Asymptotic behavior of solutions to the conformal quotient equation
We classify all radial admissible solutions to the conformal quotient equation on the punctured Euclidean space and prove that an admissible solution to the conformal quotient equation with an isolated singular point is asymptotic to a radial solution. We also provide an alternative proof to obtain higher order expansion of solutions using analysis of the linearized operators. This dissertation is based on a preprint of the author [89].Ph.

Image_1_5-FU-Induced Upregulation of Exosomal PD-L1 Causes Immunosuppression in Advanced Gastric Cancer Patients.TIF
Although the cytotoxic chemotherapeutic agent 5-fluorouracil (5-FU) is generally considered to directly kill cancer cells and exert immunostimulatory effects in advanced gastric cancer, accumulating evidence indicates that it upregulates the expression of PD-L1, a representative immune checkpoint blockade molecule involved in negative regulation of the immune response. It was reported that exosomes could transfer functional PD-L1 locally and distantly to suppress the antitumor immune response. However, whether 5-FU alters the expression of exosomal PD-L1 and induces immunosuppression in gastric cancer remains unclear. Herein, we found that 5-FU increased gastric cancer-derived exosomal PD-L1. Importantly, compared with baseline levels, circulating exosomal PD-L1 was significantly upregulated in 21 stage III–IV gastric cancer patients after two, four, and six repeated cycles of fluoropyrimidine treatment (P = 0.009, P = 0.047, and P = 0.023, respectively), accompanied by decreased amounts of IFN-γ, TNF-α, IL-2, IL-6, and GM-CSF (P = 0.014, P = 0.004, P = 0.009, P = 0.031, and P = 0.014, respectively). Additionally, circulating exosomal PD-L1 was increased more significantly in clinical non-responders compared with responders (P = 0.018). Furthermore, exosomal PD-L1 induced apoptosis in Jurkat T cells and inhibited T cell activation in PBMCs, which could be partly reversed by nivolumab. These results suggested that 5-FU-induced upregulation of exosomal PD-L1 causes systemic immunosuppression in advanced gastric cancer following multiple cycles of chemotherapy, especially after two cycles.</p

Fault location in a marine low speed two stroke diesel engine using the characteristic curves method
When a malfunction occurs in a marine main engine system, the impact of the anomaly will
propagate through the system, affecting the performance of all relevant components in the system. The
phenomenon of fault propagation in the system caused by induced factors can interfere with fault
localization, making the latter a difficult task to solve. This paper aims at showing how the
“characteristic curves method” is able to properly locate malfunctions also when more malfunctions
appear simultaneously. To this end, starting from the working principle of each component of a real
marine diesel engine system, comprehensive and reasonable thermal performance parameters are
chosen to describe their characteristic curves and include them in a one-dimensional thermodynamic
model. In particular, the model of a low-speed two stroke MAN 6S50 MC-C8.1 diesel engine is built
using the AVL Boost software and obtaining errors lower than 5% between simulated values and test
bench data. The behavior of the engine is simulated considering eight multi-fault concomitant
phenomena. On this basis, the fault diagnosis method proposed in this paper is verified. The results
show that this diagnosis method can effectively isolate the fault propagation phenomenon in the system
and quantify the additional irreversibility caused by the Induced factors. The fault diagnosis index
proposed in this paper can quickly locate the abnormal components
