Analysis of Potential Co-Benefits for Bicyclist Crash Imminent Braking Systems [PDF]
, 2017 In the US, the number of traffic fatalities has had a long term downward trend as a result of advances in the crash worthiness of vehicles. However, these improvements in crash worthiness do little to protect other vulnerable road users such as ...

Automatic Modulation Classification of LFM and Polyphase-coded Radar Signals [PDF]
Radioengineering, 2017 There are several techniques for detecting and classifying low probability of intercept radar signals such as Wigner distribution, Choi-Williams distribution and time-frequency rate distribution, but these distributions require high SNR. To overcome this

Evolution of Netted Radar Systems
IEEE Access, 2020 The netted radar systems are known for being able to provide higher target detection probabilities, more accurate measurements, and better multi-target tracking performance than the monostatic/bistatic radar systems by exploiting information fusion ...

Advanced Science, Volume 13, Issue 1, 5 January 2026.An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

The Continuing Quest for Missile Defense: When Lofty Goals Confront Reality
, 2018 For almost three quarters of a century, the United States has spent billions of dollars and countless person-hours in the pursuit of a national missile defense system that would protect the country from intercontinental ballistic missiles (ICBM) carrying

Huckleberry Habitat and Its Influence on Two Small Populations of Grizzly Bears (Ursus arctos)
Ecology and Evolution, Volume 16, Issue 1, January 2026.We modeled habitat of an important seasonal food item for two Threatened (United States Endangered Species Act) populations of grizzly bears. Our findings suggest that huckleberry habitat is not limiting but does have the potential to influence population density, dispersal/range expansion, energetics, and body size.

Power minimization based robust OFDM radar waveform design for radar and communication systems in coexistence. [PDF]
, 2015 This paper considers the problem of power minimization based robust orthogonal frequency division multiplexing (OFDM) radar waveform design, in which the radar coexists with a communication system in the same frequency band.

Cognitive MIMO Frequency Diverse Array Radar with High LPI Performance
International Journal of Antennas and Propagation, 2016 Frequency diverse array (FDA) has its unique advantage in realizing low probability of intercept (LPI) technology for its dependent beam pattern. In this paper, we proposed a cognitive radar based on the frequency diverse array multiple-input multiple ...

Environmetrics, Volume 37, Issue 1, January 2026.ABSTRACT Airborne particulate matter (PM2.5$$ {\mathrm{PM}}_{2.5} $$) is a major public health concern in urban environments, where population density and emission sources exacerbate exposure risks. We present a novel Bayesian spatiotemporal fusion model to estimate monthly PM2.5$$ {\mathrm{PM}}_{2.5} $$ concentrations over Greater London (2014–2019 ...

A comparison between nocturnal aural counts of passerines and radar reflectivity from a Canadian weather surveillance radar [PDF]
, 2010 Using a Canadian weather surveillance radar (CWSR), we assessed the relationship between aural passerine counts and radar reflectivity during autumn migration on 16 nights.
