description: Motivated by the triumph and limitation of graphene for electronic applications, atomically thin layers of group VI transition metal dichalcogenides are attracting extensive interest as a class of graphene-like semiconductors with a desired band-gap in the visible frequency range. The monolayers feature a valence band spin splitting with opposite sign in the two valleys located at corners of 1st Brillouin zone. This spin-valley coupling, particularly pronounced in tungsten dichalcogenides, can benefit potential spintronics and valleytronics with the important consequences of spin-valley interplay and the suppression of spin and valley relaxations. Here we report the first optical studies of WS2 and WSe2 monolayers and multilayers. The efficiency of second harmonic generation shows a dramatic even-odd oscillation with the number of layers, consistent with the presence (absence) of inversion symmetry in even-layer (odd-layer). Photoluminescence (PL) measurements show the crossover from an indirect band gap semiconductor at mutilayers to a direct-gap one at monolayers. The PL spectra and first-principle calculations consistently reveal a spin-valley coupling of 0.4 eV which suppresses interlayer hopping and manifests as a thickness independent splitting pattern at valence band edge near K points. This giant spin-valley coupling, together with the valley dependent physical properties, may lead to rich possibilities for manipulating spin and valley degrees of freedom in these atomically thin 2D materials.

description: We consider the warped AdS(6)xS^4/Z_n backgrounds dual to certain 5d quiver gauge theories. By studying dual giant gravitons in the AdS(6) geometry we are able to partially probe the Higgs branch of these theories. We show how the quantization of the phase space of such dual giants coincides with the counting of holomorphic functions on C^2/Z_n, which is the geometric part of the Higgs branch for these theories.

description: Traditional email encryption schemes are vulnerable to EFail attacks, which exploit the lack of message authentication by manipulating ciphertexts and exfiltrating plaintext via HTML backchannels. Swiss Post's IncaMail, a secure email service for transmitting legally binding, encrypted, and verifiable emails, counters EFail attacks using an authenticated-encryption with associated data (AEAD) encryption scheme to ensure message privacy and authentication between servers. IncaMail relies on a trusted infrastructure backend and encrypts messages per user policy. This paper presents a revised IncaMail architecture that offloads the majority of cryptographic operations to clients, offering benefits such as reduced computational load and energy footprint, relaxed trust assumptions, and per-message encryption key policies. Our proof-of-concept prototype and benchmarks demonstrate the robustness of the proposed scheme, with client-side WebAssembly-based cryptographic operations yielding significant performance improvements (up to ~14x) over conventional JavaScript implementations.

description: Magnetic Resonance Imaging has become nowadays an indispensable tool with applications ranging from medicine to material science. However, so far the physical limits of the maximum achievable experimental contrast were unknown. We introduce an approach based on principles of optimal control theory to explore these physical limits, providing a benchmark for numerically optimized robust pulse sequences which can take into account experimental imperfections. This approach is demonstrated experimentally using a model system of two spatially separated liquids corresponding to blood in its oxygenated and deoxygenated forms.

description: We investigate theoretically the momentum-dependent frequency and damping of low-lying collective excitations of superconductors and charged superfluids in the BCS-BEC crossover regime. The study is based on the Gaussian pair-and-density fluctuation method for the propagator of Gaussian fluctuations of the pair and density fields. Eigenfrequencies and damping rates are determined in a mutually consistent nonperturbative way as complex poles of the fluctuation propagator. Particular attention is paid to new features with respect to preceding theoretical studies, which were devoted to collective excitations of superconductors in the far BCS regime. We find that at a sufficiently strong coupling, new branches of collective excitations appear, which manifest different behavior as functions of the momentum and the temperature.

Apoyado, a su vez, en una revisión documental de indicadores de gestión en los servicios de Clínica Médica Sectores de Varones y Mujeres del Hospital Dr Arturo Oñativia. Se registró un predominio de población joven, muchos de ellos con internaciones previas en el servicio; más de la mitad cuenta con cobertura social; se obtuvo una percepción positiva en la atención de enfermería, ubicándola en una escala de evaluación entre medio y alto. Se comprobó la relación entre la buena percepción de satisfacción de los pacientes y los cuidados de enfermería en las escalas analizadas, excepto en la de “Accesibilidad”, que no depende del liderazgo de enfermería. Sin embargo, hay algunos indicadores que se deben mejorar en el servicio, dado que las respuestas fueron de carácter indeterminado y para obtener una calificación de excelencia se debe elevar el nivel de satisfacción de los pacientes.

description: We show that photon number measurement can be used to detect superfluidity for a two-band Bose-Hubbard model coupled to a cavity field. The atom-photon coupling induces transitions between the two internal atomic levels and results in entangled polaritonic states. In the presence of a cavity field, we find different photon numbers in the Mott-insulating versus superfluid phases, providing a method of distinguishing the atomic phases by photon counting. Furthermore, we examine the dynamics of the photon field after a rapid quench to zero atomic hopping by increasing the well depth. We find a robust correlation between the field's quench dynamics and the initial superfluid order parameter, thereby providing a novel and accurate method of determining the order parameter.

description: With the growing “beautification” and development of Chicago neighborhoods, many communities in the north and west sides have begun to lose their people and identity. This analysis aims to understand how Chicago’s community-based organizations, CBOs, within Logan Square and Pilsen have attempted to combat the effects of gentrification on their neighborhoods. This topic is important to consider in order to understand how different organizations have approached the issues of displacement and identity-loss and what efforts they have made in order to mitigate, combat, or reverse them. By utilizing a mixed-methods approach, I find that the role of a CBO is to provide residents with goods and services they cannot get otherwise, keeping residents informed on the on-goings of their neighborhoods, and creating a space where residents can not only express their opinions on those changes but also learn how to best navigate around them. Thus, it is recommended that local governments work closer with CBOs in order to support their work and to gain a deeper understanding of the concerns of the residents.

description: Context: Both the absolute mass-loss rates and the mechanisms that drive the mass loss of late-type supergiants are still not well known. Binaries such as alpha Sco provide the most detailed empirical information about the winds of these stars. Aims: The goal was to improve the binary technique for the determination of the mass-loss rate of alpha Sco A by including a realistic density distribution and velocity field from hydrodynamic and plasma simulations. Methods: We performed 3D hydrodynamic simulations of the circumstellar envelope of alpha Sco in combination with plasma simulations accounting for the heating, ionization, and excitation of the wind by the radiation of alpha Sco B. These simulations served as the basis for an examination of circumstellar absorption lines in the spectrum of alpha Sco B as well as of emission lines from the Antares nebula. Results: The present model of the extended envelope of alpha Sco reproduces some of the structures that were observed in the circumstellar absorption lines in the spectrum of alpha Sco B. Our theoretical density and velocity distributions of the outflow deviate considerably from a spherically expanding model, which was used in previous studies. This results in a higher mass-loss rate of (2 +/- 0.5) x 10^-6 M_sun/yr. The hot H II region around the secondary star induces an additional acceleration of the wind at large distances from the primary, which is seen in absorption lines of Ti II and Cr II at -30 km/s.

Publisher: name: MDPI
Year: 2023

description: Accumulating solar and/or environmental heat in walls of apartment buildings or houses is a way to level-out daily temperature differences and significantly cut back on energy demands. A possible way to achieve this goal is by developing advanced composites that consist of porous cementitious materials with embedded phase change materials (PCMs) that have the potential to accumulate or liberate heat energy during a chemical phase change from liquid to solid, or vice versa. This paper aims to report the current state of art on numerical and theoretical approaches available in the scientific literature for modelling the thermal behavior and heat accumulation/liberation of PCMs employed in cement-based composites. The work focuses on reviewing numerical tools for modelling phase change problems while emphasizing the so-called Stefan problem, or particularly, on the numerical techniques available for solving it. In this research field, it is the fixed grid method that is the most commonly and practically applied approach. After this, a discussion on the modelling procedures available for schematizing cementitious composites with embedded PCMs is reported.

description: [abridged] Energy relaxation around a massive black hole (MBH) is key to establishing the dynamical state of galactic nuclei, and the nature of close stellar interactions with the MBH. The standard description of relaxation as diffusion provides a perturbative 2nd-order solution in the weak two-body interaction limit. We run N-body simulations and find that this solution fails to describe the non-Gaussian relaxation on short timescale, which is strongly influenced by extreme events even in the weak limit, and is thus difficult to characterize and measure. We derive a non-perturbative solution for relaxation as an anomalous diffusion process, and develop a robust estimation technique to measure it in simulations. These enable us to analyze and model our numerical results, and validate in detail, for the first time, this model of energy relaxation around an MBH on all timescales. We derive the relation between the energy diffusion time, t_E, and the time for a small perturbation to return to steady state, t_r, in a relaxed, single mass cusp around a MBH. We constrain the contribution of strong encounters, measure that of the weakest encounters, determine the value of the Coulomb logarithm, and provide a robust analytical estimate for t_E in a finite nuclear stellar cusp. We find that t_r ~ 10t_E ~(5/32)Q^2P_h/N_h log Q, where Q=M_bh/M_* is the MBH to star mass ratio, the orbital period P_h and number of stars N_h are evaluated at the energy scale corresponding to the MBH's sphere of influence, E_h=sigma_inf^2, where sigma_inf is the velocity dispersion far from the MBH. We conclude, using the observed cosmic M_bh/sigma correlation, that cusps around lower-mass MBHs (M_bh<10^7 Mo), which evolved passively over a Hubble time, should be relaxed. We consider the effects of anomalous energy diffusion on orbital perturbations of stars observed near the Galactic MBH.

Pero a la hora de hablar de cómo hacer ese proceso para llegar a los resultados deseados surge una amplia gama de posibilidades tanto de teorías y estilos de liderazgo como de teorías de motivación. Objetivo: Analizar si el jefe de enfermería de un servicio de internación de pediatría de un hospital público del conurbano bonaerense puede ser un líder positivo que motiva al personal a su cargo. Diseño Metodológico: Este trabajo de investigación corresponde a un estudio descriptivo, cuantitativo, prospectivo y de corte transversal. Realizado en un hospital público del conurbano bonaerense entre el 05 de junio y el 12 de junio de 2021. Dirigido a determinar la situación de las variables en una población. Se ha tomado como población en estudio al 100% de los enfermeros del servicio de internación de pediatría de un hospital público bonaerense, según planilla de personal del servicio: 25 enfermeros. Conclusiones: En base a los resultados relevados puede indicarse que hay elementos de que el jefe del servicio estudiado tiene características de líder positivo que motiva al personal a su cargo. Aunque no puede asegurarse que eso es así en un ciento por ciento por algunos valores contradictorios y otros que indican falta de constancia. Por ejemplo, de los tres aspectos analizados respecto de la motivación, se observa que siempre llama al personal pero no es constante al compartirle información sobre los resultados de producción; el 41% de la población respondió que sucede “a veces”. Y es muy poco el incentivo que realiza sobre capacitación, siendo éste un elemento no financiero muy valorado por el personal de salud.

description: We use the LoopSim and VBFNLO packages to investigate a merged sample of partonic events that is accurate at NLO in QCD simultaneously for the WZ and WZ+jet production processes. In certain regions of phase space such a procedure is expected to account for the dominant part of the NNLO QCD corrections to the WZ production process. For a number of commonly used experimental observables, we find that these corrections are substantial, in the 30-100% range, and in some cases their inclusion can reduce scale uncertainties by a factor of two. As in the underlying VBFNLO calculations, we include the leptonic decays of the vector bosons and all off-shell and finite-width effects.

description: Local community organizations are important to the formation of neighborhood cohesion and social capital. However, neighborhood cohesion in racially integrated communities can be difficult to form and maintain, and it remains unclear how local community organizations can best promote interracial social engagement in racially diverse communities. This report looks at Chicago community areas that have recently achieved racial integration: Beverly and Irving Park. Using ethnographic data and semistructured interviews with organization leaders, the data in this report implies best practices for organizations wishing to form a sense of community, outlines barriers to social integration that organizations face, and offers potential solutions to overcome these barriers. This report concludes with policy implications and recommendations for community organizations, and ultimately analyzes how Beverly and Irving Park community organizations assist and promote the process of social integration in their community areas.

These frequency corrections can be pre-computed based on measured energy density spectra, and therefore come at no additional computational cost compared to linear theory. The nonlinear forecasting methodology is tested on highly-nonlinear, synthetically generated seas with a variety of values of average steepness and directional spreading, and shown to consistently outperform a linear forecast.

description: Through the McDonald Observatory M Dwarf Planet Search, we have acquired nearly 3,000 high-resolution spectra of 93 late-type (K5-M5) stars over more than a decade using HET/HRS. This sample provides a unique opportunity to investigate the occurrence of long-term stellar activity cycles for low-mass stars. In this paper, we examine the stellar activity of our targets as reflected in the H-alpha feature. We have identified periodic signals for 6 stars, with periods ranging from days to more than 10 years, and find long-term trends for 7 others. Stellar cycles with P > 1 year are present for at least 5% of our targets. Additionally, we present an analysis of the time-averaged activity levels of our sample, and search for correlations with other stellar properties. In particular, we find that more massive, earlier type (M0-M2) stars tend to be more active than later type dwarfs. Furthermore, high-metallicity stars tend to be more active at a given stellar mass. We also evaluate H-alpha variability as a tracer of activity-induced radial velocity (RV) variation. For the M dwarf GJ 1170, H-alpha variation reveals stellar activity patterns matching those seen in the RVs, mimicking the signal of a giant planet, and we find evidence that the previously identified stellar activity cycle of GJ 581 may be responsible for the recently retracted planet f (Vogt et al. 2012) in that system. In general, though, we find that H-alpha is not frequently correlated with RV at the precision (typically 6-7 m/s) of our measurements.

Appropriate Nouns with Obligatory Modifiers

Year: 2012
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: The notion of appropriate sequence as introduced by Z. Harris provides a powerful syntactic way of analysing the detailed meaning of various sentences, including ambiguous ones. In an adjectival sentence like 'The leather was yellow', the introduction of an appropriate noun, here 'colour', specifies which quality the adjective describes. In some other adjectival sentences with an appropriate noun, that noun plays the same part as 'colour' and seems to be relevant to the description of the adjective. These appropriate nouns can usually be used in elementary sentences like 'The leather had some colour', but in many cases they have a more or less obligatory modifier. For example, you can hardly mention that an object has a colour without qualifying that colour at all. About 300 French nouns are appropriate in at least one adjectival sentence and have an obligatory modifier. They enter in a number of sentence structures related by several syntactic transformations. The appropriateness of the noun and the fact that the modifier is obligatory are reflected in these transformations. The description of these syntactic phenomena provides a basis for a classification of these nouns. It also concerns the lexical properties of thousands of predicative adjectives, and in particular the relations between the sentence without the noun : 'The leather was yellow' and the adjectival sentence with the noun : 'The colour of the leather was yellow'.

description: Transmission over multiple frequency bands combined into one logical channel speeds up data transfer for wireless networks. On the other hand, the allocation of multiple channels to a single user decreases the probability of finding a free logical channel for new connections, which may result in a network-wide throughput loss. While this relationship has been studied experimentally, especially in the WLAN configuration, little is known on how to analytically model such phenomena. With the advent of Opportunistic Spectrum Access (OSA) networks, it is even more important to understand the circumstances in which it is beneficial to bond channels occupied by primary users with dynamic duty cycle patterns. In this paper we propose an analytical framework which allows the investigation of the average channel throughput at the medium access control layer for OSA networks with channel bonding enabled. We show that channel bonding is generally beneficial, though the extent of the benefits depend on the features of the OSA network, including OSA network size and the total number of channels available for bonding. In addition, we show that performance benefits can be realized by adaptively changing the number of bonded channels depending on network conditions. Finally, we evaluate channel bonding considering physical layer constraints, i.e. throughput reduction compared to the theoretical throughput of a single virtual channel due to a transmission power limit for any bonding size.

description: Today in the city of Chicago, there are many violence prevention organizations. My qualitative research, gathered through key informant interviews, allows me to categorize these organizations into two groups, retributive and restorative, to analyze their respective success. While retributive organizations may appear to succeed in the short term, their methods compound problems of violence, rendering their results antithetical to their mission. In comparison, restorative organizations align in a process centered on reducing violence by helping the individual. I recommend that traditionally retributive organizations adopt characteristics of restorative organizations in order to better prevent violence in Chicago both in the short-term and in the long-term.

description: En este trabajo se analizaron los avances del liderazgo de Enfermería en la transformación de Maternidad Tradicional a Maternidad Segura y Centrada en la Familia en el Hospital Dr. Joaquín Castellanos, Departamento General Güemes, Salta. Con un diseño de investigación cualitativa, no experimental, descriptiva y documental, longitudinal desde 2017 y con una perspectiva intercultural. Apoyada en una revisión documental de los informes técnicos de la evaluación por el Ministerio de la Provincia de Salta y UNICEF Argentina, tomando como herramienta el Manual de Prácticas para iniciar el camino hacia el cumplimiento de los objetivos estratégicos de la iniciativa. Se realizaron entrevistas individuales, focales, y encuestas de opinión. No hay testimonio escrito sobre los acuerdos políticos tripartitos en la implementación del modelo. Se concluye que falta un proyecto bien definido por etapas estructuradas, se percibe insuficiente adherencia a las capacitaciones propuestas desde la interculturalidad, dificultades en la comunicación entre profesionales, y entre los servicios de maternidad y neonatología para la unificación de criterios de trabajo. El personal de enfermería es de grado profesional y se reconoce su liderazgo en la adecuación de servicios prenatales, parto y salas de internación; no siendo así en educación durante las visitas de maternidad. Los cambios edilicios, así como la Residencia para Madres, se basaron en reformas estructurales, pero no cumplen con los requisitos indicados. Se trabaja en el programa de lactancia materna y COPAP (Contacto Piel a Piel). A pesar de las dificultades encontradas se evidencia una clara dirección hacia la implementación del programa.

description: We examine the real-time dynamics of a system of one or more black holes interacting with long wavelength gravitational fields. We find that the (classical) renormalizability of the effective field theory that describes this system necessitates the introduction of a time dependent mass counterterm, and consequently the mass parameter must be promoted to a dynamical degree of freedom. To track the time evolution of this dynamical mass, we compute the expectation value of the energy-momentum tensor within the in-in formalism, and fix the time dependence by imposing energy-momentum conservation. Mass renormalization induces logarithmic ultraviolet divergences at quadratic order in the gravitational coupling, leading to a new time-dependent renormalization group (RG) equation for the mass parameter. We solve this RG equation and use the result to predict heretofore unknown high order logarithms in the energy distribution of gravitational radiation emitted from the system.

description: The Fenna-Matthews-Olson (FMO) complex is a photosynthetic pigment-protein complex that has been the subject of study of decades of research, both experimental and theoretical. The FMO complex is small enough that computational modeling is feasible, while the rich excitonic interactions between the pigments give rise to absorption and circulardichroism (CD) spectra with many interesting details. This makes FMO an excellent testing ground for new predictive modeling techniques.
 In this work we model the FMO complex from first-principles, wherein the only input is the X-ray crystal structure of the protein. We compute steady-state absorption and CD spectra of wild-type (WT) FMO as well as two mutants, Y16F and Q198V, in which amino acid residues near pigment 3 and pigment 7 are replaced respectively. CD spectra contain extra structural information and thus provide another avenue of investigation into the electronic properties of the FMO complex. We find that while there are large structural changes in the mutants, not all of the structural changes produce significant spectral changes. We conclude that the primary contributor to the spectral changes in Y16F is the breaking of a hydrogen bond between the nearby tyrosine and pigment 3. On the other hand, the spectral changes in Q198V are due to a collection of effects cancelling one another out to varying degrees, all induced by widespread structural changes as a result of the mutation.
 We then perform time-resolved absorption and CD spectroscopy measurements on WT, Y16F, and Q198V FMO to provide a high quality set of experimental data against which the first-principles spectra can be validated. We find that in order to accurately model the triplet energy transfer dynamics in FMO two effects must be accounted for in the modeling: (1) the Stark shift caused by the rotation of the bacteriochlorophyll’s permanent dipole moment upon entering a triplet state, and (2) decays must be modeled as Boltzmann populations rather than individual pigments.

description: Ultra-reliable and low-latency communication has received significant research attention. A key part of this evolution are the Time-Sensitive Networking (TSN) standards, which extend Ethernet with real-time mechanisms. To guarantee high reliability, the standard IEEE 802.1CB-2017 Frame Replication and Elimination for Reliability enables redundant communication over disjoint paths. While this mechanism is essential for time-critical applications, the standard contains some fundamental limitations that can compromise safety. Although some of these limitations have been addressed, none of the previous works provide solutions to these problems. This paper presents solutions to four main limitations of the IEEE 802.1CB-2017 standard. These are 1) choosing match versus vector recovery algorithm, 2) defining the length of the sequence history, 3) setting a timer to reset the sequence history, and 4) dimensioning the burst size in case of link failures. We show how these challenges can be solved by using best- and worst-case path delays of the network. We have performed simulations to illustrate the impact of the limitations and prove the correctness of our solutions. Thereby, we demonstrate how our solutions can improve reliability in TSN networks and propose these methods as guidance for users of the IEEE 802.1CB standard.

description: VEGAS (Varying Evolvability-Guided Adaptive Search) is a new methodology proposed to deal with the neutrality property of some optimization problems. ts main feature is to consider the whole neutral network rather than an arbitrary solution. Moreover, VEGAS is designed to escape from plateaus based on the evolvability of solution and a multi-armed bandit. Experiments are conducted on NK-landscapes with neutrality. Results show the importance of considering the whole neutral network and of guiding the search cleverly. The impact of the level of neutrality and of the exploration-exploitation trade-off are deeply analyzed.

description: El objetivo de este estudio es describir evidencias del comportamiento del liderazgo de Enfermería en la Estrategia de Renovación de la Atención Primaria de la Salud en el Área Operativa XXII del Hospital Dr. Joaquín Castellanos, Departamento General Güemes, Salta, 2020. Es una investigación no experimental, descriptiva, observacional, focalizada en variables de corte transversal en mayo de 2020. Fundamentado en el instrumento cuantitativo de la OPS “Renovación de la APS”. A través del proceso de observación, una revisión documental del Análisis de Situación de Salud del área en cuestión y la aplicación de cuestionarios individuales, se pretende confirmar la hipótesis “El Liderazgo de Enfermería en abordaje de los elementos esenciales de la salud condiciona cambios en cierta medida en la estrategia para la renovación de la APS en el área Operativa”. Se obtiene que en las variables Barreras de acceso, Mecanismos activos de participación, Organización y gestiones óptimas, Primer contacto, Recursos humanos apropiados y Recursos adecuados y sostenibles se cumple la hipótesis de trabajo. Mientras que en las variables Acción integral e integrada, Atención apropiada, Políticas y programas proequidad y Acciones intersectoriales no se observa esa relación. Se evidencian deficiencias en el programa de estudio de pregrado de enfermería comunitaria y dificultades de integración entre agentes sanitarios/enfermería. Se sugiere hacer hincapié en el desarrollo de la enfermería de práctica avanzada, aplicada a la atención primaria; rever las variables donde el liderazgo de enfermería no es eficiente y mejorar el programa de estudio pregrado con adecuaciones específicas vigentes en APS.
