[HTML][HTML] Regulated fluctuations in nanog expression mediate cell fate decisions in embryonic stem cells
T Kalmar, C Lim, P Hayward, S Munoz-Descalzo… - PLoS …, 2009 - journals.plos.org
There is evidence that pluripotency of mouse embryonic stem (ES) cells is associated with
the activity of a network of transcription factors with Sox2, Oct4, and Nanog at the core. Using
fluorescent reporters for the expression of Nanog, we observed that a population of ES cells …

Near-optimal dynamic trajectory generation and control of an omnidirectional vehicle
T Kalmár-Nagy, R D'Andrea, P Ganguly - Robotics and Autonomous …, 2004 - Elsevier
This paper describes a computationally inexpensive, yet high performance trajectory
generation algorithm for omnidirectional vehicles. It is shown that the associated non-linear
control problem can be made tractable by restricting the set of admissible control functions …

Wnt/Notch signalling and information processing during development
P Hayward, T Kalmar, AM Arias - Development, 2008 - dev.biologists.org
The Wnt and Notch signalling pathways represent two major channels of communication
used by animal cells to control their identities and behaviour during development. A number
of reports indicate that their activities are closely intertwined during embryonic development …

Subcritical Hopf bifurcation in the delay equation model for machine tool vibrations
T Kalmár-Nagy, G Stépán, FC Moon - Nonlinear Dynamics, 2001 - Springer
We show the existence of a subcritical Hopf bifurcation in thedelay-differential equation
model of the so-called regenerative machine toolvibration. The calculation is based on the
reduction of the infinite-dimensional problem to a two-dimensional center manifold. Due to …

A simple and efficient method for PCR amplifiable DNA extraction from ancient bones
T Kalmár, CZ Bachrati, A Marcsik… - Nucleic Acids …, 2000 - academic.oup.com
A simple and effective modified ethanol precipitation-based protocol is described for the
preparation of DNA from ancient human bones. This method is fast and requires neither
hazardous chemicals nor special devices. After the powdering and incubating of the bone …

[BOOK][B] Delay differential equations
B Balachandran, T Kalmár-Nagy, DE Gilsinn - 2009 - Springer
Delay differential equations (DDEs) are important in many areas of engineering and
science. The aim of this book is to bring together contributions from leading experts on the
theory and applications of functional and DDEs. The editors have strived throughout to point …

Nonlinear models for complex dynamics in cutting materials
FC Moon, T Kalmar-Nagy - … of the Royal …, 2001 - rsta.royalsocietypublishing.org
This paper reviews the prediction of complex, unsteady and chaotic dynamics associated
with material–cutting processes through nonlinear dynamical models. The status of
bifurcation phenomena such as subcritical Hopf instabilities is assessed. A new model using …

The effect of atorvastatin therapy on lecithin: cholesterol acyltransferase, cholesteryl ester transfer protein and the antioxidant paraoxonase
A Kassai, L Illyés, HZ Mirdamadi, I Seres, T Kalmár… - Clinical …, 2007 - Elsevier
Objectives: The aim of our study was to examine the influence of atorvastatin on lipid
parameters, particularly on HDL, and on the activity of LCAT and CETP and how they affect
the activity of the HDL-associated antioxidant enzyme paraoxonase. Design and methods …

Comparison of maternal lineage and biogeographic analyses of ancient and modern Hungarian populations
G Tömöry, B Csányi, E Bogácsi‐Szabó… - American journal of …, 2007 - Wiley Online Library
The Hungarian language belongs to the Finno‐Ugric branch of the Uralic family, but
Hungarian speakers have been living in Central Europe for more than 1000 years,
surrounded by speakers of unrelated Indo‐European languages. In order to study the …
