Improving guest satisfaction by identifying hotel service micro-elements failures through Deep Learning of online reviews
Full text linkThis study thoroughly examines often-overlooked micro-service elements within the broader spectrum of hotel services, aiming to improve hospitality services and ensure guest satisfaction. To achieve this, this research developed a methodological framework, integrating (a) the VADER text sentiment analysis framework, (b) a robust logistic regression procedure to pinpoint specific hotel service components culprit for guest frustration, and (c) the application of semantic network analysis to yield guest insights contextualised within the realm of underperforming hotel service micro-elements. Research findings highlight fifty specific service micro-elements identified as triggers of negative sentiment and subsequent degrees of diminished guest satisfaction. Furthermore, this study zooms into the top ten underperforming service micro-elements by employing semantic network analysis to uncover the roots of typical guest frustrations with their hotel experiences. Though identified within hotel reviews, certain service malfunctions have relevance within the broader domain of destination management. The outcomes of this study suggest a valuable resource for managers in detecting and rectifying inadequately performing hotel service micro-elements, which are pivotal for elevating guest satisfaction within their respective hotel properties. Additionally, the findings provide impetus for hotel and destination managers to implement tailored strategies to increase guest satisfaction across hotels and destinations

Structural and compositional disturbance legacies mediate the resistance of European forests to repeated disturbances
Full text linkAim: Climate change is altering forest disturbance regimes across Europe. Structural and species diversity are generally thought
to enhance disturbance resistance. However, how disturbances affect stand structure and tree species diversity remains untested
across broad spatial gradients and for multiple disturbance agents. Furthermore, determining how disturbance-induced changes
affect resistance to subsequent disturbances is critical for understanding forest dynamics in the face of global change.
Location: The forests of Finland, France and Spain.
Time Period: 1986–2020ce.
Major Taxa Studied: Trees.
Methods: We examined the effects of tree size and tree species diversity on resistance to fire, wind, biotic and snow disturbances
using a National Forest Inventory dataset of 4827 disturbed plots. We quantified disturbance resistance as the tree mortality response to different severity disturbances. We modelled the immediate disturbance-driven changes in structural and tree species
diversity, and predicted how these changes affect resistance to subsequent disturbances.
Results: High structural diversity increased stand resistance to snow disturbance, and high species diversity decreased resistance to fire. Severe disturbances consistently decreased structural and species diversity across all disturbance agents. However,
both diversity metrics increased after low severity snow disturbances, and structural diversity increased after low severity
biotic disturbance. Resistance to subsequent disturbance increased after low severity fire and low to moderate severity wind disturbances. Biotic and snow disturbance had the opposite effect, with moderate severity disturbances decreasing resistance to
subsequent disturbance more than low severity disturbances.
Main Conclusions: Structural and species diversity had little effect on plot-level disturbance resistance. Severe disturbances
consistently decreased structural and species diversity, while low to moderate severity disturbances can increase these diversities. Resistance to subsequent disturbance is contrasted between disturbance agents and disturbance severity. Increasing disturbance severity may decrease structural and species diversity in future forests.Agence Nationale de la RechercheResearch Council of FinlandBundesministerium für Bildung und ForschungComisión EuropeaAgencia Estatal de InvestigaciónOrganismo Autónomo Parques Nacionale
Emergence and spatiotemporal incidence of dengue in Rio Grande do Sul, Brazil
Full text linkThis ecological study used surveillance data to examine the spatiotemporal dynamics of dengue in RS from 2007 to 2023. The temporal progression and geographic distribution of the cases were analyzed using generalized additive models (GAM), Local Indicators of Spatial Association (LISA), and spatiotemporal scan statistics. During the study period, 126,067 dengue cases and 142 deaths were reported, with 80.5% of cases and 85.2% of deaths occurring between 2022 and 2023. The mean incidence rate was 65.3 per 100,000 inhabitants, and the mortality rate was 0.11 per 100,000. The GAM analysis demonstrated a marked escalation in dengue risk beginning in 2019, with pronounced intensification from 2022 onward, indicating an ongoing epidemic. Most cases and fatalities were concentrated in the Northwest Rio Grande and Metropolitan Porto Alegre mesoregions. Significant spatial clusters were detected in the Central Eastern Rio Grande and Central Western Rio Grande mesoregions between 2021 and 2023, encompassing approximately 2.8 million individuals. These findings underscore the critical need to enhance surveillance and implement robust primary-prevention measures. Such measures are vital for curbing the current epidemic and mitigating the risk of future outbreaks. This study provides a detailed epidemiological assessment of dengue expansion in RS, highlighting priority areas for intervention and resource distribution to effectively manage evolving public health threats

Los topónimos Nonasp(e) y Nambroca: difíciles, distantes y distintos
No full textEn aquest treball examinem la connexió d'apos;un dels topònims de la Franja, Nonasp, amb el toledà Nambroca, apuntada per Coromines a l'OnCat (v, 473a16) en una mostra de visió hispànica global. A partir de l'anàlisi del topònim toledà es comprova, tanmateix, que no hi ha raó per vincular els dos noms de lloc i que per a Nonasp es pot entreveure una via d'estudi alternativa, diferent de les ofertes fins ara.In this paper we examine the connection of one of the place names of the "Franja", Nonasp(e), with Nambroca in Toledo, noted by Coromines at OnCat (v, 473a16) in a example of global Hispanic vision. From the analysis of the Toledan place name, it is verified, however, that there is no reason to link both place names and that for Nonasp(e) an alternative path of study can be envisioned, different from those offered so far.Agencia Estatal de Investigación (AEI
Self-referenced carrier frequency offset interferogram correction for distributed sensing using dual-comb systems
Full text link29Th. International Conference on Optical Fiber SensorsDual optical frequency comb (DOFC) has been unveiled as a prevailing tool for an increasing range of applications, such as molecular spectroscopy, ranging, imaging, and distributed sensing. Maintaining a high degree of temporal stability between the two mutually coherent interfering combs composing the DOFC is essential in emerging applications such as ranging and distributed sensing, where the amplitude and/or the phase profiles of subsequent interferograms are compared to extract time-varying information. In this work, we present a simple and efficient self-referencing correcting technique aimed at estimating and compensating for carrier frequency offset of time-domain interferograms. We validate our algorithm through a proof-of-concept spectroscopy experiment based on DOFC generated using optically injected gainswitched semiconductor lasers. Our experiments validate proper interferogram alignment with an SNR improvement of 38 dB along an interrogation time of nearly 0.2 s
Writing as an exercise in resistance : the books of Antonio Fernández Alba
Full text linkEl texto analiza la escritura de Antonio Fernández Alba como un doble acto de resistencia: contra el olvido y contra la banalización del discurso arquitectónico. Sus libros se constituyen en espacio proyectual paralelo a su obra. El artículo presenta el libro como dispositivo crítico que integra palabra, imagen y dibujo para construir sentido.
Con el apoyo de la hermenéutica de Paul Ricoeur y la crítica cultural de Walter Benjamin como marco teórico, se entiende la narración y la arquitectura como mediaciones frente a la lógica instrumental moderna. La revisión de la producción editorial del autor se articula desde el análisis histórico y hermenéutico junto a referencias sobre narratividad y cultura arquitectónica.
Todo ello arroja la conclusión de que los libros de Fernández Alba no son meros contenedores de textos, sino dispositivos que organizan y construyen pensamiento, proyectando nuevas interpretaciones en cada relectura. Esta relación entre proyecto arquitectónico y editorial permite una herramienta crítica aplicable a la práctica contemporánea.The text examines Antonio Fernández Alba’s writing as a dual act of resistance: against oblivion and against the trivialization of architectural discourse. His books constitute a parallel projective space to his built work. The article presents the book as a critical device that integrates word, image, and drawing to construct meaning.
Grounded in Paul Ricoeur’s hermeneutics and Walter Benjamin’s cultural critique as its theoretical framework, narrativity and architecture are understood as mediations that counter the instrumental logic of modernity. The review of the author’s editorial production is articulated through historical and hermeneutic analysis, combined with references to narrativity and architectural culture.
This approach leads to the conclusion that Fernández Alba’s books are not mere containers of texts but devices that organize and construct thought, projecting new interpretations with each rereading. The relationship between architectural and editorial projects thus emerges as a critical tool applicable to contemporary practice
Multi-interest dual-adaptive unscented Kalman Filter with online parameter optimization for nonlinear battery modeling
No full textReliable driving range prediction is a key requirement for modern electric mobility. However, it remains challenging due to the complex electrochemical dynamics of lithium-ion batteries and their sensitivity to varying operating conditions. To address these challenges, this study proposes a novel framework integrating an enhanced second-order RC equivalent circuit model with a multi-criterion adaptive Unscented Kalman Filter algorithm (i-DAUKF) for improved state estimation accuracy. Firstly, the enhanced RC model is developed to optimize the battery parameter selection using a moving window average algorithm, while incorporating online parameter optimization to dynamically update measurement and predictive coefficients. The i-DAUKF algorithm is designed to better capture nonlinear battery behavior under operational thermal fluctuations and degradation processes, ensuring robust estimation fidelity across diverse operating conditions. Unlike conventional filtering approaches that rely on static tuning, the proposed method continuously refines model parameters, significantly improving adaptability and robustness. The novel contributions include: (i) integration of a refined second-order RC model with adaptive parameter calibration, (ii) dynamic optimization of predictive and measurement gains for sustained stability, and (iii) demonstration of application-specific improvements across transient and steady-state phases. Simulation results validate the effectiveness of the framework, achieving SOC estimation errors of 0.043 and 0.714% (RMSE), and voltage errors of 0.320 and 1.42% (RMSE), respectively. Comparative evaluations further reveal that i-DAUKF consistently achieves the lowest estimation errors (SOC RMSE <2,5%, voltage 1%?3%) with negligible computational cost, thereby establishing its superiority in accuracy, robustness, and real-time efficiency for nonlinear battery modeling under dynamic driving conditions.European UnionMinisterio de Ciencia, Innovación y UniversidadesComunidad de Madri
Caracterización de la respuesta inmune de células B en respuesta a la inmunización con la proteína mALDH4A1
No full text10 p.Las enfermedades cardiovasculares son la principal causa de mortalidad a nivel mundial, siendo la mayoría
de estas muertes provocadas por el infarto de miocardio o el accidente cerebrovascular. El principal
determinante subyacente de los eventos cardiovasculares es la aterosclerosis. En el laboratorio receptor
recientemente se identificó la proteína mitocondrial ALDH4A1 como un antígeno de esta enfermedad y se
mostró que la inmunización pasiva con un anticuerpo anti-ALDH4A1 era ateroprotectora. Para valorar la
posibilidad de usar estrategias de inmunización activa con ALDH4A1, en este trabajo se inmunizaron
ratones con 1 o 2 dosis de la proteína recombinante mALDH4A1 y se caracterizó la respuesta humoral. Se
emplearon ratones portadores de la construcción génica Aicda-Cre ERT2ki/+ k-Tagki/+
, que permite trazar
células B activadas y los anticuerpos que producen. Se demostró que la inmunización induce la activación
y expansión de células B de centro germinal y plasmáticas (PC) en bazo y la generación de PCs de larga
vida en médula ósea. Además, hemos encontrado que una única dosis de inmunización da lugar a
anticuerpos dirigidos contra la región C-terminal de la proteína, mientras que tras la segunda dosis de
inmunización la especificidad se dirige hace la región N-terminal, proceso que se denomina
enmascaramiento de epítopos. Estos resultados demuestran que la inmunización con ALDH4A1 produce
una respuesta inmune humoral canónica eficiente y que conlleva enmascaramiento de epítopos,
mecanismo que juega un papel fundamental en el diseño de estrategias de vacunación.Máster Universitario en Dianas Terapéuticas en Señalización Celular: Investigación y Desarrollo (M132
