This paper investigates public key cryptosystems (PKC) in the rank metric and term-rank metric. For security analysis of cryptosystems, we introduce a GPT system. Recently, respective structural attacks this system were proposed by Over-beck. For GPT system, Overbeck's attack succeeds in polynomial time. We will discuss the new construction of Shiki system. This paper describes Overbeck's attack to the new Shiki system. Also, investigation of the possibility of using term-rank codes in public key cryptosystems.

This paper demonstrates the importance of interdisciplinary collaboration between teams of medical researchers, product design researchers, and computerscience students. Their combined work resulted in both a concept and a product, a Smart Health Assistive Bag for children being hospitalized. The Child Psychiatry Inpatient Unit at Sheba Medical Center provides mental health services to children suffering from a variety of psychopathological conditions. The multidisciplinary staff takes a family-oriented approach where parents and caregivers are encouraged to be active participants in the treatment team throughout their child's stay. Our work focused on the design and development of a Smart Bag, which supports this family-oriented approach, encourages the involvement of the family during the child's stay and collects new data for future functional analysis. Engineering and design students from both Shenkar and the Technion worked with Sheba's clinicians to create a conceptual prototype that advances the defined theoretical needs and build a working prototype. Our Smart Bag aimed at aiding child hospitalizations in the Psychiatrist Inpatient Unit is an important innovative tool for Sheba's Smart Health facility. It is designed to help the child in adjusting to the unit and be an active participant in their daily routine while in the unit. Additionally, because it has IoT sensors and is linked to a network through a digital platform, it supports the child's family and caregivers in staying updated regarding the child's progress. The Smart Bag can apprise the family about the child's daily achievements by informing them of tokens given to the child for desirable behavior. It updates both family and caregivers regarding the current stage in the child's treatment. Such on-going communication involving the child, caregivers and clinicians reduces the stress and worry that families often feel when their child is hospitalized in the Psychiatrist Unit and improves the therap

Background: Lower production of H2O2 in water is a hallmark of ultra-high dose rate (UHDR) compared to the conventional dose rate (CDR). However, the current computational models based on the predicted yield of H2O2 are the opposite of the experimental data. Purpose: To present a multi-scale formalism to reconcile the theoretical modeling and the experimental observations of H2O2 production and provide a mechanism for the suppression of H2O2 at FLASH-UHDR. Methods: We construct an analytical model for the rate equation in the production of H2O2 from ·OH-radicals and use it as a guide to propose a hypothetical geometrical inhomogeneity in the configuration of particles in the UHDR beams. We perform a series of Monte Carlo (MC) simulations of the track structures for a system of charged particles impinging the medium in the form of clusters and/or bunches. Results: We demonstrate the interplay of diffusion, reaction rates, and overlaps in track-spacing attribute to a lower yield of H2O2 at UHDR vs. CDR. This trend is reversed if spacing among the tracks becomes larger than a critical value, with a length scale that is proportional to the diffusion length of ·OH-radicals modulated by a rate of decay due to recombination with other species, available within a track, and the space among the tracks. The latter is substantial on the suppressing of the H2O2 population at UHDR relative to CDR. Under these conditions in our MC setup, the reduction of H2O2 dose rate effect within 1ms time-scale is attributed mainly to several orders of magnitude earlier times, e.g., 1 ns of the e−aq reaction with ·OH-radicals and negligible reaction with ·H. Conclusions: Based on our analysis of the present work, at UHDR, the lower yield in H2O2 can be interpreted as a signature of bunching the particles in beams of ionizing radiation, and temporal correlations and time-dependent chain of reactions. The beams enter the medium in closely packed clusters and form inhomogeneities in the track-str

The research paper presents a novel analysis of textual data based on Natural Language Processing (NLP) techniques to analyse New York Times articles from January 2019 to May 2023. The purpose of this paper is to gain an understanding of the economic impact that follows Covid-19 disease. New York Times (NYT), it was started in 1884 is one of the most prominent newspapers in the world. Additionally, we have used the New York Times Archive API to collect the data for the given timeframe. By analysing sentiment analysis, topic modelling, entity recognition, and keyword extraction, valuable insights can be gathered into market trends, industry shifts, and policy interventions. The authors have created a data science pipeline using Amazon Web Services (AWS), which enables data collection, storage, and visualization. It contributes to a better understanding of the pandemic's short-term and long-term economic effects. The results of this study demonstrate Natural Language Processing techniques' potential as a tool for financial analytics, assisting policymakers, economists, and businesses in formulating recovery strategies.

In multivalley systems, the valley pseudospin offers rich physics going from encoding of information by its polarization (valleytronics), to exploring novel phases of matter when its degeneracy is changed. Here, by strain engineering, we reveal fully valley-polarized quantum Hall phases in the Pb1−xSnxSe Dirac system. Remarkably, when the valley energy splitting exceeds the fundamental band gap, we observe a “bipolar quantum Hall phase,” heralded by the coexistence of hole and electron chiral edge states at distinct valleys in the same quantum well. This suggests that spatially overlaid counterpropagating chiral edge states emerging at different valleys do not interfere with each other.
