Neuroimaging Correlates of Depression—Implications to Clinical Practice

The growth of the literature about neuroimaging of major depressive disorder (MDD) over the last several decades has contributed to the progress in recognizing precise brain areas, networks, and neurotransmitter processes related to depression. However, there are still doubts about the etiology and pathophysiology of depression that need answering. The authors did a nonsystematic review of the literature using PubMed database, with the following search terms: “major depressive disorder,” “neuroimaging,” “functional imaging,” “magnetic resonance imaging,” “functional magnetic resonance imaging,” and “structural imaging,” being selected the significant articles published on the topic. Anterior cingulate cortex, hippocampus, orbitomedial prefrontal cortex, amygdala basal ganglia, and the cerebellum were the main affected areas across the selected studies. These areas respond to particular neurotransmitter systems, neurochemicals, hormones, and other signal proteins; even more, the evidence supports a distorted frontolimbic mood regulatory pathway in MDD patients. Despite the positive findings, translation to treatment of MDD remains illusory. In conclusion, this article aims to be a critical review of the neuroimaging correlates of depression in clinical research with the purpose to improve clinical practice.
Model Predictive Control of the Open-winding PMSG System Based on Three-Dimensional Reference Voltage-Vector

For the open-winding permanent-magnet synchronous generator system with a common dc bus, in order to improve the steady-state control performance of conventional prediction control and simultaneously reduce the calculation burden, a zero-sequence current suppression method based on the prediction of three-dimensional reference voltage is proposed in this article. First, the voltage vector used by prediction control is extended from the plane to the three-dimensional (3-D) space. The voltage vectors of two converters are analyzed and predicted under the 3-D space. Moreover, to improve steady-state performance, two voltage vectors are applied in one control period, and the voltage selection principle that determines candidate vectors is presented. Finally, experimental results test the effectiveness of this method.
The Structure and Function of Heavy Syllables in the Phonology of English Language

Abstract This paper examines the place of heavy syllables in relation to syllable structure in English language. Drawing from examples in the literature, it is seen that syllable weight plays a vital role in the placement of stress in English. It is noted that although nouns, adjectives and verbs display different stress patterns, in all of these, it is always the heavy syllables that attract stress. Apart from the issue of stress assignment, the paper looks at other prosodic phenomena in which syllable weight is paramount. These include metrical scansion, compensatory lengthening, language acquisition and the syllable weight in tone languages. All of these indicate the indispensability of heavy syllables in the prosody of human languages.
The Role of Interaction in Language Evolution. Evidence from Two Iterated Learning Experiments with Human Participants

Abstract. Experiments conducted with the use of the iterated learning methodology have recently become a rich source of information on the hypothetic ways in which the human language might have evolved. Basing on the groundbreaking studies of the Language Evolution and Computation Centre in Edinburgh, it is possible to utilise the methodology in question in increasingly more advanced experiments, both with and without human participants, using various designs and referring to different theories. The present paper discusses the role of interaction in iterated learning experiments, comparing the results obtained in two studies: the first one conducted with only one participant at a time (without communication) and the second one with three participants interacting with each other. As results suggest, the intuition that communication constitutes one of key factors in language evolution might be misleading.
Twenty‐Five Years of Lower Tropospheric Ozone Observations in Tropical East Asia: The Influence of Emissions and Weather Patterns

Tropospheric ozone affects the Earth's radiative balance, oxidative capacity, and air quality, yet the long‐term ozone trend in East Asia and its driver(s) remain poorly understood. Here we present ozone measurements obtained during 1994–2018 on China's southern coast. The measurement location intercepts China's outflow most of the time and the inflow of tropical maritime air during summer. We found an overall increase in the ozone level (0.35 ppbv/year), and the increase occurred mainly during the first half of the 25‐year period but appeared to level off in recent years in Chinese outflow. Large ozone increase (~20% per decade) was found in the maritime air. Model simulations show that recent weather conditions have reduced maritime ozone, counteracting the impact of the growing Southeast Asia's emissions. Our results fill the gap in the long‐term ozone trend in Asia and highlight the complex interaction of weather and emissions in driving the ozone change.
Patients traités pour une tuberculose active: étude rétrospective de 4 ans d'activité du Centre antituberculeux, Service de Pneumologie, Genève

Ce travail analyse les caracteristiques cliniques et sociales des patients traites pour une tuberculose (TB) active ainsi que le taux de succes therapeutique dans une region (Geneve) a faible incidence de tuberculose, mais avec un taux eleve d'immigration. L'examen retrospectif des dossiers de 252 patients suivis au Centre antituberculeux de Geneve (HUG) pour une TB active entre 1999 et 2003 a mis en evidence une proportion elevee de patients immigres (84% dont 25% de requerants d'asile) refletant la tendance actuelle dans la plupart des pays d'Europe occidentale. Nous avons egalement pu montrer qu'il y avait dans cette casuistique une proportion elevee de co-infection avec le VIH (11%), y compris dans la population jeune autochtone. L'evolution des patients traites etait favorable dans 87% des cas en se referant aux criteres OMS, ce qui est au-dessus de la moyenne europeenne et repond aux objectifs de l'OMS.
How the presentation and metadata of a news article influences perceptions of fake news

Fake news refers to content that is intentionally fake but that looks and feels like real news. The term has been used politically to discredit specific news articles, stories, or publishers. This is an in-progress quasi-experimental study that examines whether the appearance of metadata and how a news article document is styled influences different perceptions of a news article as fake news among participants with different political persuasions. The study could make important contributions to information literacy research and make a theoretical contribution to the role that documents play in political information.
Free Field Realisations in Logarithmic Conformal Field Theory

Invariances of conformal field theories (CFTs) would seem to suggest that correlation functions behave as power laws. However, logarithms also exhibit conformal invariance. When logarithms are permitted in two-dimensional CFTs, the corresponding state spaces characteristically involve reducible but indecomposable Virasoro modules with non-diagonalisable algebra action. Notably, such state spaces no longer naturally admit a grading into energy eigenspaces. Despite this non-diagonalisable energy operator, one finds significant physical motivation for the study of such representations, with many interesting statistical mechanical models exhibiting this behaviour: percolation, dilute polymers, self-avoiding walks, and more. A vast amount of effort has been made in the study of these two-dimensional logarithmic CFTs, both their internal structure and their fusion rules. However, it would be fair to say that logarithmic CFTs are still less well understood than their non-logarithmic counterparts. In recent years, the relevance of free-field oscillator algebras to the study of such representations has become more and more apparent. Many of the module structures in question might more appropriately be considered as Fock-type spaces. In this thesis we develop free field realisations of logarithmic CFTs. We analyse some general features, examining staggered modules of the Virasoro algebra in particular, before providing a construction for staggered modules consisting of Fock spaces considered as Virasoro modules. We derive an explicit formula for a module invariant of staggered Fock modules, verifying that the given construction agrees with those seen to date in the literature. We then turn to more conjectural areas, examining how the non-diagonalisaiblity of the Virasoro representation can be reproduced by the inclusion of additional modes into the underlying oscillator algebras, and how the states created by these modes correspond to the vacuum evaluations of logarithmic fields. We take these as our motivating examples for a subsequent working definition of logarithmic vertex operator algebras, in the hope that not only do their state spaces correspond to the staggered structures developed to this point, but that they provide an additional avenue of approach in the construction and study of logarithmic conformal field theories.
“Peace Is Not a Free Gift”: Indigenous Conceptions of Peace among the Guji-Oromo in Southern Ethiopia

ABSTRACT:Indigenous African knowledge of building and maintaining peace is not well known and has not been much used in the dominant modern mechanisms of conflict resolution. With the aim of addressing this limitation, this article analyzes the broader conceptualization of peace and peace building among the Guji-Oromo in southern Ethiopia. The Guji-Oromo are keenly aware that their existence as a society depends on the maintenance of peace (nagaa) among them as a community and between them and God as well as between them and their natural and human environments. They believe that peace is not a free gift, because maintaining it requires continuous and earnest negotiation, social actions, and cooperation among many stakeholders who possess political, cultural, and spiritual powers. The article further argues that the Guji-Oromo conceptualize peace beyond the conventional understandings that position it as the absence of conflict or warfare. Rather, for the Guji, peace is broadly understood as a continuous flow of relationships between the people and their human and nonhuman environments. The article shows that Guji’s conceptions of peace are not static; rather, they are subject to internal and external influences that shape how different members of the society conceptualize it and the way it is maintained.
Electroacupuncture-induced release of cholecystokinin octapeptide mediated by spinal μ- and к-opioid receptors

Cholecystokinin octapeptide (CCK-8) in CNS has been shown to function as aneuropeptide with the most potent anti-opioid activity. It facilitates opioid tolerance andelectroacupuncture (EA) tolerance. Our previous study suggested that morphineadministration and EA stimulation can produce a marked increase of the CCK-8immunoreactivity (ir) in the perfusate of rat spinal cord. However, the problems are

Risk for Compassion Fatigue Among Doctor of Nursing Practice Students

Background/Objectives: Compassion fatigue (CF) is severe emotional and physical exhaustion resulting from unresolved burnout and/or secondary traumatic stress. Prevalent in registered nurses and physicians, CF negatively impacts both the caregiver and the care provided and is associated with job attrition. There is no direct measure for CF. Risk is assigned according to the intensity of each constituent part and the relationships between these parts. The purpose of this practice inquiry was to describe the risk for CF among doctor of nursing practice (DNP) students seeking nurse practitioner certification, a previously unstudied and potentially at-risk population. Design: A descriptive study was performed to describe: 1) the prevalence of compassion satisfaction; 2) the prevalence of burnout; 3) the prevalence of secondary traumatic stress; 4) the prevalence of risk profiles developed by Stamm (2010); and 5) the relationship between demographic characteristics and CF risk profiles in a sample of DNP students. Setting: The University of Arizona, College of Nursing between August 24, 2013 and November 19, 2013. Participants: 59 graduate nursing students seeking nurse practitioner certification and a DNP degree self-selected to participate in the study. Measurements: The Professional Quality of Life Scale-5 (ProQOL 5) was utilized to measure the components of CF: compassion satisfaction, burnout, and secondary traumatic stress. Patient demographics included: gender, age, years in nursing, nursing specialty, and employment status. Results: The DNP student population appears to be at-risk for CF, with 69% of the sample falling outside of the “low risk” CF profile. Stamm’s (2010) five risk profiles were expanded to assign a level of risk to the 63% of participants who did not land in an existing profile. There were no statistically significant relationships between demographic variables and the expanded
A Task-Oriented User Selection Incentive Mechanism in Edge-Aided Mobile Crowdsensing

The designs of existing incentive mechanisms in mobile crowdsensing (MCS) are primarily platform-centered or user-centered, while overlooking the multidimensional consideration of sensing task requirements. Therefore, the user selection fails to effectively address the task requirements or the relevant maximization and diversification problems. To tackle these issues, in this paper, with the aid of edge computing, we propose a task-oriented user selection incentive mechanism (TRIM), in an effort toward a task-centered design framework in MCS. Initially, an edge node is deployed to publish the sensing task according to its requirements, and constructs a task vector from multiple dimensions to maximize the satisfaction of the task requirements. Meanwhile, a sensing user constructs a user vector to formalize the personalized preferences for participating in the task response. Furthermore, by introducing a privacy-preserving cosine similarity computing protocol, the similarity level between the task vector and the user vector can be calculated, and subsequently a target user candidate set can be obtained according to the similarity level. In addition, considering the constraint of the task budget, the edge node performs a secondary sensing user selection based on the ratio of the similarity level and the expected reward of the sensing user. By designing a secure multi-party sorting protocol, enhanced by fuzzy closeness and the fuzzy comprehensive evaluation method, the target user set is determined aiming at maximizing the similarity of the task requirements and the user's preferences, while minimizing the payment of the edge node, and ensuring the fairness of the sensing user being selected. The simulation results show that TRIM achieves feasible and efficient user selection while ensuring the privacy and security of the sensing user in MCS. Among the dynamic changes of task requirements, TRIM excels with user selections reaching nearly 90% on the data quality level compliance rate and 70% on the task budget consumption ratio, superior to the other incentive mechanisms.

A autenticacao de dispositivos e o controle de acesso aos recursos disponiveis na rede e um dos atuais desafios em IoT. Neste sentido, e essencial que exista um modelo de gestao de identidades para IoT que contemple as caracteristicas especificas deste contexto, especialmente quando consideramos as restricoes computacionais dos dispositivos e sua potencial mobilidade entre dominios. Como solucao para este problema e proposto o FLAT, um protocolo de autenticacao federada para IoT. FLAT associa: o uso de apenas criptografia simetrica no Cliente, a substituicao de criptossistemas tradicionais como o RSA/DSA por criptossistemas equivalentes baseados em curvas elipticas, e o uso de certificados implicitos. O dispositivo Cliente no FLAT e mais eficiente do que a solucao baseline em total de dados trocados e em tempo de computacao. FLAT tambem e capaz de reduzir o total de dados transmitidos em cerca de 31% em relacao a solucao baseline, sendo uma alternativa leve para autenticacao em IoT.
Inteligência artificial adaptativa para ajuste dinâmico de dificuldade em jogos digitais

O Ajuste Dinâmico de Dificuldade (DDA) consiste em uma alternativa para o balanceamento estatico de dificuldade realizado nos jogos digitais. Esta abordagem tem se mostrado apropriada para proporcionar desafios equilibrados, evitando tedio e/ou frustracao durante o jogo. Assim, o objetivo deste trabalho e apresentar um mecanismo que realize o DDA durante uma partida de um jogo MOBA. A ideia principal do mecanismo e alterar dinamicamente a Inteligencia Artificial (IA) do jogo, adaptando-a as habilidades do jogador. Para isso, foram implementadas tres IAs diferentes para simular o comportamento estrategico de jogadores: iniciante, intermediario e experiente no jogo Defense of the Ancient (DotA). Foram realizados experimentos comparando dois jogadores controlados por diferentes IAs e em seguida, testes com usuarios foram realizados com o objetivo de avaliar qualitativamente a abordagem. O mecanismo se mostrou capaz de oferecer um adversario consistente e desafiador em maioria dos casos.
Modelos de crescimento de interfaces rugosas

A evolucao temporal da rugosidade de interfaces geradas durante processos de crescimento geralmente apresenta tres comportamentos distintos: quando as primeiras camadas sao depositadas, o crescimento temporal da rugosidade indica ausencia de correlacoes laterais; para tempos curtos, ocorre um crescimento com o tempo de deposicao segundo uma lei de potencia, com denominado expoente de crescimento; e em tempos longos o sistema atinge o estado estacionario. Neste estado, a rugosidade permanece constante em um valor de saturacao que depende do tamanho do sistema tambem como uma lei de potencia, que define o expoente rda rugosidade. Estes dois expoentes indicam qual classe de universalidade um processo pertence. Estudamos, atraves de simulacao computacional em (1+1) e (2+1) dimensoes, processos que contem duas cineticas ou dois tipos de particulas. O nosso principal interesse e o estudo docrossover entre a classe de universalidade de Edwards-Wilkinson (EW) e a classe de Kardar-Parisi-Shang (KPZ). No limite continuo, estas classes sao definidas por uma equacao diferencial estocastica linear, a EW, e nao-linear, a KPZ. Resultados anteriores de simulacao computacional mostram um crossover com uma v ariacao continua dos expoentes. Neste trabalho, obtivemos resultados semelhantes aos da literatura em simulacoes em pequenos tamanhos. Simulacoes para tamanhos suficientemente grandes revelam outra especie de crossover, previamente observada em solucoes numericas da equacao KPZ: o processo comporta-se na classe de universalidade EW em tempos curtos e, apos um lento crossover atinge o comportamento caracteristico da classe KPZ no limite assintotico. Alem do comportamento temporal da rugosidade, comportamentos do coeficiente de assimetria skewness e da curtose dao suporte ao principal resultado deste trabalho
THE ROLE OF ADVANCED PRACTICE NURSING IN COMMUNITY-ACQUIRED MRSA INFECTION: IMPLICATION FOR PRACTICE AND COMMUNITY HEALTH

In the last 10-15 years community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has become increasingly recognized as a significant, worldwide health problem. CA-MRSA causes skin and soft tissue infections as well as more serious, sometimes life-threatening, pneumonias in otherwise healthy people. Outbreaks of CAMRSA infections have occurred in unexpected groups. Some CA-MRSA strains are particularly virulent and have achieved ecological stability, raising concern that those strains of CA-MRSA could become endemic in certain areas of the country and within certain populations. No generally accepted diagnostic, treatment, or prevention guidelines for practitioners currently exist for CA-MRSA as there are for hospital-acquired MRSA infections (HA-MRSA). This paper reviews currently available pathophysiological, epidemiological, and historical information from various journals and texts, as well as current diagnostic and treatment approaches. The treatment guidelines and algorithm presented here are designed to aid practitioners in their clinical decision-making and interventions when addressing potential CA-MRSA infections.
Online Impedance Measurement of Batteries Using the Cross-Correlation Technique

Electrochemical impedance spectroscopy (EIS) is a powerful test technique that is extensively applied to electrochemical cells for determining the frequency response of the cell impedance. The results from EIS may be used for many applications, such as state of charge (SOC) and state of health. This article presents an approach for online EIS based on cross-correlation technique applied to a boost-type dc–dc charge controller for batteries. The theoretical background is explained and some improvements specific to battery applications are suggested. Preparation of noise datasets, postprocessing of results, and model fitting of the measurements are discussed in detail. The validity of the approach is experimentally confirmed with a digitally controlled boost converter that is charging a 12-V, 7-Ah sealed lead-acid battery: First, the perturbation magnitude is determined experimentally and then the battery is tested via the proposed method at 50% SOC. It is shown that the results of the present approach coincide with those obtained by a commercially available, laboratory-type, high-precision instruments. Finally, the tests were also repeated for 25% and 75% SOC values. It is shown that the proposed approach can be reliably used to analyze the impedance of batteries over a wide frequency range during battery charging process.
Mixed meshfree methods in computational electromagnetism: mathematical foundations and problems in wave scattering

A presente tese versa sobre a extensao dos metodos sem malha ditos nodais a problemas de espalhamento eletromagnetico em tres dimensoes. Tais problemas envolvem quantidades vetoriais, sobre as quais geralmente e imposta uma condicao de divergente nulo. A simples adicao de uma restricao como essa ao divergente torna particularmente dificil a analise via funcoes de forma nodais. Para lidar com ela de uma maneira adequada, precisamos adicionar um multiplicador de Lagrange a versao discretizada das formas fracas resultantes do problema. Desta forma, somos levados a uma formulacao mista que envolve duas quantidades: O campo eletrico e o multiplicador de Lagrange (tambem chamado de pseudopressao). Em seguida, investigamos as condicoes sob as quais a formulacao mista e bem-posta; aqui as chamadas condicoes inf-sup desempenham um papel fundamental. Apos uma profunda exploracao dos teoremas que dao estrutura as formulacoes mistas, observa-se que a abordagem nodal proposta e de fato sustentada por uma firme base matematica. Finalmente, a formulacao meshfree desenvolvida e testada na solucao de varios problemas relativos ao espalhamento eletromagnetico
