Abstract
According to the current situation of China's agricultural picking, large scale, complex terrain and labor shortage. This design is an all-terrain intelligent agricultural picking robot. The picking robot has the functions of walking, avoiding obstacles and picking. In this paper, the design of robot structure and hardware circuit control is carried out. The basic structure of the design is divided into upper box and lower box. The upper box is a replaceable functional device and the default is a cargo hold and picking robot arm. The lower box is composed of a new all-terrain track motion mechanism and camera module, obstacle avoidance module, power module, transmission module and core control module. The upper box is fixed by a detachable bolt group on the balance table of the lower box, and the mechanical arm is installed in the cargo hold through bolt connection. The end of the mechanical arm is loaded with a pressure sensor, and the new all-terrain track motion mechanism and the drive and sensing control system equipped with the lower box can realize the picking and handling of the operation object. Aiming at the climbing stability, the dynamic modeling was carried out and the maximum climbing height of the robot was obtained based on theoretical calculation and simulation. Through the finite element analysis of the main parts of this design, it is found that the strength meets the requirements of material properties and the calculation is reasonable and reliable. The design has the advantages of stable structure, easy implementation and operation, low cost, strong expansibility and practicability, and easy promotion and application. It can be used with harvesting machinery, spraying equipment, etc., and can also be put into rescue and disaster relief, scientific research and exploration, logistics and transportation and other fields.

Published: January 2025

Abstract
To keep GIS (Gas Insulated Substations) bus bar device safe from long distance transportation, EVA (ethylene–vinyl acetate copolymer) plastic support is used as buffer. Creep caused by long-term pressure during ocean carriage should be taken into consideration to avoid structural damage. This paper develops a process to combines the FEA (finite element analysis) result calculated by ABAQUS and numerical iteration to predict the large creep deflection of the EVA plastic support. Result shows that the theory can predict a more accurate process of creep behavior and a purely numerical guide is built for assessment at packaging site.

Published: January 2025

Abstract
The aerodynamic forces acting on the surface of the turbine rotor blades are the main factor to affect their vibration characteristics, and the resonance of rotor blades can be determined and forced response analysis can be carried out based on the characteristics of aerodynamic excitation force. In the paper, the equivalent aerodynamic excitation forces on the surface of the rotor blade of a certain aeroengine blisk structure are extracted and analyzed, and then the frequency distribution of the excitation force and its variation with rotating speed are analyzed in the time and frequency domains. The results show that the main component of the aerodynamic force is the mean value and the dangerous excitation order is one and two times of the stator blade number. It can be used in forced response analysis to determine the resonance and high cycle fatigue.

Research on Control Strategies of Anti-surge Systems for Large Centrifugal Fans
Authors: Wu Zijing , Tian Hai , Li Chao , Wang Saisai , Tao Zhen 
Published: January 2025

Abstract
The occurrence of surge in large centrifugal fans during operation can lead to a degradation of their original operational quality, resulting in substantial economic losses and even posing serious safety hazards. In this study, we propose a constant-pressure approach to approximate the surge limit line, addressing the limitations of fixed and variable surge limit methods when the flow approaches the surge limit. This control strategy effectively expands the stable operating region of large centrifugal fans, enhancing their operational efficiency. Additionally, we employ a Radial Basis Function Neural Network (RBFNN) optimized PID controller for controlling the opening of the recirculation valve. Through this approach, dynamic response and control accuracy are significantly improved. Matlab/Simulink simulations demonstrate that the RBFNN-PID controller achieves the shortest settling time, minimal overshoot, rapid response, and excellent control precision and stability.
Performance Analysis of AlGaN/GaN MOS-HEMT Based Biosensors
Authors: Liu Yue , Ma Yuzhen , Guo Haiqui , Liu Yanli 
Published: January 2025

Abstract
The sensing performance of AlGaN/GaN MOS-HEMT biosensors for neutral biomolecules was investigated by Silvaco TCAD. In order to achieve excellent sensing sensitivity, the gate length (1–4 µm) and AlGaN barrier layer thickness (10–30 nm) of the MOS-HEMT were optimized. The results show that by keeping the sensing area constant, the sensing performance of MOS-HEMT decreases with the increase of the gate length. However, the sensing sensitivity increases with the increase of gate length by keeping the gate dielectric length at 0.5 µm. Moreover, the trend of ∆IDS change slows down as the gate length increases. In addition, the relatively thinner AlGaN barrier layer can optimize the sensing performance of the MOS-HEMT biosensor. Ultimately, the optimal sensitivity was obtained of MOS-HEMT with a 1.5-µm-long gate and 10-nm-thick AlGaN barrier layer. For casein biomolecules, the ∆IDS of MOS-HEMT is 196.8 mA/mm. This study offers crucial validation for the advancement of GaN-based MOS-HEMT biosensors, significantly contributing to the field’s progress.
Retrospektive Analyse von Kindern mit Impfgranulomen
Authors: Trefzer Laura , Kerl-French Katrin , Weins Andreas Benedikt , Schnopp Christina 
Published: January 2025

Zusammenfassung

Hintergrund
Impfgranulome sind eine häufige (0,3–1 %), unerwünschte Wirkung von (akzidentell) subkutan verabreichten Impfungen und spezifischen Immuntherapien, die aluminiumhaltige Konjugate enthalten. Die klinische Symptomatik aus juckenden subkutanen Knoten betrifft überwiegend Säuglinge und Kleinkinder an den lateralen Oberschenkeln.

Ziel der Arbeit
Ziel ist es, Dermatologen zu sensibilisieren, diese häufige und harmlose Impfreaktion zu erkennen, um invasive Diagnostik und Verunsicherung von Eltern und Behandlern zu verhindern.

Material und Methoden
Es erfolgen eine retrospektive Analyse von 13 Kindern, die zwischen 2019 und 2023 in der kinderdermatologischen Sprechstunde vorstellig waren, sowie die Herausstellung von Diagnosekriterien und praktischem Handlungsleitfaden unter Einbeziehung der Literatur.

Ergebnisse und Diskussion
Es wurden 13 Kinder (9 Jungen, 4 Mädchen) mit subkutanen indolenten, juckenden Knoten an den Impflokalisationen (11 an Oberschenkeln, 2 an den Oberarmen), die mit einer zeitlichen Latenz von Wochen bis Monaten auftraten, retrospektiv ausgewertet. Die Impfung der Kinder war nach STIKO(Ständige Impfkommission)-Empfehlung erfolgt. Das dokumentierte Auftreten der ersten Impfgranulome war zwischen dem 12. und 36. Lebensmonat (LM). Die 3. Grundimmunisierung der hexavalenten Totimpfung fällt im STIKO-Impfkalender mit der ersten Gabe des Lebendimpfstoffes MMR(Mumps, Masern, Röteln)(‑Varizellen [V]) zusammen (ab 11. LM). Fälschlicherweise kann dies zu der Annahme führen, dass der Lebendimpfstoff ursächlich für die Granulomentwicklung war. Die Aluminiumkonjugation von Totimpfstoffen scheint ein zentraler Auslöser der Granulome zu sein, weitere Suszeptibilitätsfaktoren sind nur unvollständig bekannt. Der Nachweis einer Sensibilisierung auf Aluminium im Epikutantest bringt keinen Zusatznutzen und sollte daher nicht standardmäßig durchgeführt werden. Nach Wochen bis Jahren kommt es zur spontanen Regredienz der Granulome.

Material and social deprivation among one-person households: the role of gender
Authors: Fabrizi Enrico , Mussida Chiara , Parisi Maria Laura 
Published: January 2025

Abstract
We explore whether gender has a statistically significant impact on material and social deprivation of single adults after accounting for other characteristics. We use data from the 2022 European Union Statistics on Income and Living Conditions survey for six European countries. By assuming deprivation as an individual latent trait and by treating different deprivation levels as ranked categories, we estimate a proportional odds model separately by country. Our findings suggest a clear role for gender, i.e., the risk of being materially and socially deprived is relatively higher for women everywhere. The novelty is that facing “unexpected expenses” is the worst trouble for women, clearly coming from relative financial and economic fragility. Individual characteristics play a more important role than more aggregate indicators at explaining the risk of material and social deprivation. Finally, the estimated gender gap is robust to a large set of changes in model specification and assumptions.

Abstract
The “obesity paradox” suggests that, despite a higher baseline risk for adverse health outcomes, obese patients can experience a lower complication and mortality rate in conditions such as pulmonary embolisms (PE). This study aims to examine the association between obesity and inpatient outcomes of PE patients, utilizing the data from the National Inpatient Sample (NIS) database. We conducted a retrospective study analysis of obese adult PE patients (aged ≥ 18) using the NIS database from 2016 to 2020. Patients were categorized as either obese (body mass index (BMI) ≥ 30) or non-obese, excluding those with cancer diagnosis and age > 75 years to reduce confounding factors. Multivariable logistic regression, adjusted for confounders, compared the inpatient outcomes, including mortality, length of stay, need for mechanical invasive ventilation (MIV), incidence of shock requiring vasopressor use and use of reperfusion therapies. Our results showed obese patients had a lower in-hospital mortality and reduced risk for certain adverse outcomes when compared to non-obese patients. Limitations in our data, such as the lack of imaging confirmation and inability to track certain risk indicators in real time, affected precision in outcome severity classification. Our findings support the existence of an obesity paradox, particularly in PE patients, with obese patients experiencing better inpatient outcomes relative to their non-obese counterparts. This study advances the understanding of obesity’s complex role in PE outcomes. However, further research is needed to further elucidate potential protective mechanisms to address our study limitations.

Published: January 2025

Abstract

Background
The application of international recommendations for paediatric maintenance haemodialysis (HD) could be strengthened by national laws or written recommendations. Our aim was therefore to describe the national rules governing paediatric maintenance HD in European countries.

Methods
A national representative, approved by the president of each paediatric nephrology society, was contacted in all 42 European countries to complete two online questionnaires.

Results
Answers were received from 36 countries. The population served by HD centres varies from 83,000 to 1,197,000 residents below 18 years of age and the estimated mean number of children on HD per centre from 0.2 to 13.5. The lowest age at which a child can be dialysed in an adult centre varies from 0 to 18 years. Laws or written national recommendations specifying: this age, the need for a paediatrician as part of medical team in mixed adult–paediatric centres, the minimum number of doctors per centre and the number of patients per nurse or nurse’s aide required during sessions exist in only 25, 22, 22, 44 and 8% of the countries, respectively. Similarly, dietitians, social workers, school service, psychologists and play specialists/youth workers are required by law or written national recommendations in 36, 28, 36, 31 and 14% of countries, respectively.

Conclusion
Laws or written national recommendations for paediatric maintenance HD are rare in European countries and very heterogeneous when they exist. This calls for discussion among paediatric and adult nephrologists and health authorities on the organisation of safe and effective paediatric HD practices.

Der Cluster Headache Impact Questionnaire
Authors: Kamm Katharina , Straube Andreas , Ruscheweyh Ruth 
Published: January 2025

Zusammenfassung
Der Clusterkopfschmerz ist eine schwere primäre Kopfschmerzerkrankung, die mit einer erheblichen Beeinträchtigung für die Betroffenen einhergehen kann. Der Cluster Headache Impact Questionnaire (CHIQ) ist ein kurzer Fragebogen zur Erfassung der Clusterkopfschmerz-spezifischen Beeinträchtigung. Eine fünfstufige Schweregradeinteilung von „keine oder leichte Beeinträchtigung“ bis „extreme Beeinträchtigung“ wurde auf der Grundlage der Ergebnisse eines englischsprachigen Patientenkollektivs festgelegt. In der vorliegenden Veröffentlichung wurde untersucht, ob sich diese Schweregradeinteilung auf eine deutsche Kohorte übertragen lässt. Dazu wurden Daten von 196 PatientInnen mit chronischem und episodischem Clusterkopfschmerz während einer aktiven Episode untersucht. Die Schweregradeinteilung des CHIQ zeigt auch im deutschen Patientenkollektiv klinisch sinnvolle Ergebnisse; so unterschieden sich die 5 Schweregrade signifikant in Bezug auf Attackenhäufigkeit, Einnahme von Akutmedikation, unspezifische kopfschmerzbezogene Beeinträchtigung (HIT-6) und Lebensqualität (SF-12v2). Interessanterweise gaben 32 der 52 PatientInnen mit episodischem Clusterkopfschmerz außerhalb der aktiven Episode eine Beeinträchtigung oberhalb des untersten Schweregrads an, also eine mindestens mäßiggradige Beeinträchtigung. Zusammenfassend bietet der CHIQ ein kurzes Instrument zur Erfassung der aktuellen Beeinträchtigung bei Clusterkopfschmerz. Die klinische Interpretation wird durch die hier vorgestellte Schweregradeinteilung erleichtert.

Protocol for the AFTERHERNIA Project: patient-reported outcomes of groin and ventral hernia repair
Authors: Gram-Hanssen Anders , Baker Jason Joe , Reistrup Hugin , Andersen Klaus Kaae , Rosenberg Jacob 
Published: January 2025

Abstract

Purpose
The AFTERHERNIA Project aims to shift the focus of hernia surgery towards patient-reported outcomes by examining the impact of surgical methods and long-term complications on a national level. Groin and ventral hernia repairs are common surgical procedures with significant impact on patient quality of life and healthcare costs. Most large-scale studies focus on clinical outcomes like reoperation and readmission rates, rather than patient-reported outcomes.

Methods
This nationwide survey involves Danish patients who have undergone groin or ventral hernia repair over a ten-year period. Patients will be identified in the Danish National Patient Registry, and they will receive either the Abdominal Hernia-Q or Groin Hernia-Q questionnaire to collect data on patient-reported outcomes. Data from the questionnaire will be linked with clinical and patient-related data from the Danish Hernia Database. The Danish National Patient Registry also contains information on long-term surgical complications. Thereby, it will be possible to link specific perioperative details with patient-reported outcomes and long-term surgical complications.

Conclusion
The AFTERHERNIA Project aims to redefine the understanding of hernia surgery outcomes by emphasizing patient-reported outcomes on a nationwide basis. By capturing a broad spectrum of patient experiences and outcomes, the project expects to inform and possibly transform clinical guidelines and patient care practices.

Abstract
This review article series on water and electrolyte disorders is based on the ‘Electrolyte Winter Seminar’ held annually for young nephrologists in Japan. The seminar features dynamic case-based discussions, some of which are included as self-assessment questions in this series. The second article in this series focuses on treatment of hyponatremia, a common water and electrolyte disorder frequently encountered in clinical practice. Hyponatremia presents diagnostic challenges due to its various etiologies and the presence of co-morbidities that affect water and electrolyte homeostasis. Furthermore, limited evidence, including a lack of robust randomized controlled trials, complicates treatment decisions and increases the risk of poor outcomes from inappropriate management of both acute and chronic hyponatremia. This review provides a comprehensive overview of treatment of hyponatremia for better comprehension and improved clinical practice.

Abstract
The disruption of vehicle traffic on important transport infrastructure has a major economic impact. Therefore, the instability of highway cut-slopes poses a significant risk for major infrastructures crossing mountainous regions and rocky coasts. The use of Uncrewed Aerial Vehicles (UAVs) is of great help in the prevention of road cut-slope failures and in emergency and rehabilitation of sites impacted by this type of landslides. Here, we show an example of UAV operations in emergency response and recovery in a highway cut-slope failure. We analyzed a failure that occurred on 11 March 2021 in a 52-m-high cut-slope located at 354.3 km of the A-7 Highway (S Spain). We also examine the applications of these analyses to help in risk evaluation and management. We acquired 3050 images and 6 videos with UAVs during 5 field surveys from 11 to 31 March 2021 to follow the evolution of the destabilized cut-slope. The videos taken by UAVs were of great help in the emergency response phase to guide the first steps in the removal of unstable rock blocks. The acquired images served to generate sequential Digital Elevation Models (DEMs) and 3D models (i.e., point clouds and tiled models) using the Digital Photogrammetry technique. These models were used subsequently to identify changes in the topography and calculate volumes of both destabilized and excavated material. The volumetric analyses indicate that 6200 m3 of rock collapsed, producing a deposit of debris of 10,900 m3, and after the partial failure, 15,100 m3 of the slope remained unstable. Therefore, the volume of rock mobilized by the landslide was about 21,300 m3. The recovery activities involved the removal of the collapsed debris and the re-profiling of the slope. This involved the excavation, transportation, and deposition of 83,400 m3 of rock to reduce the slope’s inclination from 64° to 45–33°. We then analyzed the follow-up work generating sequential DEMs during the cut-slope excavation in order to forecast the approximate date of the highway reopening. Thus, an average excavation speed of 1075 m3/day was estimated, and with this value, by March 31, it was possible to initially forecast that the highway could be reopened in the first week of June, not far from June 10, the date on which it was finally reopened. These results were obtained with reduced equipment costs and field time over topography conventional methods, which indicates the usefulness of UAVs and Digital Photogrammetry (UAV-DP) in emergency response and recovery situations provoked by unstable slopes in roads.
