Effect of age in the ciliary muscle during accommodation: Sectorial analysis
2017
Abstract Purpose To compare changes in the ciliary muscle area at different sectors between pre-presbyopic and presbyopic eyes during accommodation by means of an anterior segment optical coherence tomographer (OCT). Methods The anterior ciliary muscle area was measured in 20 healthy and phakic pre-presbyopic eyes, whose mean age was 23.3 ± 4.4 years, and in 20 healthy and phakic presbyopic eyes, whose mean age was 46.5 ± 5.2 years. The relative change in the cross-sectional area of the ciliary muscle was measured at the nasal, inferior, and temporal sectors between 0 and −3 D of vergence, in −1 D step. A linear model was used to assess the correlation of each eye parameter with the accommo…
Avaliação por OCT in vivo do comprimentos axiais centrais do segmento anterior
2017
ABSTRACT Purpose: To assess changes in anatomic structures in the anterior eye segment in terms of axial lengths with accommodation via optical coherence tomography. Methods: In this observational study, 25 eyes of 25 healthy adults were examined using the Visante® omni optical coherence tomography system. Central corneal thickness, anterior chamber depth, central lens thickness, and anterior segment length were assessed. The evaluated parameters were obtained with accommodation using different stimulus vergences, namely 0.0, -1.0, -2.0, and -3.0 D. Variation of these parameters was compared among different levels of accommodation. Results: Central corneal thickness was not altered at any s…
Massadatan käyttö asiakasanalytiikassa : case Jyväskylän Energia
2017
Massadata on suuresti puhuttava lisäarvon luomisen lähde niin tieteellisille yhteisöille kuin yrityksillekin. Massadatan käsite elää kehittyvän teknologian mukana, mutta tavallisimmillaan sitä voi kuvata suurena määränä dataa, joka on monimuotoista ja kasvaa suurella nopeudella. Massadata mahdollistaa paljon liiketoiminnassa hyödynnettävässä analytiikassa, kuten liiketoimintatiedon hallinnan ja analytiikan prosesseissa sekä asiakasanalytiikassa. Asiakasanalytiikassa massadata mahdollistaa syvällisemmän asiakasymmärryksen saavuttamisen datasta ja sen hyödyntämisen asiakassuhdehallinnasta aina merkityksellisemmän asiakassegmentoinnin tekemiseen. Tutkimuksessa käsitellään ensin massadataa sen …

Identifying relevant segments of AI applications adopters : Expanding the UTAUT2’s variables
2021
Artificial intelligence (AI) is a future-defining technology, and AI applications are becoming mainstream in the developed world. Many consumers are adopting and using AI-based apps, devices, and services in their everyday lives. However, research examining consumer behavior in using AI apps is scant. We examine critical factors in AI app adoption by extending and validating a well-established unified theory of adoption and use of technology, UTAUT2. We also explore the possibility of unobserved heterogeneity in consumers’ behavior, including potentially relevant segments of AI app adopters. To augment the knowledge of end users’ engagement and relevant segments, we have added two new antec…

Multilabel segmentation of cancer cell culture on vascular structures with deep neural networks
2020
New increasingly complex in vitro cancer cell models are being developed. These new models seem to represent the cell behavior in vivo more accurately and have better physiological relevance than prior models. An efficient testing method for selecting the most optimal drug treatment does not exist to date. One proposed solution to the problem involves isolation of cancer cells from the patients' cancer tissue, after which they are exposed to potential drugs alone or in combinations to find the most optimal medication. To achieve this goal, methods that can efficiently quantify and analyze changes in tested cell are needed. Our study aimed to detect and segment cells and structures from canc…
Smartphone Usage Among Millennial in Finland and Implications for Marketing Segmentation Strategies: Lessons for Nigeria
2018
The study examines smart phone usage by millennials based on different criteria of operating system, Wi-Fi, text messaging, internet surfing and social media. The study used quantitative methodology and data were gathered with online questionnaires with 391 young smartphone users in Finland. The Millennial were clustered into five levels. The results reveal the prominent status of profiling in a developed market and how marketers in emerging markets can apply segmentation and targeting strategies using instant messaging, text messages, email, mobile app, gamification and social media based on the profile of each segment. Nigerian policy makers should adopt a framework to make smartphone aff…
Modelling and prediction of perceptual segmentation
2017
While listening to music, we somehow make sense of a multiplicity of auditory events; for example, in popular music we are often able to recognize whether the current section is a verse or a chorus, and to identify the boundaries between these segments. This organization occurs at multiple levels, since we can discern motifs, phrases, sections and other groupings. In this work, we understand segment boundaries as instants of significant change. Several studies on music perception and cognition have strived to understand what types of changes are associated with perceptual structure. However, effects of musical training, possible differences between real-time and non real-time segmentation, and…
Prevención secundaria tras infarto agudo de miocardio con elevación del segmento ST: factores de riesgo y consecuencias clínicas de la falta de trata…
2018
INTRODUCCIÓN Las enfermedades cardiovasculares (ECV) son un conjunto de entidades patológicas que constituyen un serio problema de salud a nivel mundial por ser la primera causa de mortalidad. El síndrome coronario agudo es el responsable del mayor número de muertes, siendo el diagnóstico de infarto agudo de miocardio (IAM) el más frecuente. Todos los pacientes que han sufrido un IAM tipo 1 con elevación del segmento ST (IAMCEST) asociado a la presencia de aterosclerosis deben recibir tratamiento como prevención secundaria, salvo muy determinadas excepciones, con el objetivo de reducir la morbimortalidad asociadas. El tratamiento inicial tiene que ir dirigido a la reapertura urgente de la a…
