Microperforated panel (MPP) absorbers are promising as a basis for the next-generation of sound absorbing materials. A microperforated panel absorber is backed by an air-cavity with a rigid-back wall and its typical use is for a sound-absorbing ceiling. However, MPPs have some limitations and disadvantages: its sound absorbing mechanism is limited to a Helmholtz resonator caused by perforations...

Masking period patterns (MPPs) were measured in listeners with normal and impaired hearing using amplitude-modulated tonal maskers and short tonal probes. The frequency of the masker was either the same as the frequency of the probe (on-frequency masking) or was one octave below the frequency of the probe (off-frequency masking). In experiment 1, MPPs were measured for listeners with normal hea...

Lymphoid and myeloid lineage segregation is a major developmental step during early hematopoiesis from hematopoietic stem cells. It is not clear, however, whether multipotent progenitors (MPPs) adopt a lymphoid or myeloid fate through stochastic mechanisms, or whether this process can be regulated by extracellular stimuli. In this study, we show that lymphoid lineage specification occurs in MPP...

The health care industry has undergone radical change because of the implementation of the Medicare Prospective Payment System (MPPS). This study is an assessment of the effect of MPPS on Level II fieldwork. Six factors that have the potential to influence fieldwork delivery patterns formed the basis of a questionnaire that was mailed to 23 occupational therapy directors in acute care Wisconsin...

During the past decade massively parallel processors (MPPs) have slowly gained acceptancewithin the scientiic community. At present these machines typically contain a few hundred to one thousand oo-the-shelf microprocessors and a total memory of up to 32 GBytes. The potential performance of these machines is illustrated by the fact that a month long job on a high end workstation might require o...

The thymus requires continuous replenishment of progenitors from the bone marrow (BM) to sustain T cell development. However, it remains unclear which hematopoietic progenitors downstream from hematopoietic stem cells in the BM home to the thymus in adult mice. In this work, we demonstrate that although multiple BM populations have intrinsic T lineage differentiation potential, a small subset o...

Multiplicative programming problems (MPPs) are global optimisation problems known to be NP-hard. In this paper, we employ algorithms developed to compute the entire set of nondominated points of multi-objective linear programming (MOLP) problems to solve linear MPPs. First, we improve our own objective space cut and bound algorithm for convex MPPs in the special case of linear MPPs by only solv...

In this paper we have characterized the inter-arrival time and service time distributions for jobs at a large MPP supercomputing center. Our findings show that the distributions are dispersive and complex enough that they require Hyper Erlang distributions to capture the first three moments of the observed workload. We also present the parameters from the characterization so that they can be ea...

Targeted mRNA trafficking and local translation may play a significant role in controlling protein localization. Here we examined for the first time the localization of all ( approximately 50) mRNAs encoding peroxisomal proteins (mPPs) involved in peroxisome biogenesis and function. By using the bacteriophage MS2-CP RNA-binding protein (RBP) fused to multiple copies of GFP, we demonstrated that...
