Real projective spaces are nonfibrators
Topology and its Applications, 1999 Une variété fermée \(N\) de dimension \(n\) est appelée un fibrateur en codimension \(k\) si, pour toute application propre \(p\) d'une variété \(M\) de dimension \(n+k\) sur un espace métrique \(B\) de dimension finie telle que \(p^{-1}(b)\) ait la forme de \(N\) pour tout \(b\in B\), l'espace \(B\) est un ANR et \(p\) est une fibration approximative (

Molecular Oncology, EarlyView.ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

A holographic connection between strings and causal diamonds
Journal of High Energy PhysicsIn this paper we explore ideas of holography and strings living in the d + 1 dimensional Anti-de Sitter space AdS d+1 in a unified framework borrowed from twistor theory. In our treatise of correspondences between geometric structures of the bulk AdS d+1,

A real-time photogrammetric algorithm for sensor and synthetic image fusion with application to aviation combined vision [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 The paper addresses a promising visualization concept related to combination of sensor and synthetic images in order to enhance situation awareness of a pilot during an aircraft landing.

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting
Molecular Oncology, EarlyView.CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

The block structure spaces of real projective spaces and orthogonal calculus of functors
, 2006 Given a compact manifold X, the set of simple manifold structures on X x \Delta^k relative to the boundary can be viewed as the k-th homotopy group of a space \S^s (X). This space is called the block structure space of X.

A note on irreducible Heegaard diagrams
International Journal of Mathematics and Mathematical Sciences, 2006 We construct a Heegaard diagram of genus three for the real projective 3-space, which has no waves and pairs of complementary handles. The first example was given by Im and Kim but our diagram has smaller complexity.

Natural Perspective: Mapping Visual Space with Art and Science
Vision, 2018 Following its discovery in fifteenth-century Italy, linear perspective has often been hailed as the most accurate method of projecting three-dimensional visual space onto a two-dimensional picture plane.
