Pulsation in pre-main sequence stars: TESS observations & models from accreting protostars T. Steindl , K. Zwintz , T. G. Barnes , M. Müllner , E. I.

Initial models are created with huge radii and uniform contraction to make them fully convective. These then follow the classical pre-main sequence evolution starting with a fully convective contraction along the Hayashi track. Only after the onset of thermal reaction slows the contraction will the star develope a radiative core that will continue to grow while the star evolves along the Henyey track. Before arriving at the main sequence, a ﬁrst episode of hydrogen burning leads to a convective core and pauses the contraction, resulting in the well known hook in the evolutionary track. Show model details This however is far from the real processes that happen in and around newly born stars. Born in the collapse of a molecular cloud, protostellar seeds typically have a few Jupiter masses at a few solar radii. A main difference to the classical pre-main sequence evolution is that these protostellar seeds need to accrete material from their surrounding cloud/disk to obtain the same mass at the zero age main sequence. Such accreting protostars never obtain the huge radii adopted for the classical initial models. As a consequence, the evolutionary track is completely altered. The model starts at signiﬁcantly lower temperatures and accretes material at a constant rate. The initially fully convective star quickly obtains a radiative part between the convective core and the convective envelope. Only during the short phase of deuterium burning will (almost) the whole star be convective again. After the model has accreted all its mass, it converges to the classical model. 1 1 2 1 3,4 1 2 3 4 0:00 / 0:20 Thomas Steindl Home Publications Physics CV https://thomassteindl.com/poster/TESS_Science_Conference_II_2021
New generation offline software for the LHCb upgrade I Martina Ferrillo*† Universität Zürich, Winterthurerstrasse 190, CH-8057 Zürich E-mail: martina.ferrillo@cern.ch In preparation for Run 3 of the LHC, the LHCb experiment extensively upgrades its detector to meet the quest for higher luminosity and physics yield. The corresponding increase in the data volume and the use of fast simulation pose a challenge to the data storage resource strategy and computing model. The newly built Data Processing & Analysis Tools (DPA) project aims at coordinating the efforts in the development of the experiment software offline tools to ensure efficient and full exploitation of the LHCb physics potential. This work presents an overview of the main aspects of the new generation software developed within the DPA: the offline data processing strategy; the mechanisms for user data-structures production; the offline user analysis tools. ***Presented at the 30th International Symposium on Lepton Photon Interactions at High Energies,*** *** hosted by the University of Manchester,*** *** 10-14 January 2022.*** *Speaker. †On behalf of the LHCb Collaboration. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0). http://pos.sissa.it/

— 622 632 Celebration & Contemplation, 10th International Conference on Design & Emotion 27 — 30 September 2016, Amsterdam Abstract The Auto-Cam investigates how design researchers can take advantage of photography as a visual research method through the design and deployment of a wearable ‘POV’ (Point-Of-View) camera. Photographs have a unique ability to capture and express personal perspective and promote empathy among researchers and participants (Van Gestel, 2015), but photography remains relatively overlooked as a research method, in particular for design research. The Auto-Cam provides a first-person look into someone’s daily life and activities, using coloured stickers as a way to ‘tag’ objects of interest in one’s environment; the Auto-Cam is designed to automatically capture an image when it ‘sees’ a sticker. We present the Auto-Cam as a case study showing the value of automated first-person photography and the importance of continuing to explore the potential of photography as a valuable research method for design.

It’s perhaps no surprise that photography is particularly well-suited as a visual research method – photographs can provide deep qualitative insight, serve as artistic or design inspiration, and be revisited for ongoing reflection. Photography has traction as a visual research method across the social sciences, but there is still relatively little critical inquiry into how we can capture and analyse photographs as design researchers. More recently discourse around visual research within design has grown; for example, questioning how photography can be used within HCI design in particular (Bariola and Faste, 2012). For example, snapshots like the three above taken during fieldwork for design research are valuable research material, able to inspire design informed by observed experiences. How could this woman’s experience of boarding a train be more seamless, more dignified? How could we design a service for handicapped passengers that doesn’t disrupt the flow of passenger traffic?

En el siguiente trabajo proponemos realizar un estudio desde la memoria territorial, intentando reconocer aquellos lugares donde el terrorismo de Estado actuó. El Municipio de La Matanza, ubicado en la Provincia de Buenos Aires, al igual que el resto de la Argentina fue escenario del horror y la violencia sistemática. Tanto el espacio público como el privado fueron testigos mudos de la acción violenta ejercida sobre la población. Con el deseo de activar la memoria, en los últimos años distintos lugares significativos fueron ‘marcados’ por la intervención política y voluntaria. En esta presentación atenderemos a aquellas marcas urbanas realizadas para recordar a las víctimas en el territorio matancero, identificando sus formas y los procesos de producción. Enfatizaremos en un estudio de caso: las aparecidas en recuerdo del concejal y literato Delfor Santos Soto, detenido desaparecido el 21 de agosto de 1976 en la localidad de Ramos Mejía. Utilizaremos como fuentes primarias los libros publicados de su autoría, entrevistas realizadas a su esposa e hija, diarios de sesiones, y observaciones y relevamientos realizados sobre la geografía matancera para identificar las marcas en su nombre diseminadas en el espacio. ¿Por qué nos detenemos en un estudio de caso? Porque de esta manera podremos trabajar desde la categoría de ‘memoria ejemplar’. Nos situamos más allá del acontecimiento, no negando su singularidad, pero permitiéndonos usarlo como modelo para pensar y abordar otros. Las marcas de la memoria en el Partido de La Matanza. Antes de continuar debemos caracterizar territorialmente al Partido de La Matanza entre
Overview. Pollution is an ever increasing problem in modern society. Much of this pollution is anthropogenic (man made) in origin. Sulphur dioxide (SO2) , hydrocarbons (VOC), carbon monoxide (CO) and oxides of nitrogen (NOX) are largely anthropogenic. Many of these compounds can greatly affect rural areas. Pollutants are released from cities and industrial areas. Over many miles, reactions can alter the chemical composition of this pollution.
Probing a GeV-scale Scalar Boson in Association with a TeV-scale Vector-like Quark in the U(1)T3R BSM Extension at the LHC using Machine Learning Alfredo Gurrola, Umar Sohail Qureshi Department of Physics and Astronomy, Vanderbilt University 17-21 July 2023 Abstract A U(1)T 3R extension of the Standard Model (SM) can address the mass hier- archy between the third and the first two generations of fermions, explain thermal dark matter abundance, and the muon g −2 and B-meson anomalies. The model contains a light scalar boson, the ϕ′ and a heavy vector-like quark χu that can be probed from proton-proton (pp) collisions at CERN’s Large Hadron Collider (LHC) at √s = 13 TeV through g−g and χu−t fusion. We work under a phenomeno- logical framework in which the χu and ϕ′ masses are free parameters and develop a discovery methodology considering final states of the χu decaying to a b-quark, a muon, and MET from neutrinos and the ϕ′ decaying to µ+µ−. The analysis is performed using machine learning algorithms, over traditional methods, to maxi- mize the signal sensitivity with an integrated luminosity of 3000 fb−1. Further, we note the proposed methodology can be a key mode for discovery over a large mass range, including low masses, traditionally considered difficult due to experimental constraints.

VALIDAÇÃO DE ONTOLOGIA SOBRE FINANÇAS DESCENTRALIZADAS E SUA CONTRIBUIÇÃO NO PROCESSO DE LETRAMENTO FINANCEIRO-DIGITAL VALIDATION OF ONTOLOGY ON DECENTRALIZED FINANCE AND ITS CONTRIBUTION IN THE DIGITAL FINANCIAL LITERACY PROCESS DOI: https://doi.org/10.5281/zenodo.11372520 1 INTRODUÇÃO As ontologias são artefatos de representação e organização do conhecimento, capazes de descrever uma realidade, constituída de um vocabulário e os fatos que o embasam (Guarino, 1998 apud Almeida; Bax, 2003). São cada vez mais utilizadas para representar domínios ou áreas de conhecimento e apresentam a capacidade de inferência automática baseada em lógicas. Sistemas de Finanças Descentralizadas (DeFi) replicam serviços e instrumentos financeiros tradicionais, ao mesmo tempo que eliminam as instituições centralizadoras dos processos (Gramlich et al., 2023, p. 1). As transações são baseadas em redes blockchain: Blockchain pode ser considerada um tipo de arquitetura distribuída de banco de dados em que uma rede descentralizada de partes interessadas mantém uma máquina de estados única. [...] As transações em blockchain são disseminadas entre os seus participantes em blocos de dados, cuja segurança e confiabilidade é garantida por criptografia. (Cossenzo; Bax; Costa, 2024, p. 2). Esta pesquisa visa o processo de validação de uma ontologia sobre DeFi, com apoio de especialistas de domínio e outros usuários. Com isso espera-se investigar o potencial da ontologia como instrumento de letramento financeiro-digital para uma melhor compreensão dos

QM/MM Simulation Hybrid quantum mechanics/molecular mechanics (QM/MM) simulations have become a popular tool for investigating chemical reactions in condensed phases. In QM/MM methods, the region of the system in which the chemical process takes place is treated at an appropriate level of quantum chemistry theory, while the remainder is described by a molecular mechanics force field. Within this approach, chemical reactivity can be studied in large systems, such as enzymes. Using quality management to calculate the properties of a large chemical library is time-consuming and costly. High-precision QM/MM calculation is a multi-scale calculation method to study ligand binding. By using quantum chemistry representing ligands combined with molecular mechanics to characterize proteins and solvents, modeling time can be greatly reduced. Our bioinformaticians will provide you the most efficient quantum chemistry services. Figure 1. Illustration of the QM/MM concept. A small region, in which a chemical reaction occurs and therefore cannot be described with a force field, is treated at a sufficiently high level of QM theory. The remainder of the system is modelled at the MM level. Overall solutions • Subtractive QM/MM Coupling In the subtractive scheme, the QM/MM energy of the system is obtained in three steps. First, the energy of the total system, consisting of both QM and MM regions, is evaluated at the MM level. The QM energy of the isolated QM subsystem is added in the second step. Third, the MM energy of the QM subsystem is computed and subtracted. The last step corrects for including the
Recent results in the 𝑯→𝑾𝑾channel with full LHC Run-II data collected by the CMS experiment Presented at the 30th International Symposium on Lepton Photon Interactions at High Energies, hosted by the University of Manchester, 10-14 January 2022. Amandeep Kaur𝑎 on behalf of the CMS Collaboration 𝑎Panjab University Chandigarh, India email: a.kaur@cern.ch, kauraman.pu@gmail.com Abstract There are several production channels of the Higgs boson and we are searching for the production of the Higgs boson in association with a vector boson in the 𝐻→𝑊𝑊decay channel with the CMS experiment at the LHC. This measurement provides a direct probe of the Higgs boson coupling to vector bosons. The latest CMS results on the Higgs boson decay to a W boson pair are presented. The focus of the report is on the inclusive and STXS measurements performed for the 𝑉𝐻leptonic channel with full Run 2 data which corresponds to an integrated luminosity of 137 fb−1, collected by the CMS detector at LHC. 1 Introduction This report presents a measurement of the Higgs boson [1, 2] production cross section decaying to 𝑊𝑊 boson in association with 𝑊or 𝑍(collectively 𝑉) boson, and thus referred to as 𝑉𝐻leptonic production. As the Higgs boson mass is smaller than twice the nominal mass of 𝑊boson, at least one of the 𝑊bosons is produced off-shell. This characteristic, along with the small branching ratios for the 𝑉𝐻leptonic production and 𝐻→𝑊𝑊decay, make this measurement challenging. However, this analysis benefits from the data sample collected during Run-II with the compact muon solenoid (CMS) detector [3] at the large hadron collider (LHC) at a center-of-mass energy of √𝑠= 13 TeV, corresponding to an integrated luminosity of 137 fb−1. 2 Analysis Strategy In this analysis the events where associated vector bosos (𝑊or 𝑍) is decaying leptonically are considered. Broadly, the analysis is subdivided into four channels based on the number of leptons and jets: 𝑊𝐻𝑆𝑆, 𝑊𝐻3ℓ, 𝑍𝐻3ℓand 𝑍𝐻4ℓ. The production cross section, which is extracted as a signal strength modifier, are also measured using a simplified template cross sections framework [4] (STXS) in addition to inclusive measurement. Since final states with at least 2 leptons (electrons or muons) are studied, a combination of both single and double lepton triggers are used, feynman diagrams of these processes are shown in Figure.1. There are different challenges in each channel depending upon the dominating backgrounds, hence different approaches, and the following sections will focus on the strategies for each channel: • WHSS: The final state contains two leptons, p𝑚𝑖𝑠𝑠 𝑇 , and jets, as this channel targets the 𝑊𝐻→2ℓ2𝜈𝑞𝑞 as shown in Figure.1(a), and in order to reduce the Drell-Yann background two leptons are required to have the same sign. Based on the number of jets in the event and the lepton flavour, the Signal region (SR) events are divided into four categories 1j e𝜇, 1j 𝜇𝜇, 2j e𝜇, 2j 𝜇𝜇. The electron-electron flavor 1

Information Science Trends 2022 - The ASIS&T European Chapter Research Series. 17-19 June 2022 1 Crossing the border between human and non-human in information science Niloofar Solhjoo, PhD candidate, School of Information Management, Victoria University of Wellington Keywords everyday information behaviour, more-than-human, companion animal, research method, multispecies ethnography, posthumanism STRUCTURED ABSTRACT Aim of the contribution Telling untold story of animals whose actions are linked to human everyday information behaviour (e.g., in a multispecies family), this poster aims to outline methods to address the voice and perspective of nonhuman animals in information studies. Value of the contribution In this creative study design information behaviour was seen as an inseparable part of more-than-human cohabitation as humans have learnt to understand, make meaning, or just live with animals in their homes and cities. Dogs and cats, as embodied and minded individuals living their lives entangled with humans, were recognized as the research participants. This poster makes a call for an ‘animal turn’ in information science to find more-than-human ways of doing research and undermine the exclusiveness of the human agents in the study of information experience. Research context Existing Literature of the scarce information research related to keeping and living with companion animals were mostly expanded reports, outside the information field, and were built on a limited view of the objective information (e.g., documents and recorded information), with no attention to internal and subjective information, and overlooking everyday practices and important actors in a multispecies family. The fact that dogs and cats live with humans and are interactively entangled with everyday life is sufficient to justify their inclusion in information behaviour studies. Therefore, this poster shifts away from a theoretical focus on information research about or on animals to research ‘with’ animals.
