Pan-genomics and the structural diversity of plant genomes
(Johns Hopkins UniversityUSA, 2021-10-22)A central task of genetics research is to uncover genotypes linked to important phenotypes. However, many genomic loci are incompletely or inaccurately represented in genetics studies, thus obscuring their function and ... -
Pancreatic Cancer Immunotherapy: T-Cell Receptor Sequencing and Personalized Gene Fusion Vaccines
(Johns Hopkins UniversityUSA, 2017-08-24)Immunotherapy has struggled to reduce the high mortality rate of pancreatic cancer,in part due to the low mutation burden and immunosuppressive microenvironment associated with the disease. Early successes have been limited ... -
Pancreatic Progenitor Cells in Mice
(Johns Hopkins UniversityUSA, 2014-07-25)We generated a novel transgenic mouse expressing a tdTomato fluorophore, as well as a Strep/Flag-tagged version of Ptf1a from the native Ptf1a locus. I crossed this mouse line with the well-characterized Pdx1-GFP mouse, ... -
PARAMETRICALLY HOMOGENIZED CONSTITUTIVE MODELS FOR TITANIUM ALLOYS
(Johns Hopkins UniversityUSA, 2020-12-21)Structural analysis of heterogeneous materials using phenomenological constitutive models, is often faced with inaccuracies stemming from the lack of connection with the material microstructure and underlying physics. Pure ... -
PARAMETRICALLY HOMOGENIZED CONTINUUM DAMAGE MECHANICS (PHCDM) MODELS FOR UNIDIRECTIONAL FIBER-REINFORCED COMPOSITES
(Johns Hopkins UniversityUSA, 2021-07-14)Fiber reinforced composites are widely used in aerospace, energy, protective armors and other applications that require materials with high strength-to-weight ratios, impact resistance, durability, etc. Damage in such ... -
Parametrically Homogenized Crystal Plasticity Model for Nickel-based Superalloys: Intragranular Microstructures To Polycrystalline Aggregates
(Johns Hopkins UniversityUSA, 2020-08-31)The deformation mechanics of nickel-based superalloys at every length scale are influenced by a unique array of dislocation mechanisms evolving at the nanoscale. The origin of the lower scale phenomena within a single ... -
PARATEXTUAL ADVANTAGES OF VERSIFIED PULSE TEXTS: THE THEORY AND PRACTICE OF WANG SHUHE'S RHYMED VERSES OF PULSE-DIAGNOSTICS IN CHINESE MEDICAL HISTORY, 11-17th CENTURIES
(Johns Hopkins UniversityUSA, 2019-10-18)This thesis addresses the issue of the relationship between theory and practice in the history of Chinese medicine through one historical example. Through problematizing and historicizing the provenance and dissemination ... -
Parent and Family Resonses to a Child Undergoing BMT During Transitions in Care
(Johns Hopkins UniversityUSA, 2016-11-04)Background Pediatric blood and marrow transplantation (BMT) is an intense treatment reserved for life-threatening oncologic, hematologic, and immunologic illnesses of childhood. While BMT offers hope for cure, the intensity ... -
