Formation of Box Canyon, Idaho, by megaflood: implications for seepage erosion on Earth and Mars [PDF]

open access: yes, 2008
Amphitheater- headed canyons have been used as diagnostic indicators of erosion by groundwater seepage, which has important implications for landscape evolution on Earth and astrobiology on Mars.

Alkali Ion‐Incorporated HfO2 Dielectrics for Reconfigurable Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
This work presents an indium gallium zinc oxide (IGZO) transistor with an alkali cation‐integrated hafnium dioxide (HfO2) dielectric exhibiting synaptic behavior via ion retention. The solution‐based film fabrication strategy overcomes the limitations of atomic layer deposition (ALD) and precursor coating, enabling the control of synaptic retention ...

Time-varying drainage basin development and erosion on volcanic edifices [PDF]

open access: yesEarth Surface Dynamics
The erosional state of a landscape is often assessed through a series of metrics that quantify the morphology of drainage basins and divides. Such metrics have been well explored in tectonically active environments to evaluate the role of different ...

Management of deep space infections of the neck [PDF]

open access: yes, 2018
Infections of the deep neck spaces often present a clinical challenge for the ENT surgeon. Management of these complex suppurations of the neck requires in fact a multidisciplinary approach due to possible complications like mediastinitis, septic shock ...

Dual‐Interface Engineering of the Source Electrode to Overcome the Intrinsic Injection‐Leakage Trade‐Off in Organic Schottky Barrier Transistors

open access: yesAdvanced Functional Materials, EarlyView.
A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.

Geomorphic signatures of active tectonics in the Poonch basin, Northwestern Himalaya, India

open access: yesResults in Earth Sciences
The Poonch Basin, situated in the tectonically active northwestern Himalaya, represents an ideal natural laboratory to evaluate geomorphic responses to ongoing crustal deformation.

Implementation of the hydraulic modelling of urban drainage in the northeast sector, Tunja, Boyacá

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2020
Historically, in the city of Tunja there has been a phenomenon of occupation of the natural channels of rainwater, altering the hydrology of the natural basins.

Intermixing‐Driven Growth of Highly Oriented Indium Phosphide on Black Phosphorus

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates controlled intermixing and compound formation at the In/black phosphorus (BP) interface, leading to highly oriented InP formation. Comprehensive structural and electrical analyses reveal tunable bandgap behavior governed by competing BP thinning and charge‐transfer effects, underscoring the critical role of interfacial compound ...

Parametric survey of longitudinal prominence oscillation simulations [PDF]

open access: yes, 2013
It is found that both microflare-sized impulsive heating at one leg of the loop and a suddenly imposed velocity perturbation can propel the prominence to oscillate along the magnetic dip.
