Threshold-linear networks are a common class of firing rate models that describe recurrent interactions among neurons. Unlike their linear counterparts, these networks generically possess multiple stable fixed points (steady states), making them viable candidates for memory encoding and retrieval. In this work, we characterize stable fixed points of general threshold-linear networks with consta...

METHODS: The results of LNT for LEL were compared between the conventional single LNT group (control group; n = 21 limbs), the multiple LNFs group (n = 13), and the prefabricated lympho-venous shunt group (n = 13) in terms of volume improvement (the LEL index), lymphoscintigraphy findings, and the rate of functional survival and lymph node sizes (evaluated using ultrasonography) at 6 months aft...

The abatement of the pollutants deriving from diesel engines in vehicle sector still represents an interesting scientific and technological challenge due to increasingly limiting regulations. Meeting stringent limits NOx soot emissions requires a catalytic system with great complexity, size units, number as well increased fuel consumption. Thus, after-treatment device for use integrated catalys...

We present two linked theorems on passivity: the passive behavior theorem, parts 1 and 2. Part 1 provides necessary and sufficient conditions for a general linear system, described by a set of high order differential equations, to be passive. Part 2 extends the positive-real lemma to include uncontrollable and unobservable state-space models.

For the purpose of a global analysis of the effects of low radiation doses in mammals, the International Centre for Low Dose Radiation Research (ICLDRR) is collecting, in one database, all accessible information on cancer induction in animals following exposure to low doses and dose rates of ionizing radiation. A large number of these studies are identified and succinctly described in the Inter...
