title: Using OMOPSO & MMOPSO algorithms on water distribution systems design.

description: The particle swarm optimization, PSO, was firstly developed by Kennedy & Eberhart (1995) to solve simple single-objective continuous optimization problems. This algorithm depends mainly on imitating the concept of swarm intelligence which is extensively found in birds flocks or fish schools. The algorithm initiates a prespecified number of flying particles that are led by a leader which moves towards the area of the global optimum solution with the most reasonable direction and flying speed. The algorithm keeps iterating while improving the positions and flying speeds for all the particles by following the particles’ leader. Eventually, the algorithm may reach the global optimum or may fall in local optima (if any). Coello Coello & Lechuga (2002) extended the usage of the PSO algorithm to adapt with multi-objective optimization problems by providing an external archive to store the set of non-dominated solutions that may be found during the search. The original multi-objective particle swarm optimization, OMOPSO, algorithm usually suffers from some difficulties when it is applied in the problem of designing water distribution systems (WDSs) since this problem is a combinatorial discrete NP-hard optimization problem (Montalvo et al., 2010; Surco et al., 2017). The algorithm frequently falls in local minima during the search and fails to capture the whole set of non-dominated feasible solutions after the end of search especially in medium to large search space problems. Therefore, a trial is made to improve the performance of the OMOPSO in designing WDSs by developing a modified multi-objective particle swarm optimization, MMOPSO. The modifications include using some strategies to improve the overall convergence and diversity of the final non-dominated feasible set of solutions such as; the self-adaptive PSO parameters strategy, the selection strategy of the external archive members, the regeneration-on-collision strategy, and the adaptive population size strategy. In the subsequent sections, the pseudo-codes of the OMOPSO and MMOPSO are presented, the explanations of using both algorithms are provided, and an example of using both algorithms is illustrated.

title: Phenomics approaches: genetic diversity and variance components in a S2 guava family by seed traits

description: ABSTRACT Guava is of great economic importance in Brazil. The development of new cultivars by obtaining inbreeding lines has been a promising option. The objective of this work was to evaluate the S2 families of Psidium guajava using seed attributes. Different characters of physiological quality of guava seeds were studied, in addition to performing digital phenotyping of characteristics of geometry, texture and colors of the seeds. The variables were analyzed simultaneously using the Ward-Modified Location Model (MLM) method and carried out individual analyses of variance for estimating genetic parameters of the population. The formation of more than one group of divergent genotypes was observed, the geometry characteristics were more impacting for the discrimination of the genotypes, a high phenotypic correlation was observed with the germination variables and dry matter weight. High heritabilities were verified for the variables related to seed quality, indicating success in selecting vigorous genotypes. The Ward-MLM method is a useful tool to detect genetic diversity among genotypes of inbred guava. Thus, the most divergent genotypes with high germination potential can be recommended for future crosses or self-fertilized to obtain new lines in the guava breeding program.

title: Medidas Recentes de Desoneração Tributária no Brasil: Uma Análise de Equilíbrio Geral Computável

description: The objective of this study is to assess the economic impacts of release of payroll as proposed by Federal Government policy. For this purpose, it has been used a computable general equilibrium model designed for comparative static simulations. The results show positive effects for the long-term growth of the economy, increasing employment, GDP and household consumption. However, there is a negative effect on exports. We conclude that the choice of the sectors covered by the policy may represent a crucial point for its effectiveness.

title: Previdência e Taxa de Juros no Brasil

description: This paper studies how Brazil's high real interest rate is related to the country's pay-as-you-go (PAYG) pension system, which features exceptionally large expenses. We use a standard version of the overlapping generations model, with a mixed pension system (part PAYG part fully funded). We calibrate the model to the Brazilian economy between 2000 and 2014. We consider a steady state which reproduces the average real interest rate in this period, with a PAYG system. We then simulate a pension reform to replicate Chile's pension expenses. Like Brazil, Chile is a Latin American middle income country, but its pension system is mostly of the fully-funded type. In our preferred specification, the model predicts a 1 percentage point decrease in the long-run annual real interest rate. This corresponds to 18% of the average interest differencial between Brazil and Chile during the 2000-2014 period.

title: Clinical and radiologic outcomes of pleomorphic adenoma and adenoid cystic carcinoma of the lacrimal gland

description: ABSTRACT Purpose: To compare the radiologic and clinical features of primary lacrimal gland pleomorphic adenoma and adenoid cystic carcinoma. Methods: This study retrospectively reviewed imaging findings and medical records of lacrimal gland pleomorphic adenoma and adenoid cystic carcinoma. Results: Eleven patients with pleomorphic adenoma and 16 patients with adenoid cystic carcinoma were evaluated. There were no statistically significant differences between groups regarding age or sex. Proptosis was the most common presenting symptom in both groups. Adenoid cystic carcinomas were more likely to present with a palpable mass, diplopia, pain, and sensory loss than pleomorphic adenomas, although the differences were not statistically significant between groups. Furthermore, there were no significant differences in terms of homogeneity and globe indentation between lacrimal gland pleomorphic adenoma and adenoid cystic carcinoma on computed tomography (CT)(all p&gt;0.05). The rates of bone invasion, tumor calcification, and wedge sign were significantly higher in adenoid cystic carcinomas, and bone remodeling was statistically significantly higher in pleomorphic adenomas, on CT(all p&lt;0.05). Pleomorphic adenomas were significantly more likely to show well-defined margins, lobulated contours, heterogeneous contrast enhancement, and hyperintensity on T2-weighted magnetic resonance images (all p&lt;0.05). Conclusion: When differentiating between lacrimal gland pleomorphic adenoma and adenoid cystic carcinoma, evaluation of radiologic features along with clinical features is of great importance. Lobulated contours may be a significant distinguishing radiologic feature suggesting pleomorphic adenoma.

title: Phototherapeutic keratectomy: current approaches and changing trends in a tertiary eye clinic

description: ABSTRACT Purpose: To examine the efficacy of phototherapeutic keratectomy as a treatment for variable pathologies with anterior corneal opacities and evaluate the distribution of phototherapeutic keratectomy indications over the past 10 years. Methods: The records of 334 eyes from 276 patients who underwent phototherapeutic keratectomy between March 2010 and 2020 were retrospectively reviewed. Etiologies of the patients who underwent phototherapeutic keratectomy were noted, and their changes were examined. Refractive and visual acuity results before and after the operation were recorded and analyzed according to etiology. Results: The mean age of the patients was 40.7 ± 16.2 years (range: 19-84). The mean follow-up was 25.5 ± 19.1 months (range: 3-96). Phototherapeutic keratectomy was most frequently applied for corneal stromal dystrophies (44%, 151 eyes from 111 patients), and granular dystrophy was the most common phototherapeutic keratectomy indication among corneal dystrophies. Unlike other indications, there has been an increase in the application of phototherapeutic keratectomy for persistent subepithelial opacities due to adenoviral conjunctivitis in the past 10 years. There was a significant increase in visual acuity in all groups except for the recurrent epithelial defect group (p&lt;0.05). The greatest improvement in visual acuity was detected for stromal dystrophies in the granular dystrophy subgroup. Conclusion: Despite changing indication trends, phototherapeutic keratectomy remains an effective and reliable treatment for anterior corneal lesions.

title: A note on Brazilian IPOs performance in the long run

description: Abstract This note examines the long-run performance of Brazilian IPOs based on a sample of 143 firms that went public between 2004 and 2013. There is no evidence that IPOs underperform the market in the 60 months after going public. An investor would have to put 12.6% more money in an investment that mimics the index than in the IPOs to achieve the same terminal wealth level five years later. IPOs with the highest initial returns have the worst aftermarket performance and there is mixed evidence that larger IPOs underperform the smaller IPOs in the five years subsequent to the offerings.

title: Os recursos hídricos no agronegócio brasileiro: Uma análise insumo-produto do uso, consumo, eficiência e intensidade

description: Abstract In this paper, in agribusiness, the use and consumption of water, as well as the level of efficiency and intensity of water in relation to income and employment are analyzed. To do this, the Environmental Water Accounts with the country’s input-output matrix of 2015 are disaggregated and reconciled. Agribusiness activities account for 18,85% of water use and 90% of the country’s water consumption. The best indices of efficiency and intensity of income and employment generation highlighted, in relation to the use of water, the agribusiness and, in water consumption, agri-services. The rates of consumption and the rates of return of water to the environment show that, for each hm3/year of water used, in agriculture and cattle raising, 70,45% is incorporated in its production and 29,55% returns to the environment; and, in the agroindustry, the consumption rate is 54,58% and return 45,42%. Therefore, if we consider that agribusiness is a major exporter of food for the international market, we can also affirm that, through its exports, it supplies significant volumes of water resources to the world economy.

title: Elections, heterogeneity of central bankers and inflationary pressure: The case for staggered terms for the president and the central banker

description: Abstract This paper analyzes a signaling model of monetary policy when inflation targets are not set by the monetary authority. The most important implication of the model’s solution is that a higher ex-ante dispersion in central bankers’ preferences, referred to as heterogeneity in policy orientation, increases the signaling cost of commitment to inflation targets. The model allows for a comparison of two distinct institutional arrangements regarding the tenure in office of the central banker and the head of government. We find that staggered terms yield superior equilibria when opportunistic political business cycles can arise from presidential elections. This is a consequence of a reduction of information asymmetry about monetary policy, and gives theoretic support to the observed practice of staggered terms among independent central banks.
