Fundamental Science and Engineering Questions in Planetary Cave Exploration

Journal of Geophysical Research: Planets, Volume 127, Issue 11, November 2022., 2022
Abstract Nearly half a century ago, two papers postulated the likelihood of lunar lava tube caves using mathematical models. Today, armed with an array of orbiting and fly‐by satellites and survey instrumentation, we have now acquired cave data across our solar system—including the identification of potential cave entrances on the Moon, Mars, and at ...

Shaping strategic arms trade controls: A multivariate approach

Kyklos, Volume 75, Issue 4, Page 646-671, November 2022., 2022
Abstract The objective of this study is to measure the stringency of strategic arms trade controls across countries and explain the variation herein. This regulatory framework is implemented by sovereign states to control the international transfer of military‐strategic items that potentially contain a security risk.

Virus-transformed pre-B cells show ordered activation but not inactivation of immunoglobulin gene rearrangement and transcription [PDF]

, 1991
Virus-transformed pre-B cells undergo ordered immunoglobulin (Ig) gene rearrangements during culture. We devised a series of highly sensitive polymerase chain reaction assays for Ig gene rearrangement and unrearranged Ig gene segment transcription to ...

Increased VH 11 and VH Q52 gene use by splenic B cells in old mice associated with oligoclonal expansions of CD5+ B cells

Mechanisms of Ageing and Development, 1998
A significant increase in the utilization of the VH gene families VH11 and Q52 was observed in LPS-stimulated splenic B lymphocytes from aged mice compared to young mice. VH gene usage was assayed by in situ DNA/RNA hybridization using VH family-specific and kappa chain probes.

Eigenvalue hypothesis for Racah matrices and HOMFLY polynomials for 3-strand knots in any symmetric and antisymmetric representations

, 2012
Character expansion expresses extended HOMFLY polynomials through traces of products of finite dimensional R- and Racah mixing matrices. We conjecture that the mixing matrices are expressed entirely in terms of the eigenvalues of the corresponding R ...
