description: Periclocystis Iredale, 1937
 Periclocystis Iredale, 1937a: 28. Type species Periclocystis ardeni Iredale, 1937 (OD).
 Description. External morphology: Shell 4.2–4.3 whorls, not glossy, spire and apex flattened, last whorl rapidly descending. Protoconch sculptured with incised spiral grooves; teleoconch with microscopic spiral grooves. Whorl profile rounded above and below evenly convex periphery. Internal walls of early whorls complete; umbilicus open, narrow U-shape. Mantle laps narrow, finger-shaped, very small, not fused, uniform in colour. Mantle lobes very small. Caudal apparatus as for family; caudal foss vertical slit in tail.
 Mantle cavity: As for family. Mantle with no visible minor blood vessels; pigmentation of black and white spots.
 Digestive system: Oesophageal crop absent.
 Genital system: As for family. Carrefour and talon not examined. Free oviduct very long; capsular gland not examined; internal sculpture not examined. Bursa copulatrix inserted on vagina, moderately short, about half spermoviduct length; duct of bursa copulatrix wide, distinguishable from bursa copulatrix, interior not examined. Epiphallus enters penis through simple pore; penis internally covered in flat, ridged, diamondshaped pustules, pilasters absent, diverticulum on penis absent. Penial sheath thick, enclosing only penis; penis retractor muscle attached to epiphallus. Epiphallus internally with longitudinal pilasters. Epiphallic retractor caecum absent. Very short lime-sac present. Spermatophore not present in dissected material.
 Radula: Not examined.
 Remarks. Periclocystis, like Echonitor, is restricted to South Australia. This monotypic genus was separated from Echonitor on the basis of a more flattened shell, dull rather than glossy, with a slightly wider umbilicus and a small, thick, non-reflected columella. No description of the anatomy has been previously published.
 Periclocystis shares with five other genera (Echonitor, Tarocystis, Sheaia, Levidens) the lack of a flagellum and epiphallic caecum but can be distinguished by the flattened, non-glossy shell with a descending last whorl and the distinctive diamond-shaped, ridged pustules covering the inside of the penis.

The Giant Flare of 1998 August 27 from SGR 1900+14: II. Radiative Mechanism and Physical Constraints on the Source

description: (ABBREVIATED) The extraordinary 1998 August 27 giant flare places strong constraints on the physical properties of its source, SGR 1900+14. We make detailed comparisons of the published data with the magnetar model. The giant flare evolved through three stages, whose radiative mechanisms we address in turn. A triggering mechanism is proposed, whereby a helical distortion of the core magnetic field induces large-scale fracturing in the crust and a twisting deformation of the crust and exterior magnetic field. The envelope of the pulsating tail of the August 27 flare can be accurately fit, after ~40 s, by the contracting surface of a relativistically hot, but inhomogeneous, trapped fireball. We quantify the effects of direct neutrino-pair emission, thereby deducing a lower bound ~ 10^{32} G-cm^3 to the magnetic moment of the confining field. The radiative flux during the intermediate ~40 s of the burst appears to exceed the trapped fireball fit. The spectrum and lightcurve of this smooth tail are consistent with heating in an extended pair corona, possibly powered by continuing seismic activity in the star. We consider in detail the critical luminosity, below which a stable balance can be maintained between heating and radiative cooling in a confined, magnetized pair plasma; but above which the confined plasma runs away to local thermodynamic equilibrium. In the later pulsating tail, the best fit temperature equilibrates at a value which agrees well with the regulating effect of photon splitting. The remarkable four-peaked substructure within each 5.16-s pulse provides strong evidence for the presence of higher magnetic multipoles in SGR 1900+14. The corresponding collimation of the X-ray flux is related to radiative transport in a super-QED magnetic field.

description: In the consumer packaged goods (CPGs) industry, consumers base their purchase decisions in part on package size because different package sizes offer different levels of convenience. The heterogeneous preference for package size allows manufacturers to use package size as a competitive tool in order to raise margins in the face of higher production costs. By competing in package sizes, manufacturers may be able to soften the degree of price competition in the downstream market, and raise margins accordingly. In order to test this hypothesis, we develop a structural model of consumer demand, and manufacturers' joint decisions regarding package size and price applied to store-level scanner data for the ready-to-eat breakfast cereal category. While others have argued that manufacturers reduce package sizes as a means of raising unit-prices in a hidden way, we show that package size and price are strategic complements – downsizing causes competitors to lower their prices, which leads to further downsizing, and more price competition until a particularly undesirable equilibrium (from the manufacturers perspective) is reached. Our results suggest that package downsizing is not necessarily the best way to extract surplus from consumers as the existing literature would lead us to believe.

description: Farm input subsidy programs have once again become a popular policy tool that many African governments use to improve agricultural productivity and address rural poverty. Zambia is one of the countries of Sub-Saharan Africa (SSA) that over the past decade has devoted a considerable share of its agricultural budget to the Farmer Input Support Program (FISP). Input subsidy programs have received considerable research attention in recent years. Unfortunately, the issue of late delivery of inputs under government subsidy programs has received little or no research attention even though it has been a longstanding problem in many countries, including Zambia. This paper examined the effects of late delivery of fertilizer on technical efficiency of smallholder maize producers and on foregone national maize output in Zambia. Using cross-sectional household survey data for the 2010/11 agricultural season, a plot-level maize yield response model was estimated using a Stochastic Frontier Approach (SFA) while controlling for the endogeneity of whether farmers received their FISP fertilizer on time. Results indicate that late delivery of fertilizer reduces technical efficiency and maize yield by 4.2%. The estimated results are then extrapolated to quantify the loss in national maize output. The foregone maize output due to late delivery of fertilizer in the 2010/11 farming season was 84,924 metric tons. When valued at the government’s maize purchase price, the forgone income is equivalent to USD 21.2 million. Furthermore, by limiting the sample to only households that obtained fertilizer from FISP, we found that households with large landholding size and high value of productive assets were more likely to receive fertilizer on time, ceteris paribus. It was also found that households with family connections with village headmen/chiefs were more likely to receive fertilizer on time compared to other households.

description: Atomic clocks based on an Al$^+$ ion sympathetically cooled by a laser-cooled alkaline-earth ion have achieved unprecedented accuracy. Here, we investigate theoretically interactions and charge transfer dynamics of an Al$^+$ ion immersed in an ultracold gas of Rb and Sr atoms. We calculate potential energy curves and transition electric dipole moments for the (Al+Rb)$^+$ and (Al+Sr)$^+$ ion-atom systems using coupled cluster and multireference configuration interaction methods with scalar relativistic effects included within the small-core energy-consistent pseudopotentials in Rb and Sr atoms. The long-range interaction coefficients are also reported. We use the electronic structure data to investigate cold collisions and charge transfer dynamics. Scattering of an Al$^+$ ion with alkali-metal or alkaline-earth-metal atom is governed by one potential energy curve whereas charge transfer can lead to several electronic states mixed by the relativistic spin-orbit coupling. We examine the branching ratios resulting from the interplay of the short- and long-range effects, as well as the prospects for the laser-field control and formation of molecular ions. We propose to employ the atomic clock transition in an Al$^+$ ion to monitor ion-atom scattering dynamics via quantum logic spectroscopy. The presented results pave the way for the application of atomic ions other than alkali-metal and alkaline-earth-metal ones in the field of cold hybrid ion-atom experiments.

subject: PhD

description: This thesis examines the private madhouses of Somerset, Dorset, Devon, and Wiltshire during a period of great transition within the existing lunacy care landscape. Many madhouses pre-dated county asylums in provision for the pauper mentally ill, including in the south west. Madhouses operated as an enterprise, unlike the parish overseen county asylums. This led to a lack of regulations in care. The Lunacy Commission was formed as part of the 1828 Madhouse Act. This led to a series of inspections of all asylums throughout England for the first time. At this time, Devon and Somerset had disproportionally high rates of mentally unwell pauper patients compared to the rest of England. Despite this, no county asylum was built in either of these counties until 1845. Newspaper reports cited magistrates’ claims that they were not needed because of private asylums operating in the region. Private asylums are often associated with wrongful confinement and mistreatment of patients. This reputation was expressed at the time in popular culture and exerts a profound legacy even today. There has been much academic interest in the care of the mentally unwell in this period, yet private establishments remain under-researched. This is especially true of the south west, aside from Leonard Smith’s research on the proprietors of Bristol private asylums (2008 and 2016). This lack of research downplays their importance as providers of care for both private and pauper patients. The south west asylums also hold links to the Quaker-led reforms in mental health care of the 1790s. This thesis begins with an examination of the cultural reputation of madhouses, using examples from England as a whole but relating to the southwest where applicable, and then moves to frame the network of asylums within the south west. This includes examinations of patient care, treatments, staff and proprietors. As many madhouses did not keep or preserve patient records (which would usually be a logical starting point), this thesis uses a novel approach in the combination of different types of source material to create quantitative data for analysis as well as qualitative. Sources include, but are not limited to, extensive archival material, admissions records, family history, and newspapers. Family and local history methods were also used to create a prosopography of asylum proprietors in order to gain a better understanding of their motivations and practice.

description: The transformation of the global agrifood system is characterized by the increasing importance of food safety and quality standards. This trend is challenging farmers in countries like Guatemala as they lack necessary skills and assets. This study analyzes the determinants of Globalgap adoption with a special focus on financial literacy. The concept has not been considered yet in technology adoption studies. Our results indicate that financial literacy indeed has a significant impact on the probability to adopt the standard. Our results hold practical implications for development interventions targeting technology and standard adoption and smallholder market integration.

description: We examine the optimal management of emission permit markets when banking but not borrowing of permits is allowed. The regulator maximizes expected social welfare through an optimal allocation rule in an infinite horizon setting. The policy is second-best as the emission cap is set before the uncertainty about the current state of the economy is resolved. In this setting, the role of banking is to decrease the regulator’s risk as it generates an endogenous price floor in the permit markets. We show that the regulator’s optimal policy adjusts the emissions cap irrespective of the existing number of permits in the bank, with the implication that the regulator neutralizes the effect of the existing bank on future permit prices. We derive the optimality conditions for the second-best emission cap with banking and solve the model analytically in the case of IID shocks. Our results show that the discount factor together with the slopes of the marginal damages and benefits determine the welfare gains from allowing baking of permits. Finally, to address the current state of the EU Emission Trading Scheme (EU ETS) and guide the design of future permit markets, we solve the model numerically with persistent shock process and show that the optimal emission cap is positively correlated with business cycles, meaning that during downturns the regulator should tighten the cap. The expected emissions and permit prices also correlate positively with economic activity

description: Image-based fiducial markers are useful in problems such as object tracking in cluttered or textureless environments, camera (and multi-sensor) calibration tasks, and vision-based simultaneous localization and mapping (SLAM). The state-of-the-art fiducial marker detection algorithms rely on the consistency of the ambient lighting. This paper introduces LiDARTag, a novel fiducial tag design and detection algorithm suitable for light detection and ranging (LiDAR) point clouds. The proposed method runs in real-time and can process data at 100 Hz, which is faster than the currently available LiDAR sensor frequencies. Because of the LiDAR sensors' nature, rapidly changing ambient lighting will not affect the detection of a LiDARTag; hence, the proposed fiducial marker can operate in a completely dark environment. In addition, the LiDARTag nicely complements and is compatible with existing visual fiducial markers, such as AprilTags, allowing for efficient multi-sensor fusion and calibration tasks. We further propose a concept of minimizing a fitting error between a point cloud and the marker's template to estimate the marker's pose. The proposed method achieves millimeter error in translation and a few degrees in rotation. Due to LiDAR returns' sparsity, the point cloud is lifted to a continuous function in a reproducing kernel Hilbert space where the inner product can be used to determine a marker's ID. The experimental results, verified by a motion capture system, confirm that the proposed method can reliably provide a tag's pose and unique ID code. The rejection of false positives is validated on the Google Cartographer indoor dataset and the Honda H3D outdoor dataset. All implementations are coded in C++ and are available at: https://github.com/UMich-BipedLab/LiDARTag.

description: What are global and diffuse risks? How should we think about their potential to turn into threats that overwhelm societal resilience in areas of limited statehood, precipitating violent conflict and governance breakdown? This working paper explores these questions in two sequential steps. First, it shows that existing explanations at the onset of violent conflict and governance breakdown remain focused on local conditions and immediate “bad neighbourhood” effects, neglecting global and diffuse risks. In a highly interconnected and interdependent world such neglect represents a fundamental omission with substantial theoretical and policymaking costs. Global and diffuse risks must be conceptualized, evaluated, and systematically integrated into predictive models, preparedness-efforts, and resilience-building strategies. Secondly, it articulates and explores a five-cluster typology of global and diffuse risks. It is only by taking global and diffuse risks seriously as explanatory variables at the onset of violent conflict and governance breakdown that the EU can make genuine progress in developing a long-term resilience-building strategy.

description: This study proposes a new method to impute for ordinal missing data found in the household section of the Agricultural Resource Management Survey (ARMS). We extend a multivariate imputation method known as Iterative Sequential Regression (ISR) and make use of cut points to transform these ordinal variables into continuous variables for imputation. The household section contains important economic information on the well-being of the farm operator’s household, asking respondents for information on off-farm income, household expenditures, and off-farm debt and assets. Currently, the USDA's Economic Research Service (ERS) uses conditional mean imputation in the household section, a method known to bias the variance of imputed variables downward and to distort multivariate relationships. The new transformation of these variables allows them to be jointly modeled with other ARMS variables using a Gaussian copula. A conditional linear model for imputation is then built using correlation analysis and economic theory. Finally, we discuss a Monte Carlo study which will randomly poke holes in the ARMS data to test the robustness of our proposed method. This will allow us to assess how well the adapted ISR imputation method works in comparison with two other missing data strategies, conditional mean imputation and a complete case analysis.

Flores (2001) added the following constant characters at the tribe level: base of mandible two times higher with respect to apex, prothorax semimobile, and distance between meso- and metacoxae exceeding half mesocoxal length.

description: In this work, we present a second-order nonuniform time-stepping scheme for the time-fractional Allen-Cahn equation. We show that the proposed scheme preserves the discrete maximum principle, and by using the convolution structure of consistency error, we present sharp maximum-norm error estimates which reflect the temporal regularity. As our analysis is built on nonuniform time steps, we may resolve the intrinsic initial singularity by using the graded meshes. Moreover, we propose an adaptive time-stepping strategy for large time simulations. Numerical experiments are presented to show the effectiveness of the proposed scheme. This seems to be the first second-order maximum principle preserving scheme for the time-fractional Allen-Cahn equation.

description: This research presents a set of alternative trade policy scenarios for the long term outlook of the Republic of South Africa (RSA) poultry sector. Consumer demand for poultry has risen dramatically in the past twenty years, but domestic output has not been able to keep pace, and imports have been rising. In a drive towards self-sufficiency, the South African Government has raised tariffs on higher value chicken cuts, including anti-dumping duties imposed on U.S. chicken legs in 2000. The U.S. poultry industry is demanding that the duties be lifted and is attempting to link renewal of AGOA to improved access for U.S. poultry. This analysis finds that if the duties on U.S. poultry are lowered to the MFN level of 37 percent, the U.S. could capture 35 percent of the South African market.

description: We present the first measurements of clustering in the Sloan Digital Sky Survey (SDSS) galaxy redshift survey. Our sample consists of 29,300 galaxies with redshifts 5,700 km/s < cz < 39,000 km/s, distributed in several long but narrow (2.5-5 degree) segments, covering 690 square degrees. For the full, flux-limited sample, the redshift-space correlation length is approximately 8 Mpc/h. The two-dimensional correlation function ξ(r_p,π) shows clear signatures of both the small-scale, ``fingers-of-God'' distortion caused by velocity dispersions in collapsed objects and the large-scale compression caused by coherent flows, though the latter cannot be measured with high precision in the present sample. The inferred real-space correlation function is well described by a power law, ξ(r)=(r/6.1+/-0.2 Mpc/h)^{-1.75+/-0.03}, for 0.1 Mpc/h < r < 16 Mpc/h. The galaxy pairwise velocity dispersion is σ_{12} ~ 600+/-100 km/s for projected separations 0.15 Mpc/h < r_p < 5 Mpc/h. When we divide the sample by color, the red galaxies exhibit a stronger and steeper real-space correlation function and a higher pairwise velocity dispersion than do the blue galaxies. The relative behavior of subsamples defined by high/low profile concentration or high/low surface brightness is qualitatively similar to that of the red/blue subsamples. Our most striking result is a clear measurement of scale-independent luminosity bias at r < 10 Mpc/h: subsamples with absolute magnitude ranges centered on M_*-1.5, M_*, and M_*+1.5 have real-space correlation functions that are parallel power laws of slope ~ -1.8 with correlation lengths of approximately 7.4 Mpc/h, 6.3 Mpc/h, and 4.7 Mpc/h, respectively.

description: Veterinarians need to know which services face inelastic or elastic demand to successfully raise revenues to cover rising costs or to profitably increase market share. This study documents our attempts to model market demand for the service that accounts for the largest share of veterinary revenue—canine wellness visits—and to provide insights about the patronage-alienating effects of the sector’s recent aggressive pricing strategies.

description: The Neoclassical theory of production establishes a dual relationship between the profit value function of a competitive firm and its underlying production technology. This relationship, commonly referred to as duality theory, has been widely used in empirical work to estimate production parameters without the requirement of explicitly specifying the technology. We analyze the ability of this approach to recover the underlying production parameters. We compute the data generating process by Monte Carlo simulations such that the true technology parameters are known. Employing widely used datasets, we calibrate the data generating process to yield a dataset featuring important characteristics of U.S. agriculture. We compare the estimated production parameters with the true (and known) parameters by means of the identities between the Hessians of the production and profit functions. We conclude that, when the dataset bears minimum sources of noise, duality theory is able to recover the true parameters with reasonable accuracy. Also, that when it is employed in time series coming from an aggregation of technologically heterogeneous firms, the parameters recovered are close to the firm at the median of the distribution. The proposed calibration sets the basis for analyzing the performance of duality theory approaches when datasets used by practitioners are subject to other observed and unobserved sources of noise.

description: Το Πρόβλημα Δρομολόγησης Οχημάτων (ΠΔΟ) αποτελεί αναπόσπαστο κομμάτι της Εφοδιαστικής Αλυσίδας λόγω της συνεχώς αυξανόμενης κίνησης στον τομέα του εμπορίου και όχι μόνο παγκοσμίως. Ανά τα χρόνια έχει μελετηθεί αρκετά σταθμίζοντας διαφορετικό παράγοντα κάθε φορά ανάλογα με τις ανάγκες και τους περιορισμούς που τίθενται. Η συγκεκριμένη εργασία επιχειρεί να προσαρμόσει το πρόβλημα στις οικολογικές συνθήκες της εποχής μας δημιουργώντας ένα «πράσινο» ΠΔΟ-“Green VRP” όπου ελαχιστοποιείται η κατανάλωση ενέργειας του συστήματος. Μιμούμενοι τη φύση και πιο συγκεκριμένα τη συμπεριφορά των μυρμηγκιών αναπτύσσεται κώδικας σε προγραμματιστικό περιβάλλον Matlab με σκοπό τη βελτιστοποίηση των διαδρομών των οχημάτων λαμβάνοντας υπόψη τον χρόνο εξυπηρέτησης και τη χωρητικότητα του κάθε οχήματος με γνώμονα το ενεργειακό αποτύπωμα.
description: The Vehicle Routing Problem (VRP) is an integral part of the Supply Chain due to the ever-increasing traffic in the trade sector and not only worldwide. Over the years it has been studied a lot, weighing a different factor each time depending on the needs and constraints. This paper attempts to adapt the problem to the ecological conditions of our time by creating a "Green VRP" where the energy consumption of the system is minimized. By imitating nature and more specifically the behavior of ants, a code is developed in Matlab programming environment with the aim of optimizing vehicle routes while taking into account the service time and capacity of each vehicle also considering the energy footprint.

description: In this work we present the results of a search for continuous gravitational waves from the Galactic Center using LIGO O2 data. The search uses the Band-Sampled-Data directed search pipeline, which performs a semi-coherent wide-parameter-space search, exploiting the robustness of the FrequencyHough transform algorithm. The search targets signals emitted by isolated asymmetric spinning neutron stars, located within 25-150 parsecs from the Galactic Center. The frequencies covered in this search range between 10 and 710 Hz with a spin-down range from $-1.8\times10^{-9}$ to $3.7\times10^{-11}$ Hz/s. No continuous wave signal has been detected and upper limits on the gravitational wave amplitude are presented. The most stringent upper limit at $95\%$ confidence level, for the Livingston detector, is $\sim 1.4 \times 10^{-25}$ at frequencies near 160 Hz. To date, this is the most sensitive directed search for continuous gravitational-wave signals from the Galactic Center and the first search of this kind using the LIGO second observing run.
