Dynamic resource allocation and management in virtual networks and Clouds (2015)

Cloud computing is a promising technology enabling IT resources reservation and utilization on a pay-as-you-go manner. In addition to the traditional computing resources, cloud tenants expect compete networking of their dedicated resources to easily deploy network functions and services. They need to manage an entire Virtual Network (VN) or infrastructure. Thus, Cloud providers should deploy dynamic and adaptive resource provisioning solutions to allocate virtual networks that reflect the time-varying needs of Cloud-hosted applications. Prior work on virtual network resource provisioning only focused on the problem of mapping the virtual nodes and links composing a virtual network request to the substrate network nodes and paths, known as the Virtual network embedding (VNE) problem. Little attention was paid to the resource management of the allocated resources to continuously meet the varying demands of embedded virtual networks and to ensure efficient substrate resource utilization. The aim of this thesis is to enable dynamic and preventive virtual network resources provisioning to deal with demand fluctuation during the virtual network lifetime, and to enhance the substrate resources usage. To reach these goals, the thesis proposes adaptive resource allocation algorithms for evolving virtual network requests. We adress the extension of an embedded virtual node requiring more resources and consider the substrate network profitability. We also deal with the bandwidth demand variation in embedded virtual links. We first provide a heuristic algorithm to deal with virtual nodes demand fluctuation. The work is extended by designing a preventive re-configuration scheme to enhance substrate network profitability. Finally, a distributed, local-view and parallel framework was devised to handle embedded virtual links bandwidth fluctuations. The approach is composed of a controller and three algorithms running in each substrate node in a distributed and parallel manner. The framework is based on the self-stabilization approach, and can manage various forms of bandwidth demand variations simultaneously
Synthesis and Characterization of [NH2C(I)NH2]2ASnI5 with A = Iodoformamidinium or Formamidinium:  The Chemistry of Cyanamide and Tin(II) Iodide in Concentrated Aqueous Hydriodic Acid Solutions (1998)

Crystals of the organic−inorganic compounds [NH2C(I)NH2]2ASnI5 (A = NH2C(I)NH2+ and NH2CHNH2+) have been grown in an inert atmosphere from slowly cooled aqueous hydriodic acid solutions, each with the same starting concentration of dissolved cyanamide and tin(II) iodide. Each compound can be achieved in high purity and yield simply by varying the thermal history of the solution during cooling. If one starts from lower temperatures, cyanamide rapidly undergoes an addition reaction to generate the iodoformamidinium cation, yielding crystals of [NH2C(I)NH2]3SnI5. At higher temperatures, iodoformamidinium is reduced to formamidinium and is ultimately hydrolyzed if heated further or left for long periods of time. When the solution is subjected to an intermediate thermal treatment of 24 h at 80 °C before slow cooling, both cations can be stabilized in the solid-state compound [NH2C(I)NH2]2(NH2CHNH2)SnI5. The [NH2C(I)NH2]3SnI5 structure has recently been reported in the monoclinic space group P21/c and consists of highly distorted SnI6 octahedra which share opposite corners to form extended one-dimensional chains separated by iodoformamidinium cations. The new mixed-cation compound adopts a very similar triclinic (P1) structure, with the lattice parameters a = 6.3635(3) Å, b = 8.8737(5) Å, c = 10.8782(6) Å, α = 111.616(5)°, β = 92.938(4)°, γ = 95.358(4)°, and Z = 1 and with much less distorted SnI6 octahedra and shorter average Sn−I bond lengths. The different local coordination translates into a substantially darker coloration for crystals with A = formamidinium relative to those having A = iodoformamidinium (dark red versus orange). In addition to examining the stability of cyanamide and derivative species in aqueous hydriodic acid solutions, thermal analysis indicates that in an inert atmosphere the iodoformamidinium cation decomposes exothermally in the solid state at approximately 178(2) °C. Ultraviolet illumination studies on the title compounds also demonstrate the photosensitivity of the iodoformamidinium cation within the tin(II) iodide framework.
Prediction and estimation of solvent diffusivities in polyacrylate and polymethacrylates (2003)

Abstract The relationship between polymer side‐chain length and the hole free volume that is effective for solvent diffusion was investigated for polyacrylates and polymethacrylates on the basis of free‐volume theory. Measurements of a polymer's viscoelasticity and solvent diffusivity provided experimental evidence for polymer segment mobility, and the results indicated that hole free volume in a linear polymer increases with hydrocarbon side‐chain length. Because the molecular mechanisms of polymer viscoelasticity and diffusivity are identical, the free‐volume parameters obtained for polyacrylates and polymethacrylates by measuring the polymer viscoelastic‐temperature dependence can reliably be used in predicting the solvent diffusion coefficient. © 2003 Wiley Periodicals, Inc.

Features of Reflection from the Layer of Hyperbolic Metamaterial (2020)

In this paper, we investigate the features of reflection of a plane elliptically polarized electromagnetic wave fallen from isotropic transparent dielectric on a layer of hyperbolic metamaterial with optical axis in an interface and main effective dielectric permittivities less than the permittivity of dielectric. The cases are analyzed when one (ordinary or extraordinary) wave or two waves, exited inside the layer, are inhomogeneous. It is shown that for certain sub-wavelength thickness of the layer one can choose the angles of incidence for which two inhomogeneous (evanescent) waves existing in this layer totally tunnel through it. It is established that, in contrary to ordinary uniaxial crystal, maximal value of reflection coefficient from the metamaterial layer approaches the unity when the thickness increases.
Axial and torsional stability of an improved single‐plane and a new bi‐plane osteotomy technique for supracondylar femur osteotomies (2010)

In replicate femurs, the new bi-plane technique improved axial stability, but in contrast to what was theorized, decreased torsional stability, compared to the single-plane technique. The addition of a bi-cortical screw proximally improved stability under axial loading, but not torsion. Further clinical testing will have to prove if early full weight bearing using the new bi-plane technique is possible.
To what extent has the last two decades seen significant progress in the management of older patients with head and neck cancer? (2021)

Relative survival increased for all head and neck cancer sites in older patients, except for laryngeal cancer. For oropharyngeal, hypopharyngeal and advanced laryngeal cancer, a shift towards non-surgical treatment modalities was observed.
HUMAN WOUND REPAIR (1968)

Connective tissue repair was studied in a series of skin wounds in young adult males. The tissues were examined at 3, 12, and 24 hr, and at 2, 3, 5, 7, 14, and 21 days after wounding. The neutrophilic leukocytes contain within membrane-bounded vacuoles some fibrin and serum protein from the wound; however, most of the granulocytes lyse and release their cytoplasmic contents into the extracellular space. The mononuclear cells undergo a series of morphologic alterations during which they develop a modest amount of relatively poorly developed rough endoplasmic reticulum and an extensive system of smooth-surfaced membranes prior to active phagocytosis. They could be clearly distinguished from immature fibroblasts by the differences in the development of their organelles, particularly the rough endoplasmic reticulum. The perivascular connective tissue adjacent to the wound contains cells which appear like poorly developed or immature fibroblasts. The development of these cells into mature fibroblasts can be followed during the different stages of wound repair. Intimate contact was observed between basal cells of the regenerated epidermis and monocytes in the wound below: cytoplasmic projections of the basal cells extended beneath the basement lamina to the surface of the monocytes. Such contacts were seen only on the 4th-7th day after wounding. Their possible significance is discussed.
The first SEG General Assembly (2008)

The picture on this page says it all: An historic gathering of leaders of many geophysical societies around the globe. The inaugural General Assembly this January in Tulsa was the first such meeting in our history. The idea for this meeting grew out of my first presidential page in the October 2007 issue of The Leading Edge, “Strengthening the ties that bind.” This concept further matured as I traveled worldwide to address different SEG local sections as distinct as DeNver, ColorAdo and HyDerabad, INDIA. I suddenly noticed that—despite major differences in geographic coordinates, language, culture, etc.—there is a common DNA. Everywhere I go, we all speak geophysics, and we all want to advance geophysics and geophysicists.

Enhanced Carbon Dioxide Photoconversion Efficiency by 1D Structured Platinized TiO2 Films (2013)

A facile development of highly efficient platinized titanium dioxide (Pt-TiO 2 ) thin films with unique one dimensional (1D) structure by using versatile gas phase deposition methods was established. The Pt-TiO 2 thin films demonstrated excellent carbon dioxide (CO 2 ) photoreduction efficiency with a maximum quantum efficiency of about 2.41%. Carbon dioxide was selectively converted into methane (CH 4 ), with an optimal CH 4 yield of over 1300 µmol/g-cat/hr, that is due to the synergistic effects of high surface area and minimized charge barriers by highly oriented single phase crystallinity of the TiO 2 thin films, and efficient electron-hole separation by the ultra-small Pt NPs.
CORROSION OF MATERIALS IN FUSED HYDROXIDES (1956)

penformed with 1200-F fused salt, while the dynamic compalibility tests were performed with 1500 deg F fused salts. Potential valve sealing surface materiais were screened from the work both at ORNL. and BMI and tested in valves at ORNL in fused salts at various temperatures from 1000 to l600 deg F. The dynamic compatibility work at ORNL consisted of testing 36 combinations of 10 different materials in fused salt at 1200 deg F. From these tests, the combinations penformed best with regards to resistance to mechanical damage, such as wear, gailing, and seif-welding. (auth)
Thymosin beta 4 regulation of actin in sepsis (2018)

Sepsis results in measurable levels of F-actin in the circulation as well as a decreased concentration of Thymosin Beta 4. It is speculated that F-actinemia contributes to microcirculatory perturbations present in patients with sepsis by disturbing laminar flow. Given that Thymosin Beta 4 inhibits the polymerization of F-actin, it is possible that Thymosin Beta 4 decreases mortality in sepsis via the regulation of actin as well as its other anti-inflammatory properties and should be further pursued as a clinical trial in humans with sepsis.
Titanium‐mediated [CpTiCl2(OEt)] ring‐opening polymerization of lactides: A novel route to well‐defined polylactide‐based complex macromolecular architectures (2010)

Abstract Among three cyclopentadienyl titanium complexes studied, CpTiCl 2 (OEt), containing a 5% excess CpTiCl 3 , has proven to be a very efficient catalyst for the ring‐opening polymerization (ROP) of L ‐lactide (LLA) in toluene at 130 °C. Kinetic studies revealed that the polymerization yield (up to 100%) and the molecular weight increase linearly with time, leading to well‐defined PLLA with narrow molecular weight distributions ( M w / M n ≤ 1.1). Based on the above results, PS‐ b ‐PLLA, PI‐ b ‐PLLA, PEO‐ b ‐PLLA block copolymers, and a PS‐ b ‐PI‐ b ‐PLLA triblock terpolymer were synthesized. The synthetic strategy involved: (a) the preparation of OH‐end‐functionalized homopolymers or diblock copolymers by anionic polymerization, (b) the reaction of the OH‐functionalized polymers with CpTiCl 3 to give the corresponding Ti‐macrocatalyst, and (c) the ROP of LLA to afford the final block copolymers. PMMA‐ g ‐PLLA [PMMA: poly(methyl methacrylate)] was also synthesized by: (a) the reaction of CpTiCl 3 with 2‐hydroxy ethyl methacrylate, HEMA, to give the Ti‐HEMA‐catalyst, (b) the ROP of LLA to afford a PLLA methacrylic‐macromonomer, and (c) the copolymerization (conventional and ATRP) of the macromonomer with MMA to afford the final graft copolymer. Intermediate and final products were characterized by NMR spectroscopy and size exclusion chromatography, equipped with refractive index and two‐angle laser light scattering detectors. © 2010 Wiley Periodicals, Inc.

DeepStreaks: identifying fast-moving objects in the Zwicky Transient Facility data with deep learning (2019)

ABSTRACT We present DeepStreaks, a convolutional-neural-network, deep-learning system designed to efficiently identify streaking fast-moving near-Earth objects that are detected in the data of the Zwicky Transient Facility (ZTF), a wide-field, time-domain survey using a dedicated 47 deg2 camera attached to the Samuel Oschin 48-inch Telescope at the Palomar Observatory in California, United States. The system demonstrates a 96–98 per cent true positive rate, depending on the night, while keeping the false positive rate below 1 per cent. The sensitivity of DeepStreaks is quantified by the performance on the test data sets as well as using known near-Earth objects observed by ZTF. The system is deployed and adapted for usage within the ZTF Solar system framework and has significantly reduced human involvement in the streak identification process, from several hours to typically under 10 min per day.
Two Distinct Forms ofM-Locus Protein Kinase Localize to the Plasma Membrane and Interact Directly withS-Locus Receptor Kinase to Transduce Self-Incompatibility Signaling inBrassica rapa (2007)

Many flowering plants possess systems of self-incompatibility (SI) to prevent inbreeding. In Brassica, SI recognition is controlled by the multiallelic gene complex (S-haplotypes) at the S-locus, which encodes both the male determinant S-locus protein 11 (SP11/SCR) and the female determinant S-receptor kinase (SRK). Upon self-pollination, the S-haplotype-specific interaction between the pollen-borne SP11 and the cognate stigmatic SRK receptor induces SI signaling in the stigmatic papilla cell and results in rejection of the self-pollen. Our genetic analysis of a self-compatible mutant revealed the involvement of a cytoplasmic protein kinase, M-locus protein kinase (MLPK), in the SI signaling, but its exact physiological function remains unknown. In this study, we identified two different MLPK transcripts, MLPKf1 and MLPKf2, which are produced using alternative transcriptional initiation sites and encode two isoforms that differ only at the N termini. While MLPKf1 and MLPKf2 exhibited distinct expression profiles, both were expressed in papilla cells. MLPKf1 localizes to the plasma membrane through its N-terminal myristoylation motif, while MLPKf2 localizes to the plasma membrane through its N-terminal hydrophobic region. Although both MLPKf1 and MLPKf2 could independently complement the mlpk/mlpk mutation, their mutant forms that lack the plasma membrane localization motifs failed to complement the mutation. Furthermore, a bimolecular fluorescence complementation assay revealed direct interactions between SRK and the MLPK isoforms in planta. These results suggest that MLPK isoforms localize to the papilla cell membrane and interact directly with SRK to transduce SI signaling.
Landmine detection using mixture of discrete hidden Markov models (2009)

We propose a landmine detection algorithm that uses a mixture of discrete hidden Markov models. We hypothesize that the data are generated by <i>K</i> models. These different models reflect the fact that mines and clutter objects have different characteristics depending on the mine type, soil and weather conditions, and burial depth. Model identification could be achieved through clustering in the parameters space or in the feature space. However, this approach is inappropriate as it is not trivial to define a meaningful distance metric for model parameters or sequence comparison. Our proposed approach is based on clustering in the log-likelihood space, and has two main steps. First, one HMM is fit to each of the <i>R</i> individual sequence. For each fitted model, we evaluate the log-likelihood of each sequence. This will result in an <i>R</i>&times;<i>R</i> log-likelihood distance matrix that will be partitioned into <i>K</i> groups using a hierarchical clustering algorithm. In the second step, we pool the sequences, according to which cluster they belong, into <i>K</i> groups, and we fit one HMM to each group. The mixture of these <i>K</i> HMMs would be used to build a descriptive model of the data. An artificial neural networks is then used to fuse the output of the <i>K</i> models. Results on large and diverse Ground Penetrating Radar data collections show that the proposed method can identify meaningful and coherent HMM models that describe different properties of the data. Each HMM models a group of alarm signatures that share common attributes such as clutter, mine type, and burial depth. Our initial experiments have also indicated that the proposed mixture model outperform the baseline HMM that uses one model for the mine and one model for the background.
Abstract 69: Cardiac Fibrosis Induced by Mkk6-p38 Activation Alters Myocardial Stiffness and Myofilament Function (2017)

Heart failure with preserved ejection fraction (HFpEF) accounts for at least half of the patients with heart failure, but to date there are no proven therapies for these patients. Cardiac fibrosis and increased collagen content plays an important role in the pathophysiology of HFpEF. Studies in human HFpEF patients have indicated increased cardiac fibrosis, myocardial stiffness and myofilament calcium sensitivity. However, it is unclear how and if cardiac fibrosis directly alters myofilament function. In this study we used a new model of cardiac fibrosis genetically induced by the constitutive activation of MKK6-p38 (MKK6-Tg) signaling specifically in resident cardiac fibroblasts to determine the effect of fibrosis on myofilament stiffness and function. The MKK6-Tg mice develop interstitial and perivascular fibrosis in the heart accompanied with severe diastolic dysfunction, although systolic function remains normal. We measured the passive stiffness and isometric contractile properties of demembranated papillary muscle preparations. Our results show an increase in passive stiffness in demembranated papillary muscles from MKK6-Tg mice compared to NTG littermates when stretched to 24% from sarcomere length of 2.0 μM. Passive tension at SL=2.3 was significantly increased in MKK6-Tg mice (28±4 vs. 13±3 mN/mm 2 , P&lt;0.05) compared to NTG mice, which was ascribed to changes in Titin isoform as well as extracellular matrix composition. The MKK6-Tg mice also show an increase in Ca 2+ sensitivity (pCa 50 =5.72±0.05 vs. 5.56±0.02, P&lt;0.05). This was associated with an increased rate of force redevelopment in MKK6-Tg mice compared to NTG littermates (k TR =35±8 vs. 22±3 s -1 ). Towards understanding the mechanism of these myofilament changes we performed phosphate affinity electrophoresis and saw decreased phosphorylation of both Troponin I and Troponin T in MKK6-Tg hearts. There was no change in troponin I phosphorylation level at Ser23/24, indicating role of none-PKA mediated phosphorylation in mechanical changes seen in this model.
Efficient, Distributed and Interactive Neuroimaging Data Analysis using the LONI Pipeline (2009)

The LONI Pipeline is a graphical environment for construction, validation and execution of advanced neuroimaging data analysis protocols (Rex et al., 2003). It enables automated data format conversion, allows Grid utilization, facilitates data provenance, and provides a significant library of computational tools. There are two main advantages of the LONI Pipeline over other graphical analysis workflow architectures. It is built as a distributed Grid computing environment and permits efficient tool integration, protocol validation and broad resource distribution. To integrate existing data and computational tools within the LONI Pipeline environment, no modification of the resources themselves is required. The LONI Pipeline provides several types of process submissions based on the underlying server hardware infrastructure. Only workflow instructions and references to data, executable scripts and binary instructions are stored within the LONI Pipeline environment. This makes it portable, computationally efficient, distributed and independent of the individual binary processes involved in pipeline data-analysis workflows. We have expanded the LONI Pipeline (V.4.2) to include server-to-server (peer-to-peer) communication and a 3-tier failover infrastructure (Grid hardware, Sun Grid Engine/Distributed Resource Management Application API middleware, and the Pipeline server). Additionally, the LONI Pipeline provides three layers of background-server executions for all users/sites/systems. These new LONI Pipeline features facilitate resource-interoperability, decentralized computing, construction and validation of efficient and robust neuroimaging data-analysis workflows. Using brain imaging data from the Alzheimer's Disease Neuroimaging Initiative (Mueller et al., 2005), we demonstrate integration of disparate resources, graphical construction of complex neuroimaging analysis protocols and distributed parallel computing. The LONI Pipeline, its features, specifications, documentation and usage are available online (http://Pipeline.loni.ucla.edu).
A knowledge discovery object model API for Java (2003)

The Knowledge Discovery Object Model (KDOM) API is particularly useful for medium to large applications, or for a number of smaller software projects with common characteristics or objectives. KDOM can be coupled effectively with other biologically relevant APIs and classes. Source code, libraries, documentation and examples are available at http://www.bcgsc.ca/bioinfo/software.
High-Throughput Screening of the Asymmetric Decarboxylative Alkylation Reaction of Enolate-Stabilized Enol Carbonates (2010)

The use of high-throughput screening allowed for the optimization of reaction conditions for the palladium-catalyzed asymmetric decarboxylative alkylation reaction of enolate-stabilized enol carbonates. Changing to a non-polar reaction solvent and to an electron-deficient PHOX derivative as ligand from our standard reaction conditions improved the enantioselectivity for the alkylation of a ketal-protected,1,3-diketone-derived enol carbonate from 28% ee to 84% ee. Similar improvements in enantioselectivity were seen for a β-keto-ester derived- and an α-phenyl cyclohexanone-derived enol carbonate.
