Search for high-mass W? and Z? resonances using hadronic W/Z boson decays from 139 fb-1 of pp collisions at ?s=13 TeV with the ATLAS detector
Get PDFA search for high-mass charged and neutral bosons decaying to W gamma and Z gamma final states is presented in this paper. The analysis uses a data sample of root s = 13TeV proton-proton collisions with an integrated luminosity of 139 fb(-1) collected by the ATLAS detector during LHC Run 2 operation. The sensitivity of the search is determined using models of the production and decay of spin-1 charged bosons and spin-0/2 neutral bosons. The range of resonance masses explored extends from 1.0TeV to 6.8TeV. At these high resonance masses, it is beneficial to target the hadronic decays of the W and Z bosons because of their large branching fractions. The decay products of the high-momentum W/Z bosons are strongly collimated and boosted-boson tagging techniques are employed to improve the sensitivity. No evidence of a signal above the Standard Model backgrounds is observed, and upper limits on the production cross-sections of these bosons times their branching fractions to W gamma and Z gamma are derived for various boson production models

Evaluation of polymer electrolyte membrane electrolysis by explainable machine learning, optimum classification model, and active learning
No full textIn this work, a database of 789 experimental points extracted from 30 academic publications was used. The primary objective was to use novel machine-learning techniques to investigate how descriptor variables affect current density, power density, and polarization, and to identify rules or pathways that result in high current density, low power density, and low polarization. First, Shapley analysis was done to find and compare the magnitude of the contribution of each variable on current density as well as the positive and negative effects of all the variables. Then, correlation coefficient heat maps were provided to display the existence of any linear relationship between the input and output variables. Additionally, k-nearest neighbor classification (as an optimal model) was able to demonstrate the entire impact of all features on the outputs. Finally, the Bayesian optimization algorithm showed that the optimum performance of polymer electrolyte membrane electrolyzer could be reached with less experimental effort and time than the usual research plan. It was then concluded that machine learning methods can aid in determining the best conditions for designing a polymer electrolyte membrane electrolyzer to produce hydrogen, which can be used to guide the planning of future experiments.

NEIGHBOUR NOISE IN MULTI-STOREY HOUSING WITH POOR SOUND INSULATION-FACTS AND OCCUPANTS' VIEWPOINTS
No full textAMC Mecanocaucho;Bosco Italia Spa;Ecophon Saint-Gobain;et al.;Head Acoustics;Mason Industries, Inc.10th Convention of the European Acoustics Association, EAA 2023 -- 11 September 2023 through 15 September 2023 -- -- 198863Neighbour noise has a significant role in acoustic privacy, protection and indoor environmental quality in residential buildings. Estimation of annoyance due to neighbour noise and concluding dose-response relationships are challenging due to variety in noise characteristics, occupant perceptions and other individual factors such as attitudes against the noise sources. This study uses qualitative analysis to examine complaints, attitudes and viewpoints on neighbour noise. In February 2021, an article was published in a national newspaper (Jyllands-Posten) of Denmark on the topics of implementation of acoustic labelling and sound insulation improvement. The article was also shared as social media posts in newspaper's official account and it received high public interest and several comments. People's reactions were gathered from the Facebook pages and analysed qualitatively. More than 500 comments were received in total, and these were grouped according to agreement/disagreement with classification, noise complaints (noise sources/activities, building definition, exposure timeframe, measures taken) accountable parties, emotions, beliefs and suggested measures and/or actions. © 2023 Ayca Sentop Dumen [email protected] & Birgit Rasmussen [email protected] This is an open-access article distributed under the terms of the Creative Commons Attribution 3.0 Unported License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited
The effect of psychological resilience on post-traumatic growth level in adults experiencing traumatic grief
No full textÖZET: Bu araştırmada birinci amaç, yas yaşantısı olan yetişkin bireylerde psikolojik sağlamlık, travmatik yas ve travma sonrası büyüme arasındaki ilişkilerin incelenmesidir. Araştırmanın ikinci amacı ise çeşitli demografik değişkenler (cinsiyet, çalışma durumu, medeni durum) ile vefat eden kişiye yakınlık, vefat eden kişinin ölüm nedeni, intihar düşüncelerinin varlığı ve psikolojik destek varlığının travma sonrası büyüme ile ilişkisini incelemektir. Örneklem, sevdiği bir yakını vefat eden 276 katılımcıdan oluşmaktadır. Katılımcıların yaşları 20 ile 66 arasında değişmektedir. Çalışmada Demografik Bilgi Formu, Yas Bilgi Alma Formu, Travma Sonrası Büyüme Ölçeği, Yetişkin Psikolojik Sağlamlık Ölçeği ve İki Boyutlu Yas Ölçeği kullanılmıştır. Elde edilen veriler normal dağılım sınırları içinde olduğu için verilerin analizinde parametrik hipotez testleri tercih edilmiştir. Yapılan analiz sonucunda demografik değişkenlerden cinsiyetin travma sonrası büyümeyi yordadığı; çalışma durumu ve medeni durumun ise travma sonrası büyüme düzeyinde anlamlı bir farklılık yaratmadığı bulunmuştur. Araştırma değişkenlerinden yas sürecinde intiharı düşünmenin travma sonrası büyümeyi yordadığı; vefat eden kişiye yakınlık, vefat eden kişinin ölüm nedeni ve kayıptan sonra psikolojik destek almanın ise travma sonrası büyüme düzeyinde anlamlı bir farklılık yaratmadığı bulunmuştur.ABSTRACT: The primary aim of this study is to examine the relationships between psychological resilience, traumatic grief, and post-traumatic growth in adults who have experienced bereavement. The second aim of the study is to examine the relationship between various demographic variables (gender, employment status, marital status) and closeness to the deceased, the cause of death of the deceased, the presence of suicidal thoughts and the presence of psychological support with post-traumatic growth. The sample consists of 276 participants whose loved one passed away. The ages of the participants ranged from 20 to 66. Demographic Information Form, Grief Information Form, Post Traumatic Growth Scale, Adult Resilience Scale and Two-Dimensional Grief Scale were used in the study. Since the data obtained were within the limits of normal distribution, parametric hypothesis tests were preferred in the analysis of the data. As a result of the analysis, gender, one of the demographic variables, predicted post-traumatic growth; It was found that employment status and marital status did not make a significant difference in the level of post-traumatic growth. Among the research variables, thinking about suicide during the grieving process predicts post-traumatic growth; It was found that closeness to the deceased, the cause of death of the deceased, and receiving psychological support after the loss did not make a significant difference in the level of post-traumatic growth.İÇİNDEKİLER

Epidemic Models for Chemical Gel Phase Transformation: Effect of Optical Measurements with Different Wavelengths
No full textIn our previous work we characterized the sol-gel transition of chemical and physical gels in terms of epidemic models which describe the spread of a disease in a society. We have shown that gelation in chemical gels can be represented by the Susceptible-Infected-Recovered (SIR) model, while the gelation mechanism of physical gels can be represented by the Susceptible-Infected-Susceptible (SIS) model. These studies were based on optical measurements at a single wavelength. In the present work we studied the gelation mechanism for chemical gels obtained from experiments that have been carried out with acrylamide (AAm) and N,N0-methylenebis (acrylamide) (Bis) as base materials for chemical gel formation in water and with cross-linker. The transmitted light intensity was measured for various wavelengths from 440 nm to 690 nm during the gelation process. The data are modeled by the epidemic SIR process. The results indicate that the gelation processes obtained from the same Bis and water contents observed at different wavelengths obey different SIR models. This observation is explained by the scattering of light of different wavelengths depending on the sizes of the micro-gels formed
