A walk with my wife late in the morning
Innate immunity plays an important role in COVID19
I was excited as well as attracted by a couple of articles published in Science lately. They were regarding the function of type I interferon in the innate immunity. Genetic dysfunctions of type I interferon or the autoimmune mechanism against type I interferon predisposes severity in COVID19 infection as they say, even if they won't explain all of those severe cases. There must be multiple factors responsible for exacerbation of the cases.

It still seems to indicate the innate immunity plays an important role in defense mechanism for this virus infection. It has been noted those having had vaccination against pathogens other than this SARS CoV 2 may be resistant to the virus and/or may be spared from aggravation. Vaccination, including BCG, is known to augment the innate immunity.
The innate immunity could be affected by the past history of the host for viral or other pathogens' infection. It could be genetically polymorphic and may explain the fact that certain race is more resistant to it.
This finding that the innate immunity is of importance for defense against SARS CoV 2 may let us understand the pathophysiology of this infection and helps to find out the treatment based on it. It may help to distinguish those being aggravated in the course from the others in the beginning of the course as well.
I could not help being excited to know of such findings as these. Let's hope researchers may achieve understanding fully the process of the infection. It is the only way to solve this pandemic.

A fantasy early in a morning
Half an hour after our sunrise, I listened 20m and found W1AW sending Morse Code reception practice with pretty big signal. Otherwise, nothing else was heard. I tried to call CQ a bit below W1AW. No one has answered to me for 10 or 15 minutes. Calling CQ with the memory keyer and sometimes manually, I wondered what the CW world would undergo for the next 10 years.
Considering its history for the past decades, which I have lived in by myself, this trend of decline won't be changed. It has been discussed many times on this process. Despite of the efforts some groups are making to revert and augment its activity, this trend seems to continue. Whatever the reason of this decline might be, I believe, there would be much fewer CW operators, at least, those who could copy without decorder, in the next decade.
The average age of CW operators will be higher then. The only activity of CW might be contesting. Contests may last only for a day or even shorter considering of the age of the participants. There should be some net for just exchanging reports on certain frequency at some time in a day. Without these activities, the CW bands might sound quite silent. Some portion or all the bandwidth allotted for only CW might be shared with the digital modes. We might hear only screaming digital signals on those portion of the bands.
There could be hopefully a small number of CW operators who would enjoy the conversational CW. Those who find much fun in that communication style would hand down its tradition to the next generation. In the society that they could find easier way of communications, I believe, they should verbalize their fun in it and deliver it to the next generation. What they should pass on to the next generation is comprised of two aspects. As I have reiterated in this blog, one is regarding the joy of this communication itself. And the other is about the relationship with brass pounders all over the world. The former may be related with the the psychological process which could be depicted in brain-scientific term. In my view, in analogy with the pleasure in music, it could be a rewarding sensation associated with expectation for the up coming content of communication. I have written about it in a post. The latter is from the comrade with the this nerd enjoying this old fashioned communication mode all over the world. The relationships with them could be life long ones.
Well, having been indulged in this not very pleasant fantasy for the prospect of this mode, I got a few callers, all of them being good old friends of mine through this mode. I don't know if I am foreseeing it right or not. Empty CW bands seem to continue and even more empty in some time, I should say. Even though I could hear someone telling me I am too much a person of glass half empty.

A morning walk
It was another refreshing morning walk. I would return there from time to time.

Jean Guihen Queryas plays Unaccompanied Cello Suite Nr3
The unaccompanied cello suites by J.S.Bach has been deemed as the old testament in cello music. Technically, they are not so difficult to play just after the score as modern or romantic pieces for this instrument. The content is, however, profound and is like a mountain towering never conquered by climbers.
In its Prelude, I feel hearing the creation of the universe. Modern quantum theory tells there was a time when certain harmony was present immediately after the big bang of the universe creation process. Of course, it was not this suite itself which rang in the primitive universe. Something musical was present in the universe when it was born. This fact makes me touched a lot. And the spirit might be comparable to what we are impressed with this music.
Queryas is one of the best contemporary cellists. He plays this piece as if telling a story of creation. His concentration on the music is incredibly deep. There must be an effect of the reverberation in this recording. Together with it, his cello sings the song of creation with various nuances. Whenever I listen to his performance, I am lead to the world of creation. It is, in other words, a description of our inner world as well. Very fine texture and deep emotion.
Anner Bylsma, another great cellist recently passed away, used to tell we should play the unaccompanied suites as if telling stories. Queryas is a cellist who has realized his saying.
A long way to go for me to learn this piece.
This week end, I will have a chance to practice the cello sonata in e minor of Brahms with my niece at my sister's home. And a piece for soprano, cello and piano for a poem by Jukichi Yagi composed by a senior friend of mine in the medical school days. He has given that piece to me. It has been almost 20 years since I played it at a concert before the composer. I wish to play it again for him and other orchestra friends someday.

Chinese dumpling
I have cooked chinese dumpling yesterday. I am inclined to make it too much at one time. So did I yesterday. It tastes not bad but is still boring if we take it for 2 or 3 consecutive days.
