Comparison of linear accelerations from three measurement systems during “reach & grasp” (2006)

Given the increased use of accelerometers in movement analysis, validation of such inertial sensors against conventional 3D camera systems and performance comparisons of different sensors have become important topics in biomechanics. This paper evaluates and compares linear acceleration trajectories obtained from two different 3D accelerometers and derived from Vicon position data for an upper limb "reach & grasp" task. Overall, good correspondence between the three measurement systems was obtained. Sources of error are discussed.
Field emission enhancement by electric field activation in screen‐printed carbon Nanotube film (2005)

Abstract By applying a critical field treatment instead of the conventional surface treatments such as soft rubber roller, ion beam irradiation, adhesive taping, and laser irradiation, electron emission properties of screen‐printed carbon nanotubes (CNTs) were enhanced and investigated based on the emission current‐voltage characteristics through scanning electron microscopy. After nanotube emitters were activated at the applied electric‐field of 2.5 V/um, the electron emission current density with good uniform emission sites reached the value of 2.13 mA/cm2, which is 400 times higher than that of the untreated sample, and the turn‐on voltage decreased markedly from 700 to 460 V. In addition, enhancement of the alignment of CNTs to the vertical direction was observed.
Effect of Cold Working on Mechanical Damping Capacity of Al&ndash;Co Alloys (1993)

The logarithmic decrement (δ) of elastic vibration and rigidity modulus (G) were investigated for Al–Co alloys containing 0.2 to 10.0 mass% Co. δ and G were measured using an inverted torsion pendulum. In furnace-cooled and water-quenched specimens, δ is slightly increased by adding Co, but its absolute value is about 9×10−3 which is considerably small. The δ of furnace-cooled specimen is slightly higher than that of water-quenched one. The δ of all alloys is drastically increased by cold working after heat treatment. The value of δ in cold-worked specimens rapidly increases with the amount of Co upto about 1 mass% Co, and then the value either remains constant or decreases slightly. The alloys cold-drawn after furnace-cooled yield higher δ values than those cold-drawn after water-quenching. The difference between them is greater when the degree of working is smaller. In the furnace-cooled and water-quenched specimens, G increases as the amount of Co increases. G is decreased by cold working after heat treatment because dislocations increase. The increase in δ by cold working seems to be due to a drastic increase in the dislocation density and a decrease in the grain sizes of the α and β phases.
On a Possibility of Wavelength-Domain-Multiplication Memory Using Quantum Boxes (1995)

A new use of quantum boxes for wavelength-domain-multiplication optical memory applications is proposed. Persistent spectral-hole burning mechanism based on photo-creation of electron-hole pairs and their spatial separation by carrier tunneling is described. We discuss the feasibility of its application to optical data storage with emphasis on the memory duration and the multiplexing factor, that is, the possible number of bits stored in a laser-beam spot following the discussion by Moerner and Levenson.
Estimation of Drug Resistance by Flow Cytometry (2003)

Drug resistance is a subject that covers two areas. In one case it refers to the ability of microbes to defeat antibiotics. In a different setting it refers to the ability of cancer cells to resist chemotherapy. In the first case, the drug resistance is evaluated on the basis of the percentage of viable cells after treatment with a given drug concentration. This is then simply an application of viability testing, the reader interested in this specific area is referred to Chapter 7 .
Predictive Current Control for an Active Power Filter With <italic>LCL</italic>-Filter (2017)

Voltage source inverter based active power filters are widely used for the compensation of harmonic currents, especially in industrial environments. Loads such as three-phase diode rectifiers, thyristor-based rectifiers or variable-speed drives can cause relevant harmonics up to the 50th order or even higher, depending on the line filter. Usually, the control of the harmonics is either done in multiple rotating frames, where the harmonics appear as dc values, or by resonant controllers in a stationary frame. At this, the calculation effort is rising with the number of harmonics to compensate. In this paper, a predictive current control scheme is presented. It is implemented in addition to common PI current control and used for a three-phase four-wire LCL-filter-based active power filter. Inaccuracies in the model caused by parameter variations are compensated by an additional control structure. Both structures are related only with low computational effort and are not depending on the desired number of the harmonics to compensate. Experimental tests are demonstrating, that both structures individually, and especially the combination of both, are offering a very good behavior in the steady state and in the case of load changes.

T2-relaxation time measurement of metabolite peak in gastric tissue using ex vivo proton magnetic resonance spectroscopy imaging (2005)

The purpose of this study is to measure T2-relaxation time of metabolite peak in human gastric tissue using ex vivo 1H magnetic resonance spectroscopic imaging (MRSI or chemical shift imaging: CSI), and to assess the clinical usefulness. Also, T2-relaxation time map was compared with biochemical metabolite map. T2-relaxation time of metabolite peak at 1.33 ppm, lipid methylene, were calculated pixel by pixel. T2 map of metabolite peak was compared to the metabolite-peak intensity map.
Gene Regulation by Thyroid Hormone Receptors (2003)

The transfection and overexpression of the cDNA encoding the thyroid hormone receptor (TR) in mammalian cells has shed light into several aspects of the function and biological characteristics of the TR in cells. Using this method, thyroid hormone and TR-responsive genes and response elements were identified. As well, the diversity of TR binding sequences and the effect of heterodimerization with retinoid x receptor (RXR) were elucidated. Furthermore, the functional domains of the TR, its activation domain, hormone-dependent transactivation function, nuclear localization, dimerization properties, and silencing domain could be identified and characterized (Fig. 1), for (reviews see refs. 1-3). The identification and analysis of functional domains of TR was accomplished mostly by generating fusion proteins of TR parts to a heterologous DNA-binding domain (DBD), such as that of the GAL4-DBD. These fusion proteins permitted the determination of amino acids required for a specific receptor function and allowed the dissection and separate characterization of the various functions of TR (4,5).
Multifunctional Materials: Transparent Reactive Armor Utilizing Single-Walled Carbon Nanotube Frameworks (2010)

Abstract : The goal of this project is to enable a new class of transparent energetic materials from nanotube-organic scaffolds, evaluate the feasibility of transparent reactive armor for defense applications, and to characterize and develop design rules for such materials through preliminary measurements of their properties. Specifically, we focused on developing thin one-dimensional (1-D) chemical actuators with high velocity and high thrust-to-mass ratio. We have completed extensive modeling and the development of engineering design rules. We synthesized and demonstrated the feasibility of several new types of nano-energetic materials.
Preliminary investigations with a new indentation type tonometer (2002)

A new type of tonometer is being developed and tested at the University of New Hampshire (UNH) that will allow not only ocular tonometric recordings but a vast variety of tonometric measurements. The UNH tonometer (UNHT) set in the ocular mode to measure intraocular pressure (IOP) in humans was tested against a Goldmann applanation tonometer. Eyes were simulated with balloons filled with saline and of the same radius of curvature as the human eye. Three-quarters of the balloon was covered with an inelastic membrane that force the remaining quarter area to simulate the cornea. Saline was introduced into the simulated eyes via hypodermic needle. Measurements were taken with the Goldmann tonometer (GT) and then the UNHT as saline was introduced into the simulated eye at 5-mmHg increments from 10-mmHg to 40-mmHg. Tests comparing the UNHT in the ocular mode to the GT indicate that the UNHT is linear but follows a regression formula of UNHT=8.48+0.446*GT.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Results of earth fault measurements in an earth fault compensated 110 kV system (2001)

The earth fault compensation has well known favourable effects on the operation of distribution networks. The biggest benefit is the fact that an arc-over vanishes automatically in general, i.e. without intervention of the operation personnel, and thus remains without affecting the customers. The exact knowledge of the damping factor, the detuning and the unbalance as well as the harmonics in the residual current are substantial prerequisites for safe ground fault extinction and thus for a reliable line operation. These quantities are the basis for the planning of further network expansion. To get reliable information, earth fault measurements in the described 110 kV system were carried out. In this paper the evaluations of the above-mentioned parameters via operational indicators are compared with the results of direct earth fault measurements.
Evaluation and Management of Mandibular Fracture (2019)

The mandibular bone is an important component of the facial bone, which has a unique role in digestive system, speech, and facial esthetics. For these important functions of mandibular bone, it is vital that surgeons should not only treat function but also consider the esthetics together. Mandibular fractures are among the most common traumatic injuries of the maxillofacial region. Even though treatment modalities are well established and being practiced for a long time, untreated and postoperative complications still decrease the patient’s quality of life. This chapter aims to describe the cause, clinical presentations, diagnoses, and current treatment methods on the basis of resent literature.
Copper-Catalyzed Enantioselective Substitution of Allylic Carbonates with Diboron:  An Efficient Route to Optically Active α-Chiral Allylboronates (2007)

A method for the synthesis of alpha-chiral allylboronates featuring the Cu(I)-catalyzed enantioselective substitution of readily available allylic carbonates with a diboron is described. Using this method, various alpha-chiral allylboronates, including functionalized allylboronates, were successfully synthesized, with high enantiomeric purity.
A Data-Driven Reflectance Mode (2023)

We present a generative model for isotropic bidirectional reflectance distribution functions (BRDFs) based on acquired reflectance data. Instead of using analytical reflectance models, we represent each BRDF as a dense set of measurements. This allows us to interpolate and extrapolate in the space of acquired BRDFs to create new BRDFs. We treat each acquired BRDF as a single high-dimensional vector taken from a space of all possible BRDFs. We apply both linear (subspace) and non-linear (manifold) dimensionality reduction tools in an effort to discover a lower-dimensional representation that characterizes our measurements. We let users define perceptually meaningful parametrization directions to navigate in the reduced-dimension BRDF space. On the low-dimensional manifold, movement along these directions produces novel but valid BRDFs.
An Infrared Thermal Image Processing Framework for Defect Detection of a Metal Part with Rough Surface (2012)

We propose an infrared thermal image processing framework based on a modified fuzzy c-means clustering algorithm with revised similarity measure in this paper. The framework can realize the defect detection of a metal part with rough surface. Firstly, a comprehensive method is used to preprocess infrared thermal image. Secondly, the preprocessed image is segmented using modified fuzzy c-means clustering algorithm with revised similarity measure. Finally, taking the average gray level of each cluster in the original gray scale image as a feature, defect cluster is recognized. Experimental result shows that the proposed framework has very promising performance and can obtain precise information of defects on a metal part with rough surface.
Deep Learning‐Enabled Multiplexed Point‐of‐Care Sensor using a Paper‐Based Fluorescence Vertical Flow Assay (2023)

Multiplexed computational sensing with a point-of-care serodiagnosis assay to simultaneously quantify three biomarkers of acute cardiac injury is demonstrated. This point-of-care sensor includes a paper-based fluorescence vertical flow assay (fxVFA) processed by a low-cost mobile reader, which quantifies the target biomarkers through trained neural networks, all within <15 min of test time using 50 µL of serum sample per patient. This fxVFA platform is validated using human serum samples to quantify three cardiac biomarkers, i.e., myoglobin, creatine kinase-MB, and heart-type fatty acid binding protein, achieving less than 0.52 ng mL<sup>-1</sup> limit-of-detection for all three biomarkers with minimal cross-reactivity. Biomarker concentration quantification using the fxVFA that is coupled to neural network-based inference is blindly tested using 46 individually activated cartridges, which shows a high correlation with the ground truth concentrations for all three biomarkers achieving >0.9 linearity and <15% coefficient of variation. The competitive performance of this multiplexed computational fxVFA along with its inexpensive paper-based design and handheld footprint makes it a promising point-of-care sensor platform that can expand access to diagnostics in resource-limited settings.
Evaluation of the antifungal potential of Brazilian Cerrado medicinal plants (2009)

Therapeutic limitations, development of fungal drug resistance, drug-related toxicity, drug interactions and insufficient bioavailability of the currently available antifungal drugs have made the development of drugs necessary that would be able to treat the emerging fungal infections. The Cerrado is the second greater biome of Brazil and it was identified as one of the most distinguished biomes of South America, becoming an important source of innovative vegetal molecules to treat several conditions. Thus, the objective of this study was to evaluate the antifungal potential of Cerrado plants, mainly those used to treat infections and wounds. A total of 57 extracts were screened by the agar-well diffusion technique against Candida albicans and Trichophyton rubrum. The most promising extracts were tested in smaller concentrations and their minimal inhibitory concentrations (MIC) were determined by microdilution method. Results were analysed statistically by anova tests. Extracts of Kielmeyera coriacea, Renealmia alpinia, Stryphnodendron adstringens and Tabebuia caraiba were very active against T. rubrum, presented geometric means of the MIC values between 170.39 and 23.23 microg ml(-1). Extracts of Cerrado plants are of particular interest as source of new agents for the treatment of dermatophytic infections.
Increased Adherence to the Mediterranean Diet after Lifestyle Intervention Improves Oxidative and Inflammatory Status in Patients with Non-Alcoholic Fatty Liver Disease (2022)

A greater adherence to the MedDiet is related to greater improvements in IFC, cardiorespiratory fitness, and pro-oxidative and proinflammatory status in NAFLD patients after a 6-month nutritional intervention based on the MedDiet.
Exchange Interaction between Single Magnetic Adatoms (2007)

The magnetic coupling between single Co atoms adsorbed on a copper surface is determined by probing the Kondo resonance using low-temperature scanning tunneling spectroscopy. The Kondo resonance, which is due to magnetic correlation effects between the spin of a magnetic adatom and the conduction electrons of the substrate, is modified in a characteristic way by the coupling of the neighboring adatom spins. Increasing the interatomic distance of a Cobalt dimer from 2.56 to 8.1 A we follow the oscillatory transition from ferromagnetic to antiferromagnetic coupling. Adding a third atom to the antiferromagnetically coupled dimer results in the formation of a collective correlated state.
ATR-FTIR Study of Water in Nafion Membrane Combined with Proton Conductivity Measurements during Hydration/Dehydration Cycle (2011)

We have conducted combined time-resolved attenuated total reflection Fourier transform infrared (ATR-FTIR) and proton conductivity measurements of Nafion NRE211 membrane during hydration/dehydration cycles at room temperature. Conductivity change was interpreted in terms of different states of water in the membrane based on its δ(HOH) vibrational spectra. It was found that hydration of a dry membrane leads first to complete dissociation of the sulfonic acid groups to liberate hydrated protons, which are isolated from each other and have δ(HOH) vibrational frequency around 1740 cm(-1). The initial hydration is not accompanied by a significant increase of the proton conductivity. Further hydration gives rise to a rapid increase of the conductivity in proportion to intensity of a new δ(HOH) band around 1630 cm(-1). This was interpreted in terms of formation of channels of weakly hydrogen-bonded water to combine the isolated hydrophilic domains containing hydrated protons and hydrated sulfonate ions produced during the initial stage of hydration. Upon dehydration, proton conductivity drops first very rapidly due to loss of the weakly hydrogen bonded water from the channels to leave hydrophilic domains isolated in the membrane. Dehydration of the protons proceeds very slowly after significant loss of the proton conductivity.
Medium‐chain fatty acids ameliorate insulin resistance caused by high‐fat diets in rats (2009)

The chain length of saturated fatty acids in isocaloric diets affects insulin sensitivity, lipid metabolism and mitochondrial fatty acid oxidation without influencing body weight. While dietary LCFA clearly impair insulin sensitivity and lipid metabolism, MCFA seem to protect from lipotoxicity and subsequent insulin resistance without caloric restriction.
