No full textlibnmxp e nmxptool: software Open-Source per trasmissioni dati sismici Nanometrics
No full textIl presente documento descrive le modalità di impiego della libreria software progettata dall’autore al
fine di implementare i protocolli di trasmissione Nanometrics. Lo sviluppo di tale libreria nasce
principalmente dall’esigenza all’interno dell’INGV di gestire un numero sempre più crescente di canali
sismici acquisiti tramite sistema Nanometrics. La libreria denominata libnmxp offre un insieme di API
(Application Program Interface) ben documentate che permettono di sviluppare software capace di interagire
con i due tipi di server Nanometrics:
• NaqsServer il quale implementa il protocollo per trasmissioni di dati in tempo reale;
• DataServer il quale implementa il protocollo per il recupero di dati archiviati.
Insieme alla libreria viene inoltre distribuito un programma chiamato nmxptool che basandosi su di
essa, permette di eseguire interrogazioni, ricevere dati in tempo reale e/o off-line, ed inoltre permette di
salvare questi ultimi in diversi formati, quali NMX e mini-SEED. Tale programma può inoltre essere
utilizzato come modulo per il sistema Earthworm o come plug-in per server SeedLink.
Uno dei principali contributi offerti da questo sviluppo consiste nella possibilità di gestire connessioni
di tipo Raw Stream con riordinamento dei pacchetti ritrasmessi: ciò permette di garantire un buon
compromesso fra la continuità del dato e una bassa latenza.
L’intero sviluppo si è basato sul manuale del corso Nanometrics [Nanometrics, Inc., 1989-2002], in
particolare su Nanometrics Data Formats, Reference Guide inclusa nella sezione Software Reference
Manuals.
La libreria libnmxp e il programma nmxptool sono scritti in linguaggio C e sviluppati usando i GNU
Build Tools (automake, autoconf, e script configure) tenendo in considerazione gli aspetti di compilazione
trasversale (cross-compilation) su tutte le piattaforme di tipo POSIX/UNIX. I sorgenti sono gratuiti e
possono essere modificati e ridistribuiti sotto i termini GNU Library General Public License, ulteriori

No full textCancer knocks you out by fasting: Cachexia as a consequence of metabolic alterations in cancer
No full textNeoplastic transformation reprograms tumor and surrounding host cell metabolism, increasing nutrient consumption and depletion in the tumor microenvironment. Tumors uptake nutrients from neighboring normal tissues or the bloodstream to meet energy and anabolic demands. Tumor-induced chronic inflammation, a high-energy process, also consumes nutrients to sustain its dysfunctional activities. These tumor-related metabolic and physiological changes, including chronic inflammation, negatively impact systemic metabolism and physiology. Furthermore, the adverse effects of antitumor therapy and tumor obstruction impair the endocrine, neural, and gastrointestinal systems, thereby confounding the systemic status of patients. These alterations result in decreased appetite, impaired nutrient absorption, inflammation, and shift from anabolic to catabolic metabolism. Consequently, cancer patients often suffer from malnutrition, which worsens prognosis and increases susceptibility to secondary adverse events. This review explores how neoplastic transformation affects tumor and microenvironment metabolism and inflammation, leading to poor prognosis, and discusses potential strategies and clinical interventions to improve patient outcomes
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
