Damage spreading in small world Ising models.

Physical review. E, Statistical, nonlinear, and soft matter physics

Svenson P, Johnston DA.
PMID: 11909163
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Mar;65(3):036105. doi: 10.1103/PhysRevE.65.036105. Epub 2002 Feb 08.

We study damage spreading in the ferromagnetic Ising model on small world networks using Monte Carlo simulation with Glauber dynamics. The damage spreading temperature T(d) is determined as a function of rewiring probability p for small world networks obtained...

PCR detection of Hordeum bulbosum introgressions in an H. vulgare background using a retrotransposon-like sequence.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Johnston PA, Pickering RA.
PMID: 12582679
Theor Appl Genet. 2002 Mar;104(4):720-726. doi: 10.1007/s00122-001-0791-2.

Retrotransposon-like sequences are ideal tools for initial screening assays to distinguish between closely related species because of their ubiquitous presence, high copy number, chromosome coverage and rapid sequence evolution. A retrotransposon-like sequence, pSc119.1, cloned from Secale cereale (rye) has...

Synthesis of arene-soluble mixed-metal Zr/Ce, Zr/Y, and related [[Zr2(OiPr)9]LnX2]n complexes using the dizirconium nonaisopropoxide ligand.

Inorganic chemistry

Evans WJ, Johnston MA, Greci MA, Ansari MA, Brady JC, Ziller JW.
PMID: 12526523
Inorg Chem. 2000 May 15;39(10):2125-9. doi: 10.1021/ic991272+.

The utility of polydentate monoanionic [Zr2(OiPr)9]- in generating arene-soluble, unsolvated, mixed-metal Zr/Ce and Zr/Y complexes is described. The synthesis of other mixed-metal zirconium lanthanide complexes was also studied to explore the relationship of metal size to structure. Lanthanide trihalides...

Switchable electronic coupling in model oligoporphyrin molecular wires examined through the measurement and assignment of electronic absorption spectra.

Journal of the American Chemical Society

Sendt K, Johnston LA, Hough WA, Crossley MJ, Hush NS, Reimers JR.
PMID: 12149038
J Am Chem Soc. 2002 Aug 07;124(31):9299-309. doi: 10.1021/ja020081u.

The use of a quinone functionality in the linkage unit of laterally bridged oligoporphyrins as a switch for controlling electronic coupling between the termini is examined. The quinone-bridged bisporphyrin P(2)TA-O(2) was synthesized by condensation of 2 equiv of the...

Environment-dependent performance and fitness of Iris brevicaulis, I. fulva (Iridaceae), and hybrids.

American journal of botany

Johnston JA, Grise DJ, Donovan LA, Arnold ML.
PMID: 11353718
Am J Bot. 2001 May;88(5):933-8.

We tested the relative fitness of two Louisiana Iris species (Iris brevicaulis and I. fulva) and their first-generation backcross hybrids in three experimental watering treatments: dry, field capacity, and flooded. Leaf area expansion rate, gas exchange (A(max), g(s), c(i)),...

Adherence to Drug-Dispensation and Drug-Administration Laws and Guidelines in Collegiate Athletic Training Rooms.

Journal of athletic training

Kahanov L, Furst D, Johnson S, Roberts J.
PMID: 14608436
J Athl Train. 2003 Sep;38(3):252-258.

OBJECTIVE: To assess adherence in collegiate athletic training rooms to federal drug laws and to describe current practices. DESIGN AND SETTING: We created a survey of drug-law adherence using federal drug laws and administration guidelines and mailed it to...

Knowledge and attitudes of Hispanic women and their health care providers about breast cancer risk factors and screening.

Community genetics

Strecker MN, Williams AJ, Bondy M, Johnston DA, Northrup H.
PMID: 14960876
Community Genet. 2002;5(4):222-31. doi: 10.1159/000066685.

OBJECTIVES: The purpose of our study was to develop and evaluate an educational program for health care providers and patients on the topics of general breast cancer risk factors, breast cancer genetics, and breast cancer screening recommendations. The program...

Neuromuscular determinants of force coordination during multidigit grasping.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Johnston JA, Winges SA, Santello M.
PMID: 17271343
Conf Proc IEEE Eng Med Biol Soc. 2004;2004:4645-8. doi: 10.1109/IEMBS.2004.1404287.

The biomechanical structure of the hand and its underlying neurophysiology contribute to the coordination of the kinematics and kinetics necessary for multidigit grasping. We recently examined the neural organization of inputs to different extrinsic finger flexors during multi-digit object...

Diphallia in a mixed-breed dog with multiple anomalies.

Theriogenology

Johnston SD, Bailie NC, Hayden DW, Johnston GR, Osborne CA.
PMID: 16726645
Theriogenology. 1989 Jun;31(6):1253-60. doi: 10.1016/0093-691x(89)90096-4.

Complete diphallia was detected in a six-month-old Poodle cross dog. Duplication of the urinary bladder, right renal hypoplasia, bifurcation of the descending colon and bilateral cryptorchidism were also present. The left urethra was patent, and emptied the left urinary...

Influence of culture medium and protein supplementation on in vitro oocyte maturation and fertilization in the domestic cat.

Domestic cat oocytes were cultured either in Waymouth MB 753/1 Medium (WAY) or in Eagle's Minimum Essential Medium (MEM) containing FSH, LH and estradiol-17beta and supplememted with one of the following: 5% fetal calf serum (FCS); 4 mg/ml bovine...

Concurrent retrograde ejaculation and hypothyroidism in a dog: case report.
