Therapeutic decision making in autoimmune and inflammatory disorders of the central nervous system in children.

ABSTRACT Autoimmune and inflammatory disorders of the central nervous system can result in significant morbidity and mortality. Through the recognition of syndromes using diagnostic biomarkers, the clinician is now able to use immune suppressive therapies to improve outcomes. However, the therapeutic decision-making process is complex. The clinician has to balance the risk of disease, with the risk of treatment side effects. To achieve this balance, it is important to understand the natural history of disease, the risk of residual disability, the risk of relapse, and risk of a fatal outcome. It is also important to have some understanding of the pathological processes, as some of the entities have more reversible processes, whereas others have destructive processes. This review will assess the dynamic nature of this decision-making process, and compare some of the more severe diseases such as neuromyelitis optica, anti-N-methyl-D-aspartate receptor encephalitis and opsoclonus myoclonus ataxia syndrome, with disorders with more favourable outcomes such as Sydenham chorea and post-infectious cerebellar ataxia

Spatio-temporal variation of conversational utterances on Twitter

Conversations reflect the existing norms of a language. Previously, we found that utterance lengths in English fictional conversations in books and movies have shortened over a period of 200 years. In this work, we show that this shortening occurs even for a brief period of 3 years (September 2009-December 2012) using 229 million utterances from Twitter. Furthermore, the subset of geographically-tagged tweets from the United States show an inverse proportion between utterance lengths and the state-level percentage of the Black population. We argue that shortening of utterances can be explained by the increasing usage of jargon including coined words.Comment: 13 pages, 7 figures, published in PLoS On

Estimation of energy and material use of sintering-based construction for a lunar outpost - with the example of SinterHab module design

In this paper, we would revisit the usability of microwave for lunar regolith sintering through an in-depth experiment, and examine the minimum materials and energy required for sintering based on the SinterHab design. This will include the minimum layers to print, estimated printing time, minimum energy required for the sintering process and the potential energy sources

A variety of lepton number violating processes related to Majorana neutrino masses

A Majorana type of the neutrino mass matrix induces a class of lepton number violating processes. Cross sections of these reactions are given in terms of the neutrino mass matrix element, and a semi-realistic event rate is estimated. These processes provide mass and mixing parameters not directly accessible by the neutrino oscillation experiments. If these processes are discovered with a larger rate than given here, it would imply a new physics of the lepton number violation not directly related to the Majorana neutrino mass, such as R-parity violating operators in SUSY models.Comment: 15 pages, 1 figur

Silicon resistor to measure temperature during rapid thermal annealing

A resistor composed of a piece of Si wafer and two thin silver wires attached to it, can reliably sense the temperature during rapid thermal annealing (RTA). As constant electric current passes through the Si piece, the resistivity change of Si with temperature produces a voltage signal that can be readily calibrated and converted to an actual temperature of the samples. An accuracy better than ±10 °C is achieved between 300° and 600 °C

Self-organizing, two-temperature Ising model describing human segregation

A two-temperature Ising-Schelling model is introduced and studied for describing human segregation. The self-organized Ising model with Glauber kinetics simulated by M\"uller et al. exhibits a phase transition between segregated and mixed phases mimicking the change of tolerance (local temperature) of individuals. The effect of external noise is considered here as a second temperature added to the decision of individuals who consider change of accommodation. A numerical evidence is presented for a discontinuous phase transition of the magnetization.Comment: 5 pages, 4 page
