Convolution Results with Subclasses of p-Valent Meromorphic Function Connected with q-Difference Operator

Applying the operator of q-difference, we examine the convolution properties of the subclasses MSζ,qr,p(A,B) and MKζ,qr,p(A,B) of p-valent meromorphic functions defined in the punctured open-unit disc. We derived specific inclusion features and coefficient estimates for functions that fall into these subclasses. Additionally, connections between the results presented here and those discovered in earlier papers are emphasized.

All Hands on Deck: Coordinated approaches to Indigenous early career development

The Developing Indigenous Early Career Researchers Project is a three-year longitudinal study funded by the Australian Research Council investigating the experiences and perspectives of Indigenous early career researchers working in universities across Australia. In an earlier paper we explored self-identified needs of Indigenous early career researchers regarding the development of sound research trajectories and careers in the academy (Locke et al., 2022). This paper takes a step further in investigating, who is responsible and should be held to account for supporting the development of these Indigenous early carer researchers. Data collected from across all three stages (2020, 2021 and 2022) of this project suggests that Indigenous early career researchers consider that all university staff, including themselves have certain responsibilities towards developing their academic career trajectories. Some Indigenous ECRs also pointed out the roles that external agencies such as government and funding bodies play in guiding institutions to value and promote the diversity and wealth of knowledge that Indigenous academics bring to the academy. This paper engages an Indigenist research approach and employs relatedness theory in advocating the development of policies and programs to support the career trajectories of Indigenous Early Career Researchers, from an Indigenous epistemological standpoint. To close, this paper posits that to achieve optimum outcomes for Indigenous ECR’s there needs to be systematic and coordinated institutional approaches to developing career trajectories that ameliorate challenges and barriers to Indigenous ECR career progression.

Carbon quantum dots in breast cancer modulate cellular migration via cytoskeletal and nuclear structure

Carbon nanomaterials have been widely applied for cutting edge therapeutic applications as they offer tunable physio-chemical properties with economic scale-up options. Nuclear delivery of cancer drugs has been of prime focus since it controls important cellular signaling functions leading to greater anti-cancer drug efficacies. Better cellular drug uptake per unit drug injection drastically reduces severe side-effects of cancer therapies. Similarly, carbon dots (CDs) uptaken by the nucleus can also be used to set-up cutting edge nano delivery systems. In an earlier paper, we showed the cellular uptake and plasma membrane impact of combustion generated yellow luminescing CDs produced by our group from fuel rich combustion reactors in a one-step tunable production. In this paper, we aim to specifically study the nucleus by establishing the uptake kinetics of these combustion-generated yellow luminescing CDs. At sub-lethal doses, after crossing the plasma membrane, they impact the actin and microtubule mesh, affecting cell adhesion and migration; enter nucleus by diffusion processes; modify the overall appearance of the nucleus in terms of morphology; and alter chromatin condensation. We thus establish how this one-step produced, cost and bulk production friendly carbon dots from fuel rich combustion flames can be innovatively repurposed as potential nano delivery agents in cancer cells.

Identifying Tools and Techniques for Picking out Cultural Bottlenecks: Another Crucial Component of the Symbiotic Approach to Socio-Cultural Change

This paper is built upon our earlier papers on the symbiotic approach to sociocultural change, and extends them meaningfully in new directions. This is done by proposing different types of tools and techniques that can be used in identifying cultural bottlenecks, and can therefore be used to usher in, or bring about a faster pace of sociocultural change. We therefore, aptly and appropriately begin this paper by carrying out a brief overview of our earlier papers on sociocultural change, and by briefly laying down their various concepts and postulates. Subsequently, and resultantly, various tools and techniques for identifying and overcoming cultural bottlenecks are also proposed. These include an alignment with a cultural taxonomy, a comparative method to compare cultures, a high low analysis of values, a root cause analysis of cultural performance, analysis of cultural orientations, an evaluation of cultural performance by laying down metric and measurements and analyzing the pace of sociocultural change, etc. We also briefly discuss ethnographic techniques that can be used to evaluate cultures, including long-term ethnography and the ethnography of enculturation. Likewise, social science research methods, and components of research design are reviewed, besides some other approaches to identifying and analyzing cultural bottlenecks. We hope and anticipate that this paper will become a useful cog in the machine to bring about faster sociocultural change, and will become an intrinsic part of our globalization of science movement as well.

ON THE BINARY SEQUENCE $(1,1,0,1,0^3,1,0^7,1,0^{15},\ldots )$

Abstract Let $\mathbb {F}$ be a field and $(s_0,\ldots ,s_{n-1})$ be a finite sequence of elements of $\mathbb {F}$ . In an earlier paper [G. H. Norton, ‘On the annihilator ideal of an inverse form’, J. Appl. Algebra Engrg. Comm. Comput.28 (2017), 31–78], we used the $\mathbb {F}[x,z]$ submodule $\mathbb {F}[x^{-1},z^{-1}]$ of Macaulay’s inverse system $\mathbb {F}[[x^{-1},z^{-1}]]$ (where z is our homogenising variable) to construct generating forms for the (homogeneous) annihilator ideal of $(s_0,\ldots ,s_{n-1})$ . We also gave an $\mathcal {O}(n^2)$ algorithm to compute a special pair of generating forms of such an annihilator ideal. Here we apply this approach to the sequence r of the title. We obtain special forms generating the annihilator ideal for $(r_0,\ldots ,r_{n-1})$ without polynomial multiplication or division, so that the algorithm becomes linear. In particular, we obtain its linear complexities. We also give additional applications of this approach.

Emphasizing “Integrationism” in Twenty-First Century Science: Another Useful Tool to Generate Better Scientific Paradigms Better Quality Science

The core objective of this paper is to emphasize the importance of “integrationism” as a core and a central method, and as a core philosophy of science, social sciences included, and one that can naturally and reliably be used to generate much better paradigms, better frameworks, and better concepts in science, and higher quality and higher order science as well. We also believe and propose that this technique become vital to scientific endeavour as a whole. In order to better perform the task of laying down the bare essentials of this paper, we review our earlier papers on scientific method of which there have indeed been many published over the last couple of years or so, including our much more recent paper on foundationalism. We also then go on to explain and elucidate why inductivism, including methodological inductivism and nomothetic approaches provide the epistemological basis for this paper, and stand us in very good stead. We also examine and explore other essential prerequisites of this approach including the need and necessity of dogma and ideology-free science, coherentism, reliabilism, internal and external validity, accuracy, rigour, precision, and also explain how this approach can be used to integrate and synthesize paradigms, frameworks, methods, and methodologies as well across a broad spectrum.

The Shifting and Permeable Boundaries of Auditing: Evidence from Early Australian Examination Papers

AbstractThe Colin Ferguson Oration is the address given to attendees at the annual Australia Accounting Hall of Fame dinner and presentation evening. It is an invited oration, whereby an eminent modern‐day leader addresses the audience on matters at the intersection of business, government and the academe as they relate to the rich history, the current state and/or the future direction of the accounting profession. The oration is named in honour of Professor Colin Ferguson (1949–2014). Colin was the key figure driving the inception of the Australian Accounting Hall of Fame. In a decorated academic career, he worked tirelessly for many years and with great distinction at the intersection of accounting thought and practice encompassing auditing, forensic accounting and accounting information systems, so it was only fitting that this oration is named in his honour. This year's oration was delivered by Brad Potter, an Associate Professor of Accounting and a Director of the Centre for Accounting and Industry Partnerships at the University of Melbourne. Brad's research and consulting experience encompasses financial accounting and disclosure for both private sector and public sector entities. In particular, he has successfully managed and coordinated research projects involving the Australian Accounting Standards Board, National Water Commission, CPA Australia, the Institute of Chartered Accountants, Australia, Royal Botanic Gardens and the Institute of Public Accountants (IPA). This year's oration uses a unique dataset to gain insights into the development of the auditing profession, a topic of interest to academe, practitioners and standard‐setters, and one that is eminently suitable for publication in the Australian Accounting Review.

Counting the coils in cylindrical helical compression springs: A clarification note

Despite an early paper by Vogt addressing the difference between free and active coils and between end and dead coils, current design recommendations for the coil count in cylindrical helical compression springs do not enter in such details. This results in underestimating the flexibility of the spring and overestimating its solid length. This technical note clarifies the meaning of the relevant coil numbers and provides formal relationships that help the designer improve the prediction of the spring rate and of the solid length. Though the analysis can be applied to any type of spring ends, it is particularly effective for the typical squared and ground end setup, which is most frequently encountered in practice.

Hypothesis, Paradigm, Framework and Concept Evaluation and Testing Across Space and Time: A Revalidation of our Concepts of “Aeternitism” and “Omnimodism”

This paper is linked to our papers or our earlier work on neo-centrism, hypothesis formulation, the sociological ninety ten rule, cross-cultural research design, and inductive approaches to hypothesis formulation, all of which have been published by us over the years. Therefore, all the relevant papers are suitably referenced in this paper, and brief summaries and overviews of them provided. This is done in the interests of coherence, internal consistency and clarity, so that readers can understand and comprehend the core concepts easily. To emphasize and to reiterate here, all our papers are interrelated in a continuous chain, none of our papers conflict with each other in any way, and to any degree. We believe that there are no internal contradictions amongst our wide gamut and array of papers that we have been publishing over the years, and no logical fallacies and inconsistencies as well whatsoever. All our papers are therefore interrelated and mutually interdependent in a plethora of different ways; however, this paper offers a fresh perspective and takes the concepts proposed in our earlier papers in an altogether new trajectory. This is done through the means and mechanism of hypothesis, paradigm, framework and concept evaluation and testing across space and time. Likewise, axioms, principles, entities and assumptions, are also evaluated, tested, and revalidated for this purpose. A revalidation of our concepts of “aeternitism” and “omnimodism” is also carried out as a part of this paper. This exercise is done in the interests of better science and better reliabilism; it is also a core component of our “Globalization of science” mission and movement.

Correction to: A note on properly discontinuous actions

We correct a mistake appearing in the earlier paper “A note on properly discontinuous actions.”

Climatology of Atmospheric Unstable Layers Revisited: A Corrigendum

Abstract We have published a recent paper on differences between temperature fluctuations of various vertical scales in raw and processed U.S. high vertical resolution radiosonde data (HVRRD). In that paper, we note that the small-scale temperature fluctuations in the raw U.S. HVRRD are significantly larger than those in the processed U.S. HVRRD and that those small-scale temperature fluctuations are much larger during daytime that during nighttime. We believe that this is due to the varying amount of solar radiation falling on the radiosonde temperature sensor as the radiosonde instrument swings and rotates. In light of these new results, we present revisions to some of our conclusions about the climatology of atmospheric unstable layers. When we repeat our calculations of atmospheric unstable layers using the processed U.S. HVRRD, we find the following. 1) The 0000/1200 UTC differences in unstable layer occurrences in the lower stratosphere that were noted in our earlier paper essentially disappear. 2) The “notch” in the deep tropics where there is a relative deficiency of thin unstable layers and a corresponding excess of thicker layers is still a feature when processed data are analyzed, but the daytime notch is less marked when the processed data were used. 3) The discontinuity in unstable layer occurrences, when there was a change in radiosonde instrumentation, is still present when processed data are analyzed, but is diminished from what it was when the raw data were analyzed. Significance Statement In a previous paper deriving the climatology of atmospheric unstable layers, we emphasized several findings. We reexamine three of the main points of that paper when processed U.S. high vertical resolution radiosonde data are analyzed instead of the raw data used in that previous paper. We find the 0000/1200 UTC differences virtually disappear in the new analysis. We find that the “notch” feature previously noted at Koror still exists, and we find that the discontinuity in unstable layers, when radiosonde instrumentation is changed, is diminished, but is still present in the new analysis.

COVID-19 Pandemic Effects on Angler Effort and a Brown Trout Population in a Driftless Area Stream in Southeast Minnesota

Abstract Early opinions of the COVID-19 pandemic included equivocal notions of whether the pandemic would result in more or less angler effort and harvest in recreational fisheries. Early papers also suggested using changes in angling license sales to infer changes in angler effort but expressed concern about adequate assessment of pandemic effects on fisheries because of interruptions to routine assessment programs. To assess pandemic effects on angler effort at a stream trout fishery, a trail camera was installed, immediately prior to implementation of a statewide stay-at-home order, at a representative stream trout angling site that is part of a long-term fish monitoring program. The trail camera was deployed through the trout harvest angling season from the peak pandemic year of 2020 through cessation of most restrictions in 2022. Statewide sales of angling licenses and trout stamps were assessed through this time to compare with angler effort measured with the trail camera. Annual trout population assessments were examined for pandemic effects in conjunction with angler effort. Anglers were present on 84% of days in 2020, 66% in 2021 and 69% in 2022. Following the pandemic peak of 603 angler-hours in 2020, angler-hours declined by -23% between 2020 and 2021, and by -16% between 2020 and 2022; whereas statewide sales of licenses and trout stamps only declined by -4% between 2020 and 2021 and -11% between 2020 and 2022, suggesting more angler pressure at the study site than could be inferred by changes in license or trout stamp sales. Higher pressure during the pandemic was due in part to more anglers younger than 20 years old. Despite higher angler pressure in 2020, there was no long-term effect on the Brown Trout population, as adult abundance in 2021 and 2022 exceeded abundance in every year from 2017 to 2020. These data add to a limited number of similar field-based pandemic studies coupling changes in angler use with fish population responses and should provide further insight into the broader assessment of COVID-19 pandemic effects.

Corrigendum to Centralizers of subsystems of fusion systems [J.~Group Theory 18 (2015), 393--405

Abstract We fill in a gap in the proof of Theorem A in our earlier paper [J. Semeraro, Centralizers of subsystems of fusion systems, J. Group Theory 18 (2015), 3, 393–405].

The mixture of microbial culture was evaluated against the VG2.The process involved standard, vehicle and control. The standard being Brand X disinfectant, control being Water and vehicle being ethanol. Test being the compound VG2 dissolved in ethanol, 20nmoles in strength and being evaluated.

Exponential stability of a non-uniform Euler-Bernoulli beam with axial force

The aim of this paper is to investigate the boundary stabilization of a non-uniform Euler-Bernoulli beam with axial force generated by the equation ρ(x)utt+(σ(x)uxx)xx−(q(x)ux)x=0 defined in (0,1)×(0,∞), where the coefficients ρ(x)>0, σ(x)>0, and q(x)≥0. By adopting a new technique based on a qualitative theory of fourth-order linear differential equations, we prove that the spectrum of the system operator is confined to the open left-half complex plane and that all the associated eigenvalues are geometrically simple. Using this result and the Riesz basis approach, we obtain the exponential stability and the optimal decay rate of the system. This study extends the earlier paper by B.-Z. Guo [SIAM J. Control Optim., 40 (2002), pp. 1905–1923], where no axial force acting on the system (i.e., q≡0).

Minimal and proximal examples of -stable and -approachable shift spaces

Abstract We study shift spaces over a finite alphabet that can be approximated by mixing shifts of finite type in the sense of (pseudo)metrics connected to Ornstein’s $\bar {d}$ metric ( $\bar {d}$ -approachable shift spaces). The class of $\bar {d}$ -approachable shifts can be considered as a topological analog of measure-theoretical Bernoulli systems. The notion of $\bar {d}$ -approachability, together with a closely connected notion of $\bar {d}$ -shadowing, was introduced by Konieczny, Kupsa, and Kwietniak [Ergod. Th. & Dynam. Sys.43(3) (2023), 943–970]. These notions were developed with the aim of significantly generalizing specification properties. Indeed, many popular variants of the specification property, including the classic one and the almost/weak specification property, ensure $\bar {d}$ -approachability and $\bar {d}$ -shadowing. Here, we study further properties and connections between $\bar {d}$ -shadowing and $\bar {d}$ -approachability. We prove that $\bar {d}$ -shadowing implies $\bar {d}$ -stability (a notion recently introduced by Tim Austin). We show that for surjective shift spaces with the $\bar {d}$ -shadowing property the Hausdorff pseudodistance ${\bar d}^{\mathrm {H}}$ between shift spaces induced by $\bar {d}$ is the same as the Hausdorff distance between their simplices of invariant measures with respect to the Hausdorff distance induced by Ornstein’s metric $\bar {d}$ between measures. We prove that without $\bar {d}$ -shadowing this need not to be true (it is known that the former distance always bounds the latter). We provide examples illustrating these results, including minimal examples and proximal examples of shift spaces with the $\bar {d}$ -shadowing property. The existence of such shift spaces was announced in the earlier paper mentioned above. It shows that $\bar {d}$ -shadowing indeed generalizes the specification property.

Solutions for a flame propagation model in porous media based on Hamiltonian and regular perturbation methods

This article extends the exploration of solutions to the issue of flame propagation driven by pressure and temperature in porous media that we introduced in earlier papers. We continue to consider a p-Laplacian type operator as a mathematical formalism to model slow and fast diffusion effects, that can be given in the non-homogeneous propagation of flames. In addition, we introduce a forced convection to model any possible induced flow in the porous media. We depart from previously known models to further substantiate our driving equations. From a mathematical standpoint, our goal is to deepen in the understanding of the general behavior of solutions via analyzing their regularity, boundedness, and uniqueness. We explore stationary solutions through a Hamiltonian approach and employ a regular perturbation method. Subsequently, nonstationary solutions are derived using a singular exponential scaling and, once more, a regular perturbation approach.

Mudfog: Crabbe and Dickens, and the View from the Marshes

Abstract: This paper asks about the relationship of Crabbe's poetry (and his life) to Dickens, and pursues an interest in the marshy and muddy landscapes of David Copperfield, Bleak House , and Great Expectations , with attention also to Little Dorrit . I am interested in Dickens's neologism "mudfog," and how this extends through his fiction; in this specific case looking at Orlick in Great Expectations . I read him as deriving from Crabbe's Peter Grimes, and as an incarnation of the oozy stagnancy of the marshes in the novel. Here I draw on Julia Kristeva and Georges Bataille on the abject and the formless as a way of conceptualizing what Orlick, one of Dickens's more surprising characters, might represent. The whole paper is a continuation of interests discussed in an earlier paper on "Mudfog" ( Dickens Quarterly , June 2024).

Slow-wave-enhanced on-chip Michelson interferometer sensor: erratum.

The device described in our earlier paper [Opt. Lett.48, 5968 (2023)10.1364/OL.500033] as a slow wave enhanced on-chip Michelson interferometer sensor is correctly designated as a slow wave enhanced on-chip loop terminated Mach-Zehnder interferometer sensor. In the earlier paper, we experimentally demonstrated slow wave enhanced phase and spectral sensitivity in asymmetric loop-terminated Mach-Zehnder interferometer (LT-MZI) sensors. Compared to Mach-Zehnder interferometers (MZI) that experimentally demonstrated a phase sensitivity 84,000 rad/RIU-cm, the reflected path enhancement of the optical path length coupled with slow light enhancement with photonic crystal waveguides in on-chip slow light loop-terminated Mach-Zehnder interferometer sensors resulted in experimentally demonstrated phase sensitivity 277,750 rad/RIU-cm with theoretical phase sensitivity as high as 461,810 rad/RIU-cm, at the same form factor as the MZI of identical interferometer arm lengths.

Play fairway analysis of geothermal resources across the state of Hawai‘i: 5. Slim hole drilling on Lāna‘i island

This paper builds on four earlier papers detailing the results of the Hawai‘i Play Fairway (PF) project's first two phases. In Phase 3 the project deepened a water well on the rim of the caldera of Lāna‘i Volcano to a maximum depth of just over 1 km. Due to funding constraints, the project deepened an already existing water well that was proximal to our area of highest resource probability within the caldera. Drilling preparation included: completion of an Environmental Assessment, lowering a camera down the well, deviation logging, coordinating site preparation, procure and shipping, and participating in multiple community meetings. Drilling occurred 24/7 the entire month of June 2019. The project deepened Lāna‘i Well 10 from 427 m to 1057 m, while collecting continuous core, and measured a roughly linear temperature gradient averaging 42 °C/km and a maximum bottom hole temperature of 66 °C. This gradient is more than twice the background for Hawai‘i and within a range of gradients measured in this depth range for some exploration wells within the volcanically active East Rift Zone of Kīlauea Volcano. Geothermal gradient determinations and computed chemical geothermometer temperatures indicate that accessible temperatures within Lāna‘i Well 10 are 130–200 °C between 2 and 3 km depth. This paper includes a summary of detailed core logging, which found pervasive hydrothermal alteration. We recommend drilling a slim hole within Lāna‘i's caldera to ∼2 km, where considerably higher temperatures may be encountered. The positive implications this project's results have for the island of O‘ahu are substantial. The shield stage of O‘ahu's volcanoes ended 1–2 Million years earlier, however O'ahu uses more electricity than the rest of the islands combined.
