Digital Village Transformation: A Model for Relativizing Regional Disparities in the Republic of Serbia

open access: yesECONOMICS, 2019
The regional reality of the Republic of Serbia is characterized by strong regional disparities and adverse demographic trends. This situation is the result not only of inadequate actions of makers of macroeconomic policy and implementation of inefficient

Deep ALMA imaging of the merger NGC1614 - Is CO tracing a massive inflow of non-starforming gas? [PDF]

open access: yes, 2016
Observations of the molecular gas over scales of 0.5 to several kpc provide crucial information on how gas moves through galaxies, especially in mergers and interacting systems, where it ultimately reaches the galaxy center, accumulates, and feeds ...

Incorporating sperm DNA fragmentation index with computer-assisted semen morphokinematic parameters as a better window to male fertility

open access: yesChinese Journal of Physiology, 2022
This study aimed to assess (1) the reproducibility of three sperm chromatin dispersion (SCD) assays for sperm DNA fragmentation, i.e., LensHooke R10® (R10), Halosperm G2® (G2), and BASO® (BA); (2) the correlation between computer-assisted semen analyzer (

Big Bang nucleosynthesis with a stiff fluid

open access: yes, 2010
Models that lead to a cosmological stiff fluid component, with a density $\rho_S$ that scales as $a^{-6}$, where $a$ is the scale factor, have been proposed recently in a variety of contexts.

Stem respiration of Norway spruce trees under elevated CO2 concentration

open access: yesBiologia Plantarum, 2010
Measurements of stem respiration were conducted for a period of four years (1999-2002) in 14-year old Norway spruce (Picea abies [L.] Karst) trees exposed to ambient (CA) and elevated CO2 concentration (CE; ambient plus 350 μmol mol-1).

Transplantable human motor networks as a neuron-directed strategy for spinal cord injury

open access: yesiScience, 2021
Summary: To repair neural circuitry following spinal cord injury (SCI), neural stem cell (NSC) transplantation has held a primary focus; however, stochastic outcomes generate challenges driven in part by NSC differentiation and tumor formation.

Trends of precipitation extreme indices over a subtropical semi-arid area using PERSIANN-CDR [PDF]

open access: yes, 2016
In this study, satellite-based daily precipitation estimation data from precipitation estimation from remotely sensed information using artificial neural networks (PERSIANN)-climate data record (CDR) are being evaluated in Iran.

Monads, Strings, and M Theory [PDF]

open access: yes, 1997
The recent developments in string theory suggest that the space-time coordinates should be generalized to non-commuting matrices. Postulating this suggestion as the fundamental geometrical principle, we formulate a candidate for covariant second ...

Mass-to-Radius Ratio for the Millisecond Pulsar J0437-4715 [PDF]

open access: yes, 1997
Properties of X-ray radiation emitted from the polar caps of a radio pulsar depend not only on the cap temperature, size, and position, but also on the surface chemical composition, magnetic field, and neutron star's mass and radius.
