The High Mountain Asia glacier contribution to sea-level rise from 2000 to 2050

open access: yesAnnals of Glaciology, 2016
We estimate all the individual glacier area and volume changes in High Mountain Asia (HMA) by 2050 based on Randolph Glacier Inventory (RGI) version 4.0, using different methods of assessing sensitivity to summer temperatures driven by a regional climate

The Protestant Revolution or Wider die falsche Gelassenheit [PDF]

open access: yes, 2010
This contribution was prompted by events in East Germany that ultimately led to German unification. Many forces contributed to the collapse of the GDR as a separate state, the final and most visible was the mass exodus via Hungary and Czechoslovakia. The

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Multidecadal Trends in Large-Scale Annual Mean SATa Based on CMIP5 Historical Simulations and Future Projections

open access: yesEngineering, 2017
Based on observations and Coupled Model Intercomparison Project Phase 5 (CMIP5) results, multidecadal variations and trends in annual mean surface air temperature anomalies (SATa) at global, hemispheric, and hemispheric land and ocean scales in the past ...

Modified A-hypergeometric Systems

open access: yes, 2007
We will introduce a modified system of A-hypergeometric system (GKZ system) by applying a change of variables for Groebner deformations and study its Groebner basis and the indicial polynomials along the "exceptional hypersurface".Comment: 8 ...

Proof of Irreversibility for Systems with Time Reversal Symmetry

open access: yes, 2020
The positivity of entropy change rate was rigorously proven in a certain microscopic system associated with a Hamiltonian using only information about the microscopic system. This microscopic system obeys an equation with time-reversal symmetry.

Measurements of Nondegenerate Discrete Observables

open access: yes, 2000
Every measurement on a quantum system causes a state change from the system state just before the measurement to the system state just after the measurement conditional upon the outcome of measurement.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Health System Reform: The Value and Price of Innovation [PDF]

open access: yes, 2008
Explores the role of innovation in healthcare by reviewing the literature on international, federal, state, and local examples of system change; barriers to change; the contributions of research, academia, and industry; and the financing of ...
