description: We hypothesized that clinically sized (1-5 mm thick),compact cardiac constructs containing physiologically high density of viable cells (~108 cells/cm3) can be engineered in vitro by using biomimetic culture systems capable of providing oxygen transport and electrical stimulation, designed to mimic those in native heart. This hypothesis was tested by culturing rat heart cells on polymer scaffolds, either with perfusion of culture medium (physiologic interstitial velocity, supplementation of perfluorocarbons), or with electrical stimulation (continuous application of biphasic pulses, 2 ms, 5 V, 1 Hz). Tissue constructs cultured without perfusion or electrical stimulation served as controls. Medium perfusion and addition of perfluorocarbons resulted in compact, thick constructs containing physiologic density of viable, electromechanically coupled cells, in contrast to control constructs which had only a ~100 mm thick peripheral region with functionally connected cells. Electrical stimulation of cultured constructs resulted in markedly improved contractile properties, increased amounts of cardiac proteins, and remarkably well developed ultrastructure (similar to that of native heart) as compared to non-stimulated controls. We discuss here the state of the art of cardiac tissue engineering, in light of the biomimetic approach that reproduces in vitro some of the conditions present during normal tissue development.

description: Genes carry the instructions for making proteins that are found in a cell as a specific sequence of nucleotides that are found in DNA molecules. But, the regions of these genes that code for proteins may occupy only a small region of the sequence. Identifying the coding regions play a vital role in understanding these genes. In this paper we propose a unsupervised Fuzzy Multiple Attractor Cellular Automata (FMCA) based pattern classifier to identify the coding region of a DNA sequence. We propose a distinct K-Means algorithm for designing FMACA classifier which is simple, efficient and produces more accurate classifier than that has previously been obtained for a range of different sequence lengths. Experimental results confirm the scalability of the proposed Unsupervised FCA based classifier to handle large volume of datasets irrespective of the number of classes, tuples and attributes. Good classification accuracy has been established.

title: Untersuchung der Sauerstoffdynamik in Metalloxiden an den Beispielen von CeO2 und Mo8V2W0,5Ox - Eine operando Raman-Studie
Creators: name: Ohlig, Dominik

description: Im Rahmen dieser Arbeit wurde der Einfluss der Sauerstoffdynamik in Abhängigkeit des Ortes auf das Aktivitäts-/Selektivitätsverhalten für die selektive Oxidation von Acrolein zu Acrylsäure an Mo8V2W0,5Ox mittels operando Raman-Spektroskopie untersucht. Weiterhin wurde unter Verwendung von operando Raman-Spektroskopie eine vergleichende Studie der selektiven Oxidation von Acrolein und Methacrolein an Mo8V2W0,5Ox durchgeführt. Zu diesem Zweck wurde eine operando Raman-Zelle für die Untersuchung von Mischoxidkatalysatoren unter prozessrelevanten Bedingungen im Labormaßstab entwickelt und in einen bestehenden operando Raman-Aufbau mit Raman-Mikroskop und XYZ-Probentisch integriert. Neben der Optimierung des Versuchsaufbaus wurde eine Methode zur Identifizierung redoxsensitiver Raman-Signale erarbeitet. Die Validierung des Versuchsaufbaus und der Methodik erfolgte am Modellsystem CeO2 durch Untersuchung der kontrollierten Knallgasreaktion. Im Anschluss daran folgte die Untersuchung des technisch relevanten Zielsystems Mo8V2W0,5Ox. Die Ergebnisse zeigen einen direkten Zusammenhang zwischen dem Reduktionsgrad des Mischoxidkatalysators und der integralen Selektivität der selektiven Oxidation von alpha,beta-ungesättigten Aldehyden zur korrespondierenden Säure. Im stationären Zustand wird entlang des Katalysatorbetts eine Zunahme des Reduktionsgrads in Flussrichtung beobachtet. Der Verlauf des Gradienten ist abhängig vom Sauerstoffgehalt der gasförmigen Reaktionsmischung und wirkt sich auf die integrale Selektivität zu alpha,beta-ungesättigten Säure aus. Die verlangsamte Oxidation von Methacrolein zu Methacrylsäure am Mischoxid kann auf die verstärkte Bildung von Coke-Depositen zurückgeführt werden.

description: We present heat capacity measurements on a series of superconducting Cu$_x$TiSe$_2$ single crystals with different Cu content down to 600 mK and up to 1 T performed by ac microcalorimetry. The samples cover a large portion of the phase diagram from an underdoped to a slightly overdoped region with an increasing superconducting critical temperature and the charge density wave (CDW) order gradually suppressed. The electronic heat capacity as a function of normalized temperature $T/T_c$ shows no difference regardless of the concentration of copper, i.e., regardless of how much the CDW order is developed in the samples. The data analysis reveals consistently a single s-wave gap with an intermediate coupling strength $2Δ/k_BT_c$ = 3.7 for all samples.

description: The authors present a comparative analysis of employment determination in four transition economies as they moved from central planning to a market economy in the early 1990s. They use firm-level panel data sets from the Czech Republic, Hungary, Poland, and Slovakia to estimate dynamic employment equations for the period immediately before and after the start of transition. For the most part, firms appear to have been quick to adjust employment to wage levels, and there is little evidence of labor hoarding. There were important cross-country variations in the determinants of employment during the reform process, however. Hungarian and Polish firms started the transition already substantially reformed, and became even more responsive to market signals as transition proceeded. In contrast, firms in the Czech and Slovak Republics started in the completely unresponsive mode characteristic of central planning, but rapidly caught up with their counterparts in Hungary and Poland.

description: We use two large samples of firms to assess the effects of business environment constraints, competition, export orientation, and ownership on firm performance. We deal with omitted variables, errors in variables, and endogeneity, and find that few business constraints affect performance. Replicating the analysis with Doing Business and Heritage Foundation indicators of the business environment yields similar results. In fact, country fixed effects, reflecting time-invariant differences in the business environment as well as other factors such as health care and education, matter more for firm performance than differences in the business environment across firms within countries.

description: In this paper, we evaluate what we have learned to date about the effects of privatization from the experiences during the last fifteen to twenty years in the postcommunist (transition) economies and, where relevant, China. We distinguish separately the impact of privatization on efficiency, profitability, revenues, and other indicators and distinguish between studies on the basis of their econometric methodology in order to focus attention on more credible results. The effect of privatization is mostly positive in Central Europe, but quantitatively smaller than that to foreign owners and greater in the later than earlier transition period. In the Commonwealth of Independent States, privatization to foreign owners yields a positive or insignificant effect while privatization to domestic owners generates a negative or insignificant effect. The available papers on China find diverse results, with the effect of nonstate ownership on total factor productivity being mostly positive but sometimes insignificant or negative.

description: The primary goal of this study was to characterize the response of chondrocyte-seeded agarose constructs to varying concentrations of several key nutrients in a chondrogenic medium, within the overall context of optimizing the key nutrients and the placement of nutrient channels for successful growth of cartilage tissue constructs large enough to be clinically relevant in the treatment of osteoarthritis (OA). To this end, chondrocyte-agarose constructs (phi4x2.34 mm, 30x106 cells/mL) were subjected to varying supplementation levels of insulin (0× to 30× relative to standard supplementation), transferrin (0x to 30x), selenous acid (0x to 10x), ascorbate (0x to 30x), and glucose (0x to 3x). The quality of resulting engineered tissue constructs was evaluated by their compressive modulus (E-Y), tensile modulus (E+Y), hydraulic permeability (k), and content of sulfated glycosaminoglycans (sGAG) and collagen (COL); DNA content was also quantified. Three control groups from two separate castings of constructs (1x concentrations of all medium constituents) were used. After 42 days of culture, values in each of these controls were, respectively, E-Y=518 plus or minus 78, 401 plus or minus 113, 236 plus or minus 67 kPa; E+Y=1420 plus or minus 430, 1140 plus or minus 490, 1240 plus or minus 280 kPa; k=2.3 plus or minus 0.8x10-3, 5.4 plus or minus 7.0x10-3, 3.3 plus or minus 1.3x10-3 mm4/N times s; sGAG=7.8 plus or minus 0.3, 6.3 plus or minus 0.4, 4.1 plus or minus 0.5%/ww; COL=1.3 plus or minus 0.2, 1.1 plus or minus 0.3, 1.4 plus or minus 0.4%/ww; and DNA=11.5 plus or minus 2.2, 12.1 plus or minus 0.6, 5.2 plus or minus 2.8 μg/disk. The presence of insulin and ascorbate was essential, but their concentrations may drop as low as 0.3x without detrimental effects on any of the measured properties; excessive supplementation of ascorbate (up to 30x) was detrimental to E-Y, and 30x insulin was detrimental to both E+Y and E-Y. The presence of glucose was similarly essential, and matrix elaboration was significantly dependent on its concentration (p less than 10-6), with loss of functional properties, composition, and cellularity observed at less than or equal to 0.3x; excessive glucose supplementation (up to 3x) showed no detrimental effects. In contrast, transferrin and selenous acid had no influence on matrix elaboration. These findings suggest that adequate distributions of insulin, ascorbate, and glucose, but not necessarily of transferrin and selenous acid, must be ensured within large engineered cartilage constructs to produce a viable substitute for joint tissue lost due to OA.

description: We discuss the two-dimensional isotropic antiferromagnet in the framework of gauge invariance. Gauge invariance is one of the most subtle useful concepts in theoretical physics, since it allows one to describe the time evolution of complex physical systesm in arbitrary sequences of reference frames. All theories of the fundamental interactions rely on gauge invariance. In Dirac's approach, the two-dimensional isotropic antiferromagnet is subject to second class constraints, which are independent of the Hamiltonian symmetries and can be used to eliminate certain canonical variables from the theory. We have used the symplectic embedding formalism developed by a few of us to make the system under study gauge-invariant. After carrying out the embedding and Dirac analysis, we systematically show how second class constraints can generate hidden symmetries. We obtain the invariant second-order Lagrangian and the gauge-invariant model Hamiltonian. Finally, for a particular choice of factor ordering, we derive the functional Schrödinger equations for the original Hamiltonian and for the first class Hamiltonian and show them to be identical, which justifies our choice of factor ordering.

description: In native bone, cells experience fluctuating shear forces that are induced by pulsatile interstitial flow associated with habitual loading. We hypothesized that the formation of engineered bone can be augmented by replicating such physiologic stimuli to osteogenic cells cultured in porous scaffolds using bioreactors with medium perfusion. To test this hypothesis, we investigated the effect of fluid flow regime on in vitro bone-like tissue development by human adipose stem cells (hASC) cultivated on porous three-dimensional silk fibroin scaffolds. To this end, we varied the sequential relative durations of steady flow (SF) and pulsatile flow (PF) of culture medium applied over a period of 5 weeks, and evaluated their effect on early stages of bone formation. Porous silk fibroin scaffolds (400-600 μm pore size) were seeded with hASC (30×106 cells/mL) and cultured in osteogenic medium under four distinct fluid flow regimes: (1) PF for 5 weeks; (2) SF for 1 week, PF for 4 weeks; (3) SF for 2 weeks, PF for 3 weeks; (4) SF for 5 weeks. The PF was applied in 12 h intervals, with the interstitial velocity fluctuating between 400 and 1200 μm/s at a 0.5 Hz frequency for 2 h, followed by 10 h of SF. In all groups, SF was applied at 400 μm/s. The best osteogenic outcomes were achieved for the sequence of 2 weeks of SF and 3 weeks of PF, as evidenced by gene expression (including the PGE2 mechanotransduction marker), construct compositions, histomorphologies, and biomechanical properties. We thus propose that osteogenesis in hASC and the subsequent early stage bone development involve a mechanism, which detects and responds to the level and duration of hydrodynamic shear forces.

We derive two-term asymptotics for eigenvalues in the limit when the distance between the hypersurfaces tends to zero. The asymptotics are uniform and local in the sense that the coefficients depend only on the extremal points where the ratio of the area of the Neumann boundary to the Dirichlet one is locally the biggest.

description: Economic development implies that the efficiency of firms in developing countries starts approaching that of firms from advanced economies. Various development policies have been pursued to achieve this convergence. We test for this convergence in two economies that represent alternative models of implementing market-oriented development policies: the Czech Republic and Russia. Using 1992–2000 panel data on virtually all medium and large industrial firms in each country and accounting for endogeneity of ownership, we find that foreign ownership markedly improved the efficiency of firms, whereas domestic private ownership did not; domestic firms are not catching up to the (world) efficiency standard given by foreign-owned firms. This is due in part to a slower growth of efficiency in domestic firms over time. However, foreigners' acquisitions of more efficient domestic firms are also contributing to the gap. Domestic firms closer to the frontier are not more likely to catch up than firms farther from the frontier, although foreign firms do exhibit this behavior. The distance of Russian firms to the efficiency frontier is much larger than that of Czech firms. Nevertheless, after nearly a decade of reforms, neither model of development has resulted in convergence of domestic firms to the world standard.

description: Group lifting structures are introduced to provide an algebraic framework for studying lifting factorizations of two-channel perfect reconstruction finite-impulse-response (FIR) filter banks. The lifting factorizations generated by a group lifting structure are characterized by Abelian groups of lower and upper triangular lifting matrices, an Abelian group of unimodular gain scaling matrices, and a set of base filter banks. Examples of group lifting structures are given for linear phase lifting factorizations of the two nontrivial classes of two-channel linear phase FIR filter banks, the whole- and half-sample symmetric classes, including both the reversible and irreversible cases. This covers the lifting specifications for whole-sample symmetric filter banks in Parts 1 and 2 of the ISO/IEC JPEG 2000 still image coding standard. The theory is used to address the uniqueness of lifting factorizations. With no constraints on the lifting process, it is shown that lifting factorizations are highly nonunique. When certain hypotheses developed in the paper are satisfied, however, lifting factorizations generated by a group lifting structure are shown to be unique. A companion paper applies the uniqueness results proven in this paper to the linear phase group lifting structures for whole- and half-sample symmetric filter banks.

description: Recent high-resolution observations from the Solar Dynamics Observatory (SDO) have reawakened interest in the old and fascinating phenomenon of solar tornado-like prominences. This class of prominences was first introduced by Pettit (1932), who studied them over many years. Observations of tornado prominences similar to the ones seen by SDO had already been documented by Secchi (1877) in his famous "Le Soleil". High resolution and high cadence multiwavelength data obtained by SDO reveal that the tornado-like appearance of these prominences is mainly an illusion due to projection effects. We discuss two different cases where prominences on the limb might appear to have a tornado-like behavior. One case of apparent vortical motions in prominence spines and barbs arises from the (mostly) 2D counterstreaming plasma motion along the prominence spine and barbs together with oscillations along individual threads. The other case of apparent rotational motion is observed in prominence cavities and results from the 3D plasma motion along the writhed magnetic fields inside and along the prominence cavity as seen projected on the limb. Thus, the "tornado" impression results either from counterstreaming and oscillations or from the projection on the plane of the sky of plasma motion along magnetic field lines, rather than from a true vortical motion around an (apparent) vertical or horizontal axis. We discuss the link between tornado-like prominences, filament barbs, and photospheric vortices at their base.

description: The rising incidence of adipose-related disorders such as obesity has prompted increased interest in the in vitro development of functional human soft tissues to study the disease and treatment options. Further, soft tissues maintained in vitro with a capacity to resemble in vivo tissues in structure and metabolic function would help gain insight into mechanisms involved in adipose tissue development. In the current study, the metabolic potential of adipose/endothelial cocultures on three-dimensional silk fibroin scaffolds was studied. Endothelial contributions to adipose lipogenesis and lipolysis were the focus of the study. Triglyceride accumulation, adipogenic gene transcript expression, and basal lipolysis measurements demonstrated the ability of this coculture system to retain metabolic levels obtained in adipocyte monocultures. Additionally, basal lipolysis was stimulated in mono- and coculture systems to a similar extent at 1.6- and 1.9-fold over controls, respectively. The ability to maintain adipose functions in these cocultures represents a step forward in the development of a tissue-engineered adipose tissue system exhibiting both endothelial lumens and metabolic functions.

description: We previously showed that the sequential, but not simultaneous, culture of endothelial cells (ECs), fibroblasts (FBs), and cardiomyocytes (CMs) resulted in elongated, beating cardiac organoids. We hypothesized that the expression of Cx43 and contractile function are mediated by vascular endothelial growth factor (VEGF) released by nonmyocytes during the preculture period. Cardiac organoids (200 μm diameter) were cultivated in microchannels to enable rapid screening. Three experimental groups were formed: (i) Simultaneous Preculture (ECs+FBs for 48 h, followed by CMs), (ii) Sequential Preculture (ECs for 24 h, FBs for 24 h, followed by CMs), and (iii) Simultaneous Triculture (ECs+FBs+CMs). Controls included CMs only, FBs only, and ECs only groups, and preculture with ECs only or FBs only. The highest VEGF levels were found in the Preculture groups [Simultaneous Preculture, 8.9 plus or minus 2.7 ng/(mL times h−1); Sequential Preculture, 16.6 plus or minus 3.4 ng/(mL times h−1)], as compared with Simultaneous Triculture where VEGF was not detectable, as shown by enzyme-linked immunosorbent assay. Analytical flow cytometry showed that VEGFR2 was expressed by ECs (86% plus or minus 2 VEGFR2+), FBs (44% plus or minus 1 VEGFR2+), and CMs (49% plus or minus 2 VEGFR2+), showing that all three cell types were capable of responding to changes in VEGF. Addition of anti-VEGF neutralizing IgG (0.4 μg/mL) to Simultaneous Preculture resulted in 3-fold decrease in Cx43 mRNA and 1.5-fold decrease in Cx43 protein, while Simultaneous Triculture supplemented with VEGF ligand (30 ng/mL) had a threefold increase in Cx43 mRNA and a twofold increase in Cx43 protein. Addition of a small molecule inhibitor of the VEGFR2 receptor (19.4 nM) to Sequential Preculture caused a 1.4-fold decrease in Cx43 mRNA and a 4.1-fold decrease in Cx43 protein. Cx43 was localized within CMs, and not within FBs or ECs. Enriched CM organoids and Sequential Preculture organoids grown in the presence of VEGFR2 inhibitor displayed low levels of Cx43 and poor functional properties. Taken together, these results suggest that endogenous VEGF-VEGFR2 signaling enhanced Cx43 expression and cardiac function in engineered cardiac organoids.

description: We analyze the homothety types of associative bilinear forms that can occur on a Hopf algebra or on a local Frobenius \(k\)-algebra \(R\) with residue field \(k\). If \(R\) is symmetric, then there exists a unique form on \(R\) up to homothety iff \(R\) is commutative. If \(R\) is Frobenius, then we introduce a norm based on the Nakayama automorphism of \(R\). We show that if two forms on \(R\) are homothetic, then the norm of the unit separating them is central, and we conjecture the converse. We show that if the dimension of \(R\) is even, then the determinant of a form on \(R\), taken in \(\dot k/\dot k^2\), is an invariant for \(R\). \textit{Key words}: bilinear form, Frobenius algebra, homothety, Hopf algebra, isometry, local algebra, Nakayama automorphism, Ore extension, symmetric algebra

description: We investigate the use of compressive sampling for networked feedback control systems. The method proposed serves to compress the control vectors which are transmitted through rate-limited channels without much deterioration of control performance. The control vectors are obtained by an L1-L2 optimization, which can be solved very efficiently by FISTA (Fast Iterative Shrinkage-Thresholding Algorithm). Simulation results show that the proposed sparsity-promoting control scheme gives a better control performance than a conventional energy-limiting L2-optimal control.

description: The theory of group lifting structures is applied to linear phase lifting factorizations for the two nontrivial classes of two-channel linear phase perfect reconstruction filter banks, the whole- and half-sample symmetric classes. Group lifting structures defined for the reversible and irreversible classes of whole- and half-sample symmetric filter banks are shown to satisfy the hypotheses of the uniqueness theorem for group lifting structures. It follows that linear phase group lifting factorizations of whole- and half-sample symmetric filter banks are therefore independent of the factorization methods used to construct them. These results cover the specification of whole-sample symmetric filter banks in the ISO/IEC JPEG 2000 image coding standard.

description: Introduction. This paper reports the outcomes from a literature review of the concept of data cultures as the first step in extending the body of knowledge relating to information culture in the information science domain and raising awareness of the need for further research. Method. A scoping literature review was conducted of English language peer reviewed publications indexed in SCOPUS as well as specialist information and computer science databases. Results. There is a rich and growing body of research concerned with the concept of data cultures, spread across a wide range of disciplines but without any evidence of a universally adopted shared definition or understanding. Information science expertise does not appear to be widely recognised as providing any essential insight into this problem space. Conclusion. The knowledge and understanding of information cultures gained from information science research does not seem to be being applied to data dominated environments. Expertise relating to information behaviour, digital literacies, information management, digital sustainability and preservation are unique and essential perspectives to understand issues relating to data cultures.

Holographic fluid from nonminimally coupled scalar-tensor theory of gravity

description: We establish the gravity/fluid correspondence in the nonminimally coupled scalar-tensor theory of gravity. Imposing Petrov-like boundary conditions over the gravitational field, we find that, for a certain class of background metrics, the boundary fluctuations obey the standard Navier-Stokes equation for an incompressible fluid without any external force term in the leading order approximation under the near horizon expansion. That is to say, the scalar field fluctuations does not contribute in the leading order approximation regardless of what kind of boundary condition we impose on it.

description: Cardiac tissue engineering will remain only a prospect unless large numbers of therapeutic cells can be provided, either from small samples of cardiac cells or from stem cell sources. In contrast to most adult cells, cardiomyocytes are terminally differentiated and cannot be expanded in culture. We explored the feasibility of enabling the in vitro expansion of primary neonatal rat cardiomyocytes by lentivector-mediated cell immortalization, and then reverting the phenotype of the expanded cells back to the cardiomyocyte state. Primary rat cardiomyocytes were transduced with simian virus 40 large T antigen (TAg), or with Bmi-1 followed by the human telomerase reverse transcriptase (hTERT) gene; the cells were expanded; and the transduced genes were removed by adenoviral vector expressing Cre recombinase. The TAg gene was more efficient in cell transduction than the Bmi-1/hTERT gene, based on the rate of cell proliferation. Immortalized cells exhibited the morphological features of dedifferentiation (increased vimentin expression, and reduced expression of troponin I and Nkx2.5) along with the continued expression of cardiac markers (α-actin, connexin-43, and calcium transients). After the immortalization was reversed, cells returned to their differentiated state. This strategy for controlled expansion of primary cardiomyocytes by gene transfer has potential for providing large amounts of a patient's own cardiomyocytes for cell therapy, and the cardiomyocytes derived by this method could be a useful cellular model by which to study cardiogenesis.

description: Sensor technology is evolving rapidly, offering new opportunities for environmental data collection. Yet, despite the large number of sensors now available, there is a lack of logging platforms that can be used to operate these sensors in situ. To address this shortfall, River Restoration Intelligence and Verification (RRIV) has developed an environmental data logger that meets the needs of the environmental sensing community. This platform has several advantages that reduce the time, effort, and technical know-how required to deploy environmental sensors. An extensive low-power mode is available, and hardware such as a real-time clock with an independent power source is incorporated. A driver system has been developed that allows users to incorporate sensors into the platform with minimal effort. RRIV loggers also include a command line interface that allows user to add or remove sensors, calibrate sensors, or configure deployments without the need for C/C++ programming, something that is not possible with out-of-the-box microcontrollers such as Arduino and ST Nucleo products. The technology incorporated into RRIV and how it is applied and deployed in the field is described. This includes a description of power consumption. Protocols and descriptions of case construction are also included. RRIV loggers configured to monitor carbon dioxide and methane are used to demonstrate how this platform is used in the field.

description: It has been found that noise plays a key role to improve signal transmission in a one-way chain of bistable systems [Zhang et al., Phys. Rev. E 58, 2952 (1998)]. We here show that the signal transmission can be sharply improved without the aid of noise, if the one-way chain with a single source node is changed with two source nodes becoming a Y-shaped one-way chain. We further reveal that the enhanced signal transmission in the Y-shaped one-way chain is regulated by coupling strength, and that it is robust to noise perturbation and input signal irregularity. We finally analyze the mechanism of the enhanced signal transmission by the Y-shaped structure.

description: Lao PDR (Laos), with its significant hydropower potential, imports electricity during the dry season (November to April) despite having increased its generation capacity in the last decade. In this policy brief, an energy system expansion model is used to evaluate two scenarios to understand the dynamics around energy self-sufficiency and the impact of reduced dependence on electricity imports from its Association of Southeast Asian Nations (ASEAN) neighbours. The Business-as-Usual scenario projects prolonged electricity imports with significant financial costs, while the No-Import scenario highlights energy deficits in early years, underscoring challenges in halting imports abruptly. The findings emphasise the need for accelerated renewable energy deployment, particularly solar and wind, along with the planned hydropower infrastructure investments. Strategic energy planning, diversification of the energy mix, and grid enhancements are critical for improving Laos’ energy security and reducing reliance on imports while aligning with the United Nations’ Sustainable Development Goals (SDGs).

description: Lao PDR faces a complex energy challenge balancing coal-fired power exports with its climate goals. Currently Laos operates three coal-fired power plants; however, it also aims to reduce greenhouse gas emissions by 60% by 2030 and achieve net-zero by 2050. This analysis, utilising an energy systems optimisation model, explores a future with no new coal investments, revealing potential for significant changes. By 2028, solar PV and wind power could substitute coal in meeting export commitments. The analysis reveals that a no-coal future could reduce CO2 emissions, save on infrastructure costs, and maintain export commitments while enhancing energy security. Strategic investments in renewable energy are crucial for this transition.
