Deep Digital Flexor Tendon Injury at the Level of the Proximal Phalanx in Frontlimbs With Tendon Sheath Distension Characterized by Standing Low-Field Magnetic Resonance Imaging in Horses: 13 Cases (2015–2021)

open access: yesFrontiers in Veterinary Science, 2021
Objective: To describe the MRI findings for 13 horses with deep digital flexor tendon (DDFT) injury at the proximal phalanx where the tendon goes from ovoid to bilobed in frontlimbs with tendon sheath distension. In addition, the prognosis of this lesion

Charting the Real Four-Qubit Pauli Group via Ovoids of a Hyperbolic Quadric of PG(7,2) [PDF]

open access: yes, 2012
The geometry of the real four-qubit Pauli group, being embodied in the structure of the symplectic polar space W(7,2), is analyzed in terms of ovoids of a hyperbolic quadric of PG(7,2), the seven-dimensional projective space of order two.

Ovoidal linear spaces

open access: yesDiscrete Mathematics, 2003
A finite linear space \(L = (P, {\mathcal L})\) of dimension \(d\) not less than 3 is called \(n\)-ovoidal, if there is an \(n\)-cap (a subset of \(n\) points intersecting each line in at most two points) satisfying the following conditions: (i) the number of external lines is smaller than or equal to the number of secant lines; (ii) for any two ...

Correlation Between Filling Defect Patterns on Urography and Pathologic Staging of Ureteral Transitional Cell Carcinomas

open access: yesKaohsiung Journal of Medical Sciences, 2003
Although a filling defect within the ureter is the most common finding with ureteral transitional cell carcinomas (TCCs), little is known about the correlation between filling defect patterns and pathologic findings.

De Novo Design of a Highly Stable Ovoid TIM Barrel: Unlocking Pocket Shape towards Functional Design

open access: yesBioDesign Research, 2022
The ability to finely control the structure of protein folds is an important prerequisite to functional protein design. The TIM barrel fold is an important target for these efforts as it is highly enriched for diverse functions in nature.

The pseudo-hyperplanes and homogeneous pseudo-embeddings of the generalized quadrangles of order (3, t) [PDF]

open access: yes, 2012
In the paper "as reported by De Bruyn (Adv Geom, to appear)", we introduced the notions of pseudo-hyperplane and pseudo-embedding of a point-line geometry and proved that every generalized quadrangle of order (s, t), 2 a parts per thousand currency sign ...

Mathematical interpretation of artificial ovoids and avian egg shapes (part I)

open access: yesRegulatory Mechanisms in Biosystems, 2019
We performed comparative analysis of curvature characteristics of bird eggs and used ovoid profiles from various authors, our own geometric profiles, and archive bird egg profiles from our database. We suggested that the possible ovoids arise by changing

Adult onset of xanthelasmoid mastocytosis: Report of a rare entity

open access: yesIndian Journal of Dermatology, 2016
Xanthelasmoid or pseudoxanthomatous mastocytosis is an extremely rare variant of diffuse cutaneous mastocytosis. Herein, we describe an adult male with cutaneous mastocytosis showing multiple widespread yellowish ovoid papules like eruptive xanthoma.
