Three or more photovoltaic cell units connected in series include a unit holding a voltage between output terminals, a first voltage holding unit group having a voltage holding unit holding a voltage between an anode-side terminal and a cathode-side terminal for each photovoltaic cell unit set with respect to each set of the (2k+1)th and (2k+2)th photovoltaic cell units connected in series to each other counted from the anode side, and a second voltage holding unit group having a voltage holding unit holding a voltage between an anode-side terminal and a cathode-side terminal for each photovoltaic cell unit set with respect to each set of the (2k+2)th and (2k+3)th photovoltaic cell units connected in series to each other counted from the anode side.


The discovery of functional lateralization and localization of the brain marked the beginning of a new era in neuroscience. While the past 150. years of research have provided a great deal of knowledge of hemispheric differences and functional relationships, the precise organization of functional laterality remains a topic of intense debate. Here I will shed light on the functional organization of the two hemispheres by reviewing some of the most recent functional near-infrared spectroscopy (NIRS) studies that have reported hemispheric differences in activation patterns. Most NIRS studies using visual stimuli, which revealed functional differentiation between the hemispheres, have reported unilateral activation, i.e., significant levels of activation in only one hemisphere. Auditory stimuli, including speech sounds, elicited bilateral activation, while the limited number of studies on young infants revealed primarily unilateral activation. The stimulus modality and the age of the participants therefore determine whether the resulting cortical activation is unilateral or bilateral. By combining a review of the existing literature with NIRS results regarding homologous connectivity across hemispheres, I hypothesized that the origin of functional lateralization changes from the independence of each hemispheric region, to mutual inhibition between homologous regions during development. Future studies applying multi-modal measurements along with NIRS and spatiotemporal analyses will further deepen our understanding of the interhemispheric organization of brain function. © 2013 Elsevier Inc.

We present the latest version of the Molecular Evolutionary Genetics Analysis (Mega) software, which contains many sophisticated methods and tools for phylogenomics and phylomedicine. In this major upgrade, Mega has been optimized for use on 64-bit computing systems for analyzing larger datasets. Researchers can now explore and analyze tens of thousands of sequences in Mega The new version also provides an advanced wizard for building timetrees and includes a new functionality to automatically predict gene duplication events in gene family trees. The 64-bit Mega is made available in two interfaces: graphical and command line. The graphical user interface (GUI) is a native Microsoft Windows application that can also be used on Mac OS X. The command line Mega is available as native applications for Windows, Linux, and Mac OS X. They are intended for use in high-throughput and scripted analysis. Both versions are available from www.megasoftware.net free of charge. © The Author 2016. Published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution.

A method for generating a CPT resonance, includes applying an electric current to a laser light-emitting element, to emit laser light having at least two wavelengths. The value of a direct current component of the electric current applied to the laser light-emitting element in a first period is greater than an oscillation threshold for the laser light-emitting element, and the value of the direct current component of the electric current applied to the laser light-emitting element in a second period, following the first period, is less than the value of the direct current component of the electric current in the first period. An alkali metal atom is irradiated with the laser light, the laser light generated in the first period and the laser light generated in the second period entering the alkali metal atom repeatedly a plurality of times to generate a Ramsey resonance.

Reported examples of vanadium complexes employed as homogeneous catalyst precursors for olefin polymerization, including some of the recent efforts using (arylimido) vanadium(V) complex catalysts for precise olefin polymerization, are summarized. More recent examples for ethylene dimerization and ring-opening metathesis polymerization to demonstrate the unique characteristics of vanadium are also compiled. Use of thiobis(phenoxy) ligand in place of the dithiolato ligand improved the catalytic activity, and a complex showed remarkable catalytic activities in the presence of cocatalyst. arylimido)vanadium(IV) dichloride complexes has shown high catalytic activities for ethylene polymerization in the presence of Et2AlCl cocatalyst. Feher et al. reported that vanadium-containing silsesquioxane showed catalytic activity for ethylene polymerization in the presence of AlMe3 as the cocatalyst affording polymer with unimodal distribution.

In a circuit device controlling an operating point of each of two or more series-connected photovoltaic cells or other power supply cells in a module, the output voltage of the module can be boosted without reducing the generated electric power. The operating point control circuit device includes capacitors connected in parallel to the respective series-connected cells, switching elements connected in parallel to the respective series-connected cells through an inductor, an additional capacitor connected in series to the capacitor row, and an additional switching element connected in series to the switching element row. The switching elements are controlled to shut off electrical conduction between the corresponding terminals connected thereto in the same predetermined cycle and in mutually different periods so as to always establish a condition that one switching element is in the non-conductive state and the others are is in the conductive state.
