title: Phylogenetic trees of genus Oncidium Sw. based on analysis of DNA sequences

description: Genus Oncidium Sw. is widely regarded as a polyphiletic, and the taxonomic boundaries between him and such genera as Odontoglossum Kunth. or Miltonia Lindley remain blurred. The goal of the study was to determine the phylogenetic relationships within the genus Oncidium s.lato based on the DNA sequences analysis. The correlation between molecular data and geographical distribution of the studied species was also examined. Two markers were used for the analysis: the ITS sequence derived from the nuclear genome and the matK gene that is part of mitochondrial DNA. Sequences were obtained by DNA isolation from frozen leaves, polymerase chain reaction (PCR) and sequencing. For their analysis in the PAUP* program, a feature-based parsimony (MP) method was used, and for assessing the reliability of the resulting trees, the non-parametric bootstrap method. The ITS MP search resulted in 10 000 trees (CI=0.49; RI=0.631). The aligned matrix resulted in 814 characters of which 433 were parsimony informative. The matK MP search resulted in 10 000 trees (CI=0.505; RI=0.714). The aligned matrix resulted in 1359 characters of which 358 were parsimony informative. 
This dataset contains two image files with phylogenetic trees - the first one based on ITS analysis of 190 species and the second one based on the matK analysis of 154 species. The upper numbers above branches are the Fitch values and lower numbers are the bootstrap values. The information about geographical distribution is added.  The dataset includes also two NEXUS files (for ITS and for matK) with DNA sequences.

title: Simulation of a linear pneumatic actuator with 32 mm piston diameter, 14 mm piston rod diameter and 25 mm stroke

description: The aim of the simulation was to determine the dynamics of linear pneumatic actuators with different sizes and flow properties. The simulation used the actuator dynamics model as described in [1] and the St Venant - Wantzel's mass flow rate model. The simulation experiment was to calculate the pressure changes in both chambers of the actuator as well as the position and velocity of the piston during the stroke. The simulation results were saved in the default GNU Octave (text) format. The original purpose of the experiments was to obtain data to create a neural model of a pneumatic actuator.[1] Kiczkowiak T.: Algorithms and Models Applied in the Design of Pneumatic Driving Systems (in Polish), Koszalin 2005, Publishing House of Koszalin University of Technology

title: Adiabatic potential energy curves of the triplet Sigma ungerade plus states of the Lithium dimer

description: Adiabatic potential energy curves of the triplet Sigma ungerade plus states have been calculated for the Lithium dimer. The results of the five excited states of the symmetry triplet Sigma ungerade plus have been obtained by the nonrelativistic multireference configuration interaction (MRCI) method used with pseudopotentials describing the interaction of valence electrons with atomic cores. In this approach, only the valence electrons of the Li atom were treated explicitly. The core polarization potential has been also applied in calculations. All computations were performed by means of the MOLPRO program package. Presented potentials are ready to compare with the results of other theoretical results and potential energy curves derived from experiments.
The dataset is arranged in six columns. The first column contains distances in Bohr radius units [a0] between Lithium atoms. The consecutive five columns contain potential energies of interaction between Li atoms calculated for corresponding distances. Energies are shown in inverse centimeters units [cm-1]. All curves are tabulated according to internuclear distance from 3.2 [a0] to 88 [a0].

title: Minimal number of periodic points with the periods less or equal to r in the smooth homotopy class of simply-connected manifolds of dimension 5 and homology groups with the sum of ranks less or equal to10

description: An important problem in periodic point theory is minimization of the number of periodic points with periods &lt;= r in a given class of self-maps of a space. A closed smooth and simply-connected manifolds of dimension 5 and its self-maps f  with periodic sequence of Lefschetz numbers are considered. The topological invariant Jr[f] is equal to the minimal number of periodic points with the periods less or equal to r in the smooth homotopy class of f. For sufficiently large r the invariant Jr[f] is independent of the choice of r and in that case it is natural to write J[f] instead of Jr[f]. We provide the values of the simplified version of the invariant: J[f] (mod 2) (which is equal either J[f] or J[f]+1) for  manifolds of dimension 5 having the sum of ranks of homology groups less or equal 10. The results are based on the combinatorial scheme for computing J[f] introduced in “Minimization of the number of periodic points for smooth self-maps of simply-connected manifolds with periodic sequence of Lefschetz numbers” by G. Graff and A. Kaczkowska, [Cent. Eur. J. Math., 10(6), 2012, 2160-2172, https://doi.org/10.2478/s11533-012-0122-7]. The data contains text files of the form J[vector_of_ranks _of_homology_groups].txt. Each file consists of all possible triples, structured as follows: the first position contains a sequence of lists, where the i-th list corresponds to the degrees of non-zero eigenvalues of the i-th induced homomorphism, the second position contains a set of non-zero periodic expansion coefficients, the third position contains corresponding value of the invariant J[f].

title: Estimates for minimal number of periodic points for smooth self-maps of simply-connected manifolds

description: We consider a closed smooth connected and simply-connected manifold of dimension at least 4 and its self-map f. The topological invariant Dr[f] is equal to the minimal number of r-periodic points in the smooth homotopy class of f. We assume that r is odd and all coefficients b(k) of so-called periodic expansion of Lefschetz numbers of iterations are non-zero for all k dividing r and different from 1. We consider the simplified version of the invariant: Dr[f](mod 1) (which is equal either Dr[f] or Dr[f]+1).
The determination of the exact value of the invariant is a challenging task even for relatively small values of r and low-dimensional manifolds. Nevertheless, in this dataset we are able to provide the estimates for Dr[f](mod 1) for manifolds of dimension between 4 and 21. 
We consider an odd r that is a product of 10 prime numbers, each to the power ai, where 1 ≤ i ≤ 10 and 0 ≤ ai ≤ 10. In addition r satisfies the following condition: the number of ai equal to 1 is greater  or equal than l (where the dimension of the manifold M is either 2l or 2l+1). The definition of Dr[f](mod 1) and the combinatorial scheme which enables its computation is given in G. Graff and J. Jezierski [J. Fixed Point Theory Appl. 13 (2013), 63-84,  https://doi.org/10.1007/s11784-012-0076-1].
The data consists of 9 files: dim4_5.txt, dim6_7.txt, dim8_9.txt, dim10_11.txt, dim12_13.txt, dim14_15.txt , dim16_17.txt, dim18_19.txt, dim20_21.txt each of which contains pairs of lists in the form [ai: ai ≠ 0 and 1 ≤ i ≤ 10], [lower_bound, upper_bound], where the first place defines the powers of the prime numbers in the decomposition of r and the second gives the lower and upper bound for the invariant Dr[f](mod 1).
