Kinematics and trajectory of both-sides cylindrical lapping process in planetary motion type

Julong Yuan, Weifeng Yao, Ping Zhao, Binghai Lyu, more

International Journal of Machine Tools and Manufacture > 2015 > 92 > Complete > 60-71

The both-sides lapping process in planetary motion type is proposed in this paper to lap and polish the cylindrical surface of bearing roller. The rolling speed of roller is the key kinematical parameter that affects the generation of cylindrical surface of roller. Through analysis of friction forces and pure rolling motion, it was discovered that the rolling speed of roller only depends on the rotation...

How baseline, new-onset, and persistent depressive symptoms are associated with cardiovascular and non-cardiovascular mortality in incident patients on chronic dialysis

Sandra van Dijk, Tessa O. van den Beukel, Adrian A. Kaptein, Adriaan Honig, more

Journal of Psychosomatic Research > 2013 > 74 > 6 > 511-517

Objective: Depressive symptoms are associated with mortality among patients on chronic dialysis therapy. It is currently unknown how different courses of depressive symptoms are associated with both cardiovascular and non-cardiovascular mortality. Methods: In a Dutch prospective nation-wide cohort study among incident patients on chronic dialysis, 1077 patients completed the Mental Health Inventory,...

A generation of synthesized trajectories of free moving objects for testing a set of continuous spatio‐temporal queries

Sanghyun Lee, Bonghee Hong, Woochan Kim

Concurrency and Computation: Practice and Experience > 34 > 20 > n/a - n/a

Testing vessel surveillance monitoring queries requires synthesized trajectory generation data of free‐moving objects. This article presents a method for generating trajectories of free moving objects with approach, u‐turn, detour, and hover patterns to verify a set of continuous queries expressed in spatiotemporal conditions. We present an algorithm that generates simplified paths, moving patterns,...

Faith See Jia Wen, Irene Teo Eng Ai, Chetna Malhotra, COMPASS Study Group

Psycho‐Oncology > 31 > 7 > 1161 - 1168

Objective Cancer is a significant cause of mortality worldwide. The diagnosis of advanced cancer affects both patients and their family caregivers. Understanding the course of both negative and positive experiences of caregiving provides a more comprehensive understanding of the caregiving experience. The study aims to identify joint trajectories of burden and esteem among family caregivers of patients...

The intersectionality of life course socioeconomic status, race, and cognitive decline: An 18‐year follow‐up

Yue Zeng, Terry Yat Sang Lum, Yu‐Chih Chen

International Journal of Geriatric Psychiatry > 37 > 8 > n/a - n/a

Objectives Studies have documented the impact of childhood socioeconomic status (SES) on cognition. However, research that simultaneously considers SES in varied life stages, the multidimensional mechanisms, and racial differences is relatively understudied. This study examines the intersectionality across age, SES, and race and its impact on cognitive trajectories. Methods Using 8376 respondents...

Hui‐Yu Tsai, Chi‐Jane Wang, Michiyo Mizuno, Rieko Muta, more

Worldviews on Evidence‐Based Nursing > 19 > 3 > 211 - 218

Background Breast cancer is the most common diagnosis and the leading cause of cancer death among women worldwide and ranks first among Asian and Taiwanese women. Cancer‐related fatigue (CRF) affects patients' functioning significantly. Aims The aim of this study was to examine changes in cancer‐related fatigue (CRF) and related factors among women with breast cancer undergoing a single chemotherapy,...

Chengyi Ding, Dara O'Neill, Annie Britton

Addiction > 117 > 7 > 1920 - 1930

Background and Aims Research into alcohol consumption and cardiovascular disease (CVD) patients' prognosis has largely ignored the longitudinal dynamics in drinking behaviour.

Leveraging time series of satellite and aerial images to promote the long‐term monitoring of restored plant communities

Sophie Taddeo, Sebastian Schmidtlein

Applied Vegetation Science > 25 > 2 > n/a - n/a

Aims Ecological restoration is integral to meeting conservation goals in rapidly changing landscapes, but outcomes vary substantially with some projects failing to meet their targets. To understand the causes of this variability, long‐term monitoring of existing projects is critical, but this comes at considerable costs. Current literature counts several studies using time series of satellite images...

C‐reactive protein trajectories and the risk of all cancer types: A prospective cohort study

Tong Liu, Qingsong Zhang, Chunhua Song, Sarah Tan Siyin, more

International Journal of Cancer > 151 > 2 > 297 - 307

A single CRP measurement is insufficient to examine the association of long‐term patterns of CRP concentration with cancer risk. We prospectively examined the relationship between CRP trajectory patterns and new‐onset cancers among 52 276 participants. Latent mixture modeling was used to identify CRP trajectories. Cox proportional hazards regression models were used to evaluate the association between...

Evaluating restoration trajectories using DNA metabarcoding of ground‐dwelling and airborne invertebrates and associated plant communities

Mieke Heyde, Michael Bunce, Kingsley W. Dixon, Kristen Fernandes, more

Molecular Ecology > 31 > 7 > 2172 - 2188

Invertebrates are important for restoration processes as they are key drivers of many landscape‐scale ecosystem functions; including pollination, nutrient cycling and soil formation. However, invertebrates are often overlooked in restoration monitoring because they are highly diverse, poorly described, and time‐consuming to survey, and require increasingly scarce taxonomic expertise to enable identification...

Nurses' experiences of caring for patients during a prolonged critical illness

Claire Minton, Lesley Batten

Nursing in Critical Care > 26 > 6 > 485 - 492

Background The literature regarding nurses' experiences of caring for chronically critically ill (CCI) patients is scant, however, there are subtleties within the literature, identifying nurses are often challenged providing care to this patient group. This can lead to feeling frustrated, lack of control, and distress. Aims and objectives As part of a larger study, this paper reports nurses' experiences...

Catechol‐O‐methyltransferase (COMT) polymorphism predicts rapid gait speed changes in healthy older adults

Briana N. Sprague, Andrea L. Rosso, Xiaonan Zhu, Nicolaas I. Bohnen, more

Journal of the American Geriatrics Society > 69 > 11 > 3194 - 3202

Importance Adapting one's gait speed to external circumstances is critical for safe ambulation. Dopamine (DA), critical for adapting to increased task demands, predicts usual gait speed and may exert a greater role in complex tasks like rapid gait speed. Objective We hypothesized that a genotypic proxy indicator of greater prefrontal DA signaling would predict significantly faster rapid gait. ...

How long do population level field experiments need to be? Utilising data from the 40‐year‐old LTER network

Sarah Cusser, Jackson Helms, Christie A. Bahlai, Nick M. Haddad, more

Ecology Letters > 24 > 5 > 1103 - 1111

We utilise the wealth of data accessible through the 40‐year‐old Long‐Term Ecological Research (LTER) network to ask if aspects of the study environment or taxa alter the duration of research necessary to detect consistent results. To do this, we use a moving‐window algorithm. We limit our analysis to long‐term (> 10 year) press experiments recording organismal abundance. We find that studies conducted...
