Risk of COVID-19 death in adults who received booster COVID-19 vaccinations: national retrospective cohort study on 14.6 million people in England
Authors: Ward Isobel
Published: July 2023

Importance: The emergence of the COVID-19 vaccination has been critical in changing the course of the COVID-19 pandemic, with estimates suggesting vaccinations have prevented millions of deaths worldwide. To ensure protection remains high in vulnerable groups booster vaccinations in the UK have been targeted based on age and clinical vulnerabilities.
Objective: We sought to identify adults who had received a booster vaccination as part of the autumn 2022 campaign in England yet remained at increased risk of postbooster COVID-19 death and compared to non-COVID-19 risk.
Design, Setting, and Participants: We undertook a national retrospective cohort study using data from the 2021 Census linked to electronic health records. We fitted cause-specific Cox models to examine the association between health conditions and the risk of COVID-19 death and all-other-cause death for adults aged 50-100-years in England vaccinated with a booster in autumn 2022. Our total population was 14,644,570 people; there were 6,800 COVID-19 deaths and 150,075 non-COVID-19 deaths.
Exposure: Sociodemographic characteristics (sex, age, ethnic group, region), disability, body mass index, and diagnosis of a health condition defined from QCovid2.
Main Outcomes and Measures: The primary outcome of this study was COVID-19 death. The secondary outcome was all-cause non-COVID-19 deaths.
Results: Having learning disabilities or Down Syndrome (hazard ratio=5.07;95% confidence interval=3.69-6.98), pulmonary hypertension or fibrosis (2.88;2.43-3.40), motor neuron disease, multiple sclerosis, myasthenia or Huntington’s disease (2.94, 1.82-4.74), cancer of blood and bone marrow (3.11;2.72-3.56), Parkinson’s disease (2.74;2.34-3.20), lung or oral cancer (2.57;2.04 to 3.24), dementia (2.64;2.46 to 2.83) or liver cirrhosis (2.65;1.95 to 3.59) was associated with an increased risk of COVID-19 death. Individuals with cancer of the blood or bone marrow, chronic kidney disease, cystic fibrosis, pulmonary hypotension or fibrosis, or rheumatoid arthritis or systemic lupus erythematosus had a significantly higher risk of COVID-19 death relative to other causes of death compared with individuals who did not have diagnoses.
Conclusions, and Relevance: We identify groups who are at increased risk of postbooster COVID-19 death relative to non-COVID-19 deaths. Policy makers should continue to priorities vulnerable groups for subsequent COVID-19 booster doses to minimise the risk of COVID-19 death.

Malaria continues to be a major public health issue in a number of countries, particularly in tropical regions—the emergence of drug-resistant Plasmodium falciparum encourages new drug discovery research. The key to Plasmodium falciparum survival is energy production up to 100 times greater than other parasites, primarily via the PfLDH. This study targets PfLDH with natural bioactive compounds from the Zingiberaceae family through molecular docking and molecular dynamic studies. Sulcanal, quercetin, shogosulfonic acid C, galanal A and naringenin are the Top 5 compounds with a lower binding energy value than chloroquine, which was used as a control in this study. By binding to NADH and substrate binding site residues, the majority of them are expected to inhibit pyruvate conversion to lactate and NAD+ regeneration. When compared to sulcanal and control drugs, the molecular dynamics (MD) simulation study indicated that quercetin may be the most stable molecule when interacting with PfLDH.

Published: July 2023

Cryptocarya pulchrinervia is an Indonesian indigenous plant that grows in Sumatra, Kalimantan and Papua. One of the new compounds extracted from this plant was cryptobrachytone C, which was known to be cytotoxic against cancer cells of Murine leukemia P388 with IC50 10.52 ?M. In this study, the cytotoxicity and anticancer properties of cryptobrachytone C on proliferation, apoptosis, migration and clone formation of MCF-7 and T47D breast cancer cell lines were examined, which had not previously been done before. The cytotoxicity of the compound was measured using an MTT (3- (4,5-dimethylthiazol-2- yl) -2,5-di-phenyl-tetrazolium bromide) assay. The cell proliferation was measured using a BrdU assay, and the cell apoptosis was measured using annexin-V FITC, while the cell migration was measured using a transwell filter. The cytotoxic test result demonstrated that cryptobrachytone C was cytotoxic against MCF-7 cells with IC50 12.94 ± 0.32 ?M but not against T47D cells with IC50 65.33 ± 2.33 ?M nor against normal MRC-5 cells with IC50 122.57 ± 19.84 ?M. The cell proliferation assay showed that cryptobrachytone C at IC50 concentration had antiproliferative properties against MCF-7 cancer cell lines (p < 0.05) but did not significantly reduce T47D cell proliferation (p < 0.07). Although the results of the cell apoptosis test showed that cryptobrachytone C could induce the apoptosis of the MCF-7 and T47D cells, it was insignificant (p > 0.05). The cell migration test showed that cryptobrachytone at IC50 concentrations could inhibit the migration of the MCF-7 and T47D cells. The clonogenic test showed that cryptobrachytone C at IC50 concentration can induce the inhibition of the formation of MCF-7 and T47D cell colonies. The cryptobrachytone C anti-cancer character was more significant on the MCF-7 cell line compared to the T47D. This study showed that cryptobrachytone C was cytotoxic and had potential as an anti-cancer compound against MCF-7 and T47D breast cancer cell lines.

Published: July 2023

The study focuses on the preparation and characterisation (physicochemical and mechanical) of hydroxyapatite [Ca10(PO4)6(OH)2] (HA) from sea urchin, Echinometra mathaei. Therefore, nano-sized HA prepared from sea urchin shells were collected from beaches of the Persian Gulf in Iran. Sea urchin shells were found a source of calcium carbonate in the form of aragonite (calcite) that crystallised in an organic matrix. HA is one of the polymers used in coating the nanoparticles extracted from various sources. The calcined aragonite converted to nanosized hydroxyapatite powder by chemical reaction with orthophosphoric acid while maintaining stoichiometry, Ca/P = 1.667 at 80°C. To determine the purity of the nano-hydroxyapatite (nHA) numerous analytical procedures were used. Fourier transforms infrared spectroscopy (FTIR) confirmed the presence of the peak of 961 cm-1 is related to the symmetric tensile band of the P-O bond, and the peak of 1038 cm-1 and 1091 cm-1 is related to the tensile solid absorption of the PO4 as functional groups of nHA. The nanocrystalline HA can be observed from the SEM images. Thermogravimetric analysis (TGA-DTA) demonstrates the thermal stability of nHA powder. The results show successful isolation and characterisation study of this crucial nano-material shows it is valuable in biomedical applications, particularly in bone tissue engineering. Indeed, its fabrication is easy and economical.

Owing to their availability, cost effectiveness and environmental-friendly nature, plant extracts are promising additives for fish farming. This study aims to determine the optimal dosage of fermented herbal extract (FHE)—composed of Morus alba (33.3%), Curcuma xanthorrhiza (33.3%), and Boesenbergia rotunda (33.3%)—for growth enhancement and feed utilisation efficiency of Oreochromis niloticus fingerlings. Fermentation was conducted using probiotics Lactobacillus casei (Yakult®, Tokyo, Japan) and Saccharomyces cereviceae (commercial baker’s yeast). The FHE was high in flavonoid and alkaloid, vitamin C, potassium, natrium, lipase and protease. Four doses of FHE treatments, namely treatment A (0 mg/kg of feed); treatment B (100 mg/kg of feed); treatment C (300 mg/kg of feed); treatment D (500 mg/kg of feed) were compared. After subjected to 35 days of culture, tilapias subjected to FHE-coated feed exhibited better weight gain (WG), specific growth rate (SGR), and feed efficiency (FE) compared to control. The best dosage that gave the highest growth and feed efficiency was treatment C (300 mg/kg of feed). Furthermore, the feed efficiencies of FHE-incorporated treatments were positively influenced by the increased in length and density of intestinal villi, number of goblet cells, lymphocytes, as well as nutrient retention to support growth. The results of this study indicate that FHE is a promising functional feed additive to stimulate growth and improve feed efficiency in tilapia farming.
Classicality with(out) decoherence: Concepts, relation to Markovianity, and a random matrix theory approach
Authors: Strasberg Philipp
Published: July 2023

Answers to the question how a classical world emerges from underlying quantum physics are revisited, connected and extended as follows. First, three distinct concepts are compared: decoherence in open quantum systems, consistent/decoherent histories and Kolmogorov consistency. Second, the crucial role of quantum Markovianity (defined rigorously) to connect these concepts is established. Third, using a random matrix theory model, quantum effects are shown to be exponentially suppressed in the measurement statistics of slow and coarse observables despite the presence of large amount of coherences. This is also numerically exemplified, and it highlights the potential and importance of non-integrability and chaos for the emergence of classicality.
Transitions in Xenes between excitonic, topological and trivial insulator phases: Influence of screening, band dispersion and external electric field
Authors: Pulci Olivia , Gori Paola , Grassano Davide , D'Alessandro Marco , Bechstedt Friedhelm
Published: July 2023

Using a variational approach, the binding energies E_bEb of the lowest bound excitons in Xenes under varying electric field are investigated. The internal exciton motion is described both by Dirac electron dispersion and in effective-mass approximation, while the screened electron-hole attraction is modeled by a Rytova-Keldysh potential with a 2D electronic polarizability \alpha_{2D}α2D. The most important parameters as spin-orbit-induced gap E_gEg, Fermi velocity v_FvF and \alpha_{2D}α2D are taken from ab initio density functional theory calculations. In addition, \alpha_{2D}α2D is approximated in two different ways. The relation of E_bEb and E_gEg is ruled by the screening. The existence of an excitonic insulator phase with E_b>E_gEb>Eg sensitively depends on the chosen \alpha_{2D}α2D. The values of E_gEg and \alpha_{2D}α2D are strongly modified by a vertical external electric bias UU, which defines a transition from the topological into a trivial insulator at U=E_g/2U=Eg/2, with the exception of plumbene. Within the Dirac approximation, but also within the effective mass description of the kinetic energy, the treatment of screening dominates the appearance or non-appearance of an excitonic insulator phase. Gating does not change the results: the prediction done at zero electric field is confirmed when a vertical electric field is applied. Finally, Many-Body perturbation theory approaches based on the Green’s function method, applied to stanene, confirm the absence of an excitonic insulator phase, thus validating our results obtained by ab initio modeling of \alpha_{2D}α2D.

Introduction. The most important problems of clinical characterization and timely diagnosis of a new coronavirus infection COVID- 19 have been identified. The detection and treatment of patients with COVID-1 9 in the domestic health care system are carried out according to the Provisional Methodical Recommendations “Prevention, Diagnostics and Treatment of New Coronavirus Infection”. Its basic clinical manifestations are characterized by typical symptoms of acute respiratory viral disease: fever, dry cough, stuffy nose, headache, etc.

Objective. To study the nature of clinical manifestations of new coronavirus infection COVID-1 9, associated with delta strain of SARS-CoV-2 coronavirus with moderate and severe course.

Materials and methods. We analyzed the course of the disease in 50 patients treated as inpatients at Saransk Covid Hospital. Questionnaires to analyze complaints and anamnesis of diseases, data of medical records of in-patients were used. We used visual analog scale (VAS) to estimate the intensity of non-specific neurological disturbances, decreased sense of smell, taste and hearing, where 0 point means no neurological disturbance, 10 points – expressed disturbance. The presented data allowed to analyze the general, nonspecific and specific neurological manifestations of the new coronavirus infection COVID- 19 in the acute period in patients with moderate and severe course and to reveal their peculiarities.

Results. At a moderately severe course of the disease, the characteristic symptoms of respiratory infection in combination with depressed mood and anxiety predominated. Of nonspecific neurological disorders, sleep disturbances, dizziness, and of specific manifestations, impaired sense of smell and taste prevailed. At a severe course the above symptoms were joined by myalgia, headache, dyspnea and shortness of breath, gastrointestinal disorders.

Conclusions. The severity of the course of COVID-1 9 coronavirus infection, associated with the delta strain of SARS-CoV-2 coronavirus, is determined by the severity of the generalized manifestations, involvement of the lower respiratory tract, gastrointestinal disorders.
Insomnia and anxiety in older adults
Authors: Pizova N. V. , Pizov A. V.
Published: July 2023

A share of older persons among the general population has been increasing. Mental health is the most important determinant of health status of older people. Anxiety in later life is the most common mental disease. Various diseases and symptoms often occur at the advanced age. In older adults, anxiety disorders are associated with an increased risk of comorbidities. Although insomnia is not a normal part of the ageing process, its prevalence increases with age. Many older people experience dissatisfaction with the quantity and quality of sleep, even if they get enough sleep. Ageing is associated with some changes in parameters of sleep architecture and continuity. There are several demographic, psychosocial, biological, and behavioural factors that may contribute to insomnia later in life. Older people are subject to greater risk for the physical and mental consequences of insomnia. Patients with long-term insomnia usually experience anxiety and depression. Evidence suggests that there is a complex bidirectional relationship between insomnia and anxiety in the elderly. Sleep disturbances are part of the anxiety disorder pattern. Therefore, healthcare workers must obtain comprehensive information about the health and sleep status of older people to correctly diagnose insomnia, anxiety, and identify potential correlates of these disorders. Taking a careful and complete medical history and performing a thorough physical examination is the most important aspect of their evaluation. If insomnia and anxiety are diagnosed in later life, therapy should include non-drug and drug treatments, taking into account possible side effects.

Published: July 2023

Polyneuropathies are a heterogeneous group of diseases that can be caused both by a primary lesion of peripheral nerves, and secondarily, against the background of various somatic diseases. The most common cause of chronic polyneuropathy is distal symmetrical diabetic polyneuropathy. In clinical practice, it is important to be aware of dysimmune polyneuropathy, such as Guillain Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and paraproteinemic polyneuropathy, which lead to severe motor impairment and disability in patients. Identification of the cause of polyneuropathy requires real art, which includes knowledge of the clinical, electrophysiological picture and variants of the course of the disease, as well as a wide range of conditions leading to their development. Timely diagnosis of polyneuropathies and early assignment of etiological and pathogenetic therapy reduce the risk of developing irreversible changes in peripheral nerves caused by axonal degeneration. In the treatment of polyneuropathy of various origins, a special place is occupied by B vitamins, which have a neurotropic effect. Cyanocobalamin is a pathogenetic therapy in patients with diabetes who take metformin for a long time and who developed polyneuropathy due to vitamin B12 deficiency. In one patient, a combination of several variants of polyneuropathies is possible. The article presents a clinical case of a patient with type 1 diabetes mellitus (DM) who developed dysimmune chronic inflammatory demyelinating polyneuropathy (CIDP) associated with DM on the background of distal symmetrical painless diabetic polyneuropathy after a COVID- 19 infection. A feature of the development of CIDP was the acute onset of the disease. Variants of the clinical picture, ENMG criteria, as well as features of treatment, the effectiveness of therapy and the prognosis of CIDP in patients with DM are discussed.

Authors: Ammar Mallak M.
Published: July 2023

Specific activities of phenolic compounds produced from the fruiting bodies of the fungi PO and AB (the locally produced strain in Iraq) obtained from the Department of Plant Protection - Department of Organic Agriculture - Baghdad - Iraq were studied. Then, the phenolic compounds were determined after cleaning, drying and grinding the fruiting bodies. The alcoholic extract of the two fungi was prepared by adding 0.2 g of fruiting bodies powder per (1) ml of 98% ethyl alcohol, where the mixture was filtered, concentrated and kept in the refrigerator until use. The aqueous extract was prepared by adding 25 g of fruiting bodies powder per 500 ml of boiled distilled water. Similarly, the mixture was mixed, filtered and stored in the refrigerator until use. The study findings confirmed the existence of significant differences at the probability level (P ˂ 0.05) for the alcoholic and aqueous extracts and for the fungi in the content of phenolic compounds.
Conversely, the reducing power was increased by increasing the concentrations prepared for the extracts prepared from the two fungi under study. The free radical scavenging method DPPH was used to estimate the antioxidant activity of alcoholic and aqueous extracts and of the fungi PO and AB. Thus, the results showed the superiority of ethyl acetate extract compared to the other used solvents.
Keywords: Edible fungi, phenolic compounds, reducing power, free radical scavenging.
She is an Expert in this Research Field: The Signal of Recent Publications' Relevance
Authors:   University of Haifa, Zeevi Gil , Mokryn Osnat
Published: July 2023

Assessing the expertise of researchers has garnered increased interest recently. This heightened focus arises from the growing emphasis on interdisciplinary science and the subsequent need to form expert teams. When forming these teams, the coordinators need to assess expertise in fields that are often very different from theirs. The conventional reliance on signals of success, prestige, and academic impact can unintentionally perpetuate biases within the assessment process. This traditional approach favors senior researchers and those affiliated with prestigious institutions, potentially overlooking talented individuals from underrepresented backgrounds or institutions. This paper addresses the challenge of determining expertise by proposing a methodology that leverages the relevance of a researcher's recent publication track to the proposed research as a "sensemaking" signal. We introduce a novel {\em $\alpha-$relevance} metric between the trained embedding over the titles and abstracts of a researcher's recent publications and the embedding of a call and show that high values of {\em $\alpha-$relevance} indicate expertise in the field of the call. By evaluating the {\em $\alpha-$relevance} threshold, we establish a robust framework for the assessment process. For the evaluation process, we use (1) NIH grant-winning records and researchers' publications obtained from Scopus and (2) grant submissions dataset from a research university and the corresponding researchers' publications. Additionally, we investigate the optimal time window required to capture the researcher's expertise based on their publication timeline. Considering the temporal relationship between grant winnings and publications, we identify the most informative time window reflecting the researcher's relevant contributions. The data-driven methodology transcends traditional signals of success, promoting a fair evaluation process of the researcher's relevance to the proposed research. By leveraging objective indicators, we aim to facilitate the formation of expert teams across disciplines while mitigating biases in assessing expertise.

Authors: Hernández Viveros Cristian Alejandro , Elizondo Cortés Mayra
Published: July 2023

Actualmente existe una reconversión productiva en la economía. Esto estimula el desplazamiento de mano de obra en el mercado laboral hacia nuevas actividades productivas o al desempleo. La población juvenil con educación superior es uno de los grupos más perjudicados. Esto se atribuye al desequilibrio entre demanda y oferta laboral. El objetivo del presente estudio fue generar una clasificación de las carreras profesionales en México con base en su desempeño en el mercado laboral, a través de un proceso jerárquico analítico (AHP), para brindar soporte en el proceso de selección de carrera profesional. Los resultados indicaron que las tres formaciones profesionales con mayor número de profesionistas no se encuentran dentro de las veinte primeras posiciones de la clasificación, lo cual indica un bajo requerimiento de éstos en el sistema económico. El principal aporte del trabajo es la generación de información sistémica.

Chaotic logistic map sequences with good auto-correlation properties
Authors: Laguna-Sanchez Gerardo , Aguirre-Guerrero Daniela , Robles-Martinez Ismael Ariel
Published: July 2023

In this work, chaotic sequences with good auto-correlation properties are presented. The studied sequences are synthesized by means of the logistic map function and, been chaotic but fully deterministic, become a good alternative for well-known sequences, for example the Zadoff-Chu sequences, especially for small size sequences commonly used for frame synchronization purposes in digital communications systems. A new auto-correlation goodness metric is proposed, and it is employed as objective function in order to maximize the correlation goodness for short synchronization sequences synthesized by means the logistic map function.

The properties of hydroxyapatite (HAp) obtained from tilapia (Oreochromis niloticus) bones and its potential use as a dye adsorbent using methyl orange (MO) as a model dye were evaluated. HAp was produced by the calcination of dried tilapia bones at 900 °C for 4 h. Then, HAp was characterized using thermogravimetric (TGA) and differential thermogravimetric (dTG) analyses, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM), x-ray diffraction (XRD), among others. The HAp obtained was used for MO dye adsorption in a batch process. The yield of HAp was 51.6%. FTIR showed characteristic bands of functional groups of HAp [OH- and (PO4)3-]. FESEM images showed HAp with different morphologies and a porous surface. The EDS analysis indicated the presence of calcium and phosphorus with an atomic ratio of Ca/P of 1.60, TEM images revealed the formation of agglomerates and an average particle size of 655.1 nm. HAp and β-tricalcium phosphate (β-TCP) phases were identified through XRD. The HAp point of zero charge (pHpzc) was 9.7 indicating a possible adsorption of anionic dyes at pH< pHpzc and cationic dyes at pH> pHpzc. The HAp was able to successfully adsorb 82.6% of MO dye from aqueous solution. These findings demonstrated that the HAp obtained from tilapia (O. niloticus) bones possesses suitable properties to be used as a potential material to remove dyes.

This paper investigates the relationship between Islamic religiosity and excessive conspicuous luxury consumption (israf) in Indonesia, the largest Islamic society in the world. This paper is the first of research projects that examined the relationship between religiosity and israfin the scale of the country. This study uses a probit model estimation model using STATA 12 software. The data set being used is Indonesia Family Life Survey 5 (IFLS5), which consists of a 5.646 Moslem family sample (>20.000 individual Moslems) representing about 83% of the Indonesian population living in 13 of the 26 provinces in Indonesia. This paper examined the relationship between Islamic religiosity (identity religiosity, intrinsic religiosity, extrinsic religiosity) and excessive conspicuous luxury consumption (israf). The result is no relationship between Islamic religiosity and Israf in Indonesia. Identity, intrinsic and extrinsic religiosity insignificantly corresponds to israf. The findings of the paper can be a suggestion for Islam in teachings about israf, which can be more emphasized in the family by the parents, to be included in the school curriculum, and in prayer meetings by the religious leader in order to make having an Islam religiosity can have a significant negative relationship to israf lifestyle.
Utilizing Creator Profiles for Predicting Valuable User Enhancement Reports

Published: July 2023

Users of software applications use Issue Tracking Systems (ITSs) to file
enhancement reports, which leads to a large quantity of user requests.
Indeed, these reports have become an important source for software
requirements because they help to continuously improve software
applications. Usually, developers and maintainers evaluate them and
decide which user reports can be accepted. However, enhancement reports
are continuously being raised one after another, which makes this
process time-consuming and labor-intensive. Timely handling and
implementation of these enhancement reports can effectively improve user
satisfaction and product competitiveness. Thus, research has focused on
automated methods for predicting which enhancement reports are likely to
be approved, to maximum the value derived from user reports. However,
reported results of existing approaches are typically not good enough
for practical use. In this paper, we propose a novel
creator-profile-based method to explore dependencies among enhancements
to improve the prediction performance. Firstly, we define the concept of
a creator profile, including a general method of how to generate creator
profiles from the data set. Then we explain how to employ creator
profiles to the problem of enhancement report approval prediction.
Finally, we evaluate our approach on 40,551 enhancement reports
collected from ITSs. The experimental results indicate that our proposed
approach greatly improve on existing state of the art, especially in
predicting approved reports. For cross-application prediction, the
accuracy is 80.7%, while for non-cross-application prediction, the
overall accuracy is 83.6%. That is, with the proposed approach, over
80% of user requests can be automatically identified for exacting
valuable user requirements, which significantly reduces labor costs.

Diagnosis of pediatric obstructive sleep apnea hypopnea syndrome using a risk score based on polysomnography sleep video recordings: a pilot study
Authors: Akkari Mohamed , Nicolas Saroul , Petersen Jens Erik , Lambert Céline , Puechmaille Mathilde , Gilain Laurent , Mom Thierry , Dauvilliers Yves , Fantini Maria Livia , Beudin Patricia
Published: July 2023

Objectives: Because access to sleep recordings is limited,
there is a need for new reliable diagnostic tools for pediatric
obstructive sleep apnea-hypopnea syndrome (OSAHS) diagnosis. A score
calculated from a 30 minutes-home sleep videotape recording has already
been proposed in 1996 with interesting results. The main objective of
this pilot study was to assess the reliability of a similar score
applied to reference PSG video recordings and calculated on two
different time windows (30 and 10 minutes). Methods: Sixteen
children suspected of OSAHS, aged between two and ten years, underwent
video recording during overnight PSG. Video analysis was made during the
second complete sleep cycle. A 30-minute risk score (RS30) and a
10-minute risk score (RS10) were established by analyzing seven
parameters. The RS30 and RS10 were correlated with clinical examination
data, a sleep questionnaire, the obstructive-apnea-hypopnea index (OAHI)
and the oxygen desaturation index (ODI) from synchronized PSG results.
Results: There was a significant correlation between both the
RS30 and RS10, the OAHI and ODI. A RS30 ≥ 6.09 was predictive of an OAHI
≥ 5 per hour with a sensitivity of 83% and a specificity of 90%. A
RS10 ≥ 6.50 was predictive of an OAHI ≥ 5 per hour with a sensitivity of
67% and a specificity of 100%. Conclusion: A risk score based
on PSG video recordings shows a good correlation with PSG results,
confirming previous reports. Further work should focus on applying this
risk score to home sleep video recordings for the diagnosis of pediatric
OSAHS.
A new robust fractional order sliding mode control considering interval mismatch for fractional order uncertain time-varying delay systems
Authors: Jin Yitong , Li Ping , Zhou Xingde , Wang Chunxiu
Published: July 2023

Abstract This paper concentrates on the robust fractional
sliding mode control for fractional uncertain time-varying delay systems
in order (0,1). By providing a novel Lyapunov–Krasovskii function, some
novel conditions considering interval mismatch are derived to obtain a
linear quadratic regulator (LQR) based fractional sliding mode control
(SMC) strategy. Based on a fractional order integral matrix inequality
and linear matrix inequality (LMI) approach, the conditions are less
conservative and easy to solve. The control law is designed by using
hyperbolic tangent function to reduce chattering phenomenon. The
proposed conditions can be solved using some standard numerical
packages. Two examples are provided to verify the effectiveness of the
introduced theoretical formulation.

Published: July 2023

This survey paper offers a comprehensive review of the recent
advances and applications of Machine Learning (ML) approaches in the
interdisciplinary field of bioengineering, specifically in the realm of
biosignal processing. Biosignals, including electroencephalograms (EEG),
electrocardiograms (ECG), and electromyograms (EMG), are inherently
complex, presenting significant challenges such as noise, artifacts,
variability, and nonlinearity in their processing. However, ML has shown
promise in overcoming these hurdles, enabling the extraction of useful
features and insights from these signals. The paper outlines how ML is
leveraged for processing, analyzing, classifying, and interpreting
biosignals for various applications, such as diagnosis, monitoring,
rehabilitation, and brain-computer interfaces. Additionally, it
discusses the ongoing challenges and potential future directions of ML
applications in this field. Through this review, we aim to highlight the
critical role of ML in enabling adaptive, personalized, and intelligent
systems that interact with biosignals in real-time, with potential
implications for improving patient outcomes in various medical
conditions.
THE GLOBAL UNIQUENESS OF A DISSIPATIVE FRACTIONAL HELMHOLTZ EQUATION
Authors: ZHANG WENJING , ZHANG YU
Published: July 2023

In this paper, we consider the Dirichlet problem of the fractional
Helmholtz equation with dissipation, as well as study the inverse
problem of determining the source function, potential function and
dissipation of the equation by Dirichlet to Neumann (DtN) map and Runge
approximation. We prove the global uniqueness of the three functions of
the equation under low-frequency conditions. As the main result, it
implies that one can use the external data to uniquely recover the
unknown function of the equation in low-frequency case, and will be of
important significance in photoacoustic tomography and thermoacoustic
tomography.
A Historical Overview of the Computerization of the Internal Revenue Service
Authors: Neuman Erica L.
Published: July 2023

The Internal Revenue Service (IRS) is charged with enforcing the U.S. tax code and has historically fulfilled this charge efficiently. The IRS is among the most cost-effective government agencies, costing just 33 cents for each $100 it collects (Internal Revenue Service (IRS) 2021a). The effectiveness of the agency is associated with factors like a relatively high voluntary compliance rate and the use of technology to improve audits and enhance taxpayer service. Technology-supported audits have dual roles; they increase perceived detection, which deters noncompliance, and they increase actual detection, which identifies noncompliers; both roles help to improve revenue collection. Technology-supported taxpayer service increases the cost-efficiency of the agency and taxpayer satisfaction. This study provides a historical overview of the computerization of the IRS, noting obstacles, like budget constraints, politicization of the agency, historically short leadership tenure, risks associated with private-sector contracts, and taxpayer privacy concerns.
