Hacia un marco constructivista realista para el análisis de las relaciones internacionales desde las periferias

open access: yesColombia Internacional, 2013
This article aims to systematize and articulate, within a theoretical proposal, the problems emerging from the absence of a conceptual framework that can account for international economy, politics and security dynamics and processes of peripheral ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Approaches to the solution of a soil map of the Czech Republic at the scale 1:250 000 using SOTER methodology

open access: yesPlant, Soil and Environment, 2003
Soil map at the scale 1:250 000 was set up by means of transformation of the published and later digitised soil map of theCzechRepublic. The legend to this map reflects a new classification system of Czech soils that can easily be correlated with the ...

State of the art in the determination of the fine structure constant and the ratio $h/m_\mathrm{u}$

open access: yes, 2019
The fine structure constant $\alpha$ and the ratio $h/m_{\mathrm{u}}$ between the Planck constant and the unified atomic mass are keystone constants for the determination of other fundamental physical constants, especially the ones involved in the ...

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Relations Between Units and Relations Between Quantities [PDF]

open access: yes, 2016
The proposed revision to the International System of Units contains two features that are bound to be of special interest to those concerned with foundational questions in philosophy of science. These are that the proposed system of international units (

A Chart-Parsing Algorithm for Efficient Semantic Analysis

open access: yes, 2002
In some contexts, well-formed natural language cannot be expected as input to information or communication systems. In these contexts, the use of grammar-independent input (sequences of uninflected semantic units like e.g. language-independent icons) can

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status
