The flow of foreign direct investment (FDI) into a country can benefit both the investing entity and host government. This study employed panel analysis to examine the factors that determine the direction of FDI to the fast-growing BRICS (Brazil, Russia,

Cooperative effects enhance the transport properties of molecular spider teams [PDF]
Molecular spiders are synthetic molecular motors based on DNA nanotechnology. While natural molecular motors have evolved towards very high efficiency, it remains a major challenge to develop efficient designs for man-made molecular motors. Inspired by biological motor proteins like kinesin and myosin, molecular spiders comprise a body and several legs.

The restoration potential of offshore mussel farming on degraded seabed habitat
Due to the artificial structures that accumulate mussels and exclude destructive fishing practices, the seabed could be restored by the installation of mussel farming structure. After four years, there was a significantly greater abundance of mobile taxa compared to the Controls that remained open to trawling. Commercial European lobster and brown crab

The perturbed prox-preconditioned spider algorithm: non-asymptotic convergence bounds [PDF]
A novel algorithm named Perturbed Prox-Preconditioned SPIDER (3P-SPIDER) is introduced. It is a stochastic variancereduced proximal-gradient type algorithm built on Stochastic Path Integral Differential EstimatoR (SPIDER), an algorithm known to achieve near-optimal first-order oracle inequality for nonconvex and nonsmooth optimization.

Molecular Spiders with Memory [PDF]
Synthetic bio-molecular spiders with "legs" made of single-stranded segments of DNA can move on a surface which is also covered by single-stranded segments of DNA complementary to the leg DNA. In experimental realizations, when a leg detaches from a segment of the surface for the first time it alters that segment, and legs subsequently bound to these ...

Cover crops affect soybean yield components, but not grain quality
Abstract Cover cropping is mainly used to prevent soil erosion, but the effects of individual cover crops on the subsequent soybean [Glycine max (L.) Merr.] are hardly known. Therefore, two annual field trials with 15 cover crop species and bare fallow as control were conducted in semi‐arid East Austria in 2016 and 2017.

An Inductive Approach to Strongly Antimagic Labelings of Graphs [PDF]
An antimagic labeling for a graph $G$ with $m$ edges is a bijection $f: E(G) \to \{1, 2, \dots, m\}$ so that $\phi_f(u) \neq \phi_f(v)$ holds for any pair of distinct vertices $u, v \in V(G)$, where $\phi_f(x) = \sum_{x \in e} f(e)$. A strongly antimagic labeling is an antimagic labeling with an additional condition: For any $u, v \in V(G)$, if $\deg(u)

Sparse Image Reconstruction for the SPIDER Optical Interferometric Telescope [PDF]
The concept of a recently proposed small-scale interferometric optical imaging device, an instrument known as the Segmented Planar Imaging Detector for Electro-optical Reconnaissance (SPIDER), is of great interest for its possible applications in astronomy and space science.

“The American Naturalist” for May, 1871, contains an interesting article on “Flying Spiders,” by J. H. Emerton. The species noticed by him are, no doubt, allied to the gossamer of Europe, and the phenomenon occurs early in autumn on the Islands of the St.
