Finite‐horizon H∞ output fault‐tolerant consensus for multi‐agent systems with switching topology and deception attacks
Authors: Chen Yang‐Jie , Li Jian‐Ning , Wu Lan 
Published: January 2023

AbstractThis article investigates the output fault‐tolerant consensus problem for multi‐agent systems with switching topology and deception attacks. In order to reduce the effects of switching topology, the differences between topologies can be modeled as topology uncertainties. In practice, the deception attack may occur in a random way and assumed to satisfy Bernoulli distributions. The purpose of this research is to design an output fault‐tolerant controller such that, in the presence of switching topology, actuator faults, and deception attacks, the finite‐horizon output fault‐tolerant consensus can be achieved under a prespecified performance. An initial‐state‐based performance requirement is constructed, and this bypasses the need for the zero initial condition in the conventional theory. After this, the controller gains are computed by employing an iterative linear matrix inequality scheme. Finally, a numerical example is provided to show the effectiveness of the proposed methods.

AbstractA highly sensitive and selective electrochemical biosensor for catechol (CC) detection was developed by immobilizing tyrosinase (TYR) on a glassy carbon electrode (GCE) modified with sulfide minerals (SFMs) in the co‐adsorption of acridine orange (AO). The sensor employed natural SFMs as the substrate material and utilized AO as a molecular recognition probe to create synergy effect for TYR to detect catechol. The developed TYR/AO/SFMs/GCE biosensors were characterized by scanning electron microscope, energy dispersive analysis of X‐rays spectroscopy, X‐ray diffraction spectra, X‐ray fluorescence, and electrochemical analysis. The results show that the sensors have excellent electrochemical activity for the detection of catechol (CC) under optimized conditions. The linear ranges were 0.1–50 μM, 0.1–10 μM, 0.1–50 μM and 0.1–100 μM for galena, pyrite, chalcopyrite and sphalerite, respectively, with the detection limits of 1.18 μM, 0.29 μM, 0.54 μM and 0.68 μM, respectively. The sensors also have good reproducibility, stability, repeatability and anti‐interference ability. AO is essential to increase the adsorbed amount and provides suitable orientation of the adsorbed TYR on these sulfide minerals’ surfaces. In consideration of cost‐effective and rich resources of sulfide minerals, easily physical adsorption method, combination of organic dye, minerals and enzymes, this strategy paves a new way to design other novel electrochemical biosensors.

AbstractAiming at the problems of the graphene oxide (GO) membrane‘s water swelling and low ion selectivity, a two‐step reduction method was designed to prepare the interlayer positive charge modified two‐step reduced graphene oxide (TS‐rGO) membrane. Modified stable polyamino molecules onto GO, such as ethylenediamine (EDA), piperazine (PIP) and melamine (MA), provided the membrane interlayer with positive charge to enhance ion selectivity and maintained the stability of the interlayer channel at the same time. The moderate reduced graphene oxide (RGO) membrane was obtained by two‐step reduction process of hydrothermal reduction and heat treatment reduction, which enhanced the stability in water environment and increased the water flux. The permeability of TS‐rGO membrane, represented by PIP‐rGO, to monovalent metal ions (K+, Na+, Li+) was similar to that of GO membrane, but its rejection effect on trivalent metal ion (the penetration rate of La3+ is as low as 4.65×10−5 mol m−2 h−1.) was enhanced by nearly two orders of magnitude. The TS‐rGO membrane could have high ion selectivity, high low‐valent ion permeability, and high water flux simultaneously. In the process of ion permeation, due to the successful modification of interlayer positive charge, the charge effect and size effect synergistically improve the ion selectivity of TS‐rGO membrane.

AbstractElectrostatic capacitors are emerging as a highly promising technology for large‐scale energy storage applications. However, it remains a significant challenge to improve their energy densities. Here, an effective strategy of introducing non‐isovalent ions into the BiFeO3‐based (BFO) ceramic to improve energy storage capability via delaying polarization saturation is demonstrated. Accordingly, an ultra‐high energy density of up to 7.4 J cm−3 and high efficiency ≈ 81% at 680 kV m−1 are realized, which is one of the best energy storage performances recorded for BFO‐based ceramics. The outstanding comprehensive energy storage performance is attributed to inhibiting the polarization hysteresis resulting from generation ergodic relaxor zone and random field, and generating highly‐delayed polarization saturation with continuously‐increased polarization magnitudes with the electric field of supercritical evolution. The contributions demonstrate that delaying the polarization saturation is a consideration for designing the next generation of lead‐free dielectric materials with ultra‐high energy storage performance.

Published: January 2023

AbstractMetal organic framework (MOF) glasses are a coordination network of metal nodes and organic ligands as an undercooled frozen‐in liquid, and have therefore broadened the potential of MOF materials in the fundamental research and application scenarios. On the road to deploying MOF glasses as electrocatalysts, it remains several basic scientific hurdles although MOF glasses not only inherit the structural merits of MOFs but also endow with active catalytic features including concentrated defects, metal centers and disorder structure etc. The research on the ionic conductivity, catalytic stability and reactivity of MOF glasses has yielded scientific insights towards its electrocatalytic applications. Here, we first comb the history, definition and basic properties of MOF glasses. Then, we identify the main synthetic methods and characterization techniques. Finally, we advance the potentials and challenges of MOF glasses as electrocatalysts in furthering the understanding of these themes.

AbstractBackgroundComputed tomography (CT) is considered the first‐line imaging modality for human patients with suspected multiple myeloma (MM). Recently the diagnostic criteria for human MM have been updated.ObjectivesTo describe and provide a baseline of the CT features and distribution of osseous lesions in dogs diagnosed with MM and to describe the change of initial osseous lesions after the start of treatment in a subset of dogs.MethodsSingle‐centre, retrospective, descriptive, case series. Dogs were included when they met the updated MM criteria and if a staging CT was performed at the time of diagnosis and prior to initiation of treatment. When available, change of osseous lesions was assessed on serial imaging studies.ResultsThirteen dogs met the inclusion criteria. All dogs had involvement of the axial skeleton and 9/13 (69%) had concurrent involvement of the appendicular skeleton. Large (≥1 cm), lytic, ‘punched out’ or expansile bony lesions and regions of permeative lysis were most common and mainly affected the vertebral column. Discrete intramedullary soft tissue attenuating lesions of the proximal appendicular skeleton were observed in 8/13 dogs (61%) and bilateral involvement of both humeri and femurs was seen in 4/9 dogs (44%). A subset of dogs underwent serial imaging and progressive replacement of the contrast‐enhancing lesions with fat attenuating tissue was observed for all dogs, corresponding with clinical improvement.ConclusionsThis case series provides a baseline knowledge of the initial and follow‐up CT features in dogs diagnosed with MM based on updated criteria.

AbstractAn 8‐year‐old Miniature Poodle presented with chronic sneezing and unilateral epistaxis. A left‐sided intranasal mass was identified on computed tomography. 18F‐fluorodeoxyglucose (FDG) positron emission tomography (PET) was performed to evaluate the metabolic activity of the mass. The intranasal mass showed mildly increased 18F‐FDG uptake. The maximal and mean standardized uptake values (SUVs) of the mass were 3.4 and 2.6, respectively. The maximal SUV of the mass/mean SUV of the normal liver was 2.5. The 7‐cm soft, pink mass was easily removed through rhinoscopy, with subsequent dramatic improvement in clinical signs. Histopathological and immunohistochemical analyses determined that the mass was an intermediate‐grade malignant peripheral nerve sheath tumour (PNST). This is the first report of 18F‐FDG PET findings in a PNST in dogs.

AbstractBackgroundIn mynahs with foreign body ingestion, delayed diagnosis increases the risk of poor outcomes.ObjectiveThe aim of this study was to evaluate various radiologic features on plain and contrast radiographs in mynahs for assessing the presence of ingested foreign bodies.MethodsIn our cross‐sectional study, a total of 41 mynahs were included. The diagnosis was made by history, surgery, excision by forceps or excretion in the faeces. Overall, 21 mynahs were considered not to have a foreign body in their gastrointestinal tract. Plain and post‐contrast [oral administration of barium sulphate colloidal suspension of 25% weight/volume (20 mg/kg)] lateral and ventrodorsal radiographs from the cervical and coelomic cavity were taken. Different parameters including oesophageal, proventricular, and small intestinal diameters and opacities were assessed. Image evaluation was performed by two national board‐certified radiologists blinded to the final diagnoses.ResultsThe inter‐ and intra‐observer reliabilities of the diagnostic features were significant (p < 0.001). The diagnosis of the foreign body was highly accurate [90.2% (95% CI: 76.9%, 92.3%)] with the sensitivity, specificity, and area under the representative characteristic curve of 90.0%, 90.5%, and 0.93%, respectively for plain radiographs. The size and opacity of the oesophagus, proventriculus, and intestinal loops as well as serosal details were significantly different between mynahs with and without foreign body intake (p < 0.05).ConclusionsLateral and ventrodorsal plain radiographs are highly reliable for diagnosing the presence of non‐opaque obstructing objects in the gastrointestinal tract of mynahs. Attention should be paid to the size and opacity of the oesophagus, extension, and opacity of the proventriculus, segmental opacity of intestinal loops, and decrease in serosal details.
Changing behavioral responses to heat risk in a warming world: How can communication approaches be improved?
Authors: McLoughlin Niall , Howarth Candice , Shreedhar Ganga 
Published: January 2023

AbstractHeat risks, such as those associated with heatwaves, are increasing in frequency, severity, and duration due to climate change. The ways in which people around the globe perceive and respond to heat risks are now of great importance to reduce a range of negative health outcomes. A growing body of literature aims to assess the factors that influence people's behaviors in relation to heat risks. This research can inform better interventions, such as improved communications approaches, that attempt to facilitate adaptive behavioral responses to such risks. This review focuses on how insights from behavioral and attitudinal studies about heat risk responses can inform communication approaches. These insights are organized into three key themes: (1) Behaviors—What types of actions can be taken by people, and what evidence is there for adaptive behavior? (2) Antecedents—Which individual and contextual factors can influence people's behaviors? (3) Communications—How can existing insights be better integrated into interventions? Aspects of communication, including the role of message characteristics, messenger, and imagery, are discussed, with examples of messages and narratives that target influential antecedents of adaptive responses to heat risks. The paper makes three important contributions. First, it organizes literature on the antecedents and behavioral responses to heat risk; second, it provides a typology of the range of heat risk behaviors; and, third, it discusses how antecedents can be integrated into communication interventions. The review concludes with a proposed agenda for research, highlighting the need for substantial testing and evaluation of heat risk communication, applying insights from the literature.This article is categorized under:

Perspectives on optimizing local delivery of drugs to peripheral nerves using mathematical models
Authors: Laranjeira Simao , Roberton Victoria H. , Phillips James B. , Shipley Rebecca J. 
Published: January 2023

AbstractDrug therapies for treating peripheral nerve injury repair have shown significant promise in preclinical studies. Despite this, drug treatments are not used routinely clinically to treat patients with peripheral nerve injuries. Drugs delivered systemically are often associated with adverse effects to other tissues and organs; it remains challenging to predict the effective concentration needed at an injured nerve and the appropriate delivery strategy. Local drug delivery approaches are being developed to mitigate this, for example via injections or biomaterial‐mediated release. We propose the integration of mathematical modeling into the development of local drug delivery protocols for peripheral nerve injury repair. Mathematical models have the potential to inform understanding of the different transport mechanisms at play, as well as quantitative predictions around the efficacy of individual local delivery protocols. We discuss existing approaches in the literature, including drawing from other research fields, and present a process for taking forward an integrated mathematical‐experimental approach to accelerate local drug delivery approaches for peripheral nerve injury repair.This article is categorized under:

Serine metabolism contributes to cell survival by regulating extracellular pH and providing an energy source in Saccharomyces cerevisiae
Authors: Kawamukai Arisa , Iwano Ayana , Shibata Momoka , Kishi Yuko , Matsuura Akira 
Published: January 2023

AbstractChanges in extracellular pH affect the homeostasis and survival of unicellular organisms. Supplementation of culture media with amino acids can extend the lifespan of budding yeast, Saccharomyces cerevisiae, by alleviating the decrease in pH. However, the optimal amino acids to use to achieve this end, and the underlying mechanisms involved, remain unclear. Here, we describe the specific role of serine metabolism in the regulation of pH in a medium. The addition of serine to synthetic minimal medium suppressed acidification, and at higher doses increased the pH. CHA1, which encodes a catabolic serine hydratase that degrades serine into ammonium and pyruvate, is essential for serine‐mediated alleviation of acidification. Moreover, serine metabolism supports extra growth after glucose depletion. Therefore, medium supplementation with serine can play a prominent role in the batch culture of budding yeast, controlling extracellular pH through catabolism into ammonium and acting as an energy source after glucose exhaustion.
Novel Homoleptic and Heteroleptic Pt(II) β‐oxodithiocinnamic ester Complexes: Synthesis, Characterization, Interactions with 9‐methylguanine and Antiproliferative Activity

Published: January 2023

AbstractThree new series of homoleptic and heteroleptic platinum(II) β‐oxodithiocinnamic ester complexes, [Pt(L1–L9)2], [Pt(L1–L9)(DMS)Cl] and [Pt(L1–L9)(DMSO)Cl], were synthesized and characterized using elemental analysis, mass spectrometry, and different NMR spectroscopy (1H, 13C{1H} and 195Pt). The β‐oxodithiocinnamic esters coordinate towards the platinum(II) centre as O,S‐bidentate chelating ligands. The structures of HL3, [Pt(L2)2], [Pt(L6)(DMS)Cl] as well as [Pt(L2)(DMSO)Cl] have been confirmed through the X‐ray crystallography, where the platinum(II) complexes exhibit a slightly distorted square planar geometry. In this article, we also investigated the solvolysis of three representative Pt(II) complexes, as well as the interaction with 9‐methylguanine as a DNA model system, by utilizing the LC‐ESI‐MS technique. A selection of the complexes was assessed for their use as anticancer agents, and cytotoxicity assays with these complexes showed modest toxicity on both Cisplatin sensitive and resistant ovarian cancer cell lines. However, the compounds cytotoxicity was not affected by the Cisplatin resistance mechanisms and a specific selection of the ligands may modify the cell line specificity.

Published: January 2023

AbstractEarly Warning Systems (EWSs) are considered one of the main mechanisms for disaster risk reduction (DRR). In this sense, several efforts have been made by the international science and technology community to support the implementation of the Sendai Framework for Disaster Risk Reduction (SFDRR), giving special attention to the seventh global target focused on increasing the availability and access to multi-hazard early warning systems. Considering that landslides are one of the natural and socio-natural hazards that affect society in various parts of the world, the International Consortium on Landslides (ICL) has taken on the task of establishing regional and global network initiatives that promote the establishment of landslides early warnings systems (LEWSs). Although studies have recognised the significance of LEWSs, research has yet to systematically investigate the degree of implementation around the world. Therefore, and building on previous work, this chapter aims to provide an overview concerning enforcement of LEWSs in Upper Middle-Income Countries (UMIs). Based on a systematic literature review, the overall structure of the study takes the form of five sections. An introduction to the significance of LEWSs is provided in the first part. The second section provides an overview of the common architecture of LEWSs. The third part is concerned with the methodology employed for this study. Results of the study are presented in the fourth section and the final part brings together the key findings. Of the total publications that met the specified criteria and were analysed, only 19, that is, 5%, focused on different dimensions of the actual implementation of the LEWS.

Published: January 2023

Abstract
We show how to apply renormalization group algorithms incorporating entanglement filtering methods and a loop optimization to a tensor network which includes Grassmann variables which represent fermions in an underlying lattice field theory. As a numerical test a variety of quantities are calculated for two dimensional Wilson-Majorana fermions and for the two flavor Gross-Neveu model. The improved algorithms show much better accuracy for quantities such as the free energy and the determination of Fisher’s zeros.

Published: January 2023

AbstractSeven plant certified reference materials (NIST SRM1515 Apple Leaves, NIST SRM1547 Peach Leaves, BCR-129 Hay Powder, BCR-670 Aquatic Plant, GBW07603 Bush Twigs and Leaves, GBW10015 Spinach Leaves and NCS ZC73036a Green Tea) were analysed for their mass fractions of 48 elements by inductively coupled plasma tandem-mass spectrometry (ICP-MS/MS): Li, Be, Na, Mg, Al, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Y, Nb, Mo, Ag, Cd, Sb, Te, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Ta, Tl, Pb, Bi, Th, U. Special focus was put on the determination of technology-critical elements (TCEs), to which, e.g. Li, Be, Ga, Ge, Nb, Sb, Ta, Tl, Bi, and the rare-earth elements (REEs, lanthanides and Y) are counted. Closed-vessel microwave digestion was performed using HNO3, H2O2 and HBF4. The average bias for certified values is  − 1% ± 13% (SD). Limits of detection (xL) in the measured solutions lie between 13 fg g−1 (Tb) and 52 ng g−1 (Ca). This article seeks to provide an optimised measurement procedure for the determination of element mass fractions of emerging importance in environmental samples, which are challenging to analyse with more traditional techniques such as single-quad ICP-MS. In addition, it aims to improve the characterisation of commonly used plant reference materials by providing mass fraction data for rarely studied elements.
