Probing mhz processes in 3d with x-ray microscopy

I aim to develop an X-ray imaging technique capable of filming processes in 3D, with a temporal resolution several orders of magnitude faster than up-to-date 3D X-ray imaging techniques.
The unique penetration power of X-rays allows us to study systems in their native environment. This property has led to the development of X-ray microtomography (µCT). µCT acquires 3D information, which determines the functionality and mechanical properties of nature, by rotating a sample with respect to the X-ray source. µCT is a crucial tool for several scientific disciplines such as physics, biology, and chemistry. 
Over the last decade, µCT has become a technique capable of not only recording 3D information but also filming dynamical processes. Several breakthroughs have made this possible: i) intense X-ray sources (synchrotron light sources), ii) efficient and fast X-ray detectors, and iii) fast 3D reconstruction algorithms. Despite all of these developments, the acquisition protocols remain unchanged, i.e., the sample is only rotated faster. This fast rotation introduces forces which may alter the studied dynamics and ultimately limit the achievable temporal resolution.
My project is to establish an X-ray microscope that avoids the sample rotation, obtaining 3D information from a single X-ray flash by splitting it into nine-angularly resolved beams which illuminate the sample simultaneously. This approach, when implemented at intense X-ray sources such as synchrotron light sources and X-ray free-electron lasers, will allow the filming of natural processes with micrometer to nanometer resolution and resolve dynamics from microseconds to femtoseconds. To demonstrate its capabilities, I will study fundamental processes in cellulose fibers, a renewable biomaterial, which can replace fossil-based materials, such as plastics. This technique will open up the possibility to film dynamics in 3D to answer questions coming from industry and natural sciences at rates not accessible today.
Wafers for automotive and other key applications using memories, embedded in ulsi processors

The WAKEMEUP project objective is to set-up a pilot line for advanced microcontrollers with embedded non-volatile memory, design and manufacturing for the prototyping of innovative applications for the smart mobility and smart society domains.
The already defined microcontrollers with 40nm embedded flash technology will be consolidated to build a solid manufacturing platform. Additional developments will be performed for the integration of memory, power management, connectivity, hard security on the same chip.
The project will also target the industrialization of the embedded Phase Change Memory (PCM) technology built on top of the FDSOI 28nm logic process pilot line. The development of the ePCM will be driven by the final application requirements as well as decreasing the power consumption.
The alternative memory solutions will be also studied as they have different - and complementary - traits in such areas as read/write speed, power and energy consumption, retention and endurance, and device density and benchmarked with the ePCM and the conventional eFlash. Continued advances in materials, device physics, architectures and design could further reduce the energy consumption of these memories.
To achieve this goal of generating high value added semiconductor circuits in Europe in a breakthrough leading edge technology the project will deploy all the necessary activities to bring a new technology to an early industrial maturity stage. These activities encompass such developments as: technology enhancements for various specific application requirements such as wide temperature range and reliability, high security requests, high flexibility…, design enablment allowing first time silicon success, prototyping demonstrator products in the different application areas.
In the WAKEMEUP project, new devices and systems will be developed by the application partners in automotive and secure based on FD-SOI and embedded digital technology to answer specific applications needs.
Multibody Simulation of Planetary Rover Mobility in Condition of Uncertain soft Terrain

Abstract Mobility analysis by computer multi-body simulation of wheeled rovers plays a fundamental role in planetary exploration programs. Considering that in space missions systems have to operate within an environment often times largely unknown, it turns out that embedding numerical analyses with stochastic methods can be beneficial. This work presents results from applying nondeterministic methods to mobility analysis of a planetary rover in condition of uncertain terrain properties. The terrain uncertainty is quantified by experimental measurements of the soil properties by a dedicated equipment. Next, the soil uncertainty is propagated through a multi-body model in order to assess the uncertainty of the rover position when traveling on soft soil. Probabilistic and non-probabilistic approaches are carried out and compared.
Clustering gene expression data analysis using an improved EM algorithm based on multivariate elliptical contoured mixture models

Abstract Clustering gene expression data is an important research topic in bioinformatics because knowing which genes act similarly can lead to the discovery of important biological information. Many clustering algorithms have been used in the field of gene clustering. The multivariate Gaussian mixture distribution function was frequently used as the component of the finite mixture model for clustering, however the clustering cannot be restricted to the normal distribution in the real dataset. In order to make the cluster algorithm strong adaptability, this paper proposes a new scheme for clustering gene expression data based on the multivariate elliptical contoured mixture models (MECMMs). To solve the problem of over-reliance on the initialization, we propose an improved expectation maximization (EM) algorithm by adding and deleting initial value for the classical EM algorithm, and the number of clusters can be treated as a known parameter and inferred with the QAIC criterion. The improved EM algorithm based on the MECMMs is tested and compared with some other clustering algorithms, the performance of our clustering algorithm has been extensively compared over several simulated and real gene expression datasets. Our results indicated that improved EM clustering algorithm is superior to the classical EM algorithm and the support vector machines (SVMs) algorithm, and can be widely used for gene clustering.

On the De-Embedding Issue of Millimeter-Wave and Sub-Millimeter-Wave Measurement and Circuit Design

The purpose of this paper is to address the de-embedding issue of millimeter-wave (mmWave) and sub-mmWave measurements and circuit design by extensively comparing several commonly used methods and by proposing a new full-matrix calculation-based de-embedding methodology. The comparison aims to investigate the impacts of different de-embedding methods on mmWave and sub-mmWave circuit design. A new de-embedding method has been proposed to achieve more accurate results on mmWave and sub-mmWave range. In this method, all possible extrinsic elements are subtracted from the measured device under test data by matrix calculation to eliminate the error from equivalent circuit. The influence of parasitic elements on the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">f</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> and <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">f</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MAX</sub> are investigated. The comparison of the different de-embedding methods for transistors are performed up to 170 GHz, the results showed that the proposed method has good accuracy even at very high-frequency and it is suitable for mmWave and sub-mmWave measurements and circuit design.
Enzymatic hydrolysis lignin derived from corn stover as an intrinsic binder for bio-composites manufacture: Effect of fiber moisture content and pressing temperature on boards’ properties

Binderless fiberboards from enzymatic hydrolysis lignin (EHL) and cotton stalk fibers were prepared under various manufacturing conditions, and their physico-mechanical properties were evaluated. Full factorial experimental design was used to assess the effect of fiber moisture content and pressing temperature on boards’ properties. In addition, differential scanning calorimetry (DSC) was used to obtain the glass transition temperature (Tg) of EHL. We found that both fiber moisture content and pressing temperature had significant effects on binderless fiberboards’ properties. High fiber moisture content and pressing temperature are suggested to contribute to the self-bonding improvement among fibers with lignin-rich surface mainly by thermal softening enzymatic hydrolysis lignin. In this experiment, the optimized pressing temperature applied in binderless fiberboard production should be as high as 190°C in accordance with the EHL Tg value of 189.4°C, and the fiber moisture content should be limited to less than 20% with a higher board density of 950 kg/m3 to avoid the delamination of boards during hot pressing.
Identification and characterization of quantitative trait loci for grain yield and its components under different nitrogen fertilization levels in rice (Oryza sativa L.)

A set of rice (Oryza sativa L.) recombinant inbred lines from a cross between Zhenshan 97 (indica) and HR5 (indica) was planted for four different growing seasons in two locations at three nitrogen (N) fertilization levels (N300, 300 kg urea/ha; N150, 150 kg urea/ha; and N0, 0 kg urea/ha). Grain yield and its components were evaluated, including grain yield per plant (GYPP), panicle number per plant (PNPP), grain number per panicle (GNPP), filled grains per panicle (FGPP), spikelet fertility percentage (SFP) and 100-grain weight (HGW). Correlation and path analysis indicated that SFP had the greatest contribution to GYPP at the N300 and N150 levels, but FGPP contributed the most to GYPP at the N0 level. Quantitative trait loci (QTL) were mapped based on a mixed linear model; genetic components (main effects, epistatic effects and QTL-by-environment interactions) were estimated separately. Six to 15 QTL with main effects were detected for each trait except SFP. Clusters of main-effect QTL associated with PNPP, GNPP, SFP and HGW were observed in regions on chromosomes 1, 2, 3, 5, 7 and 10. The main-effect QTL (qGYPP-4b and qGNPP-12) were only detected at the N0 level and explained 10.9 and 10.2% of the total phenotypic variation, respectively. A total of 33 digenic interactions among grain yield and its components were also identified. The identification of genomic regions associated with yield and its components at different nitrogen levels will be useful in marker-assisted selection for improving the nitrogen use efficiency of rice.

Group B Streptococcus Interactions with Human Meningeal Cells and Astrocytes In Vitro

Streptococcus agalactiae (Group B Streptococcus, GBS) is a leading cause of life-threatening neonatal meningitis and survivors often suffer permanent neurological damage. How this organism interacts with the meninges and subsequently with astrocytes that constitute the underlying cortical glia limitans superficialis is not known.In this paper, we demonstrate dose-dependent adherence of GBS over time to human meningioma cells and fetal astrocytes in vitro, which was not influenced by expression of either β-haemolysin/cytolysin (β-h/c) toxin, different capsule serotypes or by absence of capsule (p>0.05). Internalization of GBS by both cell types was, however, a slow and an infrequent event (only 0.02-0.4% of associated bacteria were internalised by 9 h). Expression of β-h/c toxin did not play a role in invasion (p>0.05), whereas capsule expression lead to a reduction (p<0.05) in the numbers of intracellular bacteria recovered. GBS strains induced cytotoxicity as demonstrated by the measurement of lactate dehydrogenase (LDH) enzyme release by 9 h and by viable staining. Increasing levels of meningioma cell death correlated with bacterial growth and the phenotype of β-h/c toxin production, i.e. from weakly, to normo- to hyper-haemolytic. However, cytotoxicity was significantly greater (p<0.05) towards astrocytes, and infection with initial MOI≥0.003 induced 70-100% LDH release. By comparing wild-type (β-h/c(+)) and mutant (ΔcylE β-h/c(-)) strains and β-h/c toxin extracts and by using the surfactant dipalmitoylphosphatidylcholine in cytotoxicity inhibition experiments, β-h/c toxin was demonstrated as principally responsible for cell death.This study has described key events in the interactions of GBS with meningeal cells and astrocytes in vitro and a major virulence role for β-h/c toxin. Understanding the mechanisms involved will help to identify potential therapies for improving patient survival and for reducing the incidence and severity of neurological sequelae.

Survey of cytopathologists and cytotechnologists for the clinical impact of the use of atypia or follicular lesion of undetermined significance

Background: The cytologic diagnosis of atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) is controversial because of variation in how it is applied in practice, as well as uncertainty about patient management. We aimed to assess the percentage of thyroid fine-needle aspiration biopsies (FNABs) with AUS/FLUS diagnoses in different North American and European practice settings (e.g. community, academic, etc.), assess whether patients were managed according to current guidelines, and determine patient outcomes. Materials and Methods: A detailed questionnaire survey was posted in secure websites used separately by cytopathologists and cytotechnologists. The questionnaire was posted from August 1 through December 31, 2013. Results: Endocrinologists and cytopathologists performed 51.7% and 37.1% of thyroid FNABs, respectively. The Bethesda reporting system for thyroid FNAB was used in 90% of practices. The rate of AUS/FLUS varied widely among institutions, with 46.1% of represented institutions reporting AUS/FLUS rates of 3–10%. The median follow-up rate of patients with an initial AUS/FLUS diagnosis was 70% (range, 10–100%). For the majority of represented institutions (86.4%), patients with initial AUS/FLUS diagnosis had follow-up with endocrinologists. Of repeat AUS/FLUS thyroid FNABs, a median of 52% was considered benign, and 18% were suspicious of or positive for malignancy (median, 10% and 7.5%, respectively). Conclusions: Reporting of the AUS/FLUS category varied widely among different institutions. The median follow-up rate was lower than published guidelines. The most common follow-up diagnosis was benign thyroid nodule. Improved standardization of cytologic criteria should be adopted to reduce such variation.
Anatomy of Automatic Mobile Carbon Footprint Calculator

A number of web-based systems provide environmental information to support our ecological lifestyle. However, there exists a need for more accurate and automated online systems facilitating personalised ecological awareness. This paper presents a travel type detection system for an automatic mobile carbon emission calculator. The system is able to detect automatically trips made by mobile users and provide them an easy and quick way for estimating the travel related CO2 emissions. The system is based on energy and computationally effective multisource fusion in a mobile device. The paper introduces the system with design rationale, explains smartphone implementation and provides comprehensive evaluation from both accuracy and energy efficiency points of view. The system attained the overall travel type detection accuracy of 77% and the daily average current consumption of 33mA. The results show great promise for the developed methodology to facilitate 24/7 carbon emission estimation of a traveller.
A statistical study on energy performance of U.S. convenience stores: Investigation of factors and bench marking on store energy use

Abstract Convenience stores are known to have higher Energy Use Intensities (EUIs) than most other commercial building types. However, convenience store energy performance analyses have not been systematically investigated. Moreover, current national convenience store benchmarks are inconsistent from one data base to another due to lack of relevant energy data. This paper assesses the energy performance of more than five hundred convenience stores in the same fleet in Eastern United States. The investigation aims to establish benchmarks for convenience stores with and without gasoline pumping stations. The main factors influencing the actual convenience store building energy use were determined. Multiple regression models were developed to find relationships between annual energy consumption per unit area and gross floor area, customer transaction count, building operating year, etc. The statistically characterized results are meant to serve as a reference data set in comparing the whole-building energy performance index for buildings of similar functionality. The statistical correlation analyses can strengthen the robust prediction of energy performance in convenience stores, enabling proper assessment of energy conservation measurements (ECMs) for convenience store operations, as well as guiding additional such energy performance studies.
[Correlation of follicular fluid human chorionic gonadotrophin level with oocyte maturity and early embryonic development].

To explore the correlation of human chorionic gonadotrophin (hCG) level in the follicular fluid on oocyte retrieval day with the number of oocytes retrieved, maturation rate, embryonic development, and pregnancy outcome in controlled ovarian stimulation cycles.The data of 311 IVF/ICSI-ET cycles from 2012 to 2013 was analyzed and stratified according to hCG level in follicular fluid on oocyte retrieval day (<7 nmol/L, 7-14 nmol/L, 14-21 nmol/L, and >21 nmol/L) determined with chemiluminescence method. The number of oocytes retrieved, oocyte maturation rate, fertilization rate, cleavage rate, available embryo rate and pregnancy rate were compared between the groups.In the IVF/ICSI-ET cycles, the cycles with hCG level of 14-21 nmol/L in the follicular fluid on the day of oocyte retrieval had significantly higher oocyte maturation rate and fertilization rate than those in the other 3 groups (P<0.05), but the number of oocytes retrieved, cleavage rate, available embryo rate and pregnancy rate, though slightly higher, showed no significant difference from the other 3 groups (P>0.05). In the group with hCG level >21 nmol/L, the oocyte maturation rate and fertilization rate were significantly lower than those in the other 3 groups (P<0.05), and the available embryo rate and pregnancy rate were slightly lower without significant differences from the other 3 groups (P<0.05).Follicular fluid hCG level on the day of oocyte retrieval is associated with oocyte maturation, fertilization, embryonic development potential, and IVF outcome. An excessively high follicular fluid hCG level on the day of oocyte retrieval may have negative effects on oocyte maturation and embryo development.
Labor market effects of knowledge spillovers

This paper studies the diffusion of technology that occurs from Multinational Enterprises to domestic firms via worker mobility. It concentrates on the wage and unemployment implications of diffusion of knowledge through labor mobility in the local labor market. We construct a search model where the labor mobility is restricted by the existence of binding contracts. Findings of the model reveal that knowledge spillovers through the movement of workers from foreign to local firm lower the firm premium and the skill premium. Further results indicate that technological progress raising the productivity gap between the foreign and the local firm leads to an increase in the unemployment rate, the firm premium and the skill premium.
