A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

open access: yesAging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

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 ...

Chance Constrained Efficiency Evaluation

Management Science, 1995
A model for efficiency evaluation based upon the theory of chance constrained programming is developed. The model uses a piecewise linear envelopment of confidence regions for observed stochastic multiple-input multiple-output combinations in the Data Envelopment Analysis (DEA) tradition.

Efficient Extended ABAC Evaluation

Proceedings of the 23nd ACM on Symposium on Access Control Models and Technologies, 2018
A main challenge of attribute-based access control (ABAC) is the handling of missing information. Several studies show that the way standard ABAC mechanisms (e.g., XACML) handle missing information is flawed, making ABAC policies vulnerable to attribute-hiding attacks.

The Human Efficiency Evaluator

2017
With more and more systems and machines operating autonomously, the role of the operator is changing from “being actively in control” to “monitor and intervene”. Human Machine Interfaces (HMI) therefore need to be optimized so that they can efficiently be monitored by a human.

Evaluating Energy Efficiency

2015
Nature of resource planning has changed dramatically since 1970s due to increased diversity in resource options such as renewable alternatives, demand-side management, space conditioning, cogeneration of heat and electricity in industrial applications, and deregulation of the energy market.

An Efficient Infertility Evaluation

Clinical Obstetrics & Gynecology, 2011
The biological clock is a major adversary to human reproduction. Not only does fecundity wane with time, but so does an infertility patient's emotional reserve. Therefore, a well-organized approach to evaluating, treating, and referring patients to subspecialty centers when necessary is critical to optimally manage infertility.

Efficient XPath Evaluation

2005
Inspired by the best querying performance of ViST among the rest of the approaches in the literature, and meanwhile to overcome its shortcomings, in this paper, we present another efficient and novel geometric sequence mechanism, which transforms XML documents and XPath queries into the corresponding geometric data/query sequences. XML querying is thus
