Season's greetings! Season's greetings! Published 19 December 2024 The holidays are just around the corner! Soon, we will hit the couch for some well-deserved rest and lots of goodies. But first: Thanks to all our users during the year whose projects and exciting research make the Lab a fun place to be. Thanks to Lunds universitet for making us a Corefacility as of next year! We wish everyone jo

Microsoft Word - 2112 curatorial press.docx Landlines / Linhas Fixas Landline is a compound word that forms a drawing in one’s mind. It is a horizontal contour that cuts through space, defining the ground and the above. Drawing a line is simple enough, but to spatially define a void is an abstract thought. One needs to reinvent physics symbolically. A crudely drawn connection between two points is

Cytosolic NADPH can be directly oxidized by a calcium-dependent NADPH dehydrogenase, NDB1, present in the plant mitochondrial electron transport chain. However, little is known regarding the impact of modified cytosolic NADPH reduction levels on growth and metabolism. Nicotiana sylvestris plants overexpressing potato NDB1 displayed early bolting whereas sense-suppression of the same gene led to de
Background: Human breast tissue undergoes phases of proliferation, differentiation and regression regulated by changes of the levels of circulating sex hormones during the menstrual cycle or aging. Ovarian hormones also likely play a key role in the etiology and biology of breast cancer. Reports concerning the proliferative effects of steroid hormones on the normal epithelium of human breast have
This work presents a digital calibration technique in continuous-time (CT) ΔΣ analog to digital (A/D) converters. The converter is clocked at 144MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching (DEM) is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measured
Chronic hyperglycemia leads to pancreatic beta-cell dysfunction characterized by diminished glucose-stimulated insulin secretion (GSIS), but the precise cellular processes involved are largely unknown. Here we show that pancreatic beta-cells chronically exposed to a high glucose level displayed substantially increased amounts of stress fibers compared with beta-cells cultured at a low glucose leve
With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. Therefore, designing large Systems on Chip makes it necessary to search for new implementation methods. In this
Background: Neutralizing antibodies provide markers for vaccine-induced protective immunity in many viral infections. By analogy, HIV-1 neutralizing antibodies induced by immunization may well predict vaccine effectiveness. Assessment of neutralizing antibodies is therefore of primary importance, but is hampered by the fact that we do not know which assay(s) can provide measures of protective immu
Although no common genetic defect has been described in chronic lymphocytic leukemia (CLL), recurrent genomic aberrations (i.e. deletions of chromosome 11q, 13q, 17p and trisomy 12) are important for prognostication. Deletion of 13q as single aberration is associated with the best prognosis, whereas del(11q) and del(17p) predict a poor outcome. Recent development of high-resolution genomic techniq
OBJECTIVE: The first-appearing β-cell autoantibody has been shown to influence risk of type 1 diabetes (T1D). Here, we assessed the risk of autoantibody spreading to the second-appearing autoantibody and further progression to clinical disease in the Environmental Determinants of Diabetes in the Young study.RESEARCH DESIGN AND METHODS: Eligible children with increased HLA-DR-DQ genetic risk for T1
This paper presents a robust timing synchronization method for full duplex orthogonal frequency division multiplexing (OFDM) systems based on Long Term Evolution (LTE). The proposed method contains two essential steps: 1) time alignment between the desired signal and self-interference 2) normalized synchronization peak (NSP) index switching. The time alignment is to make the difference in arrival
The overall system performance of massive MIMO is improved by equipping user terminals with multiple antennas. In this paper, we investigate transceiver designs for the case of a single downlink stream and in particular, we study the uplink pilot design. Moreover, we study the consequences of channel estimation errors at the base-station, and to what extent a dual-antenna terminal can get access t
We demonstrate one-dimensional (1D) electrical modeling of InP nanowire array solar cells. This 1D modeling gives accurate description of the current voltage response even at high surface recombination velocity. The 1D electrical model decreases the simulation time by 3 orders of magnitude compared to a full three-dimensional (3D) model.
Världen är föränderlig. För att kunna överleva måste allt liv kunna anpassa sig till rådande förhållanden. För cellen, livets minsta enhet, sker detta bland annat genom reglering av produktionstakten av proteiner, vilka är de molekyler som utför de flesta grundläggande funktioner. En speciell klass av proteiner utgörs av så kallade transkriptionsfaktorer. Dessa slår av eller på en gens produktion Living organisms can be viewed as complex biological machines. In order to function, they must regulate their internal mechanism to do the right thing, at the right time, and in the right amount. Part of this regulation is encoded in gene regulatory networks. These are built up of genes which produce special proteins (transcription factors, tf) that regulate other tf-producing genes. Thus a networ
Decidualization is a process in which endometrial stromal fibroblasts differentiate into specialized secretory decidual cells and essential for the successful establishment of pregnancy. The underlying mechanism during decidualization still remains poorly defined. Because decidualization and fibroblast activation share similar characteristics, this study was to examine whether fibroblast activatio
There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. This work used experimental measurements and numerical simulations to gain a deeper knowledge about the measurement, prediction and evaluation of vibrations in
During evolution the human brain has increased drastically in size compared to that of other primates. However, little is known about primate brain development as it is difficult to study human and primate brains in the laboratory due to the scarcity of tissues. Yet, it is essential to study primate brains and understand the molecular features leading to the human brain’s unique cognitive function
Having close-to-capacity performance and low error floor, even for small block lengths, make spatially coupled serially concatenated codes (SC-SCCs) a very promising class of codes. However, classical window decoding of SC-SCCs either limits the minimum block length or requires a large number of iterations, which increases the complexity and constrains the degree to which an SC-SCC decoder archite
en_WS07-2_singleSlit 1 Actually, light waves do go around the corners of a house. But there is a significant difference in scale: light waves are one million 9mes smaller than sound waves. That's why the effect is so small that you cannot see the light bending around the house (which is much larger). On the other hand, you can
