Measuring the Effectiveness of the 'Batch Operations' Energy Design Pattern to Mitigate the Carbon Footprint of Communication Peripherals on Mobile Devices.

The Internet of Things (IoT) is set to play a significant role in the future development of smart cities, which are designed to be environmentally friendly. However, the proliferation of these devices, along with their frequent replacements and the energy required to power them, contributes to a significant environmental footprint. In this paper we provide scientific evidences on the advantages of using an energy design pattern named 'Batch Operations' (BO) to optimize energy consumption on mobile devices.

Opto-twistronic Hall effect in a three-dimensional spiral lattice.

Studies of moiré systems have explained the effect of superlattice modulations on their properties, demonstrating new correlated phases. However, most experimental studies have focused on a few layers in two-dimensional systems. Extending twistronics to three dimensions, in which the twist extends into the third dimension, remains underexplored because of the challenges associated with the manual stacking of layers.

Acute urinary retention in children: causes and the role of bladder catheterization and ultrasonogram.

Background: Acute urinary retention in children is uncommon and can be related to several causes. The role of abdominal ultrasound and catheterization is controversial. We aimed to identify the most common causes of acute urinary retention in children, focusing, particularly on the role of bladder catheterization and the diagnostic value of acute ultrasound.

Investigating How the Properties of Electrospun Poly(lactic acid) Fibres Loaded with the Essential Oil Limonene Evolve over Time under Different Storage Conditions.

Essential oils have been identified as effective natural compounds to prevent bacterial infections and thus are widely proposed as bioactive agents for biomedical applications. Across the literature, various essential oils have been incorporated into electrospun fibres to produce materials with, among others, antibacterial, anti-inflammatory and antioxidant activity. However, limited research has been conducted so far on the effect of these chemical products on the physical characteristics of the resulting composite fibres for extended periods of time.

Risk Factors for Failure of Endoscopic Balloon Dilatation of Primary Obstructive Megaureter: Single-Center 12-Year Experience with 123 Cases.

To review our experience with >100 patients with primary obstructive megaureter (POM) undergoing endoscopic balloon dilatation (EBD) and a follow-up of up to 12 years and determine potential risk factors for failure. Our hypothesis is that EBD allows for long-term treatment in >80% of patients, and its effectiveness decreases in more severe cases. This is a retrospective study of 123 consecutive patients (131 ureters) undergoing EBD from 2009 to 2021.

Geometric Similarities and Topological Phases in Surface Magnon Polaritons.

Surface polaritons have proven to be uniquely capable of controlling light-matter interactions. Here we explore surface magnon polaritons in low-loss ferrimagnetic semiconductors, with a focus on their topological phases. We propose several surface magnon polariton devices, including microwave resonators that can strongly enhance magnetic fields and low-loss interconnects joining waveguides with vastly different impedances.

Berry Curvature Spectroscopy from Bloch Oscillations.

Artificial crystals such as moiré superlattices can have a real-space periodicity much larger than the underlying atomic scale. This facilitates the presence of Bloch oscillations in the presence of a static electric field. We demonstrate that the optical response of such a system, when dressed with a static field, becomes resonant at the frequencies of Bloch oscillations, which are in the terahertz regime when the lattice constant is of the order of 10 nm.

Vacuum-assisted Mini-percutaneous Nephrolithotomy for 2-3-cm Renal Stones: A Comparative Study with Retrograde Intra-renal Surgery.

Purpose: To compare vacuum-assisted percutaneous nephrolithotomy (VAmini-PCNL) with retrograde intra-renal surgery (RIRS) for the treatment of renal stones measuring 2-3 cm in diameter.

Material And Methods: This retrospective study included children receiving treatment for pyelocalyceal stones of 2-3 cm in diameter from November 2018 to September 2022. Consecutive patients undergoing VAmini-PCNL after 2020 were compared with a historically matched group undergoing RIRS.

Roses in the nonperturbative current response of artificial crystals.

In two-dimensional artificial crystals with large real-space periodicity, the nonlinear current response to a large applied electric field can feature a strong angular dependence, which encodes information about the band dispersion and Berry curvature of isolated electronic Bloch minibands. Within the relaxation-time approximation, we obtain analytic expressions up to infinite order in the driving field for the current in a band-projected theory with time-reversal and trigonal symmetry. For a fixed field strength, the dependence of the current on the direction of the applied field is given by rose curves whose petal structure is symmetry constrained and is obtained from an expansion in real-space translation vectors.

Optically Induced Symmetry Breaking Due to Nonequilibrium Steady State Formation in Charge Density Wave Material 1T-TiSe.

The strongly correlated charge density wave (CDW) phase of 1T-TiSe is of interest to verify the claims of a chiral order parameter. Characterization of the symmetries of 1T-TiSe is critical to understand the origin of its intriguing properties. Here we use very low-power, continuous wave laser excitation to probe the symmetries of 1T-TiSe by using the circular photogalvanic effect.

Where is the testis? The role of ultrasound and diagnostic laparoscopy for Crossed Testicular Ectopia (CTE): Case report and review of literature.

Crossed Testicular Ectopia (CTE) or transverse testicular ectopia is an anecdotic urogenital anomaly in which both testes are located on the same side, generally associated with a patent processus vaginalis (PPV). The condition can be detected by ultrasound. Nevertheless, the diagnosis is often missed preoperatively and CTE is recognized intraoperatively.

Quantum Geometric Oscillations in Two-Dimensional Flat-Band Solids.

Two-dimensional van der Waals heterostructures can be engineered into artificial superlattices that host flat bands with significant Berry curvature and provide a favorable environment for the emergence of novel electron dynamics. In particular, the Berry curvature can induce an oscillating trajectory of an electron wave packet transverse to an applied static electric field. Though analogous to Bloch oscillations, this novel oscillatory behavior is driven entirely by quantum geometry in momentum space instead of band dispersion.

Pictures of a crisis. Destination marketing organizations' Instagram communication before and during a global health crisis.

The COVID-19 pandemic enhanced social media communications at a time individuals were unable to leave their homes due to the lockdown measures. A lack of research has been identified on how destination marketing organizations use social media during global health crises. Addressing this gap, the present research uses a mixed-method approach to examine the use of Instagram by Milan and Paris' Destination Marketing Organizations before and during COVID-19 and user engagement with it.

Pyelo-ureteral junction obstruction in poorly functioning kidneys: Does conservative management play a role in pediatric patients?

Background: Management of Pyelo-ureteral Junction Obstruction (PUJO) in poorly functioning kidneys in pediatric patients is still controversial, particularly regarding the role of conservative treatment.

Aim: To evaluate and present the outcomes of internal diversion and follow-up results of a small series of pediatric patients with UPJO in poorly functioning kidneys.

Study Design: Retrospective review of 17 consecutive patients with unilateral PUJO in kidneys with Differential Renal Function (DRF) <20% undergoing temporary internal urinary diversion between 2009 and 2021 at a single tertiary center.

General duality and magnet-free passive phononic Chern insulators.

Integrated phononics plays an important role in both fundamental physics and technology. Despite great efforts, it remains a challenge to break time-reversal symmetry to achieve topological phases and non-reciprocal devices. Piezomagnetic materials offer an intriguing opportunity as they break time-reversal symmetry intrinsically, without the need for an external magnetic field or an active driving field.

A Sustainable Approach to Delivering Programmable Peer-to-Peer Offline Payments.

Payment apps and digital wallets are powerful tools used to exchange e-money via the internet. However, with the progressive disappearance of cash, there is a need for the digital equivalent of physical banknotes to guarantee the same level of anonymity of private payments. Few efforts to solve the double-spending problem exist in P2P payments (i.

Polaritonic Chern Insulators in Monolayer Semiconductors.

Systems with strong light-matter interaction open up new avenues for studying topological phases of matter. Examples include exciton polaritons, mixed light-matter quasiparticles, where the topology of the polaritonic band structure arises from the collective coupling between matter wave and optical fields strongly confined in periodic dielectric structures. Distinct from light-matter interaction in a uniform environment, the spatially varying nature of the optical fields leads to a fundamental modification of the well-known optical selection rules, which were derived under the plane wave approximation.

Electrospinning of honey and propolis for wound care.

Phytochemicals and naturally derived compounds, such as plant extracts and bee products, are regarded as complementary and alternative medicines for the treatment of skin wounds, due to their antibacterial, anti-inflammatory, and antioxidant properties. In recent years, it has been shown that dressings impregnated with honey (particularly Manuka honey) are effective for the topical treatment of wounds and burns, and some of them are currently used in clinics. This has stimulated the development of more advanced dressings based on polymeric nanofibres that can release honey and other bee products (like propolis) to promote wound healing.
