Physics with boosted top quarks

open access: yes, 2014
The production at the LHC of boosted top quarks (top quarks with a transverse momentum that greatly exceeds their rest mass) is a promising process to search for phenomena beyond the Standard Model.

Top quark physics at CDF.

open access: yes, 2012
We present recent measurements from CDF of spin correlations, of the top decay relative branching ratio BR(t$\rightarrow$Wb)/$\Sigma_{\rm q}$BR(t$\rightarrow$Wq) and the derived indirect constraint on the $\vert$V$_{\rm tb}$$\vert$ CKM matrix element, of the single top production cross section and the derived direct constraint on $\vert$V$_{\rm tb}

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Re‐Awakening Public Attention to the Silent Pandemic of Cancer Among Older Adults in Low‐ and Middle‐Income Countries

open access: yesAging and Cancer, EarlyView.
ABSTRACT As global populations age, cancer is increasingly becoming a leading cause of morbidity and mortality among older adults, particularly in low‐ and middle‐income countries (LMICs). Despite accounting for the majority of new cancer cases and deaths, older individuals remain underrepresented in cancer research, clinical guidelines, and health ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Search for central exclusive production of top quark pairs in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with tagged protons

open access: yesJournal of High Energy Physics
A search for the central exclusive production of top quark-antiquark pairs ( t t ¯ $$ \textrm{t}\overline{\textrm{t}} $$ ) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13 ...

CKM physics with top [PDF]

open access: yesProceedings of 9th International Workshop on the CKM Unitarity Triangle — PoS(CKM2016), 2017
We summarize direct measurements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element, $\bf{V_{tb}}$, using single top quark events at the ATLAS and CMS experiments and an indirect measurement of $\bf{V_{tb}}$ using top quark pair events at CMS experiment of CERN LHC based on the data collected at different center-of-mass energies of 7, 8 and 13 TeV.

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.
