We give predictions for the ratio RQ(x,Q2)=FLQ(x,Q2)/F2Q(x,Q2) at small values of Bjorken variable x in first three orders perturbation theory. show an approximate x-independence RQ(x,Q2) low and non-large Q2 (Q2 < 8--10 m2Q), irrespectively on gluon density a proton used calculations. This observation could be useful subsequent phenomenological studies heavy flavor production future lepton-had...

Enquiry service online at www.ptemagazine.com I 1 Oral absorption efficiency can be influenced by several factors, acting independently or in concert. These include the physicochemical properties of the administered agent, human physiology, pathology (including disease state), the way the drug is presented (formulated) and possibly the amount that is administered (dose). Other influences includ...

In this paper, we give characterizations of the classical generalized quadrangles H(3, q2) and H(4, q2), embedded in PG(3, q2) and PG(4, q2), respectively. The intersection numbers with lines and planes characterize H(3, q2), and H(4, q2) is characterized by its intersection numbers with planes and solids. This result is then extended to characterize all hermitian varieties in dimension at leas...

We find and study a five-parameter family of four-dimensional partial differential systems in two variables from the viewpoints of its symmetry and holomorphy properties. 1. Main results In this paper, we present a 5-parameter family of four-dimensional partial differential systems in two variables explicitly given by (cf. [3, 18]) dq1 = ∂H1 ∂p1 dt+ ∂H2 ∂p1 ds, dp1 = − ∂H1 ∂q1 dt− ∂H2 ∂q1 ds, d...

A reanalysis of the model for longitudinal structure function FL(x,Q2) at low x and Q2 was undertaken, in view advent EIC. The is based on photon-gluon fusion mechanism suitably extrapolated to region Q2. It includes kinematic constraint FL∼Q4 as Q2→ 0 higher twist contribution which vanishes Q2→∞. Revised critically updated compared presently available data.

The spring season was the target for Nansen Legacy cruise organized in late April and first half of May 2021 following transect defined this series cruises to capture variations year sampling physical, biological chemical conditions ice sea. went through both open water ice. Seven process stations were visited (P1 P7) together with smaller NLEG according program seasonal investigations. station...

We characterize the finite Veronesean Hn ⊆ PG(n(n + 2), q) of all Hermitian varieties of PG(n, q2) as the unique representation of PG(n, q2) in PG(d, q), d≥n(n+2), where points and lines of PG(n, q2) are represented by points and ovoids of solids, respectively, of PG(d, q), with the only condition that the point set of PG(d, q) corresponding to the point set of PG(n, q2) generates PG(d, q). Usi...
