Stability and steady state analysis of mode lock state of medium coupled microwave oscillators
Authors: Hasheminasab Marayam , Cheldavi Ahmed , Tayarani Majid , Kishk Ahmed A. 
Published: July 2023

AbstractCoupled microwave oscillators could be potentially considered a good replacement for the feed network of frequency‐diverse arrays. However, previous studies showed that the stability region for a mutually weak‐coupled oscillator array in the Mode Lock State (MLS) is too small to be practical. Besides, by increasing the coupling strength or reducing the initial natural frequency of the oscillators, the current analytical methods lose their accuracy. The final steady‐state and dynamic of a non‐linear Van‐der‐Pol medium‐coupled oscillator array in the MLS is investigated. By using the Kuramoto Model results in analysing the biological cells, an alternative approach is suggested and investigated in the entrainment region for the mode‐locked microwave oscillator array. This approach is accurate even for medium‐coupled oscillator arrays, where the locking range to the beat frequency ratio is greater than 0.1. The stability of the oscillator in this region is investigated by imposing some perturbations in the form of phase noise on the initial signals. Also, the optimum initial condition to design large arrays is investigated using the analysis results. In the described initial conditions for small beat frequencies, the simulation results show that the stability region is much greater than the large beat frequency region. This capability initiates a new practical approach for implementing Frequency Diverse Arrays.
An antenna subset selection algorithm in distributed MIMO radar for target localization via convolutional neural network
Authors: Yan Yingfei , Tao Haihong , Su Jia 
Published: July 2023

AbstractSince the distributed MIMO radar (DMR) has widely spread transmitters and receivers, it can provide higher target detection probability, as well as superior target tracking and localization performance than the monostatic/bistatic radar systems. An effective radar resource allocation scheme can optimise the DMR system parameter and obtain better system performance. In this paper, a critical but limited system resource is optimised, that is, select a subset of the active radar antennas. In this scenario, the convolutional neural network of the antenna subset selection for target localization (LCNN‐ASS) algorithm in the DMR is proposed based on two free switching policies. The proposed algorithm is immune to the failure of a single policy and selects antenna subsets from the entire sets with a remarkable computational speed. Therefore, the proposed algorithm increases the flexibility of resource scheduling over traditional algorithms. Simulation experiments and performance analysis demonstrate the localization performance and flexibility of the LCNN‐ASS algorithm.

Context. The nearby spiral galaxy NGC 3147 hosted three Type Ia supernovae (SNe Ia) in the past decades that have been the subjects of intense follow-up observations. Simultaneous analysis of their data provides a unique opportunity for testing different methods of light curve fitting and distance estimation.
Aims. The detailed optical follow-up of SN 2021hpr allows us to revise the previous distance estimations to NGC 3147 and compare the widely used light curve fitting algorithms to each other. After the combination of the available and newly published data of SN 2021hpr, its physical properties can also be estimated with higher accuracy.
Methods. We present and analyse new BV griz and Swift photometry of SN 2021hpr to constrain its general physical properties. Together with its siblings, SNe 1997bq and 2008fv, we cross-compared the individual distance estimates of these three SNe given by the Spectral Adaptive Lightcurve Template (SALT) code, and we also checked their consistency with the results from the Multi-Color Light Curve Shape (MLCS) code. The early spectral series of SN 2021hpr was also fit with the radiative spectral code TARDIS to verify the explosion properties and constrain the chemical distribution of the outer ejecta.
Results. After combining the distance estimates for the three SNe, the mean distance to their host galaxy, NGC 3127, is 42.5 ± 1.0 Mpc, which matches with the distance inferred by the most up-to-date light curve fitters, SALT3 and BayeSN. We confirm that SN 2021hpr is a Branch-normal Type Ia SN that ejected ~1.12 ± 0.28 M⊙ from its progenitor white dwarf and synthesized ~0.44 ± 0.14 M⊙ of radioactive 56Ni.

Published: July 2023

ZusammenfassungDank der Verfeinerung der Operationstechniken ist die autologe
Brustrekonstruktion inzwischen Teil der Standardversorgung geworden. Die
Beratung der Patientinnen ist aufgrund der Erweiterung der onkologischen
Möglichkeiten zur Mastektomie, Brusterhalt und Strahlentherapie und der
Vielzahl der rekonstruktiven Techniken schwieriger geworden. Ziel der
Rekonstruktion ist es, tumorzellfreie Resektionsränder und ein
langfristig ästhetisch zufriedenstellendes Ergebnis mit hoher
Lebensqualität für die Patientin zu erreichen. Bei der
sofortigen Rekonstruktion ermöglicht die hautsparende oder sogar
mamillensparende Mastektomie den Erhalt der Brusthaut und ihrer
natürlichen Form, welches das mit der Mastektomie verbundene
psychologische Trauma deutlich verringert. Jedoch weisen sekundäre
Rekonstruktionen oft eine höhere Zufriedenheit auf, da hier seitens der
Patientinnen nach erlebter Formveränderung keine Restitutio ad integrum
angenommen wird. Dieser Artikel gibt einen Überblick über die
aktuellen Möglichkeiten der Brustrekonstruktion und eine Betrachtung der
Patientinnen-Zufriedenheit und Lebensqualität nach einer
Brustrekonstruktion. Obwohl die meisten Patientinnen und Chirurg*innen
nach wie vor die sofortige Rekonstruktion bevorzugen, scheint eine
Verzögerung der Rekonstruktion die klinischen oder von den Patientinnen
berichteten Ergebnisse nicht zu beeinträchtigen. Zu den neuesten
Verfeinerungen der chirurgischen Techniken und der autologen Brustrekonstruktion
gehören „stacked-flaps“, sowie mikrochirurgische
Nervenkoaptation zur Wiederherstellung der Sensibilität, welche zu einer
Verbesserung des Ergebnisses und der Lebensqualität führen.
Heterologe, d. h. Implantat basierte, Brustrekonstruktion und autologe
Brustrekonstruktion sind mittlerweile komplementäre Techniken. Neue
Techniken wie die hautsparende und mamillensparende Mastektomie, begleitet von
verbesserter Implantatqualität, ermöglichen heutzutage eine
risikoarme sofortige prothetische Brustrekonstruktion mit präpektoraler
Implantatlage. Die Wahl der Brustrekonstruktion ist abhängig von der Art
der Mastektomie, etwaiger Bestrahlung, individuellen Risikofaktoren, dem Habitus
und den Wünschen der Patientin. Insgesamt führen die neuerlichen
Entwicklungen in der Brustrekonstruktion zu einer Erhöhung der
Patientinnen-Zufriedenheit, Lebensqualität, des ästhetischen
Ergebnisses unter onkologischer Sicherheit.

Zusammenfassung
Ziel der Studie  Das Wissen über die Folgen des
Staatsdopings in der DDR ist gering. Es wird die Hypothese untersucht, dass die
damaligen prekären Trainingsbedingungen sich bis heute negativ auf die
psychische Gesundheit der ehemaligen Leistungssportler*innen auswirken.
Methodik  Mittels Fragebögen zur psychischen
Symptomatik sowie möglichen Risiko- bzw. Schutzfaktoren wurde zwischen
ehemaligen DDR-Leistungssportler*innen und einer unselektierten
Stichprobe aus der Allgemeinbevölkerung (SHIP-LEGENDE) eine
Fall-Kontroll-Studie durchgeführt.
Ergebnisse  Auf allen
untersuchten Skalen konnten signifikante Unterschiede festgestellt werden. Der
Großteil der betroffenen Sportler*innen wies eine klinisch
relevante psychische Belastung auf. Exemplarisch hierfür ist eine
ausgeprägte depressive Symptomatik (BDI-II) bei 65,19% der
Betroffenen.
Schlussfolgerungen  Vermutlich führten
Leistungsdruck, Doping und Missbrauch im Leistungssport zu einer bis heute
messbaren Steigerung der Symptombelastung und der Vulnerabilität.
A Bibliometric Analysis of Neonatal Pain Management Research From
2010 to 2022

Published: July 2023

Abstract
Background Research related to neonatal pain management has received
increasing attention in recent years. Effective pain management contributes to
the maintenance of the healthy physical and mental growth of the newborn. To
better understand this research topic, we analyzed the current state of
development in this field over the past thirteen years by bibliometric analysis
and provide directions for future research.
Methods Original articles were collected from the Web of Science Core
Collection (WoSCC) between January 1, 2010, to December 31, 2022, the title and
abstract clearly stating ‘neonatal pain management’ or its
alternative search keywords. CiteSpace, VOSviewer, and the WoS analysis tool
were used to analyze and present the data.
Results A total of 967 articles met the inclusion criteria. Significant
growth of the number of publications increased roughly fourfold from 2010 to
2022. Overall, the United States and Canada were the highest contributors to
neonatal pain management research. Weak cooperation was observed in
international research (developing and developed countries) and
cross-institutional cooperation. Neonatal pain-related research was the most
common focus. Pain education and interventions for parents and medical personnel
have also received increasing attention recently.
Conclusion The current study revealed that research in terms of
publications on neonatal pain management has rapidly increased for more than the
past ten years. Developed countries, especially the United States and Canada,
were more concerned with this topic than developing countries. More
international research and cross-institutional cooperation are required to
promote the development of neonatal pain medicine in the future.

Authors: Combs C. Andrew , Rosario Amber del , Balogun Olaide Ashimi , Bowman Zachary S. , Amara Sushma 
Published: July 2023

Objective This study aimed to evaluate which of five established norms should be used for sonographic assessment of fetal head circumference (HC).
Study Design Cross-sectional study using pooled data from four maternal–fetal medicine practices. Inclusion criteria were singleton fetus, gestational age 220/7 to 396/7 weeks, biometry measured, and fetal cardiac activity present. Five norms of HC were studied: Jeanty et al, Hadlock et al, the INTERGROWTH-21st Project (IG-21st), the World Health Organization Fetal Growth Curves (WHO), and the National Institutes of Child Health and Human Development Fetal Growth Studies unified standard (NICHD-U). The fit of our HC measurements to each norm was assessed by these criteria: mean z-score close to 0, standard deviation (SD) of z close to 1, low Kolmogorov–Smirnov D-statistic, high Youden J-statistic, close to 10% of exams >90th percentile, close to 10% of exams <10th percentile, and close to 2.28% of exams >2 SD below the mean.
Results In 23,565 ultrasound exams, our HC measurements had the best fit to the WHO standard (mean z-score 0.10, SD of z = 1.01, D-statistic <0.01, J-statistic 0.83–0.94). The SD of the Jeanty reference was much larger than all the other norms and our measurements, resulting in underdiagnosis of abnormal HC. The means of the IG-21st and NICHD-U standards were smaller than the other norms and our measurements, resulting in underdiagnosis of small HC. The means of the Hadlock reference were larger than all the other norms and our measurements, resulting in overdiagnosis of small HC. Restricting the analysis to a low-risk subgroup of 4,423 exams without risk factors for large- or small-for-gestational age produced similar results.
Conclusion The WHO standard is likely best for diagnosis of abnormal HC. The Jeanty (Chervenak) reference suggested by the Society for Maternal-Fetal Medicine had poor sensitivity for microcephaly screening.

Published: July 2023

Abstract
Background and study aims Artificial intelligence (AI)-assisted colonoscopy has proven to be effective compared with colonoscopy alone in an average-risk population. We aimed to evaluate the cost-utility of GI GENIUS, the first marketed real-time AI system in an Italian high-risk population.

Methods A 1-year cycle cohort Markov model was developed to simulate the disease evolution of a cohort of Italian individuals positive on fecal immunochemical test (FIT), aged 50 years, undergoing colonoscopy with or without the AI system. Adenoma or colorectal cancer (CRC) were identified according to detection rates specific for each technique. Costs were estimated from the Italian National Health Service perspective.
Results Colonoscopy+AI system was dominant with respect to standard
colonoscopy. The GI GENIUS system prevented 155 CRC cases (–2.7%), 77 CRC-related deaths
(–2.8%), and improved quality of life (+0.027 QALY) with respect to colonoscopy alone. The
increase in screening cost (+€10.50) and care for adenoma (+€3.53) was offset by the savings
in cost of care for CRC (–€28.37), leading to a total savings of €14.34 per patient.
Probabilistic sensitivity analysis confirmed the cost-efficacy of the AI system (almost 80%
probability).
Conclusions The implementation of AI detection tools in colonoscopy after patients test FIT-positive seems to be a cost-saving strategy for preventing CRC incidence and mortality.
Mechanosynthesis of Fullerotetrahydroquinolines by Copper-Mediated sp3 C–H Functionalization of N,N-Dimethylanilines with [60]Fullerene
Authors: Wang Guan-Wu , Yang Huan , Ye Shi-Qi , Shao Gang , Chen Jun-Shen 
Published: July 2023

AbstractAn efficient mechanochemical copper-mediated coupling reaction of [60]fullerene with para- or meta-substituted N,N-dimethylanilines under solvent-free and ambient conditions has been developed. The present protocol provides N-methylfullerotetrahydroquinolines containing electron-withdrawing or electron-donating groups on the phenyl ring in a short reaction time and at room temperature. This reaction occurs through copper-mediated sp3 C–H functionalization of N,N-dimethylanilines under ball-milling conditions. In addition, a representative fullerotetrahydroquinoline has been applied in a perovskite solar cell device.
Anti-inflammatory strategies for hepatic encephalopathy: preclinical studies
Authors: Santos Rafaela Pinto Coelho , Toscano Eliana Cristina de Brito , Rachid Milene Alvarenga 
Published: July 2023

AbstractHepatic encephalopathy (HE) is a potentially reversible neuropsychiatric syndrome. Often, HE causes cognitive and motor dysfunctions due to an acute or chronic insufficiency of the liver or a shunting between the hepatic portal vein and systemic vasculature. Liver damage induces peripheral changes, such as in the metabolism and peripheral inflammatory responses that trigger exacerbated neuroinflammation. In experimental models, anti-inflammatory strategies have demonstrated neuroprotective effects, leading to a reduction in HE-related cognitive and motor impairments. In this scenario, a growing body of evidence has shown that peripheral and central nervous system inflammation are promising preclinical targets. In this review, we performed an overview of FDA-approved drugs and natural compounds which are used in the treatment of other neurological and nonneurological diseases that have played a neuroprotective role in experimental HE, at least in part, through anti-inflammatory mechanisms. Despite the exciting results from animal models, the available data should be critically interpreted, highlighting the importance of translating the findings for clinical essays.
Management of Pulmonary Hypertension Associated with Chronic Lung Disease

Published: July 2023

AbstractPulmonary hypertension (PH) is a common complication of chronic lung diseases, particularly in chronic obstructive pulmonary disease (COPD) and interstitial lung diseases (ILD) and especially in advanced disease. It is associated with greater mortality and worse clinical course. Given the high prevalence of some respiratory disorders and because lung parenchymal abnormalities might be present in other PH groups, the appropriate diagnosis of PH associated with respiratory disease represents a clinical challenge. Patients with chronic lung disease presenting symptoms that exceed those expected by the pulmonary disease should be further evaluated by echocardiography. Confirmatory right heart catheterization is indicated in candidates to surgical treatments, suspected severe PH potentially amenable with targeted therapy, and, in general, in those conditions where the result of the hemodynamic assessment will determine treatment options. The treatment of choice for these patients who are hypoxemic is long-term oxygen therapy and pulmonary rehabilitation to improve symptoms. Lung transplant is the only curative therapy and can be considered in appropriate cases. Conventional vasodilators or drugs approved for pulmonary arterial hypertension (PAH) are not recommended in patients with mild-to-moderate PH because they may impair gas exchange and their lack of efficacy shown in randomized controlled trials. Patients with severe PH (as defined by pulmonary vascular resistance >5 Wood units) should be referred to a center with expertise in PH and lung diseases and ideally included in randomized controlled trials. Targeted PAH therapy might be considered in this subset of patients, with careful monitoring of gas exchange. In patients with ILD, inhaled treprostinil has been shown to improve functional ability and to delay clinical worsening.
The Prevalence and Risk Factors of Contralateral Cranial Cruciate Ligament Rupture in Medium-to-Large (≥15kg) Breed Dogs 8 Years of Age or Older
Authors: Murphy Christina L. , Niles Jacqui , Radasch Robert M. 
Published: July 2023

Abstract
Objective The aim of this study was to determine the prevalence of contralateral cranial cruciate ligament rupture (CCLR) in dogs 8 years of age or older, weighing more than or equal to 15 kg at the time of first-side CCLR and to assess associated risks.
Study Design It is a cross-sectional retrospective study of 831 client-owned dogs
Methods Medical records of dogs weighing more than or equal to 15 kgs that were more than or equal to 8 years of age at the time of first CCLR diagnosis were reviewed. Data collected included weight, sex, pre-operative tibial plateau angle, co-morbidities, time between diagnosis of first CCLR and diagnosis of contralateral CCLR. Multivariate logistic regression analysis was used to estimate odds ratio. A median follow-up period of over 112.7 months (25th/75th quartiles 75.4/157.7 months) from first CCLR diagnosis was allotted.
Results Eight-hundred thirty-one dogs were identified and included. About 19.1% (159/831 dogs, 95% confidence interval: 16.6–22.0%) of dogs that experience a first-side CCLR at 8 years of age or older will rupture the contralateral side, a median of 12.9 months (25th/75th quartiles 6.5/24.3 months) later. Age (p = 0.003) and breed, Golden Retrievers (p = 0.028) and Labrador Retrievers (p = 0.007), were factors significantly associated with contralateral CCLR.
Clinical Relevance The prevalence of contralateral CCLR in medium-to-large breed dogs more than or equal to 8 years of age old is less than previously reported and the risk decreases as they age. This important information will help guide owners when deciding to pursue surgical stifle stabilization following CCLR in older dogs.
Accurate prediction of global-density-dependent range-separation parameters based on machine learning
Authors: Villot Corentin , Huang Tong , Lao Ka Un 
Published: July 2023

In this work, we develop an accurate and efficient XGBoost machine learning model for predicting the global-density-dependent range-separation parameter, ωGDD, for long-range corrected functional (LRC)-ωPBE. This ωGDDML model has been built using a wide range of systems (11 466 complexes, ten different elements, and up to 139 heavy atoms) with fingerprints for the local atomic environment and histograms of distances for the long-range atomic correlation for mapping the quantum mechanical range-separation values. The promising performance on the testing set with 7046 complexes shows a mean absolute error of 0.001 117 a0−1 and only five systems (0.07%) with an absolute error larger than 0.01 a0−1, which indicates the good transferability of our ωGDDML model. In addition, the only required input to obtain ωGDDML is the Cartesian coordinates without electronic structure calculations, thereby enabling rapid predictions. LRC-ωPBE(ωGDDML) is used to predict polarizabilities for a series of oligomers, where polarizabilities are sensitive to the asymptotic density decay and are crucial in a variety of applications, including the calculations of dispersion corrections and refractive index, and surpasses the performance of all other popular density functionals except for the non-tuned LRC-ωPBE. Finally, LRC-ωPBE (ωGDDML) combined with (extended) symmetry-adapted perturbation theory is used in calculating noncovalent interactions to further show that the traditional ab initio system-specific tuning procedure can be bypassed. The present study not only provides an accurate and efficient way to determine the range-separation parameter for LRC-ωPBE but also shows the synergistic benefits of fusing the power of physically inspired density functional LRC-ωPBE and the data-driven ωGDDML model.
