What is the photon detection efficiency (PDE) of a SiPM? Photon detection efficiency (PDE) refers to the probability that a photon arriving on the SiPM surface is detected, an initiates the process of current pulse generation. PDE is a function of the overvoltage ΔV across the terminals of the APD and wavelength λ of the incident photon. Photon detection efficiency is one of the most important characteristics of a SiPM. PDE is the product of three factors :- Geometrical fill factor (FF), Quantum…
In a groundbreaking study, Baron-Cohen, Leslie, and Frith (1985) compared children with Autism aged between 6 and 16 to two other groups which were, children who suffered from down syndrome aged from 7 to 17, and the control group which were children with no cognitive or social disorders aged from 3 to 6. In comparing these three groups Baron-Cohen et al found the cognitive ability of the three different populations differed. After looking at two different standardized test which were the…
This article analyzes a study conducted by physical therapists, Christy, Chapman, and Murphy (2012), at the University of Alabama in Birmingham in the Birmingham Children’s Health System, on the use of intense physical therapy in children who had cerebral palsy. The physical therapists were testing to see if intense physical therapy had an effect on gross motor function, community walking and participation. Physical therapy is commonly used with children who have cerebral palsy. It has been…
A wave is a disturbance of energy. Sound and light are both disturbances in energy, and they both travel in the forms of waves. While sound travels in a longitudinal wave, light travels through a transverse wave. From a perspective of a human, sound and light on earth is very different compared to sound and light in space. These waves have differences in speed, form, shape, and other properties. Despite many of the differences, sound and light are very similar to each other. Light is a…
After reading about the life of Temple Grandin, there are three things of which I am presently aware. The first, is that, the many diverse causes and symptoms of autism are stigmatized in mainstream culture. This includes the severity and frequency of these occurrences. Secondly, regardless of the specific conditions, autism almost always effects the same three characteristics of the brain.These are, feelings towards others, communication, and imagination. Lastly, I have realized that autism…
As one drives down the highway and catch a glance of someone in a bright red vehicle, one can’t help to turn their heads. There something about the color red that grabs the general public attention. “Although red is not technically the most visible color, it has the property of appearing to be nearer than it is and therefore it grabs people’s attention (Psychological)”. In the movie American Beauty, directed by Sam Menden, Menden uses red as a symbolism for power, danger, and determination to…
Introduction In my experience, people who haven’t researched Autism Spectrum Disorder only know of the odd behavior that is caused by it. Chantel Sicile-Kira says, “In the past, nonverbal children with autism were considered mentally retarded, and those who had difficulties in communication were considered intellectually slow.” Some have found it interesting that, autism is a disorder that evolves during the developmental stages of a child’s life (Dupler). The focus of this research is to…
Autism reflects reduced or no development of verbal or communicative social behavior in children. Though the motor and other developments are quite appropriate, lack of coordination in these movements may be visible. Various hypothesis and studies have been carried out in an attempt to understand exact patho-physiology of autism. But almost all studies point to the fact that disruption in the early fetal brain development results in autistic behavior. What signs and symptoms are observed in…
