The data were originally collected for the paper "Olfactory Response as a Marker for Alzheimer’s Disease: Evidence from Perception and Frontal **Oscillation** Coherence Deficit" in Ziaeian Hospital, Tehran, Iran. The study was conducted on mild AD and normal participants.
This data includes EEG from 4 channels (Fp1-Fz-Cz-Pz) with A1 earlobe as reference. The sampling **frequency** is 200 Hz. It contains EEG segments during olfaction of two odors (Lemon and Rosewater). Each segment contains 1 second before and 2 seconds after the stimulus onset. Segments corresponding to Lemon odor are indicated by 0 and Rosewater segments are denoted by 1 in a vector inside the dataset. In addition, noisy epoch numbers are included in the dataset. The order of the channels in the dataset is as follows: Fp1 - Fz - Cz - Pz.
The data is preprocessed and eye-blink artifact was removed using FastICA algorithm.
Data on Iran-SIT score as well as participants' MMSE scores can be found in .xlsx file.

The subject of this article is analysis of transverse vibrations of beams which geometric and material properties vary periodically along the longitudinal axis. The aim is to present averaged models that take into account the shear deformation and geometric non-linearity, and to analysand transverse vibrations of such beams in moderately large deflection range. As the theoretical foundations, we use Timoshenko beam theory with von Kármán-type non-linearity. This results in obtaining new differential equations with constant coefficients, some of which explicitly depend on the beam inhomogeneity period size. Then, a reasonably simplified model is proposed to describe the vibrations of the considered beams in the low **frequency** range. The differential equations are transformed into a system of algebraic equations according to the Galerkin method. The response of the beam to transverse harmonic load is investigated by means of a pseudo arc-length continuation scheme. Non-linear coupling between vibration modes and the possibility of superharmonic resonance occurrence are taken into account. As an example of application, few special cases of beam geometry and boundary conditions are examined and compared....Non-Linear **Oscillations** ...

Abstract
We describe the new version (v2.08k) of the code HFODD which solves the nuclear Skyrme–Hartree–Fock or Skyrme–Hartree–Fock–Bogolyubov problem by using the Cartesian deformed harmonic-**oscillator** basis. Similarly as in the previous version (v2.08i), all symmetries can be broken, which allows for calculations with angular **frequency** and angular momentum tilted with respect to the mass distribution. In the new version, three minor errors have been corrected.

We have used a newly developed quasi optical free-space time-resolved millimeter wave conductivity (TR-mmWC) system operated in the D-band (107.35 GHz to 165 GHz) with 0.5GHz resolution to acquire surface reflected probe beam voltages from high resistivity (105 Ohm-cm) 434 µm thick semi-insulating n-type gallium nitride (GaN) wafer with thickness 5 µm on sapphire. The source for millimeter waves is the backward wave **oscillator** (BWO) with a spot diameter ~3mm, and GaN sample is of commercial grade, and is rotated at an angle of 65.40 from the probe beam direction. Probe beam photon energies are in the range 0.4 to 0.7 meV. GaN refractive index for 532 nm laser pulse is 2.33 with large penetration depth compared to its thickness. Zero-bias Schottky diode (ZBD) with a responsivity ~ 3.6V/mW is used for signal detection. Stimulus of GaN surface is provided using a 532 nm DPSS laser with pulse-width 0.69 ns repeated every millisecond. The idea of performing this experiment was to note changes in photo-emission induced reflection voltages (dc) off of GaN surface as function of laser intensity, and whether the differences in illuminated and dark state reflected voltages bear any relationship with the laser fluence. GaN has a bandgap ~3.4 eV we use the 532nm pulse with energy hence no radio-**frequency** signal due to excess charge carrier kinetics is observed (no transients seen either in reflection or transmission mode) however, changes in d.c. voltages are exhibited when GaN surface is illuminated with laser pulse in the intensity range 10.1µJ/cm2 to 5.3nJ/cm2 . The differences between the probe reflection voltages while laser is ON (illuminated by a spot diameter ~10mm) and OFF (dark) when plotted as function of laser intensity, a rapid change from slightly negative to a steep positive transition occur when the laser intensity is around 0.65µJ cm-2. Four sets of data are uploaded for interested users. The laser pump intensity in micro-Joules per sq. cm appears in the filename itself for each ASCII delimited numeric data file. Probe beam **frequency** is swept automatically using LABVIEW and sampling period is 500ms. The column 1 of each file is probe beam **frequency**, column2 is the reflected voltage (average of 30 sample) from ZBD, an average of 30 samples collected for each probe **frequency** bin. Third column is the standard deviation of the laser ON voltage sample set. Fourth column is same as column 2 but when laser is switched off (dark) and fifth column is same as third column except for the reflected probe beam voltage standard deviation under dark condition. ...

Hybrid organic-inorganic perovskite (HOIP) exhibit low cost, versatility in fabrication methods and possess good application potential because of high power conversion efficiency. Methylammonium lead Iodide (MAPbI3) with quartz substrate thin film sample (glass encapsulated) was obtained from NC State University have been used to obtain millimeter wave (mmw) transient response at probe **frequencies** of 140 and 150 GHz from CIDO and BWO sources respectively. The HOIP film was produced at NC State University on May 02, 2017. In our time-resolved TR-mmWC apparatus, the glass-covered sample was excited by a 1KHz triggered 532 nm laser beam with a width of 0.7 ns with maximum fluence 10 microJoules per sq. cm and a spot size of 10mm. Transient datasets were recorded using a 6 GHz input bandwidth digitizer after amplifying Schottky detector registered radiofrequency (RF) signal due to differential absorption of the passing millimeter wave from source (normal to sample) at 140 and 150 GHz through sample. Signal averaging was done 4096 times and data were collected on 4 different dates spanning 2, 6, and 8 months and 1 year from date of manufacture. A general trend of increase in radiative and trap-assisted recombination lifetimes of charge carriers was noted, and a decrease in amplitudes were also noted after fitting data by double exponential. The fits are obtained by adding a second excitation to account for double peaks. Transient data attached are CSV files with column 1 being the pump-probe delay time (second), and column 2 being voltage response (V). The low noise amplifier gain of 15.527 dB must be accounted for June 28, 2017, December 18, 2017, and February 21, 2018 datasets and a gain of 15.91 dB must be accounted for the data file obtained on May 03, 2018 to yield the actual voltages. File with name “NCSU-Perovskite-CIDO-6-140GHz-3-26-RF-Average-FullLaserPower-June-28-2017” is obtained using a solid state IMPATT cavity **oscillator** operated at 140 GHz with 10 mW output power and after illuminating the sample with full laser power (22.14 mW). Filename: “NCSU-Perovskite-BWO-150GHz-1KHz-FullLaserPower-Dec-18-2017” is the average transient for the same sample obtained on December 18, 2017 but using an electrovacuum backward wave **oscillator** as probe source that is operated at 30% power level to transmit the same output power ~ 10 mW and further use of only about 0.32 mW for probing (in all cases using abeam splitter); Filename: “NCSU-Perovskite-BWO-150GHz-4096Sa-FullLaserPower-Feb-21-2018” is obtained for February 21, 2018 and filename: “NCSU-Perovskite-150GHz-BWO-1.6NDLaserPower-May-03-2018” is obtained in the same fashion as others except for the fact that the stimulating laser pulse fluence was reduced to ~ 0.3 microJoules per sq. cm. ... Hybrid organic-inorganic perovskite (HOIP) exhibit low cost, versatility in fabrication methods and possess good application potential because of high power conversion efficiency. Methylammonium lead Iodide (MAPbI3) with quartz substrate thin film sample (glass encapsulated) was obtained from NC State University have been used to obtain millimeter wave (mmw) transient response at probe **frequencies** of 140 and 150 GHz from CIDO and BWO sources respectively. The HOIP film was produced at NC State University on May 02, 2017. In our time-resolved TR-mmWC apparatus, the glass-covered sample was excited by a 1KHz triggered 532 nm laser beam with a width of 0.7 ns with maximum fluence 10 microJoules per sq. cm and a spot size of 10mm. Transient datasets were recorded using a 6 GHz input bandwidth digitizer after amplifying Schottky detector registered radiofrequency (RF) signal due to differential absorption of the passing millimeter wave from source (normal to sample) at 140 and 150 GHz through sample. Signal averaging was done 4096 times and data were collected on 4 different dates spanning 2, 6, and 8 months and 1 year from date of manufacture. A general trend of increase in radiative and trap-assisted recombination lifetimes of charge carriers was noted, and a decrease in amplitudes were also noted after fitting data by double exponential. The fits are obtained by adding a second excitation to account for double peaks. Transient data attached are CSV files with column 1 being the pump-probe delay time (second), and column 2 being voltage response (V).
