NOVEL TUNABLE GaAs MESFET OTA-C INTEGRATORS SUITABLE FOR HIGH PRECEION FILTERING APPLICATIONS (1992)

This paper describes novel single-ended and fully balanced differential input OTA-C integrators with independent control of transconductance (Gm) and output conductance (Go). Since a second order section with separate control of centre frequency and Q can be constructed using just two such units, the circuit lends itself particularly to precision filtering applications.
Digital Image Correlation: From Displacement Measurement to Identification of Elastic Properties - A Review (2005)

The current development of digital image correlation, whose displacement uncertainty is well below the pixel value, enables one to better characterise the behaviour of materials and the response of structures to external loads. A general presentation of the extraction of displacement fields from the knowledge of pictures taken at different instants of an experiment is given. Different strategies can be followed to achieve a sub-pixel uncertainty. From these measurements, new identification procedures are devised making use of full-field measures. A priori or a posteriori routes can be followed. They are illustrated on the analysis of a Brazilian test.
Detection of periods of food intake using Support Vector Machines (2010)

Studies of obesity and eating disorders need objective tools of Monitoring of Ingestive Behavior (MIB) that can detect and characterize food intake. In this paper we describe detection of food intake by a Support Vector Machine classifier trained on time history of chews and swallows. The training was performed on data collected from 18 subjects in 72 experiments involving eating and other activities (for example, talking). The highest accuracy of detecting food intake (94%) was achieved in configuration where both chews and swallows were used as predictors. Using only swallowing as a predictor resulted in 80% accuracy. Experimental results suggest that these two predictors may be used for differentiation between periods of resting and food intake with a resolution of 30 seconds. Proposed methods may be utilized for development of an accurate, inexpensive, and non-intrusive methodology to objectively monitor food intake in free living conditions.
A Reduced Order Turbo-Charging Model for Real Time Engine Torque Profile Control (2015)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Torque profile control is one of required technologies for propulsion engines. A smaller parametric model is more preferable for control algorithm design and evaluation. Mean value engine torque can be obtained from throttle opening change using a transfer function. A transfer function for a turbocharged engine was investigated with thermo-dynamic equations for a turbine and a compressor and test data.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;A small turbocharged engine was tested to model the air transfer process. Turbine speed was measured with temperatures, pressures and air mass flow. Turbine speed response is like a first order system to air mass flow into a combustion chamber. The pressure ratio at the compressor is approximated by a curve proportional to the turbine speed square.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;Based on those findings, a reduced order model for describing dynamic air transfer process with a turbocharger was constructed. The proposed model is compact and suitable for engine torque control design and controller implementation.&lt;/div&gt;&lt;/div&gt;
A decade of magnetic vestibular stimulation: from serendipity to physics to the clinic (2019)

For many years, people working near strong static magnetic fields of magnetic resonance imaging (MRI) machines have reported dizziness and sensations of vertigo. The discovery a decade ago that a sustained nystagmus can be observed in all humans with an intact labyrinth inside MRI machines led to a possible mechanism: a Lorentz force occurring in the labyrinth from the interactions of normal inner ear ionic currents and the strong static magnetic fields of the MRI machine. Inside an MRI, the Lorentz force acts to induce a constant deflection of the semicircular canal cupula of the superior and lateral semicircular canals. This inner ear stimulation creates a sensation of rotation, and a constant horizontal/torsional nystagmus that can only be observed when visual fixation is removed. Over time, the brain adapts to both the perception of rotation and the nystagmus, with the perception usually diminishing over a few minutes, and the nystagmus persisting at a reduced level for hours. This observation has led to discoveries about how the central vestibular mechanisms adapt to a constant vestibular asymmetry and is a useful model of set-point adaptation or how homeostasis is maintained in response to changes in the internal milieu or the external environment. We review what is known about the effects of stimulation of the vestibular system with high-strength magnetic fields and how the understanding of the mechanism has been refined since it was first proposed. We suggest future ways that magnetic vestibular stimulation might be used to understand vestibular disease and how it might be treated.
Mid-infrared supercontinuum generation in chalcogenide multi-step index fibers with normal chromatic dispersion (2017)

We experimentally demonstrate mid-infrared supercontinuum (SC) generation in chalcogenide multi-step index fibers (MSIF) pumped by a femtosecond laser. The fabricated chalcogenide MSIF is composed of a high refractive index core (C1) in the center, which is enclosed by a lower refractive index core layer (C2) and an outer cladding. This fiber structure is advantageous to tailor the chromatic dispersion with higher freedom and to keep the effective mode area small at long wavelengths. The high refractive index core, low refractive index core, and the outer cladding materials are As<sub>2</sub>Se<sub>3</sub>, AsSe<sub>2</sub> and As<sub>2</sub>S<sub>5</sub>, respectively. When the diameter of C1 and C2 are 7.8 and 30 &mu;m, respectively, the zerodispersion wavelength (ZDW) of the fiber is 12.5 &mu;m. The chromatic dispersion profile is near-zero and flattened within the range of &plusmn;20 ps/km/nm in the wavelength range from 4 to 17 &mu;m and a broad normal dispersion region is obtained in the wavelength range shorter than the ZDW. In practice, a 2.8 cm long fiber is pumped at 10 &mu;m by using a femtosecond laser whose pulse width is ~200 fs. The SC generation extending from 2 to 14 &mu;m is obtained. Most of its spectrum is in the normal dispersion region of the fiber. These results are promising for the highly coherent mid-infrared SC generation.
Bis(4-hydroxy-<i>N</i>-isopropyl-<i>N</i>-methyltryptammonium) fumarate: a new crystalline form of miprocin (2020)

The title compound, bis-(4-hy-droxy-<i>N</i>-isopropyl-<i>N</i>-methyl-tryptammonium) (4-HO-MiPT) fumarate (systematic name: bis-{[2-(4-hy-droxy-1<i>H</i>-indol-3-yl)eth-yl](meth-yl)propan-2-yl-aza-nium} but-2-enedioate), 2C<sub>14</sub>H<sub>21</sub>N<sub>2</sub>O<sup>+</sup>·C<sub>4</sub>H<sub>2</sub>O<sub>4</sub> <sup>2-</sup>, has a singly protonated tryptammonium cation and one half of a fumarate dianion in the asymmetric unit. The tryptammonium and fumarate ions are held together in one-dimensional chains by N-H⋯O and O-H⋯O hydrogen bonds. These chains are a combination of <i>R</i> <sub>4</sub> <sup>2</sup>(20) rings, and <i>C</i> <sub>2</sub> <sup>2</sup>(15) and <i>C</i> <sub>4</sub> <sup>4</sup>(30) parallel chains along (110). They are further consolidated by N-H⋯π inter-actions. There are two two-component types of disorder impacting the tryptammonium fragment with a 0.753 (7):0.247 (7) occupancy ratio and one of the fumarate oxygen atoms with a 0.73 (8):0.27 (8) ratio.
Altered Sites of Tyrosine Phosphorylation in pp60 <sup> c- <i>src</i> </sup> Associated with Polyomavirus Middle Tumor Antigen (1986)

We characterized the tyrosine phosphorylation sites of free pp60c-src and of pp60c-src associated with the polyomavirus middle tumor antigen (mT) in transformed avian and rodent cells. The sites of tyrosine phosphorylation in the two populations of pp60c-src were different, both in vitro and in vivo. Free pp60c-src was phosphorylated in vitro at a single site, tyrosine 416. pp60c-src associated with mT was phosphorylated in vitro on tyrosine 416 and on one or more additional tyrosine residues located in the amino-terminal region of the molecule. Free pp60c-src in polyomavirus mT-transformed cells was phosphorylated in vivo on tyrosine 527. In contrast, pp60c-src associated with mT was phosphorylated in vivo on tyrosine 416 and not detectably on tyrosine 527. Thus, the in vivo phosphorylation sites of pp60c-src associated with mT in transformed cells are identical to those of pp60v-src, the Rous sarcoma virus transforming protein. The results suggest that altered phosphorylation of pp60c-src associated with mT may play a role in the enhancement of the pp60c-src protein kinase activity and in cell transformation by polyomavirus.
Question &amp; answering system based on retrieval (2023)

The principle of the question and answering system is nowadays one big branch of natural language processing. When a user enters a query, the system should find the question that is most similar to the entered question stored in the datasets. Then directly return the answer corresponding to the found question. Two models are implemented to better calculate the similarity between entered questions and questions in the corpus: TF-IDF and Word2Vec. After one hundred experiments to test the accuracy of these two models, the result shows that the Word2Vec has 81% accuracy and TF-IDF has only 49% accuracy. It is concluded that Word2Vec has a better accurate performance than TF-IDF. There is also an optimized storage method by using the inverted list for the corpus to improve the models efficiency.
Identification for control: L/sub 2/ and L/sub ∞/ methods (2003)

Identification of restricted-complexity models for linear time-invariant systems is considered. A method, with ties to model reduction and the extended instrumental variable method, is presented, which uses a cost function based on cross-correlations between the prediction error and some auxiliary variable, such as the input. In open loop and under linear feedback, this method is able to asymptotically approximate the underlying system in L/sub 2/ or L/sub /spl infin// norm without an explicit noise model under noisy conditions. Arbitrary frequency weighting, also depending on the true frequency function, can be used. The method is applied to the identification of models that are suited for control design. It is shown that some model-free methods can be fit into this framework. It is also pointed out that closed-loop stability is not taken into account in the bias tuning due to the fact that L-norms are used.
Umbilical vein blood flow measurement in nonimmune hydrops fetalis. (1988)

Twenty-five measurements of fetal umbilical vein blood flow were performed in 22 cases of nonimmune hydrops fetalis using real-time and pulsed Doppler duplex ultrasound. The umbilical vein diameter, blood velocity, and blood flow in fetuses with hemoglobin Bart's hydrops fetalis were usually higher than those in fetuses with hydrops fetalis from other causes. Umbilical vein blood flow measurement appears to be an effective technique for differentiating hemoglobin Bart's from non-Bart's hydrops in this series. This hemodynamic characteristic of umbilical vein blood flow may be helpful in determining the etiology of nonimmune hydrops fetalis.
L'identité diasporique de Claude McKay : la découverte désenchantée du progrès (2015)

This master’s dissertation tackles the issue of Jamaican author Claude McKay’s identity. Oftentimes described as an archetypal author of the Harlem Renaissance or as Jamaica’s national poet, his representations are often incomplete. Taking into account all of McKay’s writings and his travels, we offer a definition of his identity as a diasporic one. Always evolving and reshaping itself, this identity create tension in McKay’s productions. Through his travels and his meetings with fellow artists and thinkers, the author engages himself in an always-frustrated quest for belonging. Modern condition disenchants his discovery of progress.
The Stereospecific Triacylglycerol Structures and Fatty Acid Profiles of Human Milk and Infant Formulas (2006)

We found that most of the examined infant formulas, both preterm and term as well as special formulas, had stereospecific structures and fatty acid profiles that differed considerably from that of human milk.
Bilingual legal document retrieval and management using XML (2002)

Abstract In certain bilingual and multi‐lingual societies, translated legal documents are as important as the original legal documents because they have the same legal status as the originals. However, there is little reported work on the retrieval and management of bilingual legal documents. We describe the design and development of a bilingual document retrieval and management prototype, called ELDoS, which is used by court interpreters and judges from the Hong Kong Judiciary. Since the speed of retrieval is a major concern for user acceptance, and therefore for widespread deployment of the system, the architecture of the prototype is designed to balance the workload of the client and server. Extensible Markup Language (XML) is used to mark up the bilingual legal documents for a variety of document retrieval and management tasks. XML enables the use of XML Stylesheet Language Transformation (XSLT) to align bilingual data in the client, instead of the server, and improve alignment speed linearly with respect to the size of the document, using a high‐end PC, when the server has no concurrent access. The design of the interface was continually improved after extensive consultation with court interpreters and after the user acceptance tests. In our evaluation, the facilities for highlighting translated terms have a macro‐averaged precision of 90+% and a macro‐average recall of 80+%, which were considered acceptable by our users. We believe that the experience in the design and development of this prototype is applicable to other language pairs as well as to other domains. Copyright © 2002 John Wiley &amp; Sons, Ltd.
Evaluation of Booth's algorithm for implementation in parallel multipliers (2002)

The Booth (1951) encoding technique, used in parallel multipliers seems to be obsolete because of the improvement of compression trees using 4:2 compressors. This article compares the two techniques in the case of different lengths of multipliers, and it appears that the reduction bit with 4:2 compressors allows a higher speed and a highly regular layout since the schematic is simple and repetitive.
Efficient primary culture model of patient‑derived tumor cells from colorectal cancer using a Rho‑associated protein kinase inhibitor and feeder cells (2019)

In vitro culture of patient‑derived tumor cells offers many advantages in the development of novel therapies for colorectal cancer. Although various culture systems have been developed, the long‑term expansion of patient‑derived tumor cells remains challenging. The present results suggested that tumor cells isolated from colorectal cancer patient‑derived xenografts can be efficiently immortalized in conditioned medium from irradiated feeder cells containing Y‑27632, a rho‑associated coiled‑coil containing protein kinase (ROCK) inhibitor. Patient‑derived tumor cells proliferated rapidly, reaching 90‑95% confluence in ~6 days. Short tandem repeat analysis suggested that these tumor tissues and cultured cells presented 13 identical short tandem repeat loci, including Amelogenin, Penta E, Penta D, D2S1338 and D19S433. Their epithelial phenotype was confirmed by staining for epithelial cell adhesion molecule and cytokeratin 20, whereas vimentin was used as a mesenchymal marker. When cells were transferred to 3D cultures, they continued to proliferate, forming well‑defined tumor spheroids. Expression levels of human telomerase reverse transcriptase and C‑Myc mRNA were increased in cultured cells. Finally, immortalized cells were used for the screening of 65 anticancer drugs approved by the Food and Drug Administration, allowing the identification of gene‑drug associations. In the present study, primary culture models of colorectal cancer were efficiently established using a ROCK inhibitor and feeder cells, and this approach could be used for personalized treatment strategies for patients with colorectal cancer.
The tryptophan catabolite or kynurenine pathway in Alzheimer’s disease: a systematic review and meta-analysis (2022)

Abstract Background Alzheimer’s disease (AD), characterized by gradual brain dysfunction and memory loss, is one of the major elderly health issues worldwide. Neuroinflammation and increased oxidative stress contribute to the pathophysiology of AD, thereby presumably inducing tryptophan (TRP) degradation through the TRP catabolite (TRYCAT) pathway. Objectives To delineate the activity of the TRYCAT pathway along with levels of TRP and tryptophan catabolites (TRYCATs) in AD patients. Methods We employed PubMed, Google Scholar, Web of Science, and SciFinder to obtain the relevant articles through a search process lasting the entire February 2022. We found 19 eligible articles which involved 738 patients and 665 healthy controls. Results Our result revealed a significant difference ( p = 0.008) in the kynurenine (KYN)/TRP ratio (standardized mean difference, SMD = 0.216, 95% confidence interval, CI: 0.057; 0.376), and a significant decrease in TRP in AD patients (SMD = -0.520, 95% CI: -0.738; -0.302, p &lt; 0.0001). Moreover, we also found a significant increase in the central nervous system (CNS, brain and cerebrospinal fluid, CSF) kynurenic acid (KA)/KYN ratio but not in peripheral blood, as well as a significant decrease in plasma KA and xanthurenic acid (XA) in the CNS and blood. Conclusions AD is characterized by TRP depletion but not by an overactivity of the TRYCAT pathway. IDO-induced production of neurotoxic TRYCATs is not a key factor in the pathophysiology of AD.
Molecular Beacon Imaging System to Discriminate the Differentiation State of Cells from Energy Metabolic Pathways (2023)

Metabolic pathways of energy production play an essential role as a function of cells. It is well recognized that the differentiation state of stem cells is highly associated with their metabolic profile. Therefore, visualization of the energy metabolic pathway makes it possible to discriminate the differentiation state of cells and predict the cell potential for reprogramming and differentiation. However, at present, it is technically difficult to directly assess the metabolic profile of individual living cells. In this study, we developed an imaging system of cationized gelatin nanospheres (cGNS) incorporating molecular beacons (MB) (cGNS<sub>MB</sub>) to detect intracellular pyruvate dehydrogenase kinase 1 (PDK1) and peroxisome proliferator-activated receptor γ, coactivator-1α (PGC-1α) mRNA of key regulators in the energy metabolism. The prepared cGNS<sub>MB</sub> was readily internalized into mouse embryonic stem cells, while their pluripotency was maintained. The high level of glycolysis in the undifferentiated state, the increased oxidative phosphorylation over the spontaneous early differentiation, and the lineage-specific neural differentiation were visualized based on the MB fluorescence. The fluorescence intensity corresponded well to the change of extracellular acidification rate and the oxygen consumption rate of representative metabolic indicators. These findings indicate that the cGNS<sub>MB</sub> imaging system is a promising tool to visually discriminate the differentiation state of cells from energy metabolic pathways.
COACH: A context aware and multi-service trust model for Cooperation management in heterogeneous wireless networks (2013)

The wide majority of existing trust-based systems in wireless networks are today bound to a single service. As such, they cannot use past experiences related to other services. Even those that support multiple services hide this heterogeneity by regrouping all past experiences and contexts into a single metric, which strongly degrades the quality of results. To go beyond these restrictions, we designed a novel context-aware and multi-service trust model for heterogeneous wireless networks that involve nodes with different resources capabilities. Simulation results prove the proper functioning of the proposed system and its effectiveness against common attacks hindering trust models.
First-Principle Study on Correlate Structural, Electronic and Optical Properties of Ce-Doped BaTiO3 (2023)

The structural, electronic, and optical properties of pure and Ce-doped BaTiO3 were investigated based on first-principle calculation. Here, we concentrate on understanding the effect of the substitution of Ce for Ba and Ti sites in the equilibrium lattice parameters, DOS, electronic band structure, and optical performance of the materials. The crystal structures with a 12.5% doping ratio at different sites were constructed by superseding an atom of Ba (or Ti) site with a Ce atom and investigating the optimized crystal structure parameters. The substitution of Ce leads to a reduction in the band gap by inducing the movement of the conduction band minimum (CBM) and valence band maximum (VBM). The reduction in the band gap has been shown to be beneficial in increasing electrical conductivity. The density of states of the materials was calculated to gain insight into the valence band, conduction band, and contribution of each orbital to the total density of states in the electronic structure. The charge density, Mulliken charges, and bond overlap populations of pristine and Ce-doped BaTiO3 were calculated to understand the nature of chemical bonds before and after doping. In addition, the optical properties of the materials were calculated, and the substitution of Ce for Ba site increased the static dielectric constant. In contrast, it decreased when Ce was doped into the Ti site. The substitution of Ce for different sites reduced the reflectivity of the material, while the transparency of the materials before and after doping was almost the same. The materials were transparent to incident light when the photon energy was below 10 eV, whereas opacity was in the ultraviolet range of 10–13 eV and beyond 20 eV. The theoretical calculation of different properties provides a new idea for the theoretical study of the BaTiO3-based system.
Predictors of Post‐operative Pain and Opioid Consumption in Patients Undergoing Liver Surgery (2019)

Younger patients and those with a history of analgesic use are more likely to report higher post-operative pain and require higher doses of opioids. Early identification of these patients, and measures to better manage their pain, may contribute to optimal perioperative care.
Intensity Analysis of Recurrence Plots for the Detection of Deterministic Signals in Noise (2006)

Abstract : This report describes a new method for the detection of deterministic signals in the presence of additive white Gaussian noise. The new method, based on recurrence plots, relies on a sliding-window technique combined with histogram analysis. Performance of the new approach is quantified in terms of receiver-operator characteristic (ROC) curves. The report also provides background information on recurrence plots and ROC curves necessary to understand the new approach.
