Shared tech workspaces spread beyond sands of Silicon Beach

In a sign of increased desire of professionals to work remotely, the successful Santa Monica shared workspace Cross Campus is opening a second location in Pasadena later this month, and the company hopes to open eight others in Southern California and beyond in the next two years. 

Dubbed by one user as  the “nerve center” of the Silicon Beach tech scene, Cross Campus opened its membership-based workspace facility in Santa Monica in 2012.   

But co-founder Ronen Olshansky said the shared workspace phenomenon isn't limited to coders. 

"Fewer and fewer people are making the traditional drive into the corporate office," Olshansky said. "They're working remotely as professionals, going off on their own as freelancers, or they're starting their own companies as entrepreneurs."  

A forecast from Forrester Research says that 43 percent of workers will telecommute by 2016, compared to estimates of about a quarter of the workforce telecommuting last year. 

Olshansky said that, for many people, working from home or in a coffee shop isn't productive. 

That's led shared workspaces to pop up in Los Angeles, Culver City and Santa Monica. Among them: Maker City L.A., WeWork, NextSpace, Coloft and Hub LA.  

Los Angeles-based tech investor David Waxman said these kind of shared spaces are crucial for the early stages of tech ventures.

"When you’re just starting out, and capital is very scarce, having not to commit to an entire office but having part of an office is very important," Waxman said.  “There comes a collective energy when a bunch of entrepreneurs get together in the same space, even if they’re not working on the same project."

And he said Pasadena is a good choice for a shared workspace.

"It is the home of Caltech, the Arts Center, and IdeaLab — probably the world’s first tech incubator — started there," he said.

But he said the need isn't limited to Pasadena.

"In Silver Lake, in South Pasadena, in Glendale, you see a lot of little pockets of  people getting together, and as soon as there’s a critical mass, we’ll see co-working spaces like Cross Campus come into being," said Waxman, who named his investment firm TenOneTen after the two freeways that connect Santa Monica and the Westside to Pasadena. 

Alex Maleki of IdeaLab in Pasadena is happy a well-known company is opening up in his city. 

"Anything that helps attract talent and capital to the region," Maleki said, "is absolutely fantastic."

A thermal deformation optimization method for cryogenically cooled silicon crystal monochromators under high heat load

A method to optimize the thermal deformation of an indirectly cryo-cooled silicon crystal monochromator exposed to intense X-rays at a low-emittance diffraction-limited synchrotron radiation source is presented. The thermal-induced slope error of the monochromator crystal has been studied as a function of heat transfer efficiency, crystal temperature distribution and beam footprint size. A partial cooling method is proposed, which flattens the crystal surface profile within the beam footprint by modifying the cooling contact area to optimize the crystal peak temperature. The optimal temperature varies with different photon energies, which is investigated, and a proper cooling strategy is obtained to fulfil the thermal distortion requirements over the entire photon energy range. At an absorbed power up to 300 W with a maximum power density of 44.8 W mm−2 normal incidence beam from an in-vacuum undulator, the crystal thermal distortion does not exceed 0.3 µrad at 8.33 keV. This method will provide references for the monochromator design on diffraction-limited synchrotron radiation or free-electron laser light sources.

Characterization of silicon pore optics for the NewAthena X-ray observatory in the PTB laboratory at BESSY II

The New Advanced Telescope for High ENergy Astrophysics (NewAthena) will be the largest space-based X-ray observatory ever built. It will have an effective area above 1.1 m2 at 1 keV, which corresponds to a polished mirror surface of about 300 m2 due to the grazing incidence. As such a mirror area is not achievable with an acceptable mass even with nested shells, silicon pore optics (SPO) technology will be utilized. In the PTB laboratory at BESSY II, two dedicated beamlines are in use for their characterization with monochromatic radiation at 1 keV and a low divergence well below 2 arcsec: the X-ray Pencil Beam Facility (XPBF 1) and the X-ray Parallel Beam Facility (XPBF 2.0), where beam sizes up to 8 mm × 8 mm are available while maintaining low beam divergence. This beamline is used for characterizing mirror stacks and controlling the focusing properties of mirror modules (MMs) – consisting of four mirror stacks – during their assembly at the beamline. A movable CCD based camera system 12 m from the MM registers the direct and the reflected beams. The positioning of the detector is verified by a laser tracker. The energy-dependent reflectance in double reflection through the pores of an MM with an Ir coating was measured at the PTB four-crystal monochromator beamline in the photon energy range 1.75 keV to 10 keV, revealing the effects of the Ir M edges. The measured reflectance properties are in agreement with the design values to achieve the envisaged effective area.

The diamond–silicon carbide composite Skeleton® as a promising material for substrates of intense X-ray beam optics

The paper considers the possibility of using the diamond-silicon carbide composite Skeleton® with a technological coating of polycrystalline silicon as a substrate for X-ray mirrors used with powerful synchrotron radiation sources (third+ and fourth generation). Samples were studied after polishing to provide the following surface parameters: root-mean-square flatness ≃ 50 nm, micro-roughness on the frame 2 µm × 2 µm σ ≃ 0.15 nm. The heat capacity, thermal conductivity and coefficient of linear thermal expansion were investigated. For comparison, a monocrystalline silicon sample was studied under the same conditions using the same methods. The value of the coefficient of linear thermal expansion turned out to be higher than that of monocrystalline silicon and amounted to 4.3 × 10−6 K−1, and the values of thermal conductivity (5.0 W cm−1 K−1) and heat capacity (1.2 J K−1 g−1) also exceeded the values for Si. Thermally induced deformations of both Skeleton® and monocrystalline silicon samples under irradiation with a CO2 laser beam have also been experimentally studied. Taking into account the obtained thermophysical constants, the calculation of thermally induced deformation under irradiation with hard (20 keV) X-rays showed almost three times less deformation of the Skeleton® sample than of the monocrystalline silicon sample.

Comparing single-shot damage thresholds of boron carbide and silicon at the European XFEL

Xray free-electron lasers (XFELs) enable experiments that would have been impractical or impossible at conventional X-ray laser facilities. Indeed, more XFEL facilities are being built and planned, with their aim to deliver larger pulse energies and higher peak brilliance. While seeking to increase the pulse power, it is quintessential to consider the maximum pulse fluence that a grazing-incidence FEL mirror can withstand. To address this issue, several studies were conducted on grazing-incidence damage by soft X-ray FEL pulses at the European XFEL facility. Boron carbide (B4C) coatings on polished silicon substrate were investigated using 1 keV photon energy, similar to the X-ray mirrors currently installed at the soft X-ray beamlines (SASE3). The purpose of this study is to compare the damage threshold of B4C and Si to determine the advantages, tolerance and limits of using B4C coatings.

{N-[1-(2-Oxidophen­yl)ethyl­idene]-dl-alaninato}(pentane-1,5-di­yl)silicon(IV)

The title SiIV complex, C16H21NO3Si, is built up by a tridentate dinegative Schiff base ligand bound to a sila­cyclo­hexane unit. The coordination geometry of the penta­coordinated SiIV atom is a distorted trigonal bipyramid. The presence of the sila­cyclo­hexane ring in the complex leads to an unusual coordination geometry of the SiIV atom with the N atom from the Schiff base ligand and an alkyl-C atom in apical positions of the trigonal bipyramid. There is a disorder of the methyl group at the imine bond with two orientations resolved for the H atoms [major orientation = 0.55 (3)]. In the crystal, C—H⋯O inter­actions are found within corrugated layers of mol­ecules parallel to the ab plane.

Synthesis and crystal structures of bis­[1-oxopyridin-2-olato(1−)]bis­(penta­fluoro­phen­yl)silicon(IV)–tetra­hydro­furan–pentane (2/1/1), bis­[1-oxopyridin-2-olato(1−)]bis­(p-tol­yl)silicon(IV), and dimes

The neutral organosilicon(IV) complex, (C6F5)2Si(OPO)2 (OPO = 1-oxopyridin-2-one, C5H4NO2), was synthesized from (C6F5)2Si(OCH3)2 and 2 equiv. of 1-hy­droxy­pyridin-2-one in tetra­hydro­furan (THF). Single crystals grown from the diffusion of n-pentane into a THF solution were identified as a THF hemisolvate and an n-pentane hemisolvate, (C6F5)2Si(OPO)2·0.5THF·0.5C5H12 (1). p-Tol­yl2Si(OPO)2 (2) and mesit­yl2Si(OPO)2 (3) crystallized directly from reaction mixtures of 2 equiv. of Me3Si(OPO) with p-tol­yl2SiCl2 and mesit­yl2SiCl2, respectively, in aceto­nitrile. The oxygen-bonded carbon and nitro­gen atoms of the OPO ligands in 1, 2, and 3 were modeled as disordered indicating co-crystallization of up to three possible diastereomers in each. Solution NMR studies support the presence of exclusively the all-cis isomer in 1 and multiple isomers in 2. Poor solubility of 3 limited its characterization in solution.

Development of hard X-ray photoelectron spectroscopy in liquid cells using optimized microfabricated silicon nitride membranes

We present first hard X-ray photoelectron spectroscopy (HAXPES) results of aqueous salt solutions and dispersions of gold nanoparticles in liquid cells equipped with specially designed microfabricated thin silicon nitride membranes, with thickness in the 15–25 nm range, mounted in a high-vacuum-compatible environment. The experiments have been performed at the HAXPES endstation of the GALAXIES beamline at the SOLEIL synchrotron radiation facility. The low-stress membranes are fabricated from 100 mm silicon wafers using standard lithography techniques. Platinum alignment marks are added to the chips hosting the membranes to facilitate the positioning of the X-ray beam on the membrane by detecting the corresponding photoemission lines. Two types of liquid cells have been used, a static one built on an Omicron-type sample holder with the liquid confined in the cell container, and a circulating liquid cell, in which the liquid can flow in order to mitigate the effects due to beam damage. We demonstrate that the membranes are mechanically robust and able to withstand 1 bar pressure difference between the liquid inside the cell and vacuum, and the intense synchrotron radiation beam during data acquisition. This opens up new opportunities for spectroscopic studies of liquids.

How Silicon Valley Bank failed

Silicon Valley Bank was the 16th largest bank in America, the bank of choice for tech startups and big-name venture capitalists. Then, in the span of just a few days, it collapsed. Whispers that SVB might be in trouble spread like wildfire through group texts and Twitter posts. Depositors raced to empty their accounts, withdrawing $42 billion in a single day. Last Friday, after regulators declared that SVB had failed, the FDIC seized the bank.

As the dust settles on the biggest bank failure — and bank rescue — in recent memory, we're still figuring out what happened. But poor investment choices, weak regulation, and customer panic all played their parts. We'll look into the bank's collapse to understand what it can teach us about the business of banking itself.

Glenn Greenwald says that the Democratic Party, NSA, CIA, Neocons, Silicon Valley, Wall Street, mainstream media have united to impose an authoritarian government of censorship and suppression of information

The CIA from the very first days of the Trump administration, even before he was inaugurated, devoted themselves to sabotaging the administration because Donald Trump questioned just a few of their pieties. And that can't be done in Washington. Whoever does that must be destroyed. And so the CIA and the Deep State operatives became heroes of the liberal left, the people who support the Democratic party. They're now in a full union with the neocons, the Bush Cheney operatives, the CIA, Silicon Valley, and Wall Street. That is the union of power along with mainstream media outlets that are fully behind the Democratic party, which is likely to at least take over one branch of government, if not all of them, with the coming election, and that is a very alarming proposition because they're authoritarian, they believe in censorship, and they believe in suppression of information that exposes them in any kind of a critical light.
