description: Total world demand for tuna has increased rapidly over the 1956-66 period. These increases in demand are due to rising populations and expanding per capita income in the principal tuna-consuming countries such as the United States, Japan and the E.E.C. countries. This paper attempts to discover the relationship between per capita tuna consumption, tuna prices and real per capita income for the nine leading tuna-consuming countries. On the basis of these relationships the world demand for tuna is projected to the year 1990. When projected increases in population and standard of living (i.e., per capita income) are accounted for over the next twenty years, it is estimated that tuna consumption will rise from 1,320,000metric tons in 1966 to approximately 5,000,000 metric tons in 1990 assuming the existence of 1966 prices throughout the projection period and available world supplies. If the maximum sustainable yield of tuna on a world basis is no more than 2,600,000 metric tons and additional increase in world production is likely from only the skipjack resource, it is very likely that cost and prices will rise and demand will be reduced. Assuming a world price elasticity of unity for tuna, it is estimated that by 1990, world demand and supply will be equal at an ex vessel price of over 38 cents per, pound and consumption of about 2,100,000 metric tons under existing technology of harvesting the tuna.resource. In this event, technological change through gear and biological research may bring about an expansion of the world tuna fishery and reduced prices. However, this research and development must be accompanied by a vigorous fishei7 management program to prevent the destruction of.the resource. Without thib fishery management program,.technological change can only bring long run negative returns to the world tunaconsuming and producing nations.

description: The relationship between genotype and phenotype plays a crucial role in determining the function and robustness of biological systems. Here the evolution progresses through the change in genotype, whereas the selection is based on the phenotype, and genotype-phenotype relation also evolves. Theory for such phenotypic evolution remains poorly-developed, in contrast to evolution under the fitness landscape determined by genotypes. Here we provide statistical-physics formulation of this problem by introducing replicas for genotype and phenotype. We apply it to an evolution model, in which phenotypes are given by spin configurations; genotypes are interaction matrix for spins to give the Hamiltonian, and the fitness depends only on the configuration of a subset of spins called target. We describe the interplay between the genetic variations and phenotypic variances by noise in this model by our new approach that extends the replica theory for spin-glasses to include spin-replica for phenotypes and coupling-replica for genotypes. Within this framework we obtain a phase diagram of the evolved phenotypes against the noise and selection pressure, where each phase is distinguished by the fitness and overlaps for genotypes and phenotypes. Among the phases, robust fitted phase, relevant to biological evolution, is achieved under the intermediate level of noise (temperature), where robustness to noise and to genetic mutation are correlated, as a result of replica symmetry. We also find a trade-off between maintaining a high fitness level of phenotype and acquiring a robust pattern of genes as well as the dependence of this trade-off on the ratio between the size of the functional (target) part to that of the remaining non-functional (non-target) one. The selection pressure needed to achieve high fitness increases with the fraction of target spins.

description: Digital privacy has become an essential component of information and communications technology (ICT) systems. There are many existing methods for digital privacy protection, including network security, cryptography, and access control. However, there is still a gap in the digital privacy protection levels available for users. This paper studies the digital privacy divide (DPD) problem in ICT systems. First, we introduce an online DPD study for understanding the DPD problem by collecting responses from 776 ICT users using crowdsourcing task assignments. Second, we propose a factor analysis-based statistical method for generating the DPD index from a set of observable DPD question variables. In particular, the DPD index provides one scaled measure for the DPD gap by exploring the dimensionality of the eight questions in the DPD survey. Third, we introduce a DPD proportional odds model for analyzing the relationship between the DPD status and the socio-demographic patterns of the users. Our results show that the DPD survey meets the internal consistency reliability with rigorous statistical measures, e.g., Cronbach's $α=0.92$. Furthermore, the DPD index is shown to capture the underlying communality of all DPD variables. Finally, the DPD proportional odds model indicates a strong statistical correlation between the DPD status and the age groups of the ICT users. For example, we find that young users (15-32 years) are generally more concerned about their digital privacy than senior ones (33 years and over).

description: We present first principles calculations of the magnetic moments and magnetic anisotropy energies of small Fe, Co and Ni clusters on top of a Ag(100) surface as well as the exchange-coupling energy between two single adatoms of Fe or Co on Ag(100). The calculations are performed fully relativistically using the embedding technique within the Korringa-Kohn-Rostoker method. The magnetic anisotropy and the exchange-coupling energies are calculated by means of the force theorem. In the case of adatoms and dimers of iron and cobalt we obtain enhanced spin moments and, especially, unusually large orbital moments, while for nickel our calculations predict a complete absence of magnetism. For larger clusters, the magnitudes of the local moments of the atoms in the center of the cluster are very close to those calculated for the corresponding monolayers. Similar to the orbital moments, the contributions of the individual atoms to the magnetic anisotropy energy strongly depend on the position, hence, on the local environment of a particular atom within a given cluster. We find strong ferromagnetic coupling between two neighboring Fe or Co atoms and a rapid, oscillatory decay of the exchange-coupling energy with increasing distance between these two adatoms.

description: In this paper we introduce an open-source software package written in C++ for efficiently finding solutions to quadratic programming problems with linear complementarity constraints. These problems arise in a wide range of applications in engineering and economics, and they are challenging to solve due to their structural violation of standard constraint qualifications, and highly nonconvex, nonsmooth feasible sets. This work extends a previously presented algorithm based on a sequential convex programming approach applied to a standard penalty reformulation. We examine the behavior of local convergence and introduce new algorithmic features. Competitive performance profiles are presented in comparison to state-of-the-art solvers and solution variants in both existing and new benchmarks.

description: In recent decades, several assistive technologies have been developed to improve the ability of blind and visually impaired (BVI) individuals to navigate independently and safely. At the same time, simultaneous localization and mapping (SLAM) techniques have become sufficiently robust and efficient to be adopted in developing these assistive technologies. We present the first systematic literature review of 54 recent studies on SLAM-based solutions for blind and visually impaired people, focusing on literature published from 2017 onward. This review explores various localization and mapping techniques employed in this context. We systematically identified and categorized diverse SLAM approaches and analyzed their localization and mapping techniques, sensor types, computing resources, and machine-learning methods. We discuss the advantages and limitations of these techniques for blind and visually impaired navigation. Moreover, we examine the major challenges described across studies, including practical challenges and considerations that affect usability and adoption. Our analysis also evaluates the effectiveness of these SLAM-based solutions in real-world scenarios and user satisfaction, providing insights into their practical impact on BVI mobility. The insights derived from this review identify critical gaps and opportunities for future research activities, particularly in addressing the challenges presented by dynamic and complex environments. We explain how SLAM technology offers the potential to improve the ability of visually impaired individuals to navigate effectively. Finally, we present future opportunities and challenges in this domain.

description: Deep learning has emerged as an effective solution for solving the task of object detection in images but at the cost of requiring large labeled datasets. To mitigate this cost, semi-supervised object detection methods, which consist in leveraging abundant unlabeled data, have been proposed and have already shown impressive results. However, most of these methods require linking a pseudo-label to a ground-truth object by thresholding. In previous works, this threshold value is usually determined empirically, which is time consuming, and only done for a single data distribution. When the domain, and thus the data distribution, changes, a new and costly parameter search is necessary. In this work, we introduce our method Adaptive Self-Training for Object Detection (ASTOD), which is a simple yet effective teacher-student method. ASTOD determines without cost a threshold value based directly on the ground value of the score histogram. To improve the quality of the teacher predictions, we also propose a novel pseudo-labeling procedure. We use different views of the unlabeled images during the pseudo-labeling step to reduce the number of missed predictions and thus obtain better candidate labels. Our teacher and our student are trained separately, and our method can be used in an iterative fashion by replacing the teacher by the student. On the MS-COCO dataset, our method consistently performs favorably against state-of-the-art methods that do not require a threshold parameter, and shows competitive results with methods that require a parameter sweep search. Additional experiments with respect to a supervised baseline on the DIOR dataset containing satellite images lead to similar conclusions, and prove that it is possible to adapt the score threshold automatically in self-training, regardless of the data distribution.

description: The origin of the arc-shaped Sh2-296 nebula is still unclear. Mainly due to its morphology, the nebula has been suggested to be a 0.5 Myr-old supernova remnant (SNR) that could be inducing star formation in the CMa OB1 association. We aim to show, for the first time, that the nebula is part of a large, shell-like structure, which we have designated the ``CMa shell'', enclosing a bubble created by successive supernova (SN) explosions. We identified three runaway stars, associated with bow-shock structures, in the direction of the CMa shell and we investigate the possibility that they have originated in the center of the shell. By analyzing images of the CMa OB1 association at several wavelengths, we clearly see that the Sh2-296 nebula is in fact part of a large structure, which can be approximated by a large (with a diameter of ~60 pc) elliptical shell. Using the recent Gaia-DR2 astrometric data, we trace back the path of the three runaway stars, in order to find their original position in the past, with relation to the CMa shell. We also revise the heating and ionization of the Sh2-296 nebula, by comparing the photon budget provided by the O stars in the region with results from radio observations. We find that the runaway stars have likely been ejected from a Trapezium-like progenitor cluster on three successive SN explosions having taken place ~6, ~2 and ~1 Myr ago. We also show that the few late-type O stars in the region cannot explain the ionization of the Sh~2-296 nebula and other mechanisms need to be at work. We argue that, though we now have evidence for several SNe events in the CMa OB1 association, the SNe probably played a minor role in triggering star formation in these clouds. In contrast, the CMa OB1 association, as it is now, likely testifies to the last stages of a star-forming region.

description: Abstract - This study analyzes the scientific literature published in Argentina between 1985 and 2019. It examines the characteristics and the temporal variation in the number of publications, the total number of author, the percentage of participation of Argentine researchrs, the species and region of study, as well as the researchtopics they address. The results show a tendency towards an increase in papers and studies of these birds, the tota number of authors, and the participation of researchers beloging to Argetine research centers during the period analyzed. The most studied penguin species was the Magellanic Penguin (Spheniscus
magellanicus), followed by the Southern Rockhopper Penguin (Eudyptes chrysocome) and the Gentoo Penguin
(Pygoscelis papua). The most addressed research topics were foraging and diet, followed by reproduction and
reproductive success, conservation and wildlife management, population dynamics and physiology and histology, which were carried out mainly in the Patagonian region and in the Malvinas Islands. The results help to
understand the past, present and future state of scientific literature, which will strengthen decision-making on
future research on penguins.

description: To attend to the Vedic rituals like honouring the dead (śrāddha) he settled in the new territory sixty families of citpāvan brāhmaṇ, ‘who were fair skinned, handsome and had beautiful eyes’. The place where they were settled, was at the feet of the Sahyādrī, and was named Cittapōlan (Cipluṇ). Then he brought ten brāhmaṇ families from Trihōtr from among the pañc gauḍ brāhmaṇ, and settled them at Pan̄cakrōśī and Kuśasthaḷ in Goa. These were families of bhārdvaj, kauśik, vats, kaunḍinya, kaśyap, vasiṣṭh, bhārgava, viśvamitr, gautam and atri gōtr, and were settled in Maṭhagrām (Margao), Kuśasthaḷ (Cortalim) and Kardalinagar (Kēḷśī = Quelossim). [SHKG, 123; SHKD, 303] The fourth chapter of SKH named Vividhbrāhmaṇōtpati, elaborates on the settlement of these daśgōtrī (of ten gōtr as above) brāhmaṇ.Of the total sixty six families, ten were of kauśik, vats and kaunḍinyagōtr; these were settled at Kuśasthaḷ and Kēḷśī.Six families each in Loṭli, Kuśasthaḷ, Varēṇya (Verna) and Maṭhagrām. Ten families in Cuḍāmani (Chorao) and eight in Dipāvati (Divar). Twelve in the centre of Goa (Bardez ?) and in its Paṁcakrōśi (Pedne ?). Though SHK does not say it explicitly, it is obvious that the sixty families of daśgōtrī brāhmaṇ brought from Trihōtr and settled in different villages of Goa make up the gauḍ sārasvat brāhmaṇ community.

description: The apparent $T^2$-temperature dependence of the London penetration depth in Sr$_2$RuO$_4$ is discussed on the basis of a multi-gap model with horizontal line nodes. The influence of the nodes in combination with nonlocal electromagnetic response leads to low-temperature behaviors as $-T^2\ln T$ in the London limit and as $T^2$ in the Pippard limit. These behaviors appear only at very low temperature. On the other hand, the interplay of the superconductivity of different bands is responsible for the observed $T^2$-like behavior over the wide temperature range. The experimental data can be fitted well with a set of material parameters as was used in the specific heat fitting.

description: Plasma profiling time of flight mass spectrometry (PP-TOFMS) has recently gained interest, as it enables the elemental profiling of semiconductor structures with high depth resolution in short acquisition times. As recently shown by Tempez et al., PP-TOFMS can be used to obtain the composition in the structures for modern field effect transistors [1]. There, the results were compared to conventional SIMS measurements. In the present study, we compare PP-TOFMS measurements of an Al-/In-/GaN quantum well multi stack to established micro- and nano-analysis techniques like cathodoluminescence (CL), scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). We show that PP-TOFMS is able to resolve the layer structure of the sample even more than 500 nm deep into the sample and allows the determination of a relative elemental composition with an accuracy of about 10 rel. %. Therefore, it is an extremely rapid alternative method to obtain semiconductor elemental depth profiles without expensive and time consuming sample preparation as it is needed for TEM. Besides, PP-TOFMS offers better depth resolution and more elemental information than for example electrochemical capacitance-voltage (ECV), as the acquisition of all elements occurs in parallel and not only electrically (ECV) or optically (CL) active elements are observed.

description: We investigate the supersymmetric electroweak corrections to the decay widths of the CP-odd and the heavy CP-even Higgs bosons into chargino or neutralino pair in the framework of the Minimal Supersymmetric Standard Model. The corrections involve the contributions of the order $O(α_{ew} m_{t(b)}^3/m_W^3)$, $O(α_{ew} m_{t(b)}^2/m_W^2)$ and $O(α_{ew} m_{t(b)}/m_W)$. The detailed calculations of the electroweak corrections to the following decay processes: $A^0/H^0 \to \tildeχ^+_1 \tildeχ^-_1$ and $A^0/H^0 \to \tildeχ^0_2 \tildeχ^0_2$ are presented in this paper. We find that these relative corrections maybe rather large quantitatively, and can exceed 10% in some regions of parameter space. The corrections to the decay $A^0/H^0 \to \tildeχ^0_1 \tildeχ^0_2$ can be obtained analogously, but our results show that they are very small and can be neglected.

description: Purpose: With the growing recognition of the role of coaching in competency-based medical education, many medical education training programs are investing significant resources into developing coaching programs. However, there is a lack of rigorous research on academic coaching programs in medical education and recommended coaching practices are based on expert opinion without incorporating the student perspective. The aim of this study was to investigate factors that affect a students’ perception of a successful coaching experience. Materials and method: This was a qualitative study performed in November 2018 at a medical school in the United States with a formal coaching program. Appreciative inquiry was the theoretical framework used to develop the question guide. The authors facilitated two focus groups and then used Colaizzi’s phenomenological analysis approach to analyze the transcripts. Results: A total of 21 students participated in the focus groups. The analysis revealed four themes that describe students’ perceptions of successful coaching experiences: coach attributes, relational skills, coaching skills, and utilization of coaching. Each of these themes had specific dimensions. Conclusions: The findings from this study illuminate the student stakeholder perspectives on successful coaching relationships, and should be considered when developing a coaching program and faculty development.

To obtain the effective one-band $t$-$t'$-$J$ model Hamiltonian, we perform the exact diagonalization of the three-band Hubbard model for the Ni$_5$O$_{16}$ cluster and map the low-energy spectra onto the effective one-band models. We find that the undoped NiO$_2$ plane is a Hubbard Mott insulator, and the doped holes primarily locate on Ni sites. The physics of the NiO$_2$ plane is a doped Mott insulator, described by the one-band $t$-$t'$-$J$ model with $t=265$~meV, $t'=-21$~meV and $J=28.6$~meV. We also discuss the electronic structure for the "self-doping" effect and heavy fermion behavior of electron pockets of Nd$^{3+}$ $5d$ character in Nd$_{1-x}$Sr$_x$NiO$_2$.

description: The It Takes a Region to Raise an Artist research offers the first in-depth survey of the visual arts in the East Midlands. Its purpose is to take stock of the region’s visual arts sector, identifying its key institutions, as well as its strengths and constraints, and to discover what members of the community might need in order to fulfil their professional and artistic potential.
The research was conducted through mapping existing provision and support, an online workforce survey, and conducting 15 one-to-one interviews. This new evidence will inform the development of It Takes a Region to Raise an Artist, CVAN EM’s future programme to further develop the East Midlands as a region where artists and visual arts practitioners can flourish – artistically and economically.
466 individual artists and visual arts practitioners participated in an online survey with 399 meeting the inclusion criteria of: a) professional (not self-defining as an amateur); b) living/working within the East Midlands; and c) self-identifying as a member of the visual arts community.
This research was funded by the Arts and Humanities Research Council through a 10-month Creative Economy Engagement Fellowship awarded by the Midlands4Cities Doctoral Training Partnership (M4C) in 2019. The research was undertaken by the CAMEo Research Institute for Cultural and Media Economies at the University of Leicester, in partnership with CVAN EM.

Fragile-to-strong transition and polyamorphism in the energy landscape of liquid silica

description: We study the static and dynamic properties of liquid silica over a wide range of temperature T and density using computer simulations. The results reveal a change in the potential energy landscape as T decreases that underlies a transition from a fragile liquid at high T to a strong liquid at low T. We also show that a specific heat anomaly is associated with this fragile-to-strong transition, and suggest that this anomaly is related to the polyamorphic behaviour of amorphous solid silica.

description: We report on an effort to improve the performance of superconducting radiofrequency cavities by the use of heat treatment in a temperature range sufficient to dissociate the natural surface oxide. We find that the residual resistance is significantly decreased, and we find an unexpected reduction in the BCS resistance. Together these result in extremely high quality factor values at relatively large accelerating fields Eacc ~20 MV/m: Q0 of 3-4x10^11 at <1.5 K and Q0 ~5x10^10 at 2.0 K. In one cavity, measurements of surface resistance versus temperature showed an extremely small residual resistance of just 0.63+/-0.06 nOhms at 16 MV/m. SIMS measurements confirm that the oxide was significantly dissociated, but they also show the presence of nitrogen after heat treatment. We also present studies of surface oxidation via exposure to air and to water, as well as the effects of very light surface removal via HF rinse. The possibilities for applications and the planned future development are discussed.

Energy Spectrum and Mass Composition around the Knee by EAS Measurements
Creators: name: Haungs, A.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Primary cosmic ray particles above energies of about 100 TeV are investigated by large-area ground based detector installations, observing various components of the development of extensive air-showers (EAS). By such an indirect access to the primary cosmic ray spectrum a steepening of the power-law falls off at around 3-5 PeV, known as the {\em knee} has been identified. Different experimental techniques are used to deduce mass- and energy-sensitive observables of EAS experiments. The experiments involve measurements of secondary particle distributions at various observation levels and of muons deep underground as well as of observables reconstructed by measuring the air Cherenkov light emitted with the shower development in the atmosphere. Recently methods for analysing multidimensional distributions get favoured since they are able to take into account the correlations between different observables and the influence of large intrinsic fluctuations of the air-shower development. Additionally the use of a larger set of observables provides the possibility to test simultaneously the consistency of the Monte-Carlo models underlying the reconstruction procedures. By many experiments the existence of the knee in the primary energy spectrum is confirmed and a tendency of an increasing mean mass above the knee energy is indicated. Recent results show that the knee originates from a decrease of the flux of light primary particles, whereas heavy cosmic ray particles seem to miss a kink in the energy range of 1 and 10 PeV.

Experimental study of granular surface flows via a fast camera: a continuous description

description: Depth averaged conservation equations are written for granular surface flows. Their application to the study of steady surface flows in a rotating drum allows to find experimentally the constitutive relations needed to close these equations from measurements of the velocity profile in the flowing layer at the center of the drum and from the flowing layer thickness and the static/flowing boundary profiles. The velocity varies linearly with depth, with a gradient independent of both the flowing layer thickness and the static/flowing boundary local slope. The first two closure relations relating the flow rate and the momentum flux to the flowing layer thickness and the slope are then deduced. Measurements of the profile of the flowing layer thickness and the static/flowing boundary in the whole drum explicitly give the last relation concerning the force acting on the flowing layer. Finally, these closure relations are compared to existing continuous models of surface flows.

description: The state-of-the-art error correcting codes are based on large random constructions (random graphs, random permutations, ...) and are decoded by linear-time iterative algorithms. Because of these features, they are remarkable examples of diluted mean-field spin glasses, both from the static and from the dynamic points of view. We analyze the behavior of decoding algorithms using the mapping onto statistical-physics models. This allows to understand the intrinsic (i.e. algorithm independent) features of this behavior.

description: The algebraic structure generated by the creation and annihilation operators of a system of m parafermions and n parabosons, satisfying the mutual parafermion relations, is known to be the Lie superalgebra osp(2m+1|2n). The Fock spaces of such systems are then certain lowest weight representations of osp(2m+1|2n). In the current paper, we investigate what happens when the number of parafermions and parabosons becomes infinite. In order to analyze the algebraic structure, and the Fock spaces, we first need to develop a new matrix form for the Lie superalgebra B(n,n)=osp(2n+1|2n), and construct a new Gelfand-Zetlin basis of the Fock spaces in the finite rank case. The new structures are appropriate for the situation $n\rightarrow\infty$. The algebra generated by the infinite number of creation and annihilation operators is $B(\infty,\infty)$, a well defined infinite rank version of the orthosymplectic Lie superalgebra. The Fock spaces are lowest weight representations of $B(\infty,\infty)$, with a basis consisting of particular row-stable Gelfand-Zetlin patterns.
