A practical approach to market risk analysis and control: empirical test of the Mexican foreign exchange and stock markets
The Mexican financial markets, like many other emerging markets, are generally portrayed as illiquid, volatile, segmented and politically unpredictable. Despite all these shortcomings, portfolio investments and trading activities in emerging markets have immense rewards for markets' participants. These investment alternatives may create unique expected return opportunities and substantial ...

The Use of Imaging to Guide Treatment Decisions with Coronary Orbital Atherectomy – Case 1 of 2
Overview Dr. Brock Cookman describes this real-world case to demonstrate the importance of imaging to determine strategy and treatment in complex scenarios and how the unique dual-action mechanism of action (MOA) of the Diamondback 360® Coronary Orbital Atherectomy System sands superficial and fractures deep calcium. Patient History A 77-year-old male patient presented with ...

What is heart failure with preserved ejection fraction (HFpEF)?
Overview What is HFpEF? Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure, despite normal or near-normal LV ejection fraction (EF). Most patients with HFpEF also display normal LV volumes and an abnormal diastolic filling pattern (i.e, diastolic ...

Diagnosing heart failure with preserved ejection fraction (HFpEF)
Heart failure with preserved ejection fraction (HFpEF) has recently been recognized as the single greatest unmet need in cardiovascular medicine, overtaking heart failure with reduced ejection fraction (HFrEF) and becoming the most common form of heart failure, with a prevalence that is increasing by 1% annually.[1] Despite this, there remains no gold standard in diagnosing HFpEF. Diagnosing ...

Pile Skin Friction in Sands from Constant Normal Stiffness Tests
Many interface and sand-to-sand direct shear tests have been performed with a constant normal stiffness to investigate the effects of interface roughness, normal stiffness, soil relative density, initial normal stress, and cyclic displacement amplitude on the soilinterface response. It is demonstrated that the patterns of behavior in these tests are similar to those observed in model pile tests ...
