1. Introduction. This is a fascinating paper on an important topic: the choice of predictor variables in large-scale linear models. A previous paper in these pages attacked the same problem using the " LARS " algorithm (Efron, Hastie, Johnstone and Tibshirani [3]); actually three algorithms including the Lasso as middle case. There are tantalizing similarities between the Dantzig Selector (DS) ...

Anti-reflection (AR) coating is an excellent spectacle lens option for increasing luminous transmission of the lens, reducing glare, and enhancing the cosmetic appearance of the wearer [4]. It is recommended for virtually all types of eyewear, including clear lenses for general, everyday use as well as nighttime driving; photochromic lenses for patients who frequently move between indoors and o...

in this paper we introduce and study besselian $g$-frames. we show that the kernel of associated synthesis operator for a besselian $g$-frame is finite dimensional. we also introduce $alpha$-dual of a $g$-frame and we get some results when we use the hilbert-schmidt norm for the members of a $g$-frame in a finite dimensional hilbert space.

Les motifs de migrations ne sont pas souvent investis par le cirque contemporain. Cependant nous avons pu suivre processus création la compagnie Sacorde pour spectacle K (sorti 7 octobre 2022 au festival Perplx à Courtai, Belgique). Avec cette nouvelle œuvre cirque, les trois acrobates ont voulu aborder thème des phénomènes migratoires sous prisme récits intimes, sentiments et souvenirs. En ret...

An implantable miniaturized telescope (IMT) for low vision has recently been developed. Surgically inserted into only one eye of patients with bilateral central visual loss, the IMT provides a nominal magnification of 3.0x and a field-of-view of 6.6 degrees (9.2 degrees for the 2.2x magnification version). Theoretical concerns have been raised regarding the ability of patients to function with ...

Methods | TheNational Eye Institute–funded Steroids for Corneal Ulcers Trial3,4 (SCUT) and the pilot study for the National Eye Institute–funded Mycotic Ulcer Treatment Trial2 (MUTT pilot) were concurrent, randomized controlled trials comparingoutcomes inpatientswithbacterial (SCUT)and fungal (MUTTpilot) keratitis. Detailedmethods have beenpreviously reported.2,3Outcomes for both trials include...

In the digital world, notions of intimacy, communion and sharing are increasingly enacted through new media technologies and social practices which emerge around them. These technologies with the ability to upload, download and disseminate content to select audiences or to a wider public provide opportunities for the creation of new forms of rituals which authenticate and diarise everyday exper...

In this thesis I examine the philosophical views of John Searle, Guy Debord, and Jean Baudrillard. These thinkers have radically different methodologies and theoretical alignments, but they are not entirely dissimilar. John Searle argues that there are two types of facts—those independent of human observation and those whose meaning depends on agreement. Guy Debord posits that modern society ha...

PURPOSE To evaluate whether visual target character and visibility affects spontaneous eye blink rate (SEBR) in primary eye gaze and silence. METHODS Video recordings were made of young healthy adults who were either emmetropic (n=32) or who wore spectacles for refractive error (range -4.75D and +4.50D (n=31). Emmetropes had 5min recordings made whilst seated and looking towards a distant whi...
