Developmental language disorder (DLD) is a condition that significantly affects children's achievement but has been understudied. We aim to estimate the prevalence of DLD in Shanghai, compare co-occurrence difficulties between children with and those typical development (TD), investigate early risk factors for DLD.We estimated using data from population-based survey cluster random sampling design China. A subsample (aged 5-6 years) received an onsite evaluation, each child was categorized as...
Based on SEIR (susceptible–exposed–infectious–removed) epidemic model, we propose a modified mathematical model to describe the spread of coronavirus disease 2019 (COVID-19) in Wuhan, China. Using public data, uncertainty parameters proposed for COVID-19 Wuhan were calibrated. The control basic reproduction number was studied with posterior probability density function parameters. used inverse deduce earliest start date infection consideration lack information initial conditions model....
Excessive screen time has been associated with a higher risk for mental health problems, but whether the associations differ by content types is unclear.
Abstract Let $\mathbb{N}$ be the set of all non-negative integers. For any integer r and m , let $r+m\mathbb{N}=\{r+mk: k\in\mathbb{N}\}$ . $S\subseteq \mathbb{N}$ $n\in $R_{S}(n)$ denote number solutions equation $n=s+s'$ with $s, s'\in S$ $s \lt s'$ $r_{1}, r_{2}, m$ integers $0 r_{1} r_{2} $2\mid r_{1}$ In this paper, we prove that there exist two sets C D $C\cup D=\mathbb{N}$ $C\cap D=(r_{1}+m\mathbb{N})\cup (r_{2}+m\mathbb{N})$ such $R_{C}(n)=R_{D}(n)$ for $n\in\mathbb{N}$ if only...
Cadmium(Cd) is a heavy metal that harmful to human health. Early studies have shown cadmium can damage testicular structure, affecting testosterone synthesis and spermatogenesis. However, the effect of paternal Cd exposure on reproductive system offspring remains unclear. In this study, male 8-week C57BL/6 J mice were used as research objects, was injected intraperitoneally every other day at dose 1 mg/kg for 5 weeks, after which studied. Our results showed body weight increased faster, with...
Efficient manufacturing of recombinant adenovirus-associated virus (AAV) vectors is critical to the successful development genomic medicines. We attempted optimize AAV vector production in a producer cell line platform. In this system, helper functions required for replication and are provided via infection with replication-competent wild-type Adenovirus. To evaluate strategies reduction packaging adenovirus understand interplay during production, was compared mutant (Ad5ts149) containing...
Objective: Depression and osteoporosis are usually concurrent health problems. This study aimed to explore the development of in depressive mice model investigate beneficial effects classical herbal formula Chaihu-Shugan-San (CHSG) on brain bone. Methods: CHSG powder was prepared by spray-drying following extraction with water. The fingerprint analyzed using liquid chromatography. depressive-like established chronic unpredictable mild stress (CUMS) female mice. behaviors trabecular bone...
SPRY4 is a protein encoding gene that belongs to the Spry family. It inhibits mitogen-activated kinase (MAPK) signaling pathway and plays role in various biological functions under normal pathological conditions. The has specific structure interacts with other molecules regulate cellular behavior. serves as negative feedback inhibitor of receptor tyrosine kinases (RTK) interferes cell proliferation migration. also influences inflammation, oxidative stress, apoptosis. In different types...
Abstract Background Barthel Index (BI) is one of the most widely utilized tools for assessing functional independence in activities daily living. Most existing BI studies used populations with specific diseases (e.g., Alzheimer’s and stroke) to test prognostic factors scores; however, generalization these findings was limited when target varied. Objectives The aim present study utilize electronic health records (EHRs) data mining techniques develop a generic procedure identifying that...
We give an elementary proof of the well-known congruence $$ \binom{\frac{p-1}{2}}{\frac{p-1}{4}} \equiv \frac{2^{p-1}+1}{2} \bigg(2a-\frac{p}{2a}\bigg) \pmod{p^2}, where $p 1 \pmod{4}$ is prime and = a^2 + b^2$ with $a \pmod{4}$.
We prove that, for any $c_1,c_2,c_3\in(1,41/35)$, every sufficiently large odd number $N$ can be represented as the sum of three primes $N = p_1 + p_2 +p_3$ such that $p_i \lfloor n_{i}^{c_i}\rfloor$ some $n_i \in{\mathbb N}$ each $1 \leq i 3$. Our arguments are based on a variant Green's transference principle due to Matom\"aki, Maynard and Shao. necessary restriction estimate using Bourgain's strategy employ Harman's sieve method optimize our upper bound $c_i$.
For an odd integer $n \ge 3$ and $a\in \mathbb {Z}$ with $(a,n)=1$, let $$ \mathcal {U}_{a,n}=\biggl \{1\le x\le \frac {n-1}{2}: \{ax\}_n\ge {n+1}{2}\bigg \}, $$\mathcal {I}_{a,n}=\biggl \{(i,j): 1\le i \lt j\le {n-1}{2}\text { }\|ai\|_
We prove several extensions of the Erdos-Fuchs theorem.
We prove a Lucas-type congruence for q-Delannoy numbers.
We prove that |{1<=y<=x: y is odd and not of the form p+2^a+2^b}|>>x^{1-ε} for any ε>0, where implied constant only depends on ε.
We prove that $$ \sum_{n \leq x} \varphi([x/n])\leq\bigg(\frac{1380}{4009}+\frac{2629}{4009}\cdot\frac1{\zeta(2)}+o(1)\bigg)x\log x as $x\to\infty$, where $\varphi$ denotes the Euler totient function and $[x]$ integer part of $x$.
We obtain reasonably tight upper and lower bounds on the sum $\sum_{n \leqslant x} \varphi \left( \left\lfloor{x/n}\right\rfloor\right)$, involving Euler functions $\varphi$ integer parts $\left\lfloor{x/n}\right\rfloor$ of reciprocals integers.
Let $p_n$ denote the $n$-th prime. For any $m\geq 1$, there exist infinitely many $n$ such that $p_{n}-p_{n-m}\leq C_m$ for some large constant $C_m>0$, and $$p_{n+1}-p_n\geq \frac{c_m\log n\log\log n\log\log\log\log n}{\log\log\log n}, $$ small $c_m>0$. Furthermore, we also obtain a related result concerning least primes in arithmetic progressions.
