description: Short baseline neutrino experiments, like LSND and MiniBooNE experiments, pointed towards the existence of eV mass scale sterile neutrinos. To reconcile sterile neutrinos with cosmology self interaction between sterile neutrinos has been studied. We analysed Planck cosmic microwave background (CMB) data with self-interacting sterile neutrino (SI$ν$) and study their impact on inflation models. The fit to the CMB data in SI$ν$ model is as good as the fit to $Λ$CDM model. We find that the spectral index ($n_s$) values shift to $0.9361\pm 0.0055$ in SI$ν$ model. This has significant impact on the validity of different inflation models. For example the Starobinsky and quartic hilltop model, which were allowed within $Λ$CDM cosmology, are ruled out. On the other hand some models like natural and Coleman-Weinberg inflation are now favoured. Therefore, the existence of self interacting sterile neutrinos with eV order of mass will play an important role in the selection of correct inflation model.

description: Formulation of fertilization plan is important task in agricultural production, but frequently performed by advisors without necessary information about individual plots and fertilisation practices applied by individual farmers. With increasing concerns for environment and sustainable production it is therefore important that fertilization planning is done by farmers. High fertilizers' prices also urge to their rational application, achievable only on the basis of plans for several years. In the article an electronic tool for fertilization plan formulation is presented. It is developed as a multi-criteria decision making model based on mathematical programming techniques. Hypothetical case illustrates its application as well as strengths and weaknesses of methodology applied.

description: The quantum transport properties of the ultrathin silver nanowires are investigated. For a perfect crystalline nanowire with four atoms per unit cell, three conduction channels are found, corresponding to three $s$ bands crossing the Fermi level. One conductance channel is disrupted by a single-atom defect, either adding or removing one atom. Quantum interference effect leads to oscillation of conductance versus the inter-defect distance. In the presence of multiple-atom defect, one conduction channel remains robust at Fermi level regardless the details of defect configuration. The histogram of conductance calculated for a finite nanowire (seven atoms per cross section) with a large number of random defect configurations agrees well with recent experiment.

description: Gravitational wave observations offer unique opportunities to probe gravity in the strong and dynamical regime, which was difficult to access previously. We here review two theory-agnostic ways to carry out tests of general relativity with gravitational waves, namely (i) parameterized waveform tests and (ii) consistency tests between the inspiral and merger-ringdown portions. For each method, we explain the formalism, followed by results from existing events, and finally we discuss future prospects with upgraded detectors, including the possibility of using multi-band gravitational-wave observations with ground-based and space-borne interferometers. We show that such future observations have the potential to improve upon current bounds on theories beyond general relativity by many orders of magnitude. We conclude by listing several open questions that remain to be addressed.

Life Course Effects of Polyvictimization: Associations with Depression and Crime
Creators: name: Carbonaro, Richard
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Exposure to multiple forms of victimization has been shown to have increasingly negative outcomes, but their unique trajectory-setting effects have been largely unexplored. Using a life course approach, this paper examines the trajectory-setting effects of childhood polyvictimization into early adulthood. I use a nationwide sample including 3,652 respondents after cleaning and preparation. Seemingly unrelated regressions were used to predict depression and criminal behavior in childhood and adulthood. Results suggest childhood polyvictimization sets children on a negative trajectory which grows increasingly worse through the life course. Researchers and interventions should take these trajectory-setting effects into account when attempting to aid polyvictims.

title: The significance of the life and writings of ʿAbdullāh al-Hararī (d. 1429/2008): A response to Wahhābī influence in the Levant
Creators: name: Mohammad, Bakir Mohammad Saleh
Publisher: name: University of Glasgow
Year: 2021

description: With the rise of modern-day Islamic reformers, ʿAbdullāh b. Muḥammad al-Hararī (d. 1429/2008) stands out from his contemporaries. This study does not merely shed light on al-Hararī’s life and works. Rather, it is also concerned with the impact he had on the study of Islam in the 21st century. By analysing the majority of al-Hararī’s works, a unique insight into his emphasis on ʿaqīda (Islamic creed) and the impact he had on anti-Wahhābī discourse can be deduced. As the title indicates, al-Hararī’s daʿwa (lit. call) grew to become one of the most influential and controversial daʿwas in Lebanon, and consequently the Islamic World. This research is primarily triggered by the scarcity of adequate studies in Western Academia on al-Hararī’s life, coupled with the rise of anti-Hararī rhetoric in the Arab World. While it would be worthwhile to examine the practical methodologies through which al-Hararī’s ideology spread – via the Association of Islamic Charitable Projects and its worldwide branches – this thesis is chiefly concerned with the discourse surrounding the ideology adopted and promoted by al-Hararī, including his views on anthropomorphism, taʾwīl, tabarruk amongst other concepts. As a reformer, he sought to unify Muslims by stressing the importance of ʿaqīda, as well as devoting much of his life to warning against what he calls “al-Firaq al-Thalāth”, or the Three Sects, namely: Wahhābīs, Ikhwānīs and Taḥrīrīs. Even after his death, his impact is becoming increasingly noticeable.
Second-Order Bulk-Boundary Correspondence in Rotationally Symmetric Topological Superconductors from Stacked Dirac Hamiltonians

description: Two-dimensional second-order topological superconductors host zero-dimensional Majorana bound states at their boundaries. In this work, focusing on rotation-invariant crystalline topological superconductors, we establish a bulk-boundary correspondence linking the presence of such Majorana bound states to bulk topological invariants introduced by Benalcazar et al. We thus establish when a topological crystalline superconductor protected by rotational symmetry displays second-order topological superconductivity. Our approach is based on stacked Dirac Hamiltonians, using which we relate transitions between topological phases to the transformation properties between adjacent gapped boundaries. We find that in addition to the bulk rotational invariants, the presence of Majorana boundary bound states in a given geometry depends on the interplay between weak topological invariants and the location of the rotation center relative to the lattice. We provide numerical examples for our predictions and discuss possible extensions of our approach.

description: We recalculated pion virtual Compton scattering in perturbative QCD in this paper. Our calculation avoids some deficiencies in existing literatures, and treats real Compton scattering as a limit case in which the mass of the virtual photon equals to zero. Expressions of the hard scattering amplitudes from 10 independent diagrams are given explicitly in the text. By comparing the effects of different distribution amplitudes on physical observables, we studied the self-consistence of pQCD calculation of this problem.

Publisher: name: University of Massachusetts Amherst
Year: 2018

description: This thesis is the written portion of my experience as a director, staging an adaptation of the traditional Iranian theater form, Ta’zieh, for my thesis project. I start with a brief description of our adapted performance, followed by the inspirations that led to the creation of the piece. I then trace the evolution of the idea from the initial stage to the final performance. I describe the adaptation process in three sections, the story, form, and practice. In each section, in a comparative manner, I write about the ways in which Ta’zieh is traditionally done and elaborate on our decisions while adapting it for a new audience. I explain the challenges of adapting and directing the play outside of its original context and discuss how I worked on making this performance an intercultural experience. I conclude to write how I think these artistic cultural exchanges can connect us between countries and cultures, shed a light on our shared struggles and hopes, and lead us to connect on deeper levels of understanding.

description: No início dos anos 1960, uma jovem escritora despontou no cenário literário do país com uma obra autobiográfica que prometia aos leitores uma revelação de segredos e intrigas políticas envolvendo o ex-presidente Jânio Quadros. Com o sucesso comercial da primeira publicação, adotou uma fórmula que consagrou e prosseguiu escrevendo novas histórias registradas na "verdade nua e crua". Entre autobiografias e romances publicados quarenta e oito livros em três décadas, explorando temas relacionados com a realidade social, política e econômica do país. Por explorar temas espaciais para a época, foi a primeira autora censurada pelo regime civil-militar de 1964 e a terceira com mais livros apreendidos. Mesmo relegado pela crítica literária e acusada de esquerda, comunista e pornográfica pelos censores e segmentos mais conservadores; sua literatura tornou-se sucesso de venda entre as classes populares, que consumiu esse produto cultural através de compra pelo reembolso postal. Sempre se apresentou como escritora de “verdade” e rejeitou ou gravou a escritura de ficção acabou sendo rotulada por “escritora maldita”. Este artigo discute alguns dos rótulos que marcam essa produção literária e a relação entre realidade, “verdade” e ficção a partir do ponto de vista da escritora.

An assessment of the UK model of cooperation with the EU in the area of restrictive measures: broad convergence. - VI. Concluding remarks.
description: This Insight examines how the UK has shaped its sanctions policy from the start of the transition period until the first three months following the UK's withdrawal from the EU. The objective of the Insight is to assess whether the UK has aligned with the EU restrictive measures based on art. 215 TFEU or has made political choices that significantly depart from those of the EU in the adoption of sanctions regimes. The following trends may be high-lighted. On the one hand, the UK has shaped its sanctions policy independently of the EU. In particular, the UK enacted a global human rights sanctions regime that presents differences from that of the EU and has on several occasions been applied independently of the EU in the practice. On the other hand, the UK has incorporated most of the EU sanctions acquis and has also aligned with the restrictive measures adopted by the EU in specific cases. Despite the presence of differences in the sanctions regimes of the EU and the UK, at the moment the policy choices of the two subjects of international law are similar. However, in the future, the divergence between the sanctions regimes applicable in the EU and UK legal orders may grow, for instance with respect to the designations of the addressees of restrictive measures.

description: We outline in detail the properties of generalized parton distributions (GPDs), which contain new information on the structure of the nucleon and which enter the description of hard exclusive reactions. We highlight the physics content of the GPDs and discuss the quark GPDs in the large $N_c$ limit and within the context of the chiral quark-soliton model. Guided by this physics, we then present a general parametrization for these GPDs. Subsequently we discuss how these GPDs enter in a wide variety of hard electroproduction processes and how they can be accessed from them. We consider in detail deeply virtual Compton scattering and the hard electroproduction of mesons. We identify a list of key observables which are sensitive to the various nucleon structure aspects contained in the GPDs and which can be addressed by present and future experiments.

A new instrument to measure the global EoR signal (Internal Engineering Memo)
Creators: name: Razavi-Ghods, Nima
Publisher: name: Zenodo
Year: 2018
Subjects: Radio Cosmology

description: This engineering note evaluates a different approach for measuring the global EoR signal following in the
 footsteps of EDGES, LEDA, and other such instruments. The key principle of this approach relies on a) the
 scalability of the antenna system, namely the antenna itself, the feed ports as well as the ground plane b) an
 exceptionally good match between the antenna and receiver system to reduce systematic uncertainty and c) an
 updated approach for measuring the antenna and receiver calibration parameters in the field without relying at
 all on any laboratory characterization. The advantage of this approach is to have a very well matched system
 comprised of several scaled antennas working over a wide bandwidth such as 3:1 or 4:1 and providing extra degrees
 of freedom to remove antenna beam chromatic effects which are otherwise diffcult to calibrate out.
Revisiting the duality of computation: an algebraic analysis of classical realizability models
Creators: name: Miquey, Étienne
Publisher: name: arXiv
Year: 2019
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: In an impressive series of papers, Krivine showed at the edge of the last decade how classical realizability provides a surprising technique to build models for classical theories. In particular, he proved that classical realizability subsumes Cohen's forcing, and even more, gives rise to unexpected models of set theories. Pursuing the algebraic analysis of these models that was first undertaken by Streicher, Miquel recently proposed to lay the algebraic foundation of classical realizability and forcing within new structures which he called implicative algebras. These structures are a generalization of Boolean algebras based on an internal law representing the implication. Notably, implicative algebras allow for the adequate interpretation of both programs (i.e. proofs) and their types (i.e. formulas) in the same structure. The very definition of implicative algebras takes position on a presentation of logic through universal quantification and the implication and, computationally, relies on the call-by-name $λ$-calculus. In this paper, we investigate the relevance of this choice, by introducing two similar structures. On the one hand, we define disjunctive algebras, which rely on internal laws for the negation and the disjunction and which we show to be particular cases of implicative algebras. On the other hand, we introduce conjunctive algebras, which rather put the focus on conjunctions and on the call-by-value evaluation strategy. We finally show how disjunctive and conjunctive algebras algebraically reflect the well-known duality of computation between call-by-name and call-by-value.

description: In this work, we study the Wigner phase-space representation of qubit states encoded in continuous variables (CV) by using the Gottesman-Kitaev-Preskill (GKP) mapping. We explore a possible connection between resources for universal quantum computation in discrete-variable (DV) systems, i.e. non-stabilizer states, and negativity of the Wigner function in CV architectures, which is a necessary requirement for quantum advantage. In particular, we show that the lowest Wigner logarithmic negativity of qubit states encoded in CV with the GKP mapping corresponds to encoded stabilizer states, while the maximum negativity is associated with the most non-stabilizer states, H-type and T-type quantum states.

description: We calculate the asymmetries for the processes $\vecγ+\vec p\to Λ_c^+ (Σ_c^+)+\bar{D^0}$ and $\vecγ+\vec p\to Λ_c^+ (Σ_c^+)+\bar{D^*}$, induced by circularly polarized photons on a polarized proton target in the framework of an effective Lagrangian model. We found large and positive values for the asymmetry induced by the $z-$component of the proton polarization, in a wide energy region, from threshold up to $E_γ=70$ GeV. In the case of pseudoscalar meson photoproduction, the predictions are qualitatively model-independent. For $D^*$-photoproduction, there is a strong dependence of the asymmetries on $NΛ_c D(D^*)$-coupling constants.

description: High-quality epitaxial ferrites, such as low-damping MgAl-ferrite (MAFO), are promising nanoscale building blocks for all-oxide heterostructures driven by pure spin current. However, the impact of oxide interfaces on spin dynamics in such heterostructures remains an open question. Here, we investigate the spin dynamics and chemical and magnetic depth profiles of 15-nm-thick MAFO coherently interfaced with an isostructural $\approx$1-8-nm-thick overlayer of paramagnetic CoCr$_2$O$_4$ (CCO) as an all-oxide model system. Compared to MAFO without an overlayer, effective Gilbert damping in MAFO/CCO is enhanced by a factor of $>$3, irrespective of the CCO overlayer thickness. We attribute this damping enhancement to spin scattering at the $\sim$1-nm-thick chemically disordered layer at the MAFO/CCO interface, rather than spin pumping or proximity-induced magnetism. Our results indicate that damping in ferrite-based heterostructures is strongly influenced by interfacial chemical disorder, even if the thickness of the disordered layer is a small fraction of the ferrite thickness.

description: The synthesis and structure of [Cu(2-Br-4-HOpy)2(2-Br-4-pyone)2](ClO4)2 • 2(2-Br-4-HOpy) • 2(2-Br-4-pyone) is reported [2-Br-4-HOpy = 2-bromo-4-hydroxypyridine; 2-Br-4-pyone = 2-bromo-(1H)4-pyridone]. The compound forms as a co-crystal in the triclinic P-1 space group with four-coordinate Cu(II) ions and perchlorate geganions interacting with both the hydroxypyridine and pyridone forms of the organic molecule through hydrogen and halogen bonding. The coordination complex exhibits the unusual coordination motif of having both the hydroxypyridine and pyridone tautomers of the ligand coordinated to the same metal ion. The isolation of the Cu complex by the organic groups suggests an absence of magnetic exchange within the sample which is confirmed by variable temperature magnetization measurements and EPR data.

Scutum with very indistinct pattern: posterolateral areas (lateral of dorsocentral lines and posterior to presutural intra-alar bristle) with slightly bluish reflections. Scutellum hardly velvety. Mid tibia with two short posteroapical bristles of subequal length.
Male unknown.
Female terminalia (Figs. 287–289): Sternite 7 with large, bare (devoid of bristles and microtrichia), shining black posteromedial projection (sternite otherwise with the usual grey pruinosity). Fused tergite 10 + cerci completely rounded posterolaterally.
 Type material. Holotype ♀ and 7 ♀♀ paratypes (DEBU): GUATEMALA, Dpto. Baja Verapaz, 4.8 km E Purulhá, 1,680 m, 29.vi–3.vii.1993, exterior FIT, Ashe & Brooks. Other paratypes: GUATEMALA. Dpto. Baja Verapaz: 1 ♀, 7.4 km S Purulhá, 1,650 m, 2.vii.1993, FIT, Ashe & Brooks (DEBU). Dpto. Zacapa: 5 mi N San Lorenzo, 1 ♀, 4–18.vii.1986, 1 ♀, 7–10.vii.1986, FIT, J.M. Campbell (DEBU). MEXICO. Chiapas: 2 ♀♀, Lagos de Montebello, Lago Pojoj, 1,500 m, 2–12.vi.1990, FIT, B. Gill (DEBU). Note: We decided to name this species even though the male is still unknown. The female has highly distinctive terminalia and is the only representative of this small species group in Mexico and Guatemala. When the male is discovered it will be readily associated with this species.
 Etymology. The species name refers to the shining posterior half of female sternite 7 which is diagnostic for this species (Lat. nitens: shining, glittering).
 Distribution (Map 11). Only known from southern Mexico (Chiapas) and Guatemala at altitudes between 1,500 and 1,680 m.
 Discussion. The female of L. posteronitens sp.n. is easily recognisable by its large, shining black posteromedial projection of sternite 7. Otherwise it is very similar to L. tapanti sp.n. from Costa Rica and Panama.

description: The evolution of digital payments has significantly impacted consumer behavior and business operations. This study aimed to explore the role of fintech innovations, such as mobile wallets and contactless payments, in shaping consumer habits. Using a mixed-methods approach, the research analyzed data from 500 consumers and 50 businesses, showing that mobile payment transactions rose by 47% from $4.7 trillion in 2021 to $6.9 trillion in 2023. Results indicated that 73% of consumers are more likely to make impulse purchases with digital payments, though 68% still cite security as their top concern. The study concludes that while digital payments offer convenience and drive sales, enhancing security remains crucial for widespread adoption.
The Effects of Reward and Risk Level Associated with Speeded Actions: Evidence from Behavior and Electroencephalography

description: Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) and the probability that a Go signal would follow (Go-probability) were presented prior to a Go/NoGo signal (Trial Information Period). The behavioral results (from both Chapters 2 and 3) showed that larger amount of rewards can motivate people to respond faster, and this effect was modulated by the assessed risk, suggesting that decisions for actions are based on a systematic trade-off between rewards and risks. The EEG data showed that motor beta oscillations from the two studied brain regions reflected different levels of motivation towards a motor response across different reward and risk levels. Specifically, the lower beta power associated with higher reward and lower risk level. Collectively, the results provide a mechanistic understanding of how motivational cues are translated into action outcomes via modulating patterns of brain oscillations.
The Problems in Rural English Teaching and the Optimization Path: A Study Based on the Chinese General Social Survey Data

description: The new curriculum, new ideas and new requirements concerning English teaching have made the rural English teaching face unprecedented challenges. There are many problems contributing to the poor effect of rural English teaching, such as outdated teaching equipment, unreasonable curriculum design, insufficient teaching staff, asymmetrical teaching content, family education and students' personal problems. Based on the Chinese General Social Survey data, it is found that in terms of English reading, English speaking or English writing, the current English level of China's rural residents is lagging behind. From the average, the reading level of rural residents is better than the speaking and writing level, but the paired T-test results show that there are no significant differences between them, suggesting that under the current system of rural English teaching, the English level of rural residents is constrained to a low level. To improve the rural English teaching in the future, it is necessary to pay close attention to the following aspects: stabilizing the investment in rural education; optimizing the English teaching content; converting the philosophy of education; increasing teacher training; establishing the new linkage system.
Evaluating the Toxicity and Formation of Halobenzoquinones in Point-of-Use Chlorinated Drinking Water
Creators: name: Hung, Stephanie

Year: 2018

description: Chlorine has effectively reduced the prevalence of waterborne diseases, however there are secondary consequences to this public health advancement. Disinfection byproducts (DBPs) are chemicals formed when chlorine reacts with natural organic matter (NOM) in water. A new class of DBPs, halobenzoquinones (HBQs), has recently been identified and data suggests it could be potentially carcinogenic and up to 1000 times more toxic than some regulated DBPs. So far, in vitro studies have assessed HBQ toxicity without taking into account its transformation in cell media into potentially less toxic compounds. This study evaluated the toxic effects of one HBQ, 2,6-DCBQ, and its transformed derivatives on colon epithelial and liver hepatoma cell lines by measuring intracellular reactive oxygen species production and cell viability post-DCBQ exposure. In addition, to better quantify the trade-off between exposure to waterborne pathogens and 2,6-DCBQ, the inactivation of a virus indicator (MS2), and formation of DCBQ were determined in chlorinated surface waters. Dose-dependent toxic effects were observed in both cell lines and transformed DCBQs were observed to be less toxic than their parent compound. MS2 inactivation occurred immediately post-chlorination, but DCBQ was detected simultaneously. Such findings indicate that this compound is toxic to human cells, including colon epithelial cells, which may be pertinent due to the possible association between chlorinated waters and colon cancer. Findings also suggest this DBP may be relevant in developing countries because HBQs may form in point-of-use chlorinated drinking waters. Furthermore, observed reduction in toxicity of media-transformed DCBQs calls current literature on HBQ toxicity into question.

description: The phase diagram of the organic superconductor $κ$-(BEDT-TTF)$_2$Cu[N(CN)$_2$Cl has been investigated by ultrasonic velocity measurements under helium gas pressure. Different phase transitions were identified trough several elastic anomalies characterized from isobaric and isothermal sweeps. Our data reveal two crossover lines that end on the critical point terminating the first-order Mott transition line. When the critical point is approached along these lines, we observe a dramatic softening of the velocity which is consistent with a diverging compressibility of the electronic degrees of freedom.

description: Lately, generative adversarial networks (GANs) have been successfully applied to zero-shot learning (ZSL) and achieved state-of-the-art performance. By synthesizing virtual unseen visual features, GAN-based methods convert the challenging ZSL task into a supervised learning problem. However, GAN-based ZSL methods have to train the generator on the seen categories and further apply it to unseen instances. An inevitable issue of such a paradigm is that the synthesized unseen features are prone to seen references and incapable to reflect the novelty and diversity of real unseen instances. In a nutshell, the synthesized features are confusing. One cannot tell unseen categories from seen ones using the synthesized features. As a result, the synthesized features are too subtle to be classified in generalized zero-shot learning (GZSL) which involves both seen and unseen categories at the test stage. In this paper, we first introduce the feature confusion issue. Then, we propose a new feature generating network, named alleviating feature confusion GAN (AFC-GAN), to challenge the issue. Specifically, we present a boundary loss which maximizes the decision boundary of seen categories and unseen ones. Furthermore, a novel metric named feature confusion score (FCS) is proposed to quantify the feature confusion. Extensive experiments on five widely used datasets verify that our method is able to outperform previous state-of-the-arts under both ZSL and GZSL protocols.

description: Der Artikel analysiert die Bewertungskriterien für den Abituraufsatz im Fach Deutsche Sprache und Literatur in der DDR sowie deren Entwicklung von den 1950er Jahren bis 1989 und gibt einen Einblick in deren Diskussion. Dazu werden Schwerpunkte der Debatten sowohl auf bildungspolitischer und -administrativer Ebene als auch auf der Ebene der schulischen Praxis herausgearbeitet. Anhand der ausgewerteten Dokumente kann gezeigt werden, wie sich die Bewertungsrichtlinien im Zusammenspiel der Akteure auf unterschiedlichen Ebenen des Bildungssystems weiterentwickelt haben. Zum anderen spiegeln die Diskussionen, dass trotz aller Versuche zur Durchsetzung einheitlicher, objektiver Standards subjektive Bewertungsspielräume fortbestanden und Lehrkräfte einen ständigen Balanceakt zwischen Objektivierung und pädagogischem Ermessen zu leisten hatten.
