Humanoid Occupancy: Enabling A Generalized Multimodal Occupancy Perception System on Humanoid Robots
Humanoid robot technology is advancing rapidly, with manufacturers introducing diverse heterogeneous visual perception modules tailored to specific scenarios. Among various perception paradigms, occupancy-based representation has become widely recognized as particularly suitable for humanoid robots, as it provides both rich semantic and 3D geometric information essential for comprehensive environmental understanding. In this work, we present Humanoid Occupancy, a generalized multimodal occupanc…

Color and Transparency from Quantum Geometry
The optical properties of solids are governed not only by their energy band dispersions but also by the quantum geometry of Bloch states. While the role of energy bands in determining the perceived optical appearance of materials, such as color and transparency, is well established, the influence of quantum geometry remains elusive. Here, we demonstrate that the color and transparency of materials can be direct manifestations of their underlying quantum geometry. To illustrate this principle, w…

Trumpmafia step 2: Les Etats-Unis vont taxer des exportations.
Officiellement, l’opération est présentée comme un «partage de revenus» en échange de l’obtention de licences pour l’exportation.
La logique est infaillible: les entreprises qui exportent seraient en effet des traîtres qui volent aux américains les produits qu’ils ont manufacturés pour simple appât de gain. https://www.letemps.ch/economie/finance/apres-les-tarifs-douaniers-donald-trump-songe-maintenant-a-taxer-les-exportations-americaines

Strategic Adoption of 3D Printing in Multi-Product Supply Chains: Cost and Capacity Considerations
This paper explores the integration of Additive Manufacturing (or 3D printing) into decentralized supply chains, focusing on the strategic decisions manufacturers and retailers make when facing capacity constraints. Using a Stackelberg game framework, we analyze how AM impacts traditional wholesale pricing across two scenarios. First, a manufacturer producing two distinct products and second, a case involving multiple products, each affected by AM's capacity limitations. For the first scenario,…

Below 100 ps CTR using FastIC+, an ASIC including on-chip digitization for ToF-PET and beyond
This work presents the 8-channel FastIC+, a low-power consumption and highly configurable multi-channel front-end ASIC with internal digitization, for the readout of photo-sensors with picosecond time resolution and intrinsic gain. This ASIC, manufactured in 65 nm CMOS technology, can readout positive or negative polarity sensors and provides a digitized measurement of the arrival time and energy of the detected events with a power consumption of 12.5 mW per channel. On-chip digitization is exe…
