description: The quantum Fourier transform (QFT) brings efficiency in many respects, especially usage of resource, for most operations on quantum computers. In this study, the existing QFT-based and non-QFT-based quantum arithmetic operations are examined. The capabilities of QFT-based addition and multiplication are improved with some modifications. The proposed operations are compared with the nearest quantum arithmetic operations. Furthermore, novel QFT-based subtraction, division and exponentiation operations are presented. The proposed arithmetic operations can perform nonmodular operations on all signed numbers without any limitation by using less resources. In addition, novel quantum circuits of two's complement, absolute value and comparison operations are also presented by using the proposed QFT-based addition and subtraction operations.

description: We use a hadron resonance gas model to study the QCD phase diagram at nonzero temperature, baryon, isospin and strangeness chemical potentials. We determine the temperature of the transition from the hadronic phase to the quark gluon plasma phase using two different methods. We find that the critical temperatures derived in both methods are in very good agreement. We find that the critical surface has a small curvature. We also find that the critical temperature's dependence on the baryon chemical potential at zero isospin chemical potential is almost identical to its dependence on the isospin chemical potential at vanishing baryon chemical potential. This result, which holds when the chemical potentials are small, supports recent lattice simulation studies. Finally, we find that at a given baryon chemical potential, the critical temperature is lowered as either the isospin or the strangeness chemical potential are increased. Therefore, in order to lower the critical temperature, it might be useful to use different isotopes in heavy ion collision experiments.

description: Feeling lonely motivates people to reconnect with others, but it can also trigger a vicious cycle of cognitions and behaviours that reinforces their loneliness. In this study, we examined the behavioural consequences of loneliness in a virtual social environment. A total of 176 participants navigated a character (protagonist) through a two-dimensional browser game and rated the character's loneliness multiple times during the game. In the first part of the game, another character is introduced as the protagonist's spouse. At one point, the spouse leaves for an undetermined period of time but later returns. Immediately before this separation, higher ascribed loneliness of the protagonist was associated with more frequent interactions with the spouse. After the reunion, however, higher ascribed loneliness was associated with less frequent interactions with the spouse. Ascribed loneliness was not significantly related to the frequency of interactions with others nor to the frequency of solitary activities. These patterns held after controlling for ascribed positive affect. Participants' levels of loneliness were related to the level of ascribed loneliness only when the spouse was present but not when the spouse was absent. In sum, these findings suggest that the conditions that trigger the vicious cycle of loneliness are person- and situation-specific.

description: The drug discrimination paradigm was used to investigate the effects of combinations of d-amphetamine sulfate (amph) and alcohol (etoh). Rats were trained to discriminate between the stimulus properties of 1.2 mg/kg amph and non-drug treatment in a two-lever food-motivated operant task. Once trained, rats were tested with .3 mg/kg amph, and showed an intermediate level of "amphetamine" responding. Combinations of this test dose with etoh 150 mg/kg or 300 mg/kg produced significantly increased amph-appropriate responding. This potentiation of the amph cue tended to be higher at etoh 150 mg/kg. The administration of etoh (150 or 300 mg/kg) alone did not result in amph-appropriate responding. These findings confirm earlier results from both drug discrimination and other behavioral paradigms, indicating that low doses of etoh in combination with low doses of amph can result in potentiation of amph effects.

description: The processing of fruits and vegetables, in the Caribbean context, should have the objective of exploiting the inherent conditionlow capitalization, abundant tropical heat, and fruits and vegetables possessing some of the world's most exotic flavors. The region's chronically low level of funding precludes elaborate processing facilities in many of the island states and territories. Fortunately, success does not necessarily correlate with the magnitude of the investment, and size and quality are not synonymous. All fruits may be "candied" by simple, natural or artificial dehydration; all juices can be easily fermented into wine; all starchy vegetables can be readily converted to "instant" flakes, meals and powders. These processes are examples of relatively inexpensive technologies that are capable of adding high value to cheap produce. Universal models, seldom adaptable to small-scale production, will fail, given the region's limiting population size and rawmaterials resource base. Unique Caribbean models, of the order of cottage industries, relying principally on the indigenous and regional markets, accordingly modified to accommodate the cheapest means of inter-island transport, need to be advanced. Continental trade will inevitably follow. First principles of such a model should be good manufacturing practices, common regulatory standards, and enforcement mechanisms.
Magnetic and medicinal properties of lanthanides
Creators: name: Barta, Cheri A.
Publisher: name: University of British Columbia
Year: 2011

description: Two distinct projects involving the use of lanthanide metal ions are discussed in this thesis. In the first study, the magnetic interactions in heterometallic d/f complexes were investigated. The most powerful permanent magnet known to date consists of a Nd-Fe core; however, the magnetic exchange between these two metal ions is poorly understood. By purposeful design, new cationic d/f complexes using a multidentate amine phenol ligand were synthesized that selectively coordinate divalent first row d-block transition metal ions (TM) and lanthanides (Ln) in close proximity, a feature desirable for magnetic studies. The synthesis, characterization, and magnetic studies of the d/f cluster complexes with the formula [LnTM₂(bcn)₂]⁺, where H₃bcn = tris-N,N',N" -(2-hydroxybenzyl)-1,4,7-triazocyelononane), TM(II) = Zn, Cu and Ni, and Ln(III)= La, Nd, Gd, Dy and Yb are discussed herein. In addition, the core structure of [TM(Hbcn)], [TM₂(bcn)₃], [La(bcn)], and [La₃(bcn)₂] have been examined. Select magnetic studies were also completed on a similar trimetallic d/f species, [LnNi₂(tam)₂]⁺, where H₃tam = tris-1,1,1-(((2-hydroxybenzyl)amino) methyl)ethane, and Ln(III) = Gd, Dy and Yb, used to compare the magnetic behaviors between geometrically diverse TM(II)-Ln(III) systems. The second study illustrates the usefulness of Ln(III) in metallopharmaceuticals. La(III) ions are known to be functional mimics of Ca(II) ions and have been shown to affect the bone remodeling cycle. Exploiting this disruption to the homeostasis of bone has potential for the treatment of bone density disorders, such as osteoporosis. In an effort to find new orally active agents for these disorders, a series of Ln(III) containing complexes incorporating small, non-toxic, bidentate pyrone and pyridinone ligands have been synthesized and characterized (LnL₃, Ln(III) = La, Eu, Gd, Tb, Yb, L = 3-oxy-2-methyl-4-pyrone (ma-), 3-oxy-2-ethyl-4-pyrone (ema-), 3-oxy-1,2-dimethyl-4-pyridinone (dpp-) and 3-oxy-2-methyl-4(1H)-pyridinone (mpp-)). Preliminary biological analyses undertaken in this thesis include cytotoxicity, cell uptake and bidirectional transport studies in Caco-2 cells and in vitro hydroxyapatite (HA) binding studies analyzed by ICP-MS, fluorescence assays, UV-vis spectrophotometric assays and IR. The LnL₃ species were found to have IC₅₀ values at least 6 times greater than that of cisplatin, ≥98% HA-binding capacity, and permeability coefficients in the moderate range.

description: Der Alltag von Schülerinnen und Schülern mit schweren und mehrfachen Behinderungen ist oft durch kommunikative Hürden geprägt, da sie sich in den meisten Fällen nicht in der Form ausdrücken können, die unmittelbar und konkret vom Umfeld verstanden wird. Hinweise auf die aktuelle Befindlichkeit komplexbehinderter Lernenden, welche sich anhand ausgesendeter Zeichen und Signale abbildet, zu erwerben, ist eine wichtige Aufgabe und zentrale Herausforderung der Bezugspersonen, die eine aufmerksame Beobachtung voraussetzt. Mithilfe von Videoaufnahmen und Interviews werden in der vorliegenden Arbeit zwei Fälle hinsichtlich aktueller Befindlichkeit untersucht. Dabei wird erforscht, welche Kriterien für die Einschätzung des aktuellen Befindens einer Schülerin und eines Schülers in ausgewählten Schulsituationen von verschiedenen Bezugspersonen Beachtung finden. Mittels einzelner Ausschnitte dieser Schulsituationen werden in den Interviews festgehaltene Aussagen einander gegenübergestellt. Zudem bilden die von den Bezugspersonen beachteten Kommunikationskanäle, welche die Grundlage für Befindlichkeitseinschätzung darstellt, einen weiteren Gegenstand der Untersuchung. Die vorliegende Einzelfallstudie verdeutlicht, dass die Probandin und der Proband trotz ihrer komplexen Beeinträchtigung, die mit einer starken Einschränkung der Kommunikationsmittel einhergeht, in der Lage sind, eine grosse Auswahl an unterschiedlichen Signalen auszusenden. Bezüglich Aussagekraft der Signale, fand die Mimik, gefolgt vom Tonus für die Einschätzung der Befindlichkeit durch die Bezugspersonen am meisten Aufmerksamkeit.

description: In this Master's thesis the performance of a heat delivery system of an energy efficient single-family house located in Zwettl, Lower Austria, is investigated. Over the course of ten months, in which the building was inhabited, monitoring data of the heat delivered to the floor and brick walls was collected. Using these data, a detailed analysis of the building's performance is presented. In particular, it is compared to the simulation model that was created during the design phase of the house. It turns out that the design phase model is rather inaccurate and often does not match the actual behavior. Consequently, this simulation model is investigated and enhanced. Particular improvements concern the following input parameters of the building regime: set temperature points, natural ventilation, infiltration, internal heat gains and weather data. Most of these are based on the actual user behavior, which was derived from additional sensors in the building (e.g. temperature, CO2 concentration, etc.). The results are presented by comparing the improved simulation to the design phase model and to the actual monitoring data in a monthly evaluation. The particular influence of each mentioned parameter is analyzed and discussed separately. It is shown that the enhanced simulation much more accurately models the reality.
Foreign Exchange Rationing and Wheat Markets in Ethiopia

description: In spite of remarkable growth in Ethiopia’s agricultural production and overall real incomes (GDP/capita) from 2004/05 to 2008/09, prices of major cereals (teff, maize, wheat and sorghum) have fluctuated sharply in both nominal and real terms. International prices of cereals also fluctuated widely, particularly between 2006 and 2008. However, the links between Ethiopia’s domestic cereal markets and the international market are by no means straightforward. Among the major staples, only wheat is imported or exported on a significant scale. And frequent changes in trade and macro-economic policies, movements in international prices and fluctuations in domestic production have at times eliminated incentives for private sector imports of wheat. From July 2005 to March 2007, private sector wheat imports were profitable and domestic wheat prices closely tracked import parity prices. Then, from April 2007 to May 2008, good domestic harvests coincided with increase international wheat prices, so private sector wheat imports were no longer profitable. Most recently, rationing of foreign exchange for imports effectively stopped private sector wheat imports beginning in about April 2008. Partial equilibrium analysis shows,however, that government imports and sales in 2008-09 effectively increased domestic supply and lowered market wheat prices. These sales at the low official price also implied that recipient households, traders and flour mills enjoyed a significant subsidy. Allowing the private sector access to foreign exchange for wheat imports or auctioning government wheat imports in domestic markets would eliminate these rents and generate additional government revenue, while having the same effect on market prices as government subsidized sales.

description: Thermodynamic characteristics of Fermi systems are investigated in the vicinity of a phase transition where the effective mass diverges and the single-particle spectrum becomes flat. It is demonstrated that at extremely low temperatures $T$, the flattening of the spectrum is reflected in non-Fermi-liquid behavior of the inverse susceptibility $χ^{-1}(T) \sim T^α$ and the specific heat $C(T)/T\sim T^{-α}$, with the critical index $α=2/3$. In the presence of an external static magnetic field $H$, both these quantities are found to exhibit a scaling behavior, e.g. $χ^{-1}(T,H)=χ^{-1}(T,0)+ T^{2/3}F(H/T)$, in agreement with available experimental data.

description: The thermal properties of hydrodynamical simulations of galaxy clusters are usually compared to observations by relying on the emission-weighted temperature T_ew, instead of on the spectroscopic X-ray temperature T_spec, which is obtained by actual observational data. In a recent paper Mazzotta et al. show that, if the cluster is thermally complex, T_ew fails at reproducing T_spec, and propose a new formula, the spectroscopic-like temperature, T_sl, which approximates T_spec better than a few per cent. By analyzing a set of hydrodynamical simulations of galaxy clusters, we find that T_sl is lower than T_ew by 20-30 per cent. As a consequence, the normalization of the M-T_sl relation from the simulations is larger than the observed one by about 50 per cent. If masses in simulated clusters are estimated by following the same assumptions of hydrostatic equilibrium and β--model gas density profile, as often done for observed clusters, then the M-T relation decreases by about 40 per cent, and significantly reduces its scatter. Based on this result, we conclude that using the observed M-T relation to infer the amplitude of the power spectrum from the X-ray temperature function could bias low σ_8 by 10-20 per cent. This may alleviate the tension between the value of σ_8 inferred from the cluster number density and those from cosmic microwave background and large scale structure.

description: The emphasis of this paper is on crops that hold potential for increased production for export markets. The criteria on which crop selection is based are: increasing markets in USA, Canada and EC, and experience of production within the region. Figures for market size and existing production are given. The major non-traditional export earning crops for which the market is expanding at present are identified as mango, avocado, hot pepper, ginger, melon and pineapple. In addition, papaya is identified as a crop which is traditionally produced in the region, and for which the market is expanding rapidly. Tissue culture techniques are particularly useful in the development of improved varieties of papaya, ginger and pineapple, and details of these techniques are given. For papaya, micropropagated plants bear earlier and frequent replanting may allow good production despite the presence of disease organisms. Ginger cannot be improved by traditional breeding programmes and tissue culture techniques include the use of colchicine to double chromosome numbers, thus producing larger rhizomes. For pineapples, micropropagation allows the rapid propagation of new varieties, and the costs of producing plants this way are outlined.

description: Evolutionary scenarios suggest that the progenitor of the new binary pulsar J0737-3039B \cite{ref1,ref2} was a He-star with $M > 2.1-2.3~\Ms$ \cite{ref3,ref4}. We show that this case implies that the binary must have a large ($>120$ km/s) center of mass velocity. However, the location, $\sim 50$ pc from the Galactic plane, suggests that the system has, at high likelihood, a significantly smaller center of mass velocity and a progenitor more massive than 2.1~$\Ms$ is ruled out (at 97% c.l.). A progenitor mass around 1.45~$\Ms$, involving a new previously unseen gravitational collapse, is kinematically favored. The low mass progenitor is consistent with the recent scintillations based velocity measurement of 66$\pm 15$ km/s \cite{ref12new} (and which also rules out the high mass solution at 99% c.l.) and inconsistent with the higher earlier estimates of 141$\pm 8.5$ km/s \cite{ref11new}. Direct proper motion measurements, that should be available within a year or so, should better help to distinguish between the two scenarios.

Mechanisms and engineering of glycosyltransferases
Creators: name: Lairson, Luke Lee
Publisher: name: University of British Columbia
Year: 2011

description: In order to gain insight into the natural evolution of enzyme mechanism and to increase the utility of a class of sugar modifying enzymes known as glycosyltransferases, several representative enzymes were subjected to mechanistic and engineering studies. The chemical and kinetic mechanisms of the GT-A fold inverting sialyltransferase Cst II were investigated by detailed kinetic analysis, protein X-ray crystallography and mutagenesis. This enzyme catalyzes the general SN[subscript]2-like direct displacement mechanism used by all inverting glycosyltransferases. However, the chemical strategies utilized to facilitate reaction are more akin to those of the GT-B fold enzymes, indicating a convergence in mechanism between these two clans of enzymes. By analogy to retaining glycosidases, retaining glycosyltransferases had been thought to use a double displacement mechanism involving an enzymatic nucleophile. However, a comparison of the X-ray crystal structures of multiple retaining glycosyltransferases indicates a complete lack of conserved structural architecture in the region that would be occupied by this critical catalytic residue. This lack of conserved architecture, precedence for cationic enzymatic mechanisms, and the inherent differences in reactivities of glycosyltransferase and glycosidase substrates all support a notion that the majority of retaining glycosyltransferases utilize a mechanism involving the formation of a short-lived ion pair intermediate species. However, a protein engineering approach was used to explore the possibility of nucleophilic catalysis in the retaining galactosyltransferase LgtC. The results of this work led to the first direct observation of a catalytically relevant covalent glycosyl-enzyme intermediate for a retaining glycosyltransferase. It was demonstrated that catalytically active LgtC could be displayed on the surface of M13 bacteriophage as a pIII fusion protein. Further, LgtC phage display was successfully performed in the context of a water-in-oil emulsification procedure that may have significant utility in the development of directed evolution screening approaches. A substrate engineering strategy was developed which allowed the substrate specificity of wild type LgtC to be broadened to allow exclusive formation of α-1,2, α-1,3 or α-1,4 linkages at synthetically useful rates with various alternative acceptor substrates. Finally, it was demonstrated that Cst II and LgtC will utilize alternative donor substrates in the presence of their respective natural nucleotide products.

description: The effect of the long-range Coulomb interaction on charge accumulation in antiferromagnetic vortices in high-Tc superconductors is studied within a Bogoliubov-de Gennes mean-field model of competing antiferromagnetic and d-wave superconducting orders. Antiferromagnetism is found to be associated with an accumulation of charge in the vortex core, even in the presence of the long-range Coulomb interaction. The manifestation of Pi-triplet pairing in the presence of coexisting dSC and AFM order, and the intriguing appearance of one-dimensional stripe-like ordering are discussed. The local density of states (LDOS) in the vortex core is calculated and is found to be in excellent qualitative agreement with experimental data.

description: By applying techniques of molecular biology, scientists can genetically transform plants to reduce their size. Reduction in size is possible through the incorporation and expression of the rolC gene. The rolC gene was isolated from the Agrobaclerium rhizogenes that causes the 'hairy root' disease in plants. The product of the ro!C gene metabolizes the inactive form of cytokinin in the plant cell to an active form. The increased cellular concentration of the active form of cytokinin causes a shorter internodal length and a reduced apical dominance which increases branching. Fertile transgenic plants have been obtained with a 25% reduction in height. The development of dwarf or semidwarf fruit trees through the incorporation of the rolC gene would reduce costs associated with pruning, pest control and harvesting.

The principles of a circular economy orientate business structures to provide appropriate conditions for redesigning their products at the system level, which, after use, will be ready for reuse or recycling. It has been substantiated that the implementation of the principles of the circular economy makes it possible to identify new sources of value creation and the possibility of obtaining additional profit for business structures: the level of consumption of materials compared to the linear production system is significantly lower; savings by increasing the maximum number of consecutive cycles and saving time for each of these cycles; diversifying the reuse of resources throughout the value chain; the use of environmentally friendly raw materials increases the efficiency of business structures, increases product durability and material productivity. All of this will ensure a high level of environmental protection and reduce the primary need of manufacturing enterprises for external resources. Consequently, the concept of a circular economy constitutes a reliable basis for rethinking business processes in entrepreneurship, contributes to the improvement of the environmental situation, and therefore, the search and implementation of appropriate business models.

description: The phasing out of preferential market arrangements with the advent of global trade liberalisation has led, in part, to a programme of Agricultural Diversification in the Caribbean, with a particular focus on the production of tropical fruits. It is envisaged that an increase in the production of tropical fruits, will not only better satisfy local consumption and tourism needs, but could also be used for export and processing. However, in order to realise these objectives, there is need for a great deal of research and development at the levels of both production and post-production. Modern Biotechnology provides the opportunity to carry out such research, not only in a shorter period of time, but in a more effective manner. The role of some of these new technologies viz. fermentation, plant cell and tissue culture, r-DNA, RFLP, RAPD, DNA-hybridization probes, monoclonal antibodies and anti-sense RNA in enhancing the production and post-harvest quality of fruits will be discussed. Whilst good scientific research is critical to the successful adoption of these technologies, adequate attention to the socio-economic, political and ethical issues is of equal importance.

description: We study spatial networks that are designed to distribute or collect a commodity, such as gas pipelines or train tracks. We focus on the cost of a network, as represented by the total length of all its edges, and its efficiency in terms of the directness of routes from point to point. Using data for several real-world examples, we find that distribution networks appear remarkably close to optimal where both these properties are concerned. We propose two models of network growth that offer explanations of how this situation might arise.

description: Mittels Fragebogen wurden über 100 Väter von Kindern mit Spracherwerbsschwierigkeiten über ihre Belastungen und Ressourcen, sowie über ihre eigenen Unterstützungsformen und Unterstützungs-wünsche befragt. Die Belastungen sind unterschiedlich. Während die einen Väter kaum belastende Momente mit ihrem Kind erleben, so sind für andere die Kommunikationsschwierigkeiten herausfordernd. Sorgen bereiten etlichen die Zukunftsperspektiven ihres Kindes und vor allem die Frage, ob sie ihr Kind genug fördern. Die meisten Väter fühlen sich ihren Kindern nahe, wobei sie zahlreiche Aktivitäten aufzählen, welche sie gerne mit ihnen ausüben. Diese bedeutsamen Aspekte können einerseits für die Bewältigung von belastenden Situationen andrerseits auch zur sprachlichen Förderung genutzt werden. Im heilpädagogischen Kontext sind diese Erkenntnisse für die Zusammenarbeit von Eltern und Fachpersonen relevant.

description: Probabilistic shaping for intensity modulation and direct detection (IM/DD) links is discussed and a peak power constraint determined by the limited modulation extinction ratio (ER) of optical modulators is introduced. The input distribution of 4-ary unipolar pulse amplitude modulation (PAM) symbols is optimized for short-reach transmission links without optical amplification nor in-line dispersion compensation. The resulting distribution is symmetric around its mean allowing to use probabilistic amplitude shaping (PAS) to generate symbols that are protected by forward error correction (FEC) and that have the optimal input distribution. The numerical analysis is confirmed experimentally for both an additive white Gaussian noise (AWGN) channel and a fiber channel, showing gains in transmission reach and transmission rate, as well as rate adaptability.

description: This article attempts to demonstrate how proximity to urban centers influences households' decision to allot their agricultural land to the production of either staple crops or high value cash crops. By applying fractional logit estimation technique on data collected from villages in Wollo of the Amhara Regional State in 2006, it has been found that proximity to urban centers, access to road, and education of the head of the household determine the crop choice in favor of the production of high value cash crops. While the purely liquid wealth positively affects the allocation of land for the production of cash crops, the direction of the impact of livestock on crop choice is found to depend on the particular location of the activities in relation to urban (market) centers. The pattern of crop choice has been translated into a variation in the level of per capita income across villages. Households operating in those villages located far from urban centers with no access to road are found to be the poorest among the villages covered by the study.

description: The Fortuin-Kasteleyn (FK) random cluster model, which can be exactly mapped from the $q$-state Potts spin model, is a correlated bond percolation model. By extensive Monte Carlo simulations, we study the FK bond representation of the critical Ising model ($q=2$) on a finite complete graph, i.e. the mean-field Ising model. We provide strong numerical evidence that the configuration space for $q=2$ contains an asymptotically vanishing sector in which quantities exhibit the same finite-size scaling as in the critical uncorrelated bond percolation ($q=1$) on the complete graph. Moreover, we observe that in the full configuration space, the power-law behaviour of the cluster-size distribution for the FK Ising clusters except the largest one is governed by a Fisher exponent taking the value for $q=1$ instead of $q=2$. This demonstrates the percolation effects in the FK Ising model on the complete graph.

description: This research examined how strongly appraisals can differentiate positive emotions and how they differentiate positive emotions. Thirteen positive emotions were examined, namely, amusement, awe, challenge, compassion, contentment, gratitude, hope, interest, joy, pride, relief, romantic love and serenity. Participants from Singapore and the USA recalled an experience of each emotion and thereafter rated their appraisals of the experience. In general, the appraisals accurately classified the positive emotions at rates above chance levels, and the appraisal–emotion relationships conformed to predictions. Also, the appraisals were largely judged by participants as relevant to their positive emotion experiences, and the appraisal–emotion relationships were largely consistent across the two countries.

description: The main Earth spheres interact with each other in various ways, attributed to the dynamic and complex nature of the Earth’s environment. For example, the interaction between the solar wind plasma and Earth’s magnetic field can cause phenomena in the atmosphere, such as auroras, geomagnetic storms, ionospheric disturbances, and other natural hazards. Previous studies used indices of solar wind plasma and geomagnetic fields in their ionospheric Total Electron Content (TEC) forecast models. However, the selected indices among the studies were inconsistent. Therefore, our study combines optimization Machine Learning (ML) techniques with statistical and hypothesis tests to determine features for ionospheric TEC forecast models. Together with three time-related parameters (Hour, Day of Year, and Year), 38 indices of solar activities and geomagnetic fields were tested to identify the best-suited parameters. Our investigation results reveal the Earth's Magnetosphere, Ionosphere, and Thermosphere (MIT) key parameters, including Plasma temperature (or Plasma speed), Proton density (or Flow pressure), Kp index (or ap, Dst index), F10.7 index, and Lyman alpha. Depending on specific processing strategies and computer capacity that can handle big data, more or less features can be included in mathematical models. Still, the essential parameters just mentioned should be prioritized. Using these MIT key parameters enables an optimization of both processing speed and accuracy in training the ML-based ionospheric forecast models.
