Dragonfly Production and Prey Turnover

Annual production was calculated for three dominant larval odonate populations (Ladona deplanata, Epitheca spp., and Celithemis fasciata) coexisting in the littoral zone of an abandoned farm pond. Dragonfly populations and their prey were collected simultaneously with an Ekman grab at 2-wk to 1-mo intervals. Production for each dragonfly species was calculated using both the Allen curve method and the removal-summation method. Annual production for the three dominant species was 6 g/m2 (dry wt), and total odonate production was estimated as 8 g/m2. Weekly odonate production was consistently > 0.3 g/m2 from July through September. With a mean annual standing stock of 2 g/m2, the odonate annual turnover ratio (TR) is 4. Weekly TRs were highest during summer months, generally declining as individual size increased. From back calculations of the amount of food required to feed the odonates, it was esti- mated that a minimal value of annual prey production was 18 g/m2 and a minimal estimate of weekly prey production in the summer months was almost 1 g/m2. With an observed prey standing stock of 0.6 g/m2, this would necessitate an annual prey TR of 30 and a weekly summer TR > 1. Since such an indirect method of calculating prey production does not account for other sources of prey mortality such as fish predation and emergence, the TRs are considered to be minimum values, perhaps only half of actual values. These relatively high TR values agree quite well with estimates based upon the amount of food required to sustain fish predators. The significance of these estimates made using indirect methods is that they are considerably higher than estimates made using more traditional direct methods. An attempt is made to resolve this discrepancy by examining sources of error associated with both approaches. Furthermore, since odonates have a standing stock frequently two to three times that of their prey and a large daily consumption capacity, I suggest that prey are saved from annihilation because they can find sufficient refuges.
Fast Algorithms for Discovering the Maximum Frequent Set

Discovering frequent itemsets is a key problem in important data mining applications, such as the discovery of association rules, strong rules, episodes, and minimal keys. Typical algorithms for solving this problem operate in a bottom-up breadth-first search direction. The computation starts from frequent 1-itemsets (minimal length frequent itemsets) and continues until all maximal (length) frequent itemsets are found. During the execution, every frequent itemset is explicitly considered. Such algorithms perform reasonably well when all maximal frequent itemsets are short. However, performance drastically decreases when some of the maximal frequent itemsets are relatively long. We present a new algorithm which combines both the bottom-up and the top-down searches. The primary search direction is still bottom-up, but a restricted search is also conducted in the top-down direction. This search is used only for maintaining and updating a new data structure we designed, the maximum frequent candidate set. It is used to prune candidates in the bottom-up search. A very important characteristic of the algorithm is that it does not require explicite examination of every frequent itemset. Therefore the algorithm performs well even when some maximal frequent itemsets are long. As its output, the algorithm produces the maximum frequent set, i.e., the set containing all maximal frequent itemsets, thus specifying immediately all frequent itemsets. We evaluate the performance of the algorithm using well-known synthetatic benchmark databases and real-life census and stock market databases. The improvement in performance can be up to several orders of magnitude, compared to the best current algorithms.
Bspace: a group workspace over the Ethereum blockchain with off-blockchain storage

Recently, to store a large amount of data for the blockchain decentralized applications, off-blockchain data storage techniques interworking with blockchain have emerged. However, these off-blockchain data storage techniques essentially cause the issue that it is difficult to control the user authentication and the access rights for each user outside the associated blockchain. In this paper, we introduce an implementation technique for supporting group workspaces based on the Ethereum blockchain, which provides secure file management among group users. To store large size files in group workspaces, a system structure is also being proposed where the Ethereum blockchain can stably interwork with the associated off–blockchain storage. Also, based on the file access rights stored in the Ethereum blockchain, we propose a systematic access control process for files shared among group members in the off-blockchain storage. In addition, to show the validity of the proposed technique, we present an Ethereum decentralized application called Bspace for using group workspaces interworking with off-blockchain storage.
Impact de la démographie médicale en Dordogne sur les passages aux Urgences du Centre Hospitalier de Périgueux : étude prospective réalisée du 17 octobre 2016 au 30 octobre 2016 à propos de 787 passages

Introduction : la Dordogne est un des plus grand desert medical du pays avec un effectif de medecins generalistes reduit de 14% depuis 2007. En parallele, en France et en Dordogne le nombre de passage aux urgences ne cesse d’augmenter avec un accroissement de 3,5% en moyenne par an. Objectifs : evaluer l’impact de la desertification medical chez les patients se rendant aux urgences et determiner les modalites des passages aux urgences. Materiel et methode : il s’agit d’une etude prospective realisee a l’aide d’un questionnaire rempli pour tout patient de plus de 18ans, non reconvoque, venant aux urgences de l’hopital de Perigueux entre le 17 et 30 octobre 2016. Deux groupes de demographie medicale ont ete definis : elevee (>8MG/10000habitants) (DME), faible (<8MG/10000hab) (DMF). Resultats : 787 questionnaires ont ete analyses. 65% des patients etaient du groupe DME dont 78,5% vivaient a moins de 15km de l’hopital. Les patients du groupe DMF sont proportionnellement plus « graves » mais ceux du groupe DME viennent plus directement aux urgences (61,3% vs 38,7%, p<0,001). 10,9% des patients issus d’une zone DME n’ont pas de medecin traitant declare contre 4,8% dans les zones DMF. La demographie medicale n’influe pas sur les horaires et jours de passage aux urgences. Conclusion : la desertification medicale n’impacte pas directement les passages aux urgences, au con-traire, les patients des zones desertiques ont plus de contact medical prealable a leur venue alors que les patients des fortes demographies medicale, vivant proche des urgences, s’y rendront plus directement.
Redescription of the holotype of Chanaresuchus bonapartei Romer, 1971 (Archosauriformes: Proterochampsidae) from the Upper Triassic rocks of the Chañares Formation of north-western Argentina

Proterochampsids are one of the several diapsid groups that originated, flourished and became extinct during the Triassic Period. The current fossil record of this group indicates that its species were restricted to continental assemblages of the early Late Triassic of South America. The recent description of new rhadinosuchine proterochampsid specimens from the Chañares Formation (early Carnian, Argentina) increased the morphological diversity of the group and cast doubts on their current taxonomic scheme. Previous authors have pointed out that available diagnoses do not allow specimens to be referred unambiguously to the different rhadinosuchine species. Here we redescribe, figure and compare in detail the holotype of one of these rhadinosuchine species, Chanaresuchus bonapartei from the Chañares Formation. The new information provided here allows us to discuss the degree of post-mortem deformation present in the specimen and check the character scorings for the proterochampsid species sampled in the most comprehensive phylogenetic data set currently available for Permo–Triassic archosauromorphs. Our new cladistic analyses find stronger support than previous studies for the monophyly of Rhadinosuchinae and the clades that include Doswelliidae + Proterochampsidae and Tropidosuchus + Rhadinosuchinae. Doswelliids are recovered within Proterochampsidae, as the sister taxon to the genus Proterochampsa, in some analyses under implied weights. Some characters present a phylogenetic signal consistent with the latter grouping, but one additional step is required to force it in the analysis under equal weights. We consider that the new anatomical and phylogenetic information provided here is a step towards a necessary taxonomic revision of Rhadinosuchinae and further research on the interrelationships of proterochampsian archosauriforms.
Ventral striatal atrophy in Alzheimer's disease : exploring a potential new imaging marker for early dementia

The striatum plays a central role in the limbic system and the cholinergic system, which are both affected in AD. Therefore the striatum can be considered a key candidate structure to be affected early in the disease. Part one of this thesis bundled the results of several volumetric and morphometric structural MRI studies of the striatum in older people and especially in patients with AD. Identifying pathological (focal) brain atrophy is, however, complex and a simple estimation of brain structure volumes of an individual patient does not lead to a diagnosis but needs to be assessed relative to group volumes and premorbid brain size. Therefore, in part two of this thesis two large population studies were included that focused on improving our understanding of the physiologic variability of brain structure and degeneration.
Effects of Langevin friction and time steps in the molecular dynamics simulation of nanoindentation

ABSTRACT In the simplest form of molecular dynamics (MD), the system evolves according to Newton's equations of motion with its total energy conserved. Moreover, to model systems at constant temperatures, a modified set of equations of motion, called a thermostat, can be used. Langevin thermostat with one parameter called the Langevin friction coefficient is a popular thermostat, but problems may arise when it is applied to nonequilibrium systems without tuning the friction coefficient. Additionally, the size of MD time step also plays a pivotal role in determining accuracy and efficiency. In this study, we consider the effects of time step and Langevin friction on MD simulations. First, we evaluate the effectiveness of the Langevin thermostat for different combinations of time step and friction coefficient. Second, nanoindentation of Nickel crystals are carried out for five different combinations of Langevin friction and time steps. The simulation results reveal noticeable differences in mechanical properties as the dynamics changes from a constant energy to constant temperature simulations with increasing friction coefficients. The structural characteristics are also quantified using the common neighbour analysis, centrosymmetry parameter and dislocation analysis, all of which show a similar trend of more atoms being deformed with increasing friction.
Gray-box virtual sensor of the supply air temperature of air handling units

Building automation system uses several networks of sensors for continuous monitoring of building control systems for energy-efficient operation. Physical sensors are costly and need frequent calibration. The accurate measurement of supply air temperature from the air handling units (AHUs) has an important effect on the control of cooling coil, supply air temperature and supply airflow rate delivered to rooms. In the case when such a sensor gives erroneous measurements, a virtual sensor can replace temporarily the faulty sensor, and it can also be used for automated fault detection of HVAC systems. This article proposes two different gray-box (models A and B) for predicting the supply air temperature of air handling units that were developed and tested using the measurements from two buildings. The models require the measurement of three variables (mixed air temperature, cooling coil valve signal, and chilled water inlet temperature). The results of both models are discussed and compared. A sliding window approach for cross-validation of the models was also carried out. The developed gray-box models A and B could be integrated into BAS for virtual measurement, virtual calibration, and fault detection in HVAC systems.

Women in the local political system in Italy. A longitudinal perspective

ABSTRACT The gap between men and women in the formal enjoyment of political rights, and the low level of women’s active participation in political life, even if it is common to several western democracies, is in Italy especially apparent, due to the high degree of gender inequality at various levels. The number of women in representative institutions tends to be inversely related to the centrality of the institutions, with numbers increasing with the move from the national to the local (regional, provincial and municipal) levels. This is the quantitative effect of ‘bringing politics close to home’ – through a process of decentralization of policies affecting women’s rights and empowerment (in the labour market, education and health), particularly evident in Italy from the 1970 s and especially from 2000 – that brought increasing female representation in meso-level institutions. Starting from an essential link between quantity and quality, the article examines in depth the configuration of women’s representation at local level through a longitudinal perspective based on data concerning elected women in local institutions from 1986 to 2019.
Low-Complexity Multiuser Receiver for Massive Hybrid Array mmWave Communications

In this paper, we study the low complexity reception of multiuser signals in uplink millimeter wave (mmWave) communications using a partially connected hybrid antenna array. Exploiting the mmWave channel property, we propose a low-complexity user-directed multiuser receiver with three novel schemes for allocating subarrays to users. This receiver only requires the knowledge of angles-of-arrival (AoAs) for dominating paths and a small amount of equivalent channel information instead of perfect channel state information. For comparison, we also derive a successive interference cancellation-based solution as a performance benchmark. We design two types of reference signals with the channel estimation method to enable efficient and simple estimation for AoA and equivalent baseband channel. Also, we provide analytical results for the performance of the AoA estimation, using the lower bounds of mean square errors in line-of-sight dominated mmWave channels. The simulation results validate that the proposed channel estimation method is effective when employed in combination with a zero-forcing equalizer.
Dynamics of Arthropod Filiform Hairs. III. Flow Patterns Related to Air Movement Detection in a Spider (Cupiennius salei KEYS.)

In previous studies we related the mechanical properties of spider trichobothria to a generalized mathematical model of the movement of hair and air in filiform medium displacement receivers. We now present experiments aimed at understanding the complex stimulus fields the trichobothrial system is exposed to under natural conditions. Using the elicitation of prey capture as an indicator and a tethered humming fly as a stimulus source, it has been shown that the behaviourally effective range of the trichobothrial system in Cupiennius salei Keys. is approximately 20 cm in all horizontal directions. Additionally, the fly still elicits a suprathreshold deflection of trichobothria while distanced 50-70 cm from the spider prosoma. To gain insight into the fluid mechanics of the behaviourally effective situation we studied: first, undisturbed flow around the spider in a wind tunnel; second, background flow the spider is exposed to in the field; and third, flow produced by the tethered flying fly. 1. The motion of air around a complex geometrical structure like a spider is characterized by an uneven distribution of flow velocities over the spider body. With the flow approaching from the front, both the mean and r.m.s. values are higher above the legs than above the pro- and opisthosoma; the velocity in the wake behind the spider, however, is markedly decreased. The pattern of these gradients is more complicated when the spider's horizontal orientation is changed with respect to the main flow direction. It introduces asymmetries, for exmple, increased vortical, unsteady flow on the leeward compared with the windward side. 2. Sitting on its dwelling plant and ambushing prey in its natural habitat, the background air flow around Cupiennius is characterized by low frequencies ( $^{-1}$ with less than 15% r.m.s. fluctuation). 3. The distinctive features of a biologically significant air flow (for example, that produced by the humming fly) seem to be a concentrated, i.e. directional unsteady, high speed flow of the order of 1 m s $^{-1}$ , and a relatively broad frequency spectrum containing frequencies much higher than those of the background flow. For a spider, sitting on a solid substrate (a leaf of a bromeliad, for example), air speed just above the substrate increases and thus provides higher sensitivity when compared to a spider in a orb web, which is largely transparent to the airflow. The flow patterns stimulating the ensemble of the trichobothria contain directional cues in both the undisturbed flow and the flow due to prey cases.
Emerging Functions of Plant Serine/Arginine-Rich (SR) Proteins: Lessons from Animals

Abstract Serine/arginine-rich (SR) proteins are widely found in higher eukaryotes, including metazoans and plants. They form a major family of essential splicing factors that function in both constitutive splicing (CS) and alternative splicing (AS). Some SR proteins can also shuttle between the nucleus and cytoplasm and have roles beyond splicing. The activities of SR proteins are required for many living organisms to maintain normal growth and development. Although SR genes have been identified in numerous plants, they are less studied than those found in animals. The results of existing research suggest that plant SR proteins share many similar properties with their animal counterparts. However, plants generally have a higher number of SR proteins that display largely redundant functions under normal conditions but participate in specific stress responses. Moreover, many animal and plant SR genes are alternatively spliced and can be regulated by themselves or other SR proteins. These AS events, often coupled to nonsense-mediated decay (NMD), enable a mechanism for protein amount control under different conditions but sometimes also lead to translated protein isoforms with different functions. Here, we summarize the key findings of SR proteins in animals and plants and compare the essential characteristics of SR studies in these two research areas.
Wireless Body Area Networking: Joint Physical-Networking Layer Simulation and Modeling

An electronic device equipped with sensors and antennas is the main part of the wireless body area networking (WBAN). Such a device is placed near human body and it usually works in a populated environment with many surrounding objects (e.g., building walls). The human body and the objects can change the radiation characteristics of the antenna and impact the performance of the wireless communication system. The wireless com- munication system’s performance is also affected by the networking layers established on top of the physical layer. Therefore, any designing method for WBAN application should be pervasive, offering a joint physical-networking layer simulation and modeling strategy. To this end, in this chapter, a comprehensive simulation and modeling method is presented. First, antenna design limitations and challenges for wireless body area networking are studied with emphasis on evaluating the antenna’s performance near the human body. Then, the antenna miniaturization techniques to reduce the antennas’ dimension are reviewed. Later, a system level analysis and modeling are used to study short-range communication between the wearable antennas with remote nodes using IEEE 802.11g wireless networking protocol.

All animals between 2.5-12 years were categorized according to age (i.e. heifer, young cow, and old cow). A medium-sized follicle (φ 3-8 mm.) had the greatest distribution among the various size classes (p≤ 0.05), and the mean of oocytes collected from each group was not significantly different. Postthawed survival was 60.78, 53.70 and 57.50%, with a cleavage rate of 38.71, 37.93 and 39.13%, and a blastocyst embryo of 6.45, 3.45 and 4.35% among heifers, young cows and old cows, respectively, which was significantly less than the fresh control group and solution control group (p≤ 0.05). The present study suggests that OPU in Thai indigenous beef cattle without hormonal pre-stimulation can be routinely done for an extended period of time. The age of donor does not affect the number and quality of oocytes aspirated, post-thawed viability and the number of embryos developing after IVF. Keywords : cryopreservation, GMP, IVF, OPU
