Cone in Cone Concretions of the Stanley Group in southeastern Oklahoma
<p>Cone in cone concretions found in the Stanley Group of Southeastern Oklahoma have a variety of external and internal attributes which allow diagenetic and theoretical models of formation to be hypothesized. Stanley Group carbonate cone in cone concretions are initially formed in sulfur reducing …

Geometry of cone-beam reconstruction
… tool we use to unify all existing analytical cone-beam reconstruction methods. These reconstructions are based on formulae derived by Tuy [Tuy, 1983], Smith [Smith, 1985] and Grangeat [Grangeat, 1991] which explicitly link the cone-beam data to some intermediate functions in the Radon …

Singularities of the Perfect Cone Compactification
… taken into consideration consists of the perfect cone (also known as first Voroni) compactification of arithmetic quotients of type IV domains. These are of importance in the context of algebraic geometry because they are used to construct moduli spaces of polarised K3 surfaces and are strongly …

Cone penetration testing in polar snow
Innovative Cone Penetration Testing (CPT) using adapted commercial CPT equipment was conducted in Antarctica in early 2010 in an attempt to assess the strength of polar snow; additionally, application of CPT data was considered, particularly in estimating surface bearing capacity. Almost 100 CPT …

Studies on the cone pigment, iodopsin
… have been found against iodopsin and other cone pigments in chicken retina: (1) specifically against iodopsin (cell line of 7D3); (2) against iodopsin and another cone pigment (cell lines of 2D4, 4G2, and 5E3); and (3) against iodopsin and other three cone pigments (cell line of 2C3). One …

Sparse Fourier restriction for the cone
… new weighted Fourier extension estimate for the cone and its connection with the Mizohata–Takeuchi conjecture. The main result Theorem 3.1 builds on techniques from geometry originally explored by Tom Wolff in this context. The proof uses circular maximal function estimates first proved by Wolff …

Comparing Differentiated Rod And Cone Transcriptomes Reveals Rax As A Controller Of A Defined Cone Gene Regulatory Program
<b>Purpose</b><br></br>Rods and cones convert light stimuli into signaling information for brain- mediated visual perception. Specific gene mutations primarily affecting both photoreceptor (PRs) types lead to retinal dystrophies, including rod-cone (retinitis pigmentosa) and cone-rod degeneration. …

Characterisation and modelling of loudspeaker cone resonance
Loudspeaker cone resonance (“cone break-up”) is a fundamental cause of ripple in the electrical impedance and sound pressure responses of electrodynamic loudspeakers. In this thesis, the dependence of the characteristics of loudspeaker cone resonances on the material properties and thickness …

K-stability of Log Fano Cone Singularities
… thesis, we define the 𝛿-invariant for log Fano cone singularities, and show that the necessary and sufficient condition for K-semistability is 𝛿 ≥ 1. This generalizes the result of C. Li and K. Fujita. We also prove that on any log Fano cone singularity of dimension 𝑛 whose 𝛿-invariant is less …

Cone Beam Optical Computed Tomography-Based Gel Dosimetry
… accessible, fast optical readout tools such as cone beam optical computed tomography (CT) in combination with stable and reliable low-toxicity gel dosimeters is one key step in this process. In this thesis, the performance capabilities and limitations of the two main classes of cone beam optical …

Mechanisms of emplacement of cone sheets, Ardnamurchan, Argyll
Thin (1m), centrally inclined (cone) sheets of basic rock are a unique but common feature of the intrusive complexes within the Thulean Igneous Province. A field, structural, statistical and petrographic analysis of these sheets belonging to the Ardnamurchan Central Intrusive Complex has been made …

Dynamic Cone-beam Reconstruction for Perfusion Computed Tomography
Perfusion CT (Computed Tomography) is a dynamic imaging technique whose aim is to assess the blood supply to tissue. The limited field of view of current CT detectors restricts its use to perfusion studies of a small volume. The introduction of large area detectors in CT, however, will allow …

Studies on the Gecko P521 Cone-Type Pigment
In summary, mutational analysis and molecular approaches were used to identify components of the plant disease resistance pathway. The availability of the dnd mutants may facilitate further study of the control of HR cell death, gene-for-gene resistance, and broad spectrum disease resistance in …

Color vision: Studies on gecko cone visual pigment
Cone visual pigments are responsible for color vision. Although a large amount is known about rod pigments, relatively little is known about cone pigments. This thesis describes the identification and characterization of the photointermediates of gecko cone visual pigment P521: batho (ca. 570 nm), …
