From Fluorescent Probes to the Theranostics Platform
Authors: Wei Peng , Wang Qing , Yi Tao 
Published: May 2022

Comprehensive SummarySince the advent of fluorescent probes, they have been widely used in the field of life sciences. Fluorescent probes can not only light up the cells, tissues and organs, but also be used to explore the bio‐distribution of specific types of disease markers. Therefore, the development of new fluorescent probes capable of recognition of bio‐markers is extremely important for the diagnosis of the related diseases. Herein, we focus on our recent works experienced the evolution from the beginning of simply fluorescent probes to the construction of theranostics platform. We have developed a series of new fluorescent probes for the detecting and imaging of reactive oxygen species (ROS) and specific enzymes in vitro and in living cells. With the shift of the fluorescence signal from visible to near‐infrared region, we expanded the application of the fluorescent probes from in vitro to in vivo. Very recently, we further constructed theranostics platforms to combine the diagnosis immediately with the corresponding treatment.

Published: May 2022

SummaryA throne‐shaped compact ultrawideband (UWB) two‐port multiple‐input multiple‐output (MIMO) antenna operating from 2.9 to 11.5 GHz is introduced. Dual‐band rejections are created at the center frequency of 5.5 and 7.5 GHz by embedding U‐slot on the feedline and split ring resonator (SRR) on the ground plane to eliminate interference with narrowband systems of these frequencies, respectively. Low mutual coupling of −22 dB is obtained almost throughout the full band by etching a rectangular slot in a cone‐shaped stub. Procedures for achieving the UWB band as well as two stopbands are discussed in detail. Current distribution, gain and radiation pattern for the proposed antenna are also studied. Peak gain of 2.51 dBi and radiation efficiency greater than 73% is obtained. Diversity parameters confirming the MIMO characteristics are also investigated. Experimental results are obtained through a practical model in the anechoic chamber to validate the simulations.

Published: May 2022

AbstractA comprehensive understanding of river dynamics requires the grain size distribution of bed sediments and its variation across different temporal and spatial scales. Several techniques are already available for grain size assessment based on field and remotely sensed data. However, the existing methods are only applicable on small spatial scales and on short time scales. Thus, the operational measurement of grain size distribution of riverbed sediments at the catchment scale remains an open problem. A solution could be the use of satellite images as the main imaging platform. However, this would entail retrieving information at sub‐pixel scales.In this study, we propose a new approach to retrieve sub‐pixel scale grain size class information from Copernicus Sentinel‐2 imagery building upon a new image‐based grain size mapping procedure. Three Italian gravel‐bed rivers featuring different morphologies were selected for unmanned aerial vehicle (UAV) acquisitions, field surveys and laboratory analysis meant to serve as ground truth grain size data, ranging from medium sand to coarse gravel. Grain size maps on the river bars were generated in each study site by exploiting image texture measurements, upscaled and co‐registered with Sentinel‐2 data resolution.Relationships between the grain sizes measured and the reflectance values in Sentinel‐2 imagery were analysed using a machine learning framework. Results show statistically significant predictive models (MAE of ±8.34 mm and R2 = 0.92). The trained model was applied on 300 km of the Po River in Italy and allowed us to identify the gravel–sand transition occurring along this river length.Therefore, the approach presented here—based on freely available satellite data calibrated by low‐cost drone‐derived imagery—represents a promising step towards an automated surface mean grain size mapping over long river length, easily repeated through time for monitoring purposes.

Published: May 2022

Abstract9‐epi‐Artemisinin occurs as a minor by‐product when artemisinin is obtained from natural or semi‐synthetic sources. The preparation of β‐artemether from artemisinin by reduction with sodium borohydride proceeds normally even when the 9‐epimer is present. However, the 9‐epimer undergoes rearrangement to peroxy acetals. The results are ascribed to the different stabilities of the corresponding dihydro‐intermediates due to steric hindrance as suggested by quantum mechanical calculations.
Riding the wave to recovery: Relational energy as an HR managerial resource for employees during crisis recovery
Authors: Sumpter Dana McDaniel , Gibson Cristina B. 
Published: May 2022

AbstractHuman resource (HR) managers play a critical role in supporting workers during organizational crisis recovery, but this support is hampered when employee energy is drained during difficult times. We develop relational theory and practical suggestions to address how employees can generate energy from interpersonal interactions in a post‐crisis context. Drawing from interviews, field observations, and archival data of interpersonal interactions in the surf and boardsport industry in the wake of the Global Financial Crisis, we investigated individual energetic contributions and the process which generated relational energy, defined as psychological resourcefulness generated from interpersonal interactions that enhances work capacity. Our analysis revealed that in the aftermath of a crisis, employees generated relational energy by engaging in processes of perspective taking and interpersonal adjustment while engaging in crisis‐recovery work. This was particularly true when their personal contributions to the interactions were negative or neutral in valence and of low intensity. This is in contrast to assumptions in the literature and industry cultural norms, but was essential to fueling interdependent work efforts during crisis recovery. These findings extend and refine theory on energy at work to help inform HR practice by developing understanding of how the energy generated from other people can be an important resource to help sustain crisis recovery, and how HR managers can support these processes.

Published: May 2022

AbstractThe field of infant research is not immune from the reproducibility crisis in cognitive science and psychology. In their recent methodological article, Byers‐Heinlein et al. (2021) invited infant researchers to commit to produce robust findings by reporting reliability metrics for their variables of interest, improving data quality and quantity, and moving towards more sophisticated paradigms and analyses. We present a novel artificial intelligence‐enriched individualized approach that, in our view, is particularly promising to shed new light on infant and child development and promote good research practice in the field; neuroadaptive Bayesian optimization (NBO). NBO is a transformative method where the collected brain or behavioural data are processed in real time and used to identify the stimuli that maximize the individual's response. Applying NBO to infant research goes in the direction proposed by Byers‐Heinlein et al. (2021) and further, the method requires careful a priori choices that effectively correspond to preregistering the experimental design and analytic pipeline. In this commentary, we examine how the NBO approach embeds the six proposed solutions for more reliable infant research, encouraging transparency of the planned analyses and robustness of findings.
Sulfur‐containing polymer cathode materials: From energy storage mechanism to energy density
Authors: Zou Rong , Liu Wenwu , Ran Fen 
Published: May 2022

AbstractBesides lithium‐ion batteries, it is imperative to develop new battery energy storage system with high energy density. In conjunction with the development of Li‐S batteries, emerging sulfur‐containing polymers with tunable sulfur‐chain length and organic groups gradually attract much attention as cathode materials. This can avoid the problems that are impeding the development of the typical Li‐S batteries, such as volume expansion, active material dissolution, shuttle effect, and so on. This review aims to generalize the type of sulfur‐containing polymers and the working principles in Li‐S batteries. The sulfur‐containing polymers (R‐Sn‐R) with different sulfur‐chain length (n > 6, n ≤ 2, and 3 ≤ n ≤ 6) are summarized. It also discusses several organic groups such as phenyl rings, N‐heterocycles, and unique structure with cross‐linked networks and multi‐micropores skeleton. This review also explores other strategies of sulfur‐containing polymers in the rest of Li‐S batteries, providing a summary of the advantages of sulfur‐containing polymers, recent development, in‐depth discussion of the mechanism in Li‐S batteries, and organic group‐structure‐performance relationship. This review would have guidelines for future development of sulfur‐containing polymers in Li‐S batteries.image
CEO firm‐related wealth, managerial horizon, and earnings management
Authors: Ngo Anh , Guha Sanjib , Pham Chuong , Chung Philip 
Published: May 2022

AbstractThis paper examines the effects of the managerial horizon, CEO pay‐performance sensitivity, and CEO firm‐related wealth on earnings management. Using two measures of pay‐performance sensitivity (CEODelta and CEOVega) in our regression analysis, we find that CEO pay‐performance sensitivity significantly affects earnings management in the early years of the CEO's services, not in retirement years. We further examine the earnings management behavior surrounding the retirement years and find that the pay‐performance sensitivity of CEO compensation is negatively associated with earnings management. Furthermore, the closer the retirement year, the lower level of earnings management observed in our sample. Finally, we further examine whether the CEOs’ firm‐related wealth affects earnings management during CEO tenure and find that CEO's firm‐related wealth also has a pronounced effect on earnings management during the CEO tenure.
Corporate site visits and financial report quality

Published: May 2022

AbstractThis study examines the association between corporate site visits and visited firms’ financial reporting quality. Using a sample of publicly listed firms in China for the years 2009 through 2018 and four different measures of financial reporting quality, we find that firms receiving more site visits have higher financial reporting quality. Specifically, we find that corporate site visits are associated with a lower level of accrual‐based earnings management and a lower likelihood of financial violations and financial restatements. Moreover, we document a positive association between corporate site visits and the evaluation of earnings disclosure quality. We also find some evidence that the positive association between site visits and financial reporting quality is more pronounced among firms with greater institutional ownership and among state‐owned enterprises. Taken together, our findings underscore the monitoring role of corporate site visits in enhancing visited firms’ financial reporting quality. This research could be of interest to regulators and institutional investors by providing insight into assessing the benefits of selective access events that may influence the quality of financial reports.
Examining the role of brooding, distress, and negative urgency in dysregulated behaviors: A cross‐sectional study in treatment‐seeking young people
Authors: Borg Dana , Hall Kate , Youssef George J. , Sloan Elise , Graeme Liam , Moulding Richard 
Published: May 2022

AbstractObjectiveDysregulated behaviors including substance use, disordered eating, and nonsuicidal self‐injury (NSSI) have significant negative implications for individuals and health systems. It is therefore paramount to understand factors influencing behavioral dysregulation, to inform prevention and treatment approaches. The literature suggests that distress and rumination (brooding) prompt individuals to engage in behavioral dysregulation for distraction (Emotional Cascade Model), although these concepts have limited investigation in clinical, treatment‐seeking samples, particularly alongside negative urgency. This cross‐sectional study sought to examine the relationships of brooding, distress, and negative urgency with behavioral dysregulation, as well as the moderating effect of negative urgency between brooding and behavioral dysregulation, in treatment‐seeking young people.MethodA total of 385 treatment‐seeking young people completed cross‐sectional, self‐report measures of distress, rumination, negative urgency, and engagement in dysregulated behaviors (NSSI, alcohol use, drug use, binge eating, and purging) over the past 1−3 months.ResultsStructural equation modeling revealed that only negative urgency, and not brooding or distress, had a significant positive relationship with behavioral dysregulation. Negative urgency did not significantly moderate the relationship between brooding and behavioral dysregulation.ConclusionsThese findings reinforce the importance of considering negative urgency in the conceptualization, prevention, and treatment of behavioral dysregulation, and contribute to the knowledge of the relationship between brooding and various dysregulated behaviors within a treatment‐seeking sample.
Experiences with police in the community: Racial/ethnic differences in negative encounters and coping reactions

Published: May 2022

AbstractAimsThis investigation explores police encounters and police‐related coping responses, and the extent to which these relations are impacted by race/ethnicity and beliefs about state authority.MethodsIn two large, diverse samples of undergraduates reporting on their recent experiences in the community, race, experiences with police, and views of police were analyzed as predictors for coping with police presence; attitudes about authority were added in the latter study to explore how views of authority affect interpretation of police encounters and later coping.ResultsNegative experiences with police differed by race and consistently predicted coping with police presence. There was a marginal interaction between views of authority and negative experiences with police, with greater stress response at lower levels of authoritarian attitudes.ConclusionsThis report clarifies interactions with police from the civilian perspective. It suggests individual attitudes meaningfully affect interpretation of police encounters and, in line with recent research recommendations, highlights the need to better understand police encounters as stressors, particularly in relation to race and ethnicity.
Deubiquitinating enzyme USP9X regulates metastasis and chemoresistance in triple‐negative breast cancer by stabilizing Snail1

Published: May 2022

AbstractBreast cancer is one of the most common malignancies in women worldwide. Triple‐negative breast cancer (TNBC) is a highly aggressive and metastatic subtype that has the characteristics of easy recurrence, poor prognosis as well as lack of targeted therapeutics. Snail1, a key factor regulating epithelial–mesenchymal transition (EMT) process, contributing to metastasis and chemoresistance in human cancers. However, the molecular mechanism of Snail1 stabilization in cancers is not fully understood. Here, we demonstrate that the deubiquitinating enzyme USP9X deubiquitinates and stabilizes Snail1, thereby promoting metastasis and chemoresistance. The depletion and pharmacological inhibition of USP9X by WP1130, an inhibitor of USP9X, downregulate endogenous Snail1 protein, inhibit cell migration, invasion, metastasis, and increase cellular sensitivity to cisplatin and paclitaxel both in vitro and in vivo, whereas the reconstitution of Snail1 in cells with USP9X depletion at least partially reverses these phenotypes. Overall, our study establishes the USP9X‐Snail1 axis as an important regulatory mechanism of breast cancer metastasis and chemoresistance and provides a rationale for potential therapeutic interventions in the treatment of TNBC.
Givers eschew gifts that are inferior to their own: How social norms, regulatory focus, and concerns about offending lead givers astray
Authors: Givi Julian , Das Gopal 
Published: May 2022

AbstractWe explore gift givers' and gift recipients' preferences concerning gifts that compare unfavorably to givers' own products. Across eight studies, we demonstrate that givers refrain from giving gifts that compare unfavorably to their own possessions more often than recipients prefer. This effect emerges because givers are more prevention‐focused (less promotion‐focused) than recipients and wish to avoid offending recipients by violating a corresponding social norm that our results suggest is of less concern to those receiving their gift. We find evidence for this two‐stage process through both mediation and moderation. This research adds to the gift giving literature by examining a new type of gifting decision, documenting a novel giver–recipient preference asymmetry, and shedding light on the roles that social norms, regulatory focus, and offensiveness play in gift giving.
The protective role of father behaviour in the relationship between maternal postnatal depression and child mental health

Published: May 2022

AbstractBackgroundMaternal depression, especially when severe and long‐lasting, is associated with adverse mental health outcomes in children. We aimed to assess, for children of mothers with persistent postnatal depression symptoms, whether positive father behaviours would decrease risk for conduct and emotional symptoms.MethodsUsing data from 4009, mother–father–child trios from the Avon Longitudinal Study of Parents and Children we examined associations between maternal depression trajectories and positive father behavioural profiles across the postnatal period (child age: 2–21 months), and child conduct and emotional symptom trajectories across middle childhood (child age: 3.5–11 years).ResultsPositive father behaviour was much less common in families where mothers experienced high‐persistent depression symptoms (33%) than in families where mothers did not (56%); of note, these fathers also had higher levels of depression symptoms. Using person‐level analysis, exposure to high‐persistent maternal depression symptoms increased child risk for a high trajectory of both conduct (odds ratio, 2.69; 95% CI: 2.00, 3.60) and emotional symptoms (odds ratio, 2.47; 95% CI: 1.83, 3.31). However, positive father behaviour (toward child and mother) reduced the odds of following high trajectories of conduct symptoms by 9% (x = 4.52, p < .001) and of emotional symptoms by 10% (x = 4.12, p < .001), even after controlling for father depression symptoms. Using variable‐level analysis, we did not identify an interaction between maternal depression and positive father behaviour. For conduct problems, we identified a direct effect of positive father behaviour and lower conduct problems. For emotional symptoms, father behaviour interacted with child age, where the largest decrease was seen at age 9, when symptoms were highest across the sample.ConclusionsPositive father behaviour can be protective against chronic mental health problems for children exposed to persistent maternal postnatal depression symptoms.
