Ferroelectric single crystal materials in optoelectronics and microwave photonic applications (2005)

Recent interests in developing miniature wavelength-converted fiber lasers, couplers, and modulators, and integration of these with optical fibers and in microwave transmission systems, demand for example high-quality defect-free single-crystal fibers of materials with high electro-optic coefficients, high optical damage resistance, tailored core-cladding structures, and domain configurations, depending on specific applications. An overview is given on the materials development utilizing the floating zone crystal growth facilities at Penn State including the laser heated pedestal growth (LHPG) technique and the optic image furnace, with focus on applications utilizing ferroelectric single crystal materials. Materials development, particularly the ferroelectric oxygen octahedral structural families (perovskites and tungsten bronzes) are emphasized. The exploration for those crystal fibers in applications that require field and frequency agile, high electro-optic and nonlinear optic properties, and tailored physical and photonic properties in desired wavelength range, are presented in this paper.

VISUAL PERFORMANCE AND OPTICAL PROPERTIES OF FRESNEL MEMBRANE PRISMS: PART 1 - DISTORTION* (1971)

The Fresnel prism, an outgrowth of the early nineteenth century lenses designed for lighthouses by Augustin J. Fresnel, can be imagined as a series of small prisms lying adjacent to each other on a thin transparent platform. Ophthalmic quality Fresnel prisms of almost any power have recently been made of flexible material (less than 1 mm thick) which can be pressed onto existing prescription lenses. A comparison of membrane Fresnel and conventional prisms is made in terms of design variables available for each in optimizing prism performance.
Tryptophan catabolism in Pseudomonas aeruginosa and potential for inter-kingdom relationship (2016)

Pa produces and secretes several metabolites of the kynurenine pathway. Here, we demonstrate the existence of new metabolic pathways leading to synthesis of bioactive molecules, kynurenic acid and 3-OH-kynurenine in Pa. The kynurenine pathway in Pa is critical to produce anthranilate, a crucial precursor of some Pa virulence factors. Metabolites (anthranilate, kynurenine, kynurenic acid) are produced at sustained levels both ex vivo and in vivo leading to a possible immunomodulatory interplay between bacteria and host. These data may imply that pulmonary infection with bacteria highly expressing the kynurenine pathway enzymes could influence the equilibrium of the host's tryptophan metabolic pathway, known to be involved in the immune response to infection. Further studies are needed to explore the effects of these metabolic changes on the pathophysiology of Pa infection.
TableTops: Worthwhile Experiences of Collocated and Remote Collaboration (2007)

Tabletops incite people to collaborate around shared documents. We propose DIGITABLE, a platform for collocated and remote collaboration which attempts to preserve the fluidity of interactions and the mutual awareness of copresence. DIGITABLE combines a multiuser tactile tabletop, a video-communication system and a robust computer vision module for distant users' gesture visualization. From an experiment, we show that DIGITABLE improves the efficiency of a collaborative task in remote configuration. We also show that remote gesture visualization facilitates coordination as it provides to local participants important information such as intentionality and pointing. Thus, collocated and remote configurations are both worthwhile experiences: remote collaboration is not seen anymore as a poor ersatz of collocated collaboration, although presence feeling is not uniformly perceived by participants.
Synergistic activation by collagen and 15-hydroxy-9 alpha,11 alpha-peroxidoprosta-5,13-dienoic acid (PGH2) of phosphatidylinositol metabolism and arachidonic acid release in human platelets. (1982)

Collagen stimulates the activation of phosphatidylinositol (PI)-specific phospholipase C (EC 3.1.4.10) in human platelets, as manifested by the disappearance of PI, the transient formation of diacylglycerol (DG), and release of myoinositol. Platelets exposed to collagen also form lysophosphatidylinositol (LPI). Maximum formation of DG occurs within 60 s of the addition of collagen and is in proportion to the concentration of collagen provided, up to 100 micrograms/2 x 10(9) platelets/ml. Hydrolysis of PI, formation of DG, and release of arachidonic acid are all inhibited approximately 68% by aspirin or indomethacin, both of which inhibit platelet cyclooxygenase. This inhibition is reversed by the product of cyclooxygenase activity, 15-hydroxy - 9 alpha,11 alpha - peroxidoprosta - 5,13 - dienoic acid (PGH2), or by the PGH2 analogue and agonist, U-46619. The counteracting effects of either PGH2 or the PGH2 analogue can be blocked, in turn, by a PGH2 antagonist, U-51605. Neither PGH2 nor its stable analogue is, by itself, an efficient stimulus for PI breakdown to DG and LPI in platelets. However, in conjunction with collagen, these agents synergistically promote the net breakdown of PI and the release of arachidonic acid in aspirin-treated platelets. Our findings thereby imply that PGH2 has an important role in regulating both the release of its precursor, arachidonic acid, and the metabolism of PI induced by collagen. Dibutyryl cyclic AMP or prostaglandin D2 (PGD2), a prostaglandin that elevates concentrations of cAMP in platelets by stimulating adenylate cyclase, inhibits the hydrolysis of PI induced by collagen by 70%. The activation of PI metabolism by collagen appears to be inhibited by cAMP independently of any effects of this inhibitor on the formation of PGH2.
The Oligomeric State of 46‐kDa Mannose 6‐Phosphate Receptor does not Change Upon Intracellular Recycling and Binding of Ligands (1996)

46-kDa mannose-6-phosphate receptor forms homooligomers in cell membranes and in detergent solution. The quaternary structure of detergent-solubilized 46-kDa mannose 6-phosphate receptor is regulated by the presence of ligands, pH and receptor concentration [Waheed, A. & von Figura, K. (1990) Eur. J. Biochem. 193, 47-54). To find out whether the intracellular recycling of 46-kDa mannose 6-phosphate receptor is accompanied by changes in its quaternary structure, we have performed chemical cross-linking in membranes of intact cells. In all conditions tested, the dimer was the predominating form (more than 67% of total 46-kDa mannose 6-phosphate receptor). The amount of trimeric and tetrameric forms varied among cell lines and contributed up to 20% of total endogenous 46-kDa mannose 6-phosphate receptor in human and mouse fibroblasts. Within a given cell line, the ratio of the oligomers was not significantly changed upon elevating endosomal pH by bafilomycin A1, upon changes in receptor occupancy (treatment of cells with tunicamycin or use of mouse fibroblasts deficient in 300-kDa mannose 6-phosphate receptor), nor upon depletion of adaptors from clathrin-coated vesicles of the trans Golgi network by brefeldin A. At the cell surface, where 46-kDa mannose 6-phosphate receptor does not bind ligands, the percentage of dimer was similar to that observed intracellularly. Thus, the oligomeric state of 46-kDa mannose 6-phosphate receptor apparently does not change during recycling as well as binding and dissociation of ligands. In view of the abundance of the dimer of 46-kDa mannose 6-phosphate receptor in situ, our data suggest that it represents the main physiologically active form of the receptor, and therefore present indirect evidence that binding of ligands to 46-kDa mannose 6-phosphate receptor is probably regulated by conformational changes of receptor or ligand rather than by changes in the quaternary structure.
Scene layout in text-to-scene conversion (2014)

The text-to-scene conversion is such a process that converts the input text into 3D scenes automatically based on the natural language processing. The scene layout is the basic research content and the key section of the text-to-scene conversion. It realizes the automatic layout through identifying the information about scene layout from the input text and relying on a large database of 3D models. In this paper, the method which can extract the information about scene layout from text descriptions has been put forward by using language rules. And on this basis we proposed a method of layout reasoning by combining entity recognition and spatial analysis. The experiments show that the methods can obtain expected results.
Free-form deformation of solid geometric models (1986)

A technique is presented for deforming solid geometric models in a free-form manner. The technique can be used with any solid modeling system, such as CSG or B-rep. It can deform surface primitives of any type or degree: planes, quadrics, parametric surface patches, or implicitly defined surfaces, for example. The deformation can be applied either globally or locally. Local deformations can be imposed with any desired degree of derivative continuity. It is also possible to deform a solid model in such a way that its volume is preserved.The scheme is based on trivariate Bernstein polynomials, and provides the designer with an intuitive appreciation for its effects.
Congestion control for M2M traffic with heterogeneous throughput demands (2013)

Machine-to-machine (M2M) communications are bringing new challenges to congestion control in the Internet of Things. One key issue is to facilitate the proper functioning of a wide range of M2M applications with drastically different throughput demands. Traditional Internet congestion control algorithms aim at sharing bandwidth among traffic flows equally, limiting their suitability for M2M communications. To maintain comparable levels of QoS of heterogeneous M2M applications when congestion is present, we propose a distributed congestion control algorithm which allocates transmission rates to M2M flows in proportion to their demands, through the use of a simple technique which we call “proportional additive increase”. To ease M2M application development, we make a further attempt to stabilize the throughputs of M2M flows controlled by the algorithm. We present simulation results to illustrate the effectiveness of the algorithm in achieving the desired rate allocation, as well as the challenge we face in stabilizing throughputs.
Multihypothesis prediction using decoder side-motion vector derivation in inter-frame video coding (2008)

In this paper, a multihypothesis prediction scheme for inter frame video coding is proposed. Using a template matching algorithm, motion vectors are derived at the decoder side instead of explicitly coding the motion vectors into the bitstream. Therefore, higher numbers of hypotheses can be used in the averaging process at no additional coding cost. The proposed scheme has been implemented into the H.264/AVC reference software. Simulation results show bitrate reductions compared to H.264/AVC of 7.7% on average for the tested video sequences. It is shown that part of the performance gain is due to rounding effects in H.264/AVC sub-pixel interpolation which can be exploited in the averaging calculation of the proposed multihypothesis prediction. Experiments with an improved interpolation filter for both reference scheme and the proposed scheme still yield bitrate reductions of 4.7% on average.

Women have a higher LVEF than men in the general population, secondary to a higher stroke volume for a given EDV independent of known potential confounders.
Discrete Start Sites for DNA Synthesis in the YeastARS1Origin (1998)

Sites of DNA synthesis initiation have been detected at the nucleotide level in a yeast origin of bidirectional replication with the use of replication initiation point mapping. The ARS1 origin of Saccharomyces cerevisiae showed a transition from discontinuous to continuous DNA synthesis in an 18-base pair region (nucleotides 828 to 845) from within element B1 toward B2, adjacent to the binding site for the origin recognition complex, the putative initiator protein.

The event was focussed around the performance of a jazz rhapsody entitled Psychedelia written by saxophonist Graeme Lyall. It also featured a lightshow and film by artist and sculptor Gordon Mutch.
SSL: Smart Street Lamp Based on Fog Computing for Smarter Cities (2018)

Both safety and energy conservation are very important advantages of smart cities. Namely, the city street lamp is correlated with both safety and energy conservation. Therefore, a street lamp is an indispensable part of the smart cities. However, current street lamps have lack of smart characteristics, which increases both danger and energy consumption. In order to address these problems, a smart street lamp (SSL) based on the fog computing for smarter cities is proposed in this paper. The advantages of the proposed SSL are as follows: 1) fine management, because every street lamp can be operated independently; 2) dynamic brightness adjustment, all street lamps can be adjusted dynamically; and 3) autonomous alarm on abnormal states, each street lamp can report the abnormal status independently, such as broken, stolen, and so on. The experimental results showed that the proposed SSL can improve the energy efficiency and reduce danger.
Follow‐up of late‐onset Pompe disease patients with muscle magnetic resonance imaging reveals increase in fat replacement in skeletal muscles (2020)

Our study identifies that skeletal muscle fat fraction continues to increase in patients with LOPD despite the treatment with enzymatic replacement therapy. These results suggest that the process of muscle degeneration is not stopped by the treatment and could impact muscle function over the years. Hereby, we show that fat fraction along with muscle function tests can be considered a good outcome measures for clinical trials in LOPD patients.
Development and field testing of the FootFall planning system for the ATHLETE robots (2012)

Abstract The FootFall Planning System is a ground‐based planning and decision support system designed to facilitate the control of walking activities for the ATHLETE (All‐Terrain Hex‐Limbed Extra‐Terrestrial Explorer) family of robots. ATHLETE was developed at NASA's Jet Propulsion Laboratory and is a large, six‐legged robot designed to serve multiple roles during manned and unmanned missions to the moon; its roles include transportation, construction, and exploration. Over the 4 years from 2006 through 2010 the FootFall Planning System was developed and adapted to two generations of the ATHLETE robots and tested at two analog field sites [the Human Robotic Systems Project's Integrated Field Test at Moses Lake, Washington, June 2008, and the Desert Research and Technology Studies (D‐RATS), held at Black Point Lava Flow in Arizona, September 2010]. Having 42 degrees of kinematic freedom, standing to a maximum height of just over 4 m, and having a payload capacity of 450 kg in Earth gravity, the current version of the ATHLETE robot is a uniquely complex system. A central challenge to this work was the compliance of the high‐degree‐of‐freedom robot, especially the compliance of the wheels, which affected many aspects of statically stable walking. This paper reviews the history of the development of the FootFall system, sharing design decisions, field test experiences, and the lessons learned concerning compliance and self‐awareness. © 2012 Wiley Periodicals, Inc.

A computer assisted orthopaedic surgical system for distal locking of intramedullary nails (1997)

This paper presents a prototype system for computer assisted surgery, the purpose of which is to assist orthopaedic surgeons when performing distal locking of intramedullary nails. This system comprises three components, namely: an Intelligent Image Intensifier, a Trajectory Tactician and an Intelligent Trajectory Guide. The Intelligent Image Intensifier is an X-ray vision system that provides accurate X-ray images. Such images enable the Trajectory Tactician software to analyse the operation site and calculate the trajectory required for a screw to lock an intramedullary nail. This involves the capture of two X-ray images from which are extracted the projections of the nail's edge boundaries and its distal locking holes. Using an analytical mathematical model of the nail, the position and orientation of the nail is determined. The trajectory is then implemented by the surgeon using the Intelligent Trajectory Guide. Evaluation in the laboratory suggests that the system is capable of reliably inserting a locking screw into an intramedullary nail. The rapidity with which this computer assisted method achieves locking should benefit both patient and surgeon by reducing radiation dosage and the length of time required to lock a nail.

Phase grating generation and optical phase conjugation in photorefractive polymer/dissolved liquid crystal composites (2004)

The orientational photorefractive properties of photorefractive mesogenic composites have been investigated by means of two-beam coupling and degenerate four-wave mixing. Photorefractive mesogenic composites, consisting of low molar mass liquid crystals, polymer, and photoconductive sensitizer, constitute novel organic materials possessing high performance photoreractivity. The refractive index change was estimated on the basis of the theory of two-beam coupling and four-wave mixing, and large index modulation of over 0.01 was obtained.
