Touch and You’re Trapp(ck)ed: Quantifying the Uniqueness of Touch Gestures for Tracking
Authors: Masood Rahat , Zhao Benjamin Zi Hao , Asghar Hassan Jameel , Kaafar Mohamed Ali 
Published: February 2018

Abstract
We argue that touch-based gestures on touch-screen devices enable the threat of a form of persistent and ubiquitous tracking which we call touch-based tracking. Touch-based tracking goes beyond the tracking of virtual identities and has the potential for cross-device tracking as well as identifying multiple users using the same device. We demonstrate the likelihood of touch-based tracking by focusing on touch gestures widely used to interact with touch devices such as swipes and taps.. Our objective is to quantify and measure the information carried by touch-based gestures which may lead to tracking users. For this purpose, we develop an information theoretic method that measures the amount of information about users leaked by gestures when modelled as feature vectors. Our methodology allows us to evaluate the information leaked by individual features of gestures, samples of gestures, as well as samples of combinations of gestures. Through our purpose-built app, called TouchTrack, we gather gesture samples from 89 users, and demonstrate that touch gestures contain sufficient information to uniquely identify and track users. Our results show that writing samples (on a touch pad) can reveal 73.7% of information (when measured in bits), and left swipes can reveal up to 68.6% of information. Combining different combinations of gestures results in higher uniqueness, with the combination of keystrokes, swipes and writing revealing up to 98.5% of information about users. We further show that, through our methodology, we can correctly re-identify returning users with a success rate of more than 90%.

Published: February 2018

AbstractHow environmental conditions influence current distributions of organisms at the local scale in sensitive High Arctic freshwaters is essential to understand in order to better comprehend the cascading consequences of the ongoing climate change. This knowledge is also important background data for paleolimnological assessments of long-term limnoecological changes and in describing the range of environmental variability. We sampled five limnologically different freshwater sites from the Fuglebergsletta marine terrace in Hornsund, southern Svalbard, for aquatic invertebrates. Invertebrate communities were tested against non-climatic environmental drivers as limnological and catchment variables. A clear separation in the communities between the sites was observed. The largest and deepest lake was characterized by a diverse Chironomidae community but Cladocera were absent. In a pond with marine influence, crustaceans, such as Ostracoda, Amphipoda, and calanoid Copepoda were the most abundant invertebrates. Two nutrient-rich ponds were dominated by a chironomid,Orthocladius consobrinus, whereas themost eutrophic pond was dominated by the cladoceranDaphnia pulex, suggesting decreasing diversity along with the trophic status. Overall, nutrient related variables appeared to have an important influence on the invertebrate community composition and diversity, the trophic state of the sites being linked with their exposure to geese guano. Other segregating variables included water color, presence/absence of fish, abundance of aquatic vegetation and lake depth. These results suggest that since most of these variables are climate-driven at a larger scale, the impacts of the ongoing climate change will have cumulative effects on aquatic ecosystems.
Comparison of acoustical and optical zooplankton measurements using an acoustic scattering model: A case study from the Arctic frontal zone
Authors: Szczucka Joanna , Trudnowska Emilia , Hoppe Łukasz , Błachowiak-Samołyk Katarzyna 
Published: February 2018

Abstract
High-frequency acoustic measurements supplemented by a modern optical method, Laser Optical Plankton Counter (LOPC), allowed us to perform a comparative analysis through the application of a mathematical model. We have studied the correspondence between measured and modelled echoes from zooplankton aggregations consisted mainly of two Calanus species. Data were collected from the upper 50 m water layer within the hydrographical frontal zone on the West Spitsbergen Shelf. The application of a “high-pass” model of sound scattering by fluid-like particles to the distribution of zooplankton sizes measured by LOPC resulted mostly in very good agreement between the measured (420 kHz BioSonics) and modelled values, except for cases with very low zooplankton abundance or with occurrence of stronger scatterers (e.g. macrozooplankton, fish). An acoustic model validated for the elastic parameters of zooplankton confirmed that particles smaller than 1mmin diameter, although highly abundant, did not contribute significantly to the sound scattering process at a frequency of 420 kHz. The implementation of diverse complementary methods has great potential to obtain high spatial and temporal resolution in zooplankton distribution studies; however, their compatibility has to be tested first.

Published: February 2018

AbstractThe study of material science has been long devoted to the disentanglement of bulk structures which mainly entails finding the inner structure of materials. That structure is accountable for a major portion of materials’ properties. Yet, as our knowledge of these “backbones” enlarged so did the interest for the materials’ boundaries properties which means the properties at the frontier with the surrounding environment that is called interface. The interface is thus to be understood as the sum of the material’s surface plus the surrounding environment be it in solid, liquid or gas phase. The study of phenomena at this interface requires both the use of experimental and theoretical techniques and, above all, a wise combination of them in order to shed light over the most intimate details at atomic, molecular and mesostructure levels. Here, we report several cases to be used as proof of concept of the results achieved when studying interface phenomena by combining a myriad of experimental and theoretical tools to overcome the usual limitation regardind  atomic detail, size and time scales and systems of complex composition. Real world examples of the combined experimental-theoretical work and new tools, software, is offered to the readers.
G protein-coupled receptor-receptor interactions give integrative dynamics to intercellular communication
Authors: Guidolin Diego , Marcoli Manuela , Tortorella Cinzia , Maura Guido , Agnati Luigi F. 
Published: February 2018

Abstract
The proposal of receptor-receptor interactions (RRIs) in the early 1980s broadened the view on the role of G protein-coupled receptors (GPCR) in the dynamics of the intercellular communication. RRIs, indeed, allow GPCR to operate not only as monomers but also as receptor complexes, in which the integration of the incoming signals depends on the number, spatial arrangement, and order of activation of the protomers forming the complex. The main biochemical mechanisms controlling the functional interplay of GPCR in the receptor complexes are direct allosteric interactions between protomer domains. The formation of these macromolecular assemblies has several physiologic implications in terms of the modulation of the signaling pathways and interaction with other membrane proteins. It also impacts on the emerging field of connectomics, as it contributes to set and tune the synaptic strength. Furthermore, recent evidence suggests that the transfer of GPCR and GPCR complexes between cells via the exosome pathway could enable the target cells to recognize/decode transmitters and/or modulators for which they did not express the pertinent receptors. Thus, this process may also open the possibility of a new type of redeployment of neural circuits. The fundamental aspects of GPCR complex formation and function are the focus of the present review article.
Biomarkers for detection, prognosis and therapeutic assessment of neurological disorders
Authors: Singh Sarita , Gupta Sunil Kumar , Seth Prahlad Kishore 
Published: February 2018

AbstractNeurological disorders have aroused a significant concern among the health scientists globally, as diseases such as Parkinson’s, Alzheimer’s and dementia lead to disability and people have to live with them throughout the life. Recent evidence suggests that a number of environmental chemicals such as pesticides (paraquat) and metals (lead and aluminum) are also the cause of these diseases and other neurological disorders. Biomarkers can help in detecting the disorder at the preclinical stage, progression of the disease and key metabolomic alterations permitting identification of potential targets for intervention. A number of biomarkers have been proposed for some neurological disorders based on laboratory and clinical studies.In silicoapproaches have also been used by some investigators. Yet the ideal biomarker, which can help in early detection and follow-up on treatment and identifying the susceptible populations, is not available. An attempt has therefore been made to review the recent advancements ofin silicoapproaches for discovery of biomarkers and their validation.In silicotechniques implemented with multi-omics approaches have potential to provide a fast and accurate approach to identify novel biomarkers.
Police Incentives, Policy Spillovers, and the Enforcement of Drug Crimes
Authors: DeAngelo Gregory J. , Gittings R. Kaj , Ross Amanda 
Published: February 2018

AbstractWe consider the impact of a low priority initiative adopted in specific jurisdictions within Los Angeles (LA) County on police behavior. Low priority initiatives instruct police to make the enforcement of low level marijuana possession offenses their “lowest priority.” Using detailed data from the LA County Sheriff’s Department, a difference-in-differences strategy suggests that the mandate resulted in fewer arrests for misdemeanor marijuana possession in adopting areas relative to non-adopting. However, the lower relative reduction in marijuana arrests appears to be driven by an increase in misdemeanor marijuana arrests in nearby areas not affected by the mandate rather than a reduction in adopting areas. We interpret this result as suggestive evidence of policy spillovers from the low priority initiative.
Practical implementation of extended Kalman filtering in chemical systems with sparse measurements
Authors: Kulikov Gennady Yu. , Kulikova Maria V. 
Published: February 2018

AbstractChemical systems are often characterized by a number of peculiar properties that create serious challenges to state estimator algorithms. They may include hard nonlinear dynamics, states subject to some constraints arising from a physical nature of the process (for example, all chemical concentrations must be nonnegative), and so on. The classical Extended Kalman Filter (EKF), which is considered to be the most popular state estimator in practice, is shown to be ineffective in chemical systems with infrequent measurements. In this paper, we discuss a recently designed version of the EKF method, which is grounded in a high-order Ordinary Differential Equation (ODE) solver with automatic global error control. The implemented global error control boosts the quality of state estimation in chemical engineering and allows this newly built version of the EKF to be an accurate and efficient state estimator in chemical systems with both short and long waiting times (i.e., with frequent and infrequent measurements). So chemical systems with variable sampling periods are algorithmically admitted and can be treated as well.
Ensemble survival tree models to reveal pairwise interactions of variables with time-to-events outcomes in low-dimensional setting

Published: February 2018

Abstract
Unraveling interactions among variables such as genetic, clinical, demographic and environmental factors is essential to understand the development of common and complex diseases. To increase the power to detect such variables interactions associated with clinical time-to-events outcomes, we borrowed established concepts from random survival forest (RSF) models. We introduce a novel RSF-based pairwise interaction estimator and derive a randomization method with bootstrap confidence intervals for inferring interaction significance. Using various linear and nonlinear time-to-events survival models in simulation studies, we first show the efficiency of our approach: true pairwise interaction-effects between variables are uncovered, while they may not be accompanied with their corresponding main-effects, and may not be detected by standard semi-parametric regression modeling and test statistics used in survival analysis. Moreover, using a RSF-based cross-validation scheme for generating prediction estimators, we show that informative predictors may be inferred. We applied our approach to an HIV cohort study recording key host gene polymorphisms and their association with HIV change of tropism or AIDS progression. Altogether, this shows how linear or nonlinear pairwise statistical interactions of variables may be efficiently detected with a predictive value in observational studies with time-to-event outcomes.
Application of Terrestrial Laser Scanner with an Integrated Thermal Camera in Non-Destructive Evaluation of Concrete Surface of Hydrotechnical Objects
Authors: Kowalska Maria , Zaczek-Peplinska Janina 
Published: February 2018

Abstract
The authors present possible applications of thermal data as an additional source of information on an object’s behaviour during the technical assessment of the condition of a concrete surface. For the study one of the most recent propositions introduced by Zoller + Fröhlich company was used, which is an integration of a thermal camera with a terrestrial laser scanner. This solution enables an acquisition of geometric and spectral data on the surveyed object and also provides information on the surface’s temperature in the selected points. A section of the dam’s downstream concrete wall was selected as the subject of the study for which a number of scans were carried out and a number of thermal images were taken at different times of the day. The obtained thermal data was confronted with the acquired spectral information for the specified points. This made it possible to carry out broader analysis of the surface and an inspection of the revealed fissure. The thermal analysis of said fissure indicated that the temperature changes within it are slower, which may affect the way the concrete works and may require further elaboration by the appropriate experts. Through the integration of a thermal camera with a terrestrial laser scanner one can not only analyse changes of temperature in the discretely selected points but on the whole surface as well. Moreover, it is also possible to accurately determine the range and the area of the change affecting the surface. The authors note the limitations of the presented solution like, inter alia, the resolution of the thermal camera.

Published: February 2018

Abstract

Objectives
Cognition and speech disorders are the most common symptoms of dementia in neurodegenerative disease. Here, we present a detailed clinical evaluation of a case of logopenic variant of primary progressive aphasia (lv-PPA), an atypical form of Alzheimer disease (AD), including cognitive testing over time, brain imaging, electrophysiology, and tests of olfactory function.

Case report
We present the case of a 58-year-old man suffering from progressive language difficulties who was finally diagnosed with lv-PPA. Clinical data included neuropsychological examinations, electrophysiology tests, neuroimaging, biomarkers, olfactory tests, and olfactory functional magnetic resonance imaging (fMRI).

Results and Discussion
The patient suffered from language disorders, including stumbling speech and forgetting appropriate words and how to pronounce some words. This had started 2 years earlier, and he had begun to deteriorate in recent months. In addition to his speech disorder, scores on the Mini Mental State Examination and Montreal cognitive assessment indicated that his cognition was affected. Structural imaging revealed no obvious hippocampal atrophy (score of 1), and molecular imaging showed hypometabolism and amyloid deposits in the temporal parietal region. The patient also presented with olfactory impairment. Although his odour detection threshold was normal, his cognitive threshold for scent recognition was significantly increased. Olfactory fMRI showed that activation of the whole brain and primary olfactory cortex was rare.

Conclusion
This case provides evidence suggesting that lv-PPA is an atypical form of AD, with symptoms including speech disorders and impaired cognition. This patient with lv-PPA presented with olfactory impairment.

Abstract
As an important plateau cereal crop, hulless barley is the principal food for the Tibetan people in China. ADP-glucose pyrophosphorylase (AGPase) is considered as the key enzyme for starch biosynthesis in plants. In this study, cDNAs encoding the small subunit (SSU I) and large subunit (LSU I) of AGPase were isolated from hulless barley. The results showed that SSU I and LSU I were 1438 and 1786 bp in length with a complete open reading frame (ORF) of 1419 and 1572 bp. The ORF-encoded polypeptides of 472 and 523 amino acids were having calculated molecular masses of 52.01 and 58.23 kDa, and the pI values were 5.59 and 6.30. In addition, phylogenetic analysis showed that SSU I and LSU I had the same phylogenetic trends with some species. Furthermore, expression levels in different growth periods and tissues of two hulless barley varieties were analyzed by quantitative reverse transcription-polymerase chain reaction. Gene expression levels of SSU I and LSU I were consistent with the total starch accumulation rate in endosperm. In conclusion, our data confirmed that SSU I and LSU I played an important role in hulless barley starch synthesis.
„Nehmt auf euch mein Joch und lernt von mir!“ (Mt 11,29). Mt 11,28–30 und die christologische Dimension der matthäischen Ethik
Authors: Konradt Matthias 
Published: February 2018

Abstract:
An analysis of the Christological dimension of Matthean ethics that discusses only Jesus’ attitude towards the Torah, which has taken centre stage in recent Matthean research, is insufficient, as Jesus’s ethical instruction does not consist only in Torah-related teaching. Moreover, Jesus himself functions as a paradigm for his disciples’ conduct. In this connection, Matt 11,28–30 bears paradigmatic significance. This text presents Jesus not as personified Wisdom, but as the humble messianic king who invites the people to take shelter under his gentle rule. Alongside Jesus’ instruction itself, the admonition to learn from him also includes the mimetic aspect of following his example. Furthermore, an adequate analysis of Matthean ethics must take into account that the development of ethically relevant elements is interwoven in the narrative development of the Jesus story and correlated with the thematic shifts in that narrative. Matt 11,28–30 is an important building block in the macrostructure of this narrative dynamic.
Petrus und der singende Hahn: Eine zeitgeschichtliche Anspielung in der markinischen Verleugnungsperikope (Mk 14,54.66–72)
Authors: Lanzinger Daniel 
Published: February 2018

Abstract:
A growing strand of scholarship assumes that Mark’s account of Peter’s denial should be understood within the context of the Neronian persecution. This paper strengthens this view by arguing that the cock whose crow reminds Peter of Jesus’ words is a hidden reference to Nero. Evidence comes from Suetonius, who testifies that a cock was indeed used as a derisive metaphor for Nero and alluded to his self-representation as an Apollo-like artist. The apparent tension between three denials and only two cock-crows in Mark 14,72 can then be taken as a proleptic allusion to a third “cock-crow”, i. e. to the Neronian persecution when Peter ultimately confessed his belonging to the disciples of Jesus instead of denying it. He is thus portrayed as a positive role model for those in the Marcan community who failed to remain steadfast during the persecution.
Hapax Legomena in Disputed Pauline Letters: A Reassessment
Authors: Nes Jermo van 
Published: February 2018

Abstract:
To argue for the pseudonymity of disputed Pauline letters on the (partial) basis of their disproportional high number of hapax legomena continues to be common practice among New Testament scholars. By means of linear regression analysis, it is shown that only 1 and 2 Timothy use significantly more hapaxes than the undisputed Pauline letters. If, however, proper noun hapaxes, hapaxes taken from citations, and hapaxes which – upon removal of its preposition – have a common lexeme are not taken into consideration, it appears that none of the disputed Pauline letters use significantly more hapaxes than the undisputed Pauline letters.
Responsabilidad social de la Psicología frente a la violencia
Authors: Vaca Vaca Patricia , Rodríguez Díaz María Clara 
Published: February 2018

En este artículo se hace un análisis sobre la responsabilidad social de la Psicología frente al fenómeno de la violencia. Se parte de su reconocimiento en este contexto como una de las problemáticas de mayor relevancia y de salud pública, que coincide con la valoración que de ella han hecho estudios realizados a nivel internacional. Se destaca la importancia de la proyección social y la formación de futuros profesionales desde la universidad, así como algunos de los estudios sobre las diferentes expresiones de violencia en este medio. Se asumen como importantes las recomendaciones planteadas en el informe mundial de la OMS sobre violencia y salud, y la comprensión de la realidad de la violencia más allá del ámbito privado e individual en el que priman criterios “curativos” o legales, para reconocerla como un hecho histórico social frente al cual la Psicología debe aportar elementos para la búsqueda de un proyecto ético/social de construcción de sujeto y comunidad. La investigación y praxis soportada en valores solidarios de respeto por el otro y formas diferentes de solucionar el conflicto, serán estrategias que deberán ser sustentadas.
