We study N=1 supersymmetric four-dimensional solutions of massive Type IIA supergravity with intersecting D6-branes in the presence NS-NS three-form fluxes. We derive N=1 supersymmetry conditions for the D6-brane and flux configurations in an internal manifold X6 and derive the intrinsic torsion (or SU(3)-structure) related to the fluxes. In the absence of fluxes, N=1 supersymmetry implies that...

In this paper, we proposed a systematic approach for automatically detecting and elimination redundant Eflags to optimize intermediate language (IL). We analyzed a broad spectrum of different IL and found that a number of IL expose all side effects explicitly by default and that not all the Eflags are relevant with subsequent analysis. Therefore, we proposed a unified approach, invertible analy...

A biologically inspired thermoresponsive polymer has been developed that mechanically induces tooth differentiation in vitro and in vivo by promoting mesenchymal cell compaction as seen in each pore of the scaffold. This normally occurs during the physiological mesenchymal condensation response that triggers tooth formation in the embryo.

Banana is the most widely cultivated fruit crop in Kerala. Nendran, a dual purpose cultivar grown for consumption as vegetable unripe stage and also fruit, upon ripening. An experiment was conducted during 2019-20 to extend shelf life of this through shrink wrapping, followed by storage under ambient cool chamber conditions, after sanitizing with chlorine (100 ppm) treatment alum (1 %) subseque...

Abstract Pineapple is widely grown in tropical countries, and the fruits are well-known for their unique flavor. The ideal stage of maturity, optimum storage temperature, congenial relative humidity, adequate type packaging critical factors that determine shelf life quality pineapple fruits. Therefore, this investigation was carried out to effect maturity shrink-wrap packaging, along with ambie...

Silica (SiO2) micro- and nanostructures fabricated with pre-stressed thermoplastic shrink wrap film have been shown to yield far-field fluorescence signal enhancements over their planar or wrinkled counterparts. The SiO2 structures have previously been used for improved detection of fluorescently labelled proteins and DNA. In this work, we probe the mechanism responsible for the dramatic increa...

We describe a manufacturable and scalable method for fabrication of multiscale wrinkled silica (SiO2) structures on shrink-wrap film to enhance fluorescence signals in DNA fluorescence microarrays. We are able to enhance the fluorescence signal of hybridized DNA by more than 120 fold relative to a planar glass slide. Notably, our substrate has improved detection sensitivity (280 pM) relative to...

The Unified Extensible Firmware Interface (UEFI) provides a consistent set of interfaces designed to support the booting of shrink-wrap operating systems, loading of drivers that replace legacy PC/AT option ROM’s, and support operating-system absent diagnostics and applications. In addition to this, UEFI capabilities are exported by C-callable interfaces, thus allowing for UEFI platforms to spa...

Structurally modified superhydrophobic surfaces have become particularly desirable as stable antibacterial surfaces. Because their self-cleaning and water resistant properties prohibit bacteria growth, structurally modified superhydrophobic surfaces obviate bacterial resistance common with chemical agents, and therefore a robust and stable means to prevent bacteria growth is possible. In this s...

We conjecture a topology changing transition in M-theory on a non-compact asymptotically conical Spin(7) manifold, where a 5-sphere collapses and a CP bolt grows. We argue that the transition may be understood as the condensation of M5-branes wrapping S5. Upon reduction to ten dimensions, it has a physical interpretation as a transition of D6-branes lying on calibrated submanifolds of flat spac...
