North Korean leader Kim Jong Un observed the successful test of an unspecified “newly developed ultramodern tactical weapon,” state media reported Friday, in an apparent bid to apply pressure on the United States and South Korea.

I noticed some very interesting news last week, widely reported in the technical press, and you can find the source press release here. In a nutshell, the Embedded Microprocessor Benchmark Consortium (EEMBC) has formed a group to look at benchmarks for ultra low power microcontrollers. Initially chaired by Horst Diewald, chief architect of MSP430^TM microcontrollers at Texas Instruments, the group's line-up is an impressive "who's who" of the microcontroller space, including Analog Devices, ARM, Atmel, Cypress, Energy Micro, Freescale, Fujitsu, Microchip, Renesas, Silicon Labs, STMicro, and TI.

As the press release explains, unlike usual processor benchmark suites which focus on performance, the ULP benchmark will focus on measuring the energy consumed by microcontrollers running various computational workloads over an extended time period. The benchmarking methodology will allow the microcontrollers to enter into their idle or sleep modes during the majority of time when they are not executing code, thereby simulating a real-world environment where products must support battery life measured in months, years, and even decades.

Processor performance benchmarks seem to be as widely criticized as EPA fuel consumption figures for cars - and the criticism is somewhat related. There is a suspicion that manufacturers can tune the performance for better test results, rather than better real-world performance. On the face of it, the task to produce meaningful ultra low power benchmarks seems even more fraught with difficulties. For a start, there is a vast range of possible energy profiles - different ways that computing is spread over time - and a plethora of low power design techniques available to optimize the system for the set of profiles that particular embedded system is likely to experience. Furthermore, you could argue that, compared with performance in a computer system, energy consumption in an ultra low power embedded system has less to do with the controller itself and more to do with other parts of the system like the memories and mixed-signal real-world interfaces.

EEMBC cites that common methods to gauge energy efficiency are lacking in growth applications such as portable medical devices, security systems, building automation, smart metering, and also applications using energy harvesting devices. At Cadence, we are seeing huge growth in these areas which, along with intelligence being introduced into all kinds of previously "dumb" appliances, is becoming known as the "Internet of Things." Despite the difficulties, with which the parties involved are all deeply familiar, I applaud this initiative. While it may be difficult to get to apples-to-apples comparisons for energy consumption in these applications, most of the time today we don't even know where the grocery store is. If the EEMBC effort at least gets us to the produce department, we're going to be better off.

Hello,

I am using ultrasim Version 18.1.0.314.isr5  64bit 03/26/2019 06:33 (csvcm20c-2).

When I run my netlist, ultrasim is blocked in the first DC stage and takes forever. Then it will fail or never progress. I am using a 22nm BSIMBULK model. I tried to tune different accuracy and convergence aids options but noting works.

 When I run the same netlist with spectre it works fine with no problem.

Also, If I use another model (not BULKSIM), ultrasim will work and converge with no problem.

My first feeling is that ultrasim has a problem with using BSIMBULK model.

Could you please advice,

Thank you,

Kotb

ABSTRACT

In Escherichia coli, the chemotaxis response regulator CheY-P binds to FliM, a component of the switch complex at the base of the bacterial flagellar motor, to modulate the direction of motor rotation. The bacterial flagellar motor is ultrasensitive to the concentration of unbound CheY-P in the cytoplasm. CheY-P binds to FliM molecules both in the cytoplasm and on the motor. As the concentration of FliM unavoidably varies from cell to cell, leading to a variation of unbound CheY-P concentration in the cytoplasm, this raises the question whether the flagellar motor is robust against this variation, that is, whether the rotational bias of the motor is more or less constant as the concentration of FliM varies. Here, we showed that the motor is robust against variations of the concentration of FliM. We identified adaptive remodeling of the motor as the mechanism for this robustness. As the level of FliM molecules changes, resulting in different amounts of the unbound CheY-P molecules, the motor adaptively changes the composition of its switch complex to compensate for this effect.

IMPORTANCE The bacterial flagellar motor is an ultrasensitive motor. Its output, the probability of the motor turning clockwise, depends sensitively on the occupancy of the protein FliM (a component on the switch complex of the motor) by the input CheY-P molecules. With a limited cellular pool of CheY-P molecules, cell-to-cell variation of the FliM level would lead to large unwanted variation of the motor output if not compensated. Here, we showed that the motor output is robust against the variation of FliM level and identified the adaptive remodeling of the motor switch complex as the mechanism for this robustness.

Microscopy and rapid diagnostic tests (RDTs) are the main diagnostic tools for malaria but fail to detect low-density parasitemias that are important for maintaining malaria transmission. To complement existing diagnostic methods, an isothermal reverse transcription-recombinase polymerase amplification and lateral flow assay (RT-RPA) was developed. We compared the performance with that of ultrasensitive reverse transcription-quantitative PCR (uRT-qPCR) using nucleic acid extracts from blood samples (n = 114) obtained after standardized controlled human malaria infection (CHMI) with Plasmodium falciparum sporozoites. As a preliminary investigation, we also sampled asymptomatic individuals (n = 28) in an area of malaria endemicity (Lambaréné, Gabon) to validate RT-RPA and assess its performance with unprocessed blood samples (dbRT-RPA). In 114 samples analyzed from CHMI trials, the positive percent agreement to uRT-qPCR was 90% (95% confidence interval [CI], 80 to 96). The negative percent agreement was 100% (95% CI, 92 to 100). The lower limit of detection was 64 parasites/ml. In Gabon, RT-RPA was 100% accurate with asymptomatic volunteers (n = 28), while simplified dbRT-RPA showed 89% accuracy. In a subgroup analysis, RT-RPA detected 9/10 RT-qPCR-positive samples, while loop-mediated isothermal amplification (LAMP) detected 2/10. RT-RPA is a reliable diagnostic test for asymptomatic low-density infections. It is particularly useful in settings where uRT-qPCR is difficult to implement.

Physician-led thoracic ultrasound (TUS) has substantially changed how respiratory disorders, and in particular pleural diseases, are managed. The use of TUS as a point-of-care test enables the respiratory physician to quickly and accurately diagnose pleural pathology and ensure safe access to the pleural space during thoracentesis or chest drain insertion. Competence in performing TUS is now an obligatory part of respiratory speciality training programmes in different parts of the world. Pleural physicians with higher levels of competence routinely use TUS during the planning and execution of more sophisticated diagnostic and therapeutic interventions, such as core needle pleural biopsies, image-guided drain insertion and medical thoracoscopy. Current research is gauging the potential of TUS in predicting the outcome of different pleural interventions and how it can aid in tailoring the optimum treatment according to different TUS-based parameters.

Purpose:

Human B7-H3 (hB7-H3) is a promising molecular imaging target differentially expressed on the neovasculature of breast cancer and has been validated for preclinical ultrasound (US) imaging with anti–B7-H3-antibody-functionalized microbubbles (MB). However, smaller ligands such as affibodies (ABY) are more suitable for the design of clinical-grade targeted MB.

BACKGROUND AND PURPOSE:

It is not known how radiomics using ultrasound images contribute to the detection of BRAF mutation. This study aimed to evaluate whether a radiomics study of gray-scale ultrasound can predict the presence or absence of B-Raf proto-oncogene, serine/threonine kinase (BRAF) mutation in papillary thyroid cancer.

Thanks to its unique three-dimensional manufacturing capacity, ultrafast laser writing is a prime candidate to meet the growing demand for the miniaturization of photonic circuitry, e.g., for scaling up optical quantum computers capacity. Towards this goal, scientists from Canada discovered a phenomenon related to the material electronic resonance that allows a much greater miniaturization of the laser written devices. Surprisingly, the new phenomenon allows other intriguing applications such as a new concept of invisibility.
