STOCHASTIC MODELING OF LIMIT ORDER BOOKS: CONVERGENCE OF THE PRICE PROCESS, SIMULATION AND APPLICATIONS

In the past two decades, electronic limit order books (LOBs) have become the most important mechanism through which securities are traded. A LOB contains the current supply and demand of a security at different prices and it can be modeled as a random, state-dependent, and high-dimensional system since typically a great number of orders are placed at many different prices at a millisecond time scale. These features lead to an inherent mathematical complexity which is extremely hard to describe in a tractable manner. Thus, depending on the purpose, different models have been proposed to capture specific properties of the underlying trading mechanism, making LOB modeling a trending topic in the quantitative and investment finance literature for the past few years. Some of the most important objectives for which a LOB model is designed are to provide algorithmic trading strategies, bottom-up estimates for a variety of parameters, better understanding of asset price formation

Helminths from Dormitator maculatus (Pisces: Eleotridae) in Alvarado Lagoon, Veracruz, Mexico, and Supplemental Data for Clinostomum complanatum Rudolphi, 1814 from Egretta caerulea (Aves: Ardeidae)

Fishes are important hosts of helminths with aquatic life stages, yet little information is available on host-parasite relationships in tropical low salinity ecosystems. In this paper we report helminth parasites of the fat sleeper, Dormitator maculatus, in the Alvarado lagoon system, Veracruz. Mexico. Four parasite species were recorded from D. maculatus, including trematode metacercariae of Clinostomum complanatum, as well as nematode larvae of Spyroxis sp. and Camallanus sp. and adults of Neochinorhynchus golvani. In addition, we obtained adult C. complanatum from the esophagus of the little blue heron, Egretta caerulea. Dormitator maculatus is a new host for all helminth species reported, and the Alvarado lagoonal system is a new location for these parasite relationships. The prevelance of the 2 most commonly occurring parasites, C. complanatum and N. golvani, was high throughout the year (\u3e 60% and \u3e 43%, respectively). Intensity of infection was highest for C. complanatum in May (92 worms/host) and for N. golvani in October 1993 (33.8 worms/host). The trophic position and habits of D. maculatus contributes to recruitment of trematode and nematode larval stages

Trophic Comparison of Two Species of Needlefish (Belonidae) in the Alvarado Lagoonal System, Veracruz, Mexico

We compared the diets of Atlantic needlefish, Strongylura marina, and redfin needlefish, Strongylura notata, in the Alvarado lagoonal system, Veracruz, Mexico, and analyzed diet breadth and trophic overlap between the species. All fishes were collected monthly from June 2000 to July 2001 at twelve sampling stations. A total of 74 intestinal tracts from S. marina were analyzed. The diet of S. marina consisted of 25 prey types with fish being the dominate prey. In eighty-nine digestive tracts examined from S. notata, the diet consisted of 29 prey types with the dominant prey including fishes, penaeid shrimp, polychaetes, and hymenopteran insects. There was moderate diet overlap (α = 0.4903) between S. marina and S. notata in the rainy season, while there was little diet overlap between species during the “nortes” (α = 0.1037) or dry (α = 0.1675) season. There was reduced niche breadth in both S. marina and S. notata during the “nortes” (BA = 0.175 and 0.105, respectively) and dry (BA = 0.128 and 0.173, respectively) seasons, with niche breadth values being higher for both species during the rainy season (BA = 0.254 and 0.296, respectively)

Acute Kidney Injury and Acute Liver Failure in Leptospira Infection and Weil’s Syndrome

Leptospirosis is considered a zoonosis acquired predominantly from contaminated surfaces and water, more commonly in emerging countries with limited sanitary conditions. Leptospira in the host unleashes an immune response that explains the symptoms and clinical signs; once it reaches the kidney and liver tissue, it can manifest with alterations that lead to acute and chronic diseases in both organs. Weil’s syndrome is the best known clinical manifestation with jaundice and acute kidney injury that could lead to multiple organ failure and death. For its diagnosis, there are simplified scores such as the SPiRO score, the microbiological criteria by microscopy or serological tests; the treatment focuses on antibiotics and, if necessary, provides organic support until the infection is curtailed. The purpose of this review was to address the impact of Leptospira infection on the kidney and liver, the mechanisms of organ damage, the clinical presentation, and diagnosis and management of this disease

Long-Term Fish Assemblage Dynamics of the Alvarado Lagoon Estuary, Veracruz, Mexico

The fish assemblages of Alvarado Lagoon Estuary (a complex of coastal lagoons in the state of Veracruz, Mexico) have been surveyed intermittently by different researchers over the last 40 years. Assessing longterm trends in fish assemblage composition for this ecosystem is problematic due to differences in sampling efforts among the survey periods (1966–1968, 1987–1988, 1989, 1989–1990, 1990–1991 and 2000–2001) and by the inherent ecological variability of estuaries. To overcome these data limitations and better understand fish assemblage change over time, we used robust, simulation-based analyses to compare collections from the different surveys. The 107 fish species collected from the Alvarado Lagoon Estuary in these surveys represent 4 ecological guilds: marine stenohaline, marine euryhaline, estuarine, and freshwater fishes. The occurrence frequency of fish species representing each guild did not change significantly among the survey periods: the chi-square deviation statistic ( 2 = 8.53) was not significantly larger than the average value for 1000 simulated matrices ( 2 = 138.64; P = 1.00). A non-metric multidimensional scaling (MDS) based on Bray-Curtis similarities of fish species presenceabsence data showed that the 1966–1968 survey period was the least similar to the other survey periods. For the 1966–1968 survey, the range of Bray-Curtis inter-survey similarities was 40.4–58.6 (n = 5). By comparison, the remaining range of inter-survey similarities was 61.5–81.7 (n = 10). Average taxonomic distinctness (Δ+) and variation in taxonomic distinctness (Λ+), two sample size-independent measures of diversity, were calculated for all survey periods. Although Δ+ and Λ+ for all survey periods were within the simulated 95% confidence limits for expected values, these values for the 2000–2001 survey period were less than the average Δ+ and Λ+ values for the entire species pool. This suggests that the fish assemblage collected during the latest survey reflects a loss of both widespread higher taxa (reduced Δ+) and that the higher taxa lost are those with only a few representative species in the assemblage (reduced Λ+). These assemblage data show that fish assemblages of Alvarado Lagoon Estuary have not experienced significant changes over 40 years, but differences among the earliest (1966–1968), the latest (2000–2001), and the remaining survey periods indicate a recent decline in diversity
