Analysis of undulator radiation with an electromagnet undulator

引用

Chinese Physics C 2014年第7期38卷 135-138页

作者： vijay Huse Bramh Prakash G. mishra School of Physics DAVV Indore- 452001 (M. P.) India

In this paper we discuss the theory of undulator radiation in an electromagnet undulator. We discuss the spectral properties of undulator radiation when electrons are injected off the undulator axis. This paper highlights the distinctive features of the radiation spectrum from electromagnet undulators, as compared to PPM undulators.

Acute onset clozapine-induced hyperglycaemia: A case report

引用

General Psychiatry 2019年第2期32卷 95-96页

作者： Pradeep Kumar Dheerendra Kumar mishra Nimisha mishra Sunil Ahuja Gyanendra Raghuvanshi vijay Niranjan Department of Psychiatry Shyam Shah Medical College Rewa Rewa India Department of Psychiatry Mahatma Gandhi Memorial Medical College Indore India

Clozapine is an atypical antipsychotic which is described to have higher efficacy among all available antipsychotic medications. Clozapine is reserved especially for resistant schizophrenia due to its side effects. Clozapine-induced metabolic syndrome and hyperglycaemia are common longterm side effects and are responsible for increased mortality in patients with schizophrenia. In this case, a patient with resistant schizophrenia was presented with acute-onset hyperglycaemia and delirium with the use of clozapine within a week. Withdrawal of clozapine in the patient led to the improvement in delirium and hyperglycaemia without the use of any hypoglycaemic agent. This case s叩ports the notion that in certain cases clozapine can induce hyperglycemia through possible direct pathophysiological mechanisms within a shorter time frame.

CADASIL syndrome(cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy)presenting as psychosis

Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy(CADASIL) is the most common monogenic form of cerebral small-vessel disease characterised by recurrent strokes. Behavioural disturbance also presents in a significant proportion of subjects as neurotic spectrum disorders and psychotic features are rarely reported. In this case report, we highlight a 32-year-old man with CADASIL syndrome, who had overt psychotic symptoms with neurological signs later on.

Chaotic Encryption Scheme Using 1-D Chaotic Map

引用

International Journal of Communications, Network and System Sciences 2011年第7期4卷 452-455页

作者： Mina mishra vijay H. Mankar 不详

This paper proposes three different chaotic encryption methods using 1-D chaotic map known as Logistic map named as Logistic, NLFSR and Modified NLFSR according to the name of chaotic map and non-linear function involved in the scheme. The designed schemes have been crypt analyzed for five different methods for testing its strength. Cryptanalysis has been performed for various texts using various keys selected from domain of key space. Logistic and NLFSR methods are found to resist known plaintext attack for available first two characters of plaintext. Plaintext sensitivity of both methods is within small range along with medium key sensitivity. Identifiability for keys of first two of the scheme has not been derived concluding that methods may prove to be weak against brute-force attack. In the last modified scheme avalanche effect found to be improved compared to the previous ones and method is found to resist brute-force attack as it derives the conclusion for identifiability.
