CR-hypersurfaces of complex projective space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
We consider compact n-dimensional minimal foliate CR-real submanifolds of a complex projective space. We show that these submanifolds are great circles on a 2-dimensional sphere provided that the square of the length of the second fundamental form is ...

One-dimensional super Calabi-Yau manifolds and their mirrors

open access: yesJournal of High Energy Physics, 2017
We apply a definition of generalised super Calabi-Yau variety (SCY) to supermanifolds of complex dimension one. One of our results is that there are two SCY’s having reduced manifold equal to ℙ 1 $$ {\mathrm{\mathbb{P}}}^1 $$ , namely the projective ...

Exploration of heterogeneity and recurrence signatures in hepatocellular carcinoma

open access: yesMolecular Oncology, EarlyView.
This study leveraged public datasets and integrative bioinformatic analysis to dissect malignant cell heterogeneity between relapsed and primary HCC, focusing on intercellular communication, differentiation status, metabolic activity, and transcriptomic profiles.

The convex real projective orbifolds with radial or totally geodesic ends: a survey of some partial results

open access: yes, 2017
A real projective orbifold has a radial end if a neighborhood of the end is foliated by projective geodesics that develop into geodesics ending at a common point.

On Real Projective Spaces as Finsler Manifolds [PDF]

open access: yesProceedings of the American Mathematical Society, 1967
Let M be a finite-dimensional C3 manifold supplied with a C2 Finsler metric ds = F(x, dx), which is not necessarily even in dx. Let p designate the induced oriented topological metric. For any p E M, the antipodal locus of p is the set A(p)= {qEMIp(p, q)_p(p, r) for all rEM}.

Time, the final frontier

open access: yesMolecular Oncology, EarlyView.
This article advocates integrating temporal dynamics into cancer research. Rather than relying on static snapshots, researchers should increasingly consider adopting dynamic methods—such as live imaging, temporal omics, and liquid biopsies—to track how tumors evolve over time.

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

open access: yesMolecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

Quantization of symplectic tori in a real polarization

open access: yes, 1996
We apply the geometric quantization method with real polarizations to the quantization of a symplectic torus. By quantizing with half-densities we canonically associate to the symplectic torus a projective Hilbert space and prove that the projective ...

Spinning particle interacting with electromagnetic and antisymmetric gauge fields in anti-de Sitter space

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Massless spinning particle model that interacts with electromagnetic and antisymmetric gauge fields in anti-de Sitter space-time is considered as a constrained Hamiltonian system.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

open access: yesMolecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.
