Background Each year, five million people are left disabled after stroke. Upper -extremity (UE) dysfunction is a leading problem. Neuroplasticity can be enhanced by non-invasive brain stimulation (NIBS) but evidence from large, randomized multicenter trial ...

Wireless, miniaturised and distributed neural interfaces are emerging neurotechnologies. Although extensive research efforts contribute to their technological advancement, the need for real-time systems enabling simultaneous wireless information and power ...

The Gm/ID approach has proven to be an efficient technique for the design of low-power analog circuits even in advanced technology nodes. It has already been shown that the normalized Gm/ID is actually a universal figure-of-merit (FoM) that is independent ...

We present a cryogenic system design and development for ice lithography. The cryo-stage is designed with embedded channels to allow direct liquid nitrogen flow, enabling fast cryogenic cooling, and low sample temperature. The stage cools down to 78.8 K in ...

Unstructured neural network pruning algorithms have achieved impressive compression ratios. However, the resulting-typically irregular-sparse matrices hamper efficient hardware implementations, leading to additional memory usage and complex control logic t ...

Capacitive micromachined ultrasonic transducers (CMUTs) are regarded as an attractive candidate in bio-applications such as imaging and molecule monitoring. However, the previous researches on biochemical sensing are mostly air-coupled application based on ...

A needle-shaped electrochemical sensor based on platinum electrodes is proposed in this paper. These platinum electrodes provide improved mechanical properties with respect to previous prototypes proposed in literature. This makes them suitable for inserti ...

RILEM TC 267 TRM- "Tests for Reactivity of Supplementary Cementitious Materials" recommends the Rapid Reliable Relevant (R-3) test as a method for determining the chemical reactivity of supplementary cementitious materials (SCMs) in Portland cement blends. ...

In this paper we present a technique to broaden the beamwidth of conventional patch microstrip antennas by using parasitic elements. This technique allows to keep the main advantages of microstrip antennas while increasing their beamwidth. We provide guide ...

Objective. Motor neuroprostheses require the identification of stimulation protocols that effectively produce desired movements. Manual search for these protocols can be very time-consuming and often leads to suboptimal solutions, as several stimulation pa ...

In this work, a Tri-Gate AlGaN/GaN metal-oxide-semiconductor high electron mobility transistor (MOSHEMT) with lithium nickel oxide (LiNiO) gate dielectric is demonstrated for enhancement-mode (e-mode) operation. The high-quality of pulse-laser-deposited (P ...

The introduction of modular design in total hip arthroplasty has enabled the use of different materials in one single configuration and the adjustment of the prosthesis to the patient's body, and facilitated medical revisions. However, modularity leads to ...

Dielectric elastomer actuators (DEAs) have extremely advantageous characteristics such as lightness, compactness, flexibility, and large displacements. However, in order to operate, they can require voltages in the order of several thousands of volts. Thus ...

In this work, we report a novel Indium Arsenide-on-insulator (InAsOI) FinFET platform designed with record high aspect ratio that favors the use of the devices as charge sensors. InAs has very high mobility among III-V semiconductors and an intrinsic surfa ...

This brief reports the analytical modeling and measurements of the inflection in the MOSFET transfer characteristics at cryogenic temperatures. Inflection is the inward bending of the drain current versus gate voltage, which reduces the current in weak and ...

Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...

The development of novel strategies to augment motor training success is of great interest for healthy persons and neurological patients. A promising approach is the combination of training with transcranial electric stimulation. However, limited reproduci ...

Building a large-scale quantum computer requires the co-optimization of both the quantum bits (qubits) and their control electronics. By operating the CMOS control circuits at cryogenic temperatures (cryo-CMOS), and hence in close proximity to the cryogeni ...

This This article discusses the design of a current controller for a converter system connected to the electrical grid through a LCL filter. A form of compensation is proposed and implemented to mitigate the effects of the computational delay in the discre ...
