The Triassic-Jurassic strata of the Newark Basin, USA: Acomplete and accurate astronomically-tuned timescale?
Authors: Tanner Lawrence H. , Lucas Spencer G.
Published: January 2024

Spectral analyses of apparent cyclicity of Triassic-Jurassic strata in the Newark Basin (New Jersey, USA) have been used to generate peak recurrence intervals within the sequence. When calibrated to sedimentation rates derived from varve counts in lacustrine mudstones, these recurrence intervals yield cycles inferred to correspond to orbital forcing at basic precession, eccentricity and long eccentricity frequencies. Consequently, the Newark basin cyclostratigraphy has been proposed as a floating astrochronology capable of providing a continuous high resolution geochronometry for most of the Late Triassic and part of the Early Jurassic. Indeed, orbitally-forced cyclicity does appear to be the dominant control of some portions of the Newark Basin section, particularly in the Lockatong and lower Passaic formations. But the application of the Newark Basin cyclostratigraphy as chronostratigraphy requires that the stratigraphic record is complete, i.e. no substantial erosional or depositional gaps exist, and cyclical throughout. Several lines of evidence indicate that these requirements are not met. Outcrop and core data demonstrate that portions of the Newark Basin stratigraphic section are non-cyclic, particularly in the fluvial-dominated strata of the upper Passaic Formation and the Stockton Formation. Correlation of available biostratigraphic data, including both pollen and conchostracan zones between the Newark Supergroup and the Germanic Triassic, indicates that most of Rhaetian and a portion of late Norian time is not represented by sediment in the Newark Basin and elsewhere in the Newark Supergroup. This suggests that at least 3 Myr of Late Triassic time is not recorded by strata in the Newark Basin. The inability of the Newark cyclostratigraphy to unambiguously locate and date the base of the Rhaetian or to produce a numerical age for the base of the Norian compatible with independently derived constraints demonstrate that the Newark Basin cyclostratigraphy is not a valid “floating astrochronology.” At best, only the middle late Carnian through early late Norian interval, about 10 Myr in duration, may be sufficiently complete to be useful for astrochronological purposes. In great part, the problems with utilizing the Newark Basin record as the basis for an astrochronology result from an inability to make unambiguous correlations to the marine record. Resolution of these issues and discrepancies could potentially be achieved through the collection of additional data, such as magnetostratigraphic data from continuous Upper Triassic marine sections.

Published: January 2024

This investigation of Upper Cretaceous and lower Paleogene sediments from the Tibetan Himalayas, based on three stratigraphic sections from the southern margin of Asian Plate and nine sections from the northern Indian Plate margin, provides the first high resolution biostratigraphic description of the region. The sedimentary successions from these two plate margins evolved during the following depositional stages, which we here divide into eleven new biozones (TLK2-3 and TP1-9); (i) an outer neritic stage from the Coniacian to the Maastrichtian, dominated by keeled planktonic foraminifera (PF), such as Globotruncana (TLK2); (ii) a latest Maastrichtian forereef assemblage dominated by Lepidorbitoides, Omphalocyclus and Orbitoides (TLK3); (iii) an early Paleocene, intermittently occurring backreef/shallow reefal warm environment with benthic assemblages dominated by small miliolids and rotaliids, such as Daviesina and Lockhartia (TP1-2); (iv) a late Paleocene-early Eocene, shallow reefal environment dominated by warm water forms, such as Alveolina, Assilina and Nummulites (TP3-7); (v) a depositional stage showing a slight deepening of the reef, with forereef assemblages, lasting until the end of the Ypresian (TP8); (vi) a final, early Lutetian depositional stage characterised by the complete disappearance of the larger benthic foraminifera (LBF) and their reefal environment, which was replaced by PF assemblages with intense reworking of pelagic facies triggered by the tectonics of the India-Asia collision (TP9). During the course of this study two unnamed species have been identified and described, Lepidorbitoides sp. A and Discocyclina sp. A, from the Xigaze forearc basin. The high resolution depositional and biostratigraphic scheme defined here for the southern Himalayan region gives greater insight into the general evolution of this globally important tectonic region.We have confirmed earlier observations that many LBF forms appear about 1Ma later in the eastern part of Tethys than they do in the west, reflecting their previously inferred gradual eastern paleogeographic migration. Additionally, this study has allowed us to refine the biostratigraphic ranges of some LBF of the Eastern Tethys, and for the first time to exactly correlate these Eastern Tethyan zones with the Shallow Benthic Zones (SBZs) of the Western Tethys.
Preface to Upper Paleozoic stratigraphy of the southwest United States
Authors: Wardlaw Bruce R. , Nestell Merlynd K.
Published: January 2024

This volume targets two areas of the American Southwest: the Guadalupe Mountains and Delaware basin, Texas, and the southern Inyo Mountains, California. In Texas, detailed lithostratigraphy of a complete section of the latest Guadalupian Reef Trail Member of the Bell Canyon Formation is presented for a better framework to study late Guadalupian events. Geochemical tephrochronologic frameworks are developed for the Rader Limestone Member of the Bell Canyon Formation and the Manzanita Limestone Member of the Cherry Canyon Formation to demonstrate the utility of geochemically identifying bentonites to show their correlation and to trace units from basin to shelf. In California, the general overall depositional regime of the Darwin basin of Mississippian to Early Permian rocks is presented along with focused studies of a short-lived Permian carbonate complex and of a latest Pennsylvanian-Permian major channel deposit.
Stratigraphic framework and biostratigraphic significance of the terminal Guadalupian Reef Trail Member, Bell Canyon Formation in the Patterson Hills, Type Guadalupian Area, Texas

Published: January 2024

The Reef Trail Member, Bell Canyon Formation, represents the uppermost subdivision of the Guadalupian Series (Capitanian Stage) of theMiddle Permian in its type area. Previouswork in the PattersonHills and in other parts of theDelaware basin have produced conodonts (e. g., Clarkina hongshuiensis) that provide a direct biostratigraphic correlation to latest Capitanian age rocks in the Lengwuan Stage (=Capitanian, latest Guadalupian, Middle Permian) in China. The conodont species Clarkina postbitteri, whichmarks the basal part of the Lopingian Series (Upper Permian), has not been found in the Middle Permian of West Texas. For the first time we describe complete detailed sections of the Reef Trail Member in order to provide a lithostratigraphic framework on which to base further biostratigraphic studies.We designate and describe a formal primary reference section for the Reef Trail Member because of the absence of a complete section in the type area. We also describe another complete section and two other important but incomplete sections, all in the Patterson Hills. The strata of all of the sections described were deposited in a basinal setting near the toe-of-slope, and are dominated by carbonate materials. Nearby outcrops contain toe-of-slope debris that provide evidence of mass wasting of the Capitan reef immediately prior to onset of evaporite deposition of rocks of the Castile Formation in the basin. Biostratigraphic and lithostratigraphic evidence indicate that evaporate deposition occurred simultaneously throughout the Delaware basin.
A new shelf-to-basin timeline for the Middle Permian (Guadalupian) Capitan Depositional System, West Texas and Southeastern New Mexico, USA

Published: January 2024

The correlation of the Rader Limestone Member of the Bell Canyon Formation to its shelf equivalent has varied over the years. Some models have equated it with the Seven Rivers Formation, and others to the Yates Formation, or a position straddling both units. More recent workers have used sequence stratigraphic models to refine this shelf-to-basin correlation, placing the “lower” part of the Rader Limestone Member in the Y3 high frequency sequence within the Yates Formation. Despite the presence of bentonites in both the Rader Limestone Member and the Yates Formation, and the potential to add a numerical age datum to the sequence stratigraphic hierarchy, geochemical tephrochronologic techniques have not yet been applied to the deposits. To address these issues, apatite phenocryst trace element chemistry was determined by electron microprobe analysis for samples from three bentonites collected from outcrop localities in Guadalupe Mountains National Park and two from the Gulf PDB-04 research well. Results are interpreted to indicate a correlation between a bentonite 16.5m above the base of the Rader at Back Ridge in the Patterson Hills of Guadalupe Mountains National Park, and one at 1956ft core depth in the PDB-04 core. Careful examination of the gamma-ray log for the well indicates that the 1956ft interval is in the Y3 high frequency sequence of Osleger and Tinker (1999). Further refinement can be made to the third cycle set of this high frequency sequence. Determining whether the bentonite at Back Ridge is in the “lower” or “upper” part of the Rader Member will require additional work. This correlation links the primary reference section for the basal through middle Capitanian Stage being established at Back Ridge with the shelf defined sequence stratigraphic framework. The sample from the Rader is the focus of U-Pb radioisotopic dating (Nicklen et al. in preparation) and would provide the first shelf-to-basin absolute age datum for the Capitan depositional system.
Regional implications of new chronostratigraphic and paleogeographic data from the Early Permian Darwin Basin, east-central California
Authors: Stevens Calvin H. , Stone Paul , Magginetti Robert T.
Published: January 2024

The Darwin Basin developed in response to episodic subsidence of the western margin of the Cordilleran continental shelf from Late Pennsylvanian (Gzhelian) to Early Permian (late Artinskian) time. Subsidence of the basin was initiated in response to continental truncation farther to the west and was later augmented by thrust emplacement of the Last Chance allochthon. This deep-water basin was filled by voluminous fine-grained siliciclastic turbidites and coarse-grained limestone-gravity-flow deposits. Most of this sediment was derived from the Bird Spring carbonate shelf and cratonal platform to the northeast or east, but some came from an offshore tectonic ridge (Conglomerate Mesa Uplift) to the west that formed at the toe of the Last Chance allochthon. At one point in the late Artinskian the influx of extrabasinal sediment was temporarily cut off, resulting in deposition of a unique black limestone that allows precise correlation throughout the basin. Deep-water sedimentation in the Darwin Basin ended by Kungurian time when complex shallow-water to continental sedimentary facies spread across the region. Major expansion of the Darwin Basin occurred soon after the middle Sakmarian emplacement of the Last Chance allochthon. This tectonic event was approximately coeval with deformation in northeastern Nevada that formed the deep-water Dry Mountain Trough.We herein interpret the two basins to have been structurally continuous. Deposition of the unique black limestone is interpreted to mark a eustatic sea level rise that also can be recognized in Lower Permian sections in east-central Nevada and central Arizona.
Architecture and evolution of an Early Permian carbonate complex on a tectonically active island in east-central California
Authors: Stevens Calvin H.
Published: January 2024

The newly named Upland Valley Limestone represents a carbonate complex that developed on and adjacent to a tectonically active island in east-central California during a brief interval of Early Permian (late Artinskian) time. This lithologically unique, relatively thin limestone unit lies within a thick sequence of predominantly siliciclastic rocks and is characterized by its high concentration of crinoidal debris, pronounced lateral changes in thickness and lithofacies, and a largely endemic fusulinid fauna. Most outcrops represent a carbonate platform and debris derived from it and shed downslope, but another group of outcrops represents one or possibly more isolated carbonate buildups that developed offshore from the platform. Tectonic activity in the area occurred before, probably during, and after deposition of this short-lived carbonate complex.

Aim: To investigate the effect of inferior pulmonary ligament dissection (PLD) on the development of residual pleural space and other complicationsafter upper lobectomy. Methods: We retrospectively analyzed the data of patients who
underwent upper lobectomy in our clinic between January23, 2011, and February26, 2013. Patients with a history of pulmonary tuberculosis,ipsilateral lung surgery, those that received neoadjuvant radiotherapy, those with a FEV1
value below 50%and those with two drains were excluded. Forty patients were included in the study and divided into two groups according to whether PLD was performed (Group I, n=20) or not performed (Group II, n=20).Complications
that developed, negative aspiration requirement, additional thoracic drain requirement, duration of drain in place, hospital stay, and percentage of the pleural space on chest X-ray were recorded. The results were statistically
compared between the groups. Results: Of the patients, 34(85%) were male, and the mean age was 60.5 (38-78) years. Right upper lobectomy was performed in 24(60%) patients (55% Group I, 45% Group II). Postoperative complications
were detected in 16(40%) patients (45% Group I, 35% Group II). The most common complication was prolonged air leak seen in eight (20%) patients (15% Group I, 2.25% Group II). The mean duration of drain in place was 8 days (7days
Group I, 9 days Group II, p=0.62). Conclusion: From the results of our study, PLD had no positive or negative effect on pleural space or complications in patients who underwent upper lobectomy.
Machine Learning Application for Early Power Analysis Accuracy Improvement: A Case Study for Nets Switching Power

Published: January 2024

In the quest for precise power estimation during the early phases of design, the absence of a Standard Parasitic Exchange File (SPEF) with interconnect R/C values poses a significant hurdle. To address this challenge, we introduce a Machine Learning (ML) approach designed to predict net power metrics at the Gate Level without relying on SPEF. Net features are extracted from Electronic Design Automation (EDA) tools, facilitating the training of models for the prediction of Net Switching Power. Notably, the Random Forest model emerges as the most effective, achieving high accuracy by reducing power error from around 20% to a mere 0.1%.Furthermore, our innovative approach enhances efficiency by bypassing the traditional SPEF generation process. This results in a significant 5x reduction in runtime compared to the conventional flow, with a notable decrease from 163.6 minutes to just 33.7 minutes. This substantial acceleration is achieved by skipping the time-intensive synthesis and physical design steps required for SPEF.In summary, our ML-based methodology not only achieves swift and accurate power estimation in the early stages of design but also liberates the process from the constraints of SPEF dependency. This marks a transformative shift in the landscape of power estimation methodologies.

Published: January 2024

This work presents a monolithic microwave integrated circuit (MMIC) based power amplifier (PA) with single 150 nm GaN high electron mobility transistor (HEMT) using broadband matching. For the proposed amplifier, two stage L-type biasing network is designed. In order to provide good linearity, low Q, broader bandwidth and optimized chip area, band pass filter (BPF) type matching network is proposed. The topology and parameter selection is done by performing proper load pull analysis. This helps in achieving wide band matching to maintain low Q factor. Thus the proposed amplifier is evaluated with post layout EM simulation data. For the 26 GHz band of 5G communication, proposed amplifier has a small signal gain of 11 dB for 21-27.4 GHz. The amplifier offers 33.42 dBm saturated output power and good linearity. The designed PA provides 31.35 dBm output power, 26% power added efficiency (PAE) and 29% drain efficiency (DE) at 1 dB compression with IP3 of 39.67 dBm for 26 GHz band. The designed PA has less complexity and small chip area of 4.3 mm2.

Published: January 2024

Random Telegraph Noise is a relevant source of variability in integrated circuits and a growing issue due to device scaling. Jitter is  one of its consequences; therefore, it is an important parameter of performance measurements for electronic components and systems. In this paper, the relationship between Random Telegraph Noise and different concepts of jitter is studied. Firstly, a gate delay variability study of a CMOS inverter is discussed. Then, an absolute, a periodic, and a cycle-to-cycle jitter are evaluated in a five-stage ring oscillator. All the data were generated with a spice simulator modified to properly account for Random Telegraph Noise, using the Monte Carlo technique.

Published: January 2024

The ever-increasing growth in digital video consumption motivates the research and development of new video coding standards to improve coding efficiency. Among the several new tools that the Versatile Video Coding (VVC) standard introduced lies the Quadtree Plus Multi-Type Tree (QT+MTT), which improves upon the quadtree of High Efficiency Video Coding (HEVC) in terms of coding efficiency. Nevertheless, such improvements come at the cost of increased complexity. Hence, to meet the real-time and energy efficiency requirements, embedded devices must adopt techniques to effectively reduce the VVC complexity, including customized hardware accelerators. This work presents a low-energy hardware architecture design for the Fractional Motion Estimation (FME), one of the most critical steps of HEVC and VVC encoders. The proposed architecture supports the Switchable Interpolation Filter (SIF) of VVC and was synthesized to enable Variable Block Size (VBS) from 8×8 up to 128×128 sized blocks so that it can perform the FME of most partitions of the QT+MTT from VVC. The results show increases of at most 4.52% in area and 10.79% in total power for the extra hardware needed to support VBS, and up to 9.15% and 15.72%, in area and power, respectively, for supporting up to 128×128 block sizes.

Published: January 2024

The affine prediction is the main novelty in the inter-frame prediction of Versatile Video Coding (VVC) standard. However, implementing the affine prediction requires a huge computational effort that makes mandatory the use of dedicated hardware accelerators to achieve real-time processing and meet the constraints of area and power dissipation for mobile devices. In light of this, this work presents different approaches for a hardware design dedicated to solving the linear equation system, which is essential for refiningthe affine Motion Vector. Synthesis results show that the High- Throughput architecture, which explores the parallelism of internal operations, can reach an accuracy of 99.99%, requiring 333.9kgates to be implemented and presenting a power dissipation of 120.4mW when running at 540MHz, the operational frequency required to process 60 frames per second of HD 1080p videos.
New Approach of deriving Third-Order Quadrature Sinusoidal Oscillators
Authors: Raj Ajishek
Published: January 2024

Numerous approaches/methods have been employed in the past to derive various third-order sinusoidal oscillators (TOSOs). In this communication, a new simple approach for realizing TOQSO is presented, utilizing a second order inverse high-pass active filter with a cascade connection of traditional lossless integrator. The proposed approach can provide quadrature voltage outputs by leveraging the availability of lossless integrator. It is demonstrated that the proposed approach has the potential to generate various TOQSOs, as exemplified by the voltage-mode TOQSO based on current feedback operational amplifiers (CFOAs). The oscillation condition (CO) and frequency (FO) of the derived oscillator can be independently controlled. Experimental results utilizing AD844 CFOA ICs have been included to validate the theoretical propositions.
Design of a multi-standard IR-UWB emitter in a 28 nm FD-SOI technology based on the frequency transposition pulse synthesis
Authors: Artemio Schoulten Felipe , Vauche Rémy , Gaubert Jean , Bourdel Sylvain , Augusto Mariano André
Published: January 2024

Ultra-WideBand Impulse Radio (IR-UWB) is a wireless communication technology well-suited for short range communications (about 10 meters) and has the advantage to allow real-time location with a precision of 5 cm. However, its use has been standardized in some standards and especially in the IEEE 802.15.4 dedicated to Wireless Personnal Area Network (WPAN) and in the IEEE 802.15.6 dedicated to Wireless Body Area Network (WBAN). After presenting requirements of each standard and a literature survey on the IR-UWB emitter, the design of a multi-standard IR-emitter based on the frequency transposition pulse synthesis is proposed in a 28 nm FD-SOI technology. The proposed design has been validated at the transistor level using electrical simulations which take into account the parasitic capacitance at each critical node of the circuit. Moreover, results show that the proposed circuit has the potential to be the first multi-standard IR-UWB emitter which covers every channel of the IEEE 802.15.4 and 802.15.6 standards.

Published: January 2024

To achieve ultra-high-speed wireless communications, millimeter-wave bands have emerged as bands of interest for these new applications. However, a technological breakthrough linked to power amplifiers has appeared. Indeed, working near the maximum oscillation frequency of the transistor leads to low intrinsic gain and poor efficiency for these devices. This paper presents an overview of sub-terahertz CMOS power amplifiers with a focus on gain enhancement techniques. The paper will also feature state-of-the-art D-Band CMOS power amplifier architectures. The goal is to present how the gain enhancement techniques are used in a complete architecture. Based on the three techniques and the state-of-the-art presented in the paper, a focus on three architectures is proposed. The aim is to highlight the benefits of each method in the design. The final part summarizes the paper and opens up future perspectives and trends identified through the paper.

Published: January 2024

The Versatile Video Coding (VVC) is a new standard released in 2020 and is considered the state-of-the-art technology in video coding. It introduces several innovative tools to achieve high coding efficiency, but, on the other side, requires a significantly higher computational effort. One of the innovations of the standard is the Multiple Transform Selection (MTS), which plays a crucial role in improving coding efficiency. MTS supports square and rectangular transform blocks and includes three transform types (DCT-II, DCT-VIII, and DST-VII) that can be combined in horizontal and vertical directions. As a result, VVC codecs must support a wide range of transform types and formats, making the development of hardware solutions essential to enable real-time processing. This work presents a dedicated hardware architecture for all inverse transforms in the VVC decoder. The proposed architecture performs one-dimensional transforms for all sizes supported in the VVC standard, allowing for the combination into 2D square and rectangular transforms, ranging from 4×4 to 64×64 blocks for IDCT-II and from 4×4 to 32×32 for IDCT-VIII and IDST-VII. The proposed architecture can process videos of up to UHD 8K@60fps resolution in real time, with a power consumption of 778 mW.

Digital libraries and scientific literacy as a source of knowledge to preserve human civilization and libraries as public institutions that acts as service providers and information providers. The development of science and technology in the current era has ushered in the process of obtaining scientific information very easily which accompanies humans freely without being selective in obtaining information only through smartphones, computers, the web and other social media. This study was carried out in a library and the samples were visitors and people around the library who used male and female classifications. The data that has been collected will be analyzed using two forms of analysis, namely quantitative and qualitative. The findings of this study are that there are differences in tendencies in choosing reading sources or sources of scientific information between men and women. Women are more dominant in using digital scientific literacy via smartphones and via the internet, while men prefer to visit the library to read and search for scientific literacy. The existence of libraries in the digital era still contributes to increasing people's reading interest even though people's reading interest is still in the low category.

Published: January 2024

Plankton is an aquatic biota that lives following the currents in the water.  The life of plankton is highly dependent on the water quality in those aquatic environments. The constantly changing physical and chemical conditions of water lead to fluctuations in the abundance of plankton in a water. This study aims to analyze fluctuations in plankton abundance and its correlation with water quality in Percut Sei Tuan Waters. The study was conducted in February and March 2023. Filtration method at 3 stations is the Sampling technique used in this study. The sampling period is carried out in the morning, afternoon, and evening. Data analysis to determine the relationship between variables using Pearson correlation in SPSS version 26. Based on the research results, 42 genera of phytoplankton and 16 genera of zooplankton were found. The highest abundance of phytoplankton was 4.635 Ind/L during the afternoon. The highest abundance of zooplankton was obtained at evening, which was 1.049 Ind/L. This is due to the daily vertical migration of zooplankton and their negative phototactic behavior, while phytoplankton require light for photosynthesis. The research results indicate that the abundance of phytoplankton has a very strong correlation with temperature, light intensity, salinity, TSS, pH, DO, and Nitrate. The abundance of zooplankton is highly correlated with water flow velocity, light intensity, salinity, TSS, TDS, pH, DO, Nitrate, and Phosphate.

Published: January 2024

Thinking styles and metacognition are related as they both have the same space in assessing one’s own abilities. Metacognition and thinking styles have an important role in unlocking the potential of physics problem solving. The objective of this study is to investigate the relationship between metacognition, thinking styles (particularly those proposed by Gregorc), and physics problem solving. The study involved a cohort of 364 students who were pursuing a physics degree at Tadulako University. The results indicated that metacognition behavior exhibited in the process of solving physics problems was classified as high category. The most dominant thinking style was abstract sequential, while the least was concrete random. The data analysis showed a significant difference in metacognition behavior between groups categorized by thinking style. Specifically, the concrete sequential (SK) group exhibited a significant difference with the abstract random (AA) group. These results provide further understanding of how metacognition and thinking styles play a role in physics problem solving. This study contributes significantly to comprehending the connection between metacognition, thinking styles, and the successful resolution of physics problems. The insights gained provide prospects for formulating more efficient physics learning methods that will ameliorate students' aptitude in tackling physics problems.

The interaction between International Humanitarian Law and International Human Rights Law regarding the protection of the right to life during armed conflicts
Authors: Soares João Pedro Quintela
Published: January 2024

Desenvolvimentos na jurisprudência internacional e regional reconheceram a sobreposição do Direito Internacional Humanitário e do Direito Internacional dos Direitos Humanos em diferentes domínios. No entanto, a distinta lógica sobre a qual os ramos foram construídos pode oferecer soluções distintas no que tange à proteção do direito à vida. Tendo-se em consideração as indicações do Tribunal Internacional de Justiça e dos principais organismos de direitos humanos, há ainda obstáculos a serem superados no entendimento da interação entre os dois ramos. O presente trabalho visa analisar esses desafios e responder à questão de saber como efetivamente a complementaridade e o princípio da lex specialis devem ser aplicados com vista à máxima proteção dos indivíduos e à coerência sistemática jurídico-internacional.
As perspectivas da atual política migratória portuguesa em relação aos nômades digitais a partir da análise econômica do direito
Authors: Chaccur Ricardo
Published: January 2024

Dentre os países europeus que se tornaram um destino comum dos fluxos migratórios no século XXI, Portugal contabilizou 757.252 cidadãos estrangeiros a residir no país em 2022, de acordo com os dados do Serviço de Estrangeiros e Fronteira do país, e que representa pelo sétimo ano consecutivo um aumento da população migrante no país. Diante do aumento da população estrangeira residente no país, observa-se, também, uma crise na política migratória portuguesa decorrente dos questionamentos e críticas ao funcionamento do SEF, causados pelas constantes reclamações pela falta de agendamentos que colocam imigrantes em situação irregular no país e que dificultam o acesso à direitos fundamentais como saúde, educação, acesso à justiça e habitação. Diante do aumento dos casos de xenofobia, abusos laborais e muitos outros problemas que demonstram a fragilidade da atual política migratória, de responder às necessidades da sociedade portuguesa, a questão migratória se tornou uma pauta obrigatória do atual governo e as discussões e debates em torno da questão para se evitar impactos ainda mais graves aos já existentes resultou na Lei 18/2022 que teve como objetivo promover alterações na atual Lei de Estrangeiros do país e tentar a partir desses mecanismos organizar e coordenar a entrada de estrangeiros nos país. Contudo, a inovação trazida pela nova lei que possibilita a concessão de visto para os nômades digitais tem gerado polêmicas e críticas ante o aumento das rendas nas principais cidades portuguesas decorrente do aquecimento do mercado imobiliário, e a necessidade de se analisar se esta política migratória é adequada na busca pela maximização de riquezas preconizada pela Teoria da Análise Econômica do Direito.
