- We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

- The shift toward digital offerings poses challenges for companies that are adapting their development process from creating physical products to new digital artifacts. The ways in which companies design physical products and their interaction with customers is not effective in the digital domain. This article outlines how Sorgenia, a fast-growing utility company in Italy, conceptualized and designed the mobile app its consumers use to access its services. The classical dimensions of the user experience (aesthetic, emotional, and symbolic) need to be layered and coordinated throughout the customer’s interaction with the app to make the underlying values emerge progressively. In doing so, customers can be guided to comprehend a digital artifact fully, overcoming the interpretive barriers caused by the lack of physicality.

- Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, Lambda CDM. This is motivated by a range of apparently serious theoretical issues, involving such questions as the cosmological constant problem, the particle nature of dark matter, the validity of general relativity on large scales, the existence of anomalies in the CMB and on small scales, and the predictivity and testability of the inflationary paradigm. In this paper, we summarize the current status of Lambda CDM as a physical theory, and review investigations into possible alternatives along a number of different lines, with a particular focus on highlighting the most promising directions. While the fundamental problems are proving reluctant to yield, the study of alternative cosmologies has led to considerable progress, with much more to come if hopes about forthcoming high-precision observations and new theoretical ideas are fulfilled.

- Overview: Online-based retailers have made competing in the physical retail industry increasingly challenging. Building strong experiences to differentiate from the online-based players is key to survival. Brands can leverage different forms of engagement, such as sensorial or cognitive ones, to support their customer experience. "Read, Eat, Dream" (RED), a new concept by LaFeltrinelli, the major Italian bookseller, is an example of how to create an "omni-experience" by leveraging customers' lifestyles. This article outlines how LaFeltrinelli conceptualized and implemented the RED concept and presents four key design elements central to creating an omni-experience. By creating an omni-experience, retailers can transform from fulfillment centers to spaces where customers can engage, which in turn increases the length of their visit and occasions for purchase. An omni-experience also establishes the retail store as a reference point for some customers' specific activities.

hi_class : Horndeski in the Cosmic Linear Anisotropy Solving System

- We present the public version of hi cl a ss (www . hiclass-code . net), an extension of the Boltzmann code CLASS to a broad ensemble of modifications to general relativity. In particular, hi cl a ss can calculate predictions for models based on Horndeski's theory, which is the most general scalar-tensor theory described by second-order equations of motion and encompasses any perfect-fluid dark energy, quintessence, Brans-Dicke, f( R) and covariant Galileon models. hi-class has been thoroughly tested and can be readily used to understand the impact of alternative theories of gravity on linear structure formation as well as for cosmological parameter extraction.
