ABSTRACTSir Ernest Shackleton's Imperial Trans-Antarctic Expedition famously did not succeed in traversing the Antarctic continent from the Weddell Sea to the Ross Sea. It was, nevertheless, an enterprise that engaged the interest of New Zealanders and the rest of the British Empire even as World War I was being fought. When one of the expedition ships, Aurora, broke from her moorings soon after arrival in McMurdo Sound and drifted trapped in pack ice for months, the construction of a temporary jury rudder while still at sea enabled her crew to make their way to Port Chalmers, Dunedin for more extensive repairs in 1916. This paper discusses interactions between the Otago Museum staff and the crew of Aurora while she was in port, the offer of the replaced jury rudder to the museum, and reflects on the concerns and interests that might have contributed to the offer and its rejection.

AbstractIn the austral summer 1986–87, the 75th anniversary of Amundsen's conquest of the South Pole, a sledging party of four from a private expedition, 90° South, set out to retrace his route. This was the culmination of five years of preparations, in which sufficient international support was raised to enable the expedition to reach Antarctica and operate independently, using its own ship, MV Aurora… The expedition's Twin Otter aircraft, flying from New Zealand, staged a unique refuelling operation on an iceberg within the pack ice 160 km from the Balleny Islands. Establishing a temporary base at Bay of Whales, Ross Ice Shelf, on 5 December 1986, the expedition used its aircraft to set up supply depots 220 km apart along the route to the pole. The sledging party with two teams of Greenland huskies crossed the ice shelf and ascended the Axel Heiberg Glacier to the polar plateau, reaching their fourth depot in 86°S in late January. Some 400 km short of the Pole, lack of time compelled the party to return to rendezvous with the ship. Glaciological investigations included the formation of icebergs from the Ross Ice Shelf, and collection of ground truth data to help in evaluating remote sensing data. The team also set up a commemorative plaque close to Amundsen' s cairn on Mount Betty.

Abstract The design and operation of a Thin-Cloud Rotating Shadowband Radiometer (TCRSR) described here was used to measure the radiative intensity of the solar aureole and enable the simultaneous retrieval of cloud optical depth, drop effective radius, and liquid water path. The instrument consists of photodiode sensors positioned beneath two narrow metal bands that occult the sun by moving alternately from horizon to horizon. Measurements from the narrowband 415-nm channel were used to demonstrate a retrieval of the cloud properties of interest. With the proven operation of the relatively inexpensive TCRSR instrument, its usefulness for retrieving aerosol properties under cloud-free skies and for ship-based observations is discussed.

Full textAbstract:
Abstract Proton auroras are widely observed on the dayside of Mars, identified as a significant intensity enhancement in the hydrogen Lyα (121.6 nm) emission at altitudes of ∼110 and 150 km. Solar wind protons penetrating as energetic neutral atoms into Mars’ thermosphere are thought to be primarily responsible for these auroras. Recent observations of spatially localized “patchy” proton auroras suggest a possible direct deposition of protons into Mars’ atmosphere during unstable solar wind conditions. Improving our understanding of proton auroras is therefore important for characterizing the interaction of the solar wind with Mars’ atmosphere. Here, we develop a first purely data-driven model of proton auroras using Mars Atmosphere and Volatile Evolution (MAVEN) in situ observations and limb scans of Lyα emissions between 2014 and 2022. We train an artificial neural network that reproduces individual Lyα intensities and relative Lyα peak intensity enhancements with Pearson correlations of ∼94% and ∼60% respectively for the test data, along with a faithful reconstruction of the shape of the observed altitude profiles of Lyα emission. By performing a Shapley Additive Explanations (SHAP) analysis, we find that solar zenith angle, solar longitude, CO2 atmosphere variability, solar wind speed, and temperature are the most important features for the modeled Lyα peak intensity enhancements. Additionally, we find that the modeled peak intensity enhancements are high for early local-time hours, particularly near polar latitudes, and the induced magnetic fields are weaker. Through SHAP analysis, we also identify the influence of biases in the training data and interdependences between the measurements used for the modeling, and an improvement of those aspects can significantly improve the performance and applicability of the ANN model.

This paper presents surface temperature data collected over East Antarctic sea ice by two thermal infrared radiometers mounted on the RSV Aurora Australis in March-May 1993. Operating at wavelengths equivalent to those utilised by channels 4 and 5 of AVHRR and similar channels of ATSR, the radiometers provided high-reso-lution data on surface (skin) temperature along the ship track. Additional information on the sea-ice conditions was obtained from hourly observations made from The ship's bridge, video footage and direct measurements made at ice stations. Following calibration, time series of temperatures from each of the radiometers were compared wi th ice-surface and near-surface air temperatures. Observed changes in the surface temperature are related to different snow and ice conditions. For a given air temperature, the surface temperature depends upon the thickness of ice and its snow cover. While open water areas (leads) have temperatures near -2.0°C, thick ice is characterised by surface temperatures which approximate those of the air. Taken as a whole, the along-track profile of surface temperature provides a proxy estimate of The proportion of open water and thin ice with in the pack. The presence of a snow cover has a significant effect on the surface temperature. It is anticipated that the results will be of use in the validation of sea-ice models and satellite thermal infrared data.

AbstractShip-borne and airborne infrared radiometric measurements during the Arise cruise of September–October 2003 permitted in Situ validation Studies of two Satellite-based ice Surface Skin temperature algorithms: the AVHRR Polar Pathfinder Ice Surface Temperature and the MODIS Sea Ice Surface Temperature. Observations of Sea ice from the Aurora Australis Ship’s rail using a KT-19.82 radiometer were conducted between 25 September and 21 October during clear-sky overflights by AVHRR (41 passes) and MODIS (17 passes) on their respective Satellite platforms. Data from both Sensors Show highly linear fits to 1 min integrated radiometer Spot measurements, Spanning the range 245–270 K with a ±1.4˚C, 1σ (AVHRR) and ±1.0˚C (MODIS) variation relative to a 1: 1 relationship. There was no Significant offset. Helicopter observations made with a KT-19.85 radiometer on three dates (8, 19 and 20 October) provided more data (236 gridcell Sites total), but over a more limited Sea-ice Skin temperature range (252–268 K), with higher variation (±1.7˚C, 1σ) due to mixed-pixel issues. Comparison of MODIS and AVHRR algorithms directly, with both images acquired during a helicopter flight, indicates very high correlation and near-unity Slope for the two Satellite-based algorithms. Ship air-temperature data during the validation indicated moderate to Strong inversions over Sea ice under clear Skies. These formed and decayed rapidly (tens of minutes) as clouds moved out of and into the zenith area.

Abstract HASPIN, a mitotic kinase to phosphorylate Histone H3 at centromere, has been studied as a promising target for anti-cancer therapy. However, as HASPIN belongs to atypical kinase, lacking the Asp-Phe-Gly (DFG) motif, development from the chemical library of kinase inhibitors with conventional pharmacophore, would be technically challenging. In particular, one of adenosine analogues (LJ4827), a potent inhibitor of multi-kinases, showing clear anti-cancer activity in vitro and in vivo, was predicted as a HASPIN inhibitor by computation analysis of its transcriptome profile in cancer cells to drug-omic data set in the connectivity MAP (cMAP) as it shared similar transcriptome profile of 5-iodotubercidin (5ITU). The specificity and potency as HASPIN inhibitor of LJ4827 (IC50 = 0.45 nM) validated by in vitro kinase screening and consequent 3D structure modeling. As expected, treatment of LJ4827 in cancer cell lines efficiently delayed mitotic progression without double strand break (DSB) unlike 5ITU and significantly attenuated Aurora B localization at centromere. Along with clinical significance of HASPIN expression in lung cancer patients, mitotic gene signature closely associated to high expression of HASPIN, revealed the poor prognosis. Additional computational analysis of kinase perturbation data to predict the dependency of mitotic kinase in the absence of HASPIN activity, revealed the synthetic lethal effect of cotreatment of the chemical inhibitor of BUB1, PLK1 or AURKA with LJ4827. These data suggest that combined inhibition of HASPIN with the novel inhibitor and key mitotic kinases for centromere/kinetochore regulation would be effectivity therapeutic approach for cancer therapy.

Antarctica! The most hostile yet the breathtakingly beautiful landmass on the earth. It gives true feeling of vast dynamic forces of nature. Its haunting beauty is inspirational. It’s a place in the world where you experience absolute silence. Antarctica is the harshest, driest, coldest, windiest continent at the bottom of the earth. Treacherous weather yet a land of stunning panoramas, wide sweeping glaciers, turbulent ice-falls and vast majestic snow-covered landscapes. In summer, these are seen under a permanent sun that whirls relentlessly along the horizon and in winter continuous darkness obscures everything. Each sunrise and sunset are unique, and colours directly flow from heaven. The colours get reflected from pure white snow and there is a shower of many divine colours all around. Antarctica is a spiritual experience! Here the sun, moon do not always rise in the east and set in the west. The midnight sun sets for 10 minutes in the south at the beginning of winter here and the Polar night ends when sun rises for the first time in the North. Clouds with ice crystals give multiple images of sun, and cold weather plays tricks giving rise to astonishing mirages- don’t be surprised if you happen to see a ship or a piston bulley upside down! It is that part of the planet earth, where humans did not get a chance to interfere with nature. Southern Ocean encircling this continent freeze in winter resulting in doubling the size of the land mass-A pulsatile continent! Antarctica is cut off from the rest of the world during harsh winter months from March to October. Highest of all the continents, Lowest recorded temperatures (-89 degree) and violent snow storms (winds over 250 kmph); it’s indeed a unique place on earth! Its beauty is ethereal…On clear winter nights, there arise southern lights, or Aurora Australis from behind the ice shelf -often rolling waves of green, blue, red like a giant wheel of fairy dust. They are seen undulating over our head and spreading to fill the sky, moving like waves after waves; just like huge curtains spreading down from heaven. It was an emotional, life changing experience that one can only sit on the knees, hands folded, with tears in the eyes!

AbstractThe Lake District and smaller Craven inliers of northwest England contain a Lower Palaeozoic sequence deposited on the Gondwanan side of the Iapetus Ocean, close to the junction with the Tornquist Sea. The Tremadoc to Llanvirn Skiddaw and Ingleton groups are deep water assemblages of turbidite, olistostrome and slump deposits, formed at a continental margin. They experienced uplift and erosion as a precursor to the eruption of two largely subaerial Llandeilo-Caradoc volcanic sequences: the tholeiitic Eycott Volcanic Group in the north and the calc–alkaline Borrowdale Volcanic Group in the central Lake District. The volcanic episodes are the earliest part of a major episode of magmatism, extending through to the early Devonian and responsible for a major batholith underpinning the Lake District. Subsidence in an intra-arc rift zone preserved the subaerial volcanic sequences. A marine transgression marks the base of the Windermere Group, which comprises a mixed carbonate–clastic shelf sequence of Ashgill age, passing upwards through the Silurian into a thick, prograding foreland basin sequence of Ludlow turbidites. Deformation of the Lower Palaeozoic sequences was possibly diachronous from north to south. It is attributed to the late Caledonian (Acadian) Orogeny and resulted in folding, cleavage and thrust development. Granitic intrusions, including those at Shap, Skiddaw and beneath the hydrothermal Crummock Water Aureole, are partly syntectonic and were therefore penecontemporaneous with this deformation event. Some thrust faulting post-dates the intrusive phase. Post-deformation Devonian conglomerates are also present locally.

Full textAbstract:
The Shap Granite outcrops in eastern Cumbria, N.W. England and is a post—orogenic granite intruded during the Lower Devonian (ie 394 Ma) into rocks of Ordovician to Siturian age. It is of adamellite composition and is notable in having megacrysts of orthoclase which crystallised late (relative to the matrix) by an essentially metasomatic process. Late in its cooling history, hydrothermal fluids resulted in alteration ano mineralisation in and about the joint structures. Comparison of whole — rock element and stable isotope data between the hydrothermally — altered and non —altered granites shows that this late — stage process- was isochemical and only involved localised redistribution of the available elements, the hydrothermal fluid being derived from the granite itself and acting in a closed system. The associated suite of granitic dykes extends the chemical range of Shap granitic rocks from the restricted compositions of the granite itsetf (around 68%)to 62 to 77% Si02. Mineralogical and chemical evidence suggests that the Shap magma compositions were controlled mainly by biotite and plagioclase fractionation over much of this silica range. The granite is intruded about much of its outcrop into rocks of the mid—Ordovician, calk—alkaline Borrowdatt Volcanic Group. The aureate is lkm wide and 'generally displays limited contact metamorphic reactions apart from in the Blue Quarry, where higher sub—surface heat flow during the granite's intrusion resulted in localised more extreme metamorphic and some metasomatic conditions resulting in the development of garnet veins. Analysis of 61 samples from the aureole region show only very limited modifications to their original calk—alkaline chemistry. Stable isotope and the whole rock geochemistry indicates that the contact metamorphism was essentialty, isochemical and that chemical interaction with the granite did not occur. Aureole metamorphic reactions took place at moderate temperatures (250 — 400°C) apart from in a narrow (<1000 zone about the granite contact where temperatures may have reached close to those of the granite-solidus (around 600°C). Xenoliths from the 'granite Pink quarries at Shap contain the same mineralogy as their host granite, including the megacryst orthoclase. The xenolith chemistry compares well with that of the more basic dykes, with the xenoliths - forming a coherent group over the compositional range 56 to 674 Sia. Comparison with the country—rock chemistry shows that the xenoliths were not externally derived but probably represent quenched, more basic, comaqmatic melts related to the generation of the main Shap Granite magma. Limited Sr and Nd isotope data for the xenoliths show that these isotopes were in equilibrium with the granite and lends strong support for the cogeneric origins and chemical relationships for the granites, aykes and xenoliths together. The narrow aureole width is typical of those formed by conductive ratner convective cooling with interaction with the adjacent granite limited to thermal effects and not involving the cycling of fluids through the granite or aureole as in convective pluton cooling.

La polarité cellulaire est un déterminant essentiel dans le maintien de l’architecture tissulaire et la fonction de l’organe. Ainsi, la division cellulaire, la ciliogenèse, la prolifération, et la migration sont des évènements étroitement associés au processus de la polarisation cellulaire. L’altération de la polarité cellulaire contribue à la perte de l’intégrité des épithéliums et favorise le développement des cancers. La signalisation des lipides, telle que des phosphatidylinositols (PtdIns) joue un rôle vital dans la polarité apico-basale. Dans cette étude, nous avons développé des recherches pour mieux comprendre les mécanismes impliqués dans les effets de la phosphatase SHIP2 sur la polarité cellulaire. Nous avons pu démontrer que SHIP2 est impliquée dans la formation du site d’initiation de la formation de la lumière (AMIS) en régulant d’une part la contractilité acto-myosine induite par RhoA kinase et d’autre part YAP, un composant de la voie de signalisation Hippo. De plus, nous avons montré que l'inhibition de SHIP2 contribue à un défaut dans la formation de fuseau mitotique et dans le clivage de ce fuseau mitotique. La surexpression de SHIP2 induit une lumière large et des cils allongés attribuables à la diminution de l’expression de YAP, Aurora A et HEF1. Par contre, la diminution de l’expression de SHIP2 inhibe la formation des cils en provoquant la surexpression de YAP, Aurora A et HEF1 et ainsi l’apparition d’un phénotype multilumens. L’ensemble de nos travaux définissent un nouveau rôle de SHIP2 dans le maintien de l’intégrité et de l’homéostasie des cellules épithéliales. Nous avons aussi pu démontrer que l’expression de SHIP2 peut discriminer les différents cancers du foie (HCC, ICC et mixte) et que SHIP2 et Merlin/NF2, une protéine de la voie de signalisation Hippo, ont une forte expression dans le cholangiocarcinome (ICC) qui s’oppose à celle de YAP et de RhoA kinaseCell polarity is critical caracteristic for the maintenance of tissue architecture. Cell division, ciliogenesis, cell proliferation and migration are events tightly associated to cell polarization processes. Alteration in cell polarity contributes to loss of epithelium integrity and enhances cancer development. Lipids signaling, such as phosphatidylinositol (PtdIns), play a vital role in apico-basal polarity. In this study, we developed researches to better understand mechanisms implicated the role of the phosphatase SHIP2 in cell polarity. We demonstrated that SHIP2 is implicated in formation of the apical membrane initiation site (AMIS) by regulating YAP, a component of Hippo pathway, and RhoA-dependant acto-myosin contractility. Furthermore, we demonstrated that inhibition of SHIP2 contributes to defect in the formation and cleavage of the mitotic spindle. Overexpression of SHIP2 induced a large lumen with long cilia due to a decrease in YAP, Aurora A and HEF1 luminal localization. On the contrary, down regulation of SHIP2 impaired cilia outgrowth by increasing Aurora A, HEF1 and YAP luminal localization with appearance of a multilumens phenotype. Thus, our results reinforced the role of SHIP2 in maintain of integrity and homeostasis of epithelial cells. In this study, we also demonstrated that expression of SHIP2 distinguished the different types of liver cancer (HCC, ICC and mixte), and that SHIP2 and Merlin/NF2 are overexpressed in ICC which is the opposite of YAP and RhoA expression

AbstractAccurate and early prediction of arrhythmias using Electrocardiograms (ECG) presents significant challenges due to the non-stationary nature of ECG signals and inter-patient variability, posing difficulties even for seasoned cardiologists. Deep Learning (DL) methods offer precision in identifying diagnostic ECG patterns for arrhythmias, yet they often lack the transparency needed for clinical application, thus hindering their broader adoption in healthcare. This study introduces an explainable DL-based prediction model using ECG signals to classify nine distinct arrhythmia categories. We evaluated various DL architectures, including ResNet, DenseNet, and VGG16, using raw ECG data. The ResNet34 model emerged as the most effective, achieving an Area Under the Receiver Operating Characteristic (AUROC) of 0.98 and an F1-score of 0.826. Additionally, we explored a hybrid approach that combines raw ECG signals with Heart Rate Variability (HRV) features. Our explainability analysis, utilizing the SHAP technique, identifies the most influential ECG leads for each arrhythmia type and pinpoints critical signal segments for individual disease prediction. This study emphasizes the importance of explainability in arrhythmia prediction models, a critical aspect often overlooked in current research, and highlights its potential to enhance model acceptance and utility in clinical settings.

This chapter examines mid- to late-Victorian attempts at self-distancing from triumphalist (and literalist) early antislavery promises, focusing in particular on how the themes of haunting, displacement, and denial threaded through many later Victorians' patriotic invocations of liberating empire. Drawing on emerging pedagogical and scholarly revolutions in studies of nineteenth-century British relations to slavery, the chapter considers histories of disciplinary reticence dating back in part to the Victorians themselves. It also discusses the increasingly iconic histories of the 1840 World Anti-Slavery Convention and J.M.W. Turner's painting Slave Ship as well as Elizabeth V. Spelman's Fruits of Sorrow and her notion of “changing the subject.” Finally, it explores the discipline termed “ethical refocalization” by turning to three parallel scenes of interrupted Poetess performance, in Germaine de Staël's Corinne, or Italy; Elizabeth Barrett Browning's Aurora Leigh, and George Eliot's Spanish Gypsy.

This chapter assesses the sensational news regarding Manuel Quezon and Francis Burton Harrison. Quezon's numerous liaisons with women on both sides of the Pacific, as well as on ships while crossing the ocean, are legendary. While in his early twenties, Quezon married a poor rural beauty, but he later had the marriage annulled. A few years later he was convicted of attempted rape but escaped any penalty through the aid of his American advisers. So it was with some surprise that after ten years of speculation as to where his marital affections would land, he chose to marry his cousin Aurora Aragon Quezon a few days after leaving for Washington. Harrison's personal life was even more sordid. Married six times, Harrison was on his second marriage when he was named governor-general. Ultimately, Harrison's extravagant and reckless personal life produced at least eight children from five different marriages, along with numerous broken hearts and ruined lives. One might overlook Harrison's personal life if it had not affected his professional work. However, numerous sources confirm that he neglected his duties as governor-general in pursuit of women and sexual pleasure.

To investigate the ability of numerical models to simulate the behavior of moored ships subjected by ship-wake waves, use is made of scale model tests where a ship model sails with constant speed along a straight path at a constant distance from an otherwise motionless ship. The tests were carried out at one of the wave tanks of the Portuguese Civil Engineering Laboratory (LNEC). The moving ship is a self-propelled scale model of the “Aurora” chemical ship whereas the otherwise motionless ship is a scale model of the “Esso Osaka” tanker. The free-surface elevation was measured with a set of resistive wave gauges and ADVs. The tanker’s movements, induced by the wake waves, were measured along the six degrees of freedom with a gyroscope deployed inside the ship. The numerical model WAMIT provides, in the frequency domain, the quantities required to estimate the hydrodynamic forces associated to the interaction of a free-floating ship with waves. The BAS model uses those hydrodynamic forces to study in the time domain the ship interaction with any sea-waves acting on it. Wind and current actions can also be accounted for. The results of these numerical models are compared to the measurements made in the several repeats of one of those scale-model tests, in terms of the response amplitude to several wave components. These comparisons enabled the evaluation and validation of the numerical models parameters’ calibration process.

Full textAbstract:
The paper discusses the development of the AURORA BOREALIS, a new European Polar Research and Scientific Drilling Vessel with dynamical positioning capability in drifting ice. The Vessel will be designed as a heavy icebreaker with the highest polar ice class. She will be powered to break continuously multiyear ice of more than 2.5m thickness and she will be able to manage ice ridges up to 15m height and more. She shall perform research tasks including scientific drilling missions all-year-round in the Arctic and in Antarctica without any other assisting support vessels. One of the key issues in the required performance specification for the vessel is the mandatory performance of autonomous station keeping operations in drifting level ice of more than 2.0m thickness during drilling and other research tasks.

Cardiomegaly is a medical disorder characterized by an enlargement of the heart. Many works propose to automatically detect cardiomegaly through chest X-rays. However, most of them are based on deep learning models, known for their lack of interpretability. This work propose a deep learning model for the detection of cardiomegaly based on chest x-rays images and the qualitative assessment of three known local explainable methods, i.e., Grad-CAM, LIME and SHAP. Our model achieved Acc, Prec, Se, Spe, F1-score and AUROC of 91.8±0.7%, 74.0±2.7%, 87.0±5.5%, 92.9±1.2%, 79.8±1.9%, and 90.0±0.7%, respectively. Moreover, except for the SHAP method, our interpretable methods were able to pinpoint the expected location for cardiomegaly. However, Grad-CAM method showed faster computational time than LIME and SHAP.
