Relativistic model of hidden bottom tetraquarks

The relativistic model of the ground state and excited heavy tetraquarks with hidden bottom is formulated within the diquark-antidiquark picture. The diquark structure is taken into account by calculating the diquark-gluon vertex in terms of the diquark wave functions. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.Comment: 6 page

Youtube Analytics Channel Visualization Results Using Google Data Studio and Klipfolio

Demonstrate the power of Big Data Analytics using Google Analytics as a platform work flow. First open the YouTube channel, then start recording of the channel analytics is done here automatically by Google. This data is exported from YouTube Analytics to Google sheets and then is fed to Google Analytics. After analyzes the data, it is now integrated with Google Data Studio and Klipfolio. Google Data Studio makes use of AI (Artificial Intelligence) insights techniques that can generate artificial intelligence and prediction-based report graphs which can be analyzed by the end user. In the future, not only YouTube, but any Google products or Google service data can be fed to Google Analytics and integrated in Google Data Studio for artificial intelligence based on Big Data Analytics

Superconductor-Insulator Transitions and Insulators with Localized Pairs

Two experiments are described which are related to the problem of localized Cooper pairs. Magnetic-field-tuned superconductor-insulator transition was studied in amorphous In--O films with onset of the superconducting transition in zero field near 2 K. Experiments performed in the temperature range T>0.3 K indicate that at the critical field, B=B_c, the first derivative of the resistance dR/dT is non-zero at T=0 and hence the scaling relations should be written in more general form. Study of the magnetotransport of high-resistance metastable alloy Cd-Sb on the insulating side of the superconductor-insulator transition revealed below 0.1 K a shunting condiction mechanism in addition to usual one-particle hopping. Possibility of pair hopping is discussed.Comment: 4 pages, 5 PS figures, uses psfig.sty; contribution to the Conference MESO-97, June 1997, Chernogolovka, Russi

Width of the Zero-Field Superconducting Resistive Transition in the Vicinity of the Localization Threshold

Resistive superconducting zero-field transition in amorphous In-O films in states from the vicinity of the insulator-superconductor transition is analyzed in terms of two characteristic temperatures: the upper one, $T_{c0}$, where the finite amplitude of the order parameter is established and the lower one, $T_c$, where the phase ordering takes place. It follows from the magnetoresistance measurements that the resistance in between, $T_c<T<T_{c0}$, cannot be ascribed to dissipation by thermally dissociated vortex pairs. So, it is not Kosterlitz-Thouless-Berezinskii transition that happens at $T_c$.Comment: 4 pages, 3 figure

Scale dependent superconductor-insulator transition

We study the disorder driven superconductor to insulator transition in amorphous films of high carrier-concentration indium-oxide. Using thin films with various sizes and aspect ratios we show that the `critical' sheet-resistance $R_{{\small \square}}$ depends systematically on sample geometry; superconductivity disappears when $R_{{\small \square}}$ exceeds $\approx6$k$\Omega$ in large samples. On the other hand, wide and sufficiently short samples of the same batch exhibit superconductivity (judged by conductivity versus temperature) up to $R_{{\small \square}}$ which is considerably larger. These results support the inhomogeneous scenario for the superconductor-insulator transition.Comment: Contribution to the proceedings of "Fluctuations and phase transitions in superconductors", Nazareth Ilit, Israel, June 10-14, 200

Final proposal to encode the Cuneiform script in the SMP of the UCS

This is a proposal to encode the Phoenician script in the international character encoding standard Unicode. This script was published in Unicode Standard version 5.0 in July 2006. The Phoenician script is an historic script, used to represent texts in Paleo-Hebrew, Archaic Phoenician, Phoenician, Early Aramaic, Late Phoenician cursive, Phoenician papyri, Siloam Hebrew, Hebrew seals, Ammonite, Moabite, and Punic. Although some scholars today use Square Hebrew to transliterate Paleo-Hebrew, the Phoenician script was included in Unicode to be able to represent the historic script directly

Scaling analysis of the magnetic-field-tuned quantum transition in superconducting amorphous In-O films

We have studied the magnetic-field-tuned superconductor-insulator quantum transition (SIT) in amorphous In-O films with different oxygen content and, hence, different electron density. While for states of the film near the zero-field SIT the two-dimensional scaling behaviour is confirmed, for deeper states in the superconducting phase the SIT scenario changes: in addition to the scaling function that describes the conductivity of fluctuation-induced Cooper pairs, there emerges a temperature-dependent contribution to the film resistance. This contribution can originate from the conductivity of normal electrons.Comment: 4 pages, 5 figures; accepted for publication in JETP Lett. 71 (4), 200
