Bias and blindsight: A reply to Michel and Lau (2021).

Ian Phillips

Psychol Rev 2021 Apr;128(3):592-595

William H. Miller III Department of Philosophy, Johns Hopkins University.

According to the textbooks, blindsight is a neuropsychological condition characterized by preserved capacities for voluntary visual discrimination unaccompanied by visual awareness. So construed, blindsight precipitated a revolution in theorizing consciousness. In Phillips (Psychological Review, 2021), I argued that the textbooks are wrong and the revolution ill-founded.

Connecting the Dots: a cluster-randomized clinical trial integrating standardized autism spectrum disorders screening, high-quality treatment, and long-term outcomes.

Trials 2021 May 2;22(1):319. Epub 2021 May 2.

AJ Drexel Autism Institute, Drexel University, 3020 Market Street, Philadelphia, PA, 19104, USA.

Background: Autism spectrum disorder (ASD) affects one in 54 children in the United States of America, and supporting people with ASD across the lifespan presents challenges that impact individuals, families, and communities and can be quite costly. The American Academy of Pediatrics has issued recommendations for routine ASD screening at 18 and 24 months, but some research suggests that few pediatricians perform high-fidelity, standardized screening universally. Furthermore, the United States Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against universal ASD screening. Read More

An Efficient Anomaly Recognition Framework Using an Attention Residual LSTM in Surveillance Videos.

Sensors (Basel) 2021 Apr 16;21(8). Epub 2021 Apr 16.

Sejong University, Seoul 143-747, Korea.

Video anomaly recognition in smart cities is an important computer vision task that plays a vital role in smart surveillance and public safety but is challenging due to its diverse, complex, and infrequent occurrence in real-time surveillance environments. Various deep learning models use significant amounts of training data without generalization abilities and with huge time complexity. To overcome these problems, in the current work, we present an efficient light-weight convolutional neural network (CNN)-based anomaly recognition framework that is functional in a surveillance environment with reduced time complexity.

Microfluidic particle accumulation for visual quantitation of copper ions.

Mikrochim Acta 2021 Apr 27;188(5):176. Epub 2021 Apr 27.

Department of Biomedical Engineering, City University of Hong Kong, Hong Kong, Hong Kong.

A portable biosensor has been developed based on microfluidic particle accumulation for visual quantification of copper ions. A copper-dependent DNAzyme is used to connect magnetic microparticles (MMPs) and polystyrene microparticles (PMPs), forming "MMPs-DNAzyme-PMPs." When copper ions are present, the DNAzyme is cleaved, allowing free PMPs to be released from the MMPs-DNAzyme-PMP complex. Read More

Surface-Radical Mobility Test by Self-Sorted Recombination: Symmetrical Product upon Recombination (SPR).

J Phys Chem B 2021 Apr 15;125(16):4212-4220. Epub 2021 Apr 15.

Department of Chemistry, Brooklyn College, 2900 Bedford Avenue, Brooklyn, New York 11210, United States.

We describe here a study of the mobility of the alkoxy radical on a surface by detection of its recombination product. A novel method called symmetrical product recombination (SRP) uses an unsymmetrical peroxide that upon sensitized homolysis recombines to a symmetrical product [R'OOR → R'O↑ + OR → ROOR]. This allows for self-sorting of the radical to enhance the recombination path to a symmetrical product, which has been used to deduce surface migratory aptitude. Read More

Mechanism Across Scales: A Holistic Modeling Framework Integrating Laboratory and Field Studies for Microbial Ecology.

Front Microbiol 2021 24;12:642422. Epub 2021 Mar 24.

Division of Environmental Genomics and Systems Biology, Lawrence Berkeley National Laboratory, Berkeley, CA, United States.

Over the last century, leaps in technology for imaging, sampling, detection, high-throughput sequencing, and -omics analyses have revolutionized microbial ecology to enable rapid acquisition of extensive datasets for microbial communities across the ever-increasing temporal and spatial scales. The present challenge is capitalizing on our enhanced abilities of observation and integrating diverse data types from different scales, resolutions, and disciplines to reach a causal and mechanistic understanding of how microbial communities transform and respond to perturbations in the environment. This type of causal and mechanistic understanding will make predictions of microbial community behavior more robust and actionable in addressing microbially mediated global problems. Read More
