Bound State and Order Parameter Mixing Effect by Nonmagnetic Impurity Scattering in Two-band Superconductors

description: We investigate nonmagnetic impurity effects in two-band superconductors, focusing on the effects of interband scatterings. Within the Born approximation, it is known that interband scatterings mix order parameters in the two bands. In particular, only one averaged energy gap appears in the excitation spectrum in the dirty limit. [G. Gusman: J. Phys. Chem. Solids {\bf 28} (1967) 2327.] In this paper, we take into account the interband scattering within the $t$-matrix approximation beyond the Born approximation in the previous work. We show that, although the interband scattering is responsible for the mixing effect, this effect becomes weak when the interband scattering becomes very strong. In the strong interband scattering limit, a two-gap structure corresponding to two order parameters recovers in the superconducting density of states. We also show that a bound state appears around a nonmagnetic impurity depending on the phase of interband scattering potential.

description: Finding the strength of an edge in a network has always been a big demand. In the context of social networks, it allows to estimate the relationship strength between users. The best-known method to compute edge strength is the Neighbourhood Overlap. It computes the ratio of common neighbours to all neighbours of an edge terminal nodes. This method has been initially proposed for unweighted networks and later extended for weighted ones. These two versions of the method are not mathematically equivalent: In fact, an unweighted network is commonly considered as weighted with all edge weights equal to one. Using both existent versions of Neighbourhood Overlap on such network produce completely different values. In this paper, we tackle this problem and propose a new generalization for Neighbourhood Overlap that works equally for unweighted and weighted networks. Experiment performed on networks with various parameters showed similar performance of our measure to the existing measures.

description: We have studied how parton distributions based on the inclusion of nonlinear scale evolution and constraints from HERA data affect charm production in $pp$ collisions at center-of-mass energies of 5.5, 8.8 and 14 TeV. We find that, while the resulting enhancement can be substantial, it is very sensitive to the charm quark mass and the scale entering the parton densities and the strong coupling constant.

description: We analyze the set ${\cal A}_N^Q$ of mixed unitary channels represented in the Weyl basis and accessible by a Lindblad semigroup acting on an $N$-level quantum system. General necessary and sufficient conditions for a mixed Weyl quantum channel of an arbitrary dimension to be accessible by a semigroup are established. The set ${\cal A}_N^Q$ is shown to be log--convex and star-shaped with respect to the completely depolarizing channel. A decoherence supermap acting in the space of Lindblad operators transforms them into the space of Kolmogorov generators of classical semigroups. We show that for mixed Weyl channels the hyper-decoherence commutes with the dynamics, so that decohering a quantum accessible channel we obtain a bistochastic matrix form the set ${\cal A}_N^C$ of classical maps accessible by a semigroup. Focusing on $3$-level systems we investigate the geometry of the sets of quantum accessible maps, its classical counterpart and the support of their spectra. We demonstrate that the set ${\cal A}_3^Q$ is not included in the set ${\cal U}^Q_3$ of quantum unistochastic channels, although an analogous relation holds for $N=2$. The set of transition matrices obtained by hyper-decoherence of unistochastic channels of order $N\ge 3$ is shown to be larger than the set of unistochastic matrices of this order, and yields a motivation to introduce the larger sets of $k$-unistochastic matrices.

description: Using an entirely new data source, this article presents evidence that significant variation exists in how much different presidential administrations use private White House polls. Federal Election Commission (FEC) disclosure records reveal the amount of money that presidents since Jimmy Carter paid (through their respective party organizations) to the designated White House pollsters. These financial figures, in turn, roughly correlate with the estimated number of polls commissioned for the White House, as determined through archival research and information provided by the pollsters themselves. Two patterns emerge: some presidents poll heavily from the start of their administrations (Ronald Reagan and Bill Clinton); others poll only lightly during the first 3 years in office (Jimmy Carter and George Bush). These findings reinforce scholarly assessments of Reagan and Clinton as pursuing a permanent campaign approach to leadership, whereas Carter and Bush lacked much interest in public relations techniques. Our evidence suggests a need for a refinement of the institutionalization concept as found in the academic literature on White House polling. We agree that all modern presidents inherit sophisticated tools for understanding public opinion, but we demonstrate that they do not use these tools with equal attention or regularity. Put differently, a polling capability has been institutionalized within the White house, but substantial variation still exists in how much a given administration uses that capability.

Private Polls and Presidential Policymaking : Reagan as a Facilitator of Change

description: Did the Reagan administration disregard majority will when crafting its policy initiatives? Did it cater to a narrow partisan constituency instead? The answers to these questions will help with an assessment of Jacobs and Shapiro’s (2000b) hypothesis that presidents since the late 1970s have used private White House survey research as a tool to manipulate or assuage centrist public opinion while meeting the policy demands of their partisan core supporters, resulting in a decline in presidential responsiveness to majority will. Using the actual surveys administered by Richard Wirthlin (Reagan’s pollster) between 1981 and 1983, this article will demonstrate the level of consistency between majority opinion on 129 policy issues and Reagan’s behavior through 1984, and it will explore the conditions under which the president was more or less likely to respond to public preferences. The data reveal that the Reagan administration was constrained by the popular will in predicable ways: if the policy issues were about domestic concerns, highly popular, and visible in the media, then the administration acted in line with public preferences more than 70 percent of the time. Further, Reagan and his advisers were selective in responding to party activists: they championed issues drawn from their conservative ideological agenda that fit with the current tide in public opinion, while sidestepping other issues dear to party activists that encountered strong majority resistance. While I do not contest Jacobs and Shapiro’s (2000b) important observation that presidents often use survey research to “craft talk” in an attempt to channel the public debate, the evidence here highlights how the president nonetheless remains constrained by the popular will, at least on domestic issues.

Hallucination and naive realism
Creators: name: Kovakovich, Karson
Publisher: name: No Publisher Supplied
Year: 2022

description: A perennial challenge for naive realism is the argument from hallucination which relies on some version of the claim that veridical perception and hallucination share some deep similarity. Naive realists account for the character of veridical experience in terms of certain special relations to parts of the external world. But some hallucinations seem to share the same character despite those relations being absent. In recent literature, Michael Martin has sharpened this worry about hallucination by presenting the so-called ‘screening off problem’. The idea is that the causal factors that explain the character of experience in the case of hallucination are also present in the case of veridical perception, and that such factors should be adequate to explaining the character of experience in both cases (since things look the same to a subject as between a case of veridical perception and its hallucinatory counterpart). Since, according to the argument, such factors do not involve the naive realist’s special relations to the external world, such relations are explanatorily screened off.In this dissertation, I carefully examine the range of naive realist theories on the market and attempt to extract some core theses and thereby unify presentations that differ in terminology. As important ground clearing, I articulate along the way the various relevant kinds of perceptual experience and the crucial ideology of phenomenal character. Next, I examine what is often regarded as the most powerful case for naive realism, namely its intuitive appeal and argue that the supposed intuitive advantages of naive realism over its main competitor, intentionalism, are overstated.In evaluating the screening off problem, I argue, its standard presentation is quite problematic. I go on to present a new variant of the screening off problem, one based on narrowness rather than causation, that is crisper and more challenging than the original version. I present a menu of escape routes for the naive realist. The good news for the naive realist is that there are quite a few possible escape routes. The bad news is that they are all unappetizing.Finally, I turn to William Fish’s naive realism, which constitutes the most prominent recent defense of that approach. Two novel arguments are presented against Fish’s account of hallucination. One of those arguments, which receives extended attention, turns on the HP principle: that hallucinability entails possibility. First, I show that Fish’s view is committed to the HP principle. Next, I work through several different potential counterexamples and use them as case studies to test the HP principle. I ultimately argue against the HP principle and thereby demonstrate the failure of Fish’s positive account of hallucination. I also argue that Fish imposes indefensible connections between the character of experience and rational agents.
Development of a sustained bupivacaine and dexamethasone nanoparticle co-therapy for the treatment of osteoarthritis
Creators: name: Patel, Mayur
Publisher: name: No Publisher Supplied
Year: 2022

description: Osteoarthritis (OA) is the most common chronic condition of the joints, characterized by pain, swelling, and deterioration of cartilage. OA does not have a cure, and currently, all treatments target symptoms such as pain or inflammation but at the doses given, result in adverse side effects which can promote cartilage degeneration. Our research works to develop a controlled dual-modal drug delivery therapy that can manage pain directly and address the underlying cause with anti-inflammatory treatments to prevent cartilage degeneration caused by high doses. Bupivacaine (BUP), a local anesthetic, can manage pain directly and dexamethasone (DEX), a glucocorticoid, offers anti-inflammatory properties and potential chondroprotective attributes. A key obstacle of BUP and DEX is that at high concentrations, both drugs prevent the formation of new cartilage; but, at low concentrations, they can provide pain relief and anti-inflammatory properties for only a short duration. To resolve this issue, we are using nanoparticles made of Poly(lactic-co-glycolic acid) (PLGA), a biodegradable polymer, to prolong the release of BUP and DEX for at least 30 days. Using the nanoparticles diffusion profiles, loading capacity, and optimal dose for our target cell types we tested our dual-modal nanoparticle therapy on chondrocytes, macrophages, and in a co-culture. We found that the nanoparticle co-therapy retained cell viability in all conditions and reduced inflammation more than either DEX nanoparticle (DexNP) or BUP nanoparticle (BupNP) therapy alone.

description: An immersed interface-lattice Boltzmann method (II-LBM) is developed for modelling fluid-structure systems. The key element of this approach is the determination of the jump conditions that are satisfied by the distribution functions within the framework of the lattice Boltzmann method when forces are imposed along a surface immersed in an incompressible fluid. In this initial II-LBM, the discontinuity related to the normal portion of the interfacial force is sharply resolved by imposing the relevant jump conditions using an approach that is analogous to imposing the corresponding pressure jump condition in the incompressible Navier-Stokes equations. We show that the jump conditions for the distribution functions are the same in both single-relaxation-time and multi-relaxation-time LBM formulations. Tangential forces are treated using the immersed boundary-lattice Boltzmann method (IB-LBM). The performance of the II-LBM method is compared to both the direct forcing IB-LBM for rigid-body fluid-structure interaction, and the classical IB-LBM for elastic interfaces. Higher order accuracy is observed with the II-LBM as compared to the IB-LBM for selected benchmark problems. Because the jump conditions of the distribution function also satisfy the continuity of the velocity field across the interface, the error in the velocity field is much smaller for the II-LBM than the IB-LBM. The II-LBM is also demonstrated to provide superior volume conservation when simulating flexible boundaries.

description: The realization that supersymmetry (SUSY), if softly broken at the weak scale, can stabilize the Higgs sector led many authors to explore the role it may play in particle physics. It was widely anticipated that superpartners would reveal themselves once the TeV scale was probed in high energy collisions. Experiments at the LHC have not yet revealed any sign for direct production of superpartners, or for any other physics beyond the Standard Model. This has led to some authors to question whether weak scale SUSY has a role to play in stabilizing the Higgs sector. We show that SUSY models with just the minimal particle content may well be consistent with data and simultaneously serve to stabilize the Higgs sector, if model parameters generally regarded as independent turn out to be appropriately correlated. In our view, it would be premature to ignore this possibility, given that we do not understand the underlying mechanism of SUSY breaking. We advocate using the electroweak scale quantity, $\delew$, to determine whether a given SUSY spectrum might arise from a theory with low fine-tuning, even when the parameters correlations mentioned above are present. We find that all such models contain light higgsinos and that this leads to the possibility of new strategies for searching for SUSY. We discuss phenomenological implications of these models for SUSY searches at the LHC and its luminosity and energy upgrades, as well as at future electron-positron colliders. We conclude that natural SUSY, defined as no worse than a part in 30 fine-tuning, will not escape detection at a $pp$ collider operating at 27~TeV and an integrated luminosity of 15~ab$^{-1}$, or at an electron-positron collider with a centre-of-mass energy of 600~GeV.

description: Recent observational results show that very low mass stars and brown dwarfs are able to host close-in rocky planets. Low-mass stars are the most abundant stars in the Galaxy and the formation efficiency of their planetary systems is relevant in the computation of a global probability of finding Earth-like planets inside habitable zones. Tidal forces and relativistic effects are relevant in the latest dynamical evolution of planets around low-mass stars and their effect on the planetary formation efficiency still needs to be addressed. Our goal is to evaluate the impact of tidal forces and relativistic effects on the formation of rocky planets around a star close to the substellar mass limit, in terms of the resulting planetary architectures and its distribution according to the corresponding evolving habitable zone. Thus, we performed a set of $N$-body simulations spanning the first 100~Myr of the evolution of two systems composed respectively by 224 embryos with a total mass 0.25M$_\oplus$ and 74 embryos with a total mass 3 M$_\oplus$ around a central object of 0.08~M$_\odot$. For these two scenarios, we compared the planetary architectures that result from simulations that are purely gravitational with those from simulations that include the early contraction and spin-up of the central object, the distortions and dissipation tidal terms and general relativistic effects. We found that including these effects allows the formation and survival of a close-in population located in the habitable zone of the system. This means that both effects are relevant during the formation of rocky planets and their early evolution around stars close to the substellar mass limit, in particular when low-mass planetary embryos are involved.

description: Background: Candida species are usually opportunistic organisms that cause acute to chronic infections when conditions in the host are favorable. Accurate identification of Candida species is an essential pre-requisite for improved therapeutic strategy. Identification of Candida species by conventional methods is time-consuming with low sensitivity, yet molecular approaches have provided an alternative way for early diagnosis of invasive candidiasis. Denaturing gradient gel electrophoresis (DGGE) and temporal temperature gradient gel electrophoresis (TTGE) are polymerase chain reaction (PCR)-based approaches that are used for studying the community structure of microorganisms. By using these methods, simultaneous identification of multiple yeast species will be possible and reliable results will be obtained quickly.
Objectives: In this study, DGGE and TTGE methods were set up and evaluated for the detection of different Candida species, and their results were compared.
Materials and Methods: Five different Candida species were cultured on potato dextrose agar medium for 24 hours. Next, total DNA was extracted by the phenol-chloroform method. Two sets of primers, ITS3-GC/ITS4 and NL1-GC/LS2 were applied to amplify the desired regions. The amplified fragments were then used to analyze DGGE and TTGE profiles.
Results: The results showed that NL1-GC/LS2 primer set could yield species-specific amplicons, which were well distinguished and allowed better species discrimination than that generated by the ITS3-GC/ITS4 primer set, in both DGGE and TTGE profiles. All five Candida species were discriminated by DGGE and TTGE using the NL1-GC/LS2 primer set.
Conclusions: Comparison of DGGE and TTGE profiles obtained from NL1-GC/LS2 amplicons exhibited the same patterns. Although both DGGE and TTGE techniques are capable of detecting Candida species, TTGE is recommended because of easier performance and lower costs.

description: Coronal Mass Ejections (CMEs) may have major importance for planetary and stellar evolution. Stellar CME parameters, such as mass and velocity, have yet not been determined statistically. So far only a handful of stellar CMEs has been detected mainly on dMe stars using spectroscopic observations. We therefore aim for a statistical determination of CMEs of solar-like stars by using spectroscopic data from the ESO phase 3 and Polarbase archives. To identify stellar CMEs we use the Doppler signal in optical spectral lines being a signature of erupting filaments which are closely correlated to CMEs. We investigate more than 3700 hours of on-source time of in total 425 dF-dK stars. We find no signatures of CMEs and only few flares. To explain this low level of activity we derive upper limits for the non detections of CMEs and compare those with empirically modelled CME rates. To explain the low number of detected flares we adapt a flare power law derived from EUV data to the Hα regime, yielding more realistic results for Hα observations. In addition we examine the detectability of flares from the stars by extracting Sun-as-a-star Hα light curves. The extrapolated maximum numbers of observable CMEs are below the observationally determined upper limits, which indicates that the on-source times were mostly too short to detect stellar CMEs in Hα. We conclude that these non detections are related to observational biases in conjunction with a low level of activity of the investigated dF-dK stars.

Stimulation of sodium pump restores membrane potential to neurons excited by glutamate in zebrafish distal retina

Publisher: name: American University

description: Glutamate either depolarizes or hyperpolarizes retinal neurons. Those are the initial and primary effects. Using a voltage probe (oxonol, DiBaC4 (5)) to study dissociated zebrafish retinal neurons, we find a secondary, longer-term effect: a post-excitatory restoration of membrane potential, termed after-hyperpolarization (AHP). AHP occurs only in neurons that are depolarized by glutamate and typically peaks about 5 min after glutamate application. AHP is seen in dissociated horizontal cells (HCs) and hyperpolarizing, or OFF type, bipolar cells (HBCs). These cells commonly respond with only an AHP component. AHP never occurs in depolarizing, or ON type, bipolar cells (DBCs), which are cell types hyperpolarized by glutamate. AHP is blocked by 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX). It is evoked by kainate, AMPA and the AMPA-selective agonist (S)-5-fluorowillardiine, but not by NMDA, d-aspartate, the kainate-selective agonist SYM 2081 or by dl-2-amino-4-phosphonobutyric acid (dl-AP4). Cells with exclusively AHP responses are tonically depolarized. Resting potentials can be restored by nifedipine, suggesting a tonic, depolarizing action of L-type Ca2+ channels. However AHP is not blocked by nifedipine and is insensitive to [Cl−]o. AHP is blocked by Li+o substitution for Na+o and by ouabain. A mechanism is proposed in which Na+ entering through ionotropic AMPA channels stimulates Na+,K+-ATPase, which, by electrogenic action, restores membrane potential, generating the AHP response. Patterns of ATPase immunoreactivity support localization in the outer plexiform layer (OPL) as cone pedicles, HCs and BCs were positively labelled. Labelling was weaker in the inner plexiform layer (IPL) than in nuclear layers, though two IPL bands of immunoreactive BC terminals could be discerned, one in sublamina a and the other in sublamina b. Persistent stimulation of distal retina by photoreceptor glutamate may induce increased expression and activity of Na+,K+-ATPase, with a consequent impact on distal glutamate responses.

It is shown, both theoretically and experimentally, how to obtain the Reut's loading by exploiting the contact with friction of a rigid blade against a freely-rotating cylindrical constraint, which moves axially at constant speed, an action recalling that of a bow's hair on a violin string. With this experimental set-up, flutter and divergence instabilities, as well as the detrimental effect of viscosity on critical loads, are documented indisputably, thus bringing an end to a long debate. This result opens a new research area, with perspective applications to mechanical actuators, high-precision cutting tools, or energy harvesting devices.

description: When ranking big data observations such as colleges in the United States, diverse consumers reveal heterogeneous preferences. The objective of this paper is to sort out a linear ordering for these observations and to recommend strategies to improve their relative positions in the ranking. A properly sorted solution could help consumers make the right choices, and governments make wise policy decisions. Previous researchers have applied exogenous weighting or multivariate regression approaches to sort big data objects, ignoring their variety and variability. By recognizing the diversity and heterogeneity among both the observations and the consumers, we instead apply endogenous weighting to these contradictory revealed preferences. The outcome is a consistent steady-state solution to the counterbalance equilibrium within these contradictions. The solution takes into consideration the spillover effects of multiple-step interactions among the observations. When information from data is efficiently revealed in preferences, the revealed preferences greatly reduce the volume of the required data in the sorting process. The employed approach can be applied in many other areas, such as sports team ranking, academic journal ranking, voting, and real effective exchange rates.

description: By the qualitative and quantitative analysis method, we analyze the driving forces of arable land resource change in Jieshou City and find that the arable land resource change in Jieshou City arises mainly from social and economic driving forces. Based on the social and economic indicator data about arable land resource in Jieshou City, we use principal component analysis to establish evaluation index system, and analyze the driving forces of dynamic arable land resource change in Jieshou City during 2006-2015. It is concluded that Jieshou's arable land change is mainly affected by economic and social factors.

description: Glutamate either depolarizes or hyperpolarizes retinal neurons. Those are the initial and primary effects. Using a voltage probe (oxonol, DiBaC4 (5)) to study dissociated zebrafish retinal neurons, we find a secondary, longer-term effect: a post-excitatory restoration of membrane potential, termed after-hyperpolarization (AHP). AHP occurs only in neurons that are depolarized by glutamate and typically peaks about 5 min after glutamate application. AHP is seen in dissociated horizontal cells (HCs) and hyperpolarizing, or OFF type, bipolar cells (HBCs). These cells commonly respond with only an AHP component. AHP never occurs in depolarizing, or ON type, bipolar cells (DBCs), which are cell types hyperpolarized by glutamate. AHP is blocked by 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX). It is evoked by kainate, AMPA and the AMPA-selective agonist (S)-5-fluorowillardiine, but not by NMDA, d-aspartate, the kainate-selective agonist SYM 2081 or by dl-2-amino-4-phosphonobutyric acid (dl-AP4). Cells with exclusively AHP responses are tonically depolarized. Resting potentials can be restored by nifedipine, suggesting a tonic, depolarizing action of L-type Ca2+ channels. However AHP is not blocked by nifedipine and is insensitive to [Cl−]o. AHP is blocked by Li+o substitution for Na+o and by ouabain. A mechanism is proposed in which Na+ entering through ionotropic AMPA channels stimulates Na+,K+-ATPase, which, by electrogenic action, restores membrane potential, generating the AHP response. Patterns of ATPase immunoreactivity support localization in the outer plexiform layer (OPL) as cone pedicles, HCs and BCs were positively labelled. Labelling was weaker in the inner plexiform layer (IPL) than in nuclear layers, though two IPL bands of immunoreactive BC terminals could be discerned, one in sublamina a and the other in sublamina b. Persistent stimulation of distal retina by photoreceptor glutamate may induce increased expression and activity of Na+,K+-ATPase, with a consequent impact on distal glutamate responses.

description: Larval weakfish Cynoscion regalis (Bloch & Schneider) were examined to determine the influence of dietary conditioning on prey selection Experiments were conducted with larvae in each of 4 age classes (8, 11, 14 and 17 d posthatching) Larvae were given a monospecific diet of either large rotifers small rotifers, or brine shrimp nauplii for 5 d prior to an experiment Larvae were then given a choice between the familiar prey and one of the other prey types In separate experimental trials, the conditioned prey was administered in 3 different proportions (10. 25 or 40%) of the total ration Larvae consumed both prey types in all trials, but analysis of gut contents often showed a significant deviation from expected ratios of the 2 prey In expenments with the 2 size classes of rotifer, all ages of larvae chose the familiar prey In the large rotifer/brine shrimp experiments, larvae 11 and 14 d posthatching could be conditioned to large rotifers however, larvae 17 d posthatching always chose brine shrimp, even when initially conditioned to rotifers In comparisons of small rotifers and brine shrimp larvae never showed a preference for rotifers These results indicate that effects of dietary conditioning on prey selection vary with larval age and relative prey size.

description: Joint, or simultaneous, measurements of non-commuting observables are possible within quantum mechanics, if one accepts an increase in the variances of the jointly measured observables. In this paper, we discuss joint measurements of a spin 1/2 particle along any two directions. Starting from an operational locality principle, it is shown how to obtain a bound on how sharp the joint measurement can be. We give a direct interpretation of this bound in terms of an uncertainty relation.

description: The library is a place that can be used to find several journal references, and books to borrow or just read in the library. With the increasing number of libraries in the manual system, it is becoming inefficient nowadays. By using information technology such as the internet, the need for information delivery and retrieval can be done quickly, because the internet is a very wide network and is an effective and efficient way for information delivery and search. The development of the World Wide Web (WWW) is very rapid with the emergence of various websites with interactive web pages. WWW provides an excellent graphical display, besides the technological concepts it uses provide convenience and efficient speed.
