Beyond Thin Film Limits—Superhard and Hydrogen‐Free Amorphous Carbon Coatings With Over 100 µm Thickness

Advanced Functional Materials, EarlyView.
For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Advanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.

Structural Divergence Between the Moltbook AI‐Agent Network and Human Social Networks

Advanced Science, EarlyView.
Analysis of the Moltbook AI‐agent network reveals a striking combination of familiar global scaling and distinct internal organization. Attention is highly concentrated, reciprocity is limited, connected triads are suppressed, and communities are strongly modular.

Use of power-law analysis to predict abuse or diversion of prescribed medications: proof-of-concept mathematical exploration

BMC Research Notes, 2018
Objective To conduct a proof-of-concept study comparing Lorenz-curve analysis (LCA) with power-law (exponential function) analysis (PLA), by applying segmented regression modeling to 1-year prescription claims data for three medications—alprazolam ...

The truncated distribution of the range for a Wiener process: Application to the stock price [PDF]

Delta Journal of Science, 2016
In this paper, the exact truncated distribution of the stock price (truncated distributionfor the range of a Wiener process) is available among the established results in the field of mathematics (ProbabilityDistributions). Various statistical properties

Characterizing compressibility with Lorenz curves [PDF]

2011 IEEE International Symposium on Information Theory Proceedings, 2011
This paper revisits earlier work on rate distortion behavior of sparse sources, namely it highlights the fact that a graphical sparsity characterization proposed in [1] is a Lorenz curve, a tool for summarizing income inequality that has been used by economists for over a century. The Lorenz curve associated to a memoryless source can be used to obtain

Coordinated Electronic‐Transport Regulation and Multiscale Phonon Scattering in Sb–La Co‐Doped GeTe

Advanced Science, EarlyView.
Synergistic Sb–La co‐doping simultaneously regulates hole concentration and creates strain‐field fluctuations and multiscale structural disorder in GeTe. Electrical transport is preserved, while electronic and lattice thermal conductivities are strongly suppressed.

Strassen's LIL for the Lorenz Curve

Journal of Multivariate Analysis, 1996
The authors prove Strassen's law of the iterated logarithm for the Lorenz process assuming that the underlying d.f. \(F\) and its inverse \(F^{-1}\) are continuous and the moment \(EX^{2+u}\) is finite for some \(u>0\). Previously, the first author, \textit{S. Csörgö} and \textit{L.

A Thirty‐Year Gap: Reviving All‐Nitride Glasses as Processable, High‐Performance Materials

Advanced Science, EarlyView.
Oxygen‐free all‐nitride glasses are revisited in light of new avenues of synthesis, raw material availability, and applications. A semi‐empirical analysis predicts mechanical performance achieving the level of engineering ceramics while maintaining visual transparency, and significant potential regarding optical properties into the infrared spectral ...
