AbstractHalide‐perovskite‐based mechanical energy harvesters display excellent electrical output due to their unique ferroelectricity and dielectricity. However, their high toxicity and moisture sensitivity impede their practical applications. Herein, a stretchable, breathable, and stable nanofiber composite (LPPS‐NFC) is fabricated through electrospinning of lead‐free perovskite/poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) and styrene–ethylene–butylene–styrene (SEBS). The Cs3Bi2Br9 perovskites serve as efficient electron acceptors and local nucleating agents for the crystallization of polymer chains, thereby enhancing the electron‐trapping capacity and polar crystalline phase in LPPS‐NFC. The excellent energy level matching between Cs3Bi2Br9 and PVDF‐HFP boosts the electron transfer efficiency and reduces the charge loss, thereby promoting the electron‐trapping process. Consequently, this LPPS‐NFC‐based energy harvester displays an excellent electrical output (400 V, 1.63 µA cm−2, and 2.34 W m−2), setting a record of the output voltage among halide‐perovskite‐based nanogenerators. The LPPS‐NFC also exhibits excellent stretchability, waterproofness, and breathability, enabling the fabrication of robust wearable devices that convert mechanical energy from different biomechanical motions into electrical power to drive common electronic devices. The LPPS‐NFC‐based energy harvesters also endure extreme mechanical deformations (washing, folding, and crumpling) without performance degradation, and maintain stable electrical output up to 5 months, demonstrating their promising potential for use as smart textiles and wearable power sources.

AbstractAside from band gap reduction, little is understood about the effect of the tin‐for‐lead substitution on the fundamental optical and optoelectronic properties of metal halide perovskites (MHPs), especially when transitioning from 3D to lower dimensional structures. Herein, we take advantage of the spectroscopic isolation of excitons in 2D MHPs to study the intrinsic differences between lead and tin MHPs. The exciton's spectral fine structure indicates a larger polaron binding energy in tin MHPs. Additionally, the electroabsorption responses of the 2D MHPs demonstrates that tin MHPs have exciton binding energies 1.5–2× lower than that of their lead counterparts. Despite the lower binding energy, the excitons in tin MHPs are more Frenkel‐like with small radii, small polarizabilities, and large dipole moments. These results are interpreted as consequences of small polaron formation and disorder‐induced dipole moments. This work highlights the wide range of intrinsic differences between lead and tin MHPs as well as the complexity of excited states in these systems.

Published: March 2022

AbstractIdaho is a major malt barley (Hordeum vulgare L.) producer in the United States. Production is concentrated in the semi‐arid Snake River Plain region of southern Idaho. Irrigation and fertilizer N applications are two of the most important managed factors. Research was conducted at the University of Idaho Kimberly Research & Extension Center near Kimberly, ID, to determine yield, grain quality, and malt characteristics as affected by N application rate (0, 56, 112, and 168 kg N ha−1) and final irrigation timing at Feekes 10.0 (boot; F10.0), Feekes 11.2 (soft dough; F11.2), and +7 d after Feekes 11.2 (+7F11.2). Irrigation termination at F10.0 resulted in decreased yields and unacceptable malt characteristics across N rates. Irrigation termination at F11.2 and +7F11.2 yielded 6,439 kg ha−1 at a fertilizer N application of 56 kg N ha−1, similar to higher N applications. Greater predicted yields up to 6,886 kg ha−1 were calculated by regression analysis with applications up to 147 kg N ha−1. Grain yield, protein, plumps, and test weights did not differ at any N rate for F11.2 or +7F11.2. Malt extract, free amino N, and diastatic power were similar for the F11.2 and +7F11.2 irrigations. Malt β‐glucan content did not differ up to 56 kg N ha−1 for any treatment, but reductions of up to 30 mg kg−1 were measured at higher N rates for the +7F11.2 irrigation. Results warrant further investigations into increased N applications and provide evidence of the effects of irrigation cutoff timing and N for malt barley.

AbstractMost research to date has focused on negative health outcomes associated with adverse childhood experience (ACE) exposure. The goal of the present study was to examine the relationship between ACE exposure and health information seeking, health promoting behaviours and health screening among US college students. Supplemental ACE items were added to the cross‐sectional National College Health Assessment survey administered between 2017 and 2018 with young adult (ages 18–29) college students in California (n = 3862) and Texas (n = 451). Approximately 41.9 per cent of participants reported ACE. ACE‐exposed participants were consistently and significantly less likely to receive health information from their university (p < 0.01). Using multivariable logistic regression models, reporting four or more ACE was associated with significantly lower odds of past year seatbelt use (AOR = 0.62, 95% CI = 0.44–0.89) and past 30‐day condom use during oral sex (AOR = 0.51, 95% CI = 0.27–0.97). Increases in ACE exposure were significantly associated with an increase in the odds of ever testing for HIV (AORs:1.26–2.49). Longitudinal research is needed to uncover the complex interplay between ACE, mental health, negative health behaviours and health promotion activities among young adults. Interventions to improve health promotion activities in ACE‐exposed populations could improve health and quality of life for this vulnerable population.Key Practitioner Messages

ACE exposure has a potentially harmful impact on health education efforts and health promotion outcomes including healthy behaviours and obtaining regular health screenings.
Young adults with a history of ACE exposure are more likely to report HIV screenings and more work is needed to uncover the reason for this association.
College campus health education and promotion programs should target ACE affected young adults.

AbstractAlthough there are many histopathologic prognosticators, grading of early oral tongue squamous cell carcinoma (OTSCC) is still based on morphological cell differentiation which has low prognostic value. Here we summarize the emerging histopathological markers showing powerful prognostic value, but are not included in pathology reports. Using PubMed, Scopus, Ovid Medline, and Web of Science databases, a systematic literature search was preformed to identify early OTSCC studies that investigated the prognostic significance of hematoxylin–eosin‐based histopathologic markers. Our meta‐analysis showed that tumor budding was associated with overall survival (hazard ratio [HR] 2.32; 95% CI 1.40–3.84; p < 0.01) and disease‐specific survival (DSS) (1.89; 95% CI 1.13–3.15; p = 0.02). Worst pattern of invasion was associated with disease‐free survival (DFS) (1.95; 95% CI 1.04–3.64; p = 0.04). Tumor–stroma ratio was also associated with DFS (1.75, 95% CI 1.24–2.48; p < 0.01) and DSS (1.69; 95% CI 1.19–2.42; p < 0.01). Tumor budding, worst pattern of invasion, and tumor–stroma ratio have a promising prognostic value in early OTSCC. The evaluation and reporting of these markers is cost‐effective and can be incorporated in daily practice.

AbstractIntroductionSeveral reports previously described mucormycosis co‐infection in patients with COVID‐19. As mucormycosis and COVID‐19 co‐infection might adversely affect patients' outcomes, we aimed to systematically review the related evidence and the subsequent outcomes.MethodsWe conducted a systematic review of relevant articles searching the keywords in the online databases of PubMed, Scopus, Embase, Cochrane, and Web of Science. All the records from the start of the pandemic until June 12th, 2021 underwent title/abstract and then full‐text screening process, and the eligible studies were included. We did not include any language or time restrictions for the included studies.ResultsWe found 31 eligible studies reporting 144 total cases of COVID‐19 and mucormycosis co‐infection. The nose, cranial sinuses, and orbital cavity were the most commonly involved organs, although the cerebrum, lungs, and heart were also involved in the studies. Pre‐existing diabetes mellitus (DM), as well as corticosteroid use, were the most commonly identified risk factors, but other underlying conditions and immunomodulatory drug use were also present in several cases. Aspergillus was the most commonly reported micro‐organism that caused further co‐infections in patients with concurrent COVID‐19 and mucormycosis. As most of the studies were case reports, no reliable estimate of the mortality rate could be made, but overall, 33.6% of the studied cases died.ConclusionEarly diagnosis of mucormycosis co‐infection in COVID‐19 patients and selecting the right treatment plan could be a challenge for physicians. Patients with underlying co‐morbidities, immunocompromised patients, and those receiving corticosteroids are at higher risk of developing mucormycosis co‐infection and it is crucial to have an eye examination for early signs and symptoms suggesting a fungal infection in these patients.
Multireference Methods are Realistic and Useful Tools for Modeling Catalysis
Authors: Vitillo Jenny G. , Cramer Christopher J. , Gagliardi Laura 
Published: March 2022

AbstractHighly correlated systems, in particular those that include transition metals, are ubiquitous in catalysis. The significant static correlation found in such systems is often poorly accounted for using Kohn Sham density functional theory methods, as they are single determinantal in nature. Applications to catalysis of more rigorous and appropriate multiconfigurational methods have been reported in select instances, but their use remains rare. We discuss obstacles that hinder the routine application of multireference (MR) wave function theoretical calculations to catalytic systems and the current state of the art with respect to removing those obstacles.
Computational Chemistry as a Conceptual Game Changer: Understanding the Role of London Dispersion in Hexaphenylethane Derivatives (Gomberg Systems)
Authors: Rösel Sören , Schreiner Peter R. 
Published: March 2022

AbstractThe present personal perspective sheds light on the checkered history of hexaphenylethane (HPE) and some of its key derivatives, including successes and failures in interpreting experimental as well as computational data. HPE has become a testing ground for chemical theory since the groundbreaking work of Gomberg in 1900. It sparked the growth of theoretical carbon chemistry beyond tetravalency, forced chemists to improve theory of color and chemical bonding by mesomeric resonance, and challenged the purely repulsive view on substituent effects. Understanding the origin of the instability of HPE on the one hand and the stability of the sterically much more crowded all‐meta tBu‐substituted HPE on the other hand may well be considered an important turning point in the appreciation of London dispersion (LD) and the analytical power of computational chemistry.
Association between age‐related sensory impairment with sarcopenia and its related components in older adults: a systematic review

Published: March 2022

AbstractSensory impairments and sarcopenia are both highly prevalent age‐related conditions, with the former having been postulated to contribute to the pathogenesis of the latter condition. Confirming this hypothesis may therefore help to better inform strategies for early treatment and intervention of sarcopenia. We performed a systematic review of the current literature examining the relationships between four major sensory impairments [vision (VI), hearing (HI), smell (SI), and taste (TI)] with (i) sarcopenia; and (ii) its associated components (low handgrip strength, slow gait speed, and low muscle mass). PubMed, EMBASE, CINAHL, and Cochrane Library databases were searched for observational studies investigating the relationship of VI, HI, SI, and TI with sarcopenia, low handgrip strength, slow gait speed, and low muscle mass, in adults aged 50 years or older, from inception until 24 May 2021. The risk of bias of the included studies was assessed using the Newcastle‐Ottawa Scale. This study was registered with PROSPERO, reference CRD42021247967. Ten cross‐sectional and three longitudinal population‐based studies of community‐dwelling adults (N = 68 235) were included, with five studies investigating more than one sensory impairment. In total, 8, 6, 3, and 1 studies investigated the relationship between VI, HI, SI, and TI and sarcopenia and its related components, respectively. Follow‐up duration for the longitudinal studies ranged from 4 to 11 years. All studies had a low or moderate risk of bias. We found that the presence of VI and SI, but not TI, independently increased the odds of sarcopenia. In addition, VI and SI were each independently associated with low muscle mass; and VI, HI, and SI were each independently associated with slow gait speed. However, we found inconclusive evidence for the associations between VI, HI and SI, and low handgrip strength. Our systematic review suggests a potential association between the presence of single or multiple sensory impairments and a greater likelihood of sarcopenia and/or deficits in its associated components, especially for VI, HI, and SI. Prospective studies are needed to untangle the relationship between sensory impairment and sarcopenia to better inform clinical guidelines for disease prevention and management.

Published: March 2022

AbstractFor a network, a power consumption model is an important tool to test the performance of a network process for different traffic loads. In a Passive optical network (PON), the optical network unit (ONU) is responsible for the major power consumption of PON. Both IEEE and ITU have standardized a cyclic sleep process (CSP) for ONU energy conservation. In next‐generation PON; TWDM and XGS PON, the ONU power contribution has increased further due to higher number of ONUs and ONU being tunable. Therefore, an accurate power consumption model of the CSP process for energy efficiency studies under different traffic conditions is of prime importance. The existing CSP power consumption models do not depict the CSP process accurately especially the inactivity of the ONU in the asleep and sleep aware states are not taken into account which reduce the accuracy of the model. The proposed inactivity aware model (IAM) overcomes these gaps and very accurately models the CSP process, as evident from the results, which are better than earlier model results and quite close to earlier published simulation results. The model is also validated through a simulation‐based study and the simulation results are observed to be very close to the model results with only a 5% deviation.

AbstractInkjet printing as an effective patterning deposition technology is very suitable for the fabrication of quantum dot light‐emitting diodes in next‐generation displays. However, there are still many challenges in achieving high efficiency and stability of the printed device. Herein, we reported the inkjet‐printed quantum dot light‐emitting diodes with an external quantum efficiency of over 20% and half lifetime at 1000 cd/m2 of 27,000 h for the first time. Such excellent performance is owing to the successfully optimal thickness (seven monolayers) of the extra ZnS shell, which improves the balance of the carries injection to suppress the nonradiative process for inkjet‐printed devices. Overall, this performance from inkjet‐printed quantum dot light‐emitting diodes accelerates the printed device to meet the requirements of practical display and lighting applications.

ObjectiveHigh‐risk papillary thyroid carcinoma (PTC) patients with BRAF mutation have lymph node and distant metastases and poor prognosis. Therefore, this study aims to develop a targeted ultrasound contrast agent for the BRAFV600E mutation to screen high‐risk PTC at early stage.MethodsThe targeted lipid nanobubbles carrying BRAFV600E antibody were prepared using thin film hydration‐sonication and avidin‐biotin binding methods. The physicochemical properties and stability of the targeted nanobubbles were detected by transmission electron microscopy, atomic force microscopy, and confocal laser scanning microscopy. The target binding abilities of the targeted nanobubbles in the PTC cells (B‐CPAP) overexpressed mutant BRAFV600E were evaluated by immunofluorescence staining, quantitative real‐time polymerase chain reaction, western blot, and fluorescence microscopy. After PTC tumor models overexpressed mutant BRAFV600E were established, the enhanced images of targeted lipid nanobubbles and untargeted lipid nanobubbles on PTC tumors in nude mice were observed using contrast‐enhanced ultrasound imaging.ResultsThe targeted lipid nanobubbles revealed uniform, round morphology, and good stability with a nanoscale size. Besides, BRAFV600E monoclonal antibody was observed to be combined on the surface of lipid nanobubbles. Furthermore, the targeted nanobubbles had a good targeting diagnosis ability in PTC cells with BRAFV600E overexpression. Moreover, the targeted nanobubbles had better ultrasound enhancement and peak intensity of the time‐intensity curve (P < .001) in PTC tumors with BRAFV600E overexpression as compared to the untargeted lipid nanobubbles.ConclusionThe targeted lipid nanobubbles carrying BRAFV600E antibody could be regarded as a potential targeted ultrasound contrast agent for the diagnosis of high‐risk PTC.

ObjectivesTo develop and validate a biliary atresia (BA) diagnostic score based on serum gamma‐glutamyl transferase (GGT) levels and conventional ultrasound features for discriminating BA in patients with jaundice from two centers.MethodsA total of 958 patients from one hospital were classified as the derivation cohort, and 725 patients from another hospital were classified as the validation cohort. The optimal GGT cutoff value for diagnosing BA was calculated in the derivation cohort and subsequently verified in the validation cohort. Gallbladder abnormalities and the triangular cord (TC) sign were evaluated in all patients. A BA diagnostic score was developed for diagnosing BA using the GGT levels, gallbladder abnormalities and the TC sign based on the data from the derivation cohort followed by external validation.ResultsBased on the optimal cutoff value 350.0 U/L, GGT yielded a sensitivity of 59.3% and specificity of 85.4% in diagnosing BA. The area under the receiver operating characteristic curve (AUC 0.724) was inferior to that of the gallbladder (AUC 0.911, P < .001) and comparable to that of the TC sign (AUC 0.771, P = .128). The combination of GGT and ultrasound diagnosis could help to reduce the misdiagnosis of 9 infants with BA. The BA diagnostic score yielded a sensitivity of 93.3% and specificity of 95.0% with the highest AUC in this study (0.941).ConclusionsGGT can add diagnostic value to ultrasound examination when diagnosing BA. The BA diagnostic score based on GGT, gallbladder abnormalities and the TC sign shows satisfactory discrimination abilities in BA.

Published: March 2022

3‐aminopropylphosphonate (3‐APP) is known for its use as an exogenous indicator of extracellular volume and pH in phosphorus‐31 nuclear magnetic resonance (31P NMR) studies. We used 3‐APP for estimating the extracellular volume in NMR studies of several ex vivo preparations including retrograde perfused mouse heart (n = 4), mouse liver slices (n = 2), xenograft breast cancer tumors (n = 7, MCF7), and rat brain slices (n = 4). In the former three preparations, the 3‐APP signal was stable in lineshape and intensity for hours and the chemical shift of the signal in the presence of the biological sample was the same as in the perfusion medium without the biological sample. However, in studies of brain slices, the 3‐APP signal appeared split into two, with an upfield component (0.7 ± 0.1 ppm to the left) increasing with time and showing a wider linewidth (66.7 ± 12.6 vs. 39.1 ± 7.6 Hz, the latter is of the perfusion medium signal). This finding suggests that 3‐APP inadvertently accumulated in brain slices, most likely as a membrane bound form. This observation limits the use of 3‐APP as an inert biochemical indicator in brain preparations and should be taken into account when using 3‐APP in vivo.
