Improvement of Formability in Parallel Double-Branched Tube Hydroforming Combined with Pre-Forming and Crushing Processes.

In hydroforming of parallel double-branch tubes, the material entering the branch zone is obstructed by material accumulation in the main tubes and corners, which decreases the branch height. A tube hydroforming approach is combined with pre-forming and crushing (THPC) to mitigate this problem. A larger diameter tube blank is flattened for pre-forming and then subjected to radial compression for crushing.

Safety and Efficacy of Double Lamellar Keratoplasty for Corneal Perforation.

Introduction: To assess the outcomes of double lamellar keratoplasty in the treatment of corneal perforation secondary to various keratopathies.

Methods: In this prospective non-comparative interventional case series, 15 eyes from 15 consecutive patients with corneal perforation were chosen to undergo double lamellar keratoplasty, which is characterized by two layers of lamellar grafting in the perforated area. The posterior graft was separated from a relatively healthy and thin lamellar graft of the recipient, and the anterior graft was transplanted from the donor lamellar cornea.

An Intelligent Online Drunk Driving Detection System Based on Multi-Sensor Fusion Technology.

Since drunk driving poses a significant threat to road traffic safety, there is an increasing demand for the performance and dependability of online drunk driving detection devices for automobiles. However, the majority of current detection devices only contain a single sensor, resulting in a low degree of detection accuracy, erroneous judgments, and car locking. In order to solve the problem, this study firstly designed a sensor array based on the gas diffusion model and the characteristics of a car steering wheel.

Overcoming resistance to oncolytic virus M1 by targeting PI3K-γ in tumor-associated myeloid cells.

Oncolytic viruses (OVs) have become a category of promising anticancer immunotherapeutic agents over the last decade. However, the fact that many individuals fail to respond to OVs highlights the importance of defining the barely known immunosuppressive mechanisms that lead to treatment resistance. Here we found that the immunosuppression mediated by tumor-associated myeloid cells (TAMCs) directly quenches the antitumor effect of oncolytic virus M1 (OVM).

Identification of the receptor of oncolytic virus M1 as a therapeutic predictor for multiple solid tumors.

Over the last decade, oncolytic virus (OV) therapy has shown its promising potential in tumor treatment. The fact that not every patient can benefit from it highlights the importance for defining biomarkers that help predict patients' responses. As particular self-amplifying biotherapeutics, the anti-tumor effects of OVs are highly dependent on the host factors for viral infection and replication.

Method for QCM Resonator Device Equivalent Circuit Parameter Extraction and Electrode Quality Assessment.

Quartz crystal microbalance (QCM) resonators are used in a wide range of sensors. Current QCM resonators achieve a simultaneous measurement of multiple physical quantities by analyzing lumped-element equivalent parameters, which are obtained via the introduction of external devices. This introduction of external devices will probably increase measurement error.
