Some unsteady flow phenomena downstream of an axial compressor stage.
Creators: name: Lockhart, Robert Craig
Publisher: name: University Of Tasmania
Year: 2023

description: A detailed investigation of some unsteady flow phenomena occurring downstream of the rotor row in a single-stage, axial flow compressor, having three blade rows is described. Measurements of both unsteady , and mean flow properties in the vicinity of the stator row are presented. Experimental mean velocity distributions are compared with values from potential flow calculations and excellent agreement is obtained in areas outside viscous flow regions. A quasi-steady model based on the interaction of wakes from the inlet guide vane and rotor rows is used to explain a circumferential variation observed in the unsteady flow; this variation originates downstream of the rotor and continues undisturbed through the stator row. Specifically, this variation occurs in the decay of the rotor wake velocity defect and there is an associated circumferential variation in the apparent turbulence level and mean velocity downstream of the rotor. General unsteady flow phenomena occurring in the vicinity of the stator blades are examined with particular reference to the leading and trailing edge regions. Other work in the field of unsteady flow in axial turbomachinery is discussed.

description: We consider the effect of broadband decoherence on the performance of refocusing sequences, having in mind applications of dynamical decoupling in concatenation with quantum error correcting codes as the first stage of coherence protection. Specifically, we construct cumulant expansions of effective decoherence operators for a qubit driven by a pulse of a generic symmetric shape, and for several sequences of $π$- and $π/2$-pulses. While, in general, the performance of soft pulses in decoupling sequences in the presence of Markovian decoherence is worse than that of the ideal $δ$-pulses, it can be substantially improved by shaping.

Multiscale structural, thermal and thermo-structural optimization towards three-dimensional printable structures
Creators: name: Imediegwu, Chikwesiri Tolu
Publisher: name: Imperial College London
Year: 2020

description: This thesis develops a robust framework for the multiscale design of three-dimensional lattices with macroscopically tailored structural and thermal characteristics. The work exploits the high process flexibility and precision of additive manufacturing to the physical realization of complex microstructure of metamaterials by developing and implementing a multiscale approach. Structures derived from such metamaterials exhibit properties which differ from that of the constituent base material. Inspired by the concept of Free Material Optimization (FMO), a periodic microscale model is developed whose geometric parameterization enables smoothly changing properties and for which the connectivity of neighbouring microstructures in the large-scale domain is guaranteed by slowly changing large-scale descriptions of the lattice parameters. The microscale model is evaluated at full factorial design points to discretely populate material property spaces. A property point is fully defined for a micro-architecture when its elasticity matrix, thermal conductivity matrix and volume fraction is determined. The process of property-space population is facilitated by leveraging the existence of micro-architecture symmetries so that there exists a 95% reduction in the simulations required despite a full-factorial design of experiments. The discrete property evaluations are converted to continuous functions by response surface modelling so that the properties exist as continuous functions of the micro-architecture geometry parameters. A lattice-based functional grading of material is derived using the finite element method. The optimization is driven by a chain-rule combination of sensitivities derived by the adjoint method and sensitivities derived from explicit material property expressions. The novelty of the work lies in the use of multiple geometry-based small-scale design parameters for optimization problems in three-dimensional real space. The approach is demonstrated by solving structural, thermal and thermo-structural optimization problems. The results show designs with improved optimality compared to commonly implemented optimization methodologies. The optimal designs obtained are physically realizable by additive manufacturing techniques.
Enhancing cardiomyocyte survival from myocardial infarction with cardiac stromal cell-secreted factors
Creators: name: Constantinou, Chrystalla
Publisher: name: Imperial College London
Year: 2020

description: Myocardial infarction is the leading cause of death globally, and progression to heart failure is directly proportional to infarct size. Targeting cardiomyocyte loss is vital to stop cardiac damage. Previous data from our group show that intramyocardial injection of cardiac stromal cells (CSC) at time of infarct results in scar size reduction and improvement in ejection fraction. However, injected CSC are poorly retained, hence early paracrine signals might explain the observed improvement of cardiac function. Here we showed that injecting CSC-conditioned media into the mouse infarct border zone reduced apoptotic cardiomyocytes >70% locally. Subsequently, the paracrine effects of CSC were investigated, using human pluripotent stem cell-derived cardiomyocytes (hPSC-CM) as a target more relevant to translation. In co-culture and conditioned medium studies, the CSC secretome markedly inhibited human myocyte death, induced by three different cardiotoxic molecules; menadione, doxorubicin and imatinib. Follow-on studies were chiefly performed with menadione, showing preserved mitochondrial membrane depolarization and inhibited ROS generation in the presence of CSC-conditioned media. Functional assays revealed that calcium cycling and action potential generation were also preserved following CSC- conditioned medium treatment of menadione-stressed cells. Characterization studies on the protective secretome pointed to exosome-independent molecules, which were thermolabile and > 3 kDa in size. RNA-sequencing revealed that the CSC-secretome downregulated pro-apoptotic genes and preserved cardiac function and contractility markers in stressed hPSC-CM. A novel bioinformatic tool was used to predict the potential ligand-receptor interactions under conditions of cardiomyocyte stress. In terms of proteomics, cytokine arrays highlighted protein factors enriched in conditioned media from protective versus non-protective populations. Human CSC were also characterized and found to resemble mouse CSC in molecular signature, as well as in their paracrine protective ability. Thus, hPSC-CM provide an auspicious, relevant human platform to investigate extracellular signals for cardiac muscle survival, corroborating human cardioprotection by the CSC-secretome and supporting the further investigation of CSC-conditioned medium as a potential cell-free therapeutic product.
Generalized Lepton Number and Dark Left-Right Gauge Model

description: In a left-right gauge model of particle interactions, the left-handed fermion doublet (nu,e)_L is connected to its right-handed counterpart (n,e)_R through a scalar bidoublet so that e_L pairs with e_R, and nu_L with n_R to form mass terms. Suppose the latter link is severed without affecting the former, then n_R is not the mass partner of nu_L, and as we show in this paper, becomes a candidate for dark matter which is relevant for the recent PAMELA and ATIC observations. We accomplish this in a specific nonsupersymmetric model, where a generalized lepton number can be defined, so that n_R and W_R are odd under R = (-1)^{3B+L+2j}. Fermionic leptoquarks are also predicted.

title: Performing the Nation: Identity, Violence and The Search for Plurality in Bangladesh
Creators: name: Chakraborthy, Sudip
Publisher: name: Goldsmiths, University of London
Year: 2024

description: This research project examines the socio-political context that has generated the contest for national identity in Bangladesh since the War of Independence in 1971. By means of performance and Practice Research, the thesis examines the politics of identity in which the citizens of Bangladesh engage in daily life. It proposes how Practice Research via theatrical performance can provide a space for the acceptance of fluid and heterogeneous cultural identities in Bangladesh. If the “nation” is, as Ernest Renan argues, the possession in common of a rich legacy of memories, an on-going present-day consent, and a desire to live together, then the socio-political context of this study explores how religious, cultural and ethnic markers of national identity are imagined, contested and performed among and by various ethnic, religious, and cultural communities. The research is underpinned by “identity” as a notion that is unfixed, that is in constant flux, and that is informed by various and sometime contradictory social practices. This project explores how national identity in Bangladesh is anything but monolithic, and indeed is always-already in flux. The thesis seeks to understand identity in Bangladesh today by presenting the views of multiple contestants representing religious, cultural, and ethnic groups. Via interviews with different demographic groups, workshops discussing individual and community identities, and a devised theatrical performance (presented in filmed form owing to the COVID-19 pandemic), the project investigates how different individuals and communities can meet, play out, challenge, and respect their own and each other’s identities and specificities in the theatre space.
Measurement of the Inclusive ep Scattering Cross Section at Low Q^2 and x at HERA

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A measurement of the inclusive ep scattering cross section is presented in the region of low momentum transfers, 0.2 GeV^2 < Q^2 < 12 GeV^2, and low Bjorken x, 5x10^-6 < x < 0.02. The result is based on two data sets collected in dedicated runs by the H1 Collaboration at HERA at beam energies of 27.6 GeV and 920 GeV for positrons and protons, respectively. A combination with data previously published by H1 leads to a cross section measurement of a few percent accuracy. A kinematic reconstruction method exploiting radiative ep events extends the measurement to lower Q^2 and larger x. The data are compared with theoretical models which apply to the transition region from photoproduction to deep inelastic scattering.

Studies on some lipids of clinical interest
Creators: name: Mejglo, Zenon Antoni
Publisher: name: University Of Tasmania
Year: 2023

description: Chapter I reports studies on a number of common drugs and metabolites, some of which were found to affect lipids. Quantitative studies of drug‚ÄövÑvÆinduced release of cholesterol esters from lipoproteins in vitro are described. Tetracycline was found to act an both lipoproteins and proteins, causing marked denaturation of the latter and a strong delipidation of the former. Similar effects were noted in the cases of Atromid S and Phenformin. These drugs were also reacted with serum in combination with magnesium lactate alone, and in combination with pyridoxine, and in the latter case some enhancement of delipidating effects were seen. Similar tests on a number of amino acids were negative. Spectrophotometric, electrophoretic and immunoelectrophoretic investigations of the type and degree of binding of tetracycline and nitrofurantoin to serum proteins are reported in Chapter II. Competitive binding of tetracycline with displacement of lipids from their binding sites support the findings of Baer, Palmer Schmitt and Chargaff. Evidence is presented on competition between serum protein fractions for the denaturing drug. The main aim of the work described in Chapter III was to ascertain whether chemical features of serum sphingolipids are of diagnostic value. Quantitation of free ceramides showed that, while total serum ceramides (which correlate well with serum triglycerides) seldom vary beyond normal limits, fractions rich in hydroxy-acids indicate atherosclerotic risk. Such diagnostic data appear more reliable than indications from cholesterol assays. The free serum ceramides noted were assigned origins from sphingomyelin and glycosphingolipids respectively. A routine method for the assay of free serum ceramides has been developed; it is based on a thin‚ÄövÑvÆlayer chromatographic technique followed by densitometric scanning. The patterns of fatty acid moiety in diagnostically interesting free serum ceramides have been established by gas‚ÄövÑvÆliquid chromatography. The concomitant variation of base moieties appears of less practical interest.

description: Recent results from the PAMELA satellite indicate the presence of a large flux of positrons (relative to electrons) in the cosmic ray spectrum between approximately 10 and 100 GeV. As annihilating dark matter particles in many models are predicted to contribute to the cosmic ray positron spectrum in this energy range, a great deal of interest has resulted from this observation. Here, we consider pulsars (rapidly spinning, magnetized neutron stars) as an alternative source of this signal. After calculating the contribution to the cosmic ray positron and electron spectra from pulsars, we find that the spectrum observed by PAMELA could plausibly originate from such sources. In particular, a significant contribution is expected from the sum of all mature pulsars throughout the Milky Way, as well as from the most nearby mature pulsars (such as Geminga and B0656+14). The signal from nearby pulsars is expected to generate a small but significant dipole anisotropy in the cosmic ray electron spectrum, potentially providing a method by which the Fermi gamma-ray space telescope would be capable of discriminating between the pulsar and dark matter origins of the observed high energy positrons.

Polymorphism, sexual reproduction, meiosis and polyploidy and their implications for desmid taxonomy.
Creators: name: Ling, Hau U
Publisher: name: University Of Tasmania
Year: 2023

description: Conjugation and zygospore germination are described for 6 Pleurotaenium, 2 Micrasterias and 1 Staurastrum species. Probable chemotaxis is demonstrated in one Pleurotaenium species and selective mating, where a plus clone actively chooses one of two minus clones, Is shown to be common in the P. mamillatum complex. The Pleurotaenium species show remarkable homogeneity in conjugation features, possession of 5-walled smooth zygospores with operculate exospores and mammillate mesospores and producing single germination products. Zygospores of M. hardyi, A laticeps and St. orbiculare var. ralfsii are spiny, 3-walled, but only the Micrasterias zygospores are operculate. All three produce 2 germination products. Meiosis is described in germinating zygospores from crosses between various karyotypes and ploidy levels of the P. mamillatum complex, between haploids and diploids and morphologically different strains for other species of Pleurotaenium and the two Micrasterias species. In the Pleurotaenium species meiosis is chiasmate, conventional in character and the chromosomes have localized centromeres. Sexual crossing, resulting in viable, fertile offspring, occurs to a surprising degree between strains with widely disparate chromosome numbers, ploidy levels and geographical location. These strains form discrete groups that are reproductively isolated from one another. The implications that the results have for desmid taxonomy are discussed.
Proof of the combinatorial nullstellensatz over integral domains in the spirit of Kouba

description: It is shown that by eliminating duality theory of vector spaces from a recent proof of Kouba (O. Kouba, A duality based proof of the Combinatorial Nullstellensatz. Electron. J. Combin. 16 (2009), #N9) one obtains a direct proof of the nonvanishing-version of Alon's Combinatorial Nullstellensatz for polynomials over an arbitrary integral domain. The proof relies on Cramer's rule and Vandermonde's determinant to explicitly describe a map used by Kouba in terms of cofactors of a certain matrix. That the Combinatorial Nullstellensatz is true over integral domains is a well-known fact which is already contained in Alon's work and emphasized in recent articles of Michalek and Schauz; the sole purpose of the present note is to point out that not only is it not necessary to invoke duality of vector spaces, but by not doing so one easily obtains a more general result.

The ionospheric Z ray return mechanism
Creators: name: Hudspeth, JW
Publisher: name: University Of Tasmania
Year: 2023

description: Two alternative mechanisms, backscattering and tilt/wedge, for return of the ionospheric Z ray are examined. It is found that further experimental information is required in order to choose between them. Experimental tests of the mechanisms are proposed. The Llanherne HF radio-telescope was used as a narrow beam ionospheric sounder to obtain angle of arrival information on the 0, X and Z echoes. From the results of these experiments together with examination of h'f ionograms showing Z echoes it is concluded that neither mechanism satisfactorily explains the return of the Z echo in an. overwhelming majority of cases. A third mechanism is proposed which returns the Z ray by trapping in an ionospheric duct. This mechanism is able to explain many features of the Z echo and computer ra1 tracing of the model together with evidence from the existing literature suggests that this mechanism is the one operating in almost all cases of Z echo, except perhaps for those occurring at very high magnetic latitudes close to the Dip Pole.

description: We derive a general form of first-order flow equations for extremal and non-extremal, static, spherically symmetric black holes in theories with massless scalars and vectors coupled to gravity. By rewriting the action as a sum of squares a la Bogomol'nyi, we identify the function governing the first-order gradient flow, the `generalised superpotential', which reduces to the `fake superpotential' for non-supersymmetric extremal black holes and to the central charge for supersymmetric black holes. For theories whose scalar manifold is a symmetric space after a timelike dimensional reduction, we present the condition for the existence of a generalised superpotential. We provide examples to illustrate the formalism in four and five spacetime dimensions.

description: Emission from the 6.7 GHz methanol maser transition is very strong, is relatively stable, has small internal motions, and is observed toward numerous massive star-forming regions in the Galaxy. Our goal is to perform high-precision astrometry using this maser transition to obtain accurate distances to their host regions. Eight strong masers were observed during five epochs of VLBI observations with the European VLBI Network between 2006 June, and 2008 March. We report trigonometric parallaxes for five star-forming regions, with accuracies as good as $\sim22 \mathrmμ$as. Distances to these sources are $2.57^{+0.34}_{-0.27}$ kpc for ON 1, $0.776^{+0.104}_{-0.083}$ kpc for L 1206, $0.929^{+0.034}_{-0.033}$ kpc for L 1287, $2.38^{+0.13}_{-0.12}$ kpc for NGC 281-W, and $1.59^{+0.07}_{-0.06}$ kpc for S 255. The distances and proper motions yield the full space motions of the star-forming regions hosting the masers, and we find that these regions lag circular rotation on average by $\sim$17 km s$^{-1}$, a value comparable to those found recently by similar studies.

A superposition of a periodic drive in the driven vortex lattice causes distinct changes in these fluctuations. We propose that prior to onset of the peak effect there exist hithertofore unexplored regime of coherent dynamics, with unexpected behaviour in velocity fluctuations.

description: Motivated by possible extensions of the braneworld models with two branes, we investigate some consequences of a variable brane tension using the well established results on consistency conditions. By a slight modification of the usual stress-tensor used in order to derive the braneworld sum rules, we find out some important constraints obeyed by time dependent brane tensions. In particular it is shown that the tensions of two Randall-Sundrum like branes obeying, at the same time, an Eotvos law, aggravate the fine tuning problem. Also, it is shown that if the hidden brane tension obeys an Eotvos law, then the visible brane has a mixed behavior allowing a bouncing-like period at early times while it is dominated by an Eotvos law nowadays. To finalize, we discuss some qualitative characteristics which may arise in the scope of dynamical brane tensions, as anisotropic background and branons production.

description: Considering one of the fundamental notions of Bers' theory of pseudoanalytic functions the generating pair via an intertwining relation we introduce its generalization for biquaternionic equations corresponding to different first-order systems of mathematical physics with variable coefficients. We show that the knowledge of a generating set of solutions of a system allows one to obtain its different form analogous to the complex equation describing pseudoanalytic functions of the second kind and opens the way for new results and applications of pseudoanalytic function theory. As one of the examples the Maxwell system for an inhomogeneous medium is considered, and as one of the consequences of the introduced approach we find a relation between the time-dependent one-dimensional Maxwell system and hyperbolic pseudoanalytic functions and obtain an infinite system of solutions of the Maxwell system. Other considered examples are the system describing force-free magnetic fields and the Dirac system from relativistic quantum mechanics.
Biology and production of Nyctiphanes australis G.O. Sars, in the coastal waters of S.E. Tasmania
Creators: name: Hosie, Graham William
Publisher: name: University Of Tasmania
Year: 2023

description: The euphausiid Nyctiphanes australis forms an important component of the zooplankton biomass in south-eastern Tasmanian coastal waters, particularly in Storm Bay where the species exists in high densities throughout most of the year. During the warmer spring and summer months, the standing crop of N. australis often exceeded the total copepod biomass. Rapid growth occurred throughout the year, with females reaching sexual maturity after 3 to 4 months. The total life span of N. australis is unlikely to exceed one year. The intermoult period increased exponentially with increase in body length and weight.

We obtained a C-NOT gate process fidelity of 0.988 (0.980) for a two (three) qubit/resonator system under ideal conditions, and a fidelity of 0.903 for a two qubit/resonator system under the best, currently achieved, experimental conditions. In both cases, we found that "qubit leakage" to higher levels of the resonator causes a majority of the loss of fidelity, and that such leakage becomes more pronounced as decoherence effects increase.

I present a very brief review of what we know and what we would like to know about neutrino mass, mixing, and flavor change. I consider the interplay between neutrino physics and forthcoming information from the Large Hadron Collider. I comment on a decade's progress and offer some context for work that lies ahead.

Subjects: Architectural design

description: Bazaar is a socioeconomic hub and an essential element of urban development. The bazaar development of Dhaka started 400 years ago on the pre-Mughal period. Throughout time, the bazaars of Dhaka grew and evolved to meet the demand of urban dwellers. This case study focuses on various bazaars located at different points in Dhaka City. Townhall market, Neela market, Ghatpara Bazaar, and Uttara 12 no-sector bazaar are the primary sites for this study. After performing cross-sectional surveying, it was observed that most bazaars in Dhaka city are unplanned, lack proper drainage systems and ventilation, and most of them grew organically. Another finding of the study is local bazaars in Dhaka do not have any vendor space, which is a traditional style. This article discusses some proposals to improve the current scenario. Firstly, to change the zoning so that the area can come under one drainage system. Secondly introducing parking space and ventilation system. Finally, some ideas to make the bazaar more inviting so that more people can access it. These suggestions can bring a solution to this very concerning bazaar issues of Dhaka City.

description: In this paper we report on a tuneable few electron lateral triple quantum dot design. The quantum dot potentials are arranged in series. The device is aimed at studies of triple quantum dot properties where knowing the exact number of electrons is important as well as quantum information applications involving electron spin qubits. We demonstrate tuning strategies for achieving required resonant conditions such as quadruple points where all three quantum dots are on resonance. We find that in such a device resonant conditions at specific configurations are accompanied by novel charge transfer behaviour.

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: I give a brief overview of the effective theory for the Color Glass Condensate, which is the high-density gluonic matter which controls high-energy scattering in QCD in the vicinity of the unitarity limit. I concentrate on fundamental phenomena, like gluon saturation, unitarization, and geometric scaling, and the way how these are encoded in the formalism. I emphasize the importance of the next-to-leading order corrections, especially the running of the coupling, for both conceptual and phenomenological issues. I survey the implications of the CGC theory for the HERA physics and its phenomenological applications based on saturation models.

description: We analyze the dynamics of a single scalar field in Friedmann-Robertson-Walker universes with spatial curvature. We obtain the fixed point solutions which are shown to be late time attractors. In particular, we determine the corresponding scalar field potentials which correspond to these stable solutions. The analysis is quite general and incorporates expanding and contracting universes with both positive and negative scalar potentials. We demonstrate that the known power law, exponential, and de-Sitter solutions are certain limits of our general set of solutions.

Sikhs and the rebellion of 1857
Creators: name: Sara, Harkirpal Singh
Publisher: name: University of British Columbia
Year: 2011

description: This thesis investigates the relation of the Sikhs to the Indian rebellion of 1857. References to the Sikhs have invariably been made in the histories of the sepoy mutiny, but none of them, not even the celebrated Sepoy War of Sir John Kaye, tackles this problem in detail. As a result, the student of the mutiny at best gets from these histories disjointed, and often inadequately explained, impressions about the role of the Sikhs during the great upheaval. This thesis accordingly sets out to analyze the effects of the sepoy mutiny on the history of the Sikhs. I have examined four main aspects of the problem: (1) the annexation of the Sikh kingdom by the British in 1849 and conditions in the Punjab between annexation and the outbreak of the rebellion of 1857; (2) the actual help given by the Sikhs to the British during the rebellion; (3) the motives of the Sikhs for giving their help; and (4) the rewards of the Sikhs for supporting the British during the crisis of 1857. The Sikhs established their political ascendancy in the Punjab on the ruins of the Mughal empire. During the first two decades of the 19th century most of the twelve misls or confederacies of the Sikhs were conquered and united into one kingdom by Ranjit Singh. However, the timely protection given by the British in 1809 to the Sikh chiefs of the Cis-Sutlej checked Ranjit Singh's expansionist designs beyond the Sutlej River. During his lifetime Ranjit Singh wisely remained on friendly terms with the British, but after his death the factious intrigues of his successors and the Sikh army plunged the Sikh kingdom into hostilities with the British. The defeat of the Sikhs in the wars of 1845-46 and 1848-49 resulted in the annexation of their kingdom by the British. After annexation the British showed moderation in dealing with the Sikhs and did not degrade them to the position of a landless class. Meanwhile the Sikhs, resigned to their fate, quickly adapted themselves to the new institutions which were established in the Punjab between 1849 and 1857. But the indifference of the British toward the interests of the Sikhs, and the Government's policy of extending patronage to Hindustanis, hurt both their feelings and their interests. The rebellion of 1857 provided the Sikhs with a unique opportunity to secure a change of attitudes by the British. They seized that opportunity and gave every help to the British, whose military power they believed was unchallengeable. After the suppression of the mutiny the Sikhs received generous rewards from their rulers. They were also given the one reward that would satisfy them most--British indifference gave way to British interest in their welfare. My investigation of the problem leads me to the conclusion that the outbreak of the sepoy mutiny unexpectedly ushered in brighter days for the Sikhs and laid the foundation for their future growth and strength in the Punjab.

description: Macroautophagy (autophagy) is driven by the coordinated actions of core autophagy-related (Atg) proteins. Atg8, the core Atg protein generally considered acting most downstream, has recently been shown to interact with other core Atg proteins via their Atg8-family-interacting motifs (AIMs). However, the extent, functional consequence, and evolutionary conservation of such interactions remain inadequately understood. Here, we show that, in the fission yeast Schizosaccharomyces pombe, Atg38, a subunit of the phosphatidylinositol 3-kinase (PtdIns3K) complex I, interacts with Atg8 via an AIM, which is highly conserved in Atg38 proteins of fission yeast species, but not conserved in Atg38 proteins of other species. This interaction recruits Atg38 to Atg8 on the phagophore assembly site (PAS) and consequently enhances PAS accumulation of the PtdIns3K complex I and Atg proteins acting downstream of the PtdIns3K complex I, including Atg8. The disruption of the Atg38-Atg8 interaction leads to the reduction of autophagosome size and autophagic flux. Remarkably, the loss of this interaction can be compensated by an artificial Atg14-Atg8 interaction. Our findings demonstrate that the Atg38-Atg8 interaction in fission yeast establishes a positive feedback loop between Atg8 and the PtdIns3K complex I to promote efficient autophagosome formation, underscore the prevalence and diversity of AIM-mediated connections within the autophagic machinery, and reveal unforeseen flexibility of such connections.
