Adrenal medullary and cortical blood flow during hemorrhage (1986)

We used a radiolabeled microsphere technique to measure adrenal medullary and cortical blood flow during hemorrhagic hypotension. Twenty pentobarbital-anesthetized, ventilated, adult mongrel dogs were bled into a pressurized bottle system to reduce and maintain mean arterial blood pressure at 100, 80, 60, or 40 mmHg (n = 5/group). Blood flow was measured prior to and 2, 5, 10, 15, and 25 min posthemorrhage. Adrenal medullary blood flow increased markedly (100-400%) at all levels of hemorrhage. In contrast, decreases in cortical blood flow were observed (approximately 50%) with hemorrhage to 80, 60, and 40 mmHg. Cortical blood flow returned to control levels at 25 min, except in the 40-mmHg group. Whole adrenal gland blood flow showed early, transient decreases, consistent with the fact that the adrenal cortex comprises the bulk of the gland, but it did not precisely reflect either cortical or medullary blood flow changes. Since this method for measuring adrenal medullary and cortical blood flow was developed for the current experiment, extensive evaluation of the technique was performed (n = 31 animals). These studies included demonstration that injection of 4 X 10(6) microspheres results in sufficient numbers of microspheres in the adrenal medulla and cortex to permit estimation of blood flow (greater than or equal to 400 spheres/sample), that 15-micron spheres are almost completely entrapped in the adrenal gland (greater than 98%), that multiple injections of microspheres (n = 5) do not alter blood flow, and that streaming of microspheres does not appear to occur to any significant extent in this vascular bed.(ABSTRACT TRUNCATED AT 250 WORDS)
Anaerobic Digestion of Raw and Thermally Hydrolyzed Wastewater Solids Under Various Operational Conditions (2011)

In this study, high-solids anaerobic digestion of thermally pretreated wastewater solids (THD) was compared with conventional mesophilic anaerobic digestion (MAD). Operational conditions, such as pretreatment temperature (150 to 170 degrees C), solids retention time (15 to 20 days), and digestion temperature (37 to 42 degrees C), were varied for the seven THD systems operated. Volatile solids reduction (VSR) by THD ranged from 56 to 62%, compared with approximately 50% for MAD. Higher VSR contributed to 24 to 59% increased biogas production (m3/kg VSR-d) from THD relative to MAD. The high-solids conditions of the THD feed resulted in high total ammonia-nitrogen (proportional to solids loading) and total alkalinity concentrations in excess of 14 g/L as calcium carbonate (CaCO3). Increased pH in THD reactors caused 5 to 8 times more un-ionized ammonia to be present than in MAD, and this likely led to inhibition of aceticlastic methanogens, resulting in accumulation of residual volatile fatty acids between 2 and 6 g/L as acetic acid. The THD produced biosolids cake that possessed low organic sulfur-based biosolids odor and dewatered to between 33 and 39% total solids. Dual conditioning with cationic polymer and ferric chloride was shown to be an effective strategy for mitigating dissolved organic nitrogen and UV-quenching compounds in the return stream following centrifugal dewatering of THD biosolids.
The NanoBox project: exploring fabrics of self-correcting logic blocks for high defect rate molecular device technologies (2004)

Trends indicate that emerging process technologies, including molecular computing, experiences an increase in the number of noise induced errors and device defects. In this paper, we introduce the NanoBox, a logic lookup table bit string. In this way, we contain and self-correct errors within the lookup table, thereby presenting a robust logic block to higher levels of logic design. We explore five different NanoBox coding techniques. We also examine the cost of implementing two different circuit blocks using a homogeneous fabric of NanoBox logic elements: 1) a floating point control unit from the IBM Power4 microprocessor and 2) a four-instruction ALU. In this initial investigation, our results are not meant to draw definitive conclusions about any specific NanoBox implementation, but rather to spur discussion and explore the feasibility of fine-grained error correction techniques in molecular computing systems.
Isothermal aging of IM7/8320 and IM7/5260 (1992)

Isothermal aging was conducted on two composite systems being considered as possible candidates for the next generation supersonic transport. The composite systems were IM7/5260, a carbon/thermoset, and IM7/8320, a carbon/amorphous thermoplastic. The materials were isothermally aged for a total of 5000 hours at 125 C and 175 C. These temperatures are approximately equivalent to the upper skin temperatures of an aircraft flying at Mach 2.0 and Mach 2.4, respectively. The variations of the following properties were determined as a function of aging time: weight loss, moduli, glass transition temperature, microcracking, and modulus and strength of a +/- 45 laminate. The difficulties and accuracy of strain measurements are also discussed.
Comparison of machine learned approaches for thyroid nodule characterization from shear wave elastography images (2018)

Various Computer Aided Diagnosis (CAD) systems have been developed that characterize thyroid nodules using the features extracted from the B-mode ultrasound images and Shear Wave Elastography images (SWE). These features, however, are not perfect predictors of malignancy. In other domains, deep learning techniques such as Convolutional Neural Networks (CNNs) have outperformed conventional feature extraction based machine learning approaches. In general, fully trained CNNs require substantial volumes of data, motivating several efforts to use transfer learning with pre-trained CNNs. In this context, we sought to compare the performance of conventional feature extraction, fully trained CNNs, and transfer learning based, pre-trained CNNs for the detection of thyroid malignancy from ultrasound images. We compared these approaches applied to a data set of 964 B-mode and SWE images from 165 patients. The data were divided into 80% training/validation and 20% testing data. The highest accuracies achieved on the testing data for the conventional feature extraction, fully trained CNN, and pre-trained CNN were 0.80, 0.75, and 0.83 respectively. In this application, classification using a pre-trained network yielded the best performance, potentially due to the relatively limited sample size and sub-optimal architecture for the fully trained CNN.
Anomalous conduction and ageing effects in rutile (TiO2) ceramics (1977)

Measurements are reported on the electrical conductivity of rutile ceramic capacitors subjected to a constant field of 105 V m-1. Provided the temperature exceeds a value of 130 degrees C the current is found to increase steadily with time, and this increase in conductivity is retained in the capacitor thus demonstrating an ageing effect. The existence of space charges near to the cathode and anode is established. That at the cathode appears to be associated with the anomalous increase in current and the ageing effect. The space charge rises from the migration of negative oxygen ions towards the anode, leaving behind a positive space charge at the cathode.

Lightweight Jammer Localization in Wireless Networks: System Design and Implementation (2009)

Jamming attacks have become prevalent during the last few years, due to the shared nature and the open access to the wireless medium. Finding the location of a jamming device is of great importance for restoring normal network operations. After detecting the malicious node we want to find its position, in order for further security actions to be taken. Our goal in this paper is the design and implementation of a simple, lightweight and generic localization algorithm. Our scheme is based on the principles of the gradient descent minimization algorithm. The key observation is that the packet delivery ratio (PDR) has lower values as we move closer to the jammer. Hence, the use of a gradient-based scheme, operating on the discrete plane of the network topology, can help locate the jamming device. The contributions of our work are the following: (a) we demonstrate, through analysis and experimentation, the way that the jamming effects propagate through the network in terms of the observed PDR. (b) we design a distributed, lightweight jammer localization system which does not require any modifications to the driver/firmware of commercial NICs. (c) We implement and evaluate our localization system on our 802.11 indoor testbed. An attractive and important feature of our system is that it does not rely on special hardware.
Ultrasonic Images - New Applications: Examples From Kalimantan (1994)

Abstract Recent developments have advanced ultrasonic technology to the point where images can be viewed which are similar in clarity to electrical imaging tools, bringing new applications to all wellbores. Ultrasonic high resolution images, previously known as borehole televiewers, have provided a breakthrough in borehole imaging, especially in oil-based muds. The Ultrasonic Borehole Imager (UBI#) tool measures both amplitude and transit time with peak-envelope processing techniques which provide an enhanced accuracy. Applications of the tool can be divided into two classifications, geologic and borehole deformation. Geologic applications consist of computation and analysis of structural and stratigraphic dips and thin bed analysis. Analysis of these images on a workstation allows the interactive computation of dipping features and a detailed depositional environment interpretation for reservoir delineation. High resolution thin bed analysis and cumulative sand count analysis in oil-base muds are possible by using an amplitude cut-off on a continuously computed median amplitude curve. These analyses are verified with integration and comparison of core data. Stress analysis and borehole deformation measurements are calculated from radius data. These measurements are accurate to better than .02 in diameter and less than 2° in azimuth orientation, allowing the calculation of minimum stress directions and various displays of borehole shapes. These displays make it possible to view and identify the various borehole deformation features such as key seat, borehole breakout, slippage, sloughing, and coal ledging.
Exploring a new transmission window for telecommunications in the 2 µm waveband (2016)

In this paper, we will demonstrate the possibility of opening a new telecommunications transmission window around the 2 µm wavelength, in order to exploit the potential low loss of hollow-core photonic bandgap fibers, with the benefits of significantly lower non-linearity and latency. We will show recent efforts developing a dense wavelength division multiplexing testbed at this waveband, with 100 GHz spacing wavelength channels and 105 Gbit/s total capacity achieved.
Isolation and identification of bacterial consortia responsible for degrading oil spills from the coastal area of Yanbu, Saudi Arabia (2015)

Twenty-three crude-oil-degrading bacteria were isolated from oil-contaminated sites near the Red Sea. Based on a high growth rate on crude oil and on hydrocarbon degradation ability, four strains were selected from the 23 isolated strains for further study. These four strains were selected on the basis of dichlorophenolindophenol assay. The nucleotide sequences of the 16S rRNA gene showed that these isolated strains belonged to genus Pseudomonas and Nitratireductor. Among the four isolates, strains S5 (Pseudomonas sp., 95%) and 4b (Nitratireductor sp., 70%) were the most effective ones in degrading crude oil. Using a spectrophotometer and gas chromatography–mass spectrometry, degradation of more than 90% of the crude oil was observed after two weeks of cultivation in Bushnell–Haas medium. The results showed that these strains have the ability to degrade crude oil and may be used for environmental remediation.
Restructuring a parallel simulation to improve cache behavior in a shared-memory multiprocessor (1993)

Synchronization is a significant cost in many parallel programs, and can be a major bottleneck if it is handled in a centralized fashion using traditional shared-memory constructs such as barriers. In a parallel time-stepped simulation, the use of global synchronization primitives limits scalability, increases the sensitivity to load imbalance, and reduces the potential for exploiting locality to improve cache behavior.
Novel technique for improving pattern placement in membrane mask making (1997)

Pattern placement errors pose a serious problem in the manufacture of masks for proximity x-ray lithography. Many of these errors are attributable to long term drifts in beam position relative to external fiducials. To address this problem we have developed a technique based on through-the-membrane monitoring of the electron beam position. This technique uses as a detector a reverse biased Schottky diode with high bandwidth and gain. In use this detector is mounted near the back surface of the membrane. An accurately patterned overlayer on the detector provides the fiducial reference. The overlayer is designed to modulate the electron-hole pair current generated in the diode by absorbing the incident beam. Position information is obtained by analyzing the image created from recording the digitized diode current during patterning. The phase in a Fourier transform of the data at the spatial frequency of the patterned absorber gives a measure of the position of the incident beam. Changes in the observed phase from one frame to the next can then be used to correct position errors of the beam in real time. We report results from tests of various components of this system. Initial results indicate that the system will be sufficiently fast and accurate for use in pattern placement correction for 130 nm ground rule mask production.
The Low Phytic Acid Phenotype in Soybean Line CX1834 Is Due to Mutations in Two Homologs of the Maize Low Phytic Acid Gene (2009)

Plant seeds accumulate phosphorus in the form of myo ‐inositol‐1,2,3,4,5,6‐hexa‐ kis phosphate, commonly referred to as phytic acid. Phytic acid is found complexed with cationic mineral species in the form of phytate, which is not well digested or absorbed by monogastric species such as humans, poultry, and swine. As a result, soybean [ Glycine max (L.) Merr.] has an effective deficiency of phosphorus and other minerals, despite high levels of minerals and phosphorus in the seed. Excreted phytate can also contribute to phosphorus contamination of groundwater and eutrophication of freshwater lakes and streams. In maize ( Zea mays L. ssp. mays ), a recessive mutation in a conserved region within the low phytic acid 1 ( lpa1 ) gene is responsible for the low phytic acid phenotype. We have identified recessive mutations in two soybean homologs of the maize lpa1 gene in soybean line CX1834, a mutagenized line with a low phytic acid phenotype. In three populations analyzed, we identified complete association between homozygosity for mutant alleles of the two lpa1 homologs and the low phytic acid phenotype in soybean. Molecular marker assays were designed that can be used to directly select for the mutant alleles that control the phenotype.
<title>Metabolic cytometry</title> (2000)

Capillary electrophoresis with laser-induced fluorescence detection has the potential to become an important tool in analyzing the chemical contents of single cells. Singe-cell studies are important for understanding the molecular mechanisms of many biological processes, including serious disorders, such as concern and neurodegradative diseases. We developed a new technique, Metabolic Cytometry, that allows us to study complex metabolic pathways in single cells. The essence of the technique is the following. A fluorescently labeled metabolic probe is introduce by incubation into a cell where it is converted to a number of fluorescently labeled metabolites. After incubation the cell is injected into the capillary and lysed. The metabolites are then separated and detected using CE-LIF. If metabolic cytometry is combined with image cytometry, then metabolic activities can be correlated with cellular phenotype or genotype. We applied this powerful approach to correlate glycosylation with the cell's phase in the cell cycle.

Stimulating Creativity with FunLines: A Case Study of Humor Generation in Headlines (2020)

Building datasets of creative text, such as humor, is quite challenging. We introduce Fun-Lines, a competitive game where players edit news headlines to make them funny, and where they rate the funniness of headlines edited by others. FunLines makes the humor generation process fun, interactive, collaborative, rewarding and educational, keeping players engaged and providing humor data at a very low cost compared to traditional crowdsourcing approaches. FunLines offers useful performance feedback, assisting players in getting better over time at generating and assessing humor, as our analysis shows. This helps to further increase the quality of the generated dataset. We show the effectiveness of this data by training humor classification models that outperform a previous benchmark, and we release this dataset to the public.
In Situ Temperature-Jump Dynamic Nuclear Polarization: Enhanced Sensitivity in Two Dimensional 13C−13C Correlation Spectroscopy in Solution (2008)

Dynamic nuclear polarization is combined with temperature-jump methods to develop a new 2D 13C-13C NMR experiment that yields a factor of 100-170 increase in sensitivity. The polaization step is performed at 100 K, and the sample is subsequently melted with a 10.6 microm laser pulse to yield a sample with highly polarized 13C spins. 13C detected 2D 13C-13C spectroscopy is performed in the usual manner.
