Only those Indian nationals who show no signs of contracting the coronavirus infection and have been stranded in the US due to the lockdown are allowed to board the first repatriation flight of Air India from San Francisco to Mumbai and Hyderabad on Saturday. Over 10,000 registrations were recieved. People travelling under compelling circumstances were prioritised.

As the government came under attack from the Opposition during the debate on the recent communal riots in the national capital that have claimed over 50 lives, the BJP members alleged that the violence was a pre-planned conspiracy and the home minister and authorities took pro-active steps to control the situation.

As an industry, we’ve worked to established many new practices and tools for nimble design teams, from A/B testing to measuring bounce rates and CTR performance. But a lot of these methods require engineers or some amount of technical know-how to execute, and they take place only after something has been launched.

The judicious application of “dumb data” can streamline your workflow and improve your designs

What many people don’t know is that there are some unexpected applications of data to consider earlier in the design process, which you, the designer, can do yourself. They’re not fancy, and you don’t need to know how to write SQL queries. The judicious application of just-enough “dumb data” can streamline your workflow and improve your designs in surprisingly useful ways.

The structures are described of two bis-chelated metal complexes of nickel(II) and copper(II) with S-n-hexyl 3-(1-phenyl­ethyl­idene)di­thio­carbazate Schiff bases in a cis configuration, namely, bis­[S-n-hexyl 3-(1-phenyl­ethyl­idene)di­thio­carbazato-κ2N3,S]nickel(II), [Ni(C15H21N2S2)2], and bis­[S-n-hexyl 3-(1-phenyl­ethyl­idene)di­thio­carbazato-κ2N3,S]copper(II), [Cu(C15H21N2S2)2]. In both complexes, the metals have distorted square-planar geometries. A search in the Cambridge Structural Database [Groom et al. (2016). Acta Cryst. B72, 171–179] for bis-chelated nickel(II) and copper(II) complexes with similar Schiff bases retrieved 55 and 36 hits for the two metals, respectively. An analysis of the geometrical parameters of complexes showing cis and trans configurations is reported and the values compared with those for the complexes described in this work.

The title compound, [Mn(C3H7NO)4(H2O)2][Cu5(C7H4NO3)4]·C3H7NO or cis-[Mn(H2O)2(DMF)4]{Cu[12-MCCu(II)N(shi)-4]}·DMF, where MC is metallacrown, shi3− is salicyl­hydroximate, and DMF is N,N-di­methyl­formamide, crystallizes in the monoclinic space group P21/n. Two crystallographically independent metallacrown anions are present in the structure, and both anions exhibit minor main mol­ecule disorder by an approximate (non-crystallographic) 180° rotation with occupancy ratios of 0.9010 (9) to 0.0990 (9) for one anion and 0.9497 (8) to 0.0503 (8) for the other. Each penta­copper(II) metallacrown contains four CuII ions in the MC ring and a CuII ion captured in the central cavity. Each CuII ion is four-coordinate with a square-planar geometry. The anionic {Cu[12-MCCu(II)N(shi)-4]}2− is charged-balanced by the presence of a cis-[Mn(H2O)2(DMF)4]2+ cation located in the lattice. In addition, the octa­hedral MnII counter-cation is hydrogen bonded to both MC anions via the coordinated water mol­ecules of the MnII ion. The water mol­ecules form hydrogen bonds with the phenolate and carbonyl oxygen atoms of the shi3− ligands of the MCs.

This article describes a high-efficiency experimental configuration for a self-referenced lattice comparator with a `brush beam' of synchrotron radiation from a bending magnet and two linear position-sensitive photon-counting-type X-ray detectors. The efficiency is more than ten times greater compared with the `pencil-beam' configuration and a pair of zero-dimensional detectors. A solution for correcting the systematic deviation of d-spacing measurements caused by the horizontal non-uniformity of the brush beam is provided. Also, the use of photon-counting-type one-dimensional detectors not only improves the spatial resolution of the measurements remarkably but can also adjust the sample's attitude angles easily.

Yesterday, we heard about the hyper-loop, a system that could get you from L.A. to San Francisco in about 30 minutes without losing your eyeballs.

Steve Julian: Business analyst Mark Lacter, that might come in handy given how crowded California's air corridor has become...

Mark Lacter: We'll talk about the hyper-loop in a moment, Steve, but yes, the L.A.-to-San Francisco air route is the busiest in the U.S., and it's already the most competitive.  We're talking about more than 50 flights a day, which - if you spread them out between six in the morning and 10:30 at night - there'd be one flight every 20 minutes.  But, Delta obviously thinks there's room for more because it's announced an hourly shuttle between the two cities.  That's another 14 daily flights beginning September 3.  The airline will be using a somewhat smaller jet, and it sounds as if the focus will be on the business traveler, with free newspapers, wine, and beer.

Julian: How much will it cost, do we know?

Lacter: As usual, it's a lot cheaper if you make an advance purchase, but if you're buying your tickets at the last minute - which is what a lot of business travelers do - roundtrip runs a hefty $430.  Actually, this Bay Area shuttle is just the latest effort by Delta to expand out of LAX, which is different from other major airports in that it doesn't have any one airline that dominates (United has a slight edge in market share over American, with Delta about three percentage points behind).  American also has been adding flights out of LAX.

Julian: Sounds like the airline business is improving...

Lacter: That's what happens when you pack planes to the absolute max, which is bad news for travelers being crammed into coach seats.  But it's good news for LAX, which continues to be the airport of choice among airlines looking to add service - matter of fact, domestic passenger traffic was up almost 8 percent in June compared with a year earlier.  Some of those gains might be at the expense of service elsewhere - most especially Ontario Airport, which has seen a big exodus among airlines and passengers.  Ontario city officials have been trying to regain control of the airport, which has been operated by the city of Los Angeles.

Julian: Back to the hyper-loop - is this kind of transport possible?

Lacter: Well, it's the brainchild of billionaire Elon Musk, and you never say never with this guy.  He started the electric car company Tesla and the private space company Space X.  The hyper-loop is a high-speed system of passenger pods that would travel on a cushion of air (think of air hockey table).  The pods would travel at more than 700 miles per hour, but they wouldn't result in sonic booms that severely restricted the Concorde aircraft.  Of course, anything that promises super-speed travel is bound to get people talking - and, from what the physics professors are saying, the Musk idea seems feasible.

Julian: How would its cost compare to the bullet train?

Lacter: He says a lot cheaper.  The price tag on the train is $70 billion at last check; Musk says he can do his for $6 billion.  But, the issue isn't so much the cost or even the technology, but the politics.  As a rule, governments do not think outside the box, and that's what a project like this is all about.  Already, you have bullet train supporters saying that the hyper-loop is impossible, but what they're really saying is we have a lot riding on the train, and we don't want this guy to mess it up.

Julian: But, how much demand is there for high-speed transport?

Lacter: You'd think there would be a lot, but when Boeing came up with a nifty idea for a souped-up plane that would shave almost an hour from L.A. to New York, the airlines said no because it would require more fuel - and that would mean raising fares.  Musk says his system would be a lot cheaper than traveling by plane, which could be a game changer in the attitudes about going places.  But, those attitudes won't change until the thing is actually built, and that can't realistically happen until attitudes change.  That's the ultimate problem.

Julian: Hence, why we're content to squeeze into coach.

Lacter: Yep.

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).
