The use of machine learning to identify the correctness of HS Code for the customs import declarations
No full textAs an increasing volume of international trade activities around the world, the amount of cross-boarder import declarations grows rapidly, resulting in an unprecedented scale of potentially fraudulent transactions, in particular false commodity code (e.g., HS Code). The incorrect HS Code will cause duty risk and adversely impact the revenue collection. Physical investigation by the customs administrations is impractical due to the substantial quantity of declarations. This paper provides an automatic approach by harnessing the power of machine learning techniques to relief the burden of customs targeting officers. We introduced a novel model based on the off-the-shelf embedding encoder to identify the correctness of HS Code without any human effort. Determining whether the HS Code is correctly matched with commodity description is a classification task, so the labelled data is typically required. However, the lack of gold standard labelled data sets in customs domain limits the development of supervised-based approach. Our model is developed by the unsupervised mechanism and trained on the unlabelled historical declaration records, which is robust and able to be smoothly adapted by the different customs administrations. Rather than typically classifying whether the HS Code is correct or not, our model predicts the score to indicate the degree of the HS Code being correct. We have evaluated our proposed model on the ground-truth data set provided by Dutch customs officers. Results show promising performance of 71% overall accuracy.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
HS-stability and complex products in involution semigroups
No full textWhen does the complex product of a given number of subsets of a group generate the same subgroup as their union? We answer this question in a more general form by introducing HS-stability and characterising the HS-stable involution subsemigroup generated by a subset of a given involution semigroup. We study HS-stability for the special cases of regular ∗-semigroups and commutative involution semigroups.</p
Modifiable and non-modifiable risk factors in ischemic stroke: a meta-analysis
No full textBackground: Stroke is a heterogeneous, multifactorial disease regulated
by modifiable and non-modifiable risk factors like total cholesterol,
triglycerides, high density lipid-cholesterol (HDL-C), low density
lipid-cholesterol (LDL-C) and glucose and non-modifiable factors like
age. Evaluation of these risk factors for ischemic stroke may
contribute to more effective prevention. Methods: This meta-analysis
investigated the data up to 2018 with respect to age, total
cholesterol, triglycerides, high density lipid-cholesterol (HDL-C), low
density lipid-cholesterol (LDL-C) and glucose levels in the Ischemic
stroke patients and controls. Data from each eligible study was
extracted such as year of publication, first author name,
ethnicity/country, number of ischemic stroke patients and healthy
controls and studies were subjected to heterogeneity analysis. Results:
Meta-analysis of the modifiable and non-modifiable risk factors like
total cholesterol, HDL-C and LDL-C glucose, triglycerides levels and
age were not having significantly associated with ischemic stroke
(p>0.05). However meta-analysis of triglyceride yielded significant
association ischemic stroke with overall 95% CI (-0.62- (-0.09) and P=
0.007 and glucose also showed significant association with ischemic
stroke with 95% CI (-1.08- (-0.14), P=0.01. Studies were subjected to
heterogeneity which revealed significant heterogeneity with (P<0.00)
and I2>96%. Conclusion: Meta-analysis revealed that levels of
triglyceride and glucose are the predisposing factors for ischemic
stroke in the Asian population. DOI:

Global existence for semilinear Schrödinger equations in 2+1 dimensions
No full textAbstractThis paper is concerned with global well-posedness of the 2-dimensional defocusing semilinear Schrödinger equation iut+Δu=|u|2mu in the Sobolev space Hs(R2). In a previous work of Guo and Cui [C. Guo, S. Cui, Global existence for 2D nonlinear Schrödinger equations via high-low frequency decomposition method, J. Math. Anal. Appl. 324 (2006) 882–907] it was proved that global well-posedness holds in Hs(R2) for s>10m−610m−5. That result is obtained by using the high-low frequency decomposition method. In this paper we apply the I-method to improve that result, and prove that global well-posedness holds in Hs(R2) for s>1−5−174m
Age and Gender Tailored Cutoff Value of hs-cTnT Contributes to Rapidly Diagnose Acute Myocardial Infarction in Chest Pain Patients
No full textBackground: Hs-cTnT concentrations are age and gender related, therefore establishment of age and gender optimized cutoff values for hs-cTnT might be essential. We. aimed to define the age and gender specific hs-cTnT 99th percentile in reference population and assess its diagnostic and prognostic performance in patients with suspected AMI. Methods: In this prospective study, 1725 healthy individuals (18 - 97 years old) and 812 patients (15 - 98 years old) with chest pain with suspected AMI presenting to the emergency department were enrolled. The measurement of biomarkers was performed at presentation and at 3 - 4 hours according to clinical requirement. We stratified the reference population by age and gender through applying strict exclusion criteria. Clinical follow-up was obtained after 2 years. Results: The 99th percentile of hs-cTnT according to age and gender in adult Han population of Northern China is reported. The cutoff values of hs-cTnT in for subjects < 70 years, 70 - 79 years, and >= 80 years was 16 ng/L, 38 ng/L, and 57 ng/L, respectively. Among the 812 patients with chest pain, according to the age and gender tailored cutoff value, the specificity and positive predictive value of AMI diagnosis were increased from 53.9% to 72.2% and 48.6% to 60.8%, compared to 14 ng/L commonly recommended. Cumulative 2-year survival rate for patients with hs-cTnT levels above 14 ng/L was 93.3% compared to 99.5% in patients below that level (p < 0.001). The same was observed for the age and gender tailored cutoff value which was 92.5% compared to 98.5%, respectively (p < 0.001). Conclusions: Age and gender tailored cutoff value for hs-cTnT provides better diagnostic information, but yields no additional prognostic performance for risk prediction of death or major adverse cardiovascular events.National Key Technology RD Program [2012BAI37B01]; Application Research of Capital Clinical Characteristic [Z141107006614011]SCI(E)[email protected]

Disaggregating Underlying Drivers of Fruit and Vegetables Trade : an HS-level Modelling Analysis of the AfCFTA
No full textWith the introduction of the African Continental Free Trade Area (AfCFTA), there are expectations to boost interregional trade amongst other measures to increase interregional integration. In particular, the agricultural sector is anticipated to be an important beneficiary of the strengthening and development of interregional linkages from the advent of the AfCFTA. In our paper, we focus on the fruit and vegetables sector, and we implement a new extension of the MAGNET model (Modular Applied GeNeral Equilibrium Tool), a global computable general equilibrium (CGE) model, which has theoretical adaptions in order to model trade flows at the disaggregate HS-level. Fruits and vegetables are high-value crops, which many African countries are switching towards, diversifying their agricultural portfolios away from typical cash crops. In addition, while in many current standard CGE frameworks there is a single aggregate commodity “Veg & Fruit”, in reality, the composition of the underlying products within this aggregate commodity can vary significantly. For this analysis we compare two scenarios: (1) a simulation of AfCFTA with the standard MAGNET model and (2) a simulation of AfCFTA with the HS-level modelling extension. Preliminary simulation results indicate a high difference between the two scenarios in terms of trade flows originating from Southern Africa which depend on several factors, including the tariff shock at the HS- versus GTAP- level, the underlying value of trade from Southern Africa, and the differing theoretical structure of the HS module
