On the Temporal Variability of Precipitation in Iraq: Arid‐Wet Years and Extreme Events
International Journal of Climatology, EarlyView.Daily and monthly precipitation data in Iraq display high seasonal to interdecadal variability, with arid and wet years that have very distinct seasonal cycles. Monthly rainfall is significantly correlated with the Indian Ocean Dipole. Extreme events are identified and classified as belonging to four different weather patterns, allowing to obtain daily

Constructing the Neumann series -- an example
The Neumann series for the integral equation \(\theta(\xi)=\theta_ 0+\nu\int^ \ell_ 0\theta(\varepsilon)K(\xi,\varepsilon)d\varepsilon\), in which \(K(\xi,\varepsilon)=\{\xi\text{ for } \xi\varepsilon\}\), leads to the solution \(\theta(\xi)=\theta_ 0\times\sec\sqrt \nu\ell\cos\sqrt \nu(\ell-\xi)\), for every \(\nu\) distinct of an eigenvalue \(\nu_ j=[

Laser &Photonics Reviews, EarlyView.This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Stochastic Second-Order Optimization via von Neumann Series
, 2016 A stochastic iterative algorithm approximating second-order information using von Neumann series is discussed. We present convergence guarantees for strongly-convex and smooth functions. Our analysis is much simpler in contrast to a similar algorithm and its analysis, LISSA.

Efficient First‐Principles Inverse Design of Nanolasers
Laser &Photonics Reviews, EarlyView.This article introduces a first‐principles inverse‐design framework for nanolasers that directly incorporates nonlinear lasing physics. By unifying steady‐state ab‐initio laser theory (SALT) with topology optimization, it reveals how spatial hole burning, gain saturation, and cavity‐emitter coupling shape laser performance, enabling efficient discovery
