Analysis of Different R&D Co-Competition Modes of Asymmetric Duopoly Enterprises under the Uncertainty of R&D Success by Yinghua Song, Xiaoyan Sang, Zhe Wang, Hongqian Xu

“…The collaborative R&D of new products between enterprises is prone to the “free-rider effect” due to knowledge spillover. To avoid that, this paper establishes a three-stage dynamic game to explore the collaborative R&D co-competition behavior between asymmetric horizontal supplier enterprises. …”

Modeling and Stability Analysis of the Dynamics of Malaria Disease Transmission with Some Control Strategies by Alemzewde Ayalew, Yezbalem Molla, Amsalu Woldegbreal

“…The model system admits two equilibrium points: disease-free and disease-persistent equilibrium points. The analytical result of the model system revealed that the disease-free equilibrium point is both locally as well as globally asymptotically stable whenever R0<1 while the disease-persistence equilibrium point is globally asymptotically stable whenever R0>1. …”

Surgical Treatment of a Patient with a Solitary Thyroid Metastasis from Primary Sigmoid Adenocarcinoma: A Case Report and Literature Review by Kohei Yamahara, Toshiaki Moriki, Yuki Katsura, Kana Lee, Satoshi Ikegami

“…Here we describe a patient who was found to have a solitary metastasis of sigmoid cancer to the thyroid on postoperative imaging and has had prolonged disease-free survival after thyroidectomy. Our experience suggests that a low threshold of suspicion is crucial for timely diagnosis of thyroid metastasis from CRC and that resection can improve disease-free survival.…”
