Hungary: National Deposit Insurance Fund
At the height of the Global Financial Crisis (GFC), Hungary announced changes to its deposit-insurance system on October 8, 2008. The government said that it would increase the deposit-insurance cap from HUF 6 million to HUF 13 million (about USD 31,000 to about USD 68,000), the equivalent of roughly EUR 50,000 (about USD 68,000), in line with a European Union (EU) recommendation. Hungary’s finance minister also announced that the state would temporarily provide an unlimited deposit guarantee, following the actions of several European countries. The unlimited guarantee was political, meaning it was not implemented through official legislation. It was effective immediately, while the increased coverage came into effect on October 15, 2008. The National Deposit Insurance Fund (NDIF), Hungary’s deposit insurer, administered Hungary’s crisis-time deposit guarantee as an extension of its statutory authority; membership was compulsory for most deposit-taking institutions. The following year, in response to an EU directive, Hungary raised the deposit-insurance cap to the Hungarian forint (HUF) equivalent of EUR 100,000, among other measures. In February 2010, the NDIF and government made good on their respective guarantees when one institution failed. Another failure occurred in January 2011, for which each depositor received the HUF equivalent of EUR 100,000
Interactions and magnetotransport through spin-valley coupled Landau levels in monolayer MoS
The strong spin-orbit coupling and the broken inversion symmetry in monolayer
transition metal dichalcogenides (TMDs) results in spin-valley coupled band
structures. Such a band structure leads to novel applications in the fields of
electronics and optoelectronics. Density functional theory calculations as well
as optical experiments have focused on spin-valley coupling in the valence
band. Here we present magnetotransport experiments on high-quality n-type
monolayer molybdenum disulphide (MoS) samples, displaying highly resolved
Shubnikov-de Haas oscillations at magnetic fields as low as . We find the
effective mass , about twice as large as theoretically predicted and
almost independent of magnetic field and carrier density. We further detect the
occupation of the second spin-orbit split band at an energy of about ,
i.e. about a factor larger than predicted. In addition, we demonstrate an
intricate Landau level spectrum arising from a complex interplay between a
density-dependent Zeeman splitting and spin and valley-split Landau levels.
These observations, enabled by the high electronic quality of our samples,
testify to the importance of interaction effects in the conduction band of
monolayer MoS.Comment: Phys.Rev.Lett. (2018
Case report and literature review: Orally ingested toothpick perforating the lower rectum
IntroductionMost foreign bodies (FBs) can spontaneously pass through the gastrointestinal tract. Sharp FBs are believed to be able to puncture any part of the gastrointestinal tract, causing perforation and potentially secondary damage to adjacent organs.Case descriptionA 44-year-old man complained of having persistent dull pain in the perianal region. He was diagnosed with a toothpick impacted into the wall of the lower rectum after accepting a digital rectal examination of the lower rectum and a pelvic computed tomography (CT). The surgeon extracted the FB using vascular forceps guided by the operator’s index finger. The patient was discharged after intravenous ceftriaxone was given for 6 days. A follow-up pelvic CT performed 2 weeks after surgery revealed that the perirectal fat and muscles had already normalized.ConclusionA systematic review of relevant literature from the past decade was performed to summarize the imaging features of an orally ingested toothpick perforating the gastrointestinal tract. The location of abdominal pain is an important clue for the diagnosis of toothpick perforation, and a CT examination is recommended as the first option for the detection of an ingested toothpick. Determining the location of the toothpick perforation and assessing the severity of local inflammation are important bases for the selection of treatment
Electronic g-factor and Magneto-transport in InSb Quantum Wells
High mobility InSb quantum wells with tunable carrier densities are
investigated by transport experiments in magnetic fields tilted with respect to
the sample normal. We employ the coincidence method and the temperature
dependence of the Shubnikov-de Haas oscillations and find a value for the
effective g-factor of =354 and a value for the
effective mass of , where is the electron mass in
vacuum. Our measurements are performed in a magnetic field and a density range
where the enhancement mechanism of the effective g-factor can be neglected.
Accordingly, the obtained effective g-factor and the effective mass can be
quantitatively explained in a single particle picture. Additionally, we explore
the magneto-transport up to magnetic fields of 35 T and do not find features
related to the fractional quantum Hall effect.Comment: 18 Pages, 5 Figure
