description: We show how to construct homology bases for certain CW complexes in terms of discrete Morse theory and cellular homology. We apply this technique to study certain subcomplexes of the half cube polytope studied in previous works. This involves constructing explicit complete acyclic Morse matchings on the face lattice of the half cube; this procedure may be of independent interest for other highly symmetric polytopes.

description: What is the productivity of Science? Can we measure an evolution of the production of mathematicians over history? Can we predict the waiting time till the proof of a challenging conjecture such as the P-versus-NP problem? Motivated by these questions, we revisit a suggestion published recently and debated in the "New Scientist" that the historical distribution of time-to-proof's, i.e., of waiting times between formulation of a mathematical conjecture and its proof, can be quantified and gives meaningful insights in the future development of still open conjectures. We find however evidence that the mathematical process of creation is too much non-stationary, with too little data and constraints, to allow for a meaningful conclusion. In particular, the approximate unsteady exponential growth of human population, and arguably that of mathematicians, essentially hides the true distribution. Another issue is the incompleteness of the dataset available. In conclusion we cannot really reject the simplest model of an exponential rate of conjecture proof with a rate of 0.01/year for the dataset that we have studied, translating into an average waiting time to proof of 100 years. We hope that the presented methodology, combining the mathematics of recurrent processes, linking proved and still open conjectures, with different empirical constraints, will be useful for other similar investigations probing the productivity associated with mankind growth and creativity.

As an application, we give a complete classification of special triple planes, finding among others two nice families of K3 surfaces.

description: High-precision (sigma < 0.01) new JHK observations of 226 of the brightest and nearest red clump stars in the solar neighbourhood are used to determine distance moduli for the LMC. The resulting K- and H-band values of 18.47\pm0.02 and 18.49\pm0.06 imply that any correction to the K-band Cepheid PL relation due to metallicity differences between Cepheids in the LMC and in the solar neighborhood must be quite small.

description: A great deal of experimental work using perturbed angular correlation (PAC) has succeed in measuring hyperfine fields in Ce diluted in metallic systems, thus allowing the determination of the local impurity moment at low temperatures. Motivated by such experimental work on Ce(140) placed on a R site of the rare earth (R = Gd, Tb, Dy, Ho, Er) in RCo_2, we theoretically discuss, within a simple model, the local magnetic moments and thereby calculate the magnetic hyperfine fields. The results are in good agreement with the experimental data. For the sake of comparison we recall our previous results on Ta d-impurity embedded in the same hosts.

Στόχος είναι να παρουσιάσει την πορεία της προσχολικής αγωγής και εκπαίδευσης μέσα από το πρίσμα των πολιτικών, κοινωνικών και εκπαιδευτικών εξελίξεων του μεσοπολέμου, αλλά και μέσα από τη στάση και την κριτική του Τύπου της εποχής. Πιο συγκεκριμένα, επιχειρείται να προβληθεί ο ρόλος και η κατάρτιση των νηπιαγωγών, τα ιδρύματα προσχολικής αγωγής, καθώς και ο ρόλος που διαδραμάτισε το νηπιαγωγείο ως θεσμός γλωσσικής αφομοίωσης και πολιτισμικής ομογενοποίησης των ξενόφωνων πληθυσμών. Από μεθοδολογική άποψη, συνδυαστικά με δευτερογενείς πηγές, αξιοποιήθηκαν πρωτογενείς πηγές, κείμενα από εφημερίδες της εποχής και η βασική νομοθεσία του κράτους σχετικά με την εκπαιδευτική πολιτική της εποχής. Η ανάλυση των πηγών δείχνει ότι η προσχολική αγωγή και εκπαίδευση κατά την περίοδο του μεσοπολέμου είχε χαρακτήρα προνοιακό, αλλά, κυρίως, γλωσσικό και, επομένως, εθνικό σκοπό.
description: The present paper deals with the development of the Early Childhood Education during the Middle War in Greece with an emphasis on the area of Thessaloniki. The aim is to present the Early Childhood Education’s evolution through the prism of the political, social and educational developments of the Middle War period, but also through the aspect and criticism of the time’s Press. More specifically, an attempt is made to highlight the role and the education of kindergarten teachers, the preschool education institutions, as well as the role played by the kindergarten as an institution of linguistic assimilation and cultural homogenization of foreign-speaking populations. From a methodological point of view, besides secondary sources, archives of the time’s newspapers and the basic state’s legislation regarding the educational policy of the time were used. The analysis of the sources shows that Early Childhood Education during the Middle War period had a welfare character, but, above all, it had linguistic and, therefore, national purpose.

description: We investigate five different models for the dark matter halo bias, ie., the ratio of the fluctuations of mass tracers to those of the underlying mass, by comparing their cosmological evolution using optical QSO and galaxy bias data at different redshifts, consistently scaled to the WMAP7 cosmology. Under the assumption that each halo hosts one extragalactic mass tracer, we use a $χ^2$ minimization procedure to determine the free parameters of the bias models as well as to statistically quantify their ability to represent the observational data. Using the Akaike information criterion we find that the model that represents best the observational data is the Basilakos & Plionis (2001; 2003) model with the tracer merger extension of Basilakos, Plionis & Ragone-Figueroa (2008) model. The only other statistically equivalent model, as indicated by the same criterion, is the Tinker et al. (2010) model. Finally, we find an average, over the different models, dark matter halo mass that hosts optical QSOs of: $M_h\simeq 2.7 (\pm 0.6) \times 10^{12} h^{-1} M_{\odot}$, while the corresponding value for optical galaxies is: $M_h\simeq 6.3 (\pm 2.1) \times 10^{11} h^{-1} M_{\odot}$.

description: The tapped ions can be cooled close to their motional ground state, which is imperative in implementing quantum computation and quantum simulation. Here we demonstrate the capability of light-mediated chiral couplings between ions, which enables a superior cooling scheme exceeding the single-ion limit of sideband cooling. We present the chiral-coupling-assisted refrigeration in the target ion at the price of heating the others under asymmetric drivings, where its steady-state phonon occupation outperforms the lower bound set by a single ion. We further locate the optimal operation condition of the refrigeration and identify the parameter region where a faster rate of cooling emerges. Under an additional nonguided decay channel, the heating effect in the reciprocal coupling regime becomes suppressed and turns into cooling instead. Our results present a resource of collective chiral couplings which help surpass the bottleneck of cooling procedure in applications of trapped-ion-based quantum computer and simulator.

description: We present a novel approach for computing the Hilbert series of 4d N=1 supersymmetric QCD with SO(N_c) and Sp(N_c) gauge groups. It is shown that such Hilbert series can be recast in terms of determinants of Hankel matrices. With the aid of results from random matrix theory, such Hankel determinants can be evaluated both exactly and asymptotically. Several new results on Hilbert series for general numbers of colours and flavours are thus obtained in this paper. We show that the Hilbert series give rise to families of rational solutions, with palindromic numerators, to the Painlevé VI equations. Due to the presence of such Painlevé equations, there exist integrable Hamiltonian systems that describe the moduli spaces of SO(N_c) and Sp(N_c) SQCD. To each system, we explicitly state the corresponding Hamiltonian and family of elliptic curves. It turns out that such elliptic curves take the same form as the Seiberg-Witten curves for 4d N=2 SU(2) gauge theory with 4 flavours.

description: This paper proposes a new procedure to validate the multi-factor pricing theory by testing the presence of alpha in linear factor pricing models with a large number of assets. Because the market’s inefficient pricing is likely to occur to a small fraction of exceptional assets, we develop a testing procedure that is particularly powerful against sparse signals. Based on the high-dimensional Gaussian approximation theory, we propose a simulation-based approach to approximate the limiting null distribution of the test. Our numerical studies show that the new procedure can deliver a reasonable size and achieve substantial power improvement compared to the existing tests under sparse alternatives, and especially for weak signals.

description: We suggest a novel source of polarization-entangled photon pairs based on a cross-shaped plasmonic nanoantenna driven by a single quantum dot. The integration of the nanoantenna with a metal mirror overcomes the fundamental tradeoff between the spontaneous emission (SE) enhancement and the extraction efficiency typical of microcavity and nanowire-based architectures. With a very-high extraction efficiency of entangled photons (~90%) at 1.55 um and large SE enhancement (~90) over a broad 330 nm spectral range, the proposed design will pave the way toward reliable integrated sources of nonclassical light.

description: We report computer simulation studies of the kinetics of ordering of a two dimensional system of particles on a template with a one dimensional periodic pattern. In equilibrium one obtains a re-entrant liquid-solid-liquid phase transition as the strength of the substrate potential is varied. We show that domains of crystalline order grow as $\sim t^{1/z}$, with $z \sim 4$ with a possible cross-over to $z \sim 2$ at late times. We argue that the $t^{1/4}$ law originates from {\em single-file} motion and annihilation of defect pairs of opposite topological charge along channels created by the template.

title: Land tenure formalisation in Dar es Salaam: institutional transition through endogenous social interactions
Creators: name: Manara, Martina
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: This thesis investigates the implementation of two land titling projects offering interim and full statutory property rights in Dar es Salaam, Tanzania. As in many other African cities, these projects encounter severe challenges of implementation and the land management remains predominantly informal. This work examines how local institutions, social relations and public authority affect the transition to formal property. The thesis is composed of four papers drawing on interdisciplinary literature and an innovative combination of methods. Papers 1 and 2 examine how social relations influence the demand for interim property rights. Using econometric analysis of administrative data, paper 1 finds evidence of neighbourhood effects suggesting that neighbours influence their early choices of formalisation. Through institutional analysis and primary survey data, paper 2 concludes that coordination is the result of an informal institution: a descriptive norm that prescribes formalisation conditional on the behaviour and advice of others. Papers 3 and 4 interrogate the role of the local public authority for the construction of and the transition to formal property. Based on in-depth interviews and ethnographic data, paper 3 shows that local leaders are essential to legitimise and operationalise the formal property apparatus, specifically the cadastral map and database. Drawing on two lab-in-the-field experiments, paper 4 suggests that leaders hold accurate knowledge on the local demand for full statutory rights, which could be leveraged to inform better pricing strategies. Overall, the thesis contributes to an institutional approach to land tenure formalisation by quantifying and qualifying how endogenous social interactions mediate the transition to formal property. In so doing, the study adds to literature on the implementation of urban land titling policies, the demand for land titles and the formality-informality nexus in developing cities. Furthermore, the thesis provides policy recommendations of current relevance as urban formalisation remains a key government priority.

An efficient interest management system for networked virtual environment

Publisher: name: University of British Columbia
Year: 2010

description: Over the past decades we have witnessed an enormous development in multiplayer games. They have evolved from the initial state with two players on the same computer to the current state with tens of thousands simultaneous players in a virtual world via the Internet. In dealing with the large scale of massive multiplayer on-line games (MMOGs), various peer-to-peer (P2P) solutions have been proposed. Although they have improved the scalability of MMOGs in various degrees, they encounter new serious challenges in interest management. No existing works have provided a satisfying solution though they all have some attractions. In this thesis, we propose a fully distributed P2P infrastructure to achieve interest management for MMOGs. Our system divides the virtual game world into cells. Players in each cell are connected to the cell’s master-node that is selected from the players in the cell. Master-nodes are also connected with master-nodes of adjacent cells, forming a backbone network. Players provide information about their position and area of interest (AOI) to their master-node. The master-node informs the players in the cell about which other players are in their AOI so that the players can obtain game updates directly from players in their AOI. A routing scheme is applied on top of the backbone network so that master-nodes can efficiently exchange information about nodes in each cell. To help players to locate master-node of each cell, a distributed hash table (DHT) is used for bookkeeping. As illustrated by our experiments, our proposed system is not only scalable and effective; it also provides the benefits of high responsiveness and reliability without compromising any game features.

description: To investigate the actual phenomena of transport on a complex network, we analysed empirical data for an inter-firm trading network, which consists of about one million Japanese firms and the sales of these firms (a sale corresponds to the total in-flow into a node). First, we analysed the relationships between sales and sales of nearest neighbourhoods from which we obtain a simple linear relationship between sales and the weighted sum of sales of nearest neighbourhoods (i.e., customers). In addition, we introduce a simple money transport model that is coherent with this empirical observation. In this model, a firm (i.e., customer) distributes money to its out-edges (suppliers) proportionally to the in-degree of destinations. From intensive numerical simulations, we find that the steady flows derived from these models can approximately reproduce the distribution of sales of actual firms. The sales of individual firms deduced from the money-transport model are shown to be proportional, on an average, to the real sales.

description: With the widespread adoption of deep learning, reinforcement learning (RL) has experienced a dramatic increase in popularity, scaling to previously intractable problems, such as playing complex games from pixel observations, sustaining conversations with humans, and controlling robotic agents. However, there is still a wide range of domains inaccessible to RL due to the high cost and danger of interacting with the environment. Offline RL is a paradigm that learns exclusively from static datasets of previously collected interactions, making it feasible to extract policies from large and diverse training datasets. Effective offline RL algorithms have a much wider range of applications than online RL, being particularly appealing for real-world applications, such as education, healthcare, and robotics. In this work, we contribute with a unifying taxonomy to classify offline RL methods. Furthermore, we provide a comprehensive review of the latest algorithmic breakthroughs in the field using a unified notation as well as a review of existing benchmarks' properties and shortcomings. Additionally, we provide a figure that summarizes the performance of each method and class of methods on different dataset properties, equipping researchers with the tools to decide which type of algorithm is best suited for the problem at hand and identify which classes of algorithms look the most promising. Finally, we provide our perspective on open problems and propose future research directions for this rapidly growing field.

description: The computationally-efficient solution of multi-objective optimization problems (MOPs) arising in the design of modern electromagnetic (EM) microwave devices is addressed. Towards this end, a novel System-by-Design (SbD) method is developed to effectively explore the solution space and to provide the decision maker with a set of optimal trade-off solutions minimizing multiple and (generally) contrasting objectives. The proposed MO-SbD method proves a high computational efficiency, with a remarkable time saving with respect to a competitive state-of-the-art MOP solution strategy, thanks to the "smart" integration of evolutionary-inspired concepts and operators with artificial intelligence (AI) and machine learning (ML) techniques. Representative numerical results are reported to provide the interested users with useful insights and guidelines on the proposed optimization method as well as to assess its effectiveness in designing mm-wave automotive radar antennas.

We show that orthogonal ring patterns are governed by the same equation as circle patterns. For every ring pattern there exists a one parameter family of patterns that interpolates between a circle pattern and its dual. We construct ring patterns analogues of the Doyle spiral, Erf and za functions. We also derive a variational principle and compute ring patterns based on Dirichlet and Neumann boundary conditions.

description: Extracting classical information from quantum systems is an essential step of many quantum algorithms. However, this information could be corrupted as the systems are prone to quantum noises, and its distortion under quantum dynamics has not been adequately investigated. In this work, we introduce a systematic framework to study how well we can retrieve information from noisy quantum states. Given a noisy quantum channel, we fully characterize the range of recoverable classical information. This condition allows a natural measure quantifying the information recoverability of a channel. Moreover, we resolve the minimum information retrieving cost, which, along with the corresponding optimal protocol, is efficiently computable by semidefinite programming. As applications, we establish the limits on the information retrieving cost for practical quantum noises and employ the corresponding protocols to mitigate errors in ground state energy estimation. Our work gives the first full characterization of information recoverability of noisy quantum states from the recoverable range to the recovering cost, revealing the ultimate limit of probabilistic error cancellation.

Environmental Determinants Of Health: A Study Of Problem Gambling In Montreal

description: Social and physical environments provide settings that can be more or less supportive of risky behaviours. The form of gambling linked most strongly to problem gambling, video lottery terminal (VLT) use, is used to study the link between environment and behaviour. First, people living closer to VLTs were hypothesized to be more likely to gamble due to greater accessibility. Second, social mechanisms, such as social norms, were hypothesized to cause spatial clustering of gambling prevalence rates. Data from a telephone survey of Montreal residents (Ladouceur 2004) were modeled hierarchically in a logistic multilevel model with 2007 individuals in 49 residential areas. Results show that respondents living in the bottom tertile of physical accessibility are almost half as likely to use VLTs as the remaining respondents. Also, VLT use prevalence rates show spatial clustering, even after controlling for compositional characteristics and physical accessibility. Environmental factors, both physical and social, are deemed to be intrinsic to problem gambling etiology and to health in general.

description: We defne the resource non-increasing (RNI) framework to study the dynamical resource theory. With such a defnition, we propose several potential quantifcation candidates under various free operation sets. For explicit demonstrations, we quantify the quantum dynamical coherence in the scenarios with and without post-selective measurements. Correspondingly, we show that maximally incoherent operations (MIO) and incoherent operations (IO) in the static coherence resource theory are free in the sense of dynamical coherence. We also provide operational meanings for the measures by the quantum discrimination tasks. Moreover, for the dynamical total coherence, we also present convenient measures and give the analytic calculation for the amplitude damping channel.

subject: Public health nutrition

description: Undernutrition affects millions of children in low- and middle- income countries, causing poor growth, poor development, and increased risk of mortality. Many nutrition-sensitive interventions for rural areas increase household access to nutritious foods through increasing home production, a strategy that has small positive effects on child diets. However, there is growing evidence that local markets are also important for dietary quality. Despite the importance of rural markets, the rural food environment and food purchasing practices among rural households are not well-characterized in the literature. It is possible that promoting improved household food purchase practices is an effective method for improving child nutrition in rural areas. Tanzania experiences a high prevalence of undernutrition among children under the age of 5 years, particularly among rural populations. This dissertation utilizes data from the Engaging Fathers for Effective Child Nutrition and Development in Tanzania (EFFECTS), a cluster randomized controlled trial that was conducted in rural Mara, Tanzania. The EFFECTS trial promoted improved diets through both home production and through food purchases through a social and behavior change strategy. We measured changes in dietary diversity (a proxy for diet quality), children’s nutrient intake adequacy, and diversity of foods purchased and produced. This dissertation presents evidence that food purchase diversity is positively associated with dimensions of the rural food environment, including high market food diversity (+0.37 food groups, p=0.01), living within 30 minutes of a market (+0.36 food groups, p=0.001) and household purchasing power (+0.14 food groups per additional million Tanzanian shillings spent by the household, p<0.001). In turn, purchase diversity is positively associated with dietary diversity (b=0.22, p<0.001), and intake adequacy of folate, vitamin B12, and calcium (all p<0.05) among children 9-23 months. Promoting food purchase diversity was effectively integrated into the EFFECTS interventions, resulting in purchasing +0.54 food groups at endline compared to changes in the control (p<0.01), which mediated 25% of the total improvement in child dietary diversity. In contrast, production diversity was associated with increased intake adequacy of vitamin A only (p<0.05), households produced +0.44 food groups at endline compared to control (p<0.05), and this mediated 15% of the total improvement in child dietary diversity. These findings suggest that promoting diverse food purchases, alongside diverse home production, is an effective way to improve children’s diets in similar settings.

Troubling talk, unsettling silence: the discourse of an inclusive community planning group

description: Community development for social justice requires the communication, representation and participation of people at the margins of civil society. The manner in which such communications and representations are heard and answered is critical. Despite many attempts at inclusive community planning and communication across differences, the transformative and democratic outcomes that are sought frequently remain elusive. Rather, the emphasis on cultural diversity habitually leads to a superficial reading of difference that obscures power relations and upholds dominant cultural norms. Little is known regarding how inclusive community planning groups' responses to subordinate groups are socially organised in ways that maintain normative power arrangements, how these arrangements are resisted, and how they are changed. Rarely examined in the literature of inclusive community planning are either, its underlying politics and theories of power, the construction and representation of members' identities, methods of knowledge production, or its communications and silences. This study explores how power is expressed, acknowledged, resisted, and reshaped in the discourse of an ICPG whose minority members had disabilities. A critical discourse analysis of an instrumental case study is presented that is informed by feminist, postmodern and critical theories, and based on data gathered using observation, videotape, documents, and in-depth interviewing. The findings, illustrated with five transcriptions of video clips, show how power circulated among members, positioned them differently, constructed some knowledge as authentic and discarded other knowledge. Discursive practices formed a set of rules that regulated what should be represented and how representation should be made. Knowledge based on personal experience of disability was disallowed and epistemic privilege was withheld from members with disabilities. A final dictum prevented the overt expression of conflict and dissent, therefore, members voiced their concerns in indirect and ambiguous ways. These disciplinary techniques strengthened the dominant discourse of non disabled representatives, and promoted their interests, but not without struggle and resistance expressed in a discourse of self-advocacy from members with disabilities. Power's inscription of embodiment, impairment/disability, knowledge, and silence in relation to wider sociocultural practice is discussed, as well as methodological implications raised by the study. Recommendations for improved practice are suggested.

description: Silicon (Si) is a beneficial plant nutrient with the potential to make plants tolerant to biotic and abiotic stresses; however, it’s effect on improve yield and Si uptake in maize at Ganges delta coastal zone soils has not been investigated. The purpose of the study was to find out the contribution of Si to improve maize yield and Si uptake especially under nutrient deficit conditions. A field experiment was conducted in dry season of 2021 and 2022 using a popular maize variety Don-111. The experiment was laid out in two factors randomized complete block design having two levels of Si (0 and 20 kg Si ha−1 rate as sodium metasilicate), and four levels of NPK fertilizers (40%, 60%, 80% and 100%). The 100% NPK indicates 225:60:80 kg ha−1 N:P:K, respectively. In 2021 the 20 kg Si ha−1 rate with 40%, 60%, 80, and 100% NPK rate recorded grain yield of 7.52, 8.73, 9.95 and 11.16 t ha−1, respectively which was 17.9%, 15.0%, 8.6%, and 7.8% higher, and in 2022 the grain yield of 6.31, 7.82, 8.83 and 9.62 t ha−1, which was 28.0%, 16.4%, 16.3%, and 6.3%, respectively, higher than the respective control treatment. All other growth, yield and yield contributing characters, and Si content in plant was improved by Si application, however, the maximum cases rate of increment was higher in lower rates of NPK fertilizers. Silicon application is therefore recommended for the improvement of maize growth and yield at the eastern Ganges delta coastal plains.

description: We investigate the category of finite-dimensional representations of twisted hyper loop algebras, i.e., the hyperalgebras associated to twisted loop algebras over finite-dimensional simple Lie algebras. The main results are the classification of the irreducible modules, the definition of the universal highest-weight modules, called the Weyl modules, and, under a certain mild restriction on the characteristic of the ground field, a proof that the simple modules and the Weyl modules for the twisted hyper loop algebras are isomorphic to appropriate simple and Weyl modules for the non-twisted hyper loop algebras, respectively, via restriction of the action.

description: The Path-Dependent Neural Jump Ordinary Differential Equation (PD-NJ-ODE) is a model for predicting continuous-time stochastic processes with irregular and incomplete observations. In particular, the method learns optimal forecasts given irregularly sampled time series of incomplete past observations. So far the process itself and the coordinate-wise observation times were assumed to be independent and observations were assumed to be noiseless. In this work we discuss two extensions to lift these restrictions and provide theoretical guarantees as well as empirical examples for them. In particular, we can lift the assumption of independence by extending the theory to much more realistic settings of conditional independence without any need to change the algorithm. Moreover, we introduce a new loss function, which allows us to deal with noisy observations and explain why the previously used loss function did not lead to a consistent estimator.

description: In this paper, we propose a self-consistent test for a Hubble constant estimate using galaxy cluster and type Ia supernovae (SNe Ia) observations. The approach consists, in a first step, of obtaining the observational value of the galaxy cluster scaling-relation $Y_{SZE}D_{A}^{2}/C_{XSZ}Y_X = C $ by combining the X-Ray and SZ observations of galaxy clusters at low redshifts ($z < 0.1$) from the first {\it Planck mission} all-sky data set ($0.044 \leq z \leq 0.444$), along with SNe Ia observations and making use of the cosmic distance duality relation validity. Then, by considering a flat $Λ$CDM model for $D_A$, the constant $C$ from the first step and the Planck prior on $Ω_M$ parameter, we obtain $H_0$ by using the galaxy cluster data with $z>0.1$. As a result, we obtain $H_0 = 73.014^{+7.435}_{-6.688}$ km/s/Mpc, which represents $9.7\%$ accuracy measurement on the Hubble constant.. We also compare our method with that one where the $C$ parameter is obtained from hydrodynamical simulations of massive galaxy clusters.

What the Oblique Parameters S, T, and U and Their Extensions Reveal About the 2HDM: A Numerical Analysis

description: The oblique parameters S, T, and U and their higher-order extensions (V, W, and X) are observables that combine electroweak precision data to quantify deviation from the Standard Model. These parameters were calculated at one loop in the basis-independent CP-violating Two-Higgs Doublet Model (2HDM). The scalar parameter space of the 2HDM was randomly sampled within limits imposed by unitarity and found to produce values of the oblique parameters within experimental bounds, with the exception of T. The experimental limits on T were used to predict information about the mass of the charged Higgs boson and the difference in mass between the charged Higgs boson and the heaviest neutral Higgs boson (m_ch - m_3). In particular, it was found that the 2HDM predicts -600 GeV < m_ch - m_3 < 100 GeV, with values of m_ch > 250 GeV being preferred. The mass scale of the new physics produced by random sampling was consistently fairly high, with the average of the scalar masses falling between 400 and 800 GeV for Y_2 = m_W^2, although the model can be tuned to produce a light neutral Higgs mass (eg, 120 GeV). Hence, the values produced for V, W, and X fell well within .01 of zero, confirming the robustness of the linear expansion approximation. Taking the CP-conserving limit of the model was found to not significantly affect the values generated for the oblique parameters.
