Small‐Signal Synchronization Stability Enhancement of GFL‐Based Renewable Energy Generation Using the Koopman Operator
Authors: Zheng Le , Zheng Jiajie , Liu Xin , Li Gengyin , Xu Yanhui 
Published: February 2025

ABSTRACTRecent reports have highlighted small‐signal synchronous instability issues in grid‐following converter‐based renewable energy generation systems connected to weak power grids. This study introduces a Koopman operator‐based approach for system state prediction and small‐signal synchronization stability enhancement through a data‐driven strategy. Initially, system dynamics are identified and forecasted using measured data via delay embedding and the Koopman operator, effectively transforming the original nonlinear system dynamics into a more manageable linear framework in a higher‐dimensional space. Subsequently, a supplementary control loop is implemented, and control variables are calculated employing model predictive control within the elevated Koopman space. This proposed technique is independent of the ‘white box’ model structure and parameters, thereby offering adaptability to changes in operational conditions. The effectiveness of this method has been confirmed through case studies conducted on a modified IEEE 39‐bus system, demonstrating its viability.

AbstractThrombocytopenia at admission predicts mortality in multiple myeloma (MM) and might link to disease progression. Although thrombocytopenia is known to be associated with MM, a possible thrombopathy is clinically less known. We conducted a case–control study comparing platelet responses of MM patients to controls via flow cytometry, integrin αIIbβ3 activation and P-selectin exposure, and a bioluminescent assay, ATP release. No difference was found at baseline, but upon platelet stimulation, MM patients had decreased αIIbβ3 activation, partly impaired P-selectin exposure, and reduced δ-granule (ATP) secretion. Aspirin treatment in patients did not account for these diminished platelet responses. In total, 29% of patients had thrombocytopenia, while 60% had decreased αIIbβ3 activation and 67% had reduced platelet secretion capacity. Importantly, as secretion capacity was corrected for platelet count, granule release per platelet was reduced in patients versus controls. Of 6 patients with thrombocytopenia 4 displayed a thrombopathy, while for 15 patients with normal count, 64% had reduced αIIbβ3 activation and 73% had reduced platelet secretion capacity. Of all patients, 10% had thrombocytopenia combined with reduced αIIbβ3 activation plus low secretion capacity (one patient showed no qualitative or quantitative platelet defect). Our data suggest that beyond the known thrombocytopenia, MM patients also have reduced platelet function, which could reflect impaired platelet vitality. Combined measurement of platelet count and function, especially secretion capacity, gives a more comprehensive view of platelet phenotype than count alone. Large prospective follow-up studies are needed to confirm the importance of the acquired platelet secretion defect on the prognosis of MM patients.

Parotisbefund löst Rätsel um „Erkältung“
Authors: Jahn Claus 
Published: February 2025

SummaryEine typische „Erkältung“ mit Sinusitis, die später das Bild einer Allergie annahm, entpuppte sich im vorgestellten Fall schließlich als Sjögren-Syndrom – eine Autoimmunerkrankung, die vor allem die Speichel- und Tränendrüsen betrifft. Die betroffene Patientin zeigte neben der typischen Augen- und Mundtrockenheit entzündete Atemwegsschleimhäute, Müdigkeit und Gelenkschmerzen, worauf im Serum spezifische Antikörper sowie leicht erhöhte Entzündungsparameter gefunden wurden. Eine homöopathische und phytotherapeutische Therapie zur Immunmodulation und -suppression, Mund- und Augenbefeuchtung sowie eine antiinflammatorische Ernährung brachten eine deutliche Entlastung.
Qualitätsstandards der Infektiologie in der stationären Versorgung

Published: February 2025

ZusammenfassungNeben der seit längerem bestehenden einjährigen Zusatzweiterbildung für Infektiologie wurde vor kurzem in Deutschland die Facharztweiterbildung für Innere Medizin und Infektiologie eingeführt. Während für die Weiterbildung Curricula existieren, gibt es in Deutschland weder eine Beschreibung der genuin infektiologischen Tätigkeit, noch wurden bisher Standards hierfür definiert. Sowohl für die strukturelle Etablierung der Infektiologie in den Kliniken als auch für die Sicherung der Versorgungsqualität erscheint dies notwendig. Im vorliegenden Artikel werden deshalb Qualitätsanforderungen für infektiologische Kerntätigkeiten aufgeführt. Auch wenn kein eigener Schwerpunkt für Infektiologie in der Kinder- und Jugendmedizin deutschlandweit etabliert ist, sollten diese Prinzipien hier ebenfalls gelten.
Observations on the use of a bone chisel as a weapon using the
example of a Corded Ware double burial from Knittlingen,
Baden-Württemberg
Authors: Francken Michael , Kretschmer Inga 
Published: February 2025

AbstractSkull injuries, especially those caused by interpersonal violence, are not
uncommon in archaeological contexts. However, depending on the state of
preservation of the skeletal material, it can be difficult to determine the
cause of the injury. In the present case of a Corded Ware double burial from
Knittlingen (Baden-Württemberg, Germany), the analysis of a healed trepanation
and an unhealed blunt force trauma is relatively conclusive. However, due to the
dimensions of the injury, none of the customary weapons appear to be a suitable
candidate. For this reason, the hitherto ignored object group of bone chisels
was taken into focus and examined for its suitability as weapons. As a result,
the polished cutting edge in combination with the average muscular strength of
an adult seems indeed to be sufficient to cause fractures to the skull.
Nevertheless, it would be premature to interpret bone chisels from the Corded
Ware culture as weapons in general, as only the present case is known so far. It
therefore seems much more likely at present that in the case of Knittlingen a
bone chisel was used as an accidental weapon-tool.
Exploring Alternative Flaps in Endoscopic Skull Base Repair: A Comparative Cadaveric Study between Inferior Turbinate and Nasoseptal Flaps
Authors: Lee Kue Tylor , Brieck Kathryn , Hunyh Victoria N. , Bigler Diana , Haroun Kareem , Gelves Camilo Reyes 
Published: February 2025

Abstract
Introduction Over the past several decades expanded endonasal approaches have advanced significantly, paralleling the increasing importance of skull base defect reconstruction. The nasoseptal flap (NSF) is first line for most skull base reconstruction but may fail for complex or recurrent cerebrospinal fluid (CSF) leaks in central skull base. The inferior turbinate flap (ITF) presents an alternative due to proximity and robust vascular supply. This cadaveric study compares the NSF and ITF in central skull base repairs, detailing indications, limitations, and dimensions.
Methods We analyzed five cadaveric head specimens provided by the Medical College of Georgia Department of Anatomy. The NSF and ITF were raised bilaterally on each head, yielding 20 flaps in total. Length and width of each flap were measured, and total coverage area was calculated. SPSS (ver.20.0) was used for statistical analysis. Differences in mean width, length, and coverage area between the NSF and ITF were analyzed using Student's two-independent sample t-test, with p-values <0.05 considered statistically significant.
Results The NSF was significantly longer (64.6 mm) than ITF (42.8 mm), but the ITF was wider (46.6 mm) than NSF (36.5 mm). NSF had a larger mean coverage area (23.6 cm2) than ITF (19.9 cm2) (p = 0.053).
Conclusion While the NSF provides superior coverage, the ITF is a viable option in the reconstruction ladder for central skull base defects when NSF fails, offering advantages in terms of proximity, vascular supply, and lower morbidity over other rescue flaps. Surgical technique in harvesting this flap should be known to any skull base surgeon over other more complex reconstruction flaps.
Computed Tomographic Characteristics of Greyhound Central Tarsal Bone Fractures
Authors: Procter Rachel , Pearson Tim 
Published: February 2025

Abstract
Objective To characterize central tarsal bone fractures and associated tarsal fractures in a cohort of racing and ex-racing greyhounds using computed tomography (CT).
Study Design Retrospective observational study including 66 client-owned greyhounds (67 limbs) presented for central tarsal bone fracture between 2017 and 2024. Collected data included signalment, racing history, and laterality of tarsal injury. Central tarsal bone fractures were characterized using a previously described grading system, and concomitant tarsal injuries were recorded.
Results Of 67 central tarsal bone fractures, 59 showed moderate to severe comminution. Six fractures were dorsal slab fractures, one was a combined dorsal and medial slab fracture, and one was a luxation. Consistent with the findings of prior studies, the majority of central tarsal bone fractures affected the right limb (58/67 limbs). The most common concomitant tarsal injuries were fractures of the fourth tarsal bone (30/67 limbs), fractures of the calcaneus (25/67 limbs), and proximal intertarsal instability or luxation (6/67 limbs).
Conclusion CT reveals a substantially higher number of highly comminuted fractures than have been reported in prior studies that characterized central tarsal bone fractures using orthogonal radiography. Concurrent injury to other tarsal structures is a common finding and is an accurate predictor of severe comminution of the central tarsal bone.

Authors: Symma Nico , Hensel Andreas , Roether Bernd , Steinhoff Barbara , Bauer Rudolf 
Published: February 2025

AbstractThe workshop “Real-world data to document the use of phytopharmaceuticals in children” was organized by the GA Foundation Plants for Health in collaboration with multiple international scientific societies on July 14, 2024, during the International Congress on Natural Products Research in Kraków, Poland. The event focused on leveraging real-world data and real-world evidence to support the use of herbal medicinal products (syn. phytopharmaceuticals) in pediatric care. The workshop aimed to discuss the current state and future approaches for utilizing real-world data/real-world evidence in expanding the use of herbal medicinal products in children and adolescents. Therefore, the workshop highlighted the unmet needs and challenges in documenting the effectiveness and safety of herbal medicinal products in children and emphasized the coordinated exchange and collaboration among academia, industry, and regulatory authorities. After an e-symposium in May 2022 with more than 300
participants and an in-person workshop on this topic in Bonn in June 2023, this workshop in Krakow was the third event of its kind hosted by the Foundation Plants for Health. Participants concluded that interdisciplinary collaboration is highly needed to establish qualified methods of data collection and assessment of real-world data, e.g., establishing requirements to incorporate nonprescription herbal medicinal products into electronic patient records and registries that can be accessed by all stakeholders.

Abstract
Objective The aim of this study was to compare the technical difficulty and safety between right-sided percutaneous transhepatic biliary drainage (R-PTBD) and left-sided percutaneous transhepatic biliary drainage (L-PTBD) in patients with nondilated bile ducts.
Materials and Methods Forty-two patients (22 males and 20 females with a mean age of 46.2 ± 13.7 years) who received PTBD in nondilated bile ducts (from September 2021 to January 2024) were dichotomized into the R-PTBD (n = 22) and L-PTBD (n = 20) groups. The number of needle punctures, successful biliary punctures, technical success, difficulty in catheter placement, total fluoroscopic time, total procedure time, overall complications, and hemorrhagic complications were evaluated and compared between the groups.
Results The R-PTBD group had significantly fewer needle punctures for biliary access (3.9 ± 1.3 vs. 4.3 ± 1.3; p = 0.004) and a shorter procedure duration (21 ± 8.5 vs. 29.9 ± 13.2 minutes; p = 0.021) than the L-PTBD group. The successful biliary puncture (20 [90.9%] vs. 15 [75%]; p = 0.229) and technical success rate (20 [90.9%] vs. 14 [70%]; p = 0.123) were also higher for the R-PTBD group than for the L-PTBD group, while R-PTBD required less fluoroscopic time (5.83 [3.5–8.13] vs. 8.16 [4.34–12.9] minutes; p = 0.113). However, these differences did not reach statistical significance (p > 0.05). Further, difficulty during catheter placement was more frequently encountered in the L-PTBD group (02 [9%] vs. 04 [20%]; p = 0.367). The overall complication and hemorrhagic complication rates were comparable between both groups.
Conclusion When both approaches are equally suitable for patients with nondilated bile ducts, R-PTBD may be favored over L-PTBD, given the evidence demonstrating less technical difficulty in the right-sided approach than in the left-sided approach.

Authors: Shirodkar Kapil , Pilania Khushboo , Jankharia Bhavin G. , Botchu Rajesh 
Published: February 2025

AbstractIliopsoas bursitis, although not rare, may manifest clinically as a detectable mass in the groin area. This condition has the potential to apply pressure on the adjacent femoral neurovascular bundle, leading to isolated mononeuropathy.We present an uncommon case of femoral mononeuropathy in a 46-year-old female patient caused by an enlarged iliopsoas bursa. The case is noteworthy due to its rarity and the clinical and diagnostic challenges associated with assessing individuals with a groin mass, hip flexor weakness, and femoral nerve palsy.

Published: February 2025

Abstract
Background The superficial circumflex iliac artery perforator flap (SCIP flap) is an evolution of the conventional free groin flap. Even though the anatomical basis for SCIP flap is well established in general, the same is not described in a South Indian population.
Objectives The objectives of our study were to determine the anatomical variations of the superficial circumflex iliac artery perforators (SCIA perforators) and describe them in relation to the nearby bony landmarks like anterior superior iliac spine (ASIS) and pubic tubercle (PT).
Materials and Methods This observational study was done between October 2020 and December 2021. Cadaveric dissection was done and the required anatomic data were collected.
Results The mean diameter of SCIA was 0.99 mm and the mean pedicle length was 2.97 cm. The average diameters of the medial and lateral perforators were 0.63 and 0.55 mm, respectively. The pedicle lengths of the medial and lateral perforators were 3.03 and 4.31 cm, respectively. The medial perforator was 5.63 cm lateral and 1.66 cm superior to the PT. It was 5.37 cm medial and 5.99 cm inferior to the ASIS. The lateral perforator was 7.97 cm lateral and 2.73 cm superior to the PT. It was 2.86 cm medial and 4.11 cm inferior to the ASIS.
Conclusion Finding the exact location of the medial and the lateral perforators with respect to permanent bony landmarks and having an idea about their average pedicle length are useful for preoperative planning of the SCIP flap.

Abstract
Objective The aim of the study is to report the clinical outcomes of embolization for symptomatic varicoceles.
Materials and Methods In this institutional review board approved prospective study, 126 patients (median age: 30.58 ± 6.13 years) with 43 bilateral and 83 unilateral varicoceles were included. The majority of patients had pain as the major complaint, while 21 patients had associated infertility. The technical and clinical success and complications were studied.
Results The technical success was 100% (169/169 varicoceles). There was a significant reduction in the grading of varicocele on ultrasound postprocedure (p < 0.001). Ninety-eight percent had a reduction in their pain score. The preprocedural mean pain score was 6.4 ± 1.30, which decreased to 1.3 following the procedure. An overall satisfaction score of 9 of 10 was also noted. Out of 126 patients, 94.5% patients had uneventful recovery, while 7 patients had few minor complications. One patient had recurrence and received a repeat embolization.
Conclusion Embolization is safe and effective in the treatment of varicocele.
Enhanced power-line energy harvesting by capacitance compensation for remote self-powered CO2 monitoring
Authors: Qian Jieying , Xu Jiawen 
Published: February 2025

Aiming at carbon neutrality and compliance, it is necessary to monitor carbon emissions in remote areas. In this study, we proposed a remote self-powered CO2 monitoring system powered by a capacitance compensation enhanced power line energy harvester. The harvester consists of a magnetic core, a 4000-turn coil, and a matching capacitance. The coils would generate electrical energy due to the flux variation around the power lines. Besides, we demonstrate experimentally that the introduction of capacitance compensation would enhance the power output of the energy harvester and hence boost the overall efficiency of the system. Experimental studies of the proposed system revealed a capacitance compensation output power of 103.8 mW with a resistance load of 55 kΩ under 219 mArms current at 50 Hz. A microcontroller-based wireless sensor node was built for evaluation. The proposed system would ensure reliable remote CO2 monitoring mounted on power lines.
Longitudinal-lateral coupling control and global sensitivity analysis method for intelligent vehicles under heterogeneous disturbances

Published: February 2025

Abstract
Intelligent vehicles motion control system is a kind of nonlinear system with many het-erogeneous disturbances such as modeling inaccuracies, model coupling, parameters perturbation, speed fluctuation and external environmental disturbance. This paper ac-cordingly proposes a nonlinear longitudinal-lateral coupling model predictive control (LLMPC) method. Firstly, to effectively describe the inherent nonlinearity and coupling of the vehicle dynamic model, an approximate nonlinear longitudinal-lateral coupling model with a paradigm bounded uncertainty is established using linear fractional trans-formation (LFT) formulation. Secondly, a final-value theorem-based constrained feed-forward compensation strategy and a speed compensation are designed to obtain the longitudinal-lateral coupling control law, which can effectively handle heterogeneous disturbances of the system. Thirdly, a Sobol-based global sensitivity analysis method is designed to analyse and quantify the extent to which different disturbances affect the control performance of the system. Finally, the recursive feasibility of the closed-loop system is analysed and system asymptotic stability is proved through Lyapunov theorem. The simulation results of Carsim-Simulink and the statistical comparison analysis show the superiority of the proposed controller, which can effectively ensure the stability margin and has good tracking accuracy, robustness. Further, real-vehicle experimental results also show good accuracy and real-time performance.&#xD;
Transient measurement of the discharge termination field in an atmospheric pressure pulse discharge based on electric field induced second harmonic generation
Authors: Wang Xinyan , Yang Xin , Wang Wei , Lv Zepeng , Wu Kai 
Published: February 2025

Abstract
Motivated by the need for precise control of plasma parameters of atmospheric non-equilibrium plasma, we present an approach for the transient measurement of the electric field for discharge termination (i.e. the discharge termination fields, DTFs) based on the electric field induced second harmonic generation method. This approach utilizes a custom-designed electrode structure and introduces the integration system as the connection between the electric field and the response signals according to the superposition theorem of electric fields. Considering the electric field profile, the effect of the undesired electric field outside the copper foils on second harmonic generation is eliminated, leading to more accurate DTF measurement results. The DTFs for positive discharges decrease with increasing voltage amplitude or gap height, while the DTFs for negative discharges display the opposite trend, both of which are closely related to the discharge magnitude. Moreover, the higher measurement accuracy of the proposed method is further demonstrated in the experimental measurement of electric field evolution. The presented quantitative measurement results can be used to validate high-fidelity modeling predictions and facilitate a deeper understanding of the physical mechanisms of discharge extinction.
