High strength Ni matrix TiO2 composites by supercritical CO2 assisted Co-electrodeposition with different sizes of TiO2 particle

Micro and Nano Engineering, 2023
High strength Ni matrix TiO2 composites are prepared by co-electrodeposition with an electrolyte composed of Ni Watts bath, surfactants, CO2 in the supercritical fluid state and various sizes of TiO2 particles.

Second Revision of the International Staging System (R2-ISS) for Overall Survival in Multiple Myeloma: A European Myeloma Network (EMN) Report Within the HARMONY Project

Journal of Clinical Oncology, 2022
PURPOSE Patients with newly diagnosed multiple myeloma (NDMM) show heterogeneous outcomes, and approximately 60% of them are at intermediate-risk according to the Revised International Staging system (R-ISS), the standard-of-care risk stratification ...

Structure of the R2 non-LTR retrotransposon initiating target-primed reverse transcription

Science, 2023
Non–long terminal repeat (non-LTR) retrotransposons, or long interspersed nuclear elements (LINEs), are an abundant class of eukaryotic transposons that insert into genomes by target-primed reverse transcription (TPRT). During TPRT, a target DNA sequence

How much should we trust R2 and adjusted R2: evidence from regressions in top economics journals and Monte Carlo simulations

Journal of Applied Economics, 2023
R2 and adjusted R2 may exaggerate a model’s true ability to predict the dependent variable in the presence of overfitting, whereas leave-one-out R2 (LOOR2) is robust to overfitting.

The role of environment and social capitals in Iranian economic growth [PDF]

Caspian Journal of Environmental Sciences, 2020
To date, only labour force and physical capital have been considered as factors of production in neoclassical growth patterns. But recently, the creation of differences in the level of production and income among countries, beyond the difference in ...

Primordial black holes in Higgs-R2 inflation as the whole of dark matter

Journal of Cosmology and Astroparticle Physics, 2021
Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included R2 term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to MPBH ∊ (10−16, 10−15) M ...

Forecasting Blood Demand Using the Support Vektor Regression Method (Case Study: Blood Transfusion Unit-PMI Central Lombok)

JISA (Jurnal Informatika dan Sains), 2023
Blood is an important component produced by the human body. Blood is also a very vital part of human survival. When blood levels in the human body are less than they should be, the way to overcome this is by donating blood or blood transfusion.

The retrotransposon R2 maintains Drosophila ribosomal DNA repeats

bioRxiv, 2021
Ribosomal DNA (rDNA) loci contain the hundreds of tandemly repeated copies of ribosomal RNA genes needed to support cellular viability. This repetitiveness makes it highly susceptible to copy number (CN) loss, threatening multi-generational maintenance ...

Occurrence of tachyonic preheating in the mixed Higgs-R2 model [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
It has recently been suggested that at the post-inflationary stage of the mixed Higgs-R2 model of inflation efficient particle production can arise from the tachyonic instability of the Higgs field.
