Robust Dynamic Trajectory Regression on Road Networks: A Multi-task Learning Framework

Trajectory regression, which aims to predict the travel time of arbitrary trajectories on road networks, attracts significant attention in various applications of traffic systems these years. In this paper, we tackle this problem with a multitask learning (MTL) framework. To take the temporal nature of the problem into consideration, we divide the regression problem into a set of sub-tasks of distinct time periods, then the problem can be treated in a multi-task learning framework. Further, we propose a novel regularization term in which we exploit the block sparse structure to augment the robustness of the model. In addition, we incorporate the spatial smoothness over road links and thus achieve a spatial-temporal framework. An accelerated proximal algorithm is adopted to solve the convex but non-smooth problem, which will converge to the global optimum. Experiments on both synthetic and real data sets demonstrate the effectiveness of the proposed method.
Eye-tracking on smartphones using regression-based prediction

In this paper, we propose a regression-based prediction algorithm that can be used in eye-tracking and/or blinking detection systems on smartphones with accelerometers. We use linear regression as an instrument to calibrate accelerometers in our eye-location prediction algorithm. Eye-tracking and/or blinking detection algorithms have various applications in mobile environments. For example, to mitigate Computer Vision Syndrome (CVS) from which many smartphone users suffer, eye blinking detection systems running on smartphones can give advices to users regarding their eye blinking habits. Experimental results on real smartphones show that our regression based prediction shows around 30 percent points improvement over a naïve implementation of an existing solution.
Students with disability, the disability unit and lecturers' narratives of disability within a tertiary institution.

The purpose of the study was to explore the narratives of disability among students with disabilities, lecturers and the Disability Unit (DU) within a tertiary institution with a view to better understand their experiences and required initiatives to address the challenges of disability within a tertiary institution. Understanding how students with disabilities within a higher education context perceive and experience disability as well as how key players, namely lecturers’ and DU staff, who influence that experience is important in providing a truly inclusive environment for all within a tertiary institution. A review of the literature highlights that despite enabling legislation, in many South African Higher Education Institutions students with disability still experience many barriers to learning. The study drew from three theoretical frameworks in understanding participants’ narratives, namely social constructionism, feminist disability theory and a Foucauldian perspective. A qualitative study was conducted among 24 participants, who were purposively sampled and consisted of students with disability (N=12), disability unit staff members (N=7) and lecturers (N=5) within a South African tertiary institution. Semistructured interviews and biographical questionnaires were used to collect the data which was analysed using thematic analysis. The findings indicate that dominant representations of disability that exist within the tertiary context are disempowering and understand different embodiment, as less. There is a strong emphasis on students having to adapt in a tertiary context. Through normalisation mechanisms of the ‘gaze’, through engagement with the nondisabled and through the language used when speaking about students with disability, dominant understandings are perpetuated and internalised. Consequently, many students with disability modify their behaviour and act in ways to fit in and disassociate with being disabled. Further, many believe that they have to take ownership for their disability and manage it. These
Aerial virtual reality 360 research-creation

This paper presents a development of an aerial virtual reality 360 video capture approach. A drone was converted and retrofitted with a 360 spherical panorama camera for acquiring source aerial visual content. In this case study, an experiment of a 360-fly-by video was reproduced for the intended use of an event launching where user perception was being observed in terms of practicality and suitability. Utilizing a consumer 360 camera the Samsung Gear 360 and the DJI Inspire 1, it allowed the researcher to capture aerial 360-degree video. The paper documented the process of retrofitting the 360-camera onto the drone. Research findings on why certain drones are suitable for the 360-degree camera will be presented. A user study was conducted to gauge the usability for comparing aerial VR360 being experienced on hand-held multimedia tablets and head-mount-devices (HMD). In this paper we describe the proposed configuration and workflow of aerial 360-video and identifying its potential capabilities and limitation, a user evaluation study and directions for future work.
Microbial eukaryotes have adapted to hypoxia by horizontal acquisitions of a gene involved in rhodoquinone biosynthesis

Under hypoxic conditions, some organisms use an electron transport chain consisting of only complex I and II (CII) to generate the proton gradient essential for ATP production. In these cases, CII functions as a fumarate reductase that accepts electrons from a low electron potential quinol, rhodoquinol (RQ). To clarify the origins of RQ-mediated fumarate reduction in eukaryotes, we investigated the origin and function of rquA, a gene encoding an RQ biosynthetic enzyme. RquA is very patchily distributed across eukaryotes and bacteria adapted to hypoxia. Phylogenetic analyses suggest lateral gene transfer (LGT) of rquA from bacteria to eukaryotes occurred at least twice and the gene was transferred multiple times amongst protists. We demonstrate that RquA functions in the mitochondrion-related organelles of the anaerobic protist Pygsuia and is correlated with the presence of RQ. These analyses reveal the role of gene transfer in the evolutionary remodeling of mitochondria in adaptation to hypoxia.
News web page classification using url content and structure attributes

The incentive for this work originates from the need of retrieving useful web news pages from the Indian news websites corpus. News web pages contrast from other web pages; it is mainly vital to recognize web news accurately for precise classification. We will likely locate a simple yet efficient technique to mine news articles from web corpus. To accomplish this task, the automatic recognition method has been recommended for news web page classification that uses classification rules based on a combination of content, structure and uniform resource locator (URL) attributes. We gathered news web documents from 10 different news websites. We use Naïve Bayes algorithm to distinguish news articles from non-news articles examples advertisements, not related links.
BOOSTING THE INVERSE INTERPOLATION PROBLEM BY A SUM OF DECAYING EXPONENTIALS USING AN ALGEBRAIC APPROACH

Abstract. An algebraic method is proposed to solve the inverse interpo lation problem for data fitting by a linear combination of decaying exponentials. The method tr ansforms the interpolation question into a problem of finding the roots of a single polynomial. The method is valida te by numerical simulations using noiseless synthetic data with excellent results. The method is applied to medica l data coming from magnetic resonance images of tumoral lesions in brain to obtain relaxation rate distribu tion functions, with results that are trustworthy and fast when compared with inverse Laplace methods.
So we think you can learn: how student perceptions affect learning*

Abstract Recent experiences in rehearsals have led us to question how student dancers perceive the culture of rehearsal. We are interested in how the influence of shows like So You Think You Can Dance affects student expectations. How do students from competitive dance studio backgrounds approach learning in a rehearsal setting? Are there specific ways to ensure optimal learning in a rehearsal process? A qualitative evaluation is used for this research, utilizing interviews, and surveys to collect data from students enrolled in a ‘Rehearsal and Performance’ course at three separate institutions, to broaden the scope of the data collection. Our research outcomes will add to the current knowledge of the field, by analyzing the learning opportunities in a rehearsal culture and the intersection of student perceptions and experience.
Simulation of metallic nano-structures by using a hybrid FDTD-ADI subgridding method

We present a novel hybrid mesh refinement method for the simulation of dispersive metallic structures. Combining the FDTD method and an unconditionally stable ADI-FDTD scheme preserves the Courant limit while providing higher spatial resolution in refined areas. The subgridding method is developed for the simulation of dispersive metals using an auxiliary differential equation approach. The algorithm performs roughly two times faster than a conventional mesh refinement method.
Relational processing of RDF queries: a survey

The Resource Description Framework (RDF) is a flexible model for representing information about resources in the web. With the increasing amount of RDF data which is becoming available, efficient and scalable management of RDF data has become a fundamental challenge to achieve the SemanticWeb vision. The RDF model has attracted the attention of the database community and many researchers have proposed different solutions to store and query RDF data efficiently. This survey focuses on using relational query processors to store and query RDF data. We provide an overview of the different approaches and classify them according to their storage and query evaluation strategies.
TN PS High Performance Photon Counting Correlation Measurements by Advanced TCSPC Techniques

For light generated by nonlinear effects, by quantum dots [1, 2, 3, 4] or single molecules [5] this is not necessarily the case. When a single molecule has absorbed a photon it cannot absorb and emit a second photon until it has not returned to the ground state. Thus, the fluorescence photons are not longer independent. Instead, there is a correlation or ‘antibunching’ on the time scale of the fluorescence lifetime. An even more pronounced antibunching can be achieved in optically or electrically excited quantum dots. Investigation of these effects requires the detection and correlation of single photons on the ps and ns scale.
The matricellular protein CCN 3 regulates NOTCH 1 signalling in chronic myeloid leukaemia

Deregulated NOTCH1 has been reported in lymphoid leukaemia, although its role in chronic myeloid leukaemia (CML) is not well established. We previously reported BCR-ABL down-regulation of a novel haematopoietic regulator, CCN3, in CML; CCN3 is a non-canonical NOTCH1 ligand. This study characterizes the NOTCH1–CCN3 signalling axis in CML. In K562 cells, BCR-ABL silencing reduced full-length NOTCH1 (NOTCH1-FL) and inhibited the cleavage of NOTCH1 intracellular domain (NOTCH1-ICD), resulting in decreased expression of the NOTCH1 targets c-MYC and HES1. K562 cells stably overexpressing CCN3 (K562/CCN3) or treated with recombinant CCN3 (rCCN3) showed a significant reduction in NOTCH1 signalling (> 50% reduction in NOTCH1-ICD, p < 0.05). Gamma secretase inhibitor (GSI), which blocks NOTCH1 signalling, reduced K562/CCN3 colony formation but increased that of K562/control cells. GSI combined with either rCCN3 or imatinib reduced K562 colony formation with enhanced reduction of NOTCH1 signalling observed with combination treatments. We demonstrate an oncogenic role for NOTCH1 in CML and suggest that BCR-ABL disruption of NOTCH1–CCN3 signalling contributes to the pathogenesis of CML.  2013 The Authors.

The coiled-coil membrane protein golgin-84 is a novel rab effector required for Golgi ribbon formation

Fragmentation of the mammalian Golgi apparatus during mitosis requires the phosphorylation of a specific subset of Golgi-associated proteins. We have used a biochemical approach to characterize these proteins and report here the identification of golgin-84 as a novel mitotic target. Using cryoelectron microscopy we could localize golgin-84 to the cis-Golgi network and found that it is enriched on tubules emanating from the lateral edges of, and often connecting, Golgi stacks. Golgin-84 binds to active rab1 but not cis-Golgi matrix proteins. Overexpression or depletion of golgin-84 results in fragmentation of the Golgi ribbon. Strikingly, the Golgi ribbon is converted into mini-stacks constituting only ∼25% of the volume of a normal Golgi apparatus upon golgin-84 depletion. These mini-stacks are able to carry out protein transport, though with reduced efficiency compared with a normal Golgi apparatus. Our results suggest that golgin-84 plays a key role in the assembly and maintenance of the Golgi ribbon in mammalian cells.
Selenium influences growth via thyroid hormone status in broiler chickens

As there is a possibility that Se influences the growth of animals via thyroid hormone metabolism, the following three experiments were undertaken in order to determine the effects of dietary Se on growth, skeletal muscle protein turnover and thyroid hormone status in broiler chickens. Broiler chickens were raised on a Se-deficient diet until 12 d of age and then used for the experiments. In Experiment 1, twenty-eight birds were randomly assigned to four groups and fed purified diets with the following amounts of Se supplementation: 0·0, 0·1, 0·3 and 0·5 mg Se/kg diet. Dietary Se supplementation significantly increased plasma 3,5,3′-triiodothyronine (T3) concentration and improved growth, while plasma thyroxine (T4) concentration was decreased. In Experiment 2, twenty-eight birds were assigned to four groups and fed either a Se-deficient diet or a Se-supplemented diet (0·3 mg Se/kg diet) with or without the supplementation of iopanoic acid, a specific inhibitor of 5′-deiodinase (5 mg/kg diet). The growth was promoted and feed efficiency was improved by dietary Se supplementation as was also observed in Experiment 1. However, this effect of Se was halted by iopanoic acid supplementation. Hepatic 5′-deiodinase activity was elevated by Se and inhibited by iopanoic acid. In Experiment 3, birds were fed on the following diets to show that Se influences growth of birds via thyroid hormone metabolism: Se-deficient diet, Se-supplemented diets (0·1 and 0·3 mg/kg) and T3 supplemented diets (0·1 and 0·3 mg/kg diet). Lower dietary T3 supplementation (0·1 mg/kg diet) resulted in growth promotion similar to Se supplementation, while higher level of T3 caused growth depression. Furthermore, it was observed that the rate of skeletal muscle protein breakdown tended to be increased by Se similarly to the effect of T3. In conclusion, it was shown in the present study that Se deficiency depresses growth of broilers by inhibiting hepatic 5′-deiodinase activity which causes lower plasma T3 concentration.
DIVERT for realistic simulation of heterogeneous vehicular networks

Simulation of vehicular networks has been extensively studied in the last few years. In order to have an holistic view of the network functioning, communications and vehicle mobility aspects should be modeled in detail and fully integrated. This article presents a tool for simulating heterogeneous vehicular networks. The existing microscopic traffic simulator, DIVERT, has been extended by adding NS-3 support resulting in a very tightly integrated simulator. The feasibility of the approach has been tested by means of an application example: in-vehicle traffic lights. The provided results demonstrate the superior performance and the scalability of this novel simulator.
Seeking Help for Depression: Applying the Health Belief Model to Illness Narratives

ABSTRACT Many individuals with depression experience difficulty seeking help. To better understand the help-seeking process, we analyzed narratives produced during interviews with individuals who sought treatment. We examined these narratives within the framework of the health belief model and then engaged in emergent, thematic coding within each of the categories. Our findings suggest that, for depressed individuals, one’s uncertainty regarding the condition and treatment drives each element of the health belief model. The main barrier preventing help-seeking was fear of the unknown treatment process. Interpersonal cues to action served to reduce uncertainty by providing guidance and confirmation that help was needed. Interventions should target friends and family of depressed individuals and provide information regarding the treatment process to effectively reduce uncertainty and drive help-seeking.
Expression Pattern of Abscisic Acid Insensitive 3 in Soybean ( Glycine max L . Merr . ) and its Interaction Mechanism between Storage Protein Gene Promoter

Among the transcription factors of Arabidopsis, abscisic acid insensitive 3 (ABI3) was mediated in accumulating of seed protein. In soybean (Glycine max L. Merr.), the mRNA expression content of ABI3-like (two members: GmABI3-8 and GmABI3-18) and storage protein genes are significantly correlated. However, the expression of ABI3-like in different plant tissues or during seed germination as well as the interaction mechanism between ABI3-like and the storage protein gene still not known. In current research, the transcriptional expression of ABI3-like was studied supplementary, and the interaction mechanism with the storage protein gene was demonstrated in the yeast one-hybrid system. The results demonstrated that the mRNA content of soybean ABI3-like in the seeds were significantly higher than those of other plant tissues (P<0.05) and decreased with time during seed germination. In the yeast one-hybrid system, GmABI3-8 could bind to the RY motif located in the promoter of the storage protein gene and positively regulated its expression. The RY motif as a transcriptional activity regulation factor was related to the expression of storage protein genes in soybean. Our results showed that ABI3-like has a crucial function in storage proteins accumulation and may facilitate further molecular breeding methods for developing highprotein soybean varieties. © 2018 Friends Science Publishers
Splitting the “ I ”s and Crossing the “ You ”s: Context, Speech Acts and Grammar

The occurrence of split utterances (SUs) in dialogue raises many puzzles for grammar formalisms, from formal to pragmatic and even philosophical issues. This paper presents an account of some of the formal details that grammars need to incorporate in order to accommodate them. Using Dynamic Syntax (DS), we illustrate how by incorporating essential interaction with the context into the grammar itself, we can deal with speaker change in SUs: not only its effects on indexicals I and you , but also the multiple illocutionary forces that can arise. We also introduce a Split Turn Taking Puzzle (STTP) showing that the current speaker and the agent of the resulting speech act are not necessarily the same.
Patient-reported outcomes and survivorship in radiation oncology: overcoming the cons.

PURPOSE Although patient-reported outcomes (PROs) have become a key component of clinical oncology trials, many challenges exist regarding their optimal application. The goal of this article is to methodically review these barriers and suggest strategies to overcome them. This review will primarily focus on radiation oncology examples, will address issues regarding the "why, how, and what" of PROs, and will provide strategies for difficult problems such as methods for reducing missing data. This review will also address cancer survivorship because it closely relates to PROs. METHODS Key articles focusing on PROs, quality of life, and survivorship issues in oncology trials are highlighted, with an emphasis on radiation oncology clinical trials. Publications and Web sites of various governmental and regulatory agencies are also reviewed. RESULTS The study of PROs in clinical oncology trials has become well established. There are guidelines provided by organizations such as the US Food and Drug Administration that clearly indicate the importance of and methodology for studying PROs. Clinical trials in oncology have repeatedly demonstrated the value of studying PROs and suggested ways to overcome some of the key challenges. The Radiation Therapy Oncology Group (RTOG) has led some of these efforts, and their contributions are highlighted. The current state of cancer survivorship guidelines is also discussed. CONCLUSION The study of PROs presents significant benefits in understanding and treating toxicities and enhancing quality of life; however, challenges remain. Strategies are presented to overcome these hurdles, which will ultimately improve cancer survivorship.
Impact of tropospheric ozone on the Euro‐Mediterranean vegetation

The impact of ozone (O3) on European vegetation is largely under‐investigated, despite huge areas of Europe are exposed to high O3 levels and which are expected to increase in the next future. We studied the potential effects of O3 on photosynthesis and leaf area index (LAI) as well as the feedback between vegetation and atmospheric chemistry using a land surface model (ORCHIDEE) at high spatial resolution (30 km) coupled with a chemistry transport model (CHIMERE) for the whole year 2002. Our results show that the effect of tropospheric O3 on vegetation leads to a reduction in yearly gross primary production (GPP) of about 22% and a reduction in LAI of 15–20%. Larger impacts have been found during summer, when O3 reaches higher concentrations. During these months the maximum GPP decrease is up to 4 g C m−2 day−1, and the maximum LAI reduction is up to 0.7 m2 m−2. Since CHIMERE uses the LAI computed by ORCHIDEE to estimate the biogenic emissions, a LAI reduction may have severe implications on the simulated atmospheric chemistry. We found a large change in O3 precursors that however leads to small changes in tropospheric O3 concentration, while larger changes have been found for surface NO2 concentrations.
Influence of Acid Volatile Sulfides and Metal Concentrations on Metal Partitioning in Contaminated Sediments

The influence of acid volatile sulfide (AVS) on the partitioning of Cd, Ni, and Zn in porewater (PW) and sediment as reactive metals (SEM, simultaneously extracted metals) was investigated in laboratory microcosms. Two spiking procedures were compared, and the effects of vertical geochemical gradients and infaunal activity were evaluated. Sediments were spiked with a Cd−Ni−Zn mixture (0.06, 3, 7.5 μmol/g, respectively) containing four levels of AVS (0.5, 7.5, 15, 35 μmol/g). The results were compared to sediments spiked with four levels of Cd−Ni−Zn mixtures at one AVS concentration (7.5 μmol/g). A vertical redox gradient was generated in each treatment by an 18-d incubation with an oxidized water column. [AVS] in the surface sediments decreased by 65−95% due to oxidation during incubation; initial [AVS] was maintained at 0.5−7.5 cm depth. PW metal concentrations were correlated with [SEM − AVS] among all data. But PW metal concentrations were variable, causing the distribution coefficient, Kdpw (the ratio.
