Gesture segmentation in complex motion sequences (2004)

Complex human motion sequences (such as dances) are typically analyzed by segmenting them into shorter motion sequences, called gestures. However, this segmentation process is subjective, and varies considerably from one human observer to another. In this paper, we propose an algorithm called hierarchical activity segmentation. This algorithm employs a dynamic hierarchical layered structure to represent the human anatomy, and uses low-level motion parameters to characterize motion in the various layers of this hierarchy, which correspond to different segments of the human body. This characterization is used with a naive Bayesian classifier to derive creator profiles from empirical data. Then those profiles are used to predict how creators will segment gestures in other motion sequences. When the predictions were tested with a library of 3D motion capture sequences, which were segmented by 2 choreographers they were found to be reasonably accurate.
Observation of Order-Disorder Transitions in Strained-Semiconductor Systems (1985)

We report the observation of an order-disorder transition in the semiconductor strained-superlattice system GeSi/Si, which doubles the lattice periodicity in a $〈111〉$ direction. This phenomenon may be representative of a class of order-disorder transitions in strained-semiconductor systems, even when the lattice mismatch is small.
Structural analysis of acetylated hardwood lignins and their photoyellowing properties (2005)

Lignin was isolated from aspen bleached chemithermomechanical pulp by employing a mild acid hydrolysis procedure, and the extracted material was acetylated with acetic anhydride. Nuclear magnetic resonance analyses indicated that the relative ease of acetylating lignin hydroxyl groups was phenolic >> γ-side chain > α-side chain. Non-acetylated and acetylated lignins were impregnated onto cellulosic test sheets, and the photo-behavior of the lignins was examined under irradiation with two light sources, a fluorescent lamp and a black lamp. Optical reflective studies indicated acetylation efficiently inhibited the photodiscoloration of aspen bleached chemithermomechanical pulp lignin under visible and near-UV light irradiation. The photostability of the lignin was correlated to the extent of lignin acetylation. The observed photo-stabilization of acetylated lignin during light irradiation was attributed to the acetylation of phenoxy and aliphatic hydroxyl groups in lignin.Key words: green chemistry, hardwood lignin, acetylation, photo-stabilization, photoyellowing, NMR.
Proton-irradiated InAlN/GaN high electron mobility transistors at 5, 10, and 15 MeV energies (2012)

InAlN/GaN high electron mobility transistors (HEMTs) grown on SiC substrates were subjected to 5-15 MeV high energy protons with a fixed 5 × 1015 cm−2 fluence. The saturation currents and gate leakage currents of all the proton-irradiated InAlN/GaN HEMTs were degraded. Proton irradiation at lower energy was found to degrade the direct current (DC) current-voltage (I-V) characteristics more severely than higher-energy irradiation, because the energy loss component of the lower energy protons was larger than those of higher-energy protons in the vicinity of the 2-dimensional electron gas conducting channel. Our experimental results were consistent with stopping and range of ions in matter simulation results of the energy deposition profile by the protons.
An email classification model based on rough set theory (2005)

The communication via email is one of the most popular services of the Internet. Emails have brought us great convenience in our daily work and life. However, unsolicited messages or spam, flood our email boxes, which results in bandwidth, time and money wasting. To this end, this paper presents a rough set based model to classify emails into three categories - spam, no-spam and suspicious, rather than two classes (spam and non-spam) in most currently used approaches. By comparing with popular classification methods like Naive Bayes classification, the error ratio that a non-spam is discriminated to spam can be reduced using our proposed model.
Management of perivascular epithelioid cell tumor of the liver: A case report and review of the literature (2013)

Perivascular epithelioid cell tumor (PEComa) is a rare tumor that originates from mesenchymal tissues. Cases of PEComa in the liver are extremely rare. The present study aimed to analyze the clinical features of PEComa in the liver and discuss its management. Here we report a 25-year-old female with multiple lesions of low density with poorly defined borders in the liver, as shown by a computed tomography (CT) scan. A partial hepatectomy was proceeded and PEComa was diagnosed by immunohistochemistry. No evidence of recurrence was observed during the one year follow-up. A total of 20 patients with hepatic PEComa, including one case from the present study and 19 cases that were reported in literature between June 2001 and December 2012, were reviewed and analyzed. The mean patient age was 43.4 years (range, 25-67 years) and the cases consisted of 18 female and two male patients. The tumor size ranged between 2.0×1.6 and 15.0×12.0 cm. Of the 20 patients, nine were asymptomatic and 11 had mild to significant complaints. Immunohistochemistry plays a key role in the diagnosis of PEComa. All the cases in this study were strongly positive for human melanoma black-45. A surgical resection is the gold standard for curative intent. All the patients underwent a surgical resection and none were administered perioperative chemotherapy or radiotherapy. In total, 13 of the 14 patients with follow-up information survived during the 8-36-month follow-up period and one patient succumbed due to recurrence two years after the surgery.
Towards improved ground models for slope instability evaluations through better characterization of sediment‐hosted gas‐hydrates (2002)

ABSTRACT Recently developed effective stress‐controlled geophysical property models are used in passive‐margin slope instability analyses including simulated earthquake motion. The pressure–temperature (P–T) history of sediment‐hosted gas hydrate may significantly alter the geophysical property profile of the sediment column (e.g. metastable cement or increased pore pressures). This can result in significant amplification of earthquake ground motion, and thus seabed instability, where hydrates are present. Published studies suggest destabilization of these high‐pressure/low‐temperature sediment‐hosted hydrates could trigger catastrophic slope failures with consequent liberation of ‘greenhouse’ gases and significant effects on global climate. To provide improved ground models for slope instability analyses we are investigating the influence of P–T history on hydrate distribution in sediments through the development of laboratory techniques to enable geophysical quantification of hydrate morphology and fabric on hydrate stability.
Pattern Recognition Theory and the Launch of Modern Innate Immunity (2013)

Modern immunology in many ways is based on two major paradigms: clonal selection theory and pattern recognition theory. Both paradigms were developed initially on theoretical grounds and experimentally proven years later. The clonal selection theory provided an elegant explanation for the function
A saving solution. (1983)

Dr. Mujibur Rahaman, senior scientist at the International Center for Diarrheal Disease Research in Bangladesh, was interviewed recently in regard to oral rehydration therapy (ORT), a simple and inexpensive way of treating the loss of essential fluids and minerals that accompanies diarrhea. According to Rahaman, ORT, developed quite a while ago, is recently gaining more publicity and wider acceptance as a menas of replacing the water and electrolytes lost during acute diarrhea attack. The standard ingredients of the ORT mixture, as it is used in Bangladesh, are 3.5 gm of sodium chloride, or common salt, 2.5 gm sodium bicarbonate, and 1 gm of potassium chloride. To this one should add either 20 gm of glucose or 40 gm of sugar. This mixture should be dissolved in 1 liter of plain drinking water. Plain sugar is good enough. How much is needed depends on the severity and the duration of diarrhea. Calculations have shown that, as a rule of thumb, a child of 10-12 kg may require little more than a liter in about 24 hours. If the child has diarrhea of sufficient severity, it may require more than a liter. If the diarrhea is prolonged, it may require 2 liters. For children who are in danger of dying from dehydration, parents are warned to be watchful because further treatment and follow-up may be required. In Bangladesh a national program is currently providing the ORT in remote rural areas. At present about 1/3 of Bangladesh is covered. The national health service is distributing the solution free of cost in the villages where they have health volunteers. Although ORT is simple to make and simple to administer, one has to exercise some degree of caution with it in order to prevent infants getting dangerous symptoms like hypernatremia. ORT makes it possible for health educators to enter into the family. It is not totally correct to say water is the main problem or causative factor in producing diarrhea. In infantile diarrhea, the cause is most often a virus. Viral transmission is not associated with water. Water can affect the incidence of diarrhea in several ways. The mother's hygiene can be affected by the availability of water, not just the quality but also the quantity. A most exciting study going on now is measuring the impact of water and sanitation on diarrheal diseases.
An integrated engine health monitoring system for gas turbine aero-engines (2003)

Rolls-Royce has embarked on a strategy to incorporate a comprehensive health monitoring capability into its product and service provision of gas turbine engines. The first aircraft to benefit from this capability will be the Trent 900 powered Airbus A380. This paper describes the project that has launched this strategy and the total service it aims to provide. It outlines some of the business case issues that were considered at the inception of the project and the cost model that reflects the expected financial benefits to be accrued during the life of the project. Much of the paper is given to a description of an on-engine monitoring system for performing real-time parameter analysis and anomaly detection. Output from this system can be passed to an on-ground computer resource for further analysis to predict, classify and locate developing engine faults and anomalies. The optimum combination of the on- and off-engine computational resources is key to a technical solution that delivers a cost effective means of reducing the engine through-life operating and maintenance costs. Hence the latter part of the paper describes how these on-ground resources are integrated into the overall engine health monitoring (EHM) process and the approach taken to the partitioning of the total EHM functionality.

Design of the TruCluster multicomputer system for the Digital UNIX environment (1996)

The TruCluster product from Digital provides an available and scalable multicomputer system for the UNIX environment. Although it was designed for general-purpose computing, the first implementation is directed at the needs of large database applications. Services such as distributed locking, failover management, and remote storage access are layered on a high-speed cluster interconnect. The initial implementation uses the MEMORY CHANNEL, an extremely reliable, high-performance interconnect specially designed by Digital for the cluster system.
Responsiveness Evaluation Index for an Excavator Operation Based on Control Engineering Approach (2018)

Some industrial equipments are required by the human operation such as bulldozers, excavators and cranes. Construction machines with better operability are necessary to improve productivity. Evaluations of those operational equipments are performed to obtain the better operability by subjective evaluations of the specific evaluator at the design stage. However, subjective evaluations require the skill of evaluator or a lot of sample data. In this paper, relationships between approximated parameters expressed as a low order system and subjective evaluations are verified by using the Weber-Fechner law. The evaluated motion is the boom up motion for an excavator. The simulator for the boom motion has been made because the real excavator has the limited condition. Therefore, the evaluation is performed numerically and experimentally. Approximated system parameters for the real excavator are calculated by the genetic algorithm.
Motion Generation using Motion Mining System. (2003)

In this paper, we present a method that generates a path that has no collision with the obstacles by using the environment information, and automatically creates natural motions of characters that are confined to the path. Our Method is based on two kinds of parameters: Environment and Behavior parameters. The behavior parameters include velocity, motion status such as walking and running, and preference. The environment parameters include road and obstacles. A collision-free path is generated by these parameters, and a motion mining system generates the motion that has motion status and velocity that a user inputted while following a path. Our system predicts and avoids a collision by rulebased approach.
Multiple Exposure Fusion for High Dynamic Range Image Acquisition (2011)

A multiple exposure fusion to enhance the dynamic range of an image is proposed. The construction of high dynamic range images (HDRIs) is performed by combining multiple images taken with different exposures and estimating the irradiance value for each pixel. This is a common process for HDRI acquisition. During this process, displacements of the images caused by object movements often yield motion blur and ghosting artifacts. To address the problem, this paper presents an efficient and accurate multiple exposure fusion technique for the HDRI acquisition. Our method simultaneously estimates displacements and occlusion and saturation regions by using maximum a posteriori estimation and constructs motion-blur-free HDRIs. We also propose a new weighting scheme for the multiple image fusion. We demonstrate that our HDRI acquisition algorithm is accurate, even for images with large motion.
Intestinal Calcium Absorption and Serum Vitamin D Metabolites in Normal Subjects and Osteoporotic Patients (1979)

Intestinal calcium absorption assessed by a double-isotope method, decreased significantly with aging in 94 normal subjects (r = -0.22, P < 0.025). In 52 untreated patients with postmenopausal osteoporosis, calcium absorption was significantly lower than normal when either age or habitual calcium intake was used as a covariable (P < 0.001). Serum 25-hydroxyvitamin D (25-OH-D) and 1,25-dihydroxyvitamin D (1,25(OH)(2)D) were measured in 44 normal subjects and 27 osteoporotic patients. For all normals, calcium absorption and serum 1,25(OH)(2)D were positively correlated (r = 0.50, P < 0.001). In nonelderly normal subjects (ages 30-65 yr), dietary calcium intake correlated inversely with both calcium absorption (r = -0.39, P < 0.01) and with serum 1,25(OH)(2)D (r = -0.50, P < 0.01). Both osteoporotic patients and elderly normal subjects (ages 65-90 yr) differed from nonelderly normals in that these correlations were not present. In addition although serum 25-OH-D was normal, serum 1,25(OH)(2)D was significantly decreased in both osteoporotic patients and elderly normals (P < 0.001). In osteoporotic patients, calcium absorption increased significantly (P < 0.001) after 7 d administration of a small dose (0.4 mug/d) of synthetic 1,25(OH)(2)D(3). In osteoporotics mean serum immunoreactive parathyroid hormone was either normal (COOH-terminal assay) or low (NH(2)-terminal assay) relative to age-matched controls, and mean serum phosphate was increased. The data suggest that inadequate metabolism of 25-OH-D to 1,25(OH)(2)D contributes significantly to decreased calcium absorption and adaptation in both osteoporotics and elderly normal subjects. In patients with osteoporosis this abnormality could result from a decrease in factors that normally stimulate 1,25(OH)(2)D production, such as the decreased parathyroid hormone secretion and increased serum phosphate demonstrated in this group. In elderly subjects a primary abnormality in metabolism of 25-OH-D to 1,25(OH)(2)D, analagous to that seen in aging rats, cannot be excluded.

Phase-based harmonic/percussive separation (2014)

In this paper, a method for separation of harmonic and percussive elements in music recordings is presented. The proposed method is based on a simple spectral peak detection step followed by a phase expectation analysis that discriminates between harmonic and percussive components. The proposed method was tested on a database of 10 audio tracks and has shown superior results to the reference state-of-the-art approach.
Advance flood detection and notification system based on sensor technology and machine learning algorithm (2015)

Floods are common natural disasters that cause severe devastation of any country. They are commonly caused by precipitation and runoff of rivers, particularly during periods of excessively high rainy season. Due to global warming issues and extreme environmental effects, flood has become a serious problem to the extent of bringing about negative impact to the mankind and infrastructure. To date, sensor network technology has been used in many areas including water level fluctuation. However, efficient flood monitoring and real time notification system still a crucial part because Information Technology enabled applications have not been employed in this sector in a broad way. This research presents a description of an alert generating system for flood detection with a focus on determining the current water level using sensors technology. The system then provides notification message about water level sensitivity via Global Communication and Mobile System modem to particular authorise person. Besides the Short Message Service, the system instantaneously uploads and broadcast information through web base public network. Machine-learning algorithms were conducted to perform the classification process. Four experiments were carried out to classify flood data from normal and at risk condition in which 99.5% classification accuracy was achieved using Random Forest algorithm. Classification using Bagging, Decision Tree and HyperPipes algorithms achieved accuracy of 97.7 %, 94.6% and 89.8 %, respectively.
Two levels of interference in mouse meiotic recombination (2006)

During meiosis, homologous chromosomes (homologs) undergo recombinational interactions, which can yield crossovers (COs) or noncrossovers. COs exhibit interference; they are more evenly spaced along the chromosomes than would be expected if they were placed randomly. The protein complexes involved in recombination can be visualized as immunofluorescent foci. We have analyzed the distribution of such foci along meiotic prophase chromosomes of the mouse to find out when interference is imposed and whether interference manifests itself at a constant level during meiosis. We observed strong interference among MLH1 foci, which mark CO positions in pachytene. Additionally, we detected substantial interference well before this point, in late zygotene, among MSH4 foci, and similarly, among replication protein A (RPA) foci. MSH4 foci and RPA foci both mark interhomolog recombinational interactions, most of which do not yield COs in the mouse. Furthermore, this zygotene interference did not depend on SYCP1, which is a transverse filament protein of mouse synaptonemal complexes. Interference is thus not specific to COs but may occur in other situations in which the spatial distribution of events has to be controlled. Differences between the distributions of MSH4/RPA foci and MLH1 foci along synaptonemal complexes might suggest that CO interference occurs in two successive steps.
Knot detection in computed tomography images of partially dried jack pine (<i>Pinus banksiana</i>) and white spruce (<i>Picea glauca</i>) logs from a Nelder type plantation (2017)

X-ray computed tomography (CT) of logs means possibilities for optimizing breakdown in sawmills. This depends on accurate detection of knots to assess internal quality. However, as logs are stored, they dry to some extent, and this drying affects the density variation in the log and therefore the X-ray images. For this reason, it is hypothetically difficult to detect log features in partially dried logs using X-ray CT. This paper investigates the effect of improper heartwood–sapwood border detection, possibly due to partial drying, on knot detection in jack pine (Pinus banksiana Lamb.) and white spruce (Picea glauca (Moench) Voss) logs from New Brunswick, Canada. An automatic knot detection algorithm was compared to manual reference knot measurements, and the results showed that knot detection was affected by detected heartwood shape. It was also shown that logs can be sorted into two groups based on how well the heartwood–sapwood border is detected to separate logs with a high knot detection rate from those with a low detection rate. In that way, a decision can be made whether or not to trust the knot models obtained from CT scanning. This can potentially aid both sawmills and researchers working with log models based on CT.
Targeting the Nerve Growth Factor (NGF) Pathway in Drug Discovery. Potential Applications to New Therapies for Chronic Pain (2016)

The neurotrophin nerve growth factor (NGF) has been implicated as a key mediator of chronic pain. NGF binds the tropomysin receptor kinase A (TrkA) and p75, resulting in the activation of downstream signaling pathways that have been linked to pro-nociception. While anti-NGF antibodies have demonstrated analgesia both preclinically and in patients, the mechanism of action of these agents remains unclear. We describe ligands targeting NGF, its receptors, and downstream/related targets. This Perspective highlights large and small molecule approaches to targeting the NGF-TrkA pathway both extra- and intracellularly. In addition, we present a strategic framework for future drug discovery efforts in this pathway beyond the targeting of NGF or its receptors. While existing tools have greatly informed NGF-mediated signaling, ongoing and future pathway research may help focus new drug discovery efforts on key novel targets and mechanisms. This may result in highly differentiated therapeutics with greater efficacy and/or improved safety profiles.
