Forensic Intelligence and the Deportation Research Clinic: Toward a New Paradigm
Authors: Stevens Jacqueline
Published: September 2015

Since 2012, the Deportation Research Clinic, part of the Buffett Institute for Global Studies at Northwestern University, has been pursuing research on government misconduct under the rubric of what Jacqueline Stevens calls “forensic intelligence.” The Clinic uses law and publicity, including scholarship, to create new realities, which in turn produce new facts and knowledge. Stevens draws on scholarship by S.M. Amadae, Noam Chomsky, Philip Green, Chalmers Johnson, Kenneth Osgood, Ido Oren, Michael Rogin, and Frances Saunders to explain the relation of “forensic intelligence” to the “national intelligence” paradigm now organizing mainstream political science research. The article concludes by describing how U.S. government and economic elites distort research and teaching priorities, and provides examples from Northwestern University.
A discussion of Alexander S. Kirschner's A Theory
of Militant Democracy: The Ethics of Combatting Political Extremism
Authors: Capoccia Giovanni
Published: September 2015

The legitimacy claims of liberal democratic states are typically couched in the
language of individual rights and the rule of law. But contemporary liberal
democratic states increasingly appeal to a logic of security, law and order, and
the need to combat “political extremism.” This logic plays
out in Ukraine, Egypt, and Turkey, and in Greece and Germany, but also in the
U.S., France, and the UK. It is an increasingly important feature of politics in
societies that may be experiencing a rough “transition to
democracy,” but also in societies that are conventionally regarded as
“consolidated democracies.” The normative and practical
challenges presented by this situation are fundamental. Alexander S.
Kirschner’s A Theory of Militant Democracy: The Ethics of Combatting
Political Extremism offers one interesting take on these issues, which cut to
the core of political science as a discipline. We have thus invited a range of
political scientists from a variety of subfield and methodological perspectives
to comment on the book and on the broader topic the book engages—the
ethics of combatting political extremism and indeed the very political
construction of “political extremism.” -- Jeffrey C.

Authors: Boncinelli Fabio , Bartolini Fabio , Brunori Gianluca , Casini Leonardo
Published: September 2015

Support for organic farming is a key strategy of rural development policies in several countries. This paper studied the spatial pattern of participation in agro-environmnetal policy the policies designing to foster diffusion of organic farming. The ultimate goal is to investigate the impact of local factors for improving the policy targeting. Indicators of spatial association and a spatial econometrics model were performed for the analysis. The results show regional agglomeration effects of the rate of participants to the measures adopted to promote organic farming. In addition, a spatial relation among the farms that obtain public support is found, highlighting that the diffusion of participation is driven mainly by imitation process and external economies of scale.

Published: September 2015

Stemborers are a major constraint to the production of rice in the Kou Valley, Burkina Faso. Biological control is a good alternative to the use of agrochemicals that are harmful to human and animal health, and the environment. A survey of natural enemies of stemborers was conducted during the 2014 rice-cropping season across three transplanting periods (P1, P2 and P3). Plant and insect samples were collected by mowing and trapping at weekly intervals until harvest, starting 21 days after transplanting, and examined microscopically. Immature stages of the parasitized stemborers were reared to maturity for a positive identification of the parasitoids. Three genera of stemborers were identified:Chilo(Lepidoptera: Pyralidae),Maliarpha(Lepidoptera: Pyralidae) andSesamia(Lepidoptera: Noctuidae). TheChilogenus was the most important with an average percentage of 41.4% of the pre-imaginal population in P2 followed byMarliarpha(1.1%) andSesamia(0%). A total of 15 hymenopteran parasitoid species that included nine genera and seven families were identified. All the parasitoids were associated withChiloand only two of the species parasitizedMaliarpha. The most frequent parasitoids encountered wereBracon testacerofatus,Goniozus indicus,Dolichogenidea oryzaeandBraconspp. A total of 28 predator species were recorded from 22 genera, 6 orders and 15 families.Leucaugesp.,Agriocnemissp.,Lycosa pseudoannulataandLycosasp. were the most important predators with frequencies reaching 15% of the arthropods caught in some fields. These results will be employed to develop a sustainable system to manage rice stemborers.

Published: September 2015

Temperature has a fundamental impact on the metabolic rates of microorganisms and strongly influences microbial ecology and biogeochemical cycling in the environment. In this study, we examined the catabolic temperature response of natural communities of sulfate-reducing microorganisms (SRM) in polar, temperate and tropical marine sediments. In short-term sediment incubation experiments with 35S-sulfate, we demonstrated how the cardinal temperatures for sulfate reduction correlate with mean annual sediment temperatures, indicating specific thermal adaptations of the dominant SRM in each of the investigated ecosystems. The community structure of putative SRM in the sediments, as revealed by pyrosequencing of bacterial 16S rRNA gene amplicons and phylogenetic assignment to known SRM taxa, consistently correlated with in situ temperatures, but not with sediment organic carbon concentrations or C:N ratios of organic matter. Additionally, several species-level SRM phylotypes of the class Deltaproteobacteria tended to co-occur at sites with similar mean annual temperatures, regardless of geographic distance. The observed temperature adaptations of SRM imply that environmental temperature is a major controlling variable for physiological selection and ecological and evolutionary differentiation of microbial communities.
FOXO1 inhibits osteosarcoma oncogenesis via Wnt/β-catenin pathway suppression
Authors: Guan H , Tan P , Xie L , Mi B , Fang Z , Li J , Yue J , Liao H , Li F
Published: September 2015

Recent advances have highlighted profound roles of FOXO transcription factors, especially FOXO1, in bone development and remodeling. The regulation of bone development by FOXOs seems to be stage-specific or context dependent. FOXOs promote maintenance and differentiation of early progenitors of the osteoblast lineage and repress proliferation of committed osteoblast precursors; FOXO1 is vital for osteocyte survival. Considering the versatile roles played by FOXOs in bone development and tumorigenesis, it is plausible that FOXO1, the main FOXO in bone with a non-redundant role, might have influence on osteosarcoma (OS) oncogenesis. Indeed, recent results have implicated that FOXO1 has a tumor-suppressing role in OS. In the present study, we found thatFOXO1expression was generally low or absent in OS, with a minority of cases having moderate expression. Whole-genome sequencing (WGS) revealed that theFOXO1locus was frequently involved in copy number variation and loss of heterozygosity in OS, indicating that chromosomal aberrations might be partially responsible for the heterogeneity inFOXO1expression. FOXO1 activation in OS cell lines inhibited cancer cell survival, which can be attributed to modulation of target genes, includingBIMand repressed Wnt/β-catenin signaling. FOXO1 inhibition promoted cell proliferation, enhanced colony formation and attenuated osteogenic differentiation of OS cell lines. To conclude, our results proved FOXO1 as a tumor suppressor in OS at least partially by suppression of the Wnt/β-catenin pathway.
Optimal nonlinear information processing capacity in delay-based reservoir computers
Authors: Grigoryeva Lyudmila , Henriques Julie , Larger Laurent , Ortega Juan-Pablo
Published: September 2015

Reservoir computing is a recently introduced brain-inspired machine learning paradigm capable of excellent performances in the processing of empirical data. We focus in a particular kind of time-delay based reservoir computers that have been physically implemented using optical and electronic systems and have shown unprecedented data processing rates. Reservoir computing is well-known for the ease of the associated training scheme but also for the problematic sensitivity of its performance to architecture parameters. This article addresses the reservoir design problem, which remains the biggest challenge in the applicability of this information processing scheme. More specifically, we use the information available regarding the optimal reservoir working regimes to construct a functional link between the reservoir parameters and its performance. This function is used to explore various properties of the device and to choose the optimal reservoir architecture, thus replacing the tedious and time consuming parameter scannings used so far in the literature.
Accumulation of organic C components in soil and aggregates
Authors: Yu Hongyan , Ding Weixin , Chen Zengming , Zhang Huanjun , Luo Jiafa , Bolan Nanthi
Published: September 2015

To explore soil organic carbon (SOC) accumulation mechanisms, the dynamics of C functional groups and macroaggregation were studied synchronously through aggregate fractionation and 13C NMR spectroscopy in sandy loam soil following an 18-year application of compost and fertilizer in China. Compared with no fertilizer control, both compost and fertilizer improved SOC content, while the application of compost increased macroaggregation. Fertilizer application mainly increased the levels of recalcitrant organic C components characterized by methoxyl/N-alkyl C and alkyl C, whereas compost application mainly promoted the accumulation of methoxyl/N-alkyl C, phenolic C, carboxyl C, O-alkyl C and di-O-alkyl C in bulk soil. The preferential accumulation of organic C functional groups in aggregates depended on aggregate size rather than nutrient amendments. These groups were characterized by phenolic C and di-O-alkyl C in the silt + clay fraction, carboxyl C in microaggregates and phenolic C, carboxyl C and methoxyl/N-alkyl C in macroaggregates. Thus, the differences in accumulated organic C components in compost- and fertilizer-amended soils were primarily attributable to macroaggregation. The accumulation of methoxyl/N-alkyl C in microaggregates effectively promoted macroaggregation. Our results suggest that organic amendment rich in methoxyl/N-alkyl C effectively improved SOC content and accelerated macroaggregation in the test soil.
Long-Range Ruthenium-Amine Electronic Communication through the para-Oligophenylene Wire
Authors: Shen Jun-Jian , Zhong Yu-Wu
Published: September 2015

The studies of long-range electronic communication are hampered by solubility and potential-splitting issues. A “hybridized redox-asymmetry” method using a combination of organic and inorganic redox species is proposed and exemplified to overcome these two issues. Complexes 1(PF6)–6(PF6) (from short to long in length) with the organic redox-active amine and inorganic cyclometalated ruthenium termini bridged by the para-oligophenylene wire have been prepared. Complex 6 has the longest Ru-amine geometrical distance of 27.85 Å. Complexes 3(PF6) and 4(PF6) show lamellar crystal packing on the basis of a head-to-tail anti-parallelly aligned dimeric structure. Two redox waves are observed for all complexes in the potential region between +0.2 and +0.9 V vs Ag/AgCl. The electrochemical potential splitting is 410, 220, 143, 112, 107 and 105 mV for 1(PF6) through 6(PF6), respectively. Ruthenium (+2) to aminium (N•+) charge transfer transitions have been identified for the odd-electron compounds 12+–62+ by spectroelectrochemical measurements. The electronic communication between amine and ruthenium decreases exponentially with a decay slope of −0.137 Å−1. DFT calculations have been performed to complement these experimental results.
Young dispersal of xerophil Nitraria lineages in intercontinental disjunctions of the Old World
Authors: Zhang Ming-Li , Temirbayeva Kamshat , Sanderson Stewart C. , Chen Xi
Published: September 2015

Many cases of intercontinental disjunct distributions of seed plants have been investigated, however few have concerned the continents of Eurasia (mainly Central Asia), Africa and Australia, especially the xerophytic lineages are lacking. Nitraria (Nitrariaceae) is just one of these xerophytic lineages. Previous Nitraria studies have hypothesized either Africa as the ancient center, with dispersals to Australia and Eurasia, or alternatively Central Asia, due to a concentration of endemism and diversity there. Our findings show eastern Central Asia, i.e. the eastern Tethys, to be the correct place of origin. Dispersal westward to Africa occurred during the late Oligocene to Pliocene, whereas dispersal to Australia from western Central Asia was young since Pliocene 2.61 Ma. Two related tetraploids are indicated to have diversified in eastern Central Asia at approximately 5.89 Ma, while the Australian tetraploid N. billardieri, is an independently derived, recent dispersal from western Central Asia.

Published: September 2015

We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus (ABPV). Peptide alignments revealed detection of complete structural DWV-complex block VP2-VP1-VP3, VDV-1 helicase and single-amino-acid substitution A/K/Q in VP1, the ABPV structural block VP1-VP4-VP2-VP3 including uncleaved VP4/VP2 and VdMLV coat protein. Isoforms of viral structural proteins of highest abundance were localized via 2D-E. The presence of all types of capsid/coat proteins of a particular virus suggested the presence of virions in Varroa. Also, matches between the MWs of viral structural proteins on 2D-E and their theoretical MWs indicated that viruses were not digested. The absence/scarce detection of non-structural proteins compared with high-abundance structural proteins suggest that the viruses did not replicate in the mite; hence, virions accumulate in the Varroa gut via hemolymph feeding. Hemolymph feeding also resulted in the detection of a variety of honeybee proteins. The advantages of MS-based proteomics for pathogen detection, false-positive pathogen detection, virus replication, posttranslational modifications and the presence of honeybee proteins in Varroa are discussed.
Updating stored memory requires adult hippocampal neurogenesis
Authors: Suárez-Pereira Irene , Carrión Ángel M
Published: September 2015

Adult hippocampal neurogenesis appears to influence hippocampal functions, such as memory formation for example. While adult hippocampal neurogenesis is known to be involved in hippocampal-dependent learning and consolidation processes, the role of such immature neurons in memory reconsolidation, a process involved in the modification of stored memories, remains unclear. Here, using a novel fast X-ray ablation protocol to deplete neurogenic cells, we have found that adult hippocampal neurogenesis is required to update object recognition stored memory more than to reinforce it. Indeed, we show that immature neurons were selectively recruited to hippocampal circuits during the updating of stored information. Thus, our data demonstrate a new role for neurogenesis in cognitive processes, adult hippocampal neurogenesis being required for the updating of stored OR memories. These findings suggest that manipulating adult neurogenesis may have a therapeutic application in conditions associated with traumatic stored memory, for example.

Published: September 2015

We demonstrate dynamic reversible switching of VO2 insulator-to-metal transition (IMT) locally on the scale of 15 nm or less and control of nanoantennas, observed for the first time in the near-field. Using polarization-selective near-field imaging techniques, we simultaneously monitor the IMT in VO2 and the change of plasmons on gold infrared nanoantennas. Structured nanodomains of the metallic VO2 locally and reversibly transform infrared plasmonic dipole nanoantennas to monopole nanoantennas. Fundamentally, the IMT in VO2 can be triggered on femtosecond timescale to allow ultrafast nanoscale control of optical phenomena. These unique features open up promising novel applications in active nanophotonics.

Dewetting dynamics of a gold film on graphene: implications for nanoparticle formation
Authors: Namsani Sadanandam , Singh Jayant K.
Published: September 2015

The dynamics of dewetting of gold films on graphene surfaces is investigated using molecular dynamics simulation. The effect of temperature (973–1533 K), film diameter (30–40 nm) and film thickness (0.5–3 nm) on the dewetting mechanism, leading to the formation of nanoparticles, is reported. The dewetting behavior for films ≤5 Å is in contrast to the behavior seen for thicker films. The retraction velocity, in the order of ∼300 m s−1 for a 1 nm film, decreases with an increase in film thickness, whereas it increases with temperature. However at no point do nanoparticles detach from the surface within the temperature range considered in this work. We further investigated the self-assembly behavior of nanoparticles on graphene at different temperatures (673–1073 K). The process of self-assembly of gold nanoparticles is favorable at lower temperatures than at higher temperatures, based on the free-energy landscape analysis. Furthermore, the shape of an assembled structure is found to change from spherical to hexagonal, with a marked propensity towards an icosahedral structure based on the bond-orientational order parameters.

Triple‐stage path prediction algorithm for real‐time mission planning of multi‐UAV
Authors: Sun Xiaolei , Liu Yanfang , Yao Weiran , Qi Naiming
Published: September 2015

A triple‐stage path prediction algorithm is proposed for real‐time mission planning. In every planning horizon, each unmanned aerial vehicle (UAV) utilises the A* algorithm first to estimate the path to every task. Then, the estimated result serve as the input of the cluster method to generate the quasi‐optimal task assignment. The shortest path to the assigned task is further calculated using the A* algorithm. Finally, it is smoothed to obtain the flyable reference path to guide the UAV by using the cubic B‐spline curve. Numerical experiments demonstrate the effectiveness and efficiency of the proposed algorithm.
State estimation with quantised innovations and communication channels
Authors: Guo Jin , Zhao Yanlong , Sun Chang‐Yin
Published: September 2015

This study considers the minimum mean‐squared error (MMSE) state estimation for the discrete linear stochastic systems subject to both the quantisation and the communication unreliability. Based on the binary quantised innovation and a binary symmetric channel, the recursive MMSE estimator is established, and its performance is analysed. It is also discussed how the quantisation scheme and the communication uncertainty jointly affect the estimation quality. Consequently, the related results are extended to the case of the time‐invariant discrete memoryless channel. Numerical simulations are included to illustrate the main results obtained.
Feature structure fusion modelling for classification
Authors: Lin Guangfeng , Zhu Hong , Kang Xiaobing , Miu Yalin , Zhang Erhu
Published: September 2015

Structure fusion (SF) has been presented for multiple feature fusion via mining the discriminative and complementary information from different feature sets. As the typical methods, SF based on locality preserving projections (SFLPP) and SF based on tensor subspace analysis (SFTSA) have been developed for classification by capturing the complete structure from different features. However, the jointed optimisation function of SFLPP or SFTSA does not clearly explain the modelling mechanism of SF, and its solving process is complex because of iterative eigenvalue decomposition. In this study, structure modelling based on maximisation posterior probability (SMMPP) is proposed for solving these issues. It jointly considers both the certain prior structure (the mutual structure of multiple feature structure described by Ising model) and the uncertain likelihood structure (the possible fusion structure of multiple feature structure represented by Markov random field model) into the framework of Bayes’ rule. The proposed computational solution is faster‐converging speed than SFLPP or SFTSA with the guarantee of convergence. Extensive experiments conducted on shape analysis and human action recognition demonstrate the superiority of SMMPP over the state of art methods.
