To study the association of autoimmunity and human B cell neoplasia, we have established a model of a B cell lymphoma which expresses a pathogenic autoantibody of defined specificity. The Ig VH gene expressed in this neoplasm was analyzed longitudinally using clinical specimens taken from the splenic lymphoma (S) at diagnosis and from lymph node relapses 3 and 4 yr later (N3 and N4). Southern a...

The nonlinear coefficients, n4, of the time-dependent refractive index for argon are calculated in the non-resonant optical regime. Second-order polynomial fitting of DC-Kerr, γ((2))(-ω; ω, 0, 0), electric field induced second harmonic generation (ESHG), γ((2))(-2ω; ω, ω, 0), and static second-order hyperpolarizability, γ((2))(0; 0, 0, 0), is performed using an auxiliary electric field approach...

The objectives of the study were to determine distribution heavy metal contamination in water, sediments and biota (Callinectes amniciola) upper reaches Bonny Estuary impact on physicochemical characteristics water body. Sampled was from January June 2020. parameters varied slightly across months but within FEPA/WHO (2003) acceptable limits. Furthermore; compared seasonal variations determinati...

BACKGROUND The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties exhibiting natural genetic variation, and then elucidation of the underlying mechanisms of resistance. METHODOLOGY/PRINCIPAL FINDINGS BPH feeding behaviour was compared on 12 rice vari...

In [5] it is shown how a model for the logic of constructible duality is a symmetric monoidal closed category with products, that is, a model of linear logic. Remarkably, Nelson’s strong negation∼ behaves as linear duality ⊥. We compare it with some previous results from [4] regarding stable models in a linear logic setting, and suggest some further lines to explore. 1. From Ncd to linear logic...

We use a sequence of blow-ups over the projective space parametrizing plane curves of degree d to obtain some enumerative results concerning smooth plane curves of arbitrary degree. For d = 4 , this gives a first modem verification of results of H. G. Zeuthen. O. INTRODUCTION The kth 'characteristic number' of the d(dt3) -dimensional family of smooth plane curves of degree d, denoted Nd(k) in t...
