Integrated control‐structure co‐design for flexible manipulators
Authors: Bastos Guaraci 
Published: July 2024

AbstractThis work aims to develop a methodology for the integrated control‐structure design of flexible multibody systems. Such an issue is linked to a generalization of the inverse dynamics problem, where both the feedforward control and mechanical parameters are designed to perform a desired trajectory optimally. The resulting constrained motion is aimed at improving the dynamic performance of the system, which is underactuated, with less power demand but possible elastic deformation. Stable inversion methods are required to deal with the internal dynamics related to underactuation. The proposed methodology is based on the optimal control theory. For illustrative purposes, we considered a fully actuated linear time‐invariant (LTI) system, establishing the integrated design results in a least‐squares homogeneous system and in an optimization problem. An additional formulation is proposed for the integrated design of the flexible multibody systems, where both a multi‐criterion optimization and a scalarized problem of a corresponding nonlinear programming problem are formulated to deal with the unstable zero‐dynamics related to non‐minimum phase systems and nonlinearity. The numerical simulation of an underactuated two‐masses‐spring‐damper system and a flexible robotic manipulator in planar motions are used for validation. Finally, the beneficial aspects of the integrated design are analyzed.

Published: July 2024

ABSTRACTThe purpose of this review is to provide an overview of the perinatal outcomes of fetuses who underwent fetal surgery for the management of Amniotic Band Syndrome (ABS). A systematic review of studies reporting on the perinatal outcome of fetuses undergoing fetoscopic release of amniotic bands according to the (PRISMA) guidelines was performed. The MEDLINE, Embase, Scopus, and Cochrane Library databases were systematically searched. In total, 17 studies reporting 37 cases of ABS that underwent amniotic band release by fetoscopy were included. The median gestational age at which fetal surgery was performed was 22 weeks (range 18–29 weeks). PPROM occurred in 51.3%, while fetal survival reached 89.2%. The success of fetal surgery was 75.7% in preserving and maintaining the functionality of the affected limb. Fetoscopic release of amniotic bands can preserve the affected limb and its function in cases of ABS and prevent fetal death in cases of ABS involving the umbilical cord. Further studies are needed to determine the optimal criteria for selecting patients who can benefit from fetal surgery, considering that it is an intervention that is not free of perinatal complications.

ABSTRACTImportanceNutrition is associated with neurodevelopment. Infants at high risk of cerebral palsy (CP) usually suffer from undernutrition, yet the relationship between nutritional status and neurodevelopmental levels is unclear.ObjectiveTo describe the nutritional status characteristics of infants at high risk of CP, and to explore the relationship between neurodevelopmental levels and nutritional status.MethodsThis single‐center cross‐sectional study enrolled infants at high risk of CP, with corrected age from 0 days to 12 months. Weight and height were measured and calculated into z‐scores, which were used to classify the nutritional status based on the World Health Organization growth charts and American Society for Parenteral and Enteral Nutrition standards. The Bayley Scales of Infant and Toddler Development were used to evaluate the developmental levels of gross motor, fine motor, cognition, receptive communication, and expressive communication.ResultsA total of 479 infants at high risk of CP were recruited, with 43.4% classified as undernutrition. Compared to those with normal neurodevelopment, the odds of moderate and severe undernutrition were about 1.8 and 3.9 times higher in gross motor delay, 2.2 and 3.1 times higher in fine motor delay, 2.5 and 9.4 times higher in cognition delay, 2.2 and 3.9 times higher in receptive communication delay, and 3.0 and 5.6 times higher in expressive communication delay. There were significant positive correlations between nutritional status and neurodevelopmental levels (P < 0.001).InterpretationUndernutrition and neurodevelopmental delays are prevalent among infants at high risk of CP. Worse nutritional status was correlated with lower neurodevelopmental levels.

Published: July 2024

ABSTRACTImportanceViral encephalitis is one of the main causes of the perisylvian syndrome, which can cause damage to children's language‐speech, feeding, and swallowing functions. Comprehensive assessment of language‐speech and swallowing function and comorbidity research on these children will help children's rehabilitation workers to better understand the disease and strengthen the systematic management of comorbid disorders.ObjectiveTo describe speech and language pathology and the occurrence of comorbid disorders in children with perisylvian syndrome induced by viral encephalitis.MethodsTwenty‐two children with acquired perisylvian syndrome were recruited in this study. Language and speech functions, including oral motor function, swallowing function, language ability, and dysarthria were assessed in these patients. Craniocerebral magnetic resonance imaging (MRI), electroencephalogram examination, and intelligence evaluation were performed to determine brain lesions and comorbid disorders.ResultsAll children exhibited different degrees of oral movement, dysphagia, and speech and language disorders. There was a significant difference between expressive and receptive language ability (P < 0.05). There were 10, 8, and 12 children who had an intellectual disability, limb disability, and epilepsy, respectively. In addition to the damage of the peri‐tegmental cortex found in MRI, thalamus lesions occurred in 19 cases and white matter involvement in six cases.InterpretationChildren with acquired perisylvian syndrome caused by viral encephalitis are characterized by persistent pseudobulbar dysfunction, speech and language impairment, and orofacial diplegia. They have a high probability of secondary epilepsy and are prone to motor and cognitive impairment, which need systematic management.
Reducing the moisture susceptibility of recycled hot‐mix asphalt mixture with composite modification technology

Published: July 2024

AbstractStyrene–butadiene–styrene block copolymer (SBS)‐modified asphalt is a key material for constructing recycled hot‐mix asphalt mixtures (RHMAs). However, these mixtures still risk insufficient moisture stability. To this end, this study investigates the feasibility of asphalt composite modification technology to enhance RHMA performance. SBS, high‐viscosity agent (HVA) and crumb‐rubber materials (CRM) were used to prepare SBS‐HVA‐ and SBS‐CRM‐modified asphalt, with SBS‐modified asphalt as the control group, and the adhesion properties of the asphalt were evaluated using surface free energy tests. RHMAs with 50% reclaimed asphalt pavement were then prepared with each type of modified asphalt. The moisture susceptibility of these mixtures was analyzed using moisture‐induced sensitivity, freeze–thaw splitting and immersion Marshall tests. It was found that HVA significantly enhanced the adhesion of SBS‐modified asphalt under dry conditions, while CRM had a minimal effect. Compared to RHMA with SBS‐modified asphalt, HVA and CRM additives are crucial for enhancing the moisture stability of RHMA in the immersion Marshall test. However, CRM does not improve the moisture stability of RHMA in the moisture‐induced sensitivity and freezing–thaw splitting tests. From the conducted study, it can be proposed that SBS and HVA composite‐modified asphalt can be utilized in RHMAs to achieve higher moisture stability. © 2024 Society of Chemical Industry.

ABSTRACTPurposeMerozoites are the only extracellular form of blood stage parasites, making it a worthwhile target. Multiple invasins that are stored in the merozoite apical organelles, are secreted just prior to invasion, and mediates its interaction with RBC. A comprehensive identification of all these secreted invasins is lacking and this study addresses that gap.Experimental DesignPf3D7 merozoites were enriched and triggered to discharge apical organelle contents by exposure to ionic conditions mimicking that of blood plasma. The secreted proteins were separated from cellular contents and both the fractions were subjected to proteomic analysis. Also, the identified secreted proteins were subjected to GO, PPI network analysis, and AI‐based in silico approach to understand their vaccine candidacy.ResultsA total of 63 proteins were identified in the secretory fraction with membrane and apical organellar localization. This includes various MSPs, micronemal EBAs and rhoptry bulb proteins, which play a crucial role in initial and late merozoite attachment, and majority of them qualified as vaccine candidates.Conclusion and Clinical RelevanceWe, for the first time, report the secretory repertoire of merozoite and its status for vaccine candidacy. This information can be utilized to develop better invasion blocking multisubunit vaccines, comprising of immunological epitopes from several secreted invasins.

Published: July 2024

AbstractWe show that the Raychaudhuri equation (RE) remains form invariant for certain solutions of scalar fields whose Lagrangian is non‐canonical and of the form , with and the potential. Solutions exist for both homogeneous and inhomogeneous fields that are like inflatons. Certain recent observations indicate that the cosmos is inhomogeneous and thus their results are in sync with latest observations. So the RE can accommodate primordial inhomogeneities as well as cosmologically relevant scenarios.
Approximate solutions for diatomic molecules under combined potentials in a global monopole and Aharonov–Bohm flux field
Authors: Nayek Sujay Kumar , Dutta Barnali , Pradhan Bhumika 
Published: July 2024

AbstractBound state energy eigensolutions of nine different diatomic molecules, specifically, , TiH, , CO, NO, ScH, CrH, HCl and LiH, placed in a point‐like global monopole, have been calculated by solving the time‐independent Schrödinger equation (SE). The molecules are confined by the Aharonov–Bohm (AB) flux field and the interaction potential among the charged particles is governed by the combined screened modified Kratzer potential (SMKP) plus Hulthén potential model. Three other special cases of the interaction potential have also been discussed here. Asymptotic iteration method has been used for the mathematical calculations. It is difficult to solve the SE exactly for any non‐zero values of the azimuthal quantum number due to the presence of the centrifugal barrier term. The well‐known Pekeris approximation technique for the terms and has taken into consideration for the purpose of performing numerical computations connected to an arbitrary state. The outcomes of this study are in reasonable agreement with the results of previous research on SMKP, Kratzer‐Fues potential, and modified Kratzer potential in the Minkowski space. It is observed that the energy spectra of the diatomic molecules suffer considerable change due to the effects of the background AB‐flux field and topological defect parameter.
Output feedback finite‐time boundary control for an unstable heat PDE with spatially varying coefficients
Authors: Ghaderi Najmeh , Mojallali Hamed 
Published: July 2024

AbstractThis article studies the output feedback finite‐time boundary control for unstable heat systems with the spatially varying coefficient. First, a finite‐time observer with switched gains under a state‐dependent switching law is designed in order to estimate the states of the system in a finite‐time only exerting one displacement boundary measurement. Next, an observer‐based linear finite‐time control is planned. Namely, a linear switched control under a state‐dependent switching law is proposed to vanish every solution of an unstable heat partial differential equation with spatially varying coefficients in a finite time. We also present explicit forms for the proposed observer gains and output feedback finite‐time controller. Finally, some numerical simulations are provided to confirm the theoretical results.
From muscular to dexterous: A systematic review to understand the robotic taxonomy in construction and effectiveness
Authors: Gao Yifan , Shu Jiangpeng , Xia Zhe , Luo Yaozhi 
Published: July 2024

AbstractThis work presents an investigation of robotic technologies' effectiveness in construction activities. Sixty‐four highly relevant publications were identified from the database. By systematically reviewing the publications, the secondary data that are of interest to the review theme were retrieved and further evaluated. It is found that robotic technologies for automated construction is a growing field, where the taxonomy of robot was reflected in a diversified manner in the existing studies, ranging from the muscular guy—robotic manipulator—to the dexterous ones—unmanned aerial vehicle, autonomous mobile robot, automated guided vehicle, autonomous construction machinery and quadruped robot. In addition, the existing studies have provided substantial evidence to reveal the robotic technologies' effectiveness against traditional human methods in construction scenarios, and the measures for effectiveness consisted of productivity, precision, and success rate. With the evidence, it seems that the construction sector could benefit from robotic technologies to achieve intelligent workflows. Furthermore, based on the existing knowledge foundation in the current literature, a theoretical framework for future research direction is proposed. The framework envisages the integration of large models with construction robots to address operational inefficiencies, reduce costs, and simplify management.
Competing with the platform: Complementor positioning and cross‐platform response to entry
Authors: Kapacinskaite Aldona , Mostajabi Ahmadreza 
Published: July 2024

AbstractResearch SummaryThis study contrasts traditional entry dynamics with platform owner entry into a complementor market and examines cross‐platform complementor response to competition with the platform. Generalists experience low repositioning cost and are more likely to shift effort away, while specialists focus their effort on the focal platform. We examine Apple's “Files” app entry and find support for our hypotheses: generalists shift effort toward the competing platform, while specialists double down on the focal platform. Moreover, empirically comparing Apple's entry with that of other large firms, we find that only the platform owner elicits a strong complementor response. This article contributes to the competitive and corporate strategy literatures, underscoring how complementor heterogeneity affects cross‐platform allocation of effort when the platform owner becomes a competitor in complementor spaces.Managerial SummaryGiven the growing managerial and regulatory interest in competitive arenas on digital platforms, we analyze how firms respond to competition with the platform owner. We hypothesize that platform‐enabled firms (complementors) with an outside option—those who also operate on a different platform—reposition, while firms only focused on a single platform double down. Examining the case of the “Files” app on Apple's App Store, we find support for these predictions. We also study other large firm entries on App Store (by Microsoft and SanDisk), but do not observe a meaningful response by complementors. We describe how market entry by the platform owner differs from traditional entry and argue stakeholders may benefit from a deeper understanding of the unique nature of competing with a platform.
Analytical solution of two non‐identical edge cracks in an infinite strip under anti‐plane shear wave
Authors: Panja Sourav Kumar , Alam Samim , Mandal Subhas Chandra 
Published: July 2024

AbstractThis article presents an extensive analytical solution addressing the interaction between two non‐identical edge cracks in an infinite orthotropic strip under anti‐plane shear waves. Most studies assume identical cracks or single edge crack in a strip, but this research breaks new ground by considering cracks of different sizes. By incorporating mixed‐type boundary conditions, the study derives dual integral equations. These equations are then transformed into a singular integral equation of Cauchy type with the aid of a trial solution and contour integration technique. The singular integral equation is further converted into a system of integral equations, which are solved numerically utilizing Jacobi polynomials. The obtained solutions are utilized to derive expressions for the stress intensity factor (SIF) and crack opening displacement (COD) at the crack tip using Krenk's interpolation formulae. The derived results are presented graphically and compared against existing solutions for single edge crack and symmetric edge cracks in static scenario.
Building Digital Capacity in the Face of Crisis: Exploring the Impact of Municipal Amalgamations in an Intergovernmental Context
Authors: Torfs Inke , Wayenberg Ellen 
Published: July 2024

AbstractLocal governments play a crucial role in crisis response and policymaking, necessitating robust digital capacity to effectively tackle complex challenges. To meet the contemporary demand for building local capacity, especially in the digital domain and in anticipation of future crises, European countries are increasingly pursuing municipal amalgamations. Despite this prevalent trend, the impact of such amalgamations remains uncertain, lacking sufficient empirical research and neglecting intergovernmental relations. This chapter addresses this gap by (1) assessing the impact of municipal amalgamations on local digital capacity and (2) scrutinizing their intergovernmental context. Employing Jane Fountain’s Technology Enactment Framework, we propose a research model for an in-depth analysis of digital capacity evolution in a Flemish amalgamated municipality from 2017 to 2022. The results suggest that a municipal amalgamation can indeed serve as a valuable means to enhance local digital capacity, but sustained intergovernmental support remains essential. While various types of intergovernmental relations are feasible, respondents express a preference for a more centralized approach over the prevailing multilayered approach. This preference arises from an anticipation of swifter policy responses aligned with the dynamic evolution of technology and a more coordinated strategy that harmonizes local internal efforts with the intergovernmental initiatives.
Towards Place-Sensitive Crisis Management? Pandemic Policies in Five Nordic Countries
Authors: Baldersheim Harald , Haug Are Vegard 
Published: July 2024

AbstractThe policy issue in focus in this chapter is the local implementation of covid management policies during the pandemic 2020–2022 in the five Nordic countries. More specifically, we seek to determine the extent to which national policies were shaped and implemented in ways that took account of variations in local contexts, such as, for example, varying levels of contagion, different demographic structures, economic needs, access to medical treatment, et cetera. The analysis is based on data on how 411 mayors experienced the Covid policies of the Nordic countries and thus presents a bottom-up perspective on IGR in times of uncertainty and turbulence. The main hypothesis is that the mayors’ experiences of IGR significantly depend upon their access to national levels of decision-making. The hypothesis was largely confirmed, but the analysis also demonstrated that a series of other factors influenced IGRs as experienced by mayors, such as political affiliation or centre–periphery contrasts, while formal institutional variations did not matter as much as expected.
Intergovernmental Relations in Digitalization Policy: German Tax Administration Between Centralization and Decentralization
Authors: Wehmeier Liz Marla 
Published: July 2024

AbstractDespite the high hopes associated with public sector digitalization, especially in times of crisis, it does not yet hold up to its potential. Both the negotiation and implementation of digitalization policy presents a challenge for all levels of government, requiring extensive coordination efforts. In general, there are conflicting views if more centralized or decentralized policy processes are more effective for coordination—a tension further exacerbated in the context of digitalization policy within multilevel systems, where the imperative of standardization collides with decentralization forces inherent in federalism.Based on the analysis of expert interviews (n = 29), this chapter examines how digitalization policy in the context of the German federal intergovernmental relations context is located and negotiated, and how this relates to local policy implementation. Focusing on the decentralized German tax administration as a case study, the analysis reveals a shift from a conflicted to a multi-layered policy process, underpinned by a mechanism of “concentration without centralization.” Strategic and operational competencies are bundled in an institutionalized and legally regulated network for digitalization to achieve necessary standardization of digital infrastructure. Furthermore, the research emphasizes the influence of intergovernmental relations on local implementation and the associated challenges and opportunities.
