Recognizing 3-D Objects Using 2-D Images

We discuss a strategy for visual recognition by forming groups of salient image features, and then using these groups to index into a data base to find all of the matching groups of model features. We discuss the most space efficient possible method of representing 3-D models for indexing from 2-D data, and show how to account for sensing error when indexing. We also present a convex grouping method that is robust and efficient, both theoretically and in practice. Finally, we combine these modules into a complete recognition system, and test its performance on many real images.

Activities of Combinations of Antistaphylococcal Antibiotics with Fusidic Acid against Staphylococcal Biofilms in In Vitro Static and Dynamic Models

ABSTRACT Staphylococcal biofilms are a major cause of therapeutic failure, especially when caused by multiresistant strains. Oral fusidic acid is currently being redeveloped in the United States for skin, skin structure, and orthopedic infections, in which biofilms play a major role. The aim of this study was to examine the activity of fusidic acid alone or combined with other antistaphylococcal drugs against biofilms made by a reference strain and five clinical isolates of Staphylococcus aureus or Staphylococcus epidermidis in in vitro static and dynamic models (microtiter plates and a CDC reactor) exposed to clinically relevant concentrations. In microtiter plates, antibiotics alone were poorly active, with marked differences among strains. At concentrations mimicking the free-drug human maximum concentration of drug in serum (Cmax), the combination of fusidic acid with linezolid, daptomycin, or vancomycin resulted in increased activity against 4 to 5 strains, while the combination with doxycycline, rifampin, or moxifloxacin increased activity against 1 to 3 strains only. In the CDC reactor, biofilms were grown under constant flow and antibiotic concentrations decreased over time according to human elimination rates. A bactericidal effect was obtained when fusidic acid was combined with daptomycin or linezolid, but not with vancomycin. The higher tolerance of biofilms to antibiotics in the CDC reactor is probably attributable to the more complex architecture they adopt when growing under constant flow. Because biofilms grown in the CDC reactor are considered more similar to those developing in vivo, the data support further testing of combinations of fusidic acid with daptomycin or linezolid in models pertinent to chronic skin, skin structure, or orthopedic infections.
Empirical study of automatic dataset labelling

Correctly labelled datasets are commonly required. Three particular scenarios are highlighted, which showcase this need. One of these scenarios is when using supervised Intrusion Detection Systems (TDSs). These systems need labelled datasets for their training process. Also, the real nature of analysed datasets must be known when evaluating the efficiency of IDSs detecting intrusions. The third scenario is the use of feature selection that works only if the processed datasets are labelled. In normal conditions, collecting labelled datasets from real communication networks is impossible. In a previous work we developed a novel approach to automatically generate labelled network traffic datasets using an unsupervised anomaly based IDS. The approach was empirically proven to be an efficient unsupervised labelling approach. It was evaluated using a single dataset. This paper extends our previous work by using a greater number of datasets, gathered from a real IEEE 802.11 network testbed. The datasets are comprised of different wireless-specific attacks. This paper also proposes a new and more precise method to calculate the boundary threshold, used in the labelling process.
How Different Video Club Designs Support Teachers in “Learning to Notice”

Abstract Video is currently a key element of numerous professional development programs, yet relatively little is known about how video fosters changes in teachers’ thinking. This study examines how a particular type of videobased professional development, namely video clubs, supports teacher development. Video clubs are professional development environments in which groups of teachers come together to view and discuss videos of one another’s teaching. In this paper, we study how two different video club designs support teachers in “learning to notice” classroom interactions in new ways. Data for this study include a pre- and post-interview conducted with each participating teacher from the two video clubs. Analysis reveals that, for one group, the scope of their comments became focused on a particular issue, interpreting the mathematical ideas expressed by students in the video excerpts. In contrast, the second group developed a range of perspectives for discussing the video segments. We argue that the different designs of the video clubs influenced the ways in which the two groups of teachers “learned to notice. ”
Does Anyone Listen When Politicians Talk? The Effect of Political Commentaries on Policy Rate Decisions and Expectations

This paper investigates the effects of political commentaries on policy rate decisions and policy expectations in the United States and the euro area. The results suggest that political commentaries do influence policy rate expectations in both regions, even after controlling for macroeconomic releases and immediate interest rate expectations. The findings regarding the policy reaction functions reveal that market expectations are mostly rational. There is no evidence that the Federal Reserve responds to political commentaries that suggest rate hikes or easings. Meanwhile, the European Central Bank seems to have steered its policy in line with political commentaries that suggested further easings during the pre-crisis period, consistent with market expectations.
Magnetically Aligned Velocity Anisotropy in the Taurus Molecular Cloud

Velocity anisotropy induced by MHD turbulence is investigated using computational simulations and molecular line observations of the Taurus molecular cloud. A new analysis method is presented to evaluate the degree and angle of velocity anisotropy using spectroscopic imaging data of interstellar clouds. The efficacy of this method is demonstrated on model observations derived from three-dimensional velocity and density fields from the set of numerical MHD simulations that span a range of magnetic field strengths. The analysis is applied to 12CO J = 1–0 imaging of a subfield within the Taurus molecular cloud. Velocity anisotropy is identified that is aligned within ~10° of the mean local magnetic field direction derived from optical polarization measurements. Estimated values of the field strength based on velocity anisotropy are consistent with results from other methods. When combined with new column density measurements for Taurus, our magnetic field strength estimate indicates that the envelope of the cloud is magnetically subcritical. These observations favor strong MHD turbulence within the low-density, subcritical, molecular gas substrate of the Taurus cloud.
Self-Controlled Learning: The Importance of Protecting Perceptions of Competence

Recent studies examining the role of self-controlled feedback have shown that learners ask for feedback after what they believe was a “good” rather than “poor” trial. Also, trials on which participants request feedback are often more accurate than those without feedback. The present study examined whether manipulating participants’ perception of “good” performance would have differential effects on learning. All participants practiced a coincident-anticipation timing task with a self-controlled feedback schedule during practice. Specifically, they were able to ask for feedback after 3 trials in each of three 10-trial practice blocks. While one group (Self-30) was told that an error of 30 ms or less would be considered good performance, another group (Self-4) was informed that an error of 4 ms or less would be considered a good trial. A third, self-control group (Self) did not receive any information about what constituted good performance. The results showed that participants of all groups asked for feedback primarily after relatively good trials. At the end of practice, both the Self-30 and Self groups demonstrated greater perceived competence and self-efficacy than the Self-4 group. The Self-30 and Self groups also performed with greater accuracy and less variability in retention and transfer (non-dominant hand) 1 day later. The present findings indicated that the typical learning benefits of self-controlled practice can be thwarted by depriving learners of the opportunity of experiencing competence through good performance. They add to the accumulating evidence of motivational influences on motor learning.

On successive refinement for the Wyner-Ziv problem

Achievable rates are characterized for successive refinement (SR) in the Wyner-Ziv scenario, namely, in the presence of correlated side information (SI) at the receivers. In this setting, the encoder is assumed to operate in two stages, where the first corresponds to relatively low rate and high distortion, and the second, comprising a refinement code on top of the first code, is aimed at reproduction at reduced distortion. Both decoders (for low rate/high distortion and for high rate/low distortion) are equipped with SI streams, correlated to the source, but unavailable to the encoder. Furthermore, it is assumed that the decoder that receives the higher rate bitstream, i.e., the additional refinement bits, accesses also SI of "better quality" than that of the lower resolution decoder. By "better quality," we mean that the source and the SI are modeled together as a stochastically degraded joint source, where the encoded symbols, the SI at the refinement stage, and the SI at the initial (coarse) stage, form a Markov chain in this order. For a memoryless joint process (that includes the source to be encoded and its instantaneously correlated SI streams), necessary and sufficient conditions are furnished, in terms of single-letter formulas, for the achievability of a pair of rates, corresponding to two given distortion levels. Special attention is devoted to the degenerate, but important, case where the two SI streams, at the two decoders, are identical. For this case, conditions are provided for successive refinability in the sense of the existence of codes that asymptotically achieve the Wyner-Ziv rate-distortion function, simultaneously at both distortion levels. In this context, the doubly symmetric binary source (with the Hamming distortion measure) and the jointly Gaussian source (with the squared error distortion measure) are successively refinable in the Wyner-Ziv setting. It is demonstrated that a source that is not successively refinable in the ordinary sense (i.e., without SI) may become successively refinable in the presence of SI at the decoders.
Further Development of Synchronous Array Method for Ad Hoc Wireless Networks

A further development of the synchronous array method (SAM) as a medium access control scheme for large-scale ad hoc wireless networks is presented. Under SAM, all transmissions of data packets between adjacent nodes are synchronized on a frame-by-frame basis, and the spacing between concurrent cochannel transmissions of data packets is properly controlled. An opportunistic SAM (O-SAM) is presented which allows concurrent cochannel transmissions to be locally adaptive to channel gain variations. A distributed SAM (D-SAM) is discussed that schedules all concurrent cochannel transmissions in a distributed fashion. For networks of low mobility, the control overhead required by SAM can be made much smaller than the payload. By analysis and simulation, the intranetwork throughput of O-SAM and D-SAM is evaluated. The effects of traffic load and multiple antennas on the intranetwork throughput are studied. The throughput of ALOHA is also analyzed and compared with that of O-SAM and D-SAM. By a distance-weighted throughput, a comparison of long distance transmission versus short distance transmission is also presented. The study of D-SAM reveals an important insight into the MSH-DSCH protocol adopted in IEEE 802.16 standards.
A Subcategorization Acquisition System for French Verbs

This paper presents a system capable of automatically acquiring subcategorization frames (SCFs) for French verbs from the analysis of large corpora. We applied the system to a large newspaper corpus (consisting of 10 years of the French newspaper 'Le Monde') and acquired subcategorization information for 3267 verbs. The system learned 286 SCF types for these verbs. From the analysis of 25 representative verbs, we obtained 0.82 precision, 0.59 recall and 0.69 F-measure. These results are comparable with those reported in recent related work.
Eyes Wide Shopped: Shopping Situations Trigger Arousal in Impulsive Buyers

The present study proposes arousal as an important mechanism driving buying impulsiveness. We examined the effect of buying impulsiveness on arousal in non-shopping and shopping contexts. In an eye-tracking experiment, we measured pupil dilation while participants viewed and rated pictures of shopping scenes and non-shopping scenes. The results demonstrated that buying impulsiveness is closely associated with arousal as response to viewing pictures of shopping scenes. This pertained for hedonic shopping situations as well as for utilitarian shopping situations. Importantly, the effect did not emerge for non-shopping scenes. Furthermore, we demonstrated that arousal of impulsive buyers is independent from cognitive evaluation of scenes in the pictures.
Possible active transport mechanism in pharmacokinetics of flunixin-meglumin in rabbits.

The plasma and urine kinetics of flunixin-meglumin (FNX, 2 mg/kg, i.v.) in rabbits were examined. Unusual pharmacokinetic profiles were obtained, including high binding percentage with plasma protein (> 99%), a short elimination half-life (< 4 hr) and a relatively large Vd-area (0.5 L/kg). These profiles indicate that some active transport mechanisms are involved in FNX disposition. The recovery of FNX from urine was approximately 9 % of the dose within 24 hr following the injection. The estimated renal clearance of the unbound drug nearly corresponded to the renal blood flow rates, indicating that active tubular secretion in the renal re-absorptive tract may be involved in the disposition. The effect of a concomitant administration of pravastatin (PV) on FNX disposition was also examined. PV is a representative substrate of a transporter in human liver cells (OATP-2). After the PV administrations, the Vd-area of FNX and total body clearance markedly decreased, indicating that FNX is actively taken up and metabolized in liver cells by an OATP-2 like transporter. In conclusion, there are at least 2 active transport pathways for FNX pharmacokinetics in rabbits, one is renal tubular secretion and the other is in the sinusoidal section of the liver.
Pregnancy outcomes in Chinese urban women at a very advanced maternal age.

AIM To compare the maternal-fetal outcomes in Chinese urban women at the maternal age of 40 years with those aged between 35 and 39 years. MATERIALS AND METHODS In this retrospective study, women in a single-center that delivered from January 1 to December 31, 2013, were included. The authors divided the subjects into two groups according to the age, and evaluated the obstetric history, delivery mode, incidence of obstetric diseases, and neonatal outcomes of each group. RESULTS They enrolled 1,965 pregnant women in total. The women between 35 to 39 years of age reached 1,727 (87.9%), and the remaining 238 (12.1%) were women ≥ 40-years-old. The incidence rates of in vitro fertilization (IVF,p < 0.01), gestational diabetes mellitus (GDM) (p < 0.05), and hypertension (p < 0.05) for the elder group were higher than the younger group. Furthermore, women ≥ 40-years-old were associated with a higher rate of cesarean section (84.0% vs. 67.6%,p < 0.001) compared with the younger group, varying significantly on intrauterine infection (1.5% vs. 0.5%,p < 0.05), IVF (6.5% vs. 3.2%,p < 0.01), and maternal request (41.0% vs. 30.6%,p < 0.001). No significant differences in neonatal outcomes were found and no neonatal deaths were recorded for the two groups. CONCLUSIONS These results showed an increase risk of pregnancy complications for the women giving birth at ≥ 40 years of age, yet most of them still carried a favorable pregnancy and neonatal outcome, similar to the younger women.
Hemodynamic Changes Caused by Flow Diverters in Rabbit Aneurysm Models: Comparison of Virtual and Realistic FD Deployments Based on Micro-CT Reconstruction

Adjusting hemodynamics via flow diverter (FD) implantation is emerging as a novel method of treating cerebral aneurysms. However, most previous FD-related hemodynamic studies were based on virtual FD deployment, which may produce different hemodynamic outcomes than realistic (in vivo) FD deployment. We compared hemodynamics between virtual FD and realistic FD deployments in rabbit aneurysm models using computational fluid dynamics (CFD) simulations. FDs were implanted for aneurysms in 14 rabbits. Vascular models based on rabbit-specific angiograms were reconstructed for CFD studies. Real FD configurations were reconstructed based on micro-CT scans after sacrifice, while virtual FD configurations were constructed with SolidWorks software. Hemodynamic parameters before and after FD deployment were analyzed. According to the metal coverage (MC) of implanted FDs calculated based on micro-CT reconstruction, 14 rabbits were divided into two groups (A, MC >35%; B, MC <35%). Normalized mean wall shear stress (WSS), relative residence time (RRT), inflow velocity, and inflow volume in Group A were significantly different (P<0.05) from virtual FD deployment, but pressure was not (P>0.05). The normalized mean WSS in Group A after realistic FD implantation was significantly lower than that of Group B. All parameters in Group B exhibited no significant difference between realistic and virtual FDs. This study confirmed MC-correlated differences in hemodynamic parameters between realistic and virtual FD deployment.
Anomalies Correlation for Risk-Aware Access Control Enhancement

In the context of database management systems (DBMS), the integrity of access control policies (ACP) is a constantly neglected aspect. However, throughout its evolution, ACP is not valid and free from irregularities due to users and administrators actions, intentionally or not. So, considering regular ACP updating activities, we pay a particular attention on anomalies in ACP expression. Taking into account the correlation that exists between two or more of such anomalies, we present the “correlated threats management system” (CORMSYS). This system must detect and analyze the correlation between anomalies since we believe that handling correlations between anomalies can reveal sophisticated intrusion scenarios in DBMS. The presented system also produces the necessary input for new risk management approach that will consider and overcome the effects induced by the correlation between anomalies found in the ACP expression. CORMSYS is composed of four main parts: (i) the Correlation Definition and Analysis subsystem; (ii) the Users Tracking subsystem; (iii) the Intrusion Scenario Identification subsystem and (iv) the Illegal Behavior
Azathioprine‐induced alopecia and leukopenia associated with NUDT15 polymorphisms

Azathioprine (AZA), a widely used immunosuppressant, can induce cytotoxic effects including myelosuppression and alopecia.1 Recent studies revealed that polymorphisms of NUDT15 are associated with thiopurine-induced alopecia and leukopenia.2-5 The frequency of NUDT15 polymorphisms in East and South Asians is high (22.6% and 13.6%, respectively). 5 Thus, adverse event management during AZA treatment is essential for Asian populations with these polymorphisms.

Big database stores a review on various big data datastores

In this age where there is a massive explosion in the data in our surroundings, the traditional way of actually storing and processing the data is no longer feasible. Moreover, the unstructured data that is present cannot be processed by the conventional ways. With the emergence of this data explosion also known as Big Data, a lot of importance has given to actually process and more importantly analyze the data to get the best results being in terms of decision making or predicting the future evens based on the past data at hand. The traditional SQLs have become impractical to process the latest data inflow as it lacks the structure, elasticity requirements and the high scalability. NoSQL or what can be known as Not Only SQL actually help find by a way out of the traditional approach and help process the unstructured data. For Big Data to function at its best, it needs the help of specialized databases that help in storing and processing data when needed. There are 4 main categories of the Datastores used in Big Data namely Key-Value Pair Datastore, Column Oriented Datastore, Document Oriented Datastore and Graph Datastores.
