Psychiatric Study of one Thousand Alcoholic Patients

CSF electrophoresis in one thousand patients.

Agarose and/or cellulose acetate electrophoresis was performed on the CSF of one thousand patients. In patients with clinically definite multiple sclerosis (MS) (N = 267) 92.8% had oligoclonal banding (O.B.). In patients with possible MS (N = 283) O.B. was present in 31.1%. In patients with other neurological diseases (N = 450) O.B. was present in 8% (N = 36). Nineteen non-MS patients with posi...

"One-thousand one... one-thousand two...": chronometric counting violates the scalar property in interval timing.

Weber's law applied to interval timing is called the scalar property. A hallmark of timing in the seconds-to-minutes range, the scalar property is characterized by proportionality between the standard deviation of a response distribution and the duration being timed. In this temporal reproduction study, we assessed whether the scalar property was upheld when participants chronometrically counte...

The Thousand-and-One Cryptographers

Chaum’s Dining Cryptographers protocol crystallises the essentials of security just as other famous diners once captured deadlock and livelock: it is a benchmark for security models and their associated verification methods. Here we give a correctness proof of the Cryptographers in a new style, one in which stepwise refinement plays a prominent role. Furthermore, our proof applies to arbitraril...

Fifteen-to twenty-year study of one thousand patients undergoing closed mitral valvuloplasty.

a report of the status of the patients at each year of follow-up, a detailed analysis has been made of the factors influencing results of surgery 15 years after operation. The most important factor adversely influencing long-term results is significant mitral valve calcification. This is true regardless of age, sex, preoperative status, concomitant mitral insufficiency or minor degrees of aorti...
