The illustrations and work of William Archer
Creators: name: Hansen, A
Publisher: name: University Of Tasmania
Year: 2023

description: In 2003 the Tasmanian Museum and Art Gallery (TMAG) received a donation of 33 botanical illustrations of Tasmanian native orchids from the Lorimer family. These illustrations created in the 1840s, 50s and 60s were by Tasmanian-born artist William Archer (1847-1874). Archer was prominent in many fields of early Tasmanian and Australian history. As a politician he was a member of Tasmania's first freely-elected Parliament. It is as an architect that Archer has been known in the past, designing some of Tasmania's landmark buildings. He was a member of arguably one of the greatest landholding dynasties in Tasmania. Archer's botanical as well as artistic input to what has been called the most important publication on Australian flora, Joseph Dalton Hooker's Flora Tasmaniae, has not been fully recognised to date. The thesis shows that Archer's contribution to the science of this book is not only worthy of his already recognised status as the first Australian born botanical artist, but that he should also be recognized as one of the great early pioneers of Australian botany and herbarium collectors. The thesis investigates the TMAG illustrations and a previously unpublished collection of a further 36 Archer orchid illustrations held by the Linnean Society in London. It compares them with the orchid plates in Flora Tasmaniae which were based on many of these illustrations. The thesis argues that the small changes made by Walter Hood Fitch (the lithographer) are in some cases significant and impact upon our understanding of the morphology of the plant. Archer went to England in 1857 to work with J D Hooker on Flora Tasmaniae. This thesis proves that Hooker acknowledged Archer's significant botanical contribution throughout the text of the publication, citing the many cases where it was Archer's advice and knowledge that he relied upon for the identification and classification of species. The thesis also shows that Archer had assembled a herbarium of great scientific importance that Hooker again relied upon, and that he allowed Archer access to the herbarium at Kew to add to his herbarium. This herbarium was eventually lost to Tasmania when it was purchased by Hooker after Archer's death and amalgamated it into the Kew Herbarium. Archer was a life member of the Linnean Society of London, and a Member of the Royal Society of Tasmania since 1847. He became Secretary of the Royal Society of Tasmania in 1861. He wrote and presented a number of scientific papers to the Society. Archer was the only Australian plant collector of Hooker's who went on to study and illustrate the specimens he was collecting instead of merely sending them to England for the English scientists to work on. The thesis acknowledges the other aspects of Archer's life, but is the first comprehensive study of Archer's role in nineteenth century Australian botany and botanical illustration.

description: Temperature changes at the Earth surface propagate into the subsurface and leave a thermal signature in the underlying soil and rock. Inversions of subsurface temperature measurements yield reconstructions of ground surface temperature (GST) histories that provide estimates of climatic changes. A question remaining in the interpretation of reconstructed GST histories is the extent to which GST changes reflect changes principally in surface air temperature (SAT), or whether other factors may be significant. Here we use a Land Surface Processes (LSP) model to examine the influence of precipitation changes on GST and subsurface temperature and moisture fields on annual to decadal timescales. We model soil and vegetation conditions representative of a prairie region in the southern Great Plains of North America and force the model with meteorological data synthesized from a typical year in the region. Model responses are observed after changes in the amount of daily precipitation, the intensity and frequency of daily precipitation, and the diurnal and seasonal timing of precipitation. We show that: (1) increasing daily precipitation cools mean annual GST, (2) increasing the intensity and reducing the frequency of daily precipitation, while holding the annual amount of precipitation constant, cools mean annual GST, and (3) shifting maximum precipitation to occur in the warmest months cools mean annual GST. We compare modeled results to observed precipitation changes during the 20th century and conclude that the observed precipitation changes would cause only small changes to GST within the modeled region, on the order of 0.1 K or less.

description: Paleomagnetic study of upper Cretaceous redbeds from two areas in South China was undertaken in an effort to constrain better the history of tectonic movements in southeastern Asia. From the Nanjing area (32°N, 119°E), high-temperature characteristic directions which pass a fold test were obtained from ten sites (43 samples) in the upper Cretaceous Puko and Yanzijing Formations. The paleomagnetic pole position (76.3°N, 172.6°E;A95 = 10.3°) agrees well with a late Cretaceous reference pole for Eurasia and thus confirms that this part of South China was fully sutured to Eurasia by the end of the Cretaceous with no paleomagnetically resolvable subsequent relative rotation. In western Sichuan (26.5°N, 102.3°E), high-temperature characteristic directions of normal and reverse polarity were obtained from twelve samples (48 specimens) in the upper Cretaceous to lower Paleocene Xiaoba and Leidashu Formations. A provisional paleomagnetic pole position (80.9°N, 296.8°E;A95 = 7.7°) differs significantly from a late Cretaceous Eurasia reference pole. In terms of apparent tectonic movement, the difference in paleopole positions would indicate a 13 ± 10.3° northward translation and 22 ± 11.2° counterclockwise rotation of western Sichuan relative to Eurasia. Confirmation of this reconnaisance result, which would suggest that western Sichuan was pushed ahead of an impinging India, is needed.

Characteristics of magnetic carriers responsible for Late Paleozoic remagnetization in carbonate strata of the mid-continent, U.S.A.

description: Magnetic analysis of carbonate strata of the mid-continent region of the United States indicates that the Late Paleozoic remagnetization already recognized in the Appalachians also affects almost the entire mid-continent. Magnetic intensity is regionally variable, with more intense magnetizations occurring on intracratonic arches. Magnetization is carried predominately by magnetite, which often occurs in tiny hollow spheroids composed of well formed octahedral microcrysts. Spheroid chemistry and morphology suggests that the magnetite is authigenic, composed of iron extracted from pre-existing pyrite or clay. The timing of the remagnetization, the character of the magnetite, and the regional variation in magnetic intensity support the idea that the remagnetization is a diagenetic consequence of tectonically-driven brine migration.

By extending the Lifshitz theory to treat chiral metamaterials, we find that a repulsive force and a minimum of the interaction energy exist for strong chirality, under realistic frequency dependencies and correct limiting values (for zero and infinite frequencies) of the permittivity, permeability, and chiral coefficients.

title: An Analysis of the Achievement Gains Made By Students in Ability-Grouped Vs. Random-Grouped Classroom Units
Creators: name: Ferrin, Luan H.
Publisher: name: Utah State University
Year: 1962

description: Because of the rapid advancements being made in the field of knowledge, educators, as well as those in other fields, must periodically take inventory. Current practices, policies, and methods must be carefully scrutinized to determine if they are the most effective. The group or class method of instruction is one such area.
The current philosophy of education held in many parts of the United States today places a great deal of importance upon the individual child. Numerous programs have been inaugurated to give the individual child as much attention as possible and still be able to have a class large enough to be practical financially. This task becomes increasingly difficult when the range of abilities within each classroom is so great. It isn't uncommon in the upper elementary and secondary classes to find a spread of from six to nine years difference in ability or achievement within one classroom.
Not only do we have the problem of range within the classroom, but with the increasing school population of today, classes have grown to a prohibitive size. Add these and other problems that stem from the pressures of present day society together, and even with the best possible teacher, we get only average results.
Synchrony between the Central Atlantic magmatic province and the Triassic-Jurassic mass-extinction event? Reply to Marzoli et al.

description: We are very pleased with the attention, long overdue, that the Triassic–Jurassic boundary and associated events, such as the CAMP, are receiving. This can only lead to greater specificity of hypotheses and greater understanding in the long run, and it is worth emphasizing some broad areas of agreement. Marzoli et al. (2008-this volume) points out the closeness in time of CAMP and Tr–J extinctions, and on this we all agree. We also agree that the systematic differences among different isotopic systems used for dating is a challenge to determining the relative timing of events dated with different techniques. This problem, however, seem to be fading as high-precision single-crystal U–Pb dates (206Pb/238U) are available from a variety of tuffs interbedded with marine strata as well as the North Mountain Basalt of Nova Scotia, which lies above the palynological Triassic–Jurassic extinction event in Nova Scotia. Schoene et al. (2006) obtained an age of 201.27 ± 0.03 Ma from this basalt, which is very close to an age of 201.5 Ma for a tuff 1 m above the last local occurrence of the topmost Triassic guide-fossil, the ammonite Choristoceras in a marine section in Peru (Schaltegger et al., 2007), presumably very close to the Triassic–Jurassic extinction event. Schaltegger et al. (2007) also obtained an age of 199.5 Ma for the Hettangian–Sinemurian boundary from the latter section. Consistent with these ages, Pálfy and Mundil (2006) obtained ages of 200.6 ± 0.3 Ma for an ash layer in ammonite-bearing Middle Hettangian marine sediments in, Alaska, and 198.0 ± 0.6 Ma for a tuff layer in Early Sinemurian sediments in Hungary. These dates are not compatible with the multi-crystal age for the Triassic–Jurassic boundary of 199.6 ± 0.3 Ma of Pálfy and Mundil (2006), a fact recognized by Pálfy and Mundil (2006). Thus, we are in complete agreement that the Triassic–Jurassic extinction event is extremely close in time to the onset of the CAMP. The question is, "are any of the known flows of the CAMP actually at or before this extinction event?". That is the key issue dealt with by Whiteside et al. (2007), and it is a possibility that we recognize as completely plausible, but not yet demonstrated. It is in that spirit of general agreement that we reply to Marzoli et al.'s, comment. We note, however, that their comment touches on far too many points to adequately address in this reply, and we chose to focus our response on their most substantive issues, recalling that our paper was focusing on the testable aspects of their overall hypothesis. We deal with their criticisms in the order they present them.
title: A Comparison of Aspiration Levels of Students in Ability-Grouped and Randomly-Grouped Schools
Creators: name: Jeffs, George Aaron
Publisher: name: Utah State University
Year: 1962

description: Grouping students with in the school setting has long been a concern to all those associated with the educative process. Much investigation has been devoted to the position of level of aspiration as influential motive forces for educational, occupational, and social achievement. Many avenues of grouping have been investigated and some very thoroughly. However, research concerning grouping in relation to level of aspiration in the school setting appears to be extremely limited. This study is designed to further investigate this issue. It might be said that this study consists of essentially two phases: (1) the development of instruments for measuring classroom aspiration, social aspiration, and educational aspiration; and (2) the determination of level of aspiration relationships which exist between junior high school boys grouped on the basis of ability and those randomly assigned to a classroom.
Early Record of Divisibility and Primality

description: We provide textual evidence on divisibility and primality in the ancient Vedic texts of India. Concern with divisibility becomes clear from the listing of all the fifteen pairs of divisors of the number 720. The total number of pairs of divisors of 10,800 is also given. The motivation behind finding the divisors was the theory that the number of divisors of a certain periodic process is related to the count associated with some other periodic process. For example, 720 (days and nights of the year) has 15 pairs of divisors, and this was related to the 15 days of the waxing and waning of the moon. Numbers that have no divisors appeared to have been used to symbolize the "transcendent" that is beyond periodicity and change.

description: We have produced thick-foil and fine-pitch gas electron multipliers (GEMs) using a laser etching technique. To improve production yield we have employed a new material, Liquid Crystal Polymer, instead of polyimide as an insulator layer. The effective gain of the thick-foil GEM with a hole pitch of 140 um, a hole diameter of 70 um, and a thickness of 100 um reached a value of 10^4 at an applied voltage of 720 V. The measured effective gain of the thick-foil and fine-pitch GEM (80 um pitch, 40 um diameter, and 100 um thick) was similar to that of the thick-foil GEM. The gain stability was measured for the thick-foil and fine-pitch GEM, showing no significant increase or decrease as a function of elapsed time from applying the high voltage. The gain stability over 3 h of operation was about 0.5%. Gain mapping across the GEM showed a good uniformity with a standard deviation of about 4%. The distribution of hole diameters across the GEM was homogeneous with a standard deviation of about 3%. There was no clear correlation between the gain and hole diameter maps.

New magnetostratigraphy for the Olduvai Subchron in the Koobi Fora Formation, northwest Kenya, with implications for early Homo

description: A problematic magnetostratigraphy for the Koobi Fora Formation has contributed to debates on the evolutionary implications for early hominin fossils. To address this, 50 independent samples distributed over a nearly 63-m-thick interval were collected from the lower-middle KBS Member type section in fossil collection Area 102, northeast Turkana Basin. Characteristic directions obtained by thermal demagnetization define a coherent magnetostratigraphy that is supported by alternating-field studies on 28 sister specimens and the prior tephrochronological framework. Two long polarity intervals were recognized, each 30–40 m in thickness, and interpreted as the upper part of the normal polarity Olduvai Subchron and the overlying reverse polarity Matuyama Chron. The end Olduvai consists of a normal–reverse–normal polarity sequence occurring over a thickness of at least 1 m but perhaps up to 5 m, suggesting that this subchron has a short reverse interval in its uppermost part. Such a fine-scale structure also has been reported from several other sites, like the Pliocene–Pleistocene boundary and point stratotype section at Vrica, Italy, which serves as a basis for formally delimiting three temporally discrete polarity subintervals for the Olduvai Subchron. These paleomagnetic results that place the upper boundary of the Olduvai at ∼ 48 m above the base of the KBS Member, coupled with published radioisotopic dates, firmly secure the age of partial cranium KNM-ER 3733 in the interval 1.78–1.48 Ma, with an interpolated age of ∼ 1.7 Ma, giving this fossil the most unambiguous numerical-age constraints, as compared to the oldest Homo cranial remains from Europe and Asia. Nonetheless, assured placement of the top of the Olduvai Subchron in the KBS Member is not sufficient in the face of other uncertainties to influence conventional interpretations of the timing and direction for the global dispersal of early Homo erectus.
Revealing the taboo : a theatrical investigation
Creators: name: Dobson, GP
Publisher: name: University Of Tasmania
Year: 2023

description: The project, Revealing the Taboo: A Theatrical Investigation, is a study into theatre that attempts to break down the barriers between open society and its regulatory alternative, the area of taboos. Initial motivations for the project were drawn from my experience as a playwright, exploring themes such as paedophilia and child abuse. My previous work prompted the question, 'If taboos are revealed from a perspective that attempts to challenge the social norm, how might that affect the sensitivities of an audience?' The exegesis (the theoretical component of the project) presents an extensive exploration of the relationships taboos have with contemporary theatrical presentation. Through the exegesis I establish a contemporary definition for taboo in relation to the theatre, differentiating it from current trends such as Aleks Sierz's In-Yer-Face' theatre. Set against the theatrical context, I also examine taboo as a current social norm, incorporating both the sanctions and penalties attracted by those who deviate from that norm. The exegesis supports the key focus of the project, the examination and creation of theatre that reveals taboo behaviour from a challenging perspective, in the process jeopardising the very concept of social norms. This style of theatre questions the status of certain taboos by reducing the degree of deviance associated with participation in taboo behaviour. The project identifies and presents a genre, Theatre of Taboos, and the exegesis examines the construction and effectiveness of this hypothesised genre. Three areas are particularly examined: firstly, taboos and incorporation of taboos in the theatre; secondly, cultural boundaries, limitations and restrictions ‚ÄövÑvÆ sanctions and penalties; and thirdly, the construction and sensitivities of the contemporary theatrical audience. The creative component of the project consists of a script presented through theatrical performance, these complementing and giving life to the notions set out in the theoretical investigation. The script, Ruled Lines, is an attempt to show a positive perspective of a taboo relationship between a teacher and their student, revealing taboos from a perspective that raises awareness of and challenges perceptions of what might constitute socially-condoned behaviour.

description: We report the electronic structure of the iron-chalcogenide superconductor, Fe1.04(Te0.66Se0.34), obtained with high resolution angle-resolved photoemission spectroscopy and density functional calculations. In photoemission measurements, various photon energies and polarizations are exploited to study the Fermi surface topology and symmetry properties of the bands. The measured band structure and their symmetry characters qualitatively agree with our density function theory calculations of Fe(Te0.66Se0.34), although the band structure is renormalized by about a factor of three. We find that the electronic structures of this iron-chalcogenides and the iron-pnictides have many aspects in common, however, significant differences exist near the Gamma-point. For Fe1.04(Te0.66Se0.34), there are clearly separated three bands with distinct even or odd symmetry that cross the Fermi energy (EF) near the zone center, which contribute to three hole-like Fermi surfaces. Especially, both experiments and calculations show a hole-like elliptical Fermi surface at the zone center. Moreover, no sign of spin density wave was observed in the electronic structure and susceptibility measurements of this compound.

description: If World War I has interested historians of the United States considerably less than other major wars, it is also true that children rank among the most neglected actors in the literature that exists on the topic. This essay challenges this limited understanding of the roles children and adolescents played in this transformative period by highlighting their importance in three different realms. It shows how childhood emerged as a contested resource in prewar debates over militarist versus pacifist education; examines the affective power of images of children—American as well as foreign—in U.S. wartime propaganda; and maps various social arenas in which the young engaged with the war on their own account. While constructions of childhood and youth as universally valid physical and developmental categories gained greater currency in the early twentieth century, investigations of young people in wartime reveal how much the realities of childhood and youth differed according to gender, class, race, region, and age.
The Paleomagnetic Field from Equatorial Deep-Sea Sediments: Axial Symmetry and Polarity Asymmetry

description: Paleomagnetic data from 89 equatorial deep-sea sediment cores indicate that the configuration of the time-averaged geomagnetic field depends strongly on polarity state but that it remains within 1 degree of axial symmetry throughout the Pliocene and Pleistocene (last 5 million years). The relative magnitude of the nondipole field was greater by almost a factor of 2 during reverse than during normal polarity intervals. These results thus support earlier suggestions that there may be a standing (nonreversing) component of the geomagnetic dynamo.

The Study of Nanoscopic Phase Separation in Lipid Mixtures using Small Angle Neutron Scattering

description: In biological membranes the lipid composition is extraordinarily complex, which provides proteins with the optimal lipid micro environment for physiological activity. The complexity of lipid composition and the consequences for biological systems has attracted significant interest in the past four decades, particularly in the realm of nanoscopic phase coexistence. Nanoscale phase separated domains in the plasma membrane are significant due to their critical roles in cell trafficking and signaling functionality. In this thesis, we chose to revisit a simple binary mixture of lipids (DPPC and DLPC), whose relevance persists since some biological systems can be relatively simple, composed of only a few different lipid species. Moreover, this system exhibits patterned phase separation at a macroscale similar to that of more complex lipid mixtures. Using calorimetry, densitometry and small angle neutron scattering (SANS) we were able to revisit the phase diagram for this system. The nanoscale domain structures on the vesicles captured by SANS were characterized using an ab-initio fitting program (MONSA). The analysis revealed that the molecular volumes of the lipids are not simply additive relative to their behavior in single lipid systems but depend on molecule-to-molecule packing interactions in the different domain regions that coexist in the membrane.

description: Increased intestinal permeability and inflammation, both fueled by dysbiosis, appear to contribute to rheumatoid arthritis (RA) pathogenesis. This single-center pilot study aimed to investigate zonulin, a marker of intestinal permeability, and calprotectin, a marker of intestinal inflammation, measured in serum and fecal samples of RA patients using commercially available kits. We also analyzed plasma lipopolysaccharide (LPS) levels, a marker of intestinal permeability and inflammation. Furthermore, univariate, and multivariate regression analyses were carried out to determine whether or not there were associations of zonulin and calprotectin with LPS, BMI, gender, age, RA-specific parameters, fiber intake, and short-chain fatty acids in the gut. Serum zonulin levels were more likely to be abnormal with a longer disease duration and fecal zonulin levels were inversely associated with age. A strong association between fecal and serum calprotectin and between fecal calprotectin and LPS were found in males, but not in females, independent of other biomarkers, suggesting that fecal calprotectin may be a more specific biomarker than serum calprotectin is of intestinal inflammation in RA. Since this was a proof-of-principle study without a healthy control group, further research is needed to validate fecal and serum zonulin as valid biomarkers of RA in comparison with other promising biomarkers.

description: The Triassic–Jurassic (T–J) mass-extinction event is marked by isotope anomalies in organic (δ13Corg) and carbonate carbon (δ13Ccarb) reservoirs. These have been attributed to a (rapid) 4-fold rise in pCO2 as a result of massive flood basalt volcanism and/or methane hydrate dissociation. Here we examine the response of marine photosynthetic phytoplankton to the proposed perturbation in the carbon cycle. Our high-resolution micropalaeontological analysis of T–J boundary beds at St Audrie's Bay in Somerset, UK, provides evidence for a bio-calcification crisis that is characterized by (1) extinction and malformation in calcareous nannoplankton and (2) contemporaneous blooms of organic-walled, green algal 'disaster' species which comprise in one case > 70% of the total palynomorph fraction. Blooms of prasinophytes and acritarchs occur at the onset and in association with a prominent negative shift in δ13Corg values close to the first appearance of the Early Jurassic ammonite Psiloceras planorbis. Across the same interval we obtained palaeotemperature and palaeosalinity estimates from oyster low-Mg calcite based on Mg/Ca, Sr/Ca and δ18O records. The results of our palynological and geochemical analyses strongly suggest that shallow marine basins in NW Europe during this period became salinity stratified, inducing anoxic conditions. The T–J boundary event shows similarities with the Permian–Triassic (P–T) mass-extinction event, which was also marked by extensive flood basalt volcanism, negative excursions in carbon isotope records, a bio-calcification crisis, the development of shallow-marine anoxia and mass abundances of acritarchs in the Early Triassic. This leads us to suggest that the proliferation of green algal phytoplankton may be symptomatic of elevated carbon dioxide levels in the atmosphere and oceans during mass-extinction events.

description: A model for explaining the differences in physical chemical properties of the caseins was proposed, and the results of the experiments supporting this model are presented. κ, αsl , β and whole-casein were shown to exhibit circular dichroic measurements typical of random coiled or denatured proteins, all being similar. Modification of the proteins with Na-tetrathionate, S-mercapto-succinic anhydride, reduction and esterification or changes in the solvent system with urea or polyethylenimine effected the spectra only slightly. Significant dichroic changes were observed when pH adjustments were made. The interaction of polyethylenimine or κ-casein with αsl produced interaction products which were detectable with a nuclear magnetic resonance spectrometer. The interaction of polyethylenimine and as αsl -casein were detected by electrophoresis, ultracentrifugation, light scattering, solubility and nuclear magnetic resonance. This interaction was dependent upon pH, concentration and amino nitrogen content. αsl and κ-caseins were observed to be heat labile while their interaction product was more stable than each individual casein. The results suggest that the interaction of αsl and κ-caseins is through carboxyl and amino electrostatic bonds, and that their association is purely random due to lack of stoichiometry in the molecules. The role of urea in the dissociation of caseins is the disruption of both ionic and hydrogen bonds.

description: Claw and leg lesions are frequently observed in finishing pigs and are likely to compromise their welfare. Providing softer than the usual concrete flooring may reduce both the frequency and severity of these lesions. Therefore, this study evaluated the influence of rubber mats and floor perforation in the lying area on claw and leg health of finishing pigs. A total of 240 Swiss Large White finishing pigs from on average 24.9 kg until 102.3 kg were used in four batches, with six groups of 10 animals per batch. The six experimental pens initially measured 1.85×3.55 m and were enlarged after 6 weeks to 1.85×5.25 m. In all pens, one third of the floor space was built as a defecating area consisting of a concrete floor with 15% perforation. The remaining two thirds of the pen were designed as a lying area whose floor quality differed between the pens. It either consisted of concrete elements or was covered with rubber mats, and perforation of both floor types was either 0%, 5% or 10%. All individuals were scored for claw and leg lesions at the beginning, in the middle and at the end of the 12-week fattening period. Lesions were summarised in scores based on the results of a principal component analysis. The influence on lesion scores of floor material, amount of perforation in the lying area, assessment time, and sex was examined using mixed-models. The total claw lesion score and the total limb lesion score as well as the claw angle increased from the beginning to the end of the fattening period. The values for both scores were slightly lower for animals kept on rubber mats compared with animals kept on concrete floor. There was no effect of the percentage of perforation on the examined outcome variables. In conclusion, our results indicate that rubber mats in the lying area bring about improvements in some aspects of claw and leg health in fattening pigs, whereas there is no effect of floor perforation.

description: We report Raman scattering data of single crystals of magnetite (Fe3O4) with Verwey transition temperatures (Tv) of 123 and 117K, respectively. Both single crystals reveal broad electronic background extending up to 900 wavenumbers (~110 meV). Redistribution of this background is observed when samples are cooled below Tv. In particular, spectra of the low temperature phase show diminished background below 300 wavenumbers followed by an enhancement of the electronic background between 300 and 400 wavenumbers. To enhance the effect of this background redistribution we divide the spectra just below the transition by the spectra just above the transition. A resultant broad peak-like feature is observed, centered at 370 wavenumbers (45 meV). The peak position of this feature does not scale with the transition temperature. We discuss two alternative assignments of this feature to a spin or charge gap in magnetite.

Widespread formation of cherts during the early Eocene climate optimum

Subjects: Paleoclimatology

description: Radiolarian cherts in the Tethyan realm of Jurassic age were recently interpreted as resulting from high biosiliceous productivity along upwelling zones in subequatorial paleolatitudes the locations of which were confirmed by revised paleomagnetic estimates. However, the widespread occurrence of cherts in the Eocene suggests that cherts may not always be reliable proxies of latitude and upwelling zones. In a new survey of the global spatio-temporal distribution of Cenozoic cherts in Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) sediment cores, we found that cherts occur most frequently in the Paleocene and early Eocene, with a peak in occurrences at ~50 Ma that is coincident with the time of highest bottom water temperatures of the early Eocene climatic optimum (EECO) when the global ocean was presumably characterized by reduced upwelling efficiency and biosiliceous productivity. Cherts occur less commonly during the subsequent Eocene global cooling trend. Primary paleoclimatic factors rather than secondary diagenetic processes seem therefore to control chert formation. This timing of peak Eocene chert occurrence, which is supported by detailed stratigraphic correlations, contradicts currently accepted models that involve an initial loading of large amounts of dissolved silica from enhanced weathering and/or volcanism in a supposedly sluggish ocean of the EECO, followed during the subsequent middle Eocene global cooling by more vigorous oceanic circulation and consequent upwelling that made this silica reservoir available for enhanced biosilicification, with the formation of chert as a result of biosilica transformation during diagenesis. Instead, we suggest that basin-basin fractionation by deep-sea circulation could have raised the concentration of EECO dissolved silica especially in the North Atlantic, where an alternative mode of silica burial involving widespread direct precipitation and/or absorption of silica by clay minerals could have been operative in order to maintain balance between silica input and output during the upwelling-deficient conditions of the EECO. Cherts may therefore not always be proxies of biosiliceous productivity associated with latitudinally focused upwelling zones.
He2+-He charge transfer collisions using a 27-state close-coupled calculation with a diabatic molecular basis

description: A comparative study of two earlier three-state and fifteen-state [Chaudhuri et al., Pramana- J. Phys., 43, 175 (1994); ibid., Phys. Rev. A, 52, 1137 (1995)] close-coupled treatments of He2+-He single and double charge transfer collisions is made in this paper with a larger, 27-state close-coupled calculation. The calculations have been done using the diabatic molecular basis set used in the earlier work extended by adding excited orbitals leading to higher excitation channels up to 3s and 3p. For such molecular basis functions that go to the correct separated-atom limits used in this work, the present results show that without the inclusion of the electron translation factors (ETFs) the quantitative cross-section calculations up to velocity ~1.1 a.u. (~30 keV/amu) are in good agreement with both experiment and other calculations. This suggests that if ETFs are properly incorporated into the charge transfer collision studies at low energies this diabatic molecular basis can be used for benchmark calculations. With the aid of the Wannier's picture of the ground state correlations, a combined detailed analysis and comparison has been carried out to find a connection with the dynamic two-electron correlation picture in charge transfer collision processes which involve sequential/simultaneous two-electron exchange. If ETFs are included, the model approach of the present work may open up opportunities to investigate dynamic two-electron correlation effect in charge transfer ion-atom collision processes with benchmark accuracy.

description: Abstract

The purpose of this study is to explore the potential of quantum algorithms in enhancing derivatives pricing models on the Multi Commodity Exchange of India (MCX), focusing on improving the accuracy, efficiency, and reliability of price discovery. By examining the applicability and challenges of quantum computing in a real-market environment, this research aims to contribute to the evolving field of quantum finance and its implications for complex financial instruments. This study employs a hybrid methodology that combines classical linear regression for price prediction and the Quantum Approximate Optimization Algorithm (QAOA) for parameter optimization to analyze commodity prices in the base metals market. The approach involves data collection and preprocessing of trading records, implementation of a linear regression model using scikit-learn, and optimization through QAOA using Qiskit, culminating in a comprehensive evaluation of model performance and integrated visualization of results. The analysis of trading data for base metals from January 3 and 4, 2022, reveals significant trading volume and values, with copper and nickel showing notable market activity. The Quantum Approximate Optimization Algorithm (QAOA) produced optimization parameters that highlight the complexity of accurately predicting market prices, resulting in a high-cost value of 144,460,619,823.28, indicating a considerable discrepancy between predicted and actual trading values. The study underscores the potential of quantum algorithms to enhance price discovery in commodity trading, although challenges remain in achieving precise price predictions due to inherent market complexities and fluctuations. The variations in trading activity across different commodities suggest that while quantum techniques may provide insights, their current application requires further refinement for practical use in real-time trading environments. This analysis is limited by the dataset's relatively short time frame and the number of trading records, which may not fully represent market dynamics over longer periods.
