Published: October 2022

AbstractWe investigate probabilistic seismic hazard analysis (PSHA) in low-seismicity regions in which epistemic uncertainties are largely due to the sparsity of data, with a focus on Finland, northern Europe. We investigate the sensitivity of site-specific PSHA outcomes to different choices of basic input parameters, starting from preexisting PSHA models of the nuclear licensees in the country, without producing a final hazard curve. The outcome shows that the parameters and models needed to estimate future seismicity rates from actual observations, in particular the b value, seismicity rates, and the largest possible magnitude, Mmax, as well as the median ground-motion prediction equation, play significant roles. The sensitivity also depends on the spectral frequency; for example, the effect of Mmax is significant especially for a low-frequency hazard at annual frequency of exceedance 10−5 but more moderate for peak ground acceleration. The delineation of seismic source zones (SSZs) remains ambiguous in regions of low seismicity. This, combined with the dominance of the host SSZ and its seismicity parameters, may have a substantial impact on the outcome. Our results are quantitatively applicable to Finland, but may also be of relevance to other low-seismicity regions in Europe and elsewhere. For future work we recommend the exploration of PSHA sensitivity with focus on the host SSZ with its immediate vicinity and the b value around the site of interest.
Feller generators with measurable lower order terms
Authors: Kühn Franziska , Kunze Markus 
Published: October 2022

AbstractWe study perturbations of Feller generators by ‘lower order terms’ with measurable coefficients. We investigate which properties of the original semigroup—such as positivity, conservativeness and the Feller property—are passed on to the perturbed semigroup. We give several examples and discuss applications in the theory of martingale problems and stochastic differential equations with measurable coefficients.

Published: October 2022

Abstract
Purpose
Normative utility scores represent the health related quality of life of the general population, are of utmost importance in cost-effectiveness studies and should reflect relevant sexes and age groups. The aim of this study was to estimate EQ-5D-5L normative utility scores in a population of Dutch females, stratified by age, and to compare these scores to those of female populations of three other countries.

Methods
Dutch women completed the EQ-5D-5L online between January and July 2020. Mean normative utilities were computed using the Dutch EQ-5D-5L value set, stratified by age, tested for differences using the Kruskall–Wallis test, and compared to normative utility scores of female populations elsewhere. Additionally, to support the use of the Dutch EQ-5D-5L data in other settings, normative utility scores were also calculated by applying the value sets of Germany, United Kingdom and USA.

Results
Data of 9037 women were analyzed and the weighted mean utility score was 0.911 (SD 0.155, 95% CI 0.908–0.914). The mean normative utility scores differed between age groups, showing lower scores in older females. Compared to other normative utility scores of female populations, Dutch mean utilities were consistently higher except for age groups 18–24 and 25–34. With the three country-specific value sets, new age-specific mean normative utility scores were provided.

Conclusion
This study provides mean normative utility scores of a large cohort of Dutch females per age group, which were found to be lower in older age groups. Utility scores calculated with three other value sets were made available.

Published: October 2022

AbstractDissection of regulatory network that control wood structure is highly challenging in functional genomics. Nevertheless, due to the availability of genomic, transcriptomic and proteomic sequences, a large amount of information is available for use in achieving this goal. MicroRNAs, which compose a class of small non-coding RNA molecules that inhibit protein translation by targeting mRNA cleavage sites and thus regulate a wide variety of developmental and physiological processes in plants, are important parts of this regulatory network. These findings and the availability of sequence information have made it possible to carry out an in silico analysis to predict and annotate miRNAs and their target genes associated with an important factor affecting wood rigidity, microfibril angle (MFA), throughout the Populus trichocarpa Hook. genome. Our computational approach revealed miRNAs and their targets via ESTs, sequences putatively associated with microfibril angle. In total, 250 miRNAs were identified as RNA molecules with roles in the silencing and post-transcriptional regulation of the expression of nine genes. We found SHY2, IAA4 (ATAUX2–11), BZIP60, AP2, MYB15, ABI3, MYB17, LAF1 and MYB28 as important nodes in a network with possible role in MFA determination. Other co-expressed genes putatively involved in this regulatory system were also identified by construction of a co-expression network. The candidate genes from this study may help unravel the regulatory networks putatively linked to microfibril angle.

Authors: Sato Ryosuke , Vatic Mirela , da Fonseca Guilherme Wesley Peixoto , von Haehling Stephan 
Published: October 2022

Abstract
Purpose of Review
Sarcopenia and frailty are common in patients with heart failure (HF) and are strongly associated with prognosis. This review aims to examine promising biomarkers that can guide physicians in identifying sarcopenia and frailty in HF.

Recent Findings
Traditional biomarkers including C-reactive protein, aminotransaminase, myostatin, and urinary creatinine as well as novel biomarkers including microRNAs, suppression of tumorigenicity 2 (ST2), galectin-3, and procollagen type III N-terminal peptide may help in predicting the development of sarcopenia and frailty in HF patients. Among those biomarkers, aminotransferase, urinary creatinine, and ST2 predicted the prognosis in HF patients with sarcopenia and frailty.

Summary
This review outlines the current knowledge of biomarkers that are considered promising for diagnosing sarcopenia and frailty in HF. The listed biomarkers might support the diagnosis, prognosis, and therapeutic decisions for sarcopenia and frailty in HF patients.
Optimized multi-layer radial permanent magnet bearing with an eddy current damping systems
Authors: Bekinal Siddappa Iranna , Deshwal Dhruv , Srinivas Vijay Gaddale 
Published: October 2022

AbstractThis research work proposes the conventional and novel eddy current damping systems (CECDS & NECDS) for an optimized multi-layer radial permanent magnet bearing, which is axially magnetized. Firstly, the design and optimization of a bearing are carried out by adopting the general procedure for maximum radial force and stiffness by selecting stator outer diameter, radial air gap, and length as parameters. The maximum radial force and stiffness concerning an optimized structure are also calculated using semi-analytical equations, and force results are validated with three-dimensional (3D) finite element analysis results. Then, the analysis of both damping systems is carried out for damping forces and coefficients using 3D electromagnetic transient analysis in ANSYS. The proposed dampers provide adequate damping to the bearing structure, and conductor plate thickness significantly affects the damping characteristics. The NECDS could be used to replace the conventional type as it eliminates the effect of reduced radial air gap on the performance of the bearing.
Regressive Erosion at River Coca in Northeast Ecuador: Landslide Monitoring with Sentinel-1 to Support Disaster Risk Management

Published: October 2022

AbstractAfter the collapse of the San Rafael waterfall in Northeast Ecuador on 2 February 2020, a regressive erosion started along the River Coca putting national infrastructure, the environment and indigenous communities at risk. A fast monitoring of areas exposed to landslides on local scales therefore is necessary to provide adequate risk management for the region. The study area, located in the Andean tropics close to the volcano Reventador, is characterized by steep slopes, seismic activity and high rainfall throughout the year. Sentinel-1 SAR data provide a solution for time-series monitoring in the region as imagery is available day and night and not affected by cloud cover. Landslide monitoring with Sentinel-1 SAR data was implemented using a bi-temporal change detection (BCD) with SNAP and a sequential change detection (SCD) with EESA Docker and the Google Earth Engine (GEE) aiming at the identification of a suited approach for fast disaster monitoring and management. The SCD showed an overall accuracy of 0.91 compared to 0.88 using the BCD approach validated with high-resolution imagery. Based on the landslide detection, hazard variables could be further identified to support future hazard and risk assessment. Fast processing of Sentinel-1 time-series data in a cloud-based environment allows for near real-time monitoring of ongoing erosion and provides a potential for pro-active measures to protect the national economy, the environment and the society.
Lightweight design approach of an LFT-metal multi-material vehicle door concept
Authors: Li Danshi , Fang Xiangfan 
Published: October 2022

AbstractThis work presents a new approach to design and validate an economical lightweight multi-material roof-integrated vehicle door concept made of long-fiber thermoplastics (LFT) and metals with the consideration of package constrain, critical static and crash loading cases. A novel “two-ring” door structure is introduced, which consists of a major load-bearing region and a minor load-bearing but highly function-integrated region. This concept design concentrates on using cost-efficient lightweight materials, such as aluminum, LFTs and uni-directional tapes (UD-Tapes), as well as corresponding mass-production methods. Using the topology and parameter optimization along with the load anisotropy analysis, the rib structure on the door concept is optimized and the effective usage of UD-Tapes is guaranteed. In comparison to the steel reference, the final LFT-metal multi-material door concept achieves 20% weight reduction with a comparable or improved mechanical performance.
A questionnaire measure of adult attachment anxiety correlates with frontal hemispheric asymmetry in sleep spindle activity
Authors: Becske Melinda , Lázár Imre , Bódizs Róbert 
Published: October 2022

AbstractSubjects with high levels of attachment anxiety and neuroticism were proposed to be characterized by higher relative right rather than left frontal activity. Since sleep spindles are argued to reflect enhanced offline neuroplasticity, higher spindle activity measured over the right frontal areas relative to the corresponding left frontal ones could index higher attachment anxiety and neuroticism. Our aim was to explore the relationship between the lateralization patterns of frontally dominant slow sleep spindles and questionnaire measures of adult attachment anxiety and neuroticism. Thirty-four healthy subjects (male = 19;Mage = 31.64; SDage = 9.5) were enrolled in our preliminary study. Second night EEG/polysomnography records and questionnaire measures of personality (Zuckerman–Kuhlman Personality Questionnaire) and adult attachment (Relationship Scales Questionnaire) were collected. Frontal slow sleep spindles were measured by the Individual Adjustment Method (IAM), whereas hemispheric asymmetry indexes of spindle occurrence rate, duration, and amplitude were derived as normalized left–right differences (electrode pairs: Fp1–Fp2, F3–F4, and F7–F8). Relative right lateralization of frontolateral and frontopolar slow sleep spindle density and mid-frontal slow spindle duration were associated with attachment anxiety, but spindle lateralization was less closely related to neuroticism. The relationships between frontal slow spindle laterality and attachment anxiety remained statistically significant even after controlling for the effect of neuroticism, whereas attachment avoidance–independence was not correlated with frontal slow spindle lateralization. Right frontal lateralization of slow sleep spindle activity might indicate attachment status in terms of the negative view of the self.
On the Role of Material Balances in the Synthesis of Overall Process Control Systems
Authors: Bolton Leslie , Smith Robin 
Published: October 2022

Abstract
The synthesis of control systems for overall processes remains a challenge. Whilst a number of automated approaches have been explored academically, in practice systems are mainly synthesised using experience and intuition in conjunction with dynamic simulation software. An approach is presented in this paper for the systematic synthesis of overall process control systems which is simple, practical and appropriate for use at the undergraduate teaching level. Many potential problems can be identified and avoided in the synthesis of process control systems by ensuring that the control system can maintain a steady-state control of the overall mass, the mass of the individual components and, where necessary, multiple phases. Processes with recycles are vulnerable to process control problems when the overall mass balance of the system containing the recycle is not correctly managed. This can be overcome by self-regulation (perhaps involving process design changes) or by changing the structure of the control system. Achieving and maintaining the material balance are the main purposes of the majority of controllers in most chemical processes. Without robust delivery of material balance control, higher level control objectives (such as quality controls) are unlikely to be met reliably. This paper presents a step-wise approach to the synthesis of overall process control systems that avoids many potential problems by identifying which process parameters can be manipulated to achieve the intended process mass balance and designing the control structure accordingly.

Published: October 2022

AbstractThe purpose of this paper is to explore the status of entrepreneurship education programs (EEPs) in Indonesia, expanding similar papers on related Australian EEPs in 2019 and Malaysian EEPs in 2021. The aim is to review neoteric global best practice entrepreneurship education (EE), aligning context and specific inference of EEPs in Indonesian Higher Education Institutions (HEIs) within dynamic entrepreneurial ecosystems. We provide a descriptive and emergent inquiry approach consisting of a review of prominent scholarship within the context of EEPs in Indonesia, together with a first of its kind quantitative component depicting the distribution of entrepreneurship spirit, EEPs, accelerators and entrepreneurship support services within HEIs. The paper highlights the sparse and inconsistent distribution across EEPs in Indonesia, further characterized by only a few dominant HEIs specializing in EE. The findings provide critical insights for HEI leaders, researchers, practitioners, and administrators wishing to enhance entrepreneurship and start-up resources at Indonesian HEIs. Further research, however, is recommended especially with respect to the efficacy and impact of these EEPs.

Published: October 2022

Abstract
This work intends to provide seismic vulnerability analysis for a building stock in Al Khalifa District, Fatimid Cairo while focusing on the historic buildings in the area. The work represents part of an interdisciplinary study targeting the management and conservation of a UNESCO World Heritage Site. The project inspects several aspects including behavior of masonry walls, structural health monitoring of selected structures, conservation studies, in addition to influence of rising ground water. In the current study, seismicity of Egypt generally and Cairo specifically is reviewed. Afterwards, large-scale seismic vulnerability is adopted to calculate the vulnerability index for buildings within the study area. Data are collected through extensive on-site surveys for more than one hundred buildings. Observed typologies are listed alongside possible mechanisms of failure. Egypt has moderate seismic hazard; however, many buildings are prone to damage due to inadequate seismic design. This leads to retrofitting requirements to reduce seismic vulnerability and adhere to imposed seismic requirements in design codes. The study is intended to understand seismic risk of buildings within study area as part of a comprehensive study. Developed vulnerability map show that many buildings are prone to damage during seismic events.

Article Highlights

Seismic vulnerability of building samples in a study area within Old Cairo is assessed and presented in the form of a vulnerability map.

Structural characteristics of buildings are detailed and investigated.

Signs of deterioration are analyzed, and mechanisms of failure are featured.
Evolution of a cognitive architecture on the basis of a functional core
Authors: Serov Alexander 
Published: October 2022

AbstractIndustry 4.0 assumes the use of intelligent components integrated into a single system and capable of interacting with each other without human intervention. Autonomous cognitive agents are the technological basis for building such systems. One of the main problems of modern cognitive architectures is an excessively schematic approach to modeling the processes of cognitive activity. It does not allow the creation of a universal architecture that would be capable of reproducing higher nervous functions without using a predetermined set of perception patterns. This paper proposes an evolutionary approach to creating a cognitive architecture. The basis of this approach is the use of some functional core, which consistently generates the intellectual functions of an autonomous agent. We are considering a cognitive architecture that includes components, the interaction of which ensures the evolution of the agent. The discussion of the development of intelligence is carried out using the conceptual apparatus of semiotics. This allows us to consider the task of developing cognitive functions as a problem of establishing a connection between the Merkwelt and the Werkwelt through the creation of the Innenwelt. The problem of early postnatal ontogenesis is investigated on the basis of the theory of constructivism: we discuss the requirements for the functional core and its composition, as well as the mechanism that initiates the process of cognition. We have developed a numerical method for modeling cognitive activities present at an early stage of ontogenesis. The method was used for the creation of the Cognitive Sensory System.
Approaches to tailor the cooling supply to the grinding process

Published: October 2022

Abstract
This study presents original research of the investigation of the coolant supply to the contact area with two different approaches. The cooling and lubrication are key aspects of manufacturing processes such as grinding to achieve a high surface quality at high productivity. The coolant supply to the contact area has a high impact on the performance of the coolant. This paper presents the results from two approaches to tailoring the coolant supply for conventional and high-performance processes. An analytical approach is established to determine the coolant outlet velocity. Afterward, a sensor is developed to measure the coolant velocity at the nozzle. Conclusively, the influence of the coolant velocity on the volume flow through the contact zone is investigated. The results of this study highlight the importance of coolant outlet velocities of at least 60% of the cutting speed. The two approaches outline low impact possibilities to ensure optimal coolant outlet velocities and thus low thermal loads during the grinding process.
