Do bold shakeups of the learning-teaching agreement work? A commognitive perspective on a LUMOS low lecture innovation [PDF]

, 2014
Mathematics undergraduates, and their lecturers, often describe the transition into university mathematics as a process of enculturation into new mathematical practices and new ways of constructing and conveying mathematical meaning (Nardi, 1996 ...

Social valuation of biodiversity relative to other types of assets at risk in wildfire

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Environmental crises, such as wildfires, can cause major losses of human life, infrastructure, biodiversity, and cultural values. In many such situations, incident controllers must make fateful choices about what to protect—and hence what to abandon.

Expression of Fused in sarcoma mutations in mice recapitulates the neuropathology of FUS proteinopathies and provides insight into disease pathogenesis

Molecular Neurodegeneration, 2012
Background Mutations in the gene encoding the RNA-binding protein fused in sarcoma (FUS) can cause familial and sporadic amyotrophic lateral sclerosis (ALS) and rarely frontotemproal dementia (FTD).

一种新的光CDMA系统地址码的构造与分析

Guangtongxin yanjiu, 2007
基于对LSOOC码的修正,提出了一种光谱幅度编码光码分多址（SAC-OCDMA）地址码的设计方案。分析了码字特性,与Hardmard、MQC、MFH、BIBD（m=2）码做了比较,设计了可调谐光纤布拉格光栅（FBG）编解码器,阐述了编解码原理。分析结果表明,该码字容量大,编解码方法简单,在光源和信道理想条件下可以消除多址干扰。

Establishing a Spectral Optical CDMA System Involving the Use of Two Mutually Orthogonal States of Polarizations Using 1-D Two-Distinct Codes With Two-Code Keying

IEEE Access
We propose 1-D Two-Distinct codes with two-code keying (TCK) using two mutually orthogonal states of polarization (SOP) in spectral components as a new code family for spectral amplitude coding (SAC) in optical code division multiple access (OCDMA ...
