Advanced Materials Technologies, EarlyView.A flexible pressure sensor utilizing a 3D dual‐pore polyurethane structure is developed to overcome the intrinsic trade‐off between sensitivity and linearity. By inducing sequential buckling through distinct pore sizes and shapes, the device achieves highly linear and sensitive responses across a wide pressure range.

Periods of elliptic surfaces with $p_g=q=1$
Forum of Mathematics, SigmaWe prove that the period mapping is dominant for elliptic surfaces over an elliptic curve with $12$ nodal fibers, and that its degree is larger than $1$ . This settles the final case of infinitesimal Torelli for a generic elliptic surface.

Non-vanishing of Artin-twisted L-functions of elliptic curves [PDF]
, 2013 Let E be an elliptic curve and ρ an Artin representation, both defined over Q. Let p be a prime at which E has good reduction. We prove that there exists an infinite set of Dirichlet characters χ, ramified only at p, such that the Artin-twisted L-values ...

On‐Chip Saturated Absorption of CO2 in a Silicon‐on‐Sapphire Waveguide
Advanced Optical Materials, EarlyView.We demonstrate the first saturated absorption of a molecular gas on a planar photonic chip. By coupling carbon dioxide with the tightly confined light of a silicon‐on‐sapphire waveguide, we achieve optical saturation using only milliwatt powers. This breakthrough provides a practical, low‐power foundation for creating ultra‐compact mid‐infrared ...

Descent Via Isogeny on Elliptic Curves with Large Rational Torsion Subgroups.
, 2008 We outline PARI programs which assist with various algorithms related to descent via isogeny on elliptic curves. We describe, in this context, variations of standard inequalities which aid the computation of members of the Tate-Shafarevich group.
