Probabilistic visual recognition of artificial landmarks for simultaneous localization and mapping (2004)

Probabilistic robotics most often applied to the problem of simultaneous localisation and mapping (SLAM), requires measures of uncertainty to accompany observations of the environment. This paper describes how uncertainty can be characterised for a vision system that locates coloured landmarks in a typical laboratory environment. The paper describes a model of the uncertainty in segmentation, the internal cameral model and the mounting of the camera on the robot. It explains the implementation of the system on a laboratory robot, and provides experimental results that show the coherence of the uncertainty model.
<sup>131</sup>I-MIBG with myeloablative chemotherapy for neuroblastoma: A New Approaches to Neuroblastoma Therapy (NANT) phase I study (2005)

8505 Background: To determine the maximum tolerated dose (MTD) and toxicity of 131I-MIBG with CEM (carboplatin, etoposide, melphalan) and autologous transplant (AT). Methods: 24 children age 1.5–16.9 years with refractory MIBG+ neuroblastoma and no prior AT were entered; 22 were evaluable for toxicity and response. 131I-MIBG was given on day 0, CEM days 14 to 17 (doses reduced for GFR<100), and AT on day 21. 131I-MIBG was escalated in a 3+3 Phase I trial design, stratified by GFR. Results: Dose limiting toxicity (DLT) occurred in 1/6 patients at 12 mCi/kg of 131I-MIBG with Grade 4 hypotension, hypoxia, and acidosis after 131I-MIBG alone, due to bulky tumor, with death prior to CEM. At 15 mCi/kg, 0/3 patients had DLT initially and 2/3 had DLT when the level was expanded, for 2/6 DLT: 1 mucositis with intubation, and 1 veno-occlusive disease (VOD), with recovery. At 18 mCi/kg, there were 2/4 DLT: 1 sepsis that resolved and 1 toxic death from multi-organ failure. The MTD for normal GFR was Level 1 with 12 mCi/kg 131I-MIBG, carboplatin 1500 mg/m2, etoposide 1200 mg/m2, and melphalan 210 mg/m2. In the low GFR cohort, the initial dose level using 12 mCi/kg of MIBG had 1/6 DLT with VOD. Four more patients had VOD that did not reach DLT. A dose reduction for this group was proposed, so the MTD for the low GFR cohort was not finalized. The median whole body radiation dose was 211 cGy (range 111–307). All evaluable patients engrafted: median time for neutrophils >500, 10 (range 8–15) days, and for platelets>20,000, 26.5 (range 10–224) days. Six of 22 patients had complete or partial response at day 56 post-AT. Nine patients improved by MIBG scan, with median relative MIBG score of 0.4 (0–0.9). The event-free survival for all patients at 2 and 3 years is 0.41 and 0.28 ±0.11; survival at 3 years is 0.57±0.11, with median follow up of 34.3 months. Conclusions: The combination of 131I-MIBG with myeloablative chemotherapy is tolerable and effective for resistant neuroblastoma. No significant financial relationships to disclose.
A System to Generate Patient-Specific Stimuli for use with the Auditory Brainstem Response Test (2007)

The short-pulsed "click" stimuli most commonly used to evoke an Auditory Brainstem Response (ABR) do not account for temporal shifts along the basilar membrane and do not produce ABRs of maximal amplitude. This paper describes a system that maps these temporal shifts and generates patient-specific stimuli to compensate. This is of interest both to enhance the ABR and as a potential way to map the physiology of the basilar membrane.

<title>Watermark copy attack</title> (2000)

Research in digital watermarking has progressed along two paths. While new watermarking technologies are being developed, some researchers are also investigating different ways of attacking digital watermarks. Common attacks to watermarks usually aim to destroy the embedded watermark or to impair its detection. In this paper we propose a conceptually new attack for digitally watermarked images. The proposed attack does not destroy an embedded watermark, but copies it from one image to a different image. Although this new attack does not destroy a watermark or impair its detection, it creates new challenges, especially when watermarks are used for copyright protection and identification. The process of copying the watermark requires neither algorithmic knowledge of the watermarking technology nor the watermarking key. The attack is based on an estimation of the embedded watermark in the spatial domain through a filtering process. The estimate of the watermark is then adapted and inserted into the target image. To illustrate the performance of the proposed attack we applied it to commercial and non-commercial watermarking schemes. The experiments showed that the attack is very effective in copying a watermark from one image to a different image. In addition, we have a closer look at application dependent implications of this new attack.
Spiking Neural Controller for Autonomous Robot Navigation in Dynamic Environments (2020)

In this paper, a neural controller based on Spiking Neural Network (SNN) is trained using the Reward-modulated Spike-Timing-Dependent Plasticity (R-STDP) learning approach for the tasks of simultaneous target tracking and obstacle avoidance. The neural controller has two separate layers with a fully connected architecture. A random number vector encodes the sensor data within the network, and its output is obtained by calculating the membrane potential of the output layer. The SNN is connected to a 2 DoF robotic arm with two degrees of freedom and to control the motors. Two moving objects are used as targets and obstacles. The results showed that the network is able to distinguish between two objects in the environment. After learning, the robot found the proper path to reach the target without colliding the obstacle.
NovAtel's RT20 - A Real Time Floating Ambiguity Positioning System (1994)

Over the past 10 years, the thrust of many GPS
programs has been towards solving the precise
positioning problem with a fmed integer carrier
solution. Progress has been made in this area, but an
uncertain multipath environment and decorrelated
ionospheric delays have made this technology
problematic for a single frequency receiver. The
nature of the solution requires an excess of
computing resources and a lot of time, if special
initialization methods are not used. NovAtel has
developed a high performance floating ambiguity
differential positioning package on a single board
which promises to be as robust as a differential
pseudorange system but approaches the accuracy
achievable with a f&d ambiguity single frequency
system. The process is described in this paper,
including its features, data stream, positioning filters
and test methods and results.
Preoxidation cleaning optimization for crystalline silicon (solar cell manufacture) (2002)

A series of controlled experiments has been performed to evaluate the effect of various chemical surface treatments on the recombination lifetime of crystalline silicon solar cell wafers subjected to high temperature dry oxidation. From this series of experiments, a relatively simple, yet effective, cleaning sequence is deduced. Also evaluated is the effect of different chemical damage-removal etches for improving the recombination lifetime and surface smoothness of mechanically lapped wafers. The methodology used, the experimental results obtained, and the authors' experience using this process on a continuing basis over a period of many months are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tantalum Aluminum Alkoxide as a Double-Metal Precursor for Metalorganic Chemical Vapor Deposition of Sr<sub>2</sub>AlTaO<sub>6</sub> (2001)

We proposed resolving the poor controllability in the metalorganic chemical vapor deposition (MOCVD) of a complex oxide film consisting of a few metal elements, Sr 2 AlTaO 6 (SAT) film, by using a double-metal source, tantalum aluminum isopropoxide TaAl(O–iC 3 H 7 ) 8 . It had a melting point as low as 93°C and generated suitable vapor pressure for MOCVD at a temperature of 100°C. The supply metal ratio, Al/Ta, was ∼1, because it remained a double-metal structure in the vapor phase. We grew stoichiometric SAT films using it as a metal source.
Highly Accelerated Parallel Imaging Methods for Localized Massive Array Coils: Comparision Using 64-Channel Phased-Array Data (2006)

Massive parallel phased-array systems with 32, 64, or more receive channels have potential to achieve high scan time saving for parallel MRI. In the past decade, a number of parallel MRI methods have been proposed including SENSE, SMASH, PILS, GRAPPA, SPACE-RIP, SEA, and other methods. In this work, we investigate the optimality of four reconstruction methods for parallel imaging with massive localized linear phased-array coils. In particular, the artifact power, SNR, and scan efficiency of different methods are systematically compared and analyzed. The studies are based on real MR data collected using a 64-channel system for 2-D MR imaging. The results show that the auto-PILS method and the improved GRAPPA method provide the best SNR and minimal artifact. In addition, the auto-PILS method is most efficient in scan time reduction. Interestingly, SMASH is not optimal for use with the highly localized coils with coil width on the same order as the voxel size.
The Impact of Electronic Disks on System Architecture (1975)

The availability of mass storage devices with access times several orders of magnitude less than rotating-device memories will have varying impacts on computer system architectures. These effects will range from simple changes such as direct substitution for disks, where significant productivity increases can be easily achieved, through more radical changes where both hardware and software are changed in structure to exploit the potential of these new devices. Such changes include architectures for transaction-based computing, real-time computing with nonresident programs, and more flexible structures for time-shared computers.
Numerical calculation model for spin-dependent transport of photoexcited electrons across Fe/GaAs(0 0 1) interfaces (2010)

Spin-dependent transport of photogenerated electrons across Fe/GaAs(0 0 1) interfaces is calculated using a one-dimensional electron transport model. Creation of spin-polarized electrons by photoexcitation in this model is defined by the band structure of GaAs along the [0 0 1] direction and the optical selection rules. The tunnel probability across the interface is obtained from Chang's model and first principles calculations are employed to calculate the spin polarization of Fe for electrons propagating along the [0 0 1] direction. By combining the above ingredients, the spin-filtering current, I SF , was calculated for different parameter values, including Schottky barrier height and photon energy. The model is used to fit with experimental results of the photoexcitation technique, yielding qualitative agreement especially for the observed sign switching of the spin-filtering current.
Changes in the subunit distribution of prosomes (MCP-proteasomes) during the differentiation of human leukemic cells (1997)

The subunit composition of cell-internal and surface prosomes during phorbol myristate acetate (PMA)-induced differentiation of human leukemic T lymphocytes (CCRF-CEM cell line) was studied in relation to clusters of differentiation (CD) markers. PMA inhibited cell growth and decreased the amounts of CD1a and CD4 while CD3, CD8, CD25, CD45, CD57 and MHCI increased it; the p53 anti-oncogene increased while actin levels remained constant. Cells incubated with the inducer PMA for 3 days and placed in fresh inhibitor-free medium resumed growth at a low rate, while the CD values slowly reverted to those of the initial phenotype. The presence and relative amounts of prosome subunits were analyzed by flow cytometry, light and fluorescent microscopy and Western blotting using 3 monoclonal antibodies (p25K, p27K and p30-33K MAbs). The decrease in cytoplasmic antigens on day 3 was remarkable (cells followed for 7 days) while increased surface antigens were observed. Changes in the subcellular distributions of prosome antigens, particularly the p25K and p30-33K subunit, were correlated with a partial arrest of the cell cycle. Interestingly, the composition of cell internal and surface prosomes showed different patterns of change.

Imaging Reveals Optic Tract Degeneration in Hemianopia (2010)

Transsynaptic degeneration had already begun 18 months after lesion. Although there was no visible decrease in volume at this stage, the white matter integrity was compromised. Significant decrease in volume could be visualized at longer durations of hemianopia. This method of objectively assessing structural images provides an effective, noninvasive approach to monitor the timescale of optic tract degeneration.

Diagnostic and therapeutic utility of B-type natriuretic peptide in patients with renal insufficiency and decompensated heart failure. (2003)

Chronic kidney disease (CKD) and congestive heart failure (CHF) are epidemiologically and pathophysiologically linked. A recent study in patients with severe CHF demonstrated that renal plasma flow was inversely correlated with pulmonary capillary wedge pressure, right atrial pressure, pulmonary pressure, and right ventricular ejection fraction. This article reviews the utility of B-type natriuretic peptide (BNP) levels in assessing cardiac function and volume status in patients with CKD and examines the safety and efficacy of BNP therapy in patients with renal insufficiency and decompensated heart failure.
Copper-Based Olefin Polymerization Catalysts: High-Pressure <sup>19</sup>F NMR Catalyst Probe (2003)

Reports of nickel and palladium bisimine catalysts and, more recently, iron and cobalt tridentate catalysts has spurred the research in late transition metal catalyzed polymerizations. The polymerization of ethylene with nickel and palladium imine catalysts has generally yielded substantial branching in the polyethylenes produced. The more recent reports indicated that cobalt and iron catalysts produced far fewer branches in the polyethylenes yielded. We report the polymerization of ethylene using copper bisbenzimidazole catalysts that produce very highly linear polyethylene with the ability to incorporate certain a-olefins. High Pressure 19F NMR studies suggest that these copper based systems act as single-site polymerization catalysts for ethylene and α-olefins.
A synthetic system that senses <i>Candida albicans</i> and inhibits virulence factors (2018)

Abstract Due to a limited set of antifungals available and problems in early diagnosis invasive fungal infections caused by Candida species are among the most common hospital-acquired infections with staggering mortality rates. Here, we describe an engineered system able to sense and respond to the fungal pathogen Candida albicans , the most common cause of candidemia. In doing so, we identified hydroxyphenylacetic acid (HPA) as a novel molecule secreted by C. albicans . Furthermore, we engineered E. coli to be able to sense HPA produced by C. albicans . Finally, we constructed a sense-and-respond system by coupling the C. albicans sensor to the production of an inhibitor of hypha formation thereby reducing filamentation, virulence factor expression and fungal-induced epithelial damage. This system could be used as a basis for the development of novel prophylactic approaches to prevent fungal infections.
Characterization of zinc-binding sites in human stromelysin-1: stoichiometry of the catalytic domain and identification of a cysteine ligand in the proenzyme (1992)

A determination of the zinc stoichiometry of the catalytic domain of the human matrix metalloproteinase stromelysin-1 has been carried out using enzyme purified from recombinant Escherichia coli that express C-terminally truncated protein. Atomic absorption spectrometry revealed that both the proenzyme (prostrom255) and the mature active form (strom255) contained nearly 2 mol of Zn/mol of protein. Full-length prostromelysin purified from a mammalian cell culture line also contained zinc in excess of 1 equiv. While zinc in prostrom255 could not be removed by dialysis against o-phenanthroline, similar treatment of mature strom255 resulted in the loss of one-half of the original zinc content. The peptidase activity of the zinc-depleted protein was reduced by greater than 85% but could be restored upon addition of Zn2+ or Co2+. Addition of a thiol-containing inhibitor to a CoZn hybrid enzyme resulted in marked spectral changes in both the visible and ultraviolet regions characteristic of sulfur ligation to Co2+. This direct evidence for an integral role in catalysis and inhibitor binding confirms the location of the exchangeable metal at the active site. To examine the environment of zinc in the proenzyme, a fully cobalt-substituted proenzyme was prepared by in vivo metal replacement. The absorbance features of dicobalt prostrom255 were consistent with metal coordination by the single cysteine present in the propeptide, although the data do not allow assignment to a particular zinc site.(ABSTRACT TRUNCATED AT 250 WORDS)
Modified method of characteristics for solving population balance equations (2003)

Abstract This paper presents a new numerical method for solving the population balance equation using the modified method of characteristics. Aggregation and break‐up are neglected but the density function variations in the three‐dimensional space and its dependence on the external fields are accounted for. The method is an interpretation of the Lagrangian approach. Based on a pre‐specified grid, it follows the particles backward in time as opposed to forward in the case of traditional method of characteristics. Unlike the direct marching method, the inverse marching method uses a fixed grid thus, making it compatible with other numerical schemes (e.g. finite‐volume, finite elements) that may be used to solve other coupled equations such as the mass, momentum, and energy conservation equations. The numerical solutions are compared with the exact analytical solutions for simple one‐dimensional flow cases. Very good agreement between the numerical and the theoretical solutions has been obtained confirming the validity of the numerical procedure and the associated computer program.

Regulation of catechol synthesis in an adrenergic clone of mouse neuroblastoma (1974)

Publisher Summary This chapter discusses studies analyzing regulation of catechol synthesis in an adrenergic clone of mouse neuroblastoma. From the mouse neuroblastoma cell culture system, clones were derived which were examined for tyrosine hydroxylase, choline acetyltransferase and acetylcholinesterase. Three major types of clones were found (1) adrenergic, (2) cholinergic and (3) clones that do not synthesize acetylcholine or catechols (inactive). All major types of clones had high levels of acetylcholinesterase and electrically excitable membranes. Except for one inactive clone, all clones were able to form neurites. No clone had high levels of both choline acetyltransferase and tyrosine hydroxylase. The results showed that mouse neuroblastoma C1300 is a heterogeneous cell population comprising at least three cell types when classified with respect to neurotransmitter synthesis. To investigate the biosynthesis of catecholamines, the adrenergic neuroblastoma clone (NIE-115) with the highest level of tyrosine hydroxylase was studied. The activity of tyrosine hydroxylase in crude sonicates of N1E-115 is comparable to that found in lysed granules of the adrenal medulla which is regarded as a very rich source of this enzyme. This chapter reports results with N1E-115 on transport of neurotransmitter precursors and regulation of tyrosine hydroxylase.
Hepatic Visceral Larva Migrans of <i>Toxocara canis</i>: CT and Sonographic Findings (2006)

CT and sonographic findings of hepatic visceral larva migrans of T. canis are multiple, ill-defined, oval or elongated, small, nodular lesions scattered in the liver parenchyma. The presence of hepatic lesions on images was associated with higher peripheral eosinophil count and percentage.
In vivo distraction forces in extendible endoprosthetic replacement—a study of 34 patients (1998)

Using an instrumented distraction tool 34 extendible endoprosthetic replacements were lengthened to measure total resistance to extension. The study consisted of 19 distal femoral, 2 proximal femoral, 1 total femoral, 8 proximal tibial, 1 distal humeral, 2 proximal humeral and 1 total humeral replacements. Among these prostheses a total of 76 measurements were made. The initial load on the prosthesis due to soft tissues and muscles varied between 0 and 578 N with an overall mean of 128 N. There was a linear relationship between extension and load. At 6 mm extension the load varied between 42 and 1513 N with a mean of 476 N. There was very little difference between the means of femoral and tibial measurements. There was very little resistance to extension in the total humeral replacement due to the absence of glenoid and muscle attachment. In the distal humeral replacement all three measurements were comparable with the forces in proximal tibial replacements. Two cases showed very high resistance to extension, which was mainly attributed to the presence of large amounts of scar tissues observed at surgery. During one lengthening operation a 30 s pause at 1 mm increments from 0 to 9 mm showed load recovery of approximately 10 per cent for up to 3 mm, beyond which there appeared to be stiffening of tissues.
