where CL is the weight concentration of a trace element in the melt, C0 is the weight concentration of a trace element in the original cumulate source, F is the weight fraction of melt produced and D0 is the bulk distribution coefficient of the original solid material. The bulk distribution coefficient is calculated by multiplying each mineral partition coefficient with the fraction of that mineral in the source.
The thermal boundary layer structure of a terrestrial body mainly comprises of two parts; in the upper part (crust and upper mantle), heat is transported by conduction while convection dominates in the lower part (lower mantle), also called the convective boundary layer. In a steady state scenario and in the absence of heat-producing elements, heat flow is supposed to be constant in the conductive crust, suggesting a relatively constant temperature gradient for constant thermal conductivity. The calculated steady state heat flux at the base of the lithosphere may directly represent the surface heat flux (assuming no contribution of heat sources in crust and lithospheric mantle). Therefore, in the absence of heat-producing elements, the heat flow is calculated using the relationship between the depth and the mantle potential temperature70. We use here the steady state equation:

During our previous investigation, we decided to leave some of the websites, domain names and associated email addresses that deserved a closer look for later. Over the last months, we took a deeper dive, with a specific focus on the Commission to Study the Organization of Peace (CSOP).
From then on, we uncovered an entire network of coordinated UN-accredited NGOs promoting Indian interests and criticizing Pakistan repeatedly. We could tie at least 10 of them directly to the Srivastava family, with several other dubious NGOs pushing the same messages.
Our investigation led to the finding of 10 UN-accredited NGOs directly controlled by the Srivastava Group, which our full report introduces at length. Their common trait? The fact that they all rose from the ashes of real NGOs. Indian Chronicles effectively benefited from the track record of these organisations while pursuing their own agenda: discrediting Pakistan and promoting Indian interests at UN conferences and hearings.
Before it ceased to exist in 2007, the Canners International Permanent Committee (CIPC) was all about the canning industry. Its reincarnation does not seem so concerned with food anymore: It mostly dispatches Geneva-based students to the UN to talk about Pakistan, and even organised side events on human rights at the UN.
The organisations created by the Srivastava Group in Brussels organised trips for Members of the European Parliament (MEPs) to Kashmir, Bangladesh and the Maldives. Some of these trips led to much institutional controversy, as the delegations of MEPs were often presented as official EU delegations when they were in fact not travelling on behalf of the Parliament.
Essentially, our investigation details how the activities of a fake zombie-NGO and that of a fake specialised media can be repackaged, distorted and amplified by malicious actors to influence or disinform globally, using loopholes in international institutions and online search engines.
The actors behind EP Today and EU Chronicle registered 550+ domain names of NGOs, think-tanks, media, European Parliament informal groups, religious and Imam organizations, obscure publishing companies and public personalities. A non-negligeable proportion of domain names were bought in the context of the cyberwarfare with Pakistan, to cybersquat on domains that Pakistan might later wish to use.
Our investigation relied heavily on the analysis of websites and domain names, rather than online platforms. Much of what we uncovered could be found thanks to website domain names registration history and because many websites of Indian Chronicles were created at a time when malicious actors were less concerned with privacy. Nowadays, malicious actors register domain names and create websites anonymously, making detection more difficult. The regulatory discussion on data transparency from platforms now taking place should be broadened to include greater scrutiny of domain names. Domain name information is critical for disinformation researchers; we therefore advocate for sufficient transparency for researchers investigating malicious domains. We also urge the domain name industry to seriously reflect on this kind of fraudulent, disinforming behaviour as technical abuse of the domain name system.
The fact is, we never intended to work on South-Asia related matters. It all began when we read a publication by the European External Action Service (EEAS) about EP Today syndicating content from RT. And this led us to publish these two investigations.
Let us bear in mind that it is not because one side uses dodgy influence campaigns that the other side does not: A simple Google search will lead you to read about inauthentic behaviours supporting Pakistani interests.
Mr. Casaca indicates that some elements in our report are not substantiated. However, the findings in our report have been corroborated by international media such as BBC, Politico, Les Jours and Le Temps. Since publication, our report has been covered by more than 100 media across the world, including some of the most respected international media, who have analysed our work in-depth.
Mr. Casaca challenges the motives behind some of the elements in our report, suggesting that the EU DisinfoLab has a hidden agenda. We strongly denounce baseless assertions that we would be advancing a particular agenda. As a reminder, we have published investigations on various topics and regions. This is clearly explained by Pratik Sinha, an Indian fact-checker at Alt news: _thinker/status/1337416413904945153?lang=en.
It should be noted that Mr. Casaca does not contest that the domain name
sadf.eu was registered by csopus[at]
yahoo.com, a central email address used by Indian Chronicles to register many domain names and covered extensively in our report.
With regards to the other points raised by Mr. Casaca, we stand firmly by the findings detailed in our report. We encourage anyone interested in learning more about this 15-year influence operation targeting the EU and the UN to read it in full.

The formation, maintenance and the fine-tuning of synaptic connections between neurons is an essential part of brain function. These processes are modulated by a wide range of extracellular stimuli and are orchestrated through the regulation of synaptic proteins and key signalling pathways. Increasing evidence have also linked mutations or altered expression of synaptic proteins and signalling molecules are linked with neurodevelopmental and psychiatric disorders. Thus, understanding how synapses are formed and respond to different stimuli, and the exact role specific synaptic proteins play will help us better understand brain function in physiology as well as in specific disorders.
The main goal of the Srivastava Lab is to develop an in-depth understanding of the molecular mechanisms that underlie synaptic function in physiology, but also dysfunction in the context of neurodevelopment and psychiatric disorders. We specifically focus on elucidating the molecular mechanisms underlying the formation and remodelling of synapses, and how extracellular signals regulate these processes. Moreover, we are particularly interested in how genes associated with increased likelihood of developing neurodevelopmental and psychiatric disorders contribute to the control of synaptic structure, function and trafficking of proteins to and from synaptic compartments. To achieve this, we utilize cutting-edge technologies such as patient derived induced pluripotent stem cells (iPSCs) as well as advanced cellular imaging approaches. We work closely with basic and clinical colleagues as well as pharmaceutical companies to address these questions.
