Superior outcomes of decompression with an interlaminar dynamic device versus decompression alone in patients with lumbar spinal stenosis and back pain: a cross registry study

Surgical decompression for lumbar spinal stenosis (LSS) has been associated with poorer outcomes in patients with pronounced low back pain (LBP) as compared to patients with predominant leg pain. This cross re...

AutoMedic: Fuzzy Control Development Platform for a Mobile Heart-Lung Machine

Cardiogenic shock due to myocardial infarction is still associated with a high mortality of more than 60%. Early treatment of patients having a low cardiac output with an extra-corporal circulatory support sys...

Increased IκB kinase activity is associated with activated NF-κB in acute myeloid blasts

NF-κB/Rel transcription factors are modulators of immune and inflammatory processes and are also involved in malignancy. Phosphorylation of the IκB inhibitors by the IκB kinase (IKK) complex leads to their pro...

Postulates for time evolution in quantum mechanics

A detailed list of postulates is formulated in an algebraic setting. These postulates are sufficient to entail the standard time evolution governed by the Schrödinger or Dirac equation. They are also necessary.....

Mouse genes encoding DNA topoisomerase I

We have initiated a genetic analysis of the physiologically important enzyme type I DNA topoisomerase in mouse. The exon-intron structures of the 5′ part and the 3′ part of the active gene, Top-1, were determined...

Perturbations of Supersymmetric Systems in Quantum Mechanics

The methods of supersymmetry are extended to the factorization method. The degeneracy of levels in factorizable systems is broken under perturbations. With the methods of supersymmetry it is possible to state ...

Longitudinal contunuity of the subrhabdomeric cisternae in the photoreceptors of the compound eye of the drone, Apis mellifera

It is shown that the subrhabdomeric cisternae of the honey bee drone photoreceptor cell constitute a single structure with a continuous lumen, that extends over at least 15 μm and perhaps the whole length of t...

On the degree of ionization in the TFW theory

We give a simplified proof of the theorem which says that in Thomas-Fermi-Von Weizsaecker theory the surplus charge of bounded electrons cannot exceed the combined charge of the nuclei in absolute value.

Nonlinear von neumann equations for quantum dissipative systems

For pure states nonlinear Schrödinger equations, the so-called Schrödinger-Langevin equations are well-known to model quantum dissipative systems of the Langevin type. For mixtures it is shown that these wave ...
