Tooth Surface Modification for Helical Gear Pairs considering Mesh Misalignment Tolerance
Shock and Vibration, 2021 Mesh misalignment in mating the gear tooth surface is common and difficult to be determined accurately because of system deformation and bearing clearances, as well as manufacturing and assembly errors.

Long-Term Care at Advanced Ages: The Effect of Spousal Bereavement on Institutional Care Needs. [PDF]
Health EconABSTRACT With populations aging, long‐term care (LTC) needs and costs rise, intensifying the reliance on informal care. Since spouses predominantly provide such care, it is crucial to understand the transition dynamics from widowhood to institutional LTC, which is the main driver of the public LTC costs in most OECD countries.

Autophagy signaling in hypertrophied muscles of diabetic and control rats
FEBS Open Bio, Volume 13, Issue 9, Page 1709-1722, September 2023., 2023 We analyzed autophagy proteins in extensor digitorum longus (EDL) and soleus muscles of control and diabetic rats after 7 days of hypertrophy. Basal autophagy proteins were higher in EDL. Diabetes did not affect the hypertrophy or autophagy in either muscle. Soleus showed increased autophagy signaling after hypertrophy.

Wind Energy, Volume 26, Issue 7, Page 717-740, July 2023., 2023 Abstract This work develops an optimization algorithm for the definition of gear microgeometry modifications (MGM) on a gearbox belonging to an offshore 10‐MW wind turbine. Subsequently, the impact of the gear microgeometry on the performance of gears and bearings is quantified: First, under rated load conditions and, second, accounting for the ...

Association between emphysema and other pulmonary computed tomography patterns in COVID‐19 pneumonia
Journal of Medical Virology, Volume 95, Issue 1, January 2023., 2023 Abstract To evaluate the chest computed tomography (CT) findings of patients with Corona Virus Disease 2019 (COVID‐19) on admission to hospital. And then correlate CT pulmonary infiltrates involvement with the findings of emphysema. We analyzed the different infiltrates of COVID‐19 pneumonia using emphysema as the grade of pneumonia.

BioMed Research International, Volume 2023, Issue 1, 2023., 2023 The prospective, simple randomized study assesses the effect of focused extracorporeal shock wave therapy (f‐ESWT) on pain intensity and calcification size compared to the application of ultrasound physical therapy in treating patients with calcar calcanei. A total of 124 patients diagnosed with calcar calcanei were consecutively included in the study.

Transboundary and Emerging Diseases, Volume 69, Issue 4, Page 1902-1911, July 2022., 2022 Abstract Shiga toxin‐producing E. coli (STEC) are zoonotic foodborne pathogens of outmost importance and interest has been raised in recent years to define the potential zoonotic role of wildlife in STEC infection. This study aimed to estimate prevalence of STEC in free‐ranging red deer (Cervus elaphus) living in areas with different anthropisation ...

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 The electronic reporting system can alleviate the problems in terms of efficiency, content confidentiality, and reporter privacy imposed in the traditional reporting system. Relying on anonymity, the privacy of reporters can be protected, but the authentication of reporters with fake names should also be maintained.

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 Beveloid gears are usually employed to transfer motion of small shaft angle, but the assembly errors or misalignment can affect the gear tooth contact and dynamic performance. A dynamic model and tooth contact analysis model of the intersecting beveloid gear pair are established, the defects of the theoretical tooth surface in the meshing are analyzed,

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 A new dynamic model for a two‐input two‐path split torque transmission system which considers meshing error, time‐varying meshing stiffness, and meshing‐in impact is proposed. Time‐varying meshing stiffness and meshing‐in impact of each gear pair are accurately calculated based on tooth contact analysis and loaded tooth contact analysis.
