Student Loss: Towards the Probability Assumption in Inaccurate Supervision

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2023
<p>Noisy labels are often encountered in datasets, but learning with them is challenging. Although natural discrepancies between clean and mislabeled samples in a noisy category exist, most techniques in this field still gather them indiscriminately, which leads to their performances being partially robust.

Accurate Approximation for Resource Queuing Systems with Losses and Signals

Mathematics
We consider a queuing system with a finite number of servers and a finite pool of resources, where an arriving customer requires a server and random number of resources.

Simulation Modelling of Multiservice Switched Networks Carrying Unicast and Multicast Traffic with Priorities

Transport and Telecommunication
Today’s computer and telecommunications networks, irrespective of the technical solutions and technologies used to build them, are multi-service in nature. The modelling of networks and nodes in such networks is still an important research problem.

On loss probabilities in presence of redundant packets with random drop [PDF]

Performance Evaluation, 2002
We study the loss probabilities of messages in an M/M/1/K queueing system where in addition to losses due to buffer overflow there are random losses on the incoming and outgoing links. We focus on the influence of adding redundant packets to the messages. We obtain analytical results that allow us to investigate when does adding redundancy decrease the

Effectiveness of a Novel Low‐Density Lipoprotein Apheresis Device Rheocarna in Patients Undergoing Hemodialysis With Chronic Limb‐Threatening Ischemia: A Single‐Center Retrospective Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic limb‐threatening ischemia (CLTI) is a severe form of lower‐extremity artery disease characterized by distal lesions and microcirculatory impairment, limiting revascularization efficacy. Rheocarna is a direct hemoperfusion low‐density lipoprotein (LDL) adsorption device with potential rheological and anti‐inflammatory ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Eliciting expert judgement for the probability of AUV loss in contrasting operational environments [PDF]

, 2007
Each time an autonomous underwater vehicle (AUV) is used in the sea there is a non-zero probability of loss. Quantifying probability of loss is not an exact science; therefore much depends on the fault history of the vehicle, the operational environment ...
