LPI Sequences Optimization Method against Summation Detector Based on FFT Filter Bank

Remote Sensing
Waveform design is a crucial factor in electronic surveillance (ES) systems. In this paper, we introduce an algorithm that designs a low probability of intercept (LPI) radar waveform. Our approach directly minimizes the detection probability of summation

Long‐term periodontal and peri‐implant tissue stability under supportive therapy

Periodontology 2000, EarlyView.
Abstract Background Supportive periodontal and peri‐implant maintenance therapy is strongly associated with improved long‐term retention and stability of natural teeth and dental implants. Lack of regular professional follow‐up after initial therapy is a major risk factor for disease recurrence and tooth or implant loss.

Techniques for homodyne dechirp-on-receive linearly frequency modulated radar [PDF]

, 2011
This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response function of the radar is ...

Deep Spatially Varying Coefficient Model for Interpolation of Non‐Stationary Meteorological Data

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT In spatial statistics, the spatially varying coefficient model (SVCM) is widely applied in the analysis and interpolation of non‐stationary spatial data. By incorporating spatially varying coefficients, the model can capture spatial heterogeneity and provide an attractive interpretation of response‐covariate associations.

Introduction to Noise Radar and Its Waveforms

Sensors, 2020
In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy

From armed roots to airline routes in South America: A dual imprinting perspective

Strategic Management Journal, Volume 47, Issue 8, Page 2235-2271, August 2026.
Abstract Reserch Summary We propose that founding partner relationships can leave distinct imprints on organizations that differ in durability and in how they respond to subsequent changes involving the founding partner. Examining South American airlines founded between 1919 and 1984, we argue and find that such relationships simultaneously create an ...
