Proper mappings and dimension [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
In this note it is shown that if W is the long line and f is a proper mapping of WX [0, 1 ] into Y, then dim Y22. This answers a question raised by Isbell. The main result of this note is that if W is the long line and f is a proper mapping of WX [0, 1) into Y, then dim Y_2. This answers a question posed by Isbell [2, pp. 119-120]. The main result will

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

An Efficient Rescue System with Online Multi-Agent SLAM Framework

open access: yesSensors, 2019
A novel and an efficient rescue system with a multi-agent simultaneous localization and mapping (SLAM) framework is proposed to reduce the rescue time while rescuing the people trapped inside a burning building.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Secant Cylinders Are Evil—A Case Study on the Standard Lines of the Universal Transverse Mercator and Universal Polar Stereographic Projections

open access: yesISPRS International Journal of Geo-Information
The literature usually calls downscaled versions of basic conformal map projections “secant”, referring to conceptual developable map surfaces that intersect the reference frame.

Forest road network planning based on environmental, technical and economical considerations using GIS and AHP (Case study: Baharbon district in Kheyroud forest) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2011
The goal of this study is presenting a proper method to improve the planning of forest roads network based on environmental, technical and economical considerations using GIS (Geographical Information System) and AHP (Analytical Hierarchy Process).
