Ultimate transformation: How will automation technologies disrupt the travel, tourism and hospitality industries?
Authors: Ivanov Stanislav 
Published: May 2019

Abstract
Companies from the travel, tourism and hospitality industry have started adopting robots, artificial intelligence and service automation technologies (RAISA) in their operations. Self-check-in kiosks, robotic pool cleaners, delivery robots, robot concierges, chatbots, etc., are used increasingly by tourism companies and transform the ways they create and deliver services. This paper investigates the impact of RAISA technologies on travel, tourism and hospitality companies – their operations, facilities design, marketing, supply chain management, human resource management, and financial management. The paper emphasises that in the future companies will divide into two large segments – high-tech tourism companies offering standardized cheap robot-delivered services, and high-touch companies, which rely on human employees.
Effect of Friction on Performance of Fiber-Reinforced Concrete in the ASTM C1550 Panel Test
Authors: Bernard Erik Stefan 
Published: May 2019

AbstractPanel and beam tests are widely used to assess the flexural performance of fiber-reinforced concrete (FRC). The performance data obtained in these tests is used for applications ranging from materials research to structural design and quality control. Designers that specify minimum levels of flexural performance for FRC when used in structural applications do this on the assumption that the results obtained from flexural performance tests represent the actual flexural performance of an FRC mixture. In reality, a considerable proportion of the apparent postcrack performance is attributable to friction at the supports. The result is that the postcrack flexural performance measured in tests may be considerably greater than the actual flexural performance of a given FRC mixture. The current research examines how friction at the supports under ASTM C1550, Standard Test Method for Flexural Toughness of Fiber Reinforced Concrete (Using Centrally Loaded Round Panel), round panel tests affects the apparent performance and variability in performance of FRC mixtures. The effect of friction was investigated by comparing results obtained using steel support plates of the type described in ASTM C1550 with results obtained using low-friction support plates. Twelve FRC mixtures were used containing a wide variety of dosages and types of fibers, thus resulting in a wide range of postcrack flexural performances. The results indicate that friction is responsible for about 12.5 % of the energy absorption or residual flexural strength obtained, but has a negligible influence on within-batch variability of test results.

Published: May 2019

Abstract
In this study, the effect of multi-walled carbon nanotubes (MWCNT) reinforcement on joint shear strength and microstructural development of tin-3.0silver-0.5copper (SAC305)/copper solder joint subjected to multiple reflow cycles was investigated. The MWCNT-reinforced SAC305 solder systems (SAC305-x MWCNT; x = 0.01, 0.05, 0.1, and 0.5 wt.%) were developed by a mechanical dispersion method. The microstructural, mechanical, and melting properties of SAC305 composite solders were evaluated as a function of different wt.% of MWCNT addition. The melting behavior of composite solders was analyzed using differential scanning calorimetry. The morphology and intermetallic compound growth at the solder joint interface were studied using scanning electron microscopy. The copper/solder/copper micro-lap-shear solder joint specimens reflowed for multiple reflow cycles were systematically characterized to evaluate the joint shear strength. The results showed that the reinforcement in the range of 0.01–0.05 wt.% of MWCNT resulted in the improvement of joint shear strength and better wettability compared to plain SAC305 solder alloy. Amongst all compositions analyzed, SAC305-0.05MWCNT nanocomposite suppressed the intermetallic compound layer growth effectively leading to improvement in the joint shear strength under multiple reflow cycles.

Published: May 2019

Abstract
Carbon materials are promising supports for heterogeneous catalysis compared to oxide supports, such as titania, alumina, mesoporous silica, and hydrotalcite, because of their stability and relative chemical inertness. Additionally, the unique surface structures of carbon supports help control the growth, aggregation, and uniformity of the catalytic nanoparticles (NPs) hybridized with them. However, the effect of carbon supports on these NP catalysts is not well understood, affecting the optimization of this type of catalysts. In this study, palladium-gold (Pd/Au) carbon composites were systematically investigated, and the most favorable carbon support was identified. Carbon-supported Pd/Au NPs have often been favored for catalytic hydrodehalogenation (HDH) of volatile organic compounds. Hence, this study uses trichloroethylene (TCE) as model contaminant to investigate the effects of four types of carbon supports—granular activated carbon (GAC), carbon black, graphite, and graphite nanoplates—on the formation of catalytic Pd/Au NPs and their correlations to HDH reactions. Each support was chosen based on a desirable quality: GAC has a large surface area and substantial absorption capabilities, carbon black has a high surface-area-to-volume ratio and good chemical stability, graphite is the most stable form of carbon with a layered structure and thermal stability, and graphite nanoplates have large surface areas with structural stability. Characterizations of these Pd/Au-carbon composites show different NP sizes on each support, with GAC and carbon black generating smaller NPs. The HDH results suggest GAC, carbon black, and graphite nanoplates composites generate fast reaction rates. However, when comparing particle size and surface area, Pd/Au-GAC composites generate the fastest TCE degradation, providing a bigger boost to HDH rates than other types of carbon supports. More advantageously, GAC is widely available commercially with relatively low cost, and its high surface area is enabled by its high porosity, making GAC the preferred carbon support for Pd/Au NP catalyst mass production.

Published: May 2019

Abstract
Signaling pathways can regulate biological responses by the transcriptional regulation of target genes. In yeast, multiple signaling pathways control filamentous growth, a morphogenetic response that occurs in many species including fungal pathogens. Here, we examine the role of signaling pathways that control filamentous growth in regulating adhesion-dependent surface responses, including mat formation and colony patterning. Expression profiling and mutant phenotype analysis showed that the major pathways that regulate filamentous growth [filamentous growth MAPK (fMAPK), RAS, retrograde (RTG), RIM101, RPD3, ELP, SNF1, and PHO85] also regulated mat formation and colony patterning. The chromatin remodeling complex, SAGA, also regulated these responses. We also show that the RAS and RTG pathways coregulated a common set of target genes, and that SAGA regulated target genes known to be controlled by the fMAPK, RAS, and RTG pathways. Analysis of surface growth-specific targets identified genes that respond to low oxygen, high temperature, and desiccation stresses. We also explore the question of why cells make adhesive contacts in colonies. Cell adhesion contacts mediated by the coregulated target and adhesion molecule, Flo11p, deterred entry into colonies by macroscopic predators and impacted colony temperature regulation. The identification of new regulators (e.g., SAGA), and targets of surface growth in yeast may provide insights into fungal pathogenesis in settings where surface growth and adhesion contributes to virulence.
Homolog-Dependent Repair Following Dicentric Chromosome Breakage in Drosophila melanogaster
Authors: Bhandari Jayaram , Karg Travis , Golic Kent G 
Published: May 2019

Abstract
Double-strand DNA breaks are repaired by one of several mechanisms that rejoin two broken ends. However, cells are challenged when asked to repair a single broken end and respond by: (1) inducing programmed cell death; (2) healing the broken end by constructing a new telomere; (3) adapting to the broken end and resuming the mitotic cycle without repair; and (4) using information from the sister chromatid or homologous chromosome to restore a normal chromosome terminus. During one form of homolog-dependent repair in yeast, termed break-induced replication (BIR), a template chromosome can be copied for hundreds of kilobases. BIR efficiency depends on Pif1 helicase and Pol32, a nonessential subunit of DNA polymerase δ. To date, there is little evidence that BIR can be used for extensive chromosome repair in higher eukaryotes. We report that a dicentric chromosome broken in mitosis in the male germline of Drosophila melanogaster is usually repaired by healing, but can also be repaired in a homolog-dependent fashion, restoring at least 1.3 Mb of terminal sequence information. This mode of repair is significantly reduced in pif1 and pol32 mutants. Formally, the repaired chromosomes are recombinants. However, the absence of reciprocal recombinants and the dependence on Pif1 and Pol32 strongly support the hypothesis that BIR is the mechanism for restoration of the chromosome terminus. In contrast to yeast, pif1 mutants in Drosophila exhibit a reduced rate of chromosome healing, likely owing to fundamental differences in telomeres between these organisms.

Published: May 2019

BACKGROUND:
Our aim was to report the long-term clinical and imaging outcomes of ≤15-year-old children treated for ruptured or symptomatic cerebral aneurysms and to identify prognostic factors for clinical outcome, recurrence, and rebleeding.

METHODS:
We retrospectively identified all pediatric cases of cerebral aneurysm from 2000 to 2015 and then prospectively evaluated long-term occlusion using brain MRI and clinical outcome measures: outcome was considered favorable if King’s Outcome Scale for Childhood Head Injury score was ≥5. We performed univariate analysis and logistic binary regression to identify variables associated with clinical and imaging outcomes.

RESULTS:
Fifty-one children (aged 8.5 ± 1.1 years [mean ± SD], with 37 ruptured and 14 symptomatic aneurysms) were included, and endovascular treatments (84%) or microsurgical procedures (16%) were performed. Despite a 19.6% death rate, at a mean follow-up of 8.3 years, 35 children (68.6%) had a favorable outcome. Annual bleeding and aneurysm recurrence rates were 1.4% ± 1.1% and 2.6% ± 1.8%, respectively. Cerebral ischemia, whether initial or delayed within the first month, was predictive of poor clinical outcome in multivariate analysis (odds ratio: 25; 95% confidence interval: 0.43–143; P &lt; .0001), whereas aneurysm size &gt;5 mm was the only factor associated with recurrence (odds ratio: 14.6; 95% confidence interval: 2.4–86.1; P = .003).

CONCLUSIONS:
Two-thirds of studied ≤15-year-old children suffering from ruptured or symptomatic cerebral aneurysms had long-term favorable outcome. Annual bleeding and aneurysm recurrence rates have shown to be low after endovascular or surgical treatment. Long-term imaging follow-up helps to depict aneurysm recurrence or de novo aneurysm formation and to prevent rebleeding.

Authors: Syed Muneeb Mohammad,Javid Ahmad,Nazir Ahmad Parray Mohd Rafiq Lone*,Nisar Ahmad Ganie,Mohsin Rashid, 
Published: May 2019

Background: Urinary tract infections (UTIs) account for one of the common cause of hospital visits and therefore determination of the antimicrobial susceptibility patterns of uropathogens will help guide physicians to choice the best choice of antibiotics to affected patients. The aim of this study was to isolate the bacteriological agent causing the urinary tract infection and determination of their susceptibility to antibiotics.
Methods: Our study was hospital based prospective study in which patients suspected of UTI were admitted and urine sample were collected using ‘urinary catheter’ method in patients less than 3 years of age, while for older children ‘mid stream clean catch’ method was used. Cultures were bacteriologically analyzed using standard microbiological procedures and antimicrobial susceptibility test was performed for the isolated pathogens.Results: 208 patients with suspected UTI were included in study, out of 208 patients, urine cultures were taken from all patients, 38 cultures (18.2%) were reported as positive. The most common pathogens isolated were Escherichia coli 27 (71%), Klebsiella Species 6 (15%), Enterococcussps 3(7.8%), Proteus sps 1(2.6%), Pseudomonas aeruginosa 1(2.6%). E. coli and Klebsiella showed the highest percentage of resistance to amoxicillin and ampicillin (100%) however, all isolates of E. coli and Klebsiella were susceptible to Nitofurantoin. Among all UTI isolates, least resistance was observed against drugs such as ceftriaxone, cefixime ciproflaxacilin and gentamicin.
Conclusion: The finding of our study showed that E. Coli was the most common uropathogen and there was high resistance to routinely used drugs in clinical practice. So it high time to change the empirical therapy from conventional drugs like ampicillin and amoxicillin to drugs like nitrofurantoin or ciprofloxacilin.
Keywords: Urinary tract infection, urine culture, antibiotic susceptibility.

Subblock Aided OFDM with Index Modulation
Authors: ACAR Yusuf 
Published: May 2019

Recently, orthogonal frequency-division multiplexing (OFDM) with index modulation (IM) has been appeared as a novel method for future wireless communication systems. However, such a mechanism has low spectral efficiency due to some sub-carriers are not activated in order to implicitly convey information. In this paper, a subblock dependent approach, called sub-block aided OFDM-IM (SA-OFDM-IM) technique, is proposed for spectral efficiency enhancement of the OFDM-IM scheme with low complexity. The simulation results illustrate that the proposed SA-OFDM-IM and well known OFDM-IM have the same bit error rate (BER) performance while SA-OFDMIM has40% more spectral efficiency with low complexity
Multispectral Palmprint Recognition Based on Multidirectional Transform
Authors: OZMEN Burcin , OLALEYE Olayinka John 
Published: May 2019

Multispectral palmprint recognition is one of
the most useful biometric techniques due to features obtained from different
spectral resolutions/wavelengths. In this paper, we propose a multidirectional
transform-based feature encoding plan for reliable and robust representation
and matching of multispectral palm images. The method extracts the region of
interest (ROI) for palmprint images captured with non-contact sensors. The
registered ROI of each band is newly downsampled using DWT. This approach
allows us to take more lines into consideration for interpolation. A
undecimated dual-tree complex wavelet transform based multidirectional feature
encoding plan is then newly applied since it provides better shift invariance
and directional selectivity. Finally, a
binary code matching strategy with score level fusion is used to compute
matching for efficient identification. The experimental results obtained on
CASIA and PolyU datasets show that the presented method gives better results in
the blurring binary code matching case than state-of-the-art methods and
provides comparable performance in the non-blurring binary code matching.

Authors: Al-Dweik Ghadeer , Ahmad Muayyad 
Published: May 2019

Background and PurposeNurses face many healthcare challenges, such as high turnover, workload, and unfair assignments, that lead to nurses' dissatisfaction. Linking nursing shift assignment to patients' acuity scores may increase the workload balance, achieving equitable nursing assignment and nurses' satisfaction. This article aimed to (a) describe the effectiveness of the Perroca patient acuity tool (PAT) by measuring nurses' satisfaction with workload and standard of care pre and post the acuity tool application, and (b) measure nurses' satisfaction about the implemented patients' acuity tool.MethodsQuasi-experimental (one group pre- and postdesign) was used. Donabedian's structure-process-outcome (SPO) model was followed as a conceptual model to guide the implementation process of this study. A convenience sample of 64 nurses participated in the study. Two scales were used to measure nurses' satisfaction with workload and with standard of care. Perroca's scale was used to measure nurses' satisfaction about patient acuity level.ResultsSignificant differences were found on nurse's total satisfaction level, satisfaction with workload, and satisfaction with standard of care between the two times, pre- and post–Perroca PAT application. The majority of nurses had positive impressions of the tool.ConclusionThis study concludes that linking PAT to nursing shift assignment has several positive outcomes. It increases nurses' satisfaction and serves as managers' voice for important staffing decisions like recruitment, assignment distribution, employing new staff, and improving quality of care.
