NMP ST8 Dependable Multiprocessor: Technology and Technology Validation Overview (2010)

†† is a major step toward NASA's long- held desire to take advantage of high-performance, Commercial-Off-The-Shelf (COTS) technology in onboard processing solutions for space applications. DM is a cluster of high performance COTS processors connected with a high speed interconnect and operating under the control of a radiation-hardened system controller and platform and technology-independent fault tolerant middleware. The platform and technology -independent middleware is DM technology. The development of DM technology represents a significant paradigm shift. For applications that only need to be radiation tolerant, DM technology allows t he user to fly ten to one hundred times the processing capability of current radiation hardened space systems. As a software-based and platform and technology-independent technology, DM enable space missions to employ current COTS devices as opposed to tec hnologies 2 or 3 generations behind the state - of-the-art. The DM project conducted its TRL6 Technology Validation in 2008 and 2009. This paper provides an overview of DM technology and a summary of the TRL6 technology validation effort. A companion paper, NMP ST8 Dependable Multiprocessor: Technology Validation Approach and Results, provides an overview of the technology validation approach and the DM model validation effort. DM was developed as one of four ST8 flight experiments. A significant effort went into the design and development of the DM flight experiment system. Although NASA eliminated the TRL7 flight experiments from the ST8 project, the DM flight experiment is also discussed in this pap er. This paper describes the original ST8 flight experiment flight configuration and an updated flight configuration which is not subject to the constraints of the original ST8 spacecraft. The paper also describes post -TRL6 technology developments including upgraded DM implementation with Open MPI, true open system HAM (High Availability Middleware), and enhanced intermittent fault detection capability. More details are provided in the DM TRL6 Technology Validation Report. ‡‡

Kinematic control and visual display of redundant teleoperators (2003)

A framework is proposed for helping the operator of a redundant teleoperator to perform tasks in a 3D environment. The aid is implemented on a graphics workstation. Kinematic control of the redundant teleoperator is performed by specifying end-effector trajectories and using a numerical inverse kinematic algorithm to determine positions of the intermediate links of the teleoperator. Also proposed are graphic displays that aid the operator in the execution of tasks. Experiments with a twelve-degrees-of-freedom vehicle manipulator system that were conducted to compare these suggestions with other methods of kinematic control and display indicate that the proposed framework results in superior performance by reducing both task completion times and collision with obstacles in the environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Inhalation of oxygen and carbon dioxide gas. Effect on composition of cerebral venous blood (1967)

INHALATION of either carbon dioxide gas mixtures or 100% oxygen are widely used therapeutically in cerebrovascular disease and conditions causing cerebral anoxia. There is little or no data in man concerning any improvement of oxygen available to the brain resulting from this treatment, although certain drugs are known to increase oxygen available to ischemic brain.<sup>1,2</sup> Techniques for monitoring cerebral blood, P<sub>o</sub><sub>2</sub>, P<sub>co</sub><sub>2</sub>, and pH now permit recording any changes in the composition of the cerebral venous blood during inhalation of oxygen and carbon dioxide gas mixtures.

Quantitative Analysis of Epstein‐Barr Virus (EBV)–Specific CD8+T Cells in Patients with Chronic Active EBV Infection (2004)

To clarify the pathogenesis of chronic active Epstein-Barr virus (EBV) infection, EBV-specific CD8+ T cells were enumerated, by use of human leukocyte antigen (HLA)-A*2402-restricted tetramers, in 8 patients with chronic active EBV infection, 10 patients with infectious mononucleosis, and 16 EBV-seropositive healthy control subjects. In most of the patients with chronic active EBV infection, EBV-specific CD8+ T cells were not detected. Of note, latent membrane protein 2-specific CD8+ T cells were not detectable in any patients with chronic active EBV infection. In contrast, EBV-specific CD8+ T cells were detected in patients with infectious mononucleosis and in healthy control subjects. Low frequencies of EBV-specific CD8+ T cells may be one of the immunological features of chronic active EBV infection.
Differential recovery of glycosaminoglycan after IL-1-induced degradation of bovine articular cartilage depends on degree of degradation (2003)

In the present study we examined cartilage matrix repair following IL-1-induced matrix depletion. Previous data indicated that, in some cases, chondrocytes can synthesize macromolecules to establish a functional extracellular matrix in response to a matrix-damaging insult or when placed in a three-dimensional environment with inadequate matrix. However, the conditions under which such 'repair' can occur are not entirely clear. Prior studies have shown that chondrocytes in trypsin-depleted young bovine articular cartilage can replenish tissue glycosaminoglycan (GAG) and that the rate of replenishment is relatively uniform throughout the tissue, suggesting that all chondrocytes have similar capacity for repair. In the present study we used the characteristic heterogeneous distribution of matrix depletion in response to IL-1 exposure in order to investigate whether the severity of depletion influenced the rate of GAG replenishment. We used the delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC) method to monitor the spatial and temporal evolution of tissue GAG concentration ([GAG]). For both mild (n=4) and moderate (n=10) IL-1-induced GAG depletion, we observed partial recovery of GAG (80% and 50% of baseline values, respectively) over a 3-week recovery period. During the first 2 weeks of recovery, [GAG] increased homogeneously at 10-15 mg/ml per week. However, during the third week the regions most severely depleted following IL-1 exposure showed negligible [GAG] accumulation, whereas those regions affected the least by IL-1 demonstrated the greatest accumulation. This finding could suggest that the most severely degraded regions do not recover fully, possibly because of more severe collagen damage; this possibility requires further examination.
Multiphase flow of immiscible fluids on unstructured moving meshes (2012)

In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex (DSC), that moves with the flow in a Lagrangian manner. Mesh optimization operations improve element quality and avoid element inversion. In the context of multiphase flow, we guarantee that every element is occupied by a single fluid and, consequently, the interface between fluids is represented by a set of faces in the simplicial complex. This approach ensures that the underlying discretization matches the physics and avoids the additional book-keeping required in grid-based methods where multiple fluids may occupy the same cell. Our Lagrangian approach naturally leads us to adopt a finite element approach to simulation, in contrast to the finite volume approaches adopted by a majority of fluid simulation techniques that use tetrahedral meshes. We characterize fluid simulation as an optimization problem allowing for full coupling of the pressure and velocity fields and the incorporation of a second-order surface energy. We introduce a preconditioner based on the diagonal Schur complement and solve our optimization on the GPU. We provide the results of parameter studies as well as a performance analysis of our method.
Vegetable fiber as reinforcing elements for cement based composite in housing applications – a Brazilian experience (2018)

Vegetable fibers are a hierarchical structure material in the macro, micro and nanometric scales that have been used as reinforcement in cementitious materials. In nanoscale, the nanofibrillated cellulose has the advantage of having good mechanical performance and high specific surface, which contributes to improve the adhesion between fiber and matrix. In hybrid reinforcement, with micro and nanofibers, nanofibrillated cellulose forms bonding with the matrix and acts as stress transfer bridges in the nano-cracking with corresponding strengthening of the cementitious composite. Processing has a strong influence on performance of the fiber cement composite. Two fabrication methods were evaluated: (i) slurry dewatering followed by pressing and (ii) extrusion. The extrusion process strongly depends on the rheological characteristics of the fresh cement material but it can better organize the microstructure of the fiber cement due to the partial orientation of the fibers in the extruder direction. Curing process also plays a key role in the performance of the final product. Accelerated carbonation at early age is a promising technology and a strategy to mitigate the durability problems with the composite materials; it decreases porosity, promotes a higher density in the interface guarantying a good fiber–matrix adhesion and a better mechanical behavior. Alternative MgO-SiO2 clinker free binder is also presented as a suitable alternative to cementitious products reinforced with cellulosic pulps. Finally, mechanical behavior of fiber cement under flexural loading is evaluated by modulus of rupture, fracture toughness, the initial crack growth resistance in cement matrix, and fracture energy that is obtained to evaluate the influence of toughening mechanisms promoted by fibers, such as pullout and bridging, on the mechanical performance of the composites. Degradation during the service life is also crucial for the evaluation of the durability of the resulting materials and components in real applications exposed to different environmental conditions as roofing, partitioning or ceiling elements. It can be concluded that more sustainable and high performance components based on engineered natural raw materials for civil construction can bring valuable contributions for the affordable housing in particular to developing region.
Linking of oligoesters hydrolysis to polyurethane coatings (2013)

Abstract The hydrolytic stability of a series of oligoesters comprised of three and four different monomers was evaluated. The hydroxyl terminal oligoesters were prepared from adipic acid (AA) and isophthalic acid (IPA), with six different diols and one triol, which included: 1,4‐butanediol, 1,5‐pentanediol, 1,6‐hexanediol, neopentyl glycol, 2‐methyl‐1,3‐propanediol, trimethylolpropane, and 2‐butene‐1,4‐diol. The hydroxyl terminated oligoesters were reacted with phenyl isocyanate to form telechelic urethane groups. Hydrolysis rate constants were obtained from plots of acid number vs. time. It was observed that ternary oligoester systems had lower hydrolysis rates than quaternary systems. In addition to investigating the hydrolytic stability of the synthesized oligoesters, polyurethane coatings were produced by reacting the hydroxyl‐terminated oligoesters with an aliphatic polyisocyanate (1,6‐hexanediisocyanate trimer). Model oliogester hydrolysis was then correlated to the weatherability of a crosslinked polyurethane film. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014 , 131 , 40198.
ANTERIOR CRUCIATE LIGAMENT RECONSRUCTION IN CHILDREN: OUTCOMES OF QUADRICEPS VERSUS HAMSTRING AUTOGRAFTS (2021)

Background: Emerging evidence has suggested reduced donor site pain and equivalent/improved functional outcomes in adults undergoing ACL reconstruction (ACLR) with quadriceps (QT) autograft versus hamstrings (HT) grafts. No studies in children comparing QT versus HT autografts have assessed postoperative strength or active range of motion (AROM) in addition to more commonly accepted patient-reported outcome measures (PROMs). Hypothesis/Purpose: The purpose of this study was to directly compare clinical and patient-reported outcomes of pediatric patients undergoing QT and HT autograft ACL reconstructions. We hypothesized that use of QT autografts would result in similar clinical and PROMs to HT autografts. Methods: A retrospective cohort analysis of pediatric patients (≤18 years) undergoing primary transphyseal ACLR from 1/2018-12/2019 without concomitant multiligamentous reconstruction was conducted. Outcomes at 3 and 6 months, including isokinetic strength testing, PROMIS and IKDC scores, and AROM were compared between patients receiving either HT or QT autografts. Hamstrings to quadriceps (H/Q) ratios were calculated using the ratio of the respective peak torque values normalized to body weight. Multiple imputation was utilized to minimize bias resulting from missed follow-up appointments. Results: 84 patients met inclusion criteria (Table 1). The 40 patients receiving QT were more often male (62.5% vs 34.1%, p=0.009). There were no differences in operative time (p=0.053) or proportion of patients requiring meniscus repair (p=0.958). At 3 months postoperative, those with HT had lower H/Q ratios (62.2 ± 15.8 vs 78.6 ± 19.9, p&lt;0.001) and limb symmetry index (LSI) in flexion (86.1 ± 17.1 vs 94.3 ± 17.6, p=0.042), while patients with QT had lower LSI in extension (66.8 ± 13.2 vs 77.3 ± 12.6, p=0.001). The H/Q ratio was also lower at 6 months among patients receiving HT (59.7 ± 11.2 vs 66.3 ± 8.2, p=0.004). IKDC, PROMIS physical function, and PROMIS pain interference scores were not different between cohorts at either 3 or 6 months. There was no difference in AROM in flexion or extension between groups at all postoperative visits. Patients with QT were more likely to have a postoperative wound issue (20.0% vs 2.3%, p=0.012). Conclusion: Significant differences in quadriceps and hamstrings strength at 3 months were observed for ACLR patients by graft type. This contributed to higher H/Q ratios at 3 and 6 months postoperatively for patients receiving QT. QT grafts appear to have a higher rate of postoperative infection/wound issues.

Hodgkin and Reed-Sternberg cell–associated autoantigen CLIP-170/restin is a marker for dendritic cells and is involved in the trafficking of macropinosomes to the cytoskeleton, supporting a function-based concept of Hodgkin and Reed-Sternberg cells (2002)

Little is known about the distribution in normal cells of CLIP-170, a linkage mediator between endocytic vesicles and microtubules, and restin, a splice variant encoded by the same gene and marker for Hodgkin and Reed-Sternberg (HRS) cells of Hodgkin disease. Although only trace amounts of CLIP-170/restin are present in peripheral blood mononuclear cell subpopulations, monocyte-derived dendritic cells (DCs) and interleukin-4 (IL-4) + CD40L-activated B cells express high levels of CLIP-170/restin. CLIP-170/restin colocalizes preferentially with membranes of intermediate macropinocytic vesicles, suggesting a new function of CLIP-170/restin in the trafficking of macropinosomes to the cytoskeleton, which is a crucial step in antigen presentation. The strong expression of CLIP-170/restin in HRS cells, DCs, and activated B cells underscores their functional similarities supporting a function-based concept of HRS cells as professional antigen-presenting cells.
Influence of Peripheral Visual Field Constriction on the Sense of Speed during Driving (2021)

In this study, we analyzed the human sense of speed with respect to changes in the field of view by presenting a partially hidden expressway driving image that was reproduced through virtual reality. The obtained results indicate that even if the visual field range is constant, there are varying tendencies of change that depend on conditions such as the driving speed and road environment. Furthermore, such tendencies are supported by human visual field characteristics and distance perception mechanisms. This suggests that analyzing the effects of intentional peripheral visual field constriction on the sense of speed can aid in achieving driving control that is based on information associated with human visual perception.

Super-resolution MIMO radar (2016)

A multiple input, multiple output (MIMO) radar emits probings signals with multiple transmit antennas and records the reflections from targets with multiple receive antennas. Estimating the relative angles, delays, and Doppler shifts from the received signals allows to determine the locations and velocities of the targets. Standard approaches to MIMO radar based on digital matched filtering or compressed sensing only resolve the angle-delay-Doppler triplets on a (1/(N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> ), 1/B, 1/T ) grid, where N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> and N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> are the number of transmit and receive antennas, B is the bandwidth of the probing signals, and T is the length of the time interval over which the reflections are observed. In this work, we show that the continuous angle-delay-Doppler triplets and the corresponding attenuation factors can be recovered perfectly by solving a convex optimization problem. This result holds provided that the angle-delay-Doppler triplets are separated either by 10/(N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> - 1) in angle, 10.01/B in delay, or 10.01/T in Doppler direction. Furthermore, this result is optimal (up to log factors) in the number of angle-delay-Doppler triplets that can be recovered.
Efficient K-Nearest Neighbor Graph Construction Using MapReduce for Large-Scale Data Sets (2014)

This paper presents an efficient method using Hadoop MapReduce for constructing a K-nearest neighbor graph (K-NNG) from a large-scale data set. K-NNG has been utilized as a data structure for data analysis techniques in various applications. If we are to apply the techniques to a large-scale data set, it is desirable that we develop an efficient K-NNG construction method. We focus on NN-Descent, which is a recently proposed method that efficiently constructs an approximate K-NNG. NN-Descent is implemented on a shared-memory system with OpenMP-based parallelization, and its extension for the Hadoop MapReduce framework is implied for a larger data set such that the shared-memory system is difficult to deal with. However, a simple extension for the Hadoop MapReduce framework is impractical since it requires extremely high system performance because of the high memory consumption and the low data transmission efficiency of MapReduce jobs. The proposed method relaxes the requirement by improving the MapReduce jobs, which employs an appropriate key-value pair format and an efficient sampling strategy. Experiments on large-scale data sets demonstrate that the proposed method both works efficiently and is scalable in terms of a data size, the number of machine nodes, and the graph structural parameter K.
A Cut Principle for Information Flow (2015)

We view a distributed system as a graph of active locations with unidirectional channels between them, through which they pass messages. In this context, the graph structure of a system constrains the propagation of information through it. Suppose a set of channels is a cut set between an information source and a potential sink. We prove that, if there is no disclosure from the source to the cut set, then there can be no disclosure to the sink. We introduce a new formalization of partial disclosure, called blur operators, and show that the same cut property is preserved for disclosure to within a blur operator. A related compositional principle ensures limited disclosure for a class of systems that differ only beyond the cut.
Functions and applications of monostable-bistable transition logic elements (MOBILE's) having multiple-input terminals (1994)

The MOBILE is a logic gate exploiting the monostable-bistable transition of a circuit that consists of two resonant tunneling transistors connected in series. It has several advantages including multiple inputs and multiple functions. This paper describes the output characteristics of multiple-input MOBILE's and discusses their applications. For a two-input MOBILE, it is demonstrated that both NAND and NOR operations are possible with the appropriate control voltage. This implies the possibility of a variable function logic gate. Furthermore, the threshold logic operations for a weighted sum of input signals are demonstrated for a three-input MOBILE with a weight ratio of 4:2:1. The applications of MOBILE's in parallel processing architectures such as cellular automata and cellular neural networks are discussed based on the above results. Circuit simulations using a simple model of resonant tunneling transistors successfully reproduce the basic characteristics of MOBILE's, and demonstrate the usefulness of MOBILE's in such applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
