Sensors for Ultrasonic Nondestructive Testing (NDT) in Harsh Environments

open access: yesSensors, 2020
In this special issue of Sensors, seven peer-reviewed manuscripts appear on the topic of ultrasonic transducer design and operation in harsh environments: elevated temperature, high gamma and neutron fields, or the presence of chemically aggressive ...

MAXIMIZATION OF PRODUCTION AND NET INCOME IN AGRO-FOREST SYSTEMS

open access: yesEngenharia Agrícola, 2022
In this study, we present computational procedures to solve problems for the maximization of production and net income from crops or trees in a randomly generated agroforestry system with limited inputs, based on the Logarithmic Barrier Method.

Motion-induced radiation from electrons moving in Maxwell's fish-eye [PDF]

open access: yes, 2013
In \u{C}erenkov radiation and transition radiation, evanescent wave from motion of charged particles transfers into radiation coherently. However, such dissipative motion-induced radiations require particles to move faster than light in medium or to encounter velocity transition to pump energy.

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

open access: yesMolecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...

Adverse prognosis gene expression patterns in metastatic castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
We aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression‐based pathways with clinical outcomes. Loss of AR signaling, high proliferation, and a glycolytic phenotype were independently prognostic for poor outcomes, and an adverse transcriptional feature score incorporating these pathways ...

Preparation of activated carbon from sawdust using microwave radiation [PDF]

open access: yesمجلة التربية والعلم, 2013
In this study, the activated carbon has been prepared from sawdust and this was done by carbonization of sawdust at temperature of 350º C for 3 hours, after that treated with KOH at various ratios ranging from (0.5:1), (1:1), (1:2), (KOH: Carbonized ...

Coherent Plasma-Curvature Radiation in FRB [PDF]

open access: yes, 2018
Curvature radiation is a natural candidate for the emission mechanism of FRB. However, FRB spectra have structure with $\Delta \nu/\nu \sim \text{0.03--0.2}$, inconsistent with the very smooth spectrum of curvature radiation. Although this spectral structure might be attributed to chromatic scintillation or lensing, in four FRB high spectral resolution

Radiation with or without Antiandrogen Therapy in Recurrent Prostate Cancer

open access: yesNew England Journal of Medicine, 2017
Background Salvage radiation therapy is often necessary in men who have undergone radical prostatectomy and have evidence of prostate‐cancer recurrence signaled by a persistently or recurrently elevated prostate‐specific antigen (PSA) level.

TOMM20 as a driver of cancer aggressiveness via oxidative phosphorylation, maintenance of a reduced state, and resistance to apoptosis

open access: yesMolecular Oncology, EarlyView.
TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.
