Constructing social division to support cooperation : theory and evidence from Nepal [PDF]

open access: yes, 2013
Many societies are divided into multiple smaller groups. The defining feature of these groups is that certain kinds of interaction are more likely to take place within a group than across groups.

Immunization and Aging: a Learning Process in the Immune Network

open access: yes, 1998
The immune system can be thought as a complex network of different interacting elements. A cellular automaton, defined in shape-space, was recently shown to exhibit self-regulation and complex behavior and is, therefore, a good candidate to model the ...

High Scale Boundary Conditions in Models with Two Higgs Doublets [PDF]

open access: yes, 2019
We investigate high scale boundary conditions on the quartic Higgs-couplings and their $\beta$-functions in the Type-II Two Higgs Doublet Model and the Inert Doublet Model.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

HAVA TRAFİK KONTROLU BENZETİMİNDE ETKİLEŞİMLİ ÇOKLU MODEL (INTERACTING MULTIPLE MODEL-IMM) KESTİRİM PERFORMANSI VE KALMAN FİLTRESİ İLE KARŞILAŞTIRILMASI

open access: yesHavacılık ve Uzay Teknolojileri Dergisi, 2008
It is known that adaptive estimation models are used in different time intervals of the motion projection of maneuvering targets. In this study Interacting Multiple Model (IMM) estimation technique is implemented and its performance is tested on an air

Generalization of Boltzmann Equilibration Dynamics

open access: yes, 2002
We propose a novel approach in the study of transport phenomena in dense systems or systems with long range interactions where multiple particle interactions must be taken into consideration.

Multiple Tidal Disruptions as an Indicator of Binary Super-Massive Black Hole Systems [PDF]

open access: yes, 2010
We find that the majority of systems hosting multiple tidal disruptions are likely to contain hard binary SMBH systems, and also show that the rates of these repeated events are high enough to be detected by LSST over its lifetime.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Adaptive Multi-Model Fault Diagnosis of Dynamic Systems for Motion Tracking

open access: yesIEEE Access
For most real-world systems, the exact description of possible faults is unknown, making these faults difficult to detect, and even more difficult to identify. The most promising way is to use multiple hypotheses for faults to find the best fitting fault
