Triangulations of the 3-sphere with knotted edge

Dionne Ibarra · Daniel V. Mathews · Jessica S. Purcell · Jonathan Spreer

We prove that for any knot $K$, there exists a one-vertex triangulation of the $3$-sphere containing an edge forming $K$. The proof is constructive, and based on fully augmented links. We use our method to produce ``complicated'' simplicial triangulations of the $3$-sphere that we show are smallest possible, up to a co...

An efficient hybrid heuristic for the transmission expansion planning under uncertainty

Yure Rocha · Teobaldo Bulhões · Anand Subramanian · Joaquim Dias Garcia

We address the stochastic transmission expansion planning (STEP) problem under uncertainty in renewable generation capacity and demand. STEP's objective is to minimize total transmission investment and generation costs. To tackle the computational challenges posed by large-scale systems, we propose a heuristic strategy...

Long-term X-ray spectral analysis of Cygnus X-1 using AstroSat

H. Lalthantluanga · Akash Garg · Ranjeev Misra · Vanzarmawii Chhangte · y 1 más

We performed a spectral analysis of long-term observations (2016-2019) of the black hole binary Cygnus X-1 using AstroSat, covering its hard, intermediate, and soft states. During soft states, we found that a typical spectrum fitted with a single Comptonization, a thermal disc, and an iron line yields poor fits and unp...

Algorithmic fairness as a human–technology interaction problem

Aurélie Lemmens

Algorithms shape high-stakes decisions across society. While promising efficiency, algorithms also raise fairness concerns. This article proposes that algorithmic fairness is best understood as a human-technology interaction problem rather than a purely technical challenge. Algorithms can reproduce human biases, amplif...

The asymptotic behavior for divergence elliptic equations in exterior domains with periodic coefficients

Lichun Liang

In this paper, we investigate the asymptotic behavior of solutions for divergence linear elliptic equations in exterior domains with periodic coefficients. Consequently, we generalise the Liouville type result firstly established by Avellaneda and Lin.

A probabilistic risk assessment framework to estimate power system risks for outage planning

Davide Berti · Davood Raoofsheibani · Blazhe Gjorgiev · Roberto Rocchetta · y 1 más

This paper presents a Probabilistic Risk Assessment (PRA) framework for estimating the risk of power system operation under planned outages. The uncertainty in nodal injections and consumptions is represented by scenarios drawn from a copula model that are evaluated via Monte Carlo simulation. For each scenario, the im...

Reactivity-guided experimental design and severity factor development for optimizing the chemical activation of hydrolysis lignin into CO2-adsorbing carbons

Chamseddine Guizani · Virpi Siipola · Fanni Hakanen · Mikko Mäkelä

Hydrolysis lignins (HL) produced from cellulosic ethanol biorefineries can be transformed into high-value activated carbons (ACs) for capturing CO2, offering more lucrative options compared to using them as combustion fuels. Maximizing gravimetric yield and CO2 adsorption performance of ACs made from lignin through che...

Self-awareness and negotiations

Kristina A. Wald

How does directing attention toward oneself, or self-awareness, affect one's performance in a negotiation? This article reviews recent research on self-awareness and discusses the implications of these findings for a negotiator's actions before, during, and after a negotiation. Before a negotiation, self-awareness may...

Artificial intelligence catalyzes antimicrobial peptide design

Yongqiang Liu · Jie Hu · Ning Zhang · Yinqi Bai · y 2 más

With broad-spectrum, low resistance, and multifunctional properties, antimicrobial peptides (AMPs) are promising therapeutic agents against drug-resistant pathogens, yet their discovery and optimization still remain challenging due to the complexity of sequence-function associations. Artificial intelligence (AI), throu...
