It’s important to allow people to adapt the output to their needs, edit the experience, or even turn it off. AI-driven products are probabilistic by nature and the experience won’t be perfect for everyone, every time. With this in mind, we knew that we needed to give each individual some control over their experience. When we expanded our reminiscing features and automatically brought more photos and videos out of obscurity and put them front and center in the Photos app, the impact of getting things wrong became much higher. Some memories are intensely sad, upsetting, or painful - such as photos of an ex-partner or a loved one that has died. In addition, reminiscing is personal and not all memories are welcome. To create an engaging reminiscing experience that everyone would enjoy we needed to make tough decisions about what types of content to include or filter out. That said, Memories needed to be enjoyable for everyone - no matter the size of their photo library, whether or not they travel, have kids or pets, or if they take hundreds of pictures a week or a few pictures a month. Personally, I love that these show how someone has grown over time, like this one that shows my daughter at age one and age three. If face grouping is on, AI creates collages featuring a recent photo of someone next to an older photo of them in a similar pose. We use AI to automatically combine photos and videos into a short movie set to music and generate animations from photo bursts. It also powers features that go beyond search and organization. In Google Photos we use AI to make your images easier to search and organize by people, places, and things. That said, because a large, diverse group of people use Photos, and because reminiscing is so personal, we knew that we’d need to give individuals control over their experience. We on the Google Photos team saw an opportunity to reconnect people with their memories, and we used AI to understand what photos are meaningful and worthy of reminiscing. Still we took them for a reason - to document, to share and to remember those meaningful moments. Special moments that we capture are quickly buried in an overwhelming black hole of digital obscurity, and the majority of photos backed up in Google Photos might never be viewed again. It’s great - so many pictures□ and overwhelming - so many pictures □. ![]() Now that we carry high-quality cameras in our pockets to snap selfies and take videos of our cats, our photo and video libraries are getting huge. If you were alive before smartphones and digital cameras, you might remember when your photographic memories were in physical photo albums or a shoebox that you thumbed through when you got the urge to reminisce.

Examples include Microsoft SharePoint Server, Exchange Server, and others.Īttackers who compromise a business-critical network often look for and attack domain controllers on the enterprise network as Active Directory contains the “keys to the kingdom” in the identity information it contains. In addition, most Microsoft solutions use Active Directory permissions for built-in roles and services provided in the application. Most of the traditional Microsoft solutions in the enterprise integrate with Active Directory to pull permissions from the central identity repository provided by Active Directory services.

The boa first strikes at the prey, grabbing it with its teeth it then proceeds to constrict the prey until death before consuming it whole. However, they do hunt, particularly in regions with a low concentration of suitable prey, and hunting generally occurs at night. This may serve to confuse potential predators and prey items alike. The creature looks much like a miniature anaconda or boa constrictor, but the tail is thickened, slightly resembling a second head. Boa constrictors are ambush predators, so often lie in wait for an appropriate prey to come along, when they attack. The rubber boa has some ability to regulate its own temperature, which is rare in reptiles. It makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might be otherwise. curved teeth, the boa quickly wraps a portion of its body around the animal. In fact, many male Common Boas never get over. Boa constrictors give birth to live young as do 30 of the worlds snakes. Like all snakes, Boa constrictors in a shed cycle are more unpredictable, because of the substance that lubricates between the old skin and the new one. Boa imperator Boas Constrictors have fewer bones in their head and also fewer teeth compared to Ball Pythons. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. Examination under anesthesia revealed two firm pink masses within the oral cavity. These snakes strike when they perceive a threat. A 17-yr-old boa constrictor (Boa constrictor constrictor) presented initially with diffuse gingival swelling, loose teeth, and loss of body condition. Boa constrictors often occupy the burrows of medium-sized mammals, where they can hide from potential predators. While the boa constrictor does have teeth and is capable of biting, it rarely does so. ![]() Tiger Attacked by a Boa Constrictor Hunting Hunt predator prey endangered.

If required, frozen foods can be vitaminized with suitable. Usually, can be fed with rodents or frozen rabbits of suitable size, that thaw quickly (for example, in warm water) and are brought to an approximate body temperature (35 40 ☌) before feeding them. Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate. The Boa constrictor feeds mainly on mammals, reptiles and birds in the wild. ![]() ![]() ![]() If you've never taken the time to enjoy the unlimited images that can be generated from a Mandelbrot set, then this is mostly how you get to spend the first few minutes.

Sousa A, Sousa F, Queiroz JA (2012) Advances in chromatographic supports for pharmaceutical-grade plasmid DNA purification. This behaviour can be linked to the presence of the more hydrophobic phenyl group in Capto Adhere, leading to stronger retention of ssDNA molecules, which have a more hydrophobic character due to a higher degree of base exposure. Another pronounced difference between the resins was observed in the inverted elution of ss- and dsDNA, where ssDNA eluted at 2.88 M NaCl on Capto Adhere, while on Capto Q ImpRes ssDNA eluted already at 1.47 M NaCl. This recognition was not observed for Capto Adhere. Capto Q ImpRes provided a recognition for guanylate bases when samples of deoxynucleotides or poly(dG) were examined. ![]() All deoxynucleotides and DNAs tested bound strongly to the chromatographic materials and could be eluted by a linear gradient of increasing NaCl concentration. These variations in biophysical properties have been utilized for comparative separations on these two resins. The intrinsic differences between single- and double-stranded DNAs are related to charge, hydrophobicity, size and three-dimensional structure. Capto Adhere carries a multimodal ligand which combines strong anion with aromatic recognition, while Capto Q ImpRes is a strong anion exchanger with a chemically similar ligand, but without a phenyl group. Binding of the MAb, purified from CHO cell supernatant by protein A, to Capto adhere ImpRes was therefore performed in 40 mM sodium phosphate, pH 7.8.The differences in chromatographic behaviour of individual deoxynucleotides as well as small single-stranded and double-stranded DNA molecules have been examined for two resins from the Capto family: Capto Adhere and Capto Q ImpRes. The results show that the highest binding capacities were obtained at high pH and low salt concentration, while a shorter residence time reduced the capacity (Figure 1). The influence of pH and NaCl concentration on static binding capacity and dynamic binding capacity of Capto adhere ImpRes was determined in PreDictor™ 96-well filter plates and by design of experiment (DoE) in Tricorn™ 5/50 columns, respectively. Here we describe a workflow for method development of a polishing step for a MAb in B/E mode using Capto adhere ImpRes. The medium allows operation in either bind-elute (B/E) or flow-through (FT) modes. One of these options is Capto adhere ImpRes, a cost-effective and flexible multimodal anion exchange chromatography medium designed for high-resolution polishing of MAbs. GE Healthcare Life Sciences’ MAb toolbox employs protein A chromatography media (resins) as well as a wide range of options for polishing purification steps. A platform approach for MAb purification is desirable as it saves both time and money in process development. |
