Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform
We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.
