Online learning and virtualization are two key and complementary technologies which are increasingly used for today’s education missions. Online learning offers great accessibility to a variety of educational materials and activities, whereas virtualization allows a variety of educational software to be easily distributed using virtual machines (VMs). However, in current practice, the use of VM...

The effectiveness of Variable Messages Signs (VMS) on route guidance is assessed by a discrete probit choice model that estimates the proportion of vehicles that diverts to an alternative routes given the characteristics of different messages. A before–and–after study is also conducted to quantitatively evaluate the network wide reduction of travel time and total delay of VMS systems. We find t...

Peripheral vascular malformations (VMs) are complex and diverse vascular lesions which require individualized pretreatment planning. Pretreatment imaging using various modalities, especially magnetic resonance imaging and time-resolved magnetic resonance angiography, is a valuable tool for classifying peripheral VMs to allow proper diagnosis, demonstrate complete extent, identify the nidus, and...

Virtual machine (VM) sizes keep increasing in the cloud. However, little attention has been paid to analyze and understand the scalability of multicore applications on big VMs with multiple virtual CPUs (VCPUs), assuming that application scalability on VMs can be analyzed in the same ways as that on physical machines (PMs). The paper demonstrates that, since hardware CPU resource is dynamically...

The sorption behaviors of 4 cyclic and linear volatile methyl siloxane (VMS) compounds between water and organic matter in 3 United Kingdom soils were studied by a batch equilibrium method using(13)C-enriched sorbates. Sorption and desorption kinetics and isotherms were determined for octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), octamethyltrisiloxane (L3), and decamethy...

OBJECTIVE The aim of this study was to compare oral micronized progesterone (progesterone) with placebo as therapy for postmenopausal hot flushes and night sweats (vasomotor symptoms [VMS]). METHODS Healthy volunteer community women 1 to 10 years since final menstruation were recruited for a randomized double-blind placebo-controlled trial of progesterone (300 mg daily at bedtime) between 200...

OBJECTIVE The aim of the study was to investigate the heterogeneity of temporal patterns of vasomotor symptoms (VMS) over the menopausal transition and identify factors associated with these patterns in a diverse sample of women. METHODS The Study of Women's Health Across the Nation is a multisite longitudinal study of women from five racial/ethnic groups transitioning through the menopause. ...

BACKGROUND In catecholaminergic polymorphic ventricular tachycardia (CPVT), cardiac Purkinje cells (PCs) appear more susceptible to Ca(2+) dysfunction than ventricular myocytes (VMs). The underlying mechanisms remain unknown. Using a CPVT mouse (RyR2(R4496C+/Cx40eGFP)), we tested whether PC intracellular Ca(2+) ([Ca(2+)]i) dysregulation results from a constitutive [Na(+)]i surplus relative to V...

Background: Vasomotor symptoms (VMS; hot flashes, hot flushes) are the most common complaints of periand postmenopausal women. Therapies include various estrogens and estrogen-progestogen combinations. However, both physicians and patients became concerned about hormone-related therapies following publication of data by the Women’s Health Initiative (WHI) study and have turned to non-hormonal a...

As virtualization becomes more prevalent in the enterprise and in personal computing, there is a great need to understand the technology as well as its ramifications for recovering digital evidence. This paper focuses on trace evidence related to the installation and execution of virtual machines (VMs) on a host machine. It provides useful information regarding the types and locations of files ...
