Tagging the Past: Experiments using the Saga Corpus

There is an increasing interest in the NLP community in developing tools for annotating historical data, for example, to facilitate research in the field of corpus linguistics. In this work, we experiment with several PoS taggers using a sub-corpus of the Icelandic Saga Corpus. This is carried out in three main steps. First, we evaluate taggers, which were trained on Modern Icelandic, when tagging Old Icelandic. Second, we semi-automatically correct errors in the training corpus using a bootstrapping method. Finally, we evaluate the taggers on the corrected training corpus. The best performing single tagger is Stagger, a tagger based on the averaged perceptron algorithm, obtaining an accuracy of 91.76%. By combining the output of three taggers, using a simple voting scheme, the accuracy increases to 92.32%.
A new share frequent itemsets mining using incremental BitTable knowledge

The share measure has been proposed as an important measure for mining association rules. The value of share itemsets provides useful information such as total profits and total customer purchased quantities associated with itemsets in database. The share-frequent itemsets mining problems become a very important research issue in data mining. Existing share-frequent itemsets mining algorithms are based on static database so knowledge must be rebuilded when the minimum share threshold is changed or database is modified either appended or updated. This paper proposes a novel BitTable knowledge for incremental and interactive share-frequent itemsets mining in multiple minimum share thresholds without rebuilding BitTable knowledge. It is effective for incremental and interactive mining to take advantage of the previous BitTable knowledge and the previous mining results.
Progression Model Tissue Microarray (TMA) for the Study of Uterine Carcinomas

Cervical and endometrial uterine carcinomas are heterogeneous groups of cancers, which are preceded by preneoplastic lesions. More accurate tools are needed to improve the diagnosis and to define markers which may be relevant for the diagnosis, prediction of disease progression and therapeutic response. High throughput technologies for testing and validating molecular targets in cancer lesions and in their precursors are presently available. Among them, the tissue microarray (TMA) presents the advantage of a morphological control of the analyzed tissue fragment. In this article, we review the different aspects of the TMA technology with a special consideration to a uterine carcinogenesis model.
Underwater Moving Object Detection Based on Codebook Model

Underwater video intelligent monitoring system extracts moving objects in a complex and dynamic scene with the impact of wave, illumination changes and reflection, while needs real-time character. To solve these situations, underwater moving object detection algorithm based on codebook model was presented. The algorithm creates a background codebook for each pixel according to color distortion and brightness distortion, and then extracts the moving objects using the current pixel to match with code words in the codebook. To adapt the complex changes of scene, the algorithm updates adaptively the background codebook model using the sample value of pixel of current image. The experiments show that the algorithm can extract the complete moving objects by overcoming the impact of underwater environment and inhibiting noise. And the algorithm has perfect real-time character.
A coaching framework for developing the psychological capital of a global mindset

The impact of critical experience on international executives can have serious consequences, assignments may fail. So coaching support may enhance their psychological capital and global competencies. This small heuristic study involved five co-researchers specialised in coaching international executives across the world on career and leadership development. The themes and qualities of their coaching approaches were synthesised into a composite coaching framework, triangulated with literature and; highlighted person-environment matching based on experience of nomadic work/life style and the use of home-world coaching dialogue to appreciate ‘home as a process’.
Effects of Housing Systems on Behaviour, Performance and Welfare of Fast-growing Broilers

This experiment aimed to evaluate the effects of different housing systems on behavioral activities, welfare and meat quality of fast-growing broilers. Two hundred broilers were allocated into two housing systems: indoor housing vs indoor with outdoor access. Their general behavior (feeding, drinking, fighting, standing, lying, walking, investigating, dust-bathing and preening) was observed, and tonic immobility, fluctuating asymmetry of legs and wings were measured, and meat quality was analyzed. The results showed that the indoor-housed broilers with outdoor access had significant higher standing, walking, investigating, dust-bathing and preening than those indoor only. However, farming system was not found to significantly affect their feeding, drinking and fighting activities (p>0.05). The value of FA of tibia length of the broilers with outdoor access was significantly lower than that of the indoor-housed birds (1.57±1.30 vs 2.76±1.40, p<0.05), while no difference was found for the value of FA in tibia diameter and wing length (p>0.05). TI of the broilers with outdoor access was 165.5 that was significantly higher than that (147.2) of the indoor birds (p<0.05). However, death rate in the outdoor run groups was significantly higher than that of the indoor ones (2.0±0.81 vs 4.0±0.82, p<0.05). Meat quality was not affected by the two farming systems. It can be concluded that the results of this study may suggest that the indoor housing with outdoor access provides enriched environment for broilers and facilitates the expression of natural behaviors of the broilers but resulted in poorer performance and higher death rate.
Targeting hexokinase 2 enhances response to radio-chemotherapy in glioblastoma

First-line cancer therapies such as alkylating agents and radiation have limited survival benefits for Glioblastoma (GBM) patients. Current research strongly supports the notion that inhibition of aberrant tumor metabolism holds promise as a therapeutic strategy when used in combination with radiation and chemotherapy. Hexokinase 2 (HK2) has been shown to be a key driver of altered metabolism in GBM, and presents an attractive therapeutic target. To date, no study has fully assessed the therapeutic value of targeting HK2 as a mechanism to sensitize cells to standard therapy, namely in the form of radiation and temozolomide (TMZ). Using cell lines and primary cultures of GBM, we showed that inducible knockdown of HK2 altered tumor metabolism, which could not be recapitulated by HK1 or HK3 loss. HK2 loss diminished both in vivo tumor vasculature as well as growth within orthotopic intracranial xenograft models of GBMs, and the survival benefit was additive with radiation and TMZ. Radio-sensitization following inhibition of HK2 was mediated by increased DNA damage, and could be rescued through constitutive activation of ERK signaling. This study supports HK2 as a potentially effective therapeutic target in GBM.
Nanoparticles for Brain Drug Delivery

The central nervous system, one of the most delicate microenvironments of the body, is protected by the blood-brain barrier (BBB) regulating its homeostasis. BBB is a highly complex structure that tightly regulates the movement of ions of a limited number of small molecules and of an even more restricted number of macromolecules from the blood to the brain, protecting it from injuries and diseases. However, the BBB also significantly precludes the delivery of drugs to the brain, thus, preventing the therapy of a number of neurological disorders. As a consequence, several strategies are currently being sought after to enhance the delivery of drugs across the BBB. Within this review, the recently born strategy of brain drug delivery based on the use of nanoparticles, multifunctional drug delivery systems with size in the order of one-billionth of meters, is described. The review also includes a brief description of the structural and physiological features of the barrier and of the most utilized nanoparticles for medical use. Finally, the potential neurotoxicity of nanoparticles is discussed, and future technological approaches are described. The strong efforts to allow the translation from preclinical to concrete clinical applications are worth the economic investments.
A Comparative Analysis of the SF-12 and the SF-36 among Ischaemic Heart Disease Patients

This paper investigated whether the SF-12 could replace the SF-36 in the measurement of health status among ischaemic heart disease patients. The SF-36 and SF-12 were administered to 105 cardiac patients. The SF-36 summary scores were strongly correlated and similar to the SF-12 summary scores. Also, the SF-12 scores were as powerful as the SF-36 summary scores in discriminating between subgroups of patients categorized according to their self-reported health status or angina classification. It is suggested that when there is a need to collect routine information about cardiac patients' general physical and mental health, the SF-12 is preferable to the SF-36 because of its brevity and acceptability to patients.
Advanced logical superposition modulation based video streaming multicast system over wireless networks

In this paper, we present an advanced logical superposition modulation based video streaming multicast system over a wireless networks. The traditional logical superposition modulation scheme generates symbols using a prefixed modulation scheme to overcome wireless channel diversity. In contrast, our proposed logical superposition modulation determines logical superposition modulation scheme according to time-varying wireless channel conditions in order to maximize overall network throughput, similar to state-of-art adaptive modulation schemes. in addition, two-layer SVC video streams are effectively mapped to the determined superposition modulation scheme to support better quality video streaming. Experimental results show the performance of our proposed system.
Story Book: An Efficient Extensible Provenance Framework

Most application provenance systems are hard coded for a particular type of system or data, while current provenance file systems maintain in-memory provenance graphs and reside in kernel space, leading to complex and constrained implementations. Story Book resides in user space, and treats provenance events as a generic event log, leading to a simple, flexible and easily optimized system. We demonstrate the flexibility of our design by adding provenance to a number of different systems, including a file system, database and a number of file types, and by implementing two separate storage backends. Although Story Book is nearly 2.5 times slower than ext3 under worst case workloads, this is mostly due to FUSE message passing overhead. Our experiments show that coupling our simple design with existing storage optimizations provides higher throughput than existing systems.
“I have always been so afraid”: Fearsome Encounters in Unni Lindell’s Rødhette

Abstract Norwegian crime writer Unni Lindell’s novel Rødhette [Red Riding Hood] (Oslo: Aschehoug & Co, 2004/2010) is a narrative about a woman whose feeling of safety transforms into a fear of violation, and how her defence against this fear takes the form of systematic violence. The novel is a rewriting of the traditional tale of “Little Red Riding Hood” and is a comment on the patriarchal premises of the most widely known version of this folktale. In the article, I discuss the representation of the female murderer as being in the grip of an affective economy based on the fear of male violence, represented in the novel by the metaphor of the “wolf”, and how fear grows into a comprehensive, moral and pragmatic, murderous orientation towards the world after an experience of violence. Theoretically, I draw on affect theory and particularly Sara Ahmed’s ideas about the affective politics of fear (The cultural politics of emotion. Edinburgh: Edinburgh University Press, 2014) and how this fear turns into a significant qualifier in encounters with people who are experienced as strangers (Strange encounters: Embodied others in post-coloniality. London: Routledge, 2000). Fear is treated in Lindell’s novel as a psychological constriction and a tool for the construction of agency, through which the mechanisms of othering and violence are explored.
Journal of Experimental Psychology: Human Learning and Memory a Processing Approach to the Dual Coding Hypothesis

This paper explores the notion that imagery encoding differs from other forms of encoding with regard to the particular processes invoked. Words encoded as images were recalled after words that were rehearsed, and words clustered in output according to processing mode. Clustering by modality occurred even when grouping according to semantic categories conflicted with grouping by processing mode. In addition, more words were recalled if both verbal and visual encoding was utilized, compared with when only one mode was used. Two selective interference tasks revealed that silent verbal rehearsal seems to involve some of the same processing mechanisms activated during encoding of phonemic information. However, these tasks revealed no effects of visual perception selectively interfering with visual imagery encodings. People often have been credited with the ability to encode information either verbally and/or in terms of mental images (see Pai-vio, 1971). Recently, this notion has been attacked by theorists who postulate a single, abstract mode of internal representation (e.g., Pylyshyn, 1973). Rather than attempting to determine the ultimate form of representation in long-term memory, it may be more profitable to see whether there are functional differences between different modes of representing information. Instead We wish to thank E. Smith, A. Glass, and H. Egeth ifor helpful remarks. We especially wish to thank Gordon Bower who extended both perceptive comments and financial support (NIMH Grant No. of focusing on the end products of encoding, we will consider whether the encoding process itself differs in important ways when people encode visual images of the refer-ents of words as opposed to simply encoding the words themselves (i.e., rehearsing verbally). The present approach to the dual coding hypothesis centers on the idea that encoding visual images as opposed to verbal representations requires different processing channels. We explore the implications of this idea with regard to the nature of en-codings shortly after they are formed. The present study can be divided into two parts. In the first two experiments we investigate whether imagery and verbal encoding use different processing mechanisms. The final two experiments then attempt to discover whether the processes underlying the use of imagery to retain words are also involved in like-modality perception. If imagery and verbal encoding require different processing channels, we might expect material being encoded to become organized in terms of modality. For example,
Emotional Content in Wikipedia Articles on Negative Man-Made and Nature-Made Events

Wikipedia emphasizes the objectivity of content. Yet, Wikipedia articles also deal with negative events that potentially elicit intense emotions. Undesirable outcomes (e.g., earthquakes) are known to elicit sadness, while undesirable outcomes caused by others’ actions (e.g., terrorist attacks) are known to elicit anger. Internet users’ emotional responses are likely to end up in Wikipedia articles on those events as characteristics of Internet users spill over to Wikipedia articles. Therefore, we expected that Wikipedia articles on terrorist attacks contain more anger-related and less sadness-related content than articles on earthquakes. We analyzed newly created Wikipedia articles about the two events (Study 1) as well as more current versions of those Wikipedia articles after the events had already happened (Study 2). The results supported our expectations. Surprisingly, Wikipedia articles on those two events contained more emotional content than related Wikipedia talk pages (Study 3). We discuss the implications for Wikipedia and future research.
SiGe BiCMOS 65-GHz BPSK transmitter and 30 to 122 GHz LC-varactor VCOs with up to 21% tuning range

This work presents a systematic study of millimetre-wave, low-noise, widely-tuneable differential Colpitts VCOs. A design methodology was developed and validated experimentally over thirteen different varactor-tuned (VCO) and fixed-frequency L-C oscillators spanning the 30-GHz to 122-GHz frequency range. All circuits employ accumulation-mode n-MOS varactors, and multi-turn on-chip inductors. The 35-GHz and 60-GHz oscillators achieve phase noise of -112.7 dBc and -104 dBc/Hz, respectively at 1-MHz offset and deliver +4 dBm differential output power while a push-push implementation demonstrates 15-GHz (21%) tuning range from 63.5 GHz to 78.5 GHz. A directly-modulated, 65-GHz binary phase shift keying (BPSK) transmitter is also implemented.
Smooth-bitrate adaptation method for HTTP streaming in vehicular environments

Recent years have seen a fast growth of video on-demand (VOD) services over HTTP. In order to improve service quality, video services are required to support different network conditions. For vehicular environments, this study proposes a novel adaptation method that improves quality of experience (QoE) by 1) reducing the number of bitrate switches and 2) avoiding sudden quality changes. The experiment shows that proposed method can provide a smooth video even under highly fluctuating network conditions.
Astaxanthin Inhibits JAK/STAT-3 Signaling to Abrogate Cell Proliferation, Invasion and Angiogenesis in a Hamster Model of Oral Cancer

Identifying agents that inhibit STAT-3, a cytosolic transcription factor involved in the activation of various genes implicated in tumour progression is a promising strategy for cancer chemoprevention. In the present study, we investigated the effect of dietary astaxanthin on JAK-2/STAT-3 signaling in the 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis model by examining the mRNA and protein expression of JAK/STAT-3 and its target genes. Quantitative RT-PCR, immunoblotting and immunohistochemical analyses revealed that astaxanthin supplementation inhibits key events in JAK/STAT signaling especially STAT-3 phosphorylation and subsequent nuclear translocation of STAT-3. Furthermore, astaxanthin downregulated the expression of STAT-3 target genes involved in cell proliferation, invasion and angiogenesis, and reduced microvascular density, thereby preventing tumour progression. Molecular docking analysis confirmed inhibitory effects of astaxanthin on STAT signaling and angiogenesis. Cell culture experiments with the endothelial cell line ECV304 substantiated the role of astaxanthin in suppressing angiogenesis. Taken together, our data provide substantial evidence that dietary astaxanthin prevents the development and progression of HBP carcinomas through the inhibition of JAK-2/STAT-3 signaling and its downstream events. Thus, astaxanthin that functions as a potent inhibitor of tumour development and progression by targeting JAK/STAT signaling may be an ideal candidate for cancer chemoprevention.
Polymerization of tubulin in vivo: direct evidence for assembly onto microtubule ends and from centrosomes

Microtubule assembly in vivo was studied by hapten-mediated immunocytochemistry. Tubulin was derivatized with dichlorotriazinylaminofluorescein (DTAF) and microinjected into living, interphase mammalian cells. Sites of incorporation were determined at the level of individual microtubules by double-label immunofluorescence. The haptenized tubulin was localized by an anti- fluorescein antibody and a second antibody conjugated with fluorescein. Total microtubules were identified by anti-tubulin and a secondary antibody conjugated with rhodamine. Contrary to recent studies (Salmon, E. D., et al., 1984, J. Cell Biol., 99:2165-2174; Saxton, W. M., et al., 1984, J. Cell Biol., 99:2175-2186) which suggest that tubulin incorporates all along the length of microtubules in vivo, we found that microtubule assembly in interphase cells was in vivo, as in vitro, an end-mediated process. Microtubules that radiated out toward the cell periphery incorporated the DTAF-tubulin solely at their distal, that is, their plus ends. We also found that a proportion of the microtubules connected to the centrosomes incorporated the DTAF-tubulin along their entire length, which suggests that the centrosome can nucleate the formation of new microtubules.
A self-adaptive similarity-based fitness approximation for evolutionary optimization

Evolutionary algorithms used to solve complex optimization problems usually need to perform a large number of fitness function evaluations, which often requires huge computational overhead. This paper proposes a self-adaptive similarity-based surrogate model as a fitness inheritance strategy to reduce computationally expensive fitness evaluations. Gaussian similarity measurement, which considers the ruggedness of the landscape, is proposed to adaptively regulate the similarity in order to improve the accuracy of the inheritance fitness values. Empirical results on three traditional benchmark problems with 5, 10, 20, and 30 decision variables and on the CEC'13 test functions with 30 decision variables demonstrate the high efficiency and effectiveness of the proposed algorithm in that it can obtain better or competitive solutions compared to the state-of-the-art algorithms under a limited computational budget.
On an Evaluation of Network Intrusion Dispersion

The widespread of Internet worms is an issue of concern. A worm program tries to compromise systems in a large scale network. To handle the disaster proactively, it is very essential to evaluate the worm dispersion. We propose an evaluation model for the network intrusion dispersion on a spread of worms. The model scrutinizes important factors from a network infrastructure then calculates the dispersion value by using a rule-based fuzzy technique. These significant factors are generated from an analysis of trust relationship on nodes, the visibility of nodes, and the homogeneity of systems. The output of the model can be used to estimate the severity of the worm dispersion effectively.
The social media response to Black Lives Matter: how Twitter users interact with Black Lives Matter through hashtag use

ABSTRACT This paper focuses on the social media presence of Black Lives Matter (BLM). Specifically, we examine how social media users interact with BLM by using hashtags and thus modify the framing of the movement. We call this decentralized interaction with the movement “distributed framing”. Empirically, we illustrate this idea with an analysis of 66,159 tweets that mention #BlackLivesMatter in 2014, when #BlackLivesMatter becomes prominent on social media. We also tally the other hashtags that appear with #BlackLivesMatter in order to measure how online communities influence the framing of the movement. We find that #BlackLivesMatter is associated with five types of hashtags. These hashtags mention solidarity or approval of the movement, refer to police violence, mention movement tactics, mention Ferguson, or express counter-movement sentiments. The paper concludes with hypotheses about the development of movement framings that can be addressed in future research.
