Understanding Media Markets in the Digital Age: Economics and Methodology

Digitization raises a variety of important academic and managerial questions around firm strategies and public policies for the content industries, with many of these questions influenced by the erosion of copyright caused by Internet file-sharing. At the same time, digitization has created many new opportunities to empirically analyze these questions by leveraging new data sources and abundant natural experiments in media markets. In this chapter we describe the open "big picture" questions related to digitization and the copyright industries, and discuss methodological approaches to leverage the new data and natural experiments in digital markets to address these questions. We close our chapter with a specific proof of concept research study that analyzes an important academic and managerial question -- the impact of legitimate streaming services on the demand for piracy. We use ABC's decision to add its content to Hulu.com as a natural experiment and show that it resulted in an economically and statistically significant drop in piracy of that content.
M3A: Model, MetaModel, and Anomaly Detection in Web Searches

'Alice' is submitting one web search per five minutes, for three hours in a row - is it normal? How to detect abnormal search behaviors, among Alice and other users? Is there any distinct pattern in Alice's (or other users') search behavior? We studied what is probably the largest, publicly available, query log that contains more than 30 million queries from 0.6 million users. In this paper, we present a novel, user-and group-level framework, M3A: Model, MetaModel and Anomaly detection. For each user, we discover and explain a surprising, bi-modal pattern of the inter-arrival time (IAT) of landed queries (queries with user click-through). Specifically, the model Camel-Log is proposed to describe such an IAT distribution; we then notice the correlations among its parameters at the group level. Thus, we further propose the metamodel Meta-Click, to capture and explain the two-dimensional, heavy-tail distribution of the parameters. Combining Camel-Log and Meta-Click, the proposed M3A has the following strong points: (1) the accurate modeling of marginal IAT distribution, (2) quantitative interpretations, and (3) anomaly detection.
Supporting Temporal Query Processingby Hash

Hash lters are very useful for the optimization of query processing, especially in the case of join queries. In this paper, we investigate the possibilities how hash lters can be utilized in the eld of temporal queries. We introduce a exible kind of such hash lters and discuss diierent variations. Additionally , we analyze the usefulness of this concept for some well-known types of temporal queries.
PECAM-Independent Thioglycollate Peritonitis Is Associated With a Locus on Murine Chromosome 2

Background Previous studies have demonstrated that knockout or inhibition of Platelet/Endothelial Cell Adhesion Molecule (PECAM, CD31) in a number of murine strains results in impaired inflammatory responses, but that no such phenotype is seen in the C57BL/6 (B6) murine background. Methodology/Principal Findings We have undertaken a quantitative trait locus (QTL) mapping effort between FVB/n (FVB) and B6 mice deficient for PECAM to identify the gene or genes responsible for this unique feature of B6 mice. We have identified a locus on murine chromosome 2 at approximately 35.8 Mb that is strongly associated (LOD score = 9.0) with inflammatory responses in the absence of PECAM. Conclusions/Significance These data potentiate further study of the diapedesis machinery, as well as potential identification of new components of this machinery. As such, this study is an important step to better understanding the processes of inflammation.

Sensor-wise methodology to face NBTI stress of NoC buffers

Networks-on-Chip (NoCs) are a key component for the new many-core architectures, from the performance and reliability stand-points. Unfortunately, continuous scaling of CMOS technology poses severe concerns regarding failure mechanisms such as NBTI and stress-migration. Process variation makes harder the scenario, decreasing device lifetime and performance predictability during chip fabrication. This paper presents a novel cooperative sensor-wise methodology to reduce the NBTI degradation in the network on-chip (NoC) virtual channel (VC) buffers, considering process variation effects as well. The changes introduced to the reference NoC model exhibit an area overhead below 4%. Experimental validation is obtained using a cycle accurate simulator considering both real and synthetic traffic patterns. We compare our methodology to the best sensor-less round-robin approach used as reference model. The proposed sensor-wise strategy achieves up to 26.6% and 18.9% activity factor improvement over the reference policy on synthetic and real traffic patterns respectively. Moreover a net NBTI Vth saving up to 54.2% is shown against the baseline NoC that does not account for NBTI.
Web service schema matching based on invocation instance duplicates

Web service schema matching is the preliminary phase of service composition and service Mashup. With the entry of large numbers of services on the Internet, it will be difficult to find and suggest the most relevant service candidates for new composition and Mashup. Furthermore, the composition and Mashup candidates must be confirmed by manual work which is very inefficient and even inefficacious. In this work, we present an approach for web service schema matching based on service invocation instance duplicates. This approach predicts the schema relationship between web service parameters based on duplicates among invocation data sets and is very different from the syntactical-based and semantic-based matching approaches. It can be used for predicting and verifying service composition and Mashup candidates.
The Impact of a Schoolwide Mindfulness Program on Adolescent Well-Being, Stress, and Emotion Regulation: A Nonrandomized Controlled Study in a Naturalistic Setting

Few studies have explored large, school-wide mindfulness programs targeted at adolescents in naturalistic settings, while still including key design elements like control groups. The authors explored the impact of a six-week large-scale mindfulness program in a high school setting on adolescent participants’ subjective wellbeing, perceived stress, and emotion regulation. Participants were divided into control and treatment groups and completed pre- and post-tests on the various outcomes. Participation in the program was associated with a significant decline in perceived stress, although the effect size was small, potentially because of limitations associated with the naturalistic setting. Suggestions for future research linking mindfulness programs to adolescent mental health are discussed.
Proof Theory of a Multi-Lane Spatial Logic

We extend the Multi-lane Spatial Logic MLSL, introduced in previous work for proving the safety (collision freedom) of traffic maneuvers on a multi-lane highway, by length measurement and dynamic modalities. We investigate the proof theory of this extension, called EMLSL. To this end, we prove the undecidability of EMLSL but nevertheless present a sound proof system which allows for reasoning about the safety of traffic situations. We illustrate the latter by giving a formal proof for a lemma we could only prove informally before.
Thermodynamics of the Maxwell-Gauss-Bonnet anti-de Sitter black hole with higher derivative gauge corrections

The local and global thermal phase structure for asymptotically anti-de Sitter black holes charged under an abelian gauge group, with both Gauss-Bonnet and quartic field strength corrections, is mapped out for all parameter space. We work in the grand canonical ensemble where the external electric potential is held fixed. The analysis is performed in an arbitrary number of dimensions, for all three possible horizon topologies — spherical, flat or hyperbolic. For spherical horizons, new metastable configurations are exhibited both for the pure Gauss-Bonnet theory as well as the pure higher derivative gauge theory and combinations thereof. In the pure Gauss-Bonnet theory with negative coefficient and five or more spatial dimensions, two locally thermally stable black hole solutions are found for a given temperature. Either one or both of them may be thermally favored over the anti-de Sitter vacuum — corresponding to a single or a double decay channel for the metastable black hole. Similar metastable configurations are uncovered for the theory with pure quartic field strength corrections, as well combinations of the two types of corrections, in three or more spatial dimensions. Finally, a secondary Hawking-Page transition between the smaller thermally favored black hole and thermal anti-de Sitter space is observed when both corrections are turned on and their couplings are both positive.
Nucleotide and complete amino acid sequences of Kunjin virus: definitive gene order and characteristics of the virus-specified proteins.

A Kunjin (KUN) virus cDNA sequence of 10664 nucleotides was obtained and it encoded a single open reading frame for 3433 amino acids. Partial N-terminal amino acid analyses of KUN virus-specified proteins identified the polyprotein cleavage sites and the definitive gene order. The gene order relative to that proposed for yellow fever (YF) virus is as follows: KUN 5'-C.GP20. E.GP44. P19.P10. P71. (? ). P21.P98-3' YF 5'-C.prM. E.NS1. ns2a.ns2b. NS3.ns4a. ns4b. NS5-3'. The order of putative signal sequences and stop transfer sequences indicated that KUN NS1, NS2A and NS4B are probably cleaved in the lumen of the endoplasmic reticulum, at a consensus site Val-X-Ala decreases where X is an uncharged residue, and NS2B, NS3 and NS5 are cleaved in the cytosol at the site Lys-Arg decreases Gly. Comparisons with the complete amino acid sequences of YF and West Nile (WN) viruses showed that KUN virus shared 93% homology with WN virus, but only 46% homology with YF virus. Comparisons among individual gene products of six flaviviruses showed that E, NS1, NS3 and NS5 tended to be the most highly conserved, and C among the least conserved. Homologous cleavage sites were evident, and six domains in NS5, a total of over 170 residues, shared at least 85% homology. Comparisons with the KUN C to NS2B sequence defined a gradient of relationships of all gene products in decreasing order WN greater than Murray Valley greater than Japanese encephalitis greater than St Louis encephalitis viruses within this closely related serological complex. A non-coding 5' sequence (75 nucleotides) of KUN virus shared 95% homology with WN virus and a shorter imperfect match with Murray Valley encephalitis virus (15 of 18 nucleotides). The KUN non-coding 3' sequence of 290 nucleotides contained several short and imperfectly matched sequences, and shared 87% homology over the distal region of 191 nucleotides with the corresponding region of WN virus RNA.
Visualization of spatio-temporal data of bus trips

Bus is public means to travel in several cities. Traditional maps provide with the information of bus routes that passengers may use to design a travel from a place to another. It is difficult for them to obtain an appropriate route because of the lack of the information of time on the traditional maps. Some web sites enable passengers to take bus but they do not support passengers to have more diverse selections. In this paper, buses are considered as moving objects. Mathematically, movements of objects are the mappings (functions) from times to locations. In 3-D Cartesian coordinate systems, space-time cubes, which are called temporal maps in this paper, are models representing movements in spatio-temporal domain. A bus route on a traditional map is the curve connecting the spatial positions where the bus visits, from the departure station to the arrival. A bus trip is a bus route included time. It is represented on temporal maps. With the visualization of spatio-temporal data of bus trips on temporal maps, passengers may mark out bus trips for their more appropriate travels. This article implemented visualization tools for the design of bus travels on temporal maps.
Top-down visual selective attention model combined with bottom-up saliency map for incremental object perception

Humans can efficiently perceive arbitrary visual objects based on incremental learning mechanism and selective attention function. In this paper, we propose a new top-down attention model based on human visual attention mechanism, which considers both relative feature based bottom-up saliency and goal oriented top-down attention. The proposed model can generate top-down bias signals of form and color features for a specific object, which draw attention to find a desired object by an incremental learning mechanism together with object feature representation scheme. A growing fuzzy topology adaptive resonance theory (GFTART) model is proposed by adapting a growing cell structure (GCS) unit into a conventional fuzzy ART, by which the proliferation problem of the conventional fuzzy ART can be enhanced. The proposed GFTART plays two important roles for object color and form biased attention; one is to incrementally learn and memorize color and form features of arbitrary objects, and the other is to generate top-down bias signal for selectively attending to a target object. Experimental results show that the proposed model performs well in successfully focusing on given target objects, as well as incrementally perceiving arbitrary objects in natural scenes.
Design of Sequential Machines from Their Regular Expressions

Procedures are given to convert any regular expression into a state diagram description and neural net realization of a machine that recognizes the regular set of sequences described by the given expression. It is established that any regular expression with a finite number of connectives describes a regular set of sequences that can be recognized by a finite state machine. All the procedures given are guaranteed to terminate in a finite number of steps, and a generalized computer program can be written to handle the entire conversion. An incidental result of the theory is the design of multiple output sequential machines. The potential usefulness of regular expressions and a long neglected form of a state diagram are demonstrated.
Research on Efficiency Evaluation for Steganalysis

A novel benchmark for efficiency evaluation of steganalysis is presented in this paper. The efficiency metric reflects the detection accuracy of steganalysis, which is an important index to evaluate the performance of steganalysis schemes. The main idea is to evaluate efficiency in terms of KL divergence between the distributions of cover and stego images. The three stages in the processing of steganalysis are analyzed, on the basis of which metric E is measured by relative performance. The common LSB based steganalysis schemes are evaluated by metric E. Experimental results show that the index E given here can measure the efficiency of steganalysis schemes effectively.
Analyzing Motion Parameters Using Unsupervised FuzzyC-PrototypesSupot Nitsuwat

Motion-based segmentation plays an important role in dynamic scene analysis of video sequence. This technique should not only cluster the feature vectors but also extract the optimum number of clusters that correspond to the moving objects. The motion features of moving objects in a video sequence have to be extracted so that segmentation can be performed based on this information. In this paper, we present a scheme for extracting moving objects. First, the dense optical ow elds are calculated to extract motion vectors. Surface tting is performed over the parametric motion model. Then, an unsupervised robust fuzzy C-Prototypes clustering technique is applied to motion-based segmentation in the parameter space. Finally, the individual moving object and background can be represented in layers. Experimental results showing the signiicance of ths proposed method are provided.
Algorithm for NO/sub 2/ vertical column retrieval from the ozone monitoring instrument

We describe the operational algorithm for the retrieval of stratospheric, tropospheric, and total column densities of nitrogen dioxide (NO/sub 2/) from earthshine radiances measured by the Ozone Monitoring Instrument (OMI), aboard the EOS-Aura satellite. The algorithm uses the DOAS method for the retrieval of slant column NO/sub 2/ densities. Air mass factors (AMFs) calculated from a stratospheric NO/sub 2/ profile are used to make initial estimates of the vertical column density. Using data collected over a 24-h period, a smooth estimate of the global stratospheric field is constructed. Where the initial vertical column densities exceed the estimated stratospheric field, we infer the presence of tropospheric NO/sub 2/, and recalculate the vertical column density (VCD) using an AMF calculated from an assumed tropospheric NO/sub 2/ profile. The parameters that control the operational algorithm were selected with the aid of a set of data assembled from stratospheric and tropospheric chemical transport models. We apply the optimized algorithm to OMI data and present global maps of NO/sub 2/ VCDs for the first time.
Airborne observations of regional variation in fluorescent aerosol across the United States

Airborne observations of fluorescent aerosol were made aboard an airship during CloudLab, a series of flights that took place in September and October of 2013 and covered a wideband of longitude across the continental U.S. between Florida and California and between 28 and 37 N latitudes. Sampling occurred from near the surface to 1000 m above the ground. A Wideband Integrated Bioaerosol Sensor (WIBS‐4) measured average concentrations of supermicron fluorescent particles aloft (1 µm to 10 µm), revealing number concentrations ranging from 2.1 ± 0.8 to 8.7 ± 2.2 × 104 particles m−3 and representing up to 24% of total supermicron particle number. We observed distinct variations in size distributions and fluorescent characteristics in different regions, and attribute these to geographically diverse bioaerosol. Fluorescent aerosol detected in the east is largely consistent with mold spores observed in a laboratory setting, while a shift to larger sizes associated with different fluorescent patterns is observed in the west. Fluorescent bioaerosol loadings in the desert west were as high as those near the Gulf of Mexico, suggesting that bioaerosol is a substantial component of supermicron aerosol both in humid and arid environments. The observations are compared to model fungal and bacterial loading predictions, and good agreement in both particle size and concentrations is observed in the east. In the west, the model underestimated observed concentrations by a factor between 2 and 4 and the prescribed particle sizes are smaller than the observed fluorescent aerosol. A classification scheme for use with WIBS data is also presented.
Oxytocin Increases the Influence of Public Service Advertisements

This paper presents a neurophysiologic model of effective public service advertisements (PSAs) and reports two experiments that test the model. In Experiment 1, we show that after watching 16 PSAs participants who received oxytocin, compared to those given a placebo, donated to 57% more causes, donated 56% more money, and reported 17% greater concern for those in the ads. In Experiment 2, we measured adrenocorticotropin hormone (ACTH) and oxytocin levels in blood before and after participants watched a PSA. As predicted by the model, donations occurred when participants had increases in both ACTH and oxytocin. Our results indicate that PSAs with social content that cause OT release will be more effective than those that do not. Our results also explain why some individuals do not respond to PSAs.
Space-Mapping Optimization With Adaptive Surrogate Model

The proper choice of mapping used in space-mapping optimization algorithms is typically problem dependent. The number of parameters of the space-mapping surrogate model must be adjusted so that the model is flexible enough to reflect the features of the fine model, but at the same time is not over flexible. Its extrapolation capability should allow the prediction of the fine model response in the neighborhood of the current iteration point. A wrong choice of space-mapping type may lead to poor performance of the space-mapping optimization algorithm. In this paper, we consider a space-mapping optimization algorithm with an adaptive surrogate model. This allows us to adjust the type of space-mapping surrogate model used in a given iteration based on the approximation/extrapolation capability of the model. The technique does not require any additional fine model evaluations
Rice SCAMP1 Defines Clathrin-Coated, trans-Golgi–Located Tubular-Vesicular Structures as an Early Endosome in Tobacco BY-2 Cells[W][OA]

We recently identified multivesicular bodies (MVBs) as prevacuolar compartments (PVCs) in the secretory and endocytic pathways to the lytic vacuole in tobacco (Nicotiana tabacum) BY-2 cells. Secretory carrier membrane proteins (SCAMPs) are post-Golgi, integral membrane proteins mediating endocytosis in animal cells. To define the endocytic pathway in plants, we cloned the rice (Oryza sativa) homolog of animal SCAMP1 and generated transgenic tobacco BY-2 cells expressing yellow fluorescent protein (YFP)–SCAMP1 or SCAMP1-YFP fusions. Confocal immunofluorescence and immunogold electron microscopy studies demonstrated that YFP-SCAMP1 fusions and native SCAMP1 localize to the plasma membrane and mobile structures in the cytoplasm of transgenic BY-2 cells. Drug treatments and confocal immunofluorescence studies demonstrated that the punctate cytosolic organelles labeled by YFP-SCAMP1 or SCAMP1 were distinct from the Golgi apparatus and PVCs. SCAMP1-labeled organelles may represent an early endosome because the internalized endocytic markers FM4-64 and AM4-64 reached these organelles before PVCs. In addition, wortmannin caused the redistribution of SCAMP1 from the early endosomes to PVCs, probably as a result of fusions between the two compartments. Immunogold electron microscopy with high-pressure frozen/freeze-substituted samples identified the SCAMP1-positive organelles as tubular-vesicular structures at the trans-Golgi with clathrin coats. These early endosomal compartments resemble the previously described partially coated reticulum and trans-Golgi network in plant cells.
Geometry of $Q$-recurrent maps

Given a critically periodic quadratic map with no secondary renormalizations, we introduce the notion of $Q$-recurrent quadratic polynomials. We show that the pieces of the principal nest of a $Q$-recurrent map $f_c$ converge in shape to the Julia set of $Q$. We use this fact to compute analytic invariants of the nest of $f_c$, to give a complete characterization of complex quadratic Fibonacci maps and to obtain a new auto-similarity result on the Mandelbrot set.
Link prediction in weighted networks

Many complex networks feature relations with weight information. Some models utilize this information while other ignore the weight information when inferring the structure. In this paper we investigate if edge-weights when modeling real networks, carry important information about the network structure. We compare five prominent models by their ability to predict links both in the presence and absence of weight information. In addition we quantify the models ability to account for the edge-weight information. We find that the complex models generally outperform simpler models when the task is to infer presence of edges, but that simpler models are better at inferring the actual weights.
