Noninvasive Monitoring of Hemoglobin (2004)

The efficacy of a noninvasive hemoglobin monitoring device (Astrim, Sysmex, Kobe, Japan) was evaluated for healthy volunteers and for patients with hematologic disorders. At the same time, the effects of WBC counts on noninvasive monitoring were studied by clinical evaluation and in ex vivo experiments. The hemoglobin levels determined by the device (Ast-Hb) and a conventional analyzer (T-Hb) were compared. The coefficient of correlation between findings with the Ast-Hb and the T-Hb for healthy volunteers was r = 0.626, whereas that for patients with hematologic disorders was r = 0.762. A comparison of the ratios of measurement errors in hemoglobin levels by Ast-Hb and T-Hb indicated that the number of WBCs had no effect on hemoglobin monitoring. Moreover, ex vivo studies using isolated WBCs and an optical model that imitates blood vessels and tissue in human fingers confirmed these results. Therefore, this new hemoglobin monitoring device can be expected to be useful for continuous hemoglobin monitoring.
Linear Analysis of Nonlinear Properties (2018)

In Chapter 1 we found that both load-induced and thermally induced stress is readily calculated for linear elastic material properties using Hooke’s law. In some cases, however, material behavior is nonlinear, and hence one needs to make use of nonlinear theory. Since this is now a departure from the usual Hookean approach, the use of plastic analysis may be required. However, we can avoid this complexity in some situations. In Chapter 4 we saw an example of nonlinear behavior of the CTE with temperature, which we handle quite nicely using secant CTE properties. We discuss this application and extend it to apply to a nonlinear elastic modulus. A theoretical approach is presented to calculate stresses for nonlinear, non-Hookean materials.

Interaction of germanium analogue of organic isonitrile with Cu(i) imide in side-on mode (2023)

[NHC → GeN(Ar)Cu<sub>2</sub>NAr]<sub>2</sub>, the formal adduct of germanium analogue of organic isonitrile [GeNAr] with Cu(I) imide [(Cu<sub>2</sub>NAr)<sub>2</sub>] (Ar = 2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>) was prepared from the N-heterocyclic carbene (NHC) stabilized acyclic germylene Ge[N(H)Ar]<sub>2</sub> by reacting with two equivalents of <i>n</i>BuLi and CuCl(PPh<sub>3</sub>)<sub>3</sub>. As elucidated by X-ray crystal structural characterization, the two separated [GeNAr] moieties interacted with [(Cu<sub>2</sub>NAr)<sub>2</sub>] core in the side-on mode.
The effect of dose rate and multiple fractions per day on radiation-induced lung damage in mice (1984)

The human lungs are relatively radiosensitive organs, requiring a single dose of only 9.0 Gy (corrected lung dose) to produce a 25% incidence of acute radiation pneumonitis syndrome following irradiation of the upper half of the body (Van Dyk et al, 1981). This low tolerance limits the therapeutic potential of whole lung irradiation for pulmonary metastases, and radiation damage may have been responsible for pneumonitis in 30–40% of leukaemic patients receiving total body irradiation (TBI) prior to bone marrow transplantation (Keane et al, 1981). Split-dose experiments in laboratory animals show that the lungs have a considerable capacity for repair of sublethal damage (Field et al, 1976). Peters et al (1979) have proposed that fractionated TBI should lead to therapeutic gain in the treatment of leukaemia with TBI, since cells of haemopoietic origin show less capacity for repair of sublethal radiation injury than the lung.
Interference cancelling characteristics of DFE transversal‐combining diversity in mobile radio environment–comparisons with metric‐combining schemes (1994)

Abstract This paper considers the decision feedback transversal‐combining (TC) diversity reception system in the digital mobile communication, and describes experimentally the interference cancelling characteristics of decision feedback equalizer‐type (DFE) TC diversity reception through laboratory tests. Three kinds of interference signals are considered: the intersymbol interference (ISI), the cochannel interference (CCI), and the adjacent channel interference (ACI). The exponentially weighted RLS, which executes the least‐square method in realtime, is employed in the adaptive control of the combining coefficients. It is shown first that the method for equalization and diversity combining can be classified into the TC and the metric combining (MC), among which TC has the linear interference cancelling effect. By 40 kbit/s quadri‐phase‐shift keying (QPSK) transmission experiments under Rayleigh fading condition, the following properties of TC are shown compared to MC: (1) In ISI, dominant condition in double path model, the average BER performance for average E b / N 0 values over 20 dB; (2) For CCI, dominant condition BER performance of TC is better than that of MC by 5 dB in average CIR at average BER of 10 −2 .
Dioxygen Reactivity of a Copper(I) Complex with a N3S Thioether Chelate; Peroxo−Dicopper(II) Formation Including Sulfur-Ligation (2006)

Employing a tetradentate N3S(thioether) ligand, LN3S, dioxygen reactivity of a copper(I) complex, [(LN3S)CuI]+ (1) was examined. In CH2Cl2, acetone (at -80 degrees C), or 2-methyltetrahydrofuran (at -128 degrees C), 1 reacts with O2 producing the end-on bound peroxodicopper(II) complex [{(LN3S)CuII}2(mu-1,2-O2(2-))]2+ (2), the first reported copper-dioxygen adduct with sulfur (thioether) ligation. Its absorption spectrum contains an additional low-energy feature (but not a Cu-S CT band) compared to the previously well-characterized N4 ligand complex, [{(TMPA)CuII}2(mu-1,2-O2(2-))]2+ (3) (TMPA = tris(2-pyridylmethyl)amine). Resonance Raman spectroscopy confirms the peroxo formulation {nu(O-O) = 817 cm-1 (16-18O2 Delta = 46 cm-1) and nu(Cu-O) = 545 cm-1 (16-18O2 Delta = 26 cm-1), in close analogy to that known for 3 {nu(O-O) = 827 cm-1 and nu(Cu-O) = 561 cm-1}. Direct evidence for thioether ligation comes from EXAFS spectroscopy {Cu K-edge; Cu-S = 2.4 A}.

Fluorometric Cell Detection Method Using Complement-Mediated Cytolytic Reaction and Imaging Sensor System (1987)

Abstract A rapid and sensitive cell detection method using complement-mediated cytolytic reaction and an image processing system was developed. The present system consists of SIT video camera, fluorescent microscope and personal computer system equipped with image memory board. Target cell cytolysis caused by 3C4 monoclonal antibody and complement was determined using DNA (or RNA) specific fluorescent dye, propidium iodide. Target cells, guinea pig hepatocarcinoma cells, could be detected quantitatively when its content was above 2%. Measurement time was approximately 5 minutes.

Unusual phenotype with progressive vertebral fusion in a girl with an apparently balanced t(10;20)(p11;p13) translocation (2005)

We report the case of a girl presenting with an unusual form of multiple joint fusion. Skeletal abnormalities consisted of radioulnar synostosis and vertebral fusions without any carpal, digital or tarsal involvement, and broad ribs and clavicles. Spinal X-rays were available from age 4 to 21, demonstrating that the spinal involvement was progressive and led to a complete anterior and lateral fusion of vertebrae. A complete sequencing of the NOGGIN gene failed to find any mutation. In addition, this girl was carrier of an apparently balanced reciprocal translocation t(10;20)(p11;p13). We investigated the role of the BMP2A gene as a potential candidate gene. Fluorescence in situ hybridization with YAC probes from chromosome 20 showed that the BMP2A gene was not disrupted by the translocation breakpoint.
Cancer Cell Lines for Drug Discovery and Development (2014)

Despite the millions of dollars spent on target validation and drug optimization in preclinical models, most therapies still fail in phase III clinical trials. Our current model systems, or the way we interpret data from them, clearly do not have sufficient clinical predictive power. Current opinion suggests that this is because the cell lines and xenografts that are commonly used are inadequate models that do not effectively mimic and predict human responses. This has become such a widespread belief that it approaches dogma in the field of drug discovery and optimization and has spurred a surge in studies devoted to the development of more sophisticated animal models such as orthotopic patient-derived xenografts in an attempt to obtain more accurate estimates of whether particular cancers will respond to given treatments. Here, we explore the evidence that has led to the move away from the use of in vitro cell lines and toward various forms of xenograft models for drug screening and development. We review some of the pros and cons of each model and give an overview of ways in which the use of cell lines could be modified to improve the predictive capacity of this well-defined model.
INCREASING THE SELECTIVITY AND SENSITIVITY OF GAS SENSORS FOR THE DETECTION OF EXPLOSIVES (2014)

Over the past decade, the use of improvised explosive devices (IEDs) has increased, domestically and internationally, highlighting a growing need for a method to quickly and reliably detect explosive devices in both military and civilian environments before the explosive can cause damage. Conventional techniques have been successful in explosive detection, however they typically suffer from enormous costs in capital equipment and maintenance, costs in energy consumption, sampling, operational related expenses, and lack of continuous and real-time monitoring. The goal was thus to produce an inexpensive, portable sensor that continuously monitors the environment, quickly detects the presence of explosive compounds and alerts the user. In 2012, here at URI, a sensor design was proposed for the detection of triacetone triperoxide (TATP). The design entailed a thermodynamic gas sensor that measures the heat of decomposition between trace TATP vapor and a metal oxide catalyst film. The sensor was able to detect TATP vapor at the part per million level (ppm) and showed great promise for eventual commercial use, however, the sensor lacked selectivity. Thus, the specific objective of this work was to take the original sensor design proposed in 2012 and to make several key improvements to advance the sensor towards commercialization. It was demonstrated that a sensor can be engineered to detect TATP and ignore the effects of interferent H2O2 molecules by doping SnO2 films with varying amounts of Pd. Compared with a pure SnO2 catalyst, a SnO2, film doped with 8 wt. % Pd had the highest selectivity between TATP and H2O2. Also, at 12 wt. % Pd, the response to TATP and H2O2 was enhanced, indicating that sensitivity, not only selectivity, can be increased by modifying the composition of the catalyst. An orthogonal detection system was demonstrated. The platform consists of two independent sensing mechanisms, one thermodynamic and one conductometric, which take measurements from the same catalyst simultaneously and provide a redundancy in response for positive explosive identification. TATP, 2,6-DNT and ammonium nitrate were reliably detected. Each analyte displayed a unique conductometric signature and the results indicated a detection limit at the ppb level. A preconcentrator was designed to enhance the sensitivity of the sensor and was successfully demonstrated. The magnitude of the sensor response increased from by 50% and the preconcentrator could be operated semi-continuously, maintaining one of the most attractive features of this sensor platform: the capability to operate in real time.

Remarkable orientational effects in the displacement of the fluorine from heptafluoro-isoquinoline and -quinoline towards sulfur nucleophiles. Further reactions with oxygen nucleophiles (1993)

Heptafluoroisoquinoline 1 and heptafluoroquinoline 2 have been treated with a variety of sulfur and oxygen nucleophiles and some reactivities have been measured relative to treatment with ethoxide. The significant feature is that the major sites of attack by the sulfur and the oxygen nucleophiles are significantly different: attack occurs at the 6-position by sulfur and the 1-position by oxygen nucleophiles in the isoquinoline derivative 1 irrespective of the relative reactivities; and at the 4-position by sulfur and at both the 2- and 4-positions by oxygen nucleophiles in the quinoline derivative 2. The results have been rationalised on the basis of the relative hardness/softness of the nucleophiles and the known activating influences of the fluorine atoms at sites remote from the reaction centre.
Dynamically controlled plasmonic nano-antenna phased array utilizing vanadium dioxide (2017)

We propose and analyze theoretically an approach for realizing a tunable optical phased-array antenna utilizing the properties of VO2 for electronic beam steering applications in the near-IR spectral range. The device is based on a 1D array of slot nano-antennas engraved in a thin Au film grown over VO2 layer. The tuning is obtained by inducing a temperature gradient over the device, which changes the refractive index of the VO2, and hence modifies the phase response of the elements comprising the array, by producing a thermal gradient within the underlying PCM layer. Using a 10-element array, we show that an incident beam can be steered up to with respect to the normal, by applying a gradient of less than 10°C.

Methods for reducing visual discomfort in stereoscopic 3D: A review (2016)

Visual discomfort is a significant obstacle to the wider use of stereoscopic 3D displays. Many studies have identified the most common causes of discomfort, and a rich body of literature has emerged in recent years with proposed technological and algorithmic solutions. In this paper, we present the first comprehensive review of available image processing methods for reducing discomfort in stereoscopic images and videos. This review covers improved acquisition, disparity re-mapping, adaptive blur, crosstalk cancellation and motion adaptation, as well as improvements in display technology.
Development of Mox Ruy Sez (CO)n electrocatalysts by screen printing and sintering for fuel cell applications (2000)

Electrocatalysts based on molybdenum, ruthenium, and selenium were prepared by screen printing Ru 3 (CO) 12 + Se and Ru 3 (CO) 12 + Mo(CO) 6 + Se mixtures and subsequent sintering at 250°C in air or Se atmosphere in a tubular furnace. The catalysts were characterised using techniques such as XRD, SEM, TEM, voltammetry, and polarisation (current–potential) measurements. The results indicate that screen printed Ru x Se y (CO) n and Mo x Ru y Se z (CO) n are near amorphous in nature and possess appreciable catalytic activity for the oxygen reduction reaction in a polymer electrolyte (Nafion membrane) fuel cell. The electrocatalytic activity seems to diminish with selenium incorporation in the lattice of the carbonyl clusters formed during synthesis.

Calcium and osteoprotegerin regulate IGF1R expression to inhibit vascular calcification (2011)

We have shown for the first time that IGF1R expression and activity via OPG can modulate VSMC calcification in vitro. We suggest a feedback mechanism: moderate calcium levels increase OPG, which then increases IGF1R to enhance VSMC survival and block calcification induced by calcium. In contrast, high calcium leads to inhibition of IGF1R expression and activity to stimulate VSMC calcification further.
Multi-person tracking based on vertical reference lines and dynamic visibility analysis (2011)

Multiple people tracking from multiple cameras can suffer from various problems, particularly from inter-person occlusions. This paper attempts to solve the problems by analyzing the view visibility and ranking the reliability of the cues from 2D views. It combines the visibility with the smoothness constraints into a probability framework, which offers a more flexible and robust estimation. Moreover, it introduces 3D reference lines to estimate the 2D position of every individual in the input images. These lines can estimate more accurate and robust 2D positions. The experimental results and quantitative evaluations on the standard data set show the effectiveness of the method.
Molecular Characterization and Genetic Diversity of Clade E-Human Head Lice from Guinea (2020)

Pediculus humanus capitis, the head louse, is an obligate blood-sucking ectoparasite that occurs in six divergent mitochondrial haplogroups (A, D, B, F, C and E), each exhibiting a particular geographic distribution. A few years ago, several studies reported the presence of different pathogenic agents in head lice specimens from different clades collected worldwide. These findings suggest that head louse could be a vector for dangerous diseases and therefore a serious public health problem. Herein, we aimed to study the mitochondrial genetic diversity, the PHUM540560 gene polymorphisms profile of head lice collected in Guinea, as well as to screen for the pathogens present in these lice. In 2018, a total of 155 head lice were collected from 49 individuals at the Medicals Centers of rural (Maférinyah village) and urban (Kindia city) areas, in Guinea. All head lice were subjected to genetic analysis and screened for the presence of several pathogens using molecular tools. The results showed that all head lice belonged to the haplogroups C/E using the duplex qPCR which detects both clades. Standard PCR and sequencing revealed that all specimens belonged to the haplogroup E, including 8 haplotypes, whither 6 new identified for the first time in this study. The study of the PHUM540560 gene polymorphisms in our Guinean head lice revealed that 7/40 (17.5%) of our tested samples exhibit three different polymorphism profiles compared to the clade A-head lice PHUM540560 gene profile, while the remaining specimens 33/40 (82,5%) showed the same PHUM540560 gene polymorphism profile as the previously reported clade A-body lice. Molecular investigations of the targeted pathogens revealed only the presence of Acinetobacter species in 9% of our samples using real time PCR. Sequencing results identified highlighted the presence of several Acinetobacter species, including Acinetobacter baumannii (14.3%), Acinetobacter nosocomialis (14.3%), Acinetobacter variabilis (14.3%), Acinetobacter haemolyticus (7.2%), Acinetobacter towneri (7.2%). Furthermore, a candidate new species of Acinetobacter sp. (7.2%) was detected. Positive specimens were collected from 24,5% individuals in Maférinyah. We also investigated in our study the carbapenem’s-resistant profile of A. baumannii, none of our specimens were positive for the following resistance genes blaOXA-21, blaOXA-24 and blaOXA-58. To the best of our knowledge, our study is the first to report the existence of the Guinean haplogroup E, the PHUM540560 gene polymorphism profile as well as the presence of Acinetobacter species in head lice collected from Guinea.
An MPEG-4-compatible stereoscopic/multiview video coding scheme (2006)

In this paper, we propose an efficient codec for multiview video coding, which is compatible with the MPEG-4 video standard. The main views of the multiview video are encoded using an MPEG-4 encoder and the auxiliary views are encoded by joint disparity and motion compensation. An edge-preserving regularization scheme that jointly calculates disparity and motion vectors is performed on the VOP basis. The output of the encoder contains one bitstream for each view, and the main view bitstreams can be decoded by a standard MPEG-4 decoder. In addition, in the case of five-view encoding, we compare four different prediction structures in order to find the best one under certain scenarios. To evaluate the proposed encoder, the MPEG-2 multiview profile (MVP) is implemented on the MPEG-4 platform for fair comparison, which is referred to as MPEG-4 MVP in this paper. Experimental results prove that the proposed encoder achieves a higher image quality at similar bit rate than the conventional scheme and is very promising for the applications including videoconferencing and three-dimensional telepresence.
As-Projective-As-Possible Image Stitching with Moving DLT (2013)

We investigate projective estimation under model inadequacies, i.e., when the underpinning assumptions of the projective model are not fully satisfied by the data. We focus on the task of image stitching which is customarily solved by estimating a projective warp - a model that is justified when the scene is planar or when the views differ purely by rotation. Such conditions are easily violated in practice, and this yields stitching results with ghosting artefacts that necessitate the usage of deghosting algorithms. To this end we propose as-projective-as-possible warps, i.e., warps that aim to be globally projective, yet allow local non-projective deviations to account for violations to the assumed imaging conditions. Based on a novel estimation technique called Moving Direct Linear Transformation (Moving DLT), our method seamlessly bridges image regions that are inconsistent with the projective model. The result is highly accurate image stitching, with significantly reduced ghosting effects, thus lowering the dependency on post hoc deghosting.
Derivation of normal macrophages from human embryonic stem (hES) cells for applications in HIV gene therapy (2006)

Phenotypically normal and functionally competent macrophages could be derived from hES-CD34 cells. Since these cells are susceptible to HIV-1 infection, they provide a uniform source of macrophages for viral infection studies. Based on these results, it is also now feasible to transduce hES-CD34 cells with anti-HIV genes such as inhibitory siRNAs and test their antiviral efficacy in down stream differentiated cells such as macrophages which are among the primary cells that need to be protected against HIV-1 infection. Thus, the potential utility of hES derived CD34 hematopoietic cells for HIV-1 gene therapy can be evaluated.
