Electrochemical and biological performance of hierarchical platinum-iridium electrodes structured by a femtosecond laser by Linze Li, Changqing Jiang, Wanru Duan, Zhiyan Wang, Feng Zhang, Changgeng He, Tiangang Long, Luming Li

“…In this study, we explored the electrochemical performance, biological response, and tissue adhesion of hierarchical Pt-Ir electrodes by implantation in adult rat brains for 1, 8, and 16 weeks. Regular smooth Pt-Ir electrodes were used as a control. …”

Convergence of a Gradient-Based Learning Algorithm With Penalty for Ridge Polynomial Neural Networks by Qinwei Fan, Jigen Peng, Haiyang Li, Shoujin Lin

“…We also demonstrate the efficiency of our proposed algorithm by numerical experiments, and compare it to the no regularizer, <inline-formula> <tex-math notation="LaTeX">$L_{2}$ </tex-math></inline-formula> regularizer, <inline-formula> <tex-math notation="LaTeX">$L_{1/2}$ </tex-math></inline-formula> regularizer, smoothing <inline-formula> <tex-math notation="LaTeX">$L_{1/2}$ </tex-math></inline-formula> regularizer, and the Group Lasso regularizer, and also the relevant theoretical analysis has been verified.…”

Value of vessel wall magnetic resonance imaging in the diagnosis of cerebrovascular diseases by Sherien Farag, Hany Zaki El-Dien, Yasser Abdelazeem, Mohammed Khaled Elewa, Khaled Abdelmaksoud, Ahmed ElSadek

“…Further high-field MR unit (3 Tesla MRI Scanner) was used to obtain vessel wall MR sequences (T1 pre-post contrast and T2 fat sat) to differentiate between intracranial atherosclerotic plaque, vasculitis, and moyamoya disease and to assess atherosclerotic plaque activity (vulnerability) Results Vessel wall MR imaging showed arterial wall thickening with irregular inner margin and eccentric enhancement in cases of intracranial atherosclerosis, where as in case of CNS vasculitis, it showed circumferential wall enhancement with regular smooth inner margin. In cases of moyamoya disease, the vessel wall MR showed a narrowing of the luminal artery without post-contrast enhancement of the wall, no hemorrhagic nor fatty content. …”

Factors associated with subcentimeter pulmonary nodule outcomes followed with computed tomography imaging in oncology patients by André Queiroz de Morais, Thiago Pereira Fernandes da Silva, Juliana Cristina Duarte Braga, Diogo Fábio Dias Teixeira, Paula Nicole Vieira Pinto Barbosa, Fábio José Haddad, Jefferson Luiz Gross, Pablo Rydz Pinheiro Santana, Bruno Hochhegger, Edson Marchiori, Marcos Duarte Guimarães

“…PNs with irregular, lobuled, or spiculated margins exhibited faster growth than PNs with regular, smooth margins. Malignancy of PNs was found to be significantly associated with being male, a primary colorectal cancer diagnosis, and advanced stage disease. …”

Incidence of rough and irregular atmospheric ice particles from Small Ice Detector 3 measurements by Z. Ulanowski, P. H. Kaye, E. Hirst, R. S. Greenaway, R. J. Cotton, E. Hesse, C. T. Collier

“…Overall, the roughness and complexity are expected to lead to increased shortwave cloud reflectivity, in comparison with cirrus composed of more regular, smooth ice crystal shapes. These findings put into question suggestions that climate could be modified through aerosol seeding to reduce cirrus cover and optical depth, as the seeding may result in decreased shortwave reflectivity.…”

“Bread and butter” fibrinous pericarditis by Pedro Mansueto Melo de Souza, Adriele Machado dos Santos, Eurides Martins Paulino, Carlos Gustavo Hirth, Conceição Aparecida Dornelas

“…In the 19th century, Sir William Osler stated that pericarditis was one of the most serious diseases overlooked by practitioners.3 Even so, the rate of hospitalization by this diagnosis is estimated in 3.32 cases per 100,000 person-years, which corresponds to 0.2% of all causes of hospitalization in cardiology centers,4 with an incidence of 1.06% found in autopsy case series.5 Didactically, pericarditis can be morphologically classified in five types: (i) fibrinous; (ii) serous; (iii) purulent; (iv) hemorrhagic; or (v) caseous.6 The image presented herein refers to a typical fibrinous pericarditis, also known as “bread and butter” pericarditis.7 In such an entity, the pericardium, which is regularly smooth and bright, becomes opaque and granular, and macroscopically resembles two pieces of buttered bread pressed together then pulled apart. …”
