We define a stratification of Deligne--Lusztig varieties and their parahoric analogues which we call the Drinfeld stratification. In the setting of inner forms of GLn, we study the cohomology of these strata and give a complete description of the unique closed stratum. We state precise conjectures on the representation-theoretic behavior of the stratification. We expect this stratification to play a central role in the investigation of geometric constructions of representations of $p$-adic groups.

背景:近年, 唾液腺腫瘍の術前診断において穿刺吸引細胞診は, その正診率の高さから広く受け入れられており, 重要性がますます高まってきている. しかし, まれな疾患に関しては依然として満足できる様な正診率は得られていないのが現状であろうと思われる. 現在, 唾液腺腫瘍の組織診ならびに細胞診は, WHO分類 (第2版) に基づいて行われているが, そこには多数の頻度的にかなり低い疾患が含まれている. 一搬的な唾液腺腫瘍の細胞診に関する解説書は多くみられるが, この様なまれな疾患についてはほとんど取り扱われていない.目的:本稿では, まれな唾液腺腫瘍の内, 組織学的あるいは細胞学的に特徴のある疾患 (良性では, 基底細胞腺腫, 筋上皮腫, オンコサイトーマ, 悪性では, 基底細胞腺癌, 悪性筋上皮腫, 上皮一筋上皮性癌, 唾液導管癌, 未分化癌) について, 自験例を提示しながらその疾患概念と臨床的特徴, 組織像, および細胞像の総説的な解説を行った.結論:実際の唾液腺腫瘍の細胞診を行うにあたっては, 個々の疾患の特徴となる臨床像と組織像を把握し, 細胞像からどこまで組織像を類推できるかが重要な診断の鍵になると思われる.

b r t w u r t i c As with other cardiovascular diseases, advances in our understanding of the pathophysiology of acute coronary syndrome (ACS) have resulted in the use of new biomarkers (measurable plasma molecules) that reflect the different mechanisms that underlie the condition. These biomarkers are valuable tools that are increasingly used not only for early diagnosis but for shortand long-term prognostic stratification. A wide range of biomarkers are now available in ACS, including those that reflect vascular inflammation due to atherosclerotic disease (high-sensitivity C-reactive protein [CRP]), markers of protease activity associated with progression of atherosclerosis and plaque destabilization (cystatin C), and those indicating myocardial injury (troponin and ST2), renal damage (cystatin C, NGAL, glomerular filtration rate), or ventricular dysfunction (neurohormonal peptides

In this paper we compare the $\mathbb J$-stratification (or the semi-module stratification) and the Ekedahl-Oort stratification of affine Deligne-Lusztig varieties in the superbasic case. In particular, we classify the cases where the $\mathbb J$-stratification gives a refinement of the Ekedahl-Oort stratification, which include many interesting cases such that the affine Deligne-Lusztig variety admits a simple geometric structure.
