A Reduced Size CRPA (R-CRPA) for GNSS Receivers (2007)

We have developed a novel reduced size, controlled reception pattern antenna (CRPA) for GNSS receivers with excellent gain characteristics and RCP (right-hand circular polarization) performance for all GNSS frequency bands. The developed CRPA is approximately 4.25” in diameter, and is 0.6” thick. It consists of six antenna elements, each being a tightly wound triangular spiral, shaped like a “pizza’ slice. The six elements are arranged in a circular fashion to create an array that occupies a circular aperture 4.25” in diameter. The spiral has continuous gain of more than 0dB over the entire L frequency band, and can thus cover all navigation satellite bands. Though each individual antenna element within the antenna array does not provide complete upper hemispherical coverage, the desired upper hemispherical coverage can be readily obtained by combining the signals received by the individual elements. The upper hemispherical coverage is obtained by fixed weights without any beam steering. Thus, the reduced size CRPA (R-CRPA) can be used with the current antenna electronics. In this paper, we present the new antenna concept along with measured data to compare the antenna performance with the design data. We also discuss how the antenna can be used to obtain the upper hemispherical coverage, and spatial nulling of the interfering signals using current antenna electronics.
Stabilizing DNA–Protein Co-Crystals via Intra-Crystal Chemical Ligation of the DNA (2021)

Protein and DNA co-crystals are most commonly prepared to reveal structural and functional details of DNA-binding proteins when subjected to X-ray diffraction. However, biomolecular crystals are notoriously unstable in solution conditions other than their native growth solution. To achieve greater application utility beyond structural biology, biomolecular crystals should be made robust against harsh conditions. To overcome this challenge, we optimized chemical DNA ligation within a co-crystal. Co-crystals from two distinct DNA-binding proteins underwent DNA ligation with the carbodiimide crosslinking agent 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) under various optimization conditions: 5′ vs. 3′ terminal phosphate, EDC concentration, EDC incubation time, and repeated EDC dose. This crosslinking and DNA ligation route did not destroy crystal diffraction. In fact, the ligation of DNA across the DNA–DNA junctions was clearly revealed via X-ray diffraction structure determination. Furthermore, crystal macrostructure was fortified. Neither the loss of counterions in pure water, nor incubation in blood serum, nor incubation at low pH (2.0 or 4.5) led to apparent crystal degradation. These findings motivate the use of crosslinked biomolecular co-crystals for purposes beyond structural biology, including biomedical applications.
A Database-Centric Framework for the Modeling, Simulation, and Control of Cyber-Physical Systems in the Factory of the Future (2017)

Abstract The factory of the future scenario asks for new approaches to cope with the incoming challenges and complexity of cyber-physical systems. The role of database management systems is becoming central for control and automation technology in this new industrial scenario. This article proposes database-centric technology and architecture that aims to seamlessly integrate networking, artificial intelligence, and real-time control issues into a unified model of computing. The proposed methodology is also viable for the development of a framework that features simulation and rapid prototyping tools for smart and advanced industrial automation. The full expression of the potentialities in the presented approach is expected in particular for applications where tiny and distributed embedded devices collaborate to a shared computing task of relevant complexity.
Parametric modeling of CVT-based hybrid drive trains (2008)

Abstract — Parametric modeling of CVT-based hybrid drive trains — In this paper the hybridization of a small passenger car equipped with a Continuously Variable Transmission (CVT) is investigated. In this work a parametric optimization procedure is presented in solving the design problem, where the main design objective is fuel consumption. The effects of parameter variation on the fuel consumption have been investigated. Furthermore, a reduced hybrid drive train model is introduced with which the effects of design parameter variation is studied very quickly and with an average error of less than 1.6%.
Design of the Hairpin Ribozyme for Targeting Specific RNA Sequences (2003)

The following steps should be taken when designing the hairpin ribozyme to cleave a specific target sequence: 1. Select a target sequence containing BN*GUC where B is C, G, or U. 2. Select the target sequence in areas least likely to have extensive interfering structure. 3. Design the conventional hairpin ribozyme as shown in Fig. 1, such that it can form a 4 bp helix 2 and helix 1 lengths up to 10 bp. 4. Synthesize this ribozyme from single-stranded DNA templates with a double-stranded T7 promoter. 5. Prepare a series of short substrates capable of forming a range of helix 1 lengths of 5-10 bp. 6. Identify these by direct RNA sequencing. 7. Assay the extent of cleavage of each substrate to identify the optimal length of helix 1. 8. Prepare the hairpin tetraloop ribozyme to determine if catalytic efficiency can be improved.
Eliminating zero-order diffraction in the digital holography wavefront reconstruction with adjustable magnification (2010)

The method of digital holography wavefront reconstruction with adjustable magnification is introduced. Since there is strong zero-order diffraction interference on the reconstruction plane, three different methods are proposed to eliminate zero-order diffraction interference, and compared through experiment. The experimental results demonstrated that the mean subtracted from a hologram is an effective method.

Compact Scene Graphs for Layout Composition and Patch Retrieval (2019)

Structured representations such as scene graphs serve as an efficient and compact representation that can be used for downstream rendering or retrieval tasks. However, existing efforts to generate realistic images from scene graphs perform poorly on scene composition for cluttered or complex scenes. We propose two contributions to improve the scene composition. First, we enhance the scene graph representation with heuristic-based relations, which add minimal storage overhead. Second, we use extreme points representation to supervise the learning of the scene composition network. These methods achieve significantly higher performance over existing work (69.0% vs 51.2% in relation score metric). We additionally demonstrate how scene graphs can be used to retrieve pose-constrained image patches that are semantically similar to the source query. Improving structured scene graph representations for rendering or retrieval is an important step towards realistic image generation.

7. Non-destructive geophysical site investigation—an aid to the redevelopment of sites in urban areas with groundwater problems (1994)

Non-invasive, remote sensing using geophysical methods is reviewed for investigating groundwater-related pollution. Examples are given of how computer-controlled resistivity imaging can be used to define and monitor changes in groundwater composition, and disposition. Geophysical remote sensing of groundwater problems is reviewed and one example of a new application is presented. This new application entails the use of a three-dimensional electrical resistivity technique which can be used for monitoring the spatial extent, and composition of groundwater. Monitoring changes is shown to be a powerful way of identifying the presence of changes in groundwater composition and disposition. Examples are presented that show how realistic three-dimensional modelling can be used to both optimize and interpret the surveys.
Therapeutic DNA Vaccines for Human Papillomavirus and Associated Diseases (2018)

Human papillomavirus (HPV) has long been recognized as the causative agent of cervical cancer. High-risk HPV types 16 and 18 alone are responsible for over 70% of all cases of cervical cancers. More recently, HPV has been identified as an etiological factor for several other forms of cancers, including oropharyngeal, anogenital, and skin. Thus, the association of HPV with these malignancies creates an opportunity to control these HPV lesions and HPV-associated malignancies through immunization. Strategies to prevent or to therapeutically treat HPV infections have been developed and are still pushing innovative boundaries. Currently, commercial prophylactic HPV vaccines are widely available, but they are not able to control established infections or lesions. As a result, there is an urgent need for the development of therapeutic HPV vaccines, to treat existing infections, and to prevent the development of HPV-associated cancers. In particular, DNA vaccination has emerged as a promising form of therapeutic HPV vaccine. DNA vaccines have great potential for the treatment of HPV infections and HPV-associated cancers due to their safety, stability, simplicity of manufacturability, and ability to induce antigen-specific immunity. This review focuses on the current state of therapeutic HPV DNA vaccines, including results from recent and ongoing clinical trials, and outlines different strategies that have been employed to improve their potencies. The continued progress and improvements made in therapeutic HPV DNA vaccine development holds great potential for innovative ways to effectively treat HPV infections and HPV-associated diseases.

Interpretation of Spatial Kinetics for Rod Drop Experiment in Loosely Coupled-Core Systems. (1993)

Abstract Abstract The coupled two-core reactor systems with various degrees of spatial coupling were constructed in the Kyoto University Critical Assembly (KUCA) to study the spatial kinetics observed in the control rod drop experiment. By applying the two-mode and the two-point kinetic models to the space-dependent rod worths measured on the basis of the one-point model, the first-harmonic λ-mode eigenvalue separation and the reactivity coupling coefficient were inferred. The present values of these parameters agreed with the results obtained by the reactor noise measurements and the diffusion calculations. The experimental results show that the magnitudes of the spatial kinetic phenomena including the dependence of the rod reactivity worth on the detector position, the reactivity interaction effect between control rods and the transient flux tilts induced by the rod drop, which have been significantly observed in large thermal and fast power reactors, are inversely proportional to the eigenvalue separation. Applying the two-mode model, the inherent reactivity worths of control rods were also inferred from the space-dependent ones.

Phospholipase C‐δ1 is an essential molecule downstream of Foxnl, the gene responsible for the nude mutation, in normal hair development (2007)

Nude mice exhibit athymia and hairlessness by a loss-of-function mutation in the transcription factor Foxn1 gene. Although the immunological functions of Foxn1 have been studied intensively, there have been relatively few studies of its functions in skin. Foxn1 regulates expression of hair keratins, which is essential for normal hair structure; however, how Foxn1 regulates hair keratin expression and hair formation is largely unknown. In the present study, we found that mice lacking phospholipase C (PLC)-delta1, a key molecule in the phosphoinositide signaling pathway, and nude mice show similar hair abnormalities, such as lack of cuticle and bending. We also found that expression of hair keratins was remarkably decreased in skin of PLC-delta1 knockout mice. Furthermore, expression of PLC-delta1 was induced in Foxn1-transfected U2OS cells. In addition, we showed that PLC-delta1 expression was remarkably decreased in skin of nude mice. In skin and keratinocytes of nude mice as well as PLC-delta1 KO mice, activation of PLC downstream effectors, such as PKC and nuclear factor of activated T cells, was impaired. These results indicate that PLC-delta1 is an essential molecule downstream of Foxn1 in normal hair formation, and strongly suggest that hairlessness in nude mice is caused by insufficient expression of PLC-delta1.
Unsaturated structured soil with multi-porosity = Multi-poröse Strukturen in teilgesättigten Böden (2004)

Soil structure properties are of great importance in a variety of engineering applications.The behavior of such soil is however rather complex and very few results are available to model their hydromechanical properties.Some recent laboratory results are presented in this paper.They concern the hydromechanical response of soil consisting of unsaturated aggregate assemblies.A new oedometer cell for testing unsaturated soil samples under mechanical (external axial load) and hydric stress (matric suction) is used.Stress-strain behavior under various suction levels is discussed.The main results focus on the pore-size distribution of a natural soil with multi-porosity and its variation with total stress and suction.Mercury intrusion porosimetry (MIP) is used here.It is shown how the volume fraction of macropores and micropores decreases, respectively increases, when suction increases.

A stepwise optimization of crystals of rhamnogalacturonan lyase from Aspergillus aculeatus (2002)

Recombinant rhamnogalacturonan lyase from Aspergillus aculeatus has been crystallized by a stepwise procedure and X-ray diffraction data have been collected. The crystals were grown using hanging-drop vapour-diffusion and microseeding techniques. Crystals were obtained showing a flat plate morphology. The crystallization conditions were 20% PEG 4000, 9% PEG 400, 0.1 M (NH(4))(2)SO(4) and 0.1 M sodium acetate pH 4.4. These crystals diffracted to a resolution of 1.5 A. The unit-cell parameters are a = b = 77.0, c = 170.8 A with the possible space group P4(3)2(1)2 or P4(1)2(1)2. There is most likely to be one molecule in the asymmetric unit, leading to a calculated solvent content of approximately 47% for the crystals.

Standardized Outcome Evaluation after Blunt Multiple Injuries by Scoring Systems: A Clinical Follow-Up Investigation 2 Years after Injury (2002)

In a standardized multicenter reexamination of patients with blunt multiple injuries, the general outcome was usually fair or good. Both the complaints and the objective results of specific extremity areas demonstrated that most limitations were because of injuries below the knee. These results were adequately reflected by a comprehensive scoring system, combining self-report and provider report (HASPOC).
Bubble clusters (2007)

Spatial layout is frequently used for managing loosely organized information, such as desktop icons and digital ink. To help users organize this type of information efficiently, we propose an interface for manipulating spatial aggregations of objects. The aggregated objects are automatically recognized as a group, and the group structure is visualized as a two-dimensional bubble surface that surrounds the objects. Users can drag, copy, or delete a group by operating on the bubble. Furthermore, to help pick out individual objects in a dense aggregation, the system spreads the objects to avoid overlapping when requested. This paper describes the design of this interface and its implementation. We tested our technique in icon grouping and ink relocation tasks and observed improvements in user performance.

Differential Signaling Networks Induced by Mild and Lethal Hemorrhagic Fever Virus Infections (2006)

The family Arenaviridae includes several National Institutes of Allergy and Infections Diseases category A select agents which cause hemorrhagic fever. There are few vaccines available, and treatment is limited to ribavirin, which varies in efficacy. Development of new antiviral compounds has been hindered by a lack of understanding of the molecular basis of pathogenesis. We used two variants of Pichinde virus, one attenuated and one virulent in the guinea pig model, to delineate the host determinants which lead to either viral clearance or lethal disease. By analyzing protein level changes using pathway analysis, we have identified key intermediates which may be targets for therapeutic intervention.
