On bicyclic graphs with maximal energy

open access: yesLinear Algebra and its Applications, 2007
The energy of a graph is the sum the absolute values of its eigenvalues. The main result of the article is the construction of the graph with maximal energy in the set of bicyclic graphs. This result gives a partial solution to Gutman's conjecture for molecular graphs with maximal energy.

Haemodynamic responses to head‐up tilt versus lower‐body negative pressure in type 1 diabetes

open access: yesExperimental Physiology, EarlyView.
Abstract Head‐up tilt (HUT) and lower‐body negative pressure (LBNP) both reduce central blood volume but differ in heart orientation and regional fluid shifts. Whether they evoke comparable cardiovascular regulation when matched for preload remains uncertain.

On the Laplacian Coefficients of Bicyclic Graphs [PDF]

open access: yesUniversal Journal of Applied Mathematics, 2015
In this paper, we investigate how the Laplacian coefficients changed after some graph transformations. So, I express some results about Laplacian coefficients ordering of graphs, focusing our attention to the bicyclic graphs. Finally, as an application of these results, we discuss the ordering of graphs based on their Laplacian like energy.

Endocrine and androgenic response to altitude training in professional cyclists

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

The Connected Detour Numbers of Special Classes of Connected Graphs

open access: yesJournal of Mathematics, 2019
Simple finite connected graphs G=V,E of p≥2 vertices are considered in this paper. A connected detour set of G is defined as a subset S⊆V such that the induced subgraph GS is connected and every vertex of G lies on a u−v detour for some u,v∈S.

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

On the spectral radius of bicyclic graphs

open access: yesBulletin: Classe des sciences mathematiques et natturalles, 2005
The authors determine the graph with maximal spectral radius among connected bicyclic graphs of order \(n\), possessing \(k\) pendent vertices. This is the graph having two triangles with a common vertex at which \(k\) paths of almost equal length are attached.

LiBrain: LLM‐powered Li‐ion battery diagnostics with time‐series‐aware retrieval‐augmented framework for E‐bikes

open access: yesAI Magazine, Volume 47, Issue 3, Fall 2026.
Abstract The rapid proliferation of smart‐city ecosystems has significantly amplified the demand for Li‐ion batteries, which now serve as the primary energy source for sustainable transportation systems such as e‐bikes. Ensuring battery safety and optimal performance is crucial, yet challenging due to complex intrinsic dynamics and extrinsic operating ...

Talking trails: LLM‐enhanced spatiotemporal trajectory modeling for E‐bike delivery route planning

open access: yesAI Magazine, Volume 47, Issue 3, Fall 2026.
Abstract Electric bicycles (e‐bikes) have become the dominant mode of transportation in China's urban instant delivery industry. However, many riders lack the experience to navigate complex traffic networks and diverse road conditions, leading to reduced delivery efficiency.

Move and Play Programme: Perceptions of Paediatric Physiotherapists and Parents of Infants

open access: yesChild: Care, Health and Development, Volume 52, Issue 5, September 2026.
ABSTRACT Introduction Educational videos can improve parent engagement in early childhood development. For widespread adoption, these videos need to be practical and of high quality. This study evaluated how paediatric physiotherapists and parents perceived the educational videos of the ‘Move and Play Programme’.
