Development of manufacture trend for TFTs technologies has focused on improving electrical properties of films with the cost reduction to achieve commercialization. To achieve this goal, high-performance sub-50 nm TFTs-based MOSFETs with ON-current (Ion)/subthreshold swing (S.S.) of 181 µA/µm/107 mV/dec and 188 µA/µm/98 mV/dec for NMOSFETs and PMOSFETs in a monolithic 3D circuit were demonstrated by a low power with low thermal budget process. In addition, a stackable static random access memory (SRAM) integrated with TFTs-based MOSFET with static noise margins (SNM) equals to 390 mV at VDD = 1...

BACKGROUND AND OBJECTIVE: The authors compare low fluence photodynamic therapy (PDT) against graded subthreshold transpupillary thermotherapy (TTT) for chronic central serous chorioretinopathy (CSC). PATIENTS AND METHODS: Forty-two eyes of 42 patients with chronic CSC were included in this prospective, nonrandomized, interventional trial. All patients were offered PDT as an initial intervention. If they declined PDT, TTT was offered. RESULTS: Twenty patients underwent PDT and 22 underwent TTT...

We report the first monolithic integration of InGaAs channel field-effect transistors with InGaAs/GaAs multiple quantum wells (MQWs) lasers on a common platform, achieving a milestone in the path of enabling low power and high speed opto-electronic integrated circuits (OEICs). The III-V layers used for realizing transistors and lasers were grown epitaxially on the Ge substrate using molecular beam epitaxy (MBE). A Si-CMOS compatible process was developed to realize InGaAs n-FETs with subthreshold swing SS of 93 mV/decade, I<sub>ON</sub>/I<sub>OFF</sub> ratio of more than 4 orders of magnitude with very low off-state leakage current, and a peak effective mobility of more than 2000 cm<sup>2</sup>/V·s...

Objectiv. To evaluate the efficacy of subthreshold micropulse yellow (577 nm) laser photocoagulation in diffuse macular edema (DME) in rural and urban patients of south-eastern Poland. MATERIALS AND METHOD: Seventy-five eyes of 75 patients with diffuse DME were treated with subthreshold micropulse yellow laser photocoagulation with a 5% duty cycle at an energy level. The laser exposure time was 20 ms and the spot diameter was 100 μm. Best corrected visual acuity (BCVA), reading vision (Snellen) and optical coherence tomography-determined central retinal thickness (CRT) were estimated before and 2, 4 and 6 months after laser treatment...

REVIEW
Daniel Su, Jean-Pierre Hubschman
The role of retinal photocoagulation as a first line therapy for various retinal pathologies has decreased with the introduction of anti-vascular endothelial growth factor therapy. However, retinal laser therapy remains an important treatment modality, especially with the emergence of micropulse subthreshold treatment and the integration of newer technology such as augmented reality and semi-automated delivery. This review summarizes current evidence for micropulse laser as a treatment modality and discusses the role of new technology such as augmented reality in the future of laser therapy...

PURPOSE: To evaluate the effects of the subthreshold laser treatment as a therapeutic option in the treatment of serous retinal detachment secondary to dome-shaped macula. METHODS: Prospective pilot study with 12-month follow-up. Each patient underwent a complete ophthalmologic examination, including best-corrected visual acuity, fluorescein angiography, indocyanine green angiography, and spectral domain optical coherence tomography. Eyes with persistent serous retinal detachment lasting for a minimum of 12 months and absence of best-corrected visual acuity improvement underwent subthreshold laser treatment in a single session...

External control over rapid and precise release of chemicals in the brain potentially provides a powerful interface with neural activity. Optical manipulation techniques, such as optogenetics and caged compounds, enable remote control of neural activity and behavior with fine spatiotemporal resolution. However, these methods are limited to chemicals that are naturally present in the brain or chemically suitable for caging. Here, we demonstrate the ability to interface with neural functioning via a wide range of neurochemicals released by stimulating loaded liposomal nanostructures with femtosecond lasers...

Purpose. To compare the efficacy and safety of subthreshold micropulse yellow wavelength laser (SMYL) and low-fluence photodynamic therapy (PDT) in the treatment of chronic central serous chorioretinopathy (CSC). Methods. Thirty-three eyes of 30 patients with chronic CSC received either PDT (18 eyes) or SMYL (15 eyes) therapy. Best corrected visual acuity (BCVA), subretinal fluid (SRF) height, and central macular thickness (CMT) were evaluated at the baseline visit and one, three, six, nine, and 12 months after the therapy...

Patterns formed by the laser direct writing (LDW) lithography process are used either as channels or barriers for MoS2 transistors fabricated via inkjet printing. Silver (Ag) nanoparticle ink is printed over patterns formed on top of the MoS2 flakes in order to construct high-resolution source/drain (S/D) electrodes. When positive photoresist is used, the produced grooves are filled with inkjetted Ag ink by capillary forces. On the other hand, in the case of negative photoresist, convex barrier-like patterns are written on the MoS2 flakes and patterns, dividing the printed Ag ink into the S/D electrodes by self-alignment...

Purpose. To compare the efficacy of subthreshold and conventional selective laser trabeculoplasty (SLT) in lowering intraocular pressure (IOP) in the patients with primary open-angle glaucoma (POAG). Methods. Fifty-two eyes from fifty-two POAG patients were randomized into two groups, one group treated with subthreshold SLT using two-thirds of the conventional energy and the other one treated with the conventional energy. IOP was measured with the Goldmann tonometer and the anterior chamber inflammation was determined using laser flare meter...

REVIEW

Diabetic macular oedema, characterised by exudative fluid accumulation in the macula, is the most common form of sight-threatening retinopathy in people with diabetes. It affects one in 15 people with diabetes resulting in more than 20 million cases worldwide. Few epidemiological studies have been done to specifically investigate risk factors for diabetic macular oedema, although poor glycaemic and blood pressure control are associated with the presence and development of the disorder. The pathophysiological processes begin with chronic hyperglycaemia, and interplay between vascular endothelial growth factor (VEGF) and inflammatory mediators...

PURPOSE: To evaluate the outcomes of transscleral diode laser photocoagulation in the eyes of children with a history of threshold retinopathy of prematurity (ROP) and compare them with the eyes of children with no or subthreshold ROP and normal term infants by spectral-domain optical coherence tomography (SD-OCT). METHODS: Three groups of children aged 4 to 10 years were included as follows: 45 patients with regressed ROP who had not received any treatment (group 1), 48 patients with a history of zone 2 threshold ROP who had been treated with transscleral diode laser (group 2), and 56 age-matched healthy full-term children (group 3)...

Many clinical trials have demonstrated the effectiveness of subthreshold phototherapy with no visible damage in retinal vascular diseases, such as diabetic retinopathy. We aimed primarily to investigate the effect of subthreshold diode micropulse laser (SDM) treatment on mouse retinal pigmented epithelium (RPE) cells. The expression of angiogenesis-modulating cytokines in response to SDM was also explored. The least toxic laser dose was selected by measuring cell viability with MTT assay and 5 % duty cycle (DC) was chosen for use in further experiments...
