Lateral meniscus injuries have more impact on pivot shift than anterolateral complex injuries in anterior cruciate ligament‐injured knees

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this prospective study was to investigate the effect of Kaplan fibres (KF), anterolateral ligament (ALL) and lateral meniscus (LM) injuries on preoperative anterolateral rotational instability (ALRI) in anterior cruciate ligament (ACL)‐injured knees.

A Heterogeneous Glider System with Underwater Acoustic Communication and Positioning

open access: yesPolish Maritime Research
Autonomous underwater vehicles are increasingly frequently used in the fields of ocean observation, data collection, and tactical surveillance. Underwater navigation and near real-time communication are the most important factors limiting the performance

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

open access: yesLaser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

A Computation in a Cellular Automaton Collider Rule 110

open access: yes, 2016
A cellular automaton collider is a finite state machine build of rings of one-dimensional cellular automata. We show how a computation can be performed on the collider by exploiting interactions between gliders (particles, localisations).

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Topological‐defect‐featured order evolution of liquid crystals

open access: yesResponsive Materials, EarlyView.
This review provides a comprehensive introduction to the recent advances in the topological‐defect‐featured order evolution of liquid crystal (LCs), including the stimulus‐driven dynamics of defects in nematic LCs, topological defect morphological transformation during phase transitions, advanced strategies for regulating and applications of ...

The mathematical basis for deterministic quantum mechanics

open access: yes, 2006
If there exists a classical, i.e. deterministic theory underlying quantum mechanics, an explanation must be found of the fact that the Hamiltonian, which is defined to be the operator that generates evolution in time, is bounded from below. The mechanism
