Lost in aggregation? On the importance of local food price data for food poverty estimates

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Genome‐Guided Discovery of Antimalarial 4‐Amino‐2,4‐Pentadienoate‐Containing Cyclolipodepsipeptides

open access: yesAngewandte Chemie International Edition, EarlyView.
Halogenated and glycosylated 4‐amino‐2,4‐pentadienoate‐containing cyclolipodepsipeptides (APD‐CLDs) exhibit potent antiplasmodial activity (IC50 = 25–161 nM) against drug‐sensitive and resistant Plasmodium falciparum strains. ABSTRACT 4‐Amino‐2,4‐pentadienoate‐containing cyclolipodepsipeptides (APD‐CLDs) represent a structurally distinctive family of ...

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Universal Entanglement and an Information‐Complete Quantum Theory

open access: yesAdvanced Physics Research, EarlyView.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

Toroidal‐Dipole‐Driven Polarization‐Selective Quasi‐BICs Enabling Wide‐Angle Near‐Field Image Display in Dielectric Metasurfaces

open access: yesAdvanced Physics Research, EarlyView.
This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.
