Subjects: Singlet-states
permutation symmetry

population imbalance

description: The present work is the result of a 3-year project in Prof. Levitt’s research group in Southampton (UK). It comprises a theoretical and an experimental part. The theoretical part derives a formalization of long-lived states (LLS) in terms of nuclear spin permutation symmetry. This formalism is suitable in particular with multi-spin systems. A few advantages originate: This formalism derives a convenient representation of LLS as spin population imbalances of nuclear spin states spanning across different irreducible representations. A classification of the symmetry properties of the system’s complete Hamiltonian permits to easily find out the number of conserved quantities (under a certain set of introduced approximations). A generalization of the Sørensen bound in presence of exchange symmetry of the nuclear spin Hamiltonian, initially analysed by Nielsen and Sørensen and recently investigated by Levitt, is included as it allows to set extra boundary conditions. The experimental part demonstrates the ubiquitous nature of LLS. They are identified and detected either in nearly chemically, magnetic and far from magnetic equivalent systems. The discovery of a more than one hour LLS in a hydrophobic naphthalene derivative molecule is currently fostering the theoretical investigation on field dependent relaxation mechanisms and on practical ways to store and retrieve polarization over an extended time interval. A water soluble version of the molecule has been also investigated and is briefly presented. The naphthalene derivatives experiments are still work in progress. Finally a brief section is dedicated to preliminary hyperpolarization experiments on the hydrophobic naphthalene derivative performed at Ardenkjaer-Larsen’s research group in DTU-Copenhagen as a first attempt to store hyperpolarized signal for long time.

description: We argue that the pseudogap phase may be an attribute of the non-BCS pairing of quantum-critical, diffusive fermions near the antiferromagnetic quantum critical point. We derive and solve a set of three coupled Eliashberg-type equations for spin-mediated pairing and show that in some $T$ range below the pairing instability, there is no feedback from superconductivity on fermionic excitations, and fermions remain diffusive despite of the pairing. We conject that in this regime, fluctuations of the pairing gap destroy the superconducting condensate but preserve the leading edge gap in the fermionic spectral function.

description: Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microscopic imaging of antiferromagnetic domains is one of the key prerequisites for understanding physical principles of the device operation. However, adapting common magnetometry techniques to the dipolar-field-free antiferromagnets has been a major challenge. Here we demonstrate in a collinear antiferromagnet a thermoelectric detection method by combining the magneto-Seebeck effect with local heat gradients generated by scanning far-field or near-field techniques. In a 20-nm epilayer of uniaxial CuMnAs we observe reversible 180∘ switching of the Néel vector via domain wall displacement, controlled by the polarity of the current pulses. We also image polarity-dependent 90∘ switching of the Néel vector in a thicker biaxial film, and domain shattering induced at higher pulse amplitudes. The antiferromagnetic domain maps obtained by our laboratory technique are compared to measurements by the established synchrotron-based technique of x-ray photoemission electron microscopy using x-ray magnetic linear dichroism.

description: Perturbation analysis of Markov chains provides bounds on the effect that a change in a Markov transition matrix has on the corresponding stationary distribution. This paper compares and analyzes bounds found in the literature for finite and denumerable Markov chains and introduces new bounds based on series expansions. We discuss a series of examples to illustrate the applicability and numerical efficiency of the various bounds. Specifically, we address the question on how the bounds developed for finite Markov chains behave as the size of the system grows. In addition, we provide for the first time an analysis of the relative error of these bounds. For the case of a scaled perturbation we show that perturbation bounds can be used to analyze stability of a stable Markov chain with respect to perturbation with an unstable chain.

description: It is a long-standing important issue in heavy fermion physics whether $f$-electrons are itinerant or localized when the magnetic order occurs. Here we report the {\it in situ} scanning tunneling microscopy observation of the electronic structure in epitaxial thin films of CeRhIn$_5$, a prototypical heavy fermion compound with antiferromagnetic ground state. The conductance spectra above the Néel temperature $T_N$ clearly resolve the energy gap due to the hybridization between local 4$f$ electrons and conduction bands as well as the crystal electric field excitations. These structures persist even below $T_N$. Moreover, an additional dip in the conductance spectra develops due to the antiferromagnetic order. These results provide direct evidence for the presence of itinerant heavy $f$-electrons participating in the Fermi surface even in the magnetically ordered state of CeRhIn$_5$.

description: Tetradium ruticarpum (Juss.) Benth. belong to the family of Rutaceae. The complete and nearly ripe fruits of T. ruticarpum is used as traditional Chinese medicine and phytochemical investigations have been conducted on extracts of the seeds of T. ruticarpum to provide scientific validation of its properties. In this study, we successfully isolated two new quinolone alkaloids (1-2) from the MeOH extractive of nearly ripe fruits of T. ruticarpum. The structure elucidation of these compounds was determined by one- and two-dimensional nuclear magnetic resonance, ultraviolet and electrospray ionisation time-of-flight mass spectrometry. This finding expands the understanding of the natural constituents of the Rutaceae, in particular, the Tetradium genera.

description: Objective: This systematic review aims to evaluate the applications of 3D printing technology in chest wall resections for cancer, with a focus on its impact on surgical precision, patient recovery, and post-operative outcomes. The central research question posed is: What are the applications and outcomes of 3D printing technology in chest wall resections for cancer? Methods: A comprehensive literature search was conducted using online databases including PubMed, focusing on studies published in the last five years. Inclusion criteria were adult patients, English language, and utilisation of 3D printing technology for chest wall cancer surgery. Data were extracted from fourteen studies that met these criteria, and a qualitative synthesis was performed to identify common themes and findings. Results: The review identified several significant benefits associated with the use of 3D-printed implants in chest wall reconstruction. These included enhanced surgical precision, reduced operative time, improved patient recovery outcomes, and superior aesthetic and functional results. The tailored fit of 3D-printed implants allowed for more accurate resections and minimised the need for intraoperative adjustments, contributing to reduced operative times and lower complication rates. Patients generally reported high levels of satisfaction with both functional and aesthetic outcomes. Additionally, the review highlighted the potential for 3D-printed implants to be customised for complex and extensive chest wall defects, further improving surgical outcomes. Conclusions: The application of 3D printing technology in chest wall resections for cancer presents a significant advancement in surgical precision and patient outcomes. Despite encouraging results, further large-scale studies and standardised protocols are needed to fully validate these benefits and integrate 3D printing into routine clinical practice.

L’espèce niche dans les cavités, principalement dans des trous au sol et entre les racines de Poacées, famille végétale identifiée sur les toitures où l’espèce a été capturée. Elle est typique des milieux xérothermophiles, comme les carrières et gravières, ce n’est pas donc étonnant que cette espèce ait été capturée sur des toitures végétalisées extensives. Il s’agit d’une espèce polylectique et solitaire. Sa période de vol s’étend de mai à septembre. Les trois individus de cette espèce ont été piégés en fin de période de vol (5.7.–15.8.).

description: Vainikka, A. & Roeper, T. (1995) Abstract operators in early acquisition. Linguistic Review, 12, 275-310.
description: We wish to argue in this paper that abstract operators block extraction fo children (as they do for adults), and that such operators are available in children's syntax already from about the age of three onwards. In particular, we will be concerned with abstract operators in purpose clauses and related constructions in the production data (for example, And the chicken gave it to Bozo to eat, Adam 3;4 file 28, see Appendix A) in a comprehension experiment (for example Where did the boy buy it to splash on his face?). Given the early occurrence of these phonologically null but syntactically complex elements, we propose that the notion of an operator is something very basic in Universal Grammar and that this notion is available as soon as the appropriate syntactic position is available at S-structure.
Episodic accretion in magnetically layered protoplanetary discs

description: We study protoplanetary disc evolution assuming that angular momentum transport is driven by gravitational instability at large radii, and magnetohydrodynamic (MHD) turbulence in the hot inner regions. At radii of the order of 1 AU such discs develop a magnetically layered structure, with accretion occurring in an ionized surface layer overlying quiescent gas that is too cool to sustain MHD turbulence. We show that layered discs are subject to a limit cycle instability, in which accretion onto the protostar occurs in bursts with an accretion rate of 10^{-5} solar masses / yr, separated by quiescent intervals where the accretion rate is 10^{-8} solar masses / yr. Such bursts could lead to repeated episodes of strong mass outflow in Young Stellar Objects. The transition to this episodic mode of accretion occurs at an early epoch (t < 1 Myr), and the model therefore predicts that many young pre-main-sequence stars should have low rates of accretion through the inner disc. At ages of a few Myr, the discs are up to an order of magnitude more massive than the minimum mass solar nebula, with most of the mass locked up in the quiescent layer of the disc at around 1 AU. The predicted rate of low mass planetary migration is reduced at the outer edge of the layered disc, which could lead to an enhanced probability of giant planet formation at radii of 1-3 AU.

Spin-flavor oscillations of Dirac neutrinos in matter under the influence of a plane electromagnetic wave

Publisher: name: arXiv

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

description: We study oscillations of Dirac neutrinos in background matter and a plane electromagnetic wave. First, we find the new exact solution of the Dirac-Pauli equation for a massive neutrino with the anomalous magnetic moment electroweakly interacting with matter under the influence of a plane electromagnetic wave with the circular polarization. We use this result to describe neutrino spin oscillations in the external fields in question. Then we consider several neutrino flavors and study neutrino spin-flavor oscillations in this system. For this purpose we formulate the initial condition problem and solve it accounting for the considered external fields. We derive the analytical expressions for the transition probabilities of spin-flavor oscillations for different types of neutrino magnetic moments. These analytical expressions are compared with the numerical solutions of the effective Schrödinger equation and with the findings of other authors. In particular, we reveal that a resonance in neutrino spin-flavor oscillations in the considered external fields cannot happen contrary to the previous claims. Finally, we briefly discuss some possible astrophysical applications.

Computational characterisation of protein interaction sites: from small ligand pockets to large domain interfaces
Creators: name: Vianello, Francesca
Publisher: name: Imperial College London
Year: 2020

description: Protein-Protein Interactions (PPIs) are central to all regulatory processes in nature and are therefore considered crucial nodes in disease pathways and particularly attractive drug targets. However, the size and complexity of protein interfaces pose significant challenges to drug discovery, as effective ligand design requires knowledge of the interactions at the atomistic and bond-specific level. We propose the application of bond-to-bond propensity, a graph-theoretical methodology based on the exploration of the edge space of a protein network constructed from the atomic coordinates and chemical interactions between atoms, as an effective method for the structural characterisation of PPIs. We showcase how this approach can be used to describe different levels of allosteric complexity — from small ligand-binding pockets to large protein-protein interfaces. The scalability of our procedure also allows for the analysis of multiple structures (such as an entire protein family) without unreasonable computational expenditure. The successful application of this methodology to known systems serves as a stepping stone towards de novo prediction of interaction sites from any given crystal structure. We identify interaction hotspots across Adenosine Monophosphate-activated Protein Kinase (AMPK) and 3-Phosphoinositide-Dependent Protein Kinase-1 (PDK1), validating the use of our approach across both obligate and non-obligate PPIs. Addition- ally, we analyse Ribulose-1,5-Bisphosphate Carboxylase-Oxygenase (RuBisCO) structures, and show how changes in communication across separate protein subunits and in the cooperativity between active sites depend on the structural composition of the protein complex. Thus, we confirm the functional role played by the small subunits in RuBisCO, and suggest an evolutionary rationale for their existence. Finally, we investigate non-obligate PPIs in G Protein-Coupled Receptors (GPCRs), uncovering extracellular allosteric sites and intracellular protein interaction sites across the Glucagon-Like Peptide 1 (GLP1) receptor and several Class A GPCRs.

These bench-stable fluorine-containing reagents are facile to use and can be prepared in two steps from non-fluorinated heteroaromatic starting materials. The metal-free deoxytrifluoromethylthiolation process using BT-SCF3 proceeds under mild conditions and the similarly efficient trifluoromethylselenylation reactions using BT-SeCF3 are, to the best of our knowledge, the first reported examples of this transformation.

description: Magnetization, heat capacity, electrical resistivity, thermoelectric power, and Hall effect have been investigated on single-crystalline Ce_2PdSi_3. This compound is shown to order antiferromagnetically below N'eel temperature (T_N) \~3 K. The Sommerfeld coefficient far below T_N is found to be about 110 mJ/K^2 mol Ce, which indicates the heavy-fermion character of this compound. The transport and magnetic properties exhibit large anisotropy with an interplay between crystalline-electric-field (CEF) and Kondo effects. The sign of thermoelectric power is opposite for different directions at high temperatures and the ordinary Hall coefficient is anisotropic with opposite sign for different geometries, indicating the anisotropic Fermi surface. The CEF analysis from the temperature dependence of magnetic susceptibility suggests that the ground state is |+/-1/2>. The first and the second excited CEF doublet levels are found to be located at about 30 and 130 K, respectively. The Kondo temperature is estimated to be the same order as T_N, indicating the presence of a delicate competition between the Kondo effect and magnetic order.

description: The dynamical transport properties near the integer quantum Hall transition are investigated at zero temperature by means of the Dirac fermion approach. These properties have been studied experimentally at low frequency omega and low temperature near the nu=1 filling factor Hall transition, with the observation of an anusual broadening and an overall increase of the longitudinal conductivity Re sigma_{xx} as a function of omega. We find in our approach that, unlike for normal metals, the longitudinal conductivity increases as the frequency increases, whilst the width Delta B (or Delta nu) of the conductivity peak near the Hall transition increases. These findings are in reasonable quantitative agreement with recent experiments by Engel et al. as well as with recent numerical work by Avishai and Luck.

description: An anyon exclusion statistics, which generalizes the Bose-Einstein and Fermi-Dirac statistics of bosons and fermions, was proposed by Haldane[1]. The relevant past studies had considered only anyon systems without any physical boundary but boundaries often appear in real-life materials. When fusion of anyons is involved, certain `pseudo-species' anyons appear in the exotic statistical weights of non-Abelian anyon systems; however, the meaning and significance of pseudo-species remains an open problem. In this paper, we propose an extended anyon exclusion statistics on surfaces with gapped boundaries, introducing mutual exclusion statistics between anyons as well as the boundary components. Motivated by Refs. [2, 3], we present a formula for the statistical weight of many-anyon states obeying the proposed statistics. We develop a systematic basis construction for non-Abelian anyons on any Riemann surfaces with gapped boundaries. From the basis construction, we have a standard way to read off a canonical set of statistics parameters and hence write down the extended statistical weight of the anyon system being studied. The basis construction reveals the meaning of pseudo-species. A pseudo-species has different `excitation' modes, each corresponding to an anyon species. The `excitation' modes of pseudo-species corresponds to good quantum numbers of subsystems of a non-Abelian anyon system. This is important because often (e.g., in topological quantum computing) we may be concerned about only the entanglement between such subsystems.

description: Many people living in coastal regions rely on shallow groundwater for their water supply. Seawater flooding after a severe storm or tsunami can damage wells and contaminate the groundwater. This technical note provides advice for rehabilitating wells in such circumstances. It should be used in conjunction with Technical Note 1 which provides general information about rehabilitating wells after a disaster.This is one of a series of four-page highly illustrated notes prepared by WEDC for the World Health Organization to assist those working immediately or shortly after an emergency to plan appropriate responses to the urgent and medium-term water and sanitation needs of affected populations.The notes are relevant to a wide range of emergency situations, including both natural and conflict-induced disasters. They are suitable for field technicians, engineers and hygiene promoters, as well as staff from agency headquarters.Prepared for WHO by WEDC.

description: There are two central models considered in (fault-free synchronous) distributed computing: the CONGEST model, in which communication channels have limited bandwidth, and the LOCAL model, in which communication channels have unlimited bandwidth. Very recently, Le Gall and Magniez (PODC 2018) showed the superiority of quantum distributed computing over classical distributed computing in the CONGEST model. In this work we show the superiority of quantum distributed computing in the LOCAL model: we exhibit a computational task that can be solved in a constant number of rounds in the quantum setting but requires $Ω(n)$ rounds in the classical setting, where $n$ denotes the size of the network.

Autonomous Locomotion Mode Transition in Quadruped Track-Legged Robots: A Simulation-Based Analysis for Step Negotiation

description: Hybrid track/wheel-legged robots combine the advantages of wheel-based and leg-based locomotion, granting adaptability across varied terrains through efficient transitions between rolling and walking modes. However, automating these transitions remains a significant challenge. In this paper, we introduce a method designed for autonomous mode transition in a quadruped hybrid robot with a track/wheel-legged configuration, especially during step negotiation. Our approach hinges on a decision-making mechanism that evaluates the energy efficiency of both locomotion modes using a proposed energy-based criterion. To guarantee a smooth negotiation of steps, we incorporate two climbing gaits designated for the assessment of energy usage in walking locomotion. Simulation results validate the method's effectiveness, showing successful autonomous transitions across steps of diverse heights. Our suggested approach has universal applicability and can be modified to suit other hybrid robots of similar mechanical configuration, provided their locomotion energy performance is studied beforehand.
Gravitational acceleration in a class of geometric sigma models

description: In this work, I examine spherically symmetric solutions in geometric sigma models with four scalar fields. This class of models turns out to be a subclass of the wider class of scalar-vector-tensor theories of gravity. The purpose of the present study is to examine how the additional four degrees of freedom modify Newtonian gravitational acceleration. I have restricted my considerations to pointlike sources in de Sitter background. The resulting gravitational acceleration has the form of a power series, with four major terms standing out. The first and the second are the familiar Newtonian and MOND terms, which dominate at short distances. The third term is dominant at large distances. It is the $Λ$CDM term responsible for the accelerated expansion of the Universe. Finally, the fourth term provides an extra repulsive acceleration that grows exponentially fast with distance. This term becomes significant only at extremely large distances that go beyond the observable Universe. As for the time dependence of the calculated gravitational acceleration, it turns out to have nontrivial, oscillatory character.

Thermodynamics and weak cosmic censorship conjecture in extended phase spaces of anti-de Sitter black holes with particles' absorption

description: The thermodynamics and weak cosmic censorship conjecture in extended phase spaces of charged anti-de Sitter black holes describing the massive gravity are investigated by the absorptions of the scalar particle and fermion. The cosmological constant is seen as a pressure with a conjugate volume. The first law of thermodynamics is recovered. The second law of thermodynamics is violated in the extended phase space of the extremal black hole. For the near-extremal and extremal black holes, the validity of weak cosmic censorship conjecture is tested by evaluating the minimum values of the metric function $f$. It is found that they remain their near-extremity and extremity when the particles are absorbed.

description: Bislang wurde keine Studie durchgeführt, um herauszufinden wie sich die drei Aspekte Attraktivität, Vertrauenswürdigkeit und Expertise von physischen und virtuellen Influencer*innen auf das Brand Image von Unternehmen der Kosmetikbranche in Österreich auswirken. Die Forschungsfrage dazu lautet wie folgt: „Kann das Brand Image eines Unternehmens in der Kosmetikbranche in Österreich durch die Nutzung von virtuellen und/oder physischen Influencer*innen gesteigert werden und welche sind die Gründe hierfür?“. Um die Forschungsfrage zu beantworten, wurde eine quantitative Studie mithilfe einer Online-Umfrage durchgeführt. Für die Analysen der Ergebnisse wurden die Daten von 200 Umfrage-Teilnehmer*innen herangezogen. Diese zeigen, dass ein moderat positiver Zusammenhang zwischen der Attraktivität, Vertrauenswürdigkeit und Expertise von physischen und virtuellen Influencer*innen und dem Brand Image von Unternehmen der Kosmetikbranche in Österreich besteht. Wird somit einer der Aspekte positiver von Nutzer*innen wahrgenommen, so wird auch das Brand Image des Unternehmens in der Kosmetikbranche von den Österreicher*innen positiver wahrgenommen.

Hylaeus leptocephalus

description: Hylaeus leptocephalus (Morawitz, 1870)
 H. leptocephalus est une abeille assez rare. Cette espèce a été signalée en 2015 à Collonges-sous-Salève (France) mais jamais dans le canton de Genève. Elle n’a plus été observée en Suisse romande depuis 1994. Trois individus ont été collectés, sur deux toitures différentes situées en ville de Genève et au Grand-Saconnex. L’espèce est polylectique. Solitaire, elle niche dans des petites cavités dans le sol ou dans des tiges creuses de plantes. Ces types de structure sont particulièrement bien représentés dans le sol des toitures végétalisées où l’espèce a été capturée, avec également la présence d’ Echium vulgare. H. leptocephalus est univoltine et vole de mi-mai à fin septembre. Les trois individ us ont été piégés sur toute la longueur de la période de vol de l’espèce (7.6.–20.6.; 5.7.–18.7.; 16.8.–21.8.).
 Syrphes
 Les trois espèces menacées de syrphes échantillonnées, Cheilosia soror, Eumerus amoenus et Paragus quadrifasciatus, appartiennent au cortège d’espèces connues du canton de Genève et ont été capturées lors de suivis des communautés dans différents contextes (viticole: Pétremand 2012, agricole: Karel 2013 et Surfaces de Promotions de la Biodiversité: De Carvalho & Monod 2014). En considérant les traits écologiques de ces trois espèces menacées, il semble que P. quadrifasciatus soit la seule espèce dont les captures sur une toiture végétalisée ne soient pas dues au hasard. En effet, C. soror et E. amoenus sont typiques de milieux non représentés sur les toitures végétalisées ou faiblement représentés dans les environs des toitures (respectivement forêts alluviales et chênaies thermophiles). Elles sont également spécialistes de familles ou d’espèces végétales non identifiées sur les toitures végétalisées (respectivement ombellifères blanches et Smirnium olusatrum L.).
