Evaluating service performance of public bus transit service: a case study of Addis Ababa, Ethiopia

Urban, Planning and Transport Research, 2022
To determine the operators’ strengths and shortcomings in the delivery of transit service, it is crucial to evaluate bus transit service performance from the viewpoint of the consumer.

Delocalization-Localization Transition due to Anharmonicity [PDF]

Physical Review Letters, 2008
Analytical and numerical calculations for a reduced Fermi-Pasta-Ulam chain demonstrate that energy localization does not require more than one conserved quantity. Clear evidence for the existence of a sharp delocalization-localization transition at a critical amplitude is given.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Spatial patterns of access-density mismatch reveal infrastructure gaps and strategic opportunities for new housing

npj Sustainable Mobility and Transport
The divergence from idealized economic models can lead to a mismatch between regional access and local density. Here, theoretical explanations and empirical investigations of “access-density mismatch” are conducted to explain alignment, or misalignment ...

Understanding Transit Ridership Demand for a Multi-Destination, Multimodal Transit Network in an American Metropolitan Area, Research Report 11-06 [PDF]

, 2012
This study examines the factors underlying transit demand in the multi-destination, integrated bus and rail transit network for Atlanta, Georgia. Atlanta provides an opportunity to explore the consequences of a multi-destination transit network for bus ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Strategic planning for a sustainable local-regional transit-oriented development

Urban, Planning and Transport Research
Regional enlargement and Transit-Oriented Development (TOD) has in Sweden been an active policy and strategy at both municipal, regional, and national level to make society more resource efficient and strengthen local labour markets.

Superconductor-insulator transition and energy localization [PDF]

Physical Review B, 2010
We develop an analytical theory for generic disorder-driven quantum phase transitions. We apply this formalism to the superconductor-insulator transition and we briefly discuss the applications to the order-disorder transition in quantum magnets. The effective spin-1/2 models for these transitions are solved in the cavity approximation which becomes ...
