Scattering amplitudes are often split up into their color (su(N) ) and kinematic components. Since the su(N) gauge part can be described using flows of color, one may anticipate that the su(2 ) ⊕ su(2 ) kinematic part can be described in terms of flows of chirality. In two recent papers we showed that this is indeed the case, introducing the chirality-flow formalism for standard model calculations
In a large social science literature, unequal rural class structures (“landlordism”) are as-sociated with authoritarian political outcomes. This paper revisits the debate focusingon the electoral consequences of land inequality in Prussia, the locus classicus of the per-nicious effects of landlordism, and Sweden, often perceived as Prussia’s opposite, with afarmer-dominated social structure and st
Lignins are aromatic polymers found in fibrous plants, and a major side-product of paper pulping. They are under exploited due to a combination of economic and technical challenges. Valorisation efforts aim to resolve this, but these rely on informative and reliable analytical feedback. The diverse and complex structures of compounds found in lignins makes analysis difficult. This thesis outlines
Klimatavtryck från Sveriges och världens rikaste har ökat stadigt sedan 90-talet. Samtidigt har de med lägst inkomst minskat sina utsläpp. Nu undersöker forskare om begränsningar för superrika kan bidra till minskade utsläpp. Utopi eller frihetskränkande?
Defining minimal standards for data collection is key to creating interoperative, searchable genomic and clinical databases. We highlight here the 1+Million Genomes Minimal Dataset for Cancer, encompassing 140 items in 8 domains to foster the collection of cancer data, inform transnational cooperation and advance precision cancer medicine.
DIRAC is a freely distributed general-purpose program system for one-, two-, and four-component relativistic molecular calculations at the level of Hartree-Fock, Kohn-Sham (including range-separated theory), multiconfigurational self-consistent-field, multireference configuration interaction, electron propagator, and various flavors of coupled cluster theory. At the self-consistent-field level, a
Resources have always been at the heart of civil society theorizing. While many earlier theories have focused on resources in the forms of money, people, ideas, or personnel, recent debates highlight the Internet and social media as new environments for resource mobilization. This chapter contributes to current research by comparing the human, economic, and political resources accumulated both off
Reflections on ongoing work on the interactions of welfare, planning and landscape, based on a session at the 2021 ECLAS conference.
The armed conflict shaped and determined land-uses, water access and social and environmental norms in highlands regions in Colombia for several decades. The withdrawal of the Revolutionary Armed Forces of Colombia (FARC) after the Peace Agreement with the government of Colombia in 2016, has brought new dynamics in access and uses of land leading to increasingly visible social-environmental impact
We introduce a family of boundary confinements for Coulomb gas ensembles, and study them in the two-dimensional determinantal case of random normal matrices. The family interpolates between the free boundary and hard edge cases, which have been well studied in various random matrix theories. The confinement can also be relaxed beyond the free boundary to produce ensembles with fuzzier boundaries,
Musculoskeletal health is critical for human function, enabling mobility, dexterity and the ability to work and actively participate in all aspects of life. It is essential for maintaining economic, social and functional independence as well as human capital across the life course. Action is needed and the Global Alliance for Musculoskeletal Health (G-MUSC) is working with the entire musculoskelet
Most university biobanks begin like other university research projects, i.e. with an idea conceived by an individual researcher in pursuit of his/her own research interests, publications, funding and career. Some biobanks, however, come to have scientific value that goes beyond the projects that were initially responsible for the collection of the samples and data they contain. Such value may deri
We consider the reliability function of Markov channels with feedback and variable length channel codes. We extend Burnashev's [3] classic result to this case and present a single letter characterization for the reliability function.
We review recent progress and motivate the need for further developments in nuclear optical potentials that are widely used in the theoretical analysis of nucleon elastic scattering and reaction cross sections. In regions of the nuclear chart away from stability, which represent a frontier in nuclear science over the coming decade and which will be probed at new rare-isotope beam facilities worldw
Bicelles are disk-shaped models of cellular membranes used to study lipid–protein interactions, as well as for structural and functional studies on transmembrane proteins. One challenge for the incorporation of transmembrane proteins in bicelles is the limited range of detergent and lipid combinations available for the successful reconstitution of proteins in model membranes. This is important, as
The Amit conjecture about word maps on finite nilpotent groups has been shown to hold for certain classes of groups. The generalised Amit conjecture says that the probability of an element occurring in the image of a word map on a finite nilpotent group G is either 0, or at least 1/|G|. Noting the work of Ashurst, we name the generalised Amit conjecture the Amit–Ashurst conjecture and show that th
