    Abstract The reproductive output of Malaclemys terrapin (Diamond-backed Terrapin) is highly variable across its geographic range. While much of the literature is based on populations from the Atlantic coast of the United States, little reproductive-output data exists for the Gulf of Mexico populations. We captured female Diamond-backed Terrapins in southwestern Louisiana and assessed their reproductive output using radiographic- and ultrasound-imaging techniques. X-rays identified that average clutch size was 7.2 and average egg width was 21.9 mm. We revealed a positive relationship between female size (plastron length) and both clutch size and egg width, but no relationship between egg size and clutch size. Ultrasound imaging in a subset of individuals revealed large pre-ovulatory follicles and fully shelled eggs concurrently in females, indicating the potential for at least 2 clutches annually in this region. Our results suggest Diamond-backed Terrapins in southwestern Louisiana show variation in reproductive output compared to other populations at similar latitudes, indicating the need for additional study within and between populations in the region.

    Abstract Populations of wide ranging ectotherms often exhibit variation in traits that are influenced by local environmental conditions. Although the gopher tortoise, Gopherus polyphemus, is well studied in pine flatwoods habitats across their range, little attention has been given to coastal populations existing in the southern extreme portion of the range. We examined the reproductive physiology of a coastal dune population in southwest Florida to determine if reproductive cycles vary across populations. Here we present the first year-round sex hormone profiles for a wild population of gopher tortoises. Male testosterone concentrations varied across the year (F

    Abstract A new paradigm for data-driven, model-agnostic new physics searches at colliders is emerging, and aims to leverage recent breakthroughs in anomaly detection and machine learning. In order to develop and benchmark new anomaly detection methods within this framework, it is essential to have standard datasets. To this end, we have created the LHC Olympics 2020, a community challenge accompanied by a set of simulated collider events. Participants in these Olympics have developed their methods using an R&D dataset and then tested them on black boxes: datasets with an unknown anomaly (or not). Methods made use of modern machine learning tools and were based on unsupervised learning (autoencoders, generative adversarial networks, normalizing flows), weakly supervised learning, and semi-supervised learning. This paper will review the LHC Olympics 2020 challenge, including an overview of the competition, a description of methods deployed in the competition, lessons learned from the experience, and implications for data analyses with future datasets as well as future colliders.

    Abstract The detoxificatiooe of hydrogen sulfide (H(2)) by a heme catalyzed oxidation was examined as part of an on-going study of H(2)S toxicity. Interlocking O(2) absorption and sulfide depletion data indicate that both oxyhemoglobin and methemoglobin are effective catalytic agents. Although the latter is more efficacious, the life time of excess sulfide in the presence of oxygen and either of the above is of the order of minutes. It has also been established that the formation of methemoglobin following nitrite administration occurs preferentially under oxygen poor conditions. Under an atmospheric or oxygen enriched environment, which favors sulfide depletion, the nitrite retards sulfide oxidation. Thus nitrite as an antidote for acute H(2) intoxication can only be effective within the first few minutes after the exposure, a which time resuscitation and/or ventilation of the victim is likely to produce conditions in which the nitrite actually slows sulfide removal.

    Abstract The absorption of hydrogen sulfide (H2S) gas by sciatic nerve bundles from Rana pipiens produces an anaesthetic effect of short duration. Subsequent compound action potential (CAP) levels are higher than before exposure while the conduction velocity (CV) shows only small variation. Exposure to hydrogen cyanide (HCN) gas produces declining CAP and CV levels. The effect of H2S on the CAP is faster than that of HCN and the recovery time is shorter, although there is evidence of permanent change. Unlike HCN there is no indication that H2S inhibits the energy metabolism of the nerve cells, except possibly when the nerves are exposed to extremely high sulfide concentrations. A mode of action for H2S is proposed.

    Abstract Sciatic nerve bundles from Rana pipiens were immersed in amphibian Ringer containing sulfide or cyanide. Subsequent examination of the compound action potential (CAP) revealed a distinct difference in the effects of these two anions. Whereas cyanide produced a nerve incapable of repeated firings, sulfide-treated nerves displayed an increased CAP which showed no tendency to diminish over extended stimulation periods.

    Abstract A study was conducted in Antigonish, Nova Scotia, to determine the extent to which acid rain related pollutants are present in indoor ambient air. The pollutant study included: fine (0 to 2.5 micron) and coarse (2.5 to 10 micron) particulates, sulphates, nitrates, acidity (H2SO4 and HNO3), SO2 and NO2. During the 3 1/2 month study, maximum levels of 173n equivalent/m3 fine sulphate and 55 n equivalent/m3 H2SO4 were recorded for outdoor air within the town site compared to corresponding values of 110 n equivalent/m3 and 13 n equivalent/m3 for indoor air. Based on back trajectory analysis, wind direction, and sulphuric acid content, it was postulated that local or medium range pollution sources are predominant in the winter while long range transport originating from the United States produces the major episodes when SW winds are persistent.
