MOSAR: A Secure On-demand Routing Protocol for Mobile Multilevel Ad Hoc Networks

In this paper, we propose a routing scheme, called MOSAR, which is able to handle the security classiﬁ-cation of packets during the route discovery and route maintenance. The scheme should provide the network reasonable balances between security, performance and computation power eﬃciency. For above purposes, a new ﬁeld called Route Security Requirement is added in the routing header as the indicator of security requirement. Therefore, routing is about to ﬁnd the path from source to destination that all the nodes on which meet the security requirement. Besides, to protect routing packets against unauthorized disclosure, modiﬁcation or eavesdropping, the protocol oﬀers diﬀerent cryptographic mechanisms that are scalable to the computation resources at each Trust level for authentication and integrity check, and if necessary, packet secrecy. Our goal is to design a dependable and aﬀordable routing protocol for ad hoc networks where the security requirements are diﬀerent for diﬀerent information to transmit, under diﬀerent circumstances, or with diﬀerent available resources. Through the simulations, we can conclude that MOSAR functions well in handling classiﬁcation and it can perform better than the regular AODV protocol.
Microstrip Bandpass Filters With Various Resonators Using Connected- and Edge-Coupling Mechanisms and Their Applications to Dual-Band Filters and Diplexers

Microstrip bandpass filters designed with various types of transmission-line resonators are newly proposed in this study. The connected-coupling mechanisms are theoretically analyzed and then appropriately applied in the design of an all-connected-coupling basic filter for preliminary validation. With the simultaneous utilization of conventional edge-coupling and the proposed connected-coupling mechanisms, a fifth-order stopband-extended filter with half- and quarter-wave resonators is then accomplished based on resonance misalignment. After that, the newly proposed three-way resonators made possible by the proposed coupling schemes have been employed as the frequency-selective power-splitting/combing elements for design of dual-band filters and diplexers. Specifically, in the constructed dual-band filter, the three-way resonators not only serve as a power splitter/combiner, but also play the important role of resonant components among filters. As for the presented diplexer, the three-way resonator splits the signal to two channels without necessitating extra matching circuits and thereby economizes the occupied area. The proposed approaches have been validated by experimental results that are well predicted by simulations.
Mixed-Initiative in Computer Games : Algorithmic Content Creation in Open-ended Worlds

We provide a general definition of mixed-initiative for application to the area of computer games. This definition is used to provide a survey of the ways in which mixedinitiative has been applied to games up to this point, and where and how mixed-initiative could be applied to improve the quality of games in the future. The need for algorithmic content creation though mixed-initiative interactions is demonstrated, and the application of mixed-initiative interactions to the challenge of developing realistic interactions with computer-controlled agents in an openended role-playing game is analyzed.

The assessment of alcoholism in surveys of the general community: What are we measuring? Some insights from the Australian twin panel interview survey

The majority of cases identified by commonly used alcoholism criteria in general community surveys are mild ones, with few alcohol-related problems. We illustrate this using data on 2088 Australian male twins aged 28–89 (mean age = 42.7), including 1846 who reported more than minimal alcohol exposure when surveyed by telephone in 1992–3. Using latent class analysis of alcoholism symptoms reported by these twins, we identify five classes of respondent: those with no alcohol-related problems (49% of the sample, if we include those with minimal alcohol exposure); excessive drinkers (33%); and individuals with a history of mild (14%), moderate (3%) or severe problems (1%). Symptom endorsement profiles associated with these different classes are illustrated. The two most severe classes constitute a substantial majority of those reporting alcoholism treatment, but a minority of those reporting alcohol-related auto accidents or injuries, recurrent hazardous alcohol use, or alcohol-related arrests. The excessive .
The Clustering of Intergalactic Metals

We measure the spatial clustering of metals in the intergalactic medium (IGM) from z = 1.7 to 3.0, as traced by 643 C IV and 104 Si IV N ≥ 1012 cm-2 absorption systems in 19 high signal-to-noise ratio (40-80) and high-resolution (R = 45,000) quasar spectra. The number densities and two-point correlation functions of both these species are largely constant with redshift, suggesting that the bulk of metal ejection occurred at z ≥ 3. However, at z ≤ 1.9, some additional signature appears in the C IV correlation function at 500 km s-1, associated with four strong and peculiar systems. At all redshifts, the C IV and Si IV correlation functions exhibit a steep rise at large separations and a flatter profile at small separations, with an elbow occurring at ~150 km s-1. We show that these properties are consistent with metals confined within bubbles with a typical radius Rs about sources of mass ≥Ms, and we use numerical simulations to derive best-fit values of Rs ~ 2 comoving Mpc and Ms ~ 5 × 1011 M☉ at z = 3. This does not exclude the possiblity that metals could have been produced at higher redshifts in smaller, but equally rare, objects. At the level of detection of this survey, IGM enrichment is likely to be incomplete and inhomogeneous, with a filling factor of ~10%.
Parallel Fibers Synchronize Spontaneous Activity in Cerebellar Golgi Cells

Cerebellar Golgi cells inhibit their afferent interneurons, the excitatory granule cells. Such a feedback inhibition causes both inhibitory and excitatory neurons in the circuit to synchronize. Our modeling work predicts that the long granule cell axons, the parallel fibers, entrain many Golgi cells and their afferent granule cells in a single synchronous rhythm. Spontaneous activity of 42 pairs of putative Golgi cells was recorded in anesthetized rats to test these predictions. In 25 of 26 pairs of Golgi cells that were positioned along the transverse axis, and presumed to receive common parallel fiber input, spontaneous activity showed a high level of coherence (mean Z score > 6). Conversely, 12 of 16 Golgi cell pairs positioned along the parasagittal axis (no common parallel fiber input) were not synchronized; 4 of 16 of them showed only low levels of synchronicity (mean Z score < 4). For transverse pairs the accuracy of the coherence, measured as the width at half-height of the central peak of the cross-correlogram, was rather low (29.8 +/- 12.5 msec) but increased with Golgi cell firing rate, as predicted by the model. These results suggest that in addition to their role as gain controllers, cerebellar Golgi cells may control the timing of granule cell spiking.
Voxelwise nonlinear regression toolbox for neuroimage analysis: Application to aging and neurodegenerative disease modeling

We illustrate its features using a relevant example in which distinct nonlinear trajectories of Alzheimer's disease related brain atrophy patterns were found across the full biological spectrum of the disease. The open-source toolbox presented in this paper is available at this https URL.
Optimization in the private value model: competitive analysis applied to auction design

We consider the study of a class of optimization problems with applications towards profit maximization. One feature of the classical treatment of optimization problems is that the space over which the optimization is being performed, i.e., the input description of the problem, is assumed to be publicly known to the optimizer. This assumption does not always accurately represent the situation in practical applications. Recently, with the advent of the Internet as one of the most important arenas for resource sharing between parties with diverse and selfish interests, this distinction has become more readily apparent. The inputs to many optimizations being performed are not publicly known in advance. Instead they must be solicited from companies, computerized agents, individuals, etc., that may act selfishly to promote their own self-interests. In particular, they may lie about their values or may not adhere to specified protocols if it benefits them. An auction is one of the simplest applications where the classical (a.k.a. public value) optimization approach fails to work as expected in the presence of selfish agents with private data. We consider casting profit optimization problems into the game theoretic framework of mechanism design and consider the design of auction mechanisms to maximize the profit of the auctioneer. We show how a competitive analysis can be used to gauge the performance of profit maximizing mechanisms. We develop a number of techniques for designing auctions and show how they can be extended to more complex profit maximization problems.
Wave-Like Solutions of General 1-D Spatially Coupled Systems

We establish the existence of wave-like solutions to spatially coupled graphical models which, in the large size limit, can be characterized by a 1-D real-valued state. This is extended to a proof of the threshold saturation phenomenon for all such models, which includes spatially coupled irregular low-density parity-check codes over the binary erasure channel (BEC), but also addresses hard-decision decoding for transmission over general channels, the code division multiple access problem, compressed sensing, and some statistical physics models. For traditional uncoupled iterative coding systems with two components and transmission over the BEC, the asymptotic convergence behavior is completely characterized by the EXIT curves of the components. In particular, the system converges to the desired fixed point, which is the one corresponding to perfect decoding, if and only if the two EXIT functions describing the components do not cross. For spatially coupled systems whose state is 1-D a closely related graphical criterion applies. Now the curves are allowed to cross, but not by too much. More precisely, we show that the threshold saturation phenomenon is related to the positivity of the (signed) area enclosed by two EXIT-like functions associated to the component systems, a very intuitive, and easy-to-use graphical characterization. In the spirit of EXIT functions and Gaussian approximations, we also show how to apply the technique to higher dimensional and even infinite-dimensional cases. In these scenarios, the method is no longer rigorous, but it typically gives accurate predictions. To demonstrate this application, we discuss transmission over general channels using both the belief-propagation as well as the min-sum decoder.
Dynamical evolution of globular cluster systems in clusters of galaxies: I. The case of NGC 1404 in the Fornax cluster

We investigate, via numerical simulations, the tidal stripping and accretion of globular clusters (GCs). In particular, we focus on creating models that simulate the situation for the GC systems of NGC 1404 and NGC 1399 in the Fornax cluster, which have poor (specific frequency SN � 2) and rich (SN � 10) GC systems respectively. We initially assign NGC 1404 in our simulation a typical SN (� 5) for cluster ellipticals, and find that its GC system can only be reduced through stripping to the presently observed value, if its orbit is highly eccentric (with orbital eccentricity of > 0.5) and if the initial scale length of the GCs system is about twice as large as the effective radius of NGC 1404 itself. These stripped GCs can be said to have formed a ‘tidal stream’ of intracluster globular clusters (ICGCs) orbiting the centre of Fornax cluster (many of which would be assigned to NGC 1399 in an imaging study). The physical properties of these GCs (e.g., number, radial distribution, and kinematics) depend on the orbit and initial distribution of GCs in NGC 1404. Our simulations also predict a trend for SN to rise with increasing clustercentric distance - a trend for which there is some observational support in the Fornax cluster. We demonstrate that since the kinematical properties of ICGCs formed by tidal stripping in the cluster tidal field depend strongly on the orbits of their previous host galaxies, observations of ICGC kinematics provides a new method for probing galaxy dynamics in a cluster.
Nomophobia - mobile phone dependence, a study among students of a rural medical college

Background: Nomophobia literally means ‘no mobile phobia’ that is the fear of being out of mobile phone contact. People experience symptoms of withdrawal when they are away from mobile phones.

Now a day’s nomophobia is an alarming issue and it should be addressed on priority basis.
WiMsh: a simple and efficient tool for simulating IEEE 802.16 wireless mesh networks in ns-2

Wireless mesh networks (WMNs) are two-tier wireless multihop networks. The top tier is made of wireless routers, which provide access to the wireless clients in the bottom tier. One technology for enabling multi-hop communication in the top tier is IEEE 802.16, which includes a mesh mode, in addition to the Point-to-Multipoint mode for cellular networks. As is often the case with wireless networks, simulation is often employed as the primary means of investigation. There are several network simulation tools, both commercial and free-of-charge, with IEEE 802.16 PMP support. However, the MAC protocol designed for mesh mode is substantially different from that for PMP operation, which creates the need for a specific simulation tool. In this paper we describe a simulation module, called WiMsh, than enables simulation of IEEE 802.16 wireless mesh networks with the popular Network Simulator 2. We have made publicly available WiMsh in October 2007 as open source software.
Minimal structures for stories

Our research on Interactive Drama aims at conciliating interaction and story at the deepest level, the level of action. From a given story representation formalism, a set of elementary narrative structures is derived in order to capture the minimal requirements for providing a narrative and interactive experience to a user. Some of these structures are implemented and simulated, to illustrate the quality and limitations of each structure.
Quantification of Cellular NEMO Content and Its Impact on NF-κB Activation by Genotoxic Stress

NF-κB essential modulator, NEMO, plays a key role in canonical NF-κB signaling induced by a variety of stimuli, including cytokines and genotoxic agents. To dissect the different biochemical and functional roles of NEMO in NF-κB signaling, various mutant forms of NEMO have been previously analyzed. However, transient or stable overexpression of wild-type NEMO can significantly inhibit NF-κB activation, thereby confounding the analysis of NEMO mutant phenotypes. What levels of NEMO overexpression lead to such an artifact and what levels are tolerated with no significant impact on NEMO function in NF-κB activation are currently unknown. Here we purified full-length recombinant human NEMO protein and used it as a standard to quantify the average number of NEMO molecules per cell in a 1.3E2 NEMO-deficient murine pre-B cell clone stably reconstituted with full-length human NEMO (C5). We determined that the C5 cell clone has an average of 4 x 105 molecules of NEMO per cell. Stable reconstitution of 1.3E2 cells with different numbers of NEMO molecules per cell has demonstrated that a 10-fold range of NEMO expression (0.6–6x105 molecules per cell) yields statistically equivalent NF-κB activation in response to the DNA damaging agent etoposide. Using the C5 cell line, we also quantified the number of NEMO molecules per cell in several commonly employed human cell lines. These results establish baseline numbers of endogenous NEMO per cell and highlight surprisingly normal functionality of NEMO in the DNA damage pathway over a wide range of expression levels that can provide a guideline for future NEMO reconstitution studies.
Accuracy and reproducibility of left ventricular outflow tract diameter measurement using transthoracic when compared with transesophageal echocardiography in systole and diastole.

AIMS Accurate measurement of left ventricular outflow tract diameter (LVOTd) is essential for reliable estimation of aortic valve area (AVA) using the continuity equation. Transesophageal echocardiography (TEE) can accurately delineate the LVOT. The aim of this study was to assess the accuracy and reproducibility of LVOTd measurement using transthoracic echocardiography (TTE) with harmonic imaging when compared with TEE, in both systole and diastole. METHODS AND RESULTS We prospectively studied 50 patients [20 with aortic stenosis (AS) and 30 without AS]. LVOTd was measured offline in a blinded fashion in both systole and diastole by two experienced observers using TTE in the parasternal long axis view and TEE in the mid-oesophageal aortic view ( approximately 130 degrees ). There was strong correlation between TTE and TEE (r=0.91). LVOTd was slightly smaller by TTE when compared with TEE (2.11+/-0.21 vs. 2.16+/-0.22 cm, mean difference -0.05+/-0.09 cm, P=0.0003). Compared with TEE, 95% (2SD) of LVOTd measurements by TTE were within +0.14 and -0.24 cm. Inter- and intra-observer variability for LVOTd was 4.8+/-4.1 and 2.8+/-1.9% for TTE and 4.2+/-3.1 and 2.5+/-1.6% for TEE (P=0.4 and 0.6). In patients with AS, estimated AVA was 0.93+/-0.22 cm(2) using TTE and 0.96+/-0.24 cm(2) using TEE, P=0.08. Diastolic LVOTd by TEE was slightly smaller compared with systolic LVOTd by TEE (-0.03+/-0.07 cm, P=0.0005), and there was strong correlation between the two (r=0.95). CONCLUSION We present the data regarding accuracy and reproducibility of LVOTd measurements by TTE when compared with TEE. LVOTd measurements at end-diastole may be helpful when systolic images are suboptimal.
The Value of Higher Education: Individual and Societal Benefits

An absorption refrigerator of natural circulation type employing water as a refrigerant and lithium salt as an absorbing medium, in which a U-tube is disposed in a conduit portion between a condenser and an evaporator and is connected at one end thereof to a separator in addition to the condenser and at the other end thereof to a refrigerant reservoir. A cooling conduit extends into this refrigerant reservoir to maintain substantially constant the internal pressure of the reservoir so that the amount of the refrigerant stored in the reservoir can be controlled depending on the pressure difference between the separator side of the U-tube and the reservoir side of the U-tube. Therefore, the concentration of the lithium salt solution circulating through the refrigeration system can be controlled depending on the temperature of a heating medium supplied to a generator.

Dominant resonant mode damping of a piezoelectric tube nanopositioner using optimal sensorless shunts

Piezoelectric tube scanners are used in most commercial scanning probe microscopes, to provide precise motion to the scanning tip. Due to their mechanical construction, they have a relatively low-frequency first resonant mode. This mode gets excited due to environmental noise and introduces errors in the scan obtained. In precision scanning applications, this limits the upper bound of a triangular scan rate to around 1/100th the first mechanical resonance frequency. Feedback control techniques and shunt damping methods have shown promising results in damping this resonant mode and improving scan performance. Most of these techniques need a sensor, which in turn adds complexity to the overall system. With this motivation, passive sensorless shunt damping has been investigated and documented. In this work, we design active sensorless shunts, optimized using H2 and Hinfin techniques. These shunts damp the modal amplitude of the first resonant peak by almost 24 dB. A triangle raster pattern used to test the scan accuracy shows significant improvement due to the damping achieved by these active shunts.
