Perspectives of Convertors and Communication Aspects in Automated Vehicles, Part 2: Printed Antennas and Sensors for Automotive Radars (2021)

Automated vehicles are becoming popular across the communities of e-transportation across the globe. Hybrid electric vehicles and autonomous vehicles have been subjected to critical research for decades. The research outcomes pertinent to this topic in the literature have been motivated by the industry and researchers to emphasize automated vehicles. Part 1 of this survey addressed the critical aspects that concern the bidirectional converter topologies and condition monitoring activities. In the present part, 24- and 77-GHz low-profile printed antennas are studied for automotive radar applications. These antennas are mounted on automated vehicles to avoid collision and are used for radio tracking applications. The present paper states the types of antenna structures, feed mechanisms, dielectric material requirements, design techniques, performance parameters, and challenges at 24- and 77-GHz resonating frequency applications. The recent developments in feed methodologies, beam scanning concepts, and the effect of sidelobe levels are addressed. Furthermore, the reasons behind the transition from 24 to 77 GHz are reported in detail. The recent advances in the application of various sensor schemes in an automated vehicle have also been discussed.
Product Correlator Performance for Gaussian Random Scenes (1974)

Contained herin is a derivation of two figures of merit for evaluating the performance of a product correlator and an associated discriminator curve. The general formulas are valid for both area and one-dimensional scenes. An explicit evaluation of the formulas is presented when the correlation functions are also Gaussian. In this case, the accuracy and probability of false match are found to take very simple forms.
Improved Packet Reordering Metrics (2008)

This document presents two improved metrics for packet reordering,
namely, Reorder Density (RD) and Reorder Buffer-occupancy Density
(RBD). A threshold is used to clearly define when a packet is
considered lost, to bound computational complexity at O(N), and to
keep the memory requirement for evaluation independent of N, where N
is the length of the packet sequence. RD is a comprehensive metric
that captures the characteristics of reordering, while RBD evaluates
the sequences from the point of view of recovery from reordering.
These metrics are simple to compute yet comprehensive in their
characterization of packet reordering. The measures are robust and
orthogonal to packet loss and duplication. This memo provides
information for the Internet community.

Unix systems programming for SVR4 (1996)

This book presents the details on how UNIX interacts with applications. If you're writing an application from scratch, or if you're porting an application to Solaris or to any other System V.4 platform, you may this book useful. It offers a complete explanation of all UNIX system calls and library routines to systems programming, working with I/O, files and directories, processing multiple input streams, file and record locking, and memory-mapped files. The reader will also learn about reading, printing, and setting the system time and date, determining who is logged in, and setting user and group ID. The book also shows how to change system configuration parameters for resource limits and how to create processes, job control, and signal handling. The work discusses interprocess communication, serial line characteristics, network programming with Berkeley sockets, Transport layer Interface (TLI), and the data link provider interface.
An approach to modeling and testing memories and its application to CAMs (2002)

An approach to modeling and testing memories is presented and illustrated using an n-word by l-bit (n/spl times/l) static content-addressable memory (GAM) array for cell input stuck-at faults. An input stuck at fault model for a CAM is defined, and a test of length 7n+2l+5 with 100% fault coverage with respect to this fault model is constructed. This test also detects all the usual cell stuck-at and transition faults. Finally, some design-for-testability (DFT) modifications facilitating a further reduction of this test's length are proposed.
A fuzzy approach towards perceptual classification and segmentation of MP3/AAC audio (2004)

The paper presents a novel perceptual based fuzzy approach towards classification and segmentation for MP3 and AAC audio in the compressed domain. The input audio is split into segments, which are classified as speech, music, fuzzy or silent. The proposed method minimizes critical errors of misclassification by fuzzy region modeling, thus increasing the efficiency of both pure and fuzzy classification. The experimental results show that the critical errors are minimized and the method is robust to capturing and encoding parameters of MP3 and AAC bit streams. Due to the efficiency obtained from fuzzy-region modeling and improved accuracy via rule-based semantic approach, the method is designed specifically for the audio-based multimedia indexing and retrieval systems.
Deep Learning Experiments with Skewed Data for Defect Prediction in Plastic Injection Molding (2018)

In this work, we investigate the possibility of predicting defects in plastic injection molding by learning predictive models from time-series process data collected from a molding machine. The model of our choice is an RNN (recursive neural network) model using LSTM (long short-term memory) units in its hidden layer. This model is well known as a deep learning model specialized for processing time-series data. Since defects are rare and thus the dataset is highly skewed, we try to achieve a high average recall rather than a high classification accuracy. We give some initial results of experiments and an outlook to the direction of our future works.
Tunable Networks from Thiolene Chemistry for Lithium Ion Conduction (2012)

End-functionalized poly(ethylene glycol) (PEG) and polydimethylsiloxane (PDMS) were cross-linked by a thiolene reaction with a tetra-functional thiol to create robust, tunable networks. These networks were loaded with increasing amounts of lithium bis(trifluoromethane sulfonyl imide) (LiTFSI), and their ion conductivity was measured. A wide range of salt loading was achieved, allowing the investigation of both salt-in-polymer and polymer-in-salt regimes. Thermal, mechanical, and ion conductivity properties of LiTFSI-loaded PEG and PEG-PDMS networks were measured. Even at high salt loadings, both networks maintained rubber-like characteristics, which were stable over a range of temperatures (30-90 °C). The PEG network with the highest salt loading showed the greatest ion conductivity, 6.7 × 10<sup>-4</sup> S cm<sup>-1</sup> at 30 °C, as measured by impedance spectroscopy. This system provides a route to optimize lithium ion conduction and mechanical properties.
Prospects for photovoltaic efficiency enhancement using low-dimensional structures (2000)

The use of photovoltaic solar cells provides an elegant way of converting sunlight to electricity. The photovoltaic industry is currently growing very rapidly, at a compounded rate of about 30% each year. Energy conversion efficiency is a key parameter with this technology since it directly impacts both material and deployment costs. The performance of the traditional bulk semiconductor solar cell is limited to about 33% while thermodynamic limits on the conversion of sunlight to electricity are much higher, at 93%. Low-dimensional structures appear capable of allowing much of this gap to be bridged. These structures allow increased flexibility with traditional efficiency enhancement approaches such as those based on `stacked' or tandem cells, which double efficiency limits to 68%. Perhaps more interestingly, they offer scope for completely new device concepts such as those relying on excitations between multiple energy bands and improved `hot-carrier' cells, that offer scope for similarly high performance.
The Pathogenesis of Equine Herpesvirus Type 1 in the Mouse: A New Model for Studying Host Responses to the Infection (1990)

An infection was established in adult BALB/c mice by means of intranasal inoculation of the AB4 strain of equine herpesvirus type 1 (EHV-1). The acute infection was confined to the respiratory tract and blood. Virus was shown to replicate in the nasal mucosa, trachea and lung for several days producing clinical signs of disease. Viraemia was also detected and a small proportion of peripheral blood cells contained virus at the peak of the infection. Histological and electron microscopic evidence were obtained which proved that productive virus replication occurred in the ciliated epithelial cells lining the bronchi and in pneumocytes in the lung, resulting in the destruction of these cells. Both humoral and cell-mediated responses to the infection were detected and monitored. By means of immunoprophylaxis or chemotherapy it was possible to modify the course of the infection. This infection model has many striking features in common with that observed in the natural host and the observations suggest that the mouse is a convenient and relevant model in which to study both host responses to EHV-1 infection and modification of the pathogenesis by means of immunoprophylaxis or therapy.
Sound velocity measurement based on optical heterodyne detection techniques using two successive ultrasonic waves (1973)

A new optical method for measuring the velocity of sound has been investigated; it is based essentially on optical heterodyne detection techniques using a pair of ultrasonic light modulators of slightly different frequency. A light beating signal can be easily generated from the frequency difference between these modulators if signal and reference light waves obtained from the first order dual diffraction spectrum are photomixed with each other. The only optical components are the two modulators, and their alignment is not critical to the generation of a stable beating signal. Since the beating signal includes the sound velocity in each modulator in its phase factor, the sound velocity is immediately measured by making use of a conventional electronic phasemeter.
Active picosecond optical pulse compression in semiconductor optical amplifiers (1999)

A novel technique is proposed to compress and amplify a weak picosecond optical pulse by utilizing a copropagating intense pump pulse in semiconductor optical amplifiers. It is shown that, simply by adjusting the time delay between the two pulses, a controlled compression of the pulsewidth by up to a factor of /spl sim/4 with pulse energy amplification of up to /spl sim/16 dB can be achieved simultaneously. Furthermore, a compressed pulse shape with strongly damped wings is also observed. The shortest achievable pulsewidth is demonstrated to be dependent on the frequency detuning and pump pulse properties.
Hirschman optimal transform DFT block LMS algorithm (2008)

In this paper a new block LMS algorithm is introduced. This algorithm is based on a fast HOT convolution developed by our group. We call our algorithm the block HOT-DFT LMS algorithm. Our algorithm uses the premise that the filter size is much smaller than the block size. Our developed algorithm is very similar to the block DFT LMS algorithm, but provides a reduced computational complexity of about 30%. The computational efficiency of the block HOT-DFT LMS algorithm is verified and its convergence analysis is analyzed.
Prenatal Diagnosis Using Fetal Cells From the Maternal Circulation (1997)

Current prenatal diagnosis relies on invasive methods such as amniocentesis and chorionic villus sampling. Because these methods carry a low, but finite risk of pregnancy loss, noninvasive genetic screening techniques are the focus of intense research. Isolating fetal cells from maternal blood for genetic analysis is the least invasive method currently being investigated. We discuss the various methods that have been used to isolate these cells. Nucleated red blood cells have emerged as the ideal fetal cell type. This is because they have the DNA material necessary for genetic analysis, they are consistently present in maternal blood, they can be easily identified based on their morphology, and they have a definite gestational life span.
Aloe-emodin suppresses prostate cancer by targeting the mTOR complex 2 (2012)

Phosphatidylinositol 3-kinase (PI3-K) amplification and phosphatase and tensin homolog (PTEN) deletion-caused Akt activation contribute to the development of prostate cancer. Mammalian target of rapamycin complex 2 (mTORC2) is a kinase complex comprised of mTOR, Rictor, mSin1, mLST8/GβL and PRR5 and functions in the phosphorylation of Akt at Ser473. Herein, we report that mTORC2 plays an important role in PC3 androgen refractory prostate cell proliferation and anchorage-independent growth. Aloe-emodin, a natural compound found in aloe, inhibited both proliferation and anchorage-independent growth of PC3 cells. Protein content analysis suggested that activation of the downstream substrates of mTORC2, Akt and PKCα, was inhibited by aloe-emodin treatment. Pull-down assay and in vitro kinase assay results indicated that aloe-emodin could bind with mTORC2 in cells and inhibit its kinase activity. Aloe-emodin also exhibited tumor suppression effects in vivo in an athymic nude mouse model. Collectively, our data suggest that mTORC2 plays an important role in prostate cancer development and aloe-emodin suppresses prostate cancer progression by targeting mTORC2.
A Low Power Fully-Integrated 76-81 GHz ADPLL for Automotive Radar Applications with 150 MHz/us FMCW Chirp Rate and -95dBc/Hz Phase Noise at 1 MHz Offset in FDSOI (2019)

In this paper, a fully integrated 76-81 GHz All Digital PLL for FMCW automotive radar applications is presented. It features a 20 GHz digital PLL followed by a 4x multiplier and buffer. The proposed ADPLL is implemented in a 22nm fully depleted SOI CMOS technology. It achieves up to 150 MHz/us FMCW chirp rate over a 4 GHz bandwidth and dissipates 85mW only.
Controlled Solubilization of Toluene by Silicate−Catanionic Surfactant Mesophases as Studied by in Situ and ex Situ XRD (2002)

Mesoscopically ordered silicate−surfactant composite materials of the M41S type synthesized in the presence of a swollen agent have been characterized by in situ and ex situ X-ray diffraction analysis. The key feature of the room-temperature synthesis is the use of a mixture of cationic and anionic surfactants as structure-directing agents. The lower interfacial charge density of the mixed surfactant aggregates stabilizes structures of lower interfacial curvature and therefore facilitates a more controlled solubilization of organic swelling agents. An increased solubilization capacity of the catanionic surfactant−silicate mesophase was observed close to an anionic/cationic surfactant ratio corresponding to a transition to the lamellar phase in the absence of toluene. In the presence of toluene, the catanionic template stabilizes microemulsion droplets that serve as building blocks for the final material. However, a fair amount of organic compound is solubilized in the silica−catanionic surfactant composite after the mesophase is formed. Although the present communication concerns mesoporous silica, the concept is a general one and may allow the synthesis of non-siliceous large-pore materials.
Catalyst (2016)

I'm a choreographer and I make performance installation. I am from a very small town on the Kenai Peninsula of Alaska. I'm Yup'ik on my father's side, and my Alaska family is from the Yukon-Kuskokwim Delta. I share this because it's where I'm from, and it's also where my work is from: the physical place of Alaska, and the confluence of my heritage and performance work.
High-throughput powder diffraction. I. A new approach to qualitative and quantitative powder diffraction pattern analysis using full pattern profiles (2004)

A new integrated approach to full powder diffraction pattern analysis is described. This new approach incorporates wavelet-based data pre-processing, non-parametric statistical tests for full-pattern matching, and singular value decomposition to extract quantitative phase information from mixtures. Every measured data point is used in both qualitative and quantitative analyses. The success of this new integrated approach is demonstrated through examples using several test data sets. The methods are incorporated within the commercial software program SNAP-1D , and can be extended to high-throughput powder diffraction experiments.
Protein Synthesis within Dendrites: Glycosylation of Newly Synthesized Proteins in Dendrites of Hippocampal Neurons in Culture (1996)

There is increasing evidence that certain mRNAs are present in dendrites and can be translated there. The present study uses two strategies to evaluate whether dendrites also possess the machinery for protein glycosylation. First, precursor labeling techniques were used to conjunction with autoradiography to visualize glycosyltransferase activities that are characteristic of the rough endoplasmic reticulum (RER) (mannose) or the Golgi apparatus (GA) (galactose and fucose) in dendrites that had been separated from their cell bodies and in intact neurons treated with brefeldin A or low temperature. Second, immunocytochemical techniques were used to define the subcellular distribution of proteins that are considered markers of the RER (ribophorin I) and GA (p58, alpha-mannosidase II, galactosyltransferase, and TGN38/41). Autoradiographic analysis revealed that isolated dendrites incorporated sugar precursors in a tunicamycin-sensitive and protein synthesis-dependent manner. Moreover, when intact neurons were pulse-labeled with 3H-labeled sugars at low temperature or after treatment with brefeldin A, labeling was distributed over proximal and sometimes distal dendrites. Immunolabeling for RER markers was predominantly localized in cell bodies but extended for a considerable distance into dendrites of all neurons. Immunolabeling for GA markers was confined to the cell body in approximately 70% of the neurons, but in 30% of the neurons, the staining extended into proximal and middle dendrites. These results indicate that the machinery for glycosylation extends well into dendrites in many neurons.
Multiple-Electron Transfer in a Single Step. Design and Synthesis of Highly Charged Cation-Radical Salts (2001)

[structure: see text]. Macromolecules 1c and 2c bearing multiple redox-active sites are synthesized by an efficient palladium-catalyzed coupling of 2,5-dimethoxytolylmagnesium bromide with readily available hexakis(4-bromophenyl)benzene and tetrakis(4-bromophenyl)methane. These macromolecular electron donors undergo reversible oxidation at a constant potential of 1.15 V vs SCE to yield robust, multiply charged cation radicals that are isolated in pure form using SbCl(5) as an oxidant. These nanometer-size cation-radical salts are shown to act as efficient "electron sponges" toward a variety of electron donors.
The complete nucleotide sequence of φCTX, a cytotoxin‐converting phage of <i>Pseudomonas aeruginosa</i>: implications for phage evolution and horizontal gene transfer via bacteriophages (1999)

phi CTX is a cytotoxin-converting phage isolated from Pseudomonas aeruginosa. In this study, we determined the complete nucleotide sequence of the phi CTX phage genome. The precise genome size was 35,538 bp with 21 base 5'-extruding cohesive ends. Forty-seven open reading frames (ORFs) were identified on the phi CTX genome, including two previously identified genes, ctx and int. Among them, 15 gene products were identified in the phage particle by protein microsequencing. The most striking feature of the phi CTX genome was an extensive homology with the coliphage P2 and P2-related phages; more than half of the ORFs (25 ORFs) had marked homology to P2 genes with 28.9-65.8% identity. The gene arrangement on the genome was also highly conserved for the two phages, although the G + C content and codon usage of most phi CTX genes were similar to those of the host P. aeruginosa chromosome. In addition, phi CTX was found to share several common features with P2, including the morphology, non-inducibility, use of lipopolysaccharide core oligosaccharide as receptor and Ca(2+)-dependent receptor binding. These findings indicate that phi CTX is a P2-like phage well adapted to P. aeruginosa, and provide clear evidence of the intergeneric spread and evolution of bacteriophages. Furthermore, comparative analysis of genome structures of phi CTX, P2 and other P2 relatives revealed the presence of several hot-spots where foreign DNAs, including the cytotoxin gene, were inserted. They appear to be deeply concerned in the acquisition of various genes that are horizontally transferred by bacteriophage infection.

Characterization of Clones of HIV‐1 Infected HuT 78 Cells Defective in <i>gag</i> Gene Processing and of SIV Clones Producing Large Amounts of Envelope Glycoprotein (1990)

Single‐cell clones of HIV‐1 (FRE‐3) or SIV/Mne infected HuT 78 cells were obtained by plating dilutions of virally infected HuT 78 cells on a monolayer of sheep choroid plexus cells in 96‐well microliter plates. Several of these clones produce HIV‐1 virus mutants that accumulate the gag precursor polyprotcin and lack a functional protease. These protease‐deficient viruses are non‐infectious and consist of aberrant “immature” virus particles as determined by electron microscopy. Several SIV mutants are also described that produce large amounts of either the envelope glycoprotein gp120 or the nucleic acid binding gag protein. These mutants are useful for the purification of these retroviral proteins, in developing assays of protease inhibitors, and in preparing SIV envelope protein vaccines.

Effect of Lipid Restriction on Mitochondrial Free Radical Production and Oxidative DNA Damage (2006)

Many studies have shown that caloric restriction (40%) decreases mitochondrial reactive oxygen species (ROS) generation in rodents. Moreover, we have recently found that 7 weeks of 40% protein restriction without strong caloric restriction also decreases ROS production in rat liver. This is interesting since it has been reported that protein restriction can also extend longevity in rodents. In the present study we have investigated the possible role of dietary lipids in the effects of caloric restriction on mitochondrial oxidative stress. Using semipurified diets, the ingestion of lipids in male Wistar rats was decreased by 40% below controls, while the other dietary components were ingested at exactly the same level as in animals fed ad libitum. After 7 weeks of treatment the liver mitochondria of lipid-restricted animals showed significant increases in oxygen consumption with complex I-linked substrates (pyruvate/malate and glutamate/malate). Neither mitochondrial H(2)O(2) production nor oxidative damage to mitochondrial or nuclear DNA was modified in lipid-restricted animals. Oxidative damage to mitochondrial DNA was one order of magnitude higher than that of nuclear DNA in both dietary groups. These results deny a role for lipids and reinforce the possible role of dietary proteins as being responsible for the decrease in mitochondrial ROS production and DNA damage in caloric restriction.
