We consider a (semi-)relativistic spin-1/2 particle interacting with quantized radiation. The Hamiltonian has the form Ĥ c := {c2[(p + A) +σ ·B] + (mc2)2}1/2 −mc2 +V +Hf . Assuming that the potential |V | is bounded with respect to the momentum |p|, we show that Ĥ c converges in norm-resolvent sense to the usual Pauli-Fierz operator when c, the speed of light, tends to ∞.

Objective(s): Heart failure (HF) is one of the leading causes of death worldwide. Due to beneficial effects of stem cells, paracrine secretion of them has recently been used by researchers. The purpose of this study was to investigate the effects of intravenous injection (IV) of conditioned medium (CM) of human amniotic membrane-derived mesenchymal stem cell (MSC-CM) o...

1. SK channels are small-conductance calcium-activated potassium channels that are widely expressed in neurons. The traditional view of the functional role of SK channels is in mediating one component of the after-hyperpolarization that follows action potentials. Calcium influx via voltage-gated calcium channels active during action potentials opens SK channels and the resultant hyperpolarizati...

Sulfakinins (SKs) are a family of multifunctional neuropeptides that have been shown to have myotropic activity on muscles of the digestive system and to function as feeding satiety factors. Here, we confirm via cloning the presence of two sulfakinins (Rhopr-SK-1 and Rhopr-SK-2) in Rhodnius prolixus. Reverse transcriptase quantitative PCR demonstrates that the Rhopr-SK transcript is highly expr...

Let sk = 1 √ N (v1k, . . . , vNk) T , k = 1, . . . ,K, where {vik, i, k = 1, . . .} are independent and identically distributed random variables with Ev11 = 0 and Ev 2 11 = 1. Let Sk = (s1, . . . , sk−1, sk+1, . . . , sK), Pk = diag(p1, . . . , pk−1, pk+1, . . . , pK) and βk = pks T k (SkPkS T k + σ 2 I)sk, where pk ≥ 0 and the βk is referred to as the signal-to-interference ratio (SIR) of user...

1.1 Small and semismall maps Let f : X → Y be a proper surjective map of varieties with X nonsingular. We say that a decomposition of Y = ⊔ k Sk into finitely many non-singular locally closed subvarieties Sk is a stratification relative to f if each restriction f : f(Sk)→ Sk is a topological locally trivial fibration. Proposition 1.1. The following conditions are equivalent. (a) Rf∗CX [dimX] is...

In 2001, Boneh and Franklin presented the first efficient and security-proved identity-based encryption scheme using pairing on elliptic curve. In 2003 Sakai and Kasahara proposed another IBE scheme with pairing, which has the potential to improve performance. Later, Chen and Cheng proved the security of a variant of Sakai and Kasahara’s scheme. While, both the security-provable schemes employ ...
