Heights on elliptic curves over number fields, period lattices, and complex elliptic logarithms [PDF]

open access: yes
This thesis presents some major improvements in the following computations: a lower bound for the canonical height, period lattices, and elliptic logarithms.

Elliptic curves and factoring. [PDF]

open access: yes, 2010
The Elliptic Curve Method (ECM) is a powerful and widely used algorithm for factorization which can be implemented with several different forms of elliptic curves. We will give some general background on the theory of elliptic curves and the ideas behind

Unique normal forms near a degenerate elliptic fixed point in two-parametric families of area-preserving maps [PDF]

open access: yes, 2014
We derive simplified normal forms for an area-preserving map in a neighbourhood of a degenerate resonant elliptic fixed point. Such fixed points appear in generic families of area-preserving maps. We also derive a simplified normal form for a generic two-

Adaptive Foam 3D Printing of Ultralight and Multifunctional Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Adaptive foam 3D printing, enabled by expandable microspheres, imparts cellular structures to thermoplastic and thermosetting polymers, manufactured through a variety of processes including fused filament fabrication, direct ink writing, digital light processing, and inkjet printing.

On the confinement of bounded entire solutions to a class of semilinear elliptic systems [PDF]

open access: yes, 2014
Under appropriate assumptions, we show that all bounded entire solutions to a class of semilinear elliptic systems are confined in a convex domain. Moreover, we prove a Liouville type theorem in the case where the domain is strictly convex.

Elliptic curves with a pre-determined embedding degree [PDF]

open access: yes, 2009
A pairing over an elliptic curve E(F_) to an extension field of F_ has begun to be attractive in cryptosystems, where k is called the embedding degree. The cryptosystems using a pairing are called the pairing-based cryptosystems.

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

open access: yesAdvanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Multi-part mirror for focusing diffuse light

open access: yesMechanical Engineering Journal, 2017
In the present study a multi-part mirror is developed for focusing only a scattered light effectively. The multipart mirror is composed from several elliptic mirrors. Several elliptic mirrors are installed on the surface of the multi-part mirror. Primary

On elliptic and quasiregularly elliptic manifolds

open access: yes
In his book "Metric structures for Riemannian and non-Riemannian spaces", Gromov defined two properties of Riemannian manifolds, ellipticity and quasiregular ellipticity, and suggested that there may be a connection between the two. Since then, groups of researchers working independently have proved strikingly similar results about these two concepts ...
