A semidefinite relaxation approach to mobile cloud offloading with computing access point (2015)

We consider a mobile cloud computing scenario consisting of one user with multiple independent tasks, one computing access point (CAP), and one remote cloud server. The CAP can either process the received tasks from the mobile user or offload them to the cloud, providing additional computation capability over traditional mobile cloud computing systems. We aim to optimize the offloading decision of the user to minimize the overall cost of energy, computation, and delay. It is shown that the problem can be formulated as a non-convex quadratically constrained quadratic program, which is NP-hard in general. We propose an efficient offloading decision algorithm by semidefinite relaxation and a novel randomization mapping method. Our simulation results show that the proposed algorithm gives nearly optimal performance with only a small number of randomization iterations, and adding CAPs to the traditional dichotomy of mobile devices and remote cloud servers can drastically improve mobile cloud computing performance.

Epidermal growth factor receptor-mediated motility in fibroblasts (1998)

Cell motility is induced by many growth factors acting through cognate receptors with intrinsic tyrosine kinase activity (RPTK). However, most of the links between receptor activation and the biophysical processes of cell motility remain undeciphered. We have focused on the mechanisms by which the EGF receptor (EGFR) actuates fibroblast cell motility in an attempt to define this integrated process in one system. Our working model is that divergent, but interconnected pathways lead to the biophysical processes necessary for cell motility: cytoskeleton reorganization, membrane extension, formation of new adhesions to substratum, cell contraction, and release of adhesions at the rear. We postulate that for any given growth factor some of the pathways/processes will be actively signaled and rate-limiting, while others will be permissive due to background low-level activation. Certain couplings have been defined, such as PLCgamma and actin modifying proteins being involved in cytoskeletal reorganization and lamellipod extension and MEK being implicated in detachment from substratum. Others are suggested by complementary investigations in integrin-mediated motility, including rac in membrane protrusion, rho in new adhesions, myosin II motors in contraction, and calpain in detachment, but have yet to be placed in growth factor-induced motility. Our model postulates that many biochemical pathways will be shared between chemokinetic and haptokinetic motility but that select pathways will be activated only during RPTK-enhanced motility.
Betaine-homocysteine Methyltransferase Is a Developmentally Regulated Enzyme Crystallin in Rhesus Monkey Lens (1998)

We describe herein the characterization of a major 45-kDa protein from the soluble betaH-crystallin fraction of rhesus monkey (Macaca mulatta) lens. Based on partial peptide sequence, immunoreactivity, and enzymatic activity, this protein has been identified as betaine-homocysteine S-methyltransferase (BHMT: EC 2.1.1.5), an enzyme that catalyzes the methylation of homocysteine using either betaine or thetins as methyl donors. This protein was found to be expressed abundantly in the nuclear region of the monkey lens, reaching approximately 10% of the total nuclear protein, but was barely detectable in the epithelium and cortex regions of the lens. Because the nucleus represents the early embryonic and fetal stages of lens development, we infer that BHMT expression in the lens of the eye is developmentally regulated. By virtue of its high abundance, BHMT can be considered an enzyme crystallin (psi-crystallin). This is the first enzyme crystallin to be found in primate lenses.
Pedestrian detection with thermopiles using an occupancy grid (2005)

The increase in road safety has been an essential issue for car manufacturers for the past two decades. While present sensor systems mainly focus on the validated detection of conventional crash partners like other vehicles or poles, there is still a lack for a reliable and cost efficient solution for the detection of pedestrians. In this context, a passive infrared system is a viable alternative mainly due to its affordability and environment-friendliness. A pedestrian detection system based on infrared (IR) sensors is presented. The system consists of an array of thermopile sensors which are arranged on the front bumper of the automobile in a way that the region of interest (ROI) is covered by the sensors field of view (FOV). Since thermopiles do not provide distance information, the sensor arrangement should also facilitate object localization. The optimal sensor arrangement is computed through an optimization algorithm. However, for an accurate position estimation, the sensor arrangement should be supported by suitable probabilistic techniques. For this reason, an approach was developed to map the measurements by means of a sensor model to an occupancy grid. The grid contains a probabilistic value in each cell and is ego-motion compensated. The combination of the optimized sensor arrangement and the occupancy grid technique are discussed here and a reliable method for the position estimation of pedestrians is presented.
Occurrence of squalene and dehydrosqualene in streptomycetes (1985)

Squalene, dehydrosqualene and related hydrocarbons were found to constitute an essential part of the neutral lipid fraction extracted from mycelia and membranes of S. hygroscopicus, S. griseus and S. noursei. In comparison with the fraction of the triglycerides, these terpenoid compounds failed to incorporate (U-14C)-acetic acid throughout pulse labelling experiments. This suggested that the pertinent precursors were formed via alternative routes, for instance by catabolising branched-chain amino acids.
The envelope gp120 gene of human immunodeficiency virus type 1 determines the rate of CD4-positive T-cell depletion in SCID mice engrafted with human peripheral blood leukocytes (1996)

We have used envelope recombinant viruses generated between two molecular clones of human immunodeficiency virus type 1 (HIV-1), T-cell-tropic HIV-1SF2 and macrophage-tropic HIV-1SF162, to assess pathogenic potential in the human peripheral blood leukocyte-reconstituted severe combined immune deficiency mouse model. Recombinant HIV-1SF2 viruses expressing the envelope gp120 gene of HIV-ISF162 caused as rapid a CD4+ T-cell depletion as did HIV-1SF162. The reciprocal HIV-1SF162 recombinant virus with the HIV-1SF2 envelope caused slower CD4+ T-cell loss. Although changing the V3 loop sequence of HIV-1SF162 to that of HIV-1SF2 did not change the rate of CD4+ T-cell depletion, replacing the V3 of HIV-1SF2 with the sequence of HIV-1SF162 resulted in virus that was poorly infectious in vivo but not in vitro. These studies suggest that the envelope gene determines properties important for pathogenesis in vivo as well as for cell tropism in vitro. HIV-1 infection in vivo may have more stringent requirements for envelope conformation.
Form errors estimation in free-form 2D and 3D geometries. (2011)

The aim of this work is to present a method for the verification of form tolerances in free-form geometries. Method: New free-form error parameters, in accordance with ISO GPS standards are defined. Geometrical errors in 2D e 3D geometries are calculated using a new fitting method consisting in an association operation where nominal profile/surface is resized (with an offset), located and oriented on the non-ideal geometry. Form tolerance is estimated using peak-to-valley deviation after the best fit. Result: Automatic algorithms are implemented to analyse 2D free-form profiles of moulds for ophthalmic lenses obtained with grinding and polishing operations and to analyse 3D free-form surfaces of an injection moulded lamp lens for automotive industry. Discussion & Conclusion: The comparison between results obtained using this approach and using traditional fitting methods shows differences on the fitting and errors parameters estimation. In particular in the traditional fitting there is a repartition of the size error contribution in the translation and form errors. The differences increase proportionally to the offset value estimated. The calculation of offset parameter allows the separation of size from geometric errors in free-form profiles/surfaces and the “true” form error estimation.
Specificity and mechanism of in vitro adherence of Candida albicans. (1985)

Adherence of 14C-glucose labeled Candida albicans to vaginal epithelial cells was measured in the presence of 10 potential inhibitory sugars at concentrations of 5 to 150 mg per ml for 90 minutes at 37 degrees C. In competitive inhibition experiments, no inhibition of adherence was seen with any sugar at any concentration. On the contrary, with the exception of the aminosugars glucosamine, galactosamine, and mannosamine, increased attachment of Candida to vaginal epithelial cells was found in the presence of dextrose, galactose, mannose, alpha-methyl-mannoside, N-acetyl-glucosamine, N-acetyl-galactosamine, and N-acetyl-mannosamine. Increased adherence was not associated with recognizable changes in the electron microscopic appearance of Candida cell surface or alterations in fungal cell hydrophobicity as measured by interaction chromatography. Measurement of nonreceptor-specific adherence of Candida to glass beads revealed similar increased attachment in the presence of the test sugars, suggesting that adherence of Candida may not require specific yeast adhesin-cell receptor interaction.
Automated Landing Site Evaluation for Semi-Autonomous Unmanned Aerial Vehicles (2008)

A system is described for identifying obstacle-free landing sites for a vertical-takeoff-and-landing (VTOL) semi-autonomous unmanned aerial vehicle (UAV) from point cloud data obtained from a stereo vision system. The relatively inexpensive, commercially available Bumblebee stereo vision camera was selected for this study. A "point cloud viewer" computer program was written to analyze point cloud data obtained from 2D images transmitted from the UAV to a remote ground station. The program divides the point cloud data into segments, identifies the best-fit plane through the data for each segment, and performs an independent analysis on each segment to assess the feasibility of landing in that area. The program also rapidly presents the stereo vision information and analysis to the remote mission supervisor who can make quick, reliable decisions about where to safely land the UAV. The features of the program and the methods used to identify suitable landing sites are presented in this thesis. Also presented are the results of a user study that compares the abilities of humans and computer-supported point cloud analysis in certain aspects of landing site assessment. The study demonstrates that the computer-supported evaluation of potential landing sites provides an immense benefit to the UAV supervisor.
Real-time teleconsultation with high-resolution and large-volume medical images for collaborative healthcare (2000)

Real-time consultation between referring physicians or radiologists with an expert is critical for timely and adequate management of problem cases. During consultation, both sides need to: 1) synchronously manipulate high-resolution digital radiographic images or large volume MR/CT images; 2) perform interpretation interactively; and 3) converse with audio. We present a specifically designed teleconsultation system in a digital imaging and communication in medicine picture archiving and communication systems clinical environment. The system uses bidirectional remote control technology to meet critical teleconsultation application requirements with high-resolution and large-volume medical images operated in a limited-bandwidth network setting. We give the system design and implementation methods, and also describe the teleconsultation procedure and protocol used in this system. Finally, laboratory and clinical evaluation results are discussed.
Long-term Recordings of Local Field Potentials From Implanted Deep Brain Stimulation Electrodes (2012)

Postoperative LFP activity can be recorded years after DBS implantation and demonstrates a similar profile in response to movement as during acute recordings, although amplitude may decrease. These results support the feasibility of constructing a closed-loop, patient-responsive DBS device based on LFP activity.
Aspirin-Triggered Lipoxin A4 and B4 Analogs Block Extracellular Signal-Regulated Kinase-Dependent TNF-α Secretion from Human T Cells (2003)

Lipoxins (LX) and their aspirin-triggered 15-epimer endogenous isoforms are endogenous anti-inflammatory and pro-resolution eicosanoids. In this study, we examined the impact of LX and aspirin-triggered LXA(4)-stable analogs (ATLa) on human T cell functions. 15-epi-16-(p-fluoro)phenoxy-LXA(4) (ATLa(1)) blocked the secretion of TNF-alpha from human PBMC after stimulation by anti-CD3 Abs, with the IC(50) value of approximately 0.05 nM. A similar action was also exerted by the native aspirin-triggered 15-epi-LXA(4), a new 15-epi-16-(p-trifluoro)phenoxy-LXA(4) analog (ATLa(2)), as well as LXB(4), and its analog 5-(R/S)-methyl-LXB(4). The LXA(4) receptor (ALX) is expressed in peripheral blood T cells and mediates the inhibition of TNF-alpha secretion from activated T cells by ATLa(1). This action was accomplished by inhibition of the anti-CD3-induced activation of extracellular signal-regulated kinase, which is essential for TNF-alpha secretion from anti-CD3-activated T cells. These results demonstrate novel roles for LX and aspirin-triggered LX in the regulation of T cell-mediated responses relevant in inflammation and its resolution. Moreover, they provide potential counterregulatory signals in communication(s) between the innate and acquired immune systems.
Studies on the furan series. Part VII. A preparation of 2,3‐Di(2‐furyl and thienyl)furans (1977)

Abstract Furoin reacts smoothly with dimethyl acetylenedicarboxylate via a Michael addition, which is followed by a dihydrofuran ring formation. After elimination of water the previously unknown 2,3‐di(2‐furyl)furan structure is produced. Thenoin gives a side reaction to yield a fumaric acid derivative in addition to the expected 2,3‐di(2‐thienyl)furan. A mechanism for the side reaction is suggested. The reactivities of the prepared new furan structures towards some oxidation, hydrogenation and electrophilic reagents were determined.
Properties of Freestanding GaN Prepared by HVPE Using a Sapphire as Substrate (1998)

In this work, the freestanding GaN single crystalline substrates without cracks were grown by hydride vapor phase epitaxy (HVPE) and its some properties were investigated. The GaN substrate, having a current maximum size of 350 -thickness and 100 area, were obtained by HVPE growth of thick film GaN on sapphire substrate and subsequent mechanical removal of the sapphire substrate. A lattice constant of = 5.18486 and a FWHM of DCXRD was 650 arcsec for the single crystalline GaN substrate. The low temperature PL spectrum consist of three excitonic emission and a deep D- A pair recombination at 1.8eV. The Raman E, (high) mode frequency was 567 which was the same as that of strain free bulk single crystals. The Hall mobility and carrier concentration was 283$cm^3$/ V.sand 1.1, respectively.
STUDY ON FRICTION BETWEEN ROOFING MATERIALS AND SNOW ON ROOF (1988)

The former paper (part1) presented the results of experiments made on the static friction between the ice block and staple roofing materials.In this paper the experimental results of the sliding velocity and kinetic friction which were occurred in the friction angle are presented. Sliding expriments were carried out by the apparatus adapted the method of "slant table" which was used in the former study. The sliding mass, roofing materials, and other conditions of this experiments are same as the study part 1 at all.The summary of the results is shown below.(1) The changes of the sliding velocity and kinetic friction in the case of the sliding slant under about 20% is different with the changes of them in the case of the sliding slant over about 20%.(2) In the case of a slant under some 20%, the mean velocity depend on the roughness of materials' surface or the condition of temperature. A ratio of the kinetic friction to the static friction is roughly 80% in this slant condition.(3) In the case of a slant over some 20%, change of the mean velocity depend on the gravity acceleration and the value of kinetic friction decrease suddenly with increases of the sliding slant.
Abstract 131: Differential Regulation of Pitx2 Expression in Pulmonary Vein Muscle Sleeves and Left Atrium with Aging: Implication for Pulmonary Vein Triggers (2012)

Introduction: Pitx2, Paired-like homeodomain transcription factor 2, is a homeobox transcription factor that regulates left-right asymmetry during cardiogenesis. Pitx2 insufficiency in the left atrium (LA) has been linked to LA remodeling and arrhythmogenesis in age-related atrial fibrillation (AF). However, the main triggers for AF reside in pulmonary vein muscle sleeves (PVs). Whether Pitx2 insufficiency in PVs also plays a pathogenic role in generating trigger foci remains to be determined. Also, changes in Pitx2 expression in PVs with age remain unclear. We use qRT-PCR and Illumina microarrays to determine age-related changes in Pitx2 expression of PVs in wild type (WT) & heterozygous Pitx2cnull+/- mice, and in humans with or without AF. Methods: PV and LA regions were obtained from 1-23 month-old WT and Pitx2cnull+/- mice. Human PVs were obtained from ~110D human fetal hearts (E110D aborted fetus), two groups of adult donor hearts [20-30s year-old (yo) and 40-50 yo] and two patients with persistent AF. These tissues were used for genetic expression analysis. Results: Pitx2c expression decreases slightly with age in mouse LA and PV tissues. The expression levels of Pitx2c of Pitx2cnull+/- mice in LA are consistently at 55.2±10.5% of WT but at near-equal levels in PVs over four different age groups. In contrast, during human development, Pitx2 expression in PV muscle sleeves first decreases from ~E110D to ~30 yo but increases from 30 to 50 yo. In patients with AF, Pitx2 expression in PVs is only lower by 15% while HCN4 expression is higher by 13.5% when compared to control PVs at >50 yo. Expressions of type 2 Ryanodine receptors and calsequestrin in human PVs increase with age but decrease by ~30% with AF, suggesting impaired calcium handling abilities may play more significant roles than Pitx2 in the generation of PV triggers of AF. Conclusions: Genetic analysis of Pitx2c expression in PV muscle sleeves and LA tissues of WT and Pitx2cnull+/- mice revealed differential expression patterns. In human PVs, Pitx2 expression shows a regulation pattern with age distinct from that in mice, and genes linked to intracellular calcium handling may play a more important role than Pitx2 in generating trigger foci in PVs to initiate AF.

Four-mirror anastigmats, part 1: a complete solution set for all-spherical telescopic systems (2007)

The concept of the simplest possible reflecting anastigmat is discussed, and anastigmats consisting of four spherical mirrors are introduced in this context as being the last remaining family for which the solution set has not been thoroughly explored. Burch's “plate diagram” method is introduced and used to derive a closed-form analytical solution for four-spherical-mirror anastigmatic telescope systems. This solution is then applied to mapping the solution space for four-spherical-mirror anastigmats. Two novel systems are revealed that represent the first published instances of axially symmetrical, all-spherical anastigmatic reflecting telescope designs with concave primary mirrors. Due to the completeness of the analytic description of the solution set, it also can be stated that there are no other design variants for this class of system.

Microbial regulation of intestinal radiosensitivity (2005)

We describe a method for treating germ-free (GF) mice with gamma-irradiation and transplanting them with normal or genetically manipulated bone marrow while maintaining their GF status. This approach revealed that GF mice are markedly resistant to lethal radiation enteritis. Furthermore, administering lethal doses of total body irradiation to GF mice produces markedly fewer apoptotic endothelial cells and lymphocytes in the mesenchymal cores of their small intestinal villi, compared with conventionally raised animals that have acquired a microbiota from birth. Analysis of GF and conventionally raised Rag1-/- mice disclosed that mature lymphocytes are not required for the development of lethal radiation enteritis or the microbiota-associated enhancement of endothelial radiosensitivity. Studies of gnotobiotic knockout mice that lack fasting-induced adipose factor (Fiaf), a fibrinogen/angiopoietin-like protein normally secreted from the small intestinal villus epithelium and suppressed by the microbiota, showed that Fiaf deficiency results in loss of resistance of villus endothelial and lymphocyte populations to radiation-induced apoptosis. Together, these findings provide insights about the cellular and molecular targets involved in microbial regulation of intestinal radiosensitivity.
On the design of a DEA-based device to pot entially assist lower leg disorders: an analytical and FEM investigation accounting for nonlinearities of the leg and device deformations (2015)

Comparison with non-linear FEM simulations show that the analytical models used in this work can closely estimate interaction between an active compression bandage and a human calf. In addition, compliancy of the leg should not be neglected when either designing a compression band or predicting the compressive force it can exert. The methodology proposed in this work can be extended to other types of elastic compression bandages and garments for biomedical applications.
