A class of CTRWs: Compound fractional Poisson processes

open access: yes
This chapter is an attempt to present a mathematical theory of compound fractional Poisson processes. The chapter begins with the characterization of a well-known L\'evy process: The compound Poisson process.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
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

Physical Properties of Transition Metal Hydride Superconductors Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) by First‐Principles Calculations

open access: yesAdvanced Physics Research, EarlyView.
The electronic band structure determines all the charge transport properties of crystalline solids. It also controls the optical response of the material. Bonding characters are strongly influenced by the band structure. The band structures of Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) compounds shown above confirm their metallic nature.

Mechanistic Digital Model for Real‐Time Monitoring and Optimization of Adenovirus Production

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Adenoviral vectors are a critical vaccine platform, with billions of vaccine doses administered during the COVID‐19 pandemic. In addition, they are promising therapeutics for cancer treatment. To advance their manufacturing, real‐time monitoring of adenovirus production is essential for process optimization, yield improvement, and product ...
