This work presents a technique for extracting the detailed shape of peaks with extended, overlapping tails in an X-ray powder diffraction pattern. The application discussed here concerns crystallite size broadening, though the technique can be applied to spectra of any origin and without regard to how the profiles are to be subsequently analyzed. Historically, the extraction of profile shapes has been difficult due to the complexity of determining the background under the peak, resulting in an offset of the low-frequency components of the Fourier transform of the peak known as the `hook' problem. The use of a carefully considered statistical weighting function in a non-linear least-squares fit, followed by summing the residuals from such a fit with the fit itself, allows one to extract the full shape of an isolated peak, without contributions from either the background or adjacent peaks. The extracted shape, consisting of the fit function recombined with the residuals, is not dependent on any specific shape model. The application of this to analysis of microstructure is performed independently of global parametric models, which would reduce the number of refined parameters; therefore the technique requires high-quality data to produce results of interest. The effectiveness of the technique is demonstrated by extraction of Fourier transforms of peaks from two sets of size-broadened materials with two differing pieces of equipment.

Experimental electron-density studies based on high-resolution diffraction experiments allow halogen bonds between heavy halogens to be classified. The topological properties of the electron density in Cl⋯Cl contacts vary smoothly as a function of the inter­action distance. The situation is less straightforward for halogen bonds between iodine and small electronegative nucleophiles, such as nitro­gen or oxygen, where the electron density in the bond critical point does not simply increase for shorter distances. The number of successful charge–density studies involving iodine is small, but at least individual examples for three cases have been observed. (a) Very short halogen bonds between electron-rich nucleophiles and heavy halogen atoms resemble three-centre–four-electron bonds, with a rather symmetric heavy halogen and without an appreciable σ hole. (b) For a narrow inter­mediate range of halogen bonds, the asymmetric electronic situation for the heavy halogen with a pronounced σ hole leads to rather low electron density in the (3,−1) critical point of the halogen bond; the properties of this bond critical point cannot fully describe the nature of the associated inter­action. (c) For longer and presumably weaker contacts, the electron density in the halogen bond critical point is only to a minor extent reduced by the presence of the σ hole and hence may be higher than in the aforementioned case. In addition to the electron density and its derived properties, the halogen–carbon bond distance opposite to the σ hole and the Raman frequency for the associated vibration emerge as alternative criteria to gauge the halogen-bond strength. We find exceptionally long C—I distances for tetra­fluoro­diiodo­benzene molecules in cocrystals with short halogen bonds and a significant red shift for their Raman vibrations.

An efficient synthesis of 1-aryl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazo­tization of 3-amino-4-aryl­amino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The mol­ecules of 1-phenyl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C—H⋯N and C—H⋯O hydrogen bonds, while the structures of 1-(2-methyl­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the mol­ecules into simple chains, which are further linked into sheets by π-stacking inter­actions in (II) but not in (III). In the structure of 1-(4-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the mol­ecules into sheets. When com­pound (II) was exposed to a strong acid in methanol, qu­anti­tative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hy­droxy-1-(2-methyl­phen­yl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the mol­ecules are linked by paired O—H⋯O hydrogen bonds to form centrosymmetric dimers.

There have been plenty of video game movies over the years, but there have been far fewer actually good ones. "Ready Player One," based on the 2011 video game-inspired novel, has the chance to be a great one thanks to the announcement that Steven Spielberg has signed on to direct.

That book was inspired by classic video games, and was written using classic video game cheats to play parts of classic games and write them into his book, author Ernest Cline said in a recent talk. That got us thinking about the classic video game cheats and secrets that stuck with us from our younger days playing classic video games — here's our top 11.

1. The Konami Code

Up up down down left right left right B A start! This code became such a part of video game culture that it got its own name. It was popularized in various games made by Konami, particularly Contra, leading to it also being known as the "Contra Code" for its ability to give you 30 lives in the game. Before the Internet, it was spread through gaming magazines and word of mouth — it was so influential that there are still developers who put it in their games. (There's even an entire Wikipedia page of games, both from Konami and others, that use the Konami Code. It's even been used on some websites.)

What is the Konami Code

2. Street Figher II Turbo's turbo

The game that I actually used a code for the most as a kid, the Super Nintendo code down, R, up, L, Y, B on the second controller didn't give you any advantages — it just kicked the speed up. By default, you had a few selections for how fast the game would be, but you could multiple that several-fold with this code, letting you and your friends battle at what at the time felt unbelievably fast.

3. Super Mario Bros.'s Minus World

This one doesn't involve a code, but players managed to discover what was deemed a glitch in the game that put you into a messed up version of another level, dubbed by fans the Minus World due to just "-1" instead of a full level number appearing at the top of the screen. There was no way to escape the glitched level, no matter how hard you might try, sending you to play it over and over again until your time ran out or you were killed by enemies. Still, modern players have found that you can go on thanks to various computer emulators and the like; see some of the worlds beyond below:

Minus World video

4. Metroid and Justin Bailey

Fans early on discovered that the password JUSTIN BAILEY allowed you to start with all of the available weapons along with plenty of life and ammo. Fans didn't know whether Justin Bailey was a reference to an actual person, just a code coincidence or something else, but that didn't stop them from eagerly playing through with this code. It also removed lead character Samus Aran from her armor, allowing players to discover that the game's star was an early female lead character, even if her armor didn't clue players in before the end of the game without the code.

5. Doom's God mode

By typing the letters iddqd in PC game Doom, players could enable God mode, making them essentially invincible and letting them power through the early first-person shooter. The code had been available in developer id's earlier game Wolfenstein, but hadn't been quite as easily accessible. So, if you ever need a power boost when you're fighting on Mars, Doom has the answer. (Unfortunately, we don't believe this provides any extra protection for NASA's Mars rovers.)

6. Mortal Kombat's Reptile

The developers of Mortal Kombat made a battle against Reptile unbelievably hard for Mortal Kombat fans, including putting some randomness into whether doing what you were supposed to do to unlock the character would even work. Still, players happily pumped in extra quarters for the chance to face off against Reptile, a character with a look that mirrored that of characters Sub-Zero and Scorpion, just with a different color. Players had to achieve a Double Flawless victory on the Pit level, finish the match using their fatality move, and there also had to be a silhouette flying past the moon in the background — which only happened every sixth game.

Mortal Kombat: Reptile

7. The Legend of Zelda's Second Quest

The Legend of Zelda was a pretty challenging early adventure game, one of the first releases for the Nintendo home video game console. When you beat the game, you were given the option to go on a "Second Quest," which was a tweaked version of the game you just played except waaaaay harder. However, if you thought you were the coolest kid on the block and were so awesome you didn't need a warmup, you could name your character "ZELDA" (in one of the more obvious cheats in video game history) and skip ahead to that Second Quest from the start. You would then likely cry from how hard it was and start another new game with a different name.

8. NBA Jam's celebrity secret characters

A variety of celebrities from sports, music, and even politics were available by putting in various initials combined with buttons on the controller. These included then-President Bill Clinton, Al Gore, Warren Moon and more. That tradition has been continued in more recent NBA Jam games, with President Obama and others available for your video gaming pleasure.

9. GoldenEye's extra modes

There were a wide variety of cheat codes for GoldenEye, widely considered one of the all-time great first-person shooters. Sure, you could use codes to unlock different levels, but the reason these codes are remembered is because it gave you all sorts of new ways to play against your friends. The game also had an actual cheat menu that would appear if you accomplished one of a variety of goals, and from that menu you could cheat extra hard by using your controller to unlock things like a paintball mode, turbo mode, modes with both giant heads and teeny-tiny James Bonds and more.

10. Sonic The Hedgehog 2's Debug Mode

The Sonic debug mode is the perfect example of why so many games included cheats back in the day: They were often for the developers to be able to more easily play the games while looking for bugs and doing other testing. Sonic 2 let you get to an actual debug mode by playing various sounds from the level select screen (1, 9, 9, 2, 1, 1, 2, 4, for your reference), then pressing start and holding the A button. Developers later put them in for fun and intended them for the players to discover, but some of the early cheat codes were just meant for developers — but players proved more intrepid than they may have anticipated.

Sonic debug mode

11. Mike Tyson's Punch-Out: Go straight to Mike Tyson

There was actually a password mode in this game — before games had the option to save, plenty of games gave you codes that let you get back to where you were before. This is one of the examples from that darker time, where whether you played through opponents like Glass Joe and Bald Bull or not, you could try your changes against Lightning Mike (at least until the video game's license ran out and he was replaced in future editions with the way less exciting "Mr. Dream"). You better have had a pen and paper ready when your friend started yelling at you 007 373 5963 for you to use on your own copy of the game — no sharing. The game is hard enough that even Mike Tyson had some trouble fighting himself:

Let us know in the comments the classic video games — and the classic cheat codes and secrets — that inspired you.

Los Angeles Unified School District officials have cleared the way for principals to tap into a major source of funding for arts programs targeting low-income students starting this fall.

Although state and federal officials previously said national Title I dollars, allocated to help disadvantaged students improve in academics, could be used for the arts instruction, some district officials had been reluctant to move ahead. The latest decision reverses the district's long-standing practice and opens the door for Title I-funded arts instruction that helps students improve their academic performance. 

"This has been a long time coming and this really is a day of rejoicing, quite frankly, in LAUSD," said Rory Pullens, the district's executive director of arts education. 

RELATED: For Pasadena school, arts plus math is really adding up

A two-page memo issued Thursday from Pullens, Deputy Superintendent Ruth Perez and Karen Ryback, executive director of Federal and State Education Programs, confirms the arts as a core subject and allows schools with high percentages of low-income students to use Title I funds for the arts.

Those schools "may utilize arts as an integration strategy to improve academic achievement," the directive reads. However, Title I funds are not allowed "to fund programs whose primary objective is arts education," according to the memo. As an example, the funds could be tapped to help students learn a character's point of view in a lesson that requires acting out a skit. 

Title I funding, developed in 1965 as part of President Lyndon Johnson's war on poverty, has been used historically to increase students success in reading and math. The funds have paid for efforts like reading coaches or math tutors, supplemental software programs and professional development for teachers to improve low-performing students' test scores.

At $14 billion a year, the Title I funds make up the federal government's largest expenditure for grades K-12. The majority of LAUSD schools receive Title I dollars.

Arts advocates have long sought to get the second-largest district in the country to shift its stance on Title I arts funding, arguing that the arts have been shown in research to boost student academic performance. 

LAUSD joins just a handful of districts around the state that have committed to a district-wide Title I plan including the arts. San Diego Unified, Sacramento City Unified and Chula Vista Elementary School District are among them, according to Joe Landon, executive director of the California Alliance for Arts Education. 

Landon says beyond these districts, the decision to use Title I for the arts is largely playing out on a school-by-school basis. Some principals are using Title I funds for the arts, but they're doing so largely under the radar, some fearing that state monitors will say the funds were used incorrectly. 

"At each level, there are people that are afraid," Landon said. The reason: schools are accountable for how Title I dollars are spent and misuse could cause schools to lose a valuable funding source. Despite the state and federal directives on Title I allowing arts instruction in academics, school officials have been hesitant to make changes because Title I spending is monitored so closely. 

Landon explained that a decision to use Title I funds for the arts is momentous for schools.

"When districts begin to move," he said, "that really changes it."

Attention turns to principals, funding gatekeepers

When Los Angeles Unified brought on Pullens, attracting him from a well-known arts school in Washington, D.C., he took on the task of securing Title I funding in his early months on the job. He said budgeting would be a huge challenge in increasing access to the arts for more of the district's students. 

The deed now done, Pullens said: "This was clearly a very high priority of what we wanted to accomplish and we are just so thrilled that this has finally come to pass."

It'll now be up to school principals to decide how much of their Title I funding to allocate for arts instruction. Pullens said plans to train principals on the benefits of arts integration are underway.

While the Title I arts spending is not mandatory, he expects the new directive to free up significant funding for the district's arts efforts. He didn't have exact estimates, but pointed out that schools' Title I funds range anywhere from hundreds of dollars to hundreds of thousands of dollars per school. 

As KPCC reported in July, only about 70 of the district's more than 500 elementary schools were on track to provide all four art forms (dance, visual arts, music and theater) for the 2014-2015 school year — a legal requirement under the California education code. 

Cheryl Sattler, senior partner with the Florida-based consulting firm Ethica, has worked closely with about 100 school districts nationwide and estimates only two have used Title I funding for the arts.

“The urgency is to try to get kids to read," she said, "and if you have kids, for example, in the 10th grade who are reading at a 3rd or 4th-grade level, it’s really hard to think past that, because that’s the emergency.” The arts are often left out of the conversation, according to Sattler, which means they're left out of funding.

“I think the issue is that largely principals, and school improvement committees, and other folks who are worried about academic performance don’t always look to the arts and they don’t always know the research about how powerful arts can be,” she said. 

The LAUSD directive described examples of arts integration activities that schools might consider:

• Invite community members to demonstrate or share their talents with students as a prompt for a writing assignment.
• Have students create models that display mathematical data pertaining to each planet of the solar system: distance from the sun, length of day and night, length of year, and day and night surface temperatures.
• Ask students to create a small piece of dance/movement that models their understanding of geometric concepts.
• Encourage students to explore the science of sound by utilizing rubber bands, oatmeal containers, coffee cans, balloons, etc. to construct one or more of the four families of musical instruments: strings, woodwinds, brass and percussion.
• Have students write and perform a short skit to illustrate a literary character’s point of view.
• Provide a lesson on utilizing a software program to create an animated film that highlights key historical events that occurred during the Civil War (In this instance, the cost of the software program would be an appropriate Title I expenditure).

Needle pricks not your thing? A team of National Science Foundation-funded scientists is developing wearable skin sensors that can detect what's in your sweat. They hope that one day, monitoring perspiration could bypass the need for more invasive procedures like blood draws, and provide real-time updates on health problems such as dehydration or fatigue. In a new paper, the team describes a new sensor design that can be rapidly manufactured using a "roll-to-roll" processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. They used the sensors to monitor the sweat rate, and the electrolytes and metabolites in sweat, from volunteers who were exercising, and others who were experiencing chemically induced perspiration. The new sensors contain a spiraling microscopic tube, or microfluidic, that wicks sweat from the skin. By tracking how fast the sweat moves through the microfluidic, the sensors can report how much a person is sweating, or their sweat rate. The microfluidics are also outfitted with chemical sensors that can detect concentrations of electrolytes like potassium and sodium, and metabolites like glucose.

For the last several summer drill seasons, most of Aben Resources Ltd.'s (ABN:TSX.V; ABNAF:OTCQB) attention has centered on its 23,000-hectare Forrest Kerr Gold Project, located in northern British Columbia, in the heart of the Golden Triangle.

Some of Canada's greatest mines, such as Premier, Snip and Eskay Creek, have been found on the Golden Triangle, located just inland from the Alaska Panhandle. Other significant and well-known deposits located within the Triangle include Brucejack, Galore Creek, Copper Canyon, Schaft Creek, KSM, Granduc and Red Chris.

In recent years, the Golden Triangle area has attracted lots of new exploration as infrastructure improvements, such as roads and power lines, have made access easier.

Aben's drills at Forrest Kerr at the end of the 2017 season discovered the North Boundary Zone, where values as high as 21.5 g/t gold, 28.5 g/t silver and 3.1% copper over 6 meters were unearthed. The following year drilling uncovered multiple high-grade gold zones at shallow depths in the zone, including an interval of 62.4 g/t Au over 6.0m starting at 114 meters downhole, establishing the continuity of the North Boundary Zone. Drilling also found the South Boundary Zone, located 1.5 kilometers from the North Boundary Zone, where assays showed "broad horizons of low-grade gold mineralization punctuated by intermittent intercepts of moderate to high-grade gold-silver-copper-zinc values."

For the 2019 exploration season, in nearly 10,000 meters of drilling that wrapped up on October-November 2019, Aben focused on the area south of the North Boundary Zone. "We were trying to find, not just continuity, but a structural source to it. We were drilling and testing a lot of these anomalies that showed up in the mag survey that we did at the beginning of last year before the season started. That was giving us good targets to work with," Aben CEO Jim Pettit told Streetwise Reports.

"As we headed south, much like the South Boundary Zone that we drilled back in 2018, we came up with these good intersections of gold and silver, but there were also lead-zinc and broader intersections of lower grade. So we had obviously come out of that zone that was high grade into a different type of mineralization," Pettit explained.

Pettit is hopeful that Aben will be able to explore Forrest Kerr this year. "Mining is deemed an essential activity in British Columbia, but, because of the coronavirus, we are concerned about the safety of our workers. We will be discussing this with the Tahltan Central Government to develop the proper protocols and make sure that the safeguards are in place for safely operating a camp."

The company has spent the winter analyzing its data in preparation for exploration this year. "We've gone through and detailed meter by meter all the drilling we've done. We've got some pretty good looking concepts to work with where we could be looking for possibly the feeder zone for the high-grade system and continuity," Pettit stated.

"Because of what we did last year on the west side of the Creek Fault, we've encountered another fault system that seems to be controlling a lot of the lower-grade mineralization as we headed south.," Pettit said. "If we follow that back up north toward the high-grade North Boundary Zone, there is a very large blind anomaly there that was not tested because it was covered in scree. This could give us some tremendous targets to work with.” "

In November, Aben reported that its drilling satisfied the expenditure requirements set out in the 2016 option agreement on the Forrest claim block, resulting in the company's 100% ownership of the Forrest Kerr property.

In addition to exploring Forrest Kerr, "Aben is always on the lookout for new projects to extend its exploration potential throughout the year," Pettit said.
