Mathematical relativity [PDF]

open access: yesarXiv, 2020
Lecture notes written for a one-semester course in mathematical relativity aimed at mathematics and physics students. Not meant as an introduction to general relativity, but rather as a complementary, more advanced text.

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

open access: yesMolecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

General Relativity by Kawaguchi geometry

open access: yesEPJ Web of Conferences, 2013
We construct a parameterisation invariant Lagrange theory of fields up to second order by using multivector bundles and Kawaguchi geometry. In this setup, the spacetime is an dynamical object which is a submanifold of the greater manifold, and the actual

Galilean relativity, special relativity and the work-kinetic energy theorem revisited [PDF]

open access: yesarXiv, 2007
Transformation equations for the kinetic energy of the same bullet in Galileo's and Einstein's special relativity are derived. The special relativity result is extended to the case of a photon.

Loss of SETD2 in wild‐type VHL clear cell renal cell carcinoma sensitizes cells to STF‐62247 and leads to DNA damage, cell cycle arrest, and cell death characteristic of pyroptosis

open access: yesMolecular Oncology, EarlyView.
Vulnerability to the small molecule STF‐62247 is observed in SETD2‐inactivated VHL‐positive clear cell renal cell carcinoma (ccRCC) cells. DNA damage and loss of CDC25A leads to cell cycle arrest in S phase. Cleavage of caspase‐3 (CASP3) and gasdermin E (GSDME) suggests cell death by pyroptosis.

Tests of Gravity Using Lunar Laser Ranging

open access: yesLiving Reviews in Relativity, 2010
Lunar laser ranging (LLR) has been a workhorse for testing general relativity over the past four decades. The three retroreflector arrays put on the Moon by the Apollo astronauts and the French built arrays on the Soviet Lunokhod rovers continue to be ...

Obesity alters the fitness of peritumoral adipose tissue, exacerbating tumor invasiveness in renal cancer through the induction of ADAM12 and CYP1B1

open access: yesMolecular Oncology, EarlyView.
Tumor microenvironment drives cancer formation and progression. We analyzed the role of human cancer‐associated adipocytes from patients with renal cell carcinoma (RCC) stratified as lean, overweight, or obese. RNA‐seq demonstrated that, among the most altered genes involved in the tumor–stroma crosstalk, are ADAM12 and CYP1B1, which were proven to be ...

Mathematical challenges of General Relativity [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2007
We give an overview of some of the main open problems in General Relativity as well as some new results concerning the bounded L2 curvature conjecture.

Perturbative dynamics of quantum general relativity [PDF]

open access: yesarXiv, 1997
The quantum theory of General Relativity at low energy exists and is of the form called "effective field theory". In this talk I describe the ideas of effective field theory and its application to General Relativity.

Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

open access: yesMolecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon
