description: Ischemic nephropathy is an emerging cause of end stage renal disease, associated with many co-morbidities especially cardiovascular disease risk and derangement in calcium-phosphorus homeostasis resulting in hyperphosphatemia, influencing bones, a characteristic of advancing chronic kidney disease. The management of elevated serum phosphorus has been a challenge in this patient population with compromised kidney performance, as available phosphorus lowering agents possess many undesirable hazardous secondary effects and/or are very expensive. While niacin in different formulation is known to not only correct dyslipidemia but also reduce phosphorus level, but its clinical use restricted owing to side effects. The objective of present study is to evaluate such effect of niacin extended release (NER) in ischemic nephropathy. The chronic kidney disease patients fulfilling the pre-defined criteria were randomly categorized into two groups of equal size (n=60) and prescribed either atorvastatin 20 mg/day or NER 500 mg/day with the same dose of statin for four months. A control of 50 healthy characters matched was also incorporated for local reference range. Baseline and follow up phosphorus concentration was measured and means were compared using t-test at SPSS version 17 with 0.05 chosen alpha. There was no difference in the baseline levels in both groups while significant (p<0.001) hyperphosphatemia was observed in both units as compared with healthy controls. The administration of atorvastatin alone for four weeks showed an insignificant decrease in phosphorus, whereas, NER significantly reduced phosphorus (p<0.001). The mean percent change from baseline to follow up further endorsed the finding as statin alone brought -13.8 % reduction in phosphorus and NER -47 % from baseline. NER, at its lowest prescribed dose once a day was well tolerated by most of the patients and demonstrated significant goal achievement of phosphorus reduction. It is concluded that NER even at low doses in renal compromised dyslipidemic patients may be a promising approach to prevent the harmful vascular, valvular effects caused by hyperphosphatemia in addition to its principal target of HDL-C elevation.

description: It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]FFDG PET image data. The existing models employ multiple parameters for feature extraction which makes it difficult to implement in clinical settings for the quantitative characterization. This article reports an easy-to-use and differential SUV based model for quantitative assessment of the intratumor heterogeneity from 3D [18]FFDG PET image data. An H index is defined to assess tumor heterogeneity by summing voxel-wise distribution of differential SUV from the [18]F-FDG PET image data. The summation is weighted by the distance of SUV difference among neighboring voxels from the center of the tumor and can thus yield increased values for tumors with peripheral sub-regions of high SUV that often serves as an indicator of augmented malignancy. Furthermore, the sign of H index is used to differentiate the rate of change for volume averaged SUV from its center to periphery. The new model with the H index has been compared with a widely-used model of gray level cooccurrence matrix (GLCM) for image texture characterization with phantoms of different configurations and the [18]F-FDG PET image data of 6 lung cancer patients to evaluate its effectiveness and feasibility for clinical uses. The comparison of the H index and GLCM parameters with the phantoms demonstrate that the H index can characterize the SUV heterogeneity in all of 6 2D phantoms while only 1 GLCM parameter can do for 1 and fail to differentiate for other 2D phantoms. For the 8 3D phantoms, the H index can clearly differentiate all of them while the 4 GLCM parameters provide complicated patterns in the characterization. Feasibility study with the PET image data from 6 lung cancer patients show that the H index provides an effective single-parameter metric to characterize tumor heterogeneity in terms of the local SUV variation, and it has higher correlation with tumor volume change after radiotherapy (R2 = 0.83) than the 4 GLCM parameters (R2 = 0.63, 0.73, 0.59 and 0.75 for Energy, Contrast, Local Homogeneity and Entropy respectively). The new model of the H index has the capacity to characterize the intratumor heterogeneity feature from 3D [18]F-FDG PET image data. As a single parameter with an intuitive definition, the H index offers potential for clinical applications.

description: The roles of GABAergic receptors of the Basolateral amygdala (BLA) in the cannabinoid CB1 receptor agonist (arachydonilcyclopropylamide; ACPA)-induced anxiolytic-like effect and aversive memory deficit in adult male mice were examined in elevated plus-maze task. Results showed that pre-test intra-peritoneal injection of ACPA induced anxiolytic-like effect (at dose of 0.05 mg/kg) and aversive memory deficit (at doses of 0.025 and 0.05 mg/kg). The results revealed that Pre-test intra-BLA infusion of muscimol (GABAA receptor agonist; at doses of 0.1 and 0.2 µg/mouse) or bicuculline (GABAA receptor antagonist; at all doses) impaired and did not alter aversive memory, respectively. All previous GABA agents did not have any effects on anxiety-like behaviors. Interestingly, pretreatment with a sub-threshold dose of muscimol (0.025 µg/mouse) and bicuculline (0.025 µg/mouse) did not alter anxiolytic-like behaviors induced by ACPA, while both drugs restored ACPA-induced amnesia. Moreover, muscimol or bicuculline increased and decreased ACPA-induced locomotor activity, respectively. Finally the data may indicate that BLA GABAA receptors have critical and different roles in anxiolytic-like effect, aversive memory deficit and locomotor activity induced by ACPA.

Claiming the land : Indians, goldseekers, and the rush to British Columbia
Creators: name: Marshall, Daniel Patrick
Publisher: name: University of British Columbia
Year: 2009

description: During the Fraser River gold rush of 1858, over 30,000 goldseekers invaded the Aboriginal lands of southern British Columbia, setting off Native-White conflicts similar to the Indian Wars of the American Pacific Northwest. Prior to the establishment of the Colony of British Columbia, 19 November 1858, British sovereignty was marginal and the Fraser gold fields clearly an extension of the American West. The Native world was not defined by the 49th parallel, nor the kind of violence that crossed the international border with the expansion of the California mining frontier. These goldseekers, in prosecuting military-like campaigns, engaged in significant battles with First Nations, broke the back of full-scale Native resistance in both southern British Columbia and eastern Washington State, and brokered Treaties of Peace on foreign soil. The very roots of Native sovereignty, rights and unrest, current in the province today, may be traced to the 1858 gold rush. This dissertation maintains that British Columbia's 'founding' event has not been explored due to the transboundary nature of the subject. It has little or no presence in Canadian historiography as presently written. The year 1858 represents a period of exceptional flux and population mobility within an ill-defined space. I argue that the key to the Fraser Rush is to be found south of the border: in geographic space (the Pacific Slope) and in place (California mining frontier). It examines the three principal cultures that inhabited the middle ground of the gold fields, those of the Fur Trade (Hudson's Bay Company and Native), Californian, and British world views. The year 1858 represents a power struggle on the frontier: a struggle of local Indian power, the entrance of an overwhelming outsiders' power, transplanted locally and directed largely from California, and regional and long-distance British power. It is a clash of two "frontier" creations: that of "California culture" and "fur trade culture" that not only produced violence but the formal inauguration of colonialism, Indian reserves, and ultimately the expansion of Canada to the Pacific Slope.

description: Agricultural policy support to farmers is being reconsidered in most industrialized countries. The adverse incentive structure of price support is generally considered to be inadequate. Income support schemes may therefore be preferable in view of externalities of agricultural production such as the development and maintenance of nature. A plethora of studies comprises estimates of the impact of a sustained future benefit stream (among other things through continued price and income support) on land prices. The empirical results of these studies vary considerably. We apply meta-analytical methods to identify the factors explaining this variation in capitalization of future benefits in agricultural land prices. The resultant information is of crucial importance given the current change from price support to income support in agricultural policymaking. The results of the meta-analysis show that there is considerable variation due to the way in which income is taken into account, and the way in which expectations of future benefits are operationalized. There is also evidence that a change from a mixed price and income support scheme to a system of income support will result in substantially lower capitalization in land values.

description: Kerr-Schild solutions of the Einstein-Maxwell field equations, containing semi-infinite axial singular lines, are investigated. It is shown that axial singularities break up the black hole, forming holes in the horizon. As a result, a tube-like region appears which allows matter to escape from the interior without crossing the horizon. It is argued that axial singularities of this kind, leading to very narrow beams, can be created in black holes by external electromagnetic or gravitational excitations and may be at the origin of astrophysically observable effects such as jet formation.

description: The seasonal irrigation water demand under uncertainty, which lies at the core of this paper, is still very roughly known. We know, however, that irrigated agriculture accounts for a large proportion of water use, especially in many water-scarce areas. In this paper, we estimate the irrigation water demand, for various climatic conditions characterizing the distribution of the necessarily stochastic, demand functions under uncertainty. We use a dynamic programming model to represent the farmer's decision program under uncertainty. A crop-growth simulation model (EPIC-PHASE), provides the response function to the decisions taken and climatic events and is linked to a CRRA utility function representing the farmer's objective function. This model is used to generate the data allowing the estimation of irrigation water demand by a nonparametric procedure. An application to irrigation water demand is proposed in the South-West of France. We show that the estimated demand functions present four main areas: For very small quantities, where the farmer considers water as an essential input to crop growth, the demand is inelastic. The second area corresponds to mean quantities where the plant has reached a satisfactory level of growth; water is no more an essential input and is not yet a risk reducing input. The farmer is more responsive to change in water price. But, we find a third, non-intuitive, area for larger quantities where the water is a risk reducing input and the demand becomes inelastic again. The last area is classic, the water demand is obviously elastic for important total water quantities. This result is of great importance to analyze a regulation policy.

description: This study revealed the optimal conditions for the Ultrasonic-Assisted Enzymatic Extraction (UAEE) of silymarin, and include: the concentration of ethanol, 50 %; enzyme concentration, 30 U/mg; liquid-solid ratio, 6:1; an extraction time of 120 min; and the ultrasonic power at 180 W. The extraction rate was 7.86 %, which is higher, by 74.67 %, than that of the silymarin extract from the Silybum marianum meal prepared by a distinct approach. SEM micrographs of the inner and outer surfaces of the Silybum marianum shell obtained by variant extractions demonstrated that the extraction of silymarin required the destruction of cell walls. The results suggest that UAEE is a promising alternative for the extraction of silymarin. The antioxidant activities of the silymarin were evaluated in vitro by its capabilities to scavenger the DPPH, hydroxyl and superoxide free radicals, as well as by its tyrosinase inhibitory activity. The results showed that silymarin has significant antioxidant activity, thus it can be used as a functional food material against oxidative stress. We believe that the knowledge gained from this study should contribute to the further development and application of this resource.

description: We give the defining structure of two-parameter quantum group of type G_2 defined over a field {\Bbb Q}(r,s) (with r\ne s), and prove the Drinfel'd double structure as its upper and lower triangular parts, extending an earlier result of [BW1] in type A and a recent result of [BGH1] in types B, C, D. We further discuss the Lusztig's Q-isomorphisms from U_{r,s}(G_2) to its associated object U_{s^{-1},r^{-1}}(G_2), which give rise to the usual Lusztig's symmetries defined not only on U_q(G_2) but also on the centralized quantum group U_q^c(G_2) only when r=s^{-1}=q. (This also reflects the distinguishing difference between our newly defined two-parameter object and the standard Drinfel'd-Jimbo quantum groups). Some interesting (r,s)-identities holding in U_{r,s}(G_2) are derived from this discussion.

description: The purpose of the present study was to investigate whether the markers of oxidative stress could be altered in workers exposed to asbestos. A comparative cross-sectional research was conducted in a group of 50 subjects exposed to asbestos and another group of 50 with the same age and sex unexposed to asbestos. Malondialdehyde (MDA), total thiol molecule (TTM), total antioxidant capacity (TAC), and DNA damage, were measured in the blood samples of workers and controls. Compared to the control group, the workers showed higher blood levels of DNA damage (P=0.0001) and MDA (P=0.0001). The workers showed lower TTM (P=0.02) as compared with the control group. There was no considerable difference on the level of TAC (P=0.1) between the groups. The workers indicated clinical symptoms such as breathlessness, phlegm, coughing and wheezing. There was a positive correlation between levels of 8-OHdG and MDA of asbestos workers and the smoking status suggesting the negative role of smoking.

description: Currently licensed typhoid vaccines are based on Vi capsular polysaccharides. Recent molecular reports from typhoid endemic countries state that Salmonella enterica serovar Typhi (S. Typhi) Vi negative strains occur naturally and cause typhoid fever which is indistinguishable from disease caused by Vi positive strains. Vaccine based on Vi polysaccharide may not protect patients if the invading S. Typhi are negative for Vi. The lipopolysaccharide (LPS) is an essential component of S. Typhi outer membrane in which O-specific polysaccharide (OSP) is a protective antigen and universal candidate for vaccine development. In this study, S. Typhi Vi negative isolates were discriminated from Vi positive isolates through a duplex PCR using primers of fliC-d (599bp) and tviA (495bp) genes. The LPS of S. Typhi Vi negative isolates was extracted by hot phenol method and OSP was purified by core hydrolysis. The yield of extracted LPS was 91 mg/L and that of purified OSP was 49.14 mg/L of culture broth. LPS showed ladder like appearance by zinc imidazole staining following SDSPAGE. Whole cell challenged mice sera were used for in vitro antigenicity evaluation of the purified LPS and OSP. The antigenicity was found adequate by immunodiffusion assay. To our knowledge, this is the first report of purification and antigenic evaluation of LPS of a Vi negative S. Typhi isolate. The purified OSP from S. Typhi Vi negative isolate may be coupled with a carrier protein to produce universal low cost conjugate vaccine candidates for use in typhoid endemic regions.

description: We analyze bipartite matrices and linear maps between matrix algebras, which are respectively, invariant and covariant, under the diagonal unitary and orthogonal groups' actions. By presenting an expansive list of examples from the literature, which includes notable entries like the Diagonal Symmetric states and the Choi-type maps, we show that this class of matrices (and maps) encompasses a wide variety of scenarios, thereby unifying their study. We examine their linear algebraic structure and investigate different notions of positivity through their convex conic manifestations. In particular, we generalize the well-known cone of completely positive matrices to that of triplewise completely positive matrices and connect it to the separability of the relevant invariant states (or the entanglement breaking property of the corresponding quantum channels). For linear maps, we provide explicit characterizations of the stated covariance in terms of their Kraus, Stinespring, and Choi representations, and systematically analyze the usual properties of positivity, decomposability, complete positivity, and the like. We also describe the invariant subspaces of these maps and use their structure to provide necessary and sufficient conditions for separability of the associated invariant bipartite states.

description: Increasing trend of antibiotic resistance and expression of Extended Spectrum Beta Lactamases (ESBLs) are serious threats for public health as they render the treatment ineffective. Present study was designed to elucidate the antibiotic-susceptibility patterns of ESBL and non-ESBL producing E. coli and K. pneumoniae causing urinary tract infections so that the ineffective antibiotics could be removed from the line of treatment. The bacterial isolates obtained from the urine of patients visiting a tertiary health care facility were cultured for strain identification using API20E. Antimicrobial susceptibility and ESBL detection were done by Kirby-bauer diffusion technique. Almost 53.4 % isolates of E. coli and 24.5 % isolates of K. pneumoniae were found to be ESBL producers. The ESBL producing bacteria were found to be more resistant towards various antibiotics. The most effective drugs against E. coli ESBL isolates were imipenem (99.54 %), ampicillin-sulbactam (97.48 %), piperacillin-tazobactam (96.86 %), fosfomycin (94.51 %), amikacin (92.26 %) and nitrofurantoin (90.68 %). The most effective drugs against K. pneumoniae ESBL isolates were imipenem (97.62 %), piperacillin-tazobactam (95.35 %), ampicillin-sulbactam (90.48 %) and amikacin (88.37 %). The antibiotics having the highest resistance, particularly by the ESBL producers were amoxicillin clavulanic acid, sulphamethoxalzole/ trimethoprim, cefuroxime, cefpirome, ceftriaxone and ciprofloxacin. Most of the isolates showed multi drug resistance (MDR). High frequency of ESBL producing E. coli and K. pneumoniae were observed as compared to previous data. Penicillins, cephalosporins and some representatives of fluoroquinolones were least effective against the common UTIs and are recommended to be removed from the line of treatment.

description: Diffusive transport properties of a quantum Brownian particle moving in a tilted spatially periodic potential and strongly interacting with a thermostat are explored. Apart from the average stationary velocity, we foremost investigate the diffusive behavior by evaluating the effective diffusion coefficient together with the corresponding Peclet number. Corrections due to quantum effects, such as quantum tunneling and quantum fluctuations, are shown to substantially enhance the effectiveness of diffusive transport if only the thermostat temperature resides within an appropriate interval of intermediate values.

Neutrinoless double beta decay in dual-phase xenon time projection chambers: lux, lz and prospects for g3
Creators: name: Taylor, Robert
Publisher: name: Imperial College London
Year: 2020

description: The groundbreaking observation of neutrino oscillations indicates that the elusive neutrino is massive, providing tantalising evidence for physics beyond the standard model. However, given that neutrinos cannot obtain mass through the same mechanism as the charged leptons, unsolved problems still remain. Neutrinoless double beta decay (0νββ) is a hypothetical process that, if discovered, may shine light on the origins of neutrino mass. It would also confirm that Majorana fermions exist in nature, and that the neutrino is its own anti-particle, demonstrating that lepton number is not conserved through a fundamental symmetry of the universe. In this thesis, the capability of past, present and future dual-phase xenon time projection chambers to search for 136Xe 0νββ is demonstrated. A search for this process is performed in a short 19 kg·yr exposure of the LUX experiment, with the goal of illustrating the reconstruction of O(MeV) events in such detectors, and demonstrating the techniques required for future experiments. Next, the sensitivity of the LUX-ZEPLIN (LZ) experiment to the 0νββ half-life T1/2 is studied, revealing that after 1,000 days of exposure, LZ can exclude T1/2 < 1.06 × 1026 yr at 90% CL. A similar sensitivity projection is also performed for a hypothetical, large scale future detector that utilises O(100 tonnes) of xenon. It is shown that at this scale it is possible to exclude T1/2 < 1.0 × 1028 yr, and probe almost the entire inverted neutrino mass hierarchy at 90% CL. Finally, a machine learning method for fast simulation of the detector response using a generative adversarial network is studied. It is demonstrated that this technique can accurately generate the digitised photomultiplier signals resulting from interactions in a dual-phase detector. This technique may provide a computationally inexpensive method for fast simulation in future detectors.

description: The increasing demand and hampered use of primary human hepatocytes for research purposes have urged scientists to search for alternative cell sources, such as immortalized hepatic cell lines. The aim of this study was to develop a human hepatic cell line using the combined overexpression of TERT and the cell cycle regulators cyclin D1 and mutant isoform CDK4R24C. Following transduction of adult human primary hepatocytes with the selected immortalization genes, cell growth was triggered and a cell line was established. When cultured under appropriate conditions, the cell line expressed several hepatocytic markers and liver-enriched transcription factors at the transcriptional and/or translational level, secreted liver-specific proteins and showed glycogen deposition. These results suggest that the immortalization strategy applied to primary human hepatocytes could generate a novel hepatic cell line that seems to retain some key hepatic characteristics.

description: We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface Berry curvature scaling as $1/k^2$, where $k$ is the distance to a hot-line in the surface Brillouin zone that connects the projection of Weyl nodes with opposite chirality but which is distinct from the Fermi arc itself. Such surface Berry curvature appears whenever the bulk Weyl dispersion has a velocity tilt toward the surface of interest. This divergence is reflected in a variety of Berry curvature mediated effects that are readily accessible experimentally, and in particular leads to a surface Berry curvature dipole that grows linearly with the thickness of a slab of a Weyl semimetal material in the limit of long lifetime of surface states. This implies the emergence of a gigantic contribution to the non-linear Hall effect in such devices.

description: Η σύγχρονη εποχή χαρακτηρίζεται από μεγάλη αβεβαιότητα και συνεχείς αλλαγές. Οι επιχειρήσεις που καταφέρνουν να προσαρμόζονται σε αυτές τις αλλαγές έχουν μέλλον και θα καταφέρουν να διατηρήσουν το μερίδιο τους στην αγορά. Οι υπόλοιπες απλά θα εξαφανιστούν. Άλλο ένα γεγονός στις μέρες μας είναι η συνεχής αλλαγή και εξέλιξη της τεχνολογίας. Και σε αυτό τον τομέα υπάρχουν πολλές επιχειρήσεις που δυσκολεύονται να ακολουθήσουν αυτές τις εξελίξεις. Η αγορά σήμερα έχει γίνει παγκόσμια και ενιαία και δεν περιορίζεται στα όρια μιας χώρας. Επομένως οι μεταβολές και οι εξελίξεις επηρεάζουν όλες τις οικονομίες. Είναι φανερό ότι και η βιομηχανία της μόδας είναι μια παγκόσμια αγορά και επομένως οι τάσεις και οι προτιμήσεις των καταναλωτών ξεκινούν από ένα σημείο του πλανήτη και ταχύτατα εξαπλώνονται σε κάθε γωνία του. Η εξέλιξη της τεχνολογίας οδήγησε και στην ανάπτυξη των Logistics τα οποία με την σειρά τους βοήθησαν τις επιχειρήσεις να εξελιχθούν και να διατηρούν το ανταγωνιστικό πλεονέκτημα έναντι των αντιπάλων τους. Η παραδοσιακή βιομηχανία της μόδας με τους χαμηλούς χρόνους απόκρισης τείνει να εξαλειφθεί και την θέση της παίρνει η γρήγορη μόδα με την ταχεία απόκριση και την βελτίωση της εξυπηρέτησης του πελάτη. Άρα καταλαβαίνουμε ότι η αλυσίδα εφοδιασμού κάθε επιχείρησης είναι ζωτικής σημασίας και ενεργεί ώστε να μειωθούν οι χρόνοι απόκρισης και γενικότερα να μειωθεί ο χρόνος που χρειάζεται ένα προϊόν για να φτάσει από το στάδιο παραγωγής στον τελικό καταναλωτή. Σε αυτή την εργασία θα αναφερθούμε στις έννοιες των Logistics και της εφοδιαστικής αλυσίδας αλλά και στις διαφορές αυτών. Θα αναλύσουμε πως λειτουργεί η εφοδιαστική αλυσίδα της μόδας και τι προβλήματα παρουσιάζει. Τέλος θα γίνει μια έρευνα για την εταιρεία Zara και θα παρουσιαστούν οι ενέργειες και οι πρωτοποριακές κινήσεις της που την βοήθησαν να εξελιχθεί και να εξαλείψει τα προβλήματα που παρουσιάζουν οι άλλες επιχειρήσεις στον κλάδο.

description: We provide some considerations on the excitation of black hole quasinormal modes (QNMs) in different physical scenarios. Considering a simple model in which a stream of particles accretes onto a black hole, we show that resonant QNM excitation by hyperaccretion requires a significant amount of fine-tuning, and is quite unlikely to occur in nature. Then we summarize and discuss present estimates of black hole QNM excitation from gravitational collapse, distorted black holes and head-on black hole collisions. We emphasize the areas that, in our opinion, are in urgent need of further investigation from the point of view of gravitational wave source modeling.

description: Light-sheet fluorescence microscopy (LSFM) enables real-time whole-brain functional imaging in zebrafish larvae. Conventional one photon LSFM can however induce undesirable visual stimulation due to the use of visible excitation light. The use of two-photon (2P) excitation, employing near-infrared invisible light, provides unbiased investigation of neuronal circuit dynamics. However, due to the low efficiency of the 2P absorption process, the imaging speed of this technique is typically limited by the signal-to-noise-ratio. Here, we describe a 2P LSFM setup designed for non-invasive imaging that enables quintuplicating state-of-the-art volumetric acquisition rate of the larval zebrafish brain (5 Hz) while keeping low the laser intensity on the specimen. We applied our system to the study of pharmacologically-induced acute seizures, characterizing the spatial-temporal dynamics of pathological activity and describing for the first time the appearance of caudo-rostral ictal waves (CRIWs).

description: It has been proposed that gravothermal collapse due to dark matter self-interactions (i.e. self-interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (MW) satellites' central dynamical masses. We investigate the process behind this hypothesis using an $N$-body simulation of a MW-analogue halo with velocity dependent self-interacting dark matter (vdSIDM) in which the low velocity self-scattering cross-section, $σ_{T}/m_{x}$, reaches 100 cm$^{2}$g$^{-1}$; we dub this model the vd100 model. We compare the results of this simulation to simulations of the same halo that employ different dark models, including cold dark matter (CDM) and other, less extreme SIDM models. The masses of the vd100 haloes are very similar to their CDM counterparts, but the values of their maximum circular velocities, $V_{max}$, are significantly higher. We determine that these high $V_{max}$ subhaloes were objects in the mass range [$5\times10^{6}$, $1\times10^{8}$] $M_\odot$ at $z=1$ that undergo gravothermal core collapse. These collapsed haloes have density profiles that are described by single power laws down to the resolution limit of the simulation, and the inner slope of this density profile is approximately $-3$. Resolving the ever decreasing collapsed region is challenging, and tailored simulations will be required to model the runaway instability accurately at scales $<1$ kpc.

description: We investigate the large-scale statistics of a passive scalar transported by a turbulent velocity field. At scales larger than the characteristic lengthscale of scalar injection, yet smaller than the correlation length of the velocity, the advected field displays persistent long-range correlations due to the underlying turbulent velocity. These induce significant deviations from equilibrium statistics for high-order scalar correlations, despite the absence of scalar flux.
