Jagadiya Dam, River Khari, Kutch District (also spelt as Kachchh) Gujarat, India. Etymology. The species is named for Kutch District, Gujarat, from where the specimens were collected. Remarks. Caridina kutchi sp. nov. is distinguished by long, slender rostrum that is distinctly longer than antennal scale, the unarmed dorsal margin interrupted by a single tooth distally; pointed tip of rostrum with fine setae on the dorsal margin; telson posterior margin narrow and triangular with a median projection bearing intermediate spines of equal length that are distinctly shorter than the laterals. Caridina kutchi sp. nov. is similar to Caridina simoni Bouvier, 1904 which was described from Sri Lanka and now reported from South India (Richard and Clark 2014) in the structure of rostrum with pointed tip and the distal unarmed rostral margin interrupted by a single tooth distally. However, C. kutchi sp. nov. distinctly differs from C. simoni in telson structure. C. kutchi sp. nov. could be distinguished from C. simoni in having rostrum that is distinctly longer than antennal scale (vs. equal to or slightly longer than antennal scale in C. simoni); unarmed dorsal rostral margin interrupted by a single tooth distally (vs. unarmed dorsal rostral margin interrupted by 0–4 teeth in C. simoni); posterior margin of telson narrow and triangular with a median projection (vs. posterior margin of telson broad and rounded without a median projection in C. simoni); telson posterior margin bearing 2–3pairs of sparsely plumose intermediate spines of equal length and distinctly shorter than laterals spine (vs. 3–4 pairs of sparsely plumose intermediate spines either equal in length and slightly shorter than the laterals or the median pair longer and equal to laterals in C. simoni); preanal carina armed with a spine (vs. preanal carina unarmed in C. simoni). Caridina kutchi sp. nov. differs from C. babaulti, which is now reported from Gujarat, in possessing rostrum that is distinctly longer than antennal scale (vs. rostrum equal to antennular peduncle or shorter reaching middle of 3 rd antennular peduncle segment in C. babaulti); 12–22 teeth proximally leaving 0.5–0.65 of dorsal margin unarmed distally which is interrupted by a single tooth at distal end (vs. 14–25teeth proximally leaving 0.1–0.23 of dorsal margin unarmed distally in C. babaulti); 1–3 post orbital teeth present (vs. 3–7 postorbital teeth present in C. babaulti); 9–15 teeth proximally leaving 0.1–0.2 of ventral margin unarmed distally (vs. 3–8 teeth proximally leaving 0.1–0.45 of ventral margin unarmed distally in C. babaulti); carpus of first pereiopod with anterior excavation (vs. carpus of first pereiopod with deep anterior excavation in C. babaulti); telson posterior margin narrow and triangular, with a median projection (vs. telson posterior margin broad and rounded, with or without median protrusion in C. babaulti); 2–3 pairs of sparsely plumose intermediate spines of equal length and distinctly shorter than laterals (vs. 2–4 pairs or 5 sparsely plumose intermediate spines of varying length; fractionally longer or shorter than the lateral spines in C. babaulti); 8–12 uropod diaeresis spinules (vs. 12–21 uropod diaeresis spinules in C. babaulti); preanal carina armed with a spine (vs. preanal carina unarmed in C. babaulti). Caridina kutchi sp. nov. is the first Caridna species to be described from Kutch district, Gujarat state, which is known for its complex geological set up.Published as part of Pandya, Pranav J. & Richard, Jasmine, 2019, Report of Caridina babaulti Bouvier, 1918 (Crustacea: Decapoda: Caridea: Atyidae) and description of a new species Caridina kutchi sp. nov. from Gujarat, India, pp. 470-482 in Zootaxa 4568 (3) on pages 477-480, DOI: 10.11646/zootaxa.4568.3.3, http://zenodo.org/record/260166
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
An integrated fuzzy logic system under Microsoft Azure using Simpful
No full textMobile applications in the area of human-centered applications are based on fuzzy logic have exhibited their effectiveness in managing intelligent environments, however the deployment of mobile fuzzy logic systems has been usually associated with dedicated hardware and software packages. Introducing openness for fuzzy logic systems offers exciting features such as system independence, simplicity, load balancing, and controlled resource allocation. On the other hand, while major cloud service providers support readymade commercial services for AI techniques such as for deep neural networks, there is no similar services for fuzzy logic systems. This study aims to develop a cloud-based fuzzy logic system under Microsoft Azure, employing Simpful as the cloud-side Python library and FML as data exchange standard. The developed cloud service is shown to effectively serve mobile phone applications for human monitoring purposes. Also in the present study, two types of fuzzy inference systems namely Mamdani and TSK have been utilized wherein both these systems have been compared on the basis of their processing time and accuracy of result. Results indicated that Mamdani fuzzy inference system outperformed TSK fuzzy inference system in terms of processing time by 0.456 seconds. Moreover, the detection accuracy of Mamdani system was found to be higher than that of TSK system by 6.82%
Galaxies Going Bananas: Inferring the 3D Geometry of High-Redshift Galaxies with JWST-CEERS
No full textThis repository provides all figures for the Astrophysical Journal article "Galaxies Going Bananas: Inferring the 3D Geometry of High-Redshift Galaxies with JWST-CEERS" by Viraj Pandya et al. We also include a machine readable version of Table 2.
Below we describe the four figure sets corresponding to Figures 7, 8, 13 and 23 in the paper as well as Table 2. This repository also includes all individual figures not comprising sets -- for a description of these, we refer the user to their corresponding captions in the paper.
Figure 7 shows corner plots from our constrained Bayesian model for 3D galaxy shapes in a single mass-redshift bin. The figure set here includes analogous corner plots for the other mass-redshift bins.
Figure 8 shows the fractional contribution of ellipsoids of different types (prolate, oblate, spheroidal) to the observed joint distribution of projected axis ratios and sizes. This figure also shows that we can use these fractional model contributions to assign 3D shape probabilities to individual observed galaxies. The figure set here includes analogous figures for other mass-redshift bins and for our model applied independently to the SE++ and Galfit data.
Figure 13 shows a histogram of 3D axis ratios (C/A vs B/A) computed as the average of 500 draws from our model posterior for every mass-redshift bin. The version in the paper is for our model applied to the SE++ data. The additional figure here is for our model applied to the Galfit data.
Figure 23 shows mock parameter recovery tests for Hamiltonian Monte Carlo applied to our Bayesian 3D galaxy shape model with different sample sizes. The version in the paper is for a mock population of ellipsoids dominated by prolate objects. The additional figures here are for additional mock populations dominated by either spheroids, oblate (axisymmetric) disks, or triaxial (oval) disks.
Table 2 summarizes the means and standard deviations of our Bayesian model as well as ellipsoid class fractions for every mass-redshift bin. The results from both of our models based on Galfit and SE++ have been combined into this single table. This is a machine readable table that can easily be read in with, e.g., the Python astropy.table module
Developing a cloud-based service-oriented architecture for fuzzy logic systems
No full textFuzzy logic systems are customarily related to specific hardware or software systems. Nevertheless, it has been observed that distributed and cloud-based architectures of various intelligent systems are pouring intensifying attention. While the distributed architectures can potentially add values in developing fuzzy systems, a lack of standard methods and practices may limit their public use. This study aims to provide a standard solution for developing cloud-based service-oriented architectures for fuzzy logic systems, based on extending IEEE-1855 (2016) in the defining system and exchanging data. Experiments were performed employing simulation concerning collection, processing and monitoring of data in a distributed manner over the web. A real-time human activity recognition simulated scenario is also demonstrated through a cloud-based fuzzy system
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
