Joint Quantile Disease Mapping for Areal Data

Alahmadi, Hanan H. 16 November 2021 (has links)
The statistical analysis based on the quantile method is more comprehensive, flexible, and not sensitive against outliers compared to the mean methods. The study of the joint disease mapping has usually focused on the mean regression. This means they study the correlation or the dependence between the means of the diseases by using standard regression. However, sometimes one disease limits the occurrence of another disease. In this case, the dependence between the two diseases will not be in the means but in the different quantiles; thus, the analyzes will consider a joint disease mapping of high quantile for one disease with low quantile of the other disease. In the proposed joint quantile model, the key idea is to link the diseases with different quantiles and estimate their dependence instead of connecting their means. The various components of this formulation are modeled by using the latent Gaussian model, and the parameters were estimated via R-INLA. Finally, we illustrate the model by analyzing the malaria and G6PD deficiency incidences in 21 African countries.

Geology and hydrothermal alteration, Glass Buttes, Southeast Oregon

Berri, Dulcy Annette 01 January 1982 (has links)
The Glass Buttes volcanic complex consists of many domes and individual vents that erupted both rhyolitic and basaltic lavas during the late Miocene to early Pliocene. The east half of the complex, in the vicinity of Little Glass Butte, contains interfingering, finely flow-banded rhyolite and black obsidian flows. The youngest unit, an obsidian, has been dated at 4.9 m.y. East of Little Glass Butte lie two northwest-trending ridges, Antelope and Cascade Ridges, composed of two or more overlapping exogenous domes that formed along northwest-trending faults.

Mechanical durability of hydrophobic surfaces fabricated by injection moulding of laser-induced textures

Romano, J.-M., Gülçür, Mert,, Garcia-Giron, A., Martinez-Solanas, E., Whiteside, Benjamin R., Dimov, S.S. 22 January 2019 (has links)
Yes / The paper reports an investigation on the mechanical durability of textured thermoplastic surfaces together with their respective wetting properties. A range of laser-induced topographies with different aspect ratios from micro to nanoscale were fabricated on tool steel inserts using an ultrashort pulsed near infrared laser. Then, through micro-injection moulding the topographies were replicated onto polypropylene surfaces and their durability was studied systematically. In particular, the evolution of topographies on textured thermoplastic surfaces together with their wetting properties were investigated after undergoing a controlled mechanical abrasion, i.e. reciprocating dry and wet cleaning cycles. The obtained empirical data was used both to study the effects of cleaning cycles and also to identify cleaning procedures with a minimal impact on textured thermoplastic surfaces and their respective wetting properties. In addition, the use of 3D areal parameters that are standardised and could be obtained readily with any state-of-the-art surface characterisation system are discussed for monitoring the surfaces' functional response. / European Commission H2020 ITN programme “European ESRs Network on Short Pulsed Laser Micro/Nanostructuring of Surfaces for Improved Functional Applications” (Laser4Fun) under the Marie Skłodowska-Curie grant agreement No. 675063 (www.laser4fun.eu) and the UKIERI DST programme “Surface functionalisation for food, packaging, and healthcare applications”.

Predictive Model Fusion: A Modular Approach to Big, Unstructured Data

Hoegh, Andrew B. 05 May 2016 (has links)
Data sets of increasing size and complexity require new approaches for prediction as the sheer volume of data from disparate sources inhibits joint processing and modeling. Rather modular segmentation is required, in which a set of models process (potentially overlapping) partitions of the data to independently construct predictions. This framework enables individuals models to be tailored for specific selective superiorities without concern for existing models, which provides utility in cases of segmented expertise. However, a method for fusing predictions from the collection of models is required as models may be correlated. This work details optimal principles for fusing binary predictions from a collection of models to issue a joint prediction. An efficient algorithm is introduced and compared with off the shelf methods for binary prediction. This framework is then implemented in an applied setting to predict instances of civil unrest in Central and South America. Finally, model fusion principles of a spatiotemporal nature are developed to predict civil unrest. A novel multiscale modeling is used for efficient, scalable computation for combining a set of spatiotemporal predictions. / Ph. D.

A geological Reconnaissance of the San Pedro del Gallo Area, Durango, Mexico

Alor, Jerjes Pantoja January 1963 (has links)
The San Pedro del Gallo area 1.8 in the north-central part of Mexico, between 25°30' and 26°00' N latitude, and 104°00' and 104°20' W longitude. It covers approximately 1,900 square kilometers at the western edge of the Sierra Madre Oriental. The oldest rocks exposed in the area belong to the Villa Juarez Formation of possible Late Triassic age. These rocks, of continental origin, comprise siltstone, sandstone, conglomerate, tuff, and intercalated lavas of characteristic red color. Jurassic and Cretaceous rocks form a section with a maximum thickness of about 3,580 m. The sediments were deposited in the Mexican Geosyncline, west of the Coahuila Peninsula of pre-Aptian age. The Villa Juarez Formation is overlain with angular unconformity by orthoquartzite, quartzose sandstone, and limestone lenses of the La Gloria Formation of Oxfordian age. The La Casita Formation, which is stratigraphically above the La Gloria Formation, probably ranges in age from late Oxfordian to early Neocomian. It consists of thin-bedded limestone, black shale, and varicolored sandstone, with intercalations of coal seams and abundant ammonites. The Lower Cretaceous rocks of the area comprise the Coahuila Series, La Pena Formation, Aurora Limestone, and Cuesta del Cura Formation. Neocomian and upper Aptian rocks are represented by thin-bedded limestone, marl, and shale of the Taraises, Las Vigas, Parritas, and La Pena Formations. This sequence of rocks is overlain with apparent conformity by the medium- to thick-bedded bank-type Aurora Limestone of middle to late Albian age. A notable change of facies occurs laterally in the upper Albian and lower Cenomanian rocks, the lithology of the Aurora Limestone grading westward into the thin-bedded limestone with wavy bedding planes and black chert intercalations that characterize the Cuesta del Cura Formation. An erosional unconformity developed on the surface of the Aurora Limestone and Cuesta del Cura Formation is covered by the Indidura and Caracol Formations of Turonian to Coniacian age. These consist or thin-bedded, platy limestone, shale, and marl beds, which grade upward into a thick sequence of poorly fossiliferous calcareous sandstone, siltstone, and shale. A period of intense folding and erosion preceded the deposit of the non-marine Ahuichila Formation, of probable late Eocene and early Oligocene age. This formation was deposited with marked angular unconformity on all the older rocks, including the Villa Juarez Formation. Both, porphyritic and equigranular igneous rocks in the form of dikes, sills, plugs, and stocks intrude the bedded rocks of the area. They range in composition from quartz rhyolite porphyry to andesite and from granadiorite to monzonite. The rocks around the intrusive bodies have been metamorphosed irregularly as far as 100 m from the igneous contacts. Irregular tactite aureoles occur around intrusive bodies in the Descubridora district, west of Cerritos de Los Victorinos, and in the Sierra del Mimbre. Marble and recrystallized limestone is found west of Descubridora and in the Bajio del Bailon, and hornfels has formed in Cerrito de La Cruz and Cerrito de Las Liebres near San Pedro del Gallo, as well as in the southern part of the Sierra del Mimbre. Folowing emplacement of the intrusive bodies mineralizing solutions reacting with sedimentary rocks gave origin to the different mineralized zones in the region. The beginning of the Laramide Orogeny in the San Pedro del Gallo region is marked by Late Cretaceous uplift, which probably continued until middle or late Eocene time. Compressive forces acting in an east-west to northeast-southwest direction folded the Mesozoic strata into a series of narrow asymmetrical anticlines and synclines overturned to the east, with axial, planes almost parallel to the borders of the Coahuila Peninsula. Thrusting and faulting were important in the vicinity of San Pedro del Gallo. There is no conclusive evidence of large-scale post-Triassic and pre-Laramide deformation in the area. Extrusion of lavas ranging in composition from basalt to rhyolite, accompanied by extensive block faulting, occurred during Miocene and Pliocene time. Late Tertiary uplift began during the Pliocene. The streams were rejuvenated and there was increased erosion, which caused, together with a change of climate, the overloading of some streams and local blocking of drainage by alluvial fans in the valleys, giving rise to the Santa Ines Formation. Erosion, more than deposition is the dominant event at present. Contact metasomatic silver, lead, and copper deposits in the Aurora Limestone have been mined in the Descubridora, Parranderas , and Sierra del Mimbre districts. Fluorite and barite have been extracted from veins in the La Gloria Formation and the Aurora Limestone. Thin beds and seams of coal in the La Casita Formation were mined within the town limits of San Pedro del Gallo. No important mining activity exists at present in the area studied. The area has never been tested for oil.

Geology of the Gore Canyon-Kremmling Area, Grand County, Colorado

Barclay, C. S. Venable January 1968 (has links)
The Gore Canyon-Kremmling area is in the southwestern portion of the Kremmling 15-minute quadrangle, Colorado. Precambrian rocks are biotite gneiss, the Boulder Creek Granodiorite, granophyre dikes, and quartz veins. The Boulder Creek Granodiorite intrudes the biotite gneiss, and both of these units are cut by north-northwest-trending, granophyre dikes and quartz veins. Biotite gneiss contains structure elements of a northwest and a northeast fold system. Lineations and foliations in the Boulder Creek Granodiorite are generally concordant to the northeast fold system of the gneiss. Late Paleozoic to Mesozoic and Mesozoic sedimentary formations, in ascending order and with their approximate thicknesses, are the State Bridge Formation, 15 feet; the Chinle and Chugwater Formations undivided, 0-95 feet; the Sundance Formations 0?-100 feet; the Morrison Formation, 250 feet; the Dakota Sandstone, 225 feet; the Benton Shale, 340 feet; the Niobrara Formation, 600 feet; and the Pierre Shale. Quaternary deposits are terrace, landslide, and modern flood-plain deposits. Laramide rock deformation is related to the Park Reuse uplift and includes faulting and, in the sediments, some folding. Some of the faults, including the regional Gore fault, are Precambrian structures reactivated in Laramide time.

The purpose of the research is to apply the newly developed tracing measures that surpass largely the MAUP problem. With unprecedented use in Brazil, these measures assess the level of sectoral location of manufacturing industry in the Greater S??o Paulo and the results show that the fabrication industries of automotive vehicles, trailers and bodies and clothing and accessories are more localized . On the other hand, the non-metallic minerals and pulp and paper segments have a higher dispersion in relation to the other. / Embora exista uma extensa variedade de medidas para se mensurar os n??veis de aglomera????o e localiza????o das firmas, o modifiable areal unit problem ???
