Purpose:
This study evaluated the efficacy of a 4-week straw phonation in water (SPW) exercise program on aging-related vocal fold atrophy (VFA), with a secondary objective to examine the immediate effects of SPW exercises.

Method:

Thirty-eight older adults aged 60 years and above formally diagnosed with aging-related VFA were randomly assigned into an experimental group undergoing SPW exercises with an 8-cm depth of straw submersion into water for 4 weeks plus vocal hygiene practice (
n
= 20), and a control group with only vocal hygiene practice (
n
= 18). Outcome measures included laryngeal endoscopic measures of glottal gap, auditory-perceptual ratings of voice quality, acoustic measures, aerodynamic measures, and standardized self-assessment questionnaire scores. An additional round of acoustic and aerodynamic assessment following 20 min of SPW exercises was conducted to examine the immediate effects.

Results:
Significant improvements in normalized glottal gap area, perceptual rating of breathiness, smoothed cepstral peak prominence, harmonics-to-noise ratio (HNR), mean oral airflow, subglottal pressure and laryngeal airway resistance at comfortable loudness, Voice-related Quality of Life scores, and Chinese Vocal Fatigue Index Factor 3 scores were observed in the experimental group relative to the control group. There were also significant immediate effects for HNR, mean oral airflow, subglottal pressure, and laryngeal airway resistance.

Conclusions:
These findings suggested significant immediate improvements in vocal function following SPW exercises, with additional significant improvements in vocal function as well as significant improvements in quality of life following the 4-week SPW exercise program. Further studies with more long-term follow-up are recommended to better understand the efficacy of SPW exercises with deep levels of straw submersion into water as an effective clinical option for the management of hypofunctional dysphonia associated with aging-related VFA.
A distributed consensus based algorithm for economic dispatch over time‐varying digraphs
Authors: Xu Keng , Guo Fanghong , Yan Gangfeng 
Published: July 2023

AbstractIn this paper, a consensus based fully distributed optimization algorithm is proposed for solving economic dispatch problem (EDP) in smart grid. Since the incremental cost of all buses reach consensus when the optimal solution is achieved, it is selected as a consensus variable. An additional variable at each bus, called “surplus” is added to record the local power mismatch, which is used as a feedback variable to purse the balance between power supply and demand. Different from most of the existing distributed methods which require the communication network to be balanced, the algorithm uses a row random matrix and a column random matrix to precisely steer all the agents to asymptotically converge to a global optimal solution over a time‐varying directed communication network. Due to the use of a fixed step size, the proposed algorithm also outperforms other algorithms in terms of convergence speed. The graph and eigenvalue perturbation theories are employed for the algorithm convergence analysis, and the upper bound of the parameters required for convergence is given theoretically. Finally, the performance and scalability of the proposed distributed algorithm are verified by several case studies conducted on the IEEE 14‐bus power system and a 200‐node test system.

Published: July 2023

AbstractModel Predictive Control (MPC) and Direct Power Control (DPC) are widely used in Doubly Fed Induction Generator (DFIG) applications. However, in the context of DPC‐based MPC for DFIG, there has been a lack of literature focusing on the design of the MPC parameters. In this way, this article introduces a novel technique for designing weighing matrices in Direct Power Model Predictive Control using the Fake Algebraic Riccati Equation (FARE). As FARE is associated with the infinite receding horizon, a small receding horizon can be designed without compromising the robustness. Furthermore, this article presents a computationally efficient linear state‐space model for DPC that, when combined with a small receding horizon FARE design, offers a controller with low computational cost and robustness. The proposed theory is validated through experimental results under normal operation, variable speed operation, and parameter variations. Additionally, the proposed controller is compared to other MPC approaches.

Zufriedenheit von Patient*innen und
diversitätssensible Angebote – eine quantitative
Sekundärdatenanalyse
Authors: Kempny Christian , Brzoska Patrick 
Published: July 2023

Zusammenfassung
Hintergrund Die Versorgungszufriedenheit hat einen Einfluss auf die
Weiterempfehlung und auf die finanzielle Performance eines Krankenhauses. Unklar
ist, wie sich diversitätssensible Angebote auf die
Versorgungszufriedenheit auswirken.
Ziel Ziel dieser Studie ist es herauszufinden, wie sich das Angebot
einzelner Maßnahmen der diversitätssensiblen Versorgung im
Krankenhaus auf die Zufriedenheit von Patient*innen auswirkt.
Methode Für diese Studie wurden Daten zur Zufriedenheit von
Patient*innen mit Daten aus den Qualitätsberichten zu
diversitätssensiblen Angeboten in den Bereichen Religion und Sprache,
Angebote für Menschen mit einer Behinderung und Strukturmerkmalen
verknüpft. Insgesamt ergab sich so eine Stichprobe von 1460
Krankenhäusern in Deutschland. Mithilfe einer multivariablen
Regressionsanalyse wurde der Einfluss einzelner Maßnahmen auf die
Versorgungszufriedenheit bestimmt.
Ergebnisse Mehr Angebote im Bereich der Religion führen zu einer
signifikant sinkenden Zufriedenheit (B=−0,65). Mehr Angebote
für die Unterstützung von sprachlicher Diversität
steigern die Zufriedenheit signifikant (B=0,28). Die Strukturmerkmale
Krankenhausgröße (B=−1,57 bis
B=−3,78), Trägerschaft (freigemeinnützig:
B=2,03 und privat: B=0,17) und Bundesland
(B=−1,42 bis B=4,50) haben ebenfalls einen signifikanten
Einfluss auf die Zufriedenheit der Patient*innen. Angebote für
Menschen mit einer Behinderung haben keinen Einfluss auf die
Zufriedenheitswerte.
Schlussfolgerung Die Bedeutung von diversitätssensiblen Angeboten
für die Zufriedenheit der Patient*innen kann in dieser Studie
zum Teil dargestellt werden. Einzelne Maßnahmen müssen
allerdings vor verschiedenen Fragestellungen weiter betrachtet werden, um die
genaue Auswirkung auf einzelne Personengruppen festzustellen.

Zusammenfassung
Hintergrund Für die ärztliche Qualifikation ist zwischen
dem Studium und der sich daran anschließenden fachärztlichen
Weiterbildung zu unterscheiden Die reale Dauer des Zeitraums zwischen
Approbation und fachärztlicher Anerkennung wird in Deutschland derzeit
nicht systematisch erfasst.
Ziel der Arbeit Mit dieser Studie soll die reale Dauer der
fachärztlichen Weiterbildung in Deutschland untersucht werden. Die
vorliegende Arbeit befasst sich mit dem Einfluss der Fachgebietswahl, einer
Teilzeittätigkeit sowie der Abitur- und Abschlussnote im Medizinstudium,
dem Geschlecht und dem Elternstatus auf die tatsächliche Dauer der
fachärztlichen Weiterbildung.
Material und Methoden Datenbasis der KarMed-Studie ist die postalischen
Befragung einer Kohorte, die im Jahrgang 2008/09 ihr Praktisches Jahr
absolviert hat und anschließend während sieben Messzeitpunkten
– zuletzt in 2019 – während ihrer fachärztlicher
Weiterbildung begleitet wurde. Ausgewertet wurden Daten, die zum sechsten bzw.
siebten Messzeitpunkt, sechs und zehn Jahre nach der Approbation erfasst
wurden.
Ergebnisse Die Mehrheit der Ärztinnen und Ärzte konnte die
fachärztliche Weiterbildung in der Minimalzeit abschließen,
dabei hatte die Fachgebietswahl einen signifikanten Einfluss auf die
Abschlusshäufigkeiten. Bezüglich der Dauer der
fachärztlichen Weiterbildung konnte gezeigt werden, dass insbesondere
Ärztinnen nach zehn Jahren zu einem Drittel noch keine
Facharztanerkennung erreicht hatten. Dabei hatte der Elternstatus einen
signifikanten Effekt in Bezug auf den Abschluss der fachärztlichen
Weiterbildung bei Ärztinnen, nicht aber bei Ärzten.
Regressionsanalytisch (R²corr=0,03, p<.001) ließ
sich zeigen, dass der Stand der Weiterbildung mit der Abschlussnote des
Medizinstudiums assoziiert ist (β=.30). Die Zufriedenheit mit
der fachärztlichen Weiterbildung wurde von Ärzten höher
eingeschätzt wird als von Ärztinnen.
SchlussfolgerungDie Auswertungen der KarMed Studie zeigen, dass weiterhin
Nachbesserungsbedarf besteht, damit die Vereinbarkeit von Beruf und Familie
für Ärztinnen gewährleistet werden kann.
Zukünftige Studien sollten auch die Untersuchung der Auswahlverfahren
der Hochschulen und deren Zusammenhang auf die Dauer der Weiterbildung
untersuchen
A Study on the Clinical Significance of Blood Exosomal PD-L1 in
Non-Small Cell Lung Cancer Patients and its Correlation with PD-L1 in Tumor
Tissues

Published: July 2023

AbstractExosomal programmed cell-death ligand 1 (ePD-L1) can influence immune inhibition
and dysfunction. We were dedicated to unearthing the relation between ePD-L1 in
blood and pathological characteristics as well as PD-L1 in tumor tissues. We
recruited 65 non-small cell lung cancer (NSCLC) patients for exosome extraction
and detected the blood ePD-L1 expression in these patients by enzyme-linked
immunosorbent assay (ELISA) method. Besides, the correlation between blood
ePD-L1 and patients’ pathological characteristics was also analyzed. The
expression of PD-L1 in tumor tissues was tested by immunohistochemistry (IHC)
and its correlation with blood ePD-L1 expression level was analyzed by Spearman
correlation coefficient. No significant correlation was observed in PD-L1
expression levels between blood-derived exosome and tumor tissue. Altogether,
high blood ePD-L1 expression was relevant to NSCLC progression, while no such
relevance to PD-L1 expression in tumor tissue.
The Detection of Date Shifting in Real-World Data

Published: July 2023

Abstract
Objectives Analysis of health care real-world data (RWD) provides an opportunity to observe the actual patient diagnostic, treatment, and outcome events. However, researchers should understand the possible limitations of RWD. In particular, the dates in these data may be shifted from their actual values, which might affect the validity of study conclusions.
Methods A methodology for detecting the presence of shifted dates in RWD was developed by considering various approaches to confirm the expected occurrences of medical events, including unique temporal occurrences as well as recurring seasonal or weekday patterns in diagnoses or procedures. Diagnosis and procedure data was obtained from 71 U.S. health care data provider organizations (HCOs), members of the TriNetX global research network. Synthetic data was generated for various degrees of date shifting corresponding to the diagnoses and procedures studied, yielding the resulting patterns when various degrees of shifting (including no shift) were applied. These patterns were compared with those produced for each HCO to predict the presence and degree of date shifting. These predictions were compared with statements of date shifting by the originating HCOs to determine the predictive accuracy of the methods studied.
Results Twenty-eight of the 71 HCOs analyzed were predicted by methodology and confirmed by their data providers to have shifted data. Likewise, 39 were predicted and confirmed to not have shifted data. With four HCOs, agreement between predicted and stated date shifting status was not obtained. The occurrence of routine medical exams, only happening during weekdays, for these U.S. HCOs was most predictive (0.92 correlation coefficient) of the presence or absence of date shifting.
Conclusion The presence of date shifting for U.S. HCOs may be reliably detected assessing whether the routine exams should always occur on weekdays.

Dual Channel Endoscopic Mucosal Resection
Authors: Saraidaridis Julia T. , Gaetani Racquel S. , Marcello Peter W. 
Published: July 2023

AbstractEndoscopic mucosal resection (EMR) is the recommended technique for colon polypectomy for nonpedunculated lesions that are >20 mm in size not requiring excision. Dual-channel EMR (DC-EMR) uses an endoscope with two working channels to facilitate easier submucosal injection, snare resection, and clip closure of polypectomy defects. There is also promising early literature indicating that this endoscopic modality can reduce the overall learning curve present for single-channel colonoscopy EMR. This chapter will describe the steps and techniques required to perform DC-EMR, potential complications, recommended postprocedure surveillance, and future directions.
George W. Bush’s post-9/11 East Asia policy: enabling China’s contemporary assertiveness
Authors: Lee Pak K. 
Published: July 2023

AbstractIt is commonly argued that China’s foreign policy and behaviour have become increasingly assertive since Xi Jinping took the reins of the Chinese Communist Party (CCP). This strategic transformation is seen as paving the way for a direct confrontation between China and the USA since the Trump presidency. Drawing on the logic of international order-building, however, this article argues that the groundwork for this strategic change was laid when Hu Jintao was leading the CCP and that what made it possible was George W. Bush’s China and East Asia policy after 9/11. Bush’s subsequent reduced interest in East Asia enabled China to fill the void left by an absence of US presence and influence in the region. This article asserts that American policy-makers may need to ponder what their order-building project to weaken and exclude an illiberal China should include.
Zooming out the microscope on cumulative cultural evolution: ‘Trajectory B’ from animal to human culture
Authors: Andersson Claes , Tennie Claudio 
Published: July 2023

AbstractIt is widely believed that human culture originated in the appearance of Oldowan stone-tool production (circa 2.9 Mya) and a primitive but effective ability to copy detailed know-how. Cumulative cultural evolution is then believed to have led to modern humans and human culture via self-reinforcing gene-culture co-evolution. This outline evolutionary trajectory has come to be seen as all but self-evident, but dilemmas have appeared as it has been explored in increasing detail. Can we attribute even a minimally effective know-how copying capability to Oldowan hominins? Do Oldowan tools really demand know-how copying? Is there any other evidence that know-how copying was present? We here argue that this account, which we refer to as “Trajectory A”, may be a red herring, and formulate an alternative “Trajectory B” that resolves these dilemmas. Trajectory B invokes an overlooked group-level channel of cultural inheritance (the Social Protocell) whereby networks of cultural traits can be faithfully inherited and potentially undergo cumulative evolution, also when the underpinning cultural traits are apelike in not being transmitted via know-how copying (Latent Solutions). Since most preconditions of Trajectory B are present in modern-day Pan, Trajectory B may even have its roots considerably before Oldowan toolmaking. The cumulative build-up of networks of non-cumulative cultural traits is then argued to have produced conditions that both called for and afforded a gradual appearance of the ability to copy know-how, but considerably later than the Oldowan.
What are the determinants of rural-urban divide in teachers’ digital teaching competence? Empirical evidence from a large sample

AbstractThe digital divide between rural and urban areas is becoming the key factors resulting educational imbalance, which might be exacerbated by differences in teachers’ digital teaching competence. Therefore, it was crucial to explore the divide and determinants of digital teaching competence between rural and urban teachers. A large-scale survey was conducted with 11,784 K–12 teachers in China (43.40% from rural schools and 56.60% from urban schools). First, this study investigated potential factors for teachers’ digital teaching competence, including information and communication technology (ICT) attitude, ICT skills, and data literacy. Second, the data indicated the digital divide existed, i.e., the ICT attitude, ICT skills, data literacy, and digital teaching competence of rural teachers were significantly lower than those of urban teachers. Third, the Blinder-Oaxaca decomposition method demonstrated that data literacy and ICT skills were the most important determinants of the divide in digital teaching competence between rural and urban teachers. Hence, our research provided important insights for policymakers, school leaders and teachers to bridge the digital divide.
Coupled three-dimensional quantum mechanical wave packet study of proton transfer in H2+ + He collisions on accurate ab initio two-state diabatic potential energy surfaces

Published: July 2023

We have carried out fully close-coupled three dimensional quantum mechanical wave packet dynamical calculations for the reaction He+H2+→HeH++H on the ground electronic adiabatic potential energy surface and on the lowest two electronic states of newly constructed ab initio calculated diabatic potential energy surfaces for the system [Naskar et al., J. Phys. Chem. A 127, 3832 (2023)]. With the reactant diatom (H2+) in its roto-vibrational ground state (v = 0, j = 0), the calculations have been carried out in hyperspherical coordinates to obtain the reaction attributes. Convergence profiles of the reaction probability with respect to the total angular momentum quantum number at different collision energies are presented for the title reaction. State-to-state as well as initial state selected integral reaction cross sections are calculated from the fully converged reaction probabilities over a range of collision energies. The integral cross section values computed using the two-state diabatic potential energy surfaces are significantly lower than those obtained using the ground electronic state adiabatic potential energy surface and are in much better agreement with the available experimental results than the latter for total energy greater than 1.1 eV. Therefore, it becomes clear that it is important to include the nonadiabatic coupling terms for a quantitative prediction of the dynamical observables.
Implementing implants: delivery efficiency, contraceptive efficacy and population outcomes in two overabundant kangaroo populations
Authors: Coulson Graeme , Wilson Michelle E. 
Published: July 2023

Context Overabundant native wildlife can pose serious challenges for managers. The most direct, immediate way to reduce density-dependent impacts is by culling, but lethal control often lacks public support. Fertility control offers a non-lethal management alternative. Aims We conducted two fertility-control projects on eastern grey kangaroos (Macropus giganteus), a common and widespread species in Australia. We aimed to evaluate three key components of an integrated fertility-control project, namely, delivery efficiency, contraceptive efficacy and population-level outcomes. Methods The two study sites on the urban fringe of Melbourne, Australia, were small reserves. Both had undergone an irruptive peak and subsequent crash, with negative impacts on animal health. Gresswell Forest (52 ha) is open forest habitat enclosed by a kangaroo-proof fence. Serendip Sanctuary (250 ha) is grassy woodland and retired pasture, with a boundary allowing kangaroo movement onto neighbouring properties. We captured kangaroos with a dart gun at night and treated all healthy adult females with subdermal levonorgestrel implants. Key results Delivery efficiency (catch-per-unit effort) was greater from a vehicle at Serendip Sanctuary than on foot at Gresswell Forest, with only a marginal decline over successive nights at both sites. Background fecundity was 91% at Serendip Sanctuary, but close to zero at Gresswell Forest. Treatment efficacy was high, being 86–100% infertility at Serendip Sanctuary and 96–100% at Gresswell Forest. At Serendip Sanctuary, the proportion of females treated never reached 75%, whereas only one female at Gresswell Forest remained untreated after 3 years. Population density at Serendip Sanctuary exceeded the target range 3 years after culling and fertility control. No culling occurred at Gresswell Forest, but fertility control apparently held population density at a moderate level, albeit much higher than the density target. Conclusions Future management at Serendip Sanctuary and Gresswell Forest will require a sustained fertility-control effort. Further culling may also be required to complement fertility control at Serendip Sanctuary, the larger, open site. Implications Contraceptive efficacy of levonorgestrel is high in kangaroos and implants can be delivered efficiently, but achieving control of a large, open population will be challenging.
