Published: December 2021

AbstractDeveloping orange to red purely organic luminescent materials having external quantum efficiencies (ηexts) exceeding 30% is challenging because it generally requires strong intramolecular charge transfer, efficient reverse intersystem crossing (RISC), high photoluminescence quantum yield (ΦPL), and large optical outcoupling efficiency (Φout) simultaneously. Herein, by introducing benzoyl to dibenzo[a,c]phenazine acceptor, a stronger electron acceptor, dibenzo[a,c]phenazin‐11‐yl(phenyl)methanone, is created and employed for constructing orange–red delayed fluorescence molecules with various acridine‐based electron donors. The incorporation of benzoyl leads to red‐shifted photoluminescence with accelerated RISC, reduced delayed lifetimes, and increased ΦPLs, and the adoption of spiro‐structured acridine donors promotes horizontal dipole orientation and thus renders high Φouts. Consequently, the state‐of‐the‐art orange–red organic light‐emitting diodes are achieved, providing record‐high electroluminescence (EL) efficiencies of 33.5%, 95.3 cd A−1, and 93.5 lm W‒1. By referring the control molecule without benzoyl, it is demonstrated that the presence of benzoyl can exert significant positive effect over improving delayed fluorescence and enhancing EL efficiencies, which can be a feasible design for robust organic luminescent materials.

AbstractDevelopment of pure organic molecular materials with room temperature phosphorescence (RTP) and their applications for white emitters have received significant attentions recently. Herein, a D–π–A molecule (DMACPPY) which can realize white emitting under ambient conditions both in the crystal state and the doped‐film state by combining RTP with two fluorescent emissions is reported. The white emission from the crystalline sample of DMACPPY consists fluorescence from S2 (the second excited singlet state) and S1 (the first excited singlet state) along with RTP from T1 (the first excited triplet state), namely, SST‐type white light. While, the white emission from the poly methyl methacrylate (PMMA) film doped with DMACPPY contains fluorescences from S2 and S1, and RTP from T2 (the second excited triplet state) rather than T1 (STS type). DMACPPY cannot exhibit white spectrum within alternative crystalline state since inferior RTP intensity despite similar ternary emissions. The results demonstrate that the emissive properties for excited states of DMACPPY can be tuned by changing the aggregate state from crystalline to dispersion state in PMMA film. This new RTP emitter fulfills the talent for white emitting and achieves dual‐mode white emissions, invisibly, expands the application range for pure organic and heavy atom‐free RTP materials.

AbstractDriven by the continuous search for improving performances, understanding the phenomena at the electrode/electrolyte interfaces has become an overriding factor for the success of sustainable and efficient battery technologies for mobile and stationary applications. Toward this goal, rapid advances have been made regarding simulations/modeling techniques and characterization approaches, including high‐throughput electrochemical measurements coupled with spectroscopies. Focusing on Li‐ion batteries, current developments are analyzed in the field as well as future challenges in order to gain a full description of interfacial processes across multiple length/timescales; from charge transfer to migration/diffusion properties and interphases formation, up to and including their stability over the entire battery lifetime. For such complex and interrelated phenomena, developing a unified workflow intimately combining the ensemble of these techniques will be critical to unlocking their full investigative potential. For this paradigm shift in battery design to become reality, it necessitates the implementation of research standards and protocols, underlining the importance of a concerted approach across the community. With this in mind, major collaborative initiatives gathering complementary strengths and skills will be fundamental if societal and environmental imperatives in this domain are to be met.
Determining the Effectiveness of Radiative Cooler‐Integrated Solar Cells

Published: December 2021

AbstractThe power‐conversion efficiency of solar cells (SCs) is reduced at high temperatures. A radiative cooling process can be implemented to overcome this issue. The radiative cooler (RC) presents considerable potential in the design of an ideal broadband emitter, which emits heat through the entire atmospheric transmittance window for devices with operating temperatures that significantly exceed the ambient temperature. However, the performance of these devices varies based on the type of SCs. This study aims to determine the dependency of the radiative cooling power for various types of SCs and proposes the multi‐junction SC (MJSC), which is the SC that benefits the most from RCs. The integrated cooler is designed with a micro‐grating which can enhance the emissivity within entire atmospheric transmittance window and can also lead to the light‐trapping aspect in the solar spectrum. Outdoor field tests demonstrate both the enhanced cooling performance and the power conversion efficiency of the proposed MJSC when compared to a conventional glass‐mounted MJSC under direct sunlight of ≈900 Wm−2 including a temperature drop of ≈6 °C and minimization of the variation of the open‐circuit voltage to ≈6%. Future research is expected to develop a theoretical bridge between the field of SCs and radiative cooling.

Published: December 2021

AbstractBackgroundUpper airway nitric oxide (NO) is physiologically important in airway regulation and defense, and nasal NO (nNO) levels typically exceed those in exhaled breath (fractional exhaled NO [FeNO]). Elevated concentrations of NO sampled from the nose, in turn, reflect even higher concentrations in the paranasal sinuses, suggesting a “reservoir” role for the latter. However, the dynamics of NO flux within the sinonasal compartment are poorly understood.MethodsData from 10 human subjects who had previously undergone both real‐time nNO sampling and computed tomography (CT) scanning of the sinuses were analyzed using computational fluid dynamics (CFD) methods. Modeled and observed nNO values during the initial 2‐s transient (“spike”) during nasal exhalation were then compared.ResultsExamining the initial 2‐s transient spike for each subject (as well as the pooled group), there was a statistically significant correlation between modeled and observed nNO levels, with r values ranging from 0.43 to 0.89 (p values ranging from <0.05 to <0.0001). Model performance varied between subjects, with weaker correlations evident in those with high background (FeNO) levels. In addition, the CFD simulation suggests that ethmoid sinuses (>60%) and diffusion process (>54%) contributed most to total nasal NO emissions.ConclusionAnalysis of this dataset confirms that CFD is a valuable modeling tool for nNO dynamics, and highlights the importance of the ethmoid sinuses, as well as the role of diffusion as an initiating step in sinonasal NO flux. Future model iterations may apply more generally if baseline FeNO is taken into account.

Published: December 2021

AimTo describe the transport time and timing of transfer of patients with postpartum hemorrhage to a tertiary care institution in an urban area.MethodsWe included patients with postpartum hemorrhage transferred to our hospital from a perinatal care facility. We defined transfer time as the time between the referring physician's request for transfer and the patient's arrival at our hospital. We examined transfer time and its breakdown, the shock index before and after transfer, and the prognosis.ResultsOverall, 79 patients with postpartum hemorrhage were transported to our hospital within a median (interquartile range) of 53 min (47–63 min). In 70 cases (89%), the request for transport was made before the shock index reached 1.5, and two cases had cardiac arrest during transport.ConclusionsMost patients who were transferred to our hospital were transferred according to the criteria recommended by the guideline. However, the occurrence of cardiac arrest during transport indicates the need to shorten the time from transfer requests to emergency calls by strengthening cooperation with regional perinatal care facilities.
Thermal and dielectric properties enhancement of photocurable acrylate polymers for digital light processing 3D printed electronics
Authors: Huang Ho‐Shu , Liao Ying‐Chih 
Published: December 2021

AbstractDigital light processing 3D printing has been rapidly evolving conventional manufacturing industry with the most meticulous resolution and strongest layer‐to‐layer adhesion among all additive manufacturing techniques. In this study, to improve poor polymer thermal stability and dielectric properties from prevailing methyl methacrylate‐based resin, tri‐functional trimethylolpropane tri‐acrylate (TMPTA) is introduced to form a stable polymer network. Meanwhile, monomers carrying non‐polar, bulky adamantane are added to eradicate poly‐TMPTA's notorious high cracking and warping tendency. Test results showed both high 1‐adamantyl methacrylate and 1, 3‐adamantyl di‐acrylate (ADDA) additions can print crack‐free samples. However, only ADDA addition keeps low CTE (82.86 ppm/oC, 200 ~ 260°C) and cuts down Df (0.02, 10 GHz). TMPTA polymer network modifications of both additions are explored. By contrast, poly‐MMA exhibits much higher CTE (323.44 ppm/oC) and Df (0.035). A 3D‐printed curvilinear circuit board from above resin formulation with electroplated copper circuits successfully passes lead‐free level reflow without deformation.
Mourning in quarantine

Published: December 2021

AbstractThis paper explores the effects of mourning in isolation. The authors posit that the pandemic‐induced quarantine has impacted mourning processes in a negative manner, particularly insofar as the relational aspects of mourning are concerned. Through a phenomenological study based on a survey of 56 mental health care professionals, the authors examine individual experiences of living through the pandemic while enduring loss and subsequent bereavement in socially isolative conditions. The data, accompanied by several case examples, suggests that during the pandemic loss and mourning were complicated by isolation, the lack of communal grieving rituals and the presence of an increase in mental health disorders. Furthermore, the authors hypothesize that during the Covid‐19 pandemic, the absence of positive relational support will result in a greater number of cases of delayed, stalled, and prolonged mourning, as well as Persistent Complex Bereavement.
Untangling the Indonesian tangle net fishery: Describing a data‐poor fishery targeting large, threatened rays (Superorder Batoidea)

Published: December 2021

Abstract

Shark‐like rays (Order Rhinopristiformes) are among the most threatened families of marine fish, yet little is known about their populations. These rays are normally taken as opportunistic catch in fisheries targeting other species and are thus poorly reported. One exception is the Indonesian tangle net fishery, which targets shark‐like rays.
Market surveys of Muara Angke landing site in Jakarta, north‐western Java were conducted between 2001 and 2005, and the landed catch from the tangle net fishery was recorded (the Muara Angke landing site includes landings from more than one fishery).
In total, 1,559 elasmobranchs (sharks and rays) were recorded, comprising 24 species of rays and nine species of sharks. The most abundant species landed were the pink whipray Pateobatis fai and the bottlenose wedgefish Rhynchobatus australiae, the latter being the main target species.
Catch composition varied based on differences in species catchability and may also be indicative of localized declines. The fishery was highly selective for larger sized individuals, while smaller size classes of many ray species, including the target species, were also caught in other Indonesian fisheries, resulting in fishing pressure across all age classes.
The decline of tangle net vessels in the fishery and the potential shift in catch composition in the Indonesian tangle net fishery increase concerns about the status of shark‐like rays and stingrays in Indonesia.
L2‐gain robust trajectory tracking control for quadrotor UAV with unknown disturbance
Authors: Bai Ao , Luo Yanhong , Zhang Huaguang , Li Zhe 
Published: December 2021

AbstractIn this paper, the trajectory tracking problem of the position and yaw angle of an underactuated quadrotor UAV is studied. Considering that the quadrotor UAV often encounters unknown disturbance resulted by model parameter perturbations and environmental changes, a new L2‐gain robust control method is presented based on dissipation theory. First, the dynamic model of the quadrotor UAV with disturbances is transformed by introducing three virtual control variables. In this way, the trajectory tracking control can be implemented by the dual loop control, that is, the position control loop and the attitude control loop. Then, based on dissipation inequality, the robust position controller and attitude controller are developed to guarantee the L2‐gain of the system to the unknown disturbance. It is proved that all the tracking errors are uniformly ultimate boundedness. In addition, the controller is further reconstructed by introducing a new class K functions to improve the transient and steady‐state performances of the quadrotor UAV system. In the end, two simulation examples are provided to check the validity of the control method proposed and the convergence of the quadrotor UAV trajectory tracking error.

AbstractChildren with autism spectrum disorder (ASD) are frequently diagnosed with co‐occurring medical conditions including inflammatory bowel disease (IBD). To investigate the association, we conducted a systematic review registered in PROSPERO (ID:CRD42021236263) with a random‐effects meta‐analysis. We searched PubMed, Embase, and PsycInfo (last search on January 25, 2021), and manually searched relevant publications. We included observational studies measuring the association between ASD and IBD. The primary outcome was the association (odds ratio, OR) between ASD and later development of IBD. Sensitivity analyses were conducted by quality, confounding adjustment, and study design. We performed meta‐regression analyses and assessed heterogeneity, publication bias, and quality of studies with the Newcastle‐Ottawa Scale. Overall, we included six studies consisting of eight datasets, including over 11 million participants. We found that ASD was significantly associated with subsequent incident IBD (any IBD, OR = 1.66, 95% confidence interval[CI] = 1.25–2.21, p < 0.001; ulcerative colitis, OR = 1.91, 95%CI = 1.41–2.6, p < 0.001; Crohn's disease, OR = 1.47, 95%CI = 1.15–1.88, p = 0.002). ASD and IBD were also associated regardless of temporal sequence of diagnosis (any IBD, OR = 1.57, 95%CI = 1.28–1.93, p < 0.001; ulcerative colitis, OR = 1.7, 95%CI = 1.36–2.12, p < 0.001; Crohn's disease, OR = 1.37, 95%CI = 1.12–1.69, p = 0.003). Sensitivity analyses confirmed the findings of the main analysis. Meta‐regression did not identify any significant moderators. Publication bias was not detected. Quality was high in four datasets and medium in four. In conclusion, our findings highlight the need to screen for IBD in individuals with ASD, and future research should identify who, among those with ASD, has the highest risk of IBD, and elucidate the shared biological mechanisms between ASD and IBD.Lay SummaryThis systematic review and meta‐analysis of eight observational datasets found that individuals with autism spectrum disorder (ASD) are more likely to develop any inflammatory bowel disease, ulcerative colitis, or Crohn's disease. Our findings highlight the need to screen for inflammatory bowel disease in patients with ASD and elucidate the shared biological mechanisms between the two disorders.
Decreasing face touching for children with autism spectrum disorder

Published: December 2021

AbstractFace touching is a prevalent behavior for individuals of all ages. However, frequent face touching has potential negative side effects such as the transmission of viruses, bacterial infections, and skin infections. The present investigation extended previous research by evaluating a reinforcement‐based intervention package on the reduction of face touching for children with autism spectrum disorder who tolerated face coverings (i.e., masks, face shields). The treatment package included an unsignaled, momentary differential reinforcement of other behavior procedure with prompts. Results indicated that rates of face touching decreased from baseline levels for all three children during 5‐min treatment sessions. Furthermore, low levels of face touching were observed during follow‐up sessions that were longer in duration (i.e., 15 min) across participants. Results support the utility of behavioral interventions on the reduction of potentially unsafe behaviors related to medical routines.

AbstractTransplantation of olfactory ensheathing cells (OECs) has been demonstrated to be beneficial for spinal cord injury (SCI) by modulating neuroinflammation, supporting neuronal survival and promoting angiogenesis. Besides OECs, the conditioned medium (CM) from OECs has also been proved to have therapeutic effects for SCI, indicating that the bioactive substances secreted by OECs are essential for its protective effects. Nevertheless, there is still little information regarding the underlying mechanisms. Considering that exosomes are crucial for intercellular communication and could be secreted by different types of cells, we speculated that the therapeutic potential of OECs for SCI might be partially based on their exosomes. To examine whether OECs could secret exosomes, we isolated exosomes by polyethylene glycol‐based method, and identified them by electron microscopy study, nanoparticle tracking analysis (NTA) and western blotting. In view of phagocytic ability of microglia and its distinct roles in microenvironment regulation after SCI, we then focused the effects of OECs‐derived exosomes (OECs‐Exo) on microglial phenotypic regulation. We found that the extracted OECs‐Exo could be engulfed by microglia and partially reverse the LPS‐induced pro‐inflammatory polarization through inhibiting NF‐κB and c‐Jun signaling pathways in vitro. Furthermore, OECs‐Exo were found to inhibit the polarization of pro‐inflammatory macrophages/microglia while increased the numbers of anti‐inflammatory cells after SCI. Considering that the neuronal injury is closely related to the activation state of macrophages/microglia, co‐culture of microglia and neurons were performed. Neuronal death induced by LPS‐treated microglia could be significantly alleviated when microglia treated by LPS plus OECs‐Exo in vitro. After SCI, NeuN‐immunostaining and axonal tract‐tracing were performed to assess neuronal survival and axon preservation. Our data showed that the OECs‐Exo promoted the neuronal survival and axon preservation, and facilitated functional recovery after SCI. Our findings provide a promising therapeutic strategy for SCI based on exosome‐immunomodulation.

Published: December 2021

AbstractChronic total occlusions (CTO) due to in‐stent restenosis represent a challenging lesion subset for percutaneous coronary intervention in particular when associated with coronary calcification. Sometimes CTO lesions require antegrade or retrograde dissection‐re‐entry techniques with extraplaque dilation. Recently intravascular lithotripsy (IVL) emerged as a therapeutic option for the treatment of severely calcified coronary lesions but its role in extraplaque dilation is not described. In this report, we present a case of retrograde complex percutaneous coronary chronic total occlusion revascularization accomplished by the use of extraplaque IVL necessary to externally crush a heavy calcified previous implanted stent.
