Dinosaurs and Cancer: A Podcast

Cancer is a dreadful disease. In some ways, it is actually a disorder or malfunction of the body. While its details are still fuzzy, considering the large number and types of cancer, it appears as an emergence resulting from a lack of coordination of various systems inside the body.

Scientists have always been looking for the origins of Cancer. Recently they have found concrete proof of cancer existence in animals dating back to the dinosaurs.

David Evans, senior curator of Paleontology at the Royal Museum of Ontario in Toronto has identified bone cancer from a so-called “Centrosaurus” dinosaur from around 7075 million years ago.

The study has been presented in the journal Lancet Oncology [1].

Emily Schwing from the Scientific American presents a podcast on this interesting topic.


Hubble and the Moon

To the best of our current knowledge, moon is the only natural “official” satellite orbiting our planet.

This, however, has often been challenged by some researchers over time who call some near-earth objects with synchronized orbits as “second moons” [1, 2].

While a number of these observations have been discarded by the scientific community, there still are objects which include temporary satellites, quasi-satellites, trojans, horseshoe orbit objects and more.

This is actually an exception in the solar system with 70 known moons for Jupiter.

The Hubble telescope took this splendid shot of our moon in 1991.

Climate Scientists Reaffirm the Importance of Simple Models

Background Complex Adaptive Systems involve a large number of variables. These variables are essentially inputs from complex processes which can often be modeled as agents. The data generated from these systems can be considerably nonlinear and difficult to understand.

Problem Statement In systems which are very closely linked to the human world, often times, there is a need to make quick or at least, expensive decisions in a relatively shorter amount of time.

Research Outcome The presented research reaffirms the belief of the Complex Adaptive Systems (CAS) community that simpler models can be considerably better in terms of making decisions.

Exploring Local Covid-19 Cases Using Google Maps!


Google has been successfully able to demonstrate the effective use of real-time data in its apps. They have been adding new content and capabilities. In a recent blog post, Google has introduced a yet another capability in Google Maps which will be showing location-specific Covid-19 data.


In the past, google has been adding new and innovative data-centric mechanisms to its suite of apps. These have included features such as:

So, now Google Maps is adding an additional layer inside it which will use color-coding.

How to?

It is not hard to use. Simply speaking, you need to tap on the layers button (Typically showing up at the top right corner) and then click on the Covid-19 info.

What you will see next is the data of new cases per 100,000 people in the area – averaged over a seven day period for normalization purposes. This data is available for 220 countries and regions supported by Google Maps. It can even allow for drilling down to a particular region or city.

What is new?

Arguably, country and region-wide data on Covid-19 cases has already been available for a considerable time. However, what is new here is the integration of Google maps with the data. This opens up new avenues for conducting research, for health authorities to explore regions visually, or simply if you just want to be the smart-citizen by understanding how the spread is occurring. It adds on to existing google apps such as those helping to get around safely.

What is Missing?

While interesting, the data is just one aspect of the big picture. For one, the data presented seems to be instantaneous (i.e. non-temporal). In other words, we cannot explore trends and gradients by simply looking at the map. It also does not show recoveries, or information about local facilities such as hospitals. While there may be existing, localized apps for that, to my knowledge, there is no direct, public integration of any of these apps with Google maps.


Call for Papers: JOURNAL OF SIMULATION (JoS) SPECIAL ISSUE ON “Modeling and Simulation in the Cloud Computing era”

JOURNAL OF SIMULATION (JoS) SPECIAL ISSUE ON “Modeling and Simulation in the Cloud Computing era”



Cloud computing has received considerable interest by the scientific and industrial community because, thanks to advances in Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), it allows the implementation of solutions to exploit computing and data storage capacity, network resources, and scalability rapidly. In this context, Cloud, Edge and Fog computing can offer suitable services to share and collaborate on M&S and perform complex simulation experiments faster and more efficiently using Modelling and Simulation as a Service (MSAAS). While MSAAS offers an ever-expanding number of possibilities, it also entails a considerable number of challenges. One of the key challenges is related to the fact that cloud infrastructures are massive at all scales, therefore developing MSAAS solutions is difficult without an adequate knowledge of the involved platforms and technologies.

The aim of this special issue is to provide a comprehensive guide on current ideas and results in M&S for Cloud computing and vice versa. Specifically, the issue aims at: (i) presenting the current state-of-the-art about M&S environments and frameworks based on open standards, recent extensions, and innovations related to Cloud computing technologies; and, (ii) identifying potential research directions and technologies that will drive innovations in M&S on Cloud Computing Infrastructures. Additionally, the special issue will also look for submissions employing Complex Systems related methodologies, toolkits, and frameworks such as involving Complex Social Networks, and Agent-based Modelling, among others.

Nowadays, there is research aiming at investigating the impact of Cloud computing on M&S techniques and methodologies. We believe that a journal special issue on “Modeling and Simulation in the Cloud Computing era” will be a timely contribution to a field that is gaining considerable research interest and is expected to be of increasing interest to commercial developers in a wide range of application domains. Moreover, we believe that the methodological and technological trends in the convergence of Cloud Computing and M&S disciplines need to be explored more in order to provide an exclusive research roadmap to both Cloud Computing and M&S communities. Furthermore, this special issue involves strongly scientific programming aspects related to mathematical models and quantitative analysis techniques that use heavily cloud computing solutions.

Manuscripts for the Special Issue must provide a novel contribution and must be carefully placed in relation to the relevant scientific literature. Authors clearly address research issues of M&S in the Cloud and show the use of existing methodologies, techniques, and tools for the development of future-generation of simulators based on Cloud computing services.

Topics of interest include, but are not limited to:

– High-performance simulation in the Cloud;

– Cloud-based parallel and distributed simulation;

– Simulation optimization approaches that leverage Cloud Computing;

– Dependability and performance analyses through Big data in the Cloud;

– Hybrid modelling research that combines the application of Cloud-based solution to one or more stages of a simulation study;

– Real-time simulations in the Cloud;

– Application-focused papers that also contribute to methodology;

– Literature review (invited; please contact the Guest Editors with a proposal);

– Invited viewpoint papers (invited; please contact the Guest Editors with a proposal).



Manuscripts should be submitted online through the Journal of Simulation (JoS) ScholarOne system at:  https://mc.manuscriptcentral.com/ors-jos

Github and Unity for Teams: Part 3

Oddly enough, odd numbers can be not only interesting but also quite satisfying – perhaps simply because they are so odd. 🙂

So, here we have our second odd-numbered post (Post number 3) on Github and Unity.

In the third part of the series, I try to present some suggestions on using #Github with #Unity3D in Team Projects. I also briefly take a look on how I worked with my students/team members in handling #internet connectivity issues.

Additionally, I present a possible workflow for using Github and Unity (2019.3 or later) together in remote teams/student project scenarios.

Turing Machines & their Components

One of the key machines used in the “Theory of Computation” subject is the “Turing Machine”. Turing machine is currently, possibly, the most advanced model capable of being able to connect with a large number of possible languages. This is besides its ability to simulate modern computer systems and algorithms.

Hill Climbing Search in Artificial Intelligence

Hill-climbing search is one of the key search algorithms used in Artificial Intelligence.

The idea behind this search is to look for points based on the current location. So, if we have a data point D with a certain number of values V, the way it works is to somehow look for better points based on small variations in the different values.
