Rio de Janeiro’s Integrated Command and Control Center (CICC-RJ ) has already seen duty in several large scale events which happened in town, some planned, others not. CICC-RJ is part of Rio de Janeiro state’s response to the Brazilian national government’s mandate to improve the state’s ability to anticipate and respond coherently to public safety events in the region. Its infrastructure is in...

We demonstrate attacks on the boot ROMs of the Nintendo 3DS in order to exfiltrate secret information from normally protected areas of memory and gain persistent early code execution on devices which have not previously been compromised. The attack utilizes flaws in the RSA signature verification implementation of one of the boot ROMs in order to overflow ASN.1 length fields and cause invalid f...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

Mechanically-driven syringes used to test peak expiratory flow (PEF) meters must produce the American Thoracic Society (ATS) standard waveforms with PEF accuracy of 2%. However, gas compression within the syringe could result in significant PEF inaccuracy when testing high resistance meters. The gas compression artefact was investigated in a mechanical syringe (PWG; MH Custom Design & Mfg L.C.,...

Photoacoustic imaging is based on the detection of generated acoustic waves through thermal expansion of tissue illuminated by short laser pulses. Fiber lasers as an excitation source for photoacoustic imaging have recently been preferred for their high repetition frequencies. Here, we report a unique fiber laser developed specifically for multiwavelength photoacoustic microscopy system. The la...

Objectives: Patellofemoral pain syndrome (PFPS) is one of the significant causes of knee pain that results in reduced functional performance.Interventional foot orthotics may lead to improvement in symptoms. In this study, the effects of custom-made foot orthoses with medial heel skive technique on pain and functional performance after four weeks were evaluated.  Methods: Fourteen subject...

INTRODUCTION Early humans probably used geothermal water that occurred in natural pools and hot springs for cooking, bathing and to keep warm. We have archeological evidence that the Indians of the Americas occupied sites around these geothermal resources for over 10,000 years to recuperate from battle and take refuge. Many of their oral legends describe these places and other volcanic phenomen...

In the present work, some MoS2 and WS2 nanosheets were prepared characterized. Depending on preparation procedures, trigonal prismatic (2H) or octahedral (1T) coordination of metal atoms obtained, exhibiting metallic semiconducting character. Both found large nonlinear optical (NLO) response, strongly dependent their So, character 2H-MoS2 2H-WS2 exhibit positive absorption strong self-focusing,...

DNA nanotubes offer a high aspect ratio and rigidity, attractive attributes for the controlled assembly of hierarchically complex linear arrays. It is highly desirable to control the positioning of rungs along the backbone of the nanotubes, minimize the polydispersity in their manufacture and reduce the building costs. We report here a solid-phase synthesis methodology in which, through a cycli...
