Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

open access: yesAdvanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.

Strength and behavior of steel fibre lightweight concrete wall panel under one way in plane action / Norfariza Ismail [PDF]

open access: yes, 2014
Nowadays, with the rapid development of high rise building, larger size and span concrete structures are required. Wall panel is a structural element that considered as a vertical load bearing member that carries weight from the roof to the ground floor ...

Ferroelectric Devices for In‐Memory and In‐Sensor Computing

open access: yesAdvanced Science, EarlyView.
Inspired by biological systems, in‐memory and in‐sensor computing overcome von Neumann bottlenecks. Ferroelectric devices can mimic synaptic functions and sense stimuli like light or force, therefore are ideal for these paradigms. This review introduces the ferroelectric devices applied for in‐memory and in‐sensor computing, covering their structures ...

Synthetic fibres and steel fibres in concrete with regard to bond strength and toughness [PDF]

open access: yes, 2009
The ability of fibre reinforced concrete composites to absorb energy has long been recognised as one of the most important benefits of the incorporation of fibres into plain concrete” (Golpalaratham and Gettu 1995).

Functional Disorder at the Neural Interface: How Disordered Nanostructures Promote Proper Growth and Differentiation in In Vitro Neural Cultures

open access: yesAdvanced Science, EarlyView.
This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

open access: yesAdvanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

ANALYSIS AND EVALUATION OF EXPERIMENTAL METHODS FOR DETERMINING THE STRENGTH OF CONCRETE

open access: yesBulletin of Kazakh Leading Academy of Architecture and Construction
The study presents an overview of several experimental techniques used to determine the strength and bearing capacity of concrete. During the research, special attention was paid to how the quality of the mix and curing conditions influence the reliability of the results. The experiments were carried out on cube, prism, and cylinder specimens that were

Determination of Compressive Strength of Concrete by Statistical Learning Algorithms

open access: yesEngineering Journal, 2013
This article adopts three statistical learning algorithms: support vector machine (SVM), lease square support vector machine (LSSVM), and relevance vector machine (RVM), for predicting compressive strength (f c ) of concrete. Fly ash replacement ratio (FA), silica fume replacement ratio (SF), total cementitious material (TCM), fine aggregate (ssa ...
