On Limits of Antenna Packing in Low Power Systems (2004)

We evaluate spectral efficiency limits of low power portable communication devices which are only constrained by fixed transceiver aperture G IR 3 for mounting antennas.A new notion of antenna-space capacity of G naturally emerges from analysis of the achievable spectral efficiency.Antenna-space capacity measures the maximum growth of spectral efficiency that antenna configuration can achieve, given arbitrary number of antennas.Thus, the notion of antenna-space capacity also has a practical utility as a benchmark for design of actual antenna configurations.As a concrete example, we compute the antenna-space capacity of a circular geometry, where antennas can only be placed on the circumference of a circle.We show that uniform antenna placement on the circle is suboptimal antenna configuration for any fixed number of antennas, but comes arbitrarily close to optimum as the number of antennas grows unboundedly.
Heterogeneous additive‐free highly selective synthesis of 2,5‐bis(hydroxymethyl)furan over catalysts with ultra‐low Pt content (2021)

Abstract Ultra‐low‐loaded supported Pt catalysts showed an extremely high activity in selective hydrogenation of bioavailable 5‐hydroxymethylfurfural (5‐HMF) to the corresponding diol, i.e. 2,5‐bis(hydroxymethyl)furan (BHMF); among the synthesized catalysts with a Pt content varying in the range 0.025–0.25 wt%, the most active one appeared to be the sample 0.1% Pt/CeO 2 –ZrO 2 , which allows us to obtain BHMF with a 97% yield and 100% selectivity from 5‐HMF without the use of alkali or any other additives at a temperature of 170 °C and H 2 pressure of 1 MPa, with the 5‐HMF:Pt ratio higher than 1000 mol mol –1 . © 2021 Society of Chemical Industry (SCI).
Space station propulsion (1987)

Two propulsion systems have been selected for the space station: gaseous H/O rockets for high thrust applications and the multipropellant resistojets for low thrust needs. These two thruster systems integrate very well with the fluid systems on the space station, utilizing waste fluids as their source of propellant. The H/O rocket will be fueled by electrolyzed water and the resistojets will use waste gases collected from the environmental control system and the various laboratories. The results are presented of experimental efforts with H/O and resistojet thrusters to determine their performance and life capability, as well as results of studies to determine the availability of water and waste gases.
Broad tuning of whispering-gallery modes in silicon microdisks (2010)

Silicon microdisks with dynamically-tunable resonance spectra are achieved with nanoscale, in-plane silicon electrical contacts in a single lithographic step. Electrical current is passed through the devices to enable thermal tuning via joule heating. A 14nm wavelength shift is demonstrated with 1.6mW power consumption in devices with >20nm free spectral ranges and quality factors exceeding 20,000. Spectral shifts equal to a full width at half maximum can be achieved with approximately 10microW tuning power for a mode with quality factor of 20,000.
Novel ways of depositing ZnTe films by a solution growth technique. Final subcontract report, 1 January 1990--1 January 1992 (1992)

An electrochemical process has been successfully developed for the reproducible deposition of ZnTe and copper-doped ZnTe films suitable as transparent ohmic contacts for CdS/CdTe solar cells. The development of this method and optimization of key processing steps in the fabrication of CdS/CdTe/ZnTe:Cu devices has allowed IEC to achieve cell performance results of FF>70% and {eta} {approximately}10%. Preliminary efforts have indicated that the deposition methods investigated are potentially feasible for the formation of other II-VI compounds for use in polycrystalline thin film solar devices and should be the focus of future work.
Application of native T1 mapping for distinguishing histopathologic subtypes, grades, and stages of rectal adenocarcinoma (2023)

This study evaluated the clinical significance of using native T1 mapping for distinguishing histopathologic subtypes, grades, and stage of rectal adenocarcinoma by measuring parameters such as T1 relaxation time and apparent diffusion coefficient (ADC). The results showed that T1 and ADC values were significantly higher in rectal mucinous adenocarcinoma (MC) compared to non-mucinous rectal adenocarcinoma (AC). In the AC group, T1 values were significantly lower in the low-grade AC than in the high-grade AC. Our findings suggest that native T1 mapping can distinguish histopathologic subtypes of renal adenocarcinoma. Moreover, T1 values distinguish different grades of AC more accurately than ADC values.
Miniature switchable wideband notch antenna for multistandard wireless terminals (2012)

A miniature wideband switchable notch antenna was designed for wireless multistandard terminals. The antenna, a quarter-wavelength notch antenna, integrates at its open end a PIN-diode switched capacitor to create two selectable bands at 880-960 MHz (GSM-900) and 1710-3200 MHz (DCS-1800, IMT-2000, LTE, WiFi-802.11b/g/n). It features a small size of λ/14 at the lowest frequency (880 MHz) and covers both bands with a VSWR <; 3:1 and an efficiency between 50% and 85%.
Synthesis of 3′-Amino-3′-Deoxyguanosine and 3′-Amino-3′-Deoxyxyloguanosine Monophosphate Hepdirect Prodrugs from Guanosine (2009)

The synthesis of 3'-amino-3'-deoxyguanosine and 3'-amino-3'-deoxyxyloguanosine monophosphate HepDirect prodrugs from guanosine is reported. Initial incorporation of N,N-dibenzylformamidino protection of the C2-amino of guanosine masked the reactivity of that group and simplified purification of subsequent analogues. The first key intermediate, 9-(2,5-bis-O-tert-butyldimethylsilyl-beta-D-ribofuranosyl)-2-N-(N,N-dibenzylformamidino)guanine (3a), was prepared in 60% yield after recycling of the undesired 3',5'-bis-O-protected byproduct (4a) by simple equilibration in methanol to a mixture of the two bis-O-protected compounds. Thus, protected, the 3'-position was manipulated to form the 3'-deoxyribo- or 3'-deoxyxylo-3'-azido derivatives (9 or 16, respectively). Further selective manipulations provided the cis-5'-monophosphate (3-chlorophenyl)-1,3-propanyl diester prodrugs (HepDirect prodrugs), 15 and 21. These HepDirect prodrugs were demonstrated to activate to their respective NTPs in rat hepatocytes.
Clinician Corner- A Simple and Efficient Modified Goshgarian Arch (“T” Arch) Appliance for Correcting Single Tooth Scissor Bite (2017)

Scissor bite is a rare form of malocclusion that is often accompanied by varying degrees of facial asymmetry. Correction and treatment of scissor bite in posterior teeth is a challenging job for an orthodontist. There are several treatment options for correction of scissor bite in posterior teeth but some have their own ill-effects on the dentition thus contributing further to the problem and some require patient compliance which compromises the outcome of the treatment. Therefore to overcome these drawbacks we have designed a new appliance to correct the molar scissor bite.
Reaction Mechanism of Deoxydehydration by Ceria-Supported Monomeric Rhenium Catalysts: A Computational Study (2022)

The detailed structures of monomeric ReOx catalysts supported on the CeO2 surface and the reaction mechanism of the deoxydehydration (DODH) reaction were investigated by density functional theory calculations. After examining various ReOxHy structures over CeO2 without substrate adsorption, the stable structure under the experimental condition at 400 K was determined to be the ReVIIO2 species. The reaction mechanism of DODH was then investigated for the conversion of 1,4-anhydroerythritol to 2,5-dihydrofuran as a model reaction. Through the investigations of several reaction pathways, an oxygen vacancy-assisted mechanism, in which the starting structure is the ReIVO species and the oxidation state of the Re atom changes between +IV and +VI during the reaction, was postulated to be the most plausible pathway, considering the energies of the intermediates and the barrier height for the cleavage of the two C–O bonds.
Tu1487 Progressive Occlusion of Mesenteric Artery Changes Biomagnetic Signature of Intestinal Slow Wave (2012)

G A A b st ra ct s research. Oral domperidone has been reported in some cases to prolong the QT interval and predispose to ventricular arrhythmias (Reddymasu et al. Am J Gastro 2007;102:20362045). The aims: 1) To establish an indications and clinical profile of patients receiving domperidone through the limited access protocol 2) to investigate possible side effects of domperidone 3) to analyze ECG reports and the duration of QT intervals. Methods: Study involved a retrospective chart review of 163 patients referred to a single physician at the tertiary GI Motility Center. Patients demographics, GI diagnosis, cardiovascular complain and ECG tracings were obtained. Prolonged QTc were verified if they were longer than 470 ms in females and longer than 450 ms in male patients. Results: Overall 23 out of 163 (13%) patients (15 F; mean age 47, range 18-73) presenting with chief complaints of nausea and vomiting were enrolled in FDA approved protocol and received doses of domperidone ranging from 10 to 30mg QID for at least 6 up to 12 months. 8 (36%) patients were Hispanic, 12 (52%) Caucasian, and 3(12%) African American. A total 16 (60%) of these patients (9F) were diagnosed with GP, 4 females met the criteria for Cyclic Vomiting Syndrome and 3 patients had symptoms of unexplained nausea. 6 (27%) ECG reports showed non-significant sinus arrhythmias, and one male patient had an irregular rhythm. Women had mean heart rates of 82 (range 52-112) and men's average HR was 86 (range 55-105) bpm. Overall the mean value of QTc for all domperidone patients was 427 ms (ranges 383 507 ms). Further analysis of ECGs for females showed, mean QTc duration of 425 (394-507) ms and in males it was 429 (383-469) ms. Two patients (9%), one of each gender, had QTc prolongation above the normal respected value. No patients complained about palpitation or cardiac/ chest pain. Two patients noticed breast discomfort. No other potential adverse events including extra-pyramidal side effects were reported during this investigation. Conclusions:1) Domperidone is legally available in USA under the FDAIND approved protocol and can be prescribed for patients with symptoms of nausea and vomiting related to gastroparesis and other motility disorders 2) No clinically relevant cardiac complaints and ECG changes including QTc prolongations were discovered during this observation 3) Domperidone can be regarded as a safe prokinetic and antiemetic agent.
Gene expression associated with white syndromes in a reef building coral, Acropora hyacinthus. (2014)

Background Corals are capable of launching diverse immune defenses at the site of direct contact with pathogens, but the molecular mechanisms of this activity and the colony-wide effects of such stressors remain poorly understood. Here we compared gene expression profiles in eight healthy Acropora hyacinthus colonies against eight colonies exhibiting tissue loss commonly associated with white syndromes, all collected from a natural reef environment near Palau. Two types of tissues were sampled from diseased corals: visibly affected and apparently healthy. Results Tag-based RNA-Seq followed by weighted gene co-expression network analysis identified groups of co-regulated differentially expressed genes between all health states (disease lesion, apparently healthy tissues of diseased colonies, and fully healthy). Differences between healthy and diseased tissues indicate activation of several innate immunity and tissue repair pathways accompanied by reduced calcification and the switch towards metabolic reliance on stored lipids. Unaffected parts of diseased colonies, although displaying a trend towards these changes, were not significantly different from fully healthy samples. Still, network analysis identified a group of genes, suggestive of altered immunity state, that were specifically up-regulated in unaffected parts of diseased colonies. Conclusions Similarity of fully healthy samples to apparently healthy parts of diseased colonies indicates that systemic effects of white syndromes on A. hyacinthus are weak, which implies that the coral colony is largely able to sustain its physiological performance despite disease. The genes specifically up-regulated in unaffected parts of diseased colonies, instead of being the consequence of disease, might be related to the originally higher susceptibility of these colonies to naturally occurring white syndromes.
Biofunctionalized Calcium Phosphate Cement to Enhance the Attachment and Osteodifferentiation of Stem Cells Released from Fast-Degradable Alginate-Fibrin Microbeads (2012)

Stem cell-encapsulating microbeads could be mixed into a paste such as calcium phosphate cement (CPC), where the microbeads could protect the cells from the mixing and injection forces. After being placed, the microbeads could quickly degrade to release the cells throughout the scaffold, while creating macropores. The objectives of this study were to (1) construct alginate-fibrin microbeads encapsulating human umbilical cord mesenchymal stem cells (hUCMSCs) embedded in the surface of novel biofunctionalized CPC and (2) investigate microbead degradation, cell release, and osteodifferentiation on CPC. Hydrogel microbeads were fabricated that encapsulated hUCMSCs at 1×106 cells/mL. CPC was biofunctionalized with fibronectin (Fn) and Arg-Gly-Asp (RGD). Four scaffolds were tested: CPC control, CPC mixed with Fn, CPC mixed with RGD, and CPC grafted with RGD. The degradable microbeads released hUCMSCs at 7 days, which attached to CPC. Adding Fn or RGD to CPC greatly improved cell attachment. CPC grafted with RGD showed the fastest cell proliferation, with cell density being ninefold that on CPC control. The released hUCMSCs underwent osteodifferentiation. Alkaline phosphatase, osteocalcin, collagen 1, and runt-related transcription factor 2 (Runx2) gene expression increased by 10 to 30 fold at 7–21 days, compared with day 1. The released cells on CPC synthesized bone minerals, with the mineralization amount at 21 days being two orders of magnitude higher than that at 7 days. In conclusion, alginate-fibrin microbeads embedded in CPC surface were able to quickly release the hUCMSCs that attached to biofunctionalized CPC. Incorporating Fn and RGD into CPC greatly improved cell function, and CPC grafted with RGD had the fastest cell proliferation. The released cells on CPC differentiated into the osteogenic lineage and synthesized bone minerals. The new biofunctionalized CPC with hUCMSC-encapsulating microbeads is promising for bone regeneration applications.
Rheology Analysis of Thermosetting Resin Candidates for Use in Fuel Compacting (2012)

The AGR-1 and AGR-2 overcoating and compacting method utilized a wet mixing process where liquid resin (Hexion Durite SC-1008) was blended with natural and synthetic graphite to produce a graphite/resin matrix for overcoating. The matrix production method specified in the scale-up plan is a co-grinding jet mill process where powdered resin and graphite are fed at the same time into a jet mill. Because of the change in matrix production style, SC-1008 cannot be used in the jet milling process because it is a liquid. Also, attempts to dry out matrix made with SC-1008 for use in the overcoating process at B&W had mixed results. The SC-1008 resin became tacky when dried which caused the matrix to build up inside the overcoater. The scale- up jet milling/mixing and overcoating processes required that a suite of solid or powdered resins be identified. Suitable resins candidates were down selected to two resins, specifically Plenco 14838 and Hexion SD-1708. These resins are referred to as novolac or “two-stage” resins because they require the addition of a curing agent such as hexamethylenetetramine (Hexa) to promote an increased level of cross linking. The overcoating matrix is made of 3 components; natural graphite, synthetic graphite, and resin. The most influential component of the compacting process is the resin component and how it behaves with regards to time, temperature, and pressure. The selected scale-up resins are considered fast curing which means that the increase in molecular weight (curing) occurs over a relatively short period of time, ranging from a few seconds to several minutes depending on the temperature. To find the optimal compacting conditions it is useful to quantify this behavior. In this report, rheology is used to investigate viscosity as a function of time at specific temperatures for the previously mentioned resins.

System for reducing combustion dynamics and NO.sub.x in a combustor (2023)

A combustor includes an end cap that extends radially across at least a portion of the combustor. The end cap includes an upstream surface axially separated from a downstream surface. A plurality of tubes extend from the upstream surface through the downstream surface of the end cap to provide fluid communication through the end cap. Each tube in a first set of the plurality of tubes has an inlet proximate to the upstream surface and an outlet downstream from the downstream surface. Each outlet has a first portion that extends a different axial distance from the inlet than a second portion.
Affinity purification of the tobacco plastid RNA polymerase and in vitro reconstitution of the holoenzyme (2004)

We affinity-purified the tobacco plastid-encoded plastid RNA polymerase (PEP) complex by the alpha subunit containing a C-terminal 12 x histidine tag using heparin and Ni(2+) chromatography. The composition of the complex was determined by mass spectrometry after separating the proteins of the >900 kDa complex in blue native and SDS polyacrylamide gels. The purified PEP contained the core alpha, beta, beta', beta" subunits and five major associated proteins of unknown function, but lacked sigma factors required for promoter recognition. The holoenzyme efficiently recognized a plastid psbA promoter when it was reconstituted from the purified PEP and recombinant plastid sigma factors. Reconstitution of a plastid holoenzyme with individual sigma factors will facilitate identification of sigma factor-specific promoter elements.

Generic deformable implicit mesh models for automated reconstruction (2003)

Deformable 3-D models can be represented either as explicit or implicit surfaces. Explicit surfaces, such as triangulations or wire-frame models, are widely accepted in the computer vision and computer graphics communities. However, for automated modeling purposes, they suffer from the fact that fitting to 2-D and 3-D image-data typically involves minimization of the Euclidean distance between observations and their closest facets, which is a non-differentiable distance function. By contrast, implicit surface representations allow fitting by minimizing an algebraic distance where one only needs to evaluate a differentiable field potential function at every data point. However, they have not gained wide acceptance because they are harder to meaningfully deform and render. To combine the strength of both approaches, we propose a method that can turn a completely arbitrary triangulated mesh, such as one taken from the Web, into an implicit surface that closely approximates its shape and can deform in tandem with it. This allows both graphics designers to deform and reshape the implicit surface by manipulating explicit surfaces using standard deformation techniques and automated fitting algorithms to take advantage of the attractive properties of implicit surfaces. We demonstrate the applicability of our technique for upper body-head, neck and shoulders-automated reconstruction.
The bones of the system (2016)

Large software organizations are transitioning to event data platforms as they culturally shift to better support data-driven decision making. This paper offers a case study at Microsoft during such a transition. Through qualitative interviews of 28 participants, and a quantitative survey of 1,823 respondents, we catalog a diverse set of activities that leverage event data sources, identify challenges in conducting these activities, and describe tensions that emerge in data-driven cultures as event data flow through these activities within the organization. We find that the use of event data span every job role in our interviews and survey, that different perspectives on event data create tensions between roles or teams, and that professionals report social and technical challenges across activities.
Energy Efficiency and Yield Optimization for Optical Interconnects via Transceiver Grouping (2020)

Optical interconnects enabled by silicon microring-based transceivers offer great potential for short-reach data communication in future high-performance computing systems. However, microring resonators are prone to process variations that harm both the energy efficiency and the yield of the fabricated transceivers. Especially in the application scenario where a batch of transceivers are fabricated for assembling multiple optical networks, how the transceivers are mixed and matched can directly impact the average energy efficiency and the yield of the networks assembled. In this study, we propose transceiver grouping for assembling communication networks from a pool of fabricated transceivers, aiming to optimize the network energy efficiency and the yield. We evaluated our grouping algorithms by wafer-scale measurement data of microring-based transceivers, as well as synthetic data generated based on an experimentally validated variation model. Our experimental results demonstrate that optimized grouping achieves significant improvement in the network energy efficiency and the yield across a wide range of network configurations, compared to a baseline strategy that randomly groups the transceivers.
