I compare gas-dynamical and stellar-dynamical models of collisions. These two models have distinctly different physics; for example , shocks introduce irreversibility in gas systems, while stellar systems evolve in a completely reversible fashion. Nonetheless, both models yield broadly similar results, suggesting that analogies between gas and stellar dynamics have some heuristic validity even ...

We analyze four recently proposed normal forms for elliptic curves. Though these forms are mathematically appealing and exhibit some cryptographically desirable properties, they nonetheless fall short of cryptographic viability, especially when compared to various types of Edwards Curves. In this paper, we present these forms and demonstrate why they fail to measure up to the standards set by E...

chapter attempting to synthesize the major themes of the section. The book also contains fourteen additional abstracts, many of which leave the reader frustrated but often interested enough to wish for considerably more detail about each study. Nonetheless, the major individual contributions are a most valuable and important collection of papers and well worth the attention of investigators in ...

In this study we consider neurophysiological aspects for the assessment of stress-related disorders. EEG Alpha Asymmetry could represent an effective method to be used in the virtual environment. Nonetheless, new protocols need to be defined. In this study herein, we present two methods and a case study.

A 20-year-old student under chronic stress developed a painful reddish left ear, vesicles on the left ear, severe left-sided peripheral facial-nerve palsy, and hypoesthesia of the left upper lip, after exposure to a ventilator. Ramsay Hunt syndrome was diagnosed. Instead of prednisolone she received dexamethasone (40 mg/d) but nonetheless recovered completely after 12 weeks.

Osteoid osteomas may be treated medically or surgically; both have similar long-term outcomes. Nonetheless, only surgery allows complete excision of the lesion for histological analysis. Excessive removal of surrounding bone may destabilise and weaken the bony structure and predispose it to fractures. We describe a surgical technique using a bone graft trephine to enable precise lesion removal ...

Cancer patients require care by a multidisciplinary medical team. Although nephrology usually is not the "core" specialty in such a multidisciplinary team, nonetheless it may substantially improve the quality of care. This paper reviews nephrologist's role in the management of the cancer patient.

We have recently defined "immunogenic modulation," a mechanism whereby malignant cells that survive anticancer therapy, due to sublethal delivery or development of treatment resistance, become nonetheless more sensitive to killing by cytotoxic T lymphocytes. This mechanism can be exploited to identify which therapies will best synergize with immunotherapy, potentially maximizing patient clinica...

Always granting that de novo mutations are possible, family history and biological characteristics are nonetheless crucial for the diagnosis of monogenic diabetes. We report here the case of two patients with monogenic diabetes in which the initial family history misled the diagnostic work-up and did not support the diagnosis. Family history details changed substantially after the molecular dia...

The term “biopsychosocial” has become quite fashionable in the low back pain industry. Nonetheless, many, if not most, spine care practitioners who employ the term do not appreciate the scope and limitations of the concepts involved, how they were evolved, or the responsibility they place on providers to change behaviors.
