Abstract The fast information sharing on Twitter from millions of users all over the world leads to almost real‐time reporting events. It is extremely important for business and administrative decision makers learn events' popularity as quickly possible, it can buy extra precious time them make informed decisions. Therefore, we introduce problem predicting future trend events microblogging platforms. Traditionally, prediction has been performed by using series analysis past forecast changes....

Abstract A bismuth(III) bromide‐catalysed direct substitution of benzyl alcohols with arylsulfonylmethyl isocyanides affords sulfinates under mild acidic conditions. An unforeseen reversed reactivity was observed in this highly selective formation instead the usually favoured sulfones. Cytotoxicity tests ( vitro ) indicated that exhibit antibiotic activity against a human leukaemia cell line HL‐60, which would widen structural diversity antitumour target and confirm perspectives further...

Community formation analysis of dynamic networks has been a hot topic in data mining which attracted much attention. Recently, there are many studies focus on discovering communities successively from consecutive snapshots by considering both the current and historical information. However, these methods cannot provide us with or successive information related to detected communities. Different previous community detection networks, we define new problem tracking progression strength-a novel...

The credit card business has become an indispensable financial service for commercial banks. With the development of business, banks have achieved outstanding results in maintaining existing customers, tapping potential and market share. During operations, massive amounts data multiple dimensions—including basic customer information; billing, installment, repayment transaction flows; overdue records—are generated. Compared with preloan postloan links, user default prediction on-loan link a...

A copper-catalyzed formation of C–N/N–N bonds using <i>N</i>-phenylbenzamidines with aryl nitriles has been developed and affords a route to 1,3,5-trisubstituted 1<i>H</i>-1,2,4-triazoles in moderate excellent yields. The method is operationally simple environmentally benign large substrate scope available represents an economical path for numerous bond formations.

A vast ocean of data is collected every day, and numerous applications call for the extraction actionable insights from data. One important task to detect untrustworthy information because such usually indicates critical, unusual, or suspicious activities. In this paper, we study problem detecting a novel perspective correlating comparing multiple sources that describe same set items. Different existing work, recognize importance time dimension in modeling commonalities among sources. We...

Community formation analysis of dynamic networks has been a hot topic in data mining which attracted much attention. Recently, there are many studies focus on discovering communities successively from each snapshot by considering both current and historical information. However, the detected isolated at certain snapshot, because these approaches ignore important or successive Different previous community detection networks, we define new problem tracking progression strength - novel measure...

With the digital transformation of commercial banks and online transfer credit transactions, relationship between subjects tends to be complex, personal risk management is facing challenges. The contagiousness among are poorly understood in field management. This study used an SEIR infectious disease model reveal mode structure associated based on theory method complex networks, it explored status influencing factors a scale‐free network using simulation experiments. research findings...

Mediated by active metallic indium generated in situ from samarium and InCl 3 .4H 2 O, phenacyl bromide aldehydes smoothly underwent intermolecular aldol type reaction aqueous media affording β-hydroxy ketones good yields under mild conditions.

Bioinformatics computing is a kind of big data processing problem, which usually has the characteristics large scale, computational load and long time. Therefore, use technology in bioinformatics gradually become research hotspot, using Hadoop for gene sequence alignment one it. It common way to various tools complete job field Biocomputing. In most studies parallel sequences Hadoop, third-party are also needed. However, there few methods independently alignment. Adding with other workflow...

Mediated by active metallic indium generated in situ from Sm/InCl 3 .4H 2 O bimetallic system, aldehydes and allylic bromide undergo efficient Barbier-type allylation reaction to afford homoallylic alcohols high yields under mild conditions aqueous media.

Abstract An unexpected reversal of reactivity is observed to give sulfinates highly selectively instead the usual sulfones.

Abstract Various mono‐ and disubstituted 2,3‐dihydroquinazolinones (III) (V) are efficiently synthesized by a one‐pot three‐component reaction of isatoic anhydride, aromatic aldehydes, primary amines or ammonium salts.

Abstract The reaction is simply carried out by initial grinding for about 10 min followed heating the ground mixture.

Abstract The Cu(II)‐catalyzed one‐pot, three‐component cyclocondensation of isatoic anhydride, aromatic aldehydes, and ammonium salt or primary amines affords dihydroquinazolinone derivatives in excellent yields.

Abstract Three‐component condensation of isatoic anhydride with aromatic aldehydes and ammonium salts or primary amines is achieved using strontium chloride as the catalyst to give dihydroquinazolinones (III) (VI), resp., in good excellent yields.
