The bending triad of the quasi-spherical top molecule SO2F2 in the 550 cm(-1) region
2006
International audience; The analysis of the v(3)/v(7)/v(9) bending triad of SO2F2 has been recently performed with the Watson's Hamiltonian up to octic terms employing 79 rovibrational parameters but including only the first order Coriolis interaction terms, fixed to ab initio values [H. Burger, J. Demaison, F. Hegelund, L. Margules, I. Merke, J. Mol. Struct. 612 (2002) 133-141]. Since SO2F2 is a quasi-spherical top, it can also be considered as derived from the SO42- sulfate ion. We have thus developed a new tensorial formalism in the O(3) > Td > C2v group chain [M. Rotger, V. Boudon, M. Loete, J. Mol. Spectrosc. 216 (2002) 297-307]. This approach allows a systematic development of rovibra…
Both contextual regularity and selective attention affect the reduction of precision‐weighted prediction errors but in distinct manners
2021
Predictive coding model of perception postulates that the primary objective of the brain is to infer the causes of sensory inputs by reducing prediction errors (i.e., the discrepancy between expected and actual information). Moreover, prediction errors are weighted by their precision (i.e., inverse variance), which quantifies the degree of certainty about the variables. There is accumulating evidence that the reduction of precision‐weighted prediction errors can be affected by contextual regularity (as an external factor) and selective attention (as an internal factor). However, it is unclear whether the two factors function together or separately. Here we used electroencephalography (EEG) …
La autopsia en casos de mala praxis
2002
Después de una escueta referencia a la trascendencia de la práctica de las autopsias clínicas, se aborda el problema de la autopsia forense en los casos de mala praxis. Estos pueden ser de muy distinta naturaleza y de la misma forma, los indicios que dejen en el cadáver van a ser también muy variados. Un problema, que puede ser determinante para la investigación, es el momento en el que se practica la autopsia, que puede ser anterior o posterior a la interposición de la reclamación. Asimismo, el estado del cadáver va a condicionar los resultados, atendiendo fundamentalmente a la fase de putrefacción en que se encuentre. Al poner en relación los tipos de mala praxis con las variedades de mue…
Juvenile sudden cardiac death due to congenital coronary ostial valve-like ridges: A case report and literature review
2023
Coronary artery anomalies are a heterogeneous group of congenital disorders affecting the coronary pattern with a characteristic (origin, number, number of hosts, course, etc.). They are rarely found in the population. We report the case of a 21-year-old male who died from sudden cardiac death caused by an isolated coronary ostial obstruction, secondary to a rare anomaly, the presence of a valve-like ridge consisting of a small fold in the Valsalva aortic sinus. The study provides a brief literature review on the pathophysiology, diagnosis, and clinical and medico-legal issues in coronary artery anomaly cases that may be helpful in forensic practice when dealing with sudden cardiac death i…
New Topsentin analogs as inhibitors of biofilm formation
Sparassidae from Japan. II. First Pseudopoda species and new Sinopoda species (Araneae: Sparassidae: Heteropodinae)
2002
The genus Pseudopoda is recorded for the first time from Japan. Pseudopoda kasariana sp. nov. (_??_, _??_) and Pseudopoda spirembolus sp. nov. (_??_, _??_) are described from Amami-oshima Island and Okinawajima Island respectively. Four new Sinopoda species are described: Sinopoda albofasciata (_??_), Sinopoda derivata (_??_, _??_), Sinopoda ogatai (_??_, _??_) and Sinopoda stellatops (_??_, _??_). Sinopoda koreana (Paik 1968) is recorded for the first time from Japan. New records of Sinopoda okinawana Jager & Ono 2000 and S. tanikawai Jager & Ono 2000 are presented. Within the genus Sinopoda Jager 1999 the okinawana species-group is newly diagnosed, which is represented by S. albofasciata …
