Moving portraits (2014)

We present an approach for generating face animations from large image collections of the same person. Such collections, which we call photobios, are remarkable in that they summarize a person's life in photos; the photos sample the appearance of a person over changes in age, pose, facial expression, hairstyle, and other variations. Yet, browsing and exploring photobios is infeasible due to their large volume. By optimizing the quantity and order in which photos are displayed and cross dissolving between them, we can render smooth transitions between face pose (e.g., from frowning to smiling), and create moving portraits from collections of still photos. Used in this context, the cross dissolve produces a very strong motion effect; a key contribution of the paper is to explain this effect and analyze its operating range. We demonstrate results on a variety of datasets including time-lapse photography, personal photo collections, and images of celebrities downloaded from the Internet. Our approach is completely automatic and has been widely deployed as the "Face Movies" feature in Google's Picasa.
Visible Harmonic Generation in CMOS-Compatible Integrated Photonic Devices (2010)

We observe continuous-wave second- and third-harmonic generation in silicon nitride ring resonators pumped in the C-band. The enhancement of the ring allows pump powers as low as 3 mW to generate detectable outputs.
40-Gb/s return-to-zero alternate-mark-inversion (RZ-AMI) transmission over 2000 km (2003)

We report on the transmission of 40-Gb/s alternate-mark-inversion return-to-zero (RZ-AMI) signals over more than 2000 km (20 /spl times/ 100 km) of nonzero dispersion fiber at a bit-error ratio of 10/sup -9/. The RZ-AMI signal is generated using a single, nonreturn-to-zero-driven modulator in combination with an optical delay interferometer. This transmitter allowed for a 40-Gb/s record receiver sensitivity of 78 photons/bit.
Articular cartilage and biomechanical properties of the long bones in Frzb‐knockout mice (2007)

The genetic association between osteoarthritis and FRZB polymorphisms is corroborated by increased cartilage proteoglycan loss in 3 different models of arthritis in Frzb(-/-) mice. Loss of Frzb may contribute to cartilage damage by increasing the expression and activity of MMPs, in a WNT-dependent and WNT-independent manner. FRZB deficiency also resulted in thicker cortical bone, with increased stiffness and higher cortical appositional bone formation after loading. This may contribute to the development of osteoarthritis by producing increased strain on the articular cartilage during normal locomotion but may protect against osteoporotic fractures.
TIGHTENING PROCEDURES FOR LARGE-DIAMETER ANCHOR BOLTS (1997)

Recent failures of cantilever overhead sign structures in Michigan and elsewhere, coupled with the absence of standards for tightening methods for the double-nut system used with large-diameter anchor bolts in similar structures in Texas have been the motivation for this study. Practices of various field offices were reviewed, a literature study was performed, and both laboratory studies and field studies were performed. Three questions were raised: How tight do the anchor bolt nuts need to be? What techniques and procedures are best suited for tightening? How can tightness best be inspected? Standards for tightening procedures for large-diameter anchor bolts are proposed. In current Texas Department of Transportation practice, the contractor is left to his or her own judgment concerning how tight to tighten the nuts on the double-nut anchor bolt system. Recent bolt failures in other states have raised concerns about nut tightening procedures. When the nuts of a double-nut system are not tightened sufficiently, fatigue loading, and even impact loading, can be factors in the performance of the bolts. Three full-size test specimens were built in the laboratory to evaluate tightening methods and the fatigue performance of the double-nut system used for anchorage of cantilever overhead sign structures (COSS) and on high mast illumination poles (HMIP). Analytical and numerical studies were performed to identify and study parameters affecting the stresses in the anchor bolts. Field studies were conducted to measure the wind-load induced anchor bolt reactions and stresses in one specimen of each type. This report details these studies and the findings.
Systematic study on work-function-shift in metal/Hf-based high-k gate stacks (2009)

Change in the work function (WF) of the gate electrode material caused by the contact with Hf-based high-k gate dielectrics was investigated by means of the flat-band voltage (Vfb) shift in capacitance-voltage curves, and the interface dipole, which modifies the WF, was characterized by x-ray photoelectron spectroscopy. We observed a negative Vfb shift and corresponding interface dipole, which suggest the formation of oxygen vacancy (VO) in the Hf-based oxides. In contrast, we observed an opposite (positive) Vfb shift and interface dipole when Au electrodes were formed on cleaned Hf-based dielectrics. This indicates that Au–Hf bond hybridization at the Au/HfSiON interface also causes effective WF modulation, as theoretically predicted by Shiraishi et al. (Tech. - Dig. Int. Electron Devices Meet. 2005, 43).
3D-printed Bioresorbable Scaffold for Periodontal Repair (2015)

laser sintering, periodontal ligament. Tissue-engineered constructs have potential to induce bone-ligament complex regeneration to treat disease- or trauma-induced damage to periodontia (Ivanovski et al. 2014). Herein, we provide the first reported human case of treatment of a large periodontal osseous defect with a 3D-printed bioresorbable patient-specific polymer scaffold and signaling growth factor. The treated site remained intact for 12 mo following therapy. This report suggests that 3D-printed image-based scaffolds offer potential for periodontal reconstruction. Limitations gleaned from this case and opportunities for treatment of other bony defects are discussed.
High Density and Performance Multiplication for FPGA (2018)

Arithmetic based applications are one of the most common use cases for modern FPGAs. Currently, machine learning is emerging as the fastest growth area for FPG As, renewing an interest in low precision multiplication. There is now a new focus on multiplication in the soft fabric - very high-density systems, consisting of many thousands of operations, are the current norm. In this paper we introduce multiplier regularization, which restructures common multiplier algorithms into smaller, and more efficient architectures. The multiplier structure is parameterizable, and results are given for a continuous range of input sizes, although the algorithm is most efficient for small input precisions. The multiplier is particularly effective for typical machine learning inferencing uses, and the presented cores can be used for dot products required for these applications. Although the examples presented here are optimized for Intel Stratix 10 devices, the concept of regularized arithmetic structures are applicable to generic FPGA LUT architectures. Results are compared to Intel Megafunction IP as well as contrasted with normalized representations of recently published results for Xilinx devices. We report a 10% to 35% smaller area, and a more significant latency reduction, in the range of 25% to 50%, for typical inferencing use cases.
Exciton management in organic photovoltaic multi-donor energy cascades (2023)

Disclosed herein are organic photosensitive optoelectronic devices, such as organic photovoltaics, including a photoactive region, wherein the photoactive region contains an energy-cascading multilayer donor region. The energy-cascading multilayer donor region may drive exciton transfer from an anode to a dissociating interface while reducing exciton quenching, improving overlap with the solar spectrum, and minimizing polaron pair recombination, resulting in improved device performance.
Ligand‐Enabled β‐Methylene C(sp3)−H Arylation of Masked Aliphatic Alcohols (2020)

Abstract Despite recent advances, reactivity and site‐selectivity remain significant obstacles for the practical application of C(sp 3 )−H bond functionalization methods. Here, we describe a system that combines a salicylic‐aldehyde‐derived L,X‐type directing group with an electron‐deficient 2‐pyridone ligand to enable the β‐methylene C(sp 3 )−H arylation of aliphatic alcohols, which has not been possible previously. Notably, this protocol is compatible with heterocycles embedded in both alcohol substrates and aryl coupling partners. A site‐ and stereo‐specific annulation of dihydrocholesterol and the synthesis of a key intermediate of englitazone illustrate the practicality of this method.
SHOCK-LESS HIGH RATE COMPACTION OF POROUS BRITTLE MATERIALS (2009)

The dynamic behavior of granular materials such as granular silica (sand), technical ceramics, and porous geological substances has importance to a variety of engineering applications. Although the mechanical behaviors of sand and other granular ceramics have been studied extensively for several decades, the dynamic behavior of such materials remains poorly understood. This paper describes how instrumented electromagnetic tube compression driven by capacitive discharge can be used to measure compaction of porous materials at high and controlled strain rates. The technique relies on electromagnetically crushing a powder‐filled conductive tube. By measuring the current as a function of time and the tube displacement through Photon Doppler Velocimetry (PDV) sufficient data can be obtained to reveal the behavior of the porous material. The method will be described in detail and example data will be shown for compaction of silica sand.
Augmenting Neutralization breadth against Diverse HIV-1 by increasing the Ab-Ag interface on V2 (2021)

SUMMARY Understanding maturation pathways of broadly neutralizing antibodies (bnAbs) against HIV-1 in non-human primates can be highly informative for HIV-1 vaccine development. We now obtained a lineage of J038 from Chinese rhesus macaques after 7-years of SHIV infection. J038 has short complementary determining loops and neutralizes 54% of global circulating HIV-1 strains. Its binding induces a unique “up” conformation for one of the V2 loops in the trimeric envelope glycoprotein (Env) and is heavily dependent on glycan, which provides nearly half of the binding surface. The unmutated common ancestor of the J038 lineage antibodies binds monomeric gp120 and neutralizes the autologous virus. Continuous maturation enhances neutralization potency and breadth of J038 lineage antibodies via expanding antibody-Env contact areas surrounding the core region contacted by germline-encoded residues. Developmental details and recognition features of J038 lineage antibodies revealed here provide a new pathway for maturation elicitation of V2-targeting bnAbs. Highlights • Long-term infected NHPs develop antibodies neutralizing up to 54% of HIV-1 strains • Antibody J038 binds one V2 loop on HIV-1 Env trimer in a unique “up” position • UCA of the J038 lineage effectively neutralizes the autologous virus • J038 lineage antibodies mature through gradually increased contact to glycans

Suppression of Mesoscopic Order by Complementary Interactions in Supramolecular Polymers (2012)

We show here that complementary interactions can suppress mesoscopic order and thus lead to a counterintuitive change in material properties. We present results for telechelic supramolecular polymers based on poly(propylene oxide) (PPO), thymine (Thy), and diaminotriazine (DAT). The self-complementary systems based on Thy exhibit lamellar order and 2D crystallization of Thy in the bulk. We show that the microphase segregation is inhibited by addition of DAT: the strong complementary Thy-DAT interaction inhibits crystallization of thymine in microdomains and lamellar structuration. As a result, the supramolecular polymer with only weakly self-complementary stickers is a solid, whereas the supramolecular polymer with strongly complementary stickers is a liquid.
Applications of Ni(II)/Cr(II)-mediated coupling reactions to natural products syntheses (1992)

Abstract
Preferential Repair of the Transcribed DNA Strand in Plants (2012)

UV-induced pyrimidine dimers block the progression of both DNA and RNA polymerases. In order to reduce the disruptive effect of these lesions on gene expression, bacteria, yeasts, and animals preferentially repair the transcribed strand of actively expressed genes, essentially employing the stalled polymerase as a detector for bulky lesions. It has been assumed, but not demonstrated, that this prioritization of repair also occurs in plants. Here we demonstrate that in the constitutively expressed gene encoding the RNA polymerase II large subunit cyclobutane pyrimidine dimers are removed from the transcribed strand more rapidly than from the non-transcribed strand.
Effective desynchronization by means of double-pulse phase resetting (2001)

A double-pulse stimulation technique is presented here for the first time which makes it possible to effectively desynchronize a synchronized cluster of globally coupled phase oscillators in the presence of noise. The first, stronger pulse of the double pulse restarts the cluster independently of its initial dynamic state. The second, weaker pulse desynchronizes the cluster by hitting it in a vulnerable state. After the desynchronization the cluster tends to resynchronize since the incoherent state is unstable. Nevertheless, repeated administration of double pulses blocks the cluster's resynchronization. This approach can directly be applied to real data. Accordingly, a demand-controlled deep-brain double-pulse stimulation technique is suggested for the therapy of patients suffering from Parkinson's disease or essential tremor.
New Mechanistic Insights into Reductions of Halides and Radicals with Samarium(II) Iodide (1992)

This account summarizes the current mechanistic understanding of the reductions of halides and radicals with samarium(II) iodide. Special emphasis is placed on the samarium Barbier reaction (reductive coupling of a halide and a ketone with samarium(II) iodide). Previous evidence that has been interpreted in support of ketyl-radical coupling mechanisms or in support of free anions is critically evaluated in the light of new mechanistic evidence. It is suggested that bimolecular samarium Barbier reactions often proceed by an organometallic addition mechanism with three key steps: (a) the halide is reduced by samarium(II) iodide to form a free radical, (b) the radical is reduced by samarium(II) iodide to form an alkyl samarium reagent, and (c) the alkylsamarium reagent adds to the carbonyl group. Past results are re-evaluated in this new mechanistic light, and new synthetic possibilities are suggested for both radical and organometallic reactions. 1. Introduction 2. Kagan's Mechanisms 3.

Electrochemical System for Simultaneous Monitoring of Immobilized Algal Flagellar Movement and Phototaxis (2008)

An electrochemical system equipped with dual electrodes was developed for the simultaneous monitoring of motility and phototaxis of immobilized single flagellate alga, Volvox carteri. The flagellate alga was immobilized on a polyion complex membrane. Photoinduced behavior of flagellate alga was recorded as changes in the redox currents for a coexisting redox marker ([Fe(CN)6]3−). From the amperometric measurements, the immobilized alga possessed its flagellar activity on the polyion complex membrane. In addition, it was found that changes of algal flagellar movement induced by phototaxis gave rise to different current changes at each electrode.
Search for bottom squark pair production in proton–proton collisions at $$\sqrt{s}=13$$ s = 13 TeV with the ATLAS detector (2016)

The result of a search for pair production of the supersymmetric partner of the Standard Model bottom quark ([Formula: see text]) is reported. The search uses 3.2 fb[Formula: see text] of <i>pp</i> collisions at [Formula: see text] TeV collected by the ATLAS experiment at the Large Hadron Collider in 2015. Bottom squarks are searched for in events containing large missing transverse momentum and exactly two jets identified as originating from <i>b</i>-quarks. No excess above the expected Standard Model background yield is observed. Exclusion limits at 95 % confidence level on the mass of the bottom squark are derived in phenomenological supersymmetric <i>R</i>-parity-conserving models in which the [Formula: see text] is the lightest squark and is assumed to decay exclusively via [Formula: see text], where [Formula: see text] is the lightest neutralino. The limits significantly extend previous results; bottom squark masses up to 800 (840) GeV are excluded for the [Formula: see text] mass below 360 (100) GeV whilst differences in mass above 100 GeV between the [Formula: see text] and the [Formula: see text] are excluded up to a [Formula: see text] mass of 500 GeV.

Signaling function of PRC2 is essential for TCR-driven T cell responses (2018)

Differentiation and activation of T cells require the activity of numerous histone lysine methyltransferases (HMT) that control the transcriptional T cell output. One of the most potent regulators of T cell differentiation is the HMT Ezh2. Ezh2 is a key enzymatic component of polycomb repressive complex 2 (PRC2), which silences gene expression by histone H3 di/tri-methylation at lysine 27. Surprisingly, in many cell types, including T cells, Ezh2 is localized in both the nucleus and the cytosol. Here we show the presence of a nuclear-like PRC2 complex in T cell cytosol and demonstrate a role of cytosolic PRC2 in T cell antigen receptor (TCR)-mediated signaling. We show that short-term suppression of PRC2 precludes TCR-driven T cell activation in vitro. We also demonstrate that pharmacological inhibition of PRC2 in vivo greatly attenuates the severe T cell-driven autoimmunity caused by regulatory T cell depletion. Our data reveal cytoplasmic PRC2 is one of the most potent regulators of T cell activation and point toward the therapeutic potential of PRC2 inhibitors for the treatment of T cell-driven autoimmune diseases.
A new strategy to screen molecular imaging probe uptake in cell culture without radiolabeling using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. (2005)

These results demonstrate that MALDI-TOF-MS is a powerful analytic tool for rapid screening and characterization of phosphonium cations as molecular probes. This technique can potentially be applied to the evaluation of other imaging probes or drugs and thus may facilitate their rational design and development.
Using execution trace data to improve distributed systems (2003)

Understanding the dynamic behavior of a system is a key determinant to successful system maintenance. This paper contributes two studies at Ericsson Radio Systems of the perfective maintenance of large and distributed systems. Our approach is a holistic method based on tracing and the technical solution to acquisition of trace data is to use CORBA interceptors. Our method has proven useful in solving a wide variety of problems in design as well as implementation and test-all this at a small price. Examples of improvements are performance, new test cases and merging of objects.
Thermal Characterization of Electrically Injected Thin-Film InGaAsP Microdisk Lasers on Si (2007)

We have performed a numerical and experimental analysis of the thermal behavior of electrically injected microdisk lasers that are defined in an InGaAsP-based thin film bonded on top of a silicon wafer. Both the turn-on as well as the pulsed-regime temperature evolution in the lasing region was simulated using the finite-element method. The simulation results are in good agreement with experimental data, which was extracted from the broadening of the time-averaged emission spectra. Lasing at room temperature was only possible in pulsed regime due to the high thermal resistance (10 K/mW). Some strategies to decrease the thermal resistance of the microdisk lasers are proposed and discussed.
Gas-2-Pipe™, A Concept for Treating Gas to Rich Gas Quality in a Subsea or Unmanned Facility (2016)

Abstract Field developments on the Norwegian Continental Shelf (NCS) have become cost intensive both for greenfield and for tieback / brownfield developments. A large existing infrastructure with future free capacity is available consisting of processing platforms and transport systems. The objective for the Gas-2-Pipe™ concept is to reduce capex/opex intensive topside modifications and topside weight and space constraints by utilizing the established infrastructure and host facilities in a flexible way. The process concept treats a gas dominated well stream in order to meet the so called rich gas transport specifications. Rich gas specifications in the Norwegian transport system are mainly related to a cricondenbar specification in the range of 105 to 110 bar and to a water dew point specification of typically -18 °C at 70 bar. Gas is treated in two steps where hydrocarbon dew point is obtained by sea water cooling and pressure reduction to form a gas and a liquid phase. Water content in the separated gas is reduced by injecting lean glycol through a compact mixer unit and separating out the rich glycol from the gas in a separation unit. Gas is also cooled by sea water in the dehydration process. A single- or two-stage dehydration process may be used. Considerations regarding process design, process parameter selection and glycol distribution rate are given. After treatment, the gas is compressed to the necessary export pressure and injected directly into the pipeline. Processing takes place in a subsea or topside unmanned environment where necessary utilities are imported from one or several hosts. Required utilities are typically power- and control system and glycol for gas dehydration. Produced liquid hydrocarbons and water is routed to a host for further stabilization and treating. The concept may become an enabler when nearby host capacity is gas constrained and traditional tie-back is too cost intensive. The concept is seen as an enabler for field development of gas dominated fields with a potential for cost reduction compared to conventional concepts. The main gaps are identified and a qualification strategy for the key technology elements is given, ranging from small scale and pilot scale testing to implementation of new technology elements in traditional field developments.
