We report the observation of nonlinear interactions in quadratic nonlinear crystals having a
geometrically twisted susceptibility pattern. The quasi-angular-momentum of these crystals is …

Opto-mechanical interactions in guided wave media are drawing great interest in fundamental
research and applications. Forward stimulated Brillouin scattering, in particular, is widely …

… in the positive z ̂ direction with axial wavenumber K and frequency Ω . The material … index
variations of the same Ω and K , but with the opposite sign: − Δ n 2 , m ( Ω ) . Since K = n Ω / c , …

This study investigates momentum among a host of market anomalies. Using an investment
universe consisting of the 15 top (long-leg) and 15 bottom (short-leg) anomaly portfolios, the …

… 1 per K [31]. The acoustic velocities in the coatings decrease with temperature, with slopes of
−2.4, −2.2 and −12.2 m×s −1 per K … Keren Shemer received the B.Sc. degree in physics and …

Forward Brillouin scattering interactions support the sensing and analysis of media outside
the cladding boundaries of standard fibers, where light cannot reach. Quantitative point-…

Propagation in the cladding modes of standard optical fibers enables the sensing of chemicals
outside the fiber boundary, where light in the single core mode cannot reach. Coupling to …

We experimentally demonstrate that the orbital angular momentum (OAM) of a second
harmonic (SH) beam, generated within twisted nonlinear photonic crystals, depends both on the …

Abstract Knowledge and understanding of risk mechanisms associated with pediatric feeding
disorder (PFD) remain limited. We aimed to investigate factors associated with PFD and …

Aim Understanding the association between pediatric feeding disorder (PFD) and age of
presentation is limited. We aimed to investigate factors associated with PFD among different …
