Rotational cryptanalysis is a statistical method for attacking ARX constructions. It was previously shown that ARX-C, i.e., ARX with the injection of constants can be used to implement any function. In this paper we investigate how rotational cryptanalysis is affected when constants are injected into the state. We introduce the notion of an RX-difference, generalizing the idea of a rotational d...

We compared the duration of the protective effect of two beta-adrenoceptor agonists, fenoterol (200 micrograms) and salbutamol (200 micrograms), the anticholinergic agent ipratropium (80 micrograms), and the combination of fenoterol (200 micrograms) and ipratropium (80 micrograms) against challenge by eucapnic voluntary hyperventilation (EVH). Twelve patients with asthma performed EVH for two o...

We seek critical points of the functional E(u) = j |Vw|, where Ω is Ω the unit disk in (R and u: Ω -+ S satisfies the boundary condition u = y on dΩ. We prove that if y is not a constant, then E has a local minimum which is different from the absolute minimum. We discuss in more details the case where y(x, y) = (Rx, Ry, ̂ Γ^R) and R <

UNLABELLED The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element. Here, we applied pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing to reconstruct the evolutionary history of the ST131 clone. PFGE-ba...

Wireless power transfer (WPT) has been studied formore than one hundred years sinceNikola Tesla proposed his WPT concept. Asmore and more portable electronic devices and consumer electronics are developed and used, the need for WPT technology will continue to grow. Recently, WPT via strongly coupled magnetic resonances in the near field has been reported by Kurs et al. (2007). The basic princip...

BACKGROUND Suboptimal prescribing and medications use is a problem for health systems globally. Systematic reviews are a comprehensive resource that can help guide evidence-informed decision-making and implementation of interventions addressing such issues; however, a barrier to the use of systematic reviews is their inaccessibility (due to both dispersion across journals and inaccessibility of...

Direct Interface Circuits (DICs) are simple circuits used in readouts for all types of sensors. For resistive sensors, DICs perform a resistance-to-time-to-digital conversion using just the sensor, some calibration resistors, one or two capacitors, and Digital Processor. These require variable number charging discharging cycles capacitor to estimate sensor resistance, Rx, increasing both acquis...

A constructive framework of recent work in the semantics of programming languages is offered. The criticism is directed not so much at the techniques and results obtained as at the use to which they are put. The fact that denotational (or “mathematical”) semantics plays on the whole a passive (“descriptive”) rôle, while operational semantics plays on the whole an active (“prescriptive”) rôle, i...
