Published: December 2024

AbstractStudies on the development of energy absorbing systems that minimize vehicle chassis damage in traffic accidents are increasing day by day. Many designs have been made in the studies on crushboxes used to absorb the energy released in the event of an accident. These design works are quite costly and take a long time. In this study, to design crushboxes faster and more economically was estimated using artificial neural network. The input layer of the artificial neural network model consists of three different materials, thicknesses (between 0.8 and 2.2 mm) and three different initial speeds. In the artificial neural network model, 42 different models were created by changing the different training functions (training, trainlm and trainrp), transfer functions (tansig and logsig) and the number of neurons in the hidden layer (between 9 and 33). R2 and root mean square error (RMSE) methods were used to evaluate the efficiency of artificial neural network models. The training function was found to be highly accurate (R2: 0.99999 and root mean square error: 0.314727E‐05) when the training function was “trainlm” and the number of neurons in the hidden layer was 33. The training and testing results of the artificial neural network model show that artificial neural networks can be used to estimate the specific energy absorption/energy/peak crush force value of crushboxes.

AbstractDie Kombination von Effizienz und Dauerhaftigkeit ist im Hinblick auf die Gestaltung nachhaltiger Konstruktionen von besonderer Bedeutung, entsprechend sind Kenntnisse zur Verzinkung hochfester Stähle von zunehmendem Interesse. Im Rahmen einer vertiefenden Studie wurde am Baustahl S620QH der Einfluss der Verzinkung unter Variation der Verzinkungstemperatur und ‐dauer auf die mechanischen Eigenschaften untersucht. Hierzu wurden sowohl Zug‐ und Kerbschlagbiegeversuche als auch begleitende Materialsimulationen durchgeführt. Im Ergebnis zeigt sich, dass bei der klassischen Verzinkung im Bereich üblicher Prozessparameter, nämlich einer Verzinkungstemperatur im Bereich von 440 °C bis 460 °C sowie Tauchdauern bis 20 Minuten, keine nennenswerten Effekte auf die Eigenschaften des Stahls auftreten. Bei der Hochtemperaturverzinkung wirkt sich die Temperatur in Höhe von 550 °C bei langen Tauchdauern nicht auf die Festigkeit und Duktilität, jedoch zähigkeitsmindernd auf die Stahlsorte S620QH aus. Die parallelen simulativen Untersuchungen weisen darauf hin, dass durch eine erneute Erwärmung die Ausscheidungshärtung mit steigender Temperatur, temperaturabhängig beschleunigt und weitere feine Ausscheidungen ermöglicht werden und dies für den Effekt ursächlich ist. Daraus wird die Empfehlung zur Einhaltung einer Anlasstemperatur von mindestens 580 °C für die letzte Wärmebehandlung des Vergütungsprozesses von warmgefertigten Hohlprofilen nach DIN EN 10210‐3 abgeleitet.

AbstractBackgroundATX‐FGF/SCA27A has been exclusively associated with heterozygous variants in the FGF14 gene, presenting with postural tremor, slowly progressive cerebellar ataxia, and psychiatric and behavioral disturbances.ObjectivesThis study describes the first case of ATX‐FGF/SCA27A linked to a biallelic frameshift variant in the FGF14 gene.MethodsWhole‐exome sequencing (WES) was conducted using the Illumina NovaSeq 6000 platform, and the identified variant was confirmed using Sanger sequencing.ResultsWe report the first case of autosomal recessive FGF14‐related cerebellar ataxia caused by a c.75del variant resulting in p.Leu26Serfs*51 truncation of the FGF14 protein. This variant was found in a patient born to consanguineous parents and presented with a complex congenital nonprogressive cerebellar disorder accompanied by neurodevelopmental delay, intellectual disability, and prominent drug‐responsive paroxysmal non‐kinesigenic dyskinesia. Segregation analysis confirmed that the homozygous variant was inherited from heterozygous parents who developed mild gait ataxia and tremor in their 40s.ConclusionsBiallelic loss‐of‐function variants in FGF14 are a rare cause of inherited cerebellar ataxia and expand the current genetic spectrum of ATX‐FGF14. © 2024 International Parkinson and Movement Disorder Society.

Published: December 2024

ABSTRACTα‐Synuclein (α‐syn), a pathological hallmark of PD, is emerging as a bridging element at the crossroads between neuro/immune‐inflammatory responses and neurodegeneration in PD. Several evidence show that pathological α‐syn accumulates in neuronal and non‐neuronal cells (i.e., neurons, microglia, macrophages, skin cells, and intestinal cells) in central and peripheral tissues since the prodromal phase of the disease, contributing to brain pathology. Indeed, pathological α‐syn deposition can promote neurogenic/immune‐inflammatory responses that contribute to systemic and central neuroinflammation associated with PD. After providing an overview of the structure and functions of physiological α‐syn as well as its pathological forms, we review current studies about the role of neuronal and non‐neuronal α‐syn at the crossroads between neuroinflammation and neurodegeneration in PD. In addition, we provide an overview of the correlation between the accumulation of α‐syn in central and peripheral tissues and PD, related symptoms, and neuroinflammation. Special attention was paid to discussing whether targeting α‐syn can represent a suitable therapeutical approach for PD.

AbstractBackgroundThe complementary absorption contrast CT (ACT) and differential phase contrast CT (DPCT) can be generated simultaneously from an x‐ray computed tomography (CT) imaging system incorporated with grating interferometer. However, it has been reported that ACT images exhibit better spatial resolution than DPCT images. By far, the primary cause of such discrepancy remains unclear.PurposeThe purpose of this study is to investigate the underlying cause of the resolution discrepancy between ACT and DPCT in a grating interferometer CT imaging system.MethodsIn this study, theoretical derivations were performed with a ‐phase Talbot–Lau grating interferometer system to model the signal formation mechanism of absorption imaging and phase imaging, respectively. In addition, physical, and numerical experiments were conducted to verify the theoretical findings and assess the resolution discrepancy between ACT and DPCT under various conditions. Herein, the ACT and DPCT images were reconstructed from the filtered‐back‐projection algorithm using a standard Ramp filter and a standard Hilbert filter, respectively.ResultsExperiments demonstrated that the spatial resolution of ACT and DPCT images are primarily impacted by the beam diffraction induced signal splitting. In particular, lower modulation transfer function (MTF) was observed for DPCT than ACT due to the opposite‐superposition of phase signals. In addition, factors such as focal spot size, beam spectra, object composition, sample size, and detector pixel size were found to have minor impacts on the MTFs of both ACT and DPCT.ConclusionsIn conclusion, this study reveals that the opposite‐superposition of split phase signals causes the spatial resolution reduction in DPCT imaging.
Dynamic performances of a double‐layer vibration isolation system: Nonlinear modeling and experimental validation
Authors: Zheng Chao , Gao Jin , Liu Jianchao , Xue Xin 
Published: December 2024

AbstractThis work aims to identify ways to achieve dynamic performances of a novel double‐layer vibration isolation system (DL‐VIS) capable of achieving multi‐directional isolation and extreme environmental adaptability. A forward modeling approach applicable to complex systems has been developed and analyses of nonlinear dynamic characteristics under different working conditions are performed. First, by integrating with constitutive models in terms of individual elastic elements and the connective relationships within the structure, multidirectional constitutive models for isolation devices are established. Further, the decomposition of linear and nonlinear stiffness components in different directions is performed using the Taylor expansion method. Subsequently, the dynamic response under sinusoidal sweep frequency loading is obtained using the related stiffnesses in the dynamic model and adopting the extended harmonic balance method. The effects of stiffness, damping, and a nonlinear stiffness gradient on the DL‐VIS response are thoroughly evaluated. Finally, the vibration isolation performance and nonlinear dynamics under different working conditions are examined, and the proposed dynamic model is experimentally validated. The results indicate that the response of DL‐VIS varies significantly under different working conditions, particularly under overload conditions. The nonlinear characteristics lead to wide‐band instability near the natural frequency and excellent vibration attenuation performance in multiple directions. The theoretical model agrees well with the experimental results in the nonresonant region and near the first resonant peak, which proves the prediction accuracy in the low‐frequency range. These findings provide robust theoretical and technical support for the design and performance optimization of isolation systems.

ABSTRACTObjectivesFailures and complications associated with treatments comprising laparoscopic sacrohysteropexy (SHP) for advanced pelvic organ prolapse (POP) are unclear. We compared failure rates associated with SHP and laparoscopic supracervical hysterectomy (SCH)/sacrocolpopexy (SCP) for advanced POP to determine whether they differed.MethodsClinical data of patients who underwent SHP (n = 52) and SCH/SCP (n = 209) were retrospectively examined. Only patients with advanced Pelvic Organ Prolapse Quantification stage III or IV were included. A single surgeon performed the procedures between October 2019 and October 2022. The primary objective was to compare the composite failure (CF) rates of both groups during the first year after surgery. CF was defined as the leading edge of any compartment beyond the hymen, the presence of subjective bulging, or the need for reoperation. The secondary objective was to analyze complications within 30 days and 1 year postoperatively.ResultsCF rates at 1 year were 13.5% and 5.7% with SHP and SCH/SCP, respectively (odds ratio [OR], 2.54; 95% confidence interval [CI], 0.80–7.48; p = 0.072). The 30‐day perioperative complication rates were 3.8% and 3.3% with SHP and SCH/SCP, respectively (OR, 0.66; 95% CI, 0.069–3.1). The postoperative complication rates were 1.9% and 4.3% with SHP and SCH/SCP, respectively (OR, 0.44; 95% CI, 0.0097–3.3).ConclusionsComplications associated with SHP for advanced POP did not differ from those associated with SCH/SCP. However, the occurrence of CF was higher with SHP, indicating a potentially clinically meaningful difference.Clinical Trial RegistrationThis retrospective cohort study of human participants performed at Hokusuikai‐Kinen Hospital was conducted in accordance with the principles embodied in the Declaration of Helsinki and approved by the Institutional Review Board (approval number 2022‐080).
Angle‐Free Cluster‐Robust Ritz Value Bounds for Restarted Block Eigensolvers
Authors: Zhou Ming , Knyazev Andrew , Neymeyr Klaus 
Published: December 2024

ABSTRACTConvergence rates of block iterations for solving Hermitian eigenvalue problems typically measure the errors of Ritz values approximating eigenvalues. These errors are usually bounded in terms of principal angles between the initial or iterative subspace and the invariant subspace associated with the target eigenvalues. Such bounds cannot be applied repeatedly as necessary for investigating multiple steps of restarted block eigensolvers since the left and right‐hand sides of the bounds use respectively angle‐free and angle‐dependent terms. They must be combined with additional bounds, which could cause an overestimation. Alternative bounds that are completely angle‐free and depend only on the errors of Ritz values have been introduced decades ago but only for a single extreme Ritz value. We revisit and extend these bounds to all Ritz values via repeatable intermediate bounds that enable a priori cluster‐robust bounds for restarted block Krylov subspace eigensolvers.

Published: December 2024

ABSTRACTAimsTo explore clinical facilitators' understanding, experiences and perceptions of their role in supporting registered nurse students (RNS) who experience workplace violence (WPV) during clinical placement.DesignAn exploratory, qualitative design.Methods and Data SourceData were collected between September and November 2022 using semi‐structured interviews of 1‐h duration with 11 clinical facilitators working in South Australia. The interviews were transcribed verbatim and analysed using thematic analysis.ResultsParticipants reported that WPV is experienced in many forms, including verbal and physical violence towards RNS during clinical placements. Clinical facilitators are not always aware of this experience and have mixed abilities to resolve the damage. Most importantly, clinical facilitators saw themselves as disempowered to provide the support required by RNS after WPV incidents as they perceived themselves as visitors to the facilities.ConclusionFindings indicate that a clinical facilitator's scope and ability to support a RNS is often not at a level where real impact and safety can occur. Varying perceptions of what WPV is, what is acceptable, and the authority or influence of a clinical facilitator have all informed this issue and need to be considered in developing strategies to address WPV towards RNS.Implications for the Nursing ProfessionThis study highlights that by understanding the causation of WPV and recognising the lack of influence and scope of clinical facilitators to act to support RNS during WPV events, positive industry changes can be instigated to promote student placement experiences and healthcare provision.ImpactClinical facilitators felt limited in their role to support RNS experiencing WPV. This research impacts future nursing students, education providers, clinical facilitators and clinical placement providers.Reporting MethodCOREQ guidelines were utilised to report qualitative research.No Patient or Public ContributionThis paper explores specifically the clinical facilitators' perceptions of WPV.
Enhancing Power Quality in Smart Grid‐Connected Renewable Energy Systems Using A Hybrid Deep Learning‐Based DSTATCOM: Self‐Improved Jellyfish Optimizer (Si‐Jo)
Authors: Nishanth K. , Saru Krishna S. 
Published: December 2024

ABSTRACTThis manuscript introduces a robust stochastic optimization technique for real‐time energy management in household solar (PV) storage systems, which addresses the constraints provided by the stochastic nature of solar power and load demand. Traditional offline solutions for day‐ahead Battery Energy Storage (BES) scheduling frequently result in real‐time energy losses, while online alternatives do not adequately reduce electricity prices. The proposed system combines an offline optimization model with a real‐time rule‐based controller and a deep learning‐based Conditional Self‐Attention Generative Adversarial Network (CSAGAN) for load and solar generation predictions to address these constraints. The War Strategy Optimization (WSO) Algorithm, which operates inside a receding horizon framework, optimizes BES dispatch set‐points to lower daily electricity costs. The research also introduces a DSTATCOM‐based hybrid technique for improving power quality (PQ) in grid‐connected solar and wind systems, which makes use of a hybrid deep learning model consisting of Deep Belief Networks (DBNs) and Multilayer Perceptrons (MLPs). The Self‐Increased Jellyfish Optimizer (SI‐JO) generates control signals and optimizes the six‐leg voltage source converter (VSC) and the buck‐boost converter. MATLAB simulations show considerable increases in energy efficiency, harmonic distortion reduction, and system stability under various irradiance and grid fault scenarios, demonstrating the efficacy of the proposed techniques.

AbstractResearch on how plants respond to hypoxia has concentrated on model organisms where tissues can only survive hypoxic conditions for a few hours to a few days. In contrast, hypoxic conditions are used commercially as a method to prolong the shelf life of Malus domestica (apple) fruit for up to a year of storage without substantial changes in fruit quality, not to mention a lack of tissue death. This ability of apples to withstand protracted hypoxic conditions is an interesting adaptation that has had limited molecular investigation despite its economic importance. Here, we investigate the long‐term apple hypoxia response using a time‐course RNA‐seq analysis of several postharvest storage conditions. We use phylogenetics, differential expression, and regulatory networks to identify genes that regulate and are regulated by the hypoxia response. We identify potential neofunctionalization of core‐hypoxia response genes in apples, including novel regulation of group VII ethylene response factor (ERF VII) and plant cysteine oxidase (PCO) family members.
Hawking Radiation of Renormalization Group Improved Regular Black Holes
Authors: Konoplya Roman A. 
Published: December 2024

AbstractA renormalization group approach based on the idea that the primary contribution to the Schwarzschild‐like black hole spacetime arises from the value of the gravitational coupling is considered. The latter depends on the distance from the origin and approaches its classical value in the far zone. However, at some stage, this approach introduces an arbitrariness in choosing an identification parameter. There are three approaches to the identification: the modified proper length (the Bonanno–Reuter metric), the Kretschmann scalar (the Hayward metric), and an iterative, and, in a sense, coordinate‐independent procedure (Dymnikova solution). Using the Wentzel–Kramers–Brillouin method, gray‐body factors are calculated for the Standard Model massless test fields and their corresponding energy emission rates. For all of these solutions, it is found that the intensity of Hawking radiation of massless fields is significantly suppressed by several or more orders once the quantum correction is taken into consideration. This indicates that the effect of suppression of the Hawking radiation may be appropriate to the quantum corrected black holes in asymptotically safe gravity in general and is independent on the particular choice of the identification parameter.
A Background History of the Sustainable Development Goals
Authors: Jacob Jerin 
Published: December 2024

ABSTRACTWhile the UN's Sustainable Development Goals (SDGs) have become a prominent guideline in the developmental course of the planet, it is important to study the history of these goals to gain an in‐depth understanding of the concept of sustainability underlying them. Although some studies have been conducted on the history of the SDGs, this paper aims to provide a different and creative overview of their evolution. Moreover, the current research depicts the growth in the notion of development and sustainability over the past few decades. The conclusions hint at the possible future evolution of the history towards a post‐growth era. The findings were reached by conducting a literature review of related scholarly works and the UN's published documents. The study divides the narrated history of Sustainable Development thinking into six stages: sprouting, seedling, vegetative, budding, flowering and ripening. Thus, this paper describes how the concept of development got evolved from ‘development with assistance’ to a sustainable development that comprises four pillars: environment, society, economy and governance, and how it tends to evolve further.
Overview of Psocodea in Eocene Oise amber and implications for the transition to modern‐day barklice communities
Authors: Álvarez‐Parra Sergio , Nel André , Azar Dany 
Published: December 2024

AbstractPsocodea is an insect order including barklice, booklice and parasitic lice. The oldest evidence of diversification in the crown group dates back to the Cretaceous, represented by a high diversity and abundance in several amber deposits. However, the Cenozoic record of psocodeans is less known. Here, we present a review of the Psocodea from the lower Eocene amber of Oise in France, including a study of 83 new specimens. The record of psocids in Oise amber is currently represented by 144 specimens corresponding to 14 species in 14 genera in 10 families of the three suborders: Trogiomorpha, Troctomorpha and Psocomorpha. The only known ‘archaeatropid’ Empheriidae from the Eocene, Danyazarius magnificus gen. et sp. nov., is described. In addition, the genera Annulipsyllipsocus and Sinopsyllipsocus are formally synonymized under Psyllipsocus. Wing venations of all psocid species from Oise amber are illustrated, enabling easier comparison with other taxa. A key for determination of all known psocodean species from Oise amber is given. We notice a rarity of nymphs in relation to the total number of specimens, and provide an account of known sexes, the female being more numerous than the male. We also compare the diversity with that of Baltic amber. Interestingly, Psocomorpha is the least diverse suborder in Oise amber, as in Cretaceous amber, although this suborder is the most numerous, as in current ecosystems. This study opens a window onto the evolutionary history of Psocodea during the Cenozoic and the transition to the modern‐day barklice communities.
