Asymptotic decay of solutions for sublinear fractional Choquard equations

Goal of this paper is to study the asymptotic behaviour of the solutions of the following doubly nonlocal equation $$(-\Delta)^s u + \mu u = (I_{\alpha}*F(u))f(u) \quad \hbox{on $\mathbb{R}^N$}$$ where $s \in (0,1)$, $N\geq 2$, $\alpha \in (0,N)$, $\mu>0$, $I_{\alpha}$ denotes the Riesz potential and $F(t) = \int_0^t f(\tau) d \tau$ is a general nonlinearity with a sublinear growth in the origin. The found decay is of polynomial type, with a rate possibly slower than $\sim\frac{1}{|x|^{N+2s}}$. The result is new even for homogeneous functions $f(u)=|u|^{r-2}u$, $r\in [\frac{N+\alpha}{N},2)$, and it complements the decays obtained in the linear and superlinear cases in [D'Avenia, Siciliano, Squassina (2015)] and [Cingolani, Gallo, Tanaka (2022)]. Differently from the local case $s=1$ in [Moroz, Van Schaftingen (2013)], new phenomena arise connected to a new "$s$-sublinear" threshold that we detect on the growth of $f$. To gain the result we in particular prove a Chain Rule type inequality in the fractional setting, suitable for concave powers

Regulation of metabolism in Caenorhabditis elegans longevity

The nematode Caenorhabditis elegans is a favorite model for the study of aging. A wealth of genetic and genomic studies show that metabolic regulation is a hallmark of life-span modulation. A recent study in BMC Biology identifying metabolic signatures for longevity suggests that amino-acid pools may be important in longevity

Perché le imprese ricorrono al factoring? Il caso dell'Italia.

In this paper we examine the main aspects of Italian factoring market and its evolution during last two decades. Moreover, we analyze the characteristics of firms accessing this kind of financing. In Italy factoring market size is the third in the world in absolute terms (amount of turnover), after U.K. and U.S., and the first one in relative terms (turnover to GDP ratio). This diffusion is related to the widespread use of postponed payment in commercial transaction, giving rise to a large amount of trade credit. At the end of 2002, financial factors market share was about two third. The remaining part was referred to industrial factors, that are specialized in “indirect” factoring, i.e. providing external funding to suppliers of the industrial group companies. This is an Italian market peculiarity owed to the opportunity for the debtor to prevent the trade credit to be transferred without his agreement. Firms accessing factoring show a greater financial pressure: the higher the leverage and the lower the cash flow and liquidity indicators, the higher is the probability to factor accounts receivable. The role of financial hypothesis in explaining the factoring choice is weaker for industrial factors customers, for which commercial reasons seem to be prevalent.Factoring, Fabbisogno finanziario, Credito commerciale

Editorial: Management and Treatment of Pilonidal Disease: 189 Years After Mayo

...Pilonidal Disease (PD) was first scientifically reported 189 years ago by Herbert Mayo, back in 1833, as a sinus containing hair follicles located in the sacrococcygeal region of a female patien

Extradural hemorrhagic spinal cavernous angioma in a paucisymptomatic child: A rare case with review of the current literature

Background: Cavernous angiomas, also referred to as cavernous hemangiomas or cavernomas (CMs), are vascular malformative benign neoplasms that may develop in any part of the central nervous system. Spinal CMs are uncommon (overall incidence rate of 0.04-0.05%). Pure epidural CMs account for 1-2% of all spinal CMs and 4% of all spinal epidural tumors. Diagnosis is extremely rare in the pediatric age. To the best of our knowledge, only 10 cases have been described so far. The treatment of choice is microsurgical resection. Case description: We describe here the rare case of a cervicothoracic hemorrhagic spinal epidural cavernoma in a paucisymptomatic, 8-year-old female Bangladeshi child. C7-T2 laminectomy with excision of a scarcely defined, capsulated dark red lesion was performed with good recovery. Conclusion: Spinal epidural cavernomas are rare. Childhood presentation is even rarer. The reason could be found in a greater "compliance" and to a rarer occurrence of acute bleeding in children, thus resulting in a delayed diagnosis. Surgical excision is the gold standard of treatment
