description: Acute thoracic aortic injury resulting from blunt trauma is a life-threatening condition. Endovascular therapy is a less invasive treatment modality that may potentially improve patient outcomes. We reviewed our experience with patients who sustained blunt thoracic aortic injuries distal to the left subclavian artery and presented for open surgical or endovascular repair.Between August 1993 and August 2006, 62 patients sustained blunt thoracic aortic injuries distal to the origin of the left subclavian artery and proceeded to undergo open surgical (n = 48, 77%), or endovascular repair (n = 14, 23%). Revised trauma score (RTS), injury severity score (ISS), new injury severity score (NISS), individual associated traumatic injuries, as well as operative and postoperative outcomes were compared between open surgical and endovascular groups.Age, gender, race, and mechanism of injury did not differ between open surgical and endovascular groups. Additionally, RTS, ISS, and NISS values were not significantly different. The proportion of patients with sternal fractures (14% vs 0%), or unstable spinal fractures (36% vs 10%) was significantly greater in the endovascular group. Of the patients who received endografts, 93% (n = 13) were evaluated by a cardiothoracic surgeon and assessed to be prohibitive to operative intervention. Endografts utilized included commercially manufactured thoracic endografts (n = 6; 43%) and abdominal aortic endograft components (n = 8; 57%). Forty-one interposition grafts were placed in the open surgical group. Renal complications (32% vs 7%), and urinary tract infections (35% vs 7%) approached significance between surgical and endovascular groups ( = .082 and = .077, respectively). Intraoperative mortality for the surgical and endovascular groups was 23% and 0%, respectively ( = .056). Endovascular repair was associated with significant reductions in operative time (118 vs 209 minutes), estimated blood loss (77 vs 3180 ml), and intraoperative blood transfusions (0.9 vs 6.1 units). No endoleaks were detected during a mean follow-up of 9.4 months in the endovascular group.Endovascular repair of blunt descending thoracic aortic injuries utilizing thoracic or abdominal endographs is a technically feasible modality that is at least equivalent to open therapy in the short term and associated with a lower intraoperative mortality ( = .056). Endovascular therapy has advantages in operative time, operative blood loss, and intraoperative blood transfusions.

description: Abstract Research on the acquisition order of inflectional morphemes in English has shown that third-person singular –s (3SG–s) is challenging to acquire and acquired later than be copula by both L1 and L2 learners of English. In a departure from the usual practice of controlled elicitation, the current study investigated the production of these two forms by Vietnamese EFL learners in oral communication tasks performed in intact classrooms. Vietnamese L1 does not inflectionally mark 3SG–s although the construction of be copula in Vietnamese and English shares some features. These differences motivated the selection of the two target forms. Nine pairs of Vietnamese EFL university students were recorded performing five communicative tasks generated contexts for use of 3SG–s. over three weeks in their normal classes. Performance data were transcribed and analyzed for frequencies of production and omission of the two target forms in obligatory contexts. After completing the tasks, the students were interviewed about what they attended to when performing the tasks. Interview transcripts were analyzed thematically. Results show that the learners omitted 3SG–s in most obligatory contexts and across all tasks. They were better at accurately producing be copula than 3SG–s but accuracy rates varied between learners. Interview data revealed the conscious decisions learners made concerning the accuracy of their language production. The findings are discussed with reference to different theoretical models. The study advances understanding of acquisition of 3SG–s and be copula by EFL learners and offers pedagogical implications for how a focus on inflectional forms can be managed in oral communicative task performance.

description: OBJECTIVE: This report summarizes the 30-day and 12-month results of endovascular treatment using the Medtronic Vascular Talent Thoracic Stent Graft System (Medtronic Vascular, Santa Rosa, Calif) for patients with thoracic aortic aneurysms (TAA) who are considered candidates for open surgical repair. METHODS: The study was a prospective, nonrandomized, multicenter, pivotal trial conducted at 38 sites. Enrollment occurred between December 2003 and June 2005. Standard follow-up interval examinations were prescribed at 1 month, 6 months, 1 year, and annually thereafter. These endovascular results were compared with retrospective open surgical data from three centers of excellence. RESULTS: The Evaluation of the Medtronic Vascular Talent Thoracic Stent Graft System for the Treatment of Thoracic Aortic Aneurysms (VALOR) trial enrolled 195 patients, and 189 were identified as retrospective open surgical subjects. Compared with the open surgery group, the VALOR test group had similar age and sex distributions, but had a smaller TAA size. Patients received a mean number of 2.7 +/- 1.3 stent graft components. The diameters of 25% of the proximal stent graft components implanted were <26 mm or >40 mm. Left subclavian artery revascularization was performed before the initial stent graft procedure in 5.2% of patients. Iliac conduits were used in 21.1% of patients. In 33.5% of patients, the bare spring segment of the most proximally implanted device was in zones 1 or 2 of the aortic arch. In 194 patients (99.5%), vessel access and stent graft deployment were successful at the intended site. The 30-day VALOR results included perioperative mortality, 2.1%; major adverse advents, 41%; incidence of paraplegia, 1.5%; paraparesis, 7.2%; and stroke, 3.6%. The 12-month VALOR results included all-cause mortality, 16.1%; aneurysm-related mortality, 3.1%; conversion to open surgery, 0.5%; target aneurysm rupture, 0.5%; stent graft migration >10 mm, 3.9%; endoleak (12.2%), stent graft patency, 100%; stable or decreasing aneurysm diameter, 91.5%; and loss of stent graft integrity, four patients. No deployment-related events or perforation of the aorta by a graft component occurred. The Talent Thoracic Stent Graft showed statistically superior performance with respect to acute procedural outcomes (P < .001), 30-day major adverse events (41% vs 84.4%, P < .001), perioperative mortality (2% vs 8%, P < .01), and 12-month aneurysm-related mortality (3.1% vs 11.6%, P < .002) vs open surgery. CONCLUSIONS: The pivotal VALOR 12-month trial results demonstrate that the Medtronic Talent Thoracic Stent Graft System is a safe and effective endovascular therapy as an alternative to open surgery in patients with TAA who were considered candidates for open surgical repair.

Failure and Uses of Jaynes' Principle of Transformation Groups

description: Bertand's paradox is a fundamental problem in probability that casts doubt on the applicability of the indifference principle by showing that it may yield contradictory results, depending on the meaning assigned to "randomness". Jaynes claimed that symmetry requirements (the principle of transformation groups) solve the paradox by selecting a unique solution to the problem. I show that this is not the case and that every variant obtained from the principle of indifference can also be obtained from Jaynes' principle of transformation groups. This is because the same symmetries can be mathematically implemented in different ways, depending on the procedure of random selection that one uses. I describe a simple experiment that supports a result from symmetry arguments, but the solution is different from Jaynes'. Jaynes' method is thus best seen as a tool to obtain probability distributions when the principle of indifference is inconvenient, but it cannot resolve ambiguities inherent in the use of that principle and still depends on explicitly defining the selection procedure.

description: Objective: This phase I IDE study (STAPLE-1) evaluated the primary endpoints of safety (major device-related adverse events at 30 days) and feasibility (successful deployment of all endograft components) of the Aptus Endovascular abdominal aortic aneurysm (AAA) Repair System (Aptus Endosystems, Inc, Sunnyvale, Calif) to treat AAAs. Methods: A prospective, single arm Federal Drug Administration (FDA) Phase I IDE study was performed. The Aptus endograft is a three-piece modular device with a flexible unsupported main body and two fully supported limbs in a 5.3 mmouter diameter (OD) (16F) delivery system for all iliac limbs and two of three main body sizes. The largest main body (29 mm diameter) is in a 6 mm (18 F OD) delivery system. EndoStaples measuring 4 mm (length) by 3 mm (diameter) designed to provide transmural graft fixation to the adventitia are applied independent of the endograft delivery system. Inclusion criteria included a proximal aortic neck length of 12 mm and iliac landing zone of 10 mm. Secondary endpoints included freedom from endoleaks, rupture, migration, and device integrity. Results: Twenty-one (21) patients were enrolled at five centers. All patients received the Aptus Endograft and EndoStaples. Ninety-six EndoStaples (range, 2-10; median, 4) were implanted. All patients (n = 21) completed 1-month and 6-month follow-up evaluation and 14 completed 1-year follow-up. Two proximal cuffs and one limb extension were used as adjunctive endograft components at implantation. Three secondary interventions were performed in 2 patients for limb thrombosis. There were no EndoStaple-related adverse events, device integrity failures, migrations, or conversions. Conclusion: These results of the STAPLE-1 trial document the acute safety and feasibility of the Aptus Endograft and EndoStaples. Early follow-up demonstrates excellent 6-month and 1-year results. A pivotal phase II trial is underway at 25 US centers. ( J Vasc Surg 2009;49:851-8.)

description:
BACKGROUND: People with human immunodeficiency virus (HIV) infection (PWH) are at higher risk of myocardial infarction (MI) than those without HIV. About half of MIs in PWH are type 2 (T2MI), resulting from mismatch between myocardial oxygen supply and demand, in contrast to type 1 MI (T1MI), which is due to primary plaque rupture or coronary thrombosis. Despite worse survival and rising incidence in the general population, evidence-based treatment recommendations for T2MI are lacking. We used polygenic risk scores (PRS) to explore genetic mechanisms of T2MI compared to T1MI in PWH. METHODS: We derived 115 PRS for MI-related traits in 9541 PWH enrolled in the Centers for AIDS Research Network of Integrated Clinical Systems cohort with adjudicated T1MI and T2MI. We applied multivariate logistic regression analyses to determine the association with T1MI and T2MI. Based on initial findings, we performed gene set enrichment analysis of the top variants composing PRS associated with T2MI. RESULTS: We found that T1MI was strongly associated with PRS for cardiovascular disease, lipid profiles, and metabolic traits. In contrast, PRS for alcohol dependence and cholecystitis, significantly enriched in energy metabolism pathways, were predictive of T2MI risk. The association remained after the adjustment for actual alcohol consumption. CONCLUSIONS: We demonstrate distinct genetic traits associated with T1MI and T2MI among PWH further highlighting their etiological differences and supporting the role of energy regulation in T2MI pathogenesis.

description: Transition edge sensor microcalorimeters can measure x-ray and gamma-ray energies with very high energy resolution and high photon-collection efficiency. For this technology to reach its full potential in future x-ray observatories, each sensor must be able to measure hundreds or even thousands of photon energies per second. Current "optimal filtering" approaches to achieve the best possible energy resolution work only for photons well isolated in time, a requirement in direct conflict with the need for high-rate measurements. We describe a new analysis procedure to allow fitting for the pulse height of all photons even in the presence of heavy pulse pile-up. In the limit of isolated pulses, the technique reduces to the standard optimal filtering with long records. We employ reasonable approximations to the noise covariance function in order to render multi-pulse fitting computationally viable even for very long data records. The technique is employed to analyze x-ray emission spectra at 600 eV and 6 keV at rates up to 250 counts per second in microcalorimeters having exponential signal decay times of approximately 1.2 ms.

description: A novel hybrid system composed of sepiolite clay and cyclodextrin nanosponge (CDNS) was prepared via reaction of Cl-functionalized sepiolite with amine-functionalized CDNS. CDNS–sepiolite was then applied for immobilization of Pd(0) nanoparticles. The resulting hybrid system, Pd@CDNS-sepiolite, was characterized using various techniques and successfully used as an efficient and heterogeneous catalyst for ligand- and copper-free Sonogashira and Heck coupling reactions under mild reaction conditions. Recycling experiments confirmed that Pd@CDNS-sepiolite was recyclable and could be used for several consecutive reaction runs with slight Pd leaching and loss of catalytic activity.

Stability of viscous St. Venant roll-waves: from onset to infinite-Froude number limit

description: We study the spectral stability of roll-wave solutions of the viscous St. Venant equations modeling inclined shallow-water flow, both at onset in the small-Froude number or "weakly unstable" limit $F\to 2^+$ and for general values of the Froude number $F$, including the limit $F\to +\infty$. In the former, $F\to 2^+$, limit, the shallow water equations are formally approximated by a Korteweg de Vries/Kuramoto-Sivashinsky (KdV-KS) equation that is a singular perturbation of the standard Korteweg de Vries (KdV) equation modeling horizontal shallow water flow. Our main analytical result is to rigorously validate this formal limit, showing that stability as $F\to 2^+$ is equivalent to stability of the corresponding KdV-KS waves in the KdV limit. Together with recent results obtained for KdV-KS by Johnson--Noble--Rodrigues--Zumbrun and Barker, this gives not only the first rigorous verification of stability for any single viscous St. Venant roll wave, but a complete classification of stability in the weakly unstable limit. In the remainder of the paper, we investigate numerically and analytically the evolution of the stability diagram as Froude number increases to infinity. Notably, we find transition at around $F=2.3$ from weakly unstable to different, large-$F$ behavior, with stability determined by simple power law relations. The latter stability criteria are potentially useful in hydraulic engineering applications, for which typically $2.5\leq F\leq 6.0$.

description: The dynamical system studied in previous papers of this series, namely a bound time-like geodesic motion in the exact static and axially symmetric space-time of an (originally) Schwarzschild black hole surrounded by a thin disc or ring, is considered to test whether the often employed "pseudo-Newtonian" approach (resorting to Newtonian dynamics in gravitational potentials modified to mimic the black-hole field) can reproduce phase-space properties observed in the relativistic treatment. By plotting Poincaré surfaces of section and using two recurrence methods for similar situations as in the relativistic case, we find similar tendencies in the evolution of the phase portrait with parameters (mainly with mass of the disc/ring and with energy of the orbiters), namely those characteristic to weakly non-integrable systems. More specifically, this is true for the Paczyński--Wiita and a newly suggested logarithmic potential, whereas the Nowak--Wagoner potential leads to a different picture. The potentials and the exact relativistic system clearly differ in delimitation of the phase-space domain accessible to a given set of particles, though this mainly affects the chaotic sea whereas not so much the occurrence and succession of discrete dynamical features (resonances). In the pseudo-Newtonian systems, the particular dynamical features generally occur for slightly smaller values of the perturbation parameters than in the relativistic system, so one may say that the pseudo-Newtonian systems are slightly more prone to instability. We also add remarks on numerics (a different code is used than in previous papers), on the resemblance of dependence of the dynamics on perturbing mass and on orbital energy, on the difference between the Newtonian and relativistic Bach--Weyl rings, and on the relation between Poincaré sections and orbital shapes within the meridional plane.

Modernist Impersonality in the Poetry of Sylvia Plath

Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: This thesis revises strictly autobiographical and confessional readings of Sylvia Plath’s poetry by attending to the legacies of modernism present in her representations of the self. In reassessing the popular idea that Plath’s poems illustrate a linear narrative towards self-revelation, mired by the assumed predeterminism of her suicide, this thesis at once situates Plath within her literary, social, and cultural contexts of mid-century America and Britain, and analyses the poetic means in which Plath resists or defers stable significations of subjectivity. Rather than being highly individualised and inextricably personal evocations of selfhood, Plath’s subjective representations instead develop out of spatially situated engagements between self and world, destabilising the perceived location of knowledge and truth from within the contained borders of the self. This unfolding of multiple and indeterminate meanings of the self, contingent upon its entanglement with past and present discursive influences at the time of Plath’s writing, will be examined through the framework of modernist impersonality. Arguing against traditional understandings of impersonality as a repudiation of the self and its emotional experiences, I instead demonstrate how Plath’s deployment of impersonality reflects a revised approach that emphasises its potential to procure new affective reformulations of subjectivity in its engagement and orientation towards the world. Plath’s impersonal mode subsequently reconfigures features of her selfhood that have previously served to align with a perceived autobiographical self; instead, it reveals an embodied and embedded self that reconstructs and reimagines present and future boundaries within her textual world.

description: We present the results of deep \chandra\ imaging of the central region of the Extended Groth Strip, the AEGIS-X Deep (AEGIS-XD) survey. When combined with previous \chandra\ observations of a wider area of the strip, AEGIS-X Wide (AEGIS-XW; Laird et~al. 2009), these provide data to a nominal exposure depth of 800ks in the three central ACIS-I fields, a region of approximately $0.29$~deg$^{2}$. This is currently the third deepest X-ray survey in existence, a factor $\sim 2-3$ shallower than the Chandra Deep Fields (CDFs) but over an area $\sim 3$ times greater than each CDF. We present a catalogue of 937 point sources detected in the deep \chandra\ observations. We present identifications of our X-ray sources from deep ground-based, Spitzer, GALEX and HST imaging. Using a likelihood ratio analysis, we associate multi band counterparts for 929/937 of our X-ray sources, with an estimated 95~\% reliability, making the identification completeness approximately 94~\% in a statistical sense. Reliable spectroscopic redshifts for 353 of our X-ray sources are provided predominantly from Keck (DEEP2/3) and MMT Hectospec, so the current spectroscopic completeness is $\sim 38$~per cent. For the remainder of the X-ray sources, we compute photometric redshifts based on multi-band photometry in up to 35 bands from the UV to mid-IR. Particular attention is given to the fact that the vast majority the X-ray sources are AGN and require hybrid templates. Our photometric redshifts have mean accuracy of $σ=0.04$ and an outlier fraction of approximately 5\%, reaching $σ=0.03$ with less than 4\% outliers in the area covered by CANDELS . The X-ray, multi-wavelength photometry and redshift catalogues are made publicly available.

description: Achalasia is a chronic esophageal disorder that affects the motility of the esophagus, making it difficult for aliments to pass into the stomach. It is characterized by a lack of coordination in the esophageal muscles and a lower esophageal sphincter that does not relax during swallowing. This causes dysphagia, regurgitation of aliments, a feeling of obstruction in the chest and weight loss due to decreased intake. The cause is related to the degeneration of nerve cells in the esophagus. Diagnosis is made through imaging studies and esophageal function tests. Treatment may include medications to relax the sphincter, esophageal dilation or, in severe cases, surgical management.

description: BACKGROUND: Iliocaval venous obstruction (ICVO) can be a significant contributor to venous hypertension in patients with advanced disease. The incidence of ICVO in patients with CEAP clinical class 5 and 6 disease has not been reported. In this study, we reviewed a series of patients with healed or active venous leg ulcers to determine the incidence of ICVO and the risk factors related to its occurrence. METHODS: Patients with CEAP clinical class 5 and 6 venous insufficiency underwent evaluation with duplex ultrasound scan to identify the presence of venous reflux in the deep and superficial systems and either computed tomography (CT) or magnetic resonance (MR) venography to identify ICVO. The venograms were evaluated by two separate examiners to calculate the percentage of obstruction in the iliocaval outflow tract. Demographics and risk factors related to venous disease were collected and examined for their association with severe ICVO. RESULTS: A total of 78 CEAP clinical class 5 and 6 patients evaluated with either a CT or MR venogram were retrospectively reviewed. The average patient age was 59.3 years and 53.4% were men. The ulcer affected the left lower extremity in 46% of cases and 50% of patients reported a medical history of deep vein thrombosis (DVT). Overall, 37% of imaging studies demonstrated ICVO of at least 50% and 23% had obstruction of >80%. Risk factors that were found to be independently associated with a significantly higher incidence of >80% ICVO included female gender (P = .023), a medical history of DVT (P = .035), and reflux in the deep venous system (P = .035). No limb with superficial venous reflux (SVR) alone was found to have ICVO >80%. CONCLUSIONS: ICVO is a frequent and underappreciated contributor to venous hypertension in patients with venous leg ulcers. Women and patients with a history of DVT or duplex scan-diagnosed deep venous reflux (DVR) have a higher incidence of outflow obstruction and should be routinely studied with CT or MR venography to allow correction in this high-risk group of patients.

description: OBJECTIVE: We report the 5-year outcomes of thoracic endovascular aneurysm repair (TEVAR) using the Medtronic Vascular Talent Thoracic Stent Graft System (Medtronic Vascular, Santa Rosa, Calif) in patients considered low or moderate risk for open surgical repair. METHODS: The Evaluation of the Medtronic Vascular Talent Thoracic Stent Graft System for the Treatment of Thoracic Aortic Aneurysms (VALOR) trial was a prospective, nonrandomized, multicenter, pivotal study conducted at 38 U.S. sites. Between December 2003 and June 2005, VALOR enrolled 195 patients who were low or moderate risk (0, 1, and 2) per the modified Society for Vascular Surgery and American Association for Vascular Surgery criteria. The patients had fusiform thoracic aortic aneurysms (TAAs) and/or focal saccular TAAs/penetrating atherosclerotic ulcers. Standard follow-up interval examinations were conducted at 1 month, 6 months, 1 year, and annually thereafter. RESULTS: Over the 5-year follow-up, 76 deaths occurred (43.9%). Freedom from all-cause mortality was 83.9% at 1 year and 58.5% at 5 years. Most deaths were due to cardiac, pulmonary or cancer-related causes. Freedom from aneurysm-related mortality (ARM) was 96.9% at 1 year and 96.1% at 5 years. There was only 1 case of ARM after the first year of follow-up. Over the 5-year follow-up period, four patients were converted to open surgery and four patients experienced aneurysm rupture. The 5-year freedom from aneurysm rupture was 97.1% and the 5-year freedom from conversion to surgery was 97.1%. The incidence of stent graft migration (>10 mm) was ≤ 1.8% in each year of follow-up. The rate of type I endoleak was 4.6% at 1 month, 6.3% from 1 month to 1 year, and 3.8% during year 5. The rate of type III endoleak was 1.3% at 1 month, 1.9% from 1 month to 1 year, and 1.9% during year 5. Through 5 years, 28 patients (14.4%) underwent 31 additional endovascular procedures on the original target lesion. The 5-year freedom from secondary endovascular procedures was 81.5%. CONCLUSIONS: Through 5-year follow-up in patients who were candidates for open surgical repair, TEVAR using the Talent Thoracic Stent Graft System has demonstrated sustained protection from ARM, aneurysm rupture, and conversion to surgery, and durable stent graft performance. Close patient follow-up remains essential after TEVAR.

description: With recent advances in asteroseismology it is now possible to peer into the cores of red giants, potentially providing a way to study processes such as nuclear burning and mixing through their imprint as sharp structural variations -- glitches -- in the stellar cores. Here we show how such core glitches can affect the oscillations we observe in red giants. We derive an analytical expression describing the expected frequency pattern in the presence of a glitch. This formulation also accounts for the coupling between acoustic and gravity waves. From an extensive set of canonical stellar models we find glitch-induced variation in the period spacing and inertia of non-radial modes during several phases of red-giant evolution. Significant changes are seen in the appearance of mode amplitude and frequency patterns in asteroseismic diagrams such as the power spectrum and the échelle diagram. Interestingly, along the red-giant branch glitch-induced variation occurs only at the luminosity bump, potentially providing a direct seismic indicator of stars in that particular evolution stage. Similarly, we find the variation at only certain post-helium-ignition evolution stages, namely, in the early phases of helium-core burning and at the beginning of helium-shell burning signifying the asymptotic-giant-branch bump. Based on our results, we note that assuming stars to be glitch-free, while they are not, can result in an incorrect estimate of the period spacing. We further note that including diffusion and mixing beyond classical Schwarzschild, could affect the characteristics of the glitches, potentially providing a way to study these physical processes.

description: Оценка точек контакта потребителя с предприятием сферы услуг является актуальным исследовательски вектором индивидуализированного маркетинга. Это обусловлено переносом акцентов в концепции маркетинга с удовлетворения нужд и потребностей клиентов на построение сценариев потребительского поведения с учетом точек контакта, где потребитель по факту становится отдельным сегментом рынка. Цель данного исследования - проанализировать существующие и найти недоработанные точки контакта потребителей с предприятием общественного питания. В рамках данного исследования проведен опрос экспертов ресторанного бизнеса и потребителей (выборка составила 243 респондента) на основе разработанного авторского конструкта. Основной идеей предложенного инструментария является рассмотрение клиентского опыта до, во время и после посещения предприятия общественного питания. Полученные результаты позволили зафиксировать приоритетные точки контакты, проанализировать их значимость, выделить недоработанные со стороны предприятия, но значимые для потребителя. Наиболее интересным результатом данного исследования является фиксация недоработанных точек контакта потребителей с предприятием общественного питания. Дальнейшее направление исследований должно идти по пути развития методологии построения сценариев поведения потребителей на основе оценки точек контакта.

description: Presentation given at EGU 2020 - doi.org/10.5194/egusphere-egu2020-9732 In the roadmap of modern parallel architectures development, the computing power of a node grows much more quickly than main memory performance (capacity, bandwidth). This leads to an even much higher gap between computing and memory resources. An efficient use of the cache memory is becoming ever more essential as optimization technique. The NEMO model uses a finite difference integration method and a regular cartesian grid for space discretization. The NEMO code reflects this choice: a generic field is represented in memory as a 3D array; and the code is mainly composed of three-level nested loops. These loops often include only a few operations in the body; the results are stored in a temporary 3D array and then used in subsequent loops until the final calculation.
 The aim of this work is to make better use of the cache memory by fusing DO loops together. The loop fusion is a transformation which takes two or more adjacent loops that have the same iteration space traversal and combines their bodies into a single loop.
 The fusion of the loops is not trivial, and it could require introducing additional redundant operations to solve data dependencies. Unfortunately, this leads to a drawback of the overall performance. To avoid the redundant operation, we can adopt pointers to arrays and implement a pointer rotation at each loop iteration.
 We have developed the loop fusion transformation in an advection kernel extracted from the NEMO oceanic model. We have compared 3 different versions of the optimized advection kernel, with 3 different levels of loop fusion.
 The first prototype refers to the implementation where the extreme fusion is applied, and all loops in the routine have been fused. In this version, the operations are replicated up to 3 times. In the second prototype the buffer rotation has been applied only in the outermost loop. In the third prototype, the buffer rotation has also been implemented for the second dimension, and this version introduces only a limited amount of redundant operations.
