Fossils provide evidence of past life by preserving remains or traces of prehistoric organisms. There are several types of fossils that are formed through different processes like petrification, replacement, molds, casts, and carbonization. Fossils can be directly preserved or their presence indirectly inferred through tracks, burrows, coprolites, and gastroliths. Conditions like rapid burial and possession of hard parts favor fossil preservation. The principle of fossil succession established that fossils are found in a definite order in the geologic record. Index fossils and key beds are used to correlate rock layers and determine their relative ages. Radiometric dating techniques like carbon-14 dating are used to assign numerical ages to rocks and objects by measuring the
The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. Geologists have divided Earth's history into a series of time intervals. These time intervals are not equal in length like the hours in a day. Instead the time intervals are variable in length. This is because geologic time is divided using significant events in the history of the Earth.
T he geologic time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used bygeologists, paleontologists, and other earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. The table of geologic time spans presented here agrees with the dates and nomenclature set forth by theInternational Commission on Stratigraphy standard color codes of the International Commission on Stratigraphy.
Evidence from radiometric dating indicates that the Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place in each period. Different spans of time on the GTS are usually delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions.

The "best" age for the Earth is based on the time required for the lead isotopes in four very old lead ores (galena) to have evolved from the composition of lead at the time the Solar System formed, as recorded in the Canyon Diablo iron meteorite (Arizona, USA).
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Fossils
1. Fossils: evidence of past life
Remains or traces of prehistoric life
Types of fossils
• Petrified – cavities and pores are filled with
precipitated mineral matter
• Formed by replacement – cell material is
removed and replaced with mineral matter
• Mold – shell or other structure is buried and
then dissolved by underground water
• Cast – hollow space of a mold is filled with
mineral matter
2. Fossils: evidence of past life
Types of fossils
• Carbonization – organic matter becomes a thin
residue of carbon (liquid and gas gets squeezed
out due to pressure)
• Impression – replica of the fossil’s surface
preserved in fine-grained sediment
• Preservation in amber – hardened resin of
ancient trees surrounds an organism
4. Fossils: evidence of past life
Types of fossils
• Indirect evidence includes
• Tracks – footprints get preserved in
• Burrows
• Coprolites – fossil dung and stomach contents
• Gastroliths – stomach stones used to grind food by
some extinct reptiles
5. Fossils: evidence of past life
Conditions favoring preservation
• Rapid burial
• Possession of hard parts
Fossils and correlation
• Principle of fossil succession
• Fossils succeed one another in a definite and
determinable order
• Proposed by William Smith – late 1700s and early
1800s
7. Fossils: evidence of past life
Fossils and correlation
• Index fossils
• Widespread geographically
• Existed for a short range of geologic time
• Key Bed Layers
• A thin sediment layer deposited instantaneously
that is very widespread geographically and contains
distinctive or easily recognizable material
• Ex: Asteroid impact iridium 65 myo rock
8. Radioactivity and
radiometric dating
Atomic structure reviewed
• Nucleus
• Protons – positively charged
• Neutrons

neutrons in an atom’s nucleus
• Isotope
• Variant of the same parent atom
• Different number of neutrons and mass number
10. Radioactivity and
radiometric dating
Radioactivity
• Spontaneous breaking apart (decay) of atomic
nuclei
• Radioactive decay

• Daughter products – isotopes formed from the
decay of a parent
13. Radioactivity and
radiometric dating
Radiometric dating
• Half-life – the time for one-half of the
radioactive nuclei to decay
• Requires a closed system
• Cross-checks are used for accuracy
• Complex procedure
• Yields numerical dates
16. Radioactivity and
radiometric dating
Carbon-14 dating
• Half-life of only 5,730 years
• Used to date very recent events
• Carbon-14 produced in upper atmosphere
• Incorporated into carbon dioxide
• Absorbed by living matter
• Useful tool for anthropologists, archaeologists,
historians, and geologists who study very
recent Earth history
