Secure Linear Regression on Vertically Partitioned Datasets
Venue: IACR Cryptol. ePrint Arch.
Year: 2016

We propose multi party computation protocols for securely computing a linear regression model from a training dataset whose columns are distributed among several parties. Our solution enables organizations to collaborate in the construction of a predictive model while keeping their training data private. Our approach is based on a hybrid MPC protocol combining garbled circuits with an offline phase enabled by a semi trusted external party. As part of our contribution, we evaluate several algorithms and implementations for solving systems of linear equations using garbled circuts. Experiments conducted with an implementation of our protocols show that our approach leads to highly scalable solutions that can solve data analysis problems with one million records and one hundred features in less than one hour.

Long term use of lithium and factors associated with treatment response among patients with bipolar disorder.
Venue: Psychiatria Danubina
Year: 2016

Lithium has been the gold standard in treating bipolar disorder. In recent years, the use of lithium seems to be diminished although it is well tolerated among the bipolar disorder patients.  This study aimed to evaluate the efficacy and tolerability of lithium as well as to determine factors associated with lithium response among patient with bipolar disorder. A retrospective study was done in a tertiary care hospital in Malaysia which included 47 bipolar disorder patients that were prescribed with lithium maintenance therapy in the time frame of January 2009 until December 2013.  Of all the baseline characteristics tested, only psychotic feature differentiated lithium monotherapy group and combination therapy group significantly (kh(2)=4.732, p=0.03) When compared to period before lithium maintenance, all outcome measures (i.e. annual relapse rate, proportion time spent ill and duration of mood episode) showed significant improvement after lithium maintenance in both treatment groups. Lithium discontinuation only occurred in five cases of adverse effects. Predominant depressive mood episode before lithium maintenance (OR=0.159, p=0.033) and first euthymic interval after lithium maintenance (OR=1.109, p=0.047) significantly predicted lithium response.  Lithium significantly reduced the frequency and time spent in relapse in patients with bipolar disorder. Predominant depressive mood polarity before lithium maintenance and longer first euthymic interval after lithium maintenance had been identified to predict lithium response significantly.
Brain Image Recognition Algorithm and High Performance Computing of Internet of Medical Things Based on Convolutional Neural Network
Venue: IEEE Access
Year: 2019

Due to the wide variety of medical images and the complexity of the human body structure, the characteristics of manual extraction of medical images are difficult, the adaptive ability is poor, and the classification effect needs to be improved. Aiming at the shortcomings of traditional medical image recognition methods, this paper proposes an adaptive convolutional neural network model CNN BN PReLU based on the convolutional neural network method. The model first performs batch normalization (BN) processing on the input of each feature map of each layer of network, and then adaptively adjusts the parameters by using Parametric Rectified Linear Unit (PReLU) to compare the BN algorithm. Based on the performance before and after the activation function, an adaptive convolutional neural network model is constructed. The experimental results show that the model can abstract the image features without artificial intervention, speed up the network convergence speed and shorten the training time, and significantly improve the image recognition rate and reduce the misdiagnosis rate and missed diagnosis rate of the disease.
A STUDY OF THE TRANSLATION OF GOOGLE TRANSLATE
Year: 2020

This study is intended to analyze errors made by Google Translate in translating Eliza Riley's Return to Paradise short story. The method is qualitative descriptive. The data are collected by comparing the translation of Google Translate with that of a professional translator. The errors are analyzed based on Mossop's revision parameters. The findings show that Google Translate failed to recognize idiomatic expressions which caused fatal errors in the target text; errors in word choice that caused word translated out of context; and illogical sentence at the target text caused by cultural difference. As a conclusion, Google Translate may be useful to help translate few words, phrase, and particular sentence in general, and also gives a general comprehension in translating text. However, it may not give an adequate result as a fine translation product. Keyword: google translate, error analysis, Mossop's revision parameters
Cultural Intelligence and Work Family Conflict: A Moderated Mediation Model Based on Conservation of Resources Theory
Venue: International journal of environmental research and public health
Year: 2019

This study aims to explore the influence mechanism of cultural intelligence on work family conflict for Chinese expatriates in cross cultural non profit organizations. Drawing on conservation of resources theory, this longitudinal study (six month time lag) is the first to examine cultural intelligence as an antecedent of work family conflict. The study also examines the mediating role of work engagement and the moderating role of leader member exchange (LMX) in the cultural intelligence and work family conflict relationship. The sample comprises 206 expatriate Chinese language teachers working at 45 Confucius Institutes in the US, Canada, and Russia. Results show that cultural intelligence not only reduces work family conflict but also promotes expatriates' work engagement. The higher the work engagement, the higher the work family conflict experienced by expatriates. LMX moderates not only the positive relationship between work engagement and work family conflict but also the indirect effect of cultural intelligence on work family conflict through work engagement. Thus, the indirect effect of cultural intelligence on work family conflict through work engagement is stronger with low (compared to high) LMX. This study's findings provide implications for managers of cross cultural non profit organizations to better understand and solve expatriates' work family conflict problem.
Genetic algorithm based on support vector machines for computer vision syndrome classification in health personnel
Venue: Neural Computing and Applications
Year: 2018

The inclusion in workplaces of video display terminals has brought multiple benefits for the organization of work. Nevertheless, it also implies a series of risks for the health of the workers, since it can cause ocular and visual disorders, among others. In this research, a group of eye and vision related problems associated with prolonged computer use (known as computer vision syndrome) are studied. The aim is to select the characteristics of the subject that are most relevant for the occurrence of this syndrome, and then, to develop a classification model for its prediction. The estimate of this problem is made by means of support vector machines for classification. This machine learning technique will be trained with the support of a genetic algorithm. This provides the training of the support vector machine with different patterns of parameters, improving its performance. The model performance is verified in terms of the area under the ROC curve, which leads to a model with high accuracy in the classification of the syndrome.
Topological data analysis for true step detection in periodic piecewise constant signals
Venue: Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
Year: 2018

This paper introduces a simple yet powerful approach based on topological data analysis for detecting true steps in a periodic, piecewise constant (PWC) signal. The signal is a two state square wave with randomly varying in between pulse spacing, subject to spurious steps at the rising or falling edges which we call digital ringing. We use persistent homology to derive mathematical guarantees for the resulting change detection which enables accurate identification and counting of the true pulses. The approach is tested using both synthetic and experimental data obtained using an engine lathe instrumented with a laser tachometer. The described algorithm enables accurate and automatic calculations of the spindle speed without any choice of parameters. The results are compared with the frequency and sequency methods of the Fourier and Walsh Hadamard transforms, respectively. Both our approach and the Fourier analysis yield comparable results for pulses with regular spacing and digital ringing while the latter causes large errors using the Walsh Hadamard method. Further, the described approach significantly outperforms the frequency/sequency analyses when the spacing between the peaks is varied. We discuss generalizing the approach to higher dimensional PWC signals, although using this extension remains an interesting question for future research.
Backpropagating Constraints Based Trajectory Tracking Control of a Quadrotor With Constrained Actuator Dynamics and Complex Unknowns
Venue: IEEE Transactions on Systems, Man, and Cybernetics: Systems
Year: 2019

In this paper, a backpropagating constraints based trajectory tracking control (BCTTC) scheme is addressed for trajectory tracking of a quadrotor with complex unknowns and cascade constraints arising from constrained actuator dynamics, including saturations and dead zones. The entire quadrotor system including actuator dynamics is decomposed into five cascade subsystems connected by intermediate saturated nonlinearities. By virtue of the cascade structure, backpropagating constraints (BCs) on intermediate signals are derived from constrained actuator dynamics suffering from nonreversible rotations and nonnegative squares of rotors, and decouple subsystems with saturated connections. Combining with sliding mode errors, BC based virtual controls are individually designed by addressing underactuation and cascade constraints. In order to remove smoothness requirements on intermediate controls, first order filters are employed, and thereby contributing to backstepping like subcontrollers synthesizing in a recursive manner. Moreover, universal adaptive compensators are exclusively devised to dominate intermediate tracking residuals and complex unknowns. Eventually, the closed loop BCTTC system stability can be ensured by the Lyapunov synthesis, and trajectory tracking errors can be made arbitrarily small. Simulation studies demonstrate the effectiveness and superiority of the proposed BCTTC scheme for a quadrotor with complex constrains and unknowns.
Straw mulching with inorganic nitrogen fertilizer reduces soil CO2 and N2O emissions and improves wheat yield.
Venue: The Science of the total environment
Year: 2020

Nitrogen fertilization significantly increases greenhouse gases (GHGs) emission, when applied from inorganic or organic sources. Minimizing GHGs from agroecosystems without compromising crop yield for stabilization of green production systems remains a challenge. Being an integral component of wheat production technology, the nitrogen (N) application deems to be indispensable. Thus, to reduce the application of N fertilizer and keep in view the minimization of GHGs emission, without compromising soil fertility and wheat production, field experiments were performed with treatments included maize straw mulch (S1: 0, S2: 4500, S3: 9000 kg ha 1) and nitrogen fertilizer (N1: 0, N2: 192 and N3: 240 kg ha 1) during 2015 17. Results showed that the cumulative CO2 and N2O emission from 9000 kg ha 1 of maize straw mulch with 192 kg N ha 1 (S3N2) significantly decreased by 0.67% and 33.7% respectively, averaged over two years compared with that of 9000 kg ha 1 of maize straw mulch with 240 kg N ha 1 (S3N3) Likewise, the average soil moisture content significantly increased by 10% and 10.6% for S3N2 and S3N3 treatments at 0 10 cm soil depth, respectively, compared to S1N1. Similarly, the S3N2 and S3N3 treatments had lowered the soil temperature by 0.2 and 0.1 degC, respectively, over S1N1 in wheat grown fields. The grain yield of wheat was increased by 45% and 45% under S3N3 and S3N2 treatments than S1N1, respectively. The S3N2 treatment was more economical than S3N3 for wheat crop. Therefore, maize straw mulch (S3) combined with 20% less N fertilizer (N2) from commercial source were considered as a viable production technology to improve crop yield, and reduce soil CO2 and N2O emissions.

African philosophy and the search for an African philosopher the demise of a conflictual discourse
Year: 2015

There are contending reasons why the rationale, qualification and justification for becoming an African philosopher are still facing the problem of ontology. One reason, as Didier Kaphagawani posits, is premised on the challenges by anthropology and colonialism (1986, 86) Given Oruka, Makinde, Oladipo, Oke, and Hallen's perception of these challenges, they concede that these challenges gave birth to the postcolonial search for a distinct African identity. On the one hand, D. A. Masolo's submission that because "Africa cannot be re subjectivised; hence, an identity which is peculiarly African is impossible" (1997, 283 285) downplays the concession of Kaphagawani, Oruka, et al. Moreover, there tend s to be agreement among certain philosophers who have devoted their time promoting Africana philosophy and culture oriented discourse in Africa like Outlaw, Cabral, Fanon, Makinde, Oladipo, Oke, Hallen, Horton, etc. that "the Western discourse on Africa and the response to such discourse" (MASOLO 1994, 1) led many African philosophers like Nazombe, Okpewho, Tempels, Nkrumah, Nyerere, Senghor, Cesaire, Awolowo, Mandela, etc. to react using socio political and academic means to establish a distinct African philosophical paradigm which craves for the re subjectivisation of Africa. By implication, the response to the Western discourse on Africa, as Outlaw, et al, opine, lend credence to (a) the rationale for the qualification and justification to be an African philosopher; (b) the existence of African philosophy, and (c) the modality of doing philosophy in Africa. Nevertheless, the problem with Outlaw, et al, o n one hand, and D. A. Masolo, on the other, is the failure to recognize that any philosopher need not be of African descent or blood before he can make a meaningful contribution to address the problems facing the development of Africa in all spheres of lif e. This is possible in as much as there is an adequate understanding of the subject under discussion or what it means to do African philosophy. It is this failure or weakness that we shall explore in this essay.  Africa, African Paradigm, African Philosophy, African Philosopher, Identity
