The extended frequency response delivers a nearly perfect impulse response, and a nearly perfect phase response. At the other end of the audio spectrum, the low-frequency response extends below 0.1 Hz. The frequency response of the AHB2 extends beyond 200 kHz, to deliver the ultrasonic detail and fast transients captured by high-resolution recordings. The AHB2 is a the ideal match to the performance limits of high-resolution formats. The AHB2 delivers a noise performance and a frequency response that is well matched to the capabilities of DSD and 24-bit PCM formats. You will discover previously overlooked nuances, dynamics, and detail in your favorite recordings and experience the full potential of the latest high-resolution 24-bit PCM and 1-bit DSD audio formats. The dynamic range of the AHB2 is 130 dB, making it 10 to 30 dB quieter than the typical reference-quality power amplifier. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. High-Resolution audio is only as good as the weakest link in the playback system. Benchmark's goal was to build a power amplifier that could deliver the full performance of their flagship DAC2 converters, and today's finest high-resolution recordings. In most audio systems, the details captured by today's high-resolution 24-bit PCM systems are lost in a veil of amplifier noise and distortion. The differences between 16-bit and 24-bit recordings are inaudible when the power amplifier can only deliver 16-bit noise performance. Most power amplifiers cannot deliver the resolution provided by these converters and limit system noise performance to the equivalent of a 16 to 18-bit digital system. Benchmark DAC2 D/A converters outperform most high-end power amplifiers by very significant margins. High-resolution recording formats and converter technology have outpaced the development of improved power amplifiers. Power amplifiers are usually a weak link in the audio chain. – John Gatski, Everything Audio Network A New Benchmark "The Benchmark brings out nuances of reverb, quick percussive guitar attack with amazing clarity, but no over the top edginess.The -130 dB noise/dynamic range just gets us that much closer to the live music signature that we yearn to hear from our beloved electronics." "I very much enjoyed my time evaluating the Benchmark AHB2 amplifier and can heartily recommend it to those seeking one of the lowest distortion and lowest noise amplifiers on the planet – one that is very musically transparent and easy on the ears to boot." "As desired in a studio setting, the sonics from the AHB2 are neutral, and in my home setup, there is no observable emphasis in any particular frequency range." While costing only $2,995, it is hard to imagine asking for much more in a power amplifier." It is a technologically advanced and remarkable amplifier that can hang with any amp in its class because it is sonically transparent, images beautifully, and produces authoritative bass. "The Benchmark AHB2 embodies everything that a solid-state amp should. – SoundStage! Hi-Fi, Recommended Reference Component "If ever there were a giant-killer of an amp, this is it." – John Atkinson, Stereophile, Class A Recommended Component "This is an amplifier with very serious slam, and – even better for those with less sensitive speakers, big rooms or just a hankering for 'just in front of the PA stack' listening levels – it keeps it all together however loud you decide to play things." – Paul Seydor, The Absolute Sound, 2019 Golden Ear Award I can't recall why I didn't purchase the loaner when I reviewed, but that has since been rectified: The AHB2 is now my reference amplifier." "There's nothing here to inspire cults, 'merely' a precision instrument that performs the precisely defined task of reproducing music and sound essentially to perfection. With AHB2, you'll finally hear what you've been missing in high-resolution playback. Significantly quieter than typical reference amps, the Stereophile Editors' Choice Award-winning and Class A Recommended AHB2 touts extremely extended frequency response at both spectrums, patented error-correction technology, remarkable efficiency, a bi-polar Class AB output stage, and an innovative power supply. Given Benchmark's sterling reputation with digital audio, it's not surprising the company has built a groundbreaking power amplifier, AHB2, capable of delivering the full performance of its flagship converters and the world's finest high-resolution recordings. Benchmark AHB2 Power Amplifier Reveals Full Scope of PCM and DSD Recordings: Extended Frequency Response, Class AB Output Stage, Patented Technology, Remarkable Efficiency

# and have 2 and 3 different commits each, respectively. git push -u Alternatively, you can use the set-upstream option that is equivalent to the -u option.# Your branch and 'origin/development' have diverged, The easiest way to set the upstream branch is to use the git push command with the -u option for upstream branch. Git tells you about this right in the output for "git status": $ git status When youre satisfied, push it to your remote repository. What you are wanting to do is track a remote branch, which is done with git branch -set-upstream-to or more simply git branch -u. git branch -set-upstream-to sets a branch to be tracked by the branch in the remote repository specified. This information helps tremendously in staying up-to-date. When you want to share some work with the upstream maintainers you branch off main, create a feature branch. git remote add creates a remote, which is a shorthand name for another repository. (b) if there are 4 commits on the remote upstream branch which you haven't pulled yet, then your local branch is "4 commits behind" its upstream branch. (a) if you have 2 commits in your local repository which you haven't pushed to the remote yet, then your local branch is "2 commits ahead" of its upstream branch. Git can now also tell you about unsynced commits which you haven't pushed or pulled, yet. With an upstream branch set, you can simply use the shorthand commands "git pull" and "git push" - instead of having to think about the exact parameters like in "git push origin development". This relationship is very helpful for two reasons: Let's also say that you've set the remote "origin/development" as its upstream branch. Let's say that your current local HEAD branch is named "development". Why should you set up an upstream branch for a local branch? If you already have a local branch and want to set it to a remote branch you just pulled down, or want to change the upstream branch youre tracking, you can. In practice, however, in makes lots of sense to see them as counterparts - connected in a so-called "tracking connection". Interested in learning more?

Using Snyk with GitHubĬontinuously perform security scanning across all the integrated repositoriesÄetect vulnerabilities in your open source components The next time I want to push changes I can just use git push without any parameters. Now the local branch also has a remote counterpart. When I want to push my changes, first I have to use -u or -set-upstream like this: If youâre on a local branch myNewFeature and want to share this branch remotely you have to set the upstream to make it a remote branch. How do I turn my local branch into a remote branch? This can be different, for instance, when you are working with multiple remotes. Note that origin is the standard reference to the original remote repository my project was cloned from. Your local branch name, myLocalName will be connected to the remote branch remoteName. Git checkout -b myLocalName origin/remoteName If you would check out a remote branch but name it differently on your local machine you can run: This means that there is a local copy of the branch available on your machine. How do I create a local branch from a remote branch?Īfter a fetch, you can check out the remote branch as mentioned earlier. Now all you need to do is use git checkout. This command downloads the references from your remote repository to your local machine, including the reference to the remote branch. If you want to check out a remote branch someone published, you first have to use git fetch. It is good to mention that git checkout remote branch is not an actual existing command. How do I checkout a remote branch?Ī remote branch is the best way to share your development work with other people in your team. It totally makes sense to do this in a separate level branch that originates from your feature branch. This might sound weird, but imagine you are creating a new feature in a new branch and you want to experiment a bit. Knowing this, you can also make a branch from a branch recursively. Note: when you check out a branch on your local machine, all commits will be on the new branch and not on the main. If you want to work in this branch and commit to it, you need to check out this branch just like before using git checkout dev. When you want to create a new branch from your main branch with the name âdevâ, for example, use git branch dev-this only creates the branch. If you already have a branch on your local machine, you can simply check out or switch to that branch using the command git checkout. But it’s still a mystery exactly when and how harm starts to accrue for different species as radiation levels increase. Normal background radiation levels aren’t usually harmful, because living things have biological mechanisms in place to prevent and repair small levels of damage, explains Kathryn Higley, a health physicist specializing in radioecology at Oregon State University. Today, radiation levels are generally below what would induce acute radiation sickness and range from 0.4 millisieverts per hour in the Red Forest - thousands of times higher than background levels and dangerous to live in - to levels even lower than typical background radiation. The radionuclide iodine-131, for instance, vanished by the summer of 1986, leaving slower-decaying ones like cesium-137 and strontium-90 scattered unevenly across and within the zone’s soils, vegetation, fungi, and animals. The 1,600-square mile exclusion zone around the plant has remained largely devoid of people since the accident.Īs time passed and the most dangerous radionuclides decayed, the zone became less inhospitable. The area with the trees’ skeletal remains is now called the Red Forest. A 600-hectare patch of pine trees died, along with many resident mammals and invertebrates in the area. Over subsequent decades, thousands of children and adolescents who likely absorbed somewhat lower doses developed thyroid cancer, a cancer type that, fortunately, most tend to survive.įlora and fauna also suffered in the initial aftermath. More than two dozen first responders died within months after rapidly absorbing doses of up to 13,400 millisieverts (a sievert is a unit of radiation absorption normal background radiation levels are usually around 1.5 to 3.5 millisieverts a year.) When a safety system test at one of the Chernobyl power plant’s reactors went badly wrong in April 1986, explosions unleashed a fiery plume of debris and radioactive atoms, or radionuclides, into the air that, over several days, may have emitted several hundred times more radiations than the atomic bomb dropped on Hiroshima. Universal History Archive/Universal Images Group/Getty Images Immediate falloutĬhernobyl’s “Elephant’s Foot” is still radioactive today - after the initial meltdown, a few minutes of being near it would have been fatal. Examining why scientists reach different conclusions, and how recent research shines new light on the debate, gets us closer to the answer. Radiation levels around Chernobyl have plummeted since the initial accident, but creatures that have reclaimed the area remain chronically exposed to low levels.įiguring out whether this radiation causes harm - and if so, how and how much - is critical to understanding not just how the largest nuclear accident in history changed the environment, but also how chronic, low-level radiation affects living things generally. At the heart of the debate is not so much whether chronic radiation has any effect on living things, but at what dose the effects become significant. Ultimately, “there’s a grain of truth in all of these studies,” says David Copplestone, a radioecologyst at the University of Stirling in Scotland. This controversy has only sharpened in recent years. But other scientists have found mostly negative effects of radiation on the health and abundance of creatures, from birds to mammals, with many populations smaller in more heavily contaminated areas. Some scientists have documented thriving wildlife now that people have left, suggesting that lingering radioactive contamination doesn’t pose a significant threat. In fact, a debate roils in the scientific literature about the health of the microbes, fungi, plants, and animals that live around Chernobyl. But to some scientists, nature isn’t doing as well as it seems. Photos show foxes roaming the buildings of abandoned towns and bison and wild horses flourishing after people were permanently evacuated. Thirty-five years after the meltdown at the Chernobyl nuclear power plant in northern Ukraine reports often portray the area as a paradise for wildlife. Preventing early postoperative arm swelling and lymphedema manifestation by compression sleeves after axillary lymph node interventions in breast cancer patients: A randomized controlled trial. Nighttime compression supports improved self-management of breast cancer-related lymphedema: A multicenter randomized controlled trial. Prevention of arm lymphedema through the use of compression sleeves following breast cancer: Results from a targeted literature review. How to use and care for your compression sleeve.You can learn more about how we ensure our content is accurate and current by reading our editorial policy. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. According to the results, compression sleeves may reduce the risk of lymphedema after breast cancer treatment or prevent it from getting worse. A 2020 review involved participants who had received a sentinel node biopsy, an axillary lymph node dissection, or radiotherapy as treatment for breast cancer.It also led to significant improvement in certain quality-of-life measures, such as fatigue, pain, physical functioning, and arm and breast symptoms. A small 2019 study of breast cancer survivors found that wearing a compression sleeve for 2 years helped prevent postoperative lymphedema. Participants who wore a sleeve for 8 to 10 hours daily experienced less postsurgery swelling and had less arm edema at 3, 6, 9, and 12 months after the surgery. A 2017 study examined the benefits of compression sleeves after axillary lymph node dissection - a breast cancer surgery that can damage the lymphatic system.They may also help prevent this condition by stopping lymph from pooling.Ĭompression sleeves may have long lasting benefits. Since these sleeves apply pressure, they help encourage lymph fluid to drain away from the tissue, Younus says, which can reduce pain and swelling.īut these sleeves don’t just treat symptoms of lymphedema, Younus explains. The main goal of lymphedema treatment is to manage the swelling caused by excess lymph fluid buildup. Differences in male age structure among catchments of varying disease status were consistent with the hypothesis of higher adult male mortality rates and turnover in currently affected catchments. The demographic group most commonly affected by mucormycosis was confirmed to be adult males. This study also provided the first evidence of population level consequences of disease in platypuses. Adult males had higher fat stores than adult females, especially during winter. Differences in platypus morphometrics within and between catchments and seasonal moulting patterns were detected. Sampling focussed on assessing variability within and between river catchments and compared populations in river catchments with contrasting disease status. The sex, age, body size, tail volume index, health and moult condition of 195 individuals were assessed, and population age and sex structures characterised. Extensive live-trapping surveys were conducted from January 2008 to July 2009 in 75 streams and 18 river catchments across Tasmania including King Island. The hypothesis of higher mucormycosis prevalence and mortality in adult males was also investigated. It also sought to identify important spatial scales of natural variability and the magnitude of seasonal variation in platypus body size, condition and population structure. mographic patterns in Tasmanian platypuses to provide a basis for investigating impacts of mucormycosis or other anthropogenic disturbances. Although the ulcerative fungal disease mucormycosis has infected platypuses in Tasmania for three decades, its population level impacts and conservation significance remain unknown. This hampers impact assessments and understanding of platypus ecology. Despite widespread interest in platypus (Ornithorhynchus anatinus) conservation, it is unclear how their fundamental morphometric and demographic characteristics differ over a range of scales.

Because time doesn't overlap it is relatively easy to accidentally overwrite a days worth of entries if you accidentally meant to make your start time of an entry to 3:00 PM, forgetting to add the "PM", and the system defaults to 3:00 AM, and giving you a quick "are you sure message". The desktop application hasn't always been that reliable (crashes, the window opening) although I still run it in the background to monitor what I'm working on, so I can go back and review it at any time. The project selection tool starts to get slow to load when you have a lot of projects in the system. Time is linear, and cannot overlap so if you need to go back and change your time because it wasn't tracked properly, you don't need to worry about readjusting all entries to make sure you're not double billing a client. It's easy to create a budget for a project that can be assigned to either time or a monetary value.

If you feel that your report lacks some tasks you finished, you can always review and rewrite you reports for a more accurate summary. Nonetheless, you can also fix your reports even after the period you have worked on. You can also choose as to how your summary reports will be shown-will it be by projects, by tasks, by team or by whole. You can actually enumerate the different tasks you have worked on within your preferred timeline(hour/day/week/year). What I like most about it is its simplified yet detailed reports on a chosen time period. But as I understand its real purpose, I then started enjoying its use especially on summary reports. At first, I doubted its capability as time tracker as I was confused on how to use it. It also helps me to easily connect with the client.

With a 4.4 out of 5 rating from almost 2 million reviews on the Google Play Store, this sudoku app is clearly popular. Good Sudoku stands out for a few reasons. In the past you’d be stuck holding a Sudoku book or maybe you could find it in the puzzle section of the newspaper, but normally you’d have to take something with you specifically to enjoy a good game of Sudoku. If you like puzzle games you’ve likely played Sudoku before. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. The maximum collector current of the 2N2222 is 800mA, whereas the bc547's is 100mA.īoth the 2N2222 and the BC547 have the same power dissipation (500mw), the 2N2222 has a DC gain of 75 to 300HFe and the BC547 has a DC gain of 110 to 800HFe, and the 2N2222 has a thermal resistance of 146k/w and the BC547 has a thermal resistance of 83.3 C/w.īecause the transition frequency of 2N2222 is 250MHz and that of BC547 is 300MHz, the noise figure on 2N2222 is 4db and on BC547 is 10db.2N2222 is a semiconductor device used to amplify or switch electronic signals and electrical power. The voltage between the emitter and the base is 5 volts in 2N2222 and 6 volts in BC547. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547. The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. The BC547 transistor came in a to-92 package, but 2N2222 transistors, such as the PN2222 and KN2222, also came in to-92 packages. The 2N transistors were packaged in a to-18 package, which means they were enclosed with metal. The 2N2222 transistor is more powerful than the BC547. The BC series, such as BC549 and BC639, are the finest recommendations for the BC547 transistor equivalent, followed by the 2N2222 transistor.īC636 replaces BC547, 2N2369, 2N3055, 2N3904, 2N3906, and 2SC5200 in the PNP.ĢN3904, BC547, BC548, and 2N3906 are 2N2222 comparable transistors.Įach of the 2N2222 equivalent transistors described here is an NPN bipolar transistor, with the majority of them being identical. Package TO-92 TO-18 BC547 vs 2N2222 Equivalents When the switch is closed, the transistor starts working, and the resistor value regulates the LED ON/OFF interval. In the circuit, the 2N2222 transistor is shown as a switch, with an input resistor driving it and a second resistor driving the LED. You can also use a timer to control when the LED turns on and off. The schematic depicts the basic circuit of the BC547 as a switch, which contains two resistors for driving LEDs and a transistor bias terminal.Ĭurrent flows across the circuit when the switch is closed, and the transistor serves the function of a switch. This one has a higher gain due to the transistor architecture. The best voltage amplifier circuit that uses the NPN 2N2222 transistor is the common emitter arrangement. The diagram depicts an amplifier circuit using a 2N2222 transistor. The input resistor and capacitor will be used as bypass components, with the resistor acting as a biasing agent for the BC547 transistor.Īs a result, an audio signal received at the input is amplified and sent to the output speaker by the transistor. The diagram depicts a basic amplifier circuit that uses BC547 and only has four components.

Go to Start menu search bar, type in ‘device manager,’ and select the Best match. As soon your PC powers up from the next reboot, the CHDSK scan will be launched, and it will give you the state of your drive’s health. Then, type the following command in the Command prompt and hit Enter: Chkdsk /fĪs soon as you hit the Enter key, the command will get executed, and you’ll be asked for setting up the scan after the next reboot. To get started with CHKDSK, first launch the Command prompt as shown in the first method above. And unsurprisingly, you can use this command for examining the hard drive health of your Windows 11. It is available in almost all Windows operating systems. Further, it also goes over your disk sectors and marks the malfunctioning ones as ‘bad,’ before trying to salvage any information it can. It will run in a couple of seconds, giving you the status of your hard disk’s health status as it is.Īnother utility in the Command prompt toolbox, the CHKDSK command, short for ‘check disk’, as its name suggests, helps you in checking and fixing your hard disk bugs. The tool will be launched as soon as you hit enter. In the WMIC interface, type the following and hit Enter: diskdrive get status In the Command prompt, type in ‘wmic,’ and hit Enter. Go to the Start menu search bar, type in ‘command prompt,’ and select the Best match. WMIC, short for Windows Management Instrumentation Command, is a command-line tool that helps you check and manage your Windows tasks, such as performing a health check of your hard disk. Let’s get started with built-in Windows tools first. We’ve covered both the approaches: manual and automated. There’s also an option to resort to third-party options. And some of these come in handy in checking your hard disk’s state. The Windows operating system comes packed with a host of applications that cater to all kinds of computer problems. In this article, we’ve tried to cover the exact methods you can follow for that. But, it’s important that you keep a close watch on its health, so you can avoid any insusceptible crash and the resulting data loss it would bring. The real-time activity of the disk is also displayed and updated periodically.Don’t worry if your PC is fairly new, though it won’t be going bust anytime soon. These areas can be removed to reveal the data hidden within these areas.ĭiskCheckup also displays device information, such as the drive geometry, serial number, model number, media rotation rate, and supported features. The HPA/DCO are hidden areas of the hard disk that contain data not accessible by the user. The results of these tests are displayed in DiskCheckup.ĭiskCheckup can detect and set the sizes of the Host Protected Area (HPA) and Device Configuration Overlay (DCO). There are two main self-test routines: Short Test and Extended Test. DiskCheckup monitors these changes over a long period and predict the date (if available) of the Threshold Exceed Condition (TEC), which is displayed on the main window.ĭiskCheckup can also execute built-in Disk Self-Test (DST) routines implemented by the vendor to detect drive failures. Note that SMART attributes change slowly over time and are helpful attempts to diagnose the life span of a particular drive. If an attribute drops below its threshold, the drive cannot guarantee that it will be able to meet its specifications in the future. SMART monitors elements of possible long term drive failure, such as 'Spin Up Time', the number of start/stops, the number of hours powered on and the hard disk temperature.ĭiskCheckup displays the current values of the SMART attributes, along with the Threshold value for that attribute. If SMART is enabled on a hard disk, the system administrator can receive analytical information from the hard drive to determine a possible future failure of the hard drive.
