We present the ?3-coordination of 2-phosphaethynthiolate anion in complex (PN)2La(SCP) (2) [PN=N-(2-(diisopropylphosphanyl)-4-methylphenyl)-2,4,6-trimethylanilide)]. Structural comparison with dinuclear thiocyanate-bridged (PN)2La(?-1,3-SCN)2La(PN)2 (3) and azide-bridged (PN)2La(?-1,3-N3)2La(PN)2 (4) complexes indicates that [SCP]? coordination mode is mainly governed by electronic, rather than...

Our aim was to investigate the effects of modifying the carbohydrate-to-lipid ratio of parenteral nutrition (PN) on body composition and the anabolic actions of insulin-like growth factor I (IGF-I) and growth hormone (GH). Adolescent male Sprague-Dawley rats were randomized to receive 7 days of GH, IGF-I (3.5 mg. kg(-1). day(-1) for both) or placebo while receiving high-carbohydrate PN (CHO-PN)...

We prove that lim inf n→∞ pn+1 − pn √ log pn(log log pn) < ∞, where pn denotes the n prime. Since on average pn+1 −pn is asymptotically log pn, this shows that we can always find pairs of primes much closer together than the average. We actually prove a more general result concerning the set of values taken on by the differences p− p between primes which includes the small gap result above.

Emission factors for black carbon (BC) and particle number (PN) were measured from 226 individual heavy-duty (HD) diesel trucks driving through a 1-km-long California highway tunnel in August 2006. Emission factors were based on concurrent increases in BC, PN, and CO2 concentrations (measured at 1 Hz) that corresponded to the passage of individual HD trucks. The distributions of BC and PN emiss...

This study aimed to profile the metabolites, piperine content, and biological activities (antioxidant, anti-inflammatory, anticancer, antibacterial, apoptotic cell) of 15 samples Piper nigrum L. from various geographic regions Thailand. UHPLC-QTOF-MS was applied establish alkaloid profiles P. samples. PCA HCA analysis showed that PN-1, PN-2, PN-11 sources differed significantly those other in t...

In this paper, we consider the liveness enforcement problem in a class of Petri nets (PN) modeling distributed systems. They are called synchronized sequential processes (SSP). The presented design algorithm is based on construction control PN, an abstraction relations T-semiflows, and buffers original nonstructurally live PN. control PN evolves parallel with system, avoiding firi...

Stretching experiments with long double-stranded DNA molecules in physiological ambient revealed a force-induced transition at a force of 65 pN. During this transition between B-DNA and highly overstretched S-DNA the DNA lengthens by a factor of 1.7 of its B-form contour length. Here, we report the occurrence of this so-called B-S transition in short duplexes consisting of 30 basepairs. We empl...

Social behavior diversity is correlated with distinctively distributed patterns of a conserved brain network, which depend on the action of neuroendocrine messengers that integrate extrinsic and intrinsic cues. Arginine vasotocin (AVT) is a key integrator underlying differences in behavior across vertebrate taxa. Weakly electric fish use their electric organ discharges (EODs) as social behavior...

Star configurations are certain unions of linear subspaces of projective space. They have appeared in several different contexts: the study of extremal Hilbert functions for fat point schemes in the plane; the study of secant varieties of some classical algebraic varieties; the study of the resurgence of projective schemes. In this paper we study some algebraic properties of the ideals defining...
