Superconductivity in the repulsive Hubbard model: an asymptotically exact weak-coupling solution

, 2010
We study the phase diagram of the Hubbard model in the limit where U, the onsite repulsive interaction, is much smaller than the bandwidth. We present an asymptotically exact expression for T$_c$, the superconducting transition temperature, in terms of ...

Detection and emotional evaluation of an electric vehicle’s exterior sound in a simulated environment [PDF]

, 2013
Electric vehicles are quiet at low speeds and thus potentially pose a threat to pedestrians’ safety. Laws are formulating worldwide that mandate these vehicles emit sounds to alert the pedestrians of the vehicles’ approach.

Heavy Prussian Blue Analog with Magnetic Ordering above 400 K

Advanced Science, Volume 13, Issue 5, 27 January 2026.
A cyanido‐bridged vanadium(II)–hexacyanomolybdate(III) Prussian Blue analog synthesized mechanochemically exhibits ferrimagnetic ordering above 400 K. SQUID magnetometry and XMCD experiments confirm antiparallel alignment of V and Mo moments. This establishes hexacyanomolybdate(III) as a robust precursor for high‐temperature molecule‐based magnets ...

NVH-Systemsimulation eines Traktors mit hydrostatisch-mechanischem Leistungsverzweigungsgetriebe

Landtechnik, 2020
Das Noise-Vibration-Harshness(NVH)-Verhalten von Fahrzeugen ist heutzutage ein wichtiges Kaufkriterium. Zur Analyse des NVH-Verhaltens in frühen Phasen des Produktentwicklungsprozesses werden validierte Modellierungsmethoden benötigt.

Controlling Rotational Motion of Nonplanar Porphyrin Atropisomers by Metal Coordination

Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.
The unpredictable rotational barriers of nonplanar porphyrin atropisomers can be combated using metal coordination to form porphyrin superstructures, selectively capturing a single atropisomer from an unstable mixture. ABSTRACT Porphyrin atropisomerism is an outstanding tool for the accessibility of shape‐specific molecules, yet over 20 years after the

Perception enhancement for steer-by-wire systems [PDF]

, 2005
Modern automobiles are safer and more comfortable than ever before. If there is one criticism that can be made, however, it is that the achievement of higher levels of comfort has sometimes come at the expense of a lack of driver involvement. The issue
