Beleaguered wind farm operator Orsted announced Thursday that it intends to cut up to 2,000 jobs toward the end of 2027, in a bid to become more competitive and refocus its efforts on Europe.
The company has faced headwinds this year as President Donald Trump’s administration clamped down on wind power generation in the United States.
Orsted’s shares were 1% higher in early European trade on Thursday.

In this study, the calibration factor necessary for quantitative SPECT analysis was derived by dividing the known activity concentration. For the dosimetric calculation, the STP voxel-based dosimetry using the Hanschied approach was employed to calculate the absorbed dose in the kidneys and tumours based on the SPECT images acquired approximately 48 hours after administration.
The mean and SD of kidney absorbed dose were 2.04 Gy ± 0.37 Gy (range 1.71 to 2.67 Gy). The absorbed doses within tumours showed considerable variation across the twenty-five tumours analysed, which were derived from eight treatment cycles. Tumour absorbed doses ranged from a low of 0.98 Gy to a high of 16.05 Gy. The mean absorbed dose to the tumours was 5.14 Gy, the SD was 3.81 Gy, as detailed in the box plot in Figure 3.

Quantitative voxel-based dosimetry was carried out for five patients (P1–P5) over eight treatment cycles (C1–C8), with imaging acquisition performed between 48 and 52 hours post-therapy. The absorbed radiation doses to the kidneys and selected tumour sites are summarised in Table 2.
Across all patients, the kidney absorbed doses remained within a relatively narrow range, suggesting consistent radiopharmaceutical handling and organ tolerance. For Patient P1, who underwent three treatment cycles (C1–C3), the kidney dose started at 1.99 Gy in C1, rose to 2.66 Gy in C2, and then dropped slightly to 2.23 Gy in C3. This fluctuation may reflect changes in bio-distribution or renal clearance over time.
Patients P2 and P3, each evaluated during one or two cycles (C4–C6), had similar kidney doses, consistently measured at 1.71 Gy, despite variation in tumour load and lesion location. Patient P4 (C7) received 1.88 Gy, while Patient P5 (C8) had the highest kidney dose at 2.46 Gy. Notably, none of the patients exceeded the generally accepted renal threshold, supporting the safety of the administered activity levels in this cohort.
Tumour dosimetry revealed a broader range of absorbed doses, reflecting both inter-patient and intra-patient variation. In Patient P1, lung lesions demonstrated a downward trend across three consecutive cycles, with the left lung receiving 8.54 Gy, 7.67 Gy, and 4.20 Gy in C1, C2, and C3, respectively. Similarly, the right lung showed a decrease from 5.92 Gy to 3.17 Gy. This decline likely indicates therapeutic response, consistent with expectations following multiple cycles of targeted radionuclide therapy (as illustrated in Figure 4).

Whole-body SPECT/CT at 48 hours post-administration demonstrates good tracer uptake in multiple lungs, left adrenal, and bone metastases, with physiological uptake in salivary glands, liver, spleen, and bowel. Markings indicate a decrease in lung lesions across treatment cycles
Patient P2 showed tumour doses between 1.93 and 5.53 Gy in spinal and rib lesions. Though the absorbed doses remained moderate, a slight decrease was observed in the second cycle (C5), particularly in the rib and sternum, which may suggest early response to treatment or subtle changes in radiotracer uptake.
In Patient P3 (C6), tumour absorbed doses were lower and more uniform, ranging from 1.55 to 2.69 Gy, covering thoracic and lumbar vertebrae. In contrast, Patient P4 (C7) demonstrated a much higher dose to the lumbar spine, reaching 16.05 Gy, the highest tumour dose recorded in this study. Additional lesions in the lung and pelvis received 4.18 Gy and 3.76 Gy, respectively.
Patient P5 (C8) also presented with high skeletal uptake. The lumbar spine lesion received 13.00 Gy, while T-spine and pelvic lesions ranged from 6.03 to 10.03 Gy. These findings reflect intense PSMA expression in metastatic bone lesions and underline the heterogeneity of tumour dose distribution in advanced disease.

Remarks prepared for delivery
Distinguished guests, colleagues, friends. Good afternoon.
I am very pleased to join you here at the 6th Global Fintech Fest in Mumbai – a financial hub celebrated for its rich history, vibrant culture and, most importantly, enduring spirit of innovation.
Today, central banks operate in a world of rapid transformation. Technology has reshaped not only how financial services are delivered but also how central banks interact with external stakeholders. Artificial intelligence (AI) stands at the centre of this transformation.
In my speech this afternoon, I will explore how central banks are using AI to support their operations, the challenges AI poses and strategies to address the trade-offs central banks encounter in order to reconcile the risks and benefits.
The adoption of AI has extended to central banks, where it has the potential to enhance efficiency, improve accuracy and strengthen decision-making processes. AI is making significant impact in three key areas:
1) Data analysis
2) Economic forecasting and policy analysis
3) Payment system oversight and global connectivity
While the benefits of AI are undeniable, its integration into central banking presents challenges, particularly in monetary policy and financial stability. Here are some pressing issues:
1) Key technological limitations of AI
2) Monetary policy and transmission effectiveness
AI presents several challenges to monetary policy and its transmission mechanisms, as highlighted in a recent ECB speech and our annual economic report. 3
3) Financial stability risks
The integration of AI into financial systems presents financial stability risks that central banks and policymakers must address:
4) Cyber risks and ethical considerations
As central banks explore the transformative potential of AI, they face complex trade-offs that demand careful consideration:
Overall, achieving the right balance between performance, cost and control is vital for central banks to successfully adopt AI. Central banks must thoughtfully evaluate immediate short-term investments against the long-term benefits.
So how can institutions like the BIS help central banks navigate the evolving landscape of AI? At the BIS, we provide support to central banks through three key avenues:
1) Forum for discussion
We offer a space for central banks to exchange insights and build a community around emerging technologies.
2) Platform for international cooperation
We facilitate collaboration among central banks and regulators to uphold monetary and financial stability.
3) Experimental innovation
Through the BIS Innovation Hub, we enable central banks to experiment with cutting-edge technologies.
By fostering discussion, collaboration and experimentation, the BIS helps central banks to harness the potential of AI while mitigating risks.
To conclude, AI presents transformative opportunities for central banks, enhancing efficiency, decision-making and financial infrastructure. From advanced data analysis to improved oversight of payment systems, AI is already reshaping central bank operations. However, challenges such as data quality, model complexity, ethical concerns and financial stability risks must be carefully addressed.
To fully realise the potential of AI, central banks must balance its benefits with its risks. Transparency, robust governance and talent development are essential to navigating this evolving landscape.
As stewards of monetary and financial stability, central banks have a responsibility to adopt AI in a safe, ethical and sustainable manner. The BIS is dedicated to supporting this journey by fostering dialogue, promoting international cooperation and enabling innovation.
Thank you.
