Breaking trend panel unit root tests [PDF]
This paper proposes Lagrange Multiplier based panel unit root tests allowing for structural breaks through simple extensions of existing group mean and combination tests. The proposed tests are more general than those previously suggested.

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.

Efficient tool path generation for root 3 subdivision surface
, 2006 An approach of three-axis NC cutter path generation for root 3 subdivision surface is proposed. A computing formula for error estimating root 3 subdivision surface is derived. Using the formula, one can predict how many steps of subdivision are necessary

Estimating Surface Area of Soybean Root Systems [PDF]
, 1969 A procedure for estimating the total root length, root surface, and root hair surface is described for greenhouse-grown soybeans. Data are presented on the extent of the root systems of 3-week and 14-week old soybeans. The possibility of correlating data

New Method for Viewing Root Surfaces [PDF]
Journal of Periodontology, 1975 A new technique, density slicing and color coding, was utilized in examining root surfaces. This technique proved to be an adjunct in evaluating tooth surfaces and appeared to have future dental application. Density slicing and color coding vividly portrays the root surface, the depth of depressions and the concentration and flow pattern of calculus ...

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.
