The Poiseuille flow has been widely analyzed from analytical and experimental point of view with different approaches. Although the Lattice Boltzmann method (LBM) has proven to be a suitable tool for mimicking the fluid flow behavior not only for complex but also for simple geometries such as lid driven cavity and channel flow, the required computational size or characteristic length to obtain an

Background: Long-distance migration has evolved multiple times in different animal taxa. For insect migrants, the complete annual migration cycle covering several thousand kilometres, may be performed by several generations, each migrating part of the distance and reproducing. Different life-cycle stages and preferred orientation may thus, be found along the migration route. For migrating red admi

Emergent order at mesoscopic length scales in condensed matter can provide fundamental insight into the underlying competing interactions and their relationship with the order parameter. Using spectromicroscopy, we show that mesoscopic stripe order near the metal-insulator transition (MIT) of strained VO2 represents periodic modulations in both crystal symmetry and V - V dimerization. Above the MI

We present measurements of one-dimensional superconductor-semiconductor Coulomb islands, fabricated by gate confinement of a two-dimensional InAs heterostructure with an epitaxial Al layer. When tuned via electrostatic side gates to regimes without subgap states, Coulomb blockade reveals Cooper-pair mediated transport. When subgap states are present, Coulomb peak positions and heights oscillate in

The glymphatic system is a brain-wide clearance pathway; its impairment contributes to the accumulation of amyloid-β. Influx of cerebrospinal fluid (CSF) depends upon the expression and perivascular localization of the astroglial water channel aquaporin-4 (AQP4). Prompted by a recent failure to find an effect of Aqp4 knock-out (KO) on CSF and interstitial fluid (ISF) tracer transport, five groups

Erythroid cell commitment and differentiation proceed through activation of a lineage-restricted transcriptional network orchestrated by a group of cell fate determining and maturing factors. We previously set out to define the minimal set of factors necessary for instructing red blood cell development using direct lineage reprogramming of fibroblasts into induced erythroid progenitors/precursors

Insect migrations are spectacular natural events and resemble a remarkable relocation of biomass between two locations in space. Unlike the well-known migrations of daytime flying butterflies, such as the painted lady (Vanessa cardui) or the monarch butterfly (Danaus plexippus), much less widely known are the migrations of nocturnal moths. These migrations - typically involving billions of moths f

Bidraget analyserar Kinas folkrättsliga strategi med avseende på att använda militärt våld i cyberrymden. Kinas statspraxis och opinio juris (d v s dess folkrättsliga övertygelse) undersöks och kinesiska folkrättsvetenskapliga yttranden oc ståndpunkter granskas.

Bidraget sammanställer de konferensformat som etablerats inom ramen för internationella nedrustnings- och rustningskontrollfördrag, förklarar dessas specifika procedurbestämmelser och analyserar dessas ändamålsenlighet och effektivitet i ljuset av respektive traktats syfte och mot bakgrund av de erfarenheter som samlats vid konferensernas genomförande.

Animal bedding, a mixture of straw and manure, could be used as a feedstock for bioenergy production, but its heterogeneity poses new challenges in its use in biorefineries. We have investigated the origin of this heterogeneity and quantified it, and discuss its impact on bioenergy production. Samples were collected from the bedding at different points and depths and analysed by first separating t

Dynamic glucose-enhanced (DGE) imaging uses chemical exchange saturation transfer magnetic resonance imaging to retrieve information about the microcirculation using infusion of a natural sugar (D-glucose). However, this new approach is not yet well understood with respect to the dynamic tissue response. DGE time curves for arteries, normal brain tissue, and cerebrospinal fluid (CSF) were analyzed

Synucleinopathies, including Parkinson’s disease (PD), dementia with Lewy bodies(DLB) and multiple system atrophy (MSA), are a group of neurodegenerative disorders characterized by the abnormal accumulation of insoluble alpha-synuclein (α-syn) aggregates in the brain. The detection of α syn pathology has relied vastly on the use of several antibodies, which were mostly generated against different

Since the 1980s, China’s central government has created various model and incentive schemes aimed at systematically and concurrently promoting innovative approaches for protecting the urban ecological environment. In this context, programmes such as the ‘model city for protecting the environment’, ‘garden city’, ‘eco-city’, or ‘low-carbon city’ have become an integral part of China’s system for ur
