Toward a complete description of b → uℓ − ν ¯ $$ \overline{\nu} $$ within the Weak Effective Theory decays

Journal of High Energy Physics, 2023
We fit the available data on exclusive semileptonic b → uℓ − ν ¯ $$ \overline{\nu} $$ decays within the Standard Model and in the Weak Effective Theory. Assuming Standard Model dynamics, we find V ub = 3.59 − 0.12 + 0.13 × 10 − 3 $$ \left|{V}_{ub}\right|=

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Simultaneous determination of CKM angle $\gamma$ and charm mixing parameters

, 2021
A combination of measurements sensitive to the $CP$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa (CKM) unitarity triangle and to the charm mixing parameters that describe oscillations between $D^0$ and $\overline{D}^0$ mesons is performed.

Constraining the CKM parameters usingCPviolation in semileptonicBdecays [PDF]

Physical Review D, 1999
We discuss the usefulness of the CP violating semi-leptonic asymmetry a_{SL} not only as a signal of new physics, but also as a tool in constraining the CKM parameters. We show that this technique could yield useful results in the first years of running at the B factories.

Constraining |V cs | and physics beyond the Standard Model from exclusive (semi)leptonic charm decays

Journal of High Energy Physics
We study the available data on exclusive leptonic and semileptonic c → sℓ + ν decays within the Standard Model and beyond. Our analysis accounts for theory correlations between the relevant hadronic matrix elements through application of dispersive ...

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

PHYSIOLOGICAL RESPONSES OF COWPEA PLANTS TO IAA AND ORGANIC MANURES IN SANDY SOIL [PDF]

Journal of Plant Production, 2005
Two field experiments were conducted during two successive seasons in the Nubaria region in Egypt. The soil was supplemented with organic manuras, either chicken (CKM) or farmyard (FYM). Foiiar application of the cowpea plants with indole acetic acid (lAA)
