arlier this year, a number of leaders from major U.S. corporations gathered at Sunnylands in California to discuss the critical importance of basic scientific research. For decades, the private sector has withdrawn from some areas of basic research, as accelerating market pressures, the speed of innovation, and the need to protect intellectual property in a global marketplace made a Bell Labs–s...

Based on a composite of several measurement series performed on ice samples stored at −25 C or −50 C, we present and discuss the first δO2/N2 record of trapped air from the EPICA Dome C (EDC) ice core covering the period between 300 and 800 ka (thousands of years before present). The samples stored at −25 C show clear gas loss affecting the precision and mean level of the δO2/N2 record. Two dif...

We present a faster implementation of the polynomial time primal simplex algorithm due to Orlin [23]. His algorithm requires O(nm min{log(nC), m log n}) pivots and O(n m · min{log nC, m log n}) time. The bottleneck operations in his algorithm are performing the relabeling operations on nodes, selecting entering arcs for pivots, and performing the pivots. We show how to speed up these operations...

The main objective of this study was to determine the concurrent validity between a hand-held (HHD) and mounted dynamometer (MHHD) for assessing isometric neck strength. Observational design. Semiprofessional rugby club. Nineteen semi-professional players (age = 26 ± 5 years, stature 186.5 6.5 cm, body mass 98.7 12.8 kg). Concurrent (limits agreement, correlation) HHD MHHD, intrarater reliabili...

779 primary and high school boys of East-Tehran were evaluated in 1984. The occurance of pubic hair and testicular development were investigated and rated according to Marshall and Tanner's clas- sification. The pubic hair begun to develop between 6.5 years and 15.1 years in all boys (mean= 9.28 ±- 1.02). In age group of 10 years 62.5%, 12 years 80%, 14 years 94.3% and 16 years 100% of the boys...

Meaning of a word varies from one domain to another. Despite this important domain dependence in word semantics, existing word representation learning methods are bound to a single domain. Given a pair of source-target domains, we propose an unsupervised method for learning domain-specific word representations that accurately capture the domainspecific aspects of word semantics. First, we selec...

OBJECTIVES Current criteria of the N-category in the TNM staging system for carcinoma of the esophagus needs further subgrouping due to its simplicity in mixing together patients with different prognosis. METHOD A retrospective cohort study of 186 patients (176 men and ten women; mean age, 59.9 years) with squamous cell carcinoma (SCC) of the thoracic esophagus who underwent esophagectomy fol...

Metal ion coordination to nucleic acids is not only required for charge neutralization, it is also essential for the biological function of nucleic acids. The structural impact of different metal ion coordinations of DNA helices is an open question. We carried out X-ray diffraction analyses of the interactions of the two transition metal ions Co(II) and Cu(II) and an alkaline earth metal ion Ba...
