SignificanceWhether sympatric speciation (SS) is rare or common is still debated. Two populations of the spiny mouse,Acomys cahirinus, from Evolution Canyon I (EC I) in Israel have been depicted earlier as speciating sympatrically by molecular markers and transcriptome. Here, we investigated SS both genomically and methylomically, demonstrating that the opposite populations of spiny mice are sister taxa and split from the common ancestor around 20,000 years ago without an allopatric history. Mate choice, olfactory receptors, and speciation genes contributed to prezygotic/postzygotic reproductive isolation. The two populations showed different methylation patterns, facilitating adaptation to their local environment. They cope with abiotic and biotic stresses, due to high solar interslope radiation differences. We conclude that our new genomic and methylomic data substantiated SS.
Marking statements of fact in early pidgins
Authors: Versteegh Kees 
Published: March 2022

Abstract
The particle fi is used in Classical Arabic as a local and temporal preposition, ‘in’. In the
contemporary Arabic dialects, it has the same meaning, but in addition it is used in some dialects as an existential, ‘there
is/are’. In a number of Arabic work-related pidgins, such as Gulf Pidgin Arabic and Pidgin Madame, fi has
acquired new functions. It does not only denote nominal predication, location, and possession, but is also used in combination
with verbal forms. Several proposals have been made to explain this use of fī. Avram (2012) regards fī as a progressive aspect marker, while Potsdam & Alanazi (2014) deny the verbal nature of the construction and regard fī as
a copula. Bakir (2014) analyzes fī as a marker of verbality of the
predicate. The present paper suggests that the general function of fi is to mark the link between topic and focus
as assertive rather than modal and looks for parallels of this use in a few other work-related pidgins.
Succès ou échec?

Résumé
Cet article se propose de reconnaître le chemin suivi par les traités zoologiques d’Aristote dans le monde latin. Michel Scot était le premier à les rendre accessibles en version latine. Environ quarante ans plus tard, Guillaume de Moerbeke a entrepris le même travail, pour laquelle il s’est directement basé sur le grec. Bien que les deux versions aient connu un succès considérable à en juger par le nombre de manuscrits conservés, les voies par lesquelles ces derniers ont été répandus étaient bien distinctes et dépendaient d’événements plus ou moins contingents ou ciblés. Cependant, une autre version latine médiévale des Parties des animaux d’Aristote, dont le traducteur est probablement Barthelémy de Messine, a à peine survécu. Il semble possible que la traduction ait fait partie d’une entreprise beaucoup plus ambitieuse.
Deux siècles plus tard, deux traducteurs latins se sont concurrencés sur le domaine de la zoologie aristotélicienne. La traduction de Georges Trapezuntius a connu une diffusion respectable en forme manuscrite, mais elle n’a guère influencé l’histoire intellectuelle. En revanche, la version latine de Théodore Gaza a immédiatement conquis les presses émergentes et le goût des savants.1
“Fuchs und Rabe”

Abstrakt
Fabeln haben sich im Laufe der Jahrhunderte und in unterschiedlichen kulturellen Kontexten kontinuierlich
gewandelt. Sie erfahren neue Bedeutungen und neue Verwendungen, indem sie den gesellschaftlichen Gegebenheiten der Zeit angepasst
werden. Die genauere Untersuchung von Zeichnungen, Karikaturen und Cartoons bezogen auf bestimmte Fabeln erwiesen sich dabei
häufig als instruktiv. So hat auch die Untersuchung einiger Cartoons aus iranischen Medien bezüglich der Fabel “Rabe und Fuchs” zu
interessanten Resultaten geführt, zumal es oft bei solchen Bildern kaum einer Erklärung bedarf, um die Bedeutung des Gemeinten
ebenso in einem anderen kulturellen Kontext zu verstehen.
Entre savoir livresque et observation vécue
Authors: Meyers Jean 
Published: March 2022

Résumé
Comme dans presque toute la littérature du Moyen Âge, l’animal chez Fabri est le plus souvent considéré comme
objet de connaissance, indépendamment de toute tonalité affective, et intervient comme instrument du sens. L’animal, réel ou
imaginaire, peut donc être décrit d’après le miroir déformant de l’érudition livresque de l’auteur, comme c’est le cas dans la
description de l’unicorne, du pélican ou du phénix. Il peut aussi être décrit par souci documentaire ou par goût pour les
mirabilia, qu’il s’agisse de surprendre le lecteur et de satisfaire sa curiosité ou de fournir des
renseignements pratiques. C’est le cas dans l’évocation, avant le départ pour le Sinaï, des ânes et des chameaux, animaux mieux
adaptés à la traversée du désert que les chevaux. Le goût pour les animaux inconnus et les mirabilia explique
aussi la description des crocodiles et hippopotames, de la civette, du léopard, des autruches, perroquets, girafes, lions, ours et
singes, tout comme celle de monstres imaginaires, tel le Troyp, sorte de licorne de mer qui perfore les navires.
Il y a cependant aussi chez Fabri plusieurs passages dans lesquels l’auteur parle des animaux avec un attachement affectif évident
ou dans lesquels il les utilise comme ressort narratif.
Tradition classique, transmission du savoir professionnel et expérience de visu dans la Mascalcia de Dino Dini
Authors: Vitale-Brovarone Alessandro 
Published: March 2022

Résumé
Dino Dini, vétérinaire actif à Florence au XIVe siècle, laisse dans sa Mascalcia un précieux témoignage des rapports entre les textes classiques, les sources contemporaines et l’expérience personnelle. L’attention de l’auteur pour la morphologie des races de chevaux (en particulier les chevaux de la Sardaigne) met en valeur ses talents d’observateur direct de la nature, qui se manifeste aussi dans des nouvelles techniques médicales et chirurgicales, et dans une très fine attention pour l’animal en tant que personne.
Communication of radiation risk from imaging studies: an IAEA-coordinated international survey

Published: March 2022

Abstract
The purpose of this IAEA-coordinated international study was to understand aspects related to the communication of radiation risk from imaging studies, such as how often imaging department personnel and referring physicians are asked about radiation risks in diagnostic imaging, who asks about these risks, how often professionals are able to provide satisfactory answers using qualitative metrics and how often quantitative risk estimates are needed. A web-based questionnaire with ten questions was completed by 386 healthcare professionals from 63 countries from all four continents, including clinicians/referring physicians (42.5%), radiologists or nuclear medicine physicians (26.7%), medical physicists (23.1%), radiographers/radiological technologists (6.2%) and others (1.6%). The results indicate that radiation risk-related questions are largely asked by patients (73.1%) and parents of child patients (38.6%), and 78% of the professionals believe they are able to answer those questions using qualitative metrics such as very small/minimal, small, medium rather than number of cancers likely occurring. The vast majority, with over three times higher frequency, indicated the purpose of knowing previous radiological exams as ‘both clinical information and radiation exposure history’ rather than ‘only clinical information’. Nearly two-thirds of the clinicians/referring physicians indicated that knowing the radiation exposure history of the patient will affect their decision-making for the next exam, as against only about one-fifth who said ‘no, it will not affect their decision-making’. The same question, when addressed to radiologists, resulted in a slightly larger fraction of about three-quarters who said ‘yes’, as opposed to a smaller fraction of about 12% who said ‘no, it will not affect their decision-making’. Mapping the present situation of communication of benefits and risks for patients is important and may be the basis of further analysis, regular monitoring and possibly a target for clinical audits. Further studies focused on specific professional groups might help in obtaining á deeper understanding of the need for practical communication tools.

Published: March 2022

AbstractObjective. A linear relationship between impedance change (ΔZ) measured by thoracic electrical impedance tomography (EIT) and tidal volume (VT) has been demonstrated. This study evaluated the agreement between the displayed VT calculated by the EIT software (VTEIT) and spirometry (VTSPIRO) after an indirect two-point calibration.Approach.The EIT software was programmed to execute a bedside two-point calibration from the subject-specific, linear equation defining the relationship between ΔZand VTSPIROand displaying VTEITbreath-by-breath in 20 neutered male, juvenile pigs. After EIT calibration VTs of 8, 12, 16 and 20 ml kg−1were applied to the lungs. VTEITand VTSPIROwere recorded and analysed using Bland–Altman plot for multiple subject measurements. Volumetric capnography (VCap) and spirometry data were explored as components of variance using multiple regression.Main results.A mean relative difference (bias) of 0.7% with 95% confidence interval (CI) of −10.4% to 10.7% were found between VTEITand VTSPIROfor the analysed data set. The variance in VTEITcould not be explained by any of the measured VCap or spirometry variables.Significance.The narrow CI estimated in this study allows the conclusion that EIT and its software can be used to measure and accurately convert ΔZinto mililitre VT at the bedside after applying an indirect two-point calibration.

Abstract
Grid inefficiency (GI) correction is critically important to
accurately determine the energy and emission angle of charged
particles in Frisch grid ionization chambers (FGIC). Presently,
three correction methods have been proposed in the literature. All
these three methods rely strongly on the accurate and stable
calibration between two different electrical chain gains in
experiments. To avoid these challenges, they are firstly
investigated with Monte Carlo method by using Garfield and SRIM
toolkit. Two types of grid wire (diameter 90 and 180 μm) were
simulated to investigate the impacts of GI correction on energy
correction, and ten different emission angles were adopted to
estimate the effects of these correction methods on the angle
reconstruction. The simulation results clearly distinguished the
differences among these correction methods in energy
determination. The correlation analysis (R = 0.99) among these
different correction methods indicated that the impact of either
correction approach is small on the determination of emission
angle. The present work firstly investigates the effects of GI
correction on emission angle with Monte Carlo methods, which is the
basis of future work to measure the total kinetic energy and mass
distribution of Fission Fragment (FF).

Abstract
The High-Intensity Heavy Ion Accelerator Facility (HIAF), proposed by the Institute of Modern Physics, Chinese Academy of Sciences (IMP), is being designed to provide primary and radioactive intense beams for nuclear and related research. As an important part of HIAF, the Booster Ring (BRing) is a fast ramping synchrotron and is used to obtain high intensity (238U35+, 1 × 1011 ppp) and high energy (0.835 GeV/u) heavy-ion beam. Moreover, the beam rigidity of the Booster Ring varies widely from 1 Tm to 34 Tm. These require the dipole of Booster Ring to have a large-good field region, a high magnetic field homogeneity, and a wide range of magnetic field variation from 0.047 T to 1.58 T. Aiming at the properties of the dipole magnet, we adopt some new methods to improve magnetic field precision and optimize efficiency. Double symmetrical air holes in the magnet pole are used to guarantee the magnetic field homogeneity under a wide magnetic field range. At the same time, the linear programming algorithm is adopted to optimize the integral magnetic field uniformity of the iron-dominated dipole magnet, which improves the integral magnetic field precision and optimization efficiency. So far, the prototype dipole magnet has been fabricated and tested. Through magnetic field optimization, measurement, and secondary trimming, the measurement results satisfy the physical requirements.
Modelling neural entrainment and its persistence: influence of frequency of stimulation and phase at the stimulus offset
Authors: Otero Mónica , Lea-Carnall Caroline , Prado Pavel , Escobar María-José , El-Deredy Wael 
Published: March 2022

Abstract
Neural entrainment, the synchronization of brain oscillations to the frequency of an external stimuli, is a key mechanism that shapes perceptual and cognitive processes. Objective. Using simulations, we investigated the dynamics of neural entrainment, particularly the period following the end of the stimulation, since the persistence (reverberation) of neural entrainment may condition future sensory representations based on predictions about stimulus rhythmicity. Methods. Neural entrainment was assessed using a modified Jansen-Rit neural mass model (NMM) of coupled cortical columns, in which the spectral features of the output resembled that of the electroencephalogram (EEG). We evaluated spectro-temporal features of entrainment as a function of the stimulation frequency, the resonant frequency of the neural populations comprising the NMM, and the coupling strength between cortical columns. Furthermore, we tested if the entrainment persistence depended on the phase of the EEG-like oscillation at the time the stimulus ended. Main Results. The entrainment of the column that received the stimulation was maximum when the frequency of the entrainer was within a narrow range around the resonant frequency of the column. When this occurred, entrainment persisted for several cycles after the stimulus terminated, and the propagation of the entrainment to other columns was facilitated. Propagation also depended on the resonant frequency of the second column, and the coupling strength between columns. The duration of the persistence of the entrainment depended on the phase of the neural oscillation at the time the entrainer terminated, such that falling phases (from π/2 to 3π/2 in a sine function) led to longer persistence than rising phases (from 0 to π/2 and 3π/2 to 2π). Significance. The study bridges between models of neural oscillations and empirical electrophysiology, providing insights to the mechanisms underlying neural entrainment and the use of rhythmic sensory stimulation for neuroenhancement.

Abstract
The status of nickelate superconductors in relation to cuprate high temperature superconductors is one of the concepts being discussed in high temperature superconductivity in correlated transition metal oxides. New additions to the class of infinite layer nickelates can provide essential input relating to connections or distinctions. A recently synthesized compound Ba2NiO2(AgSe)2, which contains isolated ‘infinite layer’ NiO2 planes, may lead to new insights. Our investigations have discovered that, at density functional theory mean field level, the ground state consists of an unusual

e

g

singlet on the Ni2+ ion arising from large but separate Mott insulating gaps in both

e

g

orbitals, but with different, anti-Hund’s, spin directions of their moments. This textured singlet incorporates at the least new physics, and potentially a new platform for nickelate superconductivity, which might be of an unconventional form for transition metal oxides due to the unconventional undoped state. We include in this paper a comparison of electronic structure parameters of Ba2NiO2(AgSe)2 with a better characterized infinite layer nickelate LaNiO2. We provide more analysis of the d
8 anti-Hund’s singlet that emerges in this compound, and consider a minimally correlated wavefunction for this singlet in an itinerant background, and begin discussion of excitations—real or virtual—that may figure into new electronic phases.

Abstract

Background
The brain is one of the main target organs affected by hypertension. Impaired cerebral oxygenation during exercise is an indicator of cerebral dysfunction. We aimed to investigate whether cerebral oxygenation during exercise correlates with subclinical markers of early target organ damage in a population of middle-aged, newly diagnosed hypertensive and healthy individuals.

Methods
Carotid intima–media thickness (cIMT) was measured using ultrasound, arterial stiffness was estimated measuring the augmentation index and pulse wave velocity, and retinal vessel diameter was assessed via the central retinal-arteriolar and vein equivalent and retinal-arteriovenous ratio. Participants (n = 93) performed a 3-minute isometric handgrip exercise. Cerebral prefrontal oxygenation was measured continuously using near infrared spectroscopy. The average exercise responses in oxygenated hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), and total hemoglobin (tHb) were assessed. Univariate analyses were performed; partial correlation was used to account for traditional cardiovascular risk factors to identify independent associations between cerebral-oxygenation indices and early markers of target organ damage.

Results
Mean cIMT was negatively correlated with the average exercise response in cerebral oxygenation (rhoO2Hb = −0.348, PO2Hb = 0.001; rhotHb = −0.253, Pthb = 0.02). Augmentation index was negatively correlated with cerebral oxygenation during exercise (rhoO2Hb = −0.374, P &lt; 0.001; rhotHb = −0.332, P = 0.02), whereas no significant correlation was observed between pulse wave velocity and cerebral-oxygenation indices. In the adjusted analysis, cerebral oxygenation was correlated with central retinal arteriolar diameter (CRAE r = 0.233, P = 0.043).

Conclusions
Our novel findings suggest that indices of lower cerebral oxygenation during a submaximal physical task are associated with markers of early, subclinical target organ damage, namely increased cIMT, arterial stiffness, and arteriolar retinal narrowing in newly diagnosed, untreated, hypertensive individuals.
BSDE: barycenter single-cell differential expression for case–control studies
Authors: Zhang Mengqi , Guo F Richard 
Published: March 2022

Abstract

Motivation
Single-cell sequencing brings about a revolutionarily high resolution for finding differentially expressed genes (DEGs) by disentangling highly heterogeneous cell tissues. Yet, such analysis is so far mostly focused on comparing between different cell types from the same individual. As single-cell sequencing becomes cheaper and easier to use, an increasing number of datasets from case–control studies are becoming available, which call for new methods for identifying differential expressions between case and control individuals.

Results
To bridge this gap, we propose barycenter single-cell differential expression (BSDE), a nonparametric method for finding DEGs for case–control studies. Through the use of optimal transportation for aggregating distributions and computing their distances, our method overcomes the restrictive parametric assumptions imposed by standard mixed-effect-modeling approaches. Through simulations, we show that BSDE can accurately detect a variety of differential expressions while maintaining the type-I error at a prescribed level. Further, 1345 and 1568 cell type-specific DEGs are identified by BSDE from datasets on pulmonary fibrosis and multiple sclerosis, among which the top findings are supported by previous results from the literature.

Availability and implementation
R package BSDE is freely available from doi.org/10.5281/zenodo.6332254. For real data analysis with the R package, see doi.org/10.5281/zenodo.6332566.
