Data Fusion Algorithms for Multiple Inertial Measurement Units (2011)

A single low cost inertial measurement unit (IMU) is often used in conjunction with GPS to increase the accuracy and improve the availability of the navigation solution for a pedestrian navigation system. This paper develops several fusion algorithms for using multiple IMUs to enhance performance. In particular, this research seeks to understand the benefits and detriments of each fusion method in the context of pedestrian navigation. Three fusion methods are proposed. First, all raw IMU measurements are mapped onto a common frame (i.e., a virtual frame) and processed in a typical combined GPS-IMU Kalman filter. Second, a large stacked filter is constructed of several IMUs. This filter construction allows for relative information between the IMUs to be used as updates. Third, a federated filter is used to process each IMU as a local filter. The output of each local filter is shared with a master filter, which in turn, shares information back with the local filters. The construction of each filter is discussed and improvements are made to the virtual IMU (VIMU) architecture, which is the most commonly used architecture in the literature. Since accuracy and availability are the most important characteristics of a pedestrian navigation system, the analysis of each filter’s performance focuses on these two parameters. Data was collected in two environments, one where GPS signals are moderately attenuated and another where signals are severely attenuated. Accuracy is shown as a function of architecture and the number of IMUs used.
Knowledge-based approaches for scheduling problems: a survey (1991)

Recent developments in artificial intelligence (AI) have led to the use of knowledge-based techniques for solving scheduling problems. The authors survey several existing intelligent planning and scheduling systems with the aim of providing a guide to the main AI techniques used. In view of the prevailing difference is usage of the terms planning and scheduling between AI and operations research (OR), a taxonomy of planning and scheduling problems is presented. The modeling of real world problems from closed deterministic worlds to complex real worlds is illustrated with a project scheduling example. Some of the more successful planning and scheduling systems are surveyed, and their features are highlighted. The AI approaches are consolidated into knowledge representation and problem solving in the project management context.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Limbic-dependent recognition memory in monkeys develops early in infancy (1993)

Infantile amnesia, the absence of memories from infancy and early childhood, has been attributed to an immaturity of the limbic system in infancy. Contrary to this view, we now report that limbic-dependent recognition memory is present as early as one month of age in monkeys. Memory measured by the paired-comparison preferential looking task, normally present in infant monkeys within the first month of life, is absent after damage to the amygdaloid complex and hippocampal formation, suggesting that limbic structures make a critical contribution to visual recognition memory even at this early age. The findings reopen the question of the locus of the neural immaturity that underlies infantile amnesia.
Tears Falling on Goosebumps: Co-occurrence of Emotional Lacrimation and Emotional Piloerection Indicates a Psychophysiological Climax in Emotional Arousal (2017)

This psychophysiological study is the first to examine the relationship between emotional tears and emotional piloerection (i.e., goosebumps). Although both phenomena have been related to peak states of being moved, details about their temporal occurrence and the associated levels of physiological arousal have remained unknown. In our study, we used emotionally powerful film scenes that were self-selected by participants. Our findings show that even within peak moments of emotional arousal, a gradation of intensity is possible. The overlap of tears and goosebumps signifies a maximal climax within peak moments. On the side of the stimulus, we found that displays of prosocial behavior play a crucial role in the elicitation of tears and goosebumps. Finally, based on the results of a formal film analysis of the tears-eliciting clips provided by our participants, as compared to randomly extracted, equally long control clips from the same films, we show how the technical and artistic making of the clips was optimized for the display of social interaction and emotional expressions.

Beneficial effects of Neotyphodium lolii on the growth and the water status in perennial ryegrass cultivated under nitrogen deficiency or drought stress (1997)

— Three perennial ryegrass clones infected and uninfected with Neotyphodium lolii (formerly Acremonium lolii) were studied to determine the impact of this endophytic fungus on plant growth and physiology under stress con- ditions. Plants were grown under controlled environmental conditions for 10 weeks and were subjected to: i) no stress (12 mM of N; no limiting water supply); ii) N deficiency; or iii) drought stress. In the absence of stress, infected and non-infected plants of all clones showed similar growth rates. Under N deficiency (2.33 mM), infected plants had 27% more tillers and 15% less dead leaves than uninfected plants, and they maintained their photosynthetic level. During drought stress (0.7 MPa), the osmotic potential of the infected plants was 13% lower than that of uninfected plants and their tiller number was 10% greater than that of non-infected plants at the end of the drought stress period. Thus, in the three clones studied, the infection results in increased tolerance of host plants to abiotic stress especially as a result of better tillering. ryegrass = Lolium perenne / endophyte / drought stress / N deficiency / Neotyphodium lolii Rsum — Effets positifs de Neotyphodium lolii sur la croissance et l'tat hydrique de plants de ray-grass anglais soumis une carence en azote ou un stress hydrique. Ce travail a t effectu sur trois clones de ray-grass anglais infects ou non par Neotyphodium lolii (antrieurement Acremonium lolii), afin de dterminer l'impact de ce champignon endophyte sur la croissance et la physiologie des plantes soumises des conditions stressantes. Les plantes sont cultives pendant 10 semaines sous environnement control dans diffrentes conditions : i) aucun stress (12 mM de N ; apport en eau non limitant) ; ii) carence en azote ; ou iii) stress hydrique. En l'absence de stress, les plantes saines et endophytes, des trois gnotypes tudis, prsentent une croissance et un dveloppement identiques. En conditions de carence en azote (2,33 mM), les plantes endophytes prsentent un tallage plus important de 25 % et un nombre de feuilles mortes plus faible de 15 % par rapport aux plantes non endophytes. De plus, les plantes infectes maintien- nent leur activit photosynthtique. Pendant le stress hydrique (0,7 MPa), le potentiel osmotique des plantes endophytes est infrieur de 13 % par rapport celui mesur chez les plantes non endophytes et elles prsentent galement un tallage suprieur de 10 % en fin de stress. Dans le matriel tudi, l'infection permet une meilleure croissance des plantes cultives en conditions de carence en azote ou de stress hydrique en particulier grce un meilleur tallage.
Controlling Wettability of Boron Nitride Nanotube Films and Improved Cell Proliferation (2012)

Desired wettability has been achieved on highly hydrophobic boron nitride nanotube (BNNT) films using nitrogen/hydrogen (N2/H2) gas plasma treatments under controlled input energies and modes. Both hydrophilicity (contact angle (CA) ∼60°) and superhydrophilicity (CA < 5°) are demonstrated on BNNT films with little change of the surface morphology or the structure of individual BNNTs. The combination of continuous wave and pulse mode (CW+P) plasma shows more effective wettability modification and introduces more amine functional groups than the continuous wave (CW) plasma alone at a given input energy. (Super)hydrophilic/hydrophobic patterns have been created on BNNT films using masked plasma methods. The cell response to BNNT films is investigated for the first time. The proliferation of human primary mammary fibroblasts and a transformed mammary cell line (TXP RFP3) shows that the untreated hydrophobic BNNT films can support the growth of both cell lines, but the plasma treatments greatly enhance (up to six times) the number of cells attached to the surface of BNNT films.
Data transport applications using GFP (2002)

An emerging generic framing procedure (GFP) standard defines a new data encapsulation protocol designed to accept and transport multiple protocols over metropolitan, storage, and wide area networks. Why is another data encapsulation method needed for transporting data traffic over WANs? How does GFP encapsulate data for transport? This article provides an introduction to data transport applications, reviews existing data transport options (e.g., ATM and HDLC), introduces GFP as a new data transport technology, and compares GFP transport to existing popular alternatives.
Flexible dual TCP/UDP streaming for H.264 HD video over WLANs (2013)

High Definition video streaming over WLANs faces many challenges because video data requires not only data integrity but also frames have strict playout deadline. Traditional streaming methods that rely solely on either UDP or TCP have difficulties meeting both requirements because UDP incurs packet loss while TCP incurs delay. This paper proposed a new streaming method called Flexible Dual-TCP/UDP Streaming Protocol (FDSP) that utilizes the benefit of both UDP and TCP. The FDSP takes advantage of the hierarchical structure of the H.264/AVC syntax and uses TCP to transmit important syntax elements of H.264/AVC video and UDP to transmit non-important elements. The proposed FDSP is implemented and validated under different wireless network conditions. Both visual quality and delay results are compared against pure-UDP and pure-TCP streaming methods. Our results show that FDSP effectively achieves a balance between delay and visual quality, thus it has advantage over traditional pure-UDP and pure-TCP methods.
New image enhancement algorithm for night vision (2003)

In order to improve the clearness of images captured at night, a new enhancement algorithm is proposed in this paper. Its characters are: (1) enhancing the dark image with contrast enhancement and histogram equalization in series, so both the local and global information can be used; (2) a contrast transforming function which is suited to deal with dark image is proposed; (3) it can be realized in real time. The new method shows good performance in dealing with night vision images.
Through a Glass Darkly (2014)

A common lament is that long-term kidney transplant outcomes remain the same despite improvements in early graft survival. To be fair, progress has been made-in both our understanding of chronic injury and modestly, graft survival. However, we are still a long way from actually solving this important and difficult problem. In this review, we outline recent data supporting the existence of several causes of renal allograft loss, the incidences of which peak at different time points after transplantation. On the basis of this broadened concept of chronic renal allograft injury, we examine the challenges of clinical trial design in long-term studies, including the use of surrogate end points and biomarkers. Finally, we suggest a path forward that, ultimately, may improve long-term renal allograft survival.

Controlled dosing of nitrate for prevention of HS in a sewer network and the effects on the subsequent treatment processes (1995)

A process for the elimination of septicity based on controlled addition of nitrate to sewer networks is developed. The process is registered as the Nutriox TM process. The work described in this paper gives the results of a full scale trial in the UK. The trial was set up and managed by Norsk Hydro and independently monitored and evaluated by the Water Research Centre Environmental Management (WRc). The results showed that dosing of nitrate was very effective for suppression of hydrogen sulphide in a rising main. During nitrate dosing the average level of hydrogen sulphide at the works inlet was 0.24 mg/l, with a daily variation within the range of 0-0.4 mg/l. Without nitrate addition the average background level of hydrogen sulphide was 4.2 mg/l, with a daily variation of 1-10 mg/l. The dosing was accomplished without significant breakthrough of nitrate to the treatment works. Dosing of nitrate resulted in an increased removal of soluble BOD across the rising main, but no significant change in total BOD or COD was registered at the treatment plant during the nitrate dosing. The nitrification process in the biological filters at the treatment plant was improved during the dosing period.
Highly Convergent, Stereospecific Synthesis of 11-<i>cis</i>-Retinoids by Metal-Catalyzed Cross-Coupling Reactions of (<i>Z</i>)-1-Alkenylmetals (2007)

A stereospecific synthesis of 11-cis-retinoids has as its key step the hitherto unexplored palladium-catalyzed cross-coupling of trans-trienyl electrophiles and (1Z,3E)-penta-1,3-dienyl boronates (a Suzuki-Miyaura reaction) or stannanes (a Stille reaction). This highly convergent approach constitutes the first application of cis-organometallic moieties to the synthesis of 11-cis-retinoids and represents a general, straightforward route to the visual chromophore.
Human-centered image navigation on mobile devices (2008)

How to navigate large images on mobile device is an open problem due to small display screen. Currently region of interest (ROI) image compressing is a popular approach. However, since the semantics of image is diversified by different users, it is hard to extract general ROI. In this paper, we propose a human-centered image navigation method for mobile users with simple human interaction. Different from previous work, we first extract Local Saliency Map (LSM) of an image according to personalized requirement, which can reduce the semantic ambiguity of the image for different users. Based on LSM, we can detect the ROIs of the image, which fully satisfies the different interests of the different users. Experiments and user studies show an encouraging performance of the proposed method.
Property Testing (1992)

Testing is an essential part of any engineering activity. Inspection and testing must take place at many stages in the complex process of producing engineering materials, be they metals, polymers, ceramics or composites, and during the forming of these materials into components and assembling the components to create an engineering product to satisfy some specific requirement. The requirement for testing does not automatically cease when the product has been manufactured. It is frequently necessary to check and test the article during its service life in order to monitor changes, such as the possible development of fatigue or corrosion damage.
Wegener autoantigen and myeloblastin are encoded by a single mRNA. (1991)

Myeloblastin is a serine protease that has been identified in the human leukemia cell line HL-60. Down-regulation of this protease can inhibit proliferation and induce differentiation of promyelocyte-like human leukemic cells. Proteinase 3, a serine protease of human neutrophils, has been identified as the Wegener autoantigen. A high level of homology between myeloblastin and proteinase 3 has suggested that they may be a single serine protease. We have recently completed the 5'-terminal nucleotide sequence of proteinase 3 and shown that its mRNA was also expressed in HL-60 cells and in cells from patients with acute myeloid leukemia. Here we demonstrate that myeloblastin and proteinase 3 are encoded by a single mRNA.
M-phase MELK activity is regulated by MPF and MAPK (2006)

The protein kinase MELK is implicated in the control of cell proliferation, cell cycle and mRNA splicing. We previously showed that MELK activity is correlated with its phosphorylation level, is cell cycle dependent, and maximal during mitosis. Here we report on the identification of T414, T449, T451, T481 and S498 as residues phosphorylated in Xenopus MELK (xMELK) in M-phase egg extract. Phosphorylations of T449, T451, T481 are specifically detected during mitosis. Results obtained in vivo showed that MPF and MAPK pathways are involved in xMELK phosphorylation. In vitro, MPF and MAPK directly phosphorylate xMELK and MPF phosphorylates xMELK on T481. In addition, phosphorylation by MPF and MAPK enhances MELK activity in vitro. Taken together our results indicate that MELK phosphorylation by MPF and MAPK enhance its activity during M-phase.
CMOS true-time delay IC for wideband phased-array antenna (2018)

This paper presents a true-time delay (TTD) using a commercial 0.13-μm CMOS process for wideband phased-array antennas without the beam squint. The proposed TTD consists of four wideband distributed gain amplifiers (WDGAs), a 7-bit TTD circuit, and a 6-bit digital step attenuator (DSA) circuit. The T-type attenuator with a low-pass filter and the WDGAs are implemented for a low insertion loss error between the reference and time-delay states, and has a flat gain performance. The overall gain and return losses are >7 dB and >10 dB, respectively, at 2 GHz–18 GHz. The maximum time delay of 198 ps with a 1.56-ps step and the maximum attenuation of 31.5 dB with a 0.5-dB step are achieved at 2 GHz–18 GHz. The RMS time-delay and amplitude errors are <3 ps and <1 dB, respectively, at 2 GHz–18 GHz. An output P1 dB of <−0.5 dBm is achieved at 2 GHz–18 GHz. The chip size is 3.3 × 1.6 mm2, including pads, and the DC power consumption is 370 mW for a 3.3-V supply voltage.
The relationship between positioning, the breastfeeding dynamic, the latching process and pain in breastfeeding mothers with sore nipples. (2003)

In recognition of the irrefutable disadvantages of not breastfeeding to the mother, baby, society and the environment, increasing the duration of breastfeeding has become a focus of national and international health objectives. However, many mothers experience such painful sore nipples that they stop breastfeeding before they intended. The purpose of this study is to examine the relationship between various aspects of optimal breastfeeding (e.g. the positioning of the baby at the mother's breast, the positioning of the baby's head and mouth, the breastfeeding dynamic and the latching process) using a guided assessment and documentation tool and the breastfeeding mother's level of reported pain on a five-point verbal descriptor scale. Ninety-five healthy postpartum breastfeeding mothers who sequentially reported sore nipples within ten days of giving birth to healthy, term babies in a hospital in Latvia participated in the study. Each mother's midwife observed, assessed and documented a breastfeed using a guidance assessment form, the Lactation Assessment Tool (LAT). Each mother scored her own pain during breastfeeding. Four attribute categories were scored and examined as related to the pain levels of the mother: the baby's face position (chin and nose and head position, cheekline, lip flange and angle of mouth opening); the baby's body position (height at the breast, body rotation and body in relation to mother's body); the breastfeeding dynamic (change in breastfeeding pattern (suck vs swallow) and movement of mother's breast) and the latching process of the baby (root, gape, seal and suck). No significant difference was found between the mother's level of reported pain and the assessed head position, body position or breastfeeding dynamic attributes of the baby. However, more optimal latching process behaviour of the baby (rooting, gaping, sealing, and sucking behaviour) are slightly related to lower levels of reported pain (r(88) = -0.09, p > 0.05). This should serve to remind clinicians that no one aspect of positioning may be more critical than another. Assessment of breastfeeding should be comprehensive and should begin before the infant is at the breast. Early stages of the infant's breast seeking behaviours should be observed as well as the actual feeding.
Accurate Reconstruction of Cell and Particle Tracks from 3D Live Imaging Data (2016)

Spatial structures often constrain the 3D movement of cells or particles in vivo, yet this information is obscured when microscopy data are analyzed using standard approaches. Here, we present methods, called unwrapping and Riemannian manifold learning, for mapping particle-tracking data along unseen and irregularly curved surfaces onto appropriate 2D representations. This is conceptually similar to the problem of reconstructing accurate geography from conventional Mercator maps, but our methods do not require prior knowledge of the environments' physical structure. Unwrapping and Riemannian manifold learning accurately recover the underlying 2D geometry from 3D imaging data without the need for fiducial marks. They outperform standard x-y projections, and unlike standard dimensionality reduction techniques, they also successfully detect both bias and persistence in cell migration modes. We demonstrate these features on simulated data and zebrafish and Drosophila in vivo immune cell trajectory datasets. Software packages that implement unwrapping and Riemannian manifold learning are provided.
