Authors: Ali Sayin Ş. , Yavuz Nurdan , Içöz Serap 
Published: December 2017

AbstractThe Çankırı Basin is one of the largest Cenozoic basins in Central Anatolia, Turkey and contains possible economic hydrocarbon and evaporite reserves. Gypsum is the dominant mineral in the evaporite-bearing Pliocene deposits of the Çankırı Basin. In claystones, the abundance of smectite, dolomite, illite/mica and chlorite in association with minor amounts of mixed-layer chlorite-smectite, mica-vermiculite, amphibole, serpentine, quartz and feldspar together indicate an alkaline environment. Minor kaolinite is also present in some clay samples. Smectite is both detrital and authigenic. Palynological analysis revealed the existence of a mixed forest (Pinus, Cathaya, Tsuga, Cedrus, Abies, Quercus, Ulmus, Juglans, Pterocarya, Acer, Carya, Carpinus, Fagus) dominated byPinuswith a widespread herbaceous understory (Poaceae) interspersed sparsely with open areas occupied by Asteraceae. This flora reflects warm-temperate and humid climatic condition. δ13C analyses have shown that the vegetation was dominated by C3 plants.

Published: December 2017

Purpose Although several feasibility studies have demonstrated the safety of adjuvant concurrent chemoradiotherapy (CRT) for locally advanced or incompletely resected non–small-cell lung cancer (NSCLC), it remains uncertain whether this approach is superior to sequential chemotherapy followed by postoperative radiotherapy (C→PORT). We sought to determine the most effective treatment sequence. Patients and Methods Using the National Cancer Database, we selected two cohorts of patients with nonmetastatic NSCLC who had received at least a lobectomy followed by multiagent chemotherapy and radiotherapy; cohort one included patients with R0 resection and pN2 disease, whereas cohort two included patients with R1-2 resection regardless of nodal status. Overall survival (OS) was examined using a propensity score–matched analysis with a shared frailty Cox regression. Results A total of 747 patients in cohort one and 277 patients in cohort two were included, with a median follow-up of 32.8 and 27.9 months, respectively. The median OS was 58.8 months for patients who received C→PORT versus 40.4 months for patients who received CRT in cohort one (log-rank P < .001). For cohort two, the median OS was 42.6 months for patients who received C→PORT versus 38.5 months for patients who received CRT (log-rank P = .42). After propensity score matching, C→PORT remained associated with improved OS compared with CRT in cohort one (hazard ratio, 1.35; P = .019), and there was no statistical difference in OS between the sequencing groups for cohort two (hazard ratio, 1.35; P = .19). Conclusion Patients with NSCLC who undergo R0 resection and are found to have pN2 disease have improved outcomes when adjuvant chemotherapy is administered before, rather than concurrently with, radiotherapy. For patients with positive margins after surgery, there is not a clear association between treatment sequencing and survival.
The Clinical Utility of Noninvasive Pulse Co-oximetry Hemoglobin Measurements in Dark-Skinned Critically Ill Patients
Authors: Murphy Susan M. , Omar Shahed 
Published: December 2017

BACKGROUND:
The primary objective of this study was to assess the clinical usefulness of a point-of-care device which measures hemoglobin noninvasively (SpHb) in a group of critically ill participants with dark skin pigmentation.

METHODS:
One hundred forty-six adult and pediatric participants from a multidisciplinary intensive care unit had intermittent readings of noninvasive hemoglobin measurements performed at a minimum of 4 hourly intervals. A total of 371 readings were analyzed. Concurrent blood samples were taken to assess hemoglobin levels using point-of-care blood gas analyzer, as well as sent to a central laboratory where hemoglobin was measured using the sodium lauryl sulfate method. Bland-Altman plots were constructed to assess the agreement between results from the 2 point-of-care devices with the reference standard (laboratory hemoglobin).

RESULTS:
SpHb exhibited significant bias when compared to laboratory hemoglobin, while blood gas hemoglobin did not. Mean bias for SpHb was +1.64 with limits of agreement of −1.03 to 4.31 compared to blood gas hemoglobin which showed a bias of 0.26 and limits of agreement of −0.84 to 1.37. The magnitude of the bias for SpHb increased with increasing mean hemoglobin levels. Of all the additional study variables assessed for effect on the bias, only Acute Physiology and Chronic Health Evaluation II score in adult patients (P < .0001) and mean arterial blood pressure (P = .001) had an effect. Skin pigmentation did not have any effect on the magnitude of bias.

CONCLUSIONS:
Noninvasive Hemoglobin measurement is a promising tool in dark-skinned critically ill patients with low hemoglobin levels, but requires further refinements for it to have clinical usefulness.
Sensing in a noisy world: lessons from auditory specialists, echolocating bats
Authors: Corcoran Aaron J. , Moss Cynthia F. 
Published: December 2017

ABSTRACT
All animals face the essential task of extracting biologically meaningful sensory information from the ‘noisy’ backdrop of their environments. Here, we examine mechanisms used by echolocating bats to localize objects, track small prey and communicate in complex and noisy acoustic environments. Bats actively control and coordinate both the emission and reception of sound stimuli through integrated sensory and motor mechanisms that have evolved together over tens of millions of years. We discuss how bats behave in different ecological scenarios, including detecting and discriminating target echoes from background objects, minimizing acoustic interference from competing conspecifics and overcoming insect noise. Bats tackle these problems by deploying a remarkable array of auditory behaviors, sometimes in combination with the use of other senses. Behavioral strategies such as ceasing sonar call production and active jamming of the signals of competitors provide further insight into the capabilities and limitations of echolocation. We relate these findings to the broader topic of how animals extract relevant sensory information in noisy environments. While bats have highly refined abilities for operating under noisy conditions, they face the same challenges encountered by many other species. We propose that the specialized sensory mechanisms identified in bats are likely to occur in analogous systems across the animal kingdom.

Ενώ οι περισσότεροι συγγραφείς και ερευνητές συμφωνούν για τη σημασία της γονικής εμπλοκής στην ενίσχυση της ποιότητας της εκπαίδευσης, υπάρχει ασάφεια αναφορικά με την προέλευση, τη φύση και τις εννοιολογικές αποχρώσεις που συνιστούν τη δομή της. Η παρούσα εργασία εστιάζει στην έννοια και τη λειτουργία της γονικής εμπλοκής υπό το πρίσμα του «εκπαιδευτικού θύλακα» του παιδιού. Πρόκειται για ένα θεωρητικό σχήμα με εμπειρική εφαρμογή, το οποίο προκύπτει συνδυάζοντας τις βασικές θεωρητικές θέσεις της βιο-οικολογικής προσέγγισης του Urie Bronfenbrenner και του «αναπτυξιακού θύλακα» των Super και Harkness. Ιδιαίτερη έμφαση δίνεται όχι μόνο στις πρακτικές που εφαρμόζουν οι γονείς αλλά και στις σχέσεις που αναπτύσσουν και τις απόψεις που διαμορφώνουν καθώς εμπλέκονται στην εκπαίδευση του παιδιού, στη βάση των διαφοροποιημένων αναπτυξιακών και εκπαιδευτικών αναγκών των παιδιών σε κάθε ηλικιακή περίοδο.

Published: December 2017

Abstract. Matching agricultural tractors to implements towed by the drawbar is one of the important aspects of machinery management for ensuring optimum performance and fuel cost savings. A field deployable tractor draft force measurement and data acquisition system was developed and evaluated as part of this research project. A drawbar instrumented to measure draft force in field operating conditions was developed and statically calibrated. The drawbar was calibrated by applying loads from 4.45 to 134 kN using a hydraulic cylinder connected to a 444.8 kN load cell. Testing was conducted with the drawbar installed on a tractor on a concrete track. The Nebraska Tractor Test Laboratory (NTTL) load car was used for applying draft loads to evaluate the instrumented drawbar. The track test consisted of seven loads corresponding to maximum power in seven gears. The draft forces as measured by the drawbar were compared to the draft measurements recorded by the load car. The error between draft force measurements of the instrumented drawbar and the load car measurements ranged from 0.21 kN (0.27%) to 0.99 kN (2.88%).There were no statistically significant differences between drawbar and load car measurements confirming that the drawbar force measurement and data acquisition (DAQ) system developed as part of this research can be used for field use.

Composing for a latency-rich environment
Authors: Rofe Michael , Geelhoed Erik 
Published: December 2017

Abstract
Three new works were commissioned for the pilot performance of Online Orchestra: In Sea-Cold Lyonesse by John Pickard, Spiritus Telecommunitas by Federico Reuben and Re-Tracing by Jim Aitchison. This article brings together post-project interviews with composers and detailed analyses of the final compositions in order to document how composers approached the challenge of writing music for a latency-rich environment. Solutions include the use of distributed textures, polyrhythm and ostinati, blurred transitions, slow rates of harmonic change, layered textures and semi-improvised rhythmic notation. This leads to consideration of the medium of Online Orchestra – a telematic performance environment for distributed young and amateur musicians to make music together – and the conclusion that latency-rich environments hold significant potential for composers.

Authors: Ruciński Adam , Rusowicz Artur 
Published: December 2017

Abstract
This paper provides some information about thermoelectric technology. Some new materials with improved figures of merit are presented. These materials in Peltier modules make it possible to generate electric current thanks to a temperature difference. The paper indicates possible applications of thermoelectric modules as interesting tools for using various waste heat sources. Some zero-dimensional equations describing the conditions of electric power generation are given. Also, operating parameters of Peltier modules, such as voltage and electric current, are analyzed. The paper shows chosen characteristics of power generation parameters. Then, an experimental stand for ongoing research and experimental measurements are described. The authors consider the resistance of a receiver placed in the electric circuit with thermoelectric elements. Finally, both the analysis of experimental results and conclusions drawn from theoretical findings are presented. Voltage generation of about 1.5 to 2.5 V for the temperature difference from 65 to 85 K was observed when a bismuth telluride thermoelectric couple (traditionally used in cooling technology) was used.

Robust and Flexible Estimation of Stochastic Mediation Effects: A Proposed Method and Example in a Randomized Trial Setting
Authors: Rudolph Kara E. , Sofrygin Oleg , Zheng Wenjing , van der Laan Mark J. 
Published: December 2017

Abstract

Background
Causal mediation analysis can improve understanding of the mechanisms underlying epidemiologic associations. However, the utility of natural direct and indirect effect estimation has been limited by the assumption of no confounder of the mediator-outcome relationship that is affected by prior exposure (which we call an intermediate confounder)–-an assumption frequently violated in practice.

Methods
We build on recent work that identified alternative estimands that do not require this assumption and propose a flexible and double robust targeted minimum loss-based estimator for stochastic direct and indirect effects. The proposed method intervenes stochastically on the mediator using a distribution which conditions on baseline covariates and marginalizes over the intermediate confounder.

Results
We demonstrate the estimator’s finite sample and robustness properties in a simple simulation study. We apply the method to an example from the Moving to Opportunity experiment. In this application, randomization to receive a housing voucher is the treatment/instrument that influenced moving with the voucher out of public housing, which is the intermediate confounder. We estimate the stochastic direct effect of randomization to the voucher group on adolescent marijuana use not mediated by change in school district and the stochastic indirect effect mediated by change in school district. We find no evidence of mediation.

Conclusions
Our estimator is easy to implement in standard statistical software, and we provide annotated R code to further lower implementation barriers.
Security Aspects in Resource Management Systems in Distributed Computing Environments
Authors: Adamski Marcin , Kurowski Krzysztof , Mika Marek , Piątek Wojciech , Węglarz Jan 
Published: December 2017

Abstract
In many distributed computing systems, aspects related to security are getting more and more relevant. Security is ubiquitous and could not be treated as a separated problem or a challenge. In our opinion it should be considered in the context of resource management in distributed computing environments like Grids and Clouds, e.g. scheduled computations can be much delayed because of cyber-attacks, inefficient infrastructure or users valuable and sensitive data can be stolen even in the process of correct computation. To prevent such cases there is a need to introduce new evaluation metrics for resource management that will represent the level of security of computing resources and more broadly distributed computing infrastructures. In our approach, we have introduced a new metric called reputation, which simply determines the level of reliability of computing resources from the security perspective and could be taken into account during scheduling procedures. The new reputation metric is based on various relevant parameters regarding cyber-attacks (also energy attacks), administrative activities such as security updates, bug fixes and security patches. Moreover, we have conducted various computational experiments within the Grid Scheduling Simulator environment (GSSIM) inspired by real application scenarios. Finally, our experimental studies of new resource management approaches taking into account critical security aspects are also discussed in this paper.

AbstractEuthymi, Crassicostatum and Callisto ammonite subzones, correlable with Paramimounum, Picteti, and Alpillensis subzones and probably with the Late Berriasian Otopeta Subzone of the Boissieri Standard Zone have been recognized in calcareous clays of the Berriasian-Valanginian boundary sequence in the Feodosiya district (eastern Crimea). The ammonite Leptoceras studeri (Ooster) suggests Late Berriasian to Early Valanginian age. Geomagnetic polarity indicates M16-M14r magnetozones. Therefore, the base of the Valanginian sequence in eastern Crimea should be placed within the M14r magnetozone.
Late Permian volcanic dykes in the crystalline basement of the Považský Inovec Mts. (Western Carpathians): U–Th–Pb zircon SHRIMP and monazite chemical dating

Published: December 2017

AbstractThis paper presents geochronological data for the volcanic dykes located in the northern Považský Inovec Mts. The dykes are up to 5 m thick and tens to hundreds of metres long. They comprise variously inclined and oriented lenses, composed of strongly altered grey-green alkali basalts. Their age was variously interpreted and discussed in the past. Dykes were emplaced into the Tatricum metamorphic rocks, mostly consisting of mica schists and gneisses of the Variscan (early Carboniferous) age. Two different methods, zircon SHRIMP and monazite chemical dating, were applied to determine the age of these dykes. U-Pb SHRIMP dating of magmatic zircons yielded the concordia age of 260.2 ± 1.4 Ma. The Th-U-Pb monazite dating of the same dyke gave the CHIME age of 259 ± 3Ma. Both ages confirm the magmatic crystallization at the boundary of the latest Middle Permian to the Late Permian. Dyke emplacement was coeval with development of the Late Paleozoic sedimentary basin known in the northern Považský Inovec Mts. and could be correlated with other pre-Mesozoic Tethyan regions especially in the Southern Alps.

Published: December 2017

Abstract
Silkworm pupae protein (SPP) was pretreated by different processing (heat/alkali/pepsin) and then hydrolyzed by five proteases (trypsin/flavorzyme/papain/protamex/alcalase), respectively. It was found that the combination of heat pretreatment and alkali pretreatment followed by enzymatic hydrolysis with trypsin and flavorzyme could remarkably improve the protein recovery. The hydrolysates obtained from silkworm pupae protein hydrolyzed with trypsin and flavorzyme were stable at the pH range of 4.0–8.0, remaining 95 % of its original reducing power and 90 % of its OH• scavenging activity. However, they were susceptible to alkaline treatments (pH > 10.0) and lost >30 % of their antioxidant activities. Pasteurization (65 °C × 30 min) or autoclaving sterilization (121 °C × 20 min) did not show notable effects on the antioxidant activities. It was concluded that silkworm pupae protein hydrolysates (SPPH) were better to be applied in either neutral or acidic food system rather than in alkaline conditions.

Abstract
This study addresses the phenomenon called “spacing out” or “delay” to show that speaking and writing condition the language users to assume distinct conceptions of language production, thereby motivating significantly different (uses of) grammatical devices within as well as across languages. We demonstrate that mental gaze monitoring and linguistic form manipulation serve as language production management in the speech event and writing event conceptions, respectively.

Published: December 2017

AbstractThe significance of the issue of an effective mode of passenger transport is currently increasing. On the one hand, there is the increasing economic demand of public passenger transport, on the other hand, there is the growing traffic share of individual automobile transport. The objective of the paper is to analyze public passenger transport without mutual integration of individual transport systems resulting in the fact that it is not sufficiently able to compete with individual automobile transport. It is proposed the integration of different modes of public passenger transport as a way to increase the competitiveness of public passenger transport. Aim of this paper is to analyze the individual elements of integration systems and describe why integration of public passenger transport systems is needed.
