Three-dimensional potential field migration for rapid imaging of entire total-magnetic-intensity (TMI) surveys is introduced, and real time applications are discussed. Potential field migration is based on a direct integral transformation of the measured TMI data into a 3D susceptibility model, which could be directly used for interpretation or as an a priorimodel for subsequent regularized inv...

To compare the outcomes of melphalan 200 mg/m² (HDM200) and 8 Gy total marrow irradiation (TMI) delivered by helical tomotherapy plus melphalan 140 mg/m² (HDM140 + TMI 8 Gy) in newly diagnosed symptomatic multiple myeloma (MM) Asian patients. Between 2007 and 2010, nine consecutive myeloma patients who were scheduled to undergo autologous stem cell transplantation (ASCT) were studied. The patie...

In this paper, I explore sequential approaches to triangular matrix inversion (TMI). TMI is commonly performed when calculating the explicit inverse of a (dense) matrix from its LU factorization (cf. LAPACK xGETRI). Direct algorithms perform 13n 3 +O � n � flops, where the lower order terms depend on the specific implementation. Because of the structural relationship between a triangular matrix...

MEF2 (myocyte-specific enhancer factor 2) is a MADS box transcription factor that is thought to be a key regulator of myogenesis in vertebrates. Mutations in the Drosophila homologue of the mef2 gene indicate that it plays a key role in regulating myogenesis in Drosophila. We show here that the Drosophila tropomyosin I (TmI) gene is a target gene for mef2 regulation. The TmI gene contains a pro...

BACKGROUND Beam-on time in Total Marrow Irradiation (TMI) delivery with helical tomotherapy is more than 30 minutes. The purpose of this study was to investigate extended time output variation in tomotherapy machine without dose servo system and its impact on the dosimetry of TMI planning. MATERIALS AND METHODS The calibration procedures with 1800 seconds delivery were conducted. The slab and...

This paper presents a new scheme that classifies convective and stratiform (C/S) precipitation areas over oceans using microwave brightness temperature. In this scheme, data are first screened to eliminate nonraining pixels. For raining pixels, C/S indices are computed from brightness temperatures and their variability for emission (19 and 37 GHz) and scattering (85 GHz). Since lower-resolution...

was present in 79% of patients with TMI, 70% of patients with SMI and elevated serum enzymes, and 42% of patients with AP. Collateral vessels supplied the occluded artery in 91% of patients with AP, 93% of patients with SMI all had postinfarction AP and 78% of patients with TMI and postinfarction AP, but in only 35% of patients with TMI and no postinfarction AP (p < 0.01). With the treadmill st...

Tripartite mutual information (TMI) is an efficient observable to quantify the ability of a scrambler for unitary time-evolution operator with quenched many-body Hamiltonian. In this paper we give numerical demonstrations TMI in disorder-free (translationally invariant) spin models three-body and four-body multiple-spin interactions. The dynamical behavior these does not exhibit linear light co...

BACKGROUND Patient-specific dose verification for treatment planning in helical tomotherapy is routinely performed using a homogeneous virtual water cylindrical phantom of 30 cm diameter and 18 cm length (Cheese phantom). Because of this small length, treatment with total marrow irradiation (TMI) requires multiple deliveries of the dose verification procedures to cover a wide range of the targe...

Total body irradiation (TBI) is an important part of bone marrow transplantation conditioning regimens. In TBI, dose escalation is difficult, because of associated normal organ toxicities. A method to deliver a more targeted dose of TBI preferentially to sites of greatest tumor burden is needed to reduce the dose to normal organs, reduce toxicities, and permit dose escalation. The purpose of th...
