Structure of level sets and Sard-type properties of Lipschitz maps [PDF]

open access: yes, 2013
We consider certain properties of maps of class C2 from Rd to Rd−1 that are strictly related to Sard’s theorem, and we show that some of them can be extended to Lipschitz maps, while others require some additional regularity.

Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

The study of anatomy of main pancreatic duct and its variations. [PDF]

open access: yesPerspectives In Medical Research, 2019
Introduction: The duct system of pancreas consists of two large ducts – Main pancreatic duct and Accessory pancreatic duct. Both these ducts drain the entire exocrine part of pancreas. Main pancreatic duct is always present while accessory pancreatic

Dynamic Effects of Social Media Information on Command and Control Performance

open access: yes, 2023
The success of military and civilian Command and Control (C2) depends on the ability of C2 entities to adapt to dynamic changes in situations. With increased exposure to the public and social media, it is critical to understand the way C2 teams use ...

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

Phase space shifts in command structures in networked systems

open access: yes, 2010
This paper presents the rationale behind an important enhancement to the NATO SAS-050 approach space, combined with empirical results which take advantage of these enhancements. In Part 1 a new theoretical legacy for the NATO model is presented.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
