description: The analogy between magnetism and electricity has long been established by Maxwell in the 19th century, in spite of their subtle difference. While magnetic materials display paramagnetism, ferromagnetism, antiferromagnetism, and diamagnetism, only paraelectricity, ferroelectricity, and antiferrolelectricity have been found in dielectric materials. The missing `diaelectricity' may be found if there exists a material that has a dc-polarization opposing the electric field or a negative dielectric susceptibility epsilon'-1, with epsilon' being the real part of the relative dielectric constant. Both of these properties have been observed in nano-particle aggregates under a dc electric bias field at room temperature. A possible collective effect in the nano-particle aggregates is proposed to account for the observation. `Diaelectricity' implies overscreening by polarization to the external charges. Materials with a negative static epsilon' are expected to provide attraction to similar charges and unusual scattering to electromagnetic waves with possible profound implications for high temperature superconductivity and communication.

Trade policy votes and antitrust : do consumers matter?

description: In analyzing the potential exercise of monopoly power in domestic markets, both the academic literature and U.S. antitrust authorities have acknowledged the disciplining role of competition from abroad. In this paper, we explore the extent to which this view seems to reveal itself in recent U.S. Congressional votes taken during the 108th Congress (2003-04) on four free trade agreements (FTAs). To the extent that antitrust and trade liberalization are both viewed as pro-consumer in nature, we would expect to see a positive relationship between antitrust enforcement in their legislative district and Congressional votes in support of new FTAs. We do find evidence supporting a positive relationship between state-level antitrust enforcement and support for FTAs.

description: Free-space channels provide the possibility of establishing continuous-variable quantum key distribution (CV-QKD) in global communication networks. However, the fluctuating nature of transmissivity in these channels introduces an extra noise which reduces the achievable secret key rate. We consider two classical post-processing strategies, post-selection of high-transmissivity data and data clusterization, to reduce the fluctuation-induced noise of the channel. We undertake the first investigation of such strategies utilising a composable security proof in a realistic finite-size regime against both collective and individual attacks. We also present an efficient parameter estimation approach to estimate the effective Gaussian parameters over the post-selected data or the clustered data. Although the composable finite-size effects become more significant with the post-selection and clusterization both reducing the size of the data, our results show that these strategies are still able to enhance the finite-size key rate against both individual and collective attacks with a remarkable improvement against collective attacks--even moving the protocol from an insecure regime to a secure regime under certain conditions.

description: {\em Quantum Fourier analysis} is a new subject that combines an algebraic Fourier transform (pictorial in the case of subfactor theory) with analytic estimates. This provides interesting tools to investigate phenomena such as quantum symmetry. We establish bounds on the quantum Fourier transform $\FS$, as a map between suitably defined $L^{p}$ spaces, leading to a new uncertainty principle for relative entropy. We cite several applications of the quantum Fourier analysis in subfactor theory, in category theory, and in quantum information. We suggest a new topological inequality, and we outline several open problems.

The main contribution to the MRFM signal is associated with a part of the resonance slice near the surface of the sample. The regular (approximately exponential) decay of the MRFM signal is followed by the non-dissipating random signal. The Fourier spectrum of the random signal has a characteristic peak which can be used for the identification of the signal.

The cumulative infected data were fitted with various growth models (e.g. Logistic equation, Weibull equation and Hill equation) and obtained the power index of top ten highly infected countries. The newly infected data were fitted with Gaussian distribution with the peak at ~40 days for the countries whose infection curves are seem to be saturated. The similarity in growth kinetics of infected people of different countries provides first-hand guidelines to take proper precautions to minimize human damage.

title: Amyloid Beta Transport and Effects on Permeability in a Human Brain Endothelial Cell Line
Creators: name: Tai, Leon M.
Publisher: name: The Open University
Year: 2009

description: The clearance of neurotoxic amyloid beta (Aβ) from the brain represents a novel therapeutic target for Alzheimer's disease (AD). The ability of two blood-brain barrier (BBB) drug transporters, P-glycoprotein (P-gp) and the breast cancer resistance protein (BCRP), to transport Aβ was investigated using a human brain endothelial cell (BEC) line, hCMEC/D3. P-gp expression by hCMEC/D3 cells was stable over a high passage number, polarised on the apical membrane, consistent with the blood side in vivo, and comparable, albeit slightly reduced, to primary isolated human BECs. The P-gp inhibitors tariquidar and vinblastine prevented the efflux of rhodamine 123 from hCMEC/D3 cells, indicative of functional P-gp expression. hCMEC/D3 cells therefore constituted a suitable model to investigate P-gp substrate interactions in vitro. P-gp, and to a lesser extent BCRP, inhibition, increased the net influx and decreased the efflux of 0.1 nM 125I Aβ 1-40 in hCMEC/D3 cells. Both P-gp and BCRP inhibition increased the apical-to-basolateral but not the basolateral-to-apical permeability of hCMEC/D3 cells to 125I Aβ 1-40. This data is consistent with P-gp and BCRP, acting in vivo to prevent blood-borne Aβ peptides entering the brain but not to clear Aβ load from the brain.

Vascular dysfunction is emerging as a key pathological hallmark in AD, including increased BBB permeability. The effect of Aβ on the permeability of hCMEC/D3 cells was therefore investigated. Aβ 1-40 induced a marked increase in hCMEC/D3 cell permeability to the paracellular tracer 70 kDa FITC-dextran. Increased permeability was associated with a specific decrease in the tight junction protein occludin, but not claudin-5 or ZO-1, both at the protein and mRNA levels. JNK and p38MAPK inhibition prevented Aβ 1-40-mediated occludin down-regulation and increased paracellular permeability of hCMEC/D3 cells. Our findings suggest that the JNK and p38MAPK pathways might represent attractive therapeutic targets for preventing vascular dysfunction in AD.

description: Accurate description of the excess charge in water cluster anions is challenging for standard semi-local and (global) hybrid density functional approximations (DFAs). Using the recent unitary invariant implementation of the Perdew-Zunger self-interaction correction (SIC) method using Fermi-Löwdin orbitals, we assess the effect of self-interaction error on the vertical detachment energies of water clusters anions with the local spin density approximation (LSDA), Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation, and the strongly constrained and appropriately normed (SCAN) meta-GGA functionals. Our results show that for the relative energies of isomers with respect to reference CCSD(T) values, the uncorrected SCAN functional has the smallest deviation of 21 meV, better than that for the MP2 method. The performance of SIC-SCAN is comparable to that of MP2 and is better than SIC-LSDA and SIC-PBE, but it reverses the ordering of the two lowest isomers for water hexamer anions. Removing self interaction error (SIE) corrects the tendency of LSDA, PBE, and SCAN to over-bind the extra electron. The vertical detachment energies (VDEs) of water cluster anions, obtained from the total energy differences of corresponding anion and neutral clusters, are significantly improved by removing self-interaction and are better than the hybrid B3LYP functional, but fall short of MP2 accuracy. Removing SIE results in substantial improvement in the position of the eigenvalue of the extra electron. The negative of the highest occupied eigenvalue after SIC provides an excellent approximation to the VDE, especially for SIC-PBE where the mean absolute error with respect to CCSD(T) is only 17 meV, the best among all approximations compared in this work.

Russian Price Reform Eliminates Shortages, Alters Meat Consumption

Food Consumption/Nutrition/Food Safety

description: Setting the stage for the evolution toward a free-market economy from central planning has entailed both positive and difficult adjustments in Russiathe largest former Soviet republic. Food shortages in state stores, once universal, are now sporadic. Overall food consumption has dropped-particularly consumption of livestock products, which had been maintained at artificially high levels before the reforms. These changes resulted from partial price deregulation (which eliminated shortages and shifted relative prices) and restrictive wage policy (which eroded real incomes). These trends will likely continue in 1994, if prices remain deregulated and if the level of producer subsidies does not increase substantially.

description: We present results for the three-loop universal anomalous dimension of Wilson twist-2 operators in the N=4 Supersymmetric Yang-Mills model. These results are obtained by extracting the most complicated contributions from the three loop non-singlet anomalous dimensions in QCD which were calculated recently. Their singularities at j=1 agree with the predictions obtained from the BFKL equation for N=4 SYM in the next-to-leading order. The asymptotics of universal anomalous dimension at large j is in an agreement with the expectations based on an interpolation between weak and strong coupling regimes in the framework of the AdS/CFT correspondence.

Demand and Price Analysis

description: The collapse of Communism in Poland, Hungary, and thenCzechoslovakia over the last several years has set the stage for the difficult beginning of free-market economies. In 1990, these countries started to wean consumers away from the government subsidies that had kept food prices artificially low for many years. After the subsidies stopped-and price controls were lifted-food prices soared at both producer and consumer levels. In quick succession, inflation rose and purchasing power dropped, reducing consumer demand-especially for meat and dairy products. Three years later, however, food prices in these countries appear to have stabilized, despite some continuing contraction in demand. Following the reforms, income has fallen, but a broad range of new goods have appeared on the market, fundamentally changing the range of choices available to consumers.

Food Consumption/Nutrition/Food Safety

description: Food expenditures rose 2.3 percent in 1992 to $601 billion, with food at home up 1.3 percent and food away from home rising 3.5 percent (table 1). This growth was lower than for any other major category of personal consumption expenditures, as is typical (table 2). With the Nation gradually climbing out of recession in 1992 and with very small price increases for food at home, food expenditures adjusted for inflation rose 0.7 percent (0.1 percent at home and 1.5 percent away from home}--less than population growth. In other words, food spending per person at constant prices declined 0.4 percent in 1992. Price rises were modest-the smallest in 25 years-due to ample supplies, and were much less than for most other products and services. Vigorous competition among sellers of food-both for use at home and away-helped restrain price increases

description: For certain industrial control applications an explicit function capturing the nontrivial trade-off between competing objectives in closed loop performance is not available. In such scenarios it is common practice to use the human innate ability to implicitly learn such a relationship and manually tune the corresponding controller to achieve the desirable closed loop performance. This approach has its deficiencies because of individual variations due to experience levels and preferences in the absence of an explicit calibration metric. Moreover, as the complexity of the underlying system and/or the controller increase, in the effort to achieve better performance, so does the tuning time and the associated tuning cost. To reduce the overall tuning cost, a tuning framework is proposed herein, whereby a supervised machine learning is used to extract the human-learned cost function and an optimization algorithm that can efficiently deal with a large number of variables, is used for optimizing the extracted cost function. Given the interest in the implementation across many industrial domains and the associated high degree of freedom present in the corresponding tuning process, a Model Predictive Controller applied to air path control in a diesel engine is tuned for the purpose of demonstrating the potential of the framework.

description: The sustainability of the U.S. water supply is fraught with challenges and inefficiencies. This paper addresses various facets of this problem with three primary policy alternatives. First, we propose that the federal government implement governance and pricing changes that facilitate widespread conservation. Second, we propose that consumers receive tax credits and information to curb household water use. Finally, we propose new financing mechanisms to encourage infrastructure upgrades and adoption of new irrigation technologies to reduce water consumption in both urban and agricultural areas. These three alternatives would be most beneficial if implemented together in a comprehensive solution—changes to the governance and pricing structure of water in the first alternative would multiply the impacts of second and third alternative.

First model includes two sorts of spins, s= 1/2 and s= 1, and the second model comprises only s=1/2 legs coupled by a "triangular" rung exchange. The antiferromagnetic (AF) rung coupling destroys the long-range order and eventually makes the systems equivalent to the AF s=1/2 Heisenberg chain. We investigate the situation by different methods in weak and strong rung coupling limits. Particularly we compare the spin-wave theory and the bosonization method in the weak coupling regime of the second model. We analyze the spectra and correlations, and discuss the order parameter of these ladder systems.

Electrical transport measurements show evidence of the desired twist between the graphene layers fabricated using our technique. Statistics of the number of successfully twisted stacks made using our method is compared with h-BN assisted tear-and-stack method. Also, our method can be used for twisted stack fabrication of materials that are few nanometers thick. Finally, we demonstrate the versatility of the tapered fibre scalped for other shaping related applications for sensitive 2D materials.

Explaining National Environmental Performance : What Do We Know and What Should We Learn?

description: Although local, regional, and global institutions are critical to environmental policy success, national governments still arguably are the linchpin. This article examines and assesses the research on national environmental performance in four categories: economic growth and income; regime type, in terms of the level of democracy; the institutional characteristics of regime type; and institutional capacity. The research suggests that economic development and democratic governance are generally associated with environmental policy success, although not for all problems and in all settings. Development creates the conditions for encouraging and enabling societies to respond to environmental problems, while also creating an additional set of challenges for environmental quality. The effects of the institutional characteristics of democratic regimes are unclear, although there is evidence that the new and complex demands of environmental sustainability are managed more successfully within systems having an ability to integrate environmental, economic, and political/social choices. The existing research provides a valuable foundation for additional efforts to understand and explain national environmental performance.

description: In this paper we study the problem of how resilient networks are to node faults. Specifically, we investigate the question of how many faults a network can sustain so that it still contains a large (i.e. linear-sized) connected component that still has approximately the same expansion as the original fault-free network. For this we apply a pruning technique which culls away parts of the faulty network which have poor expansion. This technique can be applied to both adversarial faults and to random faults. For adversarial faults we prove that for every network with expansion alpha, a large connected component with basically the same expansion as the original network exists for up to a constant times alpha n faults. This result is tight in the sense that every graph G of size n and uniform expansion alpha(.), i.e. G has an expansion of alpha(n) and every subgraph G' of size m of G has an expansion of O(alpha(m)), can be broken into sublinear components with omega(alpha(n) n) faults. For random faults we observe that the situation is significantly different, because in this case the expansion of a graph only gives a very weak bound on its resilience to random faults. More specifically, there are networks of uniform expansion O(sqrt{n}) that are resilient against a constant fault probability but there are also networks of uniform expansion Omega(1/log n) that are not resilient against a O(1/log n) fault probability. Thus, a different parameter is needed. For this we introduce the span of a graph which allows us to determine the maximum fault probability in a much better way than the expansion can. We use the span to show the first known results for the effect of random faults on the expansion of d-dimensional meshes.

title: Evaluation of population genetic structure and horizontal gene transfer for the human pathogen Burkholderia pseudomallei
Creators: name: Tumapa, Sarinna
Publisher: name: The Open University
Year: 2008

description: Burkholderia pseudomallei is a soil-dwelling saprophyte and the cause of melioidosis. Multilocus sequence typing (MLST) of 266 Thai B. pseudomallei isolates (83 soil and 183 invasive) defined 123 sequence types (STs). Invasive isolates were over-represented in the 10 largest clones, and there was a significant difference in the classification index between environmental and disease isolates, confirming that genotypes were not distributed randomly between the two samples. MLST profiles for 158 predominantly invasive isolates from northern Australia contained a similar number of STs (96) as the Thai invasive isolates, but no ST was found in both populations. This analysis revealed strong genetic differentiation on the basis of geographical isolation, and a significant differentiation on the basis of virulence potential.

The presence and distribution of five genomic islands described for B. pseudomallei K96243 was investigated in natural populations. In silico analysis of 10 B. pseudomallei genome sequences demonstrated variable presence of these regions, together with evidence for micro-evolutionary changes that generates GI diversity. Their presence was assessed in environmental (83) and invasive (103) B. pseudomallei isolates using PCR. Positivity ranged from 12% for a prophage-like island (GI 9), to 76% for a metabolic island (GI 16). The presence of each of the five GIs did not differ between environmental and disease-associated isolates. There was no reproducible association between the individual or cumulative presence of five GIs and clinical features in 103 patients with melioidosis.

Burkholderia thailandensis is a non-pathogenic soil saprophyte which is highly related to B. pseudomallei. MLST of a collection of B. thailandensis isolates demonstrated two clusters. One cluster contained three isolates (one each from France, the U.S. and Cambodia), and the second larger cluster contained isolates from Thailand, Vietnam and Laos. eBURST analysis indicated that the larger cluster formed a single clonal complex, while all three strains of the small cluster were singletons.
The Ground State of the Sine-Gordon Soliton

description: At one loop, we provide an explicit formula for the ground state of the one-soliton sector in the Sine-Gordon theory. The state is given in the basis of eigenstates of the field operator, or equivalently as a Schrodinger wave functional. The formula readily generalizes to other solitons in other models and as an example we also provide the ground state of the kink in the (1+1)-dimensional $ϕ^4$ double well.

description: Evaluation of sustainability of agricultural farms is among the most topical academic and practical – farm, business and policies forwarded issues. Despite that there are practically no studies on overall, economic, social, ecological, etc. sustainability of Bulgaria farms during European Union (EU) Common Agricultural Policy (CAP) implementation. This article tries to fill the gap and presents results of a first large-scale study on integral, governance, economic, social, and environmental sustainability of market oriented farms in Bulgaria in general and for holdings of different juridical type, size, specialization and location. Initially, a holistic framework for assessing sustainability of Bulgarian farms is outlined, including a system of appropriate for the specific conditions of Bulgarian agriculture system of principles, criteria, indicators, and reference values for evaluating individual aspects and the integral sustainability of farming enterprises. Next, an assessment of made of the overall, governance, economic, social, and environmental sustainability of Bulgarian farms in general and holdings of different juridical type, size, specialization, ecological and geographical location. Finally, implications for further research and practices in sustainability assessment are withdrawn.
Flyback-Based Multiple Output dc-dc Converter with Independent Voltage Regulation

Publisher: name: arXiv

Subjects: subject: Systems and Control (eess.SY)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: This paper proposes a new single input multiple output power supply by integrating a flyback converter and several buck converters. The flyback converter works as the main regulator, and the buck converters provide series voltage compensation with the aim of tight regulation. A time multiplexing switching scheme is proposed to deliver multiple output voltage levels via a two winding transformer and to eliminate the cross regulation between output channels. This configuration reduces the size of flyback transformer and filter capacitors, and consequently improves the overall form factor. A detailed steady state analysis is conducted on the circuit to obtain the design criteria. A three output channel power supply is designed and the effectiveness of the proposed configuration is validated via simulation with a MATLAB/Simscape model. Simulation results also demonstrate satisfactory transient response to load changes.

HYBRID VERSION OF LINGUISTICS WITH THE HUMANITARIAN DISCIPLINES.  THE PECULIARITIES OF ETHNOLINGUISTICS IN LINGUISTICS
Creators: name: Isroilova, Dilnavoz
name: Rakhimova, Nodira
Publisher: name: Zenodo
Year: 2024

description: This article explores the integration of ethnolinguistics within linguistics, specifically within the hybrid version that combines linguistics with the humanities. Ethnolinguistics is an interdisciplinary area of study that explores the relationship between language and culture. It dates back to the early 20th century, when linguists and anthropologists recognized the value of studying the relationship between language and culture. The German linguist Wilhelm von Humboldt is known for having provided a model for ethnolinguistics, based on his work on the relationship between language and thought and his focus on the study of language in a cultural context.
