Improving the scalability of platform attestation (2008)

In the process of platform attestation, a Trusted Platform Module is a performance bottleneck, which causes enormous delays if multiple simultaneously attestation requests arrive in a short period of time. In this paper we show how the scalability of platform attestation can be improved. In this context, we propose three protocols that enable fast and secure integrity reporting for servers that have to handle many attestation requests. We implemented all of our protocols and compared them in terms of security and performance. Our proposed protocols enable a highly frequented entity to timely answer incoming attestation requests.

The <i>FLF</i> MADS Box Gene: A Repressor of Flowering in Arabidopsis Regulated by Vernalization and Methylation (1999)

A MADS box gene, FLF (for FLOWERING LOCUS F ), isolated from a late-flowering, T-DNA-tagged Arabidopsis mutant, is a semidominant gene encoding a repressor of flowering. The FLF gene appears to integrate the vernalization-dependent and autonomous flowering pathways because its expression is regulated by genes in both pathways. The level of FLF mRNA is downregulated by vernalization and by a decrease in genomic DNA methylation, which is consistent with our previous suggestion that vernalization acts to induce flowering through changes in gene activity that are mediated through a reduction in DNA methylation. The flf-1 mutant requires a greater than normal amount of an exogenous gibberellin (GA3) to decrease flowering time compared with the wild type or with vernalization-responsive late-flowering mutants, suggesting that the FLF gene product may block the promotion of flowering by GAs. FLF maps to a region on chromosome 5 near the FLOWERING LOCUS C gene, which is a semidominant repressor of flowering in late-flowering ecotypes of Arabidopsis.
Efficient Compression of 3D Dynamic Mesh Sequences (2007)

Sample frames of the animations used for the analysis. From left to right: dance with 14, dolphin with 9, chicken with 10 and cow with 6 clusters. Each cluster is colored differently and encoded separately. This paper presents a new compression algorithm for 3D dynamic mesh sequences based on the local principal component analysis (LPCA). The algorithm clusters the vertices into a number of clusters using the local similarity between the trajectories in a coordinate system that is defined in each cluster, and thus transforms the original vertex coordinates into the local coordinate frame of their cluster. This operation leads to a strong clustering behavior of vertices and makes each region invariant to any deformation over time. Then, each cluster is efficiently encoded with the principal component analysis. The appropriate numbers of basis vectors to approximate the clusters are optimally chosen using the bit allocation process. For further compression, quantization and entropy encoding are used. According to the experimental results, the proposed coding scheme provides a significantly improvement in compression ratio over existing coders.
MicroRNA Profiling of Human Intrahepatic Cholangiocarcinoma Cell Lines Reveals Biliary Epithelial Cell-specific MicroRNAs (2009)

Intrahepatic cholangiocarcinoma (ICC), which arises in the small bile ducts of the liver, is the second most common liver malignancy. Although modulation of microRNA (miRNA) expression has been shown to be a potent sign of malignant tumors, miRNA profiles of ICC remains unclear. We performed sequencing analysis of the small RNA libraries of 2 ICC cell lines (HuCCT1 and MEC) and one normal intrahepatic biliary epithelial cell line (HIBEpiC) to produce the miRNA profiles of ICC in vitro. Furthermore, by means of the real-time polymerase chain reaction (PCR) we validated the differential expression of miRNAs cloned exclusively or predominantly from each of the cell lines. A total of 35,759 small RNA clones were obtained from the 3 cell lines. We identified 27 miRNAs that were expressed exclusively or predominantly in each cell line. Subsequent validation with the real-time PCR confirmed that the miRNAs hsa-miR-22, -125a, -127, -199a, -199a*, -214, -376a, and -424 were expressed specifically in HIBEpiC but were downregulated in the ICC cell lines. Our study provides important information for facilitating studies of the functional role(s) of miRNAs in carcinogenesis of the hepatobiliary system. The biliary epithelial cell-specific miRNAs identified in this study may serve as potential biomarkers for ICC.
Punch Grafting versus Suction Blister Epidermal Grafting in the Treatment of Stable Lip Vitiligo (2007)

Although both the procedures are effective in lip vitiligo, PSG gives a better color match than SBEG.
Migration of Chemical Compounds from Packaging Polymers during Microwave, Conventional Heat Treatment, and Storage (2013)

Polymeric packaging protects food during storage and transportation, and withstands mechanical and thermal stresses from high-temperature conventional retort or microwave-assisted food processing treatments. Chemical compounds that are incorporated within polymeric packaging materials to improve functionality, may interact with food components during processing or storage and migrate into the food. Once these compounds reach a specified limit, food quality and safety may be jeopardized. Possible chemical migrants include plasticizers, antioxidants, thermal stabilizers, slip compounds, and monomers. Chemical migration from food packaging is affected by a number of parameters including the nature and complexity of food, the contact time and temperature of the system, the type of packaging contact layer, and the properties of the migrants. Researchers study the migration of food-packaging compounds by exposing food or food-simulating liquids to conventional and microwave heating and storage conditions, primarily through chromatographic or spectroscopic methods; from these data, they develop kinetic and risk assessment models. This review provides a comprehensive overview of the migration of chemical compounds into food or food simulants exposed to various heat treatments and storage conditions, as well as a discussion of regulatory issues.

Cold-start news recommendation with domain-dependent browse graph (2014)

Online social networks and mash-up services create opportunities to connect different web services otherwise isolated. Specifically in the case of news, users are very much exposed to news articles while performing other activities, such as social networking or web searching. Browsing behavior aimed at the consumption of news, especially in relation to the visits coming from other domains, has been mainly overlooked in previous work. To address that, we build a BrowseGraph out of the collective browsing traces extracted from a large viewlog of Yahoo News (0.5B entries), and we define the ReferrerGraph as its subgraph induced by the sessions with the same referrer domain. The structural and temporal properties of the graph show that browsing behavior in news is highly dependent on the referrer URL of the session, in terms of type of content consumed and time of consumption. We build on this observation and propose a news recommender that addresses the cold-start problem: given a user landing on a page of the site for the first time, we aim to predict the page she will visit next. We compare 24 flavors of recommenders belonging to the families of content-based, popularity-based, and browsing-based models. We show that the browsing-based recommender that takes into account the referrer URL is the best performing, achieving a prediction accuracy of 48% in conditions of heavy data sparsity.
Should we be promoting embryo transfer at blastocyst stage? (2015)

Improved laboratory standards and better culture media have made extended culture to blastocyst stage a reality to identify embryos with maximum implantation potential. The strategy of extended culture has become more popular across the world at a time when regulatory bodies have emphasized the need to increase the uptake of elective single embryo transfer, minimize complications associated with multiple births and aim for a healthy singleton live-birth as the preferred outcome in IVF. New data on perinatal outcomes suggest that pregnancies after embryo transfer at blastocyst stage are associated with a higher risk of preterm delivery, large for gestational age babies, monozygotic twins and altered sex ratio compared with those following embryo transfers at cleavage stage. In addition, concerns have been raised of increased congenital anomalies and epigenetic modifications with embryo transfer at blastocyst stage. Twenty-four years on from the first embryo transfer at blastocyst stage, we examine the reasons for extended embryo culture, evaluate the risks and benefits of this strategy and suggest the need to reconsider this policy in the interests of fetal safety.
Automatic assessment in engineering mathematics: evaluation of the impact (2010)

We study the impact of a web-based automatic assessment system STACK in teaching mathematics for engineering students. We describe several uses of automatic assessment which have been tested in Aalto University during the past few years. We measure the impact of e-assessment to learning outcomes in engineering mathematics. This question is motivated by the practical need to show that the system is, in general, worth the effort invested but also our wish to better understand the learning process. The secondary aim is to obtain information about the different factors affecting the learning outcomes that would be useful in further improving mathematics teaching. Our goal is to show that such system can significantly activate students, allow much increased flexibility in practical arrangements of teaching, and facilitate innovative practices in, e.g., diagnostic testing and grading students’ work.
User behavior analysis of location aware search engine (2003)

The rapid growth of Internet access from mobile users has emphasised the importance of location specific information on the Web. A unique Web service called Mobile Info Search (MIS) from NTT Laboratories gathers information and provides location aware search facilities. We performed association rule mining and sequence pattern mining against an access log which was accumulated at the MIS site in order to get insight into the behavior of mobile users regarding spatial information on the Web. Details of the Web log mining process and the rules we derived are reported in this paper.
Development of the high-temperature phase of hexagonal manganites (2004)

Reports about the ferroelectric ordering temperatures in the multiferroic hexagonal $R{\mathrm{MnO}}_{3}$ system are controversial: transition temperatures varying between $\ensuremath{\approx}900\mathrm{K}$ and $\ensuremath{\approx}1300\mathrm{K}$ are reported for the same material. To elucidate the structural changes leading to ferroelectric distortions in hexagonal manganites, we calculate the irreducible representations of the distortions from the possible high-temperature symmetry ${P6}_{3}/mmc$ to the low-temperature symmetry ${P6}_{3}\mathrm{cm}.$ There are four different orthogonal modes, of which only one allows a spontaneous electric polarization. Structure refinements and an accurate statistical analysis of neutron powder-diffraction data of ${\mathrm{TmMnO}}_{3},$ based on this group-theoretical analysis, reveal two phase transitions: We extrapolate a polar to nonpolar transition temperature of ${T}_{\mathrm{npt}}=1433(27)\mathrm{K},$ where the hexagonal bitetrahedra start to tilt, while the ferroelectric distortion appears at ${T}_{\mathrm{FE}}=1050(50)\mathrm{K}.$ For $R=\mathrm{Lu},$ Yb the tilt of the bitetrahedra and the buckling of the R layers as well as the ferroelectric distortion were extrapolated to comparable temperatures.
Link Prediction Using Protected Location History (2013)

This paper investigates the link prediction problem in location-based social networking services (LBSNS) with protected location history. While former approaches mainly utilize the accurate locations, the relevant data we analyzed are modeled by a location privacy protection model called k-anonymous spatial-temporal cloaking model (KSTCM) which perturbs the location-related records on both temporal and spatial dimensions. We also propose a KSTCM-based co-located relationship model based on which various contextual features are extracted to help building the prediction model. Furthermore, we study the extent to which link between two users can be inferred from the co-located situation in space, time and degree of privacy protection. The experimental results show that our link prediction model can obtain a very high accuracy.
Feasibility tests of transmission x-ray photoelectron emission microscopy of wet samples (2000)

We performed feasibility tests of photoelectron emission spectromicroscopy of wet samples in the water window (285–532 eV) soft x-ray spectral region. Water was successfully confined in an ultrahigh vacuum compatible compartment with x-ray transparent sides. This water cell was placed in the MEPHISTO spectromicroscope in a transmission geometry, and complete x-ray absorption spectra of the water window region were acquired. We also show micrographs of test samples, mounted outside of the compartment, and imaged through the water. This technique can be used to study liquid chemistry and, at least to the micron level, the microstructure of wet samples. Possibilities include cells in water or buffer, proteins in solution, oils of tribological interest, liquid crystals, and other samples not presently accessible to the powerful x-ray photoelectron emission spectromicroscopy technique.
Behavior of a drop on an oscillating solid plate (2006)

Oscillations of a nominally hemispherical, inviscid drop on a solid plate are considered accounting for the contact line dynamics. Hocking boundary conditions hold on the contact line: the velocity of the contact line is proportional to the deviation of the contact angle from its equilibrium value. Natural oscillations of a drop are studied, and both eigenfrequencies and damping ratios are determined for the axisymmetric modes. The linear oscillations caused by normal vibration of the substrate are considered. Well-pronounced resonant phenomena are revealed. The nonlinear oscillations of a drop are studied.
Optimizing 13.5nm laser-produced tin plasma emission as a function of laser wavelength (2007)

Extreme ultraviolet lithography requires a light source at 13.5nm to match the proposed multilayer optics reflectivity. The impact of wavelength and power density on the ion distribution and electron temperature in a laser-produced plasma is calculated for Nd:YAG and CO2 lasers. A steady-state figure of merit, calculated to optimize emission as a function of laser wavelength, shows an increase with a CO2 laser. The influence of reduced electron density in the CO2 laser-produced plasma is considered in a one-dimensional radiation transport model, where a more than twofold increase in conversion efficiency over that attainable with the Nd:YAG is predicted.
Analyzing Human Trust of Autonomous Systems in Hazardous Environments (2008)

Autonomous systems are becoming more prevalent in our everyday lives. From agent software that collects news for us or bids for us in online auctions to robots that vacuum our floors and may help care for us when we grow old, autonomous agents promise to play a greater role in our lives in the future. Yet, there is ample evidence that many people do not trust autonomous systems – especially in environments where human lives may be put at risk. Examples include search-and-rescue operations at disaster sites, military operations in a combat zone, and caregiving scenarios where a human’s life depends on the care given by an autonomous system. This paper uses previous work on trust in multi-agent systems as a basis for examining the factors that influence the trust humans have in autonomous systems. Some of the technical and ethical implications of relying on autonomous systems (especially in combat areas) are considered. Some preliminary results from a simulation of a firefighting scenario where humans may need to rely upon robots are used to explore the effects of the different factors of human trust. Finally, directions for future research in human trust of autonomous systems are discussed.
Improved extended HMM composition by incorporating power variance (2002)

The paper describes a way of improving extended HMM composition that can precisely adapt HMMs to both noisy and distorted speech. To do this, the authors incorporate the variance of power into extended HMM composition using quantization to approximate the Gaussian distribution of the 0th order cepstrum. Consequently, a distribution of noisy speech is approximated in the linear spectral domain as a mixture of log normal distributions. This method is evaluated by a four-digit recognition experiment when the number of digits is known. Two types of noise, computer room noise and car noise, are used and noisy and distorted speech data is made by adding these types of noise to speech data recorded using a boundary microphone. Results show that the proposed method improves recognition rates for noisy and distorted speech compared with their previous method.
Urban traffic simulation with psycho-physical vehicle-following models (1997)

A psycho-physical vehicle-following model tries to capture both the physical and human components of congested-traffic simulations. These models determine the reactions of the vehicle driver depending on the vehicle's state. The state of a vehicle can be determined by the distance and by the difference in speed, in comparison to the leading vehicle. If the vehicle state changes, the driver must react. The reaction of the driver is to calculate a new value for acceleration. There are two different classical methods of time advance to calculate the state changes. This paper examines the effect of these methods on simulation run times and simulation results. Empirical experiments were done on a SLX-based simulation model.

A giant magnetoresistance sensor for high magnetic field measurements (2000)

We used giant magnetoresistance in a magnetic field sensor able to measure large fields of up to several kG. We deposit spin valves with a magnetic multilayer with perpendicular anisotropy as one ferromagnet and a material with in-plane anisotropy as the other ferromagnet. For magnetic fields along the film normal, the multilayer’s magnetization is fixed perpendicular while the magnetic layer with in-plane anisotropy is rotated towards out-of-plane magnetization. The device response is nearly linear with applied field and determines both the magnitude and sign of the field, making it attractive for measuring large magnetic fields.
Evaluating the Usage, Utility and Usability of Web-Technologies to Facilitate Knowledge Sharing (2001)

In order to facilitate knowledge sharing in military command centers, the Command 21 research program has created a large shared display – a “Knowledge Wall ” (KW) – that brings together mission relevant information on a shared display. An initial KW prototype was implemented for senior staff during the Global 2000 War Game. In order to assess how well this prototype performed, a usage, utility, and usability evaluation of the KW was performed as it was employed at Global 2000. Data was collected in a minimally-invasive fashion. It included informal observations of KW user behaviors and comments. Further, data was collected automatically by the KW application software. The results of the evaluation suggested that the initial KW prototype adequately supported most of the 14 user requirements identified in a previous cognitive task analysis (Smallman, Oonk &amp; Moore, 2001) and that users preferred it to other that was made available to them in the past. The information products provided the KW users with an integrated summary of the operational picture and allowed them to navigate through the knowledge web to get more detailed information. However, several issues were identified, including those related to usability of the KW and providing cognitive support to users, which need be addressed by in future KW designs. 1.
