Vertically aligned carbon nanotube arrays - Wikipedia
In materials science, vertically aligned carbon nanotube arrays (VANTAs) are a unique microstructure consisting of carbon nanotubes oriented with their
Frozen photons in Jaynes Cummings arrays
We study the origin of "frozen" states in coupled Jaynes-Cummings-Hubbard arrays in the presence of losses. For the case of half the array initially populated with photons while the other half is left empty we show the emergence of self-localized pho...
Beamforming Techniques for Large-N Aperture Arrays
Beamforming is central to the processing function of all phased arrays and becomes particularly challenging with a large number of antenna element (e.g. >100,000). The ability to beamform efficiently with reasonable power requirements is discussed in...
Characterization of Low-noise Backshort-Under-Grid Kilopixel Transition Edge Sensor Arrays…
We present laboratory characterization of kilo-pixel, filled backshort-under-grid (BUG) transition-edge sensor (TES) arrays developed for the Primordial Inflation Polarization ExploreR (PIPER) balloon-borne instrument. PIPER is designed to map the po...
Sub-Kelvin cooling for two kilopixel bolometer arrays in the PIPER receiver
The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne telescope mission to search for inflationary gravitational waves from the early universe. PIPER employs two 32x40 arrays of superconducting transition-edge sensors, which opera...
Guided Neuronal Growth on Arrays of Biofunctionalized GaAs/InGaAs Semiconductor Microtubes
We demonstrate embedded growth of cortical mouse neurons in dense arrays of semiconductor microtubes. The microtubes, fabricated from a strained GaAs/InGaAs heterostructure, guide axon growth through them and enable electrical and optical probing of...

Nusselt number for steady periodically developed heat transfer in micro- and mini-channels…
In this work, the Nusselt number is examined for periodically developed heat transfer in micro- and mini-channels with arrays of offset strip fins, subject to a constant heat flux. The Nusselt number is defined on the basis of a heat transfer coeffic...
Developed and quasi-developed macro-scale heat transfer in micro- and mini-channels with a…
In the present work, we examine to what degree the heat transfer can be described as developed on a macro-scale level in typical micro- and mini-channels with offset strip fin arrays subject to a uniform heat flux, considering flow entrance and side-...
Partial Shading Detection and Smooth Maximum Power Point Tracking of PV Arrays under PSC
One of the most important issues in the operation of a photovoltaic (PV) system is extracting maximum power from the PV array, especially in partial shading condition (PSC). Under PSC, P-V characteristic of PV arrays will have multiple peak points, o...
The existence of square non-integer Heffter arrays
A Heffter array $H(n;k)$ is an $n\times n$ matrix such that each row and column contains $k$ filled cells, each row and column sum is divisible by $2nk+1$ and either $x$ or $-x$ appears in the array for each integer $1\leq x\leq nk$. Heffter arrays a...
Pencil-Beam Single-point-fed Dirac Leaky-Wave Antenna on a Transmission-Line Grid
Leaky-wave antennas (LWAs) are widely used as single-point-fed linear antenna arrays. The extension of LWAs to 2D implies that they can be used as single-point-fed 2D antenna arrays without requiring a complex feeding network. However, generating a p...
Maskless Generation of Single Silicon Vacancy Arrays in Silicon Carbide by a Focused He+ I…
Precise generation of spin defects in solid-state systems is essential for nanostructure fluorescence enhancement. We investigated a method for creating single silicon vacancy defect arrays in silicon carbide using a helium-ion microscope. Maskless a...
NumPy meshgrid () - Programiz
The meshgrid () method takes two or more 1D arrays representing coordinate values and returns a pair of 2D arrays.
NumPy Meshgrid: Create Coordinate Arrays in Python
Sep 15, 2025 · In this comprehensive guide, weâll explore what coordinate arrays are, how NumPyâs meshgrid function works its magic, and how you can leverage it to simplify your Python projects, â¦

Breaking the $O(n)$-Barrier in the Construction of Compressed Suffix Arrays and Suffix Tre…
The suffix array and the suffix tree are the two most fundamental data structures for string processing. For a length-$n$ text, however, they use $Θ(n \log n)$ bits of space, which is often too costly. To address this, Grossi and Vitter [STOC 2000]...
Suffix Trays and Suffix Trists: Structures for Faster Text Indexing
Suffix trees and suffix arrays are two of the most widely used data structures for text indexing. Each uses linear space and can be constructed in linear time for polynomially sized alphabets. However, when it comes to answering queries with worst-ca...
In-Place Sparse Suffix Sorting
Suffix arrays encode the lexicographical order of all suffixes of a text and are often combined with the Longest Common Prefix array (LCP) to simulate navigational queries on the suffix tree in reduced space. In space-critical applications such as sp...
Energy Efficiency Maximization of Massive MIMO Communications With Dynamic Metasurface Ant…
Future wireless communications are largely inclined to deploy massive numbers of antennas at the base stations (BSs) by leveraging cost- and energy-efficient as well as environmentally friendly antenna arrays. The emerging technology of dynamic metas...
