Meta-analyses were performed for the mean change in intraocular pressure (IOP) at one-month, six-month, and one-year follow-up visits, rate of IOP spikes (> 5 mmHg increase from the pre-procedure baseline IOP), rate of treatment failure (< 20% or < 3 mmHg reduction in IOP or requiring additional medications or procedures), and mean change in number of medications.Results: Six studies, with a total of 593 eyes, were included: 283 underwent MLT, while 310 underwent SLT. A statistically significant difference in the efficacy of MLT versus SLT at one-month and six-month follow-ups was present, with SLT reducing IOP by 0.83 mmHg (95% CI: 0.20, 1.47; P = 0.01) more and 0.55 mmHg (95% CI: 0.02, 1.08; P = 0.04) more than MLT, respectively. At the one-year follow-up, there was no significant disparity in IOP reduction between SLT and MLT (WMD = 0.16; 95% CI: − 0.40, 0.71; P = 0.58). There was a significantly lower rate of IOP spikes in the MLT treatment group (RR = 0.37; 95% CI: 0.16, 0.89; P = 0.03). There was no statistically significant difference in the rate of treatment failures (RR = 1.05; 95% CI: 0.68, 1.62; P = 0.84) or number of topical medications reduced (WMD = 0.06; 95% CI: − 0.13, 0.26; P = 0.53).Conclusion: While SLT may offer greater short-term reductions in IOP, it may be associated with more postoperative IOP spikes when compared to MLT. At one-year follow-up, there were no significant differences in IOP reduction or failure rates between the MLT and SLT groups.Keywords: trabeculoplasty, micropulse, SLT, selective laser trabeculoplasty, glaucoma

Two-dimensional van der Waals ferroelectric materials play an important role in a wide spectrum of semiconductor technologies and device applications. Integration of ferroelectrics into 2D-layered material-based devices is expected to offer intriguing working principles and add desired functionalities for next-generation electronics. Here, we investigate the electric and thermoelectric properties of thin layers of the 2H and 3R polymorphs of α -In2Se3 embedded in solid-state three-terminal devices. Charge transport measurements reveal a hysteretic behavior that can be ascribed to the effect of ferroelectric polarization at the metal electrode/2D semiconductor interfaces. The thermoelectric investigation of the same devices unveils a well-defined negative signal of the order of 100–200 μ V/K in absolute value for the 2H polymorph, showing a slight modulation as a function of the gate voltage. An analogous but noisy thermoelectric voltage is measured for devices based on the 3R polymorph, where indeed a constant finite transversal offset in the 100 μ V-few mV range is detected, which does not depend on the applied temperature gradient. We argue that these experimental observations are related to a strong residual in-plane ferroelectric polarization in the 3R α -In2Se3 polymorph thin layer. Our results show that the thermoelectric response is a fine probe of the ferroelectric character of 2D layered α -In2Se3. [ABSTRACT FROM AUTHOR]

The measurement based on the vision of periodic patterns by a remote camera is a more suitable solution for the control and characterization of micro robotic systems. In this way, we can take precise measurements without disturbing the measured objects and without the need for more devices and sensors that cause great confusion and clutter around the workspace. The technique of projection of the coded periodic patterns is perhaps effective and of good performance and especially in the case of a well calibrated system. Indeed, the question arises on the influence of the calibration on the results of measurement by this technique in terms of precision and uncertainty. Thus, the main purpose of this article is to study the influence of calibration on the measurement process, by deducing and calculating the committed error and the uncertainty rate. Based on an algorithm in MATLAB, we first create a coded periodic test pattern to which we apply a certain imposed displacement. Then, we project this pattern using a projection and reduction system on a digital camera which captures a photo and transmits it to a processing algorithm, which, in turn, calculates and deduces a value for the measured displacement. The repetition of this process occurs several times on the same imposed displacement (the same standard) to provide us with several measured values, this redundancy of the data allows us to draw a calibration curve and deduce several metrological parameters from our system of measure.
