A Systematic Literature Review on Machine Learning for Intrusion Detection Systems

The use of Artificial Intelligence (AI) and Machine Learning (ML) in cybersecurity, especially for creating Intrusion Detection Systems (IDSs), has become increasingly important. These systems are essential for detecting malicious behaviour, identifying network issues, and stoppi...

An AI-driven reconstruction of global surface temperature with emphasis on refining the Antarctic record

Abstract. Accurate estimates of long-term surface temperature (ST) changes are fundamental not only for assessing observed warming, but also for improving the reliability of future climate projections. However, substantial missing information in global ST datasets, remains a majo...

Asymmetry in carbon cycle feedbacks and transient climate response under positive and negative CO 2 emissions

Abstract. Most emissions scenarios consistent with limiting warming to well below 2 °C above pre-industrial levels rely on carbon dioxide removal to offset residual positive emissions or achieve net-negative emissions. While carbon cycle and climate metrics are well quantified fo...

Not all cores are equal: Phase-space origins of dynamical friction, stalling and buoyancy

Dynamical friction governs the orbital decay of massive perturbers within galaxies and dark matter halos, yet its standard Chandrasekhar formulation fails in systems with cores of (roughly) constant density, where inspiral can halt or even reverse, phenomena known respectively as...

FewBodyToolkit.jl: A Julia package for solving quantum few-body problems

Few-body physics explores quantum systems of a small number of particles, bridging the gap between single-particle and many-body regimes. To provide an accessible tool for such studies, we present FewBodyToolkit.jl, a Julia package for quantum few-body simulations. The package su...

Rethinking Mean Square Error: Information, Generalized Estimation, and the James–Stein Paradox

The James–Stein estimator’s dominance over maximum likelihood in mean square error has been called a paradox because maximum likelihood is known to be superior in many other respects. One response, due to Efron, is to question maximum likelihood. Another is to question MSE. We pu...

Gathering input for a mental health intervention based on recovery narratives: a focus group study

Recovery narratives (RNs) could potentially be beneficial for service users, leading to hope and a sense of recognition. It remains understudied how to adequately implement these in mental health treatment. To gather input for the development of a RN intervention, we organized fo...

Blood flow coordinates collective endothelial cell migration during vascular plexus formation and promotes angiogenic sprout regression via vegfr3/flt4

Nascent vascular networks adapt to the increasing metabolic demands of growing tissues by expanding via angiogenesis. As vascular networks expand, blood vessels remodel, progressively refining vascular connectivity to generate a more haemodynamically efficient network. This is dr...

Accumulation of stranded plastic objects and other artefacts at Inaccessible Island, central South Atlantic Ocean

During 1987 a survey of macro-artefacts (>10 mm diameter) was conducted along a 900 m boulder beach at the western point of Inaccessible Island, central South Atlantic Ocean. This repeated the survey made at the same site during 1984, when the highest density of artefacts at the...

The WTF-Zone in the Seminar Room

A didactic sketch about a student who genuinely understands the core concepts of her course — intuitively, in her own language — but lacks the formal vocabulary for them. She explains usability, the Tichy zone model, and the WTF Zone in her own words: accurate in substance, entir...

The WTF-Zone on the Porch

A didactic sketch about an educated man in Georgia who attempts to read a translated course script on instructional design — and fails completely. Not out of laziness, not out of ignorance, but because the script offers no point of entry. The sketch illustrates the WTF Zone as a...

Calibrating understanding in interaction

Abstract This study examines how Mandarin Chinese speakers deploy candidate understandings in other-initiated repair in everyday interaction. Drawing on 15 hours of naturally occurring conversation, the analysis shows that candidate understandings recurrently emerge when some asp...

Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Abstract Top‐down studies of methane (CH 4 ) emissions often use the average ethane‐to‐methane (C 2 /C 1 ) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH 4 sources (ruminants, wetlands, landfills, and other methanogenic sou...

Designing multi‐site studies for external validity: Site selection via synthetic purposive sampling

Abstract Multi‐site/context studies have become popular strategies to address the most common and challenging external validity concerns about contexts. Under such studies, scholars conduct causal studies in each site and evaluate whether findings generalize across sites. Despite...

Cognitive Biology: The Physics, the J-Space and the Organ Code

This paper deals with the Organ Code, the cascade of structures that derive from the eigenmodes of the laplacians of the body, head and various organs. This is linked to the Foundational Model of Anatomy and the J-space recently discovered in LLM's by Anthropic. In addition, the...

How large does chi-squared get by chance? A measured null distribution for the combination step of Ellis et al.

Ellis et al. [Phys. Rev. D 99, 083009 (2019)] combine the K-reduced distributions of eight Fermi-LAT gamma-ray bursts into a joint bound on the scale of linear Lorentz violation. The combination yields a raw chi-squared of 261, from which they conclude that the sources are not id...

An explicit initial Θ-datum with mixed reduction at a split prime

We exhibit an explicit initial Θ-datum in the sense of Mochizuki, IUT I, Definition 3.1: an elliptic curve in Legendre form over Q(√5) with ℓ = 7, for which the rational prime 211 splits in the field of moduli, so that one place of multiplicative and one place of good reduction l...

Global Regularity and Uniform H 1 A Priori Estimates for the Three-Dimensional Incompressible Navier–Stokes Equations under Structural Directional Vorticity Constraints

Now I am exploring the Nonlinear term interaction and I add more terms to the vorticity, additionally to the Beltrami core. Then generalized the idea to 4-term interaction, based on other natural systems which are similar to the turbulence phenomena.
