Using Boosted Features for the Detection of People in 2D Range Data (2007)

This paper addresses the problem of detecting people in two dimensional range scans. Previous approaches have mostly used pre-defined features for the detection and tracking of people. We propose an approach that utilizes a supervised learning technique to create a classifier that facilitates the detection of people. In particular, our approach applies AdaBoost to train a strong classifier from simple features of groups of neighboring beams corresponding to legs in range data. Experimental results carried out with laser range data illustrate the robustness of our approach even in cluttered office environments
Spatial and Seasonal Distribution of Pine Root Collar Weevil Eggs in Young Red Pine Plantations (2017)

The pine root collar weevil (Hylobius radicis Buchanan) is a continuous threat to young pine plantations in the northeastern United States and the adjacent Canadian Provinces The female weevil oviposits during the daytime (Wilson, 1968a) near the root collars of red pine (Pinus resinosa Aiton), Scotch pine (P. sylvestris L.), and jack pine (P. hanksiana Lambert), and occasionally other pines. During recent studies on the weevil (Wilson 1968a, 1968b) in Michigan, egg data were taken for use in population and sampling research. Presented here are distribution patterns of eggs within and between trees and throughout the oviposition period, and some implications for assessing populations.
On Applying Imprecise Computation to Real-Time AI Systems (1995)

Imprecise computation is known as a technique for real-time systems where precise outputs are traded off for timely responses to system events. This paper discusses how the technique can be applied to a class of real-time Al systems designed for solving combinatorial problems and proposes an evaluation method for assessing if imprecise computation can satisfy both the timing and functional requirements of these systems.
Baroreflex sensitivity determined by spectral method and heart rate variability, and two-years mortality in patients after myocardial infarction (2000)

Sympathetic overactivity and low parasympathetic activity is an autonomic dysfunction (AD) which enhances cardiac mortality. In the present study, the impact of AD on the mortality in patients after myocardial infarction was evaluated. We examined 162 patients 7-21 days after myocardial infarction, 20 patients of whom died in the course of two years. Baroreflex sensitivity (BRS) was estimated by spectral analysis of spontaneous fluctuations of systolic blood pressure and cardiac intervals (Finapres, 5 min recording, controlled breathing 20/min). The heart rate variability was determined as SDNN index (mean of standard deviations of RR intervals for all 5-min segments of 24-hour ECG recordings). BRS < 3 ms/mm Hg and/or SDNN index < 30 ms were taken as markers of AD. The risk stratification was performed according to the number of the following standard risk factors of increased risk of cardiac mortality (SRF): ejection fraction < 40%, positive late potentials and the presence of ventricular extrasystoles > 10/h. No difference in mortality between patients with AD (4%) and without AD (4.5%) was found in 92 patients without SRF, the mortality in 6 patients with three SRF was 66.6%. Five of these patients had AD. Out of 64 patients with one or two SRF, 32 had AD. The mortality of patients without AD was 6.25% and 31.2% of those with AD (p<0.025). It is concluded that AD enhanced two-years mortality five fold in our patients with moderate risks.
Onboard guarded software upgrading: motivation and framework (2002)

The goal of the guarded software upgrading (GSU) framework is to minimize mission performance loss due to onboard software upgrading activities and that due to system failure caused by residual faults in an upgraded version. We exploit inherent system resource redundancies as the means of fault tolerance to meet the development cost and onboard resource constraints. Furthermore, we devise a message-driven confidence-driven protocol to facilitate effective and efficient error containment and recovery.
Urinary <i>p</i>-cresol is elevated in small children with severe autism spectrum disorder (2011)

Several studies have described in autistic patients an overgrowth of unusual gut bacterial strains, able to push the fermentation of tyrosine up to the formation of p-cresol. We compared levels of urinary p-cresol, measured by high-performance liquid chromatography-ultraviolet, in 59 matched case-control pairs. Urinary p-cresol was significantly elevated in autistic children smaller than 8 years of age (p < 0.01), typically females (p < 0.05), and more severely affected regardless of sex (p < 0.05). Urinary cotinine measurements excluded smoking-related hydrocarbon contaminations as contributors to these differences. Hence, elevated urinary p-cresol may serve as a biomarker of autism liability in small children, especially females and more severely affected males.
Immobilization increases bone prostaglandin E: Effect of acetylsalicylic acid on disuse osteoporosis studied in dogs (1991)

The effect of acetylsalicylic acid (aspirin) on bone mass and bone prostaglandin E (PGE) in immobilization osteoporosis was studied in 12 growing dogs using a unilateral hind limb cast-fixation model. Osteoporosis was induced by fiberglass-cast immobilization of the right hind limb for 4 weeks, with the left hind limb as a control. Six dogs received buffered aspirin at 25 mg/kg body weight per os every 8 hours; 6 dogs received no treatment. All the dogs were killed after 4 weeks, and bone samples were collected. Bone mineral content of the distal tibial metaphysis was measured by single-photon absorptiometry. In vitro release of PGE from the calcaneus, tibial cortical bone, tibial cancellous bone, and ilium were measured using a specific radioimmunoassay for PGE. Compared with the controls, the casted limb of untreated dogs had half the bone mass and a twofold increase in bone PGE. Aspirin treatment was associated with a 65 percent reduction in bone PGE and a 13 percent bone mass sparing effect. These results provide indirect evidence that PGE plays a role in immobilization osteoporosis.
Amplification d'impulsions femtosecondes à 1550 nm en régime de dispersion anomale (2009)

Nous explorons dans ce travail les possibilités, les enjeux et les défis associés à l'amplification d'impulsions brèves provenant d'une source laser dans des fibres optiques en régime de dispersion anomale à la longueur d'onde de 1550 nm. Notre analyse des résultats obtenus en laboratoire lors du développement de la chaîne d'amplification est supportée par le biais de simulations numériques permettant une meilleure identification des mécanismes intervenant dans la dynamique. Ces principaux effets sont la dispersion d'ordre deux, la dispersion d'ordre trois, l'automodulation de phase et la diffusion Raman. Nous avons pu déterminer que l'action conjointe de ces mécanismes pouvait entraîner des régimes de filamentation temporelle limitant l'amplification. La chaîne d'amplification que nous avons développée est basée sur le principe d'amplification d'impulsions glissées en fréquence dans des fibres optiques (FCPA). Une attention particulière a été portée à l'optimisation et à la complémentarité des sous-éléments formant cette chaîne. Nous avons été en mesure d'obtenir après amplification un gain de 100 en puissance crête. Les impulsions ont des durées inférieures à 320 fs et des énergies de l'ordre de 300 nJ. La cadence d'émission de ces impulsions est ajustable entre 1 et 2 MHz. Ce sont, à notre connaissance, les impulsions les plus courtes à avoir été produites à ce niveau de puissance avec un système laser à fibres dopées à Terbium.

Th17 and Non-Classic Th1 Cells in Chronic Inflammatory Disorders: Two Sides of the Same Coin (2014)

Th17 lymphocytes, beyond their protective role in the clearance of extracellular pathogens, also play a role in the pathogenesis of several autoimmune and inflammatory diseases, such as multiple sclerosis, rheumatoid arthritis, inflammatory bowel diseases, psoriasis and contact dermatitis. Nevertheless, they are very rare at inflammatory sites in comparison with other T cell subsets. Recently, this rarity has been explained by the finding that Th17 cells rapidly shift into the Th1 phenotype in the presence of IL-12 and/or TNF-α as well as by the fact that they possess self-regulatory mechanisms limiting their own expansion. Th17 lymphocytes that have shifted towards a Th1 phenotype seem to be particularly aggressive and more pathogenic than the Th17 unshifted cells. As a consequence, the Th17-derived Th1 cells, named non-classic Th1 cells, can become a possible target for the therapy of some inflammatory disorders. In particular, convincing evidence has recently been accumulated indicating that this subset can play a role in Crohn's disease and juvenile idiopathic arthritis. More importantly, it has been shown that TNF-α inhibitors, which are used for the treatment of such diseases, appear to be able to inhibit the transition of Th17 lymphocytes to the non-classic Th1 phenotype, and thus they possibly help to dampen inflammation and arrest disease progression. Based on this context, the definition of the soluble factors involved in the shifting from Th17 towards non-classic Th1 subset as well as the comprehension of their respective pathogenic role in human inflammatory disorders would be of great help for developing novel therapeutic strategies.

Adversarial Network Embedding (2017)

Learning low-dimensional representations of networks has proved effective in a variety of tasks such as node classification, link prediction and network visualization. Existing methods can effectively encode different structural properties into the representations, such as neighborhood connectivity patterns, global structural role similarities and other high-order proximities. However, except for objectives to capture network structural properties, most of them suffer from lack of additional constraints for enhancing the robustness of representations. In this paper, we aim to exploit the strengths of generative adversarial networks in capturing latent features, and investigate its contribution in learning stable and robust graph representations. Specifically, we propose an Adversarial Network Embedding (ANE) framework, which leverages the adversarial learning principle to regularize the representation learning. It consists of two components, i.e., a structure preserving component and an adversarial learning component. The former component aims to capture network structural properties, while the latter contributes to learning robust representations by matching the posterior distribution of the latent representations to given priors. As shown by the empirical results, our method is competitive with or superior to state-of-the-art approaches on benchmark network embedding tasks.

Influenza virus polymerase basic protein 1 interacts with influenza virus polymerase basic protein 2 at multiple sites (1996)

Three polymerase proteins of influenza type A virus interact with each other to form the active polymerase complex. Polymerase basic protein 1 (PB1) can interact with PB2 in the presence or absence of polymerase acidic protein. In this study, we investigated the domains of PB1 involved in complex formation with PB2 in vivo, using coexpression and coimmunoprecipitation of the PB1-PB2 complex with monospecific antibodies. Results show that PB1 possesses at least two regions which can interact independently and form stable complexes with PB2. Both of these regions are located at the NH2 terminus of PB1; the COOH-terminal half of PB1 is not involved in interacting with PB2. Deletion analysis further demonstrated that the interacting regions of PB1 encompass amino acids (aa) 48 to 145 and aa 251 to 321. Linker insertions throughout the PB1 sequences did not affect complex formation with PB2. Deletion and linker-insertion mutants of PB1 were tested for polymerase activity in vivo. For this analysis, we developed a simplified assay for viral polymerase activity that uses a reporter chloramphenicol acetyltransferase gene containing the 5' and 3' ends of influenza viral promoter and nontranslating regions (minus sense) of the NS gene joined to a hepatitis delta virus ribozyme at its 3' end. This assay demonstrated that all deletion mutants of PB1 exhibited either background or greatly reduced polymerase activity irrespective of the ability to interact with PB2 and that all linker-insertion mutants except one at the extreme COOH end (L-746) of PB1 were also negative for viral polymerase activity. These results show that compared with complex formation of PB1 with PB2, the polymerase activity of PB1 was extremely sensitive to structural perturbation.
Enzymatic Synthesis of Self-assembled Dicer Substrate RNA Nanostructures for Programmable Gene Silencing (2018)

Enzymatic synthesis of RNA nanostructures is achieved by isothermal rolling circle transcription (RCT). Each arm of RNA nanostructures provides a functional role of Dicer substrate RNA inducing sequence specific RNA interference (RNAi). Three different RNAi sequences (GFP, RFP, and BFP) are incorporated within the three-arm junction RNA nanostructures (Y-RNA). The template and helper DNA strands are designed for the large-scale in vitro synthesis of RNA strands to prepare self-assembled Y-RNA. Interestingly, Dicer processing of Y-RNA is highly influenced by its physical structure and different gene silencing activity is achieved depending on its arm length and overhang. In addition, enzymatic synthesis allows the preparation of various Y-RNA structures using a single DNA template offering on demand regulation of multiple target genes.
9-2: Optical Compensation Method for Wide Viewing Angle IPS LCD Using a Plastic Substrate (2016)

The problem of a sheet LCD using plastic substrates is the narrow viewing angle of the large retardation of typical plastic materials. We have developed the optical compensation and a new process for plastic IPS-LCD with wide viewing angle.
COAST: A Connected Open plAtform for Smart objecTs (2015)

Quick reactions and rescues are critical requirements in disaster and emergency management. However, the decision on how to react should be taken based on the correct judgment on the disaster situation. Nowadays ICT plays a pivotal role in the decision-making in disasters management. Particularly, the IoT technology is indispensable for information collection and analysis. Despite the rapid development in the ICT domain, the real-time analysis and response in certain emergency is still impossible. This is mainly due to the lack of computation power of thin smart objects and the vertical isolation among IoT applications. In this work, we will introduce the Connected Open plAtform for Smart objecTs (COAST) that gives smart objects, such as robots, drones and smartphones, the capability to autonomously negotiate and deploy additional resources on itself, on other objects or in the cloud. The overall goal of the COAST platform is to give the capability to smart object applications to self-adapt to the runtime context by providing an interoperable platform for real-time discovery, negotiation and on-the-fly allocation of additional resources. These resources can be provided by remote sensors, by on-demand deployment of additional - possibly 3rd party - services on the same or another smart object, or by outsourcing computation to edge cloud infrastructure tailored for high-performance and real-time computation. COAST provides the necessary platform services supporting run-time adaptation, monitoring, big data analytics. To allow the secure deployment of 3rd party application components on smart objects, the COAST provides a novel virtualization layer that supports high-performance execution through hardware accelerators. Expected performance will be reported to highlight the benefits of introducing such a platform to the IoT services in disaster management.
Glycerol carbonate as green solvent for pretreatment of sugarcane bagasse (2013)

Acidified GC alone was a more effective solvent for pretreatment of sugarcane bagasse than acidified EC alone. The higher glucose yield obtained with GC-pretreated bagasse is possibly due to the presence of one hydroxyl group in the GC molecular structure, resulting in more significant biomass delignification and defibrillation, though both solvent pretreatments reduced bagasse particles to a similar extent. The maximum glucan digestibility of GC/glycerol systems was less than that of EC/EG systems, which is likely attributed to glycerol being less effective than EG in biomass delignification and defibrillation. Acidified AC/AG solvent systems were more effective for pretreatment of lignin-containing biomass than MCC.
Displacement Study on a Vancomycin-Based Stationary Phase Using N-acetyl-D-Alanine as a Competing Agent (2002)

The analysis of the binding data of D,L-dansyl amino acids on a vancomycin stationary phase is investigated in relation to the addition of N-acetyl-D-alanine in the mobile phase. This eluent additive acts as a specific competing agent for the aglycone pocket of the immobilized chiral selector. A model taking into account both stereoselective and nonstereoselective interactions between the solutes and the stationary phase is used to fit the experimental data. From the results, the theoretical approach is considered to be adequate to describe the competing agent dependence on solute retention. To the best of our knowledge, this report constitutes the first example of a displacement study on a macrocyclic antibiotic stationary phase. This work shows that dansyl amino acids bind to the active aglycone pocket of the selector and that this interaction is enantioselective. The results also demonstrate that additional enantioselective sites at the vancomycin surface are involved in the chiral discrimination of these solutes.
Polymicrobial sepsis disrupts normal neutrophil extracellular matrix protein interactions. (1992)

The purpose of this study was to examine how intra-abdominal sepsis and extracellular matrix proteins (fibronectin, laminin) affect adherent polymorphonuclear leukocyte (PMN) function. Two groups of swine were studied: Group I (n = 5) underwent sham laparotomy; Group II (n = 8) underwent cecal ligation and incision. PMN adherent to either fibronectin (F) or laminin (L) had increased candicidal activity over buffer (B) by Group I but not by post-operative day 8 Group II PMN. (Percent specific release 51Cr-Group I--35.00, 68.25, 64.75% for B, F, and L; P less than 0.001 comparing B vs. F or L; Group II--14.25, 12.50, 12.75% for B, F, and L; P = NS comparing B vs. F or L.) To determine the mechanism for this finding, PMN priming was then assessed by evaluating both PMN adherence to extracellular matrix proteins and the cell surface expression of CR1/CR3 by using sheep RBC opsonized with C3b or C3bi. PMN activation was assayed by using MTT-Formazan, myeloperoxidase, and hypochlorous acid (HOCl) production. Fibronectin and laminin increased PMN adherence and CR1/CR3 expression over buffer by Group I and Group II animals. Fibronectin and laminin increased MTT-Formazan, myeloperoxidase, and HOCl production over buffer by Group I PMN but not POD 8 Group II PMN. These results suggest that untreated intra-abdominal sepsis partially abrogates the effect of extracellular matrix proteins on PMN function; in particular, the activation but not priming of adherent PMN by extracellular matrix proteins is reduced in this clinical situation.
A New ATPG Method for Efficient Capture Power Reduction During Scan Testing (2006)

High power dissipation can occur when the response to a test vector is captured by flip-flops in scan testing, resulting in excessive JR drop, which may cause significant capture-induced yield loss in the DSM era. This paper addresses this serious problem with a novel test generation method, featuring a unique algorithm that deterministically generates test cubes not only for fault detection but also for capture power reduction. Compared with previous methods that passively conduct X-filling for unspecified bits in test cubes generated only for fault detection, the new method achieves more capture power reduction with less test set inflation. Experimental results show its effectiveness.
A multistage multi-carrier CDMA receiver with enhanced interference suppression (2002)

A multistage multi-carrier CDMA (MSMC-CDMA) receiver with enhanced multiple access interference (MAI) suppression is proposed. MC-CDMA is based on a combination of CDMA and orthogonal frequency division multiplexing (OFDM) techniques. The design of the receiver involves the following procedure. First, a set of adaptive matched filters (MF) is constructed to collect multipath signals with different time delays. The tap weights of each MF are determined in accordance with the linearly constrained minimum variance (LCMV) criterion so that strong MAI can be effectively suppressed. Second, channel estimation and signal reconstruction are accomplished by exploiting pilot symbols, decision-directed symbols and the signal's signature. Finally, a decision-directed RAKE receiver gives the estimate of the signal, which is then subtracted from the data sent to the next stage. The proposed receiver can be used in a reverse link system with time-multiplexed pilot symbols, and achieves nearly the performance of the optimal maximum SINR (MSINR) receiver.
