Accelerating particle-in-cell kinetic plasma simulations via reduced-order modeling of space-charge dynamics using dynamic mode decomposition.

We present a data-driven reduced-order modeling of the space-charge dynamics for electromagnetic particle-in-cell (EMPIC) plasma simulations based on dynamic mode decomposition (DMD). The dynamics of the charged particles in kinetic plasma simulations such as EMPIC is manifested through the plasma current density defined along the edges of the spatial mesh. We showcase the efficacy of DMD in modeling the time evolution of current density through a low-dimensional feature space.

Hematological toxicities associated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Introduction: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been found to prolong survival in selected patients with peritoneal disease, but the extent of cytoreduction and chemoperfusion can result in systemic toxicities. We evaluate the incidence of perioperative hematological complications and its associated risk factors.

Methods: Retrospective analysis of a prospectively collected database of CRS-HIPEC cases between April 2001 and October 2016 was performed.

Computational Approaches Toward Integrating Quantified Self Sensing and Social Media.

The growing amount of data collected by quantified self tools and social media hold great potential for applications in personalized medicine. Whereas the first includes health-related physiological signals, the latter provides insights into a user's behavior. However, the two sources of data have largely been studied in isolation.

Morbidity and mortality of elderly patients following cytoreductive surgery and Hyperthermic Intraperitoneal Chemotherapy (HIPEC).

Aim: Cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is known to improve survival in selected patients with peritoneal metastasis. However, there is limited data supporting the role of CRS and HIPEC in elderly patients (≥65 years old).

Methods: A retrospective review of a prospectively maintained database of patients who underwent CRS-HIPEC between April 2001 and July 2015 from a single institution was performed.

Surgical Management of Metastatic Colorectal Cancer: A Single-Centre Experience on Oncological Outcomes of Pulmonary Resection vs Cytoreductive Surgery and HIPEC.

Purpose: Metastasectomy is accepted as standard of care for selected patients with colorectal pulmonary metastases (CLM); however, the role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for colorectal peritoneal metastases (CPM) is not universally accepted. We aim to compare oncological outcomes of patients with CLM and CPM after pulmonary resection and CRS-HIPEC, respectively, by comparing overall survival (OS) and disease-free survival (DFS).

Methods: A retrospective review of 49 CLM patients who underwent pulmonary resection, and 52 CPM patients who underwent CRS-HIPEC in a single institution from January 2003 to March 2015, was performed.

201 consecutive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) procedures in a single Asian tertiary centre.

Introduction: Peritoneal carcinomatosis (PC) is increasingly being treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). We provide a review of a high-volume Asian institute's experience and survival outcomes with this procedure.

Methods: Data were prospectively collected from 201 consecutive CRS and HIPEC procedures performed in a single institution between April 2001 and November 2015.

Is multivisceral resection in locally advanced gastrointestinal stromal tumours an acceptable strategy?

Background: Gastrointestinal stromal tumours (GISTs) represent the most common mesenchymal tumour of the gastrointestinal tract. Although the efficacy of targeted therapy cannot be over-emphasized, surgery remains the only curative primary treatment for patients with localized disease. The median size of GIST at diagnosis is approximately 5-7 cm; however, it is not uncommon for tumours to be as large as 30-40 cm and involving multiple viscera.

Lactic acid fermentation by cells immobilised on various porous cellulosic materials and their alginate/poly-lactic acid composites.

Porous delignified cellulose (or tubular cellulose, abbr. TC) from Indian Mango (Mangifera indica) and Sal (Shorea robusta) wood and Rice husk, and TC/Ca-alginate/polylactic acid composites, were used as Lactobacillus bulgaricus immobilisation carriers leading to improvements in lactic acid fermentation of cheese whey and synthetic lactose media, compared to free cells. Specifically, shorter fermentation rates, higher lactic acid yields (g/g sugar utilised) and productivities (g/Ld), and higher amounts of volatile by-products were achieved, while no significant differences were observed on the performance of the different immobilised biocatalysts.
