Advanced Functional Materials, EarlyView.Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device
Advanced Functional Materials, EarlyView.In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Parsimony and omitted factors: the airline model and the Census X-11 assumptions [PDF]
, 1985 El tipo de modelo Arima para el que el metodo de ajuste estacional X-11 es adecuado se ha identificado como (1-L)(1-L12)Xt=G(L)at, (CX), en donde G(L) es de orden 26. En este documento se aproxima el modelo CX mediante un modelo Arima (1,1,2)(0,1,1), con

Advanced Functional Materials, EarlyView.Mg‐based thermoelectrics are among the most promising candidates for power generation applications but their performance is compromised by Mg loss at device operation temperatures due to the higher chemical potential of Mg (μMg${\mu}_{\mathrm{Mg}}$) inside the material compared to the environment.
