A Broad-Band Microwave Relay System between New York and Boston (1949)

This paper describes the principal features of a broad-band microwave relay system which has recently been installed between New York and Boston. The system operates at frequencies around 4,000 Mc and provides two two-way channels, each accommodating a signal-frequency band extending from 30 cps to 4.5 Mc. Noise and distortion characteristics are satisfactory for the transmission of several hundred simultaneous telephone conversations or a standard black-and-white television program.
Data Visualization in Sociology (2014)

Visualizing data is central to social scientific work. Despite a promising early beginning, sociology has lagged in the use of visual tools. We review the history and current state of visualization in sociology. Using examples throughout, we discuss recent developments in ways of seeing raw data and presenting the results of statistical modeling. We make a general distinction between those methods and tools designed to help explore datasets, and those designed to help present results to others. We argue that recent advances should be seen as part of a broader shift towards easier sharing of the code and data both between researchers and with wider publics, and encourage practitioners and publishers to work toward a higher and more consistent standard for the graphical display of sociological insights.

Reliable, High Repetition Rate Thyratron Grid Driver Used With A Magnetic Modulator (2005)

The Atomic Vapor Laser Isotope Separation (AVLIS) Program at Lawrence Livermore National Laboratory uses a magnetic modulator switched by a high voltage thyratron to drive a gas discharge laser. The thyratron trigger source must provide an extremely reliable, low jitter, high-rep-rate grid pulse. This paper describes a thyratron grid driver which delivers a 1.2 kV, 80 ns rise time grid pulse into a 50 ohm load at up to 4.5 kHz repetition rate and has demonstrated approximately 10,000 hours MTBF. Since the thyratron is used with a magnetic compression circuit having a delay time of 1.4 ms this grid driver incorporates a jitter compensation circuit to adjust the trigger timing of the thyratron to provide overall modulator/laser jitter of less than /spl plusmn/2 ns. The specific grid driver requirements will be discussed followed by a description of the circuit design and theory of operation. Construction comments will be followed by performance data (for a specific thyratron and magnetic compression circuit), including pulse shape, jitter, and lifetime.

SPATIAL TEMPORAL SOWING PATTERN OF RAPESEED-MUSTARD CROP IN INDIA USING MULTI-DATE IRS AWIFS DATA (2012)

Abstract. This paper highlights the results on spatial pattern of sowing of rapeseed/mustard in four major states in India using multidate Advanced Wide Field Sensor (AWiFS) data for 2010-11 crop season. Geo-referenced, calibrated AWiFS data acquired during October 2010 to February 2011 were used to generate the Normalised Difference Vegetation Index (NDVI) image sets. Iterative Self-Organizing Data Analysis Technique (ISODATA) based clustering of the multi date NDVI dataset for mustard crop pixels was performed. The clusters were segregated to spectral emergence classes using a spectral profile matching approach with reference to ground truth data. The sowing dates were derived from the spectral emergence data using a lag period based on field observation. Analysis showed the sowing pattern in the study states is spread over around 60 days from mid October to mid December. Three distinct clusters of sowing pattern were observed. The major one (around 40%) is sown between mid October and first week of November. Around 25% area is sown from last week of November to mid December. The other 35% area is sown in between these two periods. Analysis of temperature, a key weather variable influencing the growth of this crop, showed that the crop sowing in northern Rajasthan and Haryana is delayed by about one month to avoid the frost damage during reproductive phase. In the parts of Gujarat, southern parts of Rajasthan and Madhya Pradesh (MP), an early sowing in the second fortnight of October was observed, mainly to avoid higher mean temperatures during the month of March.
Pharmacological Targeting of Protease-Activated Receptor 2 Affords Protection from Bleomycin-Induced Pulmonary Fibrosis (2015)

Idiopathic pulmonary fibrosis is the most devastating diffuse fibrosing lung disease that remains refractory to therapy. Despite increasing evidence that protease-activated receptor 2 (PAR-2) contributes to fibrosis, its importance in pulmonary fibrosis is under debate. We addressed whether PAR-2 deficiency persistently reduces bleomycin-induced pulmonary fibrosis or merely delays disease progression and whether pharmacological PAR-2 inhibition limits experimental pulmonary fibrosis. Bleomycin was instilled intranasally into wild-type or PAR-2-deficient mice in the presence/absence of a specific PAR-2 antagonist (P2pal-18S). Pulmonary fibrosis was consistently reduced in PAR-2-deficient mice throughout the fibrotic phase, as evident from reduced Ashcroft scores (29%) and hydroxyproline levels (26%) at d 28. Moreover, P2pal-18S inhibited PAR-2-induced profibrotic responses in both murine and primary human pulmonary fibroblasts (p < 0.05). Once daily treatment with P2pal-18S reduced the severity and extent of fibrotic lesions in lungs of bleomycin-treated wild-type mice but did not further reduce fibrosis in PAR-2-deficient mice. Importantly, P2pal-18S treatment starting even 7 d after the onset of fibrosis limits pulmonary fibrosis as effectively as when treatment was started together with bleomycin instillation. Overall, PAR-2 contributes to the progression of pulmonary fibrosis, and targeting PAR-2 may be a promising therapeutic strategy for treating pulmonary fibrosis.

Optimal Resource Allocation for Multi-D2D Links Underlying OFDMA-Based Communications (2012)

This paper analyzes the optimal resource allocation for multi-D2D(Device-to-Device) links underlying OFDMA-based networks with the target of reaching maximum sum-throughput of D2D transmission. In order to guarantee QoS (Quality of Service) of cellular users, the rate loss of cellular users is limited by a lower-bound constraint RLC. Meanwhile, the D2D link is allowed to use a sub-carrier only when the throughput from spectrum reusing exceeds a certain threshold. Since the primal problem is non-convex, we solve it through a subgradient-based algorithm by applying Lagrangian dual theory. The numerical results demonstrate the effectiveness and convergence of the algorithm by comparison with water-filling-based method. Besides, the subcarrier-specific RLC is more relaxed than the user-specific RLC for D2D transmission, which means D2D transmission can reach higher throughput under the latter constraint.

Bayesian Hierarchical Mixtures of Experts (2012)

The Hierarchical Mixture of Experts (HME) is a well-known tree-based model for regression and classification, based on soft probabilistic splits. In its original formulation it was trained by maximum likelihood, and is therefore prone to over-fitting. Furthermore the maximum likelihood framework offers no natural metric for optimizing the complexity and structure of the tree. Previous attempts to provide a Bayesian treatment of the HME model have relied either on ad-hoc local Gaussian approximations or have dealt with related models representing the joint distribution of both input and output variables. In this paper we describe a fully Bayesian treatment of the HME model based on variational inference. By combining local and global variational methods we obtain a rigourous lower bound on the marginal probability of the data under the model. This bound is optimized during the training phase, and its resulting value can be used for model order selection. We present results using this approach for a data set describing robot arm kinematics.

The CT's sample volume as an approximate, instrumental measure for density resolution in densitometry of the lung (1997)

Ultimately CT-densitometry of the lung should give comparable results on all scanners. One prerequisite for this is the use of the same density resolution. Unfortunately, density resolution is impractical as a performance specifying parameter because it depends on the cellular material scanned. Therefore, another parameter that can be used for scanner and protocol characterization, and that does not depend on a special phantom, would be highly preferable. We investigated how well the CT's nominal sample volume (V), calculated from section thickness and in-plane spatial resolution as specified by the CT manufacturer, can serve as a simple measure, for density resolution. Six CT scanners were studied using foam and lung phantoms. On all scanners we observed for foam an approximately linear relation between density resolution and V-1/2. Density resolution on different scanners varied to some extent. These differences can be interpreted as being caused by deviations of the true sample volume from the nominal value: the 95%-confidence interval runs for instance for V = 8 mm3 from 4.6 mm3 to 16.9 mm3. Acceptability of this spread depends on the consequences for parameters of clinical interest, like percentiles and pixel indexes. To evaluate this we used data from a previous patient study on the dependence of histogram parameters on sample volume. With these data it is found that large interscanner differences in histogram parameters are possible for small values of V, as used in thin-section densitometry. For larger values of V, as required for a more adequate density resolution, the differences are much smaller and probably acceptable when compared to other sources of variability in lung densitometry. In conclusion, for sections of at least 2 mm and smooth reconstruction filters, corresponding to V > or = 8 mm3, the CT's nominal sample volume might be used for interscanner and interprotocol comparison of density resolution.
Pyrimidine-specific chemical reactions useful for DNA sequencing (1980)

Potassium permanganate reacts selectively with thymidine residues in DNA (1) while hydroxylamine hydrochloride at pH 6 specifically attacks cytosine (2). We have adopted these reactions for use with the chemical sequencing method developed by Maxam and Gilbert (3).
The design of server virtualization based video-wall control system (2012)

The video-wall, also called multi-vision, consists of multiple computer monitors, video projectors, or television sets tiled together contiguously or overlapped in order to form one large display. Typical display technologies include LCD panels, LED arrays, DLP tiles, and rear projection displays. Such a video wall system is used one for multi-screen advertising in the field of digital signage as well as one for n-screen service between the various terminals. It is also utilized as multi-screen for a surveillance control linked to CCTV. In this paper, we propose the video wall control system based on server virtualization. The proposed method expect as a solution for an usage of efficient resources of this system and one for processing system load evenly and one for synchronized video signal between each display as well.
Development of Wireless Control System for a Spherical Robot (2009)

The purpose of this thesis was to develop a control method which can reduce oscillation of lateral motion for a pendulum driven spherical robot operating on flat surface. The spherical robot provides a unique mobility and has several applications in surveillance and entertainment. Controlling a spherical robot is a challenging problem till today due to its nature of kinematics and dynamics. Firstly, its nonholonomic nature prohibits the use of conventional state feedback control laws. Secondly, kinematics of a spherical robot cannot be expressed as a chained-form system to utilize nonholonomic control algorithms. However, various types of nonlinear control algorithms were proposed to settle the problem though none of them provided satisfactory result. The kinematics and dynamics of the pendulum driven spherical robot was investigated followed by linearization for longitudinal and lateral motions through frequency and state space transformation. Moreover, the controllability of the states of the system was maintained during linearization. A robust self-tuning sliding mode con troller which suspends oscillation, maintains desired speed and compensates for unmodeled parameters was developed. The implemented control system consists of control station, prototype robot equipped with on-board microcontroller and sensors, and wireless communication link. Simulation and experimentation were conducted to test peformance of the control laws in suppressing oscillation and maintaining desired speed of the robot. The robot traveled to the commanded trajectory containing straight line and curve with relatively minimum oscillation at desired speed. Thus, the sliding mode control is an effective controller.
Infrared marker-based tracking in an indoor unknown environment for augmented reality applications (2009)

Marker based tracking requires complicated preparation work that impedes its use in augmented reality applications. This paper presents a novel tracking scheme to be used in an indoor unknown scene by adapting simultaneous localization and mapping (SLAM) algorithms. An infrared (IR) marker system is specifically designed to simplify the feature recognition and tracking in SLAM process. With one initial IR marker, the other markers can be projected randomly onto a large-area environment. The pose of camera can be estimated with a monocular IR camera in real time. Experimental result demonstrates that the proposed system meets the requirements of accuracy for large-area tracking. A prototype system is built to show its feasibility in unknown environment and potential use in applications.
[Effects of imidacloprid on arthropod community structure and its dynamics in alfalfa field]. (2007)

With species richness (S), individual number (N), Shannon's index (H') and evenness (E) as the indices of biodiversity, this paper studied the arthropod community structure and its seasonal dynamics in alfalfa field under effects of imidacloprid. The results showed that imidacloprid more affected the species number of natural enemies rather than that of insect pests, resulting in a significant increase of the dominance concentration of both total arthropod community and pest sub-community, but spraying the insecticide by the end of May had little effects on the dominance concentration of pollination bee sub-community. The numbers of dominant pests such as aphid and thrip reduced significantly at the initial stage of spraying imidacloprid, increased rapidly after 7 days, and exceeded the control after 40 days. As for the natural enemy sub-community, its species number decreased greatly and its species diversity and evenness were lower at the initial stage of spraying imidacloprid, its species number increased gradually after 7 days and approached to the level of the control thereafter, while its individual number was lower than the control all the time.
Reinnervation of cross-regenerated gustatory nerve fibers into amiloride-sensitive and amiloride-insensitive taste receptor cells (1998)

Single nerve fiber responses to NaCl and their inhibition by amiloride were compared among the chorda tympani (CT) and glossopharyngeal (IXth), and their cross-regenerated nerves in the C57BL/KsJ mice. The CT nerve innervating the anterior part of the tongue contained approximately equal numbers of two types of NaCl-responsive neurons; one type showed strong suppression of NaCl responses by amiloride [amiloride-sensitive (AS) type], and the other type showed only weak or no suppression of NaCl responses by amiloride [amiloride-insensitive (AI) type]. In contrast, the IXth nerve innervating the posterior part of the tongue has almost exclusively the AI type. This relative abundance of the AS and AI types of fibers was not altered by cross-regeneration of the two gustatory nerves into the reverse tongue regions. This suggests that regenerated taste axons selectively recouple with the appropriate type of receptor cell whether they innervate the front or the back of the tongue. Such selective synapse reformation may help explain the stability of response profiles of taste neurons during continual receptor cell turnover.
Coding mode determination by using fuzzy logic in H.264 motion estimation (2009)

Although exhaustively searching over all possible partition modes to choose the best coding mode for each macroblock improves the coding efficiency in H.264/AVC motion estimation, it has a lot of computational complexity. This paper proposes a fast algorithm to select the coding mode such that the number of candidate modes to be searched in motion estimation is significantly reduced and the coding picture quality is almost remained. The necessity of doing motion estimation in the current coding macroblock is determined by its previous corresponding macroblock information. If the motion estimation is necessary, fuzzy logic technique is used to classify the most appropriate mode for the motion estimation in H.264/AVC video coding. The simulation results show that the encoding time in the proposed algorithm is reduced to 55.7%~70% of the time searching for all coding modes exhaustively and the coded picture quality and bit rate are not influenced almost.
Increased Power Density via Variable Compression/Displacement And Turbocharging Using The Alvar-Cycle Engine (1998)

<div class="htmlview paragraph">This paper presents the analysis and design of a variable compression-ratio and displacement engine concept - the Alvar Cycle using a four-stroke engine-performance simulation. The Alvar-Cycle engine uses secondary pistons which reciprocate in auxiliary chambers housed in the cylinder head, at adjustable phase-angle differences from the primary pistons. The phase difference provides both the variable total engine displacement and compression ratio. Results indicate that the Alvar engine can operate at higher power density via a combination of higher intake boost and lower compression ratio to avoid knock at high loads, and capture the better thermal efficiency at higher compression ratios at part loads.</div>
Reduced Lodging for Soybean in Low Plant Population is Related to Light Quality (2001)

Lodging is a common production problem for soybean [ Glycine max (L.) Merr.] in the southeastern USA. Reducing plant height by planting at a low optimal population (plant population sufficient to optimize yield) is a recognized practice for reducing lodging. Environmental factors responsible for reduced plant height in response to low optimal population have not been determined, however. Plant height for determinate soybean is determined mainly during the vegetative period (emergence to R1). Because light quality affects stem extension, our objective was to determine the roles of red/far red light ratios and blue light irradiance during the vegetative period on plant height. Determinate cultivar Deltapine 3606 (Maturity Group VI) was planted at an optimal planting date during 1995 and 1996 at low (80 000 plants ha −1 ), medium (145 000 plants ha −1 ), and high (390000 plants ha −1 ) plant populations on a Commerce silt loam soil (fine‐silty, mixed, nonacid, thermic, Aeric, Fluvaquents) near Baton Rouge, LA (30°N Lat). Experimental design was a randomized complete block in a split plot arrangement with four replications. Plant populations were main plots and split plots were staked (non lodging) and unstaked (prone to lodging) treatments. Increased lodging in staked vs. unstaked plots resulted in a 10% yield loss. Across unstaked plots, decreased lodging in low vs. high population was associated with a 25% reduction in plant height and a 29% increase in main stem thickness. These morphological changes were more closely related to differences in red/far red light ratios for low vs. higher plant populations rather than to changes in blue light irradiance.
