ABSTRACT Declining natural resources, rising production costs, and diminishing returns from input‐intensive practices threaten the sustainability of smallholder rice systems in Bangladesh. Using a primal system approach and survey data from 1869 rice‐producing households, this study evaluates technical and allocative inefficiency across major agro ...

DQN‐Guided Subset‐Induced OCSVM Kernel Approximation for Imbalanced Anomaly Detection
Anomaly detection under limited normal data remains a fundamental challenge due to severe class imbalance and scarcity of anomalies. We propose a novel framework that reformulates support vector selection in One‐Class SVM as a sequential decision‐making problem.

ABSTRACT The paper compares Hartmut Rosa's resonance theory of “the good life” and Daniel Haybron's psychic affirmation theory of “happiness,” which he differentiates, as a descriptive notion, from “well‐being” as an evaluative notion. Haybron suggests that a central determinant of happiness has to be the somewhat reliable occurrence of positive ...

Factors associated with the weight of individual primal cuts and their inter-relationship in cattle [PDF]
Abstract Input parameters for decision support tools are comprised of, amongst others, knowledge of the associated factors and the extent of those associations with the animal-level feature of interest. The objective of the present study was to quantify the association between animal-level factors with primal cut yields in cattle and to ...

Abstract Much of the current popular and academic literature on the provision of green spaces is dominated by the assumption that ‘nature’ is an unalloyed positive, and that socioeconomic and racial exclusion from access to green spaces is a problem of unequal spatial distribution rather than of the form and content of particular urban designs.

Abstract This paper explores what is happening, for a trainee, when an ethical boundary violation occurs by the analyst with a fellow peer in training. I am approaching this through the Jungian concept of the alchemical vas as I attempt to make meaning of a catastrophic collapse of the analytic work.

Primal-dual algorithms for non-negative matrix factorization with the Kullback-Leibler divergence [PDF]
Non-negative matrix factorization (NMF) approximates a given matrix as a product of two non-negative matrices. Multiplicative algorithms deliver reliable results, but they show slow convergence for high-dimensional data and may be stuck away from local minima.

When Enzymes Mislead: Assessing the Value of MRCP in Suspected Choledocholithiasis
ABSTRACT Background The diagnosis of choledocholithiasis (CDL) requires balancing timely intervention against the risks of unnecessary invasive procedures. Although liver function tests (LFTs) are widely used for risk stratification, their static values and short‐term trends remain poorly defined in predicting persistent common bile duct stones.

Computing Skinning Weights via Convex Duality
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.
