Chytrids enhance Daphnia fitness by selectively retained chytrid‐synthesised stearidonic acid and conversion of short‐chain to long‐chain polyunsaturated fatty acids

open access: yesFreshwater Biology, Volume 68, Issue 1, Page 77-90, January 2023., 2023
Abstract Chytrid fungal parasites convert dietary energy and essential dietary molecules, such as long‐chain (LC) polyunsaturated fatty acids (PUFA), from inedible algal/cyanobacteria hosts into edible zoospores. How the improved biochemical PUFA composition of chytrid‐infected diet may extend to zooplankton, linking diet quality to consumer fitness ...

Identification and quantification of selected metabolites in differently pigmented leaves of lettuce (Lactuca sativa L.) cultivars harvested at mature and bolting stages

open access: yesBMC Chemistry, 2019
Background Identification and screening of cultivars rich in bioactive phytoconstituents can be potentially useful to make nutrient-dense dishes and in medicinal formulations. In this study, we have identified, characterized and quantified caffeoylquinic

Random Directional Attack for Fooling Deep Neural Networks [PDF]

open access: yesarXiv, 2019
Deep neural networks (DNNs) have been widely used in many fields such as images processing, speech recognition; however, they are vulnerable to adversarial examples, and this is a security issue worthy of attention. Because the training process of DNNs converge the loss by updating the weights along the gradient descent direction, many gradient-based ...

Effects of soil physics, chemistry, and microbiology on soil carbon sequestration in infertile red soils after long‐term cultivation of perennial grasses

open access: yesGCB Bioenergy, Volume 15, Issue 2, Page 239-253, February 2023., 2023
Long‐term cultivation of Miscanthus and Saccharum arundinaceum increased soil organic carbon stock in infertile red soils. Soil pH is the main factor affecting soil carbon stock in red soils. Soil copiotrophic and oligotrophic microbes significantly shaped by the cultivation of perennial grasses. Abstract Determining the effect of perennial energy crop

Stochastic Turing pattern formation in a model with active and passive transport [PDF]

open access: yesarXiv, 2020
We investigate Turing pattern formation in a stochastic and spatially discretized version of a reaction diffusion advection (RDA) equation, which was previously introduced to model synaptogenesis in \textit{C. elegans}. The model describes the interactions between a passively diffusing molecular species and an advecting species that switches between ...

Serum metabolic and microbial profiling yields insights into promoting effect of tryptophan‐related metabolites for health longevity in centenarians

open access: yesiMeta, EarlyView.
Schematic representation of the design. Tryptophan metabolism is enriched in serum metabolites and gut microbiota of centenarians, potentially contributing to healthy longevity. A key tryptophan metabolite 5‐methoxyindoleacetic acid (5‐MIAA) is linked to the Christensenellaceae R‐7 group and exhibits effects of delaying cell senescence, promoting ...

Effect of brushing force on the abrasive dentin wear using slurries with different abrasivity values

open access: yesInternational Journal of Dental Hygiene, Volume 21, Issue 1, Page 172-177, February 2023., 2023
Abstract Objective The aim of this study was to investigate the resulting abrasive dentin wear using abrasive slurries with different RDA values and applying increasing brushing forces. Methods Forty‐five bovine incisors were randomly allocated in three groups (A, B, C, n = 15).

FCM-RDpA: TSK Fuzzy Regression Model Construction Using Fuzzy C-Means Clustering, Regularization, DropRule, and Powerball AdaBelief [PDF]

open access: yesInformation Sciences, 574:490:504, 2021, 2020
To effectively optimize Takagi-Sugeno-Kang (TSK) fuzzy systems for regression problems, a mini-batch gradient descent with regularization, DropRule, and AdaBound (MBGD-RDA) algorithm was recently proposed. This paper further proposes FCM-RDpA, which improves MBGD-RDA by replacing the grid partition approach in rule initialization by fuzzy c-means ...
