Machine Learning Application in Car Insurance Direct Marketing
Authors: Cheng Xiaotian 
Published: August 2024

Direct marketing such as telemarketing or mailing is an important method for companies to boost their business. Identifying the right proportion of target market could largely cut operational expense and improve efficiency. In this research, a secondary dataset from a car insurance company will be used to study this problem of market targeting. Basing on existing literature study, three classifiers are picked, Naïve Bayesian, Decision Tree, and Neural Network. Some literature researches on each of the algorithm are conducted. Later modelling experiments are performed to predict whether the final customer will purchase the insurance or not.

Policies and opportunities for physical activity engagement in Austrian schools: a census survey
Authors: Unger Alexandra , Schwarzenlander Andrea , Wilke Jan 
Published: August 2024

Background
Compelling evidence suggests that schools’ infrastructure and policy represent potential predictors of health and physical activity (PA) in children and adolescents. However, the translation of these findings into practice has not been examined. This study investigated the activity friendliness of Austrian schools.

Methods
Using a census sampling method, principals of Austrian schools (n = 342) were invited to participate in an online survey assessing 1) the availability of PA facilities (e.g. playgrounds, sports courts, swimming halls) and 2) applied PA policies (e.g. cooperation with sports clubs and involvement in PA projects).

Results
A total of 130 principals answered the survey which corresponds to a minimal response rate of 38%. While most schools (87.4%, n = 111) had a gymnastic hall, only one third (37%, n = 47) had access to a swimming hall. On average, the schools had 4.2 ± 2 PA facilities with significant variation between school types (i.e., high schools: 5 ± 2 vs. primary schools: 3.5 ± 2, p < 0.05). The most common facilities were meadow areas (89%, n = 113), sports fields (71.7%, n = 91), and playgrounds (64.6%, n = 82). Almost half of the schools were part of a PA project (e.g. “active break”, 45%, n = 56) and offered extracurricular PA programs and courses (54%, n = 67), but only one in five (22%, n = 27) regularly conducted fitness tests. PA policies varied between school types (p < 0.05) but almost all principals (94%, n = 117) would welcome a stronger promotion of activity friendliness at their school.

Conclusion
Schools are mostly activity-friendly regarding infrastructure although the limited possibilities for swimming lessons seem worrisome. PA promotion through projects, extracurricular PA offerings and fitness tests may be expanded.
Full vector low‐temperature magnetic measurements of geologic materials

Published: January 2015

AbstractThe magnetic properties of geologic materials offer insights into an enormous range of important geophysical phenomena ranging from inner core dynamics to paleoclimate. Often it is the low‐temperature behavior (<300 K) of magnetic minerals that provides the most useful and highest sensitivity information for a given problem. Conventional measurements of low‐temperature remanence are typically conducted on instruments that are limited to measuring one single‐axis component of the magnetization vector and are optimized for measurements in strong fields. These instrumental limitations have prevented fully optimized applications and have motivated the development of a low‐temperature probe that can be used for low‐temperature remanence measurements between 17 and 300 K along three orthogonal axes using a standard 2G Enterprises SQuID rock magnetometer. In this contribution, we describe the design and implementation of this instrument and present data from five case studies that demonstrate the probe's considerable potential for future research: a polycrystalline hematite sample, a polycrystalline hematite and magnetite mixture, a single crystal of magnetite, a single crystal of pyrrhotite, and samples of Umkondo Large Igneous Province diabase sills.
How ocean waves rock the Earth: Two mechanisms explain microseisms with periods 3 to 300 s
Authors: Ardhuin Fabrice , Gualtieri Lucia , Stutzmann Eléonore 
Published: January 2015

AbstractMicroseismic activity, recorded everywhere on Earth, is largely due to ocean waves. Recent progress has clearly identified sources of microseisms in the most energetic band, with periods from 3 to 10 s. In contrast, the generation of longer‐period microseisms has been strongly debated. Two mechanisms have been proposed to explain seismic wave generation: a primary mechanism, by which ocean waves propagating over bottom slopes generate seismic waves, and a secondary mechanism which relies on the nonlinear interaction of ocean waves. Here we show that the primary mechanism explains the average power, frequency distribution, and most of the variability in signals recorded by vertical seismometers, for seismic periods ranging from 13 to 300 s. The secondary mechanism only explains seismic motions with periods shorter than 13 s. Our results build on a quantitative numerical model that gives access to time‐varying maps of seismic noise sources.
Elliptical‐anisotropic eikonal phase velocity tomography
Authors: de Ridder S. A. L. , Biondi B. L. , Nichols D. 
Published: January 2015

AbstractWe formulated an anisotropic eikonal tomography approach for phase velocities based on a two‐dimensional elliptical‐anisotropic wave equation. We can fit the parameters of the ellipse directly from measured first‐order traveltime surface gradients and constrain these parameters to vary smoothly over space. The method is applied to Scholte waves in virtual seismic sources from stations in the Life of Field Seismic Ocean Bottom Cable array installed over the Ekofisk field. The fast directions of the azimuthally anisotropic Scholte wave velocities form a large circular pattern over the Ekofisk field. This pattern dominates the Scholte wave phase velocities at Ekofisk between 0.7 and 1.1 Hz. It results from the overburden stress state and from seafloor subsidence induced by decades of hydrocarbon extraction.
Deformation microstructures of glaucophane and lawsonite in experimentally deformed blueschists: Implications for intermediate‐depth intraplate earthquakes

Published: January 2015

AbstractA series of simple‐shear experiments on blueschist was performed at 400–500°C and 1–2.5 GPa to understand the deformation of seismically active, subducting oceanic crust. The experiments show that brittle microstructures are mainly found at pressures of 1–2 GPa, whereas ductile microstructures form at 2.5 GPa. J‐indices (a measure of fabric intensity) of glaucophane crystal preferred orientations change systematically with changing shear strain and confining pressure, and the angle between the slip plane and the shear direction of samples deformed at >2 GPa is similar to that of a strain ellipsoid. These results, together with the variable orientations of fine grains in a selected area electron diffraction image at 2 GPa, indicate that the brittle–ductile transition for glaucophane occurs at ~2 GPa. In contrast to this, lawsonite in the experiments show abundant fracturing in most specimens and a poor correlation between the J‐index, shear strain, and confining pressure. This demonstrates that lawsonite deformed by brittle failure under all experimental conditions. In the case of a starting material that has a strong fabric and deformed under dry experimental conditions, the brittle–ductile transition zone of glaucophane will be much shallower than 2 GPa. Therefore, our initial experimental results on the deformation behavior of blueschist indirectly support the dehydration embrittlement of subducting oceanic crust (glaucophane) as an important factor in the origin of intraplate earthquakes.
Salinity fronts in the tropical Pacific Ocean
Authors: Kao Hsun‐Ying , Lagerloef Gary S. E. 
Published: January 2015

AbstractThis study delineates the salinity fronts (SF) across the tropical Pacific, and describes their variability and regional dynamical significance using Aquarius satellite observations. From the monthly maps of the SF, we find that the SF in the tropical Pacific are (1) usually observed around the boundaries of the fresh pool under the intertropical convergence zone (ITCZ), (2) stronger in boreal autumn than in other seasons, and (3) usually stronger in the eastern Pacific than in the western Pacific. The relationship between the SF and the precipitation and the surface velocity are also discussed. We further present detailed analysis of the SF in three key tropical Pacific regions. Extending zonally around the ITCZ, where the temperature is nearly homogeneous, we find the strong SF of 1.2 psu from 7° to 11°N to be the main contributor of the horizontal density difference of 0.8 kg/m3. In the eastern Pacific, we observe a southward extension of the SF in the boreal spring that could be driven by both precipitation and horizontal advection. In the western Pacific, the importance of these newly resolved SF associated with the western Pacific warm/fresh pool and El Niño southern oscillations are also discussed in the context of prior literature. The main conclusions of this study are that (a) Aquarius satellite salinity measurements reveal the heretofore unknown proliferation, structure, and variability of surface salinity fronts, and that (b) the fine‐scale structures of the SF in the tropical Pacific yield important new information on the regional air‐sea interaction and the upper ocean dynamics.
Latent heating characteristics of the MJO computed from TRMM Observations
Authors: Barnes Hannah C. , Zuluaga Manuel D. , Houze Robert A. 
Published: January 2015

AbstractThe Tropical Rainfall Measurement Mission's (TRMM) Spectral Latent Heating algorithm shows the contributions of different forms of convection to the latent heating profiles of the Madden‐Julian Oscillation over the central Indian and West Pacific Oceans. In both oceanic regions, storms containing broad stratiform regions produce increased upper level heating during active Madden‐Julian Oscillation (MJO) phases. The largest differences between the central Indian and West Pacific Ocean heating are associated with heating produced by convective elements. Examination of the most extreme forms of convection shows that mesoscale organized convection often produces at least as much latent heat as young vigorous deep convection. Heating from nonextreme (often midlevel‐topped) convection is an important component of the MJO heating in both regions in all stages of the MJO. Over the central Indian Ocean the heating profile changes from having a maximum at 2 km due to nonextreme convection to a profile during the active stage that has two maxima: one at 3 km due to nonextreme convection and 6 km owing to numerous mature mesoscale storms with broad stratiform precipitation components. Over the West Pacific, the maxima at 3 and 6 km are present in all MJO stages, but the magnitude of the 6 km maximum sharply increases in the active MJO stage due to an increase in the number of storms with broad stratiform precipitation areas.
Evaluating uncertainty in convective cloud microphysics using statistical emulation

Published: January 2015

AbstractThe microphysical properties of convective clouds determine their radiative effects on climate, the amount and intensity of precipitation as well as dynamical features. Realistic simulation of these cloud properties presents a major challenge. In particular, because models are complex and slow to run, we have little understanding of how the considerable uncertainties in parameterized processes feed through to uncertainty in the cloud responses. Here we use statistical emulation to enable a Monte Carlo sampling of a convective cloud model to quantify the sensitivity of 12 cloud properties to aerosol concentrations and nine model parameters representing the main microphysical processes. We examine the response of liquid and ice‐phase hydrometeor concentrations, precipitation, and cloud dynamics for a deep convective cloud in a continental environment. Across all cloud responses, the concentration of the Aitken and accumulation aerosol modes and the collection efficiency of droplets by graupel particles have the most influence on the uncertainty. However, except at very high aerosol concentrations, uncertainties in precipitation intensity and amount are affected more by interactions between drops and graupel than by large variations in aerosol. The uncertainties in ice crystal mass and number are controlled primarily by the shape of the crystals, ice nucleation rates, and aerosol concentrations. Overall, although aerosol particle concentrations are an important factor in deep convective clouds, uncertainties in several processes significantly affect the reliability of complex microphysical models. The results suggest that our understanding of aerosol‐cloud interaction could be greatly advanced by extending the emulator approach to models of cloud systems.
Human sickness behavior: Ultimate and proximate explanations
Authors: Shattuck Eric C. , Muehlenbein Michael P. 
Published: January 2015

ABSTRACTSickness behavior, a coordinated set of behavioral changes in response to infection, lies at the intersection of immunology, endocrinology, and evolutionary biology. Sickness behavior is elicited by pro‐inflammatory cytokines, is thought to be an adaptive means of redirecting energy away from disadvantageous behaviors and toward mounting an effective immune response, and may be modulated by hormones, including testosterone and oxytocin. Research on sickness behavior in humans has lagged behind non‐human animal research due to methodological complexities. Here we review what is known about sickness behavior in humans, the effects of various hormones on sickness behavior, the possible role of cytokine gene variation in influencing sickness behavior responses, and the ways in which culture and gender norms could similarly influence these behavioral changes. We also propose methodologies for advancing further studies of sickness behavior in humans. Am J Phys Anthropol 157:1–18, 2015. © 2015 Wiley Periodicals, Inc.

ObjectiveMany forms of epilepsy are associated with aberrant neuronal connections, but the relationship between such pathological connectivity and the underlying physiological predisposition to seizures is unclear. We sought to characterize the cortical excitability profile of a developmental form of epilepsy known to have structural and functional connectivity abnormalities.MethodsWe employed transcranial magnetic stimulation (TMS) with simultaneous electroencephalographic (EEG) recording in 8 patients with epilepsy from periventricular nodular heterotopia and matched healthy controls. We used connectivity imaging findings to guide TMS targeting and compared the evoked responses to single‐pulse stimulation from different cortical regions.ResultsHeterotopia patients with active epilepsy demonstrated a relatively augmented late cortical response that was greater than that of matched controls. This abnormality was specific to cortical regions with connectivity to subcortical heterotopic gray matter. Topographic mapping of the late response differences showed distributed cortical networks that were not limited to the stimulation site, and source analysis in 1 subject revealed that the generator of abnormal TMS‐evoked activity overlapped with the spike and seizure onset zone.InterpretationOur findings indicate that patients with epilepsy from gray matter heterotopia have altered cortical physiology consistent with hyperexcitability, and that this abnormality is specifically linked to the presence of aberrant connectivity. These results support the idea that TMS‐EEG could be a useful biomarker in epilepsy in gray matter heterotopia, expand our understanding of circuit mechanisms of epileptogenesis, and have potential implications for therapeutic neuromodulation in similar epileptic conditions associated with deep lesions.

Published: January 2015

AbstractAmyloid fibrils associated with neurodegenerative diseases, such as Parkinson’s and Alzheimer’s, consist of insoluble aggregates of α‐synuclein and Aβ‐42 proteins with a high β‐sheet content. The aggregation of both proteins occurs by misfolding of the monomers and proceeds through the formation of intermediate oligomeric and protofibrillar species to give the final fibrillar cross‐β‐sheet structure. The morphological and mechanical properties of oligomers, protofibrils, and fibrils formed during the fibrillization process were investigated by thioflavin T fluorescence and circular dichroism in combination with AFM peak force quantitative nanomechanical technique. The results reveal an increase in the Young’s modulus during the transformation from oligomers to mature fibrils, thus inferring that the difference in their mechanical properties is due to an internal structural change from a random coil to a structure with increased β‐sheet content.
Reversible Control of Nanoparticle Functionalization and Physicochemical Properties by Dynamic Covalent Exchange
Authors: della Sala Flavio , Kay Euan R. 
Published: January 2015

AbstractExisting methods for the covalent functionalization of nanoparticles rely on kinetically controlled reactions, and largely lack the sophistication of the preeminent oligonucleotide‐based noncovalent strategies. Here we report the application of dynamic covalent chemistry for the reversible modification of nanoparticle (NP) surface functionality, combining the benefits of non‐biomolecular covalent chemistry with the favorable features of equilibrium processes. A homogeneous monolayer of nanoparticle‐bound hydrazones can undergo quantitative dynamic covalent exchange. The pseudomolecular nature of the NP system allows for the in situ characterization of surface‐bound species, and real‐time tracking of the exchange reactions. Furthermore, dynamic covalent exchange offers a simple approach for reversibly switching—and subtly tuning—NP properties such as solvophilicity.
Thermoset composites functionalized with carbon nanofiber sheets for EMI shielding
Authors: Zhao Zhongfu , Zhou Yongsen , Zhang Chunqing , Wang Zhanyue 
Published: January 2015

ABSTRACTCarbon nanofiber sheets were developed through filtering well‐dispersed carbon nanofiber (CNF) through filtering well‐dispersed aqueous solution of CNF particles with 0.4 μm hydrophilic polycarbonate membrane by the aid of high‐pressure air. They were used to functionalize composites by the resin transfer molding method. Their functionalized composites were characterized with scanning electron microscopy (SEM), four‐point probes and a vector network analyzer to measure their morphologies, electrical conductivity, and electromagnetic interference (EMI) shielding performance over the frequency range of 8–12 GHz (X band), respectively. Their morphologies show that CNF particles are overlapped and tightly connected with each other in their interconnected networks. The CNF sheets are exposed on the surface, although their networks are partially penetrated by polyester resins. Their electrical conductivity can be 3.0 ± 0.2 Scm−1 or so, much higher by ten orders of magnitude than the reported electrical conductivity of CNF‐filled composites. Their EMI shielding effectiveness slightly varies in a range of −30 dB to −35 dB as a function of frequency, much higher than that of most CNF or carbon nanotube–filled composites. © 2015 Wiley Periodicals, Inc.

ABSTRACTShape‐memory polymers (SMPs) that combine shape‐memory, biodegradability, and controlled drug release properties are very promising for medical and pharmaceutical application. Moreover, incorporation of antirestenotic drug into SMP biodegradable stent seems to be an interesting solution because of possibility to combine the mechanical support that provides stent and also drug elution. The aim of our study was to analyze the effect of incorporation of sirolimus into poly(l‐lactide‐co‐glycolide‐co‐trimethylene carbonate) on physicochemical and mechanical properties, degradation, and shape‐memory effect of the terpolymer. For this purpose, sirolimus was incorporated into the terpolymer by injection molding method. It has been demonstrated that drug‐free terpolymer after injection molding characterized insignificant changes in terpolymer composition. Degradation of materials during processing was not observed. Incorporation of drug molecules did not change shape‐memory properties of terpolymer. 1H‐ and 13C‐NMR spectra of poly(lactide‐co‐glycolide‐co‐trimethylene carbonate) confirmed that changes during degradation were similar for terpolymer and terpolymer with sirolimus. Sustained and regular release of sirolimus was observed. The developed material presents potential for biomedical and pharmaceutical applications. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.
