In this paper, we consider the fault Hamiltonicity, and the fault Hamiltonian connectivity of the (n, k)-star graph Sn,k. Assume that F V(Sn,k) E(Sn,k). For n k ≥ 2, we prove that Sn,k F is Hamiltonian if F ≤ n 3 and Sn,k F is Hamiltonian connected if F ≤ n 4. For n k 1, Sn,n 1 is isomorphic to the n-star graph Sn which is known to be Hamiltonian if and only if n > 2 and Hamiltonian connected i...

The formyl-meth-oxy-nitro-phenoxide ions in the polymeric title compound, [Sn(C(7)H(7))(3)(C(8)H(6)NO(5))](n), link adjacent triorganotin(IV) cations into linear chains lying close to (101) [Sn-O = 2.1227 (12) Å and Sn← O = 2.4936 (13) Å]. The Sn(IV) atom is displaced out of the C(3)Sn girdle of the trans-C(3)SnO(2) trigonal-bipyramidal polyhedron in the direction of the covalently-bonded O ato...

In this paper we will address the question of how many nonvanishing, linearly independent tangent vector fields can exist on a sphere Sn−1 ⊆ R. By this we mean the following, a tangent vector field on Sn−1 = {x ∈ R : ‖x‖ = 1} is a map v : Sn−1 → R such that v(x) ⊥ x for all x ∈ Sn−1. However, by assumption v is nonvanishing, so we can normalize such that ‖v(x)‖ = 1 and we obtain a map v : Sn−1 ...

A patterned coreeshell tin (Sn) nanorod anode is fabricated by pulse electrodeposition of Sn onto a selfassembled Tobacco Mosaic Virus (TMV) structured nickel current collector. Pulse electrodeposition onto the virus assembled 3D electrode surfaces produces homogenous Sn coatings with significant void space to accommodate the large volume change associated with Sn lithiation. The TMV enabled 3D...

Howell et al. have reported the discovery of SN Ia SN 2003fg (SNLS-03D3bb) and conclude that SN 2003fg is very likely a super-Chandrasekhar-mass SN Ia perhaps with a mass∼ 2M⊙. Their work is the first strong evidence that has been presented for a super-Chandrasekhar SN Ia. We have performed an analysis of the SN 2003fg data using the Yoon & Langer binding energy formula for a rotating super-Cha...

We present spectroscopic and extensive photometric observations of supernova (SN) 1998de in the S0 galaxy NGC 252, discovered during the course of the Lick Observatory Supernova Search. These data, which span a time period of 8 days before to 76 days after B-band maximum, unambiguously establish SN 1998de as a peculiar and subluminous type Ia supernova (SN Ia) with strong similarities to SN 199...

Supernova (SN) rates are a potentially powerful diagnostic of star formation history (SFH), metal enrichment, and SN physics, particularly in galaxy clusters with their deep, metal-retaining potentials and simple SFH. However, a low-redshift cluster SN rate has never been published. We derive the SN rate in galaxy clusters at 0:06 < z < 0:19, based on Type Ia supernovae (SNe Ia) that were disco...

CCD U BV RI photometry is presented for type IIn SN 2005kd. The maximum luminosity exceeded MV = −19.8, and SN remained brighter than −18 mag for about 400 days. While overall photometric evolution is quite similar to SN 1997cy, SN 2005kd shows a plateau at phases between 119 and 311 days past explosion, which is a unique feature for SN IIn.

Irinotecan (CPT-11) is a promising antitumor agent, recently approved for use in patients with metastatic colorectal cancer. Its active metabolite, SN-38, is glucuronidated by hepatic uridine diphosphate glucuronosyltransferases (UGTs). The major dose-limiting toxicity of irinotecan therapy is diarrhea, which is believed to be secondary to the biliary excretion of SN-38, the extent of which is ...

Cu₆Sn₅ whiskers precipitated in Sn3.0Ag0.5Cu/Cu interconnection in concentrator silicon solar cells solder layer were found and investigated after reflow soldering and during aging. Ag₃Sn fibers can be observed around Cu₆Sn₅ whiskers in the matrix microstructure, which can play an active effect on the reliability of interconnection. Different morphologies of Cu₆Sn₅ whiskers can be observed, and...
