Tunable, division-independent control of gene activation timing by a polycomb switch

open access: yesCell Reports, 2021
Summary: During development, progenitors often differentiate many cell generations after receiving signals. These delays must be robust yet tunable for precise population size control.

Distributed downlink multi-cell processing requiring reduced-rate back-haul data exchange [PDF]

open access: yes, 2011
Different-complexity Multi-Cell Processing (MCP) schemes employing Distributed Signal-to-Interference-Leakage-plus-Noise-Ratio (SILNR) precoding techniques are proposed, which require reduced back-haul data exchange in comparison to the conventional MCP ...

Delay-Driven Computation Task Scheduling in Multi-Cell Cellular Edge Computing Systems

open access: yesIEEE Access, 2019
This paper studies the joint scheduling of subcarrier, base station, transmit power, and virtual machine in multi-cell cellular edge computing systems to minimize the total delay experienced by tasks of users.

Effect of Delay on Selection Dynamics in Long-Term Sphere Culture of Cancer Stem Cells

open access: yesDiscrete Dynamics in Nature and Society, 2013
To quantitatively study the effect of delay on selection dynamics in long-term sphere culture of cancer stem cells (CSCs), a selection dynamic model with time delay is proposed.

Phytotoxicity of Sicyos deppei during tomato germination and its effects on the role of ABA and cell wall enzymes

open access: yesBotan‪ical Sciences, 2015
Sicyos deppei is a harmful weed that grows in central Mexico, decreasing crop productivity by allelochemical release via lixiviation of the aerial organs through raining. S.

Performance analysis and optimal cooperative cluster size for randomly distributed small cells under cloud RAN [PDF]

open access: yes, 2016
One major advantage of cloud/centralized radio access network is the ease of implementation of multi-cell coordination mechanisms to improve the system spectrum efficiency (SE).

Reevaluation of the role of parallel fiber synapses in delay eyeblink conditioning in mice using Cbln1 as a tool

open access: yesFrontiers in Neural Circuits, 2013
The delay eyeblink conditioning (EBC) is a cerebellum-dependent type of associative motor learning. However, the exact roles played by the various cerebellar synapses, as well as the underlying molecular mechanisms, remain to be determined.

Epithelial cell-turnover ensures robust coordination of tissue growth in Drosophila ribosomal protein mutants.

open access: yesPLoS Genetics, 2021
Highly reproducible tissue development is achieved by robust, time-dependent coordination of cell proliferation and cell death. To study the mechanisms underlying robust tissue growth, we analyzed the developmental process of wing imaginal discs in ...

Dual Targeting of Multiple Myeloma Stem Cells and Myeloid-Derived Suppressor Cells for Treatment of Chemotherapy-Resistant Multiple Myeloma

open access: yesFrontiers in Oncology, 2021
Here we review the insights and lessons learned from early clinical trials of T-cell engaging bispecific antibodies (BsABs) as a new class of biotherapeutic drug candidates with clinical impact potential for the treatment of multiple myeloma (MM).

Effects of cell cycle noise on excitable gene circuits [PDF]

open access: yes, 2016
We assess the impact of cell cycle noise on gene circuit dynamics. For bistable genetic switches and excitable circuits, we find that transitions between metastable states most likely occur just after cell division and that this concentration effect ...
