BACKGROUND Since the establishment of free HIV/AIDS care and treatment services in Tanzania a lot of research has been done to assess how health care providers discharge their duties in these clinics. Little research however has been done regarding satisfaction of HIV patients with free health care services provided. OBJECTIVES To determine satisfaction of HIV patients with health care servic...

"The arguments that have been offered ... leave me unsatisfied, however, in the sense that I still want to hear a definition of thein both, and to be told what the effect is of the occurrence of each of them ... "

We derived the critical neighborhood demand in the Schelling’s segregation model by studying the conditions for which a chain reaction of migrations of unsatisfied agents occurs. The essence of Schelling dynamics was approximated in two simplified models: (1) a random walk model for the initial stage of the migrations to illustrate the power-law behavior of chain reaction lengths under critical...

Physician work–life balance has gained significant attention in the last few years as rates of burnout among physicians have increased. Burnout is defined a state mental and physical exhaustion caused by one's professional life.[1] It leads to exhaustion, cynicism, adversely affected work productivity, patient outcomes, interpersonal relationships. Although applies all professions, find it espe...

This paper presents a new evolutionary method for solving the satisfiability problem. It is based on a parallel cellular genetic algorithm which performs global search on a random initial population of individuals and local selective generation of new strings according to new defined genetic operators. The algorithm adopts a diffusion model of information among chromosomes by realizing a two-di...

We provide a comprehensive view of various phase transitions in random K-satisfiability problems solved by stochastic-local-search algorithms. In particular, we focus on the finite-size scaling (FSS) exponent, which is mathematically important and practically useful in analyzing finite systems. Using the FSS theory of nonequilibrium absorbing phase transitions, we show that the density of unsat...
