1 + cos2 φ). The boundary conditions for the wavefunction on the borders of the domain can be derived from Eqs. (S2-S3). The set of four equations (S4-S5) is solved numerically by using the adiabatic hyperspherical approach. Namely, we first diagonalize the hyperspherical part, i.e., we fix Π and in the kinetic energy operator (S6) we keep only the second line. We choose a grid which has many p...

Unusual CoS(2) ellipsoids with anisotropic tube-like cavities have been synthesized from the simultaneous thermal decomposition and sulfidation of a preformed cobalt carbonate precursor. The as-prepared CoS(2) ellipsoids show interesting supercapacitive properties with high capacitance and good cycling performance.

Insights into the cobalt sulfide formation upon sulfidation (10 % H2S/H2) of cobalt-based materials with 4 wt CoO supported on alumina or silica were obtained by Quick-X-ray absorption spectroscopy monitoring analysed multivariate curve regression analysis. A common pathway is evidenced involving defective CoS2 species transformed around 200−250 °C Co9S8 species. Upon cooling down under sulfidi...

We provide complete analytic expressions for the inclusive prompt photon production cross section in hadronic final states of e+e− annihilation reactions through one-loop order in quantum chromodynamics perturbation theory. Computed explicitly are direct photon production through first order in the electromagnetic strength αem and the quark-to-photon and gluon-tophoton fragmentation contributio...

The Hedgehog (Hh) signaling pathway plays multiple essential roles during metazoan development, homeostasis, and disease. Although core protein components are highly conserved, the variations in Hh signal transduction mechanisms exhibited by existing model systems (Drosophila, fish, and mammals) are difficult to understand. We characterized the Hh pathway in planarians. Hh signaling is essentia...

We present the first measurement of the angular distribution for the exclusive process p̄p→ ψ(2S) → e+e− based on a sample of 6844 events collected by the Fermilab E835 experiment. We find that the angular distribution is well described by the expected functional form dN d cos θ ∝ 1 + λ cos2 θ∗, where θ∗ is the angle between the Preprint submitted to Elsevier Science 7 February 2008 antiproton a...

A [CO]HN(CA)CB-E.COSY pulse scheme is described for measurement of three-bond couplings, 3JC'C beta, between carbonyl and aliphatic C beta carbons in ubiquitin, uniformly enriched with 13C and 15N. A Karplus relation, 3JC'C beta = 1.28 cos2(phi - 120 degrees) -1.02 cos(phi - 120 degrees) + 0.30 Hz, is obtained by correlating the 3JC'C beta values measured for human ubiquitin with backbone phi a...

Hedgehog (Hh) signaling is a key regulatory pathway during development and also has a functional role in mature neurons. Here, we show that Hh signaling regulates the odor response in adult Drosophila olfactory sensory neurons (OSNs). We demonstrate that this is achieved by regulating odorant receptor (OR) transport to and within the primary cilium in OSN neurons. Regulation relies on ciliary l...

This article describes two mathematical formalisms for the determination of the second and fourth order parameters of molecular films using optical spectroscopy. Method A uses polarized total internal reflection fluorescence (TIRF) to calculate the second and fourth order parameters, {P2(cos theta)} and {P4(cos theta)}, using an independently determined value for the angle between the absorptio...
