Combining mobility and heterogeneous networking for emergency management: a PMIPv6 and HIP-based approach

Emergency Management is an important topic for research community worldwide, especially after recent major disasters. The problem of supporting mobility at the disaster site to rescue teams equipped with different heterogeneous access technologies and providing interoperability between different agencies and jurisdictions is still under investigation. In this work we propose to merge the advantages of IPv6 micro-mobility management of Proxy Mobile IPv6 (PMIPv6) with macro-mobility management, security, inter-technology handover and multi-homing features of Host Identity Protocol (HIP). This new approach applied to our proposed ad-hoc satellite and wireless mesh system architecture for emergency mobile communications can improve mobility, security, reliability and interoperability in Emergency Management domain.
Heart rate response during a simulated Olympic boxing match is predominantly above ventilatory threshold 2: a cross sectional study

The present study aimed to describe heart rate (HR) responses during a simulated Olympic boxing match and examine physiological parameters of boxing athletes. Ten highly trained Olympic boxing athletes (six men and four women) performed a maximal graded exercise test on a motorized treadmill to determine maximal oxygen uptake (52.2 mL · kg−1 · min−1 ± 7.2 mL · kg−1 · min−1) and ventilatory thresholds 1 and 2. Ventilatory thresholds 1 and 2 were used to classify the intensity of exercise based on respective HR during a boxing match. In addition, oxygen uptake (V̇O2) was estimated during the match based on the HR response and the HR-V̇O2 relationship obtained from a maximal graded exercise test for each participant. On a separate day, participants performed a boxing match lasting three rounds, 2 minutes each, with a 1-minute recovery period between each round, during which HR was measured. In this context, HR and V̇O2 were above ventilatory threshold 2 during 219.8 seconds ± 67.4 seconds. There was an increase in HR and V̇O2 as a function of round (round 3 < round 2 < round 1, P < 0.0001). These findings may direct individual training programs for boxing practitioners and other athletes.
Genetic Variability of Smoking Persistence in African Americans

To date, most genetic association analyses of smoking behaviors have been conducted in populations of European ancestry and many of these studies focused on the phenotype that measures smoking quantity, that is, cigarettes per day. Additional association studies in diverse populations with different linkage disequilibrium patterns and an alternate phenotype, such as total tobacco exposure which accounts for intermittent periods of smoking cessation within a larger smoking period as measured in large cardiovascular risk studies, can aid the search for variants relevant to smoking behavior. For these reasons, we undertook an association analysis by using a genotyping array that includes 2,100 genes to analyze smoking persistence in unrelated African American participants from the Atherosclerosis Risk in Communities study. A locus located approximately 4 kb downstream from the 3′-UTR of the brain-derived neurotrophic factor (BDNF) significantly influenced smoking persistence. In addition, independent variants rs12915366 and rs12914385 in the cluster of genes encoding nicotinic acetylcholine receptor subunits (CHRNA5–CHRNA3–CHRNB4) on 15q25.1 were also associated with the phenotype in this sample of African American subjects. To our knowledge, this is the first study to more extensively evaluate the genome in the African American population, as a limited number of previous studies of smoking behavior in this population included evaluations of only single genomic regions.

Mobile application for household energy consumption feedback using smart meters: Increasing energy awareness, encouraging energy savings and avoiding energy peaks

The energy consumption in form of electricity in households is highly dependent on the behavior of the inhabitants. Timely feedback on the user's household energy consumption and energy saving advisory is the key to energy saving. In this paper, the concept of a mobile application which displays real-time energy consumption information in a household is presented. The goal is to increase energy awareness amongst the users, encourage energy savings and make the user avoid using larger amounts of energy during the energy peaks. A prototype using techniques such as visualization, gamification and social networking was developed and tested in regards to its goals and usability.
Mechanical properties of styrene butadiene rubber-/ethylene propylene diene monomer rubber-based conductive blends

The mechanical properties of styrene butadiene rubber (SBR)/ethylene propylene diene monomer rubber (EPDM) conductive blends prepared by conventional mixed method were studied as a function of both blend ratio and high-abrasion furnace (HAF) carbon black (CB) contents. All measured mechanical characteristics, such as Young’s modulus, strain at break and stress at break, exhibit a transition at percolation threshold (φ c), which was found to be dependent on the SBR/EPDM blend ratio. From the dependence of the electrical conductivity of SBR, EPDM and their blends filled with HAF CB on the volume portion of the filler, the percolation concentration (φ c) was determined to be at the inflexion point φi of the dependency. The elongation at break of the investigated composites was succeeded to connect to the percolation concentration by Novak et al. model and an empirical formula suggested by us and showed reasonable results.
An evolutionary programming tool for assessing the operational value of distributed energy resources within restructured electricity industries

There is growing world-wide and Australian interest in the greater potential role of distributed generation and demand-side resources within the electricity industry. These distributed resources can offer promising economic and environmental benefits for power system operation. There are considerable challenges, however, in developing modelling tools that can explore the operational value of such resources within restructured electricity industries. This paper describes a dual evolutionary programming approach where software agents for power system resources co-evolve optimal operational behaviours over repeated power system simulations. The tool is applied to a simple case study exploring the potential operational synergies between significant PV penetrations and distributed energy storage options including controllable loads. The case study demonstrates this tool's capabilities in modelling the potentially complex operational behaviours of these distributed resources including stochastic PV outputs and loads with varying daily demand profiles, thermal energy storage, charging and discharging constraints and self-leakage.
Astrocytic clasmatodendrosis in hippocampal organ culture

Mechanisms by which astrocytes are irreversibly injured from ischemic brain injury remain incompletely defined. More than 90 years ago Alzheimer showed that astrocytes lose their distal processes (i.e., undergo “clasmatodendrosis”) when irreversibly injured by a reduction in blood flow, a process shown by Friede and van Houten ( 1961 ) to be due to energy failure and acidosis. Such alterations in astrocytic morphology can relate directly to changes in cell function. However, astrocytic clasmatodendrosis has largely been lost to the modern literature, perhaps because of a inability to study it under controlled conditions. In the present study, novel four‐dimensional (4D)and digital deblurring imaging of glial fibrillary acidic protein (GFAP) immunostaining changes in hippocampal organ cultures (HOTCs) were used to establish an in vitro model of astrocytic clasmatodendrosis. Also, astrocytes in primary culture were transfected with green fluorescent protein (GFP) to show the occurrence of clasmatodendrosis via a parallel and separate means. In HOTCs, a significant reduction in astrocytic process length occurred 15 min (and remained for 60 min) after exposure to acidic Ringer's and mitochondrial inhibition in the pyramidal cell body layer. Time‐lapsed images of primary cultures showed thinning of cell processes within 15 min of exposure to acidic Ringer's and mitochondrial inhibition. Distal processes subsequently broke away but retained their fluorescence for minutes before disintegrating along with their parent cell bodies. This report shows the spatiotemporal occurrence of clasmatodendrosis in astrocytes of HOTCs closely parallels that seen in vivo. Thus, HOTCs, where microenvironmental conditions can be controlled and single, identified cells can be followed in space and time, can be applied to study the interrelations between energy metabolism and pH that result in clasmatodendrosis.

Study of Photovoltage Decays in Nanostructured Ge/Si

Motivated by the importance of the oxidized silicon layers, we have studied the surface photovoltage (SPV) transients in nanoislands of GexSi1x on silicon and oxidized Si surfaces. It is shown that the SPV decays can be approximated by the stretched-exponential form, with the β values ranging from 0.3 to 0.6 for the islands grown on oxide-covered Si substrates and from 0.5 to 1 for the ones placed on bare Si. On this basis, a simple qualitative model is proposed that takes into account a donor-and acceptor-like interface states at the GeSi/SiO2 and Si/SiO2 interface, which act as recombination centers with densities dependent on the GeSi coverage. These results can be used to improve the functionality of photoelectric devices based on Ge/Si.
High-hydrostatic-pressure sensor using elliptical-core optical fibers

A new type of high hydrostatic pressure sensor up to 100 MPa, utilizing single-mode and two- mode elliptical-core optical fibers is presented in this paper. The sensor exploits pressure- induced effects on both fundamental and second-order modes in highly birefringent elliptical- core polarization-maintaining optical fibers. The paper discusses the principles on which the design is based, construction of the sensor in two possible configurations, instrumentation and operation, and performance under various conditions, including pressure and temperature coefficients of the output signal. In addition, pressure-induced birefringence calculated from our experiments is compared with recent theoretical results. © (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.

SST: Privacy Preserving for Semantic Trajectories

To preserve privacy in trajectory data, most existing approaches adapt cloaking techniques to protect individual location points or clustering and perturbation techniques to protect entire trajectories. To confirm to the k-anonymity model, they first group locations/trajectories and then modify location points to ensure a cluster of k location points/trajectories are close to each other. However, when k is large or the time span of trajectories is long, the cluster based k-anonymity approaches will suffer from great distortion and lead to misleading analysis results. Observing that it is unnecessary to brutally provide the same level of privacy protection to all locations, we analyze the visiting status of a semantic place at which a point is situated as well as the distribution of neighboring semantic places and infer four privacy risk levels gbased on the risk of privacy breach. Then, we propose the Semantic Space Translation (SST) algorithm that adapts different strategies accordingly to modify locations so that it can strike a good balance between privacy preserving and data utility. To verify the performance of our approach, we conduct several experiments and the experimental results show that our idea is feasible and the SST is effective.
Satisfaction With Life, Well-Being, and Meaning in Life as Protective Factors of Eating Disorder Symptoms and Body Dissatisfaction in Adolescents

This study aimed to investigate the relationship among three potential protective factors: satisfaction with life, three routes to well-being and meaning in life, and eating disorder symptoms and body dissatisfaction in male and female adolescents. The sample was composed of 247 adolescent students aged 13 to 18 years. The findings of this study support the protective roles of satisfaction with life and engagement as routes to well-being in male adolescents and particularly in female adolescents. Positive interventions to promote satisfaction with life and engagement in activities in school are highly recommended.
Definition and invariance properties of structured surface BRDF

The bidirectional reflectance distribution function (BRDF) is used to characterize the directional properties of surface reflectance, but the most recent standardized definition fails to address some important aspects for the structured and varying surfaces encountered in remote sensing. This paper proposes an updated definition of BRDF that is applicable for such surfaces. The updated definition then motivates an examination of the resulting measurement requirements and invariance properties. The conclusion is that structured surface BRDF can be defined in a consistent manner that is an intrinsic surface property, and it does exhibit the usual invariance properties associated with BRDF, such as reciprocity.
Setting time measurement using ultrasonic wave reflection

Ultrasonic shear wave reflection was used to investigate setting times of cement pastes by measuring the reflection coefficient at the interface between hydrating cement pastes of varying water-to-cement ratio and an ultrasonic buffer material. Several different buffer materials were employed, and the choice of buffer was seen to strongly affect measurement sensitivity; high impact polystyrene showed the highest sensitivity to setting processes because it had the lowest acoustic impedance value. The results show that ultrasonic shear-wave reflection can be used successfully to monitor early setting processes of cement paste with good sensitivity when such a very low impedance buffer is employed. Criteria are proposed to define set times, and the resulting initial and final set times agreed broadly with those determined using the standard penetration resistance test.
TopGen - internet router-level topology generation based on technology constraints

In order to realistically simulate algorithms or evaluate P2P overlay topologies, a detailed model of the underlying router topology is required. Since actively measuring this topology is extremely laborious and furthermore a waste of network resources, traditionally topology generators are used in order to create synthetic router-level graphs. For this, usually graph models are selected that are known to generate graphs which are similar to the actual Internet in respect to a certain metric like e.g. vertex degree distribution. These models are often superseded or adjusted when new metrics are being introduced which better differentiate between graphs. Furthermore it has been shown, that graphs that are similar in respect to e.g. vertex degree distribution can be very different from a structural point of view. In this paper Top-Gen, a generic, extensible and easy-to-use topology generation platform is presented. It contains a topology generation module which bases the generation of router-level graphs on the Internet's underlying principles and the technological constraints of routers rather than trying to effectuate similarity in respect to a certain metric. Apart from describing TopGen's general topology generation approach, graphs created with its Internet topology module are evaluated and found to be encouragingly similar to real-world datasets in various respects.
Quantitative selection of media benchmarks

Over the last decade, significant advances have been made in compilation technology and microprocessor architectures for capitalizing on instruction-level parallelism (ILP). While most of the processors containing superscalar, VLIW and SIMD structures that are well matched to the needs and capabilities of the ILP compilers are targeted at embedded applications, the majority of all ILP compilation work has been conducted in the context of general-purpose computing. As a consequence, there currently exists a gap between the compiler community and embedded application developers. We present a quantitative benchmark selection and validation technique to close the gap. It is based on more quantitatively rigorous metrics to accurately measure usefulness and effectiveness of benchmarks. We assemble a collection of DSP and communication applications written in a high-level language. An experimental selection of benchmarks from the collected applications is conducted and its applicability and usefulness are verified through an application specific system synthesis.
Three‐Dimensional Paper‐Based Model for Cardiac Ischemia

In vitro models of ischemia have not historically recapitulated the cellular interactions and gradients of molecules that occur in a 3D tissue. This work demonstrates a paper‐based 3D culture system that mimics some of the interactions that occur among populations of cells in the heart during ischemia. Multiple layers of paper containing cells, suspended in hydrogels, are stacked to form a layered 3D model of a tissue. Mass transport of oxygen and glucose into this 3D system can be modulated to induce an ischemic environment in the bottom layers of the stack. This ischemic stress induces cardiomyocytes at the bottom of the stack to secrete chemokines which subsequently trigger fibroblasts residing in adjacent layers to migrate toward the ischemic region. This work demonstrates the usefulness of patterned, stacked paper for performing in vitro mechanistic studies of cellular motility and viability within a model of the laminar ventricle tissue of the heart.

In the crystal, N—H⋯O hydrogen bonds link two cations with two anions, forming a 20-membered {⋯OCO⋯HNC3NH}2 synthon. The dimeric units are connected into a linear supramolecular chain along [100] via π–π interactions [centroid–centroid distance = 3.5625 (13) Å].
Prostate stem cell antigen-targeted nanoparticles with dual functional properties: in vivo imaging and cancer chemotherapy

Background: We designed dual-functional nanoparticles for in vivo application using a modified electrostatic and covalent layer-by-layer assembly strategy to address the challenge of assessment and treatment of hormone-refractory prostate cancer. Methods: Core-shell nanoparticles were formulated by integrating three distinct functional components, ie, a core constituted by poly(D,L-lactic-co-glycolic acid), docetaxel, and hydrophobic superparamagnetic iron oxide nanocrystals (SPIONs), a multilayer shell formed by poly(allylamine hydrochloride) and two different sized poly(ethylene glycol) molecules, and a single-chain prostate stem cell antigen antibody conjugated to the nanoparticle surface for targeted delivery. Results: Drug release profiles indicated that the dual-function nanoparticles had a sustained release pattern over 764 hours, and SPIONs could facilitate the controlled release of the drug in vitro. The nanoparticles showed increased antitumor efficiency and enhanced magnetic resonance imaging in vitro through targeted delivery of docetaxel and SPIONs to PC3M cells. Moreover, in nude mice bearing PC3M xenografts, the nanoparticles provided MRI negative contrast enhancement, as well as halting and even reversing tumor growth during the 76-day study duration, and without significant systemic toxicity. The lifespan of the mice treated with these targeted dual-function nanoparticles was significantly increased (Chi-square = 22.514, P < 0.0001). Conclusion: This dual-function nanomedical platform may be a promising candidate for tumor imaging and targeted delivery of chemotherapeutic agents in vivo.
An Assessment of the Long-Term Durability of Concrete in Radioactive Waste Repositories

A preliminary assessment of the long-term durability of concrete in a repository sited in clay is presented. The assessment is based on recorded experience of concrete structures and both field and laboratory studies. It is also supported by results of the examination of a concrete sample which had been buried in clay for 43 years. The engineering lifetime of a 1 m thick reinforced concrete slab, with one face in contact with clay, and the way in which pH in the repository as a whole is likely to vary with time have both been estimated from available data. The estimates indicate that engineering lifetimes of about 10/sup 3/ years are expected (providing that sulfate resisting cement is used) and that pH is likely to remain above 10.5 for about 10/sup 6/ years.
Childhood Trauma and COMT Genotype Interact to Increase Hippocampal Activation in Resilient Individuals

Both childhood trauma and a functional catechol-O-methyltransferase (COMT) genetic polymorphism have been associated with posttraumatic stress disorder (PTSD) and depression; however, it is still unclear whether the two interact and how this interaction relates to long-term risk or resilience. Imaging and genotype data were collected on 73 highly traumatized women. DNA extracted from saliva was used to determine COMT genotype (Val/Val, n = 38, Met carriers, n = 35). Functional MRI data were collected during a Go/NoGo task to investigate the neurocircuitry underlying response inhibition. Self-report measures of adult and childhood trauma exposure, PTSD and depression symptom severity, and resilience were collected. Childhood trauma was found to interact with COMT genotype to impact inhibition-related hippocampal activation. In Met carriers, more childhood trauma was associated with decreased hippocampal activation, whereas in the Val/Val group childhood trauma was related to increased hippocampal activation. Second, hippocampal activation correlated negatively with PTSD and depression symptoms and positively with trait resilience. Moreover, hippocampal activation mediated the relationship between childhood trauma and psychiatric risk or resilience in the Val/Val, but not in the Met carrier group. These data reveal a potential mechanism by which childhood trauma and COMT genotype interact to increase risk for trauma-related psychopathology or resilience. Hippocampal recruitment during inhibition may improve the ability to use contextual information to guide behavior, thereby enhancing resilience in trauma-exposed individuals. This finding may contribute to early identification of individuals at risk and suggests a mechanism that can be targeted in future studies aiming to prevent or limit negative outcomes.
