We move beyond discussing the desirability and feasibility of bridging the research–practice gap to introducing an identity perspective to explore how Chinese management researchers make sense of the research–practice gap and what kinds of career identities are constructed. We conducted a qualitative study among 34 Chinese management researchers working at or studying for a PhD at research-oriented business schools in China. The findings show that management researchers in typical Chinese higher education institutions prefer constructing a single identity (i.e., professional, scholar, or knowledge worker identity) rather than a hybrid identity such as "academic-practitioner" as studies of their Western counterparts suggest. Moreover, before seeking and emulating role models to construct their desired career identities, researchers in China studying management reflexively search for referent groups by identifying either with a narrow disciplinary group (US mainstream management researchers or traditional intellectuals) or a broad group of knowledge workers. Furthermore, this study delineates how researchers with varying career identity narratives adopt corresponding identity work strategies (i.e., redefinition, defense, and distance) suggesting that identity work strategies do not always lead to achieving or preserving positive identity.

Centromeres in most multicellular eukaryotes are composed of long arrays of repetitive DNA sequences. Interestingly, several transposable elements, including the well-known long terminal repeat centromeric retrotransposon of maize (CRM), were found to be enriched in functional centromeres marked by the centromeric histone H3 (CENH3). Here, we report a centromeric long interspersed nuclear element (LINE), Celine, in Populus species. Celine has colonized preferentially in the CENH3-associated chromatin of every poplar chromosome, with 84% of the Celine elements localized in the CENH3-binding domains. In contrast, only 51% of the CRM elements were bound to CENH3 domains in Populus trichocarpa. These results suggest different centromere targeting mechanisms employed by Celine and CRM elements. Nevertheless, the high target specificity seems to be detrimental to further amplification of the Celine elements, leading to a shorter life span and patchy distribution among plant species compared with the CRM elements. Using a phylogenetically guided approach, we were able to identify Celine-like LINE elements in tea plant (Camellia sinensis) and green ash tree (Fraxinus pennsylvanica). The centromeric localization of these Celine-like LINEs was confirmed in both species. We demonstrate that the centromere targeting property of Celine-like LINEs is of primitive origin and has been conserved among distantly related plant species. A long interspersed nuclear element retrotransposon colonizes centromeric histone H3-associated functional centromeres in Populus species. [ABSTRACT FROM AUTHOR]

Accurate prediction of agricultural product prices is instrumental in providing rational guidance for agricultural production planning and the development of the agricultural industry. By constructing an end-to-end agricultural product price prediction model, incorporating a segmented Bézier curve fitting algorithm and Long Short-Term Memory (LSTM) network, this study selects corn futures prices listed on the Dalian Commodity Exchange as the research subject to predict and validate their price trends. Firstly, corn futures prices are fitted using segmented Bézier curves. Subsequently, the fitted price sequence is employed as a feature and input into an LSTM network for training to obtain a price prediction model. Finally, the prediction results of the Bézier curve-based LSTM model are compared and analyzed with traditional LSTM, ARIMA (Autoregressive Integrated Moving Average Model), VMD-LSTM, and SVR (Support Vector Regression) models. The research findings indicate that the proposed Bézier curve-based LSTM model demonstrates significant predictive advantages in corn futures price prediction. Through comparison with traditional models, the effectiveness of this model is affirmed. Consequently, the Bézier curve-based LSTM model proposed in this paper can serve as a crucial reference for agricultural product price prediction, providing effective guidance for agricultural production planning and industry development.

Interlayer charge‐transfer (CT) in 2D atomically thin vertical stacks heterostructures offers an unparalleled new approach to regulation of device performance in optoelectronic and photonics applications. Despite the fact that the saturable absorption (SA) in 2D heterostructures involves highly efficient optical modulation in the space and time domain, the lack of explicit SA regulation mechanism at the nanoscale prevents this feature from realizing nanophotonic modulation. Here, the enhancement of SA response via CT in WS2/graphene vertical heterostructure is proposed and the related mechanism is demonstrated through simulations and experiments. Leveraging this mechanism, CT‐induced SA enhancement can be expanded to a wide range of nonlinear optical modulation applications for 2D materials. The results suggest that CT between 2D heterostructures enables efficient nonlinear optical response regulation. [ABSTRACT FROM AUTHOR]

In this work, the nonlinear optical response and the ultrafast carrier dynamics in the visible region of NbSe2 are investigated. The transient absorption (TA) spectra reveal the relaxation process, including electron–phonon scattering and phonon–phonon scattering. These results contribute to an in-depth understanding of the light-matter interactions and carrier dynamics in NbSe2 and will establish a foundation for its applications in nonlinear photonic and optoelectronic devices.

Cisplatin nephrotoxicity is an etiological factor for acute kidney injury (AKI). MicroRNA (miRNA) expression is dysregulated in cisplatin‐induced AKI (cAKI) although the underlying mechanisms are unclear. A cAKI model was established by intraperitoneally injecting cisplatin, and key miRNAs were screened using high‐throughput miRNA sequencing. The functions of key miRNAs were determined using the cell viability, live/dead, reactive oxygen species (ROS), and 5‐ethynyl‐2′‐deoxyuridine (EdU) proliferation assays. Additionally, the macrophage membrane was wrapped around a metal–organic framework (MOF) loaded with miRNA agomir to develop a novel composite material, macrophage/MOF/miRNA agomir nanoparticles (MMA NPs). High‐throughput miRNA sequencing revealed that miR‐30e‐5p is a key miRNA that is downregulated in cAKI. The results of in vitro experiments demonstrated that miR‐30e‐5p overexpression partially suppressed the cisplatin‐induced or lipopolysaccharide (LPS)‐induced downregulation of cell viability, proliferation, upregulation of ROS production, and cell death. Meanwhile, the results of in vivo and in vitro experiments demonstrated that MMA NPs alleviated cAKI by exerting anti‐inflammatory effects. Mechanistically, cisplatin downregulates the expression of miR‐30e‐5p, and the downregulated miR‐30e‐5p can target Galnt3 to activate the adenosine 5'‐monophosphate activated protein kinase (AMPK) signaling pathway, which promotes the progression of AKI. Our study found that miR‐30e‐5p is a key downregulated miRNA in cAKI. The downregulated miR‐30e‐5p promotes AKI progression by targeting Galnt3 to activate the AMPK signaling pathway. The newly developed MMA NPs were found to have protective effects on cAKI, suggesting a potential novel strategy for preventing cAKI. [ABSTRACT FROM AUTHOR]

Two-dimensional molybdenum borides (MBenes) comprise a new class of 2D transition metal borides that exhibit potential photonics applications. Recently, the synthesis of individual single-layer Mo 4/3 B 2 T x (T = O, F, OH) MBene sheets has been realized, which attracted considerable attention in optoelectronics. However, there is still a lack of understanding and regulation of the photophysical processes of Mo 4/3 B 2 T x MBene. Here, we demonstrate that Mo 4/3 B 2 T x MBene exhibits a surface termination-dependent electronic structure, carrier dynamics, and nonlinear optical response over a wide wavelength range (500-1550 nm). As prepared 2D Mo 4/3 B 2 F 2 MBene possesses a semimetal material property that exhibits a shorter intraband scattering process (<100 ps) and a considerable nonlinear optical response at a broadband cover optical communication C band at 1550 nm. These thrilling results are confirmed theoretically and experimentally. The analysis of these results adds to the regulating and understanding of the basic photophysical processes, which is anticipated to be beneficial for the further design of MBene-based photonics and nanoelectronics devices.
