Productivity and morphological characteristics of buffel grass intercropped with butterfly pea under shade conditions

open access: yesBioscience Journal, 2017
Forage production in the Brazilian semiarid region can be enhanced by irrigation and shading to maximize water use. We evaluated the productivity and morphological characteristics of buffel grass (Cenchrus ciliaris) intercropped with butterfly pea ...

Photoswitching Conduction in Framework Materials

open access: yesAdvanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Charge Transport in Ternary Charge‐Transfer Solid Solution Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
This study deconvolutes the roles of indirect (superexchange) and direct electronic coupling on charge transport in single crystals of an organic charge‐transfer molecular semiconductor (OSC). This model system elegantly demonstrates that structural defects introduced by chemical dopants play a significant role in the electronic performance ...

Generalized Quadratic Linearization of Machine Models

open access: yesJournal of Control Science and Engineering, 2011
In the exact linearization of involutive nonlinear system models, the issue of singularity needs to be addressed in practical applications. The approximate linearization technique due to Krener, based on Taylor series expansion, apart from being ...

Block Copolymers: Emerging Building Blocks for Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This review addresses how block copolymer (BCP) physics and rheology have led to the widespread use of BCPs in advanced additive manufacturing techniques, with particular emphasis on the untapped potential of these nanostructured materials toward achieving multi‐scale architected materials with unique, programmable material properties.

Estimation of Inexact Multimixed Additive-Quadratic Mappings in Fuzzy Normed Spaces

open access: yesJournal of Mathematics
In the current study, we introduce a new model of multimixed additive-quadratic mapping and then show that the system of several mixed additive-quadratic equations defining a multimixed additive-quadratic mapping can be unified and presented as a single ...

Naimark-Sacker Bifurcations in Linearly Coupled Quadratic Maps

open access: yes, 2004
We report exact analytical expressions locating the $0\to1$, $1\to2$ and $2\to4$ bifurcation curves for a prototypical system of two linearly coupled quadratic maps.

Set simulations for quadratic systems

open access: yesIEEE Transactions on Automatic Control, 2003
In this paper, we study the problem of propagating in time a bounding set for the state of a class of nonlinear quadratic systems. The sequence of bounding sets is called the set simulation of the system, and conveys useful information about the stability and qualitative behavior of the possible time responses of the system.

Predicting Atomic Charges in MOFs by Topological Charge Equilibration

open access: yesAdvanced Functional Materials, EarlyView.
An atomic charge prediction method is presented that is able to accurately reproduce ab‐initio‐derived reference charges for a large number of metal–organic frameworks. Based on a topological charge equilibration scheme, static charges that fulfill overall neutrality are quickly generated.
