Introduzione
No full textIl tema dell'interno in architettura si configura oggi come un ambito di indagine ampio e complesso, difficile da affrontare secondo un approccio disciplinare rigido e classificatorio. I saggi che compaiono in questa raccolta costituiscono una sequenza incalzante di scritti, che spaziano dai luoghi per l'arte all'interno domestico, dalla period-room all'allestimento interattivo, dal paesaggio sonoro al paesaggio mediatico e si confrontano con questioni quali temporaneità, nomadismo, mobilità e transitorietà. Il respiro con cui viene trattato ogni argomento denuncia la sua appartenenza ad più ampio progetto culturale, che muovendosi nella eterogeneità dei discorsi, riafferma nuovi possibili statuti di senso.

Inhabited Images: Drawing a New Life for Housing Complexes
No full text[EN] The theme of inhabiting in high-density buildings has been widely investigated since the Mid-Twentieth century. Still, original researches are now opening new perspectives, creating a common ground in which urban planning and architecture increasingly intersect with studies based on participation, urban policies and spatial justice. The failure of some of the iconic Twentieth-century architectures rose a strong debate that often resulted in their demolition. This process was primarily dictated by market logic, by a change in the residents and, above all, by the lack of all the services needed to build a community. Some experimental alternatives to replacing neglect building complexes have emerged especially in France and Northern Europe. The paper presents a selection of residential projects by Lacaton & Vassal, Mikhail Riches and LAN (Local Architecture Network), which use architectural drawings to propose innovative solutions to local administrations, as well as to initiate planning processes involving resident communities.Cristina F.

Synthesis of Unnatural Alfa-N-linked Glycopeptides with Potential Antifreeze Activity
No full textThe synthesis of neo-glycoconjugates has been gaining much attention in recent years due to the relevance of glycopeptides and glycoproteins in many biological processes.[i] Our group has been actively dedicating its efforts to the synthesis of α-N-linked glycosylamides and glycopeptides.[ii] α-N-linked glycopeptides are unnatural molecules, since they display an α linkage between the peptide side chain and the sugar moiety, unlike natural glycopeptides which connect the peptide to the glycan through a β-N-glycosidic bond. This novel type of glycosylation of peptides could introduce modifications that can mimic and/or interfere with molecular recognition events.[iii] Direct glycosylation of peptide chains is not viable for the synthesis of molecules with α-N-linked configuration, since the corresponding α-glycosyl amines isomerise to the β-anomers. Only very recently Nα-Fmoc-protected glycosyl amino acids have been efficiently and stereoselectively synthesized and linearly incorporated into a peptide sequence.[iii] In the present paper these novel building blocks have been employed for the synthesis of complex structures that resemble antifreeze glycopeptides (Figure 1).[iv] These sequences were prepared using solid phase synthesis with Fmoc protocol, experimenting with different conditions and also using microwave assisted solid phase synthesis, in an effort to enhance the reactivity of our unnatural building block. The α-N-linked glycopeptides were obtained with modest yields, their secondary structure was assessed by circular dichroism and their antifreeze properties were evaluated in the group of Prof. Robert N. Ben. Despite the fact that our compounds do not show significant antifreeze activity, this work constitutes the first attempt towards the synthesis of complex α-N-linked glycopeptides and has been useful to understand the behaviour, sometimes unexpected, of these molecules, in terms of reactivity and stability.

Towards a general F-resolvent equation and Riesz projectors
No full textThe Fueter-Sce-Qian mapping theorem is a two steps procedure to extend holomorphic functions of one complex variable to quaternionic or Clifford algebra -valued functions in the kernel of a suitable generalized Cauchy-Riemann operator. Using the Cauchy formula of slice monogenic functions it is possible to write the Fueter-Sce-Qian extension theorem in integral form and to define the F-functional calculus for n-tuples of commuting operators. This functional calculus is defined on the S-spectrum and generates a monogenic functional calculus in the spirit of McIntosh and collaborators. One of the main goals of this paper is to show that the F-functional calculus generates the Riesz projectors. The existence of such projectors is obtained via the F-resolvent equation which was previously known only in the quaternionic setting and also its existence was under question. In this paper we prove the F-resolvent equation in the Clifford algebra setting. It is much more complicated than the one in the quaternionic case since it contains various pieces, however it still allows to nicely define the Riesz projectors. (C) 2022 Elsevier Inc.

Superoscillating Sequences and Supershifts for Families of Generalized Functions
No full textWe construct a large class of superoscillating sequences, more generally of F-supershifts, where F is a family of smooth functions in (t, x) (resp. distributions in (t, x), or hyperfunctions in x depending on the parameter t) indexed by λ ∈ R. The frame in which we introduce such families is that of the evolution through Schrödinger equation (i∂/∂t−H (x))(ψ) = 0 (H (x) = −(∂2/∂x2)/2+V (x)), V being a suitable potential). If F = {(t, x) → ϕλ(t, x) ; λ ∈ R}, where ϕλ is evolved from the initial datum x → eiλx , F-supershifts will be of the form {Nj =0 Cj (N, a)ϕ1−2 j/N }N≥1 for a ∈ R\[−1, 1], taking Cj (N, a) = Nj (1 + a)N−j (1 − a) j /2N . Our results rely on the fact that integral operators of the Fresnel type govern, as in optical diffraction, the evolution through the Schrödinger equation, such operators acting continuously on the weighted algebra of entire functions Exp(C). Analyzing in particular the quantum harmonic oscillator case forces us, in order to take into account singularities of the evolved datum that occur when the stationary phasis in the Fresnel operator vanishes, to enlarge the notion of F-supershift, F being a family of C∞ functions or distributions in (t, x), to that where F is a family of hyperfunctions in x, depending on t as a parameter
