Exploration of k-edge-deficient temporal graphs in linear time

Ivan Lahtin · Viktor Zamaraev

We study the Temporal Exploration problem, where an agent must visit all vertices of a temporal graph while traversing at most one available edge per time step. Unlike static graphs, which can be explored in linear time, temporal constraints can substantially increase exploration time even when every snapshot of the gr...

Glycerol conversion to acetol catalyzed by aluminum-free Zr-beta zeolite: High selectivity and coke tolerance

da Silva, Ariel J.T. · Júnior, Marcos · da Costa, Theogyna R.R.T. · Oliveira, Daniele · y 5 más

Zr-Beta zeolite containing exclusively Lewis acid sites (LAS) was synthesized and its catalytic performance in glycerol dehydration was compared with that of Al-Beta zeolite, which possesses both Brønsted acid sites (BAS) and LAS. Distinct differences in catalytic behavior were observed depending on the nature of the a...

The influential first offer: How to advance a negotiation classic by integrating features, mechanisms, and outcomes

David D. Loschelder · Hannes M. Petrowsky

Six decades of research and hundreds of effects have identified robust first-offer advantages and disadvantages. Too assertive an offer can alienate the opposing negotiator, elevate the impasse risk, as well as impair the relationship and outcome satisfaction. In contrast, first offers can also beneficially anchor nego...

Beyond myocardial infarction: Point-of-care cardiac troponin biosensors for heart failure prognosis and remote monitoring

Naregalkar, Akshay Rangnath · K, Sankar · Puja S, Agrawal · Hrushikesh Madhukar, Panchabudhe · y 5 más

Heart failure (HF) is a long-term condition that often causes repeated hospital visits and requires close monitoring. Cardiac troponin I (cTnI) and cardiac troponin T (cTnT) are widely known as markers of myocardial infarction, but in HF they can also show ongoing heart-muscle injury, disease progression, and poor prog...

Assessment of heat, electricity, and biochar polygeneration potential in an existing biomass-fired moving grate boiler used for district heating

Leteng Lin · Wanja Thelin · Truong Nguyen

This study evaluates the techno-economic and environmental potential of retrofitting a 3 MWth biomass-fired moving-grate boiler in Sweden, for polygeneration of district heat, electricity, and biochar through direct biochar integration. The retrofit suppresses late-stage char oxidation to recover solid carbon as biocha...

The effect of augmented protein intake on nitrogen balance: A nested cohort study of the TARGET protein trial

Anis, Chaba · Atthaphong, Phongphithakchai · Akinori, Maeda · Sofia, Spano · y 23 más

The impact of augmenting enteral protein delivery on nitrogen balance, urea generation, and kidney function in critically ill patients remains poorly defined. This study aimed to investigate these effects in a nested cohort within the TARGET Protein trial.We conducted a single-center study nested within a cluster rando...

From RNA design to delivery: Computational strategies for functional RNA therapeutics

Yiming, Wang · Shengxin, Tong · Xin, Wang · Xiaowen, Jin · y 2 más

RNA therapeutics provide a revolutionary means of treating a variety of diseases by precisely regulating gene expression and protein synthesis, with great medical significance. However, there are three key challenges to its clinical application: the inherent instability of RNA, the need for controlled regulation of RNA...

Music in early childhood: Perception, action, and social experience

Marcel Zentner

Research on early musical development has expanded beyond perceptual abilities to encompass movement, social interaction, and broader developmental processes. This Opinion article highlights three themes that illustrate this evolution: the relation between rhythm perception and movement, the role of music in caregiver-...

Multimodal interpretation of notation

Hewitt, D · Ingram, J

Challenges related to the teaching and learning of formal notation in school mathematics are widely documented, and specifically in relation to the underlying mathematical structures that the notation is intended to convey. In this article, we draw on embodied cognition to examine the interactions among three students...

Affinization of dendriform D-bialgebras, Lie bialgebras and solutions of the classical Yang-Baxter equation

Bo Hou

In this paper, we mainly discuss how to use dendriform $\md$-bialgebras to construct Lie bialgebras and the relationship between the solutions of their corresponding Yang-Baxter equations. We provide two methods for obtaining Lie algebras from dendriform algebras using the tensor product with perm algebras, one by mean...
