Rating analysis and BERTopic modeling of consumer versus regulated mHealth app reviews in Germany
Authors: Uncovska Marie , Freitag Bettina , Meister Sven , Fehring Leonard 
Published: June 2023

AbstractGermany introduced prescription-based mobile health (mHealth) apps in October 2020, becoming the first country to offer them fully reimbursed by health insurance. These regulated apps, known as DiGAs, undergo a rigorous approval process similar to pharmaceuticals, including data protection measures and sometimes clinical trials. This study compares the user experience of DiGAs with non-prescription mHealth apps in Germany, analyzing both average app store ratings and written reviews. Our study pioneers the use of BERTopic for sentiment analysis and topic modeling in the mHealth research domain. The dataset comprises 15 DiGAs and 50 comparable apps, totaling 17,588 German-language reviews. Results reveal that DiGAs receive higher contemporary ratings than non-regulated apps (Android: 3.82 vs. 3.77; iOS: 3.78 vs. 3.53; p < 0.01; non-parametric Mann–Whitney–Wilcoxon test). Key factors contributing to positive user experience with DiGAs are customer service and personalization (15%) and ease of use (13%). However, challenges for DiGAs include software bugs (24%) and a cumbersome registration process (20%). Negative user reviews highlight concerns about therapy effectiveness (11%). Excessive pricing is the main concern for the non-regulated group (27%). Data privacy and security receive limited attention from users (DiGAs: 0.5%; comparators: 2%). In conclusion, DiGAs are generally perceived positively based on ratings and sentiment analysis of reviews. However, addressing pricing concerns in the non-regulated mHealth sector is crucial. Integrating user experience evaluation into the review process could improve adherence and health outcomes.

Authors: Iacono Roberta , De Lise Federica , Moracci Marco , Cobucci-Ponzano Beatrice , Strazzulli Andrea 
Published: June 2023

Abstract(Hyper)thermophilic archaeal glycosidases are enzymes that catalyze the hydrolysis of glycosidic bonds to break down complex sugars and polysaccharides at high temperatures. These enzymes have an unique structure that allows them to remain stable and functional in extreme environments such as hot springs and hydrothermal vents. This review provides an overview of the current knowledge and milestones on the structures and functions of (hyper)thermophilic archaeal glycosidases and their potential applications in various fields. In particular, this review focuses on the structural characteristics of these enzymes and how these features relate to their catalytic activity by discussing different types of (hyper)thermophilic archaeal glycosidases, including β-glucosidases, chitinase, cellulases and α-amylases, describing their molecular structures, active sites, and mechanisms of action, including their role in the hydrolysis of carbohydrates. By providing a comprehensive overview of (hyper)thermophilic archaeal glycosidases, this review aims to stimulate further research into these fascinating enzymes.
Speech Naturalness in the Assessment of Childhood Dysarthria
Authors: Schölderle Theresa , Haas Elisabet , Ziegler Wolfram 
Published: June 2023

Purpose:
This study investigated perceived speech naturalness estimated by adult listeners in typically developing children and children with dysarthria. We aimed to identify predictors of naturalness among auditory-perceptual parameters and to evaluate the concept of naturalness as a clinical marker of childhood dysarthria.

Method:
In a listening experiment, naive adult listeners rated speech naturalness of 144 typically developing children (3–9 years old) and 28 children with neurological conditions (5–9 years old) on a visual analog scale. Speech samples were recorded using the materials of the Bogenhausen Dysarthria Scales–Childhood Dysarthria, which also provides for auditory-perceptual judgments covering all speech subsystems.

Results:
Children with dysarthria obtained significantly lower naturalness ratings compared to typically developing children. However, there was a substantial age effect observable in the typically developing children; that is, younger typically developing children were also perceived as somewhat unnatural. The ratings of the typically developing children were influenced by the occurrence of developmental speech features; for the children with neurological conditions, specific symptoms of dysarthria had an additional effect. In both groups, the perception of naturalness was predominantly determined by the children's articulation and intelligibility.

Conclusions:
Both symptoms of childhood dysarthria and developmental speech features (e.g., regarding articulation and intelligibility) were associated to some extent with unnatural speech by the listeners. Thus, perceived speech naturalness appears less suitable as a marker of dysarthria in children than in adults.
Classroom Acoustics for Enhancing Students' Understanding When a Teacher Suffers From a Dysphonic Voice
Authors: Bottalico Pasquale , Murgia Silvia , Mekus Taylor , Flaherty Mary 
Published: June 2023

Purpose:
The purpose of this project is to assess the acoustical conditions in which optimal intelligibility and low listening difficulty can be achieved in real classrooms for elementary students, taking into consideration the effects of dysphonic voice and typical classroom noise.

Method:
Speech intelligibility tests were performed in six elementary classrooms with 80 normal-hearing students aged 7–11 years. The speech material was produced by a female actor using a normal voice quality and simulating a dysphonic voice. The stimuli were played by a Head and Torso Simulator. Child babble noise and classrooms with different reverberation times were used to obtain a Speech Transmission Index (STI) range from 0.2 to 0.7, corresponding to the categories bad, poor, fair, and good.

Results:
The results showed a statistically significant decrease in intelligibility when the speaker was dysphonic, in STI higher than 0.33. The rating of listening difficulty showed a significantly greater difficulty in perceiving the dysphonic voice. In addition, younger children showed poorer performance and greater listening difficulty compared with older children when listening to the normal voice quality. Both groups were equally impacted when the voice was dysphonic.

Conclusions:
The results suggested that better acoustic conditions are needed for children to reach a good level of intelligibility and to reduce listening difficulty if the teacher is suffering from voice problems. This was true for children regardless of grade level, highlighting the importance of ensuring more favorable acoustic conditions for children throughout all elementary schools.

Underwater image enhancement via a channel‐wise transmission estimation network
Authors: Wang Qiang , Fu Bo , Fan Huijie 
Published: June 2023

AbstractUnderwater image enhancement for image processing and underwater robotic vision have recently attracted much academic attention. However, in most existing methods, underwater image enhancement is completed with a simple assumption: the attenuation coefficients are unified across the color channels. This assumption leads to unstable and visually unpleasing enhancement results. Moreover, these methods cannot be successfully applied to explore relatively independent transmissions from multiple color channels with complimentary feature information. To address these challenges, a novel channel‐wise transmission estimation network (CTEN) is proposed, which aims to pioneer the exploration of the transmission difference across the color channels in an underwater scene. Specifically, a color‐specific correction module is proposed to automatically quantify the transmission ability of multiple color channels in the underwater environment. Furthermore, a channel‐wise transmission estimation module is designed to simultaneously explore the relative independence of multi‐color channels and estimate the medium transmissions for each color channel, which represents the attenuation degree of different color radiances after reflecting in the water. Then, a novel residual strategy is introduced to integrate these two modules to complete the underwater enhancement. Using the model, the authors are able to provide an answer as to why channel‐wise transmission estimation are better than single transmission estimation and establish a generalization theory to show the effect of the independent transmission estimation model for each color channel. Experiments on several underwater image datasets verify the superiority of the proposed CTEN model.
Massage bei Rheuma
Authors: Best Norman 
Published: June 2023

ZUSAMMENFASSUNGKomplexe Erkrankungen, wie die des rheumatischen Formenkreises, bedürfen in der Regel auch komplexer Therapieprogramme. In diesem Fall besteht die Möglichkeit, neben den in den letzten Jahren deutlich verbesserten medikamentösen Therapieoptionen, auch nichtmedikamentöse Anwendungen in das Therapieregime zu integrieren. Massagetherapien gelten gemeinhin als angenehme Maßnahmen, wenn nicht gar Wellnessanwendungen. Dies ist nur zum Teil richtig, denn die korrekterweise medizinischen Massagen genannten Therapiekonzepte sind in der Regel nicht mit Wellnessanwendungen zu vergleichen. Nachweisen lassen sich für Patientinnen und Patienten mit rheumatoider Arthritis positive Effekte hinsichtlich Schmerz, Lebensqualität und Gewebebeschaffenheit. Zu empfehlen sind klassische Massagen und Bindegewebsmassagen. Die Kontraindikationen sind nicht immer klar definiert. Auch jenseits der derzeit üblichen Einsatzbeschränkungen sind im Einzelfall Anwendungen möglich. Symptomzentrierte und individuelle Therapieanwendungen sind Grundvoraussetzung für eine erfolgreiche Anwendung von Massageformen, oft in Kombination mit medikamentösen Therapien.

Ultraschalluntersuchungen in der Kinderrheumatologie
Authors: Windschall Daniel , Roth Johannes 
Published: June 2023

ZUSAMMENFASSUNGInsbesondere in der komplexen anatomischen Region eines kindlichen Sprunggelenkes und Fußes profitieren Sicherheit und Genauigkeit bei der Diagnosestellung einer rheumatischen Entzündung vom Ultraschall in Ergänzung zum klinischen Befund. Mehrere Studien der letzten Jahre konnten für diese Region die Überlegenheit des Ultraschalls gegenüber der klinischen Untersuchung nachweisen. Mit zunehmendem Einsatz des Gelenkultraschalls verbessern sich die diagnostischen Möglichkeiten bei der Diagnosestellung, Abgrenzung und im Verlaufsmonitoring kindlich rheumatischer Erkrankungen. So können entzündliche Gelenkveränderungen und Sehnenbeteiligungen hervorragend differenziert und im Verlauf kontrolliert werden. Neben den typischen sonografischen Zeichen einer Gelenkentzündung lassen sich im Bereich der Sprunggelenke und Füße auch rheumatische Sehnenscheidenentzündungen, Sehnenansatzentzündungen und Schleimbeutelentzündungen sicher nachweisen. Wichtige Differenzialdiagnosen können sonografisch ausgeschlosssen oder bestätigt werden. Die zunehmende Standardisierung erhöht die Zuverlässigkeit dieser bedienerabhängigen Bildgebungstechnik und hilft bei der praktischen Durchführung, Beurteilung und Quantifizierung der pathologischen Befunde.
Pharmakovigilanz in der integrativen Onkologie
Authors: Stoll Günther 
Published: June 2023

ZusammenfassungFür die Bewertung einer Therapiemethode oder eines Arzneimittels spielen
die Wirksamkeit und die Frage nach Nebenwirkungen, deren Häufigkeit und
Schweregrad, also das Sicherheitsprofil, eine herausragende Rolle. Dies gilt
ganz besonders für die integrative Onkologie, da beim Tumorpatienten
ohnehin schon viele verschiedene Wirksubstanzen parallel zur Anwendung kommen
und jede zusätzliche Substanz oder gar ein phytotherapeutischer Extrakt
mit einer Vielzahl von Komponenten die Gefahr von Wechselwirkungen oder
zusätzlichen Nebenwirkungen erhöht. In diesem ersten Beitrag zur
Pharmakovigilanz in der komplementären Therapie sollen zunächst
einige Grundbegriffe der Arzneimittelsicherheit besprochen und die Situation der
Phytopharmaka beleuchtet werden, in einem Folgebeitrag werden dann Vitamine und
vor allem Spurenelemente in dieser Hinsicht untersucht. Neben der generellen
Gefahr des „Underreporting“ ist die Situation bei
Phytotherapeutika insgesamt unbefriedigend.
Praseodymium-dopant effect on bismuth-substituted yttrium iron garnet films on fused silica glass substrate at the 1310 and 1550-nm wavelengths
Authors: Kim Seung Hwan , Park Beomsu , Park Ji Woon , Oh Seunghyun , Oh Kwanglim , Ryu Han-Youl , Kim Kyong Hon 
Published: June 2023

The optical and magneto-optic (MO) properties of the praseodymium (Pr)-dopant effect on bismuth-substituted yttrium iron garnet (Bi:YIG) films coated on fused silica glass substrates by using the metal-organic-decomposition (MOD) method with chemical solutions were investigated at the 1310 and 1550-nm wavelength regions. The maximum Faraday rotation angle of the Pr-codoped Bi:YIG (Pr,By:YIG) film was observed to be 0.09 and 0.046 deg/μm at the wavelengths of 1310 and 1550 nm, respectively, when the film was annealed at a temperature of 750 °C, while those of the plain Bi:YIG film were 0.059 and 0.039 deg/μm. More than 50% improvement in the Faraday rotation value of the Pr,Bi:YIG film was observed compared to that of the Bi:YIG film at the 1310 nm wavelength. The absorption coefficient of the Pr,Bi:YIG film was comparable to that of the Bi:YIG film. Therefore, the Pr,Bi:YIG film prepared with the MOD method is potentially useful for MO applications such as optical isolators and circulators.
Innovative analytical approach to estimate side-hole type parallelepiped sodium iodide scintillation detector efficiencies
Authors: Alzahrani Jamila S. , El-Khatib Ahmed M. , Abbas Mahmoud I. 
Published: June 2023

The geometric and absolute total detection efficacies of a parallelepiped sodium iodide (with a cylindrical side-hole) detector were calculated and compared to the simulated Monte Carlo and experimental data described in the literature. This new-shaped detector is characteristically meant to be employed for low-level radioactive specimens in γ-ray-spectroscopy and nuclear reactions because of its extraordinarily high γ-ray-efficiency. An innovative systematic theoretical method is used herein to calculate the efficiency of a cylindrical side-hole (left empty for isotropic radiating sample access)-type parallelepiped (A × B × C) sodium iodide scintillation detector. The contrast of the geometric (εg) and absolute total detection (ε) efficacies for point-specimen-geometry at numerous specimen-to-detector distances (h) and in the energy range of 0.511–1.332 MeV showed that method reported by us is beneficial in the efficiency evaluation of side-hole-type parallelepiped scintillation detectors.
A historical monthly upper-air humidity dataset for Australia
Authors: Jovanovic Branislava , Smalley Robert , Siems Steven 
Published: June 2023

Monthly humidity (represented as dew point temperature, DWPT) data from 22 land and 5 island Australian upper-air sites were analysed, with trends estimated over the 1965–2017 period at four pressure levels. Humidity data were selected to ensure that data collected under consistent sampling conditions were used (‘modified data’). The quality control process involved examining station metadata and applying an objective statistical test that detected discontinuities in the data series. At each station and pressure level, modified data series were adjusted (homogenised) on a monthly timescale when discontinuities were identified. Analysis of the homogenised (adjusted) modified DWPT data indicates that, over the 1965–2017 period, linear trends are mostly positive and smaller compared to unadjusted modified data. The all-Australian time-series show positive trends at the 850–400-hPa levels. The total increases in DWPT since 1965 at 850-, 700-, 500- and 400-hPa levels are ~0.5, ~1.2, ~1.3 and ~0.8°C respectively. The increase in humidity in the lower and middle troposphere is in accordance with the expectation that, as the troposphere warms, the amount of moisture in it should increase (at a differential rate of ~7% °C–1 at low altitudes globally, following Clausius–Clapeyron scaling) due to increasing surface evaporation and moisture-holding capacity of the air. However, changes in atmospheric dynamics also influence the magnitude and distribution of humidity trends. The homogenised modified Australian radiosonde data for the 850-hPa level show that the amount of moisture at this level increased ~8.8% °C–1 during 1965–2015

Testing of a new type SEU-tolerant SRAM
Authors: Song Chunxiao , Qin Jiajun , Chang Zeguang , Guo Jiacheng , Zhao Lei 
Published: June 2023

Abstract
In high-energy physics experiments, it is a trend to implement digitalization in the front end of readout electronics based on Application Specific Integrated Circuits (ASICs), which are exposed to the radiation environment. As an important part of ASIC, SRAM (Static Random-Access Memory) is impressionable to Single Event Upset (SEU) due to the radiation environment. Therefore, a new SEU-tolerant SRAM cell structure was designed in our previous work. In this paper, a test system for evaluating the radiation tolerance effect of this SRAM structure is described, and the chip’s performance in the radiation environment is presented. The test results show that the new SRAM cell upset cross-section was reduced by five times compared with the ordinary 6T cell without increasing the power consumption.
A non-destructive method for fixing placards with masonry structures
Authors: Bianco L , Bianco A 
Published: June 2023

Abstract
It is common practice for government agencies to fix signs – and indeed even official temporary notices – onto masonry structures using steel nails. This method of fixing is destructive; it causes irreversible damage to the material fabric, which has a bearing on the overall aesthetic of the building, a scenario which is more acute if the site is of cultural heritage significance. Stones and concrete blocks (locally referred to as concrete bricks), the latter introduced in the 1950s, are the main materials used in masonry construction in Malta. Clay bricks are not utilized, as in Malta there is a blanket prohibition on the extraction of local clay. The main building material used in Malta since time immemorial is Lower Globigerina Limestone. This article puts forward the case for a non-destructive, reversable method to fix notices to building which respects the integrity of the dimension stones. Instead of being hammered into masonry blocks, the proposed removable plugs are installed in the mortar. Their size is relative to the thickness of the mortar bed and the load they are designed to carry, the latter being of negligible importance in the case of lightweight placards. The proposed solution applies equally to other masonry structures, whether erected in dimension or randomly placed stones, concrete blocks or clay bricks, as long as the construction in question uses mortar in the joints between the units.
Studies on heavy duty pavements reinforced with steel fibers for port infrastructures
Authors: Ionițoaiei P , Rotaru A 
Published: June 2023

Abstract
Steel fiber reinforced concrete (SFRC) for industrial floors has become a state-of-the-art construction method in all industries worldwide, including the construction of port platforms. The first patent that refers to a dispersed reinforced concrete element with steel fibers there exists since 1874 and was patented in the USA (California) by A. Bernard who proved the improvement of the strength of the concrete by adding some uneven steel scraps. Steel fibers have been created to improve the durability and flexibility of concrete under high loads, over long periods of time, providing three-dimensional reinforcement of concrete. Steel fibers can be used as the sole form of reinforcement or in combination with reinforcement bars or welded wire mesh.
