Oled
OLED (organic light-emitting diode) is a light-emitting diode that uses organic compounds which emit light in response to an electric current. It consists of a cathode, an emissive layer, a conductive layer, and an anode, sandwiched between two electrodes. When voltage is applied, electrons flow to the emissive layer where they combine with holes to emit light. OLEDs have advantages over LCDs like being thinner, more flexible, requiring less power, and producing higher resolution and faster switching speeds. However, OLEDs also have shorter lifetimes and are more expensive than LCDs.
Cause and effect
The document explains the difference between a cause and an effect using the example of a boy being grounded for not being "on green" at school. It defines a cause as what happens first, and an effect as what happens second as a result of the cause. It identifies the boy not being "on green" at school as the cause and him being grounded as the effect. The document also provides signal words like "because" that help identify cause-effect relationships.
ozone
The Connection Between Ozone Layer Depletion and UVB Radiation
Reductions in stratospheric ozone levels will lead to higher levels of UVB reaching the Earth's surface. The sun's output of UVB does not change; rather, less ozone means less protection, and hence more UVB reaches the Earth. Studies have shown that in the Antarctic, the amount of UVB measured at the surface can double during the annual ozone hole.
Laser

Able to state the principle of population inversion
Able to explain the principle of semiconducting laser
Familiarise with the concept of light simulation and polarisation
Able to list down all materials criteria and materials selection for a given semiconducting laser compound.
Able to highlight several examples of the application of laser.
Leadership
This document discusses the key differences between managers and leaders. It defines leadership as influencing and guiding people, while noting there are different types of leaders defined by their position, personality, moral example, or power. Managers focus on processes and following rules, whereas leaders focus on inspiring people to achieve the right objectives. The document contrasts common management activities like planning, organizing, directing, and controlling work with the leadership approaches to each which emphasize strategy, communication, empowerment, and motivation.
Water cycle
Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet.
Motivation
The document discusses different types of human motivation, including primary motives related to basic needs like hunger, thirst, and sleep. It also covers general motives which are more about enhancing stimulation, and secondary motives which are learned drives including curiosity and manipulation. Additionally, it defines achievement drive as the desire to perform with excellence and be successful, and lists characteristics of high achievers such as taking moderate risks and preferring immediate feedback.
Air pollution
Stationary Sources include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices.

6. global warming
Carbon dioxide
combustion of solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products
Methane :
production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock.
Nitrous oxide
agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels.
Organic light emitting diodes
OLEDs (organic light-emitting diodes) operate similarly to traditional LEDs but use organic compounds rather than inorganic semiconductor materials. Excitons form when electrons and holes combine in the emissive layer. These excitons can then transfer their energy to fluorescent or phosphorescent molecules attached to polymers, causing the molecules to emit light as they return to the ground state. This indirect light emission mechanism greatly increases the probability of light being generated per exciton. OLEDs have advantages over traditional displays in being thinner, more flexible, and easier to fabricate due to the soft organic materials used. Research continues to improve OLED efficiency and develop new materials.
Nokia Morph
The Nokia Morph is built-in solar absorption might charge a device, whilst batteries become smaller longer lasting and faster to charge.
Data Communication
Communications involve the exchange of data between two devices via transmission. There are protocols with rules that govern message transmission through a medium to be received. For effective communication, a system must deliver data to the correct destination accurately and in a timely manner without delay or jitter in packet arrival times. Communication systems can operate in simplex, half-duplex, or duplex modes depending on whether transmission is one-way, two-way but alternating, or two-way concurrently, respectively.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
