Low-Power Artificial Neural Network Perceptron Based on Monolayer MoS.

Machine learning and signal processing on the edge are poised to influence our everyday lives with devices that will learn and infer from data generated by smart sensors and other devices for the Internet of Things. The next leap toward ubiquitous electronics requires increased energy efficiency of processors for specialized data-driven applications. Here, we show how an in-memory processor fabricated using a two-dimensional materials platform can potentially outperform its silicon counterparts in both standard and nontraditional Von Neumann architectures for artificial neural networks.

The role of ultrasound biomicroscopy in the diagnosis of temporal arteritis.

Temporal artery biopsy is considered the gold standard for the diagnosis of temporal arteritis (TA). The aim of the study was to determine whether ultrasound biomicroscopy (UBM) findings are useful in predicting the result (positive or negative) of temporal artery biopsy in patients with TA. Sixteen consecutive patients (ten women and six men) with clinical diagnosis of TA seen at the Ophthalmology Unit, S.

Ultrasound biomicroscopic analysis of iris-fixed acrylic intraocular lens in the absence of capsule support.

The aim of the study was to investigate postoperative complications and to determine with ultrasound biomicroscopy (UBM) the position of a foldable acrylic intraocular lens (IOL) implanted with a surgical technique of iris suturing in eyes without capsule support. Six eyes with iris-sutured IOLs were examined postoperatively with UBM. The examination included the position of haptics and their relationship to the surrounding structures.

Severe proliferative diabetic retinopathy treated with vitrectomy or panretinal photocoagulation: a monocenter randomized controlled clinical trial.

Objective: Visual and anatomic results of pars plana vitrectomy were compared with panretinal photocoagulation in cases of severe proliferative diabetic retinopathy.

Design: Monocenter randomized controlled clinical trial; randomization and allocation to trial group were carried out by a central computer system.

Participants: We studied 180 eyes of 180 patients with severe proliferative diabetic retinopathy, half with tractional retinal detachment not involving the macula (n = 90).

Heavy versus standard silicone oil in the management of retinal detachment with macular hole in myopic eyes.

Purpose: The purpose of this study was to compare pars plana vitrectomy (PPV) with 1000 cSt silicone oil endotamponade and PPV with densiron endotamponade for retinal detachment with macular hole and posterior staphyloma in highly myopic eyes.

Patients And Methods: In a prospective study, 30 eyes of 30 patients were randomly assigned to PPV and densiron (n = 15) or PPV with silicone oil (n = 15). All eyes had laser photocoagulation of the macular hole rim after PPV.

Transconjunctival sutureless 25-gauge versus 20-gauge standard vitrectomy: correlation between corneal topography and ultrasound biomicroscopy measurements of sclerotomy sites.

Purpose: To determine the correlation between corneal shape changes and ultrasound biomicroscopy (UBM) findings at the sclerotomy sites in conventional 20-gauge (G) pars plana vitrectomy (PPV) and 25-G transconjunctival sutureless vitrectomy (TSV) and to compare the effectiveness of the two surgical methods.

Design: Prospective, comparative, observational case series.

Methods: Sixty consecutive eyes (60 patients) undergoing primary 3-port PPV.

Keratoconus staging: a computer-assisted ultrabiomicroscopic method compared with videokeratographic analysis.

Purpose: The aim of this study was to introduce a new paradigm for keratoconus assessment, the keratoconus index (KI), generated from the ratio of peripheral corneal thickness (PCT) to the thinnest corneal thickness (TCT), and calculated by a computer-assisted procedure after ultrabiomicroscope (UBM) examination. Then we compared KI and the keratoconus severity index (KSI), obtained by videokeratography in patients with different stages of keratoconus.

Methods: We studied 60 eyes with different forms of keratoconus using the TMS-3 autotopographer, provided with a keratoconus screening program (using Smolek-Klyce methods) and the commercial version of the ultrasound biomicroscope (Paradigm UBM Plus Model P45) equipped with a 50-MHz probe, which was provided with our computer-assisted program.
