Speeding-up $q$-gram mining on grammar-based compressed texts

open access: yes, 2012
We present an efficient algorithm for calculating $q$-gram frequencies on strings represented in compressed form, namely, as a straight line program (SLP).

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

open access: yesAdvanced Science, EarlyView.
This study identifies a trypsin‐like serine protease, ZmNAL1a, that moves from leaves to the shoot apical meristem. ZmNAL1a promotes the floral transition by degrading TOPLESS‐like corepressor REL2, which thereby enhances the expression of key flowering genes through elevating histone acetylation and relieving REL2–ZmEREBP147‐mediated transcriptional ...

On an inclusion theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We have established a relation between θ−|R,pn|k and θ−|R,qn|k summability methods, k>1, which generalizes a result of Sunouchi (1949) on |R,pn| and |R,qn| summability methods.

The edge slide graph of the n-dimensional cube : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Mathematics at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2017
The goal of this thesis is to understand the spanning trees of the n-dimensional cube Qn by understanding their edge slide graph. An edge slide is a move that “slides” an edge of a spanning tree of Qn across a two-dimensional face, and the edge slide ...

Active Thermal Metasurfaces Enable Superscattering of Thermal Signatures Across Arbitrary Shapes and Thermal Conductivities

open access: yesAdvanced Science, EarlyView.
This study proposes a thermal superscatterer capable of manipulating thermal scattering signatures far exceeding the actual scale of objects. Utilizing transformation thermotics and active thermal metasurfaces, the device reproduces the thermal scattering signature of the enlarged thermal scatterer.

Snellius versneld [PDF]

open access: yes, 2001
Practically all computations of the value of ? before 1600 were done using Archimedes' method. As is well-known, this method consists of approximation of the circle with diameter 1 by inscribed and circumscribed regular polygons. Denote the circumference

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

open access: yesAdvanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.
