Brain tumor detection using fusion of hand crafted and deep learning features

The perilous disease in the worldwide now a days is brain tumor. Tumor affects the brain by damaging healthy tissues or intensifying intra cranial pressure. Hence, rapid growth in tumor cells may lead to death. Therefore, early brain tumor diagnosis is a more momentous task that can save patient from adverse effects. In the proposed work, the Grab cut method is applied for accurate segmentation of actual lesion symptoms while Transfer learning model visual geometry group (VGG-19) is fine-tuned to acquire the features which are then concatenated with hand crafted (shape and texture) features through serial based method. These features are optimized through entropy for accurate and fast classification and fused vector is supplied to classifiers. The presented model is tested on top medical image computing and computer-assisted intervention (MICCAI) challenge databases including multimodal brain tumor segmentation (BRATS) 2015, 2016, and 2017 respectively. The testing results with dice similarity coefficient (DSC) achieve 0.99 on BRATS 2015, 1.00 on BRATS 2015 and 0.99 on BRATS 2017 respectively.     

Goal projection in public places

Three studies investigated the phenomenon of goal projection in everyday life considering three moderators: goal commitment, the perceived similarity of the target person, and goal attainment. Moviegoers' (Study 1) highly committed to see a particular movie projected this goal onto other movie patrons. Commuters (Study 2) highly committed to catch a certain train projected this goal onto other commuters, given that these commuters were perceived as similar. Shoppers (Study 3) projected buying a particular item when both their goal commitment and the perceived similarity of another shopper were high, and the goal was not yet attained. The results imply that goal projection is part of our everyday life and is fostered by high‐goal commitment, perceiving others as similar, and ongoing goal striving.     

Novel fabrication of bulk Al with gradient grain size distributions via powder metallurgy

We describe a novel approach to synthesize gradient microstructures, defined hereafter as containing a broad but continuous distribution of grain sizes. These microstructures extend the concept of a bimodal grain size distribution and the ability to design with multiple length scales. We demonstrate the proposed approach via experiments involving cryogenic ball milling of Al–4.5Mg–0.4Mn–0.05Fe and Al–50Mg powder followed by subsequent consolidation. Our results reveal that the grains in the consolidated powder present a gradient size distribution ranging from <100 nm to >3 μm. Moreover, phase composition analysis revealed a unique “interfingered” structure where the two starting phases were intermixed in a complex three-dimensional mesh. Hardness studies of this gradient microstructure show average Vickers hardness values of 200 ± 2.6, 204 ± 4.3 and 266 ± 50 for macrohardness, microhardness and nanoindentation, respectively. The standard deviation values highlight that the gradient microstructure is disordered locally, but homogenous macroscopically.     

Winnicott's invitation to ‘further games of Jung‐analysis’

Winnicott signs off his celebrated review of Jung's (1963) autobiography Memories, Dreams, Reflections with the warning that translation of ‘erreichten’ as ‘attained’ (implying assimilation) rather than as ‘reached to’, could ‘queer the pitch for further games of Jung‐analysis’. This subtly underscores his view that Jung—who he described earlier as ‘mentally split’ and lacking ‘a self with which to know’—remained essentially dissociated. However, Winnicott, whilst immersed in this work on Jung, wrote a letter to Michael Fordham describing himself as suffering ‘a lifelong malady’ of ‘dissociation’. But this he now reported repaired through a ‘splitting headache’ dream of destruction, dreamt ‘for Jung, and for some of my patients, as well as for myself’ (Winnicott 1989, p. 228). Winnicott's recurrent concern during his last decade was with ‘reaching to’—that quintessential Winnicottian term—some reparative experience that could address such difficulties in constellating a ‘unit self’. This is correlated with his engagement with Jung and tracked through his contemporaneous clinical work, particularly ‘Fear of Breakdown’ (1963). Themes first introduced by Sedgwick (2008) and developed by the author's earlier ‘Winnicott on Jung; destruction, creativity and the unrepressed unconscious’ (2011) are given further consideration.     

Mind-reading in strategic interaction: The impact of perceived similarity on projection and stereotyping

In social dilemmas, negotiations, and other forms of strategic interaction, mind-reading—intuiting another party’s preferences and intentions—has an important impact on an actor’s own behavior. In this paper, we present a model of how perceivers shift between social projection (using one’s own mental states to intuit a counterpart’s mental states) and stereotyping (using general assumptions about a group to intuit a counterpart’s mental states). Study 1 extends prior work on perceptual dilemmas in arms races, examining Americans’ perceptions of Chinese attitudes toward military escalation. Study 2 adapts a prisoner’s dilemma, pairing participants with outgroup targets. Study 3 employs an ultimatum game, asking male and female participants to make judgments about opposite sex partners. Study 4 manipulates perceived similarity as well as counterpart stereotype in a principal–agent context. Across the studies, we find evidence for our central prediction: higher levels of perceived similarity are associated with increased projection and reduced stereotyping.     

Local supersaturation during melting in a temperature gradient

A homogeneous single-phase Al–Cu alloy was exposed to a steep temperature gradient for a short time interval, melting of the sample at the hot end was interrupted at intermediate stages. In the resolidified microstructure, the local supersaturation was determined by analysing concentration profiles across former liquid films at grain boundaries and adjacent zones in the grain interior. Already at moderate heating rates (3 K/s) significant supersaturations occurred and were quantified.     

Revealing texture architecture in a surface gradient nanostructured Al-Cu-Mg alloy

ABSTRACT

A multiscale crystallographic texture architecture in a surface gradient nanostructured Al-Cu-Mg alloy after surface sliding friction treatment (SSFT) has been revealed by a combination of electron backscatter diffraction and precession electron diffraction (PED)-assisted transmission electron microscopy (TEM) orientation mapping. Accompanying a grain structure variation from lamellar coarse grains to equiaxed nanograins, the major texture components evolve from brass {110}<112> in the coarse-grain matrix, Goss {110}<001> at a depth of ～80?μm, E {111}<011> and F {111}<112> at a depth of ～20?μm, to a mixture of rotated cube {001}<110>, E and F in the topmost surface layer. The through-thickness textural development and evolution are attributed to the cyclic loading of concurrent shear and compression during the SSFT processing. The PED-assisted orientation mapping shows good capability in mapping severe plastic-deformation-induced nanostructures with large residual strains and high defect density.     

New experimental test of strain-gradient plasticity theory: metal foil sandwich structures in flexure

Experimental tests of strain-gradient plasticity theory rely on studies of the size effect (smaller is stronger) in micromechanical testing. The plastic strain gradient is varied by varying the size of the specimen. This confounds the direct effects of the size and the effects of the strain gradient. We propose experiments on foil sandwich structures in which these parameters are separated. Preliminary results suggest that it is the foil thickness that determines the strength, not the strain gradient.     

Psychotherapy assessment: Theory and practice

The history and developments in psychotherapy assessment are reviewed. Suggestions for an extended assessment of several sessions derived from the clinical experience of a District Psychotherapy service are put forward with clinical illustrations. The advantages in terms of flexibility, and the ability to embrace the range of factors involved as well as the influence this has in generating a sense of containment in the patients, are discussed. The implications of this approach on technique, and its differentiation from ongoing psychotherapy, are highlighted. It is suggested that assessment should be seen as an entity in its own right, with its own clinical technique.
