Transitive factorizations of permutations and geometry [PDF]
, 2014 We give an account of our work on transitive factorizations of permutations. The work has had impact upon other areas of mathematics such as the enumeration of graph embeddings, random matrices, branched covers, and the moduli spaces of curves.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma occurring most commonly in adolescence and young adulthood. Methods We present the clinical characteristics, treatments, and outcomes of patients with newly diagnosed ASPS enrolled on the Children's Oncology Group study ARST0332.

Class Forcing in Class Theory [PDF]
, 2017 In this article we adapt the existing account of class-forcing over a ZFC model to a model $(M,\mathcal{C})$ of Morse-Kelley class theory. We give a rigorous definition of class-forcing in such a model and show that the Definability Lemma (and the Truth Lemma) can be proven without restricting the notion of forcing.

Administering Suspect Classes [PDF]
, 2017 It has been over forty years since the Supreme Court declared a class suspect under the Equal Protection Clause. In that time, the Court has denied suspect-class status—and the special judicial protections associated with it—to the elderly, the disabled,

Excited Young diagrams and equivariant Schubert calculus [PDF]
, 2007 We describe the torus-equivariant cohomology ring of isotropic Grassmannians by using a localization map to the torus fixed points. We present two types of formulas for equivariant Schubert classes of these homogeneous spaces.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Nordic Studies in Science Education, 2013 Chinese abstract:概述学校教学最重要目的之一是赋予每个孩子同等的教育. 尽管如此, 学校再创造了社会差异. 先前的研究表明,学生的低下社会经济情况背景与自然学科成绩低下有一定联系. 这样, 不少学生在未来就被排斥在社会高端学科的教育和职业之外. 本篇论文在Bourdieu和Bernstein的理论基础上, 以自然学科课堂的社会阶级为中心, 旨在对小 学生所受的教育存在不等现象提供更多方位描述和更深层的分析. 在人种民族学的启发下, 本论文的数据取自瑞典义务小学八年级物理教室里的观察, 记录, 采访和统计调查. 1. 对教室里现象的描述和分析揭示了知识难度的下降.

Structurally Stable Homoclinic Classes [PDF]
, 2014 In this paper we study structurally stable homoclinic classes. In a natural way, the structural stability for an individual homoclinic class is defined through the continuation of periodic points.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
