Call centers attribute different values to different customer segments. These values are reflected in qualityof-service targets. The prevelant Target Service Factor (TSF) formulation requires, for example, that 80% of VIP customers wait less than 20 seconds while setting the target to 30 seconds for non-VIP customers. The call center must determine the staffing level together with a prioritizat...

BACKGROUND Since protein-calorie malnutrition is a common factor influencing morbidity and mortality of haemodialysis patients, assessing their nutritional status is important. The aim of this study was to investigate the predictive value of anthropometric parameters on mortality and their interrelationship. METHODS The study included a cohort of 242 patients. The analysis involved baseline d...

We report the NQR study on the pressure-induced paramagnetic state in the antiferromagnetic (AF) intermetallic compound YMn2 with the Néel temperature TN=100 K at ambient pressure. From the T variation of the nuclear spin-lattice relaxation rate, (1/T1) of Mn above the critical pressure of 4 kbar, the spin fluctuation feature is found to change below a temperature Tsf. At higher temperature tha...

We overview two tracks of the TAC2013 Knowledge Base Population (KBP) evaluation: English slot filling (SF) and temporal slot filling (TSF). The goal of these two KBP tracks is to promote research in the extraction of relations between named entities from free text (SF), and identify the temporal intervals when these relations were valid (TSF). The main changes this year include the requirement...

The distribution shift in Time Series Forecasting (TSF), indicating series changes over time, largely hinders the performance of TSF models. Existing works towards time are mostly limited quantification and, more importantly, overlook potential between lookback and horizon windows. To address above challenges, we systematically summarize into two categories. Regarding windows as input-space out...

Specific amino acid substitutions confer a temperature-sensitive-folding (tsf) phenotype to bacteriophage P22 coat protein. Additional amino acid substitutions, called suppressor substitutions (su), relieve the tsf phenotype. These su substitutions are proposed to increase the efficiency of procapsid assembly, favoring correct folding over improper aggregation. Our recent studies indicate that ...

The tsf genes from Streptomyces coelicolor A3(2) and Streptomyces ramocissimus, encoding the guanine-nucleotide exchange factor EF-Ts, were cloned and sequenced. Streptomycetes have multiple and highly divergent EF-Tu species, with EF-Tu1 and EF-Tu3 showing only about 65% amino acid sequence identity, and yet these can apparently interact with a single EF-Ts species. tsf lies in an operon with ...

PURPOSE Adolescent tibia vara is a multiplanar deformity that can lead to progressive deformity, altered gait, unequal leg lengths, and premature knee arthritis if uncorrected. The purpose of the current study is to report our experience in management of adolescent tibia vara using Taylor Spatial Frame (TSF). MATERIALS AND METHODS A prospective study of eleven adolescent tibia vara patients m...

Although developmental dyslexia (DD) is frequently associate with a phonological deficit, the underlying neurobiological cause remains undetermined. Recently, a new model, called "temporal sampling framework" (TSF), provided an innovative prospect in the DD study. TSF suggests that deficits in syllabic perception at a specific temporal frequencies are the critical basis for the poor reading per...

BACKGROUND Most reports regarding the obesity paradox have focused on body mass index (BMI) to classify obesity and the prognostic values of other indirect measurements of body composition remain poorly examined in heart failure (HF). OBJECTIVE To evaluate the association between BMI and other indirect, but easily accessible, body composition measurements associated with the risk of all-cause...
