Emplacement and dewatering of the world's largest exposed sand injectite complex

Geochemistry, Geophysics, Geosystems, 2012
Sandstone injectites form by up or down‐section flow of a mobilized sand slurry through fractures in overlying rock. They act as reservoirs and high‐permeability conduits through lower permeability rock in hydrocarbon systems.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Regulating on-street parking [PDF]

Consider the choices available to a shopper driving to a city and trying to park downtown. One option, typical to many cities, is to follow the signposts to an off-street parking facility, which is often privately operated.

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Multiseptate Gallbladder in an Asymptomatic Child

Case Reports in Gastrointestinal Medicine, 2011
A one-year-old child being investigated for urinary tract infection was diagnosed with a multiseptate gallbladder. The patient remains asymptomatic, and investigations demonstrate no associated anomalies. Forty-three cases, including 13 cases in children

Subprime Lending: the Rotten Core of the Current Economic Crisis [PDF]

, 2008
Subprime lending has triggered a global financial crisis, but it remains misunderstood. Here are some basic facts, culled from an upcoming report on abandoned housing by the Partnership for the Public Good.

Single‐Cell Transcriptomics Reveals FLS2‐Dependent Hypoxia Signaling and ERF13‐Mediated Transcription During flg22‐Triggered Immunity

Advanced Science, EarlyView.
This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

Yeast heterochromatin stably silences only weak regulatory elements by altering burst duration

Cell Reports
Summary: Transcriptional silencing in Saccharomyces cerevisiae involves the generation of a chromatin state that stably represses transcription. Using multiple reporter assays, a diverse set of upstream activating sequence enhancers and core promoters ...
