Differential Study of Deep Network Based Image Retrieval Methods
Authors: Mahajan Arpana , Chaudhary Sanjay
Published: October 2019

Learning successful component portrayals and likeness measures are essential to the recovery execution of a substance based image recovery (CBIR) framework. In spite of broad research endeavors for quite a long time, it stays one of the most testing open issues that extensively thwarts the accomplishments of genuine world CBIR frameworks. The key test has been ascribed to the outstanding “semantic hole” issue that exists between low-level image pixels caught by machines and elevated level semantic ideas saw by a human. Among different methods, AI has been effectively examined as a conceivable course to connect the semantic hole in the long haul. Propelled by late triumphs of profound learning strategies for PC vision and different applications, in this paper, we endeavor to address an open issue: if profound learning is a desire for spanning the semantic hole in CBIR and how much upgrades in CBIR undertakings can be accomplished by investigating the cutting edge profound learning procedures for learning highlight portrayals and comparability measures. In particular, we research a structure of profound learning with application to CBIR assignments with a broad arrangement of exact investigations by inspecting cutting edge profound learning strategies for CBIR undertakings under shifted settings. From our experimental investigations, we locate some promising outcomes and abridge some significant bits of knowledge for future research.
Co-cooking nonwoods with hardwoods
Authors: RUNGE TROY , ZHANG CHUNHUI
Published: October 2019

Agricultural residues and energy crops are promising resources that can be utilized in the pulp and paper industry. This study examines the potential of co-cooking nonwood materials with hardwoods as means to incorporate nonwood material into a paper furnish. Specifically, miscanthus, switchgrass, and corn stover were substituted for poplar hardwood chips in the amounts of 10 wt %, 20 wt %, and 30 wt %, and the blends were subjected to kraft pulping experiments. The pulps were then bleached with an OD(EP)D sequence and then refined and formed into handsheets to characterize their physical properties. Surprisingly, all three co-cooked pulps showed improved strength properties (up to 35%). Sugar measurement of the pulps by high-performance liquid chromatography suggested that the strength increase correlated with enriched xylan content.

Published: October 2019

The main goal of this study was to evaluate the potential of depithed bagasse for the production of printing and writing paper. Industrial whole bagasse was separated into two fractions: pith and depithed bagasse. The depithed bagasse was cooked by the soda process to two different degrees of delignification. The resulting pulps were fully bleached by the O-D*-(EP)-D sequence and characterized for their beatability, drainability, and physical-mechanical properties. Bleached soda pulps cooked to kappa 17.5 and 10.8 showed similar refinability and resistance to drainage, but the strength properties (tensile, burst, and tear) were slightly higher for the kappa 17.5 pulp at beating energy consumptions in the range of 2-7 W•h. We concluded that both pulps from depithed sugar cane bagasse would be suitable for the production of printing and writing paper grade pulps, but the higher kappa pulp is more economically attractive given its higher pulping yield, without significantly increasing the bleaching chemical demand.

Authors: Méndez Sánchez Cecilia , Palacios Salas Pedro , Sahagún Padilla Miguel Angel , Hermosillo de la Torre Alicia Edith
Published: October 2019

Las reacciones que tienen los niños frente a una tarea pueden ser explicadas desde la forma en que la perciben. En este estudio se busca establecer las diferencias en el comportamiento no verbal que los niños presentan ante dos tareas cuya naturaleza es distinta. Participaron 72 niños de educación primaria procedentes de tres centros educativos  de la ciudad de Aguascalientes. Los participantes debían resolver una tarea lúdica (tangram) y una tarea académica (problema matemático) bajo dos situaciones: cooperación y competición. La tarea académica llevó a los niños a presentar más comportamientos para reducir la tensión y para facilitar la tarea en comparación con la tarea lúdica. La combinación de la naturaleza de la tarea y la demanda tienen un mayor efecto en la realización de estos comportamientos.

Published: October 2019

Los gestos de las madres influyen en el desarrollo del vocabulario de sus hijos (Iverson et al., 1999). El objetivo de este estudio es analizar la relación entre la producción gestual de las madres y la producción léxica de sus hijos en una tarea de lectura conjunta. Participaron 30 díadas madre-infante, monolingües hablantes nativos del español: 15 con infantes de 30 meses y 15 con infantes de 48 meses, niños y niñas con desarrollo típico. Se realizó una tarea de lectura conjunta; se registró la producción de gestos deícticos de las madres y la producción léxica de los infantes (palabras type y token). En las díadas de infantes de 48 meses, se encontró una correlación positiva entre la producción gestual de las madres y la amplitud en la producción de palabras de sus hijos. La gestualidad de las madres es una variable asociada al tamaño del vocabulario productivo de sus hijos.
Familias, escuelas y estudiantes de educación superior
Authors: Romo Martínez Matías
Published: October 2019

Se presentan resultados de una investigación con estudiantes de educación superior, ideas respecto de su propia familia y la relación que ésta ha tenido con las escuelas a las que aquéllos han asistido. Existen múltiples trabajos acerca de la relación escuelas-familias en la educación básica, pero no en educación superior. Si se considera estos dos ámbitos como los principales responsables de la socialización primaria, la aparente distancia que van tomando los estudiantes respecto de sus familias conforme se avanza en los niveles educativos, sólo se esperaría en términos de un desarrollo de la autonomía durante la juventud. Los resultados obtenidos reflejan un “arropamiento” familiar importante y constante durante toda su trayectoria; además, se muestran respuestas de estudiantes universitarios y de tres Escuelas Normales, todos en Aguascalientes. En la mayoría de los casos pareciera que prevalecen familias tradicionales y estables que pueden ofrecer buenas condiciones para los estudios
La evolución socio-histórica semiótica del verbo como representante de la experiencia
Authors: Forzán de Lachica Ana Luisa
Published: October 2019

El objetivo de estala presente revisión fue describir la evolución socio-histórica de la construcción del significado y signo del verbo en la lengua española como representante de la experiencia (lo dinámico) en oposición a la sustancia (lo estático). Lo anterior, con el fin de encontrar pistas para la reflexión del desarrollo cognitivo con énfasis en la formación del símbolo de la experiencia. Con base en los grandes debates de filósofos, lingüistas y gramáticos describimos el proceso socio-histórico desde la época clásica con los gramáticos grecolatinos hasta nuestros días. También realizamos una reconstrucción de hechos a través del empleo de evidencias documentales confiables. La exploración socio-histórica nos permitió dimensionar lo que los principales lingüistas y académicos de la lengua española han demostrado sobre la dificultad que presenta esta categoría por su riqueza formal, sintáctica y semántica. Si dicha riqueza y complejidad las llevamos al campo del desarrollo cognitivo, específicamente en la formación del símbolo en el niño, para advertir algunos indicios puede resultar interesante. Eventualmente, esta exploración puede colaborar para dialogar con los planteamientos que abordan dicha formación a partir de la sustancia e indagar sobre la formación del símbolo de la experiencia.

Authors: Ríos Ponce Alma Esperanza , Luna Umanzor Diana Iris , Arias-Trejo Natalia
Published: October 2019

El envejecimiento forma parte del desarrollo de la vida humana y lleva consigo una serie de cambios físicos, cognitivos, biológicos y conductuales que se pueden considerar normales dentro de los parámetros de esta evolución. Cuando estos cambios producen dificultades cognitivas y afectan la independencia de la persona, existe la posibilidad de padecer una demencia. Alteraciones en áreas como la memoria y el lenguaje han sido estudiadas a través de distintos métodos como la tarea de asociación de palabras, que permiten conocer la organización de la memoria semántica y han sido usadas para estudiar cambios en el lenguaje. La presente investigación tiene como objetivo la identificación de cambios en las relaciones léxicas en dos patologías, - enfermedad de Alzheimer y demencia mixta, - a través de este tipo de tarea. Los resultados indican mayor deterioro de las relaciones léxicas en los participantes con enfermedad de Alzheimer que en aquellos con demencia mixta respecto a los grupos controles.

Authors: ŞARBAK Ayşegül
Published: October 2019

Geç Roma-Erken Bizans Dönemine tarihlendirilen Akgüney toplumu Sinop ilinde yer almaktadır. Çalışmanın amacı Akgüney toplumu dişlerini paleopatolojik açıdan inceleyerek toplumun sağlık yapısını belirlemektir. Dişler antik dönem toplumlarının beslenme ve sağlık yapılarının ortaya konulmasında en önemli materyallerdendir. Bu nedenle Akgüney toplumuna ait 170 bireye ait 631 diş paleopatolojik açıdan incelenmiştir. Yapılan analizler sonucunda toplumda %9,12 oranında diş çürüğü, %28,98 oranında diş taşı,%40,29 oranında hipoplasya görülmüştür. Ayrıca toplumda %7,82 oranında antemortem diş kaybı, %41,43 oranında alveol kaybı, %1,16 oranında apse tespit edilmiştir. Toplumdaki aşınma oranına bakıldığında ise en çok orta (3) dereceli diş aşınması gözlemlenmiştir. Akgüney toplumunun diş çürüğü diş taşı, hipoplasya oranı çağdaş toplumlarına yakın bir değerdedir. Diş sağlığını ve ağız hijyenini yansıtan patolojik olgulardan biri olan apse ise çağdaş toplumlardan biraz daha düşüktür. Aşınma derecesi ise yine çağdaş toplumlara yakın değerde olduğu görülmektedir. Sonuç olarak Akgüney toplumunun beslenmesinde karbonhidratlı besinlerin olduğunu gösterirken, diş taşı, antemortem diş kaybı ve alveol kaybı oranları ise toplumun ağız hijyeninin ve diş sağlığınınçok da iyi olmadığını göstermektedir.

A Focus on Soft Actuation
Authors: Miriyev Aslan
Published: October 2019

The present editorial paper analyzes the hundred recent research works on soft actuation to understand the current main research focus in the light of the grand challenges in the field. Two characteristic paper types were obtained: one focuses on soft actuator design, manufacturing and demonstration, while another includes in addition the development of functional materials. Although vast majority of the works showcased soft actuation, evaluation of its robustness by multi-cyclic actuation was reported in less than 50% of the works, while only 10% described successful actuation for more than 1000 cycles. It is suggested that broadening the research focus to include investigation of mechanisms underlying the degradation of soft functional material performance in real cyclic actuation conditions, along with application of artificial intelligence methods for prediction of muscle behavior, may allow overcoming the reliability issues and developing robust soft-material actuators. The outcomes of the present work might be applicable to the entire soft robotics domain.
Development and Testing of Woven FRP Flexure Hinges for Pressure-Actuated Cellular Structures with Regard to Morphing Wing Applications
Authors: Meyer Patrick , Boblenz Johannes , Sennewald Cornelia , Vorhof Michael , Hühne Christian , Cherif Chokri , Sinapius Michael
Published: October 2019

Shape-variable structures can change their geometry in a targeted way and thus adapt their outer shape to different operating conditions. The potential applications in aviation are manifold and far-reaching. The substitution of conventional flaps in high-lift systems or even the deformation of entire wing profiles is conceivable. All morphing approaches have to deal with the same challenge: A conflict between minimizing actuating forces on the one hand, and maximizing structural deflections and resistance to external forces on the other. A promising concept of shape variability to face this challenging conflict is found in biology. Pressure-actuated cellular structures (PACS) are based on the movement of nastic plants. Firstly, a brief review of the holistic design approach of PACS is presented. The aim of the following study is to investigate manufacturing possibilities for woven flexure hinges in closed cellular structures. Weaving trials are first performed on the material level and finally on a five-cell PACS cantilever. The overall feasibility of woven fiber reinforced plastics (FRP)-PACS is proven. However, the results show that the materials selection in the weaving process substantially influences the mechanical behavior of flexure hinges. Thus, the optimization of manufacturing parameters is a key factor for the realization of woven FRP-PACS.
Facile Preparation of Multilayered Graphene with CO2 as a Carbon Source
Authors: Dong Hongyu , Guo Shaoqing , Zhao Liangfu
Published: October 2019

A facile and controllable route for fabricating multilayered graphene was provided using CO2 as a carbon source. A typical multilayered graphene structure was obtained with the reaction between CO2 and magnesium metal. The reaction was carried out under different CO2 gas flows, reaction temperatures, and reaction times with two types of metal Mg (Mg powder and Mg ribbon). Moreover, the effect of different concentrations of HCl solution for sample post-processing was discussed in this study. The results of transmission electron microscopy (TEM), energy dispersive spectrometer (EDS), Raman spectroscopy and X-ray powder diffraction (XRD) confirm the formation of multilayered graphene. This work proposed a new method for a controllable way to produce multilayered graphene with gaseous CO2 as a carbon source.
Business Process Automation: A Workflow Incorporating Optical Character Recognition and Approximate String and Pattern Matching for Solving Practical Industry Problems
Authors: de Jager Coenrad , Nel Marinda
Published: October 2019

Companies are relying more on artificial intelligence and machine learning in order to enhance and automate existing business processes. While the power of OCR (Optical Character Recognition) technologies can be harnessed for the digitization of image data, the digitalized text still needs to be validated and enhanced to ensure that data quality standards are met for the data to be usable. This research paper focuses on finding and creating an automated workflow that can follow image digitization and produce a dictionary consisting of the desired information. The workflow introduced consists of a three-step process that is implemented after the OCR output has been generated. With the introduction of each step, the accuracy of key-value matches of field names and values is increased. The first step takes the raw OCR output and identifies field names using exact string matching and field-values using regular expressions from an externally maintained file. The second step introduces index pairing that matches field-values to field names based on the location of the field name and value on the document. Finally, approximate string matching is introduced to the workflow, which increases accuracy. By implementing these steps, the F-measure for key-value pair matches is measured at 60.18% in the first step, 80.61% once index pairing is introduced, and finally 90.06% after approximate string matching is introduced. The research proved that accurate usable data can be obtained automatically from images with the implementation of a workflow after OCR.
Destined to Die: Apoptosis and Pediatric Cancers
Authors: Choo Zhang’e , Loh Amos Hong Pheng , Chen Zhi Xiong
Published: October 2019

Apoptosis (programmed cell death) is a systematic and coordinated cellular process that occurs in physiological and pathophysiological conditions. Sidestepping or resisting apoptosis is a distinct characteristic of human cancers including childhood malignancies. This review dissects the apoptosis pathways implicated in pediatric tumors. Understanding these pathways not only unraveled key molecules that may serve as potential targets for drug discovery, but also molecular nodes that integrate with other signaling networks involved in processes such as development. This review presents current knowledge of the complex regulatory system that governs apoptosis with respect to other processes in pediatric cancers, so that fresh insights may be derived regarding treatment resistance or for more effective treatment options.

These studies compared the efficacies of our clinical agent galeterone (Gal) and the FDA-approved prostate cancer drug, enzalutamide (ENZ) with two lead next generation galeterone analogs (NGGAs), VNPP414 and VNPP433-3β, using prostate cancer (PC) in vitro and in vivo models. Antitumor activities of orally administered agents were also assessed in CWR22Rv1 tumor-bearing mice. We demonstrated that Gal and NGGAs degraded AR/AR-V7 and Mnk1/2; blocked cell cycle progression and proliferation of human PC cells; induced apoptosis; inhibited cell migration, invasion, and putative stem cell markers; and reversed the expression of epithelial-to-mesenchymal transition (EMT). In addition, Gal/NGGAs (alone or in combination) also inhibited the growth of ENZ-, docetaxel-, and mitoxantrone-resistant human PC cell lines. The NGGAs exhibited improved pharmacokinetic profiles over Gal in mice. Importantly, in vivo testing showed that VNPP433-3β (at 7.53-fold lower equimolar dose than Gal) markedly suppressed (84% vs. Gal, 47%; p < 0.01) the growth of castration-resistant PC (CRPC) CWR22Rv1 xenograft tumors, with no apparent host toxicity. ENZ was ineffective in this CRPC xenograft model. In summary, our findings show that targeting AR/AR-V7 and Mnk1/2 for degradation represents an effective therapeutic strategy for PC/CRPC treatment and supports further development of VNPP433-3β towards clinical investigation.
STAT3: An Emerging Therapeutic Target for Hepatocellular Carcinoma
Authors: Lee Carol , Cheung Siu Tim
Published: October 2019

Hepatocellular carcinoma (HCC) is a major global health problem and its treatment options have been limited. Signal transducer and activator of transcription 3 (STAT3) is a transcription factor important for various cellular processes. Overexpression and constitutive activation of STAT3 have been frequently found in HCC and associated with poor prognosis. Ample evidence has shown that STAT3 plays pivotal roles in the initiation, progression, metastasis and immune suppression of HCC. Thus, STAT3 has attracted attention as a novel therapeutic target in HCC. Clinical trials have investigated STAT3-targeted therapeutics either as monotherapy or in combination with chemotherapeutic agents, immune checkpoint inhibitors and alternative targeted drugs. Some of these studies have yielded encouraging results. Particularly, napabucasin—a cancer stemness inhibitor targeting STAT3-driven gene transcription—has stood out with its promising clinical efficacy and safety profile. Nonetheless, clinical investigations of STAT3-targeted therapies in HCC are limited and more efforts are strongly urged to evaluate their clinical performance in HCC. Here, we provide a comprehensive review of the roles of STAT3 in HCC and follow by comprehensive analysis of STAT3 targeted strategies.

The aim of this study is showing the filming and skin barrier protective properties of a new ingredient based on ceramides and trehalose and carried in lipophilic vesicles composed of lecithin and cholesterol (or phytosterols). Through an in vivo study, the restructuring and hydrating properties of this trehalose and ceramides compound have been evaluated. Furthermore, this new ingredient has been used in a topical formulation for atopic dermatitis, proving to be effective in the alterations of skin barrier. This evidence makes it an interesting ingredient for topical dermatological compositions in the treatment of dermatitis and all manifestations correlated to these skin disorders, such as edema, swelling, rash, redness, and itching. Its soothing and protective action against the painful and annoying symptoms like those given by dermatitis makes this trehalose and ceramides based ingredient for topical use.

Background: The effects of publishing case reports on journal impact factor and their impact on future research in pediatric dentistry has not been clearly evaluated yet. Aim. To assess the relevance and role of case reports in pediatric dentistry. Methods: A systematic review (PROSPERO registration number: CRD42018108621) of all case reports published between 2011 and 2012 in the three major pediatric dentistry journals was performed manually. Data regarding citations of each report were acquired from the Institute for Scientific Information database available online. The authors analyzed information regarding citations (number, percentage, and mean) received by each case report and considered their relation with the 2013 journal impact factor. Results: Case reports accounted for almost sixteen per cent of all articles published between 2011 and 2012. The citation rate of case reports was generally low and the highest mean citation was 0.5. This review revealed that 6 (9.52%) case reports had at least 5 citations and that the majority of the citing articles were also case reports (27.78%) or narrative reviews (25%). Conclusions: The publication of case reports affected the journal impact factor in a negative way, this influence is closely related to the percentage of the published case reports. Case reports about innovative topics, describing rare diseases, syndromes, and pathologies were more frequently cited.

Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space. Usually, availability is shown as the coefficient of time use of the machine. This approach is not good enough because it does not go into the structure of the availability itself and requires a high level of IT support in system monitoring. In this sense, this paper will use the fuzzy theory and the corresponding analytic hierarchy process (AHP) multi-criteria analysis to present a conceptual and mathematical model for the assessment of availability based on expert judgment. The model will be shown in the case study (on the example) of bulldozers working in the open-pit lignite mine.

Published: October 2019

Photovoltaic (PV) system inverters usually operate at unitary power factor, injecting only active power into the system. Recently, many studies have been done analyzing potential benefits of reactive power provisioning, such as voltage regulation, congestion mitigation and loss reduction. This article analyzes possibilities for loss reduction in a typical medium voltage distribution system. Losses in the system are compared to the losses in the PV inverters. Different load conditions and PV penetration levels are considered and for each scenario various active power generation by PV inverters are taken into account, together with allowable levels of reactive power provisioning. As far as loss reduction is considered, there is very small number of PV inverters operating conditions for which positive energy balance exists. For low and medium load levels, there is no practical possibility for loss reduction. For high loading levels and higher PV penetration specific reactive savings, due to reactive power provisioning, increase and become bigger than additional losses in PV inverters, but for a very limited range of power factors.

Dramatic changes of forests have strong influence on regional and global carbon cycles, biodiversity, and ecosystem services. Understanding dynamics of forests from local to global scale is crucial for policymaking and sustainable development. In this study, we developed an updating and object-based image analysis method to map forests in Northeast China using Landsat images from 1990 to 2015. The spatio–temporal patterns of forests were quantified based on resultant maps and geospatial analysis. Results showed that the percentage of forested area occupying the entire northeast China was more than 40%, about 94% of initial forest cover remained unchanged (49.37 × 104 km2) over the course of 25 years. A small net forest loss (1051 km2) was observed during 1990–2015. High forest gain (10,315 km2) and forest loss (9923 km2) both occurred from 2010 to 2015. At the provincial level, Heilongjiang demonstrated the highest rate of deforestation, with a net loss of 1802 km2 (0.89%). Forest changes along elevation, slope, and distance from settlements and roads were also investigated. Over 90% of forest changes occurred in plains and low mountain areas within the elevation of 200–1000 m and slope under 15°. The most dramatic forest changes can be found within the distance of 2000 m from settlements and roads. The reclamation of sloping land, construction of settlements and roads, and possible smallholder clearing contributed more to forest loss, while ecological projects and related government policies play an important role on afforestation and reforestation. These results can provide useful spatial information for further research on the driving forces and consequences of forest changes, which have critical implications for scientific conservation and management of forests.

Spruce stands in the mountains of Central Europe are particularly valuable, not only because of their natural and scenic values but also because of their role in the protection of watersheds and soil. Over the past decades, these stands were frequently exposed to massive deforestation caused by various biotic, abiotic and anthropogenic factors. The current health condition of spruce stands in the Eastern Sudetes shows that the next phase of deterioration of these stands has begun. Bearing in mind past experiences and the current situation in these mountain areas, it is particularly important to understand the processes and factors that may short-term (2012–2016) spruce health analyses based on the normalized difference red-edge index and RapidEye satellite imagery, which is being delivered annually. Aided by remote sensing data and Boosted Regression Trees, it was possible to determine the topographic and tree stand features having the greatest impact on the vitality of spruce in all analyzed areas during 2012–2016. As the results show, the highest impact on the value of the normalized difference red-edge index indicator comes from a height above sea level, age of stands, terrain slopes, and exposure. In various areas, these factors may affect the vitality of spruce to varying degrees but not always in the same way. Our models accurately explained 74–81% of the randomly selected input data (predicted 72–80% of the excluded data) for site A, 50–58% for site B (48–57% for tested data) and 54–70% for site C (52–69% for excluded data).
Pretreatment of Sweet Sorghum Bagasse for Ethanol Production Using Na2CO3 Obtained by NaOH Absorption of CO2 Generated in Sweet Sorghum Juice Ethanol Fermentation
Authors: Nghiem Nhuan P. , Toht Matthew J.
Published: October 2019

(1) Background: Commercial production of fuel ethanol currently uses sugarcane and corn as feedstocks. Attempts to develop other renewable feedstocks that are more abundant have led to lignocellulosic biomass, which requires pretreatment prior to enzymatic hydrolysis to generate fermentable sugars. One of the largest cost components of pretreatment is chemical cost. Ethanol fermentation also produces large quantities of CO2 as a co-product contributing to global warming. (2) Methods: Sweet sorghum has emerged as a potential new feedstock for ethanol production. In the present study, the CO2 produced in sweet sorghum juice (SSJ) fermentation was captured by absorption in 5 M NaOH. The resultant Na2CO3 solution was used for pretreatment of sweet sorghum bagasse (SSB), which is the solid residue in SSJ extraction. The pretreated SSB was fermented in SSJ to produce additional ethanol. (3) Results: CO2 absorption efficiency of 92.0% was observed. Pretreatment of SSB by the obtained Na2CO3 solution resulted in no loss of glucan and only 8.1 wt% loss of xylan. Ethanol yield from glucan in the pretreated SSB was 81.7% theoretical. (4) Conclusions: CO2 from SSJ fermentation captured as Na2CO3 could be used for efficient SSB pretreatment. Further study focusing on pretreatment process optimization is needed.
FaDe: A Blockchain-Based Fair Data Exchange Scheme for Big Data Sharing

Published: October 2019

In the big data era, data are envisioned as critical resources with various values, e.g., business intelligence, management efficiency, and financial evaluations. Data sharing is always mandatory for value exchanges and profit promotion. Currently, certain big data markets have been created for facilitating data dissemination and coordinating data transaction, but we have to assume that such centralized management of data sharing must be trustworthy for data privacy and sharing fairness, which very likely imposes limitations such as joining admission, sharing efficiency, and extra costly commissions. To avoid these weaknesses, in this paper, we propose a blockchain-based fair data exchange scheme, called FaDe. FaDe can enable de-centralized data sharing in an autonomous manner, especially guaranteeing trade fairness, sharing efficiency, data privacy, and exchanging automation. A fairness protocol based on bit commitment is proposed. An algorithm based on blockchain script architecture for a smart contract, e.g., by a bitcoin virtual machine, is also proposed and implemented. Extensive analysis justifies that the proposed scheme can guarantee data exchanging without a trusted third party fairly, efficiently, and automatically.
