A Novel Content-Adaptive Interpolation (2005)

We propose a content-adaptive interpolation algorithm for digital images. The proposed algorithm makes use of a non-linear spatial varying filter (SVF), which is simple but efficient in enlarging images. First, edge orientation statistics in an image are exploited, and then the information is used to determine suitable weights of neighboring pixels when interpolating the current pixel. Using the proposed approach, we can generate pixel values to replace missing ones such that sharp edges can be accurately reconstructed. Simulation results show that the proposed algorithm obtains better results in both subjective and objective quality measurements over existing methods.
Role of PET and SPECT in the assessment of ischemic cerebrovascular disease. (1993)

Functional neuroimaging techniques such as positron and single-photon emission computed tomography (PET and SPECT) have contributed to our knowledge of pathophysiological changes in ischemic stroke. Determinations of cerebral blood flow (CBF), cerebral blood volume (CBV), and cerebral metabolic rate of oxygen (CMRO2) permit the discrimination of various compensatory mechanisms in occlusive vascular disease, where changes in the CBF/CBV ratio indicate a perfusional reserve and increases in the oxygen extraction fraction (OEF), a metabolic reserve, that prevent ischemic tissue damage during graded flow decreases. Early in the course of acute ischemia, CBF and CMRO2 below a certain threshold (approximately 12 ml/100 g/min and/or 65 mumol/100 g/min, respectively) indicate irreversible tissue damage, while preservation of CMRO2 with decreased flow resulting in increased OEF ("misery perfusion") suggests still viable tissue up to 48 h after the attack, which, however, turns into necrosis in most instances during the following period. In a few instances such tissues can survive, suggesting a potential for effective therapy. Transient ischemic attacks are caused by less severe regional flow disturbances and the consequent metabolic changes are not so significant. In these cases the impact of obstructive vascular changes on hemodynamic reserve can be evaluated by functional tests applying CO2 or acetazolamide. While the regional cerebral metabolic rate of glucose (rCMRglu) in early ischemia is often not coupled to flow or CMRO2 and might even be increased (nonoxidative glycolysis with consequent tissue lactacidosis), this variable is the best indicator of permanent impairment of tissue function.

Bringing the internet to all electronic devices (1999)

In order to develop appropriate solutions for embedded device networking, we must understand the benefits offered to the end user of the device as well as the costs involved with delivering a solution. As proponents of networking technology, it is tempting to overestimate the perceived value of connectivity, while at the same time overlook the hidden costs in implementation. It is important to remember that companies adopting technology for embedded device networking are manufacturers who tend to be very conservative due to narrow margins and fierce competition. A prerequisite to wide adoption of this networking technology is a convincing case for a strong return on investment. Therefor, all optimism must temporarily be put aside for a critical cost/benefits analysis that will provide criteria for judging the suitability of proposed solutions.

Since there are so many embedded applications, it is not surprising that quite a few applications are 'no-brainers' which require little deliberation as to value or implementation method. Administration of networking hard-ware, for example, is increasingly accomplished through Internet-based device interfaces.

Internet standards and associated technologies provide a remarkable set of opportunities for enhancing the value of existing and new embedded products. These Internet technologies have been available to millions of large, 32- and 64-bit systems for some time. The key challenge we have undertaken is to establish a distributed device-networking platform that provides appropriate solutions for all embedded devices. Our goal is to make connectivity practical even for systems that do not have convenient networking already available and are severely constrained by economic pressures.
Two estrogen receptors expressed in the teleost fish, Sparus aurata: cDNA cloning, characterization and tissue distribution (2000)

Estrogen is an essential hormone for many reproductive and non-reproductive functions. The function of estrogen in the reproductive cycle of seabream (Sparus aurata), a protandrous hermaphrodite teleost fish, is complex but it is understood to be involved in sex inversion, a process that occurs in some individuals during the second reproductive season. Estrogen action is mediated by two estrogen receptor (ER) subtypes designated alpha and beta. As a step to understanding the mechanisms of estrogen action during natural and induced sex reversal in seabream, we have isolated two cDNAs encoding distinct forms of ER homologous to mammalian ERalpha and ERbeta. The seabream ERalpha clone (sbERalpha1), which was truncated in the A/B domain, corresponded to a variant differing in five amino acids from another recently cloned sbERalpha. The ERbeta clone (sbERbeta) encoded a protein 559 amino acids long and showed only 40% identity to sbERalpha. Northern blot analysis of liver and ovary mRNA indicated the presence of several transcripts of the two receptor subtypes. PCR analysis showed that the two receptors differed in their expression pattern. sbERalpha had a more restricted distribution, occurring mainly in testis, liver and heart, and sbERbeta was present in most tissues, being more abundant in ovary, testis, liver, intestine and kidney. The presence in seabream of two ERs with several ER transcripts and their pattern of distribution are consistent with the widespread effects of estrogen in different tissues.
[Effects of intracoronary autologous bone marrow mononuclear cells transplantation in patients with anterior myocardial infarction]. (2006)

Our results indicate that intracoronary transplantation of ABMMNCs could improve the left ventricular systolic function and beneficially affect myocardial perfusion up to 3 months post transplantation in patients with myocardial infarction.
In vitro chemoresistance profile and expression/function of MDR associated proteins in resistant cell lines derived from CCRF-CEM, K562, A549 and MDA MB 231 parental cells. (2002)

Although cellular experiments have elucidated a number of active principles in the study of the multidrug resistance (MDR) phenomena, most of the drug resistant tumor cells were derived from different parental cell lines. This fact limits generalization of some experimental data and conclusions, and therefore we selected and characterized cell lines resistant to various anti-cancer agents derived from four parental cell lines: CEM (human T-lymphoblastic leukemia), K562 (human myeloid leukemia), A549 (human lung adenocarcinoma) and MDAMB 231 (human breast adenocarcinoma). In total we obtained a set of 42 resistant sublines, which is an excellent tool for the future studies of different aspects of MDR. In this study we report on some basic characteristics of these sublines, namely, cross-resistance to other anti-cancer drugs investigated by in vitro MTT assay, expression of MDR associated proteins (Pgp, MRP1, LRP, GST-pi and Topo IIalpha) as well as the functional activity of Pgp and MRP.
Fast camera self-calibration for synthesizing Free Viewpoint soccer Video (2017)

Recently, non-fixed camera-based free viewpoint sports video synthesis has become very popular. Camera calibration is an indispensable step in free viewpoint video synthesis, and the calibration has to be done frame by frame for a non-fixed camera. Thus, calibration speed is of great significance in real-time application. In this paper, a fast self-calibration method for a non-fixed camera is proposed to estimate the homography matrix between a camera image and a soccer field model. As far as we know, it is the first time to propose constructing feature vectors by analyzing crossing points of field lines in both camera image and field model. Therefore, different from previous methods that evaluate all the possible homography matrices and select the best one, our proposed method only evaluates a small number of homography matrices based on the matching result of the constructed feature vectors. Experimental results show that the proposed method is much faster than other methods with only a slight loss of calibration accuracy that is negligible in final synthesized videos.
CRF/NPY interactions: A potential role in sleep dysregulation in depression and anxiety (1997)

Neuropeptide Y (NPY) has neuromodulatory actions on multiple brain functions including endocrine, behavioral, and circadian processes and has been implicated in the pathophysiology of both anxiety and depression. Behavioral studies suggest that NPY is a potent anxiolytic, whereas CRF is anxiogenic, thus it seems that a balance of these two peptides may exert important influences on behavioral state regulation. However, little is known about how the NPY/CRF balance affects general arousal, attention, and/or sleep states. The present study evaluated the effects of CRF alone, and co-administered with NPY, on spontaneous brain activity as well as on auditory processing using electrophysiological measures. Electroencephalographic (EEG) and event-related potentials (ERPs) were obtained in rats following intracerebroventricular administration of CRF (0.5 microgram) and CRF (0.5 microgram)/NPY (5.0 or 15 micrograms). Auditory processing, as assessed by ERPs, was affected most significantly in the frontal cortex where CRF produced increases in the N1 and P3 components of the ERP, and NPY/CRF co-administration produced significant decreases. These data are consistent with a role for CRF in hyperarousal, and further suggest that NPY may be capable of reversing such states. Administration of CRF also produced a significant increase in the time to sleep onset and a decrease in the amount of time spent in non-rapid eye movement (NREM) sleep as quantified by scoring the EEG paper records. Co-administration of NPY with CRF reversed the effects of CRF on sleep duration and sleep onset in a dose-dependent fashion. Spectral analysis revealed that CRF produced quantitative changes in the EEG that were similar to what has previously been reported. CRF-induced increases in fast frequency activity were found to be reversed by co-administration of NPY. Taken together these data suggest that "dysregulation" of sleep and arousal states in depression and anxiety may be consistent with an upset of the balance between hypothalamic neuropeptide systems.
Effect of the Intensity of Transcutaneous Acupoint Electrical Stimulation on the Postoperative Analgesic Requirement (1997)

Given the inherent side effects associated with both opioid and nonopioid analgesic drugs, a nonpharmacologic therapy that could decrease the need for analgesic medication would be valuable. We designed a sham-controlled study to assess the effect of the intensity of transcutaneous acupoint electrical stimulation (TAES) on postoperative patient-controlled analgesia (PCA) requirement for hydromorphone (HM), the incidence of opioid-related side effects, and the recovery profile after lower abdominal surgery. One hundred one healthy consenting women undergoing lower abdominal procedures with a standardized general anesthetic technique were randomly assigned to one of four postoperative analgesic treatment regimens: Group I (n = 26) PCA only; Group II (n = 25), PCA + sham-TAES (no electrical stimulation); Group III (n = 25), PCA + low-TAES (4-5 mA of electrical stimulation); Group IV (n = 25), PCA + high-TAES (9-12 mA of electrical stimulation). The PCA device was programmed to deliver HM, 0.2-0.4 mg intravenously boluses "on demand," with a minimum lockout interval of 10 min. The TAES skin electrodes were placed at the Hegu acupoint on the nondominant hand and on both sides of the surgical incision. The TAES frequency was set in the dense-and-disperse mode, alternating at 2 Hz and 100 Hz every 3 s, with stimulation of the hand and incision alternated every 6 s. The patients in Groups II-IV were instructed to use TAES every 2 h for 30 min while awake. After discontinuation of PCA, oral pain medications were administered on demand. The postoperative PCA-HM requirement, pain scores, opioid-related side effects, and requirements for antiemetic and antipruritic medication were recorded. High-TAES decreased the HM requirement by 65% and reduced the duration of PCA therapy, as well as the incidence of nausea, dizziness, and pruritus. Low-TAES produced a 34% decrease in the HM requirement compared with only 23% in the "sham" TAES group. We conclude that high-TAES produced a significant decrease in the PCA opioid requirement and opioid-related side effects after low intraabdominal surgery.
Path selection and emergency item allocation model based on fuzzy multiple objective programming (2010)

Considering the uncertainty of emergency item demand in emergency logistics, the transportation paths from item supply spots to disaster spots and emergency item allocation to the selected paths are simultaneously determined by introducing a fuzzy multiple objective mixed integer programming model. The model aims to achieve the minimization of both transportation cost and transportation time. Furthermore, the solution procedure for this model is illustrated. At last, a numerical example is given to verify the availability of above model and perform the sensitivity analysis. It is shown from the sensitivity analysis that the transportation cost and transportation time are increasing in the degree of uncertainty in disaster spots' item demand.
Optical interconnection schemes using micro-optic connectors for passive packaging in optical PCBs (2005)

Two types of fiber-embedded micro-optic connectors were proposed for passive packaging in the optical PCB. In the first type, 1 /spl times/ 12 silica optical fibers having 100/110 /spl mu/m core/cladding diameters were bent by 90-degree and mounted in a tetragonal body with a /spl sim/3 /spl times/ 3 /spl times/ 5 mm/sup 2/ size. The measured bending losses of the fibers were -0.61 dB, -0.46 dB, and -0.21dB when the radii of curvature are 1.0 mm, 1.5 mm, and 2.0 mm, respectively. The side and bottom surfaces of the tetragonal block were mechanically polished to reveal smooth apertures at the ends of the fibers. In the second type, a plastic fiber bundle was bent by 90/spl deg/ and mounted also in a tetragonal body with a millimeter scale size. The core sizes of the individual fibers in the bundle were about 10 /spl mu/m and 20 /spl mu/m, and the diameters of the bundle were about 0.55 mm and 1 mm, respectively. The bending loss of the 90/spl deg/-bent fiber bundle was approximately -0.8 dB for 0.55 mm diameter and -1.4 dB for 1 mm diameter with a curved radius of /spl sim/1.5 mm. This fiber bundle block can provide a very large tolerance above several hundred micrometers in the alignment in vertical and lateral directions between the connector and the optical layers in OPCBs. We have successfully demonstrated 2.5 Gb/s data link assembling both types of connectors in the fiber-embedded PCBs.
Training Japanese listeners to identify English /r/ and /l/. II: The role of phonetic environment and talker variability in learning new perceptual categories (1993)

Two experiments were carried out to extend Logan et al.'s recent study [J. S. Logan, S. E. Lively, and D. B. Pisoni, J. Acoust. Soc. Am. 89, 874-886 (1991)] on training Japanese listeners to identify English /r/ and /l/. Subjects in experiment 1 were trained in an identification task with multiple talkers who produced English words containing the /r/-/l/ contrast in initial singleton, initial consonant clusters, and intervocalic positions. Moderate, but significant, increases in accuracy and decreases in response latency were observed between pretest and posttest and during training sessions. Subjects also generalized to new words produced by a familiar talker and novel words produced by an unfamiliar talker. In experiment 2, a new group of subjects was trained with tokens from a single talker who produced words containing the /r/-/l/ contrast in five phonetic environments. Although subjects improved during training and showed increases in pretest-posttest performance, they failed to generalize to tokens produced by a new talker. The results of the present experiments suggest that variability plays an important role in perceptual learning and robust category formation. During training, listeners develop talker-specific, context-dependent representations for new phonetic categories by selectively shifting attention toward the contrastive dimensions of the non-native phonetic categories. Phonotactic constraints in the native language, similarity of the new contrast to distinctions in the native language, and the distinctiveness of contrastive cues all appear to mediate category acquisition.

A fault modeling technique to test memory BIST algorithms (2003)

The amount of memory being embedded on chip is growing rapidly. This strongly implies that memory built-in-self-test (BIST) logic assumes utmost importance amongst all on chip self test logic. Therefore the BIST logic should be comprehensively validated before fabrication. The key to this achievement lies in a robust memory fault model. In this paper we propose a novel fault modeling technique. This technique can scale to emulate any kind of memory architecture currently in use. The memory architecture and the location of any fault that can occur in the cell array are represented in terms of equations. The technique applies these equations and calculates an address where the fault can be modeled.
Synthesis, Characterization, and Solution Properties of Skeletally Stabilized Triphosphazanes (1999)

The new skeletally stabilized dichlorotriphosphazanes C6H4N2(PhPCl)2PPh (5) and C6H4N2(MePCl)2PMe (6) have been prepared from reactions between PhPCl2 or MePCl2 and 1,2-(NH2)2C6H4 or 1,2-(Me3SiNH)2C6H4, respectively. Reaction of PhPCl2 with the phosphadiazole C2H4(Me3SiN)2PPh yields triphosphazane C2H4N2(PhPCl)2PPh (8). Compounds 5, 6, and 8 form as mixtures of three diastereomers; characterization is based on spectral data and derivatization of 5 and 8 to the amino and thio(amino) triphosphazanes C6H4N2[PhP(NHiPr)]2PPh (7) and C2H4N2[PhP(S)NEt2]2PPh (10). The 31P NMR spectra of 5 and 6 in solution have been measured as a function of temperature and solvent donor and dielectric strength. The solution properties of the dichlorotriphosphazanes and the implications of these on subsequent reaction chemistry are discussed.

Optimization Of Solar Tracking Systems (2018)

In this paper, an intelligent approach is proposed to optimize the orientation of continuous solar tracking systems on cloudy days. Considering the weather case, the direct sunlight is more important than the diffuse radiation in case of clear sky. Thus, the panel is always pointed towards the sun. In case of an overcast sky, the solar beam is close to zero, and the panel is placed horizontally to receive the maximum of diffuse radiation. Under partly covered conditions, the panel must be pointed towards the source that emits the maximum of solar energy and it may be anywhere in the sky dome. Thus, the idea of our approach is to analyze the images, captured by ground-based sky camera system, in order to detect the zone in the sky dome which is considered as the optimal source of energy under cloudy conditions. The proposed approach is implemented using experimental setup developed at PROMES-CNRS laboratory in Perpignan city (France). Under overcast conditions, the results were very satisfactory, and the intelligent approach has provided efficiency gains of up to 9% relative to conventional continuous sun tracking systems.
Control of posterior pituitary vasopressin content: implications for the regulation of the vasopressin gene. (1994)

Axon terminals in the posterior pituitary store large quantities of the hormone vasopressin (AVP), buffering the synthesizing neurons in the hypothalamus against acute changes in physiological demand for hormone release. The dynamics of pituitary AVP content reflect the competing processes of release and synthesis. This report demonstrates substantial increases in pituitary AVP content in the maturing rat. Between 7-10 weeks of age, the total pituitary AVP content in the rat increases from 957 +/- 72 to 1667 +/- 160 ng. Cross-sectional data indicate a parallel relationship between body weight and pituitary AVP content. Nevertheless, weight maintenance does not affect age-related increases in AVP content. Decreasing demand for hormone release and synthesis by inducing hyponatremia blocks subsequent pituitary accumulation. After withdrawing the hyponatremic experimental conditions, animals resume accumulation of pituitary AVP, but do not catch up to age-matched controls. This indicates that increases in pituitary AVP content do not result from a feedback signal from the neural lobe, but rather, pituitary AVP levels passively reflect changes in hormone release and compensatory synthesis.
Audience Validation from Demographic Mix and Insufficient Individual Data (2016)

An advertiser usually provides a specific demographic target to a content publisher. But due to the limited profile information on each viewer, the publisher suffers from low accuracy in targeting. Once an advertisement is shown to viewers, a third party (like Nielsen, Comscore) validates how close the publisher was to the target audience. Publisher also receives the demographic mix of each show from the third party. Low accuracy in targeting is expensive as the publisher gets paid only for the impressions which were on target. In this work, we propose a new approach to incorporate user level latent features developed from the show-wise demographic mix provided by the third party, along with session level features of viewers to improve the demographic predictions. In congruence with current industry practice, we train our model on a small labeled demographic segment and establish the effectiveness of our approach over existing approaches through experiments.
Pressure- and temperature-induced unfolding and aggregation of recombinant human interferon-gamma: a Fourier transform infrared spectroscopy study (2003)

The effect of hydrostatic pressure on the secondary structure of recombinant human interferon-gamma (rhIFN-gamma) and its biologically inactive truncated form rhIFN-Delta C15 has been studied using Fourier-transform IR (FTIR) spectroscopy. In situ observation of the pressure-induced changes using the diamond anvil cell shows that the alpha-helical structure is mainly transformed into disordered structure at high pressure. Increasing pressure also induces the formation of a gel. Addition of 0.5 M MgCl(2) significantly reduces the pressure stability. Releasing the pressure below 300 MPa results in the formation of intermolecular antiparallel beta-sheets, which is seldom observed. This suggests that the intermolecular beta-sheet of rhIFN-gamma is stabilized by electrostatic interactions that are disrupted at high pressure. For comparison we also studied the effect of temperature. Temperature-induced changes reflect extensive transformation of alpha-helical structure into intermolecular antiparallel beta-sheet, as is usually observed for most proteins.
