    A Brief Note on Wearable Sensors

    Zhihuan Luo

    Recently, wearable sensor technology has quickly moved from a largely science fiction vision to a wide range of established consumer and medical products. This explosion of wearable sensors is due to several factors, including the affordability and ergonomics of advances in miniaturized electronics, the proliferation of smartphones and connected devices, the growing desire of consumers to raise awareness about health, and the unmet need for clinicians to consistently obtain high-quality data caring for the health of your patients. Despite sizable preliminary successes, there's nevertheless a protracted manner to visit get even extra facts from the frame.

    Lasers in Cancer Treatment

    Kaibo Zheng

    Lasers are utilized to treat disease in more than one way. Their extreme focus light can be utilized to recoil or obliterate cancers or precancerous developments. Lasers are most regularly used to treat shallow tumors (diseases on the outer layer of the body or the coating of inside organs, for example, basal-cell skin malignant growth and the beginning phases of certain diseases, for example, cervical, penile, and vaginal, vulvar, and nonlittle cell lung cancer

      Optical Properties of MgO Thin Films Deposited on GeO2 and SiO2 Substrates

      Micheline Bejjani, Aicha Beya Far and Farid Flitti

      In this study, optical properties of magnesium oxide (MgO) thin film deposited on germania (GeO2) and silica (SiO2) were studied as a function of wavelength in the range 0.3-1.1µm using matlab. Refractive indices, extinction coefficients, and absorption coefficients were investigated. The transmittance spectra of MgO thin films of different thicknesses deposited on the different substrates were also examined. The films were found to show high transmittance and low absorbance in the visible and near infrared region. However, the absorbance of the film was found to be high in the ultraviolet. The effects of interference on transmission spectra were also considered. The results give good reason for the applications of MgO thin films in optoelectronic devices.

        The Effectiveness of High Intensity Laser Therapy (HILT) in the Treatment of Lateral Elbow Tendinopathy: A Systematic Review

        Dimitrios Stasinopoulos1,2*, Konstantinos Giannakou3 and Dimitrios Lamnisos3

        The aim of the present systematic review was to determine the effectiveness of High Intensity Laser Therapy (HILT) in the management of Lateral Elbow Tendinopathy (LET) and to provide recommendations based on this evidence. Methods: Randomized controlled trials (RCTs) identified by a search strategy in six databases were used in combination with reference checking. RCTs that included HILT, patients with LET, and at least one of the clinically relevant outcome measures were selected. A qualitative analysis of the selected studies was conducted using the Furlan system. Results: Three primary studies met eligibility criteria. All studies had a low risk of bias. There is no evidence for the effectiveness of HILT compared to bandage for the management of LET in the short-term. There is moderate evidence that HILT is more effective than LLLT for the management of LET in the short-term. Conclusion: HILT is a dose-response modality, and the optimal treatment dose has obviously not yet has been discovered. Further research with well-designed RCTs is required to provide meaningful evidence on the effectiveness (absolute and relative) of HILT for the management of LET.

          Optical Coherence Tomography (OCT) is an imaging strategy that utilizations low-soundness light to catch micrometer-goal, two-and three-dimensional pictures from inside optical dispersing media (e.g., natural tissue). It is utilized for clinical imaging and modern nondestructive testing (NDT). Optical intelligence tomography depends on low-lucidness interferometry, regularly utilizing close infrared light. The utilization of somewhat long frequency light permits it to enter into the dissipating medium. Confocal microscopy, another optical strategy, commonly infiltrates less profoundly into the example yet with higher goal.

          Channel Protection Schemes

          Dirk Salvia*

          A few plans have been exhibited to control the undesirable force journeys of enduring direct in EDFAs. These incorporate quick siphon control, interface control employing the addition of a remunerating sign, and gain clipping by an all-optical criticism circle. A large portion of these plans have zeroed in on accomplishing a shared objective: The greatest worth of the force journeys of the enduring channel ought to be not exactly a negligible part of a decibel for any conceivable change in channel stacking to limit the blunder blasts brought about by signal force drifters coming about because of a line disappointment or an organization reconfiguration. In this segment, we depict the beforehand referenced three plans to control the increase of the enhancer

            An Overview on Free-Electron Laser

            Kaibo Zheng

            A Free-Electron Laser (FEL) is a (fourth time) synchrotron light source making incredibly splendid and short beats of synchrotron radiation. A FEL capacities and acts from numerous points of view like a laser, yet rather than utilizing invigorated outflow from nuclear or sub-atomic excitations; it utilizes relativistic electrons as an addition medium. Synchrotron radiation is produced as a lot of electrons go through an attractive design (called undulator or wiggler). In a FEL, this radiation is moreover upgraded as the synchrotron radiation re-associates with the electron pack to such an extent that the electrons begin to produce soundly, accordingly permitting a dramatic expansion in general radiation force.

              Optimization and Comparison of Circular and Elliptical PCF for Generation of Slow Light in Optical Communication Using 2d FDTD Method

              Nilambar Muduli*, J.S.N Achary, Priya Sahu

              Effect on generation of a tunable slow rate light can be estimated by fabricating circular and elliptical PCFs. Choosing the background material to be As2Se3 Chalcogenide glass for their investigation. In addition, we have also measured the maximum allowed pump power for undistorted output pulse, Brillouin gain and time delay using same PCFs structure. It reports that, Brillouin.gain is found to be 87.2 dB/m for circular PCF(C-PCF), 90 dB/m for elliptical PCF (E-PCF) and time delay reaches to 138.64ns C-PCF, 142ns for EPCF.
              The above results seem to be measured using 1m long PCFs pumped with 100mW for both C-PCF and E-PCF. The simulating result of E-PCF is much more intensity for potential application in optical buffering, data synchronization, optical memories and signal processing etc over C-PCF.

                A Brief Note on the Quantum Gravity

                Claus Jacob

                Quantum Gravity (QG) is a field of speculative actual science that hopes to depict gravity as per the standards of quantum mechanics, and where quantum impacts can't be ignored, for example, nearby dark openings or comparative conservative astrophysical items, and where the impacts of gravity are solid, for example, neutron stars.
