Multi-Functional Magnetic Materials and Applications I
Magnetic refrigeration based on the magnetocaloric effect has the potential to significantly improve energy efficiency of existing vapor-compression-based temperature control systems, while being environmentally benign. However, the existing measurement methods, direct (adiabatic temperature changes under magnetization/demagnetization) and indirect (heat capacity or isothermal magnetization measurements), have large uncertainties (30% or more) and a large discrepancy in values. For example, the adiabatic temperature change for gadolinium varies between 3.9 K to 5.8 K using a field change of about 2 T. To progress, this technology requires a clear connection between the properties of the magneto-caloric materials (MCMs) and their performance in the magnetic refrigeration cycle. Therefore, we are proposing a new instrument and measurement method to directly measure the refrigeration capacity of MCMs with acceptable uncertainties: a pressure-energy rig that uses the incompressibility of a fluid as an amplifier to increase the sensitivity of the measurement. In this method, a chamber is moved into/out of an applied magnetic field (Fig. 1). The sample chamber is made of pure diamagnetic glass to eliminate eddy current heating and minimize changes to the magnetic field seen by the sample, and is surrounded by a (high) vacuum jacket to make the chamber quasi-adiabatic. A glass “fence” is in the center of the sample chamber to hold the sample stationary while the actuator is operating, but maintains good thermal contact with the surrounding fluid. The sample surface, sample center, and chamber walls have their temperatures monitored to measure heat in/from the sample. A non-magnetic pressure sensor measures the pressure change in the fluid around the sample, and it can also be used to verify the maximum sample temperature change. The measurement technique is calibrated by comparison with the sample temperature rise from the injection of a known amount of heat, provided by a known applied current to a heater of known resistance located in the center of the sample. Preliminary results for Gd at room temperature are 2.5 K for a 1 T field change.

description: A classical paradox in high-mass star formation is that powerful radiation pressure can halt accretion, preventing further growth of a central star. Disk accretion has been proposed to solve this problem, but the disks and the accretion process in high-mass star formation are poorly understood. We executed high-resolution ($R$=35,000-70,000) iSHELL spectroscopy in $K$-band for eleven high-mass protostars. Br-$γ$ emission was observed toward eight sources, and the line profiles for most of these sources are similar to those of low-mass PMS stars. Using an empirical relationship between the Br-$γ$ and accretion luminosities, we tentatively estimate disk accretion rates ranging from $\lesssim$10$^{-8}$ and $\sim$10$^{-4}$ $M_\odot$ yr$^{-1}$. These low-mass-accretion rates suggest that high-mass protostars gain more mass via episodic accretion as proposed for low-mass protostars. Given the detection limits, CO overtone emission ($v$=2-0 and 3-1), likely associated with the inner disk region ($r \ll 100$ au), was found towards two sources. This low-detection rate compared with Br-$γ$ emission is consistent with previous observations. Ten out of the eleven sources show absorption at the $v$=0-2 ${\rm R(7)-R(14)}$ CO R-branch. Most of them are either blueshifted or redshifted, indicating that the absorption is associated with an outflow or an inflow with a velocity of up to $\sim50$ km s$^{-1}$. Our analysis indicates that the absorption layer is well thermalized (and therefore $n_{\mathrm H_2} \gtrsim 10^6$ cm$^{-3}$) at a single temperature of typically 100-200 K, and located within 200-600 au of the star.

Planners and negotiation

description: This thesis analyzes the role of negotiation theory and skills training in planning school curricula. This analysis is based on (1) a literature review focusing on planning, managing and negotiating and (2) a survey on negotiation and dispute resolution in North American planning schools. The literature review indicates that negotiation is a foundation skill for planners. Planning and managing are functions performed by planners. Both functions involve political decision making and political communication. Conflict situations are inevitable in political work environments, and negotiation is significant as a way to manage conflict. Hence, planners should have negotiating skills. However, very few planners have, at any stage of their development, been made aware of the range of negotiation theories, roles, strategies or tactics they might adopt. Prominent planning educators such as Baum, Forester, Schon and Susskind have raised a concern that many planners lack negotiating skills. They point to education as a solution. Based on the survey results, at least 25 percent of Canadian and 15 percent of American planning schools now offer one or more courses in these subjects. These courses began to emerge in 1981-1982. An analysis of the curricula materials collected indicates that these courses are based on the cooperative, problem solving approach advocated in two popular American books - namely: (1) "Getting to Yes" by Fisher and Ury and (2) "The Art and Science of Negotiation" by Raiffa. The main recommendation of this thesis is that planning educators recognize the need to equip planners with a basic level of negotiation theory and skill training. The development of negotiating skills depends on learning appropriate kinds of behaviour. Learning is facilitated by practice and exposure to simulated problem solving situations.

Magnetocaloric refrigeration is a promising alternative to gas-based cooling systems, providing enhanced energy efficiency and reduced environmental impact. FeRh is a standout magnetocaloric material with the largest magnetocaloric effect due to the AFM-FM phase transition. The desired magnetocaloric response in FeRh structures depends on the composition and processing conditions.[1] In this contribution we present a comprehensive pathway for creating FeRh magnetocaloric microstructures by laser processing (Fig. 1). γ-FeRh nanoparticles with reduced oxidation are synthesized via picosecond pulsed laser ablation in ethanol (Fig. 1a).[2] These nanoparticles are employed to create 1 wt.% ethanol-FeRh ink which is then dispersed on PVP-coated glass substrates and subsequently patterned using a continuous wave laser (Fig. 1b and c). Laser-based direct writing facilitates sintering into custom structures (Fig. 2a) and partially induces the γ-FeRh to B2-FeRh phase transition.[3,4] A 52% partial phase transformation can be achieved, resulting in a significant magnetization increase of ca. 35 Am2/kg during the field-induced AFM-FM transition (Fig. 2b). Notably, laser sintering demonstrates a remarkable sixfold enhancement of the achieved magnetization compared to furnace annealed FeRh ink which measured ca. 6Am2/kg. This study presents a robust and efficient approach to generate magnetocaloric structures. Laser synthesis and sintering enable the production of diverse FeRh-based microstructures with high spatial resolution, in-situ annealing, and design flexibility (Fig. 2a). These advancements hold promise for the development of miniaturized devices like magnetic microcoolers, thermal sensors, and magnetic micropumps, leveraging pronounced magnetocaloric effects at a small scale.References: [1] S.Nikitin, G.Myalikgulyev, A.Tishin, Physics Letters A 148, 363–366 (1990) [2] R.

Structured Materials and Magnetic Recording
Heusler alloys attracted extensive attention due to their novel properties like tunable composition and electronic structure which makes them suitable for applications in spintronics and superconductivity[1-2]. One-dimensional nanostructures are advantageous for rapid production, high performance and device miniaturization[3]. The present study uses an inexpensive electrodeposition technique at ambient temperature to fabricate Co2FeGa Heusler alloy nanowires (HANWs) in anodic alumina templates (AAO). The influence of deposition parameter i.e. electrolyte solution's potential was optimized to achieve appropriate stoichiometry of HANWs. The structural, morphological, static and dynamic magnetic properties were investigated as a function of deposition potential for HANWs. The formation of Heusler alloy phase was confirmed by the X-ray diffraction pattern which indicates the B2 type crystal structure(Fig. 1). The most intense peak was observed for (220) reflection plane in the diffraction spectra for all samples. From morphological analysis, it was revealed that the nanowires were uniformly deposited in the AAO templates. The quantitative analysis using EDX confirmed the best stoichiometry for full Heusler alloy (X2YZ) was obtained for –2V deposition potential. Fig.1 (inset) depicts the atomic percentage of HANWs for different deposition potentials. Magnetic properties derived from hysteresis loop of HANWs are saturation magnetization, remanence and coercivity. The dynamic properties were obtained using ferromagnetic resonance (FMR) measurements in flip-chip geometry in field-sweep mode. Fig.2 shows that the resonance field first decreases with the increase of deposition potential and then increases slightly with further increase in potential. Fig. 2 (inset) shows the resonance linewidth for all the deposition potentials. Various intrinsic parameters such as Gyromagnetic ratio, inhomogeneity and Gilbert damping constant were derived from the FMR data. It was observed that the Gilbert damping was minimum for appropriate stoichiometric Co2FeGa NWs obtained at deposition potential of –2V.References: [1] Elphick, K., Frost, W., Samiepour et al.

Magnetic Sensors and High Frequency Devices
In telecommunication technology, transmitting and receiving signal is not possible without integrating antenna [1]. Miniaturized tunable multi-band microwave devices can be realized by incorporating ferromagnetic materials that exhibit both low loss and high permeability at gigahertz frequencies. A circular ring antenna with a compact size of 25 x 25 mm2, fed by a microstrip line is proposed at 12 GHz. The antenna is composed of a circular- ring resonator and Gd(x)-doped YIG thin disks (x= 0.0, 0.1, 0.2, 0.3) placed over the ring. It provides tunable operation over tri-band (C to Ku) due to the photon-magnon coupling which enables coherent qubit information transmission from an electromagnetic (EM) carrier to the magnetostatic spin oscillations (magnons) of a magnetic material [2]. The proposed antenna is validated using HFSS simulation. To characterize the frequency tunability of the designed antenna, we measured the return loss (S11) as a function of dc magnetic field. Different concentration Gd-doped YIG ferrites have been loaded on ring antenna to observe strong anti-crossing phenomena with the application of external magnetic field (Fig. 1) for Gd0.2-YIG sample( inset: schematic of antenna). The designed antenna has a tunability of around 300% for an applied magnetic field up to 3.7 kOe. The maximum gain of dual resonance antenna is 1.4 for higher magnetic field. Fig. 2 represents the measured normal mode splitting spectrum as a function of bias magnetic field that gives the coupling distance of 1.29 for Gd0.2-YIG sample. The inset of Fig 2 shows the efficiency and bandwidth % as a function of Gd concentration. It is apparent that they are maximum for Gd0.3-YIG. The radiation patterns of the antenna with all the samples indicated exhibit omnidirectional characteristic, which suggested that the signal could be received by this antenna in various positions. Such antenna are suitable candidates for use in multi-band applications.References: [1] Hasan, I. H., Hamidon, M. N., Ismail, A., et al. IEEE Access, 6, 32601, 2018.

description: Since the 1990’s, the role of knowledge and science as incentives of modernization during the 20th century has increasingly become investigated by historians. Seemingly trade unions, and the labour movement as a whole, have not been among the forerunners of such developments. Contrary to this perception, this article analyses efforts of the German trade union movement to scientifically penetrate the mechanisms of market capitalism long before the foundation of the well known “Wirtschafts- und Sozialwissenschaftliches Institut” (WSI) on the initiative of Hans Böckler as early as April 1946. It becomes apparent that, on the grounds of a deeply rooted trade union interest in social statistics and legal conditions of work, a network of young economists and social scientists has evolved since the 1920’s that, partially related to some rather open-minded academic institutes, actively reconstructed such efforts on Böckler’s incentive. Thus, the influential WSI rests in a mainstream of “scientification” of politics troughout the 20th century.

Accurate topology data is an important foundation for the optimization of distribution network operation mode, fault handling, line loss calculation and other applications [1]. The active injection method of characteristic current is an effective technique used in power systems for topology and fault detection [2,3]. This method provides accurate fault location information, which aids in the quick troubleshooting, reduction of downtime, and improvement of power system reliability. However, detecting the frequency and amplitude of the characteristic current signal imposes strict requirements. On one hand, the frequency of characteristic current should not be too high or too low. High-frequency signals attenuate rapidly, while low-frequency signals are susceptible to the interference from power frequency harmonics. On the other hand, injecting large current signals can easily interfere with power frequency signals, while extremely weak current signals are limited by the sensitivity of existing current sensors, leading to a decrease in identification accuracy. The Micro-Electro-Mechanical Systems (MEMS) magnetoelectric(ME) sensors offer advantages such as high sensitivity, excellent frequency selectivity, and low power consumption, enabling effective measurement of weak current [4, 5]. In order to improve the accuracy and reliability of distribution network topology identification, we proposed a new recognition strategy based on low-frequency resonant ME sensors. Fig. 1 displays the topology identification diagram of power distribution network. In this work, we designed, fabricated, and tested the ME sensor that operates at 229Hz and has a current limit of detection (LoD) of 20 uA, as shown in Fig. 2. We also measured the mixed signal of 50Hz power frequency current and 229Hz characteristic current, in which the weak characteristic signal of 1mA has the same output voltage as that of the power frequency current of 1A. This means the low-frequency resonant ME sensors are a promising candidate for topology identification of power distribution network.References: [1] Fan, J., & Borlase, S..

Domain Wall, Vortex, and Skyrmion Dynamics and Devices (Virtual)
Skyrmions are being examined in chambers for potential computing applications, including reservoir computing and random bitstream generation at the chamber's output [1, 2]. A detailed analysis of skyrmion stochasticity in these chambers is required to understand how skyrmions respond to changes in temperature, grain sizes, and current densities, specifically with regard to their motion and pinning effects. This research presents a comprehensive investigation into the stochastic behavior of skyrmion shuffling chambers (Fig. 1), considering realistic material variations and temperature effects for potential neuromorphic computing applications. The simulations based on MuMax3 reveal that the skyrmion's diameter influences stochasticity and that the skyrmion's trajectory can be altered without changing its diameter through local temperature control. This ability to dynamically adjust the skyrmion shuffling chamber's input/output properties and stochasticity using temperature offers an additional level of control for neuromorphic computing applications. Moreover, the observed behavior of the shuffling device aligns with the integrate and fire neuron model. Based on this simulation platform, the skyrmion chamber shows new dynamic behaviors when operational parameters are changed, e.g., induced stochastic skyrmion motion within a single chamber and alterations in the longevity of the skyrmion path [3]. We then expand the simulation platform to include three side-by-side chambers which shows a novel function for the skyrmion chamber. It can act as an artificial synapse with spike-timing-dependent plasticity (STDP) response, where the synapse weight correlates with the number of skyrmions in the center chamber (Fig. 2). The device allows for varying rates of weight updates based on skyrmion dynamics and applied currents, enabling the device to mimic different forms of synaptic plasticities, such as Hebbian and dendritic location-based plasticity. This work explores neuromorphic systems, focusing on creating efficient and adaptable non-volatile devices for machine learning and spiking neural networks, while also developing tunable probabilistic computing devices and artificial synapses utilizing magnetic skyrmions.References: [1] Zázvorka et al.

Spin Orbitronics II
The Dzyaloshinskii-Moriya interaction (DMI) is an antisymmetric exchange that stabilizes magnetization textures, such as skyrmions and merons, assists spin-orbit torques, and modifies several magnetic properties [1,2]. The DMI was predicted in 1958 [3], but the emergence of this coupling in complex materials and interfaces, as well as the tunning of its strength and symmetries, are still under active investigation. This presentation investigates the DMI of metals and interfaces containing rare-earth atoms (lanthanides), such as Dy and Tb. These atoms are heavy and possess a strong spin-orbit interaction which induces antisymmetric exchange, i.e., a DMI [4,5]. The starting point of our study is a model consisting of two magnetic atoms in an electron gas, one of them being a rare earth [5]. Each atom creates a conduction-electron spin polarization along its spin direction, but the rare earth tilts this spin polarization due to the spin-orbit coupling [5]. The result is an anisotropic spin density, orthogonal to both atomic spins, that we name Dzyaloshinskii-Moriya Spin Density (DM-SD). Figure 1 shows this spin density. Then, when adding a third impurity to the electron gas, its spin locally interacts with the DM-SD giving rise to the DMI. Therefore, the DM-SD is the antisymmetric equivalent of the RKKY spin density that mediates the isotropic exchange between two distant spins in metals. The simplicity of this model allows its use in more general situations, such as rare-earth-containing interfaces between magnetic insulators and transition-metal magnets. Furthermore, if the rare-earth atom is replaced by a transition metal with a partially unquenched orbital momentum, the magnitude of the DM-SD is reduced from the one of rare earths.

description: In a relativistic context, the main purpose of Extended Irreversible Thermodynamics (EIT) is to generalize the principles of non-equilibrium thermodynamics to the domain of fluid dynamics. In particular, the theory aims at modelling any diffusion-type process (like heat as diffusion of energy, viscosity as diffusion of momentum, charge-conductivity as diffusion of particles) directly from thermodynamic laws. Although in Newtonian physics this task can be achieved with a first-order approach to dissipation (i.e. Navier-Stokes-Fourier like equations), in a relativistic framework the relativity of simultaneity poses serious challenges to the first-order methodology, originating instabilities which are, instead, naturally eliminated within EIT. The first part of this work is dedicated to reviewing the most recent progress made in understanding the mathematical origin of this instability problem. In the second part, we present the formalism that arises by promoting non-equilibrium thermodynamics to a classical effective field theory. We call this approach Unified Extended Irreversible Thermodynamics (UEIT), because it contains, as particular cases, EIT itself, in particular the Israel-Stewart theory and the divergence-type theories, plus Carter's approach and most branches of non-equilibrium thermodynamics, such as relativistic chemistry and radiation hydrodynamics. We use this formalism to explain why all these theories are stable by construction (provided that the microscopic input is correct), showing that their (Lyapunov) stability is a direct consequence of the second law of thermodynamics.

description: In this paper we consider quiver gauge theories with fractional branes whose infrared dynamics removes the classical supersymmetric vacua (DSB branes). We show that addition of flavors to these theories (via additional non-compact branes) leads to local meta-stable supersymmetry breaking minima, closely related to those of SQCD with massive flavors. We simplify the study of the one-loop lifting of the accidental classical flat directions by direct computation of the pseudomoduli masses via Feynman diagrams. This new approach allows to obtain analytic results for all these theories. This work extends the results for the $dP_1$ theory in hep-th/0607218. The new approach allows to generalize the computation to general examples of DSB branes, and for arbitrary values of the superpotential couplings.

description: The ground state entanglement entropy between block of sites in the random Ising chain is studied by means of the Von Neumann entropy. We show that in presence of strong correlations between the disordered couplings and local magnetic fields the entanglement increases and becomes larger than in the ordered case. The different behavior with respect to the uncorrelated disordered model is due to the drastic change of the ground state properties. The same result holds also for the random 3-state quantum Potts model.

description: I discuss low energy aspects of heavy meson decays, where there is at least one heavy meson in the final state. Examples are $B -\bar{B}$ mixing, $B \to D \bar{D}$, $B \to D η'$, and $B \to D γ$. %and $B \to D W $ (Isgur-Wise function). The analysis is performed in the heavy quark limit within heavy-light chiral perturbation theory.

description: Motivated by the interpretation of the Ooguri-Strominger-Vafa conjecture as a holographic correspondence in the mini-superspace approximation, we study the radial quantization of stationary, spherically symmetric black holes in four dimensions. A key ingredient is the classical equivalence between the radial evolution equation and geodesic motion of a fiducial particle on the moduli space M^*_3 of the three-dimensional theory after reduction along the time direction. In the case of N=2 supergravity, M^*_3 is a para-quaternionic-Kahler manifold; in this case, we show that BPS black holes correspond to a particular class of geodesics which lift holomorphically to the twistor space Z of M^*_3, and identify Z as the BPS phase space. We give a natural quantization of the BPS phase space in terms of the sheaf cohomology of Z, and compute the exact wave function of a BPS black hole with fixed electric and magnetic charges in this framework. We comment on the relation to the topological string amplitude, extensions to N>2 supergravity theories, and applications to automorphic black hole partition functions.

description: We investigate the acceleration and simultaneous radiative losses of electrons in the vicinity of relativistic shocks. Particles undergo pitch angle diffusion, gaining energy as they cross the shock by the Fermi mechanism and also emitting synchrotron radiation in the ambient magnetic field. A semi-analytic approach is developed which allows us to consider the behaviour of the shape of the spectral cut-off and the variation of that cut-off with the particle pitch angle. The implications for the synchrotron emission of relativistic jets, such as those in gamma ray burst sources and blazars, are discussed.

description: The impact of the ongoing COVID-19 pandemic is being felt in all spheres of our lives -- cutting across the boundaries of nation, wealth, religions or race. From the time of the first detection of infection among the public, the virus spread though almost all the countries in the world in a short period of time. With humans as the carrier of the virus, the spreading process necessarily depends on the their mobility after being infected. Not only in the primary spreading process, but also in the subsequent spreading of the mutant variants, human mobility plays a central role in the dynamics. Therefore, on one hand travel restrictions of varying degree were imposed and are still being imposed, by various countries both nationally and internationally. On the other hand, these restrictions have severe fall outs in businesses and livelihood in general. Therefore, it is an optimization process, exercised on a global scale, with multiple changing variables. Here we review the techniques and their effects on optimization or proposed optimizations of human mobility in different scales, carried out by data driven, machine learning and model approaches.

Magnetic Sensors and High Frequency Devices (Virtual)
An ultra-sensitive magnetic current sensor in a smart grid is a device used to measure and monitor electric currents with high precision and sensitivity. It is an essential component in the power grid infrastructure, enabling accurate current measurement and monitoring. The sensor utilizes the principle of magnetic field sensing to measure electric currents. Its core is composed of magnetoelectric stress-coupled magnetic field sensors, with a strong coupling coefficient and excellent frequency selection performance [1,2]. When an electric current flows through a conductor, it generates a magnetic field around it. The magnetic current sensor detects and measures this magnetic field to determine the magnitude and direction of the current. The ultra-sensitivity of these sensors allows them to detect extremely small current levels, typically in the range of mA to μA accurately [3,4]. This level of sensitivity is crucial in smart grid applications where precise current measurement is required, especially in situations involving partial discharge monitoring, fault detection, and topology identification. Fig. 1 shows the schematic diagram of the application of ultra-sensitive magneto-sensitive current sensors in grounding fault detection. By injecting characteristic small current signals of different frequencies, a path is formed between the injection point and the grounding point, the sensors can effectively identify the characteristic current signal for fault detection. The sensitivity of the sensor is very important to the process of ground fault discrimination. We have achieved a high-sensitivity linear measurement of 20μA-200mA, as shown in Table 1. And it already has the ability to identify the characteristic frequency current in the complex background current situation, which will play an important role in early fault detection.References: [1] Xiao N, Wang Y, Chen L, et al.

DP-12: Suppression of in-plane (001) texture component in FePt-oxide granular films by adding a carbon buffer layer

Structured Materials and Magnetic Recording
The L10 type FePt phase is attracting attention as the heat assisted magnetic recording medium material due to its high uniaxial crystalline magnetic anisotropy energy of 5×107 erg/cm3 at room temperature. To obtain a granular structure with fine columnar and isolated magnetic grains, high c-axis orientation, and high degree of order, the research of adding various grain boundary materials (GBMs), such as C1,2), SiO23), TiO24), MgO5), Ta2O56), B2O37) into FePt thin films have been widely conducted. Based on our previous study, most of FePt granular films with oxides have high ratio of in-plane (001) texture component8) than that of with C. Many reports show that the in-plane component is induced by surface roughness, grain size, crystal orientation of MgO underlayer9). To address this issue, we have carried out an experiment to avoid a direct contact between MgO underlayer and oxide GBM by adding a buffer layer in between those layers. In this paper, we will report the evaluation result of nanostructure and magnetic properties of the granular films added with a carbon buffer layer. Fig. 1 shows M-H loops of FePt-B2O3 granular films with various C buffer thickness. Film structure is shown in the inset. Larger hysteresis can be observed with addition of a C buffer layer (0.6 nm). With further increase in thickness of the C buffer layer (1.0 nm), the hysteresis becomes smaller. This suggests that the employment of the thin C buffer layer is effective to improve magnetic properties. Fig. 2 shows in-plane XRD profiles for FePt-B2O3 granular films with various various C buffer thickness. For all films, mainly, the (110), (200), and (220) diffractions from L10-FePt phase are observed, which indicates that FePt grains have c-plane sheet texture. Concerning other diffractions, the integral intensities of (001) diffraction for FePt-B2O3 granular films with the C buffer layer (> 0.6 nm) is significantly reduced which indicates that the ratio of FePt grains with their c-axes parallel to film normal is reduced by using the C buffer layer.References: 1) J.

description: Neurodegenerative parkinsonism can be assessed by dopamine transporter single photon emission computed tomography (DaT-SPECT). Although generating images is time consuming, these images can show interobserver variability and they have been visually interpreted by nuclear medicine physicians to date. Accordingly, this study aims to provide an automatic and robust method based on Diffusion Maps and machine learning classifiers to classify the SPECT images into two types, namely Normal and Abnormal DaT-SPECT image groups. In the proposed method, the 3D images of N patients are mapped to an N by N pairwise distance matrix and are visualized in Diffusion Maps coordinates. The images of the training set are embedded into a low-dimensional space by using diffusion maps. Moreover, we use Nyström's out-of-sample extension, which embeds new sample points as the testing set in the reduced space. Testing samples in the embedded space are then classified into two types through the ensemble classifier with Linear Discriminant Analysis (LDA) and voting procedure through twenty-five-fold cross-validation results. The feasibility of the method is demonstrated via Parkinsonism Progression Markers Initiative (PPMI) dataset of 1097 subjects and a clinical cohort from Kaohsiung Chang Gung Memorial Hospital (KCGMH-TW) of 630 patients. We compare performances using Diffusion Maps with those of three alternative manifold methods for dimension reduction, namely Locally Linear Embedding (LLE), Isomorphic Mapping Algorithm (Isomap), and Kernel Principal Component Analysis (Kernel PCA). We also compare results using 2D and 3D CNN methods. The diffusion maps method has an average accuracy of 98% for the PPMI and 90% for the KCGMH-TW dataset with twenty-five fold cross-validation results. It outperforms the other three methods concerning the overall accuracy and the robustness in the training and testing samples.
