Through intercalation of metals and gases the Dirac cone of graphene on Ir(111) can be shifted with respect to the Fermi level without becoming destroyed by strong hybridization. Here, we use x-ray photoelectron spectroscopy to measure the C 1s core level shift (CLS) of graphene in contact with a number of structurally well-defined intercalation layers (O, H, Eu, and Cs). By analysis of our own an
The Middle Ordovician (Dapingian–middle Darriwilian) “orthoceratite limestone” is documented in its traditional type area at Kinnekulle in the province of Västergötland in southern Sweden. Detailed field studies combined with systematic qualitative and quantitative analyses of carbonate microfacies at high stratigraphic resolution show that this suite of cool-water carbonate rocks is more variable
In 1920, the working day in Swedish manufacturing and services was cut from 10 to 8 hours without wages being cut correspondingly. Since workers demanded and got the same daily wage working 8 hours as they had with 10, real hourly wages increased dramatically; they were about 50% higher in 1921–1922 than they had been in 1919. This is the largest wage push in Swedish history, and this paper studie
We develop a method for patterning a buried two-dimensional electron gas (2DEG) in silicon using low kinetic energy electron stimulated desorption (LEESD) of a monohydride resist mask. A buried 2DEG forms as a result of placing a dense and narrow profile of phosphorus dopants beneath the silicon surface; a so-called δ -layer. Such 2D dopant profiles have previously been studied theoretically, and
Most studies that validate GFR equations present accuracy results stratified by measured GFR (mGFR; diagnostic correctness) or by estimated GFR (eGFR; diagnostic predictiveness) only, without a clear distinction in interpretation. The accuracy of a GFR equation is normally reported in percent (e.g. P30), but is often misinterpreted when stratified by eGFR. The aim of the study was to develop new a
This is an extensive review of the only book out there on the diplomatic career of Mohammad Javad Zarif, Iran's foreign minister in the Rouhani administration and top negotiator during the nuclear talks between Iran and the world powers. The book itself is available only in Persian.
Nanowire array ensembles contacted in a vertical geometry are extensively studied and considered strong candidates for next generations of industrial scale optoelectronics. Key challenges in this development deal with optimization of the doping profile of the nanowires and the interface between nanowires and transparent top contact. Here we report on photodetection characteristics associated with
Irradiating a flame via microwave radiation is a plasma-assisted combustion (PAC) technology that can be used to modify the combustion chemical kinetics in order to improve flame stability and to delay lean blow-out. One practical implication is that combustion engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. Furthermore,
This study examines the causal effects of birth weight on two health-related outcomes: inpatient hospitalizations and sickness absences, distinguishing between different diagnoses. Our analysis exploits differences within siblings and within twin pairs, using full population Swedish register data on cohorts born between 1973 and 1995, observed through childhood and in adulthood. In childhood, ther
We present a NASA-DLR SOFIA-Echelon Cross Echelle Spectrograph (EXES) and NASA Infrared Telescope Facility-Texas Echelon Cross Echelle Spectrograph (TEXES) mid-IR R ≃ 50,000 spectral study of forbidden Fe II transitions in the early-type M supergiants, Betelgeuse (α Ori: M2 Iab) and Antares (α Sco: M1 Iab + B3 V). With EXES, we spectrally resolve the ground term [Fe II] 25.99 μm ( a 6DJ= 7/2-9/2:
We report a new paleomagnetic pole for the Black Range Dolerite Suite of dykes, Pilbara craton, Western Australia. We replicate previous paleomagnetic results from the Black Range Dyke itself, but find that its magnetic remanence direction lies at the margin of a distribution of nine dyke mean directions. We also report two new minimum ID-TIMS 207Pb/206Pb baddeleyite ages from the swarm, one from
Background. The Nordic Mobility Related Outcome Evaluation of Assistive Device Intervention (NOMO 1.0) instrument evaluates the effectiveness of mobility devices in assessing mobility-related participation, captured by three scales (Need for Assistance, Frequency, and Ease/Difficulty) and one index (Participation Repertoire). Purpose. This study aimed to investigate a range of psychometric propert
We present a vertical nanowire InAs/GaAsSb/GaSb TFET with a highly scaled InAs diameter (20 nm). The device exhibits a minimum subthreshold swing of 48 mV/dec. for Vds = 0.1-0.5 V and achieves an Ion = 10.6 μA/μm for Ioff = 1 nA/μm at Vds = 0.3 V. The lowest subthreshold swing achieved is 44 mV/dec. at Vds= 0.05 V. Furthermore, a benchmarking is performed against state-of-the-art TFETs and MOSFETs
We demonstrate InGaAs tri-gate MOSFETs with an on-current of ION = 650 μA/μm at VDD = 0.5 V and IOFF = 100 nA/μm, enabled by an inverse subthreshold slope of SS = 66 mV/decade and transconductance of gm = 3 mS/μm, a Q-factor of 45. This is the highest reported Ion for both Si-based and III-V MOSFETs. These results continue to push III-V MOSFET experimental performance towards its theoretical limit
Hospitalised patients are faced with a brute reorientation of their normal spatial needs andpreferences and forced to adjust spatially to a new environment. Patients start to re-arrangetheir own situation according to personal needs and the site-specific circumstances. It is are-arrangement that includes furniture, private objects and spatial positioning, but also theadjustment to the presence and
The pathophysiology of diabetes is complex and recent research put focus on the pancreatic islets of Langerhans and the insulin-secreting beta cells as central in the development of the disease. MicroRNAs (miRNAs), the small non-coding RNAs regulating post-transcriptional gene expression, are significant regulators of beta cell function. One of the most abundant miRNAs in the islets is miR-375. Th
We show that for several pattern graphs on four vertices (e.g., C4), their induced copies in host graphs with n vertices and no clique on k + 1 vertices can be deterministically detected in time Õ (nωkμ + n2k2), where Õ (f) stands for O(f(log f)c) for some constant c, and μ ≈ 0. 46530. The aforementioned pattern graphs have a pair of non-adjacent vertices whose neighborhoods are equal. By consider
