Modeling and Analyzing Duty-Cycling Pipelined-Scheduling MAC for Linear Sensor Networks (2015)

Linear sensor networks (LSNs) have recently attracted increasing attention due to the vast requirements on the monitoring and surveillance of a structure or an area with a linear topology. However, there is not a lot of work on network modeling and analysis based on a duty-cycling medium access control (MAC) protocol for LSNs. In this paper, we model a duty-cycling MAC with a pipelined-scheduling feature for an LSN, where each node is responsible for monitoring a certain area and can generate packets according to its sensed results. Based on the model, we analyze the network performance in terms of system throughput, active time ratio per cycle of each node, and packet delivery latency. Through extensive OPNET-based simulations, we validate the model and reveal the dependence of the network performance on various system parameters. Apart from enabling the effective estimation of the protocol performance by using our model, we believe that our model and analysis could provide an insightful understanding on the behavior of a duty-cycling MAC protocol and aid in its design and optimization for a multihop LSN.
Genetic Analyses of<i>Schizosaccharomyces pombe dna2</i>+ Reveal That Dna2 Plays an Essential Role in Okazaki Fragment Metabolism (2000)

In this report, we investigated the phenotypes caused by temperature-sensitive (ts) mutant alleles of dna2(+) of Schizosaccharomyces pombe, a homologue of DNA2 of budding yeast, in an attempt to further define its function in vivo with respect to lagging-strand synthesis during the S-phase of the cell cycle. At the restrictive temperature, dna2 (ts) cells arrested at late S-phase but were unaffected in bulk DNA synthesis. Moreover, they exhibited aberrant mitosis when combined with checkpoint mutations, in keeping with a role for Dna2 in Okazaki fragment maturation. Similarly, spores in which dna2(+) was disrupted duplicated their DNA content during germination and also arrested at late S-phase. Inactivation of dna2(+) led to chromosome fragmentation strikingly similar to that seen when cdc17(+), the DNA ligase I gene, is inactivated. The temperature-dependent lethality of dna2 (ts) mutants was suppressed by overexpression of genes encoding subunits of polymerase delta (cdc1(+) and cdc27(+)), DNA ligase I (cdc17(+)), and Fen-1 (rad2(+)). Each of these gene products plays a role in the elongation or maturation of Okazaki fragments. Moreover, they all interacted with S. pombe Dna2 in a yeast two-hybrid assay, albeit to different extents. On the basis of these results, we conclude that dna2(+) plays a direct role in the Okazaki fragment elongation and maturation. We propose that dna2(+) acts as a central protein to form a complex with other proteins required to coordinate the multienzyme process for Okazaki fragment elongation and maturation.
Optical feedback in active matrix polymer OLED displays (2004)

Among the recent emerging flat display technologies organic LED (OLED) is one of the most interesting. Combining the OLED with an active matrix substrate, typically made with low temperature polysilicon, it is possible to greatly reduce the power consumption. In an active matrix substrate the ability of integrating active components can be used to mitigate the OLED differential degradation.

Word integration and regression programming during reading: A test of the E-Z reader 10 model. (2009)

Participants read sentences with two types of target nouns, one that did and one that did not require a determiner to form a legal verb-noun phrase sequence. Sentences were presented with and without the critical determiner to create a local noun integration difficulty when a required determiner was missing. The absence of a required determiner did not influence 1st-pass reading of the verb, the noun, and the posttarget word. It did, however, have a profound effect on 2nd-pass reading. All three words were a likely target of a regression when a required determiner was missing, and the noun and the posttarget word were likely sources of a regression. These results are consistent with novel E-Z reader model assumptions, according to which identification of the noun should be followed by its integration, and integration difficulties can lead to the initiation of a regression to the noun. However, integration difficulties influenced eye movements earlier and later than predicted by the new model.
A Mean-Value Model for Control of Homogeneous Charge Compression Ignition (HCCI) Engines (2004)

Abstract A Mean Value Model (MVM) for a Homogeneous Charge Compression Ignition (HCCI) engine is presented. Using a phenomenological zero-dimensional approach with five continuous and three discrete states we first model the effects of the Exhaust Gas Recirculation (EGR) valve, the exhaust Rebreathing Lift (RBL), and the fueling rate on the state of charge in the cylinder at intake valve closing. An Arrhenius integral is then used to model the start of combustion, θsoc. A series of simple algebraic relations that captures the combustion duration and heat release is finally used to model the state of charge after the HCCI combustion and the Location of Peak Pressure (LPP). The model is parametrized and validated using steady-state test data from an experimental gasoline engine at the General Motors Corporation. The simple model captures the temperature, pressure, air-to-fuel ratio, and inert gas fraction of the exhausted mass flow. This characterization is important for the overall HCCI dynamics because the thermodynamic state (pressure, temperature) and concentration (oxygen and inert gas) of the exhausted mass flow affect the next combustion event. The high dilution level in HCCI engines increases the significance of this internal feedback that generally exists to a smaller extent in conventional spark-ignition and compression-ignition internal combustion engines.
Articulated Billboards for Video‐based Rendering (2010)

Abstract We present a novel representation and rendering method for free‐viewpoint video of human characters based on multiple input video streams. The basic idea is to approximate the articulated 3D shape of the human body using a subdivision into textured billboards along the skeleton structure. Billboards are clustered to fans such that each skeleton bone contains one billboard per source camera. We call this representation articulated billboards . In the paper we describe a semi‐automatic, data‐driven algorithm to construct and render this representation, which robustly handles even challenging acquisition scenarios characterized by sparse camera positioning, inaccurate camera calibration, low video resolution, or occlusions in the scene. First, for each input view, a 2D pose estimation based on image silhouettes, motion capture data, and temporal video coherence is used to create a segmentation mask for each body part. Then, from the 2D poses and the segmentation, the actual articulated billboard model is constructed by a 3D joint optimization and compensation for camera calibration errors. The rendering method includes a novel way of blending the textural contributions of each billboard and features an adaptive seam correction to eliminate visible discontinuities between adjacent billboards textures. Our articulated billboards do not only minimize ghosting artifacts known from conventional billboard rendering, but also alleviate restrictions to the setup and sensitivities to errors of more complex 3D representations and multiview reconstruction techniques. Our results demonstrate the flexibility and the robustness of our approach with high quality free‐viewpoint video generated from broadcast footage of challenging, uncontrolled environments.
Efferent projections of the subthalamic nucleus in the rat: Light and electron microscopic analysis with the PHA‐L method (1987)

Efferent projections of rat subthalamic nucleus were studied by use of the axonal transport of phaseolus vulgaris-leucoagglutinin (PHA-L), and the results were analyzed with light and electron microscopes. PHA-L injections in the subthalamic nucleus (STH) resulted in heavy labeling of fiber plexus with en passant boutons and terminals in the pallidal complex, i.e., the entopeduncular nucleus (EP), the globus pallidus (GP) and the ventral pallidum (VP), and the substantia nigra pars reticulata (SNR). Labeling in GP was characterized by two distinct bands of labeled terminals oriented dorsoventrally, whereas labeling in SNR was patchy. STH efferents to the pallidum and SNR displayed a mediolateral topographic organization. With regard to dorsoventral organization, projections to GP were inverted, but those to SNR were not. There were moderate projections to the neostriatum and sparse projections to the frontal cortex, substantia innominata, substantia nigra pars compacta (SNC), pedunculopontine tegmental nucleus, ventral part of the central gray matter including the dorsal raphe nucleus, and the mesencephalic and pontine reticular formation. PHA-L injections in the zona incerta and the lateral hypothalamic area resulted in fiber and terminal labelings in many structures, including the basal forebrain, EP, SNC, and other brainstem areas that overlap with some of the terminal sites of STH projections. Ultrastructural observations of PHA-L labeled processes in GP and SNR revealed that STH terminals in both structures contained small pleomorphic vesicles and formed asymmetrical contacts. These contacts were mainly on dendritic shafts, but some were on somata. It also was observed that the myelinated axons of STH neurons lost their myelin after reaching their target areas and the synaptic boutons arose from relatively thin unmyelinated axons.

Spatial and temporal linking of epicardial activation directions during ventricular fibrillation in dogs. Evidence for underlying organization. (1992)

Electrical activation during VF is organized. The degree of linking of EA directions during VF is not affected by the presence of MI, the site of recording, or repeated inductions of VF. During the first 5 seconds of VF, the degree of linking decreases.
Single Phase Liquid Immersion Cooling of Discrete Heat Sources in a Vertical Channel. (1987)

Natural convection liquid cooling of simulated electronic components was investigated. A single column of eight protruding components was constructed using foil heaters mounted on the back of stainless steel rectangular blocks. These components were attached to a vertical plexiglas wall to simulate a column of 20 pin DIP'S. A channel was formed by placing a smooth movable shrouding wall parallel to the test surface. The test surface and the shrouding wall were placed in a water immersion bath. Flow visualization was accomplished using a laser generated plane of light to illuminate suspended particles. Photographs were taken of the flow at the test surface mid-plane for four different power settings at each of three different channel widths. A nondimensional temperature and a modified Grashof number for each heated protrusion at each input power setting and channel width were determined. Visual results indicate two distinct flow regions. Far away from the components, a natural convection boundary layer flow was observed. Near the components, the flow was modified by the protrusions. As the component heat input increased, more pronounced three dimensional effects were noticed. Temperature measurements indicate that as the modified Grashof numbers increased, the nondimensional temperatures decreased for each component. Also, the difference in the nondimensional temperatures for various components decreased with increasing modified Grashof numbers.
A novel control strategy for input-parallel-output-series inverter system (2011)

This paper presents the topology structure and control method for input-parallel-output-series (IPOS) inverter system which is suitable for high input current, high output voltage and high power applications. In order to ensure the normal operation of IPOS inverter system, the control method should achieve input current sharing (ICS) and output voltage sharing (OVS) among constituent modules. Through the analysis in this paper, input current sharing is automatically achieved as long as output voltage sharing is controlled. IPOS inverter system is controlled by three-loop control which is composed of outer common output voltage loop, inner current loops and voltage sharing loops. Simulation results show that this control strategy can achieve low total harmonic distortion (THD) in the system output voltage, fast dynamic response and good output voltage sharing performance.

Is It Time to Punt Paper? Point/Counterpoint. (2005)

Augmented apoptotic signaling can result in degradation of skeletal muscle proteins and loss of myonuclei, ultimately contributing to muscle atrophy and contractile dysfunction. Apoptosis repressor with caspase recruitment domain (ARC) is an anti-apoptotic protein highly expressed in skeletal muscle. Here we examined the role of ARC on age-related skeletal muscle apoptosis and wasting by utilizing an ARC-deficient mouse model. Aged mice displayed a number of morphological, phenotypic, and contractile alterations in both soleus and plantaris muscle with aging. Although no differences were found in proteolytic enzyme activity, ARC protein decreased while several anti-apoptotic proteins (e.g., BCL2, BCLXL, HSP70, and XIAP) and the release of mitochondrial housed protein (i.e., SMAC, AIF) increased in aged muscle. Importantly, ARC KO mice had low muscle weights and fewer fibers in soleus, with 2-year-old ARC KO mice displaying lower mitochondrial BCL2 protein along with augmented release of CYTC and SMAC in red/oxidative muscle. Overall, these results indicate that aged skeletal muscle undergoes atrophy as well as contractile and fiber type composition alterations despite an increase in anti-apoptotic protein expression. Although some mitochondrial-specific apoptotic alterations occurred in skeletal muscle due to ARC ablation over the lifespan, our data suggest that ARC may not have a large influence during skeletal muscle aging.
Timing analysis of industrial real-time systems (2002)

We describe a formal method for modelling real-time systems and a procedure to compute the model's timing characteristics automatically. We present algorithms that compute exact bounds on the delay between two specified events. We also describe an algorithm to count the minimum and maximum number of times an event occurs between a given starting condition and an ending condition. These algorithms are based on symbolic model checking techniques which have been successfully used to find bugs in several industrial designs. Such techniques can be used to search exhaustively state spaces with up to 10/sup 30/ states. To illustrate the usefulness of our method, we describe the timing analysis for a patient monitoring system with more than 10/sup 13/ states. We also present the timing analysis and verification for an aircraft controller. The sizes of the examples we verify demonstrate that our tool can be applied to realistic industrial designs.
Adaptive Correction of Sampling Bias in Dynamic Call Graphs (2015)

This article introduces a practical low-overhead adaptive technique of correcting sampling bias in profiling dynamic call graphs. Timer-based sampling keeps the overhead low but sampling bias lowers the accuracy when either observable call events or sampling actions are not equally spaced in time. To mitigate sampling bias, our adaptive correction technique weights each sample by monitoring time-varying spacing of call events and sampling actions. We implemented and evaluated our adaptive correction technique in Jikes RVM, a high-performance virtual machine. In our empirical evaluation, our technique significantly improved the sampling accuracy without measurable overhead and resulted in effective feedback directed inlining.

Active low-frequency modal noise cancellation for room acoustics: an experimental study (2009)

Low frequency background noise in rooms generated by numbers of human activities- traffic, railway, airport and industrial noise- creates major disturbances from loss of speech intelligibility to stress and fatigue. To overcome such situations classical solutions generally consist in deploying resonator-like absorbing materials to reduce both the acoustic level and the reverberation time. Unfortunately these traditional acoustic treatments are not efficient enough to attain A-weighted level specifications imposed by regulation laws. In the context of cancellation of low frequencies in rooms, an experiment was performed to qualify and quantify performances of a low-frequency noise cancellation active system. So as to minimize and increase performance in noise reduction, active solutions are actually studied to attain and fulfill high expectations in terms of integration with high efficiency in opposite to passive solutions. We propose an experiment based on active sources to counteract modal low frequency noise for quasi-stationary to permanent noise emission. We present some results using a step-by-step approach to understand the global behavior of the room excited in the frequency band of its first modes. Through coherent assumptions and observations we show the efficiency of low-power active system with a priori constraints affecting modal active control. 1.
Clinical trials in multiple sclerosis: milestones (2018)

The achievements in multiple sclerosis (MS) therapeutics are founded on the outcomes of clinical trials that demonstrate quantifiable results in treating a disease with an unpredictable course. Much has changed since the early trials in MS from the mid-20th century that compared a potential therapeutic agent with a placebo and measured outcomes based on patients' subjective reports. Advancements over the past decades have simplified diagnosis of the disease and allowed for more quantitative monitoring of its progression alongside support from paraclinical studies. Further collaborative efforts have led to pivotal meetings that steered the direction of future trials and the creation of patient databases that provided important epidemiologic information on trial subjects. These innovations and changes have improved MS clinical trials but challenge future trials to create more efficient designs lest the pace of progress necessarily slows because of the increased time to conduct such studies. As treatment options for MS broaden, clinical trials will continue to incorporate new strategies to identify novel therapies and pathways of intervention.
Comparative study of thermally conductive fillers for use in liquid encapsulants for electronic packaging (1999)

Thermal management plays a very vital role in the packaging of high performance electronic devices. Effective heat dissipation is crucial to enhance the performance and reliability of the packaged devices. Liquid encapsulants used for glob top, potting, and underfilling applications can strongly influence the package heat dissipation. Unlike molding compounds, the filler loading in these encapsulants is restrained. This paper deals with the development and characterization of thermally conductive encapsulants with relatively low filler loading. A comparative study on the effect of different ceramic fillers on the thermal conductivity and other critical properties of an epoxy based liquid encapsulant is presented.

Solution processible organic transistors and circuits based on a C70 methanofullerene (2005)

We demonstrate ambipolar charge transport in organic field-effect transistors based on the solution processible methanofullerene [6,6]-phenyl-C71-butyric acid methyl ester ([70]PCBM). The electron mobility measured in the linear and saturated regimes is approximately equal and of the order of 1×10−3cm2∕Vs. In the linear regime, mobility is thermally activated with a strong gate bias dependence. The p-channel hole mobility is lower with a maximum value of 2×10−5cm2∕Vs. The n- and p-channel operations are characterized by a low (∼∣3∣V) and a high (∼∣50∣V) switch-on voltage, respectively, with the on-off current ratio on the order of 104 for both channels. Although the present findings are qualitatively similar to those reported previously for C60-methanofullerene-based transistors, [70]PCBM devices are more stable and easier to reproduce. By making use of this property we are able to demonstrate functional unipolar and complementarylike logic circuits with promising operating characteristics.
