Die Galerie in der Peterstraße Curating, Design, Production

Lisa Pappon and I opened a gallery in Peterstraße in 2016. The goal was simple: younger artists, classical media, weird energy. We kept it going into 2017. Sold some work. Made some shows we were proud of. Then we moved on.

Here are a few of them.

— Jonas Hinnerkort SAVE

Jonas formed his works within self-asserted systems. Most of the pieces were essentially drawings, using lines as markers of direction or movement. The central work featured black boards with silkscreened circles, each filled with colored chalk lines. They were mounted with magnets on a wooden frame, allowing the end user to determine the layout. I really responded to the modularity of the piece.

The circle reappeared in a wall sculpture, positioned to draw focus as you entered the gallery. A high-gloss black disc, its shape seemed hand-drawn: all shine, soft curves, hand-made energy.

— Dominique Bernadet, Katharina Langer, Karl Heinz Maukel Von der Insel auf das Festland

Katharina Langer, Karl Heinz Maukel, and Dominique Bernadet came to us through Honigfabrik in Wilhelmsburg. We responded to the eclectic energy of their work. Dominique showed bronze pieces that questioned the formal history of the medium. Katharina pushed realist and romanticist painting into the twenty-first century (only later did I realise her work could basically be called neo-formalist).

Karl Heinz combined the language of constructivist sculpture with found objects, adding geometric abstractions layered with video projections. We lit the gallery in subdued spotlights, partly to create an intimate chamber-like atmosphere, but also because Karl Heinz needed darkness for the projections. The result worked.

— Chuang Yi-Jou WEG/STRECKE

Yi-Jou works in stage design, but her roots in painting run deep. One could call her works neo-impressionist, but they were so much more than that. She would take images seen while traveling, transpose them onto the surfaces of 3D cubes, then paint the cubes on canvas. The humour of moving from 3D to 2D, with a wink and so much character, still makes me chuckle.

She also performed twice at the gallery during the Drunter & Drüber – Neustadt Festival: WEG/STRECKE and 2.5D Cube. In WEG/STRECKE, she danced over a paper runner, with movement sensors hidden under her costume. The sensors were wired to a small robot, which responded to her movement by drawing lines across the paper. Sick.

Performed by: Chuang Yi-Jou Costume design: Isabel Wiethölter

In 2.5D Cube, she acted as the third dimension of a drawn cube spanning the gallery floor and two walls. Sick x 2(.5).

Performed by: Chuang Yi-Jou Costume design: Kai-Chiang Lin

— Ivan Šuletić Gebäude und Pflanzen

Ivan works at the intersection of classical landscape painting and contemporary visual language. He creates massive cityscapes and landscapes, often by repeating a single detail until the canvas is filled, across formats as large as 200 × 240 cm.

His smaller ink works follow a similar logic, producing pieces that feel almost inhuman (superhuman?) in their precision. Classical training meets glitch sensibility, with a nod to post-internet aesthetics. Viewers often assumed the works were digitally produced, but every line was made by hand.

When I grow up, I’ll treat myself to a Šuletić original.

Beyond Snoring: How Are MADs Revolutionizing Sleep Apnea Treatment?

Why Are Mandibular Advancement Devices Crucial for Sleep Disorders?

Mandibular Advancement Devices (MADs) are a class of oral appliances used primarily in the treatment of snoring and mild to moderate obstructive sleep apnea (OSA). These devices work by repositioning the lower jaw (mandible) and tongue forward, thereby increasing the patency of the upper airway during sleep and preventing its collapse. Unlike Continuous Positive Airway Pressure (CPAP) machines, which can be bulky and sometimes uncomfortable for patients, MADs offer a less invasive and often more convenient alternative. Their importance stems from their ability to significantly improve sleep quality, reduce the symptoms of sleep apnea (such as snoring, excessive daytime sleepiness), and mitigate associated health risks like cardiovascular issues. As awareness of sleep disorders grows, so does the demand for effective and patient-friendly solutions like MADs.

What Technological Advancements Are Shaping MAD Design and Efficacy?

The field of Mandibular Advancement Devices is witnessing continuous technological advancements, primarily focused on enhancing patient comfort, customization, and therapeutic efficacy.

A major innovation is the widespread adoption of 3D scanning and printing technologies in MAD fabrication. This digital workflow allows for the creation of highly customized and comfortable devices tailored precisely to a patient's unique jaw structure and dental anatomy. Traditional MADs often involved multiple physical impressions and adjustments, which could be cumbersome. With 3D scanning, a digital impression of the patient's mouth is taken, and then the MAD is designed using CAD (Computer-Aided Design) software before being precisely manufactured with 3D printing. This not only improves the fit and comfort, leading to higher patient compliance, but also streamlines the manufacturing process, potentially reducing production time and costs.

Beyond custom fit, manufacturers are integrating smart technology into MADs. This includes the incorporation of sensors that monitor sleep patterns and jaw position throughout the night. These sensors can provide valuable data to both patients and clinicians, allowing for objective assessment of treatment effectiveness. For example, some devices can track jaw advancement, identify specific sleep positions that exacerbate apnea, or even offer real-time feedback. This data can help optimize the device's settings and improve overall patient experience and therapeutic outcomes.

Another innovation is the development of MADs with novel propulsion mechanisms. For instance, some new designs utilize magnetic attraction (like the Mandibular Advancement Magnetic Appliance, MAMA) to induce a mesializing movement of the jaw. This mechanism offers a different approach to traditional MADs, which often rely on mechanical linkages, and can be less affected by a patient's mandibular posture during sleep. The use of advanced materials like thermally molded PET-G (Polyethylene terephthalate glycol) also allows for the fabrication of thinner and more comfortable devices compared to traditional resin ones, enhancing resistance to fluid corrosion and reducing bulk inside the oral cavity. These material innovations contribute to increased patient comfort and device durability.

What Is the Broader Impact and Future Outlook for MADs?

The advancements in MAD technology are having a significant impact on sleep disorder management. The increased affordability and accessibility of MADs, particularly with advances in production and the possibility of purchasing customized devices, are making them a more viable option for a wider range of patients, especially in developing economies. This is crucial for individuals who may find CPAP machines or surgical procedures cost-prohibitive.

The growing public consciousness of sleep disorders is also a key driver. As more people become aware of the health risks associated with untreated sleep apnea and snoring, there's an increased demand for convenient and effective solutions. Education, coupled with better access to healthcare services and sleep studies, is making patients more proactive in seeking treatment.

The future of MAD technology is promising, with continuous research and development focused on creating even more sophisticated and user-friendly devices. This includes exploring further integration with telemedicine and remote monitoring platforms, allowing clinicians to track patient progress and make adjustments without the need for frequent in-person visits. The aim is to develop MADs that are not only highly effective but also seamlessly integrate into a patient's lifestyle, ensuring long-term compliance and improving the overall quality of life for individuals suffering from sleep apnea and snoring. As technology improves and insurance coverage expands, the adoption of MADs is expected to continue its upward trajectory globally.

Grids of Sensors in Non-Commutative Space

There's an idea of "non-commutative geometry" which seeks to view non-commutative algebras as if they were dual to some "non-commutative space" in the same way that commutative $C^*$-algebras (over the complex numbers) can be viewed as being the spaces of continuous complex valued functions on the locally compact Hausdorff space of that algebra's "spectrum" (or, specifically, the algebra of such functions that "vanish at infinity").

Some have considered this in the context of quantum mechanics, with the idea that, just as the operators for position along some axis and momentum along that axis, don't commute, perhaps the same is true for position along one axis and position along a different (orthogonal) axis. (I think there is the idea that this might help prevent some singularities in quantum gravity or something? idk. There's some kind of motivation for it.

This idea seems rather counterintuitive to me. With position and momentum not commuting (and their commutator being a constant, rather than some operator that could be zero in some states), and therefore things not having a simultaneously well defined position and momentum, this isn't too too hard to accept. Being able to say "here's the wavefunction in the position basis" and "here's the wavefunction in the momentum basis", seems nice enough. But, for position in one axis and in another axis to be not simultaneously well definable, seems harder to imagine. Like, if there was a maximum that the product of uncertainty in position and in momentum, could be.

The idea comes to mind of those simulations of "how it would look if you were walking around some city, if the speed of light was super slow". And then the question becomes, "if the degree of non-commutativity between different axiis was non-negligible, what would it look like?"

If one wants to consider the algebra for a quantum mechanical system with two non-commutative dimensions of space, one option is to consider the unital C^* algebra generated by self-adjoint operators q_x, q_y, p_x, p_y , subject to the relations: [q_x,p_x] = i hbar , [q_y, p_y] = i hbar , [q_x, p_y] = 0, [q_y, p_x] = 0 , [q_x, q_y] = i theta .

If one then takes the Hamiltonian for a 2D quantum simple harmonic oscillator, but using these q_x and q_y, and p_x and p_y , in place of the usual position and momentum operators, one can still do things like finding the spectrum of the Hamiltonian, etc. It turns out that one can even define some modified operators Q_x, Q_y, P_x, P_y in terms of our q_x, q_y, p_x, p_y , such that [Q_x, Q_y]=0 , P_x = p_x, P_y = p_y, and the Q_x, Q_y and the P_x, P_y have the same commutation relations with each-other as the normal position and momentum operators do. So, one can end up describing wavefunctions in the Q_x, Q_y basis or in the P_x, P_y basis, with Q_x and Q_y acting sorta like position, even though they aren't our actual position operators, and if we do this, then our simple harmonic oscillator defined in terms of q_x, q_y, p_x, p_y , ends up, when viewed in terms of Q_x, Q_y, P_x, P_y, being like a simple harmonic oscillator except with a term added for a magnetic field (proportional in strength to theta, and inversely proportional to hbar)

This is all stuff that I read about just recently. I'm not sure how it works in 3D. I imagine something similar, but the way of defining the Q_x and Q_y is probably substantially more complicated?

My idea (which others may have had before and investigated thoroughly, idk, I haven't done a literature search) is to, in order to think about "what things would look like in a world with non-commutative geometry (where the non-commutativity is large enough to be noticable at macroscopic scales) is to consider something like a "camera" made of a grid of detectors. Even though we don't really have a good notion of "points in space" in this kind of setting, we can still define an operator for "the distance between two particles" ( sqrt((q_{x,i} - q_{x,j})^2 + (q_{y,i} - q_{y,j})^2) ) and use this to write a Hamiltonian where there is a potential energy term which encourages each particle ("sensor") to be around some prescribed distance to each of its immediate neighbors, and then consider a ground state for this system. (Oh, q_{x,i} and q_{x,j} should commute with each-other btw. Operators for particle i and operators for particle j should commute with each-other. ) In order to say something to the effect of "our grid of sensors is located here in our lab, not moving", I think the grid should be labeled by pairs of integers between -N and N , and that the 4 corners should be "pinned" at certain coordinates (proportional to N) by replacing the position operators for those particles with just constants which should be coordinate for the particle in question. This is maybe somewhat unnatural because that would imply that at these corners the sensors there would have well defined coordinates in both x and y simultaneously (which would normally be impossible for particles in this non-commutative space), but we could just have those 4 particles not behave as sensors I guess. Anyway, if we take the limit as N goes to infinity, they would be far away from the origin, so hopefully this unnatural pinning wouldn't matter too much to things near the middle of the grid?

Then, if we want to ask about the location of some particle that isn't part of our grid of sensors, we can look at the projections for "is the distance between the particle and sensor j less than (some distance)?". Of course, these projections might not commute with each-other..? But, even if they don't, we can still use them for a Hamiltonian that represents particles being detected at whatever sensor they are nearby, and look at the probability distribution over "what detector was it detected at" that way, without needing to have "it is at detector i" and "it is at detector j" be commuting projections.

Oh, also, maybe should look at the limit where the masses of each the detectors are large (and equal to each-other), and/or where hbar is small, so that way the position vs momentum uncertainty doesn't play as large a role, just the uncertainty between x and y position?

If anyone has any thoughts on this, I'd like to hear it. (If you are aware of someone who has done this already, I'd especially like to hear it. I want answers, and I don't have time to work through stuff to find them, at least for now.)

Stepper Motors in Cars: The Unsung Heroes Behind Smooth Engine Performance

Have you ever wondered what keeps your car’s engine idling smoothly, manages airflow precisely, or ensures your acceleration feels just right? The answer might surprise you — it’s a stepper motor.

While small and often overlooked, stepper motors are critical to modern automotive systems. From controlling the throttle to regulating idle speed, these components operate behind the scenes to keep your engine efficient and your driving experience seamless.

What Exactly Is a Stepper Motor?

A stepper motor is a brushless electric motor that moves in precise, discrete steps. Each electrical pulse sent to the motor turns it slightly — often 1.8 or 0.9 degrees per step. This design allows for incredibly accurate positioning without needing feedback sensors. That’s why they’re widely used not just in cars, but also in 3D printers, CNC machines, and robotics.

Two Main Types of Stepper Motors in Automotive Use

Understanding stepper motors begins with recognizing their two core types:

Permanent Magnet (PM): Uses a rotor with permanent magnets. These motors offer high torque and precision, ideal for controlling critical systems like throttle position.

Variable Reluctance (VR): A simpler design without permanent magnets, generally cheaper and better for high-speed applications.

Inside a Stepper Motor: Key Components

Every stepper motor is made up of:

Rotor: The rotating core, often magnetized

Stator: The stationary housing with coils

Windings: Energized in a specific order to move the rotor

Shaft, bearings, and housing: Ensure smooth, reliable rotation

Electrical connectors: Link the motor to the vehicle’s ECU

Together, these parts enable the motor to deliver pinpoint control over movement.

Why Stepper Motors Matter in Your Car

In modern vehicles, stepper motors handle several essential tasks:

✅ Idle Speed Control (ISC)

Regulates air intake when the engine is idle, preventing stalls and maintaining fuel efficiency.

✅ Electronic Throttle Control (ETC)

Replaces the traditional throttle cable, providing smoother acceleration and better fuel economy.

✅ HVAC Airflow Management

Controls air dampers in your car’s ventilation system for accurate climate control.

Where Are Stepper Motors Located?

Typically found near or within the throttle body or intake manifold, stepper motors are designed for easy access and quick replacement.

Manual vs. Automated Stepper Motors

Some early or simplified designs use manual stepper motors, operated through basic circuits or switches — great for educational projects or legacy devices. However, modern vehicles rely on electronically controlled versions paired with stepper motor drivers for seamless automation.

Stepper Motor Drivers: The Hidden Brains

A stepper motor needs a driver to function. These drivers convert electrical pulses from the Engine Control Unit (ECU) into specific currents for the motor windings. Advanced drivers use microstepping for ultra-smooth movement and reduced noise.

Step-by-Step: How a Stepper Motor Works in a Car

The ECU analyzes RPM and engine load

Sends control pulses to the stepper motor driver

The driver activates stator windings in sequence

The rotor rotates step by step

This precise control loop is essential to smooth engine operation.

Signs Your Stepper Motor Might Be Failing

Here’s what to watch for:

Rough idling or RPM fluctuations

Check Engine Light with codes P0505–P0508

Increased fuel consumption (up to 15%)

Sudden stalling during deceleration

Why Do Stepper Motors Fail?

Common causes include:

Wrong driver settings → Overheating or damage

Loose wiring or poor connectors

Excessive engine heat or poor ventilation

Mechanical wear in bearings or shaft

Environmental exposure (dust, moisture)

Low-quality parts

Lack of preventive maintenance

Troubleshooting a Faulty Stepper Motor

Diagnosing issues usually involves:

Checking wiring and voltage with a multimeter

Testing resistance (normal range: 30–80 ohms)

Ensuring the driver sends correct pulse signals

Running test cycles with diagnostic tools

Listening for unusual noise or vibration

When Should You Replace a Stepper Motor?

Replace the motor if you notice:

Out-of-range resistance readings

Abnormal friction or binding in the shaft

Persistent error codes or failed test cycles

Do Stepper Motors Need Lubrication?

Generally no — these motors are sealed and maintenance-free. But if contamination occurs, use automotive-grade contact cleaner or silicone lubricant to clean the shaft (never apply oil to the windings).

How Much Do Stepper Motors Cost?

Prices (as of winter 2024 in Iran): 500,000 to 2,000,000 Tomans, depending on:

Car brand (OEM vs. aftermarket)

Motor specs (full-step vs. microstep)

Presence of feedback sensors

Choose a motor compatible with your vehicle model and ECU system.

Thinking About Removing It? Think Again.

Removing the stepper motor without ECU reprogramming can cause:

Idle speeds over 1500 RPM

Engine management system errors

Emissions violations (Euro 4+)

Legal trouble in regulated regions

Does It Affect Acceleration?

Not directly, but malfunctioning stepper motors can cause:

Delayed throttle response

Unstable air-fuel ratios

Reduced EGR system performance

Final Thoughts: Small Part, Big Impact

Despite their size, stepper motors are fundamental to engine stability, throttle accuracy, and fuel efficiency. Understanding how they work — and how to maintain or replace them — is vital for both DIY car enthusiasts and professional technicians.

A healthy stepper motor means a smoother drive, better fuel economy, and fewer unexpected repairs down the road.

Breakthrough in Deep-Layer Detection: High-Precision Application of JPMG Proton Magnetometer for Magnetic Anomaly Detection in 50m Overburden Layers

2. Overview of Magnetic Exploration Technology 2.1 Genesis of Magnetic Anomalies Magnetic minerals (e.g., magnetite, hematite, titanomagnetite) exhibit varying magnetization intensities under Earth’s magnetic field, causing local magnetic variations (“magnetic anomalies”). In 50m overburden environments, these signals are typically attenuated by surface disturbances, EM interference, and anthropogenic factors, complicating detection.
