Seismic techniques and suggested instrumentation to monitor volcanoes
First posted October 4, 2024 Changes in the pressure or location of magma can stress or break surrounding rocks and trigger flow of nearby waters and gases, causing seismic signals, such as discrete earthquakes and tremor. These phenomena are types of seismic unrest that commonly precede eruption and can be used to forecast volcanic activity.
Infrasound for volcano monitoring
First posted October 4, 2024 Volcanic eruptions produce acoustic waves when volcanic gases and hot material rapidly expand in the atmosphere.

Creating the necessary infrastructure for a trauma-informed system of care for children and youth
1. History and context 1.1. A brief review of the literature Much has been written on the importance of developing what has come to be called trauma-informed systems. Although an awareness that environmental events impacting the human condition has existed throughout recorded history, the genesis of this interest from a clinical perspective date back to research on the impact of war, initially in 1761, by the Austrian physician Josef Leopold (as cited in Trimble, 1985).
A first-principles understanding of point defects and impurities in GaN
I. INTRODUCTION AND BACKGROUND GaN is now an essential semiconductor material for applications including blue- and white-light emitting diodes (LEDs), lasers, and power electronics.1–31. S.

Deep levels in cesium lead bromide from native defects and hydrogen
Deep levels in cesium lead bromide from native defects and hydrogen Lead halide perovskites such as CsPbBr3 have achieved widespread attention as optoelectronic materials, due in large part to their good performance despite significant defect densities. This "defect tolerance" has often been explained by hypothesizing that there is negligible trap-assisted non-radiative recombination in these materials because none of the dominant defects give rise to deep levels in the gap.

Essential reading: Best GPS devices and tracking wearables for cycling If you’re a serious about this sport and don’t have a cycling app installed on your smartphone, you’re missing out on a lot. Cycling apps make it easy to keep tabs on speed, routes, workout duration, elevation and more.
Seismo-acoustic evidence for vent drying during shallow submarine eruptions at Bogoslof volcano, Alaska
Abstract Characterizing the state of the volcanic vent is key for interpreting observational datasets and accurately assessing volcanic hazards. This is particularly true for remote, complex eruptions such as the 2016–2017 Bogoslof volcano, Alaska eruption sequence. Bogoslof’s eruptions in this period were either shallow submarine or subaerial, or some combination of both.
Infrasound from giant bubbles during explosive submarine eruptions
Abstract Shallow submarine volcanoes pose unique scientific and monitoring challenges. The interaction between water and magma can create violent explosions just below the surface, but the inaccessibility of submerged volcanoes means they are typically not instrumented. This both increases the risk to marine and aviation traffic and leaves the underlying eruption physics poorly understood.

10 great GPS running watches for any budget
If you are a dedicated runner, there is no shortage of GPS running watches to choose from. They track everything from calorie burn to VO2 max. The feature packed devices are on the expensive side, while others are more affordable. Built-in GPS is important as it provides for more accurate location and distance information. It also renders you free from your phone. Such devices cost a bit more but are a real step up from most ordinary fitness trackers.
Armani Exchange Connected is the fashion brand's first touchscreen smartwatch

The new watch from the fashion brand fits a 1.2-inch AMOLED screen into a classic, premium watch design. As you’d expect, the display shows off Google’s Wear OS.
A GPS sports-watch called MARQ may be Garmin's next wearable
Garmin may have a completely new product lineup in the works. Its come to light that a US federal trademark registration was filed for the “MARQ” brand in June this year. The Garmin MARQ trademark is categorized as Computer & Software Products & Electrical & Scientific Products/Jewelry Products. Originally uncovered by Android Headlines, the trademark with the serial number of 88017457 was published on September 19th.
DreamOn: works with your body to activate natural, restful sleep
DreamOn is a new wearable designed to help you stop counting sheep and get some actual rest. Recently launched on Indiegogo, the wrist-based device calms your body and activates its natural sleep process. The brain emits a separate type of wave for each stage of sleep (awake, light sleep, deep sleep, etc.). When you go to bed these waves begin to slow as alertness relaxes and the mind drifts into slumber. This is known as slow wave non-REM sleep.

Caspase-8 Collaborates with Caspase-11 to Drive Tissue Damage and Execution of Endotoxic Shock
The execution of shock following high dose E. coli lipopolysaccharide (LPS) or bacterial sepsis in mice required pro-apoptotic caspase-8 in addition to pro-pyroptotic caspase-11 and gasdermin D. Hematopoietic cells produced MyD88- and TRIF-dependent inflammatory cytokines sufficient to initiate shock without any contribution from caspase-8 or caspase-11.
a beginners guide to interval training with wearables
You may not know this, but high-intensity interval training (HIIT) is a get-fit-quick scheme that works brilliantly well at burning fat. It is the perfect answer if you need to shake up your fitness routine and lose weight, but you don’t have any more time to devote to it. And guess what – you’re never too old for interval training. Studies have shown that HIIT changes muscles at the cellular level, boosting the energy producing capacity in the exercisers’ cells.
a no-fuss solution to tracking your underwater adventures
With MAZU, connecting your underwater adventures becomes simple. Using sensors and Bluetooth connectivity, the gizmo automatically tracks your dives. There are no buttons to press. Simply clip MAZU to your gear and it will automatically wake up and start logging as soon as you enter the water. Using depth, temperature, and motion sensors, MAZU dishes out data on dive time, max depth, mean depth, ascent rate, descent rate, temperature, calories burned, dive profile and more.
The next generation PUSH Band 2.0 introduces new ways to train
PUSH has announced the second generation of its workout tracking fitness band. In addition to your body, the Band can now be attached to gym equipment, too. The company promotes its strength band as the first scientifically validated wearable to provide true objective insights about your performance in the weight room. The idea behind PUSH is to take the guesswork out of lifting. A form of auto-regulation to help you achieve your workout goals and reduce the risk of injury.
Suunto's new fitness watch offers guided training and sleep quality insights
Suunto has launched its Fitness 3 sports watch. Announced earlier this year at CES 2018, this is both a personal training companion for active people and elegant timepiece for everyday use. “In design, we always rely on the key design elements of Suunto: robustness, accuracy and reliability, but with Suunto 3 Fitness, we wanted to look even further,” waid Suunto Design Manager Timo Yliluoma.
Boost your gym session with one of these workout trackers
While most activity trackers count steps, distance and calories, a limited few have been designed to make your gym workouts more effective. Doing a single exercise, like lifting a weight, is pretty easy. Doing an exercise well, on the other hand, is pretty hard. The majority of us want to exercise more, yet only 3% of the global adult population are documented gym members and more than 50% of gym members are not regular. Perhaps the latest crop of wearables can help change this.
