Efficacy and safety of trabectedin as an early treatment for advanced or metastatic liposarcoma and leiomyosarcoma.

AIMS We aimed to evaluate the effect of prior chemotherapies on the outcomes of patients with liposarcoma and leiomyosarcoma treated with trabectedin as a 24-h infusion every 3 weeks. PATIENTS & METHODS Data from 129 patients who received trabectedin as second-line treatment following failure with an anthracycline/ifosfamide and those who had received at least two lines of prior chemotherapy were analyzed. RESULTS Forty seven patients received one prior regimen (group A) and 82 patients received at least two lines of chemotherapy (group B). A favorable trend in median time to progression (4.4 vs 3.0 months), progression-free survival (4.4 vs 2.6 months) and overall survival (17.4 vs 13.3 months) was found in group A. A trend toward higher overall response rate (6.4 vs 4.9%) and disease control rate (34.0 vs 26.8%) also favored group A. Both groups had equivalent safety profiles. CONCLUSION All efficacy outcomes were better in patients who received trabectedin as second-line treatment compared with patients with more extensive prior therapy.
Intensity of renal support in critically ill patients with acute kidney injury.

BACKGROUND The optimal intensity of renal-replacement therapy in critically ill patients with acute kidney injury is controversial. METHODS We randomly assigned critically ill patients with acute kidney injury and failure of at least one nonrenal organ or sepsis to receive intensive or less intensive renal-replacement therapy. The primary end point was death from any cause by day 60. In both study groups, hemodynamically stable patients underwent intermittent hemodialysis, and hemodynamically unstable patients underwent continuous venovenous hemodiafiltration or sustained low-efficiency dialysis. Patients receiving the intensive treatment strategy underwent intermittent hemodialysis and sustained low-efficiency dialysis six times per week and continuous venovenous hemodiafiltration at 35 ml per kilogram of body weight per hour; for patients receiving the less-intensive treatment strategy, the corresponding treatments were provided thrice weekly and at 20 ml per kilogram per hour. RESULTS Baseline characteristics of the 1124 patients in the two groups were similar. The rate of death from any cause by day 60 was 53.6% with intensive therapy and 51.5% with less-intensive therapy (odds ratio, 1.09; 95% confidence interval, 0.86 to 1.40; P=0.47). There was no significant difference between the two groups in the duration of renal-replacement therapy or the rate of recovery of kidney function or nonrenal organ failure. Hypotension during intermittent dialysis occurred in more patients randomly assigned to receive intensive therapy, although the frequency of hemodialysis sessions complicated by hypotension was similar in the two groups. CONCLUSIONS Intensive renal support in critically ill patients with acute kidney injury did not decrease mortality, improve recovery of kidney function, or reduce the rate of nonrenal organ failure as compared with less-intensive therapy involving a defined dose of intermittent hemodialysis three times per week and continuous renal-replacement therapy at 20 ml per kilogram per hour.

Is CO2 an Indoor Pollutant? Direct Effects of Low-to-Moderate CO2 Concentrations on Human Decision-Making Performance

Background: Associations of higher indoor carbon dioxide (CO2) concentrations with impaired work performance, increased health symptoms, and poorer perceived air quality have been attributed to correlation of indoor CO2 with concentrations of other indoor air pollutants that are also influenced by rates of outdoor-air ventilation. Objectives: We assessed direct effects of increased CO2, within the range of indoor concentrations, on decision making. Methods: Twenty-two participants were exposed to CO2 at 600, 1,000, and 2,500 ppm in an office-like chamber, in six groups. Each group was exposed to these conditions in three 2.5-hr sessions, all on 1 day, with exposure order balanced across groups. At 600 ppm, CO2 came from outdoor air and participants’ respiration. Higher concentrations were achieved by injecting ultrapure CO2. Ventilation rate and temperature were constant. Under each condition, participants completed a computer-based test of decision-making performance as well as questionnaires on health symptoms and perceived air quality. Participants and the person administering the decision-making test were blinded to CO2 level. Data were analyzed with analysis of variance models. Results: Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06–0.56), but performance on the focused activity scale increased. Conclusions: Direct adverse effects of CO2 on human performance may be economically important and may limit energy-saving reductions in outdoor air ventilation per person in buildings. Confirmation of these findings is needed.
Secondary lymphoid tissue chemokine (SLC/CCL21)/CCR7 signaling regulates fibrocytes in renal fibrosis

Fibrocytes are a distinct population of bloodborne cells that share markers of leukocytes as well as mesenchymal cells. We hypothesized that CCR7-positive fibrocytes migrate into the kidney in response to secondary lymphoid tissue chemokine (SLC/CCL21) and contribute to renal fibrosis. To investigate this hypothesis, renal fibrosis was induced by unilateral ureteral obstruction in mice. A considerable number of fibrocytes dual-positive for CD45 and type I collagen (ColI) or CD34 and ColI infiltrated the interstitium, reaching a peak on day 7. Most fibrocytes were positive for CCR7, and CCL21/CCR7 blockade reduced the number of infiltrating fibrocytes. CCL21 and MECA79 dual-positive vessels were also detected in the interstitium. The blockade of CCL21/CCR7 signaling by anti-CCL21 antibodies reduced renal fibrosis, which was confirmed by a decrease in fibrosis in CCR7-null mice with concomitant reduction in renal transcripts of pro α1 chain of ColI and TGF-β1. The number of F4/80-positive macrophages decreased along with renal transcripts of monocyte chemoattractant protein 1 (MCP-1/CCL2) after the blockade of CCL21/CCR7 signaling. These findings suggest that CCR7-positive fibrocytes infiltrate the kidney via CCL21-positive vessels, thereby contributing to the pathogenesis of renal fibrosis. Thus, the CCL21/CCR7 signaling of fibrocytes may provide therapeutic targets for combating renal fibrosis.

Sux array is a compact data structure for searching matched strings from text databases. It is an array of pointers and stores all suxes of a text in lexicographic order. Because its memory requirement is less than tree structures, it is eective for large databases. Moreover, constructing the sux array is used in the Block Sorting compression scheme. We compare algorithms for constructing sux arrays on speed and required memory and propose a fast and memory ecient algorithm by combining them. It is eective when the length of repeated strings in a text is large.
Modelling Second-Order Volumetric Features

Model creation using SMS's volumetric primitives revealed that many models lacked the highly salient visual details representable using the surface and space curve primitives, although the first-order mass distribution of the features was well characterized. This paper introduces eight second-order volumetric features that add detail to models, as might be required in a recognition scheme that used conceptual scale.
The importance of the normalizing channel in log-chromaticity space

The log-chromaticity space (LCS) is a color space with excellent illumination-invariant properties. When converting RGB colors to LCS, there exist four different options for choosing the normalizing channel. For classification applications, we analyze the impact of the normalizer on the distribution of colors in LCS. Based on synthetic and real image data we show that the geometric mean does not introduce a bias to the color clusters and always results in an intermediate clustering performance. However, data-specific selection of the normalizing channel can further improve the results. For instance, for skin classification we show that using the blue channel as denominator results in a recognition improvement of about 25.9% compared to the red channel (worst result). In comparison to the geometric mean and the green channel, the two most popular denominators, the performance increase is 12.9% and 2.9%.
Coffee and tea intake and the risk of myocardial infarction.

The authors investigated the association of caffeinated coffee, decaffeinated coffee, and tea with myocardial infarction in a study of 340 cases and age-, sex-, and community-matched controls. The odds ratio for drinking > or = 4 cups/day of caffeinated coffee versus drinking < or = 1 cup/week was 0.84 (95% confidence interval (CI) 0.49-1.42) after adjustment for coronary risk factors (1 cup = 237 ml). The odds ratio for drinking > 1 cup/day of decaffeinated coffee versus nondrinkers was 1.25 (95% CI 0.76-2.04). For tea, the odds ratio for drinking > or = 1 cup/day versus nondrinkers was 0.56 (95% CI 0.35-0.90). In these data, only tea was associated with a lower risk of myocardial infarction.
An improved distributed dynamic channel assignment scheme for dense WLANs

The popularity of wireless local area networks (WLANs) has resulted in their dense deployment in many cities around the world. The increased interference among different WLANs severely degrades the throughput achievable. This problem has been further exacerbated by the limited number of frequency channels available. An improved distributed and dynamic channel assignment scheme that is simple to implement and does not depend on the knowledge of the throughput function is proposed in this work. It also allows each access point (AP) to asynchronously switch to the new best channel. Simulation results show that our proposed scheme converges much faster than similar previously reported work, with a reduction in convergence time and channel switches as much as 77.3% and 52.3% respectively. When it is employed in dynamic environments, the throughput improves by up to 12.7%.
Social ramifications of autonomous urban land vehicles

Autonomous vehicle technology may arrive much sooner than most people expect and it has profound implications for transportation. The technology facilitates a rail-less personal rapid transit (PRT) system using both public and private vehicles. Road traffic fatalities and injuries may decline by one to two orders of magnitude. A PRT system can provide mobility to the blind, elders suffering from dementia, children and the intoxicated. The system can make use of existing infrastructure, reduce urban sprawl and ease congestion. Autonomous vehicle based systems can improve fuel efficiency. The technology presents a window of opportunity for a new mode of transportation that obtains efficiencies of up to 0.25 l/100 km (1000 mpg equivalent), reducing U.S. petroleum consumption by up to 16%. The U.S. carbon savings could reach the equivalent of 12 trains of 100 coal cars daily.
Vulnerability to fibrillation and the ventricular-excitability curve.

P REVIOUS reports have given a description of the cyclic changes in excitability of both auricle and ventricle of the dog’s heart (I, 2). It was found that the dog’s auricle is ‘vulnerable’ to fibrillation throughout the major dip area of the excitability-recovery curve (3). A study of ventricular vulnerability has now been made. Cats and turtles were used almost exclusively in this investigation because their smaller hearts could be defibrillated more easily than the ventricle of the dog. The secondary purpose of this study was to determine whether or not the phenomena of the recovery of excitability are similar in the hearts of different vertebrates.
DEBUGGING AND MONITORING MALWARE NETWORK ACTIVITIES WITH HAKA

Malware analysts have an arsenal of tools with which to reverse engineer malware but lack the means to monitor, debug and control malicious network traffi c. In this paper we propose the use of Haka, an open source security-oriented language, to address this problem. The rationale for this is fourfold: fi rst, Haka features a grammar that allows one to naturally express malware protocol dissectors. Second, Haka provides the most advanced API for packet and stream manipulation. One can drop, create and inject packets. Haka also supports on-the-fl y packet modifi cation. For example, this enables us to hijack some botnet commands to automatically disinfect a set of compromised computers if the malware supports such C&C commands (e.g. uninstall). Third, Haka has an interactive mode that enables it to break into particular packets/streams and inspect their content. Finally, Haka provides a dedicated and customizable tool (Hakabana) to provide a real-time visualization of malware network activities through Kibana dashboards. In this paper we will a provide a set of protocol dissectors and security rules in order to monitor the C&C activities of well-known malware families and show some statistics and interesting results from our tracking of real-word C&C traffi c.
Secure scan chain using test port for tester authentication

Design-for-Test (DFT) techniques have been developed to improve testability of integrated circuits. Among the known DFT techniques, scan-based testing is considered an efficient solution for digital circuits. However, scan architecture can be exploited to wage a side channel attack. Scan chains can be used to access a cryptographic core to extract the private encryption key. There is an emerging demand for a secure scan architecture while maintaining the testability. For a scan enabled chip, if an attacker is given unlimited access to apply all sorts of inputs to the Circuit-Under-Test (CUT) and observe the outputs the probability of success increases. In this paper, a solution is presented in which, initially the CUT requests the tester to provide a secret code for authentication. The tester authentication limits the access to the scan architecture to just known testers. Moreover, in the proposed solution the number of attempts to apply test vectors and observe the results through the scan architecture is limited to make brute-force attacks practically impossible.
Reflexivity

Reflexivity, or the systematic attempt to include the spokesperson in accounts of the social world, is a magnetic signature and inherent riddle of all modern thinking about knowledge and science. Turning the narrative back upon the narrator may sharpen our critical wits about the `inescapable perspectivity' (Mannheim) of human knowledge; but self-referential accounts may also trigger endless loops of meta-theorizing and lose track of the object itself. Negotiating the twin pitfalls of spiralling meta-reflexivity and flat naturalistic accounts, I argue for a reflexive `one step up', which adds one storey to the story (no more, no less). It explores, through critical discussions of the work of Harding and Bourdieu, how reflexivity may promiscuously combine with conflicting objectivist and constructivist epistemologies, and how reflexive accounts invariably appear to run in a circle. This performative circularity, it is argued, does not invalidate the reflexive effort but defines its major strength (-in-weakness). Constitutive circularity graces both world-accounts and self-accounts with a radical uncertainty and incompleteness; which implies, among other things, that we must shift part of the burden of reflexive work to our friends, or rather: to our best enemies.
Detection and Characterization of Illegal Marketing and Promotion of Prescription Drugs on Twitter

Illicit online pharmacies allow the purchase of prescription drugs online without a prescription. Such pharmacies leverage social media platforms such as Twit- ter as a promotion and marketing tool with the intent of reaching out to a larger, potentially younger demographics of the population. Given the serious negative health effects that arise from abusing such drugs, it is important to identify the relevant content on social media and exterminate their presence as quickly as pos- sible. In response, we collected all the tweets that contained the names of certain preselected controlled substances over a period of 5 months. We found that an unsupervised topic modeling based methodology is able to identify tweets that promote and market controlled substances with high precision. We also study the meta-data characteristics of such tweets and the users who post them and find that they have several distinguishing characteristics that sets them apart. We were able to train supervised methods and achieve high performance in detecting such content and the users who post them.
239,240Pu AND INORGANIC SUBSTANCES IN AEROSOLS FROM THE VICINITY OF A WASTE ISOLATION PILOT PLANT: THE IMPORTANCE OF RESUSPENSION

Abstract— Aerosol samples were collected and analyzed to characterize the spatial and temporal variations in the concentrations of plutonium and selected inorganic substances in the atmosphere around the Waste Isolation Pilot Plant (WIPP). High-volume aerosol sampling was conducted at three sites: (1) On Site, (2) Near Field, and (3) Cactus Flats. 239,240Pu was determined by alpha spectrometry following chemical separations; mass loadings were determined gravimetrically. A separate set of low-volume aerosol samples was analyzed for major ions using ion chromatography and for trace elements by inductively-coupled plasma emission spectrometry and mass spectrometry. The average 239,240Pu activity concentrations in total suspended particle (TSP) samples (12 to 16 nBq m−3) were consistent with those previously reported, but they varied strongly with season, with the highest values generally in spring. Further, the 239,240Pu activity concentrations were comparable among the three sites, and therefore there was no evidence for elevated 239,240Pu activities due to WIPP operations. The fraction of the 239,240Pu activity concentrations in the PM10 samples (particles less than 10 &mgr;m diameter) relative to TSP was lower than the corresponding PM10/TSP ratios of either high-volume mass or several inorganics (sulfate, aluminum or lead), indicating that 239,240Pu tends to be on large particles. Aerosol mass loadings (&mgr;g m−3) and 239,240Pu activity concentrations were correlated for all sets of samples, but at On Site, the TSP samples showed higher mass to 239,240Pu ratios than the other sites. Thus activities or processes occurring at or near the WIPP site evidently produced aerosols that contributed to the mass loadings but contained less 239,240Pu than ambient aerosols. About 63% of the variability in 239,240Pu activity concentrations was explained by wind travel, sampling location, length of the sampling interval, and aerosol mass. 239,240Pu activity concentrations also were correlated with aluminum (an indicator of mineral dust), further implicating the resuspension of soils as an important determinant of 239,240Pu in aerosols. The 239,240Pu/Al ratios for the aerosols were higher than in soils, and this could be explained by the preferential binding of 239,240Pu to small soil particles that have large surface area to mass ratios and also have higher aluminum contents than larger particles.
Learning High-level Image Representation for Image Retrieval via Multi-Task DNN using Clickthrough Data

Image retrieval refers to finding relevant images from an image database for a query, which is considered difficult for the gap between low-level representation of images and high-level representation of queries. Recently further developed Deep Neural Network sheds light on automatically learning high-level image representation from raw pixels. In this paper, we proposed a multi-task DNN learned for image retrieval, which contains two parts, i.e., query-sharing layers for image representation computation and query-specific layers for relevance estimation. The weights of multi-task DNN are learned on clickthrough data by Ring Training. Experimental results on both simulated and real dataset show the effectiveness of the proposed method.
Imagerie de contraste ultrasonore avec transducteurs capacitifs micro-usinés. (Contrast agent imaging with capacitive micro-machined transducers)

Using ultrasound contrast agents, many clinical diagnoses have now been improved thanks to new contrast dedicated imaging techniques. Contrast agents are now used routinely in cardiology and in radiology to improve the detection and visualization of blood perfusion in various organs (e.g. tumors). Since a few years, Capacitive Micromachined Ultrasonic Transducers (cMUTs) have emerged as a good alternative to traditional piezoelectric transducer. cMUTs provide several advantages such as wide frequency bandwidth which could be further developed for nonlinear imaging. In this dissertation, we propose to exploit cMUT for contrast agent imaging. Firstly, the excitation signal was adapted to suppress the inherent nonlinear behavior of cMUT. Then, new detection methods based on specific acoustic properties of microbubbles have been developed and evaluated with a cMUT probe. Results show a good suppression from tissue responses whereas echoes from microbubbles are enhanced. Furthermore, the efficiency of each method is improved by the use of cMUT revealing the potential of this new transducer technology for contrast agent detection.
