description: A study of factors proposed to affect metallothionein-3 (MT3) function was carried out to elucidate the opaque role MT3 plays in human metalloneurochemistry. Gene expression of Mt2 and Mt3 was examined in tissues extracted from the dentate gyrus of mouse brains and in human neuronal cell cultures. The whole-genome gene expression analysis identified significant variations in the mRNA levels of genes associated with zinc homeostasis, including Mt2 and Mt3. Mt3 was found to be the most differentially expressed gene in the identified groups, pointing to the existence of a factor, not yet identified, that differentially controls Mt3 expression. To examine the expression of the human metallothioneins in neurons, mRNA levels of MT3 and MT2 were compared in BE(2)C and SH-SY5Y cell cultures treated with lead, zinc, cobalt, and lithium. MT2 was highly upregulated by Zn2+ in both cell cultures, while MT3 was not affected, and no other metal had an effect on either MT2 or MT3.

description: We present new z~8 galaxy candidates from a search over ~95 arcmin^2 of WFC3/IR data, tripling the previous search area for bright z~8 galaxies. Our analysis uses newly acquired WFC3/IR imaging data from the CANDELS Multi-Cycle Treasury program over the GOODS South field. These new data are combined with existing deep optical ACS imaging to search for relatively bright (M_UV < -19.5 mag) z~8 galaxy candidates using the Lyman Break technique. These new candidates are used to determine the bright end of the UV luminosity function (LF) of star-forming galaxies at z~8. To minimize contamination from lower redshift galaxies, we make full use of all optical ACS data and impose strict non-detection criteria based on an optical chi^2_opt flux measurement. In the whole search area we identify 16 candidate z~8 galaxies, spanning a magnitude range H_160 = 25.7-27.9 mag. The new data show that the UV LF is a factor ~1.7x lower at M_UV < -19.5 mag than determined from the HUDF09 and ERS data alone. Combining this new sample with the previous candidates from the HUDF09 and ERS data allows us to perform the most accurate measurement of the z~8 UV LF yet. Schechter function fits to the combined data result in a best-fit characteristic magnitude of M*(z=8) = -20.04+-0.46 mag. The faint-end slope is very steep, though quite uncertain, with alpha = -2.06+-0.32. A combination of wide area data with additional ultra-deep imaging will be required to significantly reduce the uncertainties on these parameters in the future.

description: Peculiar velocities are an important probe of the growth rate of mass density fluctuations in the Universe. Most previous studies have focussed exclusively on measuring peculiar velocities at intermediate ($0.2 < z < 1$) redshifts using statistical redshift-space distortions. Here we emphasize the power of peculiar velocities obtained directly from distance measurements at low redshift ($z \lesssim 0.05$), and show that these data break the usual degeneracies in the Ω_{m,0} -- $σ_{8,0}$ parameter space. Using only peculiar velocity data, we find $Ω_{m,0} = 0.259\pm0.045$ and $σ_{8,0} = 0.748\pm0.035$. Fixing the amplitude of fluctuations at very high redshift using observations of the Cosmic Microwave Background (CMB), the same data can be used to constrain the growth index $γ$, with the strongest constraints coming from peculiar velocity measurements in the nearby Universe. We find $γ= 0.619\pm 0.054$, consistent with LCDM. Current peculiar velocity data already strongly constrain modified gravity models, and will be a powerful test as data accumulate.

description: Fine-scale agricultural statistics are an important tool for understanding trends in food production and their associated drivers, yet these data are rarely collected in smallholder systems. These statistics are particularly important for smallholder systems given the large amount of fine-scale heterogeneity in production that occurs in these regions. To overcome the lack of ground data, satellite data are often used to map fine-scale agricultural statistics. However, doing so is challenging for smallholder systems because of (1) complex sub-pixel heterogeneity; (2) little to no available calibration data; and (3) high amounts of cloud cover as most smallholder systems occur in the tropics. We develop an automated method termed the MODIS Scaling Approach (MSA) to map smallholder cropped area across large spatial and temporal scales using MODIS Enhanced Vegetation Index (EVI) satellite data. We use this method to map winter cropped area, a key measure of cropping intensity, across the Indian subcontinent annually from 2000–2001 to 2015–2016. The MSA defines a pixel as cropped based on winter growing season phenology and scales the percent of cropped area within a single MODIS pixel based on observed EVI values at peak phenology. We validated the result with eleven high-resolution scenes (spatial scale of 5 × 5 m2 or finer) that we classified into cropped versus non-cropped maps using training data collected by visual inspection of the high-resolution imagery. The MSA had moderate to high accuracies when validated using these eleven scenes across India (R2 ranging between 0.19 and 0.89 with an overall R2 of 0.71 across all sites). This method requires no calibration data, making it easy to implement across large spatial and temporal scales, with 100% spatial coverage due to the compositing of EVI to generate cloud-free data sets. The accuracies found in this study are similar to those of other studies that map crop production using automated methods and use no calibration data. To aid research on agricultural production at fine spatial scales in India, we make our annual winter crop maps from 2000–2001 to 2015–2016 at 1 × 1 km2 produced in this study publically available through the NASA Socioeconomic Data and Applications Center (SEDAC) hosted by the Center for International Earth Science Information Network (CIESIN) at Columbia University. We also make our R script available since it is likely that this method can be used to map smallholder agriculture in other regions across the globe given that our method performed well in disparate agro-ecologies across India.

description: It is well known that current spectroscopic determinations of the chemical composition of the Sun are starkly at odds with the metallicity implied by helioseismology. We investigate whether the discrepancy may be due to conversion of photons to a new light boson in the solar photosphere. We examine the impact of particles with axion-like interactions with the photon on the inferred photospheric abundances, showing that resonant axion-photon conversion is not possible in the region of the solar atmosphere in which line-formation occurs. Although non-resonant conversion in the line-forming regions can in principle impact derived abundances, constraints from axion-photon conversion experiments rule out the couplings necessary for these effects to be detectable. We show that this extends to hidden photons and chameleons (which would exhibit similar phenomenological behaviour), ruling out known theories of new light bosons as photospheric solutions to the solar abundance problem.
description: 11 pages, PDFLaTeX. v2: Major revision. Inclusion of refractive index effect on photon-ALP conversion strengthens our conclusion that such an effect cannot explain the solar abundance problem with a coupling allowed by experimental axion-like particle searches. We now include a discussion of chameleons and hidden photons, with similar conclusions

description: This article presents a soft pneumatic bending actuator using a magnetically assisted bilayer composite composed of silicone polymer and ferromagnetic particles. Bilayer composites were fabricated by mixing ferromagnetic particles to a prepolymer state of silicone in a mold and asymmetrically distributed them by applying a strong non-uniform magnetic field to one side of the mold during the curing process. The biased magnetic field induces sedimentation of the ferromagnetic particles toward one side of the structure. The nonhomogeneous distribution of the particles induces bending of the structure when inflated, as a result of asymmetric stiffness of the composite. The bilayer composites were then characterized with a scanning electron microscopy and thermogravimetric analysis. The bending performance and the axial expansion of the actuator were discussed for manipulation applications in soft robotics and bioengineering. The magnetically assisted manufacturing process for the soft bending actuator is a promising technique for various applications in soft robotics.

description: Given knowledge at the time, the recent 2015–2016 zika virus (ZIKV) epidemic probably could not have been predicted. Without the prior knowledge of ZIKV being already present in South America, and given the lack of understanding of key epidemiologic processes and long-term records of ZIKV cases in the continent, the best related prediction could be carried out for the potential risk of a generic Aedes-borne disease epidemic. Here we use a recently published two-vector basic reproduction number model to assess the predictability of the conditions conducive to epidemics of diseases like zika, chikungunya, or dengue, transmitted by the independent or concurrent presence of Aedes aegypti and Aedes albopictus. We compare the potential risk of transmission forcing the model with the observed climate and with state-of-the-art operational forecasts from the North American Multi Model Ensemble (NMME), finding that the predictive skill of this new seasonal forecast system is highest for multiple countries in Latin America and the Caribbean during the December-February and March-May seasons, and slightly lower—but still of potential use to decision-makers—for the rest of the year. In particular, we find that above-normal suitable conditions for the occurrence of the zika epidemic at the beginning of 2015 could have been successfully predicted at least 1 month in advance for several zika hotspots, and in particular for Northeast Brazil: the heart of the epidemic. Nonetheless, the initiation and spread of an epidemic depends on the effect of multiple factors beyond climate conditions, and thus this type of approach must be considered as a guide and not as a formal predictive tool of vector-borne epidemics.

Decoherence dynamics of geometric measure of quantum discord and measurement-induced nonlocality for noninertial observers at finite temperature
Creators: name: Ramzan, M.
Publisher: name: arXiv
Year: 2012

description: Quantum discord quantifies the total non-classical correlations in mixed states. It is the difference between total correlation, measured by quantum mutual information, and the classical correlation. Another step forward towards the quantification of quantum discord was by Dakic, Vedral, and Brukner [Phys. Rev. Lett. 105,190502 (2010)] who introduced the geometric measure of quantum discord (GMQD) and derived an explicit formula for a two-qubit state. Recently, Luo and Fu [Phys. Rev. Lett. 106, 120401 (2011)] introduced measurement-induced nonlocality (MIN) as a measure of nonlocality for a bipartite quantum system. The dynamics of GMQD is recently considered by Song et al. [arXiv: quant/ph.1203.3356] and Zhang et al. [Eur. Phys. J. D 66, 34 (2012)] for inertial observers. However, the topic requires due attention in noninertial frames, particularly, from the perspective of MIN. Here I consider X-structured bipartite quantum system in noninertial frames and analyze the decoherence dynamics of GMQD and MIN at finite temperature. The dynamics under the influence of amplitude damping, depolarizing and phase flip channels is discussed. It is worth-noting that initial state entanglement plays an important role in bipartite states. It is possible to distinguish the Bell, Werner and general type initial quantum states using GMQD. Sudden transition in the behaviour of GMQD and MIN occurs depending upon the mean photon number of the local environment. The transition behaviour disappears for larger values of n, i.e. n>0.3. It becomes more prominent, when environmental noise is introduced in the system. ......

Evaluation of the in vivo role of p-glycoprotein in the maintenance of cholesterol homeostasis
Creators: name: Lee, Stephen David
Publisher: name: University of British Columbia
Year: 2012

description: Removal of cholesterol from the body is the final step in reverse cholesterol transport, the process by which excess cholesterol is moved from peripheral tissues to the liver for excretion. Several provocative studies led us to probe the contributions of P-glycoprotein (Pgp), an ATP-dependent transporter with broad range of hydrophobic substrates, to the removal of cholesterol and its bile acid metabolites from the body. We used knockout mice lacking both isoforms of Pgp (Abcb1a⁺/1b⁺) fed test diets containing elevated fat and/or cholesterol to determine if Pgp deletion affects murine cholesterol homeostasis. The knockout mice had the same cholesterol phenotype as wild-type mice, measured by cholesterol absorption, circulating lipoproteins, and hepatic storage of cholesterol. We examined the activation of two key regulatory pathways that maintain cholesterol homeostasis, Sterol Regulatory Element Binding Protein-2 (SREBP-2) and Liver X Receptor (LXR), to determine if the knockout mice maintain cholesterol balance through compensatory mechanisms. The knockout mice had decreased expression of SREBP-2-target genes in the jejunum and increased expression of LXR-target genes in the liver. These perturbations to cholesterol regulatory networks are indirect evidence that the knockout mice lacked a cholesterol efflux mechanism. We evaluated efflux of bile acids from the liver to the gallbladder in mice after nine weeks on the test diets. Knockout mice fed elevated fat or cholesterol had a 30-50% reduction in bile acid efflux capacity compared to wild type mice, suggesting that Pgp contributes to murine bile acid efflux. Subsequent analysis revealed that Pgp did not display specificity for a particular class of bile acids. In summary, we provide evidence that deletion of Pgp did not alter the cholesterol phenotype of mice; however, compensatory shifts in cholesterol regulatory networks maintained homeostasis in the knockout. Additionally, we show that Pgp knockout mice had a reduced capacity to efflux bile acids to the gallbladder. The nature of the changes to the cholesterol regulatory networks and the perturbations to bile acid efflux suggest that Pgp is a non-specific efflux transporter that recognizes both cholesterol and bile acids as substrates.

description: We report a systematic study of the $c$ lattice parameter in the Na$_{x}$CoO$_{2}$ phases versus Na content $x>0.5$, in which sodium always displays ordered arrangements. This allows us to single out the first phase which exhibits an AF magnetic order at a Néel temperature $T_{N}=$22 K which is found to occur for $x\approx 0.77(1)$. Pure samples of this phase have been studied both as aligned powders and single crystals. They exhibit identical $^{23}$Na NMR spectra in which three sets of Na sites could be fully resolved, and are found to display $T$ dependencies of their NMR shifts which scale with each other. This allows us to establish that the $T$ variation of the shifts is due to the paramagnetism of the Co sites with formal charge state larger than 3$^{+}$. The existence of a sodium site with axial charge symmetry and the intensity ratio between the sets of $^{23}$Na lines permits us to reveal that the 2D structure of the Na order corresponds to 10 Na sites on top of a 13 Co sites unit cell, that is with $x=10/13\approx 0.77$. This structure fits with that determined from local density calculations and involves triangles of 3 Na sites located on top of Co sites (so called Na1 sites). The associated ordering of the Na vacancies is quite distinct from that found for $x<0.75$.

description: Group Field Theories (GFT) are quantum field theories over group manifolds; they can be seen as a generalization of matrix models. GFT Feynman graphs are tensor graphs generalizing ribbon graphs (or combinatorial maps); these graphs are dual not only to manifolds. In order to simplify the topological structure of these various singularities, colored GFT was recently introduced and intensively studied since. We propose here a different simplification of GFT, which we call multi-orientable GFT. We study the relation between multi-orientable GFT Feynman graphs and colorable graphs. We prove that tadfaces and some generalized tadpoles are absent. Some Feynman amplitude computations are performed. A few remarks on the renormalizability of both multi-orientable and colorable GFT are made. A generalization from three-dimensional to four-dimensional theories is also proposed.

Newborn infants--Health and hygiene

description: Sleep is a central activity in human adults and characterizes most of the newborn infant life. During sleep, autonomic control acts to modulate heart rate variability (HRV) and respiration. Mechanisms underlying cardiorespiratory interactions in different sleep states have been studied but are not yet fully understood. Signal processing approaches have focused on cardiorespiratory analysis to elucidate this co-regulation. This manuscript proposes to analyze heart rate (HR), respiratory variability and their interrelationship in newborn infants to characterize cardiorespiratory interactions in different sleep states (active vs. quiet). We are searching for indices that could detect regulation alteration or malfunction, potentially leading to infant distress. We have analyzed inter-beat (RR) interval series and respiration in a population of 151 newborns, and followed up with 33 at 1 month of age. RR interval series were obtained by recognizing peaks of the QRS complex in the electrocardiogram (ECG), corresponding to the ventricles depolarization. Univariate time domain, frequency domain and entropy measures were applied. In addition, Transfer Entropy was considered as a bivariate approach able to quantify the bidirectional information flow from one signal (respiration) to another (RR series). Results confirm the validity of the proposed approach. Overall, HRV is higher in active sleep, while high frequency (HF) power characterizes more quiet sleep. Entropy analysis provides higher indices for SampEn and Quadratic Sample entropy (QSE) in quiet sleep. Transfer Entropy values were higher in quiet sleep and point to a major influence of respiration on the RR series. At 1 month of age, time domain parameters show an increase in HR and a decrease in variability. No entropy differences were found across ages. The parameters employed in this study help to quantify the potential for infants to adapt their cardiorespiratory responses as they mature. Thus, they could be useful as early markers of risk for infant cardiorespiratory vulnerabilities.

description: Pt-containing catalysts are currently used commercially to catalyze the conversion of carbon monoxide (CO) and hydrocarbon (HC) pollutants from stationary chemical and petroleum plants. It is well known that Pt-containing catalysts are expensive and have limited availability. The goal of this research is to find alternative and less expensive catalysts to replace Pt for these applications. This study found that niobium oxide (Nb2O5), as a carrier or support for certain transition metal oxides, promotes oxidation activity while maintaining stability, making them candidates as alternatives to Pt. The present work reports that the orthorhombic structure of niobium oxide (formed at 800 °C in air) promotes Co3O4 toward the oxidation of both CO and propane, which are common pollutants in volatile organic compound (VOC) applications. This was a surprising result since this structure of Nb2O5 has a very low surface area (about 2 m2/g) relative to the more traditional Al2O3 support, with a surface area of 150 m2/g. The results reported demonstrate that 1% Co3O4/Nb2O5 has comparable fresh and aged catalytic activity to 1% Pt/γ-Al2O3 and 1% Pt/Nb2O5. Furthermore, 6% Co3O4/Nb2O5 outperforms 1% Pt/Al2O3 in both catalytic activity and thermal stability. These results suggest a strong interaction between niobium oxide and the active component—cobalt oxide—likely by inducing an oxygen defect structure with oxygen vacancies leading to enhanced activity toward the oxidation of CO and propane.

description: In this paper we study, both with theoretical and experimental approach, the effect of iron doping in zirconia. Combining density functional theory (DFT) simulations with the experimental characterization of thin films, we show that iron is in the Fe3+ oxidation state and accordingly that the films are rich in oxygen vacancies (VO). VO favor the formation of the tetragonal phase in doped zirconia (ZrO2:Fe) and affect the density of state at the Fermi level as well as the local magnetization of Fe atoms. We also show that the Fe(2p) and Fe(3p) energy levels can be used as a marker for the presence of vacancies in the doped system. In particular the computed position of the Fe(3p) peak is strongly sensitive to the VO to Fe atoms ratio. A comparison of the theoretical and experimental Fe(3p) peak position suggests that in our films this ratio is close to 0.5. Besides the interest in the material by itself, ZrO2:Fe constitutes a test case for the application of DFT on transition metals embedded in oxides. In ZrO2:Fe the inclusion of the Hubbard U correction significantly changes the electronic properties of the system. However the inclusion of this correction, at least for the value U = 3.3 eV chosen in the present work, worsen the agreement with the measured photo-emission valence band spectra.

Water source, use and cost in a context of poverty : a case study of Tlamacazapa, Guerrero, Mexico
Creators: name: Wenman, Christine
Publisher: name: University of British Columbia
Year: 2012

description: A grounded case study in Tlamacazapa, Guerrero, Mexico is analyzed to document residents’ experiences of obtaining water. Twenty households participated in a detailed journaling exercise over two years to document water access, quantity, sources, uses and costs. The work revealed that the majority of Tlamacazapa residents access insufficient water to meet consumption, sanitation and hygiene needs, let alone productive purposes. Water from most sources is impure, falling short of national standards. Inconsistency in piped water network supply increases vulnerability and reduces health benefits that might otherwise be achieved through infrastructure improvements. Economic and opportunity costs are high both as a ratio to income and in absolute terms illustrating that the poor pay more for water. The resulting situation presents grave health risks for the community. In spite of water contamination and documented low levels of access, Tlamacazapa is considered to have an ‘improved’ water supply according to proxy indicators used both in national and international statistics. These indicators both reflect and perpetuate a focus on physical infrastructure at the expense of the people and processes that that they are intended to serve. The retrenchment of the state in water governance, encouraged through global policy and mirrored in Mexican legislation, has resulted in insufficient support for institutions and capacity building. The case study of Tlamacazapa suggests that the cost of such misguided policy, both in Mexico and globally, will be great both in terms of wasted infrastructure investments and human lives.

description: Graphene can at present be grown at large quantities only by the chemical vapor deposition method, which produces polycrystalline samples. Here, we describe a method for constructing realistic polycrystalline graphene samples for atomistic simulations, and apply it for studying their mechanical properties. We show that cracks initiate at points where grain boundaries meet and then propagate through grains predominantly in zigzag or armchair directions, in agreement with recent experimental work. Contrary to earlier theoretical predictions, we observe normally distributed intrinsic strength (~ 50% of that of the mono-crystalline graphene) and failure strain which do not depend on the misorientation angles between the grains. Extrapolating for grain sizes above 15 nm results in a failure strain of ~ 0.09 and a Young's modulus of ~ 600 GPa. The decreased strength can be adequately explained with a conventional continuum model when the grain boundary meeting points are identified as Griffith cracks.

description: The aim of this paper is to explore the state of the art of Corporate Social Responsibility (CSR) in Islamic culture. This topic is interesting not because Corporate Social Responsibility is a new concept, but because some corporate sustainability reporting values developed in Western Countries, as AA1000 or GRI Standard, are not focused  in Islamic values and beliefs. In fact, Sustainable Development is not a new concept, but it is embedded in the fundamental codes of conduct in Islamic Societies and Laws through Shari’ah (Aman, 2016). The objectives are: a) literature review of Islamic Corportae Social Responsibility and Shari’ah connection with CSR. In particular, descriptive analysis of Islamic Financial Istitution (IFI), which offer alternatives to the commercial activities that Shari'ah prohibits, to answer to the dichotomy between the need to trade with the West and to follow the commands of Islam (Taman, 2011); b) a qualitative comparative analysis between Islamic CSR (ICSR) and conventional CSR c) a documental analysis (Bowen, 2009) of the Islamic network that implements CSR strategies, policies and practices in Islamic Societies (IRI- Islamic Reporting Initiatives) supported by an ad-hoc interview held with an IRI’s Staff member. The conclusion of this research discusses the perspective of Islamic view in sustainability reporting by incorporating the concept of Tawhid which provides a holistic guidance based on Islamic beliefs, values and concepts (Aman, 2016) and, in specific, the main differences between western and Islamic Corporate Sustainability Reporting perspective. The finding of the paper is to be useful to integrate and develop sustainable strategies for Islamic companies.

description: The comparison of financial results between different cultural and religious systems is still an open academic debate. There is no consensus among scholars on the existence and magnitude of financial performance differences for companies acting under diverse cultural and religious background.
 The aim of this paper is to compare the performance of European listed firms applying Shariah principles and those who do not act according to such guidelines. To serve such purpose we have built a sample of companies operating with Shariah-based principles of management and compared the latter with a control comprising companies that do not adopt Shariah parameters over the period 2005–2017.
 Results suggest that the Shariah-compliant sample performs better than the conventional one. In particular, during the recent recession, Shariah-compliant companies obtained better periodical stock market returns and even in the event of negative returns, losses posted by these companies were lower than those of conventional companies. Moreover, Shariah-compliant sample presents a lower risk-profile than conventional one.

description: Gulacapsus novoguinensis Schuh Figure 21 Gulacapsus novoguinensis Schuh, 1984: 227, figs. 744, 746 (n. sp., diag., descr., DV, figs. headpronotum). DIAGNOSIS: Recognized by characters of generic diagnosis, narrow body form, small size, unicolorous cuneus, weakly swollen posterior margin of pronotum, and partial transverse fascia limited mostly to anterior of clavus. DESCRIPTION: See Schuh (1984). HOSTS: Unknown; collected in light traps. DISTRIBUTION: New Guinea. DISCUSSION: This species is one of the smallest species of Gulacapsus and the most similar to Australian species G. australiensis in shape and size. Both have the posterior lateral margins of the hemelytra nearly parallel sided with a weak medial constriction and shorter cuneus than the other species; however, the completely dark profemur and the partial transverse fascia in G. novoguinensis clearly separate the two.

Development and perspectives of ethical finance in Iran

description: — Iran has a rich and old tradition of ethical finance and economics. Well before the Islamic Revolution, institutes and initiatives were active in encouraging an inclusive vision of economy. Although re-elaborated under a different light, these concepts survived in the current Constitution, which defines economy using a “social” approach (art.43). Under this light, the legality of capitalism and that of the use of private investment are one of the pillars of economy itself (art.44) only if subordinated to religiously inspired ethical principles of justice and equity and in a way that makes of them a mere complement to State or to the corporative actors. Religious guidance is therefore immanent even in the very own definition of economy as a mean, and not as an end, to get social purposes like, inter alia, welfare, elimination of poverty  and abolition of deprivation of means of self-sustainment. State-driven economics was nevertheless a prominent concept in original Iranian constitutional thought. Starting from the Nineties, financial and economic reforms have been leading the system from a corporatist vision that characterised the first fifteen years of existence of the Islamic Republic to a more actual social market, putting in discussion and somewhat re-inventing the relationship between the public and the private.

description: Linear scaling methods, or O(N) methods, have computational and memory requirements which scale linearly with the number of atoms in the system, N, in contrast to standard approaches which scale with the cube of the number of atoms. These methods, which rely on the short-ranged nature of electronic structure, will allow accurate, ab initio simulations of systems of unprecedented size. The theory behind the locality of electronic structure is described and related to physical properties of systems to be modelled, along with a survey of recent developments in real-space methods which are important for efficient use of high performance computers. The linear scaling methods proposed to date can be divided into seven different areas, and the applicability, efficiency and advantages of the methods proposed in these areas is then discussed. The applications of linear scaling methods, as well as the implementations available as computer programs, are considered. Finally, the prospects for and the challenges facing linear scaling methods are discussed.

description: Motivated by the holographic principle, it has been suggested that the dark energy density may be inversely proportional to the area $A$ of the event horizon of the universe. However, such a model would have a causality problem. In this work, we consider the entropy-corrected version of the holographic dark energy model in the non-flat FRW universe and we propose to replace the future event horizon area with the inverse of the Ricci scalar curvature. We obtain the equation of state (EoS) parameter $ω_Λ$, the deceleration parameter $q$ and $Ω_D'$ in the presence of interaction between Dark Energy (DE) and Dark Matter (DM). Moreover, we reconstruct the potential and the dynamics of the tachyon, K-essence, dilaton and quintessence scalar field models according to the evolutionary behavior of the interacting entropy-corrected holographic dark energy model.
