FUSING RADAR AND VIDEO CAMERA INFORMATION FOR SEVEN DIMENSIONAL SCENE PERCEPTION

Radar sensor data can be fused with video camera data. Following fusion, the fused data may be further processed then output for use by some other software or hardware component of a system. Such an arrangement can be understood as seven dimensional (7D): three dimensional data present in the data from the camera sensor; three dimensional data present in the data from the radar sensor; and the additional dimension of time (from data from both sensors being gathered over time)

A new method for registrationbased medical image interpolation

Abstract—A new technique is presented for interpolating between grey-scale images in a medical data set. Registration between neighboring slices is achieved with a modified control grid interpolation algorithm that selectively accepts displacement field updates in a manner optimized for performance. A cubic interpolator is then applied to pixel intensities correlated by the displacement fields. Special considerations are made for efficiency, interpolation quality, and compression in the implementation of the algorithm. Experimental results show that the new method achieves good quality, while offering dramatic improvement in efficiency relative to the best competing method. Index Terms—Interpolation, reconstruction, registration. I

An NF-κB - EphrinA5-Dependent Communication between NG2+ Interstitial Cells and Myoblasts Promotes Muscle Growth in Neonates

SummarySkeletal muscle growth immediately following birth is critical for proper body posture and locomotion. However, compared with embryogenesis and adulthood, the processes regulating the maturation of neonatal muscles is considerably less clear. Studies in the 1960s predicted that neonatal muscle growth results from nuclear accretion of myoblasts preferentially at the tips of myofibers. Remarkably, little information has been added since then to resolve how myoblasts migrate to the ends of fibers. Here, we provide insight into this process by revealing a unique NF-κB-dependent communication between NG2+ interstitial cells and myoblasts. NF-κB in NG2+ cells promotes myoblast migration to the tips of myofibers through cell-cell contact. This occurs through expression of ephrinA5 from NG2+ cells, which we further deduce is an NF-κB target gene. Together, these results suggest that NF-κB plays an important role in the development of newborn muscles to ensure proper myoblast migration for fiber growth

Late cretaceous history of eolian deposition in the mid-pacific mountains, central North Pacific Ocean

Eolian dust preserved in deep-sea sediment can provide a direct historical record of global atmospheric circulation. Data from a reasonably complete Upper Cretaceous section of pelagic sediments recovered at DSDP Site 463 in the central North Pacific provides a good record of eolian activity during the time period between about 112 and 66 m.y. ago. We have isolated the eolian component from these sediments, determined its mass accumulation rate and combined these data with the mineralogy of the inorganic fraction determined by others to construct a record of eolian deposition. Volcanic input is significant during Aptian-Albian and Maastrichtian times, otherwise continentally derived minerals dominate. Mass accumulation rates of the continental eolian component range from over 500 mg/cm2/103yr during the late Albian to a low of 5 mg/cm2/103yr during Coniacian time. (For comparison, the upper Miocene to Pleistocene rate averages about 20 mg/cm2/103yr.) The temporal pattern of Late Cretaceous eolian accumulation of Site 463 generally matches known changes in sea level, suggesting that source availability is the dominant control of eolian sedimentation during that time.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24203/1/0000462.pd
