The main goal of this paper is to provide asymptotic expansions for the numbers #{p 6 x : p prime, sq(p) = k} for k close to ((q − 1)/2) logq x, where sq(n) denotes the q-ary sum-of-digits function. The proof is based on a thorough analysis of exponential sums of the form ∑ p6x e(αsq(p)) (the sum is restricted to p prime), where we have to extend a recent result by the second two authors.

4-Demethoxydaunorubicin (4-DMDR), an anthracycline ana logue available in i.v. and p.o. form, has shown significant antitumor activity in murine tumor models while producing less cardiac toxicity than doxorubicin at equimyelotoxic doses. Phase I and clinical pharmacology studies of the i.v. and p.o. preparation were performed. With i.v. 4-DMDR, consistent myelosuppression was observed at a dose...

The airline industry faces economic challenges making it paramount that they provide satisfactory service to customers relative to their expectations. This study uses a service quality-adjusted data envelopment analysis (SQ-adjusted DEA) to study US-based airline carrier operational efficiency. We found that airlines can overcome the traditional tradeoff between quality and productivity. Using ...

BACKGROUND Sleep disturbance is a common complaint in major depressive disorder (MDD) including impairment of both subjective and objective parameters. All antidepressants affect sleep architecture and quality. AIM This trial was designed to compare the effects of short-term use of citalopram with fluoxetine on sleep quality (SQ) of patients with MDD based on Diagnostic and Statistical Manual...

Polychlorinated biphenyls (PCBs) exert a broad range of toxicity via both parent compounds and their metabolites. Our previous study showed that hydroquinone (H2Q) metabolites of PCBs act as cosubstrates for prostaglandin H synthase (PGHS), and are oxidized by this enzyme to corresponding quinones (Q). The goal of this thesis is to illuminate the PGHS-mediated toxicity of lower chlorinated PCBs...

Previous research has developed evaluation measurement for electronic service quality (e-SQ) but has ignored the interdependence perspective of the criteria and sub-criteria for e-SQ evaluation. Therefore, this study aims to propose a hybrid analytic network process (ANP) model as an improved method to evaluate multiple-criteria and sub-criteria of e-SQ with the interdependence perspective. Thi...

Abstract We consider a system of qubits affected by an environmental random-telegraph process (RTP) noise and investigate the recently proposed idea using spectator qubit (SQ) as probe to remove effects from data (DQ). By measuring SQ at various times with particular measurement bases, their readouts can be used extract information effects. In this work, we propose use recurrent neural network ...
