Activated: Decentering activism in and with academia [PDF]

Companion Publication of the 2021 Conference on Computer Supported Cooperative Work and Social Computing, 2021
Who is an activist? With the advent of activism-related scholarship in HCI and CSCW, the current challenge involves thinking about what activism is, who an activist is, and the opportunities and limitations of activism. Recently, researchers in academia and industry, such as Timnit Gebru, demonstrate a commitment to stay activated for the structural ...

Activate or Not: Learning Customized Activation [PDF]

2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
We present a simple, effective, and general activation function we term ACON which learns to activate the neurons or not. Interestingly, we find Swish, the recent popular NAS-searched activation, can be interpreted as a smooth approximation to ReLU. Intuitively, in the same way, we approximate the more general Maxout family to our novel ACON family ...

To Activate or Not to Activate [PDF]

Circulation Research, 2013
In a recent study, Watanabe et al identify a novel enhancer in the fgf10 locus that is necessary and sufficient for expression in anterior second heart field. Their results suggest a competitive mechanism in which Isl1 and Nkx2-5 bind the enhancer to activate or repress this enhancer, respectively.

Scalable carbon dioxide electroreduction coupled to carbonylation chemistry

Nature Communications, 2017
Electroreduction of CO2 to CO is a potential valorisation pathway of carbon dioxide for fine chemicals production. Here, the authors show a user-friendly device that couples CO2 electroreduction with carbonylation chemistry for up to gram scale synthesis

Myosin IIa Promotes Antibody Responses by Regulating B Cell Activation, Acquisition of Antigen, and Proliferation

Cell Reports, 2018
Summary: B cell responses are regulated by antigen acquisition, processing, and presentation to helper T cells. These functions are thought to depend on contractile activity of non-muscle myosin IIa.

Transcriptional activators and activation mechanisms [PDF]

Protein & Cell, 2007
Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation. This article examines a few selected issues in understanding activator functions and activation mechanisms.

Cooperative redox activation for carbon dioxide conversion

Nature Communications, 2016
While CO2 can be converted to CO for further reactivity, typically this involves the generation of large amounts of waste. Here the authors report the conversion of CO2to CO, with the siloxane by-product being further used in a carbonylative Hiyama ...

Oscillation dynamics underlie functional switching of NF-κB for B-cell activation. [PDF]

, 2016
Transcription factor nuclear factor kappa B (NF-κB) shows cooperative switch-like activation followed by prolonged oscillatory nuclear translocation in response to extracellular stimuli.

Attempting to validate the over/under triage matrix at a level I trauma center. [PDF]

, 2017
The Optimal Resources Document (ORD) mandates trauma activation based on injury mechanism, physiologic and anatomic criteria and recommends using the over/undertriage matrix (Matrix) to evaluate the appropriateness of trauma team activation.

Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

Nature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.
