description: Perdita (Pygoperdita) californica (Cresson, 1878)
[♂; California, USA; Perdita californica inopina Timberlake: Holotype: CASC; Inyo Co., California, USA; July 30; 1962]
Perdita californica inhabits the CFP and is a pollen specialist on endemic lilies in the genus Calochortus Pursh (Fowler 2020). We reviewed three specimens, all of which were captured in the Coastal Sage Matorral, one female in Ensenada in June 1952, and two males in San Vicente in May 1938 (CASC). The BBPT collected one male in May 2019 on Cerro Santo Tomás in the Central Desert, one female in May 2020 and four males in June 2020 in the Coastal Sage Matorral. There are also recent observations of this species on iNaturalist that include the floral host (https://www.inaturalist.org/observations?place_id=59163&subview=map&taxon_id=309374). See fig. 63.
Perdita (Pygoperdita) fieldi Timberlake, 1956
[Holotype: USNM; ♀ San Diego Co., California, USA]
Perdita fieldi is distributed in the CFP across California and BC states. We reviewed 32 specimens collected in the Coastal Sage Matorral and Succulent Coastal Matorral in June 1975 and June 1976 (CASC). The BBPT collected nine specimens (6 ♀, 3 ♂) in the Coastal Sage Matorral and the Chaparral during May 2022. See fig. 63.

description: This study explores two hypotheses: that the Asian regional identity is undergoing a period of flux and that Australian national identity is restructuring based on political and economic considerations to becoming more greatly identified with Asia. I use Australia as a case study to examine norms building and the construction of regional architecture in Asia. My findings indicate that the development of an inclusive Asian identity in recent years has allowed Australia to reposition itself as a part of Asia. This process is still ongoing, and the likelihood of Australia's full inclusion is promising.

description: Recently, the emergence of pre-trained models (PTMs) has brought natural language processing (NLP) to a new era. In this survey, we provide a comprehensive review of PTMs for NLP. We first briefly introduce language representation learning and its research progress. Then we systematically categorize existing PTMs based on a taxonomy with four perspectives. Next, we describe how to adapt the knowledge of PTMs to the downstream tasks. Finally, we outline some potential directions of PTMs for future research. This survey is purposed to be a hands-on guide for understanding, using, and developing PTMs for various NLP tasks.

The n-wave procedure and dimensional regularization for the scalar field in a homogeneous isotropic space
Creators: name: Pavlov, Yu. V.
Publisher: name: arXiv
Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We obtain expressions for the vacuum expectations of the energy-momentum tensor of the scalar field with an arbitrary coupling to the curvature in an N-dimensional homogeneous isotropic space for the vacuum determined by diagonalization of the Hamiltonian. We generalize the n-wave procedure to N-dimensional homogeneous isotropic space-time. Using the dimensional regularization, we investigate the geometric structure of the terms subtracted from the vacuum energy-momentum tensor in accordance with the n-wave procedure. We show that the geometric structures of the first three subtractions in the n-wave procedure and in the effective action method coincide. We show that all the subtractions in the n-wave procedure in a four- and five-dimensional homogeneous isotropic spaces correspond to a renormalization of the coupling constants of the bare gravitational Lagrangian.

description: In energy policy, various organizational forms are used. At local and regional levels, energy cooperatives and energy clusters are perfect. Their main advantages are: socialization of the production process, combining social and economic goals and a beneficial effect on the improvement of the natural environment. The aim of the article was to recognize the conditions and state of development of energy cooperatives and energy clusters in Poland and their impact on local development and the entire energy sector as compared with similar activities in Germany. Germany has the largest number of energy cooperatives that operate in the European Union. They lead to the development of civic energy in which the interests of energy producers and consumers are integrated on a large scale. The conducted analysis led to the conclusion that energy cooperatives should have flexible structures resulting from local needs and possibilities, starting from social cooperatives to structures functioning in the form of regional clusters. / Synopsis. W polityce energetycznej wykorzystywane są różne formy organizacyjne. Na szczeblu lokalnym i regionalnym doskonale sprawdzają się spółdzielnie energetyczne i klastry energii. Ich główne zalety to: uspołecznienie procesu wytwórczego, łączenie celów społecznych i ekonomicznych oraz korzystny wpływ na poprawę stanu środowiska naturalnego. Celem artykułu było rozpoznanie warunków i stanu rozwoju spółdzielni energetycznych i klastrów energii w Polsce i ich wpływu na rozwój lokalny oraz całego sektora energetycznego na tle doświadczeń niemieckich. W Niemczech funkcjonuje najwięcej spółdzielni energetycznych w Unii Europejskiej. Prowadzą one do rozwoju na szeroką skalę energetyki obywatelskiej, w której integrują się interesy wytwórców i konsumentów energii. Przeprowadzona analiza pozwoliła wywnioskować, że spółdzielnie energetyczne powinny mieć elastyczne struktury wynikające z lokalnych potrzeb i możliwości, zaczynając od spółdzielni socjalnych do struktur funkcjonujących w formie klastrów o zasięgu regionalnym.

description: We report the experimental setup and overall results of the AARTFAAC wide-field radio survey, which consists of observing the sky within 50$^\circ$ of Zenith, with a bandwidth of 3.2$\,$MHz, at a cadence of 1$\,$s, for 545$\,$h. This yielded nearly 4 million snapshots, two per second, of on average 4800 square degrees and a sensitivity of around 60$\,$Jy. We find two populations of transient events, one originating from PSR$\,$B0950$+$08 and one from strong ionospheric lensing events, as well as a single strong candidate for an extragalactic transient, with a peak flux density of $80\pm30$$\,$Jy and a dispersion measure of $73\pm3\,\mathrm{~pc~cm^{-3}}$, We also set a strong upper limit of 1.1 all-sky per day to the rate of any other populations of fast, bright transients. Lastly, we constrain some previously detected types of transient sources by comparing our detections and limits with other low-frequency radio transient surveys.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study phenomenological constraints on a simple $3-3-1$ model with flavor violating Yukawa couplings. Both triplets Higgs couple to leptons and quarks, which generates flavor violating signals in both lepton and quark sectors. We have shown that this model can allow for large Higgs lepton flavor-violating rate decay $h \rightarrow μτ$ and also can be reached to perfect agreements with other experimental constraints such as $τ\rightarrow μγ$ and $(g-2)_μ$. The contributions of flavor-changing neutral current (FCNC) couplings, Higgs-quark-quark couplings, to the mesons mixing are investigated. Br$(h \rightarrow q q^\prime )$ can be enhanced with keeping from the measurements of meson mixing. The branching ratio for $t \rightarrow q h$ can reach up to $10^{-3}$, but it could be as low as $10^{-8}$.

title: Identification and analysis of a novel scavenger receptor-like protein conserved in Plasmodium species
Creators: name: Eriksdotter Waller, Cecilia Caroline
Publisher: name: The Open University
Year: 2004

description: In October 2002, the complete sequence of the genome of the human malaria parasite Plasmodium falciparum was published. The data showed that as many as 60% of all identified open reading frames were unique to the parasite, with no known homologues in other species. Identification and characterization of novel molecules that may provide targets for drug and vaccine design is crucial to fight malaria. The aim of this project has been to analyse a novel gene and protein in Plasmodium. A short nucleotide fragment was originally identified in Plasmodium chabaudi chabaudi (AS) and the complete sequence subsequently obtained using Vectorette PCR. A singleexon gene was identified and Southern analysis showed the presence of a single copy in the P. chabaudi genome. Analysis of the protein secondary structure revealed a multidomain molecule consisting of an N-terminal secretion signal, two Scavenger Receptor Cysteine-Rich (SRCR) domains, three Limulus factor C, Coch-5b2 and Lgl1 (LCCL) modules and an LH2/PLAT domain. These motifs all have adhesive properties, and the protein was subsequently named Plasmodium SRCR LCCL Adhesive-like Protein (PSLAP). Multiple sequence alignment established that PSLAP is highly conserved within Plasmodium and also identified a paralogue in Toxoplasma gondii, suggesting it may play a specific and vital role in apicomplexan biology. Results from indirect immunofluoresence assays showed a punctate expression pattern contained within the parasite, indicating that the protein is distributed in vesicles. Northern analysis and immunofluorescence co-localisation studies showed transcription and expression in blood-stage gametocytes, demonstrating that PSLAP is a sexual stage protein.

description: Production of the doubly strange $Ξ$ baryon in heavy-ion collisions at \textrm{SIS} energies is studied in a relativistic transport model that includes perturbatively the strangeness-exchange reactions $\bar{K}Λ\to πΞ$ and $\bar{K}Σ\to πΞ$. Taking the cross sections for these reactions from the predictions of a hadronic model, we find that the $Ξ$ yield is about $10^{-4}$ in central collisions of $% ^{58}$Ni + $^{58}$Ni at $E/A=1.93$ \textrm{GeV}. The $Ξ$ yield is further found to be more sensitive to the magnitude of the cross sections for strangeness-exchange reactions than to the medium effects due to modified kaon properties. We have also made predictions for $Ξ$ production in Au+Au collisions at energies from 1 to 2 GeV/nucleon.

The aim of the study was to assess the determinants of maize production changes in Ukraine in the context of internal and global conditions. The work presents changes in production, consumption and prices in Ukraine against their counterparts in the world. In light of the research, it has been shown that there is an increase of integration of the Ukrainian maize market with global markets. This phenomenon was supported by the increase in demand for maize on global markets caused by the development of biofuel production and the relatively low costs of cereal production in Ukraine. / Synopsis.

Environmental heterogeneity in models predicting criminal recidivism: Isolating the contribution of individual-level characteristics

Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: In this dissertation, the links between characteristics of an offender, characteristics of the environment the offender is released to and the likelihood of criminal recidivism are analyzed in detail. The county is used to proxy the environment of release, and differences among the 40 counties included are measured in terms of the social, economic and judicial conditions present therein. To mitigate some of the problems associated with small and ill-conditioned samples, the Generalized Maximum Entropy method is used to assess these links. Additionally, the GME framework easily extends to allow for group-wise heteroskedastic error to account for unbalanced county-level samples. Information parsing is performed to assess the relative importance of knowledge about the 'individual' and the 'environment' in reducing uncertainty about the risk of recidivism. The analysis suggests that in addition to an individual's youthfulness and criminal history, the social, economic and judicial climates in the environment of release do influence the likelihood of recidivism. However, these influences are often indirect and are only seen when a comprehensive analysis of sub-groups is conducted.

Testing lumpability and conditional independence in Markovian models
Creators: name: Baran, Robert Henry
Publisher: name: American University
Year: 2023

description: A common practice in time series analysis is to lump the observations into a smaller set of categories and then fit a stationary Markov model to the lumped sequence. This paper examines conditions under which lumping preserves regular (first order) Markov chains and enhances their detectability by standard methods. Chi-squared tests are developed to decide whether these conditions are satisfied by any specific lumpability hypothesis concerning a time series. These tests are used to screen out ineffective lumping schemes when there is reason to believe the data realize a regular chain or when the sequence is too short to estimate a higher order model. Screening lumpability hypotheses adds credibility to higher order models in the sense that they reflect properties of the raw data as opposed to being artifacts of lumping.

description: The article discusses the methodical problems of operationalization of the agriculture sustainable development with the use of the eco-efficiency concept and the DEA method. On the basis of the literature review, dilemmas faced by the researcher adopting this research perspective have been identified. Although the application of these methods allows to reduce the problems related to the selection of weights and reference points, as well as various units in which the inputs and effects of agricultural activity are expressed, at the same time it requires the assumption that: 1) the research will not take into account a random factor; 2) the analysed group of entities is homogenous; 3) exists interchangeability of capital and environmental inputs; 4) exist institutional limitations of over-exploitation of environmental resources. / Synopsis. W artykule poruszony zostaje problem metodycznych uwarunkowań operacjonalizacji paradygmatu zrównoważonego rozwoju rolnictwa z wykorzystaniem koncepcji ekoefektywności i metody obwiedni danych, DEA. Na podstawie przeglądu literatury zidentyfikowano dylematy przed jakimi staje badacz przyjmujący te perspektywę badawczą. Choć zastosowanie omawianych metod pozwala na ograniczenie problemów związanych z doborem wag i punktu odniesienia, a także różnych jednostek, w których wyrażone są nakłady i efekty działalności rolniczej, wymaga jednocześnie, przyjęcia założenia o nieuwzględnianiu w badaniach czynnika losowego i homogeniczności badanej grupy podmiotów, a także o wymienności nakładów kapitałowych i środowiskowych oraz istnieniu instytucjonalnych ograniczeń nadmiernej eksploatacji zasobów ekologicznych.

description: Resistive plate chambers (RPC) lined with $^{10}B_{4}$C neutron converters is a promising cost effective technology for position-sensitive thermal neutron detection capable to outperform $^{3}$He-based detectors in terms of spatial resolution and timing. However, as for the other types of gaseous detectors with a single layer of $^{10}B_{4}$C at normal beam incidence, the detection efficiency to thermal neutrons of a single-gap $^{10}B$-RPC is only about 6%. Aiming to overcome this limitation, we introduce a multi-layer $^{10}B$-RPCs detector with a stack of ten double-gap hybrid RPCs. A description of the detector design and the results of its characterization performed at the TREFF neutron beamline at the FRM II neutron facility are presented. The results demonstrate that the detection efficiency exceeds 60% for neutrons with a wavelength of 4.7 Å and the spatial resolution (FWHM) is about 0.25 mm and 0.35 mm in the X and Y direction, respectively.

description: This dissertation examines the past forty years of thinking about development and the environment in the planning of large dams in Southeast Asia. It does so through an historical, in-depth analysis of dam plans and related environmental and social studies along the lower Mekong River basin. The dissertation studies whether there has been a paradigmatic shift of thinking over time and, if so, what factors would best account for such a change. The dam plans of the lower Mekong River basin are examined during three eras of development between 1951 and 1995. These plans are examined in the context of four major paradigms of development and the environment: frontier economics, environmental protection, resource management, and political ecology. Original planning documents of the Mekong River Committee form the basis for much of this dissertation's examination. Interviews with former and present Mekong River Committee officials and other individuals closely associated with dam plans provided further data. Additional research involved using published material and articles from the international press and independent research organizations. The author found that there was a shift regarding development and the environment from a frontier economics paradigm to an environmental protection paradigm in the context of the lower Mekong River basin. The paradigm shift was not as significant as might be expected however, and occurred near the end of the development eras under study in the lower Mekong River basin. The author further found there was discrepancy between the paradigm that project documents claimed was being followed and the paradigm actually represented in the documents. The author discovered that the shift in thinking that did occur was largely a result of two factors: new decision-makers, with fresh ideas and new modes of thinking, who drew up project documents; and new actors, notably regional and international NGOs, which put pressure on international financial institutions to shift the development and environment paradigm of the Mekong River Committee.

description: The properties of the reduced density matrix describing an interval of N sites in an infinite chain of free electrons are investigated. A commuting operator is found for arbitrary filling and also for open chains. For a half filled periodic chain it is used to determine the eigenfunctions for the dominant eigenvalues analytically in the continuum limit. Relations to the critical six-vertex model are discussed.

description: We propose a new method for investigating atmospheric inhomogeneities in exoplanets through transmission spectroscopy. Our approach links chromatic variations in conventional transit model parameters (central transit time, total and full durations, and transit depth) to atmospheric asymmetries. By separately analyzing atmospheric asymmetries during ingress and egress, we can derive clear connections between these variations and the underlying asymmetries of the planetary limbs. Additionally, this approach enables us to investigate differences between the limbs slightly offset from the terminator on the dayside and the nightside. We applied this method to JWST's NIRSpec/G395H observations of the hot Saturn exoplanet WASP-39 b. Our analysis suggests a higher abundance of CO2 on the evening limb compared to the morning limb and indicates a greater probability of SO2 on the limb slightly offset from the terminator on the dayside relative to the nightside. These findings highlight the potential of our method to enhance the understanding of photochemical processes in exoplanetary atmospheres.

description: The CAP, despite strong criticisms from various expert cycles, enabled and still allows the development of European agriculture and rural areas. The current discussion about the CAP’s new architecture after 2020 stimulates a review of different positions and formulation of new views. For years, one of the key postulates has been better CAP targeting and a higher value for money. The objective of this publication is to present key developments that took place during this debate in the view of global political, economic, environmental and technological conditions. The authors formulated the following hypothesis: the coming CAP reform will bring about a fundamental change of the policy implementation model but the new CAP will not contribute to a stronger and measurable result-based orientation. The political consensus of supporting small farms will be continued at the expense of limiting support to the large farm operators. The main method used is online research, review of literature, and various analysis and documents. / Synopsis. WPR UE, pomimo stałej, często ostrej, krytyki różnych środowisk, umożliwiała i nadal wspiera rozwój europejskiego rolnictwa i obszarów wiejskich. Aktualnie trwająca dyskusja nad jej kształtem po 2020 roku skłania do dokonania przeglądu stanowisk i wyrażenia własnych poglądów. W trwającej dyskusji od lat podnoszony jest pogląd o konieczności lepszego ukierunkowania WPR na skonkretyzowane cele dla uzyskania wyższej efektywności funduszy publicznych. Głównym celem opracowania jest dokonanie przeglądu ważniejszych wydarzeń, jakie miały miejsce w trakcie zainicjowanej w 2016 r. przez Komisję Europejską debaty, w tym sfinalizowanych konsultacji społecznych, na tle globalnych uwarunkowań politycznych, ekonomicznych, środowiskowych i technologicznych. Autorzy formułują hipotezę w następującym brzmieniu: Najbliższa reforma WPR choć przyniesie fundamentalne zmiany modelu wdrażania WPR, to jednak nie zapewni to jej znacznie silniejszego niż obecnie ukierunkowania na osiąganie zdefiniowanych i mierzalnych celów. Polityczny konsensus dotyczący wzmocnienia wsparcia na rzecz drobnych gospodarstw rolnych będzie kontynuowany kosztem ograniczenia wsparcia dla dużych operatorów. Oznacza to, że legitymizacja realizowanej polityki opierać się będzie głównie na społecznych i środowiskowych jej aspektach. Główną metodą badawczą jest przegląd i analiza obszernej literatury przedmiotu oraz dokumentów, analiz i ekspertyz.

Quiver Matrix Mechanics for IIB String Theory (I): Wrapping Membranes and Emergent Dimension

description: In this paper we present a discrete, non-perturbative formulation for type IIB string theory. Being a supersymmetric quiver matrix mechanics model in the framework of M(atrix) theory, it is a generalization of our previous proposal of compactification via orbifolding for deconstructed IIA strings. In the continuum limit, our matrix mechanics becomes a $(2+1)$-dimensional Yang-Mills theory with 16 supercharges. At the discrete level, we are able to construct explicitly the solitonic states that correspond to membranes wrapping on the compactified torus in target space. These states have a manifestly $SL(2,\integer)$-invariant spectrum with correct membrane tension, and give rise to an emergent flat dimension when the compactified torus shrinks to vanishing size.

description: We investigate light transport in novel three-dimensional scattering systems generated according to subrandom sequences and demonstrate subdiffusive behavior typical of wave transport in disordered systems at the critical point for metal-insulator-transitions but in a wider range of parameters. Specifically, we solve the electromagnetic multiple scattering problem using the Green's matrix spectral theory for aperiodic systems based on Halton, Sobol, and stochastic Latin-Hypercube sequences. By studying the Thouless number and the level spacing statistics of the electromagnetic resonances at different scattering density we demonstrate that light transport in deterministic Halton and Sobol structures exhibit multifractal behavior characterized by inverse power law scaling of level spacing statistics across a wide range of densities of dipolar scatterers. On the other hand, this scenario is absent in the stochastic Latin-Hypercube array, whose behavior resembles instead standard diffusion in uniform random media. Our findings establish a connection between subdiffusion and subrandom aperiodic order and provide a novel strategy to design three-dimensional structures with multifractal properties over a broad spectral range.
