A potential biomarker of cognitive impairment: The olfactory dysfunction and its genes expression
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1884-1897, December 2022., 2022 Abstract Objective Accumulation evidence has reported that olfactory impairment may be an essential clinical marker and predictor of mild cognitive impairment or Alzheimer's disease. Method Participants were enrolled in the population‐based, prospective study in Fuxin county, Liaoning province, China between 2019 and 2021.

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 121-130, January 2023., 2023 This study aimed to investigate the impact of the COVID‐19 pandemic on colorectal cancer treatment in Japan, that was not fully understood. The COVID‐19 pandemic has reduced the number of colonoscopies and surgeries for colorectal cancer and hindered the detection of asymptomatic early‐stage cancers.

Reconsidering Schwarzschild's original solution [PDF]
Astron.Nachr. 322 (2001) 137-142, 2001 We analyse the Schwarzschild solution in the context of the historical development of its present use, and explain the invariant definition of a singular surface at the Schwarzschild's radius, that can be applied to the Kerr-Newman solution too.

Distribution of Dark Matter around a Central Body, Pioneer Effect and Fifth Force [PDF]
Astronom. Nachr. 322 (2001) 93, 2001 Within the framework of the Projective Unified Field Theory the distribution of a dark matter gas around a central body is calculated. As a result the well-known formulas of the Newtonian gravitational interaction are altered. This dark matter effect leads to an additional radial force (towards the center) in the equation of motion of a test body ...

Dark Matter and Rotation Curves of Stars in Galaxies [PDF]
Astron. Nachr. 322 (2001) 103, 2001 The dark matter accretion theory (around a central body) of the author on the basis of his 5-dimensional Projective Unified Field Theory (PUFT) is applied to the orbital motion of stars around the center of the Galaxy. The departure of the motion from Newtonian mechanics leads to approximately flat rotation curves being in rough accordance with the ...

Community resilience to crime: A study of the 2011 Brisbane flood
American Journal of Community Psychology, Volume 70, Issue 3-4, Page 379-393, December 2022., 2022 Abstract Understanding and enhancing community resilience is a global priority as societies encounter a rising number of extreme weather events. Given that these events are typically both sudden and unexpected, community resilience is typically examined after the disaster so there can be no before and after comparisons.

Self-adjoint extensions of operators and the teaching of quantum mechanics [PDF]
Am.J.Phys. 69 (2001) 322, 2001 For the example of the infinitely deep well potential, we point out some paradoxes which are solved by a careful analysis of what is a truly self-adjoint operator. We then describe the self-adjoint extensions and their spectra for the momentum and the Hamiltonian operators in different physical situations.

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study
American Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023 Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...

On the stability of compact supermassive objects [PDF]
Astron. Nachr. v. 322, p.143-152, (2001), 2008 Proceeded from the gravitation equations proposed by one of authors it was argued in a previous paper that there can exist supermassive compact configurations of degenerated Fermi-gas without events horizon. In the present paper we consider the stability of these objects by method like the one used in the theory of stellar structure.
