Low-Q2 photons do not resolve partons in the proton, which gives problems when applying the deep inelastic scattering formalism, such as an unphysical, negative gluon density extracted from data. Considering instead hadronic fluctuations of the photon, we show that the generalised vector meson dominance model (GVDM) gives a good description of the measured cross section at low Q2, i.e. reproduc...

We calculate the quarkonic O(?s2) massive operator matrix elements ?AQg(N),?AQqPS(N) and ?Aqq,QNS(N) for twist–2 operators associated heavy flavor Wilson coefficients in polarized deeply inelastic scattering region Q2?m2 to O(?) case of inclusive contributions. The evaluation is performed Mellin space, without applying integration-by-parts method. result given terms harmonic sums. This leads a ...

We analyze a well known type of puzzle in planar geometry: given a planar shape, it is required to find a cut that divides the shape into two identical parts (up to rotation and translation). Clearly not all shapes can be so dissected and for some shapes that appear in puzzles the cutting curve is quite surprising and difficult to find. In this paper we first analyze the inverse problem of asse...

The interactions between the boreal summer intraseasonal oscillation (ISO) and synoptic-scale variability (SSV) are investigated by diagnosing the atmospheric apparent heat source (Q1), apparent moisture sink (Q2), and eddy momentum transport. It is found that the synoptic Q1 and Q2 heating (cooling) anomalies are in phase with cyclonic (anticyclonic) vorticity disturbances, aligned in a southe...

JNJ-Q2 is a broad-spectrum fluoroquinolone with activity against Gram-positive and -negative pathogens. The in vitro activity of JNJ-Q2 was evaluated when tested against Neisseria gonorrhoeae isolates, including 31 ciprofloxacin-resistant strains with documented mutations in the quinolone resistance determining region. MIC values were determined using reference agar dilution methods using cipro...

We reanalyzed high quality spectra of 158 stars of spectral types A0–F1 and v sin i between 60 and 150 km s−1. Using a Least Squares Deconvolution technique we extracted high S/N broadening profiles and determined the loci of the Fourier transform zeros q1 and q2 where the S/N-ratio was high enough. The values of v sin i were redetermined and found to be consistent with the values derived by Ro...

Proof. One direction is easy, namely TQBF ∈ PSpace. Once again, to achieve a spaceefficient algorithm, we use recursion. If the leading quantifier is ∃x, then we recursively check the two cases of setting x to 0 and 1, and return true if one of them is true. Similarly, if the leading quantifier is ∀x, then we recursively check the two cases of setting x to 0 and 1, and return true if both of th...

We consider a system of two coupled queues, Q1 and Q2. When both queues are backlogged, they are each served at unit rate. However, when one queue empties, the service rate at the other queue increases. Thus, the two queues are coupled through the mechanism for dynamically sharing surplus service capacity. We derive the asymptotic workload behavior at Q1 for various scenarios where at least one...
