Abstract Electronic structures and magnetotransport properties of topological Dirac semimetal (TDSM) nanoribbons are studied by adopting the tight-binding lattice model Landauer–Büttiker formula based on non-equilibrium Green’s function. For concreteness, TDSM material Cd 3 As 2 grown along experimentally accessible [110] crystallographic direction is taken as an example. We found that electron...

In this paper, we study the left orthogonal class of max-flat modules which are homological objects related to s-pure exact sequences and module homomorphisms. Namely, a right $A$ is called MF-projective if ${Ext}^{1}_{R}(A,B)=0$ for any $R$-module $B$, strongly ${Ext}^{i}_{R}(A,B)=0$ all $R$-modules $B$ $i\geq 1$. Firstly, give some properties $MF$-projective SMF-projective modules. Then intro...

The spontaneous recessive mutant mouse stargazer (stg) begins to show ataxia around postnatal day 14 and display a severe impairment in the acquisition of classical eyeblink conditioning in adulthood. These abnormalities have been attributed to the specific reduction in brain-derived neurotrophic factor (BDNF) and the subsequent defect in TrkB receptor signaling in cerebellar granule cells (GCs...

We have analyzed high-resolution, adaptive optics (AO) HK observations of the Arches cluster obtained with NAOS/CONICA. With a spatial resolution of 84 mas, the cluster center is uniquely resolved. From these data the present-day mass function (MF) of Arches is derived down to ∼ 4M⊙. The integrated MF as well as the core and 2 annulus MFs are consistent with a turn-over at 6−7M⊙. This turn-over...

background: diagnosis of the early phase of mycosis fungoides (mf) is sometimes difficult. loss of cd7 expression is considered a distinguishing characteristic of mf. the aim of this study was to determine the range of cd7 expression in mf and compare the results with benign inflammatory dermatosis and equivocal cases of possible mf.   methods: during a period of 30 months, we examined 15 patie...

OBJECTIVE To determine sensitivity and specificity of clinical tools viz. nerve palpation (NP), monofilament (MF), and voluntary muscle testing (VMT), for assessing peripheral nerve function impairment (NFI) in leprosy, using nerve conduction studies (NCS) as gold standard. STUDY POPULATION AND METHODS 357 untreated multibacillary (MB) leprosy patients were assessed using above tests. The ner...
