A Bluetooth Scatternet for the Khepera Robot
No full textDu JL, Witkowski U, Rückert U. A Bluetooth Scatternet for the Khepera Robot. In: 4th International Symposium on Autonomous Minirobots for Research and Edutainment (AMiRE). Buenos Aires, Argentina; 2007: 189-195.Radio-based communication plays a vital role in multi-robot systems.
Bluetooth is an energy-efficient communication technology suited for resourcelimited mini-robots such as the Khepera. However, the maximum number of nodes in a Bluetooth piconet is limited, while scatternets - networks of piconets - have not been fully specified. In this paper we present a Bluetooth scatternet using Bluetooth communication sticks developed in our research group. In our solution, bridge nodes carrying two of such Bluetooth sticks are used to interconnect piconets. Beside the developed hardware, issues such as routing as well as topology control are addressed. Finally, data rate and latency measurements are presented for the implemented solution
Syvertsenia iberica Witkowski & Gomes 2013, sp. nov.
No full textSyvertsenia iberica Witkowski & Gomes sp. nov. (Figs 2–19) Valves linear with protracted to capitate apices, 21.4–28.6 (25.2 ± 2.9) µm long, 3.1–4.5 (3.7 ± 0.6) µm wide. Valves slightly arched about transapical axis. The mantle is shallow, except next to the process where a convex expansion of the valve mantle with an areolae situated above the process is observed. The whole valve surface is covered with areolae, except a small part of the valve in the middle which is close to the tubular process. The number of areolae in 10 µm varies between 17 and 20. Close to the process, there is a small oval area devoid of areolae (Figs 4, 6–8 and 11). The single tubular process is positioned on the extension of the valve mantle (Figs 3, 4, Figs. 6–8 and Fig. 10). The valve linkage consists of one row of marginal, short, Y-shaped linking spines at each side of the valve (Fig. 14). The row of linking spines terminates close to the ocelluli (Figs. 17 and 19). There are two ocelluli (with ca. 20 porelli each and small spines inside— Figs 16–19) set on the apices. The ocelluli are slightly displaced from the valve centre (Figs 10, 16–19). Type: ⎯ SPAIN. Ayamonte: Guadiana Estuary, sandy flat near the river mouth (Fig. 1B), station GS1 (37º11'41''N, 7º24'22''W, Fig 1C). Sample collected from surface sediment by Ana Isabel Gomes on the 26 th of May, 2010. Holotype SZCZ slide 18916, illustrated in Figures 6 and 7; isotype slide no. 13298/ ALGU in the ALGU Plant and Algae Collection (Fig. 2). Etymology: ⎯The specific epithet was chosen considering that Guadiana Estuary makes the border between the two countries that constitute the Iberian Peninsula. Distribution and ecology: ⎯Thus far, known only from the type habitat area i.e. Guadiana Estuary, stations GS1, GS2 and GS18 (Fig. 1C). In the referred stations, the salinity of the sediment interstitial water ranges between 19.93 (GS1) and 30.74 g /Kg (GS18) while pH values varies from 7.27 (GS18) to 7.58 (GS2). The substrate grain-size preference varies between medium silt (GS18) and fine sand (GS2). In terms of organic carbon percentage it ranges from 0.36 % (GS2) to 3.40 (GS18). Table 3 presents in detail the physicochemical parameters measured at each sampling station. The river water column adjacent to the sampling stations presents a mean salinity of 26.43 ± 11.13 g /Kg, a pH of 8.20 ± 0.27, dissolved oxygen of 98 ± 19.48 % and a mean temperature of 17.88 ± 5.13º C.Published as part of Gomes, Ana, Witkowski, Andrzej, Dąbek, Przemysław, Boski, Tomasz, Moura, Delminda, Szkornik, Katie & Kurzydłowski, Krzysztof, 2013, Syvertsenia iberica (Cymatosiraceae): a new estuarine diatom genus characterized by the position of its process, pp. 25-36 in Phytotaxa 142 (1) on page 30, DOI: 10.11646/phytotaxa.142.1.3, http://zenodo.org/record/509988

Case Report: melanoma and melanocytic nevus differentiation with reflectance confocal microscopy. [v1; ref status: indexed, http://f1000r.es/5mr]
No full textHistorically, melanoma has been typically diagnosed by naked-eye examination and confirmed with invasive biopsy. However, recently the use of reflectance confocal microscopy enables non-invasive bedside diagnosis of clinically equivocal lesions. We present a case in which reflectance confocal microscopy was used to evaluate two skin lesions in the same patient confirming the diagnosis of a melanoma and potentially avoiding invasive biopsy in the second benign melanocytic lesion. Clinicians should be aware of the availability of new non-invasive technologies that can aid in early diagnosis of malignant skin tumors and potentially reduce the number of benign lesion excisions
