Low-frequency noise in vertical InAs nanowire FETs

This letter presents dc characteristics and low-frequency noise (LFN) measurements on single vertical InAs nanowire MOSFETs with 35-nm gate length and HfO2 high-kappa dielectric. The average normalized transconductance for three devices is 0.16 S/mm, with a subthreshold slope of 130 mV/decade. At 10 Hz, the normalized noise power S-I/I-d(2) measures 7.3 x 10(-7) Hz(-1). Moreover, the material-depe

Quarry marks in Partition B, Main Quarry at Gebel el Silsila : remarks on their meaning and function

Famous for its many New Kingdom stelai and funerary shrines, Speos of Horemheb and magnificent quarries, this paper presents a preliminary report on a lesser acknowledged feature of Gebel el Silsila: its quarry marks. Focusing here on the northern section – Partition B – of Silsila East’s Main Quarry, seventeen individual quarry faces display totally 376 quarry marks, which have been divided into

Complications and survival after surgical treatment of 214 metastatic lesions of the humerus

Background: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. Materials and methods: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intram

Superoxide dismutase inspired Fe(III)-amino acid complexes covalently grafted onto chloropropylated silica gel - Syntheses, structural characterisation and catalytic activity

In this work the syntheses, structure and SOD activity of covalently grafted Fe(III)-complexes formed with various N- or C-protected amino acid ligands (L-histidine and L-tyrosine) inspired by the active site of the Fe SOD enzyme are presented. Chloropropylated silica gel was used as support to mimic the proteomic skeleton of the enzyme. Anchored complexes having uniform amino acids as well as the

GENERAL ORAL GLUCOSE TOLERANCE TEST DURING PREGNANCY, AN OPPORTUNITY FOR IMPROVED PREGNANCY OUTCOME AND IMPROVED FUTURE HEALTH.

Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som förhöjt blodglukos (blodsocker) som uppstår eller upptäcks under graviditet och som oftast försvinner efter förlossningen. Orsaken anses vara en otillräcklig förmåga att öka insulinproduktionen i takt med det ökade behov som normalt uppträder under en graviditet till följd av hormonella förändringar. Livsstilsfaktorer såsom stillGestational diabetes mellitus (GDM) is associated with a risk of adverse pregnancy outcome and is a predictor of subsequent diabetes. The aims of this work were to describe a reliable routine to diagnose abnormal glucose tolerance during pregnancy, to investigate women’s opinions of the specialist care provided, to determine the prevalence of diabetes one year after giving birth, and to elucidate

Risk factors and prevention among patients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital

Aims and objectives. This study aimed to describe and identify risk factors associated with hospital-acquired pressure ulcers among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Background. Pressure ulcers occur most often in older and imm

Unperturbed moderator brightness in pulsed neutron sources

The unperturbed neutron brightness of a moderator can be defined from the number of neutrons leaving the surface of a moderator completely surrounded by a reflector. Without openings for beam extraction, it is the maximum brightness that can be theoretically achieved in a moderator. The unperturbed brightness of a cylindrical cold moderator filled with pure para-H-2 was calculated using MCNPX; the

Securitization of energy supply chains in China

Energy policies in China, the world’s largest energy consumer, are an important factor in shaping the 41 global energy system. While scholars agree that energy security is a major driver of China’s energy 42 policies, there is insufficient understanding of what exactly constitutes China’s energy security from the 43 policy perspective. We apply recent insights from the Global Energy Assessment, pa

PREDICTIVE AND PROGNOSTIC MARKERS IN SQUAMOUS CELL CARCINOMA OF THE HEAD AND NECK

Survival of patients with locally advanced head and neck squamous cell cancer(HNSCC)is poor, with an overall survival < 50%, despite diagnostic and therapeutic advances. The identification of prognostic and predictive markers could help optimizing treatment. From 18 patients, six tumour cell lines were established and four were xenografted to nude mice. Proliferation parameters(cell doubling time,

Search for supersymmetric particles in events with lepton pairs and large missing transverse momentum in root s=7 TeV proton-proton collisions with the ATLAS experiment

Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical-sign or opposite-sign electric charges are described. In a data sample corresponding to an integr

Mechanism Insights of Ethane C-H Bond Activations by Bare [Fe-III=O](+): Explicit Electronic Structure Analysis

Alkane C-H bond activation by various catalysts and enzymes has attracted considerable attention recently, but many issues are still unanswered. The conversion of ethane to ethanol and ethene by bare [Fe-III=O](+) has been explored using density functional theory and coupled-cluster method comprehensively. Two possible reaction mechanisms are available for the entire reaction, the direct H-abstrac

Striving for scientific stringency: a re-analysis of a randomised controlled trial considering first-time mothers' obstetric outcomes in relation to birth position

Background: The aim of this study was to compare maternal labour and birth outcomes between women who gave birth on a birth seat or in any other position for vaginal birth and further, to study the relationship between synthetic oxytocin augmentation and maternal blood loss, in a stratified sample. Methods: A re-analysis of a randomized controlled trial in Sweden. An on-treatment analysis was used

Gating attosecond pulses in a noncollinear geometry

The efficient generation of isolated attosecond pulses (IAPs), giving access to ultrafast electron dynamics in various systems, is a key challenge in attosecond science. IAPs can be produced by confining the extreme ultraviolet emission generated by an intense laser pulse to a single field half-cycle or, as shown recently, by employing angular streaking methods. Here, we experimentally demonstrate

Multimodal Retrieval of Autobiographical Memories: Sensory Information Contributes Differently to the Recollection of Events

Previous studies on autobiographical memory have focused on unimodal retrieval cues (i.e., cues pertaining to one modality). However, from an ecological perspective multimodal cues (i.e., cues pertaining to several modalities) are highly important to investigate. In the present study we investigated age distributions and experiential ratings of autobiographical memories retrieved with unimodal and
