ZrTe5 and HfTe5 have attracted increasingly attention recently since the theoretical prediction of being topological insulators (TIs). However, subsequent works show many contradictions about their topolog-ical nature. Three possible phases, i.e. strong TI, weak TI, and Dirac semi-metal, have been observed in different experiments until now. Essentially whether ZrTe5 or HfTe5 has a band gap or ...

We study data driven Web services provided by Web sites interacting with users or applications The Web site can access an underlying database as well as state information updated as the interaction pro gresses and receives user input The structure and contents of Web pages as well as the actions to be taken are determined dynamically by querying the underlying database as well as the state and ...

Downlo roRNAs (miRNA), a class of natural RNA-interfering agents, have recently been identified as attractive s for therapeutic intervention. The rationale for developing miRNA therapeutics is based on the premise berrantly expressed miRNAs play key roles in the development of human disease, and that correcting miRNA deficiencies by either antagonizing or restoring miRNA function may provide a ...

The main goal of this work is to formalize the use of fuzzy systems represented by Takagi Sugeno form so that the use of membership functions is well understood when designing the rules It also aimed to apply these ideas later when designing fuzzy controllers where dynamic models are used First static mod els are introduced Second some useful de nitions are presented Third the main prop erties ...

We show that the complex PT -symmetric periodic potential V (x) = −(iξ sin 2x+ N)2, where ξ is real and N is a positive integer, is quasi-exactly solvable. For odd values of N ≥ 3, it may lead to exceptional points depending upon the strength of the coupling parameter ξ. The corresponding Schrödinger equation is also shown to go over to the Mathieu equation asymptotically. The limiting value of...

We study the problem of multimodal dimensionality reduc6 6 tion assuming that data samples can be missing at training time, and 7 7 not all data modalities may be present at application time. Maximum 8 8 covariance analysis, as a generalization of PCA, has many desirable prop9 9 erties, but its application to practical problems is limited by its need for 10 10 perfectly paired data. We overcome...
