Investigation of Computational Compound-Eye Imaging System With Super-Resolution Reconstruction (2006)

Despite the emerging architectural designs of compound-eye imaging systems, the post-processing algorithms for the reconstruction of the final image from the multiple sub-images is still not fully developed to maturity, resulting in poor quality or low resolution of the reconstructed images. In this paper, we describe and investigate a practical computational compound-eye imaging system with super-resolution reconstruction. This methodology can enhance the image quality by increasing the resolution of the reconstructed image. A virtual compound-eye camera is built to demonstrate the feasibility of the system. Simulation results which investigate the tolerance of the system to lens diversity, for instance focal length and aberrations, are also presented.

Memory Augmented Neural Network Adaptive Controller for Strict Feedback Nonlinear Systems (2019)

In this work, we consider the adaptive nonlinear control problem for strict feedback nonlinear systems, where the functions that determine the dynamics of the system are completely unknown. We assume that certain upper bounds for the functions $g_i$s of the system are known. The objective of the control design is to design an adaptive controller that can adapt to changes in the unknown functions that are even abrupt. We propose a novel backstepping memory augmented NN (MANN) adaptive control method for the control of strict feedback non-linear systems. Here, each NN, in the backstepping NN adaptive controller, is augmented with an external working memory. The NN can write relevant information to its working memory and later retrieve them to modify its output, thus providing it with the capability to leverage past learned information effectively and improve its speed of learning. We propose a specific design for this external memory interface and show that the proposed control design achieves bounded stability for the closed loop system. We also provide substantial numerical evidence showing that the proposed memory augmentation improves the speed of learning by a significant margin.
Modular metrology tools for productivity enhancement in wafer fabs (1997)

Integrated metrology helps to reduce costs by decreasing the number of monitor wafers and by reducing the risk of wafer loss. For these reasons, there is an increasing demand for solutions which help to interface process control tools to manufacturing equipment in a cost-effective way. In this paper different measurement strategies are compared. A modular design of metrology tools is proposed enabling equipment vendors and sensor manufacturers to fast and easily integrate various metrology tools.
Algorithms for Bayesian Belief-Network Precomputation (1991)

Abstract Bayesian belief networks provide an intuitive and concise means of representing probabilistic relationships among the variables in expert systems. A major drawback to this methodology is its computational complexity. We present an introduction to belief networks, and describe methods for precomputing, or caching, part of a belief network based on metrics of probability and expected utility. These algorithms are examples of a general method for decreasing expected running time for probabilistic inference. We first present the necessary background, and then present algorithms for producing caches based on metrics of expected probability and expected utility. We show how these algorithms can be applied to a moderately complex belief network, and present directions for future research.
Adaptive transfer learning in deep neural networks: Wind power prediction using knowledge transfer from region to region and between different task domains (2019)

Abstract Transfer learning (TL) in deep neural networks is gaining importance because, in most of the applications, the labeling of data is costly and time consuming. Additionally, TL also provides an effective weight initialization strategy for deep neural networks. This paper introduces the idea of adaptive TL in deep neural networks (ATL‐DNN) for wind power prediction. Specifically, we show in case of wind power prediction that adaptive TL of the deep neural networks system can be adaptively modified as regards training on a different wind farm is concerned. The proposed ATL‐DNN technique is tested for short‐term wind power prediction, where continuously arriving information has to be exploited. Adaptive TL not only helps in providing good weight initialization, but also in utilizing the incoming data for effective learning. Additionally, the proposed ATL‐DNN technique is shown to transfer knowledge between different task domains (wind power to wind speed prediction) and from one region to another region. The simulation results show that the proposed ATL‐DNN technique achieves average values of 0.0637, 0.0986, and 0.0984 for the mean absolute error, root mean squared error, and standard deviation error, respectively.
Stimulation and antagonism of opioid !d-receptors produce opposite effects on active avoidance conditioning in mice. (1988)

The effects of opioid delta-receptor activation on conditioning in a one-way active avoidance paradigm were investigated in mice. Peripheral administration of 30 and 100 micrograms/kg of [Leu5]enkephalin (LE) and 11.6 micrograms/kg of [D-Pen2,D-Pen5]enkephalin (DPDPE), a synthetic enkephalin analog with high delta-selectivity, impaired acquisition of avoidance responding. The dose response functions for both peptides were U-shaped. Deficits in responding were also present 24 hours after training, which suggests that the impaired performance observed during training was not an impairment in the ability of the mice to perform. Also, neither LE nor DPDPE decreased footshock sensitivity or open-field activity, which rules out analgesia and decreased activity levels as likely explanations for the deficits in conditioning. Finally, antagonizing endogenous ligands with the delta-selective antagonist ICI 154,129 enhanced acquisition, an effect opposite that produced by LE and DPDPE. The results suggest that activation of delta-receptors is normally involved in the modulation of active avoidance learning.
C-terminal propeptide is required for fibrillin-1 secretion and blocks premature assembly through linkage to domains cbEGF41-43 (2014)

Fibrillin microfibrils are 10-12 nm diameter, extracellular matrix assemblies that provide dynamic tissues of metazoan species with many of their biomechanical properties as well as sequestering growth factors and cytokines. Assembly of fibrillin monomers into microfibrils is thought to occur at the cell surface, with initial steps including proprotein processing, multimerization driven by the C terminus, and the head-to-tail alignment of adjacent molecules. At present the mechanisms that regulate microfibril assembly are still to be elucidated. We have used structure-informed protein engineering to create a recombinant, GFP-tagged version of fibrillin-1 (GFP-Fbn) to study this process. Using HEK293T cells transiently transfected with GFP-Fbn constructs, we show that (i) the C-terminal propeptide is an essential requirement for the secretion of full-length fibrillin-1 from cells; (ii) failure to cleave off the C-terminal propeptide blocks the assembly of fibrillin-1 into microfibrils produced by dermal fibroblasts; and (iii) the requirement of the propeptide for secretion is linked to the presence of domains cbEGF41-43, because either deletion or exchange of domains in this region leads to cellular retention. Collectively, these data suggest a mechanism in which the propeptide blocks a key site at the C terminus to prevent premature microfibril assembly.
A phase 2 study of carboplatin plus docetaxel in men with metastatic hormone‐refractory prostate cancer who are refractory to docetaxel (2007)

In men with HRPC who developed progressive disease during or shortly after treatment with docetaxel, the addition of carboplatin resulted in modest additional activity. Taxane-refractory HRPC is an area of unmet need, and the current trial has provided evidence that platinum chemotherapy may be an important therapeutic option.

The new television: Looking behind the tube: In this second part of a two-part series, the outlook for emerging direct-broadcast satellite technology and entrenched cable television is examined (1984)

For pt.I see ibid., vol.21, no.9, p.48 (1984). The outlook for emerging direct-broadcast satellite technology and entrenched cable television is examined. The two technologies are considered from the viewpoints of technology, regulation, and economics, and their effect on traditional broadcasting is examined.
New horizons in dynamic rehabilitation of paralyzed laryngeal functions. (1989)

Bilateral vocal cord paralysis can result in inspiratory difficulty, while stroke can impair swallowing and be followed by severe aspiration. Ideally, these mutually exclusive functions must be rehabilitated dynamically. The principle of the artificial reflex arc (ARA) entails appropriate pick-up information, which is then sent to a modulator that in turn synchronously stimulates the impaired effector. In vocal cord paralysis (six dogs), respiratory information has been picked up via tracheal strain gauges and transthoracic impedance electrodes, producing an analog voltage proportional to respective changes during inspiration. A trigger and a stimulator circuit were used to drive an electrode placed around a nerve-muscle pedicle previously implanted into the posterior cricoarytenoid muscle. Two msec square waves with 1.8 V amplitude and 50 Hz frequency resulted in frank vocal cord abduction synchronous with inspiratory flow. Conversely, vocal fold closure can be paced from information originating from strain gauges placed on the hypopharynx (four dogs). Stretch stimulating deglutition resulted in controlled output of a constant current stimulator driving an electrode passed around both recurrent laryngeal nerves. An adjustable stimulus from 0 to 20 mA at 25 Hz produced tetanic closure of the vocal folds. This might offer promise for electronic control of the transplanted larynx.

Acquired nevus flammeus. (1995)

This is the case of a 55-year-old male with cirrhosis who required a LeVeen shunt for relief of refractory ascites. After eight months he developed recurrence of the ascites and a erythematous patch around the surgical scar. Skin biopsy revealed a proliferation of small and medium-sized vessels throughout the dermis. The acquired form of nevus flammeus is rare an is usually preceded by trauma. This is the report of a patient with an acquired nevus flammeus associated to an obstructed peritoneovenous shunt.
Estimation of the gene frequency of lactate dehydrogenase subunit deficiencies. (1984)

To detect the frequency of lactate dehydrogenase (LDH) subunit deficiency, screening for LDH subunit deficiency was performed on 3,776 blood samples from healthy individuals in Shizuoka Prefecture by means of electrophoresis. The frequency of heterozygote with LDH-A subunit deficiency was found to be 0.185%, and with LDH-B subunit deficiency, 0.159%. The frequencies of both subunit deficiencies were not significantly different. Gene frequencies of LDH subunit deficiencies were calculated by the simple counting procedure, and the results are as follows: gene frequency of LDH-A subunit deficiency was 11.9 X 10(-4), and that of LDH-B subunit deficiency, 7.9 X 10(-4). In addition, the second case in the world of a homozygous individual with LDH-A subunit deficiency was detected by this screening. This case with regard to the characteristics of LDH-A subunit deficiency are summarized herein.

Integration and expression of a rabbit liver cytochrome P-450 gene in transgenic Nicotiana tabacum. (1991)

Cytochrome P-450 is involved in the oxidative metabolism of a broad range of substrates. We have made a chimeric construct, pSN002, containing the cDNA for rabbit liver cytochrome P-450 (IIC14) under the control of the TR2' promoter for mannopine synthase in the Agrobacterium Ti plasmid. Nicotiana tabacum was transformed with Agrobacterium tumefaciens harboring a cointegrated plasmid pSN002::pGV2260. The presence of mRNA and of the translated protein from the chimeric cytochrome P-450 gene in transgenic plants was confirmed by RNA blot hybridization and by Western blot and immunohistochemical analyses, respectively. The transformants in which the foreign cytochrome P-450 protein is expressed show marked phenotypic changes, notably a tendency rapidly to senesce. We detected 2-propenylpyrrolidine, a degradative metabolite of nicotine alkaloids, in transgenic tobacco showing this pronounced phenotypic change. Such metabolism is likely to be due to the effect of senescence and not directly to the presence of the cytochrome P-450.

In this study, I put the face detection with the camera and the person detection with the laser range sensor and a high going straight-related parametric speaker together and speak a method to transmit a sound to only a specific person.
Hmgb1-IL-23-IL-17-IL-6-Stat3 Axis Promotes Tumor Growth in Murine Models of Melanoma (2013)

In order to understand how tumor cells can escape immune surveillance mechanisms and thus develop antitumor therapies, it is critically important to investigate the mechanisms by which the immune system interacts with the tumor microenvironment. In our current study, IL-17 deficiency results in reduced melanoma tumor size, diminished numbers of proliferating cells and blood vessels, and decreased percentage of CD11b(+)Gr-1(+) MDSCs in tumor tissues. IL-17 promotes IL-6 induction and Stat3 activation. Treatment of Stat3 inhibitor WP1066 in B16-F10 tumor cells inoculated wild-type mice inhibits tumor growth. Additional administration of recombinant IL-6 into B16-F10 tumor-bearing IL-17(-/-) mice results in markedly increased tumor size and p-Stat3 expression, whereas additional recombinant IL-17 administration into B16-F10 tumor-bearing wild-type mice treated with anti-IL-6 mAb does not significantly alter the tumor growth and p-Stat3 expression. In our further study, blockade of Hmgb1-RAGE pathway inhibits melanoma tumor growth and reduces production of IL-23 and IL-17. All these data suggest that Hmgb1-IL-23-IL-17-IL-6-Stat3 axis plays a pivotal role in tumor development in murine models of melanoma, and blocking any portion of this axis will attenuate melanoma tumor growth.
A Top-Down Optimization Methodology for Mutually Exclusive Applications (2014)

Proliferation of mutually exclusive applications on circuits and the higher cost of silicon make the resource sharing more and more important. The state-of-the-art synthesis tools may often be unsatisfactory. Their efficiency may depend on the hardware description style. Nevertheless, today, different applications in a circuit can be developed by different developers. This paper proposes an efficient method to improve resource sharing between mutually exclusive applications with no dependence on the coding style. It takes the advantage of the possibility of resource sharing as done in FPGA and of predefined multiple functions as in ASIC.
Neurodegenerative phagocytes mediate synaptic stripping in Neuro-HIV (2022)

Glial cell activation is a hallmark of several neurodegenerative and neuroinflammatory diseases. During HIV infection, neuroinflammation is associated with cognitive impairment, even during sustained long-term suppressive antiretroviral therapy. However, the cellular subsets contributing to neuronal damage in the CNS during HIV infection remain unclear. Using post-mortem brain samples from eight HIV patients and eight non-neurological disease controls, we identify a subset of CNS phagocytes highly enriched in LGALS3, CTSB, GPNMB and HLA-DR, a signature identified in the context of ageing and neurodegeneration. In HIV patients, the presence of this phagocyte phenotype was associated with synaptic stripping, suggesting an involvement in the pathogenesis of HIV-associated neurocognitive disorder. Taken together, our findings elucidate some of the molecular signatures adopted by CNS phagocytes in HIV-positive patients and contribute to the understanding of how HIV might pave the way to other forms of cognitive decline in ageing HIV patient populations.

The mosquito transmission of malaria: the effects of atovaquone-proguanil (Malarone™) and chloroquine (2000)

Despite its recognized importance, the prevention of patients with malaria from continuing to infect mosquitoes after treatment is not always achieved in practice. An inevitable consequence of the prolonged life-span and relative metabolic stasis of the mature gametocytes of Plasmodium falciparum is that they are not cleared by most antimalarials, and few antimalarials block infection in the mosquito vector. Previous research on the constituents of Malarone, a new 'combined antimalarial', suggested that the active components, atovaquone and proguanil, might inhibit infectivity of gametocytes to mosquitoes. We contrast here the impact of atovaquone-proguanil and chloroquine on the transmission of P. falciparum and P. berghei. While chloroquine enhanced infectivity of P. falciparum, atovaquone-proguanil caused a significant reduction. Surprisingly, sporontocidal activity against the rodent parasite persisted long after the levels of the constituent drugs would have been expected to have fallen below effective plasma concentrations on the basis of the established pharmacokinetics of atovaquone and proguanil. The P. berghei model may thus have provided a sensitive bioassay, detecting drug(s) at levels below that normally found with the usual chemical assays.
Feasibility of a watermark application for real-time-encoding video-on-demand service (2011)

A previously developed system for embedding watermarks in video content in real time has been improved by incorporating real-time transcoding, which enables embedding of watermarks specific to the recipient. The system is targeted at services that distribute video content over the Internet. When a play command is received from a customer, the system decodes the requested video content into frame images in the server. The frame images are then watermarked, encoded, and streamed to the customer in real time. Testing of the improved system showed that its use is feasible for video-on-demand service; that is, up to 20 individually watermarked videos can be concurrently streamed to customers. Visibility testing showed that degradation in the quality of the watermarked images was almost imperceptible. Robustness testing showed that the embedded watermarks were robust against encoding. Use of this system should help deter the illegal copying and distribution of video content.
Solid State Detectors in Behavioral Studies (1970)

The use of small solid state detectors for behavioral studies is described. These detectors can be inserted in holders cemented to the skull of freely moving animals thus enabling the determination of uptake of radioactive matermal in an area of the brain. By injecting P32 labelled Na3PO4, the rate of incorporation of phosphate in the brain under different behavioral conditions such as sleep anesthesia, learning, etc. can be followed. The advantages of this method are the repeated measurements on the same animal, the use of live animals for both psychological and physiological studies, the possibility of kinetic and turnover studies in the brain, blood, and in principle, other organs. Using the uptake of P32 together with studies involving other isotopes such as the stable isotope O18, an estimate of the energyrequirements of the brain can be made. The detector is a lithium drifted silicon device mounted in an electroform nickel tube of 2mm O.D. and a wall thickness of ≤ 25 microns. The detector is coated with 3 microns of parylene and secured in the nickel tube with an RTV potting compound. The major components of the preamplifier are: an FET, a transistor, three resistors and three capacitors mounted behind the detector in the probe. Performance characteristics and results will be described.
