向天然气管道中注入乙二醇并进行回收再利用是深水气田开发中防止水合物生成的重要技术手段，但当采出水中的二价盐含量较高时会造成管道或MEG 再生系统的堵塞、结垢和腐蚀等问题，导致常规乙二醇再生系统不能正常生产。为此开发了一种新的乙二醇再生工艺，即在MEG 富液中加入碱液使M2+生成沉淀物，然后采取过滤分离的方式脱掉二价盐再进行再生。通过室内模拟实验，对富乙二醇中二价阳离子脱除影响因素和操作条件进行了研...
Conversational Interaction in the Scanner: Mentalizing during Language Processing as Revealed by MEG
conversational interaction episodic working memory
2015/12/18
Humans are especially good at taking another’s perspective—representing
what others might be thinking or experiencing. This “mentalizing”
capacity is apparent in everyday human interactions and conv...

Subjects (n=12) listened to the synthesized syllable tokens ba, da, ma, and na. Evoked magnetic fields were recorded using a 93-sensor whole-head biomagnetometer array while subjects performed a same-...
The role of temporal predictability in semantic expectation: An MEG investigation
Prediction Expectation Semantic
2015/9/2
Prior research suggests that prediction of semantic and syntactic information prior to the
bottom-up input is an important component of language comprehension. Recent work in
basic visual and audito...
A lexical basis for N400 context effects: Evidence from MEG
Semantic priming Semantic anomal Prediction
2015/9/2
The electrophysiological response to words during the ‘N400’ time window (300–500 ms post-onset) is
affected by the context in which the word is presented, but whether this effect reflects the ...

"Are we still talking about the same thing?" MEG reveals perspective-taking in response to pragmatic violations, but not in anticipation
Are we still talking about the same thing MEG pragmatic violations not in anticipation
2015/4/27
The current study investigates whether mentalizing, or taking the perspective of your interlocutor, plays an essential role throughout a conversation or whether it is mostly used in reaction to misund...
Adding dynamics to the Human Connectome Project with MEG
Magnetoencephalography (MEG) Connectome Processing pipeline Functional connectivity

Magnetoencephalographic (MEG) recordings are a rich source of information about the neural dynamics underlying cognitive processes in the brain, with excellent temporal and good spatial resolution. In...
Lateralization of tonal and intonational pitch processing: An MEG study
Pitch Tone Intonation MEG
2015/4/9
An MEG experiment was carried out in order to compare the processing of lexical-tonal and intonational contrasts, based on the tonal dialect of Roermond (the Netherlands). A set of words with identica...
Investigating phonological processing by varying pronounceability: MEG Evidence
Investigating phonological processing varying pronounceability
2014/11/12
For words and pronounceable non-words, the M350 did appear to be inversely related to word frequency, as found in previous studies (Embick et. al., 2001). We did, however, find an M350 peak for the f...

2013/6/14
We describe a novel Bayesian approach to the estimation of neural currents from a single distribution of magnetic field, measured by magnetoencephalography. We model neural currents as an unknown numb...
