RESEARCH DESIGN AND METHODS — Glycemic control, hypoglycemia, and body weight were monitored over 6 years in 826 patients with newly diagnosed type 2 diabetes in 8 of 23 U.K. Prospective Diabetes Study (UKPDS) centers that used a modified protocol. Patients were randomly allocated to a conventional glucose control policy, primarily with diet (n 242) or an intensive policy with insulin alone (n ...

We examine repairable systems with a continous state space and partial repair options, carried out at fixed times n = 1, 2, .... Every time interval [n, n + 1) there is a manufacturing cost and a repair cost. These cost functions are not restricted to the class of bounded functions in this study. Conditions are found under which a control-limit replacement policy minimizes the discounted cost. ...

Background Retaining doctors in rural areas is a challenge in Bangladesh. In this study, we analyzed three rural retention policies: career development programs, compulsory services, and schools outside major cities – in terms of context, contents, actors, and processes.   Methods Series of group discussions between policy-makers and researchers prompted the selection of policy areas, which wer...

In industrial systems, the K-out-of-N: G system is a prominent type of redundancy. The load sharing protects such from malfunctioning/destroying and avoids overload problem that affects reliability in significant manner. this paper we develop Markovian model load-sharing having non-identical repairable components wherein server may on working vacation. During his vacation period, repairs failed...

background in many parts of the world, ongoing deficiencies in health systems compromise the delivery of health interventions. the world health organization (who) identified four functions that health systems need to perform to achieve their goals: efforts to strengthen health systems focus on the way these functions are carried out. while a number of studies on health systems functions have be...

A ciphertext-policy attribute-based encryption scheme allows that an encrypter assigns a decryption policy to ciphertexts. Any user will be able to decrypt if and only if a set of attributes (his private key) satisfy the assigned decryption policy. In this paper we first propose a new chosen ciphertext secure ciphertext-policy attribute-based encryption scheme with constant-size ciphertext and ...
