An asymptotic decoupling approach for adaptive control with unmeasurable coupled dynamics
Authors: Dogan K. Merve , Yucelen Tansel , Muse Jonathan A. 
Published: October 2020

SummaryWhile adaptive control methods have the capability to suppress the effect of system uncertainties without excessive reliance on dynamical system models, their stability can be adversely affected in the presence of coupled dynamics. Motivated by this standpoint, the contribution of this article is a decoupling approach for model reference adaptive control algorithms. The key feature of the proposed framework is that it guarantees asymptotic convergence between the trajectories of an uncertain dynamical system and a given reference model without relying on any measurements from the coupled dynamics under a tight sufficient stability condition. We also provide a generalization to address the uncertainty in the control effectiveness matrix, where the resulting sufficient stability condition in this case relies on linear matrix inequalities. Finally, numerical examples are provided to illustrate the efficacy of the presented theoretical results.

Published: October 2020

AbstractThe synthesis of serotonin and dopamine with purified enzymes is described. Both pathways start from an amino acid substrate and synthesize the monoamine neurotransmitter in two enzymatic steps. The enzymes human tryptophan hydroxylase isoform 2, Rattus norvegicus tyrosine hydroxylase, Chlamydia pneumoniae Cpn1046, and aromatic amino acid decarboxylase from Drosophila melanogaster are recombinantly expressed, purified, and shown to be functional in vitro. The hydroxylases efficiently convert L‐DOPA (L‐dihydroxy‐phenylalanine) and 5‐HTP (5‐hydroxytryptophan) from L‐tyrosine and L‐tryptophan, respectively. A single aromatic amino acid decarboxylase is capable of converting both hydroxylated intermediates into the final neurotransmitter. The platform described here may facilitate future efforts to generate medically useful artificial cells and nanofactories.

AbstractPrinted random networks of polymer‐wrapped multi‐chiral semiconducting carbon nanotubes (s‐SWCNTs) are an opportunity for mass‐manufacturable, high‐performance large‐area electronics. To meet this goal, a deeper understanding of charge‐transport mechanisms in such mixed networks is crucial. Here, charge transport in field‐effect transistors based on inkjet‐printed s‐SWCNTs networks is investigated, obtaining direct evidence for the phases probed by charge in the accumulated channel, which is critical information to rationalize the different transport properties obtained for different printing conditions. In particular, when the fraction of nanotubes with smaller bandgaps is efficiently interconnected, the sparse network provides efficient charge percolation for band‐like transport, with a charge mobility as high as 20.2 cm2V−1s−1. However, when the charges are forced by a less efficient morphology, to populate also higher bandgap nanotubes and and/or the wrapping polymer, thermally activated transport takes place and mobility drops. As a result, a trade‐off between network density and charge transport properties is identified for device current optimization, in both p‐ and n‐type regimes. These findings shed light on the fundamental aspects related to charge transport in printed s‐SWCNT mixed networks and contribute to devise appropriate strategies for the formulation of inks and processes towards cost‐effective mass production schemes of high‐performance large‐area electronics.
An Adaptable Cryptosystem Enabled by Synergies of Luminogens with Aggregation‐Induced‐Emission Character

Published: October 2020

AbstractThe strong emission in the solid state and the feasibility of introducing stimuli responsiveness make aggregation‐induced‐emission luminogens promising for optical information encryption. Yet, the vast majority of previous reports rely on subtle changes in the molecular conformation or intermolecular interactions, limiting the robustness, multiplicity, capacity, and security of the resulting cryptosystems. Herein, a versatile cryptographic system is presented based on three interconnected and orthogonal covalent transformations concerning a tetraphenylethylene–maleimide conjugate. The cryptosystem is adapted into four configurations with different functionalities by organizing the reactions and molecules in different ways. These variants either balance the accessibility and security of the encrypted information or improve the security and density in data encryption. Significantly, they allow variable decryption from a single encryption and reconstruction of the chemical nature hidden in the fluorescent pattern can only be accessed through given algorithms. These results highlight the importance of multi‐component synergies in advancing information encryption systems, which is enabled by the robustness and diversity stemming from the covalent nature of these transformations.

Published: October 2020

AbstractDeterministic control of the intrinsic polarization state of ferroelectric thin films is essential for device applications. Independently of the well‐established role of electrostatic boundary conditions and epitaxial strain, the importance of growth temperature as a tool to stabilize a target polarization state during thin film growth is shown here. Full control of the intrinsic polarization orientation of PbTiO3 thin films is demonstrated—from monodomain up, through polydomain, to monodomain down as imaged by piezoresponse force microscopy—using changes in the film growth temperature. X‐ray diffraction and scanning transmission electron microscopy reveal a variation of c‐axis related to out‐of‐plane strain gradients. These measurements, supported by Ginzburg–Landau–Devonshire free energy calculations and Rutherford backscattering spectroscopy, point to a defect mediated polarization gradient initiated by a temperature dependent effective built‐in field during growth, allowing polarization control not only under specific growth conditions, but ex‐situ, for subsequent processing and device applications.

Published: October 2020

AbstractBackgroundWithin the mining industrial sector, workers in the mining and oil and gas extraction (OGE) industries have demonstrated disparities in chronic health status compared with the general working population. However, we know much less about miner and OGE worker health once retired. This study separately compares chronic illnesses in retired miners and OGE workers with all other retirees.MethodsNational Health Interview Survey (NHIS) public data were analyzed for the years 2007–2017 to estimate weighted unadjusted and adjusted prevalence of selected health conditions (cancer, cardiovascular disease, high cholesterol, diabetes, hypertension, respiratory conditions, health status, and hearing loss) in retirees. Three retired worker groups (miners, OGE, and other retirees) were defined using the respondents' longest‐held industry and occupation.ResultsHigher prevalence of a number of adverse health conditions was noted in miners and OGE workers when compared with all other retirees. A significantly higher adjusted prevalence of hypertension, hearing loss, functionally limiting lung problems, and fair or poor health was seen in miners over other retirees. Retired OGE workers demonstrated a significantly higher adjusted prevalence of both hearing loss and poor health status.ConclusionsMiners and OGE workers have higher morbidity during their working years, and this study demonstrates that poorer health appears to continue into retirement. These results suggest the need to expand occupational health and safety programs in the mining sector to improve the health of workers into retirement. Future studies that include more robust information on workplace exposures are needed to evaluate the long‐term health of retired workers.
Dynamische kinetische Racematspaltung von Alkoholen mittels enantioselektiver Silylierung ermöglicht durch zwei orthogonale Übergangsmetallkatalysatoren
Authors: Seliger Jan , Oestreich Martin 
Published: October 2020

AbstractEine nichtenzymatische dynamische kinetische Racematspaltung von acyclischen und cyclischen Benzylalkoholen wird vorgestellt. Der Ansatz verbindet rasche übergangsmetallkatalysierte Alkoholracemisierung mit enantioselektiver Cu‐H‐katalysierter Si‐O‐Kupplung von Alkoholen und Hydrosilanen. Die katalytischen Prozesse sind orthogonal und der Racemisierungskatalysator vermittelt keine unerwünschten Hintergrundreaktionen wie die Racemisierung des Silylethers und seine unselektive Bildung. Häufig verwendete Rutheniumhalbsandwichkomplexe sind ungeeignet, aber ein bifunktionaler Rutheniumpincerkomplex erfüllt diesen Zweck vollkommen. Auf diese Weise wird die enantioselektive Silylierung von racemischen Alkoholgemischen in hohen Ausbeuten und mit guten Enantioselektivitäten erreicht.

Published: October 2020

AbstractLithium‐ion batteries with routine carbonate electrolytes cannot exhibit satisfactory fast‐charging performance and lithium plating is widely observed at low temperatures. Herein we demonstrate that a localized high‐concentration electrolyte consisting of 1.5 M lithium bis(fluorosulfonyl)imide in dimethoxyethane with bis(2,2,2‐trifluoroethyl) ether as the diluent, enables fast‐charging of working batteries. A uniform and robust solid electrolyte interphase (SEI) can be achieved on graphite surface through the preferential decomposition of anions. The established SEI can significantly inhibit ether solvent co‐intercalation into graphite and achieve highly reversible Li+ intercalation/de‐intercalation. The graphite | Li cells exhibit fast‐charging potential (340 mAh g−1 at 0.2 C and 220 mAh g−1 at 4 C), excellent cycling stability (ca. 85.5 % initial capacity retention for 200 cycles at 4 C), and impressive low‐temperature performance.

Published: October 2020

AbstractA highly active graphdiyne heterojunction with highly efficient photocatalysis is designed and fabricated. This catalyst demonstrates transformative properties on photocatalysis for ammonia synthesis. Such excellent properties are reigned from graphdiyne incorporating Fe site‐specific magnetite resulting in a valence state transition within the catalyst. Our results show the strong advantages of graphdiyne in effectively regulating magnetite activity and coordination environments and also indicate that magnetite can selectively form two different valence tetrahedral coordination Fe and octahedral coordination Fe. The catalysts show remarkable catalytic performance for ammonia synthesis by photocatalysis, indicating transformative photocatalytic activity with an ammonia yield (Y
) of unprecedented level of 1762.35±153.71 μmol h−1 gcat.−1 (the highest Y
could reach up to 1916.06 μmol h−1 gcat.−1). This work makes full use of the structural and property features of graphdiyne and opens up a new direction for photocatalysis in the field of catalysis.
Adsorption Site Selective Occupation Strategy within a Metal–Organic Framework for Highly Efficient Sieving Acetylene from Carbon Dioxide

Published: October 2020

AbstractThe separation of acetylene and carbon dioxide is an essential but challenging process owing to the similar molecular sizes and physical properties of the two gas molecules. Notably, these molecules usually exhibit different orientations in the pore channel. We report an adsorption site selective occupation strategy by taking advantage of differences in orientation to sieve the C2H2 from CO2 in a judiciously designed amine‐functionalized metal–organic framework, termed CPL‐1‐NH2. In this material, the incorporation of amino groups not only occupies the adsorption sites of CO2 molecules and shields the interaction of uncoordinated oxygen atom and CO2 molecules resulting in a negligible adsorption amount and a decrease in enthalpy of adsorption but also strengthened the binding affinity toward C2H2 molecules. This material thus shows an extremely high amount of C2H2 at low pressure and a remarkably high C2H2/CO2 IAST selectivity (119) at 1 bar and 298 K.
Flame front propagation and sinter strength properties of permeable sintering bed prepared via enhanced granulation with hydrated lime
Authors: Zhou Mingxi , Zhou Hao 
Published: October 2020

AbstractThis paper is focused on investigating the influences of enhanced granulation with hydrated lime on the propagation of flame front and strength properties of the produced sinter in iron ore sintering. Pilot‐scale sinter pot experiments were performed at three hydrated lime levels, and the porous structures of sinter were reconstructed by high resolution X‐ray tomography. When hydrated lime increased from 0% to 2%, more permeable green bed with enlarged granule mean size and narrowed granule size distribution could be obtained, and sinter productivity increased from 37.3 to 40.7 t/m2/d while tumbler index of sinter decreased from 62.7% to 55.0%. Both the bed temperature and pressure profiles verified that hydrated lime addition fasten sintering by reduction of heat accumulation and acceleration of flame front speed in sintering bed. The three‐dimensional stress analysis based on the actual microstructures showed that more irregular sinter particles with higher porosity are obtained with higher hydrated lime due to the insufficient melt formation and coalescence during sintering. Sinter with 2% hydrated lime was much more compliant under the fixed compression, exhibiting larger potential to be deformed in locations including bridges with the small cross sections and notches with the small fillet radius.

Abstract

To our knowledge, this is the first inclusive assessment of the status of Sparidae fisheries in the territorial waters of Kuwait, integrating information on catch trends, consumer preferences, recreational fishing behaviour, and molecular based identification of fish species by DNA barcoding
Fisheries landing data were obtained from the official fisheries bulletin released by the Kuwait Central Statistical Bureau. Surveys were conducted to assess consumer preferences on seabream species, landed seabream species, and the behaviour of recreational anglers towards seabream species. DNA barcodes were generated to authenticate commercial seabream using the mitochondrial cytochrome c oxidase subunit I (COXI) gene and then compared with GenBank sequence entries; these sequences were then used to construct a neighbour‐joining (NJ) phylogenetic tree.
Yellowfin seabream Acanthopagrus latus was the prime and most favoured commercial seabream species (45%), followed by Sparidentex hasta, which was the top‐rated secondary, unassessed seabream species. Approximately 54% of households conduct recreational fishing more than twice a month, and most (77%) primarily target S. hasta and Ac. latus. Consumer demand for secondary seabreams, which were not assessed and are listed in the bulletin under the category ‘others’, was evident.
The NJ phylogenetic tree revealed that Arabian Gulf seabreams, including those of Kuwait, are genetically different from their counterparts inhabiting neighbouring waters.
The data presented here highlight the urgency to modify the existing fisheries list using accurate identification tools, such as DNA barcoding, for the sustainable and conservation‐oriented management of local fisheries, which are in decline.

Published: October 2020

Angelman syndrome (AS), a genetic disorder that primarily affects the nervous system, is characterized by delayed development, intellectual disability, severe speech impairment, and problems with movement and balance (ataxia). Most affected children also have recurrent seizures (epilepsy). No existing therapies are capable of comprehensively treating the deficits in AS; hence, there is an urgent need to identify new treatments. Here we show that insulin‐like growth factor 2 (IGF‐2) and mannose‐6‐phosphate (M6P), ligands of two independent binding sites of the cation‐independent M6P/IGF‐2 receptor (CIM6P/IGF‐2R), reverse most major deficits of AS modeled in mice. Subcutaneous injection of IGF‐2 or M6P in mice modeling AS restored cognitive impairments as assessed by measurements of contextual and recognition memories, motor deficits assessed by rotarod and hindlimb clasping, and working memory/flexibility measured by Y‐maze. IGF‐2 also corrected deficits in marble burying and significantly attenuated acoustically induced seizures. An observational battery of tests confirmed that neither ligand changed basic functions including physical characteristics, general behavioral responses, and sensory reflexes, indicating that they are relatively safe. Our data provide strong preclinical evidence that targeting CIM6P/IGF‐2R is a promising approach for developing novel therapeutics for AS.Lay SummaryThere is no effective treatment for the neurodevelopmental disorder Angelman syndrome (AS). Using a validated AS mouse model, the Ube3am−/p+, in this study we show that systemic administration of ligands of the cation independent mannose‐6‐phosphate receptor, also known as insulin‐like growth factor 2 receptor (CIM6P/IGF‐2R) reverses cognitive impairment, motor deficits, as well as seizures associated with AS. Thus, ligands that activate the CIM6P/IGF‐2R may represent novel, potential therapeutic targets for AS.
Health risks from protozoa in potable reuse: Implications of Florida's data set
Authors: MacNevin David , Zornes Greta 
Published: October 2020

AbstractOver the past two decades, 292 Florida water reclamation facilities (WRFs) have collected reclaimed water protozoa data. This paperexamines the data set, which includes more than 1,800 observations of each protozoan, including Cryptosporidium and Giardia. This study considers the occurrence of protozoa across WRFs and the potential implications for potable reuse. Quantitative microbial risk assessment was conducted for reclaimed waters from 20 WRFs to assess the necessary log reduction credit to treat water from each facility for Cryptosporidium and Giardia. These results are compared with advanced treatment trains based on either reverse osmosis or ozone with biologically active filtration.
An Excel VBA‐based educational module for bed roughness predictors
Authors: Niazkar Majid 
Published: October 2020

AbstractEstimation of flow resistance coefficients plays an inevitable role in open‐channel flows in hydraulic modeling and water resources engineering. Despite many equations and methods recommended for estimating roughness coefficients, only two standard resistance equations (original Manning's and Keulegan's equations) have been widely taught and utilized in practice. There can be various reasons for not using new bed roughness predictors (BRPs), one of which is the absence of teaching BRPs. A rigorous analysis of available BRPs for estimating grain and form roughness coefficients delineates that most of them are comprised of a scheme rather than a single equation. Also, each BRP is tailored to solve a distinct type of problem; however, a proper definition of a problem statement helps shedding light on this application. This study presents an Excel VBA‐based educational estimator to address the gap. For this purpose, the problem statement is first revisited to accomplish a better understanding in light of proper problem classification. On the basis of different groups of input and output data, each BRP is implemented into an Excel spreadsheet and VBA codes are presented for BRPs incorporating both grain and form roughness. This computer application can help students in open‐channel engineering courses not only to become familiar with modified BRPs but also to acknowledge the merit of the Excel spreadsheet for estimating flow resistance coefficients. Finally, as the VBA codes are presented in detail, they can be modified by users in accordance with their priorities for both educational and practical purposes.

AbstractIt is unclear to what extent patients with pancreatic cancer have cachexia and had a dietetic consult for nutritional support. The aim was to assess the prevalence of cachexia, dietitian consultation, and overall survival in these patients. This prospective multicenter cohort study included patients with pancreatic cancer, who participated in the Dutch Pancreatic Cancer Project and completed patient reported outcome measures (2015–2018). Additional data were obtained from the Netherlands Cancer Registry. Cachexia was defined as self‐reported >5% body weight loss, or >2% in patients with a BMI <20 kg/m2over the past half year. The Kaplan–Meier method was used to analyze overall survival. In total, 202 patients were included from 18 centers. Cachexia was present in 144 patients (71%) and 81 of those patients (56%) had dietetic consultation. Cachexia was present in 63% of 94 patients who underwent surgery, 77% of 70 patients who received palliative chemotherapy and 82% of 38 patients who had best supportive care. Dietitian consultation was reported in 53%, 52%, and 71%, respectively. Median overall survival did not differ between patients with and without cachexia, but decreased in those with severe weight loss (12 months (IQR 7–20) vs. 16 months (IQR 8–31), p = 0.02), as compared to those with <10% weight loss during the past half year. Two‐thirds of patients with pancreatic cancer present with cachexia of which nearly half had no dietetic consultation. Survival was comparable in patients with and without cachexia, but decreased in patients with more severe weight loss.
