Hawking radiation as tunneling and the unified first law of thermodynamics at the apparent horizon in the FRW universe

, 2009
Relations between the tunneling rate and the unified first law of thermodynamics at the apparent horizon of the FRW universe are investigated. The tunneling rate arises as a consequence of the unified first law of thermodynamics in such a dynamical ...

Unified first law and some general prescription: a redefinition of surface gravity

, 2017
The paper contains an extensive study of the unified first law (UFL) in the Friedmann-Robertson-Walker spacetime model. By projecting the UFL along the Kodama vector the second Friedmann equation can be obtained.

Transcriptome response comparison between vector and non-vector aphids after feeding on virus-infected wheat plants

BMC Genomics, 2020
Background Plant viruses maintain intricate interactions with their vector and non-vector insects and can impact the fitness of insects. However, the details of their molecular and cellular mechanisms have not been studied well.

Flow Resistance and Hydraulic Geometry in Gravel‐And Boulder‐Bed Rivers

Water Resources Research, Volume 61, Issue 3, March 2025.
Abstract The frictional resistance of river beds affects how water discharge is partitioned between depth and velocity, which is important in many aspects of hydrology, geomorphology, and aquatic ecology. Many of the most widely‐used resistance equations predict reach‐average velocity from relative submergence (RS), the ratio of mean flow depth to a ...

A búza törpülés vírus (Wheat dwarf virus) etiológiai vizsgálata és molekuláris jellemzése. = Etiology and molecular characterization of Wheat dwarf virus. [PDF]

, 2011
A kutatások keretében az ország különböző helyeiről gyűjtöttünk vírusizolátumokat Átviteli kísérleteink során a WDV 11 nappal a kabócával történt inokuláció után már kimutatható volt a növényből, a víruskoncentráció 4-5 hétig emelkedett, majd csökkent.

Small Non-Coding RNAs in the Regulatory Network of Wheat Dwarf Virus-Infected Wheat

Agriculture
Wheat dwarf virus (WDV) is a major constraint to global wheat production, causing severe yield losses and economic disruption. Understanding the molecular basis of wheat–WDV interactions is essential for developing resistant cultivars.

Thermodynamics of Lemaitre-Tolman-Bondi Model

, 2010
Here we consider our universe as inhomogeneous spherically symmetric Lemaitre-Tolman-Bondi Model and analyze the thermodynamics of this model of the universe. The trapping horizon is calculated and is found to coincide with the apparent horizon.

Breeding for resistance to insect-transmitted viruses in barley – an emerging challenge due to global warming

Journal für Kulturpflanzen, 2009
Due to global warming longer periods of higher temperature in autumn and winter are expected which may result in an increasing importance of insect-transmitted viruses.

Presence and Impact of Adverse Childhood Experiences and Reflective Functioning on Aggression in Adults With Antisocial Behaviour

Clinical Psychology &Psychotherapy, Volume 31, Issue 6, November/December 2024.
ABSTRACT This cross‐sectional study investigated the relationship between the presence and impact of ACEs with both reactive and proactive aggression, and the possible moderating role of mentalization (operationalized as reflective functioning) in these expected relationships.
