The number of security vulnerabilities, breaches and digital disaster increases over time. One important source of weaknesses in computer networks is the ubiquitous flaws (‘bugs’) in the software, which are exploitable by malicious agents. Consequently, “patching” the software to correct known bugs is becoming more important, especially for network-based systems. However, decision makers often ...

no value in the prevention of headache. Treatment of established headache after lumbar puncture includes hydration, analgesics, vasopressin, and caffeine. More invasive techniques include the installation of saline or autologous blood into the epidural space. The latter procedure (epidural blood patching) has a success rate of 90% with only minor short term sequelae. Very few of the departments...

AIM The purpose of this study was to systematically review clinical studies examining the survival and success rates of implants placed with intraoral onlay autogenous bone grafts to answer the following question: do ridge augmentations procedures with intraoral onlay block bone grafts in conjunction with or prior to implant placement influence implant outcome when compared with a control group...

Cell therapy, while retaining promise for cardiac regeneration, has thus far been encumbered by variable and unpredictable fates of delivered cells. In a recent issue of PNAS, Godier-Furnémont and colleagues describe a new strategy to regulate cell delivery by promoting specific migration and growth factor secretion behaviors of implanted cells from a decellularized matrix via biochemical preco...

Stochastic partition models tailor a product space into a number of rectangular regions such that the data within each region exhibit certain types of homogeneity. Due to constraints of partition strategy, existing models may cause unnecessary dissections in sparse regions when fitting data in dense regions. To alleviate this limitation, we propose a parsimonious partition model, named Stochast...

BACKGROUND AND AIM To assess the success rate of implants placed in atrophic ridges, regenerated by means of block bone grafts harvested from iliac crest, calvaria or intraoral donor sites (mandibular ramus, chin). METHODS AND MATERIALS A systematic review of all prospective and retrospective studies analyzing the success rate of implants placed simultaneously or as a second surgery following...

Performance requirements of the patch repair material are strength, size stability, shieldability, durability, bond property with the substrate concrete, ductility and so forth. Various kinds of patch repair materials with short fibers have been developed and used. Engineered Cementitious Composites (ECC) which provides multiple cracking and strain hardening behavior is also one of the attracti...

OBJECTIVE To investigate the effectiveness of voluntary trunk rotation and half-field eye-patching to treat patients with unilateral neglect in stroke. DESIGN Pre-post, day 60 follow-up, single-blinded randomized controlled trial. SETTING Single-centre inpatient rehabilitation hospital. SUBJECTS Sixty subacute patients with right hemisphere stroke having unilateral neglect within eight we...

We describe proof planning: a technique for both describing the hierarchical structure of proofs and then using this structure to guide proof attempts. When such a proof attempt fails, these failures can be analyzed and a patch formulated and applied. We also describe rippling: a powerful proof method used in proof planning. We pose and answer a number of common questions about proof planning a...
