Performance of rocking systems on shallow improved sand: Shaking table testing

Frontiers in Built Environment, 2015
Recent studies have highlighted the potential benefits of inelastic foundation response during seismic shaking. According to an emerging seismic design scheme, termed rocking isolation, the foundation is intentionally under–designed to promote rocking ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

A method for optimizing and controlling rocking drillstring–assisted slide drilling

Natural Gas Industry B
Rocking the drillstring at the surface during slide drilling is a common method for reducing drag when drilling horizontal wells. However, the current methods for determining the parameters for rocking are insufficient, limiting the widespread use of ...

Rock's pill that rocked the world

South African Medical Journal, 2010
I was a rookie doctor on the goldmines in the early 1960s. Part of my duties was to look after the families in the villages of the Anglo American mines at Welkom in the Free State. Their invariably large numbers of children prompted me to enquire whether they wished to have assistance in family planning.
