description: No abstracts are to be cited without prior reference to the author.In Northwest Africa, pelagic resources are an essential economic activity, particularly off Mauritania which concentrates about 90% of catches. To honor the fact that acoustic densities are reliable observations of the order of magnitude of the abundances rather than precise measurements of fish densities, we apply non-linear geostatistics to produce i) patchworks of classes of densities and ii) indices of abundances from acoustic data collected during yearly surveys of R/V Fridjoff Nansen from 1995 to 2006. This method, developed in the mining sector, has so far seldom been applied to fisheries. We show that it provides valuable and reliable results when applied to abundance indices for pelagic fisheries in Northwest Africa. Simple and cross-variograms of indicators variables based on four different thresholds of densities exhibit a year to year stable spatial structuration of classes of densities. Our results indicate also that (1) after a period of fluctuation between 1995-2000, adundance indices exhibit a slow and continuous increasing trend from 2001 to 2006, and that (2) from 2001 to 2006, the geographical distribution of high abundance areas has become wider by extending further offshore each year, roughly from 0.56 miles in 2001 to 0.92 miles in 2006.

description: The paper is largely of a review nature. It considers two main methods used to study stability and obtain appropriate quantitative estimates of perturbations of (inhomogeneous) Markov chains with continuous time and a finite or countable state space. An approach is described to the construction of perturbation estimates for the main five classes of such chains associated with queuing models. Several specific models are considered for which the limit characteristics and perturbation bounds for admissible "perturbed" processes are calculated.

description: Ag and Ni/ZnO photocatalyst nanostructures were successfully synthesized by a sol–gel method. In this work, the photocatalyst sample was systematically studied based on several factors affecting the performance of photocatalyst which are size, morphology, band gap, textural properties and the number of active sites presence on the surface of the nanocatalyst. X-ray diffraction revealed that Ag/ZnO nanomaterials experienced multiple phases, meanwhile for Ni/ZnO the phase of nanomaterials were pure and single phase for stochiometry less than 5%. Field emission scanning electron microscope (FESEM) showed almost all of the synthesized nanomaterials possessed a mixture of nanorods and spherical-like shape morphology. The Ag/ZnO showed high photocatalytic activity, producing at least 14th trials of nanocatalyst reusability on degradation of methyl orange under UV irradiation. Interestingly, this phenomenon was not observed in larger surface area of Ni/ZnO nanomaterials which supposedly favour photocatalytic activity, but instead producing poor photocatalytic performance. The main reason were studied and exposed by temperature-programmed desorption of carbon dioxide (TPD–CO2) which showed that incorporation of Ag into ZnO lattice has enhanced the number of active sites on the surface of the nanocatalyst. Whereas incorporation of Ni in ZnO has lowered the number of active sites with respect to undoped ZnO. Active sites measurement is effective and significant, providing opportunities in developing an intensive study as an additional factor.

description: In this letter, an age of information (AoI)-aware transmission power and resource block (RB) allocation technique for vehicular communication networks is proposed. Due to the highly dynamic nature of vehicular networks, gaining a prior knowledge about the network dynamics, i.e., wireless channels and interference, in order to allocate resources, is challenging. Therefore, to effectively allocate power and RBs, the proposed approach allows the network to actively learn its dynamics by balancing a tradeoff between minimizing the probability that the vehicles' AoI exceeds a predefined threshold and maximizing the knowledge about the network dynamics. In this regard, using a Gaussian process regression (GPR) approach, an online decentralized strategy is proposed to actively learn the network dynamics, estimate the vehicles' future AoI, and proactively allocate resources. Simulation results show a significant improvement in terms of AoI violation probability, compared to several baselines, with a reduction of at least 50%.

description: The focus of the paper is to analyze the problems and issues in transformation to organic tea production, price benefits that can be accrued, present level of organic production and farmers’ awareness and adoption using both the primary and secondary data collected from various published sources and personal interview of the sample of farmers. The sample of farmers comprises of 100 beneficiaries of Participatory Guarantee System of India (PGSIndia), four Small Tea Growers Societies, Certified Organic Tea Estate sector and three organic large tea growers including Small Tea Farmers’ Producer Company. Time series data on domestic prices, export prices for tea and organic tea, area under tea cultivation, productivity - before and after conversion were collected and analyzed. Though organic tea production is gaining momentum among the small tea growers, yield reduction after conversion is a major threat. Despite the fact that there is a yield reduction, our sample of organic tea growers were benefitted from higher remunerative price for their green tea leaves due to adoption of quality tea plucking practices with opinion that formal certification would help them to realize better prices due to market acceptance. As long as Small Tea Growers (STGs) could be able to realize premium market prices, they are ready for conversion. We also found from the soil sample analysis that there would be long term beneficial impact of organic tea cultivation on soil and productivity. Export price for organic tea is twice than that of normal tea but export share was minimal emphasizing the need for higher level of export for which formal certification is crucial since the organic tea exporters cannot source tea from uncertified STG organic farms. The awareness for certification is lacking though trainings and demonstration are being carried out by the various agencies. In this context of crisis of continuous price fall and loosing the export markets due to competitiveness, organic production is one of the alternatives among the STGs to have decent livelihood in the Nilgiris district of Tamil Nadu State of India. Creating awareness and resorting to formal certification to compete in the global market are warranted. The role of Primary Producers Societies (PPS) is critical in enforcing the quality for organic tea production and marketing.

description: $f(T,B)$ teleparallel gravity is a recently proposed straightforward generalization of the popular $f(T)$ teleparallel gravity by the incorporation of a boundary term $B=\frac{2}{e}\partial_{i}(e T ^{i}) = \bigtriangledown_{i}T^{i}$ where $T$ denote the torsion scalar \cite{ftb13}. In this work, I investigate the viability of some well motivated $f(T,B)$ teleparallel gravity models of the forms $f=αB^n+βT^m$, $f=αB^n T^m$ and $f=α\log (B)+βT$ where $α, β, n$ and $m$ are free parameters from the inequalities imposed the the weak energy condition. I use the recent estimates of Hubble, deceleration, jerk and snap parameters in finding corners in parameter spaces for the cosmological models for which the energy density remain positive and the weak energy condition ( i.e, $ρ+p \geq 0$, where $p$ and $ρ$ represent respectively the cosmological pressure and energy density) attains a minute positive value, as this implies the EoS parameter $ω= p/ρ\simeq-1$ and therefore consistent with an accelerating universe.

description: No abstracts are to be cited without prior reference to the author.Juvenile Atlantic bluefin tunas perform feeding migrations every summer to the Bay of Biscay, where juvenile anchovy constitutes their quasi-exclusive prey in the second half of the summer. Uncertainties regarding the stock abundance of bluefin tuna and their predation impacts on juvenile anchovy raised the need to develop reliable abundance indices for bluefin tuna in the Bay of Biscay. Due to the behaviour of this large pelagic predator (patchy distribution, fast displacements, possible influences of feeding strategy on schooling behaviour), the possibility of acoustic surveys directed to bluefin tuna was assessed by an experimental survey

description: It is possible to learn about the orientation of a star's rotation axis by combining measurements of the star's rotation velocity ($v$) and its projection onto our line of sight ($v\sin i$). This idea has found many applications, including the investigation of the obliquities of stars with transiting planets. Here, we present a method for the probabilistic inference of the inclination of the star's rotation axis based on independent data sets that constrain $v$ and $v\sin i$. We also correct several errors and misconceptions that appear in the literature.

title: Development of Gold Nanocarriers to Deliver Proteins and Peptides to the CNS
Creators: name: McQuaid, Conor
Publisher: name: The Open University
Year: 2023

description: Treatment of many CNS disorders, specifically neurodegenerative disorders are severely limited at present, and with an increase in the aging population, research into an effective treatment is necessary. A major issue is that many therapeutic agents cannot access the brain, due to a structure termed the blood brain barrier (BBB), which excludes many potential therapeutic drugs from the CNS of the drugs that could possibly treat these disorders. Cellular delivery of bioactive molecules e.g. antibodies, peptides and cytokines are a growing area of research due to their possible therapeutic potential. There have been several cytokines which have been successfully used in experimental models of many neurodegenerative diseases but have had difficulty in being translated into clinical trials. These cytokines do not cross the BBB by themselves but if attached to an effective nanocarrier that is able to cross this barrier, could be translated into a much-needed treatment. Gold Nanoparticles (AuNP) have been selected due to their numerous useful characteristics, such as easy production, biological compatibility and chemical stability. Previous research has shown that glucose derived-coated gold nanoparticles can bind to, and cross human brain endothelial cells in vitro and rat brain endothelial cells in vivo.

 15 formulations of ligand coated AuNPs were investigated using a simple model of the BBB, to determine which formulation could cross the brain endothelium most efficiently. PEGamine/GalactoseC2 and GlucoseC2 ligand coated AuNPs were able to cross most effectively and were taken forward for further experimentation; GalactoseC2 coated AuNPs were used as a control ligand coating.

 BDNF, the chosen cytokine of interest for attachment to AuNP, was mutagenically altered (Histidine→Cysteine) in the His tag region of a plasmid used to produce recombinant human BDNF to produce a free thiol group on the Cysteine allowing a place-exchange reaction onto the surface of the AuNP. We optimized the production of our modified BDNF (BDNF-H9C) and developed effective techniques to measure the quantity and biological activity of the protein produced (ELISA and TrK-B Assay). However insufficient quantity of BDNF-H9C could be produced from transfected cells and purified to perform an exchange reaction.

 A series of peptides was analysed for their ability to bind the transferrin receptor expressed on brain endothelium in vitro (hCMEC/D3 cells). One strongly-binding peptide was selected for attachment to AuNPs and this was found to increase the amount of AuNP that crossed a BBB model.

description: Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report on the measurement of the ratio of semileptonic rates Γ(D+ > ANTI-K pi mu+ nu)/Γ(D+ > ANTI-K0 mu+ nu)= 0.625 +/- 0.045 +/- 0.034. Allowing for the K pi S-wave interference measured previously by FOCUS, we extract the vector to pseudoscalar ratio Γ(D+ > ANTI-K*0 mu+ nu)/Γ(D+ > ANTI-K0 mu+ nu)= 0.594 +/- 0.043 +/- 0.033 and the ratio Γ(D+ > ANTI-K0 mu+ nu)/Γ(D+ > K- pi+ pi+)= 1.019 +/- 0.076 +/- 0.065. Our results show a lower ratio for Γ(D > K* \ell nu})/Γ(D > K \ell nu) than has been reported recently and indicate the current world average branching fractions for the decays D+ >ANTI-K0(mu+, e+) nu are low. Using the PDG world average for B(D+ > K- pi+ pi+) we extract B(D+ > ANIT-K0 mu+ nu)=(9.27 +/- 0.69 +/- 0.59 +/- 0.61)%.

description: We introduce a two-dimensional non-Hermitian lattice model with an imaginary magnetic field and elucidate various unique features which are absent in Hermitian lattice models with real magnetic fields. To describe the imaginary magnetic field, we consider both the Landau gauge and the symmetric gauge, which are related by a generalized gauge transformation, changing not only the phase but also the amplitude of the wave function. We discuss the complex energy spectrum and the non-Hermitian Aharonov-Bohm effect as examples of properties which are due to the imaginary magnetic field independent of the generalized gauge transformation. We show that the energy spectrum does not converge as the lattice size is made larger, which comes from the intrinsic nonperiodicity of the model. However, we have found that the energy spectrum does converge if one fixes the length of one side and makes the other side longer; this asymptotic behavior can be understood in the framework of the non-Bloch band theory. We also find an analog of the Aharonov-Bohm effect; the net change of the norm of the wave function upon adiabatically forming a closed path is determined by the imaginary magnetic flux enclosed by the path, which provides an experimentally observable feature of the imaginary magnetic field.

description: The thermodynamic definition of entropy can be extended to nonequilibrium systems based on its relation to information. To apply this definition in practice requires access to the physical system's microstates, which may be prohibitively inefficient to sample or difficult to obtain experimentally. It is beneficial, therefore, to relate the entropy to other integrated properties which are accessible out of equilibrium. We focus on the structure factor, which describes the spatial correlations of density fluctuations and can be directly measured by scattering. The information gained by a given structure factor regarding an otherwise unknown system provides an upper bound for the system's entropy. We find that the maximum-entropy model corresponds to an equilibrium system with an effective pair-interaction. Approximate closed-form relations for the effective pair-potential and the resulting entropy in terms of the structure factor are obtained. As examples, the relations are used to estimate the entropy of an exactly solvable model and two simulated systems out of equilibrium. The focus is on low-dimensional examples, where our method, as well as a recently proposed compression-based one, can be tested against a rigorous direct-sampling technique. The entropy inferred from the structure factor is found to be consistent with the other methods, superior for larger system sizes, and accurate in identifying global transitions. Our approach allows for extensions of the theory to more complex systems and to higher-order correlations.

description: The large number of variables in M3 provides a unique opportunity to study an extensive sample of variables with the same apparent distance modulus. Recent, high accuracy CCD time series of the variables show that according to their mean magnitudes and light curve shapes, the variables belong to four separate groups. Comparing the properties of these groups (magnitudes and periods) with horizontal branch evolutionary models, we conclude that these samples can be unambiguously identified with different stages of the horizontal branch stellar evolution. Stars close to the zero age horizontal branch (ZAHB) show Oosterhoff I type properties, while the brightest stars have Oosterhoff II type statistics regarding their mean periods and RRab/RRc number ratios. This finding strengthens the earlier suggestion of Lee et al. (1990) connecting the Oosterhoff dichotomy to evolutionary effects, however, it is unexpected to find large samples of both of the Oosterhoff type within a single cluster, which is, moreover, the prototype of the Oosterhoff I class globular clusters. The very slight difference between the Fourier parameters of the stars (at a given period) in the three fainter samples spanning over about 0.15 mag range in M_V points to the limitations of any empirical methods which aim to determine accurate absolute magnitudes of RR Lyrae stars solely from the Fourier parameters of the light curves.

description: The digital age and stronger focus on sustainability of energy production have brought a wave of new advancements to the world. Nonetheless, the traditional fossil fuels will continue to be the main source of energy for the next decades. However, the oil and gas industry must adapt to the new era and increase its agility to quickly respond to the fluctuations in supply and demand in upcoming and developing markets. In this paper, a literature review is first presented describing the challenges and opportunities faced in the industry. Two strategies are presented which have shown to propel forward other industries and could help the oil and gas industry adapt to current times. Following this literature review, the findings will be applied to the development of a novel flexible hydrocarbon storage solution. The intention of this project is to present improvements, by which the industry could become more agile and responsive by offering a more economic and quick-to-build solution to replace carbon steel storage tanks. The implementation of such a solution would substantially improve the balance of economic, environmental, and social focus of the industry and offer a step forward starting from the midstream sector, the one responsible for moving hydrocarbons to where they are needed.

description: A computational study of the Electron Paramagnetic Resonance (EPR) $g$-tensors and hyperfine tensors of Li and Ga vacancies in LiGaO$_2$ is presented. Density Functinal Theory (DFT) calculations are carried out of the Ga and Li vacancies using the DFT+U approach in the charge states which carry an unpaired spin. In both vacancies the hole is located on one oxygen $p$-orbital adjacent to the vacancy. Apical and different basal plane O are considered. The magnetic resonance parameters of the defects are determined using the Gauge Including Projector Augmented Wave (GIPAW) method. The EPR spectra of $V_\mathrm{Ga}^{2-}$ is characterized by a quasi-isotropic superhyperfine (SHF) interaction with one Ga nucleus and for the apical O spin gives a $g$-tensor with maximum oriented along the bond direction from that O to its other Ga neighbor. For $V_\mathrm{Li}^0$ there is a quasi-isotropic SHF interaction with two Ga nuclei and the $g$-tensor maximum is along ${\bf c}$ for the basal plane O spin. Both of these are in agreement with experiment but we predict also the $g$-tensors for the other possible localization of the spins as well as the small hyperfine splittings (as yet not observed) on Li. The energies of formation and transition levels of the corresponding defects provide insight into the conditions required to activate these EPR spectra.

description: The objective of this work was to evaluate the effectiveness of ozone in the control of fungi and the degradation of fumonisins in maize and possible effects on the chemical composition of the product. Two cultivars of hybrid maize (30F53H and AS1581 PRO) were used. Initially, the saturation process of the porous medium with ozone was studied. The incidence of Fusarium verticillioides, Penicillium spp. and Aspergillus flavus; the suitability of ozone to detoxify grains contaminated by fumonisins and possible qualitative changes in the product were evaluated. Ozone was applied at an inlet ozone concentration of 13.5 mg L−1 and flow rate of 1.0 L min−1, in five exposure periods (0, 12, 24, 36, 48 and 60 h). The estimated daily intake of FB by horses from grains subjected to ozonation was obtained. For the hybrid AS1581PRO, the estimated saturation time and concentration were equivalent to 67.34 min and 5.91 mg L−1, respectively. With regard to the hybrid 30F53H, the saturation time and concentration were 41.74 min and 8.72 mg L−1, respectively. Ozone was an effective fungicidal agent. The use of a concentration of 13.5 mg L−1 over a 24 h-treatment led to a reduction of 81.2 and 86.2% in the concentrations of fumonisin B1 and fumonisin B2, respectively. The estimated daily intake of fumonisins was reduced to 17.21 µg kg−1BW per day, corresponding to half of the acceptable daily intake for equines. Ozone did not affect the chemical composition of the grain. Ozone is effective in controlling fungi and as a detoxifying agent in maize contaminated by fumonisins.
Plastic Metabolism in a Garbage Apocalypse

description: We have a plastic waste crisis. Our waste is concealed in bins, taken out to back lanes, buried at the landfill or shipped overseas. We have become increasingly expert at physically distancing ourselves from our waste. Spaces for waste are not for humans. Waste is invisible to us. Plastic Metabolism in a Garbage Apocalypse operates within a fictional, yet plausible, garbage strike. This strike brings the global waste crisis home, registering it at the scale of a household. How do we cope? Our perceptions must shift if we are to escape the constricting infill of waste in our previously pristine domestic realms. We must see waste as a raw material. This project proposes a new system of construction, operating on the existing body of the Vancouver Special, a locally specific and common housing typology. Domestic spatial relationships are re-imagined establishing an intimate relationship between the human body and waste material and processes. Building with waste is imperative. We must see waste as an opportunity, and allow new growth through the reconstitution of waste materials. Using a playful and optimistic perspective, Plastic Metabolism in a Garbage Apocalypse allows the messy and uglier sides of human life to support a productive domestic environment.

description: The ternary uranium compound UCu$_2$Sn with a hexagonal ZrPt$_2$Al-type structure shows a phase transition at 16 K. We reported previously that huge lattice-softening is accompanied by the phase transition, which originates from ferroquadrupolar ordering of the ground state non-Kramers doublet $Γ_5$. A macroscopic strain, which is expected to emerge spontaneously, was not detected by powder X-ray diffraction in the temperature range between 4.2 and 300 K. To search the spontaneous strain, we have carried out thermal expansion measurements on a single-crystalline sample along the $a$, $b$ and $c$ axes using a capacitance technique with the resolution of $10^{-8}$. In the present experiment, we found the spontaneous $e_{xx} - e_{yy}$ strain which couples to the ground state doublet $Γ_5$. The effect of uniaxial pressure along the $a$, $b$ and $c$ axes on the transition temperature is also discussed.

description: The complete tensor structure of the quark--gluon vertex in Landau gauge is determined at two kinematical points (`asymmetric' and `symmetric') from lattice QCD in the quenched approximation. The simulations are carried out at beta=6.0, using a mean-field improved Sheikholeslami-Wohlert fermion action, with two quark masses ~ 60 and 115 MeV. We find substantial deviations from the abelian form at the asymmetric point. The mass dependence is found to be negligible. At the symmetric point, the form factor related to the chromomagnetic moment is determined and found to contribute significantly to the infrared interaction strength.

title: Accelerated crypto currencies: A systematic analysis of Silvio Gesell’s theories and its implementation on local crypto currencies

description: This master’s thesis evaluated the acceptance of crypto currencies, under the impact an existing local Freigeld crypto currency. The intersections of the underlying technology of crypto currencies with a specific part of Silvio Gesell’s Freigeld theory named effective demand, built the basis of a local Freigeld crypto currency scenario. This scenario was then used to evaluate the level of acceptance by comparing the scenario to different crypto currencies. Participants of this study were selected by snowball sampling. The data was gathered by a web browser based self-administered survey.The results showed that the level of acceptance for the local Freigeld crypto currency exceeds the level of every presented crypto currency. Additionally, this study analyzed factors, to explain the cause of the different level of acceptance of the local Freigeld crypto currency. The evaluation showed that the support of the local economy was the only significant impact which caused the increased acceptance of the local Freigeld crypto currency.

description: The elasticity tensor that describes the elastic response of a material to external forces is among the most fundamental properties of materials. The availability of full elasticity tensors for inorganic crystalline compounds, however, is limited due to experimental and computational challenges. Here, we report the materials tensor (MatTen) model for rapid and accurate estimation of the full fourth-rank elasticity tensors of crystals. Based on equivariant graph neural networks, MatTen satisfies the two essential requirements for elasticity tensors: independence of the frame of reference and preservation of material symmetry. Consequently, it provides a unified treatment of elasticity tensors for all seven crystal systems across diverse chemical spaces, without the need to deal with each separately.. MatTen was trained on a dataset of first-principles elasticity tensors garnered by the Materials Project over the past several years (we are releasing the data herein) and has broad applications in predicting the isotropic elastic properties of polycrystalline materials, examining the anisotropic behavior of single crystals, and discovering new materials with exceptional mechanical properties. Using MatTen, we have discovered a hundred new crystals with extremely large maximum directional Young's modulus and eleven polymorphs of elemental cubic metals with unconventional spatial orientation of Young's modulus.
Continual Learning for Domain Adaptation in Chest X-ray Classification

description: Over the last years, Deep Learning has been successfully applied to a broad range of medical applications. Especially in the context of chest X-ray classification, results have been reported which are on par, or even superior to experienced radiologists. Despite this success in controlled experimental environments, it has been noted that the ability of Deep Learning models to generalize to data from a new domain (with potentially different tasks) is often limited. In order to address this challenge, we investigate techniques from the field of Continual Learning (CL) including Joint Training (JT), Elastic Weight Consolidation (EWC) and Learning Without Forgetting (LWF). Using the ChestX-ray14 and the MIMIC-CXR datasets, we demonstrate empirically that these methods provide promising options to improve the performance of Deep Learning models on a target domain and to mitigate effectively catastrophic forgetting for the source domain. To this end, the best overall performance was obtained using JT, while for LWF competitive results could be achieved - even without accessing data from the source domain.

description: We develop a generalized field space geometry for higher-derivative scalar field theories, expressing scattering amplitudes in terms of a covariant geometry on the all-order jet bundle. The incorporation of spacetime and field derivative coordinates solves complications due to higher-order derivatives faced by existing approaches to field space geometry. We identify a jet bundle analog to the field space metric that, besides field redefinitions, exhibits invariance under total derivatives. The invariance consequently extends to its amplitude contributions and the canonical covariant geometry.

Momentum-dependence in the infinitesimal Wilsonian renormalization group
Creators: name: Helias, Moritz
Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Wilson's original formulation of the renormalization group is perturbative in nature. We here present an alternative derivation of the infinitesimal momentum shell RG, akin to the Wegner and Houghton scheme, that is a priori exact. We show that the momentum-dependence of vertices is key to obtain a diagrammatic framework that has the same one-loop structure as the vertex expansion of the Wetterich equation. Momentum dependence leads to a delayed functional differential equation in the cutoff parameter. Approximations are then made at two points: truncation of the vertex expansion and approximating the functional form of the momentum dependence by a momentum-scale expansion. We exemplify the method on the scalar $φ^{4}$-theory, computing analytically the Wilson-Fisher fixed point, its anomalous dimension $η(d)$ and the critical exponent $ν(d)$ non-perturbatively in $d\in[3,4]$ dimensions. The results are in reasonable agreement with the known values, despite the simplicity of the method.
