism of Freeze Desalination by Molecular Dynamics Simulation
Creators: name: Jannat, Mahbuba
Publisher: name: Utah State University
Year: 2024

description: This study explores a method called freeze desalination, which uses the natural process of ice formation to remove salt from water at lower than freezing temperature of water, which is 235K (Freezing temperature of this water model is 249K), making it safe for potable water. Unlike traditional methods, freeze desalination can be more efficient and environmentally friendly, but how it rejects salt at the molecular level is not very clear to understand. Using molecular dynamics simulation, this research aims to uncover the details of this process. We focused on understanding how water molecules interact with salt ions during freezing. Our findings showed that over 90% of salt ions can be successfully removed from the water under optimal conditions, with certain temperatures and settings leading to the best results. Specifically, we found that sodium ions are removed more effectively than chloride ions. This difference is due to how sodium and chloride ions interact with the surrounding water molecules, which was measure by calculation of free energies. These insights are crucial for improving the technique and making it a viable option for purifying water in different settings. Overall, this work provides a clearer picture of how freeze desalination works at a microscopic level, offering guidance on how to optimize this process for better performance. This could have significant implications for water purification technology, potentially leading to more widespread use of freeze desalination in the future.

description: Measurement-device-independent quantum key distribution (MDI-QKD) removes all detector side channels and enables secure QKD with an untrusted relay. It is suitable for building a star-type quantum access network, where the complicated and expensive measurement devices are placed in the central untrusted relay and each user requires only a low-cost transmitter, such as an integrated photonic chip. Here, we experimentally demonstrate a 1.25 GHz silicon photonic chip-based MDI-QKD system using polarization encoding. The photonic chip transmitters integrate the necessary encoding components for a standard QKD source. We implement random modulations of polarization states and decoy intensities, and demonstrate a finite-key secret rate of 31 bps over 36 dB channel loss (or 180 km standard fiber). This key rate is higher than state-of-the-art MDI-QKD experiments. The results show that silicon photonic chip-based MDI-QKD, benefiting from miniaturization, low-cost manufacture and compatibility with CMOS microelectronics, is a promising solution for future quantum secure networks.

description: Transbothriurus (Bothriuridae)
 In a revision of the genus Bothriurus Peters 1861, Mello­Leitão (1934) recognized a species group, "Grupo B ­ Bothriurus dorbignyi ", containing the old name Scorpio D’Orbignyi Guérin­Méneville 1843 and Bothriurus elegans Mello­Leitão 1931. This two­species assemblage was given a formal subgeneric status by Mello­Leitão (1945), who gave the name Bothriurus (Transbothriurus) to the former "Grupo B". But he did not designate a type species, so the genus­group name did not become available (Art. 13.3). Bücherl (1959) proposed that B. elegans was a junior synonym of B. dorbignyi, reducing the 'subgenus' to a single species. This simple procedure of 'elimination' does not constitute a valid designation of type species (Art. 69.4), so the name Transbothriurus still remained unavailable. Bücherl et al. (1963) continued to recognize the monotypic 'subgenus' Transbothriurus and to assign authorship to Mello­Leitão (1945). Finally, Maury & San Martin (1973) discovered that an available name for this assemblage already existed: the long forgotten but valid genus name Timogenes Simon 1880. They then placed Transbothriurus in the 'synonymy' of Timogenes, without ever acknowledging that the former was still unavailable. Lowe & Fet (2000) noticed the status of Transbothriurus, and then proposed Scorpio dorbignyi as the type species, in order to make it available. They (p. 13, 40) denoted their nomenclatural act as "nomen novum", as if it were a replacement name because of homonymy, while the right notation should have been "gen. nov." (they just wanted to make the name available). Lowe & Fet (2000) never used Transbothriurus as valid, since it remained as junior synonym of Timogenes, in accordance with the preceding taxonomic concepts. Thus, Transbothriurus was not thereby made available (Art. 11.6.3).

description: The idea of the Balance of Nature (BON-idea), which implies a predetermined order and stability guaranteed by a God’s will or nature itself, is much older than the science of ecology and had a remarkable influence on it. It seems that the history of the BON-idea might be used for highlighting Nature of Science (NOS). Our study concerns whether it is actually feasible to draw on the BON-idea history in order to design historical narratives that could effectively support students to reach a better understanding of general NOS aspects. In this paper, we focus on which general NOS aspects could be highlighted by the BON-idea history and how. So, we argue that the BON-idea history can offer resources for the design of narratives that outline scientific knowledge as (i) influenced by socio-cultural contexts, (ii) mediated by creativity, and (iii) subject to change.

For a beam with a non zero angle of incidence the transmitted electrons will split into two spin polarization components propagating at different angles. We analyze the refraction at such an interface and outline the basic schemes for filtration and control of the electron spin.

description: The Cherenkov Imaging Telescope Integrated Read Out Chip (CITIROC) is a 32-channel fully analogue front-end ASIC dedicated to the read-out of silicon photo-multiplier (SiPM) sensors that can be used in a variety of experiments with different applications: nuclear physics, medical imaging, astrophysics, etc. It has been adopted as front-end for the focal plane detectors of the ASTRI-Horn Cherenkov telescope and, in this context, it was modified implementing the peak detector reading mode to satisfy the instrument requirements. For each channel, two parallel AC coupled voltage preamplifiers, one for the high gain and one for the low gain, ensure the read-out of the charge from 160 fC to 320 pC (i.e. from 1 to 2000 photo-electrons with SiPM gain = 10$^{6}$, with a photo-electron to noise ratio of 10). The signal in each of the two preamplifier chains is shaped and the maximum value is captured by activating the peak detector for an adjustable time interval. In this work, we illustrate the peak detector operation mode and, in particular, how this can be used to calibrate the SiPM gain without the need of external light sources. To demonstrate the validity of the method, we also present and discuss some laboratory measurements.

 Type species. Quichuamyia aplanatantennae sp. nov.
 Diagnosis. This genus can be distinguished from other Stratiomyidae by the distinct apomorphy of antennae having eight laterally compressed flagellomeres that are taller than long. The genus can also be recognized by a unique combination of characters: 1) the ocellar triangle is raised above the vertex on a tubercle; 2) the ventral edge of lower frons appears bilobed in the female; and 3) the scutellum has a pair of long, straight spines. Setal pattern of thorax and abdomen is distinct, but, coupled with wing coloration and posterior of head coloration, bears a strong resemblance to Artemita convexa (Walker) (Pachygastrinae).
 Description: Ocellar triangle raised above vertex on a tubercle 1.5–2.0 X height of single ocellus. Antennae laterally compressed, width 0.25 or less the height of flagellomeres; flagellomeres twice as tall as long; eighth flagellomere nearly as long as sixth and seventh combined. Lower frons dark brown to black, with whitish and brown semi­erect setae. Thorax integument black, dull, with silver or gold patterns of appressed pilosity on dorsum and lateral margins; scutellum black with appressed black and gold pilosity, spines yellow, straight, situated close together, longer than scutellum, projecting posteriorly, slightly laterally divergent. Femur yellow, brown cross­band in apical 0.33. Tibia dark brown to black. Anterior tarsus entirely dark brown to black, laterally compressed with a ventral row of thickened setae, giving the tarsus a saw­like appearance. Basal two tarsomeres of meso­ and metatarsus yellow, apical three tarsomeres brown; abdomen black, dull, with contrasting setal pattern. Male: eyes holoptic, bare, adjoined in central 0.33 of head, smaller ommatidia in ventral 0.33 of eye. Ocellar triangle dark brown, raised on tubercle. Lower frons dark brown, with silver appressed and semi­erect setae; outer lateral margins of frons with fine line of silver tomentum. Female: upper frons and post­ocular area orange­red, thick short black setae on upper frons, silver­white tomentum along outer lateral margin of upper and lower frons; ventral margin with central furrow and swollen lateral areas, so lower frons appears bilobed; eyes dichoptic, bare, ommatidia of even size throughout.
 Etymology. The genus is named for the native inhabitants of the area in which the taxon was first discovered, and the location of the type species, the Quichua people of the Province of Napo in Ecuador, South America. (Latin myia = fly).

Here we analyze the work of a team of trainees who designed a session on programming with Scratch, in terms of the potential of the lesson designed for the use of Scratch and student autonomy, and the professional knowledge mobilised. The analysis of this case highlights possibilities and limitations of such a training.

description: Large databases that can be used in the search for new materials with specific properties remain an elusive goal in materials science. The search problem is complicated by the fact that the optimal material for a given application is usually a compromise between a number of materials properties and the price. In this letter we present a database consisting of the lattice parameters, bulk moduli, and heats of formation for over 64,000 ordered metallic alloys, which has been established by direct first-principles density-functional-theory calculations. Furthermore, we use a concept from economic theory, the Pareto-optimal set, to determine optimal alloy solutions for the compromise between low compressibility, high stability and price.

description: This paper describes the measurement of entrepreneurial outcomes from a four day residential Enterprise School for Ph. D. and postdoctoral researchers from a mix of subject areas held in North West England. We determine the effectiveness of the programme in terms of encouraging a range of entrepreneurial behaviours from increased confidence to start a business to the actual creation of a business, and also intermediate outcomes such as using their new skills when returning to the workplace. Using a questionnaire at the end of the course and then eight months later, we have tried to fit the outcomes to the Rugby Team Framework as a model to measure the impact of the school in terms of what elements of the course they had incorporated in their workplace. We found that most students after returning still said they were more likely to start a business, a small number had actually started a business but interestingly we found that many were using the skills they learned now in the workplace, for example, opportunity spotting. These intermediate outcomes are often neglected by other studies but could prove valuable for employers and from those employees with them leading to higher employability and faster promotions.
LEP Data and the Stability of the Potential Confront the mSUGRA Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The requirement that the supersymmetric scalar potential be stable in the minimal supergravity (mSUGRA) model imposes an upper bound on the universal gaugino mass $m_{1/2}$ as function of the common scalar mass $m_0$. Combining this with the experimental lower bound on $m_{1/2}$ from LEP data, we find a new lower bound on $m_0$, stronger than the one that comes from experimental data alone. If the corresponding upper and lower limits on the superparticle masses, presented in this letter, are found to be violated at Tevatron Run II or at the LHC, it would imply that we are living on a false vacuum. Special attention has been paid in estimating the uncertainties in these predictions due to the choice of the renormalization scale. The implications of our limits for the constraints obtained by indirect methods(SUSY dark matter, g - 2 of the muon, $ b \to s γ$....) are briefly discussed.

description: Millions of devices are going to participate in 5G producing a huge space for security threats. The 5G specification goals require rigid and robust security protocol against such threats. Quantum cryptography is a recently emerged term in which we test the robustness of security protocols against Quantum computers. Therefore, in this paper, we propose a security protocol called Quantum Key GRID for Authentication and Key Agreement (QKG-AKA) scheme for the dynamic security association. This scheme is efficiently deployed in Long Term Evolution (LTE) architecture without any significant modifications in the underlying base system. The proposed QKG-AKA mechanism is analyzed for robustness and proven safe against quantum computers. The simulation results and performance analysis show drastic improvement regarding security and key management over existing schemes.

description: We present a high order perturbation approach to quantitatively calculate spectral densities in three distinct steps starting from the model Hamiltonian and the observables of interest. The approach is based on the perturbative continuous unitary transformation introduced previously. It is conceived to work particularly well in models allowing a clear identification of the elementary excitations above the ground state. These are then viewed as quasi-particles above the vacuum. The article focuses on the technical aspects and includes a discussion of series extrapolation schemes. The strength of the method is demonstrated for S=1/2 two-leg Heisenberg ladders, for which results are presented.

description: We use {\it ab initio} molecular dynamics simulations to study a sample of liquid silica containing 3.84 wt.% H$_2$O.We find that, for temperatures of 3000 K and 3500 K,water is almost exclusively dissolved as hydroxyl groups, the silica network is partially broken and static and dynamical properties of the silica network change considerably upon the addition of water.Water molecules or free O-H groups occur only at the highest temperature but are not stable and disintegrate rapidly.Structural properties of this system are compared to those of pure silica and sodium tetrasilicate melts at equivalent temperatures. These comparisons confirm the picture of a partially broken tetrahedral network in the hydrous liquid and suggest that the structure of the matrix is as much changed by the addition of water than it is by the addition of the same amount (in mole %) of sodium oxide. On larger length scales, correlations are qualitatively similar but seem to be more pronounced in the hydrous silica liquid. Finally, we study the diffusion mechanisms of the hydrogen atoms in the melt. It turns out that HOSi$_2$ triclusters and SiO dangling bonds play a decisive role as intermediate states for the hydrogen diffusion.

description: Dynamic Bayesian networks (DBNs) offer an elegant way to integrate various aspects of language in one model. Many existing algorithms developed for learning and inference in DBNs are applicable to probabilistic language modeling. To demonstrate the potential of DBNs for natural language processing, we employ a DBN in an information extraction task. We show how to assemble wealth of emerging linguistic instruments for shallow parsing, syntactic and semantic tagging, morphological decomposition, named entity recognition etc. in order to incrementally build a robust information extraction system. Our method outperforms previously published results on an established benchmark domain.

The study reports similar findings as other studies such as need to be prepared with a clear and transparent video disclosing the content and uniqueness of projects, appropriate modest funding target and many investors being geographically close to the artists and their existing network. Although investors were not strictly early adopters as might be found with hi-tech investors, they still want something unique and personal as a reward. However, it is found that they are worried by the amount of time and resources needed to promote the project and supply rewards.

description: A magnetically trapped 87Rb Bose-Einstein condensate is used as a sensitive probe of short-range electrical forces. In particular, the electric polarization of, and the subsequent electric field generated by, 87Rb adsorbates on conducting and insulating surfaces is measured by characterizing perturbations to the magnetic trapping potential using high-Q condensate excitations. The nature of the alterations to the electrical properties of Rb adsorbates is studied on titanium (metal) and silicon (semiconductor) surfaces, which exhibit nearly identical properties, and on glass (insulator), which displays a smaller transitory electrical effect. The limits of this technique in detecting electrical fields and ramifications for measurements of short-range forces near surfaces are discussed.

R-mode oscillations of rapidly rotating barotropic stars in general relativity: Analysis by the relativistic Cowling approximation

description: We develop a numerical scheme for obtaining the $r$-mode oscillations of rapidly rotating relativistic stars. In the present scheme, we neglect all metric perturbations and only take account of the dynamics of the fluid in the background spacetime of the unperturbed star (the relativistic Cowling approximation). We also assume the star is barotropic, i.e. neutrally stable against convection under the assumption of adiabatic oscillations. Our numerical scheme is based on the Yoshida-Eriguchi formulation for the analysis of the general relativistic f-mode oscillations in the Cowling approximation and a general relativistic generalization of the Karino-Yoshida-Yoshida-Eriguchi's numerical scheme for obtaining oscillations of rapidly rotating Newtonian stars. By this new numerical scheme, frequencies of the $r$-mode oscillations are obtained as functions of the ratio of the rotational energy to the absolute value of the gravitational energy $T/|W|$ along sequences of polytropic equilibrium stars whose ratio of the pressure to the total energy density at the center of the star and the polytropic index are kept constant. It is found that the dimensionless oscillation frequency $σ/Ω$ is a linearly decreasing function of $T/|W|$, where $σ$ and $Ω$ are the oscillation frequency and the angular velocity of the star measured in an inertial frame at spatial infinity. We also find that oscillation frequencies of the $r$-modes are highly dependent on the relativistic factor $M/R$ of the star as already found in previous studies in which the slow rotation approximation has been used. Here $M$ and $R$ denote the mass and radius of the star, respectively.

description: We formulate Lehmer's Problem about the Mahler measure of polynomials for general compact abelian groups, introducing a Lehmer constant for each such group. We show that all nontrivial connected compact groups have the same Lehmer constant, and conjecture the value of the Lehmer constant for finite cyclic groups. We also show that if a group has infinitely many connected components then its Lehmer constant vanishes.

description: This report is a continuation of the work that has been described in D 2.1 “Report on energy efficiency potentials in the transport sector”. These two deliverables provide key insights about the EU-28 transport sector and form the basis of the quantification of synergies among all sectors. This report is mainly focused on the quantified assessment of different energy efficiency scenarios for the EU-28 transport sector in 2050. Chapter 2 provides an overview of the methodology of analysis; followed by a detailed explanation of the methodology behind creating an EU 28 transport baseline and energy efficiency transport scenarios. This chapter also details the workings of the AAU’s scenario modeling tool TransportPLAN used for the analysis. In addition, it also describes the work done for creating different future energy efficiency scenarios including the calculations performed for alternative growth rates and modal shift rates. Finally, the results are presented in Chapter 3 and a short note on discussions and recommendations is provided in Chapter 4.

description: Using high-resolution SPH numerical simulations, we investigate the effects of gas on the inspiral and merger of a massive black hole binary. This study is motivated by both observational and theoretical work that indicate the presence of large amounts of gas in the central regions of merging galaxies. N-body simulations have shown that the coalescence of a massive black hole binary eventually stalls in a stellar background. However, our simulations suggest that the massive black hole binary will finally merge if it is embedded in a gaseous background. Here we present results in which the gas is assumed to be initially spherical with a relatively smooth distribution. In the early evolution of the binary, the separation dimishes due to the gravitational drag exerted by the background gas. In the later stages, when the binary dominates the gravitational potential in its vicinity, the medium responds by forming an ellipsoidal density enhancement whose axis lags behind the binary axis, and this offset produces a torque on the binary that causes continuing loss of angular momentum and is able to reduce the binary separation to distances where gravitational radiation is efficient. Assuming typical parameters from observations of Ultra Luminous Infrared Galaxies, we predict that a black hole binary will merge within $10^{7}$yrs; therefore these results imply that in a merger of gas-rich galaxies, any massive central black holes will coalescence soon after the galaxies merge. Our work thus supports scenarios of massive black hole evolution and growth where hierarchical merging plays an important role. The final coalescence of the black holes leads to gravitational radiation emission that would be detectable up to high redshift by LISA. We show that similar physical effects are important for the formation of close binary stars.

description: The bulk synchronous parallel (BSP) is a celebrated synchronization model for general-purpose parallel computing that has successfully been employed for distributed training of machine learning models. A prevalent shortcoming of the BSP is that it requires workers to wait for the straggler at every iteration. To ameliorate this shortcoming of classic BSP, we propose ELASTICBSP a model that aims to relax its strict synchronization requirement. The proposed model offers more flexibility and adaptability during the training phase, without sacrificing on the accuracy of the trained model. We also propose an efficient method that materializes the model, named ZIPLINE. The algorithm is tunable and can effectively balance the trade-off between quality of convergence and iteration throughput, in order to accommodate different environments or applications. A thorough experimental evaluation demonstrates that our proposed ELASTICBSP model converges faster and to a higher accuracy than the classic BSP. It also achieves comparable (if not higher) accuracy than the other sensible synchronization models.

title: Citizen Science Project on Urban Canids Provides Different Results From Camera Traps but Generates Interest and Revenue

description: As more people live in cities, wildlife increasingly encounters people. Coyotes (Canis latrans) and red foxes (Vulpes vulpes) are two carnivores that have easily adapted to urban environments causing them to come into conflict with people and their pets. Citizen science, where members of the community aid scientists in the collection of data, has emerged as a low-cost method of studying these species that can provide benefits to management agencies but may provide different results than traditional methods. We analyzed data collected by citizen scientists and data collected via motion-triggered camera traps to see how each relates to distance to roads, building density, median household income, and distance to water. We also investigated the potential benefits of advertising the citizen science project on social media. To evaluate differences between the two methods, we used data from a grid of 67 cameras across the city of Wichita, Kansas, USA, between March 2023 and February 2024 and data collected simultaneously from a website we created and advertised on social media where members of the public could report sightings of urban coyotes and foxes to determine canid distribution. The camera-trap models suggested that red fox occurrence was not related to any of our variables and coyote occurrence was only related negatively to building density. The citizen science models suggested that sightings of both species were more likely closer to roads, at intermediate building densities, and in high income neighborhoods. Additionally, coyotes and red foxes were both most likely to be detected by people during crepuscular periods but most likely to be detected by cameras at night. We also found that in addition to increasing the reports of sightings from the public, the advertisements generated six times as much revenue for the wildlife agency than was spent. Our study suggests that citizen science data differs from camera-trap data by human activity patterns and distribution, but citizen science projects can provide other benefits such as generating revenue for management agencies.
