@HymnStitched @CreepinOG Quantum dot (QD) photobleaching is the phenomenon where a QD loses its fluorescence intensity over time when exposed to light Infrared measurements are crucial for determining sea surface temperature (SST). Satellites equipped with infrared radiometers, like the ISAR instrument, measure the upwelling infrared radiation emitted from the ocean surface. This allows for the measurement of SST, including the sea surface skin temperature (SSTskin), which is the temperature of the uppermost layer of water, typically 10-20 micrometers deep

Body free radical balance refers to the equilibrium between the production of free radicals and the body's ability to neutralize them using antioxidants. A healthy body maintains this balance, preventing excessive free radical activity, which can lead to oxidative stress and cellular damage. @NtwesSc Be ye therefore perfect, even as your Father which is in heaven is perfect.

Image Whispering gallery mode (WGM) resonators, like microdiscs and microspheres, are optical devices that trap light within a cavity by total internal reflection, causing light to travel along the surface of the resonator. Microspheres, the simplest 3D WGM resonators, exhibit high quality factors (Q), leading to high energy density, narrow resonant wavelengths, and long cavity ringdown. Microdiscs, a 2D version, also demonstrate WGMs and are used in applications like microlasers and optical switches. 

Key Features of WGM Microresonators:
•High Q-factor: WGM resonators exhibit exceptionally high Q-factors (10^8 - 10^9), meaning light is trapped for extended periods. 

•Narrow Resonant Lines: The high Q-factor results in narrow, distinct resonant wavelengths. 

•High Energy Density: The confined light leads to high energy density within the resonator. 

•Total Internal Reflection: Light is trapped within the resonator by total internal reflection, causing it to travel along the surface. 

•Sensitivity to Changes in the Surroundings: WGMs are highly sensitive to changes in the refractive index of the surrounding medium, making them suitable for sensing applications. 

Microdisc vs. Microsphere:
•Geometry:
Microdiscs are flat, 2D structures, while microspheres are 3D spheres. 





•Applications:
Both can be used for sensing, filtering, and lasing, but microdiscs are more suitable for integrated optical systems due to their planar nature. 





•Fabrication:
Microspheres can be fabricated using various techniques, including self-assembly of π-conjugated alternating copolymers, as shown in. 





•Benefits:
Microspheres offer a simple 3D resonator structure, while microdiscs can be easily integrated into micro-optical devices. 





Applications:
•Sensing:
WGMs are used in biosensors for protein adsorption, trace gas detection, and other applications due to their sensitivity to changes in the refractive index. 





•Lasing:
WGMs can be used to create micro-lasers, where light is confined and amplified within the resonator. 





•Filtering:
WGMs can act as wavelength filters, selecting specific wavelengths of light. 





•Optical Switching:
WGMs can be used to create optical switches, allowing for switching between different optical paths.

•Qubit in "On" State:
When the qubit is in the "on" state, it is interacting with the ring resonator, allowing for the exchange of energy and the establishment of quantum correlations between qubits. This is crucial for performing quantum computations and entangling multiple qubits. 





•Qubit in "Off" State:
When the qubit is in the "off" state, it is not actively interacting with the resonator, meaning it is not involved in the current quantum operation. This allows for the qubit to be prepared in a specific state or measured without interference from the resonator. In the context of quantum computing and specifically regarding qubits in a ring resonator, "on" and "off" refer to the state of the qubit, meaning whether it is actively interacting with the resonator and undergoing quantum operations or not. The qubit can be toggled between these states to implement two-qubit gates and other quantum algorithms.

In trapped-ion quantum computing, individual ions are used as qubits, where the qubit state (0 or 1) is represented by two distinct energy levels within the ion, such as two hyperfine levels or an optical ground and excited state. The "SPN state" you're likely referring to is a specific qubit state, often represented as |0⟩ or |1⟩, and can also be in a superposition of both states. The "charge" of the ion is the electrical charge it carries, which is essential for trapping and manipulating it using electromagnetic fields. Ions of the Ionosphere

Beam steering is a technique used to redirect or change the direction of a beam, such as an electromagnetic wave, optical beam, or even a particle beam, without physically moving the source of the beam. This is typically achieved by manipulating the beam's properties, like its phase or frequency, or by using multiple elements in an array to constructively or destructively interfere with the beam What it is: 

•Beam steering involves controlling the direction of a beam, whether it's light, radio waves, or other types of beams.
•It allows for directing the beam to a specific location or direction without physically moving the source.
2. How it's done:
•Phased Array Antennas:
In radio and radar systems, beam steering can be achieved by changing the relative phases of the signals driving individual antenna elements in an array. 




•Optical Beam Steering:
In optics, this can be done using mirrors, lenses, or even devices that manipulate the beam's properties like wavelength or phase. 




•Ultrasound:
In medical imaging, beam steering in ultrasound involves altering the angle of the beam with respect to the transducer, allowing for multiple angles of insonation from a single probe position. 




3. Applications:
•Radar and Radio:
Beam steering is crucial for radar systems to scan a wide area or to track moving targets, and for radio communication to focus signals on specific receivers. 




•Optics:
It's used in applications like laser scanning, optical communication, and LiDAR (Light Detection and Ranging). 




•Ultrasound:
It's used in ultrasound imaging to improve image quality and reduce speckle. 




•Acoustics:
Beam steering can also be used in sound systems to direct sound to specific areas and reduce reflections

Vortex beam carrying orbital angular momentum (OAM) attracts much attention in many research fields for its special phase and intensity distributions. In this Letter, a novel design called the spiral phase microsphere (SPMS) is proposed for the first time, to the best of our knowledge, which can convert incident plane wave light into the focused vortex beam that carries OAM with different topological charges and . Applications and development of orbital angular momentum (OAM) beams. The distinctive light field distribution of OAM beams enables a broad spectrum of applications, with the number of topological charges (TCs) playing a crucial role. Image

While both volcanic eruptions and nuclear explosions are powerful events, some volcanic eruptions can release significantly more energy than even the most powerful nuclear weapons… just saying. I am starting to think history is repeating itself… especially now that I understand Israel has a nuclear bomb and wants to keep it confidential for certain reasons.

Israel and the U.S. signed a free trade agreement 40 years ago and around 98% of goods from the U.S. are now tax-free. The UK became legally able to independently negotiate trade agreements when it left the European Union from 1 January 2020 due to a transition period which lasted until the UK formally exited the EU.[2] Negotiations opened in May 2020, but have stagnated since 2021 under the Biden Administration which has focused on fixing its domestic economy.
