금세기초부터 갖가지 물질이 vaccine에 가해졌으며, 일정한 처방이 vaccine을 더욱 유효하게 만들기 위해서 고안되고 있다. 많은 선택권에도 불구하고 다만 aluminium 염(鹽)만이 사람용 vaccine adjuvant(면역응답강화물질)로 받아들여지고 있으며, 수의(동물)용 vaccine도 크게 aluminium 염의 사용에 의존하고 있다. 현재 많은 새로운 vaccine들이 개발되고 있으나 vaccine당 구성분의 수를 증가시키고 또한 vaccine 과정에서 요구되는 dose 수를 줄이는 vaccine 접종 schedule을 단순화시키고져 하는 욕구가 대두되고 있다. 이제 더욱 유효한 adjuvant들이 이 욕구를 성취시키기 위해서 요구되는 것이다.

<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>
