description: A model for photoassociation of ultracold atoms and molecules is presented and applied to the case of 39K and 23Na39K bosonic particles. The model relies on the assumption that photoassociation is dominated by long-range atom-molecule interactions well outside the chemical bond region. The frequency of the photoassociation laser is chosen close to a bound-bound rovibronic transition from the X1Σ+ ground state toward the metastable b3Π lowest excited state of 23Na39K, allowing us to neglect any other excitation, which could hinder the photoassociation detection. The energy level structure of the long-range 39K···23Na39K excited super-dimer is computed in the space-fixed frame by solving coupled-channel equations, involving the coupling between the 23Na39K internal rotation and the mechanical rotation of the super-dimer complex. A quite rich structure is obtained, and the corresponding photoassociation rates are presented. Other possible photoassociation transitions are discussed in the context of the proposed model.

description: This paper studies the connection between the relativistic number density of galaxies down the past light cone in a Friedmann-Lemaitre-Robertson-Walker spacetime with non-vanishing cosmological constant and the galaxy luminosity function (LF) data. It extends the redshift range of previous results presented in Albani et al. (2007:astro-ph/0611032) where the galaxy distribution was studied out to z=1. Observational inhomogeneities were detected at this range. This research also searches for LF evolution in the context of the framework advanced by Ribeiro and Stoeger (2003:astro-ph/0304094), further developing the theory linking relativistic cosmology theory and LF data. Selection functions are obtained using the Schechter parameters and redshift parametrization of the galaxy luminosity functions obtained from an I-band selected dataset of the FORS Deep Field galaxy survey in the redshift range 0.5

On the Sources of the Inflationary Bias

description: Why do dynamic inconsistencies in monetary policy exist? In this paper we present a traditional model with output inefficiencies, but we allow for monetary policy to be influenced by the various constituencies in the economy, that pressure the Congress to in turn pressure the central bank to adopt a particular policy stance. We show that in this economy an inflationary-bias arises due to the lobbying pressure of outsiders. Furthermore, we show that if lobbying pressures are high enough, an inflationary-bias cannot be avoided for any finite level of central bank independence. We also show that introducing the realistic feature of lobbying pressures has an impact on the stabilization properties of monetary policy. When a supply shock occurs, the shock is totally absorbed by a forward-looking trade-union which has no costs of lobbying, independently of any finite degree of conservativeness and independence of the central banker, who has to accept an extreme increase in price instability. We show that monetary policy delegation is therefore sub-optimal in achieving price-stability compared to labor-market reforms meant to remove monopolistic elements. However, the same structural policies will induce greater output instability by strengthening the power of conservative central bankers.
Surface Approximation May Be Easier Than Surface Integration

Subjects: Computer science

description: The approximation and integration problems consist of finding an approximation to a function f or its integral over some fixed domain 6. For the classical version of these problems, we have partial information about the functions f and complete information about the domain 6; for example, 6 might be a cube or ball in R d . When this holds, it is generally the case that integration is not harder than approximation; moreover, integration can be much easier than approximation. What happens if we have partial information about 6? This paper studies the surface approximation and surface integration problems, in which 6 = 6g for functions g. More specifically, the functions f are r times continuously differentiable scalar functions of l variables, and the functions g are s times continuously differentiable injective functions of d variables with l components. The class of surfaces considered is generated as images of cubes or balls, or as oriented cellulated regions. Error for the surface approximation problem is measured in the Lq - sense. These problems are well-defined, provided that d ≤ l, r ≥ 0, and s ≥ 1. Information consists of function evaluations of f and g. We show that the ε-complexity of surface approximation is proportional to (1/ε) 1/µ with µ = min{r,s}/d. We also show that if s ≥ 2, then the ε-complexity of surface integration is proportional to (1/ε) 1/ν with ν = min r d , s − δs,1(1 − δd,l) min{d, l − 1}. (This bound holds as well for several subcases of s = 1; we conjecture that it holds for all r ≥ 0, s ≥ 1, and d ≤ l.) Using these results, we determine when surface approximation is easier than, as easy as, or harder than, surface integration; all three possibilities can occur. In particular, we find that if r = s = 1 and d < l, then µ = 1/d and ν = 0, so that surface integration is unsolvable and surface approximation is solvable; this is an extreme case for which surface approximation is easier than surface integration.

description: We numerically obtain a class of soliton solutions for Einstein gravity in $(n+1)$ dimensions coupled to massive abelian gauge fields and with a negative cosmological constant with Lifshitz asymptotic behaviour. We find that for all $n\geq3$, a discrete set of magic values for the charge density at the origin (guaranteeing an asymptotically Lifshitz geometry) exists when the critical exponent associated with the Lifshitz scaling is $z=2$; moreover, in all cases, a single magic value is obtained for essentially every $12$ sufficiently.

description: Relying on data for a panel of 90 economies over 1970-2015 and System-GMM estimates, we extend the standard Kuznets-curve empirical framework to investigate how financial development, globalisation and technology affect income inequality. Our findings reveal the presence of significant nonlinearities, consistent with either U-shaped or inverted U-shaped relationships. As such, depending on whether a certain threshold value is achieved, the same determinants of income distribution can exert opposite effects in different countries. Globalisation is associated to increasing inequality in most advanced economies, but to falling disparities for the large majority of emerging economies. Further, while the effects for advanced economies are mixed, technology and financial development lead to increasing inequality for most emerging economies. Hence, particularly in countries in earlier stages of development, policymakers aiming at fostering growth via technological progress or financial development should also consider the nature of the trade-offs with inequality and how policy can improve them.

description: While web communications are increasingly protected by transport layer cryptographic operations (SSL/TLS), there are many situations where even the communications infrastructure provider cannot be trusted. The end-to-end (E2E) encryption of data becomes increasingly important in these trust models to protect the confidentiality and integrity of the data against snooping and modification by the communications provider. We introduce W3Bcrypt, an extension to the Mozilla Firefox web platform that enables application-level cryptographic protection for web content. In effect, we view cryptographic operations as a type of style to be applied to web content along with layout and coloring operations. Among the main benefits of using encryption as a stylesheet are (a) reduced workload on a web server, (b) targeted content publication, and (c) greatly increased privacy. This paper discusses our implementation for Firefox, but the core ideas are applicable to most current browsers.

description: The self-consistent random phase approximation (RPA), based on the framework of relativistic energy density functionals, is employed in the study of isovector and isoscalar dipole response in $^{68}$Ni, $^{132}$Sn, and $^{208}$Pb. The evolution of pygmy dipole states (PDS) in the region of low excitation energies is analyzed as a function of the density-dependence of the symmetry energy for a set of relativistic effective interactions. The occurrence of PDS is predicted in the response to both the isovector and isoscalar dipole operators, and its strength is enhanced with the increase of the symmetry energy at saturation and the slope of the symmetry energy. In both channels the PDS exhausts a relatively small fraction of the energy-weighted sum rule but a much larger percentage of the inverse energy-weighted sum rule. For the isovector dipole operator the reduced transition probability $B(E1)$ of the PDS is generally small because of pronounced cancellation of neutron and proton partial contributions. The isoscalar reduced transition amplitude is predominantly determined by neutron particle-hole configurations, most of which add coherently, and this results in a collective response of the PDS to the isoscalar dipole operator.

description: Devices made of few molecules constitute the miniaturization limit that both inorganic and organic-based electronics aspire to reach. However, integration of millions of molecular junctions with less than 100 molecules each has been a long technological challenge requiring well controlled nanometric electrodes. Here we report molecular junctions fabricated on a large array of sub-10 nm single crystal Au nanodots electrodes, a new approach that allows us to measure the conductance of up to a million of junctions in a single conducting Atomic Force Microscope (C-AFM) image. We observe two peaks of conductance for alkylthiol molecules. Tunneling decay constant (beta) for alkanethiols, is in the same range as previous studies. Energy position of molecular orbitals, obtained by transient voltage spectroscopy, varies from peak to peak, in correlation with conductance values.

Tax cuts, employment and asset prices: A real intertemporal model

description: We determine the effects of a delayed or immediate tax cut with or without a "sunset" feature in a real customer-market, non-Ricardian economy. Our model incorporates both the supply-sider channel as well as the Feldstein-Rubin-Summers channel. We show that a tax cut may depress both the real asset price and employment. The presence of the paradoxical result of employment contraction does not work through nor imply an immediate increase of the long real interest rate, contrary to financial commentators. A similar analysis applies to the huge pension problem burdening several continental European economies so part of their high unemployment of late may be ascribed to their looming pension outlays.

description: The $B^0_{s,d} \to J/ψη^{(\prime)}$ decays provide new terrain for exploring CP violation. After briefly discussing $η$-$η'$ mixing, we analyse the effective lifetimes and CP-violating observables of the $B_s$ channels, which allow us to probe New-Physics effects in $B^0_s$-$\bar B^0_s$ mixing. We have a critical look at these observables and show how hadronic corrections can be controlled by means of the $B_d$ decays. Using measurements of the $B^0_{s,d}\to J/ψη^{(\prime)}$ branching ratios by the Belle collaboration, we discuss tests of the $SU(3)_F$ flavour symmetry of strong interactions, obtain the first constraints on the hadronic parameters entering the $B^0_{s,d} \to J/ψη$ system, and predict the $B^0_d\to J/ψη'$ branching ratio at the $5\times10^{-6}$ level. Furthermore, we present strategies for the determination of the $η$-$η'$ mixing parameters from the $B^0_{s,d} \to J/ψη^{(\prime)}$ observables. We also observe that the $B^0_{s,d} \to J/ψη$ and $B^0_{s,d} \to J/ψη'$ decays are - from a formal point of view - analogous to the quark-antiquark and tetraquark descriptions of the $f_0(980)$ in the $B^0_{s,d} \to J/ψf_0(980)$ channels, respectively.

description: The recent influx of Chinese newcomers to major Canadian metropolitan regions has brought about an evolution of ethnic business enclaves. With increasing concentrations of business immigrants in suburban neighbourhoods, Asian theme malls have created a new form of commercial activity and became a prevalent retail phenomenon. Through literature review, a set of distinct operational, structural, and spatial features are identified to characterize the ethnocultural element of Asian theme malls. Using these features as the analytical framework, this Master's Degree Project aims to explore the planning implication and development pattern of Asian theme malls through a case study in Calgary and a precedent study in Markham of Metropolitan Toronto. The findings suggest that a number of issues associated with the distinct characteristics of Asian theme malls have emerged in both regions, although at a smaller magnitude and a more recent occurrence in Calgary. Since Markham and other municipalities around the Metropolitan Toronto can be considered as more experienced in planning for ethnocultural diversity, this study focuses on their current planning practice and development strategy that have emerged in response to the changing trend of Asian theme malls. Through a combination of social programs and technical regulations, the planning authority of Metropolitan Toronto considers the ethnocultural aspect of the developments and serves as an exemplary practice for the City of Calgary.

Was there a Riverside miracle? An hierarchical framework for evaluating programs with grouped data

Publisher: name: Columbia University
Year: 2002

description: This paper uses data from the Greater Avenues for Independence (GAIN) demonstration to discuss the evaluation of programs that are implemented at multiple sites. Two frequently used methods are pooling the data or using fixed effects (an extreme version of which estimates separate models for each site). The former approach, however, ignores site effects. Though the latter incorporates site effects, it lacks a framework for predicting the impact of subsequent implementations of the program (e.g., will a new implementation resemble Riverside or Alameda?). I present an hierarchical model that lies between these two extremes. For the GAIN data, I demonstrate that the model captures much of the site-to-site variation of treatment effects, but has less uncertainty than a model which estimates treatment effects separately for each site. I also show that uncertainty in predicting site effects is important: when the predictive uncertainty is ignored, the treatment impact for the Riverside sites is significant, but when we consider predictive uncertainty, the impact for the Riverside sites is insignificant. Finally, I demonstrate that the model is able to extrapolate site effects with reasonable accuracy, when the site for which the prediction is being made does not differ substantially from the sites already observed. For example, the San Diego treatment effects could have been predicted based on observable site characteristics, but the Riverside effects are consistently underestimated.

description: Achilles tendinopathy is an overuse injury affecting jumping athletes, associated with the accumulation of microdamage due to repetitive tendon strain. Surface and footwear modifications may influence tendon strain magnitude. The purpose of this thesis was to examine the influence of surface and footwear modifications on Achilles tendon strain during vertical countermovement jump landings and to quantify the relationship between tendon strain and accelerometer measures. The parameters were quantified for three shoes (Boost™, 55C, and 70C) and three surfaces (ACS, BC3, and MVP) using motion capture, accelerometry, and dynamometry-ultrasound measures. Surface and footwear influenced Achilles tendon strain; strain was lower in the Boost™ shoe and MVP surface conditions. Differences in strain could be due to stiffness or other material properties of the shoes and surfaces. Only weak correlations were found between tendon strain and accelerometer measures, suggesting that data obtained from accelerometers may not reflect internal loading.
Curve forecasting by functional autoregression

Subjects: Economics

description: Data in which each observation is a curve occur in many applied problems. This paper explores prediction in time series in which the data is generated by a curve-valued autoregression process. It develops a novel technique, the predictive factor decomposition, for estimation of the autoregression operator, which is designed to be better suited for prediction purposes than the principal components method. The technique is based on finding a reduced rank approximation to the autoregression operator that minimizes the norm of the expected prediction error. Implementing this idea, we relate the operator approximation problem to an eigenvalue problem for an operator pencil that is formed by the cross-covariance and covariance operators of the autoregressive process. We develop an estimation method based on regularization of the empirical counterpart of this eigenvalue problem, and prove that with a certain choice of parameters, the method consistently estimates the predictive factors. In addition, we show that forecasts based on the estimated predictive factors converge in probability to the optimal forecasts. The new method is illustrated by an analysis of the dynamics of the term structure of Eurodollar futures rates. We restrict the sample to the period of normal growth and find that in this subsample the predictive factor technique not only outperforms the principal components method but also performs on par with the best available prediction methods.

description: We propose a measure of holographic information based on a causal wedge construction. The motivation behind this comes from an attempt to understand how boundary field theories can holographically reconstruct spacetime. We argue that given the knowledge of the reduced density matrix in a spatial region of the boundary, one should be able to reconstruct at least the corresponding bulk causal wedge. In attempt to quantify the `amount of information' contained in a given spatial region in field theory, we consider a particular bulk surface (specifically a co-dimension two surface in the bulk spacetime which is an extremal surface on the boundary of the bulk causal wedge), and propose that the area of this surface, measured in Planck units, naturally quantifies the information content. We therefore call this area the causal holographic information. We also contrast our ideas with earlier studies of holographic entanglement entropy. In particular, we establish that the causal holographic information, whilst not being a von Neumann entropy, curiously enough agrees with the entanglement entropy in all cases where one has a microscopic understanding of entanglement entropy.

description: Background: Many patients with cardiovascular disease also show a high comorbidity of mental disorders, especially such as anxiety and depression. This is, in turn, associated with a decrease in the quality of life. Psychocardiological treatment options are currently limited. Hence, there is a need for novel and accessible psychological help. Recently, we demonstrated that a brief face-to-face metacognitive therapy (MCT) based intervention is promising in treating anxiety and depression. Here, we aim to translate the face-to-face approach into digital application and explore the feasibility of this approach. Methods: We translated a validated brief psychocardiological intervention into a novel non-blended web app. The data of 18 patients suffering from various cardiac conditions but without diagnosed mental illness were analyzed after using the web app over a two-week period in a feasibility trial. The aim was whether a non-blended web app based MCT approach is feasible in the group of cardiovascular patients with cardiovascular disease. Results: Overall, patients were able to use the web app and rated it as satisfactory and beneficial. In addition, there was first indication that using the app improved the cardiac patients’ subjectively perceived health and reduced their anxiety. Therefore, the approach seems feasible for a future randomized controlled trial. Conclusion: Applying a metacognitive-based brief intervention via a non-blended web app seems to show good acceptance and feasibility in a small target group of patients with CVD. Future studies should further develop, improve and validate digital psychotherapy approaches, especially in patient groups with a lack of access to standard psychotherapeutic care.

description: Age-related macular degeneration (AMD) is a genetically complex disorder of the photoreceptor-RPE-Bruch's membrane-choriocapillaris complex. Family and twin studies have shown that the susceptibility for this disease is genetically influenced. The heritability has been estimated to be up to 71%. Linkage and association studies have identified several chromosomal regions that are likely to contain susceptibility loci with strongest evidence found on chromosome 1q31 and 10q26. Variants in the complement factor H (CFH) gene have been shown by several independent studies to be associated with an increased risk for AMD in Caucasian populations. These findings imply that the innate immune system may play a significant role in AMD pathogenesis. The LOC387715/HTRA1 locus within 10q26 has been identified as a second major locus contributing to AMD pathogenesis. The two late forms of AMD, choroidal neovascularization and geographic atrophy, have not been found to be different in risk allele distribution. Variants within CFH and LOC387715/HTRA1 may contribute to the increased risk of late AMD largely through their impact on precursors, such as drusen and/or other RPE/Bruch's membrane changes. Considering variants at CFH, LOC387715/HTRA1 and complement component 2-complement factor B (C2-FB), high-risk homozygotes at all three loci may have a 250-fold increased risk compared to baseline. However, the identification of genetic factors has not resulted in therapeutic strategies to modify the disease so far and additional genetic and environmental factors are yet to be discovered in order to influence the onset and the progression of AMD.

description: The effect of total factor productivity (TFP) on exports particularly interests policy-makers and economists, but empirical evidence is ambiguous. This paper uses the 6-wave panel data in 2010-2015 to investigate the impact of TFP on export transitions at the firm level. We distinguish different types of export transitions, namely start, stop, continuity, fluctuation, and striving, and different phases of export transition. The Generalised Method of Moments (GMM) estimation is applied to control for endogeneity and unobserved time-invariant specific components. The results reveal that (i) the effect of productivity on export (the self-selection hypothesis) is heterogeneous, depending on specific sectors and types and phases of export transitions; (ii) productivity growth does not necessarily result in positive effects on and lead to participation in types and phases of export transitions. Our results also reveal strong evidence of favourable sunk cost in long-run export striving in nearly all sectors, and unlike previous studies, empirical results show a negative effect of sunk cost in some manufacturing sectors. Policy-makers should create dynamic comparative advantages and favourable environments for new exporters, focus the relevant policies on productivity stimulus, and strengthen the likelihood of survival for the domestic firms in the competitive global markets.
Chiral Separations Using a Modified Water Stationary Phase in Supercritical fluid Chromatography

Year: 2018

description: A novel means of achieving chiral separations in supercritical fluid chromatography (SFC) using a water stationary phase is presented. By adding various chiral selectors to the phase, different chiral analytes can be readily separated using neat CO2 as a mobile phase. For example, by adding β-cyclodextrin, it is found that certain flavanone enantiomers can be separated, while using the antibiotic vancomycin as a selector provides separation of some chiral phenoxypropionic acids. Other additives such as sodium chloride and triethylamine are also explored and found to enhance certain separations when also present in the water phase. While column pressure has a moderate impact on chiral analyte retention and separation in this SFC method, column temperature has a comparatively larger influence. In particular, relatively cooler temperatures below about 5 °C are found to markedly increase resolution and selectivity. For instance, notably large resolution of 4.7 is achieved for a phenoxypropionic acid pair at 0 °C and 150 atm CO2. Since the method does not require modifier to elute such polar species, it is also readily compatible with FID detection and does not generate organic waste. Therefore, results indicate that this approach could be a potentially simple and flexible means of achieving chiral separations in SFC.

description: In early innovation phases, the monetary evaluation of process innovations is a challenge for companies due to a lack of data. However, an innovation evaluation is essential in an early innovation phase to ensure that process innovations deliver economic value added (EVA) in early innovation phases and to channel technology transfer expenditures in a goal-oriented manner. This paper presents an approach for a semi-quantitative procedure for the monetary evaluation of process innovations in the early innovation phase focusing on manufacturing and material costs. Exemplarily, the approach is applied to process innovations of the Collaborative Research Center 1368 on oxygen-free production. In order to ensure the net present value orientation within the innovation evaluation, the procedure developed is based on a driver tree of the EVA. To link value drivers of the EVA and innovation-driven factors influencing EVA, the EVA driver tree is further systematized with a focus on manufacturing and material costs using a literature-based impact model. Based on the last level of the impact model, a guideline for a semi-structured expert interview is developed. Using this interview guideline, data is collected in the form of innovation-driven influencing factors, which represent the input for the final monetary innovation evaluation. An adapted weighted scoring model is used to draw a semi-quantitative conclusion regarding the EVA achieved by the process innovation. The practical application of the approach developed to process innovations in oxygen-free production has shown that, in the context of three process innovations under consideration, their implementation with the aim of achieving an EVA through reduced manufacturing and material costs at the current innovation status is not effective. However, based on the impact model developed, corresponding levers can be identified to positively influence the EVA and thus also the industrialization of the process innovation. Finally, further necessary steps are identified to evolve the presented approach into a complete method for monetary innovation evaluation in early innovation phases.
The Design of High-Throughput Asynchronous Pipelines
Creators: name: Singh, Montek
Publisher: name: Columbia University
Year: 2001
Subjects: Computer science

description: Clocked or synchronous design has traditionally been used for nearly all digital systems. However, it is now facing significant challenges as clock rates reach several GigaHertz, chip sizes increase, and the demand for low power and modular design become paramount. An alternative paradigm is clockless or asynchronous design, which has several potential advantages towards meeting these challenges. This thesis focuses on the design of very high-speed asynchronous systems. A more specific focus of this thesis is on high-throughput asynchronous pipelines, since pipelining is at the heart of most high-performance systems. This thesis contributes four new asynchronous pipeline styles: 'lookahead,' 'high-capacity,' 'MOUSETRAP' and 'dynamic GasP' pipelines. The styles differ from each other in many aspects, such as protocols, storage capacity, implementation style, and timing assumptions. The new styles are capable of multi-GigaHertz throughputs in today's silicon technology (e.g., 0.13-0.18 micron), yet each style has a simple implementation. High throughputs are obtained through efficient pipelining of systems at a fine granularity, though the pipeline styles are also useful for coarser-grain applications. The basic pipeline styles are extended to address several issues that arise in practice while designing real-world systems. In particular, the styles are generalized to handle a greater variety of architectures (e.g., datapaths with forks and joins), and to robustly interface with arbitrary-speed environments. Finally, the approaches of this thesis are validated by designing and fabricating real VLSI subsystems, including: simple FIFO's, pipelined adders, and an experimental digital FIR filter chip. All chips were tested to be fully functional; throughputs of over 2.4 GHz for the FIFO's, and up to 1.3 GHz for the FIR filter, were obtained in an IBM 0.18 micron technology.

description:  3. Two novelties allied to B. velutina (sect. Barleria) – Barleria obtecta is very closely allied to B. velutina, and pertains to the same section, Barleria. The same holds for B. sceptrum­katanganum, allied to B. velutina by its hairiness and the shape of calyces and leaves; it differs by its strongly erect stem which is broader than in B. velutina, by its leafy spike, the leafy bracts hiding the calyx lobes which are not visible unlike in B. velutina, by the constant presence of the upper lobes of corolla, which are much larger than those of B. velutina when present in the latter, and by its considerably larger leaves.

description: The tree of heaven (Ailanthus altissima) is a widespread invasive plant. It secretes specialized metabolites, so called quassinoids, into the soil to inhibit competing plants. Quassinoids therefore bear biotechnological potential for plant protection as well as medicinal applications. Here, I describe how reconstitution of biochemical pathways in the model plant Nicotiana benthamiana enables the discovery of genes for quassinoid biosynthesis as a prerequisite for biotechnological applications.

description: We explore the dark matter interpretation of the anomalies claimed by the DAMA and CoGeNT experiments, in conjunction with the various null direct-detection experiments. An independent analysis of the CoGeNT data is employed and several experimental and astrophysical uncertainties are considered. Various phenomenological models are studied, including isospin violating interactions, momentum-dependent form factors, velocity-dependent form factors, inelastic scatterings (endothermic and exothermic) and channeling. We find that the severe tension between the anomalies and the null results can be ameliorated but not eliminated, unless extreme assumptions are made.

description: In this report for Deliverable 4.4 of E-CAM, nine software modules in meso– and multi–scale modelling are presented. Four of the modules have been implemented in DL_MESO_DPD:

• Ewald method for the GPU version of DL_MESO_DPD

• Smooth Particle Mesh Ewald (SPME) method for the GPU version of DL_MESO_DPD

• Analysis of local tetrahedral ordering for DL_MESO_DPD

• Consistency check of input files in DL_MESO_DPD

Five of the modules concern the Grand Canonical Adaptive Resolution Scheme (GC-AdResS) and have been developed, implemented and tested in/with GROMACS 5.1.0 and GROMACS 5.1.5. The patches provided are for GROMACS 5.1.5. The modules provide a recipe to simplify the implementation and to allow to look into a microcanonical (i.e., NVE-like) environment. They are based on the same principles as the Abrupt AdResS modules reported in a previous deliverable D4.3[1].

Furthermore, we provide all the tools necessary to run and check the AdResS simulations. The modules are:

• Local Thermostat Abrupt AdResS

• Thermodynamic Force Calculator for Abrupt AdResS

• Energy (AT)/Energy(interface) ratio: Necessary condition for AdResS simulations

• Velocity-Velocity autocorrelation function for AdResS

• AdResS-Radial Distribution Function (RDF).

A short description is written for each module, followed by a link to the respective Merge-Request on the GitLab service of E-CAM. These merge requests contain detailed information about the code development, testing and documentation of the modules.
