Studies on brain nuclear RNA polymerase and chromatin transcription
Creators: name: Singh, Vijendra Kumar
Publisher: name: University of British Columbia
Year: 2011

description: In order to elaborate the nature of the mechanisms controlling the transcription of genes in the cells of higher organisms, studies have been carried out on brain nuclear RNA polymerase and the transcription of brain chromatin. Foremost, suitable conditions were developed for the solubilization of RNA polymerase in high yields from purified nuclei of beef brain. The solubilized enzyme was partially purified by ammonium sulphate fractionation followed by DEAE-cellulose chromatography. By this procedure, two DNA-dependent RNA polymerase activities, designated as RNA polymerase I and RNA polymerase II, were resolved. These were partly characterized on the basis of their differing catalytic properties. RNA polymerase II exhibits a preferential requirement for Mn⁺⁺ as the divalent cation and heat-denatured DNA as the template, is markedly stimulated by 0.2 M KCl and selectively inhibited by the toxin, α-amanitin. On the other hand, polymerase I prefers Mg⁺⁺ as the divalent cation and native DNA as the template, is considerably inhibited by 0.2 M KC1 and is not affected by α -amanitin. The capacity of RNA synthesis in vitro by RNA polymerase isolated from brain nuclei was markedly enhanced by polyamines such as spermidine or spermine. Spermidine exerted a much more pronounced effect on polymerase II than on polymerase I. Evidence is presented suggesting that RNA polymerase II activity may be preferentially stimulated by spermidine. Yeast RNA inhibited the activity of polymerase II and spermidine counteracted this inhibition almost completely, indicating that spermidine may act by circumventing the product-inhibition. The product of the polymerase II reaction sedimented at around 18 S in a sucrose-density gradient and appeared to be a complex of the type Enzyme-DNA-RNA. The template activity of the isolated brain chromatin for brain nuclear RNA polymerase II and E. coli RNA polymerase was less than 25% than that of the pure calf thymus DNA. This greatly repressed template capacity of the chromatin was probably due to the acid-soluble chromosomal proteins. The brain polymerase II was 3-4 times more active with acid-treated chromatin than pure DNA as template whereas the E. coli enzyme was almost equally active with either of these two templates. The RNA synthesised on either native or acid-treated chromatin as template by brain polymerase II was somewhat smaller in size than the RNA made on pure DNA as template. It appears that the control of transcription of genes in mammalian cells could be mediated by the multiplicity of the transcriptive enzyme, RNA polymerase, and by the physiological state of the template as well.

description: The Geminga pulsar has long been one of the most intriguing MeV-GeV gamma-ray point sources. We examine the implications of the recent Milagro detection of extended, multi-TeV gamma-ray emission from Geminga, finding that this reveals the existence of an ancient, powerful cosmic-ray accelerator that can plausibly account for the multi-GeV positron excess that has evaded explanation. We explore a number of testable predictions for gamma-ray and electron/positron experiments (up to ~100 TeV) that can confirm the first "direct" detection of a cosmic-ray source.

description: The consistent description of the nuclear response at low and high momentum transfer requires a unified dynamical model, suitable to account for both short- and long-range correlation effects. We report the results of a study of the charged current weak response of symmetric nuclear matter, carried out using an effective interaction obtained from a realistic model of the nucleon-nucleon force within the formalism of correlated basis functions. Our approach allows for a clear identification of the kinematical regions in which different interaction effects dominate.
Non-classical correlations from dissociation time entanglement

description: We discuss a strongly entangled two-particle state of motion that emerges naturally from the double-pulse dissociation of a diatomic molecule. This state, which may be called dissociation-time entangled, permits the unambiguous demonstration of non-classical correlations by violating a Bell inequality based on switched single particle interferometry and only position measurements. We apply time-dependent scattering theory to determine the detrimental effect of dispersion. The proposed setup brings into reach the possibility of establishing non-classical correlations with respect to system properties that are truly macroscopically distinct.

Standing out from the crowd : a study of frankie magazine, niche branding, and alternative femininities
Creators: name: Hunt, RJL
Publisher: name: University Of Tasmania
Year: 2023

description: In the digital age, print media is said to be in decline. At the same time, the genre of women's magazines has been subject to escalating critique for its practices of production and representation. In this context, an Australian 'indie' niche magazine for young women has achieved remarkable success. Launched in 2004 by an independent publisher, frankie magazine now has circulation figures that outdo established glossy women's titles such as Cosmopolitan and Vogue Australia. The magazine has received multiple industry accolades, and in 2014 its publisher was sold for a reported $10 million figure. This thesis employs a combination of industry study and textual analysis in order to examine frankie magazine's success, which is notable when compared with other niche titles. The thesis is concerned in particular with the gendered dimensions of the magazine, given the focus in lifestyle magazine scholarship on gender as the central 'problem' of magazine texts. To this end, the thesis explores ways in which frankie magazine and its production are discursively constructed in opposition to mainstream women's magazines, and identifies potentially subversive gender manoeuvres‚ÄövÑvp (Schippers 2002) in the text. However, the analysis also highlights ways in which frankie and its production can be thought of as distinctly 'mainstream'. The thesis argues that frankie has been successful because it balances an appealing textual subversiveness with conventional production practices, thereby allowing it to both signify an 'alternative' identity and occupy a lucrative position within the mainstream market. This is significant because it suggests there is room for subversiveness within a genre that has typically been thought of as inherently conservative, and indicates that alternative representations of femininity can have mainstream appeal. At the same time, this thesis demonstrates continuities between frankie and the conventional women's magazine industry, both in terms of production practices and the pervasiveness of gendered representations in which white, middleclass femininities are most visible. This thesis contributes an analysis of a contemporary magazine and its production to the field of women's magazine studies, in which studies of the industry contexts and dynamics informing magazine texts have previously been underrepresented.

description: Today's forging die manufacturing process must be adapted to several evolutions in machining process generation: CAD/CAM models, CAM software solutions and High Speed Machining (HSM). In this context, the adequacy between die shape and HSM process is in the core of machining preparation and process planning approaches. This paper deals with an original approach of machining preparation integrating this adequacy in the main tasks carried out. In this approach, the design of the machining process is based on two levels of decomposition of the geometrical model of a given die with respect to HSM cutting conditions (cutting speed and feed rate) and technological constrains (tool selection, features accessibility). This decomposition assists machining assistant to generate an HSM process. The result of this decomposition is the identification of machining features.

description: IntroductionDomestic violence and abuse (DVA) is prevalent, harmful and more dangerous among diaspora communities because of the difficulty accessing DVA services, language and migration issues. Consequently, migrant/refugee women are common among primary care populations, but evidence for culturally competent DVA primary care practice is negligible. This pragmatic cluster randomised controlled trial aims to increase DVA identification and referral (primary outcomes) threefold and safety planning (secondary outcome) among diverse women attending intervention vs comparison primary care clinics. Additionally, the study plans to improve recording of DVA, ethnicity, and conduct process and economic evaluations.Methods and analysisRecruitment of ≤28 primary care clinics in Melbourne, Australia with high migrant/refugee communities. Eligible clinics need ≥1 South Asian general practitioner (GP) and one of two common software programmes to enable aggregated routine data extraction by GrHanite. Intervention staff undertake three DVA training sessions from a GP educator and bilingual DVA advocate/educator. Following training, clinic staff and DVA affected women 18+ will be supported for 12 months by the advocate/educator. Comparison clinics are trained in ethnicity and DVA data entry and offer routine DVA care. Data extraction of DV identification, safety planning and referral from routine GP data in both arms. Adjusted regression analysis by intention-to-treat by staff blinded to arm. Economic evaluation will estimate cost-effectiveness and cost–utility. Process evaluation interviews and analysis with primary care staff and women will be framed by Normalisation Process Theory to maximise understanding of sustainability. Harmony will be the first primary care trial to test a culturally competent model for the care of diverse women experiencing DVA.

description: The image of the distressed female most likely to linger in the memory is the image of the one who did not die: the survivor, or Final Girl.‚ÄövÑvp -Carol J. Clover. Men, Women and Chainsaws. They're all the same. Some stupid killer stalking some big-breasted girl, who can't act, who is always running up the stairs when she should be running out the front door. It's insulting.‚ÄövÑvp -Sidney Prescott. Scream (1996). This thesis aims to re-evaluate the changing role and function of the Final Girl in horror film since 1974. This exploration demands both an understanding of horror film as a genre and the historical conditions that have shaped feminist and film critics' responses to them. It also demands an understanding of the changing horror audience and the ways horror film responds to its own critics. Theory and film do not exist in a vacuum, theory comments on film, film comments on theory and film comments on itself. As the two quotations that open this chapter show there is an interconnectedness between them. The Carol Clover quotation demonstrates how films develop character types that become an integral part of the genre which in turn then becomes theorised as an essential element of the genre. The quotation from Scream (1996), and the Scream film in particular, demonstrate a film commenting on its own genre. Both film and theory influence the development of film: Clover's identification of the Final Girl has led to the increasing prominence of the female survivor, as well as the development of this character away from her predictable and well-worn beginnings.
The Destruction of Thin Stellar Disks Via Cosmologically Common Satellite Accretion Events

description: Most Galaxy-sized systems (M_host ~ 10^12 M_sun) in the LCDM cosmology are expected to have accreted at least one satellite with a total mass M_sat ~ 10^11 M_sun = 3M_disk in the past 8 Gyr. Analytic and numerical investigations suggest that this is the most precarious type of merger for the survival of thin galactic disks because more massive accretion events are relatively rare and less massive ones preserve thin disk components. We use high-resolution, dissipationless N-body simulations to study the response of an initially-thin, fully-formed Milky-Way type stellar disk to these cosmologically common events and show that the thin disk does not survive. Regardless of orbital configuration, the impacts transform the disks into structures that are roughly three times as thick and more than twice as kinematically hot as the observed dominant thin disk component of the Milky Way. We conclude that if the Galactic thin disk is a representative case, then the presence of a stabilizing gas component is the only recourse for explaining the preponderance of disk galaxies in an LCDM universe; otherwise, the disk of the Milky Way must be uncommonly cold and thin for its luminosity, perhaps as a consequence of an unusually quiescent accretion history.

Protein binding studies by diafiltration
Creators: name: Palmer, Cecily M.
Publisher: name: University of British Columbia
Year: 2011

description: A diafiltration technique was used to study drug-protein interactions. Fraction V human serum albumin and plasma and two drugs (phenylbutazone and bishydroxycoumarin) with a high affinity for these substances were used in this investigation. Preliminary experiments were carried out to check for release of foreign substances and for binding of drug to the Amicon diafiltration apparatus. A binding experiment, in the absence of drug, revealed release of a protein-like, ultraviolet absorbing substance from Fraction V human serum albumin. The most suitable method of purification for albumin was by diafiltration with Tris buffer. Binding curves for bishydroxycoumarin - human serum albumin, phenylbutazone - human serum albumin, and bishydroxycoumarin - plasma interactions were obtained. The r and r/Df [subscript omitted] values were calculated and binding parameters estimated by both graphical extrapolation and by a computer non-linear least squares fit analysis. Binding curves were not independent of human serum albumin concentration, but the cause of this effect was not fully resolved. Results showed the diafiltration technique can yield precise data, can be used over a wide macromolecule concentration range and produces a binding curve, from one experiment, over a wide range of molar binding ratios. Use of the Amicon diafiltration apparatus in desorption (washout) experiments and equilibrium or direct experiments was also investigated. Attempts were made to obtain binding data by centrifugation (ultrafiltration) and by a gel filtration technique (Sephadex G-25 batch method). These methods yielded unsatisfactory results which could not be compared with those obtained by diafiltration. This abstract represents the true contents of the thesis submitted.

Linear spectrum is estimated for mean temperatures versus frequency between 1420, 820 and 408 MHz. The spectral index of Monoceros loop is also obtained. The brightness temperatures and surface brightnesses of the loop are computed using data taken from radio-continuum surveys at the three frequencies. The spectral index of the loop is also obtained from $T-T$ plots between 1420 - 820, 1420 - 408 and 820 - 408 MHz. The obtained results confirm non-thermal origin of the Monoceros radio loop.

description: The forces between charged macromolecules, usually given in terms of osmotic pressure, are highly affected by the intervening ionic solution. While in most theoretical studies the solution is treated as a homogeneous structureless dielectric medium, recent experimental studies concluded that, for a bathing solution composed of two solvents (binary mixture), the osmotic pressure between charged macromolecules is affected by the binary solvent composition. By adding local solvent composition terms to the free energy, we obtain a general expression for the osmotic pressure, in planar geometry and within the mean-field framework. The added effect is due to the permeability inhomogeneity and nonelectrostatic short-range interactions between the ions and solvents (preferential solvation). This effect is mostly pronounced at small distances and leads to a reduction in the osmotic pressure for macromolecular separations of the order 1--2 nm. Furthermore, it leads to a depletion of one of the two solvents from the charged macromolecules (modeled as planar interfaces). Lastly, by comparing the theoretical results with experimental ones, an explanation based on preferential solvation is offered for recent experiments on the osmotic pressure of DNA solutions.

description: Today's High-Speed Machining (HSM) machine tool combines productivity and part quality. The difficulty inherent in HSM operations lies in understanding the impact of machine tool behaviour on machining time and part quality. Analysis of some of the relevant ISO standards (230-1998, 10791-1998) and a complementary protocol for better understanding HSM technology are presented in the first part of this paper. These ISO standards are devoted to the procedures implemented in order to study the behavior of machine tool. As these procedures do not integrate HSM technology, the need for HSM machine tool tests becomes critical to improving the trade-off between machining time and part quality. A new protocol for analysing the HSM technology impact during circular interpolation is presented in the second part of the paper. This protocol which allows evaluating kinematic machine tool behaviour during circular interpolation was designed from tests without machining. These tests are discussed and their results analysed in the paper. During the circular interpolation, axis capacities (such as acceleration or Jerk) related to certain setting parameters of the numerical control unit have a significant impact on the value of the feed rate. Consequently, a kinematic model for a circular-interpolated trajectory was developed on the basis of these parameters. Moreover, the link between part accuracy and kinematic machine tool behaviour was established. The kinematic model was ultimately validated on a bore machining simulation.

description: In this work, a quantum dot couples to two helical edge states of a 2D topological insulator through weak tunnelings is studied. We show that if the electron interactions on the edge states are repulsive, with Luttinger liquid parameter $ K < 1 $, the system flows to a stable two-channel fixed point at low temperatures. This is in contrast to the case of a quantum dot couples to two Luttinger liquid leads. In the latter case, a strong electron-electron repulsion is needed, with $ K<1/2 $, to reach the two-channel fixed point. This two-channel fixed point is described by a boundary Sine-Gordon Hamiltonian with a $K$ dependent boundary term. The impurity entropy at zero temperature is shown to be $ \ln\sqrt{2K} $. The impurity specific heat is $C \propto T^{\frac{2}{K}-2}$ when $ 2/3 < K < 1 $, and $ C \propto T$ when $ K<2/3$. We also show that the linear conductance across the two helical edges has non-trivial temperature dependence as a result of the renormalization group flow.

description: This thesis is an articulation of how I make sense of being a young Tasmanian Aboriginal woman through story, place and movement. The first part of the thesis consists of creative works that chart multiple approaches to the question How does movement create the conditions in which story and place bring each other into being?. The second part of the thesis is an exegesis of the creative works, which consists of two parts: the context of the creative works and the analysis of the creative works. The context traces the route my family and I walk from punnilerpanner country / Tarleton, the country that grew me up, to tebrakunna / Cape Portland, my ancestral country, as well as the multiple departures and returns that constitute the (ongoing) route. I outline the cultural practice of walking on country and examine how it relates to story and place. I also engage in dialogue with western philosophical and literary perspectives on the interrelatedness of place, narrative and movement. The analysis examines the responses that arise out of the creative process. This thesis, therefore, functions as both a story and a map: it is a map become story, and a story become map.
Blast performance of composite sandwich structures with hybrid laminate skins
Creators: name: Rolfe, Emily Louise
Publisher: name: Imperial College London
Year: 2019

description: This research project has investigated the performance of composite sandwich panels with hybrid skins against air and underwater blast loading. The loads are equivalent to those that could arise from sea mine detonation. Composite sandwich materials offer many benefits over conventional ship building materials. However, due to their variability and subsequent unpredictability, widespread use of composite sandwich panels in structural applications across the naval industry has been slow. The panel variability and interactions between the various constituent materials can, however, be utilised. Hybrid composite skins aimed to increase the blast resilience of composite sandwich panels by promoting energy absorbing damage mechanisms caused by the differing skin materials. Preliminary calculations and impact loading revealed the differences in panel performance that can be achieved by varying the hybrid skin layups. Placing glass-fibre as the outermost layer receiving the impact was shown to be beneficial. Additionally, it was advantageous to place carbon-fibre as the rearmost layer due to its high tensile strength and stiffness. These preliminary results were used to inform panel selection for full-scale blast testing. A number of full-scale air blast experiments were performed. Six types of composite sandwich panel were subjected to varying blast loads, benchmark conventional sandwich panels were tested where possible. The blast loads included large charges at large stand-off distances, small near-field charges as well as repeat blast loading. The experimental results revealed that hybrid composite panels with 50% glass-fibre and 50% carbon-fibre by volume achieve high blast resilience under the blast conditions tested. These 50:50 hybrids have the necessary strength and stiffness to prevent excessive skin or core damage whilst allowing an acceptable level of deflection. Under blast conditions, the presence of the two materials in the hybrid skin is the dominating factor. The layup of the hybrid skins has a minimal effect on overall performance. Instrumentation methods were extended compared to previous blast experiments. Spatial correlation between strain gauges mounted on the front skin and rear skin digital image correlation strain was achieved and polyvinylidene fluoride gauges were used in a large scale blast environment. The repeatability of the experimental setup and method was demonstrated. Lastly, one large scale underwater blast experiment was performed. Full-field panel response was recorded using digital image correlation. The results revealed the significant influence of water depth along with the severe deflection and damage sustained by the panel. Digital image correlation captured the underwater deflection profile of the panel from its initial position to the typically observed 'bath tub' shape for the first time. All experiments have demonstrated the significant blast resilience possessed by composite sandwich panels.

description: We analyzed simultaneous archival XMM-Newton and RXTE observations of the X-ray binary and black hole candidate Swift J1753.5-0127. In a previous analysis of the same data a soft thermal component was found in the X-ray spectrum, and the presence of an accretion disk extending close to the innermost stable circular orbit was proposed. This is in contrast with the standard picture in which the accretion disk is truncated at large radii in the low/hard state. We tested a number of spectral models and we found that several of them fit the observed spectra without the need of a soft disk-like component. This result implies that the classical paradigm of a truncated accretion disk in the low/hard state can not be ruled out by these data. We further discovered a broad iron emission line between 6 and 7 keV in these data. From fits to the line profile we found an inner disk radius that ranges between ~6-16 gravitational radii, which can be in fact much larger, up to ~250 gravitational radii, depending on the model used to fit the continuum and the line. We discuss the implications of these results in the context of a fully or partially truncated accretion disk.

On resonant and non-resonant origin of double-mode Cepheid pulsation

description: Double-mode Cepheid behaviour may arise either from non-resonant or resonant mode interaction. Inclusion of turbulent convection into pulsation codes by Kollath et al. (1998) led to stable double-mode F+1O Cepheid pulsation. However, our recent computations (Smolec & Moskalik 2008) indicate, that these models resulted from incorrect neglect of negative buoyancy effects. Once these effects are taken into account, only some resonant double-mode models could be found. These models do not solve the puzzle of double-mode phenomenon, as they are restricted to narrow parameter ranges. For majority of the observed double-mode Cepheids non-resonant mechanism has to be operational.

Structure and function of synovial joints, with particular reference to the mechanism of their lubrication
Creators: name: Piper, Michael Stafford
Publisher: name: University of British Columbia
Year: 2011

description: The structure and physiology of synovial joints has been studied for years. Recent advances in technology and investigative tools have enabled workers to greatly elucidate the nature of these remarkably functional joints. This thesis presents a review of the literature dealing with the morphology and physiology of diarthrodial joints. The embryological development and the gross structure of these joints is presented as is a discussion of the light and electron microscopic features of articular cartilage and synovial membrane. In addition, some of the features of synovial fluid are presented. The results of recent investigation into the biochemistry and metabolism of articular cartilage are discussed. As the main function of synovial joints is to provide painless, controlled motion, much interest has recently focused on the mechanism of lubrication in these joints. A review of the literature concerning the nature of joint lubrication is presented, and a theory of lubrication enhancement by electrical repulsive forces is proposed. This theory was developed from the results of a technique of synovianalysis conducted on a series of 61 samples of synovial fluid. The samples were collected from a series of hospital patients. One group of patients suffered from rheumatoid arthritis, while a second group was comprised of patients suffering from conditions not associated with rheumatoid arthritis. The samples were subjected to analysis using cation sensitive glass electrodes, and the concentrations of ionized sodium and potassium were measured. In addition, sodium and potassium concentrations were measured in the synovial fluid samples using a spectrophotometer. As a result of these investigations, it was found that the synovial fluid samples from patients with rheumatoid arthritis contained a significantly lower concentration of ionized sodium. It is concluded that the lower concentration of sodium ions in synovial fluid of rheumatoid arthritis may result in a diminution of electrical repulsive forces acting within synovial joints, and explain, in part, the cartilage attrition seen in this disease.

description: Nowadays high speed machining (HSM) machine tool combines productivity and part quality. So mould and die maker invested in HSM. Die and mould features are more and more complex shaped. Thus, it is difficult to choose the best machining strategy according to part shape. Geometrical analysis of machining features is not sufficient to make an optimal choice. Some research show that security, technical, functional and economical constrains must be taken into account to elaborate a machining strategy. During complex shape machining, production system limits induce feed rate decreases, thus loss of productivity, in some part areas. In this paper we propose to analyse these areas by estimating tool path quality. First we perform experiments on HSM machine tool to determine trajectory impact on machine tool behaviour. Then, we extract critical criteria and establish models of performance loss. Our work is focused on machine tool kinematical performance and numerical controller unit calculation capacity. We implement these models on Esprit CAM Software. During machining trajectory creation, critical part areas can be visualised and analysed. Parameters, such as, segment or arc lengths, nature of discontinuities encountered are used to analyse critical part areas. According to this visualisation, process development engineer should validate or modify the trajectory.

description: We study a porous medium equation, with nonlocal diffusion effects given by an inverse fractional Laplacian operator. We pose the problem in n-dimensional space for all t>0 with bounded and compactly supported initial data, and prove existence of a weak and bounded solution that propagates with finite speed, a property that is nor shared by other fractional diffusion models.

description: We use the deep ground-based optical photometry of the Lyman Break Galaxy (LBG) Survey to derive robust measurements of the faint-end slope (alpha) of the UV LF at redshifts 1.92000 spectroscopic redshifts and ~31000 LBGs in 31 spatially-independent fields over a total area of 3261 arcmin^2. These data allow us to select galaxies to 0.07L* and 0.10L* at z~2 and z~3, respectively. A maximum likelihood analysis indicates steep values of alpha(z=2)=-1.73+/-0.07 and alpha(z=3)=-1.73+/-0.13. This result is robust to luminosity dependent systematics in the Ly-alpha equivalent width and reddening distributions, is similar to the steep values advocated at z>4, and implies that ~93% of the unobscured UV luminosity density at z~2-3 arises from sub-L* galaxies. With a realistic luminosity dependent reddening distribution, faint to moderately luminous galaxies account for >70% and >25% of the bolometric luminosity density and present-day stellar mass density, respectively, when integrated over 1.92 contrasts with the shallower value inferred locally, suggesting that the evolution in the faint-end slope may be dictated simply by the availability of low mass halos capable of supporting star formation at z<2.

Non-Markovian melting: a novel procedure to generate initial liquid like phases for small molecules for use in computer simulation studies
Creators: name: McBride, Carl

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Computer simulations of liquid phases require an initial configuration from which to begin. The preparation of such an initial configuration or `snapshot' often involves the melting of a solid phase. This melting is usually undertaken by heating the system at low pressure, followed by a lengthy re-compression and cooling once the melt has formed. This note looks at a novel technique to produce a liquid phase from a perfect crystal using a standard Monte Carlo simulation code.

description: The article deals with the control modes of physical processes in the technology of laser metal deposition (LMD). The software and hardware implementation of the LMD process control system with laser power control is presented. The system operates in real time with a control cycle duration of 15 ms and allows one to adjust the laser power set in the controller program. The system can be used not only in laboratory or newly created installations, but also for integration into existing LMD systems. It is shown that the use of pulse-width modulation of the laser power allows one to control the shape of the deposited track. It is also shown that under certain parameters of power modulation, it is possible to increase the cooling rate of the melt while maintaining the track width.

description: Smallholder farmers often lack documented land rights to serve as collateral for formal loans, and their livelihoods are inextricably linked to increasingly variable weather conditions. Resulting credit and risk constraints prevent them from making potentially profitable investments in their farms. We implemented a randomized evaluation of the impacts of KhetScore, an innovative credit scoring methodology that uses digital technologies and in particular remote sensing to unlock credit and insurance for smallholders including landless farmers in Odisha, a state in eastern India. In our treatment group, where we offered loans and insurance based on the KhetScore methodology, farmers - and especially women - were more likely to purchase insurance, renew insurance coverage in subsequent years, and borrow from formal sources without substituting formal loans for informal loans. Despite increased borrowing, households in the treatment group faced less difficulty in repaying loans, suggesting that KhetScore loans, bundled with crop insurance, transferred risk and eased the burden of repayment. Moreover, the treatment increased agricultural revenues during the monsoon (kharif) season and reduced costs in the dry (rabi) season, enhancing profitability in both seasons. Positive and significant effects are found not only among baseline credit unconstrained farmers but also quantity rationed farmers, suggesting that KhetScore loans can help overcome supply-side credit constraints. Finally, women in the treatment group reported significantly higher levels of empowerment and mental health, manifested in increased participation in household decision-making and reduced feelings of stress, than women in the control group. In conclusion, digital technologies can contribute substantially to expansion in agricultural credit access, risk management, resilience, and wellbeing among marginalized landless farmers.

description: We present an analysis of the early Kepler observations of the previously discovered transiting planet HAT-P-7b. The light curve shows the transit of the star, the occultation of the planet, and the orbit phase-dependent light from the planet. In addition, phase-dependent light from the star is present, known as "ellipsoidal variations". The very nearby planet (only 4 stellar radii away) gravitationally distorts the star and results in a flux modulation twice per orbit. The ellipsoidal variations can confuse interpretation of the planetary phase curve if not self-consistently included in the modeling. We fit the light curve using the Roche potential approximation and derive improved planet and orbit parameters.
