The QCD effective charge αg1(Q) is an observable that characterizes the magnitude of strong interaction. At high momentum Q, it coincides with running coupling αs(Q). low offers a nonperturbative definition coupling. We have extracted from measurements carried out at Jefferson Lab span very to moderately Q domain, 0.14≤Q≤2.18 GeV. precision new results much improved over previous extractions an...

Solution: By the adjunction formula, the canonical divisor class is KC = OC(d− 3), that is, plane curves of degree d− 3 cut out canonical divisors on C. It follows that if d ≥ 4 then any two points p, q ∈ C impose independent conditions on the canonical series |KC |; that is, h(KC(−p − q)) = g − 2, so by Riemann-Roch h(OC(p+ q)) = 1, i.e., C is not hyperelliptic. Similarly, if d ≥ 5 then any th...

This study evaluated the clinical impact of Q-wave presence on ECG at presentation of patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).From April 2005 to September 2009, 184 consecutive STEMI patients who underwent primary PCI within 12 hours of chest pain onset were retrospectively evaluated. Patients were grouped acco...

A 1.1-GHz fully integrated GaAs MESFET active inductor is presented in this paper. Both the inductance and loss resistance are tunable with the inductance independent of series loss tuning. The measured loss resistance is tunable over a 10to +15range with a corresponding change in inductance of less than 10% at 100 MHz and less than 4% for frequencies above 500 MHz. The inductance is tunable fr...

A matrix is free, or generic, if its nonzero entries are algebraically independent. Necessary and sufficient combinatorial conditions are presented for a complex free matrix to have a free Moore-Penrose inverse. These conditions extend previously known results for square, nonsingular free matrices. The result used to prove this characterization relates the combinatorial structure of a free matr...

We study multiple ionization in proton collisions with water, methane, and ammonia molecules using an independent-atom model. Previous work on total (net) capture cross sections is extended to treat the multiple-ionization channels explicitly. present theoretical framework charge-state correlated processes within independent-atom-model approach, which uses geometric screening introduced for dif...

Words of fixed size q are commonly referred to as q-grams. We consider the problem of q-gram filtration, a method commonly used to speed up sequence comparison. We are interested in the statistics of the number of q-grams common to two random texts (where multiplicities are not counted) in the non uniform Bernoulli model. In the exact and dependent model, when omitting border effects, a q-gram ...
