The Impact of Executive Functions and Musicality on Speech Auditory-Motor Synchronization in Adults Who Stutter
Authors: Zhu Min , Chen Fei , Chen Weiping , Zhang Yang 
Published: December 2024

Purpose:
Stuttering is a neurodevelopmental disorder that disrupts the timing and rhythmic flow of speech production. There is growing evidence indicating that abnormal interactions between the auditory and motor cortices contribute to the development of stuttering. The present study investigated speech auditory-motor synchronization in stuttering adults and the influential factors behind it as compared to individuals without stuttering.

Method:
Sixteen Mandarin-speaking adults with stuttering and 19 fluent controls, who were matched for age, gender, and years of musical training, participated in the current study. Their ability to synchronize vocal speech production with accelerating auditory sequences was assessed using the spontaneous speech-to-speech synchronization test (SSS test). Additionally, all participants conducted a series of standardized behavioral tests to evaluate their musicality and executive functions.

Results:
Stutterers achieved significantly lower phase locking values in the SSS test compared to nonstuttering controls, indicating a potential rhythmic processing deficit in developmental stuttering. Moreover, the strength of speech auditory-motor synchronization in stutterers was significantly associated with their performance in tasks such as digit span and nonword repetition. This finding further emphasizes the strong link between rhythmic processing and working memory.

Conclusions:
This study provides compelling evidence for the speech rhythmic deficit in individuals with stuttering by incorporating auditory-motor processes. It would offer valuable insights into the intricate relationship between language and the brain and shed light on the potential benefits of cognitive training for speech intervention in individuals with stuttering difficulties.

Generalization of Interarticulator Timing Control: Evidence From Tongue–Jaw and Lip–Jaw Kinematics Using Electromagnetic Articulography
Authors: Masapollo Matthew , Rodriguez Ana , Gendron Rosalie , Kent Kara , Thomas Hannah , Nittrouer Susan 
Published: December 2024

Background:
In skilled speech production, the motor system coordinates the movements of distinct sets of articulators to form precise and consistent constrictions in the vocal tract at distinct locations, across contextual variations in movement rate and amplitude. Research efforts have sought to uncover the critical control parameters governing interarticulator coordination during constriction formation, with a focus on two parameters: (a) latency of movement onset of one articulator relative to another (temporal parameters) and (b) phase angle of movement onset for one articulator relative to another (spatiotemporal parameters). Consistent interarticulator timing between jaw and tongue tip movements, during the formation of constrictions at the alveolar ridge, was previously found to scale more reliably than phase angles across variation in production rate and syllable stress. In the present study, we test whether these temporal regularities generalize to another set of articulators, namely, the jaw and lower lip, during the formation of constrictions at the lips.

Method:
Eight talkers produced vowel–consonant–vowel (VCV) sequences, recorded using electromagnetic articulography, with variation in production rate and syllable stress. V was /ɑ/–/ɛ/ and C was alveolar /t/–/d/ or bilabial /p/–/b/. Two measures were obtained: (a) the timing of tongue tip/lower lip raising onset for intervocalic C, relative to jaw opening–closing cycles for the flanking vowels, and (b) the angle of tongue tip/lower lip raising onset for intervocalic C, relative to the jaw phase plane.

Results:
Across both sets of articulators, consonant-related movement onset latencies scaled more consistently with variation in the jaw opening–closing cycle than phase angles. Furthermore, movement onset latencies were more strongly affiliated with utterance type than phase angles.

Conclusion:
Findings demonstrate that precise temporal coordination of articulator movements regulates the formation of precise constrictions, independent of the specific set of articulators involved or where in the vocal tract the constriction is produced.
Approach for identifying crop seeds with similar appearances using hyperspectral images and improved ResNet 18 based on cloud platform
Authors: Li Hui , Duan Xuliang 
Published: December 2024

AbstractThis study proposes an improved ResNet18 model based on cloud platform and hyperspectral image to identify crop seeds. Hyperspectral images are preprocessed by moving average method (MA) and standard normal variable transformation (SNV) to reduce spectral data interference. The successive projection algorithm (SPA) is used to select characteristic wavelengths and reduce the band dimension. The heterogeneous convolution and channel attention mechanism (CAM) are used to reduce parameters and computation load of ResNet18. Image recognition with improved ResNet18 takes 4.4 s with 4.2 s improvement over the original ResNet18 and saves 2808 KB memory. Accuracy has increased from 93.1% to 96.7%. The improved ResNet18 was deployed on Alibaba Cloud ESC server with uWSGI, Nginx and flask to achieve high concurrency and fast recognition. For single‐variety seed identification, the average time reduced to 0.56 s, with an 87% decrease and accuracy is 96.3%. For mixed seeds of five types, accuracy is 90.22% with a time consumption of 0.88 s. The results demonstrated that the proposed method exhibited high effectiveness and accuracy.
Few‐shot real scenes convolutional anchor clustering twin network for hyperspectral image classification
Authors: Zhou Xiangshan , Tong Xiaoyi , Zhou Xuchuan , Wang Lin , Zhang Lei , Zhou Jie , Qin Su 
Published: December 2024

AbstractIn order to improve the performance of hyperspectral open set recognition processing with insufficient sample size, the authors propose a new supervised contrastive learning (SCL) framework (FSSCL‐OSC) that can achieve open‐set classification of hyperspectral images in scenarios with very few sample sizes, which consists of three steps. First, supervised contrastive learning (SCL) with geometric transformations is designed, which uses rotated labels as supervision to obtain lower‐level characteristics that more accurately capture various orientations and then makes use of a spectral‐spatial characteristic extraction network to maximize the utilization of HSI's spectrum and spatial information. Next, a class anchor open‐set classification module based on a twin clustering network is designed, which uses SCL and FSL to extract more specific personal information by mining the category‐invariant characteristics present in the known versus unknown class data. Finally, multiple convolution and open‐set recognition (OSC) is performed on the feature blocks. Experimental results on three classical HSI datasets show that FSSCL‐OSC provides a significant improvement over existing methods, under a sample size of only 10%, the overall accuracy reached 82.38%, 90.76% and 84.70%, respectively.
The long‐term influence of wind and temperature on performance and degradation within an utility‐scale photovoltaic plant
Authors: Daniel‐Durandt Francisca Muriel , Rix Arnold Johan 
Published: December 2024

AbstractAn inverter‐level analysis of a large photovoltaic (PV) plant is evaluated over four years to investigate the long‐term performance and degradation caused by wind and temperature effects. The multi‐megawatt utility‐scale PV plant is located in a semi‐arid region in South Africa. The degradation rate is determined using the performance ratio as a comparison metric between the different inverters. The degradation from the first year of operation up to the fourth year shows that different areas of the PV plant have varying degradation rates. The spatial degradation analysis indicates that inverter blocks operating at higher ambient temperatures and lower wind frequency measurements show higher rates of degradation compared to inverter groups operating at lower temperatures and higher wind frequency. Notably, the lowest degradation rates correlate positively with wind direction and frequency from the North and North‐East, indicative of a cooling influence on the PV modules. The weather‐corrected performance analysis indicates that the most prominent wind direction (North) has the highest mean performance ratio, further supporting the claims that the cooling effect of wind improves performance and efficiency. The widening gap between the best‐ and worst‐performing inverters annually underscores the premise that specific inverters' PV modules degrade at disparate rates within the PV plant. The results of this work present future designs of PV plants that could potentially be optimised to take advantage of wind as a cooling tool, which may further enhance the longevity and sustainability of large PV installations.
Detection of stellar wakes in the Milky Way: A deep learning approach
Authors: Põder Sven , Pata Joosep , Benito María , Alonso Asensio Isaac , Dalla Vecchia Claudio 
Published: December 2024

Context. Due to poor observational constraints on the low-mass end of the subhalo mass function, the detection of dark matter (DM) subhalos on sub-galactic scales would provide valuable information about the nature of DM. Stellar wakes, induced by passing DM subhalos, encode information about the mass (properties) of the inducing perturber and thus serve as an indirect probe for the DM substructure within the Milky Way.
Aims. Our aim is to assess the viability and performance of deep learning searches for stellar wakes in the Galactic stellar halo caused by DM subhalos of varying mass.
Methods. We simulated massive objects (subhalos) moving through a homogeneous medium of DM and star particles with phase-space parameters tailored to replicate the conditions of the Galaxy at a specific distance from the Galactic centre. The simulation data was used to train deep neural networks with the purpose of inferring both the presence and mass of the moving perturber. We then investigated the performance of our deep learning models and identified the limitations of our current approach.
Results. We present an approach that allows for quantitative assessment of subhalo detectability in varying conditions of the Galactic stellar and DM halos. We find that our binary classifier is able to infer the presence of subhalos in our generated mock datasets, showing non-trivial performance down to a mass of 5 × 107 M⊙. In a multiple-hypothesis case, we are also able to discern between samples containing subhalos of different mass. By simulating datasets describing subhalo orbits at different Galactocentric distances, we tested the robustness of our binary classification model and found that it performs well with data generated from different initial physical conditions. Based on the phase-space observables available to us, we conclude that overdensity and velocity divergence are the most important features for subhalo detection performance.
Interaction between the supernova remnant W44 and the infrared dark cloud G034.77-00.55: Shock induced star formation

Published: December 2024

Context. We have studied the dense gas morphology and kinematics towards the infrared dark cloud (IRDC) G034.77-00.55, shock-interacting with the SNR W44, to identify evidence of early-stage star formation induced by the shock.
Aims. We used high angular resolution N2H+(1−0) images across G034.77-00.55, obtained with the Atacama Large Millimeter/sub-Millimeter Array. N2H+ is a well-known tracer of dense and cold material, optimal for identifying gas that has the highest potential to harbour star formation.
Methods. The N2H+ emission is distributed in two elongated structures, one towards the dense ridge at the edge of the source and one towards the inner cloud. Both elongations are spatially associated with well-defined mass-surface density features. The velocities of the gas in the two structures (i.e. 38–41 km s−1 and 41–43 km s−1) are consistent with the lowest velocities of the J- and C-type parts, respectively, of the SNR-driven shock. A third velocity component is present at 43–45.5 km s–1. The dense gas shows a fragmented morphology with core-like fragments at scales consistent with the Jeans lengths, masses of ~1–20 M⊙, densities of (n(H2)≥105 cm–3) sufficient to host star formation in free-fall timescales (a few 104 yr), and with virial parameters that suggest a possible collapse.
Results. The W44 driven shock may have swept up the encountered material, which is now seen as a dense ridge, almost detached from the main cloud, and an elongation within the inner cloud, well constrained in both N2H+ emission and mass surface density. This shock compressed material may have then fragmented into cores that are either in a starless or pre-stellar stage. Additional observations are needed to confirm this scenario and the nature of the cores.
Stabilization of control systems associated with a strongly continuous group
Authors: Nguyen Hoai-Minh 
Published: December 2024

This paper is devoted to the stabilization of a linear control system $y' = A y + B u$ and its suitable non-linear variants where $(A, \cD(A))$ is an infinitesimal generator of a strongly continuous {\it group} in a Hilbert space $\mH$, and $B$ defined in a Hilbert space $\mU$ is an admissible control operator with respect to the semigroup generated by $A$. Let $\lambda \in \mR$ and assume that, for some {\it positive} symmetric, invertible $Q = Q(\lambda) \in \cL(\mH)$, for some {\it non-negative}, symmetric $R = R(\lambda) \in \cL(\mH)$, and for some {\it non-negative}, symmetric $W = W(\lambda) \in \cL(\mU)$, it holds
[[EQUATION]]
We then present a new approach to study the stabilization of such a system and its suitable nonlinear variants. Both the stabilization using dynamic feedback controls and the stabilization using static feedback controls in a weak sense are investigated. To our knowledge, the nonlinear case is out of reach previously when $B$ is unbounded for both types of stabilization.

Published: December 2024

Abstract
Purpose  To detect sonographic abnormalities of the supratentorial
structures of the brain – future cavum septum pellucidum, cavum velum
interpositum, third ventricle, ganglionic eminence and thalamus/hypothalamus –
in fetuses with a crown-rump length of 45–84 mm in high-risk pregnancies.
Materials and Methods  This study presents the retrospective analysis of
transvaginally recorded 3D volumes of the fetal brain of 64 fetuses whose
mothers consulted our ambulatory department for fetomaternal medicine for
organic and/or genetic changes of their fetuses at GW 12–14. For this study we
selected fetuses with 3D volume blocks of the fetal brain at best sonographic
quality enabling detailed analysis and measurement of the supratentorial brain
structures to correlate the results with the results of genetic analysis,
ultrasound controls in later weeks of pregnancy, and fetal outcome.
Results  Of 44 fetuses with genetic changes and 20 fetuses with syndromic
changes, structural brain changes were found in 27 fetuses, analyzed by
correlating the brain structures with the recently published structures of the
brain at gestational week 12-14 in early pregnancy, presenting new details of
early pathological brain development – migration disorders, milder variants of
holoprosencephaly (lobar, MIH), corpus callosum agenesis, for the first time in
early pregnancy.
Conclusion  Supratentorial defects of the brain can be detected and
analyzed in GW 12–14 in detail by direct analysis of sonopathology and
visualization of pathological measurements using transvaginal 3D sonography in
high quality.
SGLT-2-Inhibitoren – Eine Standortbestimmung in der deutschen oralen Therapielandschaft für Menschen mit Typ-2-Diabetes
Authors: Aberle Jens , Blüher Matthias , Laudes Matthias , Merkel Martin , Sandow Petra 
Published: December 2024

ZusammenfassungWie aus zahlreichen umfangreichen Studien hervorgeht, haben SGLT-2-Inhibitoren nicht nur positive Effekte auf den Glukosestoffwechsel, sondern darüber hinaus eine ausgeprägte protektive Wirkung auf Herz und Nieren. Damit kommt dieser Wirkstoffklasse eine wichtige Rolle in der Primär- und Sekundärprävention diabetes-assoziierter Komorbiditäten zu. Leitlinien sprechen auf Basis der Evidenz für SGLT-2-Inhibitoren eine Empfehlung für deren frühen Einsatz bei Menschen mit Typ-2-Diabetes und gleichzeitigem hohen Risiko für kardiovaskuläre und/oder renale Ereignisse aus. Verordnungszahlen zeigen jedoch, dass diese Empfehlungen aktuell nicht umgesetzt werden und deutlich mehr Menschen mit Typ-2-Diabetes von einer organprotektiven Therapie profitieren könnten. Daher soll in dieser Übersichtsarbeit der Stellenwert der SGLT-2-Inhibitoren im Vergleich zu anderen oralen Therapieansätzen für die Behandlung des Typ-2-Diabetes dargestellt werden.

Zusammenfassung
Ziele der Studie Die Studie gewährt Einblicke in die suchttherapeutischen
Konzepte der Kliniken von Hugo von Keyserlingk in Schwerin und Hubertus
Windischmann in Brandenburg und ermöglicht ein Verständnis der spezifischen
Problemlagen in diesem Teilbereich der psychiatrischen Versorgung in der DDR.
Methodik Vornehmlich in der DDR selbst publizierte Arbeiten werden
eruiert, analysiert und kontextualisiert. Die Experteninterviews mit zwei
führenden Suchttherapeuten der DDR, von Keyserlingk und Windischmann, ergänzen
und vertiefen die schriftlichen Quellen.
Ergebnisse Anfänglich noch mangelhafte Ansätze zur Alkoholkrankentherapie
nach dem Zweiten Weltkrieg entwickelten sich allmählich zu komplexeren und auch
verschiedenartigen Strukturen. So entstand ab den 1960er-Jahren unter von
Keyserlingk eine Suchtklinik, während Windischmann ein Suchtkrankendispensaire
mit verschiedenen Therapieoptionen etablierte.
Schlussfolgerungen Die Beiträge von Keyserlingks und Windischmanns spielen
eine bedeutende Rolle bei der Entwicklung von Therapiekonzepten. Es wird durch
die Studie deutlich, dass sie für die Alkoholkrankenfürsorge in der DDR
Pionierfunktion hatten.
Selective Bilateral Posterior Canal Dysfunction: A Case Series Investigation into the Clinical Trends and Associative Factors
Authors: Behr Evalena R. , Honaker Julie A. 
Published: December 2024

Abstract
Background The video head impulse test measures high-frequency vestibulo-ocular function of all six semicircular canals. Isolated semicircular canal dysfunction has been correlated with several peripheral and central vestibular etiologies. Selective bilateral posterior canal dysfunction is a trend seen in the clinical setting but less commonly reported in the medical literature.
Purpose The purpose of this work is to explore the clinical profile of bilateral posterior canal dysfunction along with other presenting factors such as hearing loss, increased age, and associated nystagmus patterns.
Method A case series of three patients (age range: 67–74 years) is presented to illustrate the similarities and clinical associations between vestibular and balance history, medical history, and vestibular test results.
Results All three patient cases presented with below reference range posterior semicircular canal function on video head impulse testing. Two patients also presented with down-beating nystagmus, and two endorsed subjective hearing loss while the third presented with presbycusis.
Conclusion Selective bilateral posterior canal dysfunction in association with advanced age, presbycusis, and signs of down-beating nystagmus may be associated with vestibulocochlear degenerative processes. Yet, central disorders, technical and patient factors may present clinical challenges to elucidate the cause.

Published: December 2024

AbstractAutistic adults report communication access barriers related to the prioritization of speech over all other forms of communication. Our participatory research team, including autistic adults who use augmentative and alternative communication (AAC) both part- and full-time, designed and administered a 35-question online survey to examine school-based professionals' knowledge, training, and practices related to AAC and autism. The current study reports a portion of the larger data set specific to participants' definitions of speech terms related to autistic speech. A total of 567 participants completed the survey. Thematic analysis of participants' responses to speech definitions revealed multiple themes, including a focus on speech without implying or suggesting other forms of communication, speech production (mechanics), communication functions (intentionality), deficits, and definitions that were exclusionary in nature (e.g., identifying what the term did not define). Quantitative analysis of definitions of autistic speech revealed the need for increased exposure to these internal speech states for professionals working with autistic children. Increasing school-based professionals' knowledge, including community-sourced knowledge, related to autism and AAC, can improve access to AAC for speaking autistic students who may benefit from AAC.

Published: December 2024

AbstractGastric teratomas are an extremely rare variety of teratomas in children. The aim of our series is to present the natural history and progression of the disease. Retrospective analysis of prospectively maintained data of all the gastric teratoma patients treated at our center was done from their electronic medical records. A total of four cases of gastric teratoma were found to have been treated, all of them being less than 1 year old with three-fourths being male. Typical imaging features of teratoma along with normal germ cell tumor markers helped in making a diagnosis. Surgery is the main form of treatment. In final histopathology, there was equal distribution of mature and immature teratomas. On long-term follow-up, there has been no incidence of recurrence. There needs to be reporting of more cases to verify its natural history.
