Collaboration environments impose high demands on humans and artificial systems. Especially during critical tasks team members, including humans, artificial systems and other (sub-) teams, require support to guarantee their continued effectiveness. Effectiveness of individuals and teams is an important ingredient for organizational effectiveness, managerial decision quality, as well as for main...

Background. One or more brief episodes of coronary artery occlusion protect or "precondition" the myocardium perfused by that artery from a subsequent episode of sustained ischemia. We sought to determine whether ischemic preconditioning protects only those myocytes subjected to brief coronary occlusion or whether brief occlusions in one vascular bed also limit infarct size andfor attenuate con...

The effects of brief and sustained pharmacologic alpha-adrenergic stimulation on the coronary arterial circulation were compared in awake pigs. Phenylephrine was administered into the left anterior descending coronary artery (LAD) either as a bolus (eight pigs) or as a 15-minute infusion (eight pigs), with myocardial blood flow measured by the radioactive microsphere technique. Flow in the dist...

During a recent 4-year period, 381 patients were admitted with injuries sustained from falls. Equal numbers of patients were less than and greater than 50 years of age and included 53 children (less than or equal to 16 years) and 214 elderly (greater than or equal to 55 years). Falls from heights occurred predominantly in young males (mean age 34.2 years), were most commonly job or recreation r...

Sustained-release corticosteroid treatment has shown to be a promising strategy for macular edema due to retinovascular disease (i.e., diabetes and retinal vein occlusion) and for the treatment of noninfectious posterior uveitis. Clinicians now have the option of three sustained-release corticosteroid implants: Ozurdex (Allergan Inc., Irvine, CA) which releases dexamethasone and two devices tha...

Memory-hard functions (MHF) are functions whose evaluation cost is dominated by memory cost. MHFs are egalitarian, in the sense that evaluating them on dedicated hardware (like FPGAs or ASICs) is not much cheaper than on off-the-shelf hardware (like x86 CPUs). MHFs have interesting cryptographic applications, most notably to password hashing and securing blockchains. Alwen and Serbinenko [STOC’...

Antirenin to hog renin produced in the dog neutralizes the acute pressor effect of dog as well as hog renin. A course of intramuscular injections of hog renin in chronic renal hypertensive dogs produces an antihypertensive effect which is correlated with the antirenin titers of the plasma. Passive transfer of high titer homologous antiserum to hog renin produces an antihypertensive effect in ch...
