<div>In this paper, we present an integrated and fire neuron designed in a 22-nm FDSOI technology. In this novel design, we deploy the back-gate terminal of FDSOI technology for a tunable design. For the first time, we show analytically and with pre- and post-layout simulations a neuron with tunable spiking frequency using the back-gate voltage of FDSOI technology. The neuron circuit is designed in the sub- hreshold region and dissipates an ultra-low energy per spike of the order of Femto Joules per spike. With the layout area of only 30 um2, this is the smallest neuron circuit reported to date.</div>

Inspired by the astonishing ability of the fish, more and more researchers devote themselves to improving the performance of the underwater robotic propeller. In this paper, a novel design and a preliminary performance study of a lightweight robofish are presented. Firstly, the principle of the actuator by magnetomotive force is introduced. Secondly, the implementation of the biomimetic robofish is investigated. Finally, several expriments are conducted to explore the energy consumption of the magnetomoive force actuator and the affection of the kinematic parameters on the velocity. The experimental results reveal that the novel biomimetic robofish driven by magnetomotive force has a low energy consumption and shows good performance in swimming.

In this paper, we report nanowire drain saturation current sensitivity property to measure femtomol level change in drain current due to different proteins i.e. DNA with numerical simulation and fabricated polysilicon nanowire based on the theoretical predictions. In addition, the drain current will also be affected by the back-gate voltage and will increase as the back-gate voltage increases. A 3-dimensional Synopsis tool is used to investigate the drain current behavior for a polysilicon nanowire. The scattering compact model reported result of detailed numerical calculation shows in good agreement, indicating the usefulness of scattering compact model. Whereas 3D synopsis unable to explain the whole region of the drain current characteristics in linear region which uses quantum mechanics model approach.

The Road

Spin Waves (SWs) propagate through magnetic waveguides and interfere with each other without consuming noticeable energy, which opens the road to new ultra-low energy circuit designs. In this paper we build upon SW features and propose a novel energy efficient Full Adder (FA) design consisting of The FA 1 Majority and 2 XOR gates, which outputs Sum and Carry-out are generated by means of threshold and phase detection, respectively. We validate our proposal by means of MuMax3 micromagnetic simulations and we evaluate and compare its performance with state-of-the-art SW, 22nm CMOS, Magnetic Tunnel Junction (MTJ), Spin Hall Effect (SHE), Domain Wall Motion (DWM), and Spin-CMOS implementations. Our evaluation indicates that the proposed SW FA consumes 22.5% and 43% less energy than the direct SW gate based and 22nm CMOS counterparts, respectively. Moreover it exhibits a more than 3 orders of magnitude smaller energy consumption when compared with state-of-the-art MTJ, SHE, DWM, and Spin-CMOS based FAs, and outperforms its contenders in terms of area by requiring at least 22% less chip real-estate.

First Time

To calculate the optimal parameters of outbuildings, a mathematical model and method for optimizing the shape and resistance of heat transfer for opaque and transparent structures with a certain constant number of faces, building volume and amount of insulation to minimize the thermal balance of enclosing structures with the environment during the heating period In the course of calculations the geometrical parameters of translucent, opaque structures in the heat-insulating shell of buildings are determined taking into account heat losses, heat influx from solar radiation by the criterion of ensuring minimum heat losses through enclosing structures, rational parameters (buildings) The given technique and mathematical models should be used in the future in the design of energy efficient buildings in the reconstruction and thermal modernization of buildings. This will increase their energy efficiency and, accordingly, the energy efficiency class of buildings. For the research faceted attached building in the form of a triangular pyramid, the reduction in heat loss was 14.82 percent only due to the optimization of the shape and redistribution of the insulation. Similar results were obtained for other initial forms. For the first time, a computerized method was proposed, an algorithm and application package Optimparam for multiparameter shape optimization and insulation of translucent and opaque structures for outbuildings with a given number of arbitrarily arranged faces were developed.

We report the detection of pulsed gamma-ray emission from the Geminga pulsar (PSR J0633+1746) between 15 GeV and 75 GeV. This is the first time a middle-aged pulsar has been detected up to these energies. Observations were carried out with the MAGIC telescopes between 2017 and 2019 using the low-energy threshold Sum-Trigger-II system. After quality selection cuts, ∼80 h of observational data were used for this analysis. To compare with the emission at lower energies below the sensitivity range of MAGIC, 11 years of Fermi-LAT data above 100 MeV were also analysed. From the two pulses per rotation seen by Fermi-LAT, only the second one, P2, is detected in the MAGIC energy range, with a significance of 6.3σ. The spectrum measured by MAGIC is well-represented by a simple power law of spectral index Γ = 5.62 ± 0.54, which smoothly extends the Fermi-LAT spectrum. A joint fit to MAGIC and Fermi-LAT data rules out the existence of a sub-exponential cut-off in the combined energy range at the 3.6σ significance level. The power-law tail emission detected by MAGIC is interpreted as the transition from curvature radiation to Inverse Compton Scattering of particles accelerated in the northern outer gap.

First Time

Did Alex Arnold kill Betty Gail Brown? I have been asked that question hundreds of times and have never found it easy to answer. My difficulty with the question began almost as soon as I saw Arnold for the first time, in a jail cell in Lexington two or three days after he had confessed to the killing and been charged with murder. Although Arnold was not at the time hallucinating about mind-reading machines or talking to creatures on the walls of his jail cell, he was quite obviously still suffering mental impairments. He had lost his access to alcohol a little more than a week earlier and had been sitting alone in jail for most of that period; he seemed to have passed through the worst of his withdrawal symptoms, but was not even close to a total escape from the consequences of at least ten years of drunkenness. He had lost the “good feelings” he gained from drinking (elevated mood, self-confidence, and nonexistent inhibitions) and had found in their place high anxiety, low energy, some disorientation, and a crystal-clear desire to be left alone. It was under these conditions, speaking very softly and seeming almost to be talking to himself, that he said, “I killed her.” Had he made this statement under normal circumstances, in a clean and clear state of mind, it would have been easy to believe that the state had found the killer of Betty Gail Brown. But the circumstances under which the statement was made were far from normal, although they were much closer to normal that those that prevailed a few days earlier when he signed the confession that led to his prosecution for murder....
