A Spectral Symphony: Demystifying the Hidden World of Radiation Pollution
Beneath the vibrant tapestry of life lurks a silent threat, an invisible melody woven from the very fabric of energy itself. This is the domain of radiation pollution, a spectral symphony playing out in the shadows, a force capable of profound harm on both ecosystems and the delicate web of life. It dances in the heart of nuclear reactors, whispers in the dust kicked up by coal plants, and lingers for millennia in the wake of disaster. This is a story of innovation, ignorance, and resilience, a battle against a foe we cannot see, a song demanding our understanding and action.
A Legacy of Progress, a Burden of Ignorance:
Our understanding of radiation is a double-edged sword. Through its application in medicine, power generation, and countless scientific advancements, we have reaped the benefits of harnessing this potent energy. Yet, alongside progress, we have sown the seeds of our own contamination. Nuclear accidents like Chernobyl and Fukushima serve as stark reminders of the destructive potential unleashed when nuclear controls slip. But the threat extends far beyond such dramatic events.
Many Faces of a Spectral Foe:
Radiation pollution takes on numerous guises, each with its own insidious charm. Nuclear waste lingers for millennia, its radioactive isotopes poisoning the land and water, slowly sapping the lifeblood from ecosystems. Medical waste from discarded needles and equipment adds to the invisible burden, while industrial emissions from coal-fired power plants spew radioactive particulates into the air, painting the skies with a silent threat.
An Assault on the Invisible Threads of Life:
The impact of radiation pollution ripples through the biosphere, a hidden assassin disrupting the delicate dance of life. At the cellular level, ionizing radiation tears through DNA, wreaking havoc on the blueprints of life. Mutations arise, deformities blossom, and the very mechanisms of reproduction are corrupted. Animals suffer birth defects, cancers bloom in the shadows, and entire populations teeter on the brink of collapse.
Beyond the Immediate Harm: A Shadow's Legacy:
The consequences of radiation pollution extend far beyond the initial blast or spill. Environmental contamination persists for generations, poisoning food chains and jeopardizing future generations. Mutations can linger in a population's genetic pool, casting a long and unforeseen shadow on the tapestry of life. The psychological burden of living under a radioactive cloud adds another layer of complexity, eroding trust, disrupting communities, and leaving an indelible mark on the human spirit.
Facing the Spectral Threat: A Collective Challenge
Confronting radiation pollution demands a unified response, a tapestry woven from the threads of international cooperation, scientific innovation, and unwavering commitment.
Radioactive waste
Radioactive pollution occurs when radioactive materials are released into the environment unintentionally. It can come from natural sources like radon gas or cosmic rays, or from human activities involving nuclear materials. Radioactive pollution contaminates surfaces, air, water, and bodies. Exposure to ionizing radiation emitted by radioactive materials can damage DNA and increase cancer risks, especially for skin, bone marrow, and thyroid cells that divide rapidly. Past nuclear accidents in India have caused radioactive pollution. Proper disposal of nuclear waste and minimizing nuclear activities can help prevent further radioactive pollution.
Nuclear hazards and human health
Radiations are the waves of energy that travels and spread all around in our environment. These radiations are useful as well harmful for us. Examples include visible light, radio waves, microwaves, infrared and ultraviolet lights, X-rays, and gamma-rays, etc.
The differences between these various types of radiation consist in some physical properties such as energy, frequency, and wavelength.
Radiation pollution refers to the increase in the natural radiation levels in our surroundings due to human activities. It is said that in today’s world about 20% of radiation we are exposed to is due to human activities. The human activities that may release radiation involve activities with radioactive materials such as
1. mining,
2. handling and processing of radioactive materials,
3. handling and storage of radioactive waste,
4. use of radioactive reactions to generate energy (nuclear power plants),
5. use of radiation in medicine (e.g. X-Rays) and research.
Radiation pollution
Radiation pollution is caused by radioactive substances released into the environment through human activities like nuclear power plants, nuclear weapons, uranium mining, and medical procedures. There are two types of radiation - ionizing radiation which can damage DNA and cause cancer, and non-ionizing radiation which is generally less dangerous. Exposure to radiation can cause health effects ranging from skin irritation to death depending on the dose received and parts of the body exposed. Proper disposal of nuclear waste and safety measures around nuclear materials and accidents can help prevent radiation pollution.
July 18 july_24_possible_health_effects_of_nu
Ionizing radiation from nuclear plants and explosions can damage human health by breaking chemical bonds and causing cancer. The effects depend on exposure time, with initial symptoms being nausea and fatigue and higher exposures potentially causing organ damage, loss of consciousness, and death. Two types of radiation produced by nuclear reactions - cesium-137 and iodine-131 - are especially dangerous as they can accumulate in food and water and irradiate the body from inside over long periods of time due to their long half-lives. Exposure levels over 500,000 microsieverts can make people sick within hours or weeks depending on dose.

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.

It can come from natural sources like radon gas or cosmic rays, or from human activities involving nuclear materials. Radioactive pollution contaminates surfaces, air, water, and bodies. Exposure to ionizing radiation emitted by radioactive materials can damage DNA and increase cancer risks, especially for skin, bone marrow, and thyroid cells that divide rapidly. Past nuclear accidents in India have caused radioactive pollution. Proper disposal of nuclear waste and minimizing nuclear activities can help prevent further radioactive pollution.
Nuclear hazards and human health
Radiations are the waves of energy that travels and spread all around in our environment. These radiations are useful as well harmful for us. Examples include visible light, radio waves, microwaves, infrared and ultraviolet lights, X-rays, and gamma-rays, etc.
The differences between these various types of radiation consist in some physical properties such as energy, frequency, and wavelength.
Radiation pollution refers to the increase in the natural radiation levels in our surroundings due to human activities. It is said that in today’s world about 20% of radiation we are exposed to is due to human activities. The human activities that may release radiation involve activities with radioactive materials such as
1. mining,
2. handling and processing of radioactive materials,
3. handling and storage of radioactive waste,
4. use of radioactive reactions to generate energy (nuclear power plants),
5. use of radiation in medicine (e.g. X-Rays) and research.
Radiation pollution
Radiation pollution is caused by radioactive substances released into the environment through human activities like nuclear power plants, nuclear weapons, uranium mining, and medical procedures. There are two types of radiation - ionizing radiation which can damage DNA and cause cancer, and non-ionizing radiation which is generally less dangerous. Exposure to radiation can cause health effects ranging from skin irritation to death depending on the dose received and parts of the body exposed. Proper disposal of nuclear waste and safety measures around nuclear materials and accidents can help prevent radiation pollution.

Ionizing radiation from nuclear plants and explosions can damage human health by breaking chemical bonds and causing cancer. The effects depend on exposure time, with initial symptoms being nausea and fatigue and higher exposures potentially causing organ damage, loss of consciousness, and death. Two types of radiation produced by nuclear reactions - cesium-137 and iodine-131 - are especially dangerous as they can accumulate in food and water and irradiate the body from inside over long periods of time due to their long half-lives. Exposure levels over 500,000 microsieverts can make people sick within hours or weeks depending on dose.

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.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...
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.
