Anomalous Payloadbased Worm Detection and Signature Generation.

In a previous article, I had a conversation with former-CIA chief Jim Woolsey to discuss one of America’s greatest national security vulnerabilities, its power grid. The issues that Woolsey has been concerned with for over a decade has been the ease in which a terrorist group or other actor (think North Korea for example) could attack the grid and plunge the country into darkness for months, if not years. And if that seems far-fetched, just recall how a tree limb fell in Ohio in 2003 and blacked out the entire Northeast and part of Canada for several days.

According to the most recent issue of the "Monthly Energy Review" by the U.S. Energy Information Administration (EIA), with data through June 30, 2013, renewable energy sources (i.e., biofuels, biomass, hydropower, geothermal, solar, and wind) provided 9.81 percent of U.S. energy consumption and 11.82 percent of domestic energy production for the first half of 2013.

The U.S. brought online nearly 700 MW of new electricity generation in October, and practically all of it was large-scale solar energy, according to data from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects.

U.K. renewable power generation rose 28 percent last year as more wind farms and solar plants came online, the Department of Energy and Climate Change said.

More than any other leader in modern history, Nelson Mandela understood that a society must bridge divides and work together to thrive. He also firmly believed that we must strive to leave our children with a safer, more peaceful and more prosperous world than the one we inherited. He said that “there can be no keener revelation of a society’s soul than the way in which it treats its children”.

A multi-color light source is a significant tool for nonlinear optics experiments, pump–dump/repump–probe experiments and in other fields. Here, a novel method is proposed to create three-color pulses based on a high-gain harmonic-generation (HGHG) free-electron laser with a tilted electron bunch. In this method, the initial bunch tilt is created by transverse wakefields after the bunch passes through a corrugated structure with an off-axis orbit, and is further enlarged in a following drift section. Then the tilted bunch experiences the off-axis field of a quadrupole magnet to cool down the large transverse velocity induced before. After that, it enters an HGHG configuration adopting a transverse gradient undulator (TGU) as the radiator, where only three separated fractions of the tilted bunch will resonate at three adjacent harmonics of the seed wavelength and are enabled to emit three-color pulses simultaneously. In addition, the use of the natural transverse gradient of a normal planar undulator instead of the TGU radiator to emit three-color pulses is also studied in detail. Numerical simulations including the generation of the tilted bunch and the free-electron laser radiation confirm the validity and feasibility of this scheme both for the TGU radiator and the natural gradient in the extreme-ultraviolet waveband.

An analysis of the coherence properties of the fourth-generation high-energy storage rings with emittance values of 10 pm rad is performed. It is presently expected that a storage ring with these low emittance values will reach diffraction limit at hard X-rays. Simulations of coherence properties were performed with the XRT software and an analytical approach for different photon energies from 500 eV to 50 keV. It was demonstrated that a minimum photon emittance (diffraction limit) reached at such storage rings is λ/2π. Using mode decomposition it is shown that, for the parameters of the storage ring considered in this work, the diffraction limit will be reached for soft X-ray energies of 500 eV. About ten modes will contribute to the radiation field at 12 keV photon energy and even more modes give a contribution at higher photon energies. Energy spread effects of the electron beam in a low-emittance storage ring were analysed in detail. Simulations were performed at different relative energy spread values from zero to 2 × 10−3. A decrease of the degree of coherence with an increase of the relative energy spread value was observed. This analysis shows that, to reach the diffraction limit for high photon energies, electron beam emittance should go down to 1 pm rad and below.

Direct electron detectors (DEDs) have revolutionized cryo-electron microscopy (cryo-EM) by facilitating the correction of beam-induced motion and radiation damage, and also by providing high-resolution image capture. A new-generation DED, the DE64, has been developed by Direct Electron that has good performance in both integrating and counting modes. The camera has been characterized in both modes in terms of image quality, throughput and resolution of cryo-EM reconstructions. The modulation transfer function, noise power spectrum and detective quantum efficiency (DQE) were determined for both modes, as well as the number of images per unit time. Although the DQE for counting mode was superior to that for integrating mode, the data-collection throughput for this mode was more than ten times slower. Since throughput and resolution are related in single-particle cryo-EM, data for apoferritin were collected and reconstructed using integrating mode, integrating mode in conjunction with a Volta phase plate (VPP) and counting mode. Only the counting-mode data resulted in a better than 3 Å resolution reconstruction with similar numbers of particles, and this increased performance could not be compensated for by the increased throughput of integrating mode or by the increased low-frequency contrast of integrating mode with the VPP. These data show that the superior image quality provided by counting mode is more important for high-resolution cryo-EM reconstructions than the superior throughput of integrating mode.

The analysis of large structural databases reveals general features and relationships among proteins, providing useful insight. A different approach is required to characterize ubiquitous secondary-structure elements, where flexibility is essential in order to capture small local differences. The ALEPH software is optimized for the analysis and the extraction of small protein folds by relying on their geometry rather than on their sequence. The annotation of the structural variability of a given fold provides valuable information for fragment-based molecular-replacement methods, in which testing alternative model hypotheses can succeed in solving difficult structures when no homology models are available or are successful. ARCIMBOLDO_BORGES combines the use of composite secondary-structure elements as a search model with density modification and tracing to reveal the rest of the structure when both steps are successful. This phasing method relies on general fold libraries describing variations around a given pattern of β-sheets and helices extracted using ALEPH. The program introduces characteristic vectors defined from the main-chain atoms as a way to describe the geometrical properties of the structure. ALEPH encodes structural properties in a graph network, the exploration of which allows secondary-structure annotation, decomposition of a structure into small compact folds, generation of libraries of models representing a variation of a given fold and finally superposition of these folds onto a target structure. These functions are available through a graphical interface designed to interactively show the results of structure manipulation, annotation, fold decomposition, clustering and library generation. ALEPH can produce pictures of the graphs, structures and folds for publication purposes.

The neutron powder diffractometer POWGEN at the Spallation Neutron Source has recently (2017–2018) undergone an upgrade which resulted in an increased detector complement along with a full overhaul of the structural design of the instrument. The current instrument has a solid angular coverage of 1.2 steradians and maintains the original third-generation concept, providing a single-histogram data set over a wide d-spacing range and high resolution to access large unit cells, detailed structural refinements and in situ/operando measurements.

The structural and nonlinear optical properties of a new anilinium hybrid crystal of chemical formula (C6H7NCl+·NO3−)3 have been investigated. The crystal structure was determined from single-crystal X-ray diffraction measurements performed at a temperature of 100 K which show that the compound crystallizes in a noncentrosymmetric space group (Pna21). The structural analysis was coupled with Hirshfeld surface analysis to evaluate the contribution of the different intermolecular interactions to the formation of supramolecular assemblies in the solid state that exhibit nonlinear optical features. This analysis reveals that the studied compound is characterized by a three-dimensional network of hydrogen bonds and the main contributions are provided by the O...H, C...H, H...H and Cl...H interactions, which alone represent ∼85% of the total contributions to the Hirshfeld surfaces. It is noteworthy that the halogen...H contributions are quite comparable with those of the H...H contacts. The nonlinear optical properties were investigated by nonlinear diffuse femtosecond-pulse reflectometry and the obtained results were compared with those of the reference material LiNbO3. The hybrid crystals exhibit notable second (SHG) and third (THG) harmonic generation which confirms its polarity is generated by the different intermolecular interactions. These measurements also highlight that the THG signal of the new anilinium compound normalized to its SHG counterpart is more pronounced than for LiNbO3.

Brownfield regeneration and land use planning are complex issues which encompass many different environmental, economic and social dimensions. This Thematic Issue brings together quality research into brownfield regeneration, which highlights insights and successful strategies from across Europe and beyond.

High levels of waste production must be tackled as part of the move towards sustainable living. Recent research has used Sweden as a case study to assess the strength of suitable policies and strategies that are required to break the link between economic growth and waste generation.

A recent study highlights the role of the public sector in encouraging private investment in natural and cultural brownfield regeneration projects by analysing four models of financing: public-private partnerships, land value finance mechanisms, urban development funds and impact investment funds. Local governments, it is suggested, are well placed to identify and select the most suitable financing mechanisms for redevelopment projects.

A study has evaluated the Municipal Urbanisation Tax (MUT)—a specific tax for the construction, maintenance, and reinforcement of urban infrastructure—in the city of Tomar, Portugal. The city has a new formula for the tax which is simpler and reinforces efforts to contain urban sprawl. The MUT is a one-time charge applied to new development through land subdivision (Loteamento) or individual buildings, similar to an impact fee. Other municipalities aiming to direct urban regeneration towards their brownfield sites, for example, could learn from the Portuguese experiences.

A new study from Belgium has gathered community views of brownfield regeneration. Results indicate that the often overlooked aspect of landscape quality, such as green spaces, visually-attractive areas and cultural heritage, is important in people’s opinions of brownfield regeneration schemes.

Low oxygen levels (‘hypoxia’) are a pressing concern for marine and freshwater ecosystems worldwide, and this may deteriorate as ocean temperatures rise. Hypoxia causes stress in organisms, which can cause reproductive impairments that persist across generations — even the offspring that have never been exposed to hypoxia. Previous studies discovered that hypoxia can disrupt sex hormones, resulting in birth defects and affecting reproduction of male fish over several generations. This study shows how hypoxia can also affect female marine medaka (Oryzias melastigma) over multiple generations — and thus may pose a significant threat to the sustainability of natural fish populations worldwide.

A recent study has compared the impact of future power generated from large, central stations with power generated from smaller distributed generators (DG) in California on air quality. It concluded that although DG produces more emissions, its impact on air quality is likely to be smaller than central power stations due to complex interactions between air chemistry and transport.
