This article is devoted to the problem of novelty in embedded art. Exciting possibilities of microelectronics for visual art are considered. Implementations of available microcontrollers, sensors and actuators are given. A new kind of interactions between spectators and artworks with embedded electronics was investigated. Special attention is paid to the effect of emergence, which is generated by this interaction. Computational artwork is being considered in a new unconventional context. An aesthetic difference between the deterministic and nondeterministic algorithms was shown. The combination of acrylic paintings with light-emitting diodes (LEDs) was systematically studied to give useful recommendations for an artistic community. Produced artifacts were demonstrated at exhibitions and were used to teach students at the university and VHS Freiburg, Germany. The results showed a great public interest in embedded electronic systems and a tremendous theoretical and practical perspective for the permanently developing contemporary art.

The COVID-19 pandemic presented enormous data challenges in the United States. Policy makers, epidemiological modelers, and health researchers all require up-to-date data on the pandemic and relevant public behavior, ideally at fine spatial and temporal resolution. The COVIDcast API is our attempt to fill this need: Operational since April 2020, it provides open access to both traditional public health surveillance signals (cases, deaths, and hospitalizations) and many auxiliary indicators of COVID-19 activity, such as signals extracted from deidentified medical claims data, massive online surveys, cell phone mobility data, and internet search trends. These are available at a fine geographic resolution (mostly at the county level) and are updated daily. The COVIDcast API also tracks all revisions to historical data, allowing modelers to account for the frequent revisions and backfill that are common for many public health data sources. All of the data are available in a common format through the API and accompanying R and Python software packages. This paper describes the data sources and signals, and provides examples demonstrating that the auxiliary signals in the COVIDcast API present information relevant to tracking COVID activity, augmenting traditional public health reporting and empowering research and decision-making.

A hoard of 40 early medieval drachms appeared at the Sunday numismatic market in Tashkent in the spring of 2009. The man who brought these coins to the market was reticent about the exact place where this hoard had been found. He said only that the coins were found \"at the border between Uzbekistan and Tadjikistan,\" suggesting they are from eastern/Samarqandian Sogd, since western/Bukharan Sognd does not border on modern Tadjikistan.

This paper examines several bronze coins of the Samarqandian kings issued in the last third of the sixth-first third of the seventh century AD. Using limited information provided by the Chinese chronicle and by the coins themselves, the authors offer an identification of two kings portrayed on these coins, and the tentative date of their reign. The reading of the names of these kings is proposed as \"Turanin\" and \"Qutluqchiq\".

This paper discusses a recently discovered Khwārazmian drachm minted by the ruler Ja'far b. Malik on the model of late drachms of the Khwārazmshāh Azkājvār-'Abdallāh in the time of the Tahirid govenor 'Abd Allāh b. Ṭāhir (AH 213-30/AD 828-45) and some late drachms of the Khwārazmshāh Azkājvār-'Abdallāh.

A rotifer with a body size of 300 um, having a goblet-shaped body with a funnel-like structure lined with cilia, divided into two symmetrical parts capable of generating two circular water currents, was isolated from the integrated sample collected from three freshwater bodies in the mountainous Crimea region. The rotifer has a discernible rostrum on the head and two spurs on the foot, which enable its locomotion on the substrate. The mobile mastax, stomach, and cloaca are visible. The discovered morphoty pe 15 similar to the rotifer Philodina megalotrocha (Ehrenberg, 1832), which is widely distributed in freshwater habitats across Europe. The isolated rotifer did not respond to artificial mechanical and electrical stimuli but instantly reacted to what was theorized to be potentially dangerous stimuli, such as the abrupt touching of its cilia with a foreign object. Additionally, the animal exhibited a negative response to violet-blue light (405 nm). The rotifer stopped moving its cilia, extended its rostrum, attempted to crawl away, and ultimately swam away from the light source. Opsin-like proteins, structurally corresponding to the opsins of other multicellular organisms, have been identified using bioinformatics analysis in rotifers with known EDN: XTVUDL УДК 595.18-118(282.247.34) Response of the Rotifer Philodina cf. megalotrocha (Ehrenberg, 1832) from Water Bodies in the Mountainous Crimea to Artificial Physical Stimuli Ekaterina V.

The paper discusses an anonymous bronze Sodgian coin of heretofore unknown type from the vicinity of Afrasiyab (fortified central part of ancient Samarqand), having emblems of the Samarqand royal Unash dynasty and minted in the time of interregnum. The authors date this coin to AH 56 (25 November 675-13 November 676), when according to the Arab chronicle there was no king in Samarqand.

Previously unknown drachms allow us to give new readings for the names of some Khwarezm-shahs: šk'm/'čk'm and k'nyr. A pronounced difference between the faces on coins with the name k'nyr suggests that there were two Khwarazmshahs of this same name. Approximate times of the reign of these rulers and their succession are established, based on the metrology and typology of their coins.
