I caught this just down the street from that garden, that's the facade of the Vet Research Tower in the background
#photo #photography #cornell

A purple flower that's got several rows of ray petals seen from the side with just a few yellow fibers sticking out from the disc in the middle. A few long green leaves are sticking up from below, in the background are vertical stripes, some reflective of a glass and steel building.

SEA THRIFT!!!!!!!!111 😍😍😍 #BloomScrolling #CaliforniaNatives #NatureyCrap #SanFranciscoHellscape

Close up photo of an Armeria maritima flower cluster floating delicately on its long stalk, with the bulk of the plant out of focus in the background. The small flowers are a very cheerful pink and have 5 petals. There are maybe 20 or so individual flowers all crammed together into a bright pink ball at the end of a long, slender green stalk growing out of the middle of the prostrate plant. The plant is made up of numerous very thin and long, spear-like dark green leaves - almost like a spiky c…

PET Tracer Separation Using Conditional Diffusion Transformer with Multi-latent Space Learning
In clinical practice, single-radiotracer positron emission tomography (PET) is commonly used for imaging. Although multi-tracer PET imaging can provide supplementary information of radiotracers that are sensitive to physiological function changes, enabling a more comprehensive characterization of physiological and pathological states, the gamma-photon pairs generated by positron annihilation reactions of different tracers in PET imaging have the same energy, making it difficult to distinguish t…

$La_3Pd_2NaO_9$: A High-Valent Insulating Palladate
A high-valent palladate, $La_3Pd_2NaO_9$, has been synthesized for the first time. Single crystals with dimensions of 20 $μ$m on edge were successfully grown using the flux method at 420 $^o$C and 70 bar oxygen pressure. Energy dispersive spectroscopy (EDS) and inductively coupled plasma mass spectroscopy (ICP) measurements show that the atomic ratio of La: (Pd+Na) is 3: 3 and Pd: Na is 2: 1. X-ray photoelectron spectroscopy (XPS) measurements show that the oxidation state of Pd is dominated b…

A rose drying out naturally in a pot inside.
#wildlife #photography

A subtle orangey/yellow rose is all dried and crinkely; it sits in a blue ceramic pot with some other cuttings. There's some tiling behind it. All the petals are wonderfully twisted and the centre is very complicated

Flying choir boy vibes tbh #BloomScrolling #CaliforniaNatives #SanFranciscoHellscape

Close up photo of a Romneya coulteri blossom looking like a choir boy who’s about to take flight. The flower is large, floppy, and has 3 or 4 large white petals, with an orange yellow fuzzy ball in the centre that looks like the choir boy’s head. Behind the flower many other Romneya stalks are visible, many with unopened flower buds and/or opened blossoms on them.

A tissue and cell-level annotated H&E and PD-L1 histopathology image dataset in non-small cell lung cancer
The tumor immune microenvironment (TIME) in non-small cell lung cancer (NSCLC) histopathology contains morphological and molecular characteristics predictive of immunotherapy response. Computational quantification of TIME characteristics, such as cell detection and tissue segmentation, can support biomarker development. However, currently available digital pathology datasets of NSCLC for the development of cell detection or tissue segmentation algorithms are limited in scope, lack annotations o…

Disruption of parkinsonian brain oscillations
Deep brain stimulation (DBS) is an advanced surgical treatment for the symptoms of Parkinson's disease (PD), involving electrical stimulation of neurons within the basal ganglia region of the brain. DBS is traditionally delivered in an open-loop manner using fixed stimulation parameters, which may lead to suboptimal results. In an effort to overcome these limitations, closed loop DBS, using pathological subthalamic beta (13--30 Hz) activity as a feedback signal, offers the potential to adapt DB…
