Automatic Mood Detection from Acoustic Music Data (2003)

Dopaminergic medication in Parkinson's disease has been proposed to improve cognitive processing by modulating the severely depleted dorsal striatum, while impairing reward processing by modulating the relatively intact ventral striatum. However, there is no direct (neural) evidence for this hypothesis. Here we fill this gap by scanning Parkinson's disease patients (n=15) ON and relatively OFF their dopaminergic medication using functional magnetic resonance imaging. During scanning, patients performed a task that enabled the simultaneous measurement of task-switching and reward-related processing. Brain-behavior correlations revealed that medication-related increases (ON-OFF) in switch-related BOLD signal (switch-repeat) in the dorsomedial striatum were associated, on an individual basis, with improvements in task-switching (i.e. a decreased switch cost). Conversely, medication-related increases (ON-OFF) in reward-related BOLD signal (high-low) in the ventromedial striatum were associated, on an individual basis, with impairments in performance in anticipation of reward (i.e. an increased reward cost). Linear regression analyses demonstrated that the positive relationship between medication-related changes in BOLD and the reward cost was unique to the ventromedial striatum, whereas the negative relationship between medication-related changes in BOLD and the switch cost was not unique to the dorsomedial striatum. These findings extend the dopamine overdose hypothesis, according to which dopamine-induced changes in dorsal and ventral striatal processing lead to cognitive improvement and impairment respectively.

Effectiveness of Visual Selection for Early Clonal Generation Seedlings of Potato (1975)

Random samples of 20 F 1 potato ( Solanum tuberosum L.)seedlings from each of 25 crosses were planted as single‐hill lots. Tubers were harvested, and each clone was planted again as a single‐hill lot and a 10‐hill lot. Seven selectors independently scored the dug tubers for acceptability and measurements were recorded for five important characteristics (maturity, tuber appearance, average weight of marketable tubers, number of marketable tubers, and number of small tubers) which were considered to have a causal effect on visual decision making. Analyses of data derived from the three experiments revealed that the correlation between experiments was low for visual scores of individual clones and moderate to high for mean visual scores of crosses. Two reasons were suggested to explain the poor efficiency of visual discrimination among individual clones: 1) the influential trait had poor correlations between experiments, and 2) the different pattern and degree of segregation of the influential traits among crosses caused the selectors to switch their attention to different traits when examining clones within different crosses. On a cross mean basis, tuber appearance and average weight of marketable tubers appeared to be more influential than other traits on the mean visual score of crosses.

Bode's integral theorem for discrete-time systems (1990)

A paper by Bode has shown the limitations of using a feedback structure in terms of an integral constraint on the sensitivity function for open-loop stable continuous-time systems. The paper by Mohtadi examines and derives equivalent results for discrete-time feedback systems. These integral constraints also provide some guidelines regarding the philosophy of feedback design specifically for sampled-data systems. For example, it is shown that, for all sampled-data control systems, there is a maximum sampling frequency, beyond which little improvement in performance is gained.
Feasibility of Intratumoral Confocal Microscopy under Endoscopic Ultrasound Guidance (2012)

The primary goal of this study was to develop descriptive image interpretation criteria and a classification of endoscopic ultrasound-confocal microscopy (EUS-CM) findings in pancreatic masses and lymph nodes through a review of prospectively obtained EUS-CM videos from proven malignant and benign cases, and to propose diagnostic criteria for predicting malignancy. The material used was a 19-G EUS-needle in which the stylet was replaced by the confocal mini-probe. The mini-probe pre-loaded in the EUS-needle was guided endosonographically in the target then the mini-probe was pushed under EUS guidance into the lesion. Eleven patients mean age 62.3 years underwent EUS for the staging of a pancreatic mass (3 cystic and 4 solid) or for the diagnosis of celiac and/or mediastinal LN (n = 4). Benign intraductal papillary mucinous neoplasm (IPMN) was characterized by the aspect of finger-like projections which correspond to the villous changes of intestinal IPMN type. In pancreatic adenocarcinomas, EUS-CM found vascular leakage with irregular vessels with leakage of fluorescein into the tumor, large dark clumps which correspond to humps of malignant cells. Inflammatory lymph nodes were characterized by the presence of diffuse small cells into a homogeneous stroma with a normal vascularization. At the opposite, EUS-CM showed in malignant lymph node glandular structures with dark cells, large dark clumps and an important neo-vascularization with huge leakage of fluorescein.
A Two-Phase Log-Based Fault Recovery Mechanism in Master/Worker Based Computing Environment (2009)

The master/worker pattern is widely used to construct the cross-domain, large scale computing infrastructure. The applications supported by this kind of infrastructure usually features long-running, speculative execution etc. Fault recovery mechanism is significant to them especially in the wide area network environment, which consists of error prone components. Inter-node cooperation is urgent to make the recovery process more efficient. The traditional log-based rollback recovery mechanism which features independent recovery cannot fulfill the global cooperation requirement due to the waste of bandwidth and slow application data transfer which is caused by the exchange of a large amount of logs. In this paper, we propose a two-phase log-based recovery mechanism which is of merits such as space saving and global optimization and can be used as a complement of the current log-based rollback recovery approach in some specific situations. We have demonstrated the use of this mechanism in the Drug Discovery Grid environment, which is supported by China National Grid. Experiment results have proved efficiency of this mechanism.
Mobility management in 4G wireless heterogeneous networks (2008)

L évolution des technologies réseaux sans fils et cellulaires associée au développement des terminaux mobiles est en train d ouvrir de nouvelles perspectives pour les usagers à savoir un accès universel et ininterrompu au réseau, aux informations et aux services. La capacité à fournir un accès ubiquitaire et une mobilité transparents à travers des réseaux hétérogènes permettra d'enrichir l'expérience des usagers. Néanmoins, la mise en place de cet environnement pose des challenges de recherche extrêmement importants que cette thèse a comme pour objectif d aborder. Elle présente une ensemble de solutions qui contribuent à l'évolution de la convergence de technologies en améliorant différentes aspects du handover vertical, de la synergie entre technologies cellulaires et sans fils afin que la mobilité sans couture devienne une réalité. La première partie de la thèse examine le rôle de l'utilisateur dans la gestion de la mobilité inter-système. Nous montrons comment les utilisateurs avec leurs terminaux mobiles intelligents peuvent surmonter certains obstacles dans la gestion de handover vertical et améliorer ses performances. Une solution de la mobilité contrôlée par le terminal d'usager a été proposée. Elle consiste en un nouveau mécanisme de sélection de réseaux d'accès avec de nouvelles fonctions d'utilité. Le terminal est en mesure de contrôler ses interfaces radio pour optimiser la consommation d'énergie ainsi que de contrôler l'initiation et la préparation de handover pour assurer des services sans interruption. Une nouvelle méthode de prédiction du handover pour assister à la préparation d un basculement sans couture est proposée. Dans la deuxième partie de la thèse, il s agit d aborder le rôle du contrôle du réseau dans la gestion de la mobilité inter-système. Une solution d'interfonctionnement entre UMTS et WiMAX, qui comprend l'architecture d'intégration, les procédures exactes de handover, la mesure inter-système et le chevauchement nécessaire entre deux cellules avoisinantes pour assurer un handover sans couture est proposée. Pour faciliter l'interfonctionnement et l'itinérance (roaming) entre différents réseaux d accès indépendamment et sans accords directes entre opérateurs, des plateformes intermédiaires ont été proposées. Finalement, une contribution finale qui consiste à introduire une nouvelle définition de la charge, un nouvel indice de l'équilibrage de charge et un algorithme de répartition de charge qui permettent de définir une solution unifié de gestion de la mobilité dans un contexte de réseaux hétérogènes.
Control of post‐harvest brown rot on nectarine by <i>Epicoccum nigrum</i> and physico‐chemical treatments (2007)

Abstract Post‐harvest physico‐chemical treatments—water at 40 °C or 60 °C (HW), and sodium bicarbonate at 1 or 2.5% (SBC) at 20, 40 and 60 °C—were tested on peaches and nectarines in order to control brown rot caused by Monilinia spp. and to select the best physico‐chemical treatment to be used in combination with pre‐harvest applications of the biological control agent Epicoccum nigrum (ATCC number 96794). Experiments were carried out in France, Italy and Spain in order to test different experimental conditions. Monilinia rot was reduced in peach and nectarine treated with HW (40 °C for 2 min) in all three countries, the percentage of rot reduction was similar for France, Italy and Spain (over 40%). A synergistic effect between HW at 40 °C during 150 s or at 60 °C during 20 s and SBC was observed in all three countries. After preliminary experiments post‐harvest treatment of HW (60 °C) + SBC (1%) during 20 s was selected to combine it with field treatments. Pre‐harvest treatments with fungicide or E. nigrum did not reduce brown rot in any country. However, pre‐harvest treatments with E. nigrum , chemical fungicide, and their integration followed by post‐harvest physico‐chemical treatment significantly reduced Monilinia rot compared to pre‐harvest untreated fruits followed by post‐harvest physico‐chemical treatment in Italy (over 70%). Post‐harvest treatments with E. nigrum were also tested in Italy on natural and artificial infections in nectarine over 3 years. E. nigrum , as fresh or formulated cells, at a concentration of 10 8 conidia mL −1 were effective, significantly reducing the incidence of brown rot compared to control, both under artificial and natural infection, from 43 to 100%.

Reducing scanning latency in WiMAX enabled VANETs (2014)

WiMAX offers many promising features such as high data rate, low deployment cost and a wide coverage, which makes it suitable for Vehicular Ad hoc NETworks (VANETs). However, a smooth handover for various real-time applications supported by VANETs is a challenge. In this paper, we therefore propose an efficient network assisted handover scheme which reduces the scanning latency faced by vehicles during handover process. During handover, a serving RSU will perform the selection and pre-authorization of a target RSU for a vehicle based on its velocity. In addition, the serving RSU also provides the vehicle with channel information and estimated time to start scanning in order to get associated with its target RSU. Through NS-2 simulations, it is observed that our proposed scheme efficiently reduces the overall scanning delay and iterations commonly faced by vehicles.
A electronically steerable radiator and reflector array antenna based on Three-Dimensional Frequency Selective Structure (2012)

A novel electronically steerable radiator and reflector array (ESRRA) antenna is proposed. The antenna based on Three-Dimensional(3-D) Frequency Selective Structure(FSS), which is a recent development, composed of a dipole antenna and number of conformal Three-Dimensional Frequency Selective Structure units and this is the first time that 3-D FSS applied to the scanning antenna which played a good performance. The 3-D FSS units are conformed as a cylindrical around the dipole antenna varactors loaded in 3-D FSS are biased by a 0-10 V continuously variable voltage, that make 3-D FSS units band-stop frequency change from 2.26GHz to 3.7GHz, which means the wave of central frequency (2.26 GHz) could be controlled passing through or reflecting. The Radiation beam changed within the region of 15 degrees can be achieved by adjusting the phase and amplitude to realize more accuracy beam scanning, so this antenna produce a full range of sweeping in the omnidirections and can realize Multi-beam scanning function. Simulation results show that the gain of the antenna can be promoted to 4.4 dB, which is 2dB higher than the gain of dipole antenna and it can be controlled to get beam scanning.
Multi-camera interference cancellation of time-of-flight (TOF) cameras (2015)

In the applications based on depth, multiple TOF cameras are often required to capture the same scene. But if multiple cameras operate simultaneously on the same frequency, they interfere with each other. The multi-camera interference causes a lot of errors in depth measurement. The depth quality is severely reduced, which limits the application of TOF cameras and needs to be resolved. In this paper, a multi-camera interference model is presented. The interference signal for multiple frames is proved to be an ergodic and wide-sense stationary stochastic process. The least square estimation of noninterference signal is proposed to remove the multi-camera interference. The results of experiments prove the approach can recover the depth and amplitude information of multiple TOF cameras from the severe interference.
Marination to Improve Functional Properties and Safety of Poultry Meat (2007)

The most commonly used poultry marinades include salt and sodium tripolyphosphate, which have been shown to increase meat yield and water-holding capacity, as well as improve color and texture. Recently, several poultry further-processing facilities have begun using more acidic (pH ˜4) type marinades such as sodium lactate, sodium citrate, and sodium diacetate (alone or in combination) to combat the growth of Listeria monocytogenes in further-processed meat loaves. Because the acidic marinades currently used in turkey further-processing have a low pH (˜4) compared with the previously used salt and sodium tripolyphosphate (˜pH 9), these marinades may cause meat quality problems. This review paper will discuss aspects of poultry food safety and meat quality and how acidic marinades can be used to improve safety, specifically by controlling L. monocytogenes growth, and how they affect quality of the meat products. Current industry practices will be discussed and reviewed.
Resonance Ionization Spectroscopy and its Application (1994)

Resonance ionization spectroscopy and its combination with mass spectrometry offer very high sensitivity and selectivity. The application of several variants of resonance ionization mass spectroscopy to the study of nuclear ground state properties and trace analysis of radioactive isotopes in the environment is discussed as well as the inverse process, i.e. the laser induced recombination, of bare heavy ions stored at relativistic energies in storage rings.
Some Distinctive Characteristics of the Alkaline Phosphatase of <i>Serratia marcescens</i> (1975)

A mutant strain of Serratia marcescens produces a constitutive enzyme (phosphatase F), which differs from the alkaline phosphatase of Escherichia coli in the following characteristics: one enzyme species with higher mobility on electrophoresis, less heat stability, no rapid reactivation following exposure to high hydrogen ion concentrations, no hybridization with E. coli enzyme in vitro, little activation at increased ionic strength, greater sensitivity to EDTA inhibition, and no cross reaction of rabbit anti-serum with the E. coli enzyme.
Restoration of arbitrarily warped document images based on text line and word detection (2007)

This paper presents a novel technique for efficient restoration of arbitrarily warped document images. Our aim is to recover document images that are mainly bounded volumes captured by a digital camera and suffer from non-linear warp. The proposed technique is applied on gray scale document images and is based on several distinct steps: an adaptive document image binarization, a text line and word detection, a first draft binary image dewarping based on word rotation and shifting and, finally, a complete restoration of the original grayscale warped image guided by the binary dewarping result. In this paper, we present a detailed description of the proposed technique as well as the implementation results for each step of our methodology. The experimental results on several arbitrarily warped documents indicate the effectiveness of the proposed technique.
Marburg and Ebola virus infections in laboratory non-human primates: a literature review. (2000)

A total of 23 Marburg and Ebola virus outbreaks causing viral hemorrhagic fever has been reported among humans and monkeys since the first outbreak in Marburg, Germany in 1967. Most of the 1,100 human cases, with nearly 800 deaths, developed in Africa due mainly to direct and intimate contact with infected patients. Few human cases have developed after contact with non-human primates used for various scientific purposes. However, adequate quarantine should be applied to prevent human infections not only due to Marburg and Ebola viruses, but also to other infective agents. By following proper guidelines, the filovirus infection risk for people working with non-human primates during quarantine exists, but is minimal. There seems to be little risk for filovirus infections after an adequate quarantine period. Therefore, non-human primates can be used as laboratory animals, with little risk of filovirus infections, provided adequate precautions are taken.
Inference of edit costs using parametric string matching (2003)

String matching is a useful concept in pattern recognition that is constantly receiving attention from both theoretical and practical points of view. The authors propose a generalized version of the string matching algorithm by Wagner and Fischer (1974). It is based on a parametrization of the edit cost. The authors assume constant cost for any delete and insert operation, but the cost for replacing a symbol is given as a parameter r. For any two given strings A and B, the algorithm computes the edit distance of A and B in terms of the parameter r. The authors give the new algorithm and study some of its properties. Its time complexity is O(n/sup 2/.m), where n and m are the lengths of the two strings to be compared and n<or=m. The authors also discuss potential applications of the new string distance to pattern recognition. Finally, some experimental results are presented.<<ETX>>
The reminder bracelet (2000)

We are investigating new ways of conveying event notifications from mobile devices to their users. Our ambition has been to explore non-intrusive, or subtle ways of notifying users, to hide the technology and make room for aesthetic considerations. We argue that there is need for new ways of attracting a user's attention, while at the same time not disturbing other people. We have built a notification tool, the Reminder Bracelet, that is worn on the wrist and connected to a PDA. It notifies its user of scheduled events in a subtle and silent manner using light, color and patterns. Initial evalutations have shown that in a number of situations, the bracelet was preferred to the alert sound of a PDA or a mobile phone.
Intellectual property: basic forms (2001)

Intellectual Property typically refers to patents, copyrights, trade secrets and trademarks that are used to protect the innovative efforts of an organization. Patents protect certain novel, useful and non-obvious inventions. Copyright protect particular expressions of an idea, though not the idea itself. Trade secrets protect information that has value by virtue of not being generally known of readily ascertainable by others. Trademarks protect certain goodwill associated with the organization's goods and services.

A Study of Language Model for Image Retrieval (2009)

Recently, various language model approaches have been proposed in the information retrieval realm, with their promising performances in general document and Web page retrieval applications. Based on these achievements, in this paper, we investigate and discuss whether language model approaches can be adapted to content based image retrieval (CBIR), based on the ¿bag of visual words¿ image representation. A critical element of language model estimation is smoothing, which adjusts the maximum likelihood estimation to overcome the data sparseness problem. Therefore, we perform extensive studies over different smoothing methods, strategies, and parameters, by showing their impacts to the retrieval performances. Experiments are performed over two popular image retrieval databases, together with some insightful conclusions to facilitate the adaptation of language model approaches to CBIR.
