1. Dementia is a clinical syndrome with several causes whichcreates impairments in mental ability, personality, affect andsocialisation.2. Information from family members can be very useful in theearly identification of cognitive impairment.3. Patients presenting with cognitive impairment should be evaluatedfor potentially reversible causes, with a range of laboratorytests and investigations.4. Sh
Apart from microhardness and elastic modulus, the stress-strain relation is another important characteristic that more and more scholars have been trying to extract from nanoindentation. With the development of artificial intelligence and computer technology, a machine learning based method is proposed in this paper to extract stress-strain curve of grey cast iron using sharp nanoindentation. Firs
Building extraction has attracted considerable attention in the field of remote sensing image analysis. Fully convolutional network modelling is a recently developed technique that is capable of significantly enhancing building extraction accuracy. It is a prominent branch of deep learning and uses advanced state-of-the-art techniques, especially with regard to building segmentation. In this paper
Abstrakt. Gradientval av överföringar gör det möjligt att förenkla polarisationsöverföringssekvenser genom att utelämna kemiska skift-återfokuseringspulser. Funktionerna hos en förenklad STEM-sekvens med tre pulser för {1H-13C} polarisationsöverföring har studerats vid 2 Tesla på ett helkropps MR-system med avseende på användning av MR-spektroskopi in vivo. Den observerade signalen ökas genom nett
Mechanisms of motor deficits (e.g. hemiparesis and hemiplegia) secondary to stroke and traumatic brain injury remain poorly understood. In early animal studies, a unilateral lesion to the cerebellum produced postural asymmetry with ipsilateral hindlimb flexion that was retained after complete spinal cord transection. Here we demonstrate that hindlimb postural asymmetry in rats is induced by a unil
A native passive film on 25Cr-7Ni super duplex stainless steel was analyzed using synchrotron hard X-ray photoemission electron microscopy, focusing on variations between individual grains of ferrite and austenite phases. The film consists of an oxide inner layer and an oxyhydroxide outer layer, in total 2.3 nm thick. The Cr content is higher in the outer than the inner layer, ca. 80 % on average.
This study examines how Islamic beliefs affect host-guest interactions from the perspectives of local people in two Islamic heritage villages in Iran. Face-to-face interviews with 51 people across the two settings highlight the significant influence of Islamic beliefs on host-guest interactions and indicate that these beliefs can be supportive of tourism. However, religiosity also significantly in
We investigate the production of primordial Gravitational Waves (GWs) arising from First Order Phase Transitions (FOPTs) associated to neutrino mass generation in the context of type-I and inverse seesaw schemes. We examine both “high-scale” as well as “low-scale” variants, with either explicit or spontaneously broken lepton number symmetry U(1)L in the neutrino sector. In the latter case, a pseud
The striking similarities that have been observed between high-multiplicity proton-proton (pp) collisions and heavy-ion collisions can be explored through multiplicity-differential measurements of identified hadrons in pp collisions. With these measurements, it is possible to study mechanisms such as collective flow that determine the shapes of hadron transverse momentum (pT) spectra, to search fo
The effect of electroporation parameters on the reversible permeabilization of cells in Thai basil leaves and, specifically, cells on the leaf surface was investigated, as electroporation of stomatal guard cells decreases drying times. Various combinations of PEF and MEF parameters were applied. The effect of these parameters on the electroporation of the leaf surface was assessed with microscopic
Many animal species use tools, but human technical engagement is more complex. We argue that there is coevolution between technical engagement (the manufacturing and use of tools) and advanced forms of causal cognition in the human (Homo) lineage. As an analytic tool, we present a classification of different forms of causal thinking. Human causal thinking has become detached from space and time, s
In this article, Roybon and colleagues developed a protocol to efficiently and rapidly generate hippocampus neurons from human induced pluripotent stem cells, which they used to model Alzheimer disease and develop a gene therapy approach to modulate the expression of genes involved in synaptic transmission.
BACKGROUND: Iodine has been suggested to protect against breast cancer, but there are no epidemiologic studies on individual risk. An interesting finding is that in areas where the exposure to both selenium and iodine are high (e.g., Japan), the risk of breast cancer is lower than in areas where selenium is high and iodine low (e.g., United States), or in areas where both are low (e.g., Northern E
Lunds kommuns klimatpolitiska råd bildades hösten 2018 med uppdrag att utvärdera hur Lunds kommuns samlade politik är förenlig med de klimatmål somantagits av kommunfullmäktige. Rådet, som består av forskare från Lunds universitet (LU) och SLU Alnarp, har sammantaget en bred tvär- och mångvetenskaplig kompetens och en gedigen erfarenhet av samverkan med samhället. Samarbetet mellan Lunds kommun oc
OBJECTIVE: The authors examined the association between alcohol use disorder (AUD) and risk of suicide, before and after accounting for psychiatric comorbidity, and assessed the extent to which the observed association is due to a potentially causal mechanism or genetic and familial environmental confounding factors that increase risk for both. METHODS: Longitudinal population-wide Swedish medical
Differences in pancreatic islet susceptibility during type 1 diabetes development may be explained by interislet variations. This study aimed to investigate if heterogeneities in vascular support and metabolic activity in rat and human islets may explain why some islets are attacked earlier than other islets. In rats, highly blood perfused islets were identified by injection of microspheres into t
A major challenge to plant growth and survival are changes in temperature and diminishing water supply. During acute temperature and water stress, plants often express stress proteins, such as dehydrins, which are intrinsically disordered hydrophilic proteins. In this article, we investigated how the dehydrin Lti30 from Arabidopsis thaliana stabilizes membrane systems that are exposed to large cha
BACKGROUND: The four-kallikrein (4K) panel has been demonstrated to improve prediction of aggressive prostate cancer compared with prostate-specific antigen (PSA) among men with moderately elevated PSA levels. However, the development and testing of the 4K panel has been conducted primarily in White men, with limited data in African Americans and no studies in other racial and ethnic groups. METHO
BACKGROUND: Surgery for total colonic aganglionosis (TCA) is designed to preserve continence and achieve satisfactory quality of life. This study evaluated a comprehensive group of clinical and social outcomes.METHODS: An international multicentre study from eight Nordic hospitals involving examination of case records and a patient-reported questionnaire survey of all patients born with TCA betwee
