In context of efforts of composing category-theoretic and logical methods in the area of knowledge representation we propose the notion of conceptory. We consider intersection/union and other constructions in conceptories as expressive alternative to category-theoretic (co)limits and show they have features similar to (pro-, in-)jections. Then we briefly discuss approaches to development of for...

This paper introduces the notion of objection-based causal networks. which resemble probabilistic causal networks ex­ cept that tht:>y are quant.ified using ob­ jections. An objection is a logical sen­ tence and denotes a condition under which a causal dependency does not exist. Objection-based causal net.works enjoy al­ most all the properties that make proba­ bilistic causal networks popular,...

Preparations of killed Corynebacterium parvum were injected into 14-day-old growing mammary adenocarcinoma cell tumors in DBA/2 mice. The tumors and the microscopic métastasesundergo rapid and lasting rejection and the animals are protected against challenges of large quantities of tumor cells of the same line. This protection can be overcome if the challenge dose is massive. Groups of tumor-b...

So far there is no unified treatment of interjections with respect to both their cognitive or emotional content and to their discourse functions. Furthermore, the various contributions interjections can make to automatic speech processing systems have not been exploited at all. An approach to the description of interjections on the basis of general constructions will be presented which accounts...

7 processing. Conventional dimensionality reduction on-board remote devices is 8 often prohibitive due to limited computational resources; on the other hand, 9 integrating random projections directly into signal acquisition offers an alternative 10 to explicit dimensionality reduction without incurring sender-side computational 11 cost. Receiver-side reconstruction of hyperspectral data from su...

background: despite advances in the medical care of renal transplant recipients which have led to an improvement in allograft survival, renal allograft rejection is still a major ob-stacle to successful organ transplantation. understanding the mechanisms contributing to allograft rejection will be of great importance for the development of efficient antirejection strategies. objective: the aim ...

jections) or as an opportunity—a delay in the onset of these conditions by, say, 5-10 years would dramatically reduce their incidence and therefore costs. Individuals have realised that if they are lucky enough to side step or survive cancer and vascular disease the next threat is neurodegeneration in its various guises. But have governments realised this? Secondary postponement of disability i...

The widespread use of I131in the diagnosis and treatment of thyroid disease in man has focused attention on the effects of this radioactive isotope in experimental animals. In 1951, Goldberg and Chaikoff described the development of benign and malignant thyroid tumors in Long-Evans rats 1.52 years after the animals had received single in jections of 400 tic. I131(7, 8). Doniach also found benig...

According to these authors, no tumors developed up to 45 days, and at that time the grafts were shown ...

The successful transplantation and serial propa gation of heterologous tumors through successive generations of latoratory animals are sought for experimental purposes. Total-body irradiation of hosts, alone or in combination with cortisone in jections, is now being used to alter the natural immunity of hosts to foreign tissues (1, 10). The discovery by Pillemer that a normal serum euglobulin, ...
