Early asymmetric cues triggering the dorsal/ventral gene regulatory network of the sea urchin embryo

eLife, 2014
Dorsal/ventral (DV) patterning of the sea urchin embryo relies on a ventrally-localized organizer expressing Nodal, a pivotal regulator of the DV gene regulatory network.

Self-organization of a human organizer by combined WNT and NODAL signalling

Nature, 2018
In amniotes, the development of the primitive streak and its accompanying ‘organizer’ define the first stages of gastrulation. Although these structures have been characterized in detail in model organisms, the human primitive streak and organizer remain

Two-dimensional Weyl nodal-line semimetal in a d0 ferromagnetic K2N monolayer with a high Curie temperature

Physical review B, 2020
Nodal line semimetals in two-dimensional (2-D) materials have attracted intense attention currently. From fundamental physics and spintronic applications points of view, high Curie temperature ferromagnetic (FM) ones with nodal lines robust against spin ...

Constant-Parameter Average-Value Model of Power-Electronic Voltage-Source Converters With Direct Interface in Electromagnetic Transient Simulators

IEEE Open Journal of Power Electronics
Average-value models (AVMs) of voltage-source converters (VSCs) are widely used as numerically efficient alternatives to their discrete switching models in electromagnetic transient (EMT) simulations. Recently, a so-called directly-interfaced AVM (DI-AVM)

Pretreatment Identification of Head and Neck Cancer Nodal Metastasis and Extranodal Extension Using Deep Learning Neural Networks

Scientific Reports, 2018
Identification of nodal metastasis and tumor extranodal extension (ENE) is crucial for head and neck cancer management, but currently only can be diagnosed via postoperative pathology.

Primary Nodal Gastrinomas

Archives of Pathology & Laboratory Medicine, 2000
Abstract Background.—The term primary lymph node gastrinoma was first used to describe a group of patients with gastrin-producing tumors present in lymph nodes located in a well-defined anatomic region. The patients had no known primary tumors in the pancreas or gastrointestinal tract and had disease-free survival for up to 18 years. The

Numerically Enhanced Interfacings for Average-Value Models of Voltage-Source Converters in Nodal-Based EMT Simulators

Energies
Efficient simulations of converter-dominated power systems and microgrids significantly rely on average-value models (AVMs) of the converters. The conventional AVMs of voltage-source converters (VSCs) typically require a time-step delay for interfacing ...

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

Molecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...

Symmetry demanded topological nodal-line materials [PDF]

, 2017
The realization of Dirac and Weyl physics in solids has made topological materials one of the main focuses of condensed matter physics. Recently, the topic of topological nodal line semimetals, materials in which Dirac or Weyl-like crossings along ...
