description: Recent experimental results on the color-suppressed nonleptonic decays B^0 -> D^{(*)0} pi^0 provide evidence for a failure of the naive factorization model and for sizeable relative strong-interaction phases between class-1 and class-2 B -> D^(*) pi decay amplitudes. The allowed regions for the corresponding ratios of (complex) isospin amplitudes and a_2/a_1 parameters are determined. The results are interpreted in the context of QCD factorization for the related class-1 amplitudes in the heavy-quark limit.

description: Power flow through a power system corridor is largely a function of the angle difference between the voltage phasors at two ends. Phase Shifting Transformers (PST) are placed in series with important lines at one end or combined with power transformers, to regulate the voltage angle difference between two ends of a power corridor. Conventional differential relays can not be utilized to protect PST's, as the phase angle shift is not fixed like a standard power transformer with a defined vector group, but it is continuously varying by the position of tap changer. This paper presents a simple solution to compensate the phase angle shift on the input currents of differential protection for any types of transformers including PST. Simulation of a real world disturbance verifies stability of the relay for heavy external faults, and sufficient sensitivity for internal disturbances. By replacing this solution with "vector group compensator" in conventional transformer differential relays, it can be used as well for protection of power transformers with any vector group. In this solution there is no need to transmit the position of on-load tap changer (OLTC) to the differential relay.

description: The first $3^-$ and $4^-$ states of $^{12}$C are studied in the present container model, in which the shift parameter is introduced to break the parity symmetry for projecting out the negative-parity states. Taking the limit as the shift parameter approaches zero and by variational calculations for one-deformed size parameter, the local energy minima are obtained for the $3^-$ and $4^-$ states. It is found that the obtained single THSR (Tohsaki-Horiuchi-Schuck-Röpke) wave functions for $3^-$ and $4^-$ states are 96% and 92% equivalent to the corresponding GCM wave functions, respectively. The calculated intrinsic densities further show that these negative-parity states of three clusters, different with the traditional understanding of rigid triangle structure, are found to have nonlocalized clustering structure in the two-dimensional container picture.

description: In a rapidly changing healthcare environment, we need a robust evidence base to inform effective education and training. This study aimed to examine factors perceived to determine career progression in clinical education research in the UK. Six online focus groups were conducted, with 35 participants from a range of medical, dental, nursing, and allied health professions who identified as aspiring or early career clinical education researchers. Transcripts underwent thematic analysis. Two themes and associated subthemes were constructed to illustrate perceived factors impacting on career development: (1) A cultural challenge from clinical norms. Challenges included differences between the epistemological assumptions of biomedical and clinical research, and the underlying philosophy of education research, which is more closely aligned with the knowledge generation of the social sciences. This led to difficulty communicating the impact of education research to patient care. There were also blurred boundaries between education delivery and research, with the latter lacking a clearly defined group identity. (2) Structures, systems and relationships for career progression. Practical considerations included time and funding (or lack thereof), the opportunity to undertake formal training, networking and role models. This research highlights a number of systemic barriers and facilitators to careers in clinical education research and offers targets of intervention to enable a sustainable academic workforce in clinical education research.

description: We compute electroweak form factors of the nucleon and photon transition form factors of non-strange baryon resonances up to the third resonance region in a model with instanton-induced interaction. The calculation is based on the Bethe-Salpeter equation for three light constituent quarks and is fully relativistic (U. Löring {\it et al.}, Eur. Phys. J. {\bf A10}, 309 (2001)). Static nucleon properties and photon resonance couplings are in good agreement with experiment and the $Q^2$-behaviour of the experimentally known form factors up to large momentum transfer is accounted for.

description: We theoretically investigate the simulation of moving cavities in a superconducting circuit setup. In particular, we consider a recently proposed experimental scenario where the phase of the cavity field is used as a moving clock. By computing the error made when simulating the cavity trajectory with SQUIDs, we identify parameter regimes where the correspondence holds, and where time dilation, as well as corrections due to clock size and particle creation coefficients, are observable. These findings may serve as a guideline when performing experiments on simulation of moving cavities in superconducting circuits.
Parton densities and saturation scale from non-linear evolution in DIS on nuclei

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present the numerical solution of the non-linear evolution equation for DIS on nuclei for $x = 10^{-2} ÷10^{-7}$. We demonstrate that the solution to the non-linear evolution equation is quite different from the Glauber - Mueller formula which was used as the initial condition for the equation. We illustrate the energy profit for performing DIS experiments on nuclei. However, it turns out that the gain is quite modest: $x_{Au} \simeq 5 x_{\rm proton} $ for the same parton density. We find that the saturation scale $Q^2_s \propto A^{1/3}$. For gold the saturation scale $Q_{s,Au} \simeq 1.5 GeV$ at $x= 10^{-3}$. Such a large value leads to considerable contribution of the high density QCD phase to RHIC data and reveals itself in essential damping for both $xG_A$ and $F_{2A}$.

description: Virial relations for the Dirac equation in a central field and their applications to calculations of H-like atoms are considered. It is demonstrated that using these relations allows one to evaluate various average values for a hydrogenlike atom. The corresponding relations for non-diagonal matrix elements provide an effective method for analytical evaluations of infinite sums that occur in calculations based on using the reduced Coulomb-Green function. In particular, this method can be used for calculations of higher-order corrections to the hyperfine splitting and to the g factor in hydrogenlike atoms.

description: Observations of several Fanaroff-Riley (FR) type I sources reveal outflowing bipolar bubbles of hot gas surrounded by a weak forward shock. We consider the possibility that these bubbles were driven by choked relativistic jets which failed to penetrate the ambient intracluster medium (ICM). Using new results on choked jets linking the geometry of the forward shock to the jet properties, we infer robust limits on the radius $R_{ch}$ at which the jet was quenched in 5 well-studied FRI sources, finding typically $R_{ch}\sim 10$ kpc. We further show that, in order to reach this radius in less than the current age of the system, the jet must have been tightly collimated, with the jet head subtending an angle of $θ_h < 2^\circ$. The ambient pressure is not high enough to explain this collimation, suggesting that the jet was collimated by interaction with its own cocoon. Although the choking radius is well-constrained, we find a degeneracy between the initial jet opening angle before collimation, $θ_0$, and the duration of jet activity, $t_b$, with $(t_b/1\rm{Myr})(θ_0/5^\circ)^{-2} \sim 0.1$. We speculate that the working time and/or opening angle of the jet may be important factors contributing to the FR type I/type II morphology in galaxy clusters, with short-lived or wide jets being choked to form bipolar bubbles filled with diffuse radio emission, and longer-lived or narrow jets successfully escaping the cluster core to produce cocoons with radio hotspots.

description: Public transportation is a fundamental infrastructure for the daily mobility in cities. Although its capacity is prepared for the usual demand, congestion may rise when huge crowds concentrate in special events such as massive demonstrations, concerts or sport events. In this work, we study the resilience and recovery of public transportation networks from massive gatherings by means of a stylized model mimicking the mobility of individuals through the multilayer transportation network. We focus on the delays produced by the congestion in the trips of both event participants and of other citizens doing their usual traveling in the background. Our model can be solved analytically for regular lattices showing that the average delay scales with the number of event participants with an exponent equal to the inverse of the lattice dimension. We then switch to real transportation networks of eight worldwide cities, and observe that there is a whole range of exponents depending on where the event is located. These exponents are distributed around 1/2, which indicates that most of the local structure of the network is two dimensional. Yet, some of the exponents are below (above) that value, implying a local dimension higher (lower) than 2 as a consequence of the multimodality and multifractality of transportation networks. In fact, these exponents can be also obtained from the scaling of the capacity with the distance from the event. Overall, our methodology allows to dynamically probe the local dimensionality of a transportation network and identify the most vulnerable spots in cities for the celebration of massive events.

description: We make explicit the statement that Minimal Supersymmetric SU(5) has been excluded by the Super-Kamiokande search for the process $p \to K^{+} \overlineν$. This exclusion is made by first placing limits on the colored Higgs triplet mass, by forcing the gauge couplings to unify. We also show that taking the superpartners of the first two generations to be very heavy in order to avoid flavor changing neutral currents, the so-called ``decoupling'' idea, is insufficient to resurrect the Minimal SUSY SU(5). We comment on various mechanisms to further suppress proton decay in SUSY SU(5). Finally, we address the contributions to proton decay from gauge boson exchange in the Minimal SUSY SU(5) and flipped SU(5) models.

description: The cocktail party problem refers to the famous selective attention problem of how to find out the signal of each individual sources from signals of a number of detectors. In the classical cocktail party problem, the signal of each source is a sequence of data such as the voice from a speaker, and each detector detects signal as a linear combination of all sources. This problem can be solved by a unsupervised machine learning algorithm known as the independent component analysis. In this work we propose a quantum analog of the cocktail party problem. Here each source is a density matrix of a pure state and each detector detects a density matrix as a linear combination of all pure state density matrix. The quantum cocktail party problem is to recover the pure state density matrix from a number observed mixed state density matrices. We propose the physical realization of this problem, and how to solve this problem through either classical Newton's optimization method or by mapping the problem to the ground state of an Ising type of spin Hamiltonian.

description: Medical undergraduates at St George’s, University of London (SGUL) study a weekly clinical case during their clinical science years. Audit of the human stories demonstrated lack of diversity, mono-professionalism, and objectification of some patients. A collaborative partnership with staff, student and patient representation implemented curriculum change, including an inclusive case-writing initiative. We explored whether the reformed written cases supported the development of positive attitudes by sampling perceptions of the cases amongst students. Sixteen semi-structured interviews were conducted (Feb–November 2022) with first year medical students. We applied an interpretative phenomenological analysis approach. Verbatim transcripts were coded and analysed to elucidate themes. Four themes were identified: (i) effective learning, (ii) clinical authenticity, (iii) authentic human stories, and (iv) opportunity for rehearsing the role of a doctor. Students perceived the cases as an effective, contextual learning method, with a high degree of clinical authenticity, allowing mentalisation of doctor attitudes and behaviours in relation to patient-centredness, multidisciplinary team working and diversity. The results suggest the reformed cases created positive attitudinal change amongst students and supported transition to clinical roles. Memorable human stories had the greatest impact. Dynamic, inclusive, and collaborative case writing initiatives which integrate realism, diversity and multi-professionalism may help to foster positive experiences in students undertaking CBL sessions.

description: The first two eigenvalues of the Robin Laplacian are investigated along with their gap and ratio. Conjectures by various authors for arbitrary domains are supported here by new results for rectangular boxes. Results for rectangular domains include that: the square minimizes the first eigenvalue among rectangles under area normalization, when the Robin parameter $α\in \mathbb{R}$ is scaled by perimeter; that the square maximizes the second eigenvalue for a sharp range of $α$-values; that the line segment minimizes the Robin spectral gap under diameter normalization for each $α\in \mathbb{R}$; and the square maximizes the spectral ratio among rectangles when $α>0$. Further, the spectral gap of each rectangle is shown to be an increasing function of the Robin parameter, and the second eigenvalue is concave with respect to $α$. Lastly, the shape of a Robin rectangle can be heard from just its first two frequencies, except in the Neumann case.

description: The role of a marine sanctuary, where commercial fishing might be prohibited, is evaluated in two models; one where net biological growth is deterministic, and the other where net biological growth is stochastic. There is diffusion (migration) between the sanctuary and the fishing grounds based on the ratios of current stock size to carrying capacity in each area. Fishing is managed under a regime of regulated open access. In the deterministic model, it is possible to determine the steady-state equilibrium and to assess its local stability. In the stochastic model a steady state does not exist, but a stable joint distribution for the fish stock on the grounds and in the sanctuary is possible. The creation of a no-fishing marine sanctuary leads to higher population levels on the grounds and in the sanctuary, and appears to reduce the variation of the population in both areas. The higher population levels and reduced variation has an opportunity cost; foregone harvest from the sanctuary.

This state couples strongly to the eta-d channel but its effect on final state interactions in the pn --> eta-d reaction is shown to be rather weak. Fairly large eta-N scattering lengths are allowed by the experimental data.

description: This paper examines the role of energy in long-term growth. The authors estimate a translog production function in capital, labour, and energy, using data on 38 countries from 1965-1990. It is found that separating the countries into two groups, the high growth group and the rest of the world (ROW), yields slope coefficients that are statistically different. Furthermore, there are dramatic differences in the estimated production elasticities, returns to scale, and bias in technical change for the two country groups. Based on the estimated coefficients, the authors approximate the contributions ofthe factors ofproduction in explaining the observed growth in real GDP through a growth accounting exercise. Energy emerges as an important source of growth for both country groups, second only to increases in total factor productivity. In light ofthe negotiations over a Protocol to the Climate Change Convention, the authors estimate the capital and labour requirements for national energy reductions. Finally, the authors use the production function to provide analytical expressions for the elasticity of energy intensity with respect to other factor inputs, and also for autonomous energy efficiency improvements (AEEI). It is found that the deceleration ofthe AEEI in the ROW countries more than offsets the combined acceleration witnessed in Hong Kong, South Korea, and Thailand. -

description: There are many Rankin-Selberg integrals representing Langlands $L$-functions, and it is not apparent what the limits of the Rankin-Selberg method are. The Dimension Equation is an equality satisfied by many such integrals that suggests a priority for further investigations. However there are also Rankin-Selberg integrals that do not satisfy this equation. Here we propose an extension and reformulation of the dimension equation that includes many additional cases. We explain some of these cases, including the new doubling integrals of the authors, Cai and Kaplan. We then show how this same equation can be used to understand theta liftings, and how doubling integrals fit into a lifting framework. We give an example of a new type of lift that is natural from this point of view.

description: We investigate the spectral features of the emission from a superluminal polarization current whose distribution pattern rotates with an angular frequency $ω$ and oscillates with an incommensurate frequency $Ω>ω$. This type of polarization current is found in recent practical machines designed to investigate superluminal emission. Although all of the processes involved are linear, we find that the broadband emission contains frequencies that are higher than $Ω$ by a factor of the order of $(Ω/ω)^2$. This generation of frequencies {\it not} required for the creation of the source stems from mathematically rigorous consequences of the familiar classical expression for the retarded potential. The results suggest practical applications for superluminal polarization currents as broad-band radiofrequency and infrared sources.

description: A seven year comparative study of grid pricing versus average pricing of slaughter cattle was conducted to evaluate carcass quality market signals. The primary objective of the study is to determine if market signals sent through the grid pricing system are encouraging producers to market on a grid and discouraging them to market by the pen. Two secondary objectives investigate: 1) if price risk associated with carcass quality uncertainty affects marketing decisions, and 2) if a change in price risk (volatility) affects producer marketing decisions. An EARCH-In-Mean modeling procedure adjusting carcass quality market signals to encourage marketing on a grid and discourage marketing by the pen. The inclusion of the conditional variance in the empirical model indicates that risk associated with carcass quality uncertainty is a potential barrier to adoption of the grid pricing system by producers was adopted. Empirical results suggest that the grid premium and discount structure is slowly adjusting in a manner that encourages marketing on a grid and discourages marketing by the pen at an average price.
Effects of fungal- and plant-derived non-starch polysaccharides in macrophages

description: The consumption of fungal- and plant-derived non-starch polysaccharides (NSP) has been associated with a reduced risk of cardiovascular diseases and cancer. In addition, to promote physiochemical effects on the gastrointestinal tract and serve as a substrate for the intestinal microbiota to produce short-chain fatty acids, NSP can interact with immune system cells including macrophages, which are crucial for tissue repair, lipid metabolism and host defence against foreign substances and pathogens. However, the effects of NSP in macrophages depends on their structure. Recently, it was showed that the chayote (Sechium edule) and the fungus Pleurotus albidus are promising sources of NSP with potential immunomodulatory effects in macrophages. In this study, it was explored the effects of cooking on the composition of NSP from chayote and evaluated their biological effects in macrophages. Furthermore, it was optimized a method for the extraction of mushroom NSP and characterized the structure and biological effects of NSP from P. albidus in macrophages. Results showed that the NSP from chayote pulp regulate cytokine secretion and phagocytosis by macrophages, and minor changes in composition during cooking influences their effects in macrophages. Furthermore, NSP from chayote induces cholesterol efflux and inhibits the expression of genes required for NLRP3 inflammasome activation in macrophages previously exposed to cholesterol crystals. Then, it was showed that the optimized method for the extraction of NSP from mushroom reduces by up to half the extraction time commonly required. Furthermore, results showed that P. albidus is a source of easily extractable glucans with biological effects in macrophages. Results also suggest that glucans from P. albidus inhibit lipid-induced inflammation and foam-cell formation at distinct levels, with significant effects on NLRP3 inflammasome activation. Taken together, the results suggest that the benefits of chayote NSP are beyond their physical properties on the gastrointestinal tract and that the P. albidus NSP offers potential health benefits that might be of relevance as a functional food ingredient.

description: This paper argues that higher property taxes and uncertainty about post-easement tax levels create a disincentive for landowners to participate in federal conservation easement programs such as the Wetland Reserve Program. This hypothesis is supported by exploratory econometric analyses using state level data from the 1992 Wetlands Reserve Pilot Program. If this conjecture is supported by additional research, then such disincentives should be accounted for in the bid acceptance process of future Federal conservation easement programs, or other policies should be developed to reduce the effects of property tax differentials and posteasement tax uncertainty on enrollment decisions.

description: We present a consistent procedure for the calculation of the one-loop corrections to the charginos and neutralinos by using their on-shell mass matrices. The on-shell gaugino mass parameters M and M', and the Higgsino mass parameter μare defined by the elements of these on-shell mass matrices. The on-shell mass matrices are different by finite one-loop corrections from the tree-level ones given in terms of the on-shell parameters. When the on-shell M and μare determined by the chargino sector, the neutralino masses receive corrections up to 4%. This must be taken into account in precision measurements at future e^+ e^- linear colliders.

description: The charged domain walls in ferroelectric materials exhibit intriguing physical properties. We examine herein the charged-domain-wall structures in Ca$_{3-x}$Sr$_x$Ti$_2$O$_7$ using transmission electron microscopy. When viewed along the [001] axis, the wavy charged domain walls are observed over a wide range ($>$5 $μ$m). In contrast, short charged-domain-wall fragments (from 10 to 200 nm long) occur because they are intercepted and truncated by the conventional 180$^°$ domain walls. These results reveal the unusual charged domain structures in Ca$_{3-x}$Sr$_x$Ti$_2$O$_7$ and will be useful for understanding their formation process.

description: Compared with classical search algorithms, Grover quantum algorithm [ Phys. Rev. Lett., 79, 325(1997)] achieves quadratic speedup and Bruschweiler hybrid quantum algorithm [Phys. Rev. Lett., 85, 4815(2000)] achieves an exponential speedup. In this paper, we report the experimental realization of the Bruschweiler$ algorithm in a 3-qubit NMR ensemble system. The pulse sequences are used for the algorithms and the measurement method used here is improved on that used by Bruschweiler, namely, instead of quantitatively measuring the spin projection of the ancilla bit, we utilize the shape of the ancilla bit spectrum. By simply judging the downwardness or upwardness of the corresponding peaks in an ancilla bit spectrum, the bit value of the marked state can be read out, especially, the geometric nature of this read-out can make the results more robust against errors.

description: We briefly examine the properties of dense plasmas characteristic of the atmospheres of neutron stars and of the interior of massive white dwarfs. These astrophysical bodies are natural laboratories to study respectively the problem of pressure ionization of hydrogen in a strong magnetic field and the crystallization of the quantum one-component-plasma at finite temperature.

description: We consider the single-inclusive minijet cross section in pA at forward rapidity within the Color Glass Condensate model of high energy collisions. We show that the nucleus appears black to the incident quarks except for very large impact parameters. A markedly flatter p_t distribution as compared to QCD in the dilute perturbative limit is predicted for transverse momenta about the saturation scale, which could be as large as Q_s^2 ~ 10 GeV^2 for a gold nucleus boosted to rapidity ~10 (as at the BNL-RHIC).

Infrared dust arcs around the stars: I. effect of the radiation pressure

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In this paper we consider the distribution of the interstellar dust in the vicinity of the star under an influence of the stellar gravitation and radiation pressure. This study is applicable to the stars with relatively weak stellar wind and strong radiation, when the stellar radiation swept out the interstellar dust much further from the star than the position of the bow shock created by an interaction of the stellar and interstellar plasma flows. In this case the number density of dust for a certain dust grains radius can be calculated analytically based on the classical `cold model'. The dust density distribution for the mixture of dust grains with different radii is calculated. We also calculated intensity maps of the thermal infrared emission at 24~$μ$m from dust due to heating by the stellar radiation. It is shown that the obtained maps of the infrared emission extremely depends on the model parameters: material of dust grains, dust size distribution assumed in the interstellar medium, the approach used to calculate the dust temperature. The bright distinct arc at the intensity maps is seen for graphite dust grains and almost disappears for silicates. Absolute values of intensity in the case of graphite are several order of magnitudes larger than for silicates due to more intensive heating of graphite. Possible application of the presented theory is proposed as an algorithm for analysis of the observational images of the infrared arc around the star.

description: The strategy of modern effective field theory is exploited to pin down accurately the flux $S$ factors for the $pp$ and $hep$ processes in the Sun. The technique used is to combine the high accuracy established in few-nucleon systems of the "standard nuclear physics approach" (SNPA) and the systematic power counting of chiral perturbation theory (ChPT) into a consistent effective field theory framework. Using highly accurate wave functions obtained in the SNPA and working to \nlo3 in the chiral counting for the current, we make totally parameter-free and error-controlled predictions for the $pp$ and $hep$ processes in the Sun.

Fetching marked items from an unsorted database in NMR ensemble computing

description: Searching a marked item or several marked items from an unsorted database is a very difficult mathematical problem. Using classical computer, it requires $O(N=2^n)$ steps to find the target. Using a quantum computer, Grover's algorithm uses $O(\sqrt{N=2^n})$ steps. In NMR ensemble computing, Brushweiler's algorithm uses $\log N$ steps. In this Letter, we propose an algorithm that fetches marked items in an unsorted database directly. It requires only a single query. It can find a single marked item or multiple number of items.

description: A total of 15 novel-substituted 3-(benzylsulfanyl)-1H-1,2,4-triazol-5-ylamine and 10 novel-substituted 3-benzylmercapto-1,2,4-triazol derivatives were synthesized based on the natural product phenazine-1-carboxylic acid (PCA). Their structures were confirmed by 1H-NMR, 13C-NMR, HRMS, and X-ray. Most substituted 3-benzylmercapto-1,2,4-triazol derivatives displayed very strong fungicidal activity against one or multiple plant pathogens in vitro and in vivo. Compounds 8b, 8h, and 8i showed a broad spectrum of fungicidal activity. Further field experiments indicated that compounds 8b, 8c, and 8h displayed better efficacy against rice blast (Pyricularia oryzae) than PCA. These data demonstrate that compounds 8b, 8c, and 8h are promising fungicidal candidates, deserving further studies.
