Only a subset of adults acquires specific advanced mathematical skills, such as integral calculus. The representation of more sophisticated mathematical concepts probably evolved from basic number systems; however its neuroanatomical basis is still unknown. Using fMRI, we investigated the neural basis of integral calculus while healthy participants were engaged in an integration verification task. Solving integrals activated a left-lateralized cortical network including the horizontal intraparietal sulcus, posterior superior parietal lobe, posterior cingulate gyrus, and dorsolateral prefrontal cortex. Our results indicate that solving of more abstract and sophisticated mathematical facts, such as calculus integrals, elicits a pattern of brain activation similar to the cortical network engaged in basic numeric comparison, quantity manipulation, and arithmetic problem solving.

Purpose: To explore a more effective comprehensive prevention and treatment model for children's oral health by constructing a health network platform that integrates medical information evaluation, interaction, monitoring, and prevention with oral health management as the core.
Methods: The database of Shaoxing Children's Oral Health Management Network Platform was established. The oral health survey and information entry of 7 042 second-grade children in primary school in Yuecheng District from 2021 to 2022 were conducted.

To assess the accuracy of Kidney Stone Calculator(KSC), a software designed for surgical planning, in predicting the duration of lithotripsy during flexible ureteroscopy(FURS) when using the novel pulsed-Thulium: YAG(p-Tm: YAG) laser. From February to August 2023, a single-center prospective study was conducted, including patients with kidney or ureteral stones through non-contrast computed tomography(NCCT), who underwent FURS with p-Tm: YAG laser lithotripsy. KSC used three-dimensional segmentation of the stones from NCCT images, along with an interactive user interface for laser settings, to estimate the stone volume(SV) and the lithotripsy duration(LD).

Evidence from clinical research suggests that in the first two waves of COVID-19, the virus spread rapidly through a large number of undocumented asymptomatic infections. These 'silent' infections camouflaged the actual incidence of the disease, leading to downward biases in the rates of transmission, disease prevalence, and fatality. These, in turn, had implications for how people and policymakers responded to changing infection prevalence.

Numerous special functions, including the beta function, hypergeometric functions, and other orthogonal polynomials, are closely connected to the gamma function. Recently, gamma function has been enhanced by adding a new parameter. As a consequence, this gamma is called the parametric gamma function or b-gamma function.
