Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]
PLoS Biology, 2019 During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Nodal surface semimetals: Theory and material realization [PDF]
, 2018 We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-line semimetals, in these materials, the conduction and valence bands cross ...

Topological nodal line semimetals with and without spin-orbital coupling [PDF]
, 2015 We theoretically study three-dimensional topological semimetals (TSMs) with nodal lines protected by crystalline symmetries. Compared with TSMs with point nodes, e.g., Weyl semimetals and Dirac semimetals, where the conduction and the valence bands touch

Topological transition from nodal to nodeless Zeeman splitting in altermagnets [PDF]
Physical review B, 2023 In an altermagnet, the symmetry that relates configurations with flipped magnetic moments is a rotation. This makes it qualitatively different from a ferromagnet, where no such symmetry exists, or a collinear antiferromagnet, where this symmetry is a ...

Enfermería como una postura política para la implementación de la justicia social
Acc Cietna, 2023 La justicia social no es excluyente de la enfermería, pues al brindar el cuidado se está resguardando la integridad del paciente al ir más allá de la persona enferma, ya que, a través de ésta, es que se posibilita la instauración de formas de poder más ...

Data-driven approach to designing a BCI-integrated smart wheelchair through cost–benefit analysis
High-Confidence Computing, 2023 A smart wheelchair provides mobility assistance to persons with motor disabilities by processing sensory inputs from the person. This involves accurately collecting inputs from the user during various movement activities and using them to determine their

Frequency of Different Types of Non-hodgkin Lymphoma and their Association with Demographics and Stage of Disease: An Institutional Perspective from Pakistan [PDF]
Liaquat National Journal of Cancer Care, 2020 Introduction: Lymphoma is the fifth most common cancer and affects both genders throughout the world. The purpose of current study is to find out the frequency of different types of Non-hodgkin lymphoma and its association with age, gender and stage of
