description: The resonator-induced phase (RIP) gate is a multi-qubit entangling gate that allows a high degree of flexibility in qubit frequencies, making it attractive for quantum operations in large-scale architectures. We experimentally realize the RIP gate with four superconducting qubits in a three-dimensional (3D) circuit-quantum electrodynamics architecture, demonstrating high-fidelity controlled-Z (CZ) gates between all possible pairs of qubits from two different 4-qubit devices in pair subspaces. These qubits are arranged within a wide range of frequency detunings, up to as large as 1.8 GHz. We further show a dynamical multi-qubit refocusing scheme in order to isolate out 2-qubit interactions, and combine them to generate a four-qubit Greenberger-Horne-Zeilinger state.

description: El movimiento de la escuela inclusiva, de origen anglosajón, se extiende en España ante los planteamientos que la educación especial y la atención a la diversidad confieren al alumnado  con necesidades educativas especiales (n.e.e. de aquí en adelante). En esta línea, nos aproximamos al concepto y al pensamiento de la inclusión para pasar, en un segundo momento, a plantearnos cuáles son las posibilidades que las tecnologías de la información y la comunicación ofrecen en el aula inclusiva. En este sentido, las aplicaciones informáticas y los nuevos entornos gráficos permiten al educador generar materiales propios sin necesidad de grandes conocimientos en informática. Finalmente, con la intención de conocer un poco más las particularidades del diseño de medios digitales, trabajamos el concepto de accesibilidad y sobre su base, se exponen algunas pautas a tener en cuenta a la hora de generar software para la enseñanza.

The inclusive school movement, of Anglo-Saxon origin, is spreading in Spain in view of the approaches that special education and attention to diversity give to students with special educational needs (hereinafter referred to as SEN). In this line, we approach the concept and thought of inclusion to go on, in a second moment, to consider the possibilities that information and communication technologies offer in the inclusive classroom. In this sense, computer applications and new graphic environments allow educators to generate their own materials without the need for extensive knowledge of computers. Finally, with the intention of getting to know a little more about the particularities of digital media design, we work on the concept of accessibility and, based on this, we set out some guidelines to take into account when generating software for teaching.

description: We investigated the impact of wildfires on maximum daily 8-hour average ozone concentrations (MDA8 O3) at four sites in Salt Lake City (SLC), Utah for May to September for 2006–2022. Smoke days, which were identified by a combination of overhead satellite smoke detection and surface PM2.5 data and accounted for approximately 9% of the total number of days, exhibited O3 levels 6.8 to 8.9 ppb higher than no-smoke days and were predominantly characterized by high daily maximum temperatures and low relative humidity. A Generalized Additive Model (GAM) was developed to quantify the impact of wildfire contributions to O3. The GAM, which provides smooth functions that make the interpretation of relationships more intuitive, employed 17 predictors and demonstrated reliable performance in various evaluation metrics. The mean of the residuals for all sites was approximately zero for the training and cross-validation data and 5.1 ppb for smoke days. We developed 3 approaches to estimate the contribution of smoke to O3 from the model residuals. These generate a minimum and maximum contribution for each smoke day. The average of the minimum and maximum wildfire contributions to O3 for the SLC sites was 5.1 and 8.5 ppb, respectively. Between 2006–2022, an increasing trend in the wildfire contributions to O3 was observed in SLC. Moreover, trends of the fourth-highest MDA8 O3 before and after removing the wildfire contributions to O3 at the SLC Hawthorne site in 2006–2022 were quite different. Whereas the unadjusted data do not meet the current O3 standard, after removing the contributions from wildfires the SLC region is close to achieving levels that are consistent with meeting the O3 standard. We also found that the wildfire contribution during smoke days was particularly high under conditions of high temperature, high PM2.5 concentration, and low cloud fraction.

description: Temperature is the primary factor affecting the growth and survival of aquatic species. At low temperatures, the metabolic rate decreases significantly. As a result, energy levels and growth rates in fish slow down which reduces the overall aquaculture production. Therefore, a novel thermal model of GiSPVT in terms of design and climatic parameters has been developed. An analytical expression for fishpond temperature and electrical energy has been derived and validated using the special case of the proposed GiSPVT for a particular day. The solar radiation passing through the non-packing area of the semi-transparent PV modules was used to heat the water to maintain the desired temperature. However, for experimental validation, the growth performance of Labeo rohita (26.15 ± 2.4 g) was cultured (90 days) with different conditions: T1bgl, T2agl (inside the greenhouse), T3bgl, T4agl (outside the greenhouse). Specific growth rate (SGR), average weight and weight gain of fishes were significantly higher (p < .05) in the T1bgl group as compared to other groups. Moreover, the SGR was observed 32.6%, 20.2%, and 14.0%, higher in the T4agl as compared to T2agl, T3bgl, and T4agl respectively. Significantly increased growth performance of T1bgl group during winter may be due to the combined effect of geothermal and solar energy integrated systems.

description: This article examines the position of la or Pa rwot, or what I refer to as the royal messen‐ ger, to show the complicated nature of mobility of information and goods in late precolonial and early colonial Acholiland. Using a wide range of sources, such as mission and colonial archives, local histories by both Acholi and missionaries, and the author’s doctoral field research notes, I argue that understanding this office and its holder allow us to comprehend the complex ways through which information and goods moved between subjects and leaders called rwodi (singular: rwot), and from one rwot to another. This article has dual goals: first, to examine the nature of the training of la or Pa rwot, delving into the knowledge and skills of the office holders, and second, to demonstrate the roles of la or Pa rwot in his chiefdom and the transformation of the office, beginning in the 1890s with the British conquest of Acholiland, to 1920. Overall, the article seeks to draw attention to a unique group of men who facilitated the traffic of administrative and diplomatic information and goods in Acholiland and beyond.

description: We construct models of exactly solvable two-particle quantum graphs with certain non-local two-particle interactions, establishing appropriate boundary conditions via suitable self-adjoint realisations of the two-particle Laplacian. Showing compatibility with the Bethe ansatz method, we calculate quantisation conditions in the form of secular equations from which the spectra can be deduced. We compare spectral statistics of some examples to well known results in random matrix theory, analysing the chaotic properties of their classical counterparts.
A Correlational Predictive Study of Core Self-Evaluations, Grit, and Success Expectancy

description: The purpose of this quantitative correlational predictive study is to determine if and to what extent core self-evaluations (CSE), grit, and age, combined and individually predict generalized expectancy for success (GES) in adults ages 18-65 in the United States. The sample size was 115. The theoretical foundation was CSE Theory and the Grit Model. The instruments used for the study were CSE, Grit-S, and GESS-R Scales. The Grit-S and GESS-R had a high level of reliability with Cronbach’s alpha of .72 and .89, respectively. CSE showed a Cronbach’s alpha of .68. Multiple linear regression analysis was performed to measure the predictive relationship between CSE, grit, and age combined and individually, and generalized expectancy for success (GES). The results for CSE, grit, and age combined showed statistically significant results F(3,111) = 27.56, p < .001, CSE showed a direct predictive relationship with GES (ß = .404, t = 4.940, p < .001), and grit showed an inverse predictive relationship with GES (ß = -.360, t = -4.366, p < .001). Age did not show statistically significant results (ß = -.063, t = -.866, p = .388), and the null hypothesis was maintained. The results of this study contribute to the literature on CSE, grit, and generalized expectancy for success. Keywords: core self-evaluations, grit, generalized expectancy for success, non-cognitive factors, success

Nshila
Colonial Zambia
Mobility

description: 'Nshila' (“The Way”), a fortnightly state-sponsored magazine aimed at an African readership in colonial Zambia, participated in the production of a late colonial dis‐ course, which, under the guise of providing affirmation and ‘progressive’ teachings, repackaged long-standing ambitions to control Africans’ spatial mobility and to manage their social and spatial mobility aspirations. While containing some openings through which educated Africans could comment on aspects of a changing reality, 'Nshila' ultimately strove to keep political and mobility ambitions in check, and inculcate in its readers ideals of hard work, personal initiative, and self-help. It thus shared in the late colonial state’s efforts to foster a new form of economic subjectivity among the African population. Crucially, 'Nshila' constructed a narrative of social mobility that identified key channels of African advancement but failed to acknowledge how vastly out of reach these opportunities were for the majority of Africans in Northern Rhodesia. This narrative ambivalently linked social mobility to geographical mobility, certain kinds of which came to stand for achievement and a ‘modern’ lifestyle, while others were deemed disruptive and discouraged. This article combines historical contextuali‐ sation with content and discourse analysis of about eighty magazine issues published between 1958 and 1963.

description: Optical microcavities are a powerful tool to enhance spontaneous emission of individual quantum emitters. However, the broad emission spectra encountered in the solid state at room temperature limit the influence of a cavity, and call for ultra-small mode volume. We demonstrate Purcell-enhanced single photon emission from nitrogen-vacancy (NV) centers in nanodiamonds coupled to a tunable fiber-based microcavity with a mode volume down to $1.0\,λ^{3}$. We record cavity-enhanced fluorescence images and study several single emitters with one cavity. The Purcell effect is evidenced by enhanced fluorescence collection, as well as tunable fluorescence lifetime modification, and we infer an effective Purcell factor of up to 2.0. With numerical simulations, we furthermore show that a novel regime for light confinement can be achieved, where a Fabry-Perot mode is combined with additional mode confinement by the nanocrystal itself. In this regime, effective Purcell factors of up to 11 for NV centers and 63 for silicon vacancy centers are feasible, holding promise for bright single photon sources and efficient spin readout under ambient conditions.

Chinese mobility
Dar es Salaam
Tanzania

migration

description: Chinese migrants in Dar es Salaam, Tanzania, assemble highly variegated forms of transnational mobilities from practices unfolding at various scales—in China, Tanzania, and beyond. This heterogeneity in the constitutive processes and lived experiences of transnational mobilities is obscured when the practitioners of these mobilities are analyzed as, first and foremost, contributors to the aggregate phenomenon of migration flows from one nationally/continentally defined place to another. This is the effect when much of the existing literature on Chinese migrants in Africa analyzes them through a ‘China-Africa’ lens—thereby conjuring a coherent and discrete phenomenon. This framing contributes to a general fixation of research agendas with national-level questions, which in turn tends to flatten highly diverse flows and empirically and analytically segregate them from other, non-Chinese mobilities with which they may share close affinities. This article seeks to push against these effects of methodological nationalism by developing exploratory sketches of the forms of transnational mobilities practiced by three Chinese migrants in Dar es Salaam.

The standard three-term recurrence relation satisfied by the polynomials and different types of asymptotic expansions valid for $n$ large and $α$ small, are used depending on the parameter region. Based on tests of contiguous relations in the parameter $α$ and the degree $n$ satisfied by the polynomials, we claim that a relative accuracy close or better than $10^{-12}$ can be obtained using the module LaguerrePol for computing the functions $L^{(α)}_n(z)$ in the parameter range $z \ge 0$, $-1 < α\le 5$, $n \ge 0$.

Ghana
Ghanaian transnational families

description: Transnational social interactions at the micro-level highlight how migrants and their non-migrant relations sustain various forms of exchanges that crisscross their spatial boundaries. Despite this, 'disembeddedness' and 'fluidity' have been highlighted as distinctive features of mobile subjects, whose local ties become weakened as a result of their mobilities. While connectedness and 'disembeddedness' seem contradictory, they demonstrate multiple dimensions of complex processes of change and continuity that characterise migrants' social experiences. This study uses ‘rootedness’ as a conceptual framework to capture the contradictions. The forms and expression of the concept are highlighted and analysed through interviews of twenty non-migrant parents in Ghana based on their interactions with their migrant offspring abroad from October 2018 to December 2020. The parents’ interviews are complemented by interviews with five of the migrants and other qualitative data-gathering methods that highlight the experi‐ ences of Ghanaian emigrants. Based on its various forms of expression, rootedness emphasises a strong sense of cultural bond to the homeland. The concept also high‐ lights the norm of reciprocity, and the ability of migrants to rupture normative influ‐ ences given the power their migration bestows on them. The analyses bring to the fore that migrants, amidst ruptures and transformations, also remain rooted in their homelands.

description: Photovoltaic (PV) panels play a crucial role in solar systems but are susceptible to efficiency losses caused by rising surface temperatures. This research explores four distinct recycle-type double-pass hybrid PV/T designs, employing steady-state models to cool the PV panels. The first and second designs mount the PV panel on the absorber plate, while the third and fourth designs position it directly over the absorber plate without a glass cover, allowing the sun’s radiation to fall directly on the PV module. The study investigates the significant impacts of varying values of ṁ (0.03–0.15 kg/sec), G (0.3–1.8), D (1.0–6.0), I (300–1000 W/m2), and P (0.4–0.95) on thermal and electrical efficiency, as well as net electrical power generation, taking into account pressure loss during the flow. Through the analytical study, Design-IV demonstrates the highest net electrical power, estimated at 54.82W, which is 6.27% higher than Design-III, achieved at a recycling ratio, mass flow rate, depth ratio, and packing factor of 0.9, 0.15 kg/s, 3, and 0.5, respectively. Additionally, the input parameters are optimized using the Response Surface Methodology (RSM) technique. The analysis of variance (ANOVA) reveals a significant coefficient (R2) value approaching unity, indicating a strong fit of the response model to the analyzed data. By considering both single and multi-objective optimization scenarios, the study identifies optimal parameters for each PV/T design through the interaction of operational parameters. This research contributes to enhancing the efficiency and performance of double-pass recycle-type hybrid PV/T systems, enabling sustainable and effective utilization of solar energy resources.

description: The angular distributions of Drell-Yan charged lepton pairs around the $Z$-boson mass peak probe the underlying QCD dynamics of $Z$-boson production. This paper presents a measurement of the complete set of angular coefficients $A_{0-7}$ describing these distributions in the $Z$-boson Collins-Soper frame. The data analysed correspond to 20.3 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 8$ TeV, collected by the ATLAS detector at the CERN LHC. The measurements are compared to the most precise fixed-order calculations currently available ($\mathcal{O}(α^{2}_{s})$) and with theoretical predictions embedded in Monte Carlo generators. The measurements are precise enough to probe QCD corrections beyond the formal accuracy of these calculations and to provide discrimination between different parton-shower models. A significant deviation from the $\mathcal{O}(α^{2}_{s})$ predictions is observed for $A_{0}-A_{2}$. Evidence is found for non-zero $A_{5,6,7}$, consistent with expectations.

Year: 2023

description: Teachers, who are the most important factor of education, have the great task of inculcating to the learners the knowledge, skill and behavior needed in facing the everchanging society. Thus, the teachers’ task to transmit knowledge requires them to be a highly competent learning facilitators while remaining as a role model soaring with moral integrity. This means that a school must not only have educationally qualified teachers but teachers who are truly dedicated and committed to serve the public specially the learners entrusted to their care. This study is focused to determine teachers’ competency and learners’ performance in English of grade two teachers in Manila particularly in District V. Likewise, the benefits derived from the study hope to provide a springboard to design an intervention scheme towards gearing effort into improving the quality education.

Senegal
buried at "home"
Senegalese in Brazil
Impacts of COVID-19

description: Senegalese abroad invest in solidarity networks that ensure their deceased compatriots are repatriated. Whether through secular or religious initiatives, these efforts reflect a general expectation that one needs to be buried at “home,” “near one’s kin,” and preoccupations with burial following certain rites. In March 2020, however, the Senegalese government halted repatriations of corpses as a COVID-19 prevention measure. The decision sparked huge controversy, leading to the creation of a collective for the repatriation of coronavirus victims, which unsuccessfully sued the government. Based on media analysis and ethnographic fieldwork among Senegalese in Brazil between October 2019 and June 2021, this paper argues that the temporary ban on repatriation of corpses and the stigmatization, at the beginning of the pandemic, of the Senegalese émigrés accused of bringing home “a foreign disease,” lay bare a deeper crisis in the social contract between Senegal and its diasporas. This crisis is epitomized by the gradual loss of prestige of the figure of the émigré and has forced the latter to grapple with the complexity of living where one does not wish to be buried.

Design/methodology/approach – The paper presents an exploratory study using a qualitative approach, including interviews with researchers leading projects and knowledge management experts, besides, as an inquiry and workshop about “The praxis of interdisciplinary research in the context of the EfS Initiative: a first approach” were carried out within the research network. Findings – The results showed that IDR practice has a high impact on researchers' professional paths. The primary motivation among researchers in conducting IDR is the search for solutions to real-world problems that affect social/economic development. Among the identified factors representing a difficulty for practicing IDR inside teams, were: team engagement, research priorities, communication and background–language differences, reconciling different disciplinary norms and practices (background-culture), and identification of partners for collaborations. Practical implications – The paper includes implications for developing a Knowledge Management strategy to increase the efficiency of the collaborative process intrinsic to IDR science team initiatives focused on sustainable development goals. Originality/value – This paper fulfills an identified need to study how IDR teams-science initiative achieves solutions for energy and sustainability matters.

description: The ground axiom is the assertion that the set-theoretic universe is not obtainable by forcing over any inner model. Although this appears at first to be a second-order assertion, it is actually first-order expressible in the language of set theory. This article is the extended abstract for a talk at the 2005 Workshop in Set Theory at the Mathematisches Forschungsinstitut Oberwolfach.

description: The structural complexity of metamaterials is limitless, although in practice, most designs comprise periodic architectures which lead to materials with spatially homogeneous features. More advanced tasks, arising in e.g. soft robotics, prosthetics and wearable tech, involve spatially textured mechanical functionality which require aperiodic architectures. However, a naïve implementation of such structural complexity invariably leads to frustration, which prevents coherent operation and impedes functionality. Here we introduce a combinatorial strategy for the design of aperiodic yet frustration-free mechanical metamaterials, whom we show to exhibit spatially textured functionalities. We implement this strategy using cubic building blocks - voxels - which deform anisotropically, a local stacking rule which allows cooperative shape changes by guaranteeing that deformed building blocks fit as in a 3D jigsaw puzzle, and 3D printing. We show that, first, these aperiodic metamaterials exhibit long-range holographic order, where the 2D pixelated surface texture dictates the 3D interior voxel arrangement. Second, they act as programmable shape shifters, morphing into spatially complex but predictable and designable shapes when uniaxially compressed. Third, their mechanical response to compression by a textured surface reveals their ability to perform sensing and pattern analysis. Combinatorial design thus opens a new avenue towards mechanical metamaterials with unusual order and machine-like functionalities.

description: This study assesses the determinants of urban household poverty in major cities of Ethiopia (in case of Addis Ababa, Dire Dawa, Hawassa, Bahir Dar, Adama and Mekelle). Based on the cost of basic needs approach; in 2004/05, 40.9% households in Addis Ababa, 32.4% households in Dire Dawa, 24.3% households in Adama ,27.5% households in Hawassa, 22.6% households in Bahir Dar, and 28.2% households in Mekelle were below poverty line. During 2010/11 survey Period, these figures were found to be 45.6%, 53%, 33.9%, 36.8%, 30% and 19.3% in case of Addis Ababa, Dire Dawa, Adama, Hawassa, Bahir Dar and Mekelle respectively. The result showed that head count index of poverty increases dramatically except Mekelle. Results based on logistic regression showed; household size was the only significant factor for households being poor in all cities in both survey periods. Educational level of households’ head was also significant on both survey periods in case of Addis Ababa, Hawassa, and Mekelle and it was significant in the first survey period in case of Adama and Bahir Dar. Whereas, educational level of households was not significant contribution on households being poor or not in case of Dire Dawa in both survey periods. Results based on primary data, lack of good governance and rural-urban migration took the lion share on aggravating poverty in these cities.

description: Cosmic dusts are mostly responsible for polarization of the light that we ob- serve from astrophysical objects. They also lead to color-extinction, thermal re- emission and other scattering related phenomena. Dusts are made of small particles which are characterised by their size (radius), composition (matter), and structure (morphology, including porosity). In the present work, we address the question of the role of the dust particle porosity on light polarization and color, using Discrete Dipole Approximation (DDA) light scattering code. To answer this question, we developed an algorithm to generate solid particles of arbitrary values of porosity. In brief, the model considers a given homogeneous structure made of touching dipoles. The dipoles are randomly removed one by one, such that the remaining structure remains connected. We stop the removal process when the desired poros- ity is obtained. Then we study the optical properties of the porous particle. That way, we show how the proper value of the porosity affects the polarization and color of the light scattered by these porous particles. In addition to polarization, porosity has important effects on photometric color. Considering an important application, we emphasize the possible role of the porosity of the cometary dust particles on polarization and color of the light scattered by cometary coma.

description: We present the prototype telescope for the Next Generation Transit Survey, which was built in the UK in 2008/09 and tested on La Palma in the Canary Islands in 2010. The goals for the prototype system were severalfold: to determine the level of systematic noise in an NGTS-like system; demonstrate that we can perform photometry at the (sub) millimagnitude level on transit timescales across a wide field; show that it is possible to detect transiting super-Earth and Neptune-sized exoplanets and prove the technical feasibility of the proposed planet survey. We tested the system for around 100 nights and met each of the goals above. Several key areas for improvement were highlighted during the prototyping phase. They have been subsequently addressed in the final NGTS facility which was recently commissioned at ESO Cerro Paranal, Chile.

Electrostatics in dissipative particle dynamics using Ewald sums with point charges

description: A proper treatment of electrostatic interactions is crucial for the accurate calculation of forces in computer simulations. Electrostatic interactions are typically modeled using Ewald based methods, which have become one of the cornerstones upon which many other methods for the numerical computation of electrostatic interactions are based. However, their use with charge distributions rather than point charges requires the inclusion of ansatz for the solutions of the Poisson equation, since there is no exact solution known for smeared out charges. The interest for incorporating electrostatic interactions at the scales of length and time that are relevant for the study the physics of soft condensed matter has increased considerably. Using mesoscale simulation techniques, such as dissipative particle dynamics (DPD), allows us to reach longer time scales in numerical simulations, without abandoning the particulate description of the problem. The main problem with incorporating electrostatics into DPD simulations is that DPD particles are soft and those particles with opposite charge can form artificial clusters of ions. Here we show that one can incorporate the electrostatic interactions through Ewald sums with point charges in DPD if larger values of coarse graining degree are used, where DPD is truly mesoscopic. Using point charges with larger excluded volume interactions the artificial formation of ionic pairs with point charges can be avoided, and one obtains correct predictions. We establish ranges of parameters useful for detecting boundaries where artificial formation of ionic pairs occurs. Lastly, using point charges we predict the scaling properties of polyelectrolytes in solvents of varying quality and obtain predictions that are in agreement with calculations that use other methods, and with recent experimental results.
