Given the controversies and difficulties which preceded the coming into force of the Lisbon Treaty, it is easy to forget that the Treaty is a complex legal document in need of detailed analysis for ...its impact to be fully understood. Jean-Claude Piris, the Director General of the Legal Service of the Council of the European Union, provides such an analysis, looking at the historical and political contexts of the Treaty, its impact on the democratic framework of the EU and its provisions in relation to substantive law. Impartial legal analysis of the EU's functions, its powers and the treaties which govern it make this the seminal text on the most significant recent development in EU law.
"A bridge shouldn't just fall down," Senator Amy Klobuchar said after the August 1, 2007, collapse of the Minneapolis I-35W eight-lane steel truss bridge, which killed 13 motorists, injured 145, and ...left a collective wound on the city's psyche and infrastructure.On her way to a soccer game with a fellow teammate, Kimberly J. Brown experienced the collapse firsthand, falling 114 feet in her teammate's car to the Mississippi River. Although terrified, injured, and in shock, she survived. In this sobering memoir and exposé, Brown recounts her harrowing experience.In the aftermath of the disaster, Brown became both an advocate for survivors and an unofficial whistle-blower about decaying infrastructure. She details her investigation and correspondence with Thornton Tomasetti engineers, including the false official account of the collapse and the eventual revelation of its real causes. In addition, she chronicles the ongoing decay of America's bridges and the continuing challenges faced by leaders to address infrastructure problems across the country.After nearly a decade of research into the collapse and her active and ongoing recovery from psychic and physical injuries, Brown shares her experience and answers the questions we should all be asking: Why did this bridge collapse? And what could have been done to prevent this tragedy?
Context. A stellar occultation by a trans-Neptunian object (TNO) provides an opportunity to probe the size and shape of these distant solar system bodies. In the past seven years, several ...occultations by TNOs have been observed, but mostly from a single location. Only very few TNOs have been sampled simultaneously from multiple locations. Sufficient data that enable a robust estimation of shadow size through an ellipse fit could only be obtained for two objects. Aims. We present the first observation of an occultation by the TNO 2007 UK126 on 15 November 2014, measured by three observers, one nearly on and two almost symmetrical to the shadow’s centerline. This is the first multi-chord dataset obtained for a so-called detached object, a TNO subgroup with perihelion distances so large that the giant planets have likely not perturbed their orbits. We also revisit Herschel/PACS far-infrared data, applying a new reduction method to improve the accuracy of the measured fluxes. Combining both datasets allows us to comprehensively characterize 2007 UK126. Methods. We use error-in-variable regression to solve the non-linear problem of propagating timing errors into uncertainties of the ellipse parameters. Based on the shadow’s size and a previously reported rotation period, we expect a shape of a Maclaurin spheroid and derive a geometrically plausible size range. To refine our size estimate of 2007 UK126, we model its thermal emission using a thermophysical model code. We conduct a parametric study to predict far-infrared fluxes and compare them to the Herschel/PACS measurements. Results. The favorable geometry of our occultation chords, combined with minimal dead-time imaging, and precise GPS time measurements, allow for an accurate estimation of the shadow size (best-fitting ellipse with axes 645.80 ± 5.68 km × 597.81 ± 12.74 km) and the visual geometric albedo (pV = 15.0 ± 1.6%). By combining our analyses of the occultation and the far-infrared data, we can constrain the effective diameter of 2007 UK126 to deff = 599−629 km. We conclude that subsolar surface temperatures are in the order of ≈ 50−55 K.
Seismic data reveal that the aftershock zone expands with time after a main shock event. Here we examine the aftershock sequence recorded during the first 32 days following the 2007 Noto‐Hanto ...earthquake, Japan. By applying a matched‐filter technique to the data, we detected about 10 times more events than those listed in the routinely constructed earthquake catalog. The aftershock area expanded along the fault strike as a logarithmic function of time, beginning immediately after the main shock. Aftershock expansion toward the SW was especially extensive and developed more rapidly than toward the NE. Interestingly, the aftershock area expanded in a step‐like manner by the activation of a series of spatially clustered seismic bursts. Spatial correlation between the aftershock extension and the afterslip distribution suggests that the expansion of the aftershock area could be mainly driven by aseismic afterslip. The aftershock area continues to expand, even though 7 years have now passed since the main shock.
Key Points
Aftershock area expanded along fault strike as a logarithmic function of time
Seismicity front migrated in a step‐like manner by activation of seismic bursts
Expansion of the aftershock area could be mainly driven by aseismic afterslip
On August 1, 2007, just after 6:00 p.m., during the evening rush hour in Minneapolis, the 1,900-foot-long, eight-lane I-35W bridge buckled and crashed into the Mississippi River. The unimaginable had ...happened right on the doorstep of the University of Minnesota Twin Cities campus. Many of the first responders were from the University, persevering in the midst of chaos and disbelief. In the ensuing weeks, research and engineering teams from the University reviewed the wreckage, searched for causes, and began planning for the future.
The City, the River, the Bridgerepresents another set of responses to the disaster. Stemming from a 2008 University of Minnesota symposium on the bridge collapse and the building of a new bridge, it addresses the ramifications of the disaster from the perspectives of history, engineering, architecture, water science, community-based journalism, and geography. Contributors examine the factors that led to the collapse, the lessons learned from the disaster and the response, the policy and planning changes that have occurred or are likely to occur, and the impact on the city and the Mississippi River.The City, the River, the Bridgedemonstrates the University's commitment to issues that concern the community and shares insights on public questions of city building, infrastructure, and design policy.

Conventional treatment for primary dysmenorrhoea has a failure rate of 20% to 25% and may be contraindicated or not tolerated by some women. Chinese herbal medicine may be a suitable alternative.
To ...determine the efficacy and safety of Chinese herbal medicine for primary dysmenorrhoea when compared with placebo, no treatment, and other treatment.
The Cochrane Menstrual Disorders and Subfertility Group Trials Register (to 2006), MEDLINE (1950 to January 2007), EMBASE (1980 to January 2007), CINAHL (1982 to January 2007), AMED (1985 to January 2007), CENTRAL (The Cochrane Library issue 4, 2006), China National Knowledge Infrastructure (CNKI, 1990 to January 2007), Traditional Chinese Medicine Database System (TCMDS, 1990 to December 2006), and the Chinese BioMedicine Database (CBM, 1990 to December 2006) were searched. Citation lists of included trials were also reviewed.
Any randomised controlled trials involving Chinese herbal medicine versus placebo, no treatment, conventional therapy, heat compression, another type of Chinese herbal medicine, acupuncture or massage. Exclusion criteria were identifiable pelvic pathology and dysmenorrhoea resulting from the use of an intra-uterine contraceptive device.
Quality assessment, data extraction and data translation were performed independently by two review authors. Attempts were made to contact study authors for additional information and data. Data were combined for meta-analysis using either Peto odds ratios or relative risk (RR) for dichotomous data or weighted mean difference for continuous data. A fixed-effect statistical model was used, where suitable. If data were not suitable for meta-analysis, any available data from the trial were extracted and presented as descriptive data.
Thirty-nine randomised controlled trials involving a total of 3475 women were included in the review. A number of the trials were of small sample size and poor methodological quality. Results for Chinese herbal medicine compared to placebo were unclear as data could not be combined (3 RCTs). Chinese herbal medicine resulted in significant improvements in pain relief (14 RCTs; RR 1.99, 95% CI 1.52 to 2.60), overall symptoms (6 RCTs; RR 2.17, 95% CI 1.73 to 2.73) and use of additional medication (2 RCTs; RR 1.58, 95% CI 1.30 to 1.93) when compared to use of pharmaceutical drugs. Self-designed Chinese herbal formulae resulted in significant improvements in pain relief (18 RCTs; RR 2.06, 95% CI 1.80 to 2.36), overall symptoms (14 RCTs; RR 1.99, 95% CI 1.65 to 2.40) and use of additional medication (5 RCTs; RR 1.58, 95% CI 1.34 to 1.87) after up to three months of follow-up when compared to commonly used Chinese herbal health products. Chinese herbal medicine also resulted in better pain relief than acupuncture (2 RCTs; RR 1.75, 95% CI 1.09 to 2.82) and heat compression (1 RCT; RR 2.08, 95% CI 2.06 to 499.18).
The review found promising evidence supporting the use of Chinese herbal medicine for primary dysmenorrhoea; however, results are limited by the poor methodological quality of the included trials.
The 14 November 2007 Tocopilla (MW 7.7) earthquake was the first large rupture (M > 7.5) in the 1877 Northern Chile seismic gap. The event only ruptured the lower seismogenic part of the megathrust, ...raising questions about the mechanism that prevented the trenchward rupture propagation. Here, we present the short-period rupture process of the Tocopilla earthquake from local strong-motion (2.0–8.0 Hz) and teleseismic (0.5–2.0 Hz) back-projections. P and pP teleseismic back-projections were combined from two arrays formed on broadband networks in North America and Africa. The kinematics of the earthquake rupture was also characterized by back-propagating S-wave envelopes from local accelerometers (≤ 200 km from the mainshock). The results show a complex rupture process, including a sub-event, from the distribution of short-period rupture emissions and the main slip asperities. The sub-event location agrees with published estimates based on S-wave arrivals and kinematic inversion. We also observed rupture emissions around the slip patches and systemically classified them relative to the asperities, i.e., down-dip, up-dip, and inside. The short-period emissions are balanced around the asperities, highlighting up-dip rupture emissions. We interpreted the up-dip emissions as a proxy of the high-stress gradient caused by a kink in the slab interface, proposed in previous literature to be the mechanism that arrested the trenchward propagation of the 2007 rupture. The down-dip limit of the Tocopilla event coincided approximately where the slab interface intersects the continental Moho. Thus, it is a region expected to be extensively serpentinized, i.e., the most seaward part of the mantle wedge, defining a velocity-strengthening margin and a source of short-period radiation. The high-stress gradient around the asperities is proposed to define a third source of short-period radiation that may contribute to rupture encircling emissions.
•Short-period rupture outlines both up-dip and down-dip of the main slip asperities.•Up-dip short-period emissions linked to a geometrical kink in the slab interface.•Down-dip limit of the rupture correlates with the continental Moho depth.
