AbstractKnowledge of the three‐dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three‐dimensional swimming behavior of small mesopelagic fishes in situ. We explore a 4‐month continuous dataset containing more than 100,000 nocturnal tracks of juvenile Maurolicus muelleri, obtained from a surface‐facing, moored echosounder in a Norwegian fjord. We extend previous observations of vertical nocturnal swimming and step‐wise (stop‐and‐go) dusk and dawn migrations with the corresponding horizontal and turning behavior. In the middle of the night, the M. muelleri mainly drifted with the currents. Horizontal swimming speeds were then usually below 0.5 body length s−1 but increased substantially during the step‐wise dusk and dawn vertical migration. Most vertical relocations were followed by a change in horizontal direction. Our observations are in line with hypotheses of growth maximization in the juvenile fish, and of reducing detection and encounters with predators.

AbstractBackgroundRecently, patient rotating devices for gantry‐free radiotherapy, a new approach to implement external beam radiotherapy, have been introduced. When a patient is rotated in the horizontal position, gravity causes anatomic deformation. For treatment planning, one feasible method is to acquire simulation images at different horizontal rotation angles.PurposeThis study aimed to investigate the feasibility of synthesizing magnetic resonance (MR) images at patient rotation angles of 180° (prone position) and 90° (lateral position) from those at a rotation angle of 0° (supine position) using deep learning.MethodsThis study included 23 healthy male volunteers. They underwent MR imaging (MRI) in the supine position and then in the prone (23 volunteers) and lateral (16 volunteers) positions. T1‐weighted fast spin echo was performed for all positions with the same parameters. Two two‐dimensional deep learning networks, pix2pix generative adversarial network (pix2pix GAN) and CycleGAN, were developed for synthesizing MR images in the prone and lateral positions from those in the supine position, respectively. For the evaluation of the models, leave‐one‐out cross‐validation was performed. The mean absolute error (MAE), Dice similarity coefficient (DSC), and Hausdorff distance (HD) were used to determine the agreement between the prediction and ground truth for the entire body and four specific organs.ResultsFor pix2pix GAN, the synthesized images were visually bad, and no quantitative evaluation was performed. The quantitative evaluation metrics of the body outlines calculated for the synthesized prone and lateral images using CycleGAN were as follows: MAE, 35.63 ± 3.98 and 40.45 ± 5.83, respectively; DSC, 0.97 ± 0.01 and 0.94 ± 0.01, respectively; and HD (in pixels), 16.74 ± 3.55 and 31.69 ± 12.03, respectively. The quantitative metrics of the bladder and prostate performed were also promising for both the prone and lateral images, with mean values >0.90 in DSC (p > 0.05). The mean DSC and HD values of the bilateral femur for the prone images were 0.96 and 3.63 (in pixels), respectively, and 0.78 and 12.65 (in pixels) for the lateral images, respectively (p < 0.05).ConclusionsThe CycleGAN could synthesize the MRI at lateral and prone positions using images at supine position, and it could benefit gantry‐free radiation therapy.
Cooperative relay pursuit with input saturation constraint and external disturbances
Authors: Du Shengli , Zhu Lijun , Han Honggui , Qiao Junfei 
Published: September 2022

AbstractThis paper studies a class of tracking consensus problem called the cooperative relay pursuit where a group of agents cooperatively pursuit and capture an evading agent that enters the surveillance region. A subgroup of agents closest to the evader is commanded to pursuit the evader and thus called pursuers, while others called surveillance agents stay at their origin places. A relay mechanism is introduced to respect the pursuit efficiency, energy constraints and other factors. As the evader moves, some pursuers that do not remain the closest vicinity of the evader leave the pursuing group, while some surveillance agents that become more closer to the evader join into the pursuing. Due to the relay mechanism, the dynamics of pursuers are naturally an impulsive system and thus is nonsmooth. This paper aims to propose a distributed controller to achieve cooperative relay pursuit even when agents are subjected to both input saturation constraint and external disturbances. A modified algebraic Riccati equation and low‐gain technique are proposed to achieve the tracking consensus with an performance. A simulation example is provided to validate the theoretical results.

Published: September 2022

AbstractThis article investigates the robust control invariance and robust set stabilization problems based on a semi‐tensor product method for a class of mix‐valued logical control networks (MVLCNs) with disturbances. First, a calculation method for the largest robust control invariant subset contained in a given set is proposed. Second, based on the robust control invariant subset, the robust set stabilization of MVLCNs is discussed, and new results are presented. Furthermore, the design algorithm of time‐optimal state feedback stabilizers via antecedence solution technique is derived. The study of an illustrative example shows the effectiveness of the obtained new results.

Published: September 2022

AbstractMicroarchitectures with complex interior structures are important for many applications. However, engineering complex interior structures within microarchitectures are challenging. This article reports the introduction of electrochemical sculpting processes to carve the microarchitectures during or after their electrochemical growing process to design the interior structure of the microarchitectures. The electrochemical growing and sculpting process tangle together under the constant voltage electrodeposition mode with their strength depending on the ion concentration gradient and the voltage value. The unique thawing process of the frozen electrolyte is used to create the desired sharp ion concentration gradient, and has the potential to control the strength of the sculpting and the growing processes. How to completely decouple the growing and the sculpting process is further studied to gain more accurate control over the interior structures of the microarchitectures. It is revealed that the sculpting process can be exclusively applied onto the electrochemically grown microarchitectures simply by reversing the electric field without triggering any growing processes. Microarchitectures with complex interior structures, including micropyramids with a single cavity exclusively at the outward or every apex to multi‐walled hollow pyramids with designable wall numbers and inter‐wall distances are prepared as examples.

AbstractFachwerkkonstruktionen aus direkt verschweißten Hohlprofilen unter vorwiegend ruhender Beanspruchung werden in vielen Bereichen des Stahlhochbaus und der Infrastruktur, wie bei Fußgängerbrücken, sowie im Anlagen‐ oder Mobilkranbau eingesetzt. Die Verwendung hochfester Stähle ermöglicht bei hohen Tragfähigkeitsanforderungen und großen Spannweiten eine materialsparende Bauweise. Zur Ausnutzung dieses Potenzials sind Bemessungsregeln erforderlich, die die spezifischen Eigenschaften dieser Stähle zutreffend erfassen. Die derzeit gültigen Bemessungsregeln für Hohlprofilanschlüsse wurden anhand von Versuchen mit normalfesten Stählen auf semiempirische Weise hergeleitet. Im Rahmen dieser Versuche zeigte sich, dass durch Plastizieren lokale Spannungsspitzen abgebaut und sekundäre Biegemomente umgelagert werden. Im Unterschied zu normalfesten Stählen weisen hochfeste Stähle ein geringeres plastisches Umlagerungsvermögen auf. Dem wird in den Bemessungsregeln derzeit durch pauschale, abgeschätzte Abminderungsfaktoren Rechnung getragen, die für hochfeste Hohlprofile bislang nicht ausreichend experimentell validiert wurden. Durch die Projekte zu den „Hochfesten Hohlprofilknoten“ im FOSTA Forschungsverbund HOCHFEST sollen differenzierte und abgesicherte Bemessungsregeln hergeleitet werden, die einen wirtschaftlichen und ressourcenschonenden Einsatz hochfester Stähle in Hohlprofilkonstruktionen ermöglichen.

AbstractA series of five M(II) silylamide complexes [M{Me2Si(NPh)2}(iPr2Im)2] (M=Cr, Mn, Fe, Co, Zn), iPr2Im=1,3‐diisopropylimidazoline‐2‐ylidene) were synthesized and characterized by spectroscopic methods and single crystal X‐ray analyses. The Cr(II) complex [Cr{Me2Si(NPh)2}(iPr2Im)2] exhibits a distorted square planar coordination from a chelating Me2Si(NPh)2 group and two NHC ligands. In the case of the Mn, Fe, Co and Zn derivatives the coordination mode is distorted tetrahedral. With exception of the Zn complex all derivatives are paramagnetic with μeff. values of 4.71 B.M. (Cr), 5.08 B.M. (Fe), 5.91 B.M. (Mn) and 3.94 B.M. (Co).

Published: September 2022

Abstract
Background
Hand injuries compose up to 30% of all injuries in emergency care. However, there is a lack of epidemiological data reflecting patient or accident-related variables, injury types, injured anatomical structures or trauma localization.

Objective
The objective of this study is (1) to provide epidemiological information on hand injuries and their patterns and (2) to visualise the frequencies of affected areas of the hand in relation to the most common trauma mechanisms using color-coded heatmaps.

Methods
This prospective single-center observational trial conducted at a surgical emergency department in Germany collected data of hand trauma patients using a standardized documentation form. Demographic data, trauma-related data, diagnostic and therapeutic measures were analyzed. Color-coded heatmaps were generated marking anatomic danger zones.

Results
435 patients with a mean age of 39.5 were included. Most patients admitted on their own initiative (79%). Leisure and sport injuries were most frequent (75%). Digiti II–V were injured most commonly (43%), followed by metacarpals (19%) and the thumb (14%). Blunt trauma and cuts accounted for most injuries (74%). Hand-graphics depicted color-coded frequencies of the affected areas of the palmar and dorsal aspect of the hand for the most common types of injury, as well as the most frequent circumstances of accident. Elective surgery was recommended in 25% of cases, and hand surgical follow-up was proposed in over 50% of cases.

Conclusions
The dorsal aspect of the hand including the 5th metacarpal, the radial wrist and thenar region, as well as the fingertips of Digiti II/III represent anatomic danger zones to injury of the hand. Due to the large variety of potentially injured structures, diagnosis and treatment is not trivial. Specific training is required for all surgical specialties in emergency care, to increase quality of diagnostic work-up and management of hand injuries.

Published: September 2022

Summary
Background
The incidence and the comorbidities, such as infectious diseases (e.g. pneumonia or influenza) of diabetes mellitus are increasing. Therefore, the purpose of this study is to investigate immunization status and preventive care in diabetes mellitus patients.

Methods
Two groups from the Austrian health interview survey 2014 were identified, a cohort of diabetes mellitus (DM) individuals (n = 678) and a non-diabetes mellitus (non-DM) cohort (n = 15,093). The frequencies of doctors’ visits, preventive care and immunization status were compared. Furthermore, the study population was divided by age (> 50 years, < 50 years) and differences between > 50 years old DM with < 50 years old DM and the > 50 years old DM and > 50 years old Non-DM cohort were investigated.

Results
In the DM cohort a higher frequency of influenza immunization (13.3% vs. 7.1%, p < 0.001), doctor visits (89.4% vs. 75.4%, p < 0.001), and preventive care, such as colonoscopy (11.2% vs. 6.8%, p < 0.001) and hemoccult tests (32.6% vs. 22.1%, p < 0.001) was observed. Even though older DM individuals have a higher risk for complications, the > 50 years DM cohort has similar frequencies of colonoscopy, hemoccult test and immunization against influenza and TBE (tick-borne encephalitis) compared to > 50 years Non-DM. Although the > 50 years old DM cohort had a higher frequency of doctors’ visits, they still had lower frequencies of mammography and dentists’ visits compared to > 50 years old Non-DM. In comparison to the < 50 years old DM cohort, the > 50 years DM cohort was related to lower intact immunization status of tetanus, diphtheria, Polio and TBE. Still a higher frequency of intact immunization of pneumococcus, influenza and doctors’ visits in the > 50 years old DM cohort compared to the < 50 years old DM cohort can be reported.

Conclusion
Preventive care and immunization status in the DM cohort just differ slightly from the general cohort but still should be improved.
CCL24/CCR3 axis plays a central role in angiotensin II–induced heart failure by stimulating M2 macrophage polarization and fibroblast activation

Published: September 2022

Abstract

Aims

We aimed to investigate the effect and mechanism of pleiotropic chemokine CCL24 in heart failure.

Methods and results

Compared with normal donators, the expression of CCL24 and number of cardiac M2 macrophages in heart were higher in heart failure patients, the same as plasma CCL24. Treatment with CCL24 antibody hindered Ang II (1500 ng/kg/min)–induced cardiac adverse remodeling through preventing cardiac hypertrophy and fibrosis. RNA-seq showed that CCL24/CCR3 axis was involved in immune and inflammatory responses. Single-cell analysis of cytometry by time of flight (CyTOF) revealed that CCL24 antibody decreased the M2 macrophage and monocyte polarization during Ang II stimulation. Immunofluorescence co-localization analysis confirmed the expression of CCR3 in macrophage and fibroblasts. Then, in vitro experiments confirmed that CCL24/CCR3 axis was also involved in cardiac primary fibroblast activation through its G protein–coupled receptor function.

Conclusion
CCL24/CCR3 axis plays a crucial part in cardiac remodeling by stimulating M2 macrophage polarization and cardiac fibroblast activation.

Graphical abstract
Cardiac M2 macrophages, CCL24 and circulation CCL24 increased in heart failure patients. Treatment with CCL24 Ab hindered Ang II induced cardiac structural dysfunction and electrical remodeling. In CCL24 Ab group RNA-seq found that it was related to immune responses and hypertrophic cardiomyopathy, CytoF revealed M2 macrophages and monocytes decreased obviously. In vitro,CCL24 promoted activation and migration of cardiac fibroblast.

Published: September 2022

AbstractThe ability of early hominins to overcome the constraints imposed by the characteristics of raw materials used for stone tool production is a key topic on the discussion about the evolution of hominin cognitive capabilities and technical behaviours. Thus, technological variability has been the centrepiece on this debate. However, the variability of lithic assemblages cannot be correctly interpreted without understanding site occupational models and function and considering that individual tools represent specific discard moments in a continuous reduction process. In Europe, the earliest technological record is represented by the scarce and scattered Mode 1 technologies, often deriving from occasional occupations or restricted activity areas yielding unrepresentative assemblages. In this paper, we approach the technological behaviours exhibited by Lower Palaeolithic hominins from the subunit TD6.2 of the Gran Dolina site (Atapuerca, Burgos) by including the perspective of reduction intensity studies on the analysis of technological variability. Gran Dolina TD6.2 is a unique and extremely significant archaeological context, as it represents the oldest multi-layered unit of domestic hominin occupations in the Early Pleistocene of Europe. We use the Volumetric Reconstruction Method (VRM) to estimate the original volume of the blanks and quantify the reduction intensity of each core individually to characterise the reduction distribution patterns using Weibull probability distribution functions. Our results suggest differential raw material management in terms of reduction intensity, according to the characteristics of each lithology. This could reflect a solid understanding of raw material qualities and a certain degree of planning. Altogether, the continuity between knapping strategies through reduction denotes constant adaptation to raw material constraints as well as particular knapping conditions, rather than specific compartmentalised mental schemes. In conclusion,Homo antecessortoolmakers would have been situational knappers whose technological behaviour would be highly adaptive. This research constitutes the first reduction approach for the European Early Pleistocene assemblages that will lead to a referential framework for other European Early Pleistocene sites.

AbstractIn the framework of the project RemoteALPHA, an optical scanning system for remote sensing of alpha emitters using radioluminescence is being developed. After the feasibility of the technique was proven, current work aims at improving the sensitivity for detection of low surface activities. As calibration standard, pitchblende minerals were prepared. Their surface count rate of 80 Bq cm-2 to 105 Bq cm-2 was measured by alpha-track-detection and alpha-spectroscopy. Subsequently, radioluminescence measurements were performed in a sealed chamber filled with different gas atmospheres. The radioluminescence signal was measured in UVC and UVA spectral ranges for all samples.
