Bambusuril analogs based on alternating glycoluril and xylylene units
Authors: Lízal Tomáš , Šindelář Vladimír
Published: June 2019

The glycoluril monomer is a popular building block in supramolecular chemistry as it is used for the synthesis of versatile host molecules which can interact with cationic, anionic or neutral guest molecules. Here we present the design and synthesis of a new hybrid macrocycle containing glycoluril and aromatic units. The reaction afforded a mixture of macrocyclic homologues from which a two-membered macrocycle was isolated as the main product. Two disastereomers of the macrocycle were separated and characterized by means of NMR spectroscopy and X-ray crystallography. Conformational changes of these diastereomers were investigated using DFT models and variable-temperature NMR.

Authors: Tatina Madhu Babu , Mengxin Xia , Peilin Rao , Judeh Zaher M A
Published: June 2019

A convenient protocol was developed for the synthesis of 2,3-unsaturated C-, O-, N- and S-linked glycosides (enosides) using 20 mol % perflurophenylboronic acid catalyst via Ferrier rearrangement. Using this protocol, D-glucals and L-rhamnals reacted with various C-, O-, N- and S-nucleophiles to give a wide range of glycosides in up to 98% yields with mainly α-anomeric selectivity. The perflurophenylboronic acid successfully catalyzed a wide range of substrates (both glucals and nucleophiles) under very mild reaction conditions.

Published: June 2019

Sacred Natural Sites are relevant for biodiversity conservation, as in the case of forest sites that, across centuries, developed old growth structures and are now crucial for the conservation of epiphytic lichens and other specialized forest organisms. In this study, we investigated the epiphytic lichen flora of a small forest patch included in the Majella National Park (Abruzzo), whose old growth features and naturalness reflect its long lasting spiritual role that perfectly fits with the concept of Sacred Natural Site. Results revealed that the “Bosco di Sant’Antonio” hosts a rich and interesting epiphytic lichen flora, thus indicating the potential of this Sacred Natural Site for lichen conservation. Fifty-six species were found including two species newly recorded in Abruzzo, two red-listed species, and the sensitive species Lobariapulmonaria. This study corroborates the hypothesis that sacred forest sites are relevant for the conservation of specialized epiphytic lichens. In particular, in the Italian forest landscape where old-growth stands are practically absent, sacred forest sites may provide unique old-growth structures and buffer anthropogenic disturbance.

Early Clinical Outcome of Lumbar Spinal Fixation With Cortical Bone Trajectory Pedicle Screws in Patients With Osteoporosis With Degenerative Disease
Authors: Liu Lei , Zhang Shaodong , Liu Guozhen , Yang Baolin , Wu Xiaotao
Published: June 2019

This cohort study aimed to elucidate early surgical outcomes after midline lumbar fusion (MidLIF) with cortical bone trajectory (CBT) screw fixation compared with transforaminal lumbar interbody fusion (TLIF) using traditional pedicle screw (TPS) fixation for lumbar degenerative disease (LDD) in patients with osteoporosis. The authors randomly assigned 70 patients with osteoporosis who had LDD at 1 or 2 adjacent vertebral levels to undergo either MidLIF with CBT (CBT group) or TLIF with TPS fixation (TPS group) from February 2015 to March 2016. Pre- and postoperative lumbar Japanese Orthopaedic Association (JOA) scale scores were assessed and radiographic measurements on dynamic plain radiographs and computed tomography images were analyzed. The final data analysis included 31 patients in the CBT group (mean age, 73.42±6.74 years; t-score, −2.94±0.75) and 32 patients in the TPS group (mean age, 74.84±5.37 years; t-score, −2.92±0.66). Mean JOA score improved significantly in both groups, although no intragroup differences of JOA score improvement were found at the latest follow-up evaluation (
P
>.05). In addition, significantly higher rates of screw loosening (28.13% vs 6.5%,
P
=.03) and the amount of subsidence (3.01±0.52 vs 2.49±0.45 mm,
P
=.02) were found in the TPS group. Rate of radiographic fusion of both groups showed no statistical difference. Both groups of patients achieved a similar rate of radiographic fusion at the 1.5-year follow-up and experienced similar intra- or postoperative complications and postoperative recovery. The MidLIF with CBT screw fixation for short-level lumbar fusion in patients with osteoporosis provided improvement of clinical symptoms comparable to that of TLIF using traditional TPS fixation. In addition, statistically significant lumbar stability was found in the CBT group compared with the TPS group. [

Comparison of Multicolored Spot Reflection Topographer and Scheimpflug-Placido System in Corneal Power and Astigmatism Measurements With Normal and Post-refractive Patients
Authors: Lu Weicong , Miao Yaxin , Li Yue , Hu Xiuli , Hu Qingjie , Huang Jinhai
Published: June 2019

PURPOSE:

To evaluate the repeatability of corneal power and astigmatism derived by a novel multicolored spot reflection topographer system (Cassini; i-Optics, Hague, Netherlands) and compare its agreement with a Placido-Scheimpflug system (Sirius; Costruzione Strumenti Oftalmici, Florence, Italy) in normal and post-refractive patients.

METHODS:

This prospective study comprised patients who underwent myopic excimer laser refractive surgery (96 eyes) and normal patients (102 eyes). Each patient was measured three times with the Cassini and Sirius. The simulated keratometry (SimK), total corneal power (TCP), and astigmatism were recorded. The repeatability was assessed by one-way analysis of variance. The paired
t
test was used to compare the differences, whereas the agreement was evaluated by Bland–Altman analysis.

RESULTS:

All parameters obtained by the Cassini demonstrated high repeatability, except for total corneal astigmatism (TCA) in the post-refractive group. The intraclass correlation coefficients of all parameters were greater than 0.85, the correlation of variation values was less than 0.55%, and the test–retest repeatability was less than 0.85 diopters (D). The paired
t
test showed significant differences in steep keratometry, astigmatism, TCP, and TCA in the normal group and in J
0
, TCP, and TCA in the post-refractive group. The 95% limits of agreement (LoA) in the normal group demonstrated good agreement, except for TCP. Only J
0
and J
45
of astigmatism and TCA remained narrow for 95% LoA in the post-refractive group.

CONCLUSIONS:

These results suggested that the Cassini provided high repeatable measurements in corneal power and astigmatism, except the TCA of post-refractive patients. The parameters could be used interchangeably in normal patients, except for TCP, whereas only J
0
of astigmatism and J
0
, J
45
of TCA showed good agreement in post-refractive patients.

Long-term Effects After Pediatric LASIK for Anisometropic Amblyopia in Two Patients
Authors: Zhou Siwei , Dhaliwal Deepinder K.
Published: June 2019

PURPOSE:

To report long-term follow-up of two pediatric patients who underwent laser in situ keratomileusis (LASIK) for myopic anisometropic amblyopia.

METHODS:

Case series.

RESULTS:

Two patients who underwent unilateral LASIK in 1999 for anisometropic amblyopia were clinically assessed 16 years after their initial procedure with visual acuity testing, refraction, stereopsis, axial length, corneal topography, slit-lamp examination, and quality of life assessment. Patients had stable corrected distance visual acuity, balanced refraction, improved stereopsis, and good visual quality of life. Corneal topography showed a mildly decentered ablation bed with no evidence of ectasia.

CONCLUSIONS:

LASIK in the pediatric population requires special considerations, including fixation and centration issues, microkeratome selection, and refractive endpoint. The two patients were found to have stable corneal topography, visual acuity, and stereopsis 16 years after initial treatment.

Digital Entrepreneurship Education - The Role of MOOCs
Authors: Vorbach Stefan , Poandl Elisabeth , Korajman Ines
Published: June 2019

Digital entrepreneurship has gained more attention in theory and practice in recent years. Among other forms of digital entrepreneurship education, MOOCs (mas-sive open online courses) are one of the strongest trends and influence the content and flow of teaching and learning. The paper contributes to a better understanding of the necessary skills, opportunities and risks arising from the use of MOOCs as a new way of teaching entrepreneurship. It empirically examines challenges and drivers for the use of MOOCs as a novel pedagogical concept. The results show that a lack of self-discipline to complete a MOOC and a lack of interaction with others are the main obstacles compared to lectures with compulsory univer-sity attendance. However, the results also show that MOOCs are flexible in time and space and can thus facilitate the accessibility of education, especially entre-preneurial education.
Using Online Discussions to Develop the Entrepreneurial Mindset in Environmental Engineering Undergraduates: A Case Study
Authors: Bosman Lisa , Duval-Couetil Nathalie , Mayer Brooke , McNamara Patrick
Published: June 2019

Entrepreneurship is an important aspect of the U.S. and global economy. As such, developing an entrepreneurial mindset is crucial for both engineering students and practicing engineers. The purpose of this paper is investigate the role of online discussions, as a pedagogical approach, in the development of the entrepreneurial mindset, and explore a variety of approaches to assess student learning outcomes. Online discussions prompts were created for environmental engineering courses using the Kern Engineering Entrepreneurial Network (KEEN) framework. The framework proposes that an entrepreneurial mindset can be fostered in students by promoting curiosity, encouraging connections, and creating value. This paper describes the methodology and rationale that served as the foundation for this exploratory study. Examples are provided for online discussion prompts developed and administered in two different environmental engineering undergraduate courses: Introduction to Environmental Engineering (three credit, undergraduate, online course offered during two different summer sessions) and Seminar in Environmental Engineering (one credit, undergraduate level, face-to-face course offered during one semester). Quantitative and qualitative methods were used to analyze and assess potential impacts of online discussion prompt use. The findings provide lessons learned for applying the KEEN framework in an engineering classroom via online discussions.

Multiparticle Models of Brownian Dynamics for the Description of Photosynthetic Electron Transfer Involving Protein Mobile Carriers
Authors: Riznichenko Galina Yurjevna , Kovalenko Ilya
Published: June 2019

The article presents a review of modeling the interaction of photosynthetic proteins using the multiparticle Brownian dynamics method developed at the Department of Biophysics, Biological Faculty, Lomonosov Moscow State University. The authors used multiparticle Brownian methods coupled to molecular dynamic simulations to reveal the role of electrostatic interactions and conformational changes in the transfer of an electron from the cytochrome complex to the molecule of the mobile carrier plastocyanin in plants, green algae, and cianobacteria. Taking into account the interior of photosynthetic membrane, they developed the model, combining events of protein diffusion along the thylakoid membrane, electrostatic interactions between proteins and the proteins with the membrane charges, formation of a multiprotein complex, electron transfer within a complex, and complex dissociation. They have also developed multiparticle models of competitive interactions between electron acceptors ferredoxin.
Cash Note With High Performance Security
Authors: Srinivasu Lingamallu Naga , Rao Kolakaluri Srinivasa
Published: June 2019

Rapid creation of fake notes affects the financial status, the value of the currency, unemployment rate, etc. In this paper, a cash note is generated with high level security features – it has specific serial number which will be encoded in that cash note with a procedure. Even if a person encodes the serial number in a fake cash note, the decoder will identify it as a fake one. If serial number and cash denomination at the decoding match with those of encoded cash note, then that note can be treated as genuine one. Otherwise it can be considered as a fake one. First, each digit of the serial number on the cash note is converted into binary number with a procedure and can be located beside the count indicator. Every cash note has some denomination and its decimal value is converted into binary number which can be kept beside the mode indicator. The count indicator and mode indicator are generated in the course of operation. The obtained encoded binary number is divided into codewords of 8 bits each. Each bit of code word is arranged at random locations in the cash note.
Looking Into the Binary Interactome of Enterobacteriaceae Family of Bacteria
Authors: Namboodiri Saritha , Giuliani Alessandro
Published: June 2019

Protein-protein interactions (PPIs) regulate most of the biological activities within a cell. A set of pairwise PPIs in seven genera of bacterial pathogens (Salmonella, Escherichia, Shigella, Yersinia, Klebsiella, Photorhabdus, and Pantoea) of Enterobacteriaceae family was analysed. At genotypic level, the correlation coefficient analysis of the mutation spectra of the ten sets of directly interacting protein partners in Escherichia coli recognised all the ‘interacting partners' in Escherichia coli. Extending the correlation analysis to include strains from the rest of the bacterial genera decreased the recognition efficiency providing quantitative evidence that binary interactome have incomplete superposition across species. At phenotype level, a reliable classification of bacterial pathogens was obtained by measuring PPI variations in terms of between phylogenetic distance correlation distances among ten sets of proteins partners. This forces us to rethink upon the possibility of PPI rewiring with a consequent change in physiological role of the same protein.

The research should be based on the possibility of quick access to information, interactivity and interaction of participants in search for information, elimination of temporal and spatial obstacles. Everything mentioned above requires the use of new research technologies, including blockchain technology. This technology allows solving the problems of collection and systematization of scientific data, access to it within the framework of project operation and implementation at any organization, and joint efforts of various structures. Data saved in blocks and stored on different servers can be accessed by different users. It reduces the cost of coordinating the actions of different users who want to obtain certain information. This article explores how blockchain technology is changing traditional methods of applied research in bioinformatics.
Dark and Deep Webs-Liberty or Abuse
Authors: Topor Lev
Published: June 2019

While the Dark Web is the safest internet platform, it is also the most dangerous platform at the same time. While users can stay secure and almost totally anonymously, they can also be exploited by other users, hackers, cyber-criminals, and even foreign governments. The purpose of this article is to explore and discuss the tremendous benefits of anonymous networks while comparing them to the hazards and risks that are also found on those platforms. In order to open this dark portal and contribute to the discussion of cyber and politics, a comparative analysis of the dark and deep web to the commonly familiar surface web (World Wide Web) is made, aiming to find and describe both the advantages and disadvantages of the platforms.
Social Media Networking and Tactical Intelligence Collection in the Middle East
Authors: Howells Karen
Published: June 2019

Social media platforms are commonly used as a way to gather intelligence information by intelligence organizations in many countries. The data available from social media networks has been instrumental in aiding the organisation of rebellious activities in a number of Middle East countries. This article features an overview of the use of social media platforms in facilitating civil unrest, leading to an in-depth depiction of the use of such platforms both in Israel and the Palestinian Territories. After analyzing the types of data collected by intelligence agencies in the region, a model for filtering social network data through the use of socialbots is suggested. Using artificial intelligence, it is possible to design, create and build socialbots that can scrutinize enemy or terrorist organisations' data output. Further programming would allow these socialbots to interact with a target and would be able to disseminate propaganda for the intelligence agencies.
Provably Secure Private Set Intersection With Constant Communication Complexity
Authors: Debnath Sumit Kumar
Published: June 2019

Electronic information is increasingly shared among unreliable entities. In this context, one interesting problem involves two parties that secretly want to determine an intersection of their respective private data sets while none of them wish to disclose the whole set to the other. One can adopt a Private Set Intersection (PSI) protocol to address this problem preserving the associated security and privacy issues. In this article, the authors present the first PSI protocol that incurs constant (p(k)) communication complexity with linear computation overhead and is fast even for the case of large input sets, where p(k) is a polynomial in security parameter k. Security of this scheme is proven in the standard model against semi-honest entities. The authors combine somewhere statistically binding (SSB) hash function with indistinguishability obfuscation (iO) and space-efficient probabilistic data structure Bloom filter to design the scheme.

Extant research indicates that professional law enforcement officers (LEOs) are generally no better than untrained novices at detecting deception. Moreover, traditional training methods are often less effective than no training at all at improving successful detection. Compared to the traditional training, interactive digital games can provide an immersive learning environment for deeper internalization of new information through simulated practices. VERITAS—an interactive digital game—was designed and developed to train LEOs to better detect reliable deception cues when questioning suspects and determining the veracity of their answers. The authors hypothesized that reducing players' reactance would mitigate resistance to training, motivate engagement with materials, and result in greater success at deception detection and knowledge. As hypothesized, LEOs playing VERITAS showed significant improvement in deception detection from the first to the second scenario within the game; and the low-reactance version provided the most effective training. The authors also compared various responses to the game between LEOs and a separate undergraduate student sample. Relative to students, findings show LEOs perceived VERITAS to be significantly more intrinsically motivating, engaging, and appealing as a deception detection activity.

The objective of study was to identify and describe the cognitive content of commercial Exergames through the evaluation of five experts in cognitive functions. The method used to delineate the relevance of the executive functions in Exergames involved the concordance between judges. Based on the evaluation of the experts, regarding the representativeness of the cognitive functions for each modality, 60% agreed moderately that logical reasoning was present in soccer. In athletics, logical reasoning in the launching of dart stands out (60%). In the long jump, 60% of the experts moderately agreed that logical reasoning is present, while in skiing 60% stated that participants used selective attention. In Tennis, 40% of experts agreed that cognitive flexibility is demonstrated. There was great agreement by the experts that the aquarium game involved the presence of selective attention (100%), except in the case of the winding stream. It is concluded that there is a representation of executive functions in the commercial Exergames analyzed.

The use of game mechanics and game structures when designing curriculums is gaining popularity in K-12 and higher education. More evidence is needed to determine the impact of game-based learning design on the student learning experience. This study used the IMMS instrument and user data to examine motivation within traditional courses and courses designed with game-based learning. The participants included 254 undergraduate students in two sections of the traditional course and two sections of the game-based learning course. The results showed that although students in all courses reported comparable motivation on the IMMS and similar time spent online, examination of user data indicated differences in effort persistence over the semester. Students in the GBL courses had a significantly higher number of interactions with content as compared to the traditional courses. This finding indicates that the leveling of content, adaptive release of optional content, and the ability to earn more points through a bank feature positively impacts effort persistence.
A Framework for Civil Registration in Developing Countries Based on Biometrics and ISO Standards
Authors: Musambo Lubasi Kakwete , Phiri Jackson
Published: June 2019

Most developing countries in Africa have civil registration processes with inherent challenges that inhibit their efficiency and accuracy. Attempts at modernization and improvement are on-going. In this article, a biometric framework that can be used to mitigate the challenges inherent in biometric data management for the civil registration system in Zambia is presented. The proposed framework presented is based on ISO models and adapted for most developing countries with low Information and Communication Technologies. A baseline study was undertaken to assess the understanding and appreciation of biometrics within the Zambian community and how this data might be stored or managed. A study of the Zambian civil registration business process has been undertaken and the authors propose an automated civil registration business process. Results obtained show that currently, Zambia does NOT have a biometric framework that supervises use of biometric data. The proposed model once adopted would form a secure framework for civil registration based on biometrics and ISO standards.

In recent times, microblogging sites such as Twitter have become popular communication platforms for exchanging information. From the point of view of individual user, a reasonably active Twitter user can easily get hundreds of microblogs (tweets) in his/her timeline every day. In addition, a large number of the tweets contain fundamentally the same information, because of retweeting and re-posting. These huge amounts of repetitive data may cause data over-burden for the users, and no user can effectively process so much data. In this situation, methodologies to manage the data over-burden should be developed. One of the effective methods for managing the data over-burden on Twitter is to cluster semantically similar tweets into groups, with the goal that a user may see just a couple of tweets in each group. In this work, various graph clustering approaches based on dimension reduction are proposed for clustering microblogs. Through experiments on several microblog datasets, the authors demonstrate that the proposed techniques perform better than several classical text clustering algorithms.

Published: June 2019

Each Android application requires accumulations of permissions in installation time and they are considered as the features which can be utilized in permission-based identification of Android malwares. Recently, ensemble feature selection techniques have received increasing attention over conventional techniques in different applications. In this work, a cluster based voted ensemble voted feature selection technique combining five base wrapper approaches of R libraries is projected for identifying most prominent set of features in the predictive modeling of Android malwares. The proposed method preserves both the desirable features of an ensemble feature selector, accuracy and diversity. Moreover, in this work, five different data partitioning ratios are considered and the impact of those ratios on predictive model are measured using coefficient of determination (r-square) and root mean square error. The proposed strategy has created significant better outcome in term of the number of selected features and classification accuracy.

Published: June 2019

Predictive touch technology aims to improve the usability and performance of in-vehicle displays under the influence of perturbations due to the road and driving conditions. It fundamentally relies on predicting and early in the freehand pointing movement, the interface item the user intends to select, using a novel Bayesian inference framework. This article focusses on evaluating facilitation schemes for selecting the predicted interface component whilst driving, and without physically touching the display, thus touchless. Initially, several viable schemes were identified in a brainstorming session followed by an expert workshop with 12 participants. A simulator study with 24 participants using a prototype predictive touch system was then conducted. A number of collected quantitative and qualitative measures show that immediate mid-air selection, where the system autonomously auto-selects the predicted interface component, may be the most promising strategy for predictive touch.
