Visual Hallucinations (VH) are a common non-motor symptom of Parkinson's Disease (PD) and the Lewy body dementias (LBD) of Parkinson's disease with dementia (PDD) and Dementia with Lewy Bodies (DLB). The origin of VH in PD and LBD is debated: earlier studies considered a number of different possible mechanisms underlying VH including visual disorders, Rapid Eye Movement (REM) Sleep Intrusions, ...

The ventral hippocampus (VH) may have an important role in spatial memory processes and emotional behaviors through connections with the medial prefrontal cortex (mPFC) and amygdala. Although the mPFC and amygdala receive afferent projections from the VH, it has not been determined whether the individual VH neurons project to both the mPFC and the amygdala. In this study, antidromic responses t...

The frequency and distribution of thin-cap fibroatheromas (TCFA) have important clinical implications. We evaluated the frequency and distribution of TCFA identified by virtual histology intravascular ultrasound (VH-IVUS) in acute coronary syndrome (ACS) and stable angina pectoris (SAP). Preintervention 3-vessel VH-IVUS was performed in 105 patients with ACS and 107 with SAP. The length of left...

Repeated water avoidance stress (WAS) induces sustained visceral hyperalgesia (VH) in rats measured as enhanced visceromotor response to colorectal distension (CRD). This model incorporates two characteristic features of human irritable bowel syndrome (IBS), VH and a prominent role of stress in the onset and exacerbation of IBS symptoms. Little is known regarding central mechanisms underlying t...

‖f(u)− f(v)‖−1 ≤ L‖u− v‖−1. We drop the dependence of f on x to emphasis the nonlinearity in u. Let Vh ⊂ H 0 (Ω) be the linear finite element space associated to a quasi-uniform mesh Th. The nonlinear Garlerkin method is: find uh ∈ Vh such that (2) Auh = f(uh) in Vh, where A : H 0 (Ω)→ H−1(Ω) is the elliptic operator defined by −∆. We shall assume the existence and locally uniqueness of the sol...

Timely and accurate information on rice cultivation makes important contributions to the profound reform of global food agricultural system, promotes development sustainable agriculture. With all-day all-weather observing ability, synthetic aperture radar (SAR) can monitor distribution in tropical subtropical areas. To solve problem misclassification with no marked signal during flooding period...

Verrucous hemangiomas (VH) are uncommon, congenital vascular malformations of the cutaneous and subcutaneous tissues that spare the deeper subfacial structures. VH usually presents at birth and slowly grows with age. It usually presents as hyperkeratotic, scattered, bluish-red plaques or nodules of various sizes. Although the lesions mostly have a linear pattern, serpiginous and reticulat...

If u denotes a local, spatial average of u, then u′ = u − u is the associated fluctuation. Consider a time relaxation term added to the usual finite element method. The simplest case for the model advection equation ut + −→a · ∇u = f(x, t) is (uh,t + −→a · ∇uh, vh) + χ(uh, v′ h) = (f(x, t), vh). We analyze the error in this and (more importantly) higher order extensions and show that the added ...
