First- and second-level agenda setting in the Twittersphere: An application to the Italian political debate

ABSTRACT The rise of social network sites reopened the debate on the ability of traditional media to influence public opinion and act as an agenda setter. To answer this question, the present paper investigates first-level and second-level agenda-setting effects in the online environment by focusing on two heated Italian political debates (the reform of public funding of parties and the debate over austerity). By employing innovative and efficient statistical methods such as the lead–lag analysis and supervised sentiment analysis, we compare the attention devoted to each issue and the content spread by online news media and Twitter users. Our results show that online media keep their first-level agenda-setting power even though we find a marked difference between the slant of online news and the Twitter sentiment.
Automatic Construction of Statistical Shape Models for Protein Spot Analysis in Electrophoresis Gels

Proteomics research relies heavily on electrophoresis gels, which are complex images containing many protein ‘spots’. The identification and quantification of these spots is a bottleneck in the proteomics workflow. We describe a statistical model of protein spot appearance that is both general enough to represent unusual spots, and specific enough to introduce constraints on the interpretation of complex images. We propose a robust method of automatic model construction that is used to circumvent manual model construction which is subjective and time-consuming. We show that the statistical model of spot appearance is able to fit to image data more closely than the commonly used spot parameterisations which are based solely on Gaussian and diffusion formulations.
N′-(3-Bromo-5-chloro-2-hydroxybenzylidene)-2-methoxybenzohydrazide

The title compound, C15H12BrClN2O3, was obtained by the condensation reaction between 3-bromo-5-chloro-2-hydroxybenzaldehyde and 2-methoxybenzohydrazide. The molecule is essentially planar, with a dihedral angle between the two benzene rings of 4.7 (2)°, and displays an E configuration about the C=N double bond. The molecular conformation is stabilized by intramolecular O—H⋯N and N—H⋯O hydrogen bonds. In the crystal structure, molecules are linked into zigzag chains running parallel to the c axis by intermolecular C—H⋯O hydrogen bonds. The chains are further connected through aromatic π–π stacking interactions with centroid–centroid distances of 3.583 (4) Å.
On the Average Density and Selectivity of Nodes in Multi-Digit Tries

We introduce and study two parameters of nodes in tries with multi-digit branching. The first parameter, which we call a density of a multi-digit node, is a ratio of the number of non-empty pointers (i.e. pointers to the attached non-empty sub-tries) to the total number of pointers in this node. The second parameter, which we call a selectivity of a node, is a ratio of the number of pointers to external nodes (containing uniquely identified strings) to the total number of strings processed by this node. We show, that in a memoryless model, the average density and the average selectivity of an r-digit node over n binary strings both yield asymptotic expressions in the form Φ (r − r∗) / σ∗√log n , where, however, their central values r∗ and factors σ∗ are different if the source is asymmetric. We use our findings to explain several interesting facts in the average behaviour of multidigit tries, and complement our presentation with a number of experimental results.
The use of wireless e-mail to improve healthcare team communication.

OBJECTIVE To assess the impact of using wireless e-mail for clinical communication in an intensive care unit (ICU). DESIGN The authors implemented push wireless e-mail over a GSM cellular network in a 26-bed ICU during a 6-month study period. Daytime ICU staff (intensivists, nurses, respiratory therapists, pharmacists, clerical staff, and ICU leadership) used handheld devices (BlackBerry, Research in Motion, Waterloo, ON) without dedicated training. The authors recorded e-mail volume and used standard methods to develop a self-administered survey of ICU staff to measure wireless e-mail impact. MEASUREMENTS The survey assessed perceived impact of wireless e-mail on communication, team relationships, staff satisfaction and patient care. Answers were recorded on a 7-point Likert scale; favorable responses were categorized as Likert responses 5, 6, and 7. RESULTS Staff sent 5.2 (1.9) and received 8.9 (2.1) messages (mean [SD]) per day during 5 months of the 6-month study period; usage decreased after study completion. Most (106/125 [85%]) staff completed the questionnaire. The majority reported that wireless e-mail improved speed (92%) and reliability (92%) of communication, improved coordination of ICU team members (88%), reduced staff frustration (75%), and resulted in faster (90%) and safer (75%) patient care; Likert responses were significantly different from neutral (p < 0.001 for all). Staff infrequently (18%) reported negative effects on communication. There were no reports of radiofrequency interference with medical devices. CONCLUSIONS Interdisciplinary ICU staff perceived wireless e-mail to improve communication, team relationships, staff satisfaction, and patient care. Further research should address the impact of wireless e-mail on efficiency and timeliness of staff workflow and clinical outcomes.
Composing Context Sensitive Analysis

In this paper we present a mechanism for developing context-sensitive analyses by composing together two analyses: a subject analysis and a context analysis. The construction provides a means for building analyses of complex properties out of analyses of simpler component properties. In particular, it becomes possible to introduce different forms of context-sensitivity into an analysis. This paper also considers the practical problems of implementing such analyses. In particular, the naive method of implementing the construction leads to analyses that are impractical and infeasible. We attack this problem by proposing a generic abstraction scheme based on the duality-theory of Boolean algebras that makes this approach for building context-sensitive analyses practical
Modified putty index matrix technique with mylar strip and a new classification for selecting the type of matrix in anterior proximal/incisal composite restorations

Matrix technique described in this article combines the advantages of both flexible and rigid matrix in anterior composite restorations. Using mylar strip provide advantages, of one utilizing the mylar strip for contouring the labial aspect of restoration thereby, and overcomes the problem in adapting the teflon tape around the tooth.
A comparison of macular translocation with patch graft in neovascular age-related macular degeneration.

PURPOSE To compare the long-term outcomes of macular translocation (MT) and autologous RPE-choroid patch graft (PG) in patients with neovascular age-related macular degeneration (AMD). METHODS This is a retrospective review of the first 12 patients who underwent MT and the first 12 patients who underwent PG. Visual acuity (VA), contrast sensitivity (CS), clinical findings, and complications were recorded. Microperimetry and fundus imaging were reviewed. Outcome measures were the change in VA and CS over 3 years in each group and rates of complication. Microperimetry and fixation in three best cases from each group were described. RESULTS The two groups were matched for age and VA. Median follow-up durations were 41 (MT) and 38 (PG) months. Median VA (logMAR) was maintained in the MT group: 0.90 at baseline and 0.69 at 3 years (P=0.09) whereas in the PG group, median VA declined from 0.87 to 1.38 at 3 years (P<0.001). Both surgical modalities had high rates of detachment and macular edema. Although more extensive RPE damage occurred in PG, the graft resisted growth of recurrent choroidal neovascularization toward the fovea. Near normal VA was achievable by each technique but macular sensitivity and fixation stability were superior in the MT group. CONCLUSIONS In the present cohort, MT maintained VA for 3 years but PG did not. This outcome may be related to the differences in surgical approach, source of RPE, and choroidal perfusion. The authors recommend MT in preference to PG for treatment of patients with the second eye affected by neovascular AMD unsuitable for other treatment.
Genomic analysis of acute leukemia

Acute leukemia is the commonest childhood cancer and a major cause of morbidity from hematologic malignancies in adults. Acute lymphoblastic leukemia (ALL) is commonest in children, and acute myeloid leukemia (AML) is more frequent in adults. Apart from childhood ALL, the prognosis of acute leukemia is suboptimal, with many patients experiencing relapse, which carries a poor prognosis, or toxicities from nonspecific therapies. Recent years have witnessed great interest in the application of high‐resolution, genome wide approaches to the study of acute leukemia. These studies have identified multiple novel genetic alterations targeting critical cellular pathways that contribute to leukemogenesis, including alterations of genes regulting lymphoid development, tumor suppressors, apoptosis regulators, and oncogenes. These studies have also delineated novel genetic alterations that are associated with prognosis, and have demonstrated substantial evolution in patterns of genetic alterations from diagnosis to relapse, indicating that specific genetic changes determine resistance to therapy in ALL. Overall, fewer recurring alterations have been identified in AML. These studies have demonstrated the power of genome‐wide approaches to identify new lesions in acute leukemia, and suggest that ongoing genomic analyses, including deep resequencing and epigenetic analysis, will continue to yield novel, clinically relevant insights into the pathogenesis of this disease.
A unified architecture for crypto-processing in embedded systems

Security is an emerging concern in the design of embedded systems. Various side channel attacks must be tackled by the implementation of secure embedded system. This paper proposes a unified architecture of crypto-processor that can resist probing attacks of internal bus and memory. Private keys are maintained within the execution unit to reduce the possibility of leakage during cryptographic operations. The scalable execution structure supports different key lengths and achieves high performance. The main execution unit of the proposed architecture has been implemented based on Avanti 0.35 micron library, maximum 64.4MHz frequency is reported with the utilization of 325 thousand sates.
Dual roles of plcA in Listeria monocytogenes pathogenesis

The plcA gene of Listeria monocytogenes encodes a secreted phosphatidylinositol‐speciftc phospholi‐pase C (PI‐PLC). Recent studies have established that transposon mutations within plcA result in avirulence for mice and pleiotropic effects when examined in tissue‐culture models of infection. Genetic analysis reveals that many of the effects of the transposon insertions are due to loss of readthrough transcription from plcA into the downstream gene prfA, which encodes an essential transcription factor of numerous L. monocytogenes virulence genes. Construction of an in‐frame deletion within plcA had no effect on expression of prfA thus allowing direct assignment of a role of the PI‐PLC in pathogenesis. PI‐PLC was shown to play a significant role in mediating escape of L. monocytogenes from phagosomes of primary murine macrophages. Interestingly, this defect manifested itself in vivo in the liver but not in the spleen of infected mice.
Soft biometric verification by integrating static and dynamic features based on fuzzy inference

This paper proposes a simple multimodal soft biometic verification method based on fuzzy inference. This study is a part of the challenge to develop an novel natural verification technology that a user doesn't need to hold his/her biometric features to an authentication device. We employ both of static and dynamic features obtained from an appearance of a person in gait. As the result of verification experiment, we show that our developed method works successfully in spite of simple approach and an easy-to-use device.
Soundless Horn And Remote Patroller

Due to the fast growing vehicle population in the recent years has resulted in considerable increase in the traffic on roads, causing alarming noise pollution and also making the task of vehicle monitoring cumbersome for the civil force. This paper proposes an idea to design an on board equipment SHARP which implements soundless horn, a mechanism for vehicles to reduce the traffic noise and a remote patroller to aid the civil force in monitoring the vehicles remotely with enhanced hit ratio of black listed vehicles. The proposed idea, integrates the technologies of image processing and inter vehicular communication for its implementation. The designed on board equipment is targeted for four wheelers and a typical SHARP system is made up of --a camera, processor, DSRC transceiver, GPS device and an LCD display.
International Classification of Childhood Cancer, third edition

The third edition of the International Classification of Diseases for Oncology (ICD‐O‐3), which was published in 2000, introduced major changes in coding and classification of neoplasms, notably for leukemias and lymphomas, which are important groups of cancer types that occur in childhood. This necessitated a third revision of the 1996 International Classification of Childhood Cancer (ICCC‐3).
Indoor Elliptical Localization Based on Asynchronous UWB Range Measurement

An asynchronous position measurement system is proposed for indoor localization in this paper. The demonstrated system consists of a UWB transmitter and several energy detection receivers whose positions are known. The position measurement process starts with the locator emitting a UWB pulse. Upon arrival, the pulse is amplified and retransmitted by the target to be located. Signals from both the locator and the target are captured by the receivers. No synchronization mechanism is implemented. Instead, the proposed system measures the differential TOA between the direct coupling signal of the locator and the target signal. Together with the knowledge of the locator transmitter and receiver positions, the absolute range that the pulse travels can be calculated. The sum of transmitter-target range and target-receiver range defines an ellipse and the target resides on the intersections of several such ellipses. It is shown via the Cramer-Rao lower bound that the absolute-range-based elliptical localization is potentially more accurate than the relative-range-based hyperbolic localization. Our proposed system is able to achieve positioning error bound comparable to synchronous absolute-range-based localization systems while eliminating the cost of synchronization.
The Pulmonary Circulation and Interstitial Space

Organization and Development of the Embryo is based on a series of Silliman Lectures at Yale University given by Ross G. Harrison in 1949 under the same title. Professor Harrison was unable to prepare these lectures for publication because of illness, but his assistant, Miss Sally Wilens, has assembled in this volume the notes and papers of Professor Harrison on which the content of the lectures was based. The five papers reprinted here concern cellular differentiation, tissue culture, development of the nervous system, symmetry in development, and heteroplastic grafting. A synopsis of the lectures and a summary by Professor Harrison aids in relating the papers to the lectures. In addition, new material is included in the form of excerpts from the Silliman Lecture notes interpolated in the papers by Miss Wilens, figures taken from slides used to illustrate the lectures, and a previously unpublished account of the embryonic development of the spotted salamander, Amblystoma punctatum. The papers themselves are primarily of historical interest and its does not seem significant how closely the volume conforms to the original organization of the lectures. Of greater importance is that this collection of writings records the general thoughts and concepts of Professor Harrison on embryonic organization and development. With the inclusion of a preface on Professor Harrison's life and a complete bibliography of his published papers, the volume emerges as a fitting tribute to the entire life and work of Ross Harrison. Since the field of developmental biology owes much to the contributions of Professor Harrison, this volume will be of interest and value to all those working in this area. THOMAS L. LENTZ
A New Method for Measuring Similarity between Intuitionistic Fuzzy Sets Based on Normal Distribution Functions

This paper puts forward a new kind of similarity measure between intuitionistic fuzzy sets (IFSs) based on normal distribution functions. At first, we propose a method to express an intuitionistic fuzzy set by a series of normal distribution functions. Then, we use these normal distribution functions to calculate the degree of similarity between IFSs. The properties of the proposed similarity measure are proved and several numerical examples are taken to validate it. Compared with the existing methods, the proposed similarity measure is more reasonable and more suitable for any special situation. Moreover, by comparing the proposed similarity measure with the existing measures, our method shows that it is much more reliable than the existing measures to linguistic variables. Though having a little difficulty for calculation, the similarity measure presents a brand- new method to deal with fuzzy information.
Timber Sale Auctions with Random Reserve Prices

This paper analyzes first-price sealed-bid auctions of standing timber organized by the French forest service, Office National des Forts (ONF). A feature of these auctions is that they are held with random reserve prices. We consider an auction model with a random reserve price within the independent-private-value paradigm. After establishing the identification of the model, we estimate the underlying bidders' private-value distribution by using a simple two-step nonparametric procedure. This procedure allows the computation of the winners' informational rents as well as the optimal reserve price. We then simulate a first-price sealed-bid auction with the optimal announced reserve price. Empirical results show that the optimal reserve price allows the ONF to extract more of bidders' willingnesses to pay. Moreover, our results show that, though sales do not vary much, profits for the ONF would significantly increase and less timber would be sold.
Step size analysis in discrete-time dynamic average consensus

This paper deals with the problem of reaching the average consensus of a set of time-varying reference signals in a distributed manner. We analyze the approach initially presented in [1], giving an alternative proof of convergence which leads to larger, more realistic bounds on the step sizes that guarantee a steady-state error upper-bounded by a given constant. The interest of the new results appear when the algorithm is used in real networks, where there are constraints in the communication rate between the nodes. We derive the bounds for the cases of fixed and time-varying communication topologies, as well as for different orders of the algorithm. We demonstrate that our bounds always allow substantially bigger step sizes than those in [1], independently of the number of nodes or the topology. Moreover, for a fixed step size and steady-state error, we show how there is a corresponding algorithm that can guarantee that the error is no larger than the desired one, using that step size. Finally, simulation results corroborate the theoretical findings of the paper.
Comparison of parallel image scanning methods for achieving better throughput

Higher throughput is always desired in real time image processing applications. There are many ways to achieve higher throughput. However, if we have additional resources and memory bandwidth available, parallelism can be applied to achieve it. In this work, we have presented two image scanning methods that carry out parallelism to double the throughput of any architecture. Partitioned image scanning method divides the input image into two or more sub-images and then applies the desired filter function on each sub-image in parallel. Adjacent row scanning method provides the input to each filter alternatively, one accessing odd rows and the other even rows of the input image. From the results, it is evident that the resources utilized by partitioned image scanning method are more than that of adjacent row scanning method. The results show that adjacent row scanning method require approximately 20% lesser resources than that required by partitioned image scanning method.
Comparing resting skin sympathetic nerve activity between groups: caution needed.

TO THE EDITOR: We read with interest the recently published work of Park et al. (10) examining differential regional control of sympathetic nerve activity in end-stage renal disease (ESRD). These investigators compared integrated multiunit recordings of muscle sympathetic nerve activity (MSNA) and skin sympathetic nerve activity (SSNA) at rest between patients with ESRD and healthy age- and gender-matched control subjects, using the technique of microneurography. Similar to previous reports, the ESRD patients demonstrated greater resting MSNA compared with controls. However, SSNA was similar between the two groups, leading the authors to conclude that “. although sympathetic activity directed to muscle is significantly elevated, activity directed to skin is not elevated in ESRD. ” Although we commend the authors for addressing this important issue, there are major limitations in comparing basal SSNA between groups that should be considered, despite the work of others who have performed similar analyses (5, 8, 11).
Automatic Extraction of Biological Information from Scientific Text: Protein-Protein Interactions

We describe the basic design of a system for automatic detection of protein-protein interactions extracted from scientific abstracts. By restricting the problem domain and imposing a number of strong assumptions which include pre-specified protein names and a limited set of verbs that represent actions, we show that it is possible to perform accurate information extraction. The performance of the system is evaluated with different cases of real-world interaction networks, including the Drosophila cell cycle control. The results obtained computationally are in good agreement with current biological knowledge and demonstrate the feasibility of developing a fully automated system able to describe networks of protein interactions with sufficient accuracy.
