Building a Graded Chinese Sentiment Dictionary Based on Commonsense Knowledge for Sentiment Analysis of Song Lyrics

With the rise of social media, sentiment analysis has become a popular research field in recent years. Sentiment dictionaries are vital for this task; however, there are few available in Chinese. Translated English sentiment dictionaries are often inaccurate or lacking vocabulary. Moreover, many dictionaries provide only binary polarity values or no values at all. In this paper, we integrate several common sentiment dictionaries into a larger dictionary. We then describe an algorithm that can extrapolate sentiment values for the empty entries in this dictionary from the annotated ones using the relationships in Chinese ConceptNet. The resulting iSentiDictionary is a Chinese sentiment dictionary with 28,248 concepts annotated with sentiment values. To test our dictionary, we construct a dictionary-based song lyrics sentiment analysis system. We compare performance of iSentiDictionary with that of three translated sentiment dictionaries: ANEW, SenticNet and SentiWordNet. Experimental results show that using iSentiDictionary achieves the best results in terms of both Word Coverage and Absolute Sentiment Error. We believe this is because of iSentiDictionary’s high word coverage for Mandarin pop songs.
The Stigma of a Mental Illness Label: Attitudes Towards Individuals with Mental Illness

The present study examined whether stigma toward individuals with mental illness will evidence itself in job performance evaluations. To enhance this potential effect of mental illness stigma, an additional “difference” of race was included as a factor that may affect perception of functioning and attitude towards the individual with a mental illness diagnosis. Additionally, general professed attitudes towards mental illness and direct attitudes when one is exposed to an individual with a mental illness diagnosis were considered. Participants were drawn from the undergraduate population of a midsize private university and responded to three questionnaires after viewing a video clip of an individual experiencing a moderately stressful day at work. Half the participants were given the information that the individual they viewed was undergoing treatment for a mental illness, and the other half were not given this information. Some of the participants viewed an actor of the same race, while the others viewed an actor of a different race. Data were analyzed by condition and race. The results of this study did not support the hypotheses. Contrary to expectations, information that the actor had been diagnosed with a mental illness did not influence job ratings or attitudes toward mental illness. Similarly, results indicated that participants' evaluations were not affected by similarities and differences in the races of the observed and the observer. Finally, attitudes to mental illness generally did predict participants' direct attitudes toward an individual who was presented as having a mental illness. Prior contact and experience with individuals with mental illness did not moderate these results. Possible explanations for the outcome of the study are discussed.
Concept Representation with Overlapping Feature Intervals

This article presents a new form of exemplar-based learning method, based on overlapping feature intervals. In this model, a concept is represented by a collection of overlappling intervals for each feature and class. Classification with Overlapping Feature Intervals COFI is a particular implementation of this technique. In this incremental, inductive, and supervised learning method, the basic unit of the representation is an interval. The COFI algorithm learns the projections of the intervals in each feature dimension for each class. Initially, an interval is a point on a feature-class dimension; then it can be expanded through generalization. No specialization of intervals is done on feature-class dimensions by this algorithm. Classification in the COFI algorithm is based on a majority voting among the local predictions that are made individually by each feature. An evaluation of COFI and its comparison with similar other classification techniques is given.
Modulation of Neural Plasticity as a Basis for Stroke Rehabilitation

Current understanding of the mechanisms underlying neural plasticity changes after stroke stems from experimental models as well as clinical studies and provides the foundation for evidence-based neurorehabilitation. In this review, we first describe the main structural and functional constituents of neural plasticity that are believed to contribute to recovery of function after stroke. Next, we discuss selected behavioral manipulations and adjuvant therapies that can stimulate neural plasticity and improve recovery of function, particularly when applied in combination with task-specific physiotherapy and in a stimulating environment. ### Experience-Dependent Plasticity of the Cerebral Cortex Cerebral cortex is an assembly of neuronal cells that are highly interconnected. The morphology as well as function of these complex and spatially distributed networks are modulated or even controlled by the glial component of the central nervous system (CNS). The ability to adapt in response to the changing environment is the most fundamental property of the nervous tissue and constitutes the basis for learning. Neural plasticity is the neurobiological basis for the ability to adapt and learn in an experience-dependent manner.1 At the structural level, neural plasticity could be defined in terms of dendritic and axonal arborization, spine density, synapse number and size, receptor density, and in some brain regions also the number of neurons. These structural constituents of neural plasticity jointly determine the complexity of neuronal networks and their activity and contribute to recovery of function after stroke and other CNS injury. ### Spontaneous Recovery of Function After Stroke Loss of function attributable to stroke is caused by cell death in the infarcted region as well as cell dysfunction in the areas surrounding the infarct. In addition, the function of remote brain regions, including the contralateral areas that are connected to the area of tissue damage, is compromised because of hypometabolism, neurovascular uncoupling, and aberrant neurotransmission, jointly called diaschisis.1 Some recovery of function occurs spontaneously after stroke in …
Peak Power Scaling Of Nanosecond Pulses In Thulium Based Fiber Lasers

Thulium based fiber lasers represent a promising alternative for pulse energy scaling and high peak power generation with ytterbium based systems at 1μm. Advantages of thulium arise from the operation at longer wavelengths and a large gain bandwidth (1.8-2.1μm). Nonlinear effects, such as self phase modulation, stimulated Raman scattering and stimulated Brillouin scattering generally limit peak power scaling in fiber lasers. The longer wavelength of thulium fiber lasers and large mode field areas can significantly increase the nonlinear thresholds. Compared to 1μm systems, thulium fiber lasers enable single mode guidance for two times larger mode field diameter in step index fibers. Similar behavior is expected for index guiding thulium doped photonic crystal fibers. In this work a novel thulium doped rod type photonic crystal fiber design with large mode field diameter (> 50μm) was first characterized in CW-lasing configuration and then utilized as final amplifier in a two stage master oscillator power amplifier. The system generated MW-level peak power at 6.5ns pulse duration and 1kHz repetition rate. This world record performance exemplifies the potential of thulium fiber lasers to supersede ytterbium based systems for very high peak power generation in the future. As part of this work a computer model for the transient simulation of pulsed amplification in thulium based fiber lasers was developed. The simulations are in good agreement with the experimental results. The computer model can be used for efficient optimization of future thulium based fiber amplifier designs.
Modelling of the reservoir effect on electromigration lifetime

Electromigration behaviour in W-plug/metal stripe structures is different from conventional metal-strip structures because there is a blocking boundary formed by the immobile W-plug in the contact/via. Electromigration failures occur more readily close to the W-plug than in metal-strip structures because metal ions are forced away from the contacts/vias by electric current, blocking the contacts/vias area. Several works have reported electromigration lifetime of multiple level interconnects to be influenced by the presence of a reservoir around the contacts/vias. Reservoirs are metal parts that are not or are hardly conducting current that act as a source to provide atoms for the area around the blocking boundary where the atoms migrate away due to the electric current. Interconnect lifetime can be prolonged by using the reservoirs, called the "reservoir effect". 2D simulation of the effects of reservoirs has been performed. The stress build-up during electromigration in the contact area can be simulated for several configurations, separating the effects of overlap, total reservoir area, the reservoir layout directions (vertical and horizontal), number of contacts/vias and contact/via placement. It is very useful for IC design rules to estimate which parameters are important for IC reliability. In this study, we considered the critical stress that the metal line can sustain before void formation as failure criterion. The failure time is determined by the time to reach the critical stress.
Activation of mechanosensitive currents in traumatized membrane

Wan, Xiaodong, Peter Juranka, and Catherine E. Morris. Activation of mechanosensitive currents in traumatized membrane. Am. J. Physiol. 276 (Cell Physiol. 45): C318–C327, 1999. —Mechanosensitive (MS) channels, ones whose open probability varies with membrane tension in patch recordings, are diverse and ubiquitous, yet many are remarkably insensitive to mechanical stimuli in situ. Failure to elicit mechanocurrents from cells with abundant MS channels suggests that, in situ, the channels are protected from mechanical stimuli. To establish what conditions affect MS channel gating, we monitored Lymnaea neuron stretchactivated K (SAK) channels in cell-attached patches after diverse treatments. Mechanosensitivity was gauged by rapidity of onset and extent of channel activation during a step pressure applied to a ‘‘naive’’ patch. The following treatments enhanced mechanosensitivity: actin depolymerization (cytochalasin B), N-ethylmaleimide, an inhibitor ofATPases including myosin, elevated Ca (using A-23187), and osmotic swelling (acutely and after 24 h). Osmotic shrinking decreased mechanosensitivity. A unifying interpretation is that traumatized cortical cytoskeleton cannot prevent transmission of mechanical stimuli to plasma membrane channels. Mechanoprotection and capricious mechanosensitivity are impediments to cloning efforts with MS channels. We demonstrate a potpourri of endogenous MS currents from L-M(TK2) fibroblasts; others had reported these cells to be MS current null and hence to be suitable for expressing putative MS channels.
Hints on the evolutionary design of a dimeric RNase with special bioactions

Residues P19, L28, C31, and C32 have been implicated (Di Donato A, Cafaro V, D'Alessio G, 1994, J Biol Chem 269:17394–17396; Mazzarella L, Vitagliano L, Zagari A, 1995, Proc Natl Acad Sci USA: forthcoming) with key roles in determining the dimeric structure and the N‐terminal domain swapping of seminal RNase. In an attempt to have a clearer understanding of the structural and functional significance of these residues in seminal RNase, a series of mutants of pancreatic RNase A was constructed in which one or more of the four residues were introduced into RNase A. The RNase mutants were examined for: (1) the ability to form dimers; (2) the capacity to exchange their N‐terminal domains; (3) resistance to selective cleavage by subtilisin; and (4) antitumor activity. The experiments demonstrated that: (1) the presence of intersubunit disulfides is both necessary and sufficient for engendering a stably dimeric RNase; (2) all four residues play a role in determining the exchange of N‐teminal domains; (3) the exchange is the molecular basis for the RNase antitumor action; and (4) this exchange is not a prerequisite in an evolutionary mechanism for the generation of dimeric RNases.
Array calibration method for gain-phase errors based on asynchronous interstation direct wave interference

: In this paper, we analyze the interstation direct wave interference (IDWI) under an asynchronous condition. We propose an array calibration method for the consistency of gain-phase for the ﬁrst time and show the conditions and probability of the generation of IDWI and the characteristics of asynchronous IDWI. This method can implement calibration of direct wave without keeping radar stations in synchronous condition and perform outstanding precision and stability. The experimental data demonstrate that using array calibration for gain-phase errors based on asynchronous IDWI can get accurate and stable calibration values of gain-phase errors.
Bacterial biofilms in a ‘genes‐to‐ecosystems’ context

In ecology, there is an increasing amount of research dedicated to understanding how intraspecific genetic diversity can extend beyond the population level to influence the assembly of communities and the functioning of ecosystems. In this issue of Molecular Ecology, Koh et al. (2012) take this exploration to a new level using bacterial biofilms and protozoan grazers. They show that there is heritable variation in the phenotypes of different variants of biofilms of Serratia marcescens and that these strains display complementarity when combined in a diverse assemblage. Mixtures of variants were significantly more resistant to protozoan grazing than either wild‐type or variant biofilms grown in monocultures. While similar biodiversity effects of genotype mixtures have been observed in other systems, Koh et al. (2012) link phenotype variation of the biofilms to a single nucleotide polymorphism in one regulatory gene. Importantly, the authors demonstrate that minimal changes in a genotype can result in substantial shifts in interspecific ecological interactions.
On Packet-Level Non-Altruistic Node Cooperation in Wireless Networks

In this paper, we investigate packet-level non-altruistic node cooperation in wireless networks with regenerative nodes. Since each node has its own data to transmit, pure relays do not exist. We prove that the split of transmit power has no impact on the diversity performance of non-altruistic cooperative transmissions. Despite the beneficial diversity gain, our results show that non-altruistic cooperative transmissions are not always superior to ordinary direct transmissions. We also evaluate the performance gains due to beneficial packet-level node cooperations in a multi-node wireless network. Simulation results show that favorable packet-level cooperative transmissions provide a substantial gain over ordinary direct transmissions.
Are responses of herbivores to environmental variability spatially consistent in alpine ecosystems?

Animal responses to global climate variation might be spatially inconsistent. This may arise from spatial variation in factors limiting populations' growth or from differences in the links between global climate patterns and ecologically relevant local climate variation. For example, the North Atlantic Oscillation (NAO) has a spatially consistent relation to temperature, but inconsistent spatial relation to snow depth in Scandinavia. Furthermore, there are multiple mechanistic ways by which climate may limit animal populations, involving both direct effects through thermoregulation and indirect pathways through trophic interactions. It is conceptually appealing to directly model the predicted mechanistic links. This includes the use of climate variables mimicking such interactions, for example, to use growing degree days (GDD) as a proxy for plant growth rather than average monthly temperature. Using a unique database of autumn body mass of 83331 domestic lambs from the period 1992–2007 in four alpine ranges in Norway, we demonstrate the utility of hierarchical, mechanistic path models fitted using a Bayesian approach to analyse explicitly predicted relationships among environmental variables and between lamb body mass and the environmental variables. We found large spatial variation in strength of responses of autumn lamb body mass to the NAO, to a proxy for plant growth in spring (the Normalized Difference Vegetation Index, NDVI) and effects even differed in direction to local summer climate. Average local temperature outperformed GDD as a predictor of the NDVI, whereas the NAO index in two areas outperformed local weather variables as a predictor of lamb body mass, despite the weaker mechanistic link. Our study highlights that spatial variation in strength of herbivore responses may arise from several processes. Furthermore, mechanistically more appealing measures do not always increase predictive power due to scale of measurement and since global measures may provide more relevant “weather packages” for larger scales.
VHL Promotes E2 Box-Dependent E-Cadherin Transcription by HIF-Mediated Regulation of SIP1 and Snail

ABSTRACT The product of the von Hippel-Lindau gene (VHL) acts as the substrate-recognition component of an E3 ubiquitin ligase complex that ubiquitylates the catalytic α subunit of hypoxia-inducible factor (HIF) for oxygen-dependent destruction. Although emerging evidence supports the notion that deregulated accumulation of HIF upon the loss of VHL is crucial for the development of clear-cell renal cell carcinoma (CC-RCC), the molecular events downstream of HIF governing renal oncogenesis remain unclear. Here, we show that the expression of a homophilic adhesion molecule, E-cadherin, a major constituent of epithelial cell junctions whose loss is associated with the progression of epithelial cancers, is significantly down-regulated in primary CC-RCC and CC-RCC cell lines devoid of VHL. Reintroduction of wild-type VHL in CC-RCC (VHL−/−) cells markedly reduced the expression of E2 box-dependent E-cadherin-specific transcriptional repressors Snail and SIP1 and concomitantly restored E-cadherin expression. RNA interference-mediated knockdown of HIFα in CC-RCC (VHL−/−) cells likewise increased E-cadherin expression, while functional hypoxia or expression of VHL mutants incapable of promoting HIFα degradation attenuated E-cadherin expression, correlating with the disengagement of RNA polymerase II from the endogenous E-cadherin promoter/gene. These findings reveal a critical HIF-dependent molecular pathway connecting VHL, an established “gatekeeper” of the renal epithelium, with a major epithelial tumor suppressor, E-cadherin.
Inkjet-printing rapid prototyping of a robust and flexible capacitive touch panel

In this work we present an inkjet-printed capacitive touch panel working in single-ended or self-capacitance mode. We show that inkjet-printing enables manufacturing of low-cost, though robust, touch sensing devices. The evaluated structure is realized as interlocking diamonds topology. Its robustness against undesired objects present at the sensor surface is demonstrated in different experimental setups such as application of water or metal to the sensor surface with simultaneous touch detection. The position resolution respos of the fabricated device is approximately 100 μm (≈ 250 dpi) and thus well comparable with or better than resolutions reached by similar devices.

The Prognostic Significance of Pretreatment Serum CEA Levels in Gastric Cancer: A Meta-Analysis Including 14651 Patients

Background Carcinoembryonic antigen (CEA) is commonly used as a serum tumor marker in clinical practice; however, its prognostic value for gastric cancer patients remains uncertain. This meta-analysis was performed to assess the prognostic value of CEA and investigate CEA as a tumor marker. Methods PubMed, EMBASE and other databases were searched for potentially eligible studies. Forty-one studies reporting the prognostic effect of pretreatment serum CEA expression in gastric cancer patients were selected. Data on 14651 eligible patients were retrieved for the meta-analysis. Based on the data extracted from the available literature, the hazard ratio (HR) and 95% confidence interval (CI) for an adverse prognosis were estimated for gastric cancer patients with elevated pretreatment serum levels of CEA (CEA+) relative to patients with normal pretreatment CEA levels (CEA-). Results The CEA+ patients had a significantly poorer prognosis than the CEA- patients in terms of overall survival (OS: HR 1.716, 95% CI 1.594 - 1.848, P< 0.001), disease-specific survival (DSS: HR 1.940, 95% CI 1.563 - 2.408, P< 0.001), and disease-free survival (DFS: HR 2.275, 95% CI 1.836 - 2.818, P< 0.001). Publication bias and an influence of different cut-off values were not observed (all P> 0.05). In the pooled analyses of multivariate-adjusted HRs, the results suggested that pretreatment serum CEA may be an independent prognostic factor in gastric cancer (OS: HR 1.681, 95% CI 1.425 - 1.982; DSS: HR 1.900, 95% CI 1.441 - 2.505; DFS: HR 2.579, 95% CI 1.935 - 3.436). Conclusion/Significance The meta-analysis based on the available literature supported the association of elevated pretreatment serum CEA levels with a poor prognosis for gastric cancer and a nearly doubled risk of mortality in gastric cancer patients. CEA may be an independent prognostic factor for gastric cancer patients and may aid in determining appropriate treatment which may preferentially benefit the CEA+ patients.
