The sigma orientation for analytic circle-equivariant elliptic cohomology
, 2002 We construct a canonical Thom isomorphism in Grojnowski's equivariant elliptic cohomology, for virtual T-oriented T-equivariant spin bundles with vanishing Borel-equivariant second Chern class, which is natural under pull-back of vector bundles and ...

Modified Rodrigues Parameters: An Efficient Representation of Orientation in 3D Vision and Graphics
Journal of Mathematical Imaging and Vision, 2018 Modified Rodrigues parameters (MRPs) are triplets in $${\mathbb {R}}^3$$R3 bijectively and rationally mapped to quaternions through stereographic projection.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Remote SensingRotating mirror-based space cameras are susceptible to mirror misalignment due to the severe vibrations experienced during rocket launch and the harsh, variable conditions of the space environment, which can result in deviations of the camera’s line of ...

Fluids, 2019 The study is motivated by monitoring the space orientation of a hydrolic fracture used in oil production. Streaming potential arises due to the leakage of ionic fracking fluid under the rock elastic forces which make the fracture disclosure disappear ...

The heptagon-wheel cocycle in the Kontsevich graph complex [PDF]
, 2017 The real vector space of non-oriented graphs is known to carry a differential graded Lie algebra structure. Cocycles in the Kontsevich graph complex, expressed using formal sums of graphs on $n$ vertices and $2n-2$ edges, induce -- under the orientation ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Direct field oriented control scheme for space vector modulated AC/DC/AC converter fed induction motor [PDF]
Frontiers in Energy, 2012 This paper investigates a Luenberger flux observer with speed adaptation for a direct field oriented controlof an induction motor. An impoved method of speed estimation that operates on the principle of speed adaptative flux and current observer has been proposed.
