Foundations of plasma standards

The field of low-temperature plasmas (LTPs) excels by virtue of its broad intellectual diversity, interdisciplinarity and range of applications. This great diversity also challenges researchers in communicating the outcomes of their investigations, as common practices and expectations for reporting vary widely in the many disciplines that either fall under the LTP umbrella or interact closely with LTP topics. These challenges encompass comparing measurements made in different laboratories, exchanging and sharing computer models, enabling reproducibility in experiments and computations using traceable and transparent methods and data, establishing metrics for reliability, and in translating fundamental findings to practice. In this paper, we address these challenges from the perspective of LTP standards for measurements, diagnostics, computations, reporting and plasma sources. This discussion on standards, or recommended best practices, and in some cases suggestions for standards or best practices, has the goal of improving communication, reproducibility and transparency within the LTP field and fields allied with LTPs. This discussion also acknowledges that standards and best practices, either recommended or at some point enforced, are ultimately a matter of judgment. These standards and recommended practices should not limit innovation nor prevent research breakthroughs from having real-time impact. Ultimately, the goal of our research community is to advance the entire LTP field and the many applications it touches through a shared set of expectations

Serious Games Application for Memory Training Using Egocentric Images

Mild cognitive impairment is the early stage of several neurodegenerative diseases, such as Alzheimer's. In this work, we address the use of lifelogging as a tool to obtain pictures from a patient's daily life from an egocentric point of view. We propose to use them in combination with serious games as a way to provide a non-pharmacological treatment to improve their quality of life. To do so, we introduce a novel computer vision technique that classifies rich and non rich egocentric images and uses them in serious games. We present results over a dataset composed by 10,997 images, recorded by 7 different users, achieving 79% of F1-score. Our model presents the first method used for automatic egocentric images selection applicable to serious games.Comment: 11 page

Zootherapeutics utilized by residents of the community Poço Dantas, Crato-CE, Brazil

<p>Abstract</p> <p>Background</p> <p>Animals have been used as a source of medicine in Brazil since ancient times, and have played a significant role in healing practices. Specifically in Northeast Brazil, zootherapy is a very common practice, and together with medicinal plants, it plays an important role as a therapeutic alternative. In the state of Ceara, no works have been carried out on rural communities with regard to use of zootherapeutics, even though the practice of zootherapy is common in this region. Therefore, the aim of this study was to analyze the use of medicinal animals in a rural community (Poco Dantas) in the municipality of Crato, Ceara, Brazil.</p> <p>Methods</p> <p>The field survey was carried out from October 2008 to January 2009 by conducting interviews using structured questionnaires with 72 people (33 men and 39 women), who provided information on animal species used as remedies, body parts used to prepare the remedies, and ailments for which the remedies were prescribed. We calculated the informant consensus factor (ICF) to determine the consensus over which species are effective for particular ailments, as well as the species use value (UV) to determine the extent of utilization of each species.</p> <p>Results</p> <p>A total of 29 species, distributed in 17 families were categorized as having some medicinal property. The taxa most represented were: mammals (9), insects (7), reptiles and birds (4). <it>Progne chalybea</it>, a species not previously recorded as being of medicinal use, was cited in the present work, where it is utilized in the treatment of alcoholism. The animals are used in the treatment of 34 diseases or symptoms, where sore throat, inflammations and cough are the ailments with the greatest number of citations.</p> <p>Conclusion</p> <p>The data show that zootherapy represents an important therapeutic alternative for the inhabitants of the community. New studies on medicinal fauna should be conducted with the aim of determining the exploitation level of the species utilized, promoting sustainable development of medicinal species that are eventually threatened, and preserving and disseminating the knowledge developed by traditional individuals of the community.</p

Assessment of T-Wave Alternans After Acute Myocardial Infarction: Influence of the Timing of PTCA on Cardiac Electrical Stabilization

Encontra-se bem estabelecido que, na abordagem terapêutica do enfarte agudo do miocárdio (EAM), a trombólise e a angioplastia coronária percutânea (ACTP) permitem diminuir a mortalidade e melhorar o prognóstico, sendo esse benefício tanto maior quanto menor o tempo decorrido entre o evento isquémico e o procedimento terapêutico. No entanto, não está ainda estabelecido qual o impacto que o atraso da implementação dessas terapêuticas tem no desenvolvimento de taquidisritmias ventriculares e por consequência no resultado da alternância da onda T(TWA), que representa um método reconhecido para avaliação da vulnerabilidade ventricular às referidas arritmias. Objectivo: Analisar os resultados da TWA por microvoltagem numa população submetida a ACTP na sequência de EAM e avaliar a influência do timing de revascularização miocárdica nos resultados da TWA. Métodos: Estudámos 79 doentes (67 do sexo masculino; 57 ± 11 anos) consecutivos, admitidos por EAM e sujeitos a revascularização miocárdica por ACTP durante o internamento. A TWA foi avaliada utilizando um aparelho da HeartTwave System (Cambridge Heart, Inc., Bedford, Massachusetts) nos 30 dias pós-EAM. Durante a realização de uma prova de esforço em tapete rolante com protocolo manual, com o objectivo de elevar a frequência cardíaca até aos 110 batimentos por minuto, realizou-se o registo electrocardiográfico através da aplicação de sete eléctrodos standard e outros sete eléctrodos sensores de alta-resolução, especialmente concebidos para redução do «ruído», dispostos segundo as derivações ortogonais de Frank(X,Y, Z). A TWA foi considerada positiva quando se verificou a presença de alternância da onda T de magnitude ³ 1,9 μV de forma consistente e mantida (> 1 minuto), com início para frequências cardíacas < 110 batimentos/minuto ou quando esta alternância se verificou em doentes em repouso. Foi considerada negativa quando se conseguiu obter dados sem artefactos durante pelo menos um minuto, com frequências > 105 batimentos/minuto, sem atingir critério de positividade e indeterminada se não podia ser classificada como positiva ou negativa. Foram excluídos doentes com EAM ou revascularização miocárdica (cirúrgica ou percutânea) prévios, os que apresentavam insuficiência cardíaca congestiva, com fibrilhação auricular, > 10 extrassístoles por minuto, pacemaker definitivo, bradicárdia 130 ms ou sob terapêutica anti-arrítmica. Considerámos como marcador de risco para a ocorrência de eventos arrítmicos ventriculares malignos a presença de TWA positiva ou indeterminada. (TWA «nãonegativa»). Os resultados da TWA foram comparados entre o grupo de doentes submetidos a ACTP nas primeiras 24 horas pós-EAM (Grupo A; n = 45) e o grupo de doentes submetidos a ACTP > 24 horas pós-EAM. (Grupo B; n = 34) Resultados: A TWA foi positiva em 16 doentes (20,2%) e negativa em 56 (70,9%). Em 7 casos (8,9%), o resultado do teste foi considerado indeterminado. A TWA foi «não-negativa» em 29,1% da população. No grupo A a TWA foi “não-negativa” em 9 doentes (20 %) (6 com TWA positiva e três com TWA indeterminada) e negativa em 36 doentes (80 %) e no grupo B foi «não-negativa» em 14 doentes (41%) (10 com TWA positiva e quatro com TWA indeterminada) e negativa em 20 (59 %) (p < 0,05). Não se encontraram diferenças entre os dois grupos no que respeita à fracção de ejecção ventricular esquerda. No seguimento até aos 60 dias após a alta hospitalar não foram documentados eventos arrítmicos ventriculares, síncopes ou óbito. Foram reinternados cinco doentes (7 %) por recorrênciade angor. Conclusões: Numa população de sobreviventes de EAM encontrámos uma prevalência de TWA não negativa de 29 %, apesar da revascularização miocárdica com ACTP. A ACTP, quando efectuada nas primeiras 24 horas após o início do EAM, reduz de forma significativa o número de doentes com TWA não negativa,sugerindo que esta intervenção precoce poderá baixar o risco arrítmico destes doentes e influenciar favoravelmente o prognóstico pós-EAM. O impacto da morte súbita na mortalidade pós-EAM justifica estudos prospectivos de maiores dimensõe

False Positive Responses to Head-Up Tilt Testing in Elderly Patients with Paroxysmal Atrial Fibrillation

The autonomic nervous system (ANS) plays a role as a modulator in the pathogenesis of paroxysmal atrial fibrillation (PAF). The clinical pattern of vagally mediated PAF has been observed mainly in young patients. Neurocardiogenic responses during orthostatic stress are related to autonomic reflexes in which the vagal influence predominates. AIM: To evaluate the susceptibility of elderly patients with PAF to activation of vasovagal syncope mechanisms. METHODS: We performed passive head-up tilt testing (HUT) in 34 patients (62% women, aged 72 +/- 7 years), with > or = 1 year of clinical history of PAF--19 without structural heart disease, 11 with hypertensive heart disease and 4 with coronary artery disease (who had no previous myocardial infarction, had undergone myocardial revascularization, and had no documented ischemia) (PAF group), and compared the results with those obtained in a group of 34 age-matched patients (53% women, aged 74 +/- 6 years), who underwent HUT due to recurrent syncope (Sc group). In this group, 21 had no documented heart disease and none had a clinical history of AF. There was no diabetes, congestive heart failure or syncope in the PAF group. After a supine resting period, the subjects were tilted at 70 degrees for 20 minutes while in sinus rhythm. No provocative agents were used to complement the HUT. ECG and blood pressure were continuously monitored (Task Force Monitor, CNSystems). The test was considered positive when syncope or presyncope occurred with bradycardia and/or arterial hypotension. Abnormal responses were classified as cardioinhibitory, vasodepressor or mixed. RESULTS: HUT was positive in seven patients of the PAF group--vasodepressor response in five and mixed in two (20.5% of the total; 26.3% of those without heart disease)--and in eight patients (vasodepressor in six and mixed in two) of the Sc group (p=NS). During HUT, three patients of the PAF group had short periods of self-limited PAF (in one, after vasodepressor syncope). There were no differences in gender distribution, age or heart disease. No cardioinhibitory responses or orthostatic hypotension were observed. CONCLUSION: In elderly patients with PAF, a significant number of false positive results during passive HUT may be expected, suggesting increased vasovagal reactions despite aging. This suggests that ANS imbalances may be observed in this population

Measuring Invisible Particle Masses Using a Single Short Decay Chain

We consider the mass measurement at hadron colliders for a decay chain of two steps, which ends with a missing particle. Such a topology appears as a subprocess of signal events of many new physics models which contain a dark matter candidate. From the two visible particles coming from the decay chain, only one invariant mass combination can be formed and hence it is na\"ively expected that the masses of the three invisible particles in the decay chain cannot be determined from a single end point of the invariant mass distribution. We show that the event distribution in the $\log(E_{1T}/E_{2T})$ vs. invariant mass-squared plane, where $E_{1T}$, $E_{2T}$ are the transverse energies of the two visible particles, contains the information of all three invisible particle masses and allows them to be extracted individually. The experimental smearing and combinatorial issues pose challenges to the mass measurements. However, in many cases the three invisible particle masses in the decay chain can be determined with reasonable accuracies.Comment: 45 pages, 32 figure

O Efeito da Monitorização Remota em Eventos Cardíacos Adversos numa Amostra Emparelhada por Propensity-Score Matching

AIMS: There are conflicting data regarding the clinical benefits of device-based remote monitoring (RM). We sought to assess the effect of device-based RM on long-term clinical outcomes in recipients of implantable cardioverter-defibrillators (ICDs). METHODS: We assessed the incidence of adverse cardiac events, overall mortality and device therapy efficacy and safety in a propensity score-matched cohort of patients under RM compared to patients under conventional follow-up. Data on hospitalizations, mortality and cause of death were systematically assessed using a nationwide healthcare platform. The primary outcome was time to a composite outcome of first hospital admission for heart failure or cardiovascular death. RESULTS: Of a total of 923 implantable device recipients, 164 matched patients were identified (84 under RM, 84 under conventional follow-up). The mean follow-up was 44 months (range 1-123). There were no significant differences regarding baseline characteristics in the matched cohorts. Patients under RM had a significantly lower incidence of the primary outcome (hazard ratio [HR] 0.42, confidence interval [CI] 0.20-0.88, p=0.022); there was a non-significant trend towards lower overall mortality (HR 0.53, CI 0.27-1.04, p=0.066). No significant differences between cohorts were found regarding appropriate therapies (RM vs. conventional follow-up, 8.1 vs. 8.2%, p=NS) or inappropriate therapies (6.8 vs. 5.0%, p=NS). CONCLUSION: In a propensity score-matched cohort of ICD recipients with long-term follow-up, RM was associated with a lower rate of a combined endpoint of hospital admission for heart failure or cardiovascular death.info:eu-repo/semantics/publishedVersio
