Study on Temperature and Synthetic Compensation of Piezo-Resistive Differential Pressure Sensors by Coupled Simulated Annealing and Simplex Optimized Kernel Extreme Learning Machine.

Sensors (Basel, Switzerland)

Li J, Hu G, Zhou Y, Zou C, Peng W, Alam Sm J.
PMID: 28422080
Sensors (Basel). 2017 Apr 19;17(4). doi: 10.3390/s17040894.

As a high performance-cost ratio solution for differential pressure measurement, piezo-resistive differential pressure sensors are widely used in engineering processes. However, their performance is severely affected by the environmental temperature and the static pressure applied to them. In order...

Ubiquitin Signaling: Chemistry Comes to the Rescue.

Journal of the American Chemical Society

Mali SM, Singh SK, Eid E, Brik A.
PMID: 28328208
J Am Chem Soc. 2017 Apr 12;139(14):4971-4986. doi: 10.1021/jacs.7b00089. Epub 2017 Mar 28.

Posttranslational modification of proteins by ubiquitin (Ub), i.e., ubiquitination, mediates a variety of cellular processes, including protein homeostasis, cell cycle, DNA repair, and viral infections. Understanding the molecular mechanism of ubiquitination in these events is the basis for unraveling...

Ensemble of Pinanones from the Permanganate Oxidation of Myrtenal.

The Journal of organic chemistry

Clay JM, Hesek D, Oliver AG, Lee M, Fisher JF.
PMID: 27281133
J Org Chem. 2016 Jul 01;81(13):5705-9. doi: 10.1021/acs.joc.6b00756. Epub 2016 Jun 23.

The buffered permanganate oxidation of (-)-myternal, a member of the pinene family, provides the α-hydroxyketone (-)-(1R,3S,5R)-3-hydroxy-6,6-dimethylbicyclo[3.1.1]heptan-2-one in preparative yield (65% on a multigram scale). This α-hydroxyketone is oxidized, in a second reaction, to the α,β-diketone (1R,5R)-6,6-dimethylbicyclo[3.1.1]heptane-2,3-dione ("PinDione"). As both...

Systolic anterior motion of the mitral valve-the mechanism of postural hypotension following left intrapericardial pneumonectomy.

Journal of thoracic disease

Lasala JD, Tsai J, Rodriguez-Restrepo A, Atay SM, Sepesi B.
PMID: 28523177
J Thorac Dis. 2017 Apr;9(4):E354-E357. doi: 10.21037/jtd.2017.03.117.

Systolic anterior motion (SAM) is defined as displacement of the distal portion of the anterior leaflet of the mitral valve toward the left ventricular outflow tract obstruction. SAM can occur in patients without hypertrophic cardiomyopathy (HOCM) and is a...

Using Benford's law to investigate Natural Hazard dataset homogeneity.

Scientific reports

Joannes-Boyau R, Bodin T, Scheffers A, Sambridge M, May SM.
PMID: 26156060
Sci Rep. 2015 Jul 09;5:12046. doi: 10.1038/srep12046.

Working with a large temporal dataset spanning several decades often represents a challenging task, especially when the record is heterogeneous and incomplete. The use of statistical laws could potentially overcome these problems. Here we apply Benford's Law (also called...

Is Double-Blinded Peer Review Necessary? The Effect of Blinding on Review Quality.

Plastic and reconstructive surgery

Chung KC, Shauver MJ, Malay S, Zhong L, Weinstein A, Rohrich RJ.
PMID: 26273735
Plast Reconstr Surg. 2015 Dec;136(6):1369-1377. doi: 10.1097/PRS.0000000000001820.

BACKGROUND: The review process can be completely open, double-blinded, or somewhere in between. Double-blinded peer review, where neither the authors' nor peer reviewers' identities are shared with each other, is thought to be the fairest system, but there is...

Enhancing the hit-to-lead properties of lead optimization libraries.

Journal of chemical information and computer sciences

Pickett SD, McLay IM, Clark DE.
PMID: 10761127
J Chem Inf Comput Sci. 2000 Mar;40(2):263-72. doi: 10.1021/ci990261w.

In this paper we address several issues in the design of lead optimization libraries. Multipharmacophore descriptors were first developed in the context of designing diverse compound libraries. One reason for favoring such descriptors is the importance of the pharmacophore...

Virus Transmission Phenotype Is Correlated with Host Adaptation Among Genetically Diverse Populations of the Aphid Schizaphis graminum.

Phytopathology

Gray SM, Smith DM, Barbierri L, Burd J.
PMID: 18944022
Phytopathology. 2002 Sep;92(9):970-5. doi: 10.1094/PHYTO.2002.92.9.970.

ABSTRACT Schizaphis graminum is an important insect pest of several grain crops and an efficient vector of cereal-infecting luteoviruses and poleroviruses. We examined the virus transmission characteristics of several distinct populations and various developmental stages of the aphid. Seven...

Enzymatic activities of some snake venoms from families Elapidae and Viperidae.

Pakistan journal of pharmaceutical sciences

Alam JM, Qasim R, Alam SM.
PMID: 16414774
Pak J Pharm Sci. 1996 Jan;9(1):37-41.

Alkaline phosphomonoesterase, phosphodiesterase, L-amino acid oxidase, hyaluronidase, 5'-nucleotidase, arginine ester hydrolase, phospholipase A2 and proteinase activities were determined in eight snake venoms, including three from sea snake, of families Elapidae and Viperidae from Pakistan. The species includes three sea...

Rho signaling mediates cytoskeletal re-arrangements in octopus photoreceptors.

American malacological bulletin

Gray SM, Kelly S, Robles LJ.
PMID: 19865596
Am Malacol Bull. 2008 Dec 01;26(1):19-26. doi: 10.4003/006.026.0203.

Light sensitive rhabdoms in the octopus retina increase in cross-sectional area in the dark and shrink in the light. Growth in the dark is due to the formation of microvilli in an avillar region of the photoreceptor cell membrane...
