Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

Entropy‐Engineered Multi‐Metallic MOFs Unlock High‐Performance Ammonium‐Ion Storage

Small, Volume 22, Issue 45, 13 August 2026.
Entropy‐engineered amino‐functionalized EnMOF‐NH2 cathode with five metal nodes (Co, Ni, Fe, Mn, Mo) enables NH4+ hydrogen‐bonding storage and multi‐metal redox activity, while suppressing metal dissolution. ABSTRACT Aqueous ammonium ion batteries (AAIBs) are an emerging sustainable energy technology owing to their high ionic conductivity, safety, low ...

Prospective external validation of ADNEX and RMI for estimating risk of malignancy in adnexal masses in general gynecological settings: Danish multicenter study

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 256-269, August 2026.
ABSTRACT Objectives The primary aims of this study were to validate externally the diagnostic performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model for distinguishing between malignant and benign adnexal masses, when used by non‐expert ultrasound examiners in general gynecological settings with a low prevalence of ovarian ...

Reconfiguring biofortification strategies to transform food systems and address micronutrient deficiency of the 21st century

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2511-2547, August 2026.
This review explores how to make staple foods and horticultural crops more nutritious, including how artificial intelligence‐based screening of gene banks helps deploy nutritionally rich germplasm into breeding. Genome editing can help develop crops richer in minerals, vitamins, and health‐promoting compounds, supporting healthier diets and more ...

Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, Volume 62, Issue 4, Page 1367-1382, August 2026.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Nitric Oxide Tunes Secreted Metabolite Bioactivity

Molecular Microbiology, Volume 126, Issue 2, Page 145-160, August 2026.
Pseudomonas aeruginosa produces phenazine metabolites that can react with nitric oxide (·NO) to form nitrosylated compounds. The formation of these metabolites results in rapid loss in P. aeruginosa viability and diminishes phenazine antimicrobial activity against other organisms, including Staphylococcus aureus. ABSTRACT The radical nitric oxide (·NO)

Redefining automatic target recognition (ATR) performance standards

Proceedings of SPIE, 2011
Present descriptors for Automatic Target Recognition (ATR) performance are inadequate for use in comparing algorithms that are purported to be a solution to the problem. The use of receiver operator characteristic curves (ROCs) is a defacto standard, but they do not communicate several key performance measures, including (i) intrinsic separation ...

A fuzzy hyperspectral classifier for automatic target recognition (ATR) systems

Pattern Recognition Letters, 1999
In this paper we present a fuzzy system based hyperspectral classifier for automatic target identification. The system is based on partitioning the spectral band space into clusters using a modified fuzzy C-Means clustering algorithm. Classification of each pixel is then carried out by calculating its fuzzy membership in each cluster.

Cascaded automatic target recognition (Cascaded ATR)

Proceedings of SPIE, 2010
The global war on terror has plunged US and coalition forces into a battle space requiring the continuous adaptation of tactics and technologies to cope with an elusive enemy. As a result, technologies that enhance the intelligence, surveillance, and reconnaissance (ISR) mission making the warfighter more effective are experiencing increased interest.
