Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

open access: yes, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

Opposite Elements in Clutters [PDF]

open access: yesMathematics of Operations Research, 2018
Let E be a finite set of elements, and let L be a clutter over ground set E. We say distinct elements e, f are opposite if every member and every minimal cover of L contains at most one of e, f. In this paper, we investigate opposite elements and reveal a rich theory underlying such a seemingly simple restriction.

Clutter-Aware Precoder Design for Integrated Sensing and Communication Systems

open access: yesIEEE Access
It is envisaged that next-generation wireless networks will provide integrated sensing and communication (ISAC) functions. Clutter is one of the major factors that degrade the performance of sensing, whereas inter-user interference degrades communication

Does Thinning Homogenous and Dense Regrowth Benefit Bats? Radio-Tracking, Ultrasonic Detection and Trapping

open access: yesDiversity, 2018
Renewal ecology promotes the creation and enhancement of landscapes that support biodiversity and ecosystem services for humans. Silvicultural thinning of forest regrowth to reduce tree competition represents a form of active management that may also ...

Location, Location, Location

open access: yesInterdisciplinary Journal of Signage and Wayfinding, 2021
Academic scholars and practitioners uniformly suggest that off-premise signs such as billboards will be more effective if they are installed in high-traffic areas rather than low-traffic areas. In this research, we question the ubiquity of this claim and

Radar Clutter Backscattering Simulation for Specific Sites [PDF]

open access: yes, 2007
The state of development of the surface clutter prediction model DORTE is presented. This simulation program utilizes Digital Elevation Models and land use information to calculate reflectivity maps for specific sites with optional statistical variation ...

Myogenic Fusogen‐Engineered Lipid Nanoparticles Enhance mRNA Delivery in Skeletal Muscle

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a biomimetic strategy of engineering full‐length Myomaker, a muscle‐specific fusogen, into lipid nanoparticles (LNPs) to harness the native myoblast fusion capability for skeletal muscle mRNA delivery. The resulting Mymk‐LNPs enhance transfection in differentiating myocytes and enable Cre‐mediated reporter activation in injured ...

Clutters and Semimatroids

open access: yesEuropean Journal of Combinatorics, 1986
Generalizing the concept of matroid the author introduces the concept of semimatroid, and investigates its fundamental properties. Some open problems concerning semimatroids are stated and discussed in the final section of the paper.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

open access: yesAdvanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Echolocation by the harbour porpoise: Life in coastal waters

open access: yesFrontiers in Physiology, 2013
The harbour porpoise is one of the smallest and most widely spread of all toothed whales. They are found abundantly in coastal waters all around the northern hemisphere.
