Fundamentals of Biomedical Applications of Biomorphic SiC (2011)

In recent years, silicon carbide (SiC) has become an increasingly important material in numerous applications including high frequency, high power, high voltages, and high temperature devices. It is used as a structure material in applications which require hardness, stiffness, high temperature strength (over 1000° C), high thermal conductivity, a low coefficient of thermal expansion, good oxidation and corrosion resistance, some of which are characteristic of typical covalently bonded materials. It seems that SiC can create many opportunities for chemists, physicists, engineers, health professional and biomedical researches (Presas et al., 2006; Greil, 2002; Feng et al.2003). Silicon carbides are emerging as an important class of materials for a variety of biomedical applications. Examples of biomedical applications discussed in this chapter include bioceramic scaffolds for tissue engineering, biosensors, biomembranes, drug delivery, SiC-based quantum dots and etc. Although several journals exist that cover selective clinical applications of SiC, there is a void for a monograph that provides a unified synthesis of this subject. The main objective of this chapter is to provide a basic knowledge of the biomedical applications of SiC so that individuals in all disciplines can rapidly acquire the minimal necessary background for research. A description of future directions of research and development is also provided.
Functional outcome of tension band wiring in transverse fracture of medial malleolus (2021)

Background and Objectives: Medial malleoli fracture is one of the common fractures in ankle joint mainly due to road traffic accident in which transverse fracture of medial malleolus accounts for significant morbidity and mortality. Tension band wiring (TBW) is an accepted modality of treatment which enables early mobilization of the patients than any other methods of treatment at present. TBW converts a tensile force into compressive force there by improves fracture healing, early mobilization and improved functional outcome of medial malleoli fracture of ankle joint.Materials and Methods: A longitudinal cohort study of transverse fracture of medial malleolus requiring surgical treatment, 20 patients were selected by convenient sampling technique and were operated by tension band wiring technique. In our study we use Lauge- Hansen classification pronation –abduction and pronation- eversion type, patients were evaluated for functional outcome by using American Orthopaedic Foot and Ankle Society (AOFAS) Ankle – Hind foot scale. All data were analyzed using SPSS software v 20.0.Results: The result of our study shows the effectiveness of the procedure for medial malleolus where good to excellent results were obtained in 75% of cases, fair results were in 15% of cases and poor results in 10%.Conclusion: TBW is a simple, inexpensive technique and effective means of fixing medial malleolus fracture based on biomechanical principle with minimum complications. Long term complications of prolonged immobilization like joint stiffness, muscle wasting, pressure sores and osteoporosis are avoided. TBW for medial malleolus helps by achieving compression at fracture site, the fracture heals faster and helps in early rehabilitation.
Effects of Benzodiazepine and Pilocarpine on Rat Parotid Glands: Histomorphometric And Sialometric Study (2009)

Benzodiazepines are among the most frequently prescribed drugs and are often related with dry mouth. Pilocarpine is a cholinergic agonist that increases salivary flow rate and has been used to treat xerostomia. This study aimed to measure salivary flow rate of rats under chronic treatment with benzodiazepine (Diazepam), to analyze by histomorphometry the effects of the drug in the parotids glands and to verify the effect of the pilocarpine in glandular parenchyma and in the salivary flow rate. Seventy-two male Wistar rats were allocated to four groups. Control groups received saline during 60 days (C60) and pilocarpine (Pilo) during 60 days. Experimental groups were dealt with Diazepam associated with saline (DS), and Diazepam associated with pilocarpine (DP) during 60 days. The stimulated salivary flow rate was obtained by using the gravimetric method. After the animals were killed, parotid glands were removed and mass and size were determined. The specimens were processed and stereological analysis revealed cell volume. Mean values of size and salivary flow rate varied from 9.007 mm and 0.015 mg/min in DS to 7.854 mm and 0.029 mg/min in DP, respectively. ANOVA showed statistically significant differences between groups for size (p=0.0028) and salivary flow rate (p=0.0003). Psychotropic drugs caused hyposalivation in rats and acinar hypertrophy in their parotid glands. Pilocarpine, a cholinergic agonist with topical appliance, showed significant secretagogue action in the treatment of hyposalivation induced by Diazepam chronic use.
A Review of In-Situ Air Sparging for the Remediation of VOC-Contaminated Saturated Soils and Groundwater (1995)

In-situ air sparging is a developing remediation technique that has significant potential for use in VOC-contaminated saturated soils and groundwater. This technique consists of injecting air below the contaminated area to partition the dissolved, sorbed and free phase VOCs into the gas phase and to enhance the aerobic biodegradation of the VOCs. Because of the buoyancy effect, the VOCs in the gas phase are transported by air to the vadose zone where they are removed and subsequently treated by a soil vapor extraction system. Currently, the design, operation, and monitoring of air sparging systems is based mainly on an empirical approach with limited field experience. Extreme care must be exercised in designing and implementing the air sparging system so that the contaminants are removed efficiently and without adverse effects on the subsurface environment, particularly the spread of the contaminants to the clean areas. The current state of knowledge is inadequate for the design of effective air sparging systems which also prevent the spreading of contaminants into the clean areas. This paper first outlines the fundamentals of air sparging and then presents an overview of previous air sparging field and laboratory investigations. The paper then details a critical assessment of modeling studies which predict contaminant transport during the air sparging process. Finally, the paper outlines an on-going comprehensive research program that involves developing the most efficient and economical air sparging systems. This research program, which is being conducted at the University of Illinois at Chicago (UIC), includes performing laboratory aquifer simulation tests to characterize the basic mechanisms of air sparging, developing a contaminant transport model to optimize the different design variables in a typical air sparging system, and conducting a field demonstration of the optimal air sparging system.
Convergence properties of a decentralized Kalman filter (2008)

We consider the problem of decentralized Kalman filtering in a sensor network. Each sensor node implements a local Kalman filter based on its own measurements and the information exchanged with its neighbors. It combines the information received from other sensors through using a consensus filter as proposed in [14]. For a time-invariant process and measurement model, we show that this algorithm guarantees that the local estimates of the error covariance matrix converge to the centralized error covariance matrix and that the local estimates of the state converge in mean to the centralized Kalman filter estimates. However, due to the use of the consensus filter, the local estimates of the state do not converge to the least-squares estimate that would be obtained from a centralized Kalman filter.
Molecular Engineering of Triphenylamine Based Aggregation Enhanced Emissive Fluorophore: Structure-Dependent Mechanochromism and Self-Reversible Fluorescence Switching (2016)

Triphenylamine (TPA), a propeller-shaped optoelectronic molecule, has been used to generate stimuli-responsive smart fluorescent organic materials and correlate the effect of subtle structural changes on the molecular packing and mechanochromic fluorescence (MCF). The substituent (OCH3) position in the TPA phenyl ring and acceptors (malononitrile, cyanoacetamide, cyanoacetic acid, ethyl cyanoacetate, and diethylmalonate) strongly influenced the solid state and mechanochromic fluorescence as well as the molecular packing. The structure–property studies revealed that (i) TPA derivatives without the OCH3 substituent exhibit strong fluorescence (Φf = 85% (TCAAD-1, 55% (TDEM)), (ii) higher dihedral angle (τ) between donor (aminophenyl) and acceptor lead to weak/non fluorescent material, (iii) substituent at the ortho position to acceptor increased the dihedral angle (τ = 26.49 (TCAAD-2), τ = 27.14 (TDMM)), and (iv) the increase of alkyl groups produced self-reversible high contrast off-on fluorescence switching materials (TDEM). Powder X-ray diffraction studies indicate that stimuli induced reversible phase transformation from crystalline to amorphous and vice versa was responsible for fluorescence switching. The computational studies also supported that OCH3 substitution at ortho to acceptor increased the dihedral angle and optical band gap. Thus, the present studies provide a structural insight for designing TPA based organic molecules for developing new smart organic materials.
View-invariant alignment and matching of video sequences (2003)

In this paper, we propose a novel method to establish temporal correspondence between the frames of two videos. 3D epipolar geometry is used to eliminate the distortion generated by the projection from 3D to 2D. Although the fundamental matrix contains the extrinsic property of the projective geometry between views, it is sensitive to noise. Therefore, we propose the use of a rank constraint of corresponding points in two views to measure the similarity between trajectories. This rank constraint shows more robustness and avoids computation of the fundamental matrix. A dynamic programming approach using the similarity measurement is proposed to find the nonlinear time-warping function for videos containing human activities. In this way, videos of different individuals taken at different times and from distinct viewpoints can be synchronized. A temporal pyramid of trajectories is applied to improve the accuracy of the view-invariant dynamic time-warping approach. We show various applications of this approach such as video synthesis, human action recognition, and computer aider training. Compared to state-of-the-art techniques, our method shows a great improvement.

Diagnostic and genetic studies on fibrin-stabilizing factor with a new assay based on amine incorporation (1969)

Fibrinoligase, the fibrin cross-linking enzyme, transiently appearing during the course of coagulation in normal blood, was shown to catalyze the incorporation of a fluorescent amine, monodansylcadaverine [or N-(5-aminopentyl)-5-dimethylamino-1-naphthalene-sulfonamide] into casein. The reaction provided the basis of a sensitive fluorimetric method for measuring the activity of the enzyme (and also of similar other transpeptidases, such as transglutaminase). In tests involving plasma, certain difficulties had to be overcome which were mainly due to the fact that the enzyme itself does not occur in citrated plasma. Only its precursor (fibrin-stabilizing factor or factor XIII) is present, still requiring limited proteolytic activation by thrombin. Thus, in order to measure amine incorporation with plasma as a source of the factor, thrombin must be added. This necessitated a differential desensitization of the intrinsic fibrinogen so that the latter could not clot and could not thereby interfere with amine incorporation. Also, the thrombin-inactivating capacity of plasma had to be saturated to enable full conversion of the factor to the transpeptidase. Concentrations of casein, monodansylcadaverine, calcium, and hydrogen ions were chosen to permit almost maximal velocity of amine incorporation. A linear relationship with regard to plasma concentration could be obtained only under such conditions. No similar assay is presently available for quantitatively evaluating fibrin-stabilizing factor levels in plasma.The amine incorporation test was applied to a clinical case of hereditary total fibrin-stabilizing factor deficiency. The effect of transfusion therapy was studied, and some of the patient's relatives were examined. Whereas a paternal aunt and uncle gave values well within the normal range, a brother and the mother proved to be partially deficient and could be considered as heterozygous carriers. The father appeared to have a reduced level of fibrin-stabilizing factor, though not quite as low as the other two relatives. Two infusions (1 liter each) of fresh normal plasma, administered about 26 hr apart, brought levels in the patient's plasma close to those found in the mother and brother. The corrective power of the transfusions, however, rapidly declined within 5-6 days. Futility of the last transfusion could be ascribed to the appearance of a neutralizing antibody directed against the precursor stabilizing factor, a serious complication. General diagnostic versatility and potential of the quantitative amine incorporation assay with plasma is discussed.
Ground-state phase diagram of the square lattice Hubbard model from density matrix embedding theory (2016)

We compute the ground-state phase diagram of the Hubbard and frustrated Hubbard models on the square lattice with density matrix embedding theory using clusters of up to 16 sites. We provide an error model to estimate the reliability of the computations and complexity of the physics at different points in the diagram. We find superconductivity in the ground state as well as competition between inhomogeneous charge, spin, and pairing states at low doping. The estimated errors in the study are below ${T}_{c}$ in the cuprates and on the scale of contributions in real materials that are neglected in the Hubbard model.

Enabling high performance deep learning networks on embedded systems (2017)

Deep learning is nowadays one of the most popular research topics in computer science. In recent years, the extensive application of convolutional neural network has made it become a new direction for the computer architecture research that is developing rapidly. Currently, there is a growing demand on off-line deploying deep learning network on top of embedded mobile systems. However, how to balance the limited computing and storage resources on embedded platforms, and the huge storage requirements with the increase of network complexity, has become the core problem of current research. In this paper, we explore the optimization technology to enable high-performance deep learning network for embedded systems from two aspects: the neural network design and the acceleration on embedded platforms. We focus on convolutional neural networks. First, we combine several technologies and propose a set of pruning mechanisms to save storage resources. We also explore the concept of block-wise sparsity. Second, from the perspective of mobile deployment, we propose a method to automatically select the optimal convolution/matrix multiplication approach based on the sparsity of the matrix and its sparse structure. Our experiments on NVIDIA TX1 show that our approach can be used together to promote each other and achieve the goal of improving the performance of computation while reducing the storage consumption.
Stereoscopic and autostereoscopic display systems (1999)

In this article, the requirements for 3D television are outlined, and the suitability of different display types are considered. A brief description of our own approach is offered, which suggests that the first generation of 3D television will be a two-image system comprising a pair of images directed to the appropriate viewers' eyes. This will be achieved by means of steering optics controlled by a head-position tracker.
Reconstruction of the 3D structure of a building from the 2D drawings of its floors (1999)

This article presents our first results in reconstructing the 3D structure of a building using primitives delivered by the analysis of the 2D architectural drawings of its floors. A set of features is extracted from the set of architectural symbols available for each floor. A graph of matching hypotheses between the most pertinent features of two consecutive floors is then constructed. A maximal clique detection algorithm supplies the best set of matches. The geometrical transformation allowing each floor to be aligned with respect to its lower floor is computed from the pairs of matching features. The final 3D model of the building is obtained by heaping the 3D models of the consecutive floors.
Accuracy of enteral syringes with commonly prescribed paediatric liquid medicines (2017)

Dosing was inaccurate when small volumes were used across all syringe sizes and brands. These reflect volumes used in clinical practice. Administration error could potentially be reduced by (1) clinicians using syringes appropriate to dosing volumes and (2) manufacturers revising formulation concentrations for drugs.
Design of a IGZO TFT-based GOA circuit for external compensation pixel circuits (2018)

In this paper, a high-performance gate driver on array circuit (GOA) was designed with top-gate typed TFTs to provide switching signals for external compensation pixel circuits. To testify the function of this GOA circuit, the circuit was placed in a AMOLED display. It is turned out that the proposed GOA circuit exhibited stable output signals with pulse width from 60μs to 3.6ms. It is obviously that the pulse width of 3.6ms could meet the requirement of switching signals in external compensation pixel circuits. Moreover, the bottom gates bias of TFTs in GOA circuit could be adjustable by a external voltage source. Using a positive or negative bottom gate bias, the Vth of TFTs can be controllable to achieve a good output signal for GOA.

Optically detected multipulse nuclear-quadrupole-resonance studies of trivalent praseodymium in zero and weak static magnetic fields (1989)

Optically detected multipulse nuclear quadrupole resonance is used to study trivalent praseodymium in lanthanum trifluoride in zero and weak static magnetic fields. A spin-locking spin-echo rf pulse sequence consisting of a \ensuremath{\pi}/2 preparation pulse, followed by repeated sequence of space t, a \ensuremath{\pi}/2 pulse phase shifted by 90\ifmmode^\circ\else\textdegree\fi{} from the preparation pulse, and a space t. A Raman heterodyne scheme was used for optical detection. The coherence was observed to decay exponentially at a rate of 51 \ensuremath{\mu}sec (6.2 kHz) in zero static magnetic field. For static magnetic fields of 80 G applied along the ${c}_{3}$ axis the decay was described by time constants of 76 \ensuremath{\mu}sec (4.2 kHz) and 372 \ensuremath{\mu}sec (855 Hz). This represents a lengthening of the coherence time from a previously reported (two-pulse spin echo) 16.9 \ensuremath{\mu}sec (18.8 kHz) at zero field and a measured 37.5 \ensuremath{\mu}sec (8.5 kHz) at 80 G.
Statistical modelling for extreme observations in environmental engineering (1998)

Two statistical models of extreme observations are examined and recent developments on determination of the domains of attraction and selection of the largest observations are presented. The results are appropriate in cases where the actual sample size is very large and perhaps unknown. The use of the introduced methods is illustrated by two examples. © 1998 John Wiley & Sons, Ltd.

A prediction algorithm for feedback control models with long delays (2002)

It is well known that feedback control may be difficult in a network with long propagation delays (with large bandwidth-delay products). Various feedback-based congestion control algorithms considered for networks with long delays have been reviewed from control theoretical viewpoints. Most existing control algorithms are shown to provide a threshold-based control technique. However, as the propagation delay becomes significant, the past history over the entire time lag may have to be incorporated into the control strategy. An adaptive algorithm based on the optimal least mean square error technique is presented. The algorithm attempts to predict a future buffer size from the weight (slope) adaptation of unknown functions which are used for feedback control. Simulation results are presented, which show the effectiveness of the algorithm.
