Primitive macrophages control HSPC mobilization and definitive haematopoiesis

Nature Communications, 2015
In vertebrates, haematopoietic stem/progenitor cells (HSPCs) first emerge in the aorta–gonad–mesonephros (AGM) before colonizing transitory and subsequently definitive haematopoietic organs allowing haematopoiesis throughout adult life.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

On primitive ideals in graded rings

, 2008
Let R = circle plus(infinity)(i=1) Ri be a graded nil ring. It is shown,that primitive ideals in R are homogeneous. Let A = circle plus(infinity)(i=1) Ai be a graded non-PI just-infinite dimensional algebra and let I be a prime ideal in A.

Primitive myxoid mesenchymal tumor of infancy presenting with an abdominal and thoracic mass misdiagnosed as neuroblastoma: A case report

Indian Journal of Pathology and Microbiology
Primitive myxoid mesenchymal tumor of infancy (PMMTI) is a rare soft tissue tumor that has been recently described in only a few cases. A 10-month-old boy was admitted with a mass filling the abdomen and right hemothorax.

Ornamental “borderlands”: Elisabeth Wilson and Martin Heydrich’s historiographies of “primitive” ornament [PDF]

Journal of Art Historiography, 2015
This article examines texts by Elisabeth Wilson and Martin Heydrich written in 1914 at the University of Leipzig on the subject of ‘primitive’ ornament. Both synopsize the history and literature of this field from its beginnings in the nineteenth century

Primitive and totally primitive Fricke families with applications (II) [PDF]

Journal of Mathematical Analysis and Applications, 2016
We introduce the primitivity of Fricke families, and give some examples. As its application, we first construct generators of the function field of the modular curve of level $N$ in terms of Fricke functions and Siegel functions, respectively. Furthermore, we use the special values of a certain function in a totally primitive Fricke family of level $N$

Integrated Field‐Free SOT Domain‐Wall Synapses and MTJ Stochastic Neurons for Hardware Boltzmann Machines

Advanced Functional Materials, EarlyView.
Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.

Le primitif et le mystique chez Lévy-Bruhl, Bergson et Bataille

Methodos, 2004
French human sciences at the beginning of the 20th century used to assimilate the figures of the mad person, the primitive and the child. The Author shows that this assimilation should not be interpreted in the sense of an opposition between the archaic ...

Distinct Wnt-driven primitive streak-like populations reflect in vivo lineage precursors

Development, 2014
During gastrulation, epiblast cells are pluripotent and their fate is thought to be constrained principally by their position. Cell fate is progressively restricted by localised signalling cues from areas including the primitive streak.
