iPhone 14 and iPhone 14 Plus are designed to minimize their impact on the environment, including antenna lines that use upcycled plastic water bottles that have been chemically transformed into a stronger, higher-performance material. iPhone 14 models also use 100 percent recycled rare earth elements in all magnets, including those used in MagSafe, and 100 percent recycled tungsten in the Taptic Engine. Both models also include 100 percent recycled tin in the solder of multiple printed circuit boards, and 100 percent recycled gold in the plating of multiple printed circuit boards and in the wire of all cameras. Fiber-based packaging does not use outer plastic wrap, bringing Apple closer to its goal of completely removing plastic from all packaging by 2025.
Starting today, customers can pre-order all models of the advanced iPhone 14 lineup on apple.com and on the Apple Store app. iPhone 14, iPhone 14 Pro, and iPhone 14 Pro Max will be available in stores and for delivery starting Friday, September 16. iPhone 14 Plus will be available in stores and for delivery beginning Friday, October 7.
It's September, which means it's time for Apple to update the iPhone. This year brings the iPhone 14 and 14 Pro, handsets that look quite a bit like last year's 13 series on the outside, though there are some big changes inside, especially with the 14 Pro and 14 Pro Max. If you're interested in learning about the phones in general, we've got you covered; here we'll take a close look at the cameras.
Like the iPhone 13, the "regular" iPhone 14 models sport dual cameras, one with an ultra-wide view and another with the classic wide angle (26mm) that's become the de facto standard view for smartphones. The front-facing selfie camera has an f/2.2 lens for FaceTime chats and selfies.
For video, the basic iPhone 14 models support 4K60 recording in SDR or Dolby Vision HDR, the same as last time. Cinematic mode gets an upgrade, though. The feature made its debut last year and brings the bokeh effect to video, but was limited to 1080p24 with the 13 series. With the iPhone 14 it gets an upgrade to 4K, and you can pick between the classic 24fps look or more video-like 30fps, both with Dolby Vision color.
This paper presents a new deep learning method that predicts contacts by integrating both evolutionary coupling (EC) and sequence conservation information through an ultra-deep neural network formed by two deep residual neural networks. The first residual network conducts a series of 1-dimensional convolutional transformation of sequential features; the second residual network conducts a series of 2-dimensional convolutional transformation of pairwise information including output of the first residual network, EC information and pairwise potential. By using very deep residual networks, we can accurately model contact occurrence patterns and complex sequence-structure relationship and thus, obtain higher-quality contact prediction regardless of how many sequence homologs are available for proteins in question.
Our method greatly outperforms existing methods and leads to much more accurate contact-assisted folding. Tested on 105 CASP11 targets, 76 past CAMEO hard targets, and 398 membrane proteins, the average top L long-range prediction accuracy obtained by our method, one representative EC method CCMpred and the CASP11 winner MetaPSICOV is 0.47, 0.21 and 0.30, respectively; the average top L/10 long-range accuracy of our method, CCMpred and MetaPSICOV is 0.77, 0.47 and 0.59, respectively. Ab initio folding using our predicted contacts as restraints but without any force fields can yield correct folds (i.e., TMscore>0.6) for 203 of the 579 test proteins, while that using MetaPSICOV- and CCMpred-predicted contacts can do so for only 79 and 62 of them, respectively. Our contact-assisted models also have much better quality than template-based models especially for membrane proteins. The 3D models built from our contact prediction have TMscore>0.5 for 208 of the 398 membrane proteins, while those from homology modeling have TMscore>0.5 for only 10 of them. Further, even if trained mostly by soluble proteins, our deep learning method works very well on membrane proteins. In the recent blind CAMEO benchmark, our fully-automated web server implementing this method successfully folded 6 targets with a new fold and only 0.3L-2.3L effective sequence homologs, including one β protein of 182 residues, one α+β protein of 125 residues, one α protein of 140 residues, one α protein of 217 residues, one α/β of 260 residues and one α protein of 462 residues. Our method also achieved the highest F1 score on free-modeling targets in the latest CASP (Critical Assessment of Structure Prediction), although it was not fully implemented back then.
Protein contact prediction and contact-assisted folding has made good progress due to direct evolutionary coupling analysis (DCA). However, DCA is effective on only some proteins with a very large number of sequence homologs. To further improve contact prediction, we borrow ideas from deep learning, which has recently revolutionized object recognition, speech recognition and the GO game. Our deep learning method can model complex sequence-structure relationship and high-order correlation (i.e., contact occurrence patterns) and thus, improve contact prediction accuracy greatly. Our test results show that our method greatly outperforms the state-of-the-art methods regardless how many sequence homologs are available for a protein in question. Ab initio folding guided by our predicted contacts may fold many more test proteins than the other contact predictors. Our contact-assisted 3D models also have much better quality than homology models built from the training proteins, especially for membrane proteins. One interesting finding is that even trained mostly with soluble proteins, our method performs very well on membrane proteins. Recent blind CAMEO test confirms that our method can fold large proteins with a new fold and only a small number of sequence homologs.
De novo protein structure prediction from sequence alone is one of most challenging problems in computational biology. Recent progress has indicated that some correctly-predicted long-range contacts may allow accurate topology-level structure modeling [1] and that direct evolutionary coupling analysis (DCA) of multiple sequence alignment (MSA) may reveal some long-range native contacts for proteins and protein-protein interactions with a large number of sequence homologs [2, 3]. Therefore, contact prediction and contact-assisted protein folding has recently gained much attention in the community. However, for many proteins especially those without many sequence homologs, the predicted contacts by the state-of-the-art predictors such as CCMpred [4], PSICOV [5], Evfold [6], plmDCA[7], Gremlin[8], MetaPSICOV [9] and CoinDCA [10] are still of low quality and insufficient for accurate contact-assisted protein folding [11, 12]. This motivates us to develop a better contact prediction method, especially for proteins without a large number of sequence homologs. In this paper we define that two residues form a contact if they are spatially proximal in the native structure, i.e., the Euclidean distance of their Cβ atoms less than 8Å [13]. 2ff7e9595c
