description: In a recent paper, Liu et al. [``Lift and drag in three-dimensional steady viscous and compressible flow'', Phys. Fluids 29, 116105 (2017)] obtained a universal theory for the aerodynamic force on a body in three-dimensional steady flow, effective from incompressible all the way to supersonic regimes. In this theory, the total aerodynamic force can be determined solely with the vorticity distribution on a single wake plane locating in the steady linear far field. Despite the vital importance of this result, its validity and performance in practice has not been investigated yet. In this paper, we performed Reynolds-averaged Navier-Stokes simulations of subsonic, transonic, and supersonic flows over a three-dimensional wing. The aerodynamic forces obtained from the universal force theory are compared with that from the standard wall-stress integrals. The agreement between these two formulas confirms for the first time the validity of the theory in three-dimensional steady viscous and compressible flow. The good performance of the universal formula is mainly due to the fact that the turbulent viscosity in the wake is much larger than the molecular viscosity therein, which can reduce significantly the distance of the steady linear far field from the body. To further confirm the correctness of the theory, comparisons are made for the flow structures on the wake plane obtained from the analytical results and numerical simulations. The underlying physics relevant to the universality of the theory is explained by identifying different sources of vorticity in the wake.

description: The goal of the Financial Independence policy conference held on September 16 and 17, 2024 in Washington, D.C. was to bring together experts from the asset and income fields to share theory, evidence, and best practices as part of an effort to work toward development of a new social contract capable of ending poverty. It was divided into four sessions. Sessions one and two focused on Children’s Savings Accounts and Baby Bonds as promising asset building policy proposals for solving the wealth inequality aspect of poverty. The third session focused on Unconditional Cash Transfers, the Child Tax Credit, and Child Allowances as promising income policy proposals for solving the income inequality aspect of poverty. Because poverty has both an income and asset component, the final session discussed why a core component of a new social contract meant to end poverty must include the combining of these strategies. This policy brief is part of the Baby Bonds’ session.
description: The Baby Bonds Task Force, under the leadership of the Massachusetts Office of Economic Empowerment, played an instrumental role in shaping the Baby Bonds proposal. Their findings underscore the necessity of targeted financial investments to close racial wealth gaps, providing data to illustrate how Baby Bonds could drastically improve the financial outlook for low-income families across the state. The 2023 Massachusetts Baby Bonds proposal is framed as a key tool for addressing the racial wealth gap by offering long- term wealth-building opportunities for children born into low- income families.
Excitation dynamics in chain-mapped environments

description: The chain mapping of structured environments is a most powerful tool for the simulation of open quantum system dynamics. Once the environmental bosonic or fermionic degrees of freedom are unitarily rearranged into a one dimensional structure, the full power of Density Matrix Renormalization Group (DMRG) can be exploited. Beside resulting in efficient and numerically exact simulations of open quantum systems dynamics, chain mapping provides an unique perspective on the environment: the interaction between the system and the environment creates perturbations that travel along the one dimensional environment at a finite speed, thus providing a natural notion of light-, or causal-, cone. In this work we investigate the transport of excitations in a chain-mapped bosonic environment. In particular, we explore the relation between the environmental spectral density shape, parameters and temperature, and the dynamics of excitations along the corresponding linear chains of quantum harmonic oscillators. Our analysis unveils fundamental features of the environment evolution, such as localization, percolation and the onset of stationary currents.

description: Coherent Control techniques are computationally applied to cold (1mK < T < 1 K) and ultracold (T < 1 microK) Ne*(3s,3P2) + Ar(1S0) collisions. We show that by using various initial superpositions of the Ne*(3s,3P2) M = {-2,-1,0,1,2} Zeeman sub-levels it is possible to reduce the Penning Ionization (PI) and Associative Ionization (AI) cross sections by as much as four orders of magnitude. It is also possible to drastically change the ratio of these two processes. The results are based on combining, within the "Rotating Atom Approximation", empirical and ab-initio ionization-widths.

Hospital social workers’ appraisal of, reaction to, and coping with a critical incident in their work environment: a descriptive study
Creators: name: Plante, Rodney S.
Publisher: name: University of British Columbia
Year: 2009

description: The intensity and emotional demands of the health care environment place exceptionally high performance expectations and stress on hospital social workers. Critical Incident Stress (CIS), a specific type of stress associated with dramatic, emotionally overwhelming situations, known as Critical Incidents (CIs), produce several emotional and physical reactions that can threaten the well-being of the hospital social worker. CIS, as experienced by hospital social workers, is absent from the literature and not well understood. The purpose of this study was to describe how hospital social workers appraised, reacted to, and coped with CIs in their work environment. Lazarus and Folkman's (1984) theoretical framework of stress appraisal and coping was used to guide this descriptive study. A sample of 30 hospital social workers was recruited from two Vancouver tertiary care hospitals. Four instruments (Participant Information Sheet, Critical Incident Information Form, Emotional Appraisal Scale, and Ways of Coping Scale) were used to gain knowledge on how hospital social workers appraised, reacted to, and coped with CIs in their work environment. Quantitative data were coded, qualitative data were subjected to content analysis, and descriptive statistics calculated. Data revealed that hospital social workers encountered CIs in their work environment and that the majority of CIs centred on death-related events. The primary traits of events appraised as CIs were novelty, suddenness, and uncertainty. Respondents reacted to the CI with a variety of emotional (anxiety, fear, frustration, worry, anger) and physical reactions (feeling overwhelmed, fatigued, withdrawn, anxious, difficulty with sleeping), and although they experienced some discomfort, these reactions were not debilitating. Most hospital social workers indicated that their personal beliefs had been challenged by the CI and revealed that they were unsure as to what their social work role or function should have been during the event. However, despite this, respondents remained confident and comfortable with the decisions they made. Hospital social workers appeared to cope well with CIs, used a variety of emotion- and problem-focused coping strategies, and reported few negative effects on their professional and/or personal lives. The top four coping strategies utilized by respondents were seeking social support, planful problemsolving, positive reappraisal, and self-control. The implications of the findings for hospital social work administration, social work training and education, hospital social work practice, and future research are discussed.

title: Shell Structures Made of Curved Sandwich Panels: Assessment of the Load‐Bearing Capacity
Creators: name: Grimm, Sören

Publisher: name: Ernst & Sohn, a Wiley brand
Year: 2024

description: Lightweight constructions made of sandwich panels became well established for roof and wall claddings of industrial structures. Due to their good heat insulation, their excellent weight to load ratio and high load‐bearing capacity as well as the economical manufacturing and erection process, sandwich structures are build frequently. Besides the mentioned advantages the linear manufacturing process of sandwich panels usually limits the possible building cubature to rectangular shapes. In an interdisciplinary project, architectural, civil engineering and mechanical engineering institutes of Technische Universität Darmstadt are working on a design concept building shell structures with linear manufactured curved sandwich panels.
 
A preliminary study indicates that arched sandwich beams have a high potential regarding the load‐bearing capacity. The comparison between arched and single span sandwich beams shows that, even for asymmetric loads, resulting stresses in the two‐hinged arches are significantly lower than in the related simply supported single span beams.
 
To verify the results of the numeric study full‐scale tests on curved sandwich panels will be performed. Furthermore, an assessment of the load‐bearing behavior of the panels joints loaded with axial forces is planned. Based on the results further numeric studies will be conducted to investigate the behavior of whole shell structures following the developed design principle by taking into account realistic load cases for exemplary building applications, giving special attention to asymmetrical loads.
 
Moreover, further research regarding the requirements for supporting structures as well as for the connection between the shell structure and the supporting structure is necessary to take into account the high axial forces, which are not common in sandwich structures.

description: Anomalous magnetic properties of the double perovskite ruthenates compound Sr2YRuO6 are reported here. Magnetization measurements as a function of temperature in low magnetic fields show clear evidence for two components of magnetic order (TM1 ~ 32K and TM2 ~ 27K) aligned opposite to each other with respect to the magnetic field direction even though only Ru5+moments can order magnetically in this compound. The second component of the magnetic order at TM2 ~ 27K results only in a magnetization reversal, and not in the negative magnetization when the magnetization is measured in the field cooled (FC) mode. Isothermal magnetization (M-H) measurements show hysteresis with maximum coercivity (Hc) and remnant magnetization (Mr) at T ~ 27 K, corroborating the presence of the two oppositely aligned magnetic moments, each with a ferromagnetic component. The two components of magnetic ordering are further confirmed by the double peak structure in the heat capacity measurements. These anomalous properties have significance to some of the earlier results obtained for the Cu-substituted superconducting Sr2YRu1-xCuxO6 compounds.

description: Artificial Intelligence (AI) and Machine Learning have enormous potential to transform businesses and disrupt entire industry sectors. However, companies wishing to integrate algorithmic decisions into their face multiple challenges: They have to identify use-cases in which artificial intelligence can create value, as well as decisions that can be supported or executed automatically. Furthermore, the organization will need to be transformed to be able to integrate AI based systems into their human work-force. Furthermore, the more technical aspects of the underlying machine learning model have to be discussed in terms of how they impact the various units of a business: Where do the relevant data come from, which constraints have to be considered, how is the quality of the data and the prediction evaluated? The Enterprise AI canvas is designed to bring Data Scientist and business expert together to discuss and define all relevant aspects which need to be clarified in order to integrate AI based systems into a digital enterprise. It consists of two parts where part one focuses on the business view and organizational aspects, whereas part two focuses on the underlying machine learning model and the data it uses.

description: We use the recently proposed Kaluza-Klein (KK) reduction over the time dimension, within an effective field theory (EFT) approach, to calculate the next to leading order (NLO) gravitational spin1-spin2 interaction between two spinning compact objects. It is shown here that to NLO in the spin1-spin2 interaction, the reduced KK action within the stationary approximation is sufficient to describe the gravitational interaction, and that it simplifies calculation substantially. We also find here that the gravito-magnetic vector field defined within the KK decomposition of the metric mostly dominates the mediation of the interaction. Our results coincide with those calculated in the ADM Hamiltonian formalism, and we provide another explanation for the discrepancy with the result previously derived within the EFT approach, thus demonstrating clearly the equivalence of the ADM Hamiltonian formalism and the EFT action approach.

description: In image processing, source detections are inevitably affected by the presence of the geometric boundaries in the images, including the physical boundaries of the CCD, and the boundaries of masked regions due to column defects, bright diffraction spikes, etc.. These boundary conditions make the source detection process not statistically isotropic. It can lead to additive shear bias near the boundaries. We build a phenomenological model to understand the bias, and propose a simple method to effectively eliminate the influence of geometric boundaries on shear measurement. We demonstrate the accuracy and efficiency of this method using both simulations and the z-band imaging data from the third data release of the DECam Legacy Survey.
Ramping it up : mixed ramp-gaussian basis sets
Creators: name: McKemmish, Laura Kelly
Publisher: name: The Australian National University
Year: 2015

description: For decades, all-Gaussian basis sets have dominated molecular quantum chemistry, despite some of their less desirable properties. In particular, gaussian basis functions cannot describe the nuclear-electron cusp and consequently large numbers of high exponents gaussians are present in core basis functions to try to describe the inner core electron distribution adequately. This is despite the fact that core electron distribution changes little in response to changing molecular environments and is not an important contribution to chemical energetics that chemists are generally interested in (reaction energies, ionisation energies, isomerisation energies and so on). The principal reason for the dominance of gaussian basis sets is that accurate evaluation of two-electron integral evaluation in these basis sets is far quicker than for other competing types of basis sets. This thesis seeks to change this. We reintroduce a ramp basis function, which has a non-zero nuclearelectron cusp and can therefore describe the inner core accurately and efficiently. This ramp function has compact support, which greatly reduces the difficulty of two-electron integral evaluation, but means it cannot describe valence electron distributions. Thus, gaussian basis functions are added to describe valence electrons to form a mixed ramp-gaussian basis set. To simplify the development of this new class of basis set, we modify only the core basis function in 6-31G (6-31+G) to produce R-31G (R-31+G). These novel rampified basis sets have very similar chemistry to their parent basis sets in atoms and molecules in Hartree-Fock (HF), density functional theory (DFT) and Moller-Plesset 2 Theory (MP2) calculations. The mixed ramp-gaussian basis sets are vastly better than their parent basis sets at predicting electron density at the nucleus and in fact gives better performance than cc-pVQZ. Faster HF, DFT and MP2 calculations in large molecules would increase the speed of the most common types of computational chemistry calculations in the world. This thesis provides strong evidence that mixed ramp-Gaussian basis sets are a viable way to get these faster calculations without compromising chemical accuracy. A preliminary integral evaluation program, RampItUp, was developed in this thesis that calculates all one- and two-electron ramp-containing integrals for a mixed ramp-Gaussian basis set with S-ramps, sand p-gaussians. With the main caveat that two-electron screening is not performed in either basis set, the Fock build time for R-31+G is faster than in 6-31+G by about 10% for large linear molecules, e.g. fatty acids, with more than 20 heavy atoms. This demonstrates that fast integral evaluation is possible. This thesis provides strong justification for the inclusion of ramp-gaussian basis sets into mainstream quantum chemistry packages to allow the full benefits of these new type of basis sets to be experienced by the field as a whole.
The Bundle Theory Approach to Relational Quantum Mechanics
Creators: name: Oldofredi, Andrea
Publisher: name: arXiv
Year: 2020
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: The present essay provides a new metaphysical interpretation of Relational Quantum Mechanics (RQM) in terms of mereological bundle theory. The essential idea is to claim that a physical system in RQM can be defined as a mereological fusion of properties whose values may vary for different observers. Abandoning the Aristotelian tradition centered on the notion of substance, I claim that RQM embraces an ontology of properties that finds its roots in the heritage of David Hume. To this regard, defining what kind of concrete physical objects populate the world according to RQM, I argue that this theoretical framework can be made compatible with (i) a property-oriented ontology, in which the notion of object can be easily defined, and (ii) moderate structural realism, a philosophical position where relations and relata are both fundamental. Finally, I conclude that under this reading relational quantum mechanics should be included among the full-fledged realist interpretations of quantum theory.

description: This paper examines the factors that influence the success of federal court cases about the Endangered Species Act (ESA). I use logistic regression and empirical analysis to test several models of judicial decision-making on section 4 ESA cases. In this paper, I aggregate literature on judicial decision-making, wilderness as a concept, and the implementation of the ESA and discuss the effects of these separate fields on each other. Next, I evaluate the characteristics of 358 district court cases by building a model using backwards selection from 27 original variables. The variables that are significantly influential in whether an animal is ultimately protected are: what the judge’s ideology is, whether the plaintiff is a group, and whether the animal in question is charismatic. I find that the ESA is both a victim to and the epitome of the broader disagreement among Americans about how we define and treat wilderness. The ESA is incoherent and provides little guidance to its implementing agencies, forcing judges to use their own personal conceptions of wilderness in ESA cases. A national exploration of our relationship with wilderness is necessary to end the ESA’s erratic implementation and confront the effects of judicial policymaking through adversarial legalism on our democratic principles.

description: It is essential for the understanding of stellar structure models of high mass stars to explain why constant stars, non-pulsating chemically peculiar hot Bp stars and pulsating stars co-exist in the slowly pulsating B stars and beta Cephei instability strips. We have conducted a search for magnetic fields in the four Bp stars HD55522, HD105382, HD131120, and HD138769 which previously have been wrongly identified as slowly pulsating B stars. A recent study of these stars using the Doppler Imaging technique revealed that the elements He and Si are inhomogeneously distributed on the stellar surface, causing the periodic variability. Using FORS1 in spectropolarimetric mode at the VLT, we have acquired circular polarisation spectra to test the presence of a magnetic field in these stars. A variable magnetic field is clearly detected in HD55522 and HD105382, but no evidence for the existence of a magnetic field was found in HD131120. The presence of a magnetic field in HD138769 is suggested by one measurement at 3 sigma level. We discuss the occurence of magnetic B stars among the confirmed pulsating B stars and find strong magnetic fields of order kG and oscillations to be mutually exclusive.

description: We study the properties of Lyman-alpha emitters (LAEs) and Lyman-break galaxies (LBGs) at z=3-6 using cosmological SPH simulations. We investigate two simple scenarios for explaining the observed Ly-a and rest-frame UV luminosity functions (LFs) of LAEs: (i) the "escape fraction" scenario, in which the "effective" escape fraction (including the IGM attenuation) of Ly-a photons is f_Lya ~0.1 (0.15) at z=3 (6), and (ii) the "stochastic" scenario, in which the fraction of LAEs that are turned on at z=3 (6) is \Cstoc ~0.07 (0.2) after correcting for the IGM attenuation. Our comparisons with a number of different observations suggest that the stochastic scenario is preferred over the escape fraction scenario. We find that the mean values of stellar mass, metallicity and black hole mass hosted by LAEs are all smaller in the stochastic scenario than in the escape fraction scenario. In our simulations, the galaxy stellar mass function evolves rapidly, as expected in hierarchical structure formation. However, its evolution is largely compensated by a beginning decline in the specific star formation rate, resulting in little evolution of the rest-frame UV LF from z=6 to 3. The rest-frame UV LF of both LAEs and LBGs at z=3 & 6 can be described well by the stochastic scenario provided the extinction is moderate, E(B-V) ~0.15, for both populations, although our simulation might be overpredicting the number of bright LBGs at z=6. We also discuss the correlation function and bias of LAEs. The Ly-a LFs at z=6 in a field-of-view of 0.2 deg^2 show a significantly larger scatter owing to cosmic variance relative to that in a 1 deg^2 field, and the scatter seen in the current observational estimates of the Ly-a LF can be accounted for by cosmic variance.

description: Ιδιαίτερα ενδιαφέρον είναι εκείνο το τμήμα της Διαφορικής Γεωμετρίας που αναφέρεται στη μελέτη προβλημάτων που έχουν "ολικό" χαρακτήρα. ΄Ετσι, στο πλαίσιο της Ευκλείδειας Διαφορικής Γεωμετρίας, μπορούν να μελετηθούν π.χ. οι κλειστές καμπύλες. Ακριβώς αυτό είναι και το θέμα της παρούσας εργασίας. Για λόγους οικονομίας χώρου, θα εξαιρεθούν από τη μελέτη μας οι επίπεδες κλειστές καμπύλες. Ο χώρος, εντός του οποίου θα εργασθούμε, είναι ο Ευκλείδειος χώρος Rn(n 3).Ένα από τα πρώτα σπουδαία συμπεράσματα της θεωρίας των κλειστών καμπυλών του χώρου R3 υπήρξε ένα θεώρημα του W. Fenchel (1929), το οποίο καθόριζε τον αριθμό 2π ως το κατώτερο φράγμα της ολικής καμπυλότητας μιας τέτοιας καμπύλης. Το θεώρημα αυτό απεδείχθη αργότερα και από άλλους μαθηματικούς με διαφορετικούς τρόπους. Με το ίδιο θέμα ασχολήθηκαν και οι Μ.I. Fary (1949) και J.W. Milnor (1950), θεωρώντας κλειστές καμπύλες του χώρου R3 με έναν ή περισσότερους κόμβους. Γενίκευση του θεωρήματος του Fenchel για κλειστές καμπύλες του χώρου Rn (n 3) δόθηκε για πρώτη φορά από τον Κ. Borsuk (1947). Ειδικά οι σφαιρικές κλειστές καμπύλες του χώρου R3 υπήρξαν αντικείμενο μελέτης από τον J.L. Weiner (1974, 1977). Ένα άλλο ενδιαφέρον θέμα της θεωρίας των κλειστών καμπυλών είναι και οι εγκάρσιες (athwart) κλειστές καμπύλες. Οι τελευταίες μελετήθηκαν από τον F.J. Craveiro de Carvalho στη Διδακτορική του Διατριβή (βλ.[9]). Η παραπάνω θεματική αποτελεί το περιεχόμενο της εργασίας αυτής. Eιδικότερα: Στο εισαγωγικό Κεφάλαιο Ι αναφέρονται μερικές βασικές έννοιες της θεωρίας καμπυλών του χώρου R3 (τύποι Frenet, σφαιρικές δείκτριες κλπ.) καθώς και το θεμελιώδες θεώρημα ύπαρξης της θεωρίας καμπυλών. Η ανάπτυξη του θέματος της Διπλωματικής Εργασίας γίνεται στο Κεφάλαιο ΙΙ, το οποίο αποτελείται από οκτώ παραγράφους. Στην πρώτη παράγραφο αποδεικνύεται το θεώρημα του Fenchel, ακολουθώντας την απόδειξη του Η. Liebmann (βλ. π.χ. [36]). Στις παραγράφους 2 και 3 μελετάται η ολική καμπυλότητα μιας κλειστής καμπύλης με έναν ή περισσότερους κόμβους στο χώρο Rn. Στην παράγραφο 4 αποδεικνύεται ότι η ολική στρέψη μιας σφαιρικής κλειστής καμπύλης ισούται με μηδέν. Στην παράγραφο 5 γίνεται μελέτη των κλειστών καμπυλών με σταθερή στρέψη, ενώ στην παράγραφο 6 αναφέρονται ορισμένες ιδιότητες των κλειστών σφαιρικών καμπυλών. Οι εγκάρσιες κλειστές καμπύλες αποτελούν το αντικείμενο της παραγράφου 7. Τέλος, στην παράγραφο 8 αποδεικνύεται μία γενίκευση του θεωρήματος του Fenchel (για κλειστές καμπύλες του χώρου Rn), η οποία οφείλεται στον M. Rochowski (1969). Ε Ε

Comment on "Kosterlitz-Thouless-type caging-uncaging transition in a quasi-one-dimensional hard disk system" [Phys. Rev. Research 2, 033351 (2020)]

description: Huerta et al. [Phys. Rev. Research 2, 033351 (2020)] report a power-law decay of positional order in numerical simulations of hard disks confined within hard parallel walls, which they interpret as a Kosterlitz-Thouless-type caging-uncaging transition. The proposed existence of such a transition in a quasi-one-dimensional (q1D) system, however, contradicts long-held physical expectations. To clarify if the proposed ordering persists in the thermodynamic limit, we introduce an exact transfer matrix approach to expeditiously generate equilibrium configurations for systems of arbitrary size. The power-law decay of positional order is found to extend only over finite distances. We conclude that the numerical simulation results reported are associated with a crossover, and not a proper thermodynamic phase transition.

description: We study the properties of the galaxies hosting the first 19 tidal disruption events (TDEs) detected with the Zwicky Transient Facility (ZTF) within the context of a carefully constructed, representative host galaxy sample. We find that the ZTF sample of TDE hosts is dominated by compact "green valley" galaxies. After we restrict the comparison sample to galaxies with a similar concentration, as measured by Sersic index, we find this green valley over representation is even larger. That is, concentrated red sequence galaxies are not producing TDEs at elevated levels. We present host galaxy spectra which show that E+A galaxies are overrepresented in the ZTF sample by a factor of $\approx$22, which is lower than previous TDE host galaxy studies have found. We find that this overrepresentation can be fully accounted for when taking into account the masses, colors, and Sérsic indices of the ZTF TDE hosts. The combination of both green colors and high Sérsic index of the typical TDE host galaxy could be explained if the TDE rate is temporarily enhanced following a merger that leads to a higher central concentration of stars.

A taxonomic study of seaweeds of North Sulawesi, Indonesia
Creators: name: Thenu, Tania
Publisher: name: University of British Columbia
Year: 2009

description: Biodiversity has become a world issue recognized not only by conservationists but also by politicians and other concerned people. The increased interest in biodiversity has generated a need for more information on species occurrence and distribution, and thus taxonomic information has again become essential. The chance of conserving any biological resource is improved if such a resource is fully identified and named. As basic information, taxonomy provides classification, nomenclature, description and identification aids. This can lead to more effective communication about conservation problems and effective action on how to solve such problems. Above all, species identification is a fundamental prerequisite for most biological studies. Indonesia, the world's largest archipelago, is renowned for its biodiversity. Differences in its geological origin have resulted in a diverse and distinct fauna and flora in different regions. Ecologically, it is more diverse, complex and, in most parts, unknown, than perhaps any other part of the world. More than half of Indonesian territory is sea, and there are thousands of kilometers of coastline. Given the large shoreline, seaweeds are a common component of the marine biota. However, seaweeds of Indonesia as a whole have received little attention and even less is known about their possible biogeographic relationships. This present study deals with seaweeds of North Sulawesi, Indonesia. The main objective of this study was to collect and identify seaweeds of North Sulawesi. The other objective was to place this current information into the context of what is known of the Indonesian seaweeds. In this study, a total of 67 species within 37 genera of seaweeds have been recognized. This total consists of 29 taxa of Chlorophyta, 12 taxa of Phaeophyta and 26 taxa of noncoralline Rhodophyta. This information is compared with those of the Siboga Expedition, the Danish Expedition, the Snellius-ll Expedition and the Buginesia-lll Project. Keys to the genera and/or species, description of each taxon, local distribution and the depth are also included along with some photographs of the habit of species.

description: We demonstrate a voltage-controlled exchange bias effect in CoFeB/MgO/CoFeB magnetic tunnel junctions that is related to the interfacial Fe(Co)Ox formed between the CoFeB electrodes and the MgO barrier. The unique combination of interfacial antiferromagnetism, giant tunneling magnetoresistance, and sharp switching of the perpendicularly-magnetized CoFeB allows sensitive detection of the exchange bias. It is found that the exchange bias field can be isothermally controlled by magnetic fields at low temperatures. More importantly, the exchange bias can also be effectively manipulated by the electric field applied to the MgO barrier due to the voltage-controlled antiferromagnetic anisotropy in this system.
