Published: March 2016

AbstractTwo acyclic cucurbit[n]uril (CB[n])‐type molecular containers that differ in the length of the (CH2)n linker (M2C2: n=2, M2C4: n=4) between their aromatic sidewalls and sulfonate solubilizing groups were prepared and studied. The inherent solubilities of M2C2 (68 mm) and M2C4 (196 mm) are higher than the analogue with a (CH2)3 linker (M2, 14 mm) studied previously. 1H NMR dilution experiments show that M2C2 and M2C4 do not self‐associate in water, which enables their use as solubilizing excipients. We used phase solubility diagrams (PSDs) to compare the solubilizing capacities of M2, M2C2, M2C4, hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD), and sulfobutylether‐β‐cyclodextrin (SBE‐β‐CD) toward 15 insoluble drugs. We found that M2C2 and M2C4—as gauged by the slope of their PSDs—are less potent solubilizing agents than M2. However, the higher inherent solubility of M2C2 allows higher concentrations of drug to be formulated using M2C2 than with M2 in several cases. The solubilizing ability of M2C2 and SBE‐β‐CD were similar in many cases, with Krel values averaging 23 and 12, respectively, relative to HP‐β‐CD. In vitro cytotoxicity and in vivo maximum tolerated dose studies document the biocompatibility of M2C2.
The study of the function of AQP4 in cerebral ischaemia–reperfusion injury using poroelastic theory
Authors: Mokhtarudin Mohd Jamil Mohamed , Payne Stephen J. 
Published: March 2016

SummaryBrain oedema is thought to form and to clear through the use of water‐protein channels, aquaporin‐4 (AQP4), which are found in the astrocyte endfeet. The model developed here is used to study the function of AQP4 in the formation and elimination of oedema fluid in ischaemia–reperfusion injury. The cerebral space is assumed to be made of four fluid compartments: astrocyte, neuron, ECS and blood microvessels, and a solid matrix for the tissue, and this is modelled using multiple‐network poroelastic theory. AQP4 allows the movement of water between astrocyte and the ECS and the microvessels. It is found that the presence of AQP4 may help in reducing vasogenic oedema shown by a decrease in brain tissue extracellular pressure. However, the astrocyte pressure will increase to compensate for this decrease, which may lead to cytotoxic oedema. In addition, the swelling will also depend on the ionic concentrations in the astrocyte and extracellular space, which may change after ischaemic stroke. Understanding the role of AQP4 in oedema may thus help the development of a treatment plan in reducing brain swelling after ischaemia–reperfusion
HTC‐Sim: a trace‐driven simulation framework for energy consumption in high‐throughput computing systems
Authors: Forshaw M. , McGough A.S. , Thomas N. 
Published: March 2016

SummaryHigh‐throughput computing (HTC) is a powerful paradigm allowing vast quantities of independent work to be performed simultaneously across many loosely coupled computers. These systems often exploit the idle time available on computers provisioned for other purposes – volunteer computing. However, until recently, little evaluation has been performed on the energy impact of HTC. Many organisations now seek to minimise energy consumption across their IT infrastructure. However, it is unclear how this will affect the usability of HTC systems especially when exploiting volunteer computers. We present here HTC‐Sim, a simulation system that allows the evaluation of different energy reduction policies across an HTC system. We model systems that comprised both collections of computational resources dedicated to HTC work and resources provided through volunteer computing – a desktop grid. We demonstrate that our simulation software scales linearly with increasing HTC workload. We go further to evaluate a number of resource selection policies in terms of the overheads/slowdown incurred and the energy impact on the HTC system. Copyright © 2016 John Wiley & Sons, Ltd.
Supporting efficient execution of continuous space agent‐based simulation on GPU
Authors: Li Xiaosong , Cai Wentong , Turner Stephen John 
Published: March 2016

SummaryUsing agent‐based simulation (ABS) to analyze complex adaptive systems gains growing popularity over the past decades. One of the fundamental issues in ABS is to increase the execution speed. In this paper, we identify two common modules that widely exist in ABS applications, namely, the agent management module and the agent interaction module. Improving the efficiency of these two common modules can significantly speed up the ABS execution in general. GPU architecture, programming model, and memory hierarchy are studied. Effective strategies on GPU are proposed when we design the two modules. The first contribution of this work is to propose an AgentPool data structure to handle agent creation and deletion on GPU. The second contribution is an efficient agent interaction module, which is designed by carefully utilizing the GPU memory hierarchy. To demonstrate effectiveness and generality, the proposed strategies are applied to a range of ABS applications, including game‐of‐life, flocking boids, prey‐and‐predator, and the social force‐based crowd simulation. The simulation results demonstrate that the proposed strategies achieve better performance than the commonly used CPU and GPU ABS framework, namely, Mason and FLAME, for ABS applications using continuous space.

A Thermally‐Regenerative Ammonia‐Based Flow Battery for Electrical Energy Recovery from Waste Heat
Authors: Zhu Xiuping , Rahimi Mohammad , Gorski Christopher A. , Logan Bruce 
Published: March 2016

AbstractLarge amounts of low‐grade waste heat (temperatures <130 °C) are released during many industrial, geothermal, and solar‐based processes. Using thermally‐regenerative ammonia solutions, low‐grade thermal energy can be converted to electricity in battery systems. To improve reactor efficiency, a compact, ammonia‐based flow battery (AFB) was developed and tested at different solution concentrations, flow rates, cell pairs, and circuit connections. The AFB achieved a maximum power density of 45 W m−2 (15 kW m−3) and an energy density of 1260 Wh manolyte−3, with a thermal energy efficiency of 0.7 % (5 % relative to the Carnot efficiency). The power and energy densities of the AFB were greater than those previously reported for thermoelectrochemical and salinity‐gradient technologies, and the voltage or current could be increased using stacked cells. These results demonstrated that an ammonia‐based flow battery is a promising technology to convert low‐grade thermal energy to electricity.

Published: March 2016

AbstractWe report the fabrication of a carbon‐based high energy density Li‐ion hybrid electrochemical capacitor (Li‐HEC) from low cost and eco‐friendly materials. High surface area (2448±20 m2 g−1) activated carbon (AC) is derived from the environmentally threatening plant, Prosopis juliflora, and used as the positive electrode in a Li‐HEC assembly. Natural graphite is employed as negative electrode and electrochemically pre‐lithiated prior to the Li‐HEC fabrication. The Li‐HEC delivers a specific energy of 162.3 Wh kg−1 and exhibits excellent cyclability (i.e., ∼79 % of initial capacity is retained after 7000 cycles). The superior electrochemical performance of Li‐HEC benefits from the tube‐like unique structural features of the AC. Also, the presence of a graphitic nanocarbon network improves the ion transport, and the formed micro‐ and meso‐porous network acts as reservoir for the accommodation of charge carriers.

AbstractA composite of g‐C3N4 with visible‐light photoactive S‐doped carbon was synthesized. Synergistic effects in surface chemistry and electrical conductivity, and a decrease in the band gap (Eg, estimated from optical measurements) from 2.91 eV for g‐C3N4 to 2.79 eV for the composite were found. Both the carbon and the composite showed photosensitivity but only the composite revealed a visible‐light‐driven reduction activity.
Efficient Regular Perovskite Solar Cells Based on Pristine [70]Fullerene as Electron‐Selective Contact

Published: March 2016

Abstract[70]Fullerene is presented as an efficient alternative electron‐selective contact (ESC) for regular‐architecture perovskite solar cells (PSCs). A smart and simple, well‐described solution processing protocol for the preparation of [70]‐ and [60]fullerene‐based solar cells, namely the fullerene saturation approach (FSA), allowed us to obtain similar power conversion efficiencies for both fullerene materials (i.e., 10.4 and 11.4 % for [70]‐ and [60]fullerene‐based devices, respectively). Importantly, despite the low electron mobility and significant visible‐light absorption of [70]fullerene, the presented protocol allows the employment of [70]fullerene as an efficient ESC. The [70]fullerene film thickness and its solubility in the perovskite processing solutions are crucial parameters, which can be controlled by the use of this simple solution processing protocol. The damage to the [70]fullerene film through dissolution during the perovskite deposition is avoided through the saturation of the perovskite processing solution with [70]fullerene. Additionally, this fullerene‐saturation strategy improves the performance of the perovskite film significantly and enhances the power conversion efficiency of solar cells based on different ESCs (i.e., [60]fullerene, [70]fullerene, and TiO2). Therefore, this universal solution processing protocol widens the opportunities for the further development of PSCs.
Condition‐dependent ejaculate production affects male mating behavior in the common bedbugCimex lectularius
Authors: Kaldun Bettina , Otti Oliver 
Published: March 2016

AbstractFood availability in the environment is often low and variable, constraining organisms in their resource allocation to different life‐history traits. For example, variation in food availability is likely to induce condition‐dependent investment in reproduction. Further, diet has been shown to affect ejaculate size, composition and quality. How these effects translate into male reproductive success or change male mating behavior is still largely unknown. Here, we concentrated on the effect of meal size on ejaculate production, male reproductive success and mating behavior in the common bedbugCimex lectularius. We analyzed the production of sperm and seminal fluid within three different feeding regimes in six different populations. Males receiving large meals produced significantly more sperm and seminal fluid than males receiving small meals or no meals at all. While such condition‐dependent ejaculate production did not affect the number of offspring produced after a single mating, food‐restricted males could perform significantly fewer matings than fully fed males. Therefore, in a multiple mating context food‐restricted males paid a fitness cost and might have to adjust their mating strategy according to the ejaculate available to them. Our results indicate that meal size has no direct effect on ejaculate quality, but food availability forces a condition‐dependent mating rate on males. Environmental variation translating into variation in male reproductive traits reveals that natural selection can interact with sexual selection and shape reproductive traits. As males can modulate their ejaculate size depending on the mating situation, future studies are needed to elucidate whether environmental variation affecting the amount of ejaculate available might induce different mating strategies.
Short lasting transient effects of a capsaicin 8% patch on nociceptor activation in humans

Published: March 2016

AbstractBackgroundAt high concentration, the TRPV‐1 agonist capsaicin de‐sensitizes nociceptors and reduces the intra‐epidermal nerve density.MethodsWe investigated the effects of a 5 × 10 cm capsaicin 8% patch on C‐ and A‐delta‐nociceptor activation in ten healthy subjects before and at days 1–3–7–21 after patch application. Thermal thresholds, infrared thulium‐YAG laser‐evoked potentials (LEP) and heat pain (numeric rating scale, NRS, 0–10), electrically induced pain (10 pulses, 1.5‐fold pain threshold intensity, five randomized series of 5–10–20–50–100 Hz), and axon‐reflex flare (laser Doppler imaging) were recorded.ResultsThermal hypoesthesia developed upon capsaicin 8% treatment. Warmth detection thresholds increased at day 1–3, heat pain thresholds were increased by about 2.6 °C after day 3, and laser‐evoked heat pain remained significantly reduced for 7 days. Axon‐reflex flare responses (days 1–3), but not supra‐threshold electrically induced pain were significantly reduced by the capsaicin patch.ConclusionsAxonal nociceptor function assessed by electrical excitability tests supplements threshold tests of nociceptive endings. The differential analgesic effects of 8% capsaicin patches may be attributed to the kinetics of capsaicin and the different depth of nociceptive nerve fibres, yet, the time course does not match the long‐lasting analgesia observed in neuropathic pain patients treated with the same patch.What does this study add?Axonal nociceptor function assessed by supra‐threshold electrical excitability tests did not coincide with capsaicin‐induced transduction changes supplementing threshold measures of terminal nociceptor endings.Threshold measurements do not reflect the sustained effect of pain relief seen in neuropathic pain patients.Capsaicin‐sensitive nociceptors responsible for spontaneous pain are either not specifically tested with currently available sensory stimulation protocols or have higher capsaicin sensitivity or slower recovery under neuropathic conditions.
Probabilistic seismic demand model for pounding risk assessment
Authors: Tubaldi Enrico , Freddi Fabio , Barbato Michele 
Published: March 2016

SummaryEarthquake‐induced pounding of adjacent structures can cause severe structural damage, and advanced probabilistic approaches are needed to obtain a reliable estimate of the risk of impact. This study aims to develop an efficient and accurate probabilistic seismic demand model (PSDM) for pounding risk assessment between adjacent buildings, which is suitable for use within modern performance‐based engineering frameworks. In developing a PSDM, different choices can be made regarding the intensity measures (IMs) to be used, the record selection, the analysis technique applied for estimating the system response at increasing IM levels, and the model to be employed for describing the response statistics given the IM. In the present paper, some of these choices are analyzed and evaluated first by performing an extensive parametric study for the adjacent buildings modeled as linear single‐degree‐of‐freedom systems, and successively by considering more complex nonlinear multi‐degree‐of‐freedom building models. An efficient and accurate PSDM is defined using advanced intensity measures and a bilinear regression model for the response samples obtained by cloud analysis. The results of the study demonstrate that the proposed PSDM allows accurate estimates of the risk of pounding to be obtained while limiting the number of simulations required.
