A 72-year-old man was noted to have an abdominal mass during a health check-up. Computed tomography showed a large cyst-like structure in the right subhepatic space (white arrowheads) that had continuity with the proximal and distal ileal loops. The wall of the structure showed the same enhancement pattern as the adjacent ileal loops, which suggested that the lesion was a part of the ileum (Pic...

A repeated bijection in an isotopism of quasigroups is called a companion of the third component. The last is called a pseudoisomorphism with the companion. Isotopy coincides with pseudoisomorphy∗ in the class of inverse property loops and with isomorphy in the class of commutative inverse property loops. This result is a generalization of the corresponding theorem for commutative Moufang loops...

The structure of the commutative Moufang loops (CML) with minimum condition for subloops is examined. In particular it is proved that such a CML Q is a finite extension of a direct product of a finite number of the quasicyclic groups, lying in the centre of the CML Q. It is shown that the minimum conditions for subloops and for normal subloops are equivalent in a CML. Moreover, such CML also ch...

Computation models such as circuits describe sequences of computation steps that are carried out one after the other. In other words, algorithm design is traditionally subject to the restriction imposed by a fixed causal order. We address a novel computing paradigm, replacing this assumption by mere logical consistency: We study non-causal circuits, where a fixed time structure within a gate is...

We study the structure and dynamics of active region magnetic loops at transition region temperatures by analyzing high resolution observations of the active region NOAA 7962 at the limb on 1996 May 6. During the decay phase of a B-class are which occurred at the active region, the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectrograph on board the Solar and Heliospheric Obser...

We present an unusual case of acute abdomen caused by torsion of an accessory spleen with situs inversus in a child. A three-year-old girl was admitted to our hospital with an 11-day history of right flank pain with fever. Her medical history revealed an operation of coarctation of the aorta with situs inversus at one month of age. Physical examination revealed a right flank mass and tenderness...

Thirty-four elderly patients with right bundle-branch block and left axis deviation were studied vectorcardiographically utilizing the McFee-Parungao system. Atherosclerosis, arterial hypertension, angina pectoris, cardiac enlargement, and heart failure were common clinical features in this series. Moreover, intermittent advanced degree of atrioventricular block was present in 10 out of the 34 ...

the textit{commutativity degree}, $pr(g)$, of a finite group $g$ (i.e. the probability that two (randomly chosen) elements of $g$ commute with respect to its operation)) has been studied well by many authors. it is well-known that the best upper bound for $pr(g)$ is $frac{5}{8}$ for a finite non--abelian group $g$. in this paper, we will define the same concept for a finite non--abelian textit{...
