Adaptive safe control for tethered aircrafts with input and output constraints
Authors: Song Mengshi , Zhang Fan , Huang Bingxiao , Huang Panfeng 
Published: July 2023

AbstractIn this article, an adaptive safe control scheme is presented for tethered aircrafts subject to unknown disturbances, input saturations, and deferred asymmetric time‐varying output constraints. By integrating a shifting function into an asymmetric barrier Lyapunov function, the deferred asymmetric time‐varying output constraints are first solved. Then, to eliminate the conflict between input saturations and output constraints, an auxiliary system is designed to enlarge output constraint boundaries when input saturation occurs and the system has no tolerance for output constraints, which ensures system safety. Furthermore, disturbance observers are employed to estimate unknown disturbances. Finally, both theoretical proof and simulation results demonstrate the validity of the proposed control scheme.

AbstractVarious methods have been proposed to analyze national trends of malnutrition and food insecurity; however, these methods often fail to consider regional specificities that drive national food security dynamics. This case study seeks to close this gap through the novel use of participatory causal loop diagrams (CLDs) to analyze the malnutrition crisis and food security dynamics across diverse regions of Guatemala. Stakeholders from six municipalities with divergent food security outcomes, within territories of similar socioeconomic composition, created CLDs by identifying trends, causes, and consequences of malnutrition and food security. Characterizing and assessing these trends, referred to as the food security dynamic, are the primary goals of this paper. Key results include identification of the complex reinforcing relationship between marginalization, education, and health, which affects food insecurity and malnutrition in Guatemala in a nonlinear way. These results elucidate how similar communities can experience divergent food security outcomes and inform locally appropriate solutions. © 2023 The Authors.

Published: July 2023

AbstractForecasting recruitments is a key component of the monitoring phase of multicenter studies. One of the most popular techniques in this field is the Poisson‐Gamma recruitment model, a Bayesian technique built on a doubly stochastic Poisson process. This approach is based on the modeling of enrollments as a Poisson process where the recruitment rates are assumed to be constant over time and to follow a common Gamma prior distribution. However, the constant‐rate assumption is a restrictive limitation that is rarely appropriate for applications in real studies. In this paper, we illustrate a flexible generalization of this methodology which allows the enrollment rates to vary over time by modeling them through B‐splines. We show the suitability of this approach for a wide range of recruitment behaviors in a simulation study and by estimating the recruitment progression of the Canadian Co‐infection Cohort.

AbstractThe growing importance of angelicin derivatives in medicine has prompted us to develop an efficient synthesis strategy for a thienoangelicin derivative, ethyl 8‐methyl‐2‐oxo‐2H‐thieno[2,3‐h]chromene‐3‐carboxylate (MTCE), and investigate its potential applications in spatial probing, therapeutics, and optical sensing. This novel fluorophore, MTCE, exhibits large Stokes shift due to the intramolecular charge separation between the thiophene and coumarin nucleus in the excited state. This indicates its potential for probing spatial polarity. Specific solute‐solvent interactions play a significant role in experimentally calculated excited state dipole moment, including long‐range electrostatic interactions and hydrogen bonding. The multi‐spectroscopic and molecular docking approaches reveal that novel MTCE also interacts in subdomain IIA of BSA by forming ground state complexes following a static quenching mechanism, with the binding constant calculated at ∼104 M−1. The complexation is spontaneous (ΔG ∼−24 kJ mol−1), and enthalpy‐driven (ΔH∼−43 kJ mol−1 and ΔS∼−61 J mol−1), and is primarily mediated by hydrogen bonding and van der Waal forces. Furthermore, the unique fluorescence selectivity of MTCE towards Fe3+ ions under neutral pH conditions, through the formation of a 1 : 1 stoichiometric complex, sets it apart from other common metal ions. Therefore, MTCE holds promising potential for effective utilization in optical sensing applications targeting metal ions.

Published: July 2023

AbstractThe cyclotriphosphazenes, which constitute an important class of inorganic compounds, can show new properties in the medical or technological fields depending on the properties of the substituted organic/inorganic groups. Herein, we aimed to determine electrical and theoretical properties of the nanographene‐doped chalcone derivatives of dioxybiphenyl‐bridged dispiro‐cyclotriphosphazenes. For this aim, a new series of chalcone substituted spiro‐cyclotriphosphazenes (3 a–g) have been synthesized by the reaction of dioxybiphenyl‐bridged dispiro‐cyclotriphosphazene (3) with chalcone derivatives (1 a–g), respectively. Then, nanographene was doped to these spiro‐cyclotriphosphazene 3 a–g using a hydrothermal system. The dielectric constant and loss factor of 4 % graphene‐doped chalcone‐substituted spiro‐cyclotriphosphazene 3 g were determined as 167 and 2147 at 1 kHz, respectively, showing a significant increase compared to compound 3 g. The energy values of HOMO and LUMO orbitals are computed using DFT theory's level of B3LYP/6‐31G(d,p). The FMO's energy gap values for 3 a–g were found to be 7.92, 3.48, 3.26, 3.33, 3.53, 4.03 and 3.75 eV, respectively. Especially at frequencies below 10 kHz, the most striking result was observed for the nanographene‐doped 3 d. While the AC conductivity of 3 d at 1 kHz was 3.87×10−9 S cm−1, the conductivity of the graphene‐doped 3 d was calculated as 5.00×10−6 S cm−1. In addition, DC conductivity measurements were completed as a function of temperature and linearly increasing graphs were obtained with temperature. The activation energies calculated from the slopes of these graphs were 0.293, 0.305, 0.364 and 0.920 eV for 3 c, 3 d, 3 e and 3 g, respectively.

AbstractDiaryl sulfones are known to show diverse pharmacological properties, which calls for an efficient and convenient method for their synthesis. Here, we report a Cu‐catalyzed cross‐coupling method for the synthesis of diaryl sulfones from p‐toluenesulfonyl hydrazide and aryl boronic acids in the absence of an additional ligand. This synthesis procedure is characterized by the use of inexpensive and readily available starting materials, mild reaction conditions, and a broad functionality tolerance. Remarkably, various diaryl sulfones have been synthesized in very short reaction times with moderate to excellent yields.
Sleep reactivity mediates the relationship between sensory‐processing sensitivity and insomnia symptoms severity: A cross‐sectional correlational study
Authors: Pieroni Ilde , Raffone Antonino , Simione Luca 
Published: July 2023

AbstractSensory‐processing sensitivity (SPS) is a temperamental trait that describes individual differences in sensitivity to environmental stimuli. Previous studies have shown that highly sensitive individuals are more vulnerable to stress and to sleep‐related difficulties. In light of this evidence, we hypothesized that SPS is associated with an increase in insomnia symptoms and that this correlation would be mediated by increased perceived stress and sleep reactivity. To test this hypothesis, we conducted a cross‐sectional study on 358 adults who completed a survey that included self‐report measures of sensitivity, perceived stress, sleep reactivity, and insomnia symptoms. Correlation analysis revealed that SPS was positively related to both stress‐related and sleep‐related variables. We then conducted a mediation analysis, which revealed that SPS was positively related to insomnia symptoms and that this relationship was fully mediated by sleep reactivity but not mediated at all by perceived stress. The current findings suggest that sleep reactivity may contribute to the development of insomnia symptoms in highly sensitive individuals. Therefore, these results suggests that sleep reactivity should be assessed in highly sensitive individuals and that it could be important to evaluate and further study this relationship.

Published: July 2023

AbstractThe rapidly developed metal halide perovskite light‐emitting diodes (PeLEDs) are considered as a promising candidate for next‐generation display and illumination, but the unbalanced charge transport is still a hard‐treat case to restrict its efficiency and operational stability. Here, a high curvature PEDOT:PSS transport layer is demonstrated via the self‐assembly island‐like structures by the incorporation of alkali metal salts. Benefiting from the dielectric confinement effect of the high curvature surface, the modified CsPbBr3‐based PeLEDs present a 2.1 times peak external quantum efficiency (EQE) from 6.75% to 14.23% and a 3.3 times half lifetime (T50) from 3.96 to 13.01 h. Besides, the PeLEDs show high luminance up to 44834 cd m−2. Evidently, this work may provide a deep insight into the structure‐activity relationship between the micro‐structures at the PEDOT:PSS/perovskite interface and the performance of PeLEDs, and crack the codes for ameliorating the performance of PeLEDs via interfacial micro‐structured regulation.

AbstractBackgroundNo studies determined the use of spineless cactus cladodes in camel diets.ObjectivesThe effect of replacing the main energy source in camel diets with fresh spineless cactus cladodes on growth performance was determined. Furthermore, the ability of morphology to predict cladodes yield was determined.MethodsA prediction model of spineless cactus cladode weight based on cladode volume was developed. Three cladodes per plants were randomly selected from 100 plants. Weight and volume were then recorded for each cladode. Sixteen male camel calves (196 ± 18.2 kg live weight and 430 ± 5.55 days of age) were allotted to treatments, control (conventional camel fattening diet based on cotton seed hulls, cereal grains and agro‐industrial by‐products) or cactus (barley and maize grains in the control diet were replaced totally by fresh cactus cladode on dry matter basis). The study contained a 100‐days growth trial and a 21‐day digestibility trial (15 days of adaptation and 7 days of faeces collection). Blood samples were collected monthly from each animal.ResultsCactus cladode volume predicted the dry weight with a high accuracy (prediction error = 3.5%). Nutrient intake and nutrient digestibility did not significantly differ among the dietary treatments (p > 0.05). The treatment significantly decreased feed conversion ratio by 1.52 points (p < 0.05). All blood parameters were within the normal range of dromedary camels.ConclusionsSpineless cactus cladode is a potential replacement to the conventional energy sources in dromedary camel diets.
Interaction among interfacial offset cracks in composite materials under the anti‐plane shear loading

Published: July 2023

AbstractThe present article considers an anti‐plane stress problem of three cracks at different orthotropic materials' interfaces. According to the geometry of the problem, the governing equations and mixed boundary conditions have been formulated. Fourier integral transformation is used to convert the mixed boundary value problem into dual integral equations, which gives two equations containing infinite series. The investigation of the problem concerning anti‐plane cracks subjected to static loadings is done with the help of the Schmidt method to satisfy the given boundary conditions. The difference in displacements is expanded to proceed further in the problem, which becomes zero outside the cracks. Numerical computations are carried out for the graphical representation of stress intensity factors (SIFs) at all cracks' tips. The Interaction among the cracks as those are in close proximity to each other or move away are represented pictorially. Detailed numerical results and discussion are done for the considered materials, which include aluminium, epoxy and graphite epoxy. The novelty of the present article is the numerical analysis and pictorial presentation of SIFs at the tips of interfacial offset parallel cracks for various crack lengths and normalised heights for different combinations of materials. The authors have obtained variations in SIFs for the cracks at the interfaces of dissimilar composite materials.

E-strings, F4, and D4 triality
Authors: Sakai Kazuhiro 
Published: July 2023

Abstract
We study the E-string theory on ℝ4 × T2 with Wilson lines. We consider two examples where interesting automorphisms arise. In the first example, the spectrum is invariant under the F4 Weyl group acting on the Wilson line parameters. We obtain the Seiberg-Witten curve expressed in terms of Weyl invariant F4 Jacobi forms. We also clarify how it is related to the thermodynamic limit of the Nekrasov-type formula. In the second example, the spectrum is invariant under the D4 triality combined with modular transformations, the automorphism originally found in the 4d 𝒩 = 2 supersymmetric SU(2) gauge theory with four massive flavors. We introduce the notion of triality invariant Jacobi forms and present the Seiberg-Witten curve in terms of them. We show that this Seiberg-Witten curve reduces precisely to that of the 4d theory with four flavors in the limit of T2 shrinking to zero size.
Oscillon spectroscopy

Published: July 2023

Abstract
The sine-Gordon model in 3+1 dimensions is known to admit two oscillons of different energy and frequency but comparable lifetime. We show that the oscillon spectrum includes more spherically symmetric “states”. We identify new high-amplitude oscillons by allowing the field profile to have a number of nodes. For each number of nodes, we find 2 states with a comparable lifetime to the nodeless ones. Oscillons with nodes are, however, unstable to non-spherical perturbations and so their lifetime is significantly reduced. Interestingly, these states are seen to fragment into a collection of nodeless oscillons. The heavy nodeless oscillon is quite remarkable: despite its energy, it is stable against fragmentation. Moreover, it has considerably small oscillation frequency, meaning that it can be interpreted as a rather relativistic bound state.

, covering the time frame 2003 to 2019 without gaps, and including monthly uncertainty quantification. GLWS2.0 was derived by assimilating monthly GRACE/-FO mass change maps into the WaterGAP global hydrology model via the ensemble Kalman filter, taking data and model uncertainty into account. TWSA in GLWS2.0 is then accumulated over several hydrological storage variables. In this article, we describe the methods and data sets that went into GLWS2.0, how it compares to GRACE/-FO data in terms of representing TWSA trends, seasonal signals, and extremes, as well as its validation via comparing to GNSS-derived vertical loading and its comparison with a version of the NASA Catchment Land Surface Model GRACE Data Assimilation (CLSM-DA). We find that, in the average over more than 1000 stations globally, GLWS2.0 correlates better with GNSS observations of vertical loading at short-term, seasonal, and long-term temporal bands than GRACE/-FO. While some differences exist, overall GLWS2.0 agrees reasonably well with CLSM-DA in terms of TWSA trends and annual amplitudes and phases.Highlights

AbstractThe aim of this study was to re-evaluate fluoroquinolone (FQ) use in treatment by analyzing the consumption of FQ and the resistance levels of selected Gram‑negative bacilli, as well as Neisseria gonorrhoeae and Mycobacterium tuberculosis complex in EU/EEA countries and in Poland between 2016 and 2021. Data from ECDC surveillance systems EARS-Net, Euro-GASP, and the European Tuberculosis Surveillance Network were included in the description of pathogen resistance. And the ESAC-Net project for determining FQ consumption. In over half of the EU/EEA countries, the consumption of fluoroquinolones decreased in both the community sector and the hospital sector between 2016 and 2021. The prevalence of FQ-R Escherichia coli, Klebsiella pneumoniae, Acinetobacter spp., Mycobacterium tuberculosis complex, and Neisseria gonorrhoeae exceeded 20%. The prevalence of fluoroquinolone-resistant (FQ-R) Pseudomonas aeruginosa in EU/EEA countries was less than 20% except for 2017. In most EU/EEA countries, the use of FQ has reduced in last years, except for countries like Poland where FQ were an overused group of antibiotics in the treatment of various types of infections. Fluoroquinolones, as life-saving antibiotics in severe infections, should be withdrawn from empirical treatment in Poland and in countries with a high prevalence of FQ-R microorganisms.
