‎In this paper‎, ‎we study translation invariant surfaces in the‎ ‎3-dimensional Heisenberg group $rm Nil_3$‎. ‎In particular‎, ‎we‎ ‎completely classify translation invariant surfaces in $rm Nil_3$‎ ‎whose position vector $x$ satisfies the equation $Delta x = Ax$‎, ‎where $Delta$ is the Laplacian operator of the surface and $A$‎ ‎is a $3 times 3$-real matrix‎.

Connective tissue growth factor (CCN2), a member of the CCN family of proteins, is a cysteine-rich matricellular protein. Connective tissue growth factor is not normally expressed in dermal fibroblasts unless induced. The most potent inducer of connective tissue growth factor thus far identified is transforming growth factor beta. Connective tissue growth factor, however, is constitutively over...

water use efficiency (wue, the ratio of total dry matter to water use) became a breeding target only when it was found that carbon stable isotopes were inversely related to wue. the current study conducted under well-watered and drought conditions in the field over two years at broom’s barn research station, uk, was undertaken to investigate the extent of genotypic differences for water use, yi...

in this paper we introduce the notions of g∗l-module and g∗l-module whichare two proper generalizations of δ-lifting modules. we give some characteriza tions and properties of these modules. we show that a g∗l-module decomposesinto a semisimple submodule m1 and a submodule m2 of m such that every non-zero submodule of m2 contains a non-zero δ-cosingular submodule.

In vivo cultivated connective tissue is rich in lipids. That obtained from man and chicken has larger concentrations of neutral fat and cholesterol than connective tissue of other species. Connective tissue synthesizes cholesterol and possesses a striking avidity for retention of either endogenous or exogenous cholesterol. The fibrous portion of sponge-connective tissue of the rabbit incorporat...

Abstract Sahlqvist theory is extended to the fragments of intuitionistic propositional calculus that include conjunction connective. This allows us introduce a character amenable arbitrary protoalgebraic deductive systems. As an application, we obtain theorem for implication connective and extensions linear logic.

The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...

triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...
