Twist, a key regulator of epithelial-mesenchymal transition (EMT), plays an important role in the development of a tumorigenic phenotype. Energy metabolism reprogramming (EMR), a newly discovered hallmark of cancer cells, potentiates cancer cell proliferation, survival, and invasion. Currently little is known about the effects of Twist on tumor EMR. In this study, we found that glucose consumpt...

Stacking procedures with the objective of improvement of signal to noise ratio were in use before the introduction of Common reflection point stacking introduced by Mayne in 1962. But, these techniques were problematic, at times, because they used reflections from a portion of reflectors that were too large. Hence, stacking tends to obscure the very detail of reflector which is being sought. So...

In this note we begin the development of two types of Impulse Radiating Antenna (IRA). o These two designs include a 23 cm diameter reflector IR4, with an F/D of0.38, and a solid dielectric-lens IIU4, or dielectric-immersed lens IIU. This latter design is a Transverse Electromagnetic (TEM) horn immersed in a dielectric, with a prolate spheroidal lens interface to air. The reflector IR4 consists...

-A polarimetric radar navigation system makes use o f polarization rotating twist-grid retroreflectors in order to navigate a confined waterway, even in inclement weather or after dark. Despite the polarization diversity offered by such a radar target, depolarization allows significant cross-polar clutter to obscure the reflector return. A novel modular neural network solution integrates an ada...

With the deployment of advanced multicast routing protocols and transport protocols for real-time data, multicast services on the Internet experience renaissance. Together with the global improvements in the underlying network infrastructure, this opens possibilities for a wide range of exciting multimedia applications. However, many Internet hosts are not connected to MBone, the Internet multi...

All of NASA’s Deep Space Network (DSN) 70-m reflectors were measured using a Leica TDM-5000 theodolite. The main-reflector surface was measured at five elevation angles so that a gravity deformation model could be derived that described the main-reflector distortions over the entire range of elevation angles. The article describes the measurement equipment and accuracy and the results derived f...

Antenna reflector losses play an important role in the calibration budget for a microwave radiometer. If the losses are small, they are difficult to measure by traditional means. However, they can be assessed directly by radiometric means using the sky brightness temperature as incident radiation. This paper describes how such measurements are carried out as well as a suitable experimental setu...

A low-threshold-current distributed reflector laser consisting of phase-shifted distributed feedback (DFB) grating and quantumwire distributed Bragg reflector (DBR) sections was realized. The device with a DFB length of 150μm, a DBR length of 240μm and a stripe width of 1.5μm achieved a threshold current as low as 1.2mA and a differential quantum efficiency of 13% from the front facet under RT-...
