MIT engineers grow “perfect” atom-thin materials on industrial silicon wafers（图）
工业硅晶圆 原子薄材料 芯片

True to Moore’s Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon — the backbone of modern transist...
Perfect Pipelining: A New Loop Parallelization Technique
Pipelining Loop Parallelization Technique
2016/5/25
Parallelizing compilers do not handle loops in a satisfactory manner. Fine-grain transformations capture irregular parallelism inside a loop body not amenable to coarser approaches but have limited ab...
A mechanism on the drug release into a perfect sink from a coated planar matrix with a super-saturation loading in the core
Coated planar matrix Controlled release Mathematical analysis In-vitro release
2016/3/25
A comprehensive model is proposed to accurately describe drug release kinetics from a coated plane sheet when drug loading in the core is above its saturation level. The general solutions are acquired...
EXPERIENCE-BASED LEARNING AND E-LEARNING:A PERFECT COMBINATION
surveying education experience-based learning e-learning natural resource management
2016/1/29
The discussion on the changing nature of the surveying profession has been a key issue for more than a decade. University and training institutions have been looking for new ways to respond to these c...
Penn Engineers Show How “Perfect” Materials Begin to Fail
Penn Engineers Perfect Materials Begin to Fail
2015/6/18
Crystalline materials have atoms that are neatly lined up in a repeating pattern. When they break, that failure tends to start at a defect, or a place where the pattern is disrupted. But how do defect...
IMAGES ARE AN OUTSTANDING EVIDENCE ON RAPID DEVELOPMENT “A PERFECT EXAMPLE FROM UNITED ARAB EMIRATES (UAE)”
Developing Countries Space Urban Education Building International
2015/6/1
Before 1960’s, UAE was a poor developing country, and almost there were no real signs of civilization. During the 1970’s two important things happened: H. H. Sheikh Zayed Bin Sultan Al Nahyan, the pre...

Perfect colors captured with one ultra-thin lens
2015/3/4
Most lenses are, by definition, curved. After all, they are named for their resemblance to lentils, and a glass lens made flat is just a window with no special powers.But a new type of lens created at...
Researchers at Rice University have created flexible, patterned sheets of multilayer graphene from a cheap polymer by burning it with a computer-controlled laser. The process works in air at room temp...
Condition for perfect antireflection by optical resonance at material interface
Condition perfect antireflection optical resonance material interface
2015/8/6
Reflection occurs at an air–material interface. The development of antireflection schemes, which aims to cancel such reflection, is important for a wide variety of applications including solar cells a...
Scientists at The University of Queensland (UQ) have discovered how the honeybee can land anywhere with utmost precision and grace – and the knowledge may soon help build incredible robot aircraft.
AbstractMany implications and unavoidable imperfects in software practices, as the uncontrollable and the unknown parts, offend the foundation of most existed methodologies. Perfect ball is based on t...
