LEVERAGING WRITING AND PHOTOGRAPHY STYLES FOR DRUG TRAFFICKER IDENTIFICATION IN DARKNET MARKETS

Due to its anonymity, there has been a dramatic growth of underground drug markets hosted in the darknet (e.g., Dream Market and Valhalla). To combat drug trafﬁcking (a.k.a. illicit drug trading) in the cyberspace, there is an urgent need for automatic analysis of participants in darknet markets. However, one of the key challenges is that drug trafﬁckers (i.e., vendors) may maintain multiple accounts across different markets or within the same market. To address this issue, in this thesis, we propose and develop an intelligent system named uStyle-uID leveraging both writing and photography styles for drug trafﬁcker identiﬁcation at the ﬁrst attempt. At the core of uStyle-uID is an attributed heterogeneous information network (AHIN) which elegantly integrates both writing and photography styles along with the text and photo contents, as well as other supporting attributes (i.e., trafﬁcker and drug information) and various kinds of relations. Built on the constructed AHIN, a meta-path based approach is exploited to incorporate higher-level semantics to establish relatedness over trafﬁckers. To efﬁciently measure the relatedness over nodes (i.e., trafﬁckers) in the constructed AHIN, we propose a new network embedding model Vendor2Vec to learn the low-dimensional representations for the nodes in AHIN, which leverages complementary attribute information attached in the nodes to guide the meta-path based random walk for path instances sampling. After that, we devise a learning model named uIdentiﬁer to classify if a given pair of trafﬁckers are the same individual. Comprehensive experiments based on the data collections from four darknet markets are conducted to validate the effectiveness of uStyle-uID which integrates our proposed method in drug trafﬁcker identiﬁcation by comparisons with alternative approaches.
Director ownership and performance of small and medium enterprises: insights from Northeast Italy

Purpose of the paper: This article examines the relationship between the proportion of shares that are owned by directors and a firm’s financial performance in small and medium enterprises (SMEs). Methodology: We collected data on ownership and director structures from 214 SMEs in the provinces of Verona and Vicenza (Italy). We used the return on assets (ROA) ratio as a proxy for financial performance over a 4-year period (2014-2017) and implemented an ordinary least squares (OLS) regression model with time-period and industry fixed effects. Results: We found a statistically significant correlation between director ownership and the ROA ratio and identified a nonlinear relationship indicating that the influence of director ownership on performance may be positive or negative and that both the convergence of interests and entrenchment effects are present, depending on the level of ownership and other contextual variables such as it being a family firm, firm age and generational change. Research limitations: Despite our efforts, reverse causality problems cannot be completely excluded. Collecting data in a limited geographical context over a fouryear period restricts the generalization of our results and the use of the Likert scale (1-5) to evaluate managerial ownership may reduce the accuracy of our analysis. Practical implications: Directors and shareholders should carefully consider the benefits deriving from director ownership in overlapping roles, and regulators could better define corporate governance models. Originality of the paper: This study specifically addressed the issue of director ownership in SMEs by considering their relevant contextual variables, such as family firm, firm age, and generational change.
The nurse pivot-navigator associated with more positive cancer care experiences and higher patient satisfaction.

Background and objectives Growing evidence indicates that the nurse navigator-pivot (NN), is key to optimizing care processes and outcomes. However, large scale studies are needed to examine how patients exposed to NNs (as opposed to non-NN) differentially perceived their cancer care experiences. Method Participants (N = 2,858) treated for cancer in the last six months at university-affiliated cancer centres in Montréal, Québec, completed the Ambulatory Oncology Patient Satisfaction Survey (AOPSS). Results Cancer care experiences and satisfaction were significantly higher in the NN group (n = 2,003) for all six care domains (Ds from 3.32 to 8.95) and all four nursing functions (Ds from 5.64 to 10.39) when compared to the non-NN group (n = 855). Discussion The NN role is significantly related to enhanced cancer care experiences and higher patient satisfaction. Future research should explore potential causal effects between NNs and care processes, as well as patient outcomes.
‘The Best Investment of Your Life’: Mortgage Lending and Transnational Care among Ecuadorian Migrant Women in Barcelona

ABSTRACT After Ecuador’s worst economic downturn in 1999, women left the country in the thousands. They migrated for economic reasons but also hoping to distance themselves from gendered duties and obligations that confined them to oppressive feminine roles. Less than a decade later they bought into Spain’s housing bubble in an effort to ‘make up’ for their departure. I argue that Ecuadorian migrant women’s decisions to buy mortgaged homes in Barcelona were in part informed by their conceptualizations of domesticity, care giving, and motherhood. For women portrayed as culpables or ‘culprits’ for leaving Ecuador and failing to upkeep their caregiving responsibilities in their country of origin, the promise of homeownership became a way of accomplishing complex forms of transnational caregiving as well as upward mobility. This article focuses on gendered conceptualizations of care, motherhood, and kinship amongst Ecuadorian migrant women and the relationship these notions have with housing financialization.

Agreement Between Working Length Measurements in Primary Teeth Obtained by Radiographs or Apical Locators

Objective: To perform an in vivo evaluation on the agreement between measurements of working length obtained by conventional radiographic examinations and an apex locator in deciduous teeth with or without root resorption. Material and Methods: Nine canals of teeth from children ranging from 3 to 5 years old were selected. Endodontic access was performed with a spherical diamond tip, the pulp was removed with Kerr-type steel files, and the canal was irrigated with 1% sodium hypochlorite. A file, compatible with the channel gauge, was then used to measure the length of the root canal with the apex locator. Conventional radiographs were also performed and, using a millimeter endodontic ruler, the length of the canal was determined. The differences between the measurements obtained between the two methods were analyzed using the Student's t-test . Results: The mean canal length for conventional radiography was 9.83 mm and 9.67 mm for the apex locator. The results of this study did not show significant differences (p=0.641), independent of the presence or absence of physiological root resorption . Conclusion: The similarity in measurements obtained with X-ray or an apex locator indicates that it is not necessary to use X-rays as a complement to obtain the working length. The use of the apex locator can provide a quicker treatment, reducing the clinical time and stress of the child.
Gambling and gambling problem among elite athletes and their professional coaches: findings from a Swedish total population survey of participants in four sports

ABSTRACT This study assessed the following among elite athletes and their coaches in Sweden: (i) prevalence of gambling and ‘at risk for gambling problems’ (PGSI 3+); and (ii) relations between ‘at risk for gambling problems’ and attitudes towards gambling, experiences of gambling, and individual and demographic factors. A total of 1438 athletes and 401 coaches, in four sports, completed an online survey. Overall, 2% of female athletes and 13% of male athletes were classified as being ‘at risk for gambling problems’. Using an ordinal logistic regression, the results showed associations between ‘at risk for gambling problems’ and eight of the investigated variables: ‘talk about gambling during training’, ‘coaches positive attitude towards gambling’, ‘gambling companies encourage gambling’, ‘I have gambled on own game’, ‘someone I know has gambled on their own game’, ‘gambling is important in the family’, ‘someone in my acquaintance have/had a gambling problem’, ‘alcohol consumption’ among the athletes. Coaches of men’s teams had a higher prevalence (7%) than did coaches of women’s teams (3%). The findings suggest that the sports clubs should have greater knowledge about gambling problems as well as a communication strategy of their acquired knowledge to their athletes and coaches.
Translation in Immunology

For over a century, the role of the immune system in controlling and eradicating tumors has been a subject of intense debate. Since the 1800s, it has been recognized that the immune system also plays an important pathologic protumor role in tumor initiation and progression. Virchow com­ mented on the interaction between inflammation, leukocytes, and cancer in his article from 1863 [1]. More than a hundred years later, we are still extri­ cating the complexities of the interaction between cancers and the host immune system. More recently, Schreiber, Old, and Smyth described the process in which cancer and the immune system interact with each other, termed “cancer immu­ noediting” [2]. Cancer immunoediting describes a contiguous process that the immune system influ­ ences and shapes developing tumors. This process can result in successful rejection of the tumor or generate a tumor through immunologic evasion, the latter of which we now know can occur by multiple mechanisms and more often than not through any one of a number of immune suppres­ sive pathways [3]. Despite the long‐standing interest in host antitumor immunity, it was only recently that immunotherapy emerged as one of the effective treatment options for cancer. In the past decade, several new immunotherapies, such as immune checkpoint blockade agents, tumor antigen– targeted monoclonal antibodies, and a cell‐based dendritic vaccine, were approved by the U.S. Food and Drug Administration (FDA) for the treatment of multiple cancer types. In particular, the immune checkpoint blockade agents, which are treatments that target cytotoxic T‐lymphocyte associated protein 4 (CTLA‐4), programmed cell death pro­ tein 1 (PD‐1), and programmed cell death ligand 1 (PDL‐1), have gained impetus as potent anti­ cancer therapies and have shown promising results across several tumor types, leading to a widespread revolution in cancer treatments and a massive shift in laboratory investigations. Since this form of therapy targets the host’s regulatory components of the immune system rather than specific oncogenic mutations or tumor cells themselves, immune checkpoint blockade has been shown to be effec­ tive across multiple cancer types. Furthermore, given that the immune system has the capacity for Translation in Immunology: The Role of Translational Biomarkers to Guide Clinical Use of Immunotherapy for Cancer
Validation of the MRT-LBM for three-dimensional free-surface flows: an investigation of the weak compressibility in dam-break benchmarks

ABSTRACT Free-surface flow problems occur in numerous disaster simulations, such as tsunami inland penetration in urban areas. Simulation models for these problems must be non-hydrostatic, three-dimensional and highly resolved because of the strong non-linearity and higher-order physical phenomena. However, three-dimensional large-scale tsunami simulations based on conventional computational fluid dynamics (CFD) solving the Navier-Stokes equations are challenging due to the pressure Poisson equation in incompressible Navier-Stokes fluid modeling. The lattice Boltzmann method (LBM) is an alternative simulation tool that is attracting attention as a fully explicit and efficient approach. The LBM does not have to iteratively solve the pressure Poisson equation and is therefore considered to have an advantage over other methods when executing high-performance three-dimensional tsunami simulations. In the current study, we developed a fully explicit free-surface model using the LBM in which the more advanced multiple-relaxation-time (MRT) collision model is used, along with the piecewise linear interface calculation (PLIC) approach. Through classic dam-break problems, we validated the appropriate parameter settings, including the weak compressibility, for tsunami simulations. The benchmark tests showed that our model accurately simulates the three-dimensional dam-break flows and controls the compressibility drop in the second-order value of the Mach number.
ATN status in amnestic and non-amnestic Alzheimer’s disease and frontotemporal lobar degeneration

Under the ATN framework, cerebrospinal fluid analytes provide evidence of the presence or absence of Alzheimer’s disease pathological hallmarks: amyloid plaques (A), phosphorylated tau (T), and accompanying neurodegeneration (N). Still, differences in cerebrospinal fluid levels across amnestic and non-amnestic variants or due to co-occurring pathologies might lead to misdiagnoses. We assess the diagnostic accuracy of cerebrospinal fluid markers for amyloid, tau, and neurodegeneration in an autopsy cohort of 118 Alzheimer’s disease patients (98 amnestic; 20 non-amnestic) and 64 frontotemporal lobar degeneration patients (five amnestic; 59 non-amnestic). We calculated between-group differences in cerebrospinal fluid concentrations of amyloid-β1–42 peptide, tau protein phosphorylated at threonine 181, total tau, and the ratio of phosphorylated tau to amyloid-β1–42. Results show that non-amnestic Alzheimer’s disease patients were less likely to be correctly classified under the ATN framework using independent, published biomarker cutoffs for positivity. Amyloid-β1–42 did not differ between amnestic and non-amnestic Alzheimer’s disease, and receiver operating characteristic curve analyses indicated that amyloid-β1–42 was equally effective in discriminating both groups from frontotemporal lobar degeneration. However, cerebrospinal fluid concentrations of phosphorylated tau, total tau, and the ratio of phosphorylated tau to amyloid-β1–42 were significantly lower in non-amnestic compared to amnestic Alzheimer’s disease patients. Receiver operating characteristic curve analyses for these markers showed reduced area under the curve when discriminating non-amnestic Alzheimer’s disease from frontotemporal lobar degeneration, compared to discrimination of amnestic Alzheimer’s disease from frontotemporal lobar degeneration. In addition, the ATN framework was relatively insensitive to frontotemporal lobar degeneration, and these patients were likely to be classified as having normal biomarkers or biomarkers suggestive of primary Alzheimer’s disease pathology. We conclude that amyloid-β1–42 maintains high sensitivity to A status, although with lower specificity, and this single biomarker provides better sensitivity to non-amnestic Alzheimer’s disease than either the ATN framework or the phosphorylated-tau/amyloid-β1–42 ratio. In contrast, T and N status biomarkers differed between amnestic and non-amnestic Alzheimer’s disease; standard cutoffs for phosphorylated tau and total tau may thus result in misclassifications for non-amnestic Alzheimer’s patients. Consideration of clinical syndrome may help improve the accuracy of ATN designations for identifying true non-amnestic Alzheimer’s disease. Abbreviated Summary Cousins et al. assess the 2018 ATN framework and find that non-amnestic patients with Alzheimer’s disease (AD) have lower cerebrospinal fluid (CSF) phosphorylated tau and total tau than amnestic AD, while CSF amyloid-β accurately stratifies both non-amnestic and amnestic AD from frontotemporal lobar degeneration.
Broadband Microwave Microfluidic Coupled-Line Sensor With 3-D-Printed Channel for Industrial Applications

In this article, a novel microwave microfluidic coupled-line sensor allowing for monitoring of proportional quantities and determination of complex permittivity of liquid dielectric samples through simple analytical formulas is proposed. The application of broadside coupling configuration enabled the sample to be placed in-between coupled strips, thus a high sensitivity can be obtained as the electric field for differential excitation is confined within the sample’s volume. Moreover, the use of 3-D printing technology allowed for the realization of an insert with the microfluidic channel and dedicated liquid inlet/outlet. The sensitivity analysis of such a sensor is provided along with the system calibration technique, which is straightforward because of a fixed and well-defined geometry of the sensor-sample setup. An exemplary, general-purpose sensor along with a cal-kit was realized in a stripline structure and manufactured using a combination of laminate and PolyJet 3-D printing technologies. The broadband measurement results are provided for a water–ethanol solution with variable solvent content up to 12 GHz and for various alcohols featuring frequency-dependent complex permittivity up to 5 GHz. The sensor’s performance is assessed and discussed.
Transitions in Axisymmetric Turbulence

Axisymmetric turbulence is a two-dimensional three-component flow. The investigation of this type of turbulence is motivated by the fact that it represents the asymptotic limit of anisotropic flows and since it has been the subject of theoretical investigations in the past. In the present manuscript such a flow is investigated in wall-bounded cylindrical geometry using spectral and pseudo-spectral numerical simulations.Previous results on the generation of coherent structures, obtained for freely decaying flow, are here assessed in the context of statistically steady flow, where the energy is supplied by either a spectrally localized forcing, or by moving top and bottom plates of the cylinder. It is shown that the observed structures are consistent with theoretical predictions.When an anisotropic forcing protocol is used, a bifurcation is observed from a non-swirling (two-dimensional two-component, 2D2C) flow to a swirling (two-dimensional three-component 2D3C) turbulent flow. This transition is modelled by a system of two ordinary differential equations (ODE), and it is shown that this model retains the essential physics of the transition.The transition of the axisymmetric flow to three-dimensional (3D3C) flow is then studied using non-integer dimension, by smoothly introducing azimuthal variation into the system. It is shown that the 2D2C limit is singular and that small azimuthal variation allows a redistribution of energy over the different energy components. The ODE model is adapted for this system and it is shown that for the considered flow the pressure-strain correlation is responsible for a swirl-level approximately proportional to the non-integer dimension. Large-Eddy Simulations are carried out to assess the robustness of the observations at higher Reynolds number.
Mineral and Bone Status in Tunisian Maintenance Hemodialysis Patients: The National Bone and Mineral Metabolism Observatory

In Tunisia, data assessing the status of mineral and bone disorders (MBD) among dialysis patients is scarce. In order to address this gap in the literature, we sought to conduct this observational study including 4868 patients from 108 hemodialysis facilities nationwide, aiming to: (i) report parameters of MBD during the first quarter 2006, (ii) determine the levels of compliance with the recommendations of the Kidney Disease Outcome Quality Initiative (K/ DOQI), and (iii) compare these levels of compliance with those of Dialysis Outcomes and Practice Patterns Study (DOPPS). Mean serum phosphorus, calcium, calcium- phosphorus product and intact parathyroid hormone (iPTH) concentrations were respectively 1.74 mmol/L, 2.28 mmol/L, 3.95 mmol²/l² and 254 pg/ml. MBD’s measures were met the K/DOQI’s guidelines in 44.1% of cases for serum phosphorus, 42.5% of cases for serum calcium, 68.6% of the cases for calcium phosphorus product, 20.2% of cases for iPTH and 3.3% of cases for these four parameters taken together. These results were comparable to those observed in the DOPPS study. The most phosphate binder prescribed was calcium carbonate (91.2% of cases) with high average daily dose (superior to 1500 mg in 45.8% of cases). Sevelamer and aluminum salt were prescribed respectively in 0.5% and 0.10% of patients. The only active vitamin D available in Tunisia was alfacalcidol; it was prescribed in 49.7% of patients with a mean weekly dose of 4.04 μg. A calcium dialysate bath of 1.75; 1.50 and 1.25 mmol/L were prescribed respectively in 80.2%, 14.7% and 5.1% of cases. This is the first exhaustive study reporting MBD abnormalities in Tunisia and, to our knowledge, in Africa. A second study was stated in January
