Functional status of heart transplant recipients predicts survival

Taylor B. Shaw, David Blitzer, Kristen T. Carter, Seth Lirette, more

Clinical Transplantation > 36 > 8 > n/a - n/a

Introduction Recipient functional status prior to transplantation can significantly impact post‐transplant survival. Methods The United Network for Organ Sharing database was queried for adult heart transplants including data on functional capacity and from February 1, 2005 to March 1, 2021; there were 32 875 cases included. The four functional categories studied were based on adult daily activities...

Ischemic time and patient outcomes after the 2018 UNOS donor heart allocation system change

Umar Siddiqi, Seth Lirette, Ryan Hoang, Jennifer Cruz, more

Journal of Cardiac Surgery > 37 > 9 > 2685 - 2690

Background The allocation system for heart donors in the United States changed on October 18, 2018. The typical distance from donor hospitals to recipient hospitals has increased as has the ischemic time. We investigated patient outcomes with the new allocation system and the differential effects of ischemic time under both the old and new allocation schemas. Methods The United Network for Organ...

Screen History: The Haeff Memory and Graphics Tube

B. Jack Copeland, Andre A. Haeff, Peter Gough, Cameron Wright

IEEE Annals of the History of Computing > 2017 > 39 > 1 > 9 - 28

Haeff-type tubes formed the high-speed memory of Whirlwind I but had their greatest impact in graphics and display technology, remaining in widespread use until the 1980s. Haeff seems to have been the first to store and display graphics and text on an electronic screen for an unlimited period, in 1947.

Hypercomputation in the Chinese Room

B. Jack Copeland

Lecture Notes in Computer Science > Unconventional Models of Computation > Invited Papers > 15-26

I rehearse a number of objections to John Searle’s famous Chinese room argument. One is the ’hypercomputational objection’ (Copeland 2002a). Hypercomputation is the computation of functions that cannot be computed in the sense of (Turing (1936)); the term originates in (Copeland and Proudfoot (1999)). I defend my hypercomputa tional objection to the Chinese room argument from a response recently developed...

Turing’s Test

Jack Copeland, Diane Proudfoot

Parsing the Turing Test > The Ongoing Philosophical Debate > 119-138

We set the Turing Test in the historical context of the development of machine intelligence, describe the different forms of the test and its rationale, and counter common misinterpretations and objections. Recently published material by Turing casts fresh light on his thinking.

The Computer, Artificial Intelligence, and the Turing Test

B. Jack Copeland, Diane Proudfoot

Alan Turing: Life and Legacy of a Great Thinker > Artificial Intelligence and the Turing Test > 317-351

Summary We discuss, first, Turing’s role in the development of the computer; second, the early history of Artificial Intelligence (to 1956); and third, Turing’s famous imitation game, now universally known as the Turing test, which he proposed in cameo form in 1948 and then more fully in 1950 and 1952. Various objections have been raised to Turing’s test: we describe some of the most prominent and...

Heterotopic Heart Transplantation: Technical Considerations

Jack Copeland, Hannah Copeland

Operative Techniques in Thoracic and Cardiovascular Surgery > 2016 > 21 > 3 > 269-280

Heterotopic heart transplantation is seldom used but may be due a renaissance. In a left assist configuration, heterotopic heart transplantation could expand the pool of heart donors and also enable transplantation in groups of patients who are currently not eligible for a heart transplant. With the biologic left ventricular assist (bio-LVA) concept, much as with a left ventricular assist device,...

Prior, translational semantics, and the Barcan formula

B. Jack Copeland

Synthese > 2016 > 193 > 11 > 3507-3519

The revolution in semantics in the late 1960s and 1970s overturned an earlier competing paradigm, ‘translational’ semantics. I revive and defend Prior’s translational semantics for modals and tense-modals. I also show how to extend Prior’s propositional modal semantics to quantificational modal logic, and use the resulting semantics to formalize Prior’s own counterexample to the Barcan Formula.

The true history of the traveling wave tube

Jack Copeland, Andre A. Haeff

IEEE Spectrum > 2015 > 52 > 9 > 38 - 43

An intense-looking young man stepped out of his engineering lab at Caltech to watch what was happening. In the university’s nearby high-voltage laboratory, gigantic bolts of electricity were leaping eerily from outlandish equipment. It was 1931, and a Hollywood crew was filming the spark-filled special effects for the creation scene in Boris Karloff’s first Frankenstein movie. The serious-minded young...

Andrew V. Haeff: Enigma of the Tube Era and Forgotten Computing Pioneer

Jack Copeland, Andre A. Haeff

IEEE Annals of the History of Computing > 2015 > 37 > 1 > 67 - 74

Prolific, yet neglected inventor Andrew Vasily Haeff (1905-1990) made numerous contributions to vacuum tube art, including the traveling wave tube, the inductive-output tube, the electron-wave tube (or "double-stream" amplifier), the resistive wall tube, and many others. Haeff's contributions to computing history include his pioneering computer monitor technology, his high-speed electrostatic...

Coarctation of the thoracic aorta masquerading as bilateral aorto-iliac stenosis

Khalid Bin Thani, Khushboo Kaushal, Denise Barnard, Jack Copeland, more

Journal of Cardiology Cases > 2011 > 4 > 3 > e172-e175

We present a case with coarctation of the aorta (CoA) with lifestyle limiting claudication and lower extremity weakness, successfully treated with surgical correction. The presented case discusses the diagnostic challenges associated with identifying CoA in patients with claudication.

The Manchester Computer: A Revised History Part 1: The Memory

B Jack Copeland

IEEE Annals of the History of Computing > 2011 > 33 > 1 > 4 - 21

The Manchester Baby, built by F.C. Williams and Tom Kilburn and operational in June 1948, was the first stored-program electronic computer. The Williams-Kilburn tube memory, pioneered in the Baby, was subsequently adopted in many first-generation computers, including the Princeton IAS machine and the IBM 701. Part 1 of this article provides an overview of the Manchester project and its personnel and...

The Manchester Computer: A Revised History Part 2: The Baby Computer

B Jack Copeland

IEEE Annals of the History of Computing > 2011 > 33 > 1 > 22 - 37

The logical design of the 1948 Manchester Baby was virtually identical to a 1946 Princeton design. However, thanks to F.C. Williams' and Tom Kilburn's groundbreaking cathode ray tube (CRT) memory and their innovative engineering, the universal electronic digital computer made its world debut in Manchester. This article reassesses the place of Williams and Kilburn in the history of computing.

Do Accelerating Turing Machines Compute the Uncomputable?

B. Jack Copeland, Oron Shagrir

Minds and Machines > 2011 > 21 > 2 > 221-239

Accelerating Turing machines have attracted much attention in the last decade or so. They have been described as “the work-horse of hypercomputation” (Potgieter and Rosinger 2010: 853). But do they really compute beyond the “Turing limit”—e.g., compute the halting function? We argue that the answer depends on what you mean by an accelerating Turing machine, on what you mean by computation, and even...

Infant Myocardial Recovery With Device and Surgical Repair

Jack Copeland, Hannah Zimmerman

The Annals of Thoracic Surgery > 2011 > 91 > 1 > e1-e2

A 4-month-old female infant (weight, 6.17 kg; height, 65 cm) presenting with tachypnea and tachycardia, and a left ventricular ejection fraction of 10%, deteriorated on increasing inotropic therapy and mechanical ventilation. Implantation of a centrifugal left ventricular assist device and institution of maximal medical heart failure therapy led to reverse remodeling and discontinuation of device...
