A revision of the subgenus Dudaica Strand of the genus Drosophila Fallén, with descriptions of six new species (Diptera, Drosophilidae)

The subgenus Dudaica Strand of the genus Drosophila Fallén has been known to comprise only two species: Drosophila (Dudaica) senilis Duda, 1926 (recorded from Indonesia, Philippines, Vietnam, Bhutan, and India) and D. malayana (Takada, 1976) (recorded from Malaysia). In the present study, this subgenus is revised, with D. malayana redescribed and six new species discovered and...

Creep resistance of as-cast Mg-5Al-5Ca-2Sn alloy

In the present study, creep properties of as-cast Mg-5Al-5Ca-2Sn (AXT552) alloy were investigated by means of a GWT304 creep testing machine at temperatures of 175 °C and 200 °C in the stress range of 35-90 MPa. Results show that creep rates increase with applied stress at an identical temperature. Creep strain at 100 hours is 0.0518% and 0.083% at creep conditions of 175°C/75MPa...

Dependence of Initial Value on Pattern Formation for a Logistic Coupled Map Lattice

The logistic coupled map lattices (LCML) have been widely investigated as well as their pattern dynamics. The patterns formation may depend on not only fluctuations of system parameters, but variation of the initial conditions. However, the mathematical discussion is quite few for the effect of initial values so far. The present paper is concerned with the pattern formation for a...

New fixed point theorems on order intervals and their applications

In this paper, we prove the existence of fixed points for nonlinear and semilinear operators on order intervals. The abstract results unified some methods in studying the existence of positive solutions for boundary and initial value problems of nonlinear difference and differential equations. Applications are shown by examples.

Existence of time homoclinic solutions for a class of discrete wave equations

In this paper, a class of nonperiodic discrete wave equations with Dirichlet boundary conditions are obtained by using the center-difference method. It is a strongly indefinite discrete Hamiltonian system. By using a variant and generalized weak linking theorem, the existence of the nontrivial time homoclinic solutions for the system will be obtained. The obtained main results...

Relevant Applications of Tools in UG NX CAM Module

In this paper, the methods to establish the custom magazine have been proposed while the UG NX CAM module is employed to conduct the CNC milling programming. At the same time, how to set the parameters of the cutting tool has been also analyzed; in the creation of tools, the use of shank and holder as well as the use of handle check functions in NC machining has been introduced...

Existence of Positive Solutions for a Class of Nonlinear Algebraic Systems

Based on Guo-Krasnoselskii’s fixed point theorem, the existence of positive solutions for a class of nonlinear algebraic systems of the form is studied firstly, where is a positive square matrix, , and , where, is not required to be satisfied sublinear or superlinear at zero point and infinite point. In addition, a new cone is constructed in . Secondly, the obtained results can...

Existence of time periodic solutions for a class of non-resonant discrete wave equations

In this paper, a class of discrete wave equations with Dirichlet boundary conditions are obtained by using the center-difference method. For any positive integers m and T, when the existence of time mT-periodic solutions is considered, a strongly indefinite discrete system needs to be established. By using a variant generalized weak linking theorem, a non-resonant superlinear (or...

Coordination Control Strategy for Compound Fault of MMC-HVDC

Single-line to ground fault of DC side and sub-module fault are typical faults of MMC-HVDC. When each of the above faults occurs, the system will give a signal for circuit-breaker releasing, this will result in interruption of power delivery, the stability of the system is greatly reduced. When these two faults occur simultaneously, research on control strategy for compound fault...

Existence and Uniqueness of Positive Solitons for a Second-Order Difference Equation

A discrete logistic steady-state equation with both positive and negative birth rate of population will be considered. By using sub- and upper-solution method, the existence of bounded positive solutions and the existence and uniqueness of positive solitons will be established. To this end, the Dirichlet eigenvalue problem with positive and negative coefficients is considered...

Culturable endophytic bacteria associated with medicinal plant Ferula songorica: molecular phylogeny, distribution and screening for industrially important traits

Xinjiang, a region of high salinity and drought, is a host to many arid and semi-arid plants. Many of these plants including Ferula spp. have indigenous pharmaceutical histories. As many of the medicinal properties of plants are in tandem with the associated microorganisms residing within the plant tissues, it is advisable to explore the endophytic potential of such plants. In...

Electroacupuncture Exerts Neuroprotection through Caveolin-1 Mediated Molecular Pathway in Intracerebral Hemorrhage of Rats

Spontaneous intracerebral hemorrhage (ICH) is one of the most devastating types of stroke. Here, we aim to demonstrate that electroacupuncture on Baihui (GV20) exerts neuroprotection for acute ICH possibly via the caveolin-1/matrix metalloproteinase/blood-brain barrier permeability pathway. The model of ICH was established by using collagenase VII. Rats were randomly divided into...
