Rehabilitation robot following motion control algorithm based on human behavior intention
Authors: Miao Ming da , Gao Xue shan , Zhao Jun , Zhao Peng 
Published: July 2022

AbstractIn response to the current problem of low intelligence of mobile lower limb motor rehabilitation aids. This paper proposes an intelligent control scheme based on human movement behavior in order to control the rehabilitation robot to follow the patient’s movement. Firstly, a multi-sensor data acquisition system is designed according to the rehabilitation needs of the patient and the movement characteristics of the human body. A mathematical model of movement behavior is then established. By analyzing and processing motion data, the change in the center of gravity of the human body and the behavior intention signal are derived and used as a control command for the robot to follow the human body’s movement. Secondly, in order to improve the control effect of rehabilitation robot following human motion, an adaptive radial basis function neural network sliding mode controller (ARBFNNSMC) is designed based on the robot dynamic model. The adaptive adjustment of switching gain coefficient is performed by radial basis function neural network. The controller can overcome the influence caused by the change of robot control system parameters due to the fluctuation of the center of gravity of human body, enhance the adaptability of the system to other disturbance factors, and improve the accuracy of following human body motion. Finally, the motion following experiment of the rehabilitation robot is performed. The experimental results show that the robot can recognize the motion intention of human body and perform the training goal of following different subjects to complete straight lines and curves. The correctness of human motion behavior model and robot control algorithm is verified, which shows the feasibility of the intelligent control method proposed in this paper.
CsmithEdge: more effective compiler testing by handling undefined behaviour less conservatively
Authors: Even-Mendoza Karine , Cadar Cristian , Donaldson Alastair F. 
Published: July 2022

AbstractCompiler fuzzing techniques require a means of generating programs that are free from undefined behaviour (UB) to reliably reveal miscompilation bugs. Existing program generators such as Csmith achieve UB-freedom by heavily restricting the form of generated programs. The idiomatic nature of the resulting programs risks limiting the test coverage they can offer, and thus the compiler bugs they can discover. We investigate the idea of adapting existing fuzzers to be less restrictive concerning UB, in the practical setting of C compiler testing via a new tool, CsmithEdge, which extends Csmith. CsmithEdge probabilistically weakens the constraints used to enforce UB-freedom, thus generated programs are no longer guaranteed to be UB-free. It then employs several off-the-shelf UB detection tools and a novel dynamic analysis to (a) detect cases where the generated program exhibits UB and (b) determine where Csmith has been too conservative in its use of safe math wrappers that guarantee UB-freedom for arithmetic operations, removing the use of redundant ones. The resulting UB-free programs can be used to test for miscompilation bugs via differential testing. The non-UB-free programs can still be used to check that the compiler under test does not crash or hang. Our experiments on recent versions of GCC, LLVM and the Microsoft Visual Studio Compiler show that CsmithEdge was able to discover 7 previously unknown miscompilation bugs (5 already fixed in response to our reports) that could not be found via intensive testing using Csmith, and 2 compiler-hang bugs that were fixed independently shortly before we considered reporting them.

Published: July 2022

AbstractGraphene oxide (GO) nanostructures are systems with many fascinating novel properties that can be used to study new science and have significant promise for applications. In this study, graphene oxide was prepared using the modified Hummer’s method. In addition, potassium ferrite is a good candidate for biomedical application, as iron and potassium are biocompatible and non-toxic materials. Mg0.85K0.3Fe2O4/GO nanocomposites were prepared by the citrate auto-combustion method. The effect of adding GO to Mg0.85K0.3Fe2O4 on structure, morphology, electrical, and magnetic properties was discussed. Samples under investigation were characterized using XRD, infrared spectroscopy (IR), high-resolution transmission electron microscopy (HRTEM), and atomic force microscopy (AFM). The crystallite size of prepared samples was decreased from 28.098 to18.148 nm by increasing GO content. Scanning electron microscope (SEM) confirms the successful adhesion of Mg0.85K0.3Fe2O4 nanoparticles on graphene oxide sheets, which are dispersed in a metal oxide matrix. EDAX analysis confirms the existence of C, O, K, Mg, and Fe elements present in the samples. Magnetic properties were studied by VSM and Faraday's method. GO has a significant effect on the magnetic properties of nanocomposites. For instance, the saturation magnetization and Curie temperature have diverse values, which will be appropriate for numerous applications.
Symmetry-Resolved Entanglement Entropy in Critical Free-Fermion Chains
Authors: Jones Nick G. 
Published: July 2022

AbstractThe symmetry-resolved Rényi entanglement entropy is the Rényi entanglement entropy of each symmetry sector of a density matrix$$\rho $$ρ. This experimentally relevant quantity is known to have rich theoretical connections to conformal field theory (CFT). For a family of critical free-fermion chains, we present a rigorous lattice-based derivation of its scaling properties using the theory of Toeplitz determinants. We consider a class of critical quantum chains with a microscopic U(1) symmetry; each chain has a low energy description given byNmassless Dirac fermions. For the density matrix,$$\rho _A$$ρA, of subsystems ofLneighbouring sites we calculate the leading terms in the largeLasymptotic expansion of the symmetry-resolved Rényi entanglement entropies. This follows from a largeLexpansion of the charged moments of$$\rho _A$$ρA; we derive$$\mathrm {tr}(\mathrm {e}^{\mathrm {i}\alpha Q_A} \rho _A^n)~=~a \mathrm {e}^{\mathrm {i}\alpha \langle Q_A\rangle } (\sigma L)^{-x}(1+O(L^{-\mu }))$$tr(eiαQAρAn)=aeiα⟨QA⟩(σL)-x(1+O(L-μ)), wherea, xand$$\mu $$μare universal and$$\sigma $$σdepends only on theNFermi momenta. We show that the exponentxcorresponds to the expectation from CFT analysis. The error term$$O(L^{-\mu })$$O(L-μ)is consistent with but weaker than the field theory prediction$$O(L^{-2\mu })$$O(L-2μ). However, using further results and conjectures for the relevant Toeplitz determinant, we find excellent agreement with the expansion over CFT operators.
Why Some Adolescents Are Open To Their Parents’ Political Communication
Authors: Stattin Håkan , Eckstein Katharina , Amnå Erik 
Published: July 2022

AbstractThis study examines the conditions that make adolescents open to their parents’ attempts at political socialization. Based on a reformulation of the perceptual accuracy argument, that parents’ messages are filtered through correct perceptions of these messages by adolescents, the study suggests that adolescents who accurately recognize their parents’ high political sophistication are particularly likely to attend to and be open to their parents’ political communication. This proposition was tested using cluster analysis of a sample of 505 Swedish upper-secondary students and their parents (51% girls; Mage = 16.56, SD = 0.67). The analysis yielded two clusters where adolescents correctly identified (26%) and failed to correctly identify (22%) their parents’ high political sophistication, and three clusters where both parents and adolescents reported low or medium parental political sophistication (10%, 11%, and 32%). In confirmation of the hypothesis, members of the cluster group of adolescents who correctly recognized their parents’ high political sophistication were particularly aware of parents’ political socialization attempts and receptive to parents’ political communication. Moreover, these youth considered their parents’ political views as important and, accordingly, seemed to perceive their parents as political role models.
Optimization of a SWAT model by incorporating geological information through calibration strategies
Authors: Sánchez-Gómez Alejandro , Martínez-Pérez Silvia , Pérez-Chavero Francisco M. , Molina-Navarro Eugenio 
Published: July 2022

AbstractHydrological models are frequently used for water resources management. One of the most widely used is the Soil and Water Assessment Tool (SWAT). However, one weakness of SWAT is its simplicity in modeling groundwater, which might affect the representation of hydrological processes. Therefore, modeling strategies that are geared towards achieving more realistic simulations would increase the reliability and credibility of SWAT model predictions. In this study, the performance of a SWAT model in a geologically heterogeneous basin was optimized by incorporating geological properties through semi-automatic calibration strategies. Based on its geology, the basin was split into four regions, and a default calibration (Scheme I) was compared with three designed calibration schemes: a zonal calibration (Scheme II), obtaining a parameter set in each of the regions, a zonal calibration after introducing an impervious layer in an aquifuge region (Scheme III), and a final calibration scheme (Scheme IV) where an aquifer region was re-calibrated, changing a parameter controlling the required content of water in the aquifer for return flow to increase groundwater flow. The results from the four schemes were evaluated both statistically and by assessing their plausibility to determine which one resulted in the best model performance and the most realistic simulations. All schemes resulted in a satisfactory statistical model performance, but the sequential optimization in the final scheme realistically reproduced the heterogenous hydrological behavior of the geological regions within the basin. To the best of our knowledge, our work addresses this issue for the first time, providing new insights about how to simulate catchments including aquifuge substrates.
Proximity and inter-firm corruption: A transaction cost approach
Authors: Troisi Roberta , Alfano Gaetano 
Published: July 2022

AbstractThe aim of this study is to analyse inter-firm corruption and to ascertain whether the proximity of firms engaged in corruption is a significant factor. We draw on transaction cost theory to explore two forms of corrupt exchange (negotiated vs. productive) and the role of proximity in reducing transaction costs. We obtained original data from the judgements of the Italian Court of Cassation and clustered homogeneous proximities. We then used separate binomial logistic regressions to show how the relation between transaction properties, the consequences for transaction costs and forms of corrupt exchange lead to different outcomes for each subgroup of proximities. The results show that technological and geographical proximity are beneficial to both forms of exchange, leading to a reduction in exchange costs, in much the same way as legal activities. However, unlike legal exchanges, corrupt and in particular productive exchanges do not appear to benefit from social proximity.
A review of the neural control of micturition in dogs and cats: neuroanatomy, neurophysiology and neuroplasticity
Authors: Gernone Floriana , Uva Annamaria , Maiolini Arianna , Zatelli Andrea 
Published: July 2022

Abstract
This article discusses the current knowledge on the role of the neurological structures, especially the cerebellum and the hypothalamus, and compares the information with human medicine. Micturition is a complex voluntary and involuntarily mechanism. Its physiological completion strictly depends on the hierarchical organisation of the central nervous system pathways in the peripheral nervous system. Although the role of the peripheral nervous system and subcortical areas, such as brainstem centres, are well established in veterinary medicine, the role of the cerebellum and hypothalamus have been poorly investigated and understood. Lower urinary tract dysfunction is often associated with neurological diseases that cause neurogenic bladder (NB). The neuroplasticity of the nervous system in the developmental changes of the mechanism of micturition during the prenatal and postnatal periods is also analysed.
Obesity and Bariatric Surgery in Australia: Future Projection of Supply and Demand, and Costs
Authors: Dona Sithara Wanni Arachchige , Angeles Mary Rose , Nguyen Dieu , Gao Lan , Hensher Martin 
Published: July 2022

Abstract
Introduction
The prevalence of obesity is increasing in developed countries, including Australia. There is evidence that bariatric surgery is effective in losing weight and reducing risk of chronic diseases. However, access to bariatric surgery remains limited in the public health sector.

Method
We modelled population-based estimates of the likely numbers of people eligible for bariatric surgery in Australia using the recent Australian New Zealand Metabolic and Obesity Surgery Society (ANZMOSS) framework and estimated the potential costs that would be incurred from primary and subsequent reoperations in both public and private sector.

Results
The annual number of newly eligible patients is expected to rise, and hence the gap in demand is increasing relative to current baseline supply. If a 5-year program to treat all currently eligible patients was implemented, the maximum yearly demand is projected to be 341,343 primary surgeries, more than eight times the existing capacity of public and private sector, which can only offer 41,534 surgeries/year. A nine-fold increase is expected if we treat currently eligible patients over a 5-year program and all newly eligible patients as they occur each year.

Conclusion
Our results highlighted the currently highly skewed distribution of bariatric surgeries between the private and public sectors. Improving access would bring substantial benefits to many Australians, given the demonstrated cost-effectiveness and cost savings. This requires a major increase in resourcing for publicly-funded access to bariatric surgery in the first instance. A national review of priorities and resourcing for all modes of obesity treatment is required in Australia.

Artificial empathy in marketing interactions: Bridging the human-AI gap in affective and social customer experience
Authors: Liu-Thompkins Yuping , Okazaki Shintaro , Li Hairong 
Published: July 2022

AbstractArtificial intelligence (AI) continues to transform firm-customer interactions. However, current AI marketing agents are often perceived as cold and uncaring and can be poor substitutes for human-based interactions. Addressing this issue, this article argues that artificial empathy needs to become an important design consideration in the next generation of AI marketing applications. Drawing from research in diverse disciplines, we develop a systematic framework for integrating artificial empathy into AI-enabled marketing interactions. We elaborate on the key components of artificial empathy and how each component can be implemented in AI marketing agents. We further explicate and test how artificial empathy generates value for both customers and firms by bridging the AI-human gap in affective and social customer experience. Recognizing that artificial empathy may not always be desirable or relevant, we identify the requirements for artificial empathy to create value and deduce situations where it is unnecessary and, in some cases, harmful.

AbstractSocially Assistive Robots (SARs) are designed to support us in our daily life as a companion, and assistance but also to support the caregivers’ work. SARs should show personalized and human-like behavior to improve their acceptance and, consequently, their use. Additionally, they should be trustworthy by caregivers and professionals to be used as support for their work (e.g. objective assessment, decision support tools). In this context the aim of the paper is dual. Firstly, this paper aims to present and discuss the robot behavioral model based on sensing, perception, decision support, and interaction modules. The novel idea behind the proposed model is to extract and use the same multimodal features set for two purposes: (i) to profile the user, so to be used by the caregiver as a decision support tool for the assessment and monitoring of the patient; (ii) to fine-tune the human–robot interaction if they can be correlated to the social cues. Secondly, this paper aims to test in a real environment the proposed model using a SAR robot, namely ASTRO. Particularly, it measures the body posture, the gait cycle, and the handgrip strength during the walking support task. Those collected data were analyzed to assess the clinical profile and to fine-tune the physical interaction. Ten older people (65.2 ± 15.6 years) were enrolled for this study and were asked to walk with ASTRO at their normal speed for 10 m. The obtained results underline a good estimation (p < 0.05) of gait parameters, handgrip strength, and angular excursion of the torso with respect to most used instruments. Additionally, the sensory outputs were combined in the perceptual model to profile the user using non-classical and unsupervised techniques for dimensionality reduction namely T-distributed Stochastic Neighbor Embedding (t-SNE) and non-classic multidimensional scaling (nMDS). Indeed, these methods can group the participants according to their residual walking abilities.
How manufacturing firms navigate through stormy waters of digitalization: the role of dynamic capabilities, organizational factors and environmental turbulence for business model innovation
Authors: Witschel Daliborka , Baumann Dominik , Voigt Kai-Ingo 
Published: July 2022

AbstractAlthough research has shown that business model innovation (BMI) is an effective means to remain competitive in the digital age, many firms do not respond appropriately and often fail to exploit new digital opportunities. In this study, we adopt a microfoundational approach to understand the role and effects of dynamic capabilities (DCs) on BMI in the context of digitalization. Furthermore, we test how this relationship is influenced by contextual factors. Our results from a survey of German manufacturing firms demonstrate the importance of building strong DCs for effective BMI in the context of digitalization. We also highlight the advantages of an entrepreneurial leadership and mindset in this context. The study further suggests that environmental turbulence in the digital context acts as an antecedent to DCs and BMI, rather than moderating their relationship. While strategic factors indirectly affect BMI as antecedents of DCs, we found no evidence of an influence of the organizational structure.

Abstract
The transition of foods during toddlerhood and the suboptimal diets consumed in the Middle East make children susceptible to malnutrition and micronutrient deficiencies. Based on international recommendations, coupled with the merits of clinical studies on the application of young child formula (YCF), a group of fourteen experts from the Middle East reached a consensus on improving the nutritional status of toddlers. The recommendations put forth by the expert panel comprised twelve statements related to the relevance of YCF in young children; the impact of YCF on their nutritional parameters and functional outcomes; characteristics of the currently available YCF and its ideal composition; strategies to supply adequate nutrition in young children and educational needs of parents and healthcare professionals (HCPs). This consensus aims to serve as a guide to HCPs and parents, focusing on improving the nutritional balance in toddlers in the Middle Eastern region. The panellists considere YCF to be one of the potential solutions to improve the nutritional status of young children in the region. Other strategies to improve the nutritional status of young children include fortified cow's milk and cereals, vitamin and mineral supplements, early introduction of meat and fish, and the inclusion of diverse foods in children's diets.
OLD-SCHOOL STRENGTH: PELEUS AS OLD MAN IN EURIPIDES’ANDROMACHE
Authors: Rimerman Herbert 
Published: July 2022

AbstractThe Peleus of Euripides’Andromachemakes claims puzzlingly incongruous with his decrepit physical state; he threatens physical violence against the much younger Menelaus and denies his advanced age outright in conversation with Andromache. Peleus’ motivations for acting in such a way, Menelaus’ cause for acting as if these claims are true, and the literary or dramatic significance of these affairs, all pose problems which this article addresses, while also offering a first step towards a comprehensive methodology for understanding old age in Euripidean drama. It presents a unified view of old men across several plays, highlighting key patterns of their interaction with old age, and applies this broad perspective to a close analysis of Peleus’ portrayal in theAndromache.It argues that old men in the plays of Euripides can be viewed generally on either side of a dichotomy between giving effective counsel or participating effectively in physical conflict. Peleus subverts this dichotomy by denying the fact of his age throughout, an action which allows him to employ the skill in speaking gained by his old age as a dramatic substitute for direct physical confrontation and to occupy the social role of a younger man in the Greek household.
