TCAD approaches to multidimensional simulation of advanced semiconductor devices

description: Technology scaling increasingly emphasizes complexity and non-ideality
of the electrical behavior of semiconductor devices and boosts interest on alternatives to the conventional planar MOSFET architecture.
TCAD simulation tools are fundamental to the analysis and development of new technology generations. However, the increasing device
complexity is reflected in an augmented dimensionality of the problems
to be solved. The trade-off between accuracy and computational cost of
the simulation is especially influenced by domain discretization: mesh
generation is therefore one of the most critical steps and automatic approaches are sought. Moreover, the problem size is further increased by
process variations, calling for a statistical representation of the single
device through an ensemble of microscopically different instances. The
aim of this thesis is to present multi-disciplinary approaches to handle
this increasing problem dimensionality in a numerical simulation perspective. The topic of mesh generation is tackled by presenting a new
Wavelet-based Adaptive Method (WAM) for the automatic refinement
of 2D and 3D domain discretizations. Multiresolution techniques and
efficient signal processing algorithms are exploited to increase grid resolution in the domain regions where relevant physical phenomena take
place. Moreover, the grid is dynamically adapted to follow solution
changes produced by bias variations and quality criteria are imposed
on the produced meshes. The further dimensionality increase due to
variability in extremely scaled devices is considered with reference to
two increasingly critical phenomena, namely line-edge roughness (LER)
and random dopant fluctuations (RD). The impact of such phenomena
on FinFET devices, which represent a promising alternative to planar
CMOS technology, is estimated through 2D and 3D TCAD simulations
and statistical tools, taking into account matching performance of single
devices as well as basic circuit blocks such as SRAMs. Several process
options are compared, including resist- and spacer-defined fin patterning as well as different doping profile definitions. Combining statistical
simulations with experimental data, potentialities and shortcomings of
the FinFET architecture are analyzed and useful design guidelines are
provided, which boost feasibility of this technology for mainstream applications in sub-45 nm generation integrated circuits.

description: In two-dimensional loop models, the scaling properties of critical random curves are encoded in the correlators of connectivity operators. In the dense O(n) loop model, any such operator is naturally associated to a standard module of the periodic TemperleyLieb algebra. We introduce a new family of representations of this algebra, with connectivity states that have two marked points, and argue that they define the fusion of two standard modules. We obtain their decomposition on the standard modules for generic values of the parameters, which in turn yields the structure of the operator product expansion of connectivity operators.
Spatial and temporal variability and ecological processes in the epibenthic assemblages of the northern Adriatic Sea

description: Several coralligenous reefs occur in the soft bottoms of the northern Adriatic continental shelf. Mediterranean coralligenous habitats are characterised by high species diversity and are intrinsically valuable for their biological diversity and for the ecological processes they support. The conservation and management of these habitats require quantifying spatial and temporal variability of their benthic assemblages. This PhD thesis aims to give a relevant contribution to the knowledge of the structure and dynamics of the epibenthic assemblages on the coralligenous subtidal reefs occurring in the northern Adriatic Sea. 
The epibenthic assemblages showed a spatial variation larger compared to temporal changes, with a temporal persistence of reef-forming organisms. Assemblages spatial heterogeneity has been related to morphological features and geographical location of the reefs, together with variation in the hydrological conditions. 
Manipulative experiments help to understand the ecological processes structuring the benthic assemblages and maintaining their diversity. In this regards a short and long term experiment on colonization patterns of artificial substrata over a 3-year period has been performed in three reefs, corresponding to the three main types of assemblages detected in the previous study. The first colonisers, largely depending by the different larval supply, played a key role in determining the heterogeneity of the assemblages in the early stage of colonisation. Lateral invasion, from the surrounding assemblages, was the driver in structuring the mature assemblages. These complex colonisation dynamics explained the high heterogeneity of the assemblages dwelling on the northern Adriatic biogenic reefs.
The buildup of these coralligenous reefs mainly depends by the bioconstruction-erosion processes that has been analysed through a field experiment. Bioconstruction, largely due to serpulid polychaetes, prevailed on erosion processes and occurred at similar rates in all sites. Similarly, the total energy contents in the benthic communities do not differ among sites, despite being provided by different species. Therefore, we can hypothesise that both bioconstruction processes and energetic storage may be limited by the availability of resources. Finally the major contribution of the zoobenthos compared to the phytobenthos to the total energetic content of assemblages suggests that the energy flow in these benthic habitats is primarily supported by planktonic food web trough the filter feeding invertebrates.
Is the Nicolai map unique?

description: The Nicolai map is a field transformation that relates supersymmetric theories at finite couplings g with the free theory at g = 0. It is obtained via an ordered exponential of the coupling flow operator integrated from 0 to g. Allowing multiple couplings, we find that the map in general depends on the chosen integration contour in coupling space. This induces a large functional freedom in the construction of the Nicolai map, which cancels in all correlator computations. Under a certain condition on the coupling flow operator the ambiguity disappears, and the power-series expansion for the map collapses to a linear function in the coupling. A special role is played by topological (theta) couplings, which do not affect perturbative correlation functions but also alter the Nicolai map. We demonstate that for certain ‘magical’ theta values the uniqueness condition holds, providing an exact map polynomial in the fields and independent of the integration contour. This feature is related to critical points of the Nicolai map and the existence of ‘instantons’. As a toy model, we work with N = 1 supersymmetric quantum mechanics. For a cubic superpotential and a theta term, we explicitly compute the one-, two- and three-point correlation function to one-loop order employing a graphical representation of the (inverse) Nicolai map in terms of tree diagrams, confirming the cancellation of theta dependence. Comparison of Nicolai and conventional Feynman perturbation theory nontrivially yields complete agreement, but only after adding all (1PI and 1PR) contributions.

description: The acclaimed Maxwell-Bloch (or Arecchi-Bonifacio) equations are a valid dynamical model, effectively describing wave propagation in nonlinear optical media: from the amplification in input-output devices to multimode instabilities arising in laser systems. However, the inherent spatial variability of the physical observables represents an obstacle to fast simulations and analysis, especially whenever networks of active elements have to be considered. In this paper, we propose an approach which, stripping the spatial dependence of its role as a generator of dynamical richness, allows for a compelling simple portrait. It leads to (a few) ordinary differential equations in input-output configurations, complemented by a time-delayed feedback in closed-loop setups. Such scheme reproduces accurately the dynamics, paving the way to a plain treatment of the wealth of phenomena described by the Maxwell-Bloch equations.

title: Socioeconomic Status Influence on Mothers’ Interactions with Infants: Contributions to Early Infant Development
Creators: name: Gurko, Krista L.
Publisher: name: Utah State University
Year: 2018

description: Children from different socioeconomic backgrounds often have different long-term outcomes in terms of school, language, and emotional wellbeing. At this time, no reasons for these differences have been agreed upon by experts across disciplines. Parents with different personal characteristics and life situations use different types and amounts of interactions with their infants. The social interactions infants experience during their first year of life provide the start of their developmental path in the areas of language and executive control while also guiding their expectations for interactions with people around them.
This study used previously unpublished data from a sample of 79 young infants, age 3 to 9 months, and their mothers. There was a set of five research questions. The first question guided exploration of how socioeconomic status (SES; represented by maternal education and family income) was associated with the parenting behaviors mothers used with their infants. The second question guided exploration of how mothers’ psychosocial resources (represented by child development knowledge and parenting stress) were associated with the parenting behaviors mothers used with their infants. The third question addressed whether associations between maternal education and parenting behavior were directly connected or if the amount of child development knowledge influenced the association. The fourth question addressed whether associations between family income and parenting behavior were directly connected or if the amount of mothers’ parenting stress influenced the association. The final question addressed whether associations between mothers’ psychosocial parenting resources and infant development were directly connected or if the associations were instead connected by mothers’ psychosocial resources.
During a single home visit with each mother and her young infant, the research visitor assessed infant development, video recorded the mother and infant playing during a free play session, and asked mothers to fill out questionnaires. Project questionnaires addressed mothers’ education and family income as well as their levels of child development knowledge and parenting stress. None of the findings directly related to the five hypotheses were statistically significant. However, follow-up analyses provided information about potential future directions for investigating the links between SES, parenting interactions, and infant competencies using smaller categories of education and income levels. These findings from follow-up questions may guide potential future directions for identifying SES and psychosocial influences on early parenting interaction behaviors and young infants’ early development.

description: Perovskite-on-silicon tandem solar cells are a promising candidate to significantly increase the efficiency of PV modules. Despite the fast research progress on material and solar cells aspects, there is still a lack of processes for an industrial module integration of these devices. One aspect hereby is the adaption of encapsulation materials and processes to the requirements of perovskite materials. Process temperatures of about 150 °C are necessary to use well proven, in silicon PV commonly applied encapsulation materials with a high reliability. However, perovskites start to decompose into their components at high temperatures. This limits the encapsulation process temperature, which in turn constraints the choice of encapsulation materials. This work presents an encapsulation process for methylammonium lead iodide (MAPhb) single junction perovskite solar cells (PSCs) with conventional production tools in glass-glass modules that serves as a model system for perovskite tandem applications. We evaluate the influence of the encapsulation process temperature between 120 °C and 160 °C on the performance of mini modules. The UV-absorbing encapsulation material is processable over the whole investigated temperature regime. We observe a difference in the IV-characteristics between the PSCs encapsulated in the temperature range of 120 °C - 140 °C to those processed at 160 °C. At lower encapsulation temperatures the IV-curves taken 1 h after encapsulation show a pronounced S-shape and no degradation of Foe. In contrast, the PSCs encapsulated at 160 °C exhibit a Foe decrease of up to 29% compared to the initial measurement shortly after PSC fabrication and no significant S-shape. Both, the S-shape that occurs at low encapsulation temperatures and the Foe loss after encapsulation at 160 °C, are no longer significant after one week of module storage under dark conditions. The presented encapsulation process therefore does not permanently damage the MAPbb PSCs even at a standard encapsulation temperature of 160 °C. To ensure long-term operation, we test the fabricated mini modules in a damp heat test at 85 °C and a relative humidity of 85%. We find no significant additional degradation caused by damp heat in 1250 h test duration compared to a reference module stored in ambient air.
title: The Effects of Geometric and Stoichometric Change in Nanoparticles and Materials on Lattice Thermal Conductivity
Creators: name: Yorgason, W. Tanner
Publisher: name: Utah State University
Year: 2018

description: Thermal transport properties are critical for applications ranging from thermal management to energy conversion. Passive thermal management has been an area of study for over a century and has only grown as technology has advanced because it requires no additional energy to remove heat. Changing the nanostructure of the materials involved in passive heat transfer methods, either by geometric changes or stoichiometric changes, can greatly improve the effectiveness of this heat transfer method. In order to explore this further, this work employs LAMMPS molecular dynamics (MD) simulation software to calculate the lattice thermal conductivity (λp) of a nanoparticle (NP) and material used indifferent passive heat transfer methods after either modifying their geometry or stoichiometry. The NPs this work will simulate are single-wall carbon nanotubes (SWCNTs), which have been well known for high λp, and their applications in improving thermal conductivity in matrix materials. The material this work will simulate is magnesium silicide (Mg2Si), a thermoelectric material. Thermoelectric materials, in general, become more efficient in converting heat into electrical power as their λp decreases. λp will be calculated for SWC-NTs of varying lengths, diameters, and at varying equilibration temperatures (Teq). λp will be calculated for samples of pure Mg2Si and Mg2Si with off-stoichiometry over a range of Teq values. Two methods will be used to induce the off-stoichiometry: atomic silicon (Si) substitutionals, and Si NPs. A range of stoichiometric ratios will be applied to the material by both methods, and then λp will be calculated for each of these cases. This is done so as to observe which method of stoichiometric change, given the same stoichiometric ratio, decreases λp greater, and, therefore, causes Mg2Si to be a better thermoelectric material. It is expected that increases in length will increase the λp of the SWCNT, while increases in diameter and Teq will decrease λp. It is expected that increases in atomic percent (a/o) Si and Teq will decrease λp regardless of the method of stoichiometric change, and that the Si NP method will decrease λp more than the atomic Si substitutional method.

description: Studies of heavy-ion collisions at the LHC will benefit from an array of qualitatively new probes not readily available at lower collision energies. These include fully formed jets at ET > 50 GeV, Z0's and abundantly produced heavy flavors. For Pb+Pb running at LHC design luminosity, the collision rate in the CMS interaction region will exceed the available bandwidth to store data by several orders of magnitude. Therefore an efficient trigger strategy is needed to select the few percent of the incoming events containing the most interesting signatures. In this report, we will present the heavy-ion trigger strategy developed for the unique two-layer trigger system of the CMS experiment which consists of a ``Level-1'' trigger based on custom electronics and a High Level Trigger (HLT) implemented using a large cluster of commodity computers.

description: In this thesis we describe in detail the Monte Carlo simulation (LVDG4) built
to interpret the experimental data collected by LVD
and to measure the muon-induced neutron yield in iron 
and liquid scintillator.
A full Monte Carlo simulation, based on the Geant4 (v 9.3) toolkit, has been 
developed and validation tests have been performed.

We used the LVDG4 to determine the active vetoing and the 
shielding power of LVD. The idea was to evaluate the feasibility to
host a dark matter detector in the most internal part, called
Core Facility (LVD-CF). The first
conclusion is that LVD is a good moderator, but the iron supporting structure
produce a great number of neutrons near the core. The second conclusions 
is that if LVD is used as an active veto for muons, the neutron flux 
in the LVD-CF is 
reduced by a factor 50, of the same order of magnitude of the neutron flux
in the deepest laboratory of the world, Sudbury.

Finally, the muon-induced neutron yield has been measured.
In liquid 
scintillator we found $(3.2 \pm 0.2) \times 10^{-4}$ 
n/g/cm$^2$, in agreement with previous measurements performed at different
depths and with the general trend predicted by theoretical calculations
and Monte Carlo simulations.  

Moreover we present the first measurement, in our knowledge,
of the neutron yield in iron:
$(1.9 \pm 0.1) \times 10^{-3}$ n/g/cm$^2$. That measurement provides an
important check for the MC of neutron production in heavy materials that are 
often used as shield in low background experiments.

description: Abstract

Anthropometric factors affect the stability limits of the individual and can affect the motor strategies relating to balance control. The objective of this study was to take normative measurement of dynamic gait index and 5 times sit to stand test among elderly population and to compare the preliminary values of above mentioned tests with age. Data was collected from the elderly population from old age homes of Lahore and community dwelling population who meet the inclusion criteria between the age group 45-60 divided into 3 groups (G1: 45-50, G2:50-55, G3:55-60). Data was collected through the performance of dynamic gait index and 5 time sit to stand test were performed. There was a significant positive correlation between BMI and 5STS score as R=0.94 and p<0.05. The highest and lowest effect of BM1 on 5 time sit to stand test score were found in the age groups of 45-50, 51-55 and 56-60. A negative relationship between DGI and BMI was found. Another strong correlation of -0.320 was observed between age and total DGI score. This study concluded that mean 5STS score was found to be 16.71seconds. The effects of BMI on 5 time sit to stand test performance increased with increasing age. Average dynamic gait index score was 16.10.

description: Stars in globular clusters formed and evolved in the most extreme environment: high density and low metallicity. If the formation of stars and planets are at all sensitive to environmental conditions, this should therefore be evident in globular clusters. Observations have indicated that hot Jupiters are at least an order of magnitude less prevalent in the central region of the globular cluster 47 Tucanae than in the field. In this work, we explore the claims in the literature for additional consequences for the low mass stellar initial mass function. Tidal capture, the mechanism that produces X-ray binaries in globular clusters, applies also to brown dwarfs (BDs). This process produces tight stellar-BD binaries that would be detectable by transit surveys. Applying a Monte Carlo dynamical evolution model, we compute the overall BD capture rates. We find that the number of captures is lower than previous estimates. Capture efficiency increases steeply with stellar mass, which means that mass segregation reduces capture efficiency as BDs and low mass stars occupy the same regions. The result of this effect is that the current constraints on the short period companion fraction remains marginally consistent with initially equal numbers of BDs and stars. However, our findings suggest that expanding the sample in 47 Tuc or surveying other globular clusters for close sub-stellar companions can yield constraints on the sub-stellar initial mass function in these environments. We estimate the capture rates in other globular clusters and suggest that 47 Tuc remains a promising target for future transit surveys.

description: We propose a hybrid anharmonic-harmonic scheme for vibrational broadenings, which embeds a reduced-space vibrational configuration interaction (VCI) anharmonic wave function treatment in the independent-mode displaced harmonic oscillator (IMDHO) model. The resulting systematically-improvable VCI-in-IMDHO model allows including the vibronic effects of all vibrational degrees of freedom, while focusing the effort on the important degrees of freedom with minimal extra computational effort compared to a reduced-space VCI treatment. We show for oligothiophene examples that the VCI-in-IMDHO approach can yield accurate vibrational profiles employing smaller vibrational spaces in the VCI part than the reduced-space VCI approach. By this, the VCI-in-IMDHO model enables accurate calculation of vibrational profiles of common fluorescent dyes with more than 100 vibrational degrees of freedom. We illustrate this for three examples of fluorescent biomarkers of current interest. These are the oligothiophene-based fluorescent dye called HS84, 1,4-diphenylbutadiene, and an anthracene diimide. For all examples, we assess the impact of the anharmonic treatment on the vibrational broadening, which we find to be more pronounced for the intensities than for the peak positions.
title: Silage Corn Hybrid Response to Row Width and Plant Density in the Intermountain West
Creators: name: Pieper, Mark A.
Publisher: name: Utah State University
Year: 2018

description: Corn (Zea mays L.) hectarage has increased rapidly in Utah and Idaho in recent years due to expansion of the dairy industry, but little is known about corn production practices that optimize yield and quality of silage corn in semi-arid irrigated cropping systems. The objective of this study was to determine the dry matter yield and quality effects of corn hybrids grown in different plant densities and row widths in the Intermountain West. Field experiments were conducted under irrigation in 2015 and 2016 at locations near North Logan, Utah and Jerome, Idaho. The experimental design was a randomized complete block in a split-split plot arrangement with four replications. The whole plot treatment was hybrid (DKC 49-29, DKC 56-54, and DKC 61-88), the sub-plot treatment was row width (76 and 51-cm), and the sub-sub plot treatment was plant density (61,776 to 123,552 plants ha-1 at intervals of 12,355 plants ha-1). The 51-cm row width resulted in forage dry matter yield increases of 4-7% over corn in 76-cm rows. Hybrids differed in response to row width, with no difference detected for the 99-RM hybrid but a significant yield increase for the 106- and 111-RM hybrids by planting in narrow rows. Yield increased quadratically as plant population increased from 61,776 to 123,552 plants ha-1 for all hybrids. The only forage nutritive value that was influenced by row spacing was crude protein (CP), where the 76-cm row spacing showed a 4.5% advantage over the 51-cm row width. Starch increased approximately 3% from the lowest to highest plant densities tested. Net returns showed possible positive increases when comparing row width adjustments. Silage corn yield and quality in the Intermountain West appears to be optimized in 51-cm rows at a plant population between 86,487 and 98,842 plants ha-1.

description: Abstract

The purpose of this study is to examine the role of culture and religiosity in the occurrence of budgetary slack in planning and implementing budgets in Regional Governments in Indonesia. This study uses a qualitative descriptive method with an explanatory approach, namely explaining the phenomena that occur related to the practice of budgetary slack in local governments. The data used is primary data, through observations and interviews with parties involved in budget planning and implementation. The secondary data used in this study is in the form of the Regional Revenue and Expenditure Budget and the Budget Realization Report for 2020 to 2022. The results of the study show that the cultural aspect plays an important role in the occurrence of budgetary slack, while religiosity does not play much role in the occurrence of budgetary Slack. This research is expected to have implications in improving the budgeting system, so that local governments can develop a more accurate and realistic budgeting system. In addition, local governments are also expected to increase transparency and accountability in the budgeting process.

Il volume raccoglie un ampio repertorio di brani musicali appartenenti a generi destinati ai periodi liturgici della Quaresima e del Triduo pasquale. Il lavoro è dedicato ai responsori considerati innanzitutto come progetto compositivo a sé stante e come fonte di rilievo nell’ambito della musica sacra e del genere responsoriale in particolare. Lo studio è suddiviso in due parti: la prima riguarda le ricerche codicologiche sul volume, del quale si riassume anche la storia con nuove ricerche sulla sua acquisizione da parte dell’Accademia Filarmonica. Viene poi esaminato il contesto storico-liturgico della musica per la Settimana Santa e si prendono in esame gli aspetti stilistici del repertorio responsoriale polifonico italiano dalla metà del  ‘500 allla prima metà del ’700, in particolare nell’ambito del cosiddetto «stile osservato» del tempo. Nel terzo ed ultimo capitolo della prima parte vengono analizzati nella forma e nello stile i responsori del Ms 443 di Bologna, tenendo conto della teoria musicale e delle consuetudini contrappuntistiche in vigore tra la fine del sec. XVII e l’inizio del sec. XVIII. Nelle rispettive appendici ai capitoli si dànno le Tavole esplicative, con dati di natura codicologica, tecnico-musicale e testuale liturgica e gli elenchi dettagliati delle fonti responsoriali polifoniche rintracciate, manoscritte e a stampa. La seconda parte del lavoro presenta l’edizione critica della musica, con annessa la sua riproduzione in facsimile su CD. Nell’apparato critico la sezione dei Testi restituisce l’edizione filologica dei testi liturgici intonati.

description: We analyze the coupling of two flux qubits with a general many-body projector into the low-energy subspace. Specifically, we extract the effective Hamiltonians that controls the dynamics of two qubits when they are coupled via a capacitor and/or via a Josephson junction. While the capacitor induces a static charge coupling tunable by design, the Josephson junction produces a magnetic-like interaction easily tunable by replacing the junction with a SQUID. Those two elements allow to engineer qubits Hamiltonians with $XX$, $YY$ and $ZZ$ interactions, including ultra-strongly coupled ones. We present an exhaustive numerical study for two three-Josephson junctions flux qubit that can be directly used in experimental work. The method developed here, namely the numerical tool to extract qubit effective Hamiltonians at strong coupling, can be applied to replicate our analysis for general systems of many qubits and any type of coupling.

description: The negative CAPM alphas of high-beta and high-variance stocks are attributable to an unaccounted factor in the CAPM. We use eight seemingly unrelated anomalies to construct a composite factor in the spirit of the optimal orthogonal portfolio (FOP). Accounting for FOP re-establishes a positive relation between beta and average returns in time series regressions as well as cross-sectional and explains the negative alphas of high-beta and high-variance stocks. To analyze economic drivers behind FOP, we perform a horse race between leverage constraints, investor sentiment, and disagreement. Our results highlight investor sentiment as the most promising explanation for the low-risk effect.

There is a need for proven methods of inter-seeding legumes into existing cool-season grass pastures as well as knowledge of how animals prefer legumes to grasses and how the nutritive value of forages change throughout the growing season. This research provides a resource for effective integration of legumes into pastures of the Intermountain West. Alfalfa, birdsfoot trefoil, and cicer milkvetch were inter-seeded into existing cool-season grass pastures following pretreatments of light tillage, mowing and glyphosate. Early spring and fall inter-seeding was unsuccessful, while late spring was moderately successful with overall alfalfa frequency of 30% after a year. Summer inter-seeding was the most successful with birdsfoot trefoil, alfalfa, and cicer milkvetch frequency of 42, 32, and 22%, respectively. In the animal preference study, when compared to tall fescue, birdsfoot trefoil was always utilized more.In most observations birdsfoot trefoil utilization was higher than orchard grass. While in all comparisons with meadow bromegrass there was no difference in utilization. During early growth, perennial ryegrass utilization was higher than birdsfoot trefoil utilization, but no difference in utilization was detected in later observations. Overall, birdsfoot trefoil was utilized 73% overall while grass utilization was 74, 67, 64, and 53% for perennial ryegrass, meadow bromegrass, orchardgrass and tall fescue, respectively. The interaction of growth stage and time of season on the nutritive value of alfalfa, birdsfoot trefoil, cicer milkvetch, orchardgrass, perennial ryegrass and tall fescue was determined. In the spring to early summer, legume nutritive value decreased rapidly with maturity, in midsummer the nutritive value decreased slowly with maturity, while in late summer the nutritive value remained stable. In the spring, grass nutritive value decreased rapidly, while in mid to late summer all grass regrowth was vegetative and the nutritive value remained stable. By inter-seeding in the summer, effectively managing mixed pastures, and utilizing forage at its highest nutritive value, legumes can benefit the pastures of the Intermountain West.

description: A new dinoflagellate cyst genus and species are described here as Hiddenocysta gen. nov. and Hiddenocysta matsuokae sp. nov. from Holocene sediments in a core from the west coast of Vancouver Island (British Columbia, Canada). The genus Hiddenocysta encompasses spherical to ovoid skolochorate cysts, characterized by a gonyaulacoid plate pattern and a 2P precingular archeopyle. The species H. matsuokae is characterized by a granular wall and slender trifurcate processes with heavily perforated process bases. Two end members are described here based on process morphology and number of processes (Forma 1 and 2). Cyst wall chemistry is analyzed using micro-Fourier transform infrared (FTIR) spectroscopy and reveals a unique dinosporin composition consistent with a gonyaulacoid autotrophic feeding strategy.

description: Properties and different representations of the Uehling potential are investigated. Based on these properties and by using our formulas for the Fourier transform of the Uehling potential we have developed the new analytical, logically closed and physically transparent procedure which can be used to evaluate the lowest-order vacuum polarization correction to the cross sections of a number of QED processes, including the Mott electron scattering, bremsstrahlung, creation and/or annihilation of the $(e^{-}, e^{+})-$pair in the field of a heavy Coulomb center, e.g., atomic nucleus.
title: Using Social Network Analysis to Examine the Intersection of Adolescent Friendships and Health Behavior

description: Adolescence marks a vulnerable developmental period for health behavior, and research demonstrates that social context and interpersonal relationships impact the health behavior choices of adolescents. In addition, theories of adolescent development suggest a bidirectional relationship between environmental factors, including social relationships, and health. Friendships are one of the most salient relationships during adolescence, and new methods from the field of social network analysis allow researchers to explicitly examine the mechanisms through which friends influence health behavior, and simultaneously, how health and health behavior impacts the formation of friendships. Importantly, social network methods (e.g., stochastic actor-based models, exponential random graph models) overcome statistical limitations of alternative methodology. For example, methods from social network analysis incorporate interdependencies between individuals in a social network (e.g., adolescents within a school) into the statistical modeling framework, and are capable of simultaneously estimating social and behavioral outcomes.
Through a sequence of three distinct studies, this project applies rigorous methods from social network analysis to investigate: (1) the differential impact of adolescent friendships on health-risk (e.g., alcohol use) and health-protective (e.g., physical activity) behaviors; (2) the role of perceived social acceptability and peer influence in shaping adolescent cigarette use; and (3) the social consequences, including social withdrawal and social marginalization, of adolescents with chronic illness.

description: Abstract

Understanding the optimal planting time and cultivar selection can significantly enhance cotton production efficiency and sustainability. Such insights are crucial for farmers and agricultural planners to make informed decisions that maximize productivity and economic returns. This study aimed to investigate the effects of different planting dates on the phenological development, growth, and seed cotton yield of two cotton cultivars (FH-142 and CIM-616), as well as to simulate these effects using modeling for better crop management. A study conducted at the Central Cotton Research Institute in Multan, Pakistan, the field experiment utilized a randomized complete block design with split-plot arrangement and three replications. The planting dates were April 1, April 15, and May 1. Results showed that CIM-616 superior performance with the maximum leaf area index (LAI) (4.45), leaf area duration (LAD) (444.55 days), total dry matter (TDM) (1540 g m-2), crop growth rate (CGR) (9.88 g m-2 d-1), and net assimilation rate (NAR) (3.35 g m-2 d-1) when planted on April 1, followed by April 15, and the least on May 1. Phenological observations revealed that CIM-616 planted on April 1 took the longest duration to reach various growth stages and had the highest plant height (134.33 cm), number of bolls (47), sympodial branches (57), and seed cotton yield (3467.33 kg ha-1). Additionally, the CROPGRO-Cotton model was calibrated and evaluated using the field data. The model's predictions for phenology, LAI, and yield closely matched the observed values, with RMSE values indicating good agreement (e.g., RMSE for days to anthesis was 4.47 for FH-142 and 5.83 for CIM-616). The calibrated model accurately simulated the days to anthesis, maturity, and yield at different planting dates, demonstrating its applicability in predicting cotton growth and yield under varying climatic conditions. The study concluded that early planting (April 1) combined with the CIM-616 cultivar resulted in optimal growth and highest yield, emphasizing the importance of planting time and cultivar selection for maximizing cotton yield in the given agro-ecological conditions. The CROPGRO-Cotton model proved to be a valuable tool for simulating and optimizing cotton production.

description: We consider a model where electroweak symmetry breaking is driven by Technicolor dynamics with minimal particle content required for walking coupling and saturation of global anomalies. Furthermore, the model features three additional Weyl fermions singlet under Technicolor interactions, which provide for a one-loop unification of the Standard Model gauge couplings. Among these extra matter fields exists a possible candidate for weakly interacting dark matter. We evaluate the relic densities and find that they are sufficient to explain the cosmological observations and avoid the experimental limits from earth-based searches. Hence, we establish a non-supersymmetric framework where hierarchy and naturality problems are solved, coupling constant unification is achieved and a plausible dark matter candidate exists.
title: "Full On Toy Story": Exploring the Belief in Object Sentience in Western Culture

description: This thesis considers, from a folklorist’s perspective, the people in Western society who believe that everyday objects have feelings. It establishes these people as a cohesive group for study, referred to as “people to experience the belief in object sentience,” then analyzes their personal accounts of the experience to find both commonalities and differences. From this analysis and discussion of folkloristic perspectives on belief, the main argument is established: people in this group have generally been marginalized and could benefit from a more careful consideration of their beliefs.
