Dynamic Environment Mapping for Augmented Reality Applications on Mobile Devices (2018)

Augmented Reality is a topic of foremost interest nowadays. Its main goal is to seamlessly blend virtual content in real-world scenes. Due to the lack of computational power in mobile devices, rendering a virtual object with high-quality, coherent appearance and in real-time, remains an area of active research. In this work, we present a novel pipeline that allows for coupled environment acquisition and virtual object rendering on a mobile device equipped with a depth sensor. While keeping human interaction to a minimum, our system can scan a real scene and project it onto a two-dimensional environment map containing RGB+Depth data. Furthermore, we define a set of criteria that allows for an adaptive update of the environment map to account for dynamic changes in the scene. Then, under the assumption of diffuse surfaces and distant illumination, our method exploits an analytic expression for the irradiance in terms of spherical harmonic coefficients, which leads to a very efficient rendering algorithm. We show that all the processes in our pipeline can be executed while maintaining an average frame rate of 31Hz on a mobile device.
Quality of life and satisfaction of patients two years after endodontic and dental implant treatments performed by experienced practitioners (2022)

This study demonstrated a high satisfaction and long-term quality of life of patients undergoing both DI and RCT if treatments provide a functional balance and are performed by experienced practitioners. Very importantly, all participants had received both treatment modalities and being their own control eliminates individual variability.
Associations Between Obesity and Changes in Adult BMI Over Time and Colon Cancer Risk (2008)

Obesity has been associated with increased colon cancer risk in epidemiological studies; however, the specific time periods during which obesity may be most relevant as well as how changes in adult body size over time affect colon cancer risk have not been well explored. We evaluated potential associations between BMI in each age decade(20s, 30s, 40s, 50s, and 2 years before study recruitment ("recruitment period")) and in BMI changes over timeand colon cancer risk in a population-based case-control study comprising 438 cases and 491 controls. We found that obese (BMI>or=30.0 kg/m2) compared to normal (BMI>or=18.5 to <25.0 kg/m2) body size at the recruitment period was associated with increased colon cancer risk (odds ratio (OR)=1.54; 95% confidence interval (CI)=1.03-2.31; P=0.03). No associations were observed for obese body size in the other age decades. An increased risk was found for changes in BMI between the 30s decade and the recruitment period of 5-10 kg/m2 (OR=1.54; 95%CI=1.02-2.34; P=0.04) and >10 kg/m2 (OR=2.40; 95% CI=1.23-4.66; P=0.01) (P trend=0.01). Stratification by gender revealed that BMI changes>10 kg/m2 increased risk in women but not men. Similar results were found for BMI changes between the 20s decade and the recruitment period but effect sizes were smaller. Our results provide additional support to obesity's role in colon cancer and suggest large body size increases exceeding 10 kg/m2 may potentially be more important after age 30, particularly among women; however, prospective studies with sex hormone, growth factor, and pro-inflammatory biomarkers are needed to provide insights to the underlying biological mechanism(s).
Proposal for a joint ESA/NASA technology demonstration experiment: Slosh test orbital facility (STOF) (1992)

Responding to the 'Call for Proposals for the In-Orbit Technology Demonstration Programme, Phase 2 (TDP2)' of the European Space Agency (ESA), the Dutch National Aerospace Laboratory (NLR) submitted a plan for the realisation of the 'Slosh Orbital Test Facility (STOF)'. 

This proposal describes a small free flying spacecraft that will be ejected from a Hitchhiker cross bay structure (HH-M). The spacecraft, denoted 'SLOSHSAT' , is the basic component of STOF. SLOSHSAT is primarily designed for the investigation of forces exerted upon a manoeuvring spacecraft by a liquid sloshing in a partially filled tank. However, SLOSHSAT has the growth potential for becoming a general facility for experimental spacecraft dynamics.

In view of the potential common interest, ESA proposed to carry out this project in cooperation with NASA (sponsored by NASA-HQ, code R).
Promoter Polymorphism of RRM1 Gene in Korean Lung Cancer Population (2006)

Background: LOH11A is a region with frequent allele loss (>75%) in lung cancer that is located on the centromeric part of chromosome 11p15.5. Clinical and cell biological studies suggest that this region contains a gene associated with metastatic tumor spread. RRM1 encoding the M1 subunit of ribonucleotide reductase, which is an enzyme that catalyses the rate-limiting step in deoxyribonucleotide synthesis, is located in the LOH11A region. Methods: Polymorphisms were found at nucleotide position (-)37 (C/A) an d (-)524 (C/T) from the beginning of exon 1 of the RRM1 gene that might regulate the expression of RRM1. We studied the polymorphisms in 127 Korean individuals (66 lung cancer and 61 normal controls) and compared with those of 140 American patients with lung cancer. Results: CC, AC and AA were found at the (-)37 position in 64(50.4%), 55(43.3%), and 8(6.3%) out of 127 Korean individuals (66 cancer, 61 non-cancer patients), respectively. There was a similar frequency of allele A at (-)37 in the American(27.9%) and Korean population(28.0%). CC, CT and TT was found at the (-)524 position in 24(18.9%), 44(34.6%), and 59(46.5%) out of the 127 Korean individuals, respectively. There was a similar frequency of allele C at (-)524 in the American(34.6%) and Korean population(36.2%). There was no difference in the frequency of the (-)37 and (-)524 genotypes between the cancer and non-cancer group. However there was a significant correlation of the genotypes between (-)37 and (-)524 (p<0.001), which suggests the possible coordination of these polymorphisms in the regulation of the promoter activity of the RRM1 gene. Conclusion: RRM1 promoter polymorphisms were not found to be significant risk factors for lung cancer. However, a further study of the promoter activity and expression of the RRM1 gene according to the pattern of the polymorphism will be needed. (Tuberc Respir Dis 2006; 61: 248-255)
Moderate velocity oblique impact sliding: Production of shocked meteorite textures and palaeomagnetically important metallic spherules in planetary regoliths (2013)

Abstract We detail the production of metallic spherules in laboratory oblique shock impact experiments, and their applicability (1) to textures in a partly shock‐melted chondritic meteorite and (2) to the occurrence of palaeomagnetically important fine iron or iron alloy particles in the lunar regolith. Samples recovered from 29–44 GPa, 800 ns, experiments revealed melting and textures reminiscent of metallic spherules in the Yanzhuang H‐chondrite, including “dumbbell” forms and other more complex morphologies. Our experiments demonstrate that metallic spherules can be produced via oblique impact sliding at lower velocities (1.85 km s −1 ) than are generally assumed in previous work associated with bulk‐shock melting, and that oblique impact sliding is a viable mechanism for producing spherules in shock‐induced veins in moderately shocked meteorites. Significantly, our experiments also produced fine metallic (iron alloy) spherules within the theoretical narrow size range (a few tens of nanometers for slightly ellipsoidal particles) for stable single‐domain ( SSD ) particles, which are the most important palaeomagnetically, since they can record lunar and planetary magnetic fields over geological time periods. The experiments also produced spherules consistent with superparamagnetic ( SP ) and multidomain ( MD ) particle sizes. The fine SSD and SP particles on the lunar surface are currently thought to have been formed predominantly by space weathering processes. Our experiments suggest that oblique shock impact sliding may be a further means of producing the SSD and SP iron or iron alloy particles observed in the lunar regolith, and which are likely to occur in the regoliths of Mercury and other planetary bodies.
Effects of arbuscular-mycorrhizal glomus species on drought tolerance: physiological and nutritional plant responses (1995)

The tolerance of lettuce plants (Lactuca sativa L. cv. Romana) to drought stress differed with the arbuscular-mycorrhizal fungal isolate with which the plants were associated. Seven fungal species belonging to the genus Glomus were studied for their ability to enhance the drought tolerance of lettuce plants. These fungi had different traits that affected the drought resistance of host plants. The ranking of arbuscular-mycorrhizal fungal effects on drought tolerance, based on the relative decreases in shoot dry weight, was as follows: Glomus deserticola > Glomus fasciculatum > Glomus mosseae > Glomus etunicatum > Glomus intraradices > Glomus caledonium > Glomus occultum. In this comparative study specific mycorrhizal fungi had consistent effects on plant growth, mineral uptake, the CO(inf2) exchange rate, water use efficiency, transpiration, stomatal conductance, photosynthetic phosphorus use efficiency, and proline accumulation under either well-watered or drought-stressed conditions. The ability of the isolates to maintain plant growth effectively under water stress conditions was related to higher transpiration rates, levels of leaf conductance, and proline, N, and P contents. Differences in proline accumulation in leaves among the fungal symbioses suggested that the fungi were able to induce different degrees of osmotic adjustment. The detrimental effects of drought were not related to decreases in photosynthesis or water use efficiency. Neither of these parameters was related to P nutrition. The differences in P and K acquisition, transpiration, and stomatal conductance were related to the mycorrhizal efficiencies of the different fungi. Our observations revealed the propensities of different Glomus species to assert their protective effects during plant water stress. The greater effectiveness of G. deserticola in improving water deficit tolerance was associated with the lowest level of growth reduction (9%) under stress conditions. The growth of plants colonized by G. occultum was reduced by 70% after a progressive drought stress period. In general, the different protective effects of the mycorrhizal isolates were not associated with colonizing ability. Nevertheless, G. deserticola was the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.
Identity Federation Broker for Service Cloud. (2010)

As the wide adoption of in-cloud services (e.g., software-as-a-service), some major identity related issues are brought up. For enterprises, it usually introduces additional cost and risk to manage identities in services. For service providers, typical pairwise identity federation solutions are not scalable to support single sign-on, service composition, etc. among services for large environment like service cloud. This paper proposes an identity federation broker that introduces a trusted third party as a trust broker to simplify the management of identity federation in a user centric manner. With this solution, the cost and risk of federated identity management for both enterprises and service providers could be significantly reduced. A detailed scenario implementation is given to demonstrate the feasibility of the solution. Moreover, the vulnerability analysis shows how the solution can resist the typical security attacks.

G Protein Signaling Events Are Activated at the Leading Edge of Chemotactic Cells (1998)

Directional sensing by eukaryotic cells does not require polarization of chemoattractant receptors. The translocation of the PH domain-containing protein CRAC in D. discoideum to binding sites on the inner face of the plasma membrane reflects activation of the G protein-linked signaling system. Increments in chemoattractant elicit a uniform response around the cell periphery. Yet when cells are exposed to a gradient, the activation occurs selectively at the stimulated edge, even in immobilized cells. We propose that such localized activation, transmitted by the recruitment of cytosolic proteins, may be a general mechanism for gradient sensing by G protein-linked chemotactic systems including those involving chemotactic cytokines in leukocytes.
Anti-Racism in Higher Education: A Model for Change (2020)

Racism continues to persist in higher education and traditional diversity initiatives that focus only on support resources and tolerance training continue to fall short in making lasting change on college and university campuses. The purpose of this scholarly paper is to present a model for change within higher education that distributes leadership and institutional power across racial lines and enlightens the White community about systemic inequities.
Effects of Endoscopic Sinus Surgery and Device on Irrigation (2008)

Objective 1) Assess the effect of endoscopic sinus surgery (ESS) on the distribution of topical solutions to the para‐nasal sinuses. 2) Understand differences in topical solution distribution to the para‐nasal sinuses using various delivery devices. Methods Ten cadaver sinus systems were irrigated with radio‐opaque contrast prior to any surgery, after ESS, and following modified medial maxillectomy. Delivery of contrast was via pressurized spray, neti pot and squeeze bottle techniques for each surgical state. CT scans were performed before and after each irrigation using a portable CT machine. Blinded assessments were made for distribution of contrast within the sinuses. A semi‐quantitative grading scale was used to assess contrast distribution to each of 5 sinus regions (maxillary, anterior ethmoid, posterior ethmoid, sphenoid and frontal). Results Total sinus distribution of contrast was significantly greater post‐ESS as compared to the un‐operated state (p&lt;0.001). Sphenoid and frontal sinus distribution was most affected by surgery. Delivery device influenced contrast distribution, with neti pot and squeeze bottle techniques providing greater distribution than pressurized spray (p&lt;0.001). Frontal sinus penetration was greater post‐ESS (p=0.017) and neti pot delivery was the most effective frontal delivery device (p&lt;0.001). Conclusions ESS greatly enhances the delivery of nasal solutions, regardless of delivery device. Limited distribution to the sinuses exists without concomitant ESS, especially for sprays. Squeeze bottle/neti pot use, post‐ESS, offers a greatly enhanced ability to deliver solutions to the para‐nasal sinuses.

Samsoving, smokk, amming og krybbedød – finnes det en sammenheng? (2005)

Hvert år dør omtrent 20 barn i krybbedød i Norge. Påstandene om sammenhenger er mange blant fagfolk: Samsoving øker risiko for krybbedød, samsoving fremmer vellykket amming, bruk av smokk kan forhindre krybbedød, bruk av smokk hindrer vellykket amming og amming kan beskytte mot krybbedød. Hensikten med denne rapporten var å vurdere tilgjengelig forskning på samsoving og bruk av smokk og hvilke effekter det har på amming og risiko for krybbedød. En bredt sammensatt utredningsgruppe har utarbeidet denne metodevurderingen.
Study of PZT coated membrane structures for micromachined ultrasonic transducers [medical imaging] (2001)

Test structures for piezoelectric micromachined ultrasonic transducers have been fabricated and investigated. The basic element consists of a silicon membrane coated with a [100] textured Pb(ZrTi)O/sub 3/ (PZT) thin film deposited by sol-gel techniques. Dense and [100]-textured PZT films are obtained up to a thickness of 4 /spl mu/m. Cantilever and membrane test structures were simulated by finite element analysis (FEA). Characteristic material properties have been derived comparing experimental and simulation results. The findings are used to optimize a transducer design for medical imaging in the range of 5 MHz.
In vivo occurrence of p16 (MTS1) and p15 (MTS2) alterations preferentially in non-small cell lung cancers. (1995)

Frequent homozygous deletions of the p16 (MTS1) gene encoding a cyclin-dependent kinase inhibitor were recently reported in various tumor cell lines including examples derived from lung cancers, but direct evidence for their occurrence in lung cancer patients has not been reported thus far. In the present study, alterations of p16 and/or p15, a p16-related cyclin-dependent kinase, were observed not only in lung cancer cell lines but also in the corresponding tumor specimens in vivo, excluding the possibility of in vitro artifacts. Interestingly, a clear specificity was also noted in terms of the affected histological subtype; i.e., only non-small cell lung cancers carried alterations (6 of 20 as compared to 0 of 20 small cell lung cancer cell lines).
Maximum-SNR-based adaptive protocol with subcarrier selection for OFDM cooperative communications (2008)

In this paper, we propose a maximum signal-to-noise-ratio (SNR)-based adaptive protocol for two-user OFDM cooperative communications with fairness. Specifically, two users in this system mutually act as a source or relay in each time, where the transmission rate and the total transmit power remain constant. The proposed protocol operates by adaptively selecting a half of maximum-SNR subcarriers in each OFDM frame to help transmitting the partner information, and the remaining subcarriers are used by the source node. In addition, the proposed protocol yields a maximum average total SNR to a selected channel. Simulation results show that the proposed adaptive protocol provides a lower symbol error rate (SER) compared with existing fixed-subcarrier-selection protocols.
Single-photon detection using a semiconductor quantum dot, optically gated, field-effect transistor (2006)

Long-period fiber gratings for simultaneous temperature and bend sensing (2000)

Long-period fiber gratings (LPGs) written into commercially available boron co-doped fibers operating at wavelengths &lt; 1.1 micrometers are shown to exhibit high temperature- and bending-sensitivities. Each resonant attenuation band of such a LPG was observed to split into two when the LPG was bent. The split attenuation bands' separation increased significantly with increasing bend curvature, while the central wavelengths of the split bands provided a measure of temperature. This effect is exploited to allow simultaneous measurement of temperature and bending in smart structure applications. The demonstrated novel sensor system is simple and low cost.
Impurity and neutral effects on the dissipative drift wave in tokamak edge plasmas (1992)

Possible destabilizing mechanisms for the linear electrostatic dissipative drift waves (in tokamak edge plasmas) are investigated in slab geometry. The effects of processes such as ionization, charge exchange, radiation, and rippling are examined. In particular, the impurity condensation associated with radiation cooling is evaluated appropriately for the drift wave ordering, which is found to be an important driving mechanism in contrast to the results of earlier studies [R. J. Thayer and P. H. Diamond, Phys. Rev. Lett. 65, 2784 (1990)]. It is also shown that the role of ionization is quite complicated, and depends strongly on the manner in which the equilibrium is achieved. The linear eigenmode equation is studied both analytically and numerically. For the range of parameters relevant to TEXT tokamak [K. W. Gentle, Nucl. Fusion Technol. 1, 479 (1981)], both the charge exchange and the rippling effect are found to be unimportant for instability.
Protein Dynamics from Accurate Low-Field Site-Specific Longitudinal and Transverse Nuclear Spin Relaxation (2019)

Nuclear magnetic relaxation provides invaluable quantitative site-specific information on the dynamics of complex systems. Determining dynamics on nanosecond time scales requires relaxation measurements at low magnetic fields incompatible with high-resolution NMR. Here, we use a two-field NMR spectrometer to measure carbon-13 transverse and longitudinal relaxation rates at a field as low as 0.33 T (proton Larmor frequency 14 MHz) in specifically labeled side chains of the protein ubiquitin. The use of radiofrequency pulses enhances the accuracy of measurements as compared to high-resolution relaxometry approaches, where the sample is moved in the stray field of the superconducting magnet. Importantly, we demonstrate that accurate measurements at a single low magnetic field provide enough information to characterize complex motions on low nanosecond time scales, which opens a new window for the determination of site-specific nanosecond motions in complex systems such as proteins.
