Published: June 2023

Abstract5G cellular networks have recently fostered a wide range of emerging applications, but their popularity has led to traffic growth that far outpaces network expansion. This mismatch may decrease network quality and cause severe performance problems. To reduce the risk, operators need long term traffic prediction to perform network expansion schemes months ahead. However, long term prediction horizon exposes the non-stationarity of series data, which deteriorates the performance of existing approaches. We deal with this problem by developing a deep learning model, Diviner, that incorporates stationary processes into a well-designed hierarchical structure and models non-stationary time series with multi-scale stable features. We demonstrate substantial performance improvement of Diviner over the current state of the art in 5G network traffic forecasting with detailed months-level forecasting for massive ports with complex flow patterns. Extensive experiments further present its applicability to various predictive scenarios without any modification, showing potential to address broader engineering problems.

Abstract
Hepatic encephalopathy (HE) is a neurological disease occurring in patients with hepatic insufficiency and/or portal-systemic blood shunting based on cirrhosis. The pathogenesis is not completely clear till now, but it is believed that hyperammonemia is the core of HE. Hyperammonemia caused by increased sources of ammonia and decreased metabolism further causes mental problems through the gut–liver–brain axis. The vagal pathway also plays a bidirectional role in the axis. Intestinal microorganisms play an important role in the pathogenesis of HE through the gut–liver–brain axis. With the progression of cirrhosis to HE, intestinal microbial composition changes gradually. It shows the decrease of potential beneficial taxa and the overgrowth of potential pathogenic taxa. Changes in gut microbiota may lead to a variety of effects, such as reduced production of short-chain fatty acids (SCFAs), reduced production of bile acids, increased intestinal barrier permeability, and bacterial translocation. The treatment aim of HE is to decrease intestinal ammonia production and intestinal absorption of ammonia. Prebiotics, probiotics, antibiotics, and fecal microbiota transplantation (FMT) can be used to manipulate the gut microbiome to improve hyperammonemia and endotoxemia. Especially the application of FMT, it has become a new treated approach to target microbial composition and function. Therefore, restoring intestinal microbial homeostasis can improve the cognitive impairment of HE, which is a potential treatment method.

Published: June 2023

AbstractThe contra‐rotating machine (CRM) has been a preferable selection of the contra‐rotating propulsion system (CRPS) owing to its high efficiency, high compactness, and low noise. However, the conventional CRM with rotating stator has the problem of brush and slip ring, and the conventional brushless CRM has the problem of coordinated control of equal and opposite torque. Aiming at the above problems, this article proposes a transverse‐dislocated magnetic‐field modulated brushless contra‐rotating machine (TDMFM‐BCRM). The proposed TDMFM‐BCRM has some advantages of no rotating winding, no associated brushes and slip rings, and equal and opposite torques at any time, therefore it has good potential for the CRPS. The working principle of the TDMFM‐BCRM including three dimensional magnetic‐field modulated theory, back electromotive force (EMF) generation, and torque relation is studied. Then, the influences of main parameters including magnetic block parameters and PM sizes on torques are investigated. The critical electromagnetic performances of the TDMFM‐BCRM are analysed. A prototype of TDMFM‐BCRM is manufactured and measured to validate the above analysis. Finally, the comparison of the TDMFM‐BCRM and the existing schemes are analysed.

Context. Hub-filament systems are suggested to be the birth cradles of high-mass stars and clusters.
Aims. We investigate the gas kinematics of hub-filament structures in the G333 giant molecular cloud complex using 13CO (3–2) observed with the APEX/LAsMA heterodyne camera.
Methods. We applied the FILFINDER algorithm to the integrated intensity maps of the 13CO J = 3–2 line to identify filaments in the G333 complex, and we extracted the velocity and intensity along the filament skeleton from moment maps. Clear velocity and density fluctuations are seen along the filaments, allowing us to fit velocity gradients around the intensity peaks.
Results. The velocity gradients we fit to the LAsMA and ALMA data agree with each other over the scales covered by ALMA observations in the ATOMS survey (<5 pc). Changes in velocity gradient with scale indicate a funnel structure of the velocity field in position-position-velocity (PPV) space. This is indicative of a smooth, continuously increasing velocity gradient from large to small scales, and thus is consistent with gravitational acceleration. The typical velocity gradient corresponding to a 1 pc scale is ~1.6 km s−1 pc−1. Assuming freefall, we estimate a kinematic mass within 1 pc of ~1190 M⊙, which is consistent with typical masses of clumps in the ATLASGAL survey of massive clumps in the inner Galaxy. We find direct evidence for gravitational acceleration from a comparison of the observed accelerations to those predicted by freefall onto dense hubs with masses from millimeter continuum observations. On large scales, we find that the inflow may be driven by the larger-scale structure, consistent with the hierarchical structure in the molecular cloud and gas inflow from large to small scales. The hub-filament structures at different scales may be organized into a hierarchical system extending up to the largest scales probed through the coupling of gravitational centers at different scales.
Conclusions. We argue that the funnel structure in PPV space can be an effective probe for the gravitational collapse motions in molecular clouds. The large-scale gas inflow is driven by gravity, implying that the molecular clouds in the G333 complex may be in a state of global gravitational collapse.

Context. Wide-field radio continuum observations of galaxy clusters are revealing an increasing number of spiral galaxies hosting tens of kiloparsec-length radio tails produced by the displacement of nonthermal interstellar medium (ISM) by ram pressure.
Aims. We present a semi-empirical model for the multifrequency radio continuum emission from ram-pressure-stripped tails based on the pure synchrotron cooling of a radio plasma moving along the stripping direction with a uniform velocity.
Methods. We combine LOFAR and uGMRT observations at 144 and 400 MHz to study the flux density and spectral index profiles of the radio tails of seven galaxies in Abell 2255, and use the model to reproduce the flux density and spectral index profiles, and infer the stripped radio plasma velocity.
Results. For five out of these seven galaxies, we observe a monotonic decrease in both flux density and spectral index up to 30 kpc from their stellar disk. Our model reproduces the observed trends with a projected radio plasma bulk velocity of between 160 and 430 km s−1. This result represents the first indirect measurement of the stripped, nonthermal ISM velocity. The observed spectral index trends indicate that the synchrotron cooling is faster than the adiabatic expansion losses, suggesting that the stripped radio plasma can survive for a few tens of million years outside of the stellar disk. This provides a lower limit on the lifetime of the stripped ISM outside of the disk. As a proof of concept, we use the best-fit velocities to constrain the 3D velocity of the galaxies in the cluster to be in the range of 300−1300 km s−1. We estimate the ram pressure affecting these galaxies to be between 0.1 and 2.9 × 10−11 erg cm−3, and measure the inclination between their stellar disk and the ram pressure wind.
Die ESC-Leitlinie 2022 zu ventrikulären Arrhythmien im internationalen Vergleich
Authors: Könemann Hilke , Eckardt Lars 
Published: June 2023

ZusammenfassungKürzlich veröffentlichte die Europäische Gesellschaft für Kardiologie die aktualisierte Leitlinie zu ventrikulären Arrhythmien und plötzlichem Herztod, die sich neben internationale
Empfehlungen amerikanischer und kanadischer Fachgesellschaften einreiht. Trotz großer gemeinsamer Basis zeigen sich in einigen Aspekten relevante Unterschiede: Die ESC-Leitlinie zeichnet
sich durch einen besonderen Schwerpunkt auf praxisnahen Übersichten und Algorithmen aus. Im Vergleich werden genetische Diagnostik und kardiale MRT aufgewertet. Im Akutmanagement stimmen
die internationalen Empfehlungen größtenteils überein. Im Langzeitmanagement bleibt die optimale Behandlung der Grunderkrankung essenziell. Die ESC-Leitlinie weist mit Einbeziehung
klinischer, genetischer und bildmorphologischer Kriterien den Weg zu einer noch individualisierteren Versorgung mit implantierbarem Kardioverter-Defibrillator (ICD). Der Stellenwert der
Katheterablation wird vor allem bei idiopathischen Arrhythmien und rezidivierenden Arrhythmien auf dem Boden einer koronaren Herzerkrankung (KHK) aufgewertet.

AbstractIn recent years, a number of new therapies have led to advances in the treatment of patients with advanced breast carcinoma. These substances are mainly CDK4/6 inhibitors and other
substances that can overcome endocrine resistance, oral selective estrogen receptor degraders, antibody drug conjugates (ADCs), and PARP inhibitors. This review summarizes and evaluates
the latest study results that have been published in recent months. This includes the overall survival data of the Destiny-Breast03 study, the first analysis of the CAPItello-291 study,
the comparison of CDK4/6 inhibitor treatment with chemotherapy in the first line of therapy (RIGHT Choice study), the first analysis of the Destiny-Breast02 study in the treatment setting
after T-DM1 treatment, and the first analysis of the Serena-2 study.Most of these studies have the potential to significantly change the therapeutic landscape for patients with advanced breast carcinoma and show that the continued rapid development of new
therapies is always producing new results.

Published: June 2023

Abstract
Background One of the goals of the St. Vincent Declaration was to reduce
serious complications of diabetes, including strokes. However, it remains
uncertain whether this goal has been achieved. Study aim: To evaluate the
incidence of stroke in the diabetic population and its differences regarding
sex, ethnicity, age, and region, to compare the incidence rate in people with
and without diabetes, and to investigate time trends.
Materials and methods A systematic review was conducted according to the
guidelines for meta-analysis of observational studies in epidemiology (the MOOSE
group) and the PRISMA group guidelines.
Results Nineteen of the 6.470 studies retrieved were included in the
analysis. The incidence of stroke in the population with diabetes ranged from
238 per 100,000 person-years in Germany in 2014 to 1191 during the 1990s in the
United Kingdom. The relative risk comparing people with diabetes to those
without diabetes varied between 1.0 and 2.84 for total stroke, 1.0 and 3.7 for
ischemic stroke, and 0.68 and 1.6 for hemorrhagic stroke. Differences between
fatal and non-fatal stroke were significant, depending on the time period and
the population. We found decreasing time trends in people with diabetes and
stable incidence rates of stroke over time in people without diabetes.
Conclusion The considerable differences between results can partly be
explained by differences in study designs, statistical methods, definitions of
stroke, and methods used to identify patients with diabetes. The lack of
evidence arising from these differences ought to be rectified by new
studies.

AbstractWe compared the effects of two 4-week strength-power-speed training protocols on
physical performance of young soccer players. Twenty-three highly trained
under-20 soccer players were randomly allocated to two mixed-training groups: 1)
“traditional” (TRAD: n=11), comprising vertically
oriented strength-power exercises and linear sprints; or 2)
“multidirectional” (MULTI: n=12), combining vertically
and horizontally oriented strength-power exercises, linear sprints, and
change-of-direction (COD) drills. Squat jump (SJ) and countermovement jump, 2)
linear sprint, COD speed, and 3) jump-squat (JS) and hip-thrust (HT) power tests
were performed pre- and post-training. Differences were determined using a
two-way ANOVA with repeated measures and “target scores” were
used to detect real changes in performance. No group-time interactions were
found for any of the variables (p>0.05). Significant increases
(p<0.05) in 20-m sprint velocity, JS- and HT-power were found
in both groups, and in SJ in TRAD. Individual analyses revealed a greater number
of meaningful changes in zig-zag velocity in MULTI while most players in TRAD
displayed meaningful increases in SJ height. In conclusion, both training
protocols resulted in similar adaptations but, at the individual level, it
appears that MULTI protocol is superior to improve COD ability while TRAD should
be preferred to maximize vertical jumping capabilities during short soccer
pre-seasons.
Lessons from Mortality Reviews: Nonbiologic Contributors to Maternal Deaths
Authors: Minkoff Howard , Chazotte Cynthia , Nathan Lisa M. 
Published: June 2023

Based on years of review and analysis of severe maternal morbidity and maternal mortality cases, it is clear that the high rates of maternal mortality in this country are due to more than obstetrical emergencies gone awry. Many nonmedical factors contribute to these poor outcomes including complex and ineffectual health care systems, poor coordination of care, and structural racism. In this article we discuss what physicians can and cannot accomplish on their own, the role of race and racism, and barriers built into the manner in which health care is delivered. We conclude that while obstetricians must continue to focus on the area where their expertise lies, reducing deaths by educating and training physicians to deal with the downstream consequences of upstream events, they must also focus increased attention on educating themselves and their trainees about the effect of racism, social disadvantage, and poor coordination of care on health, as well as their role in resolving these issues. Physicians must also reach out to their representatives in government to partner with them. Those leaders must recognize that when they hear about disparities in maternal mortality, focusing only on events in hospitals ignores the more dispositive issues that put Black women at risk in the first instance.

Scoping Review for a Global Hearing Care Framework: Matching Theory with Practice
Authors: Brice Sophie , Saunders Elaine , Edwards Brent 
Published: June 2023

AbstractThe hearing healthcare industry is evolving rapidly. A framework addressing provision options in contemporary hearing care could assist clinician and client navigate their options to find the most appropriate solution for each individual. A PRISMA approach was used followed by mapping, validation, and thematic analysis to produce a framework to better describe and discuss service and product delivery options in contemporary hearing care. No frameworks were identified to advise matching needs with current provision options in audiological care. Charting, mapping, and thematic analysis of the validation criteria and hearing care literature produced three core domains: Service, Channel, and Technology/Device. The framework developed in this review allows for an understanding of where innovation is occurring in hearing healthcare and differentiates between changes to technology, channel, and service. New questions open up such as whether one model is more effective than another or which model of hearing help is best for which type of person. This framework allows for the disambiguation of hearing health services, hearing loss technology, and the channel in which services and technology are delivered. It has potential to be a versatile and valuable addition to the industry of hearing healthcare.
Comparison of Genes Associated with Thoracic and Abdominal Aortic Aneurysms

Published: June 2023

AbstractAneurysms impacting the ascending thoracic aorta and the abdominal aorta affect patient populations with distinct clinical characteristics. Through a literature review, this paper compares the genetic associations of ascending thoracic aortic aneurysm (ATAA) with abdominal aortic aneurysms (AAA). Genes related to atherosclerosis, lipid metabolism, and tumor development are associated specifically with sporadic AAA, while genes controlling extracellular matrix (ECM) structure, ECM remodeling, and tumor growth factor β function are associated with both AAA and ATAA. Contractile element genes uniquely predispose to ATAA. Aside from known syndromic connective tissue disease and poly-aneurysmal syndromes (Marfan disease, Loeys–Dietz syndrome, and Ehlers–Danlos syndrome), there is only limited genetic overlap between AAA and ATAA. The rapid advances in genotyping and bioinformatics will elucidate further the various pathways associated with the development of aneurysms affecting various parts of the aorta.
Managers’ aspirations and quality of CSR reports: evidence from China
Authors: Hu Yuanyuan , Chen Shouming , Liu Runshi , Dai Yi 
Published: June 2023

AbstractThis study aims to investigate the potential impact of peer firms on the quality of CSR reports produced by the focal firm. By combining insights from the behavioral theory of the firm and existing literature on aspirations, this paper proposes that the aspiration levels of managers regarding CSR reporting play a crucial role in determining the quality of CSR reports. Specifically, it is suggested that the quality of CSR reports is likely to improved when the current level falls short of managers’ aspirations for CSR reporting. Conversely, when the current quality of CSR reports surpasses managers’ aspirations, it is expected to decline. Additionally, this paper proposes that this effect will be stronger when the owner of the firm is government or the firm’s visibility is high. Using a comprehensive panel dataset covering Chinese listed firms with A‐shares from 2012 to 2018, the empirical findings strongly support these arguments.

AbstractThe study’s primary objective is to advance the environmental management research field by examining the relationship between corporate social responsibility (CSR), environmental and financial performance while considering the mediating effect of sustainable development and green innovation. In addition, the study also analyzes the moderating effect of green innovation actions and green innovation strategies. Employees in the manufacturing sector in Pakistan completed a self-administered survey. Data gathered from 497 employees was analyzed using the structural analysis. The study results show that corporate social responsibility to the environment (CSREM), corporate social responsibility to employees (CSREM), to the community (CSRCO), and to the consumers (CSRCO) positively influences environmental performance (EVP) and financial performance (FP). Environmental sustainable development (ESD) and green innovation (GI) mediate the relationship between CSR, environmental, and firm financial performance. Green innovation strategies (GINS) and green innovation actions (GINAs) moderate the relationship between a firm’s environmental and financial aspects. The study deepens the understanding of CSR through an integrated model of mediator and moderator variables. It attempts to boost the firms’ performance (i.e., environmental, and financial) by applying the concept of green innovation and sustainable development. This study brings significant results for manufacturing firms, managers, entrepreneurs, policymakers, practitioners, employees, and other stakeholders. The study’s outcomes make the stakeholders adopt CSR consideration to achieve ecological and financial harmony in developing economies.
