Local food web management increases resilience and buffers against global change effects on freshwaters
Authors: Urrutia-Cordero Pablo , Ekvall Mattias K. , Hansson Lars-Anders
Published: July 2016

A major challenge for ecological research is to identify ways to improve resilience to climate-induced changes in order to secure the ecosystem functions of natural systems, as well as ecosystem services for human welfare. With respect to aquatic ecosystems, interactions between climate warming and the elevated runoff of humic substances (brownification) may strongly affect ecosystem functions and services. However, we hitherto lack the adaptive management tools needed to counteract such global-scale effects on freshwater ecosystems. Here we show, both experimentally and using monitoring data, that predicted climatic warming and brownification will reduce freshwater quality by exacerbating cyanobacterial growth and toxin levels. Furthermore, in a model based on long-term data from a natural system, we demonstrate that food web management has the potential to increase the resilience of freshwater systems against the growth of harmful cyanobacteria and thereby that local efforts offer an opportunity to secure our water resources against some of the negative impacts of climate warming and brownification. This allows for novel policy action at a local scale to counteract effects of global-scale environmental change, thereby providing a buffer period and a safer operating space until climate mitigation strategies are effectively established.
Investigating the dynamics of surface-immobilized DNA nanomachines
Authors: Dunn Katherine E. , Trefzer Martin A. , Johnson Steven , Tyrrell Andy M.
Published: July 2016

Surface-immobilization of molecules can have a profound influence on their structure, function and dynamics. Toehold-mediated strand displacement is often used in solution to drive synthetic nanomachines made from DNA, but the effects of surface-immobilization on the mechanism and kinetics of this reaction have not yet been fully elucidated. Here we show that the kinetics of strand displacement in surface-immobilized nanomachines are significantly different to those of the solution phase reaction and we attribute this to the effects of intermolecular interactions within the DNA layer. We demonstrate that the dynamics of strand displacement can be manipulated by changing strand length, concentration and G/C content. By inserting mismatched bases it is also possible to tune the rates of the constituent displacement processes (toehold-binding and branch migration) independently and information can be encoded in the time-dependence of the overall reaction. Our findings will facilitate the rational design of surface-immobilized dynamic DNA nanomachines, including computing devices and track-based motors.

Published: July 2016

Fibroblast growth factor-21 (FGF21) is closely related to various metabolic and cardiovascular disorders. However, the direct targets and mechanisms linking FGF21 to blood pressure control and hypertension are still elusive. Here we demonstrated a novel regulatory function of FGF21 in the baroreflex afferent pathway (the nucleus tractus solitarii, NTS; nodose ganglion, NG). As the critical co-receptor of FGF21, β-klotho (klb) significantly expressed on the NTS and NG. Furthermore, we evaluated the beneficial effects of chronic intraperitoneal infusion of recombinant human FGF21 (rhFGF21) on the dysregulated systolic blood pressure, cardiac parameters, baroreflex sensitivity (BRS) and hyperinsulinemia in the high fructose-drinking (HFD) rats. The BRS up-regulation is associated with Akt-eNOS-NO signaling activation in the NTS and NG induced by acute intravenous rhFGF21 administration in HFD and control rats. Moreover, the expressions of FGF21 receptors were aberrantly down-regulated in HFD rats. In addition, the up-regulated peroxisome proliferator-activated receptor-γ and -α (PPAR-γ/-α) in the NTS and NG in HFD rats were markedly reversed by chronic rhFGF21 infusion. Our study extends the work of the FGF21 actions on the neurocontrol of blood pressure regulations through baroreflex afferent pathway in HFD rats.
A noise model for the evaluation of defect states in solar cells
Authors: Landi G. , Barone C. , Mauro C. , Neitzert H. C. , Pagano S.
Published: July 2016

A theoretical model, combining trapping/detrapping and recombination mechanisms, is formulated to explain the origin of random current fluctuations in silicon-based solar cells. In this framework, the comparison between dark and photo-induced noise allows the determination of important electronic parameters of the defect states. A detailed analysis of the electric noise, at different temperatures and for different illumination levels, is reported for crystalline silicon-based solar cells, in the pristine form and after artificial degradation with high energy protons. The evolution of the dominating defect properties is studied through noise spectroscopy.

Published: July 2016

Atomic resolution scanning transmission electron microscopy and electron energy loss spectroscopy combined with ab initio electronic calculations are used to determine the structure and properties of the Fe3O4(111)/SrTiO3(111) polar interface. The interfacial structure and chemical composition are shown to be atomically sharp and of an octahedral Fe/SrO3 nature. Band alignment across the interface pins the Fermi level in the vicinity of the conduction band of SrTiO3. Density functional theory calculations demonstrate very high spin-polarization of Fe3O4 in the interface vicinity which suggests that this system may be an excellent candidate for spintronic applications.

Published: July 2016

Bacteria-based living anticancer agents have emerged as promising therapeutics. However, the functional role of autophagy in bacterial cancer therapy has been little investigated. In this study, Salmonella VNP20009 induced autophagy in B16F10 cells, which is an unfavorable factor in bacterial cancer therapy. Inhibiting the induction of autophagy by chloroquine or siRNA in bacterial cancer therapy dose- and time-dependently promoted cell death. The combined therapy of VNP20009 and chloroquine not only enhanced the bacterial tumor targeting ability but also facilitated the infiltration of immune cells into the tumor. Our results showed that the combined therapy of VNP20009 and chloroquine could significantly inhibit tumor growth and prolong mouse survival time. This study provides a novel strategy for improving the anti-cancer efficacy of bacterial cancer therapy.
Men increase contributions to a public good when under sexual competition
Authors: Tognetti Arnaud , Dubois Dimitri , Faurie Charlotte , Willinger Marc
Published: July 2016

Why humans cooperate in large groups and with non-kin remains a puzzle for researchers across the natural and social sciences. Investigating whether cooperation is sexually selected could contribute to an understanding of the evolution of human cooperation. Competition for access to mates could indeed select for cooperation. Using controlled laboratory experiments, we analyse whether and how the sex composition of a social environment, testosterone level and relationship status affect contributions to a public good. The results show that variation in sex composition alters the amount of money that single men (but not men in a couple or women) contribute to a public good. Notably, in line with the competitive helping hypothesis, awareness of the presence of a woman leads to larger contributions by single men, most likely by triggering their competitiveness to be the most cooperative man in the group. However, we find no link between basal testosterone level and cooperativeness. We argue that men, notably single men, adopt cooperative behaviours as a signalling strategy in the context of mate choice and hence that cooperation is partly sexually selected. Our findings highlight the need to consider sexual selection as an additional mechanism for cooperation.
AP-1/σ1A and AP-1/σ1B adaptor-proteins differentially regulate neuronal early endosome maturation via the Rab5/Vps34-pathway
Authors: Candiello Ermes , Kratzke Manuel , Wenzel Dirk , Cassel Dan , Schu Peter
Published: July 2016

The σ1 subunit of the AP-1 clathrin-coated-vesicle adaptor-protein complex is expressed as three isoforms. Tissues express σ1A and one of the σ1B and σ1C isoforms. Brain is the tissue with the highest σ1A and σ1B expression. σ1B-deficiency leads to severe mental retardation, accumulation of early endosomes in synapses and fewer synaptic vesicles, whose recycling is slowed down. AP-1/σ1A and AP-1/σ1B regulate maturation of these early endosomes into multivesicular body late endosomes, thereby controlling synaptic vesicle protein transport into a degradative pathway. σ1A binds ArfGAP1 and with higher affinity brain-specific ArfGAP1, which bind Rabex-5. AP-1/σ1A-ArfGAP1-Rabex-5 complex formation leads to more endosomal Rabex-5 and enhanced, Rab5GTP-stimulated Vps34 PI3-kinase activity, which is essential for multivesicular body endosome formation. Formation of AP-1/σ1A-ArfGAP1-Rabex-5 complexes is prevented by σ1B binding of Rabex-5 and the amount of endosomal Rabex-5 is reduced. AP-1 complexes differentially regulate endosome maturation and coordinate protein recycling and degradation, revealing a novel molecular mechanism by which they regulate protein transport besides their established function in clathrin-coated-vesicle formation.

Interleukin-18 deficiency protects against renal interstitial fibrosis in aldosterone/salt-treated mice
Authors: Tanino Akiko , Okura Takafumi , Nagao Tomoaki , Kukida Masayoshi , Pei Zuowei , Enomoto Daijiro , Miyoshi Ken-ichi , Okamura Haruki , Higaki Jitsuo
Published: July 2016

Interleukin (IL)-18 is a member of the IL-1 family of cytokines and was described originally as an interferon γ-inducing factor. Aldosterone plays a central role in the regulation of sodium and potassium homoeostasis by binding to the mineralocorticoid receptor and contributes to kidney and cardiovascular damage. Aldosterone has been reported to induce IL-18, resulting in cardiac fibrosis with induced IL-18-mediated osteopontin (OPN). We therefore hypothesized that aldosterone-induced renal fibrosis via OPN may be mediated by IL-18. To verify this hypothesis, we compared mice deficient in IL-18 and wild-type (WT) mice in a model of aldosterone/salt-induced hypertension. IL-18−/− and C57BL/6 WT mice were used for the uninephrectomized aldosterone/salt hypertensive model, whereas NRK-52E cells (rat kidney epithelial cells) were used in an in vitro model. In the present in vivo study, IL-18 protein expression was localized in medullary tubules in the WT mice, whereas in aldosterone-infused WT mice this expression was up-regulated markedly in the proximal tubules, especially in injured and dilated tubules. This renal damage caused by aldosterone was attenuated significantly by IL-18 knockout with down-regulation of OPN expression. In the present in vitro study, aldosterone directly induced IL-18 gene expression in renal tubular epithelial cells in a concentration- and time-dependent manner. These effects were inhibited completely by spironolactone. IL-18 may be a key mediator of aldosterone-induced renal fibrosis by inducing OPN, thereby exacerbating renal interstitial fibrosis. Inhibition of IL-18 may therefore provide a potential target for therapeutic intervention aimed at preventing the progression of renal injury.
Epigenetic regulation of TGF-β1 signalling in dilative aortopathy of the thoracic ascending aorta

The term ‘epigenetics’ refers to heritable, reversible DNA or histone modifications that affect gene expression without modifying the DNA sequence. Epigenetic modulation of gene expression also includes the RNA interference mechanism. Epigenetic regulation of gene expression is fundamental during development and throughout life, also playing a central role in disease progression. The transforming growth factor β1 (TGF-β1) and its downstream effectors are key players in tissue repair and fibrosis, extracellular matrix remodelling, inflammation, cell proliferation and migration. TGF-β1 can also induce cell switch in epithelial-to-mesenchymal transition, leading to myofibroblast transdifferentiation. Cellular pathways triggered by TGF-β1 in thoracic ascending aorta dilatation have relevant roles to play in remodelling of the vascular wall by virtue of their association with monogenic syndromes that implicate an aortic aneurysm, including Loeys–Dietz and Marfan's syndromes. Several studies and reviews have focused on the progression of aneurysms in the abdominal aorta, but research efforts are now increasingly being focused on pathogenic mechanisms of thoracic ascending aorta dilatation. The present review summarizes the most recent findings concerning the epigenetic regulation of effectors of TGF-β1 pathways, triggered by sporadic dilative aortopathy of the thoracic ascending aorta in the presence of a tricuspid or bicuspid aortic valve, a congenital malformation occurring in 0.5–2% of the general population. A more in-depth comprehension of the epigenetic alterations associated with TGF-β1 canonical and non-canonical pathways in dilatation of the ascending aorta could be helpful to clarify its pathogenesis, identify early potential biomarkers of disease, and, possibly, develop preventive and therapeutic strategies.
Event‐triggered output tracking control for wireless networked control systems with communication delays and data dropouts
Authors: Peng Chen , Song Yang , Peng Xie Xiang , Zhao Min , Fei Mei‐Rui
Published: July 2016

This study addresses the event‐triggered output tracking control under wireless network environments. First, an improved event‐triggered communication scheme and a sampled‐state‐error dependent tracking model for wireless networked control systems is presented. In this scheme and model, (a) the sensor takes samples in a periodic manner; (b) an improved event‐triggering condition is applied in the communications to determine whether the sampled data is transmitted to the controller or not; and (c) the closed‐loop tracking system with a networked state‐dependent controller is modelled as an augmented time‐delay system. Second, by constructing a novel Lyapunov–Krasovskii functional, two theorems are derived with guaranteed H∞ tracking performance subject to imperfect wireless communications. The tracking performance is based on two permissible limits on the signal transmission. That is, the maximum allowable communication delay bound and maximum allowable number of successive data dropouts. Finally, a satellite tracking example is given to show the effectiveness of the proposed method.

Authors: Menezes Eduardo F.M. , Aguiar Raquel S.S. , Simões Alberto M. , Apkarian Pierre
Published: July 2016

A new μ synthesis technique is presented that allows the design of controllers satisfying prescribed structural constraints as well as robust against mixed uncertainties. Such features are rarely jointly present in existing methods. The proposed approach relies on a numerically efficient non‐smooth optimisation algorithm to obtain locally optimal solutions. The validity of the new synthesis technique is corroborated by a challenging case study in which the objective is to design a structured controller for the uncertain flexible model of a rocket in upper atmosphere flight.
Transient measured impedance‐based protection scheme for DC line faults in ultra high‐voltage direct‐current system
Authors: Liu Jian , Tai Nengling , Fan Chunju , Yang Yayu
Published: July 2016

DC line fault is a major threat to the security of ultra high‐voltage direct‐current system due to complex terrain and terrible weather conditions over long distances. This study proposes a DC line backup protection method on the basis of transient measured impedance (TMI), which is defined as the ratio of transient voltage and transient current at both sides of DC line. The characteristics of TMIs are theoretically analysed for DC line faults and external faults, and these characteristics are used to construct a protection scheme. Since the TMIs only depend on the system structure, the proposed method is able to identify the faults correctly, unaffected by the fault resistance and DC line attenuation. A selection method for the faulted line is also proposed based on the ratio of transient component on the bipolar lines. Comparison with the transient‐component‐based protections and conventional protections demonstrates the promising performance of the proposed protection. Numerous simulations on PSCAD/EMTDC platform and the tests with field fault‐recording data have validated the effectiveness of the proposed protection scheme.
Physical understanding of gas-liquid annular flow and its transition to dispersed droplets
Authors: Kumar Parmod , Das Arup Kumar , Mitra Sushanta K.
Published: July 2016

Transformation from annular to droplet flow is investigated for co-current, upward gas-liquid flow through a cylindrical tube using grid based volume of fluid framework. Three transitional routes, namely, orificing, rolling, and undercutting are observed for flow transformation at different range of relative velocities between the fluids. Physics behind these three exclusive phenomena is described using circulation patterns of gaseous phase in the vicinity of a liquid film which subsequently sheds drop leading towards transition. Orifice amplitude is found to grow exponentially towards the core whereas it propagates in axial direction in a parabolic path. Efforts have been made to fit the sinusoidal profile of wave structure with the numerical interface contour at early stages of orificing. Domination of gas inertia over liquid flow has been studied in detail at the later stages to understand the asymmetric shape of orifice, leading towards lamella formation and droplet generation. Away from comparative velocities, circulations in the dominant phase dislodge the drop by forming either a ligament (rolling) or a bag (undercut) like protrusion in liquid. Study of velocity patterns in the plane of droplet dislodge reveals the underlying physics behind the disintegration and its dynamics at the later stages. Using numerical phase distributions, rejoining of dislodged droplet with liquid film as post-rolling consequences has been also proposed. A flow pattern map showing the transitional boundaries based on the physical mechanism is constructed for air-water combination.
The optimal home energy management strategy in smart grid
Authors: Zhou Yimin
Published: July 2016

In this paper, an optimal appliance management strategy proposed is participated in by both energy suppliers and customers. Through mathematical description of the appliance operation, a suitable plan is derived to satisfy both the power limits requested from the power suppliers and the least electricity bills from the end-users. Furthermore, the power suppliers will monitor the behaviours of the energy requirement from the customers. When the demanded electricity is close to the limits, the supplier will send a feedback signal to ask the end-users to stop using some kinds of appliances or postpone their operation for a while. When the demand is too low, a signal will also be sent to the end-users from the supplier to remind that some flexible appliances can be activated or used in order to achieve the “peak load shifting.” Renewable energy is also taken into account in the distribution network as auxiliary energy suppliers. Simulation experiments have been performed to prove the effectiveness of the proposed strategy.
Forest fire break not a barrier to movement for a threatened rodent, the smoky mouse, Pseudomys fumeus (Rodentia : Muridae)
Authors: Macak P. V. , Menkhorst P. W.
Published: July 2016

Linear clearings associated with roads passing through vegetation communities are known to inhibit movements of many animal species. This can reduce breeding, dispersal and foraging opportunities and lead to population fragmentation, putting further pressure on populations that are small or vulnerable, such as those of threatened species. We tested the prediction that the threatened smoky mouse, Pseudomys fumeus, would not readily cross a 30-m-wide fire break constructed along a ridgeline in eucalypt forest in Victoria, south-eastern Australia. Radio-tracking was conducted along 650 m of the fire break from October to December 2011. We recorded seven individuals that crossed the break. Five individuals fitted with transmitter collars were detected crossing at least twice on 13 of 18 tracking nights. Two animals were found to have crossed by being tracked to nests during the day and/or via trapping. A nearby narrow, unsealed vehicle track was crossed by an additional animal. Our results suggest that it is unlikely that the fire break was acting as a barrier to P. fumeus movements. The presence of fire breaks in P. fumeus habitat may, however, expose individuals to a higher rate of predation when they cross large areas unprotected by vegetation cover.
The coordination of moves in Aikido interaction
Authors: Lefebvre Augustin
Published: July 2016

Relying on the analysis of naturally occurring interaction recordings, this article proposes the moment-by-moment description of a specific type of focused interaction, the interaction of the martial art Aikido. In Aikido encounters, participants exchange moves of attack, defense, avoidance also using a “weapon”. These “Aikido movements”, as I shall call them, are articulated by the whole body and serve as projectable interactional units. Aikido movements appear as highly ordered minimal units of the practitioners’ activity which are coordinated between them in space and time. Central in this account is the description of the interactional space elaborated through the moving transactional segments of the practitioners. I suggest that the description of the visible bodily actions of Aikido opens a range of questions concerning the social and interactional construction of human perception in any activity involving whole body movements. As visible actions, Aikido movement and gesture share the property of becoming units of the social activity they organize.
Waste to worth: vegetable wastes as animal feed.

Published: July 2016

The chemical composition, nutritional value and use of a number of vegetable wastes (VWs) and by-products such as baby corn, cabbage, carrot, cauliflower, cucumber, jackfruit, peas, potato, sweet corn (SC), tomato, and radish leaves, among others in ruminant and monogastric diets, are presented in this publication. These products are rich in both protein and energy. Bottle gourd pulp, cabbage leaves, pea pods (PP), potato vines, pumpkin oil meal, radish leaves, snow peas, sugar beet leaves and tomato pomace have around or more than 20% crude protein (CP). The remaining VWs contain 10-19% CP, except carrot pulp, jackfruit waste, SC husk, SC cob and SC husk
plus
cob, which have less than 10% CP. Most of these wastes have high acceptability and palatability, and products such as sarson saag waste and PP supplemented with mineral mixture and common salt can be fed
ad libitum
to the livestock as complete feed. The major constraints in using these products as livestock feed are their high moisture content and presence of contaminants, mainly pesticides and pesticide residues. Drying and ensiling have been used for enhancing shelf life and making their incorporation in animal feeds easier. There is a need to monitor pesticide and pesticide residues, mycotoxins, heavy metals and antinutritional factors before using vegetable products in animal diets. Full potential of these unconventional feed resources can be realized by concerted commercial efforts. These resources are yet untapped and their efficient use will enlarge feed resource base, enhance feed availability and bring the wasted food back to human food chain.

Published: July 2016

Although omics datasets represent valuable assets for hypothesis generation, model testing, and data validation, the infrastructure supporting their reuse lacks organization and consistency. Using nuclear receptor signaling transcriptomic datasets as proof of principle, we developed a model to improve the discoverability, accessibility, and citability of published omics datasets. Primary datasets were retrieved from archives, processed to extract data points, then subjected to metadata enrichment and gap filling. The resulting secondary datasets were exposed on responsive web pages to support mining of gene lists, discovery of related datasets, and single-click citation integration with popular reference managers. Automated processes were established to embed digital object identifier-driven links to the secondary datasets in associated journal articles, small molecule and gene-centric databases, and a dataset search engine. Our model creates multiple points of access to reprocessed and reannotated derivative datasets across the digital biomedical research ecosystem, promoting their visibility and usability across disparate research communities.
