FlowNAC: Flow-based Network Access Control

This paper presents FlowNAC, a Flow-based Network Access Control solution that allows to grant users the rights to access the network depending on the target service requested. Each service, defined univocally as a set of flows, can be independently requested and multiple services can be authorized simultaneously. Building this proposal over SDN principles has several benefits: SDN adds the appropriate granularity (fine-or coarse-grained) depending on the target scenario and flexibility to dynamically identify the services at data plane as a set of flows to enforce the adequate policy. FlowNAC uses a modified version of IEEE 802.1X (novel EAPoL-in-EAPoL encapsulation) to authenticate the users (without the need of a captive portal) and service level access control based on proactive deployment of flows (instead of reactive). Explicit service request avoids misidentifying the target service, as it could happen by analyzing the traffic (e.g. private services). The proposal is evaluated in a challenging scenario (concurrent authentication and authorization processes) with promising results.
Indoor radon concentration measurements at the locations of the first nuclear power plants of Vietnam

The Vietnamese government has decided to build the first two nuclear power plants in Ninh Thuan province. This study reports the indoor radon (Rn) survey of the area in the vicinity of the nuclear plants to be built in this province. The survey was conducted during the years 2010-2011 in order to establish the radioactive background database of the province before the nuclear power plant is built and put into operation. Fifty nine locations (representing the 59 most populated of the 64 communes in the province) were investigated. Indoor Rn concentration was measured using Solid State Nuclear Track Detector (SSNTD) LR-115 type II strippable with 3 months exposure for the dose assessment of the future population. Rn concentration values gained during the survey were rather low in general compared to the data of other international surveys. The average was 10±5 Bq/m (min. 4 Bq/m; max. 27 Bq/m). From the point of view of dosimetry even the highest estimated effective dose originating from the Rn concentration is negligible. After the completion of the power plants, however, the previous background data have crucial importance in order to assess the concentrations due to the power plants and to provide credible information to the public.
Effect of a Multi-Dimensional Intervention Programme on the Motivation of Physical Education Students

This research study purports to verify the effect produced on the motivation of physical education students of a multi-dimensional programme in dance teaching sessions. This programme incorporates the application of teaching skills directed towards supporting the needs of autonomy, competence and relatedness. A quasi-experimental design was carried out with two natural groups of 4th year Secondary Education students - control and experimental -, delivering 12 dance teaching sessions. A prior training programme was carried out with the teacher in the experimental group to support these needs. An initial and final measurement was taken in both groups and the results revealed that the students from the experimental group showed an increase of the perception of autonomy and, in general, of the level of self-determination towards the curricular content of corporal expression focused on dance in physical education. To this end, we highlight the programme's usefulness in increasing the students' motivation towards this content, which is so complicated for teachers of this area to develop.
Technical note: Anticorrosive behaviour of octadecylamine for protection of boiler surfaces

Abstract The anticorrosive behaviour of octadecylamine (ODA) films has been investigated via weight loss and electrochemical methods. Tests were conducted on specimens of carbon steel, brass, and austenitic stainless steel in the presence and absence of amine films. Inhibitor efficiency values in excess of 94·5% were obtained in this series of experiments. These results have been applied for the protection of boiler surfaces when out of service. For surfaces that were coated with ODA before lay up began, the optimum concentration of ODA for protection while out of surface was found to be 0·2 ppm.
A study for the effect of widened auditory filter of hearing impaired listener

The reduced frequency selectivity is a typical phenomenon of sensorineural hearing loss. In this paper, we made modeling of reduced frequency selectivity for hearing impaired listener. The model of reduced frequency selectivity was generated with bandwidth control algorithm based on ERB(equivalent rectangular bandwidth) of auditory filter. In other to examine the effectiveness of model, we compared PESQ(perceptual evaluation of speech quality) score and LLR(log likelihood ratio) score with 36 Korean worlds of two syllables. To verify the effect on noise condition, we mixed white and babble noise with 0dB and -3dB SNR to speech words. As the result, PESQ score is lower as extending bandwidth of filter however LLR score is almost same. It means that non-linearity and widen auditory filter characteristics caused by reduced frequency selectivity could be reflected in bandwidth control algorithm.
Viral E6/E7 oncogene and cellular hexokinase 2 expression in HPV-positive cancer cell lines

Oncogenic types of human papillomaviruses (HPVs) are major human carcinogens. Cancer cells typically exhibit metabolic alterations which support their malignant growth. These include an enhanced rate of aerobic glycolysis (‘Warburg effect’) which in cancer cells is often linked to an increased expression of the rate-limiting glycolytic enzyme Hexokinase 2 (HK2). Intriguingly, recent studies indicate that the HPV E6/E7 oncogenes cause the metabolic reprogramming in HPV-positive cancer cells by directly upregulating HK2 expression. Notably, however, these results were obtained upon ectopic overexpression of E6/E7. Here, we investigated whether HK2 levels are affected by the endogenous E6/E7 amounts present in HPV-positive cancer cell lines. RNA interference analyses reveal that the sustained E6/E7 expression is critical to maintain HK2 expression levels in HeLa cells. Mechanistically, this effect is linked to the E6/E7-dependent upregulation of HK2-stimulatory MYC expression and the E6/E7-induced downregulation of the HK2-inhibitory micro(mi)RNA miR-143-3p. Importantly, however, a stimulatory effect of E6/E7 on HK2 expression was observed only in HeLa among a panel of 8 different HPV-positive cervical and head and neck cancer cell lines. Thus, whereas these results support the notion that E6/E7 can increase HK2 expression, they argue against the concept that the viral oncogenes, at endogenous expression levels, commonly induce the metabolic switch of HPV-positive cancer cells towards aerobic glycolysis by directly or indirectly stimulating HK2 expression.
A Tutorial Review of Functional Connectivity Analysis Methods and Their Interpretational Pitfalls

Oscillatory neuronal activity may provide a mechanism for dynamic network coordination. Rhythmic neuronal interactions can be quantified using multiple metrics, each with their own advantages and disadvantages. This tutorial will review and summarize current analysis methods used in the field of invasive and non-invasive electrophysiology to study the dynamic connections between neuronal populations. First, we review metrics for functional connectivity, including coherence, phase synchronization, phase-slope index, and Granger causality, with the specific aim to provide an intuition for how these metrics work, as well as their quantitative definition. Next, we highlight a number of interpretational caveats and common pitfalls that can arise when performing functional connectivity analysis, including the common reference problem, the signal to noise ratio problem, the volume conduction problem, the common input problem, and the sample size bias problem. These pitfalls will be illustrated by presenting a set of MATLAB-scripts, which can be executed by the reader to simulate each of these potential problems. We discuss how these issues can be addressed using current methods.
Energy-momentum of a regular MMaS-class black hole

We compute the energy and momentum of a regular black hole of type defined by Mars, Martin-Prats, and Senovilla by using the Einstein and Papapetrou definitions for energy–momentum density. Some other definitions of energy–momentum density are shown to give mutually contradictory and less reasonable results. In addition, the resuts support the Cooperstock hypothesis.
Examination of Methicillin-Resistant and Methicillin-Susceptible Staphylococcus aureus Mutants with Low-Level Fluoroquinolone Resistance

ABSTRACT For Staphylococcus aureus, stepwise mutations result in high-level quinolone resistance. Methicillin-resistant and -susceptible quinolone-resistant, first-step mutants generated in vitro were obtained and found to be no different than those recovered from murine abscesses. Approximately 10% of all first-step mutants were resistant to ethidium bromide, and selected strains had mutations that mapped toflqB. NorA-mediated resistance among first-step mutants may be more prevalent than previously reported.
Spectrum of orbital and ocular adnexal lesions: An analysis of 389 cases diagnosed by fine needle aspiration cytology

The aim of the present study was to evaluate the scope and the limitations of fine needle aspiration cytology (FNAC) in orbital and ocular adnexal lesions. This study was a retrospective audit of 389 cases of orbital and ocular adnexal lesions subjected to FNAC over a period of 12 years (1998–2009). The cyto‐smears were reviewed and the lesions were categorized under different diagnostic categories in adult and pediatric population. Three hundred and one adult patients (age ≥15 years) and 88 pediatric patients (age ≤14 years) constituted the study group. In the adult population, there were 23.3% cases of infectious and lymphoproliferative lesions and 12.6% of benign cysts. In the pediatric population, 18.2% cases had infectious and lymphoproliferative lesions and 8% had benign cysts. Various benign tumors (9.6% in adults) included pleomorphic adenoma, meningioma, and schwannoma. Benign vascular tumors predominated in the pediatric population. A majority of malignant tumors in adults were lymphoreticular malignancies (12.6%); non‐Hodgkin's lymphoma being the most common followed by malignant epithelial tumors (10.3%). Nearly 3.6% cases of soft tissue/bone sarcomas and 6.3% of metastatic tumors were seen in adult population. However, most of the orbital tumors in the pediatric population were malignant small blue round cell tumors (33%). FNAC is a cost‐effective technique with good diagnostic value in the assessment of ophthalmic lesions, especially when sampling and interpretation are performed by experienced personnel in the light of clinico‐radiological information.

Autonomous acquisition of pushing actions to support object grasping with a humanoid robot

There are many situations in which an object that needs to be grasped is not graspable, but could be grasped if it was situated at a different location. By applying nonprehensile manipulation actions such as poking, the object can be moved to a new location without first being grasped. We consider these issues in the context of an artificial cognitive system. The goal of the paper is twofold; firstly, we study how the robot can acquire nonprehensile manipulation knowledge by observing the outcomes of exploratory movements on objects. We propose a learning process that enables the robot to acquire a general pushing rule describing the relationship between the direction of poke and the observed object motion for a class of objects. In this way the robot acquires new action knowledge without having any specialized prior model about the action. Secondly, we investigate how the acquired action knowledge can be used to realize grasping in complex situations where the robot could not grasp the object without moving it to a new location. Here the learned poking behavior serves as a support action for robot grasping. The proposed approach has been implemented and tested on a humanoid robot Armar III.
A Cook's Tour of the Finitary Non-Well-Founded Sets

We give multiple descriptions of a topological universe of finitary sets, which can be seen as a natural limit completion of the hereditarily finite sets. This universe is characterized as a metric completion of the hereditarily finite sets; as a Stone space arising as the solution of a functorial fixed-point equation involving the Vietoris construction; as the Stone dual of the free modal algebra; and as the subspace of maximal elements of a domain equation involving the Plotkin (or convex) powerdomain. These results illustrate the methods developed in the author's 'Domain theory in logical form', and related literature, and have been taken up in recent work on topological coalgebras. The set-theoretic universe of finitary sets also supports an interesting form of set theory. It contains non-well founded sets and a universal set; and is closed under positive versions of the usual axioms of set theory.
[5-HT1B serotonin receptors and antidepressant effects of selective serotonin reuptake inhibitors ].

We used knockout mice and receptor antagonist strategies to investigate the contribution of the serotonin (5-hydroxytryptamine, 5-HT) 5-HT1B receptor subtype in mediating the effects of selective serotonin reuptake inhibitors (SSRIs). Using in vivo intracerebral microdialysis in awake mice, we show that a single systemic administration of paroxetine (1 or 5 mg/kg, i.p.) increased extracellular serotonin levels [5-HT]ext in the ventral hippocampus and frontal cortex of wild-type and mutant mice. However, in the ventral hippocampus, paroxetine at the two doses studied induced a larger increase in [5-HT]ext in knockout than in wild-type mice. In the frontal cortex, the effect of paroxetine was larger in mutants than in wild-type mice at the 1 mg/kg dose but not at 5 mg/kg. In addition, either the absence of the 5-HT1B receptor or its blockade with the mixed 5-HT1B/1D receptor antagonist, GR 127935, potentiates the effect of a single administration of paroxetine on [5-HT]ext more in the ventral hippocampus than in the frontal cortex. Furthermore, we demonstrate that SSRIs decrease immobility in the forced swimming test; this effect is absent in 5-HT1B knockout mice and blocked by GR 127935 in wild-type suggesting therefore that activation of 5-HT1B receptors mediate the antidepressant-like effects of SSRIs. Taken together these data demonstrate that 5-HT1B autoreceptors appear to limit the effects of SSRI on dialysate 5-HT levels particularly in the hippocampus while presynaptic 5-HT1B heteroreceptors are likely to be required for the antidepressant activity of SSRIs.
Cues of being watched enhance cooperation in a real-world setting

We examined the effect of an image of a pair of eyes on contributions to an honesty box used to collect money for drinks in a university coffee room. People paid nearly three times as much for their drinks when eyes were displayed rather than a control image. This finding provides the first evidence from a naturalistic setting of the importance of cues of being watched, and hence reputational concerns, on human cooperative behaviour.
MixtureTree Annotator: A Program for Automatic Colorization and Visual Annotation of MixtureTree

The MixtureTree Annotator, written in JAVA, allows the user to automatically color any phylogenetic tree in Newick format generated from any phylogeny reconstruction program and output the Nexus file. By providing the ability to automatically color the tree by sequence name, the MixtureTree Annotator provides a unique advantage over any other programs which perform a similar function. In addition, the MixtureTree Annotator is the only package that can efficiently annotate the output produced by MixtureTree with mutation information and coalescent time information. In order to visualize the resulting output file, a modified version of FigTree is used. Certain popular methods, which lack good built-in visualization tools, for example, MEGA, Mesquite, PHY-FI, TreeView, treeGraph and Geneious, may give results with human errors due to either manually adding colors to each node or with other limitations, for example only using color based on a number, such as branch length, or by taxonomy. In addition to allowing the user to automatically color any given Newick tree by sequence name, the MixtureTree Annotator is the only method that allows the user to automatically annotate the resulting tree created by the MixtureTree program. The MixtureTree Annotator is fast and easy-to-use, while still allowing the user full control over the coloring and annotating process.
Data-Driven Rule Mining and Representation of Temporal Patterns in Physiological Sensor Data

Mining and representation of qualitative patterns is a growing field in sensor data analytics. This paper leverages from rule mining techniques to extract and represent temporal relation of prototypical patterns in clinical data streams. The approach is fully data-driven, where the temporal rules are mined from physiological time series such as heart rate, respiration rate, and blood pressure. To validate the rules, a novel similarity method is introduced, that compares the similarity between rule sets. An additional aspect of the proposed approach has been to utilize natural language generation techniques to represent the temporal relations between patterns. In this study, the sensor data in the MIMIC online database was used for evaluation, in which the mined temporal rules as they relate to various clinical conditions (respiratory failure, angina, sepsis, .) were made explicit as a textual representation. Furthermore, it was shown that the extracted rule set for any particular clinical condition was distinct from other clinical conditions.
An investigation of force, surface roughness and chip in surface grinding of SKD 11 tool steel using minimum quantity lubrication-MQL technique

This research aimed to analyze the viability of the minimum quantity of lubricant (MQL) technique towards normal force, tangential force, surface roughness and chip formation in surface grinding of SKD 11 tool steel. The three surface grinding parameters were varied including the type of cooling method (MQL and dry), table speed, and depth of cut. Based on statistical analysis, depth of cut is the most influential factor which affects the four responses in both dry and MQL grinding. MQL could reduce normal force and tangential force considerably, but produce higher surface roughness. In MQL grinding, the chips removal took place mostly by shearing and fracturing.
Mobile Smart Grids: Exploiting the TV White Space in Urban Scenarios

Due to its attractive characteristics, the TV white space (TVWS) spectrum is considered the ideal candidate to enable the deployment of smart grid networks (SGNs) via cognitive radio paradigm. However, the intermittent availability of the TVWS spectrum as well as its scarcity in urban scenarios could compromise the tight smart grid requirements in terms of reliability, latency, and data rate. This degradation could be even more severe when mobile grid nodes, e.g., electric vehicles, are considered. Stemming from this, we first develop an analytical framework to account for the mobility in SG scenarios. Then, we design a switching procedure based on the use of two different bands: TVWS spectrum and Industrial, Scientific and Medical (ISM) spectrum. The switching procedure selects, among the available spectrum bands, the one maximizing the achievable throughput at an arbitrary SGN. Such a procedure accounts for the presence of interfering SGNs on the TVWS spectrum through both their traffic and mobility patterns. By wisely using both the ISM and the TVWS spectrum, the proposed switching procedure is able to: 1) increase the achievable data rate, and to 2) reduce the outage event rate, improving the reliability and the latency of the smart grid communications. Moreover, we show the performance of the proposed switching procedure depends largely on the time devoted to sense. Hence, the proper setting of such a parameter is critical for the performance of any SGN. For this, we derive an optimization criterion maximizing the throughput under the constraint of bounding the outage rate. The theoretical analysis is validated through extensive numerical simulations.

Additionally, through embedded monocular vision, on-site environmental information is collected as neural network input, so necessary joint trajectory is output for the movement. Simulations and experiment testify the efficiency of the method.
Impaired Neutrophil Chemotaxis in Two Patients with Mucolipidosis II

Mucolipidosis I1 (ML 11) is a rare autosomal recessive disorder characterized by coarse facial features, gingival hyperplasia, joint stiffness, skeletal abnormalities and psychomotor retardation. Hasilik e t al. (1) and Reitman et al. (2) found that N-acetyl-glucosaminylphosphotransferase activity was deficient in patients with ML 11. Recently, we have demonstrated that the deficiency of N-acetylglucosaminylphosphotransferase activity is easily detectable by using commercially obtainable UDP-N-ace ty l -~[U-~~c] glucosamine and a-methylmannoside (3). Patients with ML I1 are susceptible to infection, and most of them die between the ages of 3 and 8. Presently, there are only a few reports about immunological functions in patients with ML I1 (4, 5, 6). Neutrophil functions have not yet been investigated in patients with ML 11. In this study, we examined the immunological as well as neutrophil functions in two girls with ML 11.
