Amplitude equations for systems with long-range interactions

We derive amplitude equations for interface dynamics in pattern forming systems with long-range interactions. The basic condition for the applicability of the method developed here is that the bulk equations are linear and solvable by integral transforms. We arrive at the interface equation via long-wave asymptotics. As an example, we treat the Grinfeld instability, and we also give a result for the Saffman-Taylor instability. It turns out that the long-range interaction survives the long-wave limit and shows up in the final equation as a nonlocal and nonlinear term, a feature that to our knowledge is not shared by any other known long-wave equation. The form of this particular equation will then allow us to draw conclusions regarding the universal dynamics of systems in which nonlocal effects persist at the level of the amplitude description.Comment: LaTeX source, 12 pages, 4 figures, accepted for Physical Review

Patient satisfaction with calcipotriol/betamethasone dipropionate cutaneous foam for the treatment of plaque psoriasis: The LION real-life multicenter prospective observational cohort study

Topical treatment is the mainstay for mild or moderate psoriasis, but patients are generally little satisfied. Calcipotriol/betamethasone dipropionate (Cal/BD) cutaneous foam has shown to improve signs and symptoms in plaque psoriasis patients. This study assessed patient's satisfaction with Cal/BD foam in a real-life Italian dermatological clinical practice. A multicenter, 4-week observational prospective cohort study enrolled, in 17 Italian dermatology clinics, adult patients with plaque psoriasis on the body and/or scalp. Treatment satisfaction was assessed by 9-item Treatment Satisfaction Questionnaire for Medication (TSQM-9), preference over previous treatments by Patient Preference Questionnaire (PPQ), and change in disease state by Psoriasis Area Severity Index (PASI). Overall 256 patients were eligible, with a mean (SD) age of 55.6 (15.4) years, 59.4% were males. Psoriasis severity was mild in 52.0% of patients, moderate in 43.3%, and severe in 4.7%. Scalp involvement was present in 36.7% of patients. Previous antipsoriatic treatments had been received by 80.5% of patients. TSQM-9 median (25th–75th percentile) scores were 83.3 (66.7–88.9) for effectiveness, 77.8 (66.7–88.9) for convenience, and 78.6 (64.3–92.9) for global satisfaction. Mean (SD) PASI value decreased from 7.3 (4.8) to 2.1 (2.7) after 4 weeks. More than 90% of patients previously treated for psoriasis evaluated the Cal/BD foam more effective, easier to use and better tolerated compared to previous topical treatments at PPQ. This observational study provides real-life evidence of a high level of satisfaction with effectiveness and convenience of the Cal/BD foam in a cohort of plaque psoriasis patients, with an objective improvement in PASI

Root polytopes and abelian ideals

We study the root polytope $\mathcal P_\Phi$ of a finite irreducible crystallographic root system $\Phi$ using its relation with the abelian ideals of a Borel subalgebra of a simple Lie algebra with root system $\Phi$. We determine the hyperplane arrangement corresponding to the faces of codimension 2 of $\mathcal P_\Phi$ and analyze its relation with the facets of $\mathcal P_\Phi$. For $\Phi$ of type $A_n$ or $C_n$, we show that the orbits of some special subsets of abelian ideals under the action of the Weyl group parametrize a triangulation of $\mathcal P_\Phi$. We show that this triangulation restricts to a triangulation of the positive root polytope $\mathcal P_\Phi^+$.Comment: 41 pages, revised version, accepted for publication in Journal of Algebraic Combinatoric

The new Italian SIDAPA Baseline Series for patch testing (2023): an update according to the new regulatory pathway for contact allergens

Allergic contact dermatitis (ACD) is a common inflammatory skin disease caused by delayed hypersensitivity to chemical and biotic contact allergens. ACD significantly affects the patients' quality of life negatively impacting both occupational and non-occupational settings. Patch testing is the gold standard diagnostic in vivo test to precise the ACD etiology and to correctly perform prevention. According to the Italian Medicines Agency (AIFA) legislative decree no. 178 of 29th May 1991, allergens are defined as medicines and therefore they are subject to strict regulation. In 2017, AIFA (decree no. 2130/2017) started a procedure to regulate contact allergens on the Italian market and actually the contact allergens temporarily authorized are reported in AIFA decree no. 98/2022, valid until November 2023. The availability on the market of contact allergens to diagnose ACD and continuous updating on the basis of new epidemiological trends are mandatory, jointly with the continuous update of the baseline and integrative series for patch testing. For this reason, the scientific community represented in Italy by the Skin Allergies Study Group of SIDeMaST (Italian Society of Dermatology and Venereology) and SIDAPA (Italian Society of Allergological, Occupational and Environmental Dermatology) are constantly working, in close relationship with the European scientific communities with large expertise in this important sector of the modern Dermatology. Herein, we report the setting up of regulatory legislation by AIFA and the new Italian Adult Baseline Series for patch testing

AtopyReg®, the Prospective Italian Patient Registry for Moderate-to-Severe Atopic Dermatitis in Adults: Baseline Demographics, Disease Characteristics, Comorbidities, and Treatment History

background and objective atopyReg((R)) is a multicenter, prospective, observational, non-profit cohort study on moderate-tosevere atopic dermatitis in adults promoted in 2018 by the Italian society of dermatology and Venereology (SIDeMaST). we aimed to describe baseline demographics, disease characteristics, comorbidities, and therapeutic data of adult patients affected by moderate-to-severe atopic dermatitis.methods patients were selected based on the following inclusion criteria: age >= 18 years; eczema area and severity Index score >= 7 or a numeric rating scale sleep loss score = 7, or a dermatology life quality Index score >= 10. score >= 16 or localization in visible or sensitive areas (face, neck, hands, or genitalia), or a numeric rating scale itchDemographic and clinical data at baseline were recorded and analyzed. results a total of 1170 patients (male 51.1%; mean age: 44.7 years; range 18-90 years) were enrolled by 12 Italian dermatology units between January 2019 and november 2022. skin lesions were eczematous in 83.2% of patients, the most involved site were the flexures (53.9%), face (50.9%), and neck (48.0%). mean eczema area and severity Index score was 22.3, mean dermatology life quality Index value was 17.6, mean patient oriented Eczema measure score was 13.1, and mean numeric rating scale itch and sleep loss scores were 7.6 and 5.9, respectively. previous systemic therapies were corticosteroids in 77.7% of patients, antihistamines in 50.3% of patients, and cyclosporine A in 42.6% of patients.conclusions this baseline data analysis deriving from atopyReg((R)) provides real-life evidence on patients with moderate-to-severe atopic dermatitis in Italy confirming the high burden of atopic dermatitis with a significant impact on patients' quality of life

A Non-Linear Statistical Model for GaAs FET Integrated Circuits

A new statistical non-linear model of GaAs FET MMIC’s which allows to represent distance-dependent technological parameter variations by means of equivalent circuit parameters is presented. An automatic procedure to extract the statistical model parameters from a database of DC and S-parameter measurements has been developed. The procedure performs the extraction of the covariance matrices of two FET devices at different mutual distances and uses them to build the multi-device MMIC covariance matrix. Capability to reproduce statistical distribution has been successfully checked by performing hypothesis tests of equivalence on S-parameters at different distances in the 1-5 GHz frequency range
