![]() WHY they have this zig-zag color pattern, though, is a whole other “Mundane Mystery” for another time, since scientists aren’t really sure why zebras look like they do (though I think we can all agree that the zebra stripe is the most stylish in nature). ![]() So, what’s the final answer to our question? Well, if we’re talking genetically, zebras grow black hair by default, so that makes them black with white stripes. Most animal skin cells produce melanin, which gives human skin, eyes, and hair their color. ![]() Underneath the zebra’s striped coat is actually black skin. A good portion of a zebra’s melanocytes create its high-in-melanin black fur, which makes up about half of its coat, while other melanocytes are, in essence, “turned off”, and produce a zebra’s white hairs (which contain no melanin). A popular question about zebras is whether they are white with black stripes or black with white stripes. The melanocytes in zebra fur follicles ultimately determine whether particular strands will be dark or light based on where they are on the body. The real answer is found in a group of zebras’ cells called melanocytes, which produce the pigment melanin that gives zebra hair its color (and not only zebras, but all animals’ hair & skin). At first glance, it may seem the opposite - after all, the black lines of many zebras end up on the belly and towards the inside of the legs, revealing the rest as white. You will be surprised to know that certain. One of the most logical answers behind why zebras have black and white stripes is protection from biting flies, thermoregulation, and protection from predators. So, is that it then? They’re white with black stripes? Nope, not quite. Zebras are believed to be white with black stripes most of the body of the animal is covered in black stripes. Are zebras born with black stripes or white stripes Whats important about zebras is that their white fur represents an absence of melanin white is not its. The majority of zebra hair is white, including the hair on their bellies & the inner parts of their legs (which is where their stripes seem to diminish). But that doesn’t necessarily mean their stripes are white on black. And it all comes down to zebra hair microbiology, where their dual-colored pattern originates.īeneath their fur, zebras are actually black skinned. When zebras got loose in Prince Georges County recently, the fiasco brought a great question into the light: are zebras black with white stripes, or white with black stripes? I know, it sounds a bit philosophical, but there actually is a definitive scientific answer. ![]()

If you want to eliminate dark spots (like specks of dust on the sensor), shoot against a bright white background. In order to create a map of hot pixels, please use dark or black background - for instance, take a picture with the lens cap on. Helicon Focus has a Dust map feature designed to deal with dust spots and hot pixels. Typically these artifacts come from dust particles or hot pixels on the source images that turn into this kind of pixel streaks on the output during processing.

When possible, incorporate the job post title as well.Īvoid overused phrases. ![]() This will help to grab the attention of both human and computer readers. Ideally, your resume headline will include keywords from the job posting. ![]() In other words, capitalize the first letter of major words, so your headline immediately stands out as the title of your resume. Your professional headline should be in bold font at the top of your resume and use title case. It’s job is to stand out by combining key information (role and level) with a personality/talent/skills descriptor (“Passionate”, “Diligent”, “Creative”, “Award-Winning”, etc.) However, anything longer than a brief phrase defeats the purpose. If needed, some phrases might be a bit longer to align with the job description and fully highlight your value. The resume headline needs to be a clear, concise, and to-the-point phrase of about three to five words. It’s a red flag for recruiters if your headline is out of sync with the position they are hiring for, which means your resume will likely go into the trash pile. It takes a bit more effort, but it’s important to tailor your resume to fit each job for which you’re applying. Incorporate some of those into your resume headline.Įdit your headline for each job application. Review the job post and identify the skills, competencies, and experience required that you possess. For example, “Driven Marketing Analyst” or “Innovative Human Resources Manager.”Īlign it with the position. Example title levels include assistant, junior, senior, manager, director, and specialist. Next, after your adjective, include a description of your position and level. Examples of appropriate adjectives for your headline might include driven, proven, successful, innovative, or motivated. You don’t want to brag or overdo it, but you do want to begin your resume by making a statement regarding your value. As you write your headline, use an adjective that puts you in a positive light. However, even inexperienced people starting out in their careers can utilize a headline to showcase competencies and attributes that make them a potential fit. As an experienced professional, your headline can quickly stand out from the competition in the eyes of recruiters and hiring managers. ![]() ![]() ![]() ![]() "Discovering an ancient coffee machine is especially hilarious." Discovering an ancient coffee machine is especially hilarious. What's even better in Rising Tide though is how discovering Old Earth artifacts adds to your knowledge of what happened to Old Earth. Just as it was with Alpha Centauri and Beyond Earth, Firaxis have done their homework and each faction, leader and technology has a fleshed-out story behind them. Factions such as the North Sea Alliance (NSA) also bring better colonisation technology such as floating cities (which gives them the ability to start the game with an ocean city). Rising Tide is actually meant to be set an undefined number of years after the first wave of colonists have made planetfall and consists of factions that were more focused on fixing Old Earth instead of running away from its problems (such as INTEGR and North Sea Alliance) or decided to leave too early before better propulsion technology was developed (such as Al Falah who left on generation ships instead of cryogenic "sleeper" ships). So is the expansion pack as good as the Steam user reviews make it out to be (83% of 404 reviews) or have they irrevocably ruined the original formula? After purchasing the expansion pack and playing for about 24 hours (which consisted of a few games in single player and multi player) I am now ready to review it. So when Firaxis announced they were releasing an expansion pack called Rising Tide, I was pretty excited. Consequently the game rated well on Choicest Games, receiving an 8/10. Despite the game not being the next Alpha Centauri I liked the hard science-fiction backdrop, the epic soundtrack, the greater Civ customisation options and the non-linear tech tree. When the base game Beyond Earth was released the game received positive reviews from the critics but received mixed reviews from the gaming public with a 52% (Mixed) rating on Steam from over 13,000 reviews. ![]() ![]() ![]() doi: 10.1002/ has been revolutionizing electronics since October 2004 when Andre Geim and Kostya Novoselov first determined how to remove a single layer of carbon lattice from graphite. "Dual-mode orgnic electrochemical transistors based on self-doped conjugated polyelectrolytes for reconfigure electronics". ^ Nguyen-Dang, Tung Visell, Yon Nguyen, Thuc-Quyen (May 2022).Fundamentals of III-V Semiconductor MOSFETs. "The silicon insulated-gate field-effect transistor". "Evolution of the MOS transistor-from conception to VLSI" (PDF). In 2022, the first dual-mode organic transistor that behaves in both depletion mode and enhancement mode was reported by a team at University of California-Santa Barbara. ![]() Kunig at Westinghouse Electric fabricated enhancement- and depletion-mode indium arsenide (InAs) MOS thin-film transistors (TFTs). In 1963, both depletion- and enhancement-mode MOSFETs were described by Steve R. Hofstein and Fred P. Heiman at RCA Laboratories. The first MOSFET (metal–oxide–semiconductor field-effect transistor) demonstrated by Egyptian engineer Mohamed M. Atalla and Korean engineer Dawon Kahng at Bell Labs in 1960 was an enhancement-mode silicon semiconductor device. Alternatively, rather than static logic gates, dynamic logic such as four-phase logic was sometimes used in processes that did not have depletion-mode transistors available.įor example, the 1971 Intel 4004 used enhancement-load silicon-gate PMOS logic, and the 1976 Zilog Z80 used depletion-load silicon-gate NMOS. Logic families built in older processes that did not support depletion-mode transistors were retrospectively referred to as enhancement-load logic, or as saturated-load logic, since the enhancement-mode transistors were typically connected with gate to the V DD supply and operated in the saturation region (sometimes the gates are biased to a higher V GG voltage and operated in the linear region, for a better power–delay product (PDP), but the loads then take more area). Moving the gate voltage toward the drain voltage "enhances" the conduction in the channel, so this defines the enhancement mode of operation, while moving the gate away from the drain depletes the channel, so this defines depletion mode.Įnhancement-load and depletion-load logic families ĭepletion-load NMOS logic refers to the logic family that became dominant in silicon VLSI in the latter half of the 1970s the process supported both enhancement-mode and depletion-mode transistors, and typical logic circuits used enhancement-mode devices as pull-down switches and depletion-mode devices as loads, or pull-ups. Some sources say "depletion type" and "enhancement type" for the device types as described in this article as "depletion mode" and "enhancement mode", and apply the "mode" terms for which direction the gate–source voltage differs from zero. Such devices are used in gallium arsenide and germanium chips, where it is difficult to make an oxide insulator. Junction field-effect transistors ( JFETs) are depletion-mode, since the gate junction would forward bias if the gate were taken more than a little from source toward drain voltage. Key voltages (with +3 V or −3 V threshold voltage) The mode can be determined by the sign of the threshold voltage (gate voltage relative to source voltage at the point where an inversion layer just forms in the channel): for an N-type FET, enhancement-mode devices have positive thresholds, and depletion-mode devices have negative thresholds for a P-type FET, enhancement-mode have negative, and depletion-mode have positive. For N-type depletion-load devices, the threshold voltage might be about −3 V, so it could be turned off by pulling the gate 3 V negative (the drain, by comparison, is more positive than the source in NMOS). Such devices are used as load "resistors" in logic circuits (in depletion-load NMOS logic, for example). ![]() In a depletion-mode MOSFET, the device is normally on at zero gate–source voltage. In most circuits, this means pulling an enhancement-mode MOSFET's gate voltage towards its drain voltage turns it on. ![]() NMOS can be turned on by pulling the gate voltage higher than the source voltage, PMOS can be turned on by pulling the gate voltage lower than the source voltage. These devices are off at zero gate–source voltage. In field-effect transistors (FETs), depletion mode and enhancement mode are two major transistor types, corresponding to whether the transistor is in an on state or an off state at zero gate–source voltage.Įnhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common switching elements in most integrated circuits.
