description: gem-Dihalocyclopropanes (1) are an important class of compound that play significant roles in contemporary organic synthesis. This is largely due to their ease of preparation, (which is normally accomplished via addition of the relevant dihalocarbene to an alkene), and the wide range of reactions they can undergo. These reactions can be divided into two broad subgroups, those that proceed with retention of the three membered ring, and those where one of the C-C bonds is broken, thus leading to ring cleavage. The vast majority of gem-dihalocyclopropanes described in the literature are the dibromo- or dichloro- systems, as these are the most synthetically accessible (1, where X = Br or Cl). Chapter One of this thesis provides an introduction to the preparation and synthetic utility of gem-dihalocyclopropanes, while the work described in the remainder of this thesis utilises such systems in work directed toward the synthesis of a number of alkaloidal ring-systems. Chapter Two of this thesis outlines work undertaken in the pursuit of a synthesis of pcrhydrohistrionicotoxin (50), a derivative of the alkaloid histrionicotoxin. A silver(l)-promoted cyclopropane ring-opening/spirocyclisation reaction was to be used as the key step in this work. Thus, starting from cyclopentanone, a pair of diastereoisomeric substrates, 124 and 125, has been prepared that contain all the functionality thought necessary for generating a substrate capable of engaging in the key reaction. Chapter Three outlines work undertaken in the pursuit of a synthesis of the core cis-3a-arylhydroindole structure of a number of Amaryllidaceae alkaloids. Starting with gem-dibromoeyclopropane 146, iodide 163 was prepared over' 7 steps, and upon subjection of the latter compound to reductive radical cyclisation conditions resulted in the production of the cis-3a-arylhydroindole 164. Chapter Four outlines the preparation of a senes of N-protected and propargylated l-amino-2-aryl-2-cyclohexenes (213), from gem-dibromocyclopropanes such as 212. Several of these have been showu to undergo an intramolecular Alder-ene (IMAE) reaction in the presence of palladium acetate and the ligand BBEDA to afford C3aarylhexahydroindoles of the general form 214. Certain of these products may serve as precursors to the alkaloid tazettine (133). Chapter Five contains the experimental procedures and data to support all work outlined in this thesis.
A Minimum Column Density of 1 g cm^-2 for Massive Star Formation

description: Massive stars are very rare, but their extreme luminosities make them both the only type of young star we can observe in distant galaxies and the dominant energy sources in the universe today. They form rarely because efficient radiative cooling keeps most star-forming gas clouds close to isothermal as they collapse, and this favors fragmentation into stars ~ 1 g cm^-2 can avoid fragmentation and form massive stars. This threshold, and the environmental variation of the stellar initial mass function (IMF) that it implies, naturally explain the characteristic column densities of massive star clusters and the difference between the radial profiles of Halpha and UV emission in galactic disks. The existence of a threshold also implies that there should be detectable variations in the IMF with environment within the Galaxy and in the characteristic column densities of massive star clusters between galaxies, and that star formation rates in some galactic environments may have been systematically underestimated.

Chiral forms and three-flavor operators for staggered baryons

Year: 2006
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: In staggered QCD, many staggered baryons correspond to each physical state. Taste violations lift the continuum degeneracies of the baryons and introduce nonzero off-diagonal elements in the mass matrix. While presenting no problem of principle, these splittings and mixings complicate analyses of simulation results. However, in special cases operators with good SU(3) quantum numbers can be used to circumvent the splittings and mixings. I review what has been learned from staggered chiral perturbation theory, outline a program of attack for the amenable cases, and summarize the present status of work on the staggered chiral forms and operators with good SU(3)xGTS quantum numbers.

description: P.B. Chakraborty {\it et al.}, Phys. Rev. B {\bf 70}, 144411 (2004)) study of the LiHoF$_4$ Ising magnetic material in an external transverse magnetic field $B_x$ show a discrepancy with the experimental results, even for small $B_x$ where quantum fluctuations are small. This discrepancy persists asymptotically close to the classical ferromagnet to paramagnet phase transition. In this paper, we numerically reinvestigate the temperature $T$, versus transverse field phase diagram of LiHoF$_4$ in the regime of weak $B_x$. In this regime, starting from an effective low-energy spin-1/2 description of LiHoF$_4$, we apply a cumulant expansion to derive an effective temperature-dependent classical Hamiltonian that incorporates perturbatively the small quantum fluctuations in the vicinity of the classical phase transition at $B_x=0$. Via this effective classical Hamiltonian, we study the $B_x-T$ phase diagram via classical Monte Carlo simulations. In particular, we investigate the influence on the phase diagram of various effects that may be at the source of the discrepancy between the previous QMC results and the experimental ones. For example, we consider two different ways of handling the long-range dipole-dipole interactions and explore how the $B_x-T$ phase diagram is modified when using different microscopic crystal field Hamiltonians. The main conclusion of our work is that we fully reproduce the previous QMC results at small $B_x$. Unfortunately, none of the modifications to the microscopic Hamiltonian that we explore are able to provide a $B_x-T$ phase diagram compatible with the experiments in the small semi-classical $B_x$ regime.

description: Conversational Artificial Intelligence (AI) systems have recently sky-rocketed in popularity and are now used in many applications, from car assistants to customer support. The development of conversational AI systems is supported by a large variety of software platforms, all with similar goals, but different focus points and functionalities. A systematic foundation for classifying conversational AI platforms is currently lacking. We propose a framework for assessing the maturity level of conversational AI development platforms. Our framework is based on a systematic literature review, in which we extracted common and distinguishing features of various open-source and commercial (or in-house) platforms. Inspired by language reference frameworks, we identify different maturity levels that a conversational AI development platform may exhibit in understanding and responding to user inputs. Our framework can guide organizations in selecting a conversational AI development platform according to their needs, as well as helping researchers and platform developers improving the maturity of their platforms.

description: This report includes an analysis of traffic accident data in Kentucky for the years of 1993 through 1997. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical numbers and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.  The other primary objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city accident statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include alcohol involvement, occupant protection, speed, teenage drivers, pedestrians, bicycles, motorcycles, trucks, and vehicle defects. Other areas included in the analysis for which specific recommendations were not made include drug involvement, school bus accidents, and train accidents.

description: Climate change is affecting and will increasingly affect astronomical observations. In this paper, we investigated the role some key weather parameters play in the quality of astronomical observations, and analysed their long-term trends (longer than 30 years) in order to grasp the impact of climate change on current and future observations. In this preliminary study, we specifically analysed four parameters, the temperature, the surface layer turbulence, the wind speed at the jetstream layer and the humidity. The analyses is conducted with data from the Very Large Telescope (VLT), operated by the European Southern Observatory (ESO), located at Cerro Paranal in the Atacama desert, Chile, which is one of the driest places on Earth. To complete the data from the various sensors installed at Paranal, we used the fifth generation and 20th century European Centre Medium-Range Weather Forecasts (ECMWF) atmospheric reanalysis of the global climate, ERA5 (from 1980 to now) and ERA20C (from 1900 to 2010), which we interpolated at the Paranal observatory location. In addition, we also explored climate projections in this region, using the Coupled Model Intercomparison Project Phase 6 (CMIP6) multi-model ensemble, under the worst-case climate change Shared Socio-Economic Pathways (SSP5-8.5) scenario. Further investigation is needed to better understand the underlying mechanisms of change, as well as to assess the severity of the impact.

Assessment of multiple facets of social connection among autistic and non-autistic adults: development of the Connections with others scale (CWOS)
Creators: name: Mournet, Annabelle M.
Publisher: name: No Publisher Supplied
Year: 2023

description: Limited measures exist to assess levels of motivation, desire, and value associated with connecting with others among adults. Moreover, few social connection scales were developed with a goal of including autistic individuals to create a measure that has utility across neurodiverse populations. This study aims to develop a measure to assess different facets of social connection that is valid among both autistic and non-autistic adults. The sample consisted of 200 participants recruited online (autistic sample M age=35.9 (SD=12.6); non-autistic sample M age=41.7 (SD=18.8). Half of the sample self-reported a diagnosis of autism. Participants completed an initial set of 35 items to assess desire, value, enjoyment, and motivation to connect with others and provided feedback on these items. Exploratory factor analyses (EFA) were conducted separately with 50 autistic participants and 50 non-autistic participants. Criteria for item reduction in the measure included removal of items assigned to different factors across the two EFA models and factor loadings of less than .40. A single confirmatory factor analysis (CFA) using the remaining 100 participants was performed. Measurement invariance was examined between the autistic and non-autistic groups. Independent sample t-tests (autistic vs. non-autistic) and two-way ANOVAs (autism X gender) were conducted to examine outcomes of the newly developed scale. Two-factor models were produced by the EFAs. Item reduction approaches resulted in the retainment of 25 items in the Connections With Others Scale (CWOS). Scalar invariance was achieved. Autistic participants had significantly greater motivation/desire to connect with others compared to non-autistic participants (t(195)=3.49; p<.001). This model had a comparative fit index of 0.664, a standardized root mean square residual of 0.118 and a root mean square error of approximation of 0.190 (90%CI=0.179-0.201). The CWOS was developed to ensure utility among both non-autistic and autistic individuals alike. Poor fit metrics suggest the need for future testing of different combinations of items from the CWOS to improve fit. A measure such as the CWOS has the potential to allow for greater ability to assess numerous facets of social connection resulting in improved ability to produce research that clarifies theories and describes psychological phenomenon.

Has been said that depends on the individual needs of international security. Currently, test the legality of use of violence is primarily the Charter of the United Nations (Article 2 paragraph 1 and 4, Article 51). Any request for use of force is envisaged as to the legality of the SecurityCouncil.

description: The Harish-Chandra correlation functions, i.e. integrals over compact groups of invariant monomials prod tr{X^{p_1} Omega Y^{q_1} Omega^dagger X^{p_2} ... with the weight exp tr{X Omega Y Omega^dagger} are computed for the orthogonal and symplectic groups. We proceed in two steps. First, the integral over the compact group is recast into a Gaussian integral over strictly upper triangular complex matrices (with some additional symmetries), supplemented by a summation over the Weyl group. This result follows from the study of loop equations in an associated two-matrix integral and may be viewed as the adequate version of Duistermaat-Heckman's theorem for our correlation function integrals. Secondly, the Gaussian integration over triangular matrices is carried out and leads to compact determinantal expressions.

description: The Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189), undertaken by the Kentucky Transportation Center (KTC) on behalf of the Kentucky Transportation Cabinet (KYTC), has two main objectives. These objectives include 1) the evaluation of access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for one cluster of facilities located in Bath County in the Gateway Area Development District (ADD) and KYTC Highway District #9. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task are on-going and are documented elsewhere.  The sites to be evaluated were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the National Highway System, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used.  The site was visited several times for data collection and video recordings as listed in Appendix A. The following facilities are located in the area: Donotech, Custom Foods, and Bath Manufacturing. All facilities are located off of Kendall Springs Road, on Donotech Drive, Darnell Drive, and Bath Mfg. Drive. Figures 2 and 3 show the relative location of the facilities found at this site (note that Bath Manufacturing was not yet completed). Phone surveys completed on the facilities indicate that only moderate truck traffic from these facilities travel on Kendall Springs Road. Approximately 15 trucks per day are placed on the route due to the operations of this site.

description: Neural systems process information in a dynamical regime between silence and chaotic dynamics. This has lead to the criticality hypothesis which suggests that neural systems reach such a state by self-organizing towards the critical point of a dynamical phase transition. Here, we study a minimal neural network model that exhibits self-organized criticality in the presence of stochastic noise using a rewiring rule which only utilizes local information. For network evolution, incoming links are added to a node or deleted, depending on the node's average activity. Based on this rewiring-rule only, the network evolves towards a critcal state, showing typical power-law distributed avalanche statistics. The observed exponents are in accord with criticality as predicted by dynamical scaling theory, as well as with the observed exponents of neural avalanches. The critical state of the model is reached autonomously without need for parameter tuning, is independent of initial conditions, is robust under stochastic noise, and independent of details of the implementation as different variants of the model indicate. We argue that this supports the hypothesis that real neural systems may utilize similar mechanisms to self-organize towards criticality especially during early developmental stages.

Using results for the action of $OSp(2S+2|2S)$ and $B_L(2)$ on the corresponding spin chain, as well as mini-superspace and small $g_σ^2$ calculations, we conjecture the full spectrum and set of degeneracies on the entire critical line. Potential relationship with the $OSp(2S+2|2S)$ Gross-Neveu model is also discussed.

description: Contemporary archaeological research has put into practice different ways of approaching Neolithic pottery, such as the study of style, technology and use, or the study of pottery production, transportation and consumption. Additionally, the study of pottery in association with food is of great importance. Pottery is used in a variety of food practices, such as storage, preparation and consumption. The study of painted pottery from Neolithic Achilleion and Otzaki Magoula settlements in Thessaly is trying to approach the relation between painted pottery and food practices. Pottery distribution within the settlements and site organization are discussed in order to interpret the use of painted pottery and the kind of social practices that took place in Achilleion and Otzaki Magoula settlements.

description: The latest measurement of the K_S to gamma gamma branching ratio clearly shows an enhancement over the current theoretical prediction. As in other K and B meson decays, this invites to consider the possibility of the contribution of new physics. We study a particular form of the latter, which may be referred to as manifest mirror symmetry. The experimental data are described using previously determined values for the mixing angles of the admixtures of mirror matter in ordinary hadrons and by assuming that for pi^0, eta, eta', the mirror decay amplitudes have the same magnitudes as their ordinary counterparts.
The facilitation of spiritual connection for the First Nations’ people of British Columbia: a critical incident analysis
Creators: name: Christopher, Ada
Publisher: name: University of British Columbia
Year: 2009

description: Limited research has been conducted into First Nations' healing, particularly in the area of First Nations' spiritual connection. First Nations' spiritual connection is perceived to be important from a counselling perspective. The intent of this study was to construct a fairly comprehensive guide of what helps and what hinders spiritual connection among members of British Columbia's (BC's) First Nations, through a First Nations' voice. Eleven adult members of First Nations living in BC were interviewed to obtain information in the form of critical incidents regarding what helps or what hinders spiritual connection. From these interviews, 29 categories were described as what helped or hindered spiritual connection. These are: ceremonial activities, Elder's teachings/guidance, establishing a connection with nature, prayer, family connection, changing thinking, spiritual beliefs, supernatural experiences, residential school, helping others, seeking help, dreams, role model, spiritual practices, self awareness/self acceptance, receiving your name, cultural preservation/ reclamation, sacred object, First Nations' traditional beliefs, alcoholism and drug recovery, visions, establishing social connection, creative activity, philosophy of life, joining organized religion, teachings/guidance, cultural connection/cultural awareness, relationship to the Creator, speaking a traditional First Nations' language. The findings of this study contribute to the field of counselling psychology by providing a reasonably comprehensive scheme of categories and themes that describe, from a First Nations' perspective what facilitates spiritual connection.

Hexapanopeus caribbaeus.— Rathbun 1930, 399, pl. 171, figs. 3–5.— Coelho & Ramos 1972: 191.— Mantelatto et al. 2020: 73.
Material examined. 1 male (CW 6.55 × CL 5.56 mm), 2 females (CW 5.08 × CL 4.87 mm; CW 6.27 × 4.84 CL mm), station PA03, 16.vii.2021 (CCDB 7462).
Geographic distribution. Western Atlantic— USA (Florida), Antilles, north of South America, and Brazil (Pará, Piauí, Paraíba, Pernambuco, Alagoas, Bahia, Espírito Santo; São Paulo, Paraná, Santa Catarina, Rio Grande do Sul) (Coelho & Ramos 1972; Abele & Kim 1986; Rieger et al. 1996; Coelho Filho 2006; Almeida et al. 2007b; Coelho et al. 2008; Felder et al. 2009; Vieira & Calazans 2010; Nobrega & Martinelli-Lemos 2016; Mantelatto et al. 2020 as Hexapanopeus caribbaeus; Marochi & Masunari 2011 as Acantholobulus caribbaeus).
Remarks. This is the first record of Acantholobulus caribbaeus from Espírito Santo state. This species was first described as a representative of the genus Micropanope, but upon erection of the genus Hexapanopeus Rathbun, 1898, it was transferred there as Hexapanopeus caribbaeus based on carapace shape (Rathbun 1898). However, recent revisions of the group suggested that this species is clearly separated from Hexapanopeus sensu stricto, and it is actually more closely related to Acantholobulus Felder & Martin, 2003. Therefore, H. caribbaeus was transferred to Acantholobulus (Thoma et al. 2009, 2014), and only recently adopted in WoRMS (2023). The values of the BLAST query cover (92%) and percent identity (>98%) were suitable for this identification, since our sequences aligned with other of the same species (EU863348, EU863381, EU863383, see Thoma et al. 2009) and with congeneric species, Acantholobulus bermudensis (Benedict & Rathbun, 1891) and A. schmitti (Rathbun, 1930) (MF490167, MF490168, see Mantelatto et al. 2018). Sequence accession number (GenBank): CCDB 7462—16S (OR501068) (present study).

description: We discuss the f(R)-theories of gravity with torsion in the framework of jet-bundles. Such an approach is particularly useful since the components of the torsion and curvature tensors can be chosen as fiber jet-coordinates on the bundles and then the symmetries and the conservation laws of the theory can be easily achieved. Field equations of f(R)-gravity are studied in empty space and in presence of various forms of matter as Dirac fields, Yang--Mills fields and spin perfect fluid. Such fields enlarge the jet-bundles framework and characterize the dynamics. Finally we give some cosmological applications and discuss the relations between f(R)-gravity and scalar-tensor theories.

description: In this paper, we propose a level set regularization approach combined with a split strategy for the simultaneous identification of piecewise constant diffusion and absorption coefficients from a finite set of optical tomography data (Neumann-to-Dirichlet data). This problem is a high nonlinear inverse problem combining together the exponential and mildly ill-posedness of diffusion and absorption coefficients, respectively. We prove that the parameter-to-measurement map satisfies sufficient conditions (continuity in the $L^1$ topology) to guarantee regularization properties of the proposed level set approach. On the other hand, numerical tests considering different configurations bring new ideas on how to propose a convergent split strategy for the simultaneous identification of the coefficients. The behavior and performance of the proposed numerical strategy is illustrated with some numerical examples.

description: The structure and design of optimal supply networks is an important topic in complex networks research. A fundamental trait of natural and man-made networks is the emergence of loops and the trade-off governing their formation: adding redundant edges to supply networks is costly, yet beneficial for resilience. Loops typically form when costs for new edges are small or inputs uncertain. Here, we shed further light on the transition to loop formation. We demonstrate that loops emerge discontinuously when decreasing the costs for new edges for both an edge-damage model and a fluctuating sink model. Mathematically, new loops are shown to form through a saddle-node bifurcation. Our analysis allows to heuristically predict the location and cost where the first loop emerges. Finally, we unveil an intimate relationship among betweenness measures and optimal tree networks. Our results can be used to understand the evolution of loop formation in real-world biological networks.
