Rewriting History in Integrable Stochastic Particle Systems.

Many integrable stochastic particle systems in one space dimension (such as TASEP-Totally Asymmetric Simple Exclusion Process-and its -deformation, the -TASEP) remain integrable if we equip each particle with its own speed parameter. In this work, we present intertwining relations between Markov transition operators of particle systems which differ by a permutation of the speed parameters. These relations generalize our previous works (Petrov and Saenz in Probab Theory Relat Fields 182:481-530, 2022), (Petrov in SIGMA 17(021):34, 2021), but here we employ a novel approach based on the Yang-Baxter equation for the higher spin stochastic six vertex model.

[The Russian consensus on the treatment of intrahepatic cholangiocarcinoma].

The Russian consensus on the treatment of intrahepatic cholangiocarcinoma was prepared by the group of experts consisting of surgeons, interventional radiologists, radiation therapists and oncologists. The purposes of this consensus are clarification and consolidation of opinions of multidisciplinary team on the following issues of management of patients with intrahepatic cholangiocarcinoma: indications for surgical treatment, features of therapeutic tactics for mechanical jaundice, technical aspects of liver resection, prevention of post-resection liver failure, indications for liver resection using transplantation technologies, laparoscopic and robot-assisted liver resection, perioperative systemic chemotherapy, local non-resection/non-radiotherapy methods of treatment, radiotherapy, follow-up and choice of treatment for recurrence.

The life-saving benefit of dexamethasone in severe COVID-19 is linked to a reversal of monocyte dysregulation.

Dexamethasone is a life-saving treatment for severe COVID-19, yet its mechanism of action is unknown, and many patients deteriorate or die despite timely treatment initiation. Here, we identify dexamethasone treatment-induced cellular and molecular changes associated with improved survival in COVID-19 patients. We observed a reversal of transcriptional hallmark signatures in monocytes associated with severe COVID-19 and the induction of a monocyte substate characterized by the expression of glucocorticoid-response genes.

Effect of Aging on Tensile and Chemical Properties of Polylactic Acid and Polylactic Acid-Like Polymer Materials for Additive Manufacturing.

Additive manufacturing, with its fast development and application of polymeric materials, led to the wide utilization of polylactic acid (PLA) materials. As a biodegradable and biocompatible aliphatic polyester, produced from renewable sources, PLA is widely used in different sectors, from industry to medicine and science. The aim of this research is to determine the differences between two forms of the PLA material, i.

A Comprehensive Mechanical Examination of ABS and ABS-like Polymers Additively Manufactured by Material Extrusion and Vat Photopolymerization Processes.

Additive manufacturing technologies have developed rapidly in recent decades, pushing the limits of known manufacturing processes. The need to study the properties of the different materials used for these processes comprehensively and in detail has become a primary goal in order to get the best out of the manufacturing itself. The widely used thermoplastic polymer material acrylonitrile butadiene styrene (ABS) was selected in the form of both filaments and ABS-like resins to investigate and compare the mechanical properties through a series of different tests.
