Star Product and Invariant Integration for Lie type Noncommutative Spacetimes

We present a star product for noncommutative spaces of Lie type, including the so called ``canonical'' case by introducing a central generator, which is compatible with translations and admits a simple, manageable definition of an invariant integral. A quasi-cyclicity property for the latter is shown to hold, which reduces to exact cyclicity when the adjoint representation of the underlying Lie algebra is traceless. Several explicit examples illuminate the formalism, dealing with kappa-Minkowski spacetime and the Heisenberg algebra (``canonical'' noncommutative 2-plane).Comment: 21 page

The effectiveness of the anti-CD11d treatment is reduced in rat models of spinal cord injury that produce significant levels of intraspinal hemorrhage

We have previously reported that administration of a CD11d monoclonal antibody (mAb) improves recovery in a clip-compression model of SCI. In this model the CD11d mAb reduces the infiltration of activated leukocytes into the injured spinal cord (as indicated by reduced intraspinal MPO). However not all anti-inflammatory strategies have reported beneficial results, suggesting that success of the CD11d mAb treatment may depend on the type or severity of the injury. We therefore tested the CD11d mAb treatment in a rat hemi-contusion model of cervical SCI. In contrast to its effects in the clip-compression model, the CD11d mAb treatment did not improve forelimb function nor did it significantly reduce MPO levels in the hemi-contused cord. To determine if the disparate results using the CD11d mAb were due to the biomechanical nature of the cord injury (compression SCI versus contusion SCI) or to the spinal level of the injury (12th thoracic level versus cervical) we further evaluated the CD11d mAb treatment after a T12 contusion SCI. In contrast to the T12 clip compression SCI, the CD11d mAb treatment did not improve locomotor recovery or significantly reduce MPO levels after T12 contusion SCI. Lesion analyses revealed increased levels of hemorrhage after contusion SCI compared to clip-compression SCI. SCI that is accompanied by increased intraspinal hemorrhage would be predicted to be refractory to the CD11d mAb therapy as this approach targets leukocyte diapedesis through the intact vasculature. These results suggest that the disparate results of the anti-CD11d treatment in contusion and clip-compression models of SCI are due to the different pathophysiological mechanisms that dominate these two types of spinal cord injuries

Effect of Photoperiod on Some Zootechnical Performances of Quail (Coturnix Coturnix Japonica) Raised in Cage in Côte D’Ivoire

A study was conducted in Ismorel farm at Adiake, Côte d'Ivoire, to determine effect of photoperiod on some zootechnical performances of the quail (Coturnix coturnix japonica). One-day-old quail was separated into two photoperiodic groups, including group A (NL: 12-AL: 12) and group B (NL: 12-AL: 0). After one week of age, each group was divided into two subgroups. Group A was divided into subgroups A1 (NL: 12-AL: 12) and A2 (NL: 12-AL: 4) while group B was divided into subgroups B1 (NL: 12-AL: 0) and B2 (NL: 12-AL: 4). The experiment lasted 18 months with 6 months for a repetition, it ran from November 2016 to May 2018. During this experiment, 2960 chicks were used for the experiment and 2775 eggs were collected to determine fertility rate and hatching rate. Results showed a significant effect (p <0.05) of photoperiod on body weight in favor of group A (NL: 12-AL: 12) and subgroup A1 (NL: 12-AL: 12).A significant difference (p <0.05) in photoperiod on egg weight, egg diameter, and egg laying rate was observed in favor of quail in A1 (NL: 12-AL: 12) and B1 (NL: 12-AL: 0). On the other hand, photoperiod had no influence (p> 0.05) on the length of eggs, fertility rate, hatching rate and mortality rate according to different subgroups formed

The validation service of the hydrological SAF geostationary and polar satellite precipitation products

Abstract. The development phase (DP) of the EUMETSAT Satellite Application Facility for Support to Operational Hydrology and Water Management (H-SAF) led to the design and implementation of several precipitation products, after 5 yr (2005–2010) of activity. Presently, five precipitation estimation algorithms based on data from passive microwave and infrared sensors, on board geostationary and sun-synchronous platforms, function in operational mode at the H-SAF hosting institute to provide near real-time precipitation products at different spatial and temporal resolutions. In order to evaluate the precipitation product accuracy, a validation activity has been established since the beginning of the project. A Precipitation Product Validation Group (PPVG) works in parallel with the development of the estimation algorithms with two aims: to provide the algorithm developers with indications to refine algorithms and products, and to evaluate the error structure to be associated with the operational products. In this paper, the framework of the PPVG is presented: (a) the characteristics of the ground reference data available to H-SAF (i.e. radar and rain gauge networks), (b) the agreed upon validation strategy settled among the eight European countries participating in the PPVG, and (c) the steps of the validation procedures. The quality of the reference data is discussed, and the efforts for its improvement are outlined, with special emphasis on the definition of a ground radar quality map and on the implementation of a suitable rain gauge interpolation algorithm. The work done during the H-SAF development phase has led the PPVG to converge into a common validation procedure among the members, taking advantage of the experience acquired by each one of them in the validation of H-SAF products. The methodology is presented here, indicating the main steps of the validation procedure (ground data quality control, spatial interpolation, up-scaling of radar data vs. satellite grid, statistical score evaluation, case study analysis). Finally, an overview of the results is presented, focusing on the monthly statistical indicators, referred to the satellite product performances over different seasons and areas

Artificial Intelligence in Medicine, Current Uses, and Future Perspectives

La inteligencia artificial (IA) es una clase de tecnología que busca desarrollar sistemas que simulen la capacidad del razonamiento humano. En el campo de la medicina actualmente se ha buscado utilizar estos sistemas en múltiples áreas como la radiología, patología, cirugía, entre otras. Algunos usos actuales incluyen la facilitación en la interpretación de estudios diagnósticos y soporte para la toma de algunas decisiones clínicas. El objetivo final de dichos sistemas es que mejoren los desenlaces de los pacientes, al igual que faciliten y optimicen los procesos en diversas áreas de la medicina. En el futuro se espera que sistemas con modelos generalistas de IA logren apoyar en la toma de decisiones médicas complejas, y faciliten procesos que actualmente son tediosos para los profesionales de la salud. A pesar de múltiples ventajas la IA cuenta con limitaciones importantes, por lo que se espera que su papel en la atención médica será más de apoyo que un reemplazo de los profesionales de la salud.Artificial intelligence is a new class that aims to simulate the human thought process. In the medical field, there has been an interest in using these systems in many areas, such as radiology, pathology, and surgery, among others. Some current uses include aiding in interpreting diverse diagnostic studies and supporting some medical decisions. The primary objectives of these systems are to improve patient outcomes and optimize medical processes in different areas. In the future, it is expected that generalist AI models will help physicians with tedious tasks and that they will be a tool for difficult medical decisions. Despite all the advantages of AI, it has its limitations; therefore, AI is not expected to replace physicians, but it will be a powerful aid.&nbsp

The Human Affectome

Over the last decades, the interdisciplinary field of the affective sciences has seen proliferation rather than integration of theoretical perspectives. This is due to differences in metaphysical and mechanistic assumptions about human affective phenomena (what they are and how they work) which, shaped by academic motivations and values, have determined the affective constructs and operationalizations. An assumption on the purpose of affective phenomena can be used as a teleological principle to guide the construction of a common set of metaphysical and mechanistic assumptions—a framework for human affective research. In this capstone paper for the special issue “Towards an Integrated Understanding of the Human Affectome”, we gather the tiered purpose of human affective phenomena to synthesize assumptions that account for human affective phenomena collectively. This teleologically-grounded framework offers a principled agenda and launchpad for both organizing existing perspectives and generating new ones. Ultimately, we hope Human Affectome brings us a step closer to not only an integrated understanding of human affective phenomena, but an integrated field for affective research

The use of chemotherapy regimens carrying a moderate or high risk of febrile neutropenia and the corresponding management of febrile neutropenia: an expert survey in breast cancer and non-Hodgkin's lymphoma

The use of chemotherapy regimens with moderate or high risk of febrile neutropenia (defined as having a FN incidence of 10% or more) and the respective incidence and clinical management of FN in breast cancer and NHL has not been studied in Belgium. The existence of a medical need for G-CSF primary and secondary prophylaxis with these regimens was investigated in a real-life setting.Journal ArticleMulticenter StudyResearch Support, Non-U.S. Gov'tSCOPUS: ar.jinfo:eu-repo/semantics/publishe
