13C and 15N abundance of plasma and saliva protein reflect protein intake from vegetable and animal products (2008)

Self‐reported dietary intake is often biased. Therefore there is a need for objective biomarkers of diet. We investigated whether isotopic compositions of human protein reflected the proportion of plant and animal protein intake of individuals consuming U.S. foods. We recruited nine each omnivore, lacto‐ova vegetarian, and strict vegan healthy adults. Food frequency questionnaires were administered to assess protein intake. Plasma and saliva protein specimens were analyzed using an isotope ratio mass spectrometry equipped with an elemental analyzer. For plasma protein samples, vegans could be distinguished from omnivores in both 13 C (−21.6‰ ± 0.5 vs. −19.3‰ ± 0.5, p &lt; 0. 01) and 15 N (8.0‰ ± 0.5 vs. 9.0‰ ± 0.3, p &lt; 0.01) abundances. Lacto‐ova vegetarians were significantly different from vegans for both 13 C and 15 N abundances. For saliva protein, vegans could be clearly distinguished from omnivores in 13 C (−21.5‰ ± 0.6 vs. −19.6‰ ± 0.7, p &lt; 0. 01) and trended in 15 N (6.6‰ ± 0.7 vs. 7.3‰ ± 0.7, p = 0.02). The 13 C abundances of omnivores were close to values predicted for US foods, but values for vegans contained more 13 C than predicted suggesting carbon exchange between macronutrients via intermediary metabolic pathways. The 15 N differences displayed the expected trophic level effect. In conclusion, human plasma and saliva 13 C and 15 N values both reflected the proportion of animal protein in the U.S. diet.

Part 7. Effects of poly(L‐lactide‐co‐ϵ‐caprolactone) on morphology, structure, crystallization, and physical properties of blends of poly(L‐lactide) and poly(ϵ‐caprolactone) (2003)

Abstract Blended films of poly( L ‐lactide) [ie poly( L ‐lactic acid)] (PLLA) and poly(ϵ‐caprolactone) (PCL) without or mixed with 10 wt% poly( L ‐lactide‐ co ‐ϵ‐caprolactone) (PLLA‐CL) were prepared by solution‐casting. The effects of PLLA‐CL on the morphology, phase structure, crystallization, and mechanical properties of films have been investigated using polarization optical microscopy, scanning electron microscopy, differential scanning calorimetry and tensile testing. Addition of PLLA‐CL decreased number densities of spherulites in PLLA and PCL films, and improved the observability of spherulites and the smoothness of cross‐section of the PLLA/PCL blend film. The melting temperatures ( T m ) of PLLA and PCL in the films remained unchanged upon addition of PLLA‐CL, while the crystallinities of PLLA and PCL increased at PLLA contents [ X PLLA = weight of PLLA/(weight of PLLA and PCL)] of 0.4–0.7 and at most of the X PLLA values, respectively. The addition of PLLA‐CL improved the tensile strength and the Young modulus of the films at X PLLA of 0.5–0.8 and of 0–0.1 and 0.5–0.8, respectively, and the elongation at break of the films at all the X PLLA values. These findings strongly suggest that PLLA‐CL was miscible with PLLA and PCL, and that the dissolved PLLA‐CL in PLLA‐rich and PCL‐rich phases increased the compatibility between these two phases. © 2003 Society of Chemical Industry
Thermal degradation of polyurethanes investigated by direct pyrolysis in the mass spectrometer (1980)

Abstract Direct pyrolysis in the mass spectrometer yielded evidence on the mechanisms of thermal decomposition of N ‐monosubstituted and N ‐disubstituted polyurethanes. Our results indicate that N ‐monosubstituted polyurethanes undergo quantitatively a depolycondensation process, producing diisocyanate and diol. In contrast, disubstituted polyurethanes decompose to give selectively secondary amine, olefine and CO 2 .

Experimental validation of time optimal MPC on a flexible motion system (2011)

This paper discusses the application and experimental validation of time-optimal model predictive control (TOMPC) on a flexible motion system, an overhead crane with fixed cable length. TOMPC realizes minimal settling times for point-to-point motions taking into account system constraints. Results of several different point-to-point motion experiments and of disturbance rejection experiments clearly demonstrate this time optimal behavior. The extension of the TOMPC algorithm to increase its feasibility range required for large point-to-point motions is discussed and validated.

Globally Convergent Numerical Methods for Coefficient Inverse Problems for Imaging Inhomogeneities (2010)

How can we differentiate between an underground stone and a landmine? A class of new numerical methods aims to address this question using globally convergent-rather than locally convergent-algorithms for coefficient inverse problems. Numerical results model imaging of the spatially distributed dielectric permittivity function in an environment where antipersonnel landmines are embedded along with stones.
Influence of intermediate layers on thick InGaN growth using tri-halide vapor phase epitaxy (2019)

Abstract A thick and fully relaxed In 0.05 Ga 0.95 N layer was epitaxially grown on a GaN substrate after growing partially relaxed intermediate InGaN layers using tri-halide vapor phase epitaxy. In order to control the relaxation ratio of intermediate InGaN layers, a double intermediate structure with different growth rates (low growth rate and high growth rate modes) was adopted. By changing the first intermediate InGaN layer thickness, the relaxation ratio could be varied in the ranges between 25% and 59%. According to X-ray diffraction reciprocal space mapping measurements, a fully relaxed In 0.05 Ga 0.95 N layer was successfully grown on a partially relaxed intermediate In 0.10 Ga 0.90 N layer with the relaxation ratio of 32%. Thus, a mirror-like, fully relaxed and thick In 0.05 Ga 0.95 N layer could be grown with lattice matched to the intermediate InGaN layers by controlling the relaxation ratio.
Process and Temperature Compensation in a 7-MHz CMOS Clock Oscillator (2006)

This paper reports on the design and characterization of a process, temperature and supply compensation technique for a 7-MHz clock oscillator in a 0.25-/spl mu/m, two-poly five-metal (2P5M) CMOS process. Measurements made across a temperature range of -40/spl deg/C to 125/spl deg/C and 94 samples collected over four fabrication runs indicate a worst case combined variation of /spl plusmn/2.6% (with process, temperature and supply). No trimming was performed on any of these samples. The oscillation frequencies of 95% of the samples were found to fall within /spl plusmn/0.5% of the mean frequency and the standard deviation was 9.3 kHz. The variation of frequency with power supply was /spl plusmn/0.31% for a supply voltage range of 2.4-2.75 V. The clock generator is based on a three-stage differential ring oscillator. The variation of the frequency of the oscillator with temperature and process has been discussed and an adaptive biasing scheme incorporating a unique combination of a process corner sensing scheme and a temperature compensating network is developed. The biasing circuit changes the control voltage of the differential ring oscillator to maintain a constant frequency. A comparator included at the output stage ensures rail-to-rail swing. The oscillator is intended to serve as a start-up clock for micro-controller applications.
Direct grid connection of matrix converter with transition control for flywheel UPS (2012)

This paper discusses an uninterrupted power supply (UPS) with a flywheel and a matrix converter using a direct grid connection. A flywheel type UPS has a problem where a standby power is bigger than that of the battery or EDLC type UPS. To solve this problem, an operation known as direct grid connection mode is proposed, where a matrix converter is the interface converter between the flywheel and grid. In the direct grid connection mode, the matrix converter has no switching operation. Thus, the converter loss is remarkably low in the standby mode due to no switching loss. However, a rush output current will occur in when the matrix converter is transited from PWM to direct grid connection mode. In order to solve this problem, in this paper, a transition control which treats the output voltage to correspond to the input voltage is proposed. Additionally, the validity of the proposed control is demonstrated in the simulation and experimental results.
Classification of users’ transportation modalities from mobiles in real operating conditions (2021)

The modern mobile phones and the complete digitalization of the public and private transport networks have allowed to access useful information to understand the user's mean of transportation. This enables a plethora of old and new applications in the fields of sustainable mobility, smart transportation, assistance, and e-health. The precise understanding of the travel means is at the basis of the development of a large range of applications. In this paper, a number of metrics has been identified to understand whether an individual on the move is stationary, walking, on a motorized private or public transport, with the aim of delivering to city users personalized assistance messages for: sustainable mobility, health, and/or for a better and enjoyable life, etc. Differently from the state-of-the-art solutions, the proposed approach has been designed to provide results, and thus collect metrics, in <i>real operating conditions</i> (imposed on the mobile phones as: a range of different mobile phone kinds, operating system constraints managing Applications, active battery consumption manager, etc.). The paper reports the whole experimentations and results. The solution has been developed in the context of Sii-Mobility Km4City Research Project infrastructure and tools, performed with the collaboration of public transport operators, and GDPR compliant. The same solution has been used in Snap4City mobile Apps with experiments performed in Antwerp and Helsinki.
Functional role of Zic2 phosphorylation in transcriptional regulation (2007)

Zic2 is a transcriptional activator that plays a crucial role in mammalian forebrain development. It activates the transcription of target genes by DNA binding and recruitment of RNA helicase A (RHA). We recently reported that the Zic2-RHA interaction is decreased by phosphatase treatment in vitro. We have now identified the phosphorylation site (serine 200) in mouse Zic2. Zic2S200A was defective in RHA-binding, and its transcriptional activation ability was diminished. These data indicate that Zic2S200 is a target for phosphorylation by DNA-dependent protein kinase, regulating Zic2-mediated transcriptional activation.

Comparison of Content in Phenolic Compounds, Polyphenol Oxidase, and Peroxidase in Grains of Fifty Sorghum Varieties from Burkina Faso (2002)

Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina Faso showed that they have different contents of phenolic compounds, peroxidase (POX), and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than 0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenolase specific activities of PPO. For POX, there was a diversity of isoforms among varieties. No clear correlation could be made between the quantitative composition of the grain in phenolics, PPO, and POX, and resistance of plant to pathogens. In general, varieties good for a thick porridge preparation ("tô") had low phenolic compounds content and a medium POX activity. From the red varieties, those used for local beer ("dolo") had a high content in phenolic compounds and PPO, and a low POX activity. The variety considered good for couscous had a low POX content. The characteristics might be useful as selection markers for breeding for specific applications.
Transient Viscoelastic Flow Simulation of Film Blowing Process Incorporating Crystallization Model (2022)

An analysis model for the transient viscoelastic flow in the film blowing process was newly developed based on the Galerkin finite element method and incorporating the cooling and crystallization behaviors. Assuming that physical quantities such as temperature and stress are constant in the thickness direction, the process was approximated to be one dimensional in the axisymmetric coordinate system, and the Lagrangian analysis, which involves remeshing and rezoning, was performed. In calculating the air pressure difference, constant air mass in the bubble was assumed and the effect of opening angle of the guide rolls, which lead the blown bubble to the pinch roll, was investigated. The viscoelastic properties were expressed by the multi-mode PTT model. Regarding crystallization characteristics, a phenomenological crystallization model developed by us was used. The model was based on the non-isothermal crystallization characteristics evaluated using a high-speed DSC. Four types of polyethylene, i.e. two LLDPEs, a blend of LLDPE and LDPE, and HDPE, were used and a comparative study of experimental results and results of model analyses for the film blowing process was carried out. Guidelines for appropriate input parameter settings such as the negligibility of the parameter for orientation induced crystallization and the necessity of adopting the heat transfer coefficient functions were obtained. By reflecting these findings in the simulation, the experimental results of polyethylene film blowing, including the unstable film formation behavior, could be predicted well by the developed model.
Dancing Quadrocopters: Trajectory Generation, Feasibility, and User Interface (2011)

This Master Thesis presents various tools that enable the generation of quadrocopter choreograpies for the Flying Machine Arena.The goal of this thesis was to facilitate the design of multi-vehicle choreographies through the developement of a graphical user interface.The resulting software allows the user to easily define trajectories for the quadrocopters.In addition, the feasibility of a choreography can be assessed using the program.In the first part of this work, we provide the mathematical foundation of the developed methods: Different motion primitives are introduced and their trajectories are defined.A method that determines the feasibility of arbitrary trajectories is demonstrated.Then, an algorithm that exploits convex optimization in order to plan collision-free trajectories for multiple quadrocopters is described.In the second part of this work, we introduce the software tool which was developed as a part of this thesis.v
Influence of free fatty acids on oxidative stability in water‐in‐walnut oil emulsions (2013)

The effect of free fatty acids (FFA) on lipid oxidation in water‐in‐stripped walnut oil emulsions was investigated. The formation of the primary oxidation products (hydroperoxides) and the secondary oxidation product (headspace hexanal) increased with increasing addition of oleic acid to the emulsions. However, oleic acid at high concentrations was primarily involved in accelerating hydroperoxide formation at early stage and then hydroperoxide decomposition rapidly after hydroperoxides reached the maximum point. The prooxidant effect of saturated FFA was dependent on their chain length with lipid oxidation rates being in the order of lauric acid&gt;palmitic acid&gt;stearic acid. The highest prooxidant activity of lauric acid among these FFA was probably due to its largest polarity and making the water droplet interface more negatively charged than the others when the aqueous phase pH was 7.0, which was above its p K a , thereby attracting prooxidant metals to the water droplet surface. The highest ability to promote lipid oxidation in water‐in‐oil emulsions was shown by linolenic acid, followed by linoleic and oleic acids, indicating that the oxidative capacity increased with increasing degree of unsaturation. The prooxidant effect of FFA with the cis double bonds was lower than those with the trans ones when oleic acid (18:1, cis ) was compared to elaidic acid (18:1, trans ) and linoleic acid (18:2, cis – cis ) was compared to linoelaidic acid (18:2, trans – trans ), which suggested that geometric isomeration of FFA influenced lipid oxidation rates of water‐in‐oil emulsions. Practical applications: FFA promote lipid oxidation in bulk oil and oil‐in‐water (O/W) emulsions. From the present study, it became clear that FFA were also strong prooxidants in water‐in‐oil (W/O) emulsions. This research pointed out the importance of using oils and fats containing minimal FFA in W/O emulsion formulation to obtain the highest quality.

Spectral Characteristics of Citrus Black Spot Disease (2016)

Citrus black spot (CBS) is a fungal disease caused by Phyllosticta citricarpa (synonym Guignardia citricarpa ). CBS causes fruit lesions and significant yield loss in all citrus ( Citrus ) species. The most distinguishing CBS symptom is called hard spot, which is a circular lesion with gray tissue at the center surrounded by a black margin. The spectral characteristic of CBS lesions was investigated and compared with the spectral signature of healthy fruit tissue to determine the best distinguishing wave band. Healthy and CBS-affected samples presented similar reflectance below 500 nm and above 900 nm. However, healthy samples reflected more light between 500 and 900 nm, especially within the visible band. Also, spectral reflectance of the same symptomatic lesion was acquired six times over a 2-month period to determine the variation of symptom’s spectral signatures over time after being harvested. A two-sample t test was employed to compare each pair of consecutive repetitions. The results showed that the spectral signature of the CBS lesion did not change significantly over 2 months. The wavelengths between 587 and 589 nm were identified as the distinguishing band to develop a monochrome vision–based sensor for CBS diagnosis. A support vector machine (SVM) classifier was trained using the spectral reflectance data at the selected bands to identify CBS-affected samples in each repetition. The overall CBS detection accuracies varied between 93.3% and 94.6%.
Reaction of organoboranes with neutral hydrogen peroxide (1970)

Tri-n-hexylborane reacts vigorously with neutral aqueous hydrogen peroxide with the cleavage of two of the three boron–carbon bonds, to give a mixture of hydrocarbons and n-hexanol. In particular, good yields of dimeric hydrocarbons are formed. When the reaction is performed in carbon tetrachloride solution, the yield of dimer decreases and is replaced by alkyl chlorides and more alcohol. The reaction is applied to other organoboranes.
