A sample-and-hold amplifier designed for the front end of high-speed low-power analog-to-digital converters employs a BiCMOS sampling switch and a low-voltage amplifier to achieve a sampling rate of 200 MHz while allowing input/output voltage swings of 1.5 V with a 3-V supply. The circuit also incorporates a cancellation technique to relax the trade-off between the holdmode feedthrough and the ...

Bulow and Levin’s (2006) “Matching and Price Competition” studies a matching model in which hospitals compete for interns by offering wages. We relax the assumption of symmetric linear costs and compare the pricing equilibrium that results to the firm-optimal competitive equilibrium. With linear and asymmetric costs, competition in the pricing equilibrium may not be localized, but all other qua...

We study the parametric perturbation of Markov chains with denumerable state spaces. We consider both regular and singular perturbations. By the latter wemean that transition probabilities of aMarkov chain, with several ergodic classes, are perturbed such that (rare) transitions among the different ergodic classes of the unperturbed chain are allowed. Singularly perturbed Markov chains have bee...

Strengthening a result of Yuen-Kennedy-Lax and Holevo (YKLH), we relax the (redundant) standard conditions for optimality of minimum-error quantum measurements while retaining sufficiency. This result is made robust by giving quantitative bounds on non-optimality when the simplified conditions fail to hold. These conditions serendipitously appeared as an intermediate step in Barnett and Croke’s...

Analogy completion has been a popular task in recent years for evaluating the semantic properties of word embeddings, but the standard methodology makes a number of assumptions about analogies that do not always hold, either in recent benchmark datasets or when expanding into other domains. Through an analysis of analogies in the biomedical domain, we identify three assumptions: that of a Singl...

BACKGROUND The Relaxin for the Treatment of Acute Heart Failure (RELAX-AHF) trial enrolled 1161 patients admitted to the hospital for acute heart failure (AHF) to evaluate the therapeutic efficacy of serelaxin, a recombinant form of human relaxin-2. We characterized how representative RELAX-AHF clinical trial enrollees were to those patients with AHF found in international registries. METHODS...

Mutual localization provides a consensus of reference frame as an essential basis for cooperation in multi-robot systems. Previous works have developed certifiable and robust solvers relative transformation estimation between each pair robots. However, recovering poses robotic swarm with partially mutual observations is still unexploited problem. In this letter, we present complete algorithm it...

We derive scaling relations based on freefall and isotropy assumptions for the kinematic small-scale dynamo growth rate amplification factor over course of mixing, saturation, decay phases Rayleigh–Taylor instability (RTI) in a fully ionized plasma. The are tested using sets three-dimensional, visco-resistive MHD simulations RTI. They found to hold saturation phase, but exhibit discrepancies du...
