Cyclic Lorentzian Lie Groups

, 2015
We consider Lie groups equipped with a left-invariant cyclic Lorentzian metric. As in the Riemannian case, in terms of homogeneous structures, such metrics can be considered as different as possible from bi-invariant metrics. We show that several results

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

FEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

The Calabi metric for the space of Kähler metrics [PDF]

Mathematische Annalen, 2011
Given any closed Kaehler manifold we define, following an idea by Eugenio Calabi, a Riemannian metric on the space of Kaehler metrics regarded as an infinite dimensional manifold. We prove several geometrical features of the resulting space, some of which we think were already known to Calabi.

Optimal allocation of antenatal and young child nutrition interventions: an individual-based global burden of disease calibrated microsimulation

BMC Global and Public Health
Background Undernutrition remains a global crisis and is a focus of Sustainable Development Goals. While there are multiple known, effective interventions, complex interactions between prevention and treatment and resource constraints can lead to ...

Tackling equitable coverage and quality of care for neonates in hospitals: a pre-post assessment on asphyxia interventions in Mesoamerica

BMC Pediatrics, 2021
Background Intrapartum-related hypoxic events, or birth asphyxia, causes one-fourth of neonatal deaths globally and in Mesoamerica. Multidimensional care for asphyxia must be implemented to ensure timely and effective care of newborns.

Metrics for ranking ontologies [PDF]

, 2006
Representing knowledge using domain ontologies has shown to be a useful mechanism and format for managing and exchanging information. Due to the difficulty and cost of building ontologies, a number of ontology libraries and search engines are coming to ...

Single‐cell insights into the role of T cells in B‐cell malignancies

FEBS Letters, EarlyView.
Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Health in Yemen: losing ground in war time

Globalization and Health, 2018
Background The effect of the ongoing war in Yemen on maternal and child health (MCH) has not been comprehensively assessed. Providing a situational analysis at the governorate level is critical to assist in planning a response and allocating resources ...

Extremal K\"ahler metrics [PDF]

, 2014
This paper is a survey of some recent progress on the study of Calabi's extremal K\"ahler metrics. We first discuss the Yau-Tian-Donaldson conjecture relating the existence of extremal metrics to an algebro-geometric stability notion and we give some ...
