description: We investigate the effect of isotope substitution on the electronic spectral functions within a model where the charge carriers are coupled to bosonic charge-order (CO) fluctuations centered around some mean frequency ω_0 and with enhanced scattering at wave-vector q_c. It is shown that a mass dependence of ω_0 is not sufficient in order to account, especially at high energies, for the dispersion shifts experimentally observed in an optimally doped superconducting cuprate. We argue that isotope substitution induces a change of the spatial CO correlations which gives good account of the experimental data.

description: Minor merger of galaxies are common during the evolutionary phase of galaxies. Here, we investigate the dynamical impact of a minor merger (mass ratio 1:10) event on the final fate of a stellar bar in the merger remnant. To achieve that, we choose a set of minor merger models from the publicly available GalMer library of galaxy merger simulations. The models differ in terms of their orbital energy, orientation of the orbital spin vector, and morphology of the satellite galaxy (discy/spheroidal). We demonstrate that the central stellar bar, initially present in the host galaxy, undergoes a transient bar amplification phase after each pericentre passage of the satellite; in concordance with past studies of bar excitation due to tidal encounter. However, once the merger happens, the central stellar bar weakens substantially in the post-merger remnants. The accumulation of satellite's stars in the central region of merger remnant plays a key role in the bar weakening process; causing a net increase in the central mass concentration as well as in the specific angular momentum content. We find that the efficiency of mass accumulation from the satellite in the central parts of merger remnants depends on the orbital parameters as well as on the satellite's morphology. Consequently, different minor merger models display different degrees of bar weakening event. This demonstrates that minor merger of galaxies is a plausible avenue for bar weakening in disc galaxies.

description: The response of thyme (Thymus vulgaris L.) lo sources of nitrogen (N) fertilizer application was studied in field experiments conducted in 1992 and 1993. Thyme plants were grown in plots consisting of 3 rows 2.1 m long with 40 cm between rows. In 1992, thyme plants were fertilized with N at a rate of 115 kg. ha4 using N-source treatments of ammonium nitrate (35% N), ammonium sulfate (21% N), and urea (45% N). One treatment was applied with cow manure (2% N) at a rate of 230 kg N. ha '. A control plot (no N) was included as a treatment. In 1993, the same N fertilizer sources were used but N was applied at a rate of 100 kg. ha"' for inorganic fertilizers and 200 kg. ha"' for organic (cow manure) fertilizer. In both experiments phosphorus (P) and potassium (K) were applied at a rate similar to the P and K content of cow manure equivalent to 50 and 190 kg. ha in 1992 and 44 and 166 kg.ha"' in 1993, respectively. In 1992, results indicated no significant differences in plant height, plant fresh yield and total dry matter yield among nitrogen fertilizer sources and the control. Results obtained in 1993 showed that urea and cow manure were superior to ammonium nilrate and the control in terms of total plant fresh yield. Plants fertilized with urea and cow manure produced total fresh yields of 7.5 and 7.2 t. ha ', respectively. Lowest plant fresh yield of 5.1 t ha ' was obtained from plots applied with ammonium nitrate. No significant differences in plant height were observed between treatments. It appears that urea and cow manure are the best sources of N fertilizer for thyme production in the Virgin Islands.

description: A series of studies were conducted to evaluate the effects of varying rates of nitrogen fertilizer and applied irrigation, on yam production. Yam was grown in field trials with nitrogen applied at rates of 0, 100, 200 and 300 kg/ha. The application of nitrogen did not affect the production of yam tubers from either of two cultivars ('Binugas' and 'Gunung'). Yields were similar for both cultivars at all nitrogen levels. The results of another study showed that nitrogen applied to 'Gunung' at rates of 0, 50, 100 and 150 kg/ha significantly affected yield and dry matter production. Yam production decreased linearly as nitrogen rates increased. Two trials were conducted to evaluate the effect of varying irrigation rates (rain-fed and soil moisture maintained at 20,40 and 60 kPa) on the production of 'Binugas' yams. The application of irrigation quadratically decreased the dry matter content of the yam tubers, in both trials.

description: The value of Jamaican yellow yam (Dioscorea cayenensis) exported in 1992 was US$9.9m. These yams are produced in a traditional system where all yams are staked and planted on individual mounds. The traditional sy stem of production contributes to soil erosion on the hillsides where most of the crop is grown. Based on the importance of the crop, the minisett system of production was introduced to improve the system of production. Four on-farm trials were conducted to determine the effects of sett type, sett sizes, staking and mulch on tuber yield from yellow yam minisetts. It was found that sett size and type did not affect total tuber yield. A quantitative assessment of the number and weight of marketable tubers produced in defined weight categories showed that tuber size was influenced by staking and mulching. Experimental yields from 17.7 t/ ha to30.9t/ha were higher than national average yield of 12t/ha.Agronomic implications were discussed.

description: We consider the correlation between the binding energies of the triton and the alpha-particle which is empirically observed in calculations employing different phenomenological nucleon-nucleon interactions. Using an effective quantum mechanics approach for short-range interactions with large scattering length |a| >> l, where l is the natural low-energy length scale, we construct the effective interaction potential at leading order in l/|a|. In order to renormalize the four-nucleon system, it is sufficient to include a SU(4)-symmetric one-parameter three-nucleon interaction in addition to the S-wave nucleon-nucleon interactions. The absence of a four-nucleon force at this order explains the empirically observed correlation between the binding energies of the triton and the alpha-particle. We calculate this correlation and obtain a prediction for the alpha-particle binding energy. Corrections to our results are suppressed by l/|a|.

description: The availability of official time series of Italian underground employment and VAT tax evasion for the period 1980-2004 allow us to investigate empirical1y the long- and short-run characteristics of two components of the Italian Non Observed Economy (NOE). The analysis focuses on a time span during which major labour market and fiscal reforms occurred in Italy, with an evident impact on long-run dynamics of both underground employment and tax evasion. Our investigation pointed out several interesting short-run regularities. The cyclical behaviour of the non-regular labour input indicates that the resources allocated to the underground economy are mostly motivated by flexibility requirements. Moreover, the dynamic adjustments of employment between the regular and underground market, are inextricably tied one to each other over the cycle, highlighting a reallocation mechanism among labour inputs or a labour drag effect. As to the size of the VAT evasion, its short term dynamic suggests a strategic behaviour by taxpayers, aiming to smooth tax liabilities expressed as a share of revenues.

description: We observe a strong dependence of the exciton spin relaxation in CdTe quantum dots on the average dot size and the depth of the confining potential. For the excitons confined to the as-grown CdTe quantum dots we find the spin relaxation time to be 4.8 ns. After rapid thermal annealing, which increases the average dot size and leads to weaker confinement, we measure the spin relaxation tine to be 1.5 ns, resulting in smaller values of the absolute polarization of the quantum dot emission. This dramatic enhancement of the spin scattering efficiency upon annealing is attributed to increased mixing between different spin states in larger CdTe quantum dots.

description: Die Lehre algorithmischen Denkens, einer der grundlegenden Fähigkeiten der Informatik, ist eine herausfordernde Aufgabe. Das Propädeutikum für angehende Studierende der Informatik an der Technischen Universität Wien nutzt dazu ein Computerprogramm namens Theseus das die Ausführung von Algorithmen zur Lösung von Labyrinthen darstellt um so die Diskussion von Algorithmen greifbarer zu machen. Theseus beschreibt die ausgeführten Algorithmen allerdings nicht explizit, sodass die Studenten nicht einsehen können was "in" diesen passiert während am Bildschirm die Suche nach dem Zielpunkt eines Labyrinths veranschaulicht wird. Diese Diplomarbeit untersucht wie eine interaktive Lernumgebung nicht nur die Ausführung sondern auch die Formulierung von Algorithmen ermöglichen kann um so die Lehre algorithmischen Denkens zu unterstützen und den Lerneffekt für Studierende zu erhöhen. Nach Analyse des didaktischen Handlungsspielraums und der Auswahl eines geeigneten, an der konstruktionistischen Lerntheorie ausgerichteten Vorgehens beschreibt diese Arbeit die konkrete Implementierung einer neuen, online verfügbaren Lernumgebung namens Ariadne welche eine visuelle Programmiersprache zur Beschreibung von Algorithmen integriert. Studenten und Lehrer können damit die von Ariadne vordefinierten Algorithmen zur Lösungssuche in Labyrinthen verstehen, sie verändern und sogar völlig neue Algorithmen entwerfen.
description: Teaching algorithmic thinking, which is one of the fundamental skills in computer science, is a challenging task. Preparatory courses for budding students of computer science at the Vienna University of Technology use a computer program called Theseus to visualise the execution of maze solving algorithms, thus making the discussion of algorithms more tangible. However, Theseus does not explicitly describe the executed algorithms and students are left to wonder what is happening "inside" them while the search for a maze's finish is visualised on screen. This thesis investigates how an interactive learning environment can not only execute but also formulate maze algorithms in order to support the teaching of algorithmic thinking and increase the learning effect for students. After performing an analysis of various didactic options and selecting a suitable approach that is aligned with the constructionist learning theory, the actual implementation of a new online learning environment called Ariadne is described, which integrates a visual programming language for describing algorithms. This allows students and teachers to understand Ariadne's pre-defined maze solving algorithms, to modify them and to even create new algorithms from scratch.

description: Three cassava cultivars, Serralles, Sta. Catarina, and Zenon, were field evaluated at nine and 12 months after planting for root tuber yield and hydrocyanic acid potential (HCN-p) on an Oxisol at the ARS Farm, Isabela, Puerto Rico, during 1993-94. Significant differences were found in root tuber yield and HCN-p among cvs. and also in replication x cv. and HCN-p for replications and harvest dates. Sta. Catarina cv. averaged the highest root tuber yield with 31.9 tons/ha, while the Zenon cv. had the lowest HCN-p, 39.1 ppm. Across cvs., there was no significant difference between the two harvest dates in terms of root tuber yield; however, the root tuber HCN-p was significantly lower at the nine-month harvest (45.6 ppm). According to the findings of a taste-testing panel, the root tubers of all three cvs. at the two harv est dates had good culinary quality. However, at nine months, root tubers of the Zenon cv. were considered superior to the other two cvs.; while, at 12 months, those of the Sta. Catarina cv. were slightly preferred by the panel.

description: The drying behavior of the dashecn leaf under natural convection conditions at temperatures ranging from 40-70<>C was studied in an attempt to develop a dehydrated product from this popular vegetable often used in soups and commonly called - 'callaioo.' The effects of various pretreatments on the drying behavioral of the vegetable at 60°C were also studied, viz. steam blanching (96°C for 6 min ), water blanching (near boiling for 10s) and blanching in 0.06% magnesium carbonate at near boiling for 10 s prior to immersion in a mixed chemical bath consisting mainly of 20% sucrose, for 4 h at 21°C. Two falling rate periods of drying were observed for dashecn leaves dried at 40-70°C. However, a single falling rate period of drying was found for the water and magnesium carbonate blanched-infused vegetable at 60°C. Although drying rates markedly increased with increasing drying temperature, drying at high temperatures particularly at 60°C and 70°C resulted in a deleterious color change from green, typical of the fresh vegetable, to an unattractive olive-brown or brown discoloration. Steam blanching appeared to have no significant effect on the drying rate of the dasheen leaf compared to fresh leaves while for the water blanched vegetable, the drying rate was reduced by 50%. Compared to water blanching, alkali blanching was found to have no significant effect on the drying rate of the dasheen leaf. Blanching in water or alkali resulted in a superior dehydrated product which, unlike the steam blanched vegetable, showed minimal loss of green color.
Weak response of nuclei

description: We discuss some differences and similarities between electron and neutrino scattering off atomic nuclei. We find that, in the giant resonance region, the two processes excite different nuclear modes, therefore the weak and the electromagnetic nuclear responses are rather different. In any case, the scattering of electrons and photons is the best guide we have to test the validity of our nuclear models and their prediction power. The experience in describing electromagnetic excitations of the nucleus, suggests that, when the nucleus is excited in the continuum, the re-interaction between the emitted nucleon and the remaining nucleus should not be neglected. A simple model taking into account this final state interaction is proposed, and applied to the neutrino scattering off 16O nucleus.

description: James Boswell has generally been regarded as a key figure in the evolution of the biography via his work on Samuel Johnson. Ranging over his public, published writing, his private-public unpublished journal writing (read by his friend John Johnston), and his private-private unpublished writing (his personal journals) this thesis sets out to address how he should also be seen as a travelogue writer of note. The most important contention is that the rise of Boswell as a travel writer is key to understanding his prowess as an auto/biographical writer – with the topography of the man-monument central. The principal aim is to stress that he was ‘Corsica Boswell’ long before he was ‘Johnson Boswell’.
title: Potential Microbial Processes In An Ancient Martian Environment, An Investigation Into Bio-Signature Production And Community Ecology

Publisher: name: The Open University
Year: 2017

description: This work investigated whether the River Dee estuary can be considered as an martian environmental analogue and examined the whether an understanding of microbial processes could inform future life detection missions on Mars. The subsurface environment of the River Dee estuary, UK, and its microbial community, was characterised and compared to the palaeolake at Gale Crater, Mars. Similarities were identified in pH, temperature and Total Organic Carbon measurements, as well as potential bioessential element availability (based on comparative mineralogy of the two sites). The microbial community at the River Dee site was also characterised, indicating that a diverse bacterial community thrived there, alongside a single dominant archaeal group. This provided key insight into potential microbial communities on Mars, and associated processes that may inform future Mars research. Since the diversity and attributes of microorganisms is directly linked to their environment, the microbial community of the River Dee estuary was used to investigate potential martian geomicrobiological processes and community dynamics within a simulated martian experimental environment. Concentrations of the bioessential elements Fe, Mg and K were seen to increase in the biological experiments when compared with abiotic controls, leading to, for example, a 143 μmol L-1 difference in the concentration of Fe during the stationary phase. One bacterial group, the Acidobacteria Gp9, dominated the microbial community for 400 hr during the stationary phase, accounting for ~58 % of the microbial community at its peak. For a subsequent experiment, five bacterial species were isolated from the simulated martian environment, and characterised in order to demonstrate their growth optima and tolerance to relevant environmental extremes. Clostridium amygdalinum was found to be a model organism for survival within environments like the palaeolake at Gale Crater, and is proposed as a useful biological analogue for future investigations of the potential of life in such environments on Mars.
An evaluation of two existing methods for analyzing longitudinal respiratory symptom data
Creators: name: Arrandale, Victoria Helen
Publisher: name: University of British Columbia
Year: 2011

description: Due to the complexities of analyzing repeated binary outcomes, changes in respiratory symptoms over time are rarely studied. In fact, most respiratory epidemiology studies to date have not taken full advantage of longitudinal symptom data. This thesis evaluated discrete mixture models (SAS® Proc Traj) and generalized linear mixed models (SAS® Proc Glimmix) with respect for their applicability to six basic respiratory symptom research questions. These methods are both capable of handling repeated binary outcome data and permit inclusion of time varying covariates. These two techniques were then applied in a case study. Results from the evaluation of the methods indicated that Proc Glimmix can model the predictors of respiratory symptoms as well as population trends in symptom reporting over time. But Proc Glimmix is not suitable for modeling pattern or shape of change over time. In contrast, Proc Traj models patterns of change over time, and identifies multiple subgroups within the population. Proc Traj is not capable of modeling overall population trends. Both methods have statistical limitations that researchers need to understand; to help with this a simple guide describing both techniques was compiled. The case study utilized longitudinal data from a population of marine workers and focused on the outcome breathlessness, or dyspnea. Results from both Proc Traj and Proc Glimmix models indicated that the probability of reporting dyspnea changed over time in this population. Proc Traj models identified two distinct patterns of change in the population (one increasing over time, one steady over time). Proc Glimmix models identified several factors that were associated with dyspnea reporting; older age, childhood asthma, smoking and being female were associated with more dyspnea, whereas better lung function and current exposure to respiratory irritants were associated with less dyspnea. The overall conclusion was that both Proc Traj and Proc Glimmix models are suitable for analyzing repeated binary respiratory symptom data and researchers are encouraged to consider their use. Proc Glimmix is best for modeling the predictors of reporting a symptom at the population level, while Proc Traj is suited for modeling multiple subgroups in the population and their patterns of change over time.

description: Nowadays, the agricultural data can be generated through various sources, such as: Internet of Thing (IoT), sensors, satellites, weather stations, robots, farm equipment, agricultural laboratories, farmers, government agencies and agribusinesses. The analysis of this big data enables farmers, companies and agronomists to extract high business and scientific knowledge, improving their operational processes and product quality. However, before analysing this data, different data sources need to be normalised, homogenised and integrated into a unified data representation. In this paper, we propose an agricultural data integration method using a constellation schema which is designed to be flexible enough to incorporate other datasets and big data models. We also apply some methods to extract knowledge with the view to improve crop yield; these include finding suitable quantities of soil properties, herbicides and insecticides for both increasing crop yield and protecting the environment.

description: The aim of this paper is to estimate the sensitivity of the natural rate of growth to the actual rate of growth for the Italian regions over the period 1980-2003. To do this, a panel approach based on the methodology proposed by Leon-Ledesma and Thirdwall has been proposed. The results support the idea that the natural rate of growth depends on the actual rate of growth: the rate of output growth necessary to keep the percentage level of unemployment constant rises in boom periods and falls in recessions. Moreover, the influence of aggregate demand on potential growth is different in the two main Italian macro areas (Centre-Northern and Southern Italy). In particular, given the lower participation of the labour force and higher reserves of labour in general, the sensitivity of the natural rate of growth to the actual rate of growth is higher in Southern Italy where, besides, the results suggest the presence of structural unemployment.

description: Drug discovery programmes for pain suffer from poor clinical translation, despite many drugs gaining in-vivo efficacy. Subsequently, patient populations are poorly served by existing, often ineffective, and sometimes harmful, analgesics. One way to address poor clinical translation and ameliorate clinical trial failure rates, is to use human genetic data to validate molecular targets in a translational context, whilst stratifying patient groups using genetic variants. Ion channels highly expressed along nociceptive pathways are rapidly emerging as important molecular components in the mechanisms of pain, of which the two-pore domain potassium (K2P) family are one group of unexploited therapeutic targets with good in-vitro/vivo pre-clinical validation and existing genetic linkage in small scale studies. To understand the role of K2Ps in pain within large scale populations, a functional genomic target validation approach was applied using genome-wide association study (GWAS) results. The association of >135,0000 K2P gene loci variants with pain subtypes was investigated in the UK and Finnish Biobanks, and in-silico characterisation undertaken to predict their epidemiological and molecular penetrance, in stratified populations. Select variants were characterised using patch clamp electrophysiology, thallium flux, RT-qPCR, and live-cell imaging to support cellular phenotype prediction in patients. Altogether, 18 variants were strongly associated with distinct pain subtypes within the gene-loci for KCNK18, KCNK5/16/17, KCNK13, KCNK10, KCNK7, KCNK3 and KCNK1, amongst many suggestive signals of weaker effect. These results benchmarked particularly well against, and in some cases surpassed the genetic association data of other reputed ion channel pain-associated gene targets (TRP and SCNA). An investigation into the pleiotropic effect of these K2P variants in patients with pain who also dose regularly with analgesic medications, identified even stronger links, suggesting complex trait genetics for these variants. Functional characterisation of select KCNK10 variants in translated and untranslated regions of the gene, demonstrated altered functional activity with the potential to modify pain-sensing thresholds in patients by affecting the regulation of the membrane potential in nociceptive neurones or by other mechanistic routes in alternative cell types. The validation of both molecular and clinical data from large patient groups, has shown that pain-association and susceptibility markers exist within select K2P gene loci, some of which cause alterations in ion channel activity, in-vitro. These data combined, suggest an important role for K2P ion channels in pain and represent promising novel analgesic targets that could ameliorate complex pain conditions.

description: Saving energy in general and heating energy in particular has always been in the focus of research and development. Progress of technology, the potential of modern electronics, and advances in the digital world have led to many new practical opportunities to reduce the heating demand of buildings. In this context, one field of research concentrates on state-of-the-art control strategies. Electronics and microprocessors have become very powerful and reasonably priced and applications as embedded control have taken an important role in our life. This technology has also entered the thermal control of buildings, homes and apartments. 'Smart' thermostats are a fast growing market and attract start-ups as well as big players in computer engineering. The applied technologies follow different paths to achieve energy savings. Use of advanced control systems is an important direction of research. And there, control algorithms using predictive control algorithms are one of these potential ways and are showing promising results. These prediction algorithms allow for optimized control strategies, taking into account a wide range of input parameters. The basis for the prediction and optimization process is a good knowledge about the systems characteristics, either by an empirically established set of system responses or by a mathematical model representing the thermal dynamics of the controlled zone. Both ways allow forecasting the thermal systems output as a reaction to an applied control input and to disturbance parameters. For a selected actual room, different predictive types of controllers and their respective energy saving potential is discussed. Switching thermostats with simple predictive methods as well as more complex model predictive control algorithm are compared. Also variations of sensor and input data configurations are compared in view of the achieved simulated energy savings.

description: Keratocystic odontogenic tumors (KCOTs) are locally invasive, rapidly proliferating cystic lesions of the jaw. The bone-invasive nature of these tumors has been previously associated with the expression of matrix metalloproteinases (MMPs), which degrade the extracellular matrix. The purpose of this study was to assess the expression and activity of MMPs in primary KCOT cells and tumor tissue. Methods: Four independently established KCOT primary cell populations were grown in Dulbecco’s modified Eagle medium supplemented with 10% FBS and antibiotics. Primary cells were analyzed by qRT-PCR and immunohistochemistry (IHC), and for secretion of active MMPs. Primary tumor sections were analyzed by IHC. Results: Of the 18 human MMPs examined, 9 were consistently expressed in primary KCOT cells. MMP-2 and MMP-14 were highly expressed in all KCOT populations, while MMP-1, 3, 11, 12, 16, 17, and 19 were moderately expressed. MMP-3, 11, 12, 16, 17 and 19 were shown to be expressed in KCOTs for the first time. No significant differences in MMPS profiles were found between syndromic (KCOT-3) and non-syndromic cell populations (KCOT-1/2/4). Protein expression of MMP-1, 11, 12, 14 and 16 was confirmed in each KCOT cell populations by IHC. KCOT-3 cells secreted active MMP-2 as determined by a gel zymography assay. Expression of MMP-1, 2, 3, 11, 12, 14, and 16 was confirmed in matching primary KCOT tumor sections representing syndromic and non-syndromic KCOTs. Conclusion: KCOT primary cell populations and tumors express a wide range of MMPs, which likely play a role in the bone-invasive nature of these tumors.

description: An analytic theory of species abundance patterns (SAPs) in biological networks is presented. The theory is based on multispecies replicator dynamics equivalent to the Lotka-Volterra equation, with diverse interspecies interactions. Various SAPs observed in nature are derived from a single parameter. The abundance distribution is formed like a widely observed left-skewed lognormal distribution. As the model has a general form, the result can be applied to similar patterns in other complex biological networks, e.g. gene expression.

title: Inadequacies of current liability regimes in the nuclear industry

description: Nuclear industry needs an effective and adequate liability regime. Significant attention has been given to develop an international nuclear liability regime in order to promote appropriate compensation for nuclear damage during the years. This was reflected in the various conventions, as followed: The Paris Convention on Third Party Liability, The Vienna Convention on Civil Liability for Nuclear Damage, The Brussels Supplementary Convention, The Protocol to Amend the Vienna Convention on Civil Liability for Nuclear Damage, The Protocol to Amend the Paris Convention on Nuclear Third Party Liability, The Protocol to Amend the Brussels Convention Supplementary to the Paris Convention and The Convention on Supplementary Compensation for Nuclear Damage. Despite the efforts, the attempt to improve the regime has not been completely successful. Current regimes have not been widely ratified and left many shortcomings, which include: the exclusive liability to the operator of the nuclear installation, the limitation of liability in quantum and limitation in time for making claims, the exclusive jurisdiction for claims to the installation states, a narrow definition of damage, lack of an adequate compensation fund and lack of members. The tragic events in Chernobyl, Three Mile Island or Fukushima have illustrated that accidents can happen and the consequences can be huge. With this in the mind the present work brings recommendations, for an improved and effective regime to govern the nuclear liability system: no limitation liability in quantum and duration, proportionality liability of the state, manufacturer and operator, access to neutral tribunal, a broad definition of damages, no statute of limitation, the establishment of an adequate compensation fund and increased membership. Many of these recommendations can be found in the national nuclear laws of different states. For harmonization the national law and practice with the international nuclear regime, it is important that both national and international system to converge. The ideas put forward might be controversial, however it could go a long way to improve the system.

description: Experimental results related to charged particle and $π^{0}$ suppression obtained at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven for Au-Au (Cu-Cu) collisions and at the Large Hadron Collider (LHC) at CERN for Pb-Pb (Xe-Xe) collisions are compiled in terms of the usual nuclear modification factors, $R_{AA} $ and $R_{CP}$, and of the newly introduced $R^{N}_{AA}$ and $R^{N}_{CP}$ as a function of $\langle N_{part} \rangle$ and $\langle dN_{ch}/dη\rangle$. The studies are focused on a $p_T$ range in the region of maximum suppression evidenced in the experiments. The core contribution to $R_{AA}$ is presented. Considerations on the missing suppression in high charged particle multiplicity events for pp collisions at 7 TeV are presented. The trends of $R_{CP}$ and $R^N_{CP}$ for charged particles and $R_{AA}^{π^0}$ and $(R_{AA}^N)^{π^0}$ as a function of $\sqrt{s_{NN}}$, measured at RHIC in Au-Au collisions and at LHC in Pb-Pb collisions, show a suppression that becomes larger from $\sqrt{s_{NN}}$ = 39 GeV up to $\sqrt{s_{NN}}$=200 GeV, followed by a saturation up to the highest energy of $\sqrt{s_{NN}}$ =5.02 TeV in Pb-Pb collisions. A clear change in the dependence of $(1-R_{AA}^{π^0})/\langle dN/dy \rangle$ for the most central collisions as a function of collision energy is evidenced in the region of $\sqrt{s_{NN}}$ =62.4 - 130 GeV.

description: Cloud cavitation causes nontrivial energy concentration and acoustic shielding in liquid, and its control is a long-standing challenge due to complex dynamics of bubble clouds. We present a new framework to study closed-loop control of cavitation through acoustic feedback. While previous approaches used empirical thresholding, we employ model-based state estimation of coherent bubble dynamics based on theory and high-performance computing. Using a pulsed ultrasound setup, we demonstrate set-point control of the pulse repetition frequency (PRF) to modulate acoustic cavitation near a solid target over $O(100)$ s. We identify a quasi-equilibrium correlation between PRF and the bubble dynamics, and an optimal PRF to minimize acoustic shielding of the target. This framework can be readily scaled up by enhanced acoustic sensing and computational power.

description: Analytical expressions for covariances of weak lensing statistics related to the aperture mass $\Map$ are derived for realistic survey geometries such as SNAP for a range of smoothing angles and redshift bins. We incorporate the contributions to the noise due to the intrinsic ellipticity distribution and the effects of finite size of the catalogue. Extending previous results to the most general case where the overlap of source populations is included in a complete analysis of error estimates, we study how various angular scales in various redshifts are correlated and how the estimation scatter changes with survey parameters. Dependence on cosmological parameters and source redshift distributions are studied in detail. Numerical simulations are used to test the validity of various ingredients to our calculations. Correlation coefficients are defined in a way that makes them practically independent of cosmology. They can provide important tools to cross-correlate one or more different surveys, as well as various redshift bins within the same survey or various angular scales from same or different surveys. Dependence of these coefficients on various models of underlying mass correlation hierarchy is also studied. Generalisations of these coefficients at the level of three-point statistics have the potential to probe the complete shape dependence of the underlying bi-spectrum of the matter distribution. A complete error analysis incorporating all sources of errors suggest encouraging results for studies using future space based weak lensing surveys such as SNAP.
