VACANCY ANNOUNCEMENTS: AN UNACKNOWLEDGED SECURITY RISK
(Johns Hopkins UniversityUSA, 2021-08-26)Do current U.S. job listings create vulnerabilities to private industries seeking to hire new talent? The hypothesis of this research study argues that many vacancy announcements present informational, organizational, and ... -
Validation of the automated segmentation for the hippocampal subfields using Large Deformation Diffeomorphic Metric Mapping on 7T MR images and its application to volumetric and shape analysis for patients with temporal lobe epilepsy
(Johns Hopkins University, 2013-09-19)This thesis first aims to validate the Large Deformation Diffeomorphic Metric Mapping (LDDMM) method used in the automated segmentation of three major subfields of the hippocampus known as Cornu Ammonis (CA), dentate gyrus ... -
Validation of the Instant Blood Pressure App
(Johns Hopkins UniversityUSA, 2016-05-03)Introduction: The application of portable technology to healthcare is known as mobile health (‘mHealth’). Instant Blood Pressure (IBP) is an mHealth app that measures blood pressure (BP) using the internal sensors in an ... -
Validity of the Beck Depression Inventory among women with HIV engaged in care: Implications for transdiagnostic psychiatry in HIV treatment
(Johns Hopkins UniversityUSA, 2021-05-03)Major depressive disorder is highly prevalent among women with HIV and is associated with decreased antiretroviral therapy adherence and increased risk of mortality. As major depressive disorder often goes undiagnosed among ... -
Valsartan Loaded Micelle for Th2 High Lung Disease Management
(Johns Hopkins UniversityUSA, 2021-05-11)Th-2 high lung disease is a family of highly heterogenous diseases, in which the type 2 lymphoid cells are stimulated to release Th2 cytokines (e.g. IL-13 and IL-4) and activate type 2 inflammation, facilitating the disease ... -
Value-driven attentional capture: Exploring the influence of reward history on involuntary attentional selection
(Johns Hopkins University, 2014-05-16)Attention selects stimuli for cognitive processing, and the mechanisms that underlie the process of attentional selection have been a major topic of psychological research for over 30 years. From this research, it has been ... -
Variability in the Experimental Response of Thermally Excited Aluminum Alloys
(Johns Hopkins UniversityUSA, 2017-12-13)The use of aluminum alloys for load bearing elements continues to expand rapidly across the marine, aviation, and commercial building industries, among others. Some factors driving this expansion are aluminum's low density, ... -
Variability, Symmetry, and Dynamics in Human Rhythmic Motor Control
(Johns Hopkins UniversityUSA, 2015-05-06)How humans and other animals control rhythmic behaviors, and locomotion in particular, is one of the grand challenges of neuroscience and biomechanics. And yet remarkably few studies address the fundamental control-systems ... -
Variable-delay Polarization Modulators for the CLASS Telescopes
(Johns Hopkins UniversityUSA, 2018-08-20)The search for inflationary primordial gravitational waves and the measurement of the optical depth to reionization, both through their imprint on the large angular scale correlations in the polarization of the cosmic ... -
Variations in protein processing lead to variations in structure and function of the HIV-1 envelope protein
(Johns Hopkins UniversityUSA, 2019-01-22)Mucosal transmission of HIV is a complex, inefficient event that leads to the seeding, and eventual disruption, of the gut-associated lymphoid tissue. The basis for the gut-tropic nature of acute HIV infection is unknown. ... -
VARIATIONS IN THE MECHANICAL, CHEMICAL, AND MICROSTRUCTURAL PROPERTIES OF ENAMEL
(Johns Hopkins University, 2015-03-11)Teeth are important in the survival of humans and animals and have functions in mastication, esthetics, speech, and protection. Teeth are composed of a hard outer covering of enamel, a mid-layer of softer dentin, and an ... -
Vascular Expansion Microscopy (VascExM): A new method for high-resolution optical imaging of the microvasculature
(Johns Hopkins UniversityUSA, 2020-08-07)Purpose: The resolution of optical images systems is restricted by the diffraction limit. In the past two decades super resolution microscopy techniques have been developed to circumvent this limitation. However, these ... -
Vasoactive mediators underlying coronary tone regulation and dysregulation
(Johns Hopkins University, 2014-12-29)This dissertation illustrates the role of nitric oxide (NO) in regulating coronary tone and how impairment of NO bioavailability not only influences coronary vasoregulation but also the roles of other vasoactive mediators, ... -
VECTOR BIOLOGY AND GENOMICS OF ANOPHELES IN SOUTHERN AND CENTRAL AFRICA
(Johns Hopkins UniversityUSA, 2018-12-18)Nchelenge District in Zambia has high malaria transmission despite intensive malaria control. The primary mosquito species contributing to transmission is Anopheles funestus s.s., a species for which genetic and genomic ... -
Veganism and the Ethics and Epistemology of Disagreement: A Neo-Pascalian Approach
(Johns Hopkins UniversityUSA, 2018-02-22)Disagreement is without a doubt one of the most universal, enduring, and oftentimes quite vexing, features of our life in common. This latter aspect, to be sure, becomes all the more evident when the particular disagreement ... -
VEGF BOUND TO HEPARIN-CONJUGATED, ELECTROSPUN FIBRIN MICROFIBER SUPPORTS ECM FORMATION AND ORIENTATION ON 3D, IN VITRO MICROVASCULAR MODEL
(Johns Hopkins University, 2014-08-08)Current three dimensional (3D) models for microvasculature fail to understand the combinatorial role nanotopography, curvature, and bound growth factors have on extracellular matrix (ECM) deposition and cell alignment. ... -
VEGF immobilization and VEGFR2 trafficking and phosphorylation: in vitro and in vivo implications
(Johns Hopkins UniversityUSA, 2017-06-19)Modern drug development is marked by high failure rates in translation to the clinic. Further, many drugs that succeed in clinical trials work for only a fraction of patients. Systems pharmacology attempts to address these ... -
