A fundamental aspect of any concurrent system is how processes communicate with each other. Ultimately, all communication involves concurrent reads and writes of shared memory cells, or registers. The stronger the guarantees provided by a register, the more useful it is to the user, but the harder it may be to implement in practice. We consider the problem of implementing a k-ary regular (resp....

In this paper we present a n O(k 1 1=d ) time algorithm for solving the k-center problem in R d , under L 1 and L 2 metrics. The algorithm extends to other metrics, and can be used to solve the discrete k-center problem, as well. We also describe a simple (1 + )-approximation algorithm for the k-center problem, with running time O(n log k) + (k= ) O(k 1 1=d ) . Finally, we present a n O(k 1 1=d...

Recent advances in biotechnology have led to discoveries resulting in major improvements in the therapy of refractory malignancies, although most advanced cancers remain incurable. Thus, there is global consensus around the need to streamline the drug approval process for effective agents. Accelerated Approval and Breakthrough Therapy Designation hold the promise of making new treatments availa...

Abstract Aims Current guidelines recommend surveillance colonoscopy at one year following Colorectal Cancer Resection (CCR), yearly CT chest, abdomen and pelvis, CEA, in 3 years. Previous studies showed no significant difference between CTC detection rates of colorectal cancer or polyps >6mm. A review abnormalities detected on colonoscopies CCR. If the incidence is low Colonography (CTC)...

Students’ self-determination (SD), parental involvement (PI), special education teachers’ support (SETS) in non-academic skills, and college career readiness (CCR) among secondary students with learning disabilities (SLDs) have been assessed from various perspectives. This study focuses on understanding the levels relationship between students’ SD, PI, SETS CCR SLDs schools point of view SLDs, ...

OBJECTIVES To compare the long-term effects of comprehensive outpatient versus inpatient rehabilitation with respect to morbidity and mortality, as well as to changes in physical performance and physical activity. DESIGN A total of 163 consecutive patients were enrolled for comprehensive cardiac rehabilitation (CCR) following a recent coronary event, to outpatient or inpatient CCR according t...

Carbon Catabolite Repression (CCR) has fascinated scientists and researchers around the globe for the past few decades. This important mechanism allows preferential utilization of an energy-efficient and readily available carbon source over relatively less easily accessible carbon sources. This mechanism helps microorganisms to obtain maximum amount of glucose in order to keep pace with their m...

Expression patterns of the cold-circadian rhythm-RNA binding (CCR) and chlorophyll a/b binding (CAB) protein genes have circadian rhythms with phases that are different from each other and are affected differently by cold (4 degrees C) treatment. Cycling of CCR and CAB RNA levels was observed in Arabidopsis seedlings grown for 5 days at 4 degrees C under a light/ dark photoperiod, although the ...

The luteinizing hormone (LH) receptor plays an essential role in male and female gonadal function. Together with the follicle-stimulating hormone (FSH) and thyroid stimulating hormone (TSH) receptors, the LH receptor forms the family of glycoprotein hormone receptors. All glycoprotein hormone receptors share a common modular topography, with an N-terminal extracellular ligand binding domain and...
