Simulator of radiation biological effects in tumor in order to determinate the tumor control probability

open access: yesInformatics in Medicine Unlocked, 2019
Background: Currently, tumor control probability (TCP) can be determined through experiments and observations, which enable deriving its values and construction of phenomenological and mechanistic TCP models.

Linear birth and death processes under the influence of disasters with time-dependent killing probabilities

open access: yesStochastic Processes and their Applications, 1993
Supercritical linear birth-and-death processes are considered under the influence of disasters that arrive as a renewal process independent of the population size. The killing probability in a disaster is a function of time from the last disaster. A necessary and sufficient condition for almost sure extinction is derived.

Construction of a Multitissue Cell Atlas Reveals Cell‐Type‐Specific Regulation of Molecular and Complex Phenotypes in Pigs

open access: yesAdvanced Science, EarlyView.
This research conducts an in‐depth investigation of cell‐type‐specific regulatory mechanisms underlying molecular and complex phenotypes through integrative analysis of multitissue single‐nucleus RNA sequencing, bulk RNA‐seq, and genome‐wide association study (GWAS) data in pigs.

The Determinants of Punishment: Deterrence, Incapacitation and Vengeance [PDF]

open access: yes
Does the economic model of optimal punishment explain the variation in the sentencing of murderers? As the model predicts, we find that murderers with a high expected probability of recidivism receive longer sentences.

Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

open access: yesAdvanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Influence of maneuverability on helicopter combat effectiveness [PDF]

open access: yes
A computational procedure employing a stochastic learning method in conjunction with dynamic simulation of helicopter flight and weapon system operation was used to derive helicopter maneuvering strategies. The derived strategies maximize either survival

Single‐Cell Dissection Reveals Immune Dysregulation After CD5 or CD7‐Directed Chimeric Antigen Receptor T‐Cell Therapy

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA/TCR/BCR sequencing reveals that 5CAR therapy in T‐ALL induces T‐cell exhaustion, reduces EBV‐associated TCRs, lowers TCR/BCR diversity, and increases NK/DC/monocyte activation and function. In contrast, 7CAR therapy reduces multiple pathogen‐associated TCRs, enhances NK cell activation and function, decreases monocyte activation, and ...

在以农业为主的景观中哺乳动物对易地放归的野生火鸡捕食的空间分布预测

open access: yesWildlife Letters
Translocating prey into unfamiliar environments may alter predator‐prey interactions on space utilization, making prey more vulnerable to predation. We predicted that the greater the edge density of cropland and developed land, the higher the probability

DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss

open access: yesAdvanced Science, EarlyView.
Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...

Technical Note—Probability of Kill and Expected Destroyed Value if the Underlying Distributions Are Rotationally Symmetric [PDF]

open access: yesOperations Research, 1976
We derive formulas for the probability of killing a point target and for the expected destroyed value of an area target when the value density function of the area target, the damage function, and the distribution of the center of damage function around the target center are rotationally symmetric. The result generalizes several well-known formulas.
