Pei Yongzhen et al.
An epidemic model with two parallel infectious stages and time delays and pulse vaccination is proposed. We introduce four thresholds and further obtain the conditions that the disease will be extinct or not. Corollaries show that under con...
Flexibility of Bricard's linkages and other structures via resultants and computer algebra [0.03%]
运用结式和计算机代数探讨布里卡尔连杆及其他结构的灵活性问题

Flexibility of structures is extremely important for chemistry and robotics. Following our earlier work, we study flexibility using polynomial equations, resultants, and a symbolic algorithm of our creation that analyzes the resultant. We s...
Application of Biased Metropolis Algorithms: From protons to proteins [0.03%]
偏Metropolis算法的应用：从质子到蛋白质

We show that sampling with a biased Metropolis scheme is essentially equivalent to using the heatbath algorithm. However, the biased Metropolis method can also be applied when an efficient heatbath algorithm does not exist. This is first il...
Assessment of Surgical Effects on Patients with Obstructive Sleep Apnea Syndrome Using Computational Fluid Dynamics Simulations [0.03%]
基于计算流体动力学的手术治疗阻塞性睡眠呼吸暂停低通气综合征效果评估研究

Gary C Cheng et al.
Obstructive sleep apnea syndrome is one of the most common sleep disorders. To treat patients with this health problem, it is important to detect the severity of this syndrome and occlusion sites in each patient. The goal of this study is t...
CENTER CONDITIONS AND CYCLICITY FOR A FAMILY OF CUBIC SYSTEMS: COMPUTER ALGEBRA APPROACH [0.03%]
一类cubic系统的中心条件和环域问题：计算机代数方法研究

Brigita Ferčec
Using methods of computational algebra we obtain an upper bound for the cyclicity of a family of cubic systems. We overcame the problem of nonradicality of the associated Bautin ideal by moving from the ring of polynomials to a coordinate r...
Spatial Stress and Strain Distributions of Viscoelastic Layers in Oscillatory Shear [0.03%]
黏弹性层在振荡剪切下的空间应力和应变分布规律
Brandon S Lindley,M Gregory Forest,Breannan D Smith et al.
Brandon S Lindley et al.
One of the standard experimental probes of a viscoelastic material is to measure the response of a layer trapped between parallel surfaces, imposing either periodic stress or strain at one boundary and measuring the other. The relative phas...

The analysis of multiple indicator dilution curves to estimate the rates of transport of ions and substrates across the sarcolemma of myocardial cells requires the formulation of models for the blood-ISF-cell exchanges. The fitting of model...
Patient-Specific Geometry Modeling and Mesh Generation for Simulating Obstructive Sleep Apnea Syndrome Cases by Maxillomandibular Advancement [0.03%]
下颌前移术模拟阻塞性睡眠呼吸暂停综合征的个性化几何建模与网格划分方法研究
Yasushi Ito,Gary C Cheng,Alan M Shih et al.
Yasushi Ito et al.
The objective of this paper is the reconstruction of upper airway geometric models as hybrid meshes from clinically used Computed Tomography (CT) data sets in order to understand the dynamics and behaviors of the pre- and postoperative uppe...

In advancing discrete-based computational cancer models towards clinical applications, one faces the dilemma of how to deal with an ever growing amount of biomedical data that ought to be incorporated eventually in one form or another. Mode...
An examination of Bayesian statistical approaches to modeling change in cognitive decline in an Alzheimer's disease population [0.03%]
阿尔茨海默病患者认知衰退的贝叶斯统计模型方法探究

Al Bartolucci et al.
The mini mental state examination (MMSE) is a common tool for measuring cognitive decline in Alzhiemer's Disease (AD) subjects. Subjects are usually observed for a specified period of time or until death to determine the trajectory of the d...
