A Method for Scalable First-Order Rule Learning on Twitter Data (2019)

We propose a method for scalable first-order rule learning on large-scale Twitter data. By learning rules, probabilistic inference queries can be executed to reason over the data to ascertain its veracity. Our method employs a divide-and-conquer approach, graph-based modeling, and data parallel processing during rule learning using a commodity cluster to overcome the problem of slow structure learning on large-scale Twitter data. The first-order predicates (constructed on the posts) are first partitioned in a balanced way by pivoting around users to reduce the chance of missing relevant rules. By constructing a weighted graph and applying graph partitioning, balanced partitions of the ground predicates can be created. Each partition is then processed using an existing structure learning approach to get the set of rules for that partition. We report a preliminary evaluation of our method to show that it offers a promising solution for scalable first-order rule learning on Twitter data.

Treatment of Human Lens Epithelium with High Levels of Nanoceria Leads to Reactive Oxygen Species Mediated Apoptosis (2020)

Nanoceria (cerium oxide nanoparticles) have been shown to protect human lens epithelial cells (HLECs) from oxidative stress when used at low concentrations. However, there is a lack of understanding about the mechanism of the cytotoxic and genotoxic effects of nanoceria when used at higher concentrations. Here, we investigated the impact of 24-hour exposure to nanoceria in HLECs. Nanoceria's effects on basal reactive oxygen species (ROS), mitochondrial morphology, membrane potential, ATP, genotoxicity, caspase activation and apoptotic hallmarks were investigated. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) studies on isolated mitochondria revealed significant uptake and localization of nanoceria in the mitochondria. At high nanoceria concentrations (400 µg mL<sup>-1</sup>), intracellular levels of ROS were increased and the HLECs exhibited classical hallmarks of apoptosis. These findings concur with the cells maintaining normal ATP levels necessary to execute the apoptotic process. These results highlight the need for nanoceria dose-effect studies on a range of cells and tissues to identify therapeutic concentrations in vitro or in vivo.
Amifostine for children with medulloblastoma treated with cisplatin‐based chemotherapy (2004)

In adult patients, amifostine appears to ameliorate cisplatin-related nephrotoxicity and ototoxicity. We assessed the safety and efficacy of amifostine in 11 children with newly diagnosed medulloblastoma/primitive neuroectodermal tumor treated with radiotherapy and vincristine, lomustine, and cisplatin. Amifostine was administered immediately prior to and 4 hr into the cisplatin infusion. Amifostine caused assymptomatic hypotension and hypocalcemia in 18 and 82% of patients, respectively. Despite amifostine use, 78% of patients developed significant ototoxicity. Although relatively well tolerated, amifostine does not appear to have a major impact on ameliorating the risk of developing significant nephro- and ototoxicity in children with medulloblastoma. Larger studies will help clarify these findings.

203 Effect of self-lubrication function on the destruction of the carbon particle (2000)

Recent years, demand of the slide equipment that called manual equipment and welfare equipment increases very much. So, It is urgent to clarify the elucidation of tribology characteristics in human life speed area. In this study, the elucidation of tribology mechanism which particle size of solid lubricant and destruction of the solid lubricant for smooth division caused was tried. And quantitative evaluation of torque value and particle size was tried using Human symbiotic type lubrication evaluation system which hybridized the small environmental test lab and journal axial and smooth set tester.
Computerized detection of masses in digital mammograms: Automated alignment of breast images and its effect on bilateral‐subtraction technique (1994)

An automated technique for the alignment of right and left breast images has been developed for use in the computerized analysis of bilateral breast images. In this technique, the breast region is first identified in each digital mammogram by use of histogram analysis and morphological filtering operations. The anterior portions of the tracked breast border and computer-identified nipple positions are selected as landmarks for use in image registration. The paired right and left breast images, either from mediolateral oblique or craniocaudal views, are then registered relative to each other by use of a least-squares matching method. This automated alignment technique has been applied to our computerized detection scheme that employs a nonlinear bilateral-subtraction method for the initial identification of possible masses. The effectiveness of using bilateral subtraction in identifying asymmetries between corresponding right and left breast images is examined by comparing detection performances obtained with various computer-simulated misalignments of 40 pairs of clinical mammograms. Based on free-response receiver operating characteristic and regression analyses, the detection performance obtained with the automated alignment technique was found to be higher than that obtained with simulated misalignments. Detection performance decreased gradually as the amount of simulated misalignment increased. These results indicate that automatic alignment of breast images is possible and that mass-detection performance appears to improve with the inclusion of asymmetric anatomic information but is not sensitive to slight misalignment.
Impact of Biodiesel on Lubricant Corrosion Performance (2009)

&lt;div class="htmlview paragraph"&gt;The global use of biodiesel fuel blends derived from fatty acid methyl esters (FAME) is increasing; driven by legislation derived from political, economic and environmental factors. The presence of FAME biodiesel changes the operating environment of the engine and after treatment devices, affecting the performance characteristics and requirements of the lubricant. As part of a wider research project into the impact of biologically-sourced fuels on crankcase lubricant performance, this paper documents the impact of biodiesel on corrosion-related performance. The effect of FAME biodiesel on lubricant corrosion control and the differences in performance due to FAME source are described. Mechanistic studies into the corrosive nature of FAME are reported. Novel lubricant technologies tailored to control the negative impact of FAME in the crankcase are demonstrated.&lt;/div&gt;
The Enigmatic Origin of Papillomavirus Protein Domains (2017)

Almost a century has passed since the discovery of papillomaviruses. A few decades of research have given a wealth of information on the molecular biology of papillomaviruses. Several excellent studies have been performed looking at the long- and short-term evolution of these viruses. However, when and how papillomaviruses originate is still a mystery. In this study, we systematically searched the (sequenced) biosphere to find distant homologs of papillomaviral protein domains. Our data show that, even including structural information, which allows us to find deeper evolutionary relationships compared to sequence-only based methods, only half of the protein domains in papillomaviruses have relatives in the rest of the biosphere. We show that the major capsid protein L1 and the replication protein E1 have relatives in several viral families, sharing three protein domains with <i>Polyomaviridae</i> and <i>Parvoviridae</i>. However, only the E1 replication protein has connections with cellular organisms. Most likely, the papillomavirus ancestor is of marine origin, a biotope that is not very well sequenced at the present time. Nevertheless, there is no evidence as to how papillomaviruses originated and how they became vertebrate and epithelium specific.
An Optical Fiber Tip Micrograting Thermometer (2011)

An ~ 12-μm-long Bragg grating was engraved in an ~ 5-μm-diameter optical fiber tip by focused ion beam (FIB) milling. An ~ 10-dB extinction was achieved at 1570 nm with only 11 indentations. The grating was used for temperature sensing, and it exhibited a temperature sensitivity of ~ 22 pm°C.
Packing Configurations of PBX‐9501 Cylinders to Reduce the Probability of a Deflagration to Detonation Transition (DDT) (2016)

Abstract The detonation of hundreds of explosive devices from either a transportation or storage accident is an extremely dangerous event. This paper focuses on identifying ways of packing/storing arrays of explosive cylinders that will reduce the probability of a Deflagration to Detonation Transition (DDT). The Uintah Computational Framework was utilized to predict the conditions necessary for a large scale DDT to occur. The results showed that the arrangement of the explosive cylinders and the number of devices packed in a “box” greatly effects the probability of a detonation.
Atomic Layer Deposition of Molybdenum and Tungsten Oxide Thin Films Using Heteroleptic Imido-Amidinato Precursors: Process Development, Film Characterization, and Gas Sensing Properties (2018)

Heteroleptic bis(tert-butylimido)bis(N,N′-diisopropylacetamidinato) compounds of molybdenum and tungsten are introduced as precursors for atomic layer deposition of tungsten and molybdenum oxide thin films using ozone as the oxygen source. Both precursors have similar thermal properties but exhibit different growth behaviors. With the molybdenum precursor, high growth rates up to 2 Å/cycle at 300 °C and extremely uniform films are obtained, although the surface reactions are not completely saturative. The corresponding tungsten precursor enables saturative film growth with a lower growth rate of 0.45 Å/cycle at 300 °C. Highly pure films of both metal oxides are deposited, and their phase as well as stoichiometry can be tuned by changing the deposition conditions. The WOx films crystallize as γ-WO3 at 300 °C and above, whereas the films deposited at lower temperatures are amorphous. Molybdenum oxide can be deposited as either amorphous (≤250 °C), crystalline suboxide (275 °C), a mixture of suboxide and α-MoO3 (300 °C), or pure α-MoO3 (≥325 °C) films. MoOx films are further characterized by synchrotron photoemission spectroscopy and temperature-dependent resistivity measurements. A suboxide MoOx film deposited at 275 °C is demonstrated to serve as an efficient hydrogen gas sensor at a low operating temperature of 120 °C.
Expressive synthesis: how crucial is voice quality? (2004)

This paper compares the emotive colouring that can be achieved in synthesis by f/sub 0/ manipulations alone (f/sub 0/ only) as compared to manipulations of f/sub 0/ with voice quality (VQ+f/sub 0/), and asks how crucial large f/sub 0/ excursions are in signalling strong emotions. Are they overwhelmingly important, with voice quality contributing mainly to finer distinctions for milder affects? Or are voice quality and large f/sub 0/ differences required for the strong emotions? The 'VQ+f/sub 0/' stimuli, of an utterance synthesised using the LF voice source in KLSYN88 with breathy, whispery, lax-creaky, modal, tense and harsh voice qualities (Gobl et al. (2002)), were further manipulated to replicate the f/sub 0/ differences described in Mozziconacci et al. (1995) for 6 emotions, matched to the most appropriate voice quality. The 'f/sub 0/ only' stimuli used the same set of f/sub 0/ contours, but retained source settings for modal voice. 10 listeners rated the affective colouring of the stimuli on a seven-point scale, in terms of pairs of opposite attributes. For both strong and milder affects the 'VQ+f/sub 0/' stimuli achieved much higher ratings than the 'f/sub 0/ only' stimuli, which were relatively ineffective. Implications for the synthesis of expressive speech are discussed.
Effects of Ion Channel Blockers and Phorbol Ester Treatments on [3H]Dopamine Release and Neurotensin Facilitation of [3H]Dopamine Release from Rat Mesencephalic Cells in Primary Culture (1994)

In this work, we tested the effect of ion channel blockers and of phorbol ester treatments on [ 3 H]dopamine ([ 3 H]DA) release and neurotensin (NT)‐induced facilitation of [ 3 H]DA release from cultures of rat fetal mesencephalic cells. The potassium channel blockers tetraethylammonium and 4‐aminopyridine increased basal [ 3 H]DA release and decreased K + ‐evoked [ 3 H]DA release, whereas apamin was without effect. K + ‐evoked [ 3 H]DA release was decreased by ω‐conotoxin and nifedipine, totally suppressed by cadmium, and unaffected by amiloride. These results show the differential sensitivity of [ 3 H]DA release to blockade of various ion channels and suggest the involvement of N‐type, L‐type, and non‐L‐non‐N‐type, but not T‐type, voltage‐sensitive calcium channels in K + ‐evoked release. Phorbol 12‐myristate 13‐acetate increased both spontaneous and K + ‐evoked [ 3 H]DA release, suggesting a modulatory action of protein kinase C on DA release in this system. Unexpectedly, however, the effects of the phorbol ester were not counteracted by the protein kinase C inhibitors H7, staurosporine, or polymyxin B. NT‐induced facilitation of K + ‐evoked [ 3 H]DA release was insensitive to most of the ion channel blockers, except cadmium (64% decrease in NT effect), suggesting that the corresponding potassium' and calcium channels were not involved in the effect of NT on [ 3 H]DA release in this system. The NT effect was totally suppressed by phorbol ester treatments, indicating a possible desensitization of the corresponding transduction mechanisms after protein kinase C activation.

Down-regulation of Langerhans cell protein kinase C-β isoenzyme expression in inflammatory and hyperplastic dermatoses (1995)

The family of protein kinase C (PKC) isoenzymes plays a fundamental part in signal transduction, and thereby regulates important cellular functions, including growth, differentiation, cytokine production and adhesion molecule expression. In lesional psoriatic skin, Ca(2+)-dependent PKC activity, PKC-beta protein and epidermal Langerhans cell (LC) PKC-beta immunostaining are significantly decreased, indicating activation and subsequent down-regulation of PKC. Whether these changes occur in other inflammatory/hyperplastic dermatoses is, however, unknown. We examined PKC-alpha and PKC-beta expression in normal skin, psoriasis, cutaneous T-cell lymphoma (CTCL), lamellar ichthyosis, non-bullous ichthyosiform erythroderma, atopic dermatitis, urushiol-induced allergic contact dermatitis, and sodium lauryl sulphate (SLS)-induced irritant contact dermatitis. Cryostat sections were stained for PKC-alpha and PKC-beta, and the LC marker CD1a, using an immunoperoxidase technique and specific monoclonal antibodies. Double-labelling studies, in normal skin, revealed co-expression of PKC-beta and CD1a by epidermal LCs. Analysis of the number of PKC-beta+ and CD1a+ epidermal LCs, in diseased compared with normal skin, revealed three categories: (i) in psoriasis and CTCL, the PKC-beta+ epidermal LC number was significantly reduced, whereas the CD1a+ epidermal LC number was unchanged; (ii) in allergic and irritant contact dermatitis, both PKC-beta+ and CD1a+ epidermal LCs were significantly reduced in number; and (iii) in atopic dermatitis, the PKC-beta+ epidermal LC number was normal, and CD1a+ epidermal LCs were significantly increased in number. Moreover, the ratio of epidermal LC PKC+/CD1a+ was reduced in all the dermatoses studied, suggesting activation of PKC-beta, with subsequent down-regulation. Within the dermis, increased PKC-beta staining of infiltrating cells was observed in all the conditions studied except lamellar ichthyosis and non-bullous ichthyosiform erythroderma. These data indicate that: (i) down-regulation of LC PKC-beta occurs in a variety of inflammatory and hyperplastic skin disorders, and is not unique to psoriasis, and (ii) the pattern of epidermal LC PKC-beta and CD1a expression varies among the diseases studied. In mice, PKC activation induces LC migration. Thus, down-regulation of epidermal LC PKC-beta associated with reduced CD1a+ epidermal LCs in allergic and irritant contact dermatitis suggests that PKC-beta may transduce the signal for migration of LCs from human epidermis.

Multi-Agent pattern recognition mechanism for detecting distributed denial of service attacks (2010)

Distributed denial of service (DDoS) attacks pose a significant threat to the smooth operations of today&apos;s online critical services and applications. Existing mechanisms to detect these attacks have had limited success. With the rapid growth in size and bandwidth of contemporary computer networks, an efficient and effective distributed solution is needed for detecting DDoS attacks. In this study, the authors propose a multiagent pattern recognition mechanism for detecting DDoS attacks, in adistributed fashion. Our proposed solution is very effective in detecting such attacks launched against victim servers residing inside a production network which has multiple gateways to the Internet. Using simulation, the authors show that our proposed mechanism achieves a high degree of accuracy in detecting DDoS attacks, with low false alarm rates, using a reasonable numbers of attack detection agents collaboratively operating in a typical production network. The authors also study the relationship of the number of agents participating in the attack detection process and the false alarm rate of the detection scheme.
<title>Water refractive index in dependence on temperature and wavelength: a simple approximation</title> (2003)

Water is the most important biological liquid. On the basis of literature data we present a simple approximation of water refractive index in dependence on temperature and wavelength in the spectral range from 200 to 1000 nm. The approximation is important for different applications in biomedical optics and optics of tissues.
[Selective reduction of NOx with propene over SnO2/Al2O3 catalyst]. (2004)

In the study, a series of SnO2/Al2O3 catalysts with various Sn loading were prepared by three different methods (impregnation, co-precipitation and single step sol-gel) and their catalytic activities for the selective reduction of NOx with propene were investigated. It was found that the catalyst preparation method as well as the Sn loading exerted a significant influence on the catalyst activity. Catalysts prepared by sol-gel method exhibited the highest activity toward NOx reduction and the optimal Sn loading is 5%. 5% SnO2/Al2O3 catalyst prepared by sol-gel method was found to be less inhibited by the presence of H20 than those prepared by other methods. Even in the co-presence of H2O and SO2, it still showed the highest activity. The increase of oxygen and propene concentration promotes the NOx reduction, respectively.
A Transparent Approach of Enabling SaaS Multi-tenancy in the Cloud (2010)

It has become more and more obvious that in Cloud Computing, applications are key drivers to make Cloud business a success. Multi-tenancy is a critical technology to allow one instance of application serving multiple customers at the same time to share Cloud resources and achieve high operational efficiency. There are different options of realizing multi-tenancy, in this paper we describe a transparent approach of making existing Web applications to support multi-tenancy and run in the public Cloud. Our approach includes intercepting the Web requests and deriving the tenant context, carrying the tenant context with a thread in the Web container, manipulating the isolation points (application artifacts that need to be isolated) in a Web application, and propagating tenant context to remote Cloud resources (such as database server, and message queue server) when necessary. With this approach, volumes of existing Web applications could quickly be provisioned through a public Cloud platform without rewriting the original source code. We have also implement a real system based on the common multi-tenancy model that separate the concerns of application developer, SaaS operator, tenant administrator, and tenant user. We finally integrate the SaaS multi-tenancy technique with Cloud platform services.
Inhibition of soluble epoxide hydrolase improves the impaired pressure–natriuresis relationship and attenuates the development of hypertension and hypertension-associated end-organ damage in Cyp1a1-Ren-2 transgenic rats (2011)

Our present findings indicate that chronic treatment with the sEH inhibitor c-AUCB substantially attenuates the development of malignant hypertension in I3C-induced rats likely via improvement of the renal autoregulatory efficiency and the pressure-natriuresis relationship.
Survival, local control, and health‐related quality of life in patients with oligometastatic and polymetastatic spinal tumors: A multicenter, international study (2018)
