No full textBackground- Sports is a wide field which requires intense practice to perform well; moreover athletes are always goal-oriented and put a lot of effort to win. This pressure and emotional distress lead to pre-competitive anxiety which affect their cognitive performance.
Purpose- The prime aim of this study is to evaluate the effect of tDCS on pre-competitive anxiety and cognitive performance in collegiate athletes.
Method/Design- The experimental study is randomized controlled trial, two group and single centered study. Anxiety and cognitive levels will be evaluated before and after intervention using Beck Anxiety Inventory (BAI) scales, stroop color test, digit symbol substitute test and biofeedback analysis (EMG). The experimental group and control group received tDCS for 10 consecutive days. Follow up assessment will be performance using post value of anxiety and cognitive scales and also by biofeedback analysis.
Results- The within group analysis of experiment group revealed P < 0.05 of beck anxiety inventory test, stroop test, DSST-test and EMG biofeedback. There is significant difference in between group analysis, the post value of Stroop test, DSST test and EMG biofeedback are less than0.05.
Conclusion- We concluded that the tDCS show positive effect on pre-competitive anxiety and cognitive performance of collegiate athletes. Anxiety and cognition can be controlled by using an advance mode of technique i.e., transcranial direct current stimulation (tDCS) it is the safe neurostimulation process used to improve athletic performance

Katha volynkini Joshi & Singh & Singh 2018, sp. nov.
No full textKatha volynkini Joshi & Singh, sp. nov. (Figs. 1, 13–14) Type locality: Garampani, Meghalaya, India. Type material: Holotype, ♂, INDIA, Meghalaya, Garampani, 09.IX.09 (Coll. R Joshi; Reg. no. PUP /RJ/135). One paratype: INDIA, Mizoram, Champhai, 27.IX.09 – 1♂.(Coll. R. Joshi; Reg. no. PUP/RJ/135a). Description: Adult (Fig. 1). Forewing length 14mm.Head with frons brown; vertex yellow. Antennae simple, brown. Labial palpi yellow, black at tips. Thorax with patagia and tegulae dark yellow; pectus pale yellow. Forewing creamish yellow with velvety texture; apex with more tinge of yellow; a deep groove from base of cell to tornus; underside minutely suffused with fuscous, termen pale; inner margin excurved at subbasal area. Hindwing concolourous. Legs black, suffused with some yellow on forelegs. Abdomen yellowish with some white at base. Male genitalia(Fig. 13) with uncus broad, sparsely setose, apically hooked; tegumen smaller than the very long vinculum; saccus deep v-shaped, with knob-like tip. Valvae typical of the genus, distal saccular process ending in a small spine. Juxta rectangular. Aedeagus (Fig. 14) moderately short and broad; vesica four lobed, apical lobe with female shoe shaped spine and basal lobe with a stout, blade-like spine; one lateral lobe with a dentate sclerotized plate, another with a field of minute spines. Diagnosis: Externally, the species of Katha are very similar to each other and are better diagnosed on the basis of male genitalia. Due to the absence of apical spine in aedeagus, and presence of two spines and a dentate plate in vesica, K. volynkini sp. nov. (Figs. 1, 13–14) is closely similar to K. conformis (Figs. 2, 15–16) but can be distinguished from it in the following attributes: a field of minute spines on a lobe opposite to the dentate plate is present; apical lobe of vesica is short with a female shoe shaped apical spine, vinculum broad “v”-shaped and saccus knobbed. Whereas, K. conformis lacks the field of minute spines, characteristic for the new species; the apical lobe of vesica is tubular with a nail like apical spine; the vinculum is narrow, “v”-shaped and the saccus is simple. Other closely related species is K. suffusa, which differs from the new species in the presence of single spine in vesica. Etymology: The species name is dedicated to Dr. Anton Volynkin, Arctiinae specialist from Tomsk, Russia.Published as part of Joshi, Rahul, Singh, Navneet & Singh, Jagbir, 2018, Description of a new Katha species from India, with a key to the Oriental species (Lepidoptera, Erebidae, Arctiinae), pp. 435-442 in Zootaxa 4407 (3) on page 436, DOI: 10.11646/zootaxa.4407.3.10, http://zenodo.org/record/121652

Strained SOI FINFET SRAM design
No full textImpact of strained silicon effects in double-gated FinFET structures on static random access memory (SRAM) cell functionality is presented. Three FinFET silicon-on-insulator (SOI) SRAM cell embodiments representing unstrained, strained, and NFET-only-strained devices are compared against a planar PDSOI SRAM cell design. The metrics encompass both static and dynamic behavior of the cell and are analyzed through 2-D process hardware-calibrated device models (Lg = 25 nm). The key findings of this letter are: 1) PFET devices with tensile strain are found to degrade the FinFET cell Read Noise Margin and cell ability to write a strong 1; 2) by restricting the tensile strain to the NFET devices FinFET SRAM cell Read stability and access times improve by 10percent-20percent relative to their unstrained FinFET and NFET-only strained PDSOI counterparts. © 1980-2012 IEEE.[Anonymous], 2006, TAUR TSUPREM 4 VERS; BASKER VS, 2010, P S VLSI TECHN, P19; Buturla E., 1989, P NASECODE 6, P291; Joshi R, 2006, PROC EUR S-STATE DEV, P315; Joshi R., 2005, U.

Geobacter sulfurreducens inner membrane cytochrome transcriptional and phenotypic data
No full textThe data files include raw data as well as analyzed results for transcriptional analysis of WT G. sulfurreducens and mutant lacking BccR (GSU0598) under fumarate vs iron citrate growth conditions. This dataset also includes the phenotypic data files for experiments associated with this project.Geobacter sulfurreducens utilizes extracellular electron acceptors such as Mn(IV), Fe(III), syntrophic partners, and electrodes that vary from +0.4 to −0.3 V vs. Standard Hydrogen Electrode (SHE), representing a potential energy span that should require a highly branched electron transfer chain. Here we describe CbcBA, a bc-type cytochrome essential near the thermodynamic limit of respiration when acetate is the electron donor. Mutants lacking cbcBA ceased Fe(III) reduction at −0.21 V vs. SHE, could not transfer electrons to electrodes between −0.21 and −0.28 V, and could not reduce the final 10% – 35% of Fe(III) minerals. As redox potential decreased during Fe(III) reduction, cbcBA was induced with the aid of the regulator BccR to become one of the most highly expressed genes in G. sulfurreducens. Growth yield (CFU/mM Fe(II)) was 112% of WT in ∆cbcBA, and deletion of cbcL (an unrelated bc-cytochrome essential near −0.15 V) in ΔcbcBA increased yield to 220%. Together with ImcH, which is required at high redox potentials, CbcBA represents a third cytoplasmic membrane oxidoreductase in G. sulfurreducens. This expanding list shows how metal-reducing bacteria may constantly sense redox potential to adjust growth efficiency in changing environments.Office of Naval Research: N00014-16-1-2194, and N00014-18-1-2632.Joshi, Komal; Chan, Chi Ho; Bond, Daniel R.

Tuning Transitions in Rotating Rayleigh-Bénard Turbulence
No full textRayleigh-Bénard convection is a canonical system for the investigation of buoyancy-driven natural convection phenomena which abound in nature and technology. Under the influence of rotation and depending on the system parameters, the flow exhibits different regimes with disparate heat transfer characteristics even in the turbulent state. The present study attempts to tune the transitions between these regimes and thus control the heat transfer in practical applications. In particular, we explore the effect of addition of neutrally-buoyant thermally-conducting particles to the fluid. Following an experimental approach, we study the flow structure and heat transfer as functions of particle concentration and system parameters

The colonies of aphids were found feeding on upper and lower surface of leaves of Phyllostachys sp. (Poaceae). Leaves with dense colonies were seen to have turned yellowish indicating the damage caused by continuous sucking of the sap. The life cycle is unknown. Taxonomic comments. Only one species of the genus Kaochiaoja Tao, viz., Kaochiaoja arthraxonis (Takahashi) was hitherto known, first described by Takahashi (1921) under the name Myzus arthraxoni. Tao (1963) erected the genus Kaochiaoja for this species. Later, Ghosh et al. 1970 described Micromyzus granotiae Ghosh, Ghosh and Raychaudhuri from India, and Miyazaki (1971) transferred Macrosiphum pollinae (Shinji) described from Japan to Kaochiaoja, with a redescription. Both these names have been synonymised with K. arthraxonis (Eastop and Blackman 2005; Remaudière and Remaudière 1997). Takahashi (1921) provided description of both apterous and alate viviparous females but Ghosh et al. 1970, and Miyazaki (1971) described only apterous viviparous females. Apterae from Arthraxon in Taiwan were described as shining dark brown with yellowish brown head (original description) while those described as Micromyzus granotiae (from Granotia sp.?) from West Bengal (Ghosh et al. 1970) also have a dusky head and are said to be dark brown in life with a coating of wax. However, apterae of Japanese populations on various Poaceae (e.g. Microstegium, Digitaria) are described as salmon pink to reddish brown in life, with a black head and dorsal abdominal patch (Miyazaki, 1971). The apterous viviparous females of the new species are shining black with dusky head and appendages, and the nymphs are light green with dark red eyes. No wax deposits were observed on dorsum or venter of apterous and alate viviparous females. K. arthraxonis K. sikkimensis sp.n. Takahashi (1921) did not describe an abdominal dorsal patch in the apterous viviparous female of K. arthraxonis, but stated that there was a very large patch between the siphunculi of the alate viviparous female. In all the Indian and Japanese apterae of K. arthraxonis examined, the abdominal dorsal patch was consistent in extent, reaching from the metanotum to the fourth abdominal segment, its borders ill-defined but leaving broad unpigmented areas laterally and anterior to the siphunculi, and with a medial division on the anterior abdominal segments broadening into a clear triangular window on segments 3 and 4 (fig. 5A). A distinctive feature of this dorsal sclerite is its rugose ornamentation, described by Miyazaki (1971) as “wart-like areolations” (fig. 5B). A separate sclerite extends behind the siphunculi across abdominal tergites 6 and 7. In K. sikkimensis the dorsal In other respects apterae of the new species are similar to K. arthraxonis, the only other detectable differences being in the pigmentation of the siphunculi and the shape and length of the cauda. The siphunculi of K. arthraxonis are mainly pale with only dusky base and apex, whereas those of the new species have more extensive and contrastingly darker basal and distal regions. The cauda of K. arthraxonis is relatively longer and tapers gradually from base to apex, whereas that of K. sikkimensis is finger-like, with sides that are parallel for most of length and only taper distally. Ratios involving the cauda (cauda/body length, cauda/ ANT III, cauda/ SIPH) are discriminatory between the two species (see Table 1). The new species will run to Melanaphis bambusae in couplet number 5 of the key to aphids occurring on Phyllostachys spp. by Blackman and Eastop (1994) but can easily be separated from that species which has short and truncate siphunculi about equal in length to the cauda, whereas in K. sikkimensis the siphunculi are tubular and much longer than the cauda.Published as part of Joshi, Sunil & Blackman, R.
