121. A copyright protection scheme for digital images based on shuffled singular value decomposition and visual cryptography (PubMed)

into blocks of same size after shuffling it and then the singular value decomposition is applied to each randomly selected block. Shares are generated by comparing one of the elements in the first column of the left orthogonal matrix with its corresponding element in the right orthogonal matrix of the singular value decomposition of the block of the low frequency sub-band. The experimental results show that the proposed scheme clearly verifies the copyright of the digital images, and is robust (...) A copyright protection scheme for digital images based on shuffled singular value decomposition and visual cryptography This paper proposes a new watermarking algorithm based on the shuffled singular value decomposition and the visual cryptography for copyright protection of digital images. It generates the ownership and identification shares of the image based on visual cryptography. It decomposes the image into low and high frequency sub-bands. The low frequency sub-band is further divided

The effect of blue-light blocking spectacle lenses on visual performance, macular health and the sleep-wake cycle: a systematic review of the literature. Blue-blocking (BB) spectacle lenses, which attenuate short-wavelength light, are being marketed to alleviate eyestrain and discomfort when using digital devices, improve sleep quality and potentially confer protection from retinal phototoxicity. The aim of this review was to investigate the relative benefits and potential harms

-six cases were treated using extension block pinning (surgery group) and 23 were treated nonsurgically (nonsurgical group). At the final follow-up, extension lag and flexion of the DIP joint of the affected digit were measured. Distal interphalangeal joint pain was rated using a visual analog scale and the overall clinical outcomes were graded using Crawford's criteria. Complications, including nail deformity and dorsal prominence, were also assessed. The rate of DIP joint subluxation and fracture (...)

the controversial . Might they or their ministerial team have coined the term? Tellingly, the 1986 research paper mentioned bed blocking’s effect on staff: “Nurses in one acute medical ward complained of having to be constantly vigilant to prevent ambulant demented patients from wandering and getting lost. On another ward so many patients were awaiting transfer to a long stay geriatric bed that the ward sister voiced her intention to resign.” All the more reason to ban its use. David Payne is digital editor (...) David Payne: “Bed blocking” is an offensive term David Payne: "Bed blocking" is an offensive term - The BMJ ---> Simon Stevens, head of the NHS in England, from hospital could continue for up to five years because of social care pressures. His comments were immediately reported as a “bed blocking” crisis. The term bed blocking certainly trips off the tongue more easily than “delayed transfers of care,” but is the term derogatory? I think it is, implying that one patient is somehow denying

130. Pulse-train Stimulation of Primary Somatosensory Cortex Blocks Pain Perception in Tail Clip Test (PubMed)

Pulse-train Stimulation of Primary Somatosensory Cortex Blocks Pain Perception in Tail Clip Test Human studies of brain stimulation have demonstrated modulatory effects on the perception of pain. However, whether the primary somatosensory cortical activity is associated with antinociceptive responses remains unknown. Therefore, we examined the antinociceptive effects of neuronal activity evoked by optogenetic stimulation of primary somatosensory cortex. Optogenetic transgenic mice were (...) subjected to continuous or pulse-train optogenetic stimulation of the primary somatosensory cortex at frequencies of 15, 30, and 40 Hz, during a tail clip test. Reaction time was measured using a digital high-speed video camera. Pulse-train optogenetic stimulation of primary somatosensory cortex showed a delayed pain response with respect to a tail clip, whereas no significant change in reaction time was observed with continuous stimulation. In response to the pulse-train stimulation, video monitoring

to the coracoid approach.A total of 100 adult patients who received IBPB block for upper limb surgery were randomized into two groups: a coracoid approach group (group C) and a retroclavicular approach group (group R). In group C, the needle was inserted 2 cm medial and 2 cm inferior to the coracoid process and directed from ventral to dorsal. In group R, the needle insertion point was posterior to the clavicle and the needle was advanced from cephalad to caudal. All ultrasound images were digitally stored (...) Comparison of the coracoid and retroclavicular approaches for ultrasound-guided infraclavicular brachial plexus block. This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared

Paramedic-Performed Digital Nerve Block To Facilitate Field Reduction Of A Dislocated Finger. This short report describes the use of digital nerve block by a paramedic to facilitate the reduction of a dislocated finger in the prehospital setting. The finger was successfully reduced at the scene without requiring administration of parenteral opioids. The patient was reluctant to visit an emergency department, but was able to be referred to a local primary care practice for postreduction imaging (...) and further care. Paramedic-performed local and regional anesthesia has not been previously described in the emergency medicine or emergency medical services literature. With appropriate training, prehospital digital nerve blocks may be a feasible option to supplement existing paramedic analgesic options.

A comparison of strength for two continuous peripheral nerve block catheter dressings Despite the benefits of continuous peripheral nerve blocks, catheter dislodgment remains a major problem, especially in the ambulatory setting. However, catheter dressing techniques to prevent such dislodgment have not been studied rigorously. We designed this simulation study to test the strength of two commercially available catheter dressings.Using a cadaver model, we randomly assigned 20 trials to one (...) of two dressing techniques applied to the lateral thigh: 1) clear adhesive dressing alone, or 2) clear adhesive dressing with an anchoring device. Using a digital luggage scale attached to a loop secured by the dressing, the same investigator applied steadily increasing force with a downward trajectory towards the floor until the dressing was removed or otherwise disrupted.The weight, measured (median [10th-90th percentile]) at the time of dressing disruption or removal, was 1.5 kg (1.3-1.8 kg
