This expert consensus statement is an opus magnum written by 19 Chinese leaders in blood disorders, especially in hematopoietic cell transplants. The statement covers almost every category of neoplastic and nonneoplastic conditions and many aspects of transplants including appropriate recipients, donors, pretransplant conditioning regimens, graft types and graft-versus-host disease (GvHD) preve...

T Smart Antenna Working Group of the SDR Forum is developing an application-programming interface (API) supporting interoperability and compatibility of various kinds of smart antenna systems operating in a software-defi ned radio (SDR) network following an open-architecture model. The smart antenna API consists of three components: 1. SAControl component is used for controlling the smart anten...

Scientific development is founded on the use of precisely defined units and metrics. In microscopy, important metrics include the imaging system’s magnification, field of view, depth of field, and spatial resolution. While many of these are easy to define in an unambiguous manner, the measurement of resolution can be problematic. In this Commentary, we propose the adoption of a standard imaging...

OBJECTIVE To define the range of normal for a standardized 60-second hair count in men without alopecia. DESIGN Convenience sample. SETTING Hospital-based practice. PARTICIPANTS The study included 60 healthy men (age range, 20-60 years) without evidence of alopecia. MAIN OUTCOME MEASURE Range of normal for a standardized 60-second hair count. RESULTS Among the 20- through 40-year-old ...

Future use of type Ia supernovae for cosmology aims not only to determine the equation of state of dark energy, but also to constrain possible variations in its value. To achieve this goal, supernovae need to become better calibrated standard candles — not only to improve the precision of the measurement, but more importantly to gain better control over systematic uncertainties in order to ensu...
