Beyond the uniform creative brain: Inter-individual variability in functional connectivity correlates with creativity.

Creativity, characterized by the pursuit of uniqueness and novelty, highlights the importance of individual variability, which have been a key focus in cognitive and behavioral research on creativity. However, most studies on the neural basis of creativity have primarily focused on consistent patterns of brain activity across individuals, with little attention to the variability in brain function. In this study, inter-subject representational similarity analysis was employed to investigate the relationship between inter-individual variability in resting-state functional connectivity and creative ability.

[Callus induction, subculture, and browning inhibition of the anticancer plant ].

In order to obtain more effective cell culture parameters of Taxus anticancer plants, we optimized the callus induction and subculture conditions of the explants (stem segments with buds) of the anticancer medicinal plant by using the plant tissue culture technology and orthogonal test. Furthermore, we studied the method to inhibit browning in the culture. The results indicated that the optimal conditions for inducing callus was culture in the medium composed of B+0.

To address these deficiencies and fill the research shortages in this area, optimization of process parameters and design of cell structures are conducted to improve the mechanical performance of insoles in this topic.

From a spark to a sweeping fire: An integrative conceptual review of group turnover and a theoretical exploration of its development.

The phenomenon of group turnover has generated substantial yet disconnected scholarly interests. Despite valuable insights gained from the collective turnover literature as well as parallel research concerning related or coordinated quitting, a holistic understanding of the unique group turnover phenomenon is needed, both to synthesize existing research across multiple domains and disciplines and to kindle new inquiries regarding its dynamic nature and developmental process. To this end, we begin by conducting an integrative review of research relating to group turnover, reinterpreting it by identifying its common pathways as a function of varying triggers, temporal patterns, and departure destinations.

Characterization of PA12/HA composite scaffolds based on selective laser sintering.

Composite scaffolds have been extensively studied in bone tissue engineering, which can achieve excellent properties that cannot be obtained by a single material. In this study, the effect of hydroxyapatite (HA) on the reliability of polyamide 12 (PA12) scaffold for bone graft was explored in terms of mechanical and biological properties. Thermal properties testing showed that no physical or chemical reaction occurs in the prepared PA12/HA composite powders.

Mechanical properties and failure mechanisms of polyamide 12 gradient scaffolds developed with selective laser sintering.

Developing a functional gradient scaffold compatible with the fantastic biological and mechanical properties of natural bone tissue is imperative in bone tissue engineering. In this work, the stretch-dominated (cubical and circular) and bending-dominant (diamond and gyroid) pore styles were employed to design custom-graded scaffolds based on the curve interference method and then were fabricated by selective laser sintering (SLS) using polyamide 12 (PA12) powder. Subsequently, the mechanical behavior, failure mechanism, and energy absorption performance of porous structures were investigated via compression experiments and finite element (FE) simulation.

Safe reinforcement learning under temporal logic with reward design and quantum action selection.

This paper proposes an advanced Reinforcement Learning (RL) method, incorporating reward-shaping, safety value functions, and a quantum action selection algorithm. The method is model-free and can synthesize a finite policy that maximizes the probability of satisfying a complex task. Although RL is a promising approach, it suffers from unsafe traps and sparse rewards and becomes impractical when applied to real-world problems.

The mechanical properties and permeability of the scaffolds were then evaluated by mechanical compression experiments and computational fluid dynamics (CFD) analysis.

Two-round quasi-whispering gallery mode exciton polaritons with large Rabi splitting in a GaN microrod.

We investigate the exciton polaritons and their corresponding optical modes in a hexagonal GaN microrod at room temperature. The dispersion curves are measured by the angle-resolved micro-photoluminescence spectrometer, and two types of exciton polaritons are identified with the help of the finite-difference time-domain simulation. By changing the pump position, the photon part of the exciton polaritons is found to switch between the quasi-whispering gallery modes and the two-round quasi-whispering gallery modes.

Embeddedness and perceived oneness: Examining the effects of job embeddedness and its trajectory on employee proactivity via an identification perspective.

Although job embeddedness has consistently been shown to be associated with positive workplace behaviors, our theoretical understanding of such associations remains far behind our empirical knowledge. In particular, it is unclear how job embeddedness goes beyond its common conceptualization as "stuckness" to motivate employees' discretionary, change-oriented behaviors at work. To this end, we trace the original theoretical foundation of job embeddedness theory in field theory and establish its theoretical connection to social identity theory.

Screening and identification of key biomarkers of papillary renal cell carcinoma by bioinformatic analysis.

Background: Papillary renal cell carcinoma (PRCC) is the most common type of renal cell carcinoma after clear cell renal cell carcinoma (ccRCC). Its pathological classification is controversial, and its molecular mechanism is poorly understood. Therefore, the identification of key genes and their biological pathways is of great significance to elucidate the molecular mechanisms of PRCC occurrence and progression.

Cognitive and neural processes underlying visual creativity have attracted substantial attention. The current research uses a critical time point analysis (CTPA) to examine how spontaneous activity in the primary visual area (PVA) is related to visual creativity.

Flexible reconfiguration of functional brain networks as a potential neural mechanism of creativity.

Creativity relies on the reorganizing of multimodal information and flexible switching between different modes of thinking, suggesting an association between creativity and the reconfiguration of functional brain networks. Here, we investigated global and regional brain dynamics in high-creative (HCG, N = 22) and a low-creative (LCG, N = 20) groups during a divergent creative thinking task. We found that during the creative thinking task, the HCG demonstrated higher global network flexibility, as compared to the LCG.

In bone tissue engineering, a scaffold requires not only facilitating cell activity but also providing adequate mechanical support. One feasible approach to ensure it is to use modeling tools to design such a scaffold which is then built by additive manufacturing. In this study, curve interference was introduced to design porous scaffolds with gradient structures based on three lattice units (cubical, circular and spherical) which were then manufactured by selective laser sintering (SLS) with PA12/HA material.
