Image Based Camera Localization: an Overview (2016)

Recently, virtual reality, augmented reality, robotics, autonomous driving et al attract much attention of both academic and industrial community, in which image based camera localization is a key task. However, there has not been a complete review on image-based camera localization. It is urgent to map this topic to help people enter the field quickly. In this paper, an overview of image based camera localization is presented. A new and complete kind of classifications for image based camera localization is provided and the related techniques are introduced. Trends for the future development are also discussed. It will be useful to not only researchers but also engineers and other people interested.
Functional Interaction between Nucleosome Assembly Proteins and p300/CREB-Binding Protein Family Coactivators (2000)

The p300/CREB-binding protein (CBP) family of proteins consists of coactivators that influence the activity of a wide variety of transcription factors. Although the mechanisms that allow p300/CBP proteins to achieve transcriptional control are not clear, it is believed that the regulation of chromatin is an important aspect of the process. Here, we describe a new level of p300-dependent control mediated through the functional interaction between p300/CBP and members of the family of nucleosome assembly proteins (NAP), which includes NAP1, NAP2, and TAF1. We find that NAP proteins, which have previously been implicated in the regulation of transcription factor binding to chromatin, augment the activity of different p300 targets, including p53 and E2F, through a process that is likely to involve the physical interaction between p300 and NAP. NAP proteins can form oligomers, and the results show that NAP proteins can bind to both core histones and p300 coactivator proteins, perhaps in a multicomponent ternary complex. We also provide data in support of the idea that histones can influence the interaction between p300 and NAP protein. These results argue that NAP is a functionally important component of the p300 coactivator complex and suggest that NAP may serve as a point of integration between transcriptional coactivators and chromatin.
HPA Axis Reactivity and Lymphocyte Glucocorticoid Sensitivity in Fibromyalgia Syndrome and Chronic Pelvic Pain (2007)

Our results suggest normal HPA responses to stress and ACTH stimulation in patients with CPP but reduced adrenal reactivity in patients with FMS, namely in total cortisol release. Free cortisol on the other hand was unaltered, possibly reflecting an adaptation to reduced circulating total cortisol.
A Study of the Regional Effects of α-Synuclein on the Organization and Stability of Phospholipid Bilayers (2006)

Associations between the protein alpha-synuclein (alpha-syn) and presynaptic vesicles have been implicated in synaptic plasticity and neurotransmitter release and may also affect how the protein aggregates into fibrils found in Lewy bodies, the cellular inclusions associated with neurodegenerative diseases. This work investigated how alpha-syn interacts with model phospholipid membranes and examined what effect protein binding has upon the physical properties of lipid bilayers. Wide line 2H and 31P NMR spectra of phospholipid vesicles revealed that alpha-syn associates with membranes containing lipids with anionic headgroups and can disrupt the integrity of the lipid bilayer, but the protein has little effect on membranes of zwitterionic phosphatidylcholine. A peptide, alpha-syn(10-48), which corresponds to the lysine-rich N-terminal region of alpha-syn, was found to associate with lipid headgroups with a preference for a negative membrane surface charge. Another peptide, alpha-syn(120-140), which corresponds to the glutamate-rich C-terminal region, also associates weakly with lipid headgroups but with a slightly higher affinity for membranes with no net surface charge than for negatively charged membrane surfaces. Binding of alpha-syn(10-48) and alpha-syn(120-140) to the lipid vesicles did not disrupt the lamellar structure of the membranes, but both peptides appeared to induce the lateral segregation of the lipids into clusters of acidic lipid-enriched and acidic lipid-deficient domains. From these findings, it is speculated that the N-terminal and C-terminal domains of full-length alpha-syn might act in concert to organize the membrane components during normal protein function and perhaps play a role in presynaptic vesicle synthesis, maintenance, and fusion.
Curve fitting algorithm using iterative error minimization for sketch beautification (2008)

In previous sketch recognition systems, curve has been fitted by a bit heuristic method. In this paper, we solved the problem by finding the optimal parameter of quadratic Bezier curve and utilize the error minimization between an input curve and a fitting curve by using iterative error minimization. First, we interpolated the input curve to compute the distance because the input curve consists of a set of sparse points. Then, we define the objective function. To find the optimal parameter, we assume that the initial parameter is known. Then, we derive the gradient vector with respect to the current parameter, and the parameter is updated by the gradient vector. This two steps are repeated until the error is not reduced. From the experiment, the average approximation error of the proposed algorithm was 0.946433 about 1400 synthesized curves, and this result demonstrates that the given curve can be fitted very closely by using the proposed fitting algorithm.
Decentralized asynchronous particle swarm optimization (2008)

In this article we discuss a decentralized totally asynchronous realization of the particle swarm optimization (PSO) algorithm, which is suitable for parallel implementation. The proposed method has important differences from the PSO implementations considered in the literature. In the proposed method the particles are allowed to exchange information and to update their estimates at totally independent time instants. Moreover, time delays during information exchange between particles (leading to use of outdated information) are also allowed. Furthermore, particle neighborhoods are allowed to dynamically change with time. We also provide a mathematical model of the proposed method based on results in the parallel and distributed computation literature. The performance of the proposed algorithm is tested using numerical simulations with benchmark functions.
Performance of Optical Mobile Communications with User Mobility and Multiple Light Sources (2021)

Optical mobile communication (OMC) is a recently proposed optical wireless communication concept aiming to provide very high‐speed data rate optical wireless links for multiple and, in general, distributed mobile users. Previous work analyzed the rate performance of a two‐user OMC system without user mobility. This paper extends the rate analysis to multiple users with mobility. The scenario of employing multiple light sources with possible user grouping is also considered. User mobility and multiple light sources lead to new challenges on the system design which are addressed for broadcast downlink communication in this work. Simulations show that user mobility decreases the rate, and the way of how to utilize multiple light sources has great impact on the performance. In particular, simultaneous power division usage of multiple light sources through user grouping and power allocation brings almost no gain as compared with the case of single light source. On the other hand, time division usage of multiple light sources is capable of compensating for the hardware deficiency and thus increasing the rate greatly. It is found that OMC is not only superior to the conventional scheme with nonadjustable channel gains but also outperforms free space optical scheme at high signal‐to‐noise ratio region.
Isolation and Characterization of BART-1: A Novel Balloon Angioplasty Responsive Transcript in Rat Carotid Arteries (1996)

In previous studies, differential display analysis of balloon angioplasty-damaged rat carotid arteries identified a temporally expressed partial cDNA termed RC9. This message is undetectable in undamaged vessels, reaches maximal levels 3 days post-procedure, and reduces to half-maximal expression by 14 days post angioplasty. Using RC9 to screen a cDNA library, we now report the isolation and characterization of a full-length clone, termed BART-1. BART-1 is 98% homologous to RC9 and shows the same mRNA expression pattern as RC9 in rat carotid arteries subject to balloon angioplasty. Northern analysis of various rat tissues reveals tissue specificity and possible differential processing. Neither the nucleic acid nor amino acid sequences demonstrate similarity to previously reported expressed sequences. Predicted amino acid analysis reveals two strongly hydrophilic and one hydrophobic region, suggesting a type II integral membrane protein. The cDNA sequence hybridized to genomic DNA from a variety of species, suggesting evolutionary conservation. Thus, BART-1 mRNA appears to represent an inducible, tissue-specific transcript encoding a putative integral membrane protein transiently expressed in response to vascular trauma.
AN ECONOMIC ANALYSIS OF THE ENVIRONMENTAL IMPACT OF HIGHWAY DEICING (1976)

The study involves an analysis of the cost of damages that result from the use of salt (sodium chloride and calcium chloride) on highways to melt snow and ice. A large literature search and several surveys were carried out in order to determine the types and extent of damages that have occurred. The report contains over 320 references. An in-depth analysis was performed on all of the data obtained. The major cost sectors examined were: Water supplies and health, vegetation, highway structures, vehicles, and utilities. For each of the sectors a cost estimate was developed. The total annual national cost of salt related damage approaches $3 billion dollars or about 15 times the annual national cost for salt purchase and application. While the largest costs result from damage to vehicles, the most serious damage seems to be the pollution of water supplies and the degradation of health which may result. It is particularly difficult to assign costs in this latter area and therefore the estimate may substantially understate the actual indirect costs to society.
Randomized redundant DCT (2015)

j In this paper, we propose an acceleration method for image denoising with a redundant discrete cosine transform (R-DCT). Image denoising is essential for image processing, and its efficiency is important for graphics applications. R-DCT with a hard-thresholding or shrinkage method can perform denoising while keeping detail textures. Moreover, the method is computationally efficient compared with state-of-the-art denoising methods, such as BM3D. The computational cost, however, is still insufficient for real-time processing; hence, we accelerate the method by using randomized subsampling of DCT patches. Experimental results show that our method can accelerate the processing while the degradation of denoising performance is a little.
Effect of glucose and glycine addition to cocoa mass before roasting on Maillard precursor consumption and pyrazine formation (2002)

Abstract Cocoa mass was treated with glucose and/or glycine before roasting. For glucose‐treated samples the reductions in reducing sugars and free amino acids were 41.1 and 56.9% respectively, whereas for glycine‐treated samples the respective reductions were 16.2 and 37.4%. The combination of glucose plus glycine treatment led to 39.0 and 48.9% reductions in reducing sugars and free amino acids respectively. For free amino acids the reductions in control and glucose‐treated samples were similar, 56.2 and 56.9% respectively, indicating that the added glucose did not significantly ( P < 0.05) influence the free amino acid uptake. When glycine was added, the consumption of free amino acids (37.4%) was lower than for the control and glucose treatments. When glucose and glycine were added, the reduction in free amino acids (48.9%) was lower than for the control and glucose treatments but higher than for the glycine treatment. Apparently, glycine addition inhibited the reducing sugar and free amino acid consumption, whereas glucose addition enhanced the reducing sugar and free amino acid consumption. The glucose plus glycine treatment was similar to the glycine treatment in the contents of 2,5‐dimethyl‐ and trimethylpyrazines. For 2‐methylpyrazine the value for glucose‐treated samples was lower than for control and glycine‐treated samples but almost equal to the value for the glucose plus glycine treatment. It is concluded that the addition of glucose and/or glycine does not affect pyrazine production. © 2002 Society of Chemical Industry
Genetic Variability in Pulmonary Physiological, Cellular, and Antibody Responses to Antigen in Mice (1999)

Wide differences among inbred mouse strains in susceptibility to develop components of asthmalike pulmonary changes would provide insights into the nature of the relationships among those components and set the stage for genetic approaches to their etiology. We therefore examined pulmonary pathophysiological and serum immunoglobulin (Ig)E responses in mice of 12 inbred strains sensitized intraperitoneally with ovalbumin (OVA) and repeatedly exposed to aerosolized OVA. One day after the last OVA exposure the intravenous methacholine (MCh) dose required to reduce lung conductance by 50% (ED(50)GL) in OVA-sensitized and exposed mice was reduced by 0 to 2.7-fold, compared with sham-sensitized mice, depending on the strain. In OVA-sensitized mice, bronchoalveolar lavage (BAL) eosinophils comprised from 3.3 +/- 3.1 (SD) to 91.2 +/- 5.0% of BAL cells and eosinophilic pulmonary inflammation varied from being nondetectable to widespread and severe. OVA-specific IgE concentrations ranged from less than 3 ng/ml to 455 ng/ml in different strains. Shifts in responsiveness correlated significantly with pulmonary eosinophilia among strains (r > 0.70, p < 0.001) but not with antigen-specific IgE levels (r = 0.55, p = 0.056). These results demonstrate that allergen- induced enhancement of cholinergic responsiveness, pulmonary eosinophil influx, and elevations of serum antigen-specific IgE levels are each genetically determined and are not always associated.
Bcl-2 Antisense Oligonucleotide Overcomes Resistance to<i>E1A</i>Gene Therapy in a Low HER2-Expressing Ovarian Cancer Xenograft Model (2005)

We are currently conducting clinical trials of E1A gene therapy for patients with ovarian cancer. The adenovirus type 5 E1A gene suppresses growth of ovarian cancer cells that overexpress HER-2/neu (HER2) and growth of some--but not all--that express low HER2. In HER2-overexpressing cells, suppression by E1A is predominantly by down-regulation of HER2, but the mechanism in low HER2-expressing cells is not fully understood. The adenoviral E1B protein has sequential and functional homology to Bcl-2 and prolongs the viability of adenovirus host cells by inhibiting E1A-induced apoptosis. Bcl-2 is overexpressed in ovarian cancer and participates in chemoresistance; we hypothesized that Bcl-2 inhibits E1A-induced apoptosis leading to resistance to E1A gene therapy. E1A suppressed colony formation of ovarian cancer cells that express low levels of Bcl-2 and HER2 (OVCAR-3 and OVCA 433), but enhanced colony formation in low HER2-, high Bcl-2-expressing ovarian cancer cells (2774 and HEY). Treating 2774 or HEY cells with antisense oligonucleotide Bcl-2 (Bcl-2-ASO) did not reduce cell viability. E1A combined with Bcl-2-ASO led to significant decreases in cell viability resulting from increased apoptosis relative to cells treated with E1A alone (P < 0.05). The increase in apoptosis was partly due to cytochrome c release and subsequently caspase-9 activation by Bcl-2-ASO. Finally, in an ovarian cancer xenograft model, treatment with Bcl-2-ASO did not prolong survival, but E1A plus Bcl-2-ASO did (P < 0.001). In conclusion, ovarian tumors overexpressing Bcl-2 may not respond well to E1A gene therapy, but treatment with a combination of E1A and Bcl-2-ASO may overcome this resistance.
Efficacy of Common Laboratory Disinfectants on the Infectivity of <i>Cryptosporidium parvum</i> Oocysts in Cell Culture (2002)

Nine liquid disinfectants were tested for their ability to reduce infectivity of Cryptosporidium parvum oocysts in cell culture. A 4-min exposure to 6% hydrogen peroxide and a 13-min exposure to ammonium hydroxide-amended windshield washer fluid reduced infectivity 1,000-fold. Other disinfectants tested (70% ethanol, 37% methanol, 6% sodium hypochlorite, 70% isopropanol, and three commercial disinfectants) did not reduce the infectivity after a 33-min exposure. The results indicate that hydrogen peroxide and windshield washer fluid or ammonium hydroxide disinfectant may be suitable laboratory disinfectants against C. parvum oocysts.
EMI reduction with near field coupling suppression techniques for planar transformers and CM chokes in switching-mode power converters (2013)

In switching-mode power converters, planar transformers are one of the most important near magnetic field sources and CM chokes is one of the most important victims. This paper first analyzes the near magnetic field distribution of planar transformers and the effects of near magnetic field couplings on CM chokes. Based on these analyses, three techniques to suppress near magnetic field coupling's effects on EMI noise are proposed. They include the optimization of the position and orientation of planar transformers, the reduction of near magnetic field of planar transformers with magnetic shielding and a stacked CM choke structure with external EMI magnetic field immunity. Experimental results show these techniques can successfully suppress the EMI resulted from near magnetic field couplings.
The architecture of a large associative processor (1970)

This paper will describe features of architectural significance to the segmentability of a processor; it is not intended to be a detailed description of a processor for Information Storage and Retrieval. We regret that the incorporation of some features cannot be defended here because of the length of this paper. They are presented in a report. We first state the types of problems to be processed. This will lead to the overall organization of the processor. In Information Storage and Retrieval, a processor should have the capability to store data which is formatted as ordered sets or unordered sets, and to retrieve all such sets having a specified subset. An unordered set search for a given subset S retrieves all sets containing S. An ordered set search for a given ordered subset S retrieves all ordered sets containing S. A string search for a given string S retrieves all ordered sets (strings) having a substring S. For example, if S = (s1, s2, s3) and S1 = (s1, a, s2, s3), S2 = (a, b, s1), s2, s3, c, d), S3 = (s2, s1, s3) and S4 = (s1, a, b, s2). Then an unordered set search for S would retrieve S1, S2, S3, an ordered set search for S would retrieve S1 and S2, and a string search for S would retrieve S2.
<title>Magnetostrictive sensors for the characterization of corrosion in rebars and prestressing strands</title> (1996)

The feasibility of characterizing the severity of corrosion in reinforcing bars and prestressing strands was investigated using the magnetostrictive sensor (MsS) technique and time-frequency analysis. Relatively high bandwidth elastic waves were generated and detected in these steel members using the MsS technique. The detected signals wee then analyzed for their dispersion characteristics and attenuation with time-frequency analysis. In both rebars and strands, the wave attenuation was found to increase with an increased degree of corrosion. Wave attenuation was found to increase significantly when strands and rebar were cast in concrete. Initial studies showed that low frequencies will be needed to operate over a significant distance in concrete.
Chloroaluminate Equilibria in AlCl[sub 3]-NaCl Melts (1972)

Equilibrium constants were calculated for reactions governing the species present at 175°C in molten mixtures of aluminum chloride and sodium chloride. The equilibria postulated pertain to formation of the complex ions , , and from , , and . The constants were derived from potentials exhibited by concentration cells of the type , , , and from vapor pressures over pure and molten mixtures. Measurements were made throughout the concentration range . The possibilities of using these concentration cells as high energy density batteries are considered.
Evidence for protonation in the human neutrophil formyl peptide receptor binding pocket (1993)

We have studied the interaction of a family of fluorescent formyl peptides with their receptor using spectrofluorometric and flow cytometric methods. The peptides contained four (CHO-Met-Leu-Phe-Lys-fluorescein), five (CHO-Met-Leu-Phe-Phe-Lys-fluorescein), or six (CHO-Nle-Leu-Phe-Nle-Tyr-Lys- fluorescein) amino acids. As observed in earlier studies, the fluorescent peptides containing four and five amino acids were quenched upon binding to the receptor, while the hexapeptide was not. While the degree of quenching of the bound tetrapeptide was largely unchanged, the quenching of the bound pentapeptide decreased with increasing pH over the range of pH 6.5-9.0. Ligand binding studies have shown that the mole fraction of tetrapeptide or pentapeptide bound in kinetic analysis markedly decreased with increasing pH as a consequence of increasing ligand dissociation rate constant. The dependence of the binding parameters for the hexapeptide on pH was much less pronounced. Over a pH range from pH 7.3 to 9.0, the hexapeptide showed little change in binding affinity, while the tetrapeptide and pentapeptide increased in Kd approximately 2.0- and 2.5-fold, respectively. These results indicate that the formyl peptide receptor binding pocket contains at least two microenvironments. The pH sensitivity of the pentapeptide quenching is consistent with a protonating environment, while the pH-independent quenching of the tetrapeptide may reflect aromatic stacking or a hydrophobic microenvironment. The pH-dependent ligand dissociation also suggests that the protonation in the pocket stabilizes ligand binding, which may indicate an alteration in the binding pocket structure. Protonation or hydrogen bonding of the pentapeptide may lead to even further stabilization of that ligand.
Charge carrier transport and recombination at the interface between disordered organic dielectrics (2001)

An analytic model of charge carrier hopping at the interface separating two disordered organic materials in organic light-emitting diodes (OLEDs) is formulated. It is shown that the rate of charge carrier injection across such an interface is much lower than the rate of first interfacial jumps, most of which are followed by return carrier jumps back into initially occupied sites. In OLEDs, the rate of injection across the interface determines the leakage current while the rate of radiative recombination is proportional to the first-jump rate. Therefore, the marked difference between the injection rate and the rate of first carrier jumps across the interface implies a much higher efficiency of carrier recombination at the interface than predicted by the conventional Langevin theory of recombination.
