P4Flow: Monitoring Traffic Flows With Programmable Networks

Cloud providers perform flow monitoring to get insights from the network traffic flows, often using coarse-grained packet counters or packet probing. These approaches give partial information from ongoing flows or introduce significant overhead if the probe packets cross multiple hops with diverse delay and bandwidth to reach the traffic collector. Recently, In-band Network Telemetry (INT) offered by programmable networks, e.g., P4, has gained attention by providing fine-grained network telemetry. Current attempts on INT are inflexible in collecting telemetry for customs flows according to the desired interval. This letter proposes P4FLOW, a flow monitoring tool for cloud provider networks implemented on programmable data planes. P4FLOW allows the providers to monitor a set of desired flows according to their needs. It reduces at least 1.6× the overhead of telemetry packets compared with the existing approaches.
How the Personalities and Behaviors of Information Systems Professionals Influence the Effectiveness of Information Systems Departments

ABSTRACT Building on the concept of organizational citizenship behavior (OCB), this study develops a multi-level research model to examine how IS-specific OCBs displayed by IS professionals impact the perceived effectiveness of IS departments, and how the manifestation of IS-specific OCBs is in turn affected by the personal attributes of IS professionals, the leadership style of IS leaders, and the quality of the interactions within IS departments.
Curcumin prevents tenofovir/lamivudine/efavirenzinduced nephrotoxicity in rats

Background and Aims: Nephrotoxicity is an adverse effect, which may occur with the use of tenofovir/lamivudine/efavirenz (TLE) in the treatment of human immune deficiency virus (HIV) infection. Curcumin (CUM), an isolate of Curcuma longa L. is used in folk medicine for the treatment of ailments. This study attempts to establish whether CUM supplementation can protect against a rat model of TLE-induced nephrotoxicity. Materials and Methods: Adult male Wistar rats (n=40) were randomly grouped and supplemented orally with CUM (50, 100 and 200 mg/kg/day) prior to the oral administration of TLE (300/300/600 mg/kg/day) for 30 days. After the treatment, the rats were fasted overnight, weighed and anesthetized. Blood samples were collected, and sera were extracted for biochemical analyses. Kidney samples were excised, weighed and processed for oxidative stress markers and histology. Results: Body weight was decreased (p
Solvent Effects on the Electronic Absorption Spectra of Benzene and Paranitroaniline in UV-Vis Spectroscopy

A UV-Vis spectrophotometer is simple, quick and low cost analytical technique used for the qualitative and quantitative determination of solutes (190 - 800 nm wavelength in the electromagnetic radiation) in both vapour and liquid phase. Depending on the nature of the chromophore, auxochrome, the conjugation, unsaturation properties, steric hindrance, concentration, pH and temperature of the solute and the polarity difference of solvents as well as the interaction of solute-solvent; the intensity, shape and position of maximum electronic absorption spectra of benzene and paranitroaniline influenced in UV/Vis spectroscopy measurement. The main focus of this study were (1) To optimize the working range of plastic and quartz cuvette and the effect of slit width in the spectrum of vapour phase of benzene (2) To determine the interaction effects of benzene with acetonitrile and cyclohexane, and paranitroaniline with water and cyclohexane. Plastic and quartz cuvette optimum working ranges from 300 -800 nm and above 250 nm respectively. The vapour phase with slit width of 0.1 nm and 2 nm and liquid phase in polar (acetonitrile) and non-polar (cyclohexane) of benzene maximum electronic absorption spectrum is observed at 254 nm. In the vapour phase of benzene using 2 nm slit width resolves the smooth spectrum, well resolved and high intensity as compared with 0.1nm slit width. The higher peak and vibration peak in liquid phase of benzene well resolved as compared to vapour phase. In the case of paranitroaniline, the maximum electronic absorption at 380nm shows a bathochromic shift (in water due to dipole-dipole interaction of PNA and water) and at 320nm which shows a hypsochromic shift (in cyclohexane since dipole-induced dipole interaction of PNA and cyclohexane). Therefore, as indicated in benzene and PNA the interaction of solvents matters the shape, position and intensity of maximum absorption spectra in UV/Vis spectroscopy.
Increased compositional heterogeneity of mass‐flowering orchard crops does not promote wild bee abundance in orchards

Due to increasing difficulties to maintain semi‐natural habitat within agricultural landscapes, management of the agricultural matrix may provide a more realistic approach to support farmland biodiversity and associated ecosystem services. We hypothesize that orchard compositional heterogeneity (OCH), that is, different mass‐flowering crops with sequential blooming periods, may support pollinators through continuous abundance of floral resources. We assessed whether increased OCH at the landscape level had a positive effect on wild bee abundances in sweet cherry and apple orchards during bloom. We monitored 15 sweet cherry and 14 apple orchards in Flanders, Belgium, situated along a gradient of OCH. We performed pollinator surveys during bloom to measure wild bee and honey bee abundance and monitored fruit development to assess fruit set and quality. We found no positive effect of OCH on wild pollinator abundance in our study system. Solitary bees showed contrasting responses between crops. Bumble bees showed no response. Wild pollinator abundance had a positive effect on sweet cherry fruit set and apple seed set. Our results imply that increasing crop compositional heterogeneity solely in terms of orchard crops with a limited difference in bloom phenology may prove to be insufficient to support pollinators. We confirm the importance of wild pollinators for pollination services in horticulture.
Predicting the Ki-67 proliferation index in pulmonary adenocarcinoma patients presenting with subsolid nodules: construction of a nomogram based on CT images.

Background The Ki-67 proliferation index (PI) reflects the proliferation of cells. However, the conventional methods for the acquisition of the Ki-67 PI, such as surgery and biopsy, are generally invasive. This study investigated a potential noninvasive method of predicting the Ki-67 PI in patients with lung adenocarcinoma presenting with subsolid nodules. Methods This retrospective study enrolled 153 patients who presented with pulmonary adenocarcinoma appearing as subsolid nodules (SSNs) on computed tomography (CT) images between January 2015 and December 2018. Presence of LUAD with SSNs was confirmed by histopathology. Of these participants, 107 patients were from institution 1 and were divided into a training cohort and an internal validation cohort in a 7:3 ratio. The other 46 patients were from institution 2 and were enrolled as an external validation cohort. All patients underwent conventional CT scans with thin-slice (≤1.25 mm) reconstruction, and 1,316 quantitative radiomic features were extracted from the CT images for each nodule. The minimum redundancy maximum relevance and the least absolute shrinkage and selection operator were used for feature selection, and the radiomics signature was constructed based on these selected features. Clinical features were examined using univariate logistic regression analysis. The nomogram was developed based on the radiomics signature and the independent clinical risk factors. The Delong test and t test were employed for statistical analysis. The performance of different models was assessed by the receiver operating characteristic (ROC) curve. Results The diameter of the nodules [odds ratio (OR) =1.17; P=0.003] was identified as an independent predictive parameter. Both the radiomics signature and the nomogram suggested a good predictive probability for Ki-67 expression. For the radiomics signature, the area under the ROC curve (AUC) for the training cohort, the internal validation cohort, and the external validation cohort was 0.86 [95% confidence interval (CI): 0.77 to 0.95], 0.81 (95% CI: 0.64 to 0.98), and 0.77 (95% CI: 0.62 to 0.91), respectively. For the nomogram, the AUC for the training cohort, the internal validation cohort, and the external validation cohort was 0.86 (95% CI: 0.77 to 0.95), 0.80 (95% CI: 0.64 to 0.97), and 0.79 (95% CI: 0.65 to 0.94), respectively. There were no statistical differences in the AUCs between the radiomics signature and the radiomic nomogram in the training cohort or the validation cohorts (all P>0.05). Conclusions The nomogram provides a novel strategy for determining the Ki-67 PI in predicting the proliferation of subsolid nodules, which may be beneficial for the management of patients with SSNs.

Comparison of domain specific connectivity metrics for estimation brain network indices in boys with ADHD-C

The study includes Graph Theoretic advanced EEG analysis in order to investigate the impact of pharmacological treatment with osmotic release oral system-methylphenidate for a month in 18 boys (aged between 7-12 years) with Attention-Deficit-Hyperactivity Disorder, combined type. In analysis, neurofunctional dependency levels across the cortex are estimated by using six different connectivity estimation approaches based on three separate domains such as time (Pearson Correlation, Spearman Correlation), frequency (Directed Transfer Function, Partial Directed Coherence) and phase (Phase Locking Value, Phase Lag Index). All methods are examined for eyes-opened resting-state EEG segments of 2 sec over a single trial of 1 min in both pre- and post-treatment recordings. Then, five quantitative brain network indices of transitivity, clustering coefficients, assortativity, global efficiency and modularity are computed from connectivity estimations. Performance of connectivity estimators are compared to each other with respect to two-class classifications (pre-treatment features vs post-treatment features) by using Support Vector Machines driven by brain network indices. The highest classification accuracy of 80.74% is obtained with Pearson Correlation. Statistical one-way Anova test, pair-wise multiple comparison test and step-wise logistic regression modelling are all used to observe the most sensitive network index estimated from Pearson Correlations. In addition to quantitative results, statistical box-plots of the estimated network indices are shown graphically. When modularity index is excluded from the features, classification accuracy is increased to 83.79%. Overall results reveal that brain segregation and resilience are increased by the treatment. In particular, the most meaningful brain network measures can be estimated from time domain statistical correlations between resting-state eyes open EEG segments in order to understand the alterations in neuronal transmission mechanism across the cortex in response to a specific treatment in pediatric psychiatry.
Limitations of immigrant entrepreneurship research

Immigrant entrepreneurship research has, so far, addressed various topics and contributed to the advancement of the overall understanding associated with the entrepreneurial behaviour of immigrants. However, research on this field incorporates several limitations. Based on narrative review of the relevant literature, five limitations associated with immigrant entrepreneurship research were identified: 1) geographical bias (research concentration in a few OECD countries particularly the USA); 2) ethnic limitations (research focus on certain ethnic groups); 3) conceptual misspecification (definitional boundaries have not been properly set); 4) thematic bias (research focus on business antecedents than on business outcomes); 5) methodological bias (dominance of quantitative research and small sampling). Necessary implications have as well been illustrated in this paper. Future researchers need to address these limitations or, at least, avoid replicating them to strengthen the research outputs.
Investigation of Corporate Social Responsibility in Sports within The Scope of Corporate Sustainability

The idea of corporate social responsibility dates back nearly a century, but it is not long ago that the concept was put into action by organizations and studied by researchers. While the first official examination of the concept dates back to the 1950s, it was in the 1980s that people began to question and expect social responsibility practices from organizations. It was the early 2000 that the concept was examined in the field of sports and attracted the attention of researchers. When the corporate social responsibility studies carried out within the scope of sustainability in the field of sports are examined, it is seen that the importance of such practices in terms of organizations is mostly investigated topic. In the research papers, it was also examined how the corporate social responsibility activities carried out by professional sports organizations were received by sports fans and stakeholders. In our study, the place of corporate social responsibility in the field of sports was investigated within the scope of corporate sustainability. When examining studies in the field, it is seen that sport are a valuable tool for sustainable development and corporate sustainability, and that sports organizations should include corporate social responsibility activities in their strategic plans. Considering it’s power to reach the society, it is thought that corporate social responsibility in the field of sports is an important field that needs to be worked on in order to ensure sustainable development and corporate sustainability.

Perception of Social Speaker Characteristics in Synthetic Speech

With the improved computational abilities, the usage of chat-bots and conversational agents has become more prevalent. Therefore, it is essential that these agents exhibit certain social speaker characteristics in the generated speech. In this paper, we study the perception of such speaker characteristics in two commercial Text-to-Speech (TTS) systems, Amazon Polly and Google TTS. We carried out a 15-item semantic differential scaling test. The factor analysis provided us with three underlying dimensions that can be perceived from synthetic speech, warmth, competence, and extraversion. Our results show that we can perceive both interpersonal relationships and also personality traits from synthetic voices. Additionally, we observed that the female participants perceived male voices to be more responsible, energetic, relaxed, and enthusiastic. In comparison, male participants found female voices to be more reliable, accessible, and conﬁdent. A discussion on the comparison of our results with that of the studies on natural speech is also provided.
A Parallel Algorithm for Scheduling a Two-Machine Robotic Cell in Bicycle Frame Welding Process

Welding frames with differing geometries is one of the most crucial stages in the production of high-end bicycles. This paper proposes a parallel algorithm and a mixed integer linear programming formulation for scheduling a two-machine robotic welding station. The time complexity of the introduced parallel method is O(log2n) on an n3-processor Exclusive Read Exclusive Write Parallel Random-Access Machine (EREW PRAM), where n is the problem size. The algorithm is designed to take advantage of modern graphics cards to significantly accelerate the computations. To present the benefits of the parallelization, the algorithm is compared to the state of art sequential method and a solver-based approach. Experimental results show an impressive speedup for larger problem instances—up to 314 on a single Graphics Processing Unit (GPU), compared to a single-threaded CPU execution of the sequential algorithm.
The Effect of Dynamic Neuromuscular Stabilization (DNS) on the Respiratory Function of Subjects with Forward Head Posture (FHP)

PURPOSE: The purpose of this study was to apply dynamic neuromuscular stabilization (DNS) to subjects with forward head posture (FHP) and to compare its effects on respiratory function as against the conventional neck stabilization exercise and neck stretching and extensor strengthening exercises. METHODS: The whole-body posture measurement system was used to measure the degree of FHP, and a spirometer and a respiratory gas analyzer were used to measure the respiratory function. After the intervention was completed, the changes over time were analyzed in the DNS group, the neck stabilization exercise group, and the neck stretching and extensor strengthening exercise group. The inter-group difference in the changes was also analyzed. A repeated ANOVA was performed to compare the respiratory function according to the period between the three groups, and the least significant difference (LSD) method was used for the post hoc test. RESULTS: After the 6-week exercise period, respiratory
Insular networks: An exploration of material distribution, insularity and island identity on the edge of Europe in the Shetland Neolithic

Abstract Shortly after arriving in the Shetland archipelago early in the 4th millennium BC, communities began to quarry and make stone tools from riebeckite felsite, quarried from the Northmavine region of North Mainland. The effort expended traveling to the quarry sites, extracting, making and crafting tools was considerable indicating the importance of felsite to Neolithic communities. Results from the North Roe Felsite Project are presented in this paper. The quarrying and distribution of felsite in Shetland can tell us much about insularity, choice, and island identities on a wider scale. The geospatial distribution of 416 felsite tools from across the archipelago was explored. Felsite is used to make tools for utilitarian and ceremonial purposes and, with two exceptions compromising 0.33% of the total dataset, no tools can be securely provenanced outside of Shetland. At a time of increasing communications elsewhere in the Neolithic world, communities in Shetland appear to become focused on the archipelago. This insularity is also evident in contemporary material culture including pottery and funerary structures which do not follow mainland or Orcadian styles, strongly suggesting an island-focused society during this period. Recent radiocarbon dates suggest that these dynamics were established in the Early Neolithic, before 3500 BC. Felsite, therefore, allows us to explore the otherwise elusive early prehistory of the islands. The distribution network of tools from the quarry complex around the archipelago strongly indicates a preference for maritime travel and transportation, even where terrestrial routes are available. The patterns also suggest settlement and activity across Shetland with important foci at previously understudied locations across North and West Mainland. The study has considerable implications for understanding movement, choice, and identity in past island societies and their relationship to material culture.
Self-Control Dynamics in Daily Life: The Importance of Variability Between Self-Regulatory Strategies and Strategy Differentiation

Research on self-control has increasingly acknowledged the importance of self-regulatory strategies, with strategies in earlier stages of the developing tempting impulse thought to be more effective than strategies in later stages. However, recent research on emotion regulation has moved away from assuming that some strategies are per se and across situations more adaptive than others. Instead, strategy use that is variable to fit situational demands is considered more adaptive. In the present research, we transfer this dynamic process perspective to self-regulatory strategies in the context of persistence conflicts. We investigated eight indicators of strategy use (i.e., strategy intensity, instability, inertia, predictability, differentiation, diversity, and within- and between-strategy variability) in an experience sampling study (N = 264 participants with 1,923 observations). We found that variability between strategies was significantly associated with self-regulatory success above and beyond mean levels of self-regulatory strategy use. Moreover, the association between trait self-control on one hand and everyday self-regulatory success and affective well-being on the other hand was partially mediated by between-strategy variability. Our results do not only show the benefits of variable strategy use for individual’s self-regulatory success but also the benefits of more strongly connecting the fields of emotion regulation and self-control research.
Genetic diversity and restricted genetic connectivity in an endangered marine fish (Brachionichthys hirsutus) provides a model for conservation management in related and data-deficient species

Determining the genetic diversity and differentiation among populations is a critical element of conservation biology, but for many aquatic, data-deficient species with small population sizes, this is not possible. Closely related species may therefore provide a model. For the first time, using over 4000 single-nucleotide polymorphism loci, we characterise the population genetic diversity and structure of one of the world’s rarest marine fish, the spotted handfish (Brachionichthys hirsutus), a species which is also a member of the most threatened marine bony fish family (Brachionichthyidae). Fin clips were taken from 170 live spotted handfish across seven disjunct sites within the only known estuary (in Tasmania, Australia) where multiple populations of the species are found. Spatially discrete populations clustered into three genetic groupings and a significant variance in allele frequencies among populations (overall FST=0.043), even at the small scale of the estuary, was observed. Furthermore, low contemporary migration rate estimates suggest low genetic homogeneity between locations. Because of the low genetic connectivity, population clusters of spotted handfish within the estuary should be considered as separate conservation management units. This insight should be considered for management and conservation strategies of other data-deficient and threatened species in the family.
