Gaia-Sausage-Enceladus star formation history as revealed by detailed elemental abundances
H. Ernandes, D. Feuillet, S. Feltzing
et al.
The Gaia-Sausage-Enceladus was the last major merger and central turning point in the Milky Way's story. This event, comparable in mass to the Large Magellanic Cloud today, left behind significant debris that provides valuable insights into the assembly history of our Galaxy and the chemical evolution of dwarf galaxies. By examining the aftermath of the GSE merger, we can delve deeper into understanding how the Milky Way's formation unfolded and how dwarf galaxies evolved chemically. Specifically, the distinct patterns of neutron capture elements such as Eu and Ba, along with Mg, offer clues about the star formation history. Through a comprehensive analysis of data compiled in the SAGA database, we investigated the Gaia Sausage-Enceladus' star formation history. Elemental abundance ratios ([Eu/Mg], [Ba/Mg], and [Eu/Ba]) derived from this study, when compared with those of surviving Milky Way satellites, indicate that the GSE experienced a prolonged period of slow star formation, lasting over 2 Gyr, until it was eventually quenched by merging with the Milky Way. Consequently, these elemental signatures serve as a unique window into the complex history of both surviving and accreted satellites orbiting our Galaxy.

The End of the Journey towards Female Perfection in Smile, by Roddy Doyle
Aída Díaz-Bild
In his novels Roddy Doyle has challenged stereotypes about women by creating strong female characters who are defined by their resilience and determination. In Smile he presents for the first time a beautiful, successful and moneyed woman. Rachel Carey is a TV celebrity and a feminist activist who marries Victor, an underdog. Rachel redeems him and helps him come to terms with the sexual abuse he suffered as a child. But at the end of the novel the reader discovers that this powerful and successful woman never entered into a relationship with Victor. The aim of this paper is to examine how this fictitious wife that Victor has created seems to possess all the best qualities of two of the most interesting female spouses created by Doyle: Miss O’Shea and Aoife Rabbitte.

RLGNet: Repeating-Local-Global History Network for Temporal Knowledge Graph Reasoning
Ao Lv, Guige Ouyang, Yongzhong Huang
et al.
Temporal Knowledge Graph (TKG) reasoning involves predicting future events based on historical information. However, due to the unpredictability of future events, this task is highly challenging. To address this issue, we propose a multi-scale hybrid architecture model based on ensemble learning, called RLGNet (Repeating-Local-Global History Network). Inspired by the application of multi-scale information in other fields, we introduce the concept of multi-scale information into TKG reasoning. Specifically, RLGNet captures and integrates different levels of historical information by combining modules that process information at various scales. The model comprises three modules: the Repeating History Module focuses on identifying repetitive patterns and trends in historical data, the Local History Module captures short-term changes and details, and the Global History Module provides a macro perspective on long-term changes. Additionally, to address the limitations of previous single-architecture models in generalizing across single-step and multi-step reasoning tasks, we adopted architectures based on Recurrent Neural Networks (RNN) and Multi-Layer Perceptrons (MLP) for the Local and Global History Modules, respectively. This hybrid architecture design enables the model to complement both multi-step and single-step reasoning capabilities. Finally, to address the issue of noise in TKGs, we adopt an ensemble learning strategy, combining the predictions of the three modules to reduce the impact of noise on the final prediction results. In the evaluation on six benchmark datasets, our approach generally outperforms existing TKG reasoning models in multi-step and single-step reasoning tasks.
ZIKQ: An innovative centile chart method for utilizing natural history data in rare disease clinical development
Tianying Wang, Wenfei Zhang, Ying Wei
Utilizing natural history data as external control plays an important role in the clinical development of rare diseases, since placebo groups in double-blind randomization trials may not be available due to ethical reasons and low disease prevalence. This article proposed an innovative approach for utilizing natural history data to support rare disease clinical development by constructing reference centile charts. Due to the deterioration nature of certain rare diseases, the distributions of clinical endpoints can be age-dependent and have an absorbing state of zero, which can result in censored natural history data. Existing methods of reference centile charts can not be directly used in the censored natural history data. Therefore, we propose a new calibrated zero-inflated kernel quantile (ZIKQ) estimation to construct reference centile charts from censored natural history data. Using the application to Duchenne Muscular Dystrophy drug development, we demonstrate that the reference centile charts using the ZIKQ method can be implemented to evaluate treatment efficacy and facilitate a more targeted patient enrollment in rare disease clinical development.
La fabrique de la violence : les pratiques de torture lors de l’opération Demetrius comme tournant du conflit nord-irlandais
Louise Gerbier
This article analyses the mechanisms behind the surge of violence in the years 1971-1972 during the Northern Irish conflict. It shows how the choice to use internment and the authorisation to use five techniques that amount to torture in the context of the so-called “interrogation in depth” coincide with both an increase in violence and the entrenchment of antagonisms. After looking at the security reasoning justifying these decisions, the article focuses on the experience of violence by republican detainees, and finally maps the normalisation of violence and of repressive apparatuses in Northern Ireland through the political and judicial reactions to this episode.

Kicking Back: Negation of Enlightenment in Brian Dillon’s Objects in This Mirror
ALFRED MARKEY
In this article I will examine aspects of the work of the Irish writer Brian Dillon which allow us to propose the continuing relevance, from an Irish perspective, of a strain of critical discourse which engages with the legacy of the Enlightenment. Specifically, I look primarily at Dillon’s 2014 essay collection Objects in This Mirror as well as his 2017 collection Essayism, with a view to establishing some key characteristics of his artistic project, while showing their compatibility with the cultural materialism of key scholars of the Frankfurt School, before finally making explicit the compatibility of Dillon’s work with the values which underpin the Irish Field Day project which has influenced Irish studies since the 1980s.

Consistency test of the fine-structure constant from the whole ionization history
Ke Wang, Lu Chen
In cosmology, the fine-structure constant can affect the whole ionization history. However, the previous works confine themselves to the recombination epoch and give various strong constraints on the fine-structure constant. In this paper, we also take the reionization epoch into consideration and do a consistency test of the fine-structure constant from the whole ionization history. From the data combination of Planck 2018, BAO data, SNIa samples, SFR density from UV and IR measurements, and the $Q_\text{HII}$ constraints, we find the constraint on the fine-structure constant during the recombination epoch is $α_{\text{rec}}/α_{\text{EM}}=1.001494^{+0.002041}_{-0.002063}$ and its counterpart during the reionization epoch is $α_{\text{rei}}/α_{\text{EM}}=0.854034^{+0.031678}_{-0.027209}$ at 68$\%$ C.L.. They are not consistent with each other by $4.64σ$. A conservative explanation for such a discrepancy is that there are some issues in the data we used. We prefer a calibration of some important parameters involved in reconstructing the reionization history.
‘Woman Suffrage Precipice’: The Gender Politics of Laughter in Elizabeth Robins’s The Convert (1907)
Nathalie Saudo-Welby
An actress turned playwright and political militant, Elizabeth Robins was aware of the political uses of laughter. Her novel The Convert, in which laughter is explicitly linked to performance and action, is stimulating material for an investigation of the part played by humour in women’s empowerment. The New Woman was often criticized for her lack of humour, and gravity was the expected context of feminist novels with a purpose. Elizabeth Robins wanted her political drama Votes for Women to “deal with the Suffrage question for the first time in a serious fashion”. Yet, when the play was transformed into a novel, The Convert, comedy became a central element in the representation of female suffrage. Indeed, since the New Woman was commonly a target for caricature, the suffragette a laughing stock, and feminist demonstrations were considered as enjoyable as “good Sunday afternoon street entertainment”, The Convert turned this tendency to its advantage and used humour as a sweetener for the serious pill it contains, in accordance with the received idea that women are born entertainers. In the witty drawing-room conversations and in the sarcastic call and response exchanges during the demonstration scenes, Elizabeth Robins also builds up a reflection on the gender politics of humour. Her didactic novel indicates that not all laughter is “good to hear” and that feminist literature must bring some laughs to a halt. More crucially, it suggests that while men laugh, women may learn. The loudness of the laughing response is proportionate to the gravity and magnitude of the woman question. In the course of her conversion into a suffragette, Vida gets a sense of her political significance, builds up her armour and turns her sense of repartee into a political weapon.
Polynomial expansion of the star formation history in galaxies
D. Jiménez-López, P. Corcho-Caballero, S. Zamora
et al.
Context. There are typically two different approaches to inferring the mass formation history (MFH) of a given galaxy from its luminosity in different bands. Non-parametric methods are known for their flexibility and accuracy, while parametric models are more computationally efficient. Aims. In this work we propose an alternative, based on a polynomial expansion around the present time, that combines the advantages of both techniques. Methods. In our approach, the MFH is decomposed through an orthonormal basis of N polynomials in lookback time. To test the proposed framework, synthetic observations are generated from models based on common analytical approximations (exponential, delayed-$τ$, and Gaussian star formation histories), as well as cosmological simulations for the Illustris-TNG suite. A normalized distance is used to measure the quality of the fit, and the input MFH is compared with the polynomial reconstructions both at the present time and through cosmic evolution. Our polynomial expansion is also compared with widely used parametric and non-parametric methods such as CIGALE anda PROSPECTOR. Results. The observed luminosities are reproduced with an accuracy of around 10 per cent for a constant star formation rate (N=1) and better for higher-order polynomials. Our method provides good results on the reconstruction of the total stellar mass, the star formation rate, and even its first derivative for smooth star formation histories, but it has difficulties in reproducing variations on short timescales and/or star formation histories that peak at the earliest times of the Universe. Conclusions. The polynomial expansion appears to be a promising alternative to other analytical functions used in parametric methods, combining both speed and flexibility.

Radial Star Formation Histories in 32 Nearby Galaxies
Daniel A. Dale, Kristin R. Anderson, Louis M. Bran
et al.
The spatially resolved star formation histories are studied for 32 normal star-forming galaxies drawn from the the Spitzer Extended Disk Galaxy Exploration Science survey. At surface brightness sensitivities fainter than 28 mag arcsec$^{-2}$, the new optical photometry is deep enough to complement archival ultraviolet and infrared imaging and to explore the properties of the emission well beyond the traditional optical extents of these nearby galaxies. Fits to the spectral energy distributions using a delayed star formation history model indicate a subtle but interesting average radial trend for the spiral galaxies: the inner stellar systems decrease in age with increasing radius, consistent with inside-out disk formation, but the trend reverses in the outermost regions with the stellar age nearly as old as the innermost stars. These results suggest an old stellar outer disk population formed through radial migration and/or the cumulative history of minor mergers and accretions of satellite dwarf galaxies. The subset of S0 galaxies studied here show the opposite trend compared to what is inferred for spirals: characteristic stellar ages that are increasingly older with radius for the inner portions of the galaxies, and increasingly younger stellar ages for the outer portions. This result suggests that either S0 galaxies are not well modeled by a delayed-$τ$ model, and/or that S0 galaxies have a more complicated formation history than spiral galaxies.
Gravitational waves from binary black holes as probes of the structure formation history
Tomohiro Nakama
Gravitational-wave detectors on earth have detected gravitational waves from merging compact objects in the local Universe. In future we will detect gravitational waves from higher-redshift sources, which trace the high-redshift structure formation history. That is, by observing high-redshift gravitational-wave events we will be able to probe structure formation history. This will provide additional insight into the early Universe when primordial fluctuations are generated and also into the nature of dark matter.
Great Britain, the Soviet Union and the resistance movements in Yugoslavia, 1941
Nikolić Kosta
During the Second World War a brutal and distinctly complex war was fought in
Yugoslavia. It was a mixture of an anti-fascist struggle for liberation as
well as an ideological, civil, inter-ethnic and religious war, which
witnessed a holocaust and genocide against Jews and Serbs. At least a
million Yugoslavs died in that war, most of them ethnic Serbs. In their
policies towards Yugoslavia, each of the three Allied Powers (the United
States of America, the Soviet Union and Great Britain) had their short-term
and long-term goals. The short-term goals were victory over the Axis powers.
The long-term goals were related to the post-war order in Europe (and the
world). The Allies were unanimous about the short-term goals, but differed
with respect to long-term goals. The relations between Great Britain and the
Soviet Union were especially sensitive: both countries wanted to use a
victory in the war as a means of increasing their political power and
influence. Yugoslavia was a useful buffer zone between British and Soviet
ambitions, as well as being the territory in which the resistance to the
Axis was the strongest. The relations between London and Moscow grew even
more complicated when the two local resistance movements clashed over their
opposing ideologies: nationalism versus communism. The foremost objective of
the Communist Party of Yugoslavia (CPY) was to effect a violent change to
the pre-war legal and political order of the Kingdom of Yugoslavia. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. 177016:

Digitory, A Smart Way of Learning Islamic History in Digital Era
Dimas Agil Marenda, Ahmad Nasikun, Canggih Puspo Wibowo
In this paper, we would like to propose our web-based application for Islamic history learning system, named Digitory-Digital History. There are two main navigations to browse historical stories on the web. One is location-based navigation using on-line map which gives users access to understand events during Islamic introduction to Indonesia based on the location. Alternatively, users can browse on time base using sliding navigation marked timely, so they can comprehend history in time sequence. Implementing semantic web, this web-app can suggest users related articles, either based on time series, location similarities, or time-domain similarities, and also suggest pictures related to the articles. AJAX strengthen the real-time access and interactivity as users navigate around the web. By the end of this research, we will have the web-app prototype completed with its fundamental location-based navigation, semantic relationship among articles and pictures, and time- based navigation system. As the web-app deployed, we have some volunteers to try our application so that we can evaluate its result, particularly its effectiveness.
