First-principles investigation of half-metallic ferromagnetism of Fe$_2$YSn (Y = Mn, Ti and V) Heusler alloys [PDF]
Condens. Matter Phys., 2021, vol. 24, No. 2, 23703, 2021 In this paper, we use the first-principles calculations based on the density functional theory to investigate structural, electronic and magnetic properties of Fe$_{2}$YSn with (Y = Mn, Ti and V). The generalized gradient approximation (GGA) method is used for calculations.

Acta Pediátrica Portuguesa, 2008 Introdução: Acutis laxa é uma doença rara do tecido conjuntivo provocada por alterações da elastina. Caracteriza-se por pele sem elasticidade, flácida, mole e enrugada, dando aos doentes um aspecto envelhecido; o envolvimento sistémico é variável. Existem formas hereditárias e adquiridas.

Metastability in a Stochastic System of Spiking Neurons with Leakage [PDF]
, 2022 We consider a finite system of interacting point processes with memory of variable length modeling a finite but large network of spiking neurons with two different leakage mechanisms. Associated to each neuron there are two point processes, describing its successive spiking and leakage times. For each neuron, the rate of the spiking point process is an

A non-depolarizing CuTi neutron supermirror guide for PERC [PDF]
, 2021 Neutron guides are used to transport slow neutrons from sources to experiments. Conventional neutron supermirror guides use alternating thin layers based on nickel and titanium. Due to the magnetic properties of nickel, their neutron reflection properties are spin-dependent, in particular when exposed to high magnetic fields.

Indian Journal of Paediatric Dermatology, 2016 Marshall's syndrome is a form of acquired cutis laxa without systemic involvement. It is characterized by acute onset of multiple erythematous papule and plaques that resolve with postinflammatory elastolysis and cutis laxa.

A novel hotspot of gelsolin instability and aggregation propensity triggers a new mechanism of amyloidosis [PDF]
arXiv, 2021 The multidomain protein gelsolin (GSN) is composed of six homologous modules, sequentially named G1 to G6. Single point substitutions in this protein are responsible for AGel amyloidosis, a hereditary disease characterized by progressive corneal lattice dystrophy, cutis laxa, and polyneuropathy. Several different amyloidogenic variants of GSN have been

A Case of Congenital Cutis Laxa (Generalized Elastolysis)
Canadian Respiratory Journal, 2005 Cutis laxa (generalized elastolysis) is characterized by sagging folds of loose skin on the face and trunk. Although grouped with hyperelastic skin conditions such as Ehlers-Danlos syndrome, cutis laxa shows an almost total lack of skin elasticity ...

Putting the Object Back into Video Object Segmentation [PDF]
arXiv, 2023 We present Cutie, a video object segmentation (VOS) network with object-level memory reading, which puts the object representation from memory back into the video object segmentation result. Recent works on VOS employ bottom-up pixel-level memory reading which struggles due to matching noise, especially in the presence of distractors, resulting in ...

Theoretical study of phase stability, electronic and magnetic properties of Rh$_2$CrGe$_{1-x}$Al$_x$ ($x = 0$, $0.25$, $0.50$, $0.75$ and $1$) Heusler alloys by FP-LAPW method [PDF]
Condens. Matter Phys., 2020, vol. 23, No. 1, 13701, 2020 First-principle calculations were performed within the framework of the density functional theory (DFT) using FP-LAPW method as implemented in WIEN2k code to determine the structural stability, electronic and magnetic properties of Rh$_2$CrGe$_{1-x}$Al$_x $($x = 0$, $0.25$, $0.50$, $0.75$ and $1$). The results showed that for Rh$_2$CrAl and Rh$_2$CrGe,
