Driving Decisions: Distinguishing Evaluations, Providers and Outcomes
(2018-05-11)
Driving is a highly valued instrumental activity of daily living on which many older adults depend for access to their community. The demand to address driving is changing as older adults experience increasing longevity ...
Early Mobility in the Hospital: Lessons Learned from the STRIDE Program
(2018-09-26)
Immobility during hospitalization is widely recognized as a contributor to deconditioning, functional loss, and increased need for institutional post-acute care. Several studies have demonstrated that inpatient walking ...
Effects of finite coverage on global polarization observables in heavy ion collisions
(2018-05-10)
In non-central relativistic heavy ion collisions, the created matter possesses a large initial orbital angular momentum. Particles produced in the collisions could be polarized globally in the direction of the orbital ...
The best of both worlds? A review of delayed selfing in flowering plants
(2018-04-06)
PREMISE OF STUDY: In a seminal body of theory, Lloyd showed that the fitness consequences of selfing will depend on its timing in anthesis. Selfing that occurs after opportunities for outcrossing or pollen dispersal can ...
The effects of emotional states and traits on time perception
(2018-08-20)
Background: Models of time perception share an element of scalar expectancy theory known as the internal clock, containing specific mechanisms by which the brain is able to experience time passing and function effectively. ...
Strongly interacting matter under rotation
(2018-02-02)
The vorticity-driven effects are systematically studied in various aspects. With AMPT the distributions of vorticity has been investigated in heavy ion collisions with different collision parameters. Taking the rotational ...
Spontaneous bile duct perforation in a neonate
(2018-08-14)
We present a case of spontaneous biliary perforation (SBP) in a previously healthy 3-week-old boy with wor- sening scleral icterus, abdominal distension, and acholic stools. Abdominal ultrasound demonstrated moderate ascites ...
Bacteroides fragilis requires the ferrous-iron transporter FeoAB and the CobN-like proteins BtuS1 and BtuS2 for assimilation of iron released from heme
(2018-05-07)
The intestinal commensal and opportunistic anaerobic pathogen Bacteroides fragilis has an essential requirement for both heme and free iron to support growth in extraintestinal infections. In the absence of free iron, B. ...
Step-wise evolution of complex chemical defenses in millipedes: a phylogenomic approach
(2018-02-16)
With fossil representatives from the Silurian capable of respiring atmospheric oxygen, millipedes
are among the oldest terrestrial animals, and likely the first to acquire diverse and complex chemical defenses against ...
Stem cell models of human synapse development and degeneration
(2018-11-26)
Many brain disorders exhibit altered synapse formation in development or syn- apse loss with age. To understand the complexities of human synapse development and degeneration, scientists now engineer neurons and brain ...
