A system of add/drop can be used as an interferometer system to generate nano bandwidth of optical tweezers. Dark soliton-Gaussian control within the proposed system is analyzed. Optical tweezers have the unique ability to trap and manipulate particles at the mesoscopic scale. The proposed system can be applied to generate nano-sized bandwidth peaks of optical tweezers in the form of potential wells. The dynamic behavior of the tweezers occurred when the Gaussian laser pulse is added into the system. Here, tweezers with Full Width at Half Maximum (FWHM) of 12 nm could be generated. This technique is applicable for cellular surgery due to the precise setting and small diameter of the nano tweezers. Therefore, the interaction of the nano tweezers with injected gold nano particles contributes to transferring of heat to the abnormal cells leads to removal surgery process, thus tweezers can be used to selectively eliminate cellular components in individual cells.

Palkansaajien tutkimuslaitoksen talousennusteen mukaan Suomi vajoaa jyrkästi taantumaan. Kokonaistuotanto supistuu tänä vuonna 3,7 prosenttia ja ensi vuonnakin vajaan prosentin. Suurin yksittäinen syy tuotannon laskuun on viennin määrän väheneminen liki 10 prosentilla tänä vuonna, mutta myös yksityisten investointien noin 10 prosentin putoaminen on merkittävä. Ensi vuonna vienti ja investoinnit supistuvat edelleen jonkin verran. Yksityinen kulutus polkee lähes paikallaan, ja hallituksen elvytystoimet jäävät tehottomiksi. Tänä vuonna työttömyysaste nousee 7,4 prosenttiin ja ensi vuonna jo 8,8 prosenttiin. Työllisyys heikkenee kahdessa vuodessa 100 000 hengellä. Kuluttajainflaatio hidastuu selvästi, noin 1,4 prosentin tasolle.

In this paper, a novel system of simultaneous optical logic AND and OR gates using dark -bright soliton conversion within the add/drop optical filter system is proposed. The input logic „0‟ and control logic „0‟ are formed by using the dark soliton pulse (D) trains. By using the dark-bright soliton conversion behavior within the π/2 phase shift device, we found that the simultaneous optical logic AND and OR gates at the drop and through ports can be randomly formed, respectively.

A novel system of multisoliton generation using nonlinear equations of the propagating signals is presented. This system uses a PANDA ring resonator incorporated with an add/drop filter system. Using resonant conditions, the intense optical fields known as multisolitons can be generated and propagated within a Kerr-type nonlinear medium. The present simulation results show that multisolitons can be controlled by using additional Gaussian pulses input into the add port of the PANDA system. For the soliton pulse in the microring device, a balance should be achieved between dispersion and nonlinear lengths. Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system. Chaotic signals can be filtered by using the add/drop filter system, in which multi dark and bright solitons can be generated. In this work multi dark and bright solitons with an FWHM and an FSR of 425pm and 1.145 nm are generated, respectively, where the Gaussian pulse with a central wavelength of 1.55 μm and power of 600 mW is input into the system.

A system of microring resonator (MRR) is presented to generate extremely narrow optical tweezers. An add/drop filter system consisting of one centered ring and one smaller ring on the left side can be used to generate extremely narrow pulse of optical tweezers. Optical tweezers generated by the dark-Gaussian behavior propagate via the MRRs system, where the input Gaussian pulse controls the output signal at the drop port of the system. Here the output optical tweezers can be connected to a quantum signal processing system (receiver), where it can be used to generate high capacity quantum codes within series of MRR’s and an add/drop filter. Detection of the encoded signals known as quantum bits can be done by the receiver unit system. Generated entangled photon pair propagates via an optical communication link. Here, the result of optical tweezers with full width at half maximum (FWHM) of 0.3 nm, 0.8 nm and 1.6 nm, 1.3 nm are obtained at the through and drop ports of the system respectively. These results used to be transmitted through a quantum signal processor via an optical computer network communication link.

We propose a system of microring resonators (MRRs) incorporating with an add/drop filter system. Optical soliton can be simulated and used to generate entangled photon, applicable in single and multiple optical switching. Chaotic signals can be generated via the MRRs system. Therefore continuous spatial and temporal signals are generated spreading over the spectrum. Polarized photons are formed incorporating the polarization control unit into the MRRs, which allows different time slot entangled photons to be randomly formed. Results show the single soliton pulse of 0.7 ps where the multi soliton pulse with FSR and FWHM of 0.6 ns and 20 ps are generated using the add/drop filter system. Here Ultra-short single soliton pulse with FWHM=42 fs can be simulated. These pulses are providing required communication signals to generate pair of polarization entangled photons among different time frame where the polarization control unit and polarizer beam splitter (PBS) are connected to the ring resonator system.

We suggest a new purpose of a security scheme by employing the nonlinear behaviors of temporal dark and bright solitons amongst a micro-ring resonator system for signal security application. The chaotic signal is generated, where the required bright soliton pulse can be recovered and discovered by an add/drop filtering device. By using the reserve ring parameters, simulation results obtained have demonstrated that the soliton conversion can be performed. In application, the chaotic signal is generated and formed by the dark soliton inside a nonlinear micro-ring device. The different temporal soliton response time can be seen, the response times of 169 and 84 ns are mentioned for temporal dark and bright solitons, respectively, which can also be used to figure the security key. The technique of optical conversion can be use to improve the optical communication network systems.

In this study an interesting system in which a bright and dark soliton pulse can be stopped inside a nonlinear waveguide is presented. Here, we propose a system consisting of a series of ring resonators for optical trapping within a nonlinear waveguide. The bright and dark solitons can be controlled and slowed down within the waveguide. The FWHM for the output signals are calculated and used as an optical memory. Bright and dark soliton behaviors within a micro and nano ring resonator are also investigated and described. The required pulse is filtered and amplified, can be controlled and localized within the system. The localized bright and dark solitons are stopped by controlling the input power,which means that the photon stopping can be controlled by light in a ring resonator.

This research is used to control the nonlinear behavior of silicon microring resonators, MRR’s such as chaos and bifurcation. Increasing of nonlinear refractive indices, coupling coefficients and radius of the SMRR leads to descend input power and round trips wherein the bifurcation occurs. As result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n2=3.2×10−20 m2/W. Smallest round trips can be seen for the R=40 µm and  0.1 respectively. Signals from the SMRR are passing through a polarizer beam splitter to generate quantum binary codes which are used in wireless network communication.

Generation of picometer optical soliton pulses is investigated using a nonlinear PANDA ring resonator system connecting to an add/drop filter system. The objectives of the research are to employ systems of microring resonator (MRR) to generate binary signals to be carried out along fiber optic communication. Effective parameters such as refractive indices of a silicon waveguide, coupling coefficients (), coupling loss, radius of the ring (R) and the input power can be selected properly to operate the nonlinear behavior. The input Gaussian laser pulses with power of 600 mW are inserted into the system. The central wavelength of the input power has been selected to λ0=1.55 µm where the nonlinear refractive index of the medium is n2=2.6×10−17 m2 W−1. Therefore binary signals generated by the add/drop filter system can be converted to secure codes where the decoding process of the transmitted codes can be obtained at the final step. Here, multi soliton pulses with full width at half maximum (FWHM) of 325 could be generated, converted to secure codes and finally detected over 70 km optical fiber communication link.

In this paper, we propose a system for chaotic signal generation using a microring resonator (MRR) fiber optic system. This system uses a regular laserdiode as input power and can be incorporated with an optical add/drop filter system. When light from the laser diode feedbacks to the fiber ring resonator, the actual chaotic signal is produced by using the appropriate fiber ring resonator parameters and also the laser diode input power. The filtering process of the chaotic signals occurs during the round-trip of the pulse within the ring resonators. The single soliton pulses generation and bandwidth manipulation of the pulse can be performed using the add/drop system. Results obtained have established particular possibilities from the application. The obtained results show the effects of coupling coefficients on the bandwidth of the single soliton pulse, where the chaotic behaviors of the input pulses are presented.

The nonlinear behavior (chaotic) of light traveling in an optical fiber ring resonator such as an add/drop system is presented. The chaotic behavior is considered to be a beneficial effect that can be used in the communication system. Such a system can be used to secure the information signals, therefore, the ability of chaotic carriers to synchronize in a communication system is performed. The used optical material is InGaAsP/InP regarding to suitable parameters of the system. The nonlinear refractive index is fixed to n2 = 3.8 × 10−20 m2 /W, and the 20,000 iterations of round-trip within the system is simulated. The input powers are selected at 1 W, where the coupling coefficient of the system varies according to two critical cases, where 0    0.1 and 0.1  1. As a results, larger coupler coefficient corresponds to lower input power for the case of 0    0.1 and smaller coupling coefficient of the system is corresponds to lower input power when 0.1  1. To optimize the microring systems, Lower input power is recommended in many applications in optical optical communication systems.

POGONATUM : morphology, anatomy, reproduction etc.

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.

www.seribangash.com The Mariana Trench is one of the most remarkable geological features on Earth. Here are some details about it: Location: The Mariana Trench is located in the western Pacific Ocean, east of the Mariana Islands. It stretches for about 2,550 kilometers (1,580 miles) and is known as the deepest part of the world's oceans. Depth: The trench reaches incredible depths, with its deepest point known as the Challenger Deep, which plunges down to approximately 10,984 meters (36,037 feet) below sea level. To put this into perspective, if Mount Everest, the tallest mountain on Earth, were placed at the bottom of the Challenger Deep, its peak would still be over 2 kilometers (1.25 miles) underwater. Formation: The Mariana Trench was formed by the subduction of the Pacific Plate beneath the Mariana Plate. This process creates a deep trench as the heavier Pacific Plate is forced beneath the lighter Mariana Plate. Geological Features: The trench is characterized by steep, V-shaped valleys, and its walls are composed of highly compressed sedimentary rock. At the bottom of the trench, there are also large amounts of marine sediment. Pressure: The pressure at the bottom of the Mariana Trench is immense, reaching over 1,000 times the pressure at the surface. This extreme pressure creates a challenging environment for exploration and makes it difficult for organisms to survive. Exploration: Despite its extreme conditions, the Mariana Trench has been the subject of numerous scientific expeditions and explorations. One of the most famous explorations was the dive to the Challenger Deep by Swiss scientist Jacques Piccard and U.S. Navy Lieutenant Don Walsh in 1960. More recently, in 2012, filmmaker James Cameron made a solo dive to the bottom of the Challenger Deep in the Deepsea Challenger submersible. Biological Discoveries: Despite the harsh conditions, the Mariana Trench is home to a surprising variety of life forms, including unique species of deep-sea fish, crustaceans, and microbial life. Some organisms have adapted to survive in the extreme pressure and darkness of the trench. Environmental Importance: Studying the Mariana Trench provides valuable insights into the geology, biology, and oceanography of the deep sea. It also helps scientists better understand the processes that shape the Earth's crust and the distribution of life in the oceans. Conservation: Due to its remote location and extreme depths, the Mariana Trench has remained relatively untouched by human activity. However, there is growing concern about the potential impacts of deep-sea mining and pollution on this fragile ecosystem, highlighting the need for conservation efforts to protect this unique environment. https://seribangash.com/barber-shop-business-complete-guide-for-beginners/ https://seribangash.com/legend-virat-kohli-in-cricket-history/

Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans. Motivated by recent JWST observations of K2-18 b, we self-consistently model the photochemistry and potential detectability of biogenic sulfur gases in the atmospheres of temperate sub-Neptune waterworlds for the first time. On Earth today, organic sulfur compounds produced by marine biota are rapidly destroyed by photochemical processes before they can accumulate to significant levels. Domagal-Goldman et al. suggest that detectable biogenic sulfur signatures could emerge in Archean-like atmospheres with higher biological production or low UV flux. In this study, we explore biogenic sulfur across a wide range of biological fluxes and stellar UV environments. Critically, the main photochemical sinks are absent on the nightside of tidally locked planets. To address this, we further perform experiments with a 3D general circulation model and a 2D photochemical model (VULCAN 2D) to simulate the global distribution of biogenic gases to investigate their terminator concentrations as seen via transmission spectroscopy. Our models indicate that biogenic sulfur gases can rise to potentially detectable levels on hydrogen-rich water worlds, but only for enhanced global biosulfur flux (20 times modern Earth’s flux). We find that it is challenging to identify DMS at 3.4 μm where it strongly overlaps with CH4, whereas it is more plausible to detect DMS and companion byproducts, ethylene (C2H4) and ethane (C2H6), in the mid-infrared between 9 and 13 μm.
