Sympiler: Transforming Sparse Matrix Codes by Decoupling Symbolic Analysis

Sympiler is a domain-specific code generator that optimizes sparse matrix computations by decoupling the symbolic analysis phase from the numerical manipulation stage in sparse codes. The computation patterns in sparse numerical methods are guided by the input sparsity structure and the sparse algorithm itself. In many real-world simulations, the sparsity pattern changes little or not at all. Sympiler takes advantage of these properties to symbolically analyze sparse codes at compile-time and to apply inspector-guided transformations that enable applying low-level transformations to sparse codes. As a result, the Sympiler-generated code outperforms highly-optimized matrix factorization codes from commonly-used specialized libraries, obtaining average speedups over Eigen and CHOLMOD of 3.8X and 1.5X respectively.Comment: 12 page

Evidence Based Evaluation Of A Ventilator Management Clinical Practice Protocol

Nursing care and management of mechanically ventilated patients requires specific care elements to be achieved in order for optimal patient outcomes. The ventilator management policy guides nursing care for this select group of patients. The ventilator management policy of a rural community acute healthcare facility was evaluated for evidence-base and validity using the AGREE GRS rating scale. The evaluation process included interview of the director of the inpatient unit responsible for care of ventilator patients, as well as review of the most current evidence-based practice protocols. Evaluation results indicate the facility’s policy met the needs of the patients, and incorporated the most up-to-date clinical recommendations.https://scholarworks.moreheadstate.edu/celebration_posters_2021/1023/thumbnail.jp

Comparison of Red Yeast Rice Versus Statin Therapy for Dyslipidemia: A Literature Review

Statins are the first line treatment for hyperlipidemia. However, some patients do not tolerate statins. For these patients, alternative treatments such as red yeast rice may be considered. The purpose of this literature review is to compare the lipid lowering capability of red yeast rice to statins

Trump\u27s plan to dismantle national monuments comes with steep cultural and ecological costs

In the few days since President Trump issued his Executive Order on National Monuments, many legal scholars have questioned the legality of his actions under the Antiquities Act. Indeed, if the president attempts to revoke or downsize a monument designation, such actions would be on shaky, if any, legal ground. But beyond President Trump’s dubious reading of the Antiquities Act, his threats also implicate a suite of other cultural and ecological laws implemented within our national monuments. By opening a Department of Interior review of all large-scale monuments designated since 1996, Trump places at risk two decades’ worth of financial and human investment in areas such as endangered species protection, ecosystem health, recognition of tribal interests and historical protection
