The taxonomic status of Phlebotomus breviductus Barretto, 1950 was evaluated based on the morphological and morphometric analysis of the male holotype described from Fazenda Jerusalém, located in the municipality of Alegre, Espírito Santo state, Brazil. After measuring, drawing and photographing the holotype, we concluded that the head and wing of this specimen belong to Trichopygomyia sp., but...

A successful renormalization-group (RG) approach may provide signinicant insights of a system exhibiting power-law dependencies. In 1994, a RG scheme [1] was proposed for sandpile models which exhibit power-law behavior and function as the models of self-organized criticality [2]. One momentous result of such a RG approach is that BakTang-Wisenfeld (BTW) [2] sandpile posepossing a deterministic...

Methods: The Optic Nerve (ON) coil was constructed using two fiberglass formers that fit together to surround the entire head. The anterior former supports 26 overlapping coil elements in a mask arrangement as shown in Fig. 1. The posterior former supports the neck and head and houses two additional overlapped coil elements, totaling to 28 elements. In this design, the two formers can slide ove...

OBJECTIVE To quantify pediatric injuries and deaths that result from toppled television sets. DESIGN Retrospective analysis of incident files compiled by the US Consumer Product Safety Commission (CPSC) data systems and The Children's Hospital of Alabama (TCHA) inpatient medical records. SETTING United States, January 1990-June 1997. TCHA, May 1995-October 1997. MAIN OUTCOME MEASURES Morb...

Recall that an excedance of a permutation $\pi$ is any position $i$ such $\pi_i > i$. Inspired by the work Hopkins, McConville and Propp (Elec. J. Comb., 2017) on sorting using toppling, we say toppleable if it gets sorted certain sequence toppling moves. One our main results number permutations $n$ letters same as those for which excedances happen exactly at $\{1,\dots, \lfloor (n-1)/2 \rfl...

Toppling is a common deformation and failure phenomenon in the reservoir bank slopes of hydropower projects. This paper studies genesis evolution different toppling bodies during water impoundment at Miaowei Hydropower Station Reservoir on Lancang River southwest China. properties were determined second characteristics analyzed stages. Different degrees primarily affected by transverse bending ...

The chronology of the geologic timescale’s stratigraphic units has been defi ned by a variety of methods. Over the decades many have waxed and waned in popularity, but at present the most important ones are: (1) radiometric dating, (2) astronomical “tuning,” (3) magnetostratigraphy, and (4) biostratigraphy. Each of these methods assumes deep time and uniformitarianism rather than demonstrating ...

BACKGROUND Behaviors involved in courtship and male-male combat have been recorded in a taxonomically broad sample (76 species in five families) of snakes in the clade Boidae + Colubroidea, but before now no one has attempted to find phylogenetic patterns in such behaviors. Here, we present a study of phylogenetic patterns in such behaviors in snakes. METHODOLOGY/PRINCIPAL FINDINGS From the l...

Were it not for the antiphospholipid antibody syndrome, the United States might now have a National Health Service. That’s my conclusion from finding direct links between the most prominent victim of the syndrome—Queen Anne—and current debates over Scotland’s imminent secession from England. This September, Scots will hold a plebiscite on whether to dissolve a partnership that has lasted since ...

In this article, a novel yet simple step climbing robot is proposed and comprised of two front wheels, rear-wheel an actuator to vary the center distance between rear wheels. When climbs stair, huge variance in inclination angle may result its toppling. Hence, mechanism compensate for change angle. An inertial measuring unit (IMU) used sense which then fed microcontroller order actuate connecti...
