description: Score of Ingoma (1998, rev. 2000) for orchestra: "Prelude," "Lullaby - Thula, Babana," "Dance - Uqongqot'hwane" and "Postlude".
 Ingoma is an orchestral work based on two Xhosa traditional songs. Apart from the brief introduction and coda, the work consists of two sections, respectively based on a well-known lullaby, "Thula, Babana", and the even better-known "Uqongqot'hwane". As in their traditional settings, the melodies are repeated a number of times, with gradual variation and accumulation of accompanying textures. In the case of "Uqongqot’hwane", these textures are derived from the motifs heard on the brass in the introduction. These motifs reappear in the coda, after the climactic combination of the two main melodies.
 The work was commissioned by the Hugo Lambrechts Youth Orchestra. The "Lullaby" and "Dance" were intended for youth orchestra, while the "Prelude" and "Postlude", which may be omitted, are suitable for more advanced performers. Ingoma has also been arranged for flute quartet, recorder quartet, string quartet, viola quartet and string orchestra.

description: Few topics have a larger or more rapidly growing literature than monetary policy. The literature has wide diversity, ranging from highly abstract analyses of optimal money growth to the commentary ground out daily or weekly by central bank watchers in many countries. 1 In between are such issues as the choice of rules over discretion, the strategies and tactics of monetary action, the advantages of activism and, recently, the positive analysis of policymakers' decisions.

description: Οικοτουρισμός είναι ο τουρισμός που αναπτύσσεται σε οικολογικά αξιόλογες και επί το πλείστον περιοχές θεσμοθετημένης περιβαλλοντικής προστασίας (περιοχές Nartura). Τα τελευταία χρόνια εξελίσσεται σε μία από τις πιο δημοφιλείς μορφές τουρισμού. Προβάλλει τη φύση ως κύριο πόλο έλξης για τους επισκέπτες. Η εναλλακτική μορφή τουρισμού παράγει την αίσθηση της ηθικής ευθύνης, του σεβασμού και της εκτίμησης ως προς το φυσικό περιβάλλον. η διπλωματική αυτή εργασία, αποτελεί μια ολοκληρωμένη προσέγγιση, που συνδυάζει την προστασία της φύσης, την ανάδειξη της προσφοράς της στην ζωή του ανθρώπου, αλλά και την συνεισφορά της στην αρχιτεκτονική. Υπό το πρίσμα αυτό, επιλέξαμε το σχεδιασμό μιας οργανωμένης υποδομής, στην περιοχή των Αγίων Αποστόλων στα Χανιά, όπου το έντονο ανάγλυφο και οι υψομετρικές αποτέλεσαν έμπνευση κατά τον αρχιτεκτονικό σχεδιασμό. Σε κάθε αρχιτεκτονική παρέμβαση λήφθηκε υπόψη η ακριβής μορφολογία του εδάφους της περιοχής, η ιδιαιτερότητα του άθικτου φυσικού τοπίου και η βιοκλιματική παράμετρος. Πιο συγκεκριμένα επιλέξαμε το σχεδιασμό διαμονής σε καταλύματα ήπιου χαρακτήρα και μικρής δυναμικότητας, όπου οι κατοικίες συγχωνεύονται πλήρως στο περιβάλλον, καθιστώντας την ύπαρξη τους ως μια φυσιολογική μορφή στο επικείμενο έδαφος. Επιπλέον, προκειμένου η οικοτουριστική προσφορά να μην περιορίζεται στην απλή παροχή καταλύματος, επιδιώξαμε την παροχή δυνατοτήτων πραγματοποίησης βιωματικών εμπειριών, σχεδιάζοντας ένα θεραπευτικό κέντρο, ένα χώρο υποδοχής, ένα χώρο εστίασης και ένα καφέ, τα οποία παράλληλα έχουν ημιδημόσια χρήση και από τον ντόπιο πληθυσμό. Επιπρόσθετα, στο πλαίσιο της βιωματικής εμπειρίας του τόπου, σχεδιάσαμε ένα δημόσιο κεντρικό μονοπάτι με χώρους στάσης και σκίασης, το οποίο δίνει τη δυνατότητα στον επισκέπτη να αλληλεπιδράσει με τις βιοτικές συνιστώσες του συγκεκριμένου φυσικού περιβάλλον.

description: The title of this session asks an old question in a new form: Have institutional changes, in this case so-called globalization, reduced the effect of money on prices and other nominal variables? The simple answer is no, but a more complete answer would be, no for large countries like the United States but perhaps yes for small, open economies with free capital movements. I will give two principal reasons.

description: Using the reduced WZNW formulation we analyse the classical $W$ orbit content of the space of classical solutions of the $A_2$ Toda theory. We define the quantized Toda field as a periodic primary field of the $W$ algebra satisfying the quantized equations of motion. We show that this local operator can be constructed consistently only in a Hilbert space consisting of the representations corresponding to the minimal models of the $W$ algebra.

description: Eine tiefgreifende Recherche, die in die baugeschichtliche, soziale und politische Vergangenheit und Gegenwart des Wiener Marktwesens eintaucht, dabei die vergessenen Markthallen wiederentdeckt sowie rekonstruiert und städtische Veränderungen im Zusammenhang mit Lebensmitteln untersucht, führt zur fundierten Ausgangslage für den Entwurf einer Markthalle in Wien. Im ersten Teil werden die nutzungstypologischen Merkmale der Wiener Märkte ebenso beleuchtet wie die raumtypologischen Aspekte. Die Erkenntnisse aus der Literaturrecherche, die sowohl auf technische Bauführer der Stadt Wien aufbaut, als auch soziologische Überlegungen zur Stadt und dem damit verknüpften Marktwesen heranzieht, werden durch persönliche Gespräche mit Akteur*innen im Wiener Marktsystem, dem Marktamt sowie vor allem Marktverkäufer*innen und Marktbesucher*innen, verglichen und weiterentwickelt. Mit dem Entwurf der Markthalle soll an die europaweite Tradition von überdachten Märkten als urbane Übergangsräume mit Nahversorger-Qualitäten angeknüpft werden, ohne jedoch eine Transformation mit Rücksicht auf die gegenwärtigen Bedürfnisse zu vernachlässigen.
description: In-depth research that delves into the architectural, social and political past and present of the Viennese market system, rediscovering and reconstructing forgotten market halls and analysing urban changes in connection with food, leads to a well-founded starting point for the design of a market hall in Vienna. In the first part, the use-typological characteristics of the Viennese markets are examined as well as the spatial-typological aspects. The findings from the literature research, which is based on technical construction guides of the City of Vienna as well as sociological considerations on the city and the associated market system, are compared and further developed through personal interviews with actors in the Viennese market system, the market office and, above all, market vendors and market visitors. The design of the market hall is intended to build on the Europe-wide tradition of covered markets as urban transitional spaces with local supplier qualities, but without neglecting a transformation that takes current needs into account.

description: We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways to replenish nutrients that feed back into activity. A full theory is developed in terms of gradients in the active matter density and velocity, and applied to bacterial turbulence, topological defects and clustering. Currents with complex spatiotemporal patterns are obtained, which are tuneable through confinement. Our findings show that diversity in carpet architecture is essential to maintain biofunctionality.

The Progenitor Age and Mass of the Black-Hole-Formation Candidate N6946-BH1

description: The failed supernova N6946-BH1 likely formed a black hole (BH); we age-date the surrounding population and infer an age and initial mass for the progenitor of this BH formation candidate. First, we use archival Hubble Space Telescope imaging to extract broadband photometry of the resolved stellar populations surrounding this event. Using this photometry, we fit stellar evolution models to the color-magnitude diagrams to measure the recent star formation history (SFH). Modeling the photometry requires an accurate distance; therefore, we measure the tip of the red giant branch (TRGB) and infer a distance modulus of $29.47 \pm 0.079$ to NGC~6946, or a metric distance of $7.83 \pm 0.29$ Mpc. To estimate the stellar population's age, we convert the SFH and uncertainties into a probabilistic distribution for the progenitor's age. The region in the immediate vicinity of N6946-BH1 exhibits the youngest and most vigorous star formation for several hundred pc. This suggests that the progenitor is not a runaway star. From these measurements, we infer an age for the BH progenitor of $10.6^{+14.5}_{-5.9}$ Myr. Assuming that the progenitor evolved effectively as a single star, this corresponds to an initial mass of $17.9^{+29.9}_{-7.6}$ $M_{\odot}$. Previous spectral energy distribution (SED) modeling of the progenitor suggests a mass of $\sim$27 $M_{\odot}$. Formally, the SED-derived mass falls within our narrowest 68\% confidence interval; however, $91\%$ of the probability distribtuion function we measure lies below that mass, putting some tension between the age and the direct-imaging results.

The main body of the work consists of an extended invocation in the form of a polychoral motet, based on an anonymous Latin text, and ending with a plea for peace. This is preceded by a briefer introductory section, based on passages from the Old Testament, in which the horrors of violence and oppression are described. This section features several extra-musical effects (whispering, hissing, finger- and tongue-clicks, foot-stamping and indeterminate clusters), many of which form part of the South African choral tradition.

A comparison with the SU(3) case is made and finite-volume effects are then investigated. We find that for a large range of momenta the SU(2) and SU(3) propagators are remarkably alike. In the low-momentum region we compare with recent results obtained in DSE studies on a 4-torus.

description: The discovery of superconductivity in the two-leg ladder compound BaFe$_2$S$_3$ has established the 123-type iron chalcogenides as a novel and interesting subgroup of the iron-based superconductors family. However, in this 123 series, BaFe$_2$Se$_3$ is an exceptional member, with a magnetic order and crystalline structure different from all others. Recently, an exciting experiment reported the emergence of superconductivity in BaFe$_2$Se$_3$ at high pressure [J.-J. Ying, et al., Phys. Rev. B 95, 241109 (R) (2017)]. In this publication, we report a first principles study of BaFe$_2$Se$_3$. Our analysis unveils a variety of qualitative differences between BaFe$_2$S$_3$ and BaFe$_2$Se$_3$, including in the latter an unexpected chain of transitions with increasing pressure. First, by gradually reducing the tilting angle of iron ladders, the crystalline structure smoothly transforms from Pnma to Cmcm at ~6 GPa. Second, the system becomes metallic at 10.4 GPa. Third, its unique ambient pressure Block antiferromagnetic ground state is replaced by the more common CX antiferromagnetic order at ~12 GPa, the same magnetic state of the 123-S ladder. This transition is found at a pressure very similar to the experimental superconducting transition. Finally, all magnetic moments vanish at 30 GPa. This reported theoretical diagram of the complete phase evolution is important because of the technical challenges to capture many physical properties in high-pressure experiments. The information obtained in our calculations suggest different characteristics for superconductivity in BaFe$_2$Se$_3$ and BaFe$_2$S$_3$: in 123-S pairing occurs when magnetic moments vanish, while in 123-Se the transition region from Block- to CX-type magnetism appears to catalyze superconductivity. Finally, an additional superconducting dome above ~30 GPa is expected to occur.

description: The origin of the phenomenological deterministic laws that approximately govern the quasiclassical domain of familiar experience is considered in the context of the quantum mechanics of closed systems such as the universe as a whole. We investigate the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e. such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones. We discuss these requirements generally but study them specifically for coarse grainings of the type that follows a distinguished subset of a complete set of variables while ignoring the rest. More coarse graining is needed to achieve decoherence than would be suggested by naive arguments based on the uncertainty principle. Even coarser graining is required in the distinguished variables for them to have the necessary inertia to approach classical predictability in the presence of the noise consisting of the fluctuations that typical mechanisms of decoherence produce. We describe the derivation of phenomenological equations of motion explicitly for a particular class of models. Probabilities of the correlations in time that define equations of motion are explicitly considered. Fully non-linear cases are studied. Methods are exhibited for finding the form of the phenomenological equations of motion even when these are only distantly related to those of the fundamental action. The demonstration of the connection between quantum-mechanical causality and causalty in classical phenomenological equations of motion is generalized. The connections among decoherence, noise, dissipation, and the amount of coarse graining necessary to achieve classical predictability are investigated quantitatively.

description: The personal computer and the development of websites permit everyone to have rapid access to enormous quantities of data. If it were ever true that policy analysis in developed countries was hindered by availability of timely information, that restriction has now all but disappeared. Data in developed countries become available to all interested parties everywhere almost as soon as they are put out. The organizers of the Bank of Japan's eighth international conference ask us to consider an important question: Has the quality of information increased commensurately? Do we now know substantially more about what is happening in the world or in our own countries. Or, has the increase in information lagged far behind the increase in data which central bankers and financial markets receive?

description: This paper is concerned with efficiently coloring sparse graphs in the distributed setting with as few colors as possible. According to the celebrated Four Color Theorem, planar graphs can be colored with at most 4 colors, and the proof gives a (sequential) quadratic algorithm finding such a coloring. A natural problem is to improve this complexity in the distributed setting. Using the fact that planar graphs contain linearly many vertices of degree at most 6, Goldberg, Plotkin, and Shannon obtained a deterministic distributed algorithm coloring $n$-vertex planar graphs with 7 colors in $O(\log n)$ rounds. Here, we show how to color planar graphs with 6 colors in $\mbox{polylog}(n)$ rounds. Our algorithm indeed works more generally in the list-coloring setting and for sparse graphs (for such graphs we improve by at least one the number of colors resulting from an efficient algorithm of Barenboim and Elkin, at the expense of a slightly worst complexity). Our bounds on the number of colors turn out to be quite sharp in general. Among other results, we show that no distributed algorithm can color every $n$-vertex planar graph with 4 colors in $o(n)$ rounds.

Monetary Policy Analysis

subject: FOS: Economics and business

description: The past several years have seen very rapid development in the area of monetary policy analysis.1 A welcome aspect is the convergence of approaches used by academic and central-bank economists. For example, examination of a notable NBER conference volume2 and/or a special issue of the Journal of Monetary Economics (Vol. 43, July 1999) suggests that it would be difficult, if not impossible, to identify the author of almost any article or comment as belonging to one group or the other. A major stimulus to this convergence, I believe, was John Taylor’s exposition of the now-familiar “Taylor Rule,”3 which encouraged academics to focus on policy rules expressed in terms of interest-rate instruments (thereby conforming to actual central bank practices) and encouraged central bankers to think of policy in a more rule-like fashion.
Quantum back-reaction problems

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The macroscopic behavior of many physical systems can be approximately described by classical quantities. However, quantum theory demands the existence of omnipresent quantum fluctuations on top of this classical background -- which, albeit small, should have some impact onto its dynamics. The correct treatment of this quantum back-reaction is one of the main problems in quantum gravity and related to fundamental questions such as the initial (big bang) singularity or the cosmological constant. By means of the qualitative analogy between gravity and fluid dynamics, we try to shed some light onto these problems and show some of the difficulties associated with the calculation of the quantum back-reaction starting from the classical (macroscopic) equation of motion.

We also discuss about the validity of perturbation expansion in the symmetry breaking sector.

Improving effective foot care education for inner city patient’s living with diabetes: a quality improvement project
Creators: name: March, Samantha J
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of Project: Diabetic foot ulcers and lower extremity complications secondary to diabetes have been known to have multiple negative effects on patient care and healthcare costs. The purpose of this study was to enhance patient care through improving provider awareness on the importance of effective diabetic foot care education and see an increase in the amount of patient education being provided as evidenced by documentation. Methodology: This was a quality improvement (QI) project. An educational flyer on proper diabetic foot care and an in-service with internal medicine providers on the importance of providing and documenting foot care education was implemented at the study site and took effect on February 14th, 2023. Retrospective and prospective electronic records of diabetic patients seen in the out-patient internal medicine clinic were reviewed and analyzed to compare documentation rates pre- and post-implementation. Results: There were 16 internal medicine physicians involved in this QI project which was implemented over the span of three weeks. Although statistical significance was not attained, there was an 11% increase in the number of charts containing diabetic foot care education as evidenced by documentation following the intervention. Implications for Practice: The findings from this project serve as the foundation for incorporating safe and effective foot care education among diabetic patients seen in the internal medicine clinic. These findings can help facilitate and implement mandatory foot care education within the internal medicine clinic.

description: Discovering disease pathways, which can be defined as sets of proteins associated with a given disease, is an important problem that has the potential to provide clinically actionable insights for disease diagnosis, prognosis, and treatment. Computational methods aid the discovery by relying on protein-protein interaction (PPI) networks. They start with a few known disease-associated proteins and aim to find the rest of the pathway by exploring the PPI network around the known disease proteins. However, the success of such methods has been limited, and failure cases have not been well understood. Here we study the PPI network structure of 519 disease pathways. We find that 90% of pathways do not correspond to single well-connected components in the PPI network. Instead, proteins associated with a single disease tend to form many separate connected components/regions in the network. We then evaluate state-of-the-art disease pathway discovery methods and show that their performance is especially poor on diseases with disconnected pathways. Thus, we conclude that network connectivity structure alone may not be sufficient for disease pathway discovery. However, we show that higher-order network structures, such as small subgraphs of the pathway, provide a promising direction for the development of new methods.

description: In polycrystalline materials, grain boundaries are sites of enhanced atomic motion, but the complexity of the atomic structures within a grain boundary network makes it difficult to link the structure and atomic dynamics. Here we use a machine learning technique to establish a connection between local structure and dynamics of these materials. Following previous work on bulk glassy materials, we define a purely structural quantity, softness, that captures the propensity of an atom to rearrange. This approach correctly identifies crystalline regions, stacking faults, and twin boundaries as having low likelihood of atomic rearrangements, while finding a large variability within high-energy grain boundaries. As has been found in glasses [9,19,26], the probability that atoms of a given softness will rearrange is nearly Arrhenius. This indicates a well-defined energy barrier as well as a well-defined prefactor for the Arrhenius form for atoms of a given softness. The decrease in the prefactor for low-softness atoms indicates that variations in entropy exhibit a dominant influence on the atomic dynamics in grain boundaries.

description: Homer Jones' most important contributions have been to the practice of monetary policy. The research work that he directed at the Federal Reserve Bank of St. Louis and the positions he took and encouraged others to take contributed to the remarkable change that has occurred in the conduct of monetary policy during the past few years. Jones and his colleagues at St. Louis played a major role in shifting monetary policy from exclusive concern with short-term interest rates toward control of the stock of 'money.* If in the future, we are able to look back on a permanent shift from concern for interest rates to control of money by the Federal Reserve, the contributions of Jones, Darryl Francis and their colleagues will, I believe, be recognized widely. Dominating most internal discussions of monetary policy is the view that central banks must control market rates of interest. Central bankers9 concern about market interest rates is itself a consequence of the real bills doctrine that dominated thinking about monetary policy at the Federal Reserve during most of its history. The main idea emphasized by proponents of the real bills doctrine is that monetary policy should be conducted to provide credit in response to the 'needs of trade.9 In practice, the central banker monitored the movement of interest rates an member bank borrowing. If market interest rates rose and the rise was accompanied by an increase in loans eligible for discount at the central bank - real bills - a central bank operating according to the doctrine permitted borrowing to increase. The stocks of money and bank credit rose in periods of economic expansion and declined in recessions.
The quantum-classical crossover of a field mode

description: We explore the quantum-classical crossover in the behaviour of a quantum field mode. The quantum behaviour of a two-state system - a qubit - coupled to the field is used as a probe. Collapse and revival of the qubit inversion form the signature for quantum behaviour of the field and continuous Rabi oscillations form the signature for classical behaviour of the field. We demonstrate both limits in a single model for the full coupled system, for states with the same average field strength, and so for qubits with the same Rabi frequency.

description: Climate change has posed a threat to what has been the status quo for people, plants, and animals in Homer, Alaska. Through desktop research and field tests, this project developed land use recommendations using the United States Fish and Wildlife’s Resist-Accept-Direct (RAD) Framework that can be implemented on private and public plots in Homer, AK to achieve desired environmental resilience based on projected changes in climatic variables and ecological baselines. We assessed the extent of climate-induced changes in plant life cycles and developed management strategies within the RAD framework. Our methodology included town hall events and surveys to encourage public engagement and community-based planning, a citizen science initiative for continued data collection, and remote sensing combined with statistical analysis to correlate phenology with climate variables. We created a community-informed recommendations “menu” for management strategies for local plant species. Deliverables include a climate report assessing Homer's climatic changes over 75 years, a white paper consolidating climate change effects and vulnerabilities in the South Central region of Alaska, and an adaptive ecosystem management plan detailing research findings and conservation strategies that can be implemented on both public and private lands.
Erratum to "The Homogeneous Coordinate Ring of a Toric Variety", along with the original paper

description: This submission consists of two papers: 1) an erratum that corrects an error in the proof of Proposition 4.3 in my paper "The Homogeneous Coordinate Ring of a Toric Variety", and 2) the original (unchanged) version of the paper, published in 1995. The original paper introduced the homogeneous coordinate ring of a toric variety (now called the total coordinate ring or Cox ring) and gave a quotient construction. The paper also studied sheaves on a toric variety, and in Section 4 described its automorphism group. The error in the proof of Proposition 4.3 resulted from the faulty assumption that a certain set of graded endomorphisms forms a ring; rather, it is a monoid under composition. The erratum notes this error and gives a correct proof of the proposition.

Monetary and Fiscal Theories of the Price Level: The Irreconcilable Differences

description: The fiscal theory of the price level (FTPL) has attracted much attention but disagreement remains concerning its defining characteristics. Some writers have emphasized implications regarding interest-rate pegging and determinacy of rational expectations solutions, whereas others have stressed its capacity to generate equilibria in which price-level trajectories mimic those of bonds and differ drastically from those of money supplies. We argue that the FTPL attained prominence precisely because it appeared to provide a theory whose implications differ greatly from conventional monetary analysis; accordingly we review monetarist writings to identify the primary distinctions. In addition, we review recent findings concerning learnability—and therefore plausibility—of competing rational expectations equilibria. These indicate that when FTPL and monetarist equilibria differ, the latter are more plausible in the vast majority of cases. Under Ricardian assumptions, necessary for clear distinctions, theoretical analysis indicates that fiscal and monetary coordination is not necessary for macroeconomic stability.

description: Charge transport is a revealing probe of the quantum properties of materials. Strong interactions can blur charge carriers resulting in a poorly understood "quantum soup". Here we study the conductivity of the Fermi-Hubbard model, a testing ground for strong interaction physics, in a clean quantum system - ultracold $^6$Li in a 2D optical lattice. We determine the charge diffusion constant in our system by measuring the relaxation of an imposed density modulation and modeling its decay hydrodynamically. The diffusion constant is converted to a resistivity, which exhibits a linear temperature dependence and exceeds the Mott-Ioffe-Regel limit, two characteristic signatures of a bad metal. The techniques we develop here may be applied to measurements of other transport quantities, including the optical conductivity and thermopower.
Kinetic Selection of Template Polymer with Complex Sequences

description: Emergence and maintenance of polymers with complex sequences is a major question in the study of origins of life. To answer this, we studied a model polymerization reaction, where polymers are synthesized by stepwise ligation from two types of monomers, catalyzed by a long polymer as a template. Direct stochastic simulation and dynamical systems analysis revealed that the most dominant polymer sequence in a population successively changes against the flow rate of monomer to the system. The slower the flow, the more is the complex sequence selected. We discuss the relevance of this kinetic selection of sequence by the non-equilibrium flow rate to the origin of complex polymers.

description: Hydrogen, an attractive energy carrier due to its high energy content per unit mass, offers multiple promising pathways towards significant global decarbonization efforts. While traditional hydrogen production relies on fossil fuels (gray hydrogen), using renewable electricity sources for electrolysis enables the production of green hydrogen, a crucial step towards a sustainable future. RMI and NITI Aayog project that India’s hydrogen demand will rise by about 23 million tons from 2020 to 2050, with 94% of that increase representing an opportunity for green hydrogen. The country’s current hydrogen production relies heavily on steam methane reforming (SMR), but the National Green Hydrogen Mission hopes to establish India as a global hub for green hydrogen production, use, and export. Incentivizing green hydrogen supply chain investment, replacing gray hydrogen in existing applications, and supporting pilot projects in sectors like steel manufacturing and long-haul transportation are key strategies. Green hydrogen offers potential solutions to India’s present grid reliability challenges through long-duration energy storage, captive power generation, and ammonia co-firing. Storing excess renewable energy as green hydrogen can address renewable variability across a wide array of time periods. India, commonly relying on pumped hydro storage (PHS) and battery-based storage, could benefit from green hydrogen’s geographical flexibility (compared to PHS), socio-economic benefits, and extended storage capacity and duration. Decarbonizing captive generation, by replacing coal assets with green hydrogen in captive fuel cells and hydrogen gas turbines, is another key application. Finally, ammonia co-firing in existing coal power plants, using green hydrogen-derived ammonia, offers a pathway to reducing carbon emissions. Adding green ammonia, a carbon-free fuel, to the combustion process can reduce emissions without requiring complete replacement of existing infrastructure. International examples, such as the long-standing Teesside hydrogen storage project in the UK and ongoing ammonia co-firing demonstrations in Japan, provide valuable insights and context for India’s energy transition.
Non-thermal leptogenesis and gravitino problem in inflaton decay

description: In the present work we discuss baryon asymmetry in the non-thermal leptogenesis scenario and gravitino cosmology for an unstable gravitino with inflaton decay. We take into account two production mechanisms for gravitino, namely thermal production and inflaton decay. We wish to show in plots the allowed parameter space so that the BBN constraint and the requirement for the right baryon asymmetry are satisfied at the same time. However our analysis shows that it is impossible to achieve both goals simultaneously.

Monetary and Fiscal Policy in Open, Interdependent Economies with Fixed Exchange Rates

description: Analysis of open economies has been restricted in several important ways. One is the assumption, common also in much of the macro-economic analysis of a closed economy, that total output is fixed and invariant. A second restriction arises from treatment of the representative country as a small unit in a large market. All prices are set in competitive world markets, and exchange rates adjust to equate domestic and foreign prices. Three, asset portfolios are restricted to money and real capital, the latter is generally fixed or grows at a steady rate. Bonds and real capital are perfect substitutes, as in the Metzler model (1951) or Mundell's several extensions of that model (1968).
