text: We show that matrix elements of functions of N × N Wigner matrices fluctuate
on a scale of order N−1/2 and we identify the limiting fluctuation. Our result
holds for any function f of the matrix that has bounded variation thus considerably
relaxing the regularity requirement imposed in [7, 11].

text: 'Aim: The present study was to compare the effects of nicotinic acid and nicotinamide
on the plasma methyl donors, choline and betaine. Methods: Thirty adult subjects
were randomly divided into three groups of equal size, and orally received purified
water (C group), nicotinic acid (300 mg, NA group) or nicotinamide (300 mg, NM
group). Plasma nicotinamide, N 1-methylnicotinamide, homocysteine, betaine and
choline levels before and 1.5-h and 3-h post-dosing, plasma normetanephrine and
metanephrine concentrations at 3-h post-dosing, and the urinary excretion of N
1-methyl-2-pyridone-5-carboxamide during the test period were examined. Results:
The level of 3-h plasma nicotinamide, N 1-methylnicotinamide, homocysteine, the
urinary excretion of N 1-methyl-2-pyridone-5-carboxamide and pulse pressure (PP)
in the NM group was 221%, 3972%, 61%, 1728% and 21.2% higher than that of the
control group (P < 0.01, except homocysteine and PP P < 0.05), while the
3-h plasma betaine, normetanephrine and metanephrine level in the NM group was
24.4%, 9.4% and 11.7% lower (P < 0.05, except betaine P < 0.01), without
significant difference in choline levels. Similar but less pronounced changes
were observed in the NA group, with a lower level of 3-h plasma N 1-methylnicotinamide
(1.90 ± 0.20 μmol/l vs. 3.62 ± 0.27 μmol/l, P < 0.01) and homocysteine (12.85
± 1.39 μmol/l vs. 18.08 ± 1.02 μmol/l, P < 0.05) but a higher level of betaine
(27.44 ± 0.71 μmol/l vs. 23.52 ± 0.61 μmol/l, P < 0.05) than that of the NM
group. Conclusion: The degradation of nicotinamide consumes more betaine than
that of nicotinic acid at identical doses. This difference should be taken into
consideration in niacin fortification. © 2016 Elsevier Ltd and European Society

text: "We present spectroscopic follow-up observations of CR7 with ALMA, targeted
at constraining the infrared (IR) continuum and [C II]158 mm line-emission at
high spatial resolution matched to the HST/WFC3 imaging. CR7 is a luminous Lyα
emitting galaxy at z = 6.6 that consists of three separated UV-continuum components.
Our observations reveal several well-separated components of [C II] emission.
The two most luminous components in [C II] coincide with the brightest UV components
(A and B), blueshifted by »150 km s−1 with respect to the\r\npeak of Lyα emission.
Other [C II] components are observed close to UV clumps B and C and are blueshifted
by »300 and ≈80 km s−1 with respect to the systemic redshift. We do not detect
FIR continuum emission due to dust with a 3σ limiting luminosity LIR T L d 35
K 3.1 10 = <´ 10 ( ) . This allows us to mitigate uncertainties in the dust-corrected
SFR and derive SFRs for the three UV clumps A, B, and C of 28, 5, and 7 M yr−1.
All clumps have [C II] luminosities consistent within the scatter observed in
the local relation between SFR and L[ ] C II , implying that strong Lyα emission
does not necessarily anti-correlate with [C II] luminosity. Combining\r\nour measurements
with the literature, we show that galaxies with blue UV slopes have weaker [C
II] emission at fixed SFR, potentially due to their lower metallicities and/or
higher photoionization. Comparison with hydrodynamical simulations suggests that
CR7ʼs clumps have metallicities of 0.1 Z Z 0.2 < < . The observed ISM structure
of CR7 indicates that we are likely witnessing the build up of a central galaxy
in the early universe through complex accretion of satellites."

text: We propose a new memetic strategy that can solve the multi-physics, complex
inverse problems, formulated as the multi-objective optimization ones, in which
objectives are misfits between the measured and simulated states of various governing
processes. The multi-deme structure of the strategy allows for both, intensive,
relatively cheap exploration with a moderate accuracy and more accurate search
many regions of Pareto set in parallel. The special type of selection operator
prefers the coherent alternative solutions, eliminating artifacts appearing in
the particular processes. The additional accuracy increment is obtained by the
parallel convex searches applied to the local scalarizations of the misfit vector.
The strategy is dedicated for solving ill-conditioned problems, for which inverting
the single physical process can lead to the ambiguous results. The skill of the
selection in artifact elimination is shown on the benchmark problem, while the
whole strategy was applied for identification of oil deposits, where the misfits
are related to various frequencies of the magnetic and electric waves of the magnetotelluric
measurements. 2016 Elsevier B.V.

text: This dissertation concerns the automatic verification of probabilistic systems
and programs with arrays by statistical and logical methods. Although statistical
and logical methods are different in nature, we show that they can be successfully
combined for system analysis. In the first part of the dissertation we present
a new statistical algorithm for the verification of probabilistic systems with
respect to unbounded properties, including linear temporal logic. Our algorithm
often performs faster than the previous approaches, and at the same time requires
less information about the system. In addition, our method can be generalized
to unbounded quantitative properties such as mean-payoff bounds. In the second
part, we introduce two techniques for comparing probabilistic systems. Probabilistic
systems are typically compared using the notion of equivalence, which requires
the systems to have the equal probability of all behaviors. However, this notion
is often too strict, since probabilities are typically only empirically estimated,
and any imprecision may break the relation between processes. On the one hand,
we propose to replace the Boolean notion of equivalence by a quantitative distance
of similarity. For this purpose, we introduce a statistical framework for estimating
distances between Markov chains based on their simulation runs, and we investigate
which distances can be approximated in our framework. On the other hand, we propose
to compare systems with respect to a new qualitative logic, which expresses that
behaviors occur with probability one or a positive probability. This qualitative
analysis is robust with respect to modeling errors and applicable to many domains.
In the last part, we present a new quantifier-free logic for integer arrays, which
allows us to express counting. Counting properties are prevalent in array-manipulating
programs, however they cannot be expressed in the quantified fragments of the
theory of arrays. We present a decision procedure for our logic, and provide several
complexity results.

text: We present a sample of ∼1000 emission-line galaxies at z = 0.4–4.7 from the
∼0.7deg2 High-z Emission-Line Survey in the Boötes field identified with a suite
of six narrow-band filters at ≈0.4–2.1 μm. These galaxies have been selected on
their Ly α (73), [O II] (285), H β/[O III] (387) or H α (362) emission line, and
have been classified with optical to near-infrared colours. A subsample of 98
sources have reliable redshifts from multiple narrow-band (e.g. [O II]–H α) detections
and/or spectroscopy. In this survey paper, we present the observations, selection
and catalogues of emitters. We measure number densities of Ly α, [O II], H β/[O III]
and H α and confirm strong luminosity evolution in star-forming galaxies from
z ∼ 0.4 to ∼5, in agreement with previous results. To demonstrate the usefulness
of dual-line emitters, we use the sample of dual [O II]–H α emitters to measure
the observed [O II]/H α ratio at z = 1.47. The observed [O II]/H α ratio increases
significantly from 0.40 ± 0.01 at z = 0.1 to 0.52 ± 0.05 at z = 1.47, which we
attribute to either decreasing dust attenuation with redshift, or due to a bias
in the (typically) fibre measurements in the local Universe that only measure
the central kpc regions. At the bright end, we find that both the H α and Ly α
number densities at z ≈ 2.2 deviate significantly from a Schechter form, following
a power law. We show that this is driven entirely by an increasing X-ray/active
galactic nucleus fraction with line luminosity, which reaches ≈100 per cent at
line luminosities L ≳ 3 × 1044 erg s−1.

text: We present the CAlibrating LYMan-α with Hα (CALYMHA) pilot survey and new
results on Lyman α (Lyα) selected galaxies at z ∼ 2. We use a custom-built Lyα
narrow-band filter at the Isaac Newton Telescope, designed to provide a matched
volume coverage to the z = 2.23 Hα HiZELS survey. Here, we present the first results
for the COSMOS and UDS fields. Our survey currently reaches a 3σ line flux limit
of ∼4 × 10−17 erg s−1 cm−2, and a Lyα luminosity limit of ∼1042.3 erg s−1. We
find 188 Lyα emitters over 7.3 × 105 Mpc3, but also find significant numbers of
other line-emitting sources corresponding to He II, C III] and C IV emission lines.
These sources are important contaminants, and we carefully remove them, unlike
most previous studies. We find that the Lyα luminosity function at z = 2.23 is
very well described by a Schechter function up to LLy α ≈ 1043 erg s−1 with L∗=1042.59+0.16−0.08
erg s−1, ϕ∗=10−3.09+0.14−0.34 Mpc−3 and α = −1.75 ± 0.25. Above LLy α ≈ 1043 erg
s−1, the Lyα luminosity function becomes power-law like, driven by X-ray AGN.
We find that Lyα-selected emitters have a high escape fraction of 37 ± 7 per cent,
anticorrelated with Lyα luminosity and correlated with Lyα equivalent width. Lyα
emitters have ubiquitous large (≈40 kpc) Lyα haloes, ∼2 times larger than their
Hα extents. By directly comparing our Lyα and Hα luminosity functions, we find
that the global/overall escape fraction of Lyα photons (within a 13 kpc radius)
from the full population of star-forming galaxies is 5.1 ± 0.2 per cent at the
peak of the star formation history. An extra 3.3 ± 0.3 per cent of Lyα photons
likely still escape, but at larger radii.

text: We study the production rate of ionizing photons of a sample of 588 Hα emitters
(HAEs) and 160 Lyman-α emitters (LAEs) at z = 2.2 in the COSMOS field in order
to assess the implied emissivity from galaxies, based on their ultraviolet (UV)
luminosity. By exploring the rest-frame Lyman Continuum (LyC) with GALEX/NUV data,
we find fesc < 2.8 (6.4) per cent through median (mean) stacking. By combining
the Hα luminosity density with intergalactic medium emissivity measurements from
absorption studies, we find a globally averaged 〈fesc〉 of 5.9+14.5−4.2 per cent
at z = 2.2 if we assume HAEs are the only source of ionizing photons. We find
similarly low values of the global 〈fesc〉 at z ≈ 3–5, also ruling out a high 〈fesc〉
at z < 5. These low escape fractions allow us to measure ξion, the number of produced
ionizing photons per unit UV luminosity, and investigate how this depends on galaxy
properties. We find a typical ξion ≈ 1024.77 ± 0.04 Hz erg−1 for HAEs and ξion
≈ 1025.14 ± 0.09 Hz erg−1 for LAEs. LAEs and low-mass HAEs at z = 2.2 show similar
values of ξion as typically assumed in the reionization era, while the typical
HAE is three times less ionizing. Due to an increasing ξion with increasing EW(Hα),
ξion likely increases with redshift. This evolution alone is fully in line with
the observed evolution of ξion between z ≈ 2 and 5, indicating a typical value
of ξion ≈ 1025.4 Hz erg−1 in the reionization era.

text: We use the hydrodynamical EAGLE simulation to study the magnitude and origin
of the scatter in the stellar mass–halo mass relation for central galaxies. We
separate cause and effect by correlating stellar masses in the baryonic simulation
with halo properties in a matched dark matter only (DMO) simulation. The scatter
in stellar mass increases with redshift and decreases with halo mass. At z = 0.1,
it declines from 0.25 dex at M200, DMO ≈ 1011 M⊙ to 0.12 dex at M200, DMO ≈ 1013
M⊙, but the trend is weak above 1012 M⊙. For M200, DMO < 1012.5 M⊙ up to 0.04
dex of the scatter is due to scatter in the halo concentration. At fixed halo
mass, a larger stellar mass corresponds to a more concentrated halo. This is likely
because higher concentrations imply earlier formation times and hence more time
for accretion and star formation, and/or because feedback is less efficient in
haloes with higher binding energies. The maximum circular velocity, Vmax, DMO,
and binding energy are therefore more fundamental properties than halo mass, meaning
that they are more accurate predictors of stellar mass, and we provide fitting
formulae for their relations with stellar mass. However, concentration alone cannot
explain the total scatter in the Mstar−M200,DMO relation, and it does not explain
the scatter in Mstar–Vmax, DMO. Halo spin, sphericity, triaxiality, substructure
and environment are also not responsible for the remaining scatter, which thus
could be due to more complex halo properties or non-linear/stochastic baryonic
effects.

text: While traditionally associated with active galactic nuclei (AGN), the properties
of the C II] (λ = 2326 Å), C III] (λ, λ = 1907, 1909 Å) and C IV (λ, λ = 1549,
1551 Å) emission lines are still uncertain as large, unbiased samples of sources
are scarce. We present the first blind, statistical study of C II], C III] and
C IV emitters at z ∼ 0.68, 1.05, 1.53, respectively, uniformly selected down to
a flux limit of ∼4 × 10−17 erg s−1 cm−1 through a narrow-band survey covering
an area of ∼1.4 deg2 over COSMOS and UDS. We detect 16 C II], 35 C III] and 17
C IV emitters, whose nature we investigate using optical colours as well as Hubble
Space Telescope (HST), X-ray, radio and far-infrared data. We find that z ∼ 0.7
C II] emitters are consistent with a mixture of blue (UV slope β = −2.0 ± 0.4)
star-forming (SF) galaxies with discy HST structure and AGN with Seyfert-like
morphologies. Bright C II] emitters have individual X-ray detections as well as
high average black hole accretion rates (BHARs) of ∼0.1 M⊙ yr−1. C III] emitters
at z ∼ 1.05 trace a general population of SF galaxies, with β = −0.8 ± 1.1, a
variety of optical morphologies, including isolated and interacting galaxies and
low BHAR (<0.02 M⊙ yr−1). Our C IV emitters at z ∼ 1.5 are consistent with young,
blue quasars (β ∼ −1.9) with point-like optical morphologies, bright X-ray counterparts
and large BHAR (0.8 M⊙ yr−1). We also find some surprising C II], C III] and
C IV emitters with rest-frame equivalent widths (EWs) that could be as large as
50–100 Å. AGN or spatial offsets between the UV continuum stellar disc and the
line-emitting regions may explain the large EW. These bright C II], C III] and
C IV emitters are ideal candidates for spectroscopic follow-up to fully unveil
their nature.

text: Recently, the C III] and C IV emission lines have been observed in galaxies
in the early Universe (z > 5), providing new ways to measure their redshift and
study their stellar populations and active galactic nuclei (AGN). We explore the
first blind C II], C III] and C IV survey (z ∼ 0.68, 1.05, 1.53, respectively)
presented in Stroe et al. (2017). We derive luminosity functions (LF) and study
properties of C II], C III] and C IV line emitters through comparisons to the
LFs of H α and Ly α emitters, UV selected star-forming (SF) galaxies and quasars
at similar redshifts. The C II] LF at z ∼ 0.68 is equally well described by a
Schechter or a power-law LF, characteristic of a mixture of SF and AGN activity.
The C III] LF (z ∼ 1.05) is consistent to a scaled down version of the Schechter
H α and Ly α LF at their redshift, indicating a SF origin. In stark contrast,
the C IV LF at z ∼ 1.53 is well fit by a power-law, quasar-like LF. We find that
the brightest UV sources (MUV < −22) will universally have C III] and C IV emission.
However, on average, C III] and C IV are not as abundant as H α or Ly α emitters
at the same redshift, with cosmic average ratios of ∼0.02–0.06 to H α and ∼0.01–0.1
to intrinsic Ly α. We predict that the C III] and C IV lines can only be truly
competitive in confirming high-redshift candidates when the hosts are intrinsically
bright and the effective Ly α escape fraction is below 1 per cent. While C III]
and C IV were proposed as good tracers of young, relatively low-metallicity galaxies
typical of the early Universe, we find that, at least at z ∼ 1.5, C IV is exclusively
hosted by AGN/quasars, especially at large line equivalent widths.

text: We present spectroscopic follow-up of candidate luminous Ly α emitters (LAEs)
at z = 5.7–6.6 in the SA22 field with VLT/X-SHOOTER. We confirm two new luminous
LAEs at z = 5.676 (SR6) and z = 6.532 (VR7), and also present HST follow-up of
both sources. These sources have luminosities LLy α ≈ 3 × 1043 erg s−1, very high
rest-frame equivalent widths of EW0 ≳ 200 Å and narrow Ly α lines (200–340 km s−1).
VR7 is the most UV-luminous LAE at z > 6.5, with M1500 = −22.5, even brighter
in the UV than CR7. Besides Ly α, we do not detect any other rest-frame UV lines
in the spectra of SR6 and VR7, and argue that rest-frame UV lines are easier to
observe in bright galaxies with low Ly α equivalent widths. We confirm that Ly α
line widths increase with Ly α luminosity at z = 5.7, while there are indications
that Ly α lines of faint LAEs become broader at z = 6.6, potentially due to reionization.
We find a large spread of up to 3 dex in UV luminosity for >L⋆ LAEs, but find
that the Ly α luminosity of the brightest LAEs is strongly related to UV luminosity
at z = 6.6. Under basic assumptions, we find that several LAEs at z ≈ 6–7 have
Ly α escape fractions ≳ 100 per cent, indicating bursty star formation histories,
alternative Ly α production mechanisms, or dust attenuating Ly α emission differently
than UV emission. Finally, we present a method to compute ξion, the production
efficiency of ionizing photons, and find that LAEs at z ≈ 6–7 have high values
of log10(ξion/Hz erg−1) ≈ 25.51 ± 0.09 that may alleviate the need for high Lyman-Continuum
escape fractions required for reionization.

text: We present dynamical measurements from the KMOS (K-band multi-object spectrograph)
Deep Survey (KDS), which comprises 77 typical star-forming galaxies at z ≃ 3.5
in the mass range 9.0 < log (M⋆/M⊙) < 10.5. These measurements constrain the internal
dynamics, the intrinsic velocity dispersions (σint) and rotation velocities (VC)
of galaxies in the high-redshift Universe. The mean velocity dispersion of the
galaxies in our sample is σint=70.8+3.3−3.1kms−1, revealing that the increasing
average σint with increasing redshift, reported for z ≲ 2, continues out to z
≃ 3.5. Only 36 ± 8 per cent of our galaxies are rotation-dominated (VC/σint >
1), with the sample average VC/σint value much smaller than at lower redshift.
After carefully selecting comparable star-forming samples at multiple epochs,
we find that the rotation-dominated fraction evolves with redshift with a z−0.2
dependence. The rotation-dominated KDS galaxies show no clear offset from the
local rotation velocity–stellar mass (i.e. VC–M⋆) relation, although a smaller
fraction of the galaxies are on the relation due to the increase in the dispersion-dominated
fraction. These observations are consistent with a simple equilibrium model picture,
in which random motions are boosted in high-redshift galaxies by a combination
of the increasing gas fractions, accretion efficiency, specific star formation
rate and stellar feedback and which may provide significant pressure support against
gravity on the galactic disc scale.

text: Auxin steers numerous physiological processes in plants, making the tight
control of its endogenous levels and spatiotemporal distribution a necessity.
This regulation is achieved by different mechanisms, including auxin biosynthesis,
metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic
acid (c-CA) as a novel and unique addition to a small group of endogenous molecules
affecting in planta auxin concentrations. c-CA is the photo-isomerization product
of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing
medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes
characteristic for high auxin levels, including inhibition of primary root growth,
induction of root hairs, and promotion of adventitious and lateral rooting. By
molecular docking and receptor binding assays, we showed that c-CA itself is neither
an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not
significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation
assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux.
Auxin signaling reporters detected changes in spatiotemporal distribution of the
auxin response along the root of c-CA-treated plants, and long-distance auxin
transport assays showed no inhibition of rootward auxin transport. Overall, these
results suggest that the phenotypes of c-CA-treated plants are the consequence
of a local change in auxin accumulation, induced by the inhibition of auxin efflux.
This work reveals a novel mechanism how plants may regulate auxin levels and adds
a novel, naturally occurring molecule to the chemical toolbox for the studies
of auxin homeostasis.

text: 'We investigate fundamental nonlinear dynamics of ferrofluidic Taylor-Couette
flow - flow confined be-tween two concentric independently rotating cylinders
- consider small aspect ratio by solving the ferro-hydrodynamical equations, carrying
out systematic bifurcation analysis. Without magnetic field, we find steady flow
patterns, previously observed with a simple fluid, such as those containing normal
one- or two vortex cells, as well as anomalous one-cell and twin-cell flow states.
However, when a symmetry-breaking transverse magnetic field is present, all flow
states exhibit stimulated, finite two-fold mode. Various bifurcations between
steady and unsteady states can occur, corresponding to the transitions between
the two-cell and one-cell states. While unsteady, axially oscillating flow states
can arise, we also detect the emergence of new unsteady flow states. In particular,
we uncover two new states: one contains only the azimuthally oscillating solution
in the configuration of the twin-cell flow state, and an-other a rotating flow
state. Topologically, these flow states are a limit cycle and a quasiperiodic
solution on a two-torus, respectively. Emergence of new flow states in addition
to observed ones with classical fluid, indicates that richer but potentially more
controllable dynamics in ferrofluidic flows, as such flow states depend on the
external magnetic field.'

text: Coordinated changes of cell shape are often the result of the excitable, wave-like
dynamics of the actin cytoskeleton. New work shows that, in migrating cells, protrusion
waves arise from mechanochemical crosstalk between adhesion sites, membrane tension
and the actin protrusive machinery.

text: Selected universal experimental properties of high-temperature superconducting
(HTS) cuprates have been singled out in the last decade. One of the pivotal challenges
in this field is the designation of a consistent interpretation framework within
which we can describe quantitatively the universal features of those systems.
Here we analyze in a detailed manner the principal experimental data and compare
them quantitatively with the approach based on a single-band model of strongly
correlated electrons supplemented with strong antiferromagnetic (super)exchange
interaction (the so-called t−J−U model). The model rationale is provided by estimating
its microscopic parameters on the basis of the three-band approach for the Cu-O
plane. We use our original full Gutzwiller wave-function solution by going beyond
the renormalized mean-field theory (RMFT) in a systematic manner. Our approach
reproduces very well the observed hole doping (δ) dependence of the kinetic-energy
gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer
features of the cuprates. The calculated Fermi velocity in the nodal direction
is practically δ-independent and its universal value agrees very well with that
determined experimentally. Also, a weak doping dependence of the Fermi wave vector
leads to an almost constant value of the effective mass in a pure superconducting
phase which is both observed in experiment and reproduced within our approach.
An assessment of the currently used models (t−J, Hubbard) is carried out and the
results of the canonical RMFT as a zeroth-order solution are provided for comparison
to illustrate the necessity of the introduced higher-order contributions.

text: 'We investigate the effect of the electron-hole (e-h) symmetry breaking on
d-wave superconductivity induced by non-local effects of correlations in the generalized
Hubbard model. The symmetry breaking is introduced in a two-fold manner: by the
next-to-nearest neighbor hopping of electrons and by the charge-bond interaction
- the off-diagonal term of the Coulomb potential. Both terms lead to a pronounced
asymmetry of the superconducting order parameter. The next-to-nearest neighbor
hopping enhances superconductivity for h-doping, while diminishes it for e-doping.
The charge-bond interaction alone leads to the opposite effect and, additionally,
to the kinetic-energy gain upon condensation in the underdoped regime. With both
terms included, with similar amplitudes, the height of the superconducting dome
and the critical doping remain in favor of h-doping. The influence of the charge-bond
interaction on deviations from symmetry of the shape of the gap at the Fermi surface
in the momentum space is briefly discussed.'

text: Our understanding of stars through asteroseismic data analysis is limited
by our ability to take advantage of the huge amount of observed stars provided
by space missions such as CoRoT, Kepler , K2, and soon TESS and PLATO. Global
seismic pipelines provide global stellar parameters such as mass and radius using
the mean seismic parameters, as well as the effective temperature. These pipelines
are commonly used automatically on thousands of stars observed by K2 for 3 months
(and soon TESS for at least ∼ 1 month). However, pipelines are not immune from
misidentifying noise peaks and stellar oscillations. Therefore, new validation
techniques are required to assess the quality of these results. We present a new
metric called FliPer (Flicker in Power), which takes into account the average
variability at all measured time scales. The proper calibration of FliPer enables
us to obtain good estimations of global stellar parameters such as surface gravity
that are robust against the influence of noise peaks and hence are an excellent
way to find faults in asteroseismic pipelines.

text: Diffusions and related random walk procedures are of central importance in
many areas of machine learning, data analysis, and applied mathematics. Because
they spread mass agnostically at each step in an iterative manner, they can sometimes
spread mass “too aggressively,” thereby failing to find the “right” clusters.
We introduce a novel Capacity Releasing Diffusion (CRD) Process, which is both
faster and stays more local than the classical spectral diffusion process. As
an application, we use our CRD Process to develop an improved local algorithm
for graph clustering. Our local graph clustering method can find local clusters
in a model of clustering where one begins the CRD Process in a cluster whose vertices
are connected better internally than externally by an O(log2n) factor, where n
is the number of nodes in the cluster. Thus, our CRD Process is the first local
graph clustering algorithm that is not subject to the well-known quadratic Cheeger
barrier. Our result requires a certain smoothness condition, which we expect to
be an artifact of our analysis. Our empirical evaluation demonstrates improved
results, in particular for realistic social graphs where there are moderately
good—but not very good—clusters.
