High-power high-repetition-rate subpicosecond monolithic Yb:KGW laser with self-mode locking (2013)

We report on a high-power subpicosecond monolithic self-mode-locked Yb:KGW laser with the pulse repetition rate up to several tens of gigahertz. Experimental results reveal that not only the repetition rate but also the pulse width depend on the length of the laser crystal. Using a coated Yb:KGW crystal with a length of 3.36 mm, mode-locked pulses with pulse duration of 850 fs at the repetition rate of 22.4 GHz have been achieved. With an incident pump power of 10.5 W, an average output power of 3.6 W was achieved which corresponds to the optical conversion efficiency of 34.3%.
1128-P: SGLT2 Inhibition Increases Serum Copeptin in Adults with Type 1 Diabetes (T1D) (2019)

Elevated copeptin, a stable surrogate of vasopressin, is recognized to be higher in T1D and predicts diabetic kidney disease and cardiovascular (CV) mortality. Vasopressin increases renal oxygen consumption through enhanced sodium reabsorption and may result in renal hypoxia. Given the natriuretic and cardiorenal protective effects of SGLT2 inhibition (SGLT2i) in clinical trials, our aim was to: 1) examine serum copeptin in adults with T1D after SGLT2i with empagliflozin (EMPA) for 8-weeks; and 2) determine the relationship between copeptin and metabolic, renal and system hemodynamic parameters. In this post hoc, exploratory analysis, serum copeptin concentration, glomerular filtration rate (GFR) by inulin clearance, effective renal plasma flow (ERPF) by PAH clearance, vascular stiffness parameters, plasma RAAS markers, HbA1c, 24-hour urine volume and sodium and glucose excretion were measured in 40 participants with T1D (24.1±5.0 years, HbA1c 8.0±0.9%) during eu- and hyperglycemia at baseline and after 25 mg of daily EMPA. Copeptin concentrations increased under both eu- and hyperglycemic conditions (4.0±2.1 to 5.1±6.0 pmol/L, p=0.005 and p&amp;lt;0.0001, respectively) in response to EMPA. Higher copeptin concentrations were associated with higher HbA1c (β±SE: 0.97±0.30, p=0.003), lower 24h urine volume (β±SE: -3.08±1.05, p=0.006) and fractional sodium excretion (β±SE: -8.30±2.73, p=0.004), after correcting for age, sex, systolic blood pressure (SBP), and HbA1c. There were no significant relationships between copeptin and RAAS markers, vascular stiffness, renal or systemic hemodynamic parameters in fully adjusted models. SGLT2i increased serum copeptin concentrations, which positively correlated with HbA1c and inversely with urine output and natriuresis, but not with renal or system hemodynamic parameters. Further work is required to evaluate the clinical implications of elevated copeptin with SGLT2i; whether it is simply a marker of diuresis or may contribute to CV disease long-term. Disclosure Y.

Coaxial-Slot Surface Wave Launchers (1970)

The radiation characteristics of 360/spl deg/ circumferential slots in rigid dielectric-coated coaxial cable are studied both theoretically and experimentally. The ultimate aim of this work is to use an array of such slots to launch a surface wave on the Goubau line formed by the outer conductor of the coaxial cable and the concentric dielectric coating. The possible advantage of this method over that of the flared horn is that the launching efficiency is controlled by the length of the launchlng section and is relatively independent its cross-sectional area.
Demonstration of High-Speed 2 × 2 Non-Imaging MIMO Nyquist Single Carrier Visible Light Communication With Frequency Domain Equalization (2014)

We experimentally demonstrate a high-speed 2 × 2 non-imaging multiple-input multiple-output nyquist single carrier visible light communication system. Two commercially available blue light emitting diodes with 3 dB electrical bandwidth of 10 MHz and two avalanche photo diodes with 3 dB electrical bandwidth of 100 MHz are used as transmitters and receivers, respectively. A frequency domain equalization method based on two pairs of time-multiplexed training symbols is proposed, which allows de-multiplexing and post-equalization simultaneously processing in one step. Frequency domain averaging and time-domain averaging are also implemented and analyzed in this paper. In this demonstration, the overall data rate is 500 Mb/s. The measured bit error rates for two receivers are both below the 7% pre-forward-error-correction threshold of 3.8 ×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> after 40 cm free-air transmission.

Distributed Transmitter Optimization for the Wyner-Type Downlink via Belief Propagation (2014)

We study a Wyner-type downlink network, where any two adjacent base stations (BSs) can communicate with each other and cooperate on transmission of discrete data symbols to their intended mobile stations (MSs) situated along a circular array. With focus on the binary case, we take the symbol detection point of view and formulate a novel non-linear precoding optimization problem by imposing minimum Symbol Error Probabilities as Quality-of-Service constraints at MSs. We then cast the problem into a factor graph and propose a belief propagation (BP) framework to solve the problem in a distributed manner based on only local communication between adjacent BSs. Numerical results confirm the convergence of the distributed algorithm and demonstrate the transmit power saving from the proposed precoder over two state-of-the-art linear precoders. To the best of our knowledge, this is the first work that leverages the BP method for non-linear precoding.

We present the first report to the best of our knowledge of highly efficient phase conjugation in a laser-pumped polymer-dye saturable amplifier. Phase-conjugate reflectivity of as much as 210% at 560 nm has been obtained. Moreover, efficient reflectivity has been obtained in the broad wavelength region from 556 to 567 nm.
Machine Learning for Networking: Workflow, Advances and Opportunities (2017)

Recently, machine learning has been used in every possible field to leverage its amazing power. For a long time, the networking and distributed computing system is the key infrastructure to provide efficient computational resources for machine learning. Networking itself can also benefit from this promising technology. This article focuses on the application of MLN, which can not only help solve the intractable old network questions but also stimulate new network applications. In this article, we summarize the basic workflow to explain how to apply machine learning technology in the networking domain. Then we provide a selective survey of the latest representative advances with explanations of their design principles and benefits. These advances are divided into several network design objectives and the detailed information of how they perform in each step of MLN workflow is presented. Finally, we shed light on the new opportunities in networking design and community building of this new inter-discipline. Our goal is to provide a broad research guideline on networking with machine learning to help motivate researchers to develop innovative algorithms, standards and frameworks.

A theoretical and numerical study of the flow of granular materials down an inclined plane. Final report (1995)

The mechanics of the flowing granular materials such as coal, agricultural products, at deal of attention as it has fertilizers, dry chemicals, metal ores, etc. have received a great deal of attention as it has relevance to several important technological problems. Despite wide interest and more than five decades of experimental and theoretical investigations, most aspects of the behavior of flowing granular materials are still not well understood. So Experiments have to be devised which quantify and describe the non-linear behavior of the modular materials, and theories developed which can explain the experimentally observed facts. As many models have been suggested for describing the behavior of granular materials, from both continuum and kinetic theory viewpoints, we proposed to investigate the validity and usefulness of representative models from both the continuum and kinetic theory points of view, by determining the prediction of such a theory, in a representative flow, with respect to existence, non-existence, multiplicity and stability of solutions. The continuum model to be investigated is an outgrowth of a model due to Goodman and Cowin (1971, 1972) and the kinetic theory models being those due to Jenkins and Richman (1985) and Boyle and Massoudi (1989). In this report we present detailed results regarding the same. Interestingly, we find that the predictions of all the theories, in certain parameter space associated with these models, are qualitatively similar. This ofcourse depends on the values assumed for various material parameters in the models, which as yet are unknown, as reliable experiments have not been carried out as yet for their determination.
Sterics versus Electronics: Regioselective Cross‐Coupling of Polybrominated Thiophenes (2008)

Abstract Methods for the regioselective cross‐coupling of 2,3,5‐tribromothiophene have been developed in which selective aryl–aryl coupling occurs at the 5‐position with yields up to 63 %. The difference in reactivity of the α‐ and β‐positions then allows sequential regioselective couplings first at the 2‐position, followed by the 3‐position. Such regioselective cross‐coupling allows unprecedented control in the generation of trifunctionalized thiophenes. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2008)
Efficient FPGA Implementation of OpenCL High-Performance Computing Applications via High-Level Synthesis (2017)

FPGA-based accelerators have recently evolved as strong competitors to the traditional GPU-based accelerators in modern high-performance computing systems. They offer both high computational capabilities and considerably lower energy consumption. High-level synthesis (HLS) can be used to overcome the main hurdle in the mainstream usage of the FPGA-based accelerators, i.e., the complexity of their design flow. HLS enables the designers to program an FPGA directly by using high-level languages, e.g., C, C++, SystemC, and OpenCL. This paper presents an HLS-based FPGA implementation of several algorithms from a variety of application domains. A performance comparison in terms of execution time, energy, and power consumption with some high-end GPUs is performed as well. The algorithms have been modeled in OpenCL for both GPU and FPGA implementation. We conclude that FPGAs are much more energy-efficient than GPUs in all the test cases that we considered. Moreover, FPGAs can sometimes be faster than GPUs by using an FPGA-specific OpenCL programming style and utilizing a variety of appropriate HLS directives.
Performance of diversity systems with 2 and 4 transmit antennas (2002)

We investigate the principles of existing 2 transmit antenna systems and then introduce two new transmit antenna diversity configurations for 4-transmit antenna systems. The bit error rate performances of the proposed systems are obtained. We show that by using two more antennas and the same total transmit power, diversity gains of up to 5 dB can be achieved over 2-transmit antenna systems.
Abstract 1423: The addition of bevacizumab to chemoimmunotherapy prolongs progression-free survival in patients with chronic lymphocytic leukemia (CLL) through modulation of the microenvironment (2016)

Abstract Introduction. First-line chemoimmunotherapy (CIT) has significantly increased the complete remission (CR) rate for patients with CLL; however, relapse is a common event and strategies aimed at eradicating disease more effectively are needed. Vascular Epithelial Growth Factor (VEGF) plays a crucial role in the cross talk between CLL B cells and their microenvironment. In addition low baseline VEGF levels predict a better response to CIT. Testing the combination of an anti-VEGF agent with CIT was therefore assessed by us in upfront CLL patients. Methods. Here we report the results of a phase II open-label randomized trial comparing the combination of bevacizumab, an anti-VEGF monoclonal antibody, with pentostatin, cyclophosphamide and rituximab (PCR-B) to PCR alone as front-line therapy in previously untreated patients with CLL. VEGF, b-fibroblast growth factor (FGF), thrombospondin (TSP)-1, chemokine ligand (CCL)-3 and CCL-4 plasma levels were measured at baseline and at time of response assessment. Results. Between 01/2009 and 01/2013, 62 patients were accrued in the study, 32 in the arm A (PCR-B) and 30 in arm B (PCR alone). A higher rate of grade 3-4 cardiovascular toxicity was observed with the use of PCR-B (34% vs 0%, p&amp;lt;0.001): this included 7 cases of hypertension, 2 cases of congestive heart failure, 1 myocarditis, and 1 case of torsade de point. A higher CR rate (50% vs 33%, p = 0.21) and a significantly longer median progression-free (p = 0.04) and treatment-free (p = 0.05) survival were achieved with the use of PCR-B. No difference in chemokine kinetics was observed between the 2 arms, except for VEGF, which significantly increased after PCR-B. In the PCR-B arm, chemokine kinetics for CCL-3 (median drop 5.0 vs. median drop 31.8, respectively; p = 0.02) and CCL-4 (median drop 23.8 vs. median drop 120.9, respectively; p = 0.01) were significantly associated with achievement of CR. No significant correlations were found between cytokine plasma levels and responses for patients treated in the PCR only arm. Conclusions. The addition of bevacizumab to CIT is safe and effective, although associated with higher cardiovascular toxicity, in particular hypertension. The addition of bevacizumab produces higher CR rates, translating into improved progression-free survival, and is associated with decreased plasma levels of CCL-3 and CCL-4.

Microwave Dielectric Properties and Microstructures of Ca1-xNd2x/3TiO3–Li1/2Nd1/2TiO3Ceramics (2002)

The microwave dielectric properties and microstructures of (1-y)Ca1-xNd2x/3TiO3–yLi1/2Nd1/2TiO3 ceramics, prepared by a mixed oxide route, have been investigated. A maximum quality factor Q×f=8600 GHz (where f is the resonant frequency) was achieved for samples with y=0 and x=0.39, although the dielectric properties varied with sintering temperature. The Q×f value of (1-y)Ca1-xNd2x/3TiO3–yLi1/2Nd1/2TiO3 increased up to 1400°C, after which it decreased. The decrease in dielectric properties was coincident with the onset of rapid grain growth. In the (1-y)Ca1-xNd2x/3TiO3–yLi1/2Nd1/2TiO3 system, as y increased, the temperature coefficient of resonant frequency (τf) decreased from 800 to 8 ppm/°C for y=0.52 (x=0.39). However, the optimum combination of microwave dielectric properties was achieved at 1400°C for samples where y=0.45 (x=0.39) with a dielectric constant εr of 101, a Q×f value of 5300 (at 7.2 GHz) and a τf value of +13 ppm/°C.

Procurement and Identification of HL‐A Lymphocytotoxic Antibodies in Sera of Nonpregnant, Multiparous Blood Donors (1974)

An efficient procedure for large-scale screening of nonpregnant multiparous blood donor sera is described. Yield of useful HL-A reagents in this population compares favorably to yields obtained from screening pregnant women near term. The advantages of screening nonpregnant donors include stable antibody titers, ease of procurement, and the willingness of voluntary blood donors to return for plasmapheresis.
Improved light transmission in nanocrystalline aluminum nitride (AlN)—Enabling a lightweight, thermal shock resistant transparent ceramic (2022)

Optically transparent ceramics were traditionally only viable using optically isotropic materials and limited birefringent materials with small Δn such as alumina (Δn≈0.008). Thus heavily birefringent materials such as AlN (Δn≈0.045), polycrystalline ceramics are usually not considered for optical applications due to their high scattering loss, despite its exceptionally appealing thermal conductivity, mechanical stiffness/toughness and relatively low density—attributes that are ideal for light weight optical windows for harsh environments. To further improve the transparency over coarse grain AlN ceramics that have been reported, subwavelength grain size is desired. Here we present significant improvements in visible, NIR and mid-IR transparency in AlN ceramics by reducing the average grain size to 230 nm. A newly developed, non-carbon thermal reduction for producing clean powders at low temperatures is key to the success. The nanocrystalline AlN ceramics reach full density at a densification temperature as low as 1500 °C and showed an in-line transparency of over 55% at 2.5 μm and over 70% in the mid-IR which is the highest transparency in AlN ceramics reported. The successful demonstration of transparent nanocrystalline AlN ceramics makes it the ideal choice for optical windows in quickly fluctuating temperature environments where weight is a consideration such as air and space vehicles.
