Older patients are increasingly undergoing allogeneic hematopoietic transplantation. A relevant question is whether outcomes can be improved with a younger allele-level 8/8 HLA-matched unrelated donor (MUD) rather than an older HLA-matched sibling (MSD). Accordingly, transplants in leukemia/lymphoma patients age ≥50 years were analyzed comparing outcomes for recipients of MSD ≥50 (n = 1415) ver...
House mice (Mus musculus) emit complex ultrasonic vocalizations (USVs) during social and sexual interactions, which have features similar to bird song (i.e., they are composed of several different types of syllables, uttered in succession over time to form a pattern of sequences). Manually processing complex vocalization data is time-consuming and potentially subjective, and therefore, we devel...
In this paper, the effect of plant density, sediment type, and macrophyte fragment size on the fragment colonization ability of Myriophyllum spicatum was evaluated in an outdoor experiment. The relative growth rate (RGR) was higher in the mud and low-density treatments than in the sand and high-density treatments. The relative elongation rate (RER) decreased with increasing density and fragment...
In paper based on the results of previous studies and latest investigations of mud volcanoes in the South Caspian basin the depth occurrence of fluid, mud and rocks are calculated and modeled. Major factors causing formation of diapirism/mud volcanism in the South Caspian basin are Pliocene-Quaternary high sedimentation rates (up to 3 km/my), super thick sedimentary cover (up to 25 30 km), pred...
Mobile radio communication systems are affected by the frequency and time selectivity of radio channel due to multipath propagation and Doppler shifts. In an Orthogonal Frequency Division Multiplexing (OFDM) based Code Division Multiple Access (CDMA) system, the spreading schemes will suffer loss of orthogonality between codewords of different users. In this thesis, basic system model of severa...
OBJECTIVES The objective of this study was to evaluate the effects and the tolerability of mud packs and thermal baths in a group of patients affected with this disease. METHODS Twenty-four patients with spondylitis and Crohn's disease or ulcerative colitis, treated with 5-ASA or sulfasalazine, were randomised and assessed by an investigator independent from the spa staff: 12 were submitted t...
gases and liquids in the subsurface erupt to the surface, carrying slurries of fluid, mud, and millimeter-to-meter sized rocks [12-14]. The driving force is generally a combination of overpressure and compression. These conditions often occur in orogenic belts and involve hydrocarbon generation, but other mechanisms (e.g. rapid sedimentation with gas hydrate destabilization or clay dewatering) ...
Creating digital archives of personal and family memories is an area of growing interest, but which seemingly is often not supported by a thorough understanding of current home archiving practice. In this paper we seek to excavate the home archive. Based on extensive field research in family homes we present a taxonomy of the kinds of sentimental objects to be found in homes, and through in-dep...
Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The comet's outer layer is composed of 1- to 100-micrometer fine particles with negligible strength (<65 pascals). Local gravitational field and average nucleus density (600 kilograms per cubic meter) are estimated from ejecta fallback. Initial ejecta were hot (>1000 kelvins). A large increase in organic materi...
Burrowers and borers are ecosystem engineers that alter their physical environments through bioturbation, bioirrigation and bioerosion. The mechanisms of moving through solid substrata by burrowing or boring depend on the mechanical properties of the medium and the size and morphology of the organism. For burrowing animals, mud differs mechanically from sand; in mud, sediment grains are suspend...
