For comparative purposes, important diagnostic features of <i>Zorotypus medoensis</i> from the type locality are figured (Fig. 6). Both <i>Z</i>. <i>medoensis</i> and <i>Z</i>. <i>sinensis</i> lack a strongly elongate and coiled flagellum, indicating that these two species may be more closely related to <i>Z</i>. <i>ceylonicus</i> Silverstri from Sri Lanka (Hwang 1974: 427) than to the southeastern Asian and central American species that share this structure (see ‘Comparative diagnosis’ of <i>Z</i>. <i>hainanensis</i> sp. n. above, and Mashimo et al. 2013: 512).</p>Published as part of <i>Yin, Zi-Wei, Li, Li-Zhen & Wu, Chao, 2015, New and little known species of Zorotypus Silvestri (Zoraptera: Zorotypidae) from China, pp. 557-566 in Zootaxa 4007 (4)</i> on page 565, DOI: 10.11646/zootaxa.4007.4.6, <a href="http://zenodo.org/record/240040">http://zenodo.org/record/240040</a>
Lyman break galaxies and the star formation rate of the Universe at z ~ 6
Get PDFWe determine the space density of UV-luminous starburst galaxies at z≈ 6 using deep HST ACS SDSS-i′ (F775W) and SDSS-z′ (F850LP) and VLT ISAAC J and Ks band imaging of the Chandra Deep Field South. We find eight galaxies and one star with (i′−z′) > 1.5 to a depth of z′AB= 25.6 (an 8σ detection in each of the 3 available ACS epochs). This corresponds to an unobscured star formation rate of ≈15 h−270 M⊙ yr−1 at z= 5.9, equivalent to L* for the Lyman-break population at z= 3–4 (ΩΛ= 0.7, ΩM= 0.3). We are sensitive to star-forming galaxies at 5.6 ≲z≲ 7.0 with an effective comoving volume of ≈1.8 × 105h−370 Mpc3 after accounting for incompleteness at the higher redshifts due to luminosity bias. This volume should encompass the primeval subgalactic-scale fragments of the progenitors of about a thousand L* galaxies at the current epoch. We determine a volume-averaged global star formation rate of (6.7 ± 2.7) × 10−4h70 M⊙ yr−1 Mpc−3 at z∼ 6 from rest-frame UV selected starbursts at the bright end of the luminosity function: this is a lower limit because of dust obscuration and galaxies below our sensitivity limit. This measurement shows that at z∼ 6 the star formation density at the bright end is a factor of ∼6 times less than that determined by Steidel et al. for a comparable sample of UV-selected galaxies at z= 3–4, and so extends our knowledge of the star formation history of the Universe to earlier times than previous work and into the epoch where reionization may have occurred
The Benefits of Being Economics Professor A (and not Z)
Get PDFAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering

Reynolds number dependence of the dimensionless dissipation rate in stationary magnetohydrodynamic turbulence
No full textResults on the Reynolds number dependence of the dimensionless total dissipation rate C_ε are presented, obtained from medium to high resolution direct numerical simulations (DNSs) of mechanically forced stationary homogeneous magnetohydrodynamic (MHD) turbulence in the absence of a mean magnetic field, showing that C_ε -> const with increasing Reynolds number. Furthermore, a model equation for the Reynolds number dependence of the dimensionless dissipation rate is derived from the real-space energy balance equation by asymptotic expansion in terms of Reynolds number of the second- and third-order correlation functions of the Elsässer fields z± = u ± b. At large Reynolds numbers we find that a model of the form C_ε = C_ε,∞ + C/R describes the data well, while at lower Reynolds numbers the model needs to be extended to second order in 1/R in order to obtain a good fit to the data, where R is a generalised Reynolds number with respect to the Elsässer field z-
Improvement of low-velocity impact and compression-after-impact performance by z-fibre pinning.
Get PDFZ-fibre® pinning is a new method of through-thickness reinforcement of laminated
composites. This paper presents an experimental test and theoretical analysis on
how and why these pins can improve the resistance to impact loading and post-
impact compression. Specimens were made of carbon/epoxy T300/914C with nominal
thicknesses of 2, 4, and 6 mm. For the specimens tested in this study, z-pinning
reduced impact damage area by 19–64% depending on the specimen thickness and
impact energy. Experimental results obtained also indicate that z-pins can
significantly increase the compression-after-impact (CAI) strength by about 45%.
In this paper all of these observations are discussed in the context of
theoretical and numerical models that have been developed previously to predict
the critical impact force and z-pinning performance in terms of the laminate in-
plane stiffness and mode I delamination fracture toughness with the z-fibre

Enhanced image retrieval using spatial information and ontologies
No full textNew approaches are essential to improve the inference of semantic relationships from low-level features for image annotation and retrieval. Current research on image annotation sometimes represents images in terms of regions and objects, but pays little attention to the spatial relationships between those regions or objects. Annotations are most frequently assigned at the global level, and even when assigned locally the extraction of relational descriptors is often neglected. To enrich the semantic description of the visual information, the use of spatial relationships offers one way to describe objects in an image more richly and often captures a relevant part of information in the image. In this thesis, new approaches for enhancing image annotation and retrieval by capturing spatial relationships between labelled objects in images are developed. Starting with an assumption of the availability of labelled objects, algorithms are developed for automatically extracting absolute object positional terms and relative terms describing the relative positions of objects in the image. Then, by using order of magnitude height information for objects in the domain of interest, relative distance of objects from the camera position in the real world are extracted, together with statements about nearness of objects to each other in the image and nearness in the real world. A knowledge-based representation is constructed using spatial and domain specific ontologies, and the system stores the asserted spatial statements about the images, which may then be used for image retrieval. The resulting Spatial Semantic Image System is evaluated using precision, recall and F-scores to test retrieval performance, and a small user trial is employed to compare the system’s spatial assertions with those made by users. The approach is shown to be capable of handling effectively a wide range of queries requiring spatial information and the assertions made by the system are shown to be broadly in line with human perceptions
Porównanie polsko-litewskiej Konstytucji z 3 maja 1791 r. z hiszpańską Konstytucją z 19 marca 1812 r.
Get PDFThe purpose of this article was to make a brief comparative analysis between the Spanish Constitution of 1812 and the Polish-Lithuanian Constitution of 1791. With this intention, the most characteristic features of each constitutional text were set out, and both the historical and social context prior to its promulgation and the circumstances that led to the drafting of both legal acts were analyzed. The similarities and contrasts of the political models established with both constitutions were observed, as well as the rights and freedoms recognized. Reference was also made to the founding fathers of the Constitutions and the ideological context that influenced them. Finally, the author mentioned the fate of both constitutions that were only in force for a short period of time. The article aimed to present these two legal acts that were a milestone in the constitutional and political history of each nation.Celem artykułu było przeprowadznie krótkiej analizy porównawczej hiszpańskiej Konstytucji z 1812 r. oraz polsko-litewskiej Konstytucji z 1791 r.

Uchwycono podobieństwa i różnice modeli politycznych oraz praw i wolności ustanowionych w obu konstytucjach. Odniesiono się też do ojców założycieli konstytucji i kontekstu ideologicznego, który na nich wpłynął. Ponadto autorka wspomina o losie obu Konstytucji, które obowiązywały jedynie przez krótki okres. Celem artykułu było przybliżenie tych dwóch aktów prawnych, stanowiących kamienie milowe w konstytucjonalnej i politycznej historii obu narodów
Self-archiving practice and the influence of publisher policies in the social sciences
No full textAuthors in different disciplines exhibit very different behaviours on the so-called ‘green’ road to open access, i.e. self-archiving. This study looks at the self-archiving behaviour of authors publishing in leading journals in six social science disciplines. It tests the hypothesis that authors are self-archiving according to the norms of their respective disciplines rather than following self-archiving policies of publishers, and that, as a result, they are self-archiving significant numbers of publisher PDF versions. It finds significant levels of
self-archiving, as well as significant self-archiving of
the publisher PDF version, in all the disciplines
investigated. Publishers’ self-archiving policies have
no influence on author self-archiving practice
