Breaking point: Identifying the factors that predict suspension from school

open access: yesBritish Educational Research Journal, EarlyView.
Abstract School suspensions are associated with adverse educational and psychosocial outcomes, yet little is known about how structural disadvantage, relational factors, health behaviours, well‐being indicators and school‐level factors jointly predict suspension risk in England.

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method

open access: yesTongxin xuebao, 2012
For arbitrary code lengths of the form PL(P≥3L<sup>2</sup>/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

Algebra-Assisted Construction of Quasi-Cyclic LDPC Codes for 5G New Radio

open access: yesIEEE Access, 2018
Quasi-cyclic LDPC (QC-LDPC) codes have been accepted as the standard codes of 5G enhanced mobile broadband data channel. These standard codes are designed to support multiple lifting sizes and possess rate-compatible property, which can help adapt ...

Harmonized Multifaceted Zinc Deposition Enabled by Amine‐Functionalized Carbon Quantum Dots for Dendrite‐Free Zinc Anodes Under Ultrahigh Current Densities

open access: yesCarbon Energy, EarlyView.
A novel multifaceted Zn2+ deposition along the native crystal planes of Zn foil has been developed using NH2‐CDs electrolyte additives. This approach overcomes the inability of the conventional (002)‐facet deposition strategy to suppress Zn dendrites at high current densities, achieving dendrite‐free Zn anodes at an ultrahigh current density of 100 mA ...

Fatigue crack growth characteristics of Fe and Ni under cyclic loading using a quasi-continuum method

open access: yesBeilstein Journal of Nanotechnology, 2018
A quasi-continuum (QC) method based on the embedded atom method (EAM) potential was employed to investigate the fatigue crack growth and expansion characteristics of single-crystal Fe and Ni under cyclic loading modes I and II.

Multiscale Analysis of Amine‐Containing CO2 Capture Membrane via Dissipative Particle Dynamics Simulations Using Ab Initio Elongation Method‐Based Parameters

open access: yesCarbon Energy, EarlyView.
Elongation (ELG) method for calculating the electronic structures of aperiodic polymers was combined with dissipative particle dynamics (DPD) simulation to perform more reliable simulations using quantum chemistry (QC)‐based parameters. The method was employed to analyze phase separation in an amine‐containing CO2 capture membrane, and the results ...

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

open access: yesChemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

On the Girth of Tanner (3, 13) Quasi-Cyclic LDPC Codes

open access: yesIEEE Access, 2019
Girth is an important structural property of low-density parity-check (LDPC) codes. Motivated by the works on the girth of Tanner (3, 5), (3, 7), (3, 11), and (5, 7) quasi-cyclic (QC) LDPC codes, we, in this paper, study the girth of Tanner (3, 13) QC ...

Numerical Analysis and Optimization of a Continuous‐Flow pH‐TRC for Steady‐State Low‐Grade Waste Heat Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.

Type-II QC-LDPC Codes From Multiplicative Subgroup of Prime Field

open access: yesIEEE Access, 2020
A quasi-cyclic (QC) low-density parity-check (LDPC) code is called type-II, if the maximum weight over all circulants appearing in the parity-check matrix has the value of two. On the basis of multiplicative subgroup analysis for the prime field, a novel
