Potential diagnostic utility of recombinant Toxoplasma gondii proteins for detecting anti-Toxoplasma gondii IgG antibodies in feline serum samples

Bartłomiej Ferra
Toxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, and is a parasitic disease that occurs in all warm-blooded animals, including humans. Toxoplasmosis is one of the most common parasitic diseases of animals and results in reproductive losses. Diagnosis of toxoplasmosis is currently based on serological assays using native antigens to detect specific anti-T. gondii antibodies. Continuous development of scientific disciplines, such as molecular biology and genetic engineering, allows for the production of new recombinant antigens...

Database of the minimal sets of Lefschetz periods for Morse-Smale diffeomorphisms of a connected sum of g tori

Grzegorz Graff & Adrian Myszkowski
Morse–Smale diffeomorphisms, structurally stable and having relatively simple dynamics, constitute an important subclass of diffeomorphisms that have been carefully studied during past decades. For a given Morse–Smale diffeomorphism one can consider “Minimal set of Lefschetz periods”, which provides the information about the set of periodic points of  a considered map, as it is the subset of its minimal periods. The dataset consists of 20 files indexed by numbers g=1,...,20. Each file provides all minimal sets...

Video of LEGO bricks on conveyor belt - slopes, arcs and rainbows

Tomasz Boiński
The set contains videos of LEGO bricks (slopes, arcs and rainbows) moving on a white conveyor belt. The videos were prepared for training neural network for recognition of LEGO bricks. The bricks were separated as much as possible and in most cases they should not overlap. The images were taken from different sides by stationary camera located over the final conveyor belt.   The videos were recorded using Huawei p20 Pro camera (1920x1080 resolution, H.264...

Construction, production and evaluation of the diagnostic utility of a recombinant Toxoplasma gondii chimeric antigen SAG1-SAG2-GRA6

Bartłomiej Ferra
The intracellular parasite Toxoplasma gondii has the ability to infect a wide range of warm-blooded animals, including humans. Currently, diagnosis of toxoplasmosis is based mainly on the use of the native antigens in enzyme immunoassay which allow for detection of IgG, IgM and IgA antibody classes. However, in some cases the performed studies give the ambiguous results. Moreover, the commercially available diagnostic tests due to its price are not generally applicable in the serodiagnosis of...

Testing impedance analyzer with potentiostat using RC model with Si diode at 200 mV

Grzegorz Lentka
The dataset presents impedance spectrum non-linear RC model with diode presented in the figure below. This model was used as a test engine of the impedance analyzer with potentiostat described in the referenced paper. When changing the DC polarisation of the model the non-linear phenomena could be observed. Thanks to this, the model can be used as a test engine for evaluation of the analyzer in the non-linearity conditions. The impedance spectrum frequency range (10...

Electronic transition dipole moment functions of the first singlet Sigma ungerade plus and first triplet Sigma gerade plus states of the Lithium dimer

Patryk Jasik & Józef Sienkiewicz
Electronic transition dipole moment functions (ETDMF) of the first singlet Sigma ungerade plus (1sSu+) and first triplet Sigma gerade plus (1tSg+) states have been calculated for the Lithium dimer. ETDMFs are needed in understanding processes like photodissociation, photoassociation, cooling, and trapping of molecules. The results of the four ETDMFs 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...
