We show that recent robust adaptive beamformers, based on reconstructing either the noise-plus-interference or the data covariance matrices, are sensitive to the noise-plus- interference structure and degrade in the typical case when interferer steering vector mismatch exists, often performing much worse than common diagonally loaded sample covariance matrix based approaches, even when signal-of-i

Lifetime risk of developing breast cancer for Danish women is approx. 9%. Diagnostics are done by mammography, biopsy, and examination. Breast-conserving surgery followed by radiotherapy is standard for treatment of early-stage breast cancer. Studies report unsatisfying outcomes in up to one third of the patients. This review summarises the current surgical techniques. Oncoplastic breast surgery m

The formation of biomolecular condensates inside cells often involve intrinsically disordered proteins (IDPs), and several of these IDPs are also capable of forming dropletlike dense assemblies on their own, through liquid-liquid phase separation. When modeling thermodynamic phase changes, it is well known that finite-size scaling analysis can be a valuable tool. However, to our knowledge, this ap

Divorce increased dramatically during the twentieth century across the western world. There is surprisingly little research on the determinants of divorce during this transition. We investigate micro-level sociodemographic determinants of divorce in Sweden 1922–1967 using longitudinal data at individual and household level from southern Sweden, focusing on the associations between divorce and wome

Ground source heat pump systems, operating in conjunction with vertical ground heat exchangers, will play a key role in decarbonising heating and cooling of buildings. Design of traditional borehole heat exchangers relies on tools which implement routine analytical relationships between heat transferred and the temperature change in the ground and circulating thermal fluid. However, for novel pile

Kármán vortex streets are repeating patterns of swirling vortices, appearing when a fluid passes an obstacle at Re>50. We present an array of interacting vortices, a Kármán vortex city, that arises when a DNA solution flows through an array of micro posts at Re <0.5. Above thresholds in concentration and flow rate, the vortices formed behind posts interact, leading to concentration fluctuation wav

The evolution of surfaces exposed to an aggressive environment and mechanical load is studied. The evolution is the initial part of a stress corrosion process that leads to pitting, crack initiation and growing cracks. In conventional fracture analyses the growth rate of the crack may be computed using a modified Paris' law. However, a known or a postulated crack is required. A serious drawback is

När ett problem identifieras av statsmakten som bedöms beröra samhällslivet står inte sällan lösningen att finna inom straffrättens sfär. Metoden är enkel: det måste till fler och hårdare straff. Åtminstone är det enkelt att bilda sig den uppfattningen utifrån det offentliga samtalet och den bild som presenteras i våra nyhetsmedier. Samtidigt styrs straffrätten av principer som är ämnade att uppräWhen a socially relevant problem is identified by the state, the solution is often found in the sphere of criminal justice. The method is simple: more and harsher penalties are necessary. At the very least, it is easy to be led to believe so based on the public dialogue and the image presented by the media. At the same time, criminal law is governed by principles intended to uphold the restrictive

Grooming är ett vedertaget begrepp för det tillvägagångssätt som förövare använder sig av för att ta kontakt med barn, ofta på internet, för att slutligen begå sexuella brott mot barnet. Internetets expansion har på många sätt gett förövare fler tillvägagångssätt att komma i kontakt med barn. En stor andel av barnen i Sverige använder sociala medier, varav många någon gång har blivit kontaktade onGrooming is an established word for the approach that perpetrators are using to contact children, oftentimes over the Internet, ultimately to commit sexual offenses against the child. The expansion of the Internet has in many ways made it easier for perpetrators to approach and contact children. The vast majority of Swedish children use social media, many of whom at some point have been contacted

Den 17 december 2021 fick Sverige en ny visselblåsarlag. Lagen om skydd för personer som rapporterar om missförhållanden ersätter den tidigare lagstiftningen för visselblåsare. Lagen baseras på ett EU-direktiv från 2019 och den nya lagen kommer omfatta både fler verksamhetsutövare och fler personer som rapporterar om missförhållanden. Syftet med denna undersökning var att beskriva den nya lagen oc

Denna uppsats behandlar skydd för utländska investeringar och indirekt expropriation i internationell rätt. En erkänd regel inom internationell rätt föreskriver att egendom som tillhör utländska investerare inte får tillvaratas utan tillräcklig kompensation, oavsett om det är för ett offentligt ändamål eller inte. Medan en bedömning av direkt expropriation anses relativt okomplicerad att företa ha

Introduktion: Det första mötet mellan barn och föräldrar är betydelsefullt för barnets anknytning och föräldrarnas bindning. Genom att undersöka föräldrars upplevelse när separation sker under de första dygnen kan kunskap genereras utifrån ett föräldraperspektiv. Syfte: Syftet var tvådelat, att belysa föräldrars upplevelser av att separeras från sitt måttligt för tidigt födda barn i samband med fö

Klimatförändringarna blir mer synliga och fler internationella rapporter har beskrivit sannolika konsekvenser om världen inte agerar nu. Europeiska kommissionen gav nyligen ut en strategiplan för hur Europa kan bidra till Parisavtalet samt uppnå FN:s globala klimatmål. Kommissionens centrala vision är en klimatneutralekonomi där huvudmålet är att minska användningen av fossila bränslen. Vilken idé

Bart Streumer utilizes the principle “R: We do not have reasons to do what we cannot do” in order to justify that ‘ought’ implies ‘can’. This thesis questions Streumer’s assumption and instead argues that we have reasons to do what is psychologically-, physically and maybe even metaphysically impossible but not conceptually or logically impossible. As is shown in the thesis we do not have reasons

Financial incentives are increasingly being used to promote provision of environmental services (ES). Costa Rica was early with launching their Payments for Environmental Services (PES) scheme that rewards provision of ES and prevents further losses of the same. This study examines the links between Costa Rican PES scheme, pro-environmental behavior and forest conservation. PES-beneficiaries and f

The M&A activity among companies worldwide increases every year, at the same time as much as 70 % of all M&A’s are being reviewed as failures. M&A’s are a fast mean of positioning for a company, which makes the strategy increasingly relevant for high-tech companies since the high tech industry can change in both quick and disruptive ways. This study aims to explore the most common moti

The idea of orienting the design process towards the well-being of the patient is not something new in the world of architecture. That the form follows the function is usually but what must be taken into account is the dynamics of the process of understanding human needs. With each day that passes, complex changes of different kinds affect the human being and society as a whole in an unalterable t

Högsta domstolen har konstaterat att lojal samverkan är en förutsättning i ett längre avtalsförhållande. Vad som uttryckligen utelämnas i domskälen är vigilansprincipen som enligt doktrin utgör en tydlig motprincip till lojalitetsprincipen. Vigilansprincipen tar sikte på att en avtalspart ska tillvarata sina egna intressen. Med anledning av att vigilansprincipen inte har en framträdande roll inom The Swedish Supreme Court has stated that the principle of loyalty is a prerequisite to a long-term contractual relationship. Notably absent from the grounds of the judgements is the principle of vigilance, which is considered in doctrine to be an opposing principle to loyalty. In this thesis, the principle of vigilance means that a contracting party should protect its own interests. Since this pr

Japan continuously attempts to reinterpret war-renouncing Article 9 while at the same time stressing its devotion to pacifism, most recently through the Legislation for Peace and Security. The new Legislation allows Japan to engage in collective self-defense, which was considered unconstitutional for 70 years. This thesis examines Japan’s legitimization of such change, answering the question; how
