In infected people, the HIV-1 envelope glycoprotein (Env) constantly evolves to escape the immune response while retaining the essential elements needed to mediate viral entry into target cells. The extensive genetic variation of Env is particularly striking in the V1/V2 hypervariable domains. In this study, we investigated the trade-off, in terms of fusion efficiency, for encoding V1/V2 domain...
A balanced bipartition of a graph G is a bipartition V1 and V2 of V (G) such that −1 ≤ |V1| − |V2| ≤ 1. Bollobás and Scott conjectured that if G is a graph with m edges and minimum degree at least 2 then G admits a balanced bipartition V1, V2 such that max{e(V1), e(V2)} ≤ m/3, where e(Vi) denotes the number of edges of G with both ends in Vi. In this note, we prove this conjecture for graphs wi...
To explore the role of visual area V2 in shape analysis, we studied the responses of neurons in area V2 of the alert macaque using a set of 128 grating and geometric line stimuli that varied in their shape characteristics and geometric complexity. Simple stimuli included oriented bars and sinusoidal gratings; complex stimuli included angles, arcs, circles, and intersecting lines, plus hyperboli...
If {A(V )} is a net of local von Neumann algebras satisfying standard axioms of algebraic relativistic quantum field theory and V1 and V2 are spacelike separated spacetime regions, then the system (A(V1),A(V2), φ) is said to satisfy the Weak Reichenbach’s Common Cause Principle iff for every pair of projections A ∈ A(V1), B ∈ A(V2) correlated in the normal state φ there exists a projection C be...
این مقاله به بررسی راهکارهای واجیِ زبان کردی سورانی برای جلوگیری از التقای واکهها میپردازد. دادههای التقای واکهها در کردی سورانی، متناسب با هدف پژوهش، جمعآوری و طبقهبندیشده و سپس در چارچوب واجشناسی بهینگی مورد تحلیل قرار گرفتند. بررسی و تحلیل دادههای واجی تحقیق نشان داد که در صورتی که در فرایند کلمهسازیِ کردی سورانی رشته واجی /V+V/ در مرز تکواژ ظاهر شود، بسته به شرایط واجی و صرفیِ زنجیر...
Spinal ventral interneurons regulate the activity of motor neurons, thereby controlling motor activities. Interneurons arise during embryonic development from distinct progenitor domains distributed orderly along the dorso-ventral axis of the neural tube. A single ventral progenitor population named p2 generates at least five V2 interneuron subsets. Whether the diversification of V2 precursors ...
BACKGROUND The gut mucosal homing integrin receptor α4β7 present on activated CD4+ T cells interacts with the HIV-1 gp120 second variable loop (V2). Case control analysis of the RV144 phase III vaccine trial demonstrated that plasma IgG binding antibodies specific to scaffolded proteins expressing the first and second variable regions (V1V2) of HIV envelope protein gp120 containing the α4β7 bin...
