description: We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band $Hα$ photometry in the cluster region we have identified candidate young stellar objects (YSOs) distributed in a pattern from the cluster to one of the nearby nebulae Sim 129. The $V, (V-I)$ colour-magnitude diagram of the YSOs indicates that majority of these objects have ages between 1 to 5 Myr. The spread in the ages of the YSOs may indicate a non-coeval star formation in the cluster. The slope of the KLF for the cluster is estimated to be $0.34\pm0.07$, which agrees well with the average value ($\sim 0.4$) reported for young clusters. For the entire observed mass range $0.6 < M/M_\odot \le 17.7$ the value of the slope of the initial mass function, $`Γ$', comes out to be $-1.27\pm0.08$, which is in agreement with the Salpeter value of -1.35 in the solar neighborhood. However, the value of $`Γ$' for PMS phase stars (mass range $0.6 < M/M_\odot \le 2.0$) is found to be $-0.88\pm0.09$ which is shallower than the value ($-1.71\pm0.20$) obtained for MS stars having mass range $2.5 < M/M_\odot \le 17.7$ indicating a break in the slope of the mass function at $\sim 2 M_\odot$. Estimated $`Γ$' values indicate an effect of mass segregation for main-sequence stars, in the sense that massive stars are preferentially located towards the cluster center. The estimated dynamical evolution time is found to be greater than the age of the cluster, therefore the observed mass segregation in the cluster may be the imprint of the star formation process. There is evidence for triggered star formation in the region, which seems to govern initial morphology of the cluster.

VP16-01: Enhanced heating efficiency for hollow Fe3O4 spherical submicron particles
Creators: Takahiro Tsuji and Satoru Kobayashi
Publisher: name: IEEE
Year: 2023

Structured Materials and Magnetic Recording
Recently, magnetic particles with a vortex structure have received much attention as useful biomedical materials, because of high saturation magnetization and wider tunability of a particle size from sub-100 nm to submicrometer scale. The vortex particles showed a high heating efficiency, which is comparable to that of superparamagnetic nanoparticles [1] and is enhanced with the number of vortices [2]. Moreover, recent studies revealed a better stability of a vortex structure for hollow particles [3]. Here, we report results of micromagnetic simulations for hollow Fe3O4 submicron particles with variable particle morphology to seek the possible application of a hollow particle for magnetic hyperthermia. Micromagnetic simulations were performed using OOMMF 2.0 for spherical particle with an outer diameter Do of 100-700 nm, varying inner/outer diameter ratio of γ= 0-0.5. The typical magnetic parameters of Fe3O4 with <111> easy axes were used [3]. Alternating magnetic fields with an amplitude A up to 1.5 kOe and a frequency of 500 kHz were applied along the [100] axis. Fig. 1(a) shows M-H curves for A=1000 Oe for particles with γ = 0.5, but different Do. Unlike the M-H curve for Do =100 nm showing a high remanence, that for a larger Do exhibits a double hysteresis loop with an extremely low remanence, reflecting a better vortex stability at low fields. Interestingly, a specific absorption rate (SAR), calculated from the loop area, maximizes at Do~300 nm and attains 560 W/g for A=1000 Oe (inset of Fig. 1(a)). Moreover, the hysteresis loss (i.e. SAR) increases with increasing γ as shown in Fig. 1(b). This enhanced SAR for vortex particles with large γ was explained by strong irreversibility between vortex states with different orientation of the vortex axis, i.e. along the magnetic field and <111> easy axes (Fig.1(c)).References: [1] N.

AP-01: Valley polarized snake trajectories in anisotropic Weyl semimetals

Publisher: name: IEEE
Year: 2023

Fundamental Properties II: Magnetic Phase Transitions in 2D Systems and Complex Alloys
In the presence of spacially anti-symmetric out-of-plane magnetic fields, charged particles follow snake-like trajectories at the field boundary due to the coexistence of opposite-direction gauge potentials along the transport channel [1]. Previous works have shown that such configuration of gauge potentials can also be obtained with anti-symmetric pseudo-magnetic fields [2] or by applying a uniform magnetic field in the presence of a p-n junction [3]. The transport properties of snake states have been widely investigated in consideration of two-dimensional Dirac materials which generally respect crystal symmetry and exhibit isotropic energy dispersion. Here we calculate particle trajectories considering anisotropic Weyl semimetal with broken crystal symmetry and applied electrostatic potential where the barrier interface is parallel to the transport direction as illustrated in Fig. 1 (a). In the proposed model, the applied electrical potential (i.e., V0 = 2 EF, where Ef is the Fermi energy) effectively changes the carrier concentration on the half of the channel as illustrated in Fig. 1 (b) and results in Klein tunneling transport between electron and hole particles of which Fermi surfaces are shown in Fig. 1 (c). As a result, it is shown that the tilted anisotropic band structure of such materials breaks the valley degeneracy of snake state trajectories and thus two valleys with opposite chirality follow different paths with different velocities as shown in Fig. 1 (a).References: [1] L.

description: The sequence of phase transitions and the symmetry of in particular the low temperature incommensurate and spin-Peierls phases of the quasi one-dimensional inorganic spin-Peierls system TiOX (TiOBr and TiOCl) have been studied using inelastic light scattering experiments. The anomalous first-order character of the transition to the spin-Peierls phase is found to be a consequence of the different symmetries of the incommensurate and spin-Peierls (P$2_{1}/m$) phases. The pressure dependence of the lowest transition temperature strongly suggests that magnetic interchain interactions play an important role in the formation of the spin-Peierls and the incommensurate phases. Finally, a comparison of Raman data on VOCl to the TiOX spectra shows that the high energy scattering observed previously has a phononic origin.

description: We report on the electrostatic trapping of neutral SrF molecules. The molecules are captured from a cryogenic buffer-gas beam source into the moving traps of a 4.5 m long traveling-wave Stark decelerator. The SrF molecules in $X^2Σ^+(v=0, N=1)$ state are brought to rest as the velocity of the moving traps is gradually reduced from 190 m/s to zero. The molecules are held for up to 50 ms in multiple electric traps of the decelerator. The trapped packets have a volume (FWHM) of 1 mm$^{3}$ and a velocity spread of 5(1) m/s which corresponds to a temperature of $60(20)$ mK. Our result demonstrates a factor 3 increase in the molecular mass that has been Stark-decelerated and trapped. Heavy molecules (mass$>$100 amu) offer a highly increased sensitivity to probe physics beyond the Standard Model. This work significantly extends the species of neutral molecules of which slow beams can be created for collision studies, precision measurement and trapping experiments.
FR-08 : Tuning the structural and magnetic properties of iron oxide nanoparticles

Publisher: name: IEEE

Biomedical Applications II
Magnetic iron oxide nanoparticles (NPs) have gained significant attention in biomedical applications such as targeted drug delivery and hyperthermia therapy. This is due to their magnetic properties and non-toxic nature. Combining magnetic iron oxide NPs with plasmonic gold NPs, novel multifunctional nanomaterials can be produced. Depending on their oxidation states, iron may form various crystal structures, thus showing different magnetic properties. However, their magnetic properties in nanoscale may differ from the bulk behavior due to the finite size effect. Moreover, the synthesis of single-phase oxide NPs is challenging, often resulting in the presence of an oxidized layer at the surface. We observe a shift in the center of the hysteresis loops of iron oxide NPs. This is due to the exchange interaction between the magnetite core and a shell with disordered/oxidized surface spins. By comparing hysteresis loops cooled at different magnetic fields, a hardening effect is observed, i.e. the squareness and hardness of hysteresis loops is significantly enhanced with increasing magnetic cooling field. This indicates that an anisotropy axis is induced due to the exchange bias effect. To synthesize nanomaterials with tunable magnetic properties, it is important to understand how the crystallographic structure or the phase composition inside the NPs influences their magnetic properties. In this work, we performed systematic investigations on single iron oxide NPs as well as Au@FeOx multifunctional NPs with various sizes and shapes. The crystallographic structure and the magnetic properties of the samples were tuned by oxidation or reduction via different annealing procedures. From the X-ray absorptions spectroscopy results, one obtained the ratio of different iron oxide phases existing inside the particles. Anomalous small-angle X-ray scattering provides us with information about the size and thickness of core/shell structures. Combining these X-ray techniques with magnetometry, one can better understand the relationship between structural and magnetic properties. Furthermore, we studied the influence of a thin Au shell or a small Au NP attaching to the surface of the iron oxide NPs on their magnetic properties.

The purpose of this study is to extract and thoroughly analyze the resonance frequencies of magnetically-biased graphene scatterers in the THz band. Specifically, the application of an external magnetostatic bias field on graphene induces anisotropic effects caused by Lorentz forces acting on electrons. These effects reveal intriguing phenomena such as gyrotropy, non-reciprocity, and the support of magnetoplasmons [1]. Initially, a simple graphene disk is examined, and the fundamental frequencies are extracted for various applied bias fields. This process involves employing an appropriate eigenvalue formulation that enables the linear modeling of the 2D material's frequency-dispersive characteristics [2]. The extracted results for the first mode of the scatterer are depicted in Fig. 1, clearly illustrating that precise bias control can finely tune both the resonance frequency and the electromagnetic field pattern. The accurate evaluation of resonance modes in graphene scatterers enables the optimal design of more complex devices, such as metasurfaces. Specifically, tuning the bias fields appropriately modifies the device's performance based on the proximity of the operational frequency to the scatterer resonance. However, the periodic pattern of metasurfaces requires the utilization of multiple elementary cells in a periodic arrangement. Hence, our analysis extends to investigating the coupling between adjacent scatterers to assess their combined performance. Notably, the spiral electromagnetic pattern generated by the magnetically-biased scenario activates coupling in specific directions. Consequently, the metasurface exhibits increased adjustability, even in the case of a simple graphene disk scatterer, with additional degrees of freedom.References: [1] D. L.Sounas, and C.

description: Energy management is a critical aspect of risk assessment for Uncrewed Aerial Vehicle (UAV) flights, as a depleted battery during a flight brings almost guaranteed vehicle damage and a high risk of human injuries or property damage. Predicting the amount of energy a flight will consume is challenging as routing, weather, obstacles, and other factors affect the overall consumption. We develop a deep energy model for a UAV that uses Temporal Convolutional Networks to capture the time varying features while incorporating static contextual information. Our energy model is trained on a real world dataset and does not require segregating flights into regimes. We illustrate an improvement in power predictions by $29\%$ on test flights when compared to a state-of-the-art analytical method. Using the energy model, we can predict the energy usage for a given trajectory and evaluate the risk of running out of battery during flight. We propose using Conditional Value-at-Risk (CVaR) as a metric for quantifying this risk. We show that CVaR captures the risk associated with worst-case energy consumption on a nominal path by transforming the output distribution of Monte Carlo forward simulations into a risk space. Computing the CVaR on the risk-space distribution provides a metric that can evaluate the overall risk of a flight before take-off. Our energy model and risk evaluation method can improve flight safety and evaluate the coverage area from a proposed takeoff location.

In recent years, PM-assisted synchronous reluctance motor has received extensive attention, due to the merits of high torque density and power density [1]. However, due to the existence of PMs and multi-layer flux barriers in the d-axis, the d-axis inductance is relatively low, which limits the further improvement of the speed range [2]. Therefore, a reverse-salient multilayer flux barrier (RS-MFB) motor is proposed in this paper. In the proposed motor, by the artful design of the d-q-axis flux path, so that d-axis inductance can be increased effectively. It means that the speed range is further improved, and the power output capacity in the high-speed region is enhanced. In addition, due to its reverse-salient characteristics, RS-MFB motor works in the flux-intensifying region under rated operation condition, which increases the PM operation point and reduce irreversible demagnetization risk. Fig. 1 shows the structure and the simplified d-axis flux circuit of RS-MFB motor. In order to demonstrate the advantages of the proposed motor, the referenced PMASR motor is also investigated and compared. Fig. 2 shows the comparison of electromagnetic performances of two motors, including magnetic distribution, torque-current angle characteristic, inductance characteristic and torque/power-speed characteristics. It is observed that the output torque of the two motors reaches the maximum value at current phase angle +55° and -21°, which verifies that the PMASR motor operates in the deep flux-weakening region, while the RS-MFB motor operates in the flux-intensifying region. It is indicated that the PM operation point has been increased and irreversible demagnetization risk has been reduced. Furthermore, it is observed that the maximum output torque of the RS-MB is increased by 1.1Nm and torque ripple reduced from 24% to 10.3%，and the speed range widened by about 50%. In conclusion, it is noted that the proposed RS-MLF motor can realize improved output torque and widen speed range at the same time, which verify the assistance of d-q-axis design and he rationality of the RS-MLF motor design. More detailed analysis will be presented in the full paper.References: [1] T. A. Huynh, and M.

description: The complex Monoceros Loop SNR/Rosette Nebula region contains several potential sources of very-high-energy (VHE) gamma-ray emission and two as yet unidentified high-energy EGRET sources. Sensitive VHE observations are required to probe acceleration processes in this region. The H.E.S.S. telescope array has been used to search for very high-energy gamma-ray sources in this region. CO data from the NANTEN telescope were used to map the molecular clouds in the region, which could act as target material for gamma-ray production via hadronic interactions. We announce the discovery of a new gamma-ray source, HESS J0632+058, located close to the rim of the Monoceros SNR. This source is unresolved by H.E.S.S. and has no clear counterpart at other wavelengths but is possibly associated with the weak X-ray source 1RXS J063258.3+054857, the Be-star MWC 148 and/or the lower energy gamma-ray source 3EG J0634+0521. No evidence for an associated molecular cloud was found in the CO data.

description: We present an extensive catalog of non-parametric structural properties derived from optical and mid-infrared imaging for 4585 galaxies from the MaNGA survey. DESI and WISE imaging are used to extract surface brightness profiles in the g, r, z, W1, W2 photometric bands. Our optical photometry takes advantage of the automated algorithm AutoProf and probes surface brightnesses that typically reach below 29 mag/arcsec^2 in the r band, while our WISE photometry achieves 28 mag/arcsec^2 in the W1 band. Neighbour density measures and central/satellite classifications are also provided for a large sub-sample of the MaNGA galaxies. Highlights of our analysis of galaxy light profiles include: (i) an extensive comparison of galaxian structural properties that illustrates the robustness of non-parametric extraction of light profiles over parametric methods; (ii) the ubiquity of bimodal structural properties suggesting the existence of galaxy families in multiple dimensions; and, (iii) an appreciation that structural properties measured relative to total light, regardless of the fractional level, are uncertain. We study galaxy scaling relations based on photometric parameters, and present detailed comparisons with literature and theory. Salient features of this analysis include the near-constancy of the slope and scatter of the size-luminosity and size-stellar mass relations for late-type galaxies with wavelength, and the saturation of the central surface density, measured within 1 kpc, for elliptical galaxies with M* > 10.7 Msol (corresponding to Sigma_1 ~ 10^{10} Msol/kpc^2). The multi-band photometry, environmental parameters, and structural scaling relations presented are useful constraints for stellar population and galaxy formation models.

description: We rigorously study the long time dynamics of solitary wave solutions of the nonlinear Schrödinger equation in {\it time-dependent} external potentials. To set the stage, we first establish the well-posedness of the Cauchy problem for a generalized nonautonomous nonlinear Schrödinger equation. We then show that in the {\it space-adiabatic} regime where the external potential varies slowly in space compared to the size of the soliton, the dynamics of the center of the soliton is described by Hamilton's equations, plus terms due to radiation damping. We finally remark on two physical applications of our analysis. The first is adiabatic transportation of solitons, and the second is Mathieu instability of trapped solitons due to time-periodic perturbations.

description: Der Kostendruck bei der Getreideernte nimmt weiter zu. Die Sicherung des Betriebseinkommens ist durch Erzeugung größerer Erntemengen (höhere Erträge und mehr Anbauflächen) sowie Einsparungen (höhere Flächenleistungen und gute Einsatzplanung des Mähdreschers) möglich. Durch schüttlerlose Mähdrescher, Mehrtrommeldreschwerke, Verbesserung der Reinigungsanlage und Vergrößerung der Korntankinhalte bei nahezu gleicher Entleerungszeit konnte in den letzten Jahren die Flächenleistung weiter gesteigert werden. Dies bewirkte auch eine Erhöhung der Motorleistung, Weiterentwicklung der Schneidwerke und eine Verbesserung der Arbeitsbedingungen für den Fahrer durch einen gutgestalteten Arbeitsplatz, durch Informationssysteme und durch zum Teil automatische Regelungs- und Einstelleinrichtungen.

description: We show that temperature and magnetic field properties of the entanglement between spins on the two-dimensional Shastry-Sutherland lattice can be qualitatively described by analytical results for a qubit tetramer. Exact diagonalization of clusters with up to 20 sites reveals that the regime of fully entangled neighboring pairs coincides with the regime of finite spin gap in the spectrum. Additionally, the results for the regime of vanishing spin gap are discussed and related to the Heisenberg limit of the model.

Ferrite is a widely applied magnetic core material in transformers and inductors. It exhibits strong temperature-dependence, with significant differences in loss under various temperature conditions[1-2]. Therefore, it is necessary to establish an accurate hysteresis model that takes into consideration the effects of temperature. In this paper, an improved Recurrent Neural Network model based on the Play hysteresis operator has been proposed, which is able to predict the hysteresis loops of ferromagnetic materials at different temperatures. The results demonstrated that the modified model has the benefits of high identification accuracy, fast convergence speed and extensively applicable. In order to evaluate the influence of temperature on the magnetic properties of ferrite, the ring sample has been adopted to measure the hysteresis loop of ferrite manufactured by Tokyo Denkikagaku Kogyo (TDK) from room temperature (25°C) to 120°C. The sample at different temperatures have reached the saturation magnetization state under the given excitation conditions. All hysteresis loops under the temperature of 25°C and 50°C were selected to constitute the training set of the neural network for material feature extraction. In order to determine whether the model is overfitting, the validation set of the model takes the measurement data at 75°C , while the experimental data at 100°C and 120°C were used as the test set to test the validation of the model. Fig.1 shows the schematic of the improved recurrent neural network. The improved model adopts the Mean Squared Error Loss (MSELoss) as the assessment benchmark. The MSELoss between predicted value and experimental value is 0.14% and 0.29% at 100°C and 120°C. Fig.2 shows a comparison between measured and predicted values of the ferrite at different magnetic flux densities at 100°C. Further results will be presented in the full paper. Moreover, these results suggest that the proposed model has significant scalability to various magnetic materials at different temperature, while it has the capacity to predict the magnetization characteristics at complex working conditions.References: [1]Nouicer A, Nouicer E, Feliachi M.

description: We apply a singularity resolution technique utilized in loop quantum gravity to the polymer representation of quantum mechanics on R with the singular -1/|x| potential. On an equispaced lattice, the resulting eigenvalue problem is identical to a finite difference approximation of the Schrodinger equation. We find numerically that the antisymmetric sector has an energy spectrum that converges to the usual Coulomb spectrum as the lattice spacing is reduced. For the symmetric sector, in contrast, the effect of the lattice spacing is similar to that of a continuum self-adjointness boundary condition at x=0, and its effect on the ground state is significant even if the spacing is much below the Bohr radius. Boundary conditions at the singularity thus have a significant effect on the polymer quantization spectrum even after the singularity has been regularized.

description: Es wird über Grundlagenuntersuchungen zur Klärung der Wirkung und Funktionsweise einer Fallstufe berichtet. Die Strömungsrichtung und die Geschwindigkeit des Luftstrahles in der Fallstufe haben Einfluss auf die Leistungsfähigkeit der Reinigungsanlage, wenn die Lufteinstellung am Siebanfang für die Gutauflockerung nicht ausreichend ist. Mit einer steiler gerichteten Luftströmung wird die Gutauflockerung begünstigt. Bei hohem Gutdurchsatz ist eine steilere Luftströmung in der Fallstufe für die Gutauflockerung und Kornabscheidung günstiger.

description: Die klimatischen Bedingungen in Verkaufsräumen sind meist ungeeignet für Obst und Gemüse. Verdunstungskühlung bietet sich als Möglichkeit an, um die Präsentationsbedingungen von Frischmarktprodukten bei der Direktvermarktung deutlich zu verbessern. In einer Versuchsanlage mit Ultraschallvernebler konnte die Wasserdampfpartialdruckdifferenz zwischen der Gemüseoberfläche und der umgebenden Luft um mehr als 80 % verringert werden. Dadurch sanken die Transpirationsverluste bei Kopfsalat nach fünf Stunden Lagerzeit von 12 auf 2 %. Entsprechend den jeweiligen Anforderungen können Einfachlösungen für die Direktvermarktung bis hin zu anspruchsvollen Varianten konzipiert werden.

description: Der niedrige Energiegehalt von Halmgut legt dessen Verdichtung sowie Bergung mit Restwassergehalten unter 20 % nahe. Dazu sollte die Biomasse möglichst bei niedriger relativer Luftfeuchte und Schönwetter geerntet werden, um gegebenenfalls eine Bodentrocknung zu ermöglichen. Von hoher relativer Vorzüglichkeit sind Großballen und hier insbesondere Quaderballenvarianten. Deren Überlegenheit resultiert aus dem schlagkräftigen Zusammenspiel der Technik, dem guten Preis-Leistungs-Verhältnis moderner Pressen sowie der Möglichkeit der kompakten Offenlagerung der Ballen.

description: In Kenntnis der biotechnischen Rahmenbedingungen wurden neue Anbausysteme zur Erzeugung von technisch nutzbaren Kurzfasern entwickelt und erprobt. Die Einflüsse von Sorte, Standort und Jahr auf Faserertrag und Qualität der Kurzfasern verlangen eine flexible Verfahrenstechnik von Anbau, Ernte und Aufbereitung. Standort- und Jahreseinfluss zeigen, dass ein Vorhalten und Mischen von Faserpartien verschiedener Standorte und Jahre notwendig ist, um eine gleichbleibende und hohe Qualität zu erzeugen. Mit den Naturfasern aus ungeröstetem Leinstroh können synthetische Fasern in Verbundwerkstoffen ersetzt werden.

description: Recent multi-wavelength ALMA observations of the protoplanetary disk orbiting around Elias 2-27 revealed a two armed spiral structure. The observed morphology together with the young age of the star and the disk-to-star mass ratio estimated from dust continuum emission make this system a perfect laboratory to investigate the role of self-gravity in the early phases of star formation. This is particularly interesting if we consider that gravitational instabilities could be a fundamental first step for the formation of planetesimals and planets. In this Letter, we model the rotation curve obtained by CO data of Elias 2-27 with a theoretical rotation curve including both the disk self-gravity and the star contribution to the gravitational potential. We compare this model with a purely Keplerian one and with a simple power-law function. We find that (especially for the $^{13}$CO isotopologue) the rotation curve is better described by considering not only the star, but also the disk self-gravity. We are thus able to obtain for the first time a dynamical estimate of the disk mass of $0.08\pm0.04\,M_{\odot}$ and the star mass of $0.46\pm0.03\,M_{\odot}$ (in the more general case), the latter being comparable with previous estimates. From these values, we derive that the disk is 17$\%$ of the star mass, meaning that it could be prone to gravitational instabilities. This result would strongly support the hypothesis that the two spiral arms are generated by gravitational instabilities.

description: Um den Einfluss der Sauerstoffkonzentration auf die Reaktionskinetik und auf das Emissionsverhalten bei der Kompostierung tierischer Exkremente zu untersuchen, wurden drei geschlossene, wärmegedämmte Reaktoren mit aktiver Belüftung gebaut. Die Abbaugeschwindigkeit organischen Kohlenstoffs beschleunigte sich um 20 bis 30 %, wenn die Sauerstoffkonzentration in der Zuluft von 21 auf 25 Vol.-% stieg. Das gleiche Ergebnis konnte auch durch Erhöhung der Belüftungsrate erzielt werden, dabei musste eine überproportionale Steigerung der Ammoniakemission in Kauf genommen werden. Unter anoxischen Bedingungen entstanden Lachgasemissionen, die ab einer Sauerstoffkonzentration unter 3 Vol.-% sprunghaft anstiegen.

description: In models with large extra dimensions, black holes may be produced in high-energy particle collisions. We revisit the physics of black hole formation in extensive airshowers from ultrahigh-energy cosmic rays, focusing on collisional QCD and black hole emissivity effects. New results for rotating black holes are presented. Monte Carlo simulations show that QCD effects and black hole spin produce no observable signatures in airshowers. These results further confirm that the main characteristics of black hole-induced airshowers do not depend on the fine details of micro black hole models.

description: Short pulse lasers are used to characterize the nonlinear response of amplified photodetectors. Two widely used balanced detectors are characterized in terms of amplitude, area, broadening, and balancing the mismatch of their impulse response. The dynamic impact of pulses on the detector is also discussed. It is demonstrated that using photodetectors with short pulses triggers nonlinearities even when the source average power is well below the detector continuous power saturation threshold.
