III-V device integration on Si using template-assisted selective epitaxy

High mobility (III-V) materials have long been anticipated to replace Si MOSFETs. But only recently [1] were scaled InAs MOSFETs reported to outperform Si devices. However, high-performing III-V devices are typically fabricated on InP substrates which are not compatible with large-scale chip manufacturing. While various III-V on Si fabrication approaches have been reported to overcome this issue,

Vertical InAs-Si gate-all-around tunnel FETs integrated on Si using selective epitaxy in nanotube templates

In this paper, we introduce ${p -channel InAs-Si tunnel field-effect transistors (TFETs) fabricated using selective epitaxy in nanotube templates. We demonstrate the versatility of this approach, which enables III-V nanowire integration on Si substrates of any crystalline orientation. Electrical characterization of diodes and of TFETs fabricated using this method is presented; the TFETs exhibit a

Vertical III-V nanowire device integration on Si(100)

We report complementary metal-oxide-semiconductor (CMOS)-compatible integration of compound semiconductors on Si substrates. InAs and GaAs nanowires are selectively grown in vertical SiO2 nanotube templates fabricated on Si substrates of varying crystallographic orientations, including nanocrystalline Si. The nanowires investigated are epitaxially grown, single-crystalline, free from threading dis

III-V semiconductor nanowires for future devices

The monolithic integration of III-V nanowires on silicon by direct epitaxial growth enables new possibilities for the design and fabrication of electronic as well as optoelectronic devices. We demonstrate a new growth technique to directly integrate III-V semiconducting nanowires on silicon using selective area epitaxy within a nanotube template. Thus we achieve small diameter nanowires, controlle

Communicating to Employees the Implementation of Patient Online Access to Their EHR. The Case of Adult Psychiatry in Southern Sweden.

In 2015 Region Skåne was the first county council in Sweden to add adult psychiatry patients to the civic service of patient online access to their EHR (electronic health records). The initial implementation of the service in somatic care had previously raised both questions and resistance amongst the healthcare professionals. It was thus considered important to inform the professionals involved a

An action-oriented method for interprofessional organization development at a hospital operating unit

The complexity of modern interdisciplinary health care practices, where different specialties work together to solve complex problems, challenges traditional approaches to organizational development and quality improvement. An example of this is surgery. This article describes and evaluates an action-oriented method to facilitate organizational development and innovation at an operating unit, cent

Method for the prevention of thromboembolic disorders

A method for the prevention of thrombotic, embolic and/or hemorrhagic disorders, such as cerebral infarction (stroke) or myocardial infarction, by administering levosimendan or its metabolite (II) or any of their pharmaceutically acceptable salts to a mammal in need of such prevention

Functional Connectivity Is Associated With Altered Brain Chemistry in Women With Endometriosis-Associated Chronic Pelvic Pain

UNLABELLED: In contrast to women with relatively asymptomatic endometriosis, women with endometriosis-associated chronic pelvic pain (CPP) exhibit nonpelvic hyperalgesia and decreased gray matter volume in key neural pain processing regions. Although these findings suggest central pain amplification in endometriosis-associated CPP, the underlying changes in brain chemistry and function associated

Prospective analysis of parametric response map-derived MRI biomarkers: : identification of early and distinct glioma response patterns not predicted by standard radiographic assessment

PURPOSE: Currently, radiologic response of brain tumors is assessed according to the Macdonald criteria 10 weeks from the start of therapy. There exists a critical need to identify nonresponding patients early in the course of their therapy for consideration of alternative treatment strategies. Our study assessed the effectiveness of the parametric response map (PRM) imaging biomarker to provide f

Neuroimaging evaluation of non-accidental head trauma with correlation to clinical outcomes : a review of 57 cases

OBJECTIVE: To review the clinical presentation and neuroimaging findings in patients with high clinical suspicion for non-accidental trauma (NAT) of the head, to investigate associations between imaging findings and long-term neurologic outcome in abused children.STUDY DESIGN: A retrospective review of 57 cases of NAT of the head from a single institution was performed. Neuroimaging studies (compu

Manually adjusted versus vendor-preset definition of metabolite boundaries impact on proton metabolite ratios

RATIONALE AND OBJECTIVES: Metabolite peak boundary definition is an important postprocessing step in proton magnetic resonance spectroscopy (1H-MRS). We compare metabolite ratios calculated using three different postprocessing strategies: software-rendered default peak boundaries, manually adjusted peak boundaries and a curve-fitting program. The first two of these methods are commercially availab

Compounds for deactivating phospholamban function on Ca-ATPase (phospholamban inhibitors)

This invention relates to determining the three-dimensional structure of the cytosolic domain of phospholamban (PLB) and its active site from NMR data of sufficiently high resolution for the three-dimensional structure determination. The invention also relates to methods for rational drug design enabling the design of phospholamban inhibitors based on using the three-dimensional structure data pro

Abnormalities on brain MR images during the course of familial haemophagocytic lymphohistocytosis in a child. A case report

PURPOSE: To describe and report the neuroradiological findings and clinical features in a patient with familial haemophagocytic lymphohistocytosis (FHL), a rare hereditary immune dysregulation in early childhood characterised by multisystem involvement, including in approximately 30% of cases also the central nervous system (CNS).MATERIAL AND METHODS: Serial brain MR examinations were carried out

Two-Phase Flow Analysis in a Cathode Duct of PEFCs

A three-dimensional calculation method has been further developed to include two-phase, multi-component gas and heat transport processes. A set of momentum, heat transport and gas species equations have been solved for the whole duct by coupled source terms and variable thermophysical properties. The effects of the electrochemical reactions on the heat generation and mass consumption/generation ha

Neural tolerance of the non-ionic dimers iodixanol and iotrolan and the non-ionic monomer iopamidol during myelography in non-anaesthetised rabbits

PURPOSE: The neural tolerance of the recently introduced dimer iodixanol (320 g I/l) was compared with that of the dimer iotrolan (300 g I/l) and of the monomer iopamidol (300 g I/l), both used in clinical myelography.MATERIAL AND METHODS: Non-anaesthetised rabbits were injected into the cisterna magna with Ringer's solution (control) or contrast media (CM) at doses of 1.0 or 0.5 ml/kg b.w. The be

Value of radiography in the management of possible fishbone ingestion

A retrospective study was performed on 42 consecutive patients to examine the value of radiography in the management of complaints of fishbone ingestion. All patients underwent an oral examination followed by radiographic examination with plain films, barium swallows, barium and water swallows, and an endoscopic examination. All radiographs were reviewed by two unbiased, experienced radiologists.

Elevation of the larynx on normal and abnormal cineradiogram

The relationship between bolus volume (2.5, 5, 10 and 20 ml) and larynx elevation during swallowing was assessed in 10 non-dysphagic and 10 dysphagic individuals without pharyngeal dysfunction. Laryngeal elevation in different types of pharyngeal dysfunction was assessed in 60 non-dysphagic and 75 dysphagic patients. All subjects were examined with liquid barium and cineradiography at 50 frames/s.

Relaxation dynamics of SF6 studied by energy resolved electron ion coincidence technique

The mass spectra from the SF6 molecule acquired by energy-resolved electron ion coincidence (EREICO) technique using (1t1g + [5t1u,1t2u]), (3eg + 1t2g), 4t1u, and 5a1g electrons after both valence and S 2p−1 6a1g core excitation reveal a strong selectivity in the dissociation from these states. From the comparison of the obtained spectra, the influence of the core-excited state in the relaxation p
