Dust Polarization toward Embedded Protostars in Ophiuchus with ALMA. I. VLA 1623
Sadavoy, Sarah I.,Myers, Philip C.,Stephens, Ian W.,Tobin, John,Commerç,on, Benoî,t,Henning, Thomas,Looney, Leslie,Kwon, Woojin,Segura-Cox, Dominique,Harris, Robert American Astronomical Society 2018 The Astrophysical journal Vol.859 No.2
<P>We present high-resolution (similar to 30 au) ALMA Band 6 dust polarization observations of VLA 1623. The VLA 1623 data resolve compact similar to 40 au inner disks around the two protobinary sources, VLA 1623-A and VLA 1623-B, and also an extended similar to 180 au ring of dust around VLA 1623-A. This dust ring was previously identified as a large disk in lower-resolution observations. We detect highly structured dust polarization toward the inner disks and the extended ring with typical polarization fractions similar to 1.7% and similar to 2.4%, respectively. The two components also show distinct polarization morphologies. The inner disks have uniform polarization angles aligned with their minor axes. This morphology is consistent with expectations from dust scattering. By contrast, the extended dust ring has an azimuthal polarization morphology not previously seen in lower-resolution observations. We find that our observations are well-fit by a static, oblate spheroid model with a flux-frozen, poloidal magnetic field. We propose that the polarization traces magnetic grain alignment likely from flux freezing on large scales and magnetic diffusion on small scales. Alternatively, the azimuthal polarization may be attributed to grain alignment by the anisotropic radiation field. If the grains are radiatively aligned, then our observations indicate that large (similar to 100 mu m) dust grains grow quickly at large angular extents. Finally, we identify significant proper motion of VLA 1623 using our observations and those in the literature. This result indicates that the proper motion of nearby systems must be corrected for when combining ALMA data from different epochs.</P>

Study Design: This study is a retrospective cohort study.Purpose: This study aims to determine whether preoperative neuroforaminal stenosis (FS) severity is associated with motor function patient-reported outcome measures (PROMs) following anterior cervical discectomy and fusion (ACDF).Overview of Literature: Cervical FS can significantly contribute to patient symptoms. While magnetic resonance imaging (MRI) has been used to classify FS, there has been limited research into the impact of FS severity on patient outcomes.Methods: Patients undergoing primary, elective 1–3 level ACDF for radiculopathy at a single academic center between 2015 and 2021 were identified retrospectively. Cervical FS was evaluated using axial T2-weighted MRI images via a validated grading scale. The maximum degree of stenosis was used for multilevel disease. Motor symptoms were classified using encounters at their final preoperative and first postoperative visits, with examinations ≤3/5 indicating weakness. PROMs were obtained preoperatively and at 1-year follow-up. Bivariate analysis was used to compare outcomes based on stenosis severity, followed by multivariable analysis.Results: This study included 354 patients, 157 with moderate stenosis and 197 with severe stenosis. Overall, 58 patients (16.4%) presented with upper extremity weakness ≤3/5. A similar number of patients in both groups presented with baseline motor weakness (13.5% vs. 16.55, <i>p</i> =0.431). Postoperatively, 97.1% and 87.0% of patients with severe and moderate FS, respectively, experienced full motor recovery (<i>p</i> =0.134). At 1-year, patients with severe neuroforaminal stenosis presented with significantly worse 12-item Short Form Survey Physical Component Score (PCS-12) (33.3 vs. 37.3, <i>p</i> =0.049) but demonstrated a greater magnitude of improvement (Δ PCS-12: 5.43 vs. 0.87, <i>p</i> =0.048). Worse stenosis was independently associated with greater ΔPCS-12 at 1-year (β =5.59, <i>p</i> =0.022).Conclusions: Patients with severe FS presented with worse preoperative physical health. While ACDF improved outcomes and conferred similar motor recovery in all patients, those with severe FS reported much better improvement in physical function.

Study Design: Retrospective cohort study.Purpose: Our goal was to determine which radiographic images are most essential for degenerative spondylolisthesis (DS) classification and instability detection.Overview of Literature: The heterogeneity in DS requires multiple imaging views to evaluate vertebral translation, disc space, slip angle, and instability. However, there are several restrictions on frequently used imaging perspectives such as flexion-extension and upright radiography.Methods: We assessed baseline neutral upright, standing flexion, seated lateral radiographs, and magnetic resonance imaging (MRI) for patients identified with spondylolisthesis from January 2021 to May 2022 by a single spine surgeon. DS was classified by Meyerding and Clinical and Radiographic Degenerative Spondylolisthesis classifications. A difference of >10° or >8% between views, respectively, was used to characterize angular and translational instability. Analysis of variance and paired chi-square tests were utilized to compare modalities.Results: A total of 136 patients were included. Seated lateral and standing flexion radiographs showed the greatest slip percentage (16.0% and 16.7%), while MRI revealed the lowest (12.2%, <i>p</i> <0.001). Standing flexion and lateral radiographs when seated produced more kyphosis (4.66° and 4.97°, respectively) than neutral upright and MRI (7.19° and 7.20°, <i>p</i> <0.001). Seated lateral performed similarly to standing flexion in detecting all measurement parameters and categorizing DS (all <i>p</i> >0.05). Translational instability was shown to be more prevalent when associated with seated lateral or standing flexion than when combined with neutral upright (31.5% vs. 20.2%, <i>p</i> =0.041; and 28.1% vs. 14.6%, <i>p</i> =0.014, respectively). There were no differences between seated lateral or standing flexion in the detection of instability (all <i>p</i> >0.20).Conclusions: Seated lateral radiographs are appropriate alternatives for standing flexion radiographs. Films taken when standing up straight do not offer any more information for DS detection. Rather than standing flexion-extension radiographs, instability can be detected using an MRI, which is often performed preoperatively, paired with a single seated lateral radiograph.
Combatting the Global Empire: Exploring a Theology of Resistance and Subversion
I. John Mohan Razu 한국민중신학회 2007 Madang: Journal of Contextual Theology Vol.8 No.-
The corollary of the global empire is the natural alignment of the ideology of neo-liberalism. Hence, any discourse on empire building will have to take into consideration the convergence of socio-economic, politico-cultural and religious dimensions. Through an analysis I have pointed out the inter-connections between empire and capital, neo-conservatism and neo-liberalism of the present era of empire building. Though these two are separate categories, in the process they are connected and thus reinforce and consolidate their logic of control, expansion, and domination. In a context like this, what ought to be the response of Dalit and Minjung theologians? This article shows that convergence arguments and discourses from the proponents of empire-capital is contested by the writer and apparently proposes a counter-veiling subaltern theological convergence that could perhaps become one of the prescriptive theological modes. Further, this paper interrogates and critiques the empire-building project of the United States and its allies which should be resisted by all means in view of the deeply engrained universal principles premised on sovereignty, mutual respect, co-habitation, inclusivity, egality analysis, and global ethical principles. In this paper, it is apparent that interrogation and examination of the convergence arguments in the debate of empire building faces strong resistance from the deeply engrained Biblical and theological principles of subversion and resistance rooted in praxis as a countervailing theology to the growing phenomenon of empire-capital expansion.
