Abstract:
From an experiment with ordinary dart tags, we have found evidence of the effect of fish-aggregating devices (FADs) and of islands on the movements of skipjack tuna (Katsuwonus pelamis) around the Solomon Islands. By fitting a fish movement model to the tag data, we were able to estimate mortality and movement parameters (including diffusivity), parameters of a function that models FAD attraction, and a separate parameter of island attraction. Diffusivity was high enough to effectively distribute fish throughout the island archipelago (approximately 150 000 km2) within a few months. Estimates of FAD parameters indicate that the presence of up to four or five FADs in an area approximately 50 × 50 km can reduce the propensity for skipjack to leave that area by approximately 50%, but that deploying additional FADs in such an area does not significantly increase their effectiveness in holding skipjack. Estimates of the island attraction parameter imply that the propensity of skipjack for movement away from the archipelago is less than half the propensity for movement within it.

Abstract:
Abstract This article presents a study of errors made by hearing adult L2 learners of Swiss German Sign Language (Deutschschweizerische Gebärdensprache, DSGS). As part of a statistical analysis of single-parameter errors, movement was found to be the parameter most susceptible to errors, followed by location, orientation, and handshape. An analysis of production errors with respect to combinations of manual parameters was also conducted, something that previously has not been undertaken. The parameter combination most frequently involved in errors was movement with location. Possible aspects contributing to the higher error rate for movement are suggested, among which are the inherent complexity of the movement parameter. Finally, the article discusses factors influencing the judgment of errors.

Abstract:
1. Several neurophysiological studies of the primary motor and premotor cortices have shown that the movement parameters direction, distance, and target position are correlated with the discharge of single neurons. Here we investigate whether the correlations with these parameters occur simultaneously (i.e., parallel processing), or sequentially (i.e., serial processing). 2. The single-unit data used for the analyses presented in this paper are the same as those used in our earlier study of neuronal specification of movement parameters. We recorded the activity of single neurons in the primary motor and premotor cortices of two rhesus monkeys (Macaca mulatta) while the animals performed reaching movements made in a horizontal plane. Specifically, the animals moved from a centrally located start position to 1 of 48 targets (1 cm2) placed at eight different directions (0-360 degrees in 45 degrees intervals) and six distances (1.4-5.4 cm in 0.8-cm increments) from the start position. 3. We analyzed 130 task-related cells; of these, 127 (99 in primary motor cortex, 28 near the superior precentral sulcus) had average discharges that were significantly modulated with the movement and were related to movement direction, distance, or target position. To determine the temporal profile of the correlation of each cell's discharge with the three parameters, we performed a regression analysis of the neural discharge. We calculated partial R2s for each parameter and the total R2 for the model as a function of time. 4. The discharge of the majority of units (73.2%) was significantly correlated for some time with all three parameters. Other units were found that correlated with different combinations of pairs of parameters (21.3%), and a small number of units appeared to code for only one parameter (5.5%). There was no obvious difference in the presence of correlations between cells recorded in the primary motor versus premotor cortices. 5. On average we found a clear temporal segregation and ordering in the onset of the parameter-related partial R2 values: direction-related discharge occurred first (115 ms before movement onset), followed sequentially by target position (57 ms after movement onset) and movement distance (248 ms after movement onset). Some overlap in the timing of the correlation of these parameters was evident. We found a similar sequential ordering for the latency of the peak of the R2 curves (48, 254, and 515 ms after movement onset, respectively, for direction, target position, and distance).(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract:
The aim of the present study was to investigate whether the fusimotor control of muscle spindle sensitivity may depend on the movement parameter the task is focused on, either the velocity or the final position reached. The unitary activities of 18 muscle spindle afferents were recorded by microneurography at the common peroneal nerve. We compared in two situations the responses of muscle spindle afferents to ankle movements imposed while the subject was instructed not to pay attention to or to pay attention to the movement, both in the absence of visual cues. In the two situations, three ramp-and-hold movements were imposed in random order. In one situation, the three movements differed by their velocity and in the other by the final position reached. The task consisted in ranking the three movements according to the parameter under consideration (for example, slow, fast, and medium). The results showed that paying attention to movement velocity gave rise to a significant increase in the dynamic and static responses of muscle afferents. In contrast, focusing attention on the final position reached made the muscle spindle feedback better discriminate the different positions and depressed its capacity to discriminate movement velocities. Changes are interpreted as reflecting dynamic and static gamma activation, respectively. The present results support the view that the fusimotor drive depends on the parameter the task is focused on, so that the muscle afferent feedback is adjusted to the task requirements.

Abstract:
In this thesis, we present a dynamical systems analysis of models of movement coordination, namely the Haken-Kelso-Bunz (HKB) model and the Jirsa-Kelso excitator (JKE). The dynamical properties of the models that can describe various phenomena in discrete and rhythmic movements have been explored in the models' parameter space. The dynamics of amplitude-phase approximation of the single HKB oscillator has been investigated. Furthermore, an approximated version of the scaled JKE system has been proposed and analysed. The canard phenomena in the JKE system has been analysed. A combination of slow-fast analysis, projection onto the Poincare sphere and blow-up method has been suggested to explain the dynamical mechanisms organising the canard cycles in JKE system, which have been shown to have different properties comparing to the classical canards known for the equivalent FitzHugh-Nagumo (FHN) model. Different approaches to de fining the maximal canard periodic solution have been presented and compared. The model of two HKB oscillators coupled by a neurologically motivated function, involving the effect of time-delay and weighted self- and mutual-feedback, has been analysed. The periodic regimes of the model have been shown to capture well the frequency-induced drop of oscillation amplitude and loss of anti-phase stability that have been experimentally observed in many rhythmic movements and by which the development of the HKB model has been inspired. The model has also been demonstrated to support a dynamic regime of stationary bistability with the absence of periodic regimes that can be used to describe discrete movement behaviours.

Parameter search in an agent-based model of pedestrian movement in retail environments is part of a research effort by data-driven architecture in the Cognitive Machine Group at the MIT Media Lab. The approach pursued in this thesis is agent-based modeling, with an ultimate goal to use generative behaviors in agents to study effects of architectural and managerial decisions on retail environments. In this thesis, I designed and implemented an agent training module as a part of a software system which simulates and learns patterns of human pedestrian movement in retail environments. This thesis covers two different components: (1) the implementation of a hill-climbing training module and (2) a pedestrian path comparison metric. To measure the module's performance, the system is tested against video sequences collected from the actual retail environment.

Abstract:
This study focuses on evaluating a system containing five different mappings of physical movement parameters to auditory parameters. Physical parameter variables such as size, location, among others, were obtained by using a motion tracking system, where the two hands of the user would work as rigid bodies. Translating these variables to auditory parameter variables gave the ability to control different parameters of MIDI files. The aim of the study was to determine how well a total of five participants, all with prior musical knowledge and experience, could adapt to the system concerning both user generated data as well as overall user experience. The study showed that the participants developed a positive personal engagement with the system and this way of audio and music alteration. Exploring the initial mappings of the system established ideas for future development of the system in potential forthcoming work.

Abstract:
In this thesis I do a comparative study between the Brazilian Portuguese Grammar (henceforth BP) and European Portuguese Grammar (henceforth EP) concerning to the word order, more specifically, with respect to the subject order in relation to the verb in finite declarative phrases. One defends that Verb-Subject order (VS) has been lost in the first language in (in)transitive contexts due a parametric change in the marking of Null Subject Parameter caused by weakness of AGR, what implies to consider that BP is losing the characterization of a prototypical null subject language as the EP for become a non-prodrop subject language as English. In this order, in inaccusative contexts, the visible morphologically agreement between a verbal inflection and the post-verbal DP is generally not observed and this DP can also be definite or indefinite, unlike what is proposed by Belletti s approach. Futhermore, researches have assumed that the subject position with respect to the verb comes from the fact of the syntax be conditioned by discoursive constraints. Therefore, with respect to these aspects, the goals of this research are: a) to develop an analysis about VS order in both grammars, considering the implications of the AGR richness for the position of the subjects ; b) to characterize this richness from the rediscussion of some theoretical proposals; c) to show counter-evidences to the proposal of that the word order codifies the informational structure; d) to explain the possibility of the non-visible morphologically agreement between the post-verbal DP and the verbal inflection in inaccusative contexts and its implications for the type of mechanism concerned to the nominative Case assignment and e) to argue against the universality of the Definiteness Efect on the post-verbal DP. To develope this study, the analysis bases itself on Pricinciples and Parameters, and the Distributed Morphology frameworks. The sentence structures are results from introspection data. During this research, it was possible to conclude that rich AGR that licences and identifies referential null subjects in null subject languages has no correlation with rich AGR that causes the verb movement in the syntax, and that preverbal subjects occupy an A-position in BP and in EP, unlike what is generally proposed. Futhermore, the different behaviour of VS order observed among these languages receives explanatory support from the type of syntactic output generated by each grammar in particular but not from discoursive constraints. With respect to the order in which there is no visibility of morphological agreement between the verbalinflection and the post-verbal DP in inaccusative contexts, I argue that it is a pseudo- VS order, in which Definiteness Efect does not act on.
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
Nesta tese realizo um estudo comparativo entre a gramática do português brasileiro (doravante PB) e a do português europeu (doravante PE) no que diz respeito à ordem dos constituintes, mais especificamente, do sujeito em relação ao verbo em frases declarativas finitas. Tem-se defendido que a ordem Verbo-Sujeito (VS) tem sido perdida na primeira língua em contextos (in)transitivos em virtude de uma mudança paramétrica na marcação do Parâmetro do Sujeito Nulo ocasionada pelo enfraquecimento de AGR, o que implica considerar que o PB está deixando de ser uma língua de sujeito nulo prototípica como o PE para tornar-se uma língua de sujeito não-nulo como o inglês. Nessa ordem, em contextos inacusativos, a concordância morfologicamente visível entre a flexão verbal e o DP pós-verbal, em geral, não é observada e, ainda, esse DP pode ser definido ou indefinido, ao contrário do que é proposto pela análise belletiana. Ademais, estudos têm assumido que a posição do sujeito em relação ao verbo decorre do fato de a sintaxe estar a serviço de requerimentos de ordem discursiva. Portanto, face a esses aspectos, os objetivos desta pesquisa são: a) desenvolver uma análise sobre a ordem VS em ambas as gramáticas, levando em conta as implicações da riqueza de AGR para a posição dos sujeitos; b) caracterizar essa riqueza , a partir da rediscussão de algumas propostas teóricas; c) apresentar contra-evidências à proposta de que a ordem dos constituintes codifica a estrutura informacional; d) explicar a possibilidade de concordância morfologicamente não-vísível entre o DP pós-verbal e a flexão verbal em contextos inacusativos e suas implicações para o tipo de mecanismo relacionado à atribuição de Caso nominativo e e) argumentar contra a universalidade do Efeito de Definitude sobre o DP pós-verbal. Para a realização desse estudo, a análise fundamenta-se no arcabouço teórico do Modelo de Princípios e Parâmetros e da Morfologia Distribuída, sendo as estruturas frasais resultados de dados de introspecção. No decorrer desta pesquisa, é plausível concluir que AGR rico que licencia e idendifica sujeitos nulos referenciais em línguas de sujeito nulo não tem a ver com AGR rico que motiva o movimento do verbo na sintaxe, e que sujeitos pré-verbais ocupam uma posição-A no PB e no PE, ao contrário do que é comumente proposto na literatura. De mais a mais, o comportamento diferenciado da ordem VS atestado entre essas línguas ganha suporte explicativo no tipo de output sintático gerado por cada gramática em particular e não em requerimentos de ordem discursiva. No que concerne à ordem em que não há visibilidade da concordância morfológica entre a flexão-verbal e o DP pós-verbal em contextos inacusativos, argumento que seja uma pseudo-ordem VS , não sendo atuante sobre esse DP o Efeito de Definitude.

Full text
Abstract:
This thesis sets out to test the Full Transfer Full Access hypothesis (FTFA), which claims (i) that second language (L2) learners start out with the parameter settings instantiated in their first language (L1) grammars ('full transfer') and (ii) that they can subsequently reset parameters to the target L2 settings where these differ from the L1 settings, provided the required (triggering) positive evidence is available in the L2 input ('full access').
Three studies on the L2 acquisition of two verb movement parameters, the V2 parameter and the Split-IP parameter (SIP), are reported. The first study investigates 'full access', testing whether English-speaking learners of Afrikaans, who started acquiring the L2 in early childhood and are thus child L2 learners, can reset the two parameters. The second study investigates 'full transfer' and 'full access' by testing whether English-speaking and German-speaking learners start out with different settings of the two parameters and whether the English-speaking learners can reset the parameters. All participants in this study are adult L2 learners, which facilitates a comparison of child L2 acquisition (first study) with adult L2 acquisition. The third study investigates whether Afrikaans-speaking learners of French can acquire knowledge of the ungrammaticality of certain construction types that are allowed in their L1 but not in the L2 (although the languages share the same parameter setting), despite the fact that there seems to be no positive evidence to this effect in the L2 input. It is argued that, taken together, the studies provide evidence in support of the FTFA.
The original contribution of this thesis lies in (i) investigating both verb movement parameters (instead of only one), (ii) providing a thorough discussion of the relevant syntactic properties of Afrikaans, (iii) investigating the L2 acquisition of Afrikaans, and (iv) addressing the question of how learners go about acquiring a parameter setting ([+SIP]) in cases where both the L1 and the L2 share the parameter setting but the L1 exhibits a superset of the properties exhibited by the L2.

Full text
Abstract:
This book develops a minimalist approach to cross-linguistic morphosyntactic variation. The principal claim is that the essential insight of the principles-and-parameters approach to variation can be maintained—albeit in a somewhat different guise—in the context of the minimalist programme for linguistic theory. The central idea is to organize the parameters of Universal Grammar (UG) into hierarchies which define the ways in which properties of individually variant categories and features may act in concert. The hierarchies define macro-, meso-, and microparameters as a function of the position of parametric options in a given hierarchy. A further leading idea, which is consistent with the overall goal of the minimalist programme to reduce the content of UG, is that the parameter hierarchies are not directly determined by UG. They are emergent properties stemming from the interaction of the three factors in language design. Universal Grammar, the first factor, provides a template for the underspecification of the formal features in terms of which parameters are defined. The second and third factors determine the organization of these formal options into hierarchies: two third-factor effects (Feature Economy and Input Generalization) play a central role. Cross-linguistic variation in word order, null subjects, incorporation, verb-movement, case/alignment, wh-movement, and negation are all analysed in the light of this approach. This book represents a significant new contribution to the formal study of cross-linguistic morphosyntactic variation on both the empirical and theoretical levels.

Full text
Abstract:
This chapter posits a parameter hierarchy to capture micro-parametric variation in ergative (or rather non-accusative) alignment, building on the proposal that ergative is an inherent case, assigned by little vs. Initial parameters determine the distribution of this inherent case across instances of little v in a given language, sensitive to various thematic features, and subsequent dependent parameters determine further properties of ergative-assigning vs such as the presence of a movement trigger and the suppression of structural Case features. This gives rise to a number of distinct ergative types depending on the distribution of ergative case, the presence/absence of syntactic ergativity, and the source of absolutive case in transitive contexts. The resultant parameter hierarchy serves to restrict the space of variation, modeling a number of proposed implicational universals in this domain, and provides a potential solution to the subset problem in acquisition by encoding a notion of relative markedness.

Full text
Abstract:
Discontinuous structures produced by edge-fronting represent one distinctive feature of Latin regarding Romance. This difference follows from the head parameter: whereas Romance is consistently head-initial, Latin fluctuates between different settings as a result of its occupying an intermediate position in the gradual shift from head-finality to head-initiality. In turn, this difference in the head parameter is responsible for the observed variation in edge-fronting, since its setting determines the application of antilocality in constraining movement. Concretely, if head-finality is the output of a roll-up operation raising the complement to the specifier to the left of its head, suspension of antilocality constitutes a sine qua non for head-final languages like Latin. In Romance, by contrast, the head parameter is aligned with the head-initial setting such that roll-up (hence antilocal) movement never arises. This investigation thus derives from the different settings of the head parameter a concomitant parametrization in the role of antilocality.

Full text
Abstract:
The theoretical presumptions and some experimental calculations to analyse the speeds of the galaxies movements according to redshift measurements applying the Doppler effect are presented. The speed of the galaxy movement is treated as multidimensional continuous value, when values of the speed vector are calculated according to measurements of the redshift parameter z at corresponding moments of the universe lookback time. The most reliable values of the galaxy speeds vector are calculated applying the least square method to the vector of z measurements and including the additional parameters to eliminate the possible systematic errors. The acceleration of the galaxy movement is calculated as a speed fluxion according to period of the adopted redshift signal frequency and as a speed change during the lookback time interval. The expressions of functions of the galaxies speeds and accelerations are received by the polynomial approximation, when values of the polynomial parameters are calculated by the least square method.

Full text
Abstract:
In light of widespread evidence of parameter instability in macroeconomic models, many time-varying parameter (TVP) models have been proposed. This paper proposes a nonparametric TVP-VAR model using Bayesian additive regression trees (BART). The novelty of this model stems from the fact that the law of motion driving the parameters is treated nonparametrically. This leads to great flexibility in the nature and extent of parameter change, both in the conditional mean and in the conditional variance. In contrast to other nonparametric and machine learning methods that are black box, inference using our model is straightforward because, in treating the parameters rather than the variables nonparametrically, the model remains conditionally linear in the mean. Parsimony is achieved through adopting nonparametric factor structures and use of shrinkage priors. In an application to US macroeconomic data, we illustrate the use of our model in tracking both the evolving nature of the Phillips curve and how the effects of business cycle shocks on inflationary measures vary nonlinearly with movements in uncertainty.

Zilberman, Mark. Methods to Test the “Dimming Effect” Produced by a Decrease in the Number of Photons Received from Receding Light Sources. Intellectual Archive, November 2020. http://dx.doi.org/10.32370/iaj.2437.

Full text
Abstract:
The hypothetical “Dimming Effect” describes the change of the number of photons arriving from a moving light source per unit of time. In non-relativistic systems, the “Dimming effect” may occur due to the growing distance of light sources moving away from the receiver. This means that due to the growing distance, the photons continuously require more time to reach the receiver, which reduces the number of received photons per time unit compared to the number of emitted photons. Understandably, the proposed “Dimming effect” must be tested (confirmed or rejected) through observations. a. This article provides the formula for the calculation of “Dimming effect” values using the redshift parameter Z widely used in astronomy. b. The “Dimming effect” can possibly be detected utilizing the orbital movement of the Earth around the Sun. In accordance to the “Dimming effect”, observers on Earth will view 1.0001 more photons per time unit emitted by stars located near the ecliptic plane in the direction of the Earth orbiting the Sun. And, in contrast, observers will view only 0.9999 photons per time unit emitted by stars located near the ecliptic plane in the direction opposite to the Earth orbiting the Sun. Calculating precise measurements of the same stars within a 6-month period can possibly detect this difference. These changes in brightness are not only for specific stars, as the change in brightness takes place for all stars near the ecliptic in the direction of the Earth’s orbit around the Sun and in the opposite direction. c. The “Dimming effect” can possibly be detected in a physics laboratory using a moving light source (or mirror) and photon counters located in the direction of travel and in the opposite direction. d. In theory, Dilation of time can also be used for testing the existence of the “Dimming effect.” However, in experiments on Earth this effect appears in only the 14th digit after the decimal point and testing does not appear to be feasible. e. Why is it important to test the “Dimming effect?” If confirmed, it would allow astronomers to adjust values of "Standard Candles" used in astronomy. Since “Standard Candles” are critical in various cosmological models, the “Dimming effect” can correct models and/or reveal and support new models. If it is proved that the “Dimming effect” does not exist, it will mean that the number of photons arriving per unit of time does not depend on the speed of the light source and observer, which is not so apparent.

Lenhardt, Amanda. Evidence on the Effectiveness of Covid-19 International Travel Measures. Institute of Development Studies, January 2022. http://dx.doi.org/10.19088/k4d.2022.054.

Full text
Abstract:
Evidence on the effectiveness of travel measures to prevent or slow the spread of Covid-19 and guidance on how and when to apply these measures is limited and the results are mixed. Given the social and economic disruptions that these measures can have, and their potential adverse effects on preventing the spread of the disease, WHO among others have cautioned implementing measures that are not supported by robust evidence. The scope of the search for this report was broad, covering all reported international travel restrictions to contain or slow the spread of Covid-19 and without geographical limitations. The results are therefore more general than restriction- or country-specific and more targeted studies may be omitted from the search due to these wide search parameters. There is general agreement across the literature that some form of travel restriction in the early stages of a disease or variant spread can lead to a slowing of the rate of infections in countries yet to be affected. The majority of studies conducted on travel restrictions adopt a modelling approach, and a systematic review conducted in December 2020 concluded that the quality of observational studies was low to very low (Bou-Karroum et al., 2021). Determining the specific effects of different travel measures is difficult as many studies examine the effects of combined measures. Few studies separate different types of restrictions and much of the modelling on international transmission rates uses data on the movements of people as a proxy for travel restrictions, therefore limiting the ability to observe how measures were implemented except for the timing of measures at different points in the pandemic. Limited country-level evidence was identified for this report and few global studies examine contextual factors that might affect the effectiveness of travel restriction measures. A targeted search for evidence on the effects of travel restrictions on different variants of Covid-19 did not reveal any studies making this distinction.

United States Department of Agriculture, January 2003. http://dx.doi.org/10.32747/2003.7587725.bard.

Full text
Abstract:
The original objectives of the approved proposal were: 1. To construct a YFP fused Arabidopsis cDNA library in a mammalian expression vector. 2. To infect the library into a host fibroblast cell line and to screen for new cytoskeletal associated proteins using an automated microscope. 3. Isolate the new genes. 4. Characterize their role in plants. The project was approved as a feasibility study to allow proof of concept that would entail building the YFP library and picking up a couple of positive clones using the fluorescent screen. We report here on the construction of the YFP library, the development of the automatic microscope, the establishment of the screen and the isolation of positive clones that are plant cDNAs encoding cytoskeleton associated proteins. The rational underling a screen of plant library in fibroblasts is based on the high conservation of the cytoskeleton building blocks, actin and tubulin, between the two kingdoms (80-90% homology at the level of amino acids sequence). In addition, several publications demonstrated the recognition of mammalian cytoskeleton by plant cytoskeletal binding proteins and vice versa. The major achievements described here are: 1. The development of an automated microscope equipped with fast laser auto-focusing for high magnification and a software controlling 6 dimensions; X, Y position, auto focus, time, color, and the distribution and density of the fields acquired. This system is essential for the high throughput screen. 2. The construction of an extremely competent YFP library efficiently cloned (tens of thousands of clones collected, no empty vectors detected) with all inserts oriented 5't03'. These parameters render it well representative of the whole transcriptome and efficient in "in-frame" fusion to YFP. 3. The strategy developed for the screen allowing the isolation of individual positive cDNA clones following three rounds of microscopic scans. The major conclusion accomplished from the work described here is that the concept of using mammalian host cells for fishing new plant cytoskeletal proteins is feasible and that screening system developed is complete for addressing one of the major bottlenecks of the plant cytoskeleton field: the need for high throughput identification of functionally active cytoskeletal proteins. The new identified plant cytoskeletal proteins isolated in the pilot screen and additional new proteins which will be isolated in a comprehensive screen will shed light on cytoskeletal mediated processes playing a major role in cellular activities such as cell division, morphogenesis, and functioning such as chloroplast positioning, pollen tube and root hair elongation and the movement of guard cells. Therefore, in the long run the screen described here has clear agricultural implications.

Full text
Abstract:
In road mitigation systems characterized by multiple wildlife crossing structures (CS) and multiple-focal species, these species-specific design criteria are important to meeting management goals. CS types and locations are fixed in place and cannot be manipulated experimentally; long term studies may offer the best chance to inform evidence-based designs for new CS projects in the future. Long-term data from Banff National Park are uniquely posed to answer these critical questions. More recently, highway mitigation along US93 in Montana provides an additional case study with which to understand the responses of large animals to different CS designs. The purpose of this study is to identify factors affecting movement of large mammals through CS using data sets from both mitigation projects. Year-round monitoring of CS use was used in an analytical framework to address questions regarding species-specific and community level use of CS; design and habitat factors that best explain species-specific variation; and whether importance of design parameters changes over time. Over the 17 years of the Banff study, and the six years of the Montana study, CS facilitated over 200,000 crossing events at 55 locations. There were significant changes in annual crossing events over time. Variables associated with CS passage rates were species specific, but aligned with a few clusters of preference. With the exception of coyotes, all large carnivore species preferred open span bridges or overpasses to other CS types. In Montana, fencing was positively associated with passage rates for black bears and cougars. We found that wider CS tend to be preferred by most species, irrespective of their location. We also found that wider CS tend to have shorter ‘adaptation’ curves than narrower ones for grizzly bears, coyotes, cougars, and moose. Depending on the heterogeneity of the landscape near the highway, more CS may not create more crossing opportunities if local habitat conditions do not favor animals’ access to the road. At the scale of ecological communities, the flows of mass and energy are likely enough to alter the distribution of ecological processes in the Banff and Montana ecosystems. Our results highlight the value of long-term monitoring for assessing the effectiveness of mitigation measures. Our work confirms the species-specific nature of measure CS performance, leading to our primary recommendation that a diversity of CS designs be considered an essential part of a well-designed mitigation system for the large mammals of western North America. Short-term monitoring efforts may fail to accurately portray the ecological benefits of mitigation for populations and ecological communities. Our results will help to inform design and aid in the establishment of robust, long-term performance measures.

Full text
Abstract:
This report describes activity conducted in several lines of research associated with field-scale water and solute processes. A major effort was put forth developing a stochastic continuum analysis for an important class of problems involving flow of reactive and non reactive chemicals under steady unsaturated flow. The field-scale velocity covariance tensor has been derived from local soil properties and their variability, producing a large-scale description of the medium that embodies all of the local variability in a statistical sense. Special cases of anisotropic medium properties not aligned along the flow direction of spatially variable solute sorption were analysed in detail, revealing a dependence of solute spreading on subtle features of the variability of the medium, such as cross-correlations between sorption and conductivity. A novel method was developed and tested for measuring hydraulic conductivity at the scale of observation through the interpretation of a solute transport outflow curve as a stochastic-convective process. This undertaking provided a host of new K(q) relationships for existing solute experiments and also laid the foundation for future work developing a self-consistent description of flow and transport under these conditions. Numerical codes were developed for calculating K(q) functions for a variety of solute pulse outflow shapes, including lognormal, Fickian, Mobile-Immobile water, and bimodal. Testing of this new approach against conventional methodology was mixed, and agreed most closely when the assumptions of the new method were met. We conclude that this procedure offers a valuable alternative to conventional methods of measuring K(q), particularly when the application of the method is at a scale (e.g. and agricultural field) that is large compared to the common scale at which conventional K(q) devices operate. The same problem was approached from a numerical perspective, by studying the feasibility of inverting a solute outflow signal to yield the hydraulic parameters of the medium that housed the experiment. We found that the inverse problem was solvable under certain conditions, depending on the amount of noise in the signal and the degree of heterogeneity in the medium. A realistic three dimensional model of transient water and solute movement in a heterogeneous medium that contains plant roots was developed and tested. The approach taken was to generate a single realization of this complex flow event, and examine the results to see whether features were present that might be overlooked in less sophisticated model efforts. One such feature revealed is transverse dispersion, which is a critically important component in the development of macrodispersion in the longitudinal direction. The lateral mixing that was observed greatly exceeded that predicted from simpler approaches, suggesting that at least part of the important physics of the mixing process is embedded in the complexity of three dimensional flow. Another important finding was the observation that variability can produce a pseudo-kinetic behavior for solute adsorption, even when the local models used are equilibrium.

Warrick, Arthur W., Gideon Oron, Mary M. Poulton, Rony Wallach, and Alex Furman. Multi-Dimensional Infiltration and Distribution of Water of Different Qualities and Solutes Related Through Artificial Neural Networks. United States Department of Agriculture, January 2009. http://dx.doi.org/10.32747/2009.7695865.bard.

Full text
Abstract:
The project exploits the use of Artificial Neural Networks (ANN) to describe infiltration, water, and solute distribution in the soil during irrigation. It provides a method of simulating water and solute movement in the subsurface which, in principle, is different and has some advantages over the more common approach of numerical modeling of flow and transport equations. The five objectives were (i) Numerically develop a database for the prediction of water and solute distribution for irrigation; (ii) Develop predictive models using ANN; (iii) Develop an experimental (laboratory) database of water distribution with time; within a transparent flow cell by high resolution CCD video camera; (iv) Conduct field studies to provide basic data for developing and testing the ANN; and (v) Investigate the inclusion of water quality [salinity and organic matter (OM)] in an ANN model used for predicting infiltration and subsurface water distribution. A major accomplishment was the successful use of Moment Analysis (MA) to characterize “plumes of water” applied by various types of irrigation (including drip and gravity sources). The general idea is to describe the subsurface water patterns statistically in terms of only a few (often 3) parameters which can then be predicted by the ANN. It was shown that ellipses (in two dimensions) or ellipsoids (in three dimensions) can be depicted about the center of the plume. Any fraction of water added can be related to a ‘‘probability’’ curve relating the size of the ellipse (or ellipsoid) that contains that amount of water. The initial test of an ANN to predict the moments (and hence the water plume) was with numerically generated data for infiltration from surface and subsurface drip line and point sources in three contrasting soils. The underlying dataset consisted of 1,684,500 vectors (5 soils×5 discharge rates×3 initial conditions×1,123 nodes×20 print times) where each vector had eleven elements consisting of initial water content, hydraulic properties of the soil, flow rate, time and space coordinates. The output is an estimate of subsurface water distribution for essentially any soil property, initial condition or flow rate from a drip source. Following the formal development of the ANN, we have prepared a “user-friendly” version in a spreadsheet environment (in “Excel”). The input data are selected from appropriate values and the output is instantaneous resulting in a picture of the resulting water plume. The MA has also proven valuable, on its own merit, in the description of the flow in soil under laboratory conditions for both wettable and repellant soils. This includes non-Darcian flow examples and redistribution and well as infiltration. Field experiments were conducted in different agricultural fields and various water qualities in Israel. The obtained results will be the basis for the further ANN models development. Regions of high repellence were identified primarily under the canopy of various orchard crops, including citrus and persimmons. Also, increasing OM in the applied water lead to greater repellency. Major scientific implications are that the ANN offers an alternative to conventional flow and transport modeling and that MA is a powerful technique for describing the subsurface water distributions for normal (wettable) and repellant soil. Implications of the field measurements point to the special role of OM in affecting wettability, both from the irrigation water and from soil accumulation below canopies. Implications for agriculture are that a modified approach for drip system design should be adopted for open area crops and orchards, and taking into account the OM components both in the soil and in the applied waters.
