Quality-of-information aware networking for tactical military networks (2011)

In tactical military networks, decisions must often be made quickly based on information at hand. It is a challenge to provide decision makers with a notion of the quality of the information they have, or to provide a method by which decision makers can specify a required quality of information. It is a further challenge to honor requests for a required quality of information when selecting information sources, transporting information through a highly-dynamic network, and perhaps performing processing on that information. In this paper we motivate the need for a general, but formal, definition of quality-of-information so that this metric may be specified and potentially optimized by algorithms that operate a tactical network. Furthermore, we define a new notion, the operational information content capacity, to capture the amount and quality of information that a network can deliver.
A Sinus Floor Reaugmentation Technique Around an Apically Exposed Implant Into the Maxillary Sinus (2019)

Sinus floor augmentation (SFA) is the most predictable treatment option in the atrophic posterior maxilla. However, exposure of the apical implant body into the maxillary sinus cavity is an occasionally observed phenomenon after SFA. Although most penetrating dental implants remain completely asymptomatic, they may induce recurrent rhinosinusitis or implant loss. Removal of the implant should be considered if there is significant implant exposure that results in prolonged treatment and increased costs. This case report demonstrates a recovery approach using sinus floor reaugmentation without implant removal in a patient with an apically exposed implant into the maxillary sinus cavity.

Aqueous Stream Characterization from Biomass Fast Pyrolysis and Catalytic Fast Pyrolysis (2016)

Biomass pyrolysis offers a promising means to rapidly depolymerize lignocellulosic biomass for subsequent catalytic upgrading to renewable fuels. Substantial efforts are currently ongoing to optimize pyrolysis processes including various fast pyrolysis and catalytic fast pyrolysis schemes. In all cases, complex aqueous streams are generated containing solubilized organic compounds that are not converted to target fuels or chemicals and are often slated for wastewater treatment, in turn creating an economic burden on the biorefinery. Valorization of the species in these aqueous streams, however, offers significant potential for substantially improving the economics and sustainability of thermochemical biorefineries. To that end, here we provide a thorough characterization of the aqueous streams from four pilot-scale pyrolysis processes: namely, from fast pyrolysis, fast pyrolysis with downstream fractionation, in situ catalytic fast pyrolysis, and ex situ catalytic fast pyrolysis. These configurations and processes represent characteristic pyrolysis processes undergoing intense development currently. Using a comprehensive suite of aqueous-compatible analytical techniques, we quantitatively characterize between 12 g kg–1 of organic carbon of a highly aqueous catalytic fast pyrolysis stream and up to 315 g kg–1 of organic carbon present in the fast pyrolysis aqueous streams. In all cases, the analysis ranges between 75 and 100% of mass closure. The composition and stream properties closely match the nature of pyrolysis processes, with high contents of carbohydrate-derived compounds in the fast pyrolysis aqueous phase, high acid content in nearly all streams, and mostly recalcitrant phenolics in the heavily deoxygenated ex situ catalytic fast pyrolysis stream. Overall, this work provides a detailed compositional analysis of aqueous streams from leading thermochemical processes—analyses that are critical for subsequent development of selective valorization strategies for these waste streams.
A CMOS Temperature Sensor With a Voltage-Calibrated Inaccuracy of $\pm$0.15$ ^{\circ}$C (3$\sigma$) From $-$55$^{\circ}$C to 125$^{\circ}$C (2012)

This paper describes the design of a low power, energy-efficient CMOS smart temperature sensor intended for RFID temperature sensing. The BJT-based sensor employs an energy- efficient 2nd-order zoom ADC, which combines a coarse 5-bit SAR conversion with a fine 10-bit ΔΣ conversion. Moreover, a new integration scheme is proposed that halves the conversion time, while requiring no extra supply current. To meet the stringent cost constraints on RFID tags, a fast voltage calibration technique is used, which can be carried out in only 200 msec. After batch calibration and an individual room-temperature calibration, the sensor achieves an inaccuracy of ±0.15°C (3σ) from -55°C to 125°C . Over the same range, devices from a second lot achieved an inaccuracy of ±0.25°C (3σ) in both ceramic and plastic packages. The sensor occupies 0.08 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in a 0.16 μm CMOS process, draws 3.4 μA from a 1.5 V to 2 V supply, and achieves a resolution of 20 mK in a conversion time of 5.3 msec. This corresponds to a minimum energy dissipation of 27 nJ per conversion.
Nanochannels for Supramolecular Organisation of Dyes (2007)

The supramolecular organisation of molecules, complexes or clusters is a fruitful concept for the design of systems exhibiting specific macroscopic properties. The encapsulation of guest species into the pores or channels of host materials presents a challenging approach to the preparation of novel chemical and optical materials. Zeolite L has been shown to be an ideal host for the supramolecular organisation of organic dyes. A new hierarchy of structural ordering can be achieved by either arranging the zeolite L crystals into densely packed, oriented monolayers or by interfacing them to the environment via molecules bound to the edges of the crystals. These concepts are reviewed here, as well as some potential applications.

Electrochemical Techniques, Introduction (2012)

Abstract Modern electrochemistry provides both a synthetic methodology to the materials scientist and an analytical tool for the evaluation of compositions and the kinetics of charge transfer processes. On the one hand, a variety of bulk materials and functional surfaces are prepared electrochemically. Historically this includes the electrorefining of materials such as aluminum, gold, and copper; surface preparation as illustrated in the anodization of aluminum, the electroetching of semiconductors, and the electroplating of thick metallic films. Similarly, the electrosynthesis of soft materials, for example, conducting organic polymers is an important route in select cases. More recently, the electrosynthesis of quantum structures either by direct deposition as in the case of ultra‐thin film layered metal structures, or by electroetching as exemplified in the synthesis of porous silicon has become an important application of electrochemistry. On the other hand, electroanalytical chemistry has been developed as an extremely sensitive physical characterization technique for the quantification of conducting and semiconducting surfaces and interfaces. The corrosion properties/processes of metallic surfaces and semiconductor electronic properties are two key areas where electrochemical characterization has had high impact. In keeping with the central analytical theme of this work, this chapter details the class of electrochemical techniques specifically aimed at characterizing materials and their interfaces.
Efficient LED light distribution cavities using low loss, angle-selective interference transflectors (2009)

Recent advances in solid state light source efficiency and luminance present the technical challenge of distributing light from very small point sources to large areas, with area distribution ratios having orders of magnitude greater than previously addressed. Broad adoption of LEDs in lighting and liquid crystal displays is in part contingent on addressing this fundamental light distribution issue. Here we present new materials based on giant birefringent nanotechnology which address these deficiencies allowing us to guide light in air via a novel light distribution system. Resulting from controlled in-plane and out-of-plane x,y,z refractive indices of adjacent layers, these multilayer interference films possess both angle selective and polarization selective reflectance. The angle selectivity can be tuned in both azimuth and polar angle, relieving a key constraint of prior materials. Our work has been done on a physically large scale enabling demonstration of large light management systems of industrial and practical relevance.
Highly Stable SrZrO3 Bipolar Resistive Switching Memory by Ti Modulation Layer (2010)

In this paper, the resistive switching characteristic of the SrZrO 3 (SZO)-based resistance random access memory (RRAM) composed of Pt/Ti/SZO/LaNiO 3 (LNO) are investigated. The electrical testing results show that the device has lower operation voltage, lower compliance current, long retention behavior, and stable resistance ratio over 10 4 s under 0.3 V reading voltage. It is demonstrated that the active metal Ti as an oxygen getter can modify the resistive switching property of the SZO based RRAM. After depositing all stack films, the post annealing (PA) treatment with various conditions was carried out to form the interfacial layer (TiO x ) between Ti and SZO. By using X-ray Photoelectron Spectrometer (XPS) analysis, the Ti layer as an oxygen getter is confirmed. The better SZO based RRAM device can be made with the proper TiO x film formed by suitable annealing temperature and thickness of Ti layer.
miR-218 Directs a Wnt Signaling Circuit to Promote Differentiation of Osteoblasts and Osteomimicry of (2012)

miR-218 may be a universal stimulator of Wnt-signaling during bone development and cancer progression.MicroRNAs (miRNAs) negatively and post-transcription-ally regulate expression of multiple target genes to supportanabolic pathways for bone formation. Here, we show thatmiR-218isinducedduringosteoblastdifferentiationandhaspotent osteogenic properties. miR-218 promotes commit-ment and differentiation of bone marrow stromal cells byactivating a positive Wnt signaling loop. In a feed forwardmechanism, miR-218 stimulates the Wnt pathway by down-regulating three Wnt signaling inhibitors during the processof osteogenesis: Sclerostin (SOST), Dickkopf2 (DKK2), andsecreted frizzled-related protein2 (SFRP2). In turn, miR-218expressionisup-regulatedinresponsetostimulatedWntsig-nalingandfunctionallydrivesWnt-relatedtranscriptionandosteoblast differentiation, thereby creating a positive feed-back loop. Furthermore, in metastatic breast cancer cells butnot in normal mammary epithelial cells, miR-218 enhancesWnt activity and abnormal expression of osteoblastic genes(osteomimicry)thatcontributetohomingandgrowthofcellsmetastatic to bone. Thus, miR-218/Wnt signaling circuitamplifies both the osteoblast phenotype and osteomimicry-related tumor activity.
Tuning Properties of Avian and Frog Bitter Taste Receptors Dynamically Fit Gene Repertoire sizes (2014)

Bitter taste perception in vertebrates relies on a variable number of bitter taste receptor (Tas2r) genes, ranging from only three functional genes in chicken to as many as approximately 50 in frogs. Humans possess a medium-sized Tas2r repertoire encoding three broadly and several narrowly tuned receptors plus receptors with intermediate tuning properties. Such tuning information is not available for bitter taste receptors of other vertebrate species. In particular it is not known, whether a small Tas2r repertoire may be compensated for by broad tuning of these receptors, and on the other side, whether a large repertoire might entail a preponderance of narrowly tuned receptors. To elucidate this question, we cloned all three chicken Tas2rs, the two turkey Tas2rs, three zebra finch Tas2rs, and six Tas2rs of the Western clawed frog representative of major branches of the phylogenetic tree, and screened them with 46 different bitter compounds. All chicken and turkey Tas2rs were broadly tuned, the zebra finch Tas2rs were narrowly tuned, and frog Tas2rs ranged from broadly to narrowly tuned receptors. We conclude that a low number of functional Tas2r genes does not imply a reduced importance of bitter taste per se, as it can be compensated by large tuning width. A high number of functional Tas2r genes appears to allow the evolution of specialized receptors, possibly for toxins with species-specific relevance. In sum, we show that variability in tuning breadth, overlapping agonist profiles, and staggered effective agonist concentration ranges are shared features of human and other vertebrate Tas2rs.
The spectrum efficiency of a base station antenna array system for spatially selective transmission (1995)

In this paper we investigate the spectrum efficiency gain using transmitting antenna arrays at the base stations of a mobile cellular network. The proposed system estimates the angular positions of the mobiles from the received data, and allows multiple mobiles to be allocated to the same channel within a cell. This is possible by applying a transmit scheme which directs nulls against co-channel users within the cell. It is shown that multiple mobiles per cell is an efficient way of increasing capacity in comparison with reduced channel reuse distance and narrow beams (without directed nulls). The effect of the spatial spread angle of the locally scattered rays in the vicinity of the mobile is also investigated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Data from Proteasome Inhibition Potentiates Antitumor Effects of Photodynamic Therapy in Mice through Induction of Endoplasmic Reticulum Stress and Unfolded Protein Response (2023)

&lt;div&gt;Abstract&lt;p&gt;Photodynamic therapy (PDT) is an approved therapeutic procedure that exerts cytotoxic activity toward tumor cells by inducing production of reactive oxygen species such as singlet oxygen. PDT leads to oxidative damage of cellular macromolecules, including proteins that undergo multiple modifications such as fragmentation, cross-linking, and carbonylation that result in protein unfolding and aggregation. Because the major mechanism for elimination of carbonylated proteins is their degradation by proteasomes, we hypothesized that a combination of PDT with proteasome inhibitors might lead to accumulation of carbonylated proteins in endoplasmic reticulum (ER), aggravated ER stress, and potentiated cytotoxicity toward tumor cells. We observed that Photofrin-mediated PDT leads to robust carbonylation of cellular proteins and induction of unfolded protein response. Pretreatment of tumor cells with three different proteasome inhibitors, including bortezomib, MG132, and PSI, gave increased accumulation of carbonylated and ubiquitinated proteins in PDT-treated cells. Proteasome inhibitors effectively sensitized tumor cells of murine (EMT6 and C-26) as well as human (HeLa) origin to PDT-mediated cytotoxicity. Significant retardation of tumor growth with 60% to 100% complete responses was observed &lt;i&gt;in vivo&lt;/i&gt; in two different murine tumor models (EMT6 and C-26) when PDT was combined with either bortezomib or PSI. Altogether, these observations indicate that combination of PDT with proteasome inhibitors leads to potentiated antitumor effects. The results of these studies are of immediate clinical application because bortezomib is a clinically approved drug that undergoes extensive clinical evaluations for the treatment of solid tumors.

Delay Line Optical Recognizer Based on Coherent-To-Chaotic Light Conversion (2000)

We demonstrate a delay line optical recognizer at 2.5 Gbit/s. Recognition is based on a coherent-to-chaotic light conversion followed by a fiber array correlation filter. Experimental evidence shows performance improvement in comparison with a classical scheme as far as phase noise is concerned. An experimental characterization of the recognizer is reported. Methods for improving the recognition error probability are suggested.

Direct Anterior Approach Using Navigation Improves Accuracy of Cup Position Compared to Conventional Posterior Approach (2017)

The accuracy of cup position in total hip arthroplasty is essential for a satisfactory result as malpositioning increases the risk of complications including dislocation, high wear rate, loosening, squeaking, edge loading, impingement and ultimately failure. We studied 166 patients in a single-surgeon-series of matched cohorts of patients who underwent total hip arthroplasties. Four separate groups were identified comprising of the posterior approach +/- navigation and the direct anterior approach +/- navigation. We found a significant difference between the direct anterior navigated group and the posterior non-navigated group for both anteversions (P < 0.05, confidence interval (CI) -3.86 to -1.73) and inclination (P < 0.05, CI -3.08 to -1.08). Almost, 72% of anterior navigated patients fell within 5<sup>o</sup> of the navigation software set target cup position of 45<sup>o</sup> inclination and 20<sup>o</sup> anteversion and 100% were within 10<sup>o</sup>. Only 30% of posterior non-navigated were within 5<sup>o</sup> of both anteversion and inclination and 73% were within 10<sup>o</sup>. There was also a significant difference between the direct anterior navigated and non-navigated group with respect to anteversion only (p < 0.05, CI 1.50 to 1.30). There were no other significant differences between approaches +/- navigation. The direct anterior approach allows ease of access to both anterior-superior iliac spines for navigation and a supine patient allows anteversion and inclination to be measured in the frontal plane. We conclude that the direct anterior approach with navigation improves the accuracy of cup position compared to the conventional posterior approach without navigation.

Dynamic Behavior Analysis in Compressed Fingerprint Videos (2004)

Traditional fingerprint acquisition is limited to single-image capture and processing. With the advent of faster capture hardware, faster processors, and advances in video compression standards, newer systems can capture and exploit video signals for tasks that are difficult using a single image. We propose the use of fingerprint video sequences to investigate detecting two aspects of the dynamic behavior of fingerprints. Specifically, we are interested in the detection of distortion of fingerprint impressions due to excessive force and the detection of the positioning of fingers during image capture. These issues often lead to difficulties in establishing a precise match between acquired images. The proposed techniques investigate dynamic characteristics of fingerprints across video sequence frames. A significant advantage of our approach for distortion analysis is that it works directly on MPEG-1,-2 encoded fingerprint video bitstreams. The proposed methods have been tested on the NIST-24 live-scan fingerprint video database and the results are promising. We also describe a new concept called the "resultant biometrics", a new type of biometrics which has both a physiological, physical (e.g., force, torque, linear motion, rotation) component and/or a temporal characteristic, added by a subject to an existing biometric. This resultant biometric is both desirable and efficient in terms of easy modification of compromised biometrics and is harder to produce with spoof body parts.
