OBJECTIVES To describe the refractive results of cataract surgery after photorefractive keratectomy (PRK) for patients with myopia, and to find a more accurate method to predict intraocular lens (IOL) power in these cases. DESIGN Nonrandomized, retrospective clinical study. PATIENTS AND METHODS Nine patients (15 eyes) who underwent cataract surgery after prior PRK to correct myopia were ide...

BACKGROUND Many disorders of the musculoskeletal system are caused by modified net joint forces resulting from individual coping movement strategies of patients suffering from neuromuscular diseases. Purpose of this work is to introduce a personalized biomechanical model which allows the calculation of individual net joint forces via inverse dynamics based on anthropometry and kinematics of the...

[1] This study is one of the few attempts to close water and heat budgets in tropical lakes and reservoirs on both daily and monthly time scales. A water budget of Kranji Reservoir is constructed for the year of 2007 using data for water level, reservoir gate operation records, and inflow predicted by a catchment rainfall-runoff model. A heat budget of Kranji Reservoir is also constructed for a...

We overview recent results concerning the symbolic veriication and calculation of siphons and traps for algebraic Petri nets and their relation to the net behavior.

Death statutes in the United States list elements of loss for which a defendent must make compensatory payment. The element that economists as expert witnesses are called upon to calculate is net income, roughly deÞned as the decedent’s income minus personal expenses. The existence of joint or shared consumption goods complicates the deÞnition and calculation of net income. Net income can be in...
