Area-selective Electron-beam induced deposition of Amorphous-BNx on graphene

Thin, stable and inert dielectric spacers are essential for manufacturing electronic devices based on 2D materials. However, direct synthesis on top of 2D materials is difficult due to their inert nature. In this work, we studied how an electron beam induces fragmentation of borazine and enables spatially confined synthesis of amorphous-BNx on graphene at room temperature. Using a combination of X

Canadian academy of geriatric psychiatry survey of brief cognitive screening instruments

BACKGROUND: The use of brief cognitive screening instruments is essential in the assessment of dementia. The purpose of this study is to determine the frequency of use and perceived characteristics of cognitive screening instruments among Canadian psychogeriatric clinicians.METHODS: Members of the Canadian Academy of Geriatric Psychiatry (CAGP) and attendees to the 2010 Annual Scientific Meeting w

Design of robust 2,2′-bipyridine ligand linkers for the stable immobilization of molecular catalysts on silicon(111) surfaces

The attachment of the 2,2′-bipyridine (bpy) moieties to the surface of planar silicon(111) (photo)electrodes was investigated usingab initiosimulations performed on a new cluster model for methyl-terminated silicon. Density functional theory (B3LYP) with implicit solvation techniques indicated that adventitious chlorine atoms, when present in the organic linker backbone, led to instability at very

Insulin regulates fusion of GLUT4 vesicles independent of Exo70-mediated tethering

Insulin regulates cellular glucose uptake by changing the amount of glucose transporter-4 (GLUT4) in the plasma membrane through stimulation of GLUT4 exocytosis. However, how the particular trafficking, tethering, and fusion steps are regulated by insulin is still debated. In a 3T3-L1 adipocyte cell line, the Exocyst complex and its Exo70 subunit were shown to critically affect GLUT4 exocytosis. H

Digitally Down to the Countryside : Fintech and Rural Development in China

Digital finance has changed the landscape of financial service provision worldwide. China in particular, with a booming fintech sector and large numbers of users, is at the forefront of the expansion of digital financial services. As such, the country has become an important case for better understanding how fintech operates and what its expansion entails for socioeconomic development. This paper

Who Is Muhammad Reza Fallahzadeh?

Iran’s newly appointed Deputy Commander-in-Chief of the Quds Force, Muhammad Reza Fallahzadeh, is not only an experienced military man but also a politician with diplomatic experience. He is a vital asset for the Islamic Revolutionary Guard Corps, which wants to see its own man elected president in the June elections.

Infective Endocarditis Due to Corynebacterium Species : Clinical Features and Antibiotic Resistance

Background: Corynebacterium species are often dismissed as contaminants in blood cultures, but they can also cause infective endocarditis (IE), which is a severe condition. Antibiotic resistance of corynebacteria is increasing making treatment challenging. Reports on IE caused by Corynebacterium species are scarce and more knowledge is needed. Methods: Cases of IE caused by Corynebacterium species

Palaeoproterozoic reworking of early Archaean lithospheric blocks : Rocks and zircon records from charnockitoids in Volgo-Uralia

The Volgo-Uralia segment, which constitutes one fourth of the East European Craton, is covered by sedimentary deposits. From geophysical studies and examination of thousands of drillcores, Volgo-Uralia has been recognised as a vast high-grade terrain with a complex crustal history extending from the Palaeoarchaean to the Palaeoproterozoic. Our recent studies are focused on the search for the oldes

Shifts in Gene Expression Variability in the blood-stage of Plasmodium relictum

Avian malaria is a common and widespread disease of birds caused by a diverse group of pathogens of the genera Plasmodium. We investigated the transcriptomal profiles of one of the most common species, Plasmodium relictum, lineage SGS1, at multiple timepoints during the blood stages of the infection under experimental settings. The parasite showed well separated overall transcriptome profiles betw

Exosome-Functionalized Ceramic Bone Substitute Promotes Critical-Sized Bone Defect Repair in Rats

Ceramic biomaterials are promising alternatives to bone autografts. However, limited bioactivity affects their performance. Therefore, bioactive molecules and cells are often added to enhance their performance. Exosomes have emerged as cell-secreted vesicles, delivering proteins, lipids, and nucleic acids in a paracrine/endocrine fashion. We studied two complementary aspects required for exosome a

Annual to decadal temperature adaptation of the soil bacterial community after translocation across an elevation gradient in the Andes

The response of soil microbial activity to climate warming has been predicted to have a large destabilising effect on the carbon cycle. However, the nature of this feedback remains poorly understood, especially in tropical ecosystems and across annual to decadal timescales. We studied the response of bacterial community growth to 2 and 11 years of altered temperature regimes, by translocating soil

It’s About Time: Time-Dependent Tissue Damage in the Adult Porcine Retina After Enucleation

The ex vivo large animal retina is extensively used in research ranging from discovery of disease mechanisms to future treatment paradigms. Due to limited standardization when harvesting the tissue, the time after enucleation is often ex- tended for several hours, a factor that so far has not yet been fully characterized. The purpose of this study was to investi- gate the relationship between time

Fracture Energy Measurement of Prismatic Plane and Σ2 Boundary in Cemented Carbide

The grain boundary network of WC in WC-Co is important, as cracks often travel intergranularly. This motivates the present work, where we experimentally measure the fracture energy of Σ2 twist grain boundaries between WC crystals using a double cantilever beam opened with a wedge under displacement control in a WC-10wt%Co sample. The fracture energy of this boundary type was compared with cleaving
