Towards the Semantic Enrichment of Existing Online 3D Building Geometry to Publish Linked Building Data
No full textCurrently, existing online 3D databases each have their own structure according to their own needs. Additionally, the majority of online content only has limited semantics. With the advent of Semantic Web technologies, the opportunity arises to semantically enrich the information in these databases and make it widely accessible and queryable. The goal is to investigate whether online 3D content from different repositories can be processed by a single algorithm to produce the desired semantics. The emphasis of this work is on extracting building components from generic 3D building geometry and publish it as Linked Building Data. An interpretation framework is proposed that takes as input any building mesh and outputs its components. More specifically, we use pretrained Support Vector Machines to classify the separate meshes derived from each 3D model. As a preliminary test case, realistic examples from several repositories are processed. The test results depict that, even though the building content originates from different sources and was not modeled according to any standards, it can be processed by a single machine learning application. As a result, building geometry in online repositories can be semantically enriched with component information according to classes from Linked Data ontologies such as BOT and PRODUCT. This is an important step towards making the implicit content of geometric models queryable and linkable over the Web.sponsorship: Fonds Wetenschappelijk Onderzoek|1S65917Nstatus: Publishe
Conformationally constrained butyrophenones with affinity for dopamine (D(1), D(2), D(4)) and serotonin (5-HT(2A), 5-HT(2B), 5-HT(2C)) receptors: synthesis of aminomethylbenzo[b]furanones and their evaluation as antipsychotics
No full textA series of novel conformationally restricted butyrophenones (6-aminomethyl-4,5,6,7-tetrahydrobenzo[b]furan-4-ones bearing 4-(6-fluorobenzisoxazolyl)piperidine, 4-(p-fluorobenzoyl)piperidine, 4-(o-methoxyphenyl)piperazine, 4-(2-pyridyl)piperazine, 4-(2-pyrimidinyl)piperazine, or linear butyro(or valero)phenone fragments) were prepared and evaluated as antipsychotic agents by in vitro assays for affinity for dopamine receptors (D(1), D(2), D(4)) and serotonin receptors (5-HT(2A), 5-HT(2B), 5-HT(2C)), by neurochemical studies, and by in vivo assays for antipsychotic potential and the risk of inducing extrapyramidal side effects. Potency and selectivity depended mainly on the amine fragment connected to the cyclohexanone structure. Compounds 20b, with a benzoylpiperidine moiety, and 20c, with a benzisoxazolyl fragment, were selective for 5-HT(2A) receptors. The in vitro and in vivo pharmacological profiles of N-[(4-oxo-4,5,6, 7-tetrahydrobenzo[b]furan-6-yl)methyl]-4-(p-fluorobenzoyl)piperidine (20b, QF1003B) and N-[(4-oxo-4,5,6, 7-tetrahydrobenzo[b]furan-6-yl)methyl]-4-(6-fluorobenzisoxazol-3-yl)p iperidine (20c, QF1004B) suggest that they may be effective as antipsychotic (neuroleptic) drugs

No full textAndiodrilus bogotaensis, a native species to the paramos around Bogotá was observed, by means of morpho-histologic studies, to lack spermateca. It was also observed that the Seminal vesicules of the large majority of the specimens studied are inhabited by the parasite Monocystis lumbrici, which is reported for the first time in Colombia for A. bogotaensi
Shortcuts to dynamic polarization
No full textDynamic polarization protocols aim to hyperpolarize a spin bath by transferring spin polarization from a well-controlled qubit such as a quantum dot or a color defect. Building on techniques from shortcuts to adiabaticity, we design fast and efficient dynamic polarization protocols in central spin models that apply to dipolarly interacting systems. The protocols maximize the transfer of polarization via bright states at a nearby integrable point, exploit the integrability-breaking terms to reduce the statistical weight on dark states that do not transfer polarization, and realize experimentally accessible local counterdiabatic driving through Floquet engineering. A master equation treatment suggests that the protocol duration scales linearly with the number of bath spins with a prefactor that can be orders of magnitude smaller than that of unassisted protocols. This work opens pathways to cool spin baths and extend qubit coherence times for applications in quantum information processing and metrology.DMR-1752759 - National Science Foundation; FA9550-20-1-0235 - Department of Defense/AFOSRFirst author draf
