description: Survivorship bias is the tendency to concentrate on the positive outcomes of a selection process and overlook the results that generate negative outcomes. We observe that this bias could be present in the popular MS MARCO dataset, given that annotators could not find answers to 38--45% of the queries, leading to these queries being discarded in training and evaluation processes. Although we find that some discarded queries in MS MARCO are ill-defined or otherwise unanswerable, many are valid questions that could be answered had the collection been annotated more completely (around two thirds using modern ranking techniques). This survivability problem distorts the MS MARCO collection in several ways. We find that it affects the natural distribution of queries in terms of the type of information needed. When used for evaluation, we find that the bias likely yields a significant distortion of the absolute performance scores observed. Finally, given that MS MARCO is frequently used for model training, we train models based on subsets of MS MARCO that simulates more survivorship bias. We find that models trained in this setting are up to 9.9% worse when evaluated on versions of the dataset with more complete annotations, and up to 3.5% worse at zero-shot transfer. Our findings are complementary to other recent suggestions for further annotation of MS MARCO, but with a focus on discarded queries. Code and data for reproducing the results of this paper are available in an online appendix.

description: The northeast continental shelf of New Zealand and adjacent Hauraki Gulf were surveyed from early spring to late summer, to identify biogeographic and trophic factors influencing mesozooplankton community distribution and abundance. The outer shelf supported low-abundance oceanic species associated with the East Auckland Current which were also transported to the inner shelf during upwelling. Outer gulf sites, where gulf and shelf waters converged, supported a characteristic frontal assemblage. The inner gulf supported an abundant and diverse neritic community, with greater seasonal variability than offshore. Over spring to summer, succession of mesozooplankton taxa reflected an ecosystem shift from net autotrophic to heterotrophic states. These biogeographic and trophic effects defined the grazing impact mesozooplankton had on lower trophic levels, with grazing often matching primary production in spring and early summer. Greater mesozooplankton abundances in the gulf were supported by higher volume-specific primary productivity than on the shelf. The results have important implications for higher trophic levels, including larval fish survival, adult fish distributions and whale feeding.

description: Par ce mémoire, j'ai souhaité étudier en profondeur la notion de nombres décimaux grâce à la littérature et voir comment ils sont enseignés en classe avec des entretiens de deux professionnels de l'enseignement. Le but a été de comprendre comment les élèves conçoivent ces nombres qu'ils commencent à travailler en 7ème année. Le résultat est sans appel : des difficultés récurrentes sont présentes chez les élèves et les méthodes d'enseignement y sont liées. Plutôt que de suivre aveuglément un MER qui a été rédigé depuis longtemps et de travailler presque exclusivement avec l'écriture décimale, il semble que de débuter un enseignement de ces nombres avec l'écriture fractionnaire soit plus adapté, car cela permet aux élèves de construire davantage de sens, alors qu'avec l'écriture décimale, de nombreux élèves appliquent des « trucs » qui marchent mais ils ne savent pas vraiment pourquoi. C'est en faisant des liens (en rencontrant les nombres sous diverses formes et avec diverses utilités) que les élèves peuvent construire du sens. C'est sans doute un des plus grands défis de l'école : donner du sens aux apprentissages. Et ce particulièrement en mathématiques qui sont souvent perçues comme abstraites et déconnectées du monde réel.

description: Increasing the resolution of image sensors has been a never ending struggle since many years. In this paper, we propose a novel image sensor layout which allows for the acquisition of images at a higher resolution and improved quality. For this, the image sensor makes use of non-regular sampling which reduces the impact of aliasing. Therewith, it allows for capturing details which would not be possible with state-of-the-art sensors of the same number of pixels. The non-regular sampling is achieved by rotating prototype pixel cells in a non-regular fashion. As not the whole area of the pixel cell is sensitive to light, a non-regular spatial integration of the incident light is obtained. Based on the sensor output data, a high-resolution image can be reconstructed by performing a deconvolution with respect to the integration area and an extrapolation of the information to the insensitive regions of the pixels. To solve this challenging task, we introduce a novel joint sparse deconvolution and extrapolation algorithm. The union of non-regular sampling and the proposed reconstruction allows for achieving a higher resolution and therewith an improved imaging quality.

description: Spin related phenomena play an important role in quantum physics. In this dissertation, we look into the spin dynamics of both nuclear and electron spins. Recently, physicists achieved considerable progress in understanding non-abelian and topological matter. Some feasible breeding ground for experimental observation of these phenomena are quantum Hall effect settings and structures with topological insulators. We therefore are interested in role of electron and nuclear spins in transport phenomena in these systems.We briefly introduce the subject of integer and fractional quantum Hall effect and topological insulators and discuss relevant mathematical methods such as K-matrix theory and quantum kinetic theory in Chapter 1. We also discuss Majorana Fermions, parafermions and Fibonacci anyons.In Chapter 2, we discuss interaction between nuclear spins and quantum Hall edge state electron spins via hyperfine interaction. In particular, we consider an experimental setting developed in prof. Rokhinson group, that studied a quantum device built to explore the possibility of creating parafermion zero modes. We used a simplified model with $k=\frac{1}{3}$ Luttinger Liquid counter propagating opposite spin edge states interacting with nuclear spins, and considered the polarization of nuclear spins caused by electric current flow and studied its dependence on bias and temperature. We also performed an renormalization group analysis of the hyperfine interaction. We evaluated the effects of Overhauser field generated by polarized nuclear spins on polarized and unpolarized FQH phases, and suggested a novel dynamical nuclear polarization mechanism, in which the polarization is not only spread by dipole-dipole interaction but also dynamically shifts the boundary between polarized and unpolarized phases. We further discussed the obstacles for observation of parafermion zero modes due to nuclear spins and proposed possible remedies.In chapter 3, we discuss the role of electron spins in the magneto-chiral anisotropy of resistance. We propose that polarization and relaxation of electron spins in quantum wells with spin-orbit interactions or on the surface state of a topological insulator under external magnetic field $B$ can induce an electric current that is quadratic in electric and linear in magnetic field resulting in non-reciprocity of resistance. We used the kinetic equation to analyze this mechanism.

Telling someone else's story : the life history of Alexander Donald (Pwerle) Ross (1915-1999)
Creators: name: Whitebeach, Terry
Publisher: name: Charles Darwin University
Year: 2006

description: This thesis is focused on the life history of Alexander Donald Ross, a Kaytetye senior man, of both Kaytetye and European ancestry, jointly authored by Alexander Donald (Don) Ross and Terry Whitebeach, a Tasmanian writer with European and Aboriginal family connections. Don Ross was born in 1915, approximately half a century after the first contact between Europeans and Aboriginals in the Northern Territory, and worked most of his life in the developing Northern Territory pastoral industry. He owned a cattle station, Neutral Junction Station, near the Barrow Creek Telegraph Station, on Kaytetye land, in Central Australia, between 1947 and 1952. During a lifetime spanning most of the twentieth century (he passed away in April 1999) Don Ross’s life was influenced greatly by changes in the pastoral industry and by social and political changes related to the rights of Indigenous people, which affected both the family lives and the employment conditions of Indigenous pastoral workers in the Northern Territory and throughout Australia. The thesis employs Don Ross’s narratives of his childhood, relationships and working life, which were compiled from interviews and conversations with a series of people (including the author of this thesis) to explore aspects of the period and region in which he lived. Relevant archival and other historical material is also employed as part of this investigation of the ‘life and times’ of Don Ross. Two significant aspects of Don Ross’s life, his skill as a stockman, and his ambiguous legal and social status as a man of both European and Kaytetye parentage, and the concomitant limits and freedoms his classification as ‘half-caste’ awarded him during different decades of the twentieth century, are crucial to this investigation. The thesis also investigates the processes whereby a life history is mediated through, and affected by, the perceptions and cultural position/s of the researcher, writer and receiver of the story, the perspectives revealed in the historical documents and records of the time, and successive interpretations of this material. Thus, it addresses the complex and contested historical, historiographical, literary, cultural and cross-cultural and personal processes of receiving, researching, compiling and narrating, from another time and place, and through the multifaceted lenses of memory and history, another person's life history; the implications and responsibilities of telling someone else’s story.

description: Dipeptidyl peptidase-III is an important enkephalin degrading enzyme and its inhibitors are expected to be promising in pain management. Some of its inhibitors showed an antinociceptive potential. The present study investigated the evaluation of dietary proteins as potential precursors of dipeptidyl peptidase-III inhibitors by measuring occurrence frequency of dipeptidyl peptidase-III inhibitory peptides. In silico analysis of 69 proteins from 17 food commodities revealed 2659 dipeptidyl peptidase-III inhibitory peptides. β-subunit of hemoglobin and annexin A5 of chicken showed highest dipeptidyl peptidase-III inhibiting potential followed by 12S seed storage globulin 2 of oat, β-conglycinin of soyabean, α-lactalbumin of cow milk, cruciferin CRU4 of rapeseed, and zein-alpha of maize But overall occurrence frequency of dipeptidyl peptidase-III inhibitory peptides was observed highest in maize followed by pumpkin, soyabean, and rapeseed, whereas barley showed the lowest frequency among plant based foods. Chicken and maize had the highest dipeptidyl peptidase-III inhibitory potential in animal and plant derived foods respectively, thus may serve as a natural dietary source for pain modulation.

description: In this article, novel joint semiparametric spline-based modeling of conditional mean and volatility of financial time series is proposed and evaluated on daily stock return data. The modeling includes functions of lagged response variables and time as predictors. The latter can be viewed as a proxy for omitted economic variables contributing to the underlying dynamics. The conditional mean model is additive. The conditional volatility model is multiplicative and linearized with a logarithmic transformation. In addition, a cube-root power transformation is employed to symmetrize the lagged response variables. Using cubic splines, the model can be written as a multiple linear regression, thereby allowing predictions to be obtained in a simple manner. As outliers are often present in financial data, reliable estimation of the model parameters is achieved by trimmed least-square (TLS) estimation for which a reasonable amount of trimming is suggested. To obtain a parsimonious specification of the model, a new model selection criterion corresponding to TLS is derived. Moreover, the (three-parameter) generalized gamma distribution is identified as suitable for the absolute multiplicative errors and shown to work well for predictions and also for the calculation of quantiles, which is important to determine the value at risk. All model choices are motivated by a detailed analysis of IBM, HP, and SAP daily returns. The prediction performance is compared to the classical generalized autoregressive conditional heteroskedasticity (GARCH) and asymmetric power GARCH (APGARCH) models as well as to a nonstationary time-trend volatility model. The results suggest that the proposed model may possess a high predictive power for future conditional volatility. Supplementary materials for this article are available online.

description: Even though image signals are typically defined on a regular two-dimensional grid, there also exist many scenarios where this is not the case and the amplitude of the image signal only is available for a non-regular subset of pixel positions. In such a case, a resampling of the image to a regular grid has to be carried out. This is necessary since almost all algorithms and technologies for processing, transmitting or displaying image signals rely on the samples being available on a regular grid. Thus, it is of great importance to reconstruct the image on this regular grid so that the reconstruction comes closest to the case that the signal has been originally acquired on the regular grid. In this paper, Frequency Selective Reconstruction is introduced for solving this challenging task. This algorithm reconstructs image signals by exploiting the property that small areas of images can be represented sparsely in the Fourier domain. By further taking into account the basic properties of the Optical Transfer Function of imaging systems, a sparse model of the signal is iteratively generated. In doing so, the proposed algorithm is able to achieve a very high reconstruction quality, in terms of PSNR and SSIM as well as in terms of visual quality. Simulation results show that the proposed algorithm is able to outperform state-of-the-art reconstruction algorithms and gains of more than 1 dB PSNR are possible.

description: Xylulose 5-phosphate/fructose 6-phosphate phosphoketolase (Xfp) is a key enzyme in the central carbohydrate metabolism in heterofermentative bacteria, in which enzymatic property of Xfps is well characterized. This is not the case in other microbes. The cyanobacterium Anabaena sp. PCC 7120 possesses three putative genes encoding Xfp, all1483, all2567, and alr1850. We purified three putative Xfps as recombinant proteins. The results of gel filtration indicated that these proteins form homomultimer complex. All1483 and All2567 showed phosphoketolase activity, whereas Alr1850 did not show the activity. Kinetic analyses demonstrated that substrates, fructose 6-phosphate and inorganic phosphate, are cooperatively bound to enzymes positively and negatively, respectively.

description: During transmission of video data over error-prone channels the risk of getting severe image distortions due to transmission errors is ubiquitous. To deal with image distortions at decoder side, error concealment is applied. This article presents Motion Compensated Three-Dimensional Frequency Selective Extrapolation, a novel spatio-temporal error concealment algorithm. The algorithm uses fractional-pel motion estimation and compensation as initial step, being followed by the generation of a model of the distorted signal. The model generation is conducted by an enhanced version of Three-Dimensional Frequency Selective Extrapolation, an existing error concealment algorithm. Compared to this existent algorithm, the proposed one yields an improvement in concealment quality of up to 1.64 dB PSNR. Altogether, the incorporation of motion compensation and the improved model generation extends the already high extrapolation quality of the underlying Frequency Selective Extrapolation, resulting in a gain of more than 3 dB compared to other well-known error concealment algorithms.

Global epidemiology, prevention and control of rheumatic heart disease with a focus on the Pacific Islands region
Creators: name: Colquhoun, Samantha Margaret
Publisher: name: Charles Darwin University
Year: 2015

description: Rheumatic heart disease (RHD) is a leading cause of cardiac disease among children in developing nations and Indigenous populations in some industrialised countries. In 1990, there were 29,172,383 prevalent cases of RHD globally, which increased to 34,232,795 in 2010, with 8,593,116 deaths during this entire period. Mortality due to RHD in Australia disproportionately affects young Indigenous people, with deaths due to RHD 43.1 times more common among young Indigenous people than the general population. Despite this, accurate documentation of the burden of RHD, particularly mortality, is lacking in many high-risk countries, and regional and global estimates of the disease require updating. In response, four studies were undertaken with the following aims: 1. to determine the prevalence of RHD in Fiji using echocardiography 2. to investigate the training of nurses in basic echocardiography to detect RHD 3. to estimate the global burden of RHD 4. to determine the mortality of RHD among Indigenous Australians. The prevalence of RHD in 1,666 school-aged children in Fiji was measured using echocardiography. It was found to be high when using World Health Organization criteria (7.2 cases per 1,000), and higher when using the new World Heart Federation criteria (8.4 per 1,000). Two nurses trained in basic RHD echocardiography in Fiji had high sensitivity to detect RHD (83% and 100%). The Global Burden of Disease Study estimates of RHD outlined in this thesis suggest a higher burden than previously reported, and support the contention that morbidity and mortality due to RHD have been underestimated globally. However, more robust epidemiologic data, such as those from Fiji and Indigenous Australia, are required to better inform these estimates. Novel approaches, such as the training of nurses in echocardiography, may enhance data collection in resource-poor settings. Better data will enhance advocacy to bring RHD control to those most in need.

description: Software projects use Issue Tracking Systems (ITS) like JIRA to track issues and organize the workflows around them. Issues are often inter-connected via different links such as the default JIRA link types Duplicate, Relate, Block, or Subtask. While previous research has mostly focused on analyzing and predicting duplication links, this work aims at understanding the various other link types, their prevalence, and characteristics towards a more reliable link type prediction. For this, we studied 607,208 links connecting 698,790 issues in 15 public JIRA repositories. Besides the default types, the custom types Depend, Incorporate, Split, and Cause were also common. We manually grouped all 75 link types used in the repositories into five general categories: General Relation, Duplication, Composition, Temporal / Causal, and Workflow. Comparing the structures of the corresponding graphs, we observed several trends. For instance, Duplication links tend to represent simpler issue graphs often with two components and Composition links present the highest amount of hierarchical tree structures (97.7%). Surprisingly, General Relation links have a significantly higher transitivity score than Duplication and Temporal / Causal links. Motivated by the differences between the link types and by their popularity, we evaluated the robustness of two state-of-the-art duplicate detection approaches from the literature on the JIRA dataset. We found that current deep-learning approaches confuse between Duplication and other links in almost all repositories. On average, the classification accuracy dropped by 6% for one approach and 12% for the other. Extending the training sets with other link types seems to partly solve this issue. We discuss our findings and their implications for research and practice.

description: Epicardial adipose tissue is a type of adipose tissue located between the heart wall and a protective layer around the heart called the pericardium. The volume and thickness of epicardial adipose tissue are linked to various cardiovascular diseases. It is shown to be an independent cardiovascular disease risk factor. Fully automatic and reliable measurements of epicardial adipose tissue from CT scans could provide better disease risk assessment and enable the processing of large CT image data sets for a systemic epicardial adipose tissue study. This paper proposes a method for fully automatic semantic segmentation of epicardial adipose tissue from CT images using a deep neural network. The proposed network uses a U-Net-based architecture with slice depth information embedded in the input image to segment a pericardium region of interest, which is used to obtain an epicardial adipose tissue segmentation. Image augmentation is used to increase model robustness. Cross-validation of the proposed method yields a Dice score of 0.86 on the CT scans of 20 patients.

description: A sensitive and simple method has been established for simultaneous preconcentration of trace amounts of Pb (II) and Ni (II) ions in water samples prior to their determination by flame atomic absorption spectrometry. This method was based on the using of a micro-column filled with graphene oxide as an adsorbent. The influences of various analytical parameters such as solution pH, adsorbent amount, eluent type and volume, flow rates of sample and eluent, and matrix ions on the recoveries of the metal ions were investigated. Using the optimum conditions, the calibration graphs were linear in the range of 7–260 and 5–85 μg L−1 with detection limits (3Sb) of 2.1 and 1.4 μg L−1 for lead and nickel ions, respectively. The relative standard deviation for 10 replicate determinations of 50 μg L−1 of lead and nickel ions were 4.1% and 3.8%, respectively. The preconcentration factors were 102.5 and 95 for lead and nickel ions, respectively. The adsorption capacity of the adsorbent was also determined. The method was successfully applied to determine the trace amounts of Pb (II) and Ni (II) ions in real water samples. The validation of the method was also performed by the standard reference material.

description: The complexity of digital embedded systems has been increasing in different safety-critical applications such as industrial automation, process control, transportation, and medical digital devices. The correct operation of these systems relies too heavily on the behavior of the embedded digital device. As a result, any mistake or error made during the design stage of the embedded device can change the overall functionality of the critical system and cause catastrophic consequences. To detect these errors and eliminate their effects on the system, new error detection approaches must be innovated and used in the design of the digital system. However, these methods require enormous costs and time. One of these methods being employed to solve this issue is called Verification and Validation (V&V) which confirms that the system behavior meets the requirements early in the development process, before moving on to the implementation phase. Because of their benefits and importance in the building of complex digital systems, the employment of formal V&V methods has recently attracted a lot of attention. This paper focuses on presenting various studies on formal verification approaches and how the V&V can be achieved for developing high dependable digital embedded systems

description: This article considers the problem of asymmetric comparisons, that is, instances where one treatment serves as the compelling standard treatment for a certain disease or health condition, where the asymmetric comparisons are performed in terms of the Poisson rates. We propose asymptotic Wald-type tests and confidence intervals suitable for demonstrating superiority and noninferiority for a given margin. The testing methods for the difference and ratio are based on the unconstrained (MLE) and constrained (CMLE) maximum likelihood estimator. The resulting CMLE-based tests for asymmetric comparisons are equivalent to the standard (i.e., those for symmetric comparisons) CMLE-based tests. The asymmetric tests as well as the standard MLE-based tests are evaluated via simulations. The CMLE-based asymmetric tests are shown to adequately control the Type I error in most settings, while the MLE-based asymmetric tests are shown to have this property only in settings with relatively large sample sizes and means. In all settings, the MLE-based asymmetric tests are more powerful than both the asymmetric CMLE-based and the standard MLE-based tests. We also propose asymptotic confidence intervals that can be used to estimate the difference or ratio of the two rates (the presentation of this content includes supplementary material that is available online), and discuss how power and sample size estimation can be done to aid in study planning. Supplementary materials for this article are available online.

description: Code summarization with deep learning has been widely studied in recent years. Current deep learning models for code summarization generally follow the principle in neural machine translation and adopt the encoder-decoder framework, where the encoder learns the semantic representations from source code and the decoder transforms the learnt representations into human-readable text that describes the functionality of code snippets. Despite they achieve the new state-of-the-art performance, we notice that current models often either generate less fluent summaries, or fail to capture the core functionality, since they usually focus on a single type of code representations. As such we propose GypSum, a new deep learning model that learns hybrid representations using graph attention neural networks and a pre-trained programming and natural language model. We introduce particular edges related to the control flow of a code snippet into the abstract syntax tree for graph construction, and design two encoders to learn from the graph and the token sequence of source code, respectively. We modify the encoder-decoder sublayer in the Transformer's decoder to fuse the representations and propose a dual-copy mechanism to facilitate summary generation. Experimental results demonstrate the superior performance of GypSum over existing code summarization models.

description: The saturated liquid line of the systems nitrogen (N2) + diethyl ether and N2 + 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone (Novec 649) is measured along three isotherms, that is, 390, 420, and 450 K and 360, 390, and 420 K, respectively. The employed gas solubility apparatus, based on the synthetic method, allows to measure points up to the critical region of these mixtures. The experimental data are used to correlate the Peng–Robinson and PC-SAFT equations of state (EOS). For the parametrization of the system, N2 + diethyl ether the Peng–Robinson EOS is combined with the Huron–Vidal mixing rule and the non-random two-liquid (NRTL) excess Gibbs energy model; for the system N2 + Novec 649 the quadratic mixing rule is used.

Dynamic Resource Assignment

description: The aim of this report is to study containers resource isolation and explore Dynamic Resource
Assignment techniques to maximize hardware utilization. Containers bring virtualization benefits to
High-Performance Computing systems, thus allowing the safe execution of concurrent applications
within the same computational node. In this situation it becomes possible to dynamically re-assign
resources of multiples applications given their workload, maximizing the useful time the hardware is
being used. Nevertheless, containers do not fully isolate their environment from the host, so full
isolation is not guaranteed. This report designs, implements and functionally evaluates the workload
collocation concept applying dynamic resource assignment solutions for containers.

description: Les élèves allophones, sont-ils source de stress pour les enseignants d’aujourd’hui ? Comment gérer la multi culturalité et l’hétérogénéité des classes actuelles ? Les enseignants, sont-ils prêts à relever ce défi professionnel ? Dans quelle mesure ont-ils été préparés à la gestion des élèves allophones ? Comment perçoivent-ils cette situation ? L’allophonie est-elle considérée comme une richesse ou comme un problème dans les classes vaudoises ? C’est à cette problématique due au taux élevé d’étrangers dans les classes que ce mémoire tente de donner une réponse. Trois facteurs seront mis en relation : la gestion quotidienne des élèves allophones, le stress du corps enseignant et la formation reçue par les enseignants. Nous essayerons d’établir les éventuels liens entre ces trois facteurs : est-ce que le stress des enseignants est dû à la présence de ces élèves allophones ou est-ce plutôt le fait d’avoir des classes si hétérogènes, ou se côtoient toutes sortes d’élèves à besoins particuliers ? Est-ce le fait que l’élève allophone ne parle pas ou très peu le français qui peut stresser l’enseignant où est-ce plutôt le contexte global de l’élève : différence de culture, de mentalité, d’habitudes, de traditions… Nous avons constaté une certaine frustration de la part des enseignantes qui aimeraient avoir le temps et les moyens pour mieux intégrer ses élèves et qui sont, d’autre part, souvent submergées par des sollicitations administratives de plus en plus nombreuses. Il semble que ce ne soit pas tant l’élève allophone en lui-même ce qui peut être une source de stress pour les enseignants mais plutôt la difficulté à gérer des classes de plus en plus hétérogènes. Le décalage entre les visées intégratives de notre canton et les moyens mis à disposition dans les établissements scolaires causent une certaine tension parmi les enseignants. C’est ce défi de la cohérence qu’il faudrait relever afin de trouver de nouvelles pistes de résolution.

description: We study the simultaneous occurrence of long memory and nonlinear effects, such as parameter changes and threshold effects, in time series models and apply our modeling framework to daily realized measures of integrated variance. We develop asymptotic theory for parameter estimation and propose two model-building procedures. The methodology is applied to stocks of the Dow Jones Industrial Average during the period 2000 to 2009. We find strong evidence of nonlinear effects in financial volatility. An out-of-sample analysis shows that modeling these effects can improve forecast performance. Supplementary materials for this article are available online.

description: Xylulose 5-phosphate/fructose 6-phosphate phosphoketolase (Xfp) is a key enzyme in the central carbohydrate metabolism in heterofermentative bacteria, in which enzymatic property of Xfps is well characterized. This is not the case in other microbes. The cyanobacterium Anabaena sp. PCC 7120 possesses three putative genes encoding Xfp, all1483, all2567, and alr1850. We purified three putative Xfps as recombinant proteins. The results of gel filtration indicated that these proteins form homomultimer complex. All1483 and All2567 showed phosphoketolase activity, whereas Alr1850 did not show the activity. Kinetic analyses demonstrated that substrates, fructose 6-phosphate and inorganic phosphate, are cooperatively bound to enzymes positively and negatively, respectively.
