AbstractWe studied the structure, IR absorption spectra, the spectral characteristics of photoluminescence and morphology of cerium- and terbium-doped orthoborates of gadolinium and yttrium obtained by hydrothermal synthesis at 200°C, as well as solid solutions of orthoborates on the basis of yttrium, gadolinium, and lutetium with composition RECe_0.01Tb_0.1BO_3 (RE = Lu_0.5Gd_0.39, Lu_0.5Y_0.39, and Y_0.5Gd_0.39). The X-ray diffraction spectrum of yttrium orthoborate Y_1 – _ x _– _ y Ce_ x Tb_ y BO_3 is described by a hexagonal lattice with space group P 6_3/ m , which, after annealing at 970°C, transforms into a monoclinic lattice with space group C 2/ c . High-temperature annealing of the studied orthoborates leads to a multiple, more than two orders of magnitude, increase in the luminescence intensity of Tb^3+ ions when the samples are excited in the absorption band of cerium ions. This effect is the result of a significant increase in the concentration of Ce^3+ ions in the orthoborates at high temperatures. It is shown that the luminescence of terbium ions is due to energy transfer from Ce^3+ to Tb^3+, which proceeds with high efficiency (∼85%) by the mechanism of dipole-dipole interaction between cerium and terbium.

AbstractDiamond microcrystals containing silicon-vacancy (SiV) defects were synthesized by using a high-pressure high-temperature treatment of a mixture of pertinent organic-inorganic precursors. Photoluminescence of the SiV defects and its temperature dependence (80–400 K) was studied. A strong sharp zero-phonon line (ZPL) at 738 nm was recorded at all temperatures under 488 nm laser excitation. In particular the thermally induced shift of the ZPL was found promising for optical temperature sensing in the near infrared spectral range at biomedically relevant temperatures.

Published: December 2018

Background and objectives
Nontargeted metabolomics can measure thousands of low-molecular-weight biochemicals, but important gaps limit its utility for biomarker discovery in CKD. These include the need to characterize technical and intraperson analyte variation, to pool data across platforms, and to outline analyte relationships with eGFR.

Design, setting, participants, & measurements
Plasma samples from 49 individuals with CKD (eGFR<60 ml/min per 1.73 m2 and/or ≥1 g proteinuria) were examined from two study visits; 20 samples were repeated as blind replicates. To enable comparison across two nontargeted platforms, samples were profiled at Metabolon and the Broad Institute.

Results
The Metabolon platform reported 837 known metabolites and 483 unnamed compounds (selected from 44,953 unknown ion features). The Broad Institute platform reported 594 known metabolites and 26,106 unknown ion features. Median coefficients of variation (CVs) across blind replicates were 14.6% (Metabolon) and 6.3% (Broad Institute) for known metabolites, and 18.9% for (Metabolon) unnamed compounds and 24.5% for (Broad Institute) unknown ion features. Median CVs for day-to-day variability were 29.0% (Metabolon) and 24.9% (Broad Institute) for known metabolites, and 41.8% for (Metabolon) unnamed compounds and 40.9% for (Broad Institute) unknown ion features. A total of 381 known metabolites were shared across platforms (median correlation 0.89). Many metabolites were negatively correlated with eGFR at P<0.05, including 35.7% (Metabolon) and 18.9% (Broad Institute) of known metabolites.

Conclusions
Nontargeted metabolomics quantifies >1000 analytes with low technical CVs, and agreement for overlapping metabolites across two leading platforms is excellent. Many metabolites demonstrate substantial intraperson variation and correlation with eGFR.
Effect of a Medical Student-Led Curriculum on Teen Health Knowledge and Intentions: An Evaluation of the MiHealth Pilot Program
Authors: Brown Kathryn S. , Meixner Kaitlin A. , DeBenedictus Christina M. , Riley Margaret A. 
Published: December 2018

Introduction: Adolescents are often thought of as a healthy population, however, they routinely engage in high-risk behaviors that can lead to health problems. Medical students designed MiHealth, a program in which medical students teach health lessons in the high school classroom to help address these behaviors.
Methods: A series of six lessons were created and implemented in the classroom for this pilot study focused on sexual health, intimate partner violence, mental health, smoking and marijuana, nutrition, and physical fitness. High school students in grades nine through twelve at a public high school in southeast Michigan receiving the MiHealth curriculum (N=52) or the standard health education curriculum (N=61) were surveyed on health knowledge, attitudes, and intentions before and after the program.
Results: Six weeks after program completion, high school students who received the MiHealth curriculum scored significantly higher on health knowledge (P=0.007), and expressed significantly healthier attitudes and intentions toward risk behavior compared to controls (P=0.025). Among individual themes, MiHealth resulted in significant knowledge gains in sexual health (P=0.001) and mental health (P&lt;0.025), and significantly healthier attitudes regarding sexual health (P=0.047), nutrition (P=0.040), and smoking and marijuana (P=0.012).
Conclusions: MiHealth demonstrated promising improvements in health knowledge retention and attitude changes in adolescents 6 weeks after program completion. An interactive curriculum targeting key adolescent health topics given by near-peer medical student educators may provide benefits beyond traditional high school health curricula.

Latin American armed humanitarianism in Haiti and beyond
Authors: Hirst Monica 
Published: December 2018

MINUSTAH represents a benchmark in the link between global securitization and humanitarian practices in Latin America and the Caribbean. Regional military responsibilities in Haiti turned useful to improve and expand capabilities employed in international humanitarian crisis. Engagement in natural disaster has been the dominating terrain in which military humanitarian action takes place in Latin America and the Caribbean. Military presence in Haiti has also contributed for experimentation in the fight against organized crime and gangs, a growing concern on the radar of international humanitarian organizations and actors. Armed humanitarianism in the region has benefitted from ties with the US, particularly the South Command, and with the UN System, particularly the DPKO. Domestic and international involvement in humanitarian assistance has become major topic in regional intra-military initiatives, stimulated by exchange of new expertise and the expansion of teamwork programs. Simultaneously, armed humanitarianism has amplified the spectrum of civil-military relations by broadening interaction with local population and organizations in different parts of Latin America and the Caribbean. Yet, armed humanitarian is controversial in the region in face of its implication for human rights protection and the strength of democratic institutions. This text intends to trace a middle ground around military and humanitarian studies conceptualization by interlacing the concepts of postmodern military and armed humanitarianism. It parts from the assumption that both concepts, while focusing on different objects, may knit well to explain post-MINUSTAH Latin American military developments.

Authors: Chen Chi-Ya , Elarbi Mustafa , Ragle Claude A. , Fransson Boel A. 
Published: December 2018

Abstract
OBJECTIVE To develop and evaluate a high-fidelity simulated laparoscopic ovariectomy (SLO) model for surgical training and testing.
DESIGN Evaluation study.
SAMPLE 15 veterinary students (novice group), 5 veterinary surgical interns or residents (intermediate group), and 6 veterinary surgeons (experienced group).
PROCEDURES Laparoscopic surgery experience was assessed by questionnaire and visual analog scales. Basic laparoscopic skills were assessed with a commercial training model. A commercial canine abdomen model was customized with a high-fidelity simulated canine female genital tract. Each subject's SLO performance (laparoscopic entry, dissection along marked planes, and left ovariectomy) was evaluated by measurement of surgical time and errors (splenic puncture and deviation from dissection marks) and with global and operative component rating scales. Construct and concurrent validity were assessed by correlation of SLO results with self-estimated measures of experience level and with basic laparoscopic skills test results, respectively. Face validity was assessed with a questionnaire completed by intermediate and experienced group participants.
RESULTS 13 participants (3/15, 5/5, and 5/6 in the novice, intermediate, and experienced groups, respectively) completed SLO within the preset time. No difference in errors was found among groups. Completion time was significantly correlated with self-estimated experience level (r = −0.626), confirming construct validity, and with basic laparoscopic skills scores (r = −0.552) and global (r = −0.624) and operative component (r = −0.624) rating scale scores, confirming concurrent validity. Overall mean face validity score was low (64.2/100); usefulness of the model for surgical training received the highest score (8/10).
CONCLUSIONS AND CLINICAL RELEVANCE Results suggested the SLO model may be a useful surgical training tool. Further studies are needed to confirm usefulness of the model in veterinary laparoscopy training.
Thermal inactivation kinetics of Aspergillus oryzae β-galactosidase in concentrated lactose solution
Authors: Illeová Viera , Polakovič Milan 
Published: December 2018

Abstract
Thermal inactivation of a commercial β-galactosidase from Aspergillus oryzae in a 300 g/L lactose solution was studied in the temperature range of 65–75 °C. Lactose exhibited a stabilisation effect when similar inactivation rates as those in lactose solution were observed in a lactose-free solution at temperatures lower by 5°C. Inactivation process in the lactose solution was biphasic. A kinetic model based on the Lumry-Eyring mechanism was proposed and successfully verified. Estimated activation energy values were very different. Rather high activation energy values of the forward reactions were responsible for both the significant change of rate constants and the rate-controlling reaction with temperature. For these two reasons, an increase of the operational lifetime of the enzyme from 7 days at 60 °C to 580 days at 55 °C was predicted.
Fast nonlinear model predictive control of a chemical reactor: a random shooting approach
Authors: Bakaráč Peter , Kvasnica Michal 
Published: December 2018

Abstract
This paper presents a fast way of implementing nonlinear model predictive control (NMPC) using the random shooting approach. Instead of calculating the optimal control sequence by solving the NMPC problem as a nonlinear programming (NLP) problem, which is time consuming, a sub-optimal, but feasible, sequence of control inputs is determined randomly. To minimize the induced sub-optimality, numerous random control sequences are selected and the one that yields the smallest cost is selected. By means of a motivating case study we demonstrate that the random shooting-based approach is superior, from a computational point of view, to state-of-the-art NLP solvers, and features a low level of sub-optimality. The case study involves a continuous stirred tank reactor where a fast multi-component chemical reaction takes place.
The Role of microRNA-15A in the Development of Prostate Cancer – Effects on Cell Proliferation and Pro-Inflammatory Signalling
Authors: Apostolova A. , Sezer L. , Hayrabedyan S. , Todorova Kr. 
Published: December 2018

Abstract
Worldwide prostate cancer is the second leading cause of cancer death among men after lung cancer. MicroRNAs are non-coding, endogenous RNAs and they play a role in tumorigenesis, RNA silencing and post-transcriptional regulation of gene expression. In this study we have investigated microRNA-15a impact on transcription factors cMYB and ETS1 in prostate-carcinoma cell line PC3. The PC3 cells were transfected with a synthetic analogue and inhibitor of microRNA-15a. The study was performed using reverse transcription polymerase chain reaction and flow cytometry methods for assessing the transcript and protein levels of cMYB and ETS1, NFκB stable reporter live cell line. Statistical analysis was performed using One–way ANOVA test. We found that cMYB and ETS1 are up-regulated by the synthetic analogue of microRNA-15a at the transcription and protein level. Transfection with microRNA-15a mimic resulted in NFκB transcription factor activation as found by using the live cell reporter system. There was some opportunistic activity exhibited by the synthetic inhibitor, but less pronounced. Our data suggest that microRNA-15a could participate in prostate cancer progression by modulating cell proliferation and pro-inflammatory signaling and paves a way for further in-depth investigation of the gene regulatory networks underneath.

Authors: Pospieszyńska Aleksandra , Koprowski Marcin , Przybylak Rajmund 
Published: December 2018

Abstract
The aim of the studies was to evaluate the usefulness of the microscopic features of wood in characterising the climatic conditions of a period for which only proxy data are available. Samples were taken from historical wood from Koronowo collegiate church and from a living Scots pine tree growing in the Toruń-Wrzosy site. All measurements were performed using ImageJ software. The dendroclimatological analysis was carried out in the program DendroClim2002. The results show a correlation between the microscopic features of wood and climatic conditions. For the period 1951–2000 the maximum optical density of pine wood depends on average May air temperature and June precipitation, with correlation coefficients of −0.32 and −0.29, respectively. A similar correlation was found for mean maximum and minimum temperatures in May; -0.35 and -0.37, respectively. Additional correlations between selected meteorological elements and the maximum optical density of the wood were found using 30-year moving averages and moving intervals.
Botching Human Factors in Cybersecurity in Business Organizations
Authors: Nobles Calvin 
Published: December 2018

Abstract
Human factors remained unexplored and underappreciated in information security. The mounting cyber-attacks, data breaches, and ransomware attacks are a result of human-enabled errors, in fact, 95% of all cyber incidents are human-enabled. Research indicates that existing information security plans do not account for human factors in risk management or auditing. Corporate executives, managers, and cybersecurity professionals rely extensively on technology to avert cybersecurity incidents. Managers fallaciously believe that technology is the key to improving security defenses even though research indicates that new technologies create unintended consequences; nonetheless, technological induced errors are human-enabled. Managers’ current perspective on the human factors problem information security is too narrow in scope and more than a training problem. The management of complex cybersecurity operations accompanied by mounting human factor challenges exceeds the expertise of most information security professionals; yet, managers are reluctant to seek the expertise of human factors specialists, cognitive scientists, and behavioral analysts to implement effective strategies and objectives to reduce human-enabled error in information security.
The Evolution of Silicosis into Massive Pulmonary Fibrosis — Case Series
Authors: Székely-Vass Enikő , Szász Zsuzsánna , Horváth Gyopár , Hozoi Mădălina 
Published: December 2018

Abstract
Silicosis is one of the oldest occupational diseases, known since the time of Hippocrates, and the diagnosis can be established after a latency time of more than 10 years after exposure cessation. In some cases of chronic silicosis, the disease can progress slowly, evolving over several decades, but it can also evolve into massive pulmonary fibrosis, also known as accelerated silicosis. Furthermore, in extremely rare cases, the disease can present a rapid progression into acute silicosis or silicoproteinosis. The present article gives a deeper view into silicosis and secondary massive progressive pulmonary fibrosis, as well as the difficulties encountered in the management of such patients. We present two different but similar cases that underline the importance of a precise diagnosis, pointing out the long latent period after the exposure to silicon-dioxide, more than 15 years in both cases. This accelerated form of silicosis associated with massive pulmonary fibrosis progressed in 2 years into respiratory failure in both cases.
