2 Earlier this month, the company said it’ll prompt European users of its Android operating system to choose their own search engine from 2020, after the European Commission’s determination last year that Google could be hampering consumer choice by demanding that its own apps and services must be the preinstalled, default options on Android phones. This saw Google getting slapped with a record 4.34 billion euro ($5 billion) antitrust fine, which it’s appealing.In the US, the Department of Justice last month said it’s opening an antitrust probe into tech giants, including Google parent company Alphabet, to examine their market power.First published at 4:11 a.m. PT.Updated at 6:45 a.m. PT: Adds EC confirmation about the letter. 1:49 Share your voice Google wants to make your job search easier Internet Services Google noted in its own emailed statement that it’s “worked with jobs providers” to improve its search function.”Any provider — from individual employers to job listing platforms — can use this feature in search, and many of them have seen a significant increase in the number of job applications they receive. Since launch, we’ve made a number of changes to address feedback in Europe,” a Google spokesperson wrote.”These changes include testing a new choice carousel at the top of the unit, which links directly to job sites, and linking directly to job offers when they only exist on a single site. Job seekers can decide which result or experience is most relevant for them.” Google’s 2-year-old job search service drew an antitrust complaint in the EU. Budrul Chukrut/SOPA Images/LightRocket via Getty Images Google faces another antitrust allegation in the European Union — this time focused on its job search service. A group of 23 job search websites sent a letter to EU competition commissioner Margrethe Vestager saying the search giant abused its dominant position at their expense, according to Reuters.The company launched the service in 2017, and later amped it up by adding information on salary and the ability to search for jobs by location.The rival companies alleged that Google’s putting a large widget for its service at the top of people’s job searches is unfair because it doesn’t have to spend any money marketing the service, while traditional job search companies do. They asked Vestager to temporarily order Google to stop doing this while she looks into its practices, Reuters reported.”We confirm we have received the letter and we will assess it,” a European Commission spokesperson wrote an emailed statement.

ARA San Juan submarine in Buenos Aires. The Argentine submarine is still missing in Argentine waters after it lost communication more than 48 hours ago. AFP file photoArgentina’s navy was hunting Friday for one of its submarines, which has been reported missing in the South Atlantic with a crew of 44 on board.The navy said it had not had any contact with the submarine, the San Juan, for 48 hours.“We have not been able to find, or have visual or radar communication with the submarine,” navy spokesman Enrique Balbi told a news conference.The United States, Britain and Chile had offered “logistical support and information exchange in this humanitarian search,” the foreign ministry in Buenos Aires said.The TR-1700 class diesel electric submarine had been returning from a routine mission to Ushuaia near the southernmost tip of South America, to its base at Mar del Plata, around 400 kilometers (240 miles) south of Buenos Aires.The San Juan’s last contact with the navy command was on Wednesday morning, Balbi said.Argentina said it had launched an air and sea search on Thursday, involving a destroyer and two corvettes.An initial search in an area around the sub’s last known position, some 430 kilometers off the southeastern Valdez peninsula, provided no clues.Balbi said an initial search was hampered “because it was carried out at night and in bad meteorological conditions prevailing in the area of operations.”The three navy ships and two aircraft flying rotations had “already swept 15 percent of the search area,” Balbi told reporters.The vessel had not activated its emergency beacon, he said.The navy denied a press report that there may have been a fire onboard.Balbi appealed for caution.“I don’t want to dramatize the issue. We’re lacking communication and don’t know what happened,” he said.“There may be a battery issue, a problem of power supply,” the spokesman said, adding that navy protocol was that the submarine would surface if any power problems were detected.The San Juan sailed 10 days ago from Mar del Plata to Ushuaia. It spent three days there before heading back to base, Balbi said.Among those on board is Argentina’s first female submarine officer, 35-year-old weapons officer Eliana Krawczyk.“Let us pray that nothing has happened to any crew member. At sea they are all brothers, and a submarine carries more risk than a ship,” her father Eduardo told Todo Noticias TV.The San Juan is one of three submarines in the Argentine fleet.Sixty-five meters (213 feet) long and seven meters wide, it was built by Germany’s Thyssen Nordseewerke and launched in 1983.It underwent a re-fit between 2007 and 2014 to extend its usefulness by some 30 years.

(Phys.org) —A team of researchers working in China has found evidence to suggest that stars that exist in metal-rich galactic areas tend to explode more violently when they go supernova, than do stars that explode in less metal-rich areas. In their paper published in the journal Science, describing their research, the team details how after analyzing data from the remnants of 188 type 1a supernovas, they found that those stars that existed in metal-rich areas and maybe in younger systems, tended to produce more violent explosions and associated diverse spectral features.

Credit: NASA/MPIA/Calar Alto Observatory, Oliver Krause et al. © 2013 Phys.org More information: Evidence for Two Distinct Populations of Type Ia Supernovae, Science DOI: 10.1126/science.1231502ABSTRACTType Ia supernovae (SNe Ia) have been used as excellent standardizable candles for measuring cosmic expansion, but their progenitors are still elusive. Here, we report that the spectral diversity of SNe Ia is tied to their birthplace environments. We find that those with high-velocity ejecta are substantially more concentrated in the inner and brighter regions of their host galaxies than are normal-velocity SNe Ia. Furthermore, the former tend to inhabit larger and more-luminous hosts. These results suggest that high-velocity SNe Ia likely originate from relatively younger and more metal-rich progenitors than normal-velocity SNe Ia, and are restricted to galaxies with substantial chemical evolution. Scientists have come to believe that supernovas come about in a process that involves a white dwarf. But because a single white dwarf isn’t large enough to set off an explosion, they believe a second star must be involved as well—either another white dwarf as a binary system or via accretion of material by a companion star. Researchers can’t tell using current methods which was involved when studying particular supernovas. In this new effort, the researchers believe they might have found a way to do so.By studying and comparing the spectral features of 188 type 1a supernovas and the galactic geography of the area in which they exploded, the researchers discovered what they believe is a pattern that they claim hints at the nature of the progenitor star that led to the explosion—those in metal-rich areas tended to produce more violent explosions. This suggest it’s more likely that the more violent explosions are the result of a white dwarf pulling mass from a companion star—one similar to our own, or perhaps a red giant—than the result of a binary white dwarf system exploding.Understanding the nature of supernovas is critical to understanding the universe in general, as they are used to measure distances between objects—such measurements have led to the discovery that the universe is expanding, for example. For that reason, it would be helpful to know which sorts of stars lead to their creation and why they behave the way they do when they explode. This new research appears to be one more step in that direction. Journal information: Science This document is subject to copyright.

Citation: Fine-tuning organic circuits: Monolayer terminal groups and molecular junctions (2015, April 3) retrieved 18 August 2019 from https://phys.org/news/2015-04-fine-tuning-circuits-monolayer-terminal-groups.html Journal information: Journal of the American Chemical Society One way to quantitatively compare one monolayer to another is to measure electron tunneling between the electrode and the junction point at the terminal end of the monolayer. Lead author, Kung-Ching Liao of George M. Whitesides’s group at Harvard University investigated whether decreasing the strength of the interaction between the monolayer’s terminal group and the Ga2O3 interface would decrease the tunneling current density of the monolayer. Their work was published in the Journal of the American Chemical Society.Prior studies by Whitesides’s group looked at how electron tunneling changes when the atom that is coordinated to the metal electrode (the anchor) is changed, or when the organic components (the backbone) between the anchor and the terminal group are changed. Their prior research revealed that increasing the strength of the terminal group interaction with Ga2O3 did not increase tunneling current density; however, decreasing the interaction between the terminal group and Ga2O3 junction seemed to decrease it. In this study, Liao et al. sought to investigate the mechanism for this decrease in tunneling current density.To understand this mechanism, they needed to make a direct comparison between two similar monolayers and their terminal groups. They chose to compare a monolayer comprised of C-H bonds with a monolayer that has some or all C-H bonds replaced with C-F bonds. The C-F bond is less polarizable than the C-H bond and has a longer bond length than C-H. Additionally, changing the hydrogens on an aliphatic carbon chain to fluorine decreases the energy of the HOMO and, in a monolayer, disrupts van der Waals interactions between alkyl chains. By investigating the effects of changing these factors, Liao et al. were able to discern the primary cause for the change in electron tunneling density.They found that changing the backbone from (CH2)n to (CF2)n had a small, but noticeable effect on the tunneling density. This effect was not enough to account for the differences noted in prior experiments. However, when they changed the terminal group from CH3 to CF3, they found that this factor alone, accounted for the change in electron tunneling density. Whether the backbone was an n-alkyl chain or para-substituted omega-tolyl-alkanoates or oligophenyl carboxylates, the rate of charge transport across the CF3 terminal group and Ga2O3 from the EGaIn tip differed from the CH3 equivalent by a factor of 25 to 30. This discovery allows for additional fine-tuning of an organic circuit by selecting a particular backbone and anchor with desirable electronic properties. It also sheds light on the importance of the terminal group junction interaction. (Phys.org)—Self-assembled monolayers are organic molecules that spontaneously coordinate to a metal surface. If this metal surface is an electrode, then a current can pass through the organic monolayer and interact with a second electrode on the terminal side of the molecule. This current can be controlled by changing the characteristics of the organic molecule, such as making it longer or adding polar substituents or other functional groups. This tailoring of organic circuits is part of a bigger project of creating organic-based electronics. This document is subject to copyright.

Am. Chem. Soc., 2015, 137 (11), pp 3852–3858. DOI: 10.1021/jacs.5b00137AbstractThis paper describes the influence of the substitution of fluorine for hydrogen on the rate of charge transport by hole tunneling through junctions of the form AgTSO2C(CH2)n(CF2)mT//Ga2O3/EGaIn, where T is methyl (CH3) or trifluoromethyl (CF3). Alkanoate-based self-assembled monolayers (SAMs) having perfluorinated groups (RF) show current densities that are lower (by factors of 20–30) than those of the homologous hydrocarbons (RH), while the attenuation factors of the simplified Simmons equation for methylene (β = (1.05 ± 0.02)nCH2–1) and difluoromethylene (β = (1.15 ± 0.02)nCF2–1) are similar (although the value for (CF2)n is statistically significantly larger). A comparative study focusing on the terminal fluorine substituents in SAMs of ω-tolyl- and -phenyl-alkanoates suggests that the C–F//Ga2O3 interface is responsible for the lower tunneling currents for CF3. The decrease in the rate of charge transport in SAMs with RF groups (relative to homologous RH groups) is plausibly due to an increase in the height of the tunneling barrier at the T//Ga2O3 interface, and/or to weak van der Waals interactions at that interface.
