The design, synthesis, and electronic properties of a new series of D-π-A conjugates consisting of free base (H2P) and zinc porphyrins (ZnP) as electron donors and a fullerene (C60) as electron acceptor, in which the two electroactive entities are covalently linked through pyridine-vinylene spacers of different lengths, are described. Electronic interactions in the ground state were characteriz...

Recurrence and metastasis are commonly associated with poor prognosis of hepatocellular carcinoma (HCC). Therefore, a better understanding of molecular mechanisms involved in HCC metastasis may lead to more effective treatment for HCC patients. Rac plays important roles in cytoskeletal reorganization leading to cell motility in renal and breast carcinomas. However, the role of Rac is controvers...

We propose a family of high order methods for solution of hyperbolic conservation laws which are based on the discontinuous Galerkin (DG) spatial discretization. In the standard DG method, the dispersion and dissipation errors and the spectrum of the semi-discrete scheme are related to the [ p p+1 ] Padé approximants of exp(z) and exp(−z). These Padé approximants are responsible for the superco...

The fibronectin fragment, 9th-10th-type III domains (FIII9-10), mediates cell attachment and spreading and is commonly investigated as a bioadhesive interface for implant materials such as titania (TiO2). How the extent of the cell attachment-spreading response is related to the nature of the adsorbed protein layer is largely unknown. Here, the layer thickness and surface fraction of two FIII9-...

Abstract Objectives This study aimed to identify high-risk factors for high cardiac radiation exposure, based on anatomical measurements taken from planning CT images of patients with left-sided breast cancer who underwent breast-conserving surgery and received radiotherapy. Methods We retrospectively analyzed 45 whole-breast radiotherapy, either under free breathing (27/45) or deep inspiratory...

We characterize the boundaries of positive holomorphic chains in an arbitrary complex manifold. We then consider a compact oriented real submanifold of dimension 2p − 1 in a compact Kähler manifold X and address the question of which relative homology classes inH2p(X,M ; Z) are represented by positive holomorphic chains. Specifically, we define what it means for a class τ ∈ H2p(X,M ; Z) to be o...

We establish character sum bounds of the form ∣∣∣∣ ∑ a≤x≤a+H b≤y≤b+H χ(x + ky) ∣∣∣∣ < p−τH2, where χ is a nontrivial character (mod p), p 1 4 +ε < H < p, and |a|, |b| < p H. As an application, we obtain that given k ∈ Z\{0}, x + k is a quadratic non-residue (mod p) for some 1 ≤ x < p 1 2e. Introduction. Let k be a nonzero integer. Let p be a large prime and let H ≤ p. We are interested in the c...

MOTIVATION Nonlinear small datasets, which are characterized by low numbers of samples and very high numbers of measures, occur frequently in computational biology, and pose problems in their investigation. Unsupervised hybrid-two-phase (H2P) procedures-specifically dimension reduction (DR), coupled with clustering-provide valuable assistance, not only for unsupervised data classification, but ...

An In-depth analysis of the INT05 tritium-production—blanket design Is presented. A ternary system of solid silicate breeder, lead neutron multiplier, and graphite moderator is explored primarily from safety and blanket tritium-inventory considerations. Lithiumsilicate (Li2Si03) bleeder systems are studied along 2 with water (H2P/D2O) and Type 316 stainless steel as coolant and structural mater...
