Heavy precipitation episodes and cosmic rays variation [PDF]

open access: yesAdvances in Geosciences, 2006
In this paper an attempt is made to investigate the possible temporal correlation between heavy precipitation episodes and cosmic rays' activity, on various time scales.

Results from the CERN pilot CLOUD experiment [PDF]

open access: yes, 2009
During a 4-week run in October–November 2006, a pilot experiment was performed at the CERN Proton Synchrotron in preparation for the Cosmics Leaving OUtdoor Droplets (CLOUD) experiment, whose aim is to study the possible influence of cosmic rays on ...

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

open access: yesJournal of Raman Spectroscopy, EarlyView.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

The AMS-02 Cosmic-Ray Deuteron Flux is Consistent with a Secondary Origin

open access: yesThe Astrophysical Journal Letters
The recent measurements of cosmic-ray (CR) deuteron fluxes by AMS-02 show that the rigidity dependence of deuterons is similar with that of protons but flatter than ^3 He, which has been attributed to the existence of primary deuterons with abundance ...

Discriminating Chemoresistant and Chemosensitive Tubo‐Ovarian High‐Grade Serous Carcinoma Cells With Raman Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Confocal Raman microscopy combined with multivariate analysis distinguishes cisplatin‐resistant and ‐sensitive tubo‐ovarian high‐grade serous carcinoma cell lines. ABSTRACT Chemoresistance is a major obstacle to effective cancer treatment, particularly in tubo‐ovarian high‐grade serous carcinoma (HGSC), the most lethal gynaecological malignancy ...

TeV astronomy of millisecond pulsars [PDF]

open access: yes, 1991
This thesis is concerned with the detection of pulsed TeV γ-rays from millisecond pulsars. These stars appear to include some very efficient producers of high energy particles, but the mechanisms by which they produce TeV γ-rays are still a matter of ...

Precision Measurement of Cosmic-Ray Nitrogen and its Primary and Secondary Components with the Alpha Magnetic Spectrometer on the International Space Station [PDF]

open access: yes, 2019
A precision measurement of the nitrogen flux with rigidity (momentum per unit charge) from 2.2 GV to 3.3 TV based on 2.2×106 events is presented. The detailed rigidity dependence of the nitrogen flux spectral index is presented for the first time.

Rapid and quantitative phage susceptibility test by ramanome

open access: yesmLife, EarlyView.
Abstract Antimicrobial resistance poses an escalating global threat, renewing interest in bacteriophage therapy as a precision alternative to antibiotics. However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective ...

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.
