INTENSIVE THRESHING MECHANISM IMPROVEMENT
Advanced Engineering Research, 2012 It is shown that the intensive threshing mechanism, containing the drum with smooth rasp bars an d the concave with a convex inlet and canting bars with flanges (_/ - shaped bars) without rods throughout the remaining exte nsion, may become more ...

Discrete Mathematics, 1991 A sequence \(a_ 0,\dots,a_ n\) is said to be log concave if \(a_{i- 1}a_{i+1}\leq a^ 2_ i\) for \(i=1,\dots,n-1\). In this note a log concave sequence is assumed to consist of positive real numbers. The main result of the authors shows how a log concave sequence generates a log supermodular function on the lattice \(\{(i,j)\mid\;0\leq i,j\leq n ...

Advanced Materials, EarlyView.The miscibility of foreign elements in rutile‐type IrO2 and SnO2 is greatly enhanced under high Laplace pressure, where their crystal size is reduced to the nanoscale. This enhancement leads to the successful synthesis of DSA‐composition solid‐solution nanocatalysts with notable durability during the acidic OER in water electrolysis.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...
