description: The frequency constitutes a key state variable of electrical power grids. However, as the frequency is subject to several sources of fluctuations, ranging from renewable volatility to demand fluctuations and dispatch, it is strongly dynamic. Yet, the statistical and stochastic properties of the frequency fluctuation dynamics are far from fully understood. Here, we analyse properties of power grid frequency trajectories recorded from different synchronous regions. We highlight the non-Gaussian and still approximately Markovian nature of the frequency statistics. Further, we find that the frequency displays significant fluctuations exactly at the time intervals of regulation and trading, confirming the need of having a regulatory and market design that respects the technical and dynamical constraints in future highly renewable power grids. Finally, employing a recently proposed synthetic model for the frequency dynamics, we combine our statistical and stochastic analysis and analyse in how far dynamically modelled frequency properties match the ones of real trajectories.

description: We investigate the Josephson transport through a thin semiconductor barrier containing impurity centers with the on-site Hubbard interaction $u$ of an arbitrary sign and strength. We find that in the case of the repulsive interaction the Josephson current changes sign with the temperature increase if the energy of the impurity level $ε$ (measured from the Fermi energy of superconductors) falls in the interval $(-u,0)$. We predict strong temporal fluctuations of the current if only a few centers present within the junction. In the case of the attractive impurity potential ($u<0$) and at low temperatures, the model is reduced to the effective two level Hamiltonian allowing thus a simple description of the nonstationary Josephson effect in terms of pair tunneling processes.
Transformation Properties of External Radiation Fields, Energy-Loss Rates and Scattered Spectra, and a Model for Blazar Variability

Publisher: name: arXiv
Year: 2002

description: We treat transformation properties of external radiation fields in the proper frame of a plasma moving with constant speed. The specific spectral energy densities of external isotropic and accretion-disk radiation fields are derived in the comoving frame of relativistic outflows, such as those thought to be found near black-hole jet and gamma-ray burst sources. Nonthermal electrons and positrons Compton-scatter this radiation field, and high-energy protons and ions interact with this field through photomeson and photopair production. We revisit the problem of the Compton-scattered spectrum associated with an external accretion-disk radiation field, and clarify a past treatment by the authors. Simple expressions for energy-loss rates and Thomson-scattered spectra are given for ambient soft photon fields consisting either of a surrounding external isotropic monochromatic radiation field, or of an azimuthally symmetric, geometrically thin accretion-disk radiation field. A model for blazar emission is presented that displays a characteristic spectral and variability behavior due to the presence of a direct accretion-disk component. The disk component and distinct flaring behavior can be bright enough to be detected from flat spectrum radio quasars with {\it GLAST}. Spectral states of blazars are characterized by the relative importance of the accretion-disk and scattered radiation fields and, in the extended jet, by the accretion disk, inner jet, and cosmic microwave background radiation fields.

description: Using a multiphase transport model, we study the production of multistrange baryons from the hadronic matter formed in relativistic heavy ion collisions. The mechanism we introduce is the strangeness-exchange reactions between antikaons and hyperons. We find that these reactions contribute significantly to the production of multistrange baryons in heavy ion collisions at SPS energies, which has been found to be appreciably enhanced. We have also made predictions for multistrange baryon production in heavy ion collisions at RHIC and found a similar enhancement.

Year: 1995
Subjects: Demand and Price Analysis

description: This study has been performed to find out the factors affecting demand for the fertilizers, urea, triple super phosphate and muriate of potash and also to estimate the relative contribution of the factors by using econometric models. Understanding the behavior of the variables are crucial as fertilizer crisis has become a regular phenomenon and also because fertilizer is so important to our agriculture. Cobb-Douglus type production function has been conceived for the analysis and estimation was done by ordinary least square in double log form. It is found that the price of urea do not play a significant role in determining its demand but prices of TSP and MOP are vital in their demand determinanation and these demands are price elastic. Non-price factors are important as demand factors, and fertilizer demand in all the three types has seasonal variation. Considering the future direction, it is highly likely that urea has to be imported in near future at a higher international price compared to the existing domestic price.

description: In this work, we investigate if the learned encoder of the end-to-end convolutional time domain audio separation network (Conv-TasNet) is the key to its recent success, or if the encoder can just as well be replaced by a deterministic hand-crafted filterbank. Motivated by the resemblance of the trained encoder of Conv-TasNet to auditory filterbanks, we propose to employ a deterministic gammatone filterbank. In contrast to a common gammatone filterbank, our filters are restricted to 2 ms length to allow for low-latency processing. Inspired by the encoder learned by Conv-TasNet, in addition to the logarithmically spaced filters, the proposed filterbank holds multiple gammatone filters at the same center frequency with varying phase shifts. We show that replacing the learned encoder with our proposed multi-phase gammatone filterbank (MP-GTF) even leads to a scale-invariant source-to-noise ratio (SI-SNR) improvement of 0.7 dB. Furthermore, in contrast to using the learned encoder we show that the number of filters can be reduced from 512 to 128 without loss of performance.

description: Kine khowa ("purchased food") is an indigenous concept of wealth ranking which has been adapted byNon-Govemmental Organisations (NGOs) to target and evaluate Farming Systems Research (FSR) for small farmers in Bangladesh. This analysis of the Mennonite Central Committee's (MCC) FSR programme in southern Bangladesh suggests that kine khowa was useful for identifying target groups but less useful for evaluating the impact of FSR interventions since increases in household assets and income were not necessarily reflected in improved household food security.

Regularity conditions for spherically symmetric solutions of Einstein-nonlinear electrodynamics equations; revised and improved version

Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this report, the regularity conditions at the center for static spherically symmetric (SSS) solutions of the Einstein equations coupled to nonlinear electrodynamics (NLE) with Lagrangian $\mathcal{L}= \mathcal{L}(\mathcal{F})$, depending on the electromagnetic invariant $\mathcal{F}=F_{μν}\,F^{μν}/4$, are established. The traceless Ricci (TR) tensor eigenvalue $S$, the Weyl tensor eigenvalue $Ψ_2$ and the scalar curvature $R$ characterize the independent Riemman tensor invariants of SSS metrics. The necessary and sufficient regularity conditions for electric NLE SSS solutions require $\lim_{r\rightarrow 0}\{Ψ_2,S,R\}\rightarrow \{0,0,(0,4Λ+ 4\mathcal{L}(0))\}$, such that the metric function $Q(r)$ and the electric field $q_0F_{rt}=:\mathcal{E}$ behave as $\{Q,\dot Q,\ddot Q\}\rightarrow\{0,0,2\}$ and $\{\mathcal{E},\dot\mathcal{E},\ddot\mathcal{E}\}\rightarrow\{0,0,0\}$, as $r\rightarrow 0$. The general linear integral representation of the electric NLE SSS metric in terms of an arbitrary electric field $\mathcal{E}$, together with $\{Ψ_2,S,R\}$, is explicitly given. Moreover, beside the regular or singular behavior at the center, these solutions may exhibit different asymptotic behavior at spatial infinity such as the Reissner--Nordtröm (Maxwell) asymptotic, or present the dS--AdS or other kind of asymptotic.

description: Solar conversion of water into chemical energy carriers offers a sustainable alternative to fossil fuels. Inspired by natural processes, dye-sensitised photoelectrochemical cells provide a platform for H2 generation from water. Fuel-forming photocathodes are currently limited by the small range of wide-bandgap p-type semiconductors available. The majority of previous reports have employed NiO, which displays low performance with immobilised dyes and catalysts, requiring exploration of other metal oxides. In this thesis, CuCrO2 is presented as an alternative p-type semiconductor for dye-sensitised H2 production. Synthesis and characterisation of CuCrO2 using a sol-gel method is described. First, co-immobilisation of a phosphonated diketopyrrolopyrrole dye with a Ni-bis(diphosphine) catalyst on CuCrO2 is presented as a strategy for producing a functional photocathode capable of generating H2 (Chapter 2). Photocurrent analysis and product detection revealed a high turnover number for the catalyst, outperforming an analogous NiO photoelectrode. The study serves to demonstrate the benefits of adopting delafossite structures for dye-sensitised systems. The versatility of sol-gel synthesised CuCrO2 was highlighted through immobilisation of ZnSe nanorods (NRs) (Chapter 3). Ligand-stripped ZnSe-NRs were deposited on CuCrO2 to produce the first reported ZnSe-sensitised photocathode capable of photoelectrochemical proton reduction under solar irradiation. Hydrothermal synthesis of CuCrO2 nanoparticles enabled the development of nanostructured inverse opal electrodes (IO-CuCrO2) using a bottom-up templating method (Chapter 4). These electrodes were explored as a scaffold for solar H2 production together with a molecular Ni catalyst and two different organic dyes based on perylene monoimide and diketopyrrolopyrrole chromophores. Improved activity over the mesoporous CuCrO2 films was associated with the novel morphology of the p-SC and the integration of a more suitable dye for hole injection. Photoelectrochemical analysis and a discussion of the influence of molecular components in these highly proficient electrodes provides a basis for future development of dye-sensitised CuCrO2-based photocathodes.

description: The collective Raman cooling of a trapped two-component Fermi gas is analyzed. We develop the quantum master equation that describes the collisions and the laser cooling, in the festina lente regime, where the heating due to photon reabsorption can be neglected. The numerical results based on Monte Carlo simulations show, that three-dimensional temperatures of the order of 0.008 T_F can be achieved. We analyze the heating related to the background losses, and conclude that our laser-cooling scheme can maintain the temperature of the gas without significant additional losses. Finally we derive an analytic expression for the temperature of a trapped Fermi gas heated by background collisions, that agrees very well with the data obtained from the numerical simulation.

description: Metastatic cancer cells detect the direction of lymphatic flow by self-communication: they secrete and detect a chemical which, due to the flow, returns to the cell surface anisotropically. The secretion rate is low, meaning detection noise may play an important role, but the sensory precision of this mechanism has not been explored. Here we derive the precision of flow sensing for two ubiquitous detection methods: absorption vs.\ reversible binding to surface receptors. We find that binding is more precise due to the fact that absorption distorts the signal that the cell aims to detect. Comparing to experiments, our results suggest that the cancer cells operate remarkably close to the physical detection limit. Our prediction that cells should bind the chemical reversibly, not absorb it, is supported by endocytosis data for this ligand-receptor pair.

description: Recent literature on pastoralism tends to either portray it as a largely maladaptive practice on the brink of collapse, or as a highly adaptive set of practices that enable resilience in the face of change and uncertainty. This dissertation seeks to find a solution to this impasse and contribute to debates about pastoral communities through a historical and ethnographic study of the Ilng’wesi Maasai. Ilng’wesi today self-identify as pastoralists. They once formed part of the Ilaikipiak alliance in the mid-nineteenth century, before being defeated by another Maasai section and fleeing to the forests of Mt Kenya, where they spent half a century dependent on foraging, ivory trading and livestock herding labour. Today, they live in more or less the same location, where they practice pastoralism, as well as engaging in paid labour and sand harvesting. Their history offers an excellent opportunity to study the extent to which pastoralism’s role as a socio-moral practice and a focal point of identity endures through material, political and economic change. In giving an account of their history, the dissertation attempts to balance the conventional focus in pastoralist studies on material and technical practices and livelihoods with a close examination of emic processes of meaning-making, moral understanding and identity formation. In particular, it explores how Ilng’wesi themselves link their identities with livelihood practices, and how a close identification with pastoralism – often expressed in both moral and ethnic terms – has shaped pastoral livelihoods and is likely to shape them in the future. It does so through the concept of ‘moral identity’, which builds on and adapts John Lonsdale’s account of moral ethnicity. The dissertation uses historical and ethnographic insights to substantiate this concept in relation to Iln’gwesi livelihoods and identity. This is carried out through four empirical chapters: one on Ilng’wesi livelihood transitions between the nineteenth and twentieth centuries, and possible explanations for these transitions; one on the impact of colonial rule on Ilng’wesi moral identity; one on use of the vernacular of moral identity in evaluating political candidates during the 2017 general election; and one on the changing cattle rustling practices of Ilng’wesi youth.

description: This research examined the appropriateness of a 2-parameter model for crop insurance premium ratemaking. Besides conventional way of calculating crop insurance premium using normal curve theory, this study uses empirical crop yield's distribution to measure downside risk in approximating crop insurance premium. Statistical means for all selected crops by country in Ontario with respect to premium calculated under normal yield distribution assumption (NPREM) and premium calculated using empirical yield distribution (EPREM) are presented. With respect to NPREM and EPREM, a significant statistical difference between mean premiums by crops at various coverage levels are found. This study argue that this difference is mainly attributed to the differences in downside risk. This issue is particularly important, because rejecting a null hypothesis that NPREM and EPREM are equivalent, suggest that approximation of the true (i.e., empirical) distribution by a normal distribution may bias insurance premiums. However the key finding is that in determining crop insurance premium, the downside-risk measured relative to a normal yield distribution function does not necessarily violate research which determines crop insurance premium using empirical crop yield's distribution function.

description: To assess the potential impact of international developments on public attitudes in Germany, we regularly conduct survey experiments. These experiments are embedded in the representative Survey „Menschen in Deutschland International“ („People in Germany: International) which is conducted bimonthly since November 2022. One important issue are effects of the ongoing military conflict in the Middle East on political attitudes and protest behavior among people living in Germany. At present increases of the prevalence of anti-Semitic prejudice as well as an increase of violence against jewish people and jewish institution are a heavily debated social and political Problem in Germany.

In an initial survey experiment conducted in May 2023 we examined the impact of reports on the use of armed force against Palestinian civilians in the West Bank on antisemitic and anti-Israel protest behavior in Germany. In this experiment, we systematically varied whether the violence described in the scenarios was perpetrated by the Israeli military or by Jewish settlers. We found that violence committed by the Israeli military significantly increased acceptance of antisemitic protest behavior. However, this effect was almost exclusively observed among individuals who already exhibited traditional antisemitic prejudices. No effects were observed for identical violence carried out by Jewish settlers.

In a follow-up study conducted in September 2024, we replicated and expanded this experiment. The new study aimed to examine 1) whether the effects observed in May 2023 were still present in 2024, following Hamas' attack on Israel, 2) whether these findings were region-specific or applicable to attacks by the Israeli military in the West Bank, Gaza Strip, and southern Lebanon, and 3) whether the moderating effect of traditional antisemitic prejudices could also be observed for pre-existing Israel-related antisemitic attitudes.

description: We describe the zero-temperature phase diagram of a model of a two-dimensional square-lattice array of neutral atoms, excited into Rydberg states and interacting via strong van der Waals interactions. Using the density-matrix renormalization group algorithm, we map out the phase diagram and obtain a rich variety of phases featuring complex density wave orderings, upon varying lattice spacing and laser detuning. While some of these phases result from the classical optimization of the van der Waals energy, we also find intrinsically quantum-ordered phases stabilized by quantum fluctuations. These phases are surrounded by novel quantum phase transitions, which we analyze by finite-size scaling numerics and Landau theories. Our work highlights Rydberg quantum simulators in higher dimensions as promising platforms to realize exotic many-body phenomena.

description: Theoretically, the phase transition between the confined and deconfined phases of quarks can have a remarkable effect on the spin properties of millisecond pulsars and on the spin distribution of the population of x-ray neutron stars in low-mass binaries. In the latter class of stars, the effect has already been observed---a strong clustering in the population in a narrow band of spins. The observed clustering cannot presently be uniquely assigned to the phase transition as cause. However, there is another possible signal---not so far observed---in millisecond pulsars that we also discuss. It would have the same origin, and its discovery would tend to confirm the interpretation in terms of a phase transition in the stellar core and that the high density phase exists in the higer mass canonical neutron stars.

description: The paper explores the potential of Khao Dawk Mali expansion in Northern Thailand as well as presents estimation of demand for variable inputs and choice of rice varieties as jointly determined by the profit-maximizing farmers. Results reveal that, Khao Dawk Mali provides economic advantage over glutinous varieties and can be conceived as a better alternative crop particularly in areas with inadequate irrigation and water control facilities. Consideration of the possibility of rice variety switching, that is, allowing the movement along a meta-production function, improved the elasticity estimates. A two-stage switching regression procedure which adjusts for selectivity bias is used to estimate the model. From the viewpoint of both cost-effectiveness and distributional consideration, price policies for raising rice yields and farm income in Chiang Mai province should focus on rice prices and tractor power prices.

description: In this study, changes in agricultural output (in value terms) resulting from changes in cropping pattern alone have been worked out for three different regions and Punjab State as a whole. This has been worked out by deducting changes brought about as a result of changes in yield, price and total cropped area from the total changes in agricultural output. Our analysis indicates that in absolute terms the total returns due to changes in cropping pattern of various crops increased by Rs. 94.03 crores over a period of 28 years i. e. 1965-70 through 1988-93. Within various regions, south western region alone contributed 60.85 percent of the total additional returns obtained at the state level (94.03 crores), while central region and sub-mountainous regions contributed 32.76 and 6.39 percent respectively of the total additional returns.

description: We study the time evolution of the entangled kaon system by considering the Liouville - von Neumann equation with an additional term which allows for decoherence. We choose as generators of decoherence the projectors to the 2-particle eigenstates of the Hamiltonian. Then we compare this model with the data of the CPLEAR experiment and find in this way an upper bound on the strength $λ$ of the decoherence. We also relate $λ$ to an effective decoherence parameter $ζ$ considered previously in literature. Finally we discuss our model in the light of different measures of entanglement, i.e. the von Neumann entropy $S$, the entanglement of formation $E$ and the concurrence $C$, and we relate the decoherence parameter $ζ$ to the loss of entanglement: $1 - E$.

description: This article interrogates the role of the Nigerian Diaspora in contributing financial and intellectual remittances for national development. It does so because conventional diaspora studies have focused on how various diaspora populations adapt to the social, economic, and political realms in the countries of settlement even as they seek to maintain their own traditions and cultures. Recent developments indicate Diasporas have played prominent roles in the political, social, and economic development of their countries of origin. As a result, it becomes crucial to integrate the role of the Diaspora in contributing not just financial but also intellectual remittances to enhance national development. This is because intellectual remittances are critical for institution building and addressing leadership deficit which will in turn channel financial remittances into proper national development agenda. Yet, this is too often neglected in the extant literature. Relying on the diaspora option theory and Hirschman’s exit, voice and loyalty theory, with data gleaned from a structured questionnaire survey, interviews, institutional reports, and other secondary sources, this article explores how diaspora communities serve as critical bridges that facilitate national development through financial and intellectual remittances. The study revealed that whereas financial remittance is important for addressing development gaps, it becomes more forceful when combined with other forms of remittances such as intellectual and social remittances. The motivation for this study was to understand the contributions of the diaspora population who in spite of their physical exit from home continue to make their voices heard and felt by contributing both knowledge and financial resources towards the growth and development of Nigeria. Nigeria faces scary challenges of national development, and the quest for socio-economic transformation led the government to devise an engagement strategy to draw from the experiences and expertise of her citizens living outside the country known as the diaspora population. Incidentally, this segment of the population living outside the shores of their home country is sometimes forced by dire socio-economic circumstances to migrate and settle in other climes where they not only contribute to the growth of their host country but make monetary and knowledge contributions to families and communities back home. The study concludes that the diaspora contribution is crucial and pivotal to national development but it is not a magic wand or elixir that can fix all the challenges affecting the country.
Revisiting patterns and processes of forest cover change in the tropics: a case study from southeast Mexico

description: Vast progress has been made in detecting rates of tropical deforestation, yet the relationship between visible patterns of forest change, multi-scalar human processes and the underlying drivers associated with them is poorly understood. Building on satellite imagery, a household livelihood survey and semi-structured interviews, this research scrutinised changes of forest cover from the mid-1990s to 2015 in a municipality located in southeastern Mexico and investigated the proximate causes and underlying drivers of change at the household and community levels. Emerging evidence indicated that, contrary to the persistent narrative of deforestation for the region, forest cover change is highly dynamic including periods of deforestation and forest recovery. Moreover, a close examination of 24 communities showed forest cover gained terrain, while the agricultural frontier retracted. Drawing on a comparison between the household survey and previous analyses, it could be inferred that forest resurgence was produced by the decrease in the farming area and the increase in the abandonment of farming activities by some communities. Associated with the adaptation of households was the development of formal and informal institutions at the community level in response to macro-global forces linked to the implementation of forest conservation strategies, environmental degradation, market liberalization and increased urbanization. Overall, this research adds not only to our understanding of the complexity of land-use and cover change in emerging globalized economies but also exemplifies the spatial and temporal heterogeneity of tropical forest systems, which challenges partial models of deforestation and policies designed to reduce it. The research may be focused on a narrow region of the globe, nevertheless, the insights and recommendation provided may be useful to further forest conservation schemes in other tropical regions.

description: Recent changes in farm policy have renewed interest in using marketing strategies based on futures and options markets to enhance the income of crop producers. This article reviews the literature surrounding the dominant academic theory of the behavior of futures and options markets, the efficient market hypothesis. The following conclusion is reached: While individuals can beat the market, few can consistently do so. Those few who consistently earn trading returns have superior access to information or superior analytical ability. This conclusion is consistent with Grossman and Stiglitz's model of market performance when information is costly. One implication is that if any "expert" offers advice on taking a futures or options position, first ask for a statement of their past trading record. To follow on, we recommend that reporting of actual performance be required by the Commodity Futures Trading Commission. A second implication is the importance of cost of production relative to marketing in determining the long term survival of crop producers. With very few exceptions, the crop producers who survive will be those with the lowest cost of production since efforts to improve revenue through better marketing will have limited success. Thus, a good marketing program starts with a good program for managing and controlling cost of production. However, all is not lost for the individual crop producer when it comes to enhancing income from prudent marketing. Simple strategies exist which can enhance average return. These strategies use the market as a source of information, rather than as a trading medium. An example is to base storage decisions on whether the current basis exceeds the cost of storage, and to time storage decisions based on when a producer harvests the crop relative to the national harvest of the crop. Stated somewhat differently, an effective marketing program begins with first learning and practicing effective cash marketing.

description: Cure models are a special type of survival analysis model where it is assumed that there are a proportion of subjects who will never experience the event and thus the survival curve will eventually reach a plateau. In population-based cancer studies, cure is said to occur when the mortality (hazard) rate in the diseased group of individuals returns to the same level as that expected in the general population. The cure fraction is of interest to patients and a useful measure to monitor trends and differences in survival of curable disease. I will describe the strsmix and strsnmix commands, which t the two main types of cure fraction model, namely, the mixture and nonmixture cure fraction models. These models allow incorporation of the expected background mortality rate and thus enable the modeling of relative survival when cure is a possibility. I give an example to illustrate the commands.
