SAN DIEGO – The use of antimicrobial soap and ointment on all patients admitted to intensive care units led to a 37% reduction in methicillin-resistant Staphylococcus aureus clinical isolates and a 44% reduction in bloodstream infections caused by all pathogens, results from a large multicenter study demonstrated. “While earlier, smaller studies have suggested benefit from bathing with antibact...

In this paper, we propose a simple method for modifying Walsh-Hadamard spreading sequences to improve their correlation properties for asynchronous DS CDMA applications, while maintaining their orthogonality for perfect synchronization. Simulation results for the DS CDMA systems utilizing 32-chip modified WalshHadamard sequences and are presented and compared to those achieved in the case of sy...

Size-based droplet sorting can be used to improve the monodispersity of droplet populations in chemical assays, and as a label-free measurement in cell-in-droplet assays. Several microfluidic approaches can efficiently perform binary sorting based on a size threshold; however, the thresholds are typically fixed by the channel design. This paper presents a passive drop sorting technique in which...

The paper presents an improved tuning method implemented for a differential active inductor based RF bandpass filter. Derived from a previous designed transistor-only second order filter topology, independent frequency and quality factor tuning are demonstrated in 0.18 μm CMOS technology. The circuit has been basically designed for a maximum frequency of 2.4 GHz, high enough to cover the main w...

The application specific paper describes a high precision, wide speed rotation sensing approach based on the Universal Frequency-to-Digital Converter (UFDC-1). Such design approach lets significantly simplify the design process, reduce time-to-market and production price and produce tachometers and tachometric systems with high metrological performances and digital self-adaptive smart rotation ...

The use of switched capacitors as wide-range, programmable resistive elements in spatially extensive artificial dendritic trees (ADT's) is described. We show that silicon neuro-morphs with ADT's can produce impulse responses that last millions of times longer than the initiating impulse and that dynamical responses are tunable in both shape and duration over a wide range. The switched-capacitor...

An improved method for estimating the frequency of a single complex sinusoid in complex additive white Gaussian noise is proposed. The method uses a modified version of the weighted linear predictor to achieve optimal accuracy at low/moderate SNR while retaining its speed and wide acquisition range. Consequently, it has an advantage over known methods that use the weighted phase averager since ...

  Abstract   Background: Parosteal osteosarcoma is rare low-grade malignancy which arises   on the surface of the metaphysis of long bones it has a low propensity to metastasize.   Different surgical treatment options including marginal resection, wide resection   and amputation were recommended for the tumor. The purpose of the study was to   assess the results of different surgical treatment ...

An electrometer using complementary metal–oxide–semiconductor bilateral switches for automatic range control is described. Based on a dual-switching configuration, the electrometer is capable of current measurement over eight orders of magnitude. Together with a voltage shifter, this circuit provides a quasilinear analog output for the measurement of input dc current between 10 and 10 A. The ap...

We consider the problem of minimizing regret with respect to a given set S of pairs of time selection functions and modifications rules. We give an online algorithm that has O( √ T log |S|) regret with respect to S when the algorithm is run for T time steps and there are N actions allowed. This improves the upper bound of O( √ TN log(|I||F|)) given by Blum and Mansour [BM07a] for the case when ...
