A Survey on Application Collusion Attacks on Android Permission-Mechanism

Considering the wide range of functionalities provided by smartphones, smartphone-users' privacy and security of their personal information is of vital importance. Android has been the most targeted platform for malware attacks, due to being the most popular platform, open source system and its vulnerable architecture. In this paper, we have studied about android permission mechanism, collusion attack, and covert and overt communication channels. Collusion attacks allow apps to indirectly execute operations, which they should not be able to execute, based on their declared permissions. For instance, disclosure of users' private data (e.g., contacts or GPS location) to a destined attacker, by apps that do not have direct access to such data or cannot directly establish remote connections. According to the survey(1), there's significant potential of collusion attacks and these attacks are really hard to detect, therefore it is considered to be a real threat to smartphone
Wide-band circularly polarized antenna for dual-band GPS receiver

In this letter, the design of a wide-band circularly polarized microstrip antenna with gain of more than 8dB is introduced. This antenna is designed for the global positioning satellite operations at 1227 MHz(L2) and 1575 MHz(L1). It has an advantage of a much wider band in both VSWR and 3dB axial-ratio compared with single-feed GPS antennas. Details of design, simulated results of this GPS antenna are presented and discussed. The results confirm the validity of this design which meet the requirement of GPS application.
Macrolide-resistant Staphylococcus aureus colonization in cystic fibrosis patients: is there transmission to household contacts?

OBJECTIVES Patients with cystic fibrosis (CF) are frequently colonized by macrolide-resistant Staphylococcus aureus, a result of maintenance macrolide therapy. As transmission of S. aureus between household contacts is common, we examined the prevalence of macrolide-resistant S. aureus colonization in CF patients on maintenance azithromycin therapy and their household contacts and compared this with the S. aureus macrolide resistance prevalence in the community. PATIENTS AND METHODS Sixty-five CF patients on maintenance macrolide therapy and 194 household contacts were screened for S. aureus colonization by culturing sputa, cough swabs and nasal swabs. Resistance to macrolide, lincosamide and methicillin was determined by disc diffusion tests. The prevalence of macrolide-resistant S. aureus colonization in both groups was compared with figures from a nationwide study into S. aureus carriership and resistance. To assess possible transmission, genotyping of S. aureus was performed using the spa-typing method. RESULTS Macrolide resistance among CF patients with S. aureus colonization was 69.6%; 75% of these isolates displayed lincosamide resistance too. Among household contacts, macrolide resistance prevalence did not differ significantly from resistance prevalence in the community (9.6% versus 6.3%; P = 0.358). No methicillin resistance was observed. No identical (macrolide-resistant and -susceptible) S. aureus genotypes were observed between CF patients and their household contacts except for one household, suggesting a probable transmission. CONCLUSIONS No significant increase in macrolide-resistant S. aureus colonization was observed among household contacts of CF patients on long-term azithromycin therapy. Transmission of macrolide-resistant S. aureus could not be proved by genotyping in the majority of households.
TOPS-Mode Raw Data Processing Using Chirp Scaling Algorithm

This paper presents four imaging approaches for terrain observation by progressive scans (TOPS)-mode SAR focusing, all of which take advantage of modified chirp scaling (CS) algorithms according to echo properties in TOPS. After adopting different azimuth preprocessing steps to resolve the aliased Doppler spectra, the resulting TOPS raw data can be handled by a classic CS processor. Unfortunately, the resulting images would appear back folding, if only a standard stripmap processor is adopted. To avoid or resolve azimuth back folding in the final focused TOPS SAR images, four modified CS algorithms are presented according to special properties of the slow time-frequency diagram in TOPS. Imaging results on point targets validate the presented imaging approaches.
Specificity of Ca2+ Signaling in Polarized Cells

ignaling specificity is now the central question in cellsignaling. Several aspects of the problem include thequestions of how receptors that use the samebiochemical pathway can generate agonist-specificsignals, and how divergent signaling pathways interact witheach other to form signaling networks (Weng et al., 1999;Hunter, 2000).

Physiological and biochemical factors responsible for boar taint

We used entire male pigs to: 1) compare different methods to analyse boar taint compounds; 2) evaluate the effects of raw potato starch (RPS), high amylose barley cultivar (Karmose), sire selection and live weight on the levels of boar taint compounds; 3) investigate the relationship between indolic compounds and testicular steroids by using an hCG injection model; 4) evaluate the effect of incubation with steroids and indolic compounds on CYP2A6 protein expression in hepatocytes; 5) investigate the relationship between testicular steroids and gene expression of hydroxysteroid dehydrogenases (3βHSD and 17βHSD) in entire male and castrated male pigs. The results showed that HPLC method and GC-MS method for fat androstenone analyses were comparable. HPLC and ELISA methods for fat androstenone analyses were well correlated (r = 0.90), but the result from the ELISA method was overestimated. HPLC and colorimetric method for fat skatole analyses were well correlated (r = 0.94) even though the two methods used different sample matrix. Plasma androstenone results determined by ELISA method with and without sample extraction were moderately correlated (r = 0.70). The results from analyses without sample extraction were 4 times higher than the results from analyses with sample extraction. Feeding RPS reduced fat skatole levels, but not fat androstenone and indole levels of entire male pigs. High amylose barley did not influence any of the boar taint compounds analyzed in fat (skatole, androstenone and indole). Androstenone levels in fat were higher at live weight 115 kg than at 90 kg, whereas fat skatole and indole levels did not differ between the two live weights. Sire selection based on plasma skatole levels significantly influenced skatole, androstenone and indole levels in fat in the progenies. Indole levels in plasma and in fat were significantly increased after hCG injection, and skatole levels in fat tended to be increased. This increase was associated with the abrupt increase of testicular steroids by hCG injection. An in vitro study showed that both skatole and indole at low concentrations (0-100 nM) induced cytochrome P450 2A6 (CYP2A6) protein expression in cultured hepatocytes, with a more prominent effect for indole. Androstenone at low concentration (0-100 nM) inhibited CYP2A6 protein expression. Testosterone and estrone sulfate (E1S) did not affect CYP2A6 protein expression. High fat androstenone levels were negatively associated with low 3βHSD gene expression in entire male pigs. Fat androstenone levels were also negatively associated with 17βHSD gene expression in liver but not in testis. The correlation between hepatic 17βHSD gene expression and plasma E1S was high. In addition, gene expression of 3βHSD and 17βHSD was highly correlated. Gene expressions of 3βHSD and 17βHSD in liver were much higher in surgically castrated and immunocastrated pigs than in entire male pigs with high fat androstenone levels. The gene expression of 3βHSD was generally much higher than 17βHSD both in liver and in testis.
3D flexible multichannel neural probe array

A 3D flexible multichannel microprobe array was designed, fabricated and tested. Since each probe had several recording pads, the probe array could be used to measure neural activity at various depths in the brain. They were batch fabricated with interconnections, using a specific folding process to fold the planar probe structures. This flexible probe array was inserted into a rat's brain without fracturing and was successfully used to measure neural signals.
Cell Mechanobiology in Regenerative Medicine: Lessons from Cancer

The stem cell “niche” refers to the collective set of cell-extrinsic inputs that controls the functions of stem cells in vivo.1,2 The key regulatory mechanisms within the niche include presentation of soluble and immobilized molecules such as growth factors and cytokines, direct interactions with other cells (e.g., stromal cells), and adhesion to the extracellular matrix (ECM). These diverse inputs are regulated and integrated in a temporally and spatially dynamic fashion to control self-renewal and differentiation, the two hallmark properties of stem cells. Traditionally, the field has approached this subject from a paradigm that is largely biochemical in nature, focusing on the regulatory roles of soluble and membranebound ligands on stem cell behavior. While it is clear that these inputs are indeed important, it is also increasingly being recognized that mechanical and other types of biophysical interactions between cells with their extracellular milieu can profoundly influence stem cell behavior. This idea is an extension of a broader awareness that many cell types can sense and apply forces to their surroundings,3 and that the mechanical interactions of cells with their environment are critical regulators of function in physiology and disease, a concept now widely referred to as “cellular mechanobiology. ”4,5 Early efforts in this area have demonstrated that, similar to other cell types in tissue, stem cells are also influenced by mechanical forces and that biophysical signaling can control stem cell self-renewal and differentiation.6−8 These effects are mediated by intracellular signaling pathways that transduce force cues into biochemical signals that in turn drive fundamental cellular processes such as cell adhesion, motility, proliferation, and differentiation.9,10 Despite the growing interest in the mechanobiology of stem cells, our understanding of how these effects may be incorporated into a broader understanding of stem cell biology or leveraged to enhance stem cell-based therapies remains very limited. In addition, the mechanistic details of force transduction 30
Design of Design of Design of Design of a a a a Real Time Situation Awareness and Crisis Management System

ABSTRACTABSTRACTABSTRACT Crisis Management and Situation Awareness are two increasingly important topics in today’s world. Nigeria, like the rest of the world, is exposed to a wide range of natural or human induced disasters. While some of these disasters are rapid, others are slow-onset, resulting in catastrophic situations leading to loss of lives, property and degradation of environment. Some of the disasters are drought, desertification, flooding, epidemics, coastal erosion, dam failure, building collapse, oil spillage, maritime collision or accident, bomb explosion, communal clash, fire, air crashes and boat mishap and many more. This paper presents the design of SITUWARE, a situation awareness application that takes advantage of the vast usage of mobile and portable electronic devices to provide handy, prompt, precise and instructional information about critical situations around people. PHP was used as a server side scripting language and MySQL as database platform for the system. We note however, the inability to guarantee the integrity and dependability of information retrieved from social medial as potential limitation of the work.
Mortality and the attribution of health problems to aging among older adults.

This study examined the association between mortality and attributing health problems to aging among 1391 respondents from the Longitudinal Study of Aging who indicated difficulty with activities of daily living. Of this number, 72 persons attributed impairment primarily to "old age. " Logistic regression controlling for demographics, physical health problems, self-rated health, and social involvements showed an association with mortality (adjusted odds ratio = 1.78, CI = 1.05, 3.00). Attributing health problems to aging may carry a risk of adverse health events.
Automatic burn area identification in color images

This papers presents the use of color imaging as a starting point of burn wound evaluation, by the discrimination between healthy skin and burn wound. The skin/burn area identification is performed pixel-wise, according to the properties of an entire encompassing patch. The classification is learned under a supervised scenario, according to a ground truth defined by specialist surgeons from a large pediatric case database, by a deep learned convolutional neural network. The database is extensive and was recorded over several months in real, hospital conditions The proposed approach achieves an overall performance comparable to the literature-reported average performance of a specialist surgeon.
An Efficient Tag Recommendation Method using Topic Modeling Approaches

Software information sites such as Stack Overflow, Super User, and Ask Ubuntu allow users to post software-related questions, answer the questions asked by other users, and add tags to their questions. Tagging is a popular system across web communities because allowing users to classify their contents is less costly than employing an expert to categorize them. However, tagging systems suffer from the problem of the tag explosion and the tag synonym. To solve these problems, we propose a tag recommendation method using topic modeling approaches. Topic models have advantages of dimensionality reduction and document similarity. We also emphasize highest topics in calculating document similarity to retrieve more relevant documents. Our tag recommendation method considers the document similarity and the historical tag occurrence to calculate tag scores. Experiment results show that emphasizing highest topic distributions increases overall performance of tag recommendation.
The Unit of Speech Encoding: The Case of Romanian

The number of units in an utterance determines how much time speakers require to physically plan and begin their production [1]-[2]. Previous research proposed that the crucial units are prosodic i.e., Phonological Words (PWs), not syntactic or morphological [3]. Experiments on Dutch using a prepared speech paradigm claimed to support this view [4]-[5]; however, compounds did not conform to predictions and required the introduction of a different way of counting units. Since two PWs in compounds patterned with one PW, with or without clitics, rather than a phrase containing two PWs, a recursive PW’ was invoked. Similar results emerged using the same methodology with compounds in Italian [6], and it was thus proposed that the relevant unit for speech encoding is not the PW, but rather the Composite Group (CompG), a constituent of the Prosodic Hierarchy between the PW and Phonological Phrase that comprises both compounds and clitic constructions [7]. We further investigate the relevant unit for speech encoding using the same methodology in Romanian. Similar findings support the CompG as the speech planning unit since, again, compounds with two PWs pattern with single words and clitic constructions, not Phonological Phrases which also contain two PWs.
Clinical and surgical experience with Wilms' tumor. Long-term results of a single institution.

BACKGROUND Although the NWTSG and SIOP studies have included the largest number of patients, several individual institutions have made likewise important contributions to the optimization of Wilms' tumor therapy. The purpose of this study is to present our personal experience obtained in the last 42 years by treating Wilms' tumor in childhood. PATIENTS AND METHODS Throughout the period 1965-2006, 65 children with histological confirmation of Wilms' tumour were treated in the Department of Urology, University of Erlangen Medical Centre. The records of all patients presenting to our institution with Wilms' tumour were examined. RESULTS The results obtained by this study group indicate that prognosis according to age demonstrated no significance, but prognosis according to tumor size, lymph node involvement and distant metastasis was significant. After a 10-year follow-up, our data revealed an 89.4% survival rate. Furthermore, the statistical evaluation performed in order to evaluate the significance of surgical complications following neoadjuvant therapy in comparison to non adjuvant therapy, indicates that there is a significant increase in complications in patients who are not treated with neoadjuvant therapy. DISCUSSION Although clinicians in the U.S.A. and Europe have different philosophies on preoperative chemotherapy, most patients with Wilms' tumor survive long term, regardless of the sequence of therapeutic interventions. In the absence of a clear choice between up-front nephrectomy and preoperative chemotherapy, it is reasonable to base the timing of resection on factors such as tumor size, the patient's clinical condition, and the experience of the surgeon.
Real-Time Detection of Unstable Control Loop Behavior in a Feedback Active Noise Cancellation System for In-Ear Headphones

Active noise controls are used in a wide field of applications to cancel out unwanted surrounding noise. Control systems based on the feedback structure however have the disadvantage that they may become unstable during run-time due to changes in the control path—in this context including the listener’s ear. Especially when applied to active noise cancellation (ANC) headphones, the risk of instability is associated with the risk of harmful influence on the listener’s ear, which is exposed to the speaker in striking distance. This paper discusses several methods to enable the analysis of a feedback ANC system during run-time to immediately detect instability. Finally, a solution is proposed, which identifies the open loop behavior parametrically by means of an adaptive filter to subsequently evaluate the coefficients regarding stability.
Richter syndrome in chronic lymphocytic leukemia: updates on biology, clinical features and therapy

Abstract Richter syndrome (RS) or Richter transformation is the development of secondary aggressive lymphoma in the setting of underlying chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Most frequently CLL transforms into diffuse large B-cell lymphoma (DLBCL) (90%) and rarely (10%) into Hodgkin lymphoma, termed Hodgkin variant of Richter syndrome (HvRS). RS is generally characterized by an aggressive clinical course and poor prognosis. In recent years, major advances have been made in understanding genetic events which relate to the progression of CLL or transformation into RS. Better understanding of the molecular pathways has revealed that RS is not a single homogeneous entity. The majority of cases are clonally related to the original CLL clone, while a minority develop from an unrelated clone. This review summarizes new data relating to the molecular biology and the genetic/epigenetic changes occurring during Richter transformation, and also considers the clinical features and therapy for both DLBCL-RS and Hodgkin variant-RS.

Dynamic Power Consumption Optimization for Inductive-Coupling based Wireless 3D NoCs

Inductive-coupling is yet another 3D integration technique that can be used to stack more than three knowngood-dies in a SiP without wire connections. Its power consumed for communication by inductive coupling link is one of big problems. A dynamic on/off link control for topology-agnostic 3D NoC (Network on Chip) architecture using inductive-coupling is proposed. The proposed low-power techniques stop the transistors by cutting off the bias voltage in the transmitter of the wireless vertical links only when their utilization is higher than the threshold. Meanwhile, the whole wireless vertical link will be shut down when the utilization is lower than the threshold in order to reduce the power consumption of wireless 3D NoCs. Full-system many-core simulations using power parameters derived from a real chip implementation show that the proposed low-power techniques reduce the power consumption by 43.8–55.0%, while the average performance overhead is 1.4% in wireless topology-agnostic 3D NoC.

MINT / VXF-A High-Performance Computing Framework for Interactive Multimedia

The development of a cross-disciplinary system for immersive, real-time multimedia requires the solution to several challenges simultaneously. Systems for interactive tiled displays range from low-level solutions via ChromiumGL [5] to distributed scene graphs with OpenSG and CGLX [1]. Libraries such as DII and SuperCollider are designed for input device abstraction and audio respectively[6]. However, integrated multimedia systems covering all of these needs while providing built-in, dynamic primitives for interdisciplinary research do not yet exist. We present MINT/VXF, a framework for high-performance visual computing and research in interactive multimedia. Built using the MINT core event system, GameX graphics engine [3], and NVIDIA’s CUDA for hardware-based computing, MINT/VXF introduces a novel scene graph architecture which abstracts GPU-based node evaluation to selectively leverage GPU resources in distributed multimedia systems.
A review of dynamic and intelligent honeypots

A honeypot is a computer resource that is deployed in the network to attract attackers. It is designed to be attacked and misused by them. The functionality of a honeypot depends on its technical configuration made by the system administrators. To properly blend in with the environment, a honeypot must be configured to mimic the production hosts within the network environment which is very dynamic. This paper reviews research on dynamic and intelligent honeypots.
