Noise-assisted digital quantum simulation of open systems

Guimarães, José D.; Lim, James; Vasilevskiy, Mikhail; Huelga, Susana F.; Plenio, Martin B.

Quantum systems are inherently open and susceptible to environmental noise, which can have both detrimental and beneficial effects on their dynamics. This phenomenon has been observed in bio-molecular systems, where noise enables novel functionalities, making the simulation of their dynamics a crucial target for digital and analog quantum simulation. Nevertheless, the computational capabilities of current quant...


Parâmetros reprodutivos e produtivos em vacas leiteiras de manejo free stall

Pereira, Jhonata V.; Costa, Eduardo P. da; Marcondes, Marcos I.; Maitan, Paula P.; Nogueira, Amanda R.; Guimarães, José D.; Villadiego, Faider A. C.

Avaliou-se parâmetros reprodutivos e produtivos em vacas da raça Holandês-PB no pós-parto imediato, manejadas em free stall . Utilizou-se 51 vacas entre primíparas e pluríparas. Os valores obtidos foram: escore de condição corporal ao parto 3,47±0,4; intervalos do parto à primeira ovulação 5,89±3,4 semanas; ao primeiro serviço 112,5±57,0 dias; a taxa de gestação ao primeiro serviço foi 43,6% e no período experi...

Detection of bovine herpesvirus 1 in cumulus-oocyte complexes of cows

Queiroz-Castro, Vanessa L. D.; Costa, Eduardo P. da; Alves, Saullo Vinicius P.; Silva Júnior, Abelardo; Machado-Neves, Mariana; Guimarães, José D.

Bovine herpesvirus 1 (BoHV-1) is the causative agent of infectious bovine rhinotracheitis (IBR) and is also associated with reproductive failure. This study investigated the presence of BoHV-1 in cumulus-oocyte complexes (COCs) of naturally-infected cows without clinical signs of IBR. The presence of BoHV-1 in COCs was evaluated by immunofluorescence using confocal laser scanning microscopy. Blood samples and o...

In vitro evaluation of cryopreserved bovine sperm and its relation to field fer...

Okano, Denise S.; Penitente‐Filho, Jurandy M.; León, Victor E. Gomez; Maitan, Paula P.; Silveira, Camila O.; Waddington, Bruna; Díaz‐Miranda, Edgar A.

This study aimed to assess characteristics of bovine cryopreserved sperm and evaluate its relation to field fertility in fixed‐time artificial insemination (FTAI). Semen samples of 16 bulls were used to inseminate 811 Nellore cows, and four of these bulls were also used to inseminate 101 Nellore heifers. Samples of the same ejaculate used for FTAI from each bull were analysed in the laboratory after thawing. Sp...

Morphological and molecular differences in corpus luteum of pregnant sows from ...

Costa, Karine A.; Silva, Walmir da; Veroneze, Renata; Montes, José C.; Verardo, Lucas L.; Botelho, Margareth E.; Duarte, Marcio S.; Neves, Mariana M.

Comprehending mechanisms controlling corpus luteum (CL) angiogenesis and apoptosis in pregnant sows is essential to understand the physiological role of these processes in CL function, progesterone production and consequently in conceptus development and prenatal mortality. CL from 54 sows from two genetic groups, a commercial line (COM) and the local Piau breed (LPB), were obtained for gene expression (n = 3 C...

Efeito de soluções eletrolíticas enterais com diferentes osmolaridades sobre o ...

Ribeiro Filho, José D.; Farias, Sheila K.; Donner, Athina C.; Oliveira, Dyego P.; Guimarães, José D.; Souza, Maria V.; Gomes, Cláudio L.N.

Foram comparados os efeitos de soluções eletrolíticas com diferentes osmolaridades administradas via enteral por sonda nasoesofágica de pequeno calibre, em fluxo contínuo, sobre o perfil bioquímico em equinos. Foram utilizadas seis fêmeas adultas em dois quadrados latinos 6x3 simultâneos em modelo misto. Os animais foram distribuídos em três grupos e cada grupo submetido aos seguintes tratamentos: HipoMalt - 5g...
