A standardized workflow for long-term longitudinal actigraphy data processing using one year of continuous actigraphy from the CAN-BIND Wellness Monitoring Study.

Monitoring sleep and activity through wearable devices such as wrist-worn actigraphs has the potential for long-term measurement in the individual's own environment. Long periods of data collection require a complex approach, including standardized pre-processing and data trimming, and robust algorithms to address non-wear and missing data. In this study, we used a data-driven approach to quality control, pre-processing and analysis of longitudinal actigraphy data collected over the course of 1 year in a sample of 95 participants.

Alfalfa response to heat stress is modulated by microRNA156.

Heat stress and extreme temperatures negatively affect plant development by disrupting regular cellular and biochemical functions, ultimately leading to reduced crop production. Alfalfa (Medicago sativa) is an important forage crop grown worldwide as forage for livestock feed. Limiting the effects of abiotic stress by developing alfalfa cultivars that are stress tolerant would help mitigate losses to crop production.

Physician assistant education in Germany.

The first physician assistant (PA) program in Germany began in 2005. As of 2013 there are three PA programs operational, with a fourth to be inaugurated in the fall of 2013. The programs have produced approximately 100 graduates, all with a nursing background.

Mixed valence Mn(II)/Mn(III) [3 x 3] grid complexes: structural, electrochemical, spectroscopic, and magnetic properties.

Mn(II)9 grid complexes with a [Mn9(mu-O)12] core, obtained by self-assembly of a series of tritopic picolinic dihydrazone ligands with Mn(II) salts, have been oxidized by both chemical and electrochemical methods to produce mixed oxidation state systems. Examples involving [Mn(III)3Mn(II)6] and [Mn(III)4Mn(II)5] combinations have been produced. Structures are reported for [Mn9(2poap-2H)6](NO3)6.

Crystal structures of dicarboxy-2,2'-bipyridyl complexes: the role of hydrogen bonding and stacking interactions.

The crystal structures of three complexes of dicarboxy-2,2'-bipyridyl ligands, 5,5'-dicarboxy-2,2'-bipyridyl (1) and 4,4'-dicarboxy-2,2'-bipyridyl (2) are reported. [Rh(1H)3] shows two interpenetrating, homochiral rhombohedral networks linked by short carboxylate-carboxylic acid hydrogen bonds, in which each complex acts as a node for six hydrogen bonds. [Ru(1H2)(1H)2] forms only four such hydrogen bonds, leading to the formation of heterochiral chains held together by stacking between bipyridyls.

Self-assembly of a unique hexadecanuclear [4 x (2 x 2)]-Pb16 'grid of grids' type structure.

A new ligand containing a linear sequence of four-tridentate chelating subunits built around alkoxide and pyrimidine bridging groups undergoes a spontaneous self-assembly process with Pb(CF3SO3)2 to produce a unique hexadecanuclear [4 x (2 x 2)] 'grid of grids' type structure with external dimensions of 26 A.

Synthesis, structure and magnetism of a unique dodecanuclearcopper(II) 'picture frame' held in a 4 x 4 grid-like assembly.

The synthesis, structure and preliminary magnetic studies of a novel dodecanuclearcopper(II) grid-like assembly are reported.
