Abandoned Fishpond Reversal to Mangrove Forest: Will the Carbon Storage Potential Match the Natural Stand 30 Years after Reforestation?
carbon stock assessment carbon sequestration above and below ground carbon pools zonation
2023/12/4
Mangroves are essential carbon reserves, and their role in carbon sequestration is remarkable. However, anthropogenic pressures such as aquaculture development threatened this highly susceptible ecosy...
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2023/6/9
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
Earth's last magnetic field reversal took far longer than once thought（图）
Earth magnetic field reversal took longer once thought
2019/10/21
Earth's magnetic field seems steady and true -- reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes.The magnetic North Pole is currently shifting tow...
On the impossibility of entropy reversal, and its application to zero-knowledge proofs
statistical zero-knowledge proof entropy reversal black-box reduction
2017/9/25
Zero knowledge proof systems have been widely studied in cryptography. In the statistical setting, two classes of proof systems studied are Statistical Zero Knowledge (SZK) and Non-Interactive Statist...
Explicit Optimal Binary Pebbling for One-Way Hash Chain Reversal
hash chains pebbling in-place algorithms
2016/1/23
We present explicit optimal binary pebbling algorithms for reversing one-way hash chains. For a hash chain of length 2k , the number of hashes performed in each output round does not exceed dk/2e, ...
Time Reversal and Charge Conjugation in an Embedding Quantum Simulator
Charge Conjugation Embedding Quantum Simulator
2016/1/22
A quantum simulator is an important device that may soon outperform current classical computations. A basic arithmetic operation, the complex conjugate, however, is considered to be impossible to be i...
SRY-negative XX sex reversal in an English Cocker Spaniel: a case report
English Cocker Spaniel intersexuality SRY-negative
2015/5/25
A SRY-negative XX male describes a female karyotype with testicular tissue resulting from abnormal
gonadal development. In such cases male gonad formation takes place in the absence of a Y chromosom...

Testing Limits to Policy Reversal:Evidence from Indian Privatizations
Political Elections Privatization State Ownership India
2015/4/21
We examine the effect of regime change on privatization using the 2004 election surprise in India. The pro-reform BJP was unexpectedly defeated by a less reformist coalition. Stock prices of governmen...
Exploring the potentials and limitations of the time-reversal imaging of finite seismic sources
potentials time-reversal imaging
2014/12/31
The characterisation of seismic sources with timereversed wave fields is developing into a standard technique
that has already been successful in numerous applications.
Reversal of Severe Volume Deplete Acute Kidney Injury by Rasburicase
Acute Kidney Injury Rasburicase Hyperuricemia Ileostomy
2013/1/31
We report on a case of acute kidney injury in a patient with severe volume depletion from high ileostomy output and poor oral intake associated with hyperuricemia and hyperkalemia. The patient present...
The utilization of time reversal symmetry in designing and implementing (quantum) optical experiments has become more and more frequent over the past years. We review the basic idea underlying time re...
Spin current and polarization reversal through a single-molecule magnet with ferromagnetic electrodes
Spin current polarization reversal single-molecule magnet ferromagnetic electrodes
2012/2/27
We theoretically study the spin-polarized transport through a single-molecule magnet, which is weakly coupled to ferromagnetic leads, by means of the rate-equation approach. We consider both the ferro...
Cognition in response to the right-left reversal of visual and non-visual spatial information in the human nervous system
Cognitio response right-left reversal non-visual spatial information human nervous system
2016/3/16
Various research observations reported elsewhere are reviewed and interpreted here as they may be related in a process that is fundamental to the contralateral organization of the human nervous system...
Role Reversal in Global Finance
emerging markets international investment positions structure of external assets and liabilities foreign exchange reserves global liquidity insurance
2012/10/23
I document that emerging markets have cast off their "original sin" – their external liabilities are no longer dominated by foreign-currency debt and have instead shifted sharply towards direct invest...
