description: Fish consumers are increasingly looking for sustainable, safe and healthy products. The aim of this work is to evaluate the effect of informative messages on consumers’ acceptance of shelf-life extension on fresh packaged fish. In order to examine the effect of informative messages on consumers’ acceptance, an online survey on the acceptance of shelf life extension (SLE) technology by 10 days on fresh fish has been carried out. A sample of 530 consumers from Northern and Southern Italy was asked to evaluate a fictional portion of fresh Orata fillets presented as packaged by using SLE technology. The subsequent observation of the outcome of the survey highlights that different information strategies may moderate negative attitudes towards food technology applied to fish industry. The study presents a limitation that should be underlined. As the survey was conducted in the Italian context, results may lack of external validity. Thus, we expect to integrate the information obtained from this preliminary study with new surveys that could be focused on understanding the determinants of this attitudinal structure. Thus, studies investigating the interventions to increase food technology acceptance may help to reduce consumers’ skepticism towards food innovation.

description: Vertex cover is one of the classical NP-complete problems in theoretical computer science. A vertex cover of a graph is a subset of vertices such that for each edge at least one of the two endpoints is contained in the subset. When studied on Erdos-Renyi random graphs (with connectivity c) one observes a threshold behavior: In the thermodynamic limit the size of the minimal vertex cover is independent of the specific graph. Recent analytical studies show that on the phase boundary, for small connectivities c

description: This paper studies the influence of logarithmic functions in policy gradient deep reinforcement learning (RL) methods, a subject previously under-emphasized in the field. It delves into how different logarithmic bases, specifically loge, log2, and log10, influence the efficiency of policy gradient methods. We analyze the role of these logarithmic functions and their gradients when using Stochastic Gradient Descent as the optimizer in deep RL. Experimental results show that the choice of the logarithmic base influences the policy gradient methods. loge and log2 are generally more effective than log10 in deep RL algo- rithms, but log10 exhibits more stability. Based on analysis and experimental results, we propose the Logarithmic Basis Policy Gradient (LBPG) and Adaptive LBPG algorithms to enhance policy gradient methods. LBPG denotes policy gradient methods with loge, log2, and log10 as the logarithmic base, respectively. Furthermore, Adaptive LBPG dynamically selects logarithmic basis among loge, log2, and log10 based on the variance-to-mean ratio of returns, to optimize speed and stability. Experimental results show the importance of choosing appropriate logarithmic functions for policy gradient RL methods and highlight Adaptive LBPG’s potential to refine learning in deep RL tasks.
Perspective on Afterglows: Numerically Computed Views, Lightcurves and the Analysis of Homogeneous and Structured Jets with Lateral Expansion

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Herein I present numerical calculations of lightcurves of homogeneous and structured afterglows with various lateral expansion rates as seen from any vantage point. Such calculations allow for direct simulation of observable quantities for complex afterglows with arbitrary energy distributions and lateral expansion paradigms. A simple, causal model is suggested for lateral expansion of the jet as it evolves; namely, that the lateral expansion kinetic energy derives from the forward kinetic energy. As such the homogeneous jet model shows that lateral expansion is important at all times in the afterglow evolution and that analytical scaling laws do a poor job at describing the afterglow decay before and after the break. In particular, I find that lateral expansion does not cause a break in the lightcurve as had been predicted. A primary purpose of this paper is to study structured afterglows, which do a good job of reproducing global relationships and correlations in the data and thus suggest the possibility of a universal afterglow model. Simulations of structured jets show a general trend in which jet breaks become more pronounced with increasing viewing angle with respect to the jet axis. In fact, under certain conditions a bump can occur in the lightcurve at the jet break time. I derive scaling relations for this bump and suggest that it may be a source of some bumps in observed lightcurves such as that of GRB 000301C. A couple of lateral expansion models are tested over a range of efficiencies and viewing angles and it is found that lateral expansion can, in some cases, substantially sharpen the jet break. I show flux surface contour maps and simulated images of the afterglows which give insight into how they evolve and determine their lightcurves.

For this purpose we consider a prototype metallic phase of B$_{13}$C$_2$. We show that in this compound the Boron icosahedral units are mainly responsible for the large phonon frequencies logarithmic average, 65.8 meV, and the moderate electron-phonon coupling 0.8. We suggest that this high critical temperature could be a general feature of hole doped boron icosahedral solids.

description: We give predictions for the up-down asymmetry in the Nadir angle dependence of the ratio Nmu/Ne of the rates of the mu-like and e-like multi-GeV events measured in water-Cerenkov detectors (Super-Kamiokande, etc.) in the case of 3-neutrino oscillations of the atmospheric nu_e (antinu_e) and nu_mu (antinu_mu), driven by one neutrino mass squared difference, |Delta m^2_{atm}| = |Delta m^2_{31}| ~ (2.0 - 3.0) 10^{-3} eV^2 >> Delta m^2_{21} = Delta m^2_{sol}. This ratio is particularly sensitive to the Earth matter effects in the atmospheric neutrino oscillations, and thus to the values of sin^2(theta13) and sin^2(theta23), theta13 and theta23 being the neutrino mixing angle limited by the CHOOZ and Palo Verde experiments and that responsible for the dominant atmospheric nu_mu -> nu_tau (antinu_mu -> antinu_tau) oscillations, respectively. It is also sensitive to the type of neutrino mass spectrum which can be with normal (Delta m^2_{atm} > 0) or with inverted (Delta m^2_{atm} < 0) hierarchy.

description: This paper examines the impact of alcohol prohibition policies on child educational outcomes using the variation in location, timing, and intensity of alcohol prohibition laws across different states in India. I find that the imposition of complete alcohol bans resulted in an increase of 0.28 years of schooling, while partial bans that prohibited only cheaper varieties of alcohol resulted in a reduction of -0.25 years on average among individuals who were exposed to these bans during in utero, infancy, preschool or school-going age (0 - 18 years of age). I find that the alcohol laws have an effect only on individuals who were exposed to these changes during their school-going age, but have no impact on the older cohorts . Finally, I use data from national consumption expenditure surveys to show that these results are driven by shifts in household budgetary allocation. Using a triple-difference strategy (exploiting the fact that Muslim households are not affected by alcohol policy changes due to religious rules that proscribe alcohol consumption), I find that households exposed to partial prohibition laws reduce their share of expenditure on education goods by nearly 17 percent relative to the sample mean, while complete prohibition shows no effect on educational investments.

description: In this paper we give an analytic proof of the identity $A_{5,3,3}(n) =B^0_{5,3,3}(n)$, where $A_{5,3,3}(n)$ counts the number of partitions of $n$ subject to certain restrictions on their parts, and $B^0_{5,3,3}(n)$ counts the number of partitions of $n$ subject to certain other restrictions on their parts, both too long to be stated in the abstract. Our proof establishes actually a refinement of that partition identity. The original identity was first discovered by the first author jointly with M. Ruby Salestina and S. R. Sudarshan in ["A new theorem on partitions," Proc. Int. Conference on Special Functions, IMSC, Chennai, India, September 23-27, 2002; to appear], where it was also given a combinatorial proof, thus responding a question of Andrews.

description: Due to the fast-growing volume of text documents and reviews in recent years, current analyzing techniques are not competent enough to meet the users' needs. Using feature selection techniques not only support to understand data better but also lead to higher speed and also accuracy. In this article, the Whale Optimization algorithm is considered and applied to the search for the optimum subset of features. As known, F-measure is a metric based on precision and recall that is very popular in comparing classifiers. For the evaluation and comparison of the experimental results, PART, random tree, random forest, and RBF network classification algorithms have been applied to the different number of features. Experimental results show that the random forest has the best accuracy on 500 features. Keywords: Feature selection, Whale Optimization algorithm, Selecting optimal, Classification algorithm

description: Within the premise of canonical quantisation, we re-examine the quantum structure of bosonic tensionless string theory. In the classical theory, the worldsheet metric degenerates and the Bondi-Metnzer-Sachs (BMS) algebra arises as the residual symmetries on fixing the tensionless equivalent of the conformal gauge. In the quantum regime, we find, on careful examination, that there are multiple ways to impose constraints to restrict the physical Hilbert space, which in turn lead to three distinct choices of tensionless vacua. We analyse these vacua in detail, commenting on various aspects like the central charges and the spectrum around each of them.

title: Database systems: different interfaces for different users
Creators: name: Jennings, Frances
Publisher: name: The Open University
Year: 1991

description: Users of database systems, especially public information systems, can vary widely in their aptitudes and experience with using computer systems. This study investigates whether users with different aptitudes and experience are suited to database system interfaces with different dialogue styles. Experiments were conducted to examine the performance of users on interfaces with different dialogue styles. The results suggested that dialogue styles which aid navigation through the database, and which constrain the dialogue, are suitable for users with both a low spatial ability and a low experience of using command language style interfaces. However dialogue styles which offer little assistance with navigation, and which allow an open and flexible dialogue, are suitable for users with a high spatial ability whatever their experience, and for users with a low spatial ability but high experience of using command language style interfaces. The suggestion that different users of a database system are suited to interfaces with different dialogue styles, raises the issue of how to present different users with different interfaces. The study investigates the possibility of producing an adaptive database system, which automatically provides each user with the interface which suits them. A demonstration adaptive version of one of the databases used in the experimental work was developed. The system was designed to present an interface which aided navigation, and constrained the dialogue, to users with low spatial ability and low actual and potential experience of using command style interfaces. The system was designed to present an interface allowing an open and flexible dialogue to users with high spatial ability, or low spatial ability but high actual or potential experience of using command style interfaces. The adaptive system was constructed with the aid of a prototype 'adaptive system shell", designed to provide a generic architecture for the mechanisms necessary for an adaptive system.

description: Ultimate bounds on the maximum operating frequency of networks of quantum dot cellular automata devices have yet to be established. We consider the adiabaticity of such networks in the two-state approximation where clocking is achieved via modulation of the inter-dot tunneling barriers. Estimates of the maximum operating frequency that would allow a 99% probability of observing the correct logical output are presented for a subset of the basic components used in QCA network design. Simulations are performed both in the coherent limit and for a simple dissipative model. We approach the problem of tunnel-based clocking from the perspective of quantum annealing, and present an improved clocking schedule allowing for faster operation. Using an analytical solution for driven QCA wires, we show that the maximum operating frequency in the coherent limit falls off with the square of the wire length, potentially limiting the size of clocked regions.

description: With the consequential threats of global climate change expected to alter ecosystems and societies around the world, the University of British Columbia (UBC) has listed climate action as one of their priorities. With UBC currently planning their next steps in addressing climate change through their development of the Climate Action Plan 2030 (CAP 2030) it is critical that UBC addresses biodiversity in this plan. CAP 2030 currently lacks sufficient consideration for biodiversity as a key aspect for mitigating and adapting to climate change. Therefore, the purpose of this report is to inform UBC of the importance of biodiversity to all aspects of the UBC community. We have chosen four pillars that UBC should consider when planning for biodiversity conservation. These pillars are social, cultural, economic, and environmental perspectives for biodiversity. Our team has done a literature review of peer reviewed papers addressing the interconnections between biodiversity and each of our four chosen pillars. Additionally, we reviewed UBC’s current actions that address biodiversity. In consultation with UBC’s Social Ecological Economic Development Studies (SEEDS) Sustainability Program, we have prepared this report to guide UBC in their integration of biodiversity action into CAP 2030. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC. Furthermore readers should bear in mind that these reports may not reflect the current status of activities at UBC.

Primordial bound systems of superheavy particles as the source of ultra-high energy cosmic rays

description: Annihilation of superheavy particles in primordial bound systems is considered as the source of Ultra High Energy Cosmic Rays (UHECR).Charge conservation makes them to be produced in pairs, and the estimated separation of particle and antiparticle in such pair is shown to be in some cases much smaller than the average separation determined by the averaged number density of considered particles. If the new U(1) charge is the source of a long range field similar to electromagnetic field, the particle and antiparticle, possessing that charge, can form primordial bound system with annihilation timescale, which can satisfy the conditions, assumed for this type of UHECR sources. These conditions severely constrain the possible properties of considered particles. So, the proposed mechanism of UHECR origin is impossible to realise, if the U(1) charged particles share ordinary weak, strong or electromagnetic interactions. It makes the proposed mechanism of pairing and binding of superheavy U(1) charged particles an effective theoretical tool in the probes of the physics of very early Universe and of the hidden sector of particle theory, underlying it.

description: A simple way to construct models with early cosmological Genesis epoch is to employ bosonic fields whose Lagrangians transform homogeneously under scaling transformation. We show that in these theories, for a range of parameters defining the Lagrangian, there exists a homogeneous power-law solution in flat space-time, whose energy density vanishes, while pressure is negative (power-law Genesis). We find the condition for the legitimacy of the classical field theory description of such a situation. We note that this condition does not hold for our earlier Genesis model with vector field. We construct another model with vector field and power-law background solution in flat space-time, which is legitimately treated within classical field theory, violates the NEC and is stable. Upon turning on gravity, this model describes the early Genesis stage.

description: As a new type of self-healing material, room-temperature liquid metal (LM) composed of Ga, In and Sn is a promising anode in lithium-ion batteries (LIBs). It is difficult to directly prepare an electrode slurry with pure LM. Here, the LM electrode slurry was successfully prepared by simple high-speed stirring method. The LM in the slurry was evenly distributed in the form of liquid particles (average size 100 μm) and no aggregation occurred. The initial discharge specific capacity of LM is 1148 mAh g-1, and the stable discharge specific capacity is 350 mAh g-1. Cyclic voltammetry measurements show that three pairs of obvious reduction peaks and oxidation occur in LM anodes at 0.37 V,0.67 V,1.02 V and 0.72 V,0.79 V,0.97 V. In the process of lithium insertion, the LM undergoes a liquid-solid phase transition, and when it is delithiated, it will be converted into a liquid phase. The SEI film consumed active lithium and electrolyte during the long cycle, resulting in loss of reversible capacity.

 Comments
 This species is known only from an immature female specimen collected in Nicobar Islands (Thorell 1891). In our opinion, identification of Cheiracanthium spp. on the basis of immature specimens is extremely difficult, and in most cases, impossible. However, in some cases, it is possible for immature (=subadult) females. We refrain from establishing a ‘ nomen dubium ’ without a detailed study of the type.

 Comments
 This species was originally described from Punjab State, India (Tikader 1976) from both sexes. The conspecificity of the two species, C. melanostomum and C. sadanai, is not at all certain. The respective suggestion by Deeleman-Reinhold (2001, p. 231) is not reasonable. In the original description of C. sadanai it is indicated that ‘cephalothorax, abdomen and legs light green’ (Tikader 1976, p. 176), while in the original description of C. melanostomum, it is indicated that the cephalothorax colouration ranges from testaceous to dark testaceous (Thorell 1895, p. 44). According to the redescription by Majumder and Tikader (1991), Indian specimens of C. melanostomum also have a colour pattern (‘cephalothorax, legs and abdomen light brown’, cf. Majumder and Tikader 1991, p. 63) different from that of C. sadanai. Other potential distinguishing characteristics are indicated in the definitive key of Majumder and Tikader (1991, p. 54–56). However, currently, there is no publication that includes illustrations that allow an unambiguous definition of either C. melanostomum or C. sadanai according to the characters of the copulatory organs (all illustrations of these species in the relevant literature are too small and/or hard to interpret). Moreover, there is no indication that the types of C. sadanai had been re-examined by any of the subsequent authors (that either treated C. melanostomum or C. sadanai). Unfortunately, due to strict regulations in India, the type specimens were not available for this study either.

description: According to Mukai, any prime Fano threefold X of genus 7 is a linear section of the spinor tenfold in the projectivized half-spinor space of Spin(10). The orthogonal linear section of the spinor tenfold is a canonical genus-7 curve G, and the intermediate Jacobian J(X) is isomorphic to the Jacobian of G. It is proven that, for a generic X, the Abel-Jacobi map of the family of elliptic sextics on X factors through the moduli space of rank-2 vector bundles with c_1=-K_X and deg c_2=6 and that the latter is birational to the singular locus of the theta divisor of J(X).

description: Spontaneous motion of an oil droplet driven by chemical nonequilibricity is reported. It is shown that the droplet undergoes regular rhythmic motion under appropriately designed boundary conditions, whereas it exhibits random motion in an isotropic environment. This study is a novel manifestation on the direct energy transformation of chemical energy into regular spatial-motion under isothermal conditions. A simple mathematical equation including noise reproduces the essential feature of the transition from irregularity into periodic regular motion. Our results will inspire the theoretical study on the mechanism of molecular motors in living matter, working under significant influence of thermal fluctuation.

description: We examine a quantum dot with $N_{\rm dot}$ levels which is strongly coupled to leads for varying number of channels $N$ in the leads. It is shown both analytically and numerically that for strong couplings between the dot and the leads, at least $N_{\rm dot}-N$ bound states (akin to subradiant states in optics) remain on the dot. These bound states exhibit discrete charging and, for a significant range of charging energies, strong Coulomb blockade behavior as function of the chemical potential. The physics changes for large charging energy where the same (superradiant) state is repeatedly charged.

description: We present new chemo--kinematics of the Hercules dwarf galaxy based on Keck II-- DEIMOS spectroscopy. Our 21 confirmed members have a systemic velocity of $v_{\mathrm{Herc}}=46.4\pm1.3$ kms$^{-1}$ and a velocity dispersion $σ_{v,\mathrm{Herc}}=4.4^{+1.4}_{-1.2}$ kms$^{-1}$. From the strength of the Ca II triplet, we obtain a metallicity of [Fe/H]= $-2.48\pm0.19$ dex and dispersion of $σ_{\rm{[Fe/H]}}= 0.63^{+0.18}_{-0.13}$ dex. This makes Hercules a particularly metal--poor galaxy, placing it slightly below the standard mass--metallicity relation. Previous photometric and spectroscopic evidence suggests that Hercules is tidally disrupting and may be on a highly radial orbit. From our identified members, we measure no significant velocity gradient. By cross--matching with the second \textit{Gaia} data release, we determine an uncertainty--weighted mean proper motion of $μ_α^*=μ_α\cos(δ)=-0.153\pm{0.074}$ mas yr$^{-1}$, $μ_δ=-0.397\pm0.063$ mas yr$^{-1}$. This proper motion is slightly misaligned with the elongation of Hercules, in contrast to models which suggest that any tidal debris should be well aligned with the orbital path. Future observations may resolve this tension.

description: The two-dimensional interpolating readout concept of the Virtual-Pixel detector (ViP detector) goes along with an enormous reduction of electronic channels compared to pure pixel devices. However, the special concept of the readout structure demands for adequate position reconstruction methods. Theoretical considerations reflecting the choice and the combination of linear algorithms with emphasis on correct position reconstruction and spatial resolution are presented. A subsequent two-dimensional coordinate transformation further improves the image response of the system. Measured images show how far the theoretical predictions of the simulations can be verified and to what extent they can be used to improve the position reconstruction.

title: The effect of some stressors on the metabolism of the plaice, Pleuronectes platessa L.
Creators: name: White, Ann
Publisher: name: The Open University
Year: 1991

description: The influence of environmental stressors on the concentrations of various serum components was examined in the plaice (Pleuronectes platessa L.). These factors included capture, transportation and short-term starvation following arrival in the aquarium, where the effects of normal and exacerbated disturbance were also examined. The serum lipid class and concentration in male and female plaice caught at various seasons was investigated in relation to the composition of the gonads, as an example of the effects of the reproductive cycle on the nature of the circulating lipids. Plaice were fed fresh mussel flesh for 7 months, at the end of which time, serum/plasma components were measured after 24 h without food. No significant differences were found between those values and concentrations found in wild fish 24 to 48 h post-capture (without feeding). After capture and transportation to the aquarium, plaice were maintained for 15 days without feeding. The decrease in glucose and cortisol levels are perhaps due more to recovery from capture and transportation, rather than to lack of food. Only cortisol levels proved sensitive to routine aquarium disturbance and in fish exposed to agitation for 1 h, but significant differences between short- and long-term physical disturbance over a 24 h period were also found for serum glucose, total cholesterol and free cholesterol. Serum non-esterified fatty acids (NEFA) concentrations, however, began to increase 3 h after the onset of disturbance, and high levels were sustained in fish from both regimes over the 24 h period. In plaice under reduced oxygen conditions for a short period of time, increases were found in circulating levels of NEFA, cortisol, free cholesterol and lactate, but there was a decrease in the serum glucose concentration, when compared to control fish. The intraperitoneal (i.p.) injection of cortisol had no significant effect on serum components measured after 24 h and 4 days, whereas injection of adrenalin caused an increase in serum NEFA, glucose and cortisol concentrations after 24 h and a decrease in serum NEFA after 4 days. The i.p. injection of endotoxin resulted in a decrease in serum NEFA (4 days) and glucose (24 h) levels, and an increase in serum cortisol (24 h), when compared with saline injected controls. Total lipid, total cholesterol, free cholesterol, triglycerides, phospholipids and NEFA were measured using commercial kits, validated against standard reference methods.

description: With growing investment in consumer augmented reality (AR) headsets and glasses, wearable AR is moving from niche applications to everyday use. However, current research primarily examines AR in controlled settings, offering limited insights into its use in real-world daily life. To address this gap, we adopt a digital ethnographic approach, analysing 27 hours of 112 YouTube videos featuring early adopters. These videos capture usage ranging from continuous periods of hours to intermittent use over weeks and months. Our analysis shows that currently, wearable AR is primarily used for media consumption and gaming. While productivity is a desired use case, frequent use is constrained by current hardware limitations and the nascent application ecosystem. Users seek continuity in their digital experience, desiring functionalities similar to those on smartphones, tablets, or computers. We propose implications for everyday AR development that promote adoption while ensuring safe, ethical, and socially-aware integration into daily life.
QCD thermodynamics from an imaginary mu_B: results on the four flavor lattice model

description: We study four flavor QCD at nonzero temperature and density by analytic continuation from an imaginary chemical potential. The explored region is T = 0.95 T_c < T < 3.5 T_c, and the baryochemical potentials range from 0 to approx. 500 MeV. Observables include the number density, the order parameter for chiral symmetry, and the pressure, which is calculated via an integral method at fixed temperature and quark mass. The simulations are carried out on a 16^3 X 4 lattice, and the mass dependence of the results is estimated by exploiting the Maxwell relations. In the hadronic region we confirm that the results are consistent with a simple resonance hadron gas model, and we estimate the critical density by combining the results for the number density with those for the critical line. In the hot phase, above the endpoint of the Roberge-Weiss transition T_E approx 1.1 T_c the results are consistent with a free lattice model with a fixed effective number of flavor slightly different from four. We confirm that confinement and chiral symmetry are coincident by a further analysis of the critical line, and we discuss the interrelation between thermodynamics and critical behavior. We comment on the strength and weakness of the method, and propose further developments.
