Coupling Scattering Characteristic Analysis of Dihedral Corner Reflectors in SAR Images
IEEE Access, 2018 The scattering mechanisms of dihedral corner reflectors have attracted great attention in the past decades. However, the scattering centers of dihedral corners are not discussed systematically.

The Role of Economic Analysis in Shaping Environmental Policy [PDF]
, 1991 The experience of the US in using economic analysis to develop environmental policy is examined. Regulatory actions needed to create environmental benefits often impose substantial costs--both direct costs and indirect effects on other social goals--so ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Heme Oxygenase Activity Correlates with Serum Indices of Iron Homeostasis in Healthy Nonsmokers
Biomarker Insights, 2016 Heme oxygenase (HO) catalyzes the breakdown of heme to carbon monoxide, iron, and biliverdin. While the use of genetically altered animal models in investigation has established distinct associations between HO activity and systemic iron availability ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Novel Efficient WLP-Based BOR FDTD Method With Explicit Treating Ideology
IEEE Access, 2019 In this paper, we proposed a novel efficient weighted Laguerre polynomial (WLP)-based finite-difference time-domain (FDTD) method with explicit treating ideology, which is extremely useful for problems with very fine structures in the body of revolution (
