Optical nonreciprocity is of paramount importance to optical signal processing and one-way optical communication. Here, we theoretically and experimentally demonstrate nonreciprocal amplification base...
A polar conductor, where inversion symmetry is broken, may exhibit directional propagation of itinerant electrons, i.e., the rightward and leftward currents differ from each other, when time-reversal ...
In magnetoelectric materials, where the time-reversal and space-inversion symmetries are simultaneously broken, optical properties can differ between the opposite propagation directions of light. We r...
We study lasing at the high-symmetry points of the Brillouin zone in a honeycomb plasmonic lattice. We use symmetry arguments to define singlet and doublet modes at the K points of the reciprocal spac...
Realizing dynamic wavelength tunability could bring about tremendous impacts in laser technology, pressure nanosensing, and lab-on-a-chip devices. Here, we demonstrate an original strategy to operate ...
The purpose of this study is to investigate the clinical efficacy of directional DBS electrode technology and whether electrophysiology biomarkers can predict effective contact segments fo...
The purpose of this study is to provide proof-of-concept that directional stimulation and directional recording, in an intraoperative setting, is perceivable in a subject. The tests will b...
The purpose of the study is to investigate efficacy and safety boron neutron capture therapy (BNCT) administered in combination with cetuximab in the treatment of head and neck cancer that...
This study occurs during five visits that are already scheduled as part of "Biomarkers to Guide Directional DBS for Parkinson's Disease" (ClinicalTrials.gov Identifier: NCT03353688). If pa...
Directional microphone hearing aids have been shown to provide benefit for individuals with hearing loss in a number of laboratory experiments. However, few studies have investigated the r...
Work consisting of an acknowledgment of an error, issued by a publisher, editor, or author. It customarily cites the source where the error occurred, giving complete bibliographic data for retrieval. In the case of books and monographs, author, title, imprint, paging, and other helpful references will be given; in the case of journal articles, the author, title, paging, and journal reference will be shown. An erratum notice is variously cited as Errata or Corrigenda.
A parasexual process in BACTERIA; ALGAE; FUNGI; and ciliate EUKARYOTA for achieving exchange of chromosome material during fusion of two cells. In bacteria, this is a uni-directional transfer of genetic material; in protozoa it is a bi-directional exchange. In algae and fungi, it is a form of sexual reproduction, with the union of male and female gametes.
A constellation of responses that occur when an organism is exposed to excessive cold. In humans, a fall in skin temperature triggers gasping, hypertension, and hyperventilation.
A condition characterized by the recurrence of HEMOGLOBINURIA caused by intravascular HEMOLYSIS. In cases occurring upon cold exposure (paroxysmal cold hemoglobinuria), usually after infections, there is a circulating antibody which is also a cold hemolysin. In cases occurring during or after sleep (paroxysmal nocturnal hemoglobinuria), the clonal hematopoietic stem cells exhibit a global deficiency of cell membrane proteins.
A climate characterized by COLD TEMPERATURE for a majority of the time during the year.
