A Multi‐Criteria Study of Optimal Working Fluids for High Temperature Heat Pumps
Authors: Mairhofer Jonas , Stavrou Marina 
Published: December 2022

AbstractA bi‐objective optimization with respect to coefficient of performance (COP) and volumetric heating capacity (VHC) is performed for a high temperature heat pump. For fixed temperature levels of the heat source and sink, the values for temperature in the evaporator and condenser as well as the degree of vapor super‐heating and condensate sub‐cooling are optimized. Constraints are placed on the minimal pressure in the evaporator, the maximal pressure in the condenser and the compressor discharge temperature. Results are presented for a one‐stage and a two‐stage heat pump cycle. Cyclobutane and several butene isomers are identified as working fluids with a good compromise between COP and VHC from a CoMT‐CAMD approach based on PC‐SAFT and a realistic model for the ideal gas heat capacity.

Published: December 2022

AbstractHydrogen energy production through photoelectrochemical (PEC) water splitting has great potential in the field of renewable energy. This study focuses on the hydration enthalpy difference of cations (Li+, Na+, and K+) in an aqueous solution for the chemical self‐oxidation process without an external applied bias. The thickness of the cation/H2O double layer is controlled. The starting materials are low‐cost copper foil and the synthesis uses alkali cation‐engineered chemical self‐oxidation. Li+ ions are strongly attracted to water molecules. This forms a sufficient OH− layer on the Cu foil surface. By accelerating the oxidation reaction, a large surface area of Cu(OH)x nanowires (NWs) with high purity and a uniform shape are obtained. This optimal p‐type Cu2O NWs photocathode is CuO‐free, has the highest conductivity, and is fabricated through phase transition using precise vacuum annealing. The other alkali cations produce the Cu2O/CuO mixed or CuO phases that degrade the PEC performances with severe corrosive reactions. The Cu/Li : Cu2O/AZO/TiO2/Pt photocathode has a 50 h stability with a photocurrent density of 8.4 mA cm−2 at 0 VRHE. The fabricated photoelectrode did not structurally collapse after stability measurements during this period. The captured hydrogen production was in agreement with the calculated faradaic efficiency.
Joint power and hopping rate adaption against follower jammer based on deep reinforcement learning

Published: December 2022

AbstractAs an effective anti‐jamming approach, frequency‐hopping (FH) technology has been widely applied to tactical communication system, providing reliable communication guarantee and improving resilience against conventional interference under strong confrontation environment. Key challenges for tactical wireless communication network face are the smart follower jammer with responsive spectrum reconnaissance and intelligent decision‐making capabilities. In response, this article investigates a deep reinforcement learning based anti‐jamming scheme, with the aim of maximizing the system throughput. The interactions between a radio transmitter and a smart follower jammer are formulated as a hierarchical anti‐jamming dynamic game model, in which the radio terminal decides transmission power and hopping rate according to the state feedback information, and the jammer chooses spectrum scanning rate accordingly to minimizing the rewards of the FH communication system. We prove that there is a Nash equilibrium (NE) strategy for static and dynamic environment in the game. A double deep Q‐network with prioritized experience reply (PDDQN) based anti‐jamming scheme is proposed to approximating the optimal power control and hopping strategy without being aware of the environment and jamming parameters. Finally, simulation results demonstrate that the proposed algorithm efficiently provide better throughput and jamming resistance.
The intermingled meanings ofPhoneMe: Exploring transmodal, place‐based poetry in an online social network
Authors: Horst Rachel , James Kedrick , Morales Esteban , Takeda Yuya 
Published: December 2022

AbstractThis research paper explores how preservice teachers engaged with the transmodal place‐based poetry on PhoneMe, an educational social media platform for sharing poetry and vocal performances about place. This work is situated in literature on digital place‐based education and theoretical scholarship exploring transmodality and the shifting entanglement of meanings and modes. In this paper, we share findings from a research survey conducted with teacher candidates in a core teacher education literacy course that had transitioned online due to the COVID‐19 pandemic. We discuss how participants engaged with the transmodal poetry in the survey and how their perceived poetic meaning and poetic connections changed with each additional modality. We share the pedagogical implications of our findings as well as ideas gleaned from the data for integrating the PhoneMe platform and pedagogy in secondary school classrooms. In the discussion, we explore how engagement with transmodal place‐based digital poetry can be a unique way to draw together place‐based education, digital literacies, social media literacies, and poetry pedagogy in a way that is visceral, relational, and highly relevant to contemporary lives and classrooms both on and offline.

Authors: Brodney Marian D. , Bakken Gregory , Butler Christopher R. , Klug‐McLeod Jacquelyn , Owen Robert , Sng Shao‐Tien 
Published: December 2022

AbstractAn integrated design environment (IDE) has been developed that allows the capture of design ideas, virtual compounds, and design hypotheses for medicinal chemistry projects. Specific consideration for rational molecular design, including design strategy and tactics, as well as comparator reference compounds have been incorporated to more easily convey the proposed design idea. A hierarchical tree architecture and customizable layouts allow for facile browsing across multiple programs and rapid examination of both ongoing and newly designed virtual compounds enabling centralized team discussions to ensure the most efficient prosecution of a queue of these target compounds. Additionally, a “whiteboard” module was incorporated for the rapid evaluation of virtual compounds against a suite of computational models enabling real‐time design and triage. Finally, aggregation of cross‐project design data enables broader analyses that can indicate portfolio‐wide design challenges.

Published: December 2022

AbstractThe endophytic fungus Neurospora dictyophora 3ZF‐02 with a special aroma was isolated from the arils of Torreya grandis. Analysis of volatile organic compounds was done by gas chromatography–mass spectrometry. A total of 46 compounds were identified in the volatile organic compounds by 3ZF‐02. In the growth phase, esters, acids, along with some alcohols and ketones were the main components. During the recession period, a large amount of benzene and naphthalene compounds appeared, accompanied by the production of amines. Oleic acid, methyl abietate, terpinen‐4‐ol were also found. They were the same ingredients in essential oil of Torreya. The antioxidant activity and antifungal activity of all extracts were also evaluated. When cultured for 10 days, it exhibited the most significant antioxidant activity with IC50 of 1.44 and 0.95 g/L against diphenyl picryl hydrazinyl and hydroxyl radicals, respectively. In addition, the extracts cultured for 10 days exhibited the most significant antifungal activity against Candida albicans with minimum inhibitory concentration 1.56 mg/ml.

AbstractIn lakes, seasonal phytoplankton blooms and allochthonous plant debris intensify particulate organic carbon fluxes to the lakebed. Microbes associated with these particles likely vary with organic substrate lability and redox conditions. To explore microbial compositional responses to these variables, we analyzed particle‐associated and free‐living assemblages in the permanently redox‐stratified Fayetteville Green Lake using 16 S rRNA amplicon sequencing during the peak and end of cyanobacterial and photoautotrophic sulfur bacterial blooms. Assemblage compositions were strongly influenced by redox conditions and particle association. Assemblage compositions varied seasonally above the lower oxycline boundary (summer—generalist heterotrophs; autumn—iron reducers and specialist heterotrophs), but not in the anoxic region below. Particle‐associated assemblages were less diverse than free‐living assemblages and were dominated by heterotrophs that putatively metabolize complex organic substrates, purple sulfur bacteria, sulfur‐cycling Desulfocapsa, and eukaryotic algae. The least diverse particle‐associated assemblages occurred near the lower oxycline boundary, where microbial activities and abundances were highest, and anoxygenic photoautotrophs were enriched. The low‐diversity particle‐associated heterotrophs likely remineralize complex organic substrates, releasing simpler organic substrates to free‐living assemblages during transit, thereby influencing surrounding microbial diversity and function. Our results challenge the paradigm that phytoplankton from the shallow photic zone are the primary contributor to the vertical flux. We suggest that photoautotrophic prokaryotes from the deep photic zone contribute significantly to deep‐water carbon in this environment, and possibly in other oxygen‐deficient waters with sulfidic photic zones. Furthermore, results suggest that seasonally variable terrestrial carbon and metal inputs also influence microbial diversity and function in similar systems.

Published: December 2022

AbstractThe development of polymer acceptors is of crucial importance for all‐polymer solar cells (all‐PSCs). However, the state‐of‐the‐art polymer acceptors are typically based on Y‐series small molecule acceptors. Their synthetic complexity and high synthesis cost remain a severe challenge for future practical application of organic photovoltaics. Herein, a novel non‐fused polymer acceptor named PDO is synthesized. The all‐PSC achieves a best power conversion efficiency of 9.68% in the layer‐by‐layer (LBL) processed device, which is much better than that (8.14%) of the conventional bulk‐heterojunction device. Comprehensive analysis on the electrical and morphological characterizations reveal that the improved device performance in the LBL‐processed device is originated from efficient exciton extraction and charge transport, suppresses charge recombination, improves molecular ordering, and optimizes active layer morphology. These results validate that the fabrication of all‐PSCs with non‐fused polymerized small molecule acceptors is a promising strategy to develop low‐cost and high‐performance all‐PSCs.
Transcatheter pulmonary valve replacement in congenital heart diseases
Authors: Chau Adolphus Kai‐Tung 
Published: December 2022

ABSTRACTSurgical repair of a variety of congenital heart diseases involves repair of the right ventricular outflow tract (RVOT) with valved or non‐valved conduit to connect the right ventricle (RV) to the pulmonary artery (PA) or just patch enlargement of the native RVOT. With time, this RV‐PA conduit will degenerate with deterioration of function, either causing pulmonary stenosis or pulmonary regurgitation. This RVOT dysfunction may result in RV dilation, RV dysfunction, and eventual RV failure and arrhythmias. Multiple surgical pulmonary valve replacement (PVR) is often required throughout the patient's lifetime. Patients are subjected to increased risks with each additional cardiac operation. Transcatheter PVR (TPVR) has been developed over the past two decades as a valuable non‐surgical alternative to restore the RVOT and RV function, and hence reduce patients’ lifetime risks related to surgery. This article will discuss the long‐term results of TPVR which are demonstrated to be comparable to surgical results and the latest development of large pulmonary valves which will allow TPVR to be performed on native or larger RVOT.
A density‐based time‐series data analysis methodology for shadow detection in rooftop photovoltaic systems
Authors: Tsafarakis Odysseas , van Sark Wilfried G.J.H.M. 
Published: December 2022

AbstractThe majority of photovoltaic (PV) systems in the Netherlands are small scale, installed on rooftops, where the lack of onsite global tilted irradiance (GTI) measurements and the frequent presence of shadow due to objects in the close vicinity oppose challenge in their monitoring process. In this study, a new algorithmic tool is introduced that creates a reference data‐set through the combination of data‐sets of the unshaded PV systems in the surrounding area. It subsequently compares the created reference data‐set with the one of the PV system of interest, detects any energy loss and clusters the distinctive loss due to shadow, created by the surrounding objects. The new algorithm is applied successfully to a number of different cases of shaded PV systems. Finally, suggestions on the unsupervised use of the algorithm by any monitoring platform are discussed, along with its limitations algorithm and suggestions for further research.
Generalized likelihood ratio based risk‐adjusted control chart for zero‐inflated Poisson process
Authors: Lai Xin , Lian Xin , Liu Liu , Wang Jiayin , Liu Yuqian , Chong Ka Chun 
Published: December 2022

AbstractNowadays, statistical process control has been widely used to monitor processes in various fields. To monitor processes with a large number of zero observations by control charts, the zero‐inflated Poisson (ZIP) model has been adopted. Due to the heterogeneity of each sample in the process, several factors have been taken into account to predict values of two parameters in the ZIP model by risk adjustment. Instead of considering two parameters to be constant directly, risk‐adjusted ZIP control charts can provide more reasonable monitoring results than traditional ones. However, existing methods ignored the interaction between parameters in the ZIP model, which leads to some risk‐adjusted control charts unable to accurately estimate parameters to provide effective monitoring results. To address this problem, this paper presents a generalize likelihood ratio (GLR) based control chart to better monitor the risk‐adjusted ZIP process with EWMA scheme, which can detect the random shift in both parameters efficiently. In the simulation study, the proposed control chart is compared with another two existing control charts and shows superior performance on detecting various types of shifts in parameters. Finally, the proposed control chart is applied to the Hong Kong influenza datasets and the flight delay datasets to illustrate its effectiveness and utility.

AbstractAutoantibodies (AABs) play a critical role in the pathogenesis of autoimmune diseases (AIDs) and serve as a diagnostic and prognostic tool in assessing these complex disorders. Viral infections have long been recognized as a principal environmental factor affecting the production of AABs and the development of autoimmunity. COVID‐19 has primarily been considered a hyperinflammatory syndrome triggered by a cytokine storm. In the following, the role of maladaptive B cell response and AABs became more apparent in COVID‐19 pathogenesis. The current review will primarily focus on the role of extrafollicular B cell response, Toll‐like receptor‐7 (TLR‐7) activation, and neutrophil extracellular traps (NETs) formation in the development of AABs following SARS‐CoV‐2 infection. In the following, this review will clarify how these AABs dysregulate immune response to SARS‐CoV‐2 by disrupting cytokine function and triggering neutrophil hyper‐reactivity. Finally, the pathologic effects of these AABs will be further described in COVID‐19 associate clinical manifestations, including venous and arterial thrombosis, a multisystem inflammatory syndrome in children (MIS‐C), acute respiratory distress syndrome (ARDS), and recently described post‐acute sequelae of COVID‐19 (PASC) or long‐COVID.

AbstractTandem one‐pot five‐component reaction involving saccharin, propargyl bromide, aldehyde, hydroxylamine hydrochloride, and non‐conjugated primary amine has been explored for a rapid and an efficient synthesis of isoxazole‐secondary sulfonamides. This novel multicomponent reaction involves one pot N‐propargylation of saccharin, oximation, and 1,3‐dipolar cycloaddition, followed by an intermolecular ring‐opening reaction by N‐nucleophilic amine. This transformation is catalyzed by CaCl2/K2CO3 and activated under ultrasonic cavitation. The CaCl2 salt is reported for the first time as a new precatalyst and a chlorine source. We showed that ultrasound, using sonotrode, significantly improved the reaction compared to ultrasonic bath and magnetic stirring. The isoxazole‐secondary sulfonamides 6 a–r were obtained in good to excellent yields (75–96 %) and withing shorter reaction times (13–17 min). All the synthesized compounds were fully characterized by IR, MS‐ESI, 1H NMR, 13C NMR spectroscopy, X‐ray crystallography and HPLC analysis.

AbstractThis study describes the synthesis of Pd0 nanoparticles supported in hydrogel networks (SPVI@Pd) and their catalytic activity for the borane‐morpholine complex (MB) hydrolysis reaction. In this respect, while our study is one of the limited number of studies reported for the catalytic hydrolysis of MB, it is the first study in which Pd0 nanoparticles supported in hydrogel networks were used in the catalytic hydrolysis of MB. The synthesized Pd0 nanoparticles were characterized using structural and morphological characterization techniques and as a result of these analyses, the sizes of Pd0 nanoparticles were determined average as 7.01±1.90 nm. The Ea value and the turnover frequency (TOF) value at 303 K for the SPVI@Pd3.0 catalyzed MB hydrolysis reaction were determined as 49.46 kJ/mol and 187.74 molH2 ⋅ molPd−1 ⋅ h−1. It was also observed that the SPVI@Pd3.0 catalyst had good catalytic activity even after eight cycles.

AbstractOxygen evolution reaction (OER) plays key roles in the energy efficiency of electro‐catalytic systems. However, the sluggish kinetics and accumulated gas slugs under the industrial operation condition limit the application of OER. Herein, Mn, Fe co‐doped nickel hydroxide with highly dense nano‐sheets array is obtained through a simple and mild two‐step etching strategy, which exhibits a remarkable OER performance. Doping Mn and Fe can modulate the electronic structure and redox behavior of active site, leading to an excellent intrinsic activity toward OER. Moreover, highly dense nanoparticle‐nanosheet array structure is conducive to provide more active sites and inhibit the accumulation of gas slugs under industrial current density. Thus, the obtained catalyst provides an impressing current density of 1.8 A cm−2at a small overpotential of 370 mV and sustains the performance more than 100 h.
Photo‐Responded Antibacterial Therapy of Reinfection in Percutaneous Implants by Nanostructured Bio‐Heterojunction

Published: December 2022

AbstractPercutaneous implants may experience infection for several times during their servicing periods. They need antibacterial activity and durability to reduce recurrent infection and cytocompatibility to reconstruct biosealing. A novel photoresponse bio‐heterojunction (PCT) is developed herein. It consists of TiO2 nanotubes loaded with CuS nanoparticles and wrapped with polydopamine (PDA) layer. In PCT, a built‐in electric field directing from TiO2 to CuS and then to PDA is formed, and with near‐infrared (NIR) irradiation, it drives photoexcited electrons to transfer in opposite direction, resulting in the separation of electron–hole pairs and formation of reactive oxygen species (ROS). Simultaneously, PCT shows photothermal effect due to nonradiative relaxation of photoexcited electrons and thermal vibration of lattices. The synergic effect of photogenerated ROS and hyperthermia increases bacterial membrane permeability and leakage of cellular components, endowing PCT with outstanding antibacterial performance. More importantly, PCT has good antibacterial durability and cytocompatibility due to the inhibited leaching of CuS by PDA layer. In reinfected models, with NIR irradiation, PCT sterilizes bacteria, reduces inflammatory response and enhances re‐integration of soft tissue efficiently. This work provides an outstanding bio‐heterojunction for percutaneous implants in treating reinfection by NIR irradiation and rebuilding biosealing.
