Which is the best software tool for plotting growth charts?

As Editorial member of peer reviewed journals, I have been alerted to a new malpractice in the area of scientific publications. Currently, an increasing number of journals have been targeted by some organisations that aim to manipulate the peer review process, known as paper mills. What’s a paper mill? A paper mill is an organisation that offers services to individuals that include: - Writing a manuscript on their behalf and submitting to a journal of their choice; - Writing a manuscript which the paper mill submits to a journal, which when accepted, they sell the authorship of (with varying fees depending on the order of the author); - Writing an article which an individual will pay to add superfluous references to, in order to boost their citation score; - Installing reviewers into a journal site, who commit reviewer fraud. Paper mills operate globally, and there are academics from across the world involved. Papers can be perfectly acceptable research papers, or they may be research papers where the research was never conducted, or they do not make sense to the reader. There are procedures to prevent paper mill activities; however, it is our responsibility, as member of the research community, to engage in ethical behavior, and to promote fairness and rigor in research and dissemination activities.

Anyone kindly please suggest tools for the same. I have distance matrix file and want to generate phylogenetic tree on the basis of that.

It will be appreciating if someone suggest any tool which can generate phylogenetic tree without alignment. In the same context I used AAF (Alignment and Assembly Free: tool for phylogenetic tree) but it is having some issue with C library and can only generate distance matrix and unable to build the tree.

Thanks

I used to think they were the same thing until today, I found out they are now different.

More and more researchers are worried about the rumours regarding the possibility of a general exclusion of articles published in MDPI journals to assess research careers. Is this happening in your country? In Spain, the discussion is already being held by several commissions in charge of assessing researchers' productivity and Cvs.

Let's suppose there's an ecology investigation going on. The most relevant species of insects in a mountain range should be sequenced because they want to make a phylogenetic tree using bioinformatics software. How much would cost the sequencing at a decent quality, for each insect? Is it still too expensive to try something like sequencing the genomes of the 1000 more relevant species of an area?

Dear All,

Received an honorary nomination and invitation to join Sigma Xi, The Scientific Research Honor Society as a full member. Should I join this society? Is it a legit platform?

Please share your thoughts on this,

Can anyone suggest me how to do this standardization curve?

I am thinking to either using a method where I set time points and at each time point, I read the OD600 along with doing serial dilution and plating on agars OR pick one time point and serially dilute it so I have several diluted bacteria (read OD600 each of them) then each of these goes to serial dilution and plating on agars.

If someone can suggest me other methods. I really appreciate it.

I want to refer to this curve whenever I need to know the concentration of the killed bacteria.

Required sample size for validation of my study

When we have two groups with pre and post-test data, which test is better? One-way analysis of covariance (ANCOVA) or Repeated Measures Analysis of Variance (RM-ANOVA)? Why?
