Thermal Effects of Impaction Grafting in Proximal Humeral Hemiarthroplasty (2018)

Purpose:Tuberosity healing in hemiarthroplasty for proximal humerus fractures remains problematic. Improved implant design and better techniques for tuberosity fixation have not been met with improved clinical results. The etiology for tuberosity failure is multifactorial; however thermal injury to host bone is a known effect of using polymethylmethacrylate for implant fixation. We hypothesized that the effect of thermal injury at the tuberosity shaft junction could be diminished by utilizing an impaction grafting technique for hemiarthroplasty stems.Methods:Five matched pairs of cadaveric humeri were skeletonized and hemiarthroplasty stems were implanted in the proximal humeri in two groups. The first group had full cementation utilized from the surgical neck to 2 cm distal to the stem (cement group) and the second group had distal cementation with autologous cancellous bone graft impacted in the proximal 2.5 cm of the stem (impaction grafting group). Thermocouples were used to measure the inner cortical...
Automatic Counting Robot Development Supporting Qualitative Asbestos Analysis -Asbestos, Air Bubbles, and Particles Classification Using Machine Learning- (2010)

Asbestos, particle, and air bubble counting generally supports qualitative asbestos analysis, using such procedures as dispersion staining. Operators conventionally check and count asbestos fibers visually using a microscope - a difficult, time-consuming process. The microscopic observation robot we are automating to support qualitative asbestos analysis images fibers and saves them automatically to a database. In this paper, we introduce image processing method using machine learning to count asbestos, particles, and air bubbles automatically.

Multifunctional organic shockproof flexible sensors based on a composite of nickel phthalocyanine colourant, carbon nanotubes and rubber created with rubbing‐in technology (2021)

Abstract An organic multifunctional sensor based on a composite of nickel phthalocyanine colourant, multi‐walled carbon nanotubes and rubber is investigated in this work. The whole surface‐type device was fabricated over rubber substrate with rubbing‐in technology, including multi‐walled carbon nanotubes‐based electrodes. The proposed shockproof and flexible sensor is investigated in terms of its electric parameters, that is, its resistance and impedance, while varying the humidity (42%‐90% relative humidity), frequency (0.1‐200 kHz) and temperature (30‐68°C). The effect of each parameter is explained in depth to enhance the physics behind each outcome. The results demonstrate that impedance and resistance decrease with increases in temperature and humidity, while the sensitivity of the device decreases with an increase in frequency. These types of devices can be utilised by the medical industry for monitoring the humidity and temperature of patients while undergoing physiotherapy treatment.
Reactions of alkoxy radicals with O2. III. i‐C4H9O radicals (1985)

Abstract i ‐C 4 H 9 ONO was photolyzed with 366‐nm radiation at −8, 23, 55, 88, and 120°C in a static system in the presence of NO, O 2 , and N 2 . The quantum yield of i ‐C 3 H 7 CHO, Φ{ i ‐C 3 H 7 CHO}, was measured as a function of reaction of reaction conditions. The primary photochemical act is equation image and it proceeds with a quantum yield ϕ 1 = 0.24 ± 0.02 independent of temperature. The i ‐C 4 H 9 O radicals can react with NO by two routes equation image The i ‐C 4 H 9 O radical can decompose via equation image or react with O 2 via equation image Values of k 4 / k 2 ≃ k 4b / k 2 were determined to be (2.8 ± 0.6) × 10 14 , (1.7 ± 0.2) × 10 15 , and (3.5 ± 1.3) × 10 15 molec/cm 3 at 23 55, and 88°C, respectively, at 150‐torr total pressure of N 2 . Values of k 6 / k 2 were determined from −8 to 120°C. They fit the Arrhenius expression: For k 2 ≃ 4.4 × 10 11 cm 3 /s, k 6 becomes (3.2 ± 2.0) × 10 −13 exp{−(836 ± 159)/T} cm 3 /s. The reaction scheme also provides k 4b / k 6 = 3.59 × 10 18 and 5.17 × 10 18 molec/cm 3 at 55 and 88°C, respectively, and k 8b / k 8 = 0.66 ± 0.12 independent of temperature, where equation image
Stability and thermophysical properties test of carbide-derived carbon thermal fluid; a comparison between functionalized and emulsified suspensions (2020)

In this study, the stability and thermophysical properties of chemically functionalized and gum-Arabic emulsified carbide-derived carbon (CDC)/ water thermal fluids were investigated. The stability of the thermal fluids were studied through zeta potential measurements and imaging methods. The results indicated that functionalized-CDC has a higher stability than the emulsified-CDC. LAMBDA thermal conductivity analyzer, differential scanning calorimeter, and discovery hybrid rheometer were used to evaluate the thermal conductivity, heat capacity and viscosity of the suspensions, respectively. The results demonstrated that the thermal conductivity enhancement was independent of temperature, decreases with gum-Arabic concentration, and significantly enhanced with CDC loading with a maximum enhancement of 26.1% for 0.3 wt% functionalized CDC. Increasing the CDC loading was found to increase the viscosity and decrease the specific heat of the suspensions. Finally, correlation equations proposed for predicting the thermal conductivity and dynamic viscosity of the CDC-water suspension had R2 values of 0.90 and 0.81, respectively.
Electronic Flow Control and Roller Clamp Control in Intravenous Therapy (1980)

In a prospective clinical study, an electronic intravenous (IV) rate controller was compared with a standard roller clamp for control of IV infusions. The electronic IV rate controller was associated with fewer complications and more accurate fluid therapy than was the roller clamp. There was also a substantial savings of nursing time and a potential for cost savings when the electronic IV rate controller was used.
A Clinical Study of Facial Palsy (1981)

A consecutive series of 96 patients with facial palsy in the Department of Otolaryngology, Mie University Hospital was studied clinically during the two years from 1978 to 1979. There were 60 cases of Bell's palsy, 14 cases of Hunt's syndrome, 15 cases of posttraumatic palsy and 7 cases of intracranial vascular lesions and of head and neck malignancies. For the treatment of patients with Bell's palsy and Hunt's syndrome, peroral steroid and massive doses of intravenous ATP were used fundamentally and the following results were obtained.1. Seventy per cent of the patients with Bell's palsy and 42.9% of those with Hunt's syndrome were cured completely.2. The younger the patients were and the shorter the duration from the onset of disease to the start of treatment was, the higher the rate of complete cure.3. Several bizarre phenomena resulting from misdirected reinnervation, such as crocodile tears, synkinesis or twitching in the mimic muscles, were observed in 76.9% of the patients with incomplete cure.
Orthogonal projection of points in CAD/CAM applications: an overview (2014)

Abstract This paper aims to review methods for computing orthogonal projection of points onto curves and surfaces, which are given in implicit or parametric form or as point clouds. Special emphasis is place on orthogonal projection onto conics along with reviews on orthogonal projection of points onto curves and surfaces in implicit and parametric form. Except for conics, computation methods are classified into two groups based on the core approaches: iterative and subdivision based. An extension of orthogonal projection of points to orthogonal projection of curves onto surfaces is briefly explored. Next, the discussion continues toward orthogonal projection of points onto point clouds, which spawns a different branch of algorithms in the context of orthogonal projection. The paper concludes with comments on guidance for an appropriate choice of methods for various applications.
Adaptive equalization and data recovery in a dual-mode (PAM2/4) serial link transceiver (2004)

To achieve high bit rates link designers are using more sophisticated communication techniques, often turning to 4PAM transmission or decision-feedback equalization (DFE). Interestingly, with only minor modification the same hardware needed to implement a 4PAM system can be used to implement a loop-unrolled single-tap DFE receiver. To get the maximum performance from either technique, the link has to be tuned to match the specific channel it is driving. Adaptive equalization using data based update filtering allows continuous updates while minimizing the required sampler front-end hardware and significantly reduces the cost of implementation in multi-level signaling schemes. A transceiver chip was designed and fabricated in 0.13 /spl mu/m CMOS process to investigate dual-mode operation and the modifications of the standard adaptive algorithms necessary to operate in high-speed link environments.

Detection of a diastolic heart sound in children and young adults using high-frame-rate echocardiography (2022)

Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Colin"s Kids, Inc. PO Box 93 Hopewell, NJ 08525 Introduction The auscultatory finding of a fourth heart sound (S4) is clinically associated with a pathologic decrease in left ventricular compliance, but may be seen in healthy children by phonocardiography. High-frame-rate difference imaging (HFRDI) has demonstrated several propagating myocardial phenomena in the left ventricular (LV) lateral wall throughout the cardiac cycle, including during diastole. We hypothesize that these visualized wave phenomena correlate with physiologic and pathologic heart sounds. Purpose Using HFRDI, we sought to define the characteristics of a LV lateral wall late diastolic wave in healthy children and young adults. Methods HFRDI was obtained from the apical 4-chamber view with synchronized electrocardiogram (ECG) on the T5 system (Phased Array Research Scanner) acquiring images for this study between 587 and 1174 frames per second (depending on participant imaging characteristics). In addition, tissue Doppler images were acquired with synchronized ECG and phonocardiography (PCG) on a commercial ultrasound machine (Figure 1). Timing events were measured from the QRS onset on the ECG tracing. An S4 wave correlate was defined by meeting the following criteria: 1) occurring after the P wave on ECG; 2) at or after the onset of a’ on TDI; 3) occurring during the PCG S4; and 4) occurring prior to the S1 wave complex. The timing of the S4 wave in HFRDI was measured from the onset of QRS to the first appearance of the wave, and the wave velocity was calculated by measuring the length of the lateral wall and counting temporally calibrated image frames while the wave was visible. Results Nine healthy volunteers completed the imaging protocol with a median age of 20 years (range 6 – 22 years). A single, distinct late diastolic HFRDI wave was seen in all participants propagating from apex to base of the lateral LV free wall. This wave met the defined criteria to be a visual correlate of S4 in all participants. Measurements of correlated events are presented in Table 1. S4 propagating velocity was 2.96 ± 1.8 m/sec and occurred 25 ± 18 msec prior to the QRS onset. There is a strong positive correlation between age and S4 velocity [r(7) = 0.76, p = 0.019]. Conclusion The S4 heart sound can be reliably visualized by high frame rate imaging and has similar characteristics in healthy children and young adults. Further definition of normal and abnormal S4 wave characteristics may lead to a novel tool in defining LV diastolic function. Abstract Table 1 Abstract Figure 1
Crystallographic texture engineering through novel melt strategies via electron beam melting: Inconel 718 (2014)

Preliminary research has demonstrated the ability to utilise novel scan strategies in the electron beam melting (EBM) process to establish control of crystallographic texture within Inconel 718 deposits. Conventional EBM scan strategies and process parameters yield coarse columnar grains aligned parallel to the build direction. Through varying process parameters such as beam power, beam velocity, beam focus and scan strategy, the behaviour of the electron beam can be manipulated from a line source to a point source. The net effect of these variations is that the resulting crystallographic texture is controlled in a manner to produce either epitaxial deposits or fully equiaxed deposits. This research demonstrates the ability to change the crystallographic texture on the macroscale indicating that EBM technology can be used to create complex geometric components with both site-specific microstructures and material properties.

Automatic Segmentation Of Dermoscopy Images Using Histogram Thresholding On Optimal Color Channels (2011)

Automatic segmentation of skin lesions is the first step towards development of a computer-aided diagnosis of melanoma. Although numerous segmentation methods have been developed, few studies have focused on determining the most discriminative and effective color space for melanoma application. This paper proposes a novel automatic segmentation algorithm using color space analysis and clustering-based histogram thresholding, which is able to determine the optimal color channel for segmentation of skin lesions. To demonstrate the validity of the algorithm, it is tested on a set of 30 high resolution dermoscopy images and a comprehensive evaluation of the results is provided, where borders manually drawn by four dermatologists, are compared to automated borders detected by the proposed algorithm. The evaluation is carried out by applying three previously used metrics of accuracy, sensitivity, and specificity and a new metric of similarity. Through ROC analysis and ranking the metrics, it is shown that the best results are obtained with the X and XoYoR color channels which results in an accuracy of approximately 97%. The proposed method is also compared with two state-ofthe- art skin lesion segmentation methods, which demonstrates the effectiveness and superiority of the proposed segmentation method.
De novo discovery of mutated driver pathways in cancer (2011)

Next-generation DNA sequencing technologies are enabling genome-wide measurements of somatic mutations in large numbers of cancer patients. A major challenge in the interpretation of these data is to distinguish functional "driver mutations" important for cancer development from random "passenger mutations." A common approach for identifying driver mutations is to find genes that are mutated at significant frequency in a large cohort of cancer genomes. This approach is confounded by the observation that driver mutations target multiple cellular signaling and regulatory pathways. Thus, each cancer patient may exhibit a different combination of mutations that are sufficient to perturb these pathways. This mutational heterogeneity presents a problem for predicting driver mutations solely from their frequency of occurrence. We introduce two combinatorial properties, coverage and exclusivity, that distinguish driver pathways, or groups of genes containing driver mutations, from groups of genes with passenger mutations. We derive two algorithms, called Dendrix, to find driver pathways de novo from somatic mutation data. We apply Dendrix to analyze somatic mutation data from 623 genes in 188 lung adenocarcinoma patients, 601 genes in 84 glioblastoma patients, and 238 known mutations in 1000 patients with various cancers. In all data sets, we find groups of genes that are mutated in large subsets of patients and whose mutations are approximately exclusive. Our Dendrix algorithms scale to whole-genome analysis of thousands of patients and thus will prove useful for larger data sets to come from The Cancer Genome Atlas (TCGA) and other large-scale cancer genome sequencing projects.
Integrated Multi-Sensor System for Enhanced Space Surveillance - Design, Engineering, Integration and Tests (2006)

Space surveillance requires capabilities for detection, tracking, imaging and characterization of specific objects in space environment. In general, most current space surveillance systems are single-sensor based and are not capable of generating the desired tracking accuracy, and providing required object characterization. A suite of various types of the sensors that are spatially or temporarily separated may thus be used collectively to synthesize a composite, improved surveillance picture through fusion and post processing of retrieved data. However, this approach will not yield the highest possible data accuracy due to the errors introduced in correlation of location, orientation and detection time from different sensors. Furthermore, it may not provide timely surveillance data to the user and hence may degrade the utility of these data. In this paper, we present the architecture, operational concept and preliminary design of an advanced integrated multi-sensor system (AIMS) for enhanced space surveillance capability to alleviate these shortfalls. AIMS employs an active laser tracking and multiple spectral domain (visible and multi-band IR) sensing to provide high-resolution tracking, three-dimensional imaging and reliable characterization of space objects with down range resolution of 1 cm and velocity measurement accuracy of 1-10 cm/sec in near real-time. The engineering and integration of a scale-down prototype of AIMS together with results of initial field tests are reported in this paper. Issues, lessons learned, future development plan and potential application of AIMS to space missions will be discussed. 1.
Fetal and Neonatal Alloimmune Thrombocytopenia (2011)

Fetal and neonatal alloimmune thrombocytopenia constitutes the most common cause of severe thrombocytopenia in fetuses and neonates and of intracranial hemorrhage among term newborns. The cornerstone of therapy involves the use of steroids and intravenous immunoglobulins. Despite the risk of potentially devastating consequences to the fetus, fetal blood sampling has typically been used to document response to therapy. We propose a therapeutic algorithm based on risk stratification with individualized treatment optimization without the use of fetal blood sampling.
Design of RFQ Linac to Accelerate High Current Lithium Ion Beam from Laser Ion Source for Compact Neutron Source (2017)

Accelerator-driven compact neutron sources have been developed to conduct nondestructive inspection more conveniently and/or on the spot with lower cost than other neutron sources, such as spallation sources and nuclear reactors. In typical compact source, proton or deuteron are injected into Li or Be. To develop a higher flax source than conventional ones, we propose a source with 7Li beam generated by laser ion source using direct injection scheme (DPIS) into RFQ linac. Because of the higher velocity of center of mass than that in the case of proton beam injection, generated neutrons are more collimated. In addition, laser ion source with DPIS is expected to accelerate mA class fully ionized 7Li beam stably with simple setup, while it is difficult for conventional ion sources. The high collimation and high current are expected to lead to higher neutron flax. In this presentation, we present a design of RFQ linac optimized to accelerate such a high current beam with shorter distance.
Evaluation of brittle failures of polyethylene by subjection to biaxial stress (1962)

Abstract First and second order effects of density and melt index were found to be significant with stress level a significant factor in determining failure time using Maltese Cross shaped specimens. Stress and temperature had the greater influence on failure. Influence of temperature‐viscosity interaction is of concern along with transition in the mode of failure from ductile to brittle type. Reduction in the effect of melt index with increasing density is in accord with new theories on polyethylene crystal structure. It was also shown that higher modulus materials fail more rapidly.
Sucrose Synthetase from Phaseolus aureus Seedlings (1970)

Abstract Sucrose synthetase from mung bean (Phaseolus aureus) has been purified by a combination of ammonium sulfate precipitation, gel filtration, and sucrose density gradient centrifugation. The molecular weight of sucrose synthetase was determined to be about 106 by gel filtration chromatography and sucrose density gradient centrifugation. The density of the sucrose synthetase particle was determined by equilibrium sedimentation to be 1.20 g per cc. The ability to catalyze the synthesis of sucrose from each of the nucleoside diphosphate glucoses containing uridine, adenosine, thymidine, cytidine, and guanosine remains associated with the purified particle. Attempts to subdivide the particle into catalytically active units have been unsuccessful. The Michaelis constants of the substrates for the sucrose synthetase particles and the maximum velocities of sucrose synthesis in the presence of each of the nucleoside diphosphate glucoses have been determined. In competition experiments between pairs of nucleoside diphosphate glucoses, uridine diphosphate glucose inhibits the synthesis of sucrose from the other nucleoside diphosphate glucoses far more effectively than would be expected on the basis of competition between the substrates for the same catalytic sites. On the other hand, the adenosine-, thymidine-, cytidine-, and guanosine-containing nucleoside diphosphate glucoses do not inhibit sucrose synthesis from uridine diphosphate glucose as effectively as would be anticipated on the basis of a simple competition mechanism. It is concluded that uridine diphosphate glucose is able to control the synthesis of the other nucleoside diphosphate glucoses from sucrose by causing a modification of sucrose synthetase.
