Once the protective structure was in place the work to deactivate the bomb could begin. An initial plan to cut into the bomb and render it safe to transport had to be abandoned, after water used in the cutting process threatened the stability of the sand walls.

Bildbeschreibung (Deutsch)
Das Bild zeigt ein aus Metall gefertigtes Miniatur-Fahrrad, dessen Räder durch massive Sechskant-muttern ersetzt sind. Die Konstruktion ist formal stabil, mechanisch jedoch funktionsunfähig: Die überdimensionierte Ordnung der Bauteile verhindert jede Rotation. Bewegung - als Voraussetzung für Transport, Anpassung und Lebendigkeit - ist ausgeschlossen.
Im Kontext des Stabilismus, des Mallinckrodt-Zyklus und der Ontologie der Schwingung wird das Objekt zur Metapher für Systeme, die durch Überregulierung ihre eigene Funktion verlieren.
Stabilität ohne Schwingungsfreiheit kippt in Starrheit; Ordnung jenseits der Toleranzgrenzen zerstört genau das, was sie erhalten sollte. Das Bild illustriert damit den systemischen Punkt, an dem Sicherheit in Dysfunktion umschlägt.🖖

Image Description (English)
The image depicts a miniature bicycle constructed from metal, with its wheels replaced by solid hex nuts. While the structure appears mechanically robust, it is functionally inert: excessive structural rigidity prevents rotation. Motion - the fundamental prerequisite for transport, adaptation, and life - is rendered impossible.
Within the framework of Stabilism, the Mallinckrodt Cycle, and the Ontology of Oscillation, the object becomes a metaphor for systems that collapse under excessive order. Stability without oscillatory freedom turns into rigidity; regulation beyond tolerance thresholds eliminates functionality. The image thus visualizes the critical transition point where order no longer sustains a system but actively disables it.🖖

entropy-regularized optimal transport with spectral and integral-geometric techniques. As some of the arguments do not rely on the Riemannian structure, our work also paves the way towards understanding stability of optimal transport in more general [3/4 of https://arxiv.org/abs/2504.05412v1]

Gemini help I'm a beaver in beaver school and I need to pass the test tomorrow how to build the best dam URGENT

Building the
best dam requires combining natural instincts with engineering savvy! To ace your test, remember these core principles that ensure strength, efficiency, and environmental harmony:
Key Principles for Dam Building Success
1. Material Science is Everything
Beavers are masters of resource management. The best dams use a combination of materials, strategically placed [1]:

Structure & Strength: Use thick, sturdy logs and branches as the main skeleton [1, 2]. Position the thickest end facing upstream to take the initial force of the water [2].
Sealing & Waterproofing: This is the most critical part! Use mud, rocks, grass, leaves, and smaller twigs to fill the gaps. Pack the material tightly to create a watertight barrier [1, 2].
Strategic Sourcing: Always cut fresh, green wood (like willow, aspen, or alder). They are easier to transport, hold together better, and some pieces might even sprout, adding to the dam's long-term stability [2].

2. Location, Location, Location
A strong structure in a bad spot is a failing grade. Choose your site wisely [2]:

Narrow is Better: Look for a narrow section of the stream with slow-moving water [2]. This requires less material to span the gap and reduces water pressure on the structure [2].
