Neo-osseous Flaps Using Demineralized Allogeneic Bone in a Rat Model (2000)

Surgical reconstruction with revascularized bone grafts can be compromised by donor tissue limitations and may be refined by prefabrication of compound neoflaps using bone substitutes. The principal suitability of demineralized allogeneic bone (DALB) slabs in fabricating neo-osseous flaps based on the inferior epigastric vascular system was studied and compared with neoflaps with autologous bone (AUB). In 45 rats, the histological pattern of bone formation in response to angiogenesis induced by vessel implantation was assessed, and characteristics of vascularization of the neoflap were studied microangiographically at 2, 4, 6, and 8 weeks. Histological techniques included decalcified and nondecalcified sections, as well as intravital polyfluorochrome labeling. Blood flow of the neoflap was also assessed quantitatively using 15-microm microspheres labeled with technetium 99-methylene diphosphate (99-MDP) 8 weeks after flap fabrication. Although the DALB neoflaps showed consistent bone formation and neovascularization, the bone regeneration process was delayed distinctly in comparison with AUB. Microangiographically, however, no differences between the two types of grafts became apparent during all time periods tested. Furthermore, the radioactivity of the DALB neoflap, which means bone blood flow per dry weight, was significantly higher than in AUB grafts and even more than that of intact iliac bone (p = 0.001). The exact meaning of elevated blood flow in DALB and similar degrees of vascularization corresponding to native AUB grafts remains to be determined, but may be a sign of ongoing bone formation resulting in a suitable DALB-containing neo-osseous flap in the long term. The authors findings support that allogeneic bone could be a potential substitute for AUB in creating a prefabricated neo-osseous flap.
Autofocusing algorithm of interferogram based on object image and registration technology (2013)

Because the depth of field (DOF) of lenses is limited, a captured interferogram usually includes a focused region and defocused region simultaneously when the form deviation of the helical tooth flank is measured with laser interferometry. Because of the impact of the interference fringe, the existing autofocusing algorithms are difficult for identifying the focused region of the interferogram directly. This paper proposes a new autofocusing algorithm based on the object image and registration technology. First, the reliability region is evaluated according to the gray level. Then the corresponding pixels in the image sequence are determined with the registration technology. Next, the focused region is judged by comparing the average gray gradients in object images. Based on the characteristics of measured gear and the DOF of lens, an experiment is designed. The experimental results are given to verify the feasibility and accuracy of the proposed autofocusing algorithm.
Advanced Steam Generators (2001)

Concerns about climate change have encouraged significant interest in concepts for ultra-low or ''zero''-emissions power generation systems. In some proposed concepts, nitrogen is removed from the combustion air and replaced with another diluent such as carbon dioxide or steam. In this way, formation of nitrogen oxides is prevented, and the exhaust stream can be separated into concentrated CO{sub 2} and steam or water streams. The concentrated CO{sub 2} stream could then serve as input to a CO{sub 2} sequestration process or utilized in some other way. Some of these concepts are illustrated in Figure 1. This project is an investigation of one approach to ''zero'' emission power generation. Oxy-fuel combustion is used with steam as diluent in a power cycle proposed by Clean Energy Systems, Inc. (CES) [1,2]. In oxy-fuel combustion, air separation is used to produce nearly pure oxygen for combustion. In this particular concept, the combustion temperatures are moderated by steam as a diluent. An advantage of this technique is that water in the product stream can be condensed with relative ease, leaving a pure CO{sub 2} stream suitable for sequestration. Because most of the atmospheric nitrogen has been separated from the oxidant, the potential to form any NOx pollutant is very small. Trace quantities of any minor pollutants species that do form are captured with the CO{sub 2} or can be readily removed from the condensate. The result is a nearly zero-emission power plant. A sketch of the turbine system proposed by CES is shown in Figure 2. NETL is working with CES to develop a reheat combustor for this application. The reheat combustion application is unusual even among oxy-fuel combustion applications. Most often, oxy-fuel combustion is carried out with the intent of producing very high temperatures for heat transfer to a product. In the reheat case, incoming steam is mixed with the oxygen and natural gas fuel to control the temperature of the output stream to about 1480 K. A potential concern is the possibility of quenching non-equilibrium levels of CO or unburned fuel in the mixing process. Inadequate residence times in the combustor and/or slow kinetics could possibly result in unacceptably high emissions. Thus, the reheat combustor design must balance the need for minimal excess oxygen with the need to oxidize the CO. This paper will describe the progress made to date in the design, fabrication, and simulation of a reheat combustor for an advanced steam generator system, and discuss planned experimental testing to be conducted in conjunction with NASA Glenn Research Center-Plumb Brook Station.
Learning to Predict Stereo Reliability Enforcing Local Consistency of Confidence Maps (2017)

Confidence measures estimate unreliable disparity assignments performed by a stereo matching algorithm and, as recently proved, can be used for several purposes. This paper aims at increasing, by means of a deep network, the effectiveness of state-of-the-art confidence measures exploiting the local consistency assumption. We exhaustively evaluated our proposal on 23 confidence measures, including 5 top-performing ones based on random-forests and CNNs, training our networks with two popular stereo algorithms and a small subset (25 out of 194 frames) of the KITTI 2012 dataset. Experimental results show that our approach dramatically increases the effectiveness of all the 23 confidence measures on the remaining frames. Moreover, without re-training, we report a further cross-evaluation on KITTI 2015 and Middlebury 2014 confirming that our proposal provides remarkable improvements for each confidence measure even when dealing with significantly different input data. To the best of our knowledge, this is the first method to move beyond conventional pixel-wise confidence estimation.
Competitive Algorithms for the Online Multiple Knapsack Problem with Application to Electric Vehicle Charging (2021)

We introduce and study a general version of the fractional online knapsack problem with multiple knapsacks, heterogeneous constraints on which items can be assigned to which knapsack, and rate-limiting constraints on the assignment of items to knapsacks. This problem generalizes variations of the knapsack problem and of the one-way trading problem that have previously been treated separately, and additionally finds application to the real-time control of electric vehicle (EV) charging. We introduce a new algorithm that achieves a competitive ratio within an additive factor of the best achievable competitive ratios for the general problem and matches or improves upon the best-known competitive ratio for special cases in the knapsack and one-way trading literatures. Moreover, our analysis provides a novel approach to online algorithm design based on an instance-dependent primal-dual analysis that connects the identification of worst-case instances to the design of algorithms. Finally, in the full version of this paper, we illustrate the proposed algorithm via trace-based experiments of EV charging.

The application of a VUV Fourier transform spectrometer and synchrotron radiation source to measurements of: I. The β(9,0) band of NO (1998)

State-of-the-art models of the vacuum ultraviolet (VUV) absorbing properties of the atmosphere call for absorption cross sections with detail on the scale of the Doppler widths. As a consequence, spectroscopic data at resolving powers of the order of 106 are needed. To meet these requirements in the vacuum ultraviolet region, we have used the VUV Fourier transform spectrometer from Imperial College, London, at the synchrotron radiation facility at Photon Factory, KEK, Japan, to measure photoabsorption cross sections of NO from 195 to 160 nm, and of O2 from 185 to 175 nm. The analysis of the β(9,0) band (B 2Πr–X 2Πr) of NO provides accurate rotational line positions and term values. Molecular constants of the B(9) 2Π level are T0=54 205.097±0.012 cm−1, A=45.320±0.021 cm−1, Bυ=1.016 72±0.000 16 cm−1, Dυ=(10.61±0.32)×10−6 cm−1, and AD=0.001 22±0.000 11 cm−1. The rotational line strengths and the branching ratios are also presented. The band oscillator strength is obtained as f=2.65×10−4.

Homocysteine, a risk factor for cardiovascular disease (2005)

Fasting hyperhomocysteinemia is an independent risk factor for coronary artery disease, stroke, peripheral vascular atherosclerosis, and for arterial and venous thromboembolism. The risk for cardiovascular disease with homocysteine is similar to conventional risk factors. The interaction of hyperhomocysteinemia with hypertension and smoking is strong and the combined effect is more than multiplicative. The combined effect of homocysteine and cholesterol is additive. Homocysteine produces atherosclerosis, thromboembolism, and vascular endothelial cell injury. Vascular dysfunction produced by homocysteine may be due to endothelial cell damage. Homocysteinemia-induced atherosclerosis is probably due to various factors including endothelial cell injury, inability to sustain S-nitroso-homocysteine formation because of imbalance between production of nitric oxide by dysfunctional endothelium and homocysteine, smooth muscle cell proliferation, and thromboembolism. There is strong evidence that endothelial cell injury is associated with oxidative stress produced by homocysteine. Hyperhomocysteinemia is associated with numerous conditions, including coronary disease, stroke, peripheral vascular disease (carotid artery and cerebrovascular atherosclerosis), venous thrombosis, renal disease, diabetes mellitus, and organ transplant. Folic acid, vitamin B12 and B6 have been shown to be beneficial in reducing plasma homocysteine levels. Folic acid is specifically very effective, safe and inexpensive.
Avoiding collision with hidden nodes in IEEE 802.11 wireless networks (2009)

In wireless networks, collision is a major factor of performance degradation. In this letter, we propose a scheme for reducing collision in IEEE 802.11 networks. Each node can avoid collision by maintaining a disjoint set of time slots for transmission. Through simulation, we show that the proposed scheme is effective to reduce collision even in the presence of hidden nodes.
Precise 1-V Curve Measurement Procedure for Perovskite Solar Cells: Application to Various Types of Devices (2017)

Precise performance measurement procedure for perovskite PV devices was applied to various types of cells. The study was focused on confirming the applicability and usefulness of the proposed measurement procedure by using devices prepared by different institutes. The procedure includes comparison of the 1-V curves at various sweep time, and evaluation of Pmax under a fixed voltage for precise characterization. The results indicated that the procedure is versatilely applicable to various types of perovskite solar cells, and precisely define the I-V curves and Pmax.
Backaction Cancellation in Quantum Nondemolition Measurement of Optical Solitons (1999)

Elimination efficiency of different reagents for the memory effect of mercury using ICP-MS (2005)

The present study was carried out to solve the problems of long washout time and non-linear calibration curves encountered in mercury analysis using inductively coupled plasma mass spectrometry. Comparisons of the washing efficiency for different reagents to eliminate the mercury memory effect were made. Of all the selected washing reagents, mercapto reagents such as 2-mercaptoethanol and L-cysteine could efficiently clean the instrument. Taking the toxicity and odor of mercaptoalkanol into account, L-cysteine was preferred as the most suitable washing reagent and was added into the standard and sample solutions. A good linear calibration curve was obtained with the correlation coefficient of 0.9999. The detetion limit for addition of L-cysteine was 0.024 μg l−1. Addition of 0.18% L-cysteine into the sample solution also facilitates the washout of mercury even using deionized water. The recoveries of mercury in certified reference materials, i.e. human hair and dogfish muscle, were 97.2% and 98.3%, respectively, when using 0.18% L-cysteine in the sample solutions.
Electrostatic Deposition of Aerosol Particles Generated from an Aqueous Nanopowder Suspension on a Chemically Treated Substrate (2010)

The state of electrostatically deposited aerosol particles from a suspension that contains TiO 2 particles on the surface of a solid substrate using electrospray was demonstrated. The particles were initially electrosterically stable in 7.5 wt % aqueous solution with a mean particle size of 50 nm. During deposition, the particles were pumped with different flow rates between 0.6 and 1.2 mL/h through a stainless steel capillary tube of 0.1 mm inner diameter. The particles were emitted at the tip of the capillary tube as an electrified liquid cone before forming into a highly charged droplet. For comparison, two types of substrate surfaces with and without chemical treatment were prepared. Atomic force microscopy (AFM) scanning and contact angle measurements showed that surface treatment increased the substrate roughness and created a hydrophilic surface. Raman analysis also showed the existence of an oxide layer and a P–O network on the treated substrate. Field emission scanning electron microscopy FE-SEM image analysis showed that more TiO 2 particles were deposited on the treated substrate than on the untreated substrate.

Evolution and computational intelligence (2002)

For over 40 years, efforts toward artificial intelligence have largely focused on emulating humans, either in their behavior or in their neurophysiology. This approach, despite many claims of success, or success that is just "within reach", has generally failed to produce any real evidence of machine intelligence, nor has it advanced our understanding of intelligence in general. Rather than to view humans as the premier example of intelligence, a broader and potentially more beneficial perspective approach is to view this species simply as a product of evolution, a process that generally produces organisms of increasing intellect. Recognizing the connection between evolution and intelligence makes it possible to overcome the limitations of conventional rule-based systems and neural network designs, and indeed to evolve such systems and create machine intelligence.
Investigation of correlation between surface current and coupling using conventional coils and shielded coaxial cable coils operating at 7T (2023)

One of the major challenges in the design of multichannel arrays for UHF MRI is minimizing coupling between elements. Shielded-coaxial-cable (SCC) coils have been recently proposed as highly decoupled elements per se: however, the decoupling mechanism of SCC coils is still not determined. In this work, we examined the relationship between coupling, surface current density uniformity, and the total current on coil conductor through measuring and simulating three different 2-coils arrays. While no correlation was observed between surface current density uniformity and interelement coupling, a negative correlation was observed between the coupling and the total current on coil conductor.

Blood Vessel Constitutive Models—1995–2002 (2003)

Knowledge of blood vessel mechanical properties is fundamental to the understanding of vascular function in health and disease. Analytic results can help physicians in the clinic, both in designing and in choosing appropriate therapies. Understanding the mechanical response of blood vessels to physiologic loads is necessary before ideal therapeutic solutions can be realized. For this reason, blood vessel constitutive models are needed. This article provides a critical review of recent blood vessel constitutive models, starting with a brief overview of the structure and function of arteries and veins, followed by a discussion of experimental techniques used in the characterization of material properties. Current models are classified by type, including pseudoelastic, randomly elastic, poroelastic, and viscoelastic. Comparisons are presented between the various models and existing experimental data. Applications of blood vessel constitutive models are also briefly presented, followed by the identification of future directions in research.
Complementary Circuits for On-Line Detection for 1-out-of-3 Codes. (2004)

In this paper a new method for concurrent checking of an arbitrarily given combinational multi-output circuit f by use of an 1-out-of-3 code is presented. The circuit f is completed by an additional multi-output circuit g in such a way that the XOR-sums of the corresponding outputs of f or of the inverted outputs of f and g are elements of a 1-out-of-3 code. For efficiently checking the 1-out-of-3 encoded outputs also a new self-checking checker based on a three-rail checker cell is proposed.
Diagnosis and management of patients with allergy to metal implants (2015)

Cutaneous allergic reactions to implanted metal devices, for example, orthopedic, are well reported in the literature. Also, extracutaneous complications resulting from peri-implant inflammation have been observed in association with metal allergy. Nickel, cobalt, and chromium are the three most common triggers of both cutaneous and extracutaneous allergy-related complications. However, the diagnosis of metal implant allergy remains a challenge, that is, the synopsis of excluding differential diagnoses and the combination of different allergy diagnostic tools is needed. Thus, the management of metal implant allergy is also hampered by clinical uncertainty and unresolved scientific questions.
