On the Hautus test for exponentially stable $C_0$-groups (2009)
For finite-dimensional systems the Hautus test is a well-known and easy checkable condition for observability. Russell and Weiss [SIAM J. Control Optim, 32 (1994), pp. 1--32] suggested an...
Zero-class admissibility of observation operators (2008)
Jacob, B., Partington, J. R., Pott, S.
An admissible observation operator is zero-class admissible if the norm of the output map tends to zero as the time tends to zero. Sufficient and necessary conditions for zero-class admissibility of...
In this paper we consider time--varying linear systems on Hilbert spaces and study the optimal control problem with indefinite performance criteria over a finite horizon interval. Due to the...

On Approximate Observability of Strongly Stable Systems (2006)
The Hautus test of Russelll and Weiss is sufficient for approximately observability when the system is exponentially stable. By means of an example we show that this does not hold when the system is...
Prolonged daily exposure to IV cocaine results in tolerance to its stimulant effects (2005)
Ben-Shahar, O, Moscarello, J M, Jacob, B, Roarty, M P, Ettenberg, A
We have previously shown that 1 h, but not 6 h, of daily access to IV cocaine induces a sensitized response to IV cocaine challenge after 14 days of withdrawal. Here we tried to replicate these...
Scaling properties in the production range of shear dominated flows (2005)
Casciola, C. M., Gualtieri, P., Jacob, B., Piva, R.
Recent developments in turbulence are focused on the effect of large scale anisotropy on the small scale statistics of velocity increments. According to Kolmogorov, isotropy is recovered in the large...
The Weiss conjecture on admissibility of observation operators for contraction semigroups (2001)
We prove the conjecture of George Weiss for contraction semigroups on Hilbert spaces, giving a characterization of infinite-time admissible observation functionals for a contraction semigroup, namely...

Double scaling and intermittency in shear dominated flows (2001)
Casciola, C. M., Benzi, R., Gualtieri, P., Jacob, B., Piva, R.
The Refined Kolmogorov Similarity Hypothesis is a valuable tool for the description of intermittency in isotropic conditions. For flows in presence of a substantial mean shear, the nature of...
Experimental assessment of a new form of scaling law for near-wall turbulence (2001)
Jacob, B., Olivieri, A., Casciola, C. M.
Scaling laws and intermittency in the wall region of a turbulent flow are addressed by analyzing moderate Reynolds number data obtained by single component hot wire anemometry in the boundary layer...
Disproof of an admissibility conjecture of Weiss (2000)
Two conjectures on admissible control operators by George Weiss are disproved in this paper. One conjecture says that an operator $B$ defined on an infinite-dimensional Hilbert space $U$ is an...
Disproof of two conjectures of George Weiss (2000)
Two conjectures that were posed by Weiss almost ten years ago are shown not to hold. The first conjecture states that a scalar operator is admissible if and only a certain resolvent estimate holds....
