Foreign direct investments (FDI) are considered long-term and less sensitive to global shocks as they involve large amounts of capital investment that are costly to reverse. This study examines whether there was a reallocation of FDI flows from destination markets more affected by the pandemic, resulting in a pandemic arbitrage. Using bilateral FDI inflows data from January 2019 to December 2020, we show that FDI flows declined to destination markets that performed worse than source markets in COVID-19 infection rates, with the effect more evident in greenfield FDI. Our results also show that bilateral colonial ties and destination market COVID-19 policy stringency impact the pandemic arbitrage in FDI flows, especially for M&As. [ABSTRACT FROM AUTHOR]

Dietary flaxseed has been shown to have potent antiatherogenic effects in rabbits. The purpose of the present study was to investigate the antiatherogenic capacity of flaxseed in an animal model that more closely represents the human atherosclerotic condition, the LDL receptor-deficient mouse (LDLrKO), and to identify the cellular mechanisms for these effects. LDLrKO mice were administered a regular diet (RG), a 10% flaxseed-supplemented diet (FX), or an atherogenic diet containing 2% cholesterol alone (CH) or supplemented with 10% flaxseed (CF), 5% flaxseed (CF5), 1% flaxseed (CF1), or 5% coconut oil (CS) for 24 wk. LDLrKO mice fed a cholesterol-supplemented diet exhibited a rise in plasma cholesterol without a change in triglycerides and an increase in atherosclerotic plaque formation. The CS mice exhibited elevated levels of plasma cholesterol, triglycerides, and saturated fatty acids and an increase in plaque development. Supplementation of the cholesterol-enriched diet with 10% (wt/wt) ground flaxseed lowered plasma cholesterol and saturated fatty acids, increased plasma ALA, and inhibited plaque formation in the aorta and aortic sinus compared with mice fed a diet supplemented with only dietary cholesterol. The expression of proliferating cell nuclear antigen (PCNA) and the inflammatory markers IL-6, mac-3, and VCAM-1 was increased in aortic tissue from CH and CS mice. This expression was significantly reduced or normalized when flaxseed was included in the diet. Our results demonstrate that dietary flaxseed can inhibit atherosclerosis in the LDLrKO mouse through a reduction of circulating cholesterol levels and, at a cellular level, via antiproliferative and anti-inflammatory actions. linseed; nutrition; [alpha]-linolenic acid; cardiovascular disease; inflammation

This paper proposes a general quadrilateral-based framework for image segmentation, in which quadrilaterals are first constructed from an edge map, where neighboring quadrilaterals with similar features of interest are then merged together to form regions. Under the proposed framework, the quadrilaterals enable the elimination of local variations and unnecessary details for merging from which each segmented region is accurately and completely described by a set of quadrilaterals. To illustrate the effectiveness of the proposed framework, we derived an efficient and high-performance parameterless quadrilateral-based segmentation algorithm from the framework. The proposed algorithm shows that the regions obtained under the framework are segmented into multiple levels of quadrilaterals that accurately represent the regions without severely over or undersegmenting them. When evaluated objectively and subjectively, the proposed algorithm performs better than three other segmentation techniques, namely, seeded region growing, K-means clustering and constrained gravitational clustering, and offers an efficient description of the segmented objects conducive to content-based applications.

In this brief, a generalized topology of block shift networks (BSNs), named generalized block shift network (GBSN), is proposed for interconnection networks in clusters. The BSNs possess many desirable topological features, such as flexibility in node degree, small diameter and average distance, and easy VLSI implementation. However, the regular structure of each block in the BSN is not suitable for the networks in clusters that usually have arbitrary number of nodes. The proposed GBSN offers a balance between regularity and irregularity of the interconnection networks for clusters. We also analyze the embedding of the BSN into the GBSN, and discuss the versatility of the GBSN in terms of slowdown factors compared to the BSN. Index Terms--Block shift network (BSN), general block shift network (GBSN), routing, slowdown factor.
