    This Science-Policy brief is about the influence of climate, weather and Earth's surface waters on the integration of renewables in electricity systems. It specifically refers to wind, solar and hydropower production of electricity in a future European system that is massively based on these three sources of energy. They are here named ‘Climate-Related Energies’. Following the main outcomes of the FP7 COMPLEX research project (2012-2016), this document highlights research achievements in the best interest of policy-makers, stakeholders and society, through a set of six key messages.

    Digital evidence underpin the majority of crimes as their analysis is an integral part of almost every criminal investigation. Even if we temporarily disregard the numerous challenges in the collection and analysis of digital evidence, the exchange of the evidence among the different stakeholders has many thorny issues. Of specific interest are cross-border criminal investigations as the complexity is significantly high due to the heterogeneity of legal frameworks, which beyond time bottlenecks can also become prohibiting. The aim of this article is to analyse the current state of practice of cross-border investigations considering the efficacy of current collaboration protocols along with the challenges and drawbacks to be overcome. Further to performing a legally oriented research treatise, we recall all the challenges raised in the literature and discuss them from a more practical yet global perspective. Thus, this article paves the way to enabling practitioners and stakeholders to leverage horizontal strategies to fill in the identified gaps timely and accurately.

    © 2017, Springer Science+Business Media, LLC. Heavy metals are considered some of the most toxic environmental pollutants. Exposure to heavy metals including lead (Pb), cadmium (Cd), arsenic (As), and methyl mercury (MeHg) has long been known to cause damage to human health. Many recent studies have supported the hippocampus as the major target for these four metals for inflicting cognitive dysfunction. In the present study, we proposed hippocampal relevant in vitro toxicity of Pb, Cd, As, and MeHg in HT-22 cell line. This study reports, initially, cytotoxic effects in acute, subchronic, chronic exposures. We further investigated the mechanistic potency of DNA damage and apoptosis damage with the observed cytotoxicity. The genotoxicity and apoptosis were measured by using the comet assay, annexin-V FTIC / propidium iodide (PI) assay, respectively. The results of cytotoxicity assay clearly demonstrated significant concentration and time-dependent effects on HT-22 cell line. The genotoxic and apoptosis effects also concentration-dependent fashion with respect to their potency in the range of IC 10 –IC 30, maximal level of damage observed in MeHg. In conclusion, the obtained result suggests concentration and potency-dependent response; the maximal level of toxicity was observed in MeHg. These novel findings support that Pb, Cd, As, and MeHg induce cytotoxic, genotoxic, and apoptotic effects on HT-22 cells in potency-dependent manner; MeHg> As> Cd> Pb. Therefore, the toxicity of Pb, Cd, As, and MeHg could be useful for knowing the common underlying molecular mechanism, and also for estimating the mixture impacts on HT-22 cell line.

    In this study a method for propagating the hydrological model uncertainty in discharge predictions of ungauged Mediterranean catchments using a model parameter regionalization approach is presented. The method is developed and tested for the Thau catchment located in Southern France using the SWAT hydrological model. Regionalization of model parameters, based on physical similarity measured between gauged and ungauged catchment attributes, is a popular methodology for discharge prediction in ungauged basins, but it is often confronted with an arbitrary criterion for selecting the "behavioral" model parameter sets (Mps) at the gauged catchment. A more objective method is provided in this paper where the transferrable Mps are selected based on the similarity between the donor and the receptor catchments. In addition, the method allows propagating the modeling uncertainty while transferring the Mps to the ungauged catchments. Results indicate that physically similar catchments located within the same geographic and climatic region may exhibit similar hydrological behavior and can also be affected by similar model prediction uncertainty. Furthermore, the results suggest that model prediction uncertainty at the ungauged catchment increases as the dissimilarity between the donor and the receptor catchments increases. The methodology presented in this paper can be replicated and used in regionalization of any hydrological model parameters for estimating streamflow at ungauged catchment.

    Function-as-a-Service (FaaS) has raised a growing interest in how to “tame” serverless computing to enable domain-specific use cases such as data-intensive applications and machine learning (ML), to name a few. Recently, several systems have been implemented for training ML models. Certainly, these research articles are significant steps in the correct direction. However, they do not completely answer the nagging question of when serverless ML training can be more cost-effective compared to traditional “serverful” computing. To help in this endeavor, we propose MLLESS, a FaaS-based ML training prototype built atop IBM Cloud Functions. To boost cost-efficiency, MLLESS implements two innovative optimizations tailored to the traits of serverless computing: on one hand, a significance filter, to make indirect communication more effective, and on the other hand, a scale-in auto-tuner, to reduce cost by benefiting from the FaaS sub-second billing model (often per 100 ms). Our results certify that MLLESS can be 15X faster than serverful ML systems [27] at a lower cost for sparse ML models that exhibit fast convergence such as sparse logistic regression and matrix factorization. Furthermore, our results show that MLLESS can easily scale out to increasingly large fleets of serverless workers.

    © 2018 Elsevier B.V. Behavioral targeting is a technique extensively used by the advertising industry that consists on compiling the interests of the individuals that surf the web by tracking the web sites they visit. This targeting strategy has proven to be, by far, the most effective form of advertising and, nowadays, constitutes the pillar of the Internet business model, in which free content is offered to the users in exchange for showing advertisements. Nevertheless, threatening the privacy of the people by tracking them and gathering their interests and habits is not a minor issue and, in recent years, many users have reacted by installing tools in their browsers that block all connections suspicious of being advertisements. By blocking indiscriminately and systematically, these tools protect the privacy of their users, but also hamper the online advertising business and, hence, endanger the sustainability of the ‘free’ Internet model. To tackle this issue, we propose a system that conciliates users’ privacy during web surfing and the advertising business. Specifically, our proposal empowers the user in the protection of her privacy by allowing her to define her privacy requirements, that is, which user's interests should be hidden from the advertising platforms and which ones can be revealed. Then, our system selectively blocks or bypasses tracking on the browsed web sites according to their content and the privacy requirements. Our system is also the first that implements simulated browsing sessions as a privacy-preserving measure. Empirical results show that our proposal allows fine grained and user tailored privacy protection, which is also more accurate, responsive and respectful with the Internet business model than related works.

    This study used a novel integrated technology of ceramic supported carbon membrane(CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneouslyas biofilm support, redox mediator, and nano-filter to enhance the dye decolorization efficiency. Thedecolorization of Acid Orange 7 (AO7) was initially investigated with and without microorganismsin both ceramic support (CS) and CSCM reactors. The CSCM bioreactor (B-CSCM), operated withmicroorganisms, gave a maximum decolorization of 98% using a CSCM evolved from 10% weight(wt.) of Matrimid 5218 solution. To know the influence of permeate flow, feed concentration, anddye structure on the decolorization process, different B-CSCMs for dye removal experiments werestudied over monoazo AO7, diazo Reactive Black 5 (RB5), and triazo Direct Blue 71 (DB71). Thehighest color removal, operated with 50 mg·L-1feed solution and 0.05 L·m-2·h-1of permeate flux,was 98%, 82%, and 72%, respectively, for AO7, RB5, and DB71. By increasing these parameters to100 mg·L-1and 0.1 L·m-2·h-1, the decolorization rate of dye solution still achieved 37% for AO7,30% for RB5, and 26% for DB71. In addition, the system was run for weeks without apparent loss ofactivity. These findings make evident that the combined phenomena taking place in CSCM bioreactorresult in an efficient, cost-effective, and ecofriendly azo dye decolorization method.

    This Science-Policy brief is about the influence of climate, weather and Earth's surface waters on the integration of renewables in electricity systems. It specifically refers to wind, solar and hydropower production of electricity in a future European system that is massively based on these three sources of energy. They are here named ‘Climate-Related Energies’. Following the main outcomes of the FP7 COMPLEX research project (2012-2016), this document highlights research achievements in the best interest of policy-makers, stakeholders and society, through a set of six key messages.

    Digital evidence underpin the majority of crimes as their analysis is an integral part of almost every criminal investigation. Even if we temporarily disregard the numerous challenges in the collection and analysis of digital evidence, the exchange of the evidence among the different stakeholders has many thorny issues. Of specific interest are cross-border criminal investigations as the complexity is significantly high due to the heterogeneity of legal frameworks, which beyond time bottlenecks can also become prohibiting. The aim of this article is to analyse the current state of practice of cross-border investigations considering the efficacy of current collaboration protocols along with the challenges and drawbacks to be overcome. Further to performing a legally oriented research treatise, we recall all the challenges raised in the literature and discuss them from a more practical yet global perspective. Thus, this article paves the way to enabling practitioners and stakeholders to leverage horizontal strategies to fill in the identified gaps timely and accurately.

    © 2017, Springer Science+Business Media, LLC. Heavy metals are considered some of the most toxic environmental pollutants. Exposure to heavy metals including lead (Pb), cadmium (Cd), arsenic (As), and methyl mercury (MeHg) has long been known to cause damage to human health. Many recent studies have supported the hippocampus as the major target for these four metals for inflicting cognitive dysfunction. In the present study, we proposed hippocampal relevant in vitro toxicity of Pb, Cd, As, and MeHg in HT-22 cell line. This study reports, initially, cytotoxic effects in acute, subchronic, chronic exposures. We further investigated the mechanistic potency of DNA damage and apoptosis damage with the observed cytotoxicity. The genotoxicity and apoptosis were measured by using the comet assay, annexin-V FTIC / propidium iodide (PI) assay, respectively. The results of cytotoxicity assay clearly demonstrated significant concentration and time-dependent effects on HT-22 cell line. The genotoxic and apoptosis effects also concentration-dependent fashion with respect to their potency in the range of IC 10 –IC 30, maximal level of damage observed in MeHg. In conclusion, the obtained result suggests concentration and potency-dependent response; the maximal level of toxicity was observed in MeHg. These novel findings support that Pb, Cd, As, and MeHg induce cytotoxic, genotoxic, and apoptotic effects on HT-22 cells in potency-dependent manner; MeHg> As> Cd> Pb. Therefore, the toxicity of Pb, Cd, As, and MeHg could be useful for knowing the common underlying molecular mechanism, and also for estimating the mixture impacts on HT-22 cell line.

    In this study a method for propagating the hydrological model uncertainty in discharge predictions of ungauged Mediterranean catchments using a model parameter regionalization approach is presented. The method is developed and tested for the Thau catchment located in Southern France using the SWAT hydrological model. Regionalization of model parameters, based on physical similarity measured between gauged and ungauged catchment attributes, is a popular methodology for discharge prediction in ungauged basins, but it is often confronted with an arbitrary criterion for selecting the "behavioral" model parameter sets (Mps) at the gauged catchment. A more objective method is provided in this paper where the transferrable Mps are selected based on the similarity between the donor and the receptor catchments. In addition, the method allows propagating the modeling uncertainty while transferring the Mps to the ungauged catchments. Results indicate that physically similar catchments located within the same geographic and climatic region may exhibit similar hydrological behavior and can also be affected by similar model prediction uncertainty. Furthermore, the results suggest that model prediction uncertainty at the ungauged catchment increases as the dissimilarity between the donor and the receptor catchments increases. The methodology presented in this paper can be replicated and used in regionalization of any hydrological model parameters for estimating streamflow at ungauged catchment.

    Function-as-a-Service (FaaS) has raised a growing interest in how to “tame” serverless computing to enable domain-specific use cases such as data-intensive applications and machine learning (ML), to name a few. Recently, several systems have been implemented for training ML models. Certainly, these research articles are significant steps in the correct direction. However, they do not completely answer the nagging question of when serverless ML training can be more cost-effective compared to traditional “serverful” computing. To help in this endeavor, we propose MLLESS, a FaaS-based ML training prototype built atop IBM Cloud Functions. To boost cost-efficiency, MLLESS implements two innovative optimizations tailored to the traits of serverless computing: on one hand, a significance filter, to make indirect communication more effective, and on the other hand, a scale-in auto-tuner, to reduce cost by benefiting from the FaaS sub-second billing model (often per 100 ms). Our results certify that MLLESS can be 15X faster than serverful ML systems [27] at a lower cost for sparse ML models that exhibit fast convergence such as sparse logistic regression and matrix factorization. Furthermore, our results show that MLLESS can easily scale out to increasingly large fleets of serverless workers.

    © 2018 Elsevier B.V. Behavioral targeting is a technique extensively used by the advertising industry that consists on compiling the interests of the individuals that surf the web by tracking the web sites they visit. This targeting strategy has proven to be, by far, the most effective form of advertising and, nowadays, constitutes the pillar of the Internet business model, in which free content is offered to the users in exchange for showing advertisements. Nevertheless, threatening the privacy of the people by tracking them and gathering their interests and habits is not a minor issue and, in recent years, many users have reacted by installing tools in their browsers that block all connections suspicious of being advertisements. By blocking indiscriminately and systematically, these tools protect the privacy of their users, but also hamper the online advertising business and, hence, endanger the sustainability of the ‘free’ Internet model. To tackle this issue, we propose a system that conciliates users’ privacy during web surfing and the advertising business. Specifically, our proposal empowers the user in the protection of her privacy by allowing her to define her privacy requirements, that is, which user's interests should be hidden from the advertising platforms and which ones can be revealed. Then, our system selectively blocks or bypasses tracking on the browsed web sites according to their content and the privacy requirements. Our system is also the first that implements simulated browsing sessions as a privacy-preserving measure. Empirical results show that our proposal allows fine grained and user tailored privacy protection, which is also more accurate, responsive and respectful with the Internet business model than related works.

    This study used a novel integrated technology of ceramic supported carbon membrane(CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneouslyas biofilm support, redox mediator, and nano-filter to enhance the dye decolorization efficiency. Thedecolorization of Acid Orange 7 (AO7) was initially investigated with and without microorganismsin both ceramic support (CS) and CSCM reactors. The CSCM bioreactor (B-CSCM), operated withmicroorganisms, gave a maximum decolorization of 98% using a CSCM evolved from 10% weight(wt.) of Matrimid 5218 solution. To know the influence of permeate flow, feed concentration, anddye structure on the decolorization process, different B-CSCMs for dye removal experiments werestudied over monoazo AO7, diazo Reactive Black 5 (RB5), and triazo Direct Blue 71 (DB71). Thehighest color removal, operated with 50 mg·L-1feed solution and 0.05 L·m-2·h-1of permeate flux,was 98%, 82%, and 72%, respectively, for AO7, RB5, and DB71. By increasing these parameters to100 mg·L-1and 0.1 L·m-2·h-1, the decolorization rate of dye solution still achieved 37% for AO7,30% for RB5, and 26% for DB71. In addition, the system was run for weeks without apparent loss ofactivity. These findings make evident that the combined phenomena taking place in CSCM bioreactorresult in an efficient, cost-effective, and ecofriendly azo dye decolorization method.
