Reservoir Characterisation Using Distributed Temperature Sensing in CSG Development: Application in the Surat Basin, Queensland, Australia
Authors: Furniss J. P. , Schouten J. , Bottomley W. , Taylor H. 
Published: September 2014

Abstract
This paper discusses the use of distributed temperature sensing (DTS) in QGC's Surat Basin wells, and how this new technology has been used to improve reservoir characterisation through enhanced resolution of zonal productivity and flowing contributions.
In stacked reservoirs with zones of varying quality, it is vitally important to allocate production volumes to flowing zones in order to adequately characterise the reservoir and create a representative dynamic simulation model that can accurately match reservoir productivity and depletion.
For conventional oil and gas production, subsurface allocation of flowing contributions can be achieved through the use of production logging tools, which provide a measurement of volumetric flow rate and fluid density along the completed well length. The nature of Coal Seam Gas (CSG) well completions reduces the options available for allocation of flow to zones. Also, the producing characteristics of a CSG well can make this zonal allocation more complicated. Firstly, the lower zones of QGC's Surat wells are subject to higher back-pressure due to the column of water sat in the annulus, rising above the pump location. Secondly, the de-watering and subsequent de-sorption periods complicate matters, where initially 100% water flows from a zone followed by a gradually increasing gas-water-ratio: the rate of transition from water to gas production is expected to be different for each producing zone. Additionally, due to the stress dependency of coal fracture permeability during the de-watering phase, and later the impact of gas de-sorption on fracture permeability, different zones might be expected to show larger or smaller changes in productivity with time: to understand this would require repeatable measurements through the production life of wells.
In this work, DTS technology has been proven, for the first time in QGC's Surat CSG wells, as a means of achieving subsurface allocation of well test kh. This is important for the justification of permanent installations that will allow ongoing zonal allocation of produced volumes. The impact of this methodology on history match quality and reservoir characterisation accuracy is discussed. It is suggested that these new workflows could prove very beneficial in the characterisation of CSG reservoirs.

ABSTRACTPlanting rhizoma peanut (RP; Arachis glabrata Benth.) in strips in bahiagrass (Paspalum notatum Flügge) pastures may be an economical approach to increase sward nutritive value, decrease dependence on N fertilizer, and promote sustainable mixed‐species pastures. Released cultivars and germplasms of RP range in growth habit from decumbent to upright, differences that may affect their spread and response to defoliation in grass pastures. The objectives were to quantify initial establishment characteristics and subsequent spread of RP entries following strip planting. Treatments were the factorial combinations of two defoliation practices after planting (haying or grazing every 28 d) and four RP entries (Arblick, Ecoturf, Florigraze, and UF Peace). By the year after planting, decumbent types Arblick (51%) and Ecoturf (48%) had greater RP ground cover than upright‐growing UF Peace (34%), but they were not different in cover than the intermediate type Florigraze (40%). Haying resulted in greater cover than grazing (51 vs. 31%). Spread of RP into adjacent bahiagrass was reduced by grazing compared with haying during the year of planting (0 and 0.24 m, respectively) and year after planting (0.34 and 0.67 m, respectively). Results suggest that decumbent Ecoturf and Arblick and intermediate growth habit Florigraze can be established successfully in strips in bahiagrass pasture, and establishment is favored when swards are used for hay rather than grazing during the first 2 yr.
Methods for estimating vehicle queues at a marine terminal: A computational comparison
Authors: Chen Gang , Yang Zhong-Zhen 
Published: September 2014

Abstract
A long queue of vehicles at the gate of a marine terminal is a common traffic phenomenon in a port-city, which sometimes causes problems in urban traffic. In order to be able to solve this issue, we firstly need accurate models to estimate such a vehicle queue length. In this paper, we compare the existing methods in a case study, and evaluate their advantages and disadvantages. Particularly, we develop a simulation-based regression model, using the micro traffic simulation software PARAMIC. In simulation, it is found that the queue transient process follows a natural logarithm curve. Then, based on these curves, we develop a queue length estimation model. In the numerical experiment, the proposed model exhibits better estimation accuracy than the other existing methods

Published: September 2014

Abstract
Background: Esophageal varices (EVs) are serious consequences of liver cirrhosis. Several studies have evaluated the possible non-invasive markers for the diagnosis of EVs to reduce the number of endoscopic procedures in patients with cirrhosis but without varices. This study was performed to evaluate the diagnostic performance of two such parameters (platelet count to splenic diameter ratio and splenoportal index) for the detection of EVs. Materials and Methods: A total of 111 patients with liver cirrhosis were analyzed after performing upper gastrointestinal endoscopy and non-invasive tests including platelet count and ultrasound abdomen including Doppler study. Appropriate statistical tests were applied to compare the non-invasive tests with the gold standard of endoscopy. Results: Of 111 liver cirrhotics, 80 (72.1%) were male and 31 (27.9%) were female. EVs were present in 68 (61.3%) patients and absent in 43 (38.7%) patients. In platelet count to splenic diameter ratio, a cut-off value of 1014 was obtained, which gave a sensitivity of 75.0%, specificity of 65.1%, positive predictive value (PPV) of 77.3%, negative predictive value (NPV) of 62.2% and diagnostic accuracy of 71.2%. In the splenoportal index, a cut-off value of 3.5 cm/s was obtained, which gave a sensitivity of 79.4%, specificity of 72.0%, PPV of 81.8%, NPV of 68.8% and diagnostic accuracy of 76.5% for the diagnosis of EVs. Conclusions: The platelet count to spleen diameter ratio and splenoportal index are non-invasive and fairly accurate alternatives in identifying the presence or absence of EVs in patients with compensated cirrhosis.

Published: September 2014

Abstract
Background: Trigger finger is a common problem encountered in rheumatologic practice that causes a triggering or locking that may produce an uncomfortable sensation. There are various methods of treatment, ranging from conservative management to surgical release. Aim: To determine the effectiveness of corticosteroid injection and percutaneous release in terms of symptomatic relief, patient satisfaction and complications. Materials and Methods: In this prospective study, 50 patients who presented with trigger finger Grades 2 and 3 were randomized into two groups. One group received corticosteroid injection and, in the other group, percutaneous release was performed. These patients were then assessed weekly over a period of 6 weeks and their progress was noted. Results: Thirty cases (60%) were female and 20 cases (40%) were male. The age of the patients in this study was 40-65 years (mean: 48 years). Twenty-three cases (46%) were manual workers, 17 cases (34%) were semi-professionals and 10 cases (20%) were housewives. Most of the patients had involvement of the dominant hand (62%) and non-dominant hand involved in 38% of the cases. The most common presenting symptom was pain with triggering. In both groups, significant improvement in pain and triggering occurs in the first 2 weeks, but there was better improvement of pain and triggering in the corticosteroid group after 2 weeks. In terms of swelling of the digits, no difference was noted during the course of the treatment in the two groups. The corticosteroid group of patients had a complication rate of 6% and in the second group, the percutaneous group, had an 18% complication rate. There were a total of 12 patients who had recurrence (recurrence rate 24%): five (41.6%) cases in the first or corticosteroid group and seven (58.3%) cases in the surgery group. Conclusion: The group of patients treated with corticosteroid had a better relief of pain and triggering and had a lower complication rate. The recurrence was equal in both groups.

Published: September 2014

Abstract
Spontaneous acute esophageal necrosis (AEN) has been reported to be extremely rare. The condition is defined as a dark pigmentation of the esophagus associated with histologic mucosal necrosis. The exact pathogenesis is still unknown, but several etiologies have been suggested including ischemia, gastric outlet obstruction, hypersensitivity to antibiotics, gastric volvulus and viral infection. We herein present a case of a middle-aged man with end-stage renal disease who presented with AEN following a hemodialysis session. Its diagnosis and management are discussed with reference to the pathogenesis of the condition.
Parallelization of an Implicit Algorithm for Multi-Dimensional Particle-in-Cell Simulations
Authors: Petrov George M. , Davis Jack 
Published: September 2014

AbstractThe implicit 2D3V particle-in-cell (PIC) code developed to study the interaction of ultrashort pulse lasers with matter [G. M. Petrov and J. Davis, Computer Phys. Comm. 179, 868 (2008); Phys. Plasmas 18, 073102 (2011)] has been parallelized using MPI (Message Passing Interface). The parallelization strategy is optimized for a small number of computer cores, up to about 64. Details on the algorithm implementation are given with emphasis on code optimization by overlapping computations with communications. Performance evaluation for 1D domain decomposition has been made on a small Linux cluster with 64 computer cores for two typical regimes of PIC operation: “particle dominated”, for which the bulk of the computation time is spent on pushing particles, and “field dominated”, for which computing the fields is prevalent. For a small number of computer cores, less than 32, the MPI implementation offers a significant numerical speed-up. In the “particle dominated” regime it is close to the maximum theoretical one, while in the “field dominated” regime it is about 75-80 % of the maximum speed-up. For a number of cores exceeding 32, performance degradation takes place as a result of the adopted 1D domain decomposition. The code parallelization will allow future implementation of atomic physics and extension to three dimensions.
S’affirmer en tant que Nation

Par la Loi sur les Indiens, les sociétés amérindiennes se sont fait imposer un nouvel univers politique par les autorités canadiennes. Elles ont donc dû composer avec le système des conseils de bande en s'adaptant et en réaménageant leurs façons de faire politiques. La tradition diplomatique algonquienne, bien active au XVIIe siècle et encore durant une partie du XVIIIe, s'est-elle aussi transformée? Depuis la vague de mouvement d'affirmation autochtone des années 1970, les relations des conseils de bande ne se limitent plus au gouvernement canadien, aux autres nations autochtones ou aux relations avec des instances non autochtones locales, régionales, provinciales ou pan canadiennes: elles s'étendent désor mais aussi au niveau international. Peut-on maintenant utiliser le mot « diplomatie » dans le contexte des conseils de bande? À l'aide de l'exemple de la communauté algonquine de Kitigan Zibi, l'auteure explore la participation active de cette bande à des rencontres avec les ambassadeurs de divers pays représentés à Ottawa. L'affirmation d'une identité nationale et la reconnaissance politique de la bande sont au coeur de cette démarche entreprise par les Anishnabeg.
Le Travailleur de Worcester et la lutte pour la survivance de la Franco-Américanie, 1931-1950
Authors: Noël Mathieu 
Published: September 2014

Fondé en 1931 par Wilfrid Beaulieu, l’hebdomadaire Le Travailleur se présente comme « le défenseur attitré de la religion [catholique] et de la langue [française] » en Nouvelle-Angleterre. Dans cet article, nous avons cherché à déterminer quels étaient les principaux enjeux sociopolitiques abordés par l’équipe du journal, de sa fondation jusqu’en 1950. D’abord, la thèse de la survivance est défendue avec vigueur tout au long des années 1930. Durant la Seconde Guerre mondiale, le principal enjeu devient celui de la libération de la France. Finalement, à partir de 1945, Beaulieu essaie, non sans difficulté, de recentrer son journal sur l’idée de la survivance de la Franco-Américanie.

ImportanceThe reasons for the increased fracture risk in type 2 diabetes (T2D) are not fully understood.ObjectiveTo determine if poorer skeletal characteristics or worse physical function explain the increased fracture risk in T2D.Design, Setting, and ParticipantsThis prospective observational study is based on the population-based Sahlgrenska University Hospital Prospective Evaluation of Risk of Bone Fractures study cohort of older women, performed in the Gothenburg area between March 2013 and May 2016. Follow-up of incident fracture data was completed in March 2023. Data analysis was performed between June and December 2023.ExposuresData were collected from questionnaires and through examination of anthropometrics, physical function, and bone measurements using bone densitometry (dual-energy x-ray absorptiometry), and high-resolution peripheral computed tomography. A subsample underwent bone microindentation to assess bone material strength index (BMSi).Main Outcomes and MeasuresBaseline assessment of bone characteristics and physical function and radiograph verified incident fractures.ResultsOf 3008 women aged 75 to 80 years, 294 women with T2D (mean [SD] age, 77.8 [1.7] years) were compared with 2714 women without diabetes (mean [SD] age, 77.8 [1.6] years). Women with T2D had higher bone mineral density (BMD) at all sites (total hip, 4.4% higher; femoral neck (FN), 4.9% higher; and lumbar spine, 5.2% higher) than women without. At the tibia, women with T2D had 7.4% greater cortical area and 1.3% greater density, as well as 8.7% higher trabecular bone volume fraction. There was no difference in BMSi (T2D mean [SD], 78.0 [8.3] vs controls, 78.1 [7.3]). Women with T2D had lower performance on all physical function tests. The study found 9.7% lower grip strength, 9.9% slower gait speed, and 13.9% slower timed up-and-go time than women without diabetes. During a median (IQR) follow-up of 7.3 (4.4-8.4) years, 1071 incident fractures, 853 major osteoporotic fractures (MOF), and 232 hip fractures occurred. In adjusted (for age, body mass index, clinical risk factors, and FN BMD) Cox regression models, T2D was associated with an increased risk of any fracture (HR, 1.26; 95% CI, 1.04-1.54) and MOF (HR, 1.25; 95% CI, 1.00-1.56).Conclusions and RelevanceIn this cohort study of older women, T2D was associated with higher BMD, better bone microarchitecture, and no different BMSi but poorer physical function, suggesting that poor physical function is the main reason for the increased fracture risk in T2D women.

AbstractHomologous recombination deficiency (HRD) score is a reliable indicator of genomic instability. The significance of HRD in nasopharyngeal carcinoma (NPC), particularly its influence on prognosis and the immune microenvironment, has yet to be adequately explored. Understanding HRD status comprehensively can offer valuable insights for guiding precision treatment. We utilised three cohorts to investigate HRD status in NPC: the Zhujiang cohort from local collection and the Hong Kong (SRA288429) and Singapore (SRP035573) cohorts from public datasets. The GATK (genome analysis toolkit) best practice process was employed to investigate germline and somatic BRCA1/2 mutations and various bioinformatics tools and algorithms to examine the association between HRD status and clinical molecular characteristics. We found that individuals with a negative HRD status (no‐HRD) exhibited a higher risk of recurrence [hazard ratio (HR), 1.43; 95% confidence interval (CI), 2.03–333.76; p = 0.012] in the Zhujiang cohort, whereas, in the Singapore cohort, they experienced a higher risk of mortality (HR, 26.04; 95% CI, 1.43–34.21; p = 0.016) compared with those in the HRD group. In vitro experiments demonstrated that NPC cells with BRCA1 knockdown exhibit heightened sensitivity to chemoradiotherapy. Furthermore, the HRD group showed significantly higher tumour mutational burden and tumour neoantigen burden levels than the no‐HRD group. Immune infiltration analysis indicated that HRD tissues tend to have a non‐inflamed tumour microenvironment. In conclusion, patients with HRD exhibit a comparatively favourable prognosis in NPC, possibly associated with a non‐inflammatory immune microenvironment. These findings have positive implications for treatment stratification, enabling the selection of more precise and effective therapeutic approaches and aiding in the prediction of treatment response and prognosis to a certain extent.
An Enhanced Extend Interface via the π–π Interaction to Achieve the Soluble Light‐Assisted Lithium–Oxygen Batteries

Published: August 2024

AbstractThe light‐assisted strategy is considered as an effective way to reduce the overpotential of lithium‐oxygen (Li─O2) batteries, however, the generated solid discharge products are prone to cover active sites of the solid‐state photocatalyst, causing the premature death of the cell. Herein, for the first time, the feasibility of soluble photocatalysts in Li─O2 battery system using Iron (II) Phthalocyanine (FePc) is verified. A micro reaction channel is constructed between the sp2‐carbon cathode and the soluble photocatalyst‐phthalein iron through π–π interaction, which can effectively increase the three‐phase reaction interface, facilitating the rapid separation and the transportation of photogenerated electrons and holes, thus improving the photocatalytic efficiency and the reaction kinetics of Li─O2 battery. Moreover, the FePc soluble photocatalysts induced the dual growth modes of surface growth and solution‐mediated growth pathways for the discharge products lead to an additional discharge capacity in the Li─O2 battery. Accordingly, the battery exhibits a lower overpotential of 0.33 V between discharge and charge plateaus at a current density of 0.01 mA cm−2, displaying the excellent cyclic stability (remaining a round‐trip efficiency of 81.1% after 130 cycles). The novel strategy provides new approaches for the construction of the light‐assisted Li─O2 batteries with reduced overpotential and boosted energy efficiency.

Published: August 2024

AbstractTumor‐specific microRNA (miRNA) imaging strategies are critical for investigating mechanisms associated with cancer progression; however, nonspecific signal leakage and false‐positive signaling limit their selectivity and efficiency. In this paper, an endogenously activated and self‐reinforced DNA lipid nanodevice (LND) for spatial‐specific and high‐contrast imaging of miRNAs in living cells and animals is presented. The LND is functionalized on cholesterol‐based lipid micelles (CLMs) containing smart response and self‐fueling DNA components that display redox‐activatable and autocatalytic miRNA probing activities, respectively. The LNDs are initially silenced and selectively activated using glutathione, an endogenous microenvironmental factor overexpressed in tumor cells, to prevent nonspecific signal leakage. Subsequently, an autocatalytic DNA circuit is used for tumor‐specific and high‐contrast miRNA imaging. It is demonstrated that robust CLM nanoparticles can be easily assembled from a cholesterol‐conjugated G‐rich DNA sequence by stirring in a buffered solution, enabling the LND to enter cells naturally. In addition, in vitro and in vivo data illustrate that the enhanced biostability of DNA components on the surface of LNDs can be realized for minimizing false‐positive signals, making the system ideal for miRNA imaging in living mice. This smart LND technique has great potential for precise biomedical imaging and clinical diagnosis.
