Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Borel conjecture for the torus and the splitting of surgery sets
环面 Borel猜想 外科手术集 分裂
2023/5/10
The Borel conjecture considers the obstruction from homotopy equivalence to homeomorphism for aspherical manifolds. The torus is the first computed case of Borel conjecture with the idea of splitting ...
A team of chemists led by Carnegie Mellon University’s Rongchao Jin has for the first time conducted site-specific surgery on a nanoparticle. The procedure, which allows for the precise tailoring of n...
The effects of fat loss after bariatric surgery on inflammation, serum hepcidin, and iron absorption: a prospective 6-mo iron stable isotope study
obesity iron deficiency iron absorption hepcidin inflammation stable isotopes
2018/12/14
Background: Iron deficiency is common in obese subjects. This may be due to an increase in serum hepcidin and a decrease in iron absorption from adiposity-related inflammation.

Immune system drives pregnancy complications
2014/3/18
As a fetal surgeon at UC San Francisco, Tippi MacKenzie, MD, has long known that conducting surgery on a fetus to correct a problems such as spina bifida often results in preterm labor and premature b...
Queensland specialists perform 500th deep brain stimulation surgery
deep brain stimulation surgery

Neurologist Professor Peter Silburn and Neurosurgeon Associate Professor Terry Coyne have performed their 500th deep brain stimulation surgery on a 61-year-old woman with Parkinson’s disease.
Seifert fibered surgery on Montesinos knots
Exceptional Dehn surgery hyperbolic knots Montesinos knots
2012/7/11
Exceptional Dehn surgeries on arborescent knots have been classified except for Seifert fibered surgeries on Montesinos knots of length 3. There are infinitely many of them as it is known that 4n+6 an...
Obtaining genus 2 Heegaard splittings from Dehn surgery
genus 2 Heegaard splittings Dehn surgery Geometric Topology
2012/5/9
Let K' be a hyperbolic knot in S^3 and suppose that some Dehn surgery on K' with distance at least 3 from the meridian yields a 3-manifold M of Heegaard genus 2. We show that if M does not contain an ...
Symplectic homology product via Legendrian surgery
Symplectic homology product Legendrian surgery
2011/2/23
This research announcement continues the study of the symplectic homology of Weinstein manifolds undertaken in [2] where the symplectic homology, as a vector space, was expressed in terms of the Legen...
Left-orderable fundamental groups and Dehn surgery
Left-orderable fundamental groups Dehn surgery
2010/12/9
There are various results that frame left-orderability of a group as a geometric property. Indeed, the fundamental group of a 3-manifold is left-orderable whenever the first Betti number is positive; ...
We prove that the mass endomorphism associated to the Dirac operator on a Riemannian manifold is non-zero for generic Riemannian metrics.The proof involves a study of the mass endomorphism under surge...
Variations on Fintushel-Stern Knot Surgery on 4-manifolds
Fintushel-Stern Knot Surgery 4-manifolds
2010/3/1
We discuss some consequences Fintushel-Stern `knot surgery' operation coming from its handlebody description. We give some generalizations of this operation and give a counterexample to their conjectu...
Surgery Diagrams for Contact 3-Manifolds
contact 3-manifold Legendrian link contact surgery spinc structure
2010/2/26
In two previous papers, the two first-named authors introduced a notion of contact r-surgery along Legendrian knots in contact 3-manifolds. They also showed how (at least in principle) to convert any ...
Study of temperature variation in human peripheral region during wound healing process due to plastic surgery
Wound healing Finite element method
2010/9/17
In this paper, investigations are made to analyze the human body temperature during wound healing process due to surgery. Wound is considered after the skin graft. Skin graft is a technique used in pl...

The link between science, medicine and public trust has been much discussed.1 Surgery shared in the public confidence in the efficacy of scientific medicine and the good intentions of its practitioner...
Design for Control：Surgery, Science, and Space at the Royal Victoria Hospital, Montreal, 1893–1956
Royal Victoria Hospital Surgery Science Space
2009/1/5
In this paper we explore the relationship of modern architecture and modern surgery in the twentieth century. Our central argument is that environments designed for surgery in the modern hospital beca...
