We use quantitative ethnobotanical data to compare the usefulness of six floristically distinct forest types mestizo people at Tambopata, southeast Peru. aim evaluate which are most useful, and why. Ethnobotanical were collected with informants in inventory plots analyzed using a new technique that uses two‐tier calculation process derive an “informant indexed” estimate each species’ value. Use values estimated based on degree consistency between repeated interviews informant different...
This paper studies convolutional neural networks (CNN) to learn unsupervised feature representations for 44 different plant species, collected at the Royal Botanic Gardens, Kew, England. To gain intuition on chosen features from CNN model (opposed a ‘black box’ solution), visualisation technique based deconvolutional (DN) is utilized. It found that venations of order have been uniquely represent each species. Experimental results using these with classifiers show consistency and superiority...
AV1 is an emerging open-source and royalty-free video compression format, which jointly developed finalized in early 2018 by the Alliance for Open Media (AOMedia) industry consortium. The main goal of development to achieve substantial gain over state-of-the-art codecs while maintaining practical decoding complexity hardware feasibility. This paper provides a brief technical overview key coding techniques along with preliminary performance comparison against VP9 HEVC.
Google has recently finalized a next generation open-source video codec called VP9, as part of the libvpx repository WebM project (http://www.webmproject.org/). Starting from VP8 released by in 2010 baseline, various enhancements and new tools were added, resulting next-generation VP9 bit-stream. This paper provides brief technical overview along with comparisons other state-of-the-art codecs H.264/AVC HEVC on standard test sets. Results show to be quite competitive mainstream codecs.
The AV1 video compression format is developed by the Alliance for Open Media consortium. It achieves more than a 30% reduction in bit rate compared to its predecessor VP9 same decoded quality. This article provides technical overview of codec design that enables performance gains with considerations hardware feasibility.
VP8 is an open source video compression format supported by a consortium of technology companies. This paper provides technical overview the format, with emphasis on its unique features. The also discusses how these features benefit in achieving high efficiency and low decoding complexity at same time.

Abstract Aim Dioscorea (Dioscoreaceae) is a predominantly pantropical genus (< 600 species) that includes the third most important tropical tuber crop and species of pharmacological value. Fossil records from both Northern Southern Hemispheres were used to test hypotheses about origin , examine potential macroevolutionary processes led its current distribution. Location Pantropical Methods Divergence times estimated using comprehensive phylogeny group published date based on plastid...
It has been hypothesized that regulatory control in the respiratory system is state dependent. According to this view instability during sleep onset a consequence of repeated fluctuations arousal state. However, these speculations are based primarily on measurements stable sleep, not itself. The aim present study was assess changes ventilation and gas tensions as function Twenty-one subjects (12 males 9 females, mean age 20 yr) were assessed over an average 11.3 onsets. subject's classified...
Relationships of Dioscoreales are examined by combined analysis three molecular data sets (plastid rbcL, atpB and nuclear 18S rDNA genes) a morphological set. The corroborates narrow circumscription Dioscoreales, which includes Burmanniaceae Thismiaceae in the order, also indicates that Nartheciaceae closely related. thus comprise distinct clades: well-supported 'core Dioscoreales' clade (Dioscorea, Trichopus, Avetra, Tacca Stenomeris), Burmanniaceae–Thismiaceae Nartheciaceae. improvement...
Abstract Analyses of morphological and molecular characters for Dioscoreales Hook. f. (Chase & al., 1995b; Caddick 2000a; 2002) have redefined the order, which now comprises three families, Burmanniaceae, Dioscoreaceae, Nartheciaceae. Since recent analyses data sets (Caddick indicated wellsupported relationships within Dioscoreaceae R. Br., a formal reclassification family is presented here. contain four distinct genera, Dioscorea, Stenomeris, Tacca (previously in Taccaceae), Trichopus...
A 16-bit 125 MS/s pipeline analog-to-digital converter (ADC) implemented in a 0.18 ¿m CMOS process is presented this paper. SHA-less 4-bit front-end used to achieve low power and minimize the size of input sampling capacitance order ease drivability. The ADC includes foreground factory digital calibration correct for capacitor mismatches dithering that can be optionally enabled improve small-signal linearity. This achieves an SNR 78.7 dB, SNDR 78.6 dB SFDR 96 with 30 MHz signal, while...
Abstract Herbarium specimens are a vital resource in botanical taxonomy. Many herbaria undertaking large‐scale digitization projects to improve access and preserve delicate specimens, doing so creating large sets of images. Leaf characters important for describing taxa distinguishing between them they can be measured from herbarium specimens. Here, we demonstrate that images analysed using suitable software leaf extracted automatically. We describe low‐cost process use create set 1895 Tilia...
Whole genome duplication (WGD) events are common in many plant lineages, but the ploidy status and possible occurrence of intraspecific variation is unknown for most species. Standard methods determination chromosome counting flow cytometry approaches. While approaches typically use fresh tissue, an increasing number studies have shown that recently dried specimens can be used to yield data. Recent started explore whether high-throughput sequencing (HTS) data assess levels by analysing...
Yams (Dioscorea spp.) are a multispecies crop with production in over 50 countries generating ~50 MT of edible tubers annually. The long-term storage potential these is vital for food security developing countries. Furthermore, many species important sources pharmaceutical precursors. Despite attributes as staple crops and high-value chemicals, Dioscorea spp. remain largely neglected comparison to other tuber tropical agricultural systems such cassava (Manihot esculenta) sweet potato...
In 2018, the Alliance for Open Media (AOMedia) finalized its first video compression format AV1, which is jointly developed by industry consortium of leading technology companies.The main goal AV1 to provide an open source and royalty-free coding that substantially outperforms state-of-the-art codecs available on market in efficiency while remaining practical decoding complexity as well being optimized hardware feasibility scalability modern devices.To give detailed insights into how...
Abstract The Checklist of the Vascular Plants Republic Guinea (CVPRG) is a specimen-based, expert-validated knowledge product, which provides concise synthesis and overview current on 3901 vascular plant species documented from (Conakry), West Africa, including their accepted names synonyms, as well distribution status within (indigenous or introduced, endemic not). CVPRG generated automatically Collections Database Names Backbone Database, both developed maintained at Royal Botanic Gardens,...
Following recent phylogenetic studies of the families and genera Dioscoreales, identification monophyletic infrageneric taxa in pantropical genus Dioscorea is a priority. A analysis based on sequence data from plastid genes rbcL matK presented, using 67 species covering all main Old World selected New lineages. The used 14 outgroup taxa, including Trichopus Gaertn., Tacca J.R. & G. Forster, Stenomeris Planch., Burmannia L. Thismia Griff. findings are: a) that clade rhizomatous sister to rest...
