Gravity theories with local energy-momentum exchange: a closer look at Rastall-like gravity

description: Einstein's famous equivalence principle is certainly one of the most striking features of the gravitational interaction. In a strict reading, it states that the effects of gravity can be made to disappear $locally$ by a convenient choice of reference frame. As a consequence, no covariantly-defined gravitational force should exist and energy-momentum of all matter and interaction fields combined, with gravity $excluded$, should be locally conserved. Although elegant, this separate conservation law represents a strong constraint on the dynamics of a gravitating system and it is only logical to question its naturality and observational basis. This is the purpose of the present work. For concreteness sake, we analyze, in the context of metric theories of gravity, the simplest phenomenological model which allows for local energy-momentum exchange between the spacetime and matter/interaction fields while preserving the seemingly more natural principle of general covariance. This concrete model turns out to be a generalization of the socalled Rastall's theory, with one important advantage: criticisms made to the latter, which are often used to dismiss it as a viable or interesting model, do not apply to the former in a universe containing "dark" ingredients, such as ours -- a connection which seems to have been overlooked thus far. We conclude by exploring the consequences of our Rastall-like model to standard (astrophysical and cosmological) gravitational scenarios.
description: 21 pages, 11 figures. New version: Title slightly changed; revised (particularly Sec. IV) to make it clearer that the model is not equivalent to Rastall's original theory and how it avoids the criticisms which are used to dismiss the latter

description: Le but du présent travail est d’évaluer dans quelle mesure une tenue vestimentaire (également qualifiée de style ou de look) est une source de conflits pour des élèves. Tenter d’apporter un éclairage sur cette question nécessite l’abord d’un certain nombre de concepts. Ce travail traite premièrement de l’identité, en mentionnant le lien entre ce concept et celui de tenue vestimentaire. L’étude de certains mécanismes de catégorisation et de stéréotypage pousse à l’interrogation des préjugés portant sur des personnes arborant tel ou tel type de look. Le concept d’adolescence permet de mettre en lumière que cette période de vie exacerbe certaines thématiques liées au look. Ainsi l’étude du concept de groupes de pairs pose que les adolescents sont poussés à s’intégrer dans un groupe qui peut être exigeant vis-à-vis du look adopté par l’individu. L’étude de ce concept est aussi l’occasion de noter que le genre des élèves peut avoir une incidence sur la composition de leur groupe de pairs ainsi que sur leur relation au look. Le concept de stigmatisation pose un cadre pour la sélection des indicateurs du rejet, subi notamment à cause d’un look. L’abord de ce dernier concept permet de se positionner sur ses liens avec un terme de sens très proche, le style. C’est aussi l’occasion de postuler une liste de looks compris comme connus des adolescents, dans le but d’interroger la présence de stéréotypes les concernant et d’évaluer l’estime qui est prêtée à chacun dans l’esprit des élèves. Le look est aussi très lié à la thématique des marques, et aux conflits familiaux résultant des coûts exigés par ce type deproduits. La visée du travail est donc d’étudier l’importance particulière du look en lien avec les éléments théoriques précédemment abordés. Optant pour une démarche quantitative, ce travail jauge les différents aspects de la question, en portant sur un nombre suffisant d’élèves pour que les résultats soient traités en tenant compte différents groupes : séparation selon la tranche d’âge, le genre et le look revendiqué des élèves.

description: Identifying the quantum chromodynamics (QCD) color structure of processes provides additional information to enhance the reach for new physics searches at the Large Hadron Collider (LHC). Analyses of QCD color structure in the decay process of a boosted particle have been spotted as information becomes well localized in the limited phase space. While these kind of a boosted jet analyses provide an efficient way to identify a color structure, the constrained phase space reduces the number of available data, resulting in a low significance. In this letter, we provide a simple but a novel data preprocessing method using a Riemann sphere to utilize a full phase space by decorrelating QCD structure from a kinematics. We can achieve a statistical stability by enlarging the size of testable data set with focusing on QCD structure effectively. We demonstrate the power of our method at the finite statistics of the LHC Run 2. Our method is complementary to conventional boosted jet analyses in utilizing QCD information over the wide range of a phase space.

description: Pour ce mémoire, nous avons choisi de travailler sur la relation école-musée dans le cadre d'une visite scolaire au secondaire 1. En nous basant sur les sorties au musée avec les classes, nous voulons bien entendu mettre en avant ce type d'activité dans le cursus scolaire des élèves et plus particulièrement dans notre didactique. Depuis plusieurs années, la place des Arts Visuels à l'école et dans les plans d'études (PER, Plan d'Etude Romand) semble perdre de son importance. La nouvelle réforme des institutions scolaires (LEO) va d'ailleurs dans ce sens avec une volonté de réduire le nombre de périodes attribuées à notre didactique. En tant qu'enseignants d'Arts Visuels, il nous semble important à l'heure actuelle de revaloriser notre didactique en mettant en avant ses qualités, au travers d'activités comme par exemple les visites au musée. En traitant ce sujet, ce qui nous a particulièrement intéressé c'est les possibilités de développement de l'autonomie, de la créativité et de références culturelles chez les élèves plutôt que les acquisitions théoriques et techniques en lien avec notre didactique. Ces notions nous semblent essentielles dans la construction de l'individu et ce type d'activité hors les murs peut permettre leur développement en dehors du cadre habituel qu'est la salle de classe. Ce mémoire établit un certain état des lieux de la situation ainsi qu'une marche à suivre pour comprendre et développer au mieux les relations "école-musée". Tout au long de ce travail nous avons tenté de répondre à la question de recherche énoncée ci-dessus, en nous aidant de nos observations de terrain, ainsi que des données théoriques que nous avons pu récolter.

description: Using the recently installed Gemini Planet Imager (GPI), we have taken the first H-band spectrum of the planetary companion to the nearby young star beta Pictoris. GPI is designed to image and provide low-resolution spectra of Jupiter sized, self-luminous planetary companions around young nearby stars. These observations were taken covering the H-band (1.65 microns). The spectrum has a resolving power of $\sim$ 45 and demonstrates the distinctive triangular shape of a cool substellar object with low surface gravity. Using atmospheric models, we find an effective temperature of $1650 \pm 50$ K and a surface gravity of $\log(g) = 4.0 \pm 0.25$ (cgs units). These values agree well with predictions from planetary evolution models for a gas giant with mass between 10 and 12 $M_{\rm Jup}$ and age between 10 and 20 Myrs.

description: We define a notion of higher order renormalization group equation and investigate when a sequence of trees satisfies such an equation. In the strongest sense, the sequence of trees satisfies a $k$th order renormalization group equation when applying any choice of Feynman rules results in a Green function satisfying a $k$th order renormalization group equation, and we characterize all such sequences of trees. We also make some comments on sequences of trees which require special choices of Feynman rules in order to satisfy a higher order renormalization group equation.

description: Ce travail pose comme élément central la médiation scolaire vaudoise et son fonctionnement. La diversité des difficultés des élèves et la manière dont elles sont traitées constituent la question centrale à ce travail. Comment les médiateurs arrivent-ils à identifier clairement les problèmes des élèves venus en consultation? Le traitement des problèmes des élèves implique-t-il chez les médiateurs des difficultés dans l’établissement des limites à leurs fonctions? Pour répondre au mieux à ces questions, dans ce travail sont présentés différents aspects: la médiation de manière générale, la médiation dans le cadre scolaire et son intérêt, des interviews de médiateurs ainsi que le traitement des résultats. L’analyse de ces résultats démontre que, même si elle ne constitue pas un problème majeur, l’identification des difficultés des élèves et leur traitement constituent toutefois une difficulté pour les médiateurs. Une difficulté tout d’abord dans l’aide apportée aux élèves mais aussi dans la définition de leur rôle. Les réponses des médiateurs démontrent également que différentsprojets et améliorations pourraient être mis en place. Ce travail mène donc à une réflexion sur la fonction des médiateurs, leurs relations avec les élèves et les moyens d’aborder leurs problèmes. Il met en avant certaines des difficultés auxquelles ils peuvent être confrontés et des suggestions d’améliorations possibles.

Factors Influencing Consultation Length in General Practice

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: General practice, the foundation of Australia’s healthcare system, provides care and essential healthcare services to patients as well as acting as gatekeepers to vital secondary medical services. A standard GP consultation of 10-15 minutes. This imposes time constraints on the consultation, that could be a limit for patients with several presenting concerns or a complicated concern. This limitation could compel GPs to compromise on the quality of care either by inadequately addressing patient’s concerns by prioritising time or by frequently extending consultations and running late. While longer GP consultations have been identified as beneficial in the existing literature, how consultation length relates to the internal factors (problems presented in the consultation) and external factors (social and economic factors) has not been studied. Using 41- video-recorded GP consultations and interdisciplinary approaches (conversation analysis and economic analysis), this thesis studies how external and internal factors within a GP’s consultations relate to consultation length, by studying: i) How do external factors relate to how and when medical concerns are raised? ii) How do internal factors affect the consultation length? iii) What is the pattern of raising medical concerns during a GP consultation? The results suggest external factors and internal factors affect GP consultation length. Specifically, older patients (35-64 years-old & 65-85+years-old) had shorter consultations, while patients with tertiary education had shorter consultation length. Agenda setting was rarely seen in GP consultation; however, we find it does shorten consultation length. GP driven consultation resulted in shorter consultation length. The results from this thesis emphasise that future policy aimed at improving health care access needs to account for the characteristics of GP consultation along with its length.

description: To secure computer infrastructure, we need to configure all security-relevant settings. We need security experts to identify security-relevant settings, but this process is time-consuming and expensive. Our proposed solution uses state-of-the-art natural language processing to classify settings as security-relevant based on their description. Our evaluation shows that our trained classifiers do not perform well enough to replace the human security experts but can help them classify the settings. By publishing our labeled data sets and the code of our trained model, we want to help security experts analyze configuration settings and enable further research in this area.

description: La décennie de l’éducation en vue du développement durable a lancé en Suisse, comme dans de nombreux autres pays, une discussion concernant l’intégration possible de l’éducation en vue du développement durable (EDD) dans le système scolaire. Cette approche pédagogique étant encore relativement jeune, diverses études ont été menées pour définir ses principes et des formes de concrétisation possibles. Bien que la plupart des réflexions en cours puissent s’appliquer à divers niveaux scolaires, seules quelques études sur l’intégration de l’EDD au secondaire II ont été menées. Le présent mémoire se propose poursuivre la discussion à ce niveau en analysant sous l’angle de l’EDD un projet d’enseignement/apprentissage de géographie effectué sur une année dans deux classes d’option complémentaire au gymnase. Le présent travail tentera de répondre aux questions suivantes : Un enseignement correspondant aux principes d’une EDD est-il possible au secondaire II-gymnase ? En quoi la géographie se prête-t-elle à un enseignement de ce type ? Quelles sont les conditions nécessaires pour qu’une EDD puisse être mise en œuvre dans le cadre de l’enseignement de la géographie ? Quelles sont les questions ouvertes à clarifier? Il en est ressorti que le projet d’enseignement/apprentissage étudié permet la concrétisation d’une EDD au secondaire II et que la géographie se prête bien à ce type de démarche. La combinaison de la pédagogie du projet et d’une éducation par les pairs articulée autour d’une sensibilisation au DD a constitué une approche intéressante, pouvant inspirer d’autres travaux. Les conditions permettant la réalisation du projet sont néanmoins exigeantes, ce qui pose la question de la reproductibilité de ce type de projet, et mène à une série de questions ouvertes discutées à la fin du travail.

description: We complete the study of static BPS, asymptotically AdS$_4$ black holes within N=2 FI-gauged supergravity and where the scalar manifold is a homogeneous very special Kahler manifold. We find the analytic form for the general solution to the BPS equations, the horizon appears as a double root of a particular quartic polynomial whereas in previous work this quartic polynomial further factored into a pair of double roots. A new and distinguishing feature of our solutions is that the phase of the supersymmetry parameter varies throughout the black hole. The general solution has $2n_v$ independent parameters; there are two algebraic constraints on $2n_v+2$ charges, matching our previous analysis on BPS solutions of the form $AdS_2\times Σ_g$. As a consequence we have proved that every BPS geometry of this form can arise as the horizon geometry of a BPS AdS$_4$ black hole. When specialized to the STU-model our solutions uplift to M-theory and describe a stack of M2-branes wrapped on a Riemman surface in a Calabi-Yau fivefold with internal angular momentum.

description: We start a general study of counting the number of occurrences of ordered patterns in words generated by morphisms. We consider certain patterns with gaps (classical patterns) and those with no gaps (consecutive patterns). Occurrences of the patterns are known, in the literature, as rises, descents, (non-)inversions, squares and p-repetitions. We give recurrence formulas in the general case, then deducing exact formulas for particular families of morphisms. Many (classical or new) examples are given illustrating the techniques and showing their interest.

description: Fibre optic technology connects the world through the Internet, enables remote sensing, and connects disparate functional optical devices. Highly confined silicon photonics promises extreme scale and functional integration. However, the optical modes of silicon nanowire waveguides and optical fibres are very different, making efficient fibre-chip coupling a challenge. Vertical grating couplers, the dominant coupling method today, have limited optical bandwidth and are naturally out-of-plane. Here we demonstrate a new method that is low-loss, broadband, easily manufacturable, and naturally planar. We adiabatically couple a tapering silicon nanowire waveguide to a conic nanotapered optical fibre, measuring transmission between 2.0 and 2.2 micron wavelength. The silicon chip is fabricated at a commercial foundry and then post-processed to release the tapering nanowires. We estimate an optimal per-coupler transmission of -0.48 dB (maximum; 95% confidence interval [+0.46, -1.68] dB) and a 1-dB bandwidth of 295 nm . With automated measurements, we quantify the device tolerance to lateral misalignment, measuring a flat response within +/- 0.968 micron. This design can enable low-loss modular systems of integrated photonics irrespective of material and waveband.

description: Cette étude s’intéresse aux jeunes adolescents suisses et américains et plus particulièrement aux jeunes du canton de Vaud et de l’Etat de Californie. Pour cela, un protocole commun a été établi dans le cadre d’un projet PEERS impliquant des étudiants de l’université de Humboldt en Californie et des Etudiants de la HEP Vaud. Un test de condition physique et des questionnaires mesurant le stylede vie, lescompétences physiques perçues et les motivations sportives des élèves suisses et américains ont été effectués. Cette recherchevise à comparer la performance d’élèves américains et suisses dans l’exécution d’un test de condition physique (FITNESGRAM). Une fois cette comparaison effectuée, il s’agira de déterminer les facteurs influençant le résultat comme, le style de vie, la sédentarité, la nutrition ou encore les programmes scolaires. Ces facteurs seront déterminants pour analyser les résultats des tests. Ce document concerne la partie théorique qui consiste en une revue de littérature. Dans un premier temps, il est question de la santé des jeunes et des recommandations en matière d’activité physique qui leur sont proposées dans les deux pays touchés par cette étude. La revue de littérature suggère un minimum de 60 minutes d’activités par jour. Par la suite, les styles de vie des Américains et des Suisses sontcomparés. Les facteurs que sont la sédentarité, l’activité physique, la nourriture et la condition physique des jeunes sont passés en revue afin d’en retirer les principales différences. Les précédentes études relèvent peu de différences entre les deux populations de cette recherche même si les Suisses mangent de façon un peu plus équilibrée que les américains. Il faut toutefois souligner que les études comparatives avec des protocoles identiques sont rares voire inexistantes entre ces deux pays, d’où l’intérêt de cette recherche. Enfin, les programmes scolaires d’éducation physique ont été comparés. Les résultats sont semblables en ce qui concerne le programme, par contre la mise en application de ces programmes diffère. En effet, peu d’écoles californiennes suivent les recommandations en matière d’éducation physique, principalement par manque d’argent ce qui n’est pas le cas en Suisse.

description: We provide conclusive experimental evidence that zero bias anomaly in the differential resistance of magnetic tunnel junctions (MTJs) is due to electron-electron interaction (EEI), clarifying a long standing issue. Magnon effect that caused confusion is now excluded by measuring at low temperatures down to 0.2 K and with reduced AC measurement voltages down to 0.06 mV. The normalized change of conductance is proportional to $\ln{(eV/k_{B}T)}$, consistent with the Altshuler-Aronov theory of tunneling that describes the reduction of density of states due to EEI, but inconsistent with magnetic impurity scattering. The slope of the $\ln{(eV/k_{B}T)}$ dependence is symmetry dependent: the slopes for P and AP states are different for coherent tunnel junctions with symmetry filtering, while nearly the same for those without symmetry filtering (amorphous barriers). This observation may be helpful for verifying symmetry preserved filtering in search of new coherent tunneling junctions, and for probing and separating electron Bloch states of different symmetries in other correlated systems.

title: Attrition of mid-career teachers in a neoliberal world – why are experienced teachers leaving the profession?
Creators: name: Bilton, Mary
Publisher: name: University of Reading
Year: 2023

description: There is an international recruitment and retention crisis in teaching, yet there is an imbalance in research addressing why mid-career teachers are continuing to leave the profession prior to normal retirement age. Research and Government policy in the UK focuses on the retention of new and beginning teachers and overlooks the phenomenon of attrition of those with years of experience and expertise. This research was located in the interpretive paradigm and used an embedded mixed-methodology to gather data by conducting an online questionnaire (n=119) and subsequent semi-structured interviews with mid-career secondary school teachers (n=14). Thematic analysis was used to scrutinize the data from the interviews. Through the lens of Labour Process Theory it was possible to shed light on how mid-career teachers perceive their work to be conceptualised by Government and school leadership teams and exposed how their labour is utilized and managed. In doing so, it has been possible to gain a deeper understanding of how mid-career teachers position themselves in their profession and how this impacts their connection with the four key concepts of workload, stress, career and professional identity. Findings suggest that mid-career teachers feel dissatisfied with their work: a diminished sense of professional identity, lack of autonomy, limited opportunities to develop their career, lack of respect for their experience, and the pressure of being under surveillance which in turn, contributes to increased levels of dissatisfaction with their work. Crucially, participants shed light on the concept of ‘workload’ in a more nuanced way than simply hours worked or tasks 4 | P a g e undertaken. By re-framing the concept of workload, it is possible to acknowledge the role that senior leaders can play in the attrition of mid-career teachers. The concluding proposals to reform and reconceptualise the work teachers undertake (by reducing the gap between hierarchical decision making and the subordinate teacher), suggest that attrition could be reduced by giving teachers more autonomy and control over key aspects of their working lives. Furthermore, through a cessation of conceptualising experienced teachers as workers whose labour and often ‘surplus labour’ is owned by stakeholders, mid-career teachers could enjoy a longer and more manageable career in the profession.

description: Construction of any kind of knowledge organization system starts from the fundamental building blocks, which are concepts. Once a representative set of concepts has been chosen and each one clearly defined, their hierarchical relationships can be established. Fundamental facets emerge from these hierarchies. In a post-coordinate scheme, such as a thesaurus, associative relationships between concepts in different facets can be defined. In a pre-coordinate scheme, such as a classification, concepts from two or more facets can also be combined, following rules of citation order, to express compound subjects. Citation order has to take account of the role which each concept plays in the compound as well as the facet to which it belongs, and these roles and facet names should be explicitly shown in schedules to distinguish such combinations from hierarchical subordination. The first-cited facet need not be discipline, or field of activity, but can, for example, be “things” or “phenomena”.
 Hierarchies which are not based on genus-species relationships need special consideration; whole-part relationships, for example, are best restricted to concepts which are individual instances rather than classes.

description: Acceleration sensors built into smartphones, i-pads or tablets can conveniently be used in the Physics laboratory. By virtue of the equivalence principle, a sensor fixed in a non-inertial reference frame cannot discern between a gravitational field and an accelerated system. Accordingly, acceleration values read by these sensors must be corrected for the gravitational component. A physical pendulum was studied by way of example, and absolute acceleration and rotation angle values were derived from the measurements made by the accelerometer and gyroscope. Results were corroborated by comparison with those obtained by video analysis. The limitations of different smartphone sensors are discussed.

description: In ferroelectrics, complex interactions among various degrees of freedom enable the condensation of topologically protected polarization textures. Known as ferroelectric solitons, these particle-like structures represent a new class of materials with promise for beyond CMOS technologies due to their ultrafine size and sensitivity to external stimuli. Such polarization textures have scarcely been reported in multiferroics. Here, we report a range of soliton topologies in bismuth ferrite strontium titanate superlattices. High-resolution piezoresponse force microscopy and Cs-corrected high-angle annular dark-field scanning transmission electron microscopy reveal a zoo of topologies, and polarization displacement mapping of planar specimens reveals center-convergent and divergent topological defects as small as 3 nm. Phase field simulations verify that some of these topologies can be classed as bimerons, with a topological charge of plus and minus one, and first-principles-based effective Hamiltonian computations show that the co-existence of such structures can lead to non-integer topological charges, a first observation in a BiFeO3-based system. Our results open new opportunities in multiferroic topotronics.

description: Sous quelle(s) forme(s) peut-on dispenser une sensibilisation aux médias ? Comment articuler l'enseignement des arts visuels avec cette problématique ? Quels exemples existent, et desquels nous inspirer ? Quels moyens, et quelles conditions, existent plus précisément dans le canton de Vaud ? Quelle posture pédagogique pourrait-on mobiliser pour sensibiliser les jeunes à la culture médiatique ? Quels moyens peut-on mobiliser pour atteindre cette fin ? Et enfin, quelle nécessité ou quels avantages, pourrions-nous tirer de la mise en place d’ateliers de ce genre pour comprendre le réel ? Quoique vastes, ces questions posent le cadre de réflexion sur un fait de société qui occupe notre présent. Elles orientent et nourrissent la proposition pédagogique d'une didactique possible du cinéma. Ainsi, développons-nous quelques observations d'ordre sociologique sur la diffusion et la réception contemporaine des médias. Nous considérons ensuite l'histoire du cinéma où nous abordons la genèse de pratiques cinématographiques initiées par les avant-gardes historiques avec la focalisation sur le (re-)montage comme lieu privilégié d'une pratique critique. Dès lors, nous envisageons la possibilité d'une didactique se concentrant sur des savoirs-esthétiques et des savoirs-pratiques en développant un scénario de cours et d'ateliers. Nous examinons les conditions de possibilité de cet enseignement, proposons des pistes à suivre et analyserons diverses modalités de sa mise en place.

Too Many, Too Few, or Just Right? The Predicted Number and Distribution of Milky Way Dwarf Galaxies

description: We predict the spatial distribution and number of Milky Way dwarf galaxies to be discovered in the DES and LSST surveys, by completeness correcting the observed SDSS dwarf population. We apply most massive in the past, earliest forming, and earliest infall toy models to a set of dark matter-only simulated Milky Way/M31 halo pairs from Exploring the Local Volume In Simulations (ELVIS). The observed spatial distribution of Milky Way dwarfs in the LSST-era will discriminate between the earliest infall and other simplified models for how dwarf galaxies populate dark matter subhalos. Inclusive of all toy models and simulations, at 90% confidence we predict a total of 37-114 L $\gtrsim 10^3$L$_{\odot}$ dwarfs and 131-782 L $\lesssim 10^3$L$_{\odot}$ dwarfs within 300 kpc. These numbers of L $\gtrsim 10^3$L$_{\odot}$ dwarfs are dramatically lower than previous predictions, owing primarily to our use of updated detection limits and the decreasing number of SDSS dwarfs discovered per sky area. For an effective $r_{\rm limit}$ of 25.8 mag, we predict: 3-13 L $\gtrsim 10^3$L$_{\odot}$ and 9-99 L $\lesssim 10^3$L$_{\odot}$ dwarfs for DES, and 18-53 L $\gtrsim 10^3$L$_{\odot}$ and 53-307 L $\lesssim 10^3$L$_{\odot}$ dwarfs for LSST. These enormous predicted ranges ensure a coming decade of near-field excitement with these next generation surveys.

description: El uso del acolchado en suelo para producir hortalizas incrementa el rendimiento y la calidad de los productos cosechados, sin embargo, estos incrementos se encuentran condicionados al tipo de acolchado, ya sea plástico u orgánico. Se realizó un experimento en el cultivo de repollo (Brassica oleracea L. var. capitata) durante la temporada de 2021-2022, con el objetivo de evaluar su respuesta sobre la eficiencia en el uso del agua, nutrición mineral y rendimiento a cuatro tipos de acolchados en suelo. Se evaluaron cuatro tratamientos (suelo con acolchado plástico color negro, color blanco, acolchado con paja de trigo y un control sin acolchar) distribuidos bajo un diseño de bloques al azar con cuatro repeticiones. Los resultados mostraron que el acolchado plástico blanco incrementó la biomasa total, el peso del repollo y peso de las hojas, en comparación al resto de los tratamientos. El uso de ambos acolchados plásticos (blanco y negro) incrementó la concentración de nitratos en el extracto celular de la nervadura central. La temperatura foliar incrementó solo por el uso del acolchado plástico negro. Finalmente, la eficiencia en el uso del agua resultó mayor en los tratamientos con acolchado plástico y menor en el suelo sin acolchar. Considerando la mayor eficiencia en el uso del agua, rendimiento y nutrición mineral se concluyó que el suelo con acolchado plástico (blanco o negro) es el más recomendable para producir repollo en el valle de Mexicali, México.

description: An outstanding challenge in large-scale quantum platforms is to simultaneously achieve strong interactions, giving rise to the most interesting behaviors, and local addressing -that can probe them. In the context of correlated phases, local addressing enables one to directly probe the nature of the system's order. Meanwhile, for out-ofequilibrium dynamics, such addressing allows the study of quantum information spreading and operator growth. Here, we introduce a novel technique that enables the measurement of local correlation functions, down to single-site resolution, despite access to only global controls. Our approach leverages the intrinsic disorder present in a solid-state spin ensemble to dephase the nonlocal components of the correlation function. Utilizing this toolset, we measure both the spin and energy transport in nuclear spin chains. By tuning the interaction Hamiltonian via Floquet engineering, we investigate the cross-over between ballistic and diffusive hydrodynamics. Interestingly, when the system is both interacting and (nearly-)integrable, we observe the coexistence of diffusive spin transport with ballistic energy transport.

description: Northamptonshire Archaeology, 10, 31-93
description: Remains of an extensive complex (6000+ sq m) of Iron Age enclosures and associated features were excavated in advance of quarrying. Work was focused on the intact Enclosure B and its internal features, and on three adjacent hut-circles. At least 180 pits were found, of which half lay within Enclosure B; seven articulated burials (three human, two pig and two dog) were recovered from the pits, and there was some evidence for grain storage. Many recuts of the main enclosure ditches indicate long occupation, perhaps 4th to early 1st century BC. Pottery, small finds and human and animal bones are catalogued.

description: The standard Bayesian technique for searching pulsar timing data for gravitational wave (GW) bursts with memory (BWMs) using Markov Chain Monte Carlo (MCMC) sampling is very computationally expensive to perform. In this paper, we explain the implementation of an efficient Bayesian technique for searching for BWMs. This technique makes use of the fact that the signal model for Earth-term BWMs (BWMs passing over the Earth) is fully factorizable. We estimate that this implementation reduces the computational complexity by a factor of 100. We also demonstrate that this technique gives upper limits consistent with published results using the standard Bayesian technique, and may be used to perform all of the same analyses that standard MCMC techniques can perform.
