Image Quality and Minutiae Count Comparison for Genuine and Artificial Fingerprints (2007)

The vulnerabilities of biometric sensors have been discussed extensively in the literature and popularized in films and television shows. This research examines the image quality of an artificial print as compared to a genuine finger, and examines the characteristics of the two, including minutiae counts and image quality, as repeated samples are taken.
Phosphatidylcholine transfer protein from bovine liver contains highly unsaturated phosphatidylcholine species (1996)

The phosphatidylcholine transfer protein (PC-TP) from bovine liver contains one molecule of non-covalently bound PC. In order to gain more insight into the physiological function of PC-TP, PC was extracted from bovine liver PC-TP and its molecular species composition identified by fast atom bombardment mass spectrometry. The prevailing molecular species were C18:0/C18:1-, C18:0/C18:2-, C18:0/C20:4-, C18:0/20:5- and C18:0/C22:5-PC accounting for 85% of the PC species present. This molecular species composition is not representative for what is present in bovine liver where these species account for 43% of the total PC content [Montfoort et al. (1971) Biochim. Biophys. Acta 231, 335-342]. Another striking observation is that PC species carrying a palmitoyl chain at the sn-1 position are nearly absent, despite these species being abundantly present in bovine liver. This study suggests that PC-TP could play a role in the metabolism of highly unsaturated, stearoyl-containing PC species.
GTP Security in 3G Core Network (2010)

Nowadays, 3G netowrk plays a very important role in mobile communication system. But the security concern of such network, especially the core network, is far from being satisfied. GPRS Tunnel Protocol(GTP), which is one of the key protocols in the core network, is quite vulnerable to attacks in the flat, full IP environment. Therefore solving such problem properly is very urgent and important for the operation of 3G network. In this paper, a security analysis of GTP is presented, a defense solution for these security threats and an event-based description language are also proposed. The experiment result shows the potential of our solution.
Deterministic Guided LiDAR Depth Map Completion (2021)

Accurate dense depth estimation is crucial for autonomous vehicles to analyze their environment. This paper presents a non-deep learning-based approach to densify a sparse LiDAR-based depth map using a guidance RGB image. To achieve this goal the RGB image is at first cleared from most of the camera-LiDAR misalignment artifacts. Afterward, it is over segmented and a plane for each superpixel is approximated. In the case a superpixel is not well represented by a plane, a plane is approximated for a convex hull of the most inlier. Finally, the pinhole camera model is used for the interpolation process and the remaining areas are interpolated. The evaluation of this work is executed using the KITTI depth completion benchmark, which validates the proposed work and shows that it outperforms the state-of-the-art non-deep learning-based methods, in addition to several deep learning-based methods.
Poorer Drinking Outcomes with Citalopram Treatment for Alcohol Dependence: A Randomized, Double‐Blind, Placebo‐Controlled Trial (2015)

This trial does not support the use of citalopram in the treatment of alcohol dependence. The results suggest that the use of SSRIs among depressed and nondepressed alcohol-dependent individuals early in recovery, prior to the onset of abstinence, may be contraindicated.
A Contrast-Sensitive Reversible Visible Image Watermarking Technique (2009)

A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the original image. We transparently reveal the watermark image by overlapping it on a user-specified region of the host image through adaptively adjusting the pixel values beneath the watermark, depending on the human visual system-based scaling factors. In order to achieve reversibility, a reconstruction/recovery packet, which is utilized to restore the watermarked area, is reversibly inserted into non-visibly-watermarked region. The packet is established according to the difference image between the original image and its approximate version instead of its visibly watermarked version so as to alleviate its overhead. For the generation of the approximation, we develop a simple prediction technique that makes use of the unaltered neighboring pixels as auxiliary information. The recovery packet is uniquely encoded before hiding so that the original watermark pattern can be reconstructed based on the encoded packet. In this way, the image recovery process is carried out without needing the availability of the watermark. In addition, our method adopts data compression for further reduction in the recovery packet size and improvement in embedding capacity. The experimental results demonstrate the superiority of the proposed scheme compared to the existing methods.
Lithofacies determination from wire-line log data using a distributed neural network (2002)

A distributed neural network, running on a large transputer-based parallel computer, was trained to identify the presence of the main lithographical facies types in a particular oil well, using only the readings obtained by a log probe. The resulting trained network was then used to analyse a variety of other wells, and showed only a small decrease in accuracy of identification. Geologists classify well structures using rock and fossil samples in addition to the log data that was given to the network. Results are given here for the accuracy with which the learned network agreed with analyses performed by geologists. The study was then extended into two more areas, firstly to investigate the network's success in predicting physical attributes of the rocks, e.g. porosity and permeability, and secondly to investigate the ability of similar networks to isolate particular geological features.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Modelling Annotator Bias with Multi-task Gaussian Processes: An Application to Machine Translation Quality Estimation (2013)

Annotating linguistic data is often a complex, time consuming and expensive endeavour. Even with strict annotation guidelines, human subjects often deviate in their analyses, each bringing different biases, interpretations of the task and levels of consistency. We present novel techniques for learning from the outputs of multiple annotators while accounting for annotator specific behaviour. These techniques use multi-task Gaussian Processes to learn jointly a series of annotator and metadata specific models, while explicitly representing correlations between models which can be learned directly from data. Our experiments on two machine translation quality estimation datasets show uniform significant accuracy gains from multi-task learning, and consistently outperform strong baselines.
Behavior of a Bayesian adaptation method for incremental enrollment in speaker verification (2002)

Classical adaptation approaches are generally used for speaker or environment adaptation of speech recognition systems. In this paper, we use such techniques for the incremental training of client models in a speaker verification system. The initial model is trained on a very limited amount of data and then progressively updated with access data, using a segmental-EM procedure. In supervised mode (i.e. when access utterances are certified), the incremental approach yields equivalent performance to the batch one. We also investigate on the impact of various scenarios of impostor attacks during the incremental enrollment phase. All results are obtained with the Picassoft platform-the state-of-the-art speaker verification system developed in the PICASSO project.
Deep Feature Consistent Deep Image Transformations: Downscaling, Decolorization and HDR Tone Mapping (2017)

Building on crucial insights into the determining factors of the visual integrity of an image and the property of deep convolutional neural network (CNN), we have developed the Deep Feature Consistent Deep Image Transformation (DFC-DIT) framework which unifies challenging one-to-many mapping image processing problems such as image downscaling, decolorization (colour to grayscale conversion) and high dynamic range (HDR) image tone mapping. We train one CNN as a non-linear mapper to transform an input image to an output image following what we term the deep feature consistency principle which is enforced through another pretrained and fixed deep CNN. This is the first work that uses deep learning to solve and unify these three common image processing tasks. We present experimental results to demonstrate the effectiveness of the DFC-DIT technique and its state of the art performances.
Development of a phoswich detector to detect neutrons and charged particles for space application (1998)

We have developed a new phoswich detector consisting of an NE213 liquid scintillator surrounded by an NE115 plastic scintillator to measure high energy neutron spectra accurately in a charged-particle mixed field. Differences in the decay time constants of light outputs from the two scintillators make it possible to separate charged-particle-induced and neutron-induced pulses. Experiments were carried out at the RIKEN and at the NIRS cyclotrons. This detector was found to be able to discriminate neutron and gamma-ray events from external-proton events. This detector will be useful to measure high energy neutrons in space.

Tourette's syndrome. (2008)

Tourette's syndrome is a movement disorder most commonly seen in school-age children. The incidence peaks around preadolescence with one half of cases resolving in early adulthood. Tourette's syndrome is the most common cause of tics, which are involuntary or semivoluntary, sudden, brief, intermittent, repetitive movements (motor tics) or sounds (phonic tics). It is often associated with psychiatric comorbidities, mainly attention-deficit/hyperactivity disorder and obsessive-compulsive disorder. Given its diverse presentation, Tourette's syndrome can mimic many hyperkinetic disorders, making the diagnosis challenging at times. The etiology of this syndrome is thought to be related to basal ganglia dysfunction. Treatment can be behavioral, pharmacologic, or surgical, and is dictated by the most incapacitating symptoms. Alpha2-adrenergic agonists are the first line of pharmacologic therapy, but dopamine-receptor-blocking drugs are required for multiple, complex tics. Dopamine-receptor-blocking drugs are associated with potential side effects including sedation, weight gain, acute dystonic reactions, and tardive dyskinesia. Appropriate diagnosis and treatment can substantially improve quality of life and psychosocial functioning in affected children.
[Psychotherapy of depression]. (1990)

The combination of psychopharmacology and psychotherapy produced the best results in the treatment of depression. These two modalities can be used simultaneously or alternatively. Three forms of psychotherapy are most widely used and effective in depressed patients: interpersonal therapy, cognitive therapy and behavioural therapy.

Classification of movement patterns in skiing (2013)

In cross country skiing there are different skiing techniques, known as gears. For professional skiers it is useful to analyze a ski session with respect to the gears used in different parts of the track. We have developed a statistical machine learning method that uses data from accelerometers in e.g. a mobile phone placed on the chest of a skier to classify the gears used. The statistical model used is based on a Markov chain of multivariate Gaussian distributions. The same model can in addition to classification be used for anomaly detection and unsupervised clustering of skiing movements. The method is evaluated on real data from elite skiers collected during a training race.

Optimized Multiagent Routing for a Class of Guidepath-Based Transport Systems (2018)

This paper presents a heuristic algorithm for minimizing the makespan required to route a set of agents inhabiting a shared guidepath network from their initial locations to their respective destinations while observing a set of regulations that seek to ensure the safety and the integrity of the generated traffic. From an application standpoint, the presented developments are motivated by the traffic coordination challenges that arise in the context of many automated unit-load material handling systems and also in the transport of the ionized atoms that takes place in the context of quantum computing. From a methodological standpoint, our developments constitute a customization of the general “local-search” framework of combinatorial optimization theory to the traffic management problem that is considered in this paper. Hence, the presented results include a rigorous characterization of the considered problem and its solution space, detailed algorithms for the construction of the necessary initial solutions and the improving step for the pursued search, a complexity analysis of these algorithms, and a set of computational experiments that reveal and assess the computational efficiency of the presented algorithms and the efficacy of the derived solutions. The paper concludes with some suggestions for potential extensions of the presented results.
A Schottky/2-DEG varactor diode for millimeter and submillimeter wave multiplier applications (1992)

A new Schottky diode is investigated for use as a multiplier element in the millimeter and submillimeter wavelength regions. The new diode is based on the Schottky contact at the edge of a 2-dimensional electron gas (2-DEG). As a negative voltage is applied to the Schottky contact, the depletion layer between the Schottky contact and the 2-DEG expands and the junction capacitance decreases, resulting in a nonlinear capacitance-voltage characteristic. In this paper, we outline the theory, design, fabrication, and evaluation of the new device. Recent results include devices having cutoff frequencies of 1 THz and above. Preliminary multiplier results are also presented.
A New Centralized Adaptive Underfrequency Load Shedding Controller for Microgrids Based on a Distribution State Estimator (2016)

This paper presents a new centralized adaptive underfrequency load shedding controller that is integrated with a distribution state estimator to improve the frequency stability of islanded microgrids. While underfrequency load shedding is a well-established corrective emergency frequency-control action, it is not entirely suitable for use in microgrids with low inertia and a limited number of measurement devices. The novel centralized controller presented in this paper overcomes these challenges by incorporating a distribution state estimator to estimate the power consumption of the demand. In parallel to this, the actual active power imbalance in the microgrid is estimated by simultaneously monitoring the system frequency and its rate of change. The centralized controller uses these two variables to determine the correct amount of load to be shed. The performance of the proposed controller has been validated using computer simulations of the actual distribution network in Malaysia. These simulation results show the effectiveness of the proposed centralized controller for preventing power system instabilities, which might lead to cascading outages and even a complete blackout in microgrids that have been disconnected/islanded, from the main grid.
Container Orchestration by Kubernetes for RDMA Networking (2019)

With the widespread usage of containerized virtualization in data centers and clouds, it is important to enabling high-throughput and zero-copy data transfer between those containers. Remote Direct Memory Access (RDMA) allows bypassing the kernel for packet processing by offloading it to specific RDMA-enabled NICs. The existing solutions enabling RDMA with containers are either based on custom container orchestrators (e.g., FreeFlow) or lack the ability for the control plane to manage the underlying RDMA traffic (e.g., Kubernetes RDMA plug-in via SR-IOV). The work in this paper builds off of previous work in Kubernetes to make an architecture that allows control over bandwidth requirements of RDMA within a Kubernetes cluster.
Peptides-Staple Method Development and Its Application in Cancer Therapy (2014)

Detyrosination of Tubulin Regulates the Interaction of Intermediate Filaments with Microtubules In Vivo via a Kinesin-dependent Mechanism (1999)

Posttranslationally modified forms of tubulin accumulate in the subset of stabilized microtubules (MTs) in cells but are not themselves involved in generating MT stability. We showed previously that stabilized, detyrosinated (Glu) MTs function to localize vimentin intermediate filaments (IFs) in fibroblasts. To determine whether tubulin detyrosination or MT stability is the critical element in the preferential association of IFs with Glu MTs, we microinjected nonpolymerizable Glu tubulin into cells. If detyrosination is critical, then soluble Glu tubulin should be a competitive inhibitor of the IF-MT interaction. Before microinjection, Glu tubulin was rendered nonpolymerizable and nontyrosinatable by treatment with iodoacetamide (IAA). Microinjected IAA-Glu tubulin disrupted the interaction of IFs with MTs, as assayed by the collapse of IFs to a perinuclear location, and had no detectable effect on the array of Glu or tyrosinated MTs in cells. Conversely, neither IAA-tyrosinated tubulin nor untreated Glu tubulin, which assembled into MTs, caused collapse of IFs when microinjected. The epitope on Glu tubulin responsible for interfering with the Glu MT-IF interaction was mapped by microinjecting tubulin fragments of alpha-tubulin. The 14-kDa C-terminal fragment of Glu tubulin (alpha-C Glu) induced IF collapse, whereas the 36-kDa N-terminal fragment of alpha-tubulin did not alter the IF array. The epitope required more than the detyrosination site at the C terminus, because a short peptide (a 7-mer) mimicking the C terminus of Glu tubulin did not disrupt the IF distribution. We previously showed that kinesin may mediate the interaction of Glu MTs and IFs. In this study we found that kinesin binding to MTs in vitro was inhibited by the same reagents (i.e., IAA-Glu tubulin and alpha-C Glu) that disrupted the IF-Glu MT interaction in vivo. These results demonstrate for the first time that tubulin detyrosination functions as a signal for the recruitment of IFs to MTs via a mechanism that is likely to involve kinesin.
