description: Lexical semantic resources, like WordNet, are often used in real applications of natural language document processing. For example, we integrated GermaNet in our document suite XDOC of processing of German forensic autopsy protocols. In addition to the hypernymy and synonymy relation, we want to adapt GermaNet's verb frames for our analysis. In this paper we outline an approach for the domain related enrichment of GermaNet verb frames by corpus based syntactic and co-occurred data analyses of real documents.

description: Systems modeling practice lacks security analysis tools that can interface with modeling languages to facilitate security by design. Security by design is a necessity in the age of safety critical cyber-physical systems, where security violations can cause hazards. Currently, the overlap between security and safety is narrow. But deploying cyber-physical systems means that today's adversaries can intentionally trigger accidents. By implementing security assessment tools for modeling languages we are better able to address threats earlier in the system's lifecycle and, therefore, assure their safe and secure behavior in their eventual deployment. We posit that cyber-physical systems security modeling is practiced insufficiently because it is still addressed similarly to information technology systems.
Application of Search-Based Software Testing in Stress-Testing of Deeply Embedded Components in Integrated Circuits

description: Modern Integrated Circuits (ICs) based system design have evolved over time to support the ever demanding complex use-cases. As more functionality is packed into these ICs, there are more deeply embedded components present in these ICs. The performance of these deeply embedded components are critical in ensuring the final system behaviour. By virtue of being deeply embedded they are intrinsically difficult to test - especially in system context. This thesis is focused on the task of `stress testing' an IC in its operational environment with the goal of identifying any circumstances under which the circuit might suffer from performance issues. It addresses how search-based algorithms provide an automated approach in testing these ICs. Here it establishes that with a suitable search-space representation search-based approaches can be applied in stress-testing of complex ICs. Here it outlines how a simple hill-climbing based search algorithm is successfully used to generate tests in an automated manner. It also studies the application of more advanced search-based algorithms like random-restart hill-climbing and simulated annealing in addressing this testing challenge. As system behaviour of complex ICs can be affected in multiple ways, this research investigates the application of multiobjective algorithms in this context. It shows that a multi-objective algorithm like Strength Pareto Evolutionary Algorithm 2 (SPEA2) is able to generate better stress tests, maximising multiple objectives. The empirical studies performed as part of this thesis are conducted on ArmR Cache Coherent Interconnect (CCI), which provides cache coherency and interconnect functionality on modern Arm based systems. It concludes that search-based software testing approaches are indeed suitable for addressing testability challenges posed by modern ICs especially at system level and provide ways to generate better stress tests.
A simple renormalization group approximation of the groundstate properties of interacting bosonic systems

description: We present a new, simple renormalization group method of investigating groundstate properties of interacting bosonic systems. Our method reduces the number of particles in a system, which makes numerical calculations possible for large systems. It is conceptually simple and easy to implement, and allows to investigate the properties unavailable through mean field approximations, such as one- and two-particle reduced density matrices of the groundstate. As an example, we model a weakly interacting 1D Bose gas in a harmonic trap. Compared to the mean-field Gross-Pitaevskii approximation, our method provides a more accurate description of the groundstate one-particle density matrix. We have also obtained the Hall-Post lower bounds for the groundstate energy of the gas. All results have been obtained by the straightforward numerical diagonalization of the Hamiltonian matrix.

description: A deformation parameter of a bihamiltonian structure of hydrodynamic type is shown to parameterize different extensions of the AKNS hierarchy to include negative flows. This construction establishes a purely algebraic link between, on the one hand, two realizations of the first negative flow of the AKNS model and, on the other, two-component generalizations of Camassa-Holm and Dym type equations. The two-component generalizations of Camassa-Holm and Dym type equations can be obtained from the negative order Hamiltonians constructed from the Lenard relations recursively applied on the Casimir of the first Poisson bracket of hydrodynamic type. The positive order Hamiltonians, which follow from Lenard scheme applied on the Casimir of the second Poisson bracket of hydrodynamic type, are shown to coincide with the Hamiltonians of the AKNS model. The AKNS Hamiltonians give rise to charges conserved with respect to equations of motion of two-component Camassa-Holm and two-component Dym type equations.

description: The article presents modeling of inflationary scenarios for the first time in the $f(R,T)$ theory of gravity. We assume the $f(R,T)$ functional from to be $R + ηT$, where $R$ denotes the Ricci scalar, $T$ the trace of the energy-momentum tensor and $η$ the model parameter (constant). We first investigated an inflationary scenario where the inflation is driven purely due to geometric effects outside of GR. We found the inflation observables to be independent of the number of e-foldings in this setup. The computed value of the spectral index is consistent with latest Planck 2018 dataset while the scalar to tensor ratio is a bit higher. We then proceeded to analyze the behavior of an inflation driven by $f(R,T)$ gravity coupled with a real scalar field. By taking the slow-roll approximation, we generated interesting scenarios where a Klein Gordon potential leads to observationally consistent inflation observables. Our results makes it clear-cut that in addition to the Ricci scalar and scalar fields, the trace of energy momentum tensor also play a major role in driving inflationary scenarios.

description: We consider the arrival time distribution defined through the quantum probability current for a Gaussian wave packet representing free particles in quantum mechanics in order to explore the issue of the classical limit of arrival time. We formulate the classical analogue of the arrival time distribution for an ensemble of free particles represented by a phase space distribution function evolving under the classical Liouville's equation. The classical probability current so constructed matches with the quantum probability current in the limit of minimum uncertainty. Further, it is possible to show in general that smooth transitions from the quantum mechanical probability current and the mean arrival time to their respective classical values are obtained in the limit of large mass of the particles.

description: We study TCP flows coexistence between Massive Multiplayer Online Role Playing Games (MMORPGs) and other TCP applications, by taking World of Warcraft (WoW) and a file transfer application based on File Transfer Protocol (FTP) as an example. Our focus is on the effects of the sender buffer size and FTP cross-traffic on the queuing delay experienced by the (MMORPG) game traffic. A network scenario corresponding to a real life situation in an ADSL access network has been simulated by using NS2. Three TCP variants, namely TCP SACK, TCP New Reno, and TCP Vegas, have been considered for cross-traffic. The results show that TCP Vegas is able to maintain a constant rate while competing with the game traffic, since it prevents packet loss and high queuing delays by not increasing the sender window size. TCP SACK and TCP New Reno, on the other hand, tend to continuously increase the sender window size, thus potentially allowing higher packet loss and causing undesired delays for the game traffic. In terms of buffer size, we have established that smaller buffers are better for MMORPG applications, while larger buffers contribute to a higher overall delay.

description: Composing and interacting with music through electronic devices mapped on the body has been a new aspect of music this last 50 years. Technologies have improved greatly, making the interaction with computers within the context of music very attractive.

Human communication and interaction has a lot to do with the body expression. Hands are one of the most expressive and active parts of the body. They are our tool to interact with the environment. However, most the electronic devices to create music are not intuitive and they require experience and learning. This project designs a glove controller, which allows to create a natural human way to interact and communicate in the context of music technology.

The work in this project aims to map and recognize the expression of the hands, and their movements and gestures to interact, create and perform music. This thesis covers the process of creating an interactive glove controller, its communications processes and the interpretation of the gestures of the hand movements.

description: In corporate and commercial environments, the deployment of a set of coordinated Wi-Fi APs is becoming a common solution to provide Internet coverage to moving users. In these scenarios, real-time services as online games can also be present. This paper presents a set of experiments developed in a test scenario where an end device moves between different APs while generating game traffic. A WLAN solution based on virtual APs is used, in order to make the handoffs transparent for Layer 3. The results show that it is possible to maintain an acceptable level of subjective quality during the handoff. At the same time, it is set clear that the fact of having a gamer in an AP could be taken into account by radio resource management algorithms, in order to provide a better quality.
Visual Community Organising: A Graphic Account of the Use of Visual Tools and Methods in Grassroots Organising

Year: 2020
Subjects: Uncategorized

description: This document is the written element of a practiced-based PhD. It contains descriptive and analytical aspects of research conducted with the use of visual methods. Those methods have been used to explore and visualize a specific form of grassroots or community based organizing. Organized by and for communities of struggle, this form of community organizing - that I refer to as ‘visual community organizing’ (VCO) relies on the collective use of visual tools, exercises and activities. The use of these tools is meant to facilitate the creation of a shared, common understanding of a problem faced by what I call a community of struggle. In order to approach, analyze and understand this form of community organizing, the research that I conducted draws on the concept of visuality as a guiding tool. This concept allowed me to produce an adequate response to work that is otherwise difficult to describe in words. This is why the PhD relies on a narrative visual structure and methodology to approximate the work of those collectives. The concept of visuality is understood in this research as a form and expression of the different ways in which hegemonic power manifests itself. The specific manifestations of hegemonic power addressed in this dissertation are based on the experiences of seven collectives. The visual and organizational work of those collectives is the basis for this study. Presenting their experiences in visual form, the research will show how these visual community organizers use graphic and visual methods with the objective to imagine, facilitate, build and promote different expressions of counter-hegemonic visuality.The PhD is divided in two elements: a visual narrative in the form of a comic, and the written element that you are reading now. This document, the written element of the PhD, will narrate context and the methodology applied to approximate the work of VCOs. The visual element of this work on the other hand will show that each collectives’ expression of counter-hegemonic visuality as well as their organizing modality is adjusted around the specific situations in which they facilitate their work. To present these, the dissertation is structured methodologically in a way that draws together the processes that underpin the visual production of each collective. In order to do this, its focus is on a visual narrative that describes an account of histories that empower groups and build solidarities.
Phase transitions in one dimension: are they all driven by domain walls?

description: Two known distinct examples of one-dimensional systems which are known to exhibit a phase transition are critically examined: (A) a lattice model with harmonic nearest-neighbor elastic interactions and an on-site Morse potential, and (B) the ferromagnetic, spin 1/2 Ising model with long-range pair interactions varying as the inverse square of the distance between pairs. In both cases it can be shown that the domain wall configurations become entropically stable at, or very near, the critical temperature. This might provide a "positive" criterion for the occurrence of a phase transition in one-dimensional systems.

description: We discuss the possibility of a Lifshitz regime, where the dispersion relation for Goldstone bosons and related fields has a minimum at nonzero momenta. Studies with the Functional Renormalization Group suggest that this occurs over a wide region in the plane of temperature and baryon chemical potential. Conversely, the FRG finds that the region in which fluctuations from a critical endpoint are significant is rather small. We suggest that this is due generically to the narrowness of the tricritical region in the chiral limit. Even if particles are produced in thermal equilibrium, a dispersion relation which is non-monotonic in momenta produces what appears to be non-thermal behavior.

description: Scalar Gauss-Bonnet gravity is the only theory with quadratic curvature corrections to general relativity whose field equations are of second differential order. This theory allows for nonperturbative dynamical corrections and is therefore one of the most compelling case studies for beyond-general relativity effects in the strong-curvature regime. However, having second-order field equations is not a guarantee for a healthy time evolution in generic configurations. As a first step towards evolving black-hole binaries in this theory, we here derive the 3+1 decomposition of the field equations for any (not necessarily small) coupling constant and we discuss potential challenges of its implementation.

Cultures of Learning in Indonesia: enacting the HE language curriculum

Subjects: Uncategorized

description: Learners have different preferences and approaches when it comes to language learning. It is believed that these views have cultural origins. This study aims to identify these origins by determining the students’ ‘cultures of learning’ (Cortazzi and Jin, 1996). Although several studies have been carried out on Chinese students’ cultures of learning, this study focuses on Indonesian students’ cultures of learning and their teachers’ perceptions of their cultures of learning and investigates the effect on students’ agency and teachers’ development of methods of language teaching. This study sets out to answer the following research questions: (1) What are students’ cultures of learning? (2) What are teachers’ perceptions of students’ cultures of learning? (3) How do cultures of learning affect students’ learning practices? and (4) How do teachers’ perceptions of students’ cultures of learning affect the enactment of the curriculum? The study used a qualitative method to capture the voices of participants, students and teachers involved in English foreign language classes at five Indonesian universities. To create trustworthy outcomes for the study, a triangulation of methods was employed for the collection of the data, including likert scale questionnaires involving 127 students, 26 unstructured classroom observations (1hr-3hr), and 21 teachers’ and 30 students’ semi-structured interviews (approximately 20-40min). The main findings of this study are presented in four parts. The first part discusses how students’ approaches to learning are shaped by an educational-transmitted culture. The second part shows what beliefs teachers have about students’ cultures of learning. Teachers’ role in affiliating with the students in the classroom influenced their choices of features that influenced their practices, and how they involved students in the decision-making process. Part three of the findings outlines students' preferred cultures of learning. It was found that they mostly prefer to be ‘followers’, although they showed general attitudes towards certain teaching and learning methods in the classroom where a range of different approaches to learning were found likely to be more or less effective. Part four discusses teachers' current practices where there is room for students to be involved; however, the teachers may not understand that they can use students’ characters and wants; they are currently not aware that this is a part of students’ cultures of learning. What emerges from this current study is the importance of TESOL professionals recognising the importance of involving students’ voices from their cultures of learning when planning and delivering their courses and lessons.

description: We introduce a method to relate a possible truncation of the star cluster mass function at the high mass end to the shape of the cluster luminosity function (LF). We compare the observed LFs of five galaxies containing young star clusters with synthetic cluster population models with varying initial conditions. The LF of the SMC, the LMC and NGC 5236 are characterized by a power-law behavior NdL~L^-a dL, with a mean exponent of = 2.0 +/- 0.2. This can be explained by a cluster population formed with a constant cluster formation rate, in which the maximum cluster mass per logarithmic age bin is determined by the size-of-sample effect and therefore increases with log(age/yr). The LFs of NGC 6946 and M51 are better described by a double power-law distribution or a Schechter function. When a cluster population has a mass function that is truncated below the limit given by the size-of-sample effect, the total LF shows a bend at the magnitude of the maximum mass, with the age of the oldest cluster in the population, typically a few Gyr due to disruption. For NGC 6946 and M51 this implies a maximum mass of M_max = 5*10^5 M_sun. Faint-ward of the bend the LF has the same slope as the underlying initial cluster mass function and bright-ward of the bend it is steeper. This behavior can be well explained by our population model. We compare our results with the only other galaxy for which a bend in the LF has been observed, the ``Antennae'' galaxies (NGC 4038/4039). There the bend occurs brighter than in NGC 6946 and M51, corresponding to a maximum cluster mass of M_max = 2*10^6 M_sun (abridged).

description: For an isotropic and homogeneous nonlinear left-handed materials, for which the effective medium approximation is valid, Maxwell's equations for electric and magnetic fields lead naturally, within the slowly varying envelope approximation, to a system of coupled nonlinear Schroedinger equations. This system is equivalent to the well-known Manakov model that under certain conditions, is completely integrable and admits bright and dark soliton solutions. It is demonstrated that left- and right-handed (normal) nonlinear mediums may have compound bright and dark soliton solutions, respectively. These results are also supported by numerical calculations.

description: The development of a Modulation System Simulator is described. The Modulation System Simulator is used to investigate the performance, in the presence of noise, of various analog and digital modulation systems. The methods of modulation studied using this simulator are amplitude modulation, frequency modulation, pulse amplitude modulation, pulse code modulation, amplitude shift keying modulation, and frequency shift keying modulation. For each of these modulation systems a mathematical model is devised and then analyzed to predict the performance of each modulation system in the presence of noise. The results of this theoretical analysis are then compared with the experimental results obtained using the Modulation System Simulator and any differences between the two are accounted for.

description: Raman and IR spectroscopic measurements were carried out in formamide (FA) solutions containing variable SnCl4 contents. Pyramidal FA molecules play a major role in these media and are characterised by new bands at 1746, 1190 and 796 cm−1, which may be used as makers. The electrostatic potential (φ) of the coordinated ion shows good relationship with the arising of these bands, which are only seen in the spectra as the cation presents φ ≥ 3.9 × 1020 J C−1. Pyramidalisation of FA is due to the presence of a quaternary N in the [Sn(FA)2Cl2]2+ complex, which is formed along with [SnCl6]2-. The major Sn(IV)-based complexes are structurally similar to those commonly identified in aqueous medium.

description: Arrays of identical limit-cycle oscillators have been used to model a wide variety of pattern-forming systems, such as neural networks, convecting fluids, laser arrays, and coupled biochemical oscillators. These systems are known to exhibit rich collective behavior, from synchrony and traveling waves to spatiotemporal chaos and incoherence. Recently, Kuramoto and his colleagues reported a strange new mode of organization--here called the chimera state--in which coherence and incoherence exist side by side in the same system of oscillators. Such states have never been seen in systems with either local or global coupling; they are apparently peculiar to the intermediate case of nonlocal coupling. Here we give an exact solution for the chimera state, for a one-dimensional ring of phase oscillators coupled nonlocally by a cosine kernel. The analysis reveals that the chimera is born in a continuous bifurcation from a spatially modulated drift state, and dies in a saddle-node collision with an unstable version of itself.

description: Iron-based catalysts can be used as de-NOx catalysts due to their good adsorption performance to gas molecules. However, the adsorption behaviours of NH3, NO, and O2 molecules on ferrous oxide surface are unclear. In this paper, the adsorption properties of NH3, NO, and O2 molecules over FeO (100) surface and oxygen-defected FeO (100) surface were studied by a density functional theory calculation. The Fe-top of the FeO (100) surface is the most active site. NH3 and NO can be adsorbed on the Fe-top sites by N terminal. The adsorption of O2 on the Hollow site of the FeO (100) surface has a larger adsorption energy. When oxygen-defected presents on the FeO (100) surface, the adsorption performances of NH3 and NO on the Fe-top sites are slightly decreased. NO and O2 can be adsorbed on the O-defected site, in which the adsorption energy of O2 is larger. For the adsorption of double molecules, O2 + NH3 or O2 + NO adsorbed on the FeO (100) surface have synergistic effects, respectively, which enhance the adsorption performance. Moreover, the co-adsorption behaviours of O2 + NH3 and O2 + NO on the O-defected FeO (100) surface also occur.
Structural elements associated with the provision of phamaceutical care in community phamacy practice in Canada

description: The concept of pharmaceutical care is a philosophy of practice and has been presented to be an effective process for monitoring drug therapy to meet the needs of patients and the health care system. A number of pharmaceutical care models and practice guidelines have been proposed, developed and implemented in community pharmacy settings. As the pharmacy profession becomes more patient-focused using pharmaceutical care standards, it is important that pharmacists be able to assess the quality of that care and recognize the barriers that impede the provision of that care. Farris and Kirking maintain that Donabedian's structure-processoutcome paradigm can be applied to pharmaceutical care as a framework of quality assessment. Structure represents a necessary measure of quality and its assessment is crucial when structure can be associated with process and/or outcomes. This current study addresses the structure and process components of pharmaceutical care and reviews the structural elements that support the provision of pharmaceutical care in community pharmacy practice in Canada. This study examines the structural changes that have been made in community pharmacies that have adopted a pharmaceutical care model/program. A data collection instrument was developed which included the Community Pharmacy Structural Elements Questionnaire (CPSEQ) and the Behavioral Pharmaceutical Care Scale (BPCS). The CPSEQ was used to gather information regarding structural changes made in community pharmacies and the BPCS was used to gather information regarding pharmacists' efforts towards the provision of pharmaceutical care. The data collection instruments were administered to 261 community pharmacists across Canada who had been identified to have been affiliated with a pharmaceutical care model/program and were likely to have implemented pharmaceutical care practices. The instrument was also administered to a reference group of 197 community pharmacists who were not affiliated to any pharmaceutical care model/program. The information gathered was used to determine the most frequent structural elements observed in community pharmacies that had implemented a pharmaceutical care model/program and in progressive community pharmacies that were actively providing pharmaceutical care. The exploratory analysis revealed the presence of progressive community pharmacy practices in Canada that were actively making structural changes and providing pharmaceutical care. Among the structural changes that were consistently reported in these community pharmacy practices were re-organization of pharmacists' duties, re-organization of pharmacy technicians' duties, formal training program for pharmacists, on-the-job training for pharmacy technicians, incorporation of a private or semi-private counselling room, and incorporation of audio-visual educational equipment.

description: We report the detection, from FUSE data, of phosphorus in the atmospheres of GD71 and two similar DA white dwarfs. This is the first detection of a trace metal in the photosphere of the spectrophotometric standard star GD71. Collectively, these objects represent the coolest DA white dwarfs in which photospheric phosphorus has been observed. We use a grid of homogeneous non-LTE synthetic spectra to measure abundances of[P/H]=-8.57 +0.09 -0.13, -8.70 +0.23 -0.37 and -8.36 +0.14 -0.19 in GD71, RE J1918+595 and RE J0605-482 respectively. At the observed level we find phosphorus has no significant impact on the overall energy distribution of GD71. We explore possible mechanisms responsible for the presence of this element in these stars, concluding that the most likely is an interplay between radiative levitation and gravitational settling but possibly modified by weak mass loss.

description: A black hole can be regarded as a thermodynamic system described by a grand canonical ensemble. In this paper, we study the Bekenstein-Hawking entropy of higher-dimensional rotating black holes using the Euclidean path-integral method of Gibbons and Hawking. We give a general proof demonstrating that ignoring quantum corrections, the Bekenstein-Hawking entropy is equal to one-fourth of its horizon area for general higher-dimensional rotating black holes.

description: Common Vulnerabilities and Exposures database (CVE) is one of the largest publicly available source of software and hardware vulnerability data and reports. In this work we analyze the CVE database in the context of IoT device and system vulnerabilities. We introduce a real-world based classification of IoT systems. Then, we employ a SVM algorithm on selected subset of CVE database to classify "new" vulnerability records in this framework. The subset of interest consists of records that describe vulnerabilities of potential IoT devices of different applications, such as: home, industry, mobile controllers, networking, etc. The purpose of the classification is to develop and test an automatic system for recognition of vulnerable IoT devices and to test completes, sufficiency and reliability of CVE data in this respect.

description: Herein, the interaction of the fourth-generation fluoroquinolone antibiotic drug, moxifloxacin hydrochloride (MFH), which is extensively used for the treatment of wider ranges of bacterial infections, like pneumonia, endocarditis, tuberculosis, and other complicated dermal lesions, and cetyltrimethylammonium bromide (CTAB, a cationic surfactant) has been observed by conductivity method in aqueous, alcoholic (C2H5OH, C3H7OH-2), and diol (C2H4(OH)2, C3H6(OH)2) solutions. For all of the MFH + CTAB cases studied, the appearance of a critical micelle concentration (cmc) demonstrated that the micellar system is dependent on the variation of temperature and the concentration of different additives. A change in the value of cmc manifests the existence of strong interaction prevailing amongst MFH and CTAB molecules. In presence of alcohols/diols, the value of cmc for the MFH + CTAB system was found higher compared to those values obtained for the MFH + CTAB system carried out in H2O, which indicates a favourable micellization process. The values of counter-ion dissociation were also found to be dependent on temperature. The ΔGmo values were observed negative, which, again, manifests a spontaneous micellization process. The free energy of transfer (ΔGm,tro) and the enthalpy–entropy compensation were also calculated and discussed.

description: Supply management has been shown to increase the price of milk. Technological change has induced (and allowed) processors to substitute alternative inputs, many of which can be imported tariff-free, for the traditional ingredients to lower costs and maximize profit. Meanwhile, there has been a great deal of consolidation in the dairy processing industry. We analyse the effect of these trends on cheese quality by measuring the increase in casein imports. Results suggest that supply management is negatively affecting cheese quality, by increasing casein imports due to the higher milk price. Furthermore, we were able to calculate that approximately 9.8% of specialty cheese is produced used casein. A 22% ad valorem tariff is needed to drive casein imports down to zero.

description: Axion dark matter (DM) may convert to radio-frequency electromagnetic radiation in the strong magnetic fields around neutron stars. The radio signature of such a process would be an ultra-narrow spectral peak at a frequency determined by the mass of the axion particle. We analyze data we collected from the Robert C. Byrd Green Bank Telescope in the L-band and the Effelsberg 100-m Telescope in the L-Band and S-band from a number of sources expected to produce bright signals of axion-photon conversion, including the Galactic Center of the Milky Way and the nearby isolated neutron stars RX J0720.4-3125 and RX J0806.4-4123. We find no evidence for axion DM and are able to set some of the strongest constraints to-date on the existence of axion DM in the highly-motivated mass range between ~5-11 $μ$eV.

description: Dense low mass cores in nearby clouds like Taurus and Auriga are some of the simplest sites currently forming stars like our Sun. Because of their simplicity and proximity, dense cores offer the clearest view of the different phases of star formation, in particular the conditions prior to the onset of gravitational collapse. Thanks to the combined analysis of the emission from molecular lines and the emission/absorption from dust grains, the last several years have seen a very rapid progress in our understanding of the structure and chemical composition of starless cores. Previous contradictions between molecular tracers are now understood to arise from core chemical inhomogeneities, which are caused by the selective freeze out of molecules onto cold dust grains. The analysis of the dust emission and absorption, in addition, has allowed us to derive accurate density profiles, and has made finally possible to carry out self consistent modeling of the internal structure of starless cores. In this paper I briefly review the evolution of core studies previous to the current golden age, and show how multi-tracer emission can now be modeled in a systematic manner. Finally I show how we can start to reconstruct the early history of core formation taking advantage of the chemical changes in the gas.
