Exact Periodic Solutions for the Forced Oscillations of a Symmetric Nonlinear System with “Set-up Springs” [PDF]
This paper presents the exact periodic solutions for the forced oscillation of a symmetric nonlinear system with “set-up springs”. There exist many kinds of solutions, the “harmonic” solution, the subharmonic solution of odd order and the subharmonic ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Reimagining Inclusivity in Literacy Education for African Immigrant Adolescents
ABSTRACT This study explored how an Afrocentric literacy workshop can reimagine inclusivity in literacy education for African immigrant adolescents. Drawing on Afrocentricity and Transnational Identity Theory, I facilitated a 10‐week virtual literacy workshop with six African immigrant high school students from Nigeria.

Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

Some notes on an approximate solution for the free oscillation characteristics of non-linear systems typified by ẍ +F(x, ẋ) = 0 [PDF]
A modified form of the approximate method developed by Kryloff and Bogoliuboff is derived and applied to particular cases with a large frequency dependence on amplitude.

Reasons, Mistakes, and Excuses
Drawing on the theory of practical reasons, John Gardner has offered a seminal account of excuses in criminal law. His proposal is that an excuse asserts that the defendant acted for what she justifiably believed to be sufficient reason for her to perform the offending act although she had no such reason.

ABSTRACT Vocabulary knowledge is foundational to educational success, but significant gaps exist between students with reading disabilities or those from disadvantaged backgrounds and their peers. These gaps have cascading effects, as children with lower vocabulary knowledge are less likely to acquire new words through independent reading and are less ...
