How I treat acne scars?

The approach to managing acne scars is unique to every dermatologist. This depends on the skin type of his/her clientele, the tools, techniques and devices available and/or used, and the protocols developed based on his/her experience with treating acne scars, developed over a period of time. Herein, we share our algorithmic treatment approach to acne scars, which allows for a consultative decision-making together with the patient, while offering adequate flexibility to modify the plan based on treatment response. Eventually, a customized and comprehensive system works best, and a partnership approach signified by a robust self-care home plan, helps accelerate the scar revision process.

Computational Multiscale Solvers for Continuum Approaches

Computational multiscale analyses are currently ubiquitous in science and technology. Different problems of interest—e.g., mechanical, fluid, thermal, or electromagnetic—involving a domain with two or more clearly distinguished spatial or temporal scales, are candidates to be solved by using this technique. Moreover, the predictable capability and potential of multiscale analysis may result in an interesting tool for the development of new concept materials, with desired macroscopic or apparent properties through the design of their microstructure, which is now even more possible with the combination of nanotechnology and additive manufacturing. Indeed, the information in terms of field variables at a finer scale is available by solving its associated localization problem. In this work, a review on the algorithmic treatment of multiscale analyses of several problems with a technological interest is presented. The paper collects both classical and modern techniques of multiscale simulation such as those based on the proper generalized decomposition (PGD) approach. Moreover, an overview of available software for the implementation of such numerical schemes is also carried out. The availability and usefulness of this technique in the design of complex microstructural systems are highlighted along the text. In this review, the fine, and hence the coarse scale, are associated with continuum variables so atomistic approaches and coarse-graining transfer techniques are out of the scope of this paper.

Digital Platforms: A New Grammar for Territories?

Digital platforms are reshaping the geometry of the world. Their wide adoption by the population worldwide for an increasing number of activities, confer them a dominant position, which challenges established powers. Their control over the global flow of data and their algorithmic treatment leads to new asymmetries of power. New systems emerge, that unlike the Westphalian States do not correspond to territories on a map, but to complex networks controlling sectors of activities at a global scale. It is a real challenge and a necessity to reinvent a grammar of territories, to be able to grasp the new objects and their dependencies, and address the related issues of social justice and sustainable interaction with our planet.

Low-tech security: Files, notes, and memos as technologies of anticipation

When it comes to anticipating terrorism, do recent technological advancements fundamentally change the modus operandi of intelligence services? Recent scholarship has focused on the new modes of reasoning brought about by ‘hi-tech’ forms analysis such as data mining, graph visualization and the algorithmic treatment of big data. While this article recognizes the increasing influence of these techniques, it argues they should not overshadow much more low-tech modalities through which a large part of counterterrorism work takes place. Low-tech counter-terrorism, based on qualitative methods and conjectural reasoning, still matters. Drawing on the case of French domestic intelligence services and based on qualitative interviews, observations and declassified documents, this article shows that the practices of security professionals, rooted in traditional institutional habituses developed over time, are largely in continuity with previous ‘low-tech’ forms of police work. In a context in which the uses of digital security technologies have generated discussions about politics and ethics, this article suggests that traditional techniques of intelligence gathering and processing therefore still merit a great amount of attention.
