text: We perform a diagrammatic analysis of the energy of a mobile impurity immersed
in a strongly interacting two-component Fermi gas to second order in the impurity-bath
interaction. These corrections demonstrate divergent behavior in the limit of
large impurity momentum. We show the fundamental processes responsible for these
logarithmically divergent terms. We study the problem in the general case without
any assumptions regarding the fermion-fermion interactions in the bath. We show
that the divergent term can be summed up to all orders in the Fermi-Fermi interaction
and that the resulting expression is equivalent to the one obtained in the few-body
calculation. Finally, we provide a perturbative calculation to the second order
in the Fermi-Fermi interaction, and we show the diagrams responsible for these
terms.

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.

text: Characterizing the prevalence and properties of faint active galactic nuclei
(AGNs) in the early Universe is key for understanding the formation of supermassive
black holes (SMBHs) and determining their role in cosmic reionization. We perform
a spectroscopic search for broad Hα emitters at z ≈ 4–6 using deep JWST/NIRCam
imaging and wide field slitless spectroscopy from the EIGER and FRESCO surveys.
We identify 20 Hα lines at z = 4.2–5.5 that have broad components with line widths
from ∼1200–3700 km s−1, contributing ∼30%–90% of the total line flux. We interpret
these broad components as being powered by accretion onto SMBHs with implied masses
∼107–8M⊙. In the UV luminosity range MUV,AGN+host = −21 to −18, we measure number
densities of ≈10−5 cMpc−3. This is an order of magnitude higher than expected
from extrapolating quasar UV luminosity functions (LFs). Yet, such AGN are found
in only <1% of star-forming galaxies at z ∼ 5. The number density discrepancy
is much lower when compared to the broad Hα LF. The SMBH mass function agrees
with large cosmological simulations. In two objects, we detect complex Hα profiles
that we tentatively interpret as caused by absorption signatures from dense gas
fueling SMBH growth and outflows. We may be witnessing early AGN feedback that
will clear dust-free pathways through which more massive blue quasars are seen.
We uncover a strong correlation between reddening and the fraction of total galaxy
luminosity arising from faint AGN. This implies that early SMBH growth is highly
obscured and that faint AGN are only minor contributors to cosmic reionization.

text: The fungal bioluminescence pathway can be reconstituted in other organisms
allowing luminescence imaging without exogenously supplied substrate. The pathway
starts from hispidin biosynthesis—a step catalyzed by a large fungal polyketide
synthase that requires a posttranslational modification for activity. Here, we
report identification of alternative compact hispidin synthases encoded by a phylogenetically
diverse group of plants. A hybrid bioluminescence pathway that combines plant
and fungal genes is more compact, not dependent on availability of machinery for
posttranslational modifications, and confers autonomous bioluminescence in yeast,
mammalian, and plant hosts. The compact size of plant hispidin synthases enables
additional modes of delivery of autoluminescence, such as delivery with viral
vectors.

text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.
