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

Advanced 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.

Influence over school discipline policy: Variation across levels of governance, school contexts, and time

Education Policy Analysis Archives, 2017
Little research explores the relative influence of various stakeholders on school discipline policy. Using data from the SASS and ordered logistic regression, this study explores such influence while assessing variation across schools types and changes ...

Expulsion of Implanon® [PDF]

Journal of Family Planning and Reproductive Health Care, 2007
A 24-year-old woman attended the family planning clinic in October 2005 reporting increasing discomfort over the site of her Implanon contraceptive implant. It had been inserted 6 months previously in the standard position in the left arm and apart from irregular slight bleeding she had had no problems with it until this point.

A galactic-scale origin for stellar clustering

, 2012
We recently presented a model for the cluster formation efficiency (CFE), i.e. the fraction of star formation occurring in bound stellar clusters. It utilizes the idea that the formation of stars and stellar clusters occurs across a continuous spectrum ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

Advanced Engineering Materials, EarlyView.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Levels of use of exclusionary discipline in U.S. public elementary schools: patterns over time and relations with chronic student absenteeism

Frontiers in Developmental Psychology
Exclusionary discipline (ExD)—including out-of-school suspensions and expulsions—remains widely used in U.S. public schools despite evidence of its ineffectiveness and disproportionate application.

A comprehensive set of simulations studying the influence of gas expulsion on star cluster evolution

, 2007
We have carried out a large set of N-body simulations studying the effect of residual-gas expulsion on the survival rate and final properties of star clusters.
