Abstract:

The karotypes of six species of New Caledonian gekkos from the genera Rhacodactylus and Bavayia are described. The chromosomes of R. auriculatus, R. sarasinorum and B. sauvagei share a highly derived biarmed 2n=38 karyomorph, which is common to species from both New Zealand and Australia and is believed to be a relic from a previous Gondwanaland distribution. In contrast, R. leachianus, B. crassicollis and B. montana have karyotypes further modified from this karyomorph by a series of presumed pericentric inversions. This chromosomal repatterning appears to have been associated with the specia

Abstract:

This paper introduces GEKKO as an optimization suite for Python. GEKKO specializes in dynamic optimization problems for mixed-integer, nonlinear, and differential algebraic equations (DAE) problems. By blending the approaches of typical algebraic modeling languages (AML) and optimal control packages, GEKKO greatly facilitates the development and application of tools such as nonlinear model predicative control (NMPC), real-time optimization (RTO), moving horizon estimation (MHE), and dynamic simulation. GEKKO is an object-oriented Python library that offers model construction, analysis tools, a

Abstract:

Kluge (1967, 1983) proposed that the four subfamilies within the Gekkonidae were monophyletic assemblages, but that the Gekkoninae could be divided into two tribes on the basis of hyoid apparatus structure. Whilst agreeing that four subfamilies were present in the Gekkonidae, Moffatt (1973) argued that those groups of non-Eublepharine gekkos which remained after the differentiation of the Diplo- dactylinae and Sphaerodactylinae, and which had not become sufficiently distinct to be classified into separate subfamilies, had been lumped together as the Gekkoninae.

Abstract:

A chromosomal analysis of 47 species of diplodactyline gekkos indicates that these are a monophyletic assemblage derived from a 2n = 38 acrocentric ancestral karyotype. Four major clades are present, the first possessing the ancestral karyotype. The remainder are defined by the possession of a series of shared derived chromosomal rearrangements, or by the type of chromosome change. The first of these derived clades includes the subgenus Strophurus, which has five fixed, presumed pericentric inversion differences. The second includes members of the D. vittatus species group.

Abstract:

Geckos (Gekkota), the species-rich clade of reptiles with more than 2200 currently recognized species, demonstrate a remarkable variability in diploid chromosome numbers (2n = 16–48) and mode of sex determination.

Here, we applied both conventional (karyotype reconstruction and C-banding) and molecular (fluorescence in situ hybridization with probes for rDNA loci and telomeric repeats) cytogenetic analyses in seven species of geckos, namely Blaesodactylus boivini, Chondrodactylus laevigatus, Gekko ba

Abstract:

Gekko geckos are capable to crawl on the steep even on upside-down surfaces. Such movement, especially at great altitude, puts them at high risks of incidentally dropping down and inevitable body or head impactions, though they may trigger air-righting reaction (ARR) to attenuate the landing shocks. However, the air-righting ability (ARA) in Gekko geckos is not fully developed. The implementation of ARR in some geckos is quite slow; and for those without tails, the ARR is even unobservable. Since ARA is compromised in Gekko geckos, there must be some other mechanisms responsible for protecting

Abstract:

A new species of the genus Gekko Laurenti, 1768 is described from Phu Yen Province, southern Vietnam based on morphological and molecular evidence. Gekko phuyenensis sp. nov. differs from other congeners by its moderate size, with a snout-vent length of 90.2–92.8 mm; nares in contact with rostral; internasal 1; interorbitals 35 or 36; ventrals 30–32; dorsal tubercle rows 9 or 10; precloacal pores 12 or 13 in males and precloacal pits 13 in female; subdigital lamellae under first finger 18–21, fourth finger 19 or 20, first toe 18–20, and fourth toe 21–23; subcaudals median enlarged; no webbing

Abstract:

We report a new record in Bangladesh of the Smooth-backed Gliding Gecko Gekko lionotum Annandale, 1905, recorded from a biodiversity hotspot area at Bandarban located at the southeastern side of the country. A freshly dead specimen was collected and donated to the Padma Bridge Museum for further identification and display. We confirmed identification by comparing morphometric and meristic characteristics with literature records. Gekko lionotum is distributed in Myanmar and northeast India, but was not recorded previously from Bangladesh. The camouflaging color pattern and cryptic lifestyle of

Abstract An integrative taxonomic analysis of Sundaic populations of Gekko smithii from the Thai-Malaya Peninsula, Sumatra, and Borneo recovered four deeply divergent mitochondrial lineages that are separated by major geographic barriers (mountains and seaways). Furthermore, they bear a number of concordant statistically significant differences in meristic and morphometric features, morphospatial separation in multivariate space, and discrete differences in color pattern.

Abstract:

Sustainable manufacturing aspects are environmental, economic, and social. These aspects can be applied to an optimization model in the machining process. An optimization model is needed to determine the optimum cutting parameters. This research develops a multi-objective optimization model that can optimize cutting parameters on a multi-pass turning. Decision variables are cutting parameters multi-pass turning. This research has three objective functions for minimizing energy, carbon emissions, and costs. Three functions are searched for optimal values using the GEKKO. A numerical example is

Abstract:

Gekko is an optimization suite in Python that solves optimization problems involving mixed-integer, nonlinear, and differential equations. The purpose of this study is to integrate common Machine Learning (ML) algorithms such as Gaussian Process Regression (GPR), support vector regression (SVR), and artificial neural network (ANN) models into Gekko to solve data based optimization problems. Uncertainty quantification (UQ) is used alongside ML for better decision making. These methods include ensemble methods, model-specific methods, conformal predictions, and the delta method.
