Similarity of the Effects ofErythritol and Xylitol on SomeRisk Factors of Dental Caries (2005)

Several sugar alcohols (polyols) have been promoted as potential sugar substitutes in caries limitation. However, differences in the effects of simple alditol-type sugar alcohol homologues on dental plaque have not been compared in clinical tests. The effects of 6-month use of erythritol (a sugar alcohol of the tetritol type), xylitol (a pentitol) and D-glucitol (sorbitol, a hexitol) were investigated in a cohort of 136 teenage subjects assigned to the respective polyol groups or to an untreated control group (n = 30-36 per group). The daily use of the polyols was 7.0 g in the form of chewable tablets, supplemented by twice-a-day use of a dentifrice containing those polyols. The use of erythritol and xylitol was associated with a statistically significant reduction (p < 0.001 in most cases) in the plaque and saliva levels of mutans streptococci. The amount of dental plaque was also significantly reduced in subjects receiving erythritol and xylitol. Such effects were not observed in other experimental groups. Chemical analyses showed D-glucitol to be a normal finding in dental plaque while xylitol was less consistently detected. Erythritol was detected in measurable amounts only in the plaque of subjects receiving this polyol. Erythritol and xylitol may exert similar effects on some risk factors of dental caries, although the biochemical mechanism of the effects may differ. These in vivo studies were supported by cultivation experiments in which xylitol, and especially erythritol, inhibited the growth of several strains of mutans streptococci.
Bit matrix transpose with tensor product and perfect shuffling (2013)

Efficient implementation of bit-level matrix transpose operations using a new family of perfect shuffle instructions in a word-based micro-processor architecture is investigated. Using a tensor representation of the perfect shuffle index mapping, we show how bit matrix of arbitrary size may be transposed using a minimal sequence of shuffle and pack instructions, and prove the correctness of the code so generated. Specifically, a shuffle decomposition approach, and a block matrix transpose approach are proposed and the performance of these approaches are compared. Implemented with Texas Instruments C64X instruction set, significant performance enhancement is observed.
Charged domains in ferroelectric, polycrystalline yttrium manganite thin films resolved with scanning electron microscopy (2020)

We have investigated ferroelectric charged domains in polycrystalline hexagonal yttrium manganite thin films (Y<sub>1</sub>Mn<sub>1</sub>O<sub>3</sub>, Y<sub>0.95</sub>Mn<sub>1.05</sub>O<sub>3</sub>, Y<sub>1</sub>Mn<sub>0.99</sub>Ti<sub>0.01</sub>O<sub>3</sub>, and Y<sub>0.94</sub>Mn<sub>1.05</sub>Ti<sub>0.01</sub>O<sub>3</sub>) by scanning electron microscopy (SEM) in secondary electron emission mode with a small acceleration voltage. Using SEM at an acceleration voltage of 1.0 kV otherwise homogenous surface charging effects are reduced, polarization charges can be observed and polarization directions (±P<sub>z</sub>) of the ferroelectric domains in the polycrystalline thin films can be identified. Thin films of different chemical composition have been deposited by pulsed laser deposition on Pt/SiO<sub>2</sub>/Si structures under otherwise same growth conditions. Using SEM it has been shown that different charged domain density networks are existing in polycrystalline yttrium manganite thin films.

New αIIbβ3 variants in 28 Turkish Glanzmann patients; structural hypothesis for complex activation by residues variations in I-EGF domains (2021)

Glanzmann thrombasthenia (GT) is a rare autosomal recessive bleeding disorder characterized by impaired platelet aggregation due to defects in integrin αIIbβ3, a fibrinogen receptor. Platelet phenotypes and allelic variations in 28 Turkish GT patients are reported. Platelets αIIbβ3 expression was evaluated by flow cytometry. Sequence analyzes of <i>ITGA2B</i> and <i>ITGB3</i> genes allowed identifying nine variants. Non-sense variation effect on αIIbβ3 expression was studied by using transfected cell lines. 3D molecular dynamics (MDs) simulations allowed characterizing structural alterations. Five new alleles were described. αIIb:p.Gly423Asp, p.Asp560Ala and p.Tyr784Cys substitutions impaired αIIbβ3 expression. The αIIb:p.Gly128Val substitution allowed normal expression; however, the corresponding NM_000419.3:c.476G>T variation would create a cryptic donor splicing site altering mRNA processing. The β3:p.Gly540Asp substitution allowed αIIbβ3 expression in HEK-293 cells but induced its constitutive activation likely by impairing αIIb and β3 legs interaction. The substitution alters the β3 I-EGF-3 domain flexibility as shown by MDs simulations. GT variations are mostly unique although the NM_000419.3:c.1752 + 2 T > C and NM_000212.2:c.1697 G > A variations identified in 4 and 8 families, respectively, might be a current cause of GT in Turkey. MD simulations suggested how some subtle structural variations in the β3 I-EGF domains might induce constitutive activation of αIIbβ3 without altering the global domain structure.
Conflict Resolution of Mind and Body Using Ayurveda and Yoga (2020)

This chapter will focus on Ayurveda and yoga to understand the power of the mind and body to resolve conflict. The fundamental principles of Ayurveda will be discussed in relation to the universe and body because we are a microcosm of the macrocosm. A society so rich in science, pharmaceuticals, and healthcare professionals still struggles for good health. Society continues to remain malnourished even though overfed with food causing the human mind to turn to other modalities like Ayurveda and yoga. As contemporary medicine starts with disease, Ayurveda begins with health with the focus on maintaining the health of the healthy. The fundamental principles of Ayurveda regarding the biological humors (doshas) will be discussed in relation to the five elements of ether, air, fire, water, earth. The main focus will be diet and lifestyle. This chapter will provide pearls of Ayurvedic wisdom to allow one to assimilate these practices into daily life.
Ligand Binding and Structural Analysis of a Human Putative Cellular Retinol-binding Protein (2002)

Three cellular retinol-binding protein (CRBP) types (CRBP I, II, and III) with distinct tissue distributions and retinoid binding properties have been structurally characterized thus far. A human binding protein, whose mRNA is expressed primarily in kidney, heart, and transverse colon, is shown here to be a CRBP family member (human CRBP IV), according to amino acid sequence, phylogenetic analysis, gene structure organization, and x-ray structural analysis. Retinol binding to CRBP IV leads to an absorption spectrum distinct from a typical holo-CRBP spectrum and is characterized by an affinity (K(d) = approximately 200 nm) lower than those for CRBP I, II, and III, as established in direct and competitive binding assays. As revealed by mutagenic analysis, the presence in CRBP IV of His(108) in place of Gln(108) is not responsible for the unusual holo-CRBP IV spectrum. The 2-A resolution crystal structure of human apo-CRBP IV is very similar to those of other structurally characterized CRBPs. The side chain of Tyr(60) is present within the binding cavity of the apoprotein and might affect the interaction with the retinol molecule. These results indicate that human CRBP IV belongs to a clearly distinct CRBP subfamily and suggest a relatively different mode of retinol binding for this binding protein.
Analysis of RP-HPLC Loading Conditions for Maximizing Peptide Identifications in Shotgun Proteomics (2009)

Substantial energy and resources have been invested in improving mass spectrometry (MS) instrumentation, upstream sample preparation protocols, and database search strategies to maximize peptide and protein identifications. The role of HPLC sample loading methods in maximizing MS identifications has been largely overlooked, and there exists an immense heterogeneity in the methods employed in the proteomics literature. We sought to optimize loading methods by testing multiple loading conditions (buffer composition, resin, initial gradient) using tryptic digests of an 18 protein mixture and whole yeast lysate. The loading buffer acetonitrile (ACN) concentration greatly affected peptide identifications: up to a 26% increase in peptide identifications was observed by decreasing the ACN concentration from 5 to 2% during sample loading. Hydrophilic peptides were the main contributors to the increase in peptide identifications and, at higher ACN concentrations, were washed from the precolumn during desalting. Sampling of the hydrophilic peptides was enhanced by using a shallow initial ACN gradient. The results were found to be resin-specific and not generalizable. Our investigation demonstrates the often unappreciated importance of optimizing sample loading conditions to reflect the aims of the research and the characteristics of the LC configurations employed.
Polymer nanocomposite ionogels, high-performance electrolyte membranes (2010)

A sol–gel synthesis using modified poly(methyl methacrylate) (PMMA) bearing trimethoxysilane groups and tetraethoxysilane (TEOS) allowed immobilization of very high loadings of ionic liquid [BMIm][NTf2] within nanocomposite PMMA-silica membranes. The ionic liquid (IL) provided both flexibility and ionic conductivity, while the silica nanofiller covalently bonded to the polymer chains maintained mechanical strength, as shown by a DMA and tensile test. Complex impedance spectroscopy evidenced a critical threshold in ionic conductivity around 76%, which was ascribed to an unusual transition from “polymer-in-salt” to “quasi-liquid” electrolyte behaviour. Outstanding IL loadings as high as 90 wt% were reached, resulting in the same ionic conductivity as the pure IL.
Systematic Approach for Transient Stability Evaluation of Grid-Tied Converters during Power System Faults (2019)

Grid-tied converters subject to severe grid faults might experience transient instability and loss of synchronization. As studying this phenomenon deals with large-signal disturbances, a linearized equivalent will no longer be an accurate approximation of the system. Consequently, a highly used approach is to perform time-domain simulation studies of a detailed model of the system to assess the transient stability and overall performance. However, such an approach might result in a large computational burden and limited physical insight to the system. To address this issue, this paper presents a systematic approach to assess the transient stability of the inherently nonlinear problem alongside an methodology for setting the control parameters to avert transient instability. Using a simplified model for the converter, it is shown that phase-plane analysis is accurate for analyzing the transient synchronization stability. To that end, a critical damping ratio of the phase-locked loop can be found to identify the domain of attraction of the state trajectories, which has been experimentally verified. Using this together with an engineering insight to the system, one can set the controller parameters of the phase-locked loop such to guarantee stability during severe grid faults and perform worst-case planning settings for the controller and protection devices.
Colon Sarcoidosis Mimicking Cancer at 18F-FDG PET/CT (2020)

This 68-year-old woman with a 9-year history of skin sarcoidosis presented with abdominal pain, bloating, and diarrhea. Following positive occult fecal blood, a diagnosis of ascending colon sarcoidosis was pathologically confirmed after colonoscopy. FDG PET/CT was performed for sarcoid staging, and the ascending colon demonstrated the only focal site of active sarcoidosis (SUVmax = 10).
Compositionally graded relaxed AlGaN buffers on semipolar GaN for mid-ultraviolet emission (2012)

In this Letter, we report on the growth and properties of relaxed, compositionally graded AlxGa1 − xN buffer layers on freestanding semipolar (202¯1) GaN substrates. Continuous and step compositional grades with Al concentrations up to x = 0.61 have been achieved, with emission wavelengths in the mid-ultraviolet region as low as 265 nm. Coherency stresses were relaxed progressively throughout the grades by misfit dislocation generation via primary (basal) slip and secondary (non-basal) slip systems. Threading dislocation densities in the final layers of the grades were less than 106/cm2 as confirmed by plan-view transmission electron microscopy and cathodoluminescence studies.

Multi-Object Tracking of Sinusoidal Components in Audio with the Gaussian Mixture Probability Hypothesis Density Filter (2007)

We address the problem of identifying individual sinusoidal tracks from audio signals using multi-object stochastic filtering techniques. Attractive properties for audio analysis include that it is conceptually straightforward to distinguish between measurements that are generated by actual targets and those which are false alarms. Moreover, we can estimate target states when observations are missing and can maintain the identity of these targets between time-frames. We illustrate a particularly useful variant, the Probability Hypothesis Density (PHD) filter, on measurements of musical harmonics determined by high resolution subspace methods which provide very accurate estimates of amplitudes, frequencies and damping coefficients of individual sinusoidal components. We demonstrate this approach in a musical audio signal processing application for extracting frequency tracks of harmonics of notes played on a piano.

On the use of Sub-Space Clustering &amp; Evidence Accumulation for traffic analysis &amp; classification (2011)

Driven by the well-known limitations of port and payload-based analysis techniques, the use of Machine Learning for Internet traffic analysis and classification has become a fertile research area during the past half-decade. In this paper we introduce a novel unsupervised approach to identify different classes of IP flows sharing similar characteristics. The unsupervised analysis is accomplished by means of robust clustering techniques, using Sub-Space Clustering, Evidence Accumulation, and Hierarchical Clustering algorithms to explore inter-flows structure. Our approach permits to identify natural groupings of traffic flows, combining the evidence of data structure provided by different partitions of the same set of traffic flows. The technique is further used to build an automatic flow classification model, using a semi-supervised-learning-based approach. The approach uses only a reduced fraction of labeled flows to map the identified clusters into their associated most-probable originating application, which strongly simplifies its calibration. We evaluate the performance of our techniques using real traffic traces, additionally comparing their performance against previously proposed clustering-based classification methods.

Subtle gaze-dependent techniques for visualising display changes in multi-display environments (2013)

This paper explores techniques for visualising display changes in multi-display environments. We present four subtle gaze-dependent techniques for visualising change on unattended displays called FreezeFrame, PixMap, WindowMap and Aura. To enable the techniques to be directly deployed to workstations, we also present a system that automatically identifies the user's eyes using computer vision and a set of web cameras mounted on the displays. An evaluation confirms this system can detect which display the user is attending to with high accuracy. We studied the efficacy of the visualisation techniques in a five-day case study with a working professional. This individual used our system eight hours per day for five consecutive days. The results of the study show that the participant found the system and the techniques useful, subtle, calm and non-intrusive. We conclude by discussing the challenges in evaluating intelligent subtle interaction techniques using traditional experimental paradigms.
Amphetamines for attention deficit hyperactivity disorder (ADHD) in children and adolescents (2016)

Most of the included studies were at high risk of bias and the overall quality of the evidence ranged from low to very low on most outcomes. Although amphetamines seem efficacious at reducing the core symptoms of ADHD in the short term, they were associated with a number of adverse events. This review found no evidence that supports any one amphetamine derivative over another, and does not reveal any differences between long-acting and short-acting amphetamine preparations. Future trials should be longer in duration (i.e. more than 12 months), include more psychosocial outcomes (e.g. quality of life and parent stress), and be transparently reported.
