Abstract Background More than 2 months have passed since the novel coronavirus disease 2019 (COVID-19) first emerged in Wuhan, China. With migration of people, epidemic has rapidly spread within China and throughout world. Due to severity epidemic, undiscovered transmission COVID-19 deserves further investigation. The aim our study hypothesized possible modes SARS-CoV-2 how virus may between two family clusters a residential building Guangzhou, Methods In cross-sectional study, we monitored...
This is the seventh part in a series of papers which we introduce and develop natural, general tensor category theory for suitable module categories vertex (operator) algebra. In this paper (Part VII), give sufficient conditions existence associativity isomorphisms.
The COVID-19 pandemic continues to impact daily life worldwide. It would be helpful and valuable if we could obtain valid information from the sequential data itself for characterizing pandemic. Here, aim demonstrate that it is feasible analyze patterns of using a time-series clustering approach. In this work, use dynamic time warping distance hierarchical cluster series new cases deaths different countries into four patterns. found geographic factors have large but not decisive influence on...
Methamphetamine is one of the most abused drugs worldwide. use disorders (MAUD) not only affect physical and mental health addicts but also increase risk suicide. Although suicide rate MAUD patients high, there little research on clinical characteristics factors in patients. So, it necessary to investigate related suicidal ideation MAUD. Using response-driven sampling (RDS), a total 10,225 MAUDs were randomly selected from April May 2023 Guangdong, China. was evaluated by Beck Scale for...
Understanding the transmission process is crucial for prevention and mitigation of COVID-19 spread. This paper contributes to knowledge by analyzing incubation period, rate from close contact infection, properties multiple-generation transmission. The data regarding these parameters are extracted a detailed line-list database 9,120 cases reported in mainland China January 15 February 29, 2020. period has mean, median, mode 7.83, 7, 5 days, and, 12.5% cases, more than 14 days. number contacts...
Cellular vehicle-to-everything (C-V2X) communication, as a part of 5G wireless communications, has been considered one the most significant techniques for Smart City. Vehicles platooning is an application City that improves traffic capacity and safety by C-V2X. However, different from vehicles travelling on highways, C-V2X could be more easily eavesdropped spectrum resource limited when converge at intersection. Satisfying secrecy rate C-V2X, how to increase efficiency (SE) energy (EE) in...
The COVID‐19 pandemic spread catastrophically over the world since spring of 2020. In this paper, a heterogeneous branching process with immigration is established to quantify human‐to‐human transmission in local communities, based on temporal and structural patterns extracted from public case disclosures by four provincial Health Commissions China. With proper parameter settings, our model matches actual chains satisfactorily and, therefore, sheds light underlying spreading mechanism....
Abstract Personalized recommendation has important implications in raising online shopping efficiency and increasing product sales. There been wide interest finding ways to provide more efficient personalized recommendations. Most existing studies focus on how improve the accuracy of algorithms or are concerned reduce perceived risks thus increase consumer satisfaction. Unlike these studies, our study begins from decision‐making process consumers, using consumers' two‐stage system preference...
Smart devices, such as tablets and phones, are revolutionizing access to healthcare services. They bringing forth the mHealth eHealth revolution, aiming empower consumers make a difference their health wellbeing by connecting data personalized analytics timely insights. However, this consumer-centric journey for smart connected is presenting challenges opportunities big research, whether in integrating developing machine learning algorithms heterogeneous longitudinal or novel systems...
In the fifth generation (5G) mobile communication system, experienced user data rate is expected to achieve at least 0.1Gbps. And connection density may be one million connections per square kilometers. To satisfy this requirement, deploying dense small cell networks as an overlay conventional macro regarded effective method. paper, we analyze deployment of cells meet with 5G requirement using stochastic geometry theory. A two-tier heterogeneous cellular network (HCN) which contains both and...
To meet the booming demand for higher data rates, Small Base Stations (SBSs) are deployed densely and irregularly, leading to rapid increases in energy consumption. Meanwhile, evolution trend of future mobile network is extending three dimensional (3D) space. Therefore, efficiency 3D ultra dense networks high significance. In this paper, we focus on analyzing with sleeping strategy network. Firstly, derive expressions coverage probability by using tool stochastic geometry, where locations...
Based on the information about more than 800 cases reported by Anhui provincial health commission February 19 2020, directional transmission relationship between confirmed patients is constructed according to contact history published in cases, and it found that majority of who can infect others are male most infected female. According analysis case information, early coronavirus disease 2019 (COVID-19) province had residence or exposure Wuhan. In later stage, spread small communities mainly...
There is sufficient evidence to support that the inter-event time distribution of human behaviors heavy tailed. This fact plays an important role in dynamics at collective levels. Recently, researchers found heavy-tailed inter-activity patterns slow down spreading significantly. In this paper, we investigate influence people's interest length on information spreading. Considering has its own period being interested in, find for small period, can enhance While large will suppress These...
In this paper we investigate the distribution of zeros Boubaker polynomials.
The global spread of the COVID-19 pandemic is changing everything in 2020. It crucial importance to characterize growth patterns during transmission. In this paper, a generalized-growth model established present evolution number total confirmed cases with time. Due effective containment, generalized reveals piecewise pattern, referred as sub-exponential and sub-linear stages. Moreover, parameters can quantify effectiveness containment trend resurgence different regions all over world. Our...
A generalized growth model is applied to fit the time series of cumulative confirmed cases between Jan. 15 Feb. 15, 2020. Moreover, same formula also susceptive and close contact from 23 The tallies with data published by National Health Commission. sub-exponential sub-linear reflect heterogeneity during transmission COVID-19, which provide reference prediction trend transmission.
Cell Range Expansion (CRE) technology provide an opportunity for more users to transfer from macro cell small in the Long Term Evolution Advanced (LTE-A) heterogeneous networks. However, these CRE located at edge of cells will be seriously interfered by cell, resulting a sharp decline their Signal Interference plus Noise Ratio (SINR). In order reduce this interference, method frequency domain self-organizing interference coordination technique combined with is proposed our paper. method,...
In the context of most challenging health crisis since World War II that is COVID-19, gaining insights into how academia has responded to this urgent challenge great significance. This paper presents academic response patterns at a global, regional, and national level from an analysis publication volume versus reported cases scientific collaboration, research focus. We also compare activity associated with newly-emerging infection related long-standing infections. Our results show community...
