On integrating size and shape distributions into a spatio-temporal information entropy framework [PDF]

open access: yes, 2019
Understanding the structuration of spatio-temporal information is a common endeavour to many disciplines and application domains, e.g., geography, ecology, urban planning, epidemiology.

Improved Bounds on Fourier Entropy and Min-entropy [PDF]

open access: yesACM Transactions on Computation Theory, 2021
Given a Boolean function f:{ -1,1} ^{n}→ { -1,1, define the Fourier distribution to be the distribution on subsets of [n], where each S ⊆ [n] is sampled with probability f ˆ (S) 2 . The Fourier Entropy-influence (FEI) conjecture of Friedgut and Kalai [28] seeks to relate two fundamental ...

Comparative study on surface oxygenation and widening of carbon fibers made electrochemical electrodes

open access: yesAIP Advances, 2023
Polarity and surface area are two important factors in determining electrochemical performance and are here studied systematically using carbon fiber cloths (CFCs) as electrodes. The CFC polarity is enhanced by plasma treatment that creates polar groups,

Significant Improvement in Wear Resistance of CoCrFeNi High-Entropy Alloy via Boron Doping

open access: yesLubricants, 2023
CoCrFeNi high-entropy alloy (HEA) exhibits excellent mechanical properties but relatively poor wear resistance. In particular, when the load reaches a certain level and the deformation mechanism of the CoCrFeNi HEA changes, the formation of shear bands ...

Cryogenic strength improvement by utilizing room-temperature deformation twinning in a partially recrystallized VCrMnFeCoNi high-entropy alloy

open access: yesNature Communications, 2017
CrMnFeCoNi high entropy alloys have high fracture toughness at cryogenic temperatures due to deformation twinning but twinning is not active in this alloy at room temperature. Here authors optimize composition and thermomechanical treatments to introduce

Strain-rate sensitivity of high-entropy alloys and its significance in deformation

open access: yesMaterials Research Letters, 2019
Strain-rate dependence in face centered cubic high entropy alloys still remains controversial despite extensive efforts on this topic. Strain-rate sensitivity reflects underlying thermally-activated deformation and the controversy boils down to the ...

High-Temperature Mechanical Behavior of Cobalt-Free FeMnCrNi(Al) High-Entropy Alloys

open access: yesMetals, 2023
The high-temperature properties of new alloys need to be investigated to guide the hot working process. The temperature sensitivity of various microstructures of Fe45Mn15Cr15Ni25 and Fe35Mn15Cr15Ni25Al10 cobalt-free high-entropy alloys was investigated ...

Entropy Accumulation [PDF]

open access: yesCommunications in Mathematical Physics, 2020
AbstractWe ask the question whether entropy accumulates, in the sense that the operationally relevant total uncertainty about an n-partite system $$A = (A_1, \ldots A_n)$$ A = ( A 1 , … A n ) corresponds to the sum of the entropies of its parts $$A_i$$ A i .
