Integration of Biostimulants Alongside Various Advanced Nitrogen Fertilization Practices Improve the Yield, Quality, and Sustainability of Malting Barley in Mediterranean Conditions

open access: yesAgronomy
Barley (Hordeum vulgare L.) is a key cereal crop for malting and brewing, where grain plumpness and optimal grain protein concentration (GPC) are essential quality traits.

Topological Convergence: A Z30 Modular Partition of the Cosmic Energy Budget Derived from Heterotic String

open access: yes
Abstract: Standard Lambda-CDM cosmology successfully parameterizes the universe but lacks a first-principles derivation for its energy density components. Following recent work on arithmetic interferometry and topological phase structures, we propose the hypothesis of Universal Topological Convergence.

Universal Topological Convergence: A Z30 Modular Partition of the Cosmic Energy Budget Derived from Heterotic String Compactification

open access: yes
Standard \( \Lambda \)CDM cosmology successfully parameterizes the universe but lacks a first-principles derivation for its energy density components (\( \Omega_c, \Omega_b, \Omega_\Lambda \)). Following recent work on arithmetic interferometry and topological phase structures, we propose the hypothesis of \( \textit{Universal Topological Convergence} \

The Z30 Cosmic Framework: Four Exact Predictions from Heterotic String Topology Validated by DESI, Planck, and JWST

open access: yes
We present a topological framework deriving cosmic composition from the modular group Z30, emerging from SO(32) heterotic string compactification. Without free parameters, the model achieves four exact matches with 2024-2025 observations: (1) Dark matter density Ω_c = φ(30)/30 = 0.2667 (Planck: 0.2650 ± 0.0070, tension 0.24σ), (2) CMB birefringence β =

Expression patterns of mating locus genes.

open access: yes, 2013
Panels A–F show expression values from quantitative RT-PCR (qRT-PCR) experiments for indicated genes calculated as described in Materials and Methods. Each panel groups genes by their overall expression pattern as follows: A, MT+ gametic; B, MT− gametic;

Identification and Characterization of MicroRNAs Involved in Parkinson’s Disease: Potential Role as Diagnostic Biomarkers.

open access: yes, 2016
Background. MicroRNAs (miRNAs) are small non-coding RNAs of 20-22 nucleotides, involved in transcriptional and post-transcriptional regulation of gene expression and involved in Parkinson’s disease. Objective.
