The union-find data structure, utilizing the “union-by-rank” and “path compression” heuristics, is one of the most efficient disjoint-set data structures known [1]. In general, union-find can be applied to any problem in which one must determine membership within a set. For instance, in class we studied its application within Kruskal’s algorithm, where it was used to efficiently detect connecte...
Distributed word representations, or word vectors, have recently been applied to many tasks in natural language processing, leading to state-of-the-art performance. A key ingredient to the successful application of these representations is to train them on very large corpora, and use these pre-trained models in downstream tasks. In this paper, we describe how we trained such high quality word r...
The induction of micronuclei was studied in mouse bone marrow treated or not with 5, 10 and 20 mg/kg b. wt. of Abana (a herbal preparation) before exposure to 0-3 Gy of γ-radiation. Whole-body irradiation of mice resulted in a dose-dependent increase in the frequency of micronuclei. Treatment of mice with various doses of Abana before exposure to different doses of γ-rays resulted in a signific...
Generating discernibility matrix consumes huge time and space .To solve this problem, A new Binary Discernibility Matrix (BDM) induced from information table is defined, The concept of Binary Conjunction Matrix(BCM) is then introduced, Finally A novel method for discernibility matrix using Ordered binary decision diagrams(OBDD) is proposed in this paper, experiment is carried to compare the sto...
Stable gastric pentadecapeptide BPC 157 is an anti-ulcer peptidergic agent, proven in clinical trials to be both safe in inflammatory bowel disease (PL-10, PLD-116, PL 14736) and wound healing, stable in human gastric juice, with no toxicity being reported. Recently, we claim that BPC 157 may be used as an antidote against NSAIDs. We focused on BPC 157 beneficial effects on stomach, duodenum, i...
The chromosome-encoded class C β-lactamase CHE-1 produced by Enterobacter cloacae exhibits a lower sensitivity to avibactam than the P99 enzyme from which it is derived by a 6-residue deletion in the H-10 helix. In the present study, we investigated the sensitivity of CHE-1 to two other β-lactamase inhibitors: LK-157 (or Lek 157), a tricyclic β-lactam, and BAL29880, a bridged monobactam. With b...
Top surface imaging (TSI) has had an interesting history. This process showed great promise in the late 1980’s and several attempts were made to introduce it to full-scale manufacturing. Unfortunately, defect density problems limited the process and it fell from favor. TSI emerged again as an important part of the EUV and 193 nm strategies in the early stages of those programs because it offere...
We print here the first English translation of a discussion of Solzhenitsyn’s Gulag, I1 by the distinguished Russian historian and intellectual dissident Roy Medvedev. Elsewhere in this issue, Peter Reddaway analyzes the exchanges of opinion going on among the Russian dissidents. We believe that the issues raised by people like Solzhenitsyn, Sakharov, and Medvedev-including their differences of...
The pentadecapeptide BPC 157 has been shown to have anti-inflammatory and wound healing effects on multiple target tissues and organs. The purpose of the present study was to investigate the effect of BPC 157 on inflammation and bone resorption in experimental periodontitis in rats. First the acute effect of BPC was tested on gingival blood flow by laser doppler flowmetry. Then periodontitis wa...
