What are the main contributing factors to road accidents? Factors such as inexperience, lack of skill, and risk-taking behaviors have been associated with collisions young drivers. In contrast, visual, cognitive, mobility impairment older We investigated causes accidents by drawing on multiple sources: expert views police officers, lay driving public, official accident records. Studies 1 2, officers public were asked about typical traffic using hypothetical scenarios. Study 3, we whether...
Introduction: Concerns have been raised that the nonlinear relation between crashes and travel exposure invalidates conventional use of crash rates to control for exposure. A new metric bears a linear association was used as basis calculating unbiased risks. This study compared two methods – adjusted risk assessing effect driver age, gender, time day on involvement fatality. Method: We police reports single-car multi-car with fatal nonfatal injuries occurred during 2002–2012 in Great...
Background: To determine whether accounting for posterior corneal surgically induced astigmatism (SIA) would improve toric intraocular lens power calculation prediction error. Methods: A total of 189 eyes 148 patients undergoing routine cataract surgery were included in the study. Standard and keratometry measured pre- postoperatively. Centroid SIA with standard calculated separately. Prediction errors postoperative refractive at 4 weeks postoperatively compared Barrett Toric predicted...
Introduction: Motor-vehicle crashes are a leading cause of death in adolescence and young adults. A multitude factors, including skill level, inexperience, risk taking behaviors associated with drivers’ crashes. This research investigated whether combinations factors underlie involving drivers. Method: retrospective longitudinal study was conducted on population-wide one- two-car Great Britain during years 2005–2012 per driver age (17–20, 21–29, 30–39, 40–49) sex. Reporting officers provided...
AIM: To assess the reliability of web-based version ocular surface disease index in Chinese (C-OSDI) on clinically diagnosed dry eye (DE) patients. METHODS: A total 254 participants (51% male, 129/254; mean age: 27.90±9.06y) with DED completed paper- and versions C-OSDI questionnaires a randomized crossover design. Ophthalmology examination diagnosis were performed prior to being invited join study. Participants randomly designated either group (paper-based first second) or B (web-based...
Purpose: Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of surface can be achieved independent lacrimal gland function. Methods: This prospective, open-label pilot study included 60 eyes 30 diabetic patients diagnosed with dry eye disease (DED) were randomly assigned to either DQS (n = eyes) or hyaluronate (HA) group eyes). Participants in received 3%...
To assess whether the use of measured posterior corneal astigmatism (PCA) values improves prediction accuracy toric intraocular lens power formulas, compared to predicted PCA values, when orientation steep axis is non-vertical.
Abstract Stellar surface magnetoconvection (granulation) creates asymmetries in the observed stellar absorption lines that can subsequently manifest themselves as spurious radial velocities (RVs) shifts. In turn, this then mask Doppler reflex motion induced by orbiting planets on their host stars and represents a particular challenge for determining masses of low-mass, long-period planets. Herein, we study impact creating Sun-as-a-star observations encapsulate granulation variability...
We consider coupling conditions for the "Aw–Rascle" (AR) trafficflow model at an arbitrary road intersection. In contrast with previously introduced in [10] and [7], all moments of AR systemare conserved total flux junction is maximized. This nonlinearoptimization problem solved completely. show how two simple casesof merging diverging junctions can be extended to more complex junctions,like roundabouts. Finally, we present some numerical results.
In this paper, we propose a simple fully discrete hybrid model for vehicular traffic flow, which both the macroscopic and microscopic models are based on Lagrangian discretization of Aw–Rascle (AR) [A. Aw M. Rascle, SIAM J. Appl. Math., 60 (2000), pp. 916–938]. This hybridization makes use relation between AR follow-the-leader-type [D. C. Gazis, R. Herman, W. Rothery, Oper. Res., 9 (1961), 545–567; Herman I. Prigogine, Kinetic Theory Vehicular Traffic, American Elsevier, New York, 1971],...
Recently, Berthelin et al., 4 introduced a traffic-flow model describing the formation and dynamics of traffic jams. This which consists Constrained Pressureless Gas Dynamics system assumes that maximal density constraint is independent velocity. However, in practice, distribution vehicles on highway depends their In this paper, more realistic namely Second Order Model with Constraints (in short SOMC) proposed, derived from Aw Rascle model, 1 takes into account feature. Moreover, when...

This study assessed the efficacy and safety of intense pulsed light (IPL) therapy in participants with severe evaporative dry eye disease (DED).This randomized, controlled, single-center included 49 adult (≥ 18 years) DED who received either IPL (n = 56 eyes) or sham 42 three times. The primary parameters were ocular surface index (OSDI) score, non-invasive tear breakup time (NITBUT), film lipid layer (TFLL), conjunctivocorneal staining score (CS), MG Score, meibomian gland (MG) quality,...
<abstract><p>In this study, we introduce and investigate a new class of split inverse problems, comprising multidimensional parameter evolution, which call the variational inequality problem with multiple output sets. To demonstrate its applicability, formulate equilibrium flow traffic network models for an arbitrary number locations. We define Wardrop condition sets establish equivalence formulated models. then existence uniqueness equilibria our proposed model. In addition,...
Lane changing is one of the most common maneuvers on motorways. Although macroscopic traffic models are well known for their suitability to describe fast moving crowded traffic, these generally developed in a one-dimensional framework; henceforth lane-changing behavior either not explicitly modeled or forbidden. In this paper, we propose model which accounts motorways, based two-dimensional extension Aw and Rascle [SIAM J. Appl. Math., 60 (2000), pp. 916--938] Zhang [Transport. Res. B-Meth.,...

This paper deals with intersections' modeling for vehicular traffic flow governed by the Lighthill $\&$ Whitham [24] and Richards [26] model. We present a straightforward reformulation of recent models, introduced in [19] [4], using description terms supply demand functions [22, 6]. formulation is used to state new model which takes into account possible storage capacity an intersection as seen roundabouts or highway on-ramps. discuss Riemann problem at junction numerical simulations.
