Science Behind Paranormal Activities
This detail explanation is about the scientific causes behind every paranormal incident. Now-a-days documentary films on paranormal activities or researches on paranormal incidents is spreading throughout the world. But none of the researcher shows the exact cause behind those incidents. Scientists or the host of any paranormal tv shows directly said those canrsquot be explained. Yes, thatrsquos true but not completely. They should say those canrsquot be explained by normal scientific explanations. Thatrsquos why it is called lsquoParanormalrsquo. In this paper, Irsquom going to unveil the real cause behind every paranormal incident with logics and scientific explanations. People should be reminded that all those concepts of physics and metaphysics are based on assumption. All those prove has been done on the basis of several assumptions
Next to leading order non Fermi liquid corrections to the neutrino emissivity and cooling of the neutron star
In this work we derive the expressions of the neutrino mean free path(MFP)
and emissivity with non Fermi liquid corrections up to next to leading
order(NLO) in degenerate quark matter. The calculation has been performed both
for the absorption and scattering processes. Subsequently the role of these NLO
corrections on the cooling of the neutron star has been demonstrated. The
cooling curve shows moderate enhancement compared to the leading order(LO)
non-Fermi liquid result. Although the overall correction to the MFP and
emissivity are larger compared to the free Fermi gas, the cooling behavior does
not alter significantly.Comment: 8 pages, 8 figures, references added, matches published versio
On the Stability of Coherent States for Pais-Uhlenbeck Oscillator
We have constructed coherent states for the higher derivative Pais-Uhlenbeck
Oscillator. In the process we have suggested a novel way to construct coherent
states for the oscillator having only negative energy levels. These coherent
states have negative energies in general but their coordinate and momentum
expectation values and dispersions behave in an identical manner as that of
normal (positive energy) oscillator. The coherent states for the Pais-Uhlenbeck
Oscillator have constant dispersions and a modified Heisenberg Uncertainty
Relation. Moreover, under reasonable assumptions on parameters these coherent
states can have positive energies.Comment: Title changed, modified version with no major change in results and

Full Paper: Neural Text Generators in Enterprise Modeling: Can Chatgpt be Used as Proxy Domain Expert?
Enterprise modeling is concerned with the systematic development of a comprehensive and holistic representation of an enterprise (an enterprise model) to support organisational initiatives. Domain experts have an essential role in enterprise modeling projects (EM), as they provide the required domain knowledge or specifics of the organisation under consideration. The paper investigates if neural text generators (large language models) can reduce the dependency on domain experts for certain tasks in enterprise modeling. The main contributions of this paper are (1) a systematic literature analysis on neural text generator use in EM, (2) the identification of potential for applying large language models in EM, and (3) findings from quasi-experiments comparing output of ChatGPT and domain experts for the same EM task
An actor based simulation driven digital twin for analyzing complex business systems
Modern enterprises aim to achieve their business goals while operating in a competitive and dynamic environment. This requires that these enterprises need be efficient, adaptive and amenable for continuous transformation. However, identifying effective control measures, adaptation choices and transformation options for a specific enterprise goal is often both a challenging and expensive task for most of the complex enterprises. The construction of a high-fidelity digital-twin to evaluate the efficacy of a range of control measures, adaptation choices and transformation options is considered to be a cost effective approach for engineering disciplines. This paper presents a novel approach to analogously utilise the concept of digital twin in controlling and adapting large complex business enterprises, and demonstrates its efficacy using a set of adaptation scenarios of a large university
The holographic spectral function in non-equilibrium states
We develop holographic prescriptions for obtaining spectral functions in
non-equilibrium states and space-time dependent non-equilibrium shifts in the
energy and spin of quasi-particle like excitations. We reproduce strongly
coupled versions of aspects of non-equilibrium dynamics of Fermi surfaces in
Landau's Fermi-liquid theory. We find that the incoming wave boundary condition
at the horizon does not suffice to obtain a well-defined perturbative expansion
for non-equilibrium observables. Our prescription, based on analysis of
regularity at the horizon, allows such a perturbative expansion to be achieved
nevertheless and can be precisely formulated in a universal manner independent
of the non-equilibrium state, provided the state thermalizes. We also find that
the non-equilibrium spectral function furnishes information about the
relaxation modes of the system. Along the way, we argue that in a typical
non-supersymmetric theory with a gravity dual, there may exist a window of
temperature and chemical potential at large N, in which a generic
non-equilibrium state can be characterized by just a finitely few operators
with low scaling dimensions, even far away from the hydrodynamic limit.Comment: revtex; 43 pages, 2 figures; typos corrected, accepted for

Isolation and characterization of acid and base degradation products in Atenolol and Hydrochlorothiazide and a validated selective stability-indicating HPLCUV method for their quantification
Atenolol (( RS )-2-{4-[2-Hydroxy-3-(propan-2-ylamino)propoxy]phenyl}acetamide) and Hydrochlorothiazide (6-chloro-1,1-dioxo-3,4-dihydro-2 H -1,2,4-benzothiadiazine-7-sulfonamide) are beta 1 (? 1 ) receptor blocker and diuretic drug respectively; however the combination dosage regime are used for cardiovascular therapy. Thus a forced degradation study was carried out upon this combination drug regime under acidic and basic environment in order to deconvolute the possible degradation product under specified stressed conditions. Under acidic conditions atenolol and hydrochlorothiazide were cleaved into 2-(4-(3-amino-2- oxopropoxy) phenyl) acetamide and 6-sulphamido benzothiazide. However, under basic conditions, the drugs were spliced into 2-(4-(2-hydroxypropoxy) phenyl) acetamide and 2-chloro 4-amino 1, 6-dihydro benzene sulphonamide respectively. The degradant peaks were elucidated by HPLC using C18 column with methanol: phosphate buffer (70:30 v/v) with a flow rate of 0.5ml/min (UV detection at 226nm). For quantitative method validation, linearity was observed over product concentration range 2g/ml - 100 g/ml (r 2 0.9992) with regression equation y=43432x. The products were first identified by LC-MS and further confirmed by FT-IR and 1 H 1 NMR. A specific and sensitive stability-indicating assay method for the simultaneous determination of the drugs, its process related impurities and degradation products was developed
