Factored lifts of graphs and their spectra: the Abelian case
In this paper, we introduce the concept of factored lift, associated with a combined voltage graph, as a generalization of the lift graph. We present a new method for computing all the eigenvalues and eigenspaces of factored ...
Delayed flowering time when combining warm temperature and short days in barley
Time to flowering results from the interaction between genotypic and environmental factors. In a field study, flowering of spring barley was delayed in a warmer growing season, particularly in an early sowing under short ...
Physicochemical properties and 3D printability of pregelatinized corn starch were modulated through pulsed electric fields and ultrasonic treatments
While US and PEF treatments have been studied for native corn starch, their effects on the 3D printing behavior of pregelatinizedcorn starch (PGCS) remain largely unexplored. This study is among the first to link these ...
Proposal for a social media-focused emergency communications protocol based on a scoping review and expert validation
Introduction: Social media platforms play a crucial role in crisis and emergency communication by institutions and traditional media. However, evidence suggests that the use of social media for such purposes remains ...
From Theory to Practice: A Methodology Article Describing the Eight-Stage Health Education Planning Instrument in Community Health Education
Background/Objectives: This methodology article describes the development and application of a structured planning instrument for community health education interventions. Community health education can strengthen population ...
Accesibilidad, exclusión y profesiones lingüísticas: la traducción y la interpretación desde la discapacidad
Este artículo aborda una cuestión poco explorada en el ámbito de las profesiones lingüísticas: la accesibilidad en la formación y el ejercicio de la traducción y la interpretación para personas con discapacidad. Aunque los ...
Geografías del habitar desigual: fragmentación vivida y trayectorias cotidianas en Lleida
Este artículo analiza cómo se manifiestan las desigualdades urbanas a través de las trayectorias cotidianas, los usos diferenciales del espacio y las relaciones asimétricas entre grupos sociales en contextos de proximidad ...

Bring your animals: provenance and diet from the Iron Age mass animal sacrifice at Casas del Turuñuelo (Guareña, Spain)
The excavations at the Tartessian monumental building of Casas del Turuñuelo (Guareña, Spain) uncovered the remains of a special event that took place before the intentional closure and burial of the building under an earth ...
Lymphoid Organ Architecture and Hematopoiesis Disruption in Spinal Muscular Atrophy: Therapeutic Rescue by SMN Restoration
Spinal muscular atrophy (SMA) is a neuromuscular disorder caused by loss of the SMN1 gene, reduced levels of SMN protein, and motor neuron degeneration. However, increasing evidence shows that SMA is a multisystemic disease ...
Acompanyar per avaluar. L’impacte d’instruments i estratègies d’avaluació formadora en Ciències Socials. Intervenció educativa en un institut de secundària
En aquest treball, a través d’un estudi de cas, s’exposa i analitza l’impacte de la intervenció realitzada a la matèria de Ciències Socials en un grup de tercer d’ESO al llarg d’una Situació d’Aprenentatge en què s’han ...
Evaluating the effects of the leptin receptor gene on pigs and pork
El receptor de la leptina és un receptor d’alta afinitat que s'uneix a la leptina, una hormona clau que regula la ingesta d'aliments i l'equilibri energètic en mamífers. Les mutacions defectuoses en el gen del receptor de ...
Physiological bases of wheat grain weight response to heat waves: Post-anthesis sensitivity and responses to source-sink manipulations in contrasting cultivars
The companion paper reported that two contemporary cultivars differed constitutively in their average grain weight (AGW) and in their sensitivity to heat waves (HW). It is relevant to elucidate whether the effects of HW ...
Boosting the phytochemical yield and antioxidant activity of Camelina sativa (L.) Crantz sprouts by application of moderate salinity to the germination substrate
This work aimed to test the elicitation effect of salinity on the phytochemical content and antioxidant activity of camelina sprouts. Five camelina cultivars (ALBA, CO46, CCE43, JOELLE, VERA) were sprouted with NaCl solutions ...
Xylem pit anatomy and minimum leaf conductance drive drought mortality in Pinus pinaster
Drought‐triggered forest die‐off events are commonly attributed to hydraulic failure, carbon starvation, or a combination of thetwo. Nevertheless, the anatomical and physiological traits that make trees vulnerable to drought ...
The Diabetes-Pancreatic Cancer Risk Relationship over Time: A Systematic Review and Meta-Analysis
Background/Objectives: The relationship between diabetes and pancreatic cancer (PCa) is controversial. In this meta-analysis and systematic review, we investigated diabetes and time since diagnosis as risk factors for PCa. ...
Assessing SMC Complex Function in Replication Fork Progression with DNA Fiber Assays
Chromosome organization undergoes substantial changes during S phase, as parental strands unzip at replication forks to create sister chromatids. Structural Maintenance of Chromosomes (SMC) complexes actively organize ...
Biocontrol and ecophysiological characterization of bacterial and yeast BCA candidates isolated from two different environments to control postharvest diseases
Biocontrol agents are a sustainable alternative to chemical fungicides in postharvest protection. Part of their success depends on using strains able to persistently colonize the host and maintain a broad activity from the ...
Dysregulated autophagy in endometriosis: molecular mechanisms, controversies, and clinical implications
Endometriosis is one of the most common gynecological diseases in women and is still one of the most understudied diseases, affecting the daily lives of patients. Although the exact cause of this condition remains unclear, ...
