The large piezoelectric coefficients and high-quality factors of single crystal LiNbO3 have been exploited to enable high coupling torsional actuation. The fabricated actuator has a mirror size of $22\mathrm{x}40\ \mu \mathrm{m}^{2}$, and quality factors of 547 and 1497 in air and vacuum respectively. Moreover, the optical angle can exceed $31^{\circ}\ (\theta_{opt}= 4\cdot\theta_{mech})$ in both air and vacuum, leading to an FoM surpassing state-of-the-art high-frequency scanners. Our demonstration has shown great potential for scanning micro-mirrors, and light detection and ranging systems (LIDAR) applications where frequency scalability, scanning angles, and footprint are the main challenges.

The proposed organic materials as an active material are PCPDTBT(Poly[2,1,3-benzothiadiazole-4,7-diyl[4,4-bis(2ethyl-hexyl)-4H-cyclopenta[2,1-b:3,4 b']dithiophene2,6diyl]]), P3HT (Poly(3-hexylthiophene 2,5-diyl)) and PC61BM ([6,6]-Phenyl-C61-butyric acid methyl ester) because of their non-linear optical properties, easy fabrication techniques and low cost. Transparent Conducting Oxides (TCOs) are used in photovoltaics and optical devices for its low electrical resistance. In addition, TCOs do not have many losses for propagated light. The metric for the comparative study between materials is the insertion losses for a 500 nm wavelength source along with these materials. The material that has better performance should have a low insertion loss. In this paper, a study was conducted on the behavior of acceptors concentration, Shockley-Read-Hall (SRH) recombination, I-V, and P-V characteristics on a 1D Si P-N junction. The numerical solutions for insertion losses and 1D Si P-N junction are carried out by LUMERICAL and COMSOL software, respectively. At a depth of 100 nm, PC61BM has a better performance over PCPDTBT and P3HT with Insertion losses (IL) of 3.07 dB and 2.76 dB for TE and TM mode, respectively. For TCOs materials. The behavior of insertion losses on Indium Tin Oxide (ITO), Gallium doped Zinc Oxide (GZO), and Aluminum doped Zinc Oxide (AZO) is traced. At a depth of 100 nm, the insertion losses are minimized by AZO and ITO with a magnitude of 1.91 dB and 1.87 dB for TE mode, respectively, while 1.45 dB for TM mode.

The model incorporates the effects of fermi weak neutrinos in the magnetized plasma. The resulting Neutrino-Magnetohydrodynamic model was investigated for parallel, perpendicular and oblique propagation of wave. A fast neutrino driven short wavelength instability is found (associated with magnetoionic wave). The instability is derived in context of supernova parameters. The present works incorporates the arbitrary direction of wave propagation, and fast and slow magnetohydrodynamic wave (MHD) and intermediate case of oblique angle. Also, in case of non-linear or high frequency wave, the neutrino coupling breaks the frozen in flux condition even in infinite conductivity plasma.

Group III: 5% NaOCl at RT during instrumentation, while the final rinse was 20 mL of 5% cold NaOCl (2°C–5°C). Group IV: 5% NaOCl at RT during instrumentation followed by 20 mL of cold saline (2°C–5°C). Postoperative pain score was recorded using a modified visual analog scale at 12, 24, 48, and 72 h and after 1 week. Paper point...

Group II; 5% coldsodium hypochlorite (2-5°C). Group III; final rinse with 20 mL of 5% cold sodiumhypochlorite (2-5°C) for 5 minutes. Group IV; final rinse with 20 mL of cold saline (2-5°C) for 5 minutes. Paper point passing 2 mm beyond the apex was used to collect periapicalfluid before, immediately after mechanical instrumentation and after one week tocharacterize the mRNA expression of IL-1β and Il-10 using real-time polymerase chainreaction (PCR). Statistical analysis was performed using one-way ANOVA to comparebetween all groups. Results: Our results revealed statistically significant (at P≤ 0.05)do...

A combination of P3HT: PCBM with parallel vertical LiF cylinders formulate the active material structure. The collection efficiency in the active material reaches 92.2%. The operating wavelength where the maximum collection efficiency occurs is adjusted and matched with the wavelength where the maximum irradiance of the solar spectrum occurs. The absorption per unit volume of the new structure is 80.4 µm−3 while the blank structure is 75.07 µm−3. The net absorption magnitude for the required structure is 32.09. The LiF is considered a suitable material for the vertical cylinders in the proposed structure. At a depth of 95 nm and operating wavelength 500 nm, for TE mode, LiF has the highest insertion losses with 0.7 dB. However, ITO and ZnO possess 0.35 dB and 0.49 dB, respectively. For TM mode, LiF has the lowest insertion losses at the same depth with 0.7 dB, while ZnO possesses 0.49 ...

Hence, this study was aimed to evaluate the effect of intracanal cryotherapy on postendodontic pain and interleukin-6 (IL-6) expression in teeth with symptomatic apical periodontitis. Materials and Methods: Forty-eight single-rooted teeth in patients with symptomatic apical periodontitis were randomly divided into four groups based on the irrigation protocol. Group I (control): 5% sodium hypochlorite (NaOCl) at room temperature (RT) was used during instrumentation and final rinse. Group II: 5% cold NaOCl (2°C–5°C) was used during the root canal procedure. Group III: 5% NaOCl at RT during instrumentation, while the final rinse was 20 mL of 5% cold NaOCl (2°C–5°C).
