Aharonov-Bohm Effect and Hidden Photons

Signs of hypothetical light gauge bosons from a hidden sector may appear in Aharonov-Bohm-like experiments. The absence of signal in carried on experiments allow us to set a modest constraint to the mass and coupling constant of these particles. Our findings open the possibility to exploit the leaking of hidden magnetic field in a different setup of experiments.Comment: Contributed to the 9th Patras Workshop on Axions, WIMPs and WISPs, Mainz, June 24-28, 201

Improved retort for cleaning metal powders with hydrogen

Improved cleaning retort produces uniform temperature distribution in the heated zone and minimizes hydrogen channeling through the powder bed. Retort can be used for nonmetallic powders, sintering in a reducing atmosphere, and for cleaning powders in reduction atmospheres other than hydrogen

Domination in the Anthropocene

The critique of human domination is a tenet of environmental thinking. Now, the rise of the Anthropocene has increased the risk that survivalism obscures nonhuman emancipation as a public and private goal: if the conversation about the Anthropocene keeps focusing on the dangerous disruption of planetary systems, fear of extinction can relegate nonhuman emancipation indefinitely. Furthermore, the language of the Anthropocene privileges terms such as «transformation» or «hybridization», overshadowing how nature has been, and continues to be, colonized by human beings. Unsurprisingly, the name of the new epoch puts humanity at the center of Earth's history, turning the «anthropos» into the main character of the planetary drama. It would thus seem that the Anthropocene's irruption hinders the critique and removal of domination. However, as this paper will argue, that is not necessarily the case. The Anthropocene can provide a more realistic account of socionatural relations and thus put past and present domination into a wider context. In turn, this opens up new possibilities for the critique of domination -possibilities that do not rely on traditional arguments regarding capitalism's rapaciousness or human's lack of empathy. While the complete absence of domination will remain an ideal goal for the time being, an enlightened or managed domination can meaningfully reduce the harm done to nature in a non-ideal world and prepare us for a future where humanity self-consciously overcomes the acquired habit of domination

Detecting a Vector Based on Linear Measurements

We consider a situation where the state of a system is represented by a real-valued vector. Under normal circumstances, the vector is zero, while an event manifests as non-zero entries in this vector, possibly few. Our interest is in the design of algorithms that can reliably detect events (i.e., test whether the vector is zero or not) with the least amount of information. We place ourselves in a situation, now common in the signal processing literature, where information about the vector comes in the form of noisy linear measurements. We derive information bounds in an active learning setup and exhibit some simple near-optimal algorithms. In particular, our results show that the task of detection within this setting is at once much easier, simpler and different than the tasks of estimation and support recovery
