Application-specific ICs have been traditionally used to support the high computational and data rate requirements in medical ultrasound systems, particularly receive beamforming. Utilizing previously developed efficient front-end algorithms, this paper, we present a simple programmable computing architecture, consisting of field-programmable gate array (FPGA) digital signal processor (DSP), core processing. It was found that 97.3% 51.8% FPGA DSP resources are, respectively, needed all...
We propose Accel-Brake Control (ABC), a simple and deployable explicit congestion control protocol for network paths with time-varying wireless links. ABC routers mark each packet an "accelerate" or "brake", which causes senders to slightly increase decrease their windows. Routers use this feedback quickly guide towards desired target rate. requires no changes header formats user devices, but achieves better performance than XCP. is also incrementally deployable; it operates correctly when...
A major impediment to the adoption of vehicular ad-hoc networks (VANETs) today is their privacy and security concerns. In this paper, we address aspects VANETs. Specifically build a scheme that provides non-repudiation, message authentication, integrity, non-traceability (or source location privacy) while maintaining low overhead in communication support requirements for beaconing mechanism. Our leverages fact an endpoint only requires knowledge velocity another not its identity, thereby our...
Renewable energy is becoming an important power source for data centers, especially with the zero-carbon waste pledges made by big cloud providers. However, one of main challenges renewable sources high variability produced. Traditional approaches such as batteries or transmitting to grid fall short on scale, overhead, "green-ness". We propose Virtual Battery: instead adapting availability match computation demand we shift computational meet power. requiring applications either be flexible...
In this paper, we present a new demodulation method to reduce hardware complexity in phase-rotation-based beamforming. Due its low sensitivity phase delay errors, quadrature demodulation, which consists of mixing and lowpass filtering, is commonly used ultrasound machines. However, because it requires two filters for each channel remove harmonics after mixing, the direct use computationally expensive. To alleviate high computational requirement have developed two-stage technique dynamic...
Thrombocytopenia is a common feature of babesiosis.The mechanism for thrombocytopenia in babesiosis remains elusive.We report case with severe new onset immune (ITP).In addition to antibiotics treatment babesiosis, ITP therapy was administered.ITP the present most likely triggered by babesia infection.The severity this not proportional parasitemia.The neoantigen triggering autoimmune response requires further characterization.

Heuristics are ubiquitous in computer systems. Examples include congestion control, adaptive bit rate streaming, scheduling, load balancing, and caching. In some domains, theoretical proofs have provided clarity on the conditions where a heuristic is guaranteed to work well. This has not been possible all domains because proving such guarantees can involve combinatorial reasoning making it hard, cumbersome error-prone. this paper we argue that computers should help humans with part of...
