Clinical Insights Into the Use of Speech Amplification Devices for Managing Hypophonia: Interviews With Speech-Language Pathologists
Authors: Gates Kelly , Knowles Thea , Mach Helen , Higginbotham Jeff 
Published: March 2024

Purpose:
The purpose of this qualitative interview study was to identify themes regarding considerations in the usage of speech amplification device usage for people with Parkinson's disease (PD) and hypophonia from the perspective of speech-language pathologists (SLPs).

Method:
Eligible participants included SLPs currently practicing in the United States or Canada with experience working with clients with PD for at least 2 years. Ten SLPs participated in 60-min interviews conducted via Zoom. A semistructured interview guide was created prior to the interviews. The interviews were transcribed following their completion, and an iterative coding process was used to identify themes using thematic analysis.

Results:
Three main themes were identified from the interviews. The first theme encapsulated how clinicians described amplification devices as a potential treatment tool, which highlighted the nuances that may impact selecting an amplification device as a treatment option such as increased hypophonia or dysarthria severity and cognitive decline. The second theme highlighted how device selection depends on the individual needs of the user. Individual client characteristics (such as disease symptoms and individual needs and preferences) may impact the choice of amplification device. The last theme outlined the importance of involving family members in all stages of device use and involving other health care team members on a case-by-case basis.

Conclusions:
The insights provided by the SLP participants help to understand the clinical decisions that are made when determining device candidacy, selecting a device, and evaluating device success. These insights can be used to improve research studies of augmentative management of hypophonia and guide more personalized management decisions.
Noise‐tolerant matched filter scheme supplemented with neural dynamics algorithm for sea island extraction

Published: March 2024

AbstractAchieving high‐precision extraction of sea islands from high‐resolution satellite remote sensing images is crucial for effective resource development and sustainable management. Unfortunately, achieving such accuracy for sea island extraction presents significant challenges due to the presence of extensive background interference. A more widely applicable noise‐tolerant matched filter (NTMF) scheme is proposed for sea island extraction based on the MF scheme. The NTMF scheme effectively suppresses the background interference, leading to more accurate and robust sea island extraction. To further enhance the accuracy and robustness of the NTMF scheme, a neural dynamics algorithm is supplemented that adds an error integration feedback term to counter noise interference during internal computer operations in practical applications. Several comparative experiments were conducted on various remote sensing images of sea islands under different noisy working conditions to demonstrate the superiority of the proposed neural dynamics algorithm‐assisted NTMF scheme. These experiments confirm the advantages of using the NTMF scheme for sea island extraction with the assistance of neural dynamics algorithm.
Trends in der Verbreitung des Konsums psychoaktiver Substanzen in
Deutschland: Ein deskriptives Review von Bevölkerungsstudien vor, während und
nach der COVID-19 Pandemie
Authors: Kuitunen-Paul Sören , Schwarzbach Christoph P. , Atzendorf Josefine 
Published: March 2024

Zusammenfassung
Hintergrund Zwischen 2020 und 2023 galten in Deutschland aufgrund der
COVID-19 Pandemie mehrere teils bundesweite und gravierende Einschränkungen der
Bewegungsfreiheit und sozialer Kontakte. Ausgelöste Belastungen könnten den
Konsum psychoaktiver Substanzen befördern. Ob sich dies über verschiedene
bevölkerungsrepräsentative Studien hinweg und für verschiedene psychoaktive
Substanzen zeigen, soll überblicksartig betrachtet werden.
Methode Ein deskriptives Review longitudinaler, prospektiver,
bevölkerungsrepräsentativer Studien sowie retrospektiver Querschnittsstudien,
bei dem deutsche Teilnehmende zum Konsum von Alkohol, Tabak sowie verschiedener
illegaler Substanzen/Substanzgruppen einschließlich Cannabis befragt wurden.
Ergebnisse Beim Alkoholkonsum zeigten sich gegenläufige Entwicklungen mit
häufigerer Abstinenz sowie häufigerem regelmäßigen Konsum bei Erwachsenen und
schwacher Prävalenzabnahme bei Jugendlichen und jungen Erwachsenen. Die Abnahme
der Tabakkonsum-Prävalenz bis einschließlich 2021 hat sich anschließend
umgekehrt hin zu einer tendenziell zunehmenden Verbreitung.
Cannabiskonsum-Prävalenzen stiegen während der Pandemie bei Erwachsenen, ebenso
die Verbreitung zahlreicher anderer illegaler Substanzen, für die keine
Schätzungen zu Veränderungen im Jugendalter vorliegen.
Schlussfolgerung Die Ergebnisse weisen auf eine komplexe Dynamik im
Substanzkonsum hin, die möglicherweise pandemie-bedingten Veränderungen
unterworfen wurde und sich je nach Substanz und Altersgruppe unterschiedlich
darstellte. Gleichzeitig fehlen derzeit noch relevante Kennzahlen insbesondere
für Jugendliche und den Zeitraum nach der Pandemie (2022–2023).

Published: March 2024

AbstractSimulation-based training (SBT) is increasingly acknowledged worldwide and has become a popular tool for ultrasound education. Ultrasound simulation involves the use of technology and software to create a virtual training setting. Simulation-based training allows healthcare professionals to learn, practice, and improve their ultrasound imaging skills in a safe learning-based environment. SBT can provide a realistic and focused learning experience that creates a deep and immersive understanding of the complexity of ultrasound, including enhancing knowledge and confidence in specific areas of interest. Abdominal ultrasound simulation is a tool to increase patient safety and can be a cost-efficient training method. In this paper, we provide an overview of various types of abdominal ultrasound simulators, and the benefits, and challenges of SBT. We also provide examples of how to develop SBT programs and learning strategies including mastery learning. In conclusion, the growing demand for medical imaging increases the need for healthcare professionals to start using ultrasound simulators in order to keep up with the rising standards.

Published: March 2024

Abstract
Purpose Ultrasound-guided puncture and punch biopsy pose a particular challenge in ultrasound examination training. These techniques should be learned and performed several times using a simulation model that is as realistic as possible before being applied to patients. While the use of agar-agar-based models is extensively documented in the literature, there is a discernible gap in publications specifically addressing their use in punch biopsy and puncture. The aim was to develop a cost-effective model for the simulation of ultrasound-guided interventions.
Materials and Methods The developed simulation model is based on the vegetable gelatine agar-agar. The agar-agar powder is boiled in water and colored. Various objects are added to the mass. Blueberries, olives, tomatoes, and cornichons imitate solid structures. Liquid-filled balloons are used to simulate cystic structures. Adding stones can make the exercises more difficult due to hyperechoic reflexes with distal shadowing.
Results With the model, ultrasound-guided puncture and punch biopsies could be successfully simulated, and ultrasound images can be generated for this purpose. The cost of a single model is about 2 euros. Production takes less than 2 hours, including cooling. The pure processing time is 30 minutes. The durability of the models is limited by mold, which occurs after 5 days when stored at room temperature and after 5 weeks in the refrigerator.
Conclusion It was shown that it is possible to produce an inexpensive agar-agar-based ultrasound model in a short time and with easily available ingredients to learn ultrasound-guided puncture and punch biopsies.

AbstractA new method for the synthesis of N-alkoxy lactams and oximinolactones, involving the selective N-cyclization and O-cyclization of unsaturated N-alkoxy amides, is presented. This approach features mild reaction conditions and no requirement for transition-metal catalysts. The protocol demonstrates a wide range of applicability in 5-exo-trig and 6-exo-trig cyclization, accommodating chloro, bromo, and iodo electrophiles. The N-cyclization process can be achieved in the presence of strong lithium base such as LiHMDS or n-BuLi, while the O-cyclization occurs spontaneously without the addition of any base. Mechanistic studies reveal the N-cyclization reactions proceed through cyclic lithium intermediates, as confirmed by FT-IR studies and control experiments, which contribute to the N-selectivity. The current methodology was successfully used in synthesis of natural product (E/Z) des-hydroxy triticone A and B.
SFM Fetal Therapy Practice Guidelines: Radiofrequency Ablation of Fetal Umbilical Cord
Authors: Makam Adinarayan , Sharma Aparna , Bhatt Reema 
Published: March 2024

AbstractIn radiofrequency ablation (RFA), the ions in the tissue surrounding the probe's uninsulated tip are noticeably stirred up by the electrode's high-frequency alternating current. The surrounding tissue experiences thermal coagulation necrosis as a result of the frictional heat.RFA is used in complicated monochorionic twin pregnancies with selective fetal growth restriction (FGR), TRAP, and TTTS. RFA may also be considered in giant chorioangioma with favorable vascular anatomy and giant sacrococcygeal teratoma with imminent hydrops. It serves as a substitute to laser.
“Being useful, I think it's the result of a sick society”: Critical reflections on reproductive politics and markets by women freezing their eggs in Spain
Authors: Lafuente-Funes Sara 
Published: March 2024

AbstractThis piece analyzes the way in which women that froze, are considering freezing or are freezing their eggs in Spain think critically about broader reproductive politics in Spain and about assisted reproduction. Drawing partially on previous studies around egg freezing, Thomas Lemke has suggested that cryopreservation practices represent a “politics of suspension” characterized by both reversibility and disposition, and concomitant with broader political inaction (Lemke in Sci Technol Hum Values 48(4):1–27, 2021). Drawing on feminist literature, and on how some of these women think about motherhood, it is relevant to emphasize this ‘suspension of politics’ that takes place along with a “politics of suspension,” meaning that certain matters (such as reproduction and its postponement) are only to be dealt with privately and individually, through marketized fertility preservation programs in this case. Some of the women interviewed describe these programs as useful tools within a problematic context: technologies that give time in a context that leaves them on their own to figure out motherhood (or its absence) in the midst of uncertainty and loneliness. This paper shows their critical views on these matters, while reflecting on how their experiences and desires become increasingly imbricated with the fertility industry in the making of their reproductive biographies (Perler and Schurr in Body Soc 27(3): 3–27, 2021).
Cross-examination of photoinitiated carrier and structural dynamics of black phosphorus at elevated fluences
Authors: Chebl Mazhar , He Xing , Yang Ding-Shyue 
Published: March 2024

Revived attention in black phosphorus (bP) has been tremendous in the past decade. While many photoinitiated experiments have been conducted, a cross-examination of bP’s photocarrier and structural dynamics is still lacking. In this article, we provide such analysis by examining time-resolved data acquired using optical transient reflectivity and reflection ultrafast electron diffraction, two complementary methods under the same experimental conditions. At elevated excitation fluences, we find that more than 90% of the photoinjected carriers are annihilated within the first picosecond (ps) and transfer their energy to phonons in a nonthermal, anisotropic fashion. Electronically, the remaining carrier density around the band edges induces a significant interaction that leads to an interlayer lattice contraction in a few ps but soon diminishes as a result of the continuing loss of carriers. Structurally, phonon–phonon scattering redistributes the energy in the lattice and results in the generation of out-of-plane coherent acoustic phonons and thermal lattice expansion. Their onset times at ∼6 ps are found to be in good agreement. Later, a thermalized quasi-equilibrium state is reached following a period of about 40–50 ps. Hence, we propose a picture with five temporal regimes for bP’s photodynamics.
Convergent ab initio analysis of the multi-channel HOBr + H reaction
Authors: Beck Ian T. , Lahm Mitchell E. , Douberly Gary E. , Schaefer Henry F. 
Published: March 2024

High-level potential energy surfaces for three reactions of hypobromous acid with atomic hydrogen were computed at the CCSDTQ/CBS//CCSDT(Q)/complete basis set level of theory. Focal point analysis was utilized to extrapolate energies and gradients for energetics and optimizations, respectively. The H attack at Br and subsequent Br–O cleavage were found to proceed barrierlessly. The slightly submerged transition state lies −0.2 kcal mol−1 lower in energy than the reactants and produces OH and HBr. The two other studied reaction paths are the radical substitution to produce H2O and Br with a 4.0 kcal mol−1 barrier and the abstraction at hydrogen to produce BrO and H2 with an 11.2 kcal mol−1 barrier. The final product energies lie −37.2, −67.9, and −7.3 kcal mol−1 lower in energy than reactants, HOBr + H, for the sets of products OH + HBr, H2O + Br, and H2 + BrO, respectively. Additive corrections computed for the final energetics, particularly the zero-point vibrational energies and spin–orbit corrections, significantly impacted the final stationary point energies, with corrections up to 6.2 kcal mol−1.
Effets du feedback correctif écrit direct et indirect sur la réécriture du texte et les subséquentes
productions d’apprenants de l’italien LV3 au lycée

Résumé
Ce travail compare les effets du feedback correctif (FC) direct et indirect sur la réécriture du texte et les
subséquentes productions de 26 apprenants francophones de l’italien LV3. L’impact de leur engagement lors du
traitement du FC est également évalué. Les apprenants ont été répartis en trois groupes (feedback direct, feedback indirect et
groupe contrôle). Le protocole d’enquête a prévu un pré-test, une phase d’administration du FC, ainsi
qu’un post-test immédiat et différé. Les groupes expérimentaux obtiennent de meilleurs résultats par rapport au groupe
contrôle dans la réécriture du texte et dans les productions subséquentes. À un niveau d’engagement plus élevé lors du
traitement du FC correspondent de meilleurs résultats dans la réécriture du texte. Le FC indirect conduit les apprenants à
s’engager davantage dans le traitement, ce qui leur permet de corriger leurs erreurs dans la réécriture. Cet effort serait
atténué, dans le plus long terme, par le fait de ne pas savoir si leurs hypothèses de résolution sont correctes. Le FC direct, qui
donne de l’input en langue cible et la possibilité de le traiter immédiatement, porte les apprenants à améliorer davantage
la correction de leurs subséquentes productions.

Published: March 2024

Abstract
The connection of silicon carbide (SiC) to glass is important for the development of microelectromechanical systems. In the study, glass-SiC-glass with SiC as common anode was effectively bonded by using anodic bonding technology in atmosphere. The interfacial microstructure of bonded joints was analyzed by using scanning electron microscope, energy-dispersive spectrometer and transmission electron microscope. The effect of the bonding voltages and bonding temperatures on the interfacial microstructure and mechanical property of glass/SiC/glass was investigated. The results indicated that a Na+ depletion layer formed in the glass adjacent to the SiC/glass interface due to the decomposition of Na2O compound in the glass and the migration of Na+ towards the upper surface of glass during anodic bonding. With elevating bonding temperatures or bonding voltages, the thickness of Na+ depletion layer was gradually increased and more O2− accumulated at the SiC/depletion layer interface, which was beneficial for the tensile strength of joints. But owing to the increased residual thermal stress, the tensile strength of the joints dropped with enhanced bonding temperature. The maximum tensile strength of the joint was about ∼12.8 MPa when bonding at 450 °C/1000 V/1 min. The joint mainly ruptured in the glass with a brittle fracture mode.

Abstract
Electrochemical discharge machining is an advanced micro-machining process for machining of conductive as well as non-conductive hard and brittle materials, e.g. glass, ceramics, silicon wafer, etc. The present work explores the machining of glass using an in-house developed novel ultrasonic assisted rotary electrochemical discharge machining setup. The setup has specialized features, such as using ultrasonic vibrations to tool the electrode and incorporating rotary motion for manipulating the workpiece. Experiments were conducted using a one factor at a time approach by varying the tool feed rate, the amplitude of the vibrations and the rotation of the workpiece as process parameters. The quality of the machining output was evaluated by observing two key parameters: the overcut and the circularity of the hole. It was observed that as the workpiece rotation speed increased from 40 rpm to 60 rpm, the overcut in the machined samples decreased from 181.378 μm to 163.564 μm. The rotary motion of the workpiece caused a seeping action of the electrolyte in the hydrodynamic regime, leading to the formation of a thin gas film and the stabilization of the discharging process. The morphology of the machined hole exhibits better circularity, low heat-affected zones, minimum micro-cracks and smooth edges at its periphery due to stable discharge formation.

Published: March 2024

Abstract
This study used a microfluidic device with a focus-wrapping structure to create double-layer calcium alginate hydrogel drug particles in a one-step process. We validated the double-layer structure of the particles using both a fluorescence and regular light microscope. Curcumin and catalase were distributed independently in each layer, and we expected that such structure could play a role in the slow release of drugs. This scheme greatly reduces the need of hydrophilic and hydrophobic modification treatment, therefore greatly simplifies the experimental process. In the meantime, the requirement for injecting drugs into osteoarthritis and other diseases is expected to be realized, expanding the use of hydrogel in the medical field, because the microsphere is easy to generate, inexpensive, and strong in internal drug substitutability.

Abstract
High-quality monolithic Ge-on-Si is sought for CMOS-compatible optoelectronic devices. We examine the structural characteristics of Ge-on-Si grown by the aspect ratio trapping (ART) method on a SiO2/Si(001) template in pre-patterned holes. Transmission electron microscopy and surface topography analysis revealed high-quality Ge islands overgrown from the ART holes in SiO2. The superior crystal quality of Ge ART growth was also confirmed by comparing x-ray diffraction (XRD) data of Ge ART and Ge planar epilayer samples. The XRD and micro-Raman data additionally show a small residual strain in the islands which vanishes by reducing the hole diameter from 280 nm to 180 nm, while leading to only a minor increase in the crystallographic inclinations of the Ge islands from 0.34 deg to 0.54 deg. With finite element method simulations, we find that the small residual strain in Ge originates during the cool-down from growth to room temperature because of thermal expansion coefficient mismatch between Ge and SiO2. A tensile force develops along the [001] axis of the Ge pillar whose faster shrinkage to the room temperature volume is restricted by the oversized surface island.
A semi-supervised learning method based on pseudo-label iterative purification for intelligent fault diagnosis of rolling bearing
Authors: Yue Wenbo , Zhang Li , Yang Jianwei , Wang Dongpo 
Published: March 2024

Abstract
Bearing fault diagnosis based on semi-supervised learning shows good results in solving the scarcity of data in industrial scenarios. Pseudo-label samples can be used to expand labeled datasets, thereby to solve the shortage of training samples. However, when pseudo-labeling is employed to improve the performance of the model, the low confidence level of pseudo-labels will have a negative impact on the model. To solve this problem, the pseudo-label iterative purification method is proposed. Firstly, the graph neural network is employed to aggregate samples in order to increase the degree of dissimilarity among target domain data belonging to distinct categories. Subsequently, the pseudo-labeled samples are purified, while multiple positive-negative discriminators are trained on particular data from the source domain to accurately identify the target domain samples containing the pseudo-labels. Finally, the backbone network is fine-tuned by the purified pseudo-labeled samples. Results of experiments on the self-built bearing dataset and the Paderborn University bearing dataset validate that the method proposed in this article exhibits outstanding performance.
