Abstract

The double copy relates scattering amplitudes in gauge and gravity theories. In this paper, we expand the scope of the double copy to construct spacetime metrics through a systematic perturbative expansion. The perturbative procedure is based on direct calculation in Yang-Mills theory, followed by squaring the numerator of certain perturbative diagrams as specified by the double-copy algorithm. The simplest spherically symmetric, stationary spacetime from the point of view of this procedure is a particular member of the Janis-Newman-Winicour family of naked singularities. Our work paves the way for applications of the double copy to physically interesting problems such as perturbative black-hole scattering., Comment: v2: 20 pages + refs, minor improvements

Abstract

Experiments were conducted to determine the efficacy in stimulating and maintaining an immune response in the presence of maternal antibodies, compare the extent of the anamnestic responses to revaccination, and compare the maternal antibody response of 2- or 5-mL clostridial vaccination. In Exp. 1, 118 nursing calves were randomly assigned to receive a 2-mL (Alpha-7[R], A7) or a 5-mL clostridial vaccine (Ultrabac[R] 7; UB7) at 50.4 [+ or -] 15.30 [Mathematical Expression Omitted] d of age (d 0 = date of calving). Calves were revaccinated with the same treatment on d 170. Blood samples were collected from 10 calves of each treatment group on d 50, 170, and 191 to determine antitoxin units for Clostridium perfringens type C (PC) and D (PD) and agglutination titers for Cl. chauvoei (CC). The A7-treated calves tended (P < .10) to have higher PC units on d 170, an increased rate of change in PD units from d 170 to d 191 (P < .06), and a tendency (P < .10) for enhanced CC titers on d 191 compared with UB7-treated calves. In Exp. 2, 109 pregnant cows and 83 pregnant heifers were randomly assigned within a 2 x 2 x 2 factorial design. The main effects were dam age (cow or heifer), dam treatment (A7 or UB7), and calf treatment (A7 or UB7). Dams were vaccinated with A7 or UB7 d 124 prepartum (d -124) and d 53 after birth. At d 53.4 [+ or -] 12.88, calves were vaccinated with A7 or UB7 (d 53). Calves were revaccinated with the same treatment on d 173. Blood samples were collected from 10 dams per treatment group on d -124, 53, and 173 and from their calves on d 53, 173, and 194. Cows had higher antitoxin levels for PC (P < .01) and PD (P < .05) than heifers. The A7-treated dams had higher (P < .01) PD units on d 53 and d 173 and CC on d 173 than did UB7-treated dams. Calves from A7-treated cows had higher (P < .03) PD units on d 53 than calves from UB7-treated cows. The A7-treated calves had higher titers for CC (P < .01) on d 173 than did UB7-treated calves, and this enhanced level seemed to continue to d 194 (P < .08). In conclusion, titers for clostridial diseases in 50- to 53-d-old calves can be enhanced if dams are vaccinated approximately 4 mo before calving, and 120 d between clostridial vaccinations seems to be too long for adequate protection.

39. Is the caudal auricular axial pattern flap robust? A multi‐centre cohort study of 16 dogs and 12 cats (2005 to 2016).

Abstract

Objective: To determine the frequency and type of healing complications arising after the use of the caudal auricular axial pattern flap to close defects on the head in dogs and cats. Material and Methods: Multi‐centre retrospective cohort study. Centres were recruited by the Association for Veterinary Soft Tissue Surgery Research Cooperative. Medical records of 11 centres were reviewed, and data from all dogs and cats treated with a caudal auricular axial pattern flap were retrieved. The following data were recorded: signalment, reason for reconstruction, flap dimensions, anatomic landmarks used, histological diagnosis, flap healing and whether revision surgery was required. Results: Twenty‐eight cases were included: 16 dogs and 12 cats. Flap length: width ratio was approximately 3:1 and flap length extended to the scapular spine in most cases. Optimal wound healing occurred in five of 16 (31%) dogs and six of 12 (50%) cats. Wound dehiscence without flap necrosis occurred in one of 16 (6%) dogs and one of 12 (8%) cats. Wound dehiscence with flap necrosis occurred in 10 of 16 (63%) dogs and five of 12 (42%) cats. Revision surgery was performed in eight of 16 (50%) dogs and three of 12 (25%) cats. Clinical Significance: The caudal auricular axial pattern flap can provide full thickness skin coverage for large defects on the head in dogs and cats. Partial flap necrosis is a common complication, and revision surgery may be required in order to achieve final wound closure. [ABSTRACT FROM AUTHOR]
