Elmi, Zeinab (author), Li, Bokang (author), Liang, Benbu (author), Lau, Yui yip (author), Borowska-Stefańska, Marta (author), Wiśniewski, Szymon (author), Dulebenets, Maxim A. (author)Time management is crucial for liner shipping services. A variety of unexpected events can disrupt liner shipping schedules. A real-time port capacity analysis and rescheduling the original ship operations would be necessary to counteract the negative effects of such disruptions. Different ship schedule recovery options can be adopted in...journal article 2023

Lau, Erica (author), Hou, H. (author), Lai, Joseph H.K. (author), Edwards, David (author), Chileshe, Nicholas (author)While the performance of sports facilities such as swimming pools is crucial to the health, safety and enjoyment of pool users, little research has been conducted to explore how to analytically evaluate the holistic performance of such facilities from the users' perspective. Even an evaluation framework portraying the key performance attributes...journal article 2021

Geier, Max (author), Fulga, Ion Cosma (author), Lau, A. (author)We study a link between the ground-state topology and the topology of the lattice via the presence of anomalous states at disclinations – topological lattice defects that violate a rotation symmetry only locally. We first show the existence of anomalous disclination states, such as Majorana zero-modes or helical electronic states, in second...journal article 2021

Lau, Y.M. (author), Westerweel, J. (author), van de Water, W. (author)We use Faraday waves to measure interfacial tension σ between two immiscible fluids, with an interest in (ultra)low values of σ. The waves are excited by vertically oscillating the container in which the fluids reside. Using linear stability theory, we map out the accessible range of interfacial tensions. The smallest value (σmin ≈ 5 × 10-4 N...journal article 2020

(author), Qu, Huamin (author)Recent attempts at utilizing visual analytics to interpret Recurrent Neural Networks (RNNs) mainly focus on natural language processing (NLP) tasks that take symbolic sequences as input. However, many real-world problems like environment pollution forecasting apply RNNs on sequences of multi-dimensional data where each dimension represents an...conference paper 2020

Varjas, D. (author), Lau, A. (author), Pöyhönen, K.K. (author), Akhmerov, A.R. (author), Pikulin, Dmitry I. (author), Fulga, Ion Cosma (author)We construct a two-dimensional higher-order topological phase protected by a quasicrystalline eightfold rotation symmetry. Our tight-binding model describes a superconductor on the Ammann-Beenker tiling hosting localized Majorana zero modes at the corners of an octagonal sample. In order to analyze this model, we introduce Hamiltonians...journal article 2019

(author), Dekker, C. (author)Liquid-liquid phase separation (LLPS), especially coacervation, plays a crucial role in cell biology, as it forms numerous membraneless organelles in cells. Coacervates play an indispensable role in regulating intracellular biochemistry, and their dysfunction is associated with several diseases. Understanding of the LLPS dynamics would...journal article 2019

Lau, A. (author), Ray, Rajyavardhan (author), Varjas, D. (author), Akhmerov, A.R. (author)We study the influence of sample termination on the electronic properties of the novel quantum spin Hall insulator monolayer 1T′-WTe2. For this purpose, we construct an accurate, minimal four-orbital tight-binding model with spin-orbit coupling by employing a combination of density-functional theory calculations, symmetry considerations, and...journal article 2019

Lau, A. (author), Ortix, Carmine (author)We theoretically show that IV-VI semiconducting compounds with lowerature rhombohedral crystal structure represent a new potential platform for topological semimetals. By means of minimal k·p models, we find that the two-step structural symmetry reduction of the higherature rocksalt crystal structure, comprising a rhombohedral distortion...journal article 2019

Lau, A. (author), Ortix, Carmine (author)We discuss recent advances in the study of topological insulators protected by spatial symmetries by reviewing three representative, theoretical examples. In three dimensions (3D), these states of matter are generally characterized by the presence of gapless boundary states at surfaces that respect the protecting spatial symmetry. We discuss...journal article 2018

Fanalista, F. (author), Deshpande, S.R. (author), Lau, A.W.H.R. (author), Pawlik, G. (author), Dekker, C. (author)Recently, both the cellular and synthetic biology communities have expressed a strong interest in coacervates, membrane‐less liquid droplets composed of densely packed multivalent molecules that form as a result of spontaneous phase separation. Here, it is studied how FtsZ, a protein that plays a key role in the bacterial division process,...journal article 2018

Gui, Tao (author), Zhou, Gai (author), Lu, Chao (author), Lau, Alan Pak Tao (author), Wahls, S. (author)The recently proposed b-modulation method for nonlinear Fourier transform-based fiber-optic transmission offers explicit control over the duration of the generated pulses and therewith solves a longstanding practical problem. The currently used b-modulation however suffers from a fundamental energy barrier. There is a limit to the energy of...journal article 2018

Gamme, S. (author), De Oliveira Andrade, G.L. (author), Ragni, D. (author), Lau, F. (author)A fast, linear scaling vortex method is presented to study inviscid incompressible flow problems involving one or more actuator disks. Building upon previous efforts that were limited to axi-symmetric flow cases, the proposed methodology is able to handle arbitrary configurations with no symmetry constraints. Applications include the conceptual...conference paper 2017

(author)There are many ways to learn from data. Our first experiment consisted in reproducing the way aerodynamicists work [2] with a genetic optimizer. The data pool was too narrow and asymptotic tendencies were unreliable. Our 2nd Experiment, a simple version of [4], had a virtually unlimited data pool and used neural networks. Results were better,...poster 2016

Lau, G.K. (author), Goosen, J.F.L. (author), Duc, T.C. (author), Van Keulen, F. (author)This paper presents an overview of a new type of thermal micro-actuators using thermally expandable polymers with embedded skeletons. Embedding a stiff skeleton enhances the actuation capability of the thermally expandable polymer. Consequently, the skeleton-reinforced polymers feature a large maximum actuation stress (often above 100 MPa) and a...conference paper 2008
