Vector autoregression evidence on monetarism: another look at the robustness debate [PDF]

This paper is a case study of the use of vector autoregression (VAR) models to test economic theories. It focuses on the work of Christopher A. Sims, who in 1980 found that relationships in economic data generated by a small VAR model were inconsistent ...

Tibial tubercle osteotomy for the exposure of complex primary and revision Total Knee Arthroplasty- our 21 years of experience

Journal of Orthopaedic Reports
-: Background: Adequate exposure is often challenging in complex primary and revision Total Knee Arthroplasty (TKA). A quadriceps snip in addition to a standard approach is the most widely used approach in such cases.

Vector Autoregressions, Policy Analysis, and Directed Acyclic Graphs: An Application to the U.S. Economy [PDF]

The paper considers the use of directed acyclic graphs (DAGs), and their construction from observational data with PC-algorithm TETRAD II, in providing over-identifying restrictions on the innovations from a vector autoregression. Results from Sims’ 1986

Air Nanobubbles Enhance Viable Bacteria Counts, Abundance of Nitrifying Bacteria, and Reduce Nitrite Levels in Marine Recirculation Aquaculture Systems

Fishes
Recirculating aquaculture systems (RAS) address pollution, disease, and sustainability in commercial fish farming, but marine RAS are limited by biofilter maturation and nitrification.

Cancer Stem Cells (CSCs) in Drug Resistance and their Therapeutic Implications in Cancer Treatment

Stem Cells International, 2018
Cancer stem cells (CSCs), also known as tumor-initiating cells (TICs), are suggested to be responsible for drug resistance and cancer relapse due in part to their ability to self-renew themselves and differentiate into heterogeneous lineages of cancer ...

Simulation With MIC-SIM And MIC-SIM View [PDF]

1989 Winter Simulation Conference Proceedings, 1989
MIC-SIM is a general-purpose, discrete-event simulation system for use on IBM compatible microcomputers. It was developed as part of a doctoral dissertation in 1980 using Radio Shack computers. Microcomputers were new then and the only simulation languages available require either a mainframe or mini-computer.
