Biologically inspired climbing with a hexapedal robot (2008)

Abstract This paper presents an integrated, systems‐level view of several novel design and control features associated with the biologically inspired, hexapedal, RiSE (Robots in Scansorial Environments) robot. RiSE is the first legged machine capable of locomotion on both the ground and a variety of vertical building surfaces including brick, stucco, and crushed stone at speeds up to 4 cm/s, quietly and without the use of suction, magnets, or adhesives. It achieves these capabilities through a combination of bioinspired and traditional design methods. This paper describes the design process and specifically addresses body morphology, hierarchical compliance in the legs and feet, and sensing and control systems that enable robust and reliable climbing on difficult surfaces. Experimental results illustrate the effects of various behaviors on climbing performance and demonstrate the robot's ability to climb reliably for long distances. © 2008 Wiley Periodicals, Inc.
Tracking Forecast Memories in stochastic decoders (2009)

This paper proposes tracking forecast memories (TFMs) as a novel method for implementing re-randomization and decorrelation of stochastic bit streams in stochastic channel decoders. We show that TFMs are able to achieve decoding performance similar to that of the previous methods in the literature (i.e., edge memories or EMs), but they exhibit much lower hardware complexity. TFMs significantly reduce the area requirements of ASIC implementations of stochastic decoders.
Implantable and Bioresorbable Nanostructured Fluorescence Sensor for In vivo pH Monitoring (2022)

Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore conformably deposited within a porous silica membrane—thickness of a few micrometers—to increase fluorescence intensity up to 600 times and enable reliable measurements through skin.
Very-high-bandwidth In/sub 0.53/Ga/sub 0.47/As p-i-n detector arrays (1991)

The authors fabricated and packaged 1*4 arrays of In/sub 0.53/Ga/sub 0.47/As p-i-n photodetectors connected in a GaAs FET bias-switched, common cathode circuit. The bandwidth of the discrete (packaged) photodiodes in the arrays exceeds 11 GHz, and is 5 GHz for the packaged arrays. The on/off isolation ratio for fully packaged arrays using GaAs FET bias switches was measured at both low and high frequencies. It was found that the on/off isolation of the detectors in the array was 70 dB, and the bias switching times were less than 5 ns. The performance characteristics suggest that the p-i-n detector arrays used in a common cathode, current summing configuration have applications for high-freqeuncy digital and analog optical switching applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Correlation of Oxygen Anion Redox Activity to In‐Plane Honeycomb Cation Ordering in NaxNiyMn1−yO2 Cathodes (2022)

Sodium‐ion batteries (SIBs) are one of the most promising next‐generation energy storage systems because of their abundant and low‐cost component materials. However, the lower energy density of SIBs compared with lithium‐ion batteries diminishes their practical value proposition. Among the many sodium‐based cathodes, layered transition metal oxides with high sodium content have energy densities comparable with the lithium‐ion battery technology. When charged above 4.1 V, the sodium‐based cathodes often undergo transformations because the activation of oxygen anion redox causes irreversible oxygen release, transition metal ion migration, lattice distortion, and rapid capacity decay. Here, in situ gas analysis is performed to evaluate the lattice oxygen anion redox activity in Na x Ni y Mn 1− y O 2 cathodes with P2 and O3 structural orderings. Operando X‐ray diffraction and neutron diffraction are performed to assess the structural changes related to lattice oxygen redox and transition metal ion migration in Na x Ni y Mn 1− y O 2 cathodes. The results unveil that in‐plane honeycomb cationic ordering can help suppress oxygen anion redox activity, which is critical for the future design of layered transition metal oxide cathodes that are prone to achieve high‐energy for durable SIBs.
Web-Scale Semantic Ranking (2014)

Semantic ranking models go beyond keyword matching to score documents based on closeness in meaning to the query. The use of semantic ranking in Web search has been limited due to the high cost of these models. To address this issue, we have designed and implemented a new Web-scale ranking system that enables us to integrate semantic ranking techniques into a commercial search engine. We have explored several types of models and will describe our implementation of translation models (TM) in this paper. The experiments demonstrate that these models significantly improve relevance over our existing baseline system. Our new ranking system is deployed online and is currently serving many millions of users.

Data from Multiple Roles for the Receptor Tyrosine Kinase Axl in Tumor Formation (2023)

&lt;div&gt;Abstract&lt;p&gt;A focus of contemporary cancer therapeutic development is the targeting of both the transformed cell and the supporting cellular microenvironment. Cell migration is a fundamental cellular behavior required for the complex interplay between multiple cell types necessary for tumor development. We therefore developed a novel retroviral-based screening technology in primary human endothelial cells to discover genes that control cell migration. We identified the receptor tyrosine kinase Axl as a novel regulator of endothelial cell haptotactic migration towards the matrix factor vitronectin. Using small interfering RNA–mediated silencing and overexpression of wild-type or mutated receptor proteins, we show that Axl is a key regulator of multiple angiogenic behaviors including endothelial cell migration, proliferation, and tube formation &lt;i&gt;in vitro&lt;/i&gt;. Moreover, using sustained, retrovirally delivered short hairpin RNA (shRNA) Axl knockdown, we show that Axl is necessary for &lt;i&gt;in vivo&lt;/i&gt; angiogenesis in a mouse model. Furthermore, we show that Axl is also required for human breast carcinoma cells to form a tumor &lt;i&gt;in vivo&lt;/i&gt;. These findings indicate that Axl regulates processes vital for both neovascularization and tumorigenesis. Disruption of Axl signaling using a small-molecule inhibitor will hence simultaneously affect both the tumor and stromal cell compartments and thus represents a unique approach for cancer therapeutic development.&lt;/p&gt;&lt;/div&gt;
COMPARISON OF FEATURE SIGNIFICANCE QUANTILE APPROXIMATIONS (2004)

Summary Curve estimates and surface estimates often contain features such as inclines, bumps or ridges which may signify an underlying structural mechanism. However, spurious features are also a common occurrence and it is important to identify those features that are statistically significant. A method has been developed recently for recognising feature significance based on the derivatives of the function estimate. It requires simultaneous confidence intervals and tests, which in turn require quantiles for the maximal deviation statistics. This paper reviews and compares various approximations to these quantiles. Applying upcrossing‐probability theory to this problem yields better quantile approximations than the use of an independent blocks method.
Modular Porous Metal Augments for Treatment of Severe Acetabular Bone Loss during Revision Hip Arthroplasty (2004)

Modular acetabular augments were implanted in 16 patients (16 hips) for support of an uncemented hemispheric acetabular component during revision acetabular reconstruction. Based on the classification of Paprosky, acetabular bone defects were classified as 2A in one hip, 2B in three hips, 2C in one hip, 3A in five hips, and 3B in six hips. Preoperatively, the prosthetic femoral head centers were located at a mean horizontal distance of 18.6 mm (range, -3-46 mm), and a mean vertical distance of 27.6 mm (range, -16-52 mm) from the approximate femoral head center. Postoperatively, the prosthetic femoral head centers were located at a mean horizontal distance of 10.4 mm (range, 1-25 mm), and a mean vertical distance of 7.4 mm (range, -15-25 mm). At final followup, no implant had evidence of migration or loosening. At early clinical followup, this modular acetabular augment system seems helpful in acetabular reconstructions that cannot be treated with an uncemented hemispheric cup that would have required other forms of treatment such as structural allografts, acetabular cages, bilobed acetabular components, or custom acetabular components. Longer term followup is required to determine whether there are untoward effects of using a modular acetabular reconstructive system.

Abstract 1768: Identification of a potent, orally-available SMARCA2/4 inhibitor with in vitro and in vivo activity in preclinical models of SMARCA4-mutant NSCLC (2020)

Abstract SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin subfamily A member 2 (SMARCA2) is an ATP-dependent DNA helicase and a catalytic component of the SWI/SNF complex. SWI/SNF-mediated nucleosome remodeling is a critical regulator of chromatin accessibility resulting in transcriptional regulation of gene sets that determine and maintain cell state. The role of SMARCA2 as the catalytic driver of SWI/SNF activity is mutually exclusive with that of its close paralog, SMARCA4. Loss of functional SMARCA4, as is reported in a subset of NSCLC and other cancer types generally confers a dependency on SMARCA2. Cancers lacking functional SMARCA4 have been shown to be sensitive to loss of SMARCA2 function either through genetic ablation or the use of a small molecule SMARCA2/4 inhibitor. We describe the identification and characterization of a small molecule SMARCA2/4 inhibitor Compound 1 and its selective activity in the SMARCA4-mutant setting both in in vitro and in vivo model systems. The compound demonstrates inhibition of SMARCA2 and SMARCA4 enzymatic activity in biochemical assays and broad selectivity against other helicases. Selective sensitivity in anti-proliferative assays of 15-fold was observed in NSCLC cell lines with SMARCA4 protein loss compared to those harboring WT SMARCA4 protein. Oral dosing demonstrates dose-dependent in vivo SMARCA2 inhibition and anti-tumor activity in SMARCA4-mutant NSCLC xenograft models. This compound is suitable for further exploration of the role of SMARCA2/4 and SWI/SNF in vitro and in vivo in cancer and other indications. Citation Format: Allison E. Drew, Suzanne L.

Progress towards high-power Li/CFxbatteries: electrode architectures using carbon nanotubes with CFx (2015)

Carbon monofluoride (CFx) has a high energy density, exceeding 2000 W h kg(-1), yet its application in primary lithium batteries is limited by its power capability. Multi-walled carbon nanotubes (CNTs) are appealing additives for high-power batteries, due to their outstanding electronic transport properties, high aspect ratio necessitating low volume fraction for percolation, and high tensile strength. This perspective describes the current state of the art in lithium-carbon monofluoride (Li/CFx) batteries and highlights the opportunities for the development of high-power Li/CFx batteries via utilization of carbon nanotubes. In this report, we generated several electrode architectures using CFx/CNT combinations, and demonstrated the effectiveness of CNTs in enhancing the rate capability and energy density of Li/CFx batteries. First, we investigated the resistivity of CFx combined with CNTs and compared the CFx/CNT composites with conventional carbon additives. Second, we built CFx-CNT electrodes without metallic current collectors using CNTs as substrates, and compared their electrochemical performance with conventional CFx electrodes using aluminum foil as a current collector. Furthermore, we fabricated multi-layered CNT-CFx-CNT composite electrodes (sandwich electrodes) and studied the impact of the structure on the performance of the electrode. Our work demonstrates some of the opportunities for utilization of CNTs in CFx electrodes and the resultant implementation of CFx as a battery cathode in next-generation high-power batteries.
First image from a combined positron emission tomography and field‐cycled MRI system (2011)

Combining positron emission tomography and MRI modalities typically requires using either conventional MRI with a MR-compatible positron emission tomography system or a modified MR system with conventional positron emission tomography. A feature of field-cycled MRI is that all magnetic fields can be turned off rapidly, enabling the use of conventional positron emission tomography detectors based on photomultiplier tubes. In this demonstration, two photomultiplier tube-based positron emission tomography detectors were integrated with a field-cycled MRI system (0.3 T/4 MHz) by placing them into a 9-cm axial gap. A positron emission tomography-MRI phantom consisting of a triangular arrangement of positron-emitting point sources embedded in an onion was imaged in a repeating interleaved sequence of ∼1 sec MRI then 1 sec positron emission tomography. The first multimodality images from the combined positron emission tomography and field-cycled MRI system show no additional artifacts due to interaction between the systems and demonstrate the potential of this approach to combining positron emission tomography and MRI.

A novel entry to 5a-carba-hexopyranoses from carbohydrates based on a 6-exo-dig radical cyclization: synthesis of 5a-carba-β-d-mannopyranose pentaacetate (1999)

Carbohydrate-derived 2,3:4,6-diacetonides which are homologated at C-1 by reaction with phenyl acetylide undergo a 6-exo-dig radical cyclization, from a radical located at C-5, to yield highly functionalized cyclohexanes that are correlated with carba-sugars.
Diamond Power Electronics: From 1kV towards 10kV Breakdown Voltage (2022)

The rapidly growing demand for power electronics to rout, control, and convert electrical power motivates recent research into devices based on ultra-wide-bandgaps semiconductors. Diamond-based semiconductor devices have drawn increasing attention in high-power applications due to diamond’s extraordinary electrical and physical properties. It has a 5.5 eV band gap and over 7.7MV cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> breakdown field. Diamond is also one of the best thermal conductors with thermal conductivity over 2200 Wm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> k <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> , making it an ideal material for high power applications where heat dissipation is challenging [1]. To demonstrate diamond’s advantages in power electronics, diamond power diodes and transistors are fabricated with breakdown voltages much higher than devices based on other wide band-gap materials.
Detection of Misplaced Stationary RFID Tags (poster) (2019)

A smart shelving system can visualize stock data in real time by leveraging item-level RFID tagging. The detection of misplaced tags on stationary shelved items is very challenging due to position ambiguity, phase wrapping, device diversity, and phase ambiguity. We propose an effective way of detecting misplaced tags, called FINDS, that requires neither antenna movement nor external disturbances.
Modeling Magnetic Transport of Nanoparticles with Application to Magnetofection (2008)

We present a model for predicting the transport and accumulation of magnetic nanoparticles in magnetophoretic systems. The model involves the solution of a drift- diffusion equation that governs the concentration of nanoparticles in a fluidic chamber. We solve this equation numerically using the finite volume method. We apply the model to the magnetofection process wherein the magnetic force produced by a rare-earth magnet attracts magnetic carrier particles with surface-bound gene vectors toward target cells for transfection. We study particle accumulation as a function of key variables.
Polymorphic Transformation of γ-Fe2O3 by Isothermal Ball-Milling and Vacuum Hot-Pressing (1971)

粉体の多形転移反応におよぼす機械的外力の効果を定量的にとらえる試みとして,γ-Fe2O3の恒温湿式ボールミルおよび真空ホットプレスによるα-Fe2O3への転移過程を速度論的に追究した。その結果,機械的外力を加えることによって転移過程に適用される速度式が変わり,したがって転移の機構が外力を加えることにより変化するものと推論された。また,機械的外力の増大にともなって転移の活性化エネルギーが減少することから,機械的外力は欠陥の発生などを促し,反応物のポテンシャルエネルギーを高める役割を果たすことが推測された。さらに,既報のPbOのmassicot→litharge転移に対する同様な実験結果との比較から,機械的外力は相手の物質によって少なくとも二つの異なる効果によって多形転移を促進するが,外力の伝達機構はほとんど変化しないことが明らかとなった。
Analysis Self-Healing of Gate Leakage Current due to Oxide Traps to Improve Reliability of Gate Electrode (2017)

To achieve robust SiC-MOSFET, reliability of the gate insulator was investigated in terms of gate electrode edge treatment. Analytical calculation showed that r should be larger than the thickness of gate insulator to relax the electric field concentration. We obtained the rounded gate edge by dry oxidation at 1000°C, while oxidation at 800°C had it sharpened. Former samples exhibited low leakage current with Time-Zero-Dielectric-Breakdown (TZDB) measurement. I g consisted of Fowler-Nordheim (FN) tunneling current for V g &gt; 0, and it includes excess components for V g &lt; 0. We confirmed that they occurred at the gate edge and that they coursed positively charged trap centers in oxide near poly-Si/SiO 2 interface which caused local barrier lowering. Electron injection removed them by tunneling/recombination process, which followed tunneling-front model.
Local thermal analysis of reaction and the glass transition in exposed resist (1999)

We report the results of an in situ study of reaction and the glass transition in exposed films of positive chemically amplified resists. Local thermal analysis was performed on exposed patterns in thin films of APEX-E. We measure the activation energy of reaction int he exposed resist to be 132 +/- 5 kJ/mol. Post-exposure delay effects were shown to reduce the reaction rate in the pattern by as much as 14 percent. Finally, we used local thermal analysis to determine the effect of reaction on the glass transition temperature in exposed APEX-E. We find that the glass transition temperature increased linearly by as much as 20 degrees C after complete de-protection matrix. We present a detailed examination of the use of differential thermal analysis to study reaction and the glass transition with a local thermal probe.
Connective negation and negative concord in Balto-Slavic (2021)

With negative indefinite pronouns the Balto-Slavic languages all exhibit strict negative concord. In this study we investigate how negative concord functions in a context in which a connective negator (‘neither ... nor’) combines either phrases or clauses. We show that there are various types of non-concordant patterns.
Green Synthesis of Cr3+ Doped CaIn2O4-Carbon Hybrid Nanostructure and Its Light Absorption and Emission Properties (2019)

In this research article, we have used a novel route for synthesis of a greenish phosphor C-CaIn₂O₄ doped with Cr<sup>3+</sup> ions using green plant (aloe vera gel) and measured its light absorption and emission properties. Our main aim was to enhance the light absorption and emission properties of undoped C-CaIn₂O₄ in order to widen its applications. The introduction of CrO₃ ions can produce Cr ion defects that favor charge balance in Cr<sup>3+</sup>:C-CaIn₂O₄ to facilitate its photoluminescence. The effect of doping in core-shell nanostructure can effectively transfer energy from charge-transfer absorption band of optical host material to characteristic transition of Cr<sup>3+</sup> ions, utilizing more energy from host absorption for the photoluminescence of Cr<sup>3+</sup> ions. As-prepared Cr<sup>3+</sup>:C-CaIn₂O₄ exhibits two bands at 270 nm and 370 nm, which are shifted to at 265 and 370 nm when it is annealed at higher dosage of Cr<sup>3+</sup> ions. These are the ligand-to-metal O<sup>2-</sup> to Cr<sup>3+</sup> charge transfer bands. The light-emission is studied in analyzing migration, transfer and recombination processes of light-induced <i>e</i><sup>-</sup>-<i>h</i><sup>+</sup> pairs. The results are described in correlation to a Cr<sup>3+</sup>:C-CaIn₂O₄ core-shell nanostructure.
