Proper morphogenesis of neuronal dendritic spines is essential for the formation of functional synaptic networks. However, it is not known how spines are initiated. Here, we identify the inverse-BAR (I-BAR) protein MIM/MTSS1 as a nucleator of dendritic spines. MIM accumulated to future spine initiation sites in a PIP2-dependent manner and deformed the plasma membrane outward into a proto-protru...

Hydrophobic zeolitic imidazolate frameworks (ZIFs) with the chabazite (CHA) topology are synthesized by incorporating two distinct imidazolate links. Zn(2-mIm)0.86 (bbIm)1.14 (ZIF-300), Zn(2-mIm)0.94 (cbIm)1.06 (ZIF-301), and Zn(2-mIm)0.67 (mbIm)1.33 (ZIF-302), where 2-mIm = 2-methylimidazolate, bbIm = 5(6)-bromobenzimidazolate, cbIm = 5(6)-chlorobenzimidazolate, and mbIm = 5(6)-methylbenzimida...

Message in Message (MIM) is an exciting development at the physical layer of IEEE 802.11. Two transmissions that otherwise conflict with each other, may be made concurrent with MIM. However, the benefits from MIM are not immediate. Higher layer protocols need to be explicitly designed to enable its inherent concurrency. This paper investigates the opportunities and challenges with MIM, and demo...

MIM [missing in metastasis; also called MTSS1 (metastasis suppressor 1)] is an intracellular protein that binds to actin and cortactin and has an intrinsic capacity to sense and facilitate the formation of protruded membranous curvatures implicated in cellular polarization, mobilization and endocytosis. The N-terminal 250 amino acids of MIM undergo homodimerization and form a structural module ...

We review some of the recent advances in the simulation of plasmonic devices, drawing examples from our own work in metal-insulator-metal (MIM) plasmonic waveguide components and networks. We introduce the mode-matching technique for modeling of MIM waveguide devices. We derive the complete set of orthogonal modes that the MIM waveguide supports and use it to apply the mode-matching technique t...

هدف علم پلاسمونیک، مجتمع کردن مدارات نوری است، در این میان، مواد متداول مورد استفاده در افزاره های پلاسمونی به دلیل تلفات بالا، نیل به هدف علم پلاسمونیک را با مشکل همراه کرده اند. چندی پیش ثابت شد که گرافین امکان میزبانی پلاسمون های سطحی را دارد، البته با دو ویژگی منحصربه فرد نسبت به بقیه مواد: تلفات ناچیز و تنظیم پذیری پلاسمون ها. مقالات زیادی در این حوزه به چاپ رسیده اند، اما بیشتر آن ها به م...

Microdeletions/duplications in the 22q11 region cause a variety of disorders, including DiGeorge syndrome (DGS; MIM 188400), Velocardiofacial syndrome (VCFS; MIM 192430) and Cat Eye syndrome (CES; MIM 115470). DGS and VCFS have a large clinical overlap and are both caused by deletions of a specific 1-3 Mb region on chromosome 22q11. The overall birth prevalence of 22q11 deletions appears to be ...

G enetic conditions affecting hair structure or the hair growth cycle may be isolated or they may occur as part of complex syndromes with associated abnormalities of other ectodermal appendages. Defective hair structure caused by mutations in key hair structural proteins can result in severe alopecia. The best characterised conditions at the molecular level in this category are monilethrix (MIM...

The two achiral ligands tris(1-methyl-1H-imidazol-2-yl)methanol ((mim)3COH) and bis(1-methyl-1H-imidazol-2-yl)(3-methylpyridin-2-yl)methanol ((mim)2(mpy)COH) form on reaction with Fe(BF4)2∙6H2O, the octahedral low-spin complexes [Fe((mim)3COH)2](BF4)2∙MeCN (1) [Fe((mim)2(mpy)COH)2](BF4)2∙0.5MeCN (2). Both immediately rearrange to chiral [Fe4O4]-cubane clusters [Fe4(mim)3CO)4](BF4)4 (3) [Fe4(mim...
