A major credit shock can induce large intra-day variation margin payments between counterparties in derivatives markets, which may force some participants to default on their payments. These payment shortfalls become amplified as they cascade through the network of exposures. Using detailed DTCC data we model the full network of exposures, the shock-induced payments, the initial margin collecte...

An approach to extend classical robustness margins to linear parameter varying (LPV) systems is presented. LPV systems are often used to model aircraft dynamics that are highly dependent on the operating conditions such as altitude and airspeed. Classical gain and phase margins are evaluated in the frequency domain and therefore cannot be applied to LPV systems. The proposed approach is based o...

Anterior resection with total mesorectal excision is the standard method of rectal cancer resection. However, this procedure remains technically difficult in mid and low rectal cancer. A robotic transanal proctectomy with total mesorectal excision and laparoscopic assistance is reported in a 57 year old male with BMI 32 kg/m2 and rectal adenocarcinoma T2N1M0 at 5 cm from the dentate line. Opera...

In this brief, the margin of stability of two-dimensional (2D) discrete systems is considered. A new method to compute the stability margin of 2-D continuous systems is provided. Illustrative examples are also included.

......Microprocessors must operate reliably across a wide range of environmental conditions and workloads. Selecting an operating voltage high enough to account for worst-case conditions without violating power budgets is a growing challenge. Extra margin in the form of voltage guardband must be included to guarantee proper circuit timing during worst-case voltage droop events, in addition to c...

BACKGROUND Hospitals that have robust financial performance may have improved publicly reported outcomes. OBJECTIVES To assess the relationship between hospital financial performance and publicly reported outcomes of care, and to assess whether improved outcome metrics affect subsequent hospital financial performance. DESIGN Observational cohort study. SETTING AND PATIENTS Hospital financ...

Companies in different industries have their own operation situation. Then, if companies a same industry are facing some general problems or advantages, will financial performance of an be distinguishable from industry? Through using discriminant analysis, the paper gives out outcome differentiating two based on combination ratios. Each is represented by number that listed and successful. Five ...

The paper’s prime objective is to understand the impact of Shareholder activism on firm performance. This study conducted in a unique setup where traditional activist investors such as pension funds and hedge are not present. However, cases increasing yearly an emerging economy like India. We have created comprehensive shareholder index (sha index) using multiple activisms corporate governance ...

The paper extends a mean value model of a parallel turbocharged internal combustion engine with a crank angle resolved cylinder model. The result is a 0D engine model that includes the pulsating flow from the intake and exhaust valves. The model captures variations in turbo speed and pressure, and therefore variations in the compressor operating point, during an engine cycle. The model is used ...
