Out-of-domain FrameNet Semantic Role Labeling

Domain dependence of NLP systems is one of the major obstacles to their application in large-scale text analysis, also restricting the applicability of FrameNet semantic role labeling (SRL) systems. Yet, current FrameNet SRL systems are still only evaluated on a single in-domain test set. For the first time, we study the domain dependence of FrameNet SRL on a wide range of benchmark sets. We create a novel test set for FrameNet SRL based on user-generated web text and find that the major bottleneck for out-of-domain FrameNet SRL is the frame identification step. To address this problem, we develop a simple, yet efficient system based on distributed word representations. Our system closely approaches the state-of-the-art in-domain while outperforming the best available frame identification system out-of-domain. We publish our system and test data for research purposes.
Determinants of Prosocial Behavior in Included Versus Excluded Contexts

Prosocial behavior (PSB) is increasingly becoming necessary as more and more individuals experience exclusion. In this context it is important to understand the motivational determinants of PSB. Here we report two experiments which analyzed the influence of dispositional (prosocialness; rejection sensitivity) and motivational variables (prosocial self-efficacy; prosocial collective efficacy; trust; anger; social affiliation motivation) on PSB under neutral contexts (Study 1), and once under inclusion or exclusion conditions (Study 2). Both studies provided evidence for the predicted mediation of PSB. Results in both neutral and inclusion and exclusion conditions supported our predictive model of PSB. In the model dispositional variables predicted motivational variables, which in turn predicted PSB. We showed that the investigated variables predicted PSB; this suggests that to promote PSB one could (1) foster prosocialness, prosocial self and collective efficacy, trust in others and affiliation motivation and (2) try to reduce negative feelings and the tendency to dread rejection in an attempt to reduce the negative impact that these variables have on PSB. Moreover, the few differences that emerged in the model between the inclusion and exclusion contexts suggested that in interventions with excluded individuals special care emphasis should be placed on addressing rejection sensitivity and lack of trust.
Detecting complex events in user-generated video using concept classifiers

Automatic detection of complex events in user-generated videos (UGV) is a challenging task due to its new characteristics differing from broadcast video. In this work, we firstly summarize the new characteristics of UGV, and then explore how to utilize concept classifiers to recognize complex events in UGV content. The method starts from manually selecting a variety of relevant concepts, followed by constructing classifiers for these concepts. Finally, complex event detectors are learned by using the concatenated probabilistic scores of these concept classifiers as features. Further, we also compare three different fusion operations of probabilistic scores, namely Maximum, Average and Minimum fusion. Experimental results suggest that our method provides promising results. It also shows that Maximum fusion tends to give better performance for most complex events.
Assessing Consumers' Intention to Adopt Mobile Internet Services in the Kingdom of Saudi Arabia

This study was conducted with intention to provide a further understanding about the most predictive factors that could shape the customers’ intention to adopt Mobile Internet services in the Kingdom of Saudi Arabia. Thus, and according to critical reviewing of the main body of literature over the relevant area, researchers were able to identify four main factors that could have impact on the behavioural intention. These factors are performance expectancy, effort expectancy, hedonic motivation, and awareness that all are proposed in the same conceptual model of the current study. The current study data was collected from three main cities in Saudi Arabia (Jeddah, Riyadh and Dammam). Then structural equation modelling using AMOS was adopted to examine the proposed model and verify the research hypotheses. Statistical results largely supported the factors included as all of these factors have a significant influence on the customers’ intention to adopt Mobile Internet services. Hopefully, such results will provide accurate clues for designers and practitioners to focus more on the most important aspects that attract attention from customers in the Kingdom of Saudi Arabia.
APPENDIX to Stabilizing Performance in Many-Server Queues with Time-Varying Arrivals and Customer Feedback

Analytical approximations are developed to determine staffing levels that stabilize performance at designated targets in a many-server queueing model with time-varying arrival rates, customer feedback and abandonment. To provide a flexible model that can be readily fit to system data, Markovian routing is not assumed. Instead, the model has Bernoulli routing, with at most finitely many feedbacks, where the feedback probabilities, service-time and patience distributions all may depend on the visit number. Before returning to receive a new service, the fed-back customers experience delays in an infinite-server or finite-capacity queue, where the parameters may again depend on the visit number. A many-server heavy-traffic FWLLN shows that the performance targets are achieved asymptotically as the scale increases. A new refined modified-offered-load approximation is developed to obtain good results with low waiting-time targets. Simulation experiments confirm that the approximations are effective
Relation of Body Mass Index With Adverse Outcomes Among Patients With Atrial Fibrillation: A Meta‐Analysis and Systematic Review

Background Several studies have investigated the impact of body mass index (BMI) on the prognosis of atrial fibrillation, but the results remain controversial. We sought to estimate the association of BMI with atrial fibrillation–related outcomes. Methods and Results We systematically searched the Cochrane Library, PubMed, and Elsevier databases for all studies reporting associations between BMI and atrial fibrillation–related outcomes. Relative risks (RRs) and 95% CIs were extracted and pooled. Nine studies with 49 364 participants were included. Underweight BMI was associated with an increased risk of stroke or systemic embolism (RR 1.67, 95% CI 1.12–2.49), all‐cause mortaliity (RR 2.61, 95% CI 2.21–3.09), and cardiovascular death (RR 2.49, 95% CI 1.38–4.50). Nevertheless, the pooled RRs of overweight and obese patients were lower than those of normal‐weight patients for stroke or systemic embolism (overweight: RR 0.91, 95% CI 0.80–1.04; obese: RR 0.84, 95% CI 0.72–0.98; grade 1 obesity: RR 0.89, 95% CI 0.71–1.11; grade 2 obesity: RR 0.64, 95% CI 0.45–0.91; grade 3 obesity: RR 0.82, 95% CI 0.54–1.25), all‐cause death (overweight: RR 0.78, 95% CI 0.62–0.96; obese: RR 0.84, 95% CI 0.64–1.10; grade 1 obesity: RR 0.64, 95% CI 0.57–0.73; grade 2 obesity: RR 0.70, 95% CI 0.47–1.03; grade 3 obesity: RR 0.72, 95% CI 0.59–0.88), and cardiovascular death (overweight: RR 0.79, 95% CI 0.58–1.08; obese: RR 0.99, 95% CI 0.79–1.24). Conclusions Underweight BMI is associated with an increased risk of stroke or systemic embolism, cardiovascular death, and all‐cause death in Asian patients with atrial fibrillation, whereas in all atrial fibrillation patients, overweight and obese BMI was not associated with increased risks of these outcomes.
Supporting Teacher Orchestration in Ubiquitous Learning Environments: A Study in Primary Education

During the last decades, educational contexts have transformed into complex technological and social ecologies, with mobile devices expanding the scope of education beyond the traditional classroom, creating so-called Ubiquitous Learning Environments (ULEs). However, these new technological opportunities entail an additional burden for teachers, who need to manage and coordinate the resources involved in such complex educational scenarios in a process known as “orchestration”. This paper presents the evaluation of the orchestration support provided by GLUEPS-AR, a system aimed to help teachers in the coordination of across-spaces learning situations carried out in ULEs. The evaluation, following an interpretive research perspective, relied on a study where a pre-service teacher designed and enacted an authentic across-spaces learning situation in a primary school. The situation, which illustrates the orchestration challenges of ULEs, was aimed at fostering orienteering skills. It spanned five sessions taking place in the classroom, in the school's playground and at a nearby park, using multiple technologies and devices. The evaluation showed that GLUEPS-AR helped the teacher in the multiple aspects of orchestration, including implementation of his pedagogical ideas, adaptation in runtime, and sharing of orchestration load with students. Teacher awareness during outdoor activities was the main aspect to improve upon.
Structural Biology Communications Crystallization and Preliminary X-ray Diffraction Analysis of Yidc, a Membrane-protein Chaperone and Insertase from Bacillus Halodurans

YidC, a member of the YidC/Oxa1/Alb3 family, inserts proteins into the membrane and facilitates membrane-protein folding in bacteria. YidC plays key roles in both Sec-mediated integration and Sec-independent insertion of membrane proteins. Here, Bacillus halodurans YidC2, which has five transmembrane helices conserved among the other family members, was identified as a target protein for structure determination by a fluorescent size-exclusion chromatography analysis. The protein was overexpressed, purified and crystallized in the lipidic cubic phase. The crystals diffracted X-rays to 2.4 A ˚ resolution and belonged to space group P2 1 , with unit-cell parameters a = 43.9, b = 60.6, c = 58.9 A ˚ , = 100.3. The experimental phases were determined by the multiwavelength anomalous diffraction method using a mercury-derivatized crystal.
The Location of the UK Cotton Textiles Industry in 1838: A Quantitative Analysis

We examine the geography of cotton textiles in Britain in 1838 to test claims about why the industry came to be so heavily concentrated in Lancashire. Our analysis considers both first and second nature aspects of geography including the availability of water power, humidity, coal prices, market access, and sunk costs. We show that some of these characteristics have substantial explanatory power. Moreover, we exploit the change from water to steam power to show that the persistent effect of first nature characteristics on industry location can be explained by a combination of sunk costs and agglomeration effects.
Resistance Status of House Flies (Diptera: Muscidae) from Southeastern Nebraska Beef Cattle Feedlots to Selected Insecticides

Abstract The status of resistance to three insecticides (permethrin, stirofos, and methoxychlor), relative to a laboratory-susceptible colony, was evaluated in field populations of house flies, Musca domestica L. , collected from two beef cattle feedlots in southeastern Nebraska. Topical application and residual exposure to treated glass surfaces were suitable methods for determining the resistance status of house flies to permethrin, stirofos, or methoxychlor. However, in most cases, residual exposure was more sensitive in resistance detection (i.e., higher resistance ratios). The field populations tested were moderately resistant to permethrin (RR = 4.9-fold and RR = 7.3-fold, for topical application and residual exposure, respectively) and extremely resistant to stirofos and methoxychlor (not accurately quantifiable because of low mortality at the highest possible concentrations or doses). Probable explanations for the resistance status of these house fly populations and implications for global feedlot fly management are discussed.
Evaluation of Cytotoxicity and Genotoxicity of Inula viscosa Leaf Extracts with Allium Test

I. viscosa has been used for years in folk medicine for its anti-inflammatory, antipyretic, antiseptic, and paper antiphlogistic activities. In this study, cytotoxic and genotoxic effects of I. viscosa leaf extracts on the root meristem cells of Allium cepa have been examined. Onion bulbs were exposed to 2.5 mg/ml, 5 mg/ml, and 10 mg/ml concentrations of the extracts for macroscopic and microscopic analysis. Tap water has been used as a negative control and Ethyl methanesulfonate (EMS) (2 · 10−2 M) has been used as a positive control. The test concentrations have been determined according to doses which are recommended for use in alternative medicine. There has been statistically significant (P < .05) inhibition of root growth depending on concentration by the extracts when compared with the control groups. All the tested extracts have been observed to have cytotoxic effects on cell division in A. cepa. I. viscosa leaf extract induces the total number of chromosomal aberrations and micronuclei (MNC) formations in A. cepa root tip cells significantly when compared with control groups. Also, this paper shows for the first time the induction of cell death, ghost cells, cells with membrane damage, and binucleated cells by extract treatment. These results suggest the cytotoxic and genotoxic effects of the I. viscosa leaf extracts on A. cepa.
Q of the Earth

Regional body wave and surface wave studies indicate that there is a low-Q upper mantle layer underlying a high-Q lithosphere. Great circle surface wave attenuation is used to refine the Q structure of the upper mantle and to demonstrate that these features are consistent with the global data. Body wave results are used to constrain the average Q of various regions of the mantle and core and the Q gradient in the lower mantle. Normal mode data are used to test the hypotheses that bulk dissipation is not required in the mantle and that the inner core has low Q. Both hypotheses are consistent with the data. The data are also consistent with a smooth increase of Q with depth over most of the lower mantle and a low-Q zone at the base of the mantle. The radial modes require bulk dissipation somewhere in the earth, probably in the inner core. A series of parametric models is presented which illustrate the sensitivity of the attenuation data to major features of the Q distribution.
TETRIS: Scalable and Efficient Neural Network Acceleration with 3D Memory

The high accuracy of deep neural networks (NNs) has led to the development of NN accelerators that improve performance by two orders of magnitude. However, scaling these accelerators for higher performance with increasingly larger NNs exacerbates the cost and energy overheads of their memory systems, including the on-chip SRAM buffers and the off-chip DRAM channels. This paper presents the hardware architecture and software scheduling and partitioning techniques for TETRIS, a scalable NN accelerator using 3D memory. First, we show that the high throughput and low energy characteristics of 3D memory allow us to rebalance the NN accelerator design, using more area for processing elements and less area for SRAM buffers. Second, we move portions of the NN computations close to the DRAM banks to decrease bandwidth pressure and increase performance and energy efficiency. Third, we show that despite the use of small SRAM buffers, the presence of 3D memory simplifies dataflow scheduling for NN computations. We present an analytical scheduling scheme that matches the efficiency of schedules derived through exhaustive search. Finally, we develop a hybrid partitioning scheme that parallelizes the NN computations over multiple accelerators. Overall, we show that TETRIS improves mthe performance by 4.1x and reduces the energy by 1.5x over NN accelerators with conventional, low-power DRAM memory systems.
Histochemistry and electron microscopy of the three cell types in the adrenal gland of the frog

The microscopic structure of the frog adrenal gland has been studied by several investigators. A majority agree that there are 4 cell types: cells rich in lipide, chromaffin cells, eosinophilic cells and occasional ganglion cells. The cells that contain large numbers of lipide droplets appear to correspond functionally to the cortical tissue of the mammalian adrenal. In recognition of this physiological relationship, these cells will be called “cortical cells” hereafter? but the reader should bear in mind that the term does not imply that there is a cortico-medullary histological organization in the frog adrenal. The chromaffin cells of the frog are similar to those of other animal species, but the eosinophilic cells seem to have no counterpart in the mammalian adrenal gland and there is great divergence of opinion concerning their origin and functional significance. Stilling (1898) believed that they were present in appreciable numbers only in the warm months of the year and referred to them as the ‘‘summer cells. ” Grynfeltt (’04) and Radu (’31) both regarded these cells as modified basophilic leukocytes present as “wandering cells ”
Hyperstrong Radio-Wave Scattering in the Galactic Center. II. A Likelihood Analysis of Free Electrons in the Galactic Center

The scattering diameters of Sgr A* and several nearby OH masers (≈ 1'' at 1 GHz) indicate that a region of enhanced scattering is along the line of sight to the Galactic center. We combine radio-wave scattering data and free-free emission and absorption measurements in a likelihood analysis that constrains the following parameters of the GC scattering region: The GC-scattering region separation, ΔGC; the angular extent of the region, ψℓ and ψb; the outer scale on which density fluctuations occur, l0; and the gas temperature, Te. The maximum likelihood estimates of these parameters are ΔGC=133−80+200 pc, 0. °5≤ψℓ≲1°, and (l0/1 pc)2/3Te−1/2=10-7±0.8 . The parameter ψb was not well constrained, and we adopt ψb = 0. °5. The close correspondence between ΔGC and ψℓ DGC suggests that the scattering region encloses the GC. As host media for the scattering, we consider the photoionized surface layers of molecular clouds and the interfaces between molecular clouds and the 107 K ambient gas. We are unable to make an unambiguous determination, but we favor the interface model in which the scattering medium is hot (Te ~ 106 K) and dense (ne ~ 10 cm-3). The GC scattering region produces a 1 GHz scattering diameter for an extragalactic source of 90'', if the region is a single screen, or 180'', if the region wraps around the GC, as appears probable. We modify the Taylor-Cordes model for the Galactic distribution of free electrons in order to include an explicit GC component. We predict that pulsars seen through this region will have a dispersion measure of approximately 2000 pc cm-3, of which approximately 1500 pc cm-3 arises from the GC component itself. We stress the uniqueness of the GC scattering region, probably resulting from the high-pressure environment in the GC.
Multiple stiffening effects of nanoscale knobs on human red blood cells infected with Plasmodium falciparum malaria parasite

Significance Our coarse-grained molecular dynamics (CGMD) simulations show that the deposition of nanoscale knobs, rather than spectrin network remodeling, is the primary cause of the dramatically increased stiffness of the Plasmodium falciparum (Pf)-infected red blood cell (RBC) membranes. Our analyses further reveal that the knobs stiffen the RBC membrane in a unique manner by simultaneously harnessing composite strengthening, strain hardening, and knob density-dependent vertical coupling effects. In addition to providing a fundamental understanding of the stiffening mechanism of Pf-infected RBCs, our simulation results suggest potential targets for antimalarial therapies. During its asexual development within the red blood cell (RBC), Plasmodium falciparum (Pf), the most virulent human malaria parasite, exports proteins that modify the host RBC membrane. The attendant increase in cell stiffness and cytoadherence leads to sequestration of infected RBCs in microvasculature, which enables the parasite to evade the spleen, and leads to organ dysfunction in severe cases of malaria. Despite progress in understanding malaria pathogenesis, the molecular mechanisms responsible for the dramatic loss of deformability of Pf-infected RBCs have remained elusive. By recourse to a coarse-grained (CG) model that captures the molecular structures of Pf-infected RBC membrane, here we show that nanoscale surface protrusions, known as “knobs,” introduce multiple stiffening mechanisms through composite strengthening, strain hardening, and knob density-dependent vertical coupling. On one hand, the knobs act as structural strengtheners for the spectrin network; on the other, the presence of knobs results in strain inhomogeneity in the spectrin network with elevated shear strain in the knob-free regions, which, given its strain-hardening property, effectively stiffens the network. From the trophozoite to the schizont stage that ensues within 24–48 h of parasite invasion into the RBC, the rise in the knob density results in the increased number of vertical constraints between the spectrin network and the lipid bilayer, which further stiffens the membrane. The shear moduli of Pf-infected RBCs predicted by the CG model at different stages of parasite maturation are in agreement with experimental results. In addition to providing a fundamental understanding of the stiffening mechanisms of Pf-infected RBCs, our simulation results suggest potential targets for antimalarial therapies.
Recombinant basic fibroblast growth factor stimulates wound healing in healing-impaired db/db mice

The stimulatory effect of recombinant basic fibroblast growth factor (bFGF) on wound healing was assessed using healing-impaired (db/db) mice. Full-thickness wounds were made in female diabetic C57BL/KsJ db/db mice, and their normal (db/+) littermates with a punch biopsy instrument. Recombinant bFGF was applied locally to the open wound once a day. The mice were later killed and histological sections of the wounds were prepared. The degree of wound healing was evaluated using several histological parameters such as degree of reepithelialization, granulation tissue thickness, matrix density, number of infiltrated cells, and number of capillaries. Wounds from normal mice displayed good reepithelialization rates and granulation tissue formation, while wounds from db/db mice had poor responses, especially in the dermal parameters. Although the application of bFGF to wounds in the normal (db/+) mice had little effect, application of bFGF to wounds in db/db mice induced significant responses in all of the dermal parameters compared with nontreated db/db mice (p less than 0.001). In the presence of bFGF, these parameters approximated those observed in nontreated littermates. A minimum of 0.5 microgram bFGF in either single or multiple applications was required for a significant effect. bFGF that was either boiled or pretreated with neutralizing antibody had little stimulatory effect. Time-course experiments indicated that the granulation response in bFGF-treated mice peaked between 8 and 12 d, and decreased after 12 d, while matrix density continued to increase until the 18th day (p less than 0.05). The breaking strength of healed linear wounds in db/db mice was also decreased when compared with heterozygous littermates. This parameter was also improved by the administration of bFGF to the wounds (p less than 0.05).
