摘要:The number of acutely food insecure people worldwide has doubled since 2017, increasing demand for early warning systems (EWS) that can predict food emergencies. Advances in computational methods, and the growing availability of near- real time remote sensing data, suggest that big data approaches might help meet this need. But such models have thus far exhibited low predictive skill with respect to subpopulation- level acute malnutrition indicators. We explore whether updating training data w...

摘要:Characterizing the conformational ensemble of biomolecular systems is key to understand their functions. Cryoelectron microscopy (cryo-EM) captures two-dimensional snapshots of biomolecular ensembles, giving in principle access to thermodynamics. However, these images are very noisy and show projections of the molecule in unknown orientations, making it very difficult to identify the biomolecule's conformation in each individual image. Here, we introduce cryo-EM simulation-based inference (cry...

摘要:Jansen's metaphyseal chondrodysplasia (JMC) is a rare disorder caused by activating mutations in the parathyroid hormone (PTH)/PTH-related peptide (PTHrP) receptor (PTH1R). Patients exhibit short stature, dysmorphic bones, and severe growth plate abnormalities, as well as hypercalcemia, hypercalciuria, hypophosphatemia, and reduced plasma PTH levels. Humanized PTH1R (hPTH1R) mice expressing the H223R-hPTH1R JMC mutation die early without breeding. We therefore generated and characterized a sta...

摘要:Colloidal nanoparticles are of great interest in modern science and industry. However, the thermodynamic mechanism and dynamics of nanoparticle growth have yet to be understood. Addressing these issues, we tracked hundreds of in-situ growth trajectories of a nanoparticle ensemble using liquid-phase TEM and found that the nanoparticle growth, including coalescence, exhibits nanoparticle size-dependent multiphasic dynamics, unexplainable by current theories. Motivated by this finding, we develop...

摘要:Several cross-country examinations have found larger gender differences in Western countries. More recently, it has been argued, from an evolutionary standpoint, that equality may paradoxically increase gender differences, because it provides more freedom for men and women to pursue innate preferences. However, this paradox has primarily been examined with this cross-country methodology, opening up for other cultural differences to drive the results. For instance, measures developed in Protest...

摘要:A universal response of plants to environmental stresses is the activation of plasma membrane (PM) phospholipase C, which hydrolyzes phosphoinositides to produce soluble inositol phosphate and diacylglycerol (DAG). Because of their conical shape, DAG amounts have to be tightly regulated or they can destabilize membranes. We previously showed that upon stress, Synaptotagmin1 (SYT1) transports DAG from the PM to the endoplasmic reticulum (ER) at ER-PM Contact Sites (CS). Here, we addressed the f...

摘要:Since our first steps in life, we are forming incidental associations between diverse stimuli across various sensory modalities that influence our future choices and facilitate adaptation to environmental fluctuations. Daily behavior is usually governed by indirect incidental associations among sensory cues that have never been explicitly paired with a reinforcer. This phenomenon, known as higher-order conditioning, can be systematically investigated in laboratory animals through specific beha...

摘要:Historically, endocrine cells were perceived to coordinate their output in a uniform manner. Recently however, single-cell technologies have uncovered heterogeneity within these populations, indicating that individual cells may operate as independently regulated units. Using high-resolution tools such as single-molecule fluorescent in situ hybridization (sm-FISH) and single-cell RNA sequencing (scRNA-seq), we investigated the contributions of individual and the collective of fetal Leydig cells...

摘要:The rapidly expanding lithium- ion battery (LIB) market has heightened the demand for efficient diagnostics for in- use cells and the reliable grading of used cells. Various purpose- built analysis tools and statistical algorithms have been developed, but often rely on redundant instrumentation and computationally intensive procedures. Here, we propose using the variance of the capacity difference between 0.2C and 1C, Var(Delta Q0.2C- 1C(V)), based on the strong correlation between the interfa...

摘要:Empirical slip-rate-and state-dependent friction laws and linear fracture mechanics constitute popular approaches to explaining earthquakes. However, the physics underlying friction laws remain elusive and fracture mechanics does not specify fault strength at the various conditions relevant to crustal faulting. Here, we introduce a physical constitutive framework that augments the traditional approaches by incorporating the real area of contact as the state variable. The physical model explain...
