Robust adaptive tube tracking model predictive control for piece‐wise constant reference signals
Authors: Peschke Tobias , Görges Daniel 
Published: June 2023

AbstractRobust tracking of piece‐wise constant reference signals for constrained systems with parametric plant uncertainty and additive disturbances is addressed in this paper. The parametric uncertainty is decreased online by set‐membership estimation and a nominal model is updated for improving set‐point tracking. The online estimated parametric uncertainty is used for an online‐determined terminal set which enlarges the set of reachable references close to the system constraints when compared to an offline worst‐case consideration. An artificial target state is introduced which can deviate from the nominal target state. This new target state is used to ensure recursive feasibility for unreachable references and changes in the reference signal. Moreover, a novel “recovery mode” is specified which is deployed in case the new nominal model yields an infeasible control problem. Control algorithms are developed for time‐invariant systems and systems with arbitrarily fast changing plants but known relative bounds. Constraint satisfaction and ‐stability are guaranteed for the proposed algorithms. Controlling the engine load of a self‐propelled work machine is used as a practical example.
The observed mode dependent controller design problem for a class of continuous‐time hidden semi‐Markov jump systems
Authors: Wang Bao , Zhu Quanxin 
Published: June 2023

SummaryThis paper studies the stability analysis and stabilization synthesis problems for a class of continuous‐time jump systems with hidden system modes. To precisely model the switching signals of the considered systems, a novel definition of continuous‐time hidden semi‐Markov process is proposed based on the notions of emission probability and time varying dual‐index transition rate. By virtue of such definition, a dual‐index Lyapunov function is utilized to derive the sufficient stability conditions of the considered systems. By adopting a technology that can decouple the nonlinear terms in the above conditions, the numerically testable existence conditions of the controller for the resulting stabilizing systems are presented. An example is given to illustrate the effectiveness of our results.
Prediction of ACE‐inhibitory and antioxidant peptides from storage proteins of edible seeds and nuts using in silico approaches
Authors: Deka Archana , Saikia Viveeyan 
Published: June 2023

AbstractRecently, plant protein‐derived peptides with diverse bioactivities have gained special attention with regards to health promoting and disease prevention. Among the different plant sources, edible seeds and nuts are known to contribute essential nutritional needs and promote several health benefits. Storage proteins of edible seeds and nuts are known to fulfill the essential nutritional needs and impart several health promoting benefits. In the present study, we attempt to use in silico approaches to divulge storage proteins derived peptides with angiotensin I‐converting enzyme (ACE)‐inhibition and antioxidant properties. In silico hydrolysis of 10 storage proteins using 8 proteases released multiple peptides exhibiting numerous bioactivities. The storage proteins majorly released ACE inhibitory peptides which were subjected for further evaluation (BIOPEP, PeptideRanker, ToxinPred, AllerTOP, and Pepsite2). A total of 25 peptides were considered potential ACE‐inhibitory peptides. Additionally, AnOxPePred webserver was used to evaluate the potential of storage proteins as precursors of antioxidant peptides. As evident from docking analysis (HPEPDOCK), peptides PGCR, GFEWIAFK, GFFYR, and HFR displayed significant interaction with key residues of Kelch‐like ECH‐associated protein 1, a modulator of intracellular oxidant status. Non‐toxic peptide PGCR exhibited both antioxidant and antihypertensive activities and was found to be the most promising peptide. This study opened new avenue for storage proteins of edible seeds and nuts as ingredients in development of nutraceutical formulations.
From a new trigonal cadmium hexacyanoferrate to a Cd Prussian Blue analogue: single‐crystal to single‐crystal transformation and C2H2/CO2 separation capability
Authors: Ou Yangyang , Liang Zihao , Ju Zhanfeng , Yuan Daqiang Q. 
Published: June 2023

AbstractA newly synthesized coordination polymer, [Cd(DMSO)(H2O)]3[Fe(CN)6]2 (CdHCF‐T), based on Cd2+ and Fe(CN)63− ions was prepared in a DMSO/H2O mixed solution and crystalized in the trigonal space group P‐31c. This novel 3D structure presented an interesting single‐crystal to single‐crystal transformation when the coordinated DMSO molecules were replaced by H2O, forming a well‐known Cd Prussian Blue analogue (Cd‐PBA). This occurrence is a rare phenomenon in transition metal hexacyanometallates and may provide a new strategy for obtaining new structures and overcoming the difficulty of growing single crystals of Prussian Blue analogues. Subsequent gas sorption and separation investigations based on the obtained Cd‐PBA were also carried out to evaluate its C2H2/CO2 separation capability.
Thermally stressed thermoelectric microbeam supported by Winkler foundation via the modified Moore–Gibson–Thompson thermoelasticity theory
Authors: Abouelregal Ahmed E. , Marin Marin , Altenbach Holm 
Published: June 2023

AbstractThis article offers the first investigation into the thermoelectric vibration of microscale Euler‐Bernoulli beams resting on an elastic Winkler base. We developed the system of equations for thermoelastic microbeams using elastic basis theory and the generalized Moore–Gibson–Thompson (MGT) thermal transport framework with a single‐phase delay. At the front of the microbeam, a graphene strip connected to an electrical power source was employed to generate heat. In addition, the influence of an ultra‐short‐pulsed laser on the vibration of a microbeam is studied, taking into account its heating effect. The microbeam system variables were analyzed after solving the mathematical equations by applying the Laplace transform technique. Graphs showing how different inputs affect different mechanical fields, such as Winkler substrate stiffness, voltage, electrical resistance, and temperature modulus pulses, are also presented. An increase in the Winkler modulus and the shear modulus of the foundation was found to decrease the amount of deflection and axial deformation in the microbeams. The increased beam stiffness has resulted in this decrease.
Bildung und Bildungsdefizite in Kita und Schule im Rahmen der Coronapandemie
Authors: Walper Sabine , Kuger Susanne 
Published: June 2023

ZusammenfassungDie Kontaktbeschränkungen während der COVID-19-Pandemie haben die Bildungsteilhabe von Kindern und Jugendlichen massiv eingeschränkt, sowohl im Bereich der Kindertagesbetreuung als auch in den Schulen. Im Lockdown brachen v. a. für junge Kinder vielfach die Kontakte zu Freunden und Kita ab. Sowohl die Qualität der Interaktionen zwischen Fachkräften und Kindern als auch die der Kinder untereinander litt unter der Vielzahl der Schutzmaßnahmen, der hohen Fluktuation der anwesenden Kinder und dem Personalmangel. Pandemiebedingte Gruppenschließungen in der Kindertagesbetreuung betrafen verstärkt Einrichtungen mit einem hohen Anteil von Kindern aus sozial benachteiligten Haushalten, und der Anteil der Kinder mit erhöhtem Förderbedarf stieg. Auch Schulen und Familien waren mit den Herausforderungen unzureichender Digitalisierung konfrontiert. Digitaler Unterricht erreichte häufiger ältere und leistungsstärkere Schüler:innen aus sozial bessergestellten Familien. Die Lernzeit hat sich im Distanzunterricht phasenweise durchschnittlich halbiert und sank v. a. bei fehlendem Kontakt zu den Lehrkräften sowie für leistungsschwache Schüler:innen. Nationale und internationale Trenddaten verweisen auf substanzielle Lernrückstände, insbesondere bei Kindern aus sozial benachteiligten Familien mit geringem kulturellen Kapital und aus zugewanderten Familien, wobei die oft ungünstigeren Lernbedingungen und eingeschränkten Unterstützungsmöglichkeiten in diesen Familien vielfach ausschlaggebend waren. Zudem entfielen im Lockdown außerschulische Erfahrungsräume. In der Post-COVID-Bildungsstrategie sollte stärkeres Gewicht auf das ganzheitliche Wohlergehen der Kinder und Jugendlichen gelegt werden, um den erfahrenen Einschränkungen und Belastungen gerecht zu werden.
Performance evaluation of single stand and hybrid solar water heaters: a comprehensive review
Authors: Rahimi-Ahar Zohreh , Khiadani Mehdi , Rahimi Ahar Leile , Shafieian Abdellah 
Published: June 2023

AbstractIn this review, flat plate and concentrate-type solar collectors, integrated collector–storage systems, and solar water heaters combined with photovoltaic–thermal modules, solar-assisted heat pump solar water heaters, and solar water heaters using phase change materials are studied based on their thermal performance, cost, energy, and exergy efficiencies. The maximum water temperature and thermal efficiencies are enlisted to evaluate the thermal performance of the different solar water heaters. It is found that the solar water heaters’ performance is considerably improved by boosting water flow rate and tilt angle, modification of the shape and number of collectors, using wavy diffuse and electrodepositioned reflector coating, application of the corrugated absorber surface and coated absorber, use of turbulent enhancers, using thermal conductive working fluid and nanofluid, the inclusion of the water storage tank, and tank insulation. These items increase the heat transfer area and coefficient, thermal conductivity, the Reynolds and Nusselt numbers, heat transfer rate, and energy and exergy efficiencies. The evacuated tube heaters have a higher temperature compared to the collectors with a plane surface. Their thermal performance increases by using all-glass active circulation and heat pipe integration. The concentrative type of solar water heaters is superior to other solar heaters, particularly in achieving higher water temperatures. Their performance improves by using a rotating mirror concentrator. The integration of the system with energy storage components, phase change materials, or a heat pump provides a satisfactory performance over conventional solar water heaters.

Instability-Induced Origami Design by Topology Optimization

Published: June 2023

AbstractInstability-induced wrinkle patterns of thin sheets are ubiquitous in nature, which often result in origami-like patterns that provide inspiration for the engineering of origami designs. Inspired by instability-induced origami patterns, we propose a computational origami design method based on the nonlinear analysis of loaded thin sheets and topology optimization. The bar-and-hinge model is employed for the nonlinear structural analysis, added with a displacement perturbation strategy to initiate out-of-plane buckling. Borrowing ideas from topology optimization, a continuous crease indicator is introduced as the design variable to indicate the state of a crease, which is penalized by power functions to establish the mapping relationships between the crease indicator and hinge properties. Minimizing the structural strain energy with a crease length constraint, we are able to evolve a thin sheet into an origami structure with an optimized crease pattern. Two examples with different initial setups are illustrated, demonstrating the effectiveness and feasibility of the method.
Centenary (1930–2023) climate, and snow cover changes in the Western Alps of Italy. The Ossola valley
Authors: Stucchi Leonardo , Dresti Claudia , Bocchiola Daniele 
Published: June 2023

AbstractIn this paper, we study centennial trends of climate and snow cover within the Ossola valley, in the Western Italian Alps. We pursue different tests (Mann Kendall MK, bulk, and sequential/progressive MKprog, Linear Regression, also with change point detection, and moving window average MW) on two datasets, namely (i) dataset1, daily temperature, precipitation, snow depth for 9 stations in the area, during 1930–2018, and (ii) dataset2, snow depth and density, measured twice a month (from February 1st to June 1st) for 47 stations during 2007–2023. We also verify correlation with glacier retreat nearby. In dataset1, we highlight a positive trend for minimum temperature with MK, and Linear Regression. Using MKprog/MW, a negative change of snow cover depth, and duration starting from the late 1980s is found. In dataset2, despite the annual variability in snow cover and 2022–2023 winter drought, we assess the maximum snow water equivalent (SWE) to be delayed with respect to maximum snow depth at high altitude (over a month above 2.700 m a.s.l.), highlighting the effect of settling in decreasing snow depth during spring. We also present a formula linking through Linear Regression the Day of the Year of SWE peak to altitude, relevant to assess the onset of thaw season. Due to the high altitude of the stations, and the paradigmatic nature of the Ossola Valley, hosting Toce River, a main contributor to the Lake Maggiore of Italy, our results are of interest, and can be used as a benchmark for the Italian Alps.
Density Functions of Periodic Sequences of Continuous Events
Authors: Anosova Olga , Kurlin Vitaliy 
Published: June 2023

AbstractPeriodic Geometry studies isometry invariants of periodic point sets that are also continuous under perturbations. The motivations come from periodic crystals whose structures are determined in a rigid form, but any minimal cells can discontinuously change due to small noise in measurements. For any integer $$k\ge 0$$

, the density function of a periodic set S was previously defined as the fractional volume of all k-fold intersections (within a minimal cell) of balls that have a variable radius t and centers at all points of S. This paper introduces the density functions for periodic sets of points with different initial radii motivated by atomic radii of chemical elements and by continuous events occupying disjoint intervals in time series. The contributions are explicit descriptions of the densities for periodic sequences of intervals. The new densities are strictly stronger and distinguish periodic sequences that have identical densities in the case of zero radii.
A Model for Evaluating Inequalities in Sustainability
Authors: Camminatiello Ida , Lombardo Rosaria , Musella Mario , Borrata Gianmarco 
Published: June 2023

AbstractOn 25 September 2015, the United Nations General Assembly adopted the 2030 Agenda for sustainable development, which includes seventeen Sustainable Development Goals, among them the 10th Goal aims to reduce inequalities. Convinced of the importance of this goal, in this paper we propose to study the socio-economic determinants which affect the inequalities among the 20 Italian regions by applying a suitable regression model. The socio-economic literature suggests that the most important determinants of inequalities are government spending, income, employment and educational attainment, so we focus our attention on the indicators of the Sustainable Development Goals related to these determinant factors. Given that the number of indicators is extremely high, while the number of observations is low, we consider the partial least squares regression as the most suitable statistical methodology to deal with this dependence modeling.
Wittgenstein on Weyl: the law of the excluded middle and the natural numbers
Authors: Engler Jann Paul 
Published: June 2023

AbstractIn one of his meetings with members of the Vienna Circle, Wittgenstein discusses Hermann Weyl’s brief conversion to intuitionism and criticizes his arguments against applying the law of the excluded middle to generalizations over the natural numbers. Like Weyl, however, Wittgenstein rejects the classical model theoretic conception of generality when it comes to infinite domains. Nonetheless, he disagrees with him about the reasons for doing so. This paper provides an account of Wittgenstein’s criticism of Weyl that is based on his differing understanding of what a general statement over infinite domains consists in. This difference in their conception of generality is argued to be central to the middle Wittgenstein’s overall stance on intuitionism as well. While Weyl (and other intuitionists) reject the law of the excluded middle on grounds of constructivity, Wittgenstein argues that general statements over infinite domains do not express propositions in the first place. The origin of this position as well as its consequences for contemporary debates on generality are further assessed.

Published: June 2023

Abstract
Background
To explore the risk factors of ureteral stricture in transplant kidney and the clinical effects of different treatment methods.

Methods
The 62 patients with transplant kidney ureteral stenosis as the experimental group, and another group of recipients from the same donor as the control group (n = 59 cases). The risk factors for ureteral stricture and the survival rate of transplant kidney were analyzed and compared. The 62 patients were divided into open operation, luminal operation, and magnetic compression anastomosis (MCA) operation group. The effect of the operation and the survival rate of transplant kidney among the three groups were compared.

Results
In our study, we found that the above differences were statistically significant in clinical data such as gender, multiple donor renal arteries, history of infection, and delayed graft function (DGF) between the two groups (P < 0.05). Urinary tract infection and DGF history were the independent risk factors for the development of ureteral stricture. The open operation had the best treatment effect and the survival rate of the transplant kidney, followed by the MCA, the stricture recurrence rate in the luminal operation was the highest.

Conclusion
The ureteral stricture has a negative correlation with the long-term survival rate of the transplant kidney, the curative rate and long-term effect of open surgery are the best, stricture recurrence rate of luminal surgery is high, and it may require multiple operations in the future, the MCA is a new breakthrough and innovation in the treatment of ureteral stricture.
Prostitution und Strafrecht
Authors: Renzikowski Joachim 
Published: June 2023

ZusammenfassungDer Beitrag vermittelt einen Überblick über die Strafvorschriften betreffend die Prostitution. Im Gegensatz zum sog. „Nordischen Modell“ werden die Nachfrage und das Umfeld der Prostitution in Deutschland nicht umfassend kriminalisiert. Stattdessen orientiert sich die strafrechtliche Regulierung an der grundsätzlichen Akzeptanz eigenverantwortlich ausgeübter Prostitution. Kurz: Es geht nicht um den Schutz vor Prostitution, sondern um Schutz in der Prostitution. Gleichwohl fehlt immer noch ein systematisch stimmiges Gesamtkonzept. Abschließend wird der Reformbedarf aufgezeigt.

AbstractThe impact of volcanic airborne products on airway epithelium homeostasis is largely unknown. This study assessed the effects of volcanic Fumarole Condensates (FC) alone or combined with Cigarette Smoke Extracts (CSE) on airway epithelial cells (16HBE and A549). Chemical composition of FC was analyzed by gas chromatography and HPLC. Cells were exposed to FC and IL-33 and IL-8 were assessed. The effects of FC and CSE on cell injury were evaluated assessing cell metabolism/cell viability, mitochondrial stress, cell apoptosis/cell necrosis, and cell proliferation. FC contained: water vapor (70–97%), CO2 (3–30%), acid gases (H2S, SO2, HCl, HF) around 1%. FC increased the intracellular IL-33 but differently modulated IL-33 and IL-8 gene expression and IL-8 release in the tested cell lines. FC without/with CSE: (a) increased cell metabolism/cell viability in 16HBE, while decreased it in A549; (b) increased mitochondrial stress in both cell types. FC with CSE increased cell necrosis in A549 in comparison to CSE alone. CSE reduced cell proliferation in 16HB,E while increased it in A549 and FC counteracted these effects in both cell types. Overall, FC induce a pro-inflammatory profile associated to a metabolic reprogramming without a relevant toxicity also in presence of CSE in airway epithelial cells.
The myth of Muslim violence: Theorizing religion in the war on terror
Authors: Schmiedel Ulrich 
Published: June 2023

AbstractBoth inside and outside the academy, identifications of Islam as a terrorist threat have gained traction during the on-going War on Terror. William Cavanaugh’s conceptualization and critique of what he calls “the myth of religious violence” claims to offer a critique of these identifications. This critique has been influential across a variety of disciplines. In this article, I assess both his more philosophical-critical and his more theological-constructive accounts of religion to argue that Cavanaugh’s myth is, essentially, apologetics. Cavanaugh’s apologetics for the church camouflages the differential treatment of religions during the War on Terror. If it has been about a myth at all, then the War on Terror has been about the myth of Muslim violence. Christianity past and present has condoned and contributed to this very myth. What is needed, then, is a conception and a critique of “religion” that, in contrast to Cavanaugh’s analysis, can account for the significance of Christianity for the differential treatment of religions in the public square, both descriptively and prescriptively.

Published: June 2023

AbstractWith increasing personalized healthcare, fiber-based wearable temperature sensors that can be incorporated into textiles have attracted more attention in the field of wearable electronics. Here, we present a flexible, well-passivated, polymer–nanocomposite–based fiber temperature sensor fabricated by a thermal drawing process of multiple materials. We engineered a preform to optimize material processability and sensor performance by considering the rheological and functional properties of the preform materials. The fiber temperature sensor consisted of a temperature-sensing core made from a conductive polymer
composite of thermoplastic polylactic acid, a conductive carbon filler, reduced graphene oxide, and a highly flexible linear low-density polyethylene passivation layer. Our fiber temperature sensor exhibited adequate sensitivity (− 0.285%/°C) within a temperature range of 25–45 °C with rapid response and recovery times of 11.6 and 14.8 s, respectively. In addition, it demonstrated a consistent and reliable temperature response under repeated mechanical and chemical stresses, which satisfied the requirements for the long-term application of wearable fiber sensors. Furthermore, the fiber temperature sensor sewn onto a daily cloth and hand glove exhibited a highly stable performance in response to body temperature changes and temperature detection by touch. These results indicate the great potential of this sensor for applications in wearable, electronic skin, and other biomedical devices.
