Constraining DM properties with SPI

open access: yes, 2007
Using the high-resolution spectrometer SPI on board the International Gamma-Ray Astrophysics Laboratory (INTEGRAL), we search for a spectral line produced by a dark matter(DM) particle with a mass in the range 40keV < M_DM < 14MeV, decaying in the DM ...

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

A Geomorphometric Approach to Estimate the Deterioration of Earthen Archaeological Sites by Rainfall and Diffusion Processes: The Huaca Chornancap (Eighth–14th Century ad), Lambayeque, Peru

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Rain‐induced erosion processes can severely damage Earthen archaeological sites. Huaca Chornancap (HCH; eighth–14th century ad) is a platform located in the Lambayeque region (Peru) exposed to seasonal rain due to El Niño Southern Oscillation (ENSO).

The INTEGRAL/SPI response and the Crab observations [PDF]

open access: yes, 2004
The Crab region was observed several times by INTEGRAL for calibration purposes. This paper aims at underlining the systematic interactions between (i) observations of this reference source, (ii) in-flight calibration of the instrumental response and ...

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK pathways

open access: yesArthritis &Rheumatology, Accepted Article.
Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Assessment of Multivariate Standardized Drought Index (MSDI) and Meteoro-Agricultural Drought Monitoring in Chaharmahal and Bakhtiari Porvince

open access: yesعلوم آب و خاک, 2020
Drought, as one of the most complicated natural events, causes many direct and indirect damages each year. Hence, single variable identification and monitoring of drought may not be appropriate enough for decision-making and management. In this study, in

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging. [PDF]

open access: yesJ Raman Spectrosc
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

Parenting Stress and Stressful Life Events Among Caregivers of Toddler Siblings of Autistic and Non‐Autistic Children

open access: yesAutism Research, EarlyView.
ABSTRACT This study measured experiences of parenting stress and stressful life events in caregivers of families with a toddler who has either an autistic or non‐autistic older sibling(s). Caregivers of toddlers (12–18 months old) with older autistic siblings (Sibs‐autism; n = 58) and toddlers with older non‐autistic siblings (Sibs‐NA; n = 46 ...
