(IZCAS).</p> <p> <b>Etymology</b>. The specific epithet is a noun in apposition and refers to the type locality, which is commonly known as the “MacRitchie Forest” within the species-rich Central Catchment Nature Reserve in Singapore. The name of this forest is becoming a catch-phrase epitomizing an evolving habit towards constructive engagement, in the spirt of mutual respect, among government agencies, the scientific community and civil society seeking to finetune a balance between safeguarding the shared natural heritage of all Singaporeans and meeting the infrastructure needs in land-scarce Singapore.</p> <p> <b>Diagnosis.</b> The most diagnostic characteristic of the male <i>Ovia macritchie</i> <b>sp. nov.</b> is seen in the cymbium, with two irregular rows of bristles dorsally and without an apical claw (Fig. 2C). Palea with a conspicuous projection beyond the bulb. Terminal apophysis twisted basally and dagger-like distally. Tegular lobe triangular, with the tip of the bent, needle-like embolus resting on it (Fig. 8 A–D). Females of <i>Ovia macritchie</i> <b>sp. nov.</b> can be distinguished from <i>O. procurva</i> (Figs 6 E–F, 9E–F, 12C–D) by the sharply tapering epigynal hoods, smaller vulval chambers located over copulatory ducts and spermathecae far away from the anterior ends of the epigynal hoods (Fig. 8E, F). Femora I of mature males and females are black, while two longitudinal lateral bands run through the legs from the tibiae to metatarsi (Fig. 2 D–G). The carapace and to a lesser extent the dorsum of opisthosoma of live specimens are covered with setae that reflect a characteristic bluish, metallic sheen (Fig. 13 A–B).</p> <p> <b>Description.</b> <i>Male</i>.

Clarifying the charging induced nucleation in glass anode of Li-ion batteries and its enhanced performances
No full textIt was recently discovered that nanocrystals could be generated in glass anodes by Li-ion insertion, and thereby the cycling stability of Li-ion batteries was enhanced. Here we reveal the origins of both the nanocrystal formation and the enhancement of battery performances by exploring phase transitions, redox reactions, and structural heterogeneity in glass anodes. We infer that Li + ions interact with the higher energy domains of structural network during discharging/charging, and some of the Li ions are incorporated into the structural network, and thereby the potential energy is lowered through nanocrystal formation. Upon 5000 discharging/charging cycles at a high current density of 1 A g −1 , the nanocrystals in the 40TeO 2 –60V 2 O 5 glass were identified to be γ-Li 3 VO 4 . Owing to the metastable nature of the γ-Li 3 VO 4 phase, the glass anode becomes electrochemically active and highly ionic conductive. Simultaneously, the cycling stability is greatly enhanced by the nanostructured glass since the nanocrystals could suppress the propagation of micro-cracks generated by volume changes in glass matrix. </p
Toward a Unified Description of Isoscalar Giant Monopole Resonances in a Self-Consistent Quasiparticle-Vibration Coupling Approach
No full textThe nuclear incompressibility is a key parameter of the nuclear Equation of State (EoS) that can be extracted from the measurements of the so-called ``breathing mode'' of finite nuclei. The most serious discrepancy so far is between values extracted from Pb and Sn, that has provoked the longstanding question ``Why is tin so soft?".
To solve this puzzle, a fully self-consistent Quasiparticle Random-Phase Approximation (QRPA) plus Quasiparticle-Vibration Coupling (QPVC) approach based on Skyrme-Hartree-Fock-Bogoliubov is developed. We show that the many-body correlations introduced by QPVC, which shift the ISGMR energy in Sn isotopes by about 0.4 MeV more than the energy in Pb, play a crucial role in providing a unified description of the ISGMR in Sn and Pb isotopes. The best description of the experimental strength functions is given by SV-K226 and KDE0, which are characterized by incompressibility values 226 MeV and 229 MeV, respectively, at mean field level
