Hur får man datorer att se celler? Svaret på den frågan hade skapat ett otroligt kraftfullt verktyg för forskare, och vi försöker därför i detta arbete, genom mindre modifieringar, att förbättra dagens metoder. För att kunna se celler måste vi veta var de är någonstans, och jag menar inte på ett ungefär, utan om vi har en bild på en cell, exakt vilka pixlar tillhör cellen och vilka gör det inte?To be able to automatically segment cells in microscopic images would give biologist a new tool to gather crucial data in quantities not possible by manual work. This is however not a trivial problem and has proven to be very difficult, especially if the images are in 3D. One of the major challenges is the ability for the methods to generalize beyond the data it has previously been presented with.

One of the core purposes of the Swedish “nämndemannasystem” is to act as representatives of the public in the court systems. The representation aspect of the “nämndemannasystem” has though been declared non-existent or too weak by previous research and the general debate in society, on the ground of its pictorial composition. However, the concept of representation is not that simple as depicted by

As intelligence-led law enforcement becomes more common, criminal networks have adapted and used various methods to disrupt law enforcement’s collection of intelligence. This dynamic has led to non-state actors’ use of counterintelligence as an emerging research field as it's critical to understand how criminal organizations can try to disrupt or neutralize the intelligence cycle This study ai

Between 2014 and 2015 Sweden accepted, by its standards, an unprecedented amount of asylum seekers into the country. The total effect which that had on the country politically and socially may not be fully understood yet but it represented a shifting point in Swedish politics. The image of Sweden as open, tolerant and liberal had been challenged and the political response was a strict tightening o

The field of public diplomacy has become increasingly dependent on the general digitalization in society, and its use of social media platforms as a mean to spread their political message to the general public. Digitalization has made public diplomacy more attainable for the masses, but it has also given states a larger responsibility in which messages they want to convey to the public. This thesi

This dissertation tackles contemporary optimism regarding global income inequality trends from a critical perspective. It looks at the World Bank's influential report on global inequality from 2016, and investigates whether the World Bank's objective notion of themselves is plausible. In the context of the World Bank’s neoliberal ideological roots, the dissertation comes to the conclusion

Blockchain technologies with its promise of transparency and security have during the last decade created quite the political stir. There exists an abundance of information, hype and research regarding blockchains 'disruptive and ‘transformative’ potential concerning every industry from finance to food production. However, there is an absence of scholarly attention given to identifying and ana

The purpose of this thesis is to investigate the European Commission’s role in the ordinary legislative procedure. To do so, the thesis examines the case of the newly negotiated reform of the CAP. The Commission has for many years had legislative powers when reforming the CAP. However, since the signing of the Lisbon Treaty, the Commission has only had the formal power to initiate legislative prop

This study aims to examine how NATO-states overtly responds to cyberattacks committed by the believed Russian government sponsored hacker group Fancy Bear. After the end of the Cold War the regulation and acceptance for different kinds of covert actions changed in turn with the change in global power dynamics. The current digital environment develops new ways in which states can spy, gather inform

Få blir nog förvånade om någon hävdar att beräkningar inom partikelfysik är invecklade. Bara för att beräkna sannolikheten att den enklaste processen vi tar hänsyn till (vilket är när två elektroner krockar och studsar mot varandra) krävs det åtminstone tre-fyra sidor med ren matematik, och svårigheterna växer snabbt ju mer komplexa processer vi arbetar med. För att kunna ha teoretiska värden att The chirality-flow formalism has proven to make amplitude calculations in the Standard Model analytically simple in comparison to previously established formalisms. To test the viability of the chirality-flow formalism for numerical implementations, a Chiral Automized Flow Extension (CAFE) for MadGraph5_aMC@NLO has been developed to compare amplitude evaluation time scaling between the two. CAFE u

Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on la

En studie som undersöker kapitalstrukturen i teknologiska bolag genom att undersöka vilken påverkan olika bestämmande faktorer har på hävstången i dessa bolag. I studien undersöks även vilken av de populära teorierna The pecking order theory och The trade off theory, som bäst kan förklara kapitalstrukturen i teknologiska bolag.

Uppsatsens primära syfte är att besvara vad som avses med begreppet penninglån. Subsidiära frågeställningar som besvaras är när en transaktion innebär en överträdelse av det generella låneförbudet. Låneförbudet innebär i huvudregel att ett aktiebolag inte får lämna penninglån till aktieägare, styrelseledamöter och andra som ingår i ”den förbjudna kretsen”. En stor del i bedömningen av vad som utgöThe primary aim of the paper is to answer what is meant by the concept of money lending. Secondary questions to be answered are when a transaction constitutes a violation of the general prohibition of lending. As a general rule, the prohibition on lending means that a limited liability company may not make loans of money to shareholders, directors and others who are part of the "prohibited ci

Ett nytt lovande alternativ för antibiotika Hudsår är alltid med risk för bakteriell angrepp. När en infektion uppstår står immunförsvaret inför en stor utmaning, då inte sällan motståndaren övervinner flera strider. En av kroppens strategier för kampen med patogener är inflammation. Den i sin tur när blir okontrollerad, kan leda till överdriven reaktion i hela kroppen. Sådant scenario kan leda

Detektion av cellulära nivåer av c-di-GMP via biosensorer Bis-(3′,5′)-cyclisk di-guanosin-monofosfat (c-di-GMP) är en viktig molekyl som är involverad inom signalering för många olika biologiska processer hos bakterier, till exempel, reglering av cell cykeln och biofilm produktion. För att detektera cellulära nivåer av c-di-GMP, för att undersöka molekylens påverkan, har man skapat en biosensor,

The purpose of this study is to research how the principle of the best interest of the child expresses itself in custody disputes. The subject is based on how the principle does not have a clear description in the law. The district court therefore possesses room to interpret what they consider to be the best interest of the child in each individual case. The aim of the study is therefore to, throu

The rehabilitation techniques currently available for patients who suffer from injury to the ulnar or median nerve tends to give suboptimal results. Typically, adults who are operated due to a complete transection of the median or ulnar nerve never regain normal sensibility in the injured hand leading to severe limitations in terms of hand function. One of the biggest challenges in sensory rehabil

The commissioning phase is the last phase of a construction project when all subsystems come together to be tested as a whole, working as a single entity. This phase is often the most crucial and time-sensitive part of the project as the construction occupies space in the factory and inflicts down¬time in processes without adding value. Faults found in this phase can be time-consuming to correct a
