Instrument characterisation for optical activity measurements in the non-paraxial regime
Creators: name: Stewart, Connor
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Optical activity provides essential information about the chirality of molecular structures in organic chemistry and has many applications in spectroscopy, crystallography and molecular biology. Collimated light has traditionally been used and its effect upon passing through these media is well understood. The plane of a linearly polarised beam rotates a constant amount independently of the incident polarisation. The angle of rotation depends entirely on the beam path, concentration and structure of chiral molecules. The behaviour of linearly polarised light in the non-paraxial regime could be different due to the possibility of it containing other components of polarisations. However, the helicity of the field remains preserved in a highly focused beam and recent studies link the helicity to the amount of optical rotation, suggesting that focused beams give rise to the same optical rotation as collimated ones. The aim of this thesis is to develop an experimental setup that accurately measures the optical activity of a focused beam through a chiral sample. It is already known that light has to be collected in the forward direction. Thus, our experimental setup has been characterised in such a configuration and the beam has been completely characterised over varying wavelengths and optical vortices. The optical activity of a collimated beam with a fixed wavelength was measured through increasing concentrations of maltose and sucrose through varying beam path lengths. The same measurements were done for the non-paraxial case where the beam is focused. Cuvettes with various thicknesses containing the samples were translated through the focus of the beam and the Stokes parameters of the beam were calculated as a function of distance. The azimuthal angle was found to be independent of such translations and showed the same optical rotation as the collimated case.
Relative projectivity and transferability for partial lattices

description: A partial lattice P is ideal-projective, with respect to a class C of lattices, if for every K $\in$ C and every homomorphism $ϕ$ of partial lattices from P to the ideal lattice of K, there are arbitrarily large choice functions f : P $\rightarrow$ K for $ϕ$ that are also homomorphisms of partial lattices. This extends the traditional concept of (sharp) transferability of a lattice with respect to C. We prove the following: (1) A finite lattice P, belonging to a variety V, is sharply transferable with respect to V iff it is projective with respect to V and weakly distributive lattice homomorphisms, iff it is ideal-projective with respect to V. (2) Every finite distributive lattice is sharply transferable with respect to the class R mod of all relatively complemented modular lattices. (3) The gluing D 4 of two squares, the top of one being identified with the bottom of the other one, is sharply transferable with respect to a variety V iff V is contained in the variety M$ω$ generated by all lattices of length 2. (4) D 4 is projective, but not ideal-projective, with respect to R mod. (5) D 4 is transferable, but not sharply transferable, with respect to the variety M of all modular lattices. This solves a 1978 problem of G. Grätzer. (6) We construct a modular lattice whose canonical embedding into its ideal lattice is not pure. This solves a 1974 problem of E. Nelson.

How Much Spectrum is Too Much in Millimeter Wave Wireless Access

Year: 2017

subject: FOS: Computer and information sciences

description: A great increase in wireless access rates might be attainable by using the large amount of spectrum available in the millimeter wave (mmWave, 30 - 300 GHz) band. However, due to higher propagation losses inherent in these frequencies, to use wider bandwidth for transmission at ranges beyond 100 meters or in non-line-of-sight (NLOS) settings may be ineffective or even counterproductive when the penalty for estimating the channel is taken into account. In this work we quantify the maximum beneficial bandwidth for mmWave transmission in some typical deployment scenarios which use pilot-based channel estimation and assume a minimum mean square error (MMSE) channel estimator at the receiver. We find that for an I.I.D. block fading model with coherence time $T_c$ and coherence bandwidth $B_c$, for transmitters and receivers equipped with a single antenna, the optimal (rate-maximizing) signal-to-noise-ratio is a constant that only depends on the product $B_cT_c$, which measures the channel coherence and equals the average number of orthogonal symbols per each independent channel coefficient. That is, for fixed channel coherence, the optimal bandwidth scales linearly with the received signal power. Under some typical deployment scenarios with both transmit and receive side beamforming, 1 GHz bandwidth can be too much.

Exploring the actions of citizens as scientists through experimentation with aquaponics

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Scientists are increasingly collaborating with citizens to engage in science where, on their own, they lack the resources to collect or analyse the data. In most of these collaborative projects, citizens can be classified as science assistants, helping scientists in their endeavours. While this can produce significant benefits for both the citizen and the scientist, the question arises as to the extent that citizens can contribute to all aspects of the scientific process. This thesis explores how citizens contribute to scientific discovery by experimenting at home in aquaponics systems. Aquaponics allows fish and plants to be grown together providing fresh, locally grown vegetables and fish to homes and communities. Despite the core principles being well known, most systems are independently designed by individuals and show high levels of innovation. There is significant scope for learning how system design, location and other factors affect the success of these systems. The question arises as to whether these innovators are able to join together to research this area by providing detailed on-line data that tracks their system progress as well as analysing the collected dataset, proposing hypotheses, and resolving them based on the available data. From an aquaponics point of view, this was the first systematic study of how home based systems, which comprise of 86% of all aquaponics systems, performed, informs the home aquaponics industry and provides data for future analysis. From a citizen science point of view, this study investigates the key question as to how citizens contributed to science. The ways the citizens research was compared and contrasted with the way scientists researched in the field of aquaponics, providing insights into areas that need further consideration when endeavouring to involve citizens in all aspects of scientific research.

description: We present the results of a seven-year-long radial velocity survey of a sample of 88 main-sequence and evolved stars to reveal signatures of Jupiter-mass planets in the solar-age and solar-metallicity open cluster M67. We aim at studying the frequency of giant planets in this cluster with respect to the field stars. In addition, our sample is also ideal to perform a long-term study to compare the chemical composition of stars with and without giant planets in detail. We analyzed precise radial velocity (RV) measurements obtained with five different instruments. We conducted Monte Carlo simulations to estimate the occurrence rate of giant planets in our radial velocity survey. All the planets previously announced in this RV campaign with their properties are summarized here: 3 hot Jupiters around the main-sequence stars YBP1194, YBP1514, and YBP401, and 1 giant planet around the evolved star S364. Two additional planet candidates around the stars YBP778 and S978 are also analyzed in the present work. We discuss stars that exhibit large RV variability or trends individually. For 2 additional stars, long-term trends are compatible with new binary candidates or substellar objects, which increases the total number of binary candidates detected in our campaign to 14. Based on the Doppler-detected planets discovered in this survey, we find an occurrence of giant planets of ~18.0%(+12.0/-8.0%) in the selected period-mass range. This frequency is slightly higher but consistent within the errors with the estimate for the field stars, which leads to the general conclusion that open cluster and field statistics agree. However, we find that the rate of hot Jupiters in the cluster (~5.7%(+5.5/-3.0%)) is substantially higher than in the field.

An interdisciplinary analysis of the effect of an assertive intervention on situational writing apprehension in practitioners of professional writing
Creators: name: Larsson, Britt
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: The aims of this project were to identify the causes of situational writing apprehension (Daly & Hailey, 1984) in the sample, to test the effectiveness of an assertive intervention in addressing them, and to analyze these causal factors and intervention effects in terms of the discourse communities represented in the research site. Situational writing apprehension (SWA) refers to situationally-induced anxiety which affects individuals' writing processes and the texts which they produce. The problem was formulated as one polarity of the writing apprehension construct (Daly & Miller, 1975) and originally researched in the discipline of psychology. However because of the diversity and discursive complexity of writing sites, SWA has not attracted subsequent research interest. The study addresses this research gap through an interdisciplinary approach (Watson & Gallois, 2002; Wetherell, 1996) which encompasses social psychological approaches and the more sociological/ anthropological and social interactional approaches to professional discourse analysis. The project consists of two intervention studies carried out in an action research framework in the public relations (PR) industry: a collective case study of 15 PR consultants and a quasi-experiment employing 52 PR consultants from diverse PR sites. In the exploratory phase of the studies an empirically based analysis was undertaken of the way participants constructed the problem. In the intervention phase, the treatment was developed to address the causal factors which had been identified. Mixed data sets provide evidence that: (1) SWA was largely caused by power imbalances in the structure of social relations in the site and to a lesser extent by motivational, environmental and writing process factors; and (2) the problem may be reduced by an assertive intervention delivered in the context of an action-research based professional writing training program. By being situated in an organizational site defined by professional discourse, this research makes a theoretical and empirical contribution to the field of professional discourse analysis. By identifying practices which constrain the production of professional texts and practices which offer affordances to it, its findings may also provide guidance for practitioners of professional discourse in addressing their writing goals. From a research perspective, it provides an example of empirically grounded interdisciplinary writing research informed by a critical pragmatic approach that may be relevant to professional, and pedagogical concerns.

description: Recently it has been shown that the vacuum state in QED is infinitely degenerate. Moreover a transition among the degenerate vacua is induced in any nontrivial scattering process and determined from the associated soft factor. Conventional computations of scattering amplitudes in QED do not account for this vacuum degeneracy and therefore always give zero. This vanishing of all conventional QED amplitudes is usually attributed to infrared divergences. Here we show that if these vacuum transitions are properly accounted for, the resulting amplitudes are nonzero and infrared finite. Our construction of finite amplitudes is mathematically equivalent to, and amounts to a physical reinterpretation of, the 1970 construction of Faddeev and Kulish.

description: The temporary resistance triggered by phase slip will result in the switching of superconductor nanowire to a permanent normal state, decreasing the switching current. In this letter, we propose an improved impedance matching circuit that releases the transition triggered by phase slips to the load resistor through the RF port of a bias tee. The transportation properties with different load resistors indicate that the switching current decreases due to the reflection caused by impedance mismatching, and is maximized by optimized impedance matching. Compared to the same setup without impedance matching circuit, the switching current was increased from 8.0 micro A to 12.2 micro A in a niobium nitride nanowire after releasing the temporary transition triggered by phase slips. The leakage process with impedance matching outputs a voltage pulse which enables the user to directly register the transition triggered by phase slips. The technique for maximizing the switching current has potential practical application in superconductor devices, and the technique for counting phase slips may be applied to explore the quantum behavior of phase slips.

description: Multiphase Co-35Ni-20Mo-10Cr alloy MP35N is a high strength alloy with excellent corrosion resistance. Its applications span chemical, medical, and food processing industries. Thanks to its high modulus and high strength, it found applications in reinforcement of ultra-high field pulsed magnets. Recently, it has also been considered for reinforcement in superconducting wires used in ultra-high field superconducting magnets. For these applications, accurate measurement of its physical properties at cryogenic temperatures is very important. In this paper, physical properties including electrical resistivity, specific heat, thermal conductivity, and magnetization of as-received and aged samples are measured from 2 to 300 K. The electrical resistivity of the aged sample is slightly higher than the as-received sample, both showing a weak linear temperature dependence in the entire range of 2 - 300 K. The measured specific heat Cp of 0.43 J/g-K at 295 K agrees with a theoretical prediction, but is significantly smaller than the values in the literature. The thermal conductivity between 2 and 300 K is in good agreement with the literature which is only available above 77 K. Magnetic property of MP35N changes significantly with aging. The as-received sample exhibits Curie paramagnetism with a Curie constant C = 0.175 K. While the aged sample contains small amounts of a ferromagnetic phase even at room temperature. The measured MP35N properties will be useful for the engineering design of pulsed magnets and superconducting magnets using MP35N as reinforcement.

description: We develop a scheme for deterministic generation of an entangled state between two atoms on different Rydberg states via a chirped adiabatic passage, which directly connects the initial ground and target entangled states and also does not request the normally needed blockade effect. The occupancy of intermediate states suffers from a strong reduction via two pulses with proper time-dependent detunings and the electromagnetically induced transparency condition. By solving the analytical expressions of eigenvalues and eigenstates of a two-atom system, we investigate the optimal parameters for guaranteeing the adiabatic condition. We present a detailed study for the effect of pulse duration, changing rate, different Rydberg interactions on the fidelity of the prepared entangled state with experimentally feasible parameters, which reveals a good agreement between the analytic and full numerical results.

Using a Gross-Pitaevskii approach and a mean field Gutzwiller variational method, we explore both the weakly interacting and strongly interacting regime, respectively. We calculate the boundaries between the density-wave/supersolid and the Mott-insulator/superfluid phases as a function of magnetic flux and uncover regions of supersolidity. The mean-field results are confirmed by numerical simulations using a cluster mean field approach.

Movement, vertebral morphology and age dynamics of the common sawshark Pristiophorus cirratus

Subjects: Other education not elsewhere classified

description: The common sawshark (Pristiophorus cirratus) is a deepsea shark endemic to southeastern Australia that has been fished for over 90 years. We explored two critical parameters required for effective fisheries management: movement ecology and longevity. To investigate movement ecology, three common sawsharks were tagged with passive satellite archival tags (PSATs) off the northeast coast of Tasmania in 2016. Archived data suggest sawsharks are able to move larger distances than previously thought and engage in vertical movements with a diel pattern observed. To gain insight into the longevity of sawsharks, we first assessed their vertebral morphology to best direct age determination efforts for vertebral band pair analysis. Vertebrae located in the post-branchial region were found to be the largest and least variable throughout ontogeny and therefore most ideal for band pair analysis. A range of age determination methodologies, traditional and non-traditional, were then applied to shark vertebrae to test the efficacy of vertebral band-pair analysis in sawsharks. Bands were indeterminable across all methodologies. This study provides insights into population dynamics and vertebral morphometrics and offers direction for future age determination studies in sawsharks. Such information will provide vital information for the conservation and management of this data-poor species.

description: We analysed new wide-field, wide- and narrow-band optical images of IC 59 and IC 63, two nebulae which are externally illuminated by the early B-star γ Cas, with the objective of mapping the extended red emission (ERE), a dust-related photoluminescence process that is still poorly understood, in these two clouds. The spatial distribution of the ERE relative to the direction of the incident radiation and relative to other emission processes, whose carriers and excitation requirements are known, provides important constraints on the excitation of the ERE. In both nebulae, we find the ERE intensity to peak spatially well before the more extended distribution of mid-infrared emission in the unidentified infrared bands, supporting earlier findings that point toward far-ultraviolet (11 eV < E$_\mathrm{photon}$ < 13.6 eV) photons as the source of ERE excitation. The band-integrated absolute intensities of the ERE in IC 59 and IC 63 measured relative to the number density of photons available for ERE excitation are lower by about two orders of magnitude compared to ERE intensities observed in the high-latitude diffuse interstellar medium (ISM). This suggests that the lifetime of the ERE carriers is significantly reduced in the more intense radiation field prevailing in IC 59 and IC 63, pointing toward potential carriers that are only marginally stable against photo-processing under interstellar conditions. A model involving isolated molecules or molecular ions, capable of inverse internal conversion and recurrent fluorescence, appears to provide the most likely explanation for our observational results.

A study of vocabulary knowledge and vocabulary learning strategies of Chinese EFL learners

Subjects: Other education not elsewhere classified

description: Previous studies on vocabulary knowledge (VK) have primarily focused on EFL learners' vocabulary learning strategies (VLSs) in relation to their breadth of VK. However, the relationship between VLSs and the depth of VK has as yet been underexplored. This study sets out to examine how Chinese EFL learners' gender, discipline, proficiency levels and VLSs might contribute to their depth, as well as their breadth of VK. A number of 419 Chinese EFL students from four universities in Mainland China took the Vocabulary Size Test (VST), and Word Associates Test (WAT), completed a VLS questionnaire, and wrote an English essay. The two vocabulary tests and the essay were adopted to assess the participants’ breadth and depth of vocabulary knowledge respectively. Follow-up semi-structured interviews were conducted to seek any possible convergence and corroboration with the results drawn on the analyses of the quantitative data, or to shed more light on some of the quantitative findings where such convergence is not found. My findings showed that firstly the participants’ depth of VK measured by WAT was less satisfactory in comparison to their breadth of VK measured by VST. Secondly, the participants used less frequent and less familiar words in their writings and they seem not good at using various words or phrases to express meaning. Thirdly, the participants favored repetition strategies, inferencing strategies and using dictionaries, but disfavored notetaking strategies, production-based strategies and association and imagination strategies. Fourthly, inferencing strategies made a significant and positive contribution to participants’ breadth and depth of VK (VST and WAT) and productive lexical diversity, whereas repetition and social strategies made a significant but negative contribution to their breadth of VK. Self-initiated strategies significantly and positively correlated with some aspects of participants’ productive VK. Finally, the overall variables (i.e. gender, discipline, proficiency levels, and VLSs) explained 13.2% of the variance in participants’ breadth of VK (VST) and 13.7% of the variance in their depth of VK (WAT) while these variables explained less variance in participants’ productive VK. This study may inform curriculum developers and shed light on both vocabulary teaching and learning.

description: We deposit intrinsic hydrogenated amorphous silicon (a-Si:H) thin films by reactive pulsed laser deposition, for various hydrogen pressures in the 0-20 Pa range, at a low deposition temperature of 120C, and investigate the hydrogen incorporation, structural, optical, and electrical properties of the films, as a function of the ambient hydrogen pressure. The film thickness decreases linearly as the hydrogen pressure increases. The hydrogen content of the films is determined by infrared spectroscopy and the optical bandgap from UV-Vis-NIR transmittance and reflectance measurements. Electric measurements yield the dark conductivity of the films. The hydrogen concentration of the films lies in the 10^21-10^22 cm^(-3) range and increases with the hydrogen pressure until the latter reaches 15 Pa, beyond which the hydrogen concentration decreases. The optical bandgap and dark conductivity follow the hydrogen concentration variation of the films. The dark conductivity lies in the 10^(-9)-10^(-10) S/cm range. An unusually wide optical bandgap of 2.2-2.6 eV is observed.

description: The concept of software quality is very complex and has many facets. Reflecting all these facets and at the same time measuring everything related to these facets results in comprehensive but large quality models and extensive measurements. In contrast, there are also many smaller, focused quality models claiming to evaluate quality with few measures. We investigate if and to what extent it is possible to build a focused quality model with similar evaluation results as a comprehensive quality model but with far less measures needed to be collected and, hence, reduced effort. We make quality evaluations with the comprehensive Quamoco base quality model and build focused quality models based on the same set of measures and data from over 2,000 open source systems. We analyse the ability of the focused model to predict the results of the Quamoco model by comparing them with a random predictor as a baseline. We calculate the standardised accuracy measure SA and effect sizes. We found that for the Quamoco model and its 378 automatically collected measures, we can build a focused model with only 10 measures but an accuracy of 61% and a medium to high effect size. We conclude that we can build focused quality models to get an impression of a system's quality similar to comprehensive models. However, when including manually collected measures, the accuracy of the models stayed below 50%. Hence, manual measures seem to have a high impact and should therefore not be ignored in a focused model.

description: Distribution of eQTL-SNPs along pig autosomal chromosomes. The histograms represent the distribution of eQTL-SNPs along chromosomes, with each bar corresponding to a 5-Mb segment. The density of eQTL-SNPs is represented by a color gradient from green to red. The scale for the eQTL-SNP count is on the Y-axis and varies among chromosomes. On SSC7, the region between 20 Mb and 30 Mb that has a high density of eQTL-SNPs overlaps the MHC locus. (PDF 30 kb)

description: We report evidence for a reentrant spin glass phase in electron-doped $\text{EuFe}_2\text{As}_2$ single crystals and first traces of the superconductivity re-entrance in optics. In the close-to-optimal doped $\text{Eu}(\text{Fe}_{0.91}\text{Ir}_{0.09})_2\text{As}_2$ and $\text{Eu}(\text{Fe}_{0.93}\text{Rh}_{0.07})_2\text{As}_2$ samples two magnetic transitions are observed below the superconducting critical temperature $T_c \approx 21$~K: the canted $A$-type antiferromagnetic order of the $\text{Eu}^{2+}$ ions sets in around $17\,\text{K}$; the spin glass behavior occurs another $2\,\text{K}$ lower in temperature. In addition, strong evidence for an additional transition is found far below the spin glass temperature. Our extensive optical and magnetic investigations provide new insight into the interplay of local magnetism and superconductivity in these systems and elucidate the effect of the spin-glass phase on the reentrant superconducting state.

description: A multi-channel algebraic scattering (MCAS) method has been used to solve coupled sets of Lippmann-Schwinger equations for the $α$+${}^6$He cluster system, so finding a model spectrum for ${}^{10}$Be to more than 10 MeV excitation. Three states of ${}^6$He are included and the resonance character of the two excited states taken into account in finding solutions. A model Hamiltonian has been found that gives very good agreement with the known bound states and with some low-lying resonances of ${}^{10}$Be. More resonance states are predicted than have as yet been observed. The method also yields $S$-matrices which we have used to evaluate low-energy ${}^6$He-$α$ scattering cross sections. Reasonable reproduction of low-energy differential cross sections and of energy variation of cross sections measured at fixed scattering angles is found.

Investigating communities of practice and ELT teacher research in Cambodia

description: This thesis is a qualitative study of English Language Teaching (ELT) research at tertiary-level in contemporary Cambodia. It comprises two phases. Phase 1 explores various views of ELT teacher research provided in a focus group discussion and two individual interviews by six Cambodian teachers representing different ELT institutions in Phnom Penh, the Cambodian capital. Phase 2 investigates teachers‟ actual research activities through an ethnographically-informed case study, and the research engagement at different levels (macro, meso, and micro) in the context of the CamTESOL conference series. The study reveals that Cambodian ELT teachers hold unclear and confused conceptions of "teacher research‟ and "research‟ and this leads to difficulties in operationalising and carrying out research projects. This issue is compounded by the power of the CamTESOL conference series which has created a demand for research presentations, regardless of the underlying quality of the research, and established a research rhythm which has come to regulate the research timelines of most Cambodian ELT researchers‟ research engagement in their actual research projects. A consequence is that much of the research undertaken by Cambodian ELT teacher researchers lacks rigor and displays serious research shortcomings. The study also reveals that there were no true communities of practice functioning in the research practices of CamTESOL or individual ELT institutions in Cambodia. However, the research practices among individual ELT teachers come close to operating as a true community of practice. The study calls for reconceptualising "ELT teacher research‟ in Cambodia and adopting appropriate, workable operational mechanisms, i.e. a suitable modeling of a community of practice, for enhancing ELT teacher research practices there. The implications of ELT teacher research in the Cambodian setting are also of relevance to the development of ELT teacher research in other countries in the Southeast Asian region and beyond.

description: Background: Following the ban on antimicrobial usage for growth promotion in animal husbandry in the EU, nonantimicrobial agents including heavy metal ions (e.g. zinc and copper), prebiotics or probiotics have been suggested as alternatives. Zinc has extensively been used in pig farming, particularly during weaning of piglets to improve animal health and growth rates. Recent studies, however, have suggested that high dietary zinc feeding during weaning of piglets increases the proportion of multi-drug resistant E. coli in the gut, contraindicating the appropriateness of zinc as an alternative. The underlying mechanisms of zinc effects on resistant bacteria remains unclear, but coselection processes could be involved. In this study, we determined whether E. coli isolates from intestinal contents of piglets that had been supplemented with high concentrations of zinc acquired a higher tolerance towards zinc, and whether multi-drug resistant isolates tolerated higher zinc concentrations. In addition, we compared phenotypic zinc and copper resistance of E. coli isolates for possible correlation between phenotypic resistance/tolerance to different bivalent ionic metals. Results: We screened phenotypic zinc/copper tolerance of 210 isolates (including antimicrobial resistant, multi-drug resistant, and non-resistant E. coli) selected from two, independent zinc-feeding animal trials by determining a zinc/ copper minimal inhibitory concentration (Merlin, Bornheim-Hersel, Germany). In both trials, groups of piglets were supplemented either with high dietary zinc (> 2000 ppm) or control (50–70 ppm, background) concentrations. Our observations showed that high concentration zinc exposure did not have an effect on either zinc or copper phenotypic tolerance of E. coli isolates from the animals. No significant association was found between antimicrobial resistance and phenotypic zinc/copper tolerance of the same isolates. Conclusion: Our findings argue against a co-selection mechanism of antimicrobial drug-resistance and zinc tolerance after dietary zinc supplementation in weaning piglets. An explanation for an increase in multi-drug resistant isolates from piglets with high zinc dietary feeding could be that resistant bacteria to antimicrobial agents are more persistent to stresses such as zinc or copper exposure.

description: Big Bang nucleosynthesis (BBN) theory predicts the abundances of the light elements D, $^3$He, $^4$He and $^7$Li produced in the early universe. The primordial abundances of D and $^4$He inferred from observational data are in good agreement with predictions, however, the BBN theory overestimates the primordial $^7$Li abundance by about a factor of three. This is the so-called "cosmological lithium problem". Solutions to this problem using conventional astrophysics and nuclear physics have not been successful over the past few decades, probably indicating the presence of new physics during the era of BBN. We have investigated the impact on BBN predictions of adopting a generalized distribution to describe the velocities of nucleons in the framework of Tsallis non-extensive statistics. This generalized velocity distribution is characterized by a parameter $q$, and reduces to the usually assumed Maxwell-Boltzmann distribution for $q$ = 1. We find excellent agreement between predicted and observed primordial abundances of D, $^4$He and $^7$Li for $1.069\leq q \leq 1.082$, suggesting a possible new solution to the cosmological lithium problem.
