Power independent degradation of high power GaAlAs lasers with nonabsorbing-mirrors

12th IEEE International Conference on Semiconductor Laser, 1990
The reliability of high-power single-mode GaAlAs lasers with nonabsorbing mirrors (NAMs) was investigated in detail. The lasers were tested at various output powers and temperatures. The aging test was performed under constant power in order to examine the output power dependence.

Intra-Follicular Proliferation Rate Is a Powerful Independent Prognosticator in Follicular Lymphoma.

Blood, 2004
Abstract Several prognostic scores are used to predict the outcome of patients with follicular lymphoma (FL). Histologic grading is widely used, but poorly reproducible. Scoring systems such as the (FL)IPI consist of surrogate clinical markers that probably reflect underlying biological phenomena.

Tumor response heterogeneity, a powerful independent predictor of treatment outcome in advanced lung adenocarcinoma.

Journal of Clinical Oncology, 2022
e21146 Background: Tumor response heterogeneity (TRH) to treatment is common across different foci within the same cancer patient. However, the effect of heterogeneity on clinical outcome remains unclear. Here, we developed a quantitative assessment of TRH and explored the correlation of TRH with the clinical outcome.

Enhanced Dynamic Range Power Independent Doppler Frequency Estimation System

IEEE Sensors Journal, 2018
A Doppler shift estimation system with relatively high dynamic range is conceived and demonstrated. The scheme is based on dual mixing the modulated radar echo and frequency to voltage mapping. Hence, it needs no radio frequency auxiliary part. This makes the system capable of becoming integrated into any photonic radar, which would positively affect ...

The Ratio of Metastatic to Examined Lymph Nodes Is a Powerful Independent Prognostic Factor in Rectal Cancer

Annals of Surgery, 2008
The aim of the study was to evaluate the prognostic value of the ratio of metastatic to examined lymph nodes (LNR) in patients with rectal cancer.Lymph nodes ratio (LNR) has been shown to have prognostic value in patients with colon cancer. The impact of LNR on disease-free and overall survival in patients with rectal cancer is unknown.From 1998 to ...

Blue Ribbon Power: Independent Commissions and UN Reform

International Studies Perspectives, 2000
In planning a reform project, it is essential to take into account existing political realities and the limits they are likely to impose on what is achievable. At the same time, it should be recognized that a primary purpose of such studies by civil society groups is to expand and redefine those boundaries, in the process rebuilding political will ...

Highly Sensitive Power Independent Frequency Measurement System

IEEE Microwave and Wireless Components Letters, 2015
A broadband frequency measurement system capable of measuring both frequency and amplitude of an RF signal with $-$ 31 dBm sensitivity and 100 MHz accuracy over 40 MHz to 40 GHz range is practically demosntrated. The amplitude independence was achieved via employing two orthogonal measurements and the high sensitivity was obtained by utilization of ...

High-Power, Independently Wavelength, Power, and Linewidth Tunable Ytterbium Fiber Laser

IEEE Photonics Technology Letters, 2019
We report a high-power, independently tunable wavelength, linewidth, and power, continuous-wave Ytterbium-doped fiber laser. Our system is based on a simple master oscillator power amplifier configuration, which decouples the output power from the output wavelength and linewidth.

Control System of 3KW Wind Power Independent Power Supply for 3G Base Station

2009 Second International Symposium on Knowledge Acquisition and Modeling, 2009
This paper studies control system operation and control strategy of 3KW wind power generation for 3G base station. The system merges into 3G base stations to save power in order to fully ensure that base stations can get supply power normally in any case.
