A hierarchical spectral clustering and nonlinear dimensionality reduction scheme for detection of prostate cancer from magnetic resonance spectroscopy (MRS)
In this article the authors present a novel CAD scheme that integrates nonlinear dimensionality reduction (NLDR) with an unsupervised hierarchical clustering algorithm to automatically identify suspicious regions on the prostate using MRS and hence avoids the need to explicitly identify metabolite peaks.The published version of this article is available at: http://scitation.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=MPHYA6000036000009003927000001&idtype=cvips&prog=normalThis work was made possible via grants from the Wallace H.

Don (1825), after a detailed description reported “Hab. in Nepalia. Wallich” so referring to a Wallich’s collection. According to Stafleu and Cowan (1988: 38), Don’s <i>Prodromus</i> is based on Wallich’s specimens preserved at BM, CGE, FI, LINN (Smith’s Herbarium), and PR and “perhaps in various other herbaria”. I traced 7 Wallich’s specimens at BM, CAL, E, and K. Wallich (1829 –1849) mentioned two localities (Napalia and Pandua) in his “Numerical List” but Don (1825) described the genus based on specimens collected from Nepal. Hence, only 4 out of 7 specimens found (those collected in Nepal) can be considered as original material for <i>B. calycinum</i>. They are: K000568116 (http://apps. kew.org/herbcat/getImage.do?imageBarcode=K000568116), K000568119 (http://apps.kew.org/herbcat/getImage. do?imageBarcode=K000568119), BM000583343, and E00317572. Hara & Williams (1979: 53) reported “Wall. s.n., ann. 1819” as a type of <i>B. calycinum</i>. According to the Art. 7.11 of ICN (see also Prado <i>et al.</i> 2015) these two authors inadvertently lectotypified Don’s name.</p>Published as part of <i>Kumar, Anant, 2023, A new variety of Brachystemma calycinum (Caryophyllaceae) from West Bengal, India with notes on its typification, pp. 259-263 in Phytotaxa 598 (3)</i> on page 260, DOI: 10.11646/phytotaxa.598.3.8, <a href="http://zenodo.org/record/7970024">http://zenodo.org/record/7970024</a>
Hydrothermal areas, microbial mats and sea grass in Paleochori Bay, Milos, Greece
We collected orthophotos of Paleochori Bay, Milos, Greece in 2018 by drone (Orthophotos.zip) and stitched those images together to obtain a high-resolution, georeferenced photographic image (Paleochori_Composite_Photo.tif). This image was used for further processing in ArcGIS to generate a 1:3300 scale map of the seafloor in Paleochori Bay (tjom_a_1748131_sm0990.pdf) with native shapefiles and layer files (Shapefiles.zip), showing the distribution of white microbial mats, former microbial mats, sea grass and “normal” sand down to a depth of 15 m. The georeferenced photographic image allows to obtain GPS coordinates for any point of interest in Paleochori Bay and thus, allows to target specific locations for data collection, rather than resorting to vague site descriptions, as has been the practice in the past. With aid from the georeferenced photo of Paleochori Bay, 150 sea floor temperatures were measurements by Scuba divers (Temperature_measurments.xlsx) to evaluate the temperature distribution in the bay, in order to further the overall understanding of the hydrothermal system

Leaves opposite, decussate, petiolate or uppermost pair sessile; petioles (0−) 0.5−8 cm long, sulcate, pubescent; lamina elliptic-ovate to elliptic-lanceolate, uppermost pair ovate to broadly ovate, smaller in size, 1.4−10 × 0.9−4.4 cm, chartaceous, base unequal, rounded, subcordate, attenuate, or decurrent onto petiole when young, margin entire, apex shortly acuminate, pubescent and green above, tuberculate, glabrous and whitish beneath, veins camptodromous, midvein prominent, impressed above, prominent below, pubescent, lateral veins 5−7 pairs, otherwise same as mid vein. Inflorescences terminal, condensed racemes, 1–4 cm long, 4−12-flowered, pubescent. Flowers ca. 2 cm across; pedicels slender, 1−1.2 cm long, pubescent. Bracts triangular, 1.2–1.5 mm long, apex acuminate, margin ciliate persistent; bracteoles ovate-lanceolate, 0.5–0.7 mm long, apex acute, margin ciliate, persistent. Calyx 5-lobed, pubescent and glandular-hairy outside, glabrous inside; tube 1–1.5 mm long; lobes linear-lanceolate, 3−3.5 mm long, apex acute. Corolla infundibuliform, ventricose, white, with a light violet-purple blotch on the middle lobe of lower lip, glandular-hairy outside, glabrous inside; tube 2–2.3 cm long, base cylindrical for 1.5–1.7 cm long, throat 5–6 mm long; lobes 5, elliptic-ovate, 5−7 × 4–4.5 mm, apex obtuse. Stamens 4, didynamous, inserted at base of throat, slightly exserted; filaments white, slender, shorter pair 5−5.5 mm long, longer pair 8−8.5 mm long, connate at the base in pairs, glabrous; anthers white with a vertical violet-black band on the sides, oblong, 1.2–1.5 cm long, spurred at base, connective beyond the anther cells, glabrous. Ovary green, oblong or columnar, compressed, 1.2−1.5 mm long, papillose, basally surrounded by fleshy, dull white, nectariferous disc, 2-celled; ovules 2 in each cell; style white, filiform, 2.4–2.6 cm long, glabrous; stigma shortly 2-lobed, smooth. Capsules green, clavate, compressed, 1.4–2.2 cm long, dehiscent, densely glandular hairy. Seeds 4, suborbicular, flattened, ca. 3 mm across, tuberculate, rugose, dentate along margins, borne on ca. 2 mm long, hook-like retinacula. Phenology:—Flowering and fruiting from September to December. Habitat: — The new species grows along lakes in shady area at an elevation of about 10 m. The association includes Rivina humilis L., Ruellia tuberosa L., Cardiospermum halicacabum L., Mikania micrantha Kunth and Plumbago zeylanica L. and grasses etc. Distribution:—The species is distributed in Howrah, West Bengal, India so far. Etymology:—The new species is named after Dr Potharaju Venu, Former Senior Scientist of Botanical Survey of India, for his significant contribution to the taxonomy of Indian Acanthaceae. Notes:— The Indian species of the genus can be categorized in two groups on the basis of shape of corolla tube, i.e. Group 1 comprises three species Asystasia atroviridis Anderson (1867: 526), A. neesiana (Wallich 1830: 73) Nees (1832: 89), A. venui Anant Kumar, G. Krishna & Av. Bhattacharjee sp. nov. having cylindrical, shortly funnelshaped corolla tube upwards, and Group 2 having 10 species A. chelonoides Nees (1832: 89), A. crispata Bentham (1852: 647), A. dalzelliana Santapau (1948: 276), A. gangetica (Linnaeus 1756: 3) Anderson (1860: 235), A. indica H.J. Chowdhery & Av. Bhattacharjee (2006: 211), A. macrocarpa Nees (1832: 89), A. mysorensis (Roth 1821: 303) Anderson (1867: 524), A. pusilla C.B. Clarke (1889: 55), A. travancorica Beddome (1872: 39), and A. variabilis (Nees 1847: 165) Trimen (1895: 324) with tubular-ventricose corolla tube (FIGURE 1). Out of these, five species are endemic to India, e.g., A. crispata, A. dalzelliana, A. indica, A. pusilla, and A. travancorica. Lindau (1895) erected a new genus Asystasiella Lindau (1895: 326) to accommodate the species of Group one with two species, viz. A. neesiana and A. atroviridis, and it was considered to be different from Asystasia by having a narrow cylindric corolla tube and stachel pollen (spheroidal with spines). Ensermu et al. (1992) discussed the delimitation of the genus based on pollen morphology. Since, the genus Asystasia encompasses considerable variation in inflorescence form, corolla morphology, and pollen type, therefore, the genus Asystasiella was included within Asystasia (Manzitto-Tripp et al. 2022). The generic circumscription of Asystasia, Asystasiella, Mackaya and other related genera should be delimitated by molecular phylogenetic study along with pollen morphology. Das (1939: 408) incorrectly transferred these three species from Asystasia to Mackaya as M. atroviridis (Anderson 1867: 526) Das (1939: 448), M. macrocarpa (Nees 1832: 89) Das (1939: 447), and M. neesiana (Wallich 1830: 73) Das (1939: 447), respectively. However, the genus Mackaya is characterized by two fertile stamens without spurs and with two staminodes, while Asystasia has all four fertile stamens with spur at the base of anthers. Deng and Wu (2009: 308) stated that these three species were quite different from Mackaya in having four stamens and they preferred to place them in Asystasia rather than in Mackaya. Based on the above mentioned reasons the new species fits with Asystasia instead of Mackaya and hence, we are describing it here under Asystasia. The new species was wrongly identified as Asystasia chelonoides Nees by Chowdhery and Pandey (2007). However, it can be easily distinguished from Asystasia chelonoides by its long tubular-cylindrical corolla and densely flowered racemes. Comparison of diagnostic characters of the new species with its most allied species is provided in detail in Table 1. Additional specimens examined (Paratypes):— INDIA.
