The Futures Premium and Rice Market Efficiency in Prewar Japan [PDF]

open access: yesarXiv, 2014
This paper studies the interrelation between spot and futures prices in the two major rice markets in prewar Japan from the perspective of market efficiency. Applying a non-Bayesian time-varying model approach to the fundamental equation for spot returns and the futures premium, we detect when efficiency reductions in the two major rice markets ...

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals

The Colonial Origins of Comparative Development: An Empirical Investigation

open access: yes, 2000
We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

open access: yesAdvanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.
