    Insomnia Severity Predicts Psychiatric Symptoms: a Cross-Sectional Study Investigating the Partial Mediations of Worry and Rumination
    (Routledge Journals, Taylor & Francis Ltd, 2024) Turkarslan, Kutlu Kagan; Cinarbas, Deniz Canel
    Objective: Insomnia as a disorder on its own or as a symptom of other mental disorders can lead to significant distress and lower quality of life. By exacerbating negative affect and emotion dysregulation, poor sleep and insomnia can contribute to the initiation and maintenance of mental disorders. The aim of this cross-sectional study was to investigate the relationship between insomnia severity and overall psychiatric symptoms (anxiety, depression, obsessive-compulsive symptoms, somatization, phobic anxiety, hostility, interpersonal sensitivity, paranoid ideation, and psychoticism), and the mediational roles of worry and rumination in this relationship. Method: The data was collected from a community sample of 1444 participants (females 69.39%, M-age=27.95, SD=9.37) who completed self-report measures of insomnia severity, worry, rumination, and psychiatric symptoms. The mediational roles of worry and rumination were tested with mediation analysis using the PROCESS Macro. Results: It was found that insomnia severity (beta=0.20, p<.001) significantly predicted psychiatric symptoms directly and via worry and rumination (beta=0.33, p<.001), meaning that worry and rumination partially mediated the relationship between insomnia severity and psychiatric symptoms. The findings were similar after controlling for smoking status, daily screen time, coffee consumption in the evening, weekly exercise frequency, and pre-sleep screen time. Conclusions: Interventions targeting the reduction of insomnia severity and maladaptive emotion regulation strategies (e.g., worry and rumination), as well as the enhancement of adaptive emotion regulation strategies (e.g., positive refocusing and mindfulness), may alleviate the adverse effects of insomnia on psychiatric symptoms.

    A New Class of Generalized Contraction Using p-functions in Ordered Metric Spaces
    (Sciendo, 2015) Amor, Sana Hadj; Karapinar, Erdal; Kumam, Poom
    In this paper, we introduced and studied a new class of mappings in ordered metric spaces that is inspired from the concept of a P-function introduced in Chaipunya et. al. [10]. With our new class, we furnish fixed point theorems for continuous, noncontinuous, monotonic, and nonmonotonic mappings in various kinds of the ordering structures.

    Object-Oriented Inheritance Metrics: Cognitive Complexity Perspective
    (Springer-verlag Berlin, 2009) Mishra, Deepti; Mishra, Alok
    Identifying high cognitive complexity modules can lead to a better quality software system and can help during maintenance also. It has been found that inheritance has an impact on cognitive complexity of a software system. In this paper, two inheritance metrics based on cognitive complexity, one at class level CCI (Class Complexity due to Inheritance) and another at program level ACI (Average Complexity of a program due to Inheritance), have been proposed for object-oriented software systems. These metrics are also compared with other well known object-oriented inheritance metrics.

    Target Tracking Using Artificial Potentials and Sliding Mode Control
    (2004) Gazi,V.; Ordóñez,R.
    In this article we develop an algorithm for capturing/intercepting a moving target based on the sliding mode control method. First, we consider a "kinematic" model (in a sense) for the capture/intercept problem and develop a method for that case. Then, we build on the developed method to include general fully actuated vehicle dynamics for the pursuer agent. The algorithm is robust with respect to the system uncertainties and additive disturbances. Finally, we also provide a numerical simulation in order to illustrate the procedure.

    Software Architecture in Distributed Software Development: a Review
    (Springer-verlag Berlin, 2013) Mishra, Alok; Mishra, Deepti
    This paper presents a literature review of distributed software development (DSD) or global software development (GSD) and software architecture. The main focus is to highlight the current researches, observations, as well as practice directions in these areas. The results have been limited to peer-reviewed conference papers and journal articles, and analysis reports that major studies have been performed in software architecture and global software development, while the empirical studies of interfacing distributed/global software development and software architecture has only received very little attention among researchers up to now. This indicates the need for future research in these areas.

    Keggin Type-Polyoxometalate Decorated Ruthenium Nanoparticles: Highly Active and Selective Nanocatalyst for the Oxidation of Veratryl Alcohol as a Lignin Model Compound
    (Wiley-v C H verlag Gmbh, 2017) Baguc, Ismail Burak; Saglam, Serif; Ertas, Ilknur Efecan; Keles, Muhammed Nuri; Celebi, Metin; Kaya, Murat; Zahmakiran, Mehmet
    Described herein is a new nanocatalyst system that efficiently works in the aerobic oxidation of veratryl alcohol (VA), which is formed by cleavage of beta-O-4 linkages in lignin, to veratraldehyde (VAL) under mild reaction conditions. The new nanocatalyst system comprised of ruthenium(0) nanoparticles supported on the Keggin type polyoxometalate (POM; K-3[PMo12O40]) network (Ru/POM) can simply and reproducibly be prepared by the dimethylamine-borane ((CH3)(2)NHBH3) reduction of ruthenium(III) chloride trihydrate (RuCl3.3H(2)O) in isopropanol solution of K-3[P Mo12O40] at room temperature. The characterization of Ru/POM by the combination of various analytical techniques reveals that the formation of well-dispersed ruthenium(0) nanoparticles with a mean diameter of 4.7 +/- 1.2nm on the surface of POM network structure. This new Ru/POM nanocatalyst displays remarkable activity (TOF=7.5mol VAld/mol Ru x h) at high selectivity (> 98%) and almost complete conversion (98%) in the aerobic oxidation of VA to VAld under mild conditions.

    Micro-Wedm of Ni55.8ti Shape Memory Superalloy: Experimental Investigation and Optimisation
    (Inderscience Publishers, 2021) Meshri,H.A.M.; Akar,S.; Seyedzavvar,M.; Kiliç,S.E.
    Nickel-titanium superalloy has gained significant acceptance for engineering applications as orthotropic implants, orthodontic devices, automatic actuators, etc. Considering the unique properties of these alloys, such as high hardness, toughness, strain hardening, and development of straininduced martensite, micro-wire electro-discharge machining (μ-WEDM) process has been accepted as one of the main options for cutting intricate shapes of these alloys in micro-scale. This paper presents the results of a comprehensive study to address the material removal rate (MRR) and surface integrity of Ni55.8Ti shape memory superalloy (SMA) in the μ-WEDM process. The effects of discharge current, pulse on-time, pulse off-time, and servo voltage on the performance of this process, including MRR, white layer thickness, surface roughness, and micro-hardness of the machined surface, were investigated by multi-regression analysis using response surface methodology (RSM). The optimisation of input parameters based on the gradient and the swarm optimisation algorithms were also conducted to maximise the MRR and minimise the white layer thickness, surface roughness, and micro-hardness of the machined samples. © 2021 Inderscience Enterprises Ltd..

    Computation of a Tunable Slot-Loaded Equilateral Triangular Microstrip Antenna
    (Vsp Bv, 2009) Aydin, E.
    In this paper, a simple closed form expression is developed to accurately estimate the lower and upper operating frequencies of a single feed slot loaded triangular patch (SLTP) with variations of the bent slot lengths. It is obtained by using cavity model analysis and useful to antenna engineers for accurately predicting both operating resonant frequencies of the SLTP. The theory is compared with the experimental results available in the literature, and excellent agreement is observed. The proposed computation is also extended to the analysis of tunability of the SLTP as a function of the air-gap height.

    Installation and Performance of the 3rd Veto Plane at the SND@LHC Detector
    (IOP Publishing Ltd, 2025) Abbaneo, D.; Acampora, G.; Ahmad, S.; Albanese, R.; Alexandrov, A.; Alicante, F.; Zamora Saa, J.
    During 2022/2023 the optimal inefficiency of the Veto system of the SND@LHC detector was measured to be (7.8 +/- 2.8) x 10(-8). To reduce this inefficiency, a third Veto plane was installed during the 2023-2024 Year End Technical Stop. In addition, the Veto system was lowered to cover the target fully, thereby increasing acceptance. This paper describes how the inefficiency of the Veto system was reduced from (7.8 +/- 2.8) x 10(-8) with an acceptance of about 64% of the target area in 2022-2023 to (4.9 +/- 1.9) x 10(-9) on the full area in 2024.
