THINPLE - the new online Sociality is built on top of NFC-based Contacts

The rapid densification of today's online social networks is progressively draining their early value of mirroring real life sociality. This paper describes THINPLE, a novel mobile computing app aiming at building a protected and trusted online social space where the growth of the sociality of a person is only fuelled by contacts in the physical world. THINPLE exploits each physical contact, through the short radio range of Near Field Communication, NFC, to capture the explicit willingness and trustworthiness to initiate a online relationship. Moreover, through physical contacts, inanimate objects of the real world can be added to the online sociality of individuals, thus turning into practice the concept of Internet of things and people.
Iterative Locality Preserving Projection for Image Retrieval

Recently there has been considerable interest in subspace learning for efficient multimedia information retrieval. The typical subspace learning for discovering the intrinsic geometrical structure include Principal Component Analysis (PCA) and Locality Preserving Projections (LPP). PCA discover the global Euclidean structure while LPP discovers the local manifold structure. LPP is based on a nearest neighbor graph which models the local geometrical structure of the image manifold. However, such a graph can not always accurately estimate the intrinsic manifold structure. In this paper, we propose a novel algorithm called Iterative Locality Preserving Projections (ILPP). ILPP iteratively updates the nearest neighbor graph, so that it can better model the intrinsic manifold structure. We compared our algorithm with PCA and LPP on the COREL image database. Experimental results show that our algorithm outperforms PCA and LPP for image retrieval.
Lipoprotein(a) and Atherosclerotic Cardiovascular Disease: Where Do We Stand?

Lipoprotein(a) [Lp(a)] consists of a low-density lipoprotein-like molecule and an apolipoprotein(a) [apo(a)] particle. Lp(a) has been suggested to be an independent risk factor of atherosclerotic cardiovascular disease (ASCVD). Lp(a) plasma levels are considered to be 70–90% genetically determined through the codominant expression of the LPA gene. Therefore, Lp(a) levels are almost stable during an individual’s lifetime. This lifelong stability, together with the difficulties in measuring Lp(a) levels in a standardized manner, may account for the scarcity of available drugs targeting Lp(a). In this review, we synopsize the latest data regarding the structure, metabolism, and factors affecting circulating levels of Lp(a), as well as the laboratory determination measurement of Lp(a), its role in the pathogenesis of ASCVD and thrombosis, and the potential use of various therapeutic agents targeting Lp(a). In particular, we discuss novel agents, such as antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) that are currently being developed and target Lp(a). The promising role of muvalaplin, an oral inhibitor of Lp(a) formation, is then further analyzed.
Building an Ontology-Based Multilingual Lexicon for Word Sense Disambiguation in Machine Translation

Word sense disambiguation (WSD) requires the establishment of a list of the different meanings of words. WSD efforts in machine translation require, in addition, the equivalent translation words in target languages. To facilitate WSD in machine translation systems, we propose the construction of an ontology-based multilingual lexicon, from various existing language resources, as an alternative to existing hierarchical lexicons such as WordNet and Roget’s Thesaurus. Apart from providing equivalent words from different languages, the lexicon will be used to extend a WSD algorithm that calculates lexical conceptual distance data. The information in the lexicon to be constructed can also be used for other natural language processing tasks.

Explicit formula for the generating series of diagonal 3D rook paths

Let $a_n$ denote the number of ways in which a chess rook can move from a corner cell to the opposite corner cell of an $n \times n \times n$ three-dimensional chessboard, assuming that the piece moves closer to the goal cell at each step. We describe the computer-driven \emph{discovery and proof\/} of the fact that the generating series $G(x)= \sum_{n \geq 0} a_n x^n$ admits the following explicit expression in terms of a Gaussian hypergeometric function: \[ G(x) = 1 + 6 \cdot \int_0^x \frac{ \,\pFq21{1/3}{2/3}{2} {\frac{27 w(2-3w)}{(1-4w)^3}}}{(1-4w)(1-64w)} \, dw. \]
Shock‐induced microtextures in lunar apatite and merrillite

Apatite and merrillite are the most common phosphate minerals in a wide range of planetary materials and are key accessory phases for in situ age dating, as well as for determination of the volatile abundances and their isotopic composition. Although most lunar and meteoritic samples show at least some evidence of impact metamorphism, relatively little is known about how these two phosphates respond to shock‐loading. In this work, we analyzed a set of well‐studied lunar highlands samples (Apollo 17 Mg‐suite rocks 76535, 76335, 72255, 78235, and 78236), in order of displaying increasing shock deformation stages from S1 to S6. We determined the stage of shock deformation of the rock based on existing plagioclase shock‐pressure barometry using optical microscopy, Raman spectroscopy, and SEM‐based panchromatic cathodoluminescence (CL) imaging of plagioclase. We then inspected the microtexture of apatite and merrillite through an integrated study of Raman spectroscopy, SEM‐CL imaging, and electron backscatter diffraction (EBSD). EBSD analyses revealed that microtextures in apatite and merrillite become progressively more complex and deformed with increasing levels of shock‐loading. An early shock‐stage fragmentation at S1 and S2 is followed by subgrain formation from S2 onward, showing consistent decrease in subgrain size with increasing level of deformation (up to S5) and finally granularization of grains caused by recrystallization (S6). Starting with 2°–3° of intragrain crystal‐plastic deformation in both phosphates at the lowest shock stage, apatite undergoes up to 25° and merrillite up to 30° of crystal‐plastic deformation at the highest stage of shock deformation (S5). Merrillite displays lower shock impedance than apatite; hence, it is more deformed at the same level of shock‐loading. We suggest that the microtexture of apatite and merrillite visualized by EBSD can be used to evaluate stages of shock deformation and should be taken into account when interpreting in situ geochemically relevant analyses of the phosphates, e.g., age or volatile content, as it has been shown in other accessory minerals that differently shocked domains can yield significantly different ages.
A prism-based system for multispectral video acquisition

In this paper, we propose a prism-based system for capturing multispectral videos. The system consists of a triangular prism, a monochrome camera, and an occlusion mask. Incoming light beams from the scene are sampled by the occlusion mask, dispersed into their constituent spectra by the triangular prism, and then captured by the monochrome camera. Our system is capable of capturing videos of high spectral resolution. It also allows for different tradeoffs between spectral and spatial resolution by adjusting the focal length of the camera. We demonstrate the effectiveness of our system with several applications, including human skin detection, physical material recognition, and RGB video generation.
Using social network theory for modeling human mobility

Human mobility modeling plays an essential role in accurately understanding the performance of data forwarding protocols in mobile networks and has been attracting increasing research interest in recent years. People's movement behaviors are strongly affected by their social interactions with each other, which, however, are not sufficiently considered in most existing mobility models. Recent studies in social network theory have provided many theoretical and experimental results, which are useful and powerful for modeling the realistic social dimension of human mobility. In this article we present a novel human mobility model based on heterogeneous centrality and overlapping community structure in social networks. Instead of extracting communities from artificially generated social graphs, our model manages to construct the k-clique overlapping community structure which satisfies the common statistical features observed from distinct real social networks. This approach achieves a good trade-off between complexity and reality. The simulation results of our model exhibit characteristics observed from real human motion traces, especially heterogeneous human mobility popularity, which has significant impact on data forwarding schemes but has never been considered by existing mobility models.
Nonmyeloablative Transplantation

High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation has been explored as a method to enhance the efficacy of chemotherapy for advanced solid tumors. The failure of autologous hematopoietic stem cell transplantation to prolong survival in patients with metastatic solid tumors has sparked interest recently in studies exploring the potential of allogeneic hematopoietic stem cell transplantation for such patients. Allogeneic hematopoietic stem cell transplantation is widely accepted as a potent form of immunotherapy capable of curing patients with chemotherapy-refractory hematologic malignancies. However, it was not until the end of the 20th century that investigators initiated trials to test the potential of allogeneic hematopoietic stem cell transplantation as immunotherapy in malignancies of epithelial origin. Early pilot trials have established proof-of-principle that graft-versus-tumor effects can induce complete or partial remission in some treatment-refractory metastatic solid tumors. In this review, we discuss the rationale for pilot trials investigating the potential of nonmyeloablative allogeneic hematopoietic stem cell transplantation in advanced cytokine-refractory renal cancer, highlighting the preliminary success, limitations, and future clinical directions of this approach.
The method of elf-files identification based on the metric classification algorithms

When performing the internal audit of computer equipment an important problem is to identify the elf (executable and linkable format) files stored on the investigated hard drive. To solve this problem, we propose a method of identification of unknown elf-ffles based on the metric classification algorithms. The method consists of three stages. On the first stage the preparation of the training sample by the disassembly of each file and submitting it in the form of an ordered set of the 118 elements is implemented. Each of these elements is the frequency of occurrences of the 118 most commonly used commands in the assembler code. Each program in the sample is represented by several sets, corresponding to different versions or operating systems in which this software is installed. Then, the Minkowski metric of each sample file and identifiable file is calculated. For the method of potential functions the selection of the reference elements of each set is obtained. On the third stage using the metric classification algorithms we evaluate affiliation of the identifiable file for a particular program from the sample. To approbate proposed method the experiment with the use of this method was conducted; results showing the accuracy of identification of elf-files was equal to 89,60% were obtained. The results indicate that this method is applicable in problems of identification of elf-files while conducting the internal audit of computer equipment. The advantages of the method are the accuracy of program identification regardless of the elf-files versions in the Linux operating systems. The ease of implementation of our method and the identification execution speed can be used not only in tasks of internal audit, but also in other tasks of computer forensics.
A 2.89  $\mu $ W Dry-Electrode Enabled Clockless Wireless ECG SoC for Wearable Applications

This paper presents a fully integrated wireless electrocardiogram (ECG) SoC implemented in asynchronous architecture, which does not require system clock as well as off-chip antenna. Several low power techniques are proposed to minimize power consumption. At the system level, a newly introduced event-driven system architecture facilitates the asynchronous implementation, thus removes the system clock leading to a true ECG-on-chip solution. A DC-coupled analog front-end is introduced together with a baseline stabilizer to boost the input impedance to 3.6 GQ and mitigate the electrode offset, which is less sensitive to motion artefact and contact impedance imbalance, making it well suited for dry-electrode based applications. Level-crossing analog-to-digital converter (LC-ADC) is employed to take the advantage of burst nature of ECG signal leading to at least 5 times reduction in sampling points compared to Nyquist sampling. A digitally implemented impulse-radio ultra-wideband transmitter is seamlessly integrated with LC-ADC and an on-chip antenna for wireless communications. Implemented in 0.13 μm CMOS technology, the ECG-on-chip consumes 2.89 μW under 1.2 V supply while transmitting the raw ECG data, which attains one order of magnitude lower than the current state-of-the-art designs. The fully integrated ECG SoC requires no external clocks and off-chip antenna, making it a good candidate for low cost and disposable wireless ECG patches, such as epidermal electronics.
Exploring ambient visualizations of context information

In this paper we investigate how ambient displays can be used to share context information. Currently, many personal devices provide context information, such as location or activity, and at the same time the number of ambient displays is increasing. We developed two prototypes for visualizing contextual information and initially explored the suitability of these in an online study. Additionally, we investigated which parameters are important for users when sharing personal context. Based on our findings we discuss guidelines for the design of ambient displays for context sharing.
Exploring evolutionary learning in a simulated hockey environment

As a test bed for studying evolutionary and other machine learning techniques, we have developed a simulated hockey game called Shock in which players attempt to shoot a puck into their enemy's goal during a fixed time period. Multiple players may participate-one can be controlled by a human user, while the others are guided by artificial controllers. In previous work, we introduced the Shock environment and presented players that received global input (as if from an overhead camera) and were trained on a restricted task, using an evolutionary hill climbing algorithm, with a staged learning approach (A. Blair and E. Sklar, 1998). Here, we expand upon this work by developing players which instead receive input from local, Braitenberg-style sensors (V. Braitenberg, 1984). These players are able to learn the task with fewer restrictions, using a simpler fitness measure based purely on whether or not a goal was scored. Moreover, they evolve to develop robust strategies for moving around the rink and scoring goals.
Consórcios de gramíneas anuais de inverno com e sem fertilização.

The objective of this study was to evaluate the forage yield in diﬀerent winter annual grass multi-cropping with and without fertilizaton. One experiment was carried out from April to October 2010 using the experimental design of complete blocks with four replications and a factorial scheme 3 x 2. Three pastures were evaluated: rye ( Secale cereale L.), rye + black oat ( Avena strigosa Schreb.) and rye + black oat + ryegrass ( Lolium multﬂorum Lam.) with and without fertlizaton. No interacton was observed between multi-cropping and fertilization factors. The highest pasture yield was verifed in the multi-cropping of the three species evaluated. Fertlizaton increased dry mass yield by 47%.
Analysis of various transient phenomena and co-existing periodic spike-trains in simple digital spike maps

This paper studies various transient- and steady-state spike-trains generated by the digital spike map: a simple digital dynamical system from a set of one-dimensional lattice points to itself. In order to consider the spike-trains, three feature quantities are presented: 1) the number of periodic spike-trains that can characterize richness of the steady states, 2) the concentricity of spike-position transition that can characterize transition of map, and 3) the concentricity of direct transition to the periodic spike-trains that can characterize local stability of the steady state. Based on these quantities, we give basic classification of dynamics of spike-trains and demonstrate typical examples. The results can be basic information to develop study of digital spike systems and their applications.
A Single-Phase Brushless DC Motor With Improved High Efficiency for Water Cooling Pump Systems

This research deals with the optimization of a single-phase brushless DC motor (BLDCM) by substituting a commercial single-phase BLDCM for pump application in order to satisfactorily improve its efficiency regarding the required performance of a motor for pump systems (pump load 1,800 rpm, at 2 Nmm). The reliability of the results is verified between simulation and experiment using performance tests. In the sampling process, latin hypercubic sampling (LHS), the subject of many experiments, is usually used. However, this method requires a great deal of time and expense. This paper utilizes the table of orthogonal array in order to use the smallest possible number of experiments. In addition, a metamodel with second approximation polynomials is made using response surface methodology (RSM). The adjusted coefficients of multiple determinations which shows the reliability of the metamodel (multiobjective functions) is 100%. This result shows that the table of orthogonal array with the smallest number of experiments is suitable for sampling. The genetic algorithm (GA) is implemented to search for optimum solutions on the constructed metamodel which consists of two objective functions. With the optimal design set, predicted results of the GA are better than the generalized reduced gradient (GRG) algorithm. Nevertheless, verification results of the GRG are better than the GA. This result has an error within 1%.
A coreless maximum power point tracking circuit of thermoelectric generators for battery charging systems

We have proposed and fabricated a maximum power point tracking (MPPT) circuit for thermoelectric generator (TEG) without digital controller unit. The experimental and simulation results from the proposed MPPT circuit employing the boost cascaded-with-buck converter dealt with rapid variation of temperature and abrupt changes of load current have shown that the proposed method allows stable operation with high power transfer efficiency. The main advantage of proposed method is analog tracking circuit by sampling half Voc level without DSP or micro controller unit for calculating peak power point by iterative methods. The proposed MPPT circuit has a merit in cost and miniaturization of a system compared to conventional MPPT algorithms.
A comparison between zinc sulfate and chlorhexidine gluconate mouthwashes in the prevention of chemotherapy-induced oral mucositis

Background and the Purpose of the Study Patients undergoing high-dose chemotherapy for hematological malignancies are susceptible to development of oral mucositis, and no effective modality has been reported for its prophylaxis and treatment. The aim of this study was to evaluate the effectiveness of zinc mouthwash on chemotherapy-induced oral mucositis lesions. Methods In this double-blind randomized trial, patients under chemotherapy for acute leukemia were divided into two test and control groups of 15 patients each. The groups were homogeneous with respect to medical history, tumor characteristics, and therapeutic details. The test group received 10ml 0.2% zinc sulfate mouthwash, and the control group received 10ml 0.2% chlorhexidine gluconate mouthwash, twice a day for a period of two weeks. Spijkervet scale was used to grade the severity of mucositis at every other week during eight weeks. The severity scores were analyzed with repeated measure ANOVA using SPSS 13.0 computer software. Results Mean severity scores were generally lower in the test group compared to the controls at all four time intervals evaluated; but only, the differences in weeks of 2 and 3 were statistically significant (P=0.025). Conclusion Zinc mouthwash used in conjunction with chemotherapy may reduce the severity of oral mucositis lesions in patients with leukaemia.
Comparative Study of Hypolipidemic Profile of Resinoids of Commiphora mukul/Commiphora wightii from Different Geographical Locations

The antihyperlipidemic activity of resinoids of guggul (Commiphora mukul/Commiphora wightii), belonging to family Burseraceae (Genus: Commiphora), collected from different parts of India (Gujarat, Madhya Pradesh and Rajasthan), was studied on cholesterol-rich high fat diet-induced model of hyperlipidemia in rats. The resinoids of these exudates were prepared in ethyl acetate and ethyl alcohol. The physicochemical characterization of these resinoids was carried out to determine their appearance, %yield, %moisture, %ash, acid value (mg/KOH/g), saponification value (mg/KOH/g), ester value and iodine value (g/g). Antihyperlipidemic study was carried out on all resinoids in high fat diet induced model of hyperlipidemia in Wistar albino rats. The result demonstrated that the resinoids of exudates of Commiphora wightii and Commiphora mukul, collected from Gujarat and extracted in ethyl acetate, and the resinoids of exudates of Commiphora mukul, collected from Madhya Pradesh and extracted in ethyl acetate, possessed significantly higher antihyperlipidemic activity compared with other resinoids, which may be due to regional/geographical variations.
On Acceptability in Abstract Argumentation Frameworks with an Extended Defeat Relation

Defeat between arguments is established by a combination of two basic elements: a conflict or defeat relation, and a preference relation on the arguments involved in this conflict. We present a new abstract framework for argumentation where two kinds of defeat are present, depending on the outcome of the preference relation: an argument may be a proper defeater or a blocking defeater of another argument. An operator is used to characterize the set of accepted arguments. This operator also provides a method for identifying controversial situations.
