Study of fragmentation and momentum correlations in heavy-ion collisions
The role of momentum correlations is studied in the production of light and
medium mass fragments by imposing momentum cut in clusterization the phase
space. Our detailed investigation shows that momentum cut has major role to
play in the emission of fragments.Comment: 16 pages, 7 figure
2-(2-Bromophenyl)acetic acid
In the title molecule, C8H7BrO2, the carboxyl group is twisted by 76.2 (3)° from the benzene ring plane. In the crystal, molecules are linked into inversion dimers through pairs of O—H⋯O hydrogen bonds. The dimers are further linked into layers parallel to the bc plane by weak C—H⋯O hydrogen bonds

3-Anilinothiocarbonyl-4-hydroxychromen-2-one
The geometrical parameters of the title compound, C16H11NO3S, are in the usual ranges. The two aromatic residues are not coplanar and are twisted by a dihedral angle of 66.63 (6)°. The crystal structure is stabilized by N—H⋯O and O—H⋯S interactions
Effectiveness analysis of antipsychotics in schizophrenia using psychometric scales: an observational study
Background: Schizophrenia is a commonest and one of the well known psychiatric disorders. Life expectancy of a patient with schizophrenia may be 20 to 30 years shorter than the general population. Long term antipsychotic therapy is usually required for the management of schizophrenia. It is not currently possible to predict which antipsychotic may be optimal for a given patient because there are still many debates about effectiveness and efficacy of atypical drugs over first generation antipsychotics. So, our aim is to assess the effectiveness of various antipsychotics by using various psychometric scales, which will be helpful to bring out better treatment options for schizophrenia patients.Methods: This was an observational questionnaire based study, conducted on patients of inpatient and outpatient Department of Psychiatry and Department of Pharmacology at VIMSAR, Burla, for a period of 24 months (September 2015 to August 2017). Patients of schizophrenia aged 18 years or above were subjected to clinical global impression – severity scale (CGI-S) and clinical global impression – improvement scale (CGI-I) questionnaire after taking informed consent. Then scores were calculated using non parametric test with Graph pad Prism version 6.0.Results: Out of the 90 cases, majority (60) of patients belonged to the middle (25 to 45 yrs) age group followed by 20 younger (45 yrs) patients. Both scales showed significant improvement with atypical antipsychotics as compared to first generation antipsychotics.Conclusions: Based on these findings, we can conclude that atypical antipsychotics are more effective than first generation antipsychotics. But further studies are needed to assist clinicians in making optimum treatment decisions
2-(2-Chlorophenyl)acetic acid
In the title compound, C8H7ClO2, the carboxyl group forms a dihedral angle of 74.83 (9)° with the benzene ring plane. In the crystal, molecules are linked into inversion dimers by pairs of O—H⋯O hydrogen bonds. The dimers are linked into layers parallel to the bc plane by weak C—H⋯O interactions
Market Power Mitigation in Two-stage Electricity Market with Supply Function and Quantity Bidding
The main goal of a sequential two-stage electricity market -- e.g., day-ahead
and real-time markets -- is to operate efficiently. However, the price
difference across stages due to inadequate competition and unforeseen
circumstances leads to undesirable price manipulation. To mitigate this, some
Independent System Operators (ISOs) proposed system-level market power
mitigation (MPM) policies in addition to existing local policies. These
policies aim to substitute noncompetitive bids with a default bid based on
estimated generator costs. However, these policies may lead to unintended
consequences when implemented without accounting for the conflicting interest
of participants. In this paper, we model the competition between generators
(bidding supply functions) and loads (bidding quantity) in a two-stage market
with a stage-wise MPM policy. An equilibrium analysis shows that a real-time
MPM policy leads to equilibrium loss, meaning no stable market outcome (Nash
equilibrium) exists. A day-ahead MPM policy, besides, leads to a
Stackelberg-Nash game with loads acting as leaders and generators as followers.
In this setting, loads become winners, i.e., their aggregate payment is always
less than competitive payments. Moreover, comparison with standard market
equilibrium highlights that markets are better off without such policies.
Finally, numerical studies highlight the impact of heterogeneity and load size
on market equilibrium
