We consider a random synaptic pruning in an initially highly interconnected network. It is proved that a random network can maintain a self-sustained activity level for some parameters. For such a set of parameters a pruning is constructed so that in the resulting network each neuron/node has almost equal numbers of in- and out-connections. It is also shown that the set of parameters which admits

Previous studies have shown gender differences in preoperative status and outcome of spine surgery. This study explores whether gender differences in preoperative demographics exist in patients scheduled for lumbar disc herniation (LDH) surgery.

Tri-isopropylsilyl thio-glycosides (TIPS S-glycosides) were synthesized through base promoted SN2 substitution of glycosyl halides with TIPS-SH or by Lewis acid promoted glycosylation of TIPS-SH with glycosyl acetates or p-methoxyphenyl glycosides. Various thioglycoside derivatives were obtained in high yields by one-pot fluoride-mediated de-silylation and thiol alkylation with alkyl halides or Mi

Purpose: To study the feasibility of using transscleral visible/near-infrared spectroscopy (Vis/NIRS) to estimate the content of haemoglobin in choroidal tumour phantoms of ex vivo porcine eyes. Methods: Thirty enucleated porcine eyes were prepared with a tumour phantom made by injecting a suspension of gelatine, titanium dioxide and human blood into the suprachoroidal space. The blood concentrati

An economically sustainable process was developed for propionic acid production by fermentation of glycerol using Propionibacterium acidipropionici and potato juice, a by-product of starch processing, as a nitrogen/vitamin source. The fermentation was done as high-cell-density sequential batches with cell recycle. Propionic acid production and glycerol consumption rates were dependent on initial b

Myofibroblastoma (MFB) is a benign neoplasm arising most frequently in the adult breast, but it may occur in any other tissue with the exception of the central nervous system. Adequate treatment of this neoplasm consists of local excision. MFB shows characteristic histological features and a clear immunohistochemical profile and usually does not cause any diagnostic difficulties [1-4]. A rare vari

Heat transfer and pressure drop characteristics of Al2O3/water and MWCNT/water nanofluids flowing in a chevron-type plate heat exchanger were experimentally investigated and compared with those of water. Results showed that heat transfer seemed to be improved by using nanofluids at constant Reynolds number. However, little heat transfer enhancement was observed based on a constant flow velocity. T

Background Families with parental intellectual disabilities (ID) are likely to need support in achieving a decent family life. In order to accurately plan for such support services, society needs data regarding the occurrence of those parents and their children. The aim of this study was to investigate the 5-year incidence of children born to women with ID in a county in Sweden. Methods Women born

The kinetics for the binding of cisplatin to duplex RNAs, two fully complementary model systems and mature miR-146a, exhibits a linear dependence on cisplatin concentration and results in duplex dissociation at 38 °C.

Abstract Lymphoedema treatment outcome can be evaluated by calculating estimated limb volumes directly by water displacement (plethysmography; PG), or indirectly by circumference measurements (CM) and using the formula for a truncated cone. This study assessed the correlation between PG and circumference volume measurements to assess whether the correlation is acceptable, and if circumference meas

There are good reasons to believe that furniture designers can play an important role in the design of appropriate caring environments and thus contribute to the care that is provided. Designers are usually engaged by manufacturers that develop furniture for public procurement and a market for elderly consumers but without being able to learn from those who spend their everyday lives in these envi

We describe the design of the NanoMAX beamline to be built among the first phase beamlines of the MAX IV facility in Lund, Sweden. NanoMAX will be a hard X-ray imaging beamline providing down to 10 nm in direct spatial resolution, enabling investigations of very small heterogeneous samples exploring methods of diffraction, scattering, absorption, phase contrast and fluorescence. The beamline will

In a previous publication [ P. A. T. Olsson, J. Appl. Phys. 108, 034318 (2010) ], molecular dynamics (MD) simulations have been performed to study the resonant properties of gold nanowires. It has been documented in the aforementioned publication that the eigenfrequencies of the fundamental mode follows the continuum mechanically predicted behavior when Bernoulli–Euler beam theory is used, whereas

The time-dependent process of raindrop freezing is described in a general form, including thermodynamic effects from the accretion of cloud liquid and cloud ice. Freezing drops (FDs) larger than 80 m (and their water mass) are represented explicitly in a cloud model with spectral bin microphysics. FDs consist of interior water covered by ice initially. Possibilities of both dry (icy surface) and w

Understanding the possible pH-buffering processes is of maximum importance for risk assessment and remediation feasibility studies of heavy-metal contaminated soils. This paper presents the results about the effect of the buffering capacity of a polluted soil, rich in carbonates, on the pH and on the leaching evolution of its main contaminant (lead) when a weak acid (acetic acid) or a strong one (

BACKGROUND: A fracture in childhood is associated with low bone mineral density (BMD), but it is debated whether a fracture at growth also predicts low BMD in young adulthood. PURPOSE: To gender-specifically evaluate whether children with a fracture are at increased risk of low BMD in young adulthood. METHODS: Distal forearm BMD (g/cm(2) ) was measured with single photon absorptiometry (SPA) i

The opening of the Arctic Ocean involved multiple stages of continental rifting and intrusion of extensive dyke swarms. To trace tectonomagmatic processes of the High Arctic, we present the first U-Pb ages for alkaline dyke swarms of North Greenland. Concordia ages of 80.8 +/- 0.6 and 82.1 +/- 1.5 Ma indicate that north-south and east-west dykes are coeval. The north-south dykes reflect initial ea

Easily available, accurate glucose recordings are important when screening for and managing people with diabetes. The photometric HemoCue(®) (Ängelholm, Sweden) Glucose 201+ system, which delivers lab-comparable glucose recordings, has the drawback that its microcuvettes must be delivered and stored at 4-8°C. A newly developed system, HemoCue Glucose 201RT, has microcuvettes that can be stored at

The search for novel, atom-economic methods for the formation of C-C bonds is of crucial importance in synthetic chemistry. Especially attractive are reactions where C-C bonds are formed through C-H activation, but the coupling of unactivated, alkane-type C-sp3-H bonds remains an unsolved challenge. Here, we report iridium-mediated intramolecular coupling reactions involving up to four unactivated
