description: Optimal placement of distributed generation (DG) units in a radial distribution network can reduce the system losses, improve the voltage profile of the network and thereby maximize the techno-economic benefits. The present problem considers various indices, namely the cost index, voltage deviation index and line flow capacity index, with several equality and inequality constraints, to analyse the techno-economic benefits. An opposition-based tuned-chaotic differential evolution (OTCDE) technique is proposed to avoid premature convergence. This technique uses an opposition-based scheme for initialization and logistic mapping to generate chaotic sequences within the specified range for the mutation factor, because wrong parameter selection may lead to premature convergence and even stagnation. The proposed algorithm has been applied on IEEE 33-bus, 69-bus and 118-bus radial distribution systems to verify its effectiveness. By several statistical analyses, it is observed that the proposed technique outperforms other newly proposed metaheuristic techniques.

description: Fluctuations of the Chern-Simons gauge field in the composite Fermi liquid description of the half-filled Landau level are pair breaking in all angular momentum channels. For short-range electron-electron interactions these fluctuations are sufficiently strong to drive any T=0 pairing transition first order. For Coulomb interactions these fluctuations are weaker and a continuous transition is possible.

description: We study the electronic states of the anisotropic triangular lattice Hubbard model at half filling, which is a simple effective model for the organic superconducting $κ$-BEDT-TTF compounds. We treat the effect of the Coulomb interaction by the fluctuation exchange (FLEX) method, and obtain the phase diagram of this model for various sets of parameters. It is shown that the d-wave superconductivity is realized in the wide region of the phase diagram, next to the antiferromagnetic states. The obtained phase diagram explains the characters of the experimental results very well.

Initial condition of a thick loop cosmic string and linear perturbations

subject: FOS: Physical sciences

description: The initial data of the gravitational field produced by a loop thick string is considered. We show that a thick loop is not a geodesic on the initial hypersurface, while a loop conical singularity is. This suggests that there is the ``{\it critical thickness}'' of a string, at which the linear perturbation theory with a flat space background fails to describe the gravity of a loop cosmic string. Using the above initial data, we also show that the linear perturbation around flat space is plausible if the string thickness is larger than $\sim5\times10^{-3}a$, where $a$ is the curvature radius of the loop.

description: A search for nu_mu -> nu_e oscillations has been conducted at the Los Alamos Meson Physics Facility using nu_mu from pi^+ decay in flight. An excess in the number of beam-related events from the C(nu_e,e^-)X inclusive reaction is observed. The excess is too large to be explained by normal nu_e contamination in the beam at a confidence level greater than 99%. If interpreted as an oscillation signal, the observed oscillation probability of (2.6 +- 1.0 +- 0.5) x 10^{-3} is consistent with the previously reported nu_mu_bar -> nu_e_bar oscillation evidence from LSND.

Three classes of completely regular semigroups, namely semigroups for which $\kerσ$ is a cryptogroup, semigroups for which $\kerν$ is a cryptogroup and semigroups for which $κ$ is over rectangular bands, are studied. $((ω_t)_k)_t$, $((\mathcal{D}_t)_k)_t$ and $((ω_k)_t)_k$ are found to be the least congruences on $S$ such that the quotient semigroups are semigroups for which $\kerσ$ is a cryptogroup, $\kerν$ is a cryptogroup and $κ$ is over rectangular bands, respectively. The results obtained present a response to three problems in Petrich and Reilly's textbook \textquoteleft\textquoteleft Completely Regular Semigroups\textquoteright\textquoteright.

description: Polyvinyl alcohol (PVA)/carboxymethyl cellulose (CMC) hydrogels were fabricated with varying concentrations of CMC. The hydrogels underwent cross-linking using non-toxic and biocompatible citric acid (CA) in combination with the freeze-thaw technique. FTIR analysis confirmed the hydrogels' chemical structures, while SEM characterization determined their pore diameters and porosity ratios. Hydrogels with diverse porosities exhibited suitable pore diameters for skin cells. Moreover, the hydrogels demonstrated a high swelling capacity, and the augmentation of CMC content resulted in increased water retention capacity. Their water vapor transmission, combined with their swelling properties, highlights their potential as suitable materials for use in wound dressings. These biopolymer-based hydrogels show promise for various applications, including wound dressings and biomimetic artificial skin, effectively replicating the properties of the epidermis and dermis.

description: We present ab-initio local density FLAPW calculations on non-reactive N-terminated [001] ordered GaN/Ag and GaN/Au interfaces and compare the results (such as metal induced gap states and Schottky barrier heights) with those obtained for GaN/Al, in order to understand the dependence of the relevant electronic properties on the deposited metal. Our results show that the density of gap states is appreciable only in the first semiconductor layer close to the interface. The decay length of the gap states in the semiconductor side is about 2.0 $\pm$ 0.1 Å$\:$ and is independent of the deposited metal, therefore being to a good extent a bulk property of GaN. Our calculated values of the Schottky barrier heights are $Φ_{B_p}(GaN/Ag)$ = 0.87 eV and $Φ_{B_p}(GaN/Au)$ = 1.08 eV; both values are smaller than the GaN/Al value ($Φ_{B_p}(GaN/Al)$ = 1.51 eV) and this quite large spread of values excludes the possibility of a Fermi level pinning within the GaN band gap. Because of the low screening in GaN, the potential barrier at the junction is strongly affected by the structural arrangement of the first metal layer at the interface. This leads to quite large variations of the Schottky barrier height as a function of the metal, in contrast with the behavior of GaAs/metal interfaces.

description: In the context of complex scalar field coupled to Einstein gravity theory, we present a novel family of solutions of Kerr black holes with excited-state scalar hair inspired by the work of Herdeiro and Radu in [Phys.\ Rev.\ Lett.\ {\bf 112}, 221101 (2014)], which can be regarded as numerical solutions of rotating compact objects with excited scalar hair, including boson stars and black holes. In contrast to Kerr black holes with ground state scalar hair, we find that the first-excited Kerr black holes with scalar hair have two types of nodes, including radial $n_r=1$ and angular $n_θ=1$ nodes. Moreover, in the case of radial nodes the curves of the mass versus the frequency form nontrivial loops, and in the case of angular nodes the curves can be divided into two kinds: closed and open loops. We also study the dependence of the horizon area on angular momentum and Hawking temperature.

description: O número especial dedicado ao tema: “SOCIOBIODIVERSIDADE E POLÍTICAS PUBLICAS. Diálogos interculturais, articulações interdisciplinares e diversidade de saberes”, decorre na sequência de diversos projetos de intercâmbio e Cooperação Internacional dedicados a compreender as dinâmicas socioambientais em territórios diversificados onde se manifestam desafios biopolíticos e sociais complexos e multidimensionais. Deste modo, a elaboração deste número especial tem como principal objetivo analisar questões relevantes da atualidade no domínio da sociobiodiversidade e políticas públicas, explorando as interligações entre os processos socioeconómicos e políticos e a participação dos múltiplos atores sociais em diferentes níveis de actuação - global, regional e local. A abordagem dos desafios socioambientais, especialmente em contextos de desigualdade social acentuada resultante de políticas públicas desajustadas, pode ser significativamente fortalecida pela construção de novas perspetivas políticas e conceptuais. Para tal, é essencial promover diálogos interculturais, processos de articulação interdisciplinar e a valorização da diversidade de saberes. O desenvolvimento de metodologias participativas assentes no envolvimento das comunidades tradicionais e povos originários com os seus interesses e ações, pode desempenhar um papel crucial na preservação da sociodiversidade e na afirmação da territorialidade com a pluralidade de culturas que a povoam. Ao mesmo tempo, estas estratégias contribuem para estimular a sustentabilidade ambiental, reforçando a interconexão entre a sociedade e a natureza na construção de futuros mais equitativos e sustentáveis.

description: A pesca em águas continentais deixou há já alguns anos de ser apenas praticada com fins alimentares e as sociedades mais contemporâneas reconhecem que esta atividade possui um valor lúdico-desportivo crescente, cuja dinâmica é capaz de gerar importantes recursos sociais e económicos para o desenvolvimento de algumas regiões do nosso país, sobretudo as do interior, menos desenvolvidas. A evolução tecnológica dos utensílios de pesca (lúdica, desportiva, profissional e tradicional) têm por seu turno colocado no mercado materiais mais sofisticados e seletivos para captura de determinadas espécies piscícolas. Existem várias técnicas para captura de carpa como a pesca à boia, pesca ao fundo, pesca ao lançado ligeiro e pesca á mosca. Uma das modalidades, carp fishing, é um dos exemplos de pesca lúdico-desportiva que merece esse mesmo enquadramento. Constitui assim uma das inúmeras disciplinas de pesca em água docecujo objetivo fundamental é pescar preferencialmente exemplares troféu de carpas, Cyprinus sp.. Esta modalidade de pesca distingue-se das demais, pelos meios e processos de pesca específicos, usando, sempre que necessário, equipamentos específicos que asseguram a devolução do peixe nas melhores condições físicas e de bem-estar, minimizando qualquer tipo de desconforto ou sofrimento (prática obrigatória da pesca sem morte ou de “captura e solta”).

description: Steady state dynamics of clustering, long range order, and inelastic collapse are experimentally observed in vertically shaken granular monolayers. At large vibration amplitudes, particle correlations show only short range order like equilibrium 2D hard sphere gases. Lowering the amplitude "cools" the system, resulting in a dramatic increase in correlations leading either to clustering or an ordered state. Further cooling forms a collapse: a condensate of motionless balls co-existing with a less dense gas. Measured velocity distributions are non-Gaussian, showing nearly exponential tails.

description: A maioria da população mundial vive em áreas urbanas, causando competição pelo espaço e pelos recursos, entre a cidade e o espaço rural e natural envolvente. Há compromissos relacionados com a biodiversidade, para aplicação a nível nacional e local, tais como a Convenção sobre a Diversidade Biológica, Objetivos do Desenvolvimento Sustentável, Estratégia da Biodiversidade da UE para 2030 ou Agenda21Local. No contexto urbano, as ações de cariz local são particularmente relevantes pela proximidade dos órgãos de decisão ao território e pelo impacto mais rapidamente sentido.


Neste trabalho, procura-se contribuir para os estudos sobre avaliação de biodiversidade urbana, ainda pouco frequentes na Europa, estudando a biodiversidade urbana de Chaves, cidade de pequena dimensão numa região tradicionalmente agrícola do Norte de Portugal.


Partimos da metodologia para a aplicação do Índice de Biodiversidade Urbana (CBI), selecionando e estimando o valor de vários dos seus indicadores, recorrendo a dados oficiais, bibliografia e projetos das especialidades que contribuem diretamente para a sua aferição. Caracterizou-se também a perceção da comunidade utilizadora sobre a biodiversidade urbana, através de um inquérito, analisando a correspondência entre a perceção social da biodiversidade urbana e os valores obtidos para os indicadores do CBI.


Foi possível calcular a maioria dos indicadores do CBI, observando-se que nesta fase os indicadores menos pontuados ou não calculados pertencem sobretudo à categoria da governança e gestão da biodiversidade urbana. Da consulta pública realizada, ainda que não representativa da população local, verifica-se um bom entendimento do conceito de biodiversidade, da importância dos espaços verdes urbanos e da capacidade de identificação das oportunidades e ameaças à biodiversidade urbana de Chaves.

In this approach calculations are performed without the use of angular momentum decomposition and instead rely directly on the 3D degrees of freedom of the nucleons. In this paper, for the first time, 3D results for $^{3}$He bound state with the inclusion of the screened Coulomb potential are compared to $^{3}$H calculations. Additionally, using these results, matrix elements of simple current operators related to the description of beta decay of the triton are given. All computations are carried out using the first generation of NNLO two nucleon (2N) and 3N forces from the Bochum - Bonn group.

description: Radial velocity (RV) measurements are used to search for planets orbiting late-type main-sequence stars and confirm the transiting planets. The most advanced spectrometers are approaching a precision of $\sim 10$ cm/s that implies the need to identify and correct for all possible sources of RV oscillations intrinsic to the star down to this level and possibly beyond. The recent discovery of global-scale equatorial Rossby waves in the Sun, also called r modes, prompted us to investigate their possible signature in stellar RV measurements. R modes are toroidal modes of oscillation whose restoring force is the Coriolis force and propagate in the retrograde direction in a frame that corotates with the star. The solar r modes with azimuthal orders $3 \leq m \lesssim 15$ were identified unambiguously because of their dispersion relation and their long e-folding lifetimes of hundreds of days. Here we simulate the RV oscillations produced by sectoral r modes with $2 \leq m \leq 5$ assuming a stellar rotation period of 25.54 days and a maximum amplitude of the surface velocity of each mode of 2 m/s. This amplitude is representative of the solar measurements, except for the $m=2$ mode which has not yet been observed. Sectoral r modes with azimuthal orders $m=2$ and $3$ would produce RV oscillations with amplitudes of 76.4 and 19.6 cm/s and periods of 19.16 and 10.22 days, respectively, for a star with an inclination of the rotation axis $i=60^{\circ}$. Therefore, they may produce rather sharp peaks in the Fourier spectrum of the radial velocity time series that could lead to spurious planetary detections. Sectoral r~modes may represent a source of confusion in the case of slowly rotating inactive stars that are preferential targets for RV planet search. The main limitation of the present investigation is the lack of observational constraint on the amplitude of the $m=2$ mode on the Sun.

Warfarin versus DOACs in the prevention of thromboembolic stroke in patients with Afib.
Creators: name: Szabon, Allen
Publisher: name: The Journal of Canada’s Physician Assistants
Year: 2021

description: ABSTRACT Preventing thromboembolic (TE) events “such as stroke” is an important part of managing patients with non-valvular atrial fibrillation (Afib). Over the last 50 years, oral anticoagulant treatment with the Vitamin K Antagonist (VKA) warfarin has played a crucial role in the secondary prevention of stroke for patients with Afib. Direct oral anticoagulant (DOACs), and their dominance over warfarin has arrived for treatment of Afib in the context of stroke prevention and research indicates DOACs are, for the most part, superior to warfarin in the secondary prevention of stroke in patients with non-valvular Afib. But what does the evidence tell us about risk versus benefits? The purpose of this review of literature is to conduct a systematic review of the advantages and disadvantages of DOACs, namely dabigatran, rivaroxaban, apixaban and edoxaban compared with warfarin in patients with (non-valvular) Afib. In general, this review demonstrates the advantages of DOACs compared with warfarin including, DOACs are associated with lower rates of life-threatening and intracranial bleeding, DOACs have a rapid onset with peak effect within a few hours, they have predictable dose responses, thus eliminating the need for routine monitoring; and they have few, if any, important food or drug interactions, thus simplifying management. The findings of this systematic literature review suggest that in the secondary prevention of stroke in patients with non-valvular Afib, DOACs, demonstrate a significant advantage and enhanced safety profile over warfarin in reducing the risk of thromboembolic stroke compared with warfarin. As such, DOACs should be considered first-line therapy in the secondary prevention of stroke in patients with non-valvular Afib.

description: A link between the spin fluctuation and the "fermiology" is explored for the single-band Hubbard model within the fluctuation exchange (FLEX) approximation. We show that the experimentally observed peak position of the spin structure in the high T_C cuprates can be understood from the model that reproduces the experimentally observed Fermi surface. In particular, both the variation of the incommensurability of the peak in the spin structure and the evolution of the Fermi surface with hole doping in La_{2-x}Sr_xCuO_4 may be understood with a second nearest neighbor hopping decreasing with hole doping.

description: Adaptations for feeding underwater were crucial to the success of pinnipeds (seals, sea lions, and walruses) in their transition from terrestrial to aquatic habitats. Extant phocids (true seals) use multiple feeding strategies—biting, filter, and suction feeding—to capture and consume prey, and each strategy is associated with cranial, mandibular, and dental adaptations. However, little is known about feeding strategies in stem pinnipeds. The objectives of this study were to investigate feeding strategies used by some extinct pinnipeds based on cranial and mandibular morphologies and use this framework to examine the evolution of phocid feeding strategies. Three-dimensional cranial and mandibular landmark data were collected from 249 extant and fossil pinnipeds. Principal component analysis and canonical variate analysis were performed to describe the major axes of variation and compare overlap of fossil and extant taxa in morphospace. Stem pinnipeds had morphologies associated with biting and filter feeding. Several fossil taxa were most similar to extant biters, suggesting that biting was a common and important feeding strategy for early phocids. One fossil taxon, Homiphoca capensis, was potentially a filter feeder, because it consistently overlapped with extant filter feeders in cranial morphospace. No fossil taxa had morphological adaptations for suction feeding, indicating that suction feeding is a more derived strategy in phocids. Extant phocids and their ancestors have cranial and mandibular adaptations for multiple feeding strategies, which allowed these animals to move into diverse aquatic niches and likely contributed to their successful transition from terrestrial to aquatic ecosystems.

description: The phase behavior of binary fluid mixtures of hard hyperspheres in four and five dimensions is investigated. Spinodal instability is found by using a recent and accurate prescription for the equation of state of the mixture that requires the equation of state of the single component fluid as input. The role played by the dimensionality on the possible metastability of the demixing transition with respect to a fluid-solid transition is discussed. The binodal curves in the pressure--chemical potential representation are seen to lie on a common line, independent of the size ratio

description: Introduction: A postoperative ileus (POI) is a common complication in patients following abdominal surgery which slows patient recovery and increases postoperative morbidity, length of hospital stay, resource use and healthcare costs. Although many interventions have been hypothesized to play a role in the prevention and management of POI, including chewing gum, coffee, and early enteral feeding, current guidelines regarding best clinical practice are lacking. Objective: The efficacy and safety of various dietary interventions used in the reduction of POI, to aid in providing evidence-based recommendations for future Canadian guidelines on this topic. Chewing gum, coffee, and early enteral feeding was examined. Methods: This literature review used the PubMed database. The primary outcomes measured were the effectiveness of each intervention in lowering the incidence of an ileus as well as their overall safety. Results: Four of eight studies identified positive benefits from the addition of chewing gum on bowel recovery. Three primary studies identified that coffee is beneficial in reducing time to first bowel movement. Three of four studies showed that early enteral feeding significantly improves gastrointestinal motility. All studies reviewed agreed that their respective interventional measures are safe and are not associated with an increase in postoperative complications. Conclusion: Although none of the interventions reviewed show complete consensus regarding their ability to reduce POI, there is an agreement that these measures are safe, well-tolerated, and not related to any major adverse effects. Therefore, chewing gum, coffee, and early enteral feeding are all postoperative measures that patients can be encouraged to adopt. The exact combination of these methods which should be included in the guidelines is unknown and requires further studies to examine the additional benefits provided by using more than one intervention.

description: The two-orbital Kondo model with classical Jahn-Teller phonons is studied using Monte Carlo techniques. The observed phase diagram is rich, and includes a novel regime of phase separation induced by the orbital degrees of freedom. Experimental consequences of our results are discussed. In addition, the optical conductivity $σ(ω)$ of the model is presented. It is shown to have several similarities with experimental measurements for manganites.

description: The production of heavy quarkonium as QQbar bound-states in hadron-hadron collisions is considered within the framework of a space-time description, combining parton-cascade evolution with a coalescence model for bound-state formation. The `hard' production of the initial QQbar, directly or via gluon fragmentation and including both color-singlet and color-octet contributions, is calculated from the PQCD cross-sections. The subsequent development of the QQbar system is described within a space-time generalization of the DGLAP parton-evolution formalism in position- and momentum-space. The actual formation of the bound-states is accomplished through overlap of the QQbar pair and a spectrum of quarkonium wave-functions. This coalescence can only occur after sufficent gluon radiation reduces the QQbar relative velocity to a value commensurate with the non-relativistic kinematics of these bound systems. The presence of gluon participants in the cascade then is both necessary and leads to the natural inclusion of both color-singlet and color-octet mechanisms. The application of this approach to pp (ppbar) collisions from sqrt(s)= 30 GeV - 14 TeV reveals very decent agreement with available data from ISR and Tevatron - without the necessity of introducing fit parameters. Moreover, production probabilities are calculated for a complete spectrum of charmonium and bottonium states, with the relative significance compared to open charm (bottom) production. An analysis of the space-time development is carried through which sheds light on the relevance of gluon radiation and color-structure, suggesting a correponding experimental investigation.

description: Metals are highly opaque, yet we show that densely packed arrays of metallic nanoparticles can be more transparent to infrared radiation than dielectrics such as germanium, even for arrays that are over 75% metal by volume. Despite strong interactions between the metallic particles, these arrays form effective dielectrics that are virtually dispersion-free, making possible the design of optical components that are achromatic over ultra-broadband ranges of wavelengths from a few microns up to millimetres or more. Furthermore, the local refractive indices may be tuned by altering the size, shape, and spacing of the nanoparticles, allowing the design of gradient-index lenses that guide and focus light on the microscale. The electric field is also strongly concentrated in the gaps between the metallic nanoparticles, and the simultaneous focusing and squeezing of the electric field produces strong `doubly-enhanced' hotspots which could boost measurements made using infrared spectroscopy and other non-linear processes over a broad range of frequencies, with minimal heat production.
Mean Motion Resonances With Nearby Moons: An Unlikely Origin For The Gaps Observed In The Ring Around The Exoplanet J1407b

description: With the use of numerical models, we investigate whether Mean Motion Resonances (MMR) with nearby moons to the J1407b ring system were the cause of the observed 0.0267AU wide gap located at 0.4AU. Only one location of a moon at 0.63AU (corresponding to a 2:1 MMR) was found to form a gap at 0.4AU over short time periods of less than 100yr. However, the proximity of a low mass moon (0.08 Earth masses) caused significant scattering of the outer ring edge at 0.6AU, along with the formation of an additional gap at the 3:2 MMR (0.485 AU), which is not consistent with observations. Further models with moons located at MMR 3:1, 4:1, 7:3 and 5:3 failed to form gaps at 0.4AU for time periods less than 100yr. Instead, gaps were formed in the ring at 3:2 and 2:1 MMR which resulted in gaps at radial locations between 0.44-0.56AU. Additionally, gaps also take longer than one orbital period of J1407b about the primary to form. Given that J1407b is on a highly eccentric orbit and is thought to strongly perturb the ring at apocentre it appears unlikely that gaps form due to MMR with nearby moons as opposed to embedded moons. Including an appropriate total mass of the ring equal to Earth a dampening effect was witnessed on the gap formation process, causing an increase in the time required to open a gap due to MMR. Therefore, we conclude the observed gap at 0.4 AU is unlikely to be caused by MMR with nearby moons.

description: Ground state energies for plaquette and dimer order in the $J_1-J_2$ square-lattice spin-half Heisenberg model are compared using series expansion methods. We find that these energies are remarkably close to each other at intermediate values of $J_2/J_1$, where the model is believed to have a quantum disordered ground state. They join smoothly with those obtained from the Ising expansions for the 2-sublattice Néel-state at $J_2/J_1 \approx 0.4$, suggesting a second order transition from a Néel state to a quantum disordered state, whereas they cross the energy for the 4-sublattice ordered state at $J_2/J_1 \approx 0.6$ at a large angle, implying a first order transition to the 4-sublattice magnetic state. The strongest evidence that the plaquette phase is not realized in this model comes from the analysis of the series for the singlet and triplet excitation spectra, which suggest an instability in the plaquette phase. Thus, our study supports the recent work of Kotov et al, which presents a strong picture for columnar dimer order in this model. We also discuss the striped nature of spin correlations in this phase, with substantial resonance all along columns of dimers.
