Two-photon excitation in fluorescence polarization receptor-ligand binding assay

Fluorescence polarization is one of the most commonly used homogeneous assay principles in drug discovery for screening of potential lead compounds. In this article, the fluorescence polarization technique is combined with 2-photon excitation of fluorescence. Theoretically, the use of 2-photon excitation of fluorescence increases the volumetric sensitivity and polarization contrast of fluorescence

Challenges and some new directions in channel coding

Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: spatially coupled Low-Density Parity-Check (LDPC) codes, non-binary LDPC codes, and polar coding.

Performance-based costing as decision support for development of discrete part production : Linking performance, production costs and sustainability

Svensk tillverkningsindustri bidrar till ca 16 % (Statistics Sweden 2016) av bruttonationalprodukten och medverkar till att ca 900 000 av landets invånare har en anställning (Produktion2030 2016), vilket gör sektorn till en viktig del av Sveriges välfärdssystem. Forskningen syftar främst till att ge industrin verktyg för att analysera och utvärdera produktion för resurseffektivare och lönsammare tIn today’s global market, the industry is struggling every day to make the “correct decisions”. Decisions concerning production can range from smaller improvements to choice tool or equipment investments to relocation of entire production facilities. Increasing globalization leads to both opportunities and challenges, driving the need for fact-based decision-support including costs to be able to e

Skydd för färg i varumärkesrätten och marknadsrätten

In today's society, companies are struggling to be heard and seen in the ever-increasing amount of information available on the market. A distinctive trademark has therefore become a very important means of communication for businesses. A trademark is often of considerable value in the form of goodwill and corporate image and is seen to communicate consumer attitude. An entire concept is not uI dagens samhälle kämpar företag för att höras och synas i det överflöd av information som finns tillgänglig. Ett särskiljande kännetecken har därmed blivit ett mycket viktigt kommunikationsmedel för företag. I detta kännetecken ligger ofta ett betydande värde i form av goodwill och image och attityd hos förbrukarna. Inte sällan är det hela koncept som förmedlas i ett komplicerat byggande av relat

Multidisciplinary monitoring of an in-situ remediation test of chlorinated solvents

Pollutions on and within the underground poses risks for groundwater contamination and is a widespread global problem. Common remediation methods based on digging and removal can be expensive and have limitations, while in-situ remediation is an attractive alternative. However, there is a need to develop tools to monitor the effectiveness both in terms of the successful injection of remediation fl

Beyond Additivity : A mixture of glucose and NaCl can influence skin hydration more than the individual compounds

The barrier function of the skin mainly relies on its outermost layer, the stratum corneum (SC), which is a lipid-protein composite biomaterial. In addition, SC contains a mixture of small polar compounds, the natural moisturizing factor (NMF). Most of the NMF components are solid at ambient relative humidities (RHs). We herein raise the question of what the effects of adding a mixture of chemical

Polarization effects in Raman spectroscopy of light-absorbing carbon

Raman spectroscopy is widely used for characterization of carbon-based mate- rials including light-absorbing carbonaceous (LAC) matter. However, informa- tion on polarization properties of these materials are generally lacking, and often the polarization characteristics of experiments are not presented in the literature thereby giving uncertainty to presented data. In this work, the polari- zation

Impact of SM parameters and of the vacua of the Higgs potential in gravitational waves detection

In this work we discuss two different phases of a complex singlet extension of the Standard Model (SM) together with an extension that also includes new fermion fields, in particular, a Majoron model equipped with an inverse seesaw mechanism. All considered scenarios contain a global U(1) symmetry and allow for first-order phase transitions while only two of them are strong enough to favour the de

An unexpected advantage of whiteness in horses: the most horsefly-proof horse has a depolarizing white coat

White horses frequently suffer from malign skin cancer and visual deficiencies owing to their high sensitivity to the ultraviolet solar radiation. Furthermore, in the wild, white horses suffer a larger predation risk than dark individuals because they can more easily be detected. In spite of their greater vulnerability, white horses have been highly appreciated for centuries owing to their natural

Modular Polarization-Engineered Optical Phased Arrays for Optical Wireless Indoor Networks

The growing passion for indoor optical wireless networks reflects their immense capability to deliver consistent high-quality data connectivity across diverse indoor environments. This study examines how polarization can be engineered to enhance near-field beam focusing in optical wireless indoor networks using a modular clustered optical phased array aperture. The aperture follows a ceiling-mount

Observations on speech characteristics associated with childhood apraxia of speech in a dynamic motor speech assessment

Bedömning av ett barns talsvårigheter behöver baseras på flera uppgifter och testmetoder för att möjliggöra identifiering av den eller de talproduktionsnivåer som är inblandade. Syftet med studien var att undersöka hur ett benämningstest och ett dynamiskt motoriskt taltest bidrog till observationer av talbeteenden förenliga med brister i talmotorisk planering. Deltagarna var 28 barn mellan tre ochThe assessment of a child’s speech problem should incorporate several tasks and sampling methods to identify the difficulties appointing the speech production level/s involved. This study aimed to investigate how a dynamic motor speech test contributed to a naming test in observing speech characteristics consistent with deficits of speech motor planning. Participants were 28 children, 3 to 9 years

Sound of democracy : Towards the democratisation of standards for soundscapes​

With this audio paper, our aim is to explore the connection between sound and democracy. Recognizing the multifaceted nature of this field, we approach it through the notion of care and an empirical analysis of the democratic implications of trying to regulate sound in public spaces. We examine ISO standards as one example of the many attempts to control sound in both public and private spaces. St

Visualization and understanding of combustion processes using spatially and temporally resolved laser diagnostic techniques

Laser diagnostic techniques have for more than 30 years added very valuable input for a deepened understanding of combustion processes. The present paper will focus on techniques developed for visualization of important parameters with the ability to get detailed information in space and time. The paper is not meant to be a complete review of the entire research field but rather a survey with a ma

Towards Comprehensive Protection of the Marine Environment: Testing the Boundaries of the MARPOL and BASEL Regimes

This thesis discusses the potential conflicts between the MARPOL and BASEL regimes in relation with management of wastes derived from operations of ships. The analysis whether the BASEL Convention provides an overarching regime to deal with waste cycle from generation to disposal is also addressed for determining if MARPOL has to complement this regime. To this end, a holistic view regarding the e

Perspectives on soundscapes : Verb constructions in descriptions of everyday sounds

This study explores how listeners use verb constructions to describe everyday sounds. It considers (i) how the verb constructions provide Gestalt to events in the form of activities, processes and states, and (ii) how the constructions correspond to different aspects of a soundscape (sound sources, acoustic properties, and listener reactions). We found that verb constructions primarily describe so

Political participation on Facebook during Brexit : Does user engagement on media pages stimulate engagement with campaigns?

This study investigates, over an 18-month period surrounding the 2016 Brexit referendum, the commenting activity of nearly 2 million Facebook users engaging with political news from British media or with the posts of referendum campaigns. We ask whether citizens’ engagement with political news on Facebook motivates their participation with political campaign posts, and we examine whether users com
