Channel Access Probability in Unslotted IEEE 802.15.4 csma Under Correlated Clear Channel Assessments

open access: yesIEEE Access
Correlation between successive clear channel assessments in unslotted carrier sense multiple access with collision avoidance (CSMA/CA) is commonly assumed in the literature to be negligible for modeling the medium access control algorithm.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Dirac Cat States in Relativistic Landau Levels

open access: yes, 2007
We show that a relativistic version of Schrodinger cat states, here called Dirac cat states, can be built in relativistic Landau levels when an external magnetic field couples to a relativistic spin 1/2 charged particle. Under suitable initial conditions,

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Wigner functions, squeezing properties and slow decoherence of atomic Schrodinger cats

open access: yes, 1999
We consider a class of states in an ensemble of two-level atoms: a superposition of two distinct atomic coherent states, which can be regarded as atomic analogues of the states usually called Schrodinger cat states in quantum optics.

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

open access: yesMolecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Migration and Economic Growth: a 21st Century Perspective [PDF]

open access: yes
While there is extensive literature on the determinants of migration and its microeconomic effects, the New Zealand theoretical or empirical literature specifically examining the effects of migration on economic growth is not as comprehensive.

Amabile‘s consensual assessment technique: Why has it not been used more in design creativity research? [PDF]

open access: yes, 2012
Amabile’s Consensual Assessment Technique (CAT) has been described as the “gold standard” of creativity assessment; been extensively used within creativity research, and is seen as the most popular method of assessing creative outputs.

Metric minimizing surfaces revisited

open access: yes, 2018
A surface which does not admit a length nonincreasing deformation is called metric minimizing. We show that metric minimizing surfaces in CAT(0) spaces are locally CAT(0) with respect to their intrinsic ...
