Authors: Safonov K V , Zolotarev V V , Derben A M 
Published: May 2020

Abstract
Game tasks are vulnerable to methods of obtaining benefits based on the results of attacks on game resources. In such conditions, it is critical to determine, monitor and evaluate the possibility of such attacks. It is also advisable to select methods to prevent them in advance, constructing the gaming environment accordingly.
The paper describes various types of attacks on the gaming environment, its vulnerable components. Some possibilities for building gaming environment were shown. To improve the architecture of the gaming environment, identify possible channels of key information leakage, game theory methods were chosen. The analysis was performed and the possibility of predicting the attack on game resources for a certain type of gaming environment was shown.
For a distributed multiplayer security awareness game based on a real case, the estimates for the selected types of attacks are shown, the attacker’s selection criteria for the attack are calculated, and countermeasures are proposed. The article presents the results of two computational experiments with minor differences in the network infrastructure and the stored amount of game key information.
The results of the modelling of the main types of threats completely coincided with the obtained empirical data. The results shown can be used to evaluate various types of information security strategies in case of limited resources. The application of the approach is possible in various gamified media, including additional restrictions.

Abstract
The article studies the issues of increasing the quality of the surface and structure of a current-carrying skin layer in the small-section waveguide channels. We offer a promising technique of anodic abrasive polishing, which allows to remove anodic films from a machinable surface, activate and polish microroughnesses. We have developed the flow-chart of anodic abrasive polishing of small-section channels and undertaken a study. The process of anodic abrasive polishing can ensure the high quality of soft materials without impregnation of a machinable surface, as well as the high quality of hard materials with fine finish to Ra 0,04 micrometers keeping the original accuracy and structure of a current-carrying skin layer. We have presented a model and some recommendations how to perform anodic abrasive polishing.

An assessment of the condition of the Igarskaia Protoka on the Yenisei in 2018: side-scan sonar imagery interpretations and bathymetry
Authors: Goncharov A E 
Published: May 2020

Abstract
For almost eighty years, the town of Igarka on the Yenisei River had been an important timber industry center and seaport on the Northern Sea Route. Since the early 2000s, however, the town and its economy fell into decline resulting in the termination of timber export and, consequently, maritime navigation. In September 2018, a team of researchers from Reshetnev Siberian State University of Science and Technology, headed by the author of this paper conducted a side-scan survey of the Igarskaia Protoka, which had been the port’s harbor, in order to access the current state of its aquatic environment. This paper describes some preliminary results of this investigation, which is the first study of the underwater environment of this particular body of water.

Synthesis, DFT calculation, DNA-binding, antimicrobial, cytotoxic and molecular docking studies on new complexes VO(II), Fe(III), Co(II), Ni(II) and Cu(II) of pyridine Schiff base ligand
Authors: AlZamil Noura O 
Published: May 2020

Abstract
A new H2L ligand (6, 6′-(pyridine-2, 6-diylbis(azan-1-yl-1-ylidene))bis(methan-1-yl-1-ylidene)bis(2-ethoxyphenol) was obtained from the reaction of 2, 6- diamino pyridine and 3- ethoxy salicyaldehyde in 1:2 molar ratio and fully characterized using elemental analyses and spectroscopic tools. The reaction of a ligand with the different metal salts yields five new complexes CuL, CoL, NiL, FeL, and VOL. The new complexes were identified according to the results of elemental analyses, IR and UV–vis spectra, magnetic moment, molar conductance and thermal analyses (TGA). From the conductivity data, it is deduced that all complexes are non-electrolytes. FT-IR spectra displayed that the Schiff base ligand coordinated to the metal ions in a manner with ONNO donor sites, the nitrogen atom of the pyridine ring, the nitrogen of one azomethine group and two oxygen atoms of the two phenolic OH groups. The results of electronic spectra and magnetic susceptibility confirmed octahedral geometry of FeL complex and square pyramidal geometry for CoL, CuL and VOL and square planar for NiL. The electronic structure of H2L ligand and its complexes were investigated theoretically at the DFT-B3LYP-311 G** level of the theory. FT-IR spectra established the involvement of pyridine nitrogen in the coordination process. The presence of coordinated water molecules inside the coordination sphere of the complexes CoL, CuL and FeL are supported by TGA studies. The antimicrobial activities of the ligand and its complexes were determined against two Gram-positive bacteria (B. subtitles and S. aureus) and two Gram-negative (E. coli and P. vulgaris) and two fungus (Candida albicans and Aspergilla’s fumigates). The results showed that the complexes behaved as better antimicrobial agents than the ligand, VOL complex shows exceptional antimicrobial efficacy. The order of increasing the antibacterial and antifungal potency is H2L < NiL < CuL < CoL < FeL < VOL. The binding of the complexes with CT-DNA was followed using electronic absorption, viscosity and gel-electrophoresis measurements. These studies confirmed that the complexes bind to CT-DNA through a groove binding mode with certain affinities (Kb = 6.25 × 105, 5.50 × 105, 3.20 × 105, 2.50 × 105 and 1.52 × 105 for CuL, FeL, VOL, NiL, and CoL respectively). Moreover, cytotoxic effect against hepatocellular carcinoma cell line (HEP-G2) was screened. The IC50 values of the ligand and complexes suggest that the compounds possess very good cytotoxic activity and follow the order: CuL >FeL>VOL>NiL>CoL > H2L. These results strongly agree with results of binding constant of CT-DNA with different metal complexes.

Published: May 2020

Abstract

Europe faces a situation in which the photonics industry is growing and needs more well-prepared
professionals to support its growth and innovation potential. Addressing this
pressing need requires engaging all photonics stakeholders to increase the visibility of the
outstanding professional opportunities of photonics and provide the future workforce with
tools to increase their employability.

CARLA, a new European funded project, aims to create a novel, rigorous and tested
instrument to address this need at the source. It will develop a model for European photonics
career camp −a reproducible 2-day intense, multi-format event− that 1) obtains coordinated
input from all stakeholders, 2) encourages STEM university students, PhD students and
young postdocs to pursue a career in photonics and 3) can be replicated by other
organisations. CARLA will create a robust, competitive and sustainable career camp that will
be tested on 11 occasions during the 2020–21 period, solidifying a ready-to-replicate camp
model. It will incorporate the dimensions of industry, academia, innovation, entrepreneurship,
and employability, putting special attention on empowering diversity, both within the camps
and in the future photonics workforce.

Sustainability of the model will be ensured through the creation of a virtual careers in
photonics hub that will support the photonics community at large during and beyond
CARLA, and develop a comprehensive handbook to facilitate camp replication. With the
promotion of diversity serving as one of the cornerstones in the design and implementation of
CARLA, the project will furthermore translate lessons learned in the camps into an
“Empowering Diversity in Photonics” guide applicable to future camps and the photonics
community in general.
Facile fabrication of nanocomposites by modified carbon black loading with magnetite nanoparticles for fast removal of cadmium ions
Authors: Xiao Wangchuan , Li Meiyong , Su Zhizhong , Zhao Yan 
Published: May 2020

Abstract
Magnetic nanomaterials have unique advantages in heavy metal ions absorption because of their large specific surface area and easy magnetic manipulation. Carbon nanotube or graphene loaded with magnetite nanoparticles (MNPs) have been utilized to fabricate absorbents with both high absorption capacity and fast magnetic capture. Herein, cheap commercial carbon black was used as a substitute for expensive carbon nanotube or graphene to fabricate nanocomposites (CB-MNP) by modified carbon black loaded with superparamagnetic MNPs. The fabrication process is accomplished by two steps. Carbon blacks (CB) were modified by nitric acid to produce a large number of carboxyl groups on the surface and make stable aqueous dispersion. Subsequently, CB-MNPs with high water stability and fast magnetic response were facilely prepared by iron precursors (the ratio of ferrous to ferric is 1:2) added into the above CB dispersion and tuned pH = 10, finally added polyacrylic acid solution under sonication. Modified CB and CB-MNPs were characterized by transmission electron microscope (TEM), dynamic laser scattering (DLS), thermogravimetric analysis and so on. Water stability and magnetic response can be controlled by changing the proportion of CB and iron precursor. As a proof-of-concept, CB-MNPs were used for absorption removal of cadmium ions. Excellent performance was demonstrated with the removal efficiency of 71.41% and removal capacity of 39.99 mg · g−1 at the initial concentration of Cd2+ as 5 × 10−5 mol · l−1. The effects of initial concentration of Cd2+, pH value and interfering anion ions were also investigated and the results indicate the potential application of CB-MNP in fast removal of heavy metal ions.

Authors: Wu Qingyun , Cao Liemao , Ang Yee Sin , Ang Lay Kee 
Published: May 2020

Abstract
Inspired by superior gas sensing properties of PtSe2 monolayer and tunable gas sensing properties of Janus MoSSe monolayer, we study the gas sensing properties of the Janus PtSSe monolayer for CO, CO2, H2O, NH3, NO and NO2 gas molecules using first-principles density functional calculations. We calculate adsorption height and adsorption energies of the gas molecules to assess the adsorption strength of the gas molecules. Then the charge transfer from PtSSe to gas molecules is evaluated. We also investigate the effects of strain and external electric field on the gas sensing properties of Janus PtSSe monolayer. We finally reveal the origin of the superior gas sensing properties from projected density of states analysis. Our results suggest that the Janus PtSSe monolayer is a promising gas sensor with superior and tunable sensing properties.
Acute Bidirectional Relations Between Affect, Physical Feeling States, and Activity-Related Behaviors Among Older Adults: An Ecological Momentary Assessment Study
Authors: Hevel Derek J , Dunton Genevieve F , Maher Jaclyn P 
Published: May 2020

Abstract

Background
The majority of older adults are physically inactive; therefore, strategies are needed to effectively promote sustained engagement in physical activity.

Purpose
This study was designed to investigate acute bidirectional relationships between affective and physical feeling states and activity-related behaviors among older adults in the context of everyday life using Ecological Momentary Assessment (EMA).

Methods
Older adults (n = 103, Mage = 72, Range: 60–98) participated in a 10-day study where they completed up to 6 smartphone-based EMA prompts/day. At each EMA prompt, participants reported their current positive and negative affect and physical feeling states. Participants wore an activPAL accelerometer to measure time spent standing and time spent stepping before and after the prompt. Separate multilevel random coefficient linear and logistic regression models examined these bidirectional relationships.

Results
On occasions when older adults engaged in more standing and more stepping than was typical for them in the 15 and 30 min prior to the EMA prompt, they tended to report greater feelings of energy at the prompt. On occasions when older adults reported greater feelings of energy than was typical for them, they engaged in more standing and more stepping in the 15 and 30 min following the EMA prompt. Positive and negative affect was unrelated to activity-related behaviors.

Conclusions
Feelings of energy appear to be strongly linked to activity-related behaviors in older adults; however, this was not the case for positive or negative affect. These findings may have implications for optimal delivery of just-in-time intervention context based on affective states or current behaviors.

Published: May 2020

Abstract

Purpose
After community transmission of the novel virus that causes coronavirus disease 2019 (COVID-19) was detected in the State of Washington in February 2020, innovative measures, such as telehealth appointments, were needed to safely continue to provide optimal pharmaceutical care for patients with chronic conditions and cancer.

Summary
Prior to the COVID-19 pandemic, federal regulations limited the scope of telehealth pharmacist services. However, enactment of the Coronavirus Preparedness and Response Supplemental Appropriations Act, followed by guidance by the Centers for Medicare and Medicaid Services and the Department of Health and Human Services, allowed currently credentialed providers (including pharmacists) to continue to provide patient care services via telehealth with fewer restrictions. Our health system has numerous credentialed pharmacists across multiple ambulatory care clinics. In this article, we highlight our process of expediting the implementation of telehealth services. This process included obtaining authorization for the credentialed pharmacists to provide telehealth services, completion of training modules, implementation of new technology platforms, development of new workflows, and utilization of resources for providers and patients to facilitate successful completion of telehealth visits. We also highlight the consent and documentation components crucially important to the telehealth visit and share some of our successes, as well as identified limitations, in providing pharmacist services via telehealth.

Conclusion
In the setting of the COVID-19 pandemic, our institution was able to swiftly implement clinical pharmacist telehealth services for many patients, offering a safe and effective way to continue providing a high level of care. This article discusses our experience with and potential limitations of telehealth to assist other pharmacists seeking to implement and/or expand their telehealth services.
DeepCDA: deep cross-domain compound–protein affinity prediction through LSTM and convolutional neural networks
Authors: Abbasi Karim , Razzaghi Parvin , Poso Antti , Amanlou Massoud , Ghasemi Jahan B , Masoudi-Nejad Ali 
Published: May 2020

Abstract

Motivation
An essential part of drug discovery is the accurate prediction of the binding affinity of new compound–protein pairs. Most of the standard computational methods assume that compounds or proteins of the test data are observed during the training phase. However, in real-world situations, the test and training data are sampled from different domains with different distributions. To cope with this challenge, we propose a deep learning-based approach that consists of three steps. In the first step, the training encoder network learns a novel representation of compounds and proteins. To this end, we combine convolutional layers and long-short-term memory layers so that the occurrence patterns of local substructures through a protein and a compound sequence are learned. Also, to encode the interaction strength of the protein and compound substructures, we propose a two-sided attention mechanism. In the second phase, to deal with the different distributions of the training and test domains, a feature encoder network is learned for the test domain by utilizing an adversarial domain adaptation approach. In the third phase, the learned test encoder network is applied to new compound–protein pairs to predict their binding affinity.

Results
To evaluate the proposed approach, we applied it to KIBA, Davis and BindingDB datasets. The results show that the proposed method learns a more reliable model for the test domain in more challenging situations.

Published: May 2020

AbstractBackgroundAn elevated serum C-reactive protein (CRP) level was observed in most patients with coronavirus disease 2019 (COVID-19).MethodsData for COVID-19 patients with clinical outcome in a designated hospital in Wuhan, China, were retrospectively collected and analyzed from 30 January 2020 to 20 February 2020. The prognostic value of admission CRP was evaluated in patients with COVID-19.ResultsOf 298 patients enrolled, 84 died and 214 recovered. Most nonsurvivors were male, older, or with chronic diseases. Compared with survivors, nonsurvivors showed significantly elevated white blood cell and neutrophil counts, neutrophil to lymphocyte ratio (NLR), systemic immune inflammation index (defined by platelet count multiplied by NLR), CRP, procalcitonin, and D-dimer and showed decreased red blood cell, lymphocyte, and platelet counts. Age, neutrophil count, platelet count, and CRP were identified as independent predictors of adverse outcome. The area under the receiver operating characteristic (ROC) curve (AUC) of CRP (0.896) was significantly higher than that of age (0.833), neutrophil count (0.820), and platelet count (0.678) in outcome prediction (all P &lt; .05). With a cutoff value of 41.4, CRP exhibited sensitivity of 90.5%, specificity of 77.6%, positive predictive value of 61.3%, and negative predictive value of 95.4%. CRP was also an independent discriminator of severe/critical illness on admission with an AUC (0.783) comparable to age (0.828) and neutrophil count (0.729) (both P &gt; .05).ConclusionsIn patients with COVID-19, admission CRP correlated with disease severity and tended to be a good predictor of adverse outcome.
