Thermally sensitive neurons present bursting activity for certain temperature ranges, characterized by fast repetitive spiking of action potential followed a short quiescent period. Synchronization is possible in networks coupled neurons, and it sometimes an undesirable feature. Control procedures can suppress totally or partially this collective behavior, with applications deep-brain stimulation techniques. We investigate the control synchronization small-world Hodgkin-Huxley-type thermally...
Considering the estimate that thyroid cancer will become fourth most prevalent type of tumor, improving its diagnosis is a necessity. The gold standard for evaluating nodules ultrasound followed by biopsy. These tests, however, have limitations, especially in smaller than 0.5 cm. Dynamic infrared thermography an imaging method does not require ionizing radiation or contrast injection. aim study was to analyze thermal behavior through using cold stress protocol.The Wilcoxon test showed...
Infrared thermography is a predictive maintenance tool used in substations to identify disturbance electrical equipment that could lead poor operation and potential failure the future. According Joule’s law, temperature of proportional current flowing through it. Other external factors, such as solar incidence, air humidity, wind speed, temperature, can interfere with its operating temperatures. Based on this premise, article aims analyze influence atmospheric load conditions operational...
We investigate the phase-space structure displayed by a system of four waves interacting means nonlinear coupling between two wave triplets, which results in dissipative high-dimensional vector field presenting an invariant manifold, wherein dynamics is essentially conservative. The focus on coexistence large number periodic attractors phase space, with interwoven basins attraction, where low-period have predominance. time behavior nearly conserved quantities and properties Lyapunov spectra...
Neste artigo, apresenta-se análise do desempenho acadêmico dos ingressantes cotistas e não entre os anos 2013-2015 na Universidade Tecnológica Federal Paraná (UTFPR) – Curitiba, matriculados regularmente em 15 cursos. A razão da escolha desse período é devida ao processo seletivo de 2013 atender à Lei no 12. 711/2012, sobre adoção sistema cotas todas as Universidades públicas país. Por meio teste estatístico comparação médias, verificou-se que nove cursos analisados houve diferença...
In this work, we verified how Recurrence quantification analysis (RQA) can help and improve the of profiles patterns in cell lines spectra obtained by Fourier transform infrared (FT-IR) vibration spectroscopy. The results show that recursive pattern differs among MCF7, MDA-MD-231 BT-474 lines. Quantitative recurrence presented consistent with biology breast cancer. molecular subtype greater aggressiveness (MDA-MB-231) laminarity rate less determinism while sample Luminal B (BT-474), lowest...
Este projeto de pesquisa tem por objetivo mapear os banheiros públicos do bairro Centro município Curitiba-PR, analisando a situação acessibilidade dos usuários no que se refere à distância máxima percorrida pelos mesmos até o banheiro público mais próximo. A análise fez partir dados obtidos órgãos e empresas prestadoras serviço prefeitura modelo matemático Problema Máxima Cobertura foi implementado para obtenção resultados nos permite realizar uma avaliação da atual localização em relação...
Abstract Brain trauma patients who underwent decompressive craniectomy make several computed tomography (CT) scans until cranioplasty. Despite recommendations to avoid unnecessary radiological exposure, few studies systematically analyzed the technical parameters employed. CT exams of 14 were retrospectively find display field view (DFOV), dose length product (DLP), volume index (CTDIvol) and effective (ED). The values obtained were: 120 kVp [95% confidence interval (CI) 0.5], 297 mA (95% CI...
Thermography can contribute to the early diagnosis of tumors by identifying nodules that need be analyzed. The objective this paper was verify possible semivariogram curves identify spatial behavior centered in region with nodule and capture thermal behavioral information surroundings point. For this, we used resources R-Studio theoretical basis models. As results verified technique indicates Gaussian both healthy tumor areas, but averages differ from each other. Based on cases analyzed, all...
