description: We discuss a purely variational approach to the study of a wide class of second order nonhomogeneous dissipative hyperbolic PDEs. Precisely, we focus on the wave-like equations that present also a nonzero source term and a first-order-in-time linear term. The paper carries on the research program initiated in (Serra&Tilli'12), and developed in (Serra&Tilli'16), (Tentarelli&Tilli '18), on the De Giorgi approach to hyperbolic equations.

description: We derive Feynman rules for gauge theories exhibiting spontaneous symmetry breaking using the real-time formalism of finite temperature field theory. We also derive the thermal propagators where only the physical degrees of freedom are given thermal boundary conditions. We analyse the abelian Higgs model and find that these new propagators simplify the calculation of the thermal contribution to the self energy.

description: We calculate the form factors and the coupling constant in the $ρD^* D^*$ vertex in the framework of QCD sum rules. We evaluate the three point correlation functions of the vertex considering both $ρ$ and $D^*$ mesons off--shell. The form factors obtained are very different but give the same coupling constant: $g_{ρD^* D^*} = 6.6 \pm 0.31$. This number is 50% larger than what we would expect from SU(4) estimates.

description: Patch-clamp electrophysiological recordings of neuronal activity requires a large amount of space and equipment. The technique is difficult to master and not conducive for demonstration to more than a few medical students. Therefore, neurophysiological education is mostly limited to classroom based pedagogies such as lectures. However, demonstration of concepts such as changes in membrane potential and ion channel activity is best achieved using hands-on approaches. This article details an in silico activity suitable for large groups of medical students, which demonstrates the key concepts in neurophysiology using the LabAXON simulation software. Learning activities in our practical include: 1) measurements of voltage and time parameters of the neuronal action potential and its relationship to the Nernst potentials of Na+ and K+; 2) determination of the stimulus threshold to evoke action potentials; 3) demonstration of the refractory period of an action potential; 4) voltage-clamp experiments to determine the current-voltage relationship of voltage-gated Na+ and K+ channels, the voltage-dependence of, and recovery from, inactivation of voltage-gated Na+ channels. We emphasized the accuracy of quantitative measurements, as well as the correct use of units. The level of difficulty of the activity can be altered through different multiple choice questions relating to material introduced in the associated lectures. This practical activity is suitable for different class sizes and is adaptable for delivery using online platforms. Student feedback showed that the students felt the activity helped them consolidate their understanding of the lecture material.
Fermion mass in the Wilson-Yukawa approach for chiral Yukawa theory

description: We consider a modification of the Wilson-Yukawa model to overcome its difficulty that the fermion mass is not proportional to the Higgs vacuum expectation value. In the modification scalar and fermionic regulator fields are introduced so that all the physical fermion fields possess shift symmetry when the Yukawa coupling vanishes. With the fermionic hopping parameter expansion it is shown that the fermion mass is proportional to the Higgs vacuum expectation value and that the coupling of fermion to the external gauge field can be chiral if the hopping parameter of the scalar regulator field is taken to the critical value.

description: We model competition between risk-neutral principals who hire weakly risk-averse agents to produce a good of variable quality. The agent can increase the likelihood of producing a high-quality good by providing costly effort. We demonstrate that, when the agent is strictly risk-averse, the cost of providing incentives increases in the number of other firms in the industry. We characterize conditions under which the first-best outcome involves each firm inducing high effort. We then consider firms in competition, and identify parameter conditions under which (i) each firm induces high effort in the short run and low effort in the long run (ii) the first-best outcome has each firm inducing high effort, but long-run equilibrium results in each firm inducing low effort. Thus, in the long run, the average quality in the industry deteriorates, and increased competition leads to a “race to the bottom” in quality.

description: The existing derivations of a heavy quark effective theory (HQET) are analyzed beyond the next-to-leading order in $1/m$. With one exception they are found to be incorrect. The problem is a wrong normalization of the heavy quark field in the effective theory. We argue that the correct effective theory should be given by a Foldy--Wouthuysen type field transformation to all orders in $1/m$. The renormalization of the resulting Lagrangian to order $1/m^2$ is performed allowing for inclusion of effects arising through vacuum polarization. Our results for the anomalous dimensions disagree with the existing ones. Some applications are considered.

description: The presence of communities, which are groups of highly cross referenced pages together representing a single concept, is a striking feature of the World Wide Web. Quite often a group of communities, each topically coherent within itself, may be related through a common concept manifested in each of them. Motivated by this observation, we present a method for query-driven conceptual browsing for exploring concepts on the Web starting from a userspecified query. We show how this idea is related to prior work on learning concept maps and on Web Mining, and discuss the application of conceptual browsing for user-driven exploration and discovery of new concepts on the Web.

description: We consider the robustness of small-field inflation in the presence of scalar field inhomogeneities. Previous numerical work has shown that if the scalar potential is flat only over a narrow interval, such as in commonly considered inflection-point models, even small-amplitude inhomogeneities present at the would-be onset of inflation at $τ= τ_i$ can disrupt the accelerated expansion. In this paper, we parametrise and evolve the inhomogeneities from an earlier time $τ_{IC}$ at which the initial data were imprinted, and show that for a broad range of inflationary and pre-inflationary models, inflection-point inflation withstands initial inhomogeneities. We consider three classes of perturbative pre-inflationary solutions (corresponding to energetic domination by the scalar field kinetic term, a relativistic fluid, and isotropic negative curvature), and two classes of exact solutions to Einstein's equations with large inhomogeneities (corresponding to a stiff fluid with cylindrical symmetry, and anisotropic negative curvature). We derive a stability condition that depends on the Hubble scales $H(τ_ i)$ and $H(τ_{IC})$, and a few properties of the pre-inflationary cosmology. For initial data imprinted at the Planck scale, the absence of an inhomogeneous initial data problem for inflection-point inflation leads to a novel, lower limit on the tensor-to-scalar ratio.

description: Using the Zaragoza proposal for lattice chiral gauge fermions, the S, U and Δρparameters have been calculated at one loop. It is shown that the continuum values for these quantities can be reproduced without requiring explicit fine tuning of counterterms. Furthermore, fermion fields doubling is not necessary. To the best of our knowledge, the Zaragoza proposal is the only scheme which has these properties. A necessary (although not sufficient) symmetry is found to support the calculations. Previous results for some of these parameters in other lattice chiral regularizations are revisited in the light of this symmetry.

description: Sustainable Development is a notion of development with very less destruction to the society, environmental ecosystem, and other far-away factors which may occur caused by so-called “development”. Consideration of sustainable development in Indian construction industry majorly focuses on energy efficiency, reducing CO2 emission, less focuses on economic aspect and social consideration of sustainability in majorly neglected as per literature studies. Whereas, Energy-efficient buildings are much more expensive when compared to conventional buildings, as this shows the globally shared experience that a building that is already expensive will become more expensive with energy-saving fixtures in the market. This issue of affordability of housing has rapidly increased in India, which partly shows housing supply fails to satisfy housing demand. The research subject justifies that dispense related issues can be addressed with behavioural adoption reconciliations. Therefore, understanding factors affecting sustainable housing enables a broader simplification of problems.

description: In a SUSY theory with a spontaneously broken global symmetry, G, if the scale of SUSY breaking, $M_s$ is smaller than the scale $M_G$ of the global symmetry, the Nambu-Goldstone boson, $χ$ is accompanied by two massive superpartners ( a fermionic, $Ψ_χ$ and a scalar $σ_χ$) with mass of order $M_s$. Cosmological considerations imply stringent constraints on the couplings of $Ψ_χ$ and $σ_χ$. Application of these considerations to the supersymmetric singlet Majoron model leads to an upper limit on the scale $V_{BL}$ of global $U(1)_{B-L}$ symmetry to be less than $10^4 GeV$, for resonable values of parameters in the theory.

description: In a recent paper [5], we addressed the problem of finding a minimum-cost spanning tree T for a given undirected graph G=(V,E) with maximum node-degree at most a given parameter B>1. We developed an algorithm based on Lagrangean relaxation that uses a repeated application of Kruskalrsquos MST algorithm interleaved with a combinatorial update of approximate Lagrangean node-multipliers maintained by the algorithm. In this paper, we show how to extend this algorithm to the case of Steiner trees where we use a primal-dual approximation algorithm due to Agrawal, Klein, and Ravi [1] in place of Kruskalrsquos minimum-cost spanning tree algorithm. The algorithm computes a Steiner tree of maximum degree and total cost that is within a constant factor of that of a minimum-cost Steiner tree whose maximum degree is bounded by B. However, the running time is quasi-polynomial.

description: L'idée de planter des rangées de ligneux pérennes dans des champs de grandes cultures ou des champs de légumes, mérite d'être explorée par les agriculteurs cherchant à obtenir un revenu supplémentaire à long terme, plutôt qu'un revenu fondé uniquement sur une production annuelle, et à accroître la résilience environnementale de leur système. Il est recommandé que les arbres et arbustes plantés présentent certaines des caractéristiques suivantes : i) produire un ou plusieurs produits (bois, noix, etc.) avec une demande locale suffisante, ii) avoir des racines profondes pour réduire la concurrence avec les cultures principales, iii) ne pas produire de composés allélochimiques ou acides qui empêcheraient certaines cultures de pousser sous eux. Les cultures associées, plantées dans les allées entre les rangées d'arbres, peuvent être : 1) des cultures céréalières et fourragères ; 2) fruits, baies, plantes ornementales ou aromatiques / médicinales ; ou 3) cultures produisant de la biomasse. Les premières années, les cultures de plein soleil peuvent être cultivées dans les allées. Au fur et à mesure que les arbres grandissent, ils vont augmenter la surface d'ombre, la compétition pour l'eau et les nutriments ainsi que le niveau d'humidité, ils vont aussi abaisser les températures et l'impact du vent, de sorte que les espèces tolérantes à l'ombre conviendront mieux. Les opérations de gestion de la ligne d'arbres sont le contrôle des mauvaises herbes, l'élagage et l'éclaircie.

description: In the present paper we have developed a concept of parallel ordinary (O) and mirror (M) worlds. We have shown that in the case of a broken mirror parity (MP), the evolutions of fine structure constants in the O- and M-worlds are not identical. It is assumed that E_6-unification inspired by superstring theory restores the broken MP at the scale \sim 10^{18} GeV, what unavoidably leads to the different E_6-breakdowns at this scale: E_6 \to SO(10)\times U(1)_Z - in the O-world, and E'_6 \to SU(6)'\times SU(2)'_Z - in the M-world. Considering only asymptotically free theories, we have presented the running of all the inverse gauge constants α_i^{-1} in the one-loop approximation. Then a `quintessence' scenario is discussed for our model of accelerating universe. Such a scenario is related with an axion (`acceleron') of a new gauge group SU(2)'_Z which has a coupling constant g_Z extremely growing at the scale Λ_Z\sim 10^{-3} eV.

description: En règle générale, les feuilles fraîches ou bien conservées d'arbres sont de bonnes sources d'alimentation, parfois meilleures que les graminées communément cultivées. Les fourrages ligneux sont également une bonne source de micronutriments, notamment de vitamines et de minéraux spécifiques. Lorsque les animaux ont accès à des arbres ou à des haies, ils se dirigent naturellement vers eux, montrant leur intérêt à les pâturer. La proportion de fourrage ligneux peut atteindre respectivement 12 à 55%, 20 à 76% et 60 à 93% du régime alimentaire des bovins, ovins et caprins. Les chèvres tolèrent des niveaux élevés de fourrages ligneux dans leur régime alimentaire en raison de leur salive qui peut se lier aux tanins, et de leur foie de grande taille qui traite efficacement les tanins. Bien que le système digestif des ruminants soit bien adapté à un régime à base d'herbe, il n'empêche pas une digestion efficace du fourrage ligneux. Le feuillage est accessible jusqu'à une hauteur de 2 m pour les bovins et de 1,2 m pour les ovins. Les chèvres arrivent à pâturer quasiment sur toute la hauteur de l'arbre.

description: We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of CP violation in the process $e^-e^+ \to W^-W^+$. These asymmetries are sensitive to different linear combinations of the CP violating form factors in the three gauge boson $W^-W^+$ production vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic modes of $W$'s decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct CP--odd observables are also employed. These CP violating observables are illustrated in the generalized Left-Right Model and the Charged Higgs Model.

description: A search for pair production of heavy scalar leptoquarks (LQs), each decaying into a top quark and a $τ$ lepton, is presented. The search considers final states with an electron or a muon, one or two $τ$ leptons that decayed to hadrons, and additional jets. The data were collected in 2016 in proton-proton collisions at $\sqrt{s}=$ 13 TeV with the CMS detector at the LHC, and correspond to an integrated luminosity of 35.9 fb$^{-1}$. No evidence for pair production of LQs is found. Assuming a branching fraction of unity for the decay LQ$ \to $t$τ$, upper limits on the production cross section are set as a function of LQ mass, excluding masses below 900 GeV at 95% confidence level. These results provide the most stringent limits to date on the production of scalar LQs that decay to a top quark and a $τ$ lepton.

Le comportement des animaux d'élevage se distingue en plusieurs catégories : la locomotion, l'instinct maternel, la nutrition, la reproduction, la sociabilité et le repos. L'accès aux arbres peut être bénéfique pour tout cela. Le comportement quotidien d'un animal dépend en grande partie du maintien de l'équilibre, qu'on appelle aussi l'homéostasie. Par exemple, lorsqu'un animal a faim, il se déplace et pâture. De même, quand il fait chaud ou froid, il cherche de l'ombre ou un abri et les arbres, les arbustes et les brise-vent peuvent offrir une protection efficace. La condition du pelage est importante pour le maintien de la santé des animaux. Les troncs et les branches des arbres sont facilement utilisés comme grattoirs. Les mères de toutes les espèces recherchent un abri disponible lors de l'accouchement.

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.

description: Accurate surgery duration estimation is necessary for optimal OR planning, which plays an important role in patient comfort and safety as well as resource optimization. It is, however, challenging to preoperatively predict surgery duration since it varies significantly depending on the patient condition, surgeon skills, and intraoperative situation. In this paper, we propose a deep learning pipeline, referred to as RSDNet, which automatically estimates the remaining surgery duration (RSD) intraoperatively by using only visual information from laparoscopic videos. Previous state-of-the-art approaches for RSD prediction are dependent on manual annotation, whose generation requires expensive expert knowledge and is time-consuming, especially considering the numerous types of surgeries performed in a hospital and the large number of laparoscopic videos available. A crucial feature of RSDNet is that it does not depend on any manual annotation during training, making it easily scalable to many kinds of surgeries. The generalizability of our approach is demonstrated by testing the pipeline on two large datasets containing different types of surgeries: 120 cholecystectomy and 170 gastric bypass videos. The experimental results also show that the proposed network significantly outperforms a traditional method of estimating RSD without utilizing manual annotation. Further, this work provides a deeper insight into the deep learning network through visualization and interpretation of the features that are automatically learned.

description: The objective of this study was to record the clinical, neuro-radiological, and systemic features of patients with septo-optic dysplasia (SOD). A retrospective review of patients was conducted to identify patients with features consistent with SOD over a 6-year period, including optic nerve hypoplasia with agenesis of midline structures, along with an absent septum pellucidum and/or agenesis of the corpus callosum. Thirty-three patients were identified. The male to female ratio was 2:1, while the median age at diagnosis was 5 years (interquartile range = 10 years, range = 0–44 years). Optic nerve hypoplasia (ONH) was bilateral in 81.81% of cases (n = 27) and unilateral in 18.18% of cases (n = 6), with three cases in each eye. Developmental delay was documented in 24.2% (n = 8). The most frequent magnetic resonance imaging features that were consistent with SOD included: isolated absent septum pellucidum reported in 51.51% (n = 17); isolated corpus callosum agenesis in 33.33% (n = 11); and both absent septum pellucidum and corpus callosum agenesis in 15.15% (n = 5). Pituitary gland abnormalities, including pituitary hypoplasia in 9% (n = 3) or hypoplasia of pituitary infundibulum in 6% (n = 2) were less common. Pituitary hormonal abnormalities were present in 50% of the 10 tested patients (n = 5). Although bilateral ONH is more frequent, hypoplasia of just one optic nerve could be a presenting feature of SOD. Therefore, additional neuro-imaging is important for a diagnosis in cases of unilateral and bilateral ONH and a multidisciplinary approach is beneficial.

description: Since the early 1970' s there has been a proliferation of quality of working life (QWL) projects. These projects attempt to bring about fundamental changes in organizational and labor-management relationships. Basically, they illustrate new ways to restructure work in order to improve the organizational effectiveness. This paper reviews QWL efforts in the 1970's and suggests possible characteristics of QWL projects in the 1980's.
Research Software Engineering and Software Engineering Research: Bridging Knowledge Gaps
Creators: name: Jay, Caroline
Publisher: name: Zenodo
Year: 2024

description: In June 2024, Caroline Jay from the Software Sustainability Institute and The University of Manchester gave her talk on 'Research Software Engineering and Software Engineering Research: Bridging Knowledge Gaps'.

Abstract: Research software underpins computational research across many academic disciplines, and we might therefore assume that software engineering researchers (SERs), who investigate and develop methods to improve the quality of software and its lifecycle processes, have a strong interest in this growing area. Conversely, we might assume that research software engineers (RSEs) who must select, customize, and apply software engineering methods to create research software have an interest in the production and adoption of novel methods. Whilst there is strong theoretical overlap between these communities, in reality they interact very little. This talk will provide a overview of and personal reflection on a recent Dagstuhl seminar bringing RSEs and SERs together, covering the challenges of tribalism and terminology, and the opportunities of a new interdisciplinary research area.

description: In this paper we consider pairs of interacting electrons moving in a simple quantum wire, namely the half-line. In particular, we extend the results obtained in [arXiv:1708.03753] by allowing for contact interactions of the Lieb-Liniger type between the two electrons constituting the pair. We construct the associated Hamiltonian rigorously and study its spectral properties. We then investigate Bose-Einstein condensation of pairs and prove, as a main result, the existence of condensation whenever the Hamiltonian has a non-trivial discrete spectrum. Most importantly, condensation is proved for very weak and very strong contact interactions.

description: To improve the properties of traditional Indian lime mortar, urine is applied. In this study, urea (fertiliser) was used instead of urine to provide a more sanitary choice. Urea is applied in varying amounts, such as 1%, 2%, 3%, 4%, and 5%, using Lime Mortar 1:3 and Fly Ash Lime Gypsum (FAL-G) paste. The resulting composites were cast into 50-square-centimeter cubes and tested for weight density, water absorption, and compressive strength.The output of simple lime mortar cubes and plain FAL-G cubes was compared. FAL-G shows better properties with 3% urea than lime mortar.

description: From the time of Locke (1967), theoretical analysis of the role of government distinguished those services that can be provided at lowest cost if provided collectively. These goods and services, usually called public goods, are part of a potentially larger class of goods that are subject to external economies or diseconomies in production or consumption. Modern governments do not limit their activities to the provision of public goods and the elimination of external effects. Governments supply services that can be produced privately. At times, public and private supply coexist. Housing services, medical care and education are examples, but so too are consumer protection, safety and many of the so-called regulatory activities.

description: We study quantum transport after an inhomogeneous quantum quench in a free fermion lattice system in the presence of a localised defect. Using a new rigorous analytical approach for the calculation of large time and distance asymptotics of physical observables, we derive the exact profiles of particle density and current. Our analysis shows that the predictions of a semiclassical approach that has been extensively applied in similar problems match exactly with the correct asymptotics, except for possible finite distance corrections close to the defect. We generalise our formulas to an arbitrary non-interacting particle-conserving defect, expressing them in terms of its scattering properties.

Quantum-Mechanical Relation between Atomic Dipole Polarizability and the van der Waals Radius

description: The atomic dipole polarizability, $α$, and the van der Waals (vdW) radius, $R_{\rm vdW}$, are two key quantities to describe vdW interactions between atoms in molecules and materials. Until now, they have been determined independently and separately from each other. Here, we derive the quantum-mechanical relation $R_{\rm vdW} = const. \timesα^{1/7}$ which is markedly different from the common assumption $R_{\rm vdW} \propto α^{1/3}$ based on a classical picture of hard-sphere atoms. As shown for 72 chemical elements between hydrogen and uranium, the obtained formula can be used as a unified definition of the vdW radius solely in terms of the atomic polarizability. For vdW-bonded heteronuclear dimers consisting of atoms $A$ and $B$, the combination rule $α= (α_A + α_B)/2$ provides a remarkably accurate way to calculate their equilibrium interatomic distance. The revealed scaling law allows to reduce the empiricism and improve the accuracy of interatomic vdW potentials, at the same time suggesting the existence of a non-trivial relation between length and volume in quantum systems.

description: The copper(II) complexes of the picolinic acid bydrazide (PH), the dipicolinic acid dibydrazide (DPH), and the 2,2'-bisacylbydrazide of 3,3'-bipyridine (DAR) ligand systems have been prepared and have been characterized by infrared spectroscopy. Coordination has been proposed to occur between the terminal amine, the amide nitrogen, and the ring nitrogen in each of the respective complexes.

Evidence for the loss of the amide hydrogen upon complexation of PH, DPH, and DAH with copper(II) has been observed by the n.m.r. study of the zinc(II) complexes of the PH and DAH ligand systems. This is in support of the structures proposed above for the copper(II) complexes.
Weakly Interacting Topological Insulators: Quantum Criticality and Renormalization Group Approach

description: For D-dimensional weakly interacting topological insulators in certain symmetry classes, the topological invariant can be calculated from a D- or (D+1)-dimensional integration over a certain curvature function that is expressed in terms of single-particle Green's functions. Based on the divergence of curvature function at the topological phase transition, we demonstrate how a renormalization group approach circumvents these integrations and reduces the necessary calculation to that for the Green's function alone, rendering a numerically efficient tool to identify topological phase transitions in a large parameter space. The method further unveils a number of statistical aspects related to the quantum criticality in weakly interacting topological insulators, including correlation function, critical exponents, and scaling laws, that can be used to characterize the topological phase transitions driven by either interacting or noninteracting parameters. We use 1D class BDI and 2D class A Dirac models with electron-electron and electron-phonon interactions to demonstrate these principles, and find that interactions may change the critical exponents of the topological insulators.

description: There have been very few countries with a large measure of economic freedom. Rabushka (1978) reports on about a dozen small states that had free market economies before the 19th century. Most of them disappeared. Free market principles spread through Western Europe and North America in the 19th century, but regulation and taxation have grown in the 20th century in all of these countries. Governments have grown in size and power and now have a substantial regulatory role in most western countries. In the last twenty-five years taxes have risen faster than output in all the principal market economies. Nutter (1978).

We briefly comment on the significance of the resulting $F_π(M_{J/ψ}^2)$.

description: A code algebra $A_C$ is a non-associative commutative algebra defined via a binary linear code $C$. We study certain idempotents in code algebras, which we call small idempotents, that are determined by a single non-zero codeword. For a general code $C$, we show that small idempotents are primitive and semisimple and we calculate their fusion law. If $C$ is a projective code generated by a conjugacy class of codewords, we show that $A_C$ is generated by small idempotents and so is, in fact, an axial algebra. Furthermore, we classify when the fusion law is $\mathbb{Z}_2$-graded. In doing so, we exhibit an infinite family of $\mathbb{Z}_2 \times \mathbb{Z}_2$-graded axial algebras - these are the first known examples of axial algebras with a non-trivial grading other than a $\mathbb{Z}_2$-grading.
