We study the global nonexistence of the solutions of the nonlinear qLaplacian wave equation utt −∆qu + (−∆)ut = |u|p−2u, where 0 < α ≤ 1, 2 ≤ q < p. We obtain that the solution blows up in finite time if the initial energy is negative. Meanwhile, we also get the solution blows up in finite time with suitable positive initial energy under some conditions.

In this paper, we develop a new feature extraction method, called discriminate multidimensional mapping (DMM), which is especially effective for small sample database. The algorithm takes advantages of MDS and LDA, meanwhile avoids their disadvantages. We give theoretical analysis of this algorithm, and demonstrate with examples that DMM is effective in practical use.

Methods 20 SRS cases diagnosed in Beijing Children’s Hospital from 2006 to 2011 were studied retrospectively for clinical manifestations, physical signs, laboratory examinations and respond of GH treatment. We compared with 3 different diagnostic criteria and used the methylationspecific multiplex ligation dependent probe amplification (MS-MLPA) method to detect the chromosome 11p15 imprinting ...

Recently an article published in Molecular Cell reveals the mechanism of a nuclear N-methyladenosine (mA) reader, the YTH domain-containing protein 1 (YTHDC1), in regulating pre-mRNA splicing [1]. Meanwhile, two additional articles published in Nature and Nature Chemical Biology report the first transcriptome-wide maps of N-methyladenosine (mA) at high resolution, suggesting a functional role f...

Key core technologies of IOT (internet of things) have to be addressed to achieve rapid development. This paper focused on studying RFID, wireless sensor network (WSN) and TCCP which were integrated to address the IOT application problems. Meanwhile, an IOT architectural model was established and the IOT applications in real-time medical monitoring, intelligent transportation system (ITS), inte...

We present a case of posterior ventricular septal rupture associated to left ventricular aneurysm manged, during peri-operative period, by transthoracic and transesophageal echocardiography. Three-dimensional transesophageal echocardiography findings add adjunctive and more accurate information regarding morphological details of the ventricular septal rupture rather than two-dimensional echocar...

We study a kind of vector singular perturbed delay-differential equations. By using the methods of boundary function and fractional steps, we construct the formula of asymptotic expansion and confirm the interior layer at t = σ. Meanwhile, on the basis of functional analysis skill, the existence of the smooth solution and the uniform validity of the asymptotic expansion are proved.

Donors, governments, microfinance networks, and foundations have promoted housing microfinance (“HMF”) for a decade. Considerable operational experience has accrued on this practice over this time. Meanwhile, many emerging economies have grown rapidly, which has changed housing markets and the context for HMF. The moment, then, is auspicious for a re-examination of housing microfinance and its ...

Agricultural knowledge resources are distributive, heterogeneous and polymorphic. Knowledge representation, organization and integrated application is a complicated and challenging problem in the environment of distributed computing. This paper reviews present condition of domestic and foreign researches on agricultural ontology, and introduces the ontology theory and agricultural knowledge rep...

Lysinibacillus sp. ZYM-1, a Gram-positive strain isolated from marine sediments, reduces selenite and tellurite efficiently. Meanwhile, it also exhibits high resistance to Zn2+ and Mn2+. Here, we report the draft genome sequence of strain ZYM-1, which contains genes related to selenite and tellurite reduction and also metal resistance.
