Starr began by describing four "encumbrances of history" that have shaped delivery of health care in America. One he termed the "welfare piggyback," referring to the channeling of governmental health services for the poor through public assistance rather than through a universal social insurance system or a national public health service, the two systems employed in Europe. The social insurance...

We proposed a time synchronization algorithm based on packet exchange mechanism for wireless sensor networks. A single-hop synchronization scheme was presented where piggyback technique and the least-squares linear regression technique were employed. Multi-hop synchronization scheme consists of topology construction algorithm, single-hop synchronization scheme and time transformation algorithm....

The paper presents a self-organizing, multihop packet radio network architecture for multimedia. This architecture relies on code division access scheme. Nodes are organized into subsets called clusters. Within a cluster, any two nodes are one hop away from each other. All links in a cluster are assigned a common spread-spectrum code. Channel access in a cluster is implemented using a round rob...

Gestures may provide the long sought-for bridge between laboratory experiences in science and scientific discourse about abstract entities. In this article, we present our results of analyzing students’ gestures and scientific discourse by supporting three assertions about the relationship between laboratory experiences, gestures, and scientific discourse. Gestures arise from the experiences in...

Xcell Journal Third Quarter 2011 Traditional telecom networks are fundamentally configured to transport voice, such as phone service. Internet services piggyback on this legacy platform. Currently, designers are creating the next-generation network (NGN) to transport data, voice and video simultaneously, providing transparency and scalability while minimizing total operational cost. The NGN is ...

During the spaceborne ISAL (Inverse Synthetic Aperture Ladar) imaging, radial velocity between piggyback satellite of ladar and observed is usually relatively large, which will introduce inner-pulse Doppler that cannot be ignored in echo. In this case, traditional “stop-and-go” assumption no longer hold, compressed result along range direction would seriously broaden. Therefore, to obtain a wel...

A sedimentological and palynological investigation was carried out on outcropping sedimentary rocks at Dogiyai, Papua, proposed to be named as the Mapia Formation. The age range is from Middle Miocene Pleistocene. lower Formation deposited Metroxylon type Nothofagus emarcida Zone, Early Pliocene. It comprised of three facies associations: tidal channel, point bar, flat deposits. tidally dominat...

Knowledge about the social behavior of sharks is a growing research field, but not many observations are available on interactions between pairs in presence passive surface bait and mainly related to aggregations. Between 2009 2018, Gansbaai, South Africa, 415 white were sighted, 525 surface-generated identified, exhibited by 169 different sharks. The mean sighting rate was 0.91 (range 0.18–1.5...
