We utilise hydroxyl observations from the MLS/Aura satellite instrument to study the latitudinal extent of particle forcing in the northern polar region during the January 2005 solar proton event. MLS is the first satellite instrument to observe HOx changes during such an event. We also predict the hydroxyl changes with respect to the magnetic latitude by the Sodankylä Ion and Neutral Chemistry...

The segmentation of urban scene mobile laser scanning (MLS) data into meaningful street objects is a great challenge due to the scene complexity of street environments, especially in the vicinity of street objects such as poles and trees. This paper proposes a three-stage method for the segmentation of urban MLS data at the object level. The original unorganized point cloud is first voxelized, ...

Moving-Least Squares (MLS) surfaces are a popular way to define a smooth manifold surface from a set of unorganized points without normals. In this paper we present a formulation of MLS surfaces that sheds light on shortcomings of the original technique proposed by Levin, which is based on a two-step minimization procedure. We show that there are cases intrinsic to the geometry of the underlyin...

In this paper we propose and demonstrate a method to obtain simultaneous dual source-receiver impulse responses in acoustical systems using binary maximum-length sequences (MLS). A binary MLS and its reversed-order sequence form a reciprocal MLS pair. Their correlation property includes a two-valued "pulse-like" autocorrelation function and a relatively smaller-valued cross-correlation function...

The event-condition-action paradigm (also known as triggers or rules) is a powerful technology. It gives a database “active” capabilities – the ability to react automatically to changes in the database or in the environment. One potential use of this technology is in the area of multilevel secure (MLS) data processing, such as, military, where the subjects and objects are classified into differ...

PURPOSE The purpose of this study was to investigate the therapeutic and protective effects of molsidomine (MLS) against doxorubicin (DOX)-induced renal damage in rats. METHODS Forty rats were randomly divided into five groups (control, MLS, DOX, DOX+MLS and MLS+DOX groups). Thiobarbituric acid reactive substance (TBARS), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), ...

Aims To compare changes in gait kinematics and walking speed 24 months after conventional (C-MLS) minimally invasive (MI-MLS) multilevel surgery for children with diplegic cerebral palsy (CP). Methods A retrospective analysis of 19 following C-MLS, mean age at 12 years five (seven ten to 15 11 months), 36 MI-MLS, seven one month 14 was performed. The Gait Profile Score (GPS) were collected preo...

Moving least squares (MLS) surfaces representation directly defines smooth surfaces from point cloud data, on which the differential geometric properties of point set can be conveniently estimated. Nowadays, the MLS surfaces have been widely applied in the processing and rendering of point-sampled models and increasingly adopted as the standard definition of point set surfaces. We classify the ...

OBJECTIVES/HYPOTHESIS Microlaryngeal surgery (MLS) presents ergonomic challenges to surgeons and potential risks for developing musculoskeletal symptoms (MSSx). This study describes prevalence and risk factors of MLS-associated MSSx. STUDY DESIGN Cross-sectional survey. METHODS A questionnaire was administered to members of the American Academy of Otolaryngology-Head and Neck Surgery. Outco...
