The SIESTA method for ab initio order-N materials simulation [PDF]

open access: yes, 2001
We have developed and implemented a selfconsistent density functional method using standard norm-conserving pseudopotentials and a flexible, numerical linear combination of atomic orbitals basis set, which includes multiple-zeta and polarization orbitals.

Macroeconomic announcements, communication and order flow on the Hungarian foreign exchange market [PDF]

open access: yes, 2009
We investigate the relation between the intradaily HUF/EUR exchange rate on the one hand and news announcements and order flow on the other hand. We extend the existing literature on foreign exchange market microstructure by considering a small open ...

Enhancing magnetic stripe order in iron pnictides by RKKY exchange interactions

open access: yes, 2014
Recent experimental studies have revealed several unexpected properties of Mn-doped BaFe2As2. These include extension of the stripe-like magnetic (pi,0) phase to high temperatures above a critical Mn concentration only, the presence of diffusive and ...

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,

Relativistic Effects and the Role of Heavy Meson Exchange in Deuteron Photodisintegration [PDF]

open access: yesFew Body Syst. 24 (1998) 123-138, 1997
Relativistic effects and the role of heavy meson exchange in deuteron photodisintegration are studied systematically for photon energies below the pion production threshold. In a (p/M)-expansion, all leading order relativistic one-body and pi-exchange as well as all static heavy meson exchange currents consistent with the Bonn OBEPQ model are included.

Macrospin dynamics in antiferromagnets triggered by sub-20 femtosecond injection of nanomagnons

open access: yesNature Communications, 2016
Magnetic order in nature is defined by the exchange interaction, however its understanding on the ultrafast- and nanometer-scales is limited. Here, the authors follow the femtosecond sub-nanometer dynamics of the antiferromagnetic order parameter in ...

Nonequilibrium Transport in Superconductor/Ferromagnet/Superconductor Diffusive Junctions: Interplay between Proximity Effect and Ferromagnetism

open access: yes, 2006
The theory of the I-V characteristics in diffusive superconductor/weak ferromagnet/superconductor (SFS) junction is developed. We show that the exchange field $h$ of the ferromagnet manifests itself as an additional conductance peak at $eV \sim \Delta+h$

Chiral $2\pi$-exchange NN-potentials: Two-loop contributions [PDF]

open access: yes, 2001
We calculate in heavy baryon chiral perturbation theory the local NN-potentials generated by the two-pion exchange diagrams at two-loop order. We give explicit expressions for the mass-spectra (or imaginary parts) of the corresponding isoscalar and ...

CircCCNB1 inhibits vasculogenic mimicry by sequestering NF90 to promote miR‐15b‐5p and miR‐7‐1‐3p processing in nasopharyngeal carcinoma

open access: yesMolecular Oncology, EarlyView.
CircCCNB1 expression is down‐regulated in nasopharyngeal carcinoma (NPC); thus, less NF90 protein is bound to circCCNB1 and more binds to pri‐miRNAs, blocking their (pri‐miRNAs) binding to DGCR8 and inhibiting the processing and generation of miR‐15b‐5p/miR‐7‐1‐3p. Furthermore, decreased miR‐15b‐5p/miR‐7‐1‐3p promotes the expression of the target genes
