JUNCTION RIEMANN PROBLEM FOR SHALLOW WATER EQUATIONS IN NETWORKS

TASK Quarterly, 2018
In this paper, the Riemann solution of an extended Riemann problem in channel networks is presented. The Riemann problem at a junction network is well defined in the literature. However, it is limited to symmetric networks.

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

Advanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

AN OCEAN DEPTH-CORRECTION METHOD FOR REDUCING MODEL ERRORS IN TSUNAMI TRAVEL TIME: APPLICATION TO THE 2010 CHILE AND 2011 TOHOKU TSUNAMIS [PDF]

Science of Tsunami Hazards, 2015
In this paper, we attempt to reduce the discrepancies between the modeled and observed tsunami arrival times. We treat the ocean as a homogenous fluid, ignoring stratification due to compressibility and variations of temperature and salinity.

Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

Advanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Step Soliton Generalized Solutions of the Shallow Water Equations

Journal of Applied Mathematics, 2012
Generalized solutions of the shallow water equations are obtained. One studies the particular case of a generalized soliton function passing by a variable bottom. We consider a case of discontinuity in bottom depth.

Generalized Z-Grid Model for Numerical Weather Prediction

Atmosphere, 2019
Z-grid finite volume models conserve all-scalar quantities as well as energy and potential enstrophy and yield better dispersion relations for shallow water equations than other finite volume models, such as C-grid and C-D grid models; however, they are ...

High‐Mobility Chalcogenophene‐Engineered Diketopyrrolopyrrole Mixed Ionic‐Electronic Conductors With Doping Tolerance for Low‐Power Organic Electrochemical Transistors

Advanced Materials, EarlyView.
Chalcogen substitution emerges as a powerful strategy for designing high‐performance OMIECs. In aliphatic–glycol side chain diketopyrrolopyrrole polymers, biselenophene incorporation promotes a planar, polarizable, and doping‐tolerant quinoidal framework, enabling PDPP‐4EG‐Se2 to combine high hole mobility, large µC*, enhanced operational stability ...

Dynamics of an idealized fluid model for investigating convective-scale data assimilation

Tellus: Series A, Dynamic Meteorology and Oceanography, 2017
An idealized fluid model of convective-scale numerical weather prediction, intended for use in inexpensive data assimilation experiments, is described here and its distinctive dynamics are investigated.

Breakdown of a shallow water equation [PDF]

Asian Journal of Mathematics, 1998
The author discusses the following two questions respecting the shallow water equations: 1. When does the shallow water flow breakdown? 2. How does the shallow water equation breakdown? To answer these questions he studies the 1D equation \(\partial v/\partial t+v(\partial v/\partial x)+\partial p/\partial x=0\) with ``pressure'' \(p(x)=(1/2)\int ...
