description: The semiclassical Lifshitz-Kosevich-type description is given for the angular dependence of quantum oscillations with combination frequencies in a multiband quasi-two-dimensional Fermi liquid with a constant number of electrons. The analytical expressions are found for the Dingle, thermal, spin, and amplitude (Yamaji) reduction factors of the novel combination harmonics, where the latter two strongly oscillate with the direction of the field. At the "magic" angles those factors reduce to the purely two-dimensional expressions given earlier. The combination harmonics are suppressed in the presence of the non-quantized ("background") states, and they decay exponentially faster with temperature and/or disorder compared to the standard harmonics, providing an additional tool for electronic structure determination. The theory is applied to Sr$_2$RuO$_4$.

description: This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that financial speculation is poorly significant in modelling returns in commodities futures while macroeconomic factors help explaining returns in commodities futures. Moreover, spillovers between commodities are present and the conditional correlations among commodities are high and time-varying.

description: In this paper, we report our recent findings on the relativistic Weibel instability and its nonlinear saturation by performing numerical simulations of collisionless plasmas. Analysis of the obtained numerical results revealed that the nonlinear phase of the Weibel instability can be described by characteristic phases based on the Weibel filaments' current density in terms of particle and Alfvén limit currents. We also analyzed the relativistic kink instability based on the energy principle in the magnetohydrodynamic (MHD) regime, and found that the Weibel filaments do not suffer from the kink-type instability in the MHD regime up to 1000 $ω_{p,i}^{-1}$. This finding allowed a magnetic field to be sustained by relativistic Weibel instability that was stable enough to be a seed for MHD dynamos.

description: This study expands the Inter-Institutional Gaps (IIGs) framework to conceptualize the legitimacy associated with different types of ecological knowledge (e.g., scientific, traditional and local) used in natural resource governance. We draw on primary qualitative data, and document analysis to examine a case of inland fisheries management in the north-eastern floodplain of Bangladesh. We posit that the pragmatic, moral, cognitive, and regulative legitimacy for different types of ecological knowledge are repeatedly reevaluated by rule-makers and resource users in the process of rule-devising. Results show that inter-institutional gaps may be perpetuated when formal rules do not sufficiently consider traditional and local ecological knowledge. While it is widely proposed that systematically incorporating different knowledge types can better address local-national policy problems, this study underscores that the source of legitimacies for different knowledge types often differs across formal and informal institutional actors. Recognizing the differences is critical to fishers’ resource management.

The high temperature limit of the entropy density is expressed in terms of the solution of the osp(1|2s) version of the Q-system. In particular for fundamental representation case, we also derive a TBA equation from the osp(1|2s) version of the T-system and the quantum transfer matrix method. This TBA equation is identical to the one from the string hypothesis. The central charge is expressed by the Rogers dilogarithmic function, and identified to s.

description: Thermal management strategies based on phase change materials (PCMs) offer promising alternatives to conventional approaches, owing to their ability to absorb transient heat flows by melting. However, the design of PCM heat sinks is challenging due to the nonlinear interactions between heat flow and phase change during melting and solidification. This paper presents the design optimization of PCM heat sinks using a Gaussian Process (GP) method. We show that the GP method offers a significant decrease in computational intensity compared to conventional approaches used for optimization. We apply our method to optimize the design of a PCM-integrated heat sink for a gallium nitride (GaN) device that operates under a pulse train heat profile. Field’s metal-infused copper foam is used as the PCM. We used a reduced order model (ROM) for the PCM-integrated device, which is validated through experimental measurements and finite element simulations. We coupled the ROM with the GP optimizer to determine PCM heat sink design parameters, including geometric dimensions and the composition of the composite PCM, which minimizes both the GaN maximum junction temperature and junction temperature swing. We tested the GP optimizer under various conditions, encompassing GaN device power levels ranging from 1 to 4 W, pulse widths spanning 1 to 10 s, and duty cycles ranging from 10 to 90%. The GP optimizer produced nearly identical results to particle swarm optimization, with a mean absolute error <0.2 °C for optimal thermal performance and a reduction in computational time of 39×. Overall, our design method offers a computationally efficient approach to optimizing PCM-integrated heat sinks for the transient thermal management of electronic devices.

All Hermitian Hamiltonians Have Parity

description: It is shown that if a Hamiltonian $H$ is Hermitian, then there always exists an operator P having the following properties: (i) P is linear and Hermitian; (ii) P commutes with H; (iii) P^2=1; (iv) the nth eigenstate of H is also an eigenstate of P with eigenvalue (-1)^n. Given these properties, it is appropriate to refer to P as the parity operator and to say that H has parity symmetry, even though P may not refer to spatial reflection. Thus, if the Hamiltonian has the form H=p^2+V(x), where V(x) is real (so that H possesses time-reversal symmetry), then it immediately follows that H has PT symmetry. This shows that PT symmetry is a generalization of Hermiticity: All Hermitian Hamiltonians of the form H=p^2+V(x) have PT symmetry, but not all PT-symmetric Hamiltonians of this form are Hermitian.

description: The evolution of ethnological fieldwork methodologies reflects a dynamic interplay between shifting conceptual frameworks and practical engagements with diverse social contexts. Over time, ethnographers have navigated varying approaches to fieldwork, as evidenced by ethnographic accounts and anthropological literature. Initially, the emphasis on the ethnologist's terrain, a hallmark of the discipline, recedes as encounters with the "other" foreground the significance of difference, rationalizing the need for investigation. With the decolonization of colonies and the repatriation of ethnologists, attention pivots towards scrutinizing the nature of interactions forged between the ethnographer and the studied social agents, thereby elevating this relational aspect as a methodological focal point.

This methodological pivot prompts a reevaluation of the ethnologist's positionality and reflexivity in knowledge production, particularly as the social profiles of both ethnographers and their subjects increasingly mirror each other. As ethnographers often hail from urban milieus and are associated with various institutions such as enterprises, associations, and scientific laboratories, their encounters with similar social actors underscore the intricate reflexivity embedded within the discipline. Consequently, the construction of ethnographic knowledge becomes intricately intertwined with the ethnologist's self-awareness and critical reflection on their own socio-cultural situatedness.

This abstract delves into the historical trajectory of ethnological fieldwork methodologies, tracing shifts in emphasis from the terrain to relational dynamics between ethnographers and social agents. By interrogating the methodological singularity arising from post-colonial repatriation and the parallel social profiles shared by ethnographers and their subjects, it illuminates the reflexive dimensions shaping knowledge production in ethnology.

description: Wireless sensor networks (WSN) acts as the backbone of Internet of Things (IoT) technology. In WSN, field sensing and fusion are the most commonly seen problems, which involve collecting and processing of a huge volume of spatial samples in an unknown field to reconstruct the field or extract its features. One of the major concerns is how to reduce the communication overhead and data redundancy with prescribed fusion accuracy. In this paper, an integrated communication and computation framework based on meta-learning is proposed to enable adaptive field sensing and reconstruction. It consists of a stochastic-gradient-descent (SGD) based base-learner used for the field model prediction aiming to minimize the average prediction error, and a reinforcement meta-learner aiming to optimize the sensing decision by simultaneously rewarding the error reduction with samples obtained so far and penalizing the corresponding communication cost. An adaptive sensing algorithm based on the above two-layer meta-learning framework is presented. It actively determines the next most informative sensing location, and thus considerably reduces the spatial samples and yields superior performance and robustness compared with conventional schemes. The convergence behavior of the proposed algorithm is also comprehensively analyzed and simulated. The results reveal that the proposed field sensing algorithm significantly improves the convergence rate.

description: The temperature and magnetic field dependence of the specific heat cp(T,H) in the superconducting mixed state as well as the upper critical field Hc2(T) have been measured for polycrystalline Y_xLu_{1-x}Ni_2B_2C and Y(Ni_{1-y}Pt_y)_2B_2C samples. The linear-in-T electronic specific heat contribution gamma(H)T exhibits significant deviations from the usual linear-in-H law for all x and y the transition metal site (T) resulting in a disorder dependent negative curvature of gamma(H). The deviations from that linear behaviour of our unsubstituted samples are the largest reported so far for any superconductor. The H_c2(T) data point to the quasi-clean limit for (Y,Lu)-substitutions and to a transition to the quasi-dirty limit for (Ni,Pt)-substitutions. The gamma(H) dependence is discussed in the unitary d-wave as well as in the quasi-clean s-wave limits. From a consideration of gamma(H) data only, d-wave pairing cannot be ruled out.

description: We discuss electronic transport through a lateral quantum dot close to the singlet-triplet degeneracy in the case of a single conduction channel per lead. By applying the Numerical Renormalization Group, we obtain rigorous results for the linear conductance and the density of states. A new quantum phase transition of the Kosterlitz-Thouless type is found, with an exponentially small energy scale $T^*$ close to the degeneracy point. Below $T^*$, the conductance is strongly suppressed, corresponding to a universal dip in the density of states. This explains recent transport measurements.

description: The goals of the present study were to describe the development of the first national longitudinal study of collegiate recovery program (CRP) students; provide an updated characterization of CRP students’ demographics, past problem severity, and current recovery-related functioning; and examine the perceived impact of COVID-19 on CRP students’ recovery. Universities and community colleges with CRPs across the United States and Ontario, Canada, were invited to partner on this project. Launched in fall 2020, three cohorts of participants were recruited. All participants who completed the baseline survey (N = 334 from 43 CRPs) were invited to complete follow-up surveys. The sample was composed of mostly undergraduate, White, cisgender women averaging 29 years old at baseline. They reported challenging backgrounds, including high levels of polysubstance use, alcohol/substance problem severity, mental health challenges, and involvement with the criminal legal system. Despite such adversity, they evidenced high levels of recovery-related functioning. Recovery capital and quality of life were high. Students reported an average of nearly four years in recovery, with most having between two and four years of abstinence from their primary substance of choice. COVID-19 represented a substantial source of stress for many, impacting some students’ abstinence and recovery-related functioning. Results generally parallel findings from the only other national study of CRP students conducted a decade ago, providing a much-needed update and novel insights into CRP students. Findings can inform our understanding of the CRP student population and can be used to tailor CRP design and service offerings to students’ backgrounds and needs.

description: We report on progress made in the construction of higher-derivative superinvariants for type-II theories in ten dimensions. The string amplitude calculations required for this analysis exhibit interesting features which have received little attention in the literature so far. We discuss two examples from a forthcoming publication: the construction of the (H_{NS})^2 R^3 terms and the fermionic completion of the εεR^4 terms. We show that a correct answer requires very careful treatment of the chiral splitting theorem, implies unexpected new relations between fermionic correlators, and most interestingly, necessitates the use of worldsheet gravitino zero modes in the string vertex operators. In addition, we discuss the relation of our results to the predictions of the linear scalar superfield of the type-IIB theory and find (and explain) an interesting discrepancy.

description: Future electricity distribution grids will host a considerable share of the renewable energy sources needed for enforcing the energy transition. Demand side management mechanisms play a key role in the integration of such renewable energy resources by exploiting the flexibility of elastic loads, generation or electricity storage technologies. In particular, local energy markets enable households to exchange energy with each other while increasing the amount of renewable energy that is consumed locally. Nevertheless, as most ex-ante mechanisms, local market schedules rely on hour-ahead forecasts whose accuracy may be low. In this paper we cope with forecast errors by proposing a game theory approach to model the interactions among prosumers and distribution system operators for the control of electricity flows in real-time. The presented game has an aggregative equilibrium which can be attained in a semi-distributed manner, driving prosumers towards a final exchange of energy with the grid that benefits both households and operators, favoring the enforcement of prosumers' local market commitments while respecting the constraints defined by the operator. The proposed mechanism requires only one-to-all broadcast of price signals, which do not depend either on the amount of players or their local objective function and constraints, making the approach highly scalable. Its impact on distribution grid quality of supply was evaluated through load flow analysis and realistic load profiles, demonstrating the capacity of the mechanism ensure that voltage deviation and thermal limit constraints are respected.
Dangers of Using Political Preference Functions in Political Economy Analysis: Examples from U.S. Ethanol Policy

description: Rausser and Freebairn (1974) proposed a method for empirically measuring the political power of interest groups competing in real-world political economies. In the first half of the 1990s, staunch criticism of PPF methodology appeared. Von Cramon-Taubadel (1992) obtained counter-intuitive results in PPF simulations using a simple model of EU wheat and barley policy instrument use. Bullock (1994) emphasized that PPF methodology requires that observed policy be Pareto efficient policy, which requires researchers to manipulate the dimensions of their models so that the number of interest groups is exactly one more than the number of policy instruments. He concluded “[PPF methods] need not reveal anything meaningful about interest group political power, and may incorrectly measure the direction of transfers” (Bullock 1994, p. 347). The criticisms of the PPF approach were cogent, published in leading agricultural economics journals, and deserved carefully argued response from anyone wishing to continue publishing PPF research. None came forth, even though many PPF studies appeared since. In the present article we provide a step-by-step demonstration of the potential pitfalls of the PPF approach. For our purpose in this article is to once again critique PPF methodology, but this time in a more methodical and less abstract fashion, in hopes of catching and keeping the attention of the upcoming generation’s agricultural political economists. For concreteness, we have chosen a model of U.S. ethanol policy for our simulations. We build the model so that its economic agents can be aggregated or divided into various groups of different sizes, and its several policy instruments can be included or excluded from the model. In these ways, our model is flexible enough for us to use it to illustrate the various issues of model dimension that confront the potential PPF modeler.

description: The polarization and piezoelectric response of the BiTe$X$ ($X$=Cl, Br, and I) layered tellurohalides are computed from first principles. The results confirm a mixed ionic-covalent character of the bonding, and demonstrate that the internal structure within each triple layer is only weakly affected by the external stress, while the changes in the charge distribution with stress produce a substantial negative piezoelectric response. This suggests a new mechanism for negative piezoelectric response that should remain robust even in ultra-thin film form in this class of materials.

description: This paper presents ongoing results of the EU project PEGASUS (Public Perception of Genetically modified Animals – Science, Utility and Society, 7th FP).The overall objective is to provide support for future policy regarding the development, implementation and commercialisation of genetically modified (GM) animals, both terrestrial and aquatic, together with the foods and pharmaceutical products derived from them. Food products derived from GM animals have not yet entered the market. Nonetheless, the ongoing discussion about GM crops and the recently initiated discussions about the safety and ethics of foods and pharmaceutical products derived from cloned animals have set the stage for the socio-economical issues that will surround the introduction of GM animals in the food and pharmaceutical chains. This papers shows the economic and governance pros and cons of GM applications in the animal and pharmaceutical chains, as well as the factors affecting their adoption. Public and producers acceptance, technical improvements and public policies are considered as the main factors affecting the application of GM animals techniques in livestock and pharmaceutical chains.

description: The purpose is to investigate: 1) how many journal titles are both in LOCKSS and in Portico? 2) what is the relationship of small publishers to LOCKSS/CLOCKSS and Portico? 2) what is the relationship of large publishers to LOCKSS/CLOCKSS and Portico? The article describes describes how data from Portico, LOCKSS, and CLOCKSS was cleaned and analyzed using Perl programs to discover duplications. The findings show a significant overlap among the archiving systems. It also shows that Portico has no bias against small publishers and that large publishers are as willing to choose the LOCKSS software as to choose Portico. LOCKSS does, however, archive many more small and arguably endangered publishers and may be the only economically viable choice for them. The push for greater transparency has made more and more data available. Both LOCKSS and Portico deserve commendation for providing the detailed lists of titles and publishers on which this article was based. Such data gives the library community an opportunity to build decisions about the long term digital future on firm and verifiable ground.
ARDC's project impact tracking requirements for National Data Assets projects

Subjects: project impact tracking

description: This presentation was part of an “Orientation to ARDC services and expertise” series, specifically aimed at people involved in one of the ARDC National Data Assets co-investment projects commencing early 2021. ARDC’s National Data Assets portfolio aims to support the development of research data assets and infrastructure to produce reliable high quality research, improve efficiency through greater sharing of resources, catalyse data innovation through data science, and enhance research translation to produce benefits for communities beyond the research sector. To ensure that these strategic goals are achieved, the ARDC requires all National Data Assets projects to plan, implement and report on research outcomes and impact from ARDC invested activities. This session explained ARDC’s project impact tracking requirements for National Data Assets projects. A video recording of this session can also be found on ARDC's YouTube channel: https://youtu.be/zPJ0RvwV2wk
Bose-Einstein Condensates with Large Number of Vortices
Creators: name: Ho, Tin-Lun
Publisher: name: arXiv
Year: 2001
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We show that as the number of vortices in a three dimensional Bose-Einstein Condensate increases, the system reaches a "quantum Hall" regime where the density profile is a Gaussian in the xy-plane and an inverted parabolic profile along z. The angular momentum of the system increases as the vortex lattice shrinks. However, Coriolis force prevents the unit cell of the vortex lattice from shrinking beyond a minimum size. Although the recent MIT experiment is not exactly in the quantum Hall regime, it is close enough for the present results to be used as a guide. The quantum Hall regime can be easily reached by moderate changes of the current experimental parameters.

description: This current Sector-Wide Circularity Assessment report provides contextual information on the four different CityLoops cities and their biomass sectors under study. It then illustrates how circular these sectors are through circularity indicators and a Sankey diagram. Finally, it analyses and interprets the results, presents the limitations of the data used and offers recommendations on how to make this sector more circular. The assessment was carried out by the cities themselves after receiving extensive training on data collection and data processing. Numerous additional insights can be found in the individual Data Hubs of each city.
Multi-criteria analysis for the impact assessment of food safety policies: The case of EU regulation on dietary arsenic

description: Developments in knowledge concerning the toxicology and occurrence of dietary arsenic suggest that levels of exposure in some groups of the population within the EU are a cause for concern. This applies also in the case of individual Member States where local regulatory limits exist. The situation is such that some foods on the market are already the subject of consumer advice provided by government agencies. In the light of these considerations, some have suggested that Member States’ legislation concerning arsenic in foods should be modified and harmonised to reflect such developments. An evaluation of alternative policy initiatives is considered in this work. It employed a computer-based, fuzzy multi-criteria impact assessment tool for the identification of the preferable policy option. Such a tool, named ‘Scryer’, includes a rigorously structured qualitative assessment of each type of impact (e.g. public health, costs for businesses, costs for public authorities) for each policy option, a feasibility filter which considers the opportunity to undertake a quantitative estimation for any type of impact, and the comparison of policy options through a fuzzy multi-criteria approach. The transparency of the tool allows also for a weighting of the impacts. Three policy options concerning regulation of arsenic were evaluated: (1) the status quo option, reflecting the current situation, where levels of arsenic in drinking and mineral waters are governed by EU-wide legislation and that of foods is determined at a Member State level; (2) statutory controls, resulting in the introduction of maximum residue limits for arsenic in foods; and (3) voluntary standards, where the adoption of a policy of self-regulation is expected to reduce levels of inorganic arsenic in the food supply. Application of the Scryer tool suggests that the preferable policy option would be to replace the status quo with legally enforceable (lower) limits at the EU-wide level, and that voluntary limits would be the least risky choice.
Fractional Exclusion Statistics as an Occupancy Process

description: We show the possibility of describing fractional exclusion statistics (FES) as an occupancy process with global and \textit{local} exclusion constraints. More specifically, using combinatorial identities, we show that FES can be viewed as "ball-in-box" models with appropriate weighting on the set of occupancy configurations (merely represented by a partition of the total number of particles). As a consequence, the following exact statement of the generalized Pauli principle is derived: for an $N$-particles system exhibiting FES of extended parameter \mbox{$g=q/r$} ($q$ and $r$ are co-prime integers such that $0 < q \leq r$), (1)~the allowed occupation number of a state is less than or equal to $r-q+1$ and \emph{not} to $1/g$ whenever $q\neq 1$ and (2)~the global occupancy shape is admissible if the number of states occupied by at least two particles is less than or equal to $(N-1)/r$ ($N \equiv 1 \mod r$). These counting rules allow distinguishing infinitely many families of FES systems depending on the parameter $g$ and the size $N$.

description: This article has two purposes. One is to summarize the elements of the Cornell-Yale digitization model in a way that would be useful to other institutions planning to follow their effort. The people involved with the Cornell and Yale projects have done an exceptional job in documenting their work. They have been the Lewis and Clarks of the digitization process. But because they were the first to explore this unkown territory, not every facet of their experience applies to those who follow the path they blazed. It is necessary to see which parts of their experience are applicable to a large state university like Michigan State University (MSU). The other purpose of this article is to show how MSU‘s experience has expanded the Cornell-Yale model. In this MSU is following their tradition of documenting features that could be useful and relevant to to others.
