Shifts in Forest Species Composition and Abundance under Climate Change Scenarios in Southern Carpathian Romanian Temperate Forests
LANDIS-II PnET climate change Southern Carpathians forest biomass production species composition species abundance Romanian temperate forests
2023/12/11
The structure and functioning of temperate forests are shifting due to changes in climate. Foreseeing the trajectory of such changes is critical to implementing adequate management practices and defin...
Shifts in Foliage Biomass and Its Vertical Distribution in Response to Operational Nitrogen Fertilization of Douglas-Fir in Western Oregon
Douglas-fir nitrogen fertilization foliage distribution allometry biomass
2024/2/4
Nitrogen (N) fertilization is a commonly applied silvicultural treatment in intensively managed coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantations. Field trials were e...
Constructing APN functions through isotopic shifts
Boolean function APN isotopic equivalence
2018/8/28
Almost perfect nonlinear (APN) functions over fields of characteristic 2 play an important role in cryptography, coding theory and, more generally, information theory as well as mathematics. Building ...
Musical literacy shifts asymmetries in the ventral visual cortex
Hemispheric specialization Lateralization Music notation
2017/8/25
The acquisition of literacy has a profound impact on the functional specialization and lateralization of the visual cortex. Due to the overall lateralization of the language network, specialization fo...
Accounting for rate-dependent category boundary shifts in speech perception
Speech rate Rate-dependent perception Rate normalization
2017/8/25
The perception of temporal contrasts in speech is known to be influenced by the speech rate in the surrounding context. This rate-dependent perception is suggested to involve general auditory processe...
Quantum-Secure Symmetric-Key Cryptography Based on Hidden Shifts
secret-key cryptography quantum-security
2016/12/8
Recent results of Kaplan et al., building on previous work by Kuwakado and Morii, have shown that a wide variety of classically-secure symmetric-key cryptosystems are completely broken when exposed to...
Testability and Epistemic Shifts in Modern Cosmology
cosmology multiverse theory evaluation testability falsifiability demarcation criteria Popper
2016/5/30
During the last decade new developments in theoretical and speculative cosmology have reopened the old discussion of cosmology’s scientific status and the more general question of the demarcation betw...
Solvent-Induced Infrared Frequency Shifts in Aromatic Nitriles are Quantitatively Described by the Vibrational Stark Effect
Nitriles Spectroscopy,Fourier Transform Infrared Vibration Static Electricity Solvents
2016/5/25
The physical properties of solvents strongly affect the spectra of dissolved solutes, and this phenomenon can be exploited to gain insight into the solvent-solute interaction. The large solvatochromic...
Decomposition of Vibrational Shifts of Nitriles into Electrostatic and Hydrogen-Bonding Effects
Pseudomonas putida Nitriles Steroid Isomerases Spectrophotometry, Infrared Magnetic Resonance Spectroscopy Catalytic Domain Hydrogen Bonding Vibration Static Electricity
2016/5/25
Infrared (IR) band shifts of isolated vibrational transitions can serve as quantitative and directional probes of local electrostatic fields, due to the vibrational Stark effect. However, departures f...
On the Origin of Heme Absorption Band Shifts and Associated Protein Structural Relaxation in Myoglobin Following Flash Photolysis
transhydrogenase NAD NADP Escherichia coli proton pump metal ion
2016/5/23
The role of the protein structural change monitored by absorption band shifts following flash photolysis of CO from myoglobin is discussed in terms of structure-function relationships. Evidence is pre...
