Heterotic fluxes and supersymmetry [PDF]

open access: yes, 2014
We show that the formal alpha' expansion for heterotic flux vacua is only sensible when flux quantization and the appearance of string scale cycles in the geometry are carefully taken into account.

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

open access: yesFEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Spatial variability of nitrous oxide in the Minho and Lima estuaries (Portugal)

open access: yesScientia Marina, 2017
Nitrous oxide (N2O) is a potent long-lived greenhouse gas and estuaries represent potentially important sources of this biogas to the atmosphere. In this work, we analyse the first N2O data obtained in the Minho and Lima estuaries, and the processes and ...

Analysis of the possibility of analog detectors calibration by exploiting Stimulated Parametric Down Conversion

open access: yes, 2008
Spontaneous parametric down conversion (SPDC) has been largely exploited as a tool for absolute calibration of photon-counting detectors, i.e detectors registering very small photon fluxes. In [J. Opt. Soc. Am.

D terms from D-branes, gauge invariance and moduli stabilization in flux compactifications [PDF]

open access: yes, 2006
We elucidate the structure of D terms in N=1 orientifold compactifications with fluxes. As a case study, we consider a simple orbifold of the type-IIA theory with D6-branes at angles, O6-planes and general NSNS, RR and Scherk-Schwarz geometrical fluxes ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Heterotic type IIA duality with fluxes - towards the complete story

open access: yes, 2010
In this paper we study the heterotic type IIA duality when fluxes are turned on. We show that many of the known fluxes are dual to each other and claim that certain fluxes on the heterotic side require that the type IIA picture is lifted to M or even F ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

How scale affects N2O emissions in heterogeneous fields of a diversified agricultural landscape

open access: yesScientific Reports
Nitrous oxide (N2O) emissions from agricultural soils vary due to factors such as soil organic matter, soil moisture, and crop type, leading to short-term variations and concentrated zones of high emissions, known as “hot moments” and “hotspots.” These ...

Crescimento vegetativo de plantas cítricas no norte e noroeste do Paraná Vegetative growth of citrus trees in north an northwest of Parana

open access: yesRevista Brasileira de Fruticultura, 2005
Este trabalho avaliou, em Paranavaí e Londrina-PR, os fluxos de crescimento vegetativo dos ramos de laranjeira 'Folha Murcha' enxertada sobre limoeiro 'Cravo' (Citrus limonia Osb.), limoeiro 'Volcameriano' (Citrus volkameriana Ten. e Pasq.), tangerineira
