description: We study the trace anomaly of a Weyl fermion in an abelian gauge background. Although the presence of the chiral anomaly implies a breakdown of gauge invariance, we find that the trace anomaly can be cast in a gauge invariant form. In particular, we find that it does not contain any odd-parity contribution proportional to the Chern-Pontryagin density. The latter would be allowed by the consistency conditions. We perform our calculations using Pauli-Villars regularization and heat kernel methods. The issue is analogous to the one recently discussed in the literature about a conjectured contribution of an odd-parity term to the trace anomaly of a Weyl fermion in curved backgrounds.

The Radial Extent and Warp of the Ionized Galactic Disk. II. A Likelihood Analysis of Radio-Wave Scattering Toward the Anticenter

description: We use radio-wave scattering data to constrain the distribution of ionized gas in the outer Galaxy. Like previous models, our model for the H II disk includes parameters for the radial scale length and scale height of the H II, but we allow the H II disk to warp and flare. Our model also includes the Perseus arm. We use a likelihood analysis on 11 extragalactic sources and 7 pulsars. Scattering in the Perseus arm is no more than 60% of the level contributed by spiral arms in the inner Galaxy, equivalent to a 1 GHz scattering diameter of 1.5 mas. Our analysis favors an unwarped, nonflaring disk with a 1 kpc scale height, though this may reflect the non-uniform and coarse coverage provided by the available data. The lack of a warp indicates that VLBI observations near 1 GHz with an orbiting station having baseline lengths of a few Earth diameters will not be affected by interstellar scattering at Galactic latitudes |b| ~ 15 degrees. The radial scale length is 15--20 kpc, but the data cannot distinguish between a gradual decrease in the electron density and a truncated distribution. We favor a truncated one, because we associate the scattering with massive star formation, which is also truncated near 20 kpc. The distribution of electron density turbulence decreases more rapidly with Galactocentric distance than does the hydrogen distribution. Alternate ionizing and turbulent agents---the intergalactic ionizing flux and satellite galaxies passing through the disk---do not contribute significantly to scattering. We cannot exclude the possibility that a largely ionized, but quiescent disk extends to >~ 100 kpc, similar to that for some Ly-alpha absorbers.

description: We consider the tensor product of the completely depolarising channel on $d\times d$ matrices with the map of Schur multiplication by a $k \times k$ correlation matrix and characterise, via matrix theory methods, when such a map is a mixed (random) unitary channel. When $d=1$, this recovers a result of O'Meara and Pereira, and for larger $d$ is equivalent to a result of Haagerup and Musat that was originally obtained via the theory of factorisation through von Neumann algebras. We obtain a bound on the distance between a given correlation matrix for which this tensor product is nearly mixed unitary and a correlation matrix for which such a map is exactly mixed unitary. This bound allows us to give an elementary proof of another result of Haagerup and Musat about the closure of such correlation matrices without appealing to the theory of von Neumann algebras.

description: Climate change and variability are major threats to people’s livelihoods in Somaliland, as they depend on agriculture and livestock and have a low adaptive capacity. This review aimed to assess the impacts of climate variability on livelihoods, identify gaps, and provide ways to enhance adaptation and resilience in Somaliland. It was based on secondary data from relevant sources such as journal articles, books, chapters, and reports from national and international organizations. This review revealed that extreme climate events, such as droughts and floods, have significantly impacted livelihoods in Somaliland by causing crop failure, livestock loss, food insecurity, water scarcity, and population displacement. The literature lacks sufficient data and analysis on the vulnerability and adaptation of different livelihood groups and sectors in Somaliland. The country’s institutions and policies have not adequately addressed the issues of climate risk reduction and community resilience. This review provides ways to enhance a country’s climate and livelihood by informing policymakers, planners, and other stakeholders to intervene and improve the country’s climate variability and livelihood situations. It recommends future policies, strategies, programs, and activities that focus on sustainable agriculture support, livelihood diversification, the strengthening of local institutions, and research on climate variability, adaptation, livelihood diversification, and food security. Livestock and agriculture are the backbone of Somaliland’s economy and people, providing most of the employment, GDP, foreign export income, and food security. However, these sectors are vulnerable to climate change and variability, which can harm food security, increase poverty, and displace rural populations. Therefore, understanding the impact of climate variability on livelihoods is crucial to address poverty reduction and food security. This review will be of public interest, as it will help government officials and experts in charge of developing and implementing plans and strategies that address the different constraints on livelihoods. It also provides a better understanding of climate change and livelihood situations in Somaliland.

description: The simulation of rare events is one of the key problems in atomistic simulations. Towards its solution a plethora of methods have been proposed. Here we combine two such methods metadynamics and inte-grated tempering sampling. In metadynamics the fluctuations of a carefully chosen collective variable are amplified, while in integrated tempering sampling the system is pushed to visit an approximately uniform interval of energies and allows exploring a range of temperatures in a single run. We describe our ap-proach and apply it to the two prototypical systems a SN2 chemical reaction and to the freezing of silica. The combination of metadynamics and integrated tempering sampling leads to a powerful method. In par-ticular in the case of silica we have measured more than one order of magnitude acceleration.

description: Utilizing asymptotic Pade-approximant methods, we estimate the three-loop order MS-bar coefficients of alpha_s^3[\log(μ^2/m^2_b(μ)]^k terms [k = {0,1,2,3}] within the $b \to u\ell^-\barν_\ell$ decay rate. Except for the coefficient of the k = 0 term, all other coefficients may also be obtained via renormalization-group (RG) methods. The relative errors in asymptotic Pade-approximant estimates of the k = {1,2,3} terms are found to be 5.1% or less, thereby providing an estimate of the theoretical uncertainty in the asymptotic Pade-approximant estimate of the RG-inaccessible k = 0 term. By a judicious choice in the renormalization scale parameter, we are able to extract |V_{ub}| from the inclusive decay rate to within 7% theoretical uncertainty.

description: A model, based on a noncommutative geometry, unifying general relativity with quantum mechanics, is further develped. It is shown that the dynamics in this model can be described in terms of one-parameter groups of random operators. It is striking that the noncommutative counterparts of the concept of state and that of probability measure coincide. We also demonstrate that the equation describing noncommutative dynamics in the quantum gravitational approximation gives the standard unitary evolution of observables, and in the "space-time limit" it leads to the state vector reduction. The cases of the spin and position operators are discussed in details.

description: Dissatisfaction among women and health professionals regarding the health care provided during the perinatal period has led to the development of another style of care, oriented towards encouraging and respecting the autonomy of women during the reproductive process, what has called ‘women’s empowerment’. The aim of this paper is to describe women’s perceptions of empowerment during the perinatal period and its relationship to the humanization of childbirth, individualized care, and a dignified treatment of their bodies. Study was carried with a descriptive qualitative exploratory methodology using six focus groups of between 5 and 8 participants (June 2020–June 2022). The groups were guided by a semi-structured questionnaire. Data analysis was performed according to the Taylor-Bodgan methodology. The number of participants was 39 (29 pregnant; the rest were less than 12 months postpartum). From the analysis of the data, nine categories arose: definition, benefits, harms, role of the midwife, relationship, essential aspects, knowledge, feelings, and improvements. As concluding remarks, participants perceive women’s empowerment in the perinatal period as something beneficial, although this is a term with which they are unfamiliar. They consider that the role of the midwife and the information received are fundamental elements in this empowerment. Finally, a close relationship is established between this term and others such as individualized care and the humanization of childbirth.

description: We study the spectral flow of the Wilson-Dirac operator H(m) with and without an additional Sheikholeslami-Wohlert (SW) term on a variety of SU(3) lattice gauge field ensembles in the range $0\le m \le 2$. We have used ensembles generated from the Wilson gauge action, an improved gauge action, and several two-flavor dynamical quark ensembles. Two regions in $m$ provide a generic characterization of the spectrum. In region I defined by $m\le m_1$, the spectrum has a gap. In region II defined by $m_1\le m \le 2$, the gap is closed. The level crossings in H(m) that occur in region II correspond to localized eigenmodes and the localization size decreases monotonically with the crossing point down to a size of about one lattice spacing. These small modes are unphysical, and we find the topological susceptibility is relatively stable in the part of region II where the small modes cross. We argue that the lack of a gap in region II is expected to persist in the infinite volume limit at any gauge coupling. The presence of a gap is important for the implementation of domain wall fermions.

description: Rhamnolipid is known for its potential for degradation of various harmful and toxic contaminants. However, there is a lack of reports of their effects on different biological systems. Hence, the present study focuses on the assessment of rhamnolipid mixture for their biocompatibility nature. The in vitro and in vivo toxicity studies on the mouse fibroblast cell line (L929) and rabbit skin surface respectively showed that the crude rhamnolipid mixture exhibits a nontoxic behavior (p Aedesalbo pictus larvae. However, studies on monocotyledonous and dicotyledonous seeds showed the toxic behavior of rhamnolipids above their critical micelle concentration values (5–200 mg.L − 1). The antimicrobial property with respect to bacteria was found to be more prominent toward Gram positive (0.5 ± 0.5 mg.L − 1) compared to Gram negative bacteria (2.0 ± 0.7 mg.L − 1) and it was least in case of fungi (2.0 ± 0.2 mg.L − 1). The present study opens up a possibility to study the effects of rhamnolipids on the flora and fauna existing at the site of their application to ensure that it effectively remediates the environment without causing any harm to the on-site living systems.
Radiative effects on false vacuum decay in Higgs-Yukawa theory

description: We derive fermionic Green's functions in the background of the Euclidean solitons describing false vacuum decay in a prototypal Higgs-Yukawa theory. In combination with appropriate counterterms for the masses, couplings and wave-function normalization, these can be used to calculate radiative corrections to the soliton solutions and transition rates that fully account for the inhomogeneous background provided by the nucleated bubble. We apply this approach to the archetypal example of transitions between the quasi-degenerate vacua of a massive scalar field with a quartic self-interaction. The effect of fermion loops is compared with those from additional scalar fields, and the loop effects accounting for the spacetime inhomogeneity of the tunneling configuration are compared with those where gradients are neglected. We find that scalar loops lead to an enhancement of the decay rate, whereas fermion loops lead to a suppression. These effects get relatively amplified by a perturbatively small factor when gradients are accounted for. In addition, we observe that the radiative corrections to the solitonic field profiles are smoother when the gradients are included. The method presented here for computing fermionic radiative corrections should be applicable beyond the archetypal example of vacuum decay. In particular, we work out methods that are suitable for calculations in the thin-wall limit, as well as others that take account of the full spherical symmetry of the solution. For the latter case, we construct the Green's functions based on spin hyperspherical harmonics, which are eigenfunctions of the appropriate angular momentum operators that commute with the Dirac operator in the solitonic background.

description: A pervious concrete area (50 m2) was constructed for a dual purpose: stormwater management and bicycle parking. It consisted of two subareas (PCa and PCb) with dissimilar characteristics of pervious concrete mixes in strength, durability and permeability. To make the construction more eco-friendly and economical, coal fly ash was incorporated as a partial cement replacement by 21.4% in the PCa pervious concrete mix. The PCb was constructed with an industry proprietary pervious concrete mix. The subbase water storage can retain 4.1 m3 of the infiltrated stormwater before discharging excess water to a storm drain. The drainage water had an improved water quality in turbidity, organic carbon, phosphorus and fecal coliform concentrations. However, it had high pH and conductivity which might cause a negative impact on the environment. The constructed area has been in active use since its opening, accommodating ~30 bicycles at once on the safe and comfort pervious surface.

description: We report multifrequency Very Long Baseline Array observations of twelve active galactic nuclei seen toward the Galactic anticenter. All of the sources are at |b| < 10 degrees and seven have |b| < 0.5 degrees. Our VLBA observations can detect an enhancement in the angular broadening of these sources due to an extended H II disk, if the orientation of the H II disk in the outer Galaxy is similar to that of the H I disk. Such an extended H II disk is suggested by the C IV absorption in a quasar's spectrum, the appearance of H I disks of nearby spiral galaxies, and models of Ly-alpha cloud absorbers and the Galactic fountain. We detect eleven of the twelve sources at one or more frequencies; nine of the sources are compact and suitable for an angular broadening analysis. A preliminary analysis of the observed angular diameters suggests that the H II disk does not display considerable warping or flaring and does not extend to large Galactocentric distances (R >~ 100 kpc). A companion paper (Lazio & Cordes 1997) combines these observations with those in the literature and presents a more comprehensive analysis.

description: In the context of the Kuramoto model of coupled oscillators with distributed natural frequencies interacting through a time-delayed mean-field, we derive as a function of the delay exact results for the stability boundary between the incoherent and the synchronized state and the nature in which the latter bifurcates from the former at the critical point. Our results are based on an unstable manifold expansion in the vicinity of the bifurcation, which we apply to both the kinetic equation for the single-oscillator distribution function in the case of a generic frequency distribution and the corresponding Ott-Antonsen(OA)-reduced dynamics in the special case of a Lorentzian distribution. Besides elucidating the effects of delay on the nature of bifurcation, we show that the approach due to Ott and Antonsen, although an ansatz, gives an amplitude dynamics of the unstable modes close to the bifurcation that remarkably coincides with the one derived from the kinetic equation. Further more, quite interestingly and remarkably, we show that close to the bifurcation, the unstable manifold derived from the kinetic equation has the same form as the OA manifold, implying thereby that the OA-ansatz form follows also as a result of the unstable manifold expansion. We illustrate our results by showing how delay can affect dramatically the bifurcation of a bimodal distribution.

description: The thermal dynamics of D-branes and of open superstrings in background gauge fields is studied. It is shown that D-brane dynamics forbids constant velocity motion at finite temperature. T-duality is used to interpret this feature as a consequence of the absence of an equilibrium state of charged strings at finite temperature in a constant background electric field, as a result of Debye screening of electric fields. The effective action for the Polyakov loop operator is computed and the corresponding screening solutions are described. The finite temperature theory is also used to illustrate the importance of carefully incorporating Wu-Yang terms into the string path integral for compact target spaces.

description: We present a generalized linear sigma model that includes both scalar and pseudoscalar glueballs in addition to a quark-antiquark as well as a four-quark chiral nonet. Utilizing the axial and trace anomalies of QCD (at the effective mesonic level), we aim to develope the most general structure of the Lagrangian which can be used to study the interaction of quarkonia with glueballs. We then study the effect of scalar glueball on the vacuum of the model by considering a decoupling limit in which the glueball fields are decoupled from quarkonia. This determines the properties of the pure scalar glueball and builds a practical foundation for determining the model parameters when the interactions are turned on.

description: This study aimed optimizes the inductively coupled plasma–atomic emission spectrometry (ICP-AES) conditions for the determination of macro and microelements in the flowers and leaves of Trifolium species. After the optimization of instrumental parameters, plasma robustness was achieved under the following conditions: RF power 1350 W, nebulizer flow rate 0.5 L min−1, coolant gas flow rate 12 L min−1, auxiliary gas flow rate 0.5 L min−1, flush pump rate 100 rpm, analysis pump rate 50 rpm, sample flow 0.5 mL min−1, and sample uptake delay 30 s. The limits of detection (LOD) and limits of quantification (LOQs) were lower than literature values. The most abundant microelement in leaves is Ca, followed by K, Mg, P, and Na, and in flowers was K, followed by Ca, P, Mg, and Na. The average contents of microelements decreased in the orders S > Fe > Si > Al > Zn > Mn > Cu > Ni > Co > Pb > Cr > As > Cd for flowers and S > Fe > Si > Mn > Al > Zn > Cu > Ni > Co > Pb > Cr > As > Cd for leaves. Chemometrics were used for grouping samples based upon the elemental contents.

description: We consider level crossing in the background of the sphaleron barrier for nondegenerate fermions. The mass splitting within the fermion doublets allows only for an axially symmetric ansatz for the fermion fields. In the background of the sphaleron we solve the partial differential equations for the fermion functions. We find little angular dependence for our choice of ansatz. We therefore propose a good approximate ansatz with radial functions only. We generalize this approximate ansatz with radial functions only to fermions in the background of the sphaleron barrier and argue, that it is a good approximation there, too.

description: We prove a generalized version of Kazhdan's theorem for canonical forms on Riemann surfaces. In the classical version, one starts with an ascending sequence $\{S_n \rightarrow S\}$ of finite Galois covers of a hyperbolic Riemann Surface $S$, converging to the universal cover. The theorem states that the sequence of forms on $S$ inherited from the canonical forms on $S_n$'s converges uniformly to (a multiple of) the hyperbolic form. We prove a generalized version of this theorem, where the universal cover is replaced with any infinite Galois cover. Along the way, we also prove a Gauss--Bonnet type theorem in the context of arbitrary infinite Galois covers.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: In the chirally symmetric Nambu--Jona-Lasinio model baryons are described as chiral solitons of mesonic quark--antiquark bound states. Hyperons are investigated in two complementary pictures: the bound state approach of Callan and Klebanov and the collective approach of Yabu and Ando. The latter is used to compute the strange vector form factors of the nucleon providing estimates for the strange electric mean square radius and the strange magnetic moment of the nucleon.

description: Procalcitonin (PCT) is an inflammatory marker with significance in the early diagnosis of sepsis. The label-free electrochemical impedance immunosensor has good prospects for the determination of this disease marker due to its cost-effectiveness, high specificity and simple operation. However, developing an immunosensor for procalcitonin faces challenges due to the absence of satisfactory electrodes. Herein, a novel label-free electrochemical impedance immunosensor using the three-dimensional (3D) flower-shaped gold nanoparticle@molybdenum(IV) sulfide/graphene (Au NPs@MoS2/graphene) composite is reported for procalcitonin. Under the optimal conditions, the immunosensor presents a linear response from 10 fg mL−1 to 50 ng mL−1 and an ultra-low detection limit of 2.3 fg mL−1 for for procalcitonin. The excellent performance is due to the unique 3D flower-shape and the synergistic effect of Au NPs@MoS2/graphene, generating a large surface area, high electrical conductivity, and increased immobilization of anti-PCT. Additionally, the immunosensor exhibits suitable specificity, stability, and reproducibility, and was used to determine procalcitonin in serum which may allow clinical screening and diagnosis of sepsis.

description: This study aimed to investigate the feasibility of identifying the geographical origin of peanuts by combining Raman spectroscopy with chemometrics. A total of 161 peanut samples were collected from Jilin, Jiangsu, and Shandong provinces in China, and their Raman spectra were collected. One-way analysis of variance (ANOVA) was used to analyze the difference in characteristic Raman spectra of peanuts from these locations. Raman spectroscopy combined with principal component analysis (PCA), k-nearest neighbor (k-NN), stepwise linear discriminant analysis (SLDA), and support vector machines (SVM) were used to classify the peanuts by province and Jilin Province city. One-way ANOVA indicated that the peak intensities at 2900, 1660, 1440, 1077, and 848 cm−1 had significant differences. The peaks at 2900, 1660, 1440, 1300, and 1077 cm−1 had significant differences in the Jilin Province city. The correct identification rates were highest for k-NN. This study demonstrates the identification of the origin of peanuts by Raman spectroscopy with chemometrics and may provide technical support for the traceability of other agricultural products.
Magnetism of the N=42 kagome lattice antiferromagnet

description: For the paradigmatic frustrated spin-half Heisenberg antiferromagnet on the kagome lattice we performed large-scale numerical investigation of thermodynamic functions by means of the finite-temperature Lanczos method for system sizes of up to N=42. We present the dependence of magnetization as well as specific heat on temperature and external field and show in particular that a finite-size scaling of specific heat supports the appearance of a low-temperature shoulder below the major maximum. This seems to be the result of a counterintuitive motion of the density of singlet states towards higher energies. Other interesting features that we discuss are the asymmetric melting of the 1/3 magnetization plateau as well the field dependence of the specific heat that exhibits characteristic features caused by the existence of a flat one-magnon band. By comparison with the unfrustrated square-lattice antiferromagnet the tremendous role of frustration in a wide temperature range is illustrated.

Bottom-up model for maximal $ν_μ - ν_τ$ mixing

Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We construct a model which provides maximal mixing between a pseudo-Dirac $ν_μ/ν_τ$ pair, based on a local $U(1)_{L_μ-L_τ}$ symmetry. Its strengths, weaknesses and phenomenological consequences are examined. The mass gap necessitated by the pseudo-Dirac structure is most naturally associated with the LSND anomaly. The solar neutrino problem then requires a light mirror or sterile neutrino. By paying a fine-tuning price to nullify the mass gap, one can also invoke $ν_e \to ν_{μ,τ}$ for the solar problem. The model predicts a new intermediate range force mediated by the light gauge boson of $U(1)_{L_μ-L_τ}$. Through the mixing of $μ$, $τ$ and $e$, this force couples to electrons and thus may be searched for in precision ``gravity'' experiments.

Truncation Effects in Monte Carlo Renormalization Group Improved Lattice Actions

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We study truncation effects in the SU(3) gauge actions obtained by the Monte Carlo renormalization group method. By measuring the heavy quark potential we find that the truncation effects in the actions coarsen the lattice by 40-50 % from the original blocked lattice. On the other hand, we find that rotational symmetry of the heavy quark potentials is well recovered on such coarse lattices, which may indicate that rotational symmetry breaking terms are easily cancelled out by adding a short distance operator. We also discuss the possibility of reducing truncation effects.

Recurrence time correlations in random walks with preferential relocation to visited places
Creators: name: Campos, Daniel
name: Méndez, Vicenç
Publisher: name: arXiv
Year: 2018
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Random walks with memory typically involve rules where a preference for either revisiting or avoiding those sites visited in the past are introduced somehow. Such effects have a direct consequence on the statistics of first-passage and subsequent recurrence times through a site; typically, a preference for revisiting sites is expected to result in a positive correlation between consecutive recurrence times. Here we derive a continuous-time generalization of the random walk model with preferential relocation to visited sites proposed in [Phys. Rev. Lett. 112, 240601] to explore this effect, together with the main transport properties induced by the long-range memory. Despite the highly non-Markovian character of the process, our analytical treatment allows us to (i) observe the existence of an asymptotic logarithmic (ultraslow) growth for the mean square displacement, in accordance to the results found for the original discrete-time model, and (ii) confirm the existence of positive correlations between first-passage and subsequent recurrence times. This analysis is completed with a comprehensive numerical study which reveals, among other results, that these correlations between first-passage and recurrence times also exhibit clear signatures of the ultraslow dynamics present in the process.
