Anti-discrimination learning: a causal modeling-based framework

Anti-discrimination learning is an increasingly important task in data mining. Discrimination discovery is the problem of unveiling discriminatory practices by analyzing a dataset of historical decision records, and discrimination prevention aims to remove discrimination by modifying the biased data and/or the predictive algorithms. Discrimination is causal, which means that to...

Elimination of Bimodal Size in InAs/GaAs Quantum Dots for Preparation of 1.3-μm Quantum Dot Lasers

The device characteristics of semiconductor quantum dot lasers have been improved with progress in active layer structures. Self-assembly formed InAs quantum dots grown on GaAs had been intensively promoted in order to achieve quantum dot lasers with superior device performances. In the process of growing high-density InAs/GaAs quantum dots, bimodal size occurs due to large...

Effects of melatonin administration on embryo implantation and offspring growth in mice under different schedules of photoperiodic exposure

Embryo implantation is crucial for animal reproduction. Unsuccessful embryo implantation leads to pregnancy failure, especially in human-assisted conception. Environmental factors have a profound impact on embryo implantation. Because people are being exposed to more light at night, the influence of long-term light exposure on embryo implantation should be explored. The effects...

Characteristics of gas evolution profiles during coal pyrolysis and its relation with the variation of functional groups

Strict relation between the substituents or functional groups attached to the coal macromolecules and the generation of the volatile products, e.g., CH4, H2O, CO, CO2, etc., during the coal pyrolysis is an important but confusing subject. In this paper, quadrupole mass spectrometry, gas chromatography, and 13C nuclear magnetic resonance are applied to real-time monitoring the...

Construction of lower and upper solutions for first-order periodic problem

In this paper, we construct nonconstant lower and upper solutions for the periodic boundary value problem x ′ + f ( t , x ) = e ( t ) , x ( 0 ) = x ( T ) and find their estimates. We prove the existence of positive solutions for the singular problem x ′ + g ( x ) = e ( t ) , x ( 0 ) = x ( T ) by using these results. MSC: 34B10, 34B18.

The relationship between diabetes and colorectal cancer prognosis: A meta-analysis based on the cohort studies

two groups (Bo Zhu, Bo Wu as a group, and Lu Zhang, Lixuan Wei as another group) in multiple databases (Pubmed, Web of Science, Embase and Google Scholar) up to March 19, 2017. In order to collect as

The Negative Relationship between Bilirubin Level and Diabetic Retinopathy: A Meta-Analysis

Objectives Findings on the relationship between total bilirubin level (TBL) and diabetic retinopathy (DR) are inconsistent. Thus, we carried out a meta-analysis to investigate the relationship between TBL and the risk of DR. Methods Relevant studies were selected from six databases up to 31 May 2016 using a search strategy. The relevant data were extracted from the included...

Reconstructing directed gene regulatory network by only gene expression data

Background Accurately identifying gene regulatory network is an important task in understanding in vivo biological activities. The inference of such networks is often accomplished through the use of gene expression data. Many methods have been developed to evaluate gene expression dependencies between transcription factor and its target genes, and some methods also eliminate...

The Efficacy and Safety of Current Treatments in Diabetic Macular Edema: A Systematic Review and Network Meta-Analysis

Purpose To compare the efficacy and safety of current treatments in diabetic macular edema (DME). Methods PubMed, Embase and CENTRAL were systematically reviewed for randomized controlled trials of current treatments in DME through August 2015. Data on the mean change of best-corrected visual acuity (BCVA) and central macular thickness (CMT) were extracted, and adverse events...

Traditional Chinese medicine combination therapy for patients with steroid-dependent ulcerative colitis: study protocol for a randomized controlled trial

Background Approximately 20% of patients with ulcerative colitis become steroid dependent. Azathioprine is recommended in steroid-dependent ulcerative colitis, but its side effects limit its use. Chinese herbal medicine has been widely used to treat ulcerative colitis in China. However, its effectiveness in steroid-dependent patients has not been evaluated. This study aims to...

Morphine versus methylprednisolone or aminophylline for relieving dyspnea in patients with advanced cancer in China: a retrospective study

Context Dyspnea is one of the most common and distressing symptoms that occurs in terminal cancer patients. However, there are no existing treatment guidelines for this condition in China. Objective This single-center, retrospective, observational study aimed to compare the efficacy of using morphine, methylprednisolone, or aminophylline to relieve the symptom of breathlessness...
