Published: February 2025

ZusammenfassungDie Auskultation ist eine der ärztlichen Schlüsselkompetenzen in der körperlichen Untersuchung. Hauptproblem der Auskultation ist die fehlende Objektivierbarkeit der Befunde und die große Abhängigkeit von der Erfahrung des Untersuchenden. Die Auskultation mittels Machine Learning und mithilfe neuronaler Netzwerke verspricht großes Potenzial für die Lösung dieser Probleme im klinischen Alltag.Es erfolgte eine selektive Recherche nach Studien in PubMed, anhand derer die Möglichkeiten des Machine Learnings in der medizinischen Diagnostik sichtbar werden.In allen detektierten Studien konnten signifikante Unterschiede zwischen den jeweiligen Testgruppen zugunsten der Künstlichen Intelligenz (KI) gezeigt werden. Neben den positiven Studienergebnissen konnten auch die Limitationen der KI analysiert und kritisch hinterfragt werden.Die medizinische Forschung befindet sich auf dem Gebiet der Künstlichen Intelligenz noch in den Anfängen. Perspektiven und Grenzen der KI müssen weiter untersucht werden und bedürfen großer Aufmerksamkeit in der Zusammenarbeit von Klinikern, Wissenschaftlern und KI-Experten. Öffentlich geförderte Projekte wie DigitaLung (Digitales Auskultationssystem zur Differenzialdiagnose von Lungenerkrankungen mittels Machine Learning), welches mittels KI die Lungenauskultation perspektivisch verbessern soll, helfen dabei, den diagnostischen Nutzen der KI für die Patientenversorgung zu erschließen, und könnten in Zukunft Möglichkeiten die Versorgung verbessern.
Occurrence of antibody titers against Borna disease virus in alpacas
in Bavaria, Germany
Authors: Kirmayer Leonie Isabelle , Lendl Christine , Wittek Thomas 
Published: February 2025

AbstractThe increasing population of alpacas in Germany requires comprehensive
studies on potential disease. Borna Disease, an infection believed to be
primarily transmitted by the bicolored, white-toothed- shrew (Crocidura
leucodon) to animals and humans, poses significant concerns. This
study aimed to assess the occurrence of Borna Disease virus (BoDV)
antibodies in alpacas in Bavaria, Germany, and explore associated
epidemiological factors.A total of 424 serum samples were collected from 65 alpaca farms in Bavaria,
which were selected voluntarily. In addition, questionnaires were filled out
by the animal owners gathering information on husbandry and disease
awareness of the owners.The results revealed an occurrence rate of nearly 9%, with one in every
fourth farm housing at least one antibody-positive animal. While no
significant differences were observed in breed, age, or gender, regional
endemic areas were identified, coinciding with the presence of the
shrew.This study underscores the widespread occurrence of BoDV antibodies in
alpacas in Bavaria, emphasizing the importance of hygiene management and
increased awareness of the disease among animal owners and
veterinarians.

Published: February 2025

Background Various reactions are involved in the phases of activation and further propagation of coagulation in space. The effects of different anticoagulants on these phases are unknown. Our aim was to study how different anticoagulants affect the activation and propagation phases of coagulation.
Materials and Methods Coagulation in the presence of low-molecular-weight heparin (nadroparin), and direct oral thrombin or factor Xa inhibitors (dabigatran and rivaroxaban, respectively) was studied in vitro and ex vivo via a global blood coagulation assay (Thrombodynamics-4D), which allows simultaneous analysis of thrombin activity in space and the clot growth rate. The ex vivo measurements were carried out in dynamics (8–9 days). The presence of asymptomatic thrombosis after 7 to 8 days of treatment was determined for each group of patients via ultrasound of the lower extremities.
Results All the tested anticoagulants inhibited thrombin generation but resulted in different patterns of thrombin spatial distribution and clot growth. The reversible inhibitors—dabigatran and rivaroxaban—inhibited the initiation phase of coagulation, while further clot growth was altered moderately. Irreversible nadroparin weakly affected the initiation phase of thrombin generation, but unlike dabigatran and rivaroxaban, it could completely suppress spatial thrombin propagation. Asymptomatic thrombosis was observed in 0%, 11%, and 29% of the patients in the nadroparin, dabigatran, and rivaroxaban groups, respectively.
Conclusion Antithrombin-dependent and independent inhibitors act differently on different phases of coagulation. High concentrations of dabigatran or rivaroxaban are insufficient to completely prevent fibrin clot growth, but even small amounts of heparin completely suppress this growth, due to factor IXa inhibition.

Published: February 2025

ZusammenfassungDie Impfung ist eine der wichtigsten Maßnahmen zur Verhinderung von
Infektionskrankheiten und deren Verbreitung. Die Impfungen gegen Tetanus und
West-Nil-Virus sind essentiell um das einzelne Pferd vor der Erkrankung zu
schützen. Diese Infektionen sind nicht kontagiös und werden nicht von Tier zu
Tier weitergegeben. Equine Influenza- (EIV) und Herpesvirusinfektionen (EHV)
sind dagegen hochansteckende, übertragbare Erkrankungen. Neben dem Schutz des
geimpften Einzeltiers soll durch die Impfung möglichst vieler Pferde gegen EIV
und EHV eine breite Herdenimmunität erzielt werden, die Infektionsketten
unterbricht, und so das Einzeltier zusätzlich vor der Erkrankung schützt. Die
Impfung gegen Tetanus sowie Equine Influenza- und Herpesviren gelten als
Core-Impfung beim Pferd. Die Impfung gegen das West-Nil-Virus wird in den
bisherigen Verbreitungsgebieten in Mitteldeutschland und seit 2024 in der
gesamten norddeutschen Tiefebene empfohlen. Je nach weiterer Ausbreitung des
Virus ist perspektivisch die Impfung im gesamten Bundesgebiet anzustreben. Neben
den genannten sind für das Pferd Impfstoffe gegen Dermatomykose, Druse,
Rotavirusinfektionen, Equine Virus Arteriitis und Tollwut zugelassen. Der
Einsatz dieser Impfstoffe kann im Einzelfall sehr sinnvoll sein.

Abstract
Background/Objective Acute Type A aortic dissection (ATAAD) is a life-threatening condition requiring timely surgical intervention. Despite successful surgery, postoperative outcomes are frequently suboptimal due to the high frequency of cardiovascular risk factors. This study examines baseline cardiovascular risk factors in a population of ATAAD patients in the Netherlands. Additionally, this study outlines the protocol for a randomized controlled trial, designed to improve postoperative management.
Methods Baseline data were collected from patients with ATAAD. Data were gained through the Stichting Aorta Dissectie Nederland, a Dutch association for aortic dissection patients. The data included information on cardiovascular risk factors and health-related quality of life. A survey was further conducted, to gain more insights into the ATAAD postoperative care experiences of cardiac and vascular surgeons.
Results Among the 50 ATAAD patients in our study, we found significant cardiovascular risk factors, including smoking (36.7%), obesity (34.2%), and hypertension (51.3%). In the surgeon survey (N = 48), 84% of respondents highlighted the significance of lifestyle changes for patients, underscoring the need for individualized risk management. These findings underscore the need for tailored postoperative management programs aimed at improving patient outcomes.
Conclusion The results of our study highlight that ATAAD patients require comprehensive postoperative care management strategies. The ultimate goal is to enhance long-term patient outcomes and improve health-related quality of life. To address this need, the TRAIN (Targeted caRdiovAscular rIsk reductioN) Health Awareness platform seeks to implement personalized eHealth-based lifestyle interventions.

AbstractThis is an image-based clinical vignette showing pathologic findings typical of subcutaneous fat necrosis of the newborn (SFNN). The infant—a 15-month-old girl—presented with indurated subcutaneous masses of unknown etiology. This case is a reminder that SFNN, while more common in the newborn period, can occur throughout infancy. It also reminds us that the rare metabolic disorder (Lesch–Nyhan syndrome) may be associated with lesions that can appear somewhat similar under the microscope.

Solar radiation pressure models for BDS-3 IGSO: impacts and improvement from observation geometry
Authors: Yang Chao , Guo Jing , Xu Xiaolong , Wang Longyu , Zhao Qile 
Published: February 2025

Abstract
The orbit quality of BDS-3 inclined geosynchronous orbit (IGSO) satellites is limited by the observation geometry as well as dynamic models. Regarding ground L-band data, the maximum nadir angle for IGSO satellites is approximately 9°. However, with BDS-3 Ka-band inter-satellite link (ISL) data, the maximum nadir angle can reach up to 45°, which significantly improves observation conditions. This study investigates the impact of ISL data on 5-parameter reduced extented CODE orbit model (ECOM1) compared with that from ground L-band data only. It is observed that the estimates of the ECOM1 parameter become more precise by using ISL data, particularly for D
0 as well as those in B direction. Y
0 bias shows noticeable thermal radiation effects for C38 and C39. The Sun-elevation angle dependent clock linear-fit residuals are reduced significantly for C39 or almost vanished for C38 and C40. By analyzing the solar radiation pressure (SRP) accelerations for the solutions with L-band only or L and ISL data, we observed that the radial acceleration differences show opposite dependency with these in the B direction. The similar phenomenon can be observed in the differences of solutions based on ECOM2 and ECOM1 with L-band data only. These reveal that the deficiency of the ECOM1 for the non-cubic satellites can be partly compensated by using better observation geometry from ISL data, as better estimates in B direction can be obtained. Based on the adjustable box-wing model, the optical coefficients of BDS-3 IGSO are calibrated with L-band and ISL measurements. By incorporating these estimates into the box-wing model used as the a priori SRP to augment ECOM1, the Sun-elevation angle dependent errors in clock offsets are mitigated. And the RMS of clock linear-fit is further reduced by approximate 1.2 cm by using the estimates from L-band and ISL data than that from L-band-only data. This demonstrates the positive contribution for ISL on SRP modeling of BDS-3 IGSO satellites.
Numerical simulation of domain wall and first-order phase transition in an expanding universe
Authors: Li Yang , Jia Yongtao , Bian Ligong 
Published: February 2025

Abstract
We numerically study the domain walls (DWs) dynamic through 3D lattice simulation, and show that DWs formed by the breaking of a discrete symmetry in the early Universe can be dissipated by a later cosmic first-order phase transition (PT), even if the DWs have entered the scaling regime. The decay speed of the DWs is characterized by the bubble nucleation rate of the first-order PT. The produced gravitational wave (GW) spectrum can be dominated by the first-order PT and is of a different shape in comparison to that of the DWs. The mechanism can be probed by the current and upcoming GW detectors.

Published: February 2025

Abstract
The technology of thermal holding cycles using a combustion ventilation system in the palm sugar crystallization machine has been developed and constructed. The thermal cycles were automatically controlled by sequentially both opening and closing a ventilation system embedded in a sawdust briquette burner. The system doses the amount of flame from the burner to heat the crystal palm sugar in the pan. A control circuit module for the combustion system and a thermocouple in the pan as well as data acquisition software (DAC) for data recording have been implemented. The performance of the prepared combustion control system in the machine was successfully tested by measuring the water content of sugar crystals. It has been found that crystal sugar with the best water content, reaching the standard of 2.7% has been produced by holding the heating temperature at 70°C for 22 minutes. The conclusion of this study is that the thermal holding cycles using the combustion control system are suitable technological equipment for heating palm crystal sugar and are characterized by at least three advantages, namely precise control and shorter heating time, as well as higher sugar product quality.

Abstract
Heavy metals, including lead (Pb), have contaminated a number of rivers that provide drinking water to the residents of West Java. Even at low amounts, lead is a dangerous heavy metal. It is crucial to detect Pb in liquid samples for this reason. Using three electrodes—the Working Electrode (WE), the Counter Electrode (CE), and the Reference Electrode (RE)—an electrochemical approach was used to detect the presence of Pb. A modification was performed to the WE in order to improve the sensitivity, selectivity, and response time of the Pb detection. This work modified WE using ZnO/PVA nanocomposites doped with graphene. ZnO is a frequently used nanomaterial that has been shown to improve heavy metal detection sensitivity. ZnO has a band-gap energy of 3.37 eV and a high electron mobility of about 3 cm2/V.s. ZnO also has high surface area, which makes it possible for positively charged heavy metal ions to attach to active sites. ZnO nanoparticles are treated with PVA to create nanocomposites with flexible surfaces. To increase electrical conductivity in ZnO/PVA nanocomposites, graphene can be used as a doping agent. In this work, a thin film of graphene was synthesized from 0.1 grams of ZnO, 1.5 grams of PVA, and 0.324 grams of graphene. The surface and contents of the thin film are then examined using an Scanning Electron Microscope (SEM) and a Energy Dispersive Spectrophotometer (EDS), respectively. The thin film’s electrochemical characteristics were then investigated through the application of Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV). The CV and SWV technique results clearly indicate that ZnO/PVA doped graphene will be involved in the redox reaction with Pb via 0.1 M NaOH. The peak anodic current at CV and oxidation peak at SWV increases with the concentration of Pb, according to the results of two methods for detecting Pb at concentrations of 0, 0.5, 2, 3, 4, and 5 ppm. These results showed that thin film modified with ZnO/PVA nanocomposites doped with graphene have better Pb detection sensitivity capabilities than those without.

Abstract
Electrical submersible pumps are constrained by limited shaft brake horsepower for well production. To address this, this study develops a combined electrical submersible pump and gas lift system aimed at enhancing pump performance. The objectives are to reduce the number of stages, lower the energy requirements of the combined system, decrease the power consumption of the pump motors, and increase the production flow rate. Energy requirements for the pump are determined based on the generated pressure profile, and power gain is calculated from the resulting output. This research employed a simulation approach, with design and modeling carried out using software. The integration of the pump and gas lift system led to a 19.4% increase in production compared to a single pump system, a 32.45% reduction in energy consumption across five wells, and a decrease in power generation to stay within shaft brake horsepower limits

Abstract
A wheelchair is a tool that can be used as a tool for people who have limited mobility, one of which is the older people. A wheelchair is a tool that can be used as a tool for people who have limited mobility, one of which is the older people. Electric wheelchairs with joystick controllers were developed to make things easier for the older people, where electric wheelchairs that use joystick controllers are more profitable than manual wheelchairs. Electric wheelchairs with joystick controls allow seniors to easily operate the wheelchair using their hands or fingers. The use of joystick controllers on electric wheelchairs allows seniors to control the direction and speed of movement of the wheelchair with simple and intuitive movements. However, despite all the advantages of an electric wheelchair with a joystick controller, you must pay attention to the ergonomics and placement of each component used so that it remains stable for the older people. Apart from that, there is a geofencing feature used on this electric wheelchair. This feature can increase the safety of electric wheelchair users because it can provide notification to family or responsible parties so that the location of the electric wheelchair can be detected. From the field test results, it was found that the maximum speed obtained after covering a distance was 8 km/hour. Non-stop travel time using a wheelchair is 8–12 hours if used on a flat road.
Numerical Simulation of Shark Fin Vortex Generator Placement with Staggered Arrangement on The Left and Right Walls of a Passenger Bus
Authors: Putri T P , Widodo W A 
Published: February 2025

Abstract
In this study, the impact of using Shark Fin Vortex Generators (SFVG) on the aerodynamics of passenger buses is evaluated through numerical analysis. The analysis shows that at a speed of 120 km/h, buses equipped with SFVG record higher total force values, specifically 3624, 3564, and 3514 for variations of x/l 85, x/l 90, and x/l 95 respectively, compared to other speed and x/l variations. The drag coefficient (CD) for buses with SFVG is 0.775, 0.744, and 0.738 for x/l 85, 0.748, 0.736, and 0.728 for x/l 90, and 0.695, 0.684, and 0.676 for x/l 95. These values indicate that SFVG can slightly reduce drag by improving airflow and reducing turbulence. However, the obtained lift coefficient (CL) values show a decrease as speed and the distance of the vortex generator increase, with lower CL values at higher speeds. This study indicates that SFVG has the potential to increase speed and reduce drag but may also increase lift, affecting vehicle stability. Further research is needed to better understand the impact of SFVG on the overall energy efficiency and aerodynamic performance of buses.

Published: February 2025

Abstract
The WC-Co based cemented carbide has been widely used in engineering applications because of its remarkable properties high hardness, good toughness and excellent wear resistance. In the fabrication process, the powder preparation technique plays an important role in consolidating sintered compacts. In the present study, we investigate the effect of mechanical milling on the spark plasma sintering of WC-12Co cemented carbide. Two different powders of the WC-12Co, namely unmilled and milled powders, were prepared. The powder milling was carried out using a shaker mill under wet milling for 2 hours. Hereafter, the milled powder was dried at room temperature for 24 hours. The powders were then densified using Dr. Sinter SPS 625 under vacuum conditions below 10 Pa, compaction pressure of 40 MPa, and a heating rate of 100 °C/min (0 – 600 °C) and 20 °C/min (600 – 1150 °C). The results indicate that the powder milling affects the crystallite size, sintering behavior, and hardness of WC-12Co. The crystallite size of WC-12Co powder is reduced from 68.8 nm to 32.1 nm after milling. This results in a slight decrease in sintering temperature and an increase in the density and hardness of the sintered alloy. The further comparative results are intensively discussed in this paper.
