Multiple Sclerosis（MS） is a major cause of neurological disability in adults and has an annual cost of approximately $28 billion in the United States. MS is a very complex disorder as demyelination can happen in a variety of locations throughout the brain; therefore, this disease is never the same in two patients making it very hard to predict disease progression. A modeling approach which combines clinical, biological and imaging measures to help treat and fight this disorder is needed. In this paper, I will outline MS as a very heterogeneous disorder, review some potential solutions from the literature, demonstrate the need for a biomarker and will discuss how computational modeling combined with biological, clinical and imaging data can help link disparate observations and decipher complex mechanisms whose solutions are not amenable to simple reductionism.

We present here results from our search for X-ray pulsations of the neu- tron star in the low mass X-ray binary EXO 0748-676 at a frequency near the burst- oscillation frequency of 44.7 Hz. Using the observations made with the Proportional Counter Array onboard the Rossi X-ray Timing Explorer, we did not find any pulsations in the frequency band of 44.4Hz to 45.0Hz and obtained a 3σ upper limit of 0.47% on the pulsed fraction for any possible underlying pulsation in this frequency band. We also discuss the importance of EXO 0748-676 as a promising source for the detection of Gravitational Waves.

Nay or jain Nyay 2： Logic of Atheism of jain Dharm

作者： Mahendra Kumar jain Agam jain University of Delaware

Ethos and logos of the jain thought and practice （world view） is based on reality perceived by senses. Atheistic roots of jain Dharm have nourished growth, maintained viability and vitality, and kept it relevant for over the last five millennia. Unlike Judeo-Christian-Islam or Brahminical faith, it does not rely on omniscient supreme or god. Its atheistic and anti-theistic thrust is generally known, yet its followers do not call themselves Nastik （non-believers）. They emphasize action-consequence relations as guide for successful behaviors with ethical conduct. The basis of their arguments follows from the jain logic （Saptbhangi Syad Nay） of evidence based inference with multiple orthogonal affirmed assertions （jain 2011）. It conserves information by acknowledging the remaining doubt in an inference. It does not assume binary complementation to force closure for deduction with incomplete knowledge which leads to self-reference and loss of information. This approach offers a rational and practical alternative to conundrum of western atheism even though its arguments are logical and consistent with available evidence. It also obviates need to extract religious morality from social mores. Objective truth and knowledge of established generalizations is necessary but not sufficient for subjective searches to shape desires and for what the future ought to be.
