SMART: Unique splitting-while-merging framework for gene clustering
2014

Successful clustering algorithms are highly dependent on parameter settings. The clustering performance degrades significantly unless parameters are properly set, and yet, it is difficult to set these parameters a priori. To address this issue, in this paper, we propose a unique splitting-while-merging clustering framework, named "splitting merging awareness tactics" (SMART), which does not require any a priori knowledge of either the number …
Morphological Analysis Combined with a Machine Learning Approach to Detect Utrasound Median Sagittal Sections for the Nuchal Translucency Measurement
2017
The screening of chromosomal defects, as trisomy 13, 18 and 21, can be obtained by the measurement of the nuchal translucency thickness scanning during the end of the first trimester of pregnancy. This contribution proposes an automatic methodology to detect mid-sagittal sections to identify the correct measurement of nuchal translucency. Wavelet analysis and neural network classifiers are the main strategies of the proposed methodology to detect the frontal components of the skull and the choroid plexus with the support of radial symmetry analysis. Real clinical ultrasound images were adopted to measure the performance and the robustness of the methodology, thus it can be highlighted an er…
The problems and solutions to development of state mediation system: phenomenological aspects / Nacionalinės mediacijos sistemos kūrimo problemos ir …
2012
Research methods based on phenomenological approach in the field of management can help to create a meaningful theoretical framework and guidelines for the needs of improving the management. The article deals with the phenomenological approach in the context of the problem solving of institutionalization process of mediation. Although the work has presented the phenomenon of specific Latvian experience, the used methodology and the results are possible to use also for understanding and solving mediation system problems in other countries. Santrauka Vadovaujantis fenomenologiniu požiūriu pagrįstais tyrimais vadybos mokslo srityje, galima sukurti prasmingus teorinius principus ir nurodymus, r…
Theoretical study on the molecular mechanism of the [5 + 2] vs. [4 + 2] cyclization mediated by Lewis acid in the quinone system
2013
[EN] The thermal and Lewis acid (LA) catalyzed cyclizations of quinone 1 involved in the synthesis of Colombiasin A and Elipsaterosin B have been theoretically studied using DFT methods at the B3LYP/6-311G(d,p) computational level. B3LYP calculations suggest that the formal endo [4 + 2] cycloadduct allowing the synthesis of Colombiasin A is preferentially formed under thermal conditions, while in the presence of the BF3 LA catalyst the formal [5 + 2] cycloadduct is seen, allowing the synthesis of Elipsaterosin B. The BF3 LA catalyst not only accelerates the nucleophilic attack on the C2 carbon of the quinone framework through a more polar C-C bond formation, but also provokes a different el…
Understanding the regioselectivity in hetero Diels–Alder reactions. An ELF analysis of the reaction between nitrosoethylene and 1-vinylpyrrolidine
2013
[EN] The regioselectivity in the hetero Diels-Alder reaction between nitrosoethylene 1 and 1-vinylpyrrolidine 2 has been studied by a comparative ELF bonding analysis along the IRC of the endo/ortho and endo/meta regioisomeric channels at the B3LYP/6-31G*. level. Along the most favorable endo/ortho regioisomeric channel, the C-C sigma bond is first formed by coupling of two pseudoradical centers located at the most electrophilic carbon of 1 and the most nucleophilic center of 2. Formation of these relevant pseudoradical centers, which depend on the total charge transfer process along the polar reaction, and not on the approach mode of each reagent, is well characterized by analysis of the a…
Dorsal root ganglia neurite outgrowth measured as a function of changes in microelectrode array resistance
2017
Current research in prosthetic device design aims to mimic natural movements using a feedback system that connects to the patient's own nerves to control the device. The first step in using neurons to control motion is to make and maintain contact between neurons and the feedback sensors. Therefore, the goal of this project was to determine if changes in electrode resistance could be detected when a neuron extended a neurite to contact a sensor. Dorsal root ganglia (DRG) were harvested from chick embryos and cultured on a collagen-coated carbon nanotube microelectrode array for two days. The DRG were seeded along one side of the array so the processes extended across the array, contacting a…
Somatic experience of emotion in emotionally focused couple therapy: Experienced trainer therapists' views and experiences.
2021
In general, arousal of emotions is often felt and expressed as a somatic experience in the body. In Emotionally Focused Couple Therapy (EFT), the deepening of emotional experiencing enables therapeutic change. This research explores the experiences of eight experienced EFT trainer therapists regarding their somatic experiences in their work with couples. Using interpretative phenomenological analysis of transcribed in-depth interviews, this research data yielded three core themes that captured therapists' experiences of using their own and couples' somatic experiences in therapy: (1) the importance and relevance of somatic experiences, (2) therapists' use of their own somatic experiences, a…
Coseismic Damage at an Archaeological Site in Sicily, Italy: Evidence of Roman Age Earthquake Surface Faulting
2018
Archaeoseismology can provide a useful chronological tool for constraining earthquakes and documenting significant evidence that would otherwise be lost. In this paper, we report a case of surface faulting on ancient man-made structures belonging to the archaeological site of Santa Venera al Pozzo situated along the eastern flank of Mt. Etna volcano in eastern Sicily (southern Italy), which is affected by well-developed tectonic faults. Geological surveys highlight a set of fractures affecting the archaeological ruins, suggesting the occurrence of a capable fault zone across the area. An integrated geophysical survey was carried out in order to identify the main subsurface tectonic disconti…
Physiotherapists' lived experiences of decision making in therapeutic encounters with persons suffering from whiplash-associated disorder: A hermeneu…
2020
Conceptual discussions related to clinical reasoning and decision making have evolved over the years from biomedical to incorporating more holistic approach to reasoning. Empirical studies exploring clinical reasoning and decision making in physiotherapy practice have mostly focused on aspects of managing persons with low back pain, such as exercise prescription, education and communicating diagnosis. There is a paucity of studies exploring decision making in whiplash‐associated disorder (WAD); thus, the aim of this study was to explore the physiotherapists' lived experiences of decision making related to treating persons with WAD. A qualitative research design based on hermeneutic phenomen…
Hermeneutics and Phenomenology Problems When Applying Hermeneutic Phenomenological Method in Educational Qualitative Research
2020
Hermeneutic phenomenology is a research method used in qualitative research in the fields of education and other human sciences, for example nursing science. It is a widely used method example in Scandinavia, and Van Manen is well known for his hermeneutic phenomenological method. In many studies the hermeneutic phenomenological method is inarticulate or ambiguous. Researchers generally lack a common understanding of what this method actually is. One reason for that is that the expression “hermeneutic phenomenological method” is contradiction in terms. Hermeneutics and phenomenology have their own distinct history. Hermeneutics and phenomenology as philosophical disciplines have their own d…
