AbstractAfterglow is superior to other optical modalities for biomedical applications in that it can exclude the autofluorescence background. Nevertheless, afterglow has rarely been applied to the high‐contrast “off‐to‐on” activatable sensing scheme because the complicated afterglow systems hamper the additional inclusion of sensory functions while preserving the afterglow luminescence. Herein, a simple formulation of a multifunctional components‐incorporated afterglow nanosensor (MANS) is developed for the superoxide‐responsive activatable afterglow imaging of cisplatin‐induced kidney injury. A multifunctional iridium complex (Ir‐OTf) is designed to recover its photoactivities (phosphorescence and the ability of singlet oxygen‐generating afterglow initiator) upon exposure to superoxide. To construct the nanoscopic afterglow detection system (MANS), Ir‐OTf is incorporated with another multifunctional molecule (rubrene) in the polymeric micellar nanoparticle, where rubrene also plays dual roles as an afterglow substrate and a luminophore. The multiple functions covered by Ir‐OTf and rubrene renders the composition of MANS quite simple, which exhibits superoxide‐responsive “off‐to‐on” activatable afterglow luminescence for periods longer than 11 min after the termination of pre‐excitation. Finally, MANS is successfully applied to the molecular imaging of cisplatin‐induced kidney injury with activatable afterglow signals responsive to pathologically overproduced superoxide in a mouse model without autofluorescence background.

Published: March 2022

AbstractThe evolution of persistent memory (PM) has significantly affected the design of today's indexing structures. Hashing‐based structures are widely used in storage systems to achieve fast query responses. Recently, several concurrent and failure‐atomic hashing schemes for PM have been proposed to improve the scalability. However, these works still suffer from limited scalability, especially under write‐intensive workloads or at a high number of threads. Our empirical study concludes three issues harm the scalability of PM hashing schemes: the NUMA effects, the resizing operations, and the inter‐thread interference overhead in PM. Based on the above scalability issues, we present SPHT, a scalable and persistent hashing scheme for hybrid DRAM‐PM memory. To eliminate the NUMA effects, SPHT maintains a hash subtable for every NUMA node and stores the key‐value items in the designated nodes. By doing so, all operations can be executed in the local memory without cross‐node communication. The hash subtable consists of two components: the search layer in DRAM for fast accesses and the data layer in PM for efficient persistence. The data layer is organized in a log‐structured way and its log chunks own separate PM space, thus avoiding the resizing operations in PM. Meanwhile, the compacted log structure also supports batching multiple small items, which effectively reduces the persistence overhead. Furthermore, to maximize concurrency, we assign threads to different partitions in the data layer to reduce the inter‐thread interference overhead. On Intel Optane DCPMM, our evaluations show that SPHT scales well and achieves up to 2.7 higher performance than state‐of‐the‐art PM hashing schemes under YCSB workloads.

Published: March 2022

AbstractElectrochemical C−H functionalization is a rapidly growing area of interest in organic synthesis. To achieve maximum atom economy, the flow electrolysis process is more sustainable. This allows shorter reaction times, safer working environments, and better selectivities. Using this technology, the problem of overoxidation can be reduced and less emergence of side products or no side products are possible. Flow electro‐reactors provide high surface‐to‐volume ratios and contain electrodes that are closely spaced where the diffusion layers overlap to give the desired product, electrochemical processes can now be managed without the need for a deliberately added supporting electrolyte. Considering the importance of flow electrochemical C−H functionalization, a comprehensive review is presented. Herein, we summarize flow electrolysis for the construction of C−C and C−X (X=O, N, S, and I) bonds formation. Also, benzylic oxidation and access to biologically active molecules are discussed.

Published: March 2022

Impedance cardiography (ICG) and peripheral bioimpedance may be useful for monitoring several cardiovascular parameters such as cardiac output, stroke volume, blood pressure and heart rate. It is a noninvasive and low‐cost method and could be useful for diagnosis and treatment in different clinical situations. This study involved 100 volunteers and their age ranging from 18 to 26 years. The acquired bioimpedance signal was pre‐processed and used to estimate the heart rate. Thus, heart rates of each subject were calculated and then compared with actual measurement from FUZZY model MP3 digital blood pressure monitor. The results showed high precision with a 1.38 mean error a high sensitivity of 99.81% and a positive predictivity value of 99.63%, respectively. Compared with six other methods selected from the literature review and which are initially dedicated to ECG signals, the proposed method has been found to be more efficient and more precise with an error in determining the percentile HR = 1.78%. © 2022 Institute of Electrical Engineers of Japan.

Published: March 2022

AbstractThis study focuses on the settling profile and chemical characteristics of latex aerobic granules cultivated from rubber industrial wastewater. Latex‐based aerobic granular sludge (AGS) was cultivated using sequencing batch reactor (SBR) in supplemented with synthetic wastewater (SW) as nutrients feeding for biogranulation process. The bioreactor was operated for 24 h with eight series of intermittent 3 h SBR cycles continuously. The SBR configuration comprises of five operation phases from SW feeding, aeration, settling, and effluent decanting to idle. Latex granules exhibit a loose and irregular structure dominated by coccal‐shaped bacteria with an average size of 4.0–5.0 mm and a settling velocity of 0.35–0.53 m h–1. The elemental analysis using X‐ray fluorescence (XRF) showed that the latex granules contained various elements while X‐Ray diffraction (XRD) analysis suggested the presence of zincowoodwardite, berlinite, rutile, and quartz. Fourier transform infrared spectroscopy (FTIR) analysis revealed the presence of aliphatic hydrocarbons, alkene, alkyne, and tertiary amine.

ABSTRACTObjectiveTo describe the clinical and ultrasound features of ovarian mature cystic teratomas (MCTs).MethodsThis was a retrospective study. From the International Ovarian Tumor Analysis (IOTA) database, we identified patients with a histologically confirmed diagnosis of MCT who had undergone transvaginal ultrasound examination between 1999 and 2016 (IOTA phases 1, 2, 3 and 5) in one of five centers. Ultrasound was performed by an experienced examiner who used the standardized IOTA examination technique and terminology. In addition to extracting data from the IOTA database, available two‐dimensional grayscale and color or power Doppler images were reviewed retrospectively to identify typical ultrasound features of MCT described previously and detect possible new features using pattern recognition. All images were reviewed by two independent examiners and further discussed with two ultrasound experts to reach consensus.ResultsIncluded in the study were 454 patients with histologically confirmed MCT. Median age was 33 (range, 8–90)  years and 66 (14.5%) patients were postmenopausal. Most MCTs were described by the original ultrasound examiner as unilocular (262/454 (57.7%)) or multilocular (70/454 (15.4%)) cysts with mixed echogenicity of cystic fluid (368/454 (81.1%)), acoustic shadowing (328/454 (72.2%)) and no or little vascularization on color Doppler (color score 1, 240/454 (52.9%); color score 2, 123/454 (27.1%)). The median largest lesion diameter was 66 (range, 15–310)  mm. A correct preoperative diagnosis of MCT was suggested by the original ultrasound examiner in 372/454 (81.9%) cases. On retrospective review of ultrasound images of 334 MCTs that had quality sufficient for assessment, ‘dots and/or lines’ and/or ‘echogenic white ball’ (typical features according to the literature) were present in 271/334 (81.1%) masses. We identified four new ultrasound features characteristic of MCT: ‘cotton wool tufts’, ‘mushroom cap sign’, ‘completely hyperechogenic lesion’ and ‘starry sky sign’. At least one classical or novel ultrasound feature was present in 315/334 (94.3%) MCTs. Twenty‐nine (8.7%) MCTs manifested vascularized solid tissue, of which seven exhibited no typical features.ConclusionWe provide a comprehensive overview of conventional and newly described ultrasound features of MCTs. Only a small proportion of MCTs did not manifest any of the typical features. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Published: March 2022

AbstractA 5‐year‐old, male, entire labrador was treated for grade III tetanus, developing aspiration pneumonia and undergoing mechanical ventilation. However, 5 days after weaning from mechanical ventilation, the dog developed a new pyrexia. Investigations documented circulating intracellular bacteria, a bacterial peritonitis and a large right jugular thrombus. Blood, peritoneal and urinary cultures yielded a multidrug‐resistant Escherichia coli. The jugular catheter had been in place for 10 days, and the dog had received parenteral nutrition. The pyrexia resolved immediately after catheter removal and there was no echocardiographic evidence of endocarditis. No abdominal source of infection was identified by computed tomography and the septic peritonitis was managed conservatively, including percutaneous placement of an indwelling peritoneal drain for drainage and lavage. The dog was escalated to intravenous gentamicin antibiosis with ongoing supportive care, and discharged with cefovecin, making a full recovery after 20 days in the intensive care unit.

Published: March 2022

AbstractA spayed Boston terrier was referred for nutritional advice after failing to respond to long‐term medical and dietary treatment for chronic pancreatitis. Based on clinical appearance, consecutive bloodwork and ultrasound examination, the concomitant occurrence of inflammatory bowel disease was likely. An exclusion diet (novel protein approach) and a stepwise balancing schedule were formulated to address combined nutritional recommendations, as well as the possibility for hypersensitivity to play a role. After initiation of the exclusion diet, the patient relapsed twice. Once due to non‐compliance of the owner, once due to reaction to an added supplement. After correction, no major relapses were noted for at least 1 year. To the authors’ knowledge, this report is the first to describe the successful supportive care of chronic pancreatitis and concurrent inflammatory bowel disease by prescribing a homemade diet.
Time‐dependent density matrix renormalization group method for quantum dynamics in complex systems
Authors: Ren Jiajun , Li Weitang , Jiang Tong , Wang Yuanheng , Shuai Zhigang 
Published: March 2022

AbstractThe simulations of spectroscopy and quantum dynamics are of vital importance to the understanding of the electronic processes in complex systems, including the radiative/radiationless electronic relaxation relevant for optical emission, charge/energy transfer in molecular aggregates related to carrier mobility in organic materials, as well as photovoltaic and thermoelectric conversion, light‐harvesting and spin transport, and so forth. In recent years, time‐dependent density matrix renormalization group (TD‐DMRG) has emerged as a general, numerically accurate and efficient method for high‐dimensional full‐quantum dynamics. This review will cover the fundamental algorithms of TD‐DMRG in the modern framework of matrix product states (MPS) and matrix product operators (MPO), including the basic algebra with respect to MPS and MPO, the novel time evolution schemes to propagate MPS, and the automated MPO construction algorithm to encode generic Hamiltonian. Most importantly, the proposed method can handle the mixed state density matrix at finite temperature, enabling quantum statistical description for molecular aggregates. We demonstrate the performance of TD‐DMRG by benchmarking with the current state‐of‐the‐art methods for simulating quantum dynamics of the spin‐boson model and the Frenkel–Holstein(–Peierls) model. As applications of TD‐DMRG to real‐world problems, we present theoretical investigations of carrier mobility and spectral function of rubrene crystal, and the radiationless decay rate of azulene with an anharmonic potential energy surface.This article is categorized under:

Virtual shaft‐based synchronous analysis for bearing damage detection and its application in wind turbines
Authors: Zhang Baoqiang , Zhang Fanghong , Luo Huageng 
Published: March 2022

AbstractA novel method for bearing damage detection is introduced in this paper. In conventionally operated bearings, when a bearing component is damaged, precise frequency response features are available for associating with the damaged components. In some applications such as in wind turbines, the speed of the shaft is very low, and the frequency contents of the damage‐induced impulsive response are low as well. Therefore, those damage‐induced vibration responses are mixed up with gearbox operational responses and hence unable to be separated with simple band‐pass or high‐pass filters. Hence, it is difficult to obtain the expected results by directly applying the traditional bearing fault diagnosis analysis methods, such as the acceleration enveloping analysis. The method proposed in this paper is to use a synthesized synchronous averaging method, which converts the bearing response from the physical shaft cycle domain into a virtual shaft cycle domain. The bearing damage feature response is generally not synchronized with the physical shaft, but in the synthesized virtual shaft, the bearing damage feature response becomes synchronous, while the signals originally synchronized with the physical shaft become nonsynchronous. Therefore, the synchronous averaging can be applied to enhance the signal‐to‐noise ratio of the bearing damage signature. Once the signal has been cleaned up in the virtual shaft cycle domain, it is then converted back into the physical shaft cycle domain for further analysis. Both numerical simulations and a wind turbine field example have been used to demonstrate the procedure and verify the feasibility for the proposed method.
Partial denitrification–anammox (PdNA) application in mainstream IFAS configuration using raw fermentate as carbon source

Published: March 2022

AbstractThis research examined the feasibility of raw fermentate for mainstream partial denitrification–anammox (PdNA) in a pre‐anoxic integrated fixed‐film activated sludge (IFAS) process. Fermentate quality sampled from a full‐scale facility was highly dynamic, with 360–940 mg VFA‐COD/L and VFA/soluble COD ratios ranging from 24% to 48%. This study showed that PdNA selection could be achieved even when using low quality fermentate. Nitrate residual was identified as the main factor driving the PdN efficiency, while management of nitrate conversion rates was required to maximize overall PdNA rates. AnAOB limitation was never observed in the IFAS system. Overall, this study showed PdN efficiencies up to 38% and PdNA rates up to 1.2 ± 0.7 g TIN/m2/d with further potential for improvements. As a result of both PdNA and full denitrification, this concept showed the potential to save 48–89% methanol and decrease the carbon footprint of water resource recovery facilities (WRRF) by 9–15%.Practitioner points

Application of PdNA with variable quality fermentate is feasible when the nitrate residual concentration is increased to enhance PdN selection.
To maximize nitrogen removed through PdNA, nitrate conversion rates need enhancement through optimization of upstream aeration and PdN control setpoints.
The IFAS PdNA process was never anammox limited; success depended on the degree of PdN achieved to make nitrite available.
Application of PdNA with fermentate can yield 48–89% savings in methanol or other carbon compared with conventional nitrification and denitrification.
Integrating PdNA upstream from polishing aeration and anoxic zones guarantees that stringent limits can be met (<5 mg N/L).
Introduction: Thinking the Korean Wave Diasporically
Authors: Yoon Kyong 
Published: March 2022

AbstractDespite increasing scholarly and media attention to the global circulation of Korean media and popular culture (the Korean Wave or Hallyu), the diasporic population has remained a grey area in the literature. As early adopters and cultural translators, diasporic Korean youth have played a pivotal role in the recent rise of the Korean Wave. Furthermore, this cultural wave can be considered metaphorically diasporic as it contributes to the exposure of global audiences to the mediated experiences of migration and hybridity, whereby the boundaries of the nation-state are questioned. As diaspora is a way of imagining borders, groups, and individuals that deal with cultural difference, the conceptual lens of diaspora can advance audience studies of Hallyu.
K-pop Diaspora
Authors: Yoon Kyong 
Published: March 2022

AbstractFor young Korean Canadians, K-pop (Korean idol pop music) is presented not only as an ethnic media form but also as a highly global media practice. The diasporic youth’s consumption of K-pop may partly fulfill their cultural nostalgia and contribute to enhancing their ethnic ties with their ancestral homeland. Moreover, they appreciate K-pop as a global sound that is considered to be youthful, kaleidoscopic, hybrid, and relatable. While feeling ethnic and cultural affinities with K-pop, the diasporic youth engage with this genre as a cultural resource for questioning the mainstream cultural frame that takes Whiteness as a norm for granted.

Published: March 2022

ZusammenfassungDas folgende Kapitel zeigt auf, wie sich die Fachmittelschule (FMS) respektive ehemalige Diplommittelschule (DMS) als Zubringerin zur tertiarisierten Lehrpersonenbildung etablieren konnte, obwohl das Gymnasium (und ab 1995 insbesondere das musisch-pädagogische Profil) als «Königsweg» galt, die FMS immer wieder Kritik ausgesetzt war und der Zugang von FMS-Absolvierenden in die Ausbildung von Primarlehrpersonen mehrmals zur Debatte stand. Entlang von drei besonders von Unsicherheit geprägten Situationen als «kritischen Momenten» wird aufgezeigt, welche Dynamiken und Prozesse letztendlich zur Institutionalisierung der FMS Pädagogik als Zubringerin zur Ausbildung von Primarlehrpersonen an PH führten.
One-dimensional Quantum Gravity and the Schwarzian theory
Authors: Anninos Dionysios , Hofman Diego M. , Vitouladitis Stathis 
Published: March 2022

Abstract
We develop a model of one-dimensional (Conformal) Quantum Gravity. By discussing the connection between Goldstone and gauge theories, we establish that this model effectively computes the partition function of the Schwarzian theory where the SL(2, ℝ) symmetry is realized on the base space. The computation is straightforward, involves a local quantum measure and does not rely on localization arguments. Non-localities in the model are exclusively related to the value of fixed gauge invariant moduli. Furthermore, we study the properties of these models when all degrees of freedom are allowed to fluctuate. We discuss the UV finiteness properties of these systems and the emergence of a Planck’s length.
