Automotive Ethernet Analyzer

Cílem této práce je navrhnout nástroj pro analýzu rozhraní 100Base-T1 (též známé jako Automotive Ethernet či BroadR-Reach). Práce je rozdělena do čtyř částí. V první části se seznámíme se standardem 100Base-T1 a čím se podobá a odlišuje od nejpoužívanějších standardů Ethernet. Následně na základě těchto znalostí navrhneme koncept jak pasivně monitorovat komunikaci na jednom síťovém segmentu tohoto rozhraní. Ve třetí části je popsána implementace potřebného hardware podle tohoto konceptu. Hardware je navržen tak, aby komunikoval s vývojovou sadou Terasic DE0-Nano-SoC. Poslední část popisuje návrh zdrojového kódu v jazyce VHDL, který dovoluje tomuto hardware fungovat a přeposílat zaznamenané pakety přes rozhraní Gigabit Ethernet, které je zabudované ve vývojové desce.The goal of this thesis is to design an analyzer tool for 100Base-T1 (also known as Automotive Ethernet or BroadR-Reach). It is split into four parts. In the first part, we acquaint ourselves with the 100Base-T1 standard and its intricacies, similarities and dissimilarities to most often used Ethernet standards. Next, based on this knowledge, we design a concept on how to passively monitor communication on a single network segment. In the third part the necessary hardware is implemented in accordance with said concept. The hardware interfaces to an FPGA development board Terasic DE0-Nano-SoC as per the assignment. The last part outlines the implementation of VHDL code that enables the hardware that was implemented to work and forward recorded packets over the development board's built-in Gigabit Ethernet interface

Effect of Convalescent Plasma Therapy on Mortality and Viral Load in Severely Ill Patients with COVID-19

The use of convalescent plasma (CP) appeared to be a promising, easily available and safe way of treatment of severe COVID-19 at the onset of the pandemic in early 2020. Conducted in 2020 and 2021, our study of 52 severely to critically ill COVID-19 patients who received CP plasma as a treatment and of 97 controls found no difference in 30-day or 90-day mortality rates. A significant viral load drop in most patients (4.7 log10 [p<0.001] copies/ml) was observed following CP administration. Retrospective analysis of selected inflammatory markers and immunoglobulins showed higher C-reactive protein levels among the study group, and their decrease on Day 7

The effects of prenatal stress on temperament and problem behavior of 27-month-old toddlers.

Contains fulltext : 48372.pdf (publisher's version ) (Closed access)AIM: To examine, in a prospective study, the influence of prenatal stress on infant temperament and problem behavior. METHOD: Self-report data on stress and anxiety, and levels of cortisol in saliva were collected from nulli-parous women during pregnancy. Temperament of the child was measured at 27 months by parent report on the Infant Characteristics Questionnaire. Behavior of the child was assessed by direct observation during the administration of the Bayley Scales of Development 2-30, and by parent report on the Child Behavior Checklist 2-3. RESULTS: Complete data were available for 103 healthy toddlers. Logistic regression analyses were performed and results were adjusted for possible prenatal, perinatal and postnatal confounders. Perceived stress during pregnancy was a predictor of lower levels of restless/disruptive temperament (OR=0.77), more total behavioral problems (OR=1.17), and more externalizing behavioral problems (OR=1.12) in 2-year-olds. Fear of bearing a handicapped child was a predictor of higher levels of restless/disruptive temperament (OR=1.39) and more attention regulation problems in toddlers (OR=1.46). CONCLUSIONS: Increased levels of maternal prenatal stress appear to be associated with temperamental and behavioral problems in toddlers
