An electronic display cycling through the six die faces while a switch is pressed. A modulo-six counter and combinational logic can drive seven lights arranged as die pips. The apparent unpredictability comes from uncertainty in release timing relative to a rapid clock signal; deterministic cycling alone does not establish equal outcome probabilities.

Pair candidates from a totally ordered set and retain the greater one from each comparison until one winner remains. Every other candidate loses once, so $n-1$ key comparisons suffice to find the maximum of $n$ distinct values. A balanced tournament on $2^m$ inputs gives the winner $m$ direct losers. Retaining each loser's own defeat record preserves information for finding later order statistics. The comparison records form a rooted tree and are distinct from a graph-theoretic tournament, which includes a directed comparison between every pair.

A family of 11S seed storage globulins. The older term vegetable casein does not imply identity with milk casein.

Glandular secretion is release of products by a gland. Exocrine routes deliver material through ducts, while an endocrine gland releases signals toward the circulation. Flow rate and composition can change independently, as illustrated by salivary secretion.

A haematocele is a collection of blood within a body cavity or sac; in scrotal anatomy it commonly refers to blood in the tunica vaginalis space. It differs from a solid testicular lesion and from a non-bloody fluid collection.

A varicocele is enlargement of veins in the pampiniform plexus associated with the spermatic cord. It is therefore a vascular change outside the testicular tissue. Venous anatomy and drainage help explain its distribution, while the finding alone does not specify every aspect of reproductive function.

The glenoid cavity is the shallow articular surface of the scapula receiving the humeral head. The glenoid labrum deepens its rim. This shallow geometry permits extensive movement but makes stability depend strongly on soft tissues and active muscular control.

The coracoid process is an anterior projection from the scapula. It provides attachment for muscles and ligaments, including pectoralis minor. Its location supplies a recognizable landmark near several structures of the shoulder region.

The scapular spine is the prominent ridge on the posterior scapula. It separates the supraspinous and infraspinous regions and extends laterally toward the acromion. Its shape provides attachment and leverage for shoulder muscles.

Represent a row by sorted disjoint half-open intervals, each carrying a colour. Merge touching intervals precisely when their colours agree. The resulting ordered maximal runs form a canonical representation of occupancy and colour: equality of those runs is equivalent to pointwise equality, while ignoring arbitrary subdivisions inside one colour run. For two rows containing $m$ and $n$ intervals, constructing and comparing runs takes $O(m+n)$ time complexity, independently of coordinate magnitude or interval lengths.

Store both the last recipient index $L$ and a current-grant valid bit $V$. With $k$ possible recipients, an idle period clears $V$ while preserving $L$. The Moore machine grants requester $j$ precisely when $V\wedge [L=j]$ holds. For $k>1$, its $k$ idle states are distinguishable by a subsequent pair of competing requests with different positions in the cyclic order; active states have distinct outputs. Thus all $2k$ states are distinguishable and $\lceil {\log }_2(2k)\rceil$ state bits suffice and are necessary for this output convention. A continuously asserted request receives a grant within $k$ decisions, because before that grant the cyclic scan cannot pass it to choose a later asserted request.

A systemic inflammatory disorder that commonly affects synovial anatomical joints. Persistent immune-mediated inflammation can damage cartilage and bone; the disease differs from defining every chronic joint pain as ordinary degeneration.^[ref]

A disorder involving changes in the whole anatomical joint, including cartilage, bone and surrounding tissues. It is more than a passive wearing away of cartilage and differs mechanistically from autoimmune rheumatoid arthritis.^[ref]

An inflammatory arthritis associated with deposition of urate crystals in anatomical joints. Historical descriptions of podagra require interpretation rather than automatic assignment of every ancient patient to this modern category. ^[ref]

Historical umbrella for painful musculoskeletal disorders, including conditions now separated as acute rheumatic fever, rheumatoid arthritis and osteoarthritis. It is not a single modern pathological diagnosis.

Retinopathy is disease or damage of the retina. Vascular, metabolic, inherited and other processes can affect different retinal layers or regions. The term identifies the affected tissue without specifying one cause or one pattern of visual loss.

The ora serrata is the anterior boundary of the photosensitive retinal region, where it meets the nonvisual epithelial continuation toward the ciliary body. The boundary distinguishes changes in tissue organization rather than an abrupt end of every retinal epithelial layer.

A respiratory muscle changes the geometry or pressure of the breathing apparatus. The respiratory diaphragm enlarges the thorax during inspiration; intercostal muscles and, under suitable conditions, accessory muscles contribute. Quiet expiration can be largely passive, whereas forceful expiration recruits additional muscular activity.

The pleura is a serous membrane with a visceral layer covering a lung and a parietal layer lining the adjacent thoracic wall. The intervening pleural cavity normally contains a thin fluid film. Sliding at this interface permits breathing movements while preserving mechanical coupling between the lung and thorax.^[ref]
