On a single-input-single-out (SISO) interference channel (IC), conventional non-cooperative strategies encourage players selfishly maximizing their transmit data rates, neglecting the deficit of performance caused by and to other players. In the case of proper complex Gaussian noise, the maximum entropy theorem shows that the best-response strategy is to transmit with proper signals (symmetric ...

Objective: Oblique lateral lumbar interbody fusion (OLIF) surgery has been increasingly proposed a preferred minimally invasive approach for degenerative pathology. We aimed to report cases with vertebrae coronal fracture (VCF) following OLIF combined anterolateral single-rod screw fixation (OLIF-AF). Methods: A retrospective review was performed on all patients who underwent OLIF-AF between Oc...

Most patients with ovarian cancer undergo surgery at some point during the course of their treatment. A primary operation may be undertaken for the purpose of confirming the diagnosis, staging, and debulking. Numerous publications have documented the importance of proper staging in ovarian cancer, which determines the treatment plan — including whether chemotherapy is indicated — and therefore ...

Non-circular or improper Gaussian signaling has proven beneficial in several interference-limited wireless networks. However, all implementable coding schemes are based on finite discrete constellations rather than Gaussian signals. In this paper, we propose a new family of improper constellations generated by widely linear processing of a square M-QAM (quadrature amplitude modulation) signal. ...

BACKGROUND Neural tube defects (NTDs) are some of the most common congenital anomalies. Proper folic acid supplementation is a dominant risk factor, which has been shown to decrease the incidence of NTDs. In Canada, the incidence of neuroblastoma has presented a considerable decrease of 60% as a result of enrichment cereal grain flours with synthetic folic acid. The aim of this study was to inv...

When physicians' conflicts of interest arise from ties with drug firms, we should shift our focus to the pharmaceutical industry and improper dependencies that cause institutional corruption. This article analyzes eight forms of improper dependencies on pharma and proposes reforms.
