UV Photofunctionalization Effect on Bone Graft in Critical One-Wall Defect around Implant: A Pilot Study in Beagle Dogs

The purpose of this study was to compare and evaluate, through histomorphometric and radiological analysis, the effects of UV photofunctionalization on an implant placed over a critical defect area with and without a bone graft. Four female beagle dogs were first divided into control and bone graft groups. Each group was then subdivided into UV-treated and UV-untreated groups. The mandibular premolars in each dog were extracted. 12 weeks after extraction, implants were placed according to the condition of each group. Four and 12 weeks after implantation on left and right mandible, the dogs were sacrificed. The specimens were prepared for histomorphometric and micro-computed tomographic analysis. In both 4-week and 12-week groups, UV-treated implant surfaces showed better osseointegration than SA implant surfaces. Also, with implant surfaces placed over the critical defect with bone graft, UV photofunctionalization increased bone-to-implant contact (BIC) and new bone formation at the initial stage (4 weeks). Based on the results of this study, it can be suggested that UV photofunctionalization on the surface of implants placed over large critical defects with bone graft aids initial osseointegration and osteogenesis.
Analysis of Photo Sharing and Visual Social Relationships: Instagram as a case study

This article discusses how visuality, through the mobility of Instagram, modifies individuals’ mediated lives. In particular, it examines how Instagram transforms individuals’ perceptions of their interpersonal relationships. It advances a critical re-reading of the concept of mobility (smart mobile devices) and the new approach to sociality. Conducting an empirical examination, this article delineates the changing dynamics that digitality determines within contemporary life experiences. Findings show that the ubiquitous use of smart mobile devices leads individuals towards the development of new forms and conceptions of mobile mediated visualities. In order to understand the rise of new visual practices based on Pink’s ethnographic work, this article considers how relationships develop among individuals, visual technologies, practices and images, society and culture. A qualitative approach informed by netnography, computer-mediated interviews and visual analysis is employed in this study. The critical analysis of 44 participant interviews and their photo sharing behaviour presents the transformations that the mediation and mobility of Instagram bring into everyday relations between humans and technologies. The increased use of social media shows how sociality is affected and mediated by new mobile technologies. Although the social potentiality of (visual) social relationships itself does not offer a variety of verbal communication mechanisms, it encourages offline meetings or the relocation onto other social media. This shows that every alteration in the structure of societies has influence on individuals and on their means of expression.
Blurry-ORAM: A Multi-Client Oblivious Storage Architecture

Since the development of tree-based Oblivious RAM by Shi et al. (Asiacrypt ’11) it has become apparent that privacy preserving outsourced storage can be practical. Although most current constructions follow a client-server model, in many applications it is desirable to share data between different clients, in a way that hides the access patterns, not only from the server, but also between the clients. In this work, we introduce BlurryORAM, an extension of Path-ORAM that allows for oblivious sharing of data in the multi-client setting, so that accesses can be hidden from the server and other clients. Our construction follows the design of Path-ORAM as closely as possible in order to benefit from its performance as well as security. We prove our construction secure in a setting where the clients are semi-honest, do not trust each other but try to learn the access patterns of each other.
Differential Notch and TGFβ Signaling in Primary Colorectal Tumors and Their Corresponding Metastases

Background: Loss of epithelial morphology and the acquisition of mesenchymal characteristics may contribute to metastasis formation during colorectal tumorigenesis. The Wnt, Notch and TGFβ signaling pathways control tissue homeostasis and tumor development in the gut. The relationship between the activity of these pathways and the expression of epithelial and mesenchymal markers was investigated in a series of primary colorectal tumors and their corresponding metastases. Methods: Tissue samples of primary colorectal tumors, normal colonic mucosa, and regional and systemic metastases were processed for immunohistochemistry in a tissue microarray format. The expression of mesenchymal (vimentin, fibronectin) and epithelial (E-cadherin) markers was related to markers of Wnt (β-catenin), Notch (HES1) and TGFβ (phospho-SMAD2) signalling. In addition, the KRAS mutation status was assessed. Results: When compared to normal mucosa, primary colorectal tumors showed a marked increase in the levels of cytoplasmic vimentin and nuclear β-catenin, phospho-SMAD2 and HES1. Increased vimentin expression correlated with the presence of oncogenic KRAS and with nuclear β-catenin. The corresponding liver, lymph node, brain and lung metastases did not express vimentin and displayed significantly lower levels of nuclear phospho-SMAD2 and HES1, while retaining nuclear β-catenin. Conclusions: Primary colorectal carcinomas display aberrant expression of vimentin, and have activated Notch and TGFβ signaling pathways. Surprisingly, many regional and distant metastases have lost nuclear HES1 and pSMAD2, suggesting that the activity of the Notch and TGFβ pathways is reduced in secondary colorectal tumors.
"Picture the scene...";: Visually Summarising Social Media Events

Due to the advent of social media and web 2.0, we are faced with a deluge of information; recently, research efforts have focused on filtering out noisy, irrelevant information items from social media streams and in particular have attempted to automatically identify and summarise events. However, due to the heterogeneous nature of such social media streams, these efforts have not reached fruition. In this paper, we investigate how images can be used as a source for summarising events. Existing approaches have considered only textual summaries which are often poorly written, in a different language and slow to digest. Alternatively, images are "worth 1,000 words" and are able to quickly and easily convey an idea or scene. Since images in social media can also be noisy, irrelevant and repetitive, we propose new techniques for their automatic selection, ranking and presentation. We evaluate our approach on a recently created social media event data set containing 365k tweets and 50 events, for which we extend by collecting 625k related images. By conducting two crowdsourced evaluations, we firstly show how our approach overcomes the problems of automatically collecting relevant and diverse images from noisy microblog data, before highlighting the advantages of multimedia summarisation over text based approaches.
Application of the check-all-that-apply method (CATA) to get insights on children's drivers of liking of fiber-enriched apple purees

Developing food products for children requires their involvement since their needs differ from those of adults. Descriptive methods are helpful in defining product's sensory properties that drive consumer's liking but they are not recommended with children. Consequently, finding new approaches to develop food tailored for children is one of the biggest challenges for food companies and sensory and consumer research scientists. This study has a twofold aim: (a) to test the suitability of check-all-that-apply (CATA) questions to obtain a sensory description of fiber-enriched apple purees by children; (b) to investigate the drivers of liking of these products. Sixty-two children (8–11 years) evaluated the overall liking of six apple purees varying in appearance and texture and answered a series of CATA questions. Results showed that children were able to generate appropriate descriptive terms and to discriminate the samples according to the a priori modified sensory modalities using the CATA method. Sweet taste and a uniform texture (sandy, doughy, and floury attributes) were positive predictors of apple purees children liking, whereas sour taste, granular and crunchy texture were negative predictors. Practical applications The check-all-that-apply (CATA) method is an appropriate, child-friendly approach to get insights on how young consumers perceive a food product and identify the most relevant sensory attributes that affect children's hedonic perception. The use of CATA technique could be useful for food products research and development to understand children's drivers of liking and to obtain effective input for products optimization that meet children's sensory expectation, assuring product's success with this specific target of consumers.
A Motivational Perspective on Mass Communication Students’ Satisfaction With Their Major: Investigating Antecedents and Consequences

This study used self-determination theory (SDT) to investigate the motivations for selecting a major among mass communication and media majors at 18 colleges and universities across the United States. Specifically, 669 mass communication majors were queried on their intrinsic and extrinsic motivations for choosing a major, their degree of major satisfaction, and positive outcomes related to academic performance and overall well-being. As a whole, the findings suggest that students who select their major on the basis of its perceived ability to satisfy intrinsic needs tend to be more satisfied with their major selection and report higher levels of academic performance, career surety, and overall life satisfaction. These results are discussed in the context of both post-secondary mass communication programs and students’ ability to successfully navigate the transition into professional life.
Arabic Morphology in the Neural Language System

There are two views about morphology, the aspect of language concerned with the internal structure of words. One view holds that morphology is a domain of knowledge with a specific type of neurocognitive representation supported by specific brain mechanisms lateralized to left fronto-temporal cortex. The alternate view characterizes morphological effects as being a by-product of the correlation between form and meaning and where no brain area is predicted to subserve morphological processing per se. Here we provided evidence from Arabic that morphemes do have specific memory traces, which differ as a function of their functional properties. In an MMN study, we showed that the abstract consonantal root, which conveys semantic meaning (similarly to monomorphemic content words in English), elicits an MMN starting from 160 msec after the deviation point, whereas the abstract vocalic word pattern, which plays a range of grammatical roles, elicits an MMN response starting from 250 msec after the deviation point. Topographically, the root MMN has a symmetric fronto-central distribution, whereas the word pattern MMN lateralizes significantly to the left, indicating stronger involvement of left peri-sylvian areas. In languages with rich morphologies, morphemic processing seems to be supported by distinct neural networks, thereby providing evidence for a specific neuronal basis for morphology as part of the cerebral language machinery.
WEARPG: game design implications for movement-based play in table-top role-playing games with arm-worn devices

Combining the physical and the digital is one of the most trending topics in game research in HCI. Augmenting the table-top role-playing games (TTRPG) by adding electronic devices is a growing research area, yet the introduction of new play styles is still open for exploration. We believe that integration of wearable devices and movement-based play, which are also prominent research areas for gaming, hold potential for increasing the TTRPG experience since these are observed to increase the connectedness of players to imaginary world of games by previous studies. However, such augmentation will also bring changes in game design and these changes were not investigated thorougly in previous studies. To understand how game design of such games may change due to the usage of wearables and movement-based play, we conducted a participatory design workshop with (1) 25 participants, (2) designed a new game system according to our findings and (3) evaluated it with iterative tests with 15 participants in TTRPG sessions. Our study resulted in 8 player-centered game design implications for the use of arm-worn devices and movment-based play in narrative based long-term games like TTRPG. The implications present clues about forming the narrative, regulating the rules and the functional use of the device in game mechanics.
Estimating IBNR Claims Reserves for General Insurance Using Archimedean Copulas

Claims reserving for general insurance business has developed significantly over the recent past. There has always been a slight mystery in short-term insurance contracts of how to go about reserving for claims, which have not yet come in, and are still in some sense of figment of the future. Insurance claims variables are non-normally distributed and therefore a measure that will capture the dependence among the variables better than the usual correlation is employed. One such method is the use of copulas. The object of this paper, therefore, is to use the Archimedean copula, Clayton copula and Frank copula to estimate outstanding incurred but not reported (IBNR) claim reserves. A comparison of the estimates of outstanding claim reserves obtained from different Archimedean copulas is also presented.
Two-Cell MISO Interfering Broadcast Channel with Limited Feedback: Adaptive Feedback Strategy and Multiplexing Gains

In this paper, we study a two cell multiple input single-output interfering broadcast channel with finite rate feedback. In this system, we first derive the rate loss due to the quantization error by considering a coordinated zero-forcing beamforming. In addition, feedback bits allocation methods are proposed to minimize the performance degradation caused by the quantization error. Lastly, we investigate how many feedback bits per user are necessary to maintain the optimal multiplexing gain in MISO-IFBC. Through numerical evaluations, we show that our proposed feedback bits allocation strategy provides significant gain compared to a trivial bits allocation scheme.
Odonatan Endophytic Oviposition from the Eocene of Patagonia: The Ichnogenus Paleoovoidus and Implications for Behavioral Stasis

Abstract We document evidence of endophytic oviposition on fossil compression/impression leaves from the early Eocene Laguna del Hunco and middle Eocene Río Pichileufú floras of Patagonia, Argentina. Based on distinctive morphologies and damage patterns of elongate, ovoid, lens-, or teardrop-shaped scars in the leaves, we assign this insect damage to the ichnogenus Paleoovoidus, consisting of an existing ichnospecies, P. rectus, and two new ichnospecies, P. arcuatum and P. bifurcatus. In P. rectus, the scars are characteristically arranged in linear rows along the midvein; in P. bifurcatus, scars are distributed in double rows along the midvein and parallel to secondary veins; and in P. arcuatum, scars are deployed in rectilinear and arcuate rows. In some cases, the narrow, angulate end of individual scars bear a darkened region encompassing a circular hole or similar feature indicating ovipositor tissue penetration. A comparison to the structure and surface pattern of modern ovipositional damage on dicotyledonous leaves suggests considerable similarity to certain zygopteran Odonata. Specifically, members of the Lestidae probably produced P. rectus and P. bifurcatus, whereas species of Coenagrionidae were responsible for P. arcuatum. Both Patagonian localities represent an elevated diversity of potential fern, gymnosperm, and especially angiosperm hosts, the targets of all observed oviposition. However, we did not detect targeting of particular plant families. Our results indicate behavioral stasis for the three ovipositional patterns for at least 50 million years. Nevertheless, synonymy of these oviposition patterns with mid-Mesozoic ichnospecies indicates older origins for these distinctive modes of oviposition.
Experimental rat model for alcohol-induced osteonecrosis of the femoral head

Alcohol‐induced osteonecrosis of the femoral head (ONFH) is observed in alcohol abusers and patients with alcoholic fatty liver disease. It has been reported that Toll‐like receptor 4 (TLR4) signalling plays a crucial role in the pathogenesis of alcoholic fatty liver disease. We previously reported a corticosteroid‐induced ONFH rat model, and suggested that TLR4 signalling contributes to the pathogenesis of ONFH. Thus, it is thought that the pathogenesis of alcohol‐induced ONFH is probably similar to that of corticosteroid‐induced ONFH. The aim of this study was to develop a new animal model for alcohol‐induced ONFH and to evaluate the relationship between the pro‐inflammatory response via TLRs and the development of ONFH in rats. Male Wistar rats were fed a Lieber–DeCarli liquid diet containing 5% ethanol (experimental group) or dextran (control group) for 1–24 weeks. Histopathological and biochemical analyses were performed. Feeding the ethanol‐containing liquid diet resulted in the development of ONFH with hepatic steatosis, hepatic dysfunction and hyperlipidaemia, whereas feeding the dextran‐containing diet did not cause ONFH. However, we could not recognize any relationship between the pro‐inflammatory response via TLR4 and the development of alcohol‐induced ONFH. Thus in this study we have developed a new rat model for alcohol‐induced ONFH based on the feeding of an ethanol liquid diet. ONFH was observed within seven days from the start of feeding with 5% ethanol‐containing liquid diet. Although this was linked to hepatic steatosis, a TLR4 association was not a feature of this model.
Competitive status influences tree‐growth responses to elevated CO2 and O3 in aggrading aspen stands

1. Competition effects on growth of individual trees were examined for 4 years in aggrading, mixed-clone stands of trembling aspen (Populus tremuloides Michx.) at the Aspen-FACE free-air Co2 and O3 enrichment facility in northern Wisconsin, USA. During each growing season stands received one of four combinations of atmospheric [CO2] (ambient vs~56 Pa) and [O3] (ambient vs~1.5 x ambient). 2. Non-destructive measurements of annual tree growth were compared within and among clones and treatments in relation to an index of competitive status based on the difference between a tree's height and that of its four nearest neighbours. Competitive status strongly influenced tree growth, and the positive growth response to elevated [CO2] was greater for competitively advantaged individuals than for disadvantaged individuals of most clones. 3. The magnitude of O3 effects on growth depended on clone and competitive status: for some clones, negative O3 effects were stronger with competitive advantage while others showed stronger O3 effects with competitive disadvantage. The interactive effects of CO2 and O3 differed among clones, with negative effects of O3 amplified or ameliorated by elevated CO2, depending on clone and competitive status. 4. Treatments modified competitive interactions by affecting the magnitude of growth differences among clones. These modifications did not alter clone rankings of competitive performance, but when CO2 and 03 were both elevated, the differences in competitive performance among clones decreased.
Promoting student teachers’ adaptive capabilities through community engagement

The gap between student teachers and their ability to adapt to the school situation remains a challenge. The literature further indicates that there is an under-utilisation of students' abilities in an ever-changing curriculum that should be responsive to the challenges with which communities are faced. This paper aims to report on the students' adaptive capabilities through a school-initiated community engagement project. Approximately nine students were placed at schools on Saturdays while offering lessons to grade nine learners. A focus group interview was held with the students who offered natural sciences, mathematics and social sciences after the initiative. Findings of this study included raising the students' awareness for the need and ability to improvise in order to attend to the needs of the school and their ability to go out and seek information from other schools, the university and experienced teachers. The students were also able to leave the handouts they had designed for the school. The study provides insights into the adaptability of students in schools and recommends further empowerment spaces for student teachers and the school community.
Histological Diagnosis and Frequency of Primary Endocrine Tumors (ETs) and Neuroendocrine Tumors (NETs) According to WHO Classification

he new WHO classification provides the foundation for tumor diagnosis, patient treatment and tools for clinicoepidemiological research. This study was conducted to determine the frequency and update the histological aspects of different endocrine and neuroenodocrine tumors for clinical significance and to minimize unclassified lesions. Materials and Methods: Five hundred biopsies were analyzed in the Pathology Department of King Edward Medical University from 1st June 2004 to 31st December 2005. Tumors were diagnosed with light microscopy using the new WHO classification. Results: Following 500 biopsies, 145 (29%) Endocrine(ET) and Neuroendocrine Tumors (NET) were found; majority of the former, ET, n=112 (77.2%), were in the thyroid, of which 84 (75%) were follicular adenomas and 28 (25%) were carcinomas, of the 28 carcinomas, the frequencies were: papillary carcinoma (PC) 21 (75%); anaplastic(AC) 4 (14.28%); follicular(FC) 2 (7.14%); and medullary (MC) 1 (3.57%). Of the 145, 33 (22.8%) were neuroendocrine tumors (NET), with the following types and frequencies: adrenal 13 (39.5%); pituitary 10 (30.5%); pancreatic 4 (12%); parathyroid 3(9%); appendix 1 (3%); and rectum 1 (3%). One NET detected in the thyroid region was a well-differentiated neuroendocrine carcinoma (WDNEC). Among adrenal NETs, of 13 only 2 (14.4%) were malignant and diagnosed as a cortical and a neuroblastoma respectively, while all others were benign NETS, as follows: cortical adenoma 2 (15.38%); pheochromocytoma 7 (53.8%) and 1 (7.69%) ganglio neuroblastoma, and ganglioneuroma each respectively. All pituitary, parathyroid and pancreatic NETS were benign in nature. NETS of the appendix and rectum were WDNETS, while that of the lung was a WDNEC. Findings of this study confirm that the WHO classification provides uniform, simple, reproducible and practical criteria for diagnosis of ETs and NETS.
