Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

We show that strictly abnormal geodesics arise in graded nilpotent Lie groups. We construct such a group, for which some Carnot geodesics are strictly abnormal and, in fact, not normal in any subgroup. In the 2-step case we also prove that these geodesics are always smooth. Our main technique is based on the equations for the normal and abnormal curves, that we derive (for any Lie group) explic...

we report a case of a. naeslundii bacteremia in an 11 year-old boy with persistent fever for two weeks prior hospital admission. he was finally diagnosed with malignant t cell lymphoma. isolation of this bacterium from the blood culture of our patient can serve as an important warning indicating that incuriosity about fastidious and not easily grown bacteria isolated from clinical samples may l...

This paper presents some of our experimental work in quantifying the value of building models about other agents using no more than the observation of others' behavior. We view agent modeling as an iterative and gradual process, where every new piece of information about a particular agent is analyzed in such a way that the model of the agent is further re ned. We present our bayesian-modeler a...

We develop an effective representational and inferential framework for fully deadline-coupled, time-situated problem solving. Our effort is to model an agent in a tight and rigid deadline situation, in need of successfully formulating and executing a deadline-feasible plan of action as the world around the agent continues to change. We highlight the severe time-pressure under which the agent mu...

Fuzzy linear regression (FLR) model can be thought of as a fuzzy variation of classical linear regression model. It has been widely studied and applied in diverse fields. When noise exists in data, it is a very meaningful topic to reveal the dependency between the parameter h (i.e. the threshold value used to measure degree of fit) in FLR model and the input noise. In this paper, the FLR model ...

The author analyzes the actions of Belarusian authorities in situation social rebellion triggered by rigged elections 2020. He puts forward a hypothesis that significant role extinguishing protest potential was played agent deception games conducted KGB, as well parallel repressive and regime’s information offensive, which resulted synergy propaganda disinformation-agent activities.

This paper analyzes the case of a principal who wants to give an agent proper incentives to investigate a hypothesis which can be either true or false. The agent can shirk, thus never proving the hypothesis, or he can avail himself of a known technology to produce fake successes. This latter option either makes the provision of incentives for honesty impossible, or does not distort its costs at...
