Database Servers on Chip Multiprocessors: Limitations and Opportunities (2007)

Prior research shows that database system performance is dominated by off-chip data stalls, resulting in a concerted effort to bring data into on-chip caches. At the same time, high levels of integration have enabled the advent of chip multiprocessors and increasingly large (and slow) on-chip caches. These two trends pose the imminent technical and research challenge of adapting high-performance data management software to a shifting hardware landscape. In this paper we characterize the performance of a commercial database server running on emerging chip multiprocessor technologies. We find that the major bottleneck of current software is data cache stalls, with L2 hit stalls rising from oblivion to become the dominant execution time component in some cases. We analyze the source of this shift and derive a list of features for future database designs to attain maximum performance.
How deep neural networks can improve emotion recognition on video data (2016)

We consider the task of dimensional emotion recognition on video data using deep learning. While several previous methods have shown the benefits of training temporal neural network models such as recurrent neural networks (RNNs) on hand-crafted features, few works have considered combining convolutional neural networks (CNNs) with RNNs. In this work, we present a system that performs emotion recognition on video data using both CNNs and RNNs, and we also analyze how much each neural network component contributes to the system's overall performance. We present our findings on videos from the Audio/Visual+Emotion Challenge (AV+EC2015). In our experiments, we analyze the effects of several hyperparameters on overall performance while also achieving superior performance to the baseline and other competing methods.
Fault detection and isolation enhancement of an aircraft attitude and heading reference system based on MEMS inertial sensors (2009)

The process of enriching a multisensor avionic strap-down attitude estimation unit with fault detection and isolation (FDI) capabilities is presented. Compact solid-state sensors are integrated in an autonomous emergency guidance system for aircrafts. Optimal attitude estimate is provided by a 9-state extended Kalman filter for fusion of complementary inertial data. Observerbased residual generation can be consequently added with negligible computational overhead. On-line FDI of the different sensors is analyzed and achieved with minimal hardware and software modifications. The proposed detection scheme combines different approaches: physical redundancy (accelerometers), injection of spectrally-decoupled test signals (magnetic sensors) and analytical redundancy (gyros).
Preparation of epitaxial Pb(Zr<i>x</i>Ti1−<i>x</i>)O3 thin films and their crystallographic, pyroelectric, and ferroelectric properties (1989)

Lead zirconate-titanate (PZT) thin films with tetragonal and rhombohedral structures have been successfully grown with good epitaxy on MgO single crystals and on [100]-oriented platinum thin films by rf-magnetron sputtering. The PZT films were obtained by using sputtering targets with compositions of Pb(ZrxTi1−x)O3, where x=0.2–0.8. The tetragonal PZT thin films have a strong [001] orientation, and the rhombohedral ones are (100) oriented. Asymmetric D-E hysteresis loops were observed on the tetragonal films. Nearly symmetric loops were observed on the rhombohedral films and the rhombohedral loops around the morphotropic phase boundary had slim loops. The tetragonal thin films of x=0.45 have a spontaneous polarization of 45 μC/cm2, a remanent polarization of 40 μC/cm2, and a coercive field of 150 kV/cm. It was found that significant pyroelectric currents are detected on both [001]-oriented tetragonal and (100)-oriented rhombohedral PZT films even without a poling treatment, and the direction is the same in all specimens. The relative dielectric constant εr achieves a maximum at the morphotropic phase boundary, as occurs for PZT ceramics. The pyroelectric coefficient γ increases with increase of Zr content and reaches a peak near the phase boundary in the tetragonal thin films. On the other hand, for the rhombohedral films, γ drops around the phase boundary and increases upon increasing Zr content. Thin films of x=0.45 have εr of 400 and γ of 4.2×10−8 (C/cm2 K). These films will be suitable for use in piezoelectric transducers and pyroelectric infrared detectors.
Game Bot Detection via Avatar Trajectory Analysis (2010)

The objective of this work is to automatically detect the use of game bots in online games based on the trajectories of account users. Online gaming has become one of the most popular Internet activities in recent years, but cheating activity, such as the use of game bots, has increased as a consequence. Generally, the gaming community disapproves of the use of bots, as users may obtain unreasonable rewards without making corresponding efforts. However, game bots are hard to detect because they are designed to simulate human game playing behavior and they follow game rules exactly. Existing methods cannot solve the problem as the differences between bot and human trajectories are generally hard to describe. In this paper, we propose a method for detecting game bots based on some dissimilarity measurements between the trajectories of either bots or human users. The measurements are combined with manifold learning and classification techniques for detection; and the approach is generalizable to any game in which avatars' movements are controlled by the players directly. Through real-life data traces, we observe that the trajectories of bots and humans are very different. Since certain human behavior patterns are difficult to mimic, the characteristic can be used as a signature for bot detection. To evaluate the proposed scheme's performance, we conduct a case study of a popular online game called Quake 2. The results show that the scheme can achieve a high detection rate or classification accuracy on a short trace of several hundred seconds.
Glycerolysis of marine oils and the preparation of acetylated monoglycerides (1960)

Conclusions The glycerolysis reaction was applied to menhaden, tuna, herring, sardine, and salmon‐egg oils. Optimum reaction time for the preparation of α‐monoglycerides was found to vary, reproducibly, from 45 to 60 min., depending on the particular kind of marine oil employed. The method was suitable for the preparation of kilogram quantities. A laboratory method for the prepagation of kilogram quantities of highly pure acetylated α‐mono‐glycerides was developed. Both the glycerolysis mixtures from marine oils and their acetylated products were light in color and substantially free of odor. Thin‐layer silicic acid chromatography, as described here, was found suitable for the analysis of acetoglycerides from marine oils. The work indicated that the method may have wide use for the separation and identification of other lipid classes as well.
Second-order statistics of laser-speckle patterns* (1975)

The statistics of laser-speckle patterns in a plane some distance from a coherently illuminated object are considered in more-general terms than previously. The results obtained show that the rms irradiance is equal to the mean. The irradiance spectrum consists of two terms of equal energy. Assuming that the angular size of the object is much less than the surface roughness diffraction angle, we find that the irradiance autocorrelation function separates into a product of object irradiance and surface-roughness terms. The spectrum separates into the sum of low- and high-frequency contributions. Previous calculations are shown to be special cases or consistent with the present analysis.
Dynamic CT measurement of cerebral blood flow: a validation study. (1999)

We have validated a new dynamic CT method for measuring rCBF. The accuracy of this technique suggests that it can be used as an alternative diagnostic tool to assess the cerebral hemodynamics in experimental and clinical situations.
The pheromonal activity of chiral 3‐octanol for <i>Myrmica</i> ants (1985)

ABSTRACT. The (R)‐(‐)‐3‐octanol from the mandibular glands of Myrmica ants is the only enantiomer active as an attractant pheromone for M.scabrinodis Nyl. The S enantiomer is inactive and its presence decreases slightly the response of M.scabrinodis to the R enantiomer. (R) and (S)‐2‐octanol are inactive.
Ylide von Heterocyclen, II: Iodonium‐ und Pyridinium‐Ylide von Malonylheterocyclen (1978)

Abstract Die Reaktion von Malonylheterocyclen wie 4‐Hydroxycumarin ( 1a ) oder ‐carbostyril ( 1b ) mit (Diacetoxyiod)benzolen 2 liefert in guten Ausbeuten die Iodonium‐Ylide 3 . Bei der säurekatalysierten Umsetzung von 3 mit Pyridin oder Isochinolin erhält man die entsprechenden Ylide 4 , während ohne Säurekatalyse eine Umlagerung zu den 4‐Aryloxy‐3‐iod‐Verbindungen 5 eintritt. Diese geben bei reduktiver Entiodierung die 4‐Aryloxy‐Verbindungen 6 . Durch Photocyclisierung bilden 5a und 6a Coumestan ( 8 ). Mit HCl reagiert 3b zum 3‐Chlor‐4‐hydroxy‐carbostyril ( 7 ).
A Photonic Crystal Protein Hydrogel Sensor for <i>Candida albicans</i> (2015)

We report two-dimensional (2D) photonic crystal (PC) sensing materials that selectively detect Candida albicans (C. albicans). These sensors utilize Concanavalin A (Con A) protein hydrogels with a 2D PC embedded on the Con A protein hydrogel surface, that multivalently and selectively bind to mannan on the C. albicans cell surface to form crosslinks. The resulting crosslinks shrink the Con A protein hydrogel, reduce the 2D PC particle spacing, and blue-shift the light diffracted from the PC. The diffraction shifts can be visually monitored, measured with a spectrometer, or determined from the Debye diffraction ring diameter. Our unoptimized hydrogel sensor has a detection limit of around 32 CFU/mL for C. albicans. This sensor distinguishes between C. albicans and those microbes devoid of cell-surface mannan such as the gram-negative bacterium E. coli. This sensor provides a proof-of-concept for utilizing recognition between lectins and microbial cell surface carbohydrates to detect microorganisms in aqueous environments.
Transformation from Requirements to Design for Service Oriented Information Systems. (2005)

Abstract. Service-Oriented Architecture (SOA) and Web services are becoming the universally accepted architectural style for development of modern information systems of enterprises. But the methods of design in SOA are not well established yet. The most of current methodologies are focused on composition of business processes from services. In this work, SOA based design is considered as design of information system where modelling of services and processes composed of services is related to modelling of entities comprising service execution context. It is demonstrated, that various forms of UML 2.0 interactions and state machines fit well for representation of SOA related concepts – services, protocols, choreography, orchestrations, and transactions. The proposed design method consists of two steps – making comprehensive specification of requirements and transforming it to design using State Coordinator pattern that enables loose coupling of stateless services into system operating on the base of information about states of entities. 1
Aberrant intracellular localization of Varicella-Zoster virus regulatory proteins during latency (1998)

Varicella-Zoster virus (VZV) is a herpesvirus that becomes latent in sensory neurons after primary infection (chickenpox) and subsequently may reactivate to cause zoster. The mechanism by which this virus maintains latency, and the factors involved, are poorly understood. Here we demonstrate, by immunohistochemical analysis of ganglia obtained at autopsy from seropositive patients without clinical symptoms of VZV infection that viral regulatory proteins are present in latently infected neurons. These proteins, which localize to the nucleus of cells during lytic infection, predominantly are detected in the cytoplasm of latently infected neurons. The restriction of regulatory proteins from the nucleus of latently infected neurons might interrupt the cascade of virus gene expression that leads to a productive infection. Our findings raise the possibility that VZV has developed a novel mechanism for maintenance of latency that contrasts with the transcriptional repression that is associated with latency of herpes simplex virus, the prototypic alpha herpesvirus.
Argon Inhalation for 24 Hours After Onset of Permanent Focal Cerebral Ischemia in Rats Provides Neuroprotection and Improves Neurologic Outcome (2019)

Neurologic outcome (neuroscore), overall recovery (body weight), and infarct volumes were significantly improved after 24-hour inhalation of 70% argon administered immediately after severe permanent stroke induction. Neurologic outcome and overall recovery were also significantly improved even when argon treatment was delayed for 2 hours or until after reperfusion.
Sensorineural Hearing Loss: Causes and Hearing Rehabilitation (2015)

Sensorineural hearing loss is one of the most common chronic clinical disorders that we can easily encounter. The etiology of sensorineural hearing loss is multifactorial: congenital, idiopathic, traumatic, noise-induced, head injury induced, infectious disease, drug induced, degenerative, immune disorder, vestibular schwannoma and Meniere's disease. Many people are living with the discomfort of hearing loss because fundamental treatment is has not yet been found. Also due to the progress of medical science, human life span has been extended. As the result, the number of patients suffering from hearing loss has increased. But the present situation does not measure up to the demand for recovery of hearing loss. Hearing loss has a great influence on the quality of life. To overcome this situation, neural prostheses such as the cochlear implant and auditory brainstem implant are helpful for the rehabilitation of total deaf patients. Recently, due to the advancement of studies related to hair cell regeneration and the field of gene therapy on the inner ear has made big progress during the last few years. The purpose of this study is to describe the latest known causes and rehabilitation of sensorineural hearing loss.

Look-ahead techniques for micro-opportunistic job shop scheduling (1992)

Scheduling deals with the allocation of resources over time to perform a collection of tasks. Scheduling problems arise in domains as diverse as manufacturing, computer processing, transportation, health care, space exploration, education, etc. Scheduling problems are conveniently formulated as Constraint Satisfaction Problems (CSPs) or Constrained Optimization Problems (COPs). A general paradigm for solving CSPs and COPs relies on the use of backtrack search. Within this paradigm, the scheduling problem is solved through the iterative selection of a subproblem and the tentative assignment of a solution to that subproblem. Because most scheduling problems are NP-complete, even finding a solution that simply satisfies the problem constraints could require exponential time in the worst case. This dissertation demonstrates that the granularity of the subproblems selected by the backtrack search procedure critically affects both the efficiency of the procedure and the quality of the result...
Video Analytics for Surveillance: Theory and Practice [From the Guest Editors (2010)

Video analytics, loosely defined as autonomous understanding of events occurring in a scene monitored by multiple video cameras, has been rapidly evolving in the last two decades. Despite this effort, practical surveillance systems deployed today are not yet capable of autonomous analysis of complex events in the field of view of cameras. This is a serious deficiency as video feeds from millions of surveillance cameras worldwide are not analyzed in real time and thus cannot help with accident, crime or terrorism prevention, and mitigation, issues critical to the contemporary society. Today, these feeds are, at best, recorded to facilitate post-event video forensics.
New ultra high density EPROM and flash EEPROM with NAND structure cell (1987)

In order to realize ultra high density EPROM and Flash EEPROM, a NAND structure cell is proposed. This new structure is able to shrink cell size without scaling of device dimensions. The NAND structure cell realizes a cell as small as 6.43 µm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> using 1.0 µm design rule. As a result, cell area per bit can be reduced by 30% compared with that of a 4M bit EPROM using the conventional structure and the same design rule. It is confirmed that each bit in a NAND cell is able to be programmed selectively. This high performance NAND structure cell is applicable to high density nonvolatile memories as large as 8M bit EPROM and Flash-EEPROM or beyond.
Demand side load management of smart grids using intelligent trading/metering/ billing system (2011)

Conventional power systems have been experiencing transition from centralized supply side management to decentralized supply&demand side management due to power system restructuring and addition of distributed generations (DGs) and Smart Grids (SGs) or Smart Distribution Systems (SDSs) with renewable power sources in the past two decades. Therefore load management under the new operating environment becomes more difficult than that under the conventional environment. This paper presents an Intelligent Metering/Trading/Billing System (ITMBS) and its implementation in Demand Side Load Management (DSLM) of SGs and SDSs. The ITMBS provides real time price information to customers through communication networks. Customers can adjust their demands through setting the operating time of some of the home appliances with energy storage feature such as heaters based on the real time prices to shift their consumptions and save cost. Customers can also participate in Direct Load Control (DLC) program in control center of a micro grid to shift their air condition demands through changing on and off circle based on the real time prices and weather conditions to save energy and to shift system peak load.
Necator americanus Infection in Primates (1971)

Laboratory-bred and feral chimpanzees (Pan troglodytes) and young, laboratory-bred, patas monkeys (Erythrocebus patas) exposed to infective larvae of Necator americanus cultured from human feces developed patent infections in 42 to 54 days; adult, feral patas monkeys were refractory to infec- tion. Patent infections persisted for 16 months in the chimpanzee and for 10 mos. in the monkey with- out any indication of waning. Variation in egg output among animals exposed to the same number of larvae suggested that there was considerable variation in individual susceptibility. It was also evident that large numbers of worms, in some cases, will produce severe anemia in the host.
Distributed Dimension Reduction Algorithms for Widely Dispersed Data. (2002)

It is well known that information retrieval, clustering and visualization can often be improved by reducing the dimensionality of high dimensional data. Classical techniques o#er optimality but are much too slow for extremely large databases. The problem becomes harder yet when data are distributed across geographically dispersed machines. To address this need, an effective distributed dimension reduction algorithm is developed. Motivated by the success of the serial (non-distributed) FastMap heuristic of Faloutsos and Lin, the distributed method presented here is intended to be fast, accurate and reliable. It runs in linear time and requires very little data transmission. A series of experiments is conducted to gauge how the algorithm&apos;s emphasis on minimal data transmission affects solution quality. Stress function measurements indicate that the distributed algorithm is highly competitive with the original FastMap heuristic.
BIST-based delay path testing in FPGA architectures (2002)

The widespread use of field programmable gate arrays (FPGAs) as components in high-performance systems has increased the significance of path delay faults in FPGAs. We present a technique for FPGA path delay fault detection which integrates test insertion with the FPGA placement and routing stages to accomplish testing with low test application time. An accurate static timing analyzer is used to identify critical paths and built-in self-test (BIST) hardware is inserted using a placement and routing tool. Initial experimental results show that testing is accomplished with low test application time for several benchmark designs.
Neutrophil chemoattractant and IL-1-like activity in samples from psoriatic skin lesions. Further characterization. (1988)

The IL-1-like neutrophil chemoattractant activity previously reported by us to be present in the stratum corneum of psoriatic skin lesions has now been characterized further. Aqueous extracts of stratum corneum samples from psoriatic lesions and from the heels of normal volunteers were ultrafiltered to yield 10- to 30-kDa fractions. The ultrafiltered psoriatic preparations consistently contained greater neutrophil chemokinetic activity than the normal heel preparations, but in contrast the latter contained markedly greater IL-1 activity than the former. Successive chromatographic purification of psoriatic lesional stratum corneum extracts showed that the neutrophil chemokinetic material previously reported to co-elute with IL-1 activity on reversed phase HPLC, but to be distinct from C5a des arg, could now be separated by anion exchange HPLC into at least four different chemokinetic compounds that were also resolved from the IL-1 activity. The reversed phase HPLC-purified chemokinetic material from psoriatic stratum corneum was also active in a neutrophil chemotaxis assay. These findings show that samples from psoriatic skin lesions contain a group of novel 10- to 30-kDa neutrophil chemoattractant compounds that are distinct from both C5a des arg and IL-1. The contrasting neutrophil chemokinetic and IL-1 activities in psoriatic lesional and normal heel stratum corneum preparations support the finding that the two activities are produced by different compounds. These neutrophil chemoattractant and IL-1-like compounds may be of pathogenic importance in inflammatory skin disease.
γ-Secretase Inhibitors Enhance Temozolomide Treatment of Human Gliomas by Inhibiting Neurosphere Repopulation and Xenograft Recurrence (2010)

Malignant gliomas are treated with a combination of surgery, radiation, and temozolomide (TMZ), but these therapies ultimately fail due to tumor recurrence. In glioma cultures, TMZ treatment significantly decreases neurosphere formation; however, a small percentage of cells survive and repopulate the culture. A promising target for glioma therapy is the Notch signaling pathway. Notch activity is upregulated in many gliomas and can be suppressed using gamma-secretase inhibitors (GSI). Using a neurosphere recovery assay and xenograft experiments, we analyzed if the addition of GSIs with TMZ treatment could inhibit repopulation and tumor recurrence. We show that TMZ + GSI treatment decreased neurosphere formation and inhibited neurosphere recovery. This enhancement of TMZ treatment occurred through inhibition of the Notch pathway and depended on the sequence of drug administration. In addition, ex vivo TMZ + GSI treatment of glioma xenografts in immunocompromised mice extended tumor latency and survival, and in vivo TMZ + GSI treatment blocked tumor progression in 50% of mice with preexisting tumors. These data show the importance of the Notch pathway in chemoprotection and repopulation of TMZ-treated gliomas. The addition of GSIs to current treatments is a promising approach to decrease brain tumor recurrence.
