Formulation of New Equation to Estimate Productivity Index of Horizontal Wells

open access: yesIraqi Journal of Chemical and Petroleum Engineering, 2014
Significant advances in horizontal well drilling technology have been made in recent years. The conventional productivity equations for single phase flowing at steady state conditions have been used and solved using Microsoft Excel for various reservoir ...

Happiness in the Dual Society of Urban China: Hukou Identity, Horizontal Inequality and Heterogeneous [PDF]

open access: yes
This paper studies the impact of income inequality on the subjective well-being of different social groups in urban China. We classify urban social groups according to their hukou status: rural migrants, gbornh urban residents, and gacquiredh urban ...

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Classical Horizontal Inequity and Reranking: an Integrated Approach [PDF]

open access: yes
The last 20 years have seen a significant evolution in the literature on horizontal inequity (HI) and have led to two major and "rival" methodological strands, namely, classical HI and reranking.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Detection of Anticompetitive Horizontal Mergers [PDF]

open access: yes
The paper develops a four-step framework to detect anticompetitive horizontal mergers. In the first step, an estimate of the impact of the merger on the market price needs to be derived.

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Nonlinear Horizontal Diffusion for GCMs [PDF]

open access: yes, 2007
The mixing-length-based parameterization of horizontal diffusion, which was originally proposed by Smagorinsky, is revisited. The complete tendencies of horizontal momentum diffusion, the associated frictional heating, and horizontal diffusion of ...
