Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review
Advanced Intelligent Systems, EarlyView.This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Cacti with Extremal PI Index [PDF]
, 2016 The vertex PI index $PI(G) = \sum_{xy \in E(G)} [n_{xy}(x) + n_{xy}(y)]$ is a distance-based molecular structure descriptor, where $n_{xy}(x)$ denotes the number of vertices which are closer to the vertex $x$ than to the vertex $y$ and which has been the

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions
Applications in Plant Sciences, EarlyView.Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Aquatic Invertebrates of the Devereux Slough - 2018 [PDF]
, 2020 In 2018, the hardscape construction of NCOS (North Campus Open Space), a restored wetland on the Northern border of COPR (Coal Oil Point Reserve), was completed, thus approximately doubling the overall size of the wetland and offering the rather unique ...

Early evolutionary history of the seed
Biological Reviews, EarlyView.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Convolutional Deblurring for Natural Imaging
, 2019 In this paper, we propose a novel design of image deblurring in the form of one-shot convolution filtering that can directly convolve with naturally blurred images for restoration.

The Journal of Humanistic Counseling, EarlyView.ABSTRACT This article explores obsessive–compulsive disorder (OCD) through the framework of Gestalt therapy, specifically the “dance of reciprocity” model. It integrates phenomenological, aesthetic, and field‐oriented perspectives. Informed by research on attachment styles and emotional processes in OCD, it provides a developmentally and relationally ...

Mathematical Methods in the Applied Sciences, EarlyView.We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

Maximum Zagreb index, minimum hyper-Wiener index and graph connectivity
Applied Mathematics Letters, 2009 AbstractIn this work we show that among all n-vertex graphs with edge or vertex connectivity k, the graph G=Kk∨(K1+Kn−k−1), the join of Kk, the complete graph on k vertices, with the disjoint union of K1 and Kn−k−1, is the unique graph with maximum sum of squares of vertex degrees.
