Abrégé

Technologies are generally described herein generally relate to tunnel field-effect transistor (TFETs) structures with a gate-on-germanium source (GoGeS) on bulk silicon substrate for sub 0.5V (VDD) operations. In some examples, the GoGeS structure may include an increase in tunneling area and, thereby, a corresponding increases in the ON-state current ION. In order to achieve supersteep sub-threshold swing, both the lateral tunneling due to gate electric-field and the non-uniform tunneling at the gate-edge due to field-induced barrier lowering (FIBL) may be suppressed through selection of component dimension in the device structure. Example devices may be fabricated using CMOS fabrication technologies with the addition of selective etching in the process flow.

Abrégé

Exposure to a static magnetic field changes the fluorescence intensity of a wide range of fluorophores, including small molecules (e.g., tryptophan), complex organizations of fluorophores (e.g., proteins), quantum dots, nanoparticles, and other materials. Different materials may experience different changes in fluorescence emission upon exposure to a magnetic field— for instance, some or all of a material's fluorescence emission spectrum may increase in amplitude or shift in wavelength. Different materials may also experience different changes in relaxation time, which is the time constant associated with fluorescence decay. These magnetically induced differences fluorescence emission spectra and decay can be used to identify, classify, or sort materials noninvasively.

Abrégé

A technique for determining whether or not a fluorescent material exhibits a directionally dependent property, such as anisotropy or chirality, involves illuminating the particle at its excitation wavelength to stimulate fluorescent emission at both a full-frequency (fundamental) wavelength and a half-frequency wavelength. The ratio of the full-frequency signal strength to the half-frequency signal strength provides an indication of the sample's directionally dependent property. This half-frequency spectral analysis can be used to sort anisotropic particles suspended in fluid flowing through a flow cytometer. For instance, the present technique may be used to separate racemic mixtures of chiral enantiomers of cells, pharmaceutical compounds, and other samples.

Abrégé

The synthesis and evaluation of gastroprotective effect of different tryptamine derivatives. Tryptamine derivatives have been synthesized by formation of amide or ester with some known anti oxidant molecules. These derivatives show excellent antioxidant property in vitro. Among all the derivatives the compound SEGA (3a), that was prepared by the combination of serotonin with gallic acid shows the greater antioxidant property than the other synthesized compounds both in vivo and in vitro. SEGA(3a) shows the gastroprotective effect against NSAIDs (indomethacin or diclofenac)-induced gastropathy in dose dependent manner and also accelerates the healing from injury. It prevents the NSAIDs-induced mitochondrial oxidative stress in vivo. This derivative prevents NSAID-induced mitochondrial oxidative stress-mediated apoptosis in vivo by preventing the activation of caspase 9 and caspase-3 and restores NSAIDs-mediated collapse of mitochondroial transmembrane potential and dehydrogenase activity. SEGA (3a) plays an important role as an iron chelator as well as intra mitochondrial ROS scavenger. Thus, SEGA (3a) is a potent antioxidant antiapototic molecule, which efficiently prevents NSAID-induced gastropathy and stress or alcohol-mediated gastric damage.

Technologies are generally described for systems and methods for detecting chiral properties of materials and separating materials based on their chiral properties. A chiral vector is constructed from anisotropy properties of a polarization-dependent output signal from a sample. Different types of molecules from the sample can be differentiated based on a magnitude of the chiral vector. Chiral properties of the sample can be detected based on an angle of the chiral vector. The output signal can be a fluorescent emission from the sample and can be used to detect chiral properties of a substantially opaque sample.

Abrégé

Techniques generally disclosed herein relate to computation of a guard zone of a three-dimensional object. In some examples, guard zones may be computed by identifying intersection lines that couple adjacent planes of an object, and categorizing an external angle at an intersection line between adjacent planes as concave or convex. In some embodiments, for convex angles, a cylindrical surface can be determined that is located about an outside surface of the object and centered along the intersection line between the adjacent planes. In some embodiments, for concave angles, the external angle can be bisected with a bisection plane. A guard zone may be formed by one or more of (i) providing a guard zone plane parallel to the object that is a tangent to a given cylindrical surface, (ii) providing a guard zone plane parallel to the object that intersects a given bisection plane, and/or (iii) coupling adjacent guard zone planes.

Abrégé

Disclosed are methods and systems for identifying and sorting cells based on a near-infrared emission pattern of the cell in response to excitation at 630 ± nm. The NIR emission pattern can be used for monitoring and sorting of cells in a label-free manner, and thus provides a positive method for selecting cells, such as stem cells, for use in therapy.

Abrégé

A Link Layer (e.g., TCP/IP Layer 1, OSI Layer 2) routing protocol that routes frames from a sending node to a receiving node based upon service solicitation and availability is proposed. The routing protocol may reduce control messages across the layers, and may achieve greater energy efficiency by placing non-participating nodes into a sleep mode for durations of time while an ad hoc network is being utilized by participating nodes. The proposed scheme may also reduce network setup time by enabling routing as soon as a service and corresponding request is initiated.

Abrégé

The present invention discloses a process for detecting the presence or absence of human hemoglobin HbAO and/or HbE in a sample by way of nanoparticle - hemoglobin interaction. Clusters of copper nanoparticles (average cluster size 160nm) undergo a multi step transition on interaction with HbAO, the normal fraction of human hemoglobin. Longer interaction of HbAO with Cu nanoparticles leads to aggregation with the formation of micron sized structure, which immediately precipitates out of the solution. This nanoparticle and protein interaction helps to separate out specific proteins even if they have very close homology (like the discrimination of HbAO from HbC or HbE from Hb A2). The present invention has important applications in hemoglobinopathy in particular and proteomic applications in general.
