Gun and cash images
No full textThe dataset contains two datasets, which record 200/600 images.
'GunCash80X80NO200.mat' contains one type of gun and cash
'3gun80X80No600.mat' contains three types of gun and cash
The data format is matlab mat file, which can be loaded and displayed through the m file "load_GunCash_plot.m".
All the images are recorded as 80x80 images, but each image is recorded as a 6400x1 vector.
After load the file into matlab, you will find the file "alldata", which is 6402xN and
the sample number N equals 200 or 600.
Note that the last two rows of "alldata" are the labels of the images.
The 6401 row is the label(1/-1) to indicate the existence of a gun,
The 6402 row is the label(1/-1) to indicate the existence of a cash note.
We use a webcam to record images, which may depict a gun and/or cash (dollar notes).
The presence or absence of a gun is the public hypothesis, and the presence or absence of cash is the private hypothesis.
The gun and the cash are randomly translated and rotated in each 80x80 grayscale image.
The target is to detect the public hypothesis and make the private hypothesis cannot be detected
Neogergithoides Sun, Meng & Wang
No full textNeogergithoides Sun, Meng & Wang, gen. nov. Type species: Neogergithoides tubercularis sp . nov. by monotypy Description. Body hemispherical. Head with eyes distinctly narrower than pronotum. Vertex more or less hexagonal, tricarinate, 1.7 times longer than broad, anterior margin weakly convex at middle, posterior margin shallowly emarginate, disc depressed. Frons smooth, 1.8 times longer than broad, anteriorly truncate and moderately produced above eyes, slightly convex and narrowed towards clypeus, disk elevated with median carina; lateral margin clearly carinated. Clypeus elongate and triangulate, strongly elevated at disc, median carina present. Rostrum long, reaching post-trochanters. Eyes oval, ocelli present. Pronotum short, about half of vertex in mid-line, anterior margin convex onwards between eyes, with two central pits at disc, median carina present or obsolete, posterior margin elevated. Mesonotum more or less triangular with median and lateral carinae, with two pits along each lateral margin. Tegula small. Tegmen longer than broad, semicoriaceous and without claval suture, approximately 2.0 times longer in midline than wide at widest part, veins distinct and reticulate. Wing translucent, veins distinct and netlike, longer than half length of tegmen. Legs moderately long, not dilated; lateral margin of hind tibia with two teeth. Spinal formula of hind leg 6–9 – 2. Male genitalia. Anal segment in dorsal view mushroom-shaped. Pygofer in profile with dorsolateral angles strongly produced. Aedeagus slightly curved downward medially, with dorsal, lateral and ventral lobes, two short sword-like processes near middle. Genital styles in lateral view subtriangular, caudo-ventral angle rounded. Capitulum of style, in dorsal view, with two obtuse apical processes, and large lateral tooth. Female genitalia. Sternite VII with apical margin distinctly convex at middle. Anal segment in dorsal view oval-like. Anterior connective laminae of gonapophysis VIII nearly quadrilateral, with three nearly parallel teeth at apical margin; lateral margin with three small teeth with carinae at apex. Posterior connective laminae of gonapophyses IX nearly square in lateral view, lateral fields flat, median field wide and single. Gonoplac nearly quadrilateral, in dorsal view, fused at base and forked at apical half along dorsal margin. Remarks. The new genus is placed into the tribe Hemisphaeriini by the following combination of characteristics: body hemispherical; head with eyes narrower than pronotum; tegmen coriaceous and relatively thick, without claval suture; wing developed, and shorter than tegmen; lateral margin of hind tibia with two teeth. This new genus resembles Gergithoides Schumacher but differs from the latter by the following characters: 1) ocelli present, absent in Gergithoides; 2) vertex with tricarinate, about 1.7 times longer than wide, in Gergithoides, vertex with median carina or not, almost as long at base as wide in middle line; 3) frons without any tubercule and elevated at disc, posterior margin of pronotum with indistinct tubercules, in Gergithoides, frons with numerous tubercules along lateral margin and flat at disc, anterior and posterior margin of pronotum with distinct tubercules; 4) tegmen with a brown stripe along black anterior and apical margins, and anterior margin moderately convex at one third of base, Gergithoides without such stripe and anterior margin arc; 5) aedeagus with two short sword-like processes in basal half, Gergithoides with two processes at apical half. This new genus is also similar to Macrodaruma Fennah, but can be separated from the latter by the following characters: 1) vertex more or less hexagonal, slightly produced, in Macrodaruma, vertex almost trapezoidal and strongly produced, tapering; 2) pronotum with indistinct median carina, absent in Macrodaruma; 3) frons with lateral margin elevated, in Macrodaruma, lateral margin flat; 4) aedeagus with two short sword-like processes apex directed dorsally near middle, the Macrodaruma with two short processes apex directed basally at base. The similarity of some characters of the new genus, particularly the presence of the median carina on the frons, indicates that it is probably closer to Gergithoides, Macrodaruma, Mongoliana and Choutagus than other genera in the subfamily Hemisphariini, but it needs to be verified based on further phylogenetic research by using molecular and morphologic data as well. Etymology. The generic name “ Neogergithoides ” refers to the strong resemblance to Gergithoides. The genus is feminine in gender.Published as part of Sun, Yanchun, Meng, Rui & Wang, Yinglun, 2012, Neogergithoides, a new genus with a new species from China (Hemiptera: Issidae), pp. 42-53 in Zootaxa 3186 on pages 43-44, DOI: 10.5281/zenodo.28000
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
