Nanotechnology Institute, TechnionOrganizer Department of Chemical and Biological PhysicsHomepage Contact Abstract Show full text abstract about The field of crystal growth and design has been researched t...» The field of crystal growth and design has been researched thoroughly, specifically the ability to form crystals with tunable dimensions, morphologies, and functional properties. Notably, various crystallographic defects have been found to enhance material properties. For instance, atomic doping alters electrical properties, screw dislocations facilitate spiral crystal growth, while dislocation outcrops and vacancies enhance catalytic activity and strengthen materials. In this talk, I will show how such crystal defects can be utilized to fine-tune a range of physical properties in crystals and act as templates for their growth. I will also highlight examples of crystals formed in nature that serve as a source of inspiration for the design of novel bio-inspired materials with enhanced functional properties. -

SeminarContact Abstract Show full text abstract about Agreement testing (aka direct product testing), checks if co...» Agreement testing (aka direct product testing), checks if consistent local information reveals global structure. Beyond its theoretical connections to probabilistic checkable proofs (PCPs), constructing agreement testers is a fundamental combinatorial question that has exciting applications in coding theory and hardness amplification.
In recent work we construct new derandomized `1%-regime' agreement tests. Derandomization of these tests is an important stepping stone towards derandomizing many PCPs, such as the parallel repetition PCP.
We will define agreement tests and give some background on their importance. Then we will see a surprising connection between agreement testing to a problem in algebraic topology. Finally, we will discuss how strong group theoretic tools solve this problem and lead to our construction.
Based on joint work with Irit Dinur and Alex Lubotzky.

Err...» Membrane proteins (MPs) navigate challenging biogenesis. Errors in this process are rigorously surveilled by cellular quality control to eliminate faulty MPs. The first critical challenge of this surveillance is the accurate recognition of misfolded proteins. However, how this recognition is achieved for MPs remains poorly defined. Here we reveal the specificity mechanism of FtsH, the major quality control protease clearing faulty MPs in Escherichia coli. Analyzing the in vivo degradation of two substrates, we show that lipid-facing polar residues direct substrates to FtsH-mediated degradation. Such polar residues are typically buried in the structural cores of folded MPs, and their exposure to the membrane may thus signify misfolding and flag proteins for degradation. Remarkably, lipid-facing polar residues are sufficient for recognition and can target even folded MPs for degradation. The degradation depends on the FtsH transmembrane domain. Thus, MP misfolding is sensed within the membrane to maintain a healthy membrane proteome. -

Data Drought in the Humid Tropics: How to Overcome the Cloud Barrier in Greenhouse Gas Remote Sensing

California Institute of TechnologyOrganizer Department of Earth and Planetary SciencesContact Abstract Show full text abstract about Quantifying land-atmosphere fluxes of carbon-dioxide (CO2) ...» Quantifying land-atmosphere fluxes of carbon-dioxide (CO2)
and methane (CH4) is essential for evaluating carbonclimate
feedbacks. Greenhouse gas satellite missions aim to
provide global observational coverage of greenhouse gas
concentrations and thus improve inversions of landatmosphere
exchange fluxes. However, in key regions such
as the humid tropics current missions obtain very few valid
measurements. Leveraging recent advances in the global
analysis of high-resolution optical imagery on cloudcomputing
platforms and deep learning algorithms for cloud
segmentation, we quantitatively diagnose the sources for
low data yields in the tropics. We find that the main cause for
low data yields are frequent shallow cumulus clouds. We
find that increasing the spatial resolution of observations to
200 m would increase yields by 2–3 orders of magnitude
and allow regular measurements in the wet season. Thus,
the key to effective tropical greenhouse gas observations
likely lies in regularly acquiring high-spatial resolution data. -

e.g., compact particle accelerators, inertial fusion and laboratory astrophysics. The first has
known rapid progress, in terms of current, energy, stability; fusion has gone through a historic
step, with the news of ignition being achieved at NIF in 2022; and laboratory astrophysics has
known also spectacular developments, demonstrating the possibility to perform fully scalable
experiments relevant to various objects such as forming stars and supernovae. A particularly
interesting aspect is that all these fields are strongly synergistic, i.e., that advances in one can
push the others as well. I will present examples of such synergies, through recent results
we have obtained in all these domains, and in particular how ultra-bright neutron beams
can be developed using latest generation multi-PW lasers [1,2]. These could open interesting
perspectives in terms of cargo inspection, but also for fusion plasma measurements.
I will also show how fusion can benefit from external magnetization [3]. Finally, I will discuss
advances in laboratory astrophysics, particularly the first-stage acceleration of ions leading to
cosmic rays [4,5], understanding the universal nature of collimated outflows in the Universe [6],
and probing the intricacy of 3D magnetic reconnection [7]

The integration of vision into LLMs through VLMs has enabled these models to "see" and reason over visual content. However, these VLMs possess generic knowledge, lacking a personal touch. This raises an intriguing question: can we equip these models with the ability to comprehend and utilize user-specific concepts, tailored specifically to you? Can we ask the model questions about you, such as what you are wearing or what your friend is doing in the image? In this talk, we will explore how we can personalize VLMs to each user, offering more meaningful interactions that better reflect individual experiences and relationships.

Israel Oceanographic and Limnological Research, The Yigal Alon Kinneret Limnological LaboratoryOrganizer Department of Earth and Planetary SciencesContact Abstract Show full text abstract about Located in a highly sensitive subtropical climate area and a...» Located in a highly sensitive subtropical climate area and a densely populated area, Lake Kinneret is poised to undergo both natural and human-induced transformations in the coming decades. The lake is thermally stratified throughout most of the year and mixes thoroughly each winter when the epilimnion (upper layer) water temperature reaches equilibrium with the hypolimnion (bottom layer) water temperature by surface cooling and turbulence. Both the stratified and the fully mixed periods has a significant role in the Kinneret’s ecological system.
Observation shows that air above the Lake is warming in a rate of 0.4oC/decade, while the epilimnion and hypolimnion are warming in a rate of 0.3oC/decade and 0.1oC/decade, respectively, for the last 50 years. Therefore, stratification strength and duration is anticipated to change and impact the lake’s ecosystem.
Additionally, the sequence of drought periods and the expected future rise in water demands from Lake Kinneret formed the basis for the government's decision to channel desalinated water, via the natural course of the Tzalmon Stream, to the lake to ensure its operational functionality at high levels.
Using a 3D hydrodynamic model forced by short and long-term forecasts the above scenarios are examined and analyzed. A simulation forced by regional atmospheric RCP4.5 climate change scenario spanning from 2010-2070 show continuous warming followed by abrupt cooling of the lake water around the year 2065. This result, presumably due to enhanced latent heat loss, suggest a restrain the dramatic anticipated change in the lake stratification.
