Integrating voice and data networks (2000)

Practical solutions for the world of packetized voice over data networks *Features in-depth solutions for the design and implementation of integrated voice and data networks *Detailed configurations show network engineers how to implement packetized voice immediately *Chapters on voice theory and data theory ensure mastery of fundamental knowledge *Learn how to lower costs, streamline your organization, prepare for new multimedia applications, and gain a competitive advantage by integrating your voice and data networks The integration of voice and data networks is creating a fundamental change in the telecommunications and data industries. This change means better phone service, lower prices, new features, less maintenance, and more choices, leading to a complete convergence of the data networking and telecommunications industries into a single community. With all this growth and change, network engineers and managers need specific information on how to integrate and configure packetized voice networks. Integrating Voice and Data Networks is the one reference manual you need to learn how to integrate traditional voice technology into existing Cisco data networks.Integrating Voice and Data Networks is both a conceptual reference and a practical how-to book that bridges the gap between existing telephony networks and the new world of packetized voice over data networks. Underlying technologies are explained in a non-product-specific manner that gives a holistic understanding of voice/data integration. You'll then follow a complete process to design and implement a variety of network scenarios, leveraging author Scott Keagy's extensive experience with real voice/data networks. Integrating Voice and Data Networks focuses on the implementation of Voice over Frame Relay (VoFR), Voice over ATM (VoATM), and Voice over IP (VoIP) using Cisco IOS(r) voice gateways, including the Cisco MC3810, Cisco 2600/3600/7200/7500 series routers, and Cisco AS5300/AS5800 access servers.

Cost-Sensitive Learning of Deep Feature Representations From Imbalanced Data (2017)

Class imbalance is a common problem in the case of real-world object detection and classification tasks. Data of some classes are abundant, making them an overrepresented majority, and data of other classes are scarce, making them an underrepresented minority. This imbalance makes it challenging for a classifier to appropriately learn the discriminating boundaries of the majority and minority classes. In this paper, we propose a cost-sensitive (CoSen) deep neural network, which can automatically learn robust feature representations for both the majority and minority classes. During training, our learning procedure jointly optimizes the class-dependent costs and the neural network parameters. The proposed approach is applicable to both binary and multiclass problems without any modification. Moreover, as opposed to data-level approaches, we do not alter the original data distribution, which results in a lower computational cost during the training process. We report the results of our experiments on six major image classification data sets and show that the proposed approach significantly outperforms the baseline algorithms. Comparisons with popular data sampling techniques and CoSen classifiers demonstrate the superior performance of our proposed method.

Synthesis, structure and density functional study of the ansa-rhenocene complex [Re{(η-C5H4)CMe2(η-C5H4)}Cl] † (2000)

The ansa-rhenocene compound [Re{(η-C5H4)CMe2(η-C5H4)}Cl] 1 has been prepared by reaction of ReCl5 with [K2(C5H4)CMe2(C5H4)]. X-Ray crystallography shows the molecular structure to be unsymmetrical, with the angle defined by the Re-bridgehead carbon vector and the chlorine atom found to be 170.4°. A density functional study compares the electronic structure of [Re{(η-C5H4)CH2(η-C5H4)}Cl] with [Re{(η-C5H5)2Cl] and shows that for the ansa-bridged species, the chlorine binds less effectively in the central position. The calculated structure of [Re{(η-C5H4)CH2(η-C5H4)}Cl] is also found to be unsymmetrical.

Agreement Tracking for Multi-Issue Negotiation Dialogues (2023)

Automated negotiation support systems aim to help human negotiators reach more favorable outcomes in multi-issue negotiations (e.g., an employer and a candidate negotiating over issues such as salary, hours, and promotions before a job offer). To be successful, these systems must accurately track agreements reached by participants in real-time. Existing approaches either focus on task-oriented dialogues or produce unstructured outputs, rendering them unsuitable for this objective. Our work introduces the novel task of agreement tracking for two-party multi-issue negotiations, which requires continuous monitoring of agreements within a structured state space. To address the scarcity of annotated corpora with realistic multi-issue negotiation dialogues, we use GPT-3 to build GPT-Negochat, a synthesized dataset that we make publicly available. We present a strong initial baseline for our task by transfer-learning a T5 model trained on the MultiWOZ 2.4 corpus. Pre-training T5-small and T5-base on MultiWOZ 2.4's DST task enhances results by 21% and 9% respectively over training solely on GPT-Negochat. We validate our method's sample-efficiency via smaller training subset experiments. By releasing GPT-Negochat and our baseline models, we aim to encourage further research in multi-issue negotiation dialogue agreement tracking.
Injectable particulate contraceptive systems. (1980)

The systems-engineering approach to delivery of long-term contraception can involve the use of matrix devices for contraceptive steroids from which the steroid is released at a controlled rate over a prolonged period of time after a single administration. The concept of system design principles in contraceptive delivery is explained. In 1973 WHO organized a task force on long-acting systemic agents for fertility regulation. This is the report on a WHO-sponsored project to incorporate the basic design principles of a long-acting system into the design of an injectable particulate contraceptive system. The initial requirements included: 1) provision by a single administration of continuous controlled release of NET (norethisterone) for at least 6 months; 2) injection-administered carrier; 3) biodegradable carrier; 4) no carrier-induced side effects at the site of the injections; 5) complete disappearance of all components from the injection site; 6) a flexible system as to dose and duration to accommodate individual needs; and 7) reversibility of treatment. Experimental data so far satisfy the 1st 6 requirements. The injectable particulate system cannot be made reversible. Aspects for future research in this area are mentioned.
Selected α-pyrones from the plants Cryptocarya novoguineensis (Lauraceae) and Piper methysticum (Piperaceae) with activity against Haemonchus contortus in vitro (2019)

Due to the widespread occurrence and spread of anthelmintic resistance, there is a need to develop new drugs against resistant parasitic nematodes of livestock animals. The Nobel Prize-winning discovery and development of the anti-parasitic drugs avermectin and artemisinin has renewed the interest in exploring natural products as anthelmintics. In the present study, we screened 7500 plant extracts for in vitro-activity against the barber's pole worm, Haemonchus contortus, a highly significant pathogen of ruminants. The anthelmintic extracts from two plants, Cryptocarya novoguineensis and Piper methysticum, were fractionated by high-performance liquid chromatography (HPLC). Subsequently, compounds were purified from fractions with significant biological activity. Four α-pyrones, namely goniothalamin (GNT), dihydrokavain (DHK), desmethoxyyangonin (DMY) and yangonin (YGN), were purified from fractions from the two plants, GNT from C. novoguineensis, and DHK, DMY and YGN (= kavalactones) from P. methysticum. The three kavalactones induced a lethal, eviscerated (Evi) phenotype in treated exsheathed third-stage larvae (xL3s), and DMY and YGN had moderate potencies (IC<sub>50</sub> values of 31.7 ± 0.23 μM and 23.7 ± 2.05 μM, respectively) at inhibiting the development of xL3s to fourth-stage larvae (L4s). Although GNT had limited potency (IC<sub>50</sub> of 200-300 μM) at inhibiting L4 development, it was the only compound that reduced L4 motility (IC<sub>50</sub> of 6.25-12.50 μM). The compounds purified from each plant affected H. contortus in an irreversible manner. These findings suggest that structure-activity relationship studies of α-pyrones should be pursued to assess their potential as anthelmintics.
Mine Support, Radiation and Ventilation Control with Spray-on Barriers (1993)

The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation. Several agent materials have been assessed for use in underground excavation support situations, with optimal performance being shown by a polyurethane-based composition designated Mineguard TM by its developer. In addition to demonstrating exceptional rock support capabilities, this material has also been shown to be capable of significantly reducing levels of radon flux and diffusion flow occurring from highly emanating source environments. The radon impermeability characteristics of Mineguard TM offers potential for its use in creating effective barriers to naturally-occurring radon flows which typically develop both in underground uranium and non-uranium mines. Laboratory ventilation investigations have also provided detailed information concerning Mineguard TM material friction factor, surface roughness and airflow resistance characteristics. The evaluation of friction factor conditions was used to determine potential power and ventilation cost reduction capabilities possible to be achieved when airways may be lined with such spray-on barrier materials.

Robust Energy Management for Microgrids With High-Penetration Renewables (2013)

Due to its reduced communication overhead and robustness to failures, distributed energy management is of paramount importance in smart grids, especially in microgrids, which feature distributed generation (DG) and distributed storage (DS). Distributed economic dispatch for a microgrid with high renewable energy penetration and demand-side management operating in grid-connected mode is considered in this paper. To address the intrinsically stochastic availability of renewable energy sources (RES), a novel power scheduling approach is introduced. The approach involves the actual renewable energy as well as the energy traded with the main grid, so that the supply-demand balance is maintained. The optimal scheduling strategy minimizes the microgrid net cost, which includes DG and DS costs, utility of dispatchable loads, and worst-case transaction cost stemming from the uncertainty in RES. Leveraging the dual decomposition, the optimization problem formulated is solved in a distributed fashion by the local controllers of DG, DS, and dispatchable loads. Numerical results are reported to corroborate the effectiveness of the novel approach.
Parallelized multi–graphics processing unit framework for high-speed Gabor-domain optical coherence microscopy (2014)

Gabor-domain optical coherence microscopy (GD-OCM) is a volumetric high-resolution technique capable of acquiring three-dimensional (3-D) skin images with histological resolution. Real-time image processing is needed to enable GD-OCM imaging in a clinical setting. We present a parallelized and scalable multi-graphics processing unit (GPU) computing framework for real-time GD-OCM image processing. A parallelized control mechanism was developed to individually assign computation tasks to each of the GPUs. For each GPU, the optimal number of amplitude-scans (A-scans) to be processed in parallel was selected to maximize GPU memory usage and core throughput. We investigated five computing architectures for computational speed-up in processing 1000×1000 A-scans. The proposed parallelized multi-GPU computing framework enables processing at a computational speed faster than the GD-OCM image acquisition, thereby facilitating high-speed GD-OCM imaging in a clinical setting. Using two parallelized GPUs, the image processing of a 1×1×0.6 mm3 skin sample was performed in about 13 s, and the performance was benchmarked at 6.5 s with four GPUs. This work thus demonstrates that 3-D GD-OCM data may be displayed in real-time to the examiner using parallelized GPU processing.
Central nervous system involvement in early syphilis. Part II. Correlation between auditory brain stem responses (ABR) and cerebrospinal fluid abnormalities (1983)

Twenty-six consecutive patients with secondary or early latent syphilis, all with normal neurological findings, were studied with auditory brainstem responses (ABR), cerebrospinal fluid (CSF) analysis and an assay for immune complexes in serum and CSF. Seven of the 26 patients studied had a pathological ABR pattern and 14 had one or more pathological CSF tests. Fifteen patients had circulating immune complexes in serum. No patient had demonstrable immune complexes in CSF. A significant correlation was found between an abnormal ABR pattern and pathological CSF findings--but not between pathological ABR and presence of immune complexes. ABR seems to be a sensitive method for detection of early asymptomatic CNS involvement in syphilis.

Vessel extraction techniques and algorithms: a survey (2003)

Vessel segmentation algorithms are critical components of circulatory blood vessel analysis systems. We present a survey of vessel extraction techniques and algorithms, putting the various approaches and techniques in perspective by means of a classification of the existing research. While we target mainly the extraction of blood vessels, neurovascular structure in particular we also review some of the segmentation methods for the tubular objects that show similar characteristics to vessels. We divide vessel segmentation algorithms and techniques into six main categories: (1) pattern recognition techniques, (2) model-based approaches, (3) tracking-based approaches, (4) artificial intelligence-based approaches, (5) neural network-based approaches, and (6) miscellaneous tube-like object detection approaches. Some of these categories are further divided into sub-categories. A table compares the papers against such criteria as dimensionality, input type, preprocessing, user interaction, and result type.
OPTN p.Met468Arg and ATXN2 intermediate length polyQ extension in families with C9orf72 mediated amyotrophic lateral sclerosis and frontotemporal dementia (2017)

We have ascertained two families affected with familial amyotrophic lateral sclerosis (ALS) in which they both carry a hexanucleotide repeat expansion in the C9orf72 gene, specifically in individuals who also presented with frontotemporal dementia (FTD) or behavioral variant FTD (bvFTD). While some reports attribute this phenotypic heterogeneity to the C9orf72 expansion alone, we screened for additional genetic variation in known ALS-FTD genes that may also contribute to or modify the phenotypes. We performed genetic testing consisting of C9orf72 hexanucleotide expansion, ATXN2 polyglutamine (polyQ) expansion, and targeted next generation sequencing using the ONDRISeq, a gene panel consisting of 80 genes known to be associated with neurodegenerative diseases such as ALS, FTD, Alzheimer's disease, Parkinson's disease, and vascular cognitive impairment. In addition to the C9orf72 expansion, we observed an ATXN2 polyQ intermediate length expansion, and OPTN p.Met468Arg in patients who exhibited ALS and FTD or bvFTD. We conclude that the C9orf72 expansion likely explains much of the ALS-FTD phenotype; however, inheritance of these additional variants likely modifies the disease course and may provide further evidence for biologically relevant oligogenic inheritance in ALS.
Free-Piston Stirling Engine Technologies and Models: A Review (2021)

The Stirling engine is an alternative solution to produce cleaner energy in order to achieve the reduction of the fossil fuel consumption and the CO2 emissions. It comprises an external combustion engine that can convert any external heat source into mechanical power, through cyclic expansion and compression of a working gas in a closed-regenerative cycle, with or without driving mechanisms. The free-piston Stirling Engine is significantly preferred because of the absence of any mechanical linkage resulting in longer operating life, lower noise pollution, maintenance and vibration free, self-starting and high thermal efficiency. The aim of this paper is to summarize the research works on the free-piston Stirling engine technologies and models. First, the working principles of the free-piston Stirling engine are described, identifying different configurations. Then, several applications are presented. Finally, a detailed review of the models available in literature is given, pointing out the main assumptions and equations.
Characterization of two genes encoding Bacillus thuringiensis insecticidal crystal proteins toxic to Coleoptera species (1992)

Bacillus thuringiensis EG2838 and EG4961 are highly toxic to Colorado potato beetle larvae, and only strain EG4961 is toxic to southern corn rootworm larvae. To investigate the cause of the different insecticidal activities of EG2838 and EG4961, cryIII-type genes toxic to coleopterans were cloned from each strain. The cryIIIB gene, cloned as part of an 8.0-kb EcoRI fragment of EG2838 DNA, encoded a crystal protein (CryIIIB) of 74,237 Da. The cryIIIB2 gene, cloned as part of an 8.3-kb PstI-Asp718 fragment of EG4961 DNA, encoded a crystal protein (CryIIIB2) of 74,393 Da that was 94% identical to CryIIIB. Analysis of the transcriptional start sites showed that cryIIIB and cryIIIB2 were initiated from a conserved region located within 130 nucleotides upstream from the translation start sites of both genes. Although the CryIIIB and CryIIIB2 proteins were similar in sequence, they displayed distinct insecticidal activities: CryIIIB was one-third as toxic as CryIIIB2 to Colorado potato beetle larvae, and CryIIIB2, but not CryIIIB, was toxic to southern corn rootworm larvae. Genes encoding crystal proteins of approximately 32 and 31 kDa were located adjacent to the cryIIIB and cryIIIB2 genes, respectively. The 32- and 31-kDa crystal proteins failed to enhance the insecticidal activities of CryIIIB and CryIIIB2.
Structural and Optoelectronic Characterization of RF Sputtered ZnSnN2 (Adv. Mater. 18/2013) (2013)

The development of earth-abundant semiconductors is an important step in working towards the realization of photovoltaic production on a global scale. On page 2562, Harry A. Atwater and co-workers successfully synthesize stoichiometric ZnSnN2, a new earth-abundant semiconductor material, which has a theoretical direct band gap of 1.42 eV, making it well suited for potential applications in thin film photovoltaics.
