description: We report the discovery of thermal X-ray emission from the youngest Galactic supernova remnant G1.9+0.3, from a 237-ks Chandra observation. We detect strong K-shell lines of Si, S, Ar, Ca, and Fe. In addition, we detect a 4.1 keV line with 99.971% confidence which we attribute to 44Sc, produced by electron capture from 44Ti. Combining the data with our earlier Chandra observation allows us to detect the line in two regions independently. For a remnant age of 100 yr, our measured total line strength indicates synthesis of $(1 - 7) \times 10^{-5}$ solar masses of 44Ti, in the range predicted for both Type Ia and core-collapse supernovae, but somewhat smaller than the $2 \times 10^{-4}$ solar masses reported for Cas A. The line spectrum indicates supersolar abundances. The Fe emission has a width of about 28,000 km/s, consistent with an age of about 100 yr and with the inferred mean shock velocity of 14,000 km/s deduced assuming a distance of 8.5 kpc. Most thermal emission comes from regions of lower X-ray but higher radio surface brightness. Deeper observations should allow more detailed spatial mapping of scandium, with significant implications for models of nucleosynthesis in Type Ia supernovae.

description: We study, both theoretically and experimentally, the occurrence of topological defects in polariton superfluids in the optical parametric oscillator (OPO) regime. We explain in terms of local supercurrents the deterministic behaviour of both onset and dynamics of spontaneous vortex-antivortex pairs generated by perturbing the system with a pulsed probe. Using a generalised Gross-Pitaevskii equation, including photonic disorder, pumping and decay, we elucidate the reason why topological defects form in couples and can be detected by direct visualizations in multi-shot OPO experiments.

description: Molecular platinum fluorides PtFn, n=1–6, are prepared by two different routes, photo-initiated fluorine elimination from PtF6 embedded in solid noble-gas matrices, and the reaction of elemental fluorine with laser-ablated platinum atoms. IR spectra of the reaction products isolated in rare-gas matrices under cryogenic conditions provide, for the first time, experimental vibrational frequencies of molecular PtF3, PtF4 and PtF5. Photolysis of PtF6 enabled a highly efficient and almost quantitative formation of molecular PtF4, whereas both PtF5 and PtF3 were formed simultaneously by subsequent UV irradiation of PtF4. The vibrational spectra of these molecular platinum fluorides were assigned with the help of one- and two-component quasirelativistic DFT computation to account for scalar relativistic and spin–orbit coupling effects. Competing Jahn-Teller and spin–orbit coupling effects result in a magnetic bistability of PtF4, for which a spin-triplet (3B2g, D2h) coexists with an electronic singlet state (1A1g, D4h) in solid neon matrices.

description: In this work we present two correspondences between the massless Gross-Neveu model with one or two coupling constants in 1+1 dimensions and nonrelativistic field theories in 3+1 dimensions. It is shown that on a mean-field level the massless Gross-Neveu model can be mapped onto BCS theory provided that translational invariance of the condensate is assumed. The generalized massless Gross-Neveu model with two coupling constants is mapped onto a quasi one-dimensional extended Hubbard model used in the description of spin-Peierls systems. It is shown that the particle hole symmetry of the Hubbard model implies self-consistency of the condensate. The dimensional reduction allows an identification of the phase diagrams of the models.

description: Non-sericin (NS) extract was produced from the ethanolic extract of Bombyx mori silk cocoons. This extract is composed of both carotenoids and flavonoids. Many of these compounds are composed of substances of poor aqueous solubility. Thus, this study focused on the development of a carrier system created from biocompatible and biodegradable materials to improve the biological activity of NS extracts. Accordingly, NS was incorporated into human serum albumin template particles with MnCO3 (NS-HSA MPs) by loading NS into the preformed HAS-MnCO3 microparticles using the coprecipitation crosslinking dissolution technique (CCD-technique). After crosslinking and template dissolution steps, the NS loaded HSA particles are negatively charged, have a size ranging from 0.8 to 0.9 mu m, and are peanut shaped. The degree of encapsulation efficiency ranged from 7% to 57% depending on the initial NS concentration and the steps of adsorption. In addition, NS-HSA MPs were taken up by human lung adenocarcinoma (A549 cell) for 24 h. The promotion of cellular uptake was evaluated by flow cytometry and the results produced 99% fluorescent stained cells. Moreover, the results from CLSM and 3D fluorescence imaging confirmed particle localization in the cells. Interestingly, NS-HSA MPs could not induce inflammation through nitric oxide production from macrophage RAW264.7 cells. This is the first study involving the loading of non-sericin extracts into HSA MPs by CCD technique to enhance the bioavailability and biological effects of NS. Therefore, HSA MPs could be utilized as a carrier system for hydrophobic substances targeting cells with albumin receptors.

description: In our complex world today almost all critical infrastructures are interdependent and thus vulnerable to many different external and internal risks. To protect them against the greatest risks, a well-functioning risk management process is required to develop appropriate safety and security strategies. There are many wellestablished risk analysis methods existing. They predominantly apply empirical models and statistical data to quantify the risks. Within the realms of natural or aleatory risks this approach is considered suitable and functional. However, it could be a fatal flaw to apply such conventional, history-orientated models in order to assess risks that arise from intelligent adversaries such as terrorists, criminals or competitors. Approaches of classic risk analysis generally describe adversaries’ choices as random variables, thus excluding the adversaries’ behaviour and ability to adapt to security strategies. One possibility for considering human behaviour when analysing risks is the recourse to game theory. Game theory is the paradigmatic framework for strategic decision-making when two or more rational decision-makers (intelligent adversaries) are involved in cooperative or conflictive decision situations. In our study we propose an approach for combining a classic risk analysis method with a game-theoretic approach. Using a defenderoffender game as a basis, we simulate, exemplary for a terrorist attack against public transport, the behaviour and reactions (to applied security strategies of the defender) of a rational player acting as an adversary. Although risk analysis and game theory are very different methodologies, we show that linking them can significantly improve the quality of forecasts and risk assessments. If the behaviour and reactions of intelligent adversaries need to be considered, our approach contributes to enhance security through improving the allocation of scarce financial resources.

description: The natural mineral azurite Cu$_3$(CO$_3$)$_2$(OH)$_2$ is a frustrated magnet displaying unusual and controversially discussed magnetic behavior. Motivated by the lack of a unified description for this system, we perform a theoretical study based on density functional theory as well as state-of-the-art numerical many-body calculations. We propose an effective generalized spin-1/2 diamond chain model which provides a consistent description of experiments: low-temperature magnetization, inelastic neutron scattering, nuclear magnetic resonance measurements, magnetic susceptibility as well as new specific heat measurements. With this study we demonstrate that the balanced combination of first principles with powerful many-body methods successfully describes the behavior of this frustrated material.

description: Recently, Gaberdiel and Gopakumar proposed that the two-dimensional WA_{N-1} minimal model conformal field theory in the large N 't Hooft limit is dual to the higher spin theories on the three-dimensional AdS space with two complex scalars. In this paper, we examine this proposal for the WD_{N/2} and WB_{(N-1)/2} minimal models initiated by Fateev and Lukyanov in 1988. By analyzing the renormalization group flows on these models, we find that the gravity duals in AdS space are higher spin theories coupled to two equally massive real scalar fields. We also describe the large N 't Hooft limit for the minimal model of the second parafermion theory.

description: At present deconstruction project planning and related research focus mainly on economic issues including costs for equipment, workers and material disposal. Nevertheless, deconstruction of buildings can have major impacts on the local environment in terms of noise, dust and vibrations. Usually these environmental concerns are not included in deconstruction planning. But they can be harmful for humans, animals and the surrounding built environment. Analyses of different deconstruction techniques show major differences in noise, dust and vibrations. To use this potential to mitigate local environmental impacts, principals and deconstruction managers have to perform environmental conscious detailed deconstruction planning. In support of balancing these environmental issues with economic and technical aspects, a multi-criteria decision approach can help in the planning phase. In this paper a combination of the multi-criteria decision analysis methods Analytic Hierarchy Process (AHP) and Multi-Attribute Value Theory (MAVT) is embedded in a system for the planning of deconstruction projects based on deconstruction techniques applied to single building components. The structure of this system is described in detail, encompassing the procedure of modelling the overall planning and decision making process as well as the application of the decision making logic. Expert knowledge and experimental noise, dust and vibration measurements related to different deconstruction techniques form the system database. The system is exemplarily applied to deconstruction planning of a small one-level building. Finally, its possible future practical implementation is addressed.
Developing a Pollution Measuring System to Manage Demolition Projects Complying with Legal Regulations

Publisher: name: Karlsruhe
Year: 2014

description: Demolition and construction processes usually generate pollutions, namely dust, noise and vibration. These pollutions can have a negative impact on human health or the environment. Hence, pollutions are often a strong argument against necessary demolition and building projects. There are legal regulations of pollution control to minimize these impacts. However, usually no measurements and least of all permanent monitoring are performed on site, as pollution measuring is very costly. Often pollutions are only controlled by goodwill of the contractor, who acts upon his experiences and knowledge. To initiate pollution-reducing actions on site, an inexpensive measuring system is developed, which measures and calculates pollutions in real-time. In this paper, the system is described. First the basic system requirements are introduced. Then the systems components and the system buildup are explained in some detail. The system consists of measurement nodes (usually 6-10), which monitor dust, noise and vibrations. These nodes are supposed to be placed around the construction/deconstruction object. An analyzing unit calculates the estimated level of pollution in every important position. The calculated data is sent directly to the operator, since the excavator usually causes major emissions and resulting pollutions can be reduced by adjusting the working process, such as choosing a proper demolition technique or applying pollution protection measures. The aim of this research is to help the contractor and principal to perform construction and demolition work complying with legal regulations by warning them, when limits are exceeded.

description: Excerpts from the report: Given the requirements of the Wholesome Meat Act, as the 1967 revision of Federal Meat Inspection Act is commonly called, the average small meat processor has a choice of four courses of action: remodeling his plant to qualify for certification; building a new plant; confining himself to custom (exempt) work; or going out of business. The need of small operators for assistance with plant design and layout has not gone totally unrecognized. This study was undertaken after the Meat Handling and Facilities Research group of Agricultural Research Service had received a number of requests from processors for assistance with plant design and layout. About 60 small operators were assisted over a 2-year period. Of these, about 40 percent chose to remodel, and the rest chose to build new plants. In addition, architects and builders were assisted in making plans for their customers. The researchers made no attempt to ascertain if any plan represented a sound investment. The project has been evaluated, and the drawings and some of the information derived from it are presented here.

description: This presentation aims to showcase different examples of actions by libraries across Europe on the subject of Open Education, by inviting several librarians to converse on the development of Open Education in their respective countries and the growing collaboration on this subject. From capacity building to national projects, librarians are raising awareness and encouraging the adoption of open educational resources in their institutions. This international discussion will allow educators, policymakers and fellow librarians to have an accurate understanding of the progression of OER and open educational practices in various European countries. While some challenges for the development of open education are met everywhere around the globe, European countries also face specific issues, and seek to resolve them through cooperation. By highlighting librarians who are beginning to take action in the path to openness as well as those who can rely on strong communities and national networks, the presentation will aim to showcase and increase collaboration on an international scale.

description: The electron Bernstein wave (EBW) is typically the only wave in the electron cyclotron (EC) range that can be applied in spherical tokamaks for heating and current drive (H&CD). Spherical tokamaks (STs) operate generally in high-beta regimes, in which the usual EC O- and X- modes are cut-off. In this case, EBWs seem to be the only option that can provide features similar to the EC waves---controllable localized H&CD that can be utilized for core plasma heating as well as for accurate plasma stabilization. The EBW is a quasi-electrostatic wave that can be excited by mode conversion from a suitably launched O- or X-mode; its propagation further inside the plasma is strongly influenced by the plasma parameters. These rather awkward properties make its application somewhat more difficult. In this paper we perform an extensive numerical study of EBW H&CD performance in four typical ST plasmas (NSTX L- and H-mode, MAST Upgrade, NHTX). Coupled ray-tracing (AMR) and Fokker-Planck (LUKE) codes are employed to simulate EBWs of varying frequencies and launch conditions, which are the fundamental EBW parameters that can be chosen and controlled. Our results indicate that an efficient and universal EBW H&CD system is indeed viable. In particular, power can be deposited and current reasonably efficiently driven across the whole plasma radius. Such a system could be controlled by a suitably chosen launching antenna vertical position and would also be sufficiently robust.

description: We study the time evolution of a brane construction that is holographically dual to a strongly coupled gauge theory that dynamically breaks a global symmetry through the generation of an effective composite Higgs vev. The D3/D7 system with a background magnetic field or non-trivial gauge coupling (dilaton) profile displays the symmetry breaking. We study motion of the D7 brane in the background of the D3 branes. For small field inflation in the field theory the effective Higgs vev rolls from zero to the true vacuum value. We study what phenomenological dilaton profile generates the slow rolling needed, hence learning how the strongly coupled gauge theory's coupling must run. We note that evolution of our configuration in the holographic direction, representing the phyiscs of the strong interactions, can provide additional slowing of the roll time. Inflation seems to be favoured if the coupling changes by only a small amount or very gently. We speculate on how such a scenario could be realized away from N=4 gauge theory, for example, in a walking gauge theory.

A Global Turbulence Model for Neutrino-Driven Convection in Core-Collapse Supernovae

Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Simulations of core-collapse supernovae (CCSNe) result in successful explosions once the neutrino luminosity exceeds a critical curve, and recent simulations indicate that turbulence further enables explosion by reducing this critical neutrino luminosity. We propose a theoretical framework to derive this result and take the first steps by deriving the governing mean-field equations. Using Reynolds decomposition, we decompose flow variables into background and turbulent flows and derive self-consistent averaged equations for their evolution. As basic requirements for the CCSN problem, these equations naturally incorporate steady-state accretion, neutrino heating and cooling, non-zero entropy gradients, and turbulence terms associated with buoyant driving, redistribution, and dissipation. Furthermore, analysis of two-dimensional (2D) CCSN simulations validate these Reynolds-averaged equations, and we show that the physics of turbulence entirely accounts for the differences between 1D and 2D CCSN simulations. As a prelude to deriving the reduction in the critical luminosity, we identify the turbulent terms that most influence the conditions for explosion. Generically, turbulence equations require closure models, but these closure models depend upon the macroscopic properties of the flow. To derive a closure model that is appropriate for CCSNe, we cull the literature for relevant closure models and compare each with 2D simulations. These models employ local closure approximations and fail to reproduce the global properties of neutrino-driven turbulence. Motivated by the generic failure of these local models, we propose an original model for turbulence which incorporates global properties of the flow. This global model accurately reproduces the turbulence profiles and evolution of 2D CCSN simulations.

Interpreting gentrification in China : the rising consumer society and inequality in the state-facilitated redevelopment of the central city of Chengdu
Creators: name: Yang, Qinran
Publisher: name: University of British Columbia
Year: 2017

description: Currently, scholars are debating the epistemological limits of the concept of gentrification as a representation of global urban experiences. The thesis addresses this global debate from the perspective of Chinese urbanisation. In China, socio-spatial upgrading and displacement, which normally define a gentrification process, are most likely prompted by state-facilitated urban redevelopment. The dissertation questions why and how state action attracts middle-class newcomers to the inner city and penalises or reconciles working-class residents. With the research focused on urban China, the thesis also contributes to conceptual and methodological issues on gentrification research on a global scale. A meso-level approach is taken to trace the gentrification process through both structural tendencies and grounded empirical processes in the inner city of Chengdu from 2000 to 2010. Analysis at the two scales in conjunction accomplishes an examination of the existence of gentrification and the explanation of regularities within it. In Chengdu, the state’s mobilisation in developmental strategies concentrating on the built environment allows the case study to make new claims for gentrification knowledge for non-Western cities. Mixed methods, including statistical and spatial analysis, institutional analysis, and extensive ethnographic study, are used to investigate gentrification from a structural perspective, a historical perspective, and as a grounded process within the neighbourhood. The research reveals that state actions in urban redevelopment direct the cultural and behavioural changes of the middle-class newcomers, so that they are compatible with state strategies in modernisation and real estate boosterism. Working-class groups face varying outcomes in residential relocation. Overall, the process reflects state hegemony over societies that comprise subaltern cultures in the city, incorporating legal and propertied citizens into the frame of consumerism while disenfranchising rural-urban migrants. The study unravels how state domination in urban redevelopment drives social change towards a consumer society, which sharpens social inequities but also, ironically, rebuilds the collectivist ideology from one centring on production to one pressing the ideology and practices of consumption. So an overall gentrification process is formulated in Chengdu, which retains complexities and contingencies in localities. On a broader scale, the thesis urges a meso-level approach to gentrification research in other cities.

description: Autocatalysis is a fundamental concept, used in a wide range of domains. From the most general definition of autocatalysis, that is a process in which a chemical compound is able to catalyze its own formation, several different systems can be described. We detail the different categories of autocatalyses, and compare them on the basis of their mechanistic, kinetic, and dynamic properties. It is shown how autocatalytic patterns can be generated by different systems of chemical reactions. The notion of autocatalysis covering a large variety of mechanistic realisations with very similar behaviors, it is proposed that the key signature of autocatalysis is its kinetic pattern expressed in a mathematical form.

description: Collaborative decision-making is widely understood as a democratic corrective to top-down forms of environmental management; it is a way in which citizens can contribute local knowledge to the policy process and have a more direct role in shaping policies and rules that affect them and their environments. However, while the democratic virtues of collaborative governance are often asserted, they are rarely evidenced; this leaves claims of democratic empowerment open to question. This study used a longitudinal survey of three New Zealand regions (n = 1350) to identify whether major multi-year investments in collaborative decision-making (2012-2018) are leading to increased public confidence in the effectiveness, responsiveness and fairness of water management institutions.
Residents in collaborative catchments were found to have scores that were statistically indistinguishable from residents of non-collaborative catchments on management effectiveness, perceived agreement about water management, and fairness. Collaborative catchment residents did assign higher scores for water management responsiveness than did other residents, but the size of this difference was small compared to the effects of gender, ethnicity, region and level of individuals' prior engagement in water management. Despite major investments in collaborative community decision-making exercises, community confidence in the legitimacy, fairness and effectiveness of environmental management has not improved over the four years documented in our surveys.Researchers and practitioners should focus on developing ways to assess - and realise - the democratic benefits of collaborative decision-making for water.

description: The Ecodesign and Labelling directives are key policy measures to increase energy efficiency in Europe. In view of the extension of Ecodesign and Labelling to further products as well as the revision of the current implementing directives, it is essential to evaluate the potential energy savings, takin g into account different paths of technological development and diffusion. Our study uses bottom - up modelling to evaluate the long - term saving potentials of Ecodesign and Label ling for residential appliances (including large appliances, cooking and ICT), lighting and air conditioning. The household end - uses that are affected by the legislation are implemented in the model in a disaggregated way. The model is designed as a vintage stock approach and based on the simulation of consumer activities as well as technological trajectories. We model the electricity demand of household end - uses in the EU - 27 by country and compare various scenarios. Our Reference Scenario reflects the electricity demand of household end - uses without any policy measures implemented after 2008. Our current Policy Scenario includes all implementing directives that are currently in force and assumes that the sensitivity of consumers to the total cost of ownership remains at the currently witnessed level. Finally, our LLCC Scenario explores the potential energy savings assuming that consumers choose the economically favourable options considering the total cost of ownership.

description: Using a two-channel Anderson model, we develop a theory of composite pairing in the 115 family of heavy fermion superconductors that incorporates the effects of f-electron valence fluctuations. Our calculations introduce "symplectic Hubbard operators": an extension of the slave boson Hubbard operators that preserves both spin rotation and time-reversal symmetry in a large N expansion, permitting a unified treatment of anisotropic singlet pairing and valence fluctuations. We find that the development of composite pairing in the presence of valence fluctuations manifests itself as a phase-coherent mixing of the empty and doubly occupied configurations of the mixed valent ion. This effect redistributes the f-electron charge within the unit cell. Our theory predicts a sharp superconducting shift in the nuclear quadrupole resonance frequency associated with this redistribution. We calculate the magnitude and sign of the predicted shift expected in CeCoIn_5.

A Third Hot White Dwarf Companion Detected by Kepler

description: We have found a system listed in the Kepler Binary Catalog (3.273 day period; Prsa et al. 2010) that we have determined is comprised of a low-mass, thermally-bloated, hot white dwarf orbiting an A star of about 2.3 solar masses. In this work we designate the object, KIC 10657664, simply as KHWD3. We use the transit depth of ~0.66%, the eclipse depth of ~1.9%, and regular smooth periodic variations at the orbital frequency and twice the orbital frequency to analyze the system parameters. The smooth periodic variations are identified with the classical ellipsoidal light variation and illumination effects, and the newly utilized Doppler boosting effect. Given the measured values of R/a and inclination angle of the binary, both the ELV and DB effects are mostly sensitive to the mass ratio, q = M_2/M_1, of the binary. The two effects yield values of q which are somewhat inconsistent - presumably due to unidentified systematic effects - but which nonetheless provide a quite useful set of possibilities for the mass of the white dwarf (either 0.18 +/- 0.03 M_Sun or 0.37 +/- 0.08 M_Sun). All of the other system parameters are determined fairly robustly. In particular, we show that the white dwarf has a radius of 0.15 +/- 0.01 R_Sun which is extremely bloated over the radius it would have as a fully degenerate object, and an effective temperature T_eff = 14,100 +/- 350 K. Binary evolution scenarios and models for this system are discussed. We suggest that the progenitor binary was comprised of a primary of mass ~2.2 M_Sun (the progenitor of the current hot white dwarf) and a secondary of mass ~1.4 M_Sun (the progenitor of the current A star in the system). We compare this new system with three other white dwarfs in binaries that likely were formed via stable Roche-lobe overflow (KOI-74, KOI-81, and Regulus).

Cosmological implications of interacting polytropic gas dark energy model in non-flat universe

description: The polytropic gas model is investigated as an interacting dark energy scenario. The cosmological implications of the model including the evolution of EoS parameter $w_Λ$, energy density $Ω_Λ$ and deceleration parameter $q$ are investigated. We show that, depending on the parameter of model, the interacting polytropic gas can behave as a quintessence or phantom dark energy. In this model, the phantom divide is crossed from below to up. The evolution of $q$ in the context of polytropic gas dark energy model represents the decelerated phase at the early time and accelerated phase later. The singularity of this model is also discussed. Eventually, we establish the correspondence between interacting polytropic gas model with tachyon, K-essence and dilaton scalar fields. The potential and the dynamics of these scalar field models are reconstructed according to the evolution of interacting polytropic gas.

Non-linear matter power spectrum from Time Renormalisation Group: efficient computation and comparison with one-loop

description: We address the issue of computing the non-linear matter power spectrum on mildly non-linear scales with efficient semi-analytic methods. We implemented M. Pietroni's Time Renormalization Group (TRG) method and its Dynamical 1-Loop (D1L) limit in a numerical module for the new Boltzmann code CLASS. Our publicly released module is valid for LCDM models, and optimized in such a way to run in less than a minute for D1L, or in one hour (divided by number of nodes) for TRG. A careful comparison of the D1L, TRG and Standard 1-Loop approaches reveals that results depend crucially on the assumed initial bispectrum at high redshift. When starting from a common assumption, the three methods give roughly the same results, showing that the partial resumation of diagrams beyond one loop in the TRG method improves one-loop results by a negligible amount. A comparison with highly accurate simulations by M. Sato & T. Matsubara shows that all three methods tend to over-predict non-linear corrections by the same amount on small wavelengths. Percent precision is achieved until k~0.2 h/Mpc for z>2, or until k~0.14 h/Mpc at z=1.

description: Excerpts from the report: This publication is part of an overall program by the Agricultural Research Service to provide technical assistance to shippers and carriers in an effort to help increase U.S. agricultural exports. European transport equipment and regulations governing its use are often different from those in the United States. Shippers and carriers should be aware of these differences so their exports will (1) be properly packaged; (2) have adequate refrigeration; (3) be correctly routed : (4) receive special services, if needed; and (5) be of an acceptable load size and weight. The information contained in this bulletin is intended as a guide for shippers and carriers to alert, them to specific problem areas. The information should be updated periodically to comply with frequent changes in foreign regulations as they occur. Shippers should always verify regulations applicable to specific destinations with their ocean carrier.
Multipartite non-locality in a thermalized Ising spin-chain

description: We study multipartite correlations and non-locality in an isotropic Ising ring under transverse magnetic field at both zero and finite temperature. We highlight parity-induced differences between the multipartite Bell-like functions used in order to quantify the degree of non-locality within a ring state and reveal a mechanism for the passive protection of multipartite quantum correlations against thermal spoiling effects that is clearly related to the macroscopic properties of the ring model.

description: The workshop covered naming conventions for folders and files, file versioning, and data structuring for storage and publishing. It's not surprising that some projects still have no file and folder naming conventions. It is critical that each project team agrees on how to name their files and folders. However, the difficulty arises from the fact that scientists come from a variety of backgrounds, and everyone believes that their file naming style is the best and that no one should change it.
What we believe is best is for project leaders to develop file and folder naming rules with team members and explain the benefits of such naming rules to the team in order to pique team members' interest in adhering to the rules.
The advantages of following file naming conventions are twofold: To begin with, your files will be machine and human readable, and file search and sorting will be very simple. Setting or adhering to file naming conventions will allow you to be well organised as an individual. You will be able to easily identify files and group files with similar contents together. Last but not least, other team members will understand what your research is about, which leads to greater appreciation.
