Architected Lattices with a Topological Transition
Advanced Engineering Materials, EarlyView., 2023 This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Scalable distributed-memory external sorting [PDF]
2010 IEEE 26th International Conference on Data Engineering (ICDE 2010), 2010 We engineer algorithms for sorting huge data sets on massively parallel machines. The algorithms are based on the multiway merging paradigm. We first outline an algorithm whose I/O requirement is close to a lower bound. Thus, in contrast to naive implementations of multiway merging and all other approaches known to us, the algorithm works with just two

Approximate Range Searching in External Memory [PDF]
Algorithmica, 2007 In this paper, we present two linear-size external memory data structures for approximate range searching. Our first structure, the BAR-B-tree, stores a set of N points in R d and can report all points inside a query range Q by accessing O(log B N¿+¿e ¿ ¿+¿k e /B) disk blocks, where B is the disk block size, ¿=¿1¿-¿d for convex queries and ¿=¿-¿d ...

Performance of VIDEBAS in an operational environment [PDF]
, 1984 VIDEBAS is a relational database management system in which a database consists of two parts, namely a “real-only” and an “update” part. The first part remains unmodified until the next reorganization and exploits redundancy to achieve fast access to ...

Lightweight Data Indexing and Compression in External Memory [PDF]
Algorithmica, 2010 In this paper we describe algorithms for computing the BWT and for building (compressed) indexes in external memory. The innovative feature of our algorithms is that they are lightweight in the sense that, for an input of size $n$, they use only ${n}$ bits of disk working space while all previous approaches use $\Th{n \log n}$ bits of disk working ...

Using Hashing to Solve the Dictionary Problem (In External Memory) [PDF]
, 2011 We consider the dictionary problem in external memory and improve the update time of the well-known buffer tree by roughly a logarithmic factor. For any \lambda >= max {lg lg n, log_{M/B} (n/B)}, we can support updates in time O(\lambda / B) and queries ...

Photon echo quantum memories in inhomogeneously broadened two level atoms [PDF]
, 2011 Here we propose a solid-state quantum memory that does not require spectral holeburning, instead using strong rephasing pulses like traditional photon echo techniques.

Effects of Preparation on Internal and External Memories [PDF]
, 1996 The aim of the present study was to examine the effect of preparation on the characteristics of imagined and perceptual memory descriptions. Following recent research (Alonso?Quecuty, 1990; Suengas & Johnson, 1988) it was hypothesized that subjects' real memories in the "preparation condition" (i.e.

Memory-Augmented Temporal Dynamic Learning for Action Recognition
, 2019 Human actions captured in video sequences contain two crucial factors for action recognition, i.e., visual appearance and motion dynamics. To model these two aspects, Convolutional and Recurrent Neural Networks (CNNs and RNNs) are adopted in most ...
