The mechanics of reversible adhesion of the gecko is investigated in terms of the attachment and detachment mechanisms of the hierarchical microstructures on its toe. At the bottom of the hierarchy, we show that a spatula pad of tiny thickness can be well absorbed onto a substrate with a large surface area and a highly constrained decohesion process zone, both of which are beneficial for robust...

The Khushab anticline is located in the Zagros fold-thrust belt in the Lurestan. This anticline is affected by the Balarud fault zone, which is a part of Mountain Front Fault between the Lurestan and Dezful Embayment zones. Based on the measurement of the elements of fold style, this anticline is analyzed. According to these measurements, this anticline is a noncylindrical, asymmetrical and dis...

Abstract. Back-arc extension superimposed on mountain belts leads to distributed normal faults and shear zones interacting with magma emplacement within the crust. The composition of granitic magmas emplaced at this stage often involves a large component crustal melting. Miocene Aegean granitoids were in metamorphic core complexes (MCCs) below crustal-scale low-angle ductile zones. Intrusion pr...

effective approach to defining additional resources using 3-D seismic as the sole data source. Although this example is from a densely drilled province, such a seismic-based approach is often used in frontier areas with sparse well coverage, in step-out regions around known production, can be used for a “quick look” evaluation of existing properties, and for real-time interpretation of newly ac...

Main Outcome Measures: Investigators documented the location, extent, and severity of ROP during serial retinal examinations. The onset of the ROP’s involution was determined from a review of these data, applying a set of predetermined criteria. Results: Acute-phase ROP began to involute at a mean of 38.6 weeks postmenstrual age. In 90% of patients, the ROP began to involute before 44 weeks of ...

The analysis of heat flow, seismic, and topographic data collected in the northern NorwegianGreenland Sea reveals an asymmetric evolution of the Eurasian and North American plates. These data are compared to predictions from three kinematic models of extension which produce asymmetry about the Knipovich Ridge: (1) uniform asymmetric pure shear, (2) lithospheric simple shear, and (3) rift/ridge ...

Retinal detachment surgery has been considered an inpatient hospital procedure requiring preoperative and postoperative hospitalization. In this pilot study, outpatient retinal detachment surgery was performed on sixteen patients and the results (100% success rate after an average follow-up of 8.3 months) were comparable or better than reported overall success rates for retinal detachment ...

. . . the war is too important to leave it to the generals, the medicine is too important to leave it to the doctors, the science is too important to leave it to the scientist. . . In this issue of the AJNR, Kwon et al describe “technical problems associated with new designs of Guglielmi Detachable coil [GDC]”; namely, device malfunction, such as the spontaneous detachment of GDC coils, coil ba...

During the two winters between 2003 and 2005, a land-based marine radar observed the nearshore ice motion during the development and decay of landfast ice near Barrow, Alaska. The radar imagery captured individual events at high temporal resolution, revealing deformation processes and allowing calculation of ice velocity and acceleration. Atmospheric forcing during these events appeared to be i...
