Reliability Accelerated Testing of MEMS Acccelerometers (2007)

An attempt to assess the reliability of a batch of MEMS accelerometers is presented. The testing plan is application oriented and contains combined tests: thermal and mechanical stresses (two variants: vibration and tilting) were used. The results demonstrated the good reliability of the tested device, the failure rate being smaller than 6.10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-8</sup> h <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> .
Contact Stress and Linearized Modal Predictions of As-Built Preloaded Assembly (2020)

Abstract The member stiffness and pressure distribution in a bolted joint is significantly influenced by the contact area of the mechanical interface under a prescribed preload force. This research explores the influence of as-built surface profiles for nominally flat interfaces of a C-Beam assembly with two well-defined contact regions. A high-fidelity finite element model is created such that the model uncertainty is minimized by updating and calibrating the piece parts prior to the preload assembly procedure. The model is then assembled and preloaded to evaluate the contact stresses and contact area for both nominally flat and perturbed non-flat surfaces based on three-dimensional surface topography measurements. The predicted pressures are validated with digitized pressure-sensitive film measurements. The high-fidelity modeling reveals how the compliance and thickness of the pressure-sensitive film alter the measured pressures, leading to incorrect evaluations of the stresses and contact area in the joint. The resulting low-level dynamic behavior of the preloaded assembly is shown to be sensitive to the true contact area by linearizing the nonlinear finite element model about the preloaded equilibrium and performing a computational modal analysis. The resonant frequencies are validated with experimental measurements to demonstrate the effect of the contact area on the modal characteristics of the bolted assembly. Vibration modes and loading patterns exhibit varying levels of sensitivity to the contact area in the joint, leading to an improved physical understanding of the influence of contact mechanics on the low-level linear vibration modes of jointed assemblies.
Monocyte-specific Bcl-2 expression attenuates inflammation and heart failure in monocyte chemoattractant protein-1 (MCP-1)-induced cardiomyopathy☆ (2006)

These results demonstrate that apoptosis of infiltrating mononuclear cells plays a detrimental role in the development of heart failure in this murine model, suggesting that modulation of apoptosis of infiltrating mononuclear cells may be of clinical benefit in heart failure.
Wave Loads on a Point-Absorbing Wave Energy Device in Extreme Waves (2015)

The survivability of a 1:20 scale point-absorbing Wave Energy Converter (WEC) model is considered in extreme wave tests with focused waves embedded in regular wave backgrounds and with time series of irregular waves. The wave heights were many times higher than the maximal stroke length of the device. Three different float geometries were used in the tests. The peak loads were measured and compared for extreme waves embedded in background waves with a range of periods and phase relations and with different values of Power Take-Off (PTO) damping.
Transcript of a Five-Member Committee Experiment (1976)

The following pages contain the transcript of a committee experiment of the type first introduced by Fiorina and Plott [ 1]. The subjects, law students in their second year of study were very articulate, sensitive to moral concerns, and skilled in strategic behavior. Their conversations, debates and reflections might provide a good source of data for scholars seeking to explain the equilibrium decision made by similar groups. The transcript may also provide some experience for those interested in field applications of laboratory results with the type of social environment within which mathematical models are known to work.
Sedationless Colonoscopy With Visualization Balloon: First Clinical Experience In Humans (2014)

Introduction: During traditional colonoscopy, abdominal pain is caused by distention of the colon with carbon dioxide (CO2) or air and stretching of the colonic wall and mesentery while advancing the colonoscope to the cecum. A recently developed proprietary visualization balloon, (Vizballoon™), was created to advance a colonoscope without gas insufflations, eliminating colon distention and creation of colonic loops, and allowing to reach the cecum faster than during traditional colonoscopy. Methods: We performed sedationless colonoscopies using Vizballoon™ without any CO2 or air insufflation. Vizballoon™ was inserted through the biopsy channel of adult colonoscope (CF 190, Olympus, Tokyo, Japan) and filled with 5 mL of water. The colonoscope was inserted into the rectum and advanced until the cecum was identified by either the appendicular orifice or the ileocecal valve. Once the cecum was entered, the balloon was collapsed and removed. Then CO2 was insufflated to visualize the colonic lumen during withdrawal of the colonoscope. Results: Sedationless colonoscopy with assistance of the Vizballoon™ was performed in 3 patients. Advancement of the colonoscope with Vizballoon™ was technically easy. None of the patients required any external pressure or position change to reach the cecum. All patients reported only mild discomfort (pain assessment scale less than 4) during colonoscope advancement, which was easily eliminated by pulling back the colonoscope and shortening the colon. On withdrawal of the colonoscope, CO2 insufflation was used to maintain adequate visualization of the colonic lumen and did not cause any abdominal discomfort. None of the study patient reported abdominal pain after completion of the colonoscopy. All study patients expressed a desire to repeat Vizballoon™-assisted, sedationless colonoscopy in the future. Conclusion: Sedationless colonoscopy with assistance of visualization balloon is fast, technically easy, and could become a future standard for screening colonoscopy.
Pilot Plant Reliability Metrics for Grinding and Fast Pyrolysis of Woody Residues (2020)

Here, we report on the effects of loblolly pine residue variability on material throughput, pilot plant uptime, operator intervention, product yield, and product quality for grinding, fast pyrolysis, and hydrotreating operations. Preprocessing throughput using a hammer mill varied between 31 and 48% of nameplate capacity (5 tons/h). Grinder overloads in the size reduction step were more prevalent for lower ash and higher moisture materials. Fast pyrolysis throughput varied between 57 and 72% of nameplate capacity (20 kg/h), and bio-oil yields varied between 46 and 53% (feedstock carbon to oil, dry basis). During fast pyrolysis operations, downtime was caused by bridging in the feed and char removal systems and plugging in the condensation system. Cohesion of feedstock and char leading to system plugging was less frequent for higher ash feedstocks, and differences in condenser plugging behavior between high and low ash feedstocks were observed. The catalyst stability of the bio-oil stabilization step was strongly dependent on the sulfur content in the bio-oil, which was higher for the high-ash residue oils. Lower moisture content in the starting biomass was consistent with lower sulfur content in bio-oil. Yields and properties of hydrotreated fuel products showed minimal deference among the bio-oils.

Optically Active Metasurface with Non-Chiral Plasmonic Nanoantennas (2014)

We design, fabricate, and experimentally demonstrate an optically active metasurface of λ/50 thickness that rotates linearly polarized light by 45° over a broadband wavelength range in the near IR region. The rotation is achieved through the use of a planar array of plasmonic nanoantennas, which generates a fixed phase-shift between the left circular polarized and right circular polarized components of the incident light. Our approach is built on a new supercell metasurface design methodology: by judiciously designing the location and orientation of individual antennas in the structural supercells, we achieve an effective chiral metasurface through a collective operation of nonchiral antennas. This approach simplifies the overall structure when compared to designs with chiral antennas and also enables a chiral effect which quantitatively depends solely on the supercell geometry. This allows for greater tolerance against fabrication and temperature effects.
Data from Selective and Concentrated Accretion of SN-38 with a CEACAM5-Targeting Antibody–Drug Conjugate (ADC), Labetuzumab Govitecan (IMMU-130) (2023)

&lt;div&gt;Abstract&lt;p&gt;Labetuzumab govitecan (IMMU-130), an antibody–drug conjugate (ADC) with an average of 7.6 SN-38/IgG, was evaluated for its potential to enhance delivery of SN-38 to human colonic tumor xenografts. Mice bearing LS174T or GW-39 human colonic tumor xenografts were injected with irinotecan or IMMU-130 (SN-38 equivalents ∼500 or ∼16 μg, respectively). Serum and homogenates of tumors, liver, and small intestine were extracted, and SN-38, SN-38G (glucuronidated SN-38), and irinotecan concentrations determined by reversed-phase HPLC. Irinotecan cleared quickly from serum, with only 1% to 2% injected dose/mL after 5 minutes; overall, approximately 20% was converted to SN-38 and SN-38G. At 1 hour with IMMU-130, 45% to 63% injected dose/mL of the SN-38 was in the serum, with &gt;90% bound to the ADC over 3 days, and with low levels of SN-38G. Total SN-38 levels decreased more quickly than the IgG, confirming a gradual SN-38 release from the ADC. AUC analysis found that SN-38 levels were approximately 11- and 16-fold higher in LS174T and GW-39 tumors, respectively, in IMMU-130–treated animals. This delivery advantage is amplified &gt;30-fold when normalized to SN-38 equivalents injected for each product. Levels of SN-38 and SN-38G were appreciably lower in the liver and small intestinal contents in animals given IMMU-130. On the basis of the SN-38 equivalents administered, IMMU-130 potentially delivers &gt;300-fold more SN-38 to CEA-producing tumors compared with irinotecan, while also reducing levels of SN-38 and SN-38G in normal tissues. These observations are consistent with preclinical and clinical data showing efficacy and improved safety. &lt;i&gt;Mol Cancer Ther; 17(1); 196–203. ©2017 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;

Dynamic Meshing Using Adaptively Sampled Distance Fields (2001)

Many models used in real-time graphics applications are generated automatically using techniques such as laser-range scanning. The resultant meshes typically contain one or more orders of magnitude more polygons than can be displayed by today´s graphics hardware. Numerous methods have been proposed for automatically creating level-of-detail (LOD) meshes from large input meshes. These techniques typically generate either one or more static LOD meshes, precomputed before use in the application, or a dynamic mesh, where the LOD of the mesh adapts to frame rate requirements. We present a new dynamic LOD technique ideal for applications such as games and physical simulations based upon Adaptively Sampled Distance Fields (ADFs).
35.2 A 0.021mm2 PVT-Aware Digital-Flow-Compatible Adaptive Back-Biasing Regulator with Scalable Drivers Achieving 450% Frequency Boosting and 30% Power Reduction in 22nm FDSOI Technology (2021)

A near-threshold power supply aims to operate at the minimal energy point but suffers from high-sensitivity to process, temperature and voltage variations. Adaptive voltage scaling (AVS) is a well-known strategy to adapt the power supply to die-to-die and temperature variations [1]. However, AVS needs dedicated power supplies with nonnegligible overheads, e.g. extra die area, lower power converter efficiency, and with granularity limitations or complex fine-grain integration in the power mesh. SOI-based technologies offer unique features by biasing the wells below the transistors to tune the threshold voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TH</sub> ). The well-known adaptive back-biasing (ABB) technique has already shown its capability to reduce power consumption or/and maintain operating frequency by compensating V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TH</sub> variability according to process corners and temperature [1-5]. However, previously published ABB architectures provide a limited overview on how to integrate the ABB seamlessly in the digital design flow with industrial-grade qualification. We propose a reusable ABB-IP for any biased digital load, from 0.4-100 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , with low area and power overhead, e.g. 1.2% @ 2mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 0.4% @ 10mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , respectively. We properly quantify the gain in a mass-production context with a large statistical scope analysis across 316 measured dies from different split-wafer lots and from -40 to 125°C with a representative load (a Cortex M4F). Thanks to 3V asymmetrical wells amplitude swing, our ABB-IP brings up to 30% power reduction by decreasing the minimal power supply by 100mV, while maintaining the target operating frequency (50 MHz) with a high yield. Distributed timing monitors (DTM) guarantee an accurate timing monitoring of the biased digital load, while scalable well drivers adjust to the biased well area, enabling the ABB-IP genericity.
Channel Frequency Response Estimation Under the Effect of RF Impairements in OFDM Based Wireless Systems (2006)

In this paper, the effects of various analog front-end impairments on the estimation of channel response for OFDM based wireless communication systems were discussed. Then, channel estimation algorithms that can take these effects into account were suggested. It was shown that the analog-front end impairments affect the performance of channel estimators greatly. However, with careful channel estimation algorithm designs, these effects can be minimized or completely compensated.
Big data skipping in the cloud (2019)

According to today's best practices, cloud compute and storage services should be deployed and managed independently. However, this generates a problem for big data analytics in the cloud: potentially huge datasets need to be shipped from the storage service to the compute service to analyse the data. To address this, minimizing the amount of data sent across the network is critical to achieve good performance and low cost. Data skipping is a technique which achieves this for SQL style analytics on structured data.
Restoration of error-diffused images using projection onto convex sets (2001)

A novel inverse halftoning method is proposed to restore a continuous tone image from a given half-tone image. A set theoretic formulation is used where three sets are defined using the prior information about the problem. A new space-domain projection is introduced assuming the halftoning is performed using error diffusion, and the error diffusion filter kernel is known. The space-domain, frequency-domain, and space-scale domain projections are used alternately to obtain a feasible solution for the inverse halftoning problem which does not have a unique solution.

Signals in the Silence: Models of Implicit Feedback in a Recommendation System for Crowdsourcing (2014)

We exploit the absence of signals as informative observations in the context of providing task recommendations in crowdsourcing. Workers on crowdsourcing platforms do not provide explicit ratings about tasks. We present methods that enable a system to leverage implicit signals about task preferences. These signals include types of tasks that have been available and have been displayed, and the number of tasks workers select and complete. In contrast to previous work, we present a general model that can represent both positive and negative implicit signals. We introduce algorithms that can learn these models without exceeding the computational complexity of existing approaches. Finally, using data from a high-throughput crowdsourcing platform, we show that reasoning about both positive and negative implicit feedback can improve the quality of task recommendations.
A Fixed Switching Frequency Dual-Input LLC Converter with PWM Controlled Semi-Active Rectifiers for PV Applications (2021)

This paper proposes a new modulation for a dual-input LLC resonant converter with semi-active rectifiers that interfaces with two PV panels. This topology is a dual half-bridge LLC circuit with four active switches on the primary and a full-bridge rectifier with two diodes and two switches on the secondary. Instead of using the traditional pulse-frequency modulation (PFM) to control the converter voltage gain; in this new modulation, the duty cycle of the secondary switches is varied to maintain the output voltage at the desired value while the switching frequency is always kept at the same value as the resonant frequency, so that the switching loss can be reduced. A phase-shift pulse-width modulation (PWM) control for primary switches is still employed to implement maximum power point tracking (MPPT) for PV panels. Soft switching is realized in all switches over the entire range of source voltage and load conditions. A 500-W prototype was built to validate the behaviors of the proposed modulation. The input voltage range of each PV source was selected to be 25 V to 40 V and the output voltage was regulated at 200 V DC. Experimental results are closely matching the theoretical analysis.
Genetic variants in thyroid cancer distant metastases (2016)

Thyroid carcinoma is the most rapidly increasing solid tumor in the United States; although there has been a great emphasis on the analysis of primary tumors, predictors of both late-stage progression and response to therapy are more poorly defined due in part to the scarcity of progressive metastatic tissues. Therapeutic evidence of mixed responses in metastatic lesions and the limited available genomic data suggest that distant metastases in thyroid cancer are heterogeneous, driven by known oncogenes and other pathways that also might be therapeutic targets. We analyzed the genomes of a small number of rare surgically resected metastatic thyroid cancer lesions along with paired normal and primary tumor samples when available, in an effort to better characterize progressive distant metastases. The findings confirm the presence of mutations to known tumor drivers (BRAF and RAS) in metastatic samples. The results also identified the co-occurrence in predicted functional variants to the DNA damage repair (DDR) genes ATM and ERCC4 in metastatic lesions that did not show alterations of the MAPK pathway.&#13;\n&#13;\nWe examined the exomes of 19 samples (including 5 paired normal tissues) from 11 follicular cell-derived thyroid cancer patients with surgically resected distant metastases by custom exomeSeq (Supplementary Materials and Methods, see section on supplementary data given at the end of this article). Tumors with different histopathologies were included and were confirmed by an expert thyroid pathologist (PW). All patients were treated with TSH suppression, eight of them received I-131 therapy and none of them received chemotherapy or kinase inhibitors. Overall, 19,299 unique variants in the 682 genes and genomic regions were identified by an exomeSeq custom panel. We sought to identify rare, conserved, exonic variants that were likely to have functional effects. Thus, we focused on 1742 exonic variants in exons of sequenced genes. We excluded synonymous variants and ...
