Consumption patterns and living conditions inside Het Steen, the late medieval prison of Malines (Mechelen, Belgium)

Excavations at the Main Square (Grote Markt) of Malines (Mechelen, Belgium) have unearthed the building remains of a tower, arguably identifiable as the former town prison: Het Steen. When this assumption is followed, the contents of the fills of two cesspits dug out in the cellars of the building illustrate aspects of daily life within the early 14th-century prison. An integrated approach of all find categories, together with the historical context available, illuminates aspects of the material culture of the users of the cesspits, their consumption patterns and the living conditions within the building

De visserskaai te Oostende (prov. West-Vlaanderen): archeologie van een in de 17de eeuw zwaar geteisterde stad

The Institute for the Archaeological Heritage of the Flemish Community (IAP) has, in close collaboration with the town of Ostend, carried out archaeological excavations during the construction works of the car park below the Visserskaai at Ostend from September 1998 till February 1999. This archaeological work mainly produced information on the eastern ramparts of Ostend and their evolution from the 16th century onwards together with information on the material culture of the inhabitants of Ostend during this same period. The town of Ostend had no defences until late in the 16th century as initial construction work for the defences only started in 1572 when the town came into northern hands. In the beginning of the 17th century Ostend managed to withstand successfully, with its newly built ramparts, for three years an overwhelming Spanish army siege. This was only possible thanks to the fact that the Spaniards never managed to seal of Ostend completely from the sea. As a result, victuals and soldiers arrived continuously at Ostend during the siege. It was only after the arrival of Spinola in the besieging camp, at the end of 1603, that Ostend was gradually forced to surrender. At the bottom of the excavated car park trench, some 4 m below the actual street level, wooden structures of the earthen ramparts were preserved (figs. 4-5). The presence of these con- firms historical data about the use of wood to strengthen the earthen ramparts. The excavations however documented mainly features from 2 bastions, the Peckels bastion and the Spanish bastion (fig. 2-3). Human burials and a gunpowder-magazine (figs. 7, 8, 10, 12) were uncovered in the Peckels bastion and human burials and an open-air rainwater reservoir were detected in the Spanish bastion. The human burials are studied elsewhere in this volume together with other post-medieval burials from Ostend recently discovered outside regular cemeteries. Archaeological material found in connection with the gunpowder-magazine in the Peckelf bastion dates from the 2nd half of the 16th /1st half of the 17th century (figs. 6,9,13-15) and suggests that the construction of this gunpowder-magazine? has to be situated somewhere in the middle of the 17th century, in other words in the period when the town defences of Ostend were adapted to new standards after the above- mentioned siege. A typical object related to the siege is a funnel-shaped gunpowder-flask in a copper-alloy (fig. 6). The inner wall of the gunpowder-magazine was erected on a framework of horizontal wooden beams, which were themselves resting on vertically placed and sharpened beams, mainly in oak (fig. 8). A dendrochronological analysis of the vertically placed beams produced a terminus post quem, which is far too early to be of any help in the discussion on the gunpowder-magazine. The technical differences between the inner and outer wall of the gunpowder-magazine suggest at least 2 phases for this building. The above-mentioned ceramics consist of redwares, Rhenish stone- wares a.o. Raeren, maiolicas, Weser slipwares, olive jars from Seville and some whitewares with green or yellow glaze. The archaeological material from the open- air rainwater reservoir in the Spanish bastion dates from the 2nd half of the 17th/1st half of the 19th century but mainly from the 18th century (figs. 16-32). The collection of ceramics from this context is largely dominated by tablewares. Among these stonewares are nearly missing and replaced by faience, china and industrial white- wares (pearl and cream wares). Maiolica has been nearly completely replaced by faience. Maiolicas remain in fact only important as wall-tiles. The collection contains some olive jars from Seville, a bowl from Dèsvres and a few products from Beauvais. The collection of china mainly consists of cups and small dishes in blue and white china. The china has been brought to Ostend in great quantities in the 18th century, first by the Ostend Company and later by mariners from Ostend in Foreign Service, mainly as ship's ballast. Besides ceramics this context also produced several finds in leather, glass, stone and metal. The leather finds mainly consist of shoes. The glass collection is largely dominated by cylindrical and globular bottles of which one was still intact including its cork (fig. 26: 1). Metal is represented by 22 cast iron cannon balls (fig. 28) and by a standard measure for bottles from an unidentified town inspector of measures and weights of Ostend with GS initials (fig. 27: 8). Small quantities of animal remains were found dispersed over many contexts within the site's stratigraphy. Only three of them are meaningful: a deposit found under the floor of the gunpowder-magazine (table 1: context A), an assemblage excavated in leveling layers within the Peckels bastion (table 1: context B), and material found in the water reservoir in the Spanish bastion (table 1: context C). All connections consisted of larger material; sieved samples did not yield meaningful numbers of smaller animal remains. Context A dates from the second half of the 16th to the first half of the 17th century and consists of consumption refuse: marine molluscs, marine fish bones, bird bone and the remains of cattle, sheep and pig. Context B is contemporaneous to context A and also represents consumption refuse with a similar composition. Remarkable are only a series of vertebrae of a large specimen of ling, a fish that must have been caught in northern waters, and a number of skeletal elements of a gurnard species. Context C has a younger date (second half of the 17th century to the first half of the 19th century) and has a mixed origin in terms of the taphonomy of the animal remains. Not only consumption refuse is present but also parts of the skeletons of at least four dogs and a horse. It is possible that all three contexts represent secondary refuse; in any case their provenance remains unknown. The material certainly has limited value for the interpretation of former consumption patterns. A feature of special interest is the presence of a few cowrie shells. Several aspects of the material culture reflect the maritime character of the town: the presence of several imports such as olive jars from Seville and specific objects as a token in lead (fig. 13: 16) probably used by skippers for the payment of fees and/or tolls. The presence of an important percentage of china and of some cowrie shells is probably related to the activities of the Ostend Company in the l8th century. The pottery discovered from both contexts (2nd half 16th century/ 1 st half 17th century and 2nd half 17th century/ 1st half 19th century) follows the general trends described for post-medieval Flanders

Een 18de-eeuwse wraksite op de Buiten Ratel-zandbank (Belgische territoriale wateren): 1. Multidisciplinair onderzoek van het vondstenmateriaal

In 1996 werd op de Buiten Ratel-zandbank, op 9 mijl van de kust, ter hoogte van Koksijde, een houten scheepswrak gelokaliseerd. Het werd onderzocht door een groep sportduikers, met de naam NATA. Jarenlange verkenning van de wraksite leverde talrijke vondsten op. In 2003 zochten de duikers steun bij het toenmalige IAP (Instituut voor het Archeologisch Patrimonium), nu Vlaams Instituut voor het Onroerend Erfgoed (VIOE), om het onderzoek en de conservatie op wetenschappelijke basis verder te zetten. Het VIOE ontfermde zich over het onderzoek van de tot nu toe geborgen materiële resten van de wraksite. Het eerste hoofdstuk van het artikel geeft een overzicht van de observaties van de wraksite via duikonderzoek en via gespecialiseerde technieken vanop een onderzoeksschip. In hoofdstuk 2 worden de objecten beschreven, hun betekenis aan boord van het schip besproken, evenals hun datering en herkomst. Hoofdstuk 3 brengt alle informatie samen en geeft aan wat er in de toekomst nog aan onderzoek kan gebeuren

A Bayesian approach to modelling heterogeneous calcium responses in cell populations

Calcium responses have been observed as spikes of the whole-cell calcium concentration in numerous cell types and are essential for translating extracellular stimuli into cellular responses. While there are several suggestions for how this encoding is achieved, we still lack a comprehensive theory. To achieve this goal it is necessary to reliably predict the temporal evolution of calcium spike sequences for a given stimulus. Here, we propose a modelling framework that allows us to quantitatively describe the timing of calcium spikes. Using a Bayesian approach, we show that Gaussian processes model calcium spike rates with high fidelity and perform better than standard tools such as peri-stimulus time histograms and kernel smoothing. We employ our modelling concept to analyse calcium spike sequences from dynamically-stimulated HEK293T cells. Under these conditions, different cells often experience diverse stimuli time courses, which is a situation likely to occur in vivo. This single cell variability and the concomitant small number of calcium spikes per cell pose a significant modelling challenge, but we demonstrate that Gaussian processes can successfully describe calcium spike rates in these circumstances. Our results therefore pave the way towards a statistical description of heterogeneous calcium oscillations in a dynamic environmen
