Using of orientation senzor CHR6-DM in security technologies
No full textThis article presents the possibilities offered by exploiting CHR 6-DM Orientation Sensors in Security Technologies. It also addresses hardware resources suitable for the inertial navigation of RC models used in Security Technologies. The basis of the CHR 6-DM sensor is a gyroscope that is further complemented by an accelerometer and a magnetometer. In order to use orientation sensor security technology, suitable software was developed that can be used for the autonomous implementation of autonomous RC models suitable for use in Security Technology applications. © ECMS Thorsten Claus, Frank Herrmann, Michael Manitz, Oliver Rose (Editors)
PUMAS: a framework that adapts information in ubiquitous environments
No full textLos Dispositivos Móviles (DM) se caracterizan por sus intrínsecas capacidades reducidas (por
ejemplo, tamaño de la pantalla, memoria, capacidad de almacenamiento). PUMAS (Peer
Ubiquitous Multi-Agent System) es un framework basado en agentes cuyo principal objetivo es
proveer a usuarios nómadas con información adaptada a diferentes criterios (por ejemplo, sus
preferencias, localización, etc.) cuando acceden Sistemas de Información Web (SIW) a través de
sus DM. Los SIW pueden ejecutarse en uno o más servidores o, en uno o más DM. Los agentes de
PUMAS están organizados para llevar a cabo una búsqueda inteligente (basada tanto en el
conocimiento propio, adquirido e inferido de los agentes, como en su capacidad de razonamiento)
y, adaptativa (ya que toma en cuenta las características del usuario y las de su DM) de la
información que el usuario requiere proveniente de uno o más SIW. Cuando un usuario nómada
busca información a través de su DM, sus consultas se propagan a través de los agentes de
PUMAS (que adicionan a estas consultas algunas características del usuario y de su DM para ser
tenidas en cuenta al adaptar la información) hacia el Router Agent (del SMA de Información).
Dicho agente ejecuta el proceso de enrutamiento de consultas (Query Routing) que consiste en la
búsqueda de fuentes de información adecuadas que pueden responder las consultas del usuario
teniendo en cuenta las preferencias del usuario, las características de su DM, su localización, etc.
Esta búsqueda se basa en el conocimiento manejado e intercambiado por los agentes de PUMAS
(especialmente, aquellos pertenecientes a los SMA de Información y de Adaptación). Este artículo
presenta el conocimiento manejado e intercambiado por los agentes de PUMAS y la forma en que
se lleva a cabo el proceso de Query Routing en tres etapas: análisis de la consulta, envío de la
misma y recepción de sus resultados.Mobile Devices (DM) are characterized by their intrinsic reduced capacities (for
example, screen size, memory, storage capacity). COUGARS (Peer
Ubiquitous Multi-Agent System) is an agent-based framework whose main objective is
provide nomadic users with information adapted to different criteria (for example, their
preferences, location, etc.) when they access Web Information Systems (SIW) through
their DMs. SIWs can run on one or more servers, or on one or more DMs. Agents of
PUMAS are organized to carry out an intelligent search (based both on the
own, acquired and inferred knowledge of the agents, as in their reasoning capacity)
and, adaptive (since it takes into account the characteristics of the user and those of his DM) of the
information that the user requires from one or more SIWs. When a nomadic user
seeks information through his DM, his inquiries are propagated through the agents of
PUMAS (which add to these queries some characteristics of the user and his DM to be
taken into account when adapting the information) to the Router Agent (from the Information SMA).
Said agent executes the query routing process (Query Routing) which consists of the
search for suitable information sources that can answer user queries
taking into account the preferences of the user, the characteristics of his DM, his location, etc.
This search is based on the knowledge managed and exchanged by PUMAS agents
(especially those belonging to the Information and Adaptation SMA). This article
presents the knowledge managed and exchanged by PUMAS agents and the way in which
The Query Routing process is carried out in three stages: analysis of the query, sending the
itself and reception of its results
Síndrome de Adams-Oliver y complicaciones asociadas: reporte de una familia en Colombia y revisión de la literatura
No full textThe Adams-Oliver syndrome is a rare congenital disorder characterized by aplasia cutis congenita of the scalp, terminal transverse limb defects, and congenital telangiectatic cutis marmorata. It can occur through different inheritance patterns: autosomal dominant, autosomal recessive, or de novo dominant mutations.Although the Adams-Oliver syndrome is a rare disease, it is essential to know its clinical characteristics and inheritance patterns, to establish a correct diagnosis and its possible complications during follow-up.In the present study, we describe the case of an adolescent with Adams-Oliver syndrome with an autosomal dominant inheritance pattern, pulmonary hypertension and plastic bronchitis, and several compromised family members.El síndrome de Adams-Oliver es un trastorno congénito raro, caracterizado por aplasia cutis congénita en el cuero cabelludo, defectos terminales transversales de las extremidades y piel marmorata telangiectásica congénita. Este puede presentarse debido a diferentes patrones de herencia de tipo autosómico dominante o autosómico recesivo, o por mutaciones dominantes de novo.Aunque el síndrome de Adams-Oliver es una enfermedad poco frecuente, es importante conocer sus características clínicas y patrones de herencia, para así establecer un correcto diagnóstico y sus posibles complicaciones durante el seguimiento. En el presente estudio, se describe el caso de una adolescente con síndrome de Adams-Oliver con patrón de herencia autosómica dominante, hipertensión pulmonar y bronquitis plástica.

Radiomics-based analysis of contrast-enhanced and digital mammography for breast cancer classsification
No full textTreballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2025, Director: Oliver DíazContrast-Enhanced Spectral Mammography (CESM) is an advanced imaging modality that enhances breast cancer detection by combining conventional digital mammography (DM) with CESM obtained through intravenous contrast administration. This dual approach provides both morphological and functional information, improving lesion visibility,
particularly in patients with dense breast tissue. Radiomics, a rapidly evolving field in medical imaging, allows the extraction of high-dimensional quantitative features from medical images, capturing information about tumour phenotype, texture, and heterogeneity that may not be visually apparent.
This thesis investigates the application of radiomics analysis to CESM images with the aim of improving breast cancer classification. A key focus is on comparing the diagnostic performance of radiomics features derived separately from CESM and DM images, as well as evaluating the added value of combining both sets of features. Radiomics features are extracted and analysed using statistical and traditional machine learning techniques to
assess their effectiveness in distinguishing between benign and malignant lesions.
Furthermore, the study explores the development of predictive models based on these features and identifies the most relevant biomarkers for tumour classification. By systematically evaluating radiomics features derived from CESM, DM, and their combination, this research aims to determine the most effective imaging strategy for
accurate breast cancer classification. The findings may support more informed clinical decision-making and contribute to the advancement of personalized diagnostic approaches in breast cancer care.
Results show that models based on CESM images consistently outperformed those based on DM and combined data, confirming the hypothesis that contrast-enhanced imaging yields more informative radiomic features for tumour classification
The Effects of Consumer Cosmopolitanism on Purchase Behavior of Foreign vs. Domestic Products
No full textThe purpose of this empirical study is to investigate the effects of consumer cosmopolitanism on foreign product purchase behavior in three major categories of consumer products (alcohol products, clothes, furniture). Based on the existing theoretical and empirical knowledge, we develop a conceptual model and identify two additional constructs as antecedents of foreign purchase behavior, i. e., consumer ethnocentrism and consumer knowledge of brand origins. The measurement model is examined using a data set of 261 adult consumers and tested via structural equation modeling. The study results confirm the strong total effect of consumer cosmopolitanism in purchase behavior and indicate a strong direct effect of this phenomenon on the behavioral outcome. The more cosmopolitan consumers have a stronger tendency to buy foreign rather than local products. On the other hand, the direct relationship between cosmopolitanism and consumer knowledge of brand origin was not supported in the study.cosmopolitanism, consumer ethnocentrism, knowledge of brand origins, foreign product purchase behavior, Slovenia
Entanglement and quantity in quantum space - About quantum measurement (II)
No full textAs a continuation and extension of "quantity in phase space" "quantity in quantum space" is introduced. With that, the disappearing of quantum interference discussed in a previous paper [S. Durr, et al., Nature 395 (1998) 33] is explained in the same spirit as our recent papers [Ren De-Ming, Commun. Theor. Phys. (Beijing, China) 41 (2004) 685, 833].Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)1ARTICLE133-364
Sneutrino DM in the NMSSM with inverse seesaw mechanism
No full textIn supersymmetric theories like the Next-to-Minimal Supersymmetric Standard Model (NMSSM), the lightest neutralino with bino or singlino as its dominant component is customarily taken as dark matter (DM) candidate. Since light Higgsinos favored by naturalness can strength the couplings of the DM and thus enhance the DM-nucleon scattering rate, the tension between naturalness and DM direct detection results becomes more and more acute with the improved experimental sensitivity. In this work, we extend the NMSSM by inverse seesaw mechanism to generate neutrino mass, and show that in certain parameter space the lightest sneutrino may act as a viable DM candidate, i.e. it can annihilate by multi-channels to get correct relic density and meanwhile satisfy all experimental constraints. The most striking feature of the extension is that the DM-nucleon scattering rate can be naturally below its current experimental bounds regardless of the higgsino mass, and hence it alleviates the tension between naturalness and DM experiments. Other interesting features include that the Higgs phenomenology becomes much richer than that of the original NMSSM due to the relaxed constraints from DM physics and also due to the presence of extra neutrinos, and that the signatures of sparticles at colliders are quite different from those with neutralino as DM candidate.National Natural Science Foundation of China (NNSFC) [11575053]SCI(E)ARTICLE1
