Physical Review D, 1994 Cosmic balloons, consisting of relativistic particles trapped inside a spherical domain wall, may be created in the early universe. We calculate the balloon mass $M$ as a function of the radius $R$ and the energy density profile, $ (r)$, including the effects of gravity. At the maximum balloon mass $2GM/R\approx 0.52$ for any value of the mass density

Successful electrode insertion for spinal cord stimulation after balloon adhesiolysis in a patient with epidural adhesion - A case report - [PDF]
Anesthesia and Pain Medicine, 2021 Background Spinal cord stimulation (SCS) can be successfully performed using highly developed implantation techniques. However, anatomical barriers, such as epidural adhesion, may impede placing the electrode for SCS in an adequate position.

Characteristics of aerosols over Hyderabad in southern Peninsular India: synergy in the classification techniques [PDF]
Annales Geophysicae, 2012 The present study focuses on analyzing the seasonal changes in aerosol characteristics using a classification scheme proposed by Gobbi et al. (2007). This scheme is based on the correlation between the Ångström exponent (α) in the 440–870 nm range and

Thermodynamic structure of the convective boundary layer (CBL) over the Indian monsoon region during CAIPEEX campaigns [PDF]
Annales Geophysicae, 2017 Spatial and temporal variability in the convective boundary layer (CBL) height for the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) study period are examined using the data collected from high-resolution radiosondes ...

A “Floatilla” of Airborne Seismometers for Venus
Geophysical Research Letters, 2023 Barometers floating on high‐altitude balloons in the relatively clement cloud layer on Venus could detect and characterize acoustic waves generated by seismic activity, avoiding the need for high‐temperature electronics required for surface seismology ...

Model Investigations on Electric Discharges over Balloon-Borne Stratospheric VLF Antennas
Energies, 2022 Long linear antennas for very low frequency radio transmissions, supported by aerostats, unanchored, and raised to high altitudes, present themselves as slow-moving, highly conductive disturbances in cloud layers, acquiring an electrical charge and being

Apical ballooning without apical ballooning [PDF]
European Heart Journal, 2006 A 63-year-old woman presented with a sudden exacerbation of chronic obstructive lung disease and elevated levels of cardiac troponin T (0.5 ng/mL). The electrocardiogram exhibited sinus tachycardia, P-pulmonale, and diffuse T-wave inversion. The echocardiogram displayed markedly impaired left ventricular function.

Mission Architecture to Characterize Habitability of Venus Cloud Layers via an Aerial Platform
Aerospace, 2022 Venus is known for its extreme surface temperature and its sulfuric acid clouds. But the cloud layers on Venus have similar temperature and pressure conditions to those on the surface of Earth and are conjectured to be a possible habitat for microscopic ...
