Using cell‐free RNA to identify B‐ and T‐cell clonality for diagnosis and monitoring of B‐ and T‐cell neoplasms

FEBS Open Bio, EarlyView.
Using peripheral blood for determining B‐cell or T‐cell clonality is more reliable when we use cell‐free RNA (cfRNA) because cells release blood significantly more RNA than DNA. Next‐generation sequencing (NGS) of cfRNA allows us to evaluate fragment cfRNA and evaluate clonality reliably without the need for prior determination of the specific dominant

L-band Amplifier Placement in C+L-band Elastic Optical Networks

Asia Communications and Photonics Conference 2021, 2021
To extend a fiber-optic transmission system from traditional C band to C+L band, it is necessary to place L-band optical amplifiers so as to amplify L-band optical signals. We consider three L-band amplifier placement strategies in the context of a C+L-band elastic optical network (EON).

$L$ -Band Ocean Surface Roughness

IEEE Transactions on Geoscience and Remote Sensing, 2020
Surface wave spectral properties of centimeter to decameter (cmDm) wavelengths are of great interest to microwave remote sensing of the ocean. They are obviously different from the high-frequency extension of the wind-wave spectrum models developed for ocean science and engineering applications, which focus on the longer waves in the energetic peak ...

Present and Future of L-Band Radiometry

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
After almost 9 years in orbit L band satellite radiometry has demonstrated its impacts and values for a wide range of science and applications. In some cases it has demonstrated its uniqueness for assessing key environmental variables and in many others its high impact.

Vegetation Effects on Covariations of L-Band Radiometer and C-Band/L-Band Radar Observations

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
NASA's Soil Moisture Active-Passive (SMAP) mission aims at disaggregating L-band radiometer (36 km) with L-band radar (1–3 km) observations to obtain an intermediate resolution soil moisture product (1–9 km). Since SMAP's radar stopped operations in July 2015, a substitution with ESA's Sentinel 1 C-band radar is underway.

Airborne L-band RFI observations in the smapvex08 campaign with the L-band interference suppressing radiometer

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Radio Frequency Interference (RFI) is a major concern for microwave radiometry. In September-October 2008, an airborne campaign for observing L-band RFI was conducted and included approximately fifty hours of flight time. The campaign included test flights in Grand Junction, Colorado, observations over soil moisture ground truth sites in Iowa and ...

Hybrid integrated L-band transmitter

IEEE Transactions on Electron Devices, 1968
Microstrip circuit techniques are applied to the development of a small, light-weight, ruggedized, L-band 200-mW oscillator. Performance data of the oscillator are given and two applications, a radiosonde and a projectile telemetry transmitter, are described.

The L-band SAR pre-development

SPIE Proceedings, 2004
This paper outlines the development status of an L-band synthetic aperture radar (SAR) antenna demonstrator undertaken by an industrial consortium under contract to the European Space Agency (ESA). Its aim is to verify the technology and the satisfactory performance of the SAR active antenna in advance of the development of the full L-band SAR ...
