description: Item nonresponse is frequently encountered in practice. Ignoring missing data can lose efficiency and lead to misleading inference. Fractional imputation is a frequentist approach of imputation for handling missing data. However, the parametric fractional imputation may be subject to bias under model misspecification. In this article, we propose a novel semiparametric fractional imputation (SFI) method using Gaussian mixture models. The proposed method is computationally efficient and leads to robust estimation. The proposed method is further extended to incorporate the categorical auxiliary information. The asymptotic model consistency and n-consistency of the SFI estimator are also established. Some simulation studies are presented to check the finite sample performance of the proposed method. Supplementary materials for this article are available online.
Implications of Atmospheric Differential Refraction for Adaptive Optics Observations
Creators: name: Roe, Henry G.

Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: Many adaptive optics systems operate by measuring the distortion of the wavefront in one wavelength range and performing the scientific observations in a second, different wavelength range. One common technique is to measure wavefront distortions at wavelengths ~1 micron. The index of refraction of air decreases sharply from shorter visible wavelengths to near-infrared wavelengths. Therefore, because the adaptive optics system is measuring the wavefront distortion in one wavelength range and the science observations are performed at a different wavelength range, residual image motion occurs and the maximum exposure time before smearing of the image can be significantly limited. We demonstrate the importance of atmospheric differential refraction, present calculations to predict the effect of atmospheric differential refraction, and finally discuss the implications of atmospheric differential refraction for several current and proposed observatories.

description: In aspect-level sentiment classification (ASC), it is prevalent to equip dominant neural models with attention mechanisms, for the sake of acquiring the importance of each context word on the given aspect. However, such a mechanism tends to excessively focus on a few frequent words with sentiment polarities, while ignoring infrequent ones. In this paper, we propose a progressive self-supervised attention learning approach for neural ASC models, which automatically mines useful attention supervision information from a training corpus to refine attention mechanisms. Specifically, we iteratively conduct sentiment predictions on all training instances. Particularly, at each iteration, the context word with the maximum attention weight is extracted as the one with active/misleading influence on the correct/incorrect prediction of every instance, and then the word itself is masked for subsequent iterations. Finally, we augment the conventional training objective with a regularization term, which enables ASC models to continue equally focusing on the extracted active context words while decreasing weights of those misleading ones. Experimental results on multiple datasets show that our proposed approach yields better attention mechanisms, leading to substantial improvements over the two state-of-the-art neural ASC models.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Count data is becoming more and more ubiquitous in a wide range of applications, with datasets growing both in size and in dimension. In this context, an increasing amount of work is dedicated to the construction of statistical models directly accounting for the discrete nature of the data. Moreover, it has been shown that integrating dimension reduction to clustering can drastically improve performance and stability. In this paper, we rely on the mixture of multinomial PCA, a mixture model for the clustering of count data, also known as the probabilistic clustering-projection model in the literature. Related to the latent Dirichlet allocation model, it offers the flexibility of topic modeling while being able to assign each observation to a unique cluster. We introduce a greedy clustering algorithm, where inference and clustering are jointly done by mixing a classification variational expectation maximization algorithm, with a branch & bound like strategy on a variational lower bound. An integrated classification likelihood criterion is derived for model selection, and a thorough study with numerical experiments is proposed to assess both the performance and robustness of the method. Finally, we illustrate the qualitative interest of the latter in a real-world application, for the clustering of anatomopathological medical reports, in partnership with expert practitioners from the Institut Curie hospital.

The inverse productivity size relationship: can it be explained by systematic measurement error in self-reported production?

description: This paper revisits the decades-old puzzle of the inverse productivity plot-size relationship (IR), which states that land productivity decrease with increasing plot size in developing countries. While most empirical studies about the IR define yields as self-reported production divided by plot size, this paper complements this approach with an alternative, objective method to estimate yields: crop cuts. Using crop cuts as proxy for yields, the IR in Ethiopia disappears, while the relationship is strong when yields are based on self-reported production. The inverse relationship is even reversed as there exists a weak, positive correlation between plot size and crop cuts. This implies that farmers systematically over report production on small plots and underreport it on larger ones. Our findings suggest that the IR is an artifact of systematic measurement error in self-reported production.

description: Sharecropping is commonly practised in developing countries but the debate over the existence and magnitude of its disincentive effects on productivity remains controversial under competing contracting models. We address the two issues by analysing the effects of sharecropping contracts on tenant's performance in two environments: selection bias into share tenancy due to cultivator heterogeneity and adverse selection from landowner side on land characteristics. Using longitudinal data collected for owner-cum-sharecroppers in Amhara, Ethiopia, controlling for the selection biases, we found significantly negative effects of sharecropping contracts on production outcomes and input provision. However, sharecropping inefficiency can be mitigated by cultivator-specific characteristics as household size, gender and productive assets, making policy suggestions on reducing market imperfections more relevant.

description: This study aims to provide the first brain structural-behavioral correlates underlying age differences in Grooved Pegboard Test (GPT) performance after adjusting for gender, education, quality of life, mental health, and anthropometric variables. We report the data of 210 right-handed participants (20- to 80-year old), who underwent behavioral assessments including GPT, Trail Making Test, and stop-signal task. Magnetic resonance images were acquired to investigate the structural-behavioral correlates of age differences in GPT performance. Age differences in GPT performance were positively associated with visuomotor tracking performance and negatively associated with widespread brain structural measures, including white matter tracts (e.g., commissure, radiation, and association fibers) and gray matter regions in frontal and cingulate regions, parietal, and temporal lobes.

description: The increasing realism and sophistication of text generated by large language models (LLMs) such as ChatGPT, GPT-3, and GPT-4 have introduced substantial challenges in distinguishing between AI-generated and human-authored content. This issue has significant implications across various sectors including education, journalism, cybersecurity, and digital communication ethics. As LLMs evolve rapidly in scale and capability, the ability to detect synthetic text is becoming vital to maintain information integrity, prevent misinformation, and support ethical digital discourse.

Goal. This research aims to develop a lightweight, accurate, and computationally efficient model that can reliably differentiate between AI-generated and human-written texts. The solution targets real-world deployment scenarios where low-latency inference and minimal resource consumption are essential.

Design. To meet these objectives, we fine-tuned MiniLMv2—an efficient transformer distilled from BERT—augmented with a binary classification head. A diverse, domain-balanced dataset of human and AI texts was used to train and evaluate the model. Techniques such as GELU activation, Adam-based optimization, and dropout regularization were employed to enhance generalization and stability. The training pipeline was implemented using the modular and scalable FastAI framework. Our model offers an interpretable and practical solution, contributing to the ongoing discourse on trust, transparency, and accountability in AI-generated content detection.

This work is intended for researchers in NLP, developers creating AI transparency tools, policymakers focused on digital integrity, educators, content moderation teams, and cybersecurity professionals. It also has strong applicability in online learning platforms, digital publishing systems, and real-time moderation pipelines.

Food Consumption/Nutrition/Food Safety

description: Cereals are the major staples in most African countries, where food processing industries are emerging fast. New low-cost extruders allow small enterprises to enter the market for processed cereal products, including instant, fortified and flavored mixes. Before engaging in the marketing of these products, consumers’ interest needs to be assessed. This study used a combination of affective tests and experimental auctions with 200 consumers in Touba, Senegal, to evaluate four new products with conventional millet four as control: instant millet flour, instant millet flour with added mango and carrot extract, and the previous product with added micronutrients from either synthetic or natural origin. During affective tests, consumers made little distinction between the five products for appearance, aroma, taste and overall appreciation. The experimental auctions showed that, without providing additional information on the products, there is no difference in WTP between them. However, after that information is provided, consumers are willing to pay a modest premium for instant flour, and a large premium for added mango and carrot extract and for added micronutrients, but not for micronutrients from natural sources. Income increases overall WTP, while education increases WTP for instant flour. We conclude that there is a potential market for instant and fortified millet flour in Touba, but likely in the higher income and education groups. The increased cost needs to be compared to the premiums consumers are willing to pay. In the next step, the new and promising products could be tested in pilot markets, with target consumers.
Non-invasive Blood Pressure Estimation Using Phonocardiogram

description: This paper presents a novel approach based on pulse transit time (PTT) for the estimation of blood pressure (BP). In order to achieve this goal, a data acquisition hardware is designed for high-resolution sampling of phonocardiogram (PCG) and photoplethysmogram (PPG). These two signals can derive PTT values. Meanwhile, a force-sensing resistor (FSR) is placed under the cuff of the BP reference device to mark the moments of measurements accurately via recording instantaneous cuff pressure. For deriving the PTT-BP models, a calibration procedure including a supervised physical exercise is conducted for each individual. The proposed method is evaluated on 24 subjects. The final results prove that using PCG for PTT measurement alongside the proposed models, the BP can be estimated reliably. Since the use of PCG requires a minimal low-cost hardware, the proposed method enables ubiquitous BP estimation in portable healthcare devices.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The interaction of a magnetic monopole-antimonopole pair depends on their separation as well as on a second "twist" degree of freedom. This novel interaction leads to a non-trivial bound state solution known as a sphaleron and to scattering in which the monopole-antimonopole bounce off each other and do not annihilate. The twist degree of freedom also plays a role in numerical experiments in which gauge waves collide and create monopole-antimonopole pairs. Similar gauge wavepacket scatterings in the Abelian-Higgs model lead to the production of string loops that may be relevant to superconductors. Ongoing numerical experiments to study the production of electroweak sphalerons that result in changes in the Chern-Simons number, and hence baryon number, are also described but have not yet met with success.

description: The Delta I = 1 staggering (odd--even staggering) in octupole bands of light actinides is found to exhibit a ``beat'' behaviour as a function of the angular momentum I, forcing us to revise the traditional belief that this staggering decreases gradually to zero and then remains at this zero value. Various algebraic models (spf-Interacting Boson Model, spdf-IBM, Vector Boson Model, Nuclear Vibron Model) are shown to predict in their su(3) limits constant staggering for this case, being thus unable to describe the ``beat'' behaviour. An explanation of the ``beat'' behaviour is given in terms of two Dunham expansions (expansions in terms of powers of I(I+1)) with slightly different sets of coefficients for the ground state band and the negative parity band, the difference in the values of the coefficients being attributed to Coriolis couplings to other negative parity bands. Similar ``beat'' patterns have already been seen in rotational bands of some diatomic molecules, like AgH.

description: The varying circumstances driven by climate threats and the consequences posed on the environment and humans of dry-land regions, where pastorals and agro-pastorals dominantly live have become the prior policy concerns in Africa. Hence, this study was tended to investigate the effects of various adaptation measures on the income level of pastorals and agro-pastorals in northern Ethiopia. Data were gathered using semi-structured questionnaires including qualitative ideas obtained from group discussants and key informants. The study revealed that repeated droughts caused by climate change left the pastorals and agro-pastorals with herd decimation due to lack of animal feed. In responding this, they applied various adaptation actions such as water harvesting schemes; fodder production, feed purchase, migration, livestock diversification and animal restocking. Using such measures, cattle owners generated income from livestock, cropping, sales of fuel-wood, agricultural wages, remittance and relief aid. Thus, it is concluded that sustainable income creation via various adaptation methods is an important pathway to enable the pastoral and agro-pastoral communities while they respond to the adverse effects of climatic change.

description: We report on the discovery of a hot Saturn-sized planet (9.916 +/- 0.985 R_earth) around a late F star, EPIC 246865365, observed in Campaign 13 of the K2 mission. We began studying this planet candidate because prior to the release of Gaia DR2, the host star was thought to have been a member (> 90% membership probability) of the approximately 1 Gyr open cluster NGC 1817 based on its kinematics and photometric distance. We identify the host star (among three stars within the K2 photometric aperture) using seeing-limited photometry and rule out false positive scenarios using adaptive optics imaging and radial velocity observations. We statistically validate EPIC 246865365b by calculating a false positive probability rate of 0.01%. However, we also show using new kinematic measurements provided by Gaia DR2 and our measured radial velocity of the system that EPIC 246865365 is unassociated with the cluster NGC 1817. Therefore, the long-running search for a giant transiting planet in an open cluster remains fruitless. Finally, we note that our use of seeing-limited photometry is a good demonstration of similar techniques that are already being used to follow up TESS planet candidates, especially in crowded regions.

description: Despite the numerous constraints facing the smallholder pig value chain in Uganda, it has been identified as one of the subsectors with high prospects for pro-poor growth due to the rising demand for pork and pork products. This paper focusses on the smallholder pig value chain governance structures and describes the constraints along the value chain. Awareness of the governance structure of the value chain is important in providing information on the types of interventions that can be targeted to the smallholder actors to upgrade their position in the chain. The findings show that the Uganda pig value chain is characterised by spot market transactions with limited contractual or hierarchical arrangements. Traders participate in horizontal collaboration to improve their competitive position in the value chain. The constraints affecting pig producers comprise pig diseases, low market prices for pig products, lack of reliable market and inaccurate estimation of pig weight at the point of sale. The live pig traders were the most powerful actors in the value chain but still faced challenges such as bad debts, high market prices and lack of enough capital while livestock feed traders predominantly mentioned presence of poor quality feeds in the market. Development of contractual relationships would help to tap domestic and export markets for pork products and reduce uncertainties. Besides, establishing proper breeding program and periodic training of farmers and drug stockists about new drugs in the market and animal husbandry practices would contribute to increased performance of pig industry.

description: Rural households in developing countries face yield risks and seasonal production amidst the desire for stable household consumption. While storage has been cited as one of the ways of smoothing consumption during the lean periods, there is little empirical evidence on the subject. The current study used a generalized propensity score approach to examine the impact of storage on maize consumption smoothing. Maize was found to be the main crop, mostly grown for home consumption. The amount bought increased during the leaner periods when the prices were higher. In addition, the coefficient of variation for total maize consumption for decreased with increase in the length of storage, indicating that indeed storage helps to smoothen consumption across the year and consequently improve household food security.
The Masses of Distant Galaxies from Optical Emission Line Widths

description: Promising methods for studying galaxy evolution rely on optical emission line width measurements to compare intermediate-redshift objects to galaxies with equivalent masses at the present epoch. However, emission lines can be misleading. We show empirical examples of galaxies with concentrated central star formation from a survey of galaxies in pairs; HI observations of these galaxies indicate that the optical line emission fails to sample their full gravitational potentials. We use simple models of bulge-forming bursts of star formation to demonstrate that compact optical morphologies and small half-light radii can accompany these anomalously narrow emission lines; thus late-type bulges forming on rapid (0.5-1 Gyr) timescales at intermediate redshift would exhibit properties similar to those of heavily bursting dwarfs. We conclude that some of the luminous compact objects observed at intermediate and high redshift may be starbursts in the centers of massive galaxies and/or bulges in formation.

Effect of LaNiO3 on the impedance and dielectric properties of CoFe2O4: a high temperature study

description: We report the high temperature impedance and dielectric measurement of the nanocomposites comprising of CoFe2O4 (CFO) and LaNiO3 (LNO) by changing the content of LaNiO3 (0, 5, 10 and 15 %). The aim of the present study is to relate the structural defects expected at the interfaces of the composites with the result of impedance and dielectrics. The result separately shows the grain, grain boundary and electrode relaxation behaviour in the impedance and modulus spectroscopy. As calculated using Arrhenius law it indicates a reduced activation energy of the grain boundary in the presence of LNO compared to pure CFO. This assists the charge carriers for short range hopping across the boundary as reflected from ac conductivity. The dielectric constant at high frequency side manifests the interband transition in both pure CFO and the composite materials. The frequency of the transition can be tuned by LNO content. Thus this detail study will help to understand the relaxation phenomenon and dielectric behaviour in the presence of structural defects and disorder.

description: This thesis explores and compares the national-cultural characteristics of speech etiquette used in family settings in the English and Uzbek languages. The aim of this study is to provide a comprehensive examination of the cultural norms and values that influence communication patterns within families, shedding light on the similarities and differences between these two distinct cultural contexts. By identifying and analyzing the various components of speech etiquette, such as politeness strategies, intergenerational dynamics, and gender roles, this research intends to deepen our understanding of how language use is shaped by cultural factors and to contribute to a cross-cultural understanding of communication practices within the family unit.

description: Whether China continues its business-as-usual investment-driven, environment-polluting growth pattern or adopts an investment and innovation-driven, environmentally sustainable development holds important implications for both national and global environmental governance. Building on a Ramsey-Cass-Koopmans growth model that features endogenous technological change induced by R&D and knowledge stock accumulation, this paper presents an exposition, both analytically and numerically, of the mechanism underlining China’s economic transition from an investment-driven, pollution-intensive to an investment and innovation-driven, environmentally sustainable growth path. We show that if R&D technological innovation is incorporated into China’s growth mechanism, then at some tipping point in time when marginal welfare gain of R&D for knowledge accumulation becomes equalized with that of investment for physical asset deployment, China’s economy will launch capital investment and R&D simultaneously and make a transition to a sustainable growth path along which consumption, capital investment, and R&D have a balanced share of 5: 4: 1, consumption, capital stock, and knowledge stock all grow at a rate of 4.9%, and environmental quality improves at a rate of 2.5%. In contrast, if R&D technological innovation is not harnessed as a new growth engine, then China’s economy will follow its business-as-usual investment-driven growth path along which standalone accumulation of dirty physical capital stock will lead to an more than 200-fold increase in environmental pollution.
Submicroscopic Deterministic Quantum Mechanics

description: So-called hidden variables introduced in quantum mechanics by de Broglie and Bohm have changed their initial enigmatic meanings and acquired quite reasonable outlines of real and measurable characteristics. The start viewpoint was the following: All the phenomena, which we observe in the quantum world, should reflect structural properties of the real space. Thus the scale 10^{-28} cm at which three fundamental interactions (electromagnetic, weak, and strong) intersect has been treated as the size of a building block of the space. The appearance of a massive particle is associated with a local deformation of the cellular space, i.e. deformation of a cell. The mechanics of a moving particle that has been constructed is deterministic by its nature and shows that the particle interacts with cells of the space creating elementary excitations called "inertons". The further study has disclosed that inertons are a substructure of the matter waves which are described by the orthodox wave ψ-function formalism. The concept has allowed resolving the spin problem. The theory, or more exactly, the existence of inertons, has been verified experimentally: in rarefied gases, inerton clouds of atoms' electrons interact with a strong laser pulse; in a solid, atom's inertons induce an additional harmonic potential that contributes to the interatomic interaction (metal specimens and the KIO_3*HIO_3 crystal).
