Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector.

Viral vectors are tools commonly used by molecular biologists to deliver genetic material into cells.

Viruses have evolved?

specialized molecular mechanisms

to efficiently

transport their genomes

inside the cells they infect.

Delivery of genes, or other genetic material, by a vector is termed transduction and the infected cells are described as transduced.

A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another.

Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).

The process of converting one form of energy to another is known as transduction.

active sensors, in contrast, generate an electric current in response to an external stimulus which serves as the output signal without the need of an additional energy source. Such examples are a photodiode, and a piezoelectric sensor, thermocouple.

Piezoelectric crystals – converts deformations of solid-state crystals (vibrations) to and from electrical signals

Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress.

In some cases, almost 100% of the light energy can be converted to the second harmonic frequency. These cases typically involve intense pulsed laser beams passing through large crystals, and careful alignment to obtain phase matching.

During a normal pregnancy, oxidative stress enhances antioxidant mechanisms that are capable of reacting by way of enzyme activity and non-enzyme free radical deactivators. However, pregnancy is also a state in which this adaptation and balance may be easily disrupted.

There is strong evidence that a chronicin flammatory reaction combined with the presence of a local oxidizing environment may play a vital role in the etiology and development of complications during pregnancy.

In late pregnancy, damage to DNA (especially when it is caused by oxidative stress) is associated with pre-eclampsia(PE), intrauterine growth restriction (IUGR), and the death of mothers in developing countries; it largely determines pregnancy – related susceptibility to diseases

The referential values of ROS and NOS and their minimal and safe concentrations or physiologically beneficial concentrations are yet to be determined.

The measurement of oxidative stress in vivo is perceived as controversial,

as the sen-sitivity and specificity of various oxidative stress markers is unknown.. .

This nonspecific cation channel opens when illuminated with blue light, depolarizing the cell [4, 6] to trigger action potentials cells with high temporal precision [5]. Since the initial discovery of ChR2, many modifications have been made to refine the kinetic properties.

For example, ChETA, engineered to address limitations of spike fidelity with ChR2, has faster temporal kinetics and can maintain reliable spike precision up to 200 Hz [7].

Halorhodopsins (NpHR), light-gated chloride pumps activated by yellow light, allow for temporally specific hyperpolarization with single spike precision [8–10].

Archaerhodopsin-3 (Arch), a yellow light-activated outward proton pump, is an increasingly popular tool for light-induced hyperpolarization to inhibit cellular activity. Arch recovers spontaneously from inactivation with a much shorter recovery time than NpHRs [11].

Arch currents continue to increase with increasing light intensity, while NpHRs saturate [11]. The increased light sensitivity of the ArchT variant, along with better membrane targeting, allows for improved neural silencing both at cell bodies and terminals [12].

No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.

👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em

The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)

Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)

Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)

In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

NEW—CDC was truly suffocated by Trump WH at every turn. Kyle McGowan, a former chief of staff at CDC, and his deputy, Amanda Campbell, witnessed WH dismissal of science, WH’s slow suffocation of CDC’s voice, meddling in messages & siphoning of CDC budget.

2) ““Everyone wants to describe the day that the light switch flipped—It didn’t happen that way—more of like a hand grasping something, and it slowly closes, closes, closes, closes until you realize that, middle of the summer, it has a complete grasp on everything at the CDC”

3) “Mr. McGowan and Ms. Campbell, both 34, say they tried to protect their colleagues against political meddling from WH and HHS but was largely stifled by the Trump administration.

4) “The White House insisted on reviewing — and often softening — the C.D.C.’s closely guarded coronavirus guidance documents, the most prominent public expression of its latest research and scientific consensus on the spread of the virus.”

5) “The documents were vetted not only by the White House’s coronavirus task force but by what felt to the agency’s employees like an endless loop of political appointees across Washington.
Mr. McGowan recalled a White House fixated on the economic implications of public health.

A week ago I voluntarily admitted myself to the hospital to get help bc I am losing weight as a result of increased food intolerances, secondary to my very severe #MECFS. A psychiatrist here decided that im mentally ill, 1/

purely on the basis that the medical workup was unable to explain my food intolerance. My psych eval only found mild anxiety and depression. 2/

They have put me on a 72hr psych hold while they work to get the county courts to commit me to a psych ward. This is a nightmare. They have taken away most of my belongings, put me in a new uniform, and are keeping me under 24/7 video surveillance. 3/

In the middle of the night last night when I sat up to use the urinal loud alarms sounded, as though I was trying to escape. I can’t even walk and hadn’t even left my bed. 4/

If they succeed in having me fully committed I will lose ability to communicate with the outside world except for an occasional phone call. I will lose all agency, and will very likely have treatments forced upon me. 5/

Let’s talk about ORGANIC.

Robert Paarlberg’s new book on the food system is out today, and here’s an excerpt.

He’s not a fan of organic, and he makes some good points but misses others.

Here we go.

Organic's biggest shortcoming is that you need more land to grow the same amount of food.

The yield penalty happens in almost every crop, in almost every study.

The gap could narrow with more research/varieties, but it won’t go away.

This has big, bad climate implications.

The second issue I have with organic, which Paarlberg shares, is that its basic criterion is naturalness.

Natural doesn’t mean safe, or even safer. A farming standard based on it forces farmers to sometimes use more dangerous, less effective tools.

On human health, there’s scant evidence that pesticide residues on conventional produce are harmful to consumers (though it’s possible farmworkers could be at risk).

What I don’t want is for folks who can’t afford organic to worry about feeding their kids conventional produce.

On the plus side, Paarlberg acknowledges that the organic standard has some real advantages for animal welfare.

This is why I buy organic animal products.

Many in the organic world would like more regs ensuring animals have decent lives.

Singing the Blues:
Taking Down an Insider Threat

"I had all of the advantages. I was already inside the network. No one suspected me. But they found my hack, kicked me off the network...

...and physically hunted me down."

Many pentests start from the outside, wanting to see how the perimeter might be breached.

This pentest started from the inside. My client wanted to assume they had already been breached, and, if breached, how far could an attacker go.

Could they stop me once I was inside?

So they snuck me in. Disguised me as a new employee. Gave me a work computer, an ID badge, an account in their system... hell, I even had a cubicle w/my assumed name on it.

The only person who knew who I really was was their CISO. Everyone else thought I was Jeremy in Marketing.

During most of the first morning, I completed onboarding, made introductions, and completed menial tasks.

But I had to act quick. I only had a week onsite. I had to hack their network while not raising suspicion.

So I set about it.

You have to understand... most "Internal Pentests" are straight forward. The hard part is breaching the network, but once you're inside, it's a target rich environment. End of Life computers, default passwords, everyone a Local Administrator...

Some ofthe biggest breakouts occur after Volatility Contraction, the analogy is that more a spring is pressed, higher it jumps whenever it gets released.

There is a VCP Scanner on chartink (Not mine). This may also be used to find potential Breakouts.

Glorious Vedic Architecture and Temple

Architecture in India was an extremely rich form of expression and highly developed science, with a deep heritage of spirituality in it. #FreeHinduTemple

The centre of all architectural development was the temple and temple or Mandir was the earthly home of God, and like the launching pad for the devotee’s consciousness to soar toward the Divine and the spiritual world.

The murti or deity of the Divine would be placed in the temple sanctum, around which all temple activity would revolve.

Such buildings were often elaborately decorated with stone, wood, plaster, etc. and carved or cut to depict the stories from the Puranas or other sacred texts

Temples were always the centre of religious, social and educational activities, practically more so in
ancient times than today.

During a span of more than two thousand years, various dynasties were known for constructing glorious temples,

some of which include the Mauryan, Ashoka, Gupta, Satavahana, Chedi, Chandella, Chalukya, Solanki, Pallava, Shola, Hoysala, Vijayanagar, and others.

Many of these temples remain beautiful architectural wonders today.
