An End to End Framework to High Performance Geometry-Aware Multi-Scale Keypoint Detection and Matching in Fisheye Imag (2019)

This paper addresses the problem of robust feature detection and matching across different views of the same scene taken using two (or more) wide angle cameras, assuming that their intrinsic calibration parameters are approximately known. We introduce an end-to-end framework with an aim to enhance both precision and recall in the matching process, i.e. increase the number of correct matches across the fisheye images while reducing the number of false positive matches. Experimental results demonstrate the effectiveness of the proposed work.

An Architectural Design Selection Tool Based on Design Tactics, Scenarios and Nonfunctional Requirements (2006)

This paper discusses a method and its supporting tool to select the software architecture for a family of software systems (commonly known as architectural styles) that meets the needs of the user. Our approach emphasizes the importance of basing architecture on non-functional requirements (NFRs). To this end, we have utilized a scenario-based approach that will determine NFRs of software architecture. NFRs are then mapped to optimal software architecture of a system by a set of table. Tables are applied to properly bridge the gap between NFRs and its corresponding software architecture.
One- or Two-Electron Water Oxidation, Hydroxyl Radical, or H2O2 Evolution (2017)

Electrochemical or photoelectrochemcial oxidation of water to form hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) or hydroxyl radicals (<sup>•</sup>OH) offers a very attractive route to water disinfection, and the first process could be the basis for a clean way to produce hydrogen peroxide. A major obstacle in the development of effective catalysts for these reactions is that the electrocatalyst must suppress the thermodynamically favored four-electron pathway leading to O<sub>2</sub> evolution. We develop a thermochemical picture of the catalyst properties that determine selectivity toward the one, two, and four electron processes leading to <sup>•</sup>OH, H<sub>2</sub>O<sub>2</sub>, and O<sub>2</sub>.
Algorithm for CSG aware scheduling in LTE systems (2019)

Long Term Evolution (LTE) technology aims for high data rate transmission in the order of several hundreds of Mbps. LTE standard delivers variety of Quality of Service (QoS) options, which enable to provide multiple services to the User Equipment (UE). Small cells are the miniature version of base stations, which are being deployed in public and private areas to provide uninterrupted connectivity to the UEs. In such deployment scenarios, the major requirement is to prioritize the users in Closed Subscriber Group (CSG) for providing the better QoS. The scheduler allocates the Resource Blocks (RB) to the selected UEs based on their QoS requirements. A novel scheduling algorithm is proposed in this paper for prioritizing CSG users having Non-Guaranteed Bit Rate (N-GBR) bearers to have better data rate connectivity. In the proposed scheme, the logic for selection of UEs in a TTI and allocation of RBs are varied based on the CSG weight index. Real time results reveal that the proposed scheme provides the significant performance gain in terms of fairness among CSG users for different channel conditions.
Modulation by Heparin of the Interaction of the A1 Domain of von Willebrand Factor With Glycoprotein Ib (1999)

The conformation of the A1 domain of von Willebrand factor (vWF) is a critical determinant of its interaction with the glycoprotein (GP) Ib/V/IX complex. To better define the regulatory mechanisms of vWF A1 domain binding to the GPIb/V/IX complex, we studied vWF-dependent aggregation properties of a cell line overexpressing the GPIb, GPIbβ, and GPIX subunits (CHO-GPIbβ/IX cells). We found that CHO-GPIbβ/IX cell aggregation required the presence of both soluble vWF and ristocetin. Ristocetin-induced CHO-GPIbβ/IX cell aggregation was completely inhibited by the recombinant VCL fragment of vWF that contains the A1 domain. Surprisingly, the substitution of heparin for ristocetin resulted in the formation of CHO-GPIbβ/IX cell aggregates. Using monoclonal antibodies blocking vWF interaction with GPIb/V/IX or mocarhagin, a venom metalloproteinase that removes the amino-terminal fragment of GPIb extending from aa 1 to 282, we demonstrated that both ristocetin- and heparin-induced aggregations involved an interaction between the A1 domain of vWF and the GPIb subunit of the GPIb/V/IX complex. The involvement of heparin in cell aggregation was also demonstrated after treatment of heparin with heparinase that abolished CHO-GPIbβ/IX cell aggregation. These results indicated that heparin was able to induce vWF-dependent CHO-GPIbβ/IX cell aggregation. In conclusion, we demonstrated that heparin is capable of positively modulating the vWF interaction with the GPIb/V/IX complex.
Effect of Anaerobic Soil Disinfestation and Mustard Seed Meal for Control of Charcoal Rot in California Strawberries (2016)

Anaerobic soil disinfestation (ASD) and mustard seed meal (MSM) appear to be promising non-fumigant alternatives for soilborne pathogens control. However, studies of their effect on charcoal rot caused by Macrophomina phaseolina in California strawberry are limited. A demonstration field trial with ASD with rice bran 20 t ha–1 (ASD-RB), MSM 4.5 t ha–1 (MSM), and ASD with rice bran 6.7 t ha–1 + MSM 4.5 t ha–1 (ASD-RB+MSM) treatments was conducted in a M. phaseolina-infested organic field in Oxnard, CA. A doubling of fruit yields relative to the grower standard, and a reduction in plant mortality by M. phaseolina, was achieved by ASD-RB. MSM failed to control M. phaseolina and resulted in fruit yields that were more than 20% below the ASD-RB yield. Fruit yield in the ASD-RB+MSM plot was intermediate between ASD-RB and MSM. Treatment effects on soil pH, EC, inorganic N dynamics, and soil microbial communities were also examined.

Imaging in advanced heart failure (2016)

Abstract Imaging techniques play an indispensable role in the management of patients presenting with advanced heart failure. From underlying etiopathological mechanisms to the severity and nature of heart failure, imaging provides a plethora of information that is not only critical to decision-making but also has prognostic significance, guiding therapeutic decisions in these patients relating to medical therapy, surgery, and device therapy. This chapter details the use of echocardiography, cardiac magnetic resonance imaging, and nuclear imaging with discussion of techniques, intercardiac pressures, and use in a range of cardiac conditions.
Determinants of fluoroscopy time for invasive coronary angiography and percutaneous coronary intervention: Insights from the NCDR® (2013)

Fluoroscopy times vary widely during ICA and PCI with operator and hospital-level factors contributing substantially to these differences. A better understanding of potentially modifiable sources of this variation will elucidate opportunities for enhancing the radiation safety of these procedures.
Cost Optimization of Water Recovery Systems for Steam Injected Gas Turbines (2002)

Steam injection in gas turbines has been used for many years to increase the power output as well as the efficiency of the system and, more recently, to reduce the formation of NOx during the combustion. The major drawback in steam-injected gas turbine technology is the need of large amounts of fresh water that is eventually lost into the atmosphere along with the exhaust gases. Nowadays, fresh water is not readily available in many places due to either local water shortages or environmental legislation that protects water sources from depletion and pollution. In order to deal with water constraints, water recovery systems (WRS) to recuperate the injected steam from the exhaust gases and return it to the steam injection system can be implemented. In this project, computer models for two different WRS configurations have been developed and tested. The computer models allow finding the optimum size, power requirements and capital costs of the heat exchangers involved in a particular WRS configuration. The models can also simulate the performance of WRS during a given period of time, calculating the energy consumed by fans and pumps in the process. This paper explains the details of the computer models and illustrates, as an example, the results obtained when both WRS configurations are applied to the GE LM2500 gas turbine. These results support the technical and economic feasibility of steam recovery for medium-size steam-injected gas turbines.
Proceedings -- US Russian workshop on fuel cell technologies (1996)

On September 26--28, 1995, Sandia National Laboratories sponsored the first Joint US/Russian Workshop on Fuel Cell Technology at the Marriott Hotel in Albuquerque, New Mexico. This workshop brought together the US and Russian fuel cell communities as represented by users, producers, R and D establishments and government agencies. Customer needs and potential markets in both countries were discussed to establish a customer focus for the workshop. Parallel technical sessions defined research needs and opportunities for collaboration to advance fuel cell technology. A desired outcome of the workshop was the formation of a Russian/American Fuel Cell Consortium to advance fuel cell technology for application in emerging markets in both countries. This consortium is envisioned to involve industry and national labs in both countries. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.
A diazo-based dry film for determination of total bilirubin in serum. (1983)

We have prepared a diazo-based dry film for use in determining total serum bilirubin. On a transparent support are a buffered gelatin layer containing a polymeric quaternary amine (the mordant) and a white, reflective spreading layer that contains all of the components necessary for detection of bilirubin. The method is based on the use of dyphylline and Triton X-100 surfactant to dissociate bilirubin from albumin and subsequent reaction of bilirubin with a diazonium salt [4-(N-carboxymethylsulfamyl)benzenediazonium hexafluorophosphate]. In the dry film, unconjugated, mono- and diconjugated, and strongly protein-linked (delta) bilirubin all react with the diazonium salt to produce azo dyes having absorption maxima at about 520 nm. With reflection densitometry and appropriate mathematical transformation, readings and bilirubin concentrations are linearly related to 260 mg/L. Results correlate well with those by the Jendrassik-Grof (Doumas modification) method (slope 0.994, intercept 1.1, correlation coefficient 0.993, Sy X x 4.0), and the method is precise (CV = 10.0% at Cav = 4.1 mg/L, 2.7% at Cav = 24.5 mg/L, 1.2% at Cav = 102 mg/L for patients' samples) and relatively free of interferences.
ENIGMA: a testbed for MPLS and QoS integration on IP networks (2006)

ENIGMA is a network configuration and management environment that provides end to end QoS (quality of service) across an MPLS transport network for UMTS services. As a result, a new concept of transport network is defined, which links the new trends in IP with the operator's needs. This solution will allow an improvement in the mobile user experience thanks to QoS and traffic engineering provisioning. This paper describes the project and explores the state of the art of the technology. It also introduces how the management software works and finishes with a testbed proposal and results
Modular aspect-oriented design with XPIs (2010)

The emergence of aspect-oriented programming (AOP) languages has provided software designers with new mechanisms and strategies for decomposing programs into modules and composing modules into systems. What we do not yet fully understand is how best to use such mechanisms consistent with common modularization objectives such as the comprehensibility of programming code, its parallel development, dependability, and ease of change. The main contribution of this work is a new form of information-hiding interface for AOP that we call the crosscut programming interface, or XPI. XPIs abstract crosscutting behaviors and make these abstractions explicit. XPIs can be used, albeit with limited enforcement of interface rules, with existing AOP languages, such as AspectJ. To evaluate our notion of XPIs, we have applied our XPI-based design methodology to a medium-sized network overlay application called Hypercast. A qualitative and quantitative analysis of existing AO design methods and XPI-based design method shows that our approach produces improvements in program comprehensibility, in opportunities for parallel development, and in the ease when code can be developed and changed.
Efficient seismic forward modeling using simultaneous random sources and sparsity (2010)

Abstract The high cost of simulating densely sampled seismic forward modeling data arises from activating sources one at a time in sequence. To increase efficiency, one could leverage recent innovations in seismic field-data acquisition and activate several (e.g., 2–6) sources simultaneously during modeling. However, such approaches would suffer from degraded data quality because of the interference between the model's responses to the simultaneous sources. Two new efficient simultaneous-source modeling approaches are proposed that rely on the novel tandem use of randomness and sparsity to construct almost noise-free model response to individual sources. In each approach, the first step is to measure the model's cumulative response with all sources activated simultaneously using randomly scaled band-limited impulses or continuous band-limited random-noise waveforms. In the second step, the model response to each individual sourceis estimated from the cumulative receiver measurement by exploiting knowledge of the random source waveforms and the sparsity of the model response to individual sources in a known transform domain (e.g., curvelet domain). The efficiency achievable by the approaches is primarily governed by the sparsity of the model response. By invoking results from the field of compressive sensing, theoretical bounds are provided that assert that the approaches would need less modeling time for sparser (i.e., simpler or more structured) model responses. A simulated modeling example is illustrated that shows that data collected with as many as 8192 sources activated simultaneously can be separated into the 8192 individual source gathers with data quality comparable to that obtained when the sources were activated sequentially. The proposed approaches could also dramatically improve seismic field-data acquisition efficiency if the source signatures actually probing the earth can be measured accurately.
Effects of Phosphodiesterase Type 5 Inhibition on Systemic and Pulmonary Hemodynamics and Ventricular Function in Patients With Severe Symptomatic Aortic Stenosis (2012)

This study shows for the first time that a single dose of a phosphodiesterase type 5 inhibitor is safe and well tolerated in patients with severe aortic stenosis and is associated with improvements in pulmonary and systemic hemodynamics resulting in biventricular unloading. These findings support the need for longer-term studies to evaluate the role of phosphodiesterase type 5 inhibition as adjunctive medical therapy in patients with aortic stenosis.
Enhanced Secrecy Rate Maximization for Directional Modulation Networks via IRS (2020)

Intelligent reflecting surface (IRS) is of low-cost and energy-efficiency and will be a promising technology for the future wireless communications like sixth generation. To address the problem of conventional directional modulation (DM) that Alice only transmits single confidential bit stream (CBS) to Bob with multiple antennas in a line-of-sight channel, IRS is proposed to create friendly multipaths for DM such that two CBSs can be transmitted from Alice to Bob. This will significantly enhance the secrecy rate (SR) of DM. To maximize the SR (Max-SR), a general non-convex optimization problem is formulated with the unit-modulus constraint of IRS phase-shift matrix (PSM), and the general alternating iterative (GAI) algorithm is proposed to jointly obtain the transmit beamforming vectors (TBVs) and PSM by alternately optimizing one and fixing another. To reduce its high complexity, a low-complexity iterative algorithm for Max-SR is proposed by placing the constraint of null-space (NS) on the TBVs, called NS projection (NSP). Here, each CBS is transmitted separately in the NSs of other CBS and AN channels. Simulation results show that the SRs of the proposed GAI and NSP can approximately double that of IRS-based DM with single CBS for massive IRS in the high signal-to-noise ratio region.

Revisión a largo plazo de fusión lumbar con técnica de Albee. (1999)

Summary. We present a long term retrospective study of 4 patients who were treated by vertebral fusion with Albee's technique. The etiology was vertebral fracture in 2 cases and scoliosis in 2 cases. All patients returned to their previous acti­ vity level. Follow-up assessment was done at a mean of 35 years. At this time, two patients developed spinal stenosis, one a pseudoarthrosi s of the cortical bone graft and one showed degenerative disease with back pain. Three cases required a second surgical treatment. Spinal fusion with the Albee's method allows anterior elasticity that could be responsible of vertebral space narrowing and a spinal stenosis. This elasticity also allows a better relief of local symptoms as compared to more rigid techniques.
Noncanonical Notch Signaling Modulates Cytokine Responses of Dendritic Cells to Inflammatory Stimuli (2012)

Dendritic cell (DC)-derived cytokines play a key role in specifying adaptive immune responses tailored to the type of pathogen encountered and the local tissue environment. However, little is known about how DCs perceive the local environment. We investigated whether endogenous Notch signaling could affect DC responses to pathogenic stimuli. We demonstrate that concurrent Notch and TLR stimulation results in a unique cytokine profile in mouse bone-marrow derived DCs characterized by enhanced IL-10 and IL-2, and reduced IL-12 expression compared with TLR ligation alone. Unexpectedly, modulation of cytokine production occurred through a noncanonical Notch signaling pathway, independent of γ-secretase activity. Modulation required de novo protein synthesis, and PI3K, JNK, and ERK activity were necessary for enhanced IL-2 expression, whereas modulation of IL-10 required only PI3K activity. Further, we show that this γ-secretase-independent Notch pathway can induce PI3K activity. In contrast, expression of the canonical Notch target gene Hes1 was suppressed in DCs stimulated with Notch and TLR ligands simultaneously. Thus, our data suggest that Notch acts as an endogenous signal that modulates cytokine expression of DCs through a noncanonical pathway and therefore has the potential to tailor the subsequent adaptive immune response in a tissue- and/or stage-dependent manner.
A viral assembly factor promotes AAV2 capsid formation in the nucleolus (2010)

The volume available in icosahedral virus capsids limits the size of viral genomes. To overcome this limitation, viruses have evolved strategies to increase their coding capacity by using more than one ORF while keeping the genome length constant. The assembly of virus capsids requires the coordinated interaction of a large number of subunits to generate a highly ordered structure in which the viral genome can be enclosed. To understand this process, it is essential to know which viral and nonviral components are involved in the assembly reaction. Here, we show that the adeno-associated virus (AAV) encodes a protein required for capsid formation by means of a nested, alternative ORF of the cap gene. Translation is initiated at a nonconventional translation start site, resulting in the expression of a protein with a calculated molecular weight of 23 kDa. This protein, designated assembly-activating protein (AAP), is localized in the host cell nucleolus, where AAV capsid morphogenesis occurs. AAP targets newly synthesized capsid proteins to this organelle and in addition fulfils a function in the assembly reaction itself. Sequence analysis suggests that also all other species of the genus Dependovirus encode a homologous protein in their cap gene. The arrangement of different ORFs that encode capsid proteins and an assembly factor within the same mRNA facilitates a timely coordinated expression of the components involved in the assembly process.
Near-infrared spectroscopy for soil water determination in small soil volumes (2004)

Critical soil water levels for soil microscale processes are difficult to determine because of variability in large soil volumes and lack of techniques for logging soil water contents in small soil volumes. This study tested nearinfrared (NIR) spectroscopy for soil water content determination. Five soil horizons with a range in soil texture, soil organic carbon, carbonates, pH and horizon depth, were tested at air-dry, field capacity and 0.1 MPa tension water content. Volumetric soil water content, determined using the standard method of oven-drying and soil bulk density, was compared to NIR absorbance in various combinations and wavelengths. The NIR spectra obtained with the probe in direct contact with the soil gave better results than when the probe was separated from the soil with a glass slide. The most reliable validation results were obtained using a multivariate partial least squares regression of the full spectrum with an r 2 of 0.95 and RMSE of prediction of 6.4%. Smoothing and derivatives of the spectra did not improve the validation results. The relationships for absorbance at single wavelength segments, ratios, differences and area under the curve around the 1940 nm peak were good (r 2 values near 0.85 ) but poorer than the results using the full spectra. The high correlation coefficients obtained with the wide variety of soils utilized in this study suggest that NIR absorbance is a practical method for determining volumetric soil water content for small soil volumes.
