Pests of Monocotyledon Crops (1992)

During the long and complex evolution of maize, periodic mutations produced kernels with endosperms containing high concentrations of sugars. Selection and cultivation of the resulting sweet genotypes eventually led to the product now known as sweet corn, sweet maize or vegetable corn. The sweetness of Zea mays var. rugosa L. is controlled by a number of recessive genes that also aid in the broad classification of sweet corn cultivars: e.g. su, the standard sweet corns; se, corns with enhanced sweetness; and sh 2 , the recently developed 'super sweets'. The two latter types maintain sweetness, and therefore quality, far longer than the standard sus. Although a warm-season, annual crop, and susceptible to frost, sweet corn can be grown in areas having relatively short growing seasons because the edible portion is harvested and consumed prior to physiological maturity. It is grown world-wide for fresh-market consumption and for processing (canned, frozen cut corn and frozen whole ears). The roots, stems, foliage and fruits are attacked by a number of vertebrate and invertebrate pests, as well as many diseases. Home gardeners may accept a great deal of damage from insects, but for commercial purposes, insect-related factors such as feeding on the kernels, insect by-products, or the actual presence of insects or insect parts, may reduce marketability. Because it affects customer appeal, superficial or 'cosmetic' injury to the
Evidence for, and Importance of, cGMP-Independent Mechanisms with NO and NO Donors on Blood Vessels and Platelets (2005)

In the vasculature it is well established that cGMP is involved in the relaxant response to nitric oxide (NO) and NO donors. However, there is an increasing evidence that alternative/additional pathways that are cGMP-independent may also exist. A key criterion for a response to NO or a NO donor drug to be classified as cGMP-independent is lack of (or incomplete) inhibition by the selective inhibitor of soluble guanylate cyclase, ODQ (1H-[1,2,4]oxadiazole[4,3-a]quinoxalin-1-one). In many blood vessels cGMP-independent mechanisms contribute to the vasorelaxation, and in certain vascular beds cGMP-independent relaxation may be the predominant mechanism of action of NO and NO donors. NO donor drugs that generate NO "spontaneously", like authentic NO (i.e. solutions of NO gas), appear to exhibit a larger component of cGMP-independent vasorelaxation than do those drugs that require bioactivation in the tissue. The long lasting inhibition of responses to vasoconstrictors by S-nitrosothiols, persisting after removal of these NO donors, may be a cGMP-independent process, at least in some vessels. The mechanisms involved in the inhibition of vascular growth by NO and NO donors are predominantly cGMP-independent, as are the mechanisms responsible for the effects of NO donors on apoptosis in vascular smooth muscle and endothelial cells. The ability of NO and NO donors to inhibit platelet aggregation has a significant cGMP-independent component. cGMP-independent pathways are most often, though not exclusively, seen at high concentrations (microM - mM) of NO and NO donors. Hence, in relation to the actions of endogenous NO, these pathways may be particularly important in settings when the inducible isoform of NO-synthase is expressed. Furthermore, cGMP-independent pathways are enhanced in animal models of atherosclerosis and ischaemia. This suggests that it may be possible to target cGMP-independent mechanisms with selected NO donors in disease states.
Traversal optimizations and analysis for large graph clustering (2015)

Graph is an extremely versatile data structure in terms of its expressiveness and flexibility to model a range of real life phenomenon, such as social, biological, sensor, and computer networks. Finding groups of vertices based on their similarity is the fundamental graph mining task to get useful insights. The existing methods suffer from scalability issues due to enormous computations of an exact similarity estimation. Therefore, we introduce Collaborative Similarity Measure (CSM) based on shortest path strategy, instead of all paths, to define structural and semantic relevance among vertices efficiently. We evaluate this measure for personalized email community detection as an application scenario. However, an abundance of structural information has resulted in non-trivial graph traversals. Shortcut construction is among the utilized techniques implemented for efficient shortest path (SP) traversals on graphs. The shortcut construction, being a computationally intensive task, required to be exclusive and offline, often produces unnecessary auxiliary data. To overcome this issue, we present Shortest Path Overlapped Region (SPORE), a performance-based initiative that improves the shortcut construction performance by exploiting SP overlapped regions. Path overlapping with empirical analysis has been overlooked by shortcut construction systems. SPORE avails this opportunity and provides a solution by constructing auxiliary shortcuts incrementally, using SP trees during traversals, instead of an exclusive step. SPORE is exposed to a graph clustering task, which requires extensive graph traversals to group similar vertices together, for realistic implications. We further suggest an optimization strategy to accelerate the performance of the clustering process using confined subgraph traversals. Leveraging the SPORE with multiple SP computations consistently reduces the latency of the entire clustering process. A parameter-free graph clustering with scalable graph traversal strategy for a billion scale graph remain an open issue.
Derivatization-High Performance Liquid Chromatographic Determination of Methanol in Human Plasma (1997)

Abstract A simple and sensitive high performance liquid chromatographic method is described for the determination of methanol in human plasma, as a highly sensitive derivative. The methanol, spiked in plasma, after simple ultrafiltration treatment, was derivatized with 3-bromomethyl-7-methoxy-1,4-benzoxazin-2-one in a heterogeneous system, using benzalkonium chloride as phase transfer catalyst. The resulting derivative was chromatographed on a LiChrospher diol column with n-hexane:dichloromethane (9:1, v/v) as the mobile phase and 1-nitronaphthalene as the internal standard. The HPLC system showed good selectivity for methanol determination. Several parameters affecting the derivatization of methanol extracted from spiked plasma were investigated. The linear range for the determination of methanol in spiked human plasma was over 1–10 μmol/mL; the detection limit (signal to noise = 5, sample size 10 μL) of methanol was about 0.06 ± 0.02 μmol/mL. The intraday relative standard deviation (n = 6) and the interday relative standard deviation (n = 8) were all below 5%. Recovery of methanol in spiked human plasma was greater than 98%.
Prevalence, Biogenesis, and Functionality of the Serine Protease Autotransporter EspP (2012)

Enterohemorrhagic E. coli (EHEC) causes severe diseases in humans worldwide. One of its virulence factors is EspP, which belongs to the serine protease autotransporters of Enterobacteriaceae (SPATE) family. In this review we recapitulate the current data on prevalence, biogenesis, structural properties and functionality. EspP has been used to investigate mechanistic details of autotransport, and recent studies indicate that this transport mechanism is not autonomous but rather dependent on additional factors. Currently, five subtypes have been identified (EspPα-EspPε), with EspPα being associated with highly virulent EHEC serotypes and isolates from patients with severe disease. EspPα has been shown to degrade major proteins of the complement cascade, namely C3 and C5 and probably interferes with hemostasis by cleavage of coagulation factor V. Furthermore, EspPα is believed to contribute to biofilm formation perhaps by polymerization to rope-like structures. Together with the proteolytic activity, EspPα might ameliorate host colonization and interfere with host response.
Cortical Activation Induced by Intraoral Stimulation with Water in Humans (2000)

Studies of gustatory processing frequently utilize water as a control stimulus. However, the neural representations of intraoral stimulation with water have received little attention. We report a series of positron emission tomography studies involving intraoral stimulation with deionized distilled water. Attempting to taste water produced large, bilateral activations in insular, opercular, Rolandic and cerebellar cortices relative to resting with eyes closed or 'smelling' odorless air. The magnitude and volume of activation was substantially reduced when tasting water was contrasted with voluntary swallowing. This indicates that much of the activity induced by water reflects intraoral somatosensory or motor processing. Nevertheless, portions of the insula, operculum, post-central gyrus and cerebellum remained significantly activated in the contrast between 'tasting' water and swallowing. This activity appears to represent a specific neural correlate of fluid stimulation, and may reflect aspects of trigeminal, gustatory or thermal coding. These findings emphasize the large volume of cortex dedicated to intraoral processing, and highlight the importance of controlling for nongustatory factors in studies of gustation.
Proliferative response of immune mouse T-lymphocytes to the lymphocytosis-promoting factor of Bordetella pertussis (1984)

Immunization of mice with a whole-cell pertussis vaccine or with the purified, detoxified lymphocytosis-promoting factor (LPF) of Bordetella pertussis resulted in an increased in vitro proliferative response to LPF in immune lymph node cells. The proliferative response was detected above the nonspecific mitogenic activity of LPF. That the proliferative response of the immune lymph node cells was a demonstration of a specific cell-mediated immunity to LPF was supported by the following: (i) the specificity of the response to the immunizing antigen; (ii) the ability of chemically modified, nonmitogenic LPF to induce proliferation in immune lymph node cells; and (iii) a dependence on T-cells for the demonstration of the proliferative response of immune cells to LPF. Immunization of mice with protective doses of detoxified LPF resulted in serum antibody and cell-mediated responses to LPF. Immunization of mice with protective doses of whole-cell pertussis vaccine resulted in a cell-mediated response but not a detectable antibody response to LPF. The LPF of B. pertussis is believed to play an important role in pathogenesis and immunity in pertussis, and the demonstration of a cell-mediated immune response to LPF suggests a possible role for cell-mediated immunity to LPF in protection from pertussis disease.
Prevention of High-Altitude Pulmonary Edema by Nifedipine (1991)

The prophylactic administration of nifedipine is effective in lowering pulmonary-artery pressure and preventing high-altitude pulmonary edema in susceptible subjects. These findings support the concept that high pulmonary-artery pressure has an important role in the development of high-altitude pulmonary edema.
A Context Broker for Building Smart Meeting Rooms (2004)

Building smart meeting rooms requires the support of a computing system architecture. In this paper, we describe the Context Broker Architecture (CoBrA), a broker-centric agent architecture for pervasive contextaware systems. CoBrA exploits theWeb Ontology Language OWL for supporting knowledge sharing and data fusion, uses logic inferences for resolving and detecting inconsistent context knowledge, and provides users with a policy language to control their private information. Central to CoBrA is an intelligent broker agent that maintains a share model of context for all agents, services, and devices in the space, and protects users’ privacy by enforcing the policy rules that they have defined. We also describe the use of CoBrA ontologies, context reasoning mechanisms, and privacy protection in a smart meeting room system called EasyMeeting.
Genes, enzymes and chemicals of terpenoid diversity in the constitutive and induced defence of conifers against insects and pathogens* (2006)

Insects select their hosts, but trees cannot select which herbivores will feed upon them. Thus, as long-lived stationary organisms, conifers must resist the onslaught of varying and multiple attackers over their lifetime. Arguably, the greatest threats to conifers are herbivorous insects and their associated pathogens. Insects such as bark beetles, stem- and wood-boring insects, shoot-feeding weevils, and foliage-feeding budworms and sawflies are among the most devastating pests of conifer forests. Conifer trees produce a great diversity of compounds, such as an enormous array of terpenoids and phenolics, that may impart resistance to a variety of herbivores and microorganisms. Insects have evolved to specialize in resistance to these chemicals -- choosing, feeding upon, and colonizing hosts they perceive to be best suited to reproduction. This review focuses on the plant-insect interactions mediated by conifer-produced terpenoids. To understand the role of terpenoids in conifer-insect interactions, we must understand how conifers produce the wide diversity of terpenoids, as well as understand how these specific compounds affect insect behaviour and physiology. This review examines what chemicals are produced, the genes and proteins involved in their biosynthesis, how they work, and how they are regulated. It also examines how insects and their associated pathogens interact with, elicit, and are affected by conifer-produced terpenoids.
Potential benefits of free-form optics in on-axis imaging applications with high aspect ratio (2013)

Including free-form optical components in imaging systems provides numerous opportunities for enhanced performance and compact, lightweight packaging. This applies especially to the use of free-form optics in off-axis imaging applications. In case of on-axis imaging, rotationally symmetric lenses are typically used, as they greatly simplify the design and manufacturing process. However, for imaging applications with high aspect ratio, free-form optics can help to provide solutions with clearly better overall imaging performance. For such cases, the ray tracing simulations in this work demonstrate superior imaging performance of basic free-form lenses in comparison to conventional rotationally symmetric lenses, each consisting of two surfaces.

A Study on Voltage Reference Buffers for Low Voltage Switched Capacitor Data Converters (2006)

Voltage reference buffers published in recent years for application to low-voltage switched-capacitor data converters are analyzed and compared in terms of power efficiency, settling behavior and power supply rejection. Design trade-offs are discussed. A novel switched-capacitor biased voltage reference buffer which is ideal for over- sampling ADCs is proposed and analyzed. This novel structure combines power efficiency, stability in settling, and high PSRR in low frequency.
Hydrogel coatings for artificial heart implants (2011)

Polyurethanes (PU) are nowadays one of the most widely used types of polymers for biomedical applications. Th e segmented nature of these materials enables to obtain both fl exibility and mechanical strength within the same material. However, there is a need to modify a surface of PU in order to produce highly hemocompatible materials that can be used in fabrication of permanent blood-contacting devices such as vascular implants, valves or hearts. Among many types of modifi cations, hydrogel coating appears to be very promising. Such modifi cation increases the hydrophilicity of PU which in turn causes an increase in the bioand hemocompatibility of the material. Th e aim of presented study was to create a polyvinylpyrrolidone (PVP) hydrogel coating onto a surface of polyurethane. A possibility of using a free radical polymerization reaction was investigated. Th e obtained materials were analyzed in terms of durability, swelling ratio and contact angle. Th e FTIR-ATR analysis confi rmed that polyurethane surfaces have been successfully coated with PVP.
Performance of chromID ESBL, a chromogenic medium for detection of Enterobacteriaceae producing extended-spectrum β-lactamases (2008)

The chromogenic agar medium chromID ESBL (bioMérieux) was compared with BLSE agar medium (AES) for selective isolation and presumptive identification of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae from clinical samples. A total of 765 samples (468 rectal swabs, 255 urine samples and 42 pulmonary aspirations) obtained from 547 patients was processed. All bacterial strains isolated on either medium were further characterized using biochemical tests, and ESBL producers were confirmed by synergy testing. Genetic characterization of ESBL genes was determined by PCR. A total of 33 ESBL-producing Enterobacteriaceae strains [Escherichia coli (n=16), Klebsiella pneumoniae (n=8), Enterobacter spp. (n=3), Citrobacter spp. (n=5) and Proteus mirabilis (n=1)] was recovered. The sensitivity after 24 h incubation was 88 % for chromID ESBL and 85 % for BLSE agar. At 48 h, the sensitivity of chromID ESBL increased to 94 % and was higher than that obtained with BLSE agar. The positive predictive value at 24 h for chromID ESBL was 38.7 % [95 % confidence interval (95 % CI) 28.3 -50.2 %)], which was significantly higher than that for BLSE agar [15.4 %, 95 % CI 10.1 -21.5 %]. On both media, false-positive results were mostly due to Pseudomonas aeruginosa and to Enterobacteriaceae overproducing chromosomal cephalosporinase (Enterobacter spp.) or a chromosomal penicillinase (Klebsiella oxytoca). This study showed that chromID ESBL, a ready-to-use chromogenic selective medium, is sensitive and specific for rapid, presumptive identification of ESBL-producing Enterobacteriaceae. Its chromogenic properties and its selectivity are particularly useful in specimens containing resident associated flora.
The New Steroid Analog RU 486 Inhibits Glucocorticoid Action in Man (1984)

RU 486 [17 beta-hydroxy-11 beta-(4- dimethylaminophenyl )-17 alpha-(prop-1- ynyl )-estra-4,9-dien-3-one] is a new steroid analog which antagonizes glucocorticoid action at the receptor level in animals. To assess its potential antiglucocorticoid activity in man we studied the pituitary-adrenal response to RU 486 in normal men. The compound was administered at 0200 h and plasma cortisol and lipotropins (LPH) were measured hourly for 10 h. After 400 mg RU 486 significant and sustained elevation of both hormones occurred during the 0700-1200 h period: mean (+/- SE) plasma levels after placebo or RU 486 during this interval were, respectively, for cortisol (ng/ml), 63.4 +/- 8.2 and 112.7 +/- 2.9 (P less than 0.02); and for LPH (pg/ml), 34.8 +/- 11.3 and 71.6 +/- 15.4 (P less than 0.01). The 200- and 100-mg doses induced only transient cortisol and LPH increases. Administration of RU 486 (400 mg) at 1400 h induced no increase in plasma cortisol compared to placebo in the corresponding 2000 to 2400 h period. When RU 486 was administered concomitantly with dexamethasone (1 mg) at 2400 h, dose-dependent blockade of the dexamethasone-induced cortisol suppression at 0900 h was found (r = 0.62, P less than 0.01); this blockade was partial after the 100-mg dose, but complete after the 400-mg dose. Plasma LPH and ACTH showed parallel variations. We conclude that RU 486 antagonizes the negative pituitary feedback of both the nocturnal endogenous cortisol rise and exogenously administered dexamethasone. These actions are consistent with an antiglucocorticoid activity of this compound in man.
groupTime (2006)

As our business, academic, and personal lives continue to move at an ever-faster pace, finding times for busy people to meet has become an art. One of the most perplexing challenges facing groupware is effective asynchronous group scheduling (GS). This paper presents a lightweight interaction model for GS that can extend its reach beyond users of current group calendaring solutions. By expressing availability in terms of preferences, we create a flexible framework for GS that preserves plausible deniability while exerting social pressure to encourage honesty among users. We also propose an ontology that enables us to model user preferences with machine learning, predicting user responses to further lower cognitive load. The combination of visualization/direct manipulation with machine learning allows users to easily and efficiently optimize meeting times. We also suggest resulting design implications for this class of intelligent user interfaces.
Personality Prediction Through CV Analysis using Machine Learning Algorithms for Automated E-Recruitment Process (2021)

Personality of a person plays a crucial role in the organizational progress and also in the self-development process in an individual's life. One of the typical ways to predict the person's personality is either by a standard review or by scrutinizing the Curriculum Vitae of the candidate. The Conventional method of recruiting the candidates involves manual short listing of job seekers resumes according to the requirement of the company. In this work, a system that automates the task of segregating candidates based on eligibility criteria and personality evaluation in a recruitment process is proposed. To meet this requirement an online application is developed for the registration of candidate's details and analysis of candidate's personalities through an online Multiple-Choice Question (MCQ) test containing personality quizzes. Then the system analyzes professional eligibility by comparing the uploaded Curriculum Vitae trained datasets. This system employs a machine learning algorithm namely “Logistic Regression” which helps to choose fair decisions to recruit a suitable candidate. Thus, the final results of the personality quizzes will be sent to both candidates and the admin.
