A novel fabrication technique for free-hanging homogeneous polymeric cantilever waveguides

We present a novel bonding technique developed for the fabrication of a cantilever-based biosensing system with integrated optical read-out. The read-out mechanism is based on single-mode waveguides fabricated monolithically in SU-8. For optimal operation of the read-out mode, the cantilever waveguides should be homogenous and this bonding technique ensures free-hanging cantilevers that are surrou

Feel-o-metern

En vanlig klocka kan hjälpa till med när och hur länge. Den kan öka lugnet och framförhållningen men den kan också öka hetsen och minska marginalerna. Almanackan kan stödja planering, överblick och tillbakablick. Även den kan både brukas och missbrukas

Oscillator-strengths For Resonance Transitions In Neutral Selenium and Tellurium Derived From Time-resolved Laser Spectroscopy

We have measured radiative lifetimes for selenium and tellurium resonance levels by using short pulse laser excitation in differentially heated resonance cells. We obtained tau(3S1 Se I) = 2.9(5) ns and tau(3S1 Te I) = 3.1(5) ns, which together with branching ratio values given by Ubelis and Berzinsh yield the absorption oscillator strength f(abs)(Se I, 196.0 nm) = 0.074(16) and f(abs)(Te I, 214.3

Tensin2 reduces intracellular phosphatidylinositol 3,4,5-trisphosphate levels at the plasma membrane.

Tensins are proposed cytoskeleton-regulating proteins. However, Tensin2 additionally inhibits Akt signalling and cell survival. Structural modelling of the Tensin2 phosphatase (PTPase) domain revealed an active site-like pocket receptive towards phosphoinositides. Tensin2-expressing HEK293 cells displayed negligible levels of plasma membrane phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P

Selection on space use in a polymorphic lizard

Background: Polymorphism within the same species, population, and sex is an interesting problem for the evolutionary biologist, since differences in fitness between the morphs have to cancel out over evolutionary time, otherwise morphs of lower fitness would become extinct. One way this may be achieved is through the adoption of different morph-specific reproductive strategies, allowing morphs to

Examination of nationalist ideologies via two films from the former Yugoslavia in which the underground plays a major role – Emir Kusturica's Underground and Srdjan Dragojevic's Pretty Village, Pretty Flame.

Health-related factors associated with hospitalization for old people: Comparisons of elderly aged 85 in a population cohort study.

The aim of this population-based study was to (1) describe living conditions and actual health care utilization among 85 year olds; (2) determine factors that affect hospital admissions in this age. The study was conducted on 85-year-old residents in Linköping municipality, Sweden. The data collected included medical records, health care utilization during the preceding 12 months and a postal ques

Nonendocrine Cancers Associated with Benign and Malignant Parathyroid Tumors.

Context: There are limited reliable epidemiological data concerning whether individuals with benign/malignant parathyroid tumor are at an elevated risk of developing nonendocrine malignancies or vice versa. Objective: The objective of the study was to quantify these risks, especially risk of parathyroid tumors after other cancers. Design: This was a population-based retrospective cohort study. Par
