On the Dynamics of an Oil Price Model [PDF]
ISRN Applied Mathematics, 2014 We address the dynamic of an energy price model in a more general approach; to our knowledge, in previous works, different conditions are imposed on the energy price function at a particular value in order to characterize stability and unstability for real or complex eigenvalues.

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal
Advanced Functional Materials, EarlyView.Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Advanced Functional Materials, EarlyView.Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

, 1983 The price of oil has confounded so many commentators so often in the past that there are few people close to the industry who are willing to make any public predictions. Although conscious of rushing in where more prudent economists have feared to tread I would nevertheless offer the judgement that the world market price of crude oil might be expected ...
