Valuing Natural Space and Landscape Fragmentation in Richmond, VA [PDF]
, 2016 Hedonic pricing methods and GIS (Geographic Information Systems) were used to evaluate relationships between sale price of single family homes and landscape fragmentation and natural land cover. Spatial regression analyses found that sale prices increase

Measuring von Neumann entanglement entropies without wave functions [PDF]
, 2019 We present a method to measure the von Neumann entanglement entropy of ground states of quantum many-body systems which does not require access to the system wave function.

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐

Adaptation dynamics of the quasispecies model
, 2008 We study the adaptation dynamics of an initially maladapted population evolving via the elementary processes of mutation and selection. The evolution occurs on rugged fitness landscapes which are defined on the multi-dimensional genotypic space and have ...

Wave functions and properties of massive states in three-dimensional supersymmetric Yang-Mills theory [PDF]
, 2001 We apply supersymmetric discrete light-cone quantization (SDLCQ) to the study of supersymmetric Yang-Mills theory on R x S^1 x S^1. One of the compact directions is chosen to be light-like and the other to be space-like.

Row Crops and the U.S. Agricultural Trade Deficit: Recent Trends and Policy Issues
Applied Economic Perspectives and Policy, Volume 47, Issue 5, Page 1759-1773, December 2025.ABSTRACT Row crops such as soybeans, corn, wheat, and cotton are the backbone of the U.S. farm sector, accounting for around $60 billion of exports in 2023. While U.S. row crop exports remain robust, growing concerns over the rising U.S. agricultural trade deficit underscore the need to appraise the ongoing market and policy dynamics affecting the ...

Automatic LPI Radar Waveform Recognition Using CNN
IEEE Access, 2018 Detecting and classifying the modulation scheme of the intercepted noisy low probability of intercept (LPI) radar signals in real time is a necessary survival technique required in the electronic warfare systems. Therefore, LPI radar waveform recognition
