Aspects of NVH Integration in Hybrid Vehicles (2009)

<div class="htmlview paragraph">NVH refinement is an important aspect of the powertrain development and vehicle integration process. The depletion of fossil-based fuels and increase in price of gasoline have prompted most vehicle manufacturers to embrace propulsion technologies with varying degrees and types of hybridization. Many different hybrid vehicle systems are either on the market, or under development, even up to all-electric vehicles. Each hybrid vehicle configuration brings unique NVH challenges that result from a variety of sources. This paper begins with an introductory discussion of hybrid propulsion technologies and associated unique vehicle NVH challenges inherent in the operation of such hybrid vehicles.</div> <div class="htmlview paragraph">Following this, the paper outlines a two-dimensional landscape of typical customer vehicle maneuvers mapped against hybrid electric vehicle (HEV) operational modes. Overlaid on this map are NVH issues such as those associated with global powertrain vibration, driveline vibration, HEV component-specific noise, motor/generator whine, accessory noise, gear rattle, and noise pattern changes. The remainder of the paper focuses on specific examples from case studies illustrating key HEV NVH issues such as engine start/stop behavior, motor/generator whine, and influence of electric machines on powerplant integration issues. The use of advanced time-domain methods such as vehicle interior noise simulation (VINS) to understand and optimize HEV vehicle NVH behavior is shown. Finally, the findings from the discussed studies are summarized and appropriate conclusions are drawn with respect to understanding, characterizing, and solving unique hybrid vehicle NVH issues.</div>

Fire as an Agent in Rock Weathering (1927)

In the semi-arid, forested mountains of western United States, fire seems to rank first in causing the disruption of bowlders and rock outcrops. This paper contains the result of experiments on the sudden heating of rocks, and considers the field evidence regarding this and related aspects of weathering.
Operation characteristics of a new liquid-solid circulating moving bed reactor (2003)

The liquid-solid circulating moving bed reactor is a novel one, which consists of two or more reaction chambers and a particle transport system. Particles move down to the lower reaction chamber from the upper reaction chamber through an upper conduit and to the particle transport system through a lower conduit, and then are conveyed into the upper reaction chamber through a riser. The circulating rate of particles and the flow of liquid in the two conduits are key factors to the continuous steady operation of the reactor; they can be controlled by varying operating conditions: the outlet liquid flow rate in the regeneration chamber, the outlet liquid flow rate in the reaction chamber, the inlet liquid flow rate of the reactants, and the flow rate of driving flow. A flow model has been proposed to quantify the operation characteristics of the reactor. The results predicted by the model show satisfactory agreement with the experimental data.
Quantitative modeling of triacylglycerol homeostasis in yeast – metabolic requirement for lipolysis to promote membrane lipid synthesis and cellular growth (2008)

Triacylglycerol metabolism in Saccharomyces cerevisiae was analyzed quantitatively using a systems biological approach. Cellular growth, glucose uptake and ethanol secretion were measured as a function of time and used as input for a dynamic flux-balance model. By combining dynamic mass balances for key metabolites with a detailed steady-state analysis, we trained a model network and simulated the time-dependent degradation of cellular triacylglycerol and its interaction with fatty acid and membrane lipid synthesis. This approach described precisely, both qualitatively and quantitatively, the time evolution of various key metabolites in a consistent and self-contained manner, and the predictions were found to be in excellent agreement with experimental data. We showed that, during pre-logarithmic growth, lipolysis of triacylglycerol allows for the rapid synthesis of membrane lipids, whereas de novo fatty acid synthesis plays only a minor role during this growth phase. Progress in triacylglycerol hydrolysis directly correlates with an increase in cell size, demonstrating the importance of lipolysis for supporting efficient growth initiation.

Single Photon Ionization Time-of-Flight Mass Spectrometry with a Pulsed Electron Beam Pumped Excimer VUV Lamp for On-Line Gas Analysis:  Setup and First Results on Cigarette Smoke and Human Breath (2005)

Single-photon ionization (SPI) using vacuum ultraviolet (VUV) light produced by an electron beam pumped rare gas excimer source has been coupled to a compact and mobile time-of-flight mass spectrometer (TOFMS). The novel device enables real-time on-line monitoring of organic trace substances in complex gaseous matrixes down to the ppb range. The pulsed VUV radiation of the light source is employed for SPI in the ion source of the TOFMS. Ion extraction is also carried out in a pulsed mode with a short time delay with respect to ionization. The experimental setup of the interface VUV light source/time-of-flight mass spectrometer is described, and the novel SPI-TOFMS system is characterized by means of standard calibration gases. Limits of detection down to 50 ppb for aliphatic and aromatic hydrocarbons were achieved. First on-line applications comprised real-time measurements of aromatic and aliphatic trace compounds in mainstream cigarette smoke, which represents a highly dynamic fluctuating gaseous matrix. Time resolution was sufficient to monitor the smoking process on a puff-by-puff resolved basis. Furthermore, human breath analysis has been carried out to detect differences in the breath of a smoker and a nonsmoker, respectively. Several well-known biomarkers for smoke could be identified in the smoker's breath. The possibility for even shorter measurement times while maintaining the achieved sensitivity makes this new device a promising tool for on-line analysis of organic trace compounds in process gases or biological systems.
Mechanical Deformation of a Lithium-Metal Anode Due to a Very Stiff Separator (2014)

This work builds on the two-dimensional model presented by Ferrese et al. [J. Electrochem. Soc., 159, A1615 (2012)], which captures the movement of lithium metal at the negative electrode during cycling in a Li-metal/LiCoO2 cell. In this paper, the separator is modeled as a dendrite-inhibiting polymer separator with an elastic modulus of 16 GPa. The separator resists the movement of lithium through the generation of stresses in the cell. These stresses affect the negative electrode through two mechanisms –altering the thermodynamics of the negative electrode and deforming the negative electrode mechanically. From this analysis, we find that the dendrite-inhibiting separator causes plastic and elastic deformation of the lithium at the negative electrode which flattens the electrode considerably when compared to the liquid-electrolyte case. This flattening of the negative electrode causes only very slight differences in the local state of charge in the positive electrode. When comparing the magnitude of the effects flattening the negative electrode, we find that the plastic deformation plays a much larger role than either the pressure-modified reaction kinetics or elastic deformation. This is due to the low yield strength of the lithium metal, which limits the stresses such that they have only a small effect on the reaction kinetics.
Long-term impacts of antibiotic exposure on the human intestinal microbiota (2010)

Although it is known that antibiotics have short-term impacts on the human microbiome, recent evidence demonstrates that the impacts of some antibiotics remain for extended periods of time. In addition, antibiotic-resistant strains can persist in the human host environment in the absence of selective pressure. Both molecular- and cultivation-based approaches have revealed ecological disturbances in the microbiota after antibiotic administration, in particular for specific members of the bacterial community that are susceptible or alternatively resistant to the antibiotic in question. A disturbing consequence of antibiotic treatment has been the long-term persistence of antibiotic resistance genes, for example in the human gut. These data warrant use of prudence in the administration of antibiotics that could aggravate the growing battle with emerging antibiotic-resistant pathogenic strains.
Synthesis and optical properties of GaN/ZnO solid solution nanocrystals (2010)

We devised a synthesis route to prepare narrow band gap GaN/ZnO solid solution nanocrystals via nitriding a homogeneous Ga-Zn-O nanoprecursor. The nanocrystals were characterized by several following methods: x-ray diffractometer, transmission electron microscopy, ultraviolet-visible diffuse reflection, and Raman spectroscopy. Here, we can control the composition of nanocrystals by the nitridation temperature. From 550 to 850 °C, the corresponding crystalline size varies from 6.1 to 27 nm. It has been demonstrated that the sample prepared at 650 °C had the narrowest band gap of 2.21 eV. Microstructural investigations show that the (101) surface is the predominantly exposed one for the GaN/ZnO solid solution nanocrystals. We also discuss the influence of chemical disorder based on the Raman spectra acquired.
Invertebrates and fire—challenges and opportunities for conserving biodiversity (2012)

Fires, whether planned or unplanned, impact upon a suite of organisms in natural ecosystems. Direct (short-term) and indirect (longer term) effects influence the composition and structure of invertebrate communities through the interaction of site history, characteristics of individual fire events and species life-history traits. Prediction of fire responses based on vascular plant species life-history traits, and the development of a functional classification based on shared traits, underpins current fire management in south-eastern Australia. Can a similar approach be developed for terrestrial invertebrates, or should we focus on utilising a framework based on surrogates developed around vegetation composition and structure, or taxonomic alternatives? This paper considers whether the use of surrogates offers promise as a strategy of dealing with the complexity of invertebrate biodiversity and associated issues surrounding fire management. It proposes a functional approach, based on species’ life-history traits, that can complement existing strategies; and identifies opportunities that have potential for resolving existing challenges in biodiversity conservation in fire-prone environments.
CDD: a conserved domain database for interactive domain family analysis (2006)

The conserved domain database (CDD) is part of NCBI's Entrez database system and serves as a primary resource for the annotation of conserved domain footprints on protein sequences in Entrez. Entrez's global query interface can be accessed at http://www.ncbi.nlm.nih.gov/Entrez and will search CDD and many other databases. Domain annotation for proteins in Entrez has been pre-computed and is readily available in the form of 'Conserved Domain' links. Novel protein sequences can be scanned against CDD using the CD-Search service; this service searches databases of CDD-derived profile models with protein sequence queries using BLAST heuristics, at http://www.ncbi.nlm.nih.gov/Structure/cdd/wrpsb.cgi. Protein query sequences submitted to NCBI's protein BLAST search service are scanned for conserved domain signatures by default. The CDD collection contains models imported from Pfam, SMART and COG, as well as domain models curated at NCBI. NCBI curated models are organized into hierarchies of domains related by common descent. Here we report on the status of the curation effort and present a novel helper application, CDTree, which enables users of the CDD resource to examine curated hierarchies. More importantly, CDD and CDTree used in concert, serve as a powerful tool in protein classification, as they allow users to analyze protein sequences in the context of domain family hierarchies.

Effect of Side Chains and Sulfonic Groups on the Performance of Polycarboxylate-Type Superplasticizers in Concentrated Cement Suspensions (2011)

Polycarboxylate-type superplasticizers (PCs) containing different side chains and sulfonic groups have been synthesized, and the effect of side chains and sulfonic groups on their performance in cementitious systems has been intensively investigated by measuring zeta potential, thickness of absorption layer, paste fluidity, rheological properties as well as the setting time in this paper. Results show that the PC containing both short poly(ethylene oxide) (PEO) side chains and long PEO side chains with the molar ratio of 1:1 has a better dispersibility than the PC containing only short PEO side chains or only long PEO side chains in cement suspensions. The shorter the side chain of the PC, the longer the setting time of cement paste incorporating it. An appropriate increase of sulfonic group content is beneficial for the improvement of dispersibility for the PC and leads to no obvious change for the setting time. It also suggests that there is a geometrical balance between the PEO side chains and sulfonic groups for the performance of PC. This work is not only helpful for understanding the relationship of molecular structure of PCs and their performance, but also further designing optimum molecular structure of PC to meet the requirement in different concrete system.
Heterogeneous Scheduling of Deep Neural Networks for Low-power Real-time Designs (2019)

Deep neural networks have become the readiest answer to a range of application challenges including image recognition, stock analysis, natural language processing, and biomedical applications such as seizure detection. All while outperforming prior leading solutions that relied heavily on hand-engineered techniques. However, deployment of these neural networks often requires high-computational and memory-intensive solutions. These requirements make it challenging to deploy Deep Neural Networks (DNNs) in embedded, real-time low-power applications where classic architectures, GPUs and CPUs, still impose significant power burden. Systems-on-Chip (SoC) with Field-programmable Gate Arrays (FPGAs) can be used to improve performance and allow more fine-grain control of resources than CPUs or GPUs, but it is difficult to find the optimal balance between hardware and software to improve DNN efficiency. In the current research literature there have been few proposed solutions to address optimizing hardware and software deployments of DNNs in embedded low-power systems. To address the computation resource restriction and low-power needs for deploying these networks, we describe and implement a domain-specific metric model for optimizing task deployment on differing platforms, hardware and software. Next, we propose a DNN hardware accelerator called Scalable Low-power Accelerator for real-time deep neural Networks (SCALENet) that includes multithreaded software workers. Finally, we propose a heterogeneous aware scheduler that uses the DNN-specific metric models and the SCALENet accelerator to allocate a task to a resource based on solving a numerical cost for a series of domain objectives. To demonstrate the applicability of our contribution, we deploy nine modern deep network architectures, each containing a different number of parameters within the context of two different neural network applications: image processing and biomedical seizure detection. Utilizing the metric modeling techniques integrated into the heterogeneous aware scheduler and the SCALENet accelerator, we demonstrate the ability to meet computational requirements, adapt to multiple architectures, and lower power by providing an optimized task to resource allocation. Our heterogeneous aware scheduler improves power saving by decreasing power consumption by 10% of the total system power, does not affect the accuracy of the networks, and still meets the real-time deadlines. We demonstrate the ability to achieve parity with or exceed the energy efficiency of NVIDIA GPUs when evaluated against Jetson TK1 with embedded GPU SoC and with a 4× power savings in a power envelope of 2.0W. When compared to existing FPGA-based accelerators, SCALENet’s accelerator and heterogeneous aware scheduler achieves a 4× improvement in energy efficiency.
Microanatomic clonality of gamma delta T cells in human leishmaniasis lesions (1992)

T cells bearing gamma delta Ag receptors accumulate in the lesions of patients with localized American cutaneous leishmaniasis (LCL), and are thought to be involved in immunity to the parasite. To obtain clues as to the nature of the Ag recognized by these cells, we analyzed the diversity of the TCR delta-chain in LCL lesions. Using mAb against variable (V) encoded determinants with immunoperoxidase, both V delta 1 and V delta 2 subpopulations were identified in the dermal granulomas. However, within the epidermis of LCL lesions, the majority of the gamma delta T cells were V delta 1 positive. PCR analysis of lesion-derived DNA using oligonucleotide primers for V and junctional (J) gene segments revealed preferential usage of J delta 1 in lesions compared with the peripheral blood of these patients. Nucleotide sequence analysis of the V-J junction indicated limited diversity of gamma delta T cells within specific microanatomic regions. In addition, use of a single diversity (D) gene segment, D delta 3, in V delta 2 cells in lesions was observed, as opposed to multiple D delta gene segment usage in the blood of the same individuals. The distribution, gene segment usage and clonality of gamma delta T cells in lesions of leishmaniasis was remarkably similar to that observed in leprosy. Therefore, gamma delta T cells responding to infection may recognize a limited set of nominal Ag, perhaps common to distinct pathogens and/or those expressed by the host. Our findings are most consistent with a model in which specific gamma delta T cells are clonally selected by these Ag in lesions and undergo oligoclonal expansion within a microanatomic region.
Socialtrust (2008)

Web 2.0 promises rich opportunities for information sharing, electronic commerce, and new modes of social interaction, all centered around the "social Web" of user-contributed content, social annotations, and person-to-person social connections. But the increasing reliance on this "social Web" also places individuals and their computer systems at risk, creating opportunities for malicious participants to exploit the tight social fabric of these networks. With these problems in mind, we propose the SocialTrust framework for tamper-resilient trust establishment in online communities. SocialTrust provides community users with dynamic trust values by (i) distinguishing relationship quality from trust; (ii) incorporating a personalized feedback mechanism for adapting as the community evolves; and (iii) tracking user behavior. We experimentally evaluate the SocialTrust framework using real online social networking data consisting of millions of MySpace profiles and relationships. We find that SocialTrust supports robust trust establishment even in the presence of large-scale collusion by malicious participants.
