• #### Keep up or drown: adjustment of western Pacific coral reefs to sea-level rise in the 21st century ﻿

(2015-07-22)
Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for ...
• #### Keeping up with sea-level rise: Carbonate production rates in Palau and Yap, western Pacific Ocean ﻿

(2018-05-08)
Coral reefs protect islands from tropical storm waves and provide goods and services for millions of islanders worldwide. Yet it is unknown how coral reefs in general, and carbonate production in particular, will respond ...
• #### KEPLER 453 b - THE 10th KEPLER TRANSITING CIRCUMBINARY PLANET ﻿

(2015-08-10)
We present the discovery of Kepler-453 b, a 6.2 RƟ planet in a low-eccentricity, 240.5 day orbit about an eclipsing binary. The binary itself consists of a 0.94 and 0.195 M☉ pair of stars with an orbital period of 27.32 ...
• #### Kepler eclipsing binary stars. VII. The catalog of eclipsing binaries found in the entire Kepler data set ﻿

(2016-03)
The primary Kepler Mission provided nearly continuous monitoring of ∼200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary systems within the 105 deg2 Kepler field ...
• #### The Kepler Light Curve of V344 Lyrae: Constraining the Thermal-viscous Limit Cycle Instability ﻿

(2010-11-29)
We present time-dependent modeling based on the accretion disk limit cycle model for a 270 d light curve of the short-period SU UMa-type dwarf nova V344 Lyr taken by Kepler. The unprecedented precision and cadence (1 minute) ...
• #### The Kepler Light Curves of V1504 Cygni and V344 Lyrae: A Study of the Outburst Properties ﻿

(2012-02-23)
We examine the Kepler light curves of V1504 Cyg and V344 Lyr, encompassing ~736 days at one-minute cadence. During this span each system exhibited ~64–65 outbursts, including 6 superoutbursts. We find that, in both systems, ...
• #### KOI-3158: The oldest known system of terrestrial-size planets ﻿

(2015-09-23)
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form ...

(2015-09-23)
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form ...
• #### The Kolmogorov equation with time-measurable coefficients ﻿

(2003-07-13)
Using both probabilistic and classical analytic techniques, we investigate the parabolic Kolmogorov equation  L_t v +\frac {\partial v}{\partial t}\equiv \frac 12 a^{ij}(t)v_{x^ix^j} +b^i(t) v_{x^i} -c(t) v+ f(t) ...
• #### Lactose variability of Escherichia coli in thermally stressed reactor effluent waters ﻿

(1978)
Lactose-utilizing and nalidixic acid-resistant populations of Escherichia coli, having an optimum growth temperature of 37°C, were placed in modified diffusion chambers. The chambers were submerged in the epilimnion and ...
• #### Lajos Takács and his work ﻿

(1994-10-01)
This paper, written in honor of the 70th birthday of Lajos Takács, addresses his life and work, and includes some personal observations and appreciation of his contributions. In particular, it includes a short biography, ...
• #### Layered analytical radiative transfer model for simulating water color of coastal waters and algorithm development ﻿

(2000-12-22)
A remote sensing reflectance model, which describes the transfer of irradiant light within a homogeneous water column has previously been used to simulate the nadir viewing reflectance just above or below the water surface ...
• #### Layered unequal loss protection for image transmission over packet loss channels with delay constraints ﻿

(2004-10-25)
In the case of high bit rate image transmission or having lots of packets, the FEC (forward error correction) encoding and decoding processes in the ULP (unequal loss protection) based schemes should be applied to individual ...
• #### Layered unequal loss protection for progressive image transmission over packet loss channels ﻿

(2004-01-18)
In the past, many schemes have been proposed for progressive image transmission using unequal error protection (UEP) or unequal loss protection (ULP). However, most existing UEP/ULP schemes do not consider the minimum image ...
• #### The lightning-TGF relationship on microsecond timescales ﻿

(2011-07-28)
We analyze the count rates of two terrestrial gamma-ray flashes (TGFs) detected by the Fermi Gamma-ray Burst Monitor (GBM) with the broadband magnetic fields (1 to 300 kHz) produced by the simultaneous lightning processes. ...
• #### Limits on spacetime foam ﻿

(2011-04-04)
Plausibly spacetime is foamy on small distance scales, due to quantum fluctuations. We elaborate on the proposal to detect spacetime foam by looking for seeing disks in the images of distant quasars and active galactic ...
• #### Line detection using Wavelet filters ﻿

(2003-09-25)
We proposed a new line detection method in noisy images using Mexican hat wavelet filters. In our approach, we applied the wavelet transform in a multiresolution sense by forming the products of wavelet coefficients at the ...
