A bootstrapping soft shrinkage approach was utilized for variable selection. The importance of a variable was evaluated by both variable selecting frequency and standardized regression coefficient.

Abstract:

Many physiological and synthetic agents act by occluding the ion conduction pore of ion channels. A hallmark of charged blockers is that their apparent affinity for the pore usually varies with membrane voltage. Two models have been proposed to explain this voltage sensitivity. One model assumes that the charged blocker itself directly senses the transmembrane electric field, i.e., that blocker binding is intrinsically voltage dependent. In the alternative model, the blocker does not directly interact with the electric field; instead, blocker binding acquires voltage dependence solely through

Abstract:

A gain-of-function mutation in the Caenorhabditis elegans exp-2 K+-channel gene is caused by a cysteine-to-tyrosine change (C480Y) in the sixth transmembrane segment of the channel (Davis, M.W., R. Fleischhauer, J.A. Dent, R.H. Joho, and L. Avery. 1999. Science. 286:2501–2504). In contrast to wild-type EXP-2 channels, homotetrameric C480Y mutant channels are open even at −160 mV, explaining the lethality of the homozygous mutant. We modeled the structure of EXP-2 on the 3-D scaffold of the K+ channel KcsA. In the C480Y mutant, tyrosine 480 protrudes from S6 to near S5, suggesting that the bulk

Construction of a FEM full model of the bearing, taking into account the shape of the rolling elements and the determination of the contact problem for every rolling element, leads to a singularity of stiffness matrix, which in turn makes the problem impossible to

Abstract Background: The RICOVER60 trial has shown that 6 cycles of CHOP-14 with 8 applications of rituximab (6xR-CHOP-14) was superior to 8xR-CHOP-14, 6xCHOP-14 and 8xCHOP-14 in elderly patients with CD20-positive aggressive lymphoma. In that trial 117/306 (36%) of the patients in the 6xR-CHOP-14 arm were assigned to receive additional radiotherapy (Rx) to bulky disease (Pfreundschuh et al., Lancet Oncol. 2008). To study the relevance of additional Rx to bulky disease we subsequently initiated a prospective study in which no Rx was planned after 6 × R-CHOP-14. Methods: 166 elderly patients -

The paper presents experimental values of lateral and extension transmission ultrasonic waves speed and their absorbance coefficient obtained with the help of discrete immersed method in metal filled polymer auxetic samples with polyurethane matrix. Poisson’s ratio, real and imaginary parts of complex dynamic elastic modulus (Young’s modulus, shear modulus, bulk modulus) and mechanical losses tangent of angle for extension, lateral and bulk deformation have been calculated regarding paper’s results. Viscoelastic properties of polyurethane auxetic have been examined regarding different theoreti

Abstract:

Hand pose estimation using a multi-camera system allows natural non-contact interfacing unlike when using bulky data gloves. To enable any user to use the system regardless of gender or physical differences such as hand size, we propose hand model individualization using only multiple cameras. From the calibration motion, our method estimates the finger link lengths as well as the hand shape by minimizing the gap between the hand model and observation. We confirmed the feasibility of our proposal by comparing 1) actual and estimated link lengths and 2) hand pose estimation results using our ca

Abstract:

Three-coordinate iron sites are potentially important intermediates in the reduction of dinitrogen by the enzyme nitrogenase, but synthetic work to outline the behavior of three-coordinate iron complexes is in its infancy. Recent work shows that bulky diketiminate ligands give a general route to three-coordinate iron complexes with a variety of third ligands. The low coordination number leads to exciting new reactions in which NN bonds are weakened or broken. Such complexes show great promise for evaluating the ability of low-coordinate iron to perform bond cleavage reactions akin to the indi

Abstract Introduction: few studies have explored the usefulness of a prognostic index specifically devised for patients with localized DLBCL. The IIL has performed a retrospective analysis of a large group of patients with limited stage DLBCL and developed a new prognostic model. Results: 1,252 patients with localized (Ann Arbor stage I-II) aggressive B-cell lymphoma (IWF: G or H, WHO:DLBCL) diagnosed from 1988 to 2002 and without CNS involvement, treated by 4 cooperative groups and 2 single institutions, are the subject of this analysis.

Abstract:

N-Acyloxy-N-alkoxyamides 1a are unusual anomeric amides that are pyramidal at the nitrogen because of bis oxyl substitution. Through this configuration, they lose most of their amide character and resemble α-haloketones in reactivity. They are susceptible to SN2 reactions at nitrogen, a process that is responsible for their mutagenic behaviour. Kinetic studies have been carried out with the nucleophile N-methylaniline that show that, like SN2 reactions at carbon centres, the rate constant for SN2 displacement of carboxylate is lowered by branching β to the nitrogen centre, or bulky groups on t

Abstract:

AbstractVector beams with phase modulation in a high numerical aperture system are able to break through the diffraction limit. However, the implementation of such a device requires a combination of several discrete bulky optical elements, increasing its complexity and possibility of the optical loss. Dielectric metalens, an ultrathin and planar nanostructure, has a potential to replace bulky optical elements, but its optimization with full-wave simulations is time-consuming. In this paper, an accurate and efficient theoretical model of planar metalens is developed. Based on this model, a twof

Abstract Introduction: Chronic lymphocytic leukemia (CLL) has a heterogeneous clinical course, with many patients (pts) experiencing relapse after initial treatment. Ibrutinib is a first-in-class once-daily, oral, inhibitor of Bruton's tyrosine kinase indicated for treatment of pts with CLL with ≥1 prior therapy and for pts with 17p deletion CLL. Extended follow-up of ibrutinib-treated pts has demonstrated an increase in complete response (CR) rate over time (Byrd, Blood 2015; Brown, Blood 2015). This ad hoc analysis examines baseline factors predictive of CR in pts with CLL/SLL treated with i

Assessing the robotization level of technological processes in livestock complexes based on the breeding, authors found that the most free niche of robotization of technological processes in livestock complexes is the feeding process, which forms 55 percent of milk productivity. There is a need to develop a wheeled robotic platform that will ensure the availability of the feed mixture along the feeding front. This platform will multi-stage saturate the bulky components of the feed mixture with concentrated ones, increasing their attractiveness to animals, while normalizing the balance of dry m
