High-power picosecond pulse delivery through hollow core photonic band gap fibers (2016)

We demonstrated robust and bend insensitive fiber delivery of high power laser with diffraction limited beam quality for two different kinds of hollow core band gap fibers. The light source for this experiment consists of ytterbium-doped double clad fiber aeroGAIN-ROD-PM85 in a high power amplifier setup. It provided 22ps pulses with a maximum average power of 95W, 40MHz repetition rate at 1032nm (~2.4&mu;J pulse energy), with M<sup>2</sup> &lt;1.3. We determined the facet damage threshold for a 7-cells hollow core photonic bandgap fiber and showed up to 59W average power output for a 5 meters fiber. The damage threshold for a 19-cell hollow core photonic bandgap fiber exceeded the maximum power provided by the light source and up to 76W average output power was demonstrated for a 1m fiber. In both cases, no special attention was needed to mitigate bend sensitivity. The fibers were coiled on 8 centimeters radius spools and even lower bending radii were present. In addition, stimulated rotational Raman scattering arising from nitrogen molecules was measured through a 42m long 19 cell hollow core fiber.

Impact of technology scaling on energy aware execution cache-based microarchitectures (2004)

Reducing total power consumption in high performance microprocessors can be achieved by limiting the amount of logic involved in decoding, scheduling and executing each instruction. One of the solutions to this problem involves the use of a microarchitecture based on an Execution Cache (EC) whose role is to cache already done work for later reuse.In this paper, we explore the design space for such a microarchitecture, looking at how the cache size, associativity and replacement algorithm affect the overall performance and power efficiency. We also look at the scalability of this solution across next process generations, evaluating the energy efficiency of such caching mechanisms in the presence of increasing leakage power. Over a spectrum of SPEC2000 benchmarks, an average of 35% energy reduction is achieved for technologies ranging from 130nm to 90nm and 65nm, at the expense of a negligible performance hit.
Application of cyclic fluorocarbon/argon discharges to device patterning (2015)

With increasing demands on device patterning to achieve smaller critical dimensions and pitches for the 5 nm node and beyond, the need for atomic layer etching (ALE) is steadily increasing. In this work, a cyclic fluorocarbon/Ar plasma is successfully used for ALE patterning in a manufacturing scale reactor. Self-limited etching of silicon oxide is observed. The impact of various process parameters on the etch performance is established. The substrate temperature has been shown to play an especially significant role, with lower temperatures leading to higher selectivity and lower etch rates, but worse pattern fidelity. The cyclic ALE approach established with this work is shown to have great potential for small scale device patterning, showing self-limited etching, improved uniformity and resist mask performance.
Effect of phonon confinement on the thermal conductivity of In0.53Ga0.47As nanofilms (2018)

Over the past few decades, significant progress has been made to manipulate thermal transport in solids. Most of the effort has focused on reducing the phonon mean free path through boundary scattering. Herein, we demonstrate that the phonon confinement effect can also be used as a tool for managing thermal transport in solids. We measured the thermal conductivities of 10–70-nm-thick In0.53Ga0.47As nanofilms and found that the thermal conductivities decrease as the film thickness decreases. However, the reasons for this reduction differ for films with different thicknesses. The thermal conductivity of the 30- and 70-nm-thick In0.53Ga0.47As nanofilms decreases because of severe phonon boundary scattering. Our analysis indicates that phonon confinement occurs in the 10- and 20-nm-thick In0.53Ga0.47As nanofilms, which modifies phonon dispersion leading to changes in the phonon group velocity and the Debye temperature. These experimental and theoretical results could help to elucidate the phonon confinement effect in nanomaterials as well as establish a platform for understanding nanoscale thermal physics.
Attack of the Genes: Finding Keys and Parameters of Locked Analog ICs Using Genetic Algorithm (2020)

Hardware intellectual property (IP) theft is a major issue in today's globalized supply chain. To address it, numerous logic locking and obfuscation techniques have been proposed. While locking initially focused on digital integrated circuits (ICs), there have been recent attempts to extend it to analog ICs, which are easier to reverse engineer and to copy than digital ICs. In this paper, we use algorithms based on evolutionary strategies to investigate the security of analog obfuscation/locking techniques. We present a genetic algorithm (GA) approach which is capable of completely breaking a locked analog circuit by finding either its obfuscation key or its obfuscated parameters. We implement both the GA attack as well as a more naïve satisfiability modulo theory (SMT)-based attack on common analog benchmark circuits obfuscated by combinational locking and parameter biasing. We find that GA attack can unlock all the circuits using only the locked netlist and an unlocked chip in minutes. On the other hand, while the SMT attack converges faster, it requires circuit specification to execute and it also returns multiple keys that need to be brute-forced by a post-processing step. We also discuss how the GA attack can generalize to other recent analog locking techniques not tested in the paper.
Millimeter-wave laser modulation using III-V semiconductor travelling wave electro-optic Mach-Zehnder interferometer structures (1998)

It is expected that Wavelength Division Multiplex (WDM) fiber optic communications will be providing the high-speed backbone for the networks of the future. At the transmitter end, external laser modulation remains the approach of choice when high quality performance with reduced chirp is required at extra-high frequencies. Semiconductor based external laser modulators have the advantage of potential integration with the laser on the same substrate. On chip integration resolves the polarization sensitivity problem of the modulator, but is technologically more difficult to implement, often requiring material re-growth or ion-implantation [1] to ensure the transparency of the optical waveguides.

Robust dexterous manipulation under object dynamics uncertainties (2017)

Dexterous manipulation has broad applications in assembly lines, warehouses and agriculture. To perform broad-scale manipulation tasks, it is desired that a multi-fingered robotic hand can robustly manipulate objects without knowing the exact objects dynamics (i.e. mass and inertia) in advance. However, realizing robust manipulation is challenging due to the complex contact dynamics, the nonlinearities of the system, and the potential sliding during manipulation. In this paper, a dual-stage grasp controller is proposed to handle these challenges. In the first stage, feedback linearization is utilized to linearize the nonlinear uncertain system. Considering the structures of uncertainties, a robust controller is designed for such a linearized system to obtain the desired Cartesian force on the object. In the second stage, a manipulation controller regulates the contact force based on the Cartesian force from the first stage. The dual-stage grasp controller is able to realize robust manipulation without contact modeling, prevent the slippage, and withstand 40% mass and 50% inertia uncertainties. Moreover, it does not require velocity measurement or 3D/6D tactile sensor. Simulation results on Mujoco verify the efficacy of the proposed method. The simulation video is available at [1].
Mechanistic Study of a Ru-Xantphos Catalyst for Tandem Alcohol Dehydrogenation and Reductive Aryl-Ether Cleavage (2013)

We employ density functional theory (DFT) calculations and kinetics measurements to understand the mechanism of a xantphos-containing molecular ruthenium catalyst acting on an alkyl aryl ether linkage similar to that found in lignin to produce acetophenone and phenol. The most favorable reaction pathway suggested from DFT is compared to kinetics measurements, and good agreement is found between the predicted and the measured activation barriers. The DFT calculations reveal several interesting features, including an unusual 5-membered transition state structure for oxidative insertion in contrast to the typically proposed 3-membered transition state, a preference for an O-bound over a C-bound Ru–enolate, and a significant kinetic preference for the order of product release from the catalyst. The experimental measurements confirm that the reaction proceeds via a free ketone intermediate, but also suggest that the conversion of the intermediate ketone to acetophenone and phenol does not necessarily require ketone dissociation from the catalyst. Overall, this work elucidates the kinetically and thermodynamically preferred reaction pathways for tandem alcohol dehydrogenation and reductive ether bond cleavage by the ruthenium-xantphos catalyst.
Channel Gain Cartography for Cognitive Radios Leveraging Low Rank and Sparsity (2017)

Channel gain cartography aims at inferring the channel gains between two arbitrary points in space based on the measurements (samples) of the gains collected by a set of radios deployed in the area. Channel gain maps are useful for various sensing and resource allocation tasks essential for the operation of cognitive radio networks. In this paper, the channel gains are modeled as the tomographic accumulations of an underlying spatial loss field (SLF), which captures the attenuation in the signal strength due to the obstacles in the propagation path. In order to estimate the map accurately with a relatively small number of measurements, the SLF is postulated to have a low-rank structure possibly with sparse deviations. Efficient batch and online algorithms are derived for the resulting map reconstruction problem. Comprehensive tests with both synthetic and real data sets corroborate that the algorithms can accurately reveal the structure of the propagation medium, and produce the desired channel gain maps.
Combination of experimental and numerical methods for mechanical characterization of Al-Si alloys (2017)

In general, mechanical properties of Al-Si alloys strongly depend on the morphology and arrangement of microconstituents, such as primary aluminium dendrites, silicon particles, etc. Therefore, a detailed characterization of morphological and mechanical properties of the alloys is necessary to better understand the relations between the underlined properties and to tailor the material's microstructure to the specific application needs. The mechanical characterization usually implies numerical simulations and mechanical tests, which allow to investigate the influence of different microstructural aspects on different scales. In this study, the uniaxial tension and compression tests have been carried out on Al-Si alloys having different microstructures. The mechanical behavior of the alloys has been interpreted with respect to the morphology of the microconstituents and has been correlated with the results of numerical simulations. The advantages and limitations of the experimental and numerical methods have been disclosed and the importance of combining both techniques for the interpretation of the mechanical behavior of Al-Si alloys has been shown. Thereby, it has been suggested that the density of Si particles and the size of Al dendrites are more important for the strengthening of the alloys than the size-shape features of the eutectic Si induced by the modification.
CINS: Cell Interaction Network inference from Single cell expression data (2021)

Abstract Studies comparing single cell RNA-Seq (scRNA-Seq) data between conditions mainly focus on differences in the proportion of cell types or on differentially expressed genes. In many cases these differences are driven by changes in cell interactions which are challenging to infer without spatial information. To determine cell-cell interactions that differ between conditions we developed the Cell Interaction Network Inference (CINS) pipeline. CINS combines Bayesian network analysis with regression-based modeling to identify differential cell type interactions and the proteins that underlie them. We tested CINS on a disease case control and on an aging human dataset. In both cases CINS correctly identifies cell type interactions and the ligands involved in these interactions. We performed additional mouse aging scRNA-Seq experiments which further support the interactions identified by CINS.

Predictive value of psychatric history, genital pain and menstrual symptoms for sexuality after hysterectomy (1994)

Among variables studied, dysmenorrhea was the best predictor for postoperative sexuality. That is: women with dysmenorrhea do not only invariably experience relief from the pain, but also have a chance to improve their sexual lives after removal of their malfunctioning uterus. Presence of psychiatric problems had, in general, little influence on sexuality.
Outcome after liver re-transplantation in patients with recurrent chronic hepatitis C (2007)

Long-term outcome after liver retransplantation for recurrent hepatitis C has been reported to be inferior to other indications. The identification of factors associated which improved long-term results may help identify hepatitis C positive patients who benefit from liver retransplantation. Outcome after liver retransplantation for recurrent hepatitis C was analyzed in 18 patients (group 1) and compared with hepatitis C positive patients undergoing liver retransplantation for initial nonfunction (group 2, n=11) and patients with liver retransplantation for other indications (group 3, n=169). Five-year patient survival following retransplantation for groups 1, 2 and 3 was 59% 84% and 60%. Increased alanine aminotransferase (ALT) and serum bilirubin, as well as white cell count and MELD score at day of retransplantation were associated with impaired patient outcome. Five-year survival after retransplantation in patients with recurrent hepatitis C is similar to that in patients undergoing liver retransplantation for other indications. Our analysis showed MELD score, bilirubin, ALT levels and white cell counts preorthotopic liver transplantation are important predictive factors for outcome. This observational study may help select patients and identify the optimal time-point of liver retransplantation in ''Hepatitis C'' virus positive patients in the future.
Comparison of prothrombin time (INR) results and main characteristics of patients on warfarin treatment in primary health care centers and anticoagulation clinics (2013)

Oral anticoagulant therapy is used to prevent thrombosis in patients with atrial fibrillation (AF), venous thrombosis and prosthetic heart valves. The introduction of new therapies emphasizes the need to discern the best practice for the patients remaining on warfarin treatment. This study compares patient characteristics and therapeutic control in two settings managing warfarin treatment: Swedish primary health care centers (PHCC) and specialized anticoagulation clinics (ACC). Prothrombin time (PT) test results reported as International Normalized Ratio (INR) were collected for five consecutive days from patients on warfarin treatment; 564 PHCC and 927 ACC patients. Therapeutic control was calculated as PT test results in relation to intended therapeutic range (TR). Mann–Whitney Rank Sum Test and Chi2 test were used for statistical comparisons. The PHCC patients were older than the ACC patients, 76 v. 70 years (p<0.01) with a predominance of men in both groups. The reasons for treating differed between the groups. Seventy-two percent of PHCC patients and 66% of ACC patients had a PT-INR within the intended TR (p<0.05). Men generally had better results than women (72% v. 63%, p<0.001) and particularly in the PHCC group v. the ACC group (78% v. 69%, p<0.01). PT-INR above intended TR was significantly more common in the ACC setting, (p<0.05), for women overall (p<0.01), for women in the PHCC setting, and for ACC men (p<0.05). In this study both settings achieved good therapeutic control of warfarin treatment with a minor advantage for PHCC over ACC, and better results for men, especially in the PHCC setting. As patient characteristics differ between the PHCC and ACC, it is important to conduct further randomized studies to discern the best practice locally for warfarin management also after the introduction of new drugs.

Integrative Recombination--A Role for the Retroviral Reverse Transcriptase (1984)

Integration of retroviral DNA into host cell DNA is a normal step in the replication of retroviruses. Integrated proviruses and certain prokaryotic and eukaryotic transposable elements share several structural features (Cold Spring Harbor Symposia on Quantitative Biology 1981). This suggests that analogous reactions may be involved in transposition and integration, and models describing molecular aspects of retroviral DNA integration have drawn upon this analogy (Shoemaker et al. 1980).
<title>Image processing and low-discrepancy sequences</title> (1999)

It is well known that high-dimensional integral can be solved with Monte Carlo algorithms. Recently, it was discovered that there is a relationship between low discrepancy sets and the efficient evaluation of higher-dimensional integral. Theory suggests that for midsize dimensional problems, algorithms based on low discrepancy sets should outperform all other existing methods by an order of magnitude in terms of the number of sample points used to evaluate the integral. We show that the field of image processing can potentially take advantage of specific properties of low discrepancy sets. To illustrate this, we applied the theory of low discrepancy sequences to some relatively simple image processing and computer vision related operations such as the estimation of gray level image statistics, fast location of objects in a binary image and the reconstruction of images from a sparse set of points. Our experiments show that compared to standard methods, the proposed new algorithms are faster and statistically more robust. Classical low discrepancy sets based on the Halton and Sobol' sequences were investigated thoroughly and showed promising results. The use of low discrepancy sequences in image processing for image characterization, understanding and object recognition is a novel and promising area for further investigation.

Th1/Th2 CD4+ T cell responses against NY-ESO-1 in HLA-DPB1*0401/0402 patients with epithelial ovarian cancer. (2004)

The NY-ESO-1 antigen is expressed in a significant proportion of patients with epithelial ovarian cancer (EOC) and appears to be an ideal target for immunotherapy. In order to elucidate the nature of the HLA-DPB1*0401/0402 (DP4+)-restricted CD4+ immune response in patients with NY-ESO-1-expressing EOC, peripheral blood CD4+ T cells from HLA-DP4+ patients were stimulated with the NY-ESO-1 epitope 157-170 and tested for the release of type 1 (IFN-gamma) and type 2 (IL-5) cytokines in enzyme-linked immunospot assays. Of 14 DP4+ EOC patients who tested seronegative for NY-ESO-1, 3 patients had a detectable CD4+ T cell response to NY-ESO-1 epitope 157-170 by IFN-gamma ELISPOT assay. Six of 10 DP4+ EOC patients with serum antibodies to NY-ESO-1 had CD4+ T cell responses to NY-ESO-1 epitope 157-170 by IFN-gamma assay. Six patients had mixed Th1/Th2 CD4+ T cell responses to NY-ESO-1 epitope 157-170 regardless of their antibody response to NY-ESO-1. Four EOC patients had Th1 cells expressing IFN-gamma, but not IL-5. This suggests that the NY-ESO-1 epitope 157-170 stimulates both Th1 and Th2 type CD4+ T cell responses in EOC patients. These data suggest the NY-ESO-1 epitope 157-170 has a key role in the induction of cellular and humoral immune responses against NY-ESO-1-expressing EOC tumors. Our study supports the relevance of cancer vaccine trials with the NY-ESO-1 epitope 157-170 in HLA-DP4+ EOC patients with NY-ESO-1-expressing tumors and strategies to improve Th1-dominated tumor-reactive CD4+ T cell bias.
