Oileus gasparilomisp. n. is described from nine specimens from the mountains of Quiché in Guatemala, from cloud forest at 1795 m elevation. This represents the second species of the genus for Guatemala, differing from the closely related Mexican species Oileus rimator (Truqui) in having a straight anterior clypeal border, the postocular sulcus divided by a keel and the pronotum almost straight ...
A new hovering goby or dartfish is described from material collected in Mexico, Costa Rica and Panama. It is the only species of the cosmopolitan genus Ptereleotris known from the eastern Pacific. It is distinguished from its Western Atlantic and Indo-Pacific congeners by its low fin-ray counts, prominent median keel on the ventral margin of the head, lanceolate caudal fin with dusky lower half...
Let $U$ be an affine log Calabi-Yau variety containing open algebraic torus. We show that the naive counts of rational curves in uniquely determine a commutative associative algebra equipped with compatible multilinear form. This proves variant Frobenius structure conjecture by Gross-Hacking-Keel mirror symmetry, and spectrum this is supposed to give hypothetical family. Although statement our ...
INTRODUCTION: Initial implant stability is crucial to cementless knee replacement success, however the optimal design remains elusive. Previous biomechanical studies have aimed at quantifying initial stability using simplified loading scenarios. The objective of this study was to use a physiological relevant methodology which incorporates torsion, shear and compression forces to evaluate tibial...
Cercariae capricornia I–VI, six new cercariae putatively identified as belonging to the Acanthocolpidae, are described and named from prosobranch gastropods of the family Nassariidae collected from the intertidal zone in the Capricornia region, Central Queensland, Australia. Four species are reported from Nassarius olivaceus and two from N. dorsatus. The cercariae have a unique and complex thre...
An attempt has been made to employ evolving Takagi-Sugeno algorithm (eTS) to built models assisting property valuation on the basis of actual data drawn from cadastral system, registry of sales transactions, and a cadastral map. Seven methods of feature selection were applied an evaluated. The eTS performance was compared to three algorithms implemented in KEEL, including model trees for regres...

We propose the name Bumba as a new name for Maraca, preoccupied by Maraca Hebard, 1926 (Orthoptera). We describe and illustrate Bumbalennoni, a new theraphosid species from Caxiuanã, Pará, Brazil. This species differs from the other species of the genus in the extremely reduced keel on male palpal organ and in the higher number of labial and maxillary cuspules. Females additionally differ in th...
We define syzygy points of projective schemes, and introduce a program of studying their GIT stability. Then we describe two cases where we have managed to make some progress in this program, that of polarized K3 surfaces of odd genus, and of genus six canonical curves. Applications of our results include effectivity statements for divisor classes on the moduli space of odd genus K3 surfaces, a...
Mori dream spaces were introduced by Y. Hu and S. Keel [9]; they are natural generalizations of toric varieties. We recall the definition. Let X be a Q-factorial and normal projective variety, such that Pic(X)⊗Z Q = N(X). Let D1, . . . , Dr be a collection of divisors that give a basis for Pic(X), and whose affine hull contains the pseudoeffective cone. The Cox ring of X is the multi-graded sec...
