Left ventricular segmentation from MRI datasets with edge modelling conditional random fields (2013)

The presented model integrates shape and motion information to segment the inner and outer contours in the presence of papillary muscles. On the Sunnybrook dataset we find an average Dice metric of 0.91 ± 0.02 and 0.93 ± 0.02 for the inner and outer segmentations, respectively. Particularly problematic are patients with hypertrophy where the blood pool disappears from view at end-systole.
Funeral in my Head (2010)

Editor’s Note Katie Boyer’s “Funeral in my Head” is an unconventional personal narrative in which the writer imagines her grandmother’s funeral. What do funerals represent to the writer and her family members? What do they represent to you? Close your eyes and recall visiting your grandmother. What sights, sounds, and smells come to mind? What specific details about her grandmother does Boyer include in her essay? How do the imagined details compare to those from her actual experience?
Complete deletion of yeast chromosomal rDNA repeats and integration of a new rDNA repeat: use of rDNA deletion strains for functional analysis of rDNA promoter elements in vivo (2000)

Strains of Saccharomyces cerevisiae were constructed in which chromosomal rDNA repeats are completely deleted and their growth is supported by a plasmid carrying a single rDNA repeat, either a plasmid carrying the 35S rRNA gene transcribed from the native promoter by RNA polymerase I or a plasmid carrying the 35S rRNA gene fused to the GAL7 promoter for transcription by RNA polymerase II. This system has made it possible to assess the expression of rDNA by measuring the ability of synthesized rRNA to support cell growth as well as by measuring the actual rRNA synthesized rather than by the use of reporter mini-rDNA genes. Using this system, deletion analysis of the rDNA promoter confirmed the presence of two elements, the upstream element and the core promoter, and showed that basal transcription from the core promoter, if it takes place in vivo as was observed in vitro, is not sufficient to allow cell growth. We have also succeeded in integration of a rDNA repeat and its copy number expansion at the original chromosomal locus, which will allow future mutational analysis not only of rRNA but also other DNA elements involved in rRNA transcription, rDNA replication and recombination within a repeated rDNA structure.
Sample application by in‐gel rehydration improves the resolution of two‐dimensional electrophoresis with immobilized pH gradients in the first dimension (1994)

We describe a modification in the sample application mode for isoelectric focusing with immobilized pH gradients. Instead of being applied at the surface of the gel in a sample cup, the sample is introduced into the gel during the immobilized pH gradient strip rehydration step. This modification implies the use of low percentage gels (below 3.5% T) and specially designed, but simple, rehydration chambers. The main advantages are a uniform resolution without side effects and the possibility of handling large sample volumes (500 microL for a standard 3 x 160 x 0.5 mm strip), allowing micropreparative work (milligram samples) with a simple experimental design.
Selecting the Team to Meet Passenger Preferences (1989)

Market research is drawn on to examine the hypothesis that passengers′ perceptions of in‐flight service are influenced by cabin crew composition. The conclusions, very generalised, are that customers do have preferences to be served by a cabin crew team that has a high proportion of young female members, some of whom should speak the language(s) relevant to the destination. Some of the passengers in the sample also expressed opinions in favour of the same crew members working together regularly as a team on the assumption that familiarity leads to improved performance. The research was qualitative and cannot be used to draw definite conclusions, but suggestions for further study in the area of team composition are identified with a view to improving customer satisfaction.
The range of medication storage temperatures in aeromedical emergency medical services (1999)

Medications stored aboard an EMS helicopter are exposed to extremes of temperature, even inside a drug bag. Measures are needed to attenuate storage temperature fluctuations aboard aeromedical helicopters.
Development of an Adaptive Force/Position Controller for Robot-Automated Composite Tape-Layering (1993)

The quality of parts produced by a composite tape-laying process is sensitive to the contact force exerted and the abutment of adjacent tape courses kept when the tapes are laid. Thus, a prerequisite for a high performance laying process automated by means of industrial manipulators is the ability to regulate laying force and position precisely in the presence of robot motion inaccuracies and laying contour variations. An on-line adaptive force/position controller for robot-automated laying processes was presented. The contact force error normal to a laying surface is measured by a wrist sensor in real time, while the position error tangent to the surface is measured by sensors found in manipulator joints. Both are modeled as autoregressive (AR) processes, on the basis of which future errors in Cartesian coordinates are forecasted. Via a compliance selection matrix, both predicted errors are fed to joint actuators in a similar manner for taking compensatory actions. In view of the similarity, the force control portion of the scheme was implemented in an experiment using a three degree-of-freedom manipulator and the results indicated a 40 percent average reduction in contact force variations.
Social album: Linking and merging online albums based on social relationship (2012)

Abstract—This work designs a novel prototype system, Social Album, by utilizing social relationship data to link and merge online albums of individuals together. Field study results indicate that “co-event ” albums related to more than one participating individual are the majority of online albums. Two different views are designed based on feedbacks from the interviews: the indexing view provides a metro-map such as an overview of the linked albums, while the browsing view allows individuals to peruse photos without looking at mis-aligned and duplicate photos from merged albums. Hence, through our system, Social Album, to share and gather “co-event ” photos becomes much easier than before, and to browse the photos in the “co-event ” albums also becomes more efficient while still keeping the comprehensiveness of the whole event. Finally, a user study demonstrates the usefulness of the proposed system. I.
Modeling wood gasification in a countercurrent fixed‐bed reactor (2004)

Abstract A one‐dimensional, unsteady mathematical model is presented of fixed‐bed countercurrent wood gasifiers, which couples heat and mass transport with wood drying and devolatilization, char gasification, and combustion of both char and gas‐phase species. The model is used to simulate the structure of the reaction fronts and the gasification behavior of a laboratory‐scale plant as the reactor throughput and the air‐to‐wood (or char) weight ratio are varied. It is observed that a wide zone, acting essentially as a countercurrent heat exchanger, separates combustion/gasification from devolatilization/drying. Moreover, the former zone presents interesting dynamic patterns driven by the highly variable solid/gas heat transfer rates. For a constant air‐to‐wood weight ratio, the gasification process is improved by increasing the reactor throughput as a result of higher temperatures, in spite of the simultaneous reduction in the amount of char generated from wood devolatilization. In fact, an increase in the air‐to‐wood (or char) ratio always lowers the efficiency of the gasification process. Finally, good agreement is obtained between predictions and experiments for the axial temperature profiles and the composition of the producer gas. © 2004 American Institute of Chemical Engineers AIChE J, 50: 2306–2319, 2004
DSP Design and Implementation for the UE Modem Controller of the 3G Long-Term Evolution (2008)

The 3G LTE will provide the increased data rates, improved coverage, improved spectrum efficiency and reduced latency with adapting various transmission parameters for high-speed data transmission. Accordingly, we suggest an efficient method for controlling FPGAs in the user equipment of the 3G LTE. Our proposed DSP software design, the UE Modem Controller, reduces processing latency for controlling modem hardware since it has been designed as interrupt service routines based on its functions and FPGAspsila operation timing. Furthermore, it performs complex computations required in FPGAs and store various physical parameters to control UE modem at the right time.

Basepairing of oligonucleotides to the 3′ end of 16S ribosomal RNA is not stabilized by ribosomal proteins (1984)

We have studied the binding of the octanucleotide (5'-3')d(AAGGAGGT) which is fully complementary to the 3' end of 16S ribosomal RNA, to ribosomes and to the isolated target sequence (5'-3') (ACCUCCUUA). The binding constant for 30S or 70S ribosomes is (5 +/- 2) X 10(7) mol-1, whereas the duplex containing the octa- and the nonanucleotide has an association constant of (6 +/- 3) X 10(7) mol-1. The two values are the same within the experimental error. This result suggests that basepairing at the 3' end of 16S rRNA is not stabilized by ribosomal proteins.
Artifacts and pitfalls in myocardial perfusion imaging. (2006)

Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. However, MPI is a complex process, subject to a variety of artifacts and pitfalls, which may limit its clinical utility. These factors may be related to the patient (including unique aspects of the patient's heart), the nuclear medicine equipment, or the actions of the technologist. After reviewing this article, the reader should be familiar with the causes and the effects of these potential artifacts and pitfalls. The reader should develop an understanding of steps to limit these factors, actions to correct them if they do arise and, when necessary, how to incorporate their influence into the interpretation of the study.
Progress and plans for the U.S. HEP conductor development program (2003)

Although existing accelerators utilize NbTi superconductor, it is likely that any future upgrades or new accelerators will require the use of superconductors with higher critical fields, such as Nb/sub 3/Sn. The High Energy Physics (HEP) program in U.S. Dept. of Energy (DOE) has initiated a conductor development program aimed at developing a high current density, cost-effective conductor for these new applications. The program is industry-based, with a set of target specifications that were derived from the accelerator magnet requirements. Significant progress has been made to date toward the target specifications, and the results will be presented. Plans for further development, in particular the scale-up tasks required to reduce the conductor cost, will be reviewed.
Computer‐aided diagnosis system for the detection of bronchiectasis in chest computed tomography images (2009)

Abstract A computer‐aided diagnosis (CAD) system has been developed for the detection of bronchiectasis from computed tomography (CT) images of chest. A set of CT images of the chest with known diagnosis were collected and these images were first denoised using Wiener filter. The lung tissue was then segmented using optimal thresholding. The Pathology Bearing Regions (PBRs) were then extracted by applying pixel‐based segmentation. For each PBR, a gray level co‐occurrence matrix (GLCM) was constructed. From the GLCM texture features were extracted and feature vectors were constructed. A probabilistic neural network (PNN) was constructed and trained using this set of feature vectors. The images together with the PBRs and the corresponding feature vector and diagnosis were stored in an image database. Rules for diagnosis and for determining the severity of the disease were generated by analyzing the images known to be affected by bronchiectasis. The rules were then validated by a human expert. The validated rules were stored in the Knowledge Base. When a physician gives a CT image to the CAD system, it first transforms the image into a set of feature vectors, one for each PBR in the image. It then performs the diagnosis using two techniques: PNN and mahalanobis distance measure. The final diagnosis and the severity of the disease are determined by correlating the diagnosis determined by both the techniques in consultation with the knowledge base. The system also retrieves similar cases from the database. Thus, this system would aid the physicians in diagnosing bronchiectasis. © 2009 Wiley Periodicals, Inc.

On-Demand Isolation and Manipulation of C. elegans by In Vitro Maskless Photopatterning (2016)

Caenorhabditis elegans (C. elegans) is a model organism for understanding aging and studying animal behavior. Microfluidic assay techniques have brought widespread advances in C. elegans research; however, traditional microfluidic assays such as those based on soft lithography require time-consuming design and fabrication cycles and offer limited flexibility in changing the geometric environment during experimentation. We present a technique for maskless photopatterning of a biocompatible hydrogel on an NGM (Agar) substrate, enabling dynamic manipulation of the C. elegans culture environment in vitro. Maskless photopatterning is performed using a projector-based microscope system largely built from off-the-shelf components. We demonstrate the capabilities of this technique by building micropillar arrays during C. elegans observation, by fabricating free-floating mechanisms that can be actuated by C. elegans motion, by using freehand drawing to isolate individual C. elegans in real time, and by patterning arrays of mazes for isolation and fitness testing of C. elegans populations. In vitro photopatterning enables rapid and flexible design of experiment geometry as well as real-time interaction between the researcher and the assay such as by sequential isolation of individual organisms. Future adoption of image analysis and machine learning techniques could be used to acquire large datasets and automatically adapt the assay geometry.
Decimal multiplier on FPGA using embedded binary multipliers (2008)

Decimal arithmetic has become a major necessity in computer arithmetic operations associated with human-centric applications, like financial and commercial, because the results must match exactly those obtained by human calculations. The relevance of decimal arithmetic has become evident with the revision of the IEEE-754 standard to include decimal floating-point support. There are already a variety of IP cores available for implementing binary arithmetic accelerators in FPGAs. Thus far, however, little work has been done with regard to implementing cores that work with decimal arithmetic. In this paper, we introduce a novel approach to the design of a decimal multiplier in FPGA using the embedded arithmetic blocks and a novel method for binary to BCD conversion. The proposed circuits were implemented in a Xilinx Virtex 4sx35ff877-12 FPGA. The results indicate that the proposed binary to BCD converter is more efficient than the traditional shift and add-3 algorithm and that the proposed decimal multiplier is very competitive when compared to decimal multipliers implemented with direct manipulation of BCD numbers.

The Medicinal Chemistry of Dengue Virus (2016)

The dengue virus and related flaviviruses are an increasing global health threat. In this perspective, we comment on and review medicinal chemistry efforts aimed at the prevention or treatment of dengue infections. We include target-based approaches aimed at viral or host factors and results from phenotypic screenings in cellular assay systems for viral replication. This perspective is limited to the discussion of results that provide explicit chemistry or structure-activity relationship (SAR), or appear to be of particular interest to the medicinal chemist for other reasons. The discovery and development efforts discussed here may at least partially be extrapolated toward other emerging flaviviral infections, such as West Nile virus. Therefore, this perspective, although not aimed at flaviviruses in general, should also be able to provide an overview of the medicinal chemistry of these closely related infectious agents.
Ultrasonography of extremity lymphedema. (1992)

Ultrasonography of the extremities was performed in 91 patients with unilateral or bilateral peripheral lymphedema of the arms or legs. Linear 3.5 to 10 mHz ultrasonographic linear probes were used in accordance with standardized procedure. The data demonstrated a volumetric increase of the lymphedematous limb with increased thickness of both the subcutaneous and subfascial (muscular) compartments consistent with fibrosclerosis in both compartments with chronic disease. Whereas dermal thickening was minimal, subcutaneous and subfascial changes were more prominent in primary than secondary lymphedema. By providing information about the volumetric and structural alterations with chronic lymphedema, ultrasonography safely and simply supplements conventional and isotopic lymphography in assessing patients with chronic lymphedema.
Effect of Adverse Weather Conditions on Vehicle Braking Distance of Highways (2018)

The effect of adverse weather conditions on the safety of vehicles moving on different types of roads and measuring its margin of safety have always been a major research issue of highways. Determining the exact value of friction coefficient between the wheels of the vehicle and the surface of the pavement (usually Asphalt Concrete) in different weather conditions is assumed as a major factor in design process. An appropriate method is analyzing the dynamic motion of the vehicle and its interactions with geometrical elements of road using dynamic simulation of vehicles. In this paper the effect of changes of friction coefficient caused by the weather conditions on the dynamic responses of three types of vehicles: including Sedan, Bus, and Truck based on the results of Adams/car Simulator are investigated. The studies conducted on this issue for different weather conditions suggest values ranging from 0.04 to 1.25. The results obtained from simulation based on Adams/car represent that the friction coefficient in values of 0.9, 0.8, 0.7, 0.6 do not effect on braking distance significantly and it is possible to attribute them all to dry weather condition. However, as it was anticipated the values of 0.5, 0.4, 0.28 and 0.18 have significant differences in braking distance. Hence, the values of 0.5, 0.4, 0.28 and 0.18 can be attributed to wet, rainy, snowy and icy conditions respectively.
Eye movement based evaluation of human-computer interfaces (1998)

This research investigated the feasibility of using eye movement behavior to evaluate computer interface usability. Eleven eye movements measures were used to quantitatively assess interface quality and compared to established usability ratings. Experiments were designed to manipulate interface quality along one of three design concepts: Component Grouping, Representation and Visibility. The interfaces were deliberately designed to provide a range of usability from 'good' to 'poor'. Fifty typical users and thirty industry interface design experts rated interface usability, establishing benchmark assessments for comparison.
The Grouping Experiment presented interface layouts that increasingly mismatch user expectations of component position. Scanpath measures associated with search were significantly (p $<$ 0.05) greater as subject expectations increasingly failed to be met. The Representation Experiment manipulated component representations. Scanpath measures indicative of the extent of information processing significantly (p $<$ 0.05) increase as component representation became inherently less meaningful or distinct. Search related measures also increased as meaningfulness decreased.
The Visibility experiment manipulated the salience of target components relative to other components in the interface. As target component salience increased, search related measures were expected to decrease. However, the majority of the measures were not significantly influenced by component salience (p $>$ 0.05). The lack of effect may have been due to the narrow range of quality differences between the interfaces, suggesting a limit to the sensitivity, not the validity of the scanpath measures.
Factor analysis of the eleven measures resulted in the separation of scanpath measures into three groups: Global Search, Local Search and Processing. A reduced set of six measures was identified as the minimal set that could still quantify the varied spatial and temporal aspects of a scanpath.
Overall, the relative quality assessment based on eye movements corresponded well with the initial usability ratings, providing sufficient evidence for the validity of eye movement characterization as an interface evaluation methodology.
