Feasibility Analysis of a Vortex Generator for Absorption Heat Pumps (1996)

Abstract Significant thermal resources in the form of low temperature industrial waste heat, between 211 to 528 trillion kJ (200 and 500 trillion BTU’s) per annum, have the potential to drive absorption heat pumps. The proposed vortex generator permits a practical heat pump to operate efficiently with as much as 20 to 30°C below the boiling temperature of water (70–80°C (158–176°F)). Energy flows and auxiliary power requirements are computed. The system is shown to operate with relatively low temperature waste heat with higher specific capacity than conventional systems.

Ischemic cholangiopathy following liver transplantation from donation after cardiac death donors (2008)

The use of donation after cardiac death (DCD) donor hepatic allografts is becoming more widespread; however, there have been published reports of increased graft failure from specific complications associated with this type of allograft. The complication of ischemic cholangiopathy (IC) has been reported to occur more frequently after the use of DCD hepatic allografts. We report the results of 52 liver transplants from DCD donors and the factors that influenced the development of IC. We conducted a retrospective review of all DCD and donation after brain death (DBD) donor liver recipients from September 2003 through December 2006 at a single institution. Survival and complication rates were compared between the 2 groups. The Cox proportional hazards model was then used to identify recipient and donor factors that predict the development of IC in the DCD group. There was no difference in 1-year patient or graft survival rates between the 2 groups. There was no incidence of primary nonfunction from the DCD allografts. Hepatic artery complications and anastomotic bile duct complications were comparable in the 2 groups. There was, however, an increased risk for the development of IC in the DCD group (13.7% versus 1%, P = 0.001). Donor weight >100 kg and total ischemia times > or =9 hours, in donors older than 50 years of age, predicted the development of IC in the DCD group. In conclusion, there is a higher incidence of IC in recipients receiving DCD donor livers; however, patient and graft outcomes with DCD donors remain comparable to those with DBD donors. Careful donor selection may improve utilization of these grafts.
Analysis of Proteins by Immunoblotting (2021)

In immunoblotting (western blotting), proteins are first separated by SDS-PAGE and then transferred electrophoretically from the gel onto a support membrane that binds proteins tightly. After the unreacted binding sites of the membrane are blocked to suppress nonspecific adsorption of antibodies, the immobilized proteins are reacted with a specific polyclonal or monoclonal antibody. Antigen-antibody complexes are visualized using chromogenic, fluorescent, or chemiluminescent reactions. Immunoblotting protocols are reagent specific and, owing to the wide assortment of equipment, reagents, and antibodies available, highly diverse. Presented here is an example of a workable protocol for developing a blot using horseradish peroxidase (HRP)-conjugated secondary antibody and enhanced chemiluminescence (ECL). ECL is based on the emission of light during the HRP-catalyzed oxidation of luminal or other substrates. Emitted light is captured on film or by a CCD camera, for qualitative or semiquantitative analysis. Because ECL is so sensitive, it has become a popular detection method. This protocol can be modified for different membranes, antibodies, and detection systems. Optimal dilutions of the primary and secondary antibodies need to be determined empirically, but recommendations provided by the manufacturer are usually a good starting point.
Foliated Quantum Error-Correcting Codes (2016)

We show how to construct a large class of quantum error-correcting codes, known as Calderbank-Steane-Shor codes, from highly entangled cluster states. This becomes a primitive in a protocol that foliates a series of such cluster states into a much larger cluster state, implementing foliated quantum error correction. We exemplify this construction with several familiar quantum error-correction codes and propose a generic method for decoding foliated codes. We numerically evaluate the error-correction performance of a family of finite-rate Calderbank-Steane-Shor codes known as turbo codes, finding that they perform well over moderate depth foliations. Foliated codes have applications for quantum repeaters and fault-tolerant measurement-based quantum computation.

Quantitative proteomic analysis of proteins and post‐translational modifications during the metaphase to anaphase transition after altered O‐GlcNAcylation (2012)

Post‐translational modifications (PTMs) are essential in regulating the function, stability, and localization of proteins. One such modification is the O‐GlcNAc. O‐GlcNAc is the attachment of a single N‐acetylglucosamine moiety to serine and threonine residues on nuclear and cytoplasmic proteins. The modification is dynamically processed on proteins by the enzymes O‐GlcNAc transferase (O‐GlcNAc addition) or O‐GlcNAcase (O‐GlcNAc removal). Our objective is to explore how alterations in O‐GlcNAcylation alter several different types of PTM's during mitosis. We employed SILAC (Stable Isotope Labeling of Amino Acids in Cell culture) labeling to quantitate differences in cells with either an O‐GlcNAc transferase or O‐GlcNAcase gain of function. These samples were combined, digested, and fractionated to enrich for O‐GlcNAc, phosphate, acetyl, or ubiquitinated peptides. By mass spectrometry analysis, we have identified numerous proteins and PTMs altered by aberrant O‐GlcNAcylation. Multiple bioinformatic and systems biology tools has allowed a comprehensive analysis of the interplay between multiple post‐translational modifications providing valuable insight into how these modifications control cellular functions such as mitotic progression.

Self-Glycolipids Modulate Dendritic Cells Changing the Cytokine Profiles of Committed Autoreactive T Cells (2012)

The impact of glycolipids of non-mammalian origin on autoimmune inflammation has become widely recognized. Here we report that the naturally occurring mammalian glycolipids, sulfatide and β-GalCer, affect the differentiation and the quality of antigen presentation by monocyte-derived dendritic cells (DCs). In response to sulfatide and β-GalCer, monocytes develop into immature DCs with higher expression of HLA-DR and CD86 but lower expression of CD80, CD40 and CD1a and lower production of IL-12 compared to non-modulated DCs. Self-glycolipid-modulated DCs responded to lipopolysaccharide (LPS) by changing phenotype but preserved low IL-12 production. Sulfatide, in particular, reduced the capacity of DCs to stimulate autoreactive Glutamic Acid Decarboxylase (GAD65) - specific T cell response and promoted IL-10 production by the GAD65-specific clone. Since sulfatide and β-GalCer induced toll-like receptor (TLR)-mediated signaling, we hypothesize that self-glycolipids deliver a (tolerogenic) polarizing signal to differentiating DCs, facilitating the maintenance of self-tolerance under proinflammatory conditions.
Environmental Injustice in the Urban Southwest: A Case Study of Phoenix, Arizona (2013)

This chapter examines the distribution of technological hazards in the Phoenix metropolitan area, focusing on race and class inequalities in facility locations and the issue of environmental justice. To examine potential environmental justice concerns, the readers address two questions in what follows. The study area captures an expanding zone of hazardous land uses: from the original core in South Phoenix, it has extended with post-WWII industrial development east into Sky Harbor airport and west into older suburban areas. In metropolitan Phoenix, 1% of residentially zoned areas directly border industrial zoning, in contrast to the 35% of neighborhoods in the study area which do so. The presence of the minority population in South Phoenix was considered an investment “hazard,” leading to bank redlining, perpetuating economic underdevelopment, and inadequate housing in Black and Latino neighborhoods. As Harvey notes, in cities today, &quot;concerns for environmental justice, are kept strictly subservient to concerns for economic efficiency, continuous growth, and capital accumulation&quot;.
The Age-Related Perfusion Pattern Measured With Arterial Spin Labeling MRI in Healthy Subjects (2018)

<b>Aim:</b> To analyze age-related cerebral blood flow (CBF) using arterial spin labeling (ASL) MRI in healthy subjects with multivariate principal component analysis (PCA). <b>Methods:</b> 50 healthy subjects (mean age 45.8 ± 18.5 years, range 21-85) had 3D structural MRI and pseudo-continuous ASL MRI at resting state. The relationship between CBF and age was examined with voxel-based univariate analysis using multiple regression and two-sample <i>t</i>-test (median age 41.8 years as a cut-off). An age-related CBF pattern was identified using multivariate PCA. <b>Results:</b> Age correlated negatively with CBF especially anteriorly and in the cerebellum. After adjusting by global value, CBF was relatively decreased with aging in certain regions and relatively increased in others. The age-related CBF pattern showed relative reductions in frontal and parietal areas and cerebellum, and covarying increases in temporal and occipital areas. Subject scores of this pattern correlated negatively with age (<i>R</i><sup>2</sup> = 0.588; <i>P</i> < 0.001) and discriminated between the older and younger subgroups (<i>P</i> < 0.001). <b>Conclusion:</b> A distinct age-related CBF pattern can be identified with multivariate PCA using ASL MRI.
High-Btu gas via in-situ coal gasification. [Review of Hoe Creek experiments] (1978)

Underground coal gasification offers a relatively low cost, environmentally sound method to produce SNG from coal. The resource is huge and widely distributed. The results of recent underground coal gasification tests in the U.S. have been very encouraging. A brief review of the technology is given followed by a description of Lawrence Livermore Laboratory's recent underground coal gasification experiment, Hoe Creek No. 2, in which gas of 100 to 150 Btu/scf was produced using air injection, and 250 to 300 Btu/scf when injecting steam and oxygen. Plans for future experiments are also described.
Self-Organizing Tissue-Engineered Constructs in Collagen Hydrogels (2012)

A novel self-organizing behavior of cellularized gels composed of collagen type 1 that may have utility for tissue engineering is described. Depending on the starting geometry of the tissue culture well, toroidal rings of cells or hollow spheroids were prompted to form autonomously when cells were seeded onto the top of gels and the gels released from attachment to the culture well 12 to 24 h after seeding. Cells within toroids assumed distinct patterns of alignment not seen in control gels in which cells had been mixed in. In control gels, cells formed complex three-dimensional arrangements and assumed relatively higher levels of heterogeneity in expression of the fibronectin splice variant ED-A--a marker of epithelial mesenchymal transformation. The tissue-like constructs resulting from this novel self-organizing behavior may have uses in wound healing and regenerative medicine, as well as building blocks for the iterative assembly of synthetic biological structures.
Medium access control of wireless LANs for mobile computing (1994)

To provide high-speed seamless services for mobile computing, an effective medium access control capable of dealing with mobility issues in multicell wireless local area networks is needed. The physical layers discussed include direct sequence spread spectrum (DS-SS), frequency hopped spread spectrum (FH-SS), and diffuse infrared. Both spread spectrum transmissions are in the 2.4 to 2.4835 GHz ISM band, according to FCC part 15.247.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Spectroscopic Estimation of Biomass in Canopy Components of Paddy Rice Using Dry Matter and Chlorophyll Indices (2017)

Crop biomass is a critical variable for characterizing crop growth development, understanding dry matter partitioning, and predicting grain yield. Previous studies on the spectroscopic estimation of crop biomass focused on the use of various spectral indices based on chlorophyll absorption features and found that they often became saturated at high biomass levels. Given that crop biomass is commonly expressed as the dry weight of canopy components per unit ground area, it may be better estimated using the spectral indices that directly characterize dry matter absorption. This study aims to evaluate a group of four dry matter indices (DMIs) by comparison with a group of four chlorophyll indices (CIs) for estimating the biomass of individual components (e.g., leaves, stems) and their combinations with the field data collected from a two-year rice cultivation experiment. The Red-edge Chlorophyll Index (CIRed-edge) of the CI group exhibited the best relationship with leaf biomass (R2 = 0.82) for the whole growing season and with total biomass (R2 = 0.81), but only for the growth stages before heading. However, the Normalized Difference Index for Leaf Mass per Area (NDLMA) of the DMI group showed the best relationships with both stem biomass (R2 = 0.81) and total biomass (R2 = 0.81) for the whole season. This research demonstrated the suitability of dry matter indices and provided physical explanations for the superior performance of dry matter indices over chlorophyll indices for the estimation of whole-season total biomass.
TGF-Beta Signaling Manipulation as Potential Therapy for IBD (2013)

Crohn’s disease (CD) and ulcerative colitis (UC), two chronic and relapsing inflammatory bowel diseases (IBD), are supposed to develop in genetically-predisposed individuals as a result of an excessive immune mucosal response directed against normal components of the gut microbiota. There is also evidence that defects in counter-regulatory mechanisms play a major role in the pathogenesis of IBD. One such a defect involves TGF-β1, a cytokine produced by multiple cells types and able to inhibit pathogenic responses in the gut. In both CD and UC, TGF-β1 is highly produced but unable to signal through the TGF-β receptor-associated Smad pathway and suppress production of inflammatory molecules. Abrogation of TGF-β1 activity has been related to Smad7, an intracellular protein that binds to TGF-β receptor and inhibits TGF-β1-driven Smad-dependent signalling. Indeed, silencing of Smad7 with a specific antisense oligonucleotide restores TGF-β1/Smad signalling, thereby down-regulating inflammatory cytokine production and ameliorating experimental colitis in mice. Altogether these observations led to the development of an oral pharmaceutical compound containing the specific Smad7 antisense oligonucleotide (herein termed GED0301), which seems to be safe and well tolerated in CD patients. In this article we summarize the data supporting the pathogenic role of Smad7 in IBD and discuss the recent results of the use of GED0301 in CD. Keywords: Smad7, colitis, antisense oligonucleotide, Crohn’s disease, ulcerative colitis.

Parathyroid Hormone: Effects of the 3-34 Fragment in Vivo and Vitro (1983)

The biologically active fragment ofparathyroid hormone, consisting of residues 1-34, and its in vitro antagonist, fragment 3-34, were administered separately or in combination to chronically thyroparathyroidectomized dogs. These fragments were also studied in vitro with dog renal cortical membranes. Fragment 3-34 inhibited the stimulation of adenylate cyclase by fragment 1-34 in vitro, but had no agonist or antagonistic effects on renal phosphate transport in vivo.
Estimation of Viable Spores in Bacillus atrophaeus (BG) Particles of 1 to 9 μm Size Range (2008)

Abstract This study examined the viable organism content in a bioaerosol disseminated from a letter contaminated with Bacillus atrophaeus (BG) (anthrax simulant). In addition to using nutrient medium based slit samplers to sample the bioaerosol in the air space where the dispersion occurred, the individual who opened the contaminated letter was also used as a bioaerosol sampler by incorporating an external filter trap positioned over the inlet of the respirator filter canister worn by the individual. The reasons for this latter approach should be clear: it would provide actual quantitative information on the inhalation exposure hazard to an individual faced with this scenario. Where bioaerosol particles may be comprised of aggregates of many smaller particles, organism viability within the aggregate is important and may have an impact on the current definition of ‘infectious dose’ or ‘lethal dose’. Both terms assume single organism counts. Results from two different methods of measuring aerosols due to opening contaminated letters are presented: slit samplers and glass microfibre filter medium placed on the inlet port of a respirator cartridge. The total number of viable bioaerosol particles measured at the inhalation port of the filter canister was 40 times greater than measured by the slit samplers. Accordingly, this may be accounted for by a distribution of bioaerosol particles comprised of aggregates of single BG spores. A model has been proposed that estimates the number of individual viable spores in a distribution of aerosol particles through a relatively simple probability density function distribution for particle size, and which incorporates realistic assumptions regarding particle diameters, packing density and spore viability.
Locking Carbon Nanotubes in Confined Lattice Geometries − A Route to Low Percolation in Conducting Composites (2011)

A significant reduction in the electrical percolation threshold is achieved by locking carbon nanotubes (CNTs) in a predominantly hexagonally close-packed (HCP) colloidal crystal lattice of partially plasticized latex particles. Contrary to other widely used latex processing where CNTs are randomly distributed within the latex matrix, for the first time, we show that excluding CNTs from occupying the interior volume of the latex particles promotes the formation of a nonrandom segregated network. The electrical percolation threshold is four times lower in an ordered segregated network made with colloidal particles near their glass transition temperature (T(g)) in comparison to in a random network made with particles at a temperature well above the T(g). This method allows for a highly reproducible way to fabricate robust, stretchable, and electrically conducting thin films with significantly improved transparency and lattice percolation at a very low CNT inclusion which may find applications in flexible and stretchable electronics as well as other stretchable technologies. For instance, our technology is particularly apt for touch screen applications, where one needs homogeneous distribution of the conductive filler throughout the matrix.
Detection of Nitric Oxide by the Sample Analysis at Mars (SAM) Instrument Implications for the Presence of Nitrates (2014)

One of the main goals of the Mars Science Laboratory is to determine whether the planet ever had environmental conditions able to support microbial life. Nitrogen is a fundamental element for life, and is present in structural (e.g., proteins), catalytic (e.g., enzymes and ribozymes), energy transfer (e.g., ATP) and information storage (RNA and DNA) biomolecules. Planetary models suggest that molecular nitrogen was abundant in the early Martian atmosphere, but was rapidly lost to space by photochemistry, sputtering impact erosion, and oxidized and deposited to the surface as nitrate. Nitrates are a fundamental source for nitrogen to terrestrial microorganisms. Therefore, the detection of nitrates in soils and rocks is important to assess the habitability of a Martian environment. SAM is capable of detecting nitrates by their thermal decomposition into nitric oxide, NO. Here we analyze the release of NO from soils and rocks examined by the SAM instrument at Gale crater, and discuss its origin.
Corner target positioning with unknown walls' positions (2019)

Here we consider a corner target positioning problem under the condition of unknown walls' positions using time‐division multiple‐input‐multiple‐output (MIMO) radar. Firstly, we propose an estimation algorithm for the walls' positions using the Back‐Projection (BP) imaging algorithm. Then, after obtaining the BP image of target, we extract the focus regions produced by different multipaths. Finally, we obtain the position of the target based on the extracted walls' positions and the focus regions. Simulations and experiments results validate the proposed algorithm.
Reliability of spin-to-charge conversion measurements in graphene-based lateral spin valves (2021)

Abstract Understanding spin physics in graphene is crucial for developing future two-dimensional spintronic devices. Recent studies show that efficient spin-to-charge conversions (SCCs) via either the inverse spin Hall effect or the inverse Rashba–Edelstein effect (IREE) can be achieved in graphene by proximity with an adjacent spin–orbit coupling (SOC) material. Lateral spin valve devices, made up of a graphene Hall bar and ferromagnets, are best suited for such studies. Here, we report that signals mimicking the IREE can be measured in pristine graphene possessing negligible SOC, confirming that these signals are unrelated to SCC. We identify either the anomalous Hall effect in the ferromagnet or the ordinary Hall effect in graphene induced by stray fields as the possible sources of this artefact. By quantitatively comparing these options with finite-element-method simulations, we conclude the latter better explains our results. Our study deepens the understanding of SCC measurement schemes in graphene, which should be taken into account when designing future experiments.
Photonic nanofences: Combining the advantages of photonic nanowires and slot waveguides (2015)

Subwavelength photonic nanofences are able to guide light with intense evanescent fields, up to above 90% of the coupled light, and with low losses (~12 dB/mm). This presents them as ideal candidates for sensing applications.
