“…The systematic review identified 17 studies conducted between 1979 and 2019 that reported the prevalence of brucellosis in different animals including sheep, goats, cattle, and/or buffalo. Animals used in the identified studies included those from slaughterhouse (e.g., [2,24,27]), flocks (e.g., [3,7,28]), random animals (e.g., [27,32]), aborted ewes (e.g., [8,10,34], ewes regardless of the abortion or vaccination status (e.g., [29,30], or rams only [35]. The identified studies have focused on the standardized techniques used for collecting and handling blood samples, as well as the diagnostic tests used for classifying infected and uninfected animals.…”

Brucellosis is an endemic disease in food-producing animals in Mosul, Iraq. The objectives of the study reported here were: (i) to identify and assess the evidence and knowledge gaps in published studies that have examined brucellosis in different food-producing animals in Mosul, Iraq; using systematic review approach, and (ii) to quantify the seroprevalence of brucellosis in the city using meta-analysis approach. Google Scholar was used as a search engine to track pertinent peer-reviewed research reports. The search was conducted on November 24, 2019. Keywords used were: brucella, animal, Mosul, Iraq. Peer-reviewed published studies, MSc theses, and PhD dissertations written in Arabic or English were included. Duplicate records were removed, and the screening process was conducted at three levels: titles, abstracts, and full-text articles. Identified studies that have reported the seroprevalence of brucellosis were included in a meta-analysis to calculate an overall prevalence. A total of 214 records were initially identified. Seventeen research reports were added from personal contact and qualified articles' references list. Thirty six articles were qualified for review after removing 35 duplicate records, 155 titles, 11 abstracts, and 5 full text articles. Seventeen studies reported the prevalence of brucellosis, 11 studies assessed different serological tests for diagnosis of brucellosis, 9 studies isolated Brucella spp. from animal specimens and/or animal products, and 4 studies assessed vaccination procedures against brucellosis. The overall seroprevalence of brucellosis in food-producing animals in Mosul over a period of 40 years was 14.14%, including 14.46% for sheep, 12.99% for goats, 11.69% for cattle, and 22.64% for buffalo. The study concluded that the disease is evident in the city with increasing trends over the years, buffalo shows high seroprevalence, the degree of agreement of Rose-Bengal test as a screening test is fair compared to more accurate serological tests such as ELISA; and the disease constitutes a public health concern in the city. Additional studies are important to identify the overlooked predisposing factors, estimate the abortion rate attributable to brucellosis in food-producing animals, and evaluate efficacy of vaccination programs in reducing the prevalence of brucellosis and/or abortion rate.

“…In the camel, the prevalence rate was 16.29% in Wasit province (6), and 8.6% in Erbil province (7). In Mosul province, the infection rate of ovine brucellosis was 15.9 % using the ELISA test on different samples of sheep herds (8) and 25.6% using Rose Bengal test and 2-mercaptoethanol test in goats (9). In cattle, abortion is presented as the main clinical manifestation of the disease with B. abortus strain (10).…”

Brucellosis is an endemic disease in many countries of the middle east including Iraq, despite the high attempts to control the disease in animals using vaccination programs. The study was conducted from January to March 2012, to determine the prevalence of bovine brucellosis in the Al-Najaf province in Iraq, which represent risk factors associated with brucellosis in cattle. Blood samples were collected from 172 cows and 15 bulls of 20 dualpurpose cattle herds. Serological examinations are the most useful and widely used tool for the diagnosis of brucellosis in man and animals. All animal serum samples were tested by the Rose Bengal plate test (RBT), and the positive cases were confirmed by competitive enzyme-linked immunosorbent assay (c-ELISA). The overall prevalence of brucellosis was 5.81% divided between 5.81% in females and 0% in males, and 40% as herd numbers level. Females showed a higher seropositive reaction to the disease than males. In conclusion, this study demonstrated the presence of the disease and detected the seropositive reactions in animal samples in different farms of the province, with a difference in infection rate regarding the risk factor. Sanitary measures must be taken to avoid the occurrence and spread of the disease in humans and animals.

“…Applications of surrogate models range from aerospace science [29][30][31], geostatistics [32,33], engineering design [34,35], risk analysis [36,37], optimization [38] to machine learning techniques [39]. All applications are computationally expensive and for many cases the software used is proprietary and hence must be treated as a black box for the construction of the surrogate models.…”

Bayesian approach to determine critical dimensions from scatterometric measurements

2018

Supplement one of the 'Guide to the Expression of Uncertainties in Measurements (GUM)' recommends to estimate measurement uncertainties by Monte Carlo calculations. For computationally expensive models, Monte Carlo sampling can be often only realized for a small number of samples. This may cause inaccurate or even useless results for problems with a slow convergence rate. In this paper we apply a recently developed method that enables the Bayesian approach to determine the geometry of photo masks from measurements in extreme ultraviolet (EUV) scatterometry. The key idea of this approach is the construction of an efficient surrogate model which reduces the computational costs of sampling steps by several orders of magnitude. This allows us to use Markov Chain Monte Carlo sampling to determine the posterior distribution of desired critical dimensions of the photo mask geometry. The Bayesian approach leads to substantially larger uncertainties of the critical dimension than the previously employed maximum likelihood approach. The results for critical dimensions and line edge roughness are consistent with independent atomic force measurements of a test photo mask arrays from which scatterometric data were used.
