Electroencephalographic Classification Reveals Atypical Speech Motor Planning in Stuttering Adults
Authors: Kinahan Sean P. , Saidi Pouria , Daliri Ayoub , Liss Julie , Berisha Visar
Published: June 2024

Purpose:

This study explores speech motor planning in adults who stutter (AWS) and adults who do not stutter (ANS) by applying machine learning algorithms to electroencephalographic (EEG) signals. In this study, we developed a technique to holistically examine neural activity differences in speaking and silent reading conditions across the entire cortical surface. This approach allows us to test the hypothesis that AWS will exhibit lower separability of the speech motor planning condition.

Method:

We used the silent reading condition as a control condition to isolate speech motor planning activity. We classified EEG signals from AWS and ANS individuals into speaking and silent reading categories using kernel support vector machines. We used relative complexities of the learned classifiers to compare speech motor planning discernibility for both classes.

Results:

AWS group classifiers require a more complex decision boundary to separate speech motor planning and silent reading classes.

Conclusions:

These findings indicate that the EEG signals associated with speech motor planning are less discernible in AWS, which may result from altered neuronal dynamics in AWS. Our results support the hypothesis that AWS exhibit lower inherent separability of the silent reading and speech motor planning conditions. Further investigation may identify and compare the features leveraged for speech motor classification in AWS and ANS. These observations may have clinical value for developing novel speech therapies or assistive devices for AWS.

Authors: Weatherill Maryanne , Tibus Elizabeth O. , Rodriguez Amy D.
Published: June 2024

Purpose:

This article describes the use of the Virtual-Appropriate Decision Approach (VADA). VADA is a systematic data gathering and problem-solving approach for planning and troubleshooting human, setting, and technology-related issues that may arise when conducting aphasia assessments via telepractice. Case examples are provided to illustrate and discuss its application for clinical and research settings.

Method:

We describe how VADA was used to analyze and mitigate challenges during administration of aphasia assessments in five (four cisgender males, one cisgender female) research participants via telepractice. Case discussions are organized by aphasia types and identify a variety of human, setting, and technology-related issues, which are analyzed via the VADA framework. Successes, challenges, and recommendations for conducting aphasia assessment via telepractice are included for each case.

Conclusions:

Unique challenges exist when using telepractice to conduct clinically valid standardized aphasia assessments for research or in the clinic. VADA is a systematic process to gather, analyze, evaluate, and address human, setting, and technology factors that impact aphasia assessments conducted via telepractice. The use of aphasia-friendly printed materials, assistance from communication partners, and similar task practice were adaptations that helped facilitate the assessment process.
A lightweight underwater fish image semantic segmentation model based on U‐Net
Authors: Zhang Zhenkai , Li Wanghua , Seet Boon‐Chong
Published: June 2024

Semantic segmentation of underwater fish images is vital for monitoring fish stocks, assessing marine resources, and sustaining fisheries. To tackle challenges such as low segmentation accuracy, inadequate real‐time performance, and imprecise location segmentation in current methods, a novel lightweight U‐Net model is proposed. The proposed model acquires more segmentation details by applying a multiple‐input approach at the first four encoder levels. To achieve both lightweight and high accuracy, a multi‐scale residual structure (MRS) module is proposed to reduce parameters and compensate for the accuracy loss caused by the reduction of channels. To improve segmentation accuracy, a multi‐scale skip connection (MSC) structure is further proposed, and the convolution block attention mechanism (CBAM) is introduced at the end of each decoder level for weight adjustment. Experimental results demonstrate a notable reduction in model volume, parameters, and floating‐point operations by 94.20%, 94.39%, and 51.52% respectively, compared to the original model. The proposed model achieves a high mean intersection over union (mIOU) of 94.44%, mean pixel accuracy (mPA) of 97.03%, and a frame rate of 43.62 frames per second (FPS). With its high precision and minimal parameters, the model strikes a balance between accuracy and speed, making it particularly suitable for underwater image segmentation.
A flare removal network for night vision perception: Resistant to the interference of complex light
Authors: Liu Yan , Huang Guan , Qi Wenting , Li Yujie
Published: June 2024

The high‐precision visual perception results are easily affected by the lens flare issue when the image sensor is facing to strong light. The existing flare removal methods have poor robustness when confronted with flare interference caused by complex nighttime lighting, which has to preserve natural light source information. A simulated dataset for the removal of night flares is created to solve the problem of collecting complete paired training data, and night flare removal network (NFR‐Net) is proposed to remove the interference caused by various light disturbances at night. The light source extraction module is introduced to retain light source information realistically and effectively in night vision scenes. Extensive experimental results demonstrate that the proposed method is superior to the existing related methods in the various complex night vision scenes. The proposed NFR‐Net can enhance visual perception of nighttime images significantly and improve the performance of night vision tasks.
Decoupled dual‐channel loosely coupled transformer with hybrid nanocrystalline and ferrite core for current sharing of modular wireless power transfer system
Authors: Han Yu , Tian Zihan , Li Liangchen , Li Song , Yang Fuyao , Chen Jiaqi , Fan Rong , Zhao Haisen
Published: June 2024

Cross‐coupling and current sharing are the main problems faced by modular wireless power transfer (WPT) systems for electric vehicle (EV) applications. In this study, a decoupled dual‐channel wireless power transfer loosely coupled transformer (LCT) with a hybrid core composed of nanocrystalline and ferrite is proposed for modular WPT systems, as well as WPT systems with specific hybrid topology or detuned compensation. Firstly, the requirements of the LCT for modular parallel dual‐channel WPT system and detuned compensation are discussed. For these requirements, the structure and corresponding optimization design method of the decoupled dual‐channel LCT with a hybrid core is then proposed, and an LCT is designed with this method for the case study. Furthermore, the LCT is analysed by the finite element method (FEM). It is revealed that the mutual inductances of the proposed LCT between transmitting and receiving coils can be symmetrical under misalignment in multiple directions, while the cross‐coupling is eliminated. Finally, the designed LCT is manufactured and verified in a modular parallel dual‐channel WPT system. The experimental results show that the current and power sharing is realized under misalignment in multiple directions.
Parameter identification of PLL for grid‐connected inverter based on parameter sensitivity analysis
Authors: Li Fei , Feng Qiang , Chen Ping , Liu Yang , Cai Shuiliang , Wang Hanyu , Zhang Xing
Published: June 2024

Under the condition of weak grid, the phase‐locked loop (PLL) is one of the main reasons for the sub‐synchronous oscillation of the grid‐connected inverter. Therefore, it is necessary to identify the PLL parameters of the grid‐connected inverter for the analysis of the inverter operating performance. This paper uses the sequence impedance model and measured impedance data of grid‐connected inverter to construct the identification function for parameter identification of PLL, and the function is calculated by particle swarm optimization algorithm to overcome the nonlinear problem of sequence impedance model. In addition, the identification frequency band is selected based on PLL parameter sensitivity to improve the parameter identification accuracy under the same impedance measurement error. At different frequencies, the positive correlation between the sensitivity of the PLL parameters and the identification accuracy is proven to determine the definite frequency band for PLL parameter identification of grid‐connected inverter. Finally, the feasibility and effectiveness of the above research are verified by simulation and semi‐physical experiments.
Investigation into the origin of the soft excess in Ark 564 using principal component analysis
Authors: Lyu M. , Fei Z. Y. , Zhang G. B. , Yang X. J.
Published: June 2024

We combined a principal component analysis (PCA) and spectroscopy to investigate the origin of the soft excess in narrow-line Seyfert 1 galaxy Ark 564 with XMM-Newton observations over a period of ten years. We find that the principal components in different epochs are very similar, suggesting stable variability patterns in this source. More importantly, although its spectra could be equally well fitted by the two soft excess models, simulations show that the principal components from the relativistically smeared reflection model match the data well. At the same time, the principal components from the warm corona model show significant inconsistency. This finding indicates that the soft excess in Ark 564 originates from the relativistically smeared reflection, rather than the Comptonization in the warm corona, thereby favoring the reflection origin or the “hybrid” origin of the soft excess. Furthermore, the presence of the narrow absorption features in the spectra suggests that the soft excess is unlikely to originate from absorptions due to possible outflowing winds. Our results indicate that the PCA coupled with spectral analysis is a promising approach to exploring the origin of the soft excess in active galactic nuclei (AGNs).
Using CSST and ejecta-wind interaction in type II-P supernovae to constrain the wind-mass loss of red supergiant stars
Authors: Luo Jingxiao , Dessart Luc , Chen Xuefei , Liu Zhengwei
Published: June 2024

The properties of H-rich, type II-plateau supernova (SN II-P) progenitors remain uncertain, and this is primarily due to the complexities associated with red supergiant (RSG) mass loss. Recent studies have suggested that the interaction of the ejecta with a standard RSG wind should produce unambiguous signatures in the optical (e.g., a broad, boxy Hα profile) and in the UV (especially Ly α and Mg IIλλ 2795,  2802) a few years following the explosion. Such features are expected to be generic in all SNe II-P and can be utilized to constrain RSG winds. Here, we investigate the possibility of detecting late-time (0.3–10 years since explosion) SNe II-P in the NUV with the China Space Station Telescope (CSST). Convolving the existing model spectra of ejecta-wind interactions in SNe II-P with the transmission functions of the CSST, we calculated the associated multiband light curves, in particular, the NUV (255 nm–317 nm) band, as well as the NUV − r color. We find that the CSST will be able to detect the NUV radiation associated with ejecta-wind interaction for hundreds SNe II-P out to a few hundred Mpc over its ten-year main sky survey. The CSST will therefore provide a sizable sample of SNe II-P with the NUV signatures of ejecta-wind interaction. This will be helpful for understanding the mass loss history of SN II-P progenitors and their origins.
[Mg/Fe] and variable initial mass function: Revision of [α/Fe] for massive galaxies
Authors: Pernet Emilie , Boecker Alina , Martín-Navarro Ignacio
Published: June 2024

Observations of nearby massive galaxies have revealed that they are older and richer in metals and magnesium than their low-mass counterparts. In particular, the overabundance of magnesium compared to iron, [Mg/Fe], is interpreted to reflect the short star formation history that the current massive galaxies underwent early in the Universe. We present a systematic revision of the [Mg/Fe] – velocity dispersion (σ) relation based on stacked spectra of early-type galaxies with a high signal-to-noise ratio from the Sloan Digital Sky Survey. Using the penalized pixel-fitting (pPXF) method and the MILES single stellar population models, we fit a wide optical wavelength range to measure the net α-abundance. The combination of pPXF and α-enhanced MILES models incorrectly leads to an apparently decreasing trend of [α/Fe] with velocity dispersion. We interpret this result as a consequence of variations in the individual abundances of the different α-elements. This warrants caution for a naive use of full spectral fitting algorithms paired with stellar population models that do not take individual elemental abundance variations into account, especially when deriving averaged quantities such as the mean [α/Fe] of a stellar population. In addition, and based on line-strength measurements, we quantify the impact of a non-universal initial mass function on the recovered abundance pattern of galaxies. In particular, we find that a simultaneous fit of the slope of the initial mass function and the [Mg/Fe] results in a shallower [Mg/Fe]–σ relation. Therefore, our results suggest that star formation in massive galaxies lasted longer than what has been reported previously, although it still occurred significantly faster than in the solar neighbourhood.
A new causal and stable theory of viscous chiral hydrodynamics
Authors: Abboud Nick , Speranza Enrico , Noronha Jorge
Published: June 2024

We construct the general theory of first-order relativistic hydrodynamics for a fluid exhibiting a chiral anomaly, including all possible viscous terms allowed by symmetry. Using standard techniques, we compute the necessary and sufficient conditions for this theory to be relativistically causal in the nonlinear regime and for thermal equilibria to be linearly stable. This is the first theory of first-order chiral hydrodynamics suitable for numerical simulations.
Understanding the properties of the fireball with the polarization signature of thermal dileptons
Authors: Seck Florian , Friman Bengt , Galatyuk Tetyana , van Hees Hendrik , Speranza Enrico , Rapp Ralf , Wambach Jochen
Published: June 2024

Multi-differential measurements of dilepton spectra serve as a unique tool to characterize the properties of matter in the interior of the hot and dense fireball created in heavy-ion collisions. An important property of virtual photons is their spin polarization defined in the rest frame of the virtual photon with respect to a chosen quantization axis. Microscopic calculations of in-medium electromagnetic spectral functions have mostly focused on integrated yields which are proportional to the sum of the longitudinal and transverse components of the virtual photon’s self-energy, while photon polarization results from the difference of these components. As the processes that drive the medium effects in the spectral function change with invariant mass and momentum, this becomes a powerful tool for studying the medium composition. We present the polarization observables of thermal virtual photons as a function of mass and momentum and confront the results with existing measurements from HADES and NA60.
Bottom-hadron production in high-energy pp and heavy-ion collisions
Authors: He Min
Published: June 2024

The hadro-chemistry of bottom quarks produced in hadronic collisions encodes valuable information on the mechanism of color-neutralization in these reactions. We first compute the chemistry of bottom-hadrons in high-energy pp collisions employing statistical hadronization with a largely augmented set of states beyond the currently measured spectrum. This enables a comprehensive prediction of fragmentation fractions of weakly decaying bottom hadrons for the first time and a satisfactory explanation of the existing measurements in pp collisions at the LHC. Utilizing the bottom hadro-chemistry thus obtained as the baseline, we then perform transport simulations of bottom quarks in the hot QCD matter created in PbPb collisions at the LHC energy and calculate the pertinent bottom-hadron observables. The transverse momentum (pT) dependent modifications of the bottom baryon-to-meson ratio (Λb0/B-) relative to their pp counterparts are highlighted as a result of bottom quark diffusion and hadronization in the Quark-Gluon Plasma (QGP). We finally summarize the heavy quark (charm vs bottom) diffusion coefficients as extracted from transport simulations and compare them to result from recent full lattice QCD computations.
Quarkonia as probes of initial and final states in small systems with ALICE
Authors: Choudhury Subikash
Published: June 2024

The multiple parton−parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p−Pb collisions, the so-called small systems. At LHC energy, MPIs affect both soft and hard scales of the event. Since quarkonium production involves both, it can be an excellent tool to understand the role of MPIs in small systems. Study of multiplicity dependent quarkonium production provides an indirect probe of MPIs in hadronic collisions. Also, relative production of excited-to-ground quarkonium states as a function of multiplicity are sensitive to final state effects. Cross section measurements of different quarkonium states are also important to understand their production mechanisms. In these proceedings, first preliminary results of ψ(2S)-over-J/ψ cross section measurements at mid and forward rapidity (y) from Run 2 and Run 3 pp collisions at √S and 13.6 TeV, respectively will be presented. Preliminary results on ϒ(nS) states (n = 1,2) cross sections and final multiplicity dependent measurements of excited-to-ground states quarkonium yields, at forward y, in pp collisions at √S TeV will be shown. In addition, few performance plots from Run 3 in the quarkonium sector will be presented and discussed.
Limiting attractors in heavy-ion collisions—The interplay between bottom-up and hydrodynamic attractors
Authors: Boguslavski Kirill , Kurkela Aleksi , Lappi Tuomas , Lindenbauer Florian , Peuron Jarkko
Published: June 2024

In this contribution to the Quark Matter 2023 proceedings, we study the hydrodynamization process in heavy-ion collisions using QCD kinetic theory and introduce the new concept of limiting attractors. They are defined via an extrapolation of observables to vanishing and infinite couplings. We find that the pressure ratio exhibits both a hydrodynamic and a bottom-up limiting attractor, while the ratios of hard probes transport coefficients q^zz/q^yy and κT/κz are better described in terms of the new bottom-up limiting attractor.
Measurement of in-medium modification of energy-space structure of jets via γ and π0 triggered hadrons in Au+Au collisions at RHIC
Authors: Connors Megan ,   PHENIX Collaboration
Published: June 2024

Since the discovery of the jet quenching at RHIC, the in-medium interaction of hard scattered partons with the nuclear medium created by highenergy heavy-ion collisions has been an excellent tool to understand not only the transport properties of the medium but also its time evolution towards hadronization. The multi-differential measurement of the high momentum twoparticle correlations can probe a particular space-time window as a function of energy transfer. Comparing the correlations with the prompt photon-triggered hadron spectra, one can extract the property of the medium from various aspects and contribute to distinct models. The PHENIX experiment at RHIC has collected its highest statistics of the γ and π0 triggered hadron events in Au+Au collisions at √SNN = 200 GeV in the RHIC Year-2014 run, and measured not only the inclusive spectra of the triggered hadrons but also the angle and energy dependent IAA and DAA. We will discuss the in-medium modification of the energy-space structure of the jets at the RHIC energies with the results obtained.
Excited hadron channels in hadronization
Authors: Fries Rainer J. , Purcell Jacob , Kordell Michael , Ko Che-Ming
Published: June 2024

The proper treatment of hadronic resonances plays an important role for many aspects of heavy ion collisions. We expect this to be the case also for hadronization, due to the large degeneracies of excited states, and the abundant production of hadrons from their decays. We show how a comprehensive treatment of excited meson states can be incorporated into quark recombination, and in extension, into Hybrid Hadronization. We discuss in detail the quantum mechanics of forming excited states, utilizing the Wigner distribution functions of angular momentum eigenstates of isotropic 3-D harmonic oscillators. We describe how resonance decays can be handled, based on a set of minimal assumptions, by creating an extension of hadron decays in PYTHIA 8. Finally, we present a study of hadron production by jets using PYTHIA and Hybrid Hadronization with excited mesons up to orbital angular momentumL= 4. We find that states up toL= 2 are produced profusely by quark recombination.
Strange hadron production in small system using the STAR Detector
Authors: Aggarwal Ishu
Published: June 2024

Strangeness enhancement has long been considered a signature of quark-gluon plasma formation in heavy-ion collisions. Recently, strangeness enhancement has also been observed in small systems at the Large Hadron Collider (LHC), but the underlying physics is not yet fully understood. This motivates us to study of strange hadron production in small system at Relativistic Heavy Ion Collider (RHIC). In this proceedings, we present new measurements of strange hadrons (KS0, Λ(¯Λ)) in d+Au collisions at √SNN = 200 GeV, collected by the STAR experiment in 2016. We will report pT spectra, dN/dy, , nuclear modification factor and YAsym of these particles in d+Au collisions.
Pinning down the origin of collective flow in small systems with ALICE
Authors: Zhao Mingrui
Published: June 2024

In this proceeding, the new preliminary results of anisotropic flow in pp, p–Pb, and Pb–Pb collisions measured with ALICE are presented. The highlights include the flow of charged particles, correlations and fluctuations of flow vectors, and correlations between the mean transverse momentum and flow coefficients, ρ(vn2,[pT]). We compare our results to state-of-the-art theoretical models, allowing us to study contributions from initial momentum anisotropies to final anisotropic flow and understand how anisotropic flow is developed from the initial geometry through the system’s dynamic evolution in hadron collisions of different sizes.
STAR forward detector upgrade status and performance
Authors: Wang Zhen
Published: June 2024

An upgrade to the STAR detector system at forward rapidities has been completed before the RHIC RUN 2022. It consists of the Forward Tracking System (FTS) and the Forward Calorimeter System (FCS). The Forward Tracking System is composed of a Silicon Tracker and a small-strip Thin Gap Chamber Tracker. The Forward Calorimeter System contains an Electromagnetic Calorimeter and a Hadronic Calorimeter. These systems cover the pseudorapidity region of 2.5 < η < 4, providing detection capabilities for neutral pions, photons, electrons, jets, and charged hadrons. This enables the STAR experiment to study cold QCD physics at very high and low regions of Bjorken x and to explore the longitudinal structure of the initial state in relativistic heavyion collisions by measuring the decorrelations at large η. This proceeding will introduce the STAR forward upgrade, its current status, and its performance during the STAR Run22.
Simulation Model for the Formation of Distributive Routes in a Dynamic Urban Environment
Authors: Shramenko Vladyslav , Shramenko Natalya , Hupfer Christoph
Published: June 2024

The share of small shipments in the total volume of cargo transportation has increased significantly. However, irrational routes are formed, customers’ requirements for timely delivery of goods are ignored, and vehicles of irrational carrying capacity are used on distribution routes, which significantly increases logistics costs and the cost of goods. The limitations and problems of existing solutions were analysed. Theoretic methods are not applicable to the Vehicle Routing Problem with more than 17 customers due to computational complexity. The heuristic methods that were examined focus on creating the shortest routes but do not consider customer priority, route restrictions, or potential service strategies. Therefore, a metaheuristic Genetic algorithm was chosen for route formation tasks. The research is aimed at developing a simulation model, which is based on the use of a genetic algorithm, to create optimal delivery routes for small shipments to customers within a city. The study includes modelling the route formation using a genetic algorithm for various types of cargo bicycles and trucks in a dynamic urban environment. As a result of simulation modelling, distribution routes were formed and operational parameters were optimized on cargo delivery routes in the city for various types of vehicles with different carrying capacities.

This paper conducts a preliminary exploration of Artificial Intelligence (AI) for emotion recognition, particularly in its business applications. Employing adaptive technologies like machine learning algorithms and computer vision, AI systems analyze human emotions through facial expressions, speech patterns, and physiological signals. Ethical considerations and responsible deployment of these technologies are emphasized through an intense literature review. The study employs a comprehensive bibliometric analysis, utilizing tools such as VOSViewer, to trace the evolution of emotion-aware AI in business. Three key steps involve surveying the literature on emotion analysis, summarizing information on emotion in various contexts, and categorizing methods based on their areas of expertise. Comparative studies on emotion datasets reveal advancements in model fusion methods, exceeding human accuracy and enhancing applications in customer service and market research. The bibliometric analysis sheds light on a shift towards sophisticated, multimodal approaches in emotion recognition research, addressing challenges such as imbalanced datasets and interpretability issues. Visualizations depict keyword distributions in research papers, emphasizing the significance of “emotion recognition” and “deep learning.” The study concludes by offering insights gained from network visualization, showcasing core keywords and their density in research papers. Based on the literature, a SWOT analysis is also conducted to identify the strengths, weaknesses, opportunities, and threats associated with applying emotion recognition to business. Strengths include the technology’s high accuracy and real-time analysis capabilities, enabling diverse applications such as customer service and product quality improvement. However, weaknesses include data bias affecting the AI model’s quality and challenges in processing complex emotional expressions. Opportunities lie in the increasing number of studies, market size, and improving research outcomes, while threats include privacy concerns and growing competition.

Zeitraum und ausgewählten Stoffwechselparametern unter Berücksichtigung
verschiedener Rassen

Ziel Die Ergebnisse dieser Studie beschreiben die Zusammenhänge zwischen
der Körperkondition von Milchkühen und ausgewählten Stoffwechselparametern im
Blut im peri- und postpartalen Zeitraum unter Berücksichtigung dreier hiesiger
Milchviehrassen in Oberbayern und im Allgäu.

Material und Methoden Kühe von 3 Milchviehrassen (Braunvieh [BV],
Fleckvieh [FL], Holstein Friesian [HF]) wurden auf 68 Betrieben in
Süddeutschland in 7 aufeinanderfolgenden Wochen untersucht. Sowohl bei
trockenstehenden Tieren als auch bei laktierenden (5.–65. Tag in Milch) wurden
Blutparameter (Beta-Hydroxy-Butyrat, Freie Fettsäuren, Creatinin,
Aspartat-Aminotransferase, Gamma-Glutamyltransferase, Glutamatdehydrogenase,
Gesamtprotein, Albumin, Creatinkinase) und Körperkondition (Body Condition Score
[BCS], Rückenfettdicke [RFD]) untersucht. Für die Datenauswertung wurden
explorative und deskriptive Statistik genutzt.

Ergebnisse Betrachtet man die Differenz der Ergebnisse der
Konditionsbewertungen vor und nach der Kalbung, wies das FL bei der RFD die
geringste Differenz auf. Bei FL und BV ließ sich eine Tendenz zu höheren
RFD-Werten bei erstlaktierenden Kühen erkennen. Sowohl bei dem FL als auch bei
dem HF lagen die NEFA-Werte der höherlaktierenden Kühe unter den Werten der
Erstlaktierenden. Die höherlaktierenden BV- und FL-Tiere wiesen höhere BHB-Werte
auf. Die Korrelation zwischen RFD und BCS zeigte bei den HF-Kühen das höchste
R2 (0,53). BV und FL lagen mit 0,42 (BV) bzw. 0,37 (FL) darunter.
Die BHB-Werte aller 3 Rassen stiegen in den Wochen 2–4 post partum an. Die
NEFA-Werte waren bei allen 3 Rassen vorrangig in der 1.–3. Woche p.p. erhöht,
wenn die RFD p.p. abnahm. Die NEFA-Werte waren am höchsten, wenn die
Körperkonditionsabnahme und somit die Fettmobilisation am größten waren.

Schlussfolgerung und klinische Relevanz Körperkonditionsbeurteilung (BCS
auf Einzeltier- und Herdenebene, RFD auf Einzeltierebene) ist ein wichtiges
Instrument für das Tiergesundheitsmonitoring. Durch die erkennbare
Rassespezifität kann expliziter auf die Milchviehherden eingegangen werden. Ziel
ist es, den Energiehaushalt der Kühe in der Frühlaktation optimal zu steuern, um
die Gesundheit der Tiere zu erhalten.

Background Simultaneous multifrequency (SiMFy) is a time-saving and reliable stimulus to determine the frequency tuning of ocular vestibular-evoked myogenic potential (oVEMP); however, the absence of 4000 Hz in SiMFy potentially makes it a less potent tool for the diagnosis of superior semicircular canal dehiscence, a pathology with an ever-increasing prevalence. Further, SiMFy was validated using only the infraorbital (IO) electrode montage. However, the recordings obtained using the IO montage might be susceptible to reference contamination introduced by a small separation between the recording electrodes and also susceptible to reflex impurity due to the spatially displaced reference electrode from the inferior oblique muscle, rendering it vulnerable to picking up responses from other muscles. Nonetheless, little is known about the similarities/differences between the SiMFy-induced oVEMPs using alternate montages (belly-tendon [BT], chin-reference [CR], and sternum-reference [SR]) and the nonsimultaneous multifrequency oVEMPs (NSM-oVEMPs) using the IO montage.

Purpose of the Study To develop a modified SiMFy stimulus and investigate its effects on frequency tuning of oVEMP using various electrode montages.

Research Design Within-subject experimental design.

Study Sample Thirty-three healthy adults aged 20 to 30 years.

Data Collection and Analysis Tone bursts of octave and mid-octave frequencies from 250 to 4000 Hz were generated and concatenated to create the modified SiMFy stimulus. All participants underwent NSM oVEMPs and modified SiMFy oVEMPs using BT, CR, SR, and IO montages simultaneously. The response rate, peak-to-peak amplitude, and frequency tuning were compared between NSM-oVEMP and modified SiMFy oVEMP and also between the electrode montages.

Results BT montage recorded the largest amplitude among the montages in NSM stimulation and modified SiMFy stimulation. Although the response rates were comparable, the modified SiMFy produced significantly lower oVEMP amplitudes than the NSM stimulation within each electrode montage (p < 0.05). A moderate-to-strong agreement on frequency tuning existed between the NSM stimuli and modified SiMFy stimulus for all the montages, except for the SR montage.

Conclusions Although the modified SiMFy produces smaller amplitude oVEMPs than the NSM stimulation for the respective montages, its use in combination with the BT montage yields higher response rates and larger peak-to-peak amplitudes than the NSM recording using IO montage.

Purpose The purpose of this systematic review is to compare the clinical outcomes of midcarpal arthrodesis with triquetrum excision against midcarpal fusion without the excision of triquetrum performed using modern osteosynthesis technology.

Methods A systematic review of publications in PubMed, Medline, EMBASE, and Cochrane Database of Systematic Review was conducted. The studies that utilized osteosynthesis techniques other than Kirshner wire, with at least 10 patients, and had a minimum one-year follow-up period in English language were included. The quality of studies were evaluated using validated tools for assessing observational studies. Union rate, functional outcomes and revision/complication rates were collected and analyzed.

Results A meta-analysis was not possible. Based on pooled data the flexion-extension arc improved by 6 degrees for midcarpal arthrodesis group with triquetrum excision, but decreased by 11 degrees in the group without. The radial-ulnar arc improved by 5 degrees in the triquetrum excision group, but decreased by 3 degrees in the triquetrum preserving group. Improvement in grip strength appears to be better in the triquetrum preserving group (10 kg as opposed to 1 kg), while there were no observable difference in pain score.

Conclusions The literature lacked good comparison studies to examine the role of triquetrum excision in midcarpal fusion. While midcarpal fusion with triquetrum excision appeared to yield better ROM in the pooled data, studies with direct comparison of the two techniques are required to fill in the gap.

The field of cholangioscopy is undergoing rapid evolution, marked by continuous innovation. The advent of SpyGlass cholangioscopy has initiated a new chapter, transforming the practice with advancements that include single-operator procedures and the introduction of disposable cholangioscopes. Despite these strides, significant needs remain, including enhancement of optical imaging, improving maneuverability, and expansion of therapeutic channels. This article delves into the recent progress within cholangioscopy, with a particular focus on the clinical applications of the Leinzett Lan-EP-3516 cholangioscope for the management of portal biliopathy. We present a detailed case study demonstrating how this cutting-edge cholangioscope—distinguished by its various sizing options and compatibility with portable devices for immediate imaging—played an important role in the successful treatment of a distal common biliary duct stricture and choledocholithiasis. The device's cost-effectiveness and superior imaging quality signify a notable advancement in cholangioscopic technology, facilitating enhanced treatment pathways for patients with complex biliary disorders. This case exemplifies the dynamic and expanding utility of cholangioscopy in therapeutic interventions and underscores its escalating significance in clinical settings.
The Comparison between Direct Graft Fixation using a Biotenodesis Screw Combined with Early Mobilization versus a Traditional Knot Fixation with 6-Week Immobilization of Adams–Berger Triangular Fibrocartilage Complex Reconstruction

Several surgical techniques exist for triangular fibrocartilage complex (TFCC) reconstruction, one being the Adams–Berger technique. Direct graft fixation is an emerging option for this reconstructive technique. This study compared the outcomes of TFCC reconstruction according to the Adams–Berger technique using direct graft fixation with a biotenodesis screw and early mobilization against the traditional knot technique with a 6- week cast immobilization. Results demonstrated that the direct fixation technique with early mobilization led to significantly higher patient satisfaction and earlier return to work. A more rapid recovery of range of motion and grip strength, as well as reduced pain intensity, was also noted. The study supports the effectiveness of direct graft fixation with a biotenodesis screw and early mobilization in TFCC reconstruction, offering improved patient outcomes and potentially reducing health care costs. Further research with larger sample sizes is warranted to reconfirm these findings.

Objective Health care-associated infections (HAIs) are important causes of morbidity and mortality in neonatal intensive care units (NICUs). This study aimed to evaluate the frequency of HAIs and related factors in the NICU.

Methods HAIs detected and monitored by daily active surveillance by the Infection Control Team at Necmettin Erbakan University Faculty of Medicine NICU between January 1, 2017 and December 31, 2022 were evaluated retrospectively. There were a total of 43 incubators in our hospital's NICU (19 secondary level units and 24 tertiary level). Between 2017 and 2022, there was an average of 982 admissions to the NICU per year.

Results A total of 5,895 newborns and 74,726 patient days were monitored in the study. The average HAIs rate for all study years was 3.4% and the incidence density was 2.68 per thousand patient days. The highest HAI rate was in newborns with birth weights < 750 g. A total of 201 HAIs were detected in 172 patients. Bloodstream infection (BSI) was the most frequent HAI. The most frequent pathogens were Klebsiella spp. (44.8%), methicillin-resistant coagulase-negative staphylococci (CoNS) (24.4%), and Acinetobacter spp. (11.6%). Note that 88.5% of Enterobacterales were extended-spectrum beta-lactamase producers, and 26% of Klebsiella spp. were carbapenem-resistant. No colistin resistance was detected in Pseudomonas aeruginosa and Acinetobacter spp. Methicillin resistance was detected in 86.5% of CoNS and 50% of Staphylococcus aureus. The vancomycin resistance rate in Enterococcus spp. was 40%. Note that 16.7% of Candida spp. were fluconazole-resistant; no resistance to caspofungin was found. The most common risk factors for development of HAI were prematurity, umbilical catheter use, total parenteral nutrition, and mechanical ventilation. The mortality rate in patients with HAIs was 20.9%.

Conclusion HAIs, including those caused by multidrug-resistant Gram-negative bacteria, are an important problem in our hospital, and also globally. Active surveillance should be continued, and changes over the years evaluated. Infection control programs should be executed by determining the risk and mortality factors attributed to infection and their implementation should be closely monitored. These practices will increase success in the fight against HAIs and antimicrobial resistance.

A lot of previous research has focused on the public’s intentions to support organizations based on their actions related to Corporate Social Responsibility (CSR). However, people’s perceptions of CSR during challenging times are yet to be fully explored. This study aims to fill this gap by investigating the relationship between the public’s emotional, cognitive, and behavioral responses to CSR during uncertain times (i.e., a global pandemic). A total sample of 407 responses were collected during the first wave of the global pandemic across two countries, representing the European and African continents. The results show that in challenging times, negative emotions appear to fade into the background and do not play a significant role. Interestingly, cognitive evaluations (mind) are the strongest predictors of perceptions of CSR, while positive emotions (heart) are the key drivers of behavioral response toward the company. Theoretical and managerial implications are also discussed.
