Note sur l’adverbe temporel już et ses correspondants français

open access: yesCognitive Studies | Études cognitives, 2015
A remark concerning the temporal adverb już and its French equivalents Generally speaking, this contrastive study of the Polish temporal adverb już and the French déjà is based around the idea that już and déjà have an invariant meaning but it is also ...

Simulation‐Based Assessment of Second‐Order Residual Stress Fields on the Fatigue Performance of Silicon‐Strengthened Ferritic Ductile Irons

open access: yesAdvanced Engineering Materials, EarlyView.
This work presents a simulation‐based framework based on representative volume elements (RVEs) that explicitly incorporates process‐induced second‐order residual stresses into the fatigue strength assessment of ductile cast iron (DCI). For the first time, this approach enables a direct evaluation of the influence of second‐order residual stress fields ...

Feeling Pressure to Be a Perfect Mother Relates to Parental Burnout and Career Ambitions

open access: yesFrontiers in Psychology, 2018
Background and aims: Intensive mothering norms prescribe women to be perfect mothers. Recent research has shown that women’s experiences of pressure toward perfect parenting are related to higher levels of guilt and stress.

On‐Demand Activation of Thin Alginate Shell Encapsulated Volatile Liquid for Untethered Pneumatic Soft Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

Selective dual-band metamaterial perfect absorber for infrared stealth technology

open access: yesScientific Reports, 2017
We propose a dual-band metamaterial perfect absorber with a metal–insulator–metal structure (MIM) for use in infrared (IR) stealth technology. We designed the MIM structure to have surface plasmon polariton (SPP) and magnetic polariton (MP) resonance ...

Theory of metasurface based perfect absorbers [PDF]

open access: yes, 2017
Based on an analytic approach, we present a theoretical review on the absorption, scattering, and extinction of both dipole scatterers and regular arrays composed of such scatterers i.e. metasurfaces.

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

The Perfect in (Brazilian) Portuguese: A Functional Discourse Grammar View

open access: yesOpen Linguistics, 2018
In most Germanic and Romance languages the present perfect has developed from a resultative meaning via an anterior into absolute past. In Functional Discourse Grammar terms this corresponds to the grammaticalization of a phasal aspectual operator at the

Perfect necklaces

open access: yesAdvances in Applied Mathematics, 2016
We introduce a variant of de Bruijn words that we call perfect necklaces. Fix a finite alphabet. Recall that a word is a finite sequence of symbols in the alphabet and a circular word, or necklace, is the equivalence class of a word under rotations. For positive integers k and n, we call a necklace (k,n)-perfect if each word of length k occurs exactly ...
