THE INFLUENCE OF APEX ANGLE ON MIXED CONVECTION IN A POROUS SECTOR CHANNEL

open access: yesDiyala Journal of Engineering Sciences, 2011
The influence of apex angle on mixed convection in a horizontal porous sector channel is investigated. The analysis is performed by considering fully- developed hydrodynamically and thermally flow.

T-Channel Field Effect Transistor with Three Input Terminals (Ti-TcFET)

open access: yesMicromachines, 2020
In this paper, a novel T-channel field effect transistor with three input terminals (Ti-TcFET) is proposed. The channel of a Ti-TcFET consists of horizontal and vertical sections.

Global Engagement and Returns Volatility [PDF]

open access: yes, 2015
This paper finds that a greater reliance on foreign market sales increases the volatility of firms’ stock returns, using high-frequency data for publicly listed Japanese manufacturing firms over the period 2000–10. The two margins of global engagement we

Slug Initiation Evaluation in Long Horizontal Channels Experimentally

open access: yes, 2014
In this paper, the effects of gas and liquid superficial inlet velocities and for the first time the effect of liquid holdup on slug initiation position are studied experimentally. Empirical correlations are also presented based on the obtained results.

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Cycloid flows induced by the Large horizontal coherent structures in the vegetated compound channel

open access: yesE3S Web of Conferences, 2018
Vegetation in general and mangrove, in particular, plays a significant role in the protection of the coastal and estuarine regions from erosion. In particular, estuarine mangrove forests can effciently reduce the impact of a strong along-bank flow during

Advanced Quantizer Designs for FDD-Based FD-MIMO Systems Using Uniform Planar Arrays

open access: yes, 2018
Massive multiple-input multiple-output (MIMO) systems, which utilize a large number of antennas at the base station, are expected to enhance network throughput by enabling improved multiuser MIMO techniques.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

open access: yesFEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Interface-resolved direct numerical simulation of the erosion of a sediment bed sheared by laminar channel flow

open access: yes, 2014
A numerical method based upon the immersed boundary technique for the fluid-solid coupling and on a soft-sphere approach for solid-solid contact is used to perform direct numerical simulation of the flow-induced motion of a thick bed of spherical ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
