-coated thin film mirrors are used in high brilliance synchrotron and x-ray free electron laser beamlines due to their low absorption coefficient and high thermal stability. As in the case of gold, platinum, and other thin film mirrors, -coated mirrors also are affected due to synchrotron radiation-induced carbon contaminations in beamlines. In the present study, a graphitic carbon () layer deposited on top of boron carbide ( ) thin film surface is removed by five successive oxygen radio frequency (RF) plasma exposures (RF power, 10 W; flow, 30 sccm; exposure time, 10 min each).

Deposition of synchrotron-radiation-induced carbon contamination on beamline optics causes their performance to deteriorate, especially near the carbon K edge. The photon flux losses due to carbon contamination have spurred researchers to search for a suitable decontamination technique to restore the optical surface and retain its performance. Several in situ and ex situ refurbishing strategies for beamline optics are still under development to solve this serious issue.

Many commentators have acknowledged the fact that the usual courtroom maxim to "tell the truth, the whole truth, and nothing but the truth" is not so easy to apply in practicality. In any given situation, what does the whole truth include? In case, the whole truth includes all the possible alternatives for a given situation, what should a forensic expert witness do when an important question is not asked by the prosecutor? Does the obligation to tell the whole truth mean that all possible, all probable, all reasonably probable, all highly probable, or only the most probable alternatives must be given in response to a question? In this paper, an attempt has been made to review the various ethical issues in different fields of forensic science, forensic psychology, and forensic DNA databases. Some of the ethical issues are common to all fields whereas some are field specific.

Analytical tuning rules for digital PID type-I controllers are presented regardless of the process complexity. This explicit solution allows control engineers 1) to make an accurate examination of the effect of the controller's sampling time to the control loop's performance both in the time and frequency domain 2) to decide when the control has to be I, PI and when the derivative, D, term has to be added or omitted 3) apply this control action to a series of stable benchmark processes regardless of their complexity. The former advantages are considered critical in industry applications, since 1) most of the times the choice of the digital controller's sampling time is based on heuristics and past criteria, 2) there is little a-priori knowledge of the controlled process making the choice of the type of the controller a trial and error exercise 3) model parameters change often depending on the control loop's operating point making in this way, the problem of retuning the controller's parameter a much challenging issue.

Multi-parameter patient monitors (MPMs) have become increasingly important in providing quality healthcare to patients. It is well known in the medical community that there exists an intrinsic relationship between different vital parameters in a healthy person, these include heart rate, blood pressure, respiration rate and oxygen saturation. For example, an increase in blood pressure would lead to a decrease in the heart rate, and vice versa.

Ulcerative colitis (UC) is a refractory, chronic, and nonspecific disease occurred usually in the rectum and the entire colon. The etiopathology is probably related to dysregulation of the mucosal immune response toward the resident bacterial flora together with genetic and environmental factors. Several types of medications are used to control the inflammation or reduce symptoms.

NK cells are a major component of the innate immune system and play an important role in the tissue inflammation associated with autoimmune diseases such as inflammatory bowel disease (IBD). NK cells are unique in bearing both stimulatory and inhibitory receptors specific for MHC class I molecules, and their function is regulated by a series of inhibiting or activating signals. The delicate balance between activation and inhibition that decides NK cell final action provides an opportunity for their possible modulatory effect on specific therapeutic settings.

Article Synopsis
  • The study examined how IL-23p19 is expressed in inflamed mucosa of inflammatory bowel disease (IBD) and its effects on activating immune cells like IEL and NK cells, along with Th17 cell differentiation.
  • IL-23p19 expression was significantly higher in Crohn's disease (CD) compared to ulcerative colitis (UC) and healthy controls, primarily found in macrophages and dendritic cells.
  • The research suggests that high levels of IL-23 in IBD lead to increased activation of immune cells and secretion of proinflammatory cytokines, indicating that therapies targeting IL-23p19 could be beneficial for treating IBD.
