description: This study investigates the implications of replacing current commodity programs for seven major U.S. field crops with programs styled after the Western Grain Stabilization Program (WGSP) found in Canada. These commodities are: barley, corn, cotton, rice, sorghum, soybeans, and wheat. Given the same external stimuli, computer model simulations to the year 1990 compare possible future producer net receipts for the above crops under three policy options: a continuation of present commodity programs, their elimination, and their elimination and replacement with a WGS-like program. Important points concerning each WGS-like program fund account and associated Government program costs are highlighted.

description: We perform a search for transiting planets in the NASA K2 observations of the globular cluster (GC) M4. This search is sensitive to larger orbital periods ($P\lesssim 35$ days, compared to the previous best of $P\lesssim 16$ days) and, at the shortest periods, smaller planet radii (R$_p\gtrsim0.3$ R$_J$, compared to the previous best of R$_p\gtrsim0.8$ R$_J$) than any previous search for GC planets. Seven planet candidates are presented. An analysis of the systematic noise in our data shows that most, if not all, of these candidates are likely false alarms. We calculate planet occurrence rates assuming our highest significance candidate is a planet and occurrence rate upper limits assuming no detections. We calculate 3$σ$ occurrence rate upper limits of 6.1\% for 0.71-2 R$_J$ planets with 1-36 day periods and 16\% for 0.36-0.71 R$_J$ planets with 1-10 day periods. The occurrence rates from Kepler, TESS, and RV studies of field stars are consistent with both a non-detection of a planet and detection of a single hot Jupiter in our data. Comparing to previous studies of GCs, we are unable to place a more stringent constraint than Gilliland et al. 2000 for the radius-period range they were sensitive to, but do place tighter constraints than both Weldrake et al. 2008 and Nascimbeni et al. 2012 for the large-radius regimes to which they were sensitive.

description: Numerous traditional assessments have been developed to determine suitability of US military recruits for cyber careers. Cyber career field managers expressed a concern there may be well-qualified candidates that lack cyber knowledge, and therefore are not identified with knowledge-based tests. Technological advances such as serious gaming may provide opportunities to assess constructs traditional methods do not effectively measure. The purpose of this effort was to identify potential gains in validity that could be achieved beyond traditional methods through the use of serious games for several cyber jobs (both for enlisted and officer positions). Throughout this phase of research, an extensive literature review of military and civilian assessments targeted cyber occupations. Then, military subject matter experts in these career fields provided input and guidance (e.g., focus on aptitudes and traits as knowledge and skill are rapidly outdated). A gap analysis between all measures of such constructs identified a short list of candidates for measurement in a serious game. A survey of 800 airmen in the 1N4X1A, 3D1X2 and 17DEX/SX career fields was conducted; 290 respondents identified six constructs to be the focus for serious game assessment. The game was developed, and constructs validated on a sample chosen to model Air Force enlisted recruits. Additional psychometric data from enlistees and cyber trainees will be gathered once COVID-19 restrictions are lifted.

description: Deep-learning methods have shown promising performance for low-dose computed tomography (LDCT) reconstruction. However, supervised methods face the problem of lacking labeled data in clinical scenarios, and the CNN-based unsupervised denoising methods would cause excessive smoothing in the reconstructed image. Recently, the normalizing flows (NFs) based methods have shown advantages in producing detail-rich images and avoiding over-smoothing, however, there are still issues: (1) Although the alternating optimization in the data and latent space can well utilize the regularization and generation capabilities of NFs, the current two-way transformation strategy of noisy images and latent variables would cause detail loss and secondary artifacts; and (2) Training NFs on high-resolution CT images is hard due to huge computation. Though using conditional normalizing flows (CNFs) to learn conditional probability can reduce the computational burden, current methods require labeled data for conditionalization, and the unsupervised CNFs-based LDCT reconstruction remains a problem. To tackle these problems, we propose a novel CNFs-based unsupervised LDCT iterative reconstruction algorithm. It employs strict one-way transformation when performing alternating optimization in the dual spaces, thus effectively avoiding the problems of detail loss and secondary artifacts. By proposing a novel unsupervised conditionalization strategy, we train CNFs on high-resolution CT images, thus achieving fast and high-quality unsupervised reconstruction. Experiments on different datasets suggest that the performance of the proposed algorithm could surpass some state-of-the-art unsupervised and even supervised methods.

description: This paper examines three farm labor issues: How mechanization affects the demand for farm labor; the probable effects of immigration reform on the supply of farm workers; and the effects of 10 years of collective bargaining on the farm labor market. The evidence suggests that mechanization, immigration reform, and collective bargaining have had or will have fewer effects on the farm labor market than is often assumed. However, the farm labor market is vulnerable to future shocks if it remains isolated from nonfarm labor markets.

description: Given the demanding nature of its mission, the collective units of the Army, not just individual Soldiers, need to be able to withstand and adapt to a wide range of challenges. Therefore, it is important to be able to effectively assess resilience at the team-level and to understand the factors that can enable or diminish it. This article describes the development of a construct valid and psychometrically-sound measure of team resilience – the Team Resilience Scale (TRS). A theoretical framework of team resilience and related constructs is introduced. We then summarize the procedures for developing the TRS and related constructs, providing evidence of the content validity of the TRS. Finally, we assess the psychometric soundness and construct validity of the TRS in two Army field studies. Our analyses support the convergent validity of items and indicate that the measure can be used to examine three first-order dimensions of resilience (i.e., physical, affective, and cognitive) or as a single overall resilience composite. Results show the TRS was positively related to team performance in both samples and it co-varied with stressors and team actions. Practical recommendations for use of the measure and suggestions for future research are offered.
The Fragility of High-pT Hadron Spectra as a Hard Probe

description: We study the suppression of high-pT hadron spectra in nuclear collisions, supplementing the perturbative QCD factorized formalism with radiative parton energy loss. We find that the nuclear modification factor which quantifies the degree of suppression, is almost pT-independent both for RHIC (in agreement with data) and for the LHC. This is a consequence of the shape of the partonic pT-spectrum in elementary collisions which implies that for the same value of the nuclear modification factor at higher pT, an increasingly smaller fraction of parton energy loss is needed. When the values of the time-averaged transport coefficient exceed 5 GeV^2/fm, the nuclear modification factor gradually loses its sensitivity to the corresponding produced energy density. This is due to particle production in the outer corona of the medium, which remains almost unsuppressed even for extreme densities. Thus, even for the highest experimentally accessible transverse momentum at the LHC and in contrast to jets, the measurement of leading partons via leading hadrons is not a penetrating probe of the dense matter, but a rather fragile probe which fragments for the opacities reached below the skin of the medium. Relating the transport coefficient to the energy density produced in the collision region, we find and discuss a phenomenon reminiscent of the opacity problem of elliptic flow: namely, the interaction of the hard parent parton with the medium appears to be much stronger than that expected for perturbative interactions of the hard parton with an ideal quark gluon plasma.

description: Variations of a result by Dybvig and Ross provide necessary conditions for the FSD, SSD and TSO efficiency of enterprise mixtures. Several of their perfect market portfolio problem results are adapted to the enterprise mixture problem. The results imply that the sets of enterprise mixtures which satisfy the necessary conditions for FSD, SSD and TSO efficiency are unions of finite numbers of convex subsets. Linear programming can be used to determine whether a particular mixture and the (appropriately defined) convex subset to which it belongs satisfy these conditions. These ideas are illustrated by applying them to a simple example.

description: We investigate dissipative dynamical systems under the influence of an external driving with two or more frequencies. Our main quantities of interest are long-time averages of expectation values which turn out to exhibit universal features. In particular, resonance peaks in the vicinity of commensurable frequencies possess a generic enveloping function whose width is inversely proportional to the averaging time. While the universal features can be derived analytically, the transition from the specific short-time behavior to the long-time limit is illustrated for the examples of a classical random walk and a dissipative two-level system both with biharmonic driving. In these models, the dependence of the time-averaged response on the relative phase between the two driving frequencies changes with increasing integration time. For short times, it exhibits the $2π$ periodicity of the dynamic equations, while in the long-time limit, the period becomes a fraction of this value.

title: Going global: Arabian palaeoclimate and human evolution
Creators: name: Nicholson, Samuel Luke
Publisher: name: University of Reading
Year: 2020

description: The vast Arabian deserts sit at a crucial interface between Europe and sub-Saharan Africa 
and acts as a geographical barrier between Afrotropical and Eurasian fauna. However, 
punctuated increases of rainfall throughout the Pleistocene created “green” deserts that 
are increasingly related to mammalian dispersals. These “windows of opportunity” were 
crucial for occupation and dispersal of hominin species and acted as important 
steppingstones on the way to the global colonisation of Homo sapiens. Despite a growing
body of palaeoclimate information from marine sediment cores and relict palaeolake 
deposits, there remain significant gaps in important palaeoclimatological questions. For 
example, what was the precise timing, duration and frequency of wet events? What 
precipitation regime delivered precipitation across Arabia? How did precipitation vary 
within and between pluvial periods? What sorts of environments flourished with 
increased precipitation? Not only are these pertinent questions for accurately 
characterising past climates and environments but answering these can identify 
favourable hominin dispersal windows throughout the Pleistocene. 
To elucidate these issues, this thesis aimed to generate new speleothem-based 
palaeoclimate records from Mukalla (Yemen), Hoti (Oman), Broken-Leg, Star and 
Surprise (Saudi Arabia) Caves. South Arabian Humid Periods (SAHPs) were identified 
by U-Pb and 230Th age determinations of stalagmite growth from Mukalla and Hoti Cave.
These SAHPs were a result of African and Indian Summer Monsoon incursions during 
insolation maxima within peak interglacial periods and warm substages up to 1.1 million 
years ago, as identified by fluid inclusion water δD and δ18O and calcite δ18O
measurements. This increased annual precipitation to >300 mm yr-1 and allowed C4
vegetation to flourish, as determined by calcite δ13C measurements. Identification of sub-annual cycles of δ13C and δ18O indicates environments were highly seasonal, 
characterised by a “wetter” summer and “drier” winter. Additional U-Pb and 230Th dating 
of stalagmites from Broken-Leg, Star and Surprise Cave reflect these findings, indicating 
that wet periods occurred during warm periods of the Pliocene and Early-Pleistocene,
Together, this information shows that Saharo-Arabian palaeoenvironmental fluctuation –
governed by monsoon variability – provided frequent opportunities for hominin 
occupation of Arabia and dispersal throughout the Plio-Pleistocene.

We present results on the properties of N=1/2 supersymmetric theories of chiral superfields in deformed superspace, taking the Wess-Zumino model as the prototype. We prove new (non)renormalization theorems: the F-term is radiatively corrected and becomes indistinguishable from the D-term, while the Fbar-term is not renormalized. Supersymmetric vacua are critical points of the antiholomorphic superpotential. The vacuum energy is zero to all orders in perturbation theory. We illustrate these results with several examples.

description: The markets for many processed fruits and vegetables are characterized by few processors and by market control programs or bargaining organizations on the supply side. Under such conditions, farm level demand functions may not be uniquely specified. This paper develops an approach to econometric estimation of farm pries when there is bargaining, with an application to the cling peach industry. For prediction purposes, the model turns out to be the same as would be obtained if the industry were misspecified to be perfectly competitive. However, proper specification may be important if the results are used for policy analysis.

description: We investigate the holographic p-wave superfluid in the background metric of the AdS soliton with $RF^{2}$ corrections. Two models, namely, the Maxwell complex vector field model and Yang-Mills theory, are studied in the above context by employing the Sturm-Liouville approach as well as the shooting method. When turning on the spatial components of the gauge field, one observes that, in the probe limit, the inclusion of $RF^{2}$ corrections hinders the superfluid phase transition. On the other hand, however, in the absence of the superfluid velocity, it is found that the $RF^2$ corrections lead to distinct effects for the two models. Regardless of either the $RF^2$ correction or the spatial component of the gauge field, the phase transition of the system is observed to be always of the second order. Moreover, a linear relationship between the charge density and chemical potential is largely established near the critical point in both holographic superfluid models.

description: We present a spectroscopic analysis of two galaxy clusters out to ~4Mpc at z~0.2. The two clusters VMF73 and VMF74 identified by Vikhlinin et al. (1998) were observed with MOSCA at the Calar Alto 3.5m telescope. Both clusters lie in the ROSAT PSPC field R285 and were selected from the X-ray Dark Cluster Survey (Gilbank et al. 2004) that provides optical V- and I-band data. VMF73 and VMF74 are located at respective redshifts of z=0.25 and z=0.18 with velocity dispersions of 671 km/s and 442 km/s, respectively. The spectroscopic observations reach out to ~2.5 virial radii. Line strength measurements of the emission lines H_alpha and [OII]3727 are used to assess the star formation activity of cluster galaxies which show radial and density dependences. The mean and median of both line strength distributions as well as the fraction of star forming galaxies increase with increasing clustercentric distance and decreasing local galaxy density. Except for two galaxies with strong H_alpha and [OII] emission, all of the cluster galaxies are normal star forming or passive galaxies. Our results are consistent with other studies that show the truncation in star formation occurs far from the cluster centre.

description: The manifestation of point sources in the upcoming PLANCK maps is a direct reflection of the properties of the pixelized antenna beam shape for each frequency, which is related to the scan strategy, pointing accuracy, noise properties and map-making algorithm. In this paper we firstly compare analytically two filters for the PLANCK point source extraction, namely, the adaptive top-hat filter (ATHF), the theoretically-optimal filter (TOF). Our analyses are based on the premise that the experiment parameters the TOF assume and require are already known: the CMB and noise power spectrum and a circular Gaussian beam shape and size, whereas the ATHF does not need any a priori knowledge. The analyses show that the TOF is optimal in terms of the gain after the parameter inputs. We simulate the PLANCK HFI 100 GHz channel with elliptical beam in rotation to test the efficiency of the TOF and the ATHF. We also apply the ATHF on the WMAP Q-band map and the derived map (the foreground-cleaned map by Tegmark, de Oliveira Costa & Hamilton) from the WMAP 1-year data. The uncertainties on the angular power spectrum will hamper the efficiency of the TOF. To tackle the real situations for the PLANCK point source extraction, most importantly, the elliptical beam shape with slow precession and change of the ellipticity ratio due to possible mirror degradation effect, the ATHF is computationally efficient and well suited for the construction of the PLANCK Early Release Compact Source Catalogue.

We determined the complete set of orbital parameters using the toolkit RadVel by analyzing the observed radial velocity curves. To study the properties of the five systems, we also analyzed the intermediate resolution spectra (R = 20,000) observed with the TIGRE telescope and determined the stellar parameters of the primary stars using the toolkit iSpec. With Gaia Early Data Release 3 parallaxes, a correction for interstellar extinction using the 3D dust map, and bolometric corrections, we placed the stars in the Hertzsprung-Russell diagram and compared the positions with stellar evolution tracks calculated with the Eggleton code to determine the masses and ages of the primary stars. They have all evolved to the giant phase. Finally, we were able to determine the masses of the secondary stars and to estimate the orbital inclinations i of the binary systems.

description: Organic producers in California were surveyed by the author and the Organic Market News and Information Service (OMNIS) to determine: 1) the size of the industry, 2) the commodities grown, 3) acreage under organic cultivation and, 4) growers' perceptions of the production and marketing obstacles limiting expansion. The California organic industry has grown significantly in the 1980s and now is estimated to consist of approximately 900 growers with wholesale sales of about $50 million dollars. Thirty six percent of the respondents farmed on a mixed acreage basis, and the average respondent farmed 38 acres organically with an average farm size of 58 acres. Total California organic area harvested is estimated to be 30,000 acres, with fruits representing about 61 percent of this, and vegetables and nuts each about 13 percent of the total, respectively. Just as for conventional growers, the most important marketing channel for organic producers is sales to wholesalers. However, sales directly to consumers represent twenty one percent of the total volume for organic producers relative to one percent for conventional growers. Organic producers perceive that demand side factors, such as lack of consumer awareness of the benefits of organic products, are the principal constraints to market expansion. In contrast, handlers view limited supply and lack of consistency in quality and pack as the key obstacles impeding expansion.

description: In this work we investigate the matrix elements of the energy-momentum tensor for massless on-shell states in four-dimensional unitary, local, and Poincaré covariant quantum field theories. We demonstrate that these matrix elements can be parametrised in terms of covariant multipoles of the Lorentz generators, and that this gives rise to a form factor decomposition in which the helicity dependence of the states is factorised. Using this decomposition we go on to explore some of the consequences for conformal field theories, deriving the explicit analytic conditions imposed by conformal symmetry, and using examples to illustrate that they uniquely fix the form of the matrix elements. We also provide new insights into the constraints imposed by the existence of massless particles, showing in particular that massless free theories are necessarily conformal.

From comparison between HEA-type and conventional RE123 samples, we found that the mixing entropy at the rare earth site does not affect Tc and critical current density (Jc) of the RE123 samples. For all the examined samples, orthorhombicity was found to be an essential parameter for Tc and Jc. In the regime near orthorhombic-tetragonal boundary, Jc for the HEA-type sample was larger than that of conventional-type samples, which suggests that HEA-type RE123 may be useful to improve Jc in the structure with low orthorhombicity.

description: The X-ray spectrum of the late-type M-dwarf binary AT Mic (dM4.5e+dM4.5e) is observed in the wavelength range 1 - 40 Angstrom by means of rgs and epic-mos on board XMM-Newton. During the exposure a flare occured. We have performed a 3-temperature fit and a DEM-modeling to the flaring and quiescent part of the spectrum. We report the coronal temperature distribution, emission measures, and abundances of the flaring and quiescent state of this bright X-ray source. The temperature range stretches from about 1 to 60 MK. The total volume emission measure in this temperature interval is ~12.2*10^51 cm^-3 for the quiescent state and ~19.5*10^51 cm^-3 for the flare state. This difference is due to the contribution of the hot temperature component. The high-resolution spectrum of AT Mic, obtained by rgs, is dominated by the H- and He-like transitions of C, N, O, and Ne and by Fe XVII lines, produced by the plasma with temperatures from 1 to 10 MK. The epic-mos spectrum below 10 Angstrom shows H- and He-like Ne, Si and the iron K-shell transitions. They are produced by the hot component (30 MK). The iron K-shell is more prominent in the flare state. The abundance pattern in the quiescent state of AT Mic shows the depletion of low-FIP elements relative to high-FIP elements, indicating the presence of an I(nverse)FIP effect in this active star. In the flare state, however, some flattening of this IFIP effect is present.

description: Using spectroscopic data presented in Magrini et al. (2003), we have analyzed with the photoionization code CLOUDY 94.00 (Ferland et al. 1998) 11 Planetary Nebulae belonging to the spiral galaxy M 33. Central star temperatures and nebular parameters have been determined. In particular the chemical abundances of He/H, O/H, N/H, Ar/H, and S/H have been measured and compared with values obtained via the Ionization Correction Factors (ICFs) method, when available. Chemical abundance relationships have been investigated; in particular, a correlation between N/H and N/O similar to the Galactic one (Henry 1989), and a feeble anti-correlation between O/H and N/O have been found. A gradient in O/H across the disc of M~33 is indicatively consistent with the one found from HII regions in this galaxy (Vilchez et al 1988). Further studies in the more external parts of M~33 are however needed to ascertain this point. The present result shows that oxygen and helium abundances (with lower accuracy also nitrogen, argon and sulphur) can be actually estimated from the brightest PNe of a galaxy, even if the electron temperature cannot be measured. We also found that the oxygen abundance is quite independent of the absolute magnitude of the PN and consequently the brightest PNe are representative of the whole PN population. This represents an important tool to measure the metallicity of galaxies at the time of the formation of PNe progenitors.

description: Measurement invariance of psychological test batteries is an essential quality criterion when the test batteries are administered in different cultural and language contexts. The purpose of this study was to examine to what extent measurement model fit and measurement invariance across the two largest language groups in Switzerland (i.e., German and French speakers) can be assumed for selected general mental ability and personality tests used in the Swiss Armed Forces’ cadre selection process. For the model fit and invariance testing, we used Bayesian structural equation modeling (BSEM). Because the sizes of the language group samples were unbalanced, we reran the invariance testing with the subsampling procedure as a robustness check. The results showed that at least partial approximate scalar invariance can be assumed for the constructs. However, comparisons in the full sample and subsamples also showed that certain test items function differently across the language groups. The results are discussed regarding the three following issues: First, we critically discuss the applied criterion and alternative effect size measures for assessing the practical importance of non-invariances. Second, we highlight potential remedies and further testing options, that can be applied, once certain items have been detected to function differently. Third, we discuss alternative modeling and invariance testing approaches to BSEM and outline future research avenues.

description: Motivated by the notion of Lagrangian multiforms, which provide a Lagrangian formulation of integrability, and by results of the authors on the role of covariant Hamiltonian formalism for integrable field theories, we propose the notion of Hamiltonian multiforms for integrable $1+1$-dimensional field theories. They provide the Hamiltonian counterpart of Lagrangian multiforms and encapsulate in a single object an arbitrary number of flows within an integrable hierarchy. For a given hierarchy, taking a Lagrangian multiform as starting point, we provide a systematic construction of a Hamiltonian multiform based on a generalisation of techniques of covariant Hamiltonian field theory. This also produces two other important objects: a symplectic multiform and the related multi-time Poisson bracket. They reduce to a multisymplectic form and the related covariant Poisson bracket if we restrict our attention to a single flow in the hierarchy. Our framework offers an alternative approach to define and derive conservation laws for a hierarchy. We illustrate our results on three examples: the potential Korteweg-de Vries hierarchy, the sine-Gordon hierarchy (in light cone coordinates) and the Ablowitz-Kaup-Newell-Segur hierarchy.

description: In this paper we propose a quiver model of matrix quantum mechanics with 8 supercharges which, on a Higgs branch, deconstructs the worldsheet of Matrix String Theory. This discrete model evades the fermion doubling problem and, in the continuum limit, enhances the number of supersymmetries to sixteen. Our model is motivated by orbifolding the Matrix Model, and the deconstruction {\it ansatz} exhibits a duality between target space compactification and worldsheet deconstruction.

Schools As Community Resources : Recommendations For Supporting Ukrainian Elementary Refugee Students Through Community-Informed Approaches in Winnipeg, Manitoba
Creators: name: Chubenko, Larissa M.
Publisher: name: The University of British Columbia
Year: 2023

description: This paper focuses on the impact of the arrival of Ukrainian refugee students to a Ukrainian-bilingual elementary school located in Winnipeg, Manitoba. These Ukrainian refugee students and their families are in the process of dealing with shared experiences of displacement, loss of community, and resettlement resulting from the recent Russian invasion and war in Ukraine. This school is already in a unique position in supporting refugee students, families and extended community through existing programming involving Ukrainian language, traditions, values, and cultural norms. More specifically, to support these new refugee students requires schools to further establish a Full-Service Community Schools model focusing on community-informed approaches. This paper further provides recommendations for community-informed approaches in schools through implementation of safe and healing school environments, towards empowerment and belonging, as well as examples of community programming and outreach initiatives.

description: We present bound state masses of the self-conjugate and non-self-conjugate mesons in the context of the Schrödinger equation taking into account the relativistic kinematics and the quark spins. We apply the usual interaction by adding the spin dependent correction. The pseudoscalar and vector decay constants of the $B_{c}$ meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local equation with a complete relativistic corrections to a class of three attractive static interaction potentials of the general form $% V(r)=-Ar^{-β}+κr^β+V_{0},$ with $β=1,1/2,~3/4$ which can also be decomposed into scalar and vector parts in the form $% V_{V}(r)=-Ar^{-β}+(1-ε)κr^β$ and $% V_{S}(r)=εκr^β+V_{0};$ where $0\leq ε\leq 1.$ The energy eigenvalues are carried out up to the third order approximation using the shifted large-N-expansion technique.

description: Steam cycles and steam networks are essential for a wide range of thermal power plants and industrial processes. Today steam cycles are used not only in fossil-fired power plants and nuclear power plants but also as heat recovery cycles in gas turbine combined cycles (GTCCs) (Gülen 2019), integrated gasification combined cycles (IGCCs) and polygeneration plants (e.g., coproducing electricity and hydrogen or synthesis fuels) (Elsido et al., 2019). Steam networks and combined heat and power cycles are typically used to optimize the heat integration of a wide range of industrial processes (Luo et al., 2016). Steam cycles are used also in renewable technologies such as concentrated solar power plants (Gonzalo et al., 2019) and large biomass-fired plants (Amec-Foster-Wheeler 2016), as well as waste-to-energy plants (Beiron et al., 2019). While steam cycle components are considered mature technologies, it is important to note that each application features a specific optimal thermodynamic design of the steam cycle (i.e., cycle configuration and steam pressures/temperatures) as well as a tailored control strategy for off-design and ramping (Martelli et al.). While these criteria are well known for fired steam cycles and combined cycle power plants, those for novel energy systems (e.g., Integrated Solar Combined Cycles) are still an object of research and development efforts in both academia and industry [see, e.g., (Elsido et al. 2021), and (Temraz et al., 2021)]. Such efforts are spurred by the need of minimizing fuel consumption and the related environmental emissions. Furthermore, the increased penetration of renewable energy sources in the generation of electrical power recently raises technical and economic challenges for the operation of these plants. Existing thermal power plants have to be retrofitted with optimized components [e.g., warming and pre-warming systems for the steam turbine (Pehle et al., 2020)] and control systems (Casella et al., 2011) to improve their operational flexibility, such as ramping rates and shutdown/start-up times. Consequently, accurate dynamic simulation tools are being developed for developing novel equipment designs, control systems, and start-up procedures (Alobaid et al. 2017).

description: We present a structural and magnetic study on two batches of polycrystalline LiNi$_{0.8}$Mn$_{0.1}$Co$_{0.1}$O$_2$ (commonly known as Li NMC 811), a Ni-rich Li ion battery cathode material, using elemental analysis, X-ray and neutron diffraction, magnetometry, and polarised neutron scattering measurements. We find that the samples, labelled S1 and S2, have the composition Li$_{1-x}$Ni$_{0.9+x-y}$Mn$_y$Co$_{0.1}$O$_2$, with $x = 0.025(2)$, $y = 0.120(2)$ for S1 and $x = 0.002(2)$, $y = 0.094(2)$ for S2, corresponding to different concentrations of magnetic ions and excess Ni$^{2+}$ in the Li$^+$layers. Both samples show a peak in the zero-field cooled (ZFC) dc susceptibility at 8.0(2) K but the temperature at which the ZFC and FC (field-cooled) curves deviate is substantially different: 64(2) K for S1 and 122(2) K for S2. Ac susceptibility measurements show that the transition for S1 shifts with frequency whereas no such shift is observed for S2 within the resolution of our measurements. Our results demonstrate the sample dependence of magnetic properties in Li NMC 811, consistent with previous reports on the parent material LiNiO$_2$. We further establish that a combination of experimental techniques are necessary to accurately determine the chemical composition of next generation battery materials with multiple cations.
