No full text<i>Oryctopterus varuna</i> sp. nov. <p>urn:lsid:zoobank.org:act: 9E74ACC6-86D2-4A93-812A-5997835415D3</p> <p>Figs 1–39, 49–52, 70</p> Diagnosis <p> <i>Oryctopterus varuna</i> sp. nov. can be differentiated from <i>Ot. lagenipes</i> (Fig. 48) from Sri Lanka, by the following characters: (1) clypeus weakly narrowed ventrally in <i>Ot. varuna</i> sp. nov., more strongly narrowed ventrally in <i>Ot. lagenipes</i>, (2) first foretarsomere about 1.4 times as long as the rest combined in <i>Ot. varuna</i> sp. nov., 2.4 times as long as the rest combined in <i>Ot. lagenipes</i>, (3) hindwings fully developed in <i>Ot. lagenipes</i> (Fig. 48) (much reduced in <i>Ot. varuna</i> sp. nov.: Figs 1–2, 10–12). <i>Oryctopterus varuna</i> sp. nov. can be differentiated from <i>Ot. yeshwanthi</i> sp. nov. based on the structure of the mandible, pronotum and female genitalia, as mentioned under the latter species.</p> Etymology <p> The new species is named after Varuna, the god of rains in Indian mythology. The name is a noun in apposition. This cricket was observed coming out to open areas such as campus roads following rains, hence the name. In the regional dialect, <i>Ot. varuna</i> sp. nov. is called ‘ <i>Mannunni</i> ’, meaning ‘child of soil’. Also nicknamed ‘ <i>Thanni-Pillai</i> ’, meaning ‘baby of water’, alluding to its emergence following rains.</p> Type material <p> <b>Holotype</b> INDIA • ♂; Kerala, College of Agriculture, Vellayani; 18 Mar. 2021; Kumar A. leg.; “HOLOTYPE; <i>Oryctopterus varuna</i> sp. nov.; des.

Claws of forelegs well developed in male, absent in female. Spines on metatibia well developed and sharp in male, much reduced or hardly discernible in the female.</p> Remarks <p> <i>Oryctopterus varuna</i> sp. nov. and <i>Ot. lagenipes</i> were geographically isolated multiple times in the Quarternary and most recently during the separation of Sri Lanka from south India, around 7500 years ago with the Holocene rises in sea level (Gunatilaka 2000). Poorly developed hind wings indicate that <i>Ot. varuna</i> sp. nov. could be flightless, despite being alate. Wing venation varies considerably, in the branching pattern, shape of veins and cross veins (Figs 10–12). Béthoux (2012) showed that in king crickets, raspy crickets and weta, wing venation vary greatly within species and several species delimited based on wing venation are synonyms. Ross (2012), who studied cockroaches, proved that forewings of a cockroach species vary considerably; even the left and right wings on the same specimen are slightly different. According to Ross (2012), since forewings in cockroaches are not used for active flight, the positions of the veins, which are important for the aerodynamics and flexing of the wings, vary greatly. The intraspecific variation in the wing venation in <i>Oryctopterus</i>, could be the outcome of a flightless, subterranean mode of life.</p> <p> <i>Oryctopterus varuna</i> sp. nov. is only known from the Vellayani campus of the Kerala Agricultural University (8°25′46.3″ N, 76°59′07.8″ E, 39 m elevation). Description of this new species underscores the importance of biodiversity conservation in periurban areas, as reckless development is taking its toll on all life forms in every imaginable habitat, throughout India and elsewhere.</p> Notes on biology <p> <b>Female reproductive system</b></p> <p>Ovaries were paired and each ovary (Fig. 37) consists of more than 10 panoistic ovarioles, each ovariole containing about six eggs (Fig. 38). A total of about 175– 200 eggs were present inside the ovaries of an individual. Mature eggs are lemon-shaped (Fig. 39). Fully developed eggs in the ovary indicate that the dissected as well as the other examined specimens, which are morphologically identical, are probably all adults.</p> <p> <b>Habitat</b></p> <p> Vellayani campus of the Kerala Agricultural University is the sole known habitat of the new species. The total area of the campus is about 2.52 km 2. This is a highly populated residential area and the open lands are under cultivation with various agricultural crops. Chemical fertilizers and pesticides are used to raise the crops. The campus has a network of roads connecting academic and residential buildings and other facilities. The soil type is red loam and the average annual rainfall is 1577 mm.</p> <p> <b>Seasonality</b></p> <p> Most females were seen walking on the open campus roads during or after a downpour, both during day and night. One individual was caught around midday on 8 September 2019, when it was bright and sunny. Emergence of females of <i>Ot. varuna</i> sp. nov. coincides with the south-west monsoon rains during June to September. However, males are extremely rare and two individuals were collected following summer rains during the peak summer of March 2021.</p> <p> <b>Food habits as indicated by the gut contents</b> (Figs 40–47)</p> <p> Examination of the gut contents of three of the specimens revealed the presence of mandibles of mandibulate soldiers (Figs 40–41) and workers (Fig. 42) of the termite <i>Odontotermes</i> sp. (Blattaria, Termitidae); and the body parts, including head (Fig. 43), thorax (Figs 44–45), and abdomen of ants (probably <i>Pheidole</i> sp., Hymenoptera, Formicidae). Interestingly, a piece of the stem of a plant (0.58 mm × 0.43 mm) (Fig. 46) and sand particles (0.24–0.62 mm diameter) (Fig. 47) were also observed inside the gut.</p> <p> <b>Behavior</b></p> <p> The new species is a ‘heel-walker’ (Fig. 49, Supp. file 3). They walk on the distal tip of tibiae with the foretarsi always held raised, while the mid- and hind tarsi are in close proximity to the ground, yet not touching it while walking. However, when not moving, all the tarsi may touch the ground. While walking, the long maxillary palpi are held forward and constantly touch the objects in the foreground in tandem. South African Jerusalem Crickets are known to hop and climb vegetation (Weissman & Bazelet 2013) while some of the New World species exhibit drumming (abdomen striking against the substrate) (Weissman 2001a). However, no such behaviors were observed in <i>O. varuna</i> sp. nov. When a female was held above the ground level on a flat substrate, it rather tumbled down instead of hopping. It also failed to climb up sticks on which it was placed. A male was observed flapping wings and performing short jumps of about 0.3 m.</p> <p> <b>Defense</b></p> <p> <i>Oryctopterus varuna</i> sp. nov. displayed intricate defensive postures when intimidated. Confronted from the front, the cricket sprang into a pouncing posture, raised its forelegs and waved in mid-air, the mandibles opened widely, as if ready to bite (Fig. 50, Supp. file 1). When approached from the anterolateral side, it raised the front leg on that side to defend. However, when the animal was poked on the thorax, in addition to the forelegs, the abdomen also was raised, to startle the attacker (Fig. 51). When an individual is pinned down with the index finger firmly pressed on the thorax, the whole body was flexed and all legs were raised and started kicking to fend off the assailant. They inflicted painful bites when handled. Weissman (2001a) reported that New World Stenopelmatine, when confronted, frequently flip on their back, with mandibles agape, or can rear up.</p> <p> <b>Burrowing</b></p> <p> Burrowing was observed by releasing an adult female into a 23.50 cm high, 21.50 cm wide polypropylene tub filled with loose soil up to <b>⅔</b> the height of the tub. Mainly head and legs are used in burrowing. To begin with, the forelegs were firmly held against the ground to anchor the body, then the head was bent down, moving forward and backward to dig up the soil, with the mandibles acting like a shovel (Fig. 52, Supp. file 2). The dug-up soil was then pushed backwards and sideways with hindlegs and midlegs respectively. In the laboratory, it made a burrow that was vertical initially but turned oblique, then horizontal and nearly parallel to the surface. Observed behavior suggests that the Oryctopinae are subterranean, inhabiting underground burrows.</p>Published as part of <i>Hiremath, S. R. & Prathapan, K.

Study of the decay mechanism for B+ -> p(p)over-barK(+) and B+ -> p(p)over-bar pi(+)
No full textWe study the characteristics of the low mass p (p) over bar enhancements near threshold in the three-body decays B+ -> p (p) over barK(+) and B+ -> p (p) over bar pi(+). We observe that the proton polar angle distributions in the p (p) over bar helicity frame in the two decays have the opposite polarity, and measure the forward-backward asymmetries as a function of the p mass for the p (p) over barK(+) mode. We also search for the intermediate two-body decays, B+ -> (p) over bar Delta(++) and B+ -> p (Delta) over bar (0), and set upper limits on their branching fractions. These results are obtained from a 414 fb(-1) data sample that contains 449 x 10(6) B (B) over bar events collected near the Gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations

Measurement of the CKM angle gamma from a combination of B->Dh analyses
No full textA combination of three LHCb measurements of the CKM angle gamma is presented. The decays B->DK and B->Dpi are used, where D denotes an admixture of D0 and D0-bar mesons, decaying into K+K-, pi+pi-, K+-pi-+, K+-pi-+pi+-pi-+, KSpi+pi-, or KSK+K- final states. All measurements use a dataset corresponding to 1.0 fb-1 of integrated luminosity. Combining results from B->DK decays alone a best-fit value of gamma = 72.0 deg is found, and confidence intervals are set gamma in [56.4,86.7] deg at 68% CL, gamma in [42.6,99.6] deg at 95% CL. The best-fit value of gamma found from a combination of results from B->Dpi decays alone, is gamma = 18.9 deg, and the confidence intervals gamma in [7.4,99.2] deg or [167.9,176.4] deg at 68% CL, are set, without constraint at 95% CL. The combination of results from B->DK and B->Dpi decays gives a best-fit value of gamma = 72.6 deg and the confidence intervals gamma in [55.4,82.3] deg at 68% CL, gamma in [40.2,92.7] deg at 95% CL are set. All values are expressed modulo 180 deg, and are obtained taking into account the effect of D0-D0bar mixing
