Abstract: Nuclear security operations and forensic investigations require the utilization of a suite of instruments ranging from passive gamma spectrometers to high-precision laboratory sample analyzers. Gamma spectroscopy survey is further broken down into wide-area search performed with large-volume scintillator-based mobile survey spectrometers which are integrated with geographic position sensors for mapping and identification of hot zones, and high-precision long-dwell measurements using solid state spectrometers for follow-on characterization to establish isotopic content and ratios. While performing well at detecting the presence, quantity and type of radioactivity, all of these methods have limited ability to determine the location of a source of radioactivity. In recent years, technology advances have resulted in gamma imager devices which can create an image of the distribution of radioactive sources using the gamma emissions which accompany radioactive decay, and overlay this on an optical photograph of the environment. These gamma imaging devices have arisen out of methods developed for medical physics, experimental particle physics, and astrophysics, resulting in a proliferation of different technological approaches. Those responsible for establishing a nuclear security concept of operations, require guidance to choose the proper gamma imager for each of the application spaces in a tiered response. Here the results of an intercomparison of two gamma imagers based on two widely different technologies, semiconductor and scintillator detectors, are presented. The optimal utilization of these imaging technologies in a tiered response is discussed based on the results of the trial. Finally, an outlook on future directions for gamma imaging advances is provided.

»„Man muss sein Gehirn nicht benutzen" — Studie warnt vor kognitiven Folgen durch KI im Unterricht:
Während KI-Tools in den Klassenzimmern Einzug halten, schlagen Forscher:innen Alarm. Eine neue Studie kommt zu dem Ergebnis, dass die neue Technologie vor allem Beziehungen negativ beeinflussen könnte«
Wer hätte dies je gedacht… moment mal um was geht es, um was denn genau, was labert die KI denn uns vor?!??

„Man muss sein Gehirn nicht benutzen": Studie warnt vor kognitiven Folgen durch KI im Unterricht | t3n
Während KI-Tools in den Klassenzimmern Einzug halten, schlagen Forscher:innen Alarm. Eine neue Studie kommt zu dem Ergebnis, dass die neue Technologie vor allem Beziehungen negativ beeinflussen könnte. Das Center for Universal Education der US-amerikanischen Brookings Institution hat die KI-Nutzung von Kindern und Jugendlichen untersucht. Im Rahmen des einjährigen Projekts führten die Forscher:innen Interviews und Diskussionsrunden […]

Abstract: The precise manipulation and analysis of neutron spin states are foundational for a wide range of physics experiments, from fundamental symmetry tests to materials science. To enable systematic characterization of neutron polarimetry devices, we have constructed and extended a monochromatic neutron beamline at the Spallation Neutron Source, Oak Ridge National Laboratory. The beamline delivers monochromatic neutrons and provides a flexible platform for deploying and evaluating advanced neutron spin manipulation instruments. We describe the design and commissioning of the extended beamline and present a proof-of-concept neutron polarimetry study using three devices: a supermirror neutron polarizer, a Mezei spin flipper, and an in situ neutron 3He spin analyzer system. Performance metrics, optimization strategies, and systematic effects are discussed, demonstrating the beamline utility for neutron instrumentation testing. These results establish the extended monochromatic beamline as a useful resource for the development and validation of neutron polarimetry technologies.

Die GI liefert einen interessanten Beitrag:
> Die Nationale Sicherheitsstrategie (NSS 2025) der USA offenbart das Ziel, Europa durch technologische Monopole in strategische Abhängigkeit zu führen.
[...] legt einen konkreten Fünf-Punkte-Plan für einen strategischen Kurswechsel vor.
Neu und gut finde ich diesen passenden Begriff:

Insgesamt ist die EU Situation klar formuliert und mit Lösungsansätzen:

Series D, Episode 11 - Orbit
VILA: It certainly takes some getting used to.
AVON: What does?
VILA: Knowing we've finally cracked it. All I want now is to find a way of living forever.
AVON: Hmmm.

Brainwaves meet spatial computing: Cognixion Vision Pro #noninvasive

Mishti Broor - 23. Brainwaves Meet Spatial Computing: Cognixion + Vision Pro
The partnership between Cognixion and Apple Vision Pro represents something bigger than a clever product integration. It represents the maturation of non-invasive brain-computer interface technology reaching beyond laboratory settings into a mainstream platform with millions of potential users. In

For Saint Augustine of Hippo, writing in North Africa in the fourth century,
authentic attention placed us in relation with the divine.
For Saint Ignatius of Loyola, holed up in his cave in Catalonia in the 1520s,
what he called “attentive contemplation” was both a daily practice and a moral imperative.
During the Enlightenment, close attention emerged as a virtue essential to knowledge and disciplined investigation,
-- as demonstrated in 1740, when the natural…
