Abstract This paper attempts to show that manufacture of Micoquian bifacial backed tools was structured. Data for this study were collected using a comprehensive analysis of artefacts from the site Pietraszyn 49a, Poland, which is dated to the beginning of Marine Isotope Stage 3. Based on the whole data set, it was possible to distinguish four stages of the manufacturing process. During manufacturing, both mineral hammer and organic hammer were used. The tools were usually shaped due to distinct hierarchization of faces. The study has also shown that the shape of bifacial tools from Pietraszyn 49a is very similar to the other Micoquian examples from central Europe. The ways of shaping of some tools are finding their counterparts also in the Early Upper Palaeolithic inventories, but the similarities are rather limited to the narrow range of preparation of bifacial form.

Since their initial discovery in the nineteenth century, human figurines have formed a noticeable part of the artistic record of the 30,000 years of the European Upper Palaeolithic. Some figurines—particularly the ‘Venuses’ of the Mid-Upper Palaeolithic (Gravettian sensu lato)—have long served as icons of Upper Palaeolithic cultural achievement. This chapter reviews our current understanding of figurines of western and North Central Europe. Their first manifestation is with a few enigmatic examples during the Early Upper Palaeolithic (Aurignacian) of southwest Germany. A far more visible and geographically widespread manifestation comes with the Mid-Upper Palaeolithic Venus figurines, and a similarly widespread occurrence comes with the highly schematic side-profile outlines of the Gönnersdorf type, which belong to the Middle and Late Magdalenian. The history of interpretation and current thinking of these figurine horizons is discussed in this chapter, which should be read in conjunction with Chapter 30 (Farbstein).

Having lately returned from Czecho-Slovakia, where I was attending an Anthropological Congress and studying museum collections, I thought perhaps it might interest members of the P.S.E.A. to have a note on what appears to be the succession of prehistoric cultures in that country.There seems to be nothing so far found corresponding to our Lower Palæolithic or earlier industries. It is true that there is one solitary lump of flint, roughly chipped, with large flake-scars and an ochreous patina that has been claimed as Lower Palæolithic in date, but it is really very little to go on. A poor kind of Mousterian, mostly not made of good flint, seems fairly common in Moravia although it has not been found near Prague. On the other hand, many of the tools in an undoubted Upper Palæolithic series recall by their technique and shape the industry of La Quina.

Abstract. A third Kirkbyites species, K. hercynicus sp. nov., is described from the early Upper Devonian (early Famennian) of the Harz Mountains (Central Europe) to join the other two known species of the genus Kirkbyites upsoni Johnson, the Upper Carboniferous type species from Nebraska (U.S.A.), and the late Upper Devonian Kullmannissites? solus Becker from N Spain (W Europe). Its biotype indicative carapace features, characteristic of marine low-energy palaeo-environments, place Kirkbyites Johnson, 1936 (Ostracoda, Palaeocopida, Kirkbyacea, Amphissitidae) into Becker’s “Thuringian” ecotype.

New radiocarbon dates from four Moravian and Bohemian sites are presented and linked to previous work on the depositional contexts of human fossils at similar sites in the region. Whilst dates from Mladeč confirm its early Upper Palaeolithic age, the chronologies of the other three sites require revision.

The analysis of a data set of observation for Vietnamese banks in period from 2011 - 2015 shows how Capital Adequacy Ratio (CAR) is influenced by selected factors: asset of the bank SIZE, loans in total asset LOA, leverage LEV, net interest margin NIM, loans lost reserve LLR, Cash and Precious Metals in total asset LIQ. Results indicate based on data that NIM, LIQ have significant effect on CAR. On the other hand, SIZE and LEV do not appear to have significant effect on CAR. Variables NIM, LIQ have positive effect on CAR, while variables LLR and LOA are negatively related with CAR.

Abstract The decays D → K−π+π+π− and D → K−π+π0 are studied in a sample of quantum-correlated $$ D\overline{D} $$ D D ¯ pairs produced through the process e+e− → ψ(3770) → $$ D\overline{D} $$ D D ¯ , exploiting a data set collected by the BESIII experiment that corresponds to an integrated luminosity of 2.93 fb−1. Here D indicates a quantum superposition of a D0 and a $$ {\overline{D}}^0 $$ D ¯ 0 meson. By reconstructing one neutral charm meson in a signal decay, and the other in the same or a different final state, observables are measured that contain information on the coherence factors and average strong-phase differences of each of the signal modes. These parameters are critical inputs in the measurement of the angle γ of the Unitarity Triangle in B− → DK− decays at the LHCb and Belle II experiments. The coherence factors are determined to be RK3π = $$ {0.52}_{-0.10}^{+0.12} $$ 0.52 − 0.10 + 0.12 and $$ {R}_{K{\pi \pi}^0} $$ R K ππ 0 = 0.78 ± 0.04, with values for the average strong-phase differences that are $$ {\delta}_D^{K3\pi }=\left({167}_{-19}^{+31}\right){}^{\circ} $$ δ D K 3 π = 167 − 19 + 31 ° and $$ {\delta}_D^{K{\pi \pi}^0}=\left({196}_{-15}^{+14}\right){}^{\circ} $$ δ D K ππ 0 = 196 − 15 + 14 ° , where the uncertainties include both statistical and systematic contributions. The analysis is re-performed in four bins of the phase-space of the D → K−π+π+π− to yield results that will allow for a more sensitive measurement of γ with this mode, to which the BESIII inputs will contribute an uncertainty of around 6°.
