On supersymmetries in nonrelativistic quantum mechanics (2005)

Beckers, J., Debergh, N., Nikitin, A. G.

One-dimensional nonrelativistic systems are studied when time-independent potential interactions are involved. Their supersymmetries are determined and their closed subsets generating kinematical...

Reconstructions of Mediterranean ocean temperature fields back to 1950 show a proxy relationship between heat content changes in the North Atlantic and the Western Mediterranean Deep Water ( WMDW)...

Molecular Phenotyping of Mouse Mutant Resources by RNA Expression Profiling (2002)

Beckers,J., Hoheisel,J., Mewes,W., Vingron,M.

Non-Hermitian oscillator-like Hamiltonians and $\lambda$-coherent states revisited (2001)

Beckers, J., Cariñena, J. F., Debergh, N., Marmo, G.

Previous $\lambda$-deformed {\it non-Hermitian} Hamiltonians with respect to the usual scalar product of Hilbert spaces dealing with harmonic oscillator-like developments are (re)considered with...

On oscillatorlike Hamiltonians and squeezing (2000)

Beckers, J., Debergh, N., Szafraniec, F. H.

Generalizing a recent proposal leading to one-parameter families of Hamiltonians and to new sets of squeezed states, we construct larger classes of physically admissible Hamiltonians permitting new...

On oscillatorlike developments and further improvements in squeezing (1999)

Beckers, J., Debergh, N., Szafraniec, F. H.

A recent proposal of new sets of squeezed states is seen as a particular case of a general context admitting realistic physical Hamiltonians. Such improvements reveal themselves helpful in the study...

Hox gene expression in limbs: colinearity by opposite regulatory controls (1999)

Herault, Y., Beckers, J., Gerard, M., Duboule, D.

Genes of the HoxD complex have a crucial role in the morphogenesis of vertebrate limbs. During development, their functional domains are colinear with their genomic positions within the HoxD cluster...

On realizations of nonlinear Lie algebras by differential operators (1998)

Beckers, J., Brihaye, Y., Debergh, N.

We study realizations of polynomial deformations of the sl(2,R)- Lie algebra in terms of differential operators strongly related to bosonic operators. We also distinguish their finite- and...

Genetic analysis of a conserved sequence in the HoxD complex: regulatory redundancy or limitations of the transgenic approach? (1998)

Beckers, J., Duboule, D.

Extensive sequencing in the HoxD complex of several vertebrate species has revealed a set of conserved DNA sequences interspersed between neighboring Hox genes. Their high degree of conservation...

Genetic analysis of a Hoxd-12 regulatory element reveals global versus local modes of controls in the HoxD complex (1998)

Herault, Y., Beckers, J., Kondo, T., Fraudeau, N., Duboule, D.

Vertebrate Hoxd genes are essential determinants of limb morphogenesis. In order to understand the genetic control of their complex expression patterns, we have used a combined approach involving...

Parasupersymmetric Quantum Mechanics with Generalized Deformed Parafermions (1996)

Beckers, J., Debergh, N., Quesne, C.

A superposition of bosons and generalized deformed parafermions corresponding to an arbitrary paraquantization order $p$ is considered to provide deformations of parasupersymmetric quantum mechanics....

On Nonlinear Angular Momentum Theories, Their Representations and Associated Hopf Structures (1996)

Abdesselam, B., Beckers, J., Chakrabarti, A., Debergh, N.

Nonlinear $sl(2)$ algebras subtending generalized angular momentum theories are studied in terms of undeformed generators and bases. We construct their unitary irreducible representations in such a...

Transgenic analysis of a potential Hoxd-11 limb regulatory element present in tetrapods and fish (1996)

Beckers, J., Gerard, M., Duboule, D.

Genes of the HoxD complex related to the Drosophila Abd-B gene are involved in the morphogenesis of vertebrate paired appendages. Hoxd-11, for instance, is necessary in combination with other Hox...

On a Deformation of $sl(2)$ with Paragrassmannian Variables (1995)

Abdesselam, B., Beckers, J., Chakrabarti, A., Debergh, N.

We propose a new structure ${\cal U}^{r}_{\displaystyle{q}}(sl(2)) $. This is realized by multiplying $\delta$ ($q=e^{\delta}$, $\delta\in \CC$) by $\theta$, where $\theta$ is a real nilpotent...
