Laser spectroscopy is used in many applications such as atmospheric physics, pollution monitoring, and analyzing solid materials. Lasers allow for selective surface hardening with little part distortion and an inert coating eliminates fumes. One crucial factor for heat treatment is controlling laser beam irradiance on the part surface, typically between 500-5000 W/cm2. Ultra-short laser pulses as brief as picoseconds can be used to initiate and analyze chemical reactions such as protein folding. Powerful laser arrangements are used to produce extremely intense ultra-short pulses to attempt inducing fusion reactions in fuel pellets. Lasers are also used in applications such as confocal microscopy, laser capture microdissection, and directed-energy weapons.

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).

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
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.

4. Laser spectroscopy is used in many
different forms and in a wide range
of applications. For example,
atmospheric physics and pollution
monitoring profits from trace gas
sensing with differential absorption
LIDAR technology. Solid materials
can be analyzed with laser-induced
breakdown spectroscopy.
5. Heat treating with lasers allows selective surface hardening against wear with
little or no distortion of the component. Because this eliminates much part
reworking that is currently done, the laser system's capital cost is recovered in a
short time. An inert, absorbent coating for laser heat treatment has also been
developed that eliminates the fumes generated by conventional paint coatings
during the heat-treating process with CO2 laser beams.
One consideration crucial to the success of a heat treatment operation is control
of the laser beam irradiance on the part surface. The optimal irradiance
distribution is driven by the thermodynamics of the laser-material interaction and
by the part geometry.
Typically, irradiances between 500-5000 W/cm2 satisfy the thermodynamic
constraints and allow the rapid surface heating and minimal total heat input
required. For general heat treatment, a uniform square or rectangular beam is
one of the best options.
6.
7. Some laser systems, through the process of mode locking,
can produce extremely brief pulses of light - as short as
picoseconds or femtoseconds (10−12 - 10−15 seconds).
Such pulses can be used to initiate and analyze chemical
reactions, a technique known as photochemistry.
The short pulses can be used to probe the process of the
reaction at a very high temporal resolution, allowing the
detection of short-lived intermediate molecules.
This method is particularly useful in biochemistry, where it
is used to analyse details of protein folding and function.
8. Laser barcode
scanners are ideal for
applications that
require high speed
reading of linear codes
or stacked symbols.
9. This involves atom trapping, a method
where a number of atoms are confined
in a specially shaped arrangement
of electric and magnetic fields. Shining
particular wavelengths of light at the
ions or atoms slows them down,
thus cooling them. As this process is
continued, they all are slowed and have
the same energy level, forming an
unusual arrangement of matter known
as a Bose–Einstein condensate.
10. Some of the world's most powerful and complex
arrangements of multiple lasers and optical
amplifiers are used to produce extremely high
intensity pulses of light of extremely short duration,
e.g. laboratory for laser energetics, National Ignition
Facility, GEKKO XII, Nike laser, Laser
Mégajoule, HiPER. These pulses are arranged such
that they impact pellets of tritium–
deuterium simultaneously from all directions, hoping
that the squeezing effect of the impacts will induce
atomic fusion in the pellets. This technique, known
as "inertial confinement fusion", so far has not been
able to achieve "breakeven", that is, so far the fusion
reaction generates less power than is used to power
the lasers, but research continues.
11. Confocal laser scanning
microscopy and Two-photon excitation
microscopy make use of lasers to obtain
blur-free images of thick specimens at
various depths. Laser capture
microdissection use lasers to procure
specific cell populations from a tissue
section under microscopic visualization.
Additional laser microscopy techniques
include harmonic microscopy, four-wave
mixing microscopy and interferometric
microscopy
12.
13. A directed-energy weapon (DEW) emits highly
focused energy, transferring that energy to a target
to damage it.
Potential applications of this technology include anti-
personnel weapon systems, potential missile
defense system, and the disabling of lightly armored
vehicles such as cars, drones, watercraft, and
electronic devices such as mobile phones.
An electrolaser lets ionization occur, and then sends
a powerful electric current down the
conducting ionized track of plasma so formed,
somewhat like lightning.
14. Laser guidance is a technique
of guiding a missile or other projectile
or vehicle to a target by means of a
laser beam.
15. This is a low-power laser pointer used to indicate a
target for a precision-guided munition, typically
launched from an aircraft. The guided munition
adjusts its flight-path to home in to the laser light
reflected by the target, enabling a great precision
in aiming. The beam of the laser target designator
is set to a pulse rate that matches that set on the
guided munition to ensure munitions strike their
designated targets and do not follow other laser
beams which may be in use in the area. The laser
designator can be shone onto the target by an
aircraft or nearby infantry. Lasers used for this
purpose are usually infrared lasers, so the enemy
cannot easily detect the guiding laser light.
