NET‐DNA Activates the ANXA2/TMEM215/BiP Axis to Promote Mitophagy‐Mediated Anoikis Resistance in Endometriosis

open access: yesAdvanced Science, EarlyView.
NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...

Large Amount of Off-Axis Machining Ellipsoidal Reflector

Applied Mechanics and Materials, 2014
The article introduces the off-axis ellipsoidal mirror processing and testing, and uses AutoCAD software to calculate the maximum aspheric mirrors degrees. After processing the off-axis ellipsoidal reflector inclination error of 1.55arcsec, root mean square roughness ((RMS) of 3.21nn, focal length error is less than 1mm, and the surface accuracy can ...

A Radiant-Energy Heater Using an Ellipsoidal Reflector

IBM Journal of Research and Development, 1957
The effectiveness of a radiant-energy heater employing a hemi-ellipsoidal aluminum reflector and an incandescent lamp as radiation source is illustrated by application to the zone-melting of germanium. The factors affecting the design and performance of this heater are discussed.

A laser-induced fluorescence biosensor by using ellipsoidal reflector

Optics & Laser Technology, 2007
Abstract A new and compact fluorescence biosensor is constructed. The distinguished feature of this setup is the use of an ellipsoidal reflector as an optical collector of the fluorescence light. A traditional collecting lens with numerical aperture of 0.5 can only collect a few percent of the available signal, while the incorporation of the ...

Realistic implementation of ellipsoidal reflector antennas to produce near‐field focused patterns

Radio Science, 2011
The radiation characteristics of ellipsoidal reflector antennas in the near zone of antenna aperture are investigated using Physical Optics (PO) approximations. This antenna has potential applications in the near‐field communications because its radiation focuses in the near zone.

A Bifocal Ellipsoidal Gregorian Reflector System for THz Imaging Applications

IEEE Transactions on Antennas and Propagation, 2012
Current terahertz imagers rely on reflector systems for the beam quality and imaging speed because the cross-range span that the system can cover is limited by the beam aberrations when the antenna scans. We present the design of a Bifocal reflector system that can rapidly scan a terahertz beam for standoff imaging applications while increasing the ...

Study on a THz image scanning system with ellipsoidal reflector

2015 8th UK, Europe, China Millimeter Waves and THz Technology Workshop (UCMMT), 2015
This paper presents our study on a reflector system for mechanically scanned imager working at 220 GHz. An ellipsoidal reflector is utilized to replace a paraboloidal reflector to achieve another focus on the target plane under the consideration of better performance in the near field imaging.

Ellipsoidal reflector design of the LED vehicle projector type headlamp

SPIE Proceedings, 2016
In this study, the design of the projector type headlamp using LEDs with different structure parameters is proposed. The ellipsoidal reflector with different major and minor axis would contribute different aperture and focal lengths of the ellipsoidal reflector, and then collimate the light to the converging lens.
