Risk Stratification and Prevention of Sudden Cardiac Death in "Arrhythmic" Mitral Valve Prolapse: A Literature Review
Authors: Трисветова Е.Л. 
Published: November 2023

Пролапс митрального клапана в большинстве случаев протекает доброкачественно, вместе с тем с момента первого описания заболевания известно о развитии аритмий сердца, в том числе жизнеугрожающих, и внезапной сердечной смерти, обусловленных факторами риска и патофизиологическими механизмами заболевания. «Аритмический» фенотип включает пролабирование обеих створок митрального клапана, их удлинение и миксоматоз, изменения на электрокардиограмме в виде инвертированного зубца Т в нижнегрудных отведениях, фиброз папиллярных мышц и нижнебазальной стенки миокарда левого желудочка. За истекшее время появились и обсуждаются новые признаки, характерные для желудочковых аритмий при ПМК (дизъюнкция и скручивание фиброзного кольца, признак Pickelhaube, механическая и электрическая неоднородность миокарда левого желудочка). Ограниченные клинические данные, включающие медикаментозные методы, радиочастотную катетерную аблацию, имплантацию кардиовертера-дефибриллятора и хирургическое лечение митрального клапана, свидетельствуют о потенциальной возможности первичной медицинской профилактики внезапной сердечной смерти.
Mitral valve prolapse in most cases proceeds benignly, however, since the first description of the disease, it has been known about the development of cardiac arrhythmias, including life-threatening ones, and sudden cardiac death due to risk factors and pathophysiological mechanisms of the disease. The "arrhythmic" phenotype includes prolapse of both leaflets of the mitral valve, their lengthening and myxomatosis, changes on the electrocardiogram in the form of an inverted T wave in the lower thoracic leads, fibrosis of the papillary muscles and the lower basal wall of the myocardium of the left ventricle. Since then, new signs that are characteristic of ventricular arrhythmias in MVP (disjunction and curling of the fibrous ring, Pickelhaube sign, mechanical and electrical heterogeneity of the left ventricular myocardium) have been discussed. Limited clinical data, including medical methods, radiofrequency catheter ablation, cardioverter-defibrillator implantation, and mitral valve surgery, suggest the potential for primary and secondary medical prevention of sudden cardiac death.

Authors: Каленчиц Т.И. , Кабак С.Л. , Диденко Н.С. , Мельниченко Ю.М. 
Published: November 2023

У пациентки 64 лет, госпитализированной в пульмонологическое отделение клинической больницы г. Минска с внебольничной двусторонней пневмонией и мерцательной аритмией, при компьютерной томографии органов грудной клетки и брюшной полости с контрастированием были диагностированы тромбоэмболия ветвей легочной артерии и инфаркт селезенки. В стационаре пациентке были назначены статины, антибактериальные и нестероидные противовоспалительные средства, а также ривароксабан – прямой ингибитор фактора Ха в дозе 20 мг в сутки. Через месяц пребывания в стационаре она была выписана с улучшением клинического состояния и результатов лабораторных исследований. Инфаркт селезенки является редким осложнением мерцательной аритмии. Клинически бессимптомный инфаркт селезенки можно диагностировать только с помощью компьютерной томографии органов брюшной полости с контрастным усилением. При отсутствии гемодинамических нарушений в малом круге кровообращения компьютерная томография органов грудной клетки с контрастным усилением подтверждает диагноз тромбоэмболии легочной артерии. С целью профилактики висцеральных инфарктов при перманентной форме фибрилляции предсердий необходимо назначить терапевтическую дозу антикоагулянта. Эти препараты стабилизируют уже образовавшиеся тромбы в сосудах большого круга кровообращения и предотвращают появление эмболов в ветвях легочной артерии.
In this report, we present a clinical case of a 64-year-old female patient with permanent atrial fibrillation who was concurrently diagnosed with hemodynamically stable pulmonary thromboembolism and silent splenic infarction at the time of hospitalization. The patient was admitted to the Pulmonary Department with a community-acquired bilateral pneumonia and permanent atrial fibrillation. Chest computed tomography angiography showed direct signs of acute pulmonary thromboembolism. Contrast- enhanced abdominal computed tomography revealed splenic infarction. Statins, antibacterial and non-steroidal anti-inflammatory agents, as well as the direct factor Xa inhibitor (rivaroxaban, 20 mg per day) were prescribed. The patient was discharged 1 month later with improving clinical conditions and laboratory test results. Splenic infarction is an uncommon complication of the permanent atrial fibrillation. Clinically silent splenic infarction can be diagnosed by contrast-enhanced computed tomography. Contrast-enhanced chest computed tomography provides critical information to confirm the diagnosis of pulmonary thromboembolism in the absence of hemodynamic disorders. In order to prevent visceral infarcts due to atrial fibrillation, a therapeutic dose of an anticoagulant must be prescribed. Anticoagulants also allow stabilizing the thrombi and preventing the appearance of embolisms in the lung.

Published: November 2023

The self-service laundry industry has witnessed significant growth and popularity, with self-service laundry franchises emerging as a lucrative investment option. This research investigates the critical success factors (CSFs) and resource scarcity theory that influence the success of self-service laundry franchises in Samut Sakhon, Thailand. The study employs a qualitative approach, conducting in-depth interviews with 25 franchisees operating in the region.
The findings reveal key CSFs that significantly impact franchise success, including strategic location selection, equipment quality and maintenance, competitive pricing, effective marketing strategies, outstanding customer service, and hygiene standards. The franchisor-franchisee relationship, characterized by mutual support, open communication, and shared values, is also found to play a crucial role in franchise performance. Moreover, resource scarcity theory influences franchisee decision-making, providing access to established brands, operational expertise, and technology. Franchisors' resources, such as training, brand recognition, and marketing support, synergistically combine with franchisee resources to enhance overall performance.
Improvement of AlSiO/GaN interface by a novel post deposition annealing using ultra high pressure

Published: November 2023

Abstract
In this study, a novel post-deposition annealing (PDA) technique employing ultra-high pressure was demonstrated for the first time. A 40 nm thick AlSiO gate insulator was deposited using atomic layer deposition (ALD) on n-type gallium nitride (GaN) epitaxial layers grown on free-standing GaN substrates. These PDA techniques were performed at 600 °C in a nitrogen ambient under 400 MPa, with normal pressure conditions used as the references. The annealing duration varied within the range of 10, 30, 60, and 120 min. For normal pressure annealing, the flat-band voltage of capacitance-voltage curves exhibited a shift towards the positive bias direction as the annealing time increased. Conversely, for the 400 MPa annealing, the flat-band voltage approached the ideal curve as the annealing time extended. For 400 MPa and 120 min, low interface state density of ∼5 × 1011 cm−2 eV−1 or less at E
c −0.20 eV was obtained. These results suggest that post-deposition annealing under ultra-high pressure could be a viable method for improving the interfacial characteristics of AlSiO/GaN.
Correction and Addendum for “Consistent Optical and Electrical Noise Figure”
Authors: Noe Reinhold 
Published: November 2023

<p>The minimum noise figure of an electrical amplifier is <em>F</em><sub><em>e</em></sub>=1. E. Desurvire’s traditional optical noise <em>F</em><sub><em>pnf</em></sub> of an optical amplifier has the minimum value <em>F</em><sub><em>pnf</em></sub>=2. If <em>F</em><sub><em>pnf</em></sub> is a noise figure then power, gain and <em>F</em><sub><em>e</em></sub> need to be redefined. <em>F</em><sub><em>pnf</em></sub> is in conflict with physics and <em>F</em><sub><em>e</em></sub>. The correct optical noise figure <em>F</em><sub><em>o</em>,<em>IQ</em></sub>, observable in coherent I&Q receivers, has the minimum <em>F</em><sub><em>o</em>,<em>IQ</em></sub>=1 and is compatible with <em>F</em><sub><em>e</em></sub>. In the derivation of the consistent unified noise figure <em>F</em><sub><em>IQ</em></sub> for all frequencies, from <em>F</em><sub><em>e</em></sub> and <em>F</em><sub><em>o</em>,<em>IQ</em></sub>, thermal noise energy is needed. Its usual simplified expression <em>kT</em> is now replaced by Nyquist’s correct result. This holds also in a unified homodyne noise figure <em>F</em><sub><em>I</em></sub>, against which H. Haus’ unified noise figure <em>F</em><sub><em>fas</em></sub> is discussed. </p>
Personalization of automatic sleep scoring: How best to adapt models to personal domains in wearable EEG
Authors: Lorenzen Kristian , Heremans Elizabeth R. M. , Vos Maarten de , Mikkelsen Kaare B. 
Published: November 2023

<p>Abstract— Wearable EEG enables us to capture large amounts of high-quality sleep data for diagnostic purposes. To make full use of this capacity we need high-performance automatic sleep scoring models. To this end, it has been noted that domain mismatch between recording equipment can be considerable, e.g. PSG to wearable EEG, but a previously observed benefit from personalizing models to individual subjects further indicates a personal domain in sleep EEG. In this work, we have investigated the extent of such a personal domain in wearable EEG, and review supervised and unsupervised approaches to personalization as found in the literature. </p>
<p>We investigated the personalization effect of the unsupervised Adversarial Domain Adaptation and implemented an unsupervised method based on statistics alignment. No beneficial personalization effect was observed using these unsupervised methods. We find that supervised personalization leads to a substantial performance improvement on the target subject ranging from 15% Cohen’s Kappa for subjects with poor performance (κ < 0.70) to roughly 2% on subjects with high performance (κ > 0.80). This improvement was present for models trained on both small and large datasets, indicating that even high-performance models benefit from supervised personalization. We found that this personalization can be beneficially regularized using Kullback-Leibler regularization, leading to lower variance with negligible cost to improvement.</p>
<p>Based on the experiments, we recommend model personalization using Kullback-Leibler regularization.</p>
Blockchains and Taxes: A German Efficiency or Just Another Bureaucratic Wunderkind?
Authors: Bodemer Oliver 
Published: November 2023

<p>In the grand tradition of Sherlock Holmes, the master of deduction, an investigative journey unfolds into the enigmatic world where the steadfast realm of German taxation meets the cryptic and ever-evolving landscape of blockchain technology. Much like the fog-laden streets of Victorian London, the intertwining of these two domains presents a puzzle wrapped in a mystery, shrouded in an enigma. </p>
<p>The tale begins in the orderly corridors of German tax offices, where meticulous records and an unyielding adherence to regulation reign supreme. Into this world of precision and predictability, enters the maverick of modern finance: blockchain. With its promise of decentralization, transparency, and security, blockchain stands at the threshold, poised to revolutionize the very foundations of tax collection and administration. </p>
<p>Yet, as Holmes himself would attest, the introduction of such a disruptive force into a system as established and rigid as the German tax regime is akin to introducing a wild card into a well-ordered deck. The potential for both unparalleled efficiency and unforeseen chaos exists in equal measure. Will blockchain technology prove to be the trusty Watson to Germany’s tax system, a loyal ally in the pursuit of order and justice? Or will it be akin to the elusive Moriarty, a force of disruption and uncertainty? </p>
<p>In this scholarly endeavor, the labyrinth of regulations is traversed, potential harmonies and discords are explored, and deductions are made whether this alliance between blockchain and the German tax system is a match of mutual benefit or a partnership doomed to complexity and contention. </p>
<p>Standing at the crossroads of tradition and innovation, donning the proverbial deerstalker, and arming with the magnifying glass of scrutiny, this intellectual pursuit embarks. For in the words of the illustrious Holmes, "The game is afoot!" </p>

<p>The first thing that comes to everyone’s mind, when we talk about wireless communications is “The Radio”. Starting from the 1800’s till date the radio has undergone several iterations of development. This paper is focused to bring out the three major development stages that are Hardware Defined Radios, Software Defined Radios & Cognitive Radios. With the introduction of cognizance and decision-making algorithms in Cognitive Radios, the scope for incorporation of Artificial Intelligence and Machine Learning has become significant. Intelligent Radios can be considered as the fourth generation of Radio in times to come, which will incorporate Artificial Intelligence and Machine Learning at the core processing unit to improve the overall capability of radio in a congested, constrained and contested electromagnetic spectrum. The Intelligent Radios would be capable of generating hypothesis based on environmental conditions on its own and take intelligent decisions as per the situation reducing the human effort. As the world is moving constantly towards information age, it is clear that future age warfare will be network and electromagnetic spectrum centric. Hence, it is very important for the military to achieve freedom operation in electromagnetic spectrum space in operational scenario. Intelligent Radios will be the weapon of future age warfare by aiding in efficient spectrum management, powerful electromagnetic warfare in active mode and easy and quick decision making leading to timely escalation and achievement of tactical, strategic, and political objectives. </p>
Q-Factor Parasitic Aware Based Multi-Diode RF Energy Harvesting Scheme for Battery-Less RFID Applications
Authors: Pathak Deepali 
Published: November 2023

<p>This article proposes a multi-diode-based wide-input power range rectifier for harvesting ambient radio frequency (RF) energy from 915 MHz ultra-high frequency (UHF). L-match series and parallel topology have been designed to not only boost the received input power but also to produce a highly efficient network to hold a broad input power range. A quality factor based parasitic aware impedance transformation technique are introduced to minimize the rectifier circuit design complexity. This paper demonstrates theoretically and practically that a parallel network is more effective than a series network due to greater harmonic suppression results in an improvement of 3 to 8 percent efficiency throughout a power range of 26 dBm to 12 dBm at a desired frequency. The design utilizes Multi diode (SMS7630, HSMS2850, and HSMS2862) approach to achieve higher efficiency over a wide input power range. From the measurements, the proposed series L match achieves peak power conversion efficiency of 75% at 4 dBm with 35 dB of wide input power range from 23 dBm to 12 dBm with > 20% respectively whereas the proposed parallel L match achieves peak power conversion efficiency of 79% at 4 dBm with 38 dB of wide input power range from 26 dBm to 12 dBm with > 20% in an area of 1:8 X 2 cm 2 respectively.</p>
