We show that in the absence of trilinear terms in the scalar potential of the Georgi-Machacek model, heavy charged scalars do not necessarily decouple from the h→γγ decay amplitude. In such scenarios, measurement of the Higgs to diphoton signal strength can place stringent constraints in the parameter space. Using the projected precisions at the High Luminosity LHC (HL-LHC) and the ILC, we find th

We compute the O(αsα2) and O(αs2α) contributions to the production cross section of a Z boson with one b jet at the Large Hadron Collider (LHC) and study their phenomenological relevance for LHC physics. The accurate prediction of hadronic Z+b-jet production is needed to control a background that greatly affects both the measurement of Higgs-boson properties and the searches of new physics at the

A search for pair production of the supersymmetric partners of the Higgs boson (higgsinos H) in gauge-mediated scenarios is reported. Each higgsino is assumed to decay to a Higgs boson and a gravitino. Two complementary analyses, targeting high- and low-mass signals, are performed to maximize sensitivity. The two analyses utilize LHC pp collision data at a center-of-mass energy s=13 TeV, the forme

Since the discovery of non-coding RNAs (ncRNAs) a new area has emerged in the field of biomarkers. NcRNAs are RNA molecules of different sizes that are transcribed as independent genes or as part of protein coding genes and are not translated, therefore they do not produce proteins. They have been classified accord-ing to their size and function and include micro RNAs (miRNAs), piwiRNAs (piRNAs),

En stödjande miljö är centralt för att kunna upprätthålla ett självständigt liv och effektivt aktivitetsutförande, särskilt med ökande ålder. För personer med funktionella begränsningar, som konsekvenserna av en ryggmärgsskada, är balansen mellan personens funktionella kapacitet och miljöns krav av yttersta vikt för att kunna leva ett så välfungerande liv som möjligt. Livslängden efter en ryggmärg

A reduced kinetic mechanism for methanol combustion at spark-ignition (SI) engine conditions is presented. The mechanism consists of 18 species and 55 irreversible reactions, small enough to be suitable for large eddy simulations (LES). The mechanism was reduced and optimized using the comprehensive mechanism (AramcoMech 2.0) as a starting point, to maintain performance at stoichiometric condition

We demonstrate that the wettability of cosmetic grade, silica-coated titanium dioxide nanoparticles may be tuned by simply soaking them in a cyclic silicone oil. This allows for tuning the type of emulsion that they stabilize, from oil-in-water to water-in-oil. By analyzing the sedimentation of water-in-oil emulsions, the effect of the soaking time (wettability) on drop size and drop-drop interact

Influence of sintering temperature on both phase composition and structure of ceramic matrix composites based on cubic boron nitride with binders in a form of Al and the Ti, Cr, V carbides are investigated by methods of physical materials science. As the object of study, three cBN–TiC–Al, cBN–Cr3C2–Al, cBN–VC–Al compositions containing 60% vol. cBN are selected. The composites are obtained by high

Importance: In Alzheimer disease (AD), tau filaments form neuronal inclusions in neurites (neuropil threads) and in somata (neurofibrillary tangles), and neurite tau pathology constitutes the most common pathology. Positron emission tomography (PET) ligands have been developed to detect in vivo tau pathology in AD. However, the association of AD tau pathology post mortem with in vivo tau PET reten

Cancer stem cell populations are important for the initiation, progression and metastasis of tumors. The mechanisms governing cancer stem cell control are only partially understood, but activation of the Notch3 pathway plays a crucial role in the maintenance of breast cancer stem cells. Expression of Cartilage Oligomeric Matrix Protein (COMP) in breast cancer cells is correlated with poor survival

Background: Evaluation of male fertility includes standard semen analysis; however, there is uncertainty about the value of sperm parameters in predicting fertility. Objective: To evaluate the association between semen parameters and fatherhood during a long-time period. Materials and methods: Semen parameters (total sperm count, concentration, motility, and morphology) and sperm DNA fragmentation

Donor-acceptor (D-A) copolymers typically show two absorption peaks in the visible region, flanking a valley region of limited absorptivity. One strategy for more panchromatic light harvesting is to incorporate side-groups orthogonal to the polymer backbone, which enable 2D π conjugation and can give rise to additional absorption peaks. Here we design and synthesize two D-A polymers which both car
